[0002]

2. Description of the Related Art In recent years, wireless remote controllers have been used for operation control of ceiling fans.

Conventionally, this type of ceiling fan has a configuration as shown in FIGS. As shown in the figure, a mounting bracket 101 is mounted on a ceiling surface, and a main body 102 is supported by the mounting bracket 101. An optical receiver 103 is provided on an upper side surface of the main body 102, receives a signal from a remote operation device 104, and controls a rotation of an electric motor 107 having a blade 106 by a control device 105 for determining a received signal.

[0004]

In such a conventional ceiling fan, when the illuminator is located near the ceiling fan, the light from the illuminator interferes with the light receiver, and the signal from the remote control device is transmitted. There was a problem that reception was not possible.

In addition, it is difficult to relocate either the ceiling fan or the illuminator so as not to be disturbed by the illuminator, when the wiring work is difficult to change, or when the layout of the room is changed, so that the relocation is not easy. There was a problem that.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem, and it is an object of the present invention to provide an optical device capable of receiving an optical signal without being interrupted by light of an illuminator when the illuminator is located near an optical receiver of a ceiling fan. This is the purpose of 1.

A second object of the present invention is to share components of a remote control device and receive signals in a low cost and easily in response to interference from an illuminator.

[0008]

A first means for achieving the first object of the present invention is a main body having a motor mounted on a ceiling, a blade radially mounted on the motor, and the main body. An optical receiver for receiving an optical signal, a control board for receiving the signal from the optical receiver and controlling the rotation of the electric motor, and a remote control device for wirelessly transmitting the optical signal to the optical receiver. The remote control device is configured to be connectable to the control board by a connection line.

A second means for achieving the second object is that a main body having an electric motor mounted on a ceiling, blades radially mounted on the electric motor, and an optical signal from the outside of the main body. An optical receiver provided in the main body for receiving, a control board for inputting a signal from the optical receiver and controlling the rotation of the electric motor, and a remote control device for wirelessly transmitting an optical signal to the optical receiver, The remote control device has an optical transmission unit detachably provided, the separated optical transmission unit is provided near the optical receiver of the main body, and the optical transmission unit and the remote operation device without the optical transmission unit are connected by a connection line. It is configured to be connected by.

[0010]

According to the structure of the first means of the present invention, when there is an illuminator near the ceiling fan, the remote control device and the control board of the main body are connected by a connection wire, so that the connection wire is connected from the remote control device. Signal is sent directly to the control board of the main unit via
It can be transmitted and received without interference from the illuminator.

Further, according to the configuration of the second means, the separated optical transmitter of the remote control device is attached to the vicinity of the optical receiver of the main body, and the signal is transmitted through the connection line, thereby using the wireless system. It can be used effectively even in the case of the wired system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. The same components as those of the conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in the figure, a photo isolator 3 is connected to a control board 2 of a main body 1 in parallel with an optical receiver 103, and a connector 4 is provided on the input side of the photo isolator 3. The remote control device 5 includes an optical transmitter 6 and a connector 7 in parallel with the optical transmitter 6. By connecting the connector 4 and the connector 7 with a connection line 8, a signal can be transmitted as a wired system.

In the above configuration, during normal use, by operating the remote controller 5, an optical signal is transmitted from the optical transmitter 6 to the optical receiver 103 in a wireless manner, and is controlled by the control board 2 in the main body 1. The operation of the electric motor 106 is controlled.

However, when the illuminator 9 is located near the main body 1 of the ceiling fan, the connector 4 of the main body 1 and the remote control 5
Of the remote control device 5 can be directly transmitted to the control board 2 of the main body, thereby avoiding interference of the optical signal to the optical receiver 103 of the illuminator 9. And can be operated accurately.

The photo isolator 3 provided on the control board 2 can transmit a signal from the remote operation device 5 to the control board 2 in the wired system by converting an electric signal into an optical signal on the way. Is responsible for maintaining electrical insulation so that it can operate as an independent circuit system.

As described above, according to the ceiling fan of the first embodiment of the present invention, the remote control device and the ceiling fan, which are usually used as a wireless system, can be connected to each other by a connection line so that they can be operated. When the influence of light from the illuminator is large, a wired system can be used.

Next, a second embodiment of the present invention will be described with reference to FIGS. As shown in the figure, an optical transmitter 11 located at the tip of the remote control device 10 is detachably attached via connectors 12 and 13.
When the illuminator 9 is located near the optical receiver 103 of the main body 1, the optical transmitter 11 is detached from the remote control device 10 and attached near the optical receiver 103 of the main body 1.
The connection line 8 is arranged and connected between the connector 12 and the connector 13, and the remote control device 5 and the optical transmission unit 11 are connected.

Accordingly, the operation signal from the remote control device 10 enters the optical receiver 103 at a short distance from the optical transmitter 11 via the connection line 8 and is transmitted accurately without being affected by the illuminator 9.

As described above, according to the ceiling fan of the second embodiment of the present invention, when changing from the wireless system to the wired system in order to avoid interference with the illuminator, the optical transmitter is separated from the remote control device, Furthermore, since it can be installed and used on the main body side, the number of additional parts can be reduced, and the wired system can be easily realized at low cost.

[0021]

As is clear from the above embodiments, according to the present invention, when there is an interference with an optical signal from an illuminator or the like near a ceiling fan, a remote control device normally used as a wireless system is used. By changing the control of the ceiling fan to a wired system by connecting a connection line to the cable, the optical signal from the remote control device can be received without interference. Also, by separating the parts of the remote control device used in the wireless system when using the wired system and using it on the ceiling fan body side, the wired system can be realized easily and inexpensively by reducing additional parts. Ceiling fan can be provided.
