1. An air conditioner indoor unit, comprising:
a base module, having a base part which is arranged with a fan motor;
a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; and
an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part, the air and water duct module has a bottom shell and an impeller which is rotationally mounted on the bottom shell; an impeller shaft of the impeller is suitable to be, by means of a quick release connecting structure, connected with and separated from an output shaft of the fan motor through a position movement between the impeller shaft and the output shaft, the quick release connecting structure comprises a clamping groove formed in the impeller shaft of the impeller and a clamping claw arranged on the output shaft of the fan motor and mating with the clamping groove,
at the working position of the fan motor, the clamping claw is arranged in the clamping groove and the output shaft rotates to drive the impeller shaft to rotate, the clamping claw is a helical clamping claw, and the clamping groove is a helical clamping groove, so that the output shaft rotate at the working position of the fan motor to make the helical clamping claw and the helical clamping groove get close to each other under the action of helical surfaces of the helical clamping groove and the helical clamping claw,
at the quick release position of the fan motor, when the fan motor is disassembled after the fan motor is unlocked, the clamping claw is separated from the clamping groove.
