The utility model provides an air conditioner indoor unit and air conditioner, air conditioner includes: the shell is provided with air outlet and air intake on, the heat exchanger sets up in the shell, including first portion heat exchanger and second portion heat exchanger, and the one end interconnect of first portion heat exchanger and second portion heat exchanger, and interconnect's one end is the first angle setting of predetermineeing each other and all extends to the air intake near air outlet setting, the other end of first portion heat exchanger and second portion heat exchanger, baffle, its one end are installed and are served with second portion heat exchanger interconnect's no. 1 at the first portion heat exchanger, and its other end lies in and extends between first portion heat exchanger and the second portion heat exchanger and to the the direction of gravity slope of baffle. The usable baffle of this scheme blocks the comdenstion water, and the comdenstion water that is blocked can flow in to the water collector and by normal discharge along the baffle to can prevent that the comdenstion water from being blown out by the direct air outlet of following, and then can solve the problem that the air conditioner condensation blows water.
