Abstract
Description
[Technical Field]
[0001] The disclosed embodiments relate to a water faucet device. [Background technology]
[0002] Conventionally, a faucet device is known that includes a water discharge portion, a faucet body, and a hot water outlet pipe, and the water discharge portion and the faucet body are connected via the hot water outlet pipe located outside the bathroom (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-100427 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the conventional faucet devices described above, not only the cold water supply and hot water supply connections but also the hot water outlet connection are connected to the bathroom wall, which can lead to dimensional errors in the combination of the connections. For example, when four or more connections are connected to the same wall, the impact of dimensional errors in the combination of the connections cannot be ignored. This can make installation of the faucet body difficult, leading to the risk of poor installation.
[0005] One aspect of the embodiment aims to provide a faucet device that can absorb errors in the direction of the connection axis, suppress installation defects, and improve installation efficiency. [Means for solving the problem]
[0006] A faucet device according to one aspect of the embodiment comprises a plurality of water outlets, a faucet body fixed to the wall inside a bathroom and supplying hot water to the plurality of water outlets, and a plurality of hot water outlet pipes arranged outside the bathroom and connecting the plurality of water outlets and the faucet body, respectively. The faucet body comprises a hot water / water mixing section that mixes hot water and water, a hot water supply connection section connected to a hot water supply member arranged on the wall of the bathroom, a water supply connection section connected to a water supply member arranged on the wall of the bathroom, a first water outlet connection section connected to a hot water outlet member arranged on the wall of the bathroom, and a second water outlet connection section connected to a hot water outlet member arranged on the wall of the bathroom, and at least one of the hot water supply connection section, the water supply connection section, the first water outlet connection section and the second water outlet connection section is movable in the direction of the connection axis.
[0007] With this configuration, at least one of the hot water supply connection, cold water supply connection, first water discharge connection, and second water discharge connection is movable in the connection axis direction, making it possible to adjust the position of the component connected to the connection part that is movable in the connection axis direction. This makes it possible to absorb errors in the connection axis direction when connecting the faucet body, which serves as the functional part, to a pipe such as a hot water outlet pipe located outside the bathroom, thereby reducing installation defects and improving installation efficiency.
[0008] In addition, in the above-mentioned faucet device, any three of the hot water connection portion, the cold water supply connection portion, the first water discharge connection portion and the second water discharge connection portion are restricted from moving in the direction of the connection axis, and the remaining three are movable in the direction of the connection axis.
[0009] With this configuration, it is possible to adjust the position of the remaining connection parts in the connection axis direction relative to the virtual plane formed by the three connection parts whose movement in the connection axis direction is restricted, and all connection parts can be positioned on the same plane.This effectively absorbs errors in the connection axis direction when connecting the faucet body, which is the functional part, to piping such as a hot water outlet pipe located outside the bathroom, suppressing installation defects and reducing the number of places requiring position adjustment compared to when all connection parts are movable, thereby improving installation efficiency.
[0010] In the above-described faucet device, the hot water supply connection portion, the cold water supply connection portion, the first water discharge connection portion, and the second water discharge connection portion are all movable in the direction of the connection axis.
[0011] With this configuration, it is possible to adjust the position of each of the four connection parts in the direction of the connection axis, which makes it possible to absorb errors in the direction of the connection axis when connecting the faucet body, which is the functional part, to piping such as a hot water outlet pipe located outside the bathroom, thereby reducing installation defects and improving installation efficiency.
[0012] In addition, in the above-mentioned faucet device, the hot water connection portion, the cold water supply connection portion, the first water discharge connection portion and the second water discharge connection portion that can move in the connection axis direction have a bush that can adjust the insertion depth relative to the faucet body.
[0013] According to this configuration, the error in the direction of the connecting axis can be absorbed by a simple configuration of adjusting the insertion length of the bushing.
[0014] In addition, in the above-mentioned faucet device, the connection parts that can move in the connection axis direction, among the hot water connection part, the cold water supply connection part, the first water discharge connection part and the second water discharge connection part, have an axial seal sealing member that is arranged between the bush and the connection part, and the sealing member is held on the outer peripheral surface of the bush.
[0015] With this configuration, because it is an axial seal, watertightness of the faucet body and bushing can be easily ensured even by adjusting the insertion allowance of the bushing, compared to when a surface seal sealing member that ensures sealing performance by the crushing allowance in the connection axis direction AX is held on the faucet body side.
[0016] In addition, in the above-mentioned faucet device, the bush has a threaded portion formed at the tip end and an intermediate portion formed closer to the base end than the threaded portion and having a smaller diameter than the threaded portion, and the threaded portion passes through the connection portion side threaded portion after screwing with the connection portion side threaded portion formed on the connection portion that is movable in the connection axial direction among the hot water connection portion, the cold water supply connection portion, the first water discharge connection portion and the second water discharge connection portion, and the intermediate portion holds the connection portion side threaded portion movable in the connection axial direction after the threaded portion has passed through the connection portion side threaded portion.
[0017] With this configuration, the threaded portion and intermediate portion of the bushing act as a retaining structure for the bushing. With this retaining structure, the threaded portion that has threadedly passed through the connection-side threaded portion can be prevented from coming off in the connection axis direction by the connection-side threaded portion, thereby preventing the bushing from being dropped or lost during installation. Furthermore, work such as placing a finger on the bushing to prevent it from coming off during installation is no longer necessary, improving installation efficiency. Furthermore, the intermediate portion can hold the connection-side threaded portion movably in the connection axis direction.
[0018] In the above-described faucet device, the hot water supply connection portion and the cold water supply connection portion are restricted from moving in the direction of the connection axis.
[0019] The hot water supply connection and the cold water supply connection are primary side connection parts, which are the water supply side with high water pressure. With this configuration, movement of these primary side connection parts in the connection axis direction is restricted, allowing the primary side to be firmly connected and fixed, thereby improving the connection reliability of the primary side.
[0020] In addition, in the above-mentioned faucet device, the connection parts that can move in the connection axis direction among the hot water connection part, the cold water supply connection part, the first water discharge connection part and the second water discharge connection part are positioned outside the virtual triangle formed by the three connection parts whose movement in the connection axis direction is restricted.
[0021] According to this configuration, the connection portion that is restricted in its movement in the connection axis direction is fixed, and then the connection portion that is movable in the connection axis direction is adjusted, which makes it easy to adjust the connection portion that is movable in the connection axis direction. This makes it possible to prevent installation defects and improve installation efficiency.
[0022] In addition, in the above-mentioned faucet device, the faucet body further includes a third water discharge connection portion connected to a water discharge member arranged on the wall of the bathroom, and a fourth water discharge connection portion connected to a water discharge member arranged on the wall of the bathroom, and the third water discharge connection portion and the fourth water discharge connection portion are movable in the connection axis direction and are arranged outside an imaginary triangle formed by the three connection portions whose movement in the connection axis direction is restricted.
[0023] With this configuration, even if the number of connecting portions that can move in the connection axis direction increases, poor installation can be suppressed and installation efficiency can be improved.
[0024] In addition, in the above-mentioned faucet device, the faucet body is positioned below a counter located inside the bathroom, and the connection parts that can move in the connection axis direction among the hot water connection part, the water supply connection part, the first water discharge connection part and the second water discharge connection part are secondary side connection parts on the water discharge side, and are positioned above the primary side water supply connection part and the hot water connection part on the water supply side.
[0025] With this configuration, the connection portion that is movable in the connection axis direction can be adjusted from above, making it easy to adjust the position, thereby reducing installation defects and improving installation efficiency. [Effects of the Invention]
[0026] According to one aspect of the embodiment, the faucet device can absorb errors in the direction of the connection axis, thereby reducing installation defects and improving installation efficiency. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] The following detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. However, the present invention is not limited to the following preferred embodiments.
[0029] A faucet device 1 according to the embodiment is installed in a bathroom unit 1000 that serves as a bathroom, for example, as shown in Figure 1. Figure 1 is a diagram showing an example of a bathroom unit 1000 in which a faucet device 1 according to the embodiment is arranged.
[0030] Bathroom unit 1000 includes a bathtub 1001, a first counter 1002, a second counter 1003, and a faucet device 1. In the following description, when there is no need to distinguish between water discharged by faucet device 1 and mixed water that is a mixture of hot and cold water and discharged by faucet device 1, they will be referred to as "hot and cold water."
[0031] In the following, the direction in which the second counter 1003 protrudes from the wall 1004a of the bathroom unit 1000 is referred to as the front, and the opposite side of the front is referred to as the rear, and the vertical direction is referred to as the down, and the opposite side of the down is referred to as the up, and the direction perpendicular to the front, back, and up, and down is referred to as the left, right, and left directions.
[0032] The first counter 1002 is attached to the wall portion 1004a of the bathroom unit 1000. The first counter 1002 protrudes from the wall portion 1004a into the interior of the bathroom. The first counter 1002 is provided above the washing area floor 1005 of the bathroom unit 1000. The faucet body 3 of the faucet device 1 is housed in the first counter 1002.
[0033] The second counter 1003 is attached to the wall 1004a. The second counter 1003 protrudes from the wall 1004a into the bathroom. The second counter 1003 is provided higher than the first counter 1002. For example, the second counter 1003 is provided so as to extend above the bathtub 1001. Note that the second counter 1003 does not have to extend above the bathtub 1001.
[0034] The second counter 1003 houses a portion of the faucet device 1. Specifically, the second counter 1003 houses a portion of the faucet 10 of the faucet device 1 and a portion of the hand shower 11 of the faucet device 1. The second counter 1003 is provided so that the spout 10a of the faucet 10 is exposed. The spout 10a of the faucet 10 is provided on the second counter 1003 so that the direction of hot and cold water spouting is downward.
[0035] In addition, the shower hose 11a of the hand shower 11 of the faucet device 1 is connected to the second counter 1003. The shower hose 11a is connected to a shower water conduit housed in the second counter 1003.
[0036] An overhead shower 12 of the faucet device 1 and a warm pillar 13 of the faucet device 1 are attached to the ceiling 1006 of the bathroom unit 1000. The overhead shower 12 and the warm pillar 13 are provided integrally.
[0037] The overhead shower 12 sprays hot water over a wider area of the user than the hand shower 11. For example, the overhead shower 12 is configured so that hot water hits the entire body of the user. The warm pillar 13 collects hot water into a single stream and sprays it straight. In other words, the warm pillar 13 sprays straightened hot water so that it flows down in a continuous column.
[0038] A remote control 4 (operating unit) for the faucet device 1 is attached to a wall portion 1004b of the bathroom unit 1000. The remote control 4 may be attached to the wall portion 1004a on which the first counter 1002 and the second counter 1003 are attached.
[0039] The remote control 4 accepts various operations by the user on the faucet main body 3. Specifically, the remote control 4 accepts operations to set the hot and cold water temperature in the faucet main body 3. The remote control 4 accepts operations to set the hot and cold water flow rate in the faucet main body 3. The remote control 4 accepts operations to switch between discharging and stopping hot and cold water. The remote control 4 accepts operations to switch the destination to which hot and cold water is discharged. When operated by the user, the remote control 4 sends an operation signal corresponding to each operation to the controller 7 of the faucet device 1 (see Figure 3).
[0040] 2, the remote control 4 includes a temperature adjustment button 41, a water volume adjustment button 42, and a switching button 43. FIG. 2 is a front view showing the remote control 4.
[0041] The temperature adjustment button 41 is a button for adjusting the temperature of the mixed water in the faucet body 3. The temperature adjustment button 41 includes a high temperature button 41a and a low temperature button 41b. The high temperature button 41a is a button for increasing the temperature of the mixed water. The low temperature button 41b is a button for decreasing the temperature of the mixed water. The remote control 4 displays the set temperature of the mixed water on the first display unit 45a. When the high temperature button 41a or the low temperature button 41b is operated, the display on the first display unit 45a changes in accordance with the operation of each button 41a, 41b.
[0042] The temperature of the mixed water in the faucet body 3 can be adjusted within a predetermined temperature range. When the low temperature button 41b is operated and the set temperature of the mixed water becomes lower than the lowest temperature in the predetermined temperature range, the faucet body 3 does not mix hot water with cold water and instead dispenses cold water.
[0043] The water volume adjustment button 42 is a button for adjusting the flow rate of hot and cold water dispensed from the faucet device 1. The water volume adjustment button 42 includes an increase water button 42a and a decrease water button 42b. The increase water button 42a is a button for increasing the flow rate of hot and cold water. The decrease water button 42b is a button for decreasing the flow rate of hot and cold water. The remote control 4 displays the set status of the hot and cold water volume on the second display unit 45b. When the increase water button 42a or the decrease water button 42b is operated, the display on the second display unit 45b changes in accordance with the operation of each button 42a, 42b. The flow rate of hot and cold water dispensed from the faucet device 1 can be adjusted within a predetermined flow rate range.
[0044] The switching button 43 is a button for switching between discharging hot and cold water and stopping the water supply in the faucet device 1. The switching button 43 is also a button for switching the destination of the hot and cold water supply in the faucet device 1. The switching buttons 43 include a faucet button 43a, a hand shower button 43b, an overhead shower button 43c, and a warm pillar button 43d. Each of the buttons 43a to 43d is switched between "ON" and "OFF" when pressed by the user.
[0045] When each of the buttons 43a to 43d of the switching button 43 is set to "OFF," hot or cold water is not discharged. In other words, the water faucet device 1 is in a water stop state.
[0046] When any one of the switching buttons 43, 43a to 43d, is pressed from the "OFF" state, and the pressed switching button 43 becomes "ON," hot or cold water is discharged. In other words, the water faucet device 1 changes from a water stop state to a water discharge state.
[0047] When one of the switching buttons 43 is "ON" and another switching button 43 is pressed, the switching button 43 that is "ON" is changed, and the destination of hot and cold water is switched.
[0048] For example, when hand shower button 43b is "ON," hot and cold water is discharged from hand shower 11. When faucet button 43a is pressed in this state, hand shower button 43b turns "OFF" and faucet button 43a turns "ON." This changes the destination of hot and cold water discharge from hand shower 11 to faucet 10, and hot and cold water is discharged from faucet 10.
[0049] When the "ON" switch button 43 is pressed again, the pressed switch button 43 turns "OFF," and each of the buttons 43a to 43d of the switch button 43 turns "OFF," stopping the flow of hot and cold water. In other words, the water faucet device 1 changes from a water discharge state to a water stop state.
[0050] Each of the buttons 43a to 43d is configured so that the user can distinguish between the "ON" and "OFF" states. For example, a switching button 43 that is "ON" lights up, and a switching button 43 that is "OFF" lights up.
[0051] Although the faucet device 1 capable of discharging hot and cold water from the overhead shower 12, warm pillar 13, hand shower 11, and faucet 10 has been described as an example, the present invention is not limited to this. For example, the faucet device 1 may be configured without the overhead shower 12 and warm pillar 13.
[0052] Next, an overview of the faucet device 1 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a block diagram showing an overview of the faucet device 1 according to the embodiment. In Fig. 3, the flow of hot and cold water is indicated by solid arrows, and communication lines are indicated by dashed lines.
[0053] The faucet device 1 comprises a plurality of water discharge units 2, a faucet body 3, a remote control 4, and a communication unit 5.
[0054] The plurality of water discharge units 2 include a faucet 10, a hand shower 11, an overhead shower 12, and a warm pillar 13.
[0055] The faucet body 3 includes a mixer faucet unit 20, a water discharge switching section 30, and a controller 7.
[0056] The mixing faucet unit 20 includes a hot and cold water mixing section 50 and a flow rate adjustment section 60. Hot water is supplied to the hot and cold water mixing section 50 from a hot water supply source 80. In addition, water is supplied to the hot and cold water mixing section 50 from a water supply source 81. A stop valve 84 is provided in the flow path (hot water supply pipe 82) between the hot and cold water mixing section 50 and the hot water supply source 80. In addition, a stop valve 85 is provided in the flow path (water supply pipe 83) between the hot and cold water mixing section 50 and the water supply source 81.
[0057] The hot and cold 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 hot and cold water mixing unit 50 switches whether or not to mix hot water with cold water. The hot and cold water mixing unit 50 also adjusts the ratio of hot water to be mixed with cold water, thereby adjusting the temperature of the mixed water.
[0058] The hot and cold water mixing unit 50 includes a motor 51. The motor 51 is, for example, a stepping motor. When the temperature adjustment button 41 on the remote control 4 is operated, the hot and cold water mixing unit 50 drives the temperature control valve 210 (see FIG. 7) to switch whether or not to mix hot water with cold water.
[0059] Furthermore, in response to operation of the temperature adjustment button 41 on the remote control 4, the hot and cold water mixing unit 50 drives the temperature control valve 210 by driving the motor 51, thereby adjusting the ratio of hot water to be mixed with water. Furthermore, even if the temperature adjustment button 41 is not operated, for example, when the temperature of the hot water changes and the temperature of the mixed water changes, the hot and cold 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 water according to the temperature of the mixed water.
[0060] Hot and cold water flows into the flow rate adjusting unit 60 from the hot and cold water mixing unit 50. When hot and cold water is discharged from the water discharge unit 2, the flow rate adjusting unit 60 adjusts the flow rate of the discharged hot and cold water.
[0061] The flow rate adjustment unit 60 includes a motor 61. The motor 61 is, for example, a stepping motor. In response to operation of the water volume adjustment button 42 on the remote control 4, the motor 61 is driven to drive the flow regulation valve 230 (see FIG. 7), thereby adjusting the flow rate of hot and cold water.
[0062] The water discharge switching unit 30 switches between discharging and stopping hot and cold water flowing out from the mixer faucet unit 20. In other words, the water discharge switching unit 30 switches between discharging and stopping hot and cold water from the water discharge unit 2. The water discharge switching unit 30 also switches the destination to which the hot and cold water is discharged. The faucet device 1 switches between discharging and stopping hot and cold water from the water discharge unit 2 using the water discharge switching unit 30, and adjusts the flow rate of the hot and cold water when it is being discharged using the flow rate adjustment unit 60.
[0063] The water discharge switching unit 30 includes a plurality of solenoid valves 31 to 35. Specifically, the water discharge switching unit 30 includes a first solenoid valve 31, a second solenoid valve 32, a third solenoid valve 33, and a fourth solenoid valve 34. The water discharge switching unit 30 may also include a fifth solenoid valve 35.
[0064] The first solenoid valve 31 to the fourth solenoid valve 34 are switched to "closed (OFF)" or "open (ON)" in response to the operation of the switching button 43.
[0065] When the first solenoid valve 31 to the fourth solenoid valve 34 are "closed," hot or cold water is not discharged from the water discharge section 2. In other words, when the first solenoid valve 31 to the fourth solenoid valve 34 are "closed," hot or cold water is stopped. When any one of the first solenoid valve 31 to the fourth solenoid valve 34 is "open," hot or cold water is discharged from the water discharge section 2 corresponding to the solenoid valve that is "open."
[0066] The first solenoid valve 31 switches between discharging and stopping hot and cold water at the faucet 10. The second solenoid valve 32 switches between discharging and stopping hot and cold water at the hand shower 11. The third solenoid valve 33 switches between discharging and stopping hot and cold water at the overhead shower 12. The fourth solenoid valve 34 switches between discharging and stopping hot and cold water at the warm pillar 13.
[0067] For example, when the first solenoid valve 31 is "open" and the second solenoid valve 32 to the fourth solenoid valve are "closed", hot and cold water is discharged from the faucet .
[0068] The fifth solenoid valve 35 is switched to "closed (OFF)" or "open (ON)" in response to operation by an external device 89 (for example, a multi-remote control provided in the bathroom). The fifth solenoid valve 35 may also be switched to "closed" or "open" in response to operation by the remote control 4. The fifth solenoid valve 35 is a valve for discharging residual water from the hose of the hand shower 11 or the like and from the piping, and is normally kept "closed." In other words, the fifth solenoid valve 35 is "open" only when residual water treatment is performed. When the fifth solenoid valve 35 is "open," residual water is discharged from the residual water discharge flow path 88.
[0069] The controller 7 controls the motor 51, the motor 61, and the first solenoid valve 31 to the fourth solenoid valve 34 in response to the operation of the faucet body 3 received by operating the remote control 4. The controller 7 also controls the fifth solenoid valve 35 in response to the operation of an external device 89, for example.
[0070] The controller 7 includes various circuits and a microcomputer having, for example, a central processing unit (CPU), read-only memory (ROM), random access memory (RAM), etc. The controller 7 may also include hardware such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).
[0071] The communication unit 5 receives operation signals from the remote control 4 and the external device 89, and transmits the received operation signals to the controller 7. The remote control 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.
[0072] Next, the faucet body 3 will be described with reference to Figure 4. Figure 4 is a perspective view showing the faucet body 3. In addition to the mixer faucet unit 20, the water discharge switching unit 30, and the controller 7 (see Figure 3), the faucet body 3 comprises a flow path unit 70. The faucet body 3 is attached to the wall 1004a (see Figure 1) of the bathroom unit 1000 by the flow path unit 70.
[0073] The flow path unit 70 is formed with a flow path that allows hot water supplied from a hot water supply source 80 (see Figure 3) to flow into the mixer tap unit 20, a flow path that allows water supplied from a water supply source 81 (see Figure 3) to flow into the mixer tap unit 20, and a flow path that allows hot and cold water to flow from the mixer tap unit 20 to each water discharge section 2. The flow path unit 70 is also provided with a water discharge switching section 30. The flow path unit 70 is also provided with stop valves 84, 85 (see Figure 3). The flow path unit 70 is also provided with a residual water discharge flow path 88.
[0074] In the faucet body 3, a flow path unit 70 is provided at the rear, and a mixer faucet unit 20 is provided in front of the flow path unit 70. A part of the flow path unit 70 is provided above the mixer faucet unit 20. Also, a controller case 201 that houses the controller 7 is provided in front of the mixer faucet unit 20.
[0075] Next, the mixer tap unit 20 will be described with reference to Figures 5 to 7. Figure 5 is a perspective view showing the mixer tap unit 20. Figure 6 is a front view showing the mixer tap unit 20. Figure 7 is a perspective view of the VII-VII cross section of Figure 6.
[0076] The mixer faucet unit 20 is installed to extend in the left-right direction. A motor case 200a that houses the motor 51 of the hot and cold water mixing section 50 is installed at one left-right end of the mixer faucet unit 20, specifically the left end. A motor case 200b that houses the motor 61 of the flow rate adjustment section 60 is installed at the other left-right end of the mixer faucet unit 20, specifically the right end.
[0077] The hot and cold water mixing unit 50 switches whether or not to mix the hot water supplied from the hot water supply channel 203 with the water supplied from the water supply channel 202 by moving the temperature adjustment valve 210 (adjustment valve) in the left-right direction.
[0078] For example, when the temperature control valve 210 abuts against the case 211 provided to the left of the temperature control valve 210, the supply of hot water is blocked by the temperature control valve 210, and the hot water is not mixed with the water supplied from the water supply path 202.
[0079] Furthermore, by separating the temperature control valve 210 from the case 211, the supply of hot water is not blocked by the temperature control valve 210, and the hot water supplied from the hot water supply path 203 is mixed with the water supplied from the water supply path 202.
[0080] The temperature control valve 210 is biased by the temperature sensitive spring 212 in a direction away from the case 211. The temperature control valve 210 is also biased by the bias spring 213 in a direction toward contact with the case 211. That is, the temperature control valve 210 moves left and right depending on the magnitude relationship between the biasing force of the temperature sensitive spring 212 and the biasing force of the bias spring 213.
[0081] The temperature-sensitive spring 212 is a spring whose spring constant changes depending on the temperature, and is made of, for example, a shape memory alloy. The bias spring 213 is a spring whose spring constant is almost constant regardless of the temperature.
[0082] When the biasing force of the bias spring 213 is greater than the biasing force of the temperature-sensing spring 212, the temperature control valve 210 moves leftward toward the case 211. When the temperature control valve 210 is in contact with the case 211, the temperature control valve 210 is maintained in contact with the case 211.
[0083] When the biasing force of the temperature-sensing spring 212 is greater than the biasing force of the bias spring 213, the temperature adjustment valve 210 moves to the right so as to move away from the case 211.
[0084] When the biasing force of the temperature sensitive spring 212 and the biasing force of the bias spring 213 are equal, the temperature adjustment valve 210 does not move left or right and is held in a position where the biasing force of the temperature sensitive spring 212 and the biasing force of the bias spring 213 are balanced.
[0085] The temperature-sensing spring 212 abuts against the liner 214 at one end opposite to the end that abuts against the temperature control valve 210. The liner 214 is connected to a rotating shaft 216 via a spindle 215. The spindle 215 is rotatably supported by the case 211, and converts the rotational movement of the rotating shaft 216 into linear movement of the liner 214 in the left-right direction. Therefore, the liner 214 moves left-right in response to the rotation of the rotating shaft 216.
[0086] 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 rotation of the rotating shaft of the motor 51 is transmitted to the rotating shaft 216 by the transmission mechanism. The transmission mechanism is the same as the transmission mechanism in the flow rate adjustment unit 60, which will be described later.
[0087] In the hot and cold water mixing unit 50, the liner 214 moves left and right in accordance with the rotational position of the rotating shaft 216, i.e., in accordance with the rotational position of the rotating shaft of the motor 51. That is, the hot and cold water mixing unit 50 can change the position of the temperature control valve 210 to a position where the biasing force of the temperature sensing spring 212 and the biasing force of the bias spring 213 are balanced in accordance with the rotational position of the rotating shaft of the motor 51. As a result, when discharging mixed water, the hot and cold water mixing unit 50 can set the temperature of the mixed water to a set temperature that corresponds to the rotational position of the rotating shaft of the motor 51.
[0088] Furthermore, when discharging mixed water, if the temperature of the hot water changes and the temperature of the mixed water changes, for example, the temperature-sensitive spring 212 expands and contracts according to the temperature of the mixed water, and the temperature control valve 210 moves left and right, automatically changing the equilibrium position of the temperature control valve 210. This adjusts the amounts of hot and cold water in the mixed water, and automatically adjusts the temperature of the mixed water.
[0089] The hot and cold water mixer 50 is in communication with the flow rate adjuster 60 via a communication hole 220. Hot and cold water flows into the flow rate adjuster 60 from the hot and cold water mixer 50 via the communication hole 220.
[0090] The flow rate adjustment unit 60 rotates the flow rate adjustment valve 230 (adjustment valve) around 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 rate adjustment valve 230, and changing the opening degree of the flow rate adjustment valve 230. By changing the opening degree of the flow rate adjustment valve 230, the flow rate adjustment unit 60 adjusts the flow rate of hot and cold water flowing out of the mixer faucet unit 20, i.e., the flow rate of hot and cold water discharged from the water discharge unit 2 (see Figure 3).
[0091] Next, the faucet body 3 will be further described with reference to Figures 8 and 9. Figure 8 is an explanatory diagram of the connection of the faucet body 3. Figure 9 is a perspective view of the faucet body 3. Figure 9 shows the faucet body 3 as seen from the rear.
[0092] As shown in FIG. 8, the faucet body 3 is attached to the wall W of the bathroom unit 1000 (see FIG. 1). B The faucet body 3 supplies hot and cold water to a plurality of water outlets 2 (see FIG. 3) including a faucet 10 (see FIG. 3), a hand shower 11 (see FIG. 3), an overhead shower 12 (see FIG. 3), and a warm pillar 13 (see FIG. 3).
[0093] The faucet body 3 is the wall W of the bathroom unit 1000. B The connecting member 90 comprises a hot water supply member 91, a water supply member 92, and a hot water outlet member 93. Of these, the hot water outlet member 93 is connected to a hot water outlet pipe 94 arranged outside the bathroom unit. There are multiple hot water outlet pipes 94, and each connects multiple water discharge units 2 to the faucet body 3.
[0094] As shown in Figure 8, the faucet body 3 includes a hot water supply connection portion 110, a water supply connection portion 111, a first water discharge connection portion 112, a second water discharge connection portion 113, a third water discharge connection portion 114, and a fourth water discharge connection portion 115. The hot water supply connection portion 110 is connected to the hot water supply member 91. The water supply connection portion 111 is connected to the water supply member 92. The first water discharge connection portion 112, the second water discharge connection portion 113, the third water discharge connection portion 114, and the fourth water discharge connection portion 115 are each connected to the hot water outlet member 93.
[0095] Hot water connection 110, water supply connection 111, first water discharge connection 112, second water discharge connection 113, third water discharge connection 114 and fourth water discharge connection 115 are formed in flow path unit 70. As described above, flow path unit 70 is provided with a flow path that allows hot water supplied from hot water source 80 (see Figure 3) to flow into mixer tap unit 20 (see Figure 4), a flow path that allows water supplied from water supply source 81 (see Figure 3) to flow into mixer tap unit 20, and flow paths that allow hot and cold water to flow from mixer tap unit 20 to each water discharge unit 2.
[0096] The flow path unit 70 also includes a water discharge switching section 30 (see FIG. 4), stop valves 84 and 85 (see FIG. 3), and a residual water discharge flow path 88 (see FIG. 4). B When the connecting member 90 is attached to the passage unit 70, the rod portion 95 provided on the connecting member 90 is inserted into a cylindrical receiving portion 116 provided on the rear surface of the passage unit 70, thereby positioning the passage unit 70.
[0097] 9, in the faucet body 3, at least one of the hot water supply connection part 110, the water supply connection part 111, the first water discharge connection part 112, and the second water discharge connection part 113 is movable in the connection axis direction AX. In addition, in the faucet body 3, at least one of the hot water supply connection part 110, the water supply connection part 111, the first water discharge connection part 112, the second water discharge connection part 113, the third water discharge connection part 114, and the fourth water discharge connection part 115 is movable in the connection axis direction AX.
[0098] Furthermore, in the faucet body 3, movement in the connection axis direction AX of any three 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 is restricted. In the faucet body 3, the remaining connection parts are movable in the connection axis direction AX.
[0099] 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, the connection part that can move in the connection axis direction AX has a movable part 400, which will be described later. The movable part 400 has a bush 420 (see FIG. 11), which will be described later, whose insertion length with respect to the faucet body 3 is adjustable.
[0100] Furthermore, movement of the hot water supply connection part 110 and the cold water supply connection part 111 in the faucet body 3 in the connection axial direction AX is restricted. The hot water supply connection part 110 and the cold water supply connection part 111 are provided with a fixing part 300, which will be described later.
[0101] 9, 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 in a virtual triangle T on a virtual plane formed by three points (P1 to P3) of the three connection parts whose movement in the connection axis direction AX is restricted. V is placed outside.
[0102] With this configuration, at least one of hot water supply connection 110, cold water supply connection 111, first water discharge connection 112, and second water discharge connection 113 is movable in the connection axis direction AX, making it possible to adjust the position in the connection axis direction AX of components such as hot water outlet member 93 (see Figure 8) connected to a connection part that is movable in the connection axis direction AX. This makes it possible to absorb errors in the connection axis direction AX when connecting faucet body 3, which serves as a functional part, to piping such as hot water outlet pipe 94 (see Figure 8) located outside bathroom unit 1000 (see Figure 1), thereby reducing installation defects and improving installation efficiency.
[0103] In addition, a virtual triangle T is formed by three points (P1 to P3) of three connection parts whose movement in the connection axis direction AX is restricted. V This makes it possible to adjust the position of the connection axis direction AX of the remaining connection parts, and all connection parts can be positioned on the same plane, so that errors in the connection axis direction AX when connecting the faucet body 3, which is the functional part, to piping such as the hot water outlet pipe 94 located outside the bathroom unit 1000 can be effectively absorbed, preventing poor installation and reducing the number of places where position adjustment is required compared to when all connection parts are movable, thereby improving installation efficiency.
[0104] Furthermore, in a connection portion that is movable in the direction of the connection axis AX, an error in the direction of the connection axis AX can be absorbed by a simple configuration in which the insertion margin of the bush 420 (see FIG. 11) is adjusted.
[0105] Furthermore, the hot water supply connection 110 and the cold water supply connection 111 are primary side connection parts, which are the water supply side with high water pressure. Therefore, by restricting movement of the primary side connection parts in the connection axis direction AX, the primary side can be firmly connected and fixed, and the connection reliability of the primary side can be improved.
[0106] Furthermore, by adjusting the connection part that is movable in the direction of the connection axis AX after the connection part that is restricted from moving in the direction of the connection axis AX has been fixed, the adjustment of the connection part that is movable in the direction of the connection axis AX becomes easy. This makes it possible to prevent installation defects and improve installation efficiency.
[0107] Furthermore, the third water discharge connection part 114 and the fourth water discharge connection part 115 are movable in the connection axis direction AX. As shown in Fig. 9, the third water discharge connection part 114 and the fourth water discharge connection part 115 are arranged within 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 This makes it possible to prevent installation defects and improve installation efficiency even when the number of connection parts that can move in the connection axis direction AX increases.
[0108] In the faucet body 3, 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 may all be movable in the connection axis direction AX.
[0109] With this configuration, the position of the connection axis direction AX can be adjusted at each of the four connection parts, so that errors in the connection axis direction AX can be absorbed when connecting the faucet body 3, which is the functional part, to piping such as the hot water outlet pipe 94 located outside the bathroom unit 1000, thereby reducing installation defects and improving installation efficiency.
[0110] Furthermore, faucet body 3 is positioned below counters (first counter 1002 and second counter 1003) (see Figure 1) located inside bathroom unit 1000 (see Figure 1). In faucet body 3, the connections that can move in the connection axis direction AX among hot water supply connection 110, water supply connection 111, first water discharge connection 112 and second water discharge connection 113 are secondary side connections on the water discharge side, and are positioned above primary side water supply connection 111 and hot water supply connection 110 on the water supply side.
[0111] This configuration makes it easy to adjust the position of the connecting portion that is movable in the connection axial direction AX, thereby reducing installation defects and improving installation efficiency.
[0112] Next, the fixed part 300 and the movable part 400 of the faucet body 3 will be described with reference to Figures 10 and 11. Figure 10 is a side cross-sectional view showing the fixed part 300. Figure 10 is a side cross-sectional view showing the movable part 400.
[0113] The fixing part 300 provides a fixing structure for restricting movement of the faucet body 3 (see FIG. 9) in the connection axis direction AX. As shown in FIG. 10, the fixing part 300 is provided on one of the connection parts (for example, the hot water supply connection part 110). The fixing part 300 includes a cap nut 310, a bushing 320, sealing members 330 and 340, and the abutment part 110a of the hot water supply connection part 110.
[0114] The cap nut 310 is formed in a cylindrical shape and is attached to one end (base end) of the bushing 320 so as to cover the one end from the connection axial direction AX.
[0115] The bushing 320 is formed in a cylindrical shape. The bushing 320 includes a flange portion 321 and a retaining portion 322. The flange portion 321 is provided at one end of the bushing 320. The flange portion 321 is provided so as to extend outward from the outer circumferential surface of the bushing 320. The retaining portion 322 is provided on the outer circumferential surface of the bushing 320. The retaining portion 322 is a recess that extends circumferentially along the outer circumferential surface of the bushing 320.
[0116] The seal member 330 is formed in an annular shape. The seal member 330 is held by the holder 322 and is held between the outer circumferential surface of the bushing 320, which forms the sealing surface, and the inner circumferential surface of the hot water supply connection part 110. The seal member 340 is formed in an annular shape. The seal member 340 is held on the end face (base end face) of one end (base end) of the bushing 320.
[0117] The contact portion 110a of the hot water supply connection portion 110 is formed in a stepped shape on the inner surface of the hot water supply connection portion 110. The end face (tip face) of the other end (tip portion) of the bushing 320 contacts the contact portion 110a, thereby restricting movement of the bushing 320 in the connection axial direction AX.
[0118] The movable part 400 provides a movable structure that enables movement in the connection axis direction AX of the faucet body 3 (see FIG. 9). As shown in FIG. 11, the movable part 400 is provided on one of the connection parts (for example, the first water discharge connection part 112). The movable part 400 includes a cap nut 410, a bushing 420, sealing members 430, 440, and the connection part-side thread part 112a of the first water discharge connection part 112.
[0119] The cap nut 410 is formed in a cylindrical shape and is attached to one end (base end) of the bushing 420 so as to cover the one end from the connection axial direction AX.
[0120] The bushing 320 is formed in a cylindrical shape. The bushing 420 includes a flange portion 421, a retaining portion 422, a threaded portion 423, and a middle portion 424. The flange portion 421 is provided at one end of the bushing 420. The flange portion 421 is provided so as to extend outward from the outer circumferential surface of the bushing 420. The retaining portion 422 is provided on the outer circumferential surface of the bushing 420. The retaining portion 422 is a recess that extends circumferentially on the outer circumferential surface of the bushing 420.
[0121] The threaded portion 423 is formed at the other end (tip) of the bushing 420. The midway portion 424 is formed on the outer peripheral surface of the bushing 420, and is formed at a position closer to one end of the bushing 420 than the threaded portion 423. At the midway portion 424, the diameter of the bushing 420 is smaller, and a space is formed between the midway portion 424 and the inner surface of the first water discharge connection portion 112.
[0122] The sealing member 430 is formed in an annular shape. The sealing member 430 is held by the holding portion 422, and is held between the outer peripheral surface of the bushing 420, which forms the sealing surface, and the inner peripheral surface of the first water discharge connection portion 112. In this case, because it is an axial seal, the watertightness of the faucet body 3 and the bushing 420 can be easily ensured even if the insertion allowance of the bushing 420 is adjusted, compared to when a surface seal sealing member that ensures sealing performance by a crushing allowance in the connection axis direction AX is held on the faucet body 3 side.
[0123] The seal member 440 is formed in an annular shape and is held on the end face (base end face) of one end (base end) of the bushing 420.
[0124] The threaded portion 423 of the bushing 420 screws into the connection portion side threaded portion 112a formed near the seal surface of the first water discharge connection portion 112. As the threaded portion 423 becomes more engaged with the connection portion side threaded portion 112a, it passes through this connection portion side threaded portion 112a. In this case, the connection portion side threaded portion 112a is held in place by the intermediate portion 424. As a result, the bushing 420 is prevented from coming off at the other end by the threaded portion 423, and can move in the connection axial direction AX by the length of the intermediate portion 424 along the connection axial direction AX.
[0125] According to this configuration, the threaded portion 423 and the intermediate portion 424 of the bushing 420 form a retaining structure for the bushing 420. In this retaining structure, the threaded portion 423, which has threadedly passed through the connection portion-side threaded portion 112a, is prevented by the connection portion-side threaded portion 112a from coming off in the connection axial direction AX, thereby preventing the bushing 420 from coming off or falling off during installation, significantly improving installation efficiency. Furthermore, the intermediate portion 424 can hold the connection portion-side threaded portion 112a so that it can move in the connection axial direction AX.
[0126] The movable part 400 has a clearance 450 between the inner surface of the cap nut 410 and the outer surface of the bushing 420. A face seal is formed between the bushing 420 and a member such as the tapping member 93 (see FIG. 8) connected via the bushing 420.
[0127] This configuration can absorb radial errors in the bushing 420 of the movable part 400 while maintaining watertightness in the hot water supply connection part 100, the cold water supply connection part 101, the first water discharge connection part 102, and the second water discharge connection part 103. This can reduce installation defects and improve installation efficiency.
