Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem on an air conditioner wherein the operation of a refrigerating cycle can be executed so far as the performance of the refrigerating cycle for cooling and heating is not impaired, and abnormality display is always presented on a display device regardless of contents of abnormality of devices, that the display device is too bright in the dark, for example, before sleeping , which disturbs daily life. <P>SOLUTION: Lighting and extinction of abnormality display of the display portion of the device can be selected by an operating means such as a remote controller, and when the extinction is selected, the abnormality display is temporarily presented only when the operation for starting and stopping the air conditioner or displaying abnormality is performed. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a display device that displays an operating state of an air conditioner to the outside.

This type of conventional display device will be described with reference to FIG. 2, for example. If an abnormality occurs in the air conditioner, one of the protection devices 30a and 30b is activated, and a protection device operation signal is sent to the input circuit 16 of the microcomputer 43. When input, a deactivation signal is output to the driving relay 20, the contact 20a is opened, the contactor 33 is deenergized, and the operation of the compressor 32 is stopped. At this time, a lighting signal for the display 22a or 22b is output from the output circuit 37 of the microcomputer 43 via the buffer 34. When the abnormality is removed, self-holding is released and the system can be restarted. However, since the lighting of the indicators 22a and 22b is continued by the display signal output means 31, it is easy to find the cause of the abnormality. Can do. As described above, there is a display indicating an abnormality (see Patent Document 1).
Japanese Patent Laid-Open No. 62-123247

  However, in the above-described conventional configuration, the abnormality is continuously displayed to the outside in any abnormality, but the cooling operation, heating operation, heating operation in the cooling operation, heating operation, dehumidifying operation (hereinafter referred to as basic performance) is not lost. When driving and dehumidifying operation (hereinafter referred to as basic operation) are possible, there is a problem that the user is visually concerned when the surroundings are dark, such as before going to bed. In order to solve the above problems, in the present invention, it is possible to hide the display of an abnormality that does not lose the basic performance except when necessary.

  The present invention solves the above-described conventional problems, and provides a display device that hides an abnormal display that does not lose basic performance except when an abnormality occurs, when an abnormal display is requested, or when a device is operated such as starting or stopping operation. It is for the purpose of provision.

  As is apparent from the above description, the present invention can realize a display device that does not interfere with daily life by eliminating an abnormal display that does not lose basic performance.

According to a first aspect of the present invention, there is provided a display device capable of notifying a user of an abnormality without hindering daily life by erasing the abnormality display except in a case other than a certain condition at the time of abnormality without losing the basic function. Can be realized.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 is a block diagram of an air conditioner according to Embodiment 1 of the present invention. In FIG. 1, a remote controller 1 for remotely controlling the operation / stop / function of the air conditioner, an operation switch 2 mounted on the main body of the air conditioner and capable of controlling the start / stop of operation, the remote controller 1 or the electricity of the operation switch 2 The control part 3 which receives a signal and controls an air conditioner and the display apparatus 4 which displays operation / stop and an air cleaner operation / stop and abnormality by LED by the control part 3 are shown.

  In the display device of the air conditioner of FIG. 1, when an abnormality that does not impair the basic performance of the device is performed on the display device 4 for a certain period of time, the abnormality display is then turned off. Thereafter, when the operation signal from the remote controller 1, the mode change operation, the abnormality display request signal, the operation signal from the operation switch 2, or the mode switching signal is input, the operation mode of the device is displayed on the display device 4 for a certain period of time. The fixed time is a time sufficient for the operator to confirm the display and is several seconds to several minutes. Further, it is assumed that whether or not to perform this control can be selected by operating the remote controller 1 or the operation switch 2.

  The display device of the present invention has basic performance and attached functions, can be operated if there is no problem in basic performance, and is also used as a display device of a device having a display device that does not require constant brightness. Applicable.
