[0006] Problems to be solved by the invention

[0007] However, in conventional faucet systems like the one described above, not only the cold and hot water supply connections, but also the outlet connection, are connected to the bathroom wall. This can lead to dimensional errors in the combination of these connections. For example, when four or more connections are connected to the same wall, the impact of dimensional errors in the combination of these connections cannot be ignored. This can sometimes make installation of the faucet body difficult, leading to the possibility of poor construction.

[0008] An object of one aspect of the embodiment is to provide a water faucet device that can absorb errors in the connection axis direction, suppress construction defects, and improve construction efficiency.

[0009] Means used to solve problems

[0010] A faucet device according to one embodiment of the present invention comprises: a plurality of water spouting parts; a faucet main body fixed to a wall inside a bathroom and supplying bath water to the plurality of water spouting parts; and a plurality of water outlet pipes arranged outside the bathroom and respectively connected to the plurality of water spouting parts and the faucet main body, the faucet main body comprising: a bath water mixing part for mixing bath water; a hot water supply connection part connected to a hot water supply component arranged on the wall of the bathroom; a cold water supply connection part connected to a cold water supply component arranged on the wall of the bathroom; a first water spouting connection part connected to a water outlet component arranged on the wall of the bathroom; and a second water spouting connection part connected to a water outlet component arranged on the wall of the bathroom, at least one of the hot water supply connection part, the cold water supply connection part, the first water spouting connection part, and the second water spouting connection part being movable in a connection axis direction.

[0011] With this structure, since at least one of the hot water supply connection, the cold water supply connection, the first water discharge connection, and the second water discharge connection is movable in the connection axis direction, the position of the component connected to the movable connection portion in the connection axis direction can be adjusted. This can reduce errors in the connection axis direction when connecting the faucet body (functional component) to piping such as a water outlet pipe located outside the bathroom, thereby preventing installation errors and improving workability.

[0012] Furthermore, in the above-mentioned faucet device, any three of the hot water supply connection part, the cold water supply connection part, the first water spouting connection part, and the second water spouting connection part are restricted from moving in the connection axis direction, and the remaining connection parts are movable in the connection axis direction.

[0013] According to such a structure, since the positions of the remaining connection parts in the connection axis direction relative to the imaginary triangle formed by the three connection parts whose movement in the connection axis direction is restricted can be adjusted, all the connection parts can be located in the same plane. Therefore, the error in the connection axis direction when the faucet main body as the functional part is connected to the piping such as the water outlet pipe arranged outside the bathroom can be effectively absorbed, poor construction can be suppressed, and compared with the case where all the connection parts are made movable, the number of places where the position needs to be adjusted can be reduced, thereby improving the construction performance.

[0014] Furthermore, in the above-mentioned water faucet device, the hot water supply connection portion, the cold water supply connection portion, the first water spouting connection portion, and the second water spouting connection portion are all movable in the connection axis direction.

[0015] According to such a structure, since the position in the direction of the connection axis can be adjusted at each of the four connection parts, the error in the direction of the connection axis when the faucet main body as the functional part is connected to the piping such as the water outlet pipe arranged outside the bathroom can be absorbed, poor construction can be suppressed, and construction performance can be improved.

[0016] Furthermore, in the above-mentioned faucet device, the connection part movable in the connection axis direction among the hot water supply connection part, the cold water supply connection part, the first water spouting connection part, and the second water spouting connection part has a sleeve capable of adjusting the insertion amount relative to the faucet body.

[0017] According to such a configuration, errors in the connection axis direction can be absorbed by a simple configuration of adjusting the insertion amount of the sleeve.

[0018] In addition, in the above-mentioned faucet device, the connection part that can move in the direction of the connection axis among the hot water supply connection part, the cold water supply connection part, the first water spouting connection part and the second water spouting connection part has a sealing component for shaft sealing arranged between it and the sleeve, and the sealing component is retained on the outer peripheral surface of the sleeve.

[0019] According to such a structure, since it is an axis seal, compared with the case of a sealing component that maintains a face seal on the faucet body side to ensure sealing performance by the extrusion amount in the connection axis direction AX, it is easy to ensure the watertightness of the faucet body and the sleeve even if the insertion amount of the sleeve is adjusted.

[0020] In addition, in the above-mentioned faucet device, the sleeve has: a threaded portion, which is formed at the front end portion; and an intermediate portion, which is formed closer to the base end side than the threaded portion and is formed to have a diameter smaller than the diameter of the threaded portion, and the threaded portion passes through the connection portion side threaded portion after being screwed into the connection portion side threaded portion, and the connection portion side threaded portion is formed in the connection portion that can move in the connection axis direction among the hot water supply connection portion, the cold water supply connection portion, the first water spouting connection portion, and the second water spouting connection portion, and the intermediate portion holds the connection portion side threaded portion in a manner that enables the connection portion side threaded portion to move in the connection axis direction after the threaded portion passes through the connection portion side threaded portion.

[0021] With this structure, the threaded portion and the intermediate portion of the sleeve form a structure that prevents the sleeve from falling out. In this structure, the threaded portion that passes through the connection-side threaded portion after being threaded together can be prevented from falling out in the direction of the connection axis by the connection-side threaded portion, thereby preventing the sleeve from being dropped or lost during construction. Furthermore, during construction, there is no need to use fingers to prevent the sleeve from falling out, thereby improving construction efficiency. Furthermore, the intermediate portion can retain the connection-side threaded portion in a manner that allows it to move in the direction of the connection axis.

[0022] Furthermore, in the above-mentioned faucet device, movement of the hot water supply connection portion and the cold water supply connection portion in the connection axis direction is restricted.

[0023] The hot water supply connection and the cold water supply connection are primary-side connections, serving as the water supply side with high water pressure. This structure allows the primary side to be firmly connected and fixed by restricting movement of these primary-side connections in the direction of the connection axis, thereby improving the reliability of the primary-side connection.

[0024] In addition, in the above-mentioned faucet device, the connection part that can move in the direction of the connection axis among the hot water supply connection part, the cold water supply connection part, the first water spouting connection part and the second water spouting connection part is arranged on the outside of the imaginary triangle formed by the three connection parts whose movement in the direction of the connection axis is restricted.

[0025] According to this structure, the connection part movable in the connection axis direction is adjusted after fixing the connection part whose movement in the connection axis direction is restricted, thereby facilitating adjustment of the connection part movable in the connection axis direction.

[0026] In addition, in the above-mentioned faucet device, the faucet main body further includes: a third water spouting connection part, which is connected to the water outlet component arranged on the wall of the bathroom; and a fourth water spouting connection part, which is connected to the water outlet component arranged on the wall of the bathroom, the third water spouting connection part and the fourth water spouting connection part are capable of moving in the direction of the connection axis, and are arranged on the outside of an imaginary triangle formed by the three connection parts whose movement in the direction of the connection axis is restricted.

[0027] According to such a configuration, even when a connection portion movable in the connection axis direction is added, construction defects can be suppressed and construction efficiency can be improved.

[0028] In addition, in the above-mentioned faucet device, the faucet main body is arranged below the bathroom cabinet arranged inside the bathroom, and the connection part that can move in the direction of the connection axis among the hot water supply connection part, the cold water supply connection part, the first water spouting connection part, and the second water spouting connection part is a connection part on the secondary side serving as the water spouting side, and is arranged above the cold water supply connection part and the hot water supply connection part on the primary side serving as the water supply side.

[0029] According to such a structure, the connection portion movable in the connection axis direction can be adjusted from above, making it easy to adjust the position. This can suppress construction defects and improve construction efficiency.

[0043] Hereinafter, embodiments of the water faucet device disclosed in the present application will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to the embodiments shown below.

[0044] For example, Figure 1 As shown, the faucet device 1 according to the embodiment is installed in a bathroom unit 1000 serving as a bathroom. Figure 1 This is a diagram showing an example of bathroom unit 1000 in which faucet device 1 according to the embodiment is installed.

[0045] Bathroom unit 1000 includes a bathtub 1001, a first bathroom cabinet 1002, a second bathroom cabinet 1003, and a faucet device 1. It should be noted that, hereinafter, cold water discharged from faucet device 1 and mixed water of hot and cold water discharged from faucet device 1 will be referred to as "bath water" without distinguishing between them.

[0046] Hereinafter, descriptions may be made using the front-to-back direction, where the direction in which the second bathroom cabinet 1003 protrudes from the wall portion 1004a of the bathroom unit 1000 is defined as the front, and the side opposite to the front is defined as the rear. Furthermore, descriptions may also be made using the up-down direction, where the vertical direction is defined as the downward direction, and the side opposite to the downward direction is defined as the upward direction. Furthermore, descriptions may also be made using the left-right direction as a direction perpendicular to the front-to-back direction and the up-down direction.

[0047] First bathroom cabinet 1002 is mounted on wall 1004a of bathroom unit 1000. First bathroom cabinet 1002 protrudes from wall 1004a toward the interior of the bathroom. First bathroom cabinet 1002 is installed above bathroom floor 1005 of bathroom unit 1000. First bathroom cabinet 1002 houses faucet body 3 of faucet device 1.

[0048] The second bathroom cabinet 1003 is mounted on the wall 1004a. The second bathroom cabinet 1003 protrudes from the wall 1004a toward the interior of the bathroom. The second bathroom cabinet 1003 is positioned above the first bathroom cabinet 1002. For example, the second bathroom cabinet 1003 may be configured to extend above the bathtub 1001. It should be noted that the second bathroom cabinet 1003 does not necessarily extend above the bathtub 1001.

[0049] A portion of the faucet device 1 is housed in the second bathroom cabinet 1003. Specifically, a portion of the faucet 10 and a portion of the hand shower 11 of the faucet device 1 are housed in the second bathroom cabinet 1003. The spout 10a of the faucet 10 is exposed in the second bathroom cabinet 1003. The spout 10a of the faucet 10 is disposed in the second bathroom cabinet 1003 so that the bath water is discharged downward.

[0050] In addition, the shower hose 11a of the hand shower 11 of the faucet device 1 is connected to the second bathroom cabinet 1003. The shower hose 11a is connected to the shower water conduit housed in the second bathroom cabinet 1003.

[0051] The ceiling 1006 of the bathroom unit 1000 is mounted with an overhead shower head 12 of the faucet device 1 and a warm water pillar shower head 13 (Warm Pillar) of the faucet device 1. The overhead shower head 12 and the warm water pillar shower head 13 are integrally provided.

[0052] Compared to the hand shower 11, the overhead shower 12 dispenses bath water over a wider area. For example, the overhead shower 12 is designed to drench the user's entire body with bath water. The warm water jet shower 13 gathers the bath water into a single stream, straightens it, and then dispenses it. In other words, the warm water jet shower 13 straightens and dispenses the bath water so that it flows continuously in a column.

[0053] A remote control device 4 (operating unit) of the faucet device 1 is mounted on a wall portion 1004b of the bathroom unit 1000. The remote control device 4 can be mounted on a wall portion 1004a on which the first bathroom cabinet 1002 and the second bathroom cabinet 1003 are mounted.

[0054] The remote control device 4 accepts various operations of the user on the faucet body 3. Specifically, the remote control device 4 accepts the operation of setting the temperature of the bath water in the faucet body 3. The remote control device 4 accepts the operation of setting the flow rate of the bath water in the faucet body 3. The remote control device 4 accepts the operation of switching the spouting and stopping of the bath water. The remote control device 4 accepts the operation of switching the spouting port of the bath water. When operated by the user, the remote control device 4 sends the operation signal corresponding to each operation to the controller 7 of the faucet device 1 (see Figure 3 ).

[0055] For example, Figure 2 As shown, the remote control device 4 includes a temperature adjustment button 41 , a water volume adjustment button 42 , and a switching button 43 . Figure 2 It is a front view showing the remote control device 4.

[0056] The temperature adjustment buttons 41 are used to adjust the temperature of the mixed water in the faucet body 3. The temperature adjustment buttons 41 include a high temperature button 41a and a low temperature button 41b. The high temperature button 41a is used to increase the temperature of the mixed water. The low temperature button 41b is used to decrease the temperature of the mixed water. It should be noted that the remote control 4 displays the set temperature of the mixed water on the first display 45a. When the high temperature button 41a or the low temperature button 41b is pressed, the display on the first display 45a changes according to the operation of the respective buttons 41a and 41b.

[0057] It should be noted that the temperature of the mixed water in the faucet body 3 can be adjusted within a predetermined temperature range. If the low temperature button 41b is operated and the set temperature of the mixed water is lower than the lowest temperature in the predetermined temperature range, the faucet body 3 does not mix hot water with cold water, but instead dispenses cold water.

[0058] The water volume adjustment buttons 42 are buttons for adjusting the flow rate of the bath water discharged from the faucet device 1. The water volume adjustment buttons 42 include a water increase button 42a and a water decrease button 42b. The water increase button 42a is a button for increasing the flow rate of the bath water. The water decrease button 42b is a button for decreasing the flow rate of the bath water. It should be noted that the remote control device 4 displays the set state of the bath water volume on the second display unit 45b. When the water increase button 42a or the water decrease button 42b is operated, the display on the second display unit 45b changes according to the operation of the respective buttons 42a and 42b. It should be noted that the flow rate of the bath water discharged from the faucet device 1 can be adjusted within a specified flow rate range.

[0059] The switch button 43 is used to switch between discharging and stopping bath water in the faucet device 1. Furthermore, the switch button 43 is used to switch the bath water outlet in the faucet device 1. The switch button 43 includes a faucet button 43a, a hand shower button 43b, an overhead shower button 43c, and a warm water jet shower button 43d. The user presses each button 43a-43d to switch between "ON" and "OFF."

[0060] When the buttons 43a to 43d of the switching button 43 are "off", bath water is not discharged. That is, the faucet device 1 is in a water-stopping state.

[0061] When the switch button 43 is switched from the "off" state to the "on" state by pressing any of the switch buttons 43, the bath water is discharged.

[0062] When any one of the switch buttons 43 is in the “on” state, if the other switch button 43 is pressed, the switch button 43 in the “on” state is changed, thereby switching the spouting port of the bath water.

[0063] For example, when hand shower button 43b is on, bath water flows from hand shower 11. In this state, pressing faucet button 43a switches hand shower button 43b to off, and faucet button 43a to on. This switches the bath water outlet from hand shower 11 to faucet 10, and bath water flows from faucet 10.

[0064] When the switch button 43 in the "on" state is pressed again, the pressed switch button 43 is turned "off", and the buttons 43a to 43d of the switch button 43 are all turned "off", thereby stopping the supply of bath water. In other words, the faucet device 1 changes from the water spouting state to the water stopping state.

[0065] It should be noted that each button 43a to 43d is configured so that the user can recognize the state of "on" and "off." For example, the switch button 43 in the "on" state is lit, and the switch button 43 in the "off" state is unlit.

[0066] It should be noted that, while the faucet device 1 is described here as an example in which bath water is dispensed from the overhead shower head 12, the warm water jet shower head 13, the hand shower head 11, and the faucet 10, the present invention is not limited thereto. For example, the faucet device 1 may be configured without the overhead shower head 12 and the warm water jet shower head 13.

[0067] Next, refer to Figure 3, the outline of the water faucet device 1 according to the embodiment will be described. Figure 3 1 is a schematic block diagram showing the water faucet device 1 according to the embodiment. Figure 3 In the figure, the solid arrows represent the flow of bath water, and the dotted lines represent the communication lines.

[0068] The water faucet device 1 includes a plurality of water discharge units 2 , a faucet body 3 , a remote control device 4 , and a communication unit 5 .

[0069] The plurality of water spouting units 2 include a faucet 10 , a hand shower 11 , an overhead shower 12 , and a warm water jet shower 13 .

[0070] The faucet main body 3 includes a mixing faucet unit 20 , a water spout switching portion 30 , and a controller 7 .

[0071] The mixing faucet unit 20 includes a bath water mixing unit 50 and a flow rate adjustment unit 60. Hot water is supplied to the bath water mixing unit 50 from a hot water supply source 80. Cold water is supplied to the bath water mixing unit 50 from a cold water supply source 81. A stopcock 84 is provided in the flow path (hot water supply pipe 82) between the bath water mixing unit 50 and the hot water supply source 80. A stopcock 85 is also provided in the flow path (cold water supply pipe 83) between the bath water mixing unit 50 and the cold water supply source 81.

[0072] The bath water mixing unit 50 mixes hot water supplied from the hot water supply source 80 with cold water supplied from the cold water supply source 81. Specifically, the bath water mixing unit 50 switches whether to mix hot water with cold water. Furthermore, the bath water mixing unit 50 adjusts the ratio of hot water to cold water, thereby adjusting the temperature of the mixed water.

[0073] The bath water mixing unit 50 includes a motor 51. For example, the motor 51 is a stepping motor. The bath water mixing unit 50 drives the motor 51 according to the operation of the temperature adjustment button 41 of the remote control device 4, thereby driving the temperature control valve 210 (see Figure 7 ), toggle whether to mix hot water with cold water.

[0074] Furthermore, the bath water mixing unit 50 drives the motor 51 in response to the operation of the temperature adjustment button 41 on the remote control 4, thereby driving the temperature control valve 210 to adjust the ratio of hot water mixed with cold water. Furthermore, even when the temperature adjustment button 41 is not operated, for example, if the temperature of the hot water changes and the temperature of the mixed water changes, the bath water mixing unit 50 can automatically adjust the temperature of the mixed water by adjusting the ratio of the flow rate of hot water to the flow rate of cold water in accordance with the temperature of the mixed water.

[0075] Bath water flows from the bath water mixing unit 50 into the flow rate adjustment unit 60. When bath water is discharged from the discharge unit 2, the flow rate adjustment unit 60 adjusts the flow rate of the discharged bath water.

[0076] The flow regulating unit 60 includes a motor 61. For example, the motor 61 is a stepping motor. The flow regulating unit 60 drives the motor 61 according to the operation of the water volume regulating button 42 of the remote control device 4, thereby driving the flow regulating valve 230 (see Figure 7 ) to adjust the flow of bath water.

[0077] The spouting switching unit 30 switches the spouting and stopping of bath water flowing from the mixing faucet unit 20. Specifically, the spouting switching unit 30 switches the spouting and stopping of bath water from the spouting unit 2. Furthermore, the spouting switching unit 30 switches the spouting port for bath water. The faucet device 1 switches the spouting and stopping of bath water from the spouting unit 2 via the spouting switching unit 30, and adjusts the flow rate of bath water during spouting via the flow regulating unit 60.

[0078] The jetting switching unit 30 includes a plurality of electromagnetic valves 31 to 35. Specifically, the jetting switching unit 30 includes a first electromagnetic valve 31, a second electromagnetic valve 32, a third electromagnetic valve 33, and a fourth electromagnetic valve 34. The jetting switching unit 30 may include a fifth electromagnetic valve 35.

[0079] The first to fourth electromagnetic valves 31 to 34 are switched to “OFF” or “ON” according to the operation of the switching button 43 .

[0080] When the first to fourth solenoid valves 31 to 34 are "closed," bath water is not discharged from the water discharge unit 2. In other words, when the first to fourth solenoid valves 31 to 34 are "closed," the supply of bath water is stopped. When any of the first to fourth solenoid valves 31 to 34 is "open," bath water is discharged from the water discharge unit 2 corresponding to the "open" solenoid valve.

[0081] The first solenoid valve 31 switches the flow of bath water from the faucet 10 on and off. The second solenoid valve 32 switches the flow of bath water from the hand shower 11 on and off. The third solenoid valve 33 switches the flow of bath water from the overhead shower 12 on and off. The fourth solenoid valve 34 switches the flow of bath water from the warm water jet shower 13 on and off.

[0082] For example, when the first electromagnetic valve 31 is “open” and the second to fourth electromagnetic valves 32 to 34 are “closed”, bath water is discharged from the faucet 10 .

[0083] The fifth solenoid valve 35 switches to "off" or "on" according to the operation of the external device 89 (for example, a multi-function remote control device installed in the bathroom). It should be noted that the fifth solenoid valve 35 can also be switched to "off" or "on" according to the operation of the remote control device 4. The fifth solenoid valve 35 is a valve used to discharge excess water in the hose or piping of the hand shower 11, etc., and is usually maintained in the "closed" position. In other words, the fifth solenoid valve 35 is set to "open" only when excess water treatment is being performed. When the fifth solenoid valve 35 is "open", excess water is discharged from the excess water discharge flow path 88.

[0084] The controller 7 controls the motors 51 and 61 and the first to fourth electromagnetic valves 31 to 34 according to the operation of the faucet body 3 received through the operation of the remote control 4. In addition, the controller 7 controls the fifth electromagnetic valve 35 according to the operation of the external device 89, for example.

[0085] For example, the controller 7 includes a microcomputer or various circuits including a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). It should be noted that the controller 7 may include hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0086] The communication unit 5 receives operation signals from the remote control device 4 and the external device 89 and transmits the received operation signals to the controller 7. The remote control device 4 and the external device 89 are connected to the communication unit 5 via wired communication or wireless communication. The controller 7 is connected to the communication unit 5 via wired communication or wireless communication.

[0087] Next, refer to Figure 4 , the faucet main body 3 is described. Figure 4 The faucet main body 3 is a perspective view showing the faucet main body 3. The faucet main body 3 is composed of a mixing faucet unit 20, a water spouting switching unit 30, and a controller 7 (see Figure 3 ) is further provided with a flow path unit 70. The faucet body 3 is attached to the wall portion 1004a of the bathroom unit 1000 through the flow path unit 70 (see Figure 1 ).

[0088] The flow path unit 70 is formed so that the hot water source 80 (see Figure 3 ) flows into the flow path of the mixing faucet unit 20, so that the hot water supplied by the cold water source 81 (refer to Figure 3 ) flows into the flow path of the mixing faucet unit 20, and the flow path of the bath water flowing from the mixing faucet unit 20 into each water spouting unit 2. It should be noted that the flow path unit 70 is provided with a water spouting switching unit 30. In addition, the flow path unit 70 is provided with a water stopper 84 and a water stopper 85 (see Figure 3 ). In addition, the flow path unit 70 is provided with a surplus water discharge flow path 88.

[0089] In the faucet body 3, the flow path unit 70 is provided at the rear, and the mixing faucet unit 20 is provided in front of the flow path unit 70. It should be noted that a portion of the flow path unit 70 is provided above the mixing faucet unit 20. Furthermore, a controller box 201 housing the controller 7 is provided in front of the mixing faucet unit 20.

[0090] Next, refer to Figures 5 to 7 , the mixing faucet unit 20 will be described. Figure 5 It is a perspective view showing the mixing faucet unit 20 . Figure 6 It is a front view showing the mixing faucet unit 20 . Figure 7 yes Figure 6 A stereogram of the VII-VII section.

[0091] The mixing faucet unit 20 is configured to extend in the left-right direction. A motor box 200a is provided at one end of the mixing faucet unit 20 in the left-right direction, specifically the left end, to house the motor 51 of the bath water mixing unit 50. A motor box 200b is provided at the other end of the mixing faucet unit 20 in the left-right direction, specifically the right end, to house the motor 61 of the flow rate adjustment unit 60.

[0092] The bath water mixing unit 50 switches whether to mix the hot water supplied from the hot water supply path 203 with the cold water supplied from the cold water supply path 202 by moving the temperature regulating valve 210 (regulating valve) in the left-right direction.

[0093] For example, the thermostatic valve 210 contacts the tank 211 provided on the left side of the thermostatic valve 210 , whereby the supply of hot water is blocked by the thermostatic valve 210 and the hot water is not mixed with the cold water supplied from the cold water supply path 202 .

[0094] Furthermore, since the thermostatic valve 210 is located away from the tank 211 , the supply of hot water is not blocked by the thermostatic valve 210 . Therefore, the hot water supplied from the hot water supply path 203 is mixed with the cold water supplied from the cold water supply path 202 .

[0095] The thermostatic valve 210 is biased away from the tank 211 by the thermostatic spring 212. Furthermore, the thermostatic valve 210 is biased toward the tank 211 by the bias spring 213. Specifically, the thermostatic valve 210 moves in the left-right direction based on the magnitude relationship between the biasing force of the thermostatic spring 212 and the biasing force of the bias spring 213.

[0096] The temperature-sensitive spring 212 is a spring whose spring constant changes according to temperature and is made of, for example, a shape memory alloy. The bias spring 213 is a spring whose spring constant is substantially constant with respect to temperature.

[0097] When the biasing force of the biasing spring 213 is greater than the biasing force of the temperature-sensitive spring 212, the thermostatic valve 210 moves toward the box 211, that is, to the left.

[0098] When the urging force of the temperature-sensitive spring 212 is greater than the urging force of the biasing spring 213 , the temperature-regulating valve 210 moves rightward so as to be separated from the tank 211 .

[0099] When the urging force of the temperature-sensing spring 212 is equal to the urging force of the bias spring 213 , the thermostatic valve 210 does not move in the left-right direction but remains at a position where the urging force of the temperature-sensing spring 212 and the urging force of the bias spring 213 are balanced.

[0100] The other end of the temperature-sensing spring 212, opposite to the one end abutting the thermostatic valve 210, abuts against a gasket 214. The gasket 214 is connected to a rotating shaft 216 via a main shaft 215. The main shaft 215 is rotatably supported by the housing 211, converting the rotational motion of the rotating shaft 216 into horizontal linear motion of the gasket 214. Consequently, the gasket 214 moves horizontally in response to the rotation of the rotating shaft 216.

[0101] The rotating shaft 216 is connected to the motor 51 via a transmission mechanism. The transmission mechanism is housed in the motor case 200a. The transmission mechanism includes a first gear connected to the rotating shaft of the motor 51 and a second gear connected to the rotating shaft 216. The first gear and the second gear mesh with each other. The rotating shaft 216 transmits the rotation of the rotating shaft of the motor 51 through the transmission mechanism. It should be noted that the transmission mechanism is the same as the transmission mechanism in the flow control unit 60 described later.

[0102] In the bath water mixing unit 50, the bushing 214 moves left and right in accordance with the rotational position of the rotating shaft 216, that is, the rotational position of the rotating shaft of the motor 51. Specifically, the bath water mixing unit 50 can adjust the position of the thermostatic valve 210 to a position where the applied force of the temperature-sensing spring 212 and the applied force of the biasing spring 213 are balanced, in accordance with the rotational position of the rotating shaft of the motor 51. Thus, when dispensing mixed water, the bath water mixing unit 50 can set the temperature of the mixed water to a set temperature corresponding to the rotational position of the rotating shaft of the motor 51.

[0103] Furthermore, when dispensing mixed water, for example, if the temperature of the hot water changes and the temperature of the mixed water changes, the temperature-sensitive spring 212 expands and contracts according to the temperature of the mixed water, causing the thermostatic valve 210 to move left and right, automatically changing the equilibrium position of the thermostatic valve 210. This allows the amount of hot water and cold water in the mixed water to be adjusted, automatically adjusting the temperature of the mixed water.

[0104] The bath water mixing unit 50 communicates with the flow rate adjustment unit 60 through the communication hole 220 . Bath water flows from the bath water mixing unit 50 into the flow rate adjustment unit 60 through the communication hole 220 .

[0105] The flow regulating unit 60 rotates the flow regulating valve 230 (regulating valve) about an imaginary axis extending in the left-right direction, thereby changing the area of ​​communication between the opening of the restricting member 221 and the opening of the flow regulating valve 230, thereby changing the opening of the flow regulating valve 230. The flow regulating unit 60 adjusts the flow rate of bath water flowing out of the mixing faucet unit 20, that is, the flow rate of the bath water flowing out of the spouting unit 2 (see FIG. 2 ). Figure 3 )The flow rate of spitted bath water.

[0106] Next, refer to Figure 8 and Figure 9 , further explain the faucet main body 3. Figure 8 It is an explanatory diagram of the connection of the faucet main body 3. Figure 9 It is a perspective view showing the faucet main body 3 . Figure 9 The faucet main body 3 is shown as viewed from the rear.

[0107] like Figure 8 As shown, the faucet body 3 is fixed to the bathroom unit 1000 (see Figure 1 ) of the wall W B The faucet body 3 includes a faucet 10 (see Figure 3 )、Handheld showerhead 11 (refer to Figure 3 ), overhead shower 12 (refer to Figure 3 ) and warm water shower 13 (refer to Figure 3 ) etc. multiple jetting units 2 (refer to Figure 3 )Supply of bath water.

[0108] The faucet body 3 is connected to the wall W disposed on the bathroom unit 1000. B The connecting member 90 is connected to the faucet body 3. The connecting member 90 includes a hot water supply member 91, a cold water supply member 92, and a water outlet member 93. The water outlet member 93 is connected to a water outlet pipe 94 disposed outside the bathroom unit.

[0109] like Figure 8 As shown, the faucet body 3 includes a hot water supply connection portion 110, a cold water supply connection portion 111, a first water spouting connection portion 112, a second water spouting connection portion 113, a third water spouting connection portion 114, and a fourth water spouting connection portion 115. The hot water supply connection portion 110 is connected to the hot water supply member 91. The cold water supply connection portion 111 is connected to the cold water supply member 92. The first water spouting connection portion 112, the second water spouting connection portion 113, the third water spouting connection portion 114, and the fourth water spouting connection portion 115 are each connected to the water outlet member 93.

[0110] The flow path unit 70 is provided with a hot water supply connection portion 110, a cold water supply connection portion 111, a first water jetting connection portion 112, a second water jetting connection portion 113, a third water jetting connection portion 114, and a fourth water jetting connection portion 115. As described above, the flow path unit 70 has a configuration in which the hot water supply source 80 (see FIG. 1 ) is connected to the flow path unit 70. Figure 3 ) supplied hot water flows into the mixing faucet unit 20 (refer to Figure 4 ) of the flow path, so that the cooling water source 81 (refer to Figure 3 ) flows into the flow path of the mixing faucet unit 20, and the bath water flows from the mixing faucet unit 20 into the flow path of each spouting part 2.

[0111] Furthermore, the flow path unit 70 includes a water jet switching unit 30 (see Figure 4 ), water stopper 84 and water stopper 85 (refer to Figure 3 ) and excess water discharge passage 88 (see Figure 4 ) etc. It should be noted that the faucet body 3 is installed on the wall W B In this case, the rod portion 95 provided on the connecting member 90 is inserted into the cylindrical receiving portion 116 provided on the back surface of the flow path unit 70 to achieve positioning.

[0112] like Figure 9As shown, in the faucet body 3, at least one of the hot water supply connection portion 110, the cold water supply connection portion 111, the first water spouting connection portion 112, and the second water spouting connection portion 113 is movable in the connection axis direction AX. Furthermore, in the faucet body 3, at least one of the hot water supply connection portion 110, the cold water supply connection portion 111, the first water spouting connection portion 112, the second water spouting connection portion 113, the third water spouting connection portion 114, and the fourth water spouting connection portion 115 is movable in the connection axis direction AX.

[0113] Furthermore, in the faucet body 3, movement in the connection axis direction AX is restricted for any three of the hot water supply connection portion 110, the cold water supply connection portion 111, the first water spouting connection portion 112, and the second water spouting connection portion 113. In the faucet body 3, the remaining connection portions are movable in the connection axis direction AX.

[0114] The connection part that can move in the connection axis direction AX among the hot water supply connection part 110, the cold water supply connection part 111, the first water discharge connection part 112, and the second water discharge connection part 113 includes a movable part 400 described later. The movable part 400 includes a sleeve 420 (see Figure 11 ), wherein the sleeve 420 will be described later.

[0115] Furthermore, in the faucet body 3, the hot water supply connection part 110 and the cold water supply connection part 111 are restricted from moving in the connection axis direction AX. The hot water supply connection part 110 and the cold water supply connection part 111 include a fixing part 300 to be described later.

[0116] In addition, if Figure 9 As shown, in the faucet body 3, the connection parts that can move in the connection axis direction AX among the hot water supply connection part 110, the cold water supply connection part 111, the first water discharge connection part 112, and the second water discharge connection part 113 are arranged on an imaginary triangle T formed by three points (P1 to P3) of the three connection parts whose movement in the connection axis direction AX is restricted. V outside.

[0117] According to such a structure, since at least one of the hot water supply connection part 110, the cold water supply connection part 111, the first water discharge connection part 112, and the second water discharge connection part 113 can be moved in the connection axis direction AX, the water discharge member 93 connected to the connection part that can be moved in the connection axis direction AX can be adjusted (see Figure 8 ) and other components in the connection axis direction AX. Thus, it is possible to absorb the faucet body 3 as a functional part connected to the bathroom unit 1000 (refer to Figure 1 ) of the external water outlet pipe 94 (refer to Figure 8) etc., can suppress poor construction and improve construction performance.

[0118] Furthermore, since the virtual triangle T formed by the three points (P1 to P3) of the three connecting parts whose movement in the connecting axis direction AX is restricted can be adjusted, V As for the positions of the remaining connection parts in the connection axis direction AX, all the connection parts can be located in the same plane. Therefore, the error in the connection axis direction AX when the faucet main body 3 as the functional part is connected to the piping such as the water outlet pipe 94 arranged outside the bathroom unit 1000 can be effectively absorbed, poor construction can be suppressed, and compared with the case where all the connection parts are made movable, the number of places where the position needs to be adjusted can be reduced, thereby improving the construction performance.

[0119] Furthermore, in the connection portion that can move in the connection axis direction AX, the sleeve 420 (see Figure 11 ) insertion amount such a simple structure can absorb the error in the connection axis direction AX.

[0120] Furthermore, the hot water supply connection 110 and the cold water supply connection 111 are primary-side connections, serving as the water supply side with high water pressure. Therefore, by restricting movement of the primary-side connection in the connection axis direction AX, the primary side can be firmly connected and fixed, thereby improving the reliability of the primary-side connection.

[0121] Furthermore, by adjusting the connecting portion movable in the connecting axis direction AX after fixing the connecting portion whose movement in the connecting axis direction AX is restricted, the connecting portion movable in the connecting axis direction AX can be easily adjusted. This can prevent poor construction and improve construction efficiency.

[0122] Furthermore, the third jetting connection portion 114 and the fourth jetting connection portion 115 are movable in the connection axis direction AX. Figure 9 As shown, the third jetting connection portion 114 and the fourth jetting connection portion 115 are arranged in an imaginary triangle T formed by three points (P1 to P3) of the three connection portions whose movement in the connection axis direction AX is restricted. V Thus, even when a connection portion that can move in the connection axis direction AX is added, poor construction can be suppressed and construction performance can be improved.

[0123] It should be noted that, in the faucet body 3 , the hot water supply connection portion 110 , the cold water supply connection portion 111 , the first water spouting connection portion 112 , and the second water spouting connection portion 113 may all be movable in the connection axis direction AX.

[0124] According to such a structure, since the position of the connection axis direction AX can be adjusted at each of the four connection parts, the error in the connection axis direction AX when the faucet main body 3 as the functional part is connected to the piping such as the water outlet pipe 94 arranged outside the bathroom unit 1000 can be absorbed, poor construction can be suppressed, and construction performance can be improved.

[0125] In addition, the faucet main body 3 is arranged in a position larger than that arranged in the bathroom unit 1000 (see Figure 1 ) of the interior of the bathroom cabinet (the first bathroom cabinet 1002 and the second bathroom cabinet 1003) (refer to Figure 1 In the faucet body 3, the connection portion movable in the connection axis direction AX among the hot water supply connection portion 110, the cold water supply connection portion 111, the first water spouting connection portion 112, and the second water spouting connection portion 113 is a connection portion on the secondary side, which serves as the water spouting side, and is arranged above the cold water supply connection portion 111 and the hot water supply connection portion 110, which serve as the water supply side.

[0126] According to such a structure, it is easy to adjust the position of the connection part which can move in the connection axis direction AX. This can suppress construction defects and improve construction efficiency.

[0127] Next, refer to Figure 10 and Figure 11 , the fixed portion 300 and the movable portion 400 in the faucet body 3 are described. Figure 10 3 is a side sectional view showing the fixing portion 300 . Figure 11 It is a side sectional view showing the movable portion 400 .

[0128] The fixing portion 300 is used to realize a fixing structure, which is used to limit the faucet body 3 (refer to Figure 9 ) moves in the direction of the connecting axis AX. Figure 10 As shown, the fixing portion 300 is provided at a certain connection portion (eg, the hot water supply connection portion 110 ) and includes a cap nut 310 , a sleeve 320 , sealing members 330 and 340 , and the contact portion 110 a of the hot water supply connection portion 110 .

[0129] The cap nut 310 is formed in a cylindrical shape and is attached to one end portion (base end portion) of the sleeve 320 so as to cover the one end portion in the connection axis direction AX.

[0130] The sleeve 320 is cylindrical. It includes a flange 321 and a retaining portion 322. The flange 321 is provided at one end of the sleeve 320. The flange 321 extends outward from the outer circumference of the sleeve 320. The retaining portion 322 is provided on the outer circumference of the sleeve 320. The retaining portion 322 is a recessed portion extending along the circumference of the outer circumference of the sleeve 320.

[0131] The sealing member 330 is formed in an annular shape. It is held by the retaining portion 322 and is held between the outer circumferential surface of the sleeve 320, which serves as a sealing surface, and the inner circumferential surface of the hot water supply connection portion 110. The sealing member 340 is formed in an annular shape. It is held by the end surface (base end surface) of one end portion (base end portion) of the sleeve 320.

[0132] The abutment portion 110a of the hot water supply connection portion 110 is formed as a step on the inner surface of the hot water supply connection portion 110. The end surface (front end surface) of the other end portion (front end portion) of the sleeve 320 abuts against the abutment portion 110a. This restricts movement of the sleeve 320 in the connection axis direction AX.

[0133] The movable portion 400 is used to realize a movable structure for moving the faucet body 3 (see Figure 9 ) can move in the connection axis direction AX. Figure 11 As shown, the movable part 400 is provided at a connection part (for example, the first water jetting connection part 112 ) and includes a cap nut 410 , a sleeve 420 , sealing members 430 and 440 , and the connection-side threaded portion 112 a of the first water jetting connection part 112 .

[0134] The cap nut 410 is formed in a cylindrical shape and is attached to one end portion (base end portion) of the sleeve 420 so as to cover the one end portion in the connection axis direction AX.

[0135] The sleeve 320 is cylindrical. The sleeve 420 includes a flange 421, a retaining portion 422, a threaded portion 423, and an intermediate portion 424. The flange 421 is provided at one end of the sleeve 420. The flange 421 extends outward from the outer circumference of the sleeve 420. The retaining portion 422 is provided on the outer circumference of the sleeve 420. The retaining portion 422 is a recessed portion extending along the circumference of the outer circumference of the sleeve 420.

[0136] The threaded portion 423 is formed at the other end (front end) of the sleeve 420. The intermediate portion 424 is formed on the outer circumferential surface of the sleeve 420, closer to one end of the sleeve 420 than the threaded portion 423. The diameter of the sleeve 420 is reduced in the intermediate portion 424, creating a space between the sleeve 420 and the inner surface of the first water jetting connection portion 112.

[0137] The sealing member 430 is formed into an annular shape. It is held by the retaining portion 422 and is retained between the outer circumferential surface of the sleeve 420, which serves as the sealing surface, and the inner circumferential surface of the first water spouting connection portion 112. In this case, since it is a shaft seal, compared to a surface seal where the sealing performance is ensured by squeezing in the connection axis direction AX, it is easier to maintain watertightness between the faucet body 3 and the sleeve 420 even when adjusting the insertion distance of the sleeve 420.

[0138] The sealing member 440 is formed in an annular shape and is held on an end surface (base end surface) of one end portion (base end portion) of the sleeve 420 .

[0139] The threaded portion 423 of the sleeve 420 is threadedly engaged with the connection-side threaded portion 112a formed near the sealing surface of the first water jetting connection 112. The threaded portion 423 passes through the connection-side threaded portion 112a by deepening the threaded engagement with the connection-side threaded portion 112a. In this manner, the connection-side threaded portion 112a is retained by the intermediate portion 424. Thus, the sleeve 420 is prevented from falling out at the other end by the threaded portion 423, and can be moved in the connection axis direction AX by the length of the intermediate portion 424 along the connection axis direction AX.

[0140] With this structure, the threaded portion 423 and the intermediate portion 424 of the sleeve 420 form a fall-off prevention structure for the sleeve 420. In this fall-off prevention structure, the threaded portion 423, which is threadedly engaged with the connection-side threaded portion 112a, is prevented from falling off in the connection axis direction AX by the connection-side threaded portion 112a. This prevents the sleeve 420 from falling off or dropping during construction, thereby significantly improving construction efficiency. Furthermore, the intermediate portion 424 can retain the connection-side threaded portion 112a in a manner that allows the connection-side threaded portion 112a to move in the connection axis direction AX.

[0141] In addition, the movable part 400 has a gap 450 between the inner surface of the cap nut 410 and the outer surface of the sleeve 420. In addition, the sleeve 420 and the water outlet member 93 (see Figure 8 ) and other components to perform surface sealing.

[0142] This structure ensures watertightness in the hot water supply connection 100, the cold water supply connection 101, the first water jetting connection 102, and the second water jetting connection 103 while accommodating radial deviations in the sleeve 420 of the movable part 400. This prevents construction defects and improves workability.
