In addition, the degree of fit between the external filter and the panel body is difficult to grasp, resulting in the filter frame being easy to fall off or difficult to remove.

[0055] The present invention creatively provides an air-conditioning indoor unit, comprising a panel body, a filter rack and a connecting device, wherein an air inlet is formed on the top of the panel body; the filter rack is arranged at the air inlet and is formed with a first limiting structure; the connecting device comprises a slider formed with a second limiting structure, the slider can be controlled to slide, and when the slider is in the first working position, the first limiting structure and the second limiting structure are combined, and the filter rack is locked on the panel body; when the slider is in the second working position, the first limiting structure and the second limiting structure are separated, the filter rack is loosened and can be removed from the panel body; the structure is simple, and the disassembly and assembly process of the filter rack is optimized, the locking of the filter rack is reliable, the disassembly is easy and convenient, the filter rack does not shake, and the dust on it is not easy to fall off; it does not affect the overall appearance of the air-conditioning indoor unit; it solves the problem that the existing filter rack is difficult to disassemble and assemble and the dust on it is easy to fall off; it avoids the dust on the filter falling into the air conditioner and the need for frequent cleaning of various components in the air conditioner.

[0056] Example 1

[0057] like Figure 1 , Figure 2a and Figure 2b As shown, this embodiment provides an air conditioner indoor unit, including:

[0058] A panel body 11, with an air inlet 12 formed on the top of the panel body 11;

[0061] The slider can be controlled to slide. When the slider is in the first working position, the first limiting structure 221 and the second limiting structure 33 are combined, and the filter rack 2 is locked on the panel body 11; when the slider is in the second working position, the first limiting structure 221 and the second limiting structure 33 are separated, and the filter rack 2 is released and can be removed from the panel body 11; specifically, the first limiting structure 221 is a limiting groove, and the second limiting structure 33 is a limiting member; the slider slides relative to the panel body 11, and the limiting member is clamped in the limiting groove, so that the slider locks the filter rack 2, and the limiting member is disengaged from the limiting groove, so that the slider releases the filter rack 2.

[0062] To sum up, the connecting device 3 has a simple structure and optimizes the disassembly and assembly process of the filter rack 2. The locking of the filter rack 2 is reliable, and the disassembly and assembly is easy, convenient and quick, which saves time and effort and does not affect the overall appearance of the air-conditioning indoor unit 1. The filter rack 2 does not shake during disassembly, and the dust on it is not easy to fall off. The problem that the disassembly and assembly process of the filter rack 2 is complicated and the connection of the filter rack 2 is unreliable is solved, and the problem that the existing built-in filter rack is difficult to disassemble and assemble and the dust on it is easy to fall off is solved. The problem that the degree of coordination between the existing external filter rack and the panel body is difficult to grasp, which makes the external filter rack easy to fall off or difficult to disassemble is solved.

[0064] When the operating member is controlled to move, the screw rod 34 drives the slider to slide relative to the panel body 11 through the action of the transmission mechanism, and then the slider locks or releases the filter rack 2; simply controlling the movement of the operating member can achieve locking or loosening of the filter rack 2, the process is simple, time-saving and labor-saving, the filter 4 is reliably connected when it is fixed, and the filter 4 does not shake when it is loosened, and the dust on it is not easy to fall into the air conditioner.

[0066] When the screw rod 34 rotates forward, the first slider 31 and the second slider 32 move away from each other, the second limiting structure 33 of the first slider 31 is combined with a first limiting structure 221 of the filter rack 2, and the second limiting structure 33 of the second slider 32 is combined with another first limiting structure 221 of the filter rack 2, so that the filter rack 2 is locked, and the locking is firm and reliable;

[0067] When the screw rod 34 rotates in the opposite direction, the first slider 31 and the second slider 32 approach each other, the second limiting structure 33 of the first slider 31 is separated from a first limiting structure 221 of the filter frame 2, and the second limiting structure 33 of the second slider 32 is separated from another first limiting structure 221 of the filter frame 2, so that the filter frame 2 is loosened. At this time, the filter frame 2 can be disassembled along the thickness direction of the filter frame 2 without shaking, and the dust on it does not fall off; it can ensure that the filter screen 4 is not easy to fall off, and can also ensure that the filter screen 4 is easy to disassemble, which solves the problem that the degree of cooperation between the existing external filter frame 2 and the panel body 11 is difficult to grasp, resulting in the filter frame 2 being easy to fall off or difficult to disassemble; it solves the problem that the existing filter frame 2 has a complicated disassembly and assembly process and unreliable connection of the filter frame 2.
