Description

Technical Field

[0001] The utility model relates to the technical field of washing machine equipment, and more specifically, it relates to a noise reduction system and a noise reduction washing machine thereof. Background Technique

[0002] A washing machine is a cleaning appliance that uses electric energy to generate mechanical action to wash clothes. Generally, it specifically refers to a cleaning tool that uses water as the main cleaning liquid, which is different from a cleaning tool that uses a special cleaning solution and plays an important role in the development of mankind.

[0003] At present, the existing pulsator washing machine puts clothes into the inner container, and the control system controls the washing machine to work to wash and spin-dry the clothes in the inner container. However, since the pulsator washing machine needs to rotate the inner container for the dehydration process, when the rotation speed does not reach high speed rotation, the inner container will be eccentric and collide with the washing machine housing, thus generating abnormal noise, affecting the user experience, and the frequent collision of the inner container with the washing machine housing will shorten the service life of the inner container and cause economic losses.

[0004] Therefore, in order to solve the above technical problems, this application proposes a noise reduction system and a noise reduction washing machine thereof. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a noise reduction system and a noise reduction washing machine thereof.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A noise reduction system and a noise reduction washing machine thereof, including an inner container, a driving component is arranged inside the inner container, the driving component includes an execution motor for driving the inner container to work, a plurality of water leakage holes are opened on the outer side of the inner container, and a water outlet is opened at the bottom end of the inner container. A noise reduction component for effectively reducing the noise generated during the operation of the device is arranged on the outer side of the inner container. The noise reduction component includes a shock absorption cylinder, and a plurality of shock absorption springs for preventing the inner container from directly colliding with the washing machine housing to generate noise are arranged on the outer side of the shock absorption cylinder.

[0007] The driving component can drive the washing machine to wash clothes while eliminating noise. Through the noise reduction component, during the dehydration process of the washing machine, the inner container will not collide with the washing machine housing to generate abnormal noise, which maximally reduces the generation of noise and prevents the user from being troubled by noise when washing clothes.

[0008] Preferably, a receiving frame is fixedly installed at the upper end of the inner container, and the shock absorption cylinder is rotatably connected to the receiving frame. The receiving frame can provide an installation position for the shock absorption cylinder and ensure that the distance between the inner container and the shock absorption cylinder will never change.

[0009] Preferably, a sound-absorbing cotton for effectively reducing the noise generated by the rotation of the inner tank is fixedly installed on the outer side of the inner tank. The sound-absorbing cotton is provided with a plurality of through holes, and the positions of the water leakage holes correspond to the positions of the through holes, so that the sound-absorbing cotton does not interfere with the normal drainage of the water leakage holes.

[0010] Preferably, one end of a plurality of the shock-absorbing springs is fixedly connected to the outer side of the shock-absorbing cylinder, and the other end is fixedly connected to the washing machine housing. The telescopic elastic force of the shock-absorbing springs can reduce the shaking amplitude of the inner tank when dehydration occurs, thereby preventing the inner tank from coming into direct contact with the washing machine housing.

[0011] Preferably, the actuating motor is fixedly arranged at the bottom of the inner tank. A sound-insulating box is arranged outside the actuating motor. The output end of the actuating motor extends into the inner part of the inner tank and is provided with a partition board. A plurality of stirring rollers for stirring clothes are arranged at the upper end of the partition board.

[0012] Preferably, a sound-absorbing board for isolating the noise of the actuating motor is fixedly installed inside the sound-insulating box. The partition board is made of a sound-insulating material. The sound-absorbing board can absorb the noise generated when the actuating motor starts, and at the same time, the partition board can isolate the sound emitted by the actuating motor, further reducing the noise emitted by the washing machine.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the sound-absorbing cotton can effectively absorb the noise generated by the inner tank itself during rotation, and the shock-absorbing cylinder rotatably connected to the bearing bracket can keep a fixed distance from the inner tank. Then, the shock-absorbing springs fixedly connected to the washing machine housing ensure that the inner tank will not be eccentric during rotation, ensuring that the inner tank will not collide with the washing machine housing during dehydration and generate noise. On the one hand, the service life of the inner tank is prolonged, avoiding economic losses of users. On the other hand, the generation of collision noise is reduced, improving the use experience of users.

[0015] 2. In the utility model, by using the sound-absorbing board inside the sound-insulating box, the noise generated when the actuating motor operates can be absorbed by it, and the partition board is made of a sound-insulating material, so that the noise generated by the actuating motor during stirring of the washing machine can be isolated in the sound-insulating box and will not be transmitted to the inside of the washing machine through the vibration generated by the stirring of the stirring rollers and emit noise, further improving the sound insulation and noise reduction effect of the washing machine and improving the practicability of the device.

[0022] As Figures 1-4 shown, the present utility model provides a noise reduction system and a noise reduction washing machine thereof, including an inner container 1. A plurality of water leakage holes 101 are opened on the outer side of the inner container 1. When dehydrating, waste water can flow out from the water leakage holes 101 by using the water leakage holes 101, and a water outlet 103 is opened at the bottom end of the inner container 1. Through the water outlet 103, the washing machine can drain water normally. A noise reduction component 2 for effectively reducing the noise generated due to the operation of the device is arranged on the outer side of the inner container 1. The noise reduction component 2 includes a shock absorption cylinder 201, and a plurality of shock absorption springs 203 for preventing the inner container 1 from directly colliding with the washing machine shell to generate noise are arranged on the outer side of the shock absorption cylinder 201;

[0023] A bearing frame 202 is fixedly installed at the upper end of the inner container 1. The shock absorption cylinder 201 is rotatably connected with the bearing frame 202. Sound absorption cotton 102 for effectively reducing the noise generated by the rotation of the inner container 1 is fixedly installed on the outer side of the inner container 1. A plurality of through holes are opened in the sound absorption cotton 102, and the positions of the water leakage holes 101 correspond to the positions of the through holes. One ends of a plurality of shock absorption springs 203 are fixedly connected with the outer side of the shock absorption cylinder 201, and the other ends are fixedly connected with the inner wall of the washing machine shell;

[0024] When the washing machine starts to dehydrate, including when it is about to end dehydration, the inner container 1 rotates. The noise generated by the inner container 1 itself during rotation can be effectively absorbed by the sound absorption cotton 102 first. The shock absorption cylinder 201 rotatably connected with the bearing frame 202 can keep a fixed distance from the inner container 1. Then, the shock absorption springs 203 fixedly connected with the washing machine shell ensure that the inner container 1 will not be eccentric during rotation, ensuring that the inner container 1 will not collide with the washing machine shell during dehydration to generate noise. On the one hand, the service life of the inner container 1 is prolonged, avoiding the economic loss of users. On the other hand, the generation of collision noise is reduced, improving the use experience of users;

[0025] Inside the inner tank 1, a driving assembly 3 is provided. The driving assembly 3 includes an execution motor 302 for driving the inner tank 1 to work. The execution motor 302 is a driving component of a pulsator washing machine in the prior art. The execution motor 302 is fixedly arranged at the bottom of the inner tank 1. A sound insulation box 301 is arranged outside the execution motor 302. The output end of the execution motor 302 extends into the inner tank 1 and is provided with a partition plate 304. Several stirring rollers 305 for stirring clothes are arranged at the upper end of the partition plate 304. A sound absorption plate 303 for isolating the noise of the execution motor 302 is fixedly installed inside the sound insulation box 301. The material of the partition plate 304 is a sound insulation material;

[0026] When the driving assembly 3 operates, driving noise will be generated. By using the sound absorption plate inside the sound insulation box 301, the noise generated when the execution motor 302 operates can be absorbed by it. Moreover, since the partition plate 304 is made of sound insulation material, the noise generated by the execution motor 302 during the stirring of the washing machine can be isolated in the sound insulation box 301 and will not be transmitted to the inside of the washing machine through the vibration generated by the stirring of the stirring rollers 305, further improving the sound insulation and noise reduction effect of the washing machine and enhancing the practicality of the device.
