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

A control unit 34 of the remote controller 30 is connected to the operation unit 32 and the display unit 36 of the remote controller 30 . When the user operates the operation unit 32 of the remote controller 30, a signal S1 is transmitted from the controller 34 of the remote controller 30 to the first to fourth controllers 21a to 24a of the first to fourth functional units 21 to 24. be done. The signal S1 includes a control signal for at least one of the first to fourth controllers 21a to 24a. Signal S1 is a common control signal.

The signal S1 is transmitted through the communication hub 40 to each of the first to fourth controllers 21a to 24a. In other words, for example, a control signal for the first control unit 21a (a control signal for operating the first functional unit 21) is sent not only to the first control unit 21a but also to the second to fourth control units 22a to 24a. is also sent. The first to fourth control units 21a to 24a respectively control the operations of the first to fourth functional units 21 to 24 according to the signal S1.

At this time, for example, each of the first to fourth controllers 21a to 24a determines whether or not the signal S1 includes a control signal for operating the functional unit it controls. 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 functional unit 21, and 21 is activated. On the other hand, the second to fourth control units 22a to 24a determine that the signal S1 does not include a control signal for operating the second to fourth functional units 22 to 24, and the second to fourth functional units 22a to 24a Do not operate ~24.

Also, 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 about the operating state of at least one of the first to fourth functional units 21-24.

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

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

Note that the length D1 of at least one 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 the bathroom system according to the embodiment.
As shown in FIG. 4, first wirings 51 to 54 connecting the first to fourth control units 21a to 24a and the communication hub 40, and second wirings connecting the communication hub 40 and the control unit 34 of the remote controller 30. 60 is a three-core cable. A three-core cable has, for example, two power lines 70 a and 70 b and one signal line 72 . For example, the power line 70a is on the high potential side and the power line 70b is on the low potential side (eg, 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 control 30 through the communication hub 40 . The first functional unit 21 and the remote controller 30 are electrically connected. As a result, power of DC 12 V, for example, is supplied from the first functional unit 21 to the remote controller 30 .

On the other hand, the second to fourth functional units 22 to 24 and the remote control 30 are electrically insulated. More specifically, insulating portions 48a to 48c are provided between the second to fourth functional units 22 to 24 and the remote control 30, respectively. The insulating units 48a to 48c are configured to enable transmission and reception of the signals S1 and S2 while electrically insulating the second to fourth functional units 22 to 24 and the remote control 30 from each other.

The insulating parts 48a to 48c have photocouplers, for example. In this example, each of the insulators 48a-48c has two sets of photocouplers for bi-directional communication between the second to fourth functional units 22-24 and the remote control 30. FIG. Power is supplied from the first functional unit 21 through the first wiring 51 to the light-emitting element and the light-receiving element on the remote control 30 side of the two photocouplers. Power is supplied from the second to fourth functional units 22 to 24 through the first wirings 52 to 54 to the light emitting elements and light receiving elements on the second to fourth functional units 22 to 24 sides of the two sets of photocouplers. supplied. As a result, the signal S1 and the signal S2 can be transmitted and received while the second to fourth functional units 22 to 24 and the remote control 30 are electrically insulated.

In this embodiment, the first to fourth functional units 21 to 24 and the remote controller 30 are connected by the first wirings 51 to 54 and the second wiring 60 via the communication hub 40. The first to fourth functional units 21 to 24 and the remote controller 30 may be connected by wiring without the hub 40 intervening.
In this case as well, the signal S1 and the signal S2 can be transmitted and received while the first functional unit 21 and the remote control 30 are electrically connected. On the other hand, 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 isolated.

Here, in this embodiment, the first functional unit 21 is the main functional unit, and the second to fourth functional units 22 to 24 are sub-functional units.
When the second to fourth control units 22a to 24a of the second to fourth functional units 22 to 24 receive a control signal (operating start signal) for starting operation of the functional units from the remote controller 30, the second to fourth controllers 22a to 24a control the functions of the remote controller 30. Only the automatic stop operation is performed, in which the operation is started based on a control signal (operation start signal) for starting the operation of the unit, and the operation is stopped after a predetermined time has elapsed from the start of the operation. That is, the second to fourth functional units 22 to 24 (sub-functional units) operate regardless of whether or not a control signal (operation stop signal) for stopping the operation of the functional units is received from the remote controller 30 during operation. Always stop after a predetermined time has elapsed from the start. Details of the control will be described later.

Next, the operation of the sub-functional unit will be described with reference to FIG.
FIG. 5 is a flow chart showing the operation of the sub-functional units.
Although FIG. 5 shows the operation of the fourth functional unit 24 that does not supply power to the remote controller 30, the second functional unit 22 and the third functional unit 23 that do not supply power to the remote controller 30 operate similarly. to run.

First, in processing D1, upon receiving an operation start signal from the remote controller 30, the fourth control section 24a causes the fourth functional unit 24 to start operating. Then, in process D2, the fourth control unit 24a starts measuring time t from the start of operation of the fourth functional unit 24, and proceeds to process D3.

Next, in process D3, the fourth control section 24a determines whether or not a control signal for operating the fourth functional unit 24 has been received from the remote controller 30 after operation has started.

In processing D3, if a control signal for operating the fourth functional unit 24 is received from the remote controller 30 (processing D3, Yes), the fourth control unit 24a resets time t in processing D4, and resets time t. start measuring again. After executing the process D4, the fourth control unit 24a returns to the process D3.

On the other hand, if the control signal for operating the fourth functional unit 24 is not received from the remote controller 30 in the process D3 (process D3, No), the fourth control unit 24a performs the fourth functional unit 24 compares the time t and the specified time T in order to confirm whether a predetermined time has passed since the start of operation.
The specified time T is set to 2 to 3 hours and stored in the fourth control section 24a.

In process D5, if time t≧prescribed time T (process D5, Yes), the fourth control unit 24a executes process D6.
On the other hand, in process D5, if time t<prescribed time T (process D5, No), the fourth control unit 24a returns to process D3 and executes the process.

In process D6, the fourth controller 24a causes the fourth functional unit 24 to stop operating. Then, the process proceeds to process D7, and the operation process of the automatic stop operation in the fourth control unit 24a ends.

In this manner, the fourth functional unit 24 starts operation based on the operation start signal from the remote controller 30, and performs only the automatic stop operation in which the operation is stopped after a predetermined time has elapsed from the start of operation.
Note that the automatic stop operation that stops after a predetermined time has elapsed from the start of operation may be such that the operation automatically stops when a series of predetermined operations from the start of operation is completed.

As described above, in the embodiment, the second to fourth functional units 22 to 24 (sub-functional units) start operating based on the operation start signal of the remote controller 30, and after a predetermined time has elapsed from the start of operation, Execute only automatic stop operation to stop. As a result, for example, even if the breaker of the first functional unit 21 (main functional unit) is tripped and the remote controller becomes inoperable, the second to fourth functional units 22 to 24 (sub-functional units) will still operate. Wasteful power consumption can be suppressed because the operation is always stopped after a predetermined period of time from the start.
In addition, in order to stop the second to fourth functional units 22 to 24 (sub-functional units) when the remote control 30 becomes inoperable, the user operates the second to fourth functional units provided in the bathroom or washroom. Since there is no need to directly operate the four functional units 22 to 24 (sub-functional units), it is convenient for the user.

Further, in the embodiment, the second to fourth functional units 22 to 24 (sub-functional units) reset the count of the predetermined time when receiving the control signal from the remote controller 30 during the automatic stop operation. As a result, for example, when the user changes the settings of the second to fourth functional units 22 to 24 (sub functional units) after starting operation, the predetermined time count is reset and restarted. Therefore, it is possible to prevent the second to fourth functional units 22 to 24 (sub-functional units) from stopping immediately after the setting change by the user. Easy to use for people.

Also, in the embodiment, the fourth functional unit 24 (sub-functional unit) has a heating function. According to this, the heating function consumes a large amount of power. Therefore, by always stopping the operation after a predetermined period of time from the start of the operation, it is possible to significantly reduce the power consumption.

Also, in the embodiment, the second functional unit 22 (sub-functional unit) has a cleaning function. As a result, the cleaning function is always stopped after a predetermined period of time from the start of operation, so that wasteful power consumption can be suppressed.

In this embodiment, for example, DC 12V power is supplied from any one of the second to fourth functional units 22 to 24 to the remote controller 30, and the first functional unit 21 and the remaining second to fourth functional units are supplied. 22 to 24 and remote control 30 may be electrically insulated.
In that case, any one of the second to fourth functional units 22 to 24 that supplies DC 12V power to the remote control 30 is the main functional unit, and the first functional unit 21 and the remaining second to fourth functional units 22 to 24 are the main functional units. 24 are sub-functional units.
Here, the ventilation function is often operated for a long time, and the user tends to forget to stop it.
If the first functional unit 21 (sub-functional unit) is a bathroom air conditioner and has a ventilation function for ventilating the inside of the bathroom 100, even if the user forgets to stop the first functional unit 21 Since the (sub-functional unit) stops after a predetermined period of time, the ventilation function does not continue more than necessary, which is convenient for the user.
