Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for an air conditioner.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for a remote control device for an air conditioner that can be used with either a wireless type or a wired type when remotely controlling an air conditioner.

A conventional remote control device for an air conditioner will be described with reference to FIG. As shown in the figure,
The indoor unit 21 was connected to the receiving section 24 that receives a signal from the infrared light transmitting LED 23 of the wireless remote controller 22 and the other end of the cable 26, one end of which is connected to the wired remote controller 25.

The wireless remote controller 22 is driven by a battery so that the signal from the infrared light transmitting LED 23 is transmitted to the indoor unit 21.
It was one way to send to.

Further, the wired remote controller 25 has been commercialized with the cable 26 having a fixed length connected thereto. When the indoor unit 21 has a failure diagnosis function, the display is performed on the indoor unit 21 side, and a display circuit dedicated to the failure display is used.

The operation monitor with the wireless remote controller 22 cannot be displayed without the operation monitor information from the indoor unit 21, and is generally driven by a battery, and a large current consumption display such as a display LED. No means were used.

Further, if the rechargeable battery is rarely used in the wireless remote controller 22 and the battery consumption is large even if it is used, battery replacement and recharging are required.

Further, as disclosed in Japanese Patent Laid-Open No. 3-122443, a wireless remote control device for setting the operation content of an air conditioner by a signal such as light is connected to a wireless remote control device by a signal line to set the operation content by an electric signal. In some cases, two remote control units of the wired remote control device were independently used to send a signal to the main body control unit.

[0009]

A wireless remote controller 2 in such a conventional remote control device for an air conditioner.
In the case of No. 2, not only the reachable range and the range are narrowed due to battery consumption, but also the wireless remote controller 22 itself may be lost.

In many cases, the wireless remote controller 22 is used by being attached to a wall near the indoor unit 21, and even if the battery is new, it may be operable depending on the installation location. .

In the case of the wired remote controller 25, since the cable 26 of a fixed length is connected, when the cable 26 is attached with a short length, the cable 26 may be pushed into the back side of the indoor unit 21 or may be left in a ring shape and exposed. In many cases, the cable 26 could not be treated properly.

Further, there are many requests from users to freely change the wireless remote controller 22 to a wired type, and it has been desired to change the wireless remote controller 22 by a simple operation. And, when it has a failure diagnosis function, it is necessary to display the details of the failure by numbers or characters, and for that purpose, it is necessary to provide a dedicated display section, which causes design restrictions.
If the display unit has a two-digit or three-digit display, problems will occur in cost and circuit power supply capacity.

Also, in the display of the wireless remote controller 22, it is desired to provide an easy-to-understand display capable of distinguishing whether the air conditioner is currently operating or stopped. However, a display with high current consumption such as a light emitting LED has many problems in the battery-powered wireless remote controller 22, and the indoor unit 21
It was a method of sending only without having a means to take in the information of. And, the power source of the wireless remote controller 22 is generally battery-powered, which makes it uncertain that a signal will arrive due to its life.
There was a problem that battery replacement work would occur.

The present invention solves the above-mentioned problems. An air conditioner capable of flexibly responding to a used form and ensuring signal transmission by making a wireless remote control usable in a simple wired form. A first object is to provide a remote control device.

A second object is to simplify the work of simple wiring and eliminate unnecessary cable processing.

A third object is to reduce the cost by using a clock display equipped with a wireless remote controller as the failure diagnosis display, expand the degree of freedom in design, and make the failure content display easy for the user to understand. .

A fourth object is to realize a driving monitor display on the wireless remote controller side for easy viewing.

A fifth object is to eliminate the battery replacement work of the wireless remote controller.

[0019]

In order to achieve the above first object, a remote display device for an air conditioner according to the present invention has a first means for receiving an infrared transmission signal of a wireless remote controller and a wireless remote controller transceiver. An indoor unit of an air conditioner provided with a connection connector for use with a wireless remote controller provided with an infrared transmitter and a connection connector for transmitting / receiving an indoor unit. The wireless remote controller transmitting / receiving connection connector and the indoor unit transmitting / receiving connection connector are provided.
