Abstract

PURPOSE:To make a frame structure such as struts and others unnecessary, by giving strength to support a heat exchanger unit and a fan unit to a U-shaped board itself, by using a board of which section is nearly a U-shape as the main component material of an outer casing. CONSTITUTION:A completed air conditioner is composed of a solid board having strength, of which section is nearly a U-shaped, provided with four corners 59a-59d by fitting flange pieces 3a and 3b. In this case, the solid board can be used as a strengthened member enough to support units such as a heat exchanger unit 31 and a fan unit 32, when it is allocated to be installed on the floor in the upright state. Besides, the reinforcement to the right and the left directions is made by a drain pan 34 striding over the both right and left sides 21 and 22 of a board 1, and a crossed reinforcement is made by a slanted heat exchanger 33 striding over the drain pan 34 and the upper edge of the back side 23 of a board 1, and the fan casing 39 of a fan unit 32 striding over the drain pan 34 and the underside edge of the back part 23 of a board 1, respectively. The outer casing of an air conditioner of which strength is increased can be obtained by utilizing the above-mentioned units as reinforcement members.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention relates to a floor-standing packaged air conditioner.

(B) Prior Art Conventionally, in a floor-standing packaged air conditioner, after installing and fixing pillars each having a cross-section in the four corners of the bottom box, separate left and right side panels, top panels, and The front panels are each screwed together to form a casing, and equipment such as a heat exchanger and a blower are fixed to the strong pillars via angle frames.

(c) Problems with the conventional technology: It requires a bottom box and five panels as components of the casing, and in order to assemble these panels and install equipment such as a heat exchanger and blower, it requires four columns and straddling these columns. Because it used a frame structure consisting of multiple angle frames that were bent, there were a large number of parts (assembly was complicated and manufacturing costs were relatively high).

B) Object of the Invention The present invention provides an inexpensive and lightweight air conditioner that reduces the number of components of the casing, eliminates the need for frame parts such as transmission pillars, etc.

(e) Key Points of the Invention A casing consisting of a substantially U-shaped plate in cross section with one side open, and a plate member that closes openings at both upper and lower ends of the plate and the open surface, respectively; The structure consists of a heat exchange unit whose bottom part is fixed to the U-shaped plate, and a blower unit that comes into contact with the lower part of the unit and is fixed to the U-shaped plate, which increases the strength of the U-shaped plate itself. The heat exchange unit and the ventilation unit housed in the housing are reinforced by serving as strength members.

(f) Embodiment of the Invention An embodiment of the invention will be explained based on the drawings. In Fig. 1, (1) shows a pair of left and right mounting flange pieces (3a) (3b) on the open surface (2) side. A plate with a substantially U-shaped cross section and a single thin sheet metal with a wall thickness of 0.6 mm, height dimension] 87
It is used as the main component of the casing (4), which is bent into a slim shape with a width of 0 inch, a width of 540+++m, and a depth of 175m.

(5) are the screw holes (

16) and closes the open surface (2).

(17) (Openings at both upper and lower ends θQ of 1-machi Mako-shaped board (1)
The upper plate member (17) is a top flange piece (17) formed by bending the two ends of the left and right side parts (2OL27J) of the U-shaped plate (1) and the upper end of the back part (23). 24a

The screw hole (291 (30)) is fitted along the outer surface of the
It is designed to be installed.

(31) and (32) are a heat exchange unit and a ventilation unit having a width dimension that is approximately the same as the inner width dimension of the U-shaped plate (1),
The heat exchange unit (C3I) is a unit block with a drain pan (G) fixed in advance to the lower end of the heat exchanger (O), and an electric motor (A) with a suction fan (13 or 1) is attached to the supporting legs (37). and a unit block 17 that is fixed in position in a sheet metal fan casing (39) with an open back via a nozzle plate (38). ]) There is a screw hole (4:11 (4(
B) Fixtures to be fixed with (4 holes are holes for fixing the drain pan (34) across the recesses (46a x 46b) of the mounting flange pieces (3a) (3b), (4G) is the fan casing (3! A plurality of mounting pieces that are spot welded along the scroll part (47) of i and fixed with the screw holes (48) and welding holes on the back part (to)) (49).

Therefore, to assemble the air conditioner, first, as shown in Fig. 1, lay down the plate (1), which is a single plate bent into a substantially U-shaped cross section, with the back surface C23) facing down, and then open the open surface (2). After storing the air blower unit (G21), which has been made into a unit block in advance, from this open surface in a state in which it is slightly expanded to the left and right as shown by the dashed dotted line in Fig. 2, and the mounting piece (4G) is fixed to the welding pole (49). , unit block heat exchange unit) (31) on one open surface (2

Then, fix the U-shaped plate (1) with the left and right side parts (2I) (221) on the rear and back parts (from the outside with screws t53).

After that, after fixing the upper plate member 07) and the lower plate member 0119 with screws C)4), the electrical box a9 is stored in the housing (4) from the open surface (2), and the lower end is fixed to the lower plate. Connect the member (to the country) and fix the upper end to the fan casing (3■ with screws 65), and then fix the blower unit (reinforce and support the three. Then, fix the main plate 03, which is the front plate member (5)) with screws 66). And the sloped lower edge 6? ) to the lower plate member (mark 1) and attach the auxiliary plate (
The assembly is completed when I6) is tightened with screw 6. Note that if the 6) G mark on the screw exposed to the front is covered with a cosmetic sash (not shown), the aesthetic appearance will not be impaired.

The air conditioner completed in this way has a substantially U-shaped cross section (1) with a mounting flange piece (3a x 3b).
Since it is made of a strong single board with corners (59a), (59b)', (59c) and (59d), it is difficult to exchange heat when placed on the floor in an upright position. 3])
It can also be used as a member with sufficient strength to support devices such as air blower units (A), and can also be used as a substantially U-shaped single plate (A).
1) Both left and right side parts C7! The drain pan (34) that spans 11H is reinforced in the left and right direction, and the tilted heat exchanger (3■ and Drain pan (31 and back part (c)
The blower units (three fan casings (39)) that span the lower part are each reinforced with bracing, and these devices can also be used as reinforcing members to create a structure with increased strength.

(g) Effects of the invention Since the present invention uses a substantially U-shaped plate in cross section with one side open as the main component of the exterior casing, this U-shaped plate itself has the strength to support the heat exchange unit and the blower unit. In addition, the heat exchange unit, which is housed and fixed in the U-shaped plate in a braced state, and the ventilation unit, which is in contact with the lower part of the unit and fixed to the U-shaped plate, are reinforced by serving as strength members. Therefore, an air conditioner can be easily and inexpensively manufactured with a small number of parts without the need for a frame structure such as a support, and a thin and lightweight air conditioner can be completed.
