  A water discharge device incorporating a constant flow valve as described in Patent Document 1 is easy to use because the water discharge flow rate is adjusted to an appropriate value when installed in an area where the water supply pressure is high. However, when such a water discharge device is installed in an area where the supply water pressure is low, it is not necessary to incorporate a constant flow valve, and the water discharge flow rate is further increased due to pressure loss due to the insertion of the constant flow valve. Since it decreases, there is a problem in that the use of a constant flow valve deteriorates usability. Furthermore, when an automatic faucet with a built-in generator is installed in an area where the supply water pressure is low, as in the water discharge device described in Patent Document 1, sufficient power generation cannot be performed due to the pressure loss of the constant flow valve, and automatic The problem that the function as a water tap will be impaired occurs.

Therefore, it is difficult to remove. That is, in order to remove the constant flow valve, there is a problem in that it is necessary to disassemble the water passage in which watertightness is ensured, and it takes time to disassemble and assemble. Furthermore, when the water passage of the water discharge device assembled in the factory is disassembled at the construction site of the water discharge device, there is a problem that foreign matters are mixed into the water passage or cause water leakage due to poor assembly.

Are integrally formed. The constant flow valve outer portion 60 has a step-shaped constant flow valve third contact surface 70 formed on the outer periphery of the cylinder.
The constant flow valve inner portion 61 is disposed inside the constant flow valve outer portion 60. The constant flow valve internal water passage 64 is formed between the constant flow valve outer portion 60 and the constant flow valve inner portion 61. The constant flow valve internal water passage 64 adjusts the water flow through the water passage to a substantially constant flow regardless of the water pressure.

Next, the structure of the constant flow valve unit 14 according to the first embodiment of the present invention will be described with reference to FIGS.
The constant flow valve unit 14 includes a switching mechanism 36 and a constant flow valve 38.
The switching mechanism 36 includes a first water passage forming member 40, a second water passage forming member 42, and a water passage fixing mechanism 44.
As shown in FIG. 7, the first water passage forming member 40 is watertightly connected to the generator-side pipe 24 to form a first water passage 45 that is a part of the water passage 25. The first water passage forming member 40 has a convex cylindrical shape, and the protruding portion of the cylinder is formed to have a smaller diameter than the generator-side pipe 24 and is formed so as to substantially match the diameter of the constant flow valve 38. And has a first water passage abutment surface 48 at the tip of the convex cylinder. The first water passage abutment surface 48 abuts on the constant flow valve first abutment surface 46 of the constant flow valve 38, and the constant flow valve internal water passage 49 and the first water passage formation member inside the constant flow valve 38. The first water passage 45 inside 40 can be formed as one continuous water passage. Further, the end portion of the first water passage forming member 40 is slidably received in the second water passage forming member 42 in a watertight manner.

  The second water passage forming member 42 forms a second water passage 50 between the first water passage forming member 40 and the solenoid valve side pipe 22. The downstream end of the second water passage forming member 42 receives the first water passage forming member 40 so as to be slidable in a watertight manner. The second water passage forming member 42 is a substantially cylindrical member, and has an inner diameter that substantially matches the outer diameter of the first water passage forming member 40 so as to make watertight contact with the outside of the first water passage forming member 40. doing. The diameter of the water passage is changed so that the 2nd water passage formation member 42 can connect between the 1st water passage formation member 40 and the solenoid valve side piping 22. As shown in FIG. The second water passage forming member 42 is configured to accommodate and hold the constant flow valve 38 inside the second water passage 50 of the second water passage forming member 42. Furthermore, since the second water passage 50 in which the constant flow valve 38 is disposed is formed slightly larger than the constant flow valve 38, a gap is formed around the constant flow valve 38, and this gap will be described later. The three water passages 72 can be used for water passages.

FIG. 4 is a diagram illustrating the third water passage abutment surface 68 (FIG. 7) of the second water passage forming member 42 according to the first embodiment of the present invention when viewed from the upstream side.
As shown in FIG. 4, the second water passage forming member 42 is a second water passage forming member 42 while leaving a gap around the constant flow valve 38 (the constant flow valve is omitted in the figure for explanation). The second water passage 50 has a diameter slightly larger than that of the constant flow valve 38 so that it can be accommodated in the inside.
The second water passage formation member 42 includes four third water passage contact surfaces 68 that protrude in the cylindrical inner direction. The four third water passage contact surfaces 68 are formed so as to contact the constant flow valve third contact surface 70 of the constant flow valve 38. Since the portions other than the third water passage abutment surface 68 do not protrude, when the third water passage abutment surface 68 is in contact with the constant flow valve 38, the second water passage formation member 42 is in the non-contact portion. And a constant flow valve 38 are formed so that a gap (a part of a third water passage 72 described later) can be formed.

The water passage fixing mechanism 44 includes a water passage fixing pin 51 and a pin insertion portion 52.

The engaging portion 53 has a shape that can be inserted and fixed so as to be sandwiched along the cylindrical outer periphery of the second water passage forming member 42. In addition, the C-shape is opened downward. It may be a shape that is oriented or a shape in which a part of the lower part of the ring shape is cut out and opened downward. The engaging portion 53 is formed by extending the engaging portion 53 to about ± 120 degrees with respect to the handle portion 54 as viewed from the central axis of the second water passage forming member 42, and is sandwiched between the second water passage forming member. It is easy to maintain the engagement. The engaging portion 53 has an edge portion 55 whose chamfered edges are adjacent to the direction of insertion so as to facilitate insertion during insertion. The engaging part 53 has a thickness of about several millimeters, and the dimensions such as the thickness of the engaging part 53 can be designed according to the distance that the second water passage forming member 42 wants to slide. .
The handle 54 is formed with a thick top so that the user can easily operate it by hand. However, as a modification, the handle 54 may have a protruding shape or the like.
The engaging portion 53 and the handle portion 54 can be made of a material having elasticity so that it can be inserted so as to be sandwiched.

When the water passage fixing pin 51 is inserted from the outside of the water passage, the pin insertion portion 52 sets the relative position of the first water passage forming member 40 and the second water passage forming member 42 to the first position or the second position. Can be fixed in position. The pin insertion portion 52 includes a first position insertion portion 56 and a second position insertion portion 58 that can insert the water passage fixing pin 51 along the outer circumference of the cylinder of the second water passage formation member 42.
The first position insertion portion 56 has a concave shape formed along the outer periphery of the second water passage forming member 42 into which the water passage fixing pins 51 are inserted. When the water passage fixing pin 51 is inserted into the first position insertion portion 56, the water passage fixing pin 51 engages with the first position insertion portion 56 and the solenoid valve side pipe 22, and the second water passage formation member 42. Is supposed to be fixed.
The second position insertion portion 58 is substantially the same in shape as the first position insertion portion 56 and is different in that the position is close to the generator side pipe 24. When the water passage fixing pin 51 is inserted into the second position insertion portion 58, the water passage fixing pin 51 engages with the second position insertion portion 58, the generator side pipe 24, and the like, so that the second water passage formation member is engaged. 42 is fixed.

Next, the effect | action of the water discharging apparatus 1 by 1st Embodiment of this invention is demonstrated.
First, when the user holds a finger over the human sensor 8 provided at the tip of the water discharge device main body 2, the human sensor 8 detects this and sends a signal to the control unit 18. When the human sensor 8 detects a finger, the control unit 18 sends a signal to the electromagnetic valve 12 to switch the electromagnetic valve 12 to an open state. When the solenoid valve 12 is opened, hot water and water supplied via the hot water supply pipe 20a and the water supply pipe 20b are supplied to the temperature control valve 10, respectively. The supplied hot water and water are mixed inside the temperature control valve 10, flow through the constant flow valve portion 14 as shown by arrows in FIGS. 7 and 8, and reach the generator 16. Hot water that has passed through the generator 16 is discharged from the spout 6.

  That is, the supplied hot water and water are adjusted to the temperature set by the temperature adjusting knob 4 by the temperature adjusting valve 10 and flow out. The hot water flowing out of the temperature control valve 10 passes through the solenoid valve 12 in the valve open state. The hot water that has passed through the electromagnetic valve 12 flows through the constant flow valve section 14 and reaches the generator 16.

  Next, referring to FIG. 7 and FIG. 8, switching of the water passage by the switching mechanism 36 will be described. FIG. 7 shows a state where the second water passage forming member 42 into which the supplied hot water flows into the generator 16 through the constant flow valve 38 is in the first position. On the other hand, FIG. 8 shows a state where the second water passage forming member 42 in which at least part of the supplied hot water flows into the generator 16 without passing through the constant flow valve 38 is in the second position.

  As shown in FIG. 7, at the first position of the second water passage forming member 42, the water passage fixing pin 51 is inserted into the first position insertion portion 56 of the second water passage forming member 42, and the second water passage The forming member 42 is moved to the downstream side (left side in FIG. 7). In this first position, the constant flow valve 38 is sandwiched and supported between the first water passage forming member 40 and the second water passage forming member 42. When the second water passage forming member 42 is fixed at the first position, the first water passage contact surface 48 of the first water passage forming member 40 and the constant flow valve first contact surface 46 of the constant flow valve 38 are Abut. Accordingly, the hot water supplied from the electromagnetic valve 12 passes through the constant flow valve internal water passage 49 as shown by the arrow in FIG. The hot water passing through the constant flow valve 38 is maintained at a constant flow rate by the function of the constant flow valve 38. The hot water that has passed through the constant flow valve 38 flows through the first water passage 45 inside the first water passage forming member 40 and is guided to the generator 16. Thus, in the first position, almost all of the supplied hot water passes through the constant flow valve 38, and hot water with an appropriate flow rate flows into the generator 16.

On the other hand, when the water discharge device 1 is disposed in an area where the supply water pressure is low, if the supplied hot water flows into the generator 16 through the constant flow valve 38, sufficient power generation is caused by the pressure loss caused by the constant flow valve 38. Can not be. In such a case, the switching mechanism 36 switches the constant flow valve 38 to the second position so that a part of the supplied hot water flows into the generator 16 without passing through the constant flow valve 38. To do.
In order to switch the constant flow valve 38 from the first position shown in FIG. 7 to the second position shown in FIG. 8, the user first removes the cover 9 and exposes the water passage in the water discharger main body 2. The fixing pin 51 is pulled out from the first position insertion portion 56. Next, the water passage fixing pin 51 is inserted into the second position insertion portion 58 of the second water passage forming member 42 from the outside of the water passage. When the water passage fixing pin 51 is pushed into the second position insertion portion 58, the second water passage forming member 42 is moved upstream (rightward in FIG. 7) by the water passage fixing pin 51.
When the water channel fixing pin 51 is pushed to the end, the second water channel forming member 42 is slid to the second position shown in FIG. 8 while maintaining the water tightness, and the second water channel forming member 42 is the second water channel forming member 42. Fixed in position. In the second position, the relative position of the second water passage forming member 42 with respect to the first water passage forming member 40 is moved in a direction away from the first water passage forming member 40 by about 1.5 mm to 2 mm from the first position. It is the position.

  As shown in FIG. 8, when the second water passage forming member 42 is moved to the second position, the third water passage abutting surface 68 of the second water passage forming member 42 and the constant flow valve 38 of the constant flow valve 38 are arranged. Since the three contact surfaces 70 are in contact, the constant flow valve 38 is moved together with the second water passage forming member 42. Due to the movement of the constant flow valve 38, the first constant flow valve contact surface 46 and the first water passage contact surface 48 are separated from each other, and the third constant flow valve 38 is newly bypassed around the constant flow valve 38. A water passage 72 is formed. The third water passage 72 is fixed to the second water passage forming member 42 when the third water passage abutment surface 68 is in contact with the constant flow valve third abutment surface 70 around the constant flow valve outer portion 60. A water passage that allows water to flow along the outer periphery of the constant flow valve 38 between the constant flow valve first abutment surface 46 and the first water passage abutment surface 48. is there. The third water passage 72 is formed in an annular shape around the constant flow valve 38, and the constant flow valve internal water passage 64 and the third water passage 72 form a concentric double ring passage.

It is switched by doing. The water passage fixing mechanism 44 fixes the relative position of the first water passage forming member 40 and the second water passage forming member 42 from the outside of the water passage to the first position or the second position. Thus, the first position and the second position of the constant flow valve 38 can be obtained without disassembling the second water passage 50 only by relatively moving the first water passage forming member 40 and the second water passage forming member 42. Can be switched. Furthermore, compared with the structure etc. which provide the water flow path which does not pass through the constant flow valve 38 separately, the number of parts does not increase and the water discharging apparatus 1 can be comprised by simple structure, without enlarging.

In the present embodiment, the constant flow valve 38 is arranged in the second water passage 50 so that the water discharge flow rate from the water discharge port 6 is adjusted to an appropriate value and an appropriate water supply pressure acts on the generator 16. Yes. However, when the water discharge device 1 is installed in an environment where the feed water pressure is low, since there is a pressure loss due to passing through the constant flow valve 38, the feed water pressure flowing into the generator 16 is reduced and sufficient power generation is performed. It becomes difficult. In such a case, the switching mechanism 36 is switched to the second position, the hot water is diverted to the third water passage 72, the pressure loss due to the constant flow valve 38 is reduced, and the generator 16 can generate sufficient power. To.
