干衣机什么牌子好,十大品牌测评(上篇)近期,很多网友提起干衣机什么牌子好?因为天气在变凉,有些地方的阳光变得不给力,老百姓对干衣机的需求变得迫切。
据观察,相关机构也发布了干衣机十大品牌排行榜。
小编也仔细分析了其中的分析文章,总体上是比较严谨和认真的,但因为网友需求多样,也网友提出:能否做一个干衣机十大品牌测评。
小编特别邀请到相关权威机构,为众网友做了干衣机十大品牌测评。
干衣机什么牌子好,这个问题让专家测评来解答。
专家根据需要,特别筛选了五个消费者最喜欢的干衣机品牌,对它进行全方位的测评。
五个干衣机品牌:奥德尔干衣机、贝尔莱德干衣机、艾美特干衣机、康威奇干衣机、海尔干衣机。
八项指标:知名度、市场占有率、安全性能、易用性、效率、好评率、人性化设计、材料等级、一、知名度知名度是表示一个品牌被公众知道,了解的程度,社会影响的广度和深度,即是评价名气大小的客观尺度。
此处,是按专家评分法来测评知名度的。
在此项上,奥德尔干衣机排在榜首。
二、市场占有率市场份额(market shares )指一个企业的销售量(或销售额)在市场同类产品中所占的比重,直接反映企业所提供的商品和劳务对消费者和用户的满足程度,表明企业的商品在市场上所处的地位。
三、安全性能家用电器产品安规标准,是为了保证人身安全和使用环境不受任何危害而制定的,是家用电器产品在设计、制造时必须遵照执行的标准文件,严格执行标准中的各项规定,家用电器的安全就有了可靠保证。
贯彻实施这一系列国家标准,对提高产品质量及其安全性能将产生极大影响。
安全标准,分对使用者和对环境两部分。
五大品牌的安全性能测试如下:此项目是网购消费者最关注的一点,五个品牌的差距也在这项上体现出来了,奥德尔和贝尔莱德得分不相上下,而康威奇得分低了近20分。
从此项上,我们可以看出知名品牌在做产品上的差距。
“做产品,就是做良心”对于干衣机仍然是有效的武器。
四、易用性易用性是可用性的一个重要方面,指的是产品对用户来说意味着易于学习和使用、减轻记忆负担、使用的满意程度等。
