[0052] Combination Figures 1 to 19As shown, an embodiment of the present disclosure provides an air-conditioning indoor unit, including a main unit 10, a sub-unit 20 and a door mechanism 30; the main unit 10 includes a shell 100, a sub-accommodating chamber 110 is provided in the shell 100, and an opening 130 that can expose the sub-accommodating chamber 110 is provided on the front panel 120 of the shell 100; the sub-unit 20 is arranged in the sub-accommodating chamber 110; the door mechanism 30 can be slidably arranged in the opening 130, and the door mechanism 30 includes a cover plate 310 and a bracket assembly 320, and the cover plate 310 is connected to the bracket assembly 320, wherein the bracket assembly 320 can move and switch between a first position and a second position along the vertical direction of the shell 100 to drive the cover plate 310 to switch between a shielding state and an avoidance state, the shielding state includes shielding the opening 130, and the avoidance state opens the opening 130.

[0053] Optionally, the housing 100 is provided with a main accommodating chamber and a sub-accommodating chamber 110 which are distributed up and down. A heat exchanger and a fan assembly are arranged in the main accommodating chamber, and a main air inlet and a main air outlet connected to the indoor environment are arranged on the housing 100. Under the action of the fan assembly, the indoor air flows into the main accommodating chamber through the main air inlet, and after heat exchange with the heat exchanger, under the action of the fan assembly, the air flows back to the room through the main air outlet, so as to adjust the temperature or humidity of the indoor environment.

[0054] The sub-accommodation chamber 110 is arranged below the main accommodation chamber, that is, located at the lower part of the housing 100. The sub-accommodation chamber 110 is provided with a sub-machine 20, and the sub-machine 20 moves into or out of the sub-accommodation chamber 110 through the opening of the housing 100. In order to prevent foreign matter such as dust or insects and ants from entering the sub-accommodation chamber 110, a door mechanism 30 is provided at the opening. Optionally, the sub-machine 20 includes one or more of a humidity adjustment module, a temperature adjustment module and a purification module. When the sub-machine 20 moves out of the sub-accommodation chamber 110, air supply at different distances, different positions and different directions can be achieved to purify the indoor environment, or adjust the humidity, or adjust the temperature, so as to improve the treatment effect on the indoor air.
