BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to maintenance of a floor-embedded air conditioner, and more particularly to an air conditioner suitable for reducing the maintenance space of a filter.

[0002]

2. Description of the Related Art In a conventional air conditioner, since the dust amount standard defined in the Building Management Law is satisfied, the structure shown in FIG.
~ As shown in Fig. 10, a medium performance filter or a high performance filter (NBS standard 65) capable of filtering fine dust.
% Or 90%) 1B is installed in the chamber 1, and a door 20 for maintenance of the filter 1B is provided at the opening of the chamber 1 accommodating the filter 1B. This medium-performance or high-performance filter 1B needs to be replaced in a normal building after operating for 2500 hours to 3000 hours. Further, on the windward side of this filter 1B, a pre-filter 1A for removing large dust is provided.
Maintenance is required during operation for 1000 hours to 1500 hours (500 hours depending on the structure of the prefilter). Therefore, a maintenance door 20 for the filters 1A and 1B is provided, and since this door 20 is an open door, a maintenance space (a space where the door opens) S is required as a space for opening the door, as shown in the figure. there were. For example, the 10RT type shown in FIG. 9 has a length of 950 mm. Actually, it would be good if there is a maintenance space in front of the range occupied by the filter, but if there are optional items etc., those maintenance spaces are also required,
With hinged doors, maintenance of filters and optional items cannot be done unless the door is opened 90 °. Furthermore, if a part of the building projects in front of the door or if an object is placed, the door cannot be opened, and this defect is often found in the actual site after use.

[0003]

In the conventional air conditioner, a wide maintenance space for opening and closing the door of the opening is required to maintain the filter in the chamber, and the building must be constructed on-site after use. There was a problem that the doors could not be opened and closed due to the detection of protruding objects.

An object of the present invention is to provide an air conditioner which can improve workability without requiring a large maintenance space for maintaining a filter.

[0005]

To achieve the above object, an air conditioner according to the present invention comprises a chamber for accommodating a filter and a door which is opened and closed when the filter is maintained from the opening of the chamber. In the air conditioner provided, a plurality of rails are laid at the upper and lower ends of the opening and loosely insert the upper and lower ends of the door.

[0006]

According to the present invention, by inserting the upper and lower ends of the door into the rails laid on the upper and lower ends of the opening of the chamber, the door slides in the rail substantially parallel to the opening, Is opened. After maintaining the filter housed inside from the opening, slide the door along the rail to close the opening, the door is housed in the concave flange and attracted to the magnet, and the door's The elastic material attached to the inside is compressed by the seal rail provided on the inner circumference of the flange, and the airtightness of the chamber is maintained. When the air conditioner starts to operate, the chamber is in a negative pressure state, so a force in the same direction as the magnet attraction direction acts on the door due to the pressure difference from the outside atmospheric pressure, and airtightness is strengthened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

As shown in FIGS. 1 and 2, a chamber 2 accommodating a pre-filter 1 A and a medium-performance or high-performance filter 1 B and an opening 3 provided in the chamber 2 are opened and closed when the filter 1 is maintained. In an air conditioner provided with a door 4, two rails 5 and 6 laid at the upper and lower ends of the opening 3 for loosely inserting the upper and lower ends of the door 4 and one end of the rails 5 and 6 are closed. The stoppers 7 and 8 that are detachably mounted, and the other ends of the rails 5 and 6 that close the opening 3 are provided at 30 ° to 45 degrees toward the opening 3.
Swash plates 9 and 10 which are narrowed at an angle of ° to guide the door 4, and a concave flange 12 which is provided around the opening 3 to form a seal rail 11 on the inner periphery and which accommodates the closed door 4. ,
The seal rail 1 of the door 4 is provided with one or more magnets 13 attached to the flange 12 and attracting the closed door 4.
The elastic material 14 such as a cushion material is attached to the area in which the elastic material 14 is engaged with the elastic material 14. The door 4 has a handle 15 on the outer surface and rollers (not shown) on the upper and lower end surfaces, respectively.
By providing and, it becomes easier to open and close the door 4. The swash plates 9 and 10 may be integrally or separately formed with the rails and may be configured to have a surface for easily guiding the door 4.

The operation of this embodiment will be described with reference to FIGS. When the door 4 shown in FIGS. 3 and 4 is fully closed, the door 4 is rotated in the direction of arrow A shown in FIG. 3, the door 4 is detached from the magnet 13, placed on the rail 5, and moved in the direction of arrow B. To do. The opening 3 is gradually opened, and the door 4 is shown in a half-opened state in FIG. Further, by moving the door 4 in the direction of arrow B, the opening 3 shown in FIG. 6 is fully opened. Since the pre-filter 1A and the medium-performance or high-performance filter 1B show the whole, cleaning or replacement can be easily performed. Therefore, the thickness of the door 4 should be 15
~ 20mm, maintenance space is 30mm
The degree will be good.

Another embodiment of the present invention will be described with reference to FIG. The difference from the embodiment shown in FIG. 1 is that both ends of the rails 5 and 6 are closed beforehand and stoppers are not used. The door 4 can be attached and detached at any position in the same manner as the bran or shoji.

According to the present invention, the maintenance space of the filter maintained from the opening of the chamber is 30 mm.
The degree can be set to a certain level, and since it is not affected by the protrusions of buildings, the installation location of the air conditioner and the degree of freedom in design can be expanded. Furthermore, when opening and checking a hinged door with one end of the conventional door as the axis, if the strength of the member corresponding to the shaft side pillar is insufficient, or if it deforms due to transportation or construction, the door Not only will it hinder opening and closing, but the door seal structure will be destroyed, and air that has not been processed by the filter may enter, resulting in the failure of the filtering function, which is one of the functions of the air conditioner. It is completely improved by the present invention.

[0012]

According to the present invention, since the rail is laid in the opening of the chamber and the door is loosely inserted, the maintenance space for the maintenance of the filter is reduced and the door is prevented from being damaged and installed. It is possible to provide an air conditioner with an increased degree of freedom in location.
