[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0027] The microwave oven shell provided by the utility model can be disassembled and assembled by only moving the cover body 4 in a direction away from the front panel 2 or toward the front panel 2, without disassembling and assembling the fasteners on the microwave oven shell, which can effectively simplify the process of disassembling and repairing the microwave oven, and ensure the installation stability of the microwave oven shell on the microwave oven after multiple disassemblies and assemblies, thereby ensuring the safe use of the microwave oven.

[0028] In one embodiment of the present invention, Figures 1 to 6 As shown, the microwave oven housing includes a bottom plate 1, a front panel 2, a rear panel 3 and a cover body 4. The cover body 4 is formed with a top plate 41 and two side panels 42, and the top plate 41 is located between the two side panels 42. One of the front panel 2 and the side panels 42 is formed with at least one card plate 51, and the card plate 51 extends along a predetermined direction, wherein the predetermined direction is from the front panel 2 toward the rear panel 3. The other of the front panel 2 and the side panel 42 is formed with at least one card slot 52, and the card plate 51 is suitable for plugging with the card slot 52, and the card slot 52 is made of elastic material, and the card plate 51 and the card slot 52 are interference fit.

[0029] The microwave oven housing provided by the utility model connects the cover body 4 and the front panel 2 by plugging the card plate 51 into the card slot 52. When the microwave oven needs to be disassembled for maintenance, the cover body 4 only needs to be moved away from the front panel 2 and the card plate 51 needs to be removed from the card slot 52, so that the cover body 4 can be removed from the front panel 2. After the maintenance is completed, the cover body 4 only needs to be moved toward the front panel 2 and the card slot 52 and the card plate 51 need to be plugged and connected, so that the cover body 4 can be installed in the front panel 2.

[0030] During the insertion of the card plate 51 into the card slot 52, the card slot 52 undergoes elastic deformation to improve the convenience of reinstalling the cover body 4 back to the front panel 2. When the card plate 51 is fully inserted into the card slot 52, the front panel 2 and the cover body 4 are connected by the interference fit between the card plate 51 and the card slot 52, and the cover body 4 and the front panel 2 are tightly connected, so that when subjected to external force, the cover body 4 and the front panel 2 will not move relative to each other, thereby ensuring the installation stability between the front panel 2 and the cover body 4 after reinstallation.

[0031] Therefore, the microwave oven shell provided by the utility model is connected to the side panel 42 and the front panel 2 through the cooperation of the clamping plate 51 and the clamping groove 52. When disassembling and assembling the shell, it is only necessary to move the cover body 4 in the direction away from the front panel 2 or toward the front panel 2. There is no need to disassemble and assemble the fasteners on the microwave oven shell, which can effectively simplify the process of disassembling and repairing the microwave oven, and ensure the installation stability of the microwave oven shell on the microwave oven after multiple disassemblies and assemblies, thereby ensuring the safe use of the microwave oven.

[0032] It should be noted here that Figure 4 As shown, the front panel 2 and the rear panel 3 are both vertically mounted on the bottom plate 1, and the moving direction of the cover body 4 from the front panel 2 to the rear panel 3 (i.e. Figure 4 from left to right in the middle) or from the rear panel 3 to the front panel 2 (i.e. Figure 4 After the cover body 4 is connected to the front panel 2 through the card slot 52 and the card plate 51, the front panel 2, the rear panel 3, the top plate 41 and the two side plates 42 form an installation space for the internal structural parts and electrical components of the microwave oven to protect the internal structural parts and electrical components of the microwave oven.

[0033] In the embodiment of the present utility model, Figure 4As shown, the card plate 51 is formed at the edge of the front panel 2, and the card plate 51 extends along the length direction of the corresponding edge; the card slot 52 is formed on the inner wall surface of the cover body 4, and the opening of the card slot 52 faces the front panel 2, and the length of the card slot 52 is equal to the length of the corresponding card plate 51. Then, when the card plate 51 is inserted into the card slot 52, a connection structure arranged along the length direction of the card plate 51 is formed between the front panel 2 and the side panel 42, which increases the contact area when the front panel 2 and the side panel 42 are connected, thereby ensuring a stable connection between the front panel 2 and the cover body 4.

[0034] Specifically, the position where the card plate 51 is formed on the front panel 2 and the position where the card slot 52 is formed on the cover body 4 can be connected in the following manner:

[0035] In the first connection method, a card plate 51 is formed on the edge of the front panel 2 facing the side panel 42, and a card groove 52 is formed on the inner wall surface of the two side panels 42 to utilize the two side panels 42 to be snap-connected with the front panel 2 to complete the connection and fixation of the cover body 4 and the front panel 2.

[0036] The second connection method is that the card plate 51 is formed on the edge of the front panel 2 facing the top panel 41, and a card groove 52 is formed on the inner wall surface of the top panel 41 to utilize the snap connection between the top panel 41 and the front panel 2 to complete the connection and fixation between the cover body 4 and the front panel 2.

[0037] The third connection method is that a clamping plate 51 is formed on the edge of the front panel 2 facing the side panel 42 and the edge of the front panel 2 facing the top panel 41, and a clamping groove 52 is formed on the inner wall surface of the top panel 41 and the inner wall surfaces of the two side panels 42. The top panel 41 and the side panels 42 are simultaneously snap-connected with the front panel 2 to complete the connection and fixation of the cover body 4 and the front panel 2.

[0038] In this embodiment, since the connection strength of the snap connection is lower than that of the threaded connection, in order to ensure the connection strength between the cover body plate and the front panel 2, the connection method between the front panel 2 and the cover body 4 is preferably the third connection method, so that the cover body 4 and the front panel 2 form long connection structures at the top and side positions, ensuring that the key connection positions between the cover body 4 and the front panel 2 can form a stable connection, further ensuring the connection stability between the cover body 4 and the front panel 2.

[0039] In the embodiment of the present utility model, Figure 5 and Figure 6As shown, the card plate 51 is formed with a protrusion 511, and the protrusion 511 is arranged along the length direction of the card plate 51. The card slot 52 is formed with a limiting portion 521, and the protrusion 511 abuts against the limiting portion 521, and the protrusion 511 and the limiting portion 521 are interference-fitted. Then, when the card plate 51 is inserted into the card slot 52, the protrusion 511 abuts against the limiting portion 521, and the protrusion 511 and the limiting portion 521 are interference-fitted, so that the surface of the protrusion 511 is in close contact with the surface of the limiting portion 521, ensuring the close connection between the cover body 4 and the front panel 2, and then ensuring the installation stability between the front panel 2 and the cover body 4.

[0040] Among them, the protrusion 511 is preferably an arc boss formed on the clamping plate 51, so that when the protrusion 511 contacts the limiting portion 521, an arc transition can be formed between the protrusion 511 and the limiting portion 521, thereby reducing the wear between the protrusion 511 and the limiting portion 521 and extending the service life of the protrusion 511 and the limiting portion 521.

[0041] Of course, the protrusion 511 is not limited to an arc boss, and may also be a cylindrical boss or a protrusion 511 structure of other shapes. The shape of the protrusion 511 can be set according to actual needs.

[0042] On the other hand, the side of the card plate 51 facing the limiting portion 521 can also be directly set as a convex arc side surface to simplify the molding process of the card plate 51. The arc side surface of the card plate 51 cooperates with the limiting portion 521 to ensure a tight connection between the side panel 42 and the front panel 2.

[0043] It should be noted here that the protrusion 511 is formed in a strip shape on the card board 51, and the protrusion 511 extends along the length direction of the card board 51; or the card board 51 is formed with multiple protrusions 511, and the multiple protrusions 511 are arranged at intervals along the length direction of the card board 51.

[0044] Specifically, Figure 5 and Figure 6 As shown, the slot 52 is formed with two oppositely arranged slot sides 522, and at least one of the slot sides 522 is bent inward so that the relative distance between the two slot sides 522 gradually decreases along the opening direction of the slot 52, and a limiting portion 521 is formed at the position of the minimum relative distance between the two slot sides 522, and the minimum relative distance between the two slot sides 522 is less than the thickness of the protrusion 511 and the card plate 51, so as to achieve an interference fit between the limiting portion 521 and the protrusion 511, thereby ensuring a tight connection between the cover body 4 and the front panel 2.

[0045] In order to ensure that the relative distance between the two slot side surfaces 522 of the slot 52 gradually decreases along the opening direction of the slot 52, as shown in FIG. Figure 6As shown, the slot side surface 522 connected to the side plate 42 or the card plate 51 is set straight, and the other slot side surface 522 away from the side plate 42 or the card plate 51 is bent inward, so that the position where the relative distance between the two slot side surfaces 522 is the smallest forms a limit portion 521. Of course, the slot side surface 522 connected to the side plate 42 or the card plate 51 can also be set to bend inward, and the other slot side surface 522 can be set straight, or both slot side surfaces 522 can be set to bend inward. The shape setting of the two slot side surfaces 522 can be determined according to the actual connection strength between the side plate 42 and the front panel 2.

[0046] Furthermore, if Figure 6 As shown, a seesaw 523 is formed at the tail of at least one of the slot side surfaces 522, and the seesaw 523 extends in the direction of the opening of the slot 52, and the relative distance between the seesaw 523 and another slot side surface 522 gradually increases in the direction of the opening of the slot 52. Then, the card board 51 can be inserted into the slot 52 through the space between the seesaw 523 and the slot side surface 522, and the slot 52 is elastically deformed under the action of the protrusion 511, so that the card board 51 is inserted into the slot 52, and the connection between the cover body 4 and the front panel 2 is completed.

[0047] In the embodiment of the present utility model, Figure 2 As shown, a limiting convex plate 43 is formed on the side of the cover body 4 facing away from the front panel 2, and the rear panel 3 is located between the limiting convex plate 43 and the front panel 2 to ensure that the rear panel 3 will not interfere with the movement of the cover body 4 when the cover body 4 and the front panel 2 are disassembled.

[0048] One of the limiting convex plate 43 and the rear panel 3 is formed with a snap-fitting boss, and the other of the limiting convex plate 43 and the rear panel 3 is formed with a snap-fitting hole 53, and the snap-fitting boss is suitable for being inserted into the snap-fitting hole 53. Specifically, in this embodiment, the snap-fitting boss is formed on the rear panel 3, and the snap-fitting hole 53 is formed on the limiting convex plate 43. When the cover body 4 is reinstalled on the front panel 2, the cover body 4 is connected to the rear panel 3 through the snap-fitting hole 53, so as to ensure the overall stability of the microwave oven shell and protect the internal structural parts and electrical components of the microwave oven.

[0049] In an embodiment of the utility model, the top plate 41 and the two side plates 42 are integrally formed so that the top plate 41 and the two side plates 42 form one component, thereby reducing the number of parts of the microwave oven housing. When the cover body 4 is removed from the microwave oven or the cover body 4 is reinstalled into the microwave oven, the cover body 4 can be disassembled and assembled by simply sliding the top plate 41 and the two side plates 42 in the vertical direction, thereby simplifying the disassembly and assembly process when removing the cover body 4 from the microwave oven or reinstalling the cover body 4 into the microwave oven, thereby further improving the efficiency of disassembly and assembly of the cover body 4.

[0050] In another embodiment of the present invention, in order to facilitate the relative movement between the cover body 4 and the front panel 2, as shown in FIG. Figure 4 As shown, a guide plate 11 is formed at the edge of the bottom plate 1 facing the side plate 42, and the guide plate 11 is vertically arranged on the bottom plate 1, and the inner wall surface of the cover body 4 abuts against the guide plate 11. Then, when the cover body 4 is removed from the front panel 2 or the cover body 4 is reinstalled on the front panel 2, the guide plate 11 can be used to guide the cover body 4 to ensure that the cover body 4 does not swing when moving, and to prevent the cover body 4 from contacting the internal structural parts and electrical components of the microwave oven, thereby causing the internal structural parts and electrical components to be damaged by collision.

[0051] Furthermore, the guide plate 11 is flush with the card plate 51, so that the guide plate 11 can be used to ensure that the moving direction of the cover body 4 remains unchanged, so that the openings of the card plate 51 and the card slot 52 are always maintained in the same vertical plane, and then when the cover body 4 is reinstalled on the front panel 2, there is no need to realign the card plate 51 and the card slot 52 openings, thereby simplifying the operating process when the cover body 4 is reinstalled, reducing assembly errors, and improving assembly efficiency.

[0052] The utility model also provides a microwave oven, comprising an electrical component and a microwave oven housing as described in any one of the above embodiments. The electrical component is fixedly installed between the bottom plate 1, the front panel 2 and the rear panel 3, and the cover body 4 is covered on the electrical component through a card slot 52 and a card plate 51. The microwave oven has all the beneficial effects of the above microwave oven housing, which will not be repeated here.

[0053] It should be noted here that the electrical components include but are not limited to microwave generators, steam generators, temperature controllers and motors, etc. The structures and working principles of the above components are already existing technologies and will not be repeated here.

[0054] The above is a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present utility model.
