Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for commercializing equipment having a simple and easy-to-understand, highly serviceable means for confirming and displaying abnormal contents due to a failure of an air conditioner.

As a method of displaying the abnormality content of the indoor unit and the outdoor unit of the conventional air conditioner, the display method shown in FIG. 3 is generally used. Hereinafter, the display method will be described with reference to FIG.

As shown in the figure, the indoor unit body 101 and the outdoor unit body 102 are connected by a refrigerant pipe 103, and
The indoor unit side control device 104 and the outdoor unit side control device 105 are connected by an indoor / outdoor connection line 106. The indoor unit main body 101 is provided with a display means 107 connected to the indoor unit side control device 104. Further, an abnormality display means 108 is provided in the outdoor unit side control device 105.

In the above structure, the display means 107 normally displays information on the operation of the indoor unit main body 101, timer reservation, etc. However, when an abnormality occurs on the indoor unit main body 101 side, the indoor unit side control device 104 causes A signal corresponding to the content of the abnormality is transmitted to the display means 107, and the display means 107 performs blinking according to the signal and a display pattern different from the display during normal operation to notify that an abnormality has occurred. Further, when an abnormality occurs on the outdoor unit main body 102 side, the abnormality display means 108 provided in the outdoor unit side control device 105.
The details of the abnormality were displayed on the display to inform that the abnormality occurred.

Further, as disclosed in Japanese Unexamined Patent Publication No. 4-324046, there is also a structure provided with a wireless remote controller for operating a device and a wireless remote controller for displaying an abnormality content of the device.

[0007]

In such a conventional air conditioner abnormality display device, the abnormality display on the indoor unit main body 101 side is displayed during normal operation by using the display means 107 used during normal operation. Since it is a method that displays differently from the pattern, when checking the blinking pattern corresponding to the content of the abnormality, it is difficult to judge due to the influence of ambient light, etc. The abnormality content that must be confirmed and that has occurred on the outdoor unit main body 102 side is displayed on the abnormality display means 108. When confirming this abnormality content, the abnormality display means 108 inside the outdoor unit side control device 105 As can be seen, there was a problem that the cover of the outdoor unit main body 102 had to be removed.

The present invention is to solve the above-mentioned problems, and the abnormality contents of the indoor unit and the outdoor unit can be easily confirmed without being affected by the surroundings without removing the device cover, and the abnormality which is not necessary during normal operation. A first object of the present invention is to provide an abnormality display device for an air conditioner that can eliminate the display means.

A second object is to easily display the details of the abnormality.

[0010]

The abnormality display device for an air conditioner according to the present invention has a first object in order to achieve the first object.
The means is connected to the main body of the indoor unit and the outdoor unit of the air conditioner controlled by the wireless remote controller, the abnormality content transmission means provided in the main body, and the abnormality content transmission means, which enables external connection. Main unit side connection section provided in each main body, abnormality content receiving means, wireless remote controller provided with a display section for displaying the abnormality content by operating the abnormality content display switch, and remote control side connection connected to the abnormality content receiving means And a connection line connecting the main body side connection section and the remote control side connection section, and the connection line is connected and displayed when an abnormality content is confirmed.

In order to achieve the second object, the second means is to provide an abnormality content display switching section connected to the remote control side connection section of the wireless remote controller, and to connect the connection line to the remote control side connection section. In addition, the abnormality content display switching unit is activated to display the abnormality content on the display unit.

[0012]

With the configuration of the first means described above, the present invention connects the main body side connection portion of the indoor unit or the outdoor unit in which an abnormality has occurred and the remote control side connection portion of the wireless remote controller with a connection line to display an abnormality content display switch. By operating, the abnormality content of the indoor unit or the outdoor unit is transmitted from the abnormality content transmitting means to the abnormality content receiving means of the wireless remote controller through the connection line, and the abnormality content or the abnormality content is displayed. The corresponding code is usually
It will be displayed on the display of the wireless remote controller used to control the operation of the device.

Further, with the configuration of the second means, the display of the display unit is automatically switched to the abnormality content display by connecting the connecting line.
