The present invention relates to an air conditioner, and in more detail, an air guide unit is positioned between an inlet port located at the rear side and an outlet port located at the front side, such that the air of the air conditioner indoor unit can be easily discharged to the front side. It is about a guide structure.

In general, the air conditioner performs a refrigeration cycle of the refrigerant circulating therein compression, condensation, expansion and evaporation. In particular, in the case of an air conditioner, the refrigerant is compressed to high temperature and high pressure, and then heat is released to the outside from the condenser, and the temperature and pressure drop considerably while passing through the expansion valve. The low temperature and low pressure refrigerant passes through the evaporator, absorbs heat, and then enters the condenser again.

Here, the compression process, the condensation process and the expansion process are performed in the outdoor unit of the air conditioner, and the evaporation process is performed by the blower fan and the heat exchanger of the indoor unit.

In addition, the air conditioner is largely divided into a window type air conditioner in which a refrigeration cycle device is mounted in one body and installed in a window, and a separate air conditioner installed in a city and an outdoor unit by separating an indoor unit and an outdoor unit.

In addition, in the case of the separate type air conditioner, it is classified into a wall-mounted type, an upper tooth type, a ceiling-hanger type, and a ceiling-embedded type according to the installation method.

In addition, the indoor unit of the structure that can be used as a wall-mounted or upper teeth type, and can also be used as a ceiling-mounted type according to the needs of the user is called a convertible indoor unit.

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, 2, and 3, the conventional air conditioner indoor unit 10 includes a front panel 20 including a display unit 21 on which a signal from a remote controller is received to indicate whether the air conditioner is operated, and the front panel. In contact with the indoor air sucked from the upper side of the panel 20, the filter 30 for filtering foreign matter contained in the intake air, and the filter 30 and the front panel 20 is seated to form a front portion A heat exchanger 60 which lowers the temperature of the intake air by contacting the front frame 35, the purified air passing through the front frame 35, and formed at a rear side of the heat exchanger 60; Blowing fan 50 for sucking the low-temperature indoor air passed through the (60), orifice 70 for guiding the flow of air in the low-temperature state sucked by the blowing fan 50, and the orifice 70 Bay with discharge part for discharging air guided by (40) is 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 Is deprived of heat while in 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.

 Therefore, the flow path of the indoor air from the inlet to the outlet is not in a straight line but in a "U" shape or a "L" shape. 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.

In addition, when the suction port 25 and the discharge ports 31 and 33 are formed on the same plane of the front surface of the indoor unit, the area of the suction port 25 is limited, so that the indoor air to be sucked is exchanged with the heat exchanger 60. A problem arises in that the area of contact with) becomes small.

In addition, when the suction port 25 is located at the front surface, when the front panel 20 is opened, there is a problem that the heat exchanger 60 is exposed to the outside so that the appearance is not good.

In addition, when the suction port 25 is located on the front surface, the low-temperature air discharged to the front surface is again sucked through the suction port 25, the temperature of the air sucked through the suction port 25 than the actual temperature of the indoor space A problem arises that becomes low. As a result, the air conditioner does not obtain accurate temperature data, resulting in a problem that the efficiency of the indoor unit 10 is lowered.

 The present invention has been proposed to solve the above problems, and an object of the present invention is to provide an air conditioner indoor unit which allows the indoor air to be easily moved from the inlet to the outlet by installing an air guide between the rear inlet and the front outlet. do.

In addition, an object of the present invention is to provide an indoor unit of an air conditioner, by which indoor air is easily guided from the inlet to the outlet by the air guide, thereby minimizing the loss caused by the flow resistance.

In addition, an object of the present invention is to provide an indoor unit of an air conditioner in which a suction port is formed on a rear surface of an indoor unit, so that the heat exchanger is not exposed to the outside during operation and stop of the indoor unit.
