The present invention is a shower water supply device of the washing machine, more specifically, the shower of the washing machine to improve the rinsing performance and cleanliness by removing the dirt remaining on the surface of the laundry by temporarily supplying water to the laundry in the dehydration process for rinsing It relates to a water supply device.

In general, the fully automatic washing machine of the pulsator type generates a rotational flow by driving the pulsator 12 in a state in which the dewatering container 11 rotatably installed in the washing tank 10 performs washing and rinsing functions. When the rinsing is completed, the dehydrating tank 11 and the pulsator 12 are rotated at the same time to dehydrate the water (see FIG. 1).

The washing and rinsing operation is performed by the same action, except that the rinsing operation is repeated several times to cleanly remove the dirt particles and detergent particles separated from the laundry, and the intermittent dehydration operation is performed during rinsing.

In spite of these efforts, dirt or scum removed from the wash water during drainage operation is drained out of the washing tank without being properly discharged out of the dewatering container, so that a relatively large amount of dirt and foam sinks and remains on the surface of the laundry.

When dehydration is carried out in the above state, some of the small particles are removed together with the residual water by high-speed centrifugal action, but most of the large particles are left in the laundry and the washing effect is halved. there was.

On the other hand, Figure 2 (a) (b) shows the installation state of the conventional water supply device, the former water supply device 20 is a detergent container 13 and the upper cover 14 mounted on the upper portion of the washing tank (10). It is laid in between, the latter is to supply water through the detergent container 13 under the same conditions as above.

However, since the water discharged through the water supply device 20 and the detergent container 13 is concentrated on a part of the laundry, the above-described conventional techniques have insufficient effect of removing dirt from the part where water is not sprayed during rinsing and dehydration. In other words, the dehydration function is lowered due to the concentrated supply of water.

The present invention has been made in view of the above problems of the conventional water supply device for shower dehydration, the purpose of the shower water supply device of the washing machine that can remove foreign substances such as dirt and detergent on the surface of the laundry when dewatering cleanly To provide.

The present invention also provides a shower water supply device of the washing machine to spray the water evenly over all parts of the laundry to prevent deterioration of the dehydration function due to the concentrated supply of water.

The present invention for achieving this object is configured to be immersed by the return spring in accordance with the presence or absence of water supply protruding by the water pressure and installed in the upper part of the washing machine to spray water on the whole part of the laundry surface In addition, the nozzle is sprayed with water during the spraying operation was positioned above the center of the laundry.

Therefore, the dirt or fines removed on the surface of the laundry and the inner surface of the dewatering tub are removed during hem dehydration to wash in a clean state, and the use of the washing machine is facilitated by the appearance of the water supply device.

Hereinafter, with reference to the accompanying drawings, a water supply device for shower dehydration of the washing machine of the present invention will be described in detail.

3 is a cross-sectional view of a state in which the water supply device of the embodiment is installed in the washing machine, and the dehydration container 11 is limited to dehydration during the whole process of the washing machine on the inner rear surface of the upper cover 110 coupled to the washing machine body 100. A water supply means 200 for intermittently supplying water is installed.

The water supply means 200 includes a first nozzle pipe 210 having a nozzle 212 at its distal end to be protruded in the longitudinal direction, a second nozzle pipe 220 into which the first nozzle pipe is slidably inserted, The second nozzle pipe is slidably coupled and is supported by the upper cover 110 is composed of a third nozzle pipe 230 is connected to the water supply pipe 250 of the tap water.

4 is a cross-sectional view of the water supply device, wherein the rear end faces of the first and second nozzle pipes 210 and 220 are respectively provided with support pieces 211 and 221 to which the release prevention and water pressure are applied during the sliding operation thereof. Springs 240 and 241 having elastic force are interposed between the support pieces and the blocking pieces 222 and 231 formed at the distal ends of the second and third nozzle pipes 220 and 230, respectively. .

The moment when the pressure of the water flowing into the third nozzle pipe 230 is applied to the second nozzle pipe 220 and the support piece 221 at the rear end thereof, the first nozzle pipe 210 and the support piece 211 at the rear end thereof. ), The first nozzle nozzles 210 and 220 protrude at the same time.

1. Each of the return springs 240 and 241 interposed on the opposite side of the support pieces 211 and 221 on which water pressure acts when the second nozzle pipes 210 and 220 protrude, is contracted. At this time, it is preferable that the elastic constants of the springs 240 and 241 are weak compared to the water pressure as a precondition for the water supply means 200 to operate smoothly.

When the water supply is stopped and the water pressure applied to the pipe of each nozzle tube is lost, the springs 240 and 241 contracted by the water pressure are restored to restore the first and second nozzle pipes 210 and 220. It is immersed coaxially in the inner peripheral surface of the 3 nozzle pipe 230.

On the other hand, the water supply means 200 is operated by the water pressure when the intermittent dehydration operation between the washing and rinsing and the continuous rinsing process is to disperse the water in a shower method, it is possible to apply to the whole process of washing These methods are all within the claims of the present invention.

In addition, Figure 5 shows the flow structure of the water supply device of the present invention, one end of the third nozzle pipe 230 is supported by the hinge 272, the other end is provided with a tension spring (273) and the motor ( The eccentric cam 270 driven by 271 is circumscribed so that the water supply means 200 swings up and down with the hinge 272 at its peak.

By changing the position of the nozzle 212 formed at the front end of the water supply means 200 by the above action it is possible to widen the dispersion angle and dispersion range of water.

Therefore, the water supply means 200 of the present invention as described above is operated at the time of interstitial dehydration between the laundry administration and the rinsing administration of the laundry to supply water for a short time, in the other inner operation of the upper cover 110 Immersion does not affect the take-out of laundry or rotation of the dehydration container 11 at all. When water flows in through the water supply pipe 250 of the third nozzle pipe 230 constituting the water supply means 200, the first nozzle nozzles 210 and 220 embedded therein protrude and the nozzle (at the tip) 212 is sprayed water toward the laundry located in the lower portion in the form of a shower in a state located approximately in the upper center portion of the dehydration container (11).

Therefore, when rinsing, the laundry and various debris or washing products remaining inside the dewatering container around it are removed by the water sprayed from the nozzle and the rotation of the dewatering container, so that clean washing is possible.

The present invention has the effect of improving the washing efficiency by spraying the water evenly in the laundry during intermittent dehydration operation, it is possible to prevent the obstacle due to the concentration of water and the use of the washing machine.
