Washing control method of full-automatic impeller washing machine

Abstract

The invention discloses a washing control method of a full-automatic impeller washing machine. The method comprises the following steps that: a, a computer program controller judges whether the work is a drainage work; if the work is not a drainage work, the process is over; otherwise, the step b is executed; b, in the drainage work, a water level sensor detects the water level; if the water level is equal to or lower than the no-water level, the process is over; and if the water level is higher than the no-water level, the step c is executed; c, the computer program controller controls to open a drainage valve to start drainage; and d, the computer program controller controls a motor to rotate so as to drive an inner drum to rotate according to the water level, and continuously increases the rotation speed of the inner drum along with the drop of the water level until the water level is equal to or lower than the no-water level. According to the invention, particles in the suspension can hardly attach to the drum wall, and thus the dirt accumulation is eliminated; and the motor speed is controlled, and the output of the motor is controlled below the rated power so as to improve the mechanical properties and the safety coefficient.

Description

【Technical field】 [0001] The invention relates to a washing machine, in particular to a washing control method for a fully automatic top-wheel washing machine, more specifically, a control method for effectively washing clothes and cleaning the washing environment. 【Background technique】 [0002] Modern washing machines use motors to drive the pulsator at the bottom of the washing tub to alternately rotate clockwise and counterclockwise to drive the clothes to tumble and rotate, so that the clothes and clothes, clothes and pulsator, clothes and the barrel rub against each other to achieve the purpose of washing clothes. [0003] When doing laundry, the water contains various solid particles, such as: scale formed by calcium ions and calcium carbonate in water, free matter in laundry detergent soap, lint from washed clothes, and particles left by the human body on the clothes to be washed. Oily proteins and various organic residues, bacteria and other substances introduced by...

Problems solved by technology

[0007] 2. When draining water, when the water level drops from the first set water level to the second set water level, the barrel is still, and the dirt in the sewage can still adhere to the wall of the barrel, and the cleaning is not thorough

[0008] 3. This method can only roughly control the rotation speed of the bucket by controlling the power-on time of the motor, and cannot provide a stable rotation speed and constant impact force, so it is difficult to guarantee the cleaning effect of the bucket

[0009] 4. It is difficult to grasp the first setting time and the second setting time of this method

If the first setting time is too long, it will easily cause water to splash and wet the ground; if it is too short, the cleaning effect of the bucket will not be achieved

If the second setting time is too long, electricity will be wasted; if it is too short, braking will be forced, which will damage the mechanical performance

[0011] 1. When the drainage speed is very slow such as the drainage pipe is blocked, the time required for the water level to reach the second set water level is uncertain, and the motor is continuously powered on during the period, which will easily cause the motor to overheat and cause a safety accident

[0012] 2. Step c of this method is unreasonable
