Washing machine and drying judging method and device thereof

Abstract

The invention discloses a drying determination method and device for a washing machine and a washing machine, wherein the method comprises: before the washing machine enters the washing mode, weighing the clothes in the barrel of the washing machine to obtain the first weighing of the clothes in the barrel. After the washing machine enters the drying mode, the change value of the temperature inside the barrel of the washing machine is detected in real time; when the change value of the temperature inside the barrel is greater than or equal to the first preset threshold, the washing machine is controlled to continue to run in the drying mode for a preset time; After the preset time is run, it is determined whether the current value of the temperature change in the bucket is greater than or equal to a second preset threshold; if not, the motor in the bucket is weighed to obtain a second weighing value of the laundry in the bucket. Determining whether the second weighing value is less than or equal to the first weighing value; and if so, determining that the laundry in the tub is in a dry state, and controlling the washing machine to exit the drying mode. The method uses a combination of temperature determination and motor weighing determination to improve the accuracy of the determination.

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.

[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.
