FIG. 8 is a flowchart illustrating the energization cutoff process of the second overcurrent protection device 31B, 41B, 51B, 61B, 71B according to the embodiment.

First, the energization cutoff process of the first overcurrent protection device 21 will be described.

The first overcurrent protection device 21 detects the current flowing through the operating power supply unit 20 by the current detection unit 22 (S100). The first overcurrent protection device 21 determines whether or not the detected current is equal to or greater than the first threshold value (S101).

When the detected current is equal to or greater than the first threshold value (S101: Yes), the first overcurrent protection device 21 measures the time during which the current equal to or greater than the first threshold value is continuously flowing (S102).

The first overcurrent protection device 21 determines whether or not the measured time is equal to or longer than the first determination time (S103). When the measured time is shorter than the first determination time (S103: No), the first overcurrent protection device 21 returns to step S100 and continues the above process.

When the measured time is equal to or longer than the first determination time (S103: Yes), the first overcurrent protection device 21 opens the switch 23 (S104). As a result, the current flowing through the operating power supply unit 20, that is, all the bathroom-related devices 2 is cut off.

Next, the energization cutoff process of the second overcurrent protection device 31B, 41B, 51B, 61B, 71B will be described. Here, the energization cutoff process in the bathroom cleaning device 10 will be described as an example, but the energization cutoff process in the automatic drain plug 11 and the like is also the same.

The second overcurrent protection device 31B detects the current flowing through the power control unit 31A by the current detection unit 32 (S200). The second overcurrent protection device 31B determines whether or not the detected current is equal to or greater than the second threshold value (S201).

When the detected current is equal to or greater than the second threshold value (S201: Yes), the second overcurrent protection device 31B measures the time during which the current equal to or greater than the second threshold value is continuously flowing (S202).

The second overcurrent protection device 31B determines whether or not the measured time is equal to or longer than the second determination time (S203). When the measured time is shorter than the second determination time (S203: No), the second overcurrent protection device 31B returns to step S200 and continues the above process.

The second overcurrent protection device 31B opens the switch 33 (S204) when the measured time is equal to or longer than the second determination time (S203: Yes). As a result, the current flowing through the power control unit 31A, that is, the bathroom cleaning device 10 is cut off. The second threshold value is smaller than the first threshold value, and the second determination time is shorter than the first determination time. Therefore, when an overcurrent flows through the bathroom cleaning device 10, the second overcurrent protection device 31B cuts off the energization of the bathroom cleaning device 10 before the first overcurrent protection device 21. In this case, the energization of the bathroom-related equipment 2 other than the bathroom cleaning device 10 is not cut off. Therefore, the bathroom-related equipment 2 other than the bathroom cleaning device 10 can be used.

When the detected current is smaller than the second threshold value (S201: No), the second overcurrent protection device 31B resets the measured time (S205).

Next, the effect in the bathroom equipment system 1 will be described.

The bathroom equipment system 1 includes a plurality of bathroom-related equipment 2, an operation power supply unit 20, a plurality of power control units 31A, 41A, 51A, 61A, 71A, a first overcurrent protection device 21, and a plurality of second units.

The operating power supply unit 20 generates operating power for operating a plurality of bathroom-related devices 2 from AC power supplied via a distribution board 110 provided in a house. The plurality of power control units 31A, 41A, 51A, 61A, 71A control the operating power supplied from the operating power supply unit 20 for each of the plurality of bathroom-related devices 2. The first overcurrent protection device 21 can cut off the energization of the operating power supply unit 20 when an overcurrent flows through the operating power supply unit 20. The plurality of second overcurrent protection devices 31B, 41B, 51B, 61B, 71B are provided between the plurality of bathroom-related devices 2 and the operating power supply unit 20, and energize the plurality of bathroom-related devices 2, respectively. It can be blocked. The plurality of second overcurrent protection devices 31B, 41B, 51B, 61B, 71B are bathrooms in which an overcurrent flows before the first overcurrent protection device 21 when an overcurrent flows through the bathroom-related device 2. Cut off the power supply to the related device 2.

As a result, only the energization of the bathroom-related device 2 through which the overcurrent has flowed is cut off, and the bathroom-related device 2 in which the overcurrent has not flowed can be used. That is, the bathroom equipment system 1 can suppress the stoppage of the operation of the bathroom-related equipment 2 other than the bathroom-related equipment 2 through which the overcurrent has flowed.

For example, when an overcurrent flows through the equipment provided in the bathroom 100, the communication device 14 in which the overcurrent does not flow can be used. In this case, for example, the user can acquire information about the device in which the overcurrent has flowed from outside the house by the terminal device 6, and can quickly take measures against the failure of the device provided in the bathroom 100.

An overcurrent protection device using a fuse can secure a sufficient margin between the fusing current when an overcurrent flows and the steady current, and the threshold value (first threshold value, or first threshold value) of another overcurrent protection device. It is an overcurrent protection device that can sufficiently secure the difference between (2 threshold values) and the steady current. An overcurrent protection device in which a fuse is used is an overcurrent protection device having a steady current that does not blow the fuse due to a product error of the fuse.

As a result, the bathroom equipment system 1 according to the modified example can reduce the cost of the overcurrent protection device.

The bathroom equipment system 1 according to the modified example has a current lower than the second threshold value when a current equal to or higher than the second threshold value flows in the second overcurrent protection devices 31B, 41B, 51B, 61B, 71B for the second determination time or longer. The current limiting unit for limiting may be provided in the second overcurrent protection device 31B, 41B, 51B, 61B, 71B. The current limiting unit may be provided in any one or more of the second overcurrent protection devices 31B, 41B, 51B, 61B, and 71B.

As a result, the bathroom equipment system 1 according to the modified example supplies power to the bathroom-related equipment 2 again when, for example, the cause of the overcurrent being generated in the bathroom-related equipment 2 through which the overcurrent has flowed is eliminated. can do. For example, when an overcurrent flows in the bathroom cleaning device 10 and the cause of the overcurrent is eliminated, the bathroom cleaning device 10 can be used again.

In the bathroom equipment system 1 according to the modified example, when the current of the second threshold value or more flows in the second overcurrent protection device 31B, 41B, 51B, 61B, 71B for the second determination time or more, the first overcurrent protection device 21 You may temporarily prevent the switch 23 from turning off. As a result, it is possible to prevent the switch 23 of the first overcurrent protection device 21 from being turned off due to the occurrence of overcurrent in the second overcurrent protection devices 31B, 41B, 51B, 61B, 71B.

In the bathroom equipment system 1 according to the modified example, the second overcurrent protection devices 31B, 41B, 51B, 61B, 71B may be provided separately from the bathroom-related equipment 2. For example, in the bathroom equipment system 1 according to the modified example, at least one of the second overcurrent protection devices 31B, 41B, 51B, 61B, 71B may be provided in the communication box 4. Further, the bathroom equipment system 1 according to the modified example may be integrally provided with a plurality of second overcurrent protection devices 31B, 41B, 51B, 61B, 71B.

As a result, the bathroom equipment system 1 according to the modified example can reduce the space in which the bathroom-related equipment 2 is arranged. For example, in the bathroom equipment system 1 according to the modified example, the power control boxes 31, 41, and 51 can be miniaturized, and the space behind the ceiling can be effectively utilized. Further, for example, the operator can easily construct the power control boxes 31, 41, 51.

Further, the bathroom equipment system 1 according to the modified example may be provided with equipment such as a bathroom dryer / heater. Further, the bathroom equipment system 1 according to the modified example may be a system in which a part of the bathroom-related equipment 2 is not provided. Further, in the bathroom equipment system 1 according to the modified example, the bathroom-related equipment 2 may be connected to the power supply box 3 without going through the communication box 4.
