Description

Technical Field

[0001] The invention relates to a washing machine, in particular to a cleaning device for a washing tub wall of a fully automatic washing machine. Background Art

[0002] As a household appliance, washing machines have been widely used in households. For fully automatic washing machines (drum type and pulsator type) currently on the market, after one year of use, a layer of dirt will adhere to the inner wall of the water tub and the outer wall of the washing tub. As the use time increases, the adhered dirt will become thicker and thicker. The adhered dirt will cause mold when the washing machine is not used. The total bacteria in the washing machine exceeds the standard rate of 95.8%, the coliform group exceeds the standard rate of 37.5%, the fungus exceeds the standard rate of 45.8%, and the mold exceeds the standard rate of 60%. Some pathogenic bacteria such as Pseudomonas aeruginosa are also detected. If such washing machines are used to wash clothes, especially underwear, in the long run, various harms will be caused to the human body. However, the various detergents currently used to clean washing machines cannot clean the dirt on the wall of the washing tub. Now, they are all manually disassembled for cleaning. The washing tub is disassembled, cleaned with a brush, and then installed on the washing machine. Manual disassembly and cleaning operations require operators to undergo strict technical training and assessment before they can operate.

The rotating sleeve 11 is installed on the outside of the washing tub shaft 12. The rotating fixed frame 16 is provided with a longitudinal brush fixing tube 3 parallel to the axis of the washing tub and a transverse brush fixing tube 8 parallel to the bottom plane of the washing tub. The brush fixing tube is provided with radial brushes 4. The brushes 4 are symmetrically distributed on both sides of the longitudinal brush fixing tube 3 and the transverse brush fixing tube 8 and are closely arranged. Tube cores 20 are respectively arranged in the longitudinal brush fixing tube 3 and the transverse brush fixing tube 8, and a plurality of rubber return rings 19 are arranged between the tube core 20 and the brush fixing tube. The rotating fixed frame 16 is provided with an upper brush tube support seat 2, a corner brush tube support seat 6 and a central brush tube support seat 10 for supporting the brush fixing tube. The longitudinal brush fixing tube 3 is installed between the upper brush tube support seat 2 and the corner brush tube support seat 6. The transverse brush fixing tube 8 is installed between the corner brush tube support seat 6 and the central brush tube support seat 10. The longitudinal brush fixing tube 3 and the transverse brush fixing tube 8 can also be set in multiple groups and evenly distributed on the circumference and bottom surface between the washing tub 5 and the water tub 1. The intersection ends of the longitudinal brush fixing tube 3 and the transverse brush fixing tube 8 are respectively provided with bevel gears 7 that mesh with each other. The rotating shaft sleeve 11 is provided with an end face gear 14, and the transverse brush fixing tube 8 is provided with a cylindrical gear 13 that meshes with the end face gear. The inner end face of the cylindrical gear 13 is provided with two symmetrical positioning blocks 18, and two limit blocks 17 are provided at the corresponding positions of the central brush tube support seat 10. A cleaning brush driving motor 9 is provided below the water holding tub 1, and the cleaning brush driving motor 9 provides power to the rotating sleeve 11 through a belt drive. The washing tub 5 is provided with a barrel-shaped frame 15, and a barrel body with water permeable holes is provided on the frame 15, and the barrel body is composed of a plurality of arc-shaped barrel sheets 21, and the barrel sheets 21 are fixed to the frame 15 with screws to form the washing tub 5. The barrel sheets 21 and the frame 15 can also be fixed by permanent strong magnets to form the washing tub. The washing tub 5 adopts this split structure, which can be more convenient to repair and clean.

[0025] Figure 7 When the brush 4 is in working state, the rubber return ring 19 in the longitudinal brush fixing tube 3 is in a stretched state. Figure 8 It is the non-working state position of the rubber return ring 19 after the brush 4 returns.

[0026] When it is necessary to clean the inner wall of the washing tub of the washing machine, select the cleaning key on the washing machine. The cleaning brush driving motor 9 drives the rotating shaft sleeve 11 to rotate. The cylindrical gear 13 is rotated by the end face gear 14, and the transverse brush fixing tube 8 and the longitudinal brush fixing tube 3 rotate simultaneously. When the positioning block 18 rotates to the position of the limit block 17, the transverse brush fixing tube 8 and the longitudinal brush fixing tube 3 stop rotating. At this time, the brush 4 is in a state perpendicular to the inner wall of the washing tub, that is, the working state. The rubber return rings 19 in the transverse brush fixing tube 8 and the longitudinal brush fixing tube 3 are also stretched. And the end face gear 14 continues to rotate, so the rotating fixing frame 16 begins to rotate around the axis of the washing machine, and the brush 4 begins to brush the inner wall of the washing machine and the outer wall of the water storage tub. After the cleaning is completed, the cleaning brush driving motor 9 stops rotating, and the rotating fixing frame 16 also stops rotating accordingly. At this time, the rubber return rings 19 in the longitudinal brush fixing tube 3 and the transverse brush fixing tube 8 pull the brush 4 back to the non-working state, that is, the brush 4 is in a parallel state with the inner wall of the washing tub. Due to the stop rotation of the end face gear 14, the rubber return ring 19 has to pull the brush 4 back to its original position, and the cylindrical gear 13 rotates in the reverse direction. At this time, the rotating fixing frame 16 rotates in the reverse direction by a certain angle and then stops, completing the work of cleaning the washing machine.
