[0034] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, the present application first provides a turntable structure, including a bracket 10, a driving member 20, a first transmission assembly 30, a second transmission assembly 40, a rotating shaft 50 and a turntable 60, wherein the driving member 20 is fixed to the bracket 10, the rotating shaft 50 passes through the bracket 10, and the turntable 60 is fixed to the rotating shaft 50 and is used to carry food;

[0035] The first transmission assembly 30 and the second transmission assembly 40 respectively connect the driving member 20 with the rotating shaft 50, wherein the first transmission assembly 30 can drive the rotating shaft 50 to rotate around its own axis, and the second transmission assembly 40 can drive the rotating shaft 50 to translate along its own axis.

[0036] In the present application, the output shaft of the driving member 20 is connected to the rotating shaft 50 through the first transmission component 30 and the second transmission component 40 respectively, so that only relying on the driving member 20, the rotating shaft 50 can be driven to complete the two actions of rotation and lifting, so that the turntable 60 can be lifted and lowered in the vertical direction while rotating, ensuring that all parts of the food on the turntable 60 are heated evenly, effectively improving the baking and coloring uniformity of the food, and improving the baking efficiency and baking effect.

[0037] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the output shaft of the driving member 20 is arranged in the vertical direction, the rotating shaft 50 is parallel to the output shaft of the driving member 20, and the rotating shaft 50 is fixed with two limiting plates 51 at intervals along its own axial direction to form a limiting groove 52 between the two limiting plates 51;

[0038] The second transmission assembly 40 includes a first bevel gear 41, a second bevel gear 42 and a crank 43. The axis of the first bevel gear 41 is perpendicular to the second bevel gear 42. The first bevel gear 41 is fixed to the output shaft of the driving member 20. The second bevel gear 42 is rotatably connected to the bracket 10 and meshes with the first bevel gear 41. One end of the crank 43 is fixed to the second bevel gear 42, and the other end is inserted into the limiting groove 52.

[0039] The driving member 20 drives the second bevel gear 42 to rotate back and forth through the first bevel gear 41, thereby driving the crank 43 to swing or rotate. Since the other end of the crank 43 is located in the limit groove 52, and the rotating shaft 50 passes through the bracket 10 and cannot translate in the horizontal direction, the swinging or rotation of the crank 43 can drive the rotating shaft 50 to move back and forth in the vertical direction through the upper and lower limit plates 51, thereby driving the turntable 60 to rise and fall.

[0040] Specifically, the two limiting plates 51 are both circular, the crank 43 is U-shaped, one end of which is fixed to the center of the second bevel gear 42 , and the other end is inserted into the limiting groove 52 along the radial direction of the limiting plate 51 .

[0041] More specifically, the crank 43 abuts against two limit plates 51 in the vertical direction to avoid a virtual position in the process of the crank 43 driving the shaft 50 to rise and fall, thereby ensuring that the forward and reverse driving force of the driving member 20 can be instantly transmitted to the shaft 50.

[0042] It should be noted that, during the swinging process of the crank 43 , the projection of the crank 43 along the vertical direction is always partially located in the limiting groove 52 , so as to ensure that the crank 43 can always abut against the limiting plate 51 .

[0043] Of course, in some other embodiments, the output shaft of the driving member 20 can also be set in other directions, as long as it is ensured that the output shaft can drive the rotating shaft 50 to rise and fall in the vertical direction after being transmitted by the second transmission assembly 40, and can drive the rotating shaft 50 to rotate after being transmitted by the first transmission assembly 30.

[0044] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the first transmission assembly 30 includes a first gear 31 and a second gear 32, the first gear 31 is fixed to the output shaft of the driving member 20, and the second gear 32 is fixed to the rotating shaft 50, and the tooth width (dimension along the vertical direction) of one of the first gear 31 and the second gear 32 is greater than the other.

[0045] By setting the tooth width of one of the first gear 31 and the second gear 32 to be larger than the other, the first gear 31 and the second gear 32 can always be meshed during the lifting process of the rotating shaft 50, thereby ensuring that the rotating shaft 50 can still rotate during the lifting process.

[0046] Specifically, the tooth width of the second gear 32 is greater than that of the first gear 31 .

[0047] In some embodiments, the output shaft of the driving member 20 protrudes from itself along the upper and lower sides, and the first gear 31 and the first bevel gear 41 are respectively fixed to the output shaft on both sides.

[0048] Of course, in some other embodiments, the first transmission assembly 30 and the second transmission assembly 40 may also adopt other commonly used transmission structures, as long as both can drive the rotating shaft 50 to complete rotation and lifting respectively under the drive of the driving member 20, and the two movements do not interfere with each other. The present application gives different examples here.

[0049] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the bracket 10 includes an upper bracket plate 11 and a lower bracket plate 12 fixed to each other, and the driving member 20, the first transmission assembly 30 and the second transmission assembly 40 are all located between the upper bracket plate 11 and the lower bracket plate 12; the rotating shaft 50 passes through the upper bracket plate 11 and the lower bracket plate 12, and the rotating shaft 50 and the upper bracket plate 11 and the lower bracket plate 12 are all clearance fit.

[0050] The upper support plate 11 and the lower support plate 12 can provide a limiting function for the rotating shaft 50 to prevent it from translating or tipping over in the horizontal direction.

[0051] In addition, arranging the transmission components and the driving member 20 between the upper bracket plate 11 and the lower bracket plate 12 can also provide a certain degree of protection for the parts, and the integrated design also facilitates subsequent maintenance and repair.

[0052] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, a stopper 53 is fixed to the top of the rotating shaft 50 and can abut against the upper bracket plate 11 in the vertical direction. When the crank 43 escapes from the limiting groove 52, the stopper 53 can play an anti-falling effect. The stopper 53 abuts against the upper bracket plate 11 to prevent the rotating shaft 50 from falling as a whole and damaging the inner liner 100.

[0053] In some embodiments, a notch is provided on the edge of the stopper 53 to facilitate identification and installation.

[0054] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, the turntable 60 is detachably fixed to the rotating shaft 50, so that the user can remove the turntable or replace a different turntable 60 according to actual needs, so as to improve the versatility of the turntable structure of the present application.

[0055] Please combine Figure 2 as well as Figure 4As shown, in some embodiments, the turntable 60 includes a fixing portion 61, a plurality of connecting rods 62 and a disk body 63, wherein the projection of the fixing portion 61 along the vertical direction is located at the center of the disk body 63 and can be detachably fixed to the rotating shaft 50; both ends of the connecting rod 62 are respectively fixed to the fixing portion 61 and the disk body 63, wherein the angle formed by two adjacent connecting rods 62 with the fixing portion 61 as the vertex is greater than or equal to 180°, and the gap between the two connecting rods 62 is used as an opening for users to take and place food, and sufficient space is reserved for users to take and place food, so as to facilitate users to take and place food.

[0056] In some embodiments, the connecting rod 62 is L-shaped, the part connected to the fixing portion 61 is parallel to the plate body 63, and the part connected to the plate body 63 is perpendicular to the plate body 63, so as to form a relatively large accommodating space between the connecting rod 62 and the plate body 63, thereby minimizing the impact of the connecting rod 62 on the placement of food.

[0057] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, a clamping portion 54 is fixed to the bottom end of the rotating shaft 50, and a clamping groove 611 corresponding to the clamping portion 54 is formed in the fixing portion 61, and the clamping portion 54 is clamped with the inner wall of the clamping groove 611, so that the clamping portion 54 and the fixing portion 61 are abutted against each other in the vertical direction and fixed to each other in the circumferential direction; in this way, the up and down movement of the turntable 60 is limited by gravity, and the circumferential rotation of the turntable 60 is limited by the clamping portion 54, and under the premise of meeting the limit requirements of the turntable 60, disassembly and assembly are relatively convenient.

[0058] Specifically, the slot 611 includes a hexagonal slot and a shaft slot. The shaft slot is located on the upper side of the hexagonal slot and is connected to the hexagonal slot. The projection of the shaft slot along the vertical direction is located inside the hexagonal slot. The shaft slot and the hexagonal slot open to the same side in the horizontal direction. The connecting portion 54 can be connected to the corresponding hexagonal slot.

[0059] In addition, the opening area and path smoothness of the exhaust port of existing cooking equipment such as steam ovens are fixed, and the exhaust rate of the exhaust port cannot be changed according to the humidity changes in the inner pot, and thus the humidity in the inner pot cannot be adjusted autonomously. When the humidity in the pot is high in a short period of time, the moisture cannot be discharged quickly, which will affect the dehumidification performance and ultimately affect the baking effect.

[0060] In this regard, please combine Figure 1 , Figure 4 as well as Figure 5As shown, in some embodiments, the turntable structure also includes an inner tank 100, an exhaust air duct 200 and a humidity sensor. The exhaust air duct 200 is arranged at the top of the inner tank 100 and an air duct 210 is fixed inside. The top of the air duct 210 is provided with an exhaust port 211 connected to the exhaust air duct 200, and the bottom is connected to the interior of the inner tank 100; the driving member 20, the first transmission assembly 30 and the second transmission assembly 40 are all located at the top of the exhaust air duct 200, the rotating shaft 50 passes through the air duct 210 to the interior of the inner tank 100, and a wind shield 55 located in the air duct 210 is fixed on the rotating shaft 50; the turntable 60 and the humidity sensor are both located inside the inner tank 100, and the humidity sensor is electrically connected to the driving member 20.

[0061] It is not difficult to understand that in the present application, the closer the wind shield 55 is to the exhaust port 211, the greater the obstacle of the wind shield 55 to the exhaust and the lower the dehumidification rate. Conversely, the dehumidification rate is higher.

[0062] Therefore, in the present application, a humidity sensor is provided to detect the internal humidity of the inner tank 100 in real time, and the rotation range of the driving member 20 is controlled according to the real-time humidity value, so that the wind shield 55 is controlled to move within a certain range to control the dehumidification rate; for example, when the humidity is detected to be high, the wind shield 55 is controlled to move back and forth within a range away from the exhaust port 211, and the dehumidification rate is relatively high at this time. When the humidity is detected to be reduced, the movement range of the wind shield 55 is controlled to be adjusted upward to appropriately reduce the dehumidification rate, thereby realizing real-time autonomous adjustment of the exhaust efficiency and improving the dehumidification performance and baking effect.

[0063] A second aspect of the present application provides a cooking device, comprising the above-mentioned turntable structure.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
