Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] see Figure 1-4 , a drum anti-collision device for a washing machine, comprising a housing 1, the inner wall of the middle part of the housing 1 is provided with a card slot suitable for the deceleration ring 2 and the inner side of the deceleration ring 2 is provided with a blocking block, when the drum 4 is rotating, it is in contact with the housing 1 When the inner wall collides, the barrier block will squeeze the trigger ball 5. The inner wall of t...

The invention relates to the technical field of washing machine drums, and discloses an anti-collision device for a drum of a washing machine. The anti-collision device comprises a shell, wherein a deceleration ring is fixedly connected to the inner wall of the middle of the shell, a drum is movably connected to the inner wall of the middle of the shell, a limiting groove is formed in the inner wall of the middle of the drum, and a pressing block is movably connected to the inner wall of the limiting groove. According to the anti-collision device for the drum of the washing machine, the drum drives a trigger ball to move, the trigger ball drives the pressing block to move, and a dielectric plate and a reset spring are used, so that the effect of detecting the shaking amplitude of the drum is achieved, when the drum rotates irregularly, the drum collides with the inner wall of the shell, the trigger ball makes contact with a blocking block on the inner side of the deceleration ring, the pressing block is extruded, the dielectric plate moves towards the inner side of the limiting groove under the action of the pressing block, the relative area of the positive plate and the negative plate is gradually increased, the voltage between the two plates is increased, at the moment, the minimum path voltage of a piezoresistor is achieved, and therefore the detection effect is achieved.
Description
technical field [0001] The invention relates to the technical field of washing machine drums, in particular to an anti-collision device for washing machine drums. Background technique [0002] With people's fast-paced life, washing machines have become an indispensable part of people's lives. They are widely used due to their simplicity, convenience, time-saving and labor-saving advantages. The drum part of the existing drum washing machine is mainly composed of two parts: The outer barrel is mainly used to hold the solution, and the inner barrel is used to wash clothes, etc. The outer barrel is fixed and connected with counterweights and other objects. The inner barrel is driven by a motor and reaches a certain speed to wash the clothes to achieve the effect of washing clothes. . [0003] During the use of the washing machine, due to the unevenness of the clothes put in the drum, the drum shakes a lot when it rotates. Due to the limited space around the drum, it often coll...
