在当前商品经济的大潮冲击下,家电产品生产厂家为使其产品占有竞争优势,不断改进产品性能,控制方式也由手动、半自动到全自动,这是家电产品发展的总趋势。 但是要想占有家用电器产品市场,必须做到运行可靠,功能多样,操作简单方便,价格低廉。达到上述目标并不是一件容易的事情。因为这几者之间存在着矛盾。功能强,控制参数多,装置就变得复杂,成本上升。操作上也会较为烦琐。可靠性相对降低。综合考虑之下,解决这些问题的最好办 Under the tide of the current commodity economy, the manufacturers of home appliance products keep their products competitive and continuously improve product performance. The control methods are also from manual to semi-automatic to fully automatic. This is the general trend of the development of home appliance products. However, in order to occupy the market of household appliances, we must achieve reliable operation, diverse functions, simple and convenient operation and low price. To achieve these goals is not an easy task. Because there is a contradiction between these few. Strong functions, many control parameters, the device becomes complicated, the cost increases. Operation will be more cumbersome. Relatively lower reliability. Taken together, the best solution to these problems
