Description

Indoor unit of separate air conditioner

The present invention relates to an indoor unit of a separate type air conditioner, and more particularly, to an indoor unit of a type type air conditioner that enables various types of discharge angles of air.

An air conditioner is a device for adjusting the temperature, humidity, airflow, and cleanliness of air sent to the room to create a comfortable indoor environment. The air conditioner is classified into an integrated type and a separate type according to the configuration of the unit.

An integrated air conditioner allows the components of the refrigeration cycle to be housed in a single case, absorbing latent heat from the compressed and condensed refrigerant as it passes through the capillary and allowing it to evaporate through the evaporator as it passes through the compressor and condenser. It is an air conditioner to perform the cooling operation.

The split type air conditioner usually divides the components that make up the refrigeration cycle into two parts, and the blower, the evaporator, and the air filter are indoors. It is an air conditioner installed so that cooling can be performed.

FIG. 6 is a perspective view of a conventional detachable air conditioner indoor unit, and FIG. 7 is a side cross-sectional view of the indoor unit of FIG. 6. As shown in these figures, the indoor unit of the separate type air conditioner has a rectangular parallelepiped casing 101 and a casing 101 in which a front air intake 103 and an upper air intake 105 are formed in the front and upper regions, respectively. The heat exchanger 102 is disposed adjacent to the internal air intake area of the heat exchanger 102 and heats the air introduced through the air intake holes 103 and 105 to pass through the heat exchanger, and blows the heat-exchanged air into the rear of the heat exchanger 102. It has a cross pan 104.

The lower region of the heat exchanger 102 is installed to stand side by side in the front air intake 103, the upper region is formed to be inclined upward toward the upper air intake 105. An air filtration device 107 is interposed between the heat exchanger 102 and the upper air suction port 105 so as to filter dust in the air introduced through the upper air suction port 105.

On the other hand, the air discharge port 111 opened along the longitudinal direction of the casing 101 is formed in the lower front region of the casing 101, and the edge of the air discharge port 111 is disposed along the longitudinal direction of the casing 101. The vertical adjustment member 113 is installed to be able to rotate up and down about the rotating shaft. In addition, a plurality of left and right adjustment members 115 are installed at the edge of the air discharge port 111 so as to be able to rotate left and right with respect to the casing 101 about a rotational shaft disposed horizontally in the longitudinal direction of the air discharge port 111. .

By such a configuration, when the cross fan 104 is driven, air is introduced into the casing 101 through the front air suction port 103 and the upper air suction port 105. The air introduced into the casing 101 is heat-exchanged while passing through the heat exchanger 102 to be provided indoors through the air discharge port 111 formed in the lower front region of the casing 101. At this time, the left and right regulating member 115 and the upper and lower regulating member 113 provided in the air discharge area are rotated around the rotating shaft, respectively, to adjust the wind direction of the air.

By the way, in the indoor unit of such a conventional type air conditioner, the air discharge port is formed in the lower front region of the casing in parallel with the rotation shaft of the cross pan, so that the treated air is discharged only to a predetermined region so that from the flow path of the air The spaced apart area has a problem that heat exchange and / or air treatment are not effective. Therefore, although the wind direction control means is provided in the air discharge port area in consideration of such a problem, there is a problem that is insufficient to effectively solve the problem of heat exchange and air treatment area due to the structure of the air discharge port.

Accordingly, it is an object of the present invention to provide an indoor unit of a separate type air conditioner that can select not only various discharge angles of treated air but also appropriately select an air treatment area.
