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.

Conventional technology 2-7゛This type of dehydrating washing machine was developed, for example, in 1973-307
As shown in Publication No. 10, it had a structure as shown in FIG. That is, in the figure, 1 is the main body of the dehydrating washing machine, 2 is a washing and dehydrating tank in which a plurality of dehydrating holes 3 are formed in the inner peripheral wall, 4 is a laundry receiving tank in which the washing and dehydrating tank 2 is rotatably installed inside, Reference numeral 5 denotes an agitation blade provided at the center bottom of the washing and dewatering tank 2, and 6 a transmission mechanism, which incorporates a reduction gear for washing, a switching clutch for washing and dewatering, and a brake for dewatering. Reference numeral 7 denotes a motor attached to the bottom of the outer tank 4, and the power of this motor 7 is provided by a motor pulley 8 and a belt 9.
, is transmitted via the impeller pulley 10. Reference numeral 11 denotes a vibration damping mechanism which is suspended from the upper corner of the main body 1 by a support rod via a spring, and supports the washing tank 4 in a suspended manner.

In this dehydrating washing machine, the vibration isolating mechanism 11 attenuates horizontal and vertical vibrations of the washing tub 4 during dewatering due to unevenness of the objects to be dehydrated, so that the vibrations are not transmitted to the main body 1. However, the anti-vibration mechanism 1 prevents vibrations during startup of dehydration.
Friction damping in step 1 may result in insufficient vibration to prevent 3, which may cause the washing tub 4 to collide with the main body 1, or cause a safety switch (not shown) to be activated to stop operation and prevent normal operation. In some cases, proper dehydration was not achieved.

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 FIGS. 3 and 4. In Figures 3 and 4, 1 to 1
The members shown in FIG. 4 are the same as those shown in FIG. 4, so their explanation will be omitted. Reference numeral 12 denotes an elastic body, one end of which is fixed to the washing tank 4 by a claw of a support 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 15 denotes a flat sliding member fixed to the main body 1, and a buffer member 16 is interposed between the sliding member 15 and the main body 1 to reduce vibration transmission to the main body 1.

With this configuration, even if the objects to be dehydrated are unevenly distributed during dehydration, the whirling vibration of the laundry receiving tub 4 at the time of starting dehydration can be suppressed by the sliding friction force between the elastic body 12 and the sliding plate 14 and the sliding member 15. This prevents the washing tub 4 from colliding with the main body 1 and reduces vibration transmission to the main body 1.

Problems to be Solved by the Invention As mentioned above, the structure that has already been proposed has a remarkable action and effect as a vibration isolating device for a dehydrating washing machine. The four minimum gaps are:
The main body 1 has a square planar shape, so depending on the installation location, there are restrictions in the front and back or left and right directions, making installation difficult. , a vibration-proofing dehydrating washing machine that solves these problems and reduces vibration during dehydration, and also minimizes the width of either the front or back or left and right sides of the main body to improve installation ease. The purpose is to provide a device.

Means for Solving the Problems The technical means of the present invention for achieving the above object consists of an elastic body having a sliding body attached to one end and the other end attached to the side wall of the washing tub, and the sliding body and the main body. and a sliding member interposed therebetween, with which the sliding member makes elastic contact, and the elastic members are comprised of at least two pairs, and the entire length or elasticity is adjusted between each pair of elastic members so that the washing tank can move in an elliptical manner during dewatering. In addition to having different coefficients, the minimum gap between the main body and the laundry tub is set to be wider in the dog direction of the whirling amplitude of the laundry tub than in other directions.

Effect With the above configuration, since the characteristics of each pair of elastic bodies of at least two pairs of elastic bodies are different, the whirling vibration of the washing tub at the initial stage of spin-starting becomes an elliptic motion, and the minimum gap between the main body and the washing tub is By allowing large swings in the wide direction and suppressing swings in the narrow directions, the width of one side of the main body can be minimized, preventing vibrations from being transmitted to the main body, and improving the installation ease of the main body. be able to.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings. The configuration of the main part of the present invention is shown in FIG. 1, but the same parts as in FIGS. 2 to 4 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In the figure, reference numeral 12 denotes an elastic body, preferably made of a compression spring or the like having non-linear stress 6 Benault strain characteristics, and each pair of 12a and 12b is made of a material having different overall length and elastic modulus. ing.

Reference numeral 13 denotes a support member fixed to the washing tank 4, and one end of the elastic body 12a or 12b is attached to the claw.

14 is a sliding body, which has a claw elastic body 12a or 12b.
is installed at one end of the

Reference numeral 15 denotes a sliding member, which has an abbreviated shape and is fixed to the suspension support member 1a of the vibration isolation mechanism 11 provided at the upper corner of the main body 1 by means of a protruding portion 15a provided at the upper end by screwing or the like. are doing.

Note that it may be fixed to the main body 1 via the buffer member 16 without providing the protrusion 16a. In any case, a plurality of sliding members 16 are fixed to opposing side wall corners of the main body 11. Sliding body 14. As the material of the sliding member 15, metal or resin material is used.

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

When the items to be dehydrated are unevenly distributed in the washing/dehydrating tub 2 during dewatering, the washing tub 4 whirls around, but there is an elastic contact between the washing tub 4 and the sliding member 15. As already explained, the interposed elastic bodies 12a and 12b and the sliding body 14 act to suppress the whirling of the body and to reduce the transmission of vibrations to the main body 1.

At this time, the elastic bodies 12a and 12b have different lengths or elastic coefficients, and if the elastic bodies have the same elastic coefficient in the direction t1 of the widest minimum gap between the main body 1 and the washing tub 4, the elastic bodies 12a and 12b have different lengths or elastic coefficients. By providing an elastic body with a low coefficient and providing an opposite elastic body in the other direction 4, it is possible to cause the laundry receiving tub 4 to swing largely in the direction t1 where the minimum gap is wide in response to the whirling vibration of the washing tub 4 at the initial stage of dehydration startup. become. That is, the vibration amplitude of the laundry receiving tub 4 at the initial stage of activation follows an elliptical orbit. In the direction 4 where the minimum gap between the main body 1 and the washing tank 4 is narrow, even if the elastic body 12a has the same elastic modulus, the set length is short, so the elastic modulus is high and movement is suppressed. In addition, if a material with a high elastic modulus is installed, the washing tank 4
The whirling can be reliably suppressed. Therefore, even if the minimum gap 4 between the main body 1 and the washing tank 4 is minimized, it is possible to prevent a collision with the main body 1 at the time of startup. As dewatering progresses further and the washing/dehydrating tub 2 reaches high speed rotation, the vibration amplitude of the washing tub 4 becomes smaller than when it is started, so there is no risk of collision with the main body 1, and the minimum gap in all directions is narrowed. Since the restraining force in at least one direction can be made smaller than in the case where the vibration is transmitted to the main body 1 during high-speed rotation, it is possible to suppress the transmission of vibration to the main body 1 during high-speed rotation.

Effects of the Invention The present invention provides at least two pairs of elastic bodies that are in elastic contact between the laundry basin and the main body of a dehydrating washing machine, and each pair of elastic bodies is made to have a different overall length or elastic modulus to allocate the laundry basin. By changing the force, the whirling amplitude of the laundry tub at the initial stage of spin-starting is made into an elliptical motion, and the minimum gap between the main body and the laundry tub is set so that the dog direction of the whirling amplitude of the laundry tub is made wider than other directions. This improves the degree of freedom during installation and reduces vibration transmission to the main body9.
7. It is something that can be done.
