Abstract

The invention discloses a method and device for weighing clothes in a washing machine, and relates to the technical field of washing machines. The method comprises the steps that when a motor rotates, the transient angle of flow of the motor is calculated; according to the transient angle of flow of the motor and a characteristic curve of motor power signals, transient power consumed by the motor is calculated; integral summation is carried out on the transient power consumed by the motor, and work of the motor on clothes is obtained; according to the corresponding relation of the magnitude of the work and the weights of clothes, the clothes weight corresponding to the work which is done to the clothes by the motor is searched for. The clothes in the washing machine can be weighed through software, extra hardware detection circuits are not needed, and product cost reduction is facilitated.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a method and device for weighing clothes in a washing machine. Background technique [0002] At present, the amount of clothes in the washing machine has a very important impact on the washing performance. If the washing machine can sense the weight of the clothes during the washing process, it can optimize the washing process to achieve the best washing performance. [0003] The existing technologies for sensing the weight of clothes are all based on a certain hardware environment. For example: adding a hardware detection circuit to detect the current or voltage fed back from the motor to the control board to calculate the weight of the clothes in the washing machine. [0004] However, increasing the hardware detection circuit will increase the cost of the product, and in addition, the difference of the whole machine system will affect the detection effect.
