Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hot and cold water mixing tap with a water purifier that is capable of supplying purified water from a water purifier in addition to spouting a mixture of hot water and water.

[0002]

[Prior Art]

 Hot and cold water mixers are widely used in kitchens and shower facilities to mix hot and cold water and spout mixed water or water at an appropriate temperature. This type of hot and cold water mixing tap is basically designed so that the temperature of the mixed water can be adjusted by adjusting the valve openings on the water side and the hot water side respectively. The valve mechanism of is incorporated.

A single-lever type has improved the usability of the hot and cold water mixing valve. This is a sliding valve built into the main body of the mixing tap, and by moving this valve two-dimensionally, the mixing ratio and flow rate of hot water and water can be adjusted. It is a structure in which such an operation is performed by one lever.

On the other hand, the expansion of facilities around water has progressed, and for example, facilities for kitchens have come to be used in which a water purifier is connected to a faucet so that purified water can be discharged. An example of connecting a water purifier to a convenient single lever type hot and cold water mixing tap is disclosed in Japanese Utility Model Laid-Open No. 2-121673. This is designed to open and close the flow path from the water supply pipe to the water purifier and the flow path from this water purifier to the water discharge pipe using a single lever for mixing hot water and water and adjusting the flow rate. is there.

[0005]

[Problems to be solved by the device]

 However, in the method disclosed in this publication, the operation of mixing the hot water and water, adjusting the flow rate, and switching to the purified water is performed with one lever, which further complicates the lever operation and makes the operation error-prone. For example, when you try to pour clean water into a cup, you spit out hot water.

Further, the sliding valve incorporated for mixing the hot water and the water and setting the flow rate also incorporates a structure for opening and closing the flow path to the water purifier, which complicates the valve structure.

As described above, in the structure in which the functions of the hot and cold water mixing valve and the water purifier are switched by using one lever, it is convenient, but it may cause a trouble in usability, and machining of the valve is also troublesome. There is a problem. Further, not only the single lever type but also a hot and cold water mixing tap having a plurality of knobs has the same problem.

The problem to be solved in the present invention is that the function as a hot and cold water mixing tap and the function as a water purifier can be easily used without erroneous operation, and a conventional valve can be used as it is. It is to simplify the structure.

[0009]

[Means for Solving the Problems]

 The present invention includes a valve unit that communicates with a water supply channel and a hot water supply channel and can set the mixing ratio of water and hot water and the flow rate of the mixed water, respectively, and a water discharge pipe provided downstream of the valve unit. In the provided hot and cold water mixing tap, a water purifier is provided in a path branched from the water supply passage, and a passage is connected from the water purifier to the water discharge pipe so that the water passage from the water supply passage to the water purifier is used for water purification. It is characterized by the provision of a water purification valve that can be opened and closed by the operation unit.

Further, the respective flow paths from the valve unit and the water purifier to the water discharge end of the water discharge pipe can be set as separate systems.

[0011]

[Action]

 When mixed water is required, the operation unit for the valve unit can be used to change the mixing ratio of water and hot water and the flow rate of mixed water so that it can be used like a conventional hot and cold water mixing tap. In addition, if a water purification valve is installed in the flow path branching from the water supply channel to the water purifier and operated by a water purification operation unit that is different from the operation unit for the mixing tap, the water from the water supply channel will operate the water purifier. After passing through, it becomes purified water and is sent to the water discharge pipe. Therefore, in order to properly use the mixed water and the purified water, the respective dedicated operation parts are used, and it is possible to avoid making a mistake in the operation.

[0012] Further, the water going to the water purifier is separated from the water supply passage before entering the valve unit, and the flow path up to the water discharge end of the water discharge pipe is divided into mixed water and purified water. It is also prevented from being contaminated by the flow path wall or the like.

【Example】

 FIG. 1 is a partially cutaway front view showing an embodiment of a hot and cold water mixing valve with a water purifier according to the present invention, FIG. 2 is a cross sectional view taken along the line AA of FIG. 1, and FIG. FIG. 4 is a schematic sectional view showing a flow system of water, hot water, mixed water, and purified water, taken along a line arrow.

In the figure, a water supply pipe 2 and a hot water supply pipe 3 are connected to a body 1 of the hot and cold water mixing valve, and a communication pipe 4 and a purified water which communicate with a flow path from the water supply pipe 2 and send water to a water purifier P. The reflux pipe 5 for returning the purified water from the vessel to the main body 1 is connected. A double-pipe water discharge pipe 6 is connected to the upper end of the main body 1, and a water discharge head 7 for separately discharging mixed water and purified water is attached to the tip thereof.

As shown in FIG. 3, the water discharge pipe 6 has a purified water flow passage 6a formed in the center thereof and a mixed water flow passage 6b provided around it. Further, the water spouting head 7 has a structure in which a purified water spouting port 7a and a mixed water spouting port 7b communicating with these two flow paths are separately provided.

FIG. 5 is a vertical sectional view showing the inside of the main body 1, and FIG. 6 is a horizontal sectional view taken along a plane including the axis of the main body 1.

At the right end of the main body 1, there is provided an operation lever 8 for mixed water for setting the mixing ratio of water and hot water from the water supply pipe 2 and the hot water supply pipe 3 and the flow rate of the mixed water sent to the water discharge pipe 6. .. In addition, at the left end of the main body 1, the flow path from the water supply pipe 2 to the communication pipe 4 is opened and closed, and the water supply is sent to the water purifier P and then the purified water is sent from the reflux pipe 5 to the water purification flow passage 6a of the water discharge pipe 6. An operating handle 9 for water purification is provided.

The operating lever 8 is connected to a hot water mixing valve unit 10 provided on the right side of the main body 1 to set a mixing ratio of water and hot water from the water supply pipes 2 and 3 and a flow rate to the water discharge pipe 6. I do. The valve unit 10 is similar to that used in a conventional single-lever type hot and cold water mixing valve, and includes a fixed valve plate 10b and a movable valve plate 10c superposed on the fixed valve plate 10b in a case 10a. This movable valve plate 10c is connected to the operation lever 8. The fixed valve plate 10b is provided with valve holes 10d and 10e capable of communicating with the water supply pipe 2 and the hot water supply pipe 3, respectively, and also with a mixed water valve hole 10f communicated with the mixing chamber 1a formed inside the main body 1. There is. Further, the movable valve plate 10c has inflow holes 10g and 10h that can be aligned and unaligned with the valve holes 10d and 10e of the fixed valve plate 10b, and a mixed water outflow hole 10i. Then, by moving the movable valve plate 10c by the operation lever 8, the degree of matching of the holes is changed, and the mixing ratio of the hot water and the water and the flow rate of the mixed water flowing from the mixed water valve hole 10f to the mixing chamber 1a. Can be changed.

The flow path from the water supply pipe 2 to the valve unit 10 branches off along the way, and communicates with the water purification chamber 1c by a communication flow path 1b provided in the main body 1 as shown in FIG. The water purification chamber 1c is provided with a water purification valve 11 which is operated by the water purification operation handle 9. This water purification valve 11 is one in which one end of a spindle 11a screwed into the water purification chamber 1c is connected to the water purification operation handle 9 and a valve body 11b is provided at the other end. The valve body 11b comes into contact with and separates from the valve seat 1d provided at the end of the communication channel 1b by turning the water purification operation handle 9, and functions as an on-off valve. The water purification chamber 1c communicates with a water purifier P by a communication pipe 4 connected to the lower end thereof, and the upper end of a reflux pipe 5 connected to the water purifier P has a water purification chamber formed inside the main body 1 separately from the mixing chamber 1a. It communicates with the chamber 1e. Then, as shown in FIG. 5, the water purification chamber 1e communicates with the water purification passage 6a of the water discharge pipe 6, and the mixing chamber 1a is connected to the water mixture passage 6b.

In the above configuration, when using mixed water, the valve body 11b of the water purification valve 11 is seated on the valve seat 1d by the water purification operation handle 9, and the flow path from the water supply pipe 2 to the water purifier P is closed. Keep it. When the movable lever plate 10c is moved by operating the operating lever 8, the matching degree of the inflow holes 10g, 10h of the movable valve plate 10c with respect to the valve holes 10d, 10e of the fixed valve plate 10b is changed and the flow path is opened. It Therefore, the mixed water is supplied from the mixed water outflow hole 10i through the mixed water valve hole 10f to the mixing chamber 1a through the hollow portion between the movable valve plate 10c and the fixed valve plate 10b. Then, the water is discharged from the mixing chamber 1a through the mixed water passage 6b of the water discharge pipe 6 and the mixed water discharge port 7b of the water discharge head 7.

On the other hand, in order to discharge purified water using the water purifier P, the flow path from the water supply pipe 2 and the hot water supply pipe 3 to the valve unit 10 is closed by the water purification operation handle 9 to perform the water purification operation. Turn the handle 9 to open the fresh water valve 11. As a result, the water from the water supply pipe 2 flows into the water purification chamber e through the communication flow path 1b and is sent from the communication pipe 5 to the water purifier P. Therefore, the water passes through the water purifier P and then flows into the water purification chamber 1e in the main body 1 from the reflux pipe 5, passes through the water purification passage 6a of the water discharge pipe 6, and then from the water purification outlet 7a of the water discharge head 7. Is ejected.

It is also possible to perform an operation of using the mixed water and the purified water at the same time. In this case, the mixed water is discharged from the mixed water discharge port 7b via the valve unit 10 by the operation lever 8 as described above, and at the same time, if the water purification valve 11 is opened by the water purification operation handle 9, the water purification discharge port is opened. Purified water is obtained from 7a. At this time, since the mixed water and the purified water have separate flow paths to the discharge end, the mixed water does not mix with the purified water. Further, since the purified water spouting port 7a of the spouting head 7 and the mixed water spouting port 7b are displaced from each other in the front and rear, while pouring the mixed water into a bowl placed in a kitchen sink, for example, pour the purified water into the cup. You can also

As described above, since the main body 1 of one hot and cold water mixing stopper is provided with the operation lever 8 for mixed water and the operation handle 9 for purified water when using purified water, the operation is performed when the mixed water and purified water are used separately. You won't be confused by. In particular, compared to the conventional example in which the temperature and flow rate of the mixed water is set with a single lever handle, and switching to purified water spouting is also made, there is no mistake in operation and it can be easily used by elderly people and children. become.

Furthermore, since the purified water is completely unrelated to the flow path of the mixed water downstream of the valve unit 10, the purified water sent from the water purifier P is not contaminated by the mixed water, water supply, hot water supply, or the like. Therefore, whether the pure water is used alone or the purified water and the mixed water are used at the same time, the cleanliness of the purified water is not affected and the function of the water purifier P can be sufficiently fulfilled.

In the embodiment, the operation part for the hot and cold water mixing tap is one operation lever 8 and the operation part for the water purifier P is also one operation handle 9 for water purification. It goes without saying that a rotary type, push-button type or self-closing type operation unit may be used as long as the setting and opening / closing of the flow path can be performed.

[0026]

[Effect of the device]

 In the present invention, since the operation unit for mixed water and the operation unit for purified water are separately provided, mixed water or purified water can be obtained without making a mistake in the operation, and it can be easily used by children and the elderly.

Further, if the water purifying valve operated by the water purifying operation unit is provided as a system separate from the flow path of the mixed water, and the flow path to the water discharge end is separated from the flow path of the mixed water, the water is passed through the water purifier. The purified water will not be contaminated by mixed water or scales adhering to the flow path. Therefore, even if the water purifier and the hot and cold water mixing tap are used together, the purified water purified by the water purifier will not be affected and the function of the water purifier will not be impaired.
