Description

[Detailed Description of the Invention] This invention relates to an air conditioner installed near the indoor ceiling,
In particular, in order to meet the request to minimize the feeling of pressure on the occupants, the design aims to create a flat shape, form an efficient ventilation path, and improve the productivity of the outer casing. It is.

The present invention will be described in detail below with reference to the embodiments shown in FIGS. 1 to 3. Reference numeral 1 denotes an upper panel forming the outer casing of the air conditioner, which has an opening at the bottom and an air outlet 2 at the front; Air suction ports 3 are provided on both sides and the back.

A lower panel 4 is formed into a flat plate shape so as to close the bottom opening of the upper panel 1.

Reference numeral 5 designates a fan casing, which has a nozzle portion that faces the air outlet 2 of the upper panel 1 between the end 7 of the nose portion 6 and the end 9 of the scroll portion 8 whose center distance gradually increases from the nose portion 7. 10, and a bell-mouth-shaped suction portion 11 is provided on the upper surface so that the entire end surface 12 of the scroll end 9 from the nose end 7 on the lower surface is brought into close contact with the lower panel 4.

Reference numeral 13 designates a plurality of wind direction plates arranged in parallel, which are rotatably supported on the upper and lower surfaces of the nozzle section 10.

A fan motor 14 is fixed to the upper surface of the upper panel 1 and facing the suction section 11 of the fan casing 5, and a centrifugal fan 16 is fixed to the drive shaft 15 of the fan motor.

17 is a heat exchanger, which has a heat exchanger tube 1 having a large number of needle-like fins.
8 is bent and formed in a U-shape so as to face each of the above-mentioned suction ports 3.

A heat exchanger chamber 19 is formed by the upper panel 1 and the fan casing 5, and forms a ventilation passage 20 extending from the suction port 3 of the upper panel 1 to the suction portion 11 of the fan casing 5.

Reference numeral 21 denotes a blower chamber, which is formed by the fan casing 5 and the lower panel 4, and forms an air passage 22 from the suction section 11 to the outlet 2 via the nozzle section 10 by means of the fan 16.

A drain tray 23 collects drain water generated by the heat exchanger 17, and is made of a foamed heat insulating material.

Above upper panel 1, lower panel 4 and fan casing 5
are integrally molded from various plastics, etc., and are connected by screw molds.

This invention is constructed as described above, and the upper panel and lower panel form the outer casing of the air conditioner body, and the fan casing divides the air conditioner into a blower room and a heat exchanger room. It is possible to form ventilation channels and air blowing channels on three sides of the outer casing circumferential side, and in one direction on the front. Therefore, the top and bottom heights of the outer casing can be flattened, and the wind In addition to making the flow smoother and more efficient, the upper panel, lower panel, and casing can be formed using the minimum necessary number of parts to reduce the number of parts, resulting in extremely high productivity. The benefits resulting from this invention are significant.
