Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention adjusts water to produce alkaline water and acidic water by electrolyzing water or hot water or mixed water thereof, and selectively discharges the electrolyzed water and ordinary hot water or water. More particularly, the present invention relates to a water conditioner with an electrolytic water conditioner that discharges alkaline water, acidic water, and tap water from a common intake pipe. .

[0002]

Alkaline water produced by electrolyzing water is suitable for drinking, and is also useful for body washing, especially for removing keratin of the body, since soap and the like dissolve well. Water is suitable as bath water, hair wash, face wash, or body wash water after washing with soap. For this reason, in recent years, there is an increasing demand for supplying alkaline water or acidic water treated by an electrolytic ion water conditioning apparatus to a bathroom or washbasin. In the electrolytic water conditioner, alkaline water and acidic water flow out from separate drain pipes, and there are cases where it is desired to use water or hot water that is not subjected to electrolytic treatment as it is, so the piping system becomes diverse.
In addition, if water of each property can be used by switching to a normal faucet and a shower, the number of faucets and showers increases, which not only complicates the piping but also is inconvenient in handling.

An object of the present invention is to selectively discharge alkaline water, acidic water and non-electrolytically treated tap water electrolytically produced by switching valves, and to supply water of each property with a faucet and a shower. An object of the present invention is to provide a water conditioner with an electrolytic water conditioner that can be switched to and used.

[0004]

The above object of the present invention is to introduce water or hot water or a mixed fluid thereof into an electrolytic cell through a water supply pipe, and to generate a pair of alkaline ionized water and acidic water produced in the electrolytic cell. Equipped with a water-flowing type electrolytic water conditioner that drains water separately from the drainage pipes, a water supply pipe of the electrolytic water conditioner and a pair of drainage pipes each provided with a three-way valve, and a pair of drainage pipes Further, one outlet pipe of each three-way valve is connected to a common intake pipe, and the flow passage switching outlet of the three-way valve of the water supply pipe and the intake pipe are connected by a bypass pipe, and the intake pipe is further connected. This can be achieved by a water conditioner having an electrolytic water conditioner characterized in that a three-way valve for switching the flow path between the faucet pipe line and the shower pipe line is provided in the line.

Preferably, a flow switch for detecting ON / OFF of the electrolytic current of the electrolytic cell is provided in the pipeline between the three-way valve of the water supply pipeline and the electrolytic cell to detect the flow of fluid in the pipeline.

More preferably, a branch pipe for connecting another water supply pipe to the water supply pipe is provided, and an opening / closing valve is provided in this branch pipe.

[0007]

When the fluid passage of the three-way valve of the water supply line is opened to the electrolytic cell side, water is supplied to the electrolytic cell, and alkaline water and acidic water are discharged from the respective drainage lines. In this state, while opening the intake side of the three-way valve of the alkaline water drainage pipeline and closing the drain side, opening the drain side of the three-way valve of the acidic water drainage pipeline and closing the intake pipeline side opens the alkaline water intake circuit, Alkaline water is discharged from the intake pipe, and acidic water is drained to the drain. On the other hand, when the pair of three-way valves in both drainage pipes are switched to each other, the acidic water intake circuit is opened, the acidic water is discharged from the intake pipe, and the alkaline water is drained to the drain.

When the three-way valve of the water supply line is opened to the electrolytic cell side and both three-way valves of both drainage lines are opened to the drain side, and the polarity of the electrolytic voltage to the electrodes of the electrolytic cell is switched, the reverse electrolysis cleaning circuit is created. All of the water that was opened and washed is discharged to the drain.

Furthermore, when the electrolyzer side of the three-way valve of the water supply line is closed and the bypass line side is opened, the city water intake circuit is opened,
Water, hot water, or a mixed fluid thereof, which is not subjected to electrolytic treatment, is discharged to the water intake conduit. Also, in this state, stop the flow of the mixed fluid of water and hot water, and open the on-off valve of the branch pipe connected from the water pipe to the water supply pipe, the tap water will flow to the intake pipe as it is and drinking tap water Will be possible. In this case, tap water is taken out from the common water intake conduit while maintaining the mixing ratio of hot water and hot water for bath or shower.

Various kinds of water having different properties, such as alkaline water, acidic water, non-electrolytically treated hot water or tap water flowing through these intake pipes are selectively discharged to the faucet and the shower by the three-way valve of the intake pipes. .

Since the flow switch installed between the three-way valve of the water supply line and the electrolytic cell operates by detecting the flow of raw water before electrolysis, it is not affected by calcium precipitation of alkaline water and is stable for a long period of time. And work.

Preferably, as shown in the figure, a branch pipe line 24 for directly connecting the pipe 23 from the water supply source 18 is provided in the water supply pipe line 3, and an opening / closing valve 25 such as a solenoid valve is provided in the branch pipe line 24. . This is because tap water can be directly taken from the faucet 13 and / or the shower 14 by using the apparatus of the present invention, or the tap water can be electrolyzed to generate alkaline ionized water for drinking. .

As a more preferable specific example, in the embodiment shown in the figure, the electrolysis unit 1'is detected by detecting the flow in the water supply line 3'between the three-way valve 10 of the water supply line and the electrolysis unit 1,1. A flow switch 26 for controlling ON / OFF of the voltage supply to the first electrode is provided. When this type of flow switch is installed on the drainage pipe side, it is necessary to open and close a pair of drainage pipes 4a and 4b at the same time, so a two-stage flow switch having two channels and valves is required. Although the operation of the flow switch is often hindered by the deposition of precipitated calcium, the problem can be rationally solved by providing the flow switch 26 in the water supply conduit 3 '.

In the illustrated embodiment, the water supply pipe line 3'and the drain portion 9 are connected by a pipe line 27, and the pipe line 27 is provided with a valve member 28 for draining water and injecting a cleaning chemical liquid. This valve member 28
As shown in FIG. 2, the valve body 28b slidably inserted into the valve case 28a opens and closes the passage 28e between the fluid inlets and outlets 28c and 28d, and forms the chemical injection passage 28f at the axis of the valve body 28b. , The lid 28j is removed and the tip fitting of the chemical solution injecting hose is fitted, and when the chemical solution is introduced with the passage 28e closed while the cleaning circuit is opened as shown in the figure, chemical solution cleaning is performed.

With the above configuration, the three-way valve 1 of the water supply line 3
When the valve body 10c of No. 0 is pushed upward in the figure and the outlet 10 is closed, the outlet 10a is opened and water flows to the flow switch 26,
Electrolyzed water (alkaline water, acidic water) is generated. At this time, open the outlet 6a of the three-way valve 6 of the alkaline water drainage pipe 4a,
When the outlet 6b is closed and the outlet 5a of the three-way valve 5 of the acidic water drainage pipe 4b is closed and the outlet 5b is opened, the alkaline water intake circuit is opened, the alkaline water flows into the intake pipe 7, and the acidic water is drained. Is discharged. The alkaline water obtained by electrolytically treating hot water or tap water of appropriate temperature is used as drinking water, and is also suitable for body washing using soap. In addition, the pair of three-way valves 5 of both drainage pipes 4a, 4b
When the opening / closing of the outlets 5a, 5b and 6a, 6b is mutually reversed by operating 6, the acidic water intake circuit is opened, the acidic water flows into the intake pipe line 7, and the alkaline water flows into the drain. Acidic water taken in this case is useful as hair wash water, face wash water, or running water after soap body washing. On the other hand, when the outlet 10a of the three-way valve 10 of the water supply pipe is closed and the outlet 10b is opened, the city water intake circuit is opened, and tap water that is not subjected to electrolytic treatment or hot water of an appropriate temperature is directly supplied to the intake pipe. . Further, the outlets 5a, 6 of the three three-way valves 5, 6, 10
When the a and 10a sides are closed and the outlets 5b, 6b and 10b are opened, all the electrolyzed water is drained to the drain. This is used not only as a reverse cleaning water circuit for dissolving and cleaning calcium or the like by reversing the electrode characteristics of the electrolysis unit, but also as the chemical cleaning circuit.

The three-way valves 5, 6, 10 may of course be manually operated, but preferably a motor valve is used, and cams 30a, 30b, 30 which are rotationally driven by a motor 29 are used.
The valve rods of the valve bodies 5c, 6c, and 10c are engaged with c to open and close. In this case, the respective cams 30a, 30
Of course, the shapes and relative angles of b and 30c are adjusted so that the desired flow path switching operation is performed.
Similarly, a motor valve is also used as the three-way valve 12 of the water intake pipe 7, and the cam 16 for driving the motor 15 operates the valve body 12c. In this way, the three-way valve 5, 6, 10, 1
If two motor valves are used, they should be operated remotely by an electric control circuit. FIG. 3 is a block diagram of an electric circuit when operated by electric control. When the signal of the water type selection switch of the water discharged from the intake pipe is input to the control circuit, the control signal is input to the A motor valve control circuit via the output circuit, and the motor 29 performs a predetermined operation based on this.
