Embodiment Construction

[0025] Specific embodiments of the present invention are described in detail below.

[0026] The laundry capacity control method of the washing machine of the present invention accurately samples the voltage and current network loaded on the DC motor when the washing machine is in operation, detects the running speed of the motor, and calculates the counter electromotive force to obtain the counter electromotive force and armature current of the DC motor The product, so as to obtain the average output power P of the DC motor, establish the corresponding relationship between it and the load weight of the clothes, and then obtain the weight of the clothes, and calculate the water intake, water intake time, and washing time according to the weight of the clothes obtained.

[0027] The method for controlling the clothes volume of the washing machine and the washing machine using the method will be described in detail below.

[0028] A method for automatically weighing clothes in a...

Abstract

The invention relates to a washing machine and a method for weighing clothes of the washing machine. The method comprises the following steps: controlling the running state of a direct current motor by using a main control panel of the washing machine; calculating the average output power P of the direct current motor according to the armature current which is detected and filtered by a current detection circuit and the actual motor rotating speed which is detected and filtered by a rotating speed detection circuit; and calculating to obtain the weight of clothes, calculating the washing time, the washing dynamics, the using amount of washing water and the water inlet time according to the obtained clothes weight, and washing according to the calculated parameters. The corresponding relationship between the washing machine and the clothes weight is established by calculating the average output power P of the direct current motor, so that the clothes can be weighed more accurately. The invention can realize the function of accurately weighing the clothes and improves the performance of the washing machine.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine and a method for weighing clothes. Background technique [0002] In the washing process of washing machine products, there is a problem that the amount of laundry is unknown, and the amount of laundry has an important impact on washing time, water intake time, water intake, and washing cycle. Therefore, it is generally necessary to determine the amount of laundry before washing. At present, there are mainly two methods for detecting the amount of laundry. One method is to detect the change of the back electromotive force of the single-phase motor and establish the corresponding relationship between the back electromotive force and the weight of the clothes. The difference in the placement of clothes will lead to poor detection accuracy. Another method is to open-loop adjust the speed of the motor to detect the size of the clothes through spe...
