Description

Technical Field

[0001] This utility model relates to the field of washing machine accessories technology, and in particular to a washing machine inner drum counterweight balancing component that is easy to install. Background Technology

[0002] During the high-speed rotation of the washing machine drum, uneven distribution of clothes can easily cause eccentric vibration, leading to machine shaking, increased noise, and even damage to parts. Therefore, the counterweight balancing component is a key part of the washing machine drum, and its function is to counteract centrifugal force through counterweight adjustment to ensure stable operation.

[0003] However, existing washing machine drum counterweight balancing components still have the following two shortcomings in use:

[0004] First, traditional counterweights are mostly fixed metal blocks that need to be customized according to the washing machine model. They cannot dynamically adjust the balancing torque for different washing loads, such as the weight and distribution of clothes, resulting in limited eccentric vibration suppression effect.

[0005] Secondly, some adjustable counterweight structures are fixed with bolts or connected with slots, but the adjustment process requires disassembling multiple parts, which is cumbersome. Special tools are required for installation, and the inner cylinder structure is easily damaged during disassembly, resulting in high maintenance costs. Utility Model Content

[0039] Cover plate 4 is located on the outer end face of purification box 3, and purification holes 401 are evenly opened on the surface of cover plate 4.

[0040] The purification box 3 has a first mounting hole 301 on its surface, and the cover plate 4 has two second mounting holes 402 on its surface. The cover plate 4 is connected to the purification box 3 by bolts. The purification box 3 is filled with activated carbon.

[0041] The upper end of the cylinder 1 is threaded with retaining rings 101 at both ends. The inner end face of the retaining rings 101 is threaded. In use, the upper and lower ends of the outer end face of the cylinder 1 are threaded, and the inner end face of the retaining rings 101 is threaded. The worker can thread the retaining rings 101 to the outside of the cylinder 1. The lower end of the counterweight 2021 is in contact with the lower retaining ring 101, and the upper end of the counterweight 2021 is in contact with the upper retaining ring 101, which can achieve the fixed positioning of the counterweight 2021.

[0042] The surface of the fixing belt 2 has two symmetrical connecting holes 201. The connecting screw 103 on the outer end face of the cylinder 1 is engaged in the connecting hole 201 on the surface of the fixing belt 2. A nut is connected to the surface of the connecting screw 103.

[0043] The inner end face of the cylinder 1 is uniformly equipped with barrier strips 5. The surface of the barrier strips 5 is uniformly provided with V-shaped grooves 501. During use, when the cylinder 1 rotates, the clothes inside the cylinder 1 will stick to the barrier strips 5, which can increase the friction between the clothes and the barrier strips 5. The grooves 501 uniformly provided on the surface of the barrier strips 5 facilitate the passage of water.

[0044] Among them, the outer end face of the fixing belt 2 is evenly installed with the limiting cylinder 202, and the inside of the limiting cylinder 202 is clamped with the counterweight 2021. The upper and lower ends of the counterweight 2021 are respectively attached to the two retaining rings 101. During use, when the cylinder 1 rotates, if the clothes are unevenly distributed and eccentric vibration occurs, the counterweight 2021 generates a reverse torque due to inertia, which is transmitted to the cylinder 1 through the fixing belt 2, which can counteract the centrifugal force.

[0045] The working principle of this embodiment is as follows: In this utility model, two sets of connecting screws 103 are symmetrically installed on the outer end face of the cylinder 1.

The worker attaches a nut to the surface of the connecting screw 103. After the worker tightens the nut, the fixing band 2 can be fixed. Limiting cylinders 202 are evenly installed on the outer end face of the fixing band 2. The worker can snap the counterweight 2021 into the inside of the limiting cylinder 202. The outer end face is threaded at both the top and bottom, and the inner end face of the retaining ring 101 is threaded. Workers can thread the retaining ring 101 onto the outside of the cylinder 1. The lower end of the counterweight 2021 fits against the lower retaining ring 101, and the upper end of the counterweight 2021 fits against the upper retaining ring 101. Through holes 102 are evenly distributed on the surface of the cylinder 1 to facilitate the outward flow of water from inside the cylinder 1. Barrier strips 5 are evenly installed inside the cylinder 1. During rotation, clothing inside the cylinder 1 will adhere to the barrier strips 5, increasing the chance of water loss. The friction between the object and the barrier strip 5 is reduced, and the surface of the barrier strip 5 is evenly provided with grooves 501 to facilitate water passage. The fixing strap 2 is made of elastic material, and the fixing strap 2 and the counterweight strip 2021 work together to absorb the small vibrations when the cylinder 1 rotates. Two purification boxes 3 are symmetrically installed inside the cylinder 1. The purification boxes 3 are filled with activated carbon, and the left and right ends of the purification boxes 3 are inclined to reduce the impact of water flow. The surface of the cover plate 4 is provided with a second mounting hole 402, and the surface of the purification box 3 is provided with a first mounting hole 301. By passing through the second mounting hole 402 and threaded into the first mounting hole 301, the cover plate 4 can be fixed to the surface of the purification box 3. The activated carbon inside the purification box 3 adsorbs the sweat odor, detergent residue odor and small impurities generated during the washing process. The purification hole 401 is kept unobstructed. The cover plate 4 is connected to the purification box 3 by bolts, which facilitates the regular replacement of activated carbon. When the drum 1 rotates, if the clothes are unevenly distributed and cause eccentric vibration, the counterweight 2021 generates a reverse torque due to inertia, which is transmitted to the drum 1 through the fixing belt 2, which can counteract the centrifugal force.
