Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum type washing machine which is used in general households, in which clothes are washed by rolling in a drum and dehydration is carried out by high speed rotation of the drum.

[0002]

2. Description of the Related Art A conventional drum type washing machine having a structure as shown in FIG. 4 is known. Hereinafter, referring to FIG. 4, reference numeral 1 denotes a washing machine body, and the washing machine body 1
A water tank 3 supported by a spring 2 therein, and a drum 6 having an opening on the front surface, a rotary shaft 4 on the rear surface, and a water passage hole 5 on the side surface.
Is provided. The rotating shaft 4 is supported by a bearing 7 provided on the rear surface of the water tank 3. Also, the rotating shaft 4
A pulley 10 is attached to an end portion of the belt, and a belt 9 is hung between the pulley 10 and a pulley 8b attached to a shaft 8a of the washing motor 8. 11 has one end in the aquarium 3,
The other end is a damper supported by the washing machine body 1. A bellows 12 is provided on the front surface of the water tub 3 for maintaining water tightness with the washing machine body 1, and is fitted with a tapered lid 13. Further, the washing machine body 1 includes a body 14 and a top plate.
The front plate 16, the back plate 17, and the bottom plate 18 are fixed to each other by screws 19.

[0003]

With such a structure, when the clothes are biased toward the lower part of the drum 6 when washing and plowing are finished and dehydration is to be performed.
Will be rotated. At this time, the water tank 3 vibrates due to the eccentric load due to the clothes, and the vibration of the water tank 3 is transmitted to the body 14 via the spring 2 and the damper 11 and vibrates the body 14. The vibration of the body 14 is transmitted to the top plate 15, the front plate 16, the back plate 17, and the bottom plate 18 attached by the screws 19. As a result, the vibration spreads over the entire area, which is one of the causes of noise expansion. Further, there is a problem that noise inside the body 14 leaks to the outside through a gap between the fitting portions of these components.

The present invention has been made to solve such a problem, and an object of the present invention is to prevent the vibration of the body from being transmitted to the components and to prevent the noise inside the body from leaking to the outside.

[0005]

In order to solve this problem, the present invention has a water tank in which a main body of a washing machine is supported by a spring and is provided with a bearing, and a rotating shaft supported by the bearing. A drum that rotates in the water tank at the center, and a pulley that is attached to the rotating shaft and is arranged outside the water tank,
In a drum type washing machine including a belt hung between the pulley and a pulley of a washing motor, the washing machine body is composed of a body, a top plate, a front plate, a back plate, and a bottom plate, and these components The vibration absorbing material is interposed in each of the joint portions.

[0006]

With the above-described structure, the drum type washing machine of the present invention has the structure that the vibration of the body during dehydration is absorbed by the vibration absorbing material,
Prevents vibration from being transmitted to the front, back and bottom plates. Further, since the connecting portion of these components is sealed by the vibration absorbing material, the noise inside the body is less likely to leak to the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, 20 is a washing machine main body
21 is a water tank suspended by a plurality of springs 22 in a semi-constrained manner. Inside the water tank 20, a drum supported by a rotary shaft 23, a side water passage hole 24 and a front opening 25 are provided. Has 26. Further, 27 is a damper, one end of which is supported on the bottom of the water tank 20 and the other end of which is supported on the main body 21 of the washing machine. Further, the rotating shaft 23 of the drum 26 is supported by a bearing 28, and a drum pulley 29 is attached to the tip of the rotating shaft 23 protruding from the bearing 28, and 30 is attached to the drum pulley 29 and a shaft 32 of a washing motor 31. The belt hung between the motor pulley 33 and the motor pulley 33. 34 is a clothing slot
It is a lid that opens and closes 35. 36 is a bellows having one end fixed to the water tank 20 and the other end fixed to the washing machine main body 21. Further, the washing machine body 21 includes a body 37, a top plate 38, a front plate 39, a back plate 40, and a bottom plate.
It is composed of 41, the top plate 38, the front plate to the body 37
When tightening the screws 39, the back plate 40, and the bottom plate 41 with the screws 43, between the body 37 and the top plate 38, between the body 37 and the front plate 39, between the body 37 and the back plate 40, between the body 37 and the bottom plate 41. A vibration-absorbing material 42 such as a rubber sheet is interposed between and.

Next, the operation of the above configuration will be described. When trying to dehydrate after washing and rinsing,
The drum 26 is rotated with the clothes biased to the lower part of the drum 26. At this time, the water tank 20 vibrates due to the eccentric load due to the clothes, and the vibration of the water tank 20 is transmitted to the body 37 via the spring 22 and the damper 27 and vibrates the body 37. Here, the vibration of the body 37 is absorbed by the vibration absorbing material 42 and is less likely to be transmitted to the top plate 38, the front plate 39, the back plate 40, and the bottom plate 41, so that the vibration is spread to the whole and noise expansion can be prevented. Furthermore, since the vibration absorbing member 42 eliminates the gap between the fitting portions of these components, noise inside the body 37 is less likely to leak to the outside.

[0009]

According to the drum type washing machine of the present invention, the vibration of the body at the time of dehydration is absorbed by the vibration absorbing material due to the above constitution.
The transmission to the top plate, front plate, back plate and bottom plate is suppressed, so that the vibration is not spread and a large noise is not generated. Further, since the gap between the fitting portions of these constituent parts is sealed by the vibration absorbing material, the noise inside the body is less likely to leak to the outside, and it is possible to provide a drum type washing machine with quiet noise.
