Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly to an air conditioner. Background Art

[0002] The air inlet of the air conditioner indoor unit is always open. Although a filter screen is provided at the air inlet, when the air conditioner is not running, the dust in the room will also fall on the filter screen. Therefore, when the air conditioner indoor unit is not running, it is necessary to cover the air inlet to prevent dust from falling on the filter screen.

[0003] In the prior art, some air conditioner indoor units are provided with a closed cover for opening or blocking the air inlet. The closed cover includes a cover plate and a side plate that are connected to each other. The side plate protrudes from the outside of the end cover. If an external force is applied, the closed cover is prone to bending deformation, and the connection stability of the closed cover is poor. Summary of the Utility Model

[0004] The utility model provides an air conditioner to solve the technical problem of poor connection stability of the closed cover in the prior art.

[0005] The utility model provides an air conditioner, comprising:

[0006] A middle frame, on which an air inlet is provided;

[0007] An end cover, which is fixedly arranged on the side surface of the middle frame, and a groove is arranged on the outer surface of the end cover; and,

[0008] A closed cover, which includes a cover plate and a side plate. The cover plate is arranged at the air inlet; the side plate is vertically connected to the cover plate, is located outside the end cover and is slidably connected to the end cover in a first direction; if the cover plate blocks the air inlet, the outer contour of the side plate cooperates with the groove;

[0009] Wherein, the first direction refers to the direction perpendicular to the end face of the air inlet.

[0010] For the air conditioner provided by the utility model, by arranging a groove on the outer surface of the end cover, when the cover plate blocks the air inlet, the outer contour of the side plate cooperates with the groove, and the side plate is accommodated in the groove. The groove plays a role in limiting and protecting the side plate, avoiding bending deformation of the closed cover under the action of external force, and improving the connection stability between the closed cover and the end cover; in addition, the side plate is accommodated in the groove, so that the side plate does not completely protrude from the end cover, avoiding occupying extra space, and thus not increasing the lateral dimension of the air conditioner indoor unit.

[0011] Further, the opening size of the groove on the side close to the cover plate along the first direction is large, and the opening size on the side away from the cover plate is small; the side plate has a large size on the side close to the cover plate along the first direction and a small size on the side away from the cover plate. With such a setting, the connection between the side plate and the cover plate has a wide size, and the end of the side plate away from the cover plate has a narrow size, thereby improving the connection stability and support stability between the side plate and the cover plate.

[0012] Further, the cross-sectional shape of the groove is Y-shaped, and the cross-sectional shape of the side plate is Y-shaped; or, the cross-sectional shape of the groove is V-shaped, and the cross-sectional shape of the side plate is V-shaped.

The first folded edge is located at one end of the side plate body along the first direction and away from the cover plate, and the second folded edge is located at both ends of the side plate body along the second direction; if the cover plate blocks the air inlet, the first folded edge and the second folded edge are respectively in contact with the inner wall surface of the groove; wherein, the second direction is parallel to the plane where the side plate body is located and perpendicular to the first direction. With such a setting, the first folded edge and the second folded edge improve the strength and bending resistance of the side plate; and, by setting the second folded edge, there is an overlap between the convex strip and the second folded edge, avoiding the generation of gaps and improving the aesthetics of the air conditioner.

[0014] Further, the groove is provided with a strip-shaped hole extending along the first direction; the inner wall surface of the side plate body is provided with a convex strip extending along the first direction, and the convex strip extends into the end cover through the strip-shaped hole. With such a setting, the convex strip enhances the strength of the side plate and reduces the bending deformation of the side plate.

[0015] Further, the groove is provided with a first convex block located on both sides of the strip-shaped hole along the second direction; if the cover plate opens the air inlet, the first convex block can abut against the inner surface of the first folded edge along the first direction.

[0019] Furthermore, a first slide groove is provided on one side of the connecting rod close to the side panel, and the convex strip extends into the first slide groove when the connecting rod moves along the first direction. With such arrangement, when the connecting rod moves along the first direction, the convex strip extends into the first slide groove of the connecting rod, so that the convex strip and the first slide groove overlap, thereby avoiding a gap between the side panel and the connecting rod, and improving the aesthetics of the air conditioner.

The middle frame 110 is provided with an air inlet 111; the end cover 120 is fixedly arranged on the side surface of the middle frame 110, and a groove 130 is provided on the outer surface of the end cover 120; the closing cover 20 includes a cover plate 210 and a side plate 220. The cover plate 210 is arranged at the air inlet 111; the side plate 220 is vertically connected to the cover plate 210, is located outside the end cover 120 and is slidably connected to the end cover 120 along a first direction; if the cover plate 210 blocks the air inlet 111, the outer contour of the side plate 220 cooperates with the groove 130; wherein, the first direction refers to the direction perpendicular to the end surface of the air inlet 111.

[0053] An air conditioner provided by an embodiment of the present utility model has a groove 130 provided on the outer surface of the end cover 120. When the cover plate 210 seals the air inlet 111, the outer contour of the side plate 220 cooperates with the groove 130, and the side plate 220 is received in the groove 130. The groove 130 plays a role in limiting and protecting the side plate 220, preventing it from being bent and deformed under the external force of the closing cover 20, and improving the connection stability between the closing cover 20 and the end cover 120. In addition, since the side plate 220 is received in the groove 130, the side plate 220 does not protrude completely from the end cover 120, avoiding occupying extra space and thus not increasing the lateral dimension of the indoor unit of the air conditioner.

[0054] See Appendix Figure 4 and Figure 5 , in an embodiment of the present utility model, the opening size of the groove 130 along the first direction and on the side close to the cover plate 210 is large, and the opening size on the side far from the cover plate 210 is small; the size of the side plate 220 along the first direction and on the side close to the cover plate 210 is large, and the size on the side far from the cover plate 210 is small. With such a setting, the size of the connection between the side plate 220 and the cover plate 210 is wide, and the size of the end of the side plate 220 far from the cover plate 210 is narrow, thereby improving the connection stability and support stability between the side plate 220 and the cover plate 210.

[0055] See Appendix Figure 4 , in an embodiment of the present utility model, in one implementation manner, the cross-sectional shape of the groove 130 is Y-shaped, and the cross-sectional shape of the side plate 220 is Y-shaped. With such a setting, the size of the connection between the side plate 220 and the cover plate 210 is wide, and the size of the end of the side plate 220 far from the cover plate 210 is narrow, thereby improving the connection stability and support stability between the side plate 220 and the cover plate 210.

[0056] See Appendix Figure 4 , in an embodiment of the present utility model, in another implementation manner, the cross-sectional shape of the groove 130 is V-shaped, and the cross-sectional shape of the side plate 220 is V-shaped. With such a setting, the size of the connection between the side plate 220 and the cover plate 210 is wide, and the size of the end of the side plate 220 far from the cover plate 210 is narrow, thereby improving the connection stability and support stability between the side plate 220 and the cover plate 210.

[0057] See Appendix Figure 6 and Figure 7, in the embodiment of the present utility model, the side plate 220 includes a side plate body 230, a first folded edge 231, and a second folded edge 232. Both the first folded edge 231 and the second folded edge 232 are bent towards the inner side of the side plate body 230. The first folded edge 231 is located at one end of the side plate body 230 along the first direction and away from the cover plate 210, and the second folded edge 232 is located at both ends of the side plate body 230 along the second direction. If the cover plate 210 blocks the air inlet 111, the first folded edge 231 and the second folded edge 232 are respectively in contact with the inner wall surface of the groove 130. Wherein, the second direction is parallel to the plane where the side plate body 230 is located and perpendicular to the first direction. With such a setting, the first folded edge 231 and the second folded edge 232 enhance the strength and bending resistance of the side plate 220. And, by setting the second folded edge 232, there is an overlap between the rib 222 and the second folded edge 232, avoiding the generation of gaps and improving the aesthetics of the air conditioner.

The rib 222 extends into the end cover 120 through the strip-shaped hole 131. With such a setting, the rib 222 enhances the strength of the side plate 220 and reduces the bending deformation of the side plate 220.

[0059] In the embodiment of the present utility model, the rib 222 is slidably connected to the strip-shaped hole 131 and extends into the end cover 120.

The multiple decorative grooves 133 are symmetrically arranged on both sides of the strip-shaped hole 131 respectively. Along the first direction and in the direction close to the cover plate 210, the distance between the symmetrically arranged decorative grooves 133 gradually increases. With such a setting, by setting the decorative grooves 133, the visual effect of the strip-shaped hole 131 is weakened, and the aesthetics of the air conditioner is improved.
