Electricity use control and monitoring method of washing machine

Abstract

The invention discloses an electricity use control and monitoring method of a washing machine. The electricity use control and monitoring method comprises the following steps of executing a washing program by the washing machine, and detecting a clothing load amount m; after the washing machine finishes washing, obtaining the working time t1 of a motor; calculating the electricity consumption of the washing machine by the washing machine according to a formula of that W is equal to tha sum of the Wmotor and W0, wherein Wmotor is equal to k*P1*t1; k is a correction coefficient; k is in direct proportion to m; P1 is the rated power of the motor; W0 is the preset value of an electric component of the washing machine. According to the monitoring, by the electricity use control and monitoring method, of the electricity consumption of the washing machine, the monitoring is carried out mainly aiming at the electricity consumption of the main working device-motor in a washing process; by combining the characteristic of the washing process of the washing machine, a formula of calculating the electricity consumption of the motor is given out; in consideration of a main factor influencing theworking of the motor, the formula is corrected, so as to obtain a more accurate calculation result; therefore, an electricity consumption calculation method of the electricity use control and monitoring method is more accurate for the calculation result of the electricity consumption of the motor and the calculation of the electricity consumption of the washing machine is fundamentally ensured tobe in an error-tolerant range.

Description

technical field [0001] The invention belongs to the field of laundry, and in particular relates to a method for controlling and monitoring electricity consumption of a washing machine. 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 to detect the power consumption of the washing machine throu...

Problems solved by technology

[0005] (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

[0006] (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
