Description

Technical Field

[0001] The utility model relates to the technical field of washing machine clutches, and particularly to a brake wheel of a washing machine clutch with a multi-channel water throwing tank. Background Technique

[0002] The brake wheel of a multi-channel water throwing tank washing machine is a crucial component in a washing machine. It mainly consists of a brake drum, a brake leather ring, brake shoes, springs, and an adjusting mechanism, etc. The brake drum is usually made of metal, in the shape of a cylinder or a disc, and is connected to the motor output shaft. The brake leather ring is located on the inner wall of the brake drum, made of wear-resistant material, and is in frictional contact with the brake shoes. As the main transmitter of braking force, the brake shoes adjust the contact force with the brake leather ring through springs and an adjusting mechanism, thereby controlling the rotation speed of the inner tub of the washing machine. When the washing machine needs to perform a drying operation, the motor rotates at a high speed, and at the same time drives the brake wheel to rotate together. The brake shoes of the brake wheel will be affected by electromagnetic force and leave the brake leather ring. At this time, the brake wheel and the output shaft of the motor can rotate freely, and the inner tub of the washing machine can be dried at a high speed. When the washing machine needs to stop drying or slow down the rotation speed, the motor stops outputting force or reduces the output force. The brake shoes will be affected by the spring force and reattach to the brake leather ring, and the brake wheel is braked, thereby slowing down or stopping the rotation of the inner tub. However, at present, in the braking process of the clutch brake wheel, it mainly relies on electromagnetic force to drive the brake shoes to approach or move away from the brake leather ring, and the pressure and friction coefficient generated by the electromagnetic force are usually low, and it is difficult to generate sufficient braking force in a short time to quickly decelerate the high-speed rotation of the inner tub of the washing machine. Under the conditions of a large-capacity washing machine or high rotation speed requirements, insufficient braking force will lead to too long rotation time of the inner tub, affecting the user experience.

[0003] The purpose of the utility model is to provide a brake wheel of a washing machine clutch with a multi-channel water throwing tank. The hollow pipe seat and the air inlet pipe are connected to a booster pump, and the elastic pushing structure is forced to act through air pressure, so that the lower brake pad frictions and contacts with the brake wheel body, so as to solve the problems raised in the above background technique.

[0004] To achieve the above object, the present utility model provides the following technical solutions: A washing machine clutch brake wheel for a multi-channel water throwing tank includes a C-shaped card seat and a flat plate fixed to the top end of the C-shaped card seat.

An upper support ring is welded to the top wall of the C-shaped card seat, and a brake wheel body is rotatably installed at the bottom end of the upper support ring. A docking sleeve with a threaded hole is installed at the bottom end of the brake wheel body. One side of the top end of the right-angle seat is fixed with a hollow tube seat, and an elastic pushing structure is arranged inside the hollow tube seat. The movable end of the elastic pushing structure extends into the C-shaped card seat and is installed with a lower brake pad. An air inlet pipe is installed at the bottom end of the hollow tube seat.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A washing machine clutch brake wheel of a multi-channel water throwing sink, including a C-shaped card seat 1 and a flat plate 4 fixed to the top end of the C-shaped card seat 1, and a right-angle seat 5 is fixed to the bottom end of the flat plate 4. An upper support ring 2 is welded to the top wall of the C-shaped card seat 1, and a brake wheel body 3 is rotatably installed at the bottom end of the upper support ring 2. A docking sleeve 301 with a threaded hole is installed at the bottom end of the brake wheel body 3. The brake wheel body 3 is bolted to the flange on the outer peripheral surface of the dehydration shaft through the docking sleeve 301 and the threaded hole at the bottom end of the docking sleeve 301, so that the brake wheel body 3 and the dehydration shaft are stably connected. The flat plate 4 and the right-angle seat 5 are fixed to the inner wall of the washing machine housing. One side of the top end of the right-angle seat 5 is fixed with a hollow pipe seat 7, and an elastic push structure 11 is arranged inside the hollow pipe seat 7. The movable end of the elastic push structure 11 extends into the inside of the C-shaped card seat 1 and is installed with a lower brake pad 12. An air inlet pipe 8 is installed at the bottom end of the hollow pipe seat 7, an exhaust pipe 9 is installed on the outer wall of one side of the hollow pipe seat 7, and a solenoid valve 10 is installed at the top end of the exhaust pipe 9;

[0019] On the other side of the bottom end of the flat plate 4, an upper brake pad 6 is fixed;

[0020] The bottom end of the upper support ring 2 is provided with two annular grooves, and the top end of the brake wheel body 3 is integrally formed with two annular flanges for slidingly cooperating with the annular grooves. The annular flanges at the top end of the brake wheel body 3 and the annular grooves at the bottom end of the upper support ring 2 ensure the stability of the brake wheel body 3 and the dehydration shaft during the rotation and manufacturing process.

[0021] The outer circumferences of the air intake pipe 8 and the exhaust pipe 9 are both provided with thread grooves, which facilitate the connection of the air intake pipe 8 and the exhaust pipe 9 with the external pipeline and the valve body;

[0022] The elastic push structure 11 includes a push rod 1101 slidably installed at the center position of the hollow tube seat 7, a stopper 1103 integrally formed at the bottom end of the push rod 1101, and a stopper 1104 installed at one end of the surface of the push rod 1101. A coil spring 1102 is installed inside the hollow tube seat 7 above the stopper 1104. The outer diameter of the coil spring 1102 is equal to the inner diameter of the hollow tube seat 7. When the brake wheel body 3 needs to be braked, the staff connects the air intake pipe 8 to the booster pump through the air pipe. At this time, the booster pump blows air into the interior of the hollow tube seat 7. Then the air pressure under the stopper 1103 and the stopper plate 1104 increases, so that the stopper 1103, the stopper plate 1104 and the push rod 1101 are driven to move upward. Due to the existence of the stopper plate 1104, the spiral spring 1102 is squeezed and deformed, and then the push rod 1101 drives the lower brake pad 12 to move upward and contact the lower surface of the brake wheel body 3. During this process, the solenoid valve 10 is in a normally closed state. Compared with the possible electronic failure or mechanical wear of the electromagnetic brake structure, the air pressure driven brake system is less likely to have such problems, and the maintenance and care required are relatively less;

[0023] The coil spring 1102 is concentrically sleeved on the top rod 1101, and a sealing ring is inlaid on the outer peripheral surface of the baffle plate 1104, so as to improve the sealing performance of the chamber below the baffle plate 1104.

[0024] When the embodiment of the present application is in use, first, the dehydration shaft in the washing machine clutch of the multi-channel water throwing tank penetrates into the interior of the brake wheel body 3, and the brake wheel body 3 is connected to the dehydration shaft through the docking sleeve 301 with threaded holes. Subsequently, the staff connects the air inlet pipe 8 to the booster pump to utilize the booster pump to provide an air pressure source. The air pressure generated by the booster pump is transmitted to the elastic pushing structure 11 through the air inlet pipe 8 and the hollow pipe seat 7 to push it to act. Subsequently, the lower brake pad 12 applies a force to the brake wheel body 3, and the friction surface of the lower brake pad 12 contacts the surface of the brake wheel body 3. The rotation of the brake wheel body 3 and the dehydration shaft is slowed down or stopped by means of frictional braking, thereby controlling the movement of the inner barrel of the washing machine. When the braking contact occurs, the solenoid valve 10 actively releases the air pressure under the control of the washing machine control board, so that the solenoid valve 10 is in an open state. Subsequently, the interior of the hollow pipe seat 7 is depressurized, so that the elastic pushing structure 11 and the lower brake pad 12 are reset. By controlling the contact force of the lower brake pad 12 through air pressure, precise braking control can be achieved. Compared with the traditional friction braking system, the pneumatically driven braking structure can provide a more stable and controllable braking effect, enabling the washing machine to quickly and accurately stop or decelerate under various working conditions, and can meet the braking requirements of large-capacity washing machines or high rotational speeds.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
