The slot 210 is defined by the substrate 220, the side of the face frame 100, and a limiting plate disposed on the side of the substrate 220 away from the side of the face frame 100. The shape and size of the slot 210 are matched with those of the buckling part 112, and when the buckling part 112 is buckled into the slot 210, the slot 210 is buckled with the buckling part 112. In this embodiment, the fastener 110 is disposed on the face frame 100, and the slot 210 is disposed on the upper chassis 200, so that the fastener 110 and the slot 210 are engaged with each other only by pressing the face frame 100 onto the upper chassis 200, which is very convenient and fast.

In order to make the process of matching the fastening portion 112 and the slot 210 smoother and improve the matching accuracy, the slot 210 extends forward from the bottom of the slot 210 away from the first inner wall surface 221 of the slot wall on the side of the upper chassis 200;

the engaging portion 112 has a guide surface 113 that engages with the first inner wall surface 221 on a side facing the side of the face frame 100, and the guide surface 113 is attached to the first inner wall surface 221.

Specifically, in the present embodiment, the first inner wall surface 221 extends forward and upward from the substrate 220, and the front is the direction of the face frame 100, that is, the first inner wall surface 221 is an inclined surface. The engaging portion 112 has a guide surface 113 that fits to the first inner wall surface 221, and the guide surface 113 is also an inclined surface, so that when the engaging portion 112 enters the engaging groove 210, the guide surface 113 abuts against the first inner wall surface 221, and the engaging portion 112 moves along the first inner wall surface 221.

Specifically, in the present embodiment, the two fasteners 110 may be disposed independently, or may be disposed integrally, and when the two fasteners 110 are disposed integrally, the connecting arm 111 is disposed between the two connecting arms. The engaging portions 112 of the two fasteners 110 are respectively engaged with two sub-grooves, and the portion of each sub-groove corresponding to the first inner wall surface 221 is attached to the guide surface 113 of the engaging portion 112. By arranging the two fasteners 110, the connection between the face frame 100 and the upper chassis 200 is more stable and reliable.

In order to improve the stability of the connection between the face frame 100 and the upper chassis 200, the fastening portion 260 further includes a baffle 250, and the baffle 250 is disposed above the partition 230;

the fastener 110 further includes a stop block 120, and the stop block 120 is disposed between the two fastening portions 112.

One end of the baffle 250 is fixedly connected with the side of the upper chassis 200, and the other end extends outwards, and the length of the baffle 250 is greater than that of the partition 230, that is, the baffle 250 needs to extend out of the partition 230. The shape of the stopper 120 is not particularly limited, and the surface facing the baffle 250 is a plane. When the fastener 110 and the fastening position 260 are matched, the baffle plate 250 is positioned right above the stopper 120, and the baffle plate 250 limits the up-and-down displacement of the stopper 120, i.e. limits the upward movement of the face frame 100 relative to the upper base plate 200.

Of course, in some embodiments, in order to improve the installation strength of the baffle 250, the top of the partition 230 is fixedly connected to the bottom surface of the baffle 250. In this embodiment, the partition 230 is vertically disposed with the substrate 220, the baffle 250 is disposed parallel to the substrate 220, and the partition 230 is disposed between and fixedly connected to the substrate 220 and the baffle 250. In some embodiments, the baffle 250, the baffle 230, and the base plate 220 are integrally formed. Through with baffle 250 and baffle 230 fixed connection, when improving baffle 250's installation intensity, make draw-in groove 210 enclose by base plate 220, baffle 230, the side and the baffle 250 of going up chassis 200 and close and form, make draw-in groove 210's spacing nature further improved, be favorable to improving draw-in groove 210 and fastener 110 complex stability.

In order to improve the space utilization rate, an avoiding groove 240 is formed on the outer side wall of the groove wall of the clamping groove 210 away from the side edge of the upper chassis 200; the notch of the escape groove 240 is disposed toward the stopper 120.

Specifically, in the present embodiment, the avoiding groove 240 and the first inner wall surface 221 are located on two plate surfaces of the same groove wall, and the shape of the avoiding groove 240 is not limited herein, so as to be adapted to the shape and size of the stopper 120 and limit the movement of the stopper 120. The avoiding groove 240 and the clamping groove 210 share the same groove wall, and the groove wall of the avoiding groove 240 is fixedly connected with the partition plate 230. The avoiding groove 240 is recessed toward the inner wall of the card slot 210, so that the avoiding groove 240 is embedded in one side of the card slot 210. When the stop block 120 is disposed in the avoiding groove 240, the avoiding groove 240 can limit the position of the stop block 120, and the position of the stop block 120 is more stable and reliable, so that the stop block 120 can be embedded in the slot 210, thereby saving space and improving space utilization rate.

For example, to improve the convenience of disassembly, the air conditioner further includes an elastic arm 130, one end of the elastic arm 130 is fixedly connected with the side edge of the face frame 100, and the other end extends between the two fasteners 110;

the stop block 120 is disposed on a side of the elastic arm 130 away from the face frame 100.

Specifically, in the present embodiment, when the fastening element 110 and the fastening position 260 need to be detached, the face frame 100 can be detached only when the stop block 120 needs to be moved out of the range covered by the blocking plate 250. By disposing the stopper 120 on the elastic arm 130, when it is necessary to move the stopper 120, it is only necessary to break the elastic arm 130. The movement of the stop block 120 becomes very convenient, the disassembly of the face frame 100 and the upper chassis 200 also becomes very convenient, and the improvement of the work efficiency of disassembling the face frame 100 is facilitated.

In order to more conveniently detach the face frame 100 from the upper chassis 200, the distance between the top end of the elastic arm 130 and the stopper 120 is greater than the thickness of the baffle 250. I.e., the resilient arm 130 extends outside the baffle 250, such that the user can easily reach the resilient arm 130 in an eye-visible position and move the resilient arm 130 by swinging the free end of the resilient arm 130 to move the stopper 120. The distance between the top end of the elastic arm 130 and the stopper 120 is greater than the thickness of the stopper 250, so that the movement of the elastic arm 130 is facilitated.

In order to reduce the extrusion noise generated between the upper chassis 200 and the air inlet grille 300 due to expansion with heat and contraction with cold, the indoor unit of the air conditioner further comprises the air inlet grille 300, and the air inlet grille 300 and the upper chassis 200 are integrally formed.

In this embodiment, the air inlet grille 300 and the upper chassis 200 are integrally injection molded, when the air conditioner is expanded with heat and contracted with cold due to the operation of the air conditioner, the air inlet grille 300 and the upper chassis 200 are expanded or contracted with cold simultaneously, so that the air inlet grille 300 and the upper chassis 200 are not extruded with each other, and thus, no deformation or extrusion friction sound is generated, thereby eliminating the noise generated between the upper chassis 200 and the air inlet grille 300 due to the expansion with heat and the contraction with cold, and facilitating the quieter and more comfortable use of the air conditioner by a user.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
