Description

[Technical field]

[0001] The disclosed embodiments relate to a bathroom appliance system. [Background technology]

[0002] Conventionally, a bathroom equipment system is known in which a power supply box with a ground fault circuit interrupter is placed above the ceiling of a bathroom unit (see, for example, Patent Document 1). For example, such a bathroom equipment system is provided with multiple overcurrent protection devices that can cut off the power supply to multiple bathroom-related devices, and suppresses the shutdown of devices other than the device through which an overcurrent flows in response to the detection of power by each of the multiple overcurrent protection devices.

[0003] [Patent Document 1] Patent Publication No. 2021-158735 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the above-mentioned conventional technology. For example, in the above-mentioned conventional technology, an overcurrent protection device is required for each bathroom-related device among the multiple bathroom-related devices that receive power from the power box in order to identify an abnormality such as which bathroom-related device has experienced an overcurrent. In addition, for example, the above-mentioned conventional technology has a problem in that it is not possible to recognize signs of an abnormality in a bathroom-related device unless an abnormality (failure) such as an overcurrent occurs in the bathroom-related device. Thus, there is room for improvement in the above-mentioned conventional technology in terms of system configuration, and it is desirable to enable flexible control of each of the multiple bathroom-related devices through detection in the power box.

[0005] One aspect of the embodiment aims to enable flexible control of each of a plurality of bathroom-related devices through detection in a power box. [Means for solving the problem]

[0006] A bathroom equipment system according to one aspect of an embodiment comprises a plurality of bathroom-related devices, an operating power supply unit that generates operating power for operating the plurality of bathroom-related devices from AC power supplied through a distribution board installed in the home, and a power supply box having an overcurrent protection unit, wherein each of the plurality of bathroom-related devices has a plurality of power control units that control the operating power supplied from the power supply box, and the overcurrent protection unit has a detection unit that detects the current flowing through each of the plurality of power control units, and a current monitoring and interruption unit that monitors the current flowing through the plurality of power control units based on the detection result by the detection unit and sends a signal to each of the plurality of power control units to instruct them to pass or cut off the flow of power, and the current monitoring and interruption unit has a memory unit that stores a precursor monitoring current value, which is a current value that predicts a failure of each of the plurality of bathroom-related devices, and when the detection result by the detection unit is a current value outside the range of the precursor monitoring current value, it sends a signal to cut off the flow of electricity to the power control unit of the bathroom-related device corresponding to the precursor monitoring current value.

[0007] According to a bathroom equipment system according to one aspect of the embodiment, the current flowing through the multiple bathroom-related devices is monitored, and a signal for controlling the supply of power to each of the multiple bathroom-related devices is transmitted in response to the current flowing. For example, the bathroom equipment system monitors the current for operating the multiple devices, the remote control, and the communication device, and compares the current with a predetermined current range that indicates a malfunction of each of the bathroom-related devices stored in the memory unit. This allows the bathroom equipment system to identify the location of the malfunctioning power control unit and cut off the power supply to the specific power control unit, thereby enabling early repair and recovery and determination of the malfunctioning location before the bathroom-related device malfunctions. In addition, the bathroom equipment system can prevent damage from spreading to other devices by cutting off the power supply to the part that indicates a malfunction in advance, so that the power supply to the power control unit with no abnormality in the current flowing thereto is not cut off, and the device that receives power from the power control unit with no abnormality can continue to be used as is. In this way, the bathroom equipment system can prevent the power supply to the communication device from being cut off, for example, even if a current outside the range that indicates a malfunction flows through the operating power supply unit that supplies power to one of the devices and the power supply to that device is cut off. This allows the bathroom equipment system to, for example, detect equipment malfunctions while the user is outside the house, allowing the user to deal with the malfunction quickly and preventing situations in which the user is unable to take a bath when they return home. Therefore, the bathroom equipment system can flexibly control each of multiple bathroom-related devices through detection by the power supply box.

[0008] For example, in conventional bathroom equipment systems, a protection mechanism is provided for each control unit of the equipment, so that even if an overcurrent flows through any one of the equipment, the protection mechanism of the power box is activated and the entire bathroom equipment system is stopped. As a result, in conventional bathroom equipment systems, if an overcurrent flows through any one of the equipment that receives power from the power box, the power supply to all equipment is stopped, preventing all equipment from stopping operation.

[0009] However, in conventional bathroom equipment systems, it is not possible to identify the location where the overcurrent has flowed, and it may take time to identify whether the functional unit is located in the ceiling or in the bathroom space during repairs, which may result in a long wait before recovery. In addition, in conventional bathroom equipment systems, if the overcurrent is below the threshold of the equipment's protection mechanism, the operation of the equipment through which the overcurrent is flowing may become unstable, or the power supply may be overloaded when other equipment is operating simultaneously, causing a current greater than the rated power supply to flow, and in the event of a power supply failure, all equipment may stop operating. On the other hand, the bathroom equipment system according to one aspect of the embodiment uses the above-mentioned processing to enable repair and recovery in a short period of time in the event of a failure due to overcurrent, making it possible to provide a bathroom equipment system that users can use with greater peace of mind.

[0010] In one aspect of the embodiment, the bathroom equipment system has a monitoring mode in which the detection unit sequentially detects the current flowing through each of the multiple power control units, and if the detection result by the detection unit in the monitoring mode is a current value outside the range of the precursor monitoring current value, the current monitoring cut-off unit sends a signal to the power control unit to cut off the flow of electricity.

[0011] According to one aspect of the embodiment, the bathroom equipment system has a monitoring mode that sequentially detects the current flowing through each of the multiple power control units, making it possible to quickly repair and restore the bathroom-related equipment and determine the location of the failure before all of the bathroom-related equipment breaks down. Therefore, the bathroom equipment system can flexibly control each of the multiple bathroom-related equipment through detection by the power supply box.

[0012] A bathroom equipment system in one embodiment includes a communication box arranged between the power supply box and the multiple bathroom-related devices, each of which has a communication unit connected to the power control unit, and when the detection result by the detection unit is a current outside the range of the precursor monitoring current value, the current monitoring cut-off unit sends a signal to the power control unit via the communication box and the communication unit to cut off the flow of electricity.

[0013] According to one aspect of the embodiment, a bathroom equipment system includes a communication box between the power supply box and multiple bathroom-related devices, and by consolidating communication with the communication units of each bathroom-related device in the communication box, information on the current value flowing through each power control unit can be consolidated in the communication box. Furthermore, since the bathroom equipment system does not need to provide a detection unit in each bathroom device, current monitoring can be performed efficiently. Therefore, the bathroom equipment system can flexibly control each of the multiple bathroom-related devices through detection in the power supply box.

[0014] A bathroom equipment system in one embodiment includes a remote control that accepts operations related to the bathroom equipment system, and when power to any of the plurality of bathroom-related devices is cut off, the current monitoring and interruption unit sends a signal to the remote control, causing a display unit of the remote control to display the bathroom-related device that has been cut off.

[0015] According to one aspect of the embodiment, the bathroom equipment system has a notification means, which allows for early repair and recovery, and identification of the location of the failure. Therefore, the bathroom equipment system can flexibly control each of the multiple bathroom-related devices through detection by the power supply box. [Brief description of the drawings]

[0017] Hereinafter, an embodiment of the bathroom equipment system disclosed in the present application will be described in detail with reference to the attached drawings. Note that the present invention is not limited to the embodiment described below. It should be noted that the drawings are schematic, and the dimensional relationships and ratios of each element may differ from the reality. There may also be parts in which the dimensional relationships and ratios differ between the drawings.

[0018] A bathroom equipment system 1 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the configuration of a bathroom equipment system according to an embodiment. Note that in block diagrams such as Fig. 1, only components necessary for explaining the features of this embodiment are shown as functional blocks, and descriptions of general components are omitted.

[0019] In other words, each component shown in a block diagram such as Figure 1 is a functional concept, and does not necessarily have to be physically configured as shown. For example, the specific form of distribution and integration of each functional block is not limited to that shown in the figure, and all or part of it can be functionally or physically distributed and integrated in any unit according to various loads, usage conditions, etc.

[0020] As shown in Figure 1, bathroom equipment system 1 comprises multiple bathroom-related devices 2, such as a bathroom cleaning device 2A, an automatic drain plug 2B, and a communication device 2C, as well as a power supply box 3, a communication box 4, and a remote control 5. Figure 1 shows a case where the multiple bathroom-related devices 2 include devices installed in a bathroom 100 (see Figure 2), such as the bathroom cleaning device 2A, the automatic drain plug 2B, and the communication device 2C.

[0021] The multiple bathroom-related devices 2 are not limited to bathroom cleaning device 2A, automatic drain plug 2B, communication device 2C, etc., but may include any device related to a bathroom. For example, the multiple bathroom-related devices 2 may include AV equipment, lighting, etc. For example, AV equipment may include an audio component with an audio playback function, or a television with a video playback function. The multiple bathroom-related devices 2 may also include a remote control 5. When describing the multiple bathroom-related devices 2, such as the bathroom cleaning device 2A, automatic drain plug 2B, communication device 2C, without making any particular distinction between them, they may be referred to as "bathroom-related devices 2."

[0022] The bathroom-related device 2 is supplied with power via the communication box 4. For example, the bathroom-related device 2 is supplied with power from the power supply box 3 via the communication box 4. The bathroom-related device 2 transmits and receives information via the communication box 4. For example, the bathroom-related device 2 receives information for performing various controls from the communication box 4. For example, the bathroom-related device 2 receives information (signals) from the communication box 4 indicating instructions to switch a third switch and a fourth switch, which will be described later, etc. Note that the above is merely one example, and the bathroom-related device 2 may transmit and receive various information necessary for processing between the communication box 4 depending on the functions that the bathroom-related device 2 has, etc.

[0023] Bathroom cleaning device 2A has a cleaning function for cleaning bathroom 100. For example, bathroom cleaning device 2A cleans floor 103 of bathroom 100 (see FIG. 2) by spraying sterilized water or water (or hot water) onto the floor 103 of bathroom 100. Bathroom cleaning device 2A may also include a bathtub cleaning device for cleaning bathtub 105 (see FIG. 2).

[0024] Automatic drain plug 2B opens and closes the drain valve of bathtub 105. Automatic drain plug 2B drains water (or hot water) from bathtub 105 when opened, and makes bathtub 105 ready to start filling with water, for example, when closed.

[0025] The communication device 2C receives a control signal by wireless communication from the wireless router 6, and transmits the received control signal via wired communication to a device (e.g., the communication box 4) provided in the bathroom 100. For example, a gateway device can be used as the communication device 2C.

[0026] In bathroom equipment system 1, communication device 2C is capable of wireless communication with wireless router 6. Wireless router 6 is also communicatively connected to terminal device 7 via communication network N such as the Internet.

[0027] Remote control 5 accepts operations related to bathroom equipment system 1. For example, remote control 5 is a device (operating device) for operating equipment (bathroom cleaning device 2A, etc.) provided in bathroom 100. In other words, remote control 5 is a device that controls the equipment provided in bathroom 100. Remote control 5 transmits control signals that control bathroom cleaning device 2A, etc., in response to user operation. The control signals transmitted from remote control 5 are output to the corresponding bathroom cleaning device 2A, etc. Remote control 5 may also control a water heater, etc.

[0028] The remote control 5 also has a display unit such as a display, and functions as a display device that displays various information. The remote control 5 outputs various information received from the communication box 4. The remote control 5 outputs various information such as an alert notification. The remote control 5 displays information related to an abnormality received from the communication box 4. For example, the remote control 5 displays information received from the communication box 4 indicating the bathroom-related device 2 in which a sign of an abnormality has been detected.

[0029] The wireless router 6 receives a control signal transmitted from the terminal device 7, and transmits the received control signal to the communication device 2C via wireless communication. The wireless router 6 also receives a signal related to the operating state of the appliances installed in the bathroom 100 via the communication device 2C via wireless communication, and transmits the received signal to the terminal device 7 via the communication network N. The wireless communication in the wireless router 6 can be, for example, WiFi (registered trademark), but is not limited to this, and other types of wireless communication such as Bluetooth (registered trademark) may also be used.

[0030] The terminal device 7 is a terminal device used by a user. As the terminal device 7, a mobile terminal device such as a smartphone can be used, but is not limited to this. For example, the terminal device 7 may be other devices such as a tablet terminal, a wearable terminal, a personal computer, etc. The terminal device 7 may be multiple.

[0031] Terminal device 7 is able to transmit a control signal to bathroom cleaning device 2A to control equipment provided in bathroom 100, such as bathroom cleaning device 2A. For example, when a user operates terminal device 7 to start an application for controlling bathroom cleaning device 2A, terminal device 7 transmits a control signal to control bathroom cleaning device 2A. The control signal is input to bathroom cleaning device 2A via wireless router 6, communication device 2C and communication box 4.

[0032] Furthermore, terminal device 7 can receive, via communication box 4, communication device 2C, and wireless router 6, signals relating to the operating status of equipment provided in bathroom 100, for example bathroom cleaning device 2A.

[0033] Terminal device 7 may also have a display unit such as a display, and function as a display device that displays various information. In this case, bathroom equipment system 1 may output various information such as an alert notification by terminal device 7. For example, communication device 2C may transmit information indicating bathroom-related device 2 in which a sign of an abnormality has been detected to terminal device 7, and terminal device 7 may display the information indicating bathroom-related device 2 in which a sign of an abnormality has been detected received from communication device 2C. In this way, terminal device 7 may function as a display device that displays information related to bathroom-related device 2. For example, terminal device 7 displays information indicating bathroom-related device 2 in which a sign of an abnormality has been detected on a display unit. For example, terminal device 7 may function as a remote control that accepts operations related to bathroom equipment system 1.

[0034] The power supply box 3 generates operating power for operating the multiple bathroom-related devices 2. The power supply box 3 will be described in detail later.

[0035] The communication box 4 is disposed between the power supply box 3 and the multiple bathroom-related devices 2. The communication box 4 is connected to the multiple bathroom-related devices 2 by wires. The communication box 4 supplies operating power provided from the power supply box 3 to the multiple bathroom-related devices 2. The communication box 4 also functions as a hub connecting the multiple bathroom-related devices 2. The communication box 4 transmits a control signal transmitted by wired communication from the communication device 2C to a device provided in the bathroom 100 that corresponds to the control signal.

[0036] A plurality of bathroom-related devices 2, a power supply box 3, and a communication box 4 are arranged in a bathroom 100, for example, as shown in Fig. 2. Fig. 2 is a schematic diagram showing a bathroom according to an embodiment. The bathroom 100 is, for example, a unit bath.

[0037] Bathroom 100 includes a number of walls 101 (for example, four walls), a ceiling 102, and a floor 103. Walls 101, ceiling 102, and floor 103 are formed, for example, from dedicated panels (for example, steel panel) that constitute a unit bath.

[0038] Inside bathroom 100, bathroom space 104 is formed, surrounded by walls 101, ceiling 102, and floor 103. Bathroom space 104 is equipped with plumbing fixtures such as a bathtub 105 and a shower faucet (not shown). Outside bathroom 100, a distribution board 110 is installed to which AC power is supplied from a commercial power source.

[0039] Communications device 2C, power supply box 3, and communications box 4 are installed above the ceiling, i.e., on the upper surface of ceiling 102. Power control box unit 21A of bathroom cleaning device 2A and power control box unit 21B of automatic drain plug 2B are also installed above the ceiling. Each power control box unit 21A, 21B is connected to communications box 4 by wire, and controls the operating power supplied to the corresponding bathroom-related device 2.

[0040] The remote control 5 is provided on a wall 103 or the like of the bathroom 100. An inspection hatch 102a is provided in the ceiling 102. A worker or the like can access the power supply box 3, the communication box 4, the power control box units 21A and 21B, the communication device 2C, and the like from the inspection hatch 102a to perform work.

[0041] Next, the power supply box 3 will be described with reference to Fig. 3. Fig. 3 is a block diagram showing the configuration of the power supply box according to the embodiment.

[0042] The power supply box 3 is supplied with AC power from a distribution board 110 provided in the house. The power supply box 3 includes an operation power supply unit 30 and an overcurrent protection device 31 which is an overcurrent protection unit.

[0043] Operational power supply unit 30 converts AC power supplied via distribution board 110 into DC power. Operational power supply unit 30 generates operating power from the AC power for operating multiple bathroom-related devices 2. Operational power supply unit 30 converts the voltage of the power supplied from distribution board 110 into a DC voltage of 24 V, for example.

[0044] The operating power generated by operating power supply unit 30 is supplied to multiple bathroom-related devices 2 (see FIG. 1) via communication box 4. In FIG. 3, operating power supply unit 30 supplies the generated operating power to communication box 4 via connection line LN1 corresponding to a first switch 33 described below.

[0045] Overcurrent protection device 31 monitors the current flowing through the multiple bathroom-related devices 2, and transmits a signal instructing each of the multiple bathroom-related devices 2 to turn on or off the power. For example, overcurrent protection device 31 transmits a signal instructing each bathroom-related device 2 to turn on or off the power to the corresponding bathroom-related device 2 via communication box 4. In FIG. 3, overcurrent protection device 31 communicates with communication box 4 via connection line LN2 corresponding to second switch 34 described later, and transmits and receives information to and from communication box 4.

[0046] When overcurrent protection device 31 detects a current that is a sign of a failure in at least one of the multiple bathroom-related devices 2, it transmits a signal to cut off the flow of electricity to the bathroom-related device 2 that is predicted to have a failure. Furthermore, when overcurrent protection device 31 detects a current that is a sign of a failure in communication box 4, it transmits a signal to cut off the flow of electricity to communication box 4. For example, when there is a sign of a failure in communication box 4, overcurrent protection device 31 may cut off the flow of electricity to operating power supply unit 30.

[0047] For example, overcurrent protection device 31 may cut off the power supply to operating power unit 30 when an overcurrent that is a sign of a failure of communication box 4 flows through operating power unit 30. Specifically, overcurrent protection device 31 may cut off the power supply to operating power unit 30 when a current equal to or greater than an overcurrent threshold flows through operating power unit 30 for an overcurrent determination time or longer. The overcurrent threshold and the overcurrent determination time are preset values. When overcurrent protection device 31 cuts off the power supply to operating power unit 30, power to all of the bathroom-related devices 2 is cut off.

[0048] As shown in Fig. 4, the overcurrent protection device 31 includes a current detection unit 32, a first switch 33, a second switch 34, and a current monitoring and interruption unit 35. Fig. 4 is a block diagram showing the configuration of the overcurrent protection device according to the embodiment.

[0049] Current detection unit 32 functions as a detection unit that detects current. Current detection unit 32 detects the value of the current that flows. For example, current detection unit 32 detects the current that flows through power supply box 3. Current detection unit 32 is, for example, a current detection circuit. Current detection unit 32 detects the current that flows through operation power supply unit 30. For example, current detection unit 32 detects the current that flows through each of the multiple bathroom-related devices 2 by detecting the current that flows through operation power supply unit 30.

[0050] For example, in the monitoring mode, if a current that is a sign of a failure of bathroom-related device 2 flows through operating power supply unit 30, overcurrent protection device 31 may cut off the flow of electricity to bathroom-related device 2. Specifically, in the monitoring mode, if a current outside the range of the sign-monitoring current value corresponding to the bathroom-related device 2 to be judged flows through operating power supply unit 30 for longer than the judgment time corresponding to the sign-monitoring current value, overcurrent protection device 31 may cut off the flow of electricity to bathroom-related device 2.

[0051] The first switch 33 switches the energizing state of the operating power supply unit 30. Specifically, when the first switch 33 is "ON," it energizes the operating power supply unit 30. When the first switch 33 is "OFF," it cuts off the energization of the operating power supply unit 30.

[0052] The second switch 34 switches the communication state of the abnormality alert to the communication box 4. Specifically, when the second switch 34 is "ON", the communication of information related to the abnormality alert is performed to the communication box 4. When the second switch 34 is "OFF", the communication of information related to the abnormality alert is cut off to the communication box 4.

[0053] The current monitoring and interrupting unit 35 includes a storage unit 36 ​​and a control unit 37. The storage unit 36 ​​is realized by a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 36 ​​is a computer-readable recording medium that non-temporarily records data used by an information processing program.

[0054] The memory unit 36 ​​stores various information used to predict signs of failure. The memory unit 36 ​​stores a current value for monitoring for signs including a current value that predicts a failure of each of the multiple bathroom-related devices 2. The memory unit 36 ​​stores a current value for monitoring for signs including a current value that predicts a failure of each of the communication boxes 4. For example, the memory unit 36 ​​stores a current value for monitoring for signs including a current value that predicts a failure of at least one of the multiple bathroom-related devices 2 and the communication box 4.

[0055] For example, the storage unit 36 ​​stores each of the precursor monitoring current values ​​in association with information indicating an appliance corresponding to the precursor monitoring current value. For example, the storage unit 36 ​​stores each of the precursor monitoring current values ​​in association with information indicating a determination time corresponding to the precursor monitoring current value.

[0056] The storage unit 36 ​​also stores information related to modes. For example, the storage unit 36 ​​stores information related to conditions for switching between a normal mode, which is a mode during normal operation, and a monitoring mode, which is a mode for monitoring for signs of failure. For example, the storage unit 36 ​​stores information (timing information) indicating the timing for executing the monitoring mode. For example, the storage unit 36 ​​stores timing information indicating the time (e.g., 2:00 a.m.) for starting execution of the monitoring mode.

[0057] For example, memory unit 36 ​​stores timing information specifying the timing when the use of bathroom 100 stops as the timing for executing the monitoring mode. For example, memory unit 36 ​​stores timing information specifying the timing when people leave bathroom 100 as the timing for executing the monitoring mode. For example, memory unit 36 ​​stores timing information specifying the timing when the lights in bathroom 100 are turned off as the timing for executing the monitoring mode. Note that the above is merely an example, and memory unit 36 ​​stores various information used for processing, not limited to the above.

[0058] The control unit 37 includes a determination unit 371, a measurement unit 372, and an instruction unit 373. The control unit 37 includes, for example, a computer having a central processing unit (CPU), a read only memory (ROM), a RAM, an input / output port, and various other circuits.

[0059] The CPU of the computer functions as the determination unit 371, the measurement unit 372, and the instruction unit 373 of the control unit 37, for example, by reading and executing a control program stored in the ROM. At least one or all of the determination unit 371, the measurement unit 372, and the instruction unit 373 may be configured with hardware such as an ASIC (Application Specific Integrated Circuit), a GPU (Graphics Processing Unit), an FPGA (Field Programmable Gate Array), etc. The current monitoring and interrupting unit 35 may be configured with an electric circuit.

[0060] The determination unit 371 executes a determination process to determine whether or not the current detected by the current detection unit 32 indicates a sign of failure in at least one of the multiple bathroom-related devices 2 and the communication box 4. For example, the determination unit 371 executes the determination process using the current value detected by the current detection unit 32. For example, the determination unit 371 executes the determination process using the sign monitoring current value stored in the storage unit 36. For example, when the result of detection by the current detection unit 32 is a current value outside the range of the sign monitoring current value, the determination unit 371 determines that there is a sign of failure in the device corresponding to the sign monitoring current value.

[0061] The determination unit 371 may execute a determination process using information measured by the measurement unit 372. The determination unit 371 may determine whether or not the time measured by the measurement unit 372 is equal to or longer than a determination time corresponding to the sign monitoring current value. For example, the determination unit 371 may determine whether or not the time measured by the measurement unit 372 is equal to or longer than an overcurrent determination time.

[0062] The measurement unit 372 measures information related to detection by the current detection unit 32. When the current detected by the current detection unit 32 is outside the range of the current value for monitoring for an indication, the measurement unit 372 measures the time during which the current outside the range of the current value for monitoring for an indication flows.

[0063] When the current detected by the current detection unit 32 is equal to or greater than the overcurrent threshold, the measurement unit 372 measures the time during which a current equal to or greater than the overcurrent threshold flows. Specifically, the measurement unit 372 measures the time during which a current equal to or greater than the overcurrent threshold flows continuously.

[0064] Instructing unit 373 transmits information indicating various instructions according to the result of the determination by determining unit 371. If determining unit 371 determines that there is a sign of a malfunction, instructing unit 373 transmits to communication box 4 a signal to cut off the supply of electricity to the device corresponding to the sign monitoring current value. If determining unit 371 determines that there is a sign of a malfunction in bathroom-related device 2, instructing unit 373 transmits to communication box 4 a signal to cut off the supply of electricity to bathroom-related device 2.

[0065] Furthermore, when the determination unit 371 determines that the communication box 4 has a sign of failure, the instruction unit 373 executes a process of cutting off power to the communication box 4. When the determination unit 371 determines that the communication box 4 has a sign of failure, the instruction unit 373 turns the first switch 33 "OFF." When the time measured by the measurement unit 372 is equal to or longer than the overcurrent determination time, the instruction unit 373 may turn the first switch 33 "OFF." That is, the instruction unit 373 may cut off power to the operating power supply unit 30 when a current equal to or greater than the overcurrent threshold flows for equal to or longer than the overcurrent determination time.

[0066] Next, each bathroom-related device 2 will be described with reference to Fig. 5. Fig. 5 is a block diagram showing the configuration of each bathroom-related device according to the embodiment.

[0067] Bathroom cleaning device 2A comprises bathroom cleaning device main body unit 20A and power control box unit 21A. Bathroom cleaning device main body unit 20A contains the components required for performing the cleaning function of cleaning bathroom 100. Power control box unit 21A comprises power control unit 22A, communication unit 23A, third switch 24A and fourth switch 25A.

[0068] Power control unit 22A controls the operating power supplied to bathroom cleaning apparatus 2A. For example, power control unit 22A controls the operating power supplied to bathroom cleaning apparatus 2A by controlling third switch 24A, fourth switch 25A, etc. For example, power control unit 22A controls the power supplied to main body unit 20A of the bathroom cleaning apparatus.

[0069] The communication unit 23A is realized by, for example, a communication circuit or the like, and transmits and receives information to and from the communication box 4. For example, the communication unit 23A is connected to the communication box 4 by wire or wirelessly, and transmits and receives information, signals, and the like to and from the communication box 4. The communication unit 23A transmits the information, signals, and the like received from the communication box 4 to each part of the power control box unit 21A.

[0070] For example, the communication unit 23A transmits a signal received from the communication box 4 for controlling (instructing) the ON / OFF (on / off) of the third switch 24A to the third switch 24A. Also, for example, the communication unit 23A transmits various information received from the communication box 4 to the power control unit 22A. For example, the communication unit 23A transmits a signal received from the communication box 4 for controlling (instructing) the ON / OFF (on / off) of the fourth switch 25A to the fourth switch 25A via the power control unit 22A.

[0071] Third switch 24A switches the power supply state of bathroom cleaning device 2A in response to control by communications box 4 via communications unit 23A. Third switch 24A switches the power supply state of bathroom cleaning device 2A in response to a signal received from communications box 4 via communications unit 23A. Third switch 24A cuts off power to bathroom cleaning device 2A in response to control by communications box 4 via communications unit 23A.

[0072] Third switch 24A may cut off the flow of electricity to bathroom cleaning device 2A in response to control by power control unit 22A. For example, third switch 24A cuts off the flow of electricity to bathroom cleaning device 2A if an overcurrent flows through power control unit 22A. Specifically, third switch 24A cuts off the flow of electricity to power control unit 22A if a current equal to or greater than the overcurrent threshold flows through power control unit 22A for longer than the overcurrent determination time.

[0073] The overcurrent threshold of each bathroom-related device 2, such as the bathroom cleaning device 2A, may be a different value. For example, the overcurrent threshold of each bathroom-related device 2 may be set to any value smaller than the overcurrent threshold of the power supply box 3. The overcurrent judgment time of each bathroom-related device 2, such as the bathroom cleaning device 2A, may be a different value. For example, the overcurrent judgment time of each bathroom-related device 2 may be set to any value shorter than the overcurrent judgment time of the power supply box 3.

[0074] The third switch 24A switches the state of current supply to the power control unit 22A. Specifically, when the third switch 24A is "ON," it supplies current to the power control unit 22A. When the third switch 24A is "OFF," it cuts off current supply to the power control unit 22A.

[0075] The fourth switch 25A switches the power supply state of main body unit 20A of the bathroom cleaning device in response to control by communication box 4 via communication unit 23A. The fourth switch 25A switches the power supply state of main body unit 20A of the bathroom cleaning device in response to control by power control unit 22A. The fourth switch 25A switches the power supply state of main body unit 20A of the bathroom cleaning device in response to a signal received from communication box 4 via communication unit 23A. The fourth switch 25A cuts off the power supply to main body unit 20A of the bathroom cleaning device in response to control by power control unit 22A.

[0076] Fourth switch 25A switches the state of electricity supply to main body 20A of the bathroom cleaning device. Specifically, when fourth switch 25A is "ON," electricity passes through main body 20A of the bathroom cleaning device. When fourth switch 25A is "OFF," electricity is cut off to main body 20A of the bathroom cleaning device.

[0077] Returning to Fig. 5, automatic drain plug 2B includes automatic drain plug main body 20B and power control box 21B. Automatic drain plug main body 20B includes components for opening and closing the drain valve of bathtub 105. Power control box 21B includes power control unit 22B, communication unit 23B, third switch 24B, and fourth switch 25B.

[0078] The power control unit 22B controls the operating power supplied to the automatic drain plug 2B. For example, the power control unit 22B controls the operating power supplied to the automatic drain plug 2B by controlling the third switch 24B and the fourth switch 25B, etc. For example, the power control unit 22B controls the power supplied to the main body 20B of the automatic drain plug.

[0079] The communication unit 23B is realized by, for example, a communication circuit or the like, and transmits and receives information to and from the communication box 4. For example, the communication unit 23B is connected to the communication box 4 by wire or wirelessly, and transmits and receives information, signals, and the like to and from the communication box 4. The communication unit 23B transmits the information, signals, and the like received from the communication box 4 to each part of the power control box unit 21B.

[0080] Third switch 24B switches the power supply state of automatic drain plug 2B according to control by communications box 4 via communications unit 23B or control by power control unit 22B. It may also cut off power to automatic drain plug 2B if an overcurrent flows through power control unit 22B. The specific configuration of third switch 24B is the same as that of third switch 24A in bathroom cleaning device 2A, so a detailed description will be omitted.

[0081] Fourth switch 25B switches the power supply state of automatic drain plug main body 20B according to control by communication box 4 via communication unit 23B or control by power control unit 22B. The specific configuration of fourth switch 25B is the same as that of fourth switch 25A in bathroom cleaning device 2A, so a detailed description will be omitted.

[0082] The communication device 2C includes a communication device main body 20C, a power control section 22C, a communication section 23C, a third switch 24C, and a fourth switch 25C. The communication device main body 20C includes components for transmitting and receiving control signals.

[0083] The power control unit 22C controls the operating power supplied to the communication device 2C. For example, the power control unit 22C controls the operating power supplied to the communication device 2C by controlling the third switch 24C, the fourth switch 25C, etc. For example, the power control unit 22C controls the power supplied to the main body unit 20C of the communication device.

[0084] The communication unit 23C is realized by, for example, a communication circuit or the like, and transmits and receives information to and from the communication box 4. For example, the communication unit 23C is connected to the communication box 4 by wire or wirelessly, and transmits and receives information, signals, and the like to and from the communication box 4. The communication unit 23C transmits information, signals, and the like received from the communication box 4 to each part of the communication device 2C. In addition, the communication unit 23C may transmit and receive information to and from other devices such as the terminal device 7 via a wireless router 6 or the like.

[0085] Third switch 24C switches the power supply state of communication device 2C according to control by communication box 4 via communication unit 23C or control by power control unit 22C. It may also cut off power to communication device 2C if an overcurrent flows through power control unit 22C. The specific configuration of third switch 24C is the same as that of third switch 24A in bathroom cleaning device 2A, so a detailed description will be omitted.

[0086] Fourth switch 25C switches the power supply state of main body 20C of the communications device under control of communications box 4 via communications unit 23C or under control of power control unit 22C. The specific configuration of fourth switch 25C is the same as that of fourth switch 25A in bathroom cleaning device 2A, so a detailed description will be omitted.

[0087] The above-mentioned bathroom cleaning device 2A, automatic drain plug 2B, communication device 2C, etc. are merely examples of bathroom-related equipment 2, and bathroom-related equipment 2 other than those described above have the same configuration as that described above. When describing the bathroom cleaning device main body 20A, the automatic drain plug main body 20B, the communication device main body 20C, etc. without distinguishing between them, they may be described as "bathroom-related equipment main body 20".

[0088] Furthermore, when describing the power control units 22A, 22B, 22C, etc. without distinguishing between them, they may be written as "power control unit 22," and when describing the communication units 23A, 23B, 23C, etc. without distinguishing between them, they may be written as "communication unit 23." When describing the third switch 24A, 24B, 24C, etc. without distinguishing between them, they may be written as "third switch 24," and when describing the fourth switch 25A, 25B, 25C, etc. without distinguishing between them, they may be written as "fourth switch 25."

[0089] As described above, bathroom-related device 2 includes bathroom-related device main body 20, power control unit 22, communication unit 23, third switch 24, and fourth switch 25. Power control unit 22 controls the operating power supplied to bathroom-related device 2. Communication unit 23 is realized by, for example, a communication circuit, etc., and transmits and receives information to and from communication box 4.

[0090] Third switch 24 switches the power-on state of bathroom-related device 2 in response to control by communication box 4 via communication unit 23 or control by power control unit 22. Fourth switch 25 switches the power-on state of main body 20 of the bathroom-related device in response to control by communication box 4 via communication unit 23 or control by power control unit 22.

[0091] In this way, each bathroom-related device 2 has a power control unit 22 that controls the operating power supplied from the power supply box 3. Each bathroom-related device 2 has a communication unit 23 connected to the power control unit 22. The power supply box 3 executes various processes for each bathroom-related device 2, the communication box 4, etc. For example, the overcurrent protection device 31 of the power supply box 3 shown in Figures 3 and 4 executes processes related to the supply of power to each bathroom-related device 2, the communication box 4, and other devices.

[0092] The overcurrent protection device 31 detects the current flowing through each of the multiple power control units 22 using the current detection unit 32. The overcurrent protection device 31 monitors the current flowing through the multiple power control units 22 based on the detection result by the current detection unit 32 using the current monitoring and interruption unit, and transmits a signal to each of the multiple power control units 22 to instruct the supply or interruption of power.

[0093] The overcurrent protection device 31 has a memory unit 36 ​​that stores a precursor monitoring current value that predicts a failure of each of the multiple bathroom-related devices 2, and when the detection result by the current detection unit 32 is a current value outside the range of the precursor monitoring current values, it sends a signal to cut off the flow of electricity to the power control unit 22 of the bathroom-related device 2 that corresponds to the precursor monitoring current value.

[0094] The overcurrent protection device 31 has a monitoring mode in which the current detection unit 32 sequentially detects the current flowing through each of the multiple power control units 22 and obtains the detection result. When the detection result by the current detection unit 32 in the monitoring mode is a current value outside the range of the symptom monitoring current value, the overcurrent protection device 31 transmits a signal to the power control unit 22 to cut off the current.

[0095] When the detection result by current detection unit 32 is a current outside the range of the symptom monitoring current value, overcurrent protection device 31 transmits a signal to power control unit 22 to cut off the flow of electricity via communication box 4 and communication unit 23. When the flow of electricity to any of the multiple bathroom-related devices 2 is cut off, overcurrent protection device 31 transmits a signal to remote control 5 to cause the display unit of remote control 5 to display information indicating the bathroom-related device 2 whose power has been cut off.

[0096] Next, an example of processing executed by bathroom equipment system 1 according to the embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an example of processing executed by the bathroom equipment system according to the embodiment. For example, the processing shown in Fig. 6 is executed when the mode in bathroom equipment system 1 (e.g., a mode managed by power supply box 3) becomes a monitoring mode.

[0097] When bathroom equipment system 1 is described as the processing subject, that processing may be performed by any device included in bathroom equipment system 1 that is capable of executing that processing, depending on the device configuration included in bathroom equipment system 1. For example, depending on the device configuration of bathroom equipment system 1, that processing may be performed by any device that is capable of executing the processing, including bathroom-related equipment 2, power supply box 3, communication box 4, remote control 5, wireless router 6, terminal device 7, etc.

[0098] First, bathroom equipment system 1 performs current detection (step S101). For example, when power supply box 3 enters monitoring mode, current detection unit 32 detects the current flowing through operating power supply unit 30 during standby. For example, power supply box 3 detects the value of the current that flows when each bathroom-related device 2 and communication box 4 are in a powered state as the standby current value.

[0099] Then, bathroom equipment system 1 determines whether the standby current value is normal or not (step S102). For example, power supply box 3 determines whether the standby current value is normal or not using information indicating the normal standby current value stored in memory unit 36.

[0100] If bathroom equipment system 1 determines that the standby current value is normal (step S102: Yes), it proceeds to a process of determining whether the operating current value is normal or not. In FIG. 6, if bathroom equipment system 1 determines that the standby current value is normal, it proceeds to the process of step S107 and onwards. In this case, bathroom equipment system 1 may turn off both third switch 24 and fourth switch 25. For example, power supply box 3 compares the standby current value with a normal value, and if the difference between the standby current value and the normal value is within a predetermined range, it determines that the standby current value is normal and proceeds to a process of determining whether the operating current value is normal or not.

[0101] If bathroom equipment system 1 determines that the standby current value is not normal (step S102: No), it turns off all switches (step S103). For example, power supply box 3 compares the standby current value with a normal value, and if the difference between the standby current value and the normal value is outside a predetermined range, it determines that the standby current value is not normal and turns off first switch 33, second switch 34, third switch 24, and fourth switch 25. In this case, for example, the standby current value may be the current value in a state in which first switch 33, second switch 34, third switch 24, and fourth switch 25 are all ON.

[0102] Then, bathroom equipment system 1 turns on first switch 33 (step S104). For example, power supply box 3 turns on first switch 33 of overcurrent protection device 31.

[0103] Then, bathroom equipment system 1 determines whether the current value (also referred to as the "first current value") when only first switch 33 is turned ON is normal (step S105). For example, power supply box 3 determines whether the first current value detected by current detection unit 32 is outside the range of current values ​​for monitoring for a sign of a failure in communication box 4.

[0104] If bathroom equipment system 1 determines that the first current value when only first switch 33 is turned ON is not normal (step S105: No), it identifies communications box 4 as abnormal and turns OFF first switch 33 (step S106). Bathroom equipment system 1 then notifies or records the abnormal part through the process shown in step S115, and ends the process. For example, if the first current value detected by current detection unit 32 is outside the range of current values ​​for monitoring signs that indicate a failure in communications box 4, power supply box 3 determines that there is a sign of a failure in communications box 4 and turns OFF first switch 33.

[0105] Then, the power supply box 3 stores information indicating that the communication box 4 is a part corresponding to a sign of failure (abnormality) in the storage unit 36. Note that, when the power supply box 3 is capable of communicating with the remote control 5 without going through the communication box 4, the power supply box 3 may transmit a signal to the remote control 5 to display information indicating that the communication box 4 is a part corresponding to a sign of failure (abnormality). In this case, the remote control 5 displays information indicating that the communication box 4 is a part corresponding to a sign of failure (abnormality) based on the received signal.

[0106] If bathroom equipment system 1 determines that the first current value when only first switch 33 is turned ON is normal (step S105: Yes), it repeats the process of steps S107 to S113 (also referred to as the "bathroom-related equipment determination process") according to the number of bathroom-related devices 2. For example, if the first current value detected by current detection unit 32 is within a range of a sign monitoring current value that indicates a failure of the communications box 4, power supply box 3 determines that there is no sign of a failure in the communications box 4, and repeatedly executes the bathroom-related equipment determination process for each of the multiple bathroom-related devices 2.

[0107] First, bathroom equipment system 1 selects one of the undetermined bathroom-related devices 2 as a target device and turns ON third switch 24 of that target device (step S107). For example, power supply box 3 references flags stored in memory unit 36 ​​associated with each bathroom-related device 2 and indicating whether or not a determination process has been performed, selects one of the bathroom-related devices 2 whose flag indicates whether or not a determination process has been performed as the target device, and turns ON third switch 24 of that target device. For example, if power supply box 3 selects bathroom cleaning device 2A as the target device, it instructs bathroom cleaning device 2A via communication box 4 to turn ON third switch 24A of bathroom cleaning device 2A.

[0108] Bathroom equipment system 1 then determines whether the current value (also referred to as the "second current value") when third switch 24 of the target equipment is turned ON is normal (step S108). For example, power supply box 3 determines whether the second current value detected by current detection unit 32 is outside the range of current values ​​for monitoring for signs of a failure of the target equipment. For example, when the target equipment is bathroom cleaning device 2A, power supply box 3 determines whether the second current value detected by current detection unit 32 is outside the range of current values ​​for monitoring for signs of a failure of bathroom cleaning device 2A.

[0109] If bathroom equipment system 1 determines that the second current value when third switch 24 of the target device is turned ON is not normal (step S108: No), it identifies the target device as abnormal and issues an alert to communication box 4 via second switch 34 (step S109). Bathroom equipment system 1 then notifies or records the abnormal part through the process shown in step S115, and ends the process. For example, if the second current value detected by current detection unit 32 is outside the range of current values ​​for monitoring signs that predict a failure of the target device, power supply box 3 determines that the target device has a sign of failure. Power supply box 3 stores information in memory unit 36 ​​indicating that the target device is a part that corresponds to a sign of failure (abnormality).

[0110] Then, power supply box 3 turns on second switch 34 and sends information to communication box 4 indicating that the target device is showing signs of failure, thereby alerting communication box 4. On receiving the alert, communication box 4 sends a signal to remote control 5 to display information indicating that the target device is a part that corresponds to a sign of failure (abnormality). Based on the received signal, remote control 5 displays information indicating that the target device is a part that corresponds to a sign of failure (abnormality). For example, if the target device is bathroom cleaning device 2A, remote control 5 receives a signal to display information indicating that bathroom cleaning device 2A is a part that corresponds to a sign of failure (abnormality), and displays information indicating that bathroom cleaning device 2A is a part that corresponds to a sign of failure (abnormality).

[0111] If bathroom equipment system 1 determines that the second current value when third switch 24 of the target equipment is turned ON is normal (step S108: Yes), it turns ON fourth switch 25 of the target equipment (step S110). For example, if the second current value detected by current detection unit 32 is within a range of a sign monitoring current value that predicts a failure of the target equipment, power supply box 3 turns ON fourth switch 25 of the target equipment. For example, if the target equipment is bathroom cleaning device 2A, power supply box 3 instructs bathroom cleaning device 2A via communication box 4 to turn ON fourth switch 25A of bathroom cleaning device 2A.

[0112] Bathroom equipment system 1 then determines whether the current value (also referred to as the "third current value") when fourth switch 25 of the target equipment is turned ON is normal (step S111). For example, power supply box 3 determines whether the third current value detected by current detection unit 32 is outside the range of current values ​​for monitoring for signs of a failure of the target equipment. For example, when the target equipment is bathroom cleaning equipment 2A, power supply box 3 determines whether the third current value detected by current detection unit 32 is outside the range of current values ​​for monitoring for signs of a failure of main body unit 20A of the bathroom cleaning equipment.

[0113] If bathroom equipment system 1 determines that the third current value when fourth switch 25 of the target device is turned ON is not normal (step S111: No), it identifies that main body 20 of the target device is abnormal and issues an alert to communication box 4 via second switch 34 (step S112). Bathroom equipment system 1 then notifies or records the abnormal part through the process shown in step S115, and ends the process. For example, if the third current value detected by current detection unit 32 is outside the range of current values ​​for monitoring signs that indicate a failure of main body 20 of the target device, power supply box 3 determines that there is a sign of failure in main body 20 of the target device. Power supply box 3 stores information in memory unit 36 ​​indicating that main body 20 of the target device is a part that corresponds to a sign of failure (abnormality).

[0114] Then, power supply box 3 turns on second switch 34 and sends information to communication box 4 indicating that there is a sign of failure in main body 20 of the target device, thereby alerting communication box 4. On receiving the alert, communication box 4 sends a signal to remote control 5 to display information indicating that main body 20 of the target device is a part that corresponds to a sign of failure (abnormality). Based on the received signal, remote control 5 displays information indicating that main body 20 of the target device is a part that corresponds to a sign of failure (abnormality). For example, if the target device is bathroom cleaning device 2A, remote control 5 receives a signal to display information indicating that main body 20A of the bathroom cleaning device is a part that corresponds to a sign of failure (abnormality), and displays information indicating that main body 20A of the bathroom cleaning device is a part that corresponds to a sign of failure (abnormality).

[0115] If bathroom equipment system 1 determines that the third current value when fourth switch 25 of the target equipment is turned ON is normal (step S111: Yes), it determines whether there is any bathroom-related equipment 2 that has not been determined (step S113). For example, if the third current value detected by current detection unit 32 is within the range of the sign monitoring current value that predicts a failure in main body unit 20 of the target equipment, power supply box 3 determines that there is no sign of failure in main body unit 20 of the target equipment, and refers to memory unit 36 ​​to determine whether there is any bathroom-related equipment 2 for which the bathroom-related equipment determination process has not been executed.

[0116] If bathroom equipment system 1 determines that there is an undetermined bathroom-related device 2 (step S113: No), it returns to step S107 and repeats the bathroom-related device determination process. For example, if at least one of the flags associated with each of the bathroom-related devices 2 stored in memory unit 36 ​​indicates that the determination process has not been executed, power supply box 3 determines that there is an undetermined bathroom-related device 2, and returns to step S107 and repeats the bathroom-related device determination process.

[0117] When returning to step S107 to repeat the bathroom-related equipment determination process, bathroom equipment system 1 may turn OFF third switch 24 and fourth switch 25 of the target equipment for which the bathroom-related equipment determination process has been completed. In this case, after turning OFF third switch 24 and fourth switch 25 of the target equipment, bathroom equipment system 1 returns to step S107 to repeat the bathroom-related equipment determination process.

[0118] If bathroom equipment system 1 determines that there is no undetermined bathroom-related device 2 (step S113: Yes), it turns off control of main body 20 of bathroom-related device 2 (step S114) and ends the process. For example, power supply box 3 determines that there is no undetermined bathroom-related device 2 if all of the flags associated with each of the bathroom-related devices 2 stored in memory unit 36 ​​indicate that the determination process has been executed. Then, in order to turn off control of main body 20 of bathroom-related device 2, power supply box 3 turns off, for example, third switch 24 or fourth switch 25 of each bathroom-related device 2, and ends the process.

[0119] As described above, bathroom equipment system 1 provides overcurrent protection device 31, which functions as a current monitoring mechanism, in power supply box 3, which is the power supply unit. Bathroom equipment system 1 also pre-stores the current during operation and standby of each device, such as bathroom-related device 2 and communication box 4, and monitors increases and decreases in current to identify fault conditions. Bathroom equipment system 1 also provides the control unit of each device (such as power control unit 22) with a function to control the supply of power, and if an abnormal current is flowing or signs of an abnormal current are detected, it will stop the supply of power to that device. Bathroom equipment system 1 then notifies the user of any devices that have an abnormality by displaying it on remote control 5 in bathroom 100 or by displaying an abnormality in the control unit's memory device, etc.

[0120] The above-described configuration of bathroom equipment system 1 is merely one example, and bathroom equipment system 1 can have any configuration as long as it can perform the desired process. For example, fuses may be used as at least a part of first switch 33, second switch 34, third switch 24, and fourth switch 25. In this case, bathroom equipment system 1 can reduce the cost of overcurrent protection devices.

[0121] In bathroom equipment system 1, third switch 24 may be provided separately from bathroom-related device 2. For example, bathroom equipment system 1 may provide at least one of third switches 24 in communication box 4. Bathroom equipment system 1 may also provide multiple third switches 24 integrally. In this case, bathroom equipment system 1 can reduce the space in which bathroom-related device 2 is arranged.

[0122] Bathroom equipment system 1 may include devices such as a bathroom dryer / heater. Bathroom equipment system 1 may be a system that does not include some of the bathroom-related equipment 2. Bathroom equipment system 1 may have bathroom-related equipment 2 connected to power supply box 3 without going through communication box 4.

[0123] The above-described embodiments and modifications can be appropriately combined as long as the processing contents are not contradictory.
