Particularly, indoor heat exchanger 2 and indoor fan 3 can be located the top of casing 1, and wherein indoor fan 3 can drive the circulation of the air flow in the heat transfer wind channel in order to realize the air, and indoor heat exchanger 2 can carry out the heat transfer with the air in the heat transfer wind channel. The indoor fan 3 operates to generate negative pressure so as to suck indoor air from the first air inlet 10b into the heat exchange air duct, and the air flows out from the first air outlet 10a after exchanging heat with the indoor heat exchanger 2 in the heat exchange air duct, so as to adjust the indoor temperature.

The air treatment device 4 is placed below the cabinet 1 to reduce the width of the indoor stand air-conditioning unit 100 in the front-rear direction, thereby saving the occupied space of the indoor stand air-conditioning unit 100. The air treatment device 4 comprises a shell 41, a guide fan 42 and a purification module 44, wherein an indoor air inlet 41a, a fresh air inlet 41b and an air outlet 41c are arranged on the shell 41, and an air treatment air duct 41d isolated from the heat exchange air duct is arranged in the shell 41, so that the influence of the air treatment device 4 on the heat exchange efficiency of the indoor unit 100 of the vertical air conditioner is avoided, the refrigeration/heating efficiency of the indoor unit 100 of the vertical air conditioner is ensured, meanwhile, the air treatment device 4 can be installed on the casing 1 as an independent component and can also be detached from the casing 1, and the air treatment device 4 is convenient to disassemble and assemble. The guide fan 42 and the purification module 44 are disposed in the casing 41, the indoor air inlet 41a and the fresh air inlet 41b are disposed on the rear wall 412 of the casing 41, a portion of the casing 41 extends rearward beyond the cabinet 1, a drawing opening 414a is disposed at a top portion of the casing 41 extending beyond the cabinet 1, the purification module 44 is detachably disposed in the casing 41 through the drawing opening 414a, and the purification module 44 is disposed at a front side of the indoor air inlet 41a and the fresh air inlet 41b to cover the indoor air inlet 41a and the fresh air inlet 41 b.

Specifically, the guiding fan 42 operates to generate a negative pressure, indoor air can flow into the casing 41 from the indoor air inlet 41a and outdoor air can flow into the fresh air inlet 41b and pass through the purifying module 44, when air (including indoor air and outdoor air) passes through the purifying module 44, dust particles in the air can be attached to the purifying module 44, so that the air is purified, and the purified air returns to the indoor space from the air outlet 41c, so that the body health of a user can be guaranteed, and the use comfort of the user is improved.

As shown in fig. 1 to 6, the housing 41 has an extension portion 414 extending rearward, and a rear end of the extension portion 414 extends rearward beyond the cabinet 1, wherein the extension portion 414 may extend horizontally rearward, but is not limited thereto. Therefore, by arranging the air treatment device 4 and the casing 1 up and down and extending a part of the casing 41 backward beyond the casing 1, the space in the casing 41 is made larger on the premise of ensuring that the width of the indoor unit 100 of the floor air conditioner in the front-rear direction is smaller, which facilitates the arrangement of the guide fan 42 and the purification module 44.

The drawing opening 414a penetrates the extending portion 414 along the up-down direction, so that the purification module 44 can be connected to the housing 41 through the drawing opening 414a from the top down to realize the installation of the purification module 44, and the purification module 44 can also be separated from the housing 41 through the drawing opening 414a from the bottom up to realize the detachment of the purification module 44. Wherein, the top of the purification module 44 may be provided with a drawing part 441a, so as to rapidly complete the disassembly and assembly of the purification module 44. Therefore, the drawing opening 414a is arranged on the top of the housing 41, so that the purification module 44 can be quickly disassembled and assembled, and the disassembly and assembly efficiency can be improved.

That is, when the indoor unit 100 of the floor air conditioner operates, the switch module may only open the indoor air inlet 41a and the fresh air inlet 41b remains closed, at this time, the indoor air may flow into the air treatment duct 41d, and the outdoor air may not flow into the air treatment duct 41 d; or the switch module can only open the fresh air inlet 41b and the indoor air inlet 41a to keep a closed state, at this time, the outdoor air can flow into the air processing duct 41d, and the indoor air cannot flow into the processing duct; or the switch module opens the indoor air inlet 41a and the fresh air inlet 41b at the same time, and at this time, both the outdoor air and the indoor air can flow into the air processing duct 41d, and of course, the switch module can also close the indoor air inlet 41a and the fresh air inlet 41b at the same time. Therefore, the control mode of the switch module can be controlled according to actual conditions, and the states of the indoor air inlet 41a and the fresh air inlet 41b are further controlled.

As shown in fig. 6 to 12, the indoor unit 100 of the floor air conditioner further includes a purification net 5, and the purification net 5 is detachably disposed at the first air inlet 10 b. From this, indoor air flows into casing 1 from first air intake 10b in, earlier through purifying net 5 in order to purify indoor air, and the air after the purification flows out from first air outlet 10a after carrying out the heat transfer with indoor heat exchanger 2 in the heat transfer wind channel to when adjusting indoor temperature, further realized the purification of air. It will be appreciated that the purification web 5 may be selected as a filter web, such as a hepa filter web, to ensure the purification effect of the purification web 5. But is not limited thereto.
