Description

[0001] WASHING MACHINE AND CONTROL METHOD [0002]

The present invention relates to a washing machine area, and particularly refers to a washing machine and a control method thereof.

Conventional washing machines often use an enclosed gimbaling, the contents of which are mostly liquid, iron or iron, and are sealed in an empty space of the gimbaling. When the washing machine is dehydrating at a high speed, the contents available in the empty space inside the jim baling based on the vibration point are moved to the position symmetrical with the load eccentricity of the washing machine, thereby reducing the eccentricity of the whole and reducing the vibration noise. The eccentricity of the washing machine is different every time. In particular, when the dehydration of a load such as a cotton wool is large, the jimbaling having the fixed contents can not perfectly balance the eccentric mass. At the same time, since the eccentricity is relatively small, the amount of the contents inside the gimbaling negatively affects the vibration, distribution and eccentricity calculation when rotating at a low speed. These factors greatly affect the eccentricity effect.

Conventional washing machines equilibrate the amount of eccentricity by using the movement of the contents in the inside of the gimbaling, the contents are sealed inside the gimbaling, and the contents are substances such as liquid, iron and iron, high. In addition, since the service life of the washing machine is close to several decades, the demand for the manufacturing technique of Jim Bulling is inevitably high, and thus the cost increases and the production efficiency is relatively low. Since the weight of the gimbaling and the inside of the gimbaling is large, there is a certain degree of difficulty in installing the washing machine.

The Chinese patent with the application number 200910158225.9 disclosed a kind of jumpering device of the drum washing machine as follows. The above-mentioned gimbaling device is composed of at least two round-shaped steel chambers in the periphery of the drum, and is installed coaxially with the drum. Among them, at least one steel chamber is a spherical gimbal ring having a ball inside, and at least one steel chamber is a liquid gimbal ring containing a flowing liquid. These two different equilibria, which are rolling balls and liquids, produce equilibrium forces of at least two different reaction rates, thereby improving the equilibrium when the drum of the washer is dehydrated. When the rotational speed is below the resonance point of the drum and the outer cylinder, it absorbs the vibration in the liquid imbalance. When the rotational speed is stabilized through the resonance point, it absorbs the vibration of the outer cylinder by exerting a powerful vibration absorbing function in the spherical gimbaling, The liquid imbalance absorbs the vibration. This gimbaling device achieves low vibration, low noise and low cost effects by controlling the vibration width of the outer cylinder when operating and when rotating stably. However, the gimbaling of the above-mentioned patent can not be adjusted based on the amount of eccentricity of the load of the washing machine after the mass of the internal equilibrium material is determined after being mounted on the washing machine and the contents of the inside of the jimbaling are rotated in the course of operation of the washing machine, Wasting energy consumption.

The present invention is presented in consideration of the above.

It is an object of the present invention to provide a kind of washing machine which overcomes the shortcomings of the existing technology. This washing machine includes an outer cylinder and an inner cylinder, and a gimbaling is provided at the washing throat inlet of the inner cylinder (1). The inside of Jim Bull ring is hollow space and there is no fixed contents. The weight of Bull ring is reduced. When the washing machine is operated, the contents inside Jim Bull ring are not rotated together, which reduces energy consumption. And the amount of water inside the general washing machine can not be changed by injecting an appropriate amount of water. The equilibrium is precisely controlled and the number of times of distribution is reduced, thereby greatly reducing the dewatering time.

Yet another object of the present invention is to provide a method of controlling the above-described washing machine.

In order to realize this object, the present invention applies the following technology. It is a type of washing machine, which includes an outer cylinder and an inner cylinder, and a gimbal ring at the inlet of the inner cylinder. This gimbaling has a round ring structure and has an injection port for balancing load eccentricity by the action of the equilibrium liquid by injecting water into the gimbaling in the inner circumferential direction. At least one on / off outlet is provided in the outer circumference.

The injection port is a one-round round ring-shaped injection port installed along the circumferential direction of the inside of the gimbaling, and the injection port is provided with injection parts. The injection part is a pipe fixed to the outer cylinder or the main body of the washing machine. One end of the pipe is inserted into the inlet of the gimbaling, but is not in contact with the inner wall of the jimbaling, and the other end is connected to the water supply pipe.

The above-mentioned injection part is provided with a drainage chamber for storing a part of water at the lower end of the outer cylinder as a pipe fixed and connected to the outer cylinder. The above-mentioned pipe is inserted into the injection port of the gimbaling, It is connected to a drain pump that drains or sends water through a drainage chamber.

A filter is installed at a position where the drainage chamber and the injection part are connected to each other. At the lower end of the drainage chamber, there is provided a discharge pipe penetrating the drainage pipe of the washing machine.

In the outer circumference of the above-mentioned gimbaling, a discharge port for discharging 2 to 10 equilibrium liquids is provided, and a discharge valve for controlling on / off of the discharge port is provided in the discharge port.

The above-mentioned drain valve is automatically turned on and off, and the drain valve includes one spring and one blocking plate. The spring is located at the outlet, one of the springs is connected to the outside of the outlet, and the other is connected to the blocking plate. The blocking plate is located inside the gimbaling. This blocking plate matches the shape of the discharge port, and when the above-mentioned spring is in a natural state, the discharge port is free from clogging and smooth. The above-mentioned drain valve is automatically turned on and off, and the above-mentioned discharge port has a "V" -shaped cross section and a movable spherical valve spool inside the "V" -shaped discharge port.

The above-mentioned control method of the washing machine is to equilibrate the load eccentricity of the inner cylinder when dehydration is performed by injecting water into the jumble ring through the inlet of the jimbaling.

After the dehydration distribution, the water is discharged from the washing machine, and the water injected into the jimbaling through the inlet of the jimbaling balances the eccentricity of the load when the inner cylinder is dehydrated. After the dehydration, the water inside the jimbaling is discharged through the outlet .

The amount of eccentricity is balanced by injecting tap water corresponding to the amount of eccentricity into the inside of the gimbaling through the gimbaling injection port based on the load eccentricity of the inner cylinder when the washing water is discharged and dehydrated and distributed before the dehydration distribution, After the dehydration is completed, the tap water inside the jimbaling is discharged through the outlet.

The washing water is discharged before the dehydration distribution and a part of the washing water is stored in the drainage chamber. On the basis of the load eccentricity of the inner cylinder when the dehydration distribution is performed, the drainage pump supplies the washing water corresponding to the amount of load eccentricity When the inner cylinder is dewatered by injection, the eccentricity of the internal load is balanced. After the dehydration is completed, the water inside the jimbaling is discharged through the outlet.

When the dehydration is proceeded, the inner cylinder rotates at a high speed, and the centrifugal force due to the rotation is larger than the spring resistance, so that the closure plate compresses the spring and the closure plate clings to the inner wall of the gimbals. When the centrifugal force becomes smaller than the restoring force of the spring, the resilience of the spring causes the blocking plate to return to the circle, The equilibrium liquid is discharged through the outlet. Or when the centrifugal force generated by rotating the inner cylinder at a high speed during dehydration is larger than the buoyancy of the spherical valve spool, the spherical valve spool is brought into close contact with the inner wall of the "v" When the centrifugal force becomes smaller than the buoyancy of the spherical valve spool, the spherical valve spool is brought into its natural state. When the centrifugal force is less than the buoyancy of the spherical valve spool, The equilibrium liquid is discharged through the outlet.

In the dehydration distribution, the amount of eccentricity of the internal cylinder is calculated by measuring the internal load eccentricity of the internal cylinder in the controller of the washing machine, and controlling the water pump to inject water corresponding to the load eccentricity into the jig baling. After the completion of dehydration, the manipulating glove valve is opened in the washing machine control section, and centrifugal force is exerted to discharge the water inside the deburring through the exhaust port.

The washing machine control unit controls the rotating speed of the inner cylinder to raise the rotating speed of the inner cylinder at a relatively high speed, and water is injected into the load baling of the washing machine to balance the load eccentricity.
