DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner which collectively discharges drain water from a bottom plate.

[0002]

2. Description of the Related Art Conventionally, a bottom plate of an outdoor unit of an air conditioner is provided with a plurality of drain outlets as shown in Japanese Utility Model Publication No. 59-12530 to drain drain water collected in the bottom plate. It has been proposed to improve the properties.

[0003]

As described above, when a plurality of drain outlets are provided on the bottom plate of the outdoor unit, the drain water flows out from a plurality of locations on the bottom plate, and the area around the outdoor unit is flooded with drain water over the entire surface. Was sometimes
Also, it was considered that the height of the bottom plate was increased by changing the height of the drain outlet to drain the drain water from a specific (lowest position) drain outlet. It is not suitable for outdoor units with a large bottom plate area, such as packaged air conditioners.

[0004] It is an object of the present invention to ensure that drain water can be discharged from one place even if the area of the bottom plate is large.

[0005]

In order to achieve this object, the present invention provides a support leg which is movable in an installed state of a housing of an air conditioner, and moves the support leg to move the support surface and a bottom plate. And a drain pan accommodated in the space.

[0006]

[0007]

The drain is dropped from a plurality of drain pans on the bottom plate of the air conditioner by moving the support legs and storing the drain pan in the space between the installation surface and the bottom plate in a state where the housing of the air conditioner is installed. Water is collected in a drain pan and flows from a single outlet.

2 to 4, reference numeral 1 denotes an outdoor unit (air conditioner) of a package type air conditioner, the outer dimensions of which are about 1 m50 cm and a depth dimension L.
Is about 75 cm, and the depth dimension W _{1 in} front is about 1 m 50 cm
Then, as going from the middle to the back, the depth dimension W ₂
Are sequentially reduced (see FIG. 3).

Numerals 2 denote blowers arranged in the upper part of the outdoor unit 1, which are respectively connected to driving motors (not shown). 3 is a fan guard for covering this fan. 4
Is an electrical box, and 5 is a soundproof cover, in which a scroll compressor (not shown) is housed. Reference numeral 6 denotes an accumulator, 7 denotes a four-way valve, and 8 denotes a connection valve. These devices are housed in the outdoor unit 1. Reference numeral 9 denotes a bottom plate of the outdoor unit 1, and leg pieces 10 are fixed to four corners thereof. Reference numeral 11 denotes a heat exchange device, which is a plate-fin type heat exchanger 12, which is bent in a substantially U-shape (more precisely, the front side is open and the width of the front side is larger than the width of the back side). 13 are stacked.

The rear surface 14 of the outdoor unit 1 and the rear portions of the inclined left and right side surfaces 15 and 16 are formed by the heat exchange device 11, and the heat exchange device 11 functions as a strength member of the outdoor unit 1. .

The reason why the two plate fin type heat exchangers 12 and 13 are stacked in this way is that the height H of the outdoor unit 1 is as high as about 1 m50 cm, so that a plate having such a height is used. This is because it was difficult to integrally manufacture the fin type heat exchanger in terms of equipment. The structure of the combination of the two heat exchangers 12, 13 will be described later.

Since the outdoor unit 1 is configured to have such an appearance, even if a plurality of these outdoor units 1 are arranged and installed as shown in FIG. Since the suction space 17 is formed in each of the outdoor units 1, a sufficient amount of suction air can be secured in each outdoor unit 1. FIG. 2 shows a state in which the front panel and the right side panel are removed for convenience of explanation.

FIG. 1 is a perspective view of the bottom plate 9. Reference numeral 20 denotes a water receiving portion in which a part of the bottom plate 9 is stepped down.
It is a drain outlet provided in. Thus, the water receiving part 2
0 and many drain outlets 21 are provided because the width W1 of the bottom plate 9 is about ₁ m40 cm and the depth L is about 75 cm.
This is because there is a possibility that drain water on the bottom plate 9 cannot be reliably drained only by providing one drain outlet 21. In particular, the outdoor unit 1 is not installed horizontally (the drain side is installed higher than the anti-drain side).
In such a case, there is a possibility that the drain water accumulates in the bottom plate 9 and the bottom plate 9 is rotten.

Therefore, even if the bottom plate 9 is installed in a slightly inclined state by providing a large number of water receiving portions 20 and the drain outlet 21 of the bottom plate 9. Drain water is dropped downward from the drain drain port 21 which is the lowest. Reference numeral 22 denotes a drain pan placed between the leg pieces 10 below the bottom plate 9. A single drain port 23 (hereinafter referred to as “drain pipe”) is provided on one side thereof. This drain pan 22
Has a lower surface inclined toward the drain pipe 23.

The leg piece 10 described above is bent so that its longitudinal section is substantially U-shaped. Reference numeral 24 denotes a locking piece (engaging portion) bent downward, the tip of which protrudes outward from the bottom plate. 25 is this leg piece 10 to the bottom plate 9
The locking piece 24 and the screw hole 25 are provided on the upper surface 28 of the leg 10. 26
Is an elliptical engagement hole (engagement portion) provided on the vertical surface of the leg piece 10. Reference numeral 27 denotes a mounting hole to be inserted into an anchor bolt or the like projecting upward from the installation surface of the outdoor unit 1, and is provided on the lower surface of the leg piece.

Then, after the outdoor unit 1 is placed on the installation surface, two screws screwed into the screw holes 25 are removed from above the bottom plate 9 so that the leg pieces 10 as shown by solid arrows in FIG. Can be rotated about one mounting hole 27. At this time, even when the leg 10 is rotated, the upper surface 28 of the leg 10 is kept on the bottom plate 9.
After rotating the two leg pieces 10 in this way,
When the drain pan 22 is inserted below the bottom plate 9 along 0, the drain pan 22 is located below the drain drain port 21 provided on the bottom plate 9 and even if drain water drops from any drain drain port 21, the drain pan 22 You can receive it. The drain water received by the drain pan 22 is collected and flows out from the drain pipe 23 (see FIG. 6).

FIG. 7 shows a state in which a lifting wire is hung on the outdoor unit 1 in the left-right direction, and FIG. 8 shows a state in which a lifting wire is hung on the outdoor unit 1 in the front-rear direction. As shown in FIG. 7, if the lifting wire 30 is hung so as to straddle the locking pieces 24 of the left and right leg pieces 10 to lift and suspend the outdoor unit 1, the worker Is located in the front space A and the rear space B of the outdoor unit 1 and can perform this operation. Therefore, the space of the installation place of the outdoor unit 1 is
Spaces A and B before and after left space C and right space D
Is more suitable for larger cases.

On the other hand, as shown in FIG. 8, if the outdoor unit 1 is hung by hanging a wire 31 for lifting so as to penetrate through the engaging holes 26 of the front and rear leg pieces 10, the hanging is performed. The operator can perform this operation by being located in the left space C or the right space D of the outdoor unit 1. Therefore, this is suitable when the installation space of the outdoor unit 1 is larger in the left and right spaces C and D than in the front space A and the rear space B.

As described above, in any lifting, the two leg pieces 10 adjacent to the lifting wires 30 and 31 are connected.
The wires 30 and 31 need only be two, and the number of wires 30 and 31 is smaller than in the conventional case (four), and the lengths of the wires 30 and 31 are made uniform. Thus, it is possible to easily balance the lifting of the outdoor unit 1. Moreover, as described above, it is possible to select a method of hanging the wires 30 and 31 according to the size of the installation space, so that the work can be easily performed.

FIG. 9 shows two plate-fin heat exchangers 1.
Reference numerals 2 and 13 indicate a combined state, and reference numeral 40 denotes a positioning member of both heat exchangers, which is configured to be vertically inverted. That is, 41 is a first locking piece bent downward at both ends of the front edge, and 42 is a second locking piece bent downward at the center of the rear edge.
, 43 is a third locking piece bent downward at the right edge, 44 is a fourth locking piece bent upward at the center of the front edge, and 45 is bent upward at both ends of the rear edge. The fifth locking piece 46 is a sixth locking piece bent upward at the left edge. 47 is an opening provided in the horizontal piece. Reference numeral 48 denotes a cushion material placed on the upper surface of the lower heat exchanger, and an opening 49 is provided at a position corresponding to the opening of the horizontal piece.

Here, when such a heat exchange device 11 is incorporated in the assembly line of the outdoor unit 1,
The lower heat exchanger 3 is placed on the bottom plate 9, and then a cushion member 48 is laid on the upper surface of the heat exchanger, and then the positioning member 40 is attached from above the cushion member 48. As a result, the upper edge of the lower heat exchanger 13 is fitted into the first and second locking pieces 41 and 42, and the third locking piece 43 is fitted.
Are inserted between the fins 50. The upper heat exchanger 12 is placed with the positioning member 40 attached to the upper edge of the lower heat exchanger 13 in this manner. As a result, the lower edge of the upper heat exchanger 12 is fitted with the fourth and fifth locking pieces 44 and 45, and the sixth locking piece 46 is connected to the upper heat exchanger 12.
Between the fins 51.

After the positions of the heat exchangers 12 and 13 are determined by the positioning member 40, the tube sheets of the heat exchangers are fixed to each other by metal fittings (not shown). This makes it possible for the two heat exchangers 12, 13 to be integrally molded. Also, a blower 2 and a scroll compressor built in the outdoor unit 1 (see FIG. 2)
Even if the vibration of the operation is transmitted to the heat exchange device 11, since the heat exchange device 11 is fixed by the tube sheets and the positioning member 40, the heat exchangers 12 and 13 are displaced, and Can be reduced.

[0024]

As described above, according to the present invention, a support leg which is movable in a state where the casing of the air conditioner is installed is provided, and the support leg is moved to be accommodated in the space between the installation surface and the bottom plate. Drain pans are provided and drains dropped from a plurality of drain pans on the bottom plate of the air conditioner are collected by the drain pans and collectively flow from a single drain port. The drain water can be smoothly drained from the bottom plate to this drain pan even if the bottom plate is installed with a slight inclination, and the bottom plate can be made hard to rot. In addition, since the drain water flows out from the single drain port, it is possible to prevent the area around the air conditioner from being flooded with the drain water as in the related art without the drain pan.
