[0015] In the present application, the air inlet panel comprises a first matching part, the indoor unit shell comprises a first rotation-stopping part, and the first rotation-stopping part is matched with the first matching part, so as to limit the rotation of the first edge around the connecting part. That is, even if the air inlet panel and the indoor unit shell are connected, the stress difference between the connecting part and the first edge is large, that is, the internal stress of the connecting part is large, and the internal stress of the first edge is small, so that the air inlet panel has the tendency of uneven deformation, and the first edge has the tendency of warping away from the indoor unit shell. Due to the rotation-stopping matching between the first matching part and the first rotation-stopping part, the warping of the first edge can be hindered and avoided, that is, the problem of edge warping of the air inlet panel is solved.

[0071] The air conditioner generally includes an outdoor unit and an indoor unit. The outdoor unit is used to deliver the heat-exchanged refrigerant to the indoor unit to exchange heat with the air flowing into the indoor unit, thereby changing the temperature of the air flowing out of the indoor unit. The indoor unit is generally divided into a cabinet machine and a hanging machine. The hanging machine is generally hung on the wall, and the cabinet machine is generally placed on the ground.

[0072] The hanging machine includes an indoor unit shell and an air inlet panel. The indoor unit shell is provided with a shell air inlet. The air inlet panel is installed at the shell air inlet. When the air inlet panel is connected to the indoor unit shell, a large compressive stress is generated at the connection between the air inlet panel and the indoor unit shell. The edge of the air inlet panel is relatively far away from the connection, so the internal stress of the edge region of the air inlet panel is relatively small. This uneven stress distribution causes the air inlet panel to deform unevenly, resulting in the edge of the air inlet panel warping.

[0073] The air conditioner indoor unit provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0074] As shown in Figures 1 to 7 The air conditioner indoor unit provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0075] The indoor unit shell 100 is provided with a shell air inlet 101, and the indoor unit shell 100 is used to form the overall appearance of the air conditioner indoor unit. The indoor unit shell 100 is hollow inside to form a containing cavity configured to contain a plurality of components in the air conditioner indoor unit, such as a circuit, an evaporator, and the like. The shell air inlet 101 is used for indoor air to enter the indoor unit shell 100.

[0076] The air inlet panel 200 is arranged at the shell air inlet 101, and the air inlet panel 200 has a panel air inlet 201 arranged opposite to the shell air inlet 101. The air inlet panel 200 can prevent insects and other foreign matters from entering the indoor unit shell 100, thereby avoiding damage to the air conditioning equipment. The panel air inlet 201 and the shell air inlet 101 are in communication, thereby facilitating the indoor air to enter the indoor unit shell 100.

[0077] The air inlet panel 200 includes:

[0078] The connecting portion 210 is connected with the indoor unit shell 100, thereby fixing the air inlet panel 200 to the indoor unit shell 100.

[0079] The first edge 202 is a part of the air inlet panel 200 located at the periphery thereof.

[0080] The first matching portion 220 is arranged towards the indoor unit shell 100 and located between the first edge 202 and the connecting portion 210, and the first matching portion 220 is used to stop rotation with the first rotation stopping portion 110.

[0081] The indoor unit shell 100 includes:

[0082] The first rotation stopping portion 110 is arranged towards the air inlet panel 200, and here the arrangement position of the first rotation stopping portion 110 matches the arrangement position of the first matching portion 220 to cooperate with the first matching portion 220.

[0083] The first rotation stopping portion 110 cooperates with the first matching portion 220 to limit the first edge 202 to rotate around the connecting portion 210 in a direction away from the indoor unit shell 100.

[0084] In the present application, the air inlet panel 200 comprises a first matching part 220, and the indoor unit shell 100 comprises a first rotation-stopping part 110, which matches with the first matching part 220, so as to limit the rotation of the first edge 202 around the connecting part 210. That is, even when the air inlet panel 200 is connected with the indoor unit shell 100, the stress difference between the connecting part 210 and the first edge 202 is large, that is, the internal stress of the connecting part 210 is large, and the internal stress of the first edge 202 is small, so that the air inlet panel 200 has a tendency of uneven deformation, and the first edge 202 has a tendency of warping away from the indoor unit shell 100. However, due to the rotation-stopping matching between the first matching part 220 and the first rotation-stopping part 110, the warping of the first edge 202 is hindered and avoided, that is, the edge warping problem of the air inlet panel 200 is solved.

[0085] In some embodiments, one of the first matching part 220 and the first rotation-stopping part 110 is a plug hole, and the other is a plug shaft, which is plugged and matched with the plug hole, and the rotation of the first edge 202 around the connecting part 210 away from the indoor unit shell 100 is limited by the “hole-shaft matching” between the plug hole and the plug shaft.

[0086] In an alternative embodiment, please refer to Figure 3 、 Figure 5 and Figure 7 , one of the first matching part 220 and the first rotation-stopping part 110 is a plug slot, and the other is a protruding part, which is plugged and matched with the plug slot, and the plug direction of the protruding part and the plug slot is parallel to the arrangement direction of the indoor unit shell 100 and the air inlet panel 200.

[0087] In the present embodiment, the rotation of the first edge 202 around the connecting part 210 away from the indoor unit shell 100 is limited by the matching between the protruding part and the plug slot, and compared with the “hole-shaft matching” described above, the structure of the plug slot and the protruding part in the present embodiment is simpler, and the assembly is easier. Of course, the first matching part 220 and the first rotation-stopping part 110 can both be protruding parts, and the first rotation-stopping part 110 can be located between the first matching part 220 and the first edge 202.

[0088] In an alternative embodiment, please refer to Figure 4 and Figure 5 , the air inlet panel 200 comprises:

[0089] a panel body 230 having the first edge 202, wherein the panel body 230 is the main part of the air inlet panel 200, and is used to form the panel air inlet 201.

[0090] a protruding rib 240, which is arranged on the side of the panel body 230 facing the indoor unit shell 100, and the plug slot is arranged on the protruding rib 240.

[0091] The embodiment can ensure the structural strength of the air inlet panel 200, reduce the risk of damage of the air inlet panel 200 under the action of external force, compared with the technical solution of "directly forming the slot on the panel body 230 by removing material", and the setting of the protruding ribs 240 on the panel body 230 can also increase the cross-sectional area of the air inlet panel 200, so as to increase the structural strength of the air inlet panel 200, and further reduce the risk of damage of the air inlet panel 200 under the action of external force.

[0092] In order to ensure the effect of limiting the warping of the first edge 202, in an optional embodiment, please refer to Figure 4 and Figure 5 The air inlet panel 200 further comprises:

[0093] The reinforcing rib 250 is used to improve the structural strength of the air inlet panel 200 and prevent the air inlet panel 200 from being damaged under the action of external force, and the reinforcing rib 250 is arranged on the side of the panel body 230 facing the indoor machine shell 100 and connected with one end of the protruding rib 240.

[0094] The slot on the protruding rib 240 is used for rotation-stopping cooperation with the protruding part, and a large internal stress will be generated between the protruding part and the protruding rib 240 during rotation-stopping, and if the structural strength of the protruding rib 240 is low, the protruding rib 240 will be damaged, so as to be unable to provide rotation-stopping cooperation, and thus unable to limit the warping of the first edge 202, therefore, the embodiment is provided with the reinforcing rib 250 on the side of the panel body 230 facing the indoor machine shell 100, and the protruding rib 240 is connected with the reinforcing rib 250, so that the protruding rib 240 and the reinforcing rib 250 can jointly bear the internal stress, that is, the internal stress borne by the protruding rib 240 will be reduced, so as to prevent the protruding rib 240 from being damaged during rotation-stopping, and ensure the effect of limiting the warping of the first edge 202.

[0095] In an optional embodiment, please refer to Figure 4 The air inlet panel 200 further comprises:

[0096] The annular surrounding edge 260 surrounds the edge of the panel body and extends towards the indoor machine shell 100, and after the annular surrounding edge 260 is arranged on the edge of the panel body 230, the cross-sectional area of the air inlet panel 200 can be increased, so as to improve the structural strength of the air inlet panel 200 and make the air inlet panel 200 more stable.

[0097] One end of the protruding rib 240 away from the reinforcing rib 250 is connected with the annular surrounding edge 260.

[0098] In the embodiment, one end of the protruding rib 240, which is away from the reinforcing rib 250, is connected with the annular surrounding edge 260, that is, both ends of the protruding rib 240 are connected with the reinforcing rib 250 and the annular surrounding edge 260 respectively, so that both ends of the protruding rib 240 are not free ends, and the protruding rib 240, the reinforcing rib 250 and the annular surrounding edge 260 can jointly bear the internal stress, so that the internal stress borne by the protruding rib 240 is further reduced, to further prevent the protruding rib 240 from being damaged in the process of rotation stopping, and to further ensure the effect of limiting the warping of the first edge 202.

[0099] In an alternative embodiment, please refer to Figure 4 , the annular surrounding edge 260 comprises:

[0100] The first surrounding edge 261 is oppositely arranged with the second surrounding edge 262.

[0101] The second surrounding edge 262 is oppositely arranged with the first surrounding edge 261. For example, the first surrounding edge 261 can be arranged in parallel with the second surrounding edge 262.

[0102] The third surrounding edge 263 is arranged on the first edge 202 and located between the first surrounding edge 261 and the second surrounding edge 262, and both ends of the third surrounding edge 263 are connected with the first surrounding edge 261 and the second surrounding edge 262 respectively.

[0103] The protruding rib 240 is connected with the third surrounding edge 263, and both ends of the reinforcing rib 250 are connected with the first surrounding edge 261 and the second surrounding edge 262 respectively.

[0104] In the embodiment, both ends of the reinforcing rib 250 are connected with the first surrounding edge 261 and the second surrounding edge 262 respectively, and the reinforcing rib 250 is further connected with the protruding rib 240, and the protruding rib 240 is further connected with the third surrounding edge 263, that is, the first surrounding edge 261, the second surrounding edge 262, the third surrounding edge 263, the protruding rib 240 and the reinforcing rib 250 form a "day" shaped support structure, when any one of the first surrounding edge 261, the second surrounding edge 262, the third surrounding edge 263, the protruding rib 240 and the reinforcing rib 250 bears the internal stress, the other four can share the internal stress, to reduce the risk of damage of each component. Of course, the reinforcing rib 250 can be connected with only the first surrounding edge 261, the second surrounding edge 262 or the third surrounding edge 263, and the present application does not limit this.

[0105] In an alternative embodiment, please refer to Figure 5 , the width of the slot of the slot gradually increases along the direction from the panel body 230 to the indoor unit shell 100, that is, the slot has a larger width on the side facing the indoor unit shell 100.

[0106] In the embodiment, the slot of the slot is toward the side of the indoor unit shell 100 has a larger width, and when the air inlet panel 200 and the indoor unit shell 100 are assembled, the protruding part on the indoor unit shell 100 will first enter the slot toward the side of the indoor unit shell 100, and the slot has a larger width on this side, which facilitates the protruding part to enter the slot, thereby facilitating the connection of the air inlet panel 200 and the indoor unit shell 100. Of course, the width of the slot can remain unchanged along the direction from the panel body 230 to the indoor unit shell 100.

[0107] In an alternative embodiment, referring to Figure 4 , the number of slots is multiple, and the multiple slots are distributed along the first direction, which is perpendicular to the arrangement direction of the first edge 202 and the connecting part 210. The arrangement of multiple slots can provide multiple rotation stopping points between the air inlet panel 200 and the indoor unit shell 100, thereby improving the effect of preventing the first edge 202 from being warped.

[0108] The protruding part includes a plug-in protruding rib 240, which extends along the first direction, and one plug-in protruding rib 240 is plugged into cooperation with the multiple slots.

[0109] In the embodiment, one plug-in protruding rib 240 is plugged into cooperation with the multiple slots, that is, the plug-in protruding rib 240 continuously extends. Compared with the technical solution that "the plug-in protruding rib 240 includes multiple sub-insert ribs arranged at intervals, and each sub-insert rib is plugged into cooperation with each slot", the plug-in protruding rib 240 of the embodiment is a continuous whole structure, which can improve the structural strength of the plug-in protruding rib 240 and prevent the plug-in protruding rib 240 from being damaged, thereby ensuring the effect of preventing the first edge 202 from being warped.

[0110] In an alternative embodiment, referring to Figure 3 and Figure 5 , the connecting part 210 includes:

[0111] The guide column 211 extends toward the indoor unit shell 100, and the guide column 211 is guided in cooperation with the guide hole 120 to realize the positioning between the air inlet panel 200 and the indoor unit shell 100, thereby preventing the air inlet panel 200 from being installed out of position.

[0112] The indoor unit shell 100 is provided with the guide hole 120, and the guide hole 120 is plugged into cooperation with the guide column 211, that is, the inner wall of the guide hole 120 is fitted with the outer wall of the guide column 211.

[0113] The air conditioner indoor unit further includes:

[0114] A fastener (not shown in the figure) passes through the guide column 211 and is threadedly connected with the indoor unit shell 100 at one end. For example, the fastener can be a screw.

[0115] In the embodiment, the connecting part 210 comprises a guide column 211, and the indoor unit shell 100 is provided with a guide hole 120. In the process of installing the air inlet panel 200 to the indoor unit shell 100, the guide column 211 cooperates with the guide hole 120, so that the air inlet panel 200 is located at a preset position, to avoid the air inlet panel 200 from being installed out of position. In addition, after the air inlet panel 200 is provided with the guide column 211 and the threaded fastener passes through the guide column 211, the threaded fastener has a relatively large screwing length with the air inlet panel 200, so as to improve the connection strength between the air inlet panel 200 and the indoor unit shell 100 and improve the connection stability between the air inlet panel 200 and the indoor unit shell 100.

[0116] In an alternative embodiment, referring to Figure 5 , the connecting part 210 further comprises:

[0117] a first clamping part 212, which clamps and cooperates with the indoor unit shell 100, so as to preliminarily connect the air inlet panel 200 and the indoor unit shell 100. For example, the first clamping part 212 can be a buckle or a clamping groove.

[0118] Specific installation process is as follows: the preliminary positioning of the air inlet panel 200 is completed by the guide column 211 and the guide hole 120; the air inlet panel 200 is preliminarily connected to the indoor unit shell 100 by pressing the air inlet panel 200 through the first clamping part 212; and the air inlet panel 200 is secondarily fixed by the fastener. It can be seen that, before the air inlet panel 200 is fixed by the fastener, the air inlet panel 200 is preliminarily fixed by the first clamping part 212, which can prevent the air inlet panel 200 from being separated from the indoor unit shell 100, so as to facilitate the fastener to be punched, to reduce the installation difficulty of the air inlet panel 200.

[0119] In other embodiments, the connecting part 210 can only comprise the first clamping part 212, or can only comprise the guide column 211, and the specific structure of the connecting part 210 is not limited in the application.

[0120] In an alternative embodiment, referring to Figure 7 , the air conditioner indoor unit further comprises:
