Description

[Detailed description of the invention] This invention relates to an improved configuration of an air conditioner such as a ceiling-embedded type air conditioner, and in particular, parts such as a dew pan are removed to facilitate maintenance, inspection, and cleaning.

As shown in Fig. 1, a conventional air conditioner such as a ceiling-embedded type air conditioner includes a main body 2 installed in a so-called ceiling space above a ceiling plate 1, and a suction port attached to the bottom of the main body 2 in the center. 3 and a decorative panel 5 equipped with air outlets 4, 4 on both sides of the opening, and a top blowing type centrifugal air blower 6 is installed in a suction chamber 8 in a cylindrical interior body 7 constituting the main body 2. A blowing chamber 1 is provided with a pair of heat exchangers 9, 9 formed between an exterior body 10 in the form of a container with an opening at the bottom of the main body 2 and the interior body 7.
1, the suction chamber 8 is the suction port 3, and the discharge ports 12A, 12A are formed on the lower surfaces of both sides of the blow-off chamber 11 of the blow-off passages 12, 12 from the heat exchangers 9, 9.
and the air outlet ports 4, 4, respectively.

In such a structure, the dew pans 13, 13 that receive the dew water dripping from the heat exchangers 9, 9 are arranged above the large diameter part of the blower 6, but the blower 6 and the inner body The distances L and M from 7 are the dew pan 1
The width dimension of dew pans 13 and 13 is smaller than that of dew pans 13 and 13.
cannot be removed for cleaning, and therefore the dew pans 13 and 13 must be removed from which the partition plate 14 supporting the blower 6 has been removed, resulting in poor work efficiency and the need for frequent attachment and detachment of the blower 6. It has also become a habit to accelerate deterioration and damage.

This proposal was made in view of the above points, and the blower is biased to one side, and the dew pan is installed side by side on the other side, and the distance between the blower and the partition plate is adjusted to the width of the dew pan. The dew pan is made larger in size so that the dew pan can be attached and removed without regard to the blower, and the dew pan can be easily removed for cleaning.

An embodiment of the present invention will be described below with reference to FIG.

Reference numeral 21 denotes an exterior body 22 formed in the shape of a hollow container with an opening on the bottom surface, and a decorative panel 2 that is attached to the opening on the bottom surface of this exterior body 22 and also covers the opening 24 of the ceiling board 23.
The exterior body 22 is installed in the ceiling space above the ceiling board 23, and is attached to the ceiling beam (not shown) using bolts 26, 26, etc. It is suspended and supported from any member such as This exterior body 22 has partition plates 29 and 30 disposed therein with a space between them and both side walls 27 and 28, respectively, and a suction passage 32 in which a blower device 31 is disposed between the partition plates 29 and 30. Blowout passages 33 and 34 are formed between the partition plates 29 and 30 and the side walls 27 and 28, respectively, and are opened on substantially the same plane as the suction passage 32, and near the discharge port of the blower device 31, The space between the partition plates 29 and 30 is divided into upper and lower sections, and the suction passage 32 is located at the lower part and the heat exchange chamber 3 is located at the upper part.
A partition plate 36 and an auxiliary plate 37 forming a partition plate 5 and a partition plate 36 are disposed.

The heat exchange chamber 35 includes a refrigerant compressor (not shown).
A heat exchanger 38 such as a so-called fin-and-tube type heat exchanger 38, which forms a refrigerant cycle together with the air blower 3
The dew pan 39 is disposed below the lower end of the heat exchanger 38, and is inclined at a large angle α of 40 degrees or more with respect to the perpendicular, so that it is higher on the discharge side of the heat exchanger 1 and lower on the side of the partition plate 29. The dew water from the heat exchanger 38 is received and stored. The other partition plate 30 forms one wall of the air passage 40, has an upper end that covers an area above the outlet of the air blower 31 with a gap therebetween, and is extended and bent so as to reach the high edge of the heat exchanger 38. A windside 41 is formed. The air guide side 41 is formed with a slope that is low toward the partition plate 30 and high toward the heat exchanger 38 with respect to the outlet of the blower 31, and transforms the accelerated air upward from the blower 31 to the side. do.

The blower device 31 has its discharge port end attached to the partition plate 36, and is disposed close to the other partition plate 30 and biased to one side of the suction passage 32, and has a large diameter portion and one partition plate 29. A large distance A is formed between the two. The dew pan 39 is arranged biased toward one partition plate 29 so as to be located above between one partition plate 29 and the air blower 31, and its width dimension B
is smaller than the distance A between the partition plate 29 and the air blower 31 and smaller than the distance C between the partition plate 29 and the partition plate 36. The auxiliary plate 37 forms a step downward so as to be able to place and support the dew pan 39, and is disposed facing substantially above between one of the partition plates 29 and the air blower 31, and its width D is set to be the same as that of both the partition plates 29 and the blower 31. It is desirable that the spacing A between the holes 31 and 31 be approximately the same or slightly smaller.

42 is located on the leeward side of the heat exchanger 38,
A flow divider plate whose one end is attached to the ceiling wall 43 of the exterior body 22, and whose lower end is in contact with or close to the heat exchanger 38, directs the accelerated air from the air blower 31 passing through the heat exchanger 38 to the The flow is divided into blowout passages 33 and 34. Heat exchanger 38 at the other end of the lower part of this flow dividing plate 42
The contact position with or close to the opposite position is the heat exchanger 3
The heat exchanger 3 is arranged so that the air volume to the blow-off passage 33 near the side 8 is greater than the air volume to the blow-off passage 34 on the side further apart.
It is set to be offset from the center of the opposing surface of No. 8 toward the lower end side. This is because the flow velocity of the accelerated air passing through the heat exchanger 38 through the outlet passage 33 near the heat exchanger 38 is higher than that through the other outlet passage 34 which is further away, and if the accelerated air is located approximately in the center, the Panel 2
One of the five air outlets 44 and 45
Since the discharge will be substantially biased toward the
Care has been taken so that the wind speeds blown out from the air outlets 44 and 45 are approximately close to each other.

Reference numeral 46 denotes a guide plate disposed below the inner surface of the heat exchanger 38, one end of which is disposed above the dew pan 39, and the other end located at a hanging position of the high end edge of the heat exchanger 38. It is formed in a size that protrudes more toward the partition plate 30 side, and is lower on the dew pan 39 side in order to receive the dew water dripping from the heat exchanger 38 and guide it down to the dew pan 39, and on the discharge port side of the blower device 31. It is located at a slightly higher slope. An arbitrary heat-insulating covering 47 such as foamed polyethylene is attached to the inner circumferential surface of the exterior body 22 and both the inner and outer surfaces of the partition plates 29 and 30 as required. Reference numerals 48 and 49 refer to the opening periphery of the exterior body 22, the lower ends of the partition plates 29 and 30, and the decorative panel 25.
A sealing material made of an elastic body interposed therebetween prevents communication between the suction passage 32 and the blow-off passages 33 and 34, thereby preventing short circuit between the blow-off air and the suction air. Reference numeral 50 denotes a suction port that communicates with the suction passage 32 formed in the center of the decorative panel 25 and is provided with a filter 51 .

Since the present invention is configured as described above, when the dew pan is removed for cleaning etc., the work can be done from between one partition plate and the blower device without removing the blower device, making cleaning the dew pan easy. It is.
In addition, maintenance, inspection, and repair of the air blower can be easily done by disassembling the air blower together with the partition plate, regardless of the dew pan, since the air blower is installed in parallel with the dew pan. Furthermore, since the dew pan and the blower are arranged side by side, the height of the main body can be reduced, there are fewer restrictions on the selection of installation positions in the ceiling space, etc., and the design and manufacture can be simplified.
