[0037] It is understandable that the shell body 100 can be enclosed by sheet metal materials, or can be stamped and bent by sheet metal materials. Specifically, the shell body 100 can be a cuboid, a cylinder or other special shapes, which is not specifically limited in the present invention.

[0038] It is understandable that the rear edge of the shell body 100 can be provided with a first clamping structure 300. The number of the first clamping structures 300 can be one or more, such as two, three, four or more, which is not specifically limited by the present invention.

[0039] In some embodiments of the present invention, Figure 5 、 6 As shown, the first clamping component 310 is a clamping slot opened on the rear side of the shell body 100, and the second clamping component 320 is a clamping hook arranged on the inner wall of the back plate 200 facing the shell body 100. When the back plate 200 is installed on the rear side of the shell body 100, the clamping hook is correspondingly clamped in the clamping slot.

[0040] By adopting the above structure, the hook is set on the inner wall of the back plate 200 facing the shell body 100, and the slot is set on the rear side of the shell body 100. When the back plate 200 is installed on the rear side of the shell body 100, the corresponding connection between the hook and the slot can limit the separation of the shell body 100 and the back plate 200. At the same time, the structure of the hook and the slot is simple, which can reduce the processing difficulty and reduce the production cost. The connection method between the hook and the slot is simple and quick, which is convenient for the installer to install and operate.

[0041] It can be understood that the card slot can be set on the edge of one side of the shell body 100 bent toward the accommodating cavity 110, or it can be set on other components and the component can be fixed to the rear side of the shell body through welding or other connection methods. Specifically, the card slot can be rectangular, triangular, prismatic or other special shapes, and the present invention does not make specific limitations on this.

[0042] It is understandable that there can be multiple hooks and slots, such as Figure 3 There are six card slots shown, and the number of card hooks and card slots can be more or less, which is not specifically limited in the present invention.

[0043] In some embodiments of the present invention, Figure 6 As shown, the hook is formed by punching one side edge of the back plate 200 .

[0044] By adopting the above structure, the hook formed by stamping can be more easily automated during the production process, which can make the production efficiency higher and reduce the production cost. At the same time, the size and shape accuracy of the hook formed by stamping can be better guaranteed.

[0045] In some embodiments of the present invention, Figure 4 As shown, the card slot includes an upper section 311 and a lower section 312 that are connected to each other, wherein the width of the lower section 312 is greater than the width of the upper section 311, and the width of the upper section 311 gradually decreases from bottom to top.

The latch 312 is provided on the top of the bracket 311 and the bottom of the bracket 312 is provided on the bottom of the bracket 311. The latch 312 is provided on the top of the bracket 311 and the bottom of the bracket 312 is provided on the bottom of the bracket 311.

[0047] It is understandable that the shapes of the edges on both sides of the upper section 311 can be curved, straight or other shapes, and the lower section 312 can be rectangular, triangular, prismatic or other special shapes, which are not specifically limited in the present invention.

[0048] In some embodiments of the present invention, Figure 5 、 6 As shown, at least one group of second clamping structures 400 is arranged between the back plate 200 and the upper rear part of the shell body 100, and the second clamping structure 400 includes a third clamping component 410 and a fourth clamping component 420 that can cooperate with each other to clamp, the third clamping component 410 is arranged on the inner wall of the back plate 200 facing the shell body 100, and the fourth clamping component 420 is arranged on the upper rear part of the shell body 100, wherein the back plate 200 can be clamped and connected to the upper rear part of the shell body 100 through the second clamping structure 400.

[0049] By adopting the above structure, when the back panel 200 is installed on the rear side of the shell body 100, the back panel 200 can be connected to the upper rear side of the shell body 100 through the second clamping structure 400, thereby preventing the upper part of the back panel 200 from warping outward. At the same time, the second clamping structure 400 can further make the connection between the back panel 200 and the shell body 100 more stable.

[0050] It is understandable that the second clamping structure 400 may be one or more, such as two, three, four or more, which is not specifically limited in the present invention.

[0051] In some embodiments of the present invention, Figure 6As shown, the third clamping component 410 is a buckle arranged on the inner wall of the back plate 200 facing the shell body 100, and the fourth clamping component 420 is a clamping portion arranged on the upper rear side of the shell body 100. When the back plate 200 is installed on the rear side of the shell body 100, the clamping portion is clamped to the buckle.

[0052] By adopting the above structure, when installing the back panel 200 and the rear side of the shell body 100, the clip is inserted into the slot and the back panel is pushed upward. The clip can be connected with the snap-in portion, thereby fixing the back panel 200 to the upper rear side of the shell body 100, thereby preventing the upper part of the back panel 200 from warping outward. At the same time, when the snap-in portion is inserted into the clip, the clip can play a positioning role so that the top edge of the back panel 200 is not easy to extend beyond the upper surface of the shell body 100.

[0053] It can be understood that there can be one, two, three or more buckles and snap-fitting parts. Specifically, the snap-fitting part can be a component that can snap-fit ​​with all buckles at the same time, or it can be multiple components that snap-fit ​​with the buckles separately. The present invention does not make specific limitations on this.

[0054] It is understandable that the snap-fit ​​portion can be formed by bending the edge of the upper rear portion of the shell body 100, or can be fixed to the upper rear portion of the shell body 100 by welding or other connection methods, and the present invention does not make specific limitations on this.

[0055] It is understandable that the connection between the buckle and the connecting portion may be an interference fit connection, a transition fit connection, or a clearance fit connection, and the present invention does not impose any specific limitation on this.

[0056] In some embodiments of the present invention, Figure 6 As shown, the buckle is formed by stamping one side edge of the back plate 200 .

[0057] By adopting the above structure, the buckle formed by stamping can be more easily automated during the production process, making the production efficiency higher and reducing the production cost. At the same time, the size and shape accuracy of the buckle can be better guaranteed.

[0058] In some embodiments of the present invention, Figure 7 、 8 As shown, at least one set of locking structures 500 is provided between the rear lower portion of the shell body 100 and the back plate 200 , and the back plate 200 is locked together with the shell body 100 through the locking structures 500 .

[0059] By adopting the above structure, after the back panel 200 is snap-connected to the shell body 100, the back panel 200 can be locked together with the shell body 100 through the locking structure 500, thereby preventing the back panel 200 from falling downward. At the same time, the locking structure 500 can make the connection between the back panel 200 and the shell body 100 more stable.

[0060] It is understandable that if Figure 7 As shown, the number of the locking structures 500 can be four, or the number of the locking structures 500 can be one, two, three or more, which is not specifically limited in the present invention.

[0061] In some embodiments of the present invention, Figure 8 As shown, the locking structure 500 includes a first connecting hole 510, a second connecting hole 520 and a locking member. The first connecting hole 510 is arranged at the bottom of the back plate 200, and the second connecting hole 520 is arranged at the lower rear side of the shell body 100. When the back plate 200 is installed on the rear side of the shell body 100, the first connecting hole 510 corresponds to the second connecting hole 520, and the locking member can be passed through the first connecting hole 510 and the second connecting hole 520 to lock the back plate 200 and the shell body 100 together.

[0062] By adopting the above structure, connecting holes are opened at the bottom of the back panel 200 and the lower rear part of the shell body 100. After the back panel 200 is snap-connected to the shell body 100, a locking member can be used to lock it to prevent the back panel 200 from falling downward. Even if a part of the locking member is exposed after locking, it will only be exposed at the bottom of the shell body 100, and will not affect the smoothness of the outer wall of the back panel 200. At the same time, the locking structure 500 can further make the connection between the back panel 200 and the shell body 100 more stable.

[0063] It can be understood that after the back panel 200 is snap-connected to the shell body 100, the first connection hole 510 can be more easily aligned with the second connection hole 520, and then the locking piece is used to penetrate the first connection hole 510 and the second connection hole 520, so that the locking can be completed more easily, and the installation process is simple and convenient.

[0064] like Figure 1 、 2 As shown, an electric oven according to an embodiment of the second aspect of the present utility model includes: an electric oven body, and the electric oven body is configured with a shell assembly of the electric oven as described in the above embodiment.

[0065] The electric oven of the embodiment of the present invention adopts the shell assembly of any of the above-mentioned embodiments, and the back panel 200 is detachably connected to the rear side of the shell body through the first clamping structure 300. Therefore, there is no need to open a through hole on the back panel, and there is no need to use screws to connect the shell body and the back panel. Compared with the connection method of the prior art in which screws are used to lock the back panel 200 to the rear side of the shell body 100, the clamping connection using the first clamping structure 300 can make the outer wall of the back panel 200 smoother and neater, and it is not easy to scratch the wall, table back panel or other components, and at the same time can make the electric oven more beautiful.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
