Particularly, a plurality of blower fans are arranged in a row, and a front frame and a suction grill are separated into a plurality of air conditioners. It relates to an indoor unit of a multi-part split type air conditioner.

Generally, air conditioners are classified into a window type and a separate type or a split type.

The one-piece type and the separate type are functionally the same, but the one-piece type integrates the function of cooling heat dissipation, and is directly installed by drilling a hole in a wall of a house or by hanging a device on a window. And a compression device to connect the two devices separated from each other by a refrigerant pipe.

The separation type of the air conditioner as described above is largely composed of an indoor unit performing a cooling function, an outdoor unit performing a heat dissipation and compression function, and a refrigerant pipe connecting the indoor unit and the outdoor unit to each other.

1 is an exploded perspective view illustrating an internal structure of an indoor unit of a separate air conditioner according to the prior art, and referring to this, the indoor unit of the conventional separate air conditioner includes a chassis 20 fixed to a wall; It is coupled to the front surface of the chassis 20 to form a receiving space of the heat exchanger 49, the blowing fan 40 and the motor 42 together with the chassis 20, the inlet 12 is formed on the upper surface, A front frame 10 having a discharge port 14 formed on the lower surface of the front surface; It is configured to include a suction grill 30 rotatably coupled to the front of the front frame 10, the suction port 32 is formed.

One blower fan 40 is positioned in the horizontal direction in front of the chassis 20, and the blower fan 40 is rotatably supported by a support part 24 protruding perpendicularly to the front of the chassis 20. It is supported, and the heat exchanger 49 is bent in the front and the upper side of the blower fan 40, the lower side of the heat exchanger 49 so as to collect the condensate flowing from the heat exchanger (49) A condensate receiver 44 is formed at an upper portion, and a louver 45a for adjusting the left and right wind directions of the air discharged to the discharge port 14 and a vane for adjusting the up and down wind direction of the air discharged to the discharge port 14. The discharge grill 45 on which the 46b is installed is located.

The front frame 10 includes a plurality of filters for filtering bulky foreign matter from the air sucked into the air conditioner through the suction port 32 of the suction grill 30 and the suction port 12 of the front frame 10. An air filter 36 and a plurality of dust collectors 38 that ionize and remove dust in the air passing through the air filter 36 are mounted.

The chassis 20 is formed with a flow path portion 22 forming a flow path of air flowing by the blowing fan 40, the motor for driving the blowing fan 40 on one side of the blowing fan 40 42 is connected, and the control unit 46 is installed on the front side of the motor 42 is installed various electric components (not shown) for the operation of the air conditioner.

In the conventional air conditioner configured as described above, the indoor air sucked through the suction ports 12 and 32 is cooled through heat exchange with the refrigerant while passing through the heat exchanger 49, and the air thus cooled is a blower fan. After passing through the 40, it is guided to the flow path part 22 and discharged to the room through the discharge port 14.
