Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration isolator for a dehydration washing machine for washing and dehydrating clothes and the like.

2. Description of the Related Art Conventionally, this type of dewatering washing machine has a structure as shown in FIG. 4, for example, as disclosed in Japanese Utility Model Publication No. 49-30710. That is, in the figure, 1 is the main body of the dehydration washing machine, 2
Is a washing and dewatering tank with a plurality of dewatering holes 3 formed in the inner peripheral wall,
Reference numeral 4 denotes a laundry receiving tub in which the washing / dehydrating tub 2 is rotatably installed inside, 5 is a stirring blade provided at a central bottom portion of the washing / dehydrating tub 2, 6
Is a transmission mechanism, which has a reduction gear and a
It has a dehydration switching clutch and a brake for dehydration. A motor 7 is attached to the bottom of the outer tub 4, and the power of the motor 7 is transmitted via a motor pulley 8, a belt 9 and an impeller pulley 10. Reference numeral 11 denotes an anti-vibration mechanism that is suspended from the upper corner of the main body 1 by a support rod via a spring, and suspends and supports the washing tub 4.

The spin-drying washing machine having this structure has a vibration-proof mechanism for preventing horizontal and vertical vibrations of the laundry receiving tub 4 during spin-drying due to unevenness of the objects to be dehydrated.
The vibration is attenuated by 11 so that the vibration is not transmitted to the main body 1. However, with respect to the vibration at the time of starting dehydration, the vibration damping of the vibration damping mechanism 11 may not be sufficient for the vibration damping, so that the washing tub 4 may collide with the main body 1 or a safety switch (not shown). There was a case where the normal dehydration action was not performed by operating the engine to stop the operation.

In order to solve such a problem, the inventors have already proposed an anti-vibration device for a dehydration washing machine having a structure as shown in FIG. In FIG. 5, the members 1 to 11 are the same as those in FIG. 4, and therefore their explanations are omitted. Reference numeral 12 denotes an elastic body, one end of which is fixed to the laundry receiving tub 4 by a claw of the supporting member 13.
Reference numeral 14 denotes a sliding body, which is attached to the other end of the elastic body 12 by a claw. Reference numeral 17 denotes a flat plate-shaped sliding member fixed to the main body 1, and a cushioning member 16 is interposed between the sliding member 17 and the main body 1 to alleviate vibration transmission to the main body 1.

With this configuration, even if the material to be dehydrated is unevenly distributed during dehydration, the whirling vibration of the laundry receiving tub 4 at the time of dehydration activation is caused by the elastic body.
This is suppressed by the sliding frictional force between the sliding member 14 and the sliding plate 14 and the sliding member 17 to prevent the laundry receiving tub 4 from colliding with the main body 1 and reduce the vibration transmission to the main body 1.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, the structure of the conventional example already proposed has a remarkable action and effect as the vibration isolator of the washing and dehydrating machine, but the shake of the washing tub 4 When the circumference becomes large, the flat plate-shaped sliding member 17 fixed to the main body 1 via the cushioning member 16 cannot suppress the vibration, and the side surface of the main body 1 becomes sticky, the plate thickness of the main body 1 and the sliding member. There were problems such as the need to increase the plate thickness of 17.

The present invention solves such a problem, and provides a vibration isolation device for a dehydration washing machine, in which vibration during dehydration is small, and the weight of the main body and the sliding member is minimized to reduce the weight. That is the purpose.

Means for Solving the Problems The technical means of the present invention for achieving the above-mentioned object is to be suspended and supported in the main body of the spin-drying washing machine and a vibration damping mechanism for damping vertical vibration. A washing container, a compressible elastic body having a sliding member attached to one end thereof and a side wall of the washing container attached to the other end, and a sliding member interposed between the sliding member and the main body and elastically contacting the sliding member. A plurality of the sliding members are provided in a substantially L-shaped shape at opposite side wall corner portions of the main body,
In addition, the sliding members urged by the elastic member are arranged in contact with each other on both sides of the sliding member with the corners interposed therebetween.

Action With the above configuration, since the sliding member is substantially L-shaped, the two sliding parts influence each other to suppress whirling vibration of the washing tub, and the sliding member itself is reinforced. This can prevent the vibration transmission to the main body.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. The structure of the main part of the present invention is as shown in FIGS. 1 to 3, but the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals and the description thereof will be omitted.

In the figure, 12 is an elastic body, and is preferably formed of a compression spring or the like having a non-linear stress-strain characteristic.
Reference numeral 13 is a support member fixed to the washing tub 4, and one end of the elastic body 12 is attached by a claw. Reference numeral 14 denotes a sliding body, which is attached to one end of the elastic body 12 by a claw. 15 is a sliding member,
It has a substantially L shape, and the protrusion 15a provided at the upper end.
Thus, the suspension supporting member 1a of the anti-vibration mechanism provided at the upper corner of the main body 1 is fixed by screws or the like. Note that the protrusion 15a
It may be fixed to the main body 1 via the cushioning member 16 without providing. In any case, a plurality of sliding members 15 are fixed to the opposite side wall corners of the main body 1. A metal or resin material is used as the material of the sliding member 15.

Next, the operation of the configuration of this embodiment will be described.

When the article to be dehydrated is unevenly distributed in the washing / dehydrating tub 2 during dewatering, whirling of the washing tub 4 occurs, but between the sliding member 15 interposed between the washing tub 4 and the main body 1. As described above, the elastic body 12 and the sliding body 14 which are elastically contacted with each other act to suppress the whirling of the elastic body 12 and reduce the transmission of vibration to the main body 1.

At this time, the sliding member 15 is formed in a substantially L-shape at the side wall corners of the main body 1 which face each other, and the corners are in between.
By arranging the sliding bodies 14 biased by the elastic bodies 12 in pairs on both sides of the 15, one of the sliding bodies 14 is displaced outward with respect to whirling vibration, while the other is displaced inward. Will be displaced to. Therefore, the compressive force acts on the elastic body 12 corresponding to the sliding body 14 which is displaced inward.

As a result, it is possible to reduce the displacement of the sliding body 14 as compared with the case where the sliding members 15 are individually provided as flat plates.

Further, by making the sliding member 15 into a substantially L shape,
The strength of the flat end of the sliding member 15 is improved. Also, sliding members
Protrusion 15a is provided at the upper end near the corner of 15
If 5a is fixed to the suspension support member 1a provided at the upper corner of the main body 1, the vibration transmission to the main body 1 will be transmitted to the strongest part of the main body 1 and not directly to the side wall of the main body 1. Therefore, the side wall of the main body 1 is not sticky, and the main body 1
It is possible to reduce the thickness of the plate and reduce the weight.

EFFECTS OF THE INVENTION According to the present invention, by providing a substantially L-shaped sliding member at a side wall corner portion of a main body of a dewatering washing machine, there are two sliding points forming a substantially L-shaped sliding member. It is possible to suppress the whirling vibration of the laundry receiving tub due to the mutual influence of each other, and to prevent the vibration from being transmitted to the main body and prevent the deformation.

Furthermore, if the sliding member is fixed to the suspension support part of the anti-vibration mechanism provided above the corner of the main body, it is possible to prevent direct vibration transmission to the side wall of the main body, thus reducing deformation of the main body. Yes, the body plate thickness can be reduced. Therefore, it is possible to achieve an excellent effect such as weight reduction.
