Drum cleaning program control method for full automatic washing machine

Abstract

The invention discloses a method for controlling the cleaning procedure of an automatic washing machine drum, which is characterized in that drainage is begun after completion of final rinsing until the water level in a monitoring outer drum of a water level controller of a signal detection circuit reaches a first set water level; a computer programmed controller controls a drainage valve to close, and drainage stops; the computer programmed controller controls a motor to be electrified, and an inner drum rotates until a time controller of the computer programmed controller detects a first set time; the computer programmed controller controls the motor to be power-down, and the inner drum rotates freely until the time controller of the computer programmed controller detects a second set time; the computer programmed controller controls the drainage valve to open, and drainage begins until the water level in the monitoring outer drum of the water level controller of the signal detection circuit reaches a second set water level; and normal dehydration procedure is performed. The control method which changes rinsing, drainage and dehydration cleans the outside of the inner drum and the inside and the bottom surface of the outer drum of an automatic washing machine, removes residual soil, and maintains a clean internal environment for washing clothes.

Description

technical field

[0001] The invention relates to a control method of a fully automatic washing machine, in particular to a program control method for cleaning the outer wall of the inner tub, the inner wall and the inner bottom of the outer tub. Background technique

[0002] Generally, the fully automatic washing machine starts to drain after the last rinsing, and directly enters the normal dehydration program after completely draining; during this draining process, the inner tub with water does not rotate. There are residual dirt on the outside of the inner tub of the automatic washing machine and the inside and bottom of the outer tub. If the above-mentioned normal anhydrous dehydration process does not clean those parts, bacteria will grow. Chinese patent application 03130180.0 discloses a washing machine with a washing tub cleaning function and a washing tub cleaning method. The water supply nozzle capable of spraying water evenly to the inner wall of the washing bucket ...
