Description

[Detailed description of the invention] The present invention relates to an improvement of an air conditioner that has a heating function and is capable of blowing warm air upward or simultaneously upward and downward, and aims to improve air blowing efficiency. This is one of the purposes.

Conventionally, this type of air conditioner has a suction port provided on the front surface of the air conditioner main body a, as shown in FIG. e was configured to perform control such as opening during cooling and closing during heating.

However, with such a configuration, during heating, the air will not reach the lower air outlet d unless the upper air outlet C is completely closed, and the wind flow will change direction by 180 degrees. Therefore, the ventilation resistance is large, and the ventilation circuit becomes complicated, resulting in problems such as noise and a reduction in air volume.

The present invention eliminates the drawbacks found in the above-mentioned conventional air conditioners.

Hereinafter, Figures 1 to 1 of the accompanying drawings showing one embodiment of the present invention will be described.
This will be explained with reference to FIG.

In the figure, 1 is the main body of the air conditioner, and the front panel 1a
A suction port 2 is provided at the top, and blowout ports 3 and 4 are provided at the top and bottom ends, respectively.

Reference numeral 5 denotes a fan casing provided within the main body 1, which communicates with each of the air outlets 3.4, and houses a centrifugal fan 6 and a motor 7 therein.

Reference numeral 8 denotes a heat exchanger provided between the suction port 2 and the suction port of the fan casing 5, and a water tray 9 is provided below the heat exchanger.

Here, as shown in FIG. 2, the lower air outlet 4 communicates with the fan casing 5 at a tilted position due to the use of a centrifugal fan 6, and its shape changes as it approaches the opening end as shown in FIG. It is formed in an expanded shape.

10 is a partition plate provided vertically at the center of the opening of the lower air outlet 4 in communication with the fan casing 5, and is provided across the center of the expanded opening;
Air from the fan casing 5 is blown out over the entire lower outlet 4.

Reference numeral 11 denotes a damper that is rotatably provided on a part of the fan casing 5 and is rotatable around a shaft 11a, which distributes the air in the fan casing 5 to the upper outlet 3 and the lower outlet 4. is blocking communication with the lower air outlet 4 due to its own weight.

Reference numeral 12 denotes a scroll plate provided on the lower surface of the damper 11, which regulates the flow of air so that all the air flowing to the lower outlet 4 when the damper 11 is opened is directed downward.

Reference numeral 13 denotes an extendable and retractable operating device for opening and closing the damper 11, and is fixed to the main body 1 side so as to come into contact with the operating piece 11a of the damper 11.

Here, the actuating device 13 detects the high-pressure side pressure or indoor temperature (suction air temperature) of a well-known refrigeration cycle configured together with the heat exchanger 8, etc., and when the detected value reaches a set value. This opens the damper 11.

In the above configuration, when the high pressure side pressure increases or the indoor temperature decreases during heating operation, the actuating device 13 detects this and opens the damper 11.

Therefore, the hot air that was previously blown out only from the upper outlet 3 is now blown out also from the lower outlet 4, maintaining a good temperature distribution in the room.

At this time, since the passage for downward blowing does not become long as in the conventional case, the ventilation resistance is small and the ventilation ability is excellent.

Further, the air flowing to the lower outlet 4 is controlled by a damper 11
Since the air is guided in the same direction by the scroll plate 12 provided in the lower air outlet 4, the efficiency of air blowing to the lower air outlet 4 is excellent.

Further, since the lower outlet 4 is provided with a partition plate 10 at its center, the air is divided over the entire lower outlet 4 and is blown out from the entire lower outlet into the room while spreading.

Therefore, the indoor temperature distribution also becomes better.

As is clear from the above embodiments, the ventilation control structure of the air conditioner according to the present invention has a main body of the air conditioner equipped with a heat exchanger, a blower, a fan casing, etc., and the upper and lower parts of the fan casing are connected to each other. suction ports corresponding to the upper and lower air outlets and the heat exchanger are respectively provided; further, a damper is provided in the fan casing or the main body for controlling communication between the lower part of the fan casing and the lower air outlet; The lower outlet has a shape that widens toward the blowout direction, and when the lower blowout is used, the passage does not become long as in the conventional case, resulting in good ventilation efficiency. Therefore, the blown air is blown out while spreading radially, which has various advantages such as further improving the temperature distribution.
