The present invention relates to a support leg of a washing machine, and in particular, to provide an air spring on the support leg of the washing machine to absorb and prevent vibration generated in the washing machine.

In general, not only a washing machine but also commercial and home electric appliances include a plurality of support legs on the bottom surface for supporting the main body stably from the ground, and most of these support legs are simply installed as a fixture for supporting the main body, or Since only the height adjustment mechanism for adjusting the height of the support legs, there was a problem that can not prevent the vibration generated in the main body at all.

Particularly, in the case of a washing tank and a pulsator in which the rotation ratio is rotated differently according to the washing process, such as a washing machine, the vibration degree and the imbalance of the vibration are severe according to the amount and the state of the laundry, thereby preventing its vibration. There was a need for a structural device for this, and accordingly, various types of vibration preventing devices for absorbing and preventing vibration generated in a rotating body such as a washing tank and a pulsator were proposed and used in the washing machine.

However, even if the washing machine is provided with a device for preventing vibration therein, it completely absorbs the unusual excessive vibration generated due to the amount and state of the laundry or the installation horizontality and carelessness of the washing machine. There was a problem such as that the support capacity of the washing machine is lowered to prevent it, causing a malfunction of the washing machine.

Therefore, the present invention has been made in consideration of the above circumstances, and its object is to damage the device by efficiently absorbing and preventing vibrations and shocks generated in the main body while supporting the main body in a washing machine as well as commercial and household electrical appliances. It is to provide a support leg of the washing machine to prevent noise and at the same time reduce noise.

This object is achieved by having a cushioning member having an annular air chamber which is formed of relatively soft rubber and filled with compressed air therein, and an adjusting member which is screwed under the buffer member to adjust the height of the main body. That is, the thickness of the inner and outer circumferential walls constituting the air chamber of the buffer member is made thinner than the thickness of the upper and lower limbs, so that the dynamic displacement in the vertical direction as well as the unique and dynamic displacement in each direction, i. Absorption and attenuation at the same time, and also, to adjust the height of the main body by loosening and tightening the adjustment member screwed to the buffer member, and at the same time the cushioning member is provided with a cushioning rubber support for the vibration prevention efficiency It is characterized by further improving.

Subsequently, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 2 of the drawings show an embodiment of the present invention, the reference numeral 10 in the figure is the body of the support leg.

Its body 10 is fastened to the bottom of a plurality of commercial and household electrical appliances, such as the washing machine (1) as in the usual, and securely supports it, is fastened to the bottom of the washing machine (1) to absorb the vibration generated in the washing machine And a damping member 11 to attenuate, and an adjusting member 12 to be screwed into the lower portion of the buffer member 11 to adjust the height.

That is, the shock absorbing member 11 is provided in an annular shape by the inner and outer circumferential walls 13 and 14 and the upper and lower support portions 15 and 16, and the air chamber is filled with compressed air to absorb and attenuate vibration ( 17) and a through-hole 20 provided in the vertical direction in the center portion and having a locking jaw 19 to which the fastening bolt 18 is fastened to the top thereof, and also integrally molded in the lower portion of the through-hole 20. The adjustment member 12 to be described later in the inner diameter is composed of a nut 21 is screwed.

In addition, the adjusting member 12 is integrally molded in the lower part and has a constant elasticity, and the support hole 22 is in contact with the ground, and is provided to protrude upward in the center of the upper and the nut of the above-mentioned buffer member (11) It is configured with a control bolt 23 screwed to (21).

At this time, the inner circumferential wall 13 of the above-mentioned shock absorbing member 11 is formed to a thickness such that it does not expand when the compressed air is filled in the air chamber 17 so that the inner diameter of the through hole 20 is not reduced. At the same time, the outer circumferential wall 14 is configured to be thinner than the inner circumferential wall 13 while being configured to have a thickness that is not excessively expanded to the outside, so that when vibration is transmitted, the outer circumferential wall 14 is expanded and contracted not only vertically but also horizontally.

In addition, Figure 3 is a modification of the means for fastening and fixing the shock absorbing member 11 to the bottom surface of the washing machine 1 as another embodiment of the present invention, that is, the circular bracket 24 on the upper end of the shock absorbing member 11 is integrated It will be possible to fasten and secure the shock absorbing member 11 by a plurality of fastening bolts 25 by molding, and also Figure 4 shows another embodiment of the present invention, which is a through hole 20 of the shock absorbing member 11 By sealing the lower part and removing the adjusting member 12, it may be suitably used for a product that does not need height adjustment.

Therefore, the present invention configured as described above, if vibration is transmitted from the inside of the washing machine 1 to the support leg 10 of the main body, the vibration of the air through the inner and outer circumferential walls 13, 14 of the buffer member (11). It is absorbed and attenuated by the yarn 17.

In other words, the vibration transmitted from the main body 1 is first transmitted to the upper support part 15 of the shock absorbing member 11, where the shock absorbing member 11 depends on the shape and size of the dynamic displacement applied to the upper support part 15. The air chamber 17 of the expansion and contraction in the vertical and horizontal directions is to absorb and attenuate the dynamic displacement.

At this time, the inner and outer circumferential wall (13, 14) is accommodated as the shape of the air chamber 17 is expanded and contracted as it is deformed, and when the vibration is eliminated is to be returned to its original position by its elastic force.

On the other hand, the vibration transmitted to the outside of the main body 1 is also absorbed and attenuated again by the elastic force itself in the support 22 provided in the lower portion of the adjusting member 12.

Therefore, the present invention has an effect of reliably and safely supporting the product by efficiently absorbing and attenuating excessive vibration generated in the interior of commercial and household electrical appliances such as washing machines and the like, even outside the main body.
