When detergent is dispensed from the bathtub cleaning unit 40, the detergent adheres to the inner wall of the bathtub 8. The bathtub cleaning unit 40 cleans the inner wall of the bathtub 8, for example, by alternately dispensing water and detergent.

[0018] The bathroom water outlet 20 is disposed in the bathroom. The kitchen water outlet 22 is disposed in the kitchen. The kitchen water outlet 22 is equipped with a water purifier (not shown). The bathroom 2, the bathroom, and the kitchen are disposed within the building 200.

[0019] (Configuration of motor-operated valve) Motor-operated valve 9 is disposed between the hot water supply source, the cold water supply source, and water discharge portion 202. Motor-operated valve 9 adjusts the temperature and flow rate of water supplied to water discharge portion 202 by adjusting the opening of supply pipes that connect the hot water supply source and the cold water supply source to water discharge portion 202. Motor-operated valve 9 also switches the destination of the adjusted water. The destination of the water is water discharge portion 202. Specifically, motor-operated valve 9 can supply water at a first temperature and a first flow rate to hand shower portion 30 of bathroom water discharge portion 18, for example. In another example, motor-operated valve 9 can supply water at a second temperature that is higher than the first temperature and at a second flow rate that is lower than the first flow rate to washroom water discharge portion 20. Motor-operated valve 9 is composed of multiple motor-operated valves.

[0020] (Configuration of faucet control device) The faucet control device 10 is placed outside the bathroom 2. The faucet control device 10 is a device for controlling the motor-operated valve 9. The faucet control device 10 comprises a communication interface 60, a CPU 62, and a memory 64. Hereinafter, the interface will be referred to as "I / F."

[0021] The communication I / F 60 includes a wired I / F and a wireless I / F. The faucet control device 10 is wiredly connected to the bathroom water spout 18, the washroom water spout 20, and the kitchen water spout 22 via the wired I / F. The faucet control device 10 can control the operation of each of these elements 18, 20, and 22. The faucet control device 10 is further wiredly connected to the faucet remote control 12 and a lighting control device 162 (described later) via the wired I / F. The faucet control device 10 can communicate with each of these elements 12 and 162 via the communication I / F 60. The faucet control device 10 is further wirelessly connected to the gateway device 14 via the wireless I / F. The faucet control device 10 can communicate with the gateway device 14 via the wireless I / F. In a modified example, the communication I / F 60 may be a wired I / F. In another modified example, the communication I / F 60 may be a wireless I / F.

[0022] The CPU 62 executes processing in accordance with various programs stored in the memory 64. The CPU 62 is electrically connected to the communication I / F 60 and the memory 64, and can control the operation of each of these elements. The memory 64 is composed of a ROM, a RAM, a flash memory, etc.

[0023] As shown in Fig. 1, the memory 64 stores a faucet management table 108. As shown in Fig. 11, the faucet management table 108 stores filter information and detergent information in association with each other.

[0024] The filter information is information about the filter attached to the water purifier of the kitchen water discharge portion 22. Specifically, the filter information includes a flow rate threshold Th1 and a total flow rate FL1 of the kitchen water discharge portion 22. The faucet control device 10 records the total flow rate FL1 of the kitchen water discharge portion 22 in memory 64. When the total flow rate FL1 exceeds the flow rate threshold Th1, the faucet control device 10 can detect that it is time to replace the filter attached to the water purifier of the kitchen water discharge portion 22.

[0025] In a modified example, the filter information may include a resistance threshold value Th2 and a filter resistance value R1. In this case, the faucet control device 10 obtains the filter resistance value R1 using a known method and stores it in memory 64. When the filter resistance value R1 exceeds the resistance threshold value Th2, the faucet control device 10 can detect that it is time to replace the filter attached to the water purifier of the kitchen water discharge portion 22. The time to replace the filter corresponds to the "time to replace consumables."

[0026] The flow rate threshold Th1 and the resistance threshold Th2 may be arbitrarily set by the user, or may be set to predetermined values.

[0027] The detergent information is information relating to the time to replenish the liquid detergent in the foam supply device 55. Specifically, the detergent information includes a flow rate threshold Th3 and a total flow rate FL2 of the foam discharged from the shower head 50. The faucet control device 10 stores the total flow rate FL2 of the foam discharged from the foam supply device 55, and can detect that it is time to replenish the liquid detergent in the foam supply device 55 when the total flow rate FL2 exceeds the flow rate threshold Th3.

[0028] In a variant, the detergent information may include the remaining amount of detergent. The foam supply device 55 is equipped with a sensor for detecting the remaining amount of liquid detergent. The sensor may be, for example, a water level detection sensor, a weight sensor, etc. The remaining amount of detergent is detected by the sensor. When the remaining amount of detergent falls below a predetermined threshold, the faucet control device 10 can detect that it is time to refill the liquid detergent in the foam supply device 55. The time to refill the liquid detergent corresponds to the "time to replace consumables."

[0029] (Configuration of faucet remote control) 2 and 3, the faucet remote control 12 is placed on the wall surface 4. The faucet remote control 12 is attached to the wall surface 4 by, for example, a magnet or a suction cup. In a modified example, the faucet remote control 12 may be placed on a shelf (not shown) in the bathroom 2. As shown in FIG. 4, the faucet remote control 12 includes a communication I / F 66, a CPU 68, a memory 70, an operation unit 72, a display unit 74, a power supply source 76, a speaker 78, a microphone 79, a vibration unit 80, a light-emitting unit 82, an infrared sensor 84, a gesture sensor 86, a temperature and humidity sensor 88, and a human body detection sensor 90.

[0030] The communication I / F 66 is connected to the communication I / F 60 of the faucet control device 10. The communication I / F 66 may be a wireless I / F or a wired I / F. When the communication I / F 66 is a wireless I / F, the faucet remote control 12 does not require wiring for communication. This allows the user to operate the faucet remote control 12 wirelessly, which is more convenient than when a wired I / F is used.

[0031] The CPU 68 executes processing in accordance with various programs stored in the memory 70. The CPU 68 is electrically connected to the communication I / F 66, the memory 70, the operation unit 72, the display unit 74, the power supply source 76, the speaker 78, the microphone 79, the vibration unit 80, the light-emitting unit 82, the infrared sensor 84, the gesture sensor 86, the temperature and humidity sensor 88, and the human body detection sensor 90, and can control the operation of each of these elements. The memory 70 is composed of a ROM, a RAM, a flash memory, etc.

[0032] The memory 70 stores a user table 106. As shown in Fig. 11, the user table 106 is a table for managing information related to users (i.e., user information). The user table 106 stores a user name (e.g., "U1") for identifying a user, a date of birth (e.g., "BD1"), health information, water discharge information, customization setting information, and location information in association with each other.

[0033] The health information includes height (eg, "T1"), weight (eg, "W1"), body fat percentage (eg, "F1"), body temperature (eg, "Tm1"), and blood pressure (eg, "P1").

[0034] The water discharge information is information related to the water discharge the user last time. The water discharge information includes the water discharge unit (e.g., "hand shower unit"), temperature (e.g., "40°C"), and flow rate (e.g., "2").

The first setting information includes a first pattern and a second pattern. The first pattern includes a combination of a hand shower unit, 40°C, and a flow rate of 3. The second pattern includes a combination of an overhead shower unit, 45°C, and a flow rate of 5. In combinations of flow rate and a number, such as "flow rate 3" and "flow rate 5," the number indicates the level of flow rate. The maximum flow rate that can be discharged is "5," and the flow rate is specified in five levels from 1 to 5. Flow rate 5 is the highest, and flow rate 1 is the lowest.

[0036] The location information indicates the location information (for example, "L1") of a predetermined terminal device (for example, communication terminal 130) of the user.

[0037] The user name, date of birth, health information, water discharge information, and customization setting information are acquired by the operation unit 72 of the faucet remote control 12. Specifically, the user inputs the user name, date of birth, health information, water discharge information, and customization setting information by operating the operation unit 72 of the faucet remote control 12. The location information is stored in the user table 106 in response to the location information of the terminal device itself being transmitted from a specific terminal device of the user to the faucet control device 10.

[0038] In a modified example, the user name, date of birth, health information, water discharge information, and customization setting information may be acquired by the user from a predetermined terminal device (e.g., communication terminal 130). Specifically, the user inputs the user name, date of birth, health information, water discharge information, and customization setting information by operating the predetermined terminal device. The predetermined terminal device transmits the input information to the faucet control device 10. The faucet control device 10 stores the received information in the user table 106.

[0039] In another variation, the health information, including height, weight, and body fat percentage, may be acquired from a terminal device capable of acquiring the user's health information, such as a body composition meter (not shown). Specifically, the body composition meter transmits information including the user's height, weight, and body fat percentage acquired by the user measuring with the body composition meter to the faucet control device 10. The faucet control device 10 stores the received information in the user table 106.

[0040] In another variation, the health information, including height, weight, body fat percentage, body temperature, and blood pressure, may be obtained from a predetermined server. The predetermined server is connected to the Internet 15. The height, weight, body fat percentage, body temperature, and blood pressure are stored in the predetermined server so that the user can use the services provided by the predetermined server. The faucet control device 10 receives information including the user's height, weight, body fat percentage, body temperature, and blood pressure from the predetermined server via the Internet 15. The received user's height, weight, body fat percentage, body temperature, and blood pressure are then stored in the user table 106.

[0041] As shown in FIG. 5, the operation unit 72 includes a plurality of buttons 72a and a rotary operation unit 72b. When operated by a user, the operation unit 72 accepts instructions corresponding to the operation. By operating the operation unit 72, the user can input various instructions related to the water discharger 202 into the faucet remote control 12. The operation unit 72 can also be used to activate or deactivate a child lock function. For example, the user can activate or deactivate the child lock function by simultaneously pressing and holding two of the plurality of buttons 72a.

[0042] The display unit 74 is a display for displaying various information. The display unit 74 may be a liquid crystal display. In this embodiment, the display unit 74 does not function as a so-called touch panel (that is, an operation unit).

[0043] The power supply source 76 supplies power to the faucet remote control 12. The power supply source 76 is a primary battery. In a modified example, the power supply source 76 may be a secondary battery. In another modified example, the power supply source 76 may be a terminal for wirelessly supplying power output from a known household power source (or commercial power source) to the faucet remote control 12 via a wireless power supply device. The wireless power supply device can also supply power to terminal devices other than the faucet remote control 12, such as smartphones. Therefore, a user can power (i.e., charge) a terminal device by installing the terminal device in the wireless power supply device instead of the faucet remote control 12. The wireless power supply device may be installed on the wall 4, on the edge of the bathtub 8, or on a shelf (not shown) in the bathroom 2. With this configuration, the faucet remote control 12 does not require wiring for power supply. This allows the user to use the faucet remote control 12 wirelessly.

[0044] In yet another modified example, the power supply source 76 may be a terminal for supplying power output from a known household power source (or commercial power source) to the faucet remote control 12 via a wire.

[0045] In yet another variation, power supply source 76 may be a power generating device. The power generating device may be a photovoltaic power generating device that generates electricity using light from the lighting in bathroom 2 or light from a window. In another example, the power generating device may be a pressure power generating device that generates electricity using pressure generated when a button on operation unit 72 is pressed.

[0046] The speaker 78 is an output unit for outputting audio data. The microphone 79 is an input unit for inputting audio data. The vibration unit 80 is a device that vibrates the faucet remote control 12. The vibration unit 80 is a device that realizes a so-called vibration function.

In a modified example, charging port 158 ​​does not have to be located on the site where building 200 is located. In this case, charging port 158 ​​is configured to be able to wirelessly communicate with faucet control device 10 via Internet 15.

[0073] (Lighting device configuration) As shown in FIG. 2, lighting device 160 is placed on ceiling surface 6 of bathroom 2. Lighting device 160 is positioned so as to emit light downward from ceiling surface 6. Lighting device 160 is composed of LEDs. Lighting device 160 can emit light with a color temperature ranging from incandescent to daylight.

[0074] (Configuration of lighting control device) Lighting control device 162 is placed outside bathroom 2. Lighting control device 162 controls lighting device 160. As shown in FIG. 9, lighting control device 162 includes wired I / F 161, CPU 163, and memory 165.

[0075] The wired I / F 161 is connected to the communication I / F 60 (particularly the wired I / F) of the faucet control device 10, the lighting device 160, and the lighting remote control 166. The lighting control device 162 can communicate with the faucet control device 10, the lighting device 160, and the lighting remote control 166 via the wired I / F 161. In a modified example, the wired I / F 161 may be a wireless I / F. In this case, the lighting control device 162 can communicate with the faucet control device 10 via the wireless I / F. Therefore, the communication wiring connecting the lighting control device 162 and the faucet control device 10 can be omitted. In another modified example, the wired I / F 161 may be a wireless I / F and connected to the LAN 13. In this case, the lighting control device 162 can communicate with the faucet control device 10, the lighting device 160, and the lighting remote control 166 via the LAN 13.

[0076] The CPU 163 executes processing in accordance with various programs stored in the memory 165.

[0077] (Lighting remote control configuration) 2, the lighting remote control 166 is placed on the wall surface 4. As shown in FIG. 10, the lighting remote control 166 includes a wired I / F 168, a CPU 170, a memory 172, and an operation unit 174.

[0078] The wired I / F 168 is connected to the wired I / F 161 of the lighting control device 162. The lighting remote control 166 can communicate with the lighting control device 162 via the wired I / F 168. In a modified example, the wired I / F 168 may be a wireless I / F. In another modified example, the wired I / F 168 may be a wireless I / F and connected to the LAN 13.

[0079] The CPU 170 executes processing in accordance with various programs stored in the memory 172. The CPU 170 is electrically connected to the wired I / F 168 and the memory 172, and can control the operation of each of these elements. The memory 172 is configured by a ROM, a RAM, a flash memory, etc.

[0080] (Processing of faucet control devices) The following describes the processing related to the control of the motor-operated valve 9 executed by the faucet control device 10. The faucet control device 10 controls the motor-operated valve 9 by receiving instructions from each of the faucet remote control 12, the communication terminal 130, the voice input device 132, the smart mirror 134, and the lighting remote control 166.

[0081] (1st method: Control panel of the faucet remote control) In the first method, the faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the faucet remote control 12. Specifically, the user inputs the water discharge destination, temperature, and flow rate into the faucet remote control 12 by operating the operation unit of the faucet remote control 12. For example, the user inputs the water discharge destination "hand shower unit 30," the temperature "40 degrees," and the flow rate "3." In this case, the faucet remote control 12 accepts a water discharge instruction including the water discharge destination "hand shower unit," the temperature "40 degrees," and the flow rate "3." When the faucet remote control 12 accepts a water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the faucet control device 10 via the communication I / F 66. When the faucet control device 10 receives the water discharge instruction from the faucet remote control 12, it controls the motor-operated valve 9 according to the received water discharge information. As a result, water at 40 degrees is discharged from the hand shower unit 30 at a flow rate of 3.

[0082] Here, the water discharge instruction is an example of a "first instruction." The water discharge information is an example of "first instruction information."

[0083] The following describes the operation of the operation section of the faucet remote control 12 in the first method. The user can input the water discharge destination, temperature, and flow rate by operating multiple buttons 72a.

[0084] In another example, the user can input the temperature and flow rate by rotating the rotary operation unit 72b. In this case, the water discharge instruction includes the rotation speed and amount of rotation of the rotary operation unit 72b. The faucet control device 10 adjusts at least one of the temperature and flow rate according to the rotation speed and amount of rotation. Specifically, when the user rotates the rotary operation unit 72b by a first amount at a first speed, the faucet control device 10 raises the temperature by 1°C. When the user rotates the rotary operation unit 72b by the first amount at a second speed faster than the first speed, the temperature raises by 5°C. In this way, the faucet control device 10 adjusts at least one of the temperature and flow rate of the motor-operated valve 9 according to the rotation speed and amount of rotation of the rotary operation unit 72b. This provides high user convenience. The rotation speed and amount of rotation of the rotary operation unit 72b are examples of a "rotation state."

[0085] In another example, a user can input the temperature and flow rate of the overhead shower unit 32 by operating one of the multiple buttons 72a. When the overhead shower unit 32 is discharging water in a first discharge mode (i.e., shower mode), the user operates one of the multiple buttons 72a. In response to the button operation on the faucet remote control 12, the faucet control device 10 adjusts the motor-operated valve 9 to change the discharge mode of the overhead shower unit 32 from the first discharge mode to the second discharge mode (i.e., mist mode). In this way, by operating the button, the user can execute an instruction to simultaneously change at least one of the temperature and flow rate continuously for a certain period of time. This provides a high level of convenience for the user.

[0086] (Second method: microphone on the faucet remote control) The faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the faucet remote control 12. Specifically, the user inputs the water discharge destination, temperature, and flow rate into the faucet remote control 12 by speaking into the microphone 79 of the faucet remote control 12. For example, the user speaks into the microphone 79 to specify the water discharge destination "overhead shower unit," the temperature "45 degrees," and the flow rate "5." In this case, the faucet remote control 12 accepts a water discharge instruction including the water discharge destination "overhead shower unit," the temperature "45 degrees," and the flow rate "5." When the faucet remote control 12 accepts a water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the faucet control device 10 via the communication I / F 66. When the faucet control device 10 receives the water discharge instruction from the faucet remote control 12, it controls the motor-operated valve 9 according to the received water discharge information. As a result, water at 45 degrees is discharged from the overhead shower unit 32 at a flow rate of 5. With this configuration, the user can input various instructions regarding the water discharger 202 by voice, without touching the faucet remote control 12.

[0087] (Third Way: Dialogue) The third method differs from the second method in that the faucet control device 10 can interact with the voice spoken by the user. The user speaks into the microphone 79 of the faucet remote control 12. In this case, the faucet remote control 12 transmits voice data to the faucet control device 10 via the communication I / F 66. When the faucet control device 10 receives voice data from the faucet remote control 12, it transmits the received voice data to the voice input device 132 via the LAN 13. The voice input device 132 calculates the received voice data. The voice input device 132 transmits a response signal based on the calculation result to the faucet remote control 12 via the LAN 13 and the faucet control device 10. The faucet remote control 12 outputs response voice data based on the response signal from the speaker 78. Thereafter, the user speaks again into the microphone 79. That is, the user's speech, transmission of voice data to the voice input device 132, calculation by the voice input device 132, reception of the response signal by the faucet remote control 12, and output by the speaker 78 are repeatedly executed. By executing these, the user's desired water discharge destination, temperature, and flow rate are input into the faucet remote control 12. The faucet control device 10 controls the motor-operated valve 9 according to the water discharge information already received from the faucet remote control 12, as in the second method.

[0088] With this configuration, the user can input various instructions regarding the water discharger 202 by interacting with the faucet remote control 12.

[0089] In this embodiment, the calculation of the voice data is performed by the voice input device 132, but in a modified example, the calculation may be performed by a device other than the voice input device 132. For example, it may be a gateway device 14 having an interactive function (i.e., an AI function), a communication terminal 130, or a cloud service (not shown) connected to the Internet 15.

[0090] (Fourth method: infrared sensor) In the fourth method, the faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the faucet remote control 12. Specifically, the user inputs a water discharge / stop command into the faucet remote control 12 by holding their hand over the infrared sensor 84 of the faucet remote control 12. The memory 70 of the faucet remote control 12 stores the detected results of the infrared sensor 84 and the operation to be performed by the water discharge unit 202, in association with each other. For example, suppose that holding a hand over the infrared sensor 84 is associated with the water discharge / stop command of the hand shower unit 30. When the faucet remote control 12 detects that a hand has been held over the infrared sensor 84, it accepts a water discharge / stop command for the hand shower unit 30 in accordance with the detected results. Specifically, the faucet remote control 12 transmits command information representing a water discharge command to the hand shower unit 30 to the faucet control device 10 via the communication I / F 66. When the faucet control device 10 receives instruction information from the faucet remote control 12, it controls the motor-operated valve 9 to adjust whether the hand shower unit 30 spouts or stops water.

[0091] In another example, the memory 70 may associate holding a hand below the infrared sensor 84 with the water discharge / stop of the faucet unit 34. In this case, when the infrared sensor 84 detects that a hand has been held below, the faucet remote control 12 receives an instruction to discharge / stop water from the faucet unit 34 in accordance with the detection result.

[0092] (5th method: Gesture sensor) The fifth method differs from the fourth method in that instructions are received by a gesture sensor 86 instead of the infrared sensor 84. The gesture sensor 86 detects gestures (e.g., raising a hand) performed by the user in the bathroom 2. The gesture sensor 86 can identify and detect different types of gestures. The memory 70 stores gestures associated with operations to be performed by the water discharger 202. For example, a user's gesture of raising a hand may be associated with the discharge / stop of water from the overhead shower unit 32. When the gesture sensor 86 detects the user's gesture of raising a hand, the faucet remote control 12 receives an instruction to discharge / stop water from the overhead shower unit 32 in accordance with the detected gesture. Specifically, the faucet remote control 12 transmits instruction information indicating whether to discharge / stop water from the overhead shower unit 32 to the faucet control device 10 via the communication I / F 66. When the faucet control device 10 receives instruction information from the faucet remote control 12, it controls the motor-operated valve 9 to adjust the water discharge / stop of the overhead shower unit 32.

[0093] The infrared sensor 84 and the gesture sensor 86 allow the user to input various instructions related to the water discharger 202 without touching the faucet remote control 12, i.e., in a touchless manner. The infrared sensor 84 and the gesture sensor 86 are each an example of a "non-contact sensor."

[0094] (Sixth Method: Communication Terminal 130) In the sixth method, the faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the communication terminal 130. Specifically, the user inputs the water discharge destination, temperature, and flow rate into the communication terminal 130 by operating the operation unit of the communication terminal 130. For example, the user inputs the water discharge destination "hand shower unit 30," the temperature "40 degrees," and the flow rate "3." In this case, the communication terminal 130 accepts a water discharge instruction including the water discharge destination "hand shower unit," the temperature "40 degrees," and the flow rate "3." When the communication terminal 130 accepts a water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the faucet control device 10 via the LAN 13. When the faucet control device 10 receives the water discharge instruction from the communication terminal 130, it controls the motor-operated valve 9 according to the received water discharge information. As a result, water at 40 degrees is discharged from the hand shower unit 30 at a flow rate of 3. Here, the communication terminal 130 is an example of a "terminal device." The water discharge instruction is an example of a "second instruction." The water discharge information is an example of "second instruction information."

[0095] With this configuration, the user can control the motor-operated valve 9 from the communication terminal 130 even when the user is located outside the bathroom 2 in the building 200. For example, the user can cause the overhead shower unit 32 to spray mist-like water while in the living room. By spraying water, the temperature and humidity in the bathroom 2 increase. By performing this before taking a bath, the temperature and humidity in the bathroom 2 can be adjusted to a comfortable level. Furthermore, when there is a concern about pipe freezing, the pipes can be prevented from freezing by spraying water from a specified water discharge unit 202.

[0096] In another example, the communication terminal 130 does not need to be located inside the building 200. That is, the communication terminal 130 communicates with the faucet control device 10 via the Internet 15 without belonging to the LAN 13. In this case, when the communication terminal 130 receives a water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the faucet control device 10 via the Internet 15 and the gateway device 14. When the faucet control device 10 receives the water discharge instruction from the communication terminal 130, it controls the motor-operated valve 9 according to the received water discharge information. With this configuration, the user can input various instructions regarding the water discharge unit 202 while away from home.

[0097] (Seventh Method: Voice Input Device 132) In the seventh method, the faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the voice input device 132. Specifically, the user speaks into the microphone of the voice input device 132 to input the water discharge destination, temperature, and flow rate to the voice input device 132. For example, the user speaks into the microphone to specify the water discharge destination "overhead shower unit," the temperature "45 degrees," and the flow rate "5." In this case, the voice input device 132 accepts a water discharge instruction including the water discharge destination "overhead shower unit," the temperature "45 degrees," and the flow rate "5." When the voice input device 132 accepts a water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the faucet control device 10 via the LAN 13. When the faucet control device 10 receives the water discharge instruction from the voice input device 132, it controls the motor-operated valve 9 according to the received water discharge information. As a result, water at 45 degrees is discharged from the overhead shower unit 32 at a flow rate of 5. With this configuration, when the user is in a location other than bathroom 2 within building 200, the user can input various instructions regarding water discharger 202 by voice. In a modified example, voice input device 132 may be capable of calculating the received voice data. That is, the user may input various instructions regarding water discharger 202 by interacting with voice input device 132. Here, the "voice input device" is an example of a "terminal device." Instruction information representing a water discharge instruction is an example of a "second instruction."

[0098] (Method 8; Smart Mirror 134) In the eighth method, the faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the smart mirror 134. Specifically, the user inputs the water discharge destination, temperature, and flow rate into the smart mirror 134 by operating the operation unit of the smart mirror 134 located in the bathroom 2. For example, the user inputs the water discharge destination "hand shower unit 30," the temperature "40 degrees," and the flow rate "3." In this case, the communication terminal 130 accepts a water discharge instruction including the water discharge destination "hand shower unit," the temperature "40 degrees," and the flow rate "3." When the smart mirror 134 accepts the water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the faucet control device 10 via the LAN 13. When the faucet control device 10 receives the water discharge instruction from the smart mirror 134, it controls the motor-operated valve 9 according to the received water discharge information. As a result, water at 40 degrees is discharged from the hand shower unit 30 at a flow rate of 3.

[0099] (9th Method; Lighting Remote Control 166) In the ninth method, the faucet control device 10 controls the motor-operated valve 9 by receiving instructions from the lighting remote control 166. Specifically, the user inputs the water discharge destination, temperature, and flow rate into the smart mirror 134 by operating the operation unit of the lighting remote control 166. For example, the user inputs the water discharge destination "hand shower unit 30," the temperature "40 degrees," and the flow rate "3." In this case, the communication terminal 130 accepts a water discharge instruction including the water discharge destination "hand shower unit," the temperature "40 degrees," and the flow rate "3." When the lighting remote control 166 accepts a water discharge instruction from the user, it transmits instruction information representing the water discharge instruction to the lighting control device 162 via the wired I / F 168. When the lighting control device 162 receives the instruction information from the lighting remote control 166, it transmits the received instruction information to the faucet control device 10 via the wired I / F 161. When the faucet control device 10 receives a water discharge instruction from the lighting control device 162, it controls the motor-operated valve 9 according to the received water discharge information. As a result, water at 40 degrees is discharged from hand shower part 30 at a flow rate of 3.

[0100] In this embodiment, the faucet remote control 12, communication terminal 130, voice input device 132, smart mirror 134, and lighting remote control 166 receive instructions related to water discharge from the user. When each device 12, 130, 132, 134, and 166 receives an instruction, it transmits instruction information representing the instruction to the faucet control device 10. The faucet control device 10 controls the motor-operated valve 9 in accordance with the received instruction information. With this configuration, the temperature and flow rate of water discharged from the water discharge unit 202 are appropriately adjusted. The faucet remote control 12, communication terminal 130, voice input device 132, smart mirror 134, and lighting remote control 166 are each an example of a "reception device."

[0101] (10th Method: User Information) The faucet control device 10 controls the motor-operated valve 9 based on the user information stored in the user table 106 in the memory 70.

[0102] The faucet control device 10 first identifies the user operating the faucet remote control 12. Specifically, the user is identified by operating the operation unit 72 of the faucet remote control 12 and selecting a username that identifies the user. In another example, the user may be identified from the user's voice pattern acquired from the microphone 79 of the faucet remote control 12. In another example, the user may be identified from the user's movement pattern acquired from the gesture sensor 86 and the human body detection sensor 90.

[0103] The faucet control device 10 identifies the date of birth associated with the identified user name from the user table 106. If the faucet control device 10 determines from the identified date of birth that the user is a child (e.g., under the age of 10), it increases the temperature when discharging water from the overhead shower unit 32. This configuration allows water at an appropriate temperature to be discharged even when a child, like the user, is showering at a relatively low location.

[0104] The faucet control device 10 identifies the body temperature from the health information associated with the identified user name in the user table 106. If the identified body temperature is relatively low, the faucet control device 10 lowers the temperature when discharging water from the hand shower unit 30.

[0105] The faucet control device 10 identifies the water discharge information associated with the identified user name from the user table 106. For example, if the water discharge information associated with the identified user name "U1" is the water discharge unit "hand shower unit," the temperature "40°C," and the flow rate "2," the faucet control device 10 controls the motor-operated valve 9 based on the water discharge information. As a result, water at 40°C is discharged from the hand shower unit 30 at a flow rate of 2.

[0106] The faucet control device 10 identifies the customized setting information associated with the identified user name from the user table 106. The faucet control device 10 controls the motor-operated valve 9 based on the first setting information. Specifically, the faucet control device 10 controls the motor-operated valve 9 in a first pattern. This causes 40°C water to be discharged from the hand shower unit 30 at a flow rate of 3. Next, the faucet control device 10 controls the motor-operated valve 9 in a second pattern. This causes 45°C water to be discharged from the overhead shower unit 32 at a flow rate of 4. The faucet control device 10 stores the user's preferred temperature and flow rate as a pattern. This eliminates the need for the user to adjust the temperature and flow rate each time they use the faucet. The user can switch between the first and second patterns by operating button 72a on the faucet remote control 12. This provides high user convenience.

[0107] The faucet control device 10 identifies location information associated with the identified user name from the user table 106. The faucet control device 10 controls the motor-operated valve 9 based on the location information. For example, if the location information is the nearest station to the building 200, the faucet control device 10 automatically discharges high-temperature water in a mist state from the overhead shower unit 32. This increases the temperature and humidity in the bathroom 2. When the user arrives at the building 200 from the nearest station and enters the bathroom 2, the temperature and humidity in the bathroom 2 have been appropriately adjusted. The user's comfort is enhanced.

[0108] With this configuration, the faucet control device 10 controls the motor-operated valve 9 in accordance with the user information. Therefore, the water discharger 202 can discharge water at an appropriate temperature and flow rate in accordance with the user information.

[0109] In this embodiment, the user information is stored in the memory 70 of the faucet remote control 12, but in a modified example, the user information may be stored in the memory 64 of the faucet control device 10 or in the memory of the management server 16. When the user information is stored in the management server 16, the user can use, for example, the customization setting information even in a location other than the building 200 (for example, their home).

[0110] (11th method: Information obtained from the server) The faucet control device 10 controls the motor-operated valve 9 based on weather information, temperature information, date and time information, and disaster information acquired from the external server 120.

[0111] The faucet control device 10 receives at least one of weather information, temperature information, and date and time information stored in the external server 120 via the Internet 15. The faucet control device 10 controls the motor-operated valve 9 based on at least one of the received weather information, temperature information, and date and time information. Specifically, if the faucet control device 10 determines that the temperature is high based on at least one of the weather information, temperature information, and date and time information, it sets the temperature to a relatively low level when discharging water from the water discharge unit 202. If the faucet control device 10 determines that the temperature is low based on at least one of the weather information, temperature information, and date and time information, it sets the temperature to a relatively high level when discharging water from the water discharge unit 202. If the faucet control device 10 determines that it is morning based on the date and time information, it adjusts the temperature to a level that allows the user to feel refreshed when discharging water from the water discharge unit 202.

[0112] Furthermore, if the faucet control device 10 determines that the humidity is high based on at least one of the weather information, temperature information, and date and time information, it automatically discharges low-temperature water in a mist state from the overhead shower unit 32 after the user has taken a bath. This prevents mold from growing in the bathroom 2. If the faucet control device 10 determines that the temperature is low based on at least one of the weather information, temperature information, and date and time information, it automatically discharges high-temperature water in a mist state from the overhead shower unit 32 before the user has taken a bath. This increases the temperature and humidity in the bathroom 2. This prevents heat shock from occurring.

[0113] Furthermore, if the faucet control device 10 determines that the temperature is significantly low based on at least one of the weather information, temperature information, and date and time information, it automatically controls the motor-operated valve 9 to drain the water from the pipes. Alternatively, if the faucet control device 10 determines that the temperature is significantly low, it can prevent the pipes from freezing by automatically controlling the motor-operated valve 9 to discharge water from a specified water discharge section 202. Weather information, temperature information, and date and time information are each an example of "specific information."

[0114] With this configuration, the faucet control device 10 can control the motor-operated valve 9 based on information acquired from the external server 120. Therefore, the water discharge unit 202 can discharge water at an appropriate temperature and flow rate according to the information acquired from the external server 120.

[0115] (Method 12: Surrounding environment of the water outlet) The faucet control device 10 controls the motor-operated valve 9 according to the ambient environment of the water discharge portion 202.

[0116] The faucet control device 10 controls the motor-operated valve 9 to perform pipe cleaning. Pipe cleaning is performed according to the frequency of use of the water discharger 202. For example, if the water discharger 202 is used frequently, pipe cleaning is performed every predetermined time (e.g., every 24 hours). If the water discharger 202 is used infrequently, pipe cleaning is performed every predetermined number of times (e.g., every five times).

[0117] The faucet control device 10 controls the motor-operated valve 9 to drain water stored in an electric water heater (not shown). The electric water heater is inserted into a pipe from a water supply source to the water discharge unit 202. The water stored in the electric water heater is drained according to the frequency of use of the water discharge unit 202. For example, if the water discharge unit 202 is used frequently, the water is drained every predetermined time (e.g., every 24 hours). If the water discharge unit 202 is used infrequently, the water is drained every predetermined number of times (e.g., every five times).

[0118] With this configuration, the faucet control device 10 can flush the pipes and drain the water stored in the electric water heater by controlling the motor-operated valve 9 according to the frequency of use of the water discharge portion 202. The frequency of use of the water discharge portion 202 is an example of the "ambient environment of the water discharge portion."

[0119] Next, the process executed by the faucet control device 10 regarding the control of the lighting device 160 will be described.

[0120] The faucet control device 10 receives at least one of weather information, temperature information, and date and time information stored in the external server 120 via the Internet 15. The faucet control device 10 controls the lighting device 160 based on at least one of the received weather information, temperature information, and date and time information. Specifically, when the faucet control device 10 determines that the temperature is high based on at least one of the weather information, temperature information, and date and time information, it sets the color temperature of the lighting device 160 to daylight. The faucet control device 10 transmits a signal for controlling the lighting device 160 to the lighting control device 162 via the communication I / F 60. The lighting control device 162 controls the lighting device 160 in accordance with the received signal.

[0121] When the faucet control device 10 determines that the temperature is low based on at least one of the weather information, temperature information, and date and time information, it sets the color temperature of the lighting device 160 to warm white. When the faucet control device 10 determines that it is cloudy based on at least one of the weather information, temperature information, and date and time information, it increases the illuminance of the lighting device 160.

[0122] The faucet control device 10 receives disaster information stored in the external server 120 via the Internet 15. The faucet control device 10 controls the lighting device 160 based on the received disaster information. Specifically, if the received disaster information indicates the occurrence of an earthquake, the faucet control device 10 turns on the lighting device 160. This allows the user to avoid having to evacuate in the dark.

[0123] With this configuration, the faucet control device 10 can control the lighting device 160 based on information acquired from the external server 120. Disaster information is an example of "specific information."

[0124] (Processing related to the interlocking of the function executing device and the motor-operated valve) Next, a description will be given of the processing executed by the faucet control device 10 regarding the control of the function executing device 136. The faucet control device 10 controls the function executing device 136 and the motor-operated valve 9 so as to operate in conjunction with each other.

[0125] Faucet control device 10 controls bathroom dryer 140 and motor-operated valve 9 to operate in conjunction with each other. Specifically, faucet control device 10 operates bathroom dryer 140 in a drying mode after the user has taken a bath. This prevents mold from growing in bathroom 2. Faucet control device 10 also sprays mist-like water from overhead shower unit 32 when drying clothes in bathroom 2. Next, faucet control device 10 operates bathroom dryer 140 in a drying mode. By spraying water on the clothes before the bathroom dryer 140 starts its drying mode, wrinkles in the clothes are smoothed out. Pollen is also removed from the clothes.

[0126] When the user is taking a bath, faucet control device 10 operates bathroom dryer 140 in heating mode and sprays high-temperature water in mist form from overhead shower unit 32. This creates a mist sauna environment in bathroom 2.

[0127] The faucet control device 10 controls the bathroom heater 141 and the motor-operated valve 9 to operate in conjunction with each other. Specifically, the bathroom heater 141 is operated after the user has finished bathing. This ensures that the temperature in the bathroom is appropriately adjusted when the user finishes bathing and enters the bathroom. The user can spend time in the bathroom comfortably. The occurrence of heat shock can be suppressed.

[0128] Faucet control device 10 controls bathroom audio 142 to operate in conjunction with motor-operated valve 9. Specifically, faucet control device 10 switches the sound and music output from bathroom audio 142 in accordance with the water discharge pattern of overhead shower unit 32. This increases user comfort.

[0129] Faucet control device 10 controls water heater 146 and motor-operated valve 9 to operate in conjunction with each other. Specifically, when water heater 146 detects that a user is bathing in bathtub 8, faucet control device 10 automatically stops the discharge of water from hand shower unit 30.

[0130] The faucet control device 10 controls the bathroom aroma diffuser 148 to operate in conjunction with the motor-operated valve 9. Specifically, the faucet control device 10 operates the bathroom aroma diffuser 148 when water is discharged from the overhead shower unit 32. The faucet control device 10 also switches the scent diffused from the bathroom aroma diffuser 148 according to the type of water discharged from the overhead shower unit 32. This increases the comfort of the user.

[0131] The faucet control device 10 controls the front door 150 and the motor-operated valve 9 to operate in conjunction with each other. Specifically, when the faucet control device 10 detects that the front door has been opened, it automatically discharges high-temperature water in a mist state from the overhead shower unit 32. This increases the temperature and humidity in the bathroom 2. When a user enters the building 200 through the front door 150 and enters the bathroom 2, the temperature and humidity in the bathroom 2 have been appropriately adjusted. This increases the user's comfort.

[0132] Similarly, when the faucet control device 10 detects that the garage shutter 154 is open, when it detects that the gate 156 is open, or when a charging cable is inserted into the charging port 158, it automatically discharges high-temperature water in a mist state from the overhead shower unit 32. When the front door is opened, when it detects that the garage shutter 154 is open, when it detects that the gate 156 is open, or when a charging cable is inserted into the charging port 158, it is highly likely that the user has returned home to the building 200 from outside. By using these as triggers to automatically discharge high-temperature water in a mist state from the overhead shower unit 32, the user's comfort is enhanced.

[0133] The faucet control device 10 controls the bathtub cleaning unit 40 and the motor-operated valve 9 to operate in conjunction with each other. Specifically, the faucet control device 10 drains the cold water that has accumulated in the piping after the bathtub cleaning unit 40 has finished cleaning the bathtub. This prevents the cold water that has accumulated in the piping from being discharged when the user discharges water from the water discharge unit 202. This increases the user's comfort. The bathtub cleaning unit 40 is an example of a "function executing device."

[0134] The faucet control device 10 controls the smart mirror 134 and the motor-operated valve 9 to work together. Specifically, the faucet control device 10 adjusts the temperature of the water discharged from the water discharger 202 based on the user's body temperature and complexion obtained from the smart mirror 134. The smart mirror 134 is an example of a "function executing device."

[0135] With this configuration, faucet control device 10 controls bathroom dryer 140, washroom heater 41, bathroom audio 142, water heater 146, bathroom aroma diffuser 148, front door 150, garage shutter 154, gate 156, charging port 158, bathtub cleaning unit 40, and smart mirror 134 so that they are linked to motor-operated valve 9. This improves user convenience.

[0136] (Processing related to the linkage between the function executing device and the lighting device) Next, a description will be given of the processing executed by the faucet control device 10 regarding the control of the function executing device 136 and the lighting device 160. The faucet control device 10 controls the function executing device 136 and the lighting device 160 so that they work together.

[0137] The faucet control device 10 controls the bathroom display 144 and the lighting device 160 so that they operate in conjunction with each other. Specifically, when the bathroom display 144 is activated and an image such as a video is displayed, the faucet control device 10 reduces the illuminance of the lighting device 160. This increases the comfort of the user.

[0138] The faucet control device 10 controls the outside bathroom lighting 152 and the lighting device 160 so that they operate in conjunction with each other. Specifically, the faucet control device 10 detects the illuminance of the outside bathroom lighting 152 and changes the illuminance of the lighting device 160. If the illuminance of the outside bathroom lighting 152 is high, the illuminance of the lighting device 160 is also increased. If the illuminance of the outside bathroom lighting 152 is low, the illuminance of the lighting device 160 is also decreased. This reduces the difference in illuminance between the location where the outside bathroom lighting 152 is located and the bathroom 2, thereby improving user comfort.

[0139] (Processing related to the interlocking of the water outlet and lighting device) Next, a description will be given of the processing executed by the faucet control device 10 regarding the control of the water discharger 202 and the lighting device 160. The faucet control device 10 controls the water discharger 202 and the lighting device 160 so that they operate in conjunction with each other.

[0140] The faucet control device 10 controls the overhead shower unit 32 and the lighting device 160 to operate in conjunction with each other. Specifically, the faucet control device 10 switches at least one of the color temperature and illuminance of the lighting device 160 according to the water discharge pattern of the overhead shower unit 32. This increases the comfort of the user. In another example, the faucet control device 10 may light up the lighting device 160 in red when the temperature of the water discharged from the overhead shower unit 32 is high. In this case, the user can recognize that the water discharged from the overhead shower unit 32 is hot. The lighting device 160 is an example of a "state change unit."

[0141] The faucet control device 10 controls the hand shower unit 30 and the lighting device 160 to operate in conjunction with each other. Specifically, after the water discharge from the hand shower unit 30 is stopped, the color temperature and illuminance of the lighting device 160 are changed to a relaxing mode. When the water discharge from the hand shower unit 30 is stopped, it is highly likely that the user is taking a bath in the bathtub 8. This increases the user's comfort.

[0142] The faucet control device 10 controls the jet bath unit 38 to operate in conjunction with the lighting device 160. Specifically, when water is discharged from the jet bath unit 38, the color temperature and illuminance of the lighting device 160 are changed.

[0143] (Processing related to communication between the communication terminal 130 and the management server 16) Next, the process executed by the faucet control device 10 regarding communication with the management server 16 and the communication terminal 130 will be described.

[0144] The faucet control device 10 stores the flow rate of the water discharger 202 used during a specific period in memory 64. The faucet control device 10 transmits water volume information, including the flow rate of the water discharger 202 used during the specific period, to the communication terminal 130. When the communication terminal 130 receives the water volume information from the faucet control device 10, it displays the received water volume information on the display unit of the communication terminal 130. The user can recognize the water volume information by looking at the display unit of the communication terminal 130.

[0145] With this configuration, the user of the communication terminal 130 can recognize the water volume information. The user of the communication terminal 130 can determine whether the water discharge system 1 is being used normally. The display unit of the communication terminal 130 is an example of an "output unit of a terminal device."

[0146] The faucet control device 10 transmits water volume information, including the flow rate of the water discharge portion 202, used during a specific period to the management server 16. The management server 16 stores the water volume information received this time in addition to water volume information received in the past in memory 104. The management server 16 cumulatively stores the water volume information used during the specific period.

[0147] With this configuration, management server 16 can use the stored water volume information. For example, management server 16 can calculate utility costs using the stored water volume information. Management server 16 may notify communication terminal 130 of the calculated utility costs, or may provide a new service that allows users to check the calculated utility costs.

[0148] The management server 16 can use the stored water volume information to improve the efficiency of central heating systems in large facilities such as hotels.

[0149] In a modified example, the faucet control device 10 may transmit water volume information including leak detection information to the management server 16 in addition to the flow rate of the water discharge portion 202 used during a specific period. The faucet control device 10 detects a water leak by the following means. In the first means, detection is performed by a water leak sensor (not shown) placed in the piping from the water supply device to the water discharge portion 202. The faucet control device 10 detects a water leak by receiving a signal from the water leak sensor indicating that a water leak has occurred. In the second means, the faucet control device 10 detects a water leak by controlling the motor-operated valve 9 when the flow rate of the water discharge portion 202 increases when water is not being discharged from the water discharge portion 202.

[0150] When the management server 16 receives water volume information including water leakage detection information from the faucet control device 10, the management server 16 may automatically contact a service (not shown) that provides a maintenance service for the water discharge system 1.

[0151] As described above, the faucet control device 10 can detect when it is time to replace the filter and when it is time to replenish the liquid detergent. When the faucet control device 10 detects that it is time to replace the filter, it sends a notification signal containing that information to the communication terminal 130. When the communication terminal 130 receives the notification signal from the faucet control device 10, it displays the filter replacement time contained in the received notification signal on the display unit of the communication terminal 130. The user can recognize that it is time to replace the filter by looking at the display unit of the communication terminal 130. The same process is performed when it is time to replenish the liquid detergent. This allows the user to recognize that it is time to replenish the liquid detergent.

[0152] In a modified example, when the faucet control device 10 detects that it is time to replace the filter, it may display this information on the display unit 74 of the faucet remote control 12. This allows the user to know that it is time to replenish the liquid detergent. The same process is executed when it is time to replenish the liquid detergent. This allows the user to know that it is time to replenish the liquid detergent.

[0153] In yet another variation, when the faucet control device 10 detects that it is time to replace the filter, it sends a notification signal containing that information to the management server 16. When the management server 16 receives the notification signal from the faucet control device 10, it identifies the filter replacement time contained in the received notification signal. The management server 16 automatically contacts an automatic consumables shipping service (not shown). This allows the user to obtain a new filter. The same process is performed when it is time to refill the liquid detergent. This allows the user to obtain a new refill liquid detergent.

[0154] (12 functions of the faucet remote control) The specific functions of the faucet remote controller 12 will be described.

[0155] When the faucet remote control 12 receives an operation from the user on the operation unit 72, it outputs an alarm sound from the speaker 78. This allows the user to audibly recognize that the operation has been received.

[0156] When the faucet remote control 12 receives an operation from the user on the operation unit 72, it vibrates the vibration unit 80. This allows the user to recognize by touch that the operation has been received.

[0157] The faucet remote control lights up the light-emitting unit 82 according to the temperature of the water being discharged. For example, if the temperature of the water being discharged is low, the light-emitting unit 82 lights up blue. If the temperature of the water being discharged is high, the light-emitting unit 82 lights up red. The light-emitting unit 82 also flashes in the event of an abnormality. This allows the user to visually recognize information about the water being discharged. The speaker 78, the vibration unit 80, and the light-emitting unit 82 are examples of a "state change unit."

[0158] The faucet remote control 12 transmits temperature and humidity information around the faucet remote control 12, detected by the temperature and humidity sensor 88, to the communication terminal 130. The communication terminal 130 displays the received temperature and humidity information on the display unit of the communication terminal 130. The user can recognize the temperature and humidity by looking at the display unit of the communication terminal 130. The communication terminal 130 may also determine the heat shock risk and dryness level based on the received temperature and humidity information. The communication terminal 130 displays the determined heat shock risk and dryness level on the display unit of the communication terminal 130.

[0159] The faucet remote control 12 transmits information detected by the human body detection sensor 90 regarding whether or not a user is present in the bathroom 2 to the communication terminal 130. The communication terminal 130 displays the received information on the display unit of the communication terminal 130. The user can recognize whether or not the user is present in the bathroom 2. The human body detection sensor 90 may also function as a fall detection sensor for detecting a user fall. In this case, the communication terminal 130 can recognize that the user in the bathroom 2 has fallen.

[0160] Temperature and humidity information, and information regarding whether or not a user is in bathroom 2 are examples of "information related to the situation." The display unit of communication terminal 130 is an example of an "output unit."

[0161] The faucet remote control 12 can change the instructions that it can accept from a user depending on the user. Specifically, first, using the method described above, the faucet control device 10 identifies the user U1 who will operate the faucet remote control 12. The faucet remote control 12 displays on the display unit 74 display content that has been previously set in association with the identified user U1. The faucet remote control 12 sets the function input by the operation unit 72 to the function that has been previously set in association with the user U1.

[0162] A case will be described where the user operating the faucet remote control 12 is identified as user U2, who is different from user U1. The faucet remote control 12 displays, on the display unit 74, display content that has been previously set in association with the identified user U2. The faucet remote control 12 sets the function input by the operation unit 72 to the function that has been previously set in association with user U2.

[0163] In this way, the faucet remote control 12 changes the display content of the display unit 74 and the functions input by the operation unit 72 according to each of the identified users, thereby improving convenience for the multiple users.

[0164] Faucet remote control 12 can be moved around the bathroom 2, the washroom, and the kitchen. When faucet remote control 12 is installed in a first location on wall surface 4 in bathroom 2, faucet remote control 12 sets the content to be displayed on display unit 74 and the functions to be input by operation unit 72 according to the first location. Specifically, faucet remote control 12 is configured in a manner that allows input of operations to discharge water from hand shower unit 30, overhead shower unit 32, and faucet unit 34.

[0165] When faucet remote control 12 is installed in a second location on wall surface 4 in bathroom 2, faucet remote control 12 sets the display content to be displayed on display unit 74 and the functions to be input by operation unit 72, depending on the second location. Specifically, faucet remote control 12 is configured in a manner that allows input of operations to discharge water from bathtub water supply unit 36, jet bath unit 38, and bathtub cleaning unit 40.

[0166] When the faucet remote control 12 is installed in a bathroom, the faucet remote control 12 sets the display content to be displayed on the display unit 74 and the functions to be input by the operation unit 72 according to the bathroom. Specifically, the faucet remote control 12 is configured in a manner that allows input of an operation to discharge water from the bathroom water discharge unit 20.

[0167] When the faucet remote control 12 is installed in a kitchen, the faucet remote control 12 sets the display content to be displayed on the display unit 74 and the functions to be input by the operation unit 72 according to the kitchen. Specifically, the faucet remote control 12 is configured in a manner that allows input of operations for discharging water from the kitchen water discharge unit 22.

[0168] With this configuration, the faucet remote control 12 can accept user operations (i.e., instructions) to discharge water from each water discharge unit (i.e., hand shower unit 30, overhead shower unit 32, faucet unit 34, bathtub water supply unit 36, jet bath unit 38, bathtub cleaning unit 40, bathroom water discharge unit 20, and kitchen water discharge unit 22) depending on the installation location of the faucet remote control 12. Therefore, one faucet remote control 12 can be used in multiple locations.

[0169] (Second embodiment) The second embodiment differs from the first embodiment in that the display unit of the faucet remote control 12 functions as a touch panel.

[0170] The faucet remote control 12 includes a display unit 374. The display unit 374 is a display for displaying various information and also functions as a touch panel. That is, the display unit 374 also functions as the operation unit 372.

[0171] The display unit 374 of the faucet remote control 12 functions as a touch panel, making it possible to easily change the displayed content (i.e., the operable functions). That is, the faucet remote control 12 can change the displayed content depending on the user or the installation location of the faucet remote control 12 itself.
