[0033] The present invention provides an air conditioner indoor unit.

[0034] Referring to Figure 1 , in the first embodiment of the present invention, the air conditioner indoor unit is specifically a wall-mounted air conditioner indoor unit. The air conditioner indoor unit includes a chassis 1, an air duct assembly (not labeled), a front frame 3, a grille assembly (not labeled), a first panel 5, and a second panel 6. Among them, the air duct assembly is detachably connected to the chassis 1; an installation opening (not labeled) and a disassembly opening 32 for the air duct assembly to be removed are formed on the front frame 3; the grille assembly includes a grille member 41 detachably installed in the installation opening and a filter screen (not labeled) provided on the grille member 41; the first panel 5 is used to open or cover the disassembly opening 32, and an air outlet 51 connected to the air duct of the air duct assembly is formed on the first panel 5; the second panel 6 cooperates with the first panel 5 to cover one surface of the front frame 3.

[0035] It should be noted here that in this embodiment, the front frame 3 includes an upper bracket 33, a lower frame 34, and two opposite side connectors 35 located between the upper bracket 33 and the lower frame 34. The installation opening is formed between the upper bracket 33 and the lower frame 34, the disassembly opening 32 is formed on the lower frame 34, and the grille member 41 is detachably installed on the upper bracket 33. When the air conditioner indoor unit is in use, air is cooled and then blown out after passing through the grille member 41, the filter screen, a heat exchanger (not labeled), the air duct assembly, and the air outlet 51 in sequence.

[0036] In this embodiment, on the one hand, since the first panel 5 can be opened relative to the front frame 3 to expose the disassembly opening 32, the air duct assembly detachably connected to the chassis 1 can be conveniently detached from the disassembly opening 32, thus providing great convenience for the in-depth cleaning of the air duct, heat exchanger and other related components. On the other hand, since the front frame 3 is provided with an installation opening, and the grille member 41 installed with the filter screen is detachably connected to the installation opening, the filter screen can also be conveniently detached for cleaning. The combined effect of these two aspects can improve the disassembly and assembly convenience of the air conditioner indoor unit, thus facilitating the comprehensive in-depth cleaning of the air conditioner indoor unit and helping to reduce the health hazards brought by the air conditioner indoor unit.

[0037] Referring to Figures 1 to 5 , in this embodiment, preferably, the first panel 5 is detachably snap-connected to the front frame 3. Specifically, the first panel 5 and the second panel 6 cooperate to cover the front side of the front frame 3, and the second panel 6 is located above the first panel 5; the left and right ends of the first panel 5 are detachably snap-connected to the front frame 3. Of course, it can also be the upper and lower ends or the four peripheral edges of the first panel 5 that are detachably snap-connected to the front frame 3. However, in this embodiment, the setting that the first panel 5 is detachably snap-connected to the front frame 3 at its left and right ends can make the structure simpler and avoid interference with the disassembly of the air duct assembly.

[0038] Further, referring to Figure 2 , Figures 4 to 5 , in this embodiment, a plurality of buckles 52 are convexly provided on the inner side surface of the first panel 5, and buckle holes 36 for the buckles 52 to be inserted into are provided on the front side surface of the front frame 3. In this way, the snap connection between the first panel 5 and the front frame 3 can be realized by inserting the buckles 52 into the corresponding buckle holes 36. When the first panel 5 needs to be detached, just let the buckles 52 disengage from the buckle holes 36. Specifically, a plurality of buckles 52 are provided and are respectively arranged on the inner side surfaces of the left and right ends of the first panel 5. The left and right side edges of the lower frame 34 extend inward to form convex plates 341, and the buckle holes 36 are formed on the convex plates 341, that is, the buckle holes 36 are arranged on the left and right sides of the disassembly opening 32 to avoid affecting the disassembly of the air duct assembly. However, this design is not limited to this. The buckles 52 can also be provided on the front side surface of the front frame 3. Correspondingly, the buckle holes 36 are provided on the inner side surface of the first panel 5. In addition, the structure snap-connected to the buckles 52 is not limited to the buckle holes 36, and can also be a snap connection seat or other structures.

[0039] Specifically, in order to make the structure simpler while ensuring the snap connection firmness, preferably two relatively spaced buckles 52 are respectively provided on the inner side surfaces of the left and right ends of the first panel 5. Among them, the free end of the buckle 52 is provided with a card convex portion 521 extending in the up and down direction, and the extending directions of the card convex portions 521 of the two buckles 52 on the same side are opposite. As Figure 5As shown in the figure, two buckles 52 on the same side are spaced apart in the vertical direction. Among them, the upper buckle 52 is disposed adjacent to the upper end of the first panel 5, and its locking convex portion 521 extends upward, while the locking convex portion 521 of the lower buckle 52 extends downward. Thus, when the buckle 52 is inserted into the buckle hole 36, the locking convex portion 521 abuts against the inner side surface of the edge of the buckle hole 36, so that the first panel 5 can be limited and connected in the front-rear direction. The arrangement in which the extending directions of the locking convex portions 521 of the upper and lower buckles 52 are opposite can limit the first panel 5 in the up-down direction.

[0040] Referring to Figure 1 and Figure 4 In this embodiment, further, the air conditioner indoor unit further includes a wind guiding assembly 8, and the wind guiding assembly 8 is installed on the first panel 5. Specifically, the wind guiding assembly 8 includes a wind guiding plate 82 and a driving motor 81 for driving the wind guiding plate 82 to rotate; the wind guiding plate 82 is disposed inside the air outlet 51, and its left and right ends are respectively rotatably connected to the first panel 5, and one end thereof is connected to the driving motor 81; the driving motor 81 is fixed on the inner side surface of the first panel 5 and is located on one side of the air outlet 51 in the left-right direction. It can be understood that when the first panel 5 is opened relative to the front frame 3 to expose the disassembly opening 32, the wind guiding assembly 8 installed on the first panel 5 is also opened accordingly, so that the wind guiding plate 82 and the like can be conveniently cleaned.

[0041] Referring to Figures 1 to 3 In this embodiment, further, the air duct assembly includes a volute 21. The left and right ends of the chassis 1 are respectively convexly provided with side fixing portions 11. The opposite side surfaces of the two side fixing portions 11 are respectively provided with chute structures, and the left and right ends of the volute 21 are respectively provided with sliding convex structures 211 that can be slidably matched with the chute structures. Thus, the air duct assembly can be very conveniently slid out of the chassis 1 and separated. However, this design is not limited thereto. The sliding convex structures 211 can also be respectively provided on the two side fixing portions 11. Correspondingly, the chute structures are provided on the left and right side ends of the volute 21. Specifically, the left and right ends of the volute 21 are provided with two side plates, and the outer side surface of the side plate protrudes outward to form a slider 211a, and the peripheral edge of the free end of the slider 211a extends outward in the circumferential direction to form a limiting flange 211b; and the inner side surface of the side fixing portion 11 protrudes inward in the left-right direction to form a connecting portion 111, and a chute 112 with an upward opening and a length extending in the front-rear direction is opened on the connecting portion 111; during the sliding-in and sliding-out processes of the air duct component, the bottom end of the slider 211a is slidably matched with the chute 112, and the inner side surface of the limiting flange 211b is slidably matched with the surface of the connecting portion 111 facing the other side fixing portion 11. Here, the slider 211a is preferably provided in a hollow shape to save materials.

[0042] In addition, further, the air duct component also includes a front water receiving tray 22 and a rear water receiving tray (not marked), and the front water receiving tray 22 and the rear water receiving tray are both formed at the upper part of the volute 21 and are integrally arranged with the volute 21. It can be understood that when the air duct component can be removed from the chassis 1, the front water receiving tray 22 and the rear water receiving tray that are integral with the volute 21 can also be separated from the chassis 1, so as to facilitate the cleaning of these components. In addition, the wind wheel 24 of the indoor unit of the air conditioner and the wind wheel motor 25 for driving the wind wheel 24 are also arranged at the upper part of the volute 21 and are located between the front water receiving tray 22 and the rear water receiving tray. The wind wheel 24 and the wind wheel motor 25 can also be removed together with the air duct component, so as to facilitate the maintenance and cleaning of both.

[0043] It should be specially noted here that, in the first embodiment, the first panel 5 is detachably connected to the face frame 3, and the second panel 6 is fixedly connected to the face frame 3, and is preferably provided in an integral manner. At the same time, the mounting opening of the face frame 3 extends from the front side of the face frame 3 to the upper bracket 33, and the mounting opening portion located at the upper bracket 33 is the air inlet of the air conditioner indoor unit in the usual sense. The grille member 41 is arranged inside the air inlet and is detachably connected to the air inlet. Specifically, the grille member is provided with a plurality of fixing buckles for connecting with the upper bracket, and these fixing buckles are preferably provided on the left and right sides of the grille member. The filter screen is provided on the grille member 41 and can be removed along with the grille member 41. Specifically, the grille member 41 is preferably formed integrally with the filter screen. However, the technical solution of the present invention is not limited thereto. In the case of Figure 6 In the second embodiment shown, when the first panel 5 is detachably connected to the face frame 3, the second panel 6 located above the first panel 5 can be rotated and opened relative to the face frame 3. Specifically, the upper end of the second panel 6 is rotatably connected to the face frame 3, and the lower end thereof can be opened relatively away from the face frame 3.

[0044] In addition, in Figure 7 and Figure 8 In the other two embodiments shown, the first panel 5 can also open or cover the disassembly opening 32 by rotating, that is, one end of the first panel 5 is rotatably connected to the face frame 3, and the other end can be opened relatively away from the face frame 3. Figure 7 In the third embodiment shown, the upper end of the first panel 5 is rotatably connected to the face frame 3, and the lower end can be opened relatively away from the face frame 3; at the same time, the second panel 6 is fixedly connected to the face frame 3 and is preferably integrally arranged, and the filter is arranged on the grille member 41 and can be removed along with the grille member 41. Figure 8 The fourth embodiment shown is different from the third embodiment in that the upper end of the second panel 6 is rotatably connected to the face frame 3, and the lower end can be opened relatively away from the face frame 3. It should also be noted that in the technical solution of the present invention, the filter can be removed before the first panel 5 is opened.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
