Abstract

The invention discloses a water level measurement system for a washing machine. The measurement system comprises a spinning device, a detecting device, and a main controller. The spinning device is arranged on the inner cover of the washing machine and has the same axle with a washing barrel of the washing machine. The detecting device is arranged on the spinning device and is used for detecting the distance between the detecting device and surfaces of contained objects inside the washing barrel and obtaining spacing values when receiving a water level detecting order. The main controller is used for determining whether the water level of the washing machine reaches a required level on the basis of a preset error detection value and the feedback spacing values from the detecting device; if the water level of the washing machine reaches the required level, a controlled water feeding switch is controlled by the main controller to stop feeding water. The invention also discloses a water level measurement method for a washing machine. By use of the water level measurement system and method for a washing machine, water level in a washing machine is accurately controlled, water resource is saved, clothing is ensured being washed clean, and the service life of a washing machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of water level measurement, in particular to a washing machine water level measurement system and method. Background technique [0002] The basic principle of the existing fully automatic washing machine to measure the amount of automatic water injection is: when the washing machine is started, it will idle for a few laps in the absence of water at first, because the clothes of different weights in the washing bucket of the washing machine have different loads on the motor of the washing machine, so the motor works The current of the washing machine is also different. According to the detected working current of the motor, the washing machine converts the weight of the clothes in the washing tub through calculations, and then determines the water level that needs to be filled according to the converted weight of the clothes, and performs automatic water filling. However, the benchmark of the above-mentioned ...
