Full-automatic cleaning device for inner wall and outer wall of roller washing machine and washing machine self-cleaning method

Abstract

The invention relates to a full-automatic dead-corner-free cleaning system for inner and outer walls of a roller washing machine and a washing machine cleaning method. The self-cleaning system of the washing machine comprises a self-cleaning device which is independently arranged between the outer wall of an inner barrel and the inner wall of an outer barrel of the washing machine and used for cleaning the part between the outer wall of the inner barrel and the inner wall of the outer barrel of the washing machine. The automatic cleaning device is started to spray any position between the outer wall of the inner barrel and the inner wall of the outer barrel of the washing machine along with rotation of the washing machine roller, dirt between the outer wall of the inner barrel and the inner wall of the outer barrel is effectively cleaned, and the purpose of timely cleaning is achieved.

Description

Technical Field

[0001] The invention belongs to the field of self-cleaning of washing machines, and in particular relates to a fully automatic cleaning device for inner and outer walls of a drum washing machine and a self-cleaning method for the washing machine. Background Art

[0002] Existing washing machines will wash out various substances when washing clothes. These substances cannot be completely discharged with the water flow. After a long time of accumulation, the washing residues are mixed with hair and peelings and adhere to the inner and outer drums of the washing machine, the gaps of the washing machine, the outer wall of the inner drum and the inner wall of the outer drum, especially at the connection between the transmission and the drum, thereby affecting the cleanliness of the washing machine when washing clothes and forming cross infection. At present, the existing washing machines can only be cleaned by adding chemical detergents or disassembling them for cleaning, which shortens the life of the washing machine and cannot clean the dirt remaining in the washing machine in time or automatically. Summary of the invention

[0003] The present invention solves the shortcomings of existing washing machine cleaning technology by adding an independent cleaning device between the inner drum and the outer drum of the washing machine to achieve timely cleaning of all positions in the washing machine. One washing machine per family can meet the hygiene requirements of the whole family, avoid cross infection, and achieve real clean laundry. BRIEF DESCRIPTION OF THE DRAWINGS

[0004] Figure 1 This is the optimal position of the cleaning device in the washing machine of the present invention.

[0005] Figure 2 The following are the principle diagram and schematic diagram of the fully automatic cleaning device for a washing machine according to the present invention.

[0006] In the figure: ① washing machine outer drum; ② washing machine inner and outer drum cleaning device; ③ washing machine inner drum outer wall; ④ internal gear; ⑤ rotating hollow shaft; ⑥ external gear. DETAILED DESCRIPTION

[0007] Figure 2 During the cleaning of the outer wall of the inner drum of the washing machine, water flows from ⑤ into ② to generate a high-pressure water column, which completes the cleaning of the outer wall of the inner drum as the inner drum rotates.

[0008] Figure 2 During the cleaning, the inner wall of the outer drum of the washing machine is pushed forward by ④. After contacting ⑥, the inner drum starts to rotate. ② and ⑤ rotate with the inner drum. The high-pressure water column enters ② from ⑤ and sprays upward and obliquely to clean the inner wall of the outer drum of the washing machine in all directions. After cleaning, it returns to its original position.

Claims

1. A fully automatic cleaning system for the inner and outer walls of a washing machine, characterized in that: It comprises a self-cleaning device: the device is separately placed between the outer wall of the inner drum and the inner wall of the outer drum of the washing machine, and is used for cleaning the area between the outer wall of the inner drum and the inner wall of the outer drum of the washing machine. The device comprises a spray device. When the self-cleaning function of the washing machine is started, the self-cleaning device is started. When cleaning the outer wall of the inner drum, the device remains in a fixed position and starts to spray water directly and obliquely. As the inner drum of the washing machine rotates, the outer wall of the inner drum and associated positions are cleaned. When cleaning the inner wall of the outer drum, the cleaning device is pushed toward a gear reserved at the tail end of the inner drum of the washing machine through a mechanical device, merged with the inner drum, and starts to spray water directly and obliquely upwards. As the inner drum rotates, the device is driven to rotate, so as to clean the inner wall of the outer drum and associated positions.

2. The location of the fully automatic cleaning system device of the washing machine according to claim 1 (between the inner and outer tubs); the device is placed in a location including: All positions between the outer wall of the inner cylinder and the inner wall of the outer cylinder.

3. The working principle of the fully automatic cleaning system for a washing machine according to claim 1 is characterized in that: The motion trajectory and the spraying device include but are not limited to the number of nozzles, the spraying direction and the spraying shape.

4. The fully automatic cleaning system for washing machines according to claim 1 includes but is not limited to changes in the shape of the device, such as: changing from L-shaped to S-shaped or other shapes.

5. The fully automatic cleaning device for a washing machine according to claim 1, characterized in that The outer wall of the inner cylinder can be cleaned first, or the inner wall of the outer cylinder can be cleaned first, or the two can be done alternately.

6. The fully automatic cleaning device for a washing machine according to claim 1, characterized in that: It is also suitable for drum and pulsator washing machines.
