To better illustrate the function of the door structure of the device provided in the embodiments of the present application, the following takes the application in a steam oven as an example for illustration.

[0051] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 , as shown in the figure, the present application provides a door structure of a device. The door structure includes: a knob assembly 3 and a first door assembly 1. The knob assembly 3 includes a knob cover 31, a knob 33, and a knob base 32 that are connected in sequence. The first door assembly 1 includes a first door body 11, a push-pull member 12, and a driving member 13. The knob 33 is rotatably connected to the knob base 32 and the knob cover 31. The knob assembly 3 is fixedly connected to the first door body 11. The knob 33 is rotatably connected to the driving member 13.

[0052] The push-pull member 12 includes a first locking portion 121 and a sliding end 122. The driving member 13 is provided with a sliding groove 132. The first locking portion 121 is slidably disposed in a slideway 1112 of the first door assembly 1. The sliding end 122 is slidably disposed in the sliding groove 132. The door structure further includes a second locking portion 4 provided on the device. The structure of the first locking portion 121 matches the structure of the second locking portion 4.

[0053] Exemplarily, the driving member 13 can be a swing shaft, and the sliding groove 132 is provided on the swing shaft. Optionally, the number of sliding grooves 132 can be 2, which is convenient for manufacturing and installation without the need to distinguish the installation direction.

[0054] Optionally, the slideway 1112 includes an upper wall of the slideway 1112 and a lower wall of the slideway 1112. The upper wall of the slideway 1112 and the lower wall of the slideway 1112 form a stepped structure. The first locking portion 121 is disposed between the upper wall of the slideway 1112 and the lower wall of the slideway 1112. A connection surface connecting the upper wall of the slideway 1112 and the lower wall of the slideway 1112 forms a limit with the first locking portion 121.

[0055] In the embodiment of the present application, by installing a knob assembly and a push-pull member on the first door body, the knob assembly can drive the push-pull member to move. A second locking portion is installed on the device, so that the first locking portion of the push-pull member can be locked or separated from the second locking portion, thereby realizing physical control of the locking and unlocking of the door structure and the device, avoiding uncontrollable influence of changes in the power-on situation of the device on the locked state, and enhancing the reliability and stability of the door unlocking and locking control.

[0056] Please continue to refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 , Figure 5 、 Figure 6 、 Figure 7 which shows the assembly relationship of the knob assembly, where Figure 6 is a schematic diagram of the assembly relationship formed based on the B-B cross-section of Figure 5 . As shown in the figure, in some possible embodiments, a first guiding groove 312 is provided on a side of the knob cover 31 close to the knob base 32, and a second guiding groove 323 is provided on a side of the knob base 32 close to the knob cover 31. The first guiding groove 312 and the second guiding groove 323 form a guiding port. A slider 332 is fixedly provided on an inner ring of the knob 33, and the slider 332 is slidably disposed in the guiding port.

[0057] Optionally, the first guiding groove 312 and the second guiding groove 323 can be semi-circular arcs. The guiding port formed by the first guiding groove 312 and the second guiding groove 323 is the track for the movement of the slider 332. One end of the slider 332 is fixedly connected to the inner ring of the knob 33, and the movement track of the knob 33 is indirectly set by setting the movement track of the slider 332.

[0058] Please continue to refer to Figure 2 , in some possible embodiments, a knob limiting structure 334 is provided on the knob 33, and the slider 332 and the knob limiting structure 334 are centrosymmetric with respect to the geometric center of the knob 33.

[0059] In the embodiment of the present application, by separately arranging the knob limiting hole and the slider on both sides of the geometric center of the knob, a guiding track is formed on both sides of the geometric center of the knob, which can improve the stability of the knob movement guiding.

[0060] Please continue to refer toFigure 2 , as Figure 2 shown, a knob limiting hole 335 is provided on the knob 33, and the knob limiting hole 335 is used to accommodate the knob limiting structure 334. Exemplarily, the knob limiting structure 334 can be a pin.

[0061] Further, to fix the knob limiting structure 334, a knob outer ring 33 is sleeved outside the knob 33, so that the knob limiting structure 334 and the knob 33 can move integrally. When the knob 33 is rotated, the knob limiting structure 334 can be driven to rotate synchronously.

[0062] In the embodiment of the present application, by providing a knob outer ring outside the knob, the knob limiting structure is fixed in the knob limiting hole, so that the movement state of the knob limiting structure is consistent with the movement state of the knob, which is beneficial to maintaining the stability of the movement track of the knob through the knob limiting structure.

[0063] Please continue to refer to Figure 2 , as Figure 2 shown, in some possible embodiments, a third guiding groove 324 is provided on the knob base 32, and the knob limiting structure 334 is slidably connected to the third guiding groove 324.

[0064] Further, the knob limiting structure 334 is provided to ensure that the knob 33 rotates along a preset track. The knob limiting structure 334 is slidably connected to the third guiding groove 324 to form a guiding track. It should be noted that the slider 332 is arranged in the guiding opening formed by the relative arrangement of the foregoing first guiding groove 312 and the second guiding groove 323, and the knob limiting structure 334 opposite to the slider 332 is arranged in the third guiding groove 324, thereby forming a double guiding structure.

[0065] In this embodiment, by respectively arranging the slider on the knob and the knob limiting structure in two guiding tracks, it is ensured that the knob will not be displaced during rotation and can rotate along a preset track, thereby improving the position accuracy of the knob rotation. By controlling the rotation angle of the knob, unlocking and locking can be accurately controlled, and the reliability of the unlocking and locking operations is improved.

[0066] Please continue to refer to Figure 2 , Figure 3 , Figure 4 , as shown in the figure, in some possible embodiments, a guiding column 311 is provided on the side of the knob cover 31 close to the knob 33, a guiding hole 321 is provided on the knob base 32, the knob assembly 3 further includes a fixing base 34, and a guiding groove 343 is provided on the fixing base 34. The guiding column 311 is sequentially sleeved with the knob base 32 and the fixing base 34 through the guiding hole 321 and the guiding groove 343.

[0067] Optionally, the knob 33 is used to rotationally control the movement of the push-pull member 12. The knob cover 31 and the knob base 32 are used to guide the knob 33 to rotate along a preset track. The knob cover 31, the knob base 32, and the fixed seat 34 are fixedly connected through the guide posts 311. During the process of rotating the knob 33, the knob cover 31, the knob base 32, and the fixed seat 34 all remain stationary. Exemplarily, when the knob 33 is rotated clockwise, the push-pull member 12 moves towards the bottom of the first door body 11, and the first locking portion 121 moves downward accordingly and locks with the second locking portion 4. When the knob 33 is rotated counterclockwise, the push-pull member 12 moves towards the top of the first door body 11, and the first locking portion 121 moves upward accordingly and separates from the second locking portion 4, thereby achieving unlocking. Those skilled in the art can understand that the above is only an exemplary illustration, and the movement direction can also be set such that when the knob 33 is rotated clockwise, the push-pull member 12 moves towards the top of the first door body 11.

[0068] Optionally, the number of the guide grooves 343 is adapted to the number of the guide posts 311. Exemplarily, the number can be 2. For the consideration of structural stability, it can also be set to 3, 4, etc.

[0069] In the embodiment of the present application, by providing guide posts on the knob cover and providing guide holes and guide grooves at corresponding positions on the knob base and the fixed seat, the knob can be fixedly arranged between the knob base and the knob cover in a preset manner, ensuring that the slider of the knob and the knob limiting structure are respectively slidably arranged in the guide opening and the third guide groove, thereby ensuring the smoothness and stability of the rotation of the knob.

[0070] Please continue to refer to Figure 3 、 Figure 5 、 Figure 7 and Figure 12 , in some possible embodiments, a first limiting structure 322 is provided on the knob base 32, a second limiting structure 342 is provided on the fixed seat 34, and the shape of the first limiting structure 322 matches the shape of the second limiting structure 342.

[0071] As Figure 5 shown, a sliding shaft 341 is provided on one side of the fixed seat 34 for connecting with the first limiting groove 123 of the push-pull member 12. As Figure 3 shown, a second limiting structure 342 is provided on the other side of the fixed seat 34 for clamping with the knob base 32. Figure 7 is an assembly schematic diagram of the A-A cross-section based on Figure 5 and is shown with a partial enlargement. As Figure 7As shown in the enlarged partial view, the first limiting structure and the second limiting structure are snap-connected. It can be seen that the knob base 32 and the fixed base 34 are fixed at three points. The three points are the fixed structure formed by the snap connection of two guiding columns 311, the first limiting structure 322 and the second limiting structure 342, which can improve the fixing stability between the knob base 32 and the fixed base 34, and thus improve the overall structural stability of the knob assembly 3.

[0072] In the embodiment of the present application, by respectively arranging limiting structures on the fixed base and the knob base, the number of fixed points between the knob base and the fixed base is increased, and the structural stability of the fixation between the fixed base and the knob base is improved.

[0073] Please continue to refer to Figure 8 , in some possible embodiments, the push-pull member 12 is further provided with a first limiting groove 123, and the fixed base 34 is further provided with a sliding shaft 341, and the sliding shaft 341 is slidably arranged in the first limiting groove 123.

[0074] Optionally, the fixed base 34 is fixedly connected to the first door body 11. The sliding shaft 341 on the fixed base 34 is slidably connected to the first limiting groove 123. When the driving member 13 drives the sliding end 122 of the push-pull member 12 to move through the sliding groove 132, the push-pull rod can move along the track defined by the shape of the first limiting groove 123 without deviation, so as to ensure the concentricity of the connection between the knob 33 and the driving member 13.

[0075] Please refer to Figure 9 、 Figure 10 , as shown in the figure, in some possible embodiments, the driving member 13 is provided with a convex structure 131, and the knob 33 is provided with a transmission limiting structure 331, and the convex structure 131 matches the transmission limiting structure 331.

[0076] It should be noted that the transmission limiting structure 331 is used to connect the driving member 13 and the knob 33 to achieve transmission. Since the sliding end 122 of the push-pull member 12 is arranged in the sliding groove 132 of the driving member 13, when the knob 33 is rotated, the driving member 13 is driven to rotate through the transmission limiting structure 331, and then the sliding end 122 of the push-pull member 12 is driven to move through the sliding groove 132 of the driving member 13. Thus, the unlocking and locking of the first locking portion 121 of the push-pull member 12 and the second locking portion 4 provided on the device can be controlled by controlling the rotation of the knob 33.

[0077] Exemplarily, a boss is provided on the driving member 13, and a protruding structure 131 is provided on the boss. The protruding structure 131 and the transmission limiting structure 331 can be relatively fixed by means of plugging, sleeving, etc. In some possible embodiments, the protruding structure 131 can be a limiting shaft, a limiting convex block and other structures. Optionally, the transmission structure between the driving member 13 and the knob 33 can be a shaft pin 3323 structure, etc.

[0078] In the embodiment of the present application, by providing a protruding structure on the driving member and a transmission limiting structure on the knob, the protruding structure is connected to the transmission limiting structure, thereby establishing a transmission relationship between the knob and the push-pull member. By rotating the knob, the movement of the push-pull member in a specific direction is controlled to change the positional relationship between the first locking portion and the second locking portion, thereby changing the locking state of the door structure of the device and overcoming the influence of the change in the energized state on the locking relationship.
