Detailed Description

The invention is described in detail below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

Referring to fig. 1 to 4, an air conditioning indoor unit 100 according to an embodiment of the present invention defines that a side of the air conditioning indoor unit 100 facing a user is a front side and an opposite side is a rear side when the air conditioning indoor unit is installed for use. The indoor unit 100 of the air conditioner comprises an outer cover 1, a panel 3, a base 4 and a heat exchange module (not shown in the figure);

the rear side surface of the outer cover 1 is opened, the base 4 is connected with the outer cover 1 from the rear surface of the outer cover 1, so that the base 4 and the outer cover 1 form a cavity, and the heat exchange module is arranged in the cavity and used for realizing indoor air temperature regulation; a heat exchange air inlet 101 formed by a grid is arranged above the outer cover 1 corresponding to the position of the heat exchange module, and a heat exchange air outlet 102 is arranged below the outer cover 1 (the heat exchange air outlet 102 shown in fig. 1 is in a closed state). In the cooling/heating mode, indoor air can enter the heat exchange module through the heat exchange air inlet 101, and is circulated to the indoor through the heat exchange air outlet 102 after exchanging heat with the heat exchange module, so that the indoor temperature can be adjusted.

The panel 3, which is connected to the outer side of the housing 1 in a surrounding manner, may be in the form of a snap or screw connection as is commonly used in the art. In the illustrated embodiment, referring to fig. 2, the panel 3 includes an upper panel 31, a front panel 32, and a lower panel 33; the upper panel 31 is connected to the upper side of the housing 1, and a grid is provided on the upper panel 31 corresponding to the heat exchange opening on the upper side of the housing 1, and a through hole 330 exposing the heat exchange air outlet 102 is provided on the lower panel 33. Therefore, the panel 3 can ensure the appearance and the strength of the air conditioner indoor unit and does not influence the function of the air conditioner.

Along with the improvement of the requirement of the user on the air treatment quality, a form of adding a fresh air module in the indoor unit of the air conditioner is generated, and the fresh air (fresh air) outside is conveyed to the indoor space through the fresh air module. Referring to fig. 3-8, in the illustrated embodiment, the fresh air module 2 is located inside the housing 1 and is connected to the left side of the base 4, it being understood that the fresh air module 2 may also be located on the right side.

Specifically, the fresh air module 2 includes a volute 21 and a cover plate 22;

a volute 21, wherein an air suction opening 211 is formed on the left side of the volute 21, an air exhaust opening 212 is formed on the upper side of the volute 21, an air channel is formed inside the volute 21, and the air channel is communicated with the air suction opening 211 and the air exhaust opening 212; a fan is arranged in the air duct.

The cover plate 22 is connected to one side of the volute casing 21 with the air suction opening 211, and an air inlet cavity 20 is defined between the cover plate 22 and the volute casing 21; the rear side of the cover plate 22 is provided with a pipeline interface 220, and the pipeline interface 220 is used for connecting a fresh air pipe, so that fresh air outside enters the air inlet cavity 20 through the fresh air pipe.

When filter screen assembly 8 packs into in the indoor set, filter screen cover plate 82 can hold in cavity 311 in filter screen assembly 8, through set up cavity 311 on top panel 31, can expose filter screen cover plate 82, in order to make things convenient for the user to carry out the pull operation to filter screen cover plate 82, and, cavity 311's setting makes filter screen cover plate 82 be connected with dustcoat 1 in cavity 311 department, effectively prevent filter screen assembly 8 because of connecting the problem that insecure and easily take off, can avoid filter screen cover plate 82 protrusion to influence the outward appearance effect of indoor set in top panel 31's surface simultaneously.

When the filter screen assembly 8 is plugged in from the cavity 311, the filter screen 81 can deform, the problem that the filter screen assembly 8 is too hard to be plugged in too far or the filter screen assembly 8 is plugged in too far can be caused, and the use quality of the filter screen 81 can be further affected, as shown in fig. 24 to 26, a positioning structure is arranged between the filter screen cover plate 82 and the cavity 311, specifically, a clamping groove 823 is arranged at the rear end of the filter screen cover plate 82, correspondingly, a clamping strip 312 is arranged on the inner wall of the cavity 311, and the clamping groove 823 is matched with the clamping strip 312 to enable the filter screen cover plate 82 to be positioned in the cavity 311. When the filter screen component 8 is assembled, the filter screen component 8 is plugged into the rear side direction of the indoor unit, when the clamping groove 823 clamps the clamping strip 312, the filter screen component 8 cannot be pushed any more, and deformation of the filter screen 81 caused by excessive plugging of the filter screen component 8 can be effectively avoided; moreover, after the position of the filter screen cover plate 82 in the cavity 311 is determined by the matching of the clamping groove 823 and the clamping strip 312, the position of the magnetic attraction device between the filter screen cover plate 82 and the outer cover 1 can be conveniently determined.
