Description

Washing water circulator in a direct type washer

The present invention relates to a direct-type washing machine, and in particular, the washing water for washing the laundry in the washing tank is supplied to the guide hole of the stirring body formed integrally with the washing tank and the through hole of the insulator, and then passed between the cylindrical rib of the hub and the stirring body by passing through the hub. At the same time, the washing water circulated to the bottom of the washing tank is also supplied to the circulation hole of the stirring body by the pumping rib formed in the hub to continuously supply the washing water to the washing tank. The present invention relates to a washing water circulation system of a direct type washing machine that can improve efficiency and washing efficiency, and can simplify the assembly process and prevent frequent breakdowns and facilitate maintenance.

The washing water circulation structure of a conventional washing machine is shown in FIGS. 1 and 2.

That is, the conventional washing water circulation structure of the washing machine 1 is mounted to the inside of the washing machine 1 to wash the laundry by the operation of rinsing and dehydrating the laundry (2) and coupled to the bottom surface of the washing tank (2) Washing wing 4 is rotated by the drive shaft (7) to impart a tapping effect to the laundry, and the pumping for recycling the wash water formed at the bottom of the washing wing (4) collected in the bottom surface of the washing tank (2) Guide passages (3) formed in the cover (10) for supplying the wash water to the fluid balancer (12) by the pumping operation of the ribs (5) and the pumping ribs (5), and guides to the guide passage (3) Fluid filtering to filter the discharge port 8 formed in the fluid balancer 12 for resupplying the wash water into the washing tank 2 and the lint and foreign matter mixed in the wash water discharged to the discharge port 8. Filter frame 9 having filter 11 coupled to insertion passage 6 of book 12 is constructed. It has a comparative configuration.

Referring to the effects of the conventional configuration as described above are as follows.

First, when the laundry is put into the washing tank 2 of the washing machine 1 and the start button is pressed, the water supply is made first and then the washing blade 4 of the drive shaft 7 connected to the motor and the clutch is rotated to wash and wash the laundry. .

In addition, the washing water collected at the bottom of the washing tank 2 by the rotation of the washing blade 4 is pumped by the pumping rib 5 of the washing blade 4.

In addition, by the pumping action of the pumping rib 5, the washing water is supplied to the guide passage (3) formed by the cover 10 while being discharged to the discharge port (8) formed in the fluid balancer (12) 2) to re-supply the wash water.

At this time, since the filter 11 coupled to the filter frame 9 is blocked in the discharge port 8, the washing water discharged from the discharge port 8 passes through the filter 11, and the lint and the foreign matter mixed in the washing water, etc. Will be filtered.

Therefore, the washing water filtered by the filter 11 is supplied back to the washing tank 2 to continue the washing.

However, the circulation configuration of the wash water of the conventional washing machine as described above is a very complicated configuration.

That is, the cover 10 should be provided at one side of the washing tank 2 to guide the washing water pumped from the pumping rib 5 of the washing blade 4 to the fluid balancer 12.

Then, the fixing means for fixing the cover 10 to the washing tank 2 should be provided.

In addition, the structure of the fluid balancer 12 should be changed to allow the cover 101 to be coupled to the upper portion of the cover 10.

Then, a discharge port 8 for supplying the washing water supplied to the cover 10 into the washing tank 2 should be formed at one side of the fluid balancer 12.

In particular, the discharge port (8) of the filter means for coupling the filter (11) for filtering the lint mixed in the wash water should be applied.

As described above, in order to circulate the washing water, very many parts are required, so that the number of assembly labor and the use of raw materials are increased.

In addition, since the washing water must be pumped up to the upper end of the washing tank 2 by the rotational force of the washing blade 4, the washing blade 4 has a significant load on the mill motor.

Therefore, the capacity of the motor should be increased and used, and considerable effort should be paid to the strength of the washing blade 4.

In addition, due to the above complicated configuration, frequent failures occur and maintenance is not easy.

In particular, since the washing machine 1 is always filled with the washing water in the guide passage 3 of the cover 10 during the washing, the standard water level in the washing tank 2 is lowered, thereby lowering the washing performance.

Therefore, the washing tank 2 has to be supplied as much as the amount necessary to achieve a standard water level, so that a lot of washing water is used and there is also a serious waste of water.

The purpose of the present invention to solve and solve such a conventional problem,

By circulating the wash water more efficiently, the washing performance can be improved, and the circulation can be performed without disturbing each part by the smooth circulation of the wash water, and the simple configuration prevents frequent failure and convenience of maintenance. Serve the purpose of obtaining it.

In order to achieve the above object, the present invention,

Since the wash water flows out to the center of the stirring body integrally coupled to the washing tank and is circulated as it is re-supplied to the periphery of the stirring body, a shorter circulation path of the washing water can improve washing efficiency and prevent waste of water. The simple combination of the stirring body and the insulator and the hub allows to achieve a more robust wash water circulation system and at the same time reduce the assembly labor, thereby achieving the object of the present invention.
