JPH0749870B2 - Air conditioner drain pan - Google Patents

Description

TECHNICAL FIELD The present invention relates to a drain pan for an air conditioner.

2. Description of the Related Art Conventional air conditioners are simplified in design by reducing the number of parts. A conventional air conditioner in this situation will be described below with reference to the drawings.

FIG. 4 shows the structure of a conventional air conditioner.
Reference numeral 1 is a ceiling-embedded air conditioner main body that is embedded inside the ceiling A of the air-conditioned room, and is a box body 2 that forms an outer shell and is embedded inside the ceiling A.
And the panel 3 exposed from the ceiling A surface. The panel 3 has an air suction port 4 in the rear part and an air discharge port 5 in the front part. Inside the main body 1, a heat exchanger 6 and a blower 7 are arranged, and a waterproof cover 8 is fixed to the blower 7 with screws or the like. The infiltration of drain water into the blower 7 and the drain at the bottom of the blower 7 Prevents corrosion by water.
Further, below the heat exchanger 6 and the blower 7, a drain pan 11 formed by simultaneous molding of the polystyrene foam 9 and the waterproof sheet 10 is installed, and drain water generated by the heat exchanger 6 is discharged from a drain port 12. Was.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a configuration, since the drain water generated from the heat exchanger flows into the lower part of the blower, it is necessary to form a waterproof sheet on the entire surface of the polystyrene foam. Requires a waterproof cover to prevent drain water from entering the blower and corroding the bottom of the blower due to drain water, which increases work time due to increased drain pan cost and an increase in the number of parts. It had a drawback.

The present invention solves such a conventional problem, and provides a drain pan having a simple structure and capable of drainage treatment without drain water flowing into the lower part of the blower.

Means for Solving the Problems In order to solve the above problems, the drain pan of the air conditioner of the present invention has a water channel on the heat exchanger side and a recess on the blower side.

Action The drain pan of the present invention has a water passage formed by simultaneously molding a waterproof sheet on the heat exchanger side, a concave portion on the blower side, and by separating the water passage and the concave portion, drain water does not flow into the blower side. Is.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a cross-sectional view of a ceiling-embedded air conditioner according to an embodiment of the present invention, in which reference numeral 1 is a ceiling-embedded air conditioner main body that is buried inside a ceiling A of an air-conditioned room. Is formed of a box body 2 embedded in the ceiling A and a panel 3 exposed from the surface of the ceiling A. The panel 3 has an air suction port 4 at the rear part and an air discharge port 5 at the front part. A heat exchanger 6 and a blower 7 are disposed inside the main body 1, and a drain pan 8 is installed below the heat exchanger 6 and the blower 7.

FIG. 2 is a perspective view of the drain pan 8, and FIG. 3 is a cross-sectional view of the drain pan 8. The drain pan 8 is formed by simultaneous molding of the polystyrene foam 9 and the prevention sheet 10, and is located below the heat exchanger 6. Is a waterway whose surface is covered with a waterproof sheet 10 1
1, and a recess 12 is formed below the blower 7,
A drain port 13 is provided at the end of the water channel 11.

As described above, according to this embodiment, in the drain pan 8 located below the heat exchanger 6 and the blower 7, the water channel 11 whose surface is covered with the waterproof sheet 10 below the heat exchanger 6, and the blower. 7
By forming the concave portion 12 below and separating the water passage 11 and the concave portion 12, drainage treatment can be performed without flowing drain water generated from the heat exchanger 6 to the lower side of the blower 7.

EFFECTS OF THE INVENTION As described above, the present invention provides the drain pan with the water passage whose surface is covered with the waterproof sheet in the lower part of the heat exchanger, and the concave part in the lower part of the blower, so that the drain water does not flow to the lower part of the blower. By performing drainage treatment, drain water does not enter the blower, corrosion due to drain water at the bottom of the blower is eliminated, and the waterproof sheet is molded only in the lower part of the heat exchanger, so the number of parts can be reduced. It has various advantages such as simplification of the assembly man-hour and cost reduction.
