Further, as shown in FIGS. 3 and 4, the operation lever 11 is connected to a switching valve 9 described later and is configured to be rotatable horizontally and vertically. By operating the switching valve 9 by operation, in addition to adjusting the flow rate and stopping water, it is possible to arbitrarily operate each usage mode (mode) of purified water usage and raw water usage from cold water to hot water. .

That is, as shown in FIGS. 3 and 4, in the switching plug A, in addition to the discharge flow passage 14 communicating with the discharge port 13 opened at the tip of the discharge pipe 12, the hot water supply pipe 22 is communicated. A hot water supply passage 22a and a water supply passage 23a communicating with the water supply pipe 23, a purified water outgoing passage 24a for sending water to the water purifier B, and a purified water multiple passage 24b for guiding purified water from the water purifier B to the discharge passage 14 at both ends thereof. A plurality of flow paths such as the purified water flow path 24 to be formed are formed.

As shown in FIGS. 7 and 8, the switching valve 9 is connected to the first valve body 9a fixedly arranged in the plug body 10 and the operation lever 11 so as to move horizontally and vertically. It has a rotating second valve body 9b, and the first valve body 9a has a hot water inflow hole 16 communicating with the hot water supply passage 22a, a cold water inflow hole 17 communicating with the water supply passage 23a, and a water purifier B. In addition to the purified water hole 18 communicating with the purified water outgoing path 24a for sending to the discharge water passage 24a, a discharge hole 19 communicating with the discharge flow passage 14 is formed, and the second valve body 9b has an inflow guide hole 20 and an outflow guide hole 21. And form.

The correspondence of the communication between the discharge hole 19 of the first valve body 9a and the other holes 16, 17, 18 is determined by rotating the operation lever 11 in the horizontal and vertical directions so that the second valve body 9b is rotated. By switching the operating position, it is possible to take out cold water, hot water, hot / cold mixed water of any temperature in which cold water and hot water are mixed, and further purified water via the water purifier B.

In the present embodiment, the water discharge amount can be adjusted by the vertical position of the operation lever 11. When the lever 11 is in the upper position, the water is stopped, and in the lower position, the water is discharged. In addition, depending on the horizontal switching position, it is possible to switch between cold water, hot / cold mixed water, hot water, and purified water modes.

As described above, the switching plug A is configured so that all operations can be performed by operating the operation lever 11 alone.

In the switching plug A configured as described above, the water treatment device connection fitting 1 including the connection ports 2 and 3 which is the gist of the present invention is provided under the plug body 10 of the switching plug A from the plug body 10. It is exposed.

In the present embodiment, the water treatment device connecting fitting 1 is provided in the water treatment device connecting case a as shown in FIG. Is provided downwards.

Here, the water treatment device connection fitting 1 for connecting the water purifier B will be described. As shown in FIGS. 3 and 4, the water treatment device connection fitting 1 includes a forward connection port 2 and a return connection port 2. The connection port 3 and the connection ports 2 and 3 are formed so as to be exposed from the plug body 10 to the outside so that the water purifier B can be easily connected.

Further, when the water purifier B is detached, since the connection ports 2 and 3 are arranged downward, even if the lever is accidentally switched to the water purification side, the connection ports 2 and 3 are The water falls down and can be received at the sink, so that the user is not wet and the floor of the kitchen is not soaked.

Further, the connection ports 2 and 3 are fitted into the inner space of the water treatment equipment connection case a, for example, as shown in FIGS. If the plugging attachment 26 having the plugs 26a and 26b for closing 3 is closed, the switching plug A can be used as a hot and cold water mixing faucet without installing a water treatment device such as the water purifier B.

Also, when adding some kind of water treatment device other than the water purifier B or the like as in the present embodiment, the connection fitting 1 may be used, and in that case, the compact as in the present embodiment. Can be installed neatly.

Next, the water purifier B will be briefly described. As shown in FIGS. 3 and 4, the water purifier B is connected to the connection pipes b connected to the connection ports 2 and 3 and is continuously connected to the connection pipe b. It is composed of a water purification unit d.

The connecting tube b is composed of an outward connecting tube b1 and a returning connecting tube b2, and a raw water inflow path 31 and a purified water outflow path 32 are formed in the outward connecting tube b1 and the backward connecting tube b2, respectively. . The raw water inflow passage 31 is connected to the outward connection port 2 of the switching plug A, the purified water outflow passage 32 is connected to the return passage connection 3, and the outward connection port 2 is connected to the purified water outward passage 24a. The return port 3 is connected to the purified water return route 24b.

As shown in FIGS. 3 and 4, the water purification unit d is composed of a first water purification unit 33 and a second water purification unit 34. The first water purification unit 33 stores activated carbon 35, and The second water purification section 34 accommodates the hollow fiber membrane 36 inside the cartridge 37.

The first water purification unit 33 and the second water purification unit 34 are housed in the water purification unit case 38, and the water purification unit case 38 is connected to the connecting tube b.

A lid 38a is attached to the water supply pipe side of the water purifier case 38. By removing the lid 38a, the water purifier d in the case 38 can be attached and detached, and the water purifier B of the water purifier B can be attached. It is easy to maintain.

By the way, 25 shown in FIG. 4 is a check valve provided in the purified water outlet 32 near the communicating portion between the purified water outlet 32 and the outward connection port 3. Water is prevented from flowing from the discharge passage 14 to the water purifier B side.

Further, 27 is a safety valve made of a shape memory alloy, and when the safety valve 27 reaches a constant temperature, it opens to the hot water drain hole 28 side provided on the lower surface of the water purification unit case 38. Further, the cartridge 37 is configured to be opened toward the cartridge 37 side by a constant pressure.

For example, when cold water flows in, it flows to the first water purifier 33, but the pressure increases due to the life of the water purifier B, and hot water remaining in the switching tap A remains at a high temperature by any chance. When trying to flow into the water purification section d, the safety valve 27 is activated and hot water is discharged from the hot water drain hole 28.

A check valve 29 is biased toward the valve body by a spring 29a having one end connected to the valve body.

Here, referring to FIGS. 3, 4, and 9 to 11, regarding the flow of water of the switching plug A, the water purifier B is connected to the connection ports 2, 3 of the water treatment device connection fitting 1. It will be explained in the state where it is connected to.

When the operation lever 11 is operated to move to the position of the water purification mode shown in FIG. 1, the raw water flowing from the hot water supply pipe 22 and the water supply pipe 23 into the hot water supply flow passage 22a and the water supply flow passage 23a of the plug body 10 becomes the raw water. The hot water and the cold water reach the inside of the switching valve 9 through the same flow paths 22a and 23a.

Then, as shown in FIG. 9, since the hot water inflow hole 16 and the discharge hole 19 of the first valve body 9a are closed by the second valve body 9b of the switching valve 9, the second valve body 9a is closed. The inflow guide hole 20 and the outflow guide hole 21 of 9b communicate with the cold water inflow hole 17 and the water purification hole 18 of the first valve body 9a, respectively, and only the cold water passes through the water purification hole 18 It flows into the outward route 24a.

As shown in FIG. 4, the cold water further flows into the raw water inflow passage 31 of the outward connection tube b1 of the water purifier B from the purified water outward passage 24a through the outward connection port 2.

After that, the cold water flows into the first water purification unit 33 of the water purification unit d, passes through the first water purification unit 33 to be the primary purified water, and becomes the primary purified water. The same primary purified water is the second purified water. It flows into the cartridge 37 of the portion 34 and is secondarily purified by the hollow fiber membrane 36.

Then, the secondary purified water passes through the purified water outflow passage 32 of the reconnecting tube b2, from the return connection port 3 of the stopper body 10 to the discharge passage 14 of the discharge pipe 12 via the check valve 25. The water flows in and is discharged from the discharge port 13 as shown in FIG.

FIG. 10 shows a case where the operating lever 11 is operated to the upper position to stop the water, and the valve is closed. In this case, the inflow guide hole 20 of the second valve body 9b is blocked from communicating with the cold water inflow hole 17, so that the switching valve 9 is not supplied with water, so that the water is stopped.

On the other hand, when the operation lever 11 is operated to use the raw water, for example, when the hot water mode is set, the hot water supply pipe 22 and the water supply pipe 23 forming the raw water supply unit are used to supply hot water to the plug body 10. The hot water and the cold water as raw water that have flowed into the passage 22a and the water supply passage 23a reach the inside of the switching valve 9 from the passages 22a and 23a.

Then, as shown in FIG. 11, since the cold water inflow hole 17 and the water purification hole 18 of the first valve body 9a are closed by the second valve body 9b of the switching valve 9, the second valve body is closed. The inflow guide hole 20 and the outflow guide hole 21 of 9b communicate with the hot water inflow hole 16 and the discharge hole 19 of the first valve body 9a, respectively, and only the hot water passes through the discharge hole 19 to the discharge flow path 14. It flows in and is discharged from the discharge port 13.

Further, when stopping the water, the operation lever 11 may be positioned upward, as in the water purification mode.

In the hot and cold mixed water mode, if the second lever 9b of the switching valve 9 is operated by operating the operation lever 11 in the horizontal direction, the water purification hole 18 of the first valve 9a is closed. Then, the hot water inflow hole 16 and the cold water inflow hole 17 simultaneously communicate with the inflow guide hole 20 of the second valve body 9b, and the communication state between the hot water inflow hole 16 and the cold water inflow hole 17 can be adjusted by the operating lever 11. The mixture of hot water and cold water can be adjusted as desired to obtain the desired water temperature.

As described above, in order to detachably connect the water treatment device to the switching plug A, the connection ports 2 and 3 of the water treatment device connection fitting 1 on the switching plug A side are connected to the plug body 10 of the switching plug A. Since it is exposed to the outside, it can be easily connected even when the water treatment device such as the water purifier B is replaced with an external function product, and the connection ports 2 and 3 are provided downward from the plug body 10. Therefore, even if the cock is switched to the water treatment device side while the water treatment device such as the water purifier B is detached, the water that comes out will be received by the sink, and the water will fall on the user or the kitchen. The floor etc. will not be flooded.

In addition to the two connection ports 2 and 3 described above, the water treatment device connection fitting 1 can have more connection ports. By using the additional connection ports, a plurality of water treatment units can be used. It is also possible to use a physical processing device together.

As described above, since the connection ports 2 and 3 are detachably formed on the switching plug A in an exposed state, even though the switching plug A is used in cooperation with the water treatment device, the switching plug A A wide variety of water treatment equipment can be applied by simple work without replacing the water treatment equipment.Also, even if the water treatment equipment is not used temporarily or permanently, it is possible to use the closure attachment 26 etc. The function as A can be used while being satisfied.

Further, as a modification, as shown in FIG. 12, a flow path switching valve V made of a shape memory alloy is arranged below the forward and backward connecting cylinders b1 and b2, and the water purifier B is backwashed. There is something that made it possible.

When the operation lever 11 is set to the backwash mode shown in FIG. 1, the warm water inflow hole 16 and the water purification hole 18 of the first valve body 9a are connected to the second valve as shown in FIG. When communicating with the inflow guide hole 20 of the body 9b, the warm water flows into the raw water inflow passage 31 of the outward connection tube b1 and reaches the flow passage switching valve V. Then, the flow path switching valve V made of a shape memory alloy is activated by the temperature of the hot water, and the hot water flows to the second water purifying unit 34 as indicated by an arrow g in FIG. Then, after performing the cleaning action of the water purification section d, the flow goes to the check valve 29.

In this case, if the spring 29a of the check valve 29 is also made of a shape memory alloy that is set to shrink when hot water flows in, the hot water that has been washed passes through the check valve 29 and becomes a safety valve. 27, the safety valve 27 is opened toward the hot water drain hole 28 by the hot water as described in the previous embodiment, so that the hot water after cleaning is discharged from the hot water drain hole 28. Become.

Therefore, there is no concern that the user will accidentally use warm water after cleaning.

In this embodiment, the hot water is detected and the flow path switching valve V is operated to switch the flow path. However, a mechanical flow path switching unit that interlocks with the switching of the operation lever 11 may be separately provided. Conceivable.

Next, another embodiment is shown in FIGS. 14 to 16. In this, the water purifier B is arranged at the back of the water treatment device, and in this embodiment, the water treatment device connection fitting 1 is provided between the hot water supply pipe 22 and the water supply pipe 23.

Here, the structure of the water purifier B will be briefly described. The water purifier B includes a base portion e and a water purification portion d fitted into the base portion e.

Then, as shown in FIG. 14, the raw water inflow passage 31 is connected to the outward connection port 2 of the switching plug A, the purified water outflow passage 32 is connected to the return connection port 3, and the outward connection port 2 is connected. Is connected to the purified water return path 24a, and the return connection port 3 is connected to the purified water return path 24b.

When the water purifier B is not connected, a blind lid f may be attached to each of the connection ports 2 and 3, as shown in FIG.

As described above, by mounting the water purifier B on the back part of the switching plug A, the appearance is neat and compact, and the connection ports 2 and 3 are provided on the back part of the switching plug A. The connection ports 2 and 3 face the side opposite to the user, and even if the water purifier B or the like is left detached and the flow path is mistakenly switched to the water purifier B side, it does not affect the user.

Further, when the blind lid f is attached to the connection ports 2 and 3, it is located on the opposite side of the user, so that it does not spoil the appearance.

Instead of the water purifier B, another water treatment device such as an ion water purifier can be easily attached. This is because the connection ports 2 and 3 are exposed from the switching plug A when the water purifier B is removed, and if the switching plug A is connected to the inlet and outlet of the ionized water device. , A single switching lever 11 can be used to switch between still water, raw water, and ion water.

Although the connection ports 2 and 3 are provided so as to project in the above-described embodiments, they may be simple holes as shown in FIG.

In this case, the water treatment device side is formed so as to project. In any of the above-described embodiments, if a screwing means such as a nut n shown in FIG. 17 is provided, direct attachment is easy, and in particular, a heavy water treatment device such as an ion water regulator is attached. It is suitable for this. Of course, the connection between the connection ports 2 and 3 of the switching plug A and the water treatment device is not limited to direct attachment.

Another embodiment is shown in FIG.

This is because the electrolysis water purifier D is provided as a water treatment device in the switching tap A, and the operation and display of the operating state of the electrolysis water purifier D is displayed by the switching tap A. It is configured so that it can be done.

It should be noted that a small speaker may be provided and, for example, the above-mentioned mode display, failure / abnormality part display, instruction on handling, etc. may be displayed by a synthesized voice.

The status display section 42 allows the user to obtain various necessary information such as the current usage status and the electrode cleaning time.

Further, in this embodiment, an acidic water discharge port 43 is separately provided in the lower part of the stopper body 10 of the switching stopper A, and an acidic water flow path 44 communicating with the outlet port 43 is provided inside the stopper body 10. Furthermore, an auxiliary connection port 45 communicating with the flow path 44 is provided near the connection ports 2 and 3. An acid water outlet flow path 46 is connected to the auxiliary connection port 45.

Furthermore, a flow path switching valve Q that electrically opens and closes via a control unit G is provided in the middle of the purified water flow path 24 in which the return path connection port 3 communicates with the inside of the plug body 10. As will be described later, when the electrodes 54 and 55 of the electrolytic water purifier D are washed by applying a reverse voltage, the water after washing returning to the return port 3 is prevented from flowing to the outlet 13. It joins the water flow path 44 so that the acid water discharge port 43 can discharge the water.

Here, the configuration of the electrolytic water conditioner D and the flow of water will be described with reference to FIG.

The electrolyzing water conditioner D is divided into an electrolyzing tank 50, a partition wall 51 provided in the center thereof, an alkaline water tank 52 and an acidic water tank 53 defined by the partition wall 51, and water tanks 52, 53. It is composed of the electrodes 54, 55 provided.

Further, an alkaline water outlet 56 is formed in the upper part of the alkaline water tank 52, a raw water inlet 57 is formed in the lower part thereof, an acidic water outlet 58 is formed in the upper part of the acidic water tank 53, and a calcium water outlet is formed in the lower part. Each of the inlets 59 is formed, and the calcium from the separately provided calcium tank 63 is eluted into the calcium water inlet 59. 62 is a delivery pump for delivering calcium.

Then, an alkaline water outlet channel 60 and an acidic water outlet channel 46 are connected to the alkaline water outlet port 56 and the acidic water outlet port 58, respectively, and the alkaline water outlet channel 60 is connected to the plug for switching washing A. The return path connection port 3 provided in the main body 10 is communicated with, and the acidic water derivation flow path 46 is communicated with the auxiliary connection port 45.

Further, the electrode 54 provided on the alkaline water tank 52 side functions as a cathode during normal water conditioning operation, and the electrode 55 on the acidic water tank 53 side functions as an anode.

A desired forward voltage is applied to each of the electrodes 54 and 55 from the power source S for the electrolysis water rectifier D based on a control signal from the control unit G. The raw water is electrolyzed to generate alkaline water in the alkaline water tank 52 and acidic water in the acidic water tank 53.

The generated alkaline water passes from the alkaline water outlet 56 through the alkaline water outlet passage 60 to the return connection port 3 provided in the stopper body 10 of the switching stopper A, and then through the purified water passage 24. It can flow into the discharge flow path 14 via the check valve 25 and can be taken out from the discharge port 13.

Further, the acidic water passes from the acidic water outlet 58 through the acidic water outlet flow path 46 to the auxiliary connection port 45 provided in the stopper body 10 of the switching stopper A, and the acidic water communicating with the connection port 45. The water is discharged from the acidic water discharge port 43 through the water flow path 44.

Such acidic water can be used as washing water for hands and the like, paying attention to its astringent effect.

Further, since the acidic water discharge port 43 is located away from the discharge port 13 provided in the discharge pipe 12, the user will not mistake it for alkaline water.

By the way, a desired reverse voltage is applied to each of the electrodes 54, 55 from the power source S based on a control signal from the control unit G. This is decomposed, and this time, acidic water is produced in the alkaline water tank 52 and alkaline water is produced in the acidic water tank 53, whereby the deposits on the electrodes 54, 55 are dissolved and removed.

Regarding the post-washing water at this time, the water from the acidic water outlet 58 passes through the acidic water outlet flow path 46, and the auxiliary connection port 45 passes through the acidic water flow path 44 and is discharged from the acidic water discharge port 43.

On the other hand, the post-washing water from the alkaline water outlet 56 flows into the return connection port 3 through the alkaline water outlet channel 60.

At this time, the flow control valve from the control unit G shuts off the water purifying flow passage 24 in the flow passage switching valve Q arranged in the middle of the water purifying flow passage 24 communicating with the return passage connection port 3. The post-washing water flowing from the return connection port 3 flows into the acidic water flow passage 44 and joins with the post-washing water from the acidic water outlet 58. The acidic water discharge port 43 discharges the water.

At this time, in the status display section 42, the liquid crystal panel 42a has a display indicating that backwashing is in progress, and since it is possible to warn with a synthetic voice, it is possible to prevent accidental drinking of water after such washing. . In this embodiment, the acidic water is also discharged from the side of the switching washing A so that it can be used for hand washing and the like. However, an acidic water drain pipe is connected to the acidic water outlet 58 of the electrolytic water conditioner D. It is also possible to directly drain the water from the electrolyzer S.

In this case, since it is not necessary to provide the auxiliary connection port 45 and the acidic water spouting port 43 in the plug body 10 and the flow path switching valve Q is not necessary, the cost-effective switching plug A is used. be able to.

Further, in this case, the post-cleaning water from the acidic water outlet 58 is directly discharged, and the post-cleaning water from the alkaline outlet 56 is discharged from the discharge port 13 of the discharge pipe 12. In order not to be mistaken for water that can be used by the state display section 42, it is preferable to give a warning by a synthetic voice.
