Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention relates to a floor-standing packaged air conditioner, and particularly to a method for assembling the same.

(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 prior art Since the assembly sequence is to form a framework with columns to create a framework structure, and then to place and secure devices such as heat exchangers and blowers between the columns, this assembly process is difficult to assemble. It was carried out with a skeleton structure erected from the ground. For this reason,
The equipment was assembled by lifting it to overhead height, which made work difficult.In addition, as packaged air conditioners have become thinner in recent years, there is a risk of them falling over.To prevent this, air conditioner products are placed on the production line. Assembling and manufacturing equipment costs, such as installing a fall prevention frame for each, was complicated and the work was complicated.

(d) Purpose of the Invention The present invention provides a method for assembling an air conditioner that allows devices such as a heat exchanger and a blower to be safely and easily assembled into a housing, and also reduces the number of parts and reduces the weight. This is what we provide.

(E) Key Points of the Invention After opening a substantially U-shaped plate in cross section and storing and fixing equipment such as a heat exchanger and a blower in the U-shaped plate from the open surface of the U-shaped plate, the U-shaped plate is opened. The air conditioner is assembled by closing both end openings and the open surface with plate members, and by adopting this assembly method, equipment can be assembled and fixed with the U-shaped plate lying down.

(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 exchanger and a blower having widths that are approximately the same as the inner width of the U-shaped plate 1. An electric motor 35 with a suction fan 34 is fixed in position in a fan casing 38 made of sheet metal with an open back via support legs 36 and a nozzle plate 37, and each is assembled in advance as a unit. Reference numeral 39 denotes a fitting that is fixed to a hanging piece 40 provided at the upper end of the heat exchanger 31 and formed integrally with the upper surface flange portion 24c through screw holes 41 and 42; 43 is a mounting flange piece 3;
A hole 45 extending over the recesses 44a and 44b of a and 3b and fixing the drain pan 33 is spot welded along the scroll part 46 of the fan casing 38, and is also fixed with a screw hole 47 in the back part 23 and a welding bolt 48. multiple mounting pieces.

Therefore, the order of assembling the air conditioner is to first lay down the bent plate 1 with a generally U-shaped cross section as shown in FIG. Put your hands on the mounting flange pieces 3a and 3b and push open the U-shaped plate 1 in the left and right direction to open the open surface 2.
is expanded to the inner width dimension of the U-shaped plate 1. In this expanded state, the blower 32, which has been made into a unit in advance, is stored from the open surface 2, and the mounting piece 45 is attached to the weld bolt 48.
After fixing to the unit heat exchanger 3
1 from the open surface 2, and apply the sheet metal drain pan 33 with the heat insulating material 49 to the ventilation guide plate 50, and fix the heat exchanger 31 and the drain pan 33 with the screws 51 and 33, respectively.
52 stop. Then, the U-shaped plate 1 is attached to the left and right side parts 2.
The screw 53 is fastened from the outside of the rear back part 23 which is laid down so that either one of the parts 1 and 22 is facing down.

After that, after fixing the upper plate member 17 and the lower plate member 18 with screws 54, the main plate 13, which is the front plate member 5, is fixed with screws 55, and the inclined lower edge 56 is fixed with the lower plate member 1.
8 and fix the auxiliary plate 16 with the screws 57, the assembly is completed. In addition, the screw 55 exposed to the front,
If 57 is covered with a makeup sash (not shown), the beauty 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 58a, 58b, 58c, and 58d formed by mounting flange pieces 3a and 3b. Therefore, it can be used as a member with sufficient strength to support equipment such as the heat exchanger 31 and the blower 32 when installed on the floor in an upright state. The drain pan 33 spanning both side surfaces 21 and 22 is reinforced in the left and right direction, and this drain pan 33
The heat exchanger 31 in an inclined state straddles the upper end of the back part 23 and the fan casing 38 for the blower 32 which straddles the drain pan 33 and the lower part of the back part 23 are reinforced with bracing, respectively, to reinforce these devices. It can be made into a structure with increased strength that also serves as a member.

(G) Effects of the Invention According to the method of the present invention, equipment such as a heat exchanger and a blower can be installed while the plate having a substantially U-shaped cross section is laid down, so assembly work can be carried out safely and installation of these equipment can be simplified. Storing can be easily done by simply opening the U-shaped board and widening the open surface. Moreover, the U-shaped board can be kept lying down until the assembly process, in which the openings at both ends and the open surface of the U-shaped board are closed with plate members, is completed. It is easy to assemble, and is particularly suitable for assembling slim floor-standing package air conditioners.

Moreover, in addition to the strength of the approximately U-shaped cross-sectional plate itself, the equipment that is housed within the approximately full width dimension within this U-shaped plate is assembled into a strong structure that also serves as a reinforcing member, eliminating the need for frame structures such as columns. It is possible to manufacture a thin and lightweight air conditioner at low cost with a small number of parts.
