Problems solved by technology

However, the vibration-reducing and energy-absorbing process of these structures is constant. During operation, when the vibration of the washing machine increases sharply due to factors such as entanglement of clothes, the vibration-damping amplitude of the vibration-damping spring changes suddenly. When the amplitude of the spring does not match, the vibration damping process is extremely uneven, which affects the vibration damping effect of the vibration damping component, thereby affecting the use effect of the washing machine

Embodiment 1

[0043] Such as figure 1 As shown, the special vibration damping device for pulsator washing machine includes: boom 1, one end of boom 1 is equipped with boom seat 2, the other end of boom 1 is provided with a stop 3, boom 1 is slidably installed with a guide The sleeve 4 and a spring support 5 are provided. The guide sleeve 4 is arranged between the boom base 2 and the limiting portion 3, and the spring support 5 is provided between the limiting portion 3 and the guide sleeve 4.

[0044] A damping spring 6 is arranged between the spring support 5 and the guide sleeve 4, and the damping spring 6 is sleeved on the boom 1.

[0045] A sleeve 7 is fixedly installed on the guide sleeve 4 away from the boom seat 2. One end of the sleeve 7 is opened, and the other end of the sleeve 7 is sealed. The spring holder 5 and the damping spring 6 are both arranged in the sleeve 7. The sleeve 7 is provided with a sliding cavity 8 for the spring holder 5 to slide, and the spring holder 5 is sleeved ...

Embodiment 2

[0055] Such as figure 2 As shown, the difference between this embodiment and the first embodiment is that: the second sleeve portion 18 is also connected to a third sleeve portion 20, and the third sleeve portion 20 is provided with a first air damping cavity. The second air damping cavity 21; the third sleeve portion 20 is installed with a limiting protrusion 22 that restricts the spring holder 5 from extending into the second air damping cavity 21. By providing the second air damping cavity 21, the damping cavity is increased In the space, when the air in the compression sleeve is compressed by the spring to dampen, the compressed air is guaranteed to enter the second air damping chamber 21 through the vent hole, thereby balancing the pressure in the sleeve 7, making the air damping smoother, and further improving the damping effect.

[0056] When the present invention is in use, the present invention is installed on the washing machine, the boom seat 2 is connected with the ou...

Abstract

The invention provides a special vibration damper for a pulsator washing machine. The special vibration damper comprises a hanging rod, a hanging rod seat is mounted at one end of the hanging rod, a limit portion is arranged at the other end of the hanging rod, a guide sleeve and a spring support are slidably mounted on the hanging rod, the guide sleeve is arranged between the hanging rod seat andthe limit portion, a damping spring is arranged between the spring support and the guide sleeve, damping is achieved by the aid of the damping spring, a sleeve is mounted on the guide sleeve, an opening is formed in one end of the sleeve, a damping ring is mounted on the spring support in a sleeving manner, the damping ring and the inner wall of the sleeve rub, the spring support drives the damping ring and the sleeve to rub when sliding to form frictional damping, so that damping effects are improved, the sleeve comprises a first sleeve portion mounted on the guide sleeve and a second sleeveportion connected onto the first sleeve portion, the opening diameter of the second sleeve portion is larger than that of the first sleeve portion, frictional force is improved when the spring support slides into the first sleeve portion from the second sleeve portion, and damping effects and use effects of the washing machine are further enhanced.

Description

Technical field [0001] The invention relates to the technical field of washing machines, in particular to a variable damping type vibration damping device for pulsator washing machines. Background technique [0002] The bottom of the pulsator washing machine is equipped with a pulsator. Driven by the pulsator, the water in the bucket forms a right-handed and left-handed vortex, which drives the fabric to rotate and tumble to clean the clothes. During the working process, due to the load of the washing items, the pulsator washing machine will resonate during the washing process. On the one hand, it increases the noise during work, and on the other hand, it can also cause damage to the pulsator washing machine. The damping component is used To bear the load of the entire washing machine and absorb vibration. [0003] At present, there are two types of damping devices used in pulsator washing machines at home and abroad. One is a pure friction damping device for small-capacity washin...
