The present invention relates to an indoor unit of an air conditioner, and more particularly, to a base structure that forms the outer surface of the indoor unit and in which indoor air is sucked.

1 is a perspective view of a conventional air conditioner indoor unit sucked to the front surface and discharged to the front surface, FIG. 2 is an exploded perspective view of the indoor unit, and FIG. 3 is a perspective view showing a flow path of air passing through the indoor unit.

1 to 3, the conventional air conditioner indoor unit 10 includes a front panel 20 including a display unit 21 on which a signal of a remote controller is received and whether the air conditioner is operated, and the front panel 20. The front frame which contacts the indoor air sucked from the upper side of the filter, filters the foreign matter contained in the intake air, and the filter 30 and the front panel 20 are seated to form a front part. 35), a heat exchanger 60 for lowering the temperature of the intake air by contacting the purified air through the front frame 35, and formed at a rear side of the heat exchanger 60, the heat exchanger 60 Blower fan (50) for sucking the low-temperature indoor air, and the orifice (70) for guiding the flow of low-temperature air sucked by the blower fan (50), and guided by the orifice (70) The base 40 having a discharge portion for discharging compressed air Included.

In detail, a drain pan 80, which condenses on the outer wall of the heat exchanger 60 and collects moisture in the air, is included, and an upper portion 75 of the orifice 70 controls the driving of electrical components. It is seated.

In more detail, the upper inner surface of the base 40, the low-temperature air sucked into the blowing fan 50 through the orifice 70 is not discharged to the upper side, the air flows so as to discharge to the left and right sides of the indoor unit A flow guide 90 for guiding the seat is seated.

Hereinafter, the function and operation of the indoor unit 10 of the air conditioner will be described.

First, when an operation signal is received by a remote controller or a manual unit on the display unit 21 mounted on the front panel 20 of the indoor unit 10, the upper side of the front panel 20 is opened. In other words, the opened portion becomes the suction port 25.

In addition, when the motor (not shown) mounted inside the indoor unit 10 is operated, the blowing fan 50 is rotated, and the indoor air is sucked through the suction port 25.

The sucked indoor air is purified through the air filter 30 and then passed through the heat exchanger 60. Since the pressure and temperature of the refrigerant flowing inside the heat exchanger 60 are very low, the sucked indoor air The air is deprived of heat as it comes into contact with the heat exchanger 60. Thus, the temperature of the indoor air passing through the heat exchanger 60 drops.

The indoor air passing through the heat exchanger 60 is introduced into the blowing fan 50 through the orifice 70, and the air introduced into the blowing fan 50 is discharged back into the room through the discharge ports 31 and 33. do.

However, in the conventional air conditioner indoor unit as described above, the indoor air is sucked into the front and discharged to the front. In more detail, the indoor air is sucked into the front of the indoor unit is discharged to the front both sides and the lower side.

As a result, there is a problem in that the flow resistance of the air is increased compared to an indoor unit in which the flow path of the air is formed in a single line. And, there is a problem that the noise occurs in the indoor unit as the flow resistance of the air increases.

The present invention has been proposed to solve the above problems, by installing an air intake port on the back, so that the indoor air is sucked and discharged to form a straight line, the indoor unit of the air conditioner to minimize the loss due to the flow resistance The purpose is to provide.

In addition, an object of the present invention is to provide an indoor unit of an air conditioner such that the intake port is formed on the rear surface of the indoor unit, so that the heat exchanger is not exposed to the outside during the indoor unit operation and the positive instruction.

The base structure of the air conditioner indoor unit according to the present invention for achieving the object as described above is at least one suction port formed on the inclined surface, both sides and / or the upper and lower sides are inclined at a predetermined angle; It includes; filter insertion opening formed at the bottom of the inclined surface.

By the above configuration, the flow resistance is significantly reduced in the process of the indoor air is sucked and discharged, there is an effect of reducing the noise due to the flow.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the embodiments set forth below, and other embodiments included within the scope of other inventive inventions or the scope of the present invention by adding, changing, or deleting other elements are not limited to the embodiments.
