Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a water supply valve of a water heater for supplying cold water or hot water for drinking.

[Conventional technology]

As shown in FIGS. 3 and 4, such a chiller-heater has a tank (2) arranged in an upper part of an outer box (1), and a heater (7) and a cooler ( 8) is installed, a compressor (3) that constitutes a part of the refrigeration cycle is installed in the lower part of the outer box (1), and a water supply valve communicating with the tank (2) is provided on the front surface of the outer box (1). (5) is provided, and a water supply cylinder (6) is projected downward from the main body (5a) of the valve (5). In the figure, (4) indicates a water supply lever for opening and closing the water supply valve (5).

By the way, the water bottle (6) is formed with a short length as shown in Fig. 5 so that a large cup of water for drinking can be placed below the water bottle (6) and the whole device does not become large. There is.

[Problems to be solved by the device]

In this way, if the length of the water supply cylinder is short, the water is not rectified sufficiently, and the unrectified water is discharged from the tip of the water supply cylinder. If you get wet with it, or if you supply hot water, splashing hot water on your hands may cause burns, which is dangerous.

In order to solve such inconvenience, a method of attaching a current plate (11) to the inner wall surface of the water supply cylinder (6) can be considered as shown in, for example, FIG. 6 and FIG. Since the water bottle (6) itself to be attached is short, the current plate (11)
Becomes short and, as a result, the rectifying action is not sufficient and is not effective.

The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, to prevent water discharged from the water supply pipe from spattering even when the water supply pipe is formed to be short in a water cooler and water supply device, and to be held by hand when hot water is supplied. You can avoid the risk of burns, and less water left,
An object is to provide a water supply valve for a hot and cold water machine that can be manufactured easily and at low cost.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a double structure of an outer cylinder and an inner cylinder for a water supply cylinder projecting downward from the water supply valve main body, and a small number, for example, two, for supporting the inner cylinder in the outer cylinder. The gist is that the support member is integrally formed at the opposing position between the inner cylinder and the outer cylinder.

[Action]

According to the present invention, the water flowing into the water supply cylinder is divided into the outer cylinder and the inner cylinder, and the pressure decrease due to this and the surface tension of the water flowing into the inner cylinder causes the water on the outer cylinder side to move inward. Pulled to the cylinder side,
Water discharged from the outer cylinder does not splash around.

Further, since the inner cylinder, the outer cylinder and the supporting member are integrally molded, the manufacturing is easy and inexpensive, and the supporting member is few, so that the residual water can be reduced.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a vertical side view showing an embodiment of a water supply valve for a water heater of the present invention, and FIG. 2 is a cross-sectional plan view of a water supply cylinder, which is the main part of the water supply valve of the present invention. Similarly, the outer cylinder (1) communicates with the tank (2) arranged in the outer box (1).
The water supply cylinder (6) is provided on the front surface of the main body (5a) so as to project downward from the lower part of the body (5a), and the water supply valve (5) is provided with the water supply lever (4).

As the structure of the water supply cylinder (6), the outer cylinder (9) is used in the present invention.
The outer cylinder (9) has a double cylinder structure composed of the inner cylinder (10) and the inner cylinder (10).
An inner cylinder (10) having the same length as the outer cylinder (9) and a diameter of about ½ of the diameter of the outer cylinder (9) was concentrically arranged in the outer cylinder (9).

In the figure (9a), the inner cylinder (10) is supported inside the outer cylinder (9).
The support members provided at opposite positions of the book are shown.
0) The outer cylinder (9) and the support member (9a) were integrally formed. This support member (9a) may be three or the like.

Next, the usage and action will be described.

The water in the tank (2) is heated by the heater (7) or cooled by the cooler (8) to become hot water or cold water.

To drink hot or cold water, place a cup or a teacup under the water bottle (6) and push the water supply lever (4) to open the water supply valve (5) to open the tank (2) to the body of the water supply valve (5). Hot water or cold water is discharged downward from the lower end of the water supply pipe (6) through (5a) and the water supply pipe (6) and poured into a cup or the like.

At this time, when hot water or cold water flows from the main body (5a) of the water supply valve (5) into the water supply cylinder (6), the outer cylinder (9) and the inner cylinder (10).
Is divided into two streams by and, and further the support member (9a)
Is divided by, which causes a pressure decrease in the flow,
Moreover, the hot water or water flowing out from the outer cylinder (9) side is pulled toward the inner cylinder (10) side by the surface tension.

As a result, hot water or water discharged from the outer cylinder (9) side does not scatter around.

Moreover, since the number of supporting members (9a) is only two, little residual water is generated.

[Effect of device]

As described above, the water supply valve of the chiller-heater of the present invention can prevent water and hot water discharged from the water supply pipe from splashing to the surroundings even if the water supply pipe has a short length, and can prevent the floor surface from getting wet. Can be prevented.

Further, in particular, it is possible to prevent burns from being caused to the hands by splashing hot water, and to improve safety.

Furthermore, even if the inner cylinder and the support member are provided, the amount of residual water does not increase, and since the inner cylinder and the support member are integrally molded with the outer cylinder, the manufacturing is easy and the cost is low.
