2. Description of the Related Art In recent years, air conditioners having an air purifying function have become mainstream.

The configuration of this type of conventional air conditioner will be described with reference to FIG. As shown in the figure, a mixing box 101 for mixing return air and outside air introduced into the machine, a main filter 102 and a pre-filter 103 located on the lee side of the mixing box 101 for cleaning air A, and the main filter Bolt 104 and nut for fixing 102 and pre-filter 103
105, a filter box 108 having a stopper 106 and an inspection door 107, and a fan coil box 109 having a function of heating or cooling air A located on the leeward side of the filter box 108 and sending the air to the room. Had a configuration.

With the above configuration, the main filter 102 and the pre-filter 103
By tightening the nut 105 via the stopper 106,
It is fixed by pressing it toward the fan coil block 109. Then, when performing maintenance, a person enters the machine, loosens the nut 105 and the stopper 106, pulls out the main filter 102 and the pre-filter 103 toward the mixing box 101, and removes the main filter 102 and the pre-filter 103 from the inspection door 107 arranged horizontally. Was.

Problems to be Solved by the Invention In such a configuration of the conventional air conditioner, when maintenance is performed, a person enters the machine, loosens each nut 105 and the fastener 106, and performs a main filter 102 and a pre-filter 103.
It is necessary to pull out the inspection door 107 and take it out of the inspection door 107, which is troublesome, requires a large storage space, and increases the size of the filter box 108.

The present invention solves the above-mentioned problems, and has an object to provide an air conditioner that is easy to maintain and has a small space.

Means for Solving the Problems In order to achieve the above object, the present invention provides a filter box provided with an inspection door on the side, a pre-filter provided so as to be able to be drawn out, and one end rotatably supported in the filter box. And a filter storage frame for supporting the main filter in the filter box with a detachable fixing bracket at the other end,
The main filter and the pre-filter can be taken out from an inspection door provided in the filter box.

According to the present invention, when performing maintenance, the prefilter opens the inspection door and slides out directly to take out the main filter, and the main filter removes the fixing bracket, rotates the prefilter storage frame to the windward side, and pulls out the main filter when performing maintenance. Things.

Embodiment One embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

As shown in the figure, a mixing box 1 for mixing return air and outside air introduced into the machine, and a filter box 4 in which a main filter 2 for cleaning air A and a pre-filter 3 disposed downstream of the mixing box 1 are provided. A fan coil box 5 having a function of heating or cooling the air A and sending the air into the room on the weathering side of the filter box 4, and the pre-filter 3 is slid between slide rails 6 and stored therein. 7, one end of the pre-filter storage frame 7 is supported by a rotatable supporting bracket 8, and the other end is provided with a fixing bracket 9 for tightening and supporting. The main filter 2 is pressed and fixed in the direction of the fan coil box 5 by the pre-filter housing frame 7 which is in contact with the outer periphery of the rear surface, and an inspection door 10 is provided in the side filter box 4 of the fixing bracket 9. .

With the above configuration, in the case of maintenance, when performing maintenance of the main filter 2, the inspection door 10 is opened, the fixing bracket 9 is removed, and the pre-filter storage frame 7 is moved windward with the support bracket 8 as a fulcrum as shown by oblique lines in the drawing. , And pull it out of the filter box 4 directly for maintenance.
In addition, the pre-filter 3 that requires frequent maintenance is an inspection door.
It can be done directly just by opening 10.

Effects of the Invention As is clear from the description of the above embodiment, according to the present invention, since the main filter and the pre-filter can be easily removed directly from the outside, it is possible to perform the work performed by a person inside the machine as compared with the related art. There is no need for a space for moving the main filter inside the machine, and it is possible to provide an air conditioner in which the maintenance is easy and quick, and the storage space can be reduced, so that the filter box can be made compact.
