Description

Low noise washing machine

The present invention relates to a low noise washing machine, and more particularly, to a low noise washing machine capable of quiet operation by absorbing vibration generated by a driving device attached to a lower portion of a water tank.

In general, most homes are equipped with a washing machine so that a large amount of various laundry can be washed quickly and easily. Such a general washing machine basically has a water tank fixedly installed in an outer case of the washing machine, and at a predetermined interval inside the water tank. The water tank is fixedly installed so as to be spaced apart from each other and is rotatable at a high speed, and a pulsator is rotatably housed in the lower part of the washing tank.

Referring to the operation of the washing machine schematically, when the washing water is first supplied to the washing tank, the washing water is filled not only in the washing tank, the reservoir tank, between the washing tank and the reservoir tank, but also in the space between the lower portion of the washing tank and the reservoir tank. In the subsequent washing operation, the pulsator rotates to the left and right, and by rotating the pulsator, the back water is generated in the washing tank, and the washing is performed. At the same time, dehydration is performed, and the dewatered wash water is discharged to the reservoir through a hole formed in the washing tank, after which the washing water is drained to the outside through a drain hole formed at the bottom of the reservoir to perform washing. will be.

That is, referring to this washing machine with reference to FIG. 1, a water storage tank 14 for storing water supplied from the water supply valve 12 is installed in the cabinet 10, and a washing tank 14 is installed in the water storage tank 14. 16 is rotatably installed, and a plurality of holes 18a for drilling water in and out are drilled in the washing tank 16.

On the other hand, the reservoir 14 is suspended on the inner upper part of the cabinet 10 by the suspension device 18, and the suspension device 18 has a long arm 18a, and the upper end of the arm 18a. Is suspended from the fixed piece 10a formed in the upper part of the cabinet 10, and the lower end of the arm 18a is caught and held by the support piece 14a formed below the outer peripheral surface of the reservoir 14. As shown in FIG. Moreover, the spring 18b is wrapped by the housing 18c at the lower end of the arm 18a. The suspension device 18 installed as described above serves to cushion the vibration and shaking of the reservoir 14 generated during washing and dehydration to balance the reservoir 14 and prevent noise.

In addition, a base 20 is installed at a lower portion of the water storage tank 14, and a gear device 24 is provided on the lower surface of the base 20 to reduce and interrupt the motor 22 and the driving force of the motor 22. Are installed respectively. The gear device 24 has a first drive shaft 24a for rotating the pulsator 26 located at the bottom of the washing tub 16 and a second drive shaft 24b for rotating the washing tub 16. . In addition, the gear device 24 is not shown to control the driving force so that a combination of a plurality of gears, for example, planetary gears and a ring gear, and rotation of one of the first and second drive shafts 24a and 24b are made. It consists of a clutch, and the 1st drive shaft 24a is wrapped by the 2nd drive shaft 24b.

Therefore, when the user sets the washing function desired by the user, the pulsator 26 is rotated by the first drive shaft 24a of the gear device 24 which transmits the driving force of the motor 22 as described above. Water is generated by the rotation of the eater 26 to wash the laundry. When the washing tub 16 is rotated by the second drive shaft 24b of the gear device 24, the water is drained through the holes 16a of the washing tub 16 while being drained to the reservoir 14.

However, in the conventional washing machine as described above, although the suspension device 18 described above is installed, the suspension device carries out some of the vibrations and fluctuations generated by the drive device through the arm, that is, the cabinet ( 10), the vibration and shaking of the water tank 14 generated during washing and dehydration are severely generated, and thus there is a problem of lowering the quiet operation, and the driving and pulsator of the motor 22 and the gear device 24 are reduced. Vibration and shaking of the washing tub 16 is generated by vibrations and shocks generated by the rotation of the 26, and in response to the vibration and shaking of the washing tub 16, vibration and shaking are also generated in the water tank 14, thereby resonating sound. There was a problem that the severe noise occurs.

In addition, although some of the vibrations and oscillations of the reservoir 14 and the washing tank 16 may be buffered by the suspension device 18, for example, due to the inability to completely buffer the vibrations and oscillations generated by the drive system, When rocking and vibration occurs, the upper part of the washing tank 16 hits the upper part of the water storage tank 14, and there is a problem in that a quiet operation is not performed because a large impact and noise are generated.

The present invention is devised to solve the problems as described above, an object of the present invention is to provide a low noise washing machine that can prevent the noise by absorbing the vibration generated by the drive of the drive device.

Another object of the present invention is to provide a low noise washing machine capable of quiet operation by absorbing and buffering in a water tank so that vibrations and fluctuations generated by a driving device during washing are not transmitted to the outside through a suspension device.
