The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

An air conditioner 200, a rear cabinet 100, and an air inlet grill 10 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to fig. 1 to 3, an air conditioner 200 according to an embodiment of the present invention includes: a rear cabinet 100 and a filter screen 40. Wherein, the rear box 100 is the rear box 100 of the air conditioner 200 according to the embodiment of the present invention. As shown in fig. 3 to 6, the rear cabinet 100 of the air conditioner 200 according to the embodiment of the present invention includes: a rear box bracket 20 and an air inlet grille 10. Wherein, the air inlet grille 10 is the air inlet grille 10 of the rear box 100 of the air conditioner 200 according to the embodiment of the present invention, as shown in fig. 7-10.

Specifically, as shown in fig. 3-6, an opening is provided on the rear box support 20, and a second grill 21 is provided at the opening, and the air inlet grill 10 is installed on the rear box support 20 and located at the opening. As shown in fig. 6 to 10, the air intake grill 10 includes a grill main body 11, the grill main body 11 extending in a longitudinal direction (e.g., an up-down direction shown in fig. 7 and 8), the grill main body 11 including a plurality of first grill bars 111, the plurality of first grill bars 111 being disposed at intervals in the longitudinal direction, and the first grill bars 111 extending in a lateral direction (e.g., a left-right direction shown in fig. 4 and 8). A filter drawing space 50 is formed between the first grid 111 and the second grid 21, and the filter 40 is removably disposed in the filter drawing space 50. The filter screen 40 can be limited and guided by the rear box body bracket 20 and the air inlet grille 10.

For the vertically-shaped air conditioner 200, only by the cooperation of the grille body 11 and the rear cabinet support 20, the space gap at each position of the filter screen drawing space 50 can be uniform, and the requirement of smooth drawing of the filter screen 40 in the vertically-shaped air conditioner 200 can be met, that is, the filter screen 40 of the cylindrically-shaped air conditioner 200 can be smoothly drawn. For some air conditioners 200 with artistic appearances (non-vertical air conditioners 200), the spatial gap difference of the filter screen drawing space 50 is large, which easily causes the deformation of the filter screen 40, affects the drawing smoothness of the filter screen 40, and the filter screen 40 is easily installed and dislocated, which affects the use experience of users.

For example, in the air conditioner 200 shown in fig. 1 and 2, the appearance shape formed by the rear cabinet 100 and the front cabinet 210 is a structure with a narrow middle and two wide ends, and if the artistic shape is guided and limited only by the grille body 11 and the rear cabinet bracket 20, the space gap on both sides of the filter screen drawing space 50 in the longitudinal direction is large, and the space gap in the middle of the longitudinal direction is small, so that the filter screen 40 is easily deformed, which affects the user experience.

Therefore, in the embodiment of the present invention, as shown in fig. 6 to 10, the air grille 10 further includes guide ribs 12. The guide ribs 12 are disposed on the inner side of the grille main body 11, that is, on the side of the grille main body 11 facing the rear case bracket 20, and extend in the transverse direction, and the guide ribs 12 are protruded toward the inner side of the grille main body 11 relative to the inner side of the first grille 111, that is, the guide ribs 12 are protruded toward the rear case bracket 20. The filter screen 40 can be inserted between the guide ribs 12 and the second grid 21, and the guide ribs 12 change the size of the space gap of the filter screen drawing space 50, so that the space gap of the filter screen drawing space 50 is more adaptive to the filter screen 40 without being influenced by the appearance design of the air conditioner 200. In the process of drawing the filter screen 40, the guide ribs 12 can guide the filter screen 40, so that the filter screen 40 is not easy to deform, the structural strength is higher, the drawing is smooth, the filter screen 40 is easier to install in place, and the air filtering effect of the air conditioner 200 is ensured.

For example, in the example shown in fig. 5 and 6, the air conditioner 200 has a narrow middle and wide end, so that the gap between the first and second grills 111 and 21 is gradually increased from top to bottom in the region shown in fig. 6, and by providing the guide ribs 12, such as the upper and lower guide ribs 12 and 12 shown in fig. 6, at different positions in the longitudinal direction, the protruding height of the upper guide rib 12 is smaller than that of the lower guide rib 12, so that the gap between the two guide ribs 12 and the second grill 21 is substantially uniform, and thus the upper and lower portions of the filter screen 40 located in the region shown in fig. 6 are uniformly stressed and are not easily deformed.

In some embodiments, the gap between both ends of the first grill 111 in the lateral direction and the rear case bracket 20 is greater than the gap between the middle portion of the first grill 111 in the lateral direction and the rear case bracket 20, and the height of the guide rib 12 at both ends in the lateral direction is greater than the height of the guide rib 12 at the middle portion in the lateral direction. Therefore, the gaps between the guide ribs 12 and the rear box body bracket 20 are basically kept consistent along the two ends and the middle part in the transverse direction, so that the filter screen 40 is stressed uniformly in all parts in the transverse direction and is not easy to deform.

In some embodiments, as shown in fig. 5 and 6, the rear case bracket 20 has a shape in which a width dimension of a middle portion in a longitudinal direction is small and a width dimension of both ends is large, and the shape of the air intake grill 10 is adapted to the shape of the rear case bracket 20. The guide ribs 12 are arranged at intervals along the longitudinal direction, and the protruding height of the guide ribs 12 at the two ends of the air-inlet grille 10 along the longitudinal direction is greater than that of the guide ribs 12 at the middle part of the air-inlet grille 10 along the longitudinal direction. Therefore, the gap between the guide rib 12 and the rear case bracket 20 is kept substantially consistent along the longitudinal two ends and the middle part, so that the filter screen 40 is uniformly stressed at each position in the longitudinal direction and is not easy to deform.

Of course, the arrangement of the guide ribs 12 at various locations in the longitudinal direction of the air intake grille 10 will be apparent to those skilled in the art from the above description and the example of fig. 6. It will be understood by those skilled in the art how to arrange the guide ribs 12 to guide the filter screen 40 and to smoothly draw the filter screen 40 for other air conditioners 200 with artistic designs.
