Description

[Detailed Description of the Invention] This 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.

The biggest problem when using so-called "powdered soap" which is mainly made of natural fats and oils such as beef tallow and coconut oil is the formation of soap particles called metallic soap, which are insoluble and have no cleaning effect. Therefore, the applicant has devised a method to continuously change the diffusion state of water supplied to the washing tub with a simple push button operation, thereby flushing out soap particles, etc. floating on the water surface towards the overflow port. Several applications have already been filed for water supply devices that can clean laundry and soap particles adhering to the inner walls of the tank (see, for example, Japanese Patent Application No. 1983-204891). ).
By the way, there are disparities in tap water pressure from region to region. Therefore, in places where the tap water pressure is abnormally high, the force of the shower water becomes too high, causing a problem in that droplets come out from the washing tub when water is supplied and wet the surrounding floors, etc.

This invention was made in view of the above-mentioned problems, and its purpose is to provide a water supply device that can be easily changed to a low-pressure type or a high-pressure type depending on the tap water pressure used.

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

First, the water supply device according to this 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 water overflow port 3 in the washing tub 2, and is connected to a water supply faucet (not shown) which is a water supply source through a hose 4 shown by an imaginary line in FIG. 1A. Concatenated. This water supply device 1
According to the above, tap water supplied through a hose 4 is divided into three directions at the same time as shown by the dashed lines in the figure, and by operating a push button 5, the state of dispersion can be changed continuously. It's becoming possible to change. 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 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. 4, the mounting cover 36 is screwed together with the screws 35.

Next, the operation of this invention will be explained. In a normal water supply state, that is, when washing water or rinsing water is stored in the washing tub 2, the valve head 21 is lifted upward by the coil spring 13 together with the push button 5, as shown by the imaginary line in FIG. As a result, the rear water outlet 16 is kept fully open. Therefore, the water supplied into the housing 6 from the hose 4 via the connecting tube 9 flows through the front water outlets 15 and 2.
The water flows out from the two rear water outlets 16, is diffused by the corresponding first and second water sprinkling plates 25 and 26, and spreads out in three directions as shown by the chain lines in FIG. Water is supplied within 2 hours. 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. Further, since a surrounding weir 17 is provided around the front water outlet 15, there is a water inlet (connecting tube 9) on the side of the casing 6, for example, as in this embodiment, and the inside of the casing 6 is Even if a directional flow (so-called "water habit") of water such as a vortex occurs in the flow, the water habit will be rectified when it overflows the enclosure weir 17 and heads toward the front water outlet 15. Therefore, without being affected by the "water habit" of the tap water supplied from the hose 4, especially the first diffused water 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. .

As described above, the state of water diffusion can be changed continuously by operating the push button 5. According to this invention, the case body 7
By changing the mounting direction of the push button 5 with respect to the guide tube 11, this water supply device can be set for use in high pressure areas and for low pressure areas. That is,
When used in areas with high tap water pressure, the fourth
As shown in the figure, the stem 10 of the push button 5 is inserted by aligning the slit 42 with the notch 40.
can be inserted into the guide tube 11. As a result, the water inside the housing 6 flows through the first and second water outlets 1.
5, 16 as well as slits 42 and notches 4
0, the internal pressure of the casing 6 will not increase more than necessary, and therefore,
No more splashes from inside the washing tub. On the other hand, in a low pressure area, the stem 10 may be inserted into the guide tube 11 in the opposite direction to that shown in FIG. 4, and the notch 40 may be closed with the leg piece 41 on the opposite side. The slit 42 may have a size such that it always communicates with the notch 42 regardless of the depressed position of the push button 5, or the slit 42 communicates with the notch 42 only when the push button 5 is depressed to the lowest position. They may be formed so as to communicate with each other.

In the above embodiment, the case where soap particles etc. floating on the water surface are swept away towards the overflow port 3 was explained as an example, but when taking out the laundry after draining the water, it is possible to press the push button 5 to do so. By showering the entire laundry with diffused water, you can wash away soap particles adhering to the surface, and also wash away soap scum and other debris adhering to the inside of the tub. can. Needless to explain in more detail, this water supply device 1 is also effective for eliminating foam from synthetic detergents.On the other hand, the arrangement of the water outlets and their number are not limited to the above embodiments, and may be applied. The design can be changed arbitrarily depending on the size and shape of the washing tub.

As is clear from the above description of the embodiment, according to this 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 etc. The water inside can be dispersed in a fan-like manner, which is particularly useful for flushing soap particles and soap scum from powdered soap toward the overflow port, and for washing them off from the surface of laundry or inside the washing tub. By simply changing the orientation of the push button stem inserted into the guide tube of the case body by 180 degrees, this water supply device can be easily changed to high-pressure or low-pressure use.
