To be supplied freely mixed water to.

A number of embodiments of the shower head with a water purifying function attached to the mixing faucet 2 of the sink 1 will be described below.
[First embodiment]
〔Constitution〕
The shower head 10 with a water purification function used here is attached to the hose 3 of the mixing faucet 2 so that it can be used as a shower head used in a kitchen sink, as shown in the external views of FIGS. A grip portion 11 having an end portion that can be formed, and a head portion 12 integrally provided with a shower discharge port 12a at an end portion of the grip portion 11 opposite to the hose attachment side.

  The gripping part 11 is divided into a cylinder part 11a on the head 12 side and a cylinder part 11b on the hose attachment side at the intermediate part, and a relay screw part 11c is provided so that these can be detachably and integrally combined. The cartridge 11 for water purification (see FIGS. 5 and 6) can be accommodated inside the gripping part 11 by releasing the screwing of the relay thread part 11c and separating the cylindrical part 11a and the cylindrical part 11b. In addition, a thick cylindrical hose connection portion 11f provided with a hose attachment screw 11d is formed at the end portion on the hose attachment side to facilitate attachment / detachment with the hose.

  On the head 12, a flow path switching push button 13 protrudes at a position opposite to the gripping section 11, and a flat shower discharge port 12 a is formed at a position rotated approximately 90 degrees from the push button placement position. The straight discharge port 12b is formed at the center of the shower discharge port 12a. And the switching lever 14 which switches the discharge from the straight discharge port 12b and the discharge from the shower discharge port 12a to the downstream side nearest the arrangement | positioning position of the push button 13 from the surface which forms the shower discharge port 12a Protrusions are arranged.

As shown in FIGS. 5 to 7, the shower head 10 with a water purification function houses a water purification cartridge 15 inside the grip portion 11.
In the gripping part 11 that accommodates the water purification cartridge 15, the outer peripheral flow path 21 of the water purification cartridge 15 is a part of the raw water flow path, and the central space 22 of the water purification cartridge 15 is a part of the water purification flow path. Use as part.

  The water purification cartridge 15 includes a water purification material 15a formed in a cylindrical shape by providing a hole (central space portion 22) concentrically with the central axis, and filters 15b, 15c made of nonwoven fabric, sponge, nets, or the like on the downstream side. The sterilized ceramic 15d in the form of particles or pellets sandwiched between the two is accommodated in two spaces formed by caps 15e, 15f, 15g divided into three parts.

  And it has a cap 15e formed in a cylindrical shape with a bottom having a large number of slits on the peripheral wall, and a water purification material support wall having a surface perpendicular to the axial direction in which a hole serving as a fluid passage is formed in the center of the cylindrical shape. The water purification material 15a is accommodated in a space provided by a cap 15f having a fitting portion with the other cap 15e, 15g at each end.

  Further, two cylinders having different diameters from the cap 15f are connected by a wall surface perpendicular to the axial direction, and a fitting portion with the cap 15f is formed on the larger diameter cylinder of the two cylinders, and the smaller diameter cylinder is formed. Sterilization ceramic 15d sandwiched between filters 15b and 15c in the inner space of a large-diameter cylinder provided by a cap 15g formed with a fitting portion with a cartridge receiver 11e (described later) provided on the head 12 side. To accommodate.

  The water purification material 15a to be contained is made of activated carbon as a main component and hardened in a cylindrical shape. When mixed water permeates between the cylindrical outer peripheral surface and the center hole, chemical components dissolved in water and Floating fine solid substances are adsorbed or filtered.

  In addition, the sterilizing ceramic 15d is obtained by adsorbing silver or copper or the like on the surface of a mixture obtained by mixing zinc oxide, montmorillonite, etc. with calcium phosphate as a base material and sintering it in a granular or pellet form. Adsorbs and sterilizes and releases metal ions to sterilize or sterilize harmful bacteria in the water, thereby detoxifying the water quality.

A cylindrical cartridge receiver 11e for inserting and fixing the tip of the water purification cartridge 15 (the end on the small diameter side of the cap 15g) protrudes from the inner end of the cylinder 11a on the head 12 side of the grip 11. To do.
By inserting the small diameter end of the cap 15g of the water purification cartridge 15 into the cartridge receiver 11e, the position of the water purification cartridge 15 is fixed.

  An O-ring 15h is provided on the peripheral surface of the small diameter end of the cap 15g. When the cap 15g is inserted into the cartridge receiver 11e, leakage is stopped by the O-ring 15h that is in close contact with the inner peripheral surface of the cartridge receiver 11e.

  The flow path 23 on the outer peripheral side of the cartridge receiver 11e communicates with the outer peripheral flow path 21 of the water purification cartridge 15 and is used as a part of the raw water flow path. Further, the flow path 24 on the inner surface side of the cartridge receiver 11e. Is communicated with the central space 22 of the water purification cartridge 15 via the sterilizing ceramic 15d, and is used as a part of the water purification flow path.

  Thereby, in the case of water purification discharge, the mixed water that has flowed into the gripper 11 passes through the water purification material 15a of the water purification cartridge 15 from the outer peripheral side flow path 21 of the water purification cartridge 15 to purify the water quality. Then, it flows into the central space portion 22 of the water purification material 15a, passes through the filter 15b, the sterilizing ceramic 15d, and the filter 15c to be sterilized or sterilized to render the water quality harmless, and then the flow path on the inner surface side of the cartridge receiver 11e. It flows out to the head 12 side via 24 and is discharged from the head 12 to the outside.

Further, in the case of discharging raw water, the water passes through the outer peripheral side flow path 21 of the water purification cartridge 15 and flows out to the head 12 side through the outer peripheral side flow path 23 of the cartridge receiver 11e. To discharge.
In the case of this raw water discharge, since the mixed water passes through the flow path 21 formed on the outer peripheral side of the water purification cartridge 15, clogging that adheres to the surface of the water purification material accumulated during the purification water discharge is caused. Fine solid substances and the like are washed away so that clogging is less likely to occur during purification discharge, and the purification ability of the water purification material 15a is maintained at a high level and the life is extended.
In particular, when hot water is discharged into the raw water, the higher the hot water temperature, the more effectively the activated carbon, which is the main component of the water purification material 15a, releases trihalomethane, metal ions, etc. adsorbed at the time of water discharge. And the regeneration effect of activated carbon can be enhanced.

As shown in FIGS. 5, 6, and 8 to 12, the shower head 10 with a water purification function projects a push button 13 and a switching lever 14 on the head 12.

[Function and effect]
In the embodiment configured as described above, by operating the push button 13 incorporated in the head 12, the purified mixture is obtained when the push button 13 protrudes from the head 12 (shallow push amount). The raw water flows out in a state where the amount of water that has flowed out and the push button 13 has entered and protruded from the head 12 is small (a deep pushing amount).

  First, when the mixed water purified with a shallow pushing amount is flowing out as shown in FIGS. 8 to 10 and 12, the push button 13 is set so as to have a deep pushing amount as shown in FIGS. 26 to 28. When the button is pressed, the second switching top 13d that is in contact with the push button 13 presses the first switching top 13c and transmits a pressing force from the first switching top 13c to the switching shaft 13a to resist the urging force of the coil spring 53. Then, the switching shaft 13a is moved in the direction approaching the side wall of the partition member 12c.

  At this time, when the first switching top 13c slides in the groove of the switching ring 13b and moves until it disengages from the groove, the first switching top 13c pushed by the second switching top 13d becomes the second switching top 13d. According to the shape of the contact portion with the first switching top 13c, it moves so as to change the direction of close contact and rotates as a result, changing the relative position between the first switching top 13c and the end face 36b of the switching ring 13b, The shut-off valve 16 is opened and the shut-off valve 17 is closed to switch to the outflow of raw water.

  The shut-off valve 16 is opened, the shut-off valve 17 is closed, the switching shaft 13a is returned by the amount of play by the biasing force of the coil spring 53, and the end of the rib provided on the first switching top 13c is engraved on the switching ring 13b. When the position is fixed by coming into contact with the shallow groove side, the mixed water flowing out becomes raw water.

  The push button 13 is pushed again, and the pressing force is transmitted from the second switching top 13d in contact with the push button 13 to the first switching top 13c and further to the switching shaft 13a, thereby resisting the biasing force of the coil spring 53. When the switching shaft 13a is moved in the direction close to the side wall of the partition member 12c, the end of the rib provided on the first switching top 13c is engaged with the shallow groove 36a (361) formed in the switching ring 13b. And the first switching top 13c pushed by the second switching top 13d moves so as to change the direction of contact according to the shape of the contact portion between the second switching top 13d and the first switching top 13c. And the relative position between the first switching top 13c and the end face 36b of the switching ring 13b is changed.

  As a result, as shown in FIGS. 8 to 10, the rib 43 provided in the first switching top 13 c enters the deep groove 36 a (362) in the axial direction of the switching ring 13 b, and the first biasing force of the coil spring 53 causes the first The rib 43 provided on the switching top 13c is slid along the groove of the switching ring 13b in a direction away from the side wall of the partition member 12c, and the switching shaft 13a in contact with the first switching top 13c is partitioned. It moves to the direction away from the side wall of the member 12c, the shutoff valve 16 is closed, the shutoff valve 17 is opened, and it switches to the outflow of purified water.

When the purified water flows out, as shown in FIG. 12, it passes through the valve seat 17a of the shutoff valve 17 and flows out to the valve downstream side flow path 20, and the purified water flow path from the valve downstream side flow path 20 through the purified water conduit 65. The water is discharged from the purified water discharge port 19 formed at the lower end of 62.
When the raw water flows out, as shown in FIGS. 26 to 28, it passes through the valve seat 16 a of the shutoff valve 16 and flows out into the valve downstream space 18, and is switched from the valve downstream space 18 via the collective passage 25. Shower discharge or straight discharge specified by the lever 14 is performed.

  When discharging raw water, when the shower is discharged, the valve body 26a is straightened by operating the switching lever 14 and rotating the valve body 26a about the shaft portion 26b independently of the operation of the push button 13. The mixed water coming out of the inlet portion of the discharge port 12b and coming out of the collecting passage portion 25 flows into the inlet portion of the straight discharge port 12b and is discharged straight.

  Further, when the raw water is discharged straight, when the switching lever 14 is operated in the opposite direction and the valve body 26a is rotated in the reverse direction about the shaft portion 26b, the valve body 26a becomes the straight discharge port 12b. The mixed water generated from the collecting passage 25 is prevented from flowing into the inlet of the straight discharge port 12b, the flow path is changed to the shower discharge port 12a, and flows into the shower side space 18a. The shower is discharged from the shower discharge port 12a.

  In such a 1st Example, since the purified water discharge port 19 is formed in the shower discharge port formation area separately from the raw water discharge flow path, it can be easily distinguished from the raw water discharge and at the time of purified water discharge, It can be used without switching between straight discharge and the operation becomes easy, and the discrimination and operability can be improved.

  Further, the size restriction on the flow path switching valve composed of the shut-off valves 16 and 17 for switching the water quality can be expanded to a range that can be incorporated into the head 12, and the size restriction of the flow path switching valve. Since the flow path switching valve can be operated on the head 12 side, the operability is improved, and the weight distribution between the head 12 and the grip portion 11 can be distributed in a well-balanced manner. The shape and structure can be well balanced in handling.

  By incorporating the water purification cartridge 15 in the grip 11, a part of the raw water flow path can be formed on the outer peripheral side of the water purification cartridge 15, and the water quality purification provided in the water purification cartridge 15 from this raw water flow path. A part of the purified water flow path that reaches the central space 22 formed in the center via the material 15a can be formed, the flow path configuration can be simplified and compact, and the structure of the gripping part 11 is simplified. More contents of the water purification material 15a can be stored.

  The flow path upstream of the water purification material 15a is a shared flow path for raw water and purified water, and solid substances and other accumulated substances that cause clogging accumulated during the purification water discharge can be washed away during the raw water discharge. It is possible to make clogging difficult and extend the life of the water purification material 15a.

  A water purification cartridge 15 is incorporated in the gripping part 11, and a flow path switching valve is incorporated in the head part 12. The flow path can be simplified, the weight distribution is good, and the shower head has a very good balance in handling. It becomes light and cheap.

  The flow path switching valve protrudes from the head 12 because the shut-off valve 16 for raw water and the shut-off valve 17 for water purification are alternately switching shut-off valves that alternately shut off the flow path by the same push button 13. By pushing the push button 13, it is possible to switch between clean water and raw water and improve operability.

  Moreover, since the shut-off valve 16 for raw water and the shut-off valve 17 for purified water are spherical valve bodies 16b and 17b, respectively, the water pressure applied to the spherical valve bodies 16b and 17b when the valves are closed is as follows: Together with the urging force of the coil springs 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, so that the sealing can be ensured.

Since the discharge switching valve 26 is a lever-operated cutoff valve formed in the flow path provided downstream of the raw water side cutoff valve 16 among the flow path switching valves, Either straight discharge can be easily selected, and high convenience can be maintained.
If the inflow path to the flow path switching valve is changed so that the shutoff valve 16 side is the purified water side and the shutoff valve 17 is the raw water side, a flow path that can be switched between shower discharge and straight discharge is provided on the purified water side. Can be configured.
In this embodiment, the flow path switching valve is provided with the two shutoff valves 16 and 17, but the flow path may be switched with one shutoff valve.
This shower head 10 with a water purifying function can be used not only in a kitchen but also in a washroom, a bathroom, etc., and has very high versatility.

[Function and effect]
In the third embodiment configured as described above, the push button 13 incorporated in the head 12 is operated, and the push button 13 is purified in a state where it protrudes from the head 12 (shallow push amount). In a state where the mixed water flows out from the purified water discharge port 319 and the push button 13 enters the head 12 and the amount of protrusion is small (deep push amount), the switch lever 14 is operated to turn the discharge switch valve 26 on. By selecting the shower discharge or the straight discharge, the raw water flows out from the shower discharge port 12a or the straight discharge port 12b.

  First, when the push button 13 has a shallow push amount, the raw water-side shut-off valve 16 is closed, and the purified water-side shut-off valve 17 is open so that the purified mixed water flows out, the push button 13 is made deep. When pushed in, the shutoff valve 16 is opened, the shutoff valve 17 is closed, and switching to discharge of raw water is performed. When the push button 13 is pushed again from this state and the push button 13 is changed to a shallow push amount, the shutoff valve 16 is closed and the shutoff valve 17 is opened to switch to discharge of purified water.

  At the time of discharge of purified water, it passes through the valve seat 17a of the shut-off valve 17 and flows out to the valve downstream side flow path 20 formed by the purified water conduit 65 and the flow path forming member 313a of the partition member 313, and raw water through the opening 313c. Cylinder that protrudes from the valve downstream side channel 320 through the purified water channel 319a and from the head 12 through the purified water side valve downstream channel 320 formed along the outer periphery of the valve downstream space 18 It discharges from the purified water discharge port 319 projected in the part 11a.

  Further, at the time of discharging raw water, similarly to the case of the first embodiment, it passes through the valve seat 16a of the shutoff valve 16 and flows out into the valve downstream side space 18, and from the valve downstream side space 18 through the collecting passage 25. The shower discharge or straight discharge selected by the switching lever 14 is performed.

  In this case, when shower discharge is performed, when the switching lever 14 is operated to rotate the valve body 26a around the shaft portion 26b independently of the operation of the push button 13, the valve body 26a is moved to the straight discharge port. The raw water coming off from the inlet portion of 12b and flowing out of the collecting passage portion 25 flows into the inlet portion of the straight discharge port 12b and is discharged straight.

  Further, when the straight discharge is performed, the switching lever 14 is operated in the opposite direction to rotate the valve body 26a in the reverse direction about the shaft portion 26b, so that the valve body 26a is brought into the inlet portion of the straight discharge port 12b. The raw water entering and flowing out from the collecting passage 25 is prevented from flowing into the inlet of the straight outlet 12b, the flow path is changed to the shower side space 314, and the shower side space 314 is passed through the shower outlet 12a. The shower comes out.

  In such a 3rd Example, since the purified water discharge port 319 is provided in the cylinder part 11a of the holding part 11, distinction with purified water discharge and raw | natural water discharge can be performed easily, and discharge switching is performed in purified water discharge. Since the discharge can be performed without any problems and the operability is improved, the distinguishability, visibility and operability are improved.

  Further, since the raw water shut-off valve 16 and the water purifying shut-off valve 17 of the flow path switching valve are alternately switched shut-off valves for alternately shutting off the flow path by the same push button 13, it protrudes from the head 12. By pressing the push button 13, the purified water and the raw water can be switched and used, and the operability can be further improved.

  Moreover, since the shut-off valve 16 for raw water and the shut-off valve 17 for purified water are spherical valve bodies 16b and 17b, respectively, the water pressure applied to the spherical valve bodies 16b and 17b when the valves are closed is as follows: Together with the urging force of the coil springs 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, and can be reliably sealed.

Since the discharge switching valve 26 is formed in a flow path provided downstream of the raw water side shut-off valve 16 among the flow path switching valves, the raw water side shut-off valve 16 is opened. In this case, either shower discharge or straight discharge can be selected, and high convenience can be given regarding the use of raw water.
If the inflow path to the flow path switching valve is changed so that the shutoff valve 16 is the purified water side and the shutoff valve 17 is the raw water side, the purified water side can be configured to be switchable between shower discharge and straight discharge.

[Function and effect]
In the fifth embodiment configured as described above, the push button 13 incorporated in the head 12 is operated to purify the push button 13 protruding from the head 12 (shallow push amount). In a state where the mixed water flows out from the purified water discharge port 12b and the push button 13 enters the head 12 and the amount of protrusion is small (deep push amount), the raw water flows out from the shower discharge port 12a.

  First, when the push button 13 has a shallow push amount, the raw water side shut-off valve 16 is closed, the purified water shut-off valve 17 is open, and the purified mixed water flows out, the push button 13 is pushed deep. The shut-off valve 16 is opened, the shut-off valve 17 is closed, and the raw water is switched to discharge. When the push button 13 is pushed again from this state and the push button 13 is changed to a shallow push amount, the shutoff valve 16 is closed and the shutoff valve 17 is opened to switch to discharge of purified water.

  At the time of discharging the purified water, the purified mixed water passes through the valve seat 17a of the shutoff valve 17 and flows out to the valve downstream side flow path 520 formed by the purified water conduit 565, and the water guide pipe 562 through the collecting passage 25. Flows out into the purified water flow path 519 formed by the water, passes through the purified water flow path 519, and is discharged from the purified water discharge port 12b.

  In the fifth embodiment, since the purified water discharge port 12b forms a straight discharge port and the raw water discharge port 12b forms a shower discharge port, it is easy to distinguish between purified water discharge and raw water discharge. In the clean water discharge, the discharge can be performed without switching the discharge and the operability is improved, so that the discrimination, visibility and operability are improved.

  Further, the raw water shut-off valve 16 and the purified water shut-off valve 17 of the flow path switching valve are alternately switched shut-off valves that alternately shut off the flow path by the same push button 13, and the raw water / purified water discharge Since the push-in position of the push button 13 is different, the push button 13 protruding from the head 12 can be used without mixing the clean water and raw water, and the operability can be further improved. .

  Moreover, since the shut-off valve 16 for raw water and the shut-off valve 17 for purified water are spherical valve bodies 16b and 17b, respectively, the water pressure applied to the spherical valve bodies 16b and 17b when the valves are closed is as follows: Together with the urging force of the coil springs 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, and can be reliably sealed.
