Description

[Detailed Description of the Invention] This invention relates to a ceiling-mounted air conditioner, and particularly relates to an improvement in measures against condensation on a lower blowing vane.

As shown in FIG. 3, a conventional downward blowing device of this type of air conditioner has a structure in which a downward blowing grill 9 and a downward blowing vane 10 are attached to the outer wall 7 on the lower surface side, and when the downward blowing vane 10 is opened and closed, A portion of the air is blown into the lower part of the outer casing 1, and when the outer casing 1 is closed, all the air is blown out to the front from the front blowing grill for air conditioning.

In this case, when the lower blowing vane 10 is closed and during cooling operation, the lower blowing vane 10 is exposed to the cold air A, is cooled, and comes into contact with the high temperature indoor air outside the outer casing, causing dew to form on the lower surface of the lower blowing vane 10. Eventually, water droplets fall into the room from the downward outlet grille 9 and wet the floor.

In order to prevent this, the bottom blowing vanes are flocked with hair, etc. to soften the dew on the vanes, diffuse the dew and prevent the water from falling. It had the disadvantage of not being sufficient.

This invention was made to eliminate this drawback, and has a downward blowing grill on the outer wall on the lower side,
When the downward blowing is stopped, the rotating position of the downward blowing vane is set to be parallel to the downward blowing grille, and a space is created between the downward blowing grille and the downward blowing vane to prevent water droplets from adhering to the downward blowing vane. The purpose is to

This invention will be explained in detail below with reference to embodiments shown in FIGS. 1 and 2.

Reference numeral 1 designates an outer casing of an air conditioner, which includes a front outlet grille 2 on the front, an outer wall 6 on the top side, and an outer wall 12 on the rear side.
The inside of this outer casing is divided into a suction chamber 14 and a blowout chamber 15 by a partition plate 13. 4 is a heat exchanger, and the above-mentioned blowing chamber 1
5 on the suction chamber 14 side. Reference numeral 5 denotes a blower, which is provided in the suction chamber 14 to send air to the blow-out chamber 15. Reference numeral 8 denotes a suction grill, which is provided on the lower surface of the outer casing between the outer wall 12 on the rear side and the partition plate 13. Reference numeral 16 denotes a wind direction changing louver, which is provided together with the electric heater 3 in the blow-off chamber 15 between the front blow-off grill 2 and the heat exchanger 4. Reference numeral 17 denotes a dew pan, and a heat insulating material 18 is provided on the outer wall 7 on the lower surface side to catch dew droplets attached to the heat exchanger 4 and the electric heater 3.
It is provided through. 19 is an electrical parts box,
It is provided on the outer wall 12 on the rear side near the suction grill 8 in the suction chamber 14 . 9 is a downward blowing grill, which connects the front blowing grill 2 and the heat exchanger 4;
It is provided on the outer wall 7 on the lower surface side between. 10
A lower blower vane is supported within the blower chamber 15 with a fulcrum 20 on one side of the front blower grille 2 so as to close the opening of the lower blower grille 9. 11 is a stopper, and the above-mentioned lower blowing vane 10
The heat exchanger 4 of the lower outlet grille 9 has the same length as the height of the fulcrum 20 and the lower outlet grille 9 so that the heat exchanger 4 of the lower outlet grille 9 is located parallel to the lower outlet grille 9.
It is installed on the side edge.

In this case, when there is a partial downward blowing, the downward blowing vane 10
is the position of the stopper 11, and air passes through the downward blowing grille 9 and is blown out to the lower part of the main body 1.
Furthermore, when the downward blowing is stopped, the position of the downward blowing vane 10 is parallel to the downward blowing grille 9, and the point B of the downward blowing vane 10 is set and abutted by the stopper 11, and there is no space between it and the downward blowing grille 9. , and the lower outlet grille 9 is not closed. Therefore, during downward blowing of the air conditioner, the cold air A passes above and below the downward blowing vanes 10, and the downward blowing vanes 10 are cooled, but since they do not come into contact with the high temperature indoor air, there is no dew on the vanes. .

With the above configuration, water falling from the main body due to dew on the downward blowing vanes during downward blowing during cooling operation can be prevented inexpensively and reliably without implementing expensive and unnecessary measures such as flocking. This effect is great because it can be prevented.
