DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having a built-in illumination lamp.

[0002]

2. Description of the Related Art In recent years, an air conditioner is controlled by an electronic control unit, and in addition to controlling a single device, a plurality of air conditioners are connected and managed by a communication technology and managed and operated as a system.

When a plurality of devices are managed and operated, an operation of assigning an address to each device occurs at the stage of installation of the device. In addition, an indoor unit is often installed with a body inside the ceiling, and therefore, an electrical box containing electrical equipment inside the body is installed behind the ceiling.

A conventional air conditioner having a built-in lighting device is disclosed in Japanese Utility Model Publication No. 2-70125.

Hereinafter, the conventional air conditioner will be described with reference to the drawings.

FIG. 3 is a longitudinal sectional view of a conventional air conditioner. In FIG. 3, reference numeral 1 denotes a housing of an indoor unit of the separation type air conditioner, which is attached to a wall surface in the room.
The housing 1 includes a body 2 and a front panel 3 attached to the front of the body 2. Reference numeral 4 denotes a blower housed in the body 2, reference numeral 5 denotes an indoor heat exchanger, and reference numeral 6 denotes a drain pan arranged below the heat exchanger.

[0007] Reference numerals 7 and 8 denote front and upper suction ports, and 9 denotes an air filter arranged between the suction ports 7 and 8 and the heat exchanger 5, which is put in and out through an opening 10. 11 is a vertical blade, 1
Reference numeral 2 denotes horizontal blades. By moving these blades, the direction of the wind blown out from the discharge port 13 can be adjusted.

Reference numerals 14 and 15 denote horizontally long recesses provided in the front panel 3, which are located above and below the front suction port 7, respectively. 16 is an illumination lamp housed in the recesses 14 and 15,
Its length is substantially equal to the width of the indoor unit. Reference numeral 17 denotes a reflection plate housed in the upper recess 14, and an illumination lamp 16 is attached thereto.

The reflecting plate 17 is pivoted about the fulcrum 18.
Swings to change the position of the illumination lamp 16 and the position of the reflection surface 19. That is, when the reflection plate 17 is turned downward, the illumination lamp 16 and the reflection plate 17 are brought into a state shown by a dashed line, and the inside of the housing 1, that is, the air filter 9 is illuminated by the upper reflection surface 19 (see a dashed line arrow).

On the other hand, when the reflecting plate 17 is turned upward,
The light of the illumination lamp 16 illuminates the front. Note that the above-mentioned reflection plate 17 is not provided in the lower recess 15.

Reference numeral 20 denotes lids for the recesses 14 and 15, which are packed in grooves 21 above and below the recesses. Reference numeral 22 denotes a handle provided on the lid 20, and reference numeral 23 denotes a shoji paper stuck on the front surface of the lid. The shoji paper 23 is stuck to the lid 20 in this manner so that this portion looks like a "lantern". I have to.

The operation of the air conditioner configured as described above will be described below.

First, when the indoor unit is operated, the illuminating lamp 16 is turned on.
When is turned on, the upper and lower portions of the indoor unit are illuminated by a lantern wind, and this indoor unit can be used as Japanese-style mood lighting.

When the reflecting plate 17 is turned downward, the light of the illumination lamp 16 illuminates the inside of the housing 1. Then, the degree of contamination of the air filter 9 is checked through the suction port 7. If the air filter 9 is unnecessarily dirty, the air filter 9 is pulled out from the opening 10 and the air filter 9 is removed.
Perform cleaning.

On the other hand, when performing a service check of the blower 4 and the heat exchanger 5 in the body 2, the front panel 3 is removed from the body 2, and the illuminating lamp 16 is taken out together with the front panel 3 and the body 2 is removed. The front surface of the air conditioner is opened so that the service inspection of the blower 4 and the heat exchanger 5 can be performed.

[0016]

However, the above-mentioned conventional construction is not applicable when the body 2 of the indoor unit is installed in the ceiling and the electrical box containing the electrical equipment in the body 2 is installed behind the ceiling. Since the builder must own the illuminating lamp and set the address and other settings, there is a drawback that installation and construction are difficult and there is a risk of erroneous setting.

An object of the present invention is to solve the conventional problem, and an object of the present invention is to provide an air conditioner in which an installer can surely set and confirm an address and other settings even in darkness.

[0018]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides a cover for opening and closing an electric box of an air conditioner, a lighting device for illuminating the inside of the electric box, and a lighting device with a timer which operates in conjunction with opening and closing of the cover. It consists of a switch and

Thus, even in the dark, the installer can surely set and confirm the address and other settings. Further, it is possible to prevent the lighting device from being turned on and off unnecessarily.

[0020] Further, a timer reset switch for resetting the timer is provided.

Thus, even after the lighting device is turned off by the operation of the timer, the lighting device can be easily turned on again.

[0022]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to a lid for opening and closing an electrical box of an air conditioner, a lighting device for illuminating the inside of the electrical box, and a timer-equipped lighting which is linked with opening and closing of the lid. The lighting device is turned on by opening the electrical box, and has the effect that the installer can surely set and confirm the address and other settings even in the dark.

Further, even if the installer has left the electrical box cover open during construction and inspection, the lighting device is turned off after a predetermined time, so that unnecessary lighting can be prevented. After the construction and inspection are completed, the lighting device is turned off by closing the lid of the electrical box, so that it is possible to prevent forgetting to turn off the light.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, a timer reset switch is further provided. Even when the lighting device is left open and the lighting device is turned off, the timer is reset by operating the timer reset switch when necessary, and the lighting device can be easily turned on again.
