Problems solved by technology

[0005] (1) After the washing water is heated to the set temperature by using the first constant pressure heating method above, the temperature of the washing water will gradually decrease with the washing time, especially when the external temperature is low, the washing temperature will drop faster, The activity of the detergent needs to be stabilized in a small temperature range to exert the best decontamination effect, which will gradually reduce the activity of the detergent, and finally lose its activity, thus affecting the washing effect
[0006] (2) When the above-mentioned second constant pressure heating method is used to circulate and heat the washing water, the electric heater will be turned on and off frequently, which wastes electricity; and the controlled temperature range is large, and it is difficult to stabilize the temperature at the optimum value for the detergent. within the optimum temperature range

Abstract

The invention discloses a heating method and device and a washing machine. According to the main technical scheme, the heating method is applied to heating of wash water of the washing machine and comprises the steps of electrically heating wash water to a set temperature T under a set voltage; conducting voltage-reduction heating on wash water, wherein during voltage-reduction heating, electrical heating voltage is reduced continuously at a set rate; detecting the temperature of wash water in real time, and determining whether to continue to conduct voltage-reduction heating or stop heating or conduct constant-pressure heating according to the temperature of wash water so as to keep the temperature of wash water within T+ / -T0. A washing agent can be heated by the heating device and the washing machine by means of the heating method. The heating method and device and the washing machine are mainly used for keeping the temperature of wash water in the washing machine within the optimum temperature range which is suitable for the washing agent.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a heating method for heating washing water, a heating device and a washing machine. Background technique [0002] Washing machine is one of household appliances more commonly used in people's daily life. The use of washing machine brings convenience to people's life. But, along with the continuous improvement of people's quality of life, people also more and more higher to the requirement of washing effect of washing machine. The existing drum washing machine can heat the washing water when washing the clothes, which can fully stimulate the enzyme activity in the detergent, thereby improving the washing effect. At the same time, heating the washing water can also kill the bacteria carried in the clothes, and is widely used by users use. [0003] The drum washing machines in the prior art all adopt the constant pressure heating method to heat the washing water. Among them, the...
