First, in FIGS. 1 to 3, a hot water mixing tap with a water purification function 1 is a mixing tap main body that appropriately mixes hot water and water flowing from a hot water supply pipe H and a water supply pipe C and supplies mixed water to a mixed water supply pipe 2 a. 2, a shower head 3 for discharging mixed water supplied from the mixer tap main body 2 or raw water or purified water, and a flexible tube 4 for connecting the shower head 3 and the mixed water supply pipe 2a. And The flexible tube 4 forms a water supply channel 100 for raw water (see FIG. 5).

2b and 2c denote a hot water supply pipe H and a water supply pipe C, respectively.
And a control lever 2d for adjusting the mixing ratio of hot and cold water supplied to the mixed water supply pipe 2a and the amount of water discharge including stop water.

The shower head 3 is supported by a shower holder 3a through which a flexible tube 4 can be inserted, and can be pulled out from a tip 3b of the shower holder 3a. The flexible tube 4 pulled out from the lower end of the shower holder 3a is connected to the mixed water supply tube 2a while passing through the guide 5. Reference numeral 6 denotes a weight provided in the middle of the flexible tube 4.

Hereinafter, a characteristic configuration of the present invention will be described.

The shower head 3 has a grip portion 11 made of a synthetic resin in which a cylindrical water purification cartridge 10 is exchangeably housed, and a synthetic resin connected to a downstream end of the grip portion 11 by screwing. Of the water outlet body 12. The water purification cartridge 10 has, for example, a high-performance antibacterial fiber activated carbon filter 13. Reference numeral 14 denotes a through hole of the water purification cartridge 10, which is located on the axis A of the water purification cartridge 10. The through hole 14 forms a raw water flow path 101 (see FIG. 5) communicating with the water supply flow path 100.

The water outlet body 12 has a raw water opening 2 communicating with the raw water flow path 101 on the axis A at the upstream end.
0 and an opening 21 for water purification just below the opening 20 for raw water at the upstream end. This opening for water purification 21
Communicates with an annular water purification channel 102 formed outside the water purification cartridge 10. That is, in the purified water spouting state, the inner peripheral surface m from the grip portion 11 of the shower head 3 to the spout body 12 and the outer peripheral surface n of the filter 13
The purified water filtered by the filter 13 in the annular space S formed therebetween flows out to the water purification opening 21.

In this purified water spouting state, as shown in FIG. 5 (B), an opening 3 for communicating a raw water flow passage 101 with water spouting channels P, P ', Q described later by a valve body 41 described later.
3 is closed, the raw water flowing from the water supply flow path 100 through the through hole 14 of the water purification cartridge 10, that is, the inside of the filter 13 makes a U-turn at the raw water opening 20, and the water pressure on the water supply flow path 100 side Raw water flows from inside the filter 13 in the radial direction of the water purification cartridge 10, and purified water filtered by the filter 13 flows from the water purification flow path 102 through the water purification opening 21 to the water discharge flow paths P,
Water is discharged to the chamber 31 where P 'and Q are formed. The water purification opening 21 is always in communication with the chamber 31.

On the other hand, when the state is switched from the purified water spouting state to the raw water spouting state, as shown in FIG. 5A, the closed opening 33 is opened, and the raw water in the through-hole 14 passes through the raw water opening 20. The water passes through the chamber 31 to discharge water. In this case, since the water purification opening 21 is always in communication with the chamber 31, the raw water that has passed through the raw water opening 20 flows into the annular space S via the water purification opening 21 and becomes a pool of raw water. However, since the water pressure on the water supply flow path 100 side is large, most of the raw water passing through the raw water opening 20 directly flows into the chamber. Also, at the time when the raw water flows through the through hole 14 of the water purification cartridge 10, the water pressure on the water supply flow path 100 side is large, and the raw water opening 20 communicates with the opening. The penetration rate is extremely small.

Reference numeral 22 denotes a water discharge cap made of synthetic resin screwed to the lower side of the water discharge port main body 12, and a water discharge flow path P 'for directly discharging purified water and a water discharge flow path P' for directly discharging raw water are provided at the center. While having the water discharge port 23 formed, it has a water discharge port 28 which forms a water discharge flow path Q for sprinkling raw water and a water discharge flow path (not shown) for spraying purified water around the water discharge port 23. The water outlet 23 is provided with, for example, a plurality of water spray plates 27 bordering a mesh with a synthetic resin material. Further, a sprinkling plate 30 is also provided at the water outlet 28. Further, the water discharge channels P and P 'for direct discharge and the water discharge channel Q for watering are switchable.

Next, the switching means for switching between the raw water discharge state and the purified water discharge state will be described with reference to FIGS.

The switching means includes a seesaw-type switching operation tool 40 exposed on the lateral side of the water outlet main body 12. That is, as shown in FIG.
Has a switching display section 80 on the front face thereof, which allows the user to easily visually check whether the state is a pure water spouting state or a raw water spouting state. The switching display section 80 includes a display section 80 that indicates a purified water discharge state.
a and a display portion 80b indicating the raw water discharge state.

Further, the switching means has a chamber 31 for forming the water discharge passages P, P ', Q on the lower side of the water outlet main body 12, while being provided in the space S' on the upper side of the water outlet main body 12. , The raw water flow path 101 is connected to the water discharge flow paths P, P ′,

Are inserted into the cylinder 55 in this order from below.

The turning shaft of the turning operation tool 40 is rotated in accordance with the shape of the pin 50 so as to fit and engage with the pin 50 erected on the upper surface plate 34a of the valve seat member 34. And a hole 40a formed in the operation tool 40.

Reference numeral 51 denotes a groove for the ball valve element 41 provided in the upper surface plate 34a of the valve seat member 34 in parallel with the opening 33. That is, in the raw water discharge state shown in FIGS. 5A and 5C, the opening 33 is not covered by the ball valve 41, and the ball valve 41 remains in the groove 51. . On the other hand, the turning operation tool 40 is moved from the raw water discharge state to the position shown in FIG.
When the switching operation is performed to the purified water discharge state shown in (B), the valve body holding member 42 rotates so that the ball valve body 41 moves from the groove 51 to the opening 33 in conjunction with the operation of the rotating operation tool 40.

The rotating operation tool 40 does not use the push button 81 for judging whether it is in the clean water discharge state or the raw water discharge state according to the recessed state as in the prior art. Because it is configured in a seesaw style,
In the raw water spouting state, the display portion 80b is depressed and the display portion 80a protrudes, so that it can be easily determined only by visual observation whether the state is the pure water spouting state or the raw water spouting state. The same applies to the case of the clean water spouting state.

As a transmission mechanism for transmitting the switching operation of the rotary operation tool 40 to the valve body 41, a valve body holding member 42 is provided.
