Description

Vertical Water Flow Pulsator

The present invention relates to a vertical water flow pulsator, and more particularly, to a vertical water flow pulsator to form a vertical water flow path to generate a vertical water flow in the center of the pulsator to enhance the washing force.

In general, the washing machine is provided with a reservoir (2) for storing the washing water in the outer box (1), as shown in Figure 1, the drive bottom (3) and the reduction gear assembly (4) in the outer lower portion of the reservoir (2) ), The reduction gear assembly (4) is designed to receive power from the drive motor (3) by a belt.

A tub flange 5 is attached to the lower part of the washing tub 7 to form an integrated body. The washing tub 7 is supported by the central portion of the tub flange 5 being connected to the shaft of the reduction gear assembly 4. The shaft of the deceleration ear assembly 4 extends into the tub 7 through the tub flange 5 and is coupled to the pulsator 6.

The reduction gear assembly 4 may rotate only the pulsator 6 when the pulsator 6 and the washing tank 7 are in the washing stroke, and simultaneously rotate the washing tank 7 and the pulsator 6 in the dehydrating stroke. It is designed to be possible.

An upper plate including a control unit 8, a door 9, and an electrical equipment room 10 is coupled to an upper part of the washing machine outer box 1, and the control unit 8 adjusts washing water and time with respect to the washing administration. The electrical equipment compartment 10 includes electrical components and a water supply valve.

In the conventional washing machine, by inputting the washing stroke order to the control unit 8, the water supply valve in the electric compartment 10 is opened and the washing water is introduced into the water storage tank 2 according to the input order.

When the wash water reaches the set level of the control unit 8, the water supply valve is locked and the pulsator 6 rotates clockwise and counterclockwise for washing or rinsing.

After the end of the stroke, although not shown, the drain valve is opened and the washing water is discharged out of the washing machine in the water reservoir 2. After such a sequential stroke is repeated the number of times set in the controller 8, the washing tank 7 and the pulsator 6 are rotated together and the washing is finished.

In the washing or rinsing process, the pulsator 6 generates a vortex-like water stream to wash or rinse. Such a conventional pulsator 6 generates only a vortex-type water stream so that the laundry is not sufficiently rubbed. It does not fall well and the laundry is entangled, so more washing time or more detergent is required, which does not have a good effect on laundry.

Therefore, the object of the present invention is to solve the above-mentioned shortcomings, to equip the laundry without the tangling of the laundry without the cost increase, such as installing another additional device by mounting a pulsator forming a vertical water flow path It is to provide a vertical water flow pulsator that allows better washing.

A feature of the present invention for achieving the above object is to pulsator the rotation of the vertical water flow forming pulsator to the water flow wing formed upper plate and shaft to draw the washing water into the vertical water flow forming pulsator to form a vertical water flow A water inlet formed by dividing the lower plate formed with a locking groove so that the water does not go undesirably, the water flow outlet formed on the upper plate so that the washing water introduced into the vertical water flow forming pulsator becomes a vertical water flow so that the water flows out of the vertical water flow forming pulsator; And there is a vertical water flow path formed between the upper plate and the lower plate and the vertical water flow forming pulsator formed integrally so that the wash water flows into the water inlet can be discharged to the water flow outlet.

Hereinafter, a more preferred embodiment of the vertical water flow forming pulsator according to the present invention will be described in detail with reference to the accompanying drawings.

2, 3a, 3b is a partial cross-sectional view, a plan view, and a front view showing a pulsator of the washing machine according to the present invention.

As shown in the drawing, the vertical water flow forming pulsator according to the present invention forms the upper plate 45 and the lower plate 46 and the washing water in the lower portion of the reservoir 31 between the upper plate 45 and the lower plate 46. A plurality of water flow inlets 42 are formed to be introduced.

The vertical water flow forming passage 44 has a curved shape between the water flow outlet 41 and the water flow inlet 42 so that the washing water can be discharged to the water flow outlet 41 through the water flow inlet 42. The vertical shape of the vertical water flow passage 44 is such that washing water in the lower portion of the water reservoir 31 is rotated in the vertical water flow formation pulsator 40 by the rotation of the vertical water flow pulsator 40 during washing or rinsing. It can be drawn into the vertical water flow passage 44 and discharged to the water flow outlet 41.

On the upper surface of the upper plate 45 of the vertical water flow forming pulsator 40, a water flow outlet 41 protrudes into a cylindrical shape in a center portion, and an inner circular passage of the water flow outlet 41 is a shaft insertion tube 47. A shaft (not shown) of the reduction gear assembly 34 is inserted to fix the vertical water flow forming pulsator 40.

The lower part of the shaft insertion tube 47 adjacent to the lower plate 46 has a polygonal shape when the catching groove 48 is viewed from above as shown in FIG. 3A so that the shaft and the vertical water flow pulsator 40 do not fall down when the shaft rotates. Formed.

On the upper side of the upper plate 45, a plurality of water flow wings 43 for forming a water flow to the outside of the water flow outlet 41 is formed. The upper plate 45 may be formed slightly wider than the lower plate. This is to ensure that the washing water is filled in the lower portion of the reservoir 31 so that the washing water flows into the vertical water flow passage 44 from the water inlet 42.

Vertical flow-forming pulsator 40 of the present invention having such a configuration is coupled to the end of the shaft of the reduction gear assembly 34 with a screw or the like to prevent separation and the upper portion of the screw is capped (36) In addition, the gearbox assembly 34 is coupled to the outer lower portion of the reservoir 31 in a pair with the drive motor 33 in the outer box 30 of the washing machine.

The washing tank 32 coupled to the tub flange 35 inside the water storage tank 31 is located between the vertical water flow forming pulsator 40 and the water storage tank 31, and the vertical water flow lower than the washing tank 32. The part accommodating the forming pulsator 40 is slightly higher than the general washing tank by deforming the shape of the pulsator 40.

In the washing stroke or the rinsing stroke, a vertical water flow is formed in which the reduction gear assembly 34 which receives the driving force of the driving motor 33 by the belt rotates and is engaged with the shaft (not shown) of the reduction gear assembly 34. The pulsator 40 rotates.

The washing water flows in through the water inlet 42 formed between the upper plate 45 and the lower plate 46 by the rotation of the pulsator 40 and the upper plate 45 through the vertical water flow passage 44. At the center of the chopper is discharged to form a vertical water flow into the water flow outlet 41 is a cylindrical protrusion of a doughnut shape.

According to the present invention as described above, the vertical water flow forming pulsator 40 forms a vertical water flow different from the general water flow so that the laundry can be tangled well without washing or tangled during the rinsing stroke to obtain a better washing effect In addition, the vertical water flow can be formed only by the pulsator without other additional devices, thereby reducing the production cost such as cost reduction.
