The second wiring 60 is arranged on the ceiling 102 of the bathroom 100 so as not to overlap with the first wirings 51 to 54.

FIG. 2 is a perspective view illustrating the communication hub according to the first embodiment.
As shown in FIG. 2, the communication hub 40 has a case 46, first connector sections 41 to 44, and a second connector section 45.

  The case 46 is a housing of the communication hub 40. The case 46 has, for example, a substantially rectangular parallelepiped shape. The communication hub 40 is arranged, for example, with the lower surface of the case 46 facing the ceiling 102 of the bathroom 100. The lower surface of the case 46 is fixed to, for example, the ceiling 102.

  The first connection connector portions 41 to 44 are connection portions for connecting the first wirings 51 to 54. In other words, the first connection connector units 41 to 44 are connection units for connecting the first to fourth control units 21 a to 24 a of the first to fourth function units 21 to 24 and the communication hub 40.

In other words, the communication hub 40 is arranged on the ceiling 102 of the bathroom 100 such that the first connection connectors 41 to 44 face the inspection port 104.

  Further, the communication hub 40 makes it possible to distinguish the first connector 41 from the other first connectors 42 to 44. The communication hub 40 has, for example, a marker 47 that allows the first connector 41 to be distinguished from the other first connectors 42 to 44. The sign unit 47 is, for example, a character or an illustration displayed on the case 46. The indicator 47 includes that the color of the first connector 41 is different from the colors of the other first connectors 42 to 44. Note that the communication hub 40 may be provided with a marker 47 that can distinguish each of the first connection connectors 41 to 44.

  The second connection connector section 45 is a connection section for connecting the second wiring 60. In other words, the second connection connector section 45 is a connection section for connecting the remote controller 30 and the communication hub 40. The second connector portion 45 is provided, for example, on one of the upper surface and the four side surfaces of the case 46. In this example, the second connector 45 is provided on one of the side surfaces of the case 46. Further, in this example, the second connector 45 is provided on the same surface as the surface on which the first connectors 41 to 44 are provided. That is, the second connection connector section 45 is provided in the same direction as the first connection connector sections 41 to 44.

  Further, in this example, the second connection connector portions 45 are arranged so as to be aligned with the first connection connector portions 41 to 44 which are arranged so as to be aligned in a horizontal direction. The arrangement of the second connector 45 is not limited to this, and may be any arrangement. In addition, the communication hub 40 may be provided with a sign portion capable of distinguishing the second connection connector portion 45 from the first connection connector portions 41 to 44. In addition, by making the shape of the second connector portion 45 different from the shape of the first connector portions 41 to 44, the second connector portion 45 and the first connector portions 41 to 44 can be distinguished. it can.

  Note that the number of the first connection connector section and the number of the second connection connector section can be set to arbitrary numbers, respectively. The number of the first connection connectors may be appropriately selected according to the number of the functional units to be connected. The number of the second connection connectors is, for example, one.

FIG. 3 is a block diagram illustrating a bathroom system according to the first embodiment.
As shown in FIG. 3, the first to fourth functional units 21 to 24 are connected to the remote controller 30 via the communication hub 40. More specifically, the first to fourth control units 21a to 24a of the first to fourth functional units 21 to 24 are respectively connected to the first connection connector unit of the communication hub 40 via the first wires 51 to 54. 41 to 44 are connected. The control unit 34 of the remote controller 30 is connected to the second connector 45 of the communication hub 40 via the second wiring 60.

The control unit 34 of the remote control 30 is connected to the operation unit 32 and the display unit 36 of the remote control 30. The control unit 34 of the remote control 30 is connected to the determination unit 80. When the user operates the operation unit 32 of the remote control 30, a signal S1 is transmitted from the control unit 34 of the remote control 30 to the first to fourth control units 21a to 24a of the first to fourth function units 21 to 24. Is done. The signal S1 includes a control signal for at least one of the first to fourth control units 21a to 24a. Signal S1 is a common control signal.
The determining unit 80 may be provided separately and separately from the remote controller 30, and may be configured such that the first function unit 21 and the remote controller 30 are connected via the determining unit 80.

  The signal S1 is transmitted to each of the first to fourth control units 21a to 24a via the communication hub 40. In other words, for example, a control signal (a control signal for operating the first functional unit 21) to the first control unit 21a is transmitted not only to the first control unit 21a but also to the second to fourth control units 22a to 24a. Is also sent. Each of the first to fourth control units 21a to 24a controls the operation of the first to fourth function units 21 to 24 according to the signal S1.

  At this time, for example, each of the first to fourth control units 21a to 24a determines whether or not the signal S1 includes a control signal for operating a functional unit controlled by itself. For example, when the signal S1 is a control signal for the first control unit 21a, the first control unit 21a determines that the signal S1 includes a control signal for operating the first function unit 21, and 21 is operated. On the other hand, the second to fourth control units 22a to 24a determine that the control signal for operating the second to fourth functional units 22 to 24 is not included in the signal S1, and -24 are not operated.

  Each of the first to fourth control units 21a to 24a transmits a signal S2 to the control unit 34 of the remote controller 30 after receiving the signal S1, for example. The signal S2 includes, for example, a signal regarding the operation state of at least one of the first to fourth functional units 21 to 24.

  The signal S2 is transmitted to the control unit 34 of the remote controller 30 through the communication hub 40. At this time, for example, the signal S2 (the signal about the operation state of the first function unit 21) from the first control unit 21a is transmitted not only to the control unit 34 of the remote control 30 but also to the second to fourth control units 22a to 24a. Is also sent. The control unit 34 of the remote controller 30 displays the operation state of the first function unit 21 on the display unit 36 of the remote controller 30 according to the signal S2, for example.

  As described above, the communication hub 40 connects the control unit 34 of the remote controller 30 to the first to fourth control units 21a to 24a of the first to fourth functional units 21 to 24, and connects the control unit 34 of the remote controller 30 to the It mediates communication by the signals S1 and S2 between the first to fourth control units 21a to 24a of the first to fourth functional units 21 to 24. On the other hand, the communication hub 40 does not participate in the control of the control unit 34 of the remote controller 30 and the first to fourth control units 21a to 24a, for example.

  Note that at least one length D1 of the first wirings 51 to 54 is shorter than the length D2 of the second wiring 60, for example.

FIG. 4 is a block diagram illustrating a bathroom system according to the first embodiment.
As shown in FIG. 4, first wires 51 to 54 connecting the first to fourth control units 21 a to 24 a and the communication hub 40, and second wires connecting the communication hub 40 and the control unit 34 of the remote controller 30. Reference numeral 60 denotes a three-core cable. The three-core cable has, for example, two power lines 70 a and 70 b and one signal line 72. For example, the power supply line 70a is on the high potential side, and the power supply line 70b is on the low potential side (for example, ground).

  One of the first to fourth functional units 21 to 24 can supply power to the remote controller 30 through the communication hub 40. In this example, the first functional unit 21 supplies power to the remote controller 30 through the communication hub 40. The first functional unit 21 and the remote controller 30 are electrically connected. As a result, for example, DC 12V power is supplied from the first function unit 21 to the remote controller 30.

  On the other hand, the second to fourth functional units 22 to 24 and the remote controller 30 are electrically insulated. More specifically, insulating sections 48a to 48c are provided between the second to fourth functional units 22 to 24 and the remote controller 30. The insulating sections 48a to 48c are configured to be able to transmit and receive the signal S1 and the signal S2 in a state where the second to fourth functional units 22 to 24 and the remote controller 30 are electrically insulated.

  The insulating sections 48a to 48c have, for example, photocouplers. In this example, in order to perform bidirectional communication between the second to fourth functional units 22 to 24 and the remote controller 30, each of the insulating units 48a to 48c has two sets of photocouplers. Power is supplied from the first functional unit 21 to the light emitting element and the light receiving element on the remote controller 30 side of the two photocouplers via the first wiring 51. Of the two sets of photocouplers, the light emitting element and the light receiving element on the second to fourth function units 22 to 24 are supplied with power from the second to fourth function units 22 to 24 via the first wirings 52 to 54. Supplied. Thus, the signals S1 and S2 can be transmitted and received while the second to fourth functional units 22 to 24 and the remote controller 30 are electrically insulated.

  In the first embodiment, the first function unit 21 is a main function unit, and the second to fourth function units 22 to 24 are sub function units.

  Here, when the determining unit 80 determines that the power is “no”, the power determination information is transmitted to the control unit 34 of the remote controller 30.

Specifically, the determination unit 80 detects a voltage value (power supply value) supplied from the first function unit 21 to the remote controller 30. When the voltage value becomes equal to or less than a predetermined value, the determination unit 80 determines that the power supplied to the remote controller 30 is “absent”, and transmits the power determination information to the control unit 34 of the remote controller 30.
Note that the determination unit 80 may determine the presence or absence of a power supply by detecting a current value instead of a voltage value.

When receiving the power determination information from the determination unit 80, the control unit 34 of the remote control 30 transmits a stop signal to stop the operation to the second to fourth control units 22a to 24a of the second to fourth function units 22 to 24. . When the second to fourth control units 22a to 24a of the second to fourth function units 22 to 24 receive the stop signal, the operation of the operating second to fourth function units 22 to 24 is stopped.
As described above, when determining that the power supplied to the remote controller 30 is “absent”, the determining unit 80 stops the operations of the second to fourth function units 22 to 24 via the remote controller 30.

As described above, in the first embodiment, the first to fourth function units 21 to 24 (a plurality of function units) provided in at least one of the bathroom and the toilet, and the first to fourth functions are provided. A remote controller 30 for operating the units 21 to 24 and a determination unit 80 for determining whether or not power is supplied to the remote controller 30 are provided. The plurality of functional units are connected to the remote controller 30 by wire and supply power to the 30 remote controllers. A first function unit 21 (main function unit); and second to fourth function units 22 to 24 (sub function units) to which power is supplied from a location different from the first function unit 21, and a determination unit. 80 determines that the power supplied to the remote controller 30 is “absent”, and stops the operations of the second to fourth functional units 22 to 24 based on the power determination information. Let

Thus, for example, when the breaker of the first function unit 21 (main function unit) is turned off and the remote controller 30 becomes inoperable, the second to fourth function units 22 to 24 (sub function units) are automatically set. Since it can be stopped, useless power consumption can be suppressed.
In addition, when the remote controller 30 becomes inoperable, the user stops the second to fourth function units 22 to 24 (sub function units) by using a second function unit provided in the bathroom 100 or the washroom 110. Since it is not necessary to directly operate the fourth to fourth function units 22 to 24 (sub function units), it is convenient for the user.

In the first embodiment, when the power supply value from the first function unit 21 (main function unit) to the remote controller 30 falls below a predetermined value, the determination unit 80 determines that the power supplied to the remote controller 30 is “ No ".
Accordingly, the determination unit 80 can more accurately determine whether there is power to be supplied to the remote controller, and can further reduce unnecessary power consumption.

In the first embodiment, the determination unit 80 is provided on the remote controller 80.
Thus, it is not necessary to provide the determination unit 80 as a separate member, and wiring and the like of the bathroom system can be simplified.

  Next, a modified example of the bathroom system according to the first embodiment will be described. In the modified example, only the points changed from the first embodiment will be described, and the description of the common parts will be omitted.

  In a modified example of the bathroom system according to the first embodiment, the first control unit 21a of the first function unit 21 sends the signal S2 (signal about the operation state of the first function unit 21) to the control unit 34 of the remote control 30. Irrespective of the presence or absence of the signal S1 (control signal for operating the first functional unit 21) from the controller.

  Here, it is known that the state of the signal S2 transmitted from the first control unit 21a of the first function unit 21 becomes worse than normal when the power supply value supplied to the remote controller 30 decreases. I have.

The determining unit 80 detects the state of the signal S2 transmitted from the first function unit 21 to the remote controller 30, and determines that the power supplied to the remote controller 30 is “absent”.
Specifically, when the signal strength of signal S2 is equal to or less than a predetermined value, determination unit 80 determines that an abnormal state has been detected and determines that the power supplied to remote controller 30 is “absent”. Then, determination section 80 transmits the power supply determination information to control section 34 of remote controller 30.
The determining unit 80 may detect the abnormal state when the noise included in the signal S2 is equal to or more than a predetermined value, instead of detecting the abnormal state based on the signal strength.
Further, a dedicated signal for determining the presence / absence of power supplied to the remote controller 30 may be periodically transmitted from the first control unit 21 a of the first function unit 21 to the control unit 34 of the remote controller 30.

As described above, in the modification of the first embodiment, the determination unit 80 determines that the state of the signal S2 transmitted from the first function unit 21 (main function unit) to the remote controller 30 is abnormal. Is detected, it is determined that the power supplied to the remote controller 30 is “absent”.
Thus, the determination unit 80 can more accurately determine whether or not power is supplied, without being affected by noise or the like of the power supply itself, and can further reduce wasteful power consumption.

Next, a bathroom system according to a second embodiment will be described.
FIG. 5 is a block diagram illustrating a bathroom system according to the second embodiment. FIG. 6 is a block diagram illustrating a bathroom system according to the second embodiment.
In the second embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIGS. 5 and 6, the bathroom system 10 according to the second embodiment includes a determination unit 280.
The determination unit 280 is provided in the first function unit 21 and is connected to the first control unit 21a of the first function unit 21.
Note that the determination unit 280 may be provided separately from the first function unit 21 (mainly a unit) so that the breaker and the first function unit 21 are connected via the determination unit 280. It may be configured.

  Determination unit 280 determines whether there is power supplied to remote controller 30. When determining section 280 determines that the power supplied to remote controller 30 is “absent”, it stops the operation of second to fourth functional units 22 to 24 based on the power determination information.

Specifically, the determination unit 280 detects a voltage value (power supply value) supplied to the first function unit 21 from a breaker (not shown). When the voltage value becomes equal to or less than a predetermined value, the determination unit 280 determines that the power supplied to the remote controller 30 is “absent”, and transmits the power determination information to the first control unit 21 a of the first functional unit 21. I do.
Note that the determination unit 280 may detect the current value instead of the voltage value to determine the presence or absence of the power supply.
When the first control unit 21a of the first functional unit 21 receives the power determination information from the determination unit 280, the first control unit 21a transmits the power determination information to the control unit 34 of the remote controller 30.

When receiving the power determination information from the first control unit 21a of the first function unit 21, the control unit 34 of the remote control 30 operates the second to fourth control units 22a to 24a of the second to fourth function units 22 to 24. Send a stop signal to stop. When the second to fourth control units 22a to 24a of the second to fourth function units 22 to 24 receive the stop signal, the operation of the operating second to fourth function units 22 to 24 is stopped.
As described above, when the determination unit 280 determines that the power supplied to the remote controller 30 is “absent”, the operation of the second to fourth function units 22 to 24 via the first function unit 21 is stopped.

As described above, in the second embodiment, the determination unit 280 is supplied to the remote controller 30 when the power supply value supplied to the first function unit 21 (mainly a unit) falls below a predetermined value. Power supply is determined to be “No”.
Thus, before the power supply to the first functional unit 21 (mainly a unit) that supplies power to the remote controller 30 itself is completely cut off, the determination unit 280 can reliably determine the presence or absence of power supply. As a result, wasteful power consumption can be further suppressed.

In the second embodiment, the determination unit 280 is provided in the first functional unit 21 (mainly a unit).
Accordingly, it is not necessary to provide the determination unit 280 as a separate member, and wiring and the like of the bathroom system can be simplified.

Next, a bathroom system according to a third embodiment will be described. FIG. 7 is a block diagram illustrating a bathroom system according to the third embodiment. FIG. 8 is a block diagram illustrating a bathroom system according to the third embodiment.
In the third embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

  As shown in FIGS. 7 and 8, the bathroom system 10 according to the third embodiment includes a determination unit 380.

The determination unit 380 is provided in the second function unit 22 and is connected to the second control unit 22a of the second function unit 22.
Note that determination unit 380 may be provided independently of second function unit 22 (sub function unit), and remote controller 30 and second function unit 22 are connected via determination unit 380. May be configured.
In addition, the determination unit 380 is provided only in the second functional unit 22, but may be provided in the third to fourth functional units 22 to 24.

  This determination unit 380 determines whether there is power supplied to the remote controller 30. When determining that the power supplied to the remote controller 30 is “absent”, the determining unit 380 stops the operation of the second function unit 22 based on the power determination information.

Here, the control unit 34 of the remote controller 30 periodically transmits a signal S1 (a signal for confirming the operation state of the second function unit 22) to the second control unit 22a of the second function unit 21.
It is known that the state of the signal S21 transmitted from the remote controller 30 becomes worse than usual when the power supply value supplied to the remote controller 30 decreases.

When the signal strength of signal S1 is equal to or smaller than a predetermined value, determination unit 380 determines that an abnormal state has been detected and determines that the power supplied to remote controller 30 is “absent”. Then, the determination unit 380 transmits the power supply determination information to the second control unit 22a of the second function unit 22.
In other words, determination section 380 detects the state of signal S1 transmitted from remote controller 30 to second function unit 22, and determines whether there is power supplied to remote controller 30.
The determining unit 380 may determine the abnormal state when the noise included in the signal S1 is equal to or more than a predetermined value, instead of determining the abnormal state based on the signal strength.

When the second control unit 22a of the second functional unit 22 receives the power determination information from the determining unit 380, the operation of the operating second functional unit 22 stops.
As described above, when the determination unit 380 determines that the power supplied to the remote controller 30 is “absent”, the operation of the second function unit 22 is stopped via the second control unit 22a of the second function unit 22 itself. .

As described above, in the third embodiment, when the determination unit 380 detects that the state of the signal S1 transmitted from the remote controller 30 to the second function unit 22 (sub function unit) is an abnormal state, , The power supplied to the remote controller 30 is determined to be “absent”.
Accordingly, the determination unit 380 can more accurately determine whether or not power is supplied to the remote controller 30 without being affected by noise or the like of the power supply itself, and wasteful power consumption can be further suppressed.

In the third embodiment, the determination unit 380 is provided in the second function unit 22 (sub function unit).
Thereby, when the determination unit 380 determines that the power supplied to the remote controller 30 is “absent”, the second function unit 22 is controlled regardless of whether a stop signal is received from the remote controller 30 to the second function unit 22. It is possible to stop automatically, and wasteful power consumption can be further suppressed.
