DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated pedestal for an air conditioner, and more particularly, to an air conditioner which is disposed at a lower portion, that is, on a floor surface when an air conditioner for circulating indoor air is installed. It relates to a heat insulating mount.

[0002]

2. Description of the Related Art The base of a conventional air conditioner has been
No. 149709. The gantry 1 shown in FIG. 9 includes a rectangular frame 2 made of a channel steel, and a plate-shaped drain pan 3 that is inclined downward substantially toward the center is disposed in the frame 2. A hole 3a is formed at substantially the center of the drain pan 3, and the lower end of the hole 3a is connected to the other end of a drain pipe 4 whose tip extends from one side of the frame 2 to the outside. Condensed water or the like generated in the air conditioner flows on the drain pan 3 and is discharged from the drain pipe 4.

[0003]

In the conventional gantry 1, the frame 2 is formed from a channel steel. However, since the channel steel is very heavy, workability in manufacturing or installing the gantry 1 is poor. There was a problem. In addition, when the air conditioner is operating, the cool air or hot air flowing through the cabin and supplied to the indoor space to be air-conditioned is transmitted to the frame 2 and the drain pan 3, causing heat loss and the like. In some cases, dew condensation easily occurs outside the gantry 1.

[0004] Therefore, a main object of the present invention is to provide an insulated mount for an air conditioner that can be easily manufactured and installed, and hardly causes dew condensation.

[0005]

Means for Solving the Problems] The present invention, insulation panels by placing the air conditioner of the casing that have a heat-insulating panels
A direct fixed to insulate frame and a metal plate, or
Top part and the side bent downward from the periphery of this top part
Fold the edges of the face and side faces in parallel with the top face
Comprises bending the box and a lower surface, and a box inside provided and the lower surface portion foam insulation that will be supported by the,
It is a heat-insulating mount for an air conditioner.

[0006]

The rigidity of the frame is enhanced by foaming a hard urethane resin, for example, inside the box. Therefore, the weight of the frame is lighter than that of a frame having a conventional channel steel frame. In addition, since the urethane foam resin is a heat insulating material, cold air or hot air prepared in the air conditioner during operation of the air conditioner is blocked by the heat insulating material, and heat loss to the outside of the gantry is reduced.

[0007]

According to the present invention, since the gantry can be reduced in weight, the workability in manufacturing or installing the gantry can be improved. In addition, since heat loss and the like from the gantry portion of the air conditioner can be reduced, dew condensation hardly occurs at that portion. The above and other objects, features and advantages of the present invention are:
It will be more apparent from the following detailed description of embodiments, which proceeds with reference to the accompanying drawings.

Further, as can be clearly understood from FIG. 5, the heat insulating gantry 12 disposed at the lower portion of the coil casing 18 has an opening on the upper surface of the box 22 of the heat insulating gantry 10 having a shape similar to the upper surface and having a slightly smaller shape. 26a is formed. A drain pan 30 which is a tray with a slope is provided in the opening 26a. Drain pan 3
No. 0 is formed by bending a steel plate so as to extend downward from one side to the center of the opposite side of the upper surface of the box body 26, and has a drain port 30a formed at the lower end thereof.

As shown in FIG. 6, an opening 26b having a shape slightly larger than the outer edge of the upper surface of the drain pan 30 is formed on the lower surface of the box 26. When assembling the box 26 and the drain pan 30, the drain pan 30 is arranged on the opening 26a side from the opening 26b below the box 26, and the outer edge of the drain pan 30 is fixed to the edge of the opening 26a by welding or the like. I do. A drain pipe 32 is inserted into one side of the box 26 corresponding to the drain port 30a of the drain pan 30, and the drain port 30a is passed through the side face.
Linked to Then, from the opening 26b below the box 26 to which the drain pan 30 is fixed, a heat insulating material 24 made of urethane resin that is hard and has good adhesion to a steel plate as in the heat insulating gantry 10 shown in FIG. Formed and insulated gantry 1
2 secures sufficient strength to support the casing 18.

At both ends of two opposing sides of the heat insulating gantry 10 and 12 having such a structure, fixing brackets 34 for fixing to a floor surface or the like are respectively attached. When installing the air conditioner 14 using the heat-insulating mounts 10 and 12, referring to FIG. 7, first, the casings 16, 18 and 20 are placed on the heat-insulating mounts 10 and 12, respectively.

Are disposed on the coil casing 18 side.

Inside the coil casing 18, a heat exchange coil 44 and a humidifier 46 are arranged in this order from the filter casing 16 side. An air supply port 48 is formed on the upper surface of the fan casing 20 connected to the coil casing 18 on the opposite side of the filter casing 16. A fan 50 connected to the air supply port 48 and an electric motor 52 connected via a belt (not shown) to operate the fan 50 are arranged inside the fan casing 20. Then, the return air port 40 and the air supply port 48 of the air conditioner 14 are communicated with a room to be air-conditioned through a duct (not shown).

When the blower 50 is operated by the electric motor 52, air from the indoor space to be air-conditioned is taken into the filter casing 16 from the return air port 40 through the duct. Then, after this air is removed through the pre-filter 42a and the main filter 42b, the air is cooled or heated to a required temperature through a heat exchange coil 44 composed of a cooling coil and a heating coil, and is humidified as needed through a humidifier 46. Is done. The air subjected to such necessary air conditioning is sucked into the blower 50 and supplied from the air supply port 48 to the indoor space to be air conditioned via the duct.

Referring to FIG. 8, a part of the cool air or the hot air of the air-conditioned air flowing through the lower part of the air conditioner 14 when the air conditioner 14 is operated is insulated by the heat insulating pedestal provided at the lower part of each of casings 16, 18 and 20. It conducts to the upper surfaces of 10 and 12 and then further to the outside. However, the lower portions of the heat insulating panels 16a, 18a and 20a of the casings 16, 18 and 20 are directly attached to the side surfaces of the heat insulating frames 10 and 12, and the heat insulating material 24 is disposed inside the boxes 22 and 26. Therefore, the conduction of the cool air or hot air is cut off, and the heat loss of the air conditioner 14 is reduced. Condensed water and the like generated in the air conditioner 14 flow on the drain pan 30 of the heat insulating gantry 12 disposed below the coil casing 18, and are discharged from the drain pipe 32.

According to this embodiment, the boxes 22 and 26
The gantry can be reduced in weight by increasing the rigidity of the gantry by foaming a heat insulating material 24 made of a hard urethane resin inside the gantry, so that the workability during production and installation can be improved. Further, since heat loss from the lower part of the air conditioner 14 can be reduced, the occurrence of dew condensation can be prevented. In the above-described embodiment, the case where the heat insulating material 24 is formed by foaming a hard urethane resin is shown. However, other known materials that can be used as foam heat insulating materials include, for example, styrene resin,
