Description

A cabinet's structure of the drum type washer}

The present invention relates to a drum washing machine in which the rotating shaft of the drum is disposed in a horizontal direction. In particular, a plurality of bent portions are formed in a cabinet forming the exterior of the washing machine, so that vibrations generated when the washing machine is operated are canceled to reduce vibration and noise. It relates to a cabinet structure of a drum washing machine to be able to perform a predetermined operation.

In general, a washing machine is a device that removes the contamination on clothing by electric power through a process of washing, rinsing, and dehydration. Among these washing machines, water, detergent and laundry were put inside the drum in which several protrusions were formed, and the laundry was raised by the protrusions by rotating at a low speed on the horizontal axis. It is common for the drying process to be included.

1 is a side sectional view showing a main part of a drum washing machine according to the prior art.

The drum washing machine according to the prior art is provided with a cabinet having an opening (1) formed on its front face, a tub (4) installed inside the opening (1) and washing water, and rotatably installed inside the tub (4). A drum (10) containing laundry and detergent, a motor (6) connected to the rotating shaft of the drum (10) and mounted on the rear of the tub (4), and the tub (4) are fixed to the inside of the cabinet. A suspension 8 is installed between the inner wall of the cabinet 2 and the outer wall of the tub 4 so as to be installed in a flowable manner.

Here, as shown in FIG. 1, the cabinet includes a cabinet body 2 in which both sides and a rear surface of the washing machine are integrally formed, and a base 40 disposed on the bottom of the cabinet body 2 to form a bottom surface of the washing machine. A front cover 30 disposed at the front of the cabinet body 2 to form the front of the washing machine, the front cover 30 having the opening 1 formed thereon, and a top cover disposed at the top of the cabinet body 2 to form the upper surface of the washing machine ( 35) is configured to include.

2 is a perspective view showing a cabinet body of a drum washing machine according to the prior art.

As shown in FIG. 2, both sides and the rear surface of the washing machine are integrally formed, and the planar shape is formed in a 'c' shape, and a rectangular service hole 2a is formed on the rear surface of the cabinet body 2. Is formed, the cover (not shown) is detachably installed in the service hole (2a), when the failure occurs in the drum 10 and the motor (6) installed inside the cabinet body (2), the cover is disassembled To conveniently perform the repair or replacement of the drum 10 and the motor (6).

In addition, a plurality of recesses 2b are formed on both sides of the cabinet body 2 to be recessed inward to improve the strength of the cabinet body 2.

However, the cabinet structure of the drum washing machine according to the prior art has a service hole portion 2a having a size to which the motor 6 can be detached from the rear of the cabinet main body 2, and is identical to both sides of the cabinet main body 2. Since a plurality of recesses 2b having a depth are formed, the strength of the cabinet body 2 is weakened by the service hole portion 2a formed on the rear surface of the cabinet body 2, and the driving force of the motor 6 causes the There is a problem that vibration and noise may be generated in the cabinet body 2.

In addition, the vibration generated when the drum 10 is driven is transmitted to the recess 2b in which the drum 10 and the tub 4 are supported in the recess 2b, along the cabinet body 2. There is a problem that the vibration can be transmitted throughout the washing machine.

The present invention has been made in order to solve the above problems of the prior art, by improving the structure of the back and both sides of the cabinet cover, the vibration generated by the driving of the motor and drum is attenuated, vibration and noise is reduced and stable operation It is an object of the present invention to provide a cabinet structure of a drum washing machine.
