Washing machine and drying judging method and device thereof

Abstract

The invention discloses a washing machine drying determination method, device and a washing machine; the method comprises the following steps: when the washing machine enters a washing mode, motor weighting is carried out for clothes in a washing machine barrel, thus obtaining a first weight value of the clothes in the barrel; when the washing machine enters a drying mode, temperature change value in the barrel of the washing machine is detected in real time; when the temperature change value in the barrel is bigger than or equal to a first preset threshold, the washing machine is controlled to operate in the drying mode for a preset time; after the preset operation time, determining whether the temperature change value in the barrel in the present time is bigger than or equal to a second preset threshold or not; if not, motor weighing is carried out for the clothes in the barrel, thus obtaining a second weighing value of the clothes in the barrel; determining whether the second weighting value is smaller than or equal to the first weighting value; if yes, then the clothes in the barrel is dried, and the washing machine is controlled to quit the drying mode. The method combines temperature determination with motor weighting determination, thus improving determining accuracy.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a drying judging method of a washing machine, a judging device and a washing machine with the judging device. Background technique [0002] Along with improving constantly of people's living standard and living demand, the washing machine with drying type is more and more subject to people's attention and liking. For example, during the rainy season in the south, the environment is often in a humid state, and the clothes after washing are not easy to dry. Therefore, people often choose a drum washer-dryer with a drying mode to wash clothes. When the user selects the washing + drying mode , after washing, the washing machine will enter a drying mode to dry the clothes in the washing machine tub. [0003] In the related art, the automatic drying program of the drum washer-dryer generally judges whether the clothes are dried according to the degree of drying...

AI Technical Summary

Problems solved by technology

[0004] However, there is a problem that in the actual drying process of the existing drum washer-dryer, it is often judged whether it is drying only by the temperature difference, which will lead to a relatively one-sided judgment result, resulting in an inaccurate judgment, which may lead to Clothes are not dried, or over-dried, etc.
