洗衣机设计毕业论文本篇论文将对洗衣机相关设计进行探讨。

首先介绍了洗衣机的历史和现状，接着结合人体工程学、功能需求和节能环保三个方面，探讨了洗衣机设计的一些关键点，包括控制面板、门、洗涤模式、水位控制等。

最后，本文根据以上分析提出了一些改进方案和设计思路，旨在提高洗衣机的实用价值和用户体验。

一、引言洗衣机是家庭中必不可少的电器产品之一，它的出现大大方便了我们的生活。

随着社会的发展，人们对于洗衣机的功能和外观要求也越来越高。

因此，一款好的洗衣机不仅需要具备实用性，还需要兼顾外观设计、功能完善以及质量稳定等多个方面。

本文将针对洗衣机的设计方面进行探讨，以期为洗衣机的设计提供一些参考意见。

二、洗衣机的历史和现状自20世纪初洗衣机出现以来，经过多次技术升级和改进，已成为现代生活中不可或缺的一部分。

目前市场上的洗衣机种类繁多，主要分为滚筒式和波轮式两大类。

其中，滚筒式洗衣机由于具有洗涤效果好、衣物洗后烘干程度高等优点，成为目前市场中的主流产品。

然而，同时我们也需要看到，目前市场上的洗衣机在外观设计、功能方面还存在一定的不足，如控制面板的设计繁琐、门口位置容易堵塞等问题。

为此，本文将根据人体工程学、功能需求和节能环保三个方面共同对洗衣机的设计进行探讨和改进。

三、人体工程学的角度人体工程学是一门研究人得活动和作业与环境之间相互关系的学科，将人的生理、心理等特性作为设计对象的一部分，以达到更好的用户体验与工作效率。

对于洗衣机的设计来说，人体工程学同样也扮演着重要的角色。

1、控制面板的设计洗衣机的控制面板设计应该尽可能的简洁、易操作，减少操作盲区。

例如,细小的按钮会使用户难以准确判断，并在操作时误按其他按钮，降低洗衣机集成性能。

因此，我们应该尽可能提高按钮的大小，避免遮挡等。

2、门的设计现阶段洗衣机的门设计多为前置式，这种设计方便拿取衣物，但也存在一个问题，就是当衣物取出时，衣物常常会挡住门口，给下一次使用带来了很大的麻烦。

The Sunflower Seed Huller and Oil PressBy Jeff Cox-- from Organic Gardening, April 1979, Rodale PressIN 2,500 SQUARE FEET, a family of four can grow each year enough sunflower seed to produce three gallons of homemade vegetable oil suitable for salads or cooking and 20 pounds of nutritious, dehulled seed -- with enough broken seeds left over to feed a winter's worth of birds.The problem, heretofore, with sunflower seeds was the difficulty of dehulling them at home, and the lack of a device for expressing oil from the seeds. About six months ago, we decided to change all that. The job was to find out who makes a sunflower seed dehuller or to devise one if none were manufactured. And to either locate a home-scale oilseed press or devise one. No mean task.Our researches took us from North Dakota -- hub of commercial sunflower activity in the nation -- to a search of the files in the U.S. Patent Office, with stops in between. We turned up a lot of big machinery, discovered how difficult it is to buy really pure, unrefined vegetable oils, but found no small-scale equipment to dehull sunflowers or press out their oil. The key to success, however, was on our desk the whole time. In spring 1977, August Kormier had submitted a free-lance article describing how he used a Corona grain mill to dehull his sunflower seeds, and his vacuum cleaner exhaust hose to blow the hulls off the kernels. A second separation floated off the remaining hulls, leaving a clean product. We'd tried it, but because some kernels were cracked and the process involved drying, we hadn't been satisfied. Now we felt the best approach was to begin again with what we learned from Mr. Kormier and refine it.Staff Editor Diana Branch and Home Workplace Editor Jim Eldon worked with a number of hand- and electric-powered grain mills. While the Corona did a passable job, they got the best results with the C.S. Bell #60 hand mill and the Marathon Uni Mill, which is motor-driven. "I couldn't believe my eyes the first time I tried the Marathon," Diana says. "I opened the stones to 1/8th inch, and out came a bin full of whole kernels and hulls split right at the seams. What a thrill that was!"She found that by starting at the widest setting,and gradually narrowing the opening, almost every seed was dehulled. The stones crack the hulls open, then rub them to encourage the seed away from the fibrous lining. The Bell hand mill worked almost as well. "As long as the stones open at least as wide as the widest unhulled seed, any mill will work," she says.Because the seed slips through the mill on its flat side, grading is an important step to take before dehulling. We made three sizing boxes. Thefirst is 1/4-inch hardware cloth [wire screen]. The second is two layers of1/4-inch cloth, moved slightly apart to narrow the opening in one direction, and the third is two layers of screen adjusted to make a still-smaller opening. Since the smallest unhulled seeds are about the size of the largest hulled kernels, the grading step prevents these undersized seeds from passing through unhulled. Processed together at a closer setting, the smallest seeds hulled out.Jim Eldon's workshop is littered with strange-looking pieces of apparatus. They represent initial attempts to build a workable winnowing box, using Kormier's vacuum exhaust idea for a source of air. Jim, Fred Matlack and Diana finally made a box with a Plexiglas front, through which they could observe what was happening.They cut a hole in the back of the box with a sliding cover to regulate the air pressure, and fiddled with various arrangements of baffles. The result was a stream of hulls exiting through one hole while the kernels fell to the bottom of the box. Now they were ready to try a five-pound sample of unhulled sunflower seeds to see how much they could recover.The five pounds were graded and dehulled, then winnowed. We got about one hull for every ten kernels in the final, winnowed product. These are easily picked out. They usually contain kernels still held behind the fibrous strings of the hull. Their weight prevents them from blowing out with the empty hulls. We found that bug-eaten seeds do blow away with the chaff, which was a bonus for cleanliness of the final product. Toss the hulls to the birds, who will find broken seeds among them.Starting with 80 ounces of unhulled seed, we ended up with 41-1/4 ounces of edible whole seeds, 1.8 ounces of damaged seeds suitable for animal feed, and 36.6 ounces of hulls. It took us about an hour. Notbad.Sunflower seeds store perfectly in the hulls, but they deteriorate more rapidly when shelled out. The grain mill dehuller and winnowing box give the gardener a way to have the freshest possible seeds for eating at all times of the year. With the construction of one more piece of equipment -- the oil press -- he can have absolutely fresh, unrefined, polyunsaturated sunflower oil for salads, mayonnaise and cooking.Most light, refined vegetable oils have been extracted using hexane, a form of naphtha. The oil is then heated to boil off the hexane. Lye is dumped into it. It's washed with steam, then heated to remove odors and taste before being laced with preservatives and stabilizers. It may feel oily in the mouth, but you might as well taste air. No so with fresh-made sunflower oil -- it's deliciously yet subtly nutty in flavor, adding unsurpassed flavor to salads.There's good reason to believe that sunflower oil may become the #1 vegetable oil in the U.S. in a few years. It's already #1 in health-conscious Europe. Corn oil has already caught on here for health reasons, and sunflower oil is so much better. Sunflower oil's 70 percent polyunsaturate is just under safflower, with corn oil bringing up the rear with 55 percent. And sunflowers yield 40 percent oil, soybeans only 20 percent.Our oil press isrelatively simple, but it must be welded together. Check the construction directions for details. The press consists of a welded tubular frame which accepts a three-ton hydraulic jack. You may already have one. If not, it can be purchased at most auto and hardware stores for about $16. A metal canister with holes drilled in its sides and one end welded shut holds the mashed sunflower seeds. A piston is inserted in the canister and then inverted and slipped over a pedestal on the frame. The jack is set in place, and the pressure gradually increased over half an hour. The oil drips from the sides of the canister into a tray -- the bottom of a plastic jug slipped over the pedestal works fine -- which empties the oil into a cup. You can filter the oil with a coffee filter to remove pieces of seed and other fine particles that would burn if the oil were used for cooking. If it's for salads or mayonnaise, there's no need to filter it.We first tried using "confectionary" sunflower seeds for oil. These are the regular eating kernels we're used to seeing. They give less than half as much oil as the oilseed types of sunflower. Although you can use confectionary types such as MAMMOTH RUS- SIAN for oil, don't expect to get more than an ounce and a half from a pound of seed. Oilseed produces three or more ounces of oil from a pound of seed and is well worth planting along with confectionary-type seeds. Oilseed has another big advantage -- to prepare it, you can put the whole, unhulled seed into a blender and whiz it until it forms a fine meal, while confectionary seeds must be dehulled first. The entire sequence of grading, dehulling and winnowing is avoided with oilseed.Oil types produce about a tenth of a pound of seed per head in commercial production. Gardeners, with their better soil and care, invariably do better than that. Our conservative estimate is that 1,280 plants will be enough for three gallons of oil. Spaced one foot apart in rows two feet apart, 1,280 oilseed plants will take a space 40-by-56 feet, or 80-by-28 if you want a more rectangular patch to face south.We worked in pound batches, since the canister just holds one pound of mash. After blending, we heated it to 170 degrees F. (77 deg C) by placing it in a 300-degree F. (149 deg C) oven and stirring it every five minutes for 20 minutes. Heating gets the oil flowing and doubles the yield of oil. In case you're wondering,"cold-pressed" oils sold commercially are also heated, and some are subjected to the entire chemical process. The term has no firm meaning within the industry, according to the literature we've surveyed.Heating does not change the structure of fats. It will not turn polyunsaturated fats into saturated fats. In fact, Dr. Donald R. Germann in his book, "TheAnti-Cancer Diet", says that "... an unsaturated fat must be heated to high temperatures -- above 425 degrees F. or 200 degrees C. -- at least 8 or 10 times before any shift toward saturation occurs..." Dean C. Fletcher, Ph.D., of the American Medical Association Department of Foods and Nutrition in Chicago, says, "It's true that either high temperature or repeated heatingdoes change the nature of some of the unsaturated oil molecules. (But) the flavor of the oil changes as these chemical changes occur, spoiling its taste. This effect is probably more profound than any of the physiological changes the altered oil might produce within the body."From 500 gm. of heated mash, we pressed 89 gm. of oil, 89 percent of the entire amount available and twice as much as we could press from unheated oil! The decision is up to you whether or not to heat the mash, but that extra 50 percent seems like an awful lot, especially when the whole technique is so labor intensive. The oil should be stored in the refrigerator, and it's probably best to use it within a month, since it has no preservatives. Mayonnaise made with such fresh oils should be kept refrigerated and used within two weeks. The leftover cake, still containing 50 percent of its oil, is a nutritious addition to your dishes, and makes excellent feed for animals or winter birds. Store the pressed cake in the freezer.We're talking then about a sunflower patch with two kinds of plants -- confectionary such as MAMMOTH RUSSIAN and oilseed such as PEREDOVIK. The oilseed plants should be grown 12 inches apart in rows two feet apart. Four average confectionary heads yield about a pound of unhulled seed. You'll need about 35 pounds of unhulled seed, or 140plants-worth, to yield 20 pounds of hulled kernels, about what a family of four will use in a year. That many plants can be grown in an area 26-by-10 feet. That's 260 square feet. Put that together with the 2,240 square feet for the oilseed sunflowers, and you need a patch about 2,500 square feet -- 25 100-foot rows -- to keep yourself supplied year-round with super nutrition and unsurpassable taste.Winnowing Machine For Sunflower SeedsThe winnowing machine operates on the age-old principle of blowing the chaff away from the heavy grain with a controlled current of air.The unit uses a household or shop-type vacuum cleaner for its air supply. A vacuum cleaner was used as a power source because it can supply a large volume of air over an extended period of time, and most homes and farms have a vacuum cleaner.A cloth bag has been attached to the chaff chute to catch the chaff as it is separated from the seed. The bag allows the hulls to be collected and greatly reduces the amount of waste material normally blown into the air by conventional systems.The unit has been constructed in such a way that the cloth bag and cleaner box can be placed inside the seed box, making a compact package for storage.Tools Required1.

The oil can be pressed as is or heated to 170 degrees F., which doubles oil yield.Both methods require the seed to be ground to fine powder. If you are pressing the oil seed variety, a meat grinder or electric blender will do an excellent job of grinding the seed. The confectionary type of seed will require the seed to be hulled and winnowed before it is ground. A food mill with the stones set at the coarse setting can be used to accomplish this step. The ground kernels are placed in the cylinder with the piston closing the bottom portion of the cylinder.The cylinder is mounted in the press frame and a three-ton hydraulic jack is used to supply the pressure.Because of the great pressures created by the hydraulic jack, it is important that the frame be properly constructed and firmly mounted to the work surface before the pressing operation begins.

外文翻译资料外文原文：Washing machinesLet’s look inside one of today’s fully automatic washing machines that use swirling water to clean the clothes. There are many types of washing machines but this Figure shows you what most of them are basically made up of.。

The reason why a washing machine like this can wash and get the water out of the clothes at the same time is because it has a double layer drum.When1washing and rinsing,the pulsator spins and makes the water swirl..To get the water out of the clothes, the inner wall f the drum spins and the water goes through the holes.These days,the“centrifugal force washing machines”are quite popular.This type of machine does not use a pulsator.Instead,the inner wall spins really quickly.1外文翻译资料When the drum spins,the dirty clothes get stuck to the wall.The water and detergent also try to escape through the holes of the wall but before they do so,they are forced to escape through the clothes.When this happens,the power of the water and detergent removes the dirt form the clothes.Another good thing about this type of machine is that clothes don’t get tangled up so you don’t have to worry about your clothes getting ripped or damaged.Next,let’s look at some different types ofwashing machines!Many of you probably think that the water inside washing machines goes round and round. Actually, different washing machines make water flow in different ways.Whirlpool type:This type of washing machine uses a pulsator to force the water to move like a whirlpool inside the Drum.The spinning water forces the dirt out form the clothes inside the machine. Some of the newer models of this type also make the whirlpool move up and down to make it clean clothes even better!Agitator stirring typeThis type of washing machine has something that looks like a propeller at the bottom of the tub.This Propeller spins around and stirs the water.The water then forces the dirt out from the clothes in the machine.The good thing about this type of machine is that clothes do not get tangled up and clothes get evenly washed.Drum type:This type of machine has a drum with many holes in it. There are also protrusions bumps on the wall of the drum.As the drum turns,the clothes are picked up by the protrusions. When the clothes fall down from the top of the drum through the water,the movement removes dirt from the clothes.Centrifugal force type:2外文翻译资料As we have said before, the spinning drum pushes the water and detergent out through the wall of the inner drum. The power that comes form spinning the drum is called centrifugal force., which is where the name comes from. The water is forced through the clothes and then the holes in the inner wall.After one cycle,the water is recycled back into the tank and the process starts again.This cycle is what cleans the clothes!In Japan,people first started using machines in1930.But then the price of a washing machine was so high that most average persons could not buy one for their homes.Looking back now, there was something strange and funny on some of the first versions of the washing machine .The machine had two rollers that were used to sandwich each shirt and other clothes to squeeze the water out of them.The rollers were turned by hand,and in fact,you needed a lot of strength to turn those things!Still,people then thought it was a really neat invention!This type of water squeezer was used for almost 30 years until something new came along. The spin drier that used“centrifugal force”to get most ofthe water is out of the clothes.In1953,the nozzle type washing machine was first sold in Japan.This washing machine is like the older brother of the swirling washing machine that you see today. The price of these washing machines was lower and because of this, more people bought them. The first fully automatic washing machine was introduced in1968,and after that,washing clothes became a lot easier to do!There are a lot of different types of washing machines. What kind of washing machine do you have in your house?Fully automatic:The fully automatic machine has two drum layers that wash, rinse and removewater from clothes together. All you have to do is add detergent and put in dirty3外文翻译资料clothes and then washing machine will do the rest.There is also a new type of fully automatic washing machine that can dry clothes after they have been washed.Twin tub:This washing machine has one part that dose the washing and another part that does the squeezing.Even though it’s a hassle to take the clothes out and move them to other tub,the good thing is that you can wash and squeeze at the same time with one machine.Front loading:The main feature of front loaders is that they use a lot less water than other types.This is the type of Washing machine that dry cleaners use but a lot of people in western countries have this type of washing machine in their homes too.Let’s try to make the best washing machine in the world!We should already thank the scientists that invented the fully automatic washing machine because it makes washing clothes a piece of cake.Scientists are still trying really hard to find ways to make washing machines a lot handier to use for everyone.Some of the things that they are trying to do are to find better ways of making clothes clean and ways to make washing machines last longer.There are washing machines with d trying function today so you don’t even have to hang clothes after words because it dries them automatically!Amazing!Scientists are also trying to find ways to use less water and less detergent in washing machines at present.This is because that it is better to use less water for preserving the environment.What are washing machines of the future going to be like? Maybe there will be a washing machine that dries and folds your clothes after washing them,or maybe there will be one that will wash your clothes while you are still wearingthem! How handy would that be! Remember, if the first washing machine was like4外文翻译资料a dream to people in the old days, all the dreams you have about washing machines of the future may come true!Now, washing machine is becoming more and more popular. We see the main classification.Washing machine can be divided into automatic type and semi-automatic type two kinds, automatic type washing machine as long as we begin our work proactively set better washing procedure,washing machine began to work until the end without manual intervention. And semi-automatic washing machine washing and dewatering process is divided,is also called the double barrel washing machine, a tong,one takes off a bucket,and put tong inside washing out to artificial add to take off in the barrel dehydration is handled and complete laundry process.Full-automatic washing machine in structure to take off in tong internal bucket suit, two barrels of axis,while working with the clutch to finish washing state and dehydration of the transition of the states,on the key said is automatic washing machine.Full-automatic washing machine press catharsis means to points,can be dividedinto bunt washer and roll barrel type two kinds of washing machine, From the electric control ways to points,can be divided into mechanical program-controlled type and computer board controls type washing machine two kinds.The cylinder and the pulsator washing machine are now the main two kinds.Pulsator washing machine working principle is to add clothing,then open the inlet valve,choose good bibcock of water level and correct working procedures, switch on the power,closed warehouse door,and safety switch closed at water level,the public internal switch contacts are and dehydration contacts are interlinked,inlet valve electrify water,when the barrel water reaches the specifiedheight,in air pressure under the action of water level switch inside public contacts5外文翻译资料disconnect dehydration contacts and connect washing contacts,feed valve power to stop water,motor power is switched on,motor started running,and periodically sometimes are turning,sometimes reverse,mutual alternant,driven by clutch BoLun using the same cycle are turning,inversion,with a certain speed rotating BoLun can drive inside bucket of water and clothing,clothing rotating water formed in the mutual friction and reach the purpose of laundry. When washing process is completed,drainage electromagnetic valve electrify work,drain valve is opened,inside bucket of water exudes,and linkage shaft also the clutch from washing state switch to dehydration state,when drainage is completed,atmospheric pressure drop and inside bucket of water level switch public contacts reset through dehydration contacts,drainage electromagnetic valve keep electrify state,motor driven off running electrify bucket high-speed andjilt dry clothing,laundry program after washing machine disconnect hydropower and stop. As for intermediate process of how many times, laundry to wash the length of time, by process control.Roller-type washing machine of the principle and Pulsator washing machine are basic similar.But110mm drum machine it no clutch variable speed,but its motor is double-speed motor, so when washing machine work in washing state, program-controlled device connected motor washing low-speed windings, motor speed slow, working on dehydration, when they connect dehydration modal high-speed windings,motor high-speed operation,this process is programmed through the device and motor to work together to finish.To sum up, the role of these two kinds of washing machine is same, but different implementation,each has his strong point,Pulsator washing machine is simulated handmade kneaded action to work, 110mm drum type washing machine is by gravity inertial function to finish our work,they realize washing and6dewatering way also have different features,Pulsator washing machine to wear clothes is relatively large,but detergents degree is higher,110mm drum machine for clothing wear small,but detergents degrees,but lower than Pulsator washing machine to save water.So far,washing machine is still towards a higher requirements development.7译文：洗衣机来看一下涡流式全自动洗衣机的构造。

便携式洗衣机在旋转过程中的建模、设计和控制摘要：本篇主要介绍了水平轴式的便携式洗衣机简化的三维动态模型。

这个模型主要是用来预测洗衣机在旋转过程中移动不平稳的极限。

其次，还介绍了两种稳定的新方法。

一种是基于设计的方法，它减少了不稳定性并且发挥了有效作用；另一种是基于控制的方法，它消除了不稳定性和振动，与主动平衡有关。

这两种方法都顺应了时代的发展趋势，那就是朝着便携、轻型的全功能洗衣机方向发展。

I.介绍洗衣机的生产最近成了电器行业的一个重大问题。

当前的环保意识要求洗衣机的效率必须改进。

为此，以闭环——循环控制代替传统的开环——循环控制的方法被采用。

另外，尽管水平轴式的洗衣机有较高的生产成本，但因为它们已经证明比那些竖轴式的洗衣机消耗更少的能量、水和洗涤剂，所以变得越来越流行。

洗衣机重量的减少不仅对环境方面，对经济方面也是至关重要的。

但不幸的是，洗衣机仍然是大而重，质量常常都超过50千克。

这主要归因于在旋转过程中，衣物的不平衡转动。

这些旋转的衣物不均匀的分散在滚筒里，导致了显著的离心不平衡力，从而易于导致洗衣机的损坏。

这个问题，传统的解决方法是给系统加一个大的混凝土块，现在有三种模式：平移滑动、旋转滑动和翻转。

根据不同的旋转速度、衣物质量和系统的几何形状，任一种模式都可能成为最主要的破坏形式。

一个简化的二维动态模型曾经被用来证明了平移滑动和翻转的临界速度的存在，同时，它还表明竖轴式的洗衣机比水平轴的洗衣机稍微稳定些，但是，旋转滑动的问题仍然没有解决。

就稳定技术而言，研究主要集中在对悬置系统的利用。

更具体的说，关于悬置系统的分析和优化，专家已做了大量的工作。

另外，研究已经明确了移动和悬置系统之间有一定的关系。

另一项研究表明这个关系是可以很明确的。

自然，所有这些技术都将会改善洗衣机的动态性能，但是，除非机器的质量超过50千克，否则，这些技术还是不够的。

然而，很显然，这样的机器是不可能轻便的。

一个有趣的解决稳定的方法被Zuoxin提了出来。

洗衣机Washing machinesThe washing machine from invention to now bas experienced more than a century, through the following stages of development:The world’s first washing machine is the United States in 1874 by Bill Blackstonesuccessfully developed. Around 1910, a first horizontal shaft drum type electric washing machine, marking the housework automatic start. Nineteen twenties, the first vertical shaft stirring type washing machine to the United States of Americatrial-produceis successful, thewashingmachine, started the “vertical”and “horizontal”cent. The mid 50's, Japan’s Sanyo Company launched Dan Tongbo wheel type washing machine. Starts with the identification of a drum type, mixing type and the wave wheel three working modes. In 60, the Japanese launched with flings the dry barrel semi-automatic washing machine, and a large number of applications of plastic, so that the washing machine’s development into a new stage. In 70, the Japa nese launched a wave wheel sets of barrels of fully automatic washing machine, began washing machine concept. In the late 70, the Japanese launched a with “automatic”microcomputer controlled full automatic washing machine. Completed by the mechanical and electric program control computer control transition, started the computer control era. Then, the washing machine in the developed countries have entered the period of saturation, while in Asia Pacific developing countries began to enter the period of popularization. The late 80's,“fuzzy control washing machine”　began to appear, to achieve the home electric appliance control method on the high automation. “White goods”　concept. In 90’s, with the development of inverter technology, Japan launched the first of up motor direct driven washing machine washing machine driving mode, realized the revolution.The washing machine will be of high reliability，perfect function, water saving and power saving, time saving and noise reduction of specifications varieties diversification for the direction of development.The reason why a washing machine like this can wash and get the water out of the clothes at the same time is because it has a double layer drum. When washing and rinsing, the pulsator spins and makes the water swirl... To get the water out of the clothes, the inner wall of the drum spins and the water goes through the holes.are quite popular. This These days, the “centrifugal force washing machines”　type of machine does not use a pulsator. Instead, the inner wall spins really quickly.When the drum spins, the dirty clothes get stuck to the wall. The water and detergentalso try to escape through the holes of the wall but before they do so, they are forcedto escape through the clothes. When this happens, the power of the water and detergent removes the dirt form the clothes. Another good thing about this type ofmachine is that clothes don’t get tangled up so you don’t have to worry aboutyourclothes getting ripped or damaged.types of washing machines!Next, let’s look at some differentMany of you probably think that the water inside washing machines goes roundand round. Actually, different washing machines make water flow in different ways.Whirlpool type:This type of washing machine uses a pulsator to force the water to move like awhirlpool inside the Drum. The spinning water forces the dirt out form the clothesinside the machine. Some of the newer models of this type also make the whirlpoolmove up and down to make it clean clothes even better!Agitator stirring type:This type of washing machine has something that looks like a propeller at thebottom of the tub. This Propeller spins around and stirs the water. The water thenforces the dirt out from the clothes in the machine. The good thing about this type ofmachine is that clothes do not get tangled up and clothes get evenly washed.Drum type:This type of machine has a drum with many holes in it. There are also protrusions bumps on the wall of the drum. As the drum turns, the clothes are pickedup by the protrusions. When the clothes fall down from the top of the drum throughthe water, the movement removes dirt from the clothes.Centrifugal force type:As we have said before, the spinning drum pushes the water and detergent outthrough the wall of the inner drum. The power that comes from spinning the drum iscalled centrifugal force, which is where the name comes from. The water is forcedthrough the clothes and then the holes in the inner wall. After one cycle, the water isrecycled back into the tank and the process starts again. This cycle is what cleans theclothes!In Japan, people first started using machines in 1930. But then the price of awashing machine was so high that most average persons could not buy one for theirhomes.Looking back now, there was something strange and funny on some of the firstversions of the washing machine .The machine had two rollers that were used tosandwich each shirt and other clothes to squeeze the water out of them. The rollerswere turned by hand, and in fact, you needed a lot of strength to turn those things!Still, people then thought it was a really neat invention! This type of water squeezerwas used for almost 30 years until something new came along. The spin drier thatet most of the water is out of the clothes.used “centrifugal force” to gIn 1953, the nozzle type washing machine was first sold in Japan. This washingmachine is like the older brother of the swirling washing machine that you see today.The price of these washing machines was lower and because o f this, more peoplebought them. The first fully automatic washing machine was introduced in 1968, andafter that, washing clothes became a lot easier to do!There are a lot of different types of washing machines. What kind of washingmachine do you have in your house?Fully automatic:The fully automatic machine has two drum layers that wash, rinse and removewater from clothes together. All you have to do is add detergent and put in dirtyclothes and then washing machine will do the rest. There is also a new type of fullyautomatic washing machine that can dry clothes after they have been washed.Twin tub:This washing machine has one part that dose the washing and another part thatdoes the squeezing. Even though it’s a hassle to take the clothes out and move them to other tub, the good thing is that you can wash and squeeze at the same time with one machine.Front loading:The main feature of front loaders is that they use a lot less water than other types.This is the type of Washing machine that dry cleaners use but a lot of people inwestern countries have this type of washing machine in their homes too.Let’s try to make the best washing machine in the world!We should already thank the scientists that invented the fully automatic washingmachine because it makes washing clothes a piece of cake.Scientists are still trying really hard to find ways to make washing machines a lothandier to use for everyone. Some of the things that they are trying to do are to findbetter ways of making clothes clean and ways to make washing machines last longer.There are washing machines with drying function today so you don’t even have tohang clothes after words because it dries them automatically! Amazing!Scientists are also trying to find ways to use less water and less detergent in washing machines at present. This is because t hat it is better to use less water for preserving the environment.What are washing machines of the future going to be like? Maybe there will be a washing machine that dries and folds your clothes after washing them, or maybe there will be one that will wash your clothes while you are still wearing them! How handy would that be! Remember, if the first washing machine was like a dream to people in the old days, all the dreams you have about washing machines of the future may come true!Now, washing machine is becoming more and more popular. We see the main classification.Washing machine can be divided into automatic type and semi-automatic type two kinds, automatic type washing machine as long as we begin our work proactively set better washing procedure, washing machine began to work until the end without manual intervention. And semi-automatic washing machine washing and dewatering process is divided, is also called the double barrel washing machine, a tong, one takes off a bucket, and put tong inside washing out to artificial add to take off in the barrel dehydration is handled and complete laundry process. Full-automatic washing machine in structure to take off in tong internal bucket suit, two barrels of axis, while working with the clutch to finish washing state and dehydration of the transition of the states, on the key said is automatic washing machine.Full-automatic washing machine press catharsis means to points, can be divided into bunt washer and roll barrel type two kinds of washing machine, From the electric control ways to points, can be divided into mechanical program-controlled type and computer board controls type washing machine two kinds.The cylinder and the pulsator washing machine are now the main two kinds.Pulsator washing machine working principle is to add clothing, then open the inlet valve, choose good bibcock of water level and correct working procedures, switch on the power, closed warehouse door, and safety switch closed at water level, the public internal switch contacts are and dehydration contacts are interlinked, inlet valve electrify water, when the barrel water reaches the specified height, in air pressure under the action of water level switch inside public contacts disconnect dehydration contacts and connect washing contacts, feed valve power to stop water, motor power is switched on, motor started running, and periodically sometimes areturning, sometimes reverse, mutual alternant, driven by clutch BoLun using the same cycle are turning, inversion, with a certain speed rotating BoLun can drive inside bucket of water and clothing, clothing rotating water formed in the mutual friction and reach the purpose of laundry. When washing process is completed, drainage electromagnetic valve electrify work, drain valve is opened, inside bucket of water exudes, and linkage shaft also the clutch from washing state switch to dehydration state, when drainage is completed, atmospheric pressure d rop and inside bucket of water level switch public contacts reset through dehydration contacts, drainage electromagnetic valve keep electrify state, motor driven off running electrify bucket high-speed and jilt dry clothing, laundry program after washing machine disconnect hydropower and stop. As for intermediate process of how many times, laundry to wash the length of time, by process control.Roller-type washing machine of the principle and Pulsator washing machine are basic similar. But 110mm drum machine it no clutch variable speed, but its motor is double-speed motor, so when washing machine work in washing state, program-controlled device connected motor washing low-speed windings, motor speed slow, working on dehydration, when they connect dehydration modal high-speed windings, motor high-speed operation, this process is programmed through the device and motor to work together to finish.To sum up, the role of these two kinds of washing machine is same, but different implementation, each has his strong point, Pulsator washing machine is simulated handmade kneaded action to work, 110mm drum type washing machine is by gravity inertial function to finish our work, they realize washing and dewatering way also have different features, Pulsator washing machine to wear clothes is relatively large, but detergents d egree is higher, 110mm drum machine for clothing wear small, but detergents degrees, but lower than Pulsator washing machine to save water.So far, washing machine is still towards a higher requirements development.The world today is technology, knowledge explosion time, as long as the people have the need, it may produce some kind of product to meet the needs of the people. The development of washing machine is such, people found it some inconvenience in practice, will continue to improve and perfect it, new washing machine is born in this kind of situation.译文：洗衣机洗衣机从发明到现在已经经历了一个多世纪，经历了以下的发展阶段：世界上第一台洗衣机是于1874年由美国的比尔·布莱克斯通集团研制成功的。

中英文对照外文翻译洗衣机设计方案1. 引言本报告讨论了提高标准容量的家用洗衣机的能源效率的可行的设计方案。

在本设计方案分析中所使用的程序是基于由能源部（DOE）解释的规定，该规定概述了工艺改进措施。

根据合理的规则，不同的电器排名后，确定了潜在的设计方案，这在电器效率标准颁布的过程中又进了一步。

然后用筛选因子来确定是否应进一步考虑排除某一设计方案。

筛选设计方案中使用的很多输入程序都是由洗衣机制造商提供。

其他来源于贸易刊物和家用电器制造商协会（AHAM）。

虽然（在新工艺中）现有分析的设计方案阶段在规章制定预告（ANOPR）之前，与原ANOPR[2]相对应，但是以前从厂家收集到的数据，现有的AHAM的输入和其他利益相关者在这份报告中仍然会被考虑。

美国能源部打算在未来发出补充的法规制定提案预告。

2. 产品分类对消费者有使用价值的家电被纳入产品类的分析的行列。

类别是家电类型的一个子集，例如，洗衣机是一种家电，但是紧凑型洗衣机就是一种产品类别，家电产品根据不同的能源利用率被分成不同的类型。

能源部划分类别根据产品的容量或其他相关的性能特点，如产品的实用性和工作效率。

一般情况下，类的定义是通过从家电制造商，贸易协会和其他的相关的会议研讨中搜集的数据来做出划分。

那些已被指定的没有通过能源部测试程序的类的不再进一步分析。

目前，洗衣机的分类如表1所示，其中相应的最低能源能效要求自1994年5月14日起生效[3]。

表1 当前产品分类和效率标准产品分类效率标准紧凑顶级加载标准顶级加载半自动顶级加载前装加载肥皂水储蓄EF>=0.90ft/（千瓦时/圈）EF>=ft3/（千瓦时/圈）无冲洗加热无冲洗加热无冲洗加热在以前的规章制定中，顶级加载和前端转载分别被用来指垂直和水平轴洗衣机。

因为水平轴机器可以生产成顶级加载装置。

产品的等级差别——是基于衣服如何被加载而不是如何制作。

因此，垂直和水平轴洗衣机成了制造商的设计策略从而实现获得不同效率水平的洗衣机。

0 引言随着科学技术的不断进步，模糊控制技术正向各个领域渗透，在家用电器方面的应用也在迅速的发展，从而使家用电器向智能化方向迈进，以洗衣机为例，早期人们洗衣时用洗衣板，进而用机械定时式洗衣机，是半机械半电子式。

到后来是全自动洗衣机。

现在，人们希望的是智能型的洗衣机。

只要把衣服放进洗衣机，启动电源，洗衣机就能自动判别衣质、衣量、污浊度并自动确定洗涤时间，到最后出来的就是干净的衣服。

模糊型洗衣机应用了模糊控制技术，它和传统的洗衣机相比，是一种全新的家用电器。

它能自动识别布质、布量,自动识别脏污程度和脏污性质，自动决定进水量，自动投入恰当的洗涤剂，从而全部自动地完成整个洗涤过程。

由于洗涤程序是通过模糊推理而决定的，故能达到最佳的洗涤效果，从而大大提高了洗衣机的自动化程度和洗衣质量。

1概述1.1 意义及来源随着现代社会生活节奏的不断加快和人民生活水平的不断提高，人民对各种方便、快捷的家用电器需求量越来越大，洗衣机作为人民提高生活效率，追求生活质量的基本条件，也愈来愈成为不可或缺的生活用具。

在工业发达国家，洗衣机的普及率已经达到相当高的程度，但由于现阶段国情，洗衣机在我国的普及程度较低，农村更甚，随着生活质量的不断提高，人民对洗衣机的功能要求越来越高，使得洗衣机的更新较快，因此，洗衣机作为人民追求现代生活的一个基本要求在我国有着极大的市场。

洗衣机技术发展日新月异，产品类型众多，但从总体来看，人们对洗衣机的基本要求应是：省时、省水、省电，磨损率小，操作方便，功能完善等。

以上特点从技术的角度可由洗衣机的洗涤方式和控制方式这两个基本特性决定。

目前存在的洗涤方式有波轮式、搅拌式、滚筒式、喷流式、喷射式和超声波式等多种，在我国比较普及的洗涤方式是波轮式。

对洗衣机技术的发展使得人们期望在采用一种较洗涤方式的同时，希望洗衣机的控制部分能在洗涤过程中对衣物重量、胀度，洗涤剂的浓度，水的硬度、温度等影响洗涤效果的诸多因素进行检测，并能对这些检测结果做出合理的反应，从而得到比较理想的洗涤效果。

机械设计外文文献及翻译机械设计摘要：机器是由机械装置和其他组件组成的，用于转换或传递能量，例如发动机、涡轮机、车辆、起重机、印刷机、洗衣机、照相机和摄影机等。

许多原则和设计方法不仅适用于机器的设计，也适用于非机器的设计。

在机械工程和其他工程领域中，所有这些都需要机械设备，如开关、凸轮、阀门、船舶和搅拌机等。

关键词：设计流程、设计规则、机械设计设计流程在设计之前，应考虑机器的实际性，现有机器需要在耐用性、效率、重量、速度或成本方面得到改善。

新的机器必须具有以前机器所能执行的功能。

在设计的初始阶段，应允许设计人员充分发挥创造性，不受任何约束。

即使产生了许多不切实际的想法，也会在设计早期被改正。

只有这样，才不会阻碍创新思路。

通常还要提出几套设计方案，然后进行比较。

很可能在最终计划决定中，使用了某些不在计划之内的设想。

当外观特点和组件部分的尺寸特点分析透彻时，就可以全面设计和分析。

还要客观分析机器性能的优越性，以及其安全、重量、耐用性和成本竞争力。

每个至关重要的部分都要优化其比例和尺寸，同时也要保持与其他组成部分相协调。

还要选择原材料和处理原材料的方法。

通过力学原理来分析和实现这些重要特性，如静态反应的能量和摩擦力的最佳利用，动力惯性、加速动力和能量；包括弹性材料的强度、应力和刚度等材料的物理特性，以及流体润滑和驱动器的流体力学。

设计过程是重复和合作的过程，无论是正式还是非正式的，对设计者来说每个阶段都很重要。

最后，以图样为设计标准，并建立将来的模型。

如果测试符合要求，则对初步设计进行修改，以降低制造成本。

产品的设计需要不断探索和发展。

许多方案必须被研究、试验、完善，然后决定使用还是放弃。

虽然每个工程学问题的内容是独特的，但设计师可以按照类似的步骤来解决问题。

本文介绍了机械设计的复杂性和创造性，以及机械设计师所需要的基础知识。

在设计过程中，选择材料和进行精确计算都是必要的。

计算机辅助设计和制造技术已经成为现代机械设计的重要工具。

子母双筒洗衣机结构设计摘要现在，国内和国外的洗衣机分为很多类别，大致可分为波轮式洗衣机、滚筒式洗衣机、搅拌式洗衣机，从手动洗衣到自动洗衣，洗衣机经历了一次又一次的改进与更新，从节能型到智能型，洗衣机的更新换代见证了科技的发展。

当前，商场里的洗衣机种类各种各样，百花齐放。

但是有大小2个桶的洗衣机很少见，能将外套和内衣物分开同时洗的的洗衣机，基于以上考虑，提出了子母双筒洗衣机机构设计的课题，本文设计一种能将外衣物和内衣物分开洗的洗衣机。

本文主要研究洗衣机的机械结构，设计子母双筒结构，大桶的洗衣量为6kg，小桶的洗衣量为2kg，同时对洗衣机的动力传动进行计算和选型，本次毕业设计将对以后的工作有很大帮助。

子母双桶波轮洗衣机的设计设计者：彭勇志班级:南湖06级机自二班学号：24061900265 序号：60 引言目前国内外的洗衣机有很多种，波轮式洗衣机、滚筒式洗衣机、搅拌式洗衣机层出不穷，从手动洗衣机到自动洗衣机，洗衣机经历了一代又一代的变革与更新，从节能到智能洗衣机，这都是洗衣机的进步，尽管市面上的洗衣机种类繁多，可是却很少发觉能有大小2个桶，能将外衣服和内裤及其袜子分开同时洗的的洗衣机，于是，我感觉能够以此作为起点，设计一种能将外衣物和内裤及其袜子分开洗的洗衣机。

1 创新来源每次在自己洗衣服时，总感觉把内、袜子与其他衣物一路洗时总觉会将内裤和袜子上的很多细菌和赃物混淆到衣物上去，如此很容易引发各类潜在的疾病，尤其关于有传染病的人来讲，更是应当注意的地址，而一样的洗衣机都只有单一的一个洗衣的桶，若是分开做2次洗，即浪费水又浪费电，还要耗时刻，因此我假想能设计一种2个大小不同的桶，一个用来洗一般衣物，另外一个小的用来洗内裤或袜子。

2 创新题材洗衣机的进展历史1858年，一个叫汉密尔顿·史密斯的美国人在匹茨堡制成了世界上第一台洗衣机。

1874年,“手洗时期”受到了前所未有的挑战，美国人比尔·布莱克斯发明了木制手摇洗衣机。

1880年，又显现了蒸气洗衣机，蒸气动力开始取代人力。

1910年，美国的在试制成功世界上第一台电动洗衣机。

1932年，美国本德克斯航空公司宣布，他们研制成功第一台前装式滚筒洗衣机，洗涤、漂洗、脱水在同一个滚筒内完成。

1937年，第一台自动洗衣机于问世。

这是一种"前置"式自动洗衣机。

1955年，在引进喷流式洗衣机的基础之上，研制出独具风格、并流行至今的波轮式洗衣机。

至此，波轮式、滚筒式、搅拌式在洗衣机生产领域三分天下的局面初步形成。

60年代的日本显现了带干桶的双桶洗衣机，人们称之为“半自动型洗衣机”。

70年代，生产出波轮式套桶全自动洗衣机。

70年代后期，以电脑（事实上微处置器）操纵的全自动洗衣机在日本问世，开辟了洗衣机进展史的新时期。
