[Background of the invention]

In recent years, so-called home control systems, which centrally control electrical equipment in the home, have become a hot topic, and remote control of air conditioners that form part of the system, such as remote control of air conditioners in multiple rooms, has become a hot topic. Remote control of air conditioners from other rooms or from other rooms has been attracting particular attention.The first problem with such remote control from other rooms is that the air conditioners are located far away. Therefore, it is not known in what condition the air conditioner to be controlled is being operated.

In other words, it is not possible to recognize the operating mode, such as whether it is stopped or running, or the strength or weakness of its operation.

Therefore, it is difficult to know what kind of operation signal should be transmitted for remote control.

In addition, if a remote control device is to be adopted, it is desirable that it can be applied not only to newly installed models but also to existing models.

As for the remote control of conventional air conditioners, for example,
As described in Publication No. 0-93446, it is equipped with a remote controller connected by a cord, which operates mechanical switch mechanisms and control parts, and operates the mechanical control mechanism of the air conditioner body. I was supposed to let them do it.

Such a mechanical controller has a problem in that it cannot be applied to, for example, a microcomputer-controlled air conditioner in which the air conditioner to be controlled retains a control signal within an electronic circuit.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and allows initial settings to be made and remote control to be performed regardless of the operating mode of the air conditioner to be controlled. The purpose is to provide a remote control device for air conditioners that can also be applied to other systems.

[Summary of the Invention] The configuration of the remote control device for an air conditioner according to the present invention includes a remote control unit that transmits an operation signal at the hand of a remote operator, and a control target that receives the signal from the remote control unit. and a control signal output section that outputs control signals to the air conditioner, and the control signal output section is composed of a remote control signal transmission/reception section, a power supply switching device, and an operation signal output device. When operating the remote control operation unit, the output of the power supply switching device is cut off for a predetermined period of time to return the air conditioner to be controlled to the initial operation state, and then the output of the operation signal output device is used to shut down the air conditioner to be controlled. This system controls the operation of air conditioners.

Additionally, the idea behind developing the present invention is as follows.

For remote control, even if the operating mode of the air conditioner to be controlled in another room cannot be recognized, it is possible to turn off the power once.
When FF is applied, any type of air conditioner returns to the spinning state before the fourth operation. Once you have made the initial settings in this way, you will know what kind of signal should be output from the remote control operation section.

Focusing on this point, the remote control device for an air conditioner according to the present invention includes a remote control operation section and a control signal output section, and the control signal output section is combined with a power switchgear and an operation signal output device. This book is composed of a remote control signal transmitting and receiving device, and enables remote control of an air conditioner by first performing a reset operation on the air conditioner to be controlled using a power switch.
