Description

Description: TECHNICAL FIELD The present invention relates to an air conditioner, more specifically, an air conditioner main body is provided in a ceiling, an opening is provided in an opposing ceiling portion, and the air conditioner is provided in the ceiling. Regarding air conditioners.

[Prior Art] The lower end of the blower mounting plate housed in the main body case of the conventional ceiling-embedded air conditioner is only bent at a right angle, and the blower is stopped for a long time under hot and humid conditions. When continuous cold water is passed, condensed water is generated on the surface of the fan mounting plate where the warm air in the room contacts the cool air in the heat exchanger, and the condensed water in the room falls through the panel mounted at the bottom of the main unit case. There was a drawback. Incidentally, as related devices of this type, there are SAIkai 59-136518 and SAIkai 60-2215.

[Problems to be Solved by the Invention]

The above-mentioned conventional technology stops the blower for a long time under high temperature and high humidity conditions, and when cold water is continuously passed, dew water is generated on the blower mounting plate surface where the warm air in the room and the cold air generated from the heat exchanger come into contact with each other, No consideration was given to the fall of the condensed water, and there was a problem that the condensed water fell into the room through the panel attached to the lower portion of the main body case and having the inlet and the outlet.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent the dew condensation water generated on the surface of a blower mounting plate from falling into the room, which is a problem of the above-mentioned prior art.

[Means for Solving the Problems]

The above object is to bend the lower end of the blower mounting plate obliquely upward to form a V-shaped groove, provide a plurality of drain holes in the V-shaped groove, and provide a water receiving plate on the lower surface of the V-shaped groove of the blower mounting plate. This is achieved by providing a water tray under the water receiving plate.

[Action]

When the blower is stopped for a long time under high temperature and high humidity conditions and cold water is continuously supplied, the warm air in the room comes into contact with the cool air generated from the heat exchanger. The water flows down to the V-shaped groove where the lower end of the blower mounting plate is bent obliquely upward, and the dew condensation water passes through a plurality of drain holes provided in the V-shaped groove, and the water receiving plate attached to the lower surface of the V-shaped groove is used. Water drops can be prevented from falling into the room because it flows down to the water pan through the water.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 is a main body case, and 2 is a bottom panel that closes the bottom of the main body case 1. The main body case 1 is suspended from an upper ceiling 6A by a suspension bolt 4 which is passed through a seat 3 on the upper surface thereof and a nut 5 which is screwed to the suspension bolt 4, and faces the opening 7 opened in the lower ceiling 6B. It is located inside the ceiling. The panel 2 has a chamber die 8 provided with a suction port and a blowout port in the upper part, is screwed to the lower part of the main body case 2, and closes the opening 7 of the lower ceiling 6B. Further, the panel 2 is provided with an air inlet 9 and an air outlet 10 which communicate with the chamber die 8.

A blower 11 is provided in the main body case 1, a heat exchanger 12 for exchanging heat supplied from the blower 11 into hot air or cold air via hot water or cold water, and a partition plate 13 below the heat exchanger 12. Further, a water tray 14 is arranged below the partition plate 13.

Reference numeral 15 denotes a blower mounting plate of the present invention, which is fixed to the side surface of the main body case 1 by screwing, the blower 11 is attached to the surface, and the lower end is bent obliquely upward to form a V-shaped groove 16,
The V-shaped groove 16 is provided with a plurality of drain holes 17.
A water receiving plate 18 communicating with the water receiving tray 14 is attached to the lower surface of the V-shaped groove 16, and a heat insulating material 19 is provided on the lower surface of the water receiving plate 18. 20 is a room to which cold and hot air is supplied.

〔The invention's effect〕

According to the present invention, the lower end of the blower mounting plate is bent upward to form the V-shaped groove, the V-shaped groove is provided with a drain hole, and the water receiving plate communicating with the water tray is attached to the lower surface of the V-shaped groove. Due to the configuration, the condensed water on the surface of the blower mounting plate that occurs when the blower is stopped for a long time under high temperature and high humidity conditions and cold water continues to flow down into the V-shaped groove, and the drain hole of the V-shaped groove And flows into the water tray through the water tray. Therefore, the dew condensation water generated on the surface of the blower mounting plate does not drop into the room.
