Description

  The present invention relates to a water faucet and a water faucet device provided with the water faucet.

When the faucet device is installed in a cold region, the water in the faucet body or the water pipe may freeze at night in winter. If the water in the faucet body or water pipe freezes, problems such as damage due to excessive force due to expansion, or the inability to discharge water until the ice melts in the morning will occur. Resulting in.
In order to prevent this, it is necessary to drain the water in the faucet body or the water pipe at the time when freezing is expected. In cold regions, a water drain plug is provided in the building pipe, and the water can be drained from the peripheral equipment connected to the building pipe by operating the plug. However, when the faucet device is in a water stop state, air cannot be taken in from the outside, and the water on the upstream side of the water stop valve cannot be sufficiently drained. In order to prevent this, when draining water, operate all faucet devices to pass through water or operate a drain cock provided separately to open the interior of the faucet device to the atmosphere. There was a need to unplug. In the case of a hot and cold water mixing faucet device, since it is necessary to open the drain cocks at a plurality of locations, there is a problem of troublesome draining work.

  In order to solve the above problems, a faucet having a connection part connected to a water pipe, a plug function part for switching between water discharge and water stop, and an intake valve provided between the connection part and the plug function part An apparatus has been proposed (Patent Document 1).

When the rear end 109a) of the shaft portion 109 and the packing 118 are in contact with and in close contact with the seat surface 102e formed on the supply leg main body 102, the seat surface 102e serves as a valve seat and the internal flow of the supply leg main body 102 is increased. The internal flow path of the path supply leg main body 102 is in a stopped state.

  On the other hand, as shown in FIG. 3, when the water stop valve body 111 rear side support projection 111b and packing 118 of the water stop plug member 106 are not in contact with the seat surface 102e formed on the supply leg body 102, The internal flow path of the leg main body 102 is in a state where water is passed through.

Further, a front support protrusion 111 a for engaging the pressure regulating valve urging spring 114 is provided at an intermediate portion of the water stop cock member 106. Further, a central bore 109 d for slidably receiving the intake valve body 110 is formed so as to penetrate the rotation shaft portion 109 of the water stop valve member 106 along the center axis of the water stop valve member 106. Yes.

  The pressure regulating valve body 108 is a thin stepped cylindrical member, and is slidably disposed with respect to the water stop valve member 106 so as to surround the water stop valve member 106. A pressure regulating valve biasing spring 114 is disposed between the water stop valve member 106 and the pressure regulating valve body 108. The pressure regulating valve urging spring 114 is a coil spring disposed so as to surround the water stop valve member 106, and a pressure regulating valve body 108 is disposed so as to surround the periphery thereof.

  Further, the pressure regulating valve body 108 is disposed so as to surround and contact the annular packing 118 attached to the water stop valve member 106, so that hot water (water) does not flow into the pressure regulating valve body 108. It has become. Further, the pressure regulating valve urging spring 114 is disposed so that one end thereof is in contact with the flange 111 a of the water stop valve member 106 and the other end is in contact with the stepped portion of the pressure regulating valve body 108. For this reason, the pressure regulating valve body 108 is urged by the pressure regulating valve urging spring 114 in a direction away from the seat surface 102e.

  The valve body presser 112 is an annular cap-shaped member, and is configured to fix the water stop valve member 106 to the valve body receiving recess 102 c of the supply leg main body 102. A male threaded portion 112 a is formed on the outer periphery of the distal end of the valve body retainer 112, and the male threaded portion 112 a is screwed into a female threaded portion provided on the supply leg main body 102, whereby the valve body retainer 112 is attached to the supply leg main body 102. Fixed. On the other hand, a stepped circular bore 112b is formed on the central axis of the valve body presser 112, and the pressure regulating valve body 108 is received therein. The pressure regulating valve body 108 is urged toward the valve body presser 112 by a pressure regulating valve urging spring 114, and the urging force presses the stepped portion of the pressure regulating valve body 108 against the stepped circular bore 112b. It has been.

  The intake valve body 110 is a stepped round bar-like valve body, and is disposed so as to be slidable in the axial direction within the central bore 109 d of the water stop valve member 106. In addition, an inclined tapered portion is provided at an intermediate portion of the intake valve body 110, and an intake valve body packing 110a is attached to the tapered portion.

When the intake valve body packing 110a contacts the inclined inner wall surface, the central bore 109d is closed and closed. To be spoken.

  An intake valve biasing spring 116 is disposed inside the center bore 109d, and the intake valve biasing spring 116 biases the tip of the intake valve body 110. The intake valve urging spring 116 is a weak spring and urges the intake valve body 110 so that the intake valve body packing 110a of the intake valve body 110 is separated from the inner wall surface of the central bore 109d. That is, the intake valve body 110 is biased toward the valve opening side. Since the intake valve biasing spring 116 is a weak spring, the intake valve body packing 110a is caused by the pressure acting on the intake valve body 110 in a state where a normal water supply pressure is applied in the water passage of the supply leg main body 102. The intake valve body 110 is closed by contacting the inner wall surface of the central bore 109d.

Next, the action of the water supply leg 6 provided in the hot and cold water mixing faucet device of this embodiment will be described. As described above, in the present embodiment, the hot water supply leg (not shown) has the same configuration as the water supply leg 6 and operates in the same manner as the water supply leg 6 except that water flows inside. To do.
First, when the spout water switching handle is operated to discharge water, hot water and water flow into the water supply leg 6 and the hot water supply leg (not shown), respectively. The hot water that has flowed in from the supply pipe connecting portion 102a flows in the supply leg main body 102 along the path indicated by the arrow in FIG. 2, and flows out from the main body connecting portion 102b. Hot water and water that have passed through the water supply leg 6 and the hot water supply leg (not shown) respectively flow into the hot water mixing chamber 21. The operation of the hot and cold water mixing faucet after hot water and water have flowed into the hot water and water mixing chamber 21 will be described in detail later.

  Further, when the supply pressure from the supply pipe connecting portion 102a is high, the hot water flowing into the water supply leg 6 flows from the gap between the outer peripheral surface of the pressure regulating valve body 108 and the inner wall surface of the stepped circular bore 112b. The pressure in the annular gap 120 between the step portion of the pressure regulating valve body 108 and the step portion of the stepped circular bore 112b increases. As the pressure in the annular gap 120 increases, the pressure regulating valve body 108 moves in the direction of the seat surface 102e against the biasing force of the pressure regulating valve biasing spring 114 (the annular gap 120 widens). When the pressure regulating valve body 108 is moved toward the seat surface 102e, the gap between the tip of the pressure regulating valve body 108 (the seat surface 102e side) and the seat surface 102e becomes narrow, and the flow path of the flow through this gap Resistance increases. Thereby, the pressure of the hot water flowing out from the supply leg main body 102 is adjusted to a predetermined value. In addition, the pressure regulation valve with which the hot water supply leg (not shown) was equipped acts similarly.

  Further, when the supply of hot water and water to the faucet body 2 is stopped for maintenance or the like, the water stop valve member 106 is used to stop water. That is, by inserting a screwdriver or the like into the notch 109c of the water stop valve member 106 and rotating it, the male screw portion 107 is screwed into the female screw portion 102d, and the water stop valve member 106 is moved toward the seat surface 102e. When the water stop valve member 106 is moved until the annular packing 118 contacts the seat surface 102e, the water stop valve is closed and the flow path of the water supply leg 6 is closed. In addition, the water stop valve with which the hot water supply leg (not shown) was equipped acts similarly.

Next, the structure of the drainage part 18 is demonstrated with reference to FIG. FIG. 4 is a cross-sectional view of the hot and cold water mixing device 1.
As shown in FIG. 4, the drainage section 18 includes a drainage valve body 18a, a drainage valve body 18b slidably disposed in the drainage valve body 18a, and a drainage valve body that urges the drainage valve body 18b.

Further, the drainage portion 18 is provided in parallel with the currant 12 so as to communicate with the currant 12.

The drain valve main body 18a is a substantially cylindrical member, and a drain valve port forming member 18d is disposed on the tip side thereof.
The drain valve body 18b has a valve portion seated on the valve port of the drain valve port forming member 18d, and a valve shaft portion extending from the valve portion to the back side, and the valve shaft portion is axially moved by the drain valve body 18a. It is slidably supported on.
The drain valve body urging spring 18c is disposed around the valve shaft portion of the drain valve body 18b, and urges the drain valve body 18b to the valve opening side (upward in FIG. 4) with a weak urging force.

  With such a configuration, in the state where water discharge from the currant 12 is performed, the pressure in the water passage from the switching valve 16 to the currant 12 increases, so the drain valve body 18b is provided with a drain valve body. It is pushed down against the urging force of the urging spring 18c, and the valve port of the drain valve port forming member 18d is closed. Further, in the state where the water discharge from the currant 12 is stopped, the pressure in the water passage is reduced, so that the valve port of the drain valve port forming member 18d is opened by the biasing force of the drain valve body biasing spring 18c. It will be in a state where drainage is possible.

Next, with reference to FIG. 4 thru | or FIG. 6, the structure of the hot / cold water mixing temperature control apparatus and the switching valve incorporated in the faucet body will be described.
FIG. 5 is a perspective view of the hot and cold water mixing temperature controller and the switching valve. FIG. 6 is an exploded perspective view of the hot and cold water mixing temperature controller and the switching valve.

Further, the hot and cold water mixing temperature adjusting device 20 is a main valve body 30 that is movably disposed inside the first main body member 22, and a bias that is a biasing means that biases the main valve body 30 in the right direction in FIG. A spring 32 and a temperature sensitive spring 34 which is a temperature sensitive urging means for urging the main valve body 30 in the left direction in FIG. 4 opposite to the bias spring 32 are provided. In the present embodiment, a coil spring made of a shape memory alloy is used as the temperature sensitive spring 34.

  As shown in FIGS. 4 and 6, the first main body member 22 has a substantially cylindrical shape and is coupled to the second main body member 24 located on the right side in FIG. 4. Further, the first main body member 22 is provided with a hot water inlet 22a for flowing hot water and a water inlet 22b for flowing water in the circumferential direction. Further, the left end surface of the hot water inlet 22 a in FIG. 4 is formed as a hot water side seat portion 22 c that contacts the main valve body 30. Therefore, the hot water side sheet | seat part 22c forms a part of hot water inflow port 22a.

  The second main body member 24 has a substantially cylindrical shape, and is coupled to the first main body member 22 by receiving an end portion of the second main body member 24 at an end portion of the first main body member 22. The space inside the first main body member 22 and the second main body member 24 functions as a hot water mixing chamber 21 for mixing hot water and water flowing in from the hot water inlet 22a and the water inlet 22b.

  The sliding sleeve 25 has a substantially cylindrical shape, and is slidably disposed inside the second body member 24. Further, the distal end portion of the sliding sleeve 25 is formed as a water side seat portion 25 a that contacts the main valve body 30. For this reason, by sliding the sliding sleeve 25 relative to the second main body member 24, the distance between the hot water side sheet portion 22c and the water side sheet portion 25a can be changed. Further, a discharge port 25 b through which hot water mixed in the hot water mixing chamber 21 flows out is formed at the end of the sliding sleeve 25 opposite to the first main body member 22. The supplied water flows between the one end portion of the main valve body 30 and the water side seat portion 25a and flows into the hot water mixing chamber 21, so that the water side seat portion 25a forms a part of the water inlet. ing.

  The cam member 27 is an annular member and is rotatably disposed inside the second main body member 24. Further, the right end of the cam member 27 in FIG. 4 protrudes from the right end of the second main body member 24. A cam 27a is formed on the end surface of the cam member 27 on the sliding sleeve 25 side so as to change the height in the axial direction. On the other hand, a cam portion 25c is also formed on the end surface of the sliding sleeve 25 on the cam member 27 side, and the cam portion 25c slides with respect to the cam 27a. With this configuration, when the cam member 27 is rotated, the sliding sleeve 25 is moved in the axial direction. As will be described later, in the water stop state, the sliding sleeve 25 is slid to a position where both the hot water side seat portion 22c and the water side seat portion 25a simultaneously contact the main valve body 30, and the hot water inlet 22a and The water inlet 22b is closed. On the other hand, in the water discharge state, the slide sleeve 25 is slid so that the distance between the hot water side sheet portion 22c and the water side sheet portion 25a is longer than that in the water stop state.

  Thus, in the hot and cold water mixing faucet device 1 of the present embodiment, water discharge and water stop are switched by sliding of the sliding sleeve 25, and water discharge from the currant 12 and water discharge from the shower head 14 are performed by the switching valve 16. Can be switched. Accordingly, the switching valve 16 and the sliding sleeve 25 function as a discharge water switching mechanism. Further, the hot water inlet 22a and the water inlet 22b are closed by the action of the sliding sleeve 25 and the cam member 27 sliding relative thereto, so that the sliding sleeve 25 and the cam member 27 function as an inlet valve drive mechanism.

The rectifying member 39 is a cylindrical member having one end narrowly closed, and is disposed so as to be received in the annular portion of the legged annular member 38. The spring retainer fitting 36 is a donut plate-like fitting with a raised central portion, and is connected to the rectifying member 39 by a U-shaped fitting 44. The bias spring 32 is sandwiched between the annular portion of the legged annular member 38 and the spring retainer 36 and is disposed inside the first main body member 22 in a compressed state. With this configuration, the bias spring 32 urges the main valve body 30 in the right direction in FIG. 4 when the sliding member 28 abuts against the spring retainer 36.

As shown in FIG. 4, a mixing blade member 40 and a temperature sensitive spring 34 are arranged on the right side of the main valve body 30. The mixing blade member 40 is a substantially disk-shaped member and is slidably disposed inside the sliding sleeve 25. Further, the left end portion of the mixing blade member 40 in FIG. 4 is disposed so as to contact the main valve body 30, and the hot water and water flowing into the hot water mixing chamber 21 are mixed in this end portion so that the temperature is uniform. Radial blades 40a (FIG. 6) are provided.
The left end of the temperature-sensitive spring 34 in FIG. 4 is in contact with the mixing blade member 40, and the right end is disposed in contact with the end of the inner wall surface of the sliding sleeve 25. With this configuration, the temperature-sensitive spring 34 biases the main valve body 30 in the left direction in FIG. 4 via the mixing blade member 40.

  On the other hand, cylindrical filters 52 and 54 are disposed outside the first main body member 22 so as to cover the hot water inlet 22a and the water inlet 22b, respectively. Inflow into the mixing temperature controller 20 is prevented.

Next, the configuration of the switching valve 16 will be described with reference to FIGS.
The switching valve 16 includes a switching valve main body 60, a packing pressing member 62 disposed inside the switching valve main body 60, a rotating cylinder 64 disposed rotatably inside the packing pressing member 62, and a switching for rotating the rotating cylinder 64. And a shaft member 66.

  The switching valve main body 60 is a substantially cylindrical member, and on its side surface, a currant outlet 60a that is a first valve port for flowing hot water mixed in the hot water mixing chamber 21 to the curran 12 side, and a shower head side A shower outlet 60b is provided as a second valve port that flows out into the outlet. As shown in FIG. 6, the currant outlet 60a and the shower outlet 60b are formed at positions shifted in the axial direction of the switching valve main body 60 and at positions shifted by a central angle of about 90 ° in the circumferential direction. Has been.

  The packing pressing member 62 is a thin cylindrical member, and is provided with openings at positions aligned with the currant outlet 60a and the shower outlet 60b, respectively. Packings 62a and 62b are fitted in these openings. Thereby, packing 62a, 62b is hold | maintained so that the circumference | surroundings of the Karan outflow port 60a and the shower outflow port 60b may each be surrounded.

  The rotating cylinder 64 is a cylindrical member, and is rotatably fitted inside the packing pressing member 62. A notch 64c is provided at the end of the rotating cylinder 64 on the hot water / water mixing temperature controller 20 side (left side in FIG. 4). The notch 64c is formed to receive a protrusion 27b (FIG. 6) provided on the cam member 27 protruding from the end of the second main body member 24. With this configuration, the cam member 27 and the rotary cylinder 64 are engaged, and the cam member 27 is rotated with the rotation of the rotary cylinder 64.

  Further, two sets of outflow openings 64 a and 64 b (only 64 b is shown in FIG. 6) are formed on the side surface of the rotating cylinder 64 at positions shifted in the axial direction of the rotating cylinder 64. Furthermore, each outflow opening 64a, 64b is formed at a position shifted by a predetermined angle in the circumferential direction. By rotating inside the packing holding member 62, the rotary cylinder 64 has a position where only the Karan outlet 60a and the outflow opening 64a communicate with each other, a position where only the shower outlet 60b and the outflow opening 64b communicate with each other, and a Karan outlet. The position where 60a and the shower outlet 60b communicate with the outflow openings 64a and 64b can be taken. In the switching valve 16 of the present embodiment, both the currant outlet 60a and the shower outlet 60b are not in communication with the outflow openings 64a and 64b. That is, in the switching valve 16 of the present embodiment, at least one of the currant outlet 60a and the shower outlet 60b is always in communication with the outlet openings 64a and 64b.

  The switching shaft member 66 is an elongated shaft member, and one end is attached to the end of the rotating cylinder 64 and the other end is attached to the spouting water switching handle 10 (FIG. 4). Thereby, when the spouting water switching handle 10 is rotated, the switching shaft member 66, the rotating cylinder 64, and the cam member 27 are rotated together.

Next, with reference to FIG. 4, the operation of the hot and cold water mixing temperature adjusting device 20 in the hot and cold water mixing faucet device 1 according to the first embodiment of the present invention will be described.
First, the user of the hot and cold water mixing apparatus 1 sets the hot water temperature adjusting dial 8 to a desired temperature. Here, when the hot water temperature adjusting dial 8 is set to the minimum temperature, the sliding member 28 is positioned at the left end in FIG. In this state, as shown in FIG. 4, since the sliding member 28 is separated from the spring retainer 36, the biasing force by the bias spring 32 does not act, and the left end of the main valve body 30 in FIG. The hot spring 34 is brought into contact with the hot water side sheet portion 22 c by the urging force of the thermal spring 34. That is, only the water can flow into the hot water mixing chamber 21.

  Next, when the user operates the hot water temperature adjusting dial 8 to rotate the feed screw 26 in order to increase the set temperature, the sliding member 28 is moved rightward in FIG. Is in contact with the spring retainer 36. As a result, the biasing force by the bias spring 32 also acts on the main valve body 30, and the main valve body 30 is moved to a position where the biasing force of the bias spring 32 and the biasing force of the temperature-sensitive spring 34 are balanced.

  When the main valve body 30 is moved, the hot water introduced from the hot water supply leg 4 flows into the hot water inlet 22 a via the filter 52, and the water introduced from the water supply leg 6 passes through the filter 54. Then flows into the water inlet 22b. Hot water flowing from the hot water inlet 22a passes between the main valve body 30 and the hot water side seat portion 22c and flows into the hot water mixing chamber 21, and water flowing from the water inlet 22b flows into the main valve body 30 and the water side seat. It flows into the hot water mixing chamber 21 through the portion 25a.

  The hot water that has flowed into the hot water mixing chamber 21 flows in the right direction in FIG. Further, the water flowing into the hot water mixing chamber 21 is mixed with hot water flowing through the main valve body 30 and flows out from the discharge port 25 b mainly through the inside of the temperature sensitive spring 34. At this time, mixing of hot water and water is promoted by the blade 40 a of the mixing blade member 40, and the mixture is mixed at a substantially uniform temperature and flows through the temperature-sensitive spring 34. Hot water that has flowed out from the discharge port 25 b passes through the switching valve 16 and is discharged from the currant 12 or the shower head 14.

  When the temperature of the hot water flowing inside the temperature-sensitive spring 34 is higher than the set temperature, the temperature-sensitive spring 34 acts to extend, so that the urging force by the temperature-sensitive spring 34 increases. Thereby, the position where the urging force by the temperature sensitive spring 34 and the urging force by the bias spring 32 are balanced is moved to the left in FIG. 4, and the main valve body 30 is moved to the left. As a result, the distance between the left end portion of the main valve body 30 and the hot water side seat portion 22c is shortened, and the distance between the right end portion of the main valve body 30 and the water side seat portion 24b is increased. The ratio of the water flowing into the water increases, and the temperature of the discharged hot water decreases. On the contrary, when the temperature of the hot water flowing inside the temperature-sensitive spring 34 is lower than the set temperature, the urging force by the temperature-sensitive spring 34 decreases, and the main valve body 30 is moved rightward in FIG. The temperature of the discharged hot water rises. By these actions, the temperature of hot water discharged from the currant 12 or the shower head 14 is adjusted to the set temperature.

Next, the operation of the switching valve 16 will be described with reference to FIG.
FIG. 7 is a graph in which the rotation angle of the spouting water switching handle is shown on the horizontal axis, and the water passage area (valve opening) of the switching valve and the hot and cold water mixing temperature adjusting device is shown on the vertical axis. In FIG. 7, the water passage area of the switching valve 16 is indicated by a broken line and a one-dot chain line, and the water passage area of the switching valve 16 is the water passage area (one-dot chain line) of the Karan outlet 60a and the passage of the shower outlet 60b. Consists of channel area (broken line). Moreover, in FIG. 7, the water passage area of the hot and cold water mixing temperature controller 20 is indicated by a solid line, and the water passage area of the hot water and water temperature controller 20 is the sum of the water passage areas of the hot water inlet 22a and the water inlet 22b. I mean. Here, when the distance from the hot water side sheet | seat part 22c to the water side sheet | seat part 25a (FIG. 4) is equal to the axial direction length of the main valve body 30 (FIG. 4), the hot water inlet 22a and the water inlet 22b are It is closed and the water passage area of the hot and cold water mixing temperature controller 20 becomes zero. The sliding sleeve 25 is moved to the right side in FIG. 4, and the water passage of the hot and cold water mixing temperature adjusting device 20 becomes longer as the distance from the hot water side seat portion 22 c to the water side seat portion 25 a becomes longer than the axial length of the main valve body 30. The area increases.

As shown in FIG. 7, when the angle of the spouting water switching handle 10 is 0 ° (center position), the cam portion 25 c of the sliding sleeve 25 and the convex portion of the cam 27 a (FIG. 6) of the cam member 27. The sliding sleeves 25 are moved to the leftmost side in FIG. In this state, since both ends of the main valve body 30 are in contact with the hot water side seat portion 22c and the water side seat portion 25a, respectively, the hot water inlet 22a and the water inlet 22b are closed. The sliding sleeve 25 is maintained at substantially the same position over the range of the rotation angle of the discharge water switching handle 10 about ± 5 ° centering on the state of the angle 0 °, and the main valve body 30 and the hot water side seat The part 22c and the water side sheet part 25a are maintained in a contact state. The slight movement of the sliding sleeve 25 in this angular range is absorbed by the elastic deformation of the packing formed at both ends of the main valve body 30, and the main valve body 30, the hot water side sheet portion 22c, and the water side seat portion. 25a is maintained in a contact state.
Thereby, the hot water inlet 22a and the water inlet 22b are maintained in the closed state.

  On the other hand, as shown in FIG. 7, the currant outlet 60a and the shower outlet 60b in the switching valve 16 span an angle range of about ± 5 ° centered on the rotation angle 0 ° of the spouting water switching handle 10. Both are kept open. However, as described above, in this angle range, the hot water inlet 22a and the water inlet 22b are in a closed state, so water discharge from the currant 12 and the shower head 14 is not performed, and the water is stopped.

  Further, when the discharge water switching handle 10 is rotated to the shower side by about + 5 ° or more, the currant outlet 60a is closed by the rotating cylinder 64 (one-dot chain line in FIG. 7), while the water passage area of the shower outlet 60b is closed. Increases (broken line in FIG. 7). The cam member 27 of the hot / cold water mixing temperature adjusting device 20 is rotated in conjunction with the rotation of the discharge water switching handle 10. Thereby, the convex part of the cam 27a comes into contact with the vicinity of the concave part of the cam part 25c of the sliding sleeve 25 (FIG. 6), and the sliding sleeve 25 is moved rightward in FIG. By moving the sliding sleeve 25, the water passage area of the hot and cold water mixing temperature controller 20 is secured. Thereby, the hot water and water flowing in from the hot water inlet 22a and the water inlet 22b are mixed in the hot water mixing chamber 21, flowed into the switching valve 16, and discharged from the shower head 14 through the shower outlet 60b.

  Further, when the spout water switching handle 10 is turned to the curran side by about −5 ° or more, the shower outlet 60b is closed by the rotating cylinder 64 (broken line in FIG. 7), while the water passage area of the currant outlet 60a is closed. Increases (the chain line in FIG. 7). In conjunction with the rotation of the discharge water switching handle 10, the convex portion of the cam 27a comes into contact with the vicinity of the concave portion of the cam portion 25c of the sliding sleeve 25. Moved in the direction. Thereby, the hot water and water mixed in the hot water mixing chamber 21 flow into the switching valve 16 and are discharged from the currant 12 through the currant outlet 60a.

  Next, when the spouting water switching handle 10 is returned to the vicinity of the center position (rotation angle range of about ± 5 °), the hot water inlet 22a and the water inlet 22b are closed to enter a water stop state, while the currant outlet 60a. And the shower outlet 60b will be in the open state. In this state, the water spray hole of the shower head 14 and the water outlet of the currant 12 are in communication with each other via the switching valve 16 (and the hot water mixing chamber 21 connected thereto). Further, as shown in FIG. 4, since the currant 12 and the drainage part 18 are always in communication with each other, the drainage part 18 is also in communication with the water spray holes of the shower head 14 and the hot water mixing chamber 21. Moreover, in the water stop state, since the pressure in the water passage from the switching valve 16 to the drainage portion 18 is reduced, the drainage valve body 18b of the drainage portion 18 is moved to the valve open position.

  In such a water stop state, the hot water remaining in the hot water mixing chamber 21 is discharged from the currant 12 and / or the drainage part 18 via the currant outlet 60a. At the same time, outside air is sucked into the hot water / mixing chamber 21 through the water spray holes of the shower head 14 and the shower outlet 60b.

Next, with reference to FIG. 8, the water draining operation in the hot and cold water mixing faucet device according to the first embodiment of the present invention will be described.
FIG. 8 is a block diagram for explaining a water draining operation of the hot and cold water mixing faucet device 1 according to the present embodiment.
First, when draining water, the hot water and water mixing faucet device 1 is set to the water-stopping state, and the water faucets (not shown) provided on the upstream side of the hot water supply leg 4 and the water supply leg 6 are connected to the drain side. To operate. Thereby, the inside of piping upstream from the hot water inlet 22a and the water inlet 22b becomes a negative pressure. When the pressure in the upstream pipe becomes negative, the pressure acting on the intake valve body 110 decreases, and the intake valve body 110 is in the state shown in FIG. 2A due to the urging force of the intake valve urging spring 116. To the state shown in FIG. As a result, the intake valve body packing 110a is separated from the inner wall surface of the central bore 109d, and the intake valve is opened. Further, the intake valve provided on the hot water supply leg (not shown) is similarly opened. When the intake valve is opened, the outside air flows into the pipe through the path indicated by the arrow in FIG. 3, and the hot water and water staying upstream of the hot water inlet 22a and the water inlet 22b are retained. Discharged. Therefore, according to the hot and cold water mixing faucet device of the present embodiment, all the draining operations are completed simply by operating a draining plug (not shown) to the draining side.

  According to the stop cock 104 with the intake valve of the first embodiment of the present embodiment, the intake valve body 110 is provided compactly on the hot water supply leg and the water supply leg by providing the intake valve body 110 on the stop cock 104. be able to. In addition, according to the present embodiment, by providing the stop valve 104 with the intake valve body 110, the hot water / water mixed water having the water draining function is maintained while maintaining the same appearance as the hot water / water mixing faucet apparatus having no water draining function. A stopper device can be constructed. That is, a faucet device having a water draining function can be configured without greatly changing the overall design from the conventional faucet device. Further, according to the present embodiment, since the intake valve body 110 is integrated with the stop cock 104 and the pressure regulating valve 108, the stop cock of a general-purpose hot water supply leg (water supply leg) is connected to the intake valve. A hot and cold water mixing faucet device having a water draining function can be configured simply by exchanging with a unitized faucet.

  Further, according to the water stop cock 104 with an intake valve of the present invention, the intake valve body 110 is moved to the valve closing side by the water pressure in the water passage, and is moved to the valve opening side when the pressure in the water passage becomes negative. . Therefore, when draining the hot and cold water mixing faucet device 1 in the water-stopped state, a water faucet (not shown) provided in the flow path upstream of the hot water inlet 22a and the water inlet 22b is simply used. Only by operating to the drain side, outside air is introduced into the flow path from the intake valve body 110, and drainage of the upstream side of the hot water inlet 22a and the water inlet 22b is completed. On the other hand, on the downstream side of each inflow port, the hot water inflow port 22a and the water inflow port 22b are closed, and the hot water mixing chamber 21, the drainage unit 18, the currant 12 as the water discharge unit, and the shower head 14 in the water stop state. Therefore, the hot water remaining in the hot / cold water mixing chamber 21 is discharged from the drainage part 18 or the currant 12. As a result, it is not necessary to perform a special draining operation on the hot water / water faucet device 1, and draining can be performed very easily.

  Further, according to the water stop cock 104 with an intake valve of the present invention, the intake valve body 110 is provided with the intake spring 116 that urges the intake valve body 110 toward the valve opening side. When the water pressure decreases, the outside air can be surely sucked into the water passage.

  Further, according to the water stop cock 104 with the intake valve of the present invention, since the intake valve body 110 is provided with manual valve opening means for forcibly opening the intake valve, the intake valve is fixed and the intake valve is difficult to operate. Even in such a case, by operating the manual valve opening means, it is possible to reliably perform intake and drain water.

  Moreover, according to the hot water / water mixing faucet device 1 of the present invention, the water faucet function is provided without significantly changing the overall design from the conventional hot water / water mixing faucet device by providing the water stop cock 104 with the intake valve. It is possible to provide a hot and cold water mixing device.

  Further, the hot and cold water mixing faucet device 1 of the present embodiment includes a switching valve 16 provided on the downstream side of the hot water and mixing chamber 21 as part of the discharge water switching mechanism. And a shower outlet 60b for connecting the hot water / water mixing chamber 21 and the shower head 14 with each other, and only the Karan outlet 60a is opened at the time of water discharge from the Karan 12. At the time of water discharge from the head 14, only the shower outlet 60b is opened, and when switched to the water stop state, both the currant outlet 60a and the shower outlet 60b are opened. For this reason, with a simple structure, the hot water mixing chamber, the curan 12 as the first water discharger, and the shower head 14 as the second water discharger can be communicated with each other in the water stop state.

  Further, the hot and cold water mixing faucet device 1 of the present embodiment includes a cam member 27 and a sliding sleeve 25 which are inlet valve driving mechanisms as a part of the discharge water switching mechanism. The cam member 27 is interlocked with the switching valve 16 to slide the sliding sleeve 25 when the switching valve 16 is switched to the water stop state, and closes the hot water inlet 22a and the water inlet 22b. For this reason, it is possible to simultaneously close the hot water inlet 22a and the water inlet 22b and switch water discharged from the currant 12 or the shower head 14 by a single operation on the switching valve 16.

  Moreover, in the hot / cold water mixing faucet device 1 of this embodiment, the hot / cold water mixing chamber 21 includes the hot water side sheet portion 22c that forms part of the hot water inlet 22a and the water side sheet that forms part of the water inlet 22b. A portion 25a is provided. Further, the main valve body 30 is slid between a position where it abuts on the hot water side sheet portion 22c and a position where it abuts on the water side sheet portion 25a, so that the hot water mixing chamber 21 is moved from the hot water inlet 22a and the water inlet 22b. It is comprised so that the quantity of the hot water and water which each flow in may be adjusted. The cam member 27 and the sliding sleeve 25 which are a part of the spouting water switching mechanism slide the water-side sheet portion 25a when the water-side sheet portion 25a is switched, so that the main valve body 30 is moved to the hot water-side sheet portion. The hot water inflow port 22a and the water inflow port 22b are closed by simultaneously abutting both the 22c and the water side sheet portion 25a. For this reason, each inlet can be closed, without providing the special valve body for closing the hot water inlet 22a and the water inlet 22b.

Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, about the member same as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
FIG. 9 is an enlarged sectional view showing the hot water supply leg 4 in the present embodiment. In the present embodiment, the distal end portion of the intake valve body 110 is provided with a pressing portion 122 that can be operated with a finger. The pressing portion 122 is provided so as to protrude by a distance A from the stop cock end surface 112c in a state where the intake valve body 110 is in the water stop position.

FIG. 10 is a cross-sectional view showing a state where the pressing portion 122 is pressed from the outside with a finger or the like. When the pressing portion 122 is pressed, the intake valve body 110 also moves downward in the drawing. As a result, the intake valve body packing 110a is separated from the inner wall surface of the central bore 109d and the intake valve is opened. As a result, as in the case where negative pressure is generated, the intake valve is opened, so that the outside air flows into the pipe through the path indicated by the arrow in FIG. 10, and is upstream of the hot water inlet 22a. The hot water staying in is discharged. The same applies when the water supply leg 6 is provided.
By configuring in this way, even if the intake valve body 110 is fixed and the intake valve body 110 is difficult to operate, by operating the pressing portion 122, it is possible to reliably intake air and drain water. It becomes possible to do.

  As mentioned above, although preferable embodiment of this invention was described, a various change can be added to embodiment mentioned above. In particular, in the embodiment described above, the curan 12 is provided as the first water discharge unit, the shower head 14 is provided as the second water discharge unit, and the drainage unit 18 is provided. However, as a modification, the drainage unit 18 is omitted. be able to. In this case, when the hot / cold water mixing faucet device 1 is brought into the water-stopping state, hot water in the hot / cold water mixing chamber 21 is discharged from one water discharge portion, and outside air is sucked from the other water discharge portion, so The inside of the mixing chamber 21 is drained. According to this modification configured as described above, the present invention can be applied to the most general configuration of the hot and cold water mixing faucet apparatus including the currant and the shower head without significant changes.

  In any of the above-described embodiments, the water stop cock is provided with the pressure regulating valve, but may be configured without the pressure regulating valve. In the above-described embodiment, the intake valve body 110 is biased toward the valve opening side by the intake valve biasing spring 116, but the intake valve biasing spring biases the intake valve body toward the valve closing side. It can also be provided. In this case, the intake valve body is moved to the valve opening side due to the negative pressure generated in the pipe, and the outside air is introduced into the pipe. Alternatively, the member that urges the intake valve body can be omitted. In this case, the intake valve body is moved to the valve closing side by the supply water pressure acting on the pipe, and when the pressure in the pipe becomes negative, the intake valve body is moved to the valve opening side.

  In the above-described embodiment, the first water discharger includes the curan 12, the second water discharger includes the shower head 14, and the drainage unit 18. However, as a modification, the first water discharger or the first water discharger is provided. Either one of the two water dischargers can be omitted. In this case, when the hot / cold water mixing faucet device 1 is set to the water-stopped state, hot water in the hot / cold water mixing chamber 21 is discharged from the drainage section 18 and outside air is sucked from a single water discharge section, so The inside of the mixing chamber 21 is drained. Further, according to this modified example configured as described above, since the remaining water in the hot and cold water mixing chamber 21 is discharged from the drainage part 18, the hot water and the hot water are provided by providing the drainage part 18 at a position that is not easily noticeable by the user. Water can be drained without impairing the quality of the mixed faucet device 1.

  In any of the above-described embodiments, the water faucet device is provided with the stop cock 104. However, the so-called single faucet device or the single lever faucet is provided with the stop cock 104. You can also.
