## Abstract

A remote control device according to an embodiment includes an operation button, a generator, an electrical storage part, electronic paper, and a controller. The operation button is for remotely operating a wet-area device. The generator generates electrical power by utilizing energy when the operation button is pressed. The electrical storage part stores the electrical power. The electronic paper displays a setting state of the wet-area device. The controller controls a display-switching of the electronic paper and a transmission of a signal to remotely operate the wet-area device. The operation button is for modifying the setting state. The controller performs the display-switching and the transmission of the signal by utilizing the electrical power stored in the electrical storage part. The controller performs the display-switching after the transmission of the signal when the operation button is pressed.

## Claims

### Claim 1

A remote control device, comprising:
an operation button for remotely operating a wet-area device;
a generator generating electrical power by utilizing energy when the operation button is pressed;
an electrical storage part storing the electrical power;
electronic paper displaying a setting state of the wet-area device; and
a controller controlling a display-switching of the electronic paper and a transmission of a signal to remotely operate the wet-area device,
the operation button being for modifying the setting state,
the controller performing the display-switching and the transmission of the signal by utilizing the electrical power stored in the electrical storage part,
the controller performing the display-switching after the transmission of the signal when the operation button is pressed.

### Claim 2 (depends on 1)

The remote control device according to claim 1, wherein the controller transmits the signal again by utilizing the electrical power stored in the electrical storage part after the display-switching is performed.

### Claim 3 (depends on 1)

The remote control device according to claim 1, further comprising a memory part storing the setting state,
the controller switching a display of the electronic paper to another setting state after the modifying when the operation button is pressed, and storing the other setting state in the memory part after the switching.

### Claim 4 (depends on 3)

The remote control device according to claim 3, wherein in the display-switching, the controller causes the electronic paper to display the other setting state formed by the setting state stored in the memory part being modified by the operation button.

### Claim 5 (depends on 1)

A wet-area system, comprising:
the remote control device according to claim 1; and
the wet-area device receiving the signal,
in the case where a setting state stored in the wet-area device is different from a setting state included in the signal, the wet-area device determines the setting state of the wet-area device based on the setting state included in the signal.
