It can be understood that the first pipe section 221 extends along the height direction of the casing 100 and is disposed in the avoiding portion 331, so that the arrangement direction of the first pipe section 221 can correspond to the wall, the first pipe section 221 does not exceed the casing 100 due to unreasonable arrangement, and the phenomenon that the refrigerant pipe 220 is pushed against the wall when the indoor unit of the air conditioner is mounted on the wall is avoided; meanwhile, the first pipe section 221 extends along the height direction of the casing 100, so that the arrangement direction of the first pipe section 221 is regular, and the improvement of the space utilization rate inside the indoor unit of the air conditioner is facilitated.

Further, the first pipe section 221 is disposed in the avoiding portion 331, the second pipe section 222 is connected to one end of the first pipe section 221, the second pipe section 222 extends along the length direction of the casing 100 and is located below the fresh air pipe assembly, specifically, the second pipe section 222 is located below the fresh air pipe 320, so that the fresh air pipe 320 and the second pipe section 222 do not interfere with each other, the refrigerant pipe 220 and the second pipe section 222 can be smoothly arranged in the casing 100 and extend out of the casing 100 from the same side, thereby ensuring fresh air intake of the fresh air pipe 320 and the stability of the refrigerant pipe 220 in refrigerant transmission, and further facilitating improvement of the working stability of the indoor unit of the air conditioner. Meanwhile, the second pipe section 222 extends along the length direction of the casing 100 and is located below the fresh air pipe assembly, so that the second pipe section 222 and the fresh air pipe assembly can be smoothly arranged in the casing, the situation that the second pipe section and the fresh air pipe assembly are staggered and stacked to exceed the casing 100 is avoided, and the technical problem that the installation gap is too large or the installation cannot be carried out when the indoor unit of the air conditioner is installed on the wall is avoided.

In one embodiment, the pipe fitting 330 is made of a hard material. So set up for dodging position 331 on the coupling 330 is difficult to warp to guaranteed to dodge position 331 and can dodge refrigerant pipe 220, so that refrigerant pipe 220 and fresh air pipe 320 can be smooth and easy arranging in casing 100, thereby improved the stability of machine work in the air conditioning.

Referring to fig. 1 and fig. 6, in an embodiment, the casing 100 includes a chassis 120, and a pipe running groove 121 is disposed on a back surface of the chassis 120, and the pipe running groove 121 is configured to accommodate the fresh air pipe assembly and the second pipe segment 222. It can be understood that the duct slot 121 extends along the length direction of the casing 100, and the fresh air duct assembly and the second duct segment 222 are disposed in the duct slot 121. Therefore, the positions of the fresh air pipe assembly and the second pipe section 222 can be further limited by utilizing the pipe running groove 121, so that the refrigerant pipe 220 and the second pipe section 222 can be smoothly arranged in the casing 100, the working stability of the indoor unit of the air conditioner is improved, and the space utilization rate of the inside of the indoor unit of the air conditioner is also improved.

The present invention further provides an air conditioner, which includes the above air conditioner indoor unit, and the specific structure of the air conditioner indoor unit refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, the air conditioner at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
