DETAILED DESCRIPTION OF THE INVENTION
1 to 5 show an embodiment of the present invention.
First, in FIG. 1 to FIG. 3, a hot water mixing tap 1 with a water purification function is a mixing plug main body that appropriately mixes hot water and water flowing in from a hot water supply pipe H and a water supply pipe C and supplies the mixed water to the mixed water supply pipe 2a. 2, mixed water supplied from the mixing plug body 2, or raw water made of water, a shower head 3 for discharging the purified water, and a flexible pipe 4 connecting the shower head 3 and the mixed water supply pipe 2 a. And have. The flexible tube 4 forms a raw water supply channel 100 (see FIG. 5).
[0006]
2b and 2c are supply pipes connected to the hot water supply pipe H and the water supply pipe C, respectively, and 2d is an operation lever for adjusting the mixing ratio of hot water supplied to the mixed water supply pipe 2a and the amount of water discharged including water stoppage. It is.
[0007]
The shower head 3 is supported by a shower holder 3a through which the flexible tube 4 can be inserted, and can be pulled out from the tip 3b of the shower holder 3a. The flexible tube 4 drawn out from the lower end of the shower holder 3a is connected so as to communicate with 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.
[0008]
The characteristic configuration of the present invention will be described below.
[0009]
The shower head 3 includes a synthetic resin grip 11 in which a cylindrical water purification cartridge 10 is interchangeably incorporated, and a synthetic resin water outlet connected to the downstream end of the grip 11 by screwing. It consists of a main body 12. The water purification cartridge 10 has, for example, a high-performance antibacterial fiber activated carbon filter 13. 14 is a through hole of the water purification cartridge 10 and is located on the axis A of the water purification cartridge 10. The through hole 14 forms a raw water channel 101 (see FIG. 5) that communicates with the water supply channel 100.
[0010]
The spout main body 12 has a raw water opening 20 communicating with the raw water flow channel 101 on the axis A at the upstream end, and a water purification opening 21 immediately below the raw water opening 20 at the upstream end. The water purification opening 21 communicates with an annular water purification passage 102 formed outside the water purification cartridge 10. That is, in the clean water discharge state, the annular space S formed between the inner peripheral surface m from the grip portion 11 of the shower head 3 to the spout main body 12 and the outer peripheral surface n of the filter 13 is filtered by the filter 13. The purified water flows out to the purified water opening 21.
[0011]
In this clean water discharge state, as shown in FIG. 5 (B), an opening 33 for connecting the raw water passage 101 and the water discharge passages P, P ′, Q described later is closed by a valve body 41 described later. Accordingly, the raw water flowing from the water supply channel 100 to 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 raw water is fed into the filter 13 by the water pressure on the water supply channel 100 side The purified water flowing in the radial direction of the water purification cartridge 10 and filtered by the filter 13 reaches the chamber 31 that forms the water discharge flow paths P, P ′, Q from the water purification flow path 102 through the water purification opening 21 and discharges water. . The water purification opening 21 is always in communication with the chamber 31.
[0012]
On the other hand, when the purified water discharge state is switched to the raw water discharge state, as shown in FIG. 5 (A), the closed opening 33 is opened, and the raw water in the through hole 14 passes through the raw water opening 20. The water reaches the chamber 31 and discharges 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 reservoir of raw water. However, since the water pressure on the side of the water supply channel 100 is large, most of the raw water that has passed through the raw water opening 20 flows directly into the chamber. Further, even when the raw water flows through the through hole 14 of the water purification cartridge 10, the water pressure on the water supply channel 100 side is large, and the raw water opening 20 and the opening communicate with each other. The penetration rate is very small.
[0013]
Reference numeral 22 denotes a synthetic resin water discharge cap that is screwed to the lower side of the water discharge main body 12 and forms a water discharge flow path P ′ for direct discharge of purified water and a water discharge flow path P ′ for direct discharge of raw water at the center. While having the water mouth part 23, it has the water outlet part 28 which forms the water outlet channel Q for sprinkling raw | natural water around the water outlet part 23, and the water outlet channel (not shown) for watering purified water. The water outlet 23 is provided with, for example, a plurality of water spray plates 27 each having a mesh bordered with a synthetic resin material. A water spray plate 30 is also provided at the water outlet 28. Further, the water discharge channels P, P ′ and the water discharge channel Q for water spraying are configured to be switchable.
[0014]
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.
[0015]
The switching means includes a seesaw-type switching operation tool 40 for switching which is exposed on the lateral side portion of the water discharge body 12. That is, as shown in FIG. 4, the rotary operation tool 40 has a switching display unit 80 on the front surface that allows easy visual inspection of whether the water is in a clean water discharge state or a raw water discharge state. The switching display unit 80 includes a display portion 80a indicating a purified water discharge state and a display portion 80b indicating a raw water discharge state.
[0016]
Further, the switching means has a chamber 31 for forming the water discharge channels P, P ′, Q on the lower side of the water discharge body 12, while the original space in the space S ′ on the upper side of the water discharge body 12 is the original. A valve seat member 34 having an opening 33 for communicating the water passage 101 with the water discharge passages P, P ′, and Q, and interlocking with the turning operation of the turning operation tool 40 on the valve seat member 34. The valve body holding member 42 that holds the valve body 41 that opens and closes the water discharge flow paths P, P ′, and Q is provided.
[0017]
That is, as shown in FIG. 4, the upper surface plate 34 a of the valve seat member 34 is provided with an opening 33 for communicating the raw water channel 101 and the water discharge channels P, P ′, Q in correspondence with the chamber 31. The valve body holding member 42 made of a synthetic resin is provided in a space portion on the upper side of the water discharge body 12 so as to be rotatable around a vertical axis, and the valve body holding member 42 is provided with the valve body holding member 42. A metal ball valve element 41 that opens and closes the opening 33 in accordance with the rotation is provided by being biased in the valve closing direction by a spring 45. Further, the rotating operation tool 40 is connected to the valve body holding member 42, and the operation tool 40 is exposed to the lateral side portion of the spout main body 12. The spring 45 and the ball valve body 41 are inserted into the cylindrical body 55 from the lower side in this order.
[0018]
The rotation shaft 40 of the rotation operation tool 40 has a pin 50 standing on the upper surface plate 34 a of the valve seat member 34, and the rotation operation tool 40 according to the shape of the pin 50 so as to be fitted and engaged with the pin 50. And a hole 40a drilled in.
[0019]
Reference numeral 51 denotes a groove for the ball valve element 41 provided in parallel with the opening 33 on the upper surface plate 34 a of the valve seat member 34. That is, in the raw water discharge state shown in FIGS. 5A and 5C, the opening 33 is not covered with the ball valve body 41, and the ball valve body 41 remains in the groove 51. . On the other hand, when the rotation operation tool 40 is switched from the raw water discharge state to the purified water discharge state shown in FIG. 5B, the ball valve element 41 is moved from the groove 51 to the opening 33 in conjunction with the operation of the rotation operation tool 40. The valve body holding member 42 is rotated so as to move to the right.
[0020]
Thus, the rotating operation tool 40 is not a push button 81 method for determining whether the water is in a clean water discharge state or a raw water discharge state in a recessed state as in the prior art, but a seesaw type using the pin 50 as a fulcrum portion. Therefore, in the raw water discharge state, the display portion 80b is recessed and the display portion 80a protrudes, and it can be easily determined whether it is in the clean water discharge state or the raw water discharge state by visual observation. The same applies to the case of clean water discharge.
[0021]
In addition, as a transmission mechanism for transmitting the switching operation of the rotation operation tool 40 to the valve body 41, a simple configuration including a valve body holding member 42, a ball valve body 41, a spring 45, and a valve seat member 34 is provided. Because it is adopted, it is unlikely to cause a failure, and even if it fails, the number of parts is small, so it can be replaced quickly.
[0022]
【The invention's effect】
As described above in detail, the present invention can easily determine whether it is the purified water discharge mode or the raw water discharge mode simply by visual observation, and has an effect of providing a hot and cold water mixing faucet with a water purification function that is unlikely to fail.
