The present invention relates to a water supply and drainage device of the dishwasher, and in particular, to filter the dirt contained in the wash water by the filter during water supply to re-clean water to be replenished, and to separate the dirt filtered by this filter when draining and discharged together with the wash water The present invention relates to a water supply and drainage device of a dishwasher, which allows the washing water to be replenished cleanly at all times.

As shown in FIGS. 1 and 2, a conventional dishwasher includes a spray arm 2 installed at an inner bottom of the dishwasher main body 1, and a water supply and drainage pipe installed at one side of the bottom of the dishwasher main body 1. As shown in FIG. A coarse filter 3 is coupled to the upper portion of the upper portion 11, and a water supply pipe 4 is connected to the water supply pipe 11 a connected to the water supply and drain pipe 11, and a water discharge pipe 11 b connected to the water supply and drain pipe 11. To the drain pump 5 is coupled.

The conventional dishwasher sprays water by the spray arm 2 to wash the dishes, and the dirt mixed in the washing water is first filtered by the coarse filter 3, and the washing water passing through the coarse filter 3 is fine. The filter 6 is supplied to the spray arm 2 by the feed water pump 4 and re-injected. In the drainage, the contaminated washing water is discharged to the outside by the drainage pump 5.

As described above, the conventional dishwasher prevents dirt from being caught in the fine filter 6, thereby obstructing the flow of washing water in the water supply direction. After passing through (6), it was mixed with the washing water again, and there was a defect that the dirt in the water supply part did not properly filter the dirt.

The present invention has been made to solve the above-mentioned conventional defects.

The present invention is a cleaning means such as a spray arm for spraying and washing the water contained in the interior of the dishwasher main body, and the water supply means for re-watering the washing water collected in the water supply pipe installed in the bottom of the dishwasher body to the washing means And, when water is supplied to the water supply line of the dishwasher equipped with a drainage means for draining the wash water after washing, the clean water is filtered again by filtering the dirt contained in the wash water. Provided is a water supply and drainage device for a dishwasher provided with means.

Hereinafter, an embodiment will be described in more detail with reference to the accompanying drawings of the present invention.

3 is a cross-sectional view showing the configuration and operation of the water supply and drainage device of the dishwasher according to the present invention, and FIG. 4 is a perspective view of the main part, with reference to FIGS. 3 and 4 below. A coarse filter 3 is coupled to an upper portion of the water supply and drainage pipe 11 installed at one side of the bottom of the water supply pipe 11a, and a water supply pipe 11a is connected to one side of the water supply pipe 11a. As an example, the water supply side first rotating plate 7 provided with the fine filter 6 detachably is provided.

In addition, a drain side second rotating plate 8 is rotatably coupled to the shaft 8 'at an end portion of the drain pipe 11b connected to the lower portion of the water supply and drain pipe body 11.

Both ends of the connecting rod 9 are eventually connected to the water supply side first rotation plate 7 and the drainage side second rotation plate 8 by hinges 9a and 9b, so as to be connected to the water supply side first rotation plate 7. The drainage side second rotating plate 8 is coupled to each other, and the spring 10 having the drainage side second rotating plate 8 elastically supported to the side blocking the water supply pipe 11a at an upper end of the water supply side first rotating plate 7. ) Is connected.

The fine filter 6 is detachably coupled to the water supply side first rotating plate 7.

The fine filter 6 may be detachably coupled to the insertion groove 7a formed in the water supply side first rotating plate 7, that is, replaceably.

The drain side second rotating plate 8 is shown to be partially attached to the net 8a, but may not be attached to the net 8a.

Referring to the effects of the present invention as described above are as follows.

3 is a cross-sectional view showing the water supply state, b is a cross-sectional view showing the drainage state. First, when supplying water, as shown in FIG. 3A, the water supply-side first rotating plate 7 pumps the pumping force of the water supply pump 4. By blocking the front of the water supply pipe (11a) by the dirt contained in the wash water is filtered. In other words, the washing water flows in the direction of the arrow shown in FIG. 3A, and the dirt is filtered by the fine filter 6 and then supplied to the spray arm 2.

At the time of drainage, as shown in FIG. 3B, the drain side second rotary plate 8 is opened into the drain pipe 11b by the drain pressure and connected to the water supply side first rotary plate 7 by the connecting rod 9. ) Is opened in front of the water supply pipe (11a) so that the washing water flows out in the opposite direction to which the dirt is filtered, that is, the direction of the arrow of b, the fine filter (6) is kept clean.

At the end of the drainage, the water supply shaft first rotating plate 7 and the draining side second rotating plate 8 are returned from the b state to the a state, that is, to the original state by the restoring elasticity of the spring 10.

As described above, the present invention has the advantage of keeping the fine filter 6 clean because the water passes in the opposite directions with respect to the fine filter 6 during feeding and draining, and the fine filter 6 is kept clean. As a result, when the washing water is supplied, the fine filter 6 maintains its function, thereby improving the dish washing effect.
