[0074] As another embodiment, the first positioning portion 101 is configured as a plug-in piece, and the second positioning portion 202 is configured as a plug-in interface corresponding to the plug-in piece.

[0075] Furthermore, this embodiment does not limit the specific structural form of a set of fastening connection structures formed by the first connection portion 102 and the second connection portion 203 .

[0076] As an embodiment, the first connection portion 102 and the second connection portion 203 are respectively configured as threaded connection columns, and are fastened and connected by bolts or screws.

[0077] As another embodiment, the first connection portion 102 is configured as a card slot, and the second connection portion 203 is configured as a buckle corresponding to the card slot, and the card slot and the buckle are fastened together by snapping together.

[0078] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 As shown, as a preferred embodiment, the first positioning portion 101 includes an inserting port 1011 , and the second positioning portion 202 includes an inserting piece 2021 ; when the cover plate 2 is assembled to the housing 1 , the inserting piece 2021 is adapted to be embedded in the inserting port 1011 .

[0079] In the above embodiment, the quick positioning and assembly between the cover 2 and the shell 1 is achieved through the plug-in positioning and matching structure of the plug-in piece 2021 and the plug-in interface 1011, and the cover 2 can also be limited to facilitate the subsequent fastening connection of the first connecting part 102 and the second connecting part 203.

[0080] Specifically, if Figure 1 、 Figure 2 、 Figure 3As shown, the opening direction of the plug port 1011 is a horizontal opening parallel to the bottom plate of the housing 1 , and the setting direction of the plug-in sheet 2021 is a horizontal thin sheet structure parallel to the main body 201 of the cover plate 2 .

[0081] Furthermore, if Figure 1 、 Figure 4 、 Figure 6 As shown, in this embodiment, two plug-in ports 1011 and two plug-in plates 2021 are provided respectively, forming two sets of plug-in positioning matching structures.

[0082] Furthermore, this embodiment does not limit the molding method of the plug interface 1011.

[0083] As an embodiment, a transverse through hole is directly opened on the side wall of the housing 1 to form a transversely arranged plug-in port 1011 .

[0084] As another embodiment, two protrusions are spaced apart along the height direction of the side wall of the housing 1 , and an insertion port 1011 is formed between the two protrusions.

[0085] In some embodiments, as Figure 4 、 Figure 5 As shown, as a preferred embodiment, the first positioning portion 101 also includes a first protrusion 1012 and a second protrusion 1013 located below the first protrusion 1012 , the first protrusion 1012 and the second protrusion 1013 are arranged at intervals, and the gap between the first protrusion 1012 and the second protrusion 1013 forms an insertion interface 1011 .

[0086] In the above embodiment, the plug interface 1011 is formed by the first protrusion 1012 and the second protrusion 1013 provided on the side wall of the shell 1, thereby avoiding directly opening a hole in the side wall of the shell 1 and improving the overall aesthetics of the shell assembly and the household appliance.

[0087] Specifically, if Figure 4 As shown, there are two first positioning portions 101, which are located at the same height on the side wall of the housing 1 to ensure that the cover plate 2 is in a horizontal state after installation. Each first positioning portion 101 is provided with a first protrusion 1012 and a second protrusion 1013.

[0088] Furthermore, if Figure 5 As shown, support ribs are respectively provided on the peripheries of the first protrusion 1012 and the second protrusion 1013 to ensure the support stability of the first protrusion 1012 and the second protrusion 1013, thereby ensuring the overall structural strength of the shell assembly.

[0089] In some embodiments, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, a first inclined surface 10121 is provided on a side of the first protrusion 1012 close to the plug interface 1011, and the first inclined surface 10121 is arranged toward the plug interface 1011; a second inclined surface 10131 is provided on a side of the second protrusion 1013 close to the plug interface 1011, and the second inclined surface 10131 is arranged toward the plug interface 1011.
