[0002] 洗衣机是人们日常生活中比较常用的家用电器之一。 [0002] washing machine is one of people's daily lives more commonly used household appliances. 洗衣机的使用,为人们的生活带来便利。 Washing machine use, bring convenience to people's lives. 但是,随着人们生活质量的不断提高,人们对洗衣机洗衣效果的要求也越来越高。 However, with the continuous improvement of quality of life, people on the effects of laundry washing machines have become more sophisticated. 现有的滚筒洗衣机由于在洗涤衣物时能对洗涤水进行加热,充分激发洗涤剂中酶的活性,从而提高洗涤效果,同时,加热洗涤水还能杀死衣服中携带的细菌,而被广大用户使用。 Since a conventional drum washing machine capable of washing laundry in the wash water is heated to fully stimulate the activity of the enzyme in the detergent, thereby enhancing the washing effect, while heating the washing water can kill bacteria carried in the clothes, while the majority of users use.

[0003] 现有技术中的滚筒洗衣机都采用定压加热的方法对洗涤水加热。 The drum washing machine [0003] the prior art method are constant pressure heating of the wash water is heated. 其中,定压加热方法主要通过以下两种方式实现,其中,第一种方式为:通过加热器将洗涤水一次性加热至设定温度(该设定温度指的是能充分激活酶活性的温度)后停止加热,然后一直进行洗涤程序。 Wherein the constant pressure heating method is mainly implemented in two ways, the first way is: heated to a temperature set by a heater disposable wash water (the setting temperature refers to a temperature sufficiently activating activity ) after heating was stopped, and then the program has been washed. 第二种方式为:设定一个温度差,根据所设定的温度差,循环进行定压加热。 The second way: setting a temperature difference, based on the set temperature difference, the heating cycle constant pressure.

[0004] 但是,本发明的发明人发现上述定压加热洗涤水的方法中至少存在如下问题: [0004] However, the present inventors found that the above-described method at least the following problems constant pressure heat the washing water:

[0005] (1)采用上述第一种定压加热方式将洗涤水加热至设定温度后,洗涤水的温度会随着洗涤时间逐渐降低,尤其是当外界温度较低时,洗涤温度下降的更快,而洗涤剂的活性需要稳定在一个很小的温度范围才会发挥最佳的去污效果,这样会使洗涤剂的活性逐渐降低,最后失去活性,从而影响洗涤效果。 [0005] (1) the above-described first constant-pressure heating wash water is heated to the set temperature, the temperature of the washing water will be gradually reduced as the washing time, especially when the outside temperature is low, the washing temperature drop faster, and the need to stabilize the activity of the detergent in a small temperature range will play the best stain removal, it would be gradually decreased detergent activity, the final loss of activity, thus affecting the washing effect.

[0006] (2)采用上述第二种定压加热方式对洗涤水循环加热时,这样会使电加热器频繁开停,浪费电量;而且控制的温度范围较大,很难使温度稳定在洗涤剂适合的最佳温度范围内。 [0006] (2) When the above-described second predetermined pressure heated washing water circulation heating, which causes frequent opening and stops the electric heater, a waste of electricity; and controlling a large temperature range, it is difficult to stabilize the temperature of the detergent suitable within the optimum temperature range.
