Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water supply device for a washing machine, and more specifically, to a water supply device that diffuses water in a shower-like manner and supplies it into a washing tub.

Since the phosphorus pollution caused by synthetic detergents and their safety to the human body have been raised as a problem, so-called "powdered soaps" based on natural oils and fats such as beef tallow and coconut oil are being reconsidered as an alternative. However, when washing clothes using powdered soap, various problems have been pointed out in terms of usability, finish, etc. In other words, undissolved soap granules remain due to poor solubility, and soap components chemically combine with metals such as calcium contained in tap water, resulting in insoluble metal soap that has no cleaning effect. Soap scum forms. Many of these soap particles and soap scum float on the water surface, but they adhere to the surface of washed laundry when it is taken out of the rinse water or when it is drained. Moreover, the soap particles and soap scum mentioned above tend to adhere to the inside of the tank, and it is quite troublesome to wash them off. By the way, according to Utility Model Publication No. 49-42867, a water supply device for a washing machine is proposed which includes a diffusion plate for diffusing water. To roughly explain this device, there is a water supply port that communicates with a water supply source, a diffusion plate that is disposed below the water supply port and diffuses and supplies water to the washing tub, and a diffusion plate that is intermittently tilted. The diffusion plate is equipped with an articulation device that fixes its position, and the inclination angle of the diffuser plate is intermittently adjusted by the articulation device, thereby changing the amount of diffused water in multiple stages. However, in this conventional device, since the inclination angle of the diffuser plate can only be changed intermittently, the state of water diffusion cannot be changed continuously, and in particular, the above-mentioned soap particles can be pushed toward the overflow port. It is unsuitable for flushing,
Moreover, the switching operation required a lot of getting used to and was inconvenient.

Therefore, an object of the present invention is to continuously change the diffusion state of water with a simple operation so that soap particles, etc. floating on the water surface can be swept away toward the overflow port and removed. Another object of the present invention is to provide a water supply device that can cleanly wash away laundry and soap particles adhering to the inside of the tub.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

First, a water supply device according to the present invention will be schematically explained with reference to FIGS. 1 and 2. This water supply device 1 is attached to the upper part of the inner wall facing the overflow port 3 in the washing tub 2, and is connected to a water supply faucet (not shown) as a water supply source via a hose 4, as shown by the imaginary line in FIG. 1A. Ru. According to this water supply device 1, the tap water supplied through the hose 4 is divided into three directions at the same time as shown by the chain lines in the figure, and is supplied at the same time. can be changed continuously. Incidentally, Fig. 1 a and b show the normal water supply state, and Fig. 2 a and b show the state in which the push button 5 is pushed in so that the water is thoroughly diffused into the washing tub 2. has been done.

As shown in detail in FIG. 3, this water supply device 1 includes a housing 6 that is watertightly formed from a case body 7 with an open bottom and a bottom plate 8 assembled to the bottom of the case body 7. . The case body 7 has a connecting tube 9 inserted into the hose 4 on its side wall, and a guide extending downward toward the bottom plate 8 is provided approximately at the center of the upper wall of the case body 7. Cylinder 1

is provided, and two water outlets 16, 16 are provided behind it with the aperture 12 in between. In this case, a cylindrical enclosure dam 17 that is shorter than the case body 7 is provided around the front water outlet 15. Further, the rear water outlets 16, 16 are provided with a valve body 20 that adjusts the degree of opening of the water outlets in relation to the operation of the push button 5. This valve body 20 is
It is configured to be held within a slot 22 formed at the lower end of the stem 10, and is formed to have a slightly smaller diameter than the diameters of the respective water outlets 16, 16 so as to fit loosely into them. two valve heads 2
1. A tapered surface 23 whose diameter gradually decreases downward is connected to the valve head 21. In addition, as shown in FIG.
6, 16 is installed in the slot 22 so as to be loosely fitted from below.

In addition, this water supply device 1 includes each of the above-mentioned water outlets 1
A water sprinkling plate 24 is provided for diffusing water flowing out from the washing tub 2 into the washing tub 2. This water sprinkling plate 24 has a first water sprinkling plate 25 disposed corresponding to the front water outlet 15 and a second water sprinkling plate 26 disposed corresponding to the rear water outlets 16, 16. , the front edge of the first water sprinkling plate 25 is curved in an arcuate shape to spread the water over a wider area, as shown by the chain line in FIG. The edge is also curved to follow the inner wall of the opposing washing tub 2, but there is a rib 2 on that part.
7 is provided. In this example, the first
The water sprinkling plate 25 and the second water sprinkling plate 26 are integrally molded in a stepped manner via a connecting support 28 so that the first water sprinkling plate 25 is located above, and the lower surface of the bottom plate 8 is attached to the upper end of the sprinkling plate 25. An engaging protrusion 31 is formed which cooperates with an engaging groove 30 of the retainer 29 provided in the retainer 29 . Therefore, by engaging this protrusion 31 with the groove 30, the water spray plate 24 is connected to the holder 2.
9 and 29 directly below each water outlet 15 and 16. In addition, this water sprinkler plate 24
In relation to this, a rear water outlet 1 is provided on the lower surface of the bottom plate 8.
6, 16 and the first water sprinkling plate 25 are provided, and in this case, the outer end of each curtain plate 32, 32 is connected to each water outlet 16, 16.
It is bent into an L shape to encircle the . The housing 6 has mounting through holes 33 and 34 provided in the case body 7 and the bottom plate 8, and the screws 3 inserted into the through holes 33 and 34.
5, it is attached to the corner of the washing tub 2 facing the overflow port 3 as described above, but in that case,
Actually, as shown in FIG. 5, the mounting cover 36 is fastened together with screws 35.

Next, the operation of this invention will be explained. Fifth
The figure shows a normal water supply state when washing water or rinsing water is stored in the washing tub 2. In this case, the valve head 21 is lifted upward by the coil spring 13 together with the push button 5, so that the rear water outlet 16 is held in a fully open state. Therefore, the water supplied into the housing 6 from the hose 4 via the connecting pipe 9 flows out from the front water outlet 15 and the two rear water outlets 16, and is distributed to the corresponding first and second water sprinkling ports, respectively. The first
Water is supplied into the washing tub 2 while spreading in three directions as shown by the chain lines in Figures a and b. That is, the water flowing out from the front water outlet 15 collides with the first water sprinkling plate 25 and becomes the first diffused water that spreads the most in front of the first water spray plate 25 and is supplied with water.
The water from 6 collides with the second water sprinkling plate 26, and most of it is supplied as second diffused water in a state where it is spread smaller than the first diffused water. The remaining water that has collided with 26 climbs over the ribs 27 and scatters as third diffused water on the inner wall side of the washing tub 2, and is supplied into the tub along the inner wall. During this normal water supply, the rear water outlet 16 is fully open as described above, and the water pressure inside the housing 6 is kept low, so water is supplied softly and water splashes due to collision with laundry etc. rarely occurs. Also, front water outlet 1
Since a surrounding weir 17 is provided around the casing 5, for example, as in this embodiment, there is a water inlet (connecting tube 9) on the side of the casing 6, so that water such as eddy current inside the casing 6 is prevented. Even in cases where a directionality (so-called "water habit") occurs, the water habit is caused by the above-mentioned enclosing weir 1.
7 and flows toward the front water outlet 15, the water is rectified. Therefore, without being affected by the "water habit" of the tap water supplied from the hose 4, the first diffused water in particular can be supplied into the washing tub 2 so as to provide a substantially uniform shower. I can do it.

On the other hand, when the push button 5 is pushed against the coil spring 13 from the above state, the valve head 21 is also pushed down accordingly, and the rear water outlet 16 is greatly constricted by the valve head 21. As a result, the water pressure inside the housing 6 increases, and the force of the water flowing out from the front water outlet 15 becomes stronger, so that the first diffused water is sprayed to fill the tank as shown in Figure 2 a and b. Ru. On the other hand, the amount of outflow from the rear water outlet 16 is reduced due to the throttling effect of the valve head 21, but on the other hand, the force becomes stronger, so that the second and third diffused water also spreads more widely. In this way, the entire inside of the washing tub 2 is covered with the diffused water, but since the taper surface 23 whose diameter gradually decreases is provided below the valve head 21, When pushing the push button 5, the rear water outlet 16 is gradually narrowed, so that especially the first and second diffused water,
continuously changes from the state shown in Figure 1 to the state shown in Figure 2,
And it will change smoothly. Therefore, by pressing the push button 5 at the end of rinsing, etc., soap particles, soap scum, etc. floating on the water surface can be washed away from the front side of the device 1 toward the overflow port 3. . In this case, since the curtain plate 32 is provided between the first water sprinkling plate 25 and the rear water outlet 16, the first diffused water is interfered with by the water vigorously jetted from the rear water outlet 16. It can be seen that it spreads almost uniformly. In addition, since the two water sprinkling plates, the first water sprinkling plate 25 and the second water sprinkling plate 26, are arranged in a stepped manner, the two diffused water spreading forward as shown in the figure,
is obtained, thereby making the action of washing away soap particles etc. floating on the water surface more effective. On the other hand, a guide tube 11 for guiding the stem 10 of the push button 5 is formed to penetrate into the opening 12 of the bottom plate 8 from the case body 7 side, and the valve body 20 is held at the lower end of the stem 10. As a result, the watertightness of the case body 7 is sufficiently ensured, and in particular, there is a structural advantage that no sealing member such as an O-ring is required when the stem 10 of the push button 5 is penetrated into the housing 6. It also has

In the above embodiment, the case where soap particles etc. floating on the water surface are swept away toward the overflow port 3 was explained as an example, but when the laundry is taken out after draining, the push button 5 may be pressed. By pressing the button to shower the entire laundry with diffused water, you can wash away soap particles, etc. adhering to the surface, and also wash away dirt such as soap scum adhering to the inside of the tub. be able to.

Needless to explain in more detail, this water supply device 1 is also effective for eliminating foam from synthetic detergents;
The arrangement of each water outlet and the number thereof are not limited to those in the above embodiment, and can be arbitrarily changed in design depending on the size, shape, etc. of the washing tub to which it is applied.

As is clear from the description of the embodiments described above, according to the present invention, water can be easily supplied according to the water supply purpose by operating the push button provided on the hand side without adjusting the water faucet or the like. The water inside can be dispersed in a fan-like manner, making it particularly useful for flushing soap particles and soap scum from powdered soap toward the overflow port, or for washing them off the surface of laundry or inside the washing tub. .
