Embodiment approach

[0047] As an embodiment of the present invention, an abutment surface 1311 is at least partially formed on the inner peripheral surface 131 of the matching portion 13, and the abutment surface 1311 can be a curved surface or a plane surface, preferably where the abutment surface 1311 is located. The plane intersects the axis of the suspension rod 2 , and a mating surface 3311 corresponding to the abutting surface 1311 is formed on the outer peripheral surface 331 of the damping adjustment part 3 . For example, only part of the matching portion 13 is formed as an inclined surface. When the inclined surface moves downward, the axial force can also decompose the radial force. The pressure gets high. In addition, there can be multiple such inclined surfaces as the abutting surface 1311 , which are evenly distributed along the circumferential direction. In addition, the inclined surfaces can be formed on the same tapered surface, or can be formed on different tapered surfaces.

Abstract

The invention relates to the field of living home appliances and discloses a suspension damping system and a washing machine. The suspension damping system comprises a suspended rod 2 and a damping assembly on the suspended rod, the damping assembly comprises a ball seat 10, a holder 20 and damping elastic parts 30, and at least a part of the inner circumference of the ball seat 10 is pressed andconnected onto the holder 20; the holder 20 comprises a damping adjustment part which can be in surface contact with the suspended rod 2, wherein when the ball seat 10 is stressed and moves toward theholder 20, the friction force between the damping adjustment part 3 and the suspended rod 2 is changed, so that the damping force is changed corresponding to the stress force of the ball seat 10; thevibrational energy of the system can be effectively reduced, and large vibration noise, drum collision, displacement and the like of the whole machine can be avoided; furthermore, the suspension system can be effectively driven to move, and the situation is avoided that vibration is transmitted to a shell of the washing machine and abnormal sound or vibration is generated.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a suspension damping system and a washing machine using the suspension damping system. Background technique [0002] As washing machines become more and more popular, the frequency of use is also higher and higher. Not only is it required that the washing machine can be flexibly applied to various washing loads, such as large washing loads such as quilt covers and down jackets or small washing loads such as a small amount of shirts, but also the user’s concern for running Noise requirements are also increasing, and quiet operation at night is also expected. [0003] Now the pulsator agitator washing machine mostly adopts the top-loading type, and uses the suspension shock-absorbing system to perform shock absorption to reduce noise. Suspension damping system, also known as boom assembly, now there are three main types: air boom, friction boom with independent friction damping unit...
