Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a wireless remote control device for an air conditioner.

2. Description of the Related Art In general, a wireless remote controller/1/ (hereinafter referred to as a wireless remote control) device for an air conditioner (hereinafter referred to as an air conditioner) is installed on the front side 2 of an air conditioner 21, as shown in FIG.
2 is provided with a suction part 23 and a blow-out part 24, and a reception part 25, and a wireless remote control 28 is set to operate 0N10F.
An F switch 26, a thermosetting switch 27, etc. are provided to operate the air conditioner 21, thermosetting, etc. The air conditioner 21 is configured to receive an infrared operation signal transmitted from the transmitter 29 of the wireless remote controller 28 and operate the air conditioner 21.

Inputting operation signals to the main body control unit (not shown) of the air conditioner 21 in the above example is carried out through the input circuit 31, as shown in FIG. When the items are input, the remote control microcomputer 32 connected to this input circuit 31 converts these operation items into serial signals (codes) and outputs them to the transmitting circuit 33 connected to this remote control microcomputer 32. Then, it is transmitted from the transmitting circuit 33 as an infrared transmission wave. This transmitted infrared transmission wave is received by a receiving circuit 34, and this receiving circuit 34 is connected to a main body control microcomputer 36.
The operation items were input to the main body control microcomputer 35 to control the equipment.

Problems to be Solved by the Invention In such a conventional configuration, if there is something that blocks infrared transmission waves between the receiving section 26 and the transmitting section 29, the receiving section 26
Infrared transmission waves no longer reach the wireless remote control 2.
The device does not operate even if you operate 8. Therefore, the wireless remote control 28 must be installed in a place where it can receive signals, but if the room is dogleg-shaped or the air conditioner 21 is installed in a built-in corner of the room, the wireless remote control 28 must be installed in a corner of the room. There are many places where infrared transmission waves cannot reach, and installation locations are restricted, making it difficult to use. The present invention takes into account the above-mentioned conventional problems, and enables the installation of a wireless remote control 28 that is flexible in installation without being affected by the shape of the room or the form of the air conditioner.
The object of the present invention is to provide a wire remote control device.

Means for Solving the Problems In order to solve the problems, the present invention provides a wireless remote control equipped with an input circuit for each operation, a remote control microcomputer, a transmission circuit for transmitting data to a relay device, The relay device has a receiving circuit that outputs a response, a microcomputer that outputs a response, and a transmitting circuit that transmits to the air conditioner, and controls the air conditioner body through the receiving circuit of the air conditioner that receives input from the transmitting circuit of the relay device. The device is equipped with a main unit control microcomputer that performs the following functions.

Function: With this configuration, the transmitting circuit of the wireless remote controller outputs to the receiving circuit of the relay device, the transmitting circuit of the relay device outputs to the receiving circuit of the air conditioner, and the air conditioner is controlled by the main control microcomputer of the air conditioner. will be carried out.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 1, for example, cooling, thermo setting 21
The remote control microcomputer includes an input circuit 1 for inputting operation items of the air conditioner such as temperature and high airflow, a remote control microcomputer 2 connected to this input circuit 1, and a transmitting circuit 3 for transmitting the output from the remote control microcomputer 2. The infrared transmission wave a5 transmitted from the transmitting circuit 3 connected to the wireless remote control 4 is connected to the receiving circuit 6 on the input side and the transmitting circuit 7 on the output side. The data is composed of a microcomputer 8 that changes the data code as it is and outputs it with a certain degree of response, and is received by the receiving circuit 6 of an independent relay device 9. The infrared transmission wave b10 transmitted from the transmitting circuit 7 is received by a receiving circuit 12 connected to the input side of a main body side leg microcomputer 11 provided in the air conditioner main body. Note that the infrared transmission wave a5 and the infrared transmission wave b1o are, for example, serial signals,
A transmission wave code for classifying the transmission waves is provided at the beginning of the code system, and if this transmission wave code does not match a code preset in the microcomputer, the microcomputer uses software to ignore the received signal.

A wireless remote control device having the circuit configuration as described above can be used, for example, as shown in FIG.
When the wireless remote controller 4 is installed in a place where it can be operated most easily, the wall 16
The relay device 9 is installed in a place where there are no obstacles between the wireless remote controller 4 and the air conditioner 14.

In the above configuration, when the user operates the wireless remote control 4, the signal is once relayed by the relay device 9 and reaches the receiving circuit 12 on the main body side from the transmitting circuit 7 of the relay device 9. The air conditioner 14 will operate without being affected.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention allows infrared transmission waves transmitted to the wireless remote controller by the relay device to reach the receiving section of the main body by avoiding obstacles. This has the effect that there are fewer restrictions on the installation location of the wireless remote controller and that it is easier to use. Also, depending on the installation location, the wireless remote control may be removed and used. In this case, the signal from the relay device and the wireless remote control will reach the receiving section of the main unit, but since the response is provided, there will be no interference and no interference. does not occur. Note that this relay device has extremely wide applicability, as it is possible to provide two relay points to provide two relay points.
