BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spout (hereinafter referred to as a spout) attached to an undersink type or a stationary type water purifier for obtaining two types of purified water for use in a home lavatory or a kitchen. ) Used for a switching cock attached to the tip, connected to a double hose having two independent passages of flexible material such as rubber,
The present invention relates to a switching valve for selecting chlorine-free water purification or advanced water purification at a water discharge end.

[0002]

2. Description of the Related Art Conventionally, a stationary water purifier, which is relatively inexpensive and does not require installation work, has a switching cock for raw water and purified water attached to the tip of a faucet spout, and a switching cock for switching between raw water and purified water. I have. Undersink type water purifiers are combined with a dedicated faucet to obtain purified water.

[0003]

However, none of the water purifiers, including the water purifiers for hair-washing and cosmetics which have not been used so far, have a small amount of spouting water, so that they can be used for washing in the kitchen and washing hair on the dressing table. Therefore, there is a demand for high-purity water removal from which chlorine and mold odors are removed, even if the water is not highly adsorbed water.

Accordingly, the present invention provides two types of purified water from a single water purifier, namely, high-purity water from which only chlorine has been removed and highly purified water from which volatile organic compounds have been removed. We proposed a 2-way water purifier that could be applied separately,
An object of the present invention is to provide a switching valve that can obtain two types of convenience of purified water.

[0005] Another object of the present invention is as follows.
The present invention is to provide a switching valve that is convenient as a hair-washing shower or a kitchen shower with a hose by being connected to a hose made of a flexible material such as rubber or resin that forms the two passages.

[0006]

That is, two circular valve bodies having a sliding surface made of ceramic or resin connected to a hose having two passages made of a flexible material such as rubber or resin. Select high-purity chlorine-free water or high-purity small-purity water from a water purifier that supplies two types of purified water to the fixed side, introduce it to the side on the fixed side, pass through the sliding side via the bypass on the movable side, and again. The gist of the present invention is that the spout is returned to the fixed side and is discharged to the outside, so that high spouting water can be easily selected at the discharge tip for hair washing and washing, and highly treated purified water for drinking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view of the present embodiment. A main body 1 is formed by molding and firing alumina ceramics into a disk shape, and a sliding surface 2 has a surface roughness capable of maintaining watertightness.
Two circular plates polished to a parallelism of 0.8 μm are stacked together and assembled as a fixed-side valve body 3 and a movable-side valve body 4. The fixed-side valve body 3 has an L-shaped opening 5 on the side surface of highly purified water. The sliding surface 2 is further provided with an outflow port 6. Movable valve body 4
Is formed with a recess 8 that communicates with the outlet 6 from the opening 5 and discharges highly purified water to the rectification port 7 provided outside the main body 1. On the upper surface of the movable side valve body 4, a groove 11 for bonding a pin 10 fixed to a rotation shaft 9 is formed.
Is incorporated in the knob 12 by an appropriate method. The O-ring 13 has a role of pressing the movable side valve body 4 against the fixed side valve body 3 and generating a surface pressure so that they do not separate when a water pressure is applied.

The hose fitting 14 is for connecting a silicone hose 15 for introducing highly purified water to the fixed side while ensuring watertightness, and a butyl hose 16 for introducing chlorine-free purified water.
Is screwed into the main body 1 via a metal fitting 17 by a cap 18 and fixed.

Since the silicone hose 15 and the butyl hose 16 are flexible, the fixture 1 on the faucet side (not shown) is used.
9 can be pulled out.

FIG. 2 is a cross-sectional view of the present embodiment, and explains from introduction to inflow of chlorine-free purified water. The chlorine-free purified water that has passed through the fitting 17 is
1 through a large opening 21 opened in an L-shape from the side surface of the fixed valve body 3 to the sliding surface, through the opening 22 from the concave portion 8 of the movable valve body 4 in FIG. The water is sprinkled from the shower plate 23 at the bottom of 1.

FIG. 3 shows a plan view from the lower surface of the movable side valve body 4 and its cross section. The recess 8 has a flat surface so as not to overflow when the chlorine-free purified water and the highly purified water are continuously discharged. The shape was as shown in the figure.

[0012] Conventional water purifiers are generally used only for the purpose of high-purity water purification for drinking a small amount of water, but they cause rough hands and pain in hair when washing the hair. Because there was no one that incorporated a large amount of water for cleaning, which removed only chlorine, into a single water purifier, it was difficult to expand the market in both the United States and Japan due to lack of functions, and Since the user often felt inconvenienced, the present applicant separately proposed a water purifier capable of providing two types of water purification. Conventionally, in the case of the undersink type, space problems hardly occur, and the complexity of piping does not cause a problem. It was difficult to establish from the standpoint of space, and there was no development. Therefore, the present applicant can use the conventional faucet as it is, and can obtain the convenience that can be easily and freely selected by inventing a dedicated shower head equipped with a dedicated hose and a switching valve. is there.

FIG. 4 shows a cross section of a switching cock attached to a stationary type as another embodiment, in which a spout tip is attached to a faucet attachment port 24.
Insert a hose (not shown) into the hose connector 25,
Connected to the raw water inlet of the water purifier, chlorine-free water from the two-way water purifier passes through the butyl hose 16 side, which has a large water flow area, and a small amount of highly purified water passes through the silicon hose 15 side. The discharge of chlorine-free purified water in the embodiment was assumed to be a shower, as in the case of the undersink type.

In the case of the switching valve in FIG. 4, the chlorine-free water side may be separately and independently connected to the chamber 20 of the main body 1, but three hoses are required.

The annual amount of hair used for washing and washing kitchen is
Since it requires dozens of times of drinking, the adsorption function cannot be expected, but since it is not drinking, it can be determined that there is no need to consider removal of trihalomethanes.

[0016]

As described above, according to the present invention, two types of purified water can be switched at the tip of the spout, and in the case of shower hair washing and kitchen washing, the high spout of chlorine-free purified water is used for drinking. Has the benefit of being able to freely switch and select highly treated purified water. In addition, in combination with an undersink type water purifier, there is an advantage that the structure of the faucet is not complicated. Furthermore, in the case of a switching valve in combination with a two-way stationary water purifier, the hose is housed in two stations,
It has the benefit of miniaturization.
