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, columns with an L-shaped cross section are erected and fixed at the four corners of the bottom box, and then 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 A bottom box and five panels are required as components of the casing, and in order to assemble these panels and install equipment such as a heat exchanger and blower, it is necessary to straddle four columns and the columns. Since the frame structure was made up of multiple angle frames, the number of parts was large, the assembly was complicated, and the manufacturing cost was relatively high.

(d) Object of the Invention The present invention provides an inexpensive and lightweight air conditioner that reduces the number of components of the casing and eliminates the need for frame parts such as columns.

(E) Key Points of the Invention A casing consisting of a substantially U-shaped plate in cross section with one side open, a plate member that closes openings at both upper and lower ends of the casing, and the open surface, respectively; consists of a heat exchange unit fixed to the U-shaped plate, and a blower unit abutting the lower part of the unit and fixed to the U-shaped plate,
In addition to the strength of the U-shaped plate itself, the heat exchange unit and air blower unit housed within the casing are reinforced by serving as strength members.

(f) Embodiments of the invention Examples of the invention will be described based on the drawings.
In Fig. 1, numeral 1 designates a substantially U-shaped plate in cross section, which has a pair of left and right mounting flange pieces 3a, 3b on the open surface 2 side, and is made of a single thin sheet metal with a wall thickness of 0.6 mm.
It is used as the main component of the casing 4, which is bent into a slim shape with a width of 1870 mm, a width of 540 mm, and a depth of 175 mm.

5 is a screw hole 6 of the mounting flange pieces 3a, 3b.
A front plate member with holes 7a and 7b corresponding to holes 7a and 6b, and an air outlet 9 with a wind direction change plate 8 and a grille 10.
It is divided into two parts: a main plate 13 having a suction port 11 and an operation control operation section 12; and an auxiliary plate 16 which is attached and detached when inserting an air filter 14 or inspecting an electrical equipment box 15, and which closes off the open surface 2. It is something.

17 and 18 are openings 1 at both upper and lower ends of the U-shaped plate 1
9 and 20, the upper plate member 17
The upper flange piece 24 is formed by bending the upper ends of the left and right side parts 21 and 22 and the upper end of the back part 23 of the U-shaped plate 1.
a, 24b, 24c through screw holes 25, 26, respectively, and the box-shaped lower plate member 18 has the lower ends of the left and right side parts 21, 22 and the lower end of the back part 23 folded inward into an inverted L shape. Curved step portions 27a, 27
The screw holes 29, 3 are fitted along the outer surfaces of the screw holes 29, 3 with the overhanging pieces 28 in contact with the stepped portions.
It is designed so that even 0 can be installed.

Reference numerals 31 and 32 denote a heat exchange unit and a blower unit having widths that are approximately the same as the inner width of the U-shaped plate 1, and the heat exchange unit 31 is a unit block with a drain pan 34 fixed in advance to the lower end of the heat exchanger 33. As shown in FIG.
The electric motor 36 with 5 support legs 37 and the nozzle plate 38
Sheet metal fan casing 39 with open back via
Each is preassembled as a unit block with a fixed position inside. 40 is a tube plate 41 of the heat exchanger 33
A mounting tool 45 is fixed to a hanging piece 42 provided at the upper end and bent integrally with the upper surface flange piece 24c through screw holes 43 and 44, and a fitting 45 straddles the recesses 46a and 46b of the mounting flange pieces 3a and 3b. The holes 46 for fixing the drain pan 34 are spot welded along the scroll portion 47 of the fan casing 39 and are connected to the screw holes 48 and weld bolts 49 in the back surface 23.
These are a plurality of mounting pieces that are fastened together.

Therefore, to assemble the air conditioner, first, as shown in FIG.
Lay it down so that the open surface 2 is slightly expanded to the left and right as shown by the dashed-dotted line in FIG. After fixing to the bolts 49, the unit block heat exchange unit 31 is stored from the open surface 2, the drain pan 34 is applied to the ventilation guide plate 50, and the fixture 40 is attached to the hanging piece 42.
At the same time, fix the left and right front parts of the drain pan 34 to the recesses 46 of the front flange pieces 3a and 3b.
A and 46b are straddled and fastened with screws 52, thereby fixing the heat exchange unit 31 within the U-shaped plate 1 in a braced manner. The U-shaped plate 1 is then laid down so that one of the left and right side parts 21 and 22 is on the bottom.
Fasten with screw 53 from the outside.

After that, after fixing the upper plate member 17 and the lower plate member 18 with screws 54, the electrical equipment box 15 is housed in the housing 4 from the open surface 2, and its lower end is connected to the lower plate member 18, and its upper end is connected to the fan. Screw 5 to casing 39
5 to reinforce and support the blower unit 32. Then, the main plate 13, which is the front plate member 5, is fastened with the screws 56, the inclined lower edge 57 is locked with the lower plate member 18, and the auxiliary plate 16 is fastened with the screws 58, thereby completing the assembly. Note that if the screws 56 and 58 exposed to the front are covered with a decorative sash (not shown), the aesthetic appearance will not be impaired.

The air conditioner thus completed has a substantially U-shaped cross-sectional plate 1 formed of a strong single plate having a total of four corners 59a, 59b, 59c, and 59d formed by mounting flange pieces 3a and 3b. Because of this, the heat exchange unit 3 when placed vertically on the floor
1 and the blower unit 32, etc., and can also be used as a member with sufficient strength to support devices such as the U-shaped single plate 1. In addition, the drain pan 34 spanning the left and right side surfaces 21, 22 of the substantially U-shaped single plate 1 can be used to Reinforcement is also provided by the inclined heat exchanger 33 that straddles the drain pan 34 and the upper end of the back surface 23, and the fan casing 39 of the blower unit 32 that straddles the drain pan 34 and the lower part of the back surface 23, respectively. Reinforcement is carried out,
It is possible to create a structure with increased strength in which these devices also serve as reinforcing members.

(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 comes into contact with the lower part of the unit and is fixed to the U-shaped plate, are also reinforced 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.
