Abstract

the object of invention is to provide an indoor unit of an air conditioner capable of increasing the degree of freedom of the layout of an auxiliary pipe. It comprises a cross flow fan 71, an indoor heat exchanger 50, the auxiliary pipe 51, and an indoor fan motor 72. The cross flow fan 71 is formed in a cylindrical shape. The indoor heat exchanger 50 is disposed to be opposed to the circular surface of the cross flow fan 71. The auxiliary pipe 51 extends from the side face of the indoor heat exchanger 50 to the outside. The indoor fan motor 72 is disposed parallel with the cross flow fan 71 in the rotating axis direction thereof and rotatingly driving the cross flow fan 71. Then the auxiliary pipe 51 extends to a position beyond the indoor fan motor 72 in the rotating axis direction.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner. Background technique [0002] The indoor unit of the air conditioner is equipped with a blower fan, a motor, and a heat exchanger, and the air is sent to the room through the heat exchanger. The motor is used to rotationally drive the blower fan, and in most cases the blower fan and the motor are arranged side by side in the direction of the rotation axis of the blower fan. [0003] In addition, some indoor units of air conditioners are equipped with a first drain pan, a second drain pan, and a communication path for receiving condensed water dripping from the front and rear ends of the heat exchanger. The communication path is a path for connecting the first drain pan and the second drain pan. Due to the provision of such a communication passage, the condensed water received by the first drain pan and the second drain pan can be collected in any one of the drain pans or the commu...
