Referring to fig. 1 to 3, an indoor unit according to an embodiment of the present application includes: the air conditioner comprises a shell 100, wherein the shell 100 is formed by enclosing a plurality of side walls 110, and an air duct 120 is arranged in the shell 100; a barrier layer disposed on an interior side of at least one of the sidewalls 110.

The housing 100 is made of plastic by using a mold. When the indoor unit operates, air flows with different temperatures, namely hot air or cold air, are blown out to the indoor side along the air duct 120, and the shell 100 is affected by the hot air or the cold air, so that other plastic parts forming the shell 100 expand with heat and contract with cold to deform.

By providing the barrier layer on the side walls 110 that constitute the air duct 120. The barrier layer sets up at least one on the medial surface of lateral wall 110, the barrier layer is separated and is followed the air current that wind channel 120 blew out with lateral wall 110 has avoided lateral wall 110 and cold wind or hot-blast contact, and then reduce lateral wall 110 expend with heat and contract with cold phenomenon. The deformation of the side wall 110 or other plastic parts is reduced, so that the connection stability between the side wall 110 and other plastic parts is improved, the abnormal sound of the air conditioner is reduced, and the user experience is improved.

In some embodiments, the housing 100 is enclosed by 4 sidewalls 110, and the 4 sidewalls 110 enclose the air duct 120. The 4 side walls 110 are respectively an upper wall 111, a lower wall 112, a left wall 113 and a right wall 114, and the indoor unit has a simple and stable structure and high space utilization rate, and can reduce the indoor space occupied by the indoor unit.
