As shown in FIGS. 1 and 2 , the housing 10 of the air conditioner indoor unit 1 of the present invention generally has a top plate 14 located above, a bottom plate 12 located below, a front plate 18 and a side frame 16 during conventional installation. The front board 18 extends approximately perpendicular to the top board 14 and the bottom board 12 and has an air outlet thereon. The side frame 16 also extends approximately perpendicular to the top plate 14 and the bottom plate 12 , and is provided with a wind inlet surface thereon. Preferably, the side frame 16 consists of two side frames 161 , 162 that are angled, and in a preferred embodiment, the two side frames 161 , 162 are substantially 90 degrees. The side frame 16 may be made of resin or metal, and may be molded by resin injection molding, for example. The air conditioner indoor unit 1 is a vertical wall-mounted air conditioner indoor unit 1 suitable for being installed at the corner of the room. At least a part of the side frame 16 is provided with a fixing structure fixed to the vertical wall. In the installed state, the air conditioner indoor unit The housing 10 of 1 is in an upright state.

As shown in FIG. 6 , the housing of the air conditioner indoor unit 1 of the present invention forms at least one accommodating cavity, and the accommodating cavity is provided with a heat exchanger 60 , a fan assembly 70 and electrical components. The heat exchanger 60 is basically extended along the side frame 16 inside the side frame 16 , and the fan assembly 70 is disposed in the middle of the heat exchanger 60 . Driven by the fan assembly 70 , air enters from the air inlet 20 on the side frame 16 , passes through the heat exchanger 60 to exchange heat, and then is sent out from the air outlet on the front panel 18 . Preferably, as shown in FIG. 1 , the front panel 18 is also provided with a panel 80 which is movable between an open position and a closed position. When the panel 80 is in the open position, the air outlet on the front panel 18 is open to the outside, and when the panel is in the closed position, the air outlet on the front panel 18 is closed.

The side frame 10 mainly includes two side frames 161, 162, which are arranged at an angle, preferably, the two side frames 161, 162 are arranged at an angle of 90 degrees. At least one side frame 161, 162 is provided with the air inlet portion 20, thereby forming an air supply surface. Preferably, the two side frames 161 , 162 are both provided with the air inlet 20 .

The air intake portion 20 includes a suction grill 22 and a filter assembly 26 that are detachably engaged with each other. The filter screen assembly 26 can be provided with various types of filter screens according to actual needs, such as one or more of primary filter screens, PM2.5 filter screens, and UP titanium filter screens. The filter assembly 26 filters the airflow entering the indoor unit 1 of the air conditioner, thereby improving the air quality of the indoor unit 1 . After a period of use, the filter screen assembly 26 can be removed from the suction grill 22 for cleaning or replacement.

As shown in FIG. 2 and FIG. 3 , according to the present invention, the suction grille 22 of the air inlet portion 20 has a frame 21 , and the frame 21 surrounds and forms a suction surface 23 of the air inlet portion 20 . The air suction surface 23 is divided into two parts by a spacer 25 in the middle: the grille part 222 and the opening part 221 . The grille portion 222 includes a plurality of ribs intersecting each other in the grille portion 222 to form a grille shape; and the opening portion 221 is a substantially open area, preferably without ribs therein. The pattern of the ribs formed in the grid part 222 can be set arbitrarily according to needs, for example, only have vertical ribs, or only have horizontal ribs.

As shown in FIG. 4 , the filter assembly 26 has a shape matching the suction grille 22 and can cover the entire suction surface 23 . The filter assembly 26 according to the present invention particularly includes a first filter part 261 and a second filter part 262 , the first filter part 261 covers the opening part 221 , and the second filter part 262 covers the grille part 222 . The two screen parts 261, 262 have different thicknesses in the direction perpendicular to the screen surface, and the thickness of the first screen part 261 covering the opening part 221 is greater than the thickness of the second screen part 262 covering the grille part 222. . In this way, on one side of the filter screen assembly 26, a stepped portion 263 will be formed between the first filter screen portion 261 and the second filter screen portion 262, while the opposite side of the filter screen assembly 26 is substantially flat. , does not have a step portion. When the filter assembly 26 is inserted and fitted onto the suction grill 22 , for example, through the guide groove, the stepped portion 263 abuts against the partition bar 25 on the suction grill 22 . An engaging structure may also be provided on the step portion 263 to engage with a matching engaging structure provided on the spacer, so as to help limit the position of the filter assembly 26 . In the illustrated embodiment, the spacers 25 are vertical, but it can be understood that the spacers can also be arranged horizontally, so that the openings and the grille are arranged up and down.

The first filter mesh part 261 has first filter mesh ribs 265, and the first filter mesh ribs 265 divide the first filter mesh part 261 into a plurality of small cells.

In this way, if the air conditioner indoor unit 1 is viewed from the back side, if the filter screen assembly 26 is inserted into the suction grille 22, the second filter screen ribs 267 will be blocked by the ribs 227 of the grille portion 22 and are basically invisible. In addition, in the case that the reliability of the filter screen is not affected, the number of the second filter screen ribs 267 can be reduced, that is, the number of the second filter screen ribs 267 is smaller than the number of the ribs 227 of the grille part 222, but the second filter screen The ribs 267 still coincide with a portion of the ribs 227 of the grid portion 222 . In this way, not only is it beautiful, but also the air intake area of the air intake portion 22 is maximized, thereby reducing the air intake resistance.

The filter mesh assembly 26 may be integrally formed by inserting the filter mesh with a resin material. In terms of rigidity, generally speaking, the rigidity of the first filter screen part 261 is greater than that of the second filter screen part 262. Further, the rigidity of the first filter screen rib 265 on the first filter screen part 261 is greater than that of the second filter screen part 261. Rigidity of the second mesh ribs 267 of the mesh portion 262. The rigidity of the first filter mesh rib 265 on the first filter mesh portion 261 can be set so that the first filter mesh portion 261 cannot be deformed substantially, and the rigidity of the second filter mesh rib 267 is set so that the second filter mesh portion 262 can Flexed, this will facilitate insertion of the second style portion 262 into the grille portion 222 .
