Control system and control method of washing machine

Abstract

The invention relates to a control system and a control method of a washing machine. The control system comprises a locking and unlocking switch, a control unit, a locking and unlocking power device and a locking and unlocking device, wherein the locking and unlocking switch is used for inputting a signal for requesting to lock an inner barrel or a signal for requesting to unlock the inner barrel;the control unit collects one or several of signals or / and values for indicating whether the inner barrel of the washing machine works or not, and receives the signal for requesting to lock the innerbarrel or the signal for requesting to unlock the inner barrel; the locking and unlocking power device makes judgment according to the signal input by the locking and unlocking switch and the signalsand / or the values for indicating whether the inner barrel of the washing machine works or not; when a judging result shows that the inner barrel of the washing machine is in a safe state and a requirement of unlocking or locking the inner barrel exists, the locking and unlocking power device is started, and otherwise, the locking and unlocking power device cannot be started; and the locking and unlocking device is used for locking or unlocking the inner barrel of the washing machine, and uses the locking and unlocking power device for providing locking or unlocking power.

Description

technical field [0001] The invention relates to a washing machine, in particular to a control system and a control method of the washing machine. Background technique [0002] The types of washing machines include pulsator washing machines, drum washing machines, stirring washing machines, jet washing machines and the like. [0003] 1. The power of the pulsator washing machine is generally about 400 watts, and the power consumption is less than 0.5 kWh. The washing power of the drum washing machine is generally about 1200-2500 watts. In addition, when washing the drum washing machine, an electric heater is needed to raise the water temperature to achieve a better washing effect. If the water temperature is increased to 60 degrees Celsius, the power consumption is about 1.5 degrees. [0004] 2. The drum-type washing machines adopt water-saving technology that controls the amount of water, heating washing technology, rain, soaking, beating triple washing, three-dimensional wa...

AI Technical Summary

Problems solved by technology

[0005] 3. Stirring washing machines have the strongest cleaning power and save washing powder. Disadvantages: Compared with the previous two methods, the entanglement is more damaging and the noise is the loudest.

[0008] 1. Existing washing machines still have faint stains on clothes with serious pollution even after washing, which cannot achieve the effect of manual scrubbing

[0009] 2. When the existing drum washing machine is washing, the clothes are thrown to a high place by the drum and then fall back to a low place to cycle the clothes for washing. However, this movement mode does not make the clothes evenly rubbed with force, and the cleaning effect is limited.

[0010] 3. The existing washing machine cannot fully clean the washing powder under the condition of limited number of water changes, resulting in some washing powder remaining on the clothes

[0011] 4. After the washing machine has been used for a period of time, the appearance looks bright and new, but there are dirt and dirt in the space between the outer wall of the inner cylinder and the inner wall of the outer cylinder. These dirt contain harmful bacteria. If these dirt are not removed in time, it will cause damage to the washing machine. harm to human health

[0012] 5. When the inner cylinder and the outer cylinder are disassembled in the prior art, the inner cylinder needs to be positioned to ensure that the installation is in place when the inner cylinder is restored. However, in the prior art, the installation alignment is a troublesome task, and it is not easy to align and install at one time In place, need to try again and again

However, when the locking and unlocking device is unlocked, the inner cylinder and the outer cylinder can be separated. If the inner cylinder is still rotating at a high speed, it will be thrown out under the action of centrifugal force, which will seriously affect the safe use of the washing machine. Therefore, a control system must be provided to ensure Locking and Safe Use of Washing Machines
