This plug-in connection method can limit the air outlet panel 300 in the front-to-back direction and the left-to-right direction.

[0076] On the other hand, since a plurality of first slot structures 250 are arranged vertically at intervals on both lateral sides of the third air outlet 230, the middle of the air outlet panel 300 can be further firmly limited to prevent the air outlet panel 300 from detaching or shaking.

[0077] In some embodiments of the front shell assembly of the present invention, as Figure 4 , Figure 8 and Fig.12 As shown, a first buckle 260 is disposed at the lower end of the panel mounting portion 200 , and the first buckle 260 includes a vertically disposed elastic plate 261 and a support platform 262 extending forward from the elastic plate 261 .

[0078] A transverse supporting rib 360 is provided at the lower end of the back side of the air outlet panel 300, so that when the air outlet panel 300 is slid upward and installed on the panel mounting portion 200, the front of the elastic plate 261 abuts against the rear end of the transverse supporting rib 360, and the upper end of the support platform 262 supports the lower end of the transverse supporting rib 360.

[0079] In this embodiment, the panel mounting portion 200 supports and limits the air outlet panel 300 in the vertical direction through the first buckle 260. Specifically, the elastic plate 261 has a forward elastic force, which can cause the front of the elastic plate 261 to contact the rear end of the transverse support rib 360, and cause the support platform 262 on the front side of the elastic plate 261 to extend forward and be received on the lower side of the transverse support rib 360 of the air outlet panel 300.

[0080] During installation, after the air outlet panel 300 is slid upward so that the sliding structure 220 is inserted into the slide groove of the slide groove structure 320, and / or the hook of the hook structure 350 is inserted into the first slot 251, the lower end of the air outlet panel 300 will be squeezed backward. Of course, the lower end of the air outlet panel 300 can also be gently pressed or tapped backward so that the rear end of the transverse support rib 360 contacts the elastic plate 261, and the lower end of the transverse support rib 360 slides into the upper surface of the support platform 262.

[0081] The front housing assembly of the utility model is provided with a sliding structure 220, a first slot structure 250 and a first buckle 260 on the panel mounting portion 200, and a sliding structure 320, a hook structure 350 and a transverse support rib 360 on the air outlet panel 300, and the air outlet panel 300 can be fixedly connected to the panel mounting portion 200 through a plug-in connection and a buckle connection. This connection method does not use screws, can be disassembled and assembled by hand, is easy to operate, and can prevent screws from accidentally falling into the air outlet during disassembly and assembly.

[0082] Preferably, if Figure 8 As shown, reinforcing ribs may be provided on the lower side of the support platform 262 to improve the strength of the support platform 262 .

[0083] In some embodiments of the front shell assembly of the present invention, as Figure 4 , Figure 7 and Fig.12 As shown, a limiting groove 271 is further provided at the lower end of the panel mounting portion 200 , and the limiting groove 271 extends in the vertical direction. A threaded hole 272 is provided at the upper portion of the limiting groove 271 .

[0084] A limiting boss 371 is provided on the back of the air outlet panel 300, and a mounting hole 372 is provided on the limiting boss 371, so that when the air outlet panel 300 is slid upward and installed on the panel mounting part 200, the limiting boss 371 is inserted into the limiting groove 271, and after sliding upward along the limiting groove 271 into place, the mounting hole 372 and the threaded hole 272 are connected by fasteners.

[0085] The threaded hole 272 is located at the lower side of the bottom ends of the first air outlet 110 , the second air outlet 120 and the third air outlet 230 .

[0086] In this embodiment, the panel mounting portion 200 is also fixedly connected to the air outlet panel 300 by means of threaded fasteners to prevent the user from accidentally touching the first buckle 260 and causing the air outlet panel 300 to fall off downward.

[0087] Specifically, during installation, when the air outlet panel 300 is slid upward so that the sliding structure 220 is inserted into the slide groove in the slide groove structure 320, and / or the hook of the hook structure 350 is inserted into the first slot 251, the limiting boss 371 on the back of the air outlet panel 300 is slidably inserted into the limiting groove 271 and slides upward along the limiting groove 271. The limiting groove 271 can limit the limiting boss 371 in the left and right directions to prevent the air outlet panel 300 from tilting during the upward sliding process.

[0088] After the sliding structure 220 is inserted into the slide groove of the slide groove structure 320, and / or the hook of the hook structure 350 is inserted into the first slot 251, the lower end of the air outlet panel 300 is gently pressed or tapped backwards, so that the first buckle 260 is engaged with the transverse support rib 360. At this time, the limiting boss 371 slides upward to the upper end of the limiting groove 271, and the mounting hole 372 is aligned with the threaded hole 272. Finally, the fastener is installed in the mounting hole 372 and the threaded hole 272.

[0089] After the installation is completed, the limiting groove 271 can also limit the limiting boss 371 in the left and right directions to improve the firmness of the installation of the air outlet panel 300.

[0090] In particular, since the threaded hole 272 is located at the lower side of the bottom ends of the first air outlet 110, the second air outlet 120 and the third air outlet 230, when the fastener is installed in the mounting hole 372 and the threaded hole 272, even if the fastener accidentally falls, it will not fall into the air outlet.

[0091] In some embodiments of the front shell assembly of the present invention, as Figure 3 and Fig.10 As shown, the first card slot structure 250 further includes a first anti-shrinkage groove 252 located at the rear side of the first insertion slot 251 and a first reinforcing rib 253 extending backward from the first anti-shrinkage groove 252 .
