DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner installed in a room to be air-conditioned, particularly at a high place.

[0002]

2. Description of the Related Art In recent years, air conditioners have been installed at a high place from floor installation to wall installation, ceiling installation, and ceiling installation, and the floor surface has been effectively utilized.
Repair work, etc. is also performed at high places, and easiness and safety of work are required.

[0003] A conventional air conditioner is disclosed in Japanese Utility Model Laid-Open No. 2-1166.
No. 25 is disclosed.

FIG. 6 is a perspective view of a main part of a conventional air conditioner. In FIG. 6, reference numeral 1 denotes an air conditioner main body, which has a side plate 2. An inspection window 3 is provided at a predetermined position on the side plate 2.

[0005]

However, the above-mentioned conventional structure is particularly difficult in the case of an air conditioner installed at a high place, especially when the inspection window 3 is installed.
Opening work is a high-altitude work, and it is necessary to remove locking tools such as screws. In addition, in order to inspect the piping sensor and check for dirt, it is necessary to raise the line of sight to the position of the inspection window 3.
In addition, since the size of the inspection window 3 is small enough to be accessible, it is difficult to visually perform the replacement work after the check, so that the check is practically performed only.

[0006] The present invention solves the conventional problems.
It is an object of the present invention to provide a high-altitude air conditioner that allows the inside of the air conditioner to be viewed from below while the air conditioner is installed.

[0007] Another object of the present invention is to provide an air conditioner that can be viewed from below without extending into the ceiling when it is installed above the ceiling while the visible range is widened.

Another object of the present invention is to provide an air conditioner that allows the inside of the air conditioner to be viewed even in a dark place such as behind a ceiling.

[0009]

In order to achieve the above object, the present invention provides an inspection port which allows the inside of the air conditioner to be visible at a predetermined portion, an opening / closing plate which covers the inspection port at normal times,
A hinge is provided to allow the opening / closing plate to rotate freely around one piece of the opening / closing plate.

[0010] Thus, the inside of the air conditioner can be viewed with the air conditioner installed, and it is easy to find an abnormality or a failure.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is to provide an inspection port at a predetermined portion of the outer periphery of an air conditioner so that the inside of the air conditioner can be viewed, and to cover the inspection port at normal times. An opening / closing plate, and a hinge for allowing the opening / closing plate to rotate about one piece of the opening / closing plate as an axis, and opening the opening / closing plate around the hinge at the time of inspection work or the like to open the inside of the air conditioner from the inspection port. It has the effect of making it easy to find abnormalities and failures by visual inspection.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, an opening / closing plate mirror provided inside the air conditioner of the opening / closing plate to reflect the inside of the air conditioner; An endoscope that holds an angle and operates in conjunction with the open / close plate is provided, and by opening the open / close plate even from below, an image of the endoscope reflected on the open / close plate is confirmed. As a result, it is possible to easily find an abnormality or a failure.

According to a third aspect of the present invention, in the first and second aspects of the present invention, a light that turns on and off in conjunction with opening and closing of the open / close plate is provided near the endoscope. Also, even in a dark place inside the ceiling, the lighting of the light by opening the opening / closing plate makes the inside of the air conditioner bright, thereby facilitating finding abnormalities and failures.
