Technical Field

[0001] The present invention relates to the technical field of washing machine accessories, and specifically relates to a washing machine counterweight assembly with adjustable counterweight. Background Art

[0002] During the high-speed dehydration process of a washing machine, due to uneven distribution or eccentricity of the clothes, violent vibrations are likely to occur, which may even cause equipment damage or displacement; and the washing machine counterweight assembly is a crucial component in the washing machine structure. Its core function is to achieve dynamic balance of the washing machine during high-speed operation by increasing the weight of specific parts, and to avoid violent vibrations or displacements of the body caused by centrifugal force;

[0003] The existing washing machine counterweight assemblies usually use cement or cast iron materials with fixed weights, and cannot dynamically adjust the counterweight according to actual needs, resulting in insufficient stability of the washing machine when dealing with different loads; at the same time, the washing machine is generally in a humid and sealed environment, and since the bottom of the washing machine is close to the ground and there is a lack of air circulation, moisture cannot be discharged in time and is easily condensed into water droplets, which not only causes rust on the washing machine shell and internal metal parts, but also easily breeds mold, affecting the internal hygiene of the washing machine. Summary of the Invention

[0004] The technical problems solved by this solution are as follows:

[0005] (1) How to solve the problem that due to the bottom of the washing machine being close to the ground and lacking air circulation, moisture cannot be discharged in time, which not only causes rust on the washing machine shell and internal metal parts, but also easily breeds mold, affecting the internal hygiene of the washing machine;

At this time, the second piston blocks the pressurizing hose, and the air flows out from the output ends of the first blowing hose and the second blowing hose respectively. The air flow blown out from the first blowing hose will carry the moisture at the bottom of the washing machine body out through a plurality of ventilation holes, avoiding the growth of mold caused by this moisture and affecting the hygiene inside the washing machine body. And the air flow blown out from the second blowing hose is heated by the electric heating plate and then blown out from the output end of the hot air pipe to ventilate the lower part of the working box, facilitating the rapid drying of the moisture between the working box and the ground and preventing the outer shell of the washing machine body and its internal metal components from rusting.

[0038] Please refer to Figure 5 As shown, a hot air pipe 404 is fixedly inserted on the outer wall of the above-mentioned water storage tank 407. The input end of the hot air pipe 404 is located in the heat conduction cover 406, and the output end of the hot air pipe 404 faces the lower part of the working box 3; by controlling the extended end of the electric push rod 703 to be the shortest, at this time, the first piston 704 blocks the output end of the connecting pipe 705, and the second piston 708 is located at the end of the second adjusting cylinder 711 away from the pressurization hose 707. Then, turn on the blower 6 to make the air flow into the water storage tank 407, increase the air pressure, facilitate the injection of clean water into the counterweight box 403, and then cooperate with the opening and closing control valve 401 to facilitate the excess clean water in the counterweight box 403 to flow back along the return water hose 402, adjust the content of the clean water entering the counterweight box 403, play a role in dynamically adjusting the weight of the counterweight box 403 according to actual needs, and avoid insufficient stability of the washing machine body 5 when dealing with different loads.

[0040] Please refer to Figure 1 As shown, a plurality of ventilation holes 1 are equidistantly arranged on the outer wall of the above-mentioned fixing ring 2.

[0041] Working principle: When the present invention is in use, first, turn on the electric heating plate 405, and then cooperate with the heat conduction cover 406 to transfer heat to the clear water in the water storage tank 407, preventing the clear water in the water storage tank 407 from freezing due to the low external temperature, which affects the efficiency of filling the counterweight box 403 with clear water; by controlling the extending end of the electric push rod 703 to be the shortest, at this time, the first piston 704 blocks the output end of the connecting pipe 705, and the second piston 708 is located at the end of the second adjusting cylinder 711 away from the supercharging hose 707. Then turn on the blower 6, so that the air flow is injected into the water storage tank 407 through the L-shaped pipe 706 and the supercharging hose 707, increasing the air pressure inside it, facilitating the clear water to be injected into the counterweight box 403 along the water inlet hose 408. Then cooperate with the opening and closing control valve 401 to facilitate the excess clear water in the counterweight box 403 to flow back to the water storage tank 407 along the water return hose 402. By adjusting the content of the clear water entering the counterweight box 403, the weight of the counterweight box 403 can be dynamically adjusted according to actual needs, avoiding the problem of insufficient stability when the washing machine body 5 processes different loads; after filling the counterweight box 403 with an appropriate amount of clear water, control the extending end of the electric push rod 703 to extend to the longest, so that the first piston 704 slides to the end of the first adjusting cylinder 710 close to the second adjusting cylinder 711, and the second piston 708 slides to contact the input end of the supercharging hose 707. At this time, both the first air blowing hose 702 and the second air blowing hose 709 are communicated with the connecting pipe 705.

The air flow blown out from the first air blowing hose 702 will carry the moisture at the bottom of the washing machine body 5 out through several ventilation holes 1, preventing these moisture from breeding mold and affecting the hygiene inside the washing machine body 5. The air flow blown out from the second air blowing hose 709 enters the heat conduction cover 406, is heated by the electric heating plate 405, and then blows out from the output end of the hot air pipe 404 to ventilate the lower part of the working box 3, facilitating the rapid drying of the moisture between the working box 3 and the ground, and preventing the outer shell of the washing machine body 5 and its internal metal components from rusting.
