Description

Suspension for washing machine

The present invention relates to a suspension device for a washing machine, and in particular, when vibration or shock is applied in the vertical direction, the vibration and shock in the vertical direction are absorbed by the elasticity of the compression coil spring built into the housing, and the vibration or When the impact is applied to a suspension device for a washing machine configured to effectively reduce the vibration and impact in the washing and dehydration process by absorbing vibration or shock by the compression coil spring of the auxiliary housing.

Generally, in a pulsator type washing machine in which washing is performed by the formation of water flow generated by the operation of a pulsator provided inside a washing tank, a one-type washing machine made of the same washing and dehydration in a washing tank is excessive vibration of the washing tank during washing or dehydration. Suspension is installed outside the reservoir to prevent noise and flow.

1 is a suspension device 150 for a washing machine 150 connected to a storage tank 160 coupled to an outside of a washing tank 170 and an outer box 180 to support the storage tank 160 in the one-type washing machine 200 as described above. As shown in the drawing, the conventional suspension device 150 has a structure in which the supporting rod 141 is connected between the connection member 160A protruding from the lower side of the reservoir 160 and the upper end of the outer box 180. Is done.

The present invention as described above is a housing 10 coupled to the lower portion of the reservoir 70, the support rod 20 is connected to the housing 10, the horizontal support rod 30 is connected to the upper peripheral surface of the reservoir 70 and the It consists of a first auxiliary housing 40 and a second auxiliary housing 45 connected to the tip of one horizontal support bar (30).

The housing 10 is located at the lower portion of the connecting member 61 protruding horizontally from the reservoir 70, the compression coil spring (1) is coupled to the inside, the upper through hole is the corner of the outer shell (80) The front end of the support bar 20 is elastically supported by the elasticity of the compression coil spring 1 by inserting the front end of the support bar 20 hinged from the top.

Subsequently, the horizontal support rod 30 connected horizontally from the upper portion of the reservoir 70 to support the upper portion of the reservoir 70 is hingedly connected to the reservoir 70 in the vertical direction from the reservoir 70. It has a rotatable structure.

The horizontal support rod 30 is integrally connected to the rod 21, 22 branched in parallel to the other end of the connection with the hinged reservoir 70, the front end of the rod (21, 22) is the first auxiliary housing The elasticity of the compression coil springs 31 and 32 inserted into the through holes of the 40 and second auxiliary housings 45, respectively, and embedded in the first and second auxiliary housings 40 and 80, respectively. Receive.

Meanwhile, connecting rods 33 and 34 are arranged in parallel between the first auxiliary housing 40 and the second auxiliary housing 45, and the supporting rods 20 are connected between the connecting rods 33 and 34. By interposing, the rotation angle with respect to the upper part and the lower part of the horizontal support rod 30 from a horizontal surface is regulated.

Suspension device for the washing machine 50 according to the present invention is such that the shock is absorbed by the elasticity of the compression coil spring (1) built in the housing 10 when the pressing force acts in the vertical direction of the water tank (70), When the pressing force according to the impact acts in the horizontal direction of the reservoir 70, the pressing force applied in the horizontal direction by the compression coil springs 31 and 32 of the first auxiliary housing 40 and the second auxiliary housing 45 disappears. Let's do it.

By interposing between 34), the rotation angle of the upper and lower portions of the horizontal support bar 30 from the horizontal plane is regulated.

On the other hand, as described above, the present invention coupled between the trauma 80 and the reservoir 70 is installed between the reservoir 70 from each inside of each corner of the trauma 80 to install four tanks from the inside of the washing machine, respectively. .

When the pressing force acts in the vertical direction of the water storage tank 70 during the washing process, the present invention coupled as described above may be applied to the housing 10 coupled to the lower side of the water storage tank 70, such as a suspension device for a washing machine of a conventional structure. The compression coil spring 1 absorbs the shock by the buffer force generated during the compression process.

That is, for example, when the reservoir 70 is lowered as shown in FIG. 4A, the compression coil spring 1 embedded in the housing 10 is compressed to absorb shocks according to the characteristics of the support rod 30 having a predetermined length. When the pressing force acting in the vertical direction of the reservoir 70 is removed, the reservoir 70 is returned to the initial position by the elasticity of the compression coil spring 1.

Subsequently, when the pressing force acts in the horizontal direction from the water tank 70 such as when the rotation direction of the pulsator is switched or when stopped, the horizontal supporting rod 30 moves in the same direction as the acting direction of the pressing force, as shown in FIG. 4B. The rods 21 and 22 at the tip of the horizontal support rod 30 are inserted into the first auxiliary housing 40 and the second auxiliary housing 45.

In this process, as the compression coil springs 31 and 32 are embedded in the first auxiliary housing 40 and the second auxiliary housing 45, the compression coils are inserted according to the insertion of the rods 21 and 22. By compressing the springs 31 and 32, respectively, the pressing force acting in the horizontal direction is absorbed by the elasticity, thereby eliminating vibration and impact acting in the horizontal direction.

As described above, the present invention absorbs the vibration and shock in the vertical direction by the elasticity of the compression coil spring 1 embedded in the housing 10 when the vibration or the shock is applied in the vertical direction, and acts in the horizontal direction. When the vibration or shock acts, the compression coil springs 31 and 32 embedded in the first auxiliary housing 40 and the second auxiliary housing 45 absorb vibration or shock.

Therefore, the present invention can eliminate the pressing force acting in the vertical direction, as well as suppress the occurrence of vibration or shock even when the pressing force acts in the horizontal direction from the water tank 70 such as when the rotation direction of the pulsator is switched or stopped. Therefore, it is possible to effectively reduce the vibration, shock and noise generated during the washing and dehydration process, there are many effects such as to prevent the life of the drive device including the motor is reduced.
