Description

Water supply of washing machine

The present invention relates to a water supply device for a washing machine, and more particularly, to improve the structure of the water supply device connecting means for supplying the washing water to the washing machine. Relates to a device.

1 is a cross-sectional view of a conventional washing machine, in which a main body 1 formed in a rectangular shape and a water tank 2 in which a certain amount of washing water is dehydrated are suspended from the main body 1 by a hook rod 7. .

A water supply pipe 10a for supplying wash water and a water supply valve 10 for operating the opening and closing of the water supply pipe 10a are formed at an upper portion of the main body 1, and the water supply pipe 10a is disposed outside the main body 1. One side of is connected to the water pipe (14).

In addition, the tub 2 is installed in a state in which the cylindrical washing tub 3 is rotatable therein, and the tub 3 is provided with a myriad of holes 3a penetrating the side wall, and is supplied into the tub 3. The washing water flows to the water tank 2 to match the water level of the washing water tank 3 and the water tank 2, and these holes 3a discharge the washing water generated from the wet clothes during the dewatering process toward the water tank 2 .

On the other hand, the stirring blade (4) is installed on the inner bottom of the washing tank (3) in a rotatable state, and the stirring blade (4) is reversely rotated in the washing process, and the wash water supplied into the washing tank (3) Stir to generate a vortex.

In addition, the power switching means 6 which is rotated by the motor 5 is installed in the center of the bottom face of the water tank 2. A washing shaft 6a and a dewatering shaft 6b are formed at an upper portion of the power switching means 6, and the washing shaft 6a is combined with the stirring blade 4 and the dewatering shaft 6b is formed of the washing tank 3. It is coupled to the bottom.

In addition, a filter 9a for filtering foreign substances of the washing water is installed at a lower portion of the main body 1 and a watering pipe 8 for spraying the washing water into the washing tank 3 is formed at the upper end of the water tank 2. do. In addition, the bottom surface of the water tank 2 and the filter 9a are connected to each other through a hose 9b, and a pump 9 is installed between the filter 9a and the water pipe 8, and behind the pump 9 A drain valve 9c is installed to drain the wash water when dewatering.

In the conventional washing machine configured as described above, when the laundry is contained in the washing tank 3 and the water supply valve 10 is opened, the water supplied from the water pipe 14 is introduced into the washing tank 3 through the water supply pipe 10a to supply the washing water. Washing is in progress.

When the washing process starts, the motor 5 periodically rotates forward and backward, and its rotational force is transmitted to the power switching means 6, and then the speed change is decelerated by the power switching means 6, and then the forward and reverse rotational power is the washing shaft 6a. It is passed through the stirring blade (4) through.

At this time, when the stirring blade 4 is reversely rotated, strong vortices are generated in the wash water, and washing proceeds while the clothes are rubbed with each other by the rotating water flow in this process.

In addition, during the washing process, a part of the washing water is pumped toward the sprinkling pipe 8 above the washing tank 3, and the pumped washing water is sprayed into the washing tank 3. That is, when the pump 9 is operated, the wash water is pumped toward the sprinkling pipe 8 through the hose 9b connected to the bottom of the water tank 2, and the pumped wash water is sprayed into the washing tank 3, thereby improving washability.

After the washing is completed, the washing water is drained through the drain valve 9c, and then dewatering proceeds. At this time, when the motor 5 rotates in one direction at high speed during the dehydration process, the washing shaft 6a and the washing shaft 6a are removed by the power switching means 6. Shrinkage (6b) is rotated at a high speed with the washing tank 3 is rotated at a high speed to completely remove the water in the laundry.

In the conventional washing machine operated as described above, the water supply device has a male screw portion 11d formed at a lower end thereof and a bolt hole 11c formed at four sides of the upper end thereof as shown in FIG. 2 to form a bolt 11b at the water pipe 14. A holder 11 to be fixed, a packing 12 to be fitted inside the holder 11, and an insertion part 13b is formed at a lower end thereof, and a connection pipe fixing holder 13a is formed at an outer side thereof so that an upper end thereof is formed in the holder ( 11) the connection pipe 13 is coupled to the lower end, and a groove 10b is formed on the inner circumferential surface and the water supply pipe 10a to which the insertion portion 13b of the lower end of the connection pipe 13 is fitted and fixed.

In addition, a locking plate 11a is fitted to the inner circumferential surface of the holder 11 so that the packing 12 is caught, and the connection pipe fixing holder 13a corresponds to the male screw portion 11d at the lower end of the holder 11 on the inner circumferential surface. The female screw portion 13c is formed as much as possible.

A rotary protrusion 13d is formed on the outer circumferential surface of the insertion portion 13b and fitted into the groove 10b of the inner circumferential surface of the water supply pipe 10a.

In the water supply device of the conventional washing machine configured as described above, the locking plate 11a is fitted into the interior of the holder 11, and the packing 12 is fitted through the bottom thereof.

Thereafter, the upper end of the holder 11 is fitted into the water pipe 14, and the bolt 11b is inserted into and fastened to the bolt hole 11c formed on all sides, and then the side of the water pipe 14 is compressed.

After the coupling is completed, the connecting pipe 13 is installed. In this case, the male screw part 13c of the connecting pipe fixing holder 13a formed at the outer end of the holder 11 is connected to the male screw part 11d and the connecting pipe 13. Tighten by screwing.

Therefore, the packing 12 placed between the locking plate 11a and the connection pipe 13 inside the holder 11 is compressed to prevent water leakage.

Thereafter, the water supply pipe (10a) is coupled to the insertion portion (13b) of the lower end of the connecting pipe (13). At this time, the rotation protrusion 13d of the insertion portion 13b is caught in the groove 10b of the inner circumferential surface of the water supply pipe 10a to facilitate detachment and improve the coupling force when engaged.

The water supply device of the conventional washing machine as described above has a problem in that water is leaked into a gap between the locking plate and the packing, which are particularly vulnerable to bonding, when the number of parts is complicated and the assembly process is complicated.

The present invention was created in view of the above problems, and improved the structure of the water supply device connecting means for supplying the washing water to the washing machine. The purpose is to provide.
