Washing machine power consumption monitoring method, washing machine, and washing machine system

Abstract

The invention provides a washing machine power consumption monitoring method comprising the steps of executing washing program by a washing machine, and detecting a clothes load capacity m; obtaining working time t1 of a motor after clothes are washed by the washing machine; and computing washing machine power consumption by the washing machine according to the formula W=Wmotor+W0, wherein Wmotor=k*P1*t1, k is a correction factor and in direct proportional to m, P1 is rated power of the motor, and W0 is a preset value of an electrical element of the washing machine. For the washing machine power consumption monitoring, power consumption of the main working equipment-motor during the clothes washing process is monitored, combined with characteristics of the working process of the working machine, the formula for calculating the motor power consumption is provided, and the motor power consumption is corrected in view of main factors influencing the motor operation so as to obtain a more accurate calculating result. Accordingly, the calculating result of the motor power consumption is relatively accurate by using the power consumption calculating method, and calculation of the washing machine power consumption is thoroughly ensured to be within the range of errors permitted.

Description

technical field [0001] The invention relates to the technical field of washing machine water and power consumption detection, in particular to a washing machine power consumption monitoring method, a washing machine and a washing machine system. Background technique [0002] The existing drum washing machines and fully automatic washing machines do not have the detection of laundry power consumption. After the user uses a certain laundry program to wash, he cannot know the power consumption of this laundry. The user's understanding of the washing machine is still at the original level. In terms of washing time, washing program, washing water temperature, washing water level, etc., in order to help users understand the washing machine more deeply and cultivate users' power-saving habits, it is necessary to increase the washing power consumption detection of the washing machine. [0003] The traditional method of detecting the power consumption of the washing machine is mainly...

AI Technical Summary

Problems solved by technology

[0006] (1) From the above calculation formula of power consumption, it can be seen that the calculation of power consumption is related to the amount of water inflow, and the detection of water inflow is directly related to the accuracy of power consumption calculation. Therefore, the calculation accuracy of power consumption cannot be effectively obtained. guarantee

[0007] (2) In order to ensure the accuracy of water intake detection, a water intake detection device is required, which increases the manufacturing cost of the washing machine and is not conducive to market promotion
