[0041] Among them, the height direction of the inner container 1 is defined as the Z-axis direction shown in the figure, and the two side walls 11 of the inner container 1 are respectively adjacent to the two sides of the opening of the inner container 1, so as to facilitate taking or placing the steaming and baking tray 5 through the opening of the inner container 1.

[0042] The cooking equipment provided by the embodiment of the utility model places the steaming and baking tray 5 on the four supporting pieces 22, and the user can control the four lifting assemblies 2 to drive the corresponding lifting pieces 21 to lift to a unified height position at the same time according to the types and sizes of the cooking materials, so as to adjust the height position of the steaming and baking tray 5, or the user can also control the four lifting assemblies 2 to drive the corresponding lifting pieces 21 to lift to different height positions independently according to the shapes or coloring requirements of the cooking materials, so as to adjust the placing angle of the steaming and baking tray 5, such as forward, backward, left or right inclination and the like, so that the height position and the placing angle of the steaming and baking tray 5 can meet different cooking materials, and the cooking effect is improved; during the cooking process, the height position and the placing angle of the steaming and baking tray 5 can be adjusted without opening the door body of the cooking equipment, and the use safety is improved. Moreover, the driving assembly 3 is arranged outside the inner container 1, so that the temperature of the environment where the driving assembly 3 is located can be reduced, and the driving assembly 3 is prevented from being damaged due to the excessively high temperature.

[0043] As shown in Figure 3 and Figure 5 Since the edge of the steaming and baking tray 5 is generally provided with a turned edge, the lifting assembly 2 further comprises a limiting piece 23 connected with one end of the supporting piece 22 away from the lifting piece 21, and the top end of the limiting piece 23 protrudes from the supporting piece 22. When the steaming and baking tray 5 is placed on the supporting piece 22, the part of the top end of the limiting piece 23 protruding from the supporting piece 22 can be clamped into the turned edge, and the turned edge and the limiting piece 23 can cooperate to prevent the steaming and baking tray 5 from sliding away from the supporting piece 22, so that the stability and reliability of the steaming and baking tray 5 placed on the supporting piece 22 can be ensured. Of course, the limiting piece 23 can also protrude from the supporting piece 22 at both ends in the height direction of the inner container 1, and when the lifting assembly 2 is installed, the limiting piece 23 can be taken as the top end at any one end of the inner container 1, so as to facilitate the machining and assembly of the lifting assembly 2.

[0044] As shown in Figure 3 and Figure 6As shown, the cooking device further comprises four sealing members 4 arranged one-to-one with the lifting grooves 111, the sealing members 4 are arranged in the corresponding lifting grooves 111 and are provided with slits 41 extending along the height direction of the inner container 1, the support members 22 extend into the inner container 1 through the corresponding slits 41. The sealing members 4 can block the lifting grooves 111 to prevent the heat, steam, oil stains and the like in the inner container 1 from overflowing out of the inner container 1 through the lifting grooves 111, so as to ensure the cooking temperature and the cooking effect in the inner container 1, and also prevent the temperature of the elements arranged between the shell and the inner container 1 of the cooking device from being too high or being polluted by oil stains. Specifically, the sealing member 4 comprises two sheet structures with elasticity, the slit 41 is formed between the two sheet structures, and in the lifting process of the lifting assembly 2, the two sheet structures will be deformed at the position where the support member 22 is located, so that the slit 41 is opened, and the remaining positions of the two sheet structures will be abutted under the action of their own elasticity, so that the slit 41 is basically closed, preventing the heat, steam, oil stains and the like in the inner container 1 from overflowing out of the inner container 1 through the slit 41. Moreover, the sealing member 4 can be fixed to the side wall 11 by means of gluing, screws, interference fit and the like.

[0045] As shown in Figure 3 and Figure 5 In an embodiment, the cross section of the support member 22 in the vertical direction is shuttle-shaped. Specifically, along the height direction of the inner container 1, the cross section of the support member 22 is in the shape of gradually narrowing from the middle to both ends. In this way, the support member 22 can open the slit 41 in the lifting process, reduce the resistance of the support member 22 in the lifting process, and avoid jamming. At the same time, it is also beneficial to improve the closing effect of the slit 41 in the area where the support member 22 does not pass. Of course, in other embodiments, the cross section of the support member 22 in the vertical direction can also be in other shapes such as elliptical, waist-shaped and the like, and the embodiments of the present application do not make specific limitations here.

[0046] As shown in Figure 4As shown, in an embodiment, the driving assembly 3 comprises a screw rod 31 and a driving member 32, the screw rod 31 extends along the height direction of the inner container 1, the lifting member 21 is threadedly connected with the screw rod 31, and the driving member 32 is capable of driving the screw rod 31 to rotate relative to the inner container 1 about the axis of the screw rod 31, so as to drive the lifting member 21 to lift or lower. The driving member 32 is capable of driving the screw rod 31 to rotate in the forward direction or in the reverse direction relative to the inner container 1 about the axis of the screw rod 31, and the lifting member 21 is threadedly connected with the screw rod 31, so that the lifting member 21 is lifted or lowered along the height direction of the inner container 1. The driving assembly 3 has a simple structure and a low cost, so as to facilitate the processing and assembly of the driving assembly 3 and the lifting assembly 2. The driving member 32 can be a driving motor, which has a simple structure, a low cost, and a small occupied space in the cooking device. Alternatively, the driving member 32 can be a gearbox, a hydraulic motor, a mechanical transmission assembly, or other driving elements capable of driving the screw rod 31 to rotate about the axis of the screw rod 31. Of course, in other embodiments, the driving assembly 3 can comprise an electric guide rail, a pneumatic cylinder, a hydraulic cylinder, or other driving elements capable of driving the lifting member 21 to lift or lower along the height direction of the inner container 1, which are not limited herein.

[0047] As shown in FIGS. 1 and 2, Figure 4 and Figure 6 As shown, the driving assembly 3 further comprises a housing 33 sleeved outside the screw rod 31, the housing 33 is provided with a guide groove 331 extending along the height direction of the inner container 1; the lifting member 21 comprises a sleeve portion 211 and an inner thread portion 212 protruding from the inner wall of the sleeve portion 211, the sleeve portion 211 is sleeved outside the housing 33 in a liftable manner, and the inner thread portion 212 extends into the housing 33 through the guide groove 331, so as to be threadedly connected with the screw rod 31. The housing 33 can protect the screw rod 31, the guide groove 331 can limit the movement direction of the inner thread portion 212, prevent the lifting member 21 from rotating together with the screw rod 31 about the axis of the screw rod 31, and ensure that the screw rod 31 can be threadedly connected with the inner thread portion 212 when the screw rod 31 rotates, so that the lifting member 21 can stably lift or lower along the axis of the screw rod 31. The central angle of the inner thread portion 212 is equal to or slightly smaller than the central angle of the guide groove 331, so as to ensure that the inner thread portion 212 can smoothly slide along the axis of the screw rod 31 in the guide groove 331, and cannot move along the circumference of the screw rod 31 in the guide groove 331.

[0048] As shown in FIGS. 1 and 2, Figures 5 to 6As shown, in an embodiment, the number of guide grooves 331 is two, the two guide grooves 331 are oppositely arranged on two sides of the shell 33, and the number of inner threaded parts 212 is two and arranged one by one with the guide grooves 331. The two inner threaded parts 212 are oppositely arranged on two sides of the sleeve part 211 to ensure the balance of the lifting piece 21 and avoid the lifting piece 21 tilting to cause the jamming between the inner threaded part 212 and the screw rod 31, thereby ensuring that the lifting piece 21 can smoothly ascend and descend along the axis of the screw rod 31. Moreover, the two guide grooves 331 and the two inner threaded parts 212 will not cause the structure of the shell 33 and the lifting piece 21 to be too complex, so as to facilitate the processing and assembly of the lifting assembly 2 and the driving assembly 3. Of course, in other embodiments, the number of guide grooves 331 can also be set to one, three, four or more according to actual needs, as long as the lifting piece 21 can ascend and descend along the axis of the screw rod 31 and will not rotate with the screw rod 31 around the axis of the screw rod 31, and the embodiments of the utility model do not make specific limitations here.

[0049] As shown, Figures 5 to 6 As shown, the lifting piece 21 includes a plane 213 facing the side wall 11. During the process of the lifting piece 21 ascending and descending along the axis of the screw rod 31, the plane 213 can be attached to the outer side of the side wall 11 or the outer side of the sealing piece 4 to prevent the lifting piece 21 from rotating with the screw rod 31 around the axis of the screw rod 31, so that the lifting piece 21 can stably ascend and descend along the axis of the screw rod 31.

[0050] Further, the cooking equipment also includes a controller (not shown in the figure), which is electrically connected with the four driving assemblies 3 and is used for controlling the driving assemblies 3 to act. Specifically, before starting cooking, the controller first controls the four driving motors to simultaneously drive the corresponding screw rods 31 to reverse, so that the four lifting pieces 21 all descend to the lowest position, and sets the lowest position of the lifting piece 21 as the initial position. Wherein, whether the lifting piece 21 is lowered in place can be judged by the current change of the driving motor. After starting cooking, the controller can control the four driving motors to simultaneously or independently drive the corresponding screw rods 31 to rotate forward or reverse according to the set menu or program, so that the corresponding lifting piece 21 ascends or descends, so as to adjust the position of the steaming and baking tray 5 to the preset height position and placement angle, and also can make the steaming and baking tray 5 do periodic or non-periodic motion according to the program setting, so that the cooking equipment has higher cooking freedom in the cooking process, realizes intelligent cooking, and improves the cooking effect.

[0051] Wherein, the cooking equipment can be a steaming and baking oven and other equipment that needs to use the steaming and baking tray 5 to place food materials, and the embodiments of the utility model do not make specific limitations here.

[0052] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
