Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a vibration isolating device for a dehydrating washing machine that washes and dehydrates clothes and the like.

2. Description of the Related Art A conventional dehydrating washing machine has a structure as shown in FIG. 5, for example. In the figure, 1 is the main body of the dehydrating washing machine, 2
4 is a washing and dehydration tank with a plurality of dehydration holes 3 formed in the peripheral wall;
6 is a washing tank with a washing and dehydrating tank 2 rotatably installed therein; 6 is a stirring blade installed at the center inner bottom of the washing and dehydrating tank 2;
The transmission mechanism includes a reduction gear for washing, a switching clutch for washing and spin-drying, and a brake for spin-drying. 7
is a motor attached to the bottom of the washing tank 4, and the power of this motor 7 is transmitted to the transmission mechanism 6 through a motor pulley 8, a belt 9, and an impeller pulley 1o. Reference numeral 11 denotes a vibration isolating mechanism suspended from the main body 1, which supports the washing tank 4 on the main body 1 in an anti-vibration manner. A reinforcing cover 12 is attached to the upper part of the washing tub 4 to reinforce the washing tub 4.

The dehydrating washing machine with this configuration uses a total vibration isolation mechanism 11 to attenuate vibrations in the horizontal and vertical directions of the washing tank 4 at the time of starting dehydration due to unevenness of the objects to be dehydrated. However, since the friction damping provided by the vibration isolation mechanism 11 alone is insufficient for horizontal movement, if the washing tub 4 collides with the main body 1, the safety switch (not shown) Even if the machine was turned on and then stopped, the normal dehydration process sometimes did not occur.

In order to solve this problem, the inventors have already proposed a vibration isolating device for a dehydrating washing machine having a structure as shown in FIG. In FIG. 6, the same members as those in the conventional example are given the same reference numerals and their explanations will be omitted. Reference numeral 13 denotes a mounting portion for the elastic body 14, which is provided at a plurality of locations facing each surface of the main body 1;
A claw portion is formed and integrally formed with the washing tank 4.

Reference numeral 13 denotes a plurality of elastic bodies made of coil springs or the like, one end of which is fixed to the mounting portion 13, and the other end of which is attached to the sliding body 15.
is installed. This sliding body 16 is slidably and elastically contacted to the inner wall of the main body 1.

With this configuration, even if the objects to be dehydrated are unevenly distributed during dehydration, the swinging vibration of the washing tray N4 at the time of starting dehydration is suppressed by the reaction force of the elastic body 14 and the sliding friction force between the sliding body 16 and the main body 1. This prevents the washing tub 4 from colliding with the main body 1, and allows normal dewatering to start.

Problems to be Solved by the Invention As mentioned above, the structure already proposed has a remarkable action and effect as a vibration isolator for a dehydrating washing machine. The elastic body 14 is installed in a complicated work involving twisting Dt in the narrow space between the parts 13 and 4.
Since it had to be fixed at the same time, productivity was adversely affected. Further, when the mounting portion 13 is integrally molded into the washing tank 4, the mold becomes complicated because the shape is claw-like. Furthermore, the method of attaching the part 13 as a separate part and fixing it to the washing tank 4 also requires melt layer or adhesive work, which reduces productivity. To provide a simple vibration isolating device having a highly productive structure, which solves all the problems, attenuates the swinging vibration of a washing tub at the start of dewatering, allows smooth start of dehydration, and is highly productive.

Means for Solving the Problems In order to achieve the above object, the vibration isolating device for a dehydrating washing machine of the present invention includes a main body, a vibration isolating mechanism suspended in the main body, and formed on an upper outer wall surface. A laundry receptacle having a mounting part, a sliding body that is in elastic contact between an inner wall of the main body and an outer wall of the laundry receptacle, a sliding body sliding on the inner wall of the main body at one end, and an elastic body stopping at the other end. an elastic body to which an insert body is fixed, which is made up of an indigenous part to be attached to the washing tank, and an insert part to be inserted into the mounting part formed in the washing tub; It is constructed with a reinforcing cover having an identification part fixed to the holder, and is intended to facilitate assembly work and improve productivity.

Function: With this technical means, the elastic body, sliding body, and insert body can be completed as a single assembled part, and after the main body is equipped with a washing tub, a washing tank, a vibration isolation mechanism, etc., and assembled, the above-mentioned assembled parts are assembled. The elastic body is inserted into and attached to the attachment part of the laundry receptacle, and the elastic body is interposed in elastic contact between the main body and the laundry receptacle, and the reinforcing cover is attached to the laundry receptacle so that the insert body can be fixedly attached to the laundry receptacle. This makes it easy to assemble the dehydrating washing machine and improves productivity.
