Washing machine and wet cloth weighing method and device thereof

Abstract

The invention discloses a washing machine and a wet cloth weighing method and device thereof, wherein the method comprises the following steps: after the washing machine enters the dehydration program, the dehydrating motor of the washing machine is controlled to start to increase the speed from zero speed; in the speed increasing stage of the dehydrating motor Obtaining a first total power required to drive the first lap of the inner tub of the washing machine during the process of increasing the first rotating speed to the second rotating speed; and obtaining the dehydrating motor at the second running speed of the washing machine dehydrating motor The second total power required to drive the inner tub of the washing machine to rotate the second lap during the steady running operation, and obtain the average torque fluctuation value of driving the inner tub to rotate during the stable operation of the dehydrating motor at the second rotational speed; A total power, a second total power, and an average torque fluctuation value are used to calculate the weight of the laundry in the inner tub. According to the method of the present invention, the wet cloth weight of the laundry can be easily and accurately obtained during the dehydration process.

Description

technical field [0001] The invention relates to the technical field of washing appliances, in particular to a wet cloth weighing method for a washing machine, a wet cloth weighing device for a washing machine and a washing machine. Background technique [0002] The current frequency converter pulsator washing machines basically have the function of weighing dry cloth, that is, the clothes are weighed before the washing starts, so as to intelligently set the washing water level and washing cycle, and use dry cloth to weigh the clothes after they are wet Running in the same way is easy to cause stalling, and it is impossible to distinguish the weight of the clothes, so there is no similar action in the dehydration stage. When the user selects single dehydration, because there is no weighing function, the washing machine does not have any load information, it is easy to have problems such as bucket collision, failure to start, and failure to reach the maximum speed. In severe c...

[0002] The current frequency converter pulsator washing machines basically have the function of weighing dry cloth, that is, the clothes are weighed before the washing starts, so as to intelligently set the washing water level and washing cycle, and use dry cloth to weigh the clothes after they are wet Running in the same way is easy to cause stalling, and it is impossible to distinguish the weight of the clothes, so there is no similar action in the dehydration stage

When the user selects single dehydration, because there is no weighing function, the washing machine does not have any load information, it is easy to have problems such as bucket collision, failure to start, and failure to reach the maximum speed. In severe cases, it will cause abnormal noise of the whole machine and dehydration displacement, affecting users to experience
