[0004]

Since the shape of the main body described above is a polygonal cylinder, it is unavoidable that a gap (gap) is formed between the flange pieces. That is, even if the sealing material is attached to the flange piece and the main body and the panel are securely combined, there is a gap between the flange pieces. Therefore, it is conceivable that a part of the air flowing out of the main body leaks out of the main body through the clearance, and the flow rate decreases. Further, when the air is cooled, dew may occur on the outer wall of the main body.

According to the present invention, the polygonal main body provided with the flange piece and the panel are securely sealed to prevent air from leaking from the main body to prevent a decrease in flow rate and to prevent dew on the outer wall of the main body. The purpose is to prevent the occurrence of.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is an air conditioner called a four-direction ceiling cassette type air conditioner, which comprises a main body 2 and a decorative panel 3 (hereinafter simply referred to as "panel"). The main body 2 is arranged behind the ceiling and houses a heat exchanger and a blower (described later). The panel 3 is arranged below the main body 2 so as to be substantially flush with the ceiling. Reference numeral 4 denotes a suction grill (suction port), which is attached to the panel 3 substantially at the center thereof. Reference numerals 5a, 5b, 5c, and 5d are outlets for cold air cooled by the heat exchanger, and are provided around the suction grill 4. Then, the indoor air is sucked into the suction grill 4 by the operation of the blower or the like, then cooled by the heat exchanger in the main body 2 and discharged from the respective outlets 5a, 5b, 5c, 5d.

FIG. 2 is an exploded perspective view of the main body 2.
Has an octagonal prism shape composed of four short pieces 6 and four long pieces 7, and an opening 8 is formed in the lower part thereof. Reference numeral 9 denotes a blower (turbo fan) arranged in the center of the main body, 10 denotes a plate fin type cooler (heat exchanger) arranged around the blower, 11 denotes a refrigerant pipe connected to the cooler, 12 Is a drain pump, 13 is a drain hose connected to this pump, and 14 is a fixture attached to a short piece. Reference numeral 16 is a heat insulating plate material attached to the inner wall of the long piece 7, and 17 is a substantially U-shaped heat insulating tool arranged on the short piece.

Reference numeral 18 is a heat insulating member made of styrofoam arranged in the opening 8 of the main body 2 and also acts as a drain pan. Reference numeral 19 is a suction port provided at the center of this member, and 20 is a blowout port provided around this suction port, which is connected to the blowout ports 5a, 5b, 5c, 5d of the above-mentioned panel. Two
1 is a drain receiver. Two grooves 22 and 23 are formed by connecting adjacent short pieces of the heat insulating member.

Numerals 24 and 25 are fixtures for fixing the heat insulating member 18 to the opening 8 of the main body 2. These fixtures 2
4, 25 are provided with a fixing piece 26 extending upward, a locking piece 27 and an engaging piece 28 extending downward. Then, by fixing the end portions 29 of the fixtures 24 and 25 to the short flange pieces 30 of the short pieces 6 of the main body 2 as shown by the one-dot chain line arrows, the fixing pieces 26 of the fixtures 24 and 25 become the grooves of the heat insulating member 18. 22 and 23 are inserted. This determines the position of the heat insulating member 18.

Here, the feature of the present invention is that a combination of a plurality of (long / short) flange pieces 31 and 30 (see FIG. 2) provided on the edge of the opening 8 of the main body 2 and the panel 3 (see FIG. 1). In structure. 3 shows the main body 2 and the flange piece 31,
The relationship with the sealing materials 32 and 33 attached to 30 is shown.

An adhesive is applied to the back surfaces of the sealing materials 32 and 33, and the width dimension 2A of these sealing materials 32 and 33 is set to about twice the width dimension A of the flange pieces 30 and 31. Has been done. Therefore, after sticking one side 34 of the sealing materials 32 and 33 to the surface 35 of the flange pieces 30 and 31, the other side 36 of the sealing materials 32 and 33 is bent from the one-dot chain line portion to the back surface of the flange pieces 30 and 31. Attach it. By such an operation, the flange pieces 30 and 31 are surrounded by the sealing materials 32 and 33.

The length dimension C of the sealing material 33 attached to the long flange piece 35 is set longer than the length dimension B of the long flange piece 31, while the short flange piece 3 is used.
The length dimension D of the sealing material 32 attached to 0 is set shorter than the length dimension E of the short flange piece 30.
Here, the sealing material 33 is attached to the long flange piece 35.
At this time, since the sealing material 33 is longer than the long flange piece 31, the end portion (extension part) 37 of the sealing material 33 closes the gap 38 between the long flange piece 31 and the short flange piece 30 to close the short flange piece. Extends to 30. Next, the short flange piece 30
The sealing material 32 is attached to. By attaching the sealing material 32, the eight flange pieces 30 and 31 are continuously connected by the sealing materials 32 and 33. This state is shown in FIG.

As described above, since the flange pieces 30 and 31 are continuously connected by the sealing materials 32 and 33 and the panel is applied to the flange pieces 30 and 31, the flange pieces 30 and 31 are divided. However, the air does not leak from the gap 38. That is, as shown in FIG. 5, since the flange piece 31 and the panel 3 are brought into close contact with each other via the sealing materials 32 and 33, a part of the temperature-adjusted air is part of the main body 2 and the drain pan 18 as shown by the broken line arrow. Even if the air enters the gap 40 between the main body 2 and the main body 2, the air is unlikely to leak to the outside 2. This does not reduce the flow rate of the temperature-controlled air. Further, even when this air is cooled, it does not leak to the outside of the main body 2, so that it is possible to reduce the risk of dew formation on the outer wall 41 of the main body 2.

FIG. 6 shows another embodiment of the present invention.
The difference from the above-described embodiment is that the sealing materials 60, 61, 6
The lengths 2, 63 and 64 are not determined according to the lengths of the respective flanges 30 and 31, and the joint 65 between the sealing members is the central portion of the long flange piece 31. That is, the sealing materials 61, 62, 64 attached over the long flange piece 31 are divided into two, and the sealing material 61, 62 first closes the gap 38 between the flange pieces 30, 31, and then, The sealing materials 61, 62, 64 are attached along the flange piece 31, and the sealing materials 61, 62 are spliced together at the substantially central portion of the long flange piece 31.

[0017]

As described above, according to the present invention, an opening is provided at the bottom of a polygonal cylindrical main body, and flange pieces extending outward are formed at the edges of the opening, respectively. Since the gap between the flange pieces is closed by the sealing material attached over the flange pieces, there is little risk of air leaking out of the main body from this gap, and the decrease in air volume can be suppressed to a small extent.

Further, by preventing the leakage of the air in the main body, when the air is cooled, it is possible to prevent the dew on the outer wall of the main body. Furthermore, if the sealing material attached to one flange piece is extended to the other flange piece and the extended portion is attached to the other flange piece, the length dimension of the sealing material is the length of the flange piece. It is not always necessary to make the length of the seal material substantially coincide with the length, and this makes it possible to manage the length of the sealing material to some extent.
