Description

Technical Field

[0001] The invention relates to the technical field of counterweights, and in particular to a washing machine counterweight with adjustable counterweight. Background Art

[0002] There are counterweights inside the washing machine to give it a certain weight, which is used to reduce the vibration and shaking of the washing machine during operation and ensure its stability and balance;

[0003] The utility model with the announcement number CN217810097U specifically discloses a weight block for a washing machine with adjustable weight. The weight block can be separated from the adjustment slot, and weight blocks of different weights can be replaced to adapt to different types of working environments and improve the use effect of the washing machine. In addition, during long-term work, weight blocks of different sizes can be hidden through the adjustment slot, which does not affect the occupied volume after the weight is counterbalanced. The structure is simple, convenient and practical.

[0004] The device adjusts the washing machine weight by adding different numbers of counterweights, but in actual use, the washing machine will generate vibrations of a certain frequency during operation, and the force generated by the vibrations will be fed back to the multiple stacked counterweights, causing collisions, wear and even noise between the multiple counterweights, affecting the use of the device. The counterweights in the prior art are often cast in concrete, and counterweights of different masses are used according to the size of the washing machine. This method also has defects in actual use. The counterweights made of concrete are easily damaged during installation and disassembly if the user accidentally drops them or collides with the ground. In addition, the counterweights made of concrete are easily oxidized and cracked during long-term use.

[0005] Therefore, a washing machine counterweight with adjustable counterweight is proposed. Summary of the invention

[0006] The object of the present invention is to provide a washing machine counterweight with adjustable counterweight. The configuration structure designed in the present application is simple and convenient to operate, and has low manufacturing cost. Counterweight balls and configuration particles made of ceramic waste or glass waste are used. When the overall counterweight mass needs to be adjusted, counterweight balls or configuration particles of different masses can be added to the counterweight cylinder. A vibration motor is used to vibrate and balance the internal counterweight balls or configuration particles, and then the internal counterweight balls or configuration particles are fixed by airbag expansion or electrorheological fluid conductive solidification, thereby ensuring the overall counterweight structure problem to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a counterweight block for a washing machine with adjustable counterweight, comprising a counterweight barrel, the top of the counterweight barrel is fixedly connected to an air box, the air box is embedded with an injection valve, the air box is connected to the counterweight barrel by a communicating design, and a threaded air bag is arranged on the upper side of the inside of the air box, the top of the threaded air bag is connected to the air box, and the threaded air bag is connected to the injection valve, the counterweight barrel and the air box are fixed by screws, the bottom of the counterweight barrel is fixedly connected to a flange, the lower end surface of the flange is embedded with a vibration motor, a feed port is provided on the outer surface of the counterweight barrel near the upper side, a sealing plate is fixedly connected to the inside of the feed port by screws, counterweight balls are injected into the interior of the counterweight barrel through the feed port, and the counterweight balls include ceramic particles and glass particles.

[0009] Preferably, magnetorheological fluid is injected into the interior of the counterweight barrel through a liquid injection valve, and an electromagnet with a strip structure is fixedly connected to the inner wall of the counterweight barrel.

[0010] Preferably, the ceramic particles include the following components by weight:

[0011] Main component: 95% alumina ceramic, of which the content of corundum alumina is 95%, and the particle size is 1-3μm;

[0012] Flux: 3% titanium dioxide, 2% yttrium oxide.

After ball milling, dry the mixed slurry at 80℃-100℃ to obtain evenly mixed ceramic powder;

[0018] Molding: Dry pressing and static pressing are used to make the mixed powder into a green body of the desired shape.

Spray granulation is to spray the glass liquid into the hot air flow through a high-pressure nozzle, so that the glass liquid is quickly cooled and solidified into particles; drip molding is to drip the glass liquid drop by drop through a special dripper, and solidify into particles in the cooling medium;

[0024] Annealing treatment: Put the prepared glass particles into an annealing furnace and perform annealing treatment at the glass transition temperature of 500℃-600℃ to eliminate the stress inside the particles and improve their strength and stability;

[0025] Surface treatment: Surface treatment is performed on the glass particles. The surface of the glass particles is coated with a silane coupling agent to form a waterproof film on the surface of the particles to enhance its waterproof effect.
