Description

[Detailed description of the invention] Industrial application field The present invention is equipped with a dew pan made of a molded heat insulating material such as styrofoam, and a protective cover is placed along the surface of the dew pan to protect the dew pan from the heat of the auxiliary heater. Regarding the installed air conditioner.

Conventional configuration and its problems That is, as this type of air conditioner, the one shown in FIG. 1 is common. In this figure, 1 indicates the indoor unit body of the ceiling-suspended air conditioner, upper plate 2,
The outer shell is composed of a lower plate 3, side plates 4, rear plate 5, etc. Inside the main body 1, a front heat exchange chamber 7 is separated by a partition plate 6.
and a rear ventilation chamber 8. The ventilation chamber 8 is equipped with a suction grill 9 that can be freely opened and closed, a blower 10, etc. on the lower surface, and the heat exchange chamber 7 has an air outlet 11 at the front, an air outlet grill 12, a wind direction plate 13, and an auxiliary heater 1 for heating.
4, a heat exchanger 15 etc. are arranged respectively. 1
Reference numeral 6 denotes a dew pan made of styrofoam into a predetermined shape, and is placed along the entire lower part of the heat exchange chamber 7, that is, along the lower plate 3 from the air outlet 11 to the partition plate 6. The front rising portion 16 of this dew pan 16
The air outlet side of a is formed in an arcuate shape, and cooperates with the wind direction plate 13 to generate a wall effect, so that the air is blown downward at a steeper angle. The surface of this dew pan 16 is covered with a dew pan 16.
A protective cover 17 is provided to protect the auxiliary heater 14 from the heat of the auxiliary heater 14, and this protective cover 17 has a front end 17a attached to the front bent flange 3a of the lower plate 3 with screws 1.
It is fixed at 8. The occurrence of a gap P between the protective cover 17 and the condensation tray 16 was unavoidable from the viewpoint of the precision of the individual molding dimensions and the ease of assembly.

However, in such a configuration, when dehumidified water accumulates in the dew pan 16, it is drained from the main body 1 through a drain pipe (not shown).
It is designed to be drained outside, but there is a drain tray 16.
Dehumidified water also enters the gap P between the front surface and the back surface of the protective cover 17, and this water also enters the sloped part 16b and the rising part 16a of the dew pan 16 due to capillary action, and thus leaks to the outside of the dew pan 16. had.

Purpose of the invention Therefore, the present invention has been made with the object of preventing the capillary phenomenon caused by the gap between the protective cover and the dew pan, thereby preventing dehumidified water from leaking to the outside of the dew pan.

Structure of the invention In order to achieve this object, the present invention is designed to form a dew pan or a protective cover such that a gap larger than the capillary phenomenon is formed between the dew pan or the protective cover at the rising part or the inclined part of the dew pan or the protective cover. A convex portion is formed on the protective cover to solve the above-mentioned conventional drawbacks.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. Note that the structure of the indoor unit, the presence of the dew pan, and the protective cover are the same as in FIGS. 1 and 2, and only the main parts that differ in structure will be described.

In FIG. 3, the dew pan 16 has a surrounding rising portion 16a and an inclined portion 16b formed within the dew pan 16, and the rising portion 16a has an arcuate side on the outlet side. Furthermore, a protrusion 16c (protrusion) is formed on the inclined portion 16b and protrudes toward the inside of the water tray. The protective cover 17 is formed along the surface shape of the dew pan 16 excluding the convex stripes 16c, and the flat part 17b is adhesively fixed to the bottom surface of the dew pan 16 with double-sided adhesive tape or the like, and the front end is attached to the lower plate as shown in FIG. It is fixed to the bent flange 3a of No. 3 with screws.

Therefore, the protrusion 16c formed on the sloped part 16b of the dew pan 16 comes into contact with the sloped part 17c of the protective cover 17, and a gap 1 is formed. The protruding strip 16c is set so that the gap l is wide enough to prevent capillary action from occurring.
The height of the dehumidifying water is preset to prevent dehumidifying water from leaking to the outside of the dehumidifying tray 16.

Furthermore, the same effect can be obtained not only in the above-mentioned configuration but also in the case where the protruding strip 17d is formed on the sloped part 17c of the protective cover 17 and brought into contact with the sloped part 16c of the dew pan 16 as shown in FIG. Needless to say.

Effects of the invention As is clear from the above explanation, according to the present invention, a predetermined gap is formed between the dew pan and the protective cover by the convex parts, so that dehumidified water does not leak out of the dew pan due to capillary action. In addition, since the convex portion is formed on the inclined portion or the rising portion of either the dew pan or the protective cover, it goes without saying that the capillary phenomenon is prevented, and the combination of the two provides a stable assembly with less wobbling.
