[0032] The invention provides an air-conditioner indoor unit.

[0033] In the embodiment of the present invention, Figure 1 and Figure 4 As shown, the air conditioner indoor unit includes a shell 10 and an electrostatic dust removal module 20. The shell 10 has an air inlet 11 on the top, and the electrostatic dust removal module 20 is installed at the air inlet 11. The upper end of the shell 10 is provided with a pull-out opening 12 for disassembling and assembling the electrostatic dust removal module 20.

[0034] In this embodiment, the electrostatic dust removal module 20 is arranged at the air inlet 11 at the top of the indoor unit of the air conditioner, and the particle pollutants in the air entering the housing 10 are removed and collected by using the principle of electrostatic dust removal to ensure the cleanliness of the air entering the air conditioner. It should be noted that the air inlet 11 has a certain accommodation space, and installing the electrostatic dust removal module 20 at the air inlet 11 can also be understood as installing the electrostatic dust removal module 20 in the housing 10 and adjacent to the air inlet 11. The pull-out opening 12 is used for the electrostatic dust removal module 20 to be disassembled and assembled. For example, the installer can push the electrostatic dust removal module 20 into the housing 10 through the pull-out opening 12, or pull the electrostatic dust removal module 20 out of the housing 10. It can be understood that the pull-out opening 12 is connected to the air inlet 11, and the pull-out opening 12 can preferably penetrate the top of the housing 10 upward to prevent obstacles to the disassembly and assembly of the electrostatic dust removal module 20, which is more convenient for the disassembly and assembly of the electrostatic dust removal module 20.

[0035] The air-conditioning indoor unit of the present invention has a pull-out opening 12 at the upper end of the outer shell 10 for disassembling and assembling the electrostatic dust removal module 20, so that the electrostatic dust removal module 20 can be installed at the air outlet of the outer shell 10 or disassembled from the air inlet 11 of the outer shell 10 through the pull-out opening 12, which greatly facilitates the disassembly and assembly between the electrostatic dust removal module 20 and the outer shell 10 of the air-conditioning indoor unit and provides convenience for the inspection or replacement of the air-conditioning indoor unit.

[0036] Furthermore, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the housing 10 is provided with a rotatable limit knob 13 for positioning the electrostatic dust removal module 20 at the air inlet 11 .

[0037] In this embodiment, the limit knob 13 is arranged at a position adjacent to the drawer opening 12, and can be rotated to be opposite to the drawer opening 12 to abut against the front side of the electrostatic precipitator module 20, so as to fix the electrostatic precipitator module 20 at the air inlet 11. Correspondingly, the limit knob 13 can also be rotated to not be opposite to the drawer opening 12, so as to facilitate the removal of the electrostatic precipitator module 20. By installing the limit knob 13 on the housing 10, the installation of the electrostatic precipitator module 20 is more stable.

[0038] Furthermore, if Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Fig.10 As shown, the electrostatic dust removal module 20 is provided with a protruding limiting rib 21 , and the limiting knob 13 is provided with a sliding groove 131 that can slidably cooperate with the limiting rib 21 .

[0039] In this embodiment, the limiting rib 21 is used to cooperate with the limiting knob 13 to make the contact between the limiting knob 13 and the electrostatic dust removal module 20 more stable. The limiting rib 21 can preferably be arranged in an arc shape and extend along the rotation direction of the limiting knob 13, and the slide groove 131 can also preferably be arranged in an arc shape extending along the rotation direction of the limiting knob 13, so that the sliding cooperation between the limiting rib 21 and the slide groove 131 is smoother when the limiting knob 13 rotates. It can be understood that the rotation of the limiting knob 13 should be under the condition of applying a certain external force, and will not rotate under the action of its own gravity.

[0040] Furthermore, if Figure 6 As shown, the electrostatic dust removal module 20 is provided with a reinforcing rib 22 connected to the limiting rib 21. In this embodiment, the reinforcing rib 22 may preferably be multiple, and its shape and size will not interfere with the sliding fit between the limiting rib 21 and the limiting knob 13. The reinforcing rib 22 is used to enhance the structural strength of the limiting rib 21 to prevent the limiting rib 21 from being damaged when the limiting rib 21 is subjected to improper force, thereby enhancing the stability of the limiting rib 21.

[0041] Furthermore, if Figure 4 , Figure 7 and Fig. 9 As shown, a positioning boss 23 is convexly provided on the rear side of the electrostatic dust removal module 20 , and a positioning hole 14 adapted to the positioning boss 23 is opened in the housing 10 .

[0042] In this embodiment, the positioning hole 14 is provided on the inner wall of the housing 10 at a position abutting against the electrostatic dust removal module 20. Both the positioning hole 14 and the positioning boss 23 can be multiple and spaced along the length direction of the housing 10 or the electrostatic dust removal module 20 to enhance the stability of the connection between the electrostatic dust removal module 20 and the housing 10. The electrostatic dust removal module 20 is installed at the air inlet 11, and the positioning boss 23 is plugged into the positioning hole 14, which, on the one hand, realizes the positioning connection between the electrostatic dust removal module 20 and the housing 10, and on the other hand, enhances the stability of the installation between the electrostatic dust removal module 20 and the housing 10.

[0043] Furthermore, if Figure 1 , Figure 4 and Figure 8 As shown, the air conditioner indoor unit also includes an upper panel 30 that is detachably covered on the drawer opening 12. In this embodiment, the upper panel 30 is used to cover the drawer opening 12, that is, to cover the electrostatic dust removal module 20. In practical applications, the air conditioner indoor unit should also include a lower panel that covers other parts of the housing 10. It can be understood that since the upper panel 30 is only covered on the drawer opening 12, when disassembling the electrostatic dust removal module 20, it is only necessary to remove the upper panel 30 without removing other panels, making the disassembly and assembly of the electrostatic dust removal module 20 simpler and more convenient.

[0044] Furthermore, if Figure 8 and Fig.10 As shown, the front side of the electrostatic dust removal module 20 is provided with a snap hole 24, and the upper panel 30 is provided with a snap buckle 31 adapted to the snap hole 24. In this embodiment, the snap buckle 31 and the snap hole 24 are detachably engaged, and the upper panel 30 can be conveniently installed at the drawer opening 12 by engaging the snap hole 24 with the snap buckle 31. In practical applications, the snap buckles 31 can preferably be multiple and arranged in reverse intervals along the length of the upper panel 30, and the snap holes 24 are correspondingly multiple and arranged at intervals along the length direction of the electrostatic dust removal module 20, so that the connection between the upper panel 30 and the electrostatic dust removal module 20 is more stable.

[0045] Furthermore, if Fig. 9 and Fig.10 As shown, the upper end of the electrostatic precipitator module 20 extends forward to form a flange 25, and the clamping hole 24 is opened on the flange 25. In this embodiment, the flange 25 can be hollow to make it more convenient to open the clamping hole 24. By arranging the flange 25 at the upper end of the front side of the electrostatic precipitator module 20 and then opening the clamping hole 24 on the flange 25, it is possible to avoid the internal structure of the electrostatic precipitator module 20 interfering with the connection between the clamping hole 24 and the buckle 31.

[0046] Furthermore, if Figure 3 and Figure 8 As shown, the housing 10 is provided with a protruding clamping platform 15 , a clamping slot 151 is provided on the clamping platform 15 , and the upper panel 30 is provided with a clamping hook 32 adapted to the clamping slot 151 .

[0047] In this embodiment, the hook portion of the hook 32 is inserted into the slot 151 and the hook surface is overlapped on the hook platform 15 with the hook surface facing downward, so that the hook platform 15 can support the upper panel 30 through the hook 32, thereby realizing the connection between the upper panel 30 and the housing 10. Combining the above-mentioned embodiments of the buckle 31 and the clamping hole 24, the upper panel 30 is connected to both the housing 10 and the electrostatic dust removal module 20, thereby enhancing the stability of the installation of the upper panel 30.

[0048] The present invention also proposes an air conditioner, which includes an air conditioner indoor unit. The specific structure of the air conditioner indoor unit refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
