Description

Apparatus for controlling wind direction of air -conditioner}

The present invention relates to a wind direction control device for an air conditioner, and more particularly, the horizontal blades are divided into upper and lower blade portions, and the individual blades can be driven by concentrating the air discharged from the air outlet, The present invention relates to an air conditioner for controlling air conditioners that can extend the reach and improve the cooling capability in long-range or wide-area cooling.

In general, an air conditioner that performs cooling or heating by using a temperature change of air, such as an air conditioner or a hot air fan, sucks air in a room and cools or heats it by a heat exchanger, and then cools or heats the cooled or heated air. By discharging back to the room, a predetermined function is performed.

An air conditioner, which is used to cool the room using a cooling cycle, liquefies the refrigerant compressed in the compressor in a condenser and then evaporates through an expansion valve or capillary tube. It is an air regulator that performs cooling by evaporation heat of refrigerant absorbed by evaporation in an evaporator.

The package air conditioner as described above is generally configured to be separated into an indoor unit in which an evaporator is built and an outdoor unit in which electrical components such as a condenser and a compressor are built in consideration of noise problems and installation conditions.

1 schematically shows an indoor unit of such a package air conditioner, which is provided with an evaporator (E) connected to an outdoor unit (not shown) above an interior of a cabinet (C), and circulates indoor air at a lower portion thereof. Sirocco fan (F) is installed and configured.

Accordingly, the air in the room is sucked into the inlet grill G1 of the cabinet C by the fan F and cooled while passing through the evaporator E, and then the outlet grill of the cabinet C is cooled. It is discharged back to the room through G2) to cool the room.

On the other hand, for uniform and comfortable cooling of the room, the discharged cold air should be evenly distributed all over the bar. The discharge grill G2 of the indoor unit is generally configured to control the wind direction of the discharged air.

Figure 2 shows a conventional wind direction control device for this.

As shown, the horizontal and vertical blades (2, 3) of the discharge grill (G2) are rotatably installed in a frame (frame: 1) installed in the air discharge hole (H) of the cabinet (C), respectively. Each of the horizontal and vertical blades 2 and 3 is connected to each other by vertical and horizontal links 4 and 5.

In addition, by horizontally and vertically driving either horizontal and vertical blades (2, 3) to the horizontal and vertical motors (6, 7), respectively, the horizontal and vertical blades (2, 3) are simultaneously inverted within a certain angle range. have.

However, the conventional wind direction control device as described above has a problem in that the discharge air is effective in near or medium-distance cooling, but in the case of long-distance cooling or wide area cooling, the cooling air does not reach the required reach distance, thereby reducing the cooling effect.

An object of the present invention, which was devised to solve the above problems, divides a plurality of horizontal blades into an upper blade portion and a lower blade portion, and controls them separately to concentrate the air discharged from the air discharge port, thereby reaching the distance of the discharged air. The present invention provides an air conditioner that can expand the air conditioner to improve the cooling ability at the time of remote cooling or wide area cooling.
