Description

Reservoir installation structure of washing machine

The present invention relates to a washing machine, and more particularly, to a reservoir installation structure of a washing machine for suspending and installing the reservoir inside the cabinet.

In general, a washing machine is a device that automatically performs a series of washing, rinsing, and dehydration by putting laundry, water, and an appropriate amount of detergent in a washing tank, and giving the laundry a shock caused by mechanical water flow. .

Referring to an example of such a washing machine based on FIG. 1, a water storage tank 14 for storing water supplied from the water supply valve 12 is installed in the cabinet 10, and the washing tank 16 is installed inside the water storage tank 14. ) Is rotatably installed, and a plurality of holes 18a are formed in the washing tank 16.

On the other hand, the reservoir 14 is installed by hanging the interior of the cabinet 10 by the suspension device 18, the suspension device 18 has a hook rod (18a), the upper end of the hook rod (18a) the cabinet It is held on the upper inner surface of the (10), the lower end of the hook rod (18a) is held by the hook piece (14a) formed on the lower outer peripheral surface of the reservoir 14, the spring (18b) at the lower end of the hook rod (18a) ) Is wrapped by the housing 18c. The suspension device 18 buffers 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, and the pulsator 26 Water is generated by the rotation of the laundry to perform 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, the vibration and shaking of the reservoir 14 generated during washing and dehydration are severely generated, which causes a problem of lowering reliability. For example, vibrations and shakes of the washing tub 16 are generated by vibrations and shocks generated by the driving of the motor 22 and the gear device 24 and rotation of the pulsator 26, and the vibration of the washing tub 16 and In response to shaking, vibration and shaking are also generated in the reservoir 14 to generate a resonance sound.

The vibration and shaking of the water tank 14 and the washing tank 16 are buffered by the suspension device 18, but since the hook rod 18a is held under the outer circumferential surface of the water tank 14, the water tank 14 When the shaking of the washing tub 16 is greater than the shaking of the washing tank 16, the upper part of the washing tank 16 hits the upper part of the washing tank 16, and the impact and noise are greatly generated. This is detected as an abnormal state of the washing machine by a sensor (not shown) to stop the driving of the motor 22 has a problem that the washing is temporarily stopped.

On the other hand, when dehydration is performed by the rotation of the washing tub 16, the washing tub 16 may perform an eccentric rotational movement about the second drive shaft 24b of the gear device 24, and the washing tank 16 is eccentric. The rotational motion causes the shake of the reservoir 14 to be large. At this time, when the hook rod 18a of the reservoir 14 and the suspension device 18 move in opposite directions without being shaken in the same direction, the lower end of the hook rod 18a collides with the reservoir 14 to generate a large impact and noise. In severe cases, there was a problem in which the reservoir 14 and the suspension device 18 were damaged. In addition, since the lower end of the hook rod 18a is to be held by the hook piece 14a of the reservoir 14, the installation of the reservoir 14 becomes difficult and there is a problem that the assemblability deteriorates.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is to install the reservoir of the washing machine so that the reservoir is stably installed to prevent the occurrence of vibration, shock, noise, etc. to improve reliability. To provide structure.

Another object of the present invention is to provide a water tank installation structure of a washing machine to facilitate the installation of the water tank to improve the assembly.
