Description

 BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a six-point support type washing machine base,

The present invention relates to a base of a washing machine, in particular, a level lug is provided at three points of a base bottom, and a damper lug for damping vibration is provided therebetween so that all level lugs are brought into close contact with the ground surface, A 6-point support type washing machine base capable of reducing noise and vibration when the washing machine is operated, and a washing machine supporting method using the same.

Generally, a washing machine forcibly rotates washing water, thereby separating foreign substances from the laundry by the friction between the water and the laundry and the emulsifying action of the detergent. In such a washing machine, the bottom surface is fixed by a floor fixing material, and the general type is a level fixing type for leveling.

The washing machine is operated by rotation of the washing machine during washing and dewatering. In particular, when the laundry of the washing machine is rotated in one direction in the washing machine in the case of dewatering, rotation of the washing machine occurs. The rotational vibration of the washing tub causes the entire vibration of the washing machine, and this vibration breaks the initial horizontal of the washing machine floor fixing support device and the bottom fixed maintenance of the supporting device, thereby causing a larger vibration. These vibrations are necessary to eliminate the noise due to the operating noise and the failure of the washing machine.

To this end, as shown in FIG. 1, a base 3 is installed on the bottom surface of the washing machine 1, and level lugs 4 are installed on the bottom surface of the base 3 to attenuate initial horizontal and vibration do.

However, in the conventional technique, the level lag is configured as a four-point structure that is provided at the corner of the base bottom as described above. In order to maintain the level of the washing machine, the height of the level lag must be adjusted to level the washing machine.

 At this time, the bottom of the level lag should be in close contact with the ground, but in the case of the four-point supporting structure, it is not easy to align the level of the washing machine. That is, in the case of the four-point supporting structure, the floor is spaced a certain distance from the floor, that is, the floor at one point, so that it is difficult to level the washing machine.

Further, as described above, it is general that one level lag appears to be in close contact with the ground surface at first glance, but is not substantially in close contact with the ground surface. In this case, since the weight of the washing machine is not uniformly distributed in the level lag, the load unevenness gradually occurs due to the vibration of the washing machine, which causes the washing machine to shake and noise more seriously.

On the other hand, the technique of the base for supporting the washing machine as described above is widely used, and in particular, is described in detail in the following prior art documents.

Example

The washing machine base B according to an embodiment of the present invention includes a plurality of level lugs 100 and a plurality of damper lugs 200 disposed on the bottom of the washing machine base B as shown in FIG.

A pair of corner level lugs 100-2 are disposed at the two corners of one side of the bottom surface of the base B and three corner lugs 100-2 are disposed. And a center level lug 100-1 installed at a central portion of an opposite side surface of the side surface on which the base plate 100 is installed.

That is, as shown in the drawing, a corner level lug 100-2 is provided on the right side edge of the bottom surface of the base B, respectively, and the center level lug 100-1 is provided on the center portion of the left side surface, Can be installed.

When the level lug 100 is installed at the three points as described above, all the level lugs are brought into close contact with the ground surface as compared with the existing four-point level lag system.

This is because, in the case of the four-point level lag system, there is a case where one level lag can not be brought into close contact with the paper surface. However, in the three-point level lag system as in the present invention, Through some elastic deformation all the level lugs are brought into close contact with the ground.

According to the present invention, the level of the washing machine can be easily adjusted and the vibration can be reliably attenuated.

Meanwhile, three damper lugs 200 are provided between the three-point level lugs 100 of the present invention.

As shown in the figure, the bridge rails 200 include a center damper lug 200-1 disposed between the pair of corner level lugs 100-2 and a center damper lug 200-1 disposed on both sides of the center level lug 100-1. And a corner damper lug 200-2.

That is, as in the embodiment shown in FIG. 2, a pair of corner level lugs 100-2 are provided on the right side of the bottom surface of the base B in the drawing, and a center damper lug 200-1 is installed therebetween .

In addition, the corner damper lug 200-2 is installed at the corner of the left side in the drawing, and the center level lug 100-1 is installed therebetween.

At this time, the damper lug 200 is for damping the vibration of the washing machine, and may be used without limitation as long as it is an elastic material such as rubber.

It is preferable that the damper lugs 200 are disposed in the front-rear direction (direction 2 in Fig. 1) of the washing machine.

This is because the vibration of the washing machine in the front-rear direction is strongest, so that the damper lugs 200 are arranged in the front-rear direction of the washing machine as described above.

As described above, in the present invention, the three-level lug 100 and the three damper lugs 200 are included to provide a six-point support type washing machine base.

Meanwhile, the level lug 100 may be an existing one as shown in FIG. 1, but the present invention described below can also be used.

The level lug 100 of the present invention for this purpose can include the adsorption unit 110 and the pressurization unit 120 as shown in FIG.

As described later, the adsorption unit 110 is provided with a pressing unit 120 for pressing the adsorption unit 120 so as to enhance the adherence of the adsorption unit 110 to the ground, It is for this reason.

3 and 4, the height regulating unit 130 may be installed in the pressing bar 121 of the pressing unit 120. In this case, That is, for example, a thread is formed on the outer surface of the pressing bar 121, and then the height adjusting part 130 is screwed to the pressing bar 121.

With this structure, the height of the base B can be adjusted by rotating the height adjuster 130. Since the configuration of the height adjuster 130 is widely known, the description and illustration are omitted.

6 to 7, the adsorption unit 110 may include a suction unit main body 111 having a hollow shape and an opening 111-1 formed at an upper part thereof. At this time, The bottom surface of the sub-main body 111 is formed so as to be spaced apart from the ground surface by a predetermined distance.

That is, as shown in FIG. 6, the bottom surface 111-2 of the adsorption unit main body 111 is formed to be spaced apart from the ground so that the central portion thereof is spaced upward in the drawing. For example, 111 may be formed so as to have a distance L between the center of the bottom surface 111-2 and the ground.

The pressing portion 120 is provided on the bottom surface of the base B and has a bar shape to enter the inside of the adsorption portion main body 111 through the opening portion 111-1 of the adsorption portion main body 111 And a pressure plate 122 installed at one side of the pressure bar 121 and installed inside the adsorption unit main body 111. The pressure bar 122 includes a pressure bar 121,

2 and 5, one side of the pressure bar 121 is provided on the bottom surface of the base B and the other side is connected to the adsorption unit main body 111 as shown in FIGS. 6 and 7, And enters the inside of the adsorption unit main body 111 through the open portion 111-1 of the adsorption unit main body 111. [

At this time, the pressure plate 122 is installed in the pressure bar 121 and is disposed inside the adsorption unit main body 111, and the pressure plate 122 moves the bottom surface of the adsorption unit main body 111 in the paper surface direction Upper and lower directions).

 The suction unit main body 111 includes a suction unit discharge hole 111-3 formed to penetrate a part of a bottom surface 111-2 of the suction unit main body 111 and the pressure plate 122 is formed to penetrate in a height direction And a pressure plate discharge hole 122-1 communicating with the suction portion discharge hole 111-3.

That is, when the pressure plate 120 presses the bottom surface 111-2 of the suction unit main body 111 in the paper surface direction (lower side in the drawing), the bottom surface 111-2 is closely attached to the paper surface, The air remaining between the surface 111-2 and the surface of the sheet is discharged upward in the figure along the suction portion discharge hole 111-3 and the pressure plate discharge hole 122-1.

By this action, the bottom surface 111-2 is brought into close contact with the paper surface, and the adsorption performance is improved, whereby the base B can be more firmly fixed to the paper surface. As a result, when the washing machine is disposed on the base (B) of the present invention, a remarkable attenuation performance can be obtained by the present invention.

The adsorption unit 110 is formed around the opening 111-1 of the adsorption unit main body 111 and protrudes toward the center of the opening 111-1 so that the pressure plate discharge holes 122-1 And a movable piece 112 made of an elastic material covering the upper surface of the movable piece 112.

That is, the air between the bottom surface 111-2 of the adsorption unit main body 111 and the ground surface is directed upward along the adsorption unit discharge holes 111-3 and the pressure plate discharge holes 122-1 as described above And the movable piece 112 is installed to prevent the air from being introduced again after the air is discharged.

When the air is exhausted by the movable piece 112 made of elastic material, the movable piece 112 is deformed in the upward direction in the drawing. After the air is discharged, the movable piece 112 is returned to its original position by the elastic force, And covers the pressure plate discharge hole 122-1.

As a result, ambient air can be prevented from entering the pressure plate discharge hole 122-1, so that the attraction force can be improved.

6 and 7, two suction port exhaust holes 111-3 and a pressure plate discharge hole 122-1 are provided facing each other, and the movable piece 112 is connected to the second pressure plate discharge hole 111-3, And two are arranged so as to cover the light guide plate 122-1.

However, the present invention is only one example for explaining the present invention, and the present invention is not limited by the shape and number of the suction part discharge hole, the pressure plate discharge hole, and the movable piece as long as the above- The absence is obvious.

The level lag 100 of the present invention may also include a corner level lag 100-2 and a center level lag 100-1 as described above, The lag 100-1 may have the same configuration as described above.
