Washing machine drainage control method and washing machine

Abstract

The invention discloses a washing machine drainage control method and a washing machine. The washing machine comprises a washing barrel and a water pan communicated with a drainage port of the washingbarrel. In the drainage control method, the washing machine controls the drainage process according to the water amount and / or load in the washing barrel, so that water drained out of the washing barrel is always lower than the safe water level of the water pan. According to the drainage control method, the water amount and / or the load in the washing barrel are / is obtained, the opening and closing frequency, the opening time and other drainage parameters of the drainage port in the drainage process are adjusted accordingly, the drained water is prevented from overflowing from the water pan, and the method is simple in logic, easy to implement and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of clothes treatment, and in particular relates to a washing machine drainage control method and the washing machine. Background technique [0002] Existing traditional washing machines often adopt the structure of inner and outer barrels. When draining, the water level in the inner and outer barrels drops simultaneously after the drain valve is opened until all the water in the inner and outer barrels is drained. In order to reduce the space occupied by the washing machine, the washing machine without an outer tub developed has a non-porous inner tub, and the original outer tub is provided with a water tray with a depth much smaller than that of the inner tub. During the drainage process, if the drainage sequence of the traditional washing machine is followed, the depth difference between the inner tub and the water receiving tray is relatively large, causing the drainage to overflow the water receiving tra...

AI Technical Summary

Problems solved by technology

During the drainage process, if the drainage sequence of the traditional washing machine is followed, the depth difference between the inner tub and the water receiving tray is relatively large, causing the drainage to overflow the water receiving tray, causing inconvenience to the user

[0003] In order to solve this problem, some manufacturers adopt the scheme that the inner tub and the water tray share the same drainage pipeline, and set a valve at the intersection, so that the washing machine without outer tub originally designed to reduce the size increases the shaft due to this special mechanical structure. to the size, which is not conducive to implementing

Some schemes adjust the drainage process by detecting the water level of the water receiving tray in real time. This scheme increases the number of detectors, increases the complexity of the washing machine control logic, and increases the cost.
