Specifically, the guide structure includes a vertical slide groove 125 provided on the inner shell 12, and a slider provided between the lifting seat 52 and the tray 2, and the slider is slidably matched with the vertical slide groove 125. The outer shell 11 includes an upper cover outer shell 11 and a box outer shell 11, and the inner shell 12 includes a box inner shell 12 and an upper cover inner shell 12. The upper cover inner shell 12 and the upper cover outer shell 11 are connected to form a box cover 101 of the frying device, and the box outer shell 11 and the box inner shell 12 are connected to form a box body 102 of the frying device.

[0028] An axle frame 51 is arranged between the inner shell 12 and the outer shell 11, and the transmission mechanism includes a lifting seat 52 fixed to the tray 2 and located between the inner shell 12 and the outer shell 11, a rotating shaft 53 rotatably installed on the axle frame 51, and a crank 54 sleeved on the rotating shaft 53 and capable of rotating with the rotating shaft 53. The knob 4 is connected to the rotating shaft 53 so that when the knob 4 rotates, the crank 54 can be driven to rotate. A power transmission structure is arranged between the crank 54 and the lifting seat 52, which can drive the lifting seat 52 to move up and down when the crank 54 rotates.

[0029] In the above scheme, by turning the knob 4, the crank 54 can be driven to rotate, thereby driving the lifting seat 52 and the tray 2 to move up and down together. According to needs, during the process of baking food by the baking device, manual or electric adjustment methods can be used to adjust the tray 2 to a suitable height in real time.

[0030] In one embodiment, the power transmission structure includes a slide groove 541 disposed on the crank 54 and a sliding shaft 521 disposed on the lifting seat 52 . The sliding shaft 521 is embedded in the slide groove 541 and slidably cooperates with the slide groove 541 .

[0031] Furthermore, an elastic lock capable of automatically locking the rotating shaft 53 and the shaft frame 51 is provided on the shaft frame 51 , and an unlocking member 55 capable of pushing the elastic lock to unlock the rotating shaft 53 and the shaft frame 51 is provided on the knob 4 .

[0032] Preferably, the shaft frame 51 includes a vertical plate 511 located on the right side of the crank 54, the elastic lock includes a movable locking ring 56 sleeved on the rotating shaft 53, and an elastic member 57 capable of pushing the movable locking ring 56 to move leftward relative to the vertical plate 511, the left end of the rotating shaft 53 is fixed with a pressure cover 58 located on the left part of the crank 54, the pressure cover 58 is provided with a first locking hole 581 and a limiting groove 582, the vertical plate 511 is provided with a second locking hole 512 directly opposite to the first locking hole 581 and a limiting groove 582 2, the movable lock ring 56 is provided with a short rod 561 that passes through the first lock hole 581 and the second lock hole 512 to lock the rotating shaft 53 and the shaft frame 51, and the movable lock ring 56 is also provided with a long rod 562 that passes through the third lock hole 513 and the limiting groove 582. The limiting groove 582 leaves a space for the long rod 562 to move relative to it, and the crank 54 is provided with an avoidance groove 542 that can avoid the short rod 561 and an avoidance groove 542 that can avoid the long rod 562. The unlocking member 55 is sleeved in the knob 4 and can move left and right relative to it. When the unlocking member 55 is pressed, the unlocking member 55 moves to the right and pushes the long rod 562 to make the short rod 561 withdraw from the first lock hole 581, and the rotating shaft 53 and the shaft frame 51 are unlocked. In order to prevent the unlocking member 55 from being misaligned with the long rod 562 , a pressure ring for transmitting power may be provided between the unlocking member 55 and the long rod 562 .

[0033] In the above scheme, the method for adjusting the height of the tray 2 is: first press the unlocking member 55, at which time the unlocking member 55 will push the movable locking ring 56 to the right, so that the short rod 561 on the movable locking ring 56 will withdraw from the first locking hole 581, and the rotating shaft 53 and the shaft frame 51 will be unlocked; then the knob 4 can be turned to drive the rotating shaft 53 and the crank 54 to rotate together. While the crank 54 rotates, the lifting seat 52 and the tray 2 can be driven to move up and down together. After adjusting to the right position, release the unlocking member 55, and under the elastic force of the compression spring, the short rod 561 will be inserted into the corresponding first locking hole 581, locking the rotating shaft 53 and the shaft frame 51. At this time, the crank 54 cannot rotate either, and the tray 2 can be maintained at this height position.

[0034] Preferably, a retaining spring 59 is provided on the rotating shaft 53, and the elastic member 57 is a compression spring sleeved on the rotating shaft 53, and two ends of the retaining spring 59 and the movable locking ring 56 are respectively in contact with two ends of the compression spring.

[0035] In order to balance the force on the tray 2 , a lifting seat 52 is required to be provided on the left and right parts of the tray 2 , and cranks 54 are provided at both ends of the rotating shaft 53 , and the two lifting seats 52 are driven to rise and fall synchronously through the two cranks 54 .

[0036] Furthermore, an elastic tension member capable of applying an upward pulling force to the lifting seat 52 is provided between the lifting seat 52 and the inner shell 12. Preferably, the elastic tension member comprises two tension springs 6. The provision of the elastic tension member can provide assistance when the tray 2 rises upward, so that the user can easily turn the knob 4.

[0037] In some embodiments of the present invention, the transmission mechanism may also adopt other structural forms, for example, the crank 54 on the rotating shaft 53 is replaced by a gear, and a rack meshing with the gear is provided on the lifting seat 52, and such a structure is used to drive the lifting seat 52 and the tray 2 to move up and down. Alternatively, a connecting rod is used as the power transmission structure, so that the crank 54, the connecting rod, the lifting seat 52 and the inner shell 12 constitute a crank 54 slider mechanism, thereby driving the lifting seat 52 and the tray 2 to move up and down.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
