Abstract

PURPOSE:To make the control unaffected by mutual situations or the like in which remote controllers of the wireless and wired types are installed and enable efficiently setting the operation by providing an air conditioner with a signal-selecting part to which respective signals from the wireless and wired remote controls are inputted and from which relevant signals are outputted to an air conditioner-controlling part. CONSTITUTION:When details of the operation of an air conditioner 1 are set by the control part 8a of a wireless remote control 8, an optical signal transmitter 9 converts signals representing the details of the operation to optical signals, such as signals of infrared rays, and transmits the converted signals to a receiver 5 at the air conditioner. The receiver 5 at the air conditioner reconverts the optical signals to electrical signals and sends the reconverted signals to an air conditioner-controlling part 3 through a signal-selecting part 4. The air conditioner-controlling part 3 transmits to an output circuit 2 signals based upon the inputted set details of the operation and a predetermined program so that, through actuation of relays, and the like, the air conditioner 1 is put in action accordingly. On the other hand, when details of the operation are set by the control part 10a of a wired remote control 7, electrical signals representing the details of the operation are sent from a signal transmitter 10 to the signal-selecting part 4.

Next, the operation will be explained. Wired remote control section (7
When the operating details of the air conditioner are set using the operation unit (IDa) K in a), the operating details converted into electrical signals by the transmitting unit αIK are sent to the wireless remote control unit 18) via the signal line (6). The signal is transmitted and output to the receiving unit [+11. The operation details based on the Beki signal received by the receiving unit at+ are sent to the signal transmitting unit (9
) is converted into an optical signal such as infrared rays and sent to the main body receiving section (5) of the air conditioner (1). The main unit receiver (5) converts the unreceived operation details into electrical signals again and sends them to the main unit control unit (3).
). The main body control unit (3) uses the received operation settings and predetermined program.
The output circuit (2) consisting of relays etc. is operated to operate each part of the air conditioner (1).

When the operation details are set using the operation section (8a) in the wireless remote control section (8), the signal transmission section (9) converts it into an optical signal and sends it to the main body reception section (5). Thereafter, as described above, the main body control section (3) sends a signal to the output circuit (2) based on the signal from the main body receiving section (5) to operate each part of the air conditioner (1).

[Problem to be solved by the invention]

Conventional air conditioner control devices were configured as described above, so in order to send signals to the air conditioner, it must be done through wireless signals such as light, and remote control devices that transmit optical signals are It must be placed in a place where it can reliably send signals to the main unit. Another problem is that the remote control device that sends optical signals has an electric wire connecting it to other remote control devices.

This invention was made in order to solve the above-mentioned problems.A remote control device that transmits optical signals can be carried freely, and a remote control device that transmits optical signals can be easily carried around compared to other remote control devices. To provide a control device for an air conditioner that can reliably perform operation settings no matter where it is placed.

[Means to solve the problem]

The air conditioner control device according to the present invention includes a signal selection section upstream of the main body control section, so that the signal from the wired remote control section via electric wires is directly input to the main body, and remote control is performed using wireless signals such as light. The two sections are set up together.

[Effect]

In the air conditioner control device according to the present invention, an optical signal is inputted through the main body receiving section, and a signal from the electric wire is directly inputted to the signal selection section, and the signal is sent from the signal selection section to the main body control section.

〔Example〕

An embodiment of the invention will now be described with reference to the drawings. 1st
In the figure, (1) is an air conditioner, (2) is an output circuit that operates each part of the air conditioner, and (3) is an air conditioner (1).
) is connected to the output circuit (2) at the main body control section that controls the operation of the main unit. (4) is a signal selection section and is connected to a wired remote control section 17)K which is connected to the main body reception section 9 (5) through a signal line f61K. (8) consists of a wireless remote control unit, a signal transmitting unit 19) that transmits optical signals such as infrared rays to the main unit receiving unit 15), and an operation unit (8a) that performs operation settings for the main unit (1). There is. Port 1 is a signal transmitting section provided in the wired remote control section (71), and an operating section (IOa) is provided on one side of the control section.

Next, the operation will be explained. Wireless far-field control unit (

Then, the main body receiving section (5) converts the sent optical signal into an electrical signal again and sends it to the main body control section (3)K through the signal selection section (4). The main body control section (3) sends a signal to the output circuit (2) according to the input operation settings and a predetermined program to operate a relay or the like to operate the air conditioner f1).

On the other hand, the operation unit (IOa) of the wired remote control unit (7)
If the operation details are set by 9, the signal transmitter α1
The signal is sent to the signal selection section (4) as a 1-ki signal.

Then, the signal selection section (4) selects the input signal from the main body control section (
3) The main body controller 13) operates the air conditioner fl) by operating the output circuit 12).

Note that in the above embodiment, one part is an optical signal and the other part is an electric wire type remote control part, but instead of the electric wire type remote control part, a remote control part using an optical signal and an external part are installed in a place where they do not interfere with each other. A similar effect can be obtained by providing an optical signal receiving section.
