Description

[Detailed Description of the Invention] This invention relates to an improved structure of an air conditioner that forcibly cools the inside of a machine room.

In the outdoor unit of a separate air conditioner, which generally has a partition plate that separates the blower room that houses the heat exchanger and blower from the machine room that houses the compressor and electrical components, the compressor is located in the machine room. Since the temperature rises due to heat dissipation from electrical components, a communication port is provided in the partition plate and the high temperature air inside the machine room is sucked out by the suction action of a blower.

However, in the conventional structure, a communication port was simply bored in the partition plate, or an elbow was attached to the communication port to further increase the suction effect, and the tip of the opening faced the suction side of the blower. The former structure does not provide a sufficient suction effect, and the latter structure has drawbacks such as the fact that the elbow body largely protrudes into the suction air passage of the blower, creating resistance to the suction air.

In view of these points, the purpose of the present invention is to provide an air conditioner which has a very high induced suction effect and which has a small pressure loss of the sucked air. In order to achieve this objective, the present invention involves tilting the partition plate that separates the ventilation room and the machine room toward the fan, providing a communication port in this slope for introducing air from the machine room into the ventilation room, and An airflow guiding device is provided on the side wall of the ventilation chamber of the air blower chamber, surrounding the communication port and drawing air from the communication port to the blower.

An embodiment of the present invention will be described below based on the drawings. 1 is a ventilation chamber 4 housing a plate-fin type heat exchanger 2 and an axial flow type blower 3; and a machine compartment 7 housing an elliptical compressor 5 and electrical components 6. This partition plate is formed into a substantially L-shape so as to be inclined toward the blower 3, and the inclined outer wall 8, which is the side wall surface of the blower chamber on one side of this slope, is separated from the blower 3. The other inclined outer wall 9 is also used as an air suction guide surface for the blower 3, and the other sloped outer wall 9 is used as an air discharge guide surface for the blower 3, respectively.

Reference numeral 10 denotes a communication port provided in the inclined part for introducing air from the machine room 7 into the ventilation chamber 4. The sloped outer wall 8, which is the side wall surface of the ventilation chamber, has a communication port surrounding the communication port 10 and air from the communication port. A box-shaped airflow guiding device 12 for drawing air to the blower 3 and a waterproofing device 13 for leading out are welded and fixed to the inclined inner wall 11, respectively.

In addition, 14 is an outside air introduction port bored above the front panel 15 of the machine room 7, 16 is an introduction waterproof device that covers the entrance, 17 is an outside air intake port, and 18 is an exhaust port.

Therefore, when outside air is drawn into the blower 3 from the inlet 17 via the heat exchanger 2, the attracting effect of the high-speed outside air flow flowing particularly along one outer wall 8 inclined toward the nozzle 19 of this blower and the blower. 3, the high-temperature air in the machine room 7 is quickly led out from the communication port 10 through the airflow guide 12 to the ventilation chamber 4 side, and is then diffused along the other inclined outer wall 9. Since it is quickly discharged, the heat radiated from the electrical components 6 stored above the machine room 7 and the heat radiated from the compressor 5 stagnant above is reliably led out, and the inside of the machine room 7 is filled with outside air from the inlet 14. Always maintained at a constant temperature.

Moreover, the elliptical compressor 5 is disposed along the inclined inner walls 11, 20 of the partition plate 1, and the heat from the compressor 5, which has a large amount of heat, is dissipated from the inner walls 11, 20.
By gathering the compressor 5 nearby, heat can be quickly drawn out from the communication port 10 and accumulated in the machine room 7 can be minimized, and since the compressor 5 can be stored compactly in the machine room 7, the unit This can greatly contribute to the miniaturization of 21.

Further, the waterproof devices 13 and 16 not only prevent rainwater from entering the machine room 7, but also act as guide devices that concentrate the flow of outside air to the electrical components 6 that particularly require cooling.

As described above, the present invention involves tilting the partition plate that partitions the ventilation room and the machine room toward the fan, providing a communication port in this slope for introducing air from the machine room into the ventilation room, and providing the ventilation in the slope. An air flow guiding device is provided on the chamber side wall surface to surround the communication port and draw the air from the communication port to the blower, so that the air is smoothly drawn into the blower along the slanted side wall surface of the blower chamber of the partition plate. The air inside the machine room is sucked into the blower through the communication port by the attraction effect that occurs when the high-speed outside airflow passes by the airflow guide. It is possible to sufficiently dissipate heat from the parts and maintain the machine room at a steady temperature.

Furthermore, by arranging the compressor along the inclined inner wall of the partition plate, the heat radiated from the compressor, which has a particularly large amount of heat, can be quickly discharged, and the unit can be made compact.
