DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixing tap having a water purification function in which a mixing tap has a water purification function.

[0002]

2. Description of the Related Art In recent years, a one-lever type using a ceramic switching plate has become the mainstream of mixer taps.
In addition, a built-in sink water purifier in which a water purifier is installed inside a sink and a water faucet dedicated to the water purifier is used in addition to a general faucet is used.

[0003] Here, in the present invention, raw water refers to a case where the raw water has not been purified by a water purifier, and it does not matter whether the state is hot water or water.

Hereinafter, the structure of a conventional mixing tap using a ceramic switching plate will be described. FIG. 4 is a cross-sectional view showing a state of passing water through a conventional mixing tap, and FIG. 5 is a cross-sectional view showing a water stopping state of a conventional mixing tap.

In FIG. 4 and FIG. 5, the mixing tap 1 has an inlet 2 for water and an inlet 3 for hot water on the inflow side and an outlet 4 on the outflow side, respectively. Hot water or a mixture of hot water and water is discharged from the discharge pipe 5. The mixing, passing and stopping of hot and cold water is performed by moving the lever 6 left and right or up and down with respect to the rotating shaft 7 so that the movable ceramic plate 8 interlocked with the lever 6 moves and the fixed ceramic plate is moved. Nine channels are opened and closed.

As shown in FIG. 4, when the lever 6 is depressed and moved to the water passage side, a water passage is formed between the ceramic switching plate composed of the moving-side ceramic plate 8 and the fixed-side ceramic plate 9, and as shown by arrows. It is discharged from the discharge pipe 5 following the flow path. When the lever 6 is pushed up and moved to the water stoppage side as shown in FIG. 5, the moving-side ceramic plate 8 blocks the inflow port of the fixed-side ceramic plate 9 and blocks the water passage.

FIG. 6 is a plan view schematically showing a relationship between a moving ceramic plate 8 and a fixed ceramic plate 9 of a ceramic switching plate in a conventional mixing tap. In FIG.
When the lever 6 is rotated left and right with respect to the rotation shaft 7 (refer to FIG. 4), the moving-side ceramic plate 8 that follows the rotation follows. Along with this, each of the holes 10 on the moving ceramic plate 8 side indicated by dotted lines, the water inflow holes 11 and the hot water inflow holes 12 on the fixed ceramic plate 9 side, and the water and hot water outflow holes 13 are formed. The diameter of the water channel changes, and the temperature of the water discharged from the discharge pipe 5 can be adjusted.

Next, a case where a water purifier with a built-in sink is attached to such a mixing tap will be described.

FIG. 7 is a schematic diagram showing a state in which a water purifier with a built-in sink is attached to a conventional mixing tap. In FIG. 7, the inside of the water purifier 14 is packed with a porous hollow membrane for filtering activated carbon and general bacteria as a filter medium.
A raw water inflow pipe 18 branched by a water pipe 16 and a joint 17 of the mixing tap 1 is connected to an inlet 15 of the water purifier 14, and a purified water outflow pipe 2 connected to a water tap 20 for a water purifier is connected to an outlet 19.
1 is connected. When the lever 22 of the water purifier faucet 20 is tilted, the raw water flows into the water purifier 14 through the raw water inlet pipe 18 and the inlet 15. In the water purifier 14, the residual chlorine in the raw water is first adsorbed by the activated carbon, and then the components such as iron rust and general bacteria are removed by the hollow membrane. In this way, the raw water is purified by the water purifier 14, and is discharged from the water purifier faucet 20 through the outlet 19 and the purified water outflow pipe 21.

[0010]

However, in the above-described structure in which the water purifier with the built-in sink is attached to the conventional mixing tap, the hole for attaching the mixing tap 1 to the sink 23 of the sink is required in the manufacturing process of the sink. The hole of the water tap 20 for the water purifier is opened by a contractor at the site where the sink is installed. For this reason, in the process of opening the hole of the water tap 20 for the water purifier, the sink 23 may be damaged, or the position where the hole is opened may be shifted, which has been a problem in construction.
In addition, since both the mixer tap 1 and the water tap 20 are required, the operability itself is not very good, and in addition, the cost is increased, so that there is a problem that the water purifier with a built-in sink is not popular. I was

[0011] The present invention solves the above-mentioned problems, and provides a mixing faucet function and a water faucet function for a water purifier.
It is an object of the present invention to provide a mixer tap with a water purification function which improves operability and eliminates a work process for opening a hole in a sink at an enforcement site.

[0012]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has an inlet and outlet for water, hot water and purified water on the inlet side and a common outlet on the outlet side, and opens and closes the solenoid valve. Mixer body equipped with a switch for controlling the mixer, and a peripheral device arranged in the order of a check valve, a water purifier, and a solenoid valve on the downstream side of the mixer tap body, and the lever of the mixer tap body is used exclusively for use. When is on the water flow side, the solenoid valve is closed and the flow rate of hot water and water is controlled by the mixing plug function, and when it is on the water stop side, the flow rate of purified water is controlled by opening and closing the solenoid valve.

[0013]

According to this structure, since the mixing tap has only the mixing tap function and the water tap function for the water purifier only by the mixing tap main body, the operability is improved and a work step of making a hole in the sink at the execution site can be omitted.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a mixer tap main body in a water-stopped state of the mixer tap with a water purification function of the present invention, FIG. 2 is a schematic configuration diagram of the mixer tap with a water purification function of the present invention, and FIG. It is sectional drawing of the mixing tap main body in the water-flow state of the mixing tap with a water purification function.

First, the outline of the present invention will be described with reference to FIGS. In FIG. 1, since the lever 6 is pushed up, the mixing stopper function of the mixing stopper main body 24 is in a water stop state. In this water stop state, only the purified water flowing from the water purification inlet 25 directly connected to the outlet 4 can be used. It can be discharged from the discharge pipe 5. Adjustment of the flow rate of the purified water flowing in from the purified water inlet 25 is performed by controlling the opening and closing of a solenoid valve 28 (see FIG. 2) connected to a signal line 27 by operating a switch 26. When the lever 6 is pressed down, the mixing tap function of the mixing tap main body 24 is in a water-passing state. In this water-passing state, the solenoid valve 28 is closed, and mixing is performed so that purified water does not flow in through the water inlet 25 for water purification. Use the stopper function.

As described above, since the mixing tap body 24 has both the mixing tap function and the water tap function for the water purifier, the operability is improved, and one of the sinks 23 (see FIG. 2) is previously provided in the same manner as before. All you have to do is make a hole.

The details of the mixing tap with a water purification function of the present invention will be described below with reference to FIG. 3 in addition to FIGS.

In FIG. 1 and FIG. 2, the mixing tap function of the mixing tap main body 24 with the lever 6 pushed up is in a water-stop state,
The water inlet 2 and the hot water inlet 3 have their respective water passages closed at the ends by a moving ceramic plate 8.
For this reason, only purified water flowing from the purified water inlet 25 directly connected to the outlet 4 can be discharged from the discharge pipe 5. Adjustment of the flow rate of purified water flowing in from the purified water inlet 25 is performed by controlling the opening and closing of a solenoid valve 28 connected to a signal line 27 by operating a switch 26. The electromagnetic valve 28 is provided in the flow path of the raw water inflow pipe 18, and controls the flow rate of raw water flowing into the water purifier 14 by opening and closing the electromagnetic valve 28. The purified water flowing out of the water purifier 14 passes through the purified water outflow pipe 21 and the check valve 29, flows into the water purification inlet 25, and is discharged from the discharge pipe 5.

In FIG. 3, the mixing tap function of the mixing tap main body 24 in which the lever 6 is depressed is in a water-passing state. It is opened by a plate 8. In this water flowing state, the solenoid valve 28 is closed, and the water purification inlet 25 is closed.
The mixing tap function is used to prevent purified water from flowing into the system. Raw water flowing backward from the outlet 4 to the water purification inlet 25 and heading toward the water purifier 14 is prevented by the check valve 29 and is prevented from flowing.
It does not reach side 4. Here, it is not bad to use the electromagnetic valve 28 with the valve opened, but it is not necessary to mix purified water with raw water, so that the water purification faucet function and the mixing faucet function are exclusively used for purposes.

As described above, the mixing tap with a water purification function of the present invention comprises:
By disposing peripheral devices in the order of the check valve 29, the water purifier 14, and the solenoid valve 28 on the downstream side of the mixer tap main body 24, the mixer tap main body 24 has both the mixer tap function and the water tap function for the water purifier. For this reason, the operability is improved, and the hole for the conventional mixer tap 1 opened in the manufacturing process can be used in the sink 23, so that the hole-drilling work at the site of the work is not required, and the construction can be simplified.

In the above description, it is assumed that the mixing stopper function is operated by a one-lever type. However, the mixing tap function in the present invention does not necessarily need to be operated by a one-lever type, and can be applied to, for example, a type operated by two taps for water and hot water.

[0023]

The mixing tap with a water purification function of the present invention has an inlet for each of water, hot water and purified water on the inflow side and a common outlet on the outflow side, and has a switch for controlling the opening and closing of the solenoid valve. The mixer tap body and a peripheral device arranged in the order of a check valve, a water purifier, and a solenoid valve on the downstream side of the mixer tap body, and the lever of the mixer tap body is on the water flow side due to exclusive use in use. At times, the solenoid valve is closed and the flow rate of hot water and water is controlled by the mixing plug function, and when it is on the water stop side, the flow rate of purified water is controlled by opening and closing the solenoid valve.

[0024] With this configuration, since the mixing tap function and the water tap function for the water purifier are both provided by the mixing tap body alone, the operability is improved and the work process of making a hole in the sink at the work site can be omitted.

Furthermore, since the mixing tap function and the water purification function are exclusively used, even if the water purification function fails, the mixing tap function can be used as usual.
