Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-embedded air conditioner, and more particularly to the structure of a filter device for the air conditioner.

[0002]

2. Description of the Related Art As an air conditioner, there is a ceiling-embedded type, for example, as shown in FIG. This type of air conditioner has an air suction port 2 on one side of its main body 1 and a blowout port 3 for sending out heat-exchanged air on the other side thereof. The chambers are connected by a suction duct 4 and a blowing duct 5. Inside the main body 1 near the suction port 2, a heat exchanger 6
And a dew tray (not shown) for receiving and discharging defrosted water from the heat exchanger 6, and a blower 7 having a blower opening corresponding to the blowout opening 3 is provided inside the blowout opening 3. A filter device 8A is provided in front of the suction port 2. The filter device 8A is composed of, for example, a zigzag mountain-shaped filter 11A as shown in FIG. 4 and a synthetic resin frame 9A for housing the filter 11A.

[0003]

By the way, there is a problem that the larger the frame 9A made of synthetic resin, the more easily it is deformed and it becomes difficult to mount it at a predetermined position.
Therefore, it is an object of the present invention to provide a filter device for an air conditioner, which is small in size even if it is large and can be easily attached to a predetermined position.

[0004]

The present invention has been made to solve the above-mentioned problems, and heat exchange is performed on the suction port side in a main body having a suction port on one side and an air outlet on the other side. A blower having a blower port corresponding to the blower outlet is provided on the blower outlet side, while a filter device is provided in front of the suction inlet, and a suction duct and a suction duct are provided between the suction inlet and the blower outlet and the air-conditioned room. In an air conditioner that is connected to a blowout duct and installed in the ceiling, the filter device is a pair of frames formed in a U-shaped cross section and facing each other, and a metallic net disposed between the frames, A filter formed in a zigzag mountain shape and placed on the net, two sets of an inner plate and an outer plate that sandwich the both side surfaces of the filter and are provided between the side end portions of the opposite frames, and these both sides. The filter using a plate Constituted by a plurality of screws for clamping fixation. The frame is made of steel plate.

Further, the width of the upper surface of the frame having a U-shaped cross section is smaller than that of the bottom surface. Further, the inner plate is formed in an L shape, and a plurality of screw holes are provided on the front surface. In addition, the outer plate is formed in an inverted L shape, and a plurality of holes for inserting screws are formed on the front surface so as to face the holes of the inner plate. Further, the filter device is provided on the inlet side of the suction duct.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIG.
~ It demonstrates based on FIG. In the figure, reference numeral 1 denotes a main body of an air conditioner installed on the ceiling, which has an air inlet 2 on one side and two outlets 3 on the other side. A suction duct 4 and a blowout duct 5 are connected between the air outlet 3 and an unconditioned room (not shown). A heat exchanger 6 is provided near the suction port 2 inside the main body 1, and a dew tray (not shown) that receives and discharges defrosting water dripping from the heat exchanger 6 is provided below the heat exchanger 6. A blower 7 having fan cases 7a and 7b respectively corresponding to the two outlets 3 and having two fans driven by a single fan motor 7c is provided inside, and a suction port 2 is provided. A filter device 8 is provided in front of. The arrow in FIG. 1 indicates the direction of air flow.

By the way, the feature of the present embodiment lies in the structure of the filter device 8, and as shown in FIG. 2, a pair of frames 9 having a U-shaped cross section and facing each other, and the frame 9-9. The metal net 10 arranged between them, the filter 11 formed in a zigzag mountain shape and placed on the net 10, and both side surfaces 11a of the filter 11 are sandwiched,
Two sets of inner plates 12 and outer plates 13 provided between the side ends of the opposing frames 9-9, and a plurality of screws 14 for sandwiching and fixing the both side faces 11a of the filter 11 using these both side plates 12 and 13 are used. That is what I configured.

The frame 9 is made of steel plate in order to reduce deformation, and the width w of the upper surface of the U-shaped frame 9 is made smaller than the width W of the bottom surface to the minimum necessary to reduce the weight. In addition, the net 10 and the filter 11 can be easily placed between the opposing frames 9-9. Further, the inner plate 12 is formed in an L shape in consideration of ease of use and stability after assembling, and a plurality of screw holes 12a are provided on the front surface. Also the outer plate
Similarly to the inner plate 12, the 13 is also formed in an inverted L shape to improve usability and stability after assembly, and the inner plate 12 has a hole on the front surface.
A plurality of holes 13a for inserting screws are provided opposite to 12a. Since both sides 11a of the filter 11 sandwiched between the inner plate 12 and the outer plate 13 can be easily pierced by the screw 14, it is not necessary to provide a hole. FIG. 3 shows a filter device 8 assembled using the components described above. In addition, the filter device 8 is connected to the inlet side 4 of the suction duct 4.
The configuration provided in a may be adopted.

[0009]

EFFECTS OF THE INVENTION In the case of the filter device composed of the components as described above, the frame is less likely to be deformed as compared with the conventional product using the frame made of synthetic resin, so that a larger air conditioner is provided. Since it has a simple structure, it is easy to assemble, attach, and replace the filter.
