Drum washing machine drying control method capable of reducing hydroelectric energy consumption

Abstract

The invention discloses a drum washing machine drying control method capable of reducing hydroelectric energy consumption. The drum washing machine drying control method comprises the following steps that a washing machine drying program is started, and the flow of a condensation valve of a washing machine is controlled to be 0.2-0.3 L / min; after the drying program is started for 30 min, the temperature T of a water heating pipe ntc is collected in real time, and the maximum value is selected from the collected temperature T of the water heating pipe ntc and recorded as Tmax; and the difference value T between the ntc temperature T of the water heating pipe and the maximum value Tmax is calculated in real time, and when the difference value T reaches a set value, it is judged that the clothes are dried at the moment, and a controller closes the drying program of the washing machine. By reducing the flow of the condensation valve, the use amount of condensate water in the drying process can be effectively reduced, and water is saved; relatively high environment temperature in a barrel can be produced by reducing the flow of the condensation valve, so that the drying efficiency is improved, and the drying time is shortened; and by shortening the drying time, the electricity consumption in the drying process is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of washing machine control, and in particular relates to a drying control method of a drum washing machine capable of reducing water and electricity energy consumption. Background technique [0002] At present, most of the drum washing machines with condensation drying function on the market work by blowing hot air into the bucket through the heating pipe of the drying tunnel, and then evaporate the moisture in the clothes into the hot air in the bucket to form hot and humid air; Then, the hot and humid air is brought to the condensing device through the circulating air in the barrel, and condensed water is formed after condensation, flows to the bottom of the barrel, and is finally discharged by the drainage pump, so as to achieve the effect of continuous drying. During this process, the heating tube will consume a lot of electricity, and the condensation device will continue to consume water. Some manufac...

Problems solved by technology

[0003] For the method of increasing the temperature range of the heating tube of the drying tunnel, although the drying efficiency can be improved to a certain extent, but the temperature range of the heating tube is increased, the working time of the heating tube is bound to be extended, and its power consumption will also increase simultaneously; The method of heating the temperature range of the tube, because the temperature range is lowered, the temperature in the barrel is correspondingly lower, the drying efficiency is reduced, the drying time will be extended to a certain extent, and the water consumption will increase. If the method is used to dry in advance and stop If the drying time is shortened, it is easy to cause the load to fail to dry
