Description

[Detailed Description of the Invention] This invention relates to a remote control device for an air conditioner, and particularly relates to a device for wirelessly and remotely controlling temperature control.

Generally, this type of home air conditioner is installed and fixed at a relatively high position on the indoor wall, so when controlling the operation of the air conditioner using wireless signals such as light, the transmitter sends signals at an elevation angle. Depending on the mounting position of the receiver, the signal may not reach the receiving circuit.

This invention has been made with this point in mind, and is intended to provide a highly reliable air conditioner control device that can accurately receive signals from a transmitter and control its operation.

This invention will be explained in detail with reference to the illustrated embodiments below.
Reference numeral 1 denotes the air conditioner main body, which is installed and fixed on a wall or the like in the room.

2 is a transmitter, and 3 is a receiver, which are constructed as shown in the block diagram shown in FIG. 2, and their operations are as follows.

That is, the temperature near the transmitter 2 is sensed by a temperature detection element 4 such as a thermistor, the temperature detection circuit 5 compares it with a set value, and depending on the result, either the large signal oscillation circuit 6 or the bright signal oscillation circuit 7 of the compressor is activated. is selected and the signal is transmitted by a transmitting element 8 such as a light emitting diode.

The signal transmitted from the transmitter 2 is received by a receiving element 9 such as a photodiode, and the signal is identified by a receiving circuit 10. If the signal is identified as a large signal, the switch 11 is driven and its contact 12 is closed. The compressor 13 is operated or stopped.

The receiving element 9 of the receiver is attached downwardly to the downwardly inclined portion 14 on the front surface of the air conditioner main body 1.

Therefore, by directing the transmitting element 8 of the transmitter at an elevation angle and transmitting a signal, the receiving element 9 mounted on the downwardly inclined part 14 on the front surface of the air conditioner main body 1 located at a high position will accurately catch this signal and control the operation. This is what we do.

As mentioned above, this idea has the light-receiving element for the receiver mounted on the downwardly sloping front part of the air conditioner body, and also consists of a transmitter that emits a signal in the elevation angle, so it can be placed in a high position. The receiving element on the front of the main body can accurately capture the wireless signal transmitted from below the main body, and the operation of the air conditioner can be reliably controlled.
