Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a frying and baking machine. BACKGROUND

[0002] The frying and baking machine is favored by consumers because it can be used to fry, bake and sear various foods and can achieve efficient and fast cooking. In order to adapt to the cooking needs of foods of different thicknesses and degrees of expansion, an adjusting mechanism is provided on the frying and baking machine to adjust the distance between the upper cover assembly and the base assembly, so that the food can be prevented from being compacted by the upper baking tray of the upper cover assembly during cooking. However, in the prior art, the adjusting mechanism has a complex structure, resulting in high production cost. SUMMARY

[0003] Therefore, it is necessary to provide a frying and baking machine with a very simple structure for adjusting the distance between the upper cover assembly and the base assembly.

[0004] A frying and baking machine comprises a base assembly, an upper cover assembly and a jacking mechanism, the jacking mechanism being used to jack up the upper cover assembly to adjust the distance between the upper cover assembly and the base assembly, the jacking mechanism comprising a jacking bracket and a jacking piece, the jacking bracket being movably mounted on the base assembly, the jacking bracket comprising a connecting rod and a jacking portion connected to both ends of the connecting rod, the jacking portion having a jacking surface, the jacking surface being at least partially gradually rising in height, the jacking piece being movably arranged between the jacking portion and the upper cover assembly, one end of the jacking piece being in contact with the jacking surface, and the other end of the jacking piece being used to support the upper cover assembly, when the jacking bracket moves relative to the base assembly, the jacking piece slides along the jacking surface to realize upward and downward movement.

[0005] The frying and baking machine provided by the present application can prevent the food from being compacted due to the too small distance between the upper cover assembly and the base assembly, and ensure the soft taste of the food. Since the jacking mechanism comprises a connecting rod and a jacking portion connected to both ends of the connecting rod, and is a non-ring structure, the jacking mechanism has a very simple structure, which is conducive to reducing the production cost. In addition, since the jacking portion is connected to both ends of the connecting rod, the jacking bracket occupies a small space as a whole, which is conducive to the miniaturization design of the frying and baking machine.

[0006] In one of the embodiments, the jacking piece comprises a support block used to support the upper cover assembly, and when the support block supports the upper cover assembly, the support block is in surface contact with the upper cover assembly.

[0007] In this way, the jacking piece can stably support the upper cover assembly, so that the upper cover assembly can be lifted or lowered as a whole without being high on one side and low on the other side.

[0008] In one of the embodiments, the support surface of the support block for supporting the upper cover assembly is a support surface, and the area of the support surface is S, S≥90mm 2 .

[0009] In this way, the contact area between the support block and the upper cover assembly can be ensured to be sufficient, so that the support block can stably support the upper cover assembly.

[0010] In one of the embodiments, the support surface is a rectangle, wherein the length is≥30mm, and the width is≥3mm.

[0011] In this way, the support block can stably support the upper cover assembly, so that the upper cover assembly can maintain a horizontal state when it is raised or lowered. In addition, this arrangement allows the support block to be arranged on one side of the base assembly deviating from the center position, facilitating the reasonable arrangement of other components of the base assembly.

[0012] In one of the embodiments, the jacking member further comprises a jacking rod, the jacking rod is fixedly connected to the lower end of the support block, and the end of the jacking rod away from the support block contacts the jacking surface.

[0013] In this way, the jacking rod can drive the support block to move up and down along the jacking surface, thereby jacking the upper cover assembly. The jacking member comprises a jacking rod connected to the lower end of the support block, and the cross-sectional area of the jacking rod is smaller than that of the support block, facilitating the installation of the jacking member.

[0014] In one of the embodiments, the base assembly is provided with a limiting groove and a limiting channel in communication, the limiting channel is arranged below the limiting groove, the support block is at least partially arranged in the limiting groove, and the jacking rod is arranged in the limiting channel.

[0015] The base assembly is provided with a limiting groove and a limiting channel, which limits the installation position of the jacking member and the up-and-down movement position of the jacking member.

[0016] In one of the embodiments, a step is formed between the limiting groove and the limiting channel to limit the support block in the limiting groove.

[0017] A step is formed between the limiting groove and the limiting channel to limit the downward movement range of the support block, preventing the support block from falling out of the limiting channel.

[0018] In one of the embodiments, the jacking mechanism further comprises an elastic member, the elastic member connects the jacking member and the base assembly to apply a downward moving force to the jacking member, so that the jacking member maintains contact with the jacking surface.

[0019] In this way, the lifting part can always abut against the lifting surface when the lifting surface moves relative to the lifting part, so that the lifting part can timely descend with the lifting surface when the height of the upper cover assembly is adjusted downward, thereby avoiding the situation that the upper cover assembly suddenly falls downward.

[0020] In one of the embodiments, the limiting channel has a limiting boss on the inner wall, the outer wall of the jacking rod has a limiting convex ring, the elastic member is a spring, the spring is sleeved on the outer side of the jacking rod, and the upper and lower ends of the spring abut against the limiting boss and the limiting convex ring respectively.

[0021] In this way, the spring provides a downward moving force for the lifting part, so that the jacking rod always abuts against the lifting surface.

[0022] In one of the embodiments, the lifting surface includes a lifting section with gradually rising height and a platform section with constant height, and the platform section is connected to the upper end of the lifting section.

[0023] In this way, when the upper cover assembly is lifted to the highest position, that is, the distance between the upper cover assembly and the base assembly is the largest, the platform section can stably support the lifting part, thereby stably supporting the upper cover assembly and avoiding the situation that the upper cover assembly slips.

[0024] In one of the embodiments, the connecting rod is rotatably installed on the base assembly through a rotating shaft, and the lifting parts at the two ends of the connecting rod are arranged in rotational symmetry.

[0025] In this way, the jacking bracket has a small moving space and does not occupy too much space inside the base assembly.

[0026] In one of the embodiments, the base assembly further has a limiting member, the limiting member has a limiting hole, the connecting rod has a limiting rod, the limiting rod extends into the limiting hole and is in sliding fit with the limiting hole, so as to limit the rotating range of the connecting rod through the limiting hole.

[0027] The limiting member limits the rotating range of the connecting rod, thereby avoiding the situation that the jacking bracket is excessively rotated by the user.

[0028] In one of the embodiments, the base assembly includes a lower baking tray, a lower shell and a lower inner liner, the lower inner liner is arranged on the inner side of the lower shell, the lower baking tray is arranged above the lower inner liner, the connecting rod and the limiting member are both installed on the side of the lower inner liner facing the lower shell, and the connecting rod is located between the limiting member and the lower inner liner.

[0029] In this way, the limiting member also supports the jacking bracket, thereby strengthening the support of the jacking bracket on the lifting part.

[0030] In one of the embodiments, the limiting member is in the shape of a circular arc, and the limiting hole extends along the length direction of the limiting member.

[0031] In this way, the structure is very simple, and the length of the limiting hole limits the moving range of the limiting rod, thereby limiting the rotation angle of the connecting rod.

[0032] In one of the embodiments, the connecting rod comprises a horizontal cross rod and vertical rods connected to the two ends of the cross rod and extending upward, and the cross rod is rotatably installed on the base assembly through a rotating shaft, and the vertical rods are connected to the jacking part.

[0033] In this way, the vertical rods provide the jacking part with a mounting space with a certain height, facilitating the connection of the jacking part and the connecting rod.

[0034] In one of the embodiments, the upper cover assembly is rotatably connected to the base assembly through a hinge, and the jacking mechanism is arranged on the side of the base assembly close to the hinge.

[0035] In this way, the jacking support is installed on the side of the base assembly deviated from the center position, so that a slot can be arranged at the center position of the lower shell and the lower inner liner of the base assembly, that is, the jacking mechanism does not affect the arrangement of the slot, so that the grill can develop more functions without changing the appearance and volume.

[0036] In one of the embodiments, the base assembly comprises a lower baking tray, a lower shell and a lower inner liner, the lower inner liner is arranged on the inner side of the lower shell, the lower baking tray is arranged above the lower inner liner, the jacking support is arranged between the lower inner liner and the lower shell, and the jacking member at least partially protrudes from the lower inner liner to support the upper cover assembly.

[0037] In this way, the jacking support is hidden in the lower shell, which does not affect the appearance of the grill.

[0039] The arrangement of the pulling rod greatly facilitates the operation of the user.

[0040] In one of the embodiments, the upper cover assembly comprises an upper baking tray, and the height difference between the highest point and the lowest point of the upper baking tray is 5mm-40mm.

[0041] In this way, the cooking requirements of most food materials can be met. BRIEF DESCRIPTION OF DRAWINGS

[0052] ​​In order to make the above objectives, features and advantages of the present application more clear and comprehensible, the detailed description of the specific embodiments of the present application is made below with reference to the accompanying drawings. In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many different ways other than the one described herein, and one of ordinary skill in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0053] It is to be noted that when a component is referred to as being "on" or "disposed on" another component, it can be directly on the other component or there can be intervening components present.

The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the associated listed items.

[0057] See Figures 1 to 3The application provides a grill, which comprises a base assembly 10, an upper cover assembly 20 and a jacking mechanism 30. The base assembly 10 comprises a lower grill plate 11, and the upper cover assembly 20 comprises an upper grill plate 21. The upper cover assembly 20 is reversibly connected to the base assembly 10, so that the upper grill plate 21 can be engaged with the lower grill plate 11. The jacking mechanism 30 is used to jack up the upper cover assembly 20, so as to adjust the distance between the upper cover assembly 20 and the base assembly 10, and accordingly, the distance between the upper grill plate 21 and the lower grill plate 11, so that the grill can be used to cook food with different thicknesses or different degrees of expansion. Adjusting the distance between the upper cover assembly 20 and the base assembly 10 by the jacking mechanism 30 can avoid the food being pressed and compacted due to the small distance between the upper cover assembly 20 and the base assembly 10 (or the small distance between the upper grill plate 21 and the lower grill plate 11), and ensure the soft taste of the food.

[0058] In the application, the jacking mechanism 30 comprises a jacking bracket 31 and a jacking piece 32. The jacking bracket 31 is movably mounted on the base assembly 10. The jacking bracket 31 comprises a connecting rod 311 and a jacking portion 312 connected to two ends of the connecting rod 311. The jacking portion 312 has a jacking surface 3121, and the height of at least part of the jacking surface 3121 gradually increases.

[0059] The jacking piece 32 is movably arranged between the jacking portion 312 and the upper cover assembly 20. One end of the jacking piece 32 is in contact with the jacking surface 3121, and the other end is used to support the upper cover assembly 20. When the jacking bracket 31 moves relative to the base assembly 10, the jacking piece 32 slides along the jacking surface 3121 to realize the up-and-down movement.

[0060] The grill connects the jacking portion 312 through the connecting rod 311. The jacking portion 312 is provided with the jacking surface 3121, and the jacking piece 32 slides along the jacking surface 3121 to realize the up-and-down movement, so that the jacking mechanism 30 jacks up and lowers the upper cover assembly 20 to adjust the distance between the upper cover assembly 20 and the base assembly 10. The jacking mechanism 30 has a very simple structure, which is conducive to reducing the production cost. Since the jacking portion 312 is connected to two ends of the connecting rod 311, the jacking bracket 31 occupies a small space, which is conducive to the miniaturization design of the grill.

[0061] Please refer to Figure 1The upper cover assembly 20 further comprises an upper shell 22, and the upper baking tray 21 is mounted on the upper shell 22. In this embodiment, the upper end of the jacking member 32 can be supported on the upper baking tray 21, and the whole upper cover assembly 20 is supported by supporting the upper baking tray 21. As can be seen, the distance between the upper cover assembly 20 and the base assembly 10 can be adjusted by the up-down movement of the jacking member 32. In addition, the jacking member 32 can also be supported on the upper shell 22, and the upper shell 22 is lifted by the jacking member 32 to drive the upper baking tray 21 to rise and fall.

[0062] Please refer to Figure 4 The base assembly 10 further comprises a lower shell 12 and a lower inner liner 13, the lower inner liner 13 is arranged inside the lower shell 12, and the lower baking tray 11 is arranged above the lower inner liner 13. The jacking support 31 is arranged between the lower inner liner 13 and the lower shell 12, and the jacking member 32 at least partially protrudes from the lower inner liner 13 to support the upper cover assembly 20. In this way, the jacking support 31 is hidden in the lower shell 12, and does not affect the appearance of the grill.

[0063] Further, the jacking member 32 comprises a support block 321 for supporting the upper cover assembly 20, and the support block 321 and the upper cover assembly 20 are in surface contact when the support block 321 supports the upper cover assembly 20. In this way, it is beneficial to the jacking member 32 to stably support the upper cover assembly 20, so that the upper cover assembly 20 can be lifted or lowered as a whole, and the situation of one side being higher and the other side being lower will not occur.

[0064] In the prior art, the jacking support is generally in a circular ring structure, and the overall volume is large, and the jacking member is a rod, and the jacking member and the upper cover assembly are in point contact, and the jacking support needs to be installed at the center position of the base assembly, that is, the center of the circular ring-shaped jacking support and the center of the upper baking tray are on the same vertical line, and more than three jacking members need to be provided, otherwise, it is difficult for the jacking member to stably support the upper baking tray as a whole.

[0065] The grill provided in the present application comprises a jacking support 31 comprising a connecting rod 311 and a jacking part 312 connected to both ends of the connecting rod 311, and the jacking support 31 is a non-ring structure relative to the circular ring-shaped support, and the structure is simpler and the overall volume is smaller. In this embodiment, the two ends of the connecting rod 311 are connected to the jacking part 312, and one jacking member 32 is provided corresponding to each jacking part 312, that is, the number of jacking members 32 is two, and only two jacking members 32 are needed to stably support the upper cover assembly 20, and the structure is simpler relative to the prior art. Since the support block 321 and the upper cover assembly 20 are in surface contact, the jacking support 31 does not need to be installed at the center position of the base assembly 10, and the installation of the jacking support 31 is more flexible.

[0066] Please refer to Figure 5Further, the support block 321 is used to support the upper cover assembly 20, and the surface of the support block 321 is a support surface 3211. In this embodiment, the support block 321 supports the upper cover assembly 20 through the top surface, and thus the top surface of the support block 321 is the support surface 3211. The area of the support surface 3211 is S, and S≥90mm 2 In this way, the support block 321 and the upper cover assembly 20 have sufficient contact area, and thus the support block 321 can stably support the upper cover assembly 20.

[0067] In some preferable embodiments, S is 150mm 2 -900mm 2 In this way, the support block 321 can stably support the upper cover assembly 20, and the support surface 3211 will not be too large to affect the installation of the support block 321 on the base assembly 10.

[0068] In this embodiment, the support block 321 is a cuboid, and thus the support surface 3211 of the support block 321 is a rectangle, and the length is≥30mm and the width is≥3mm. In this way, the support block 321 can stably support the upper cover assembly 20, and the upper cover assembly 20 can remain horizontal when it is raised or lowered. In this way, the support block 321 can be arranged on one side of the base assembly 10 that deviates from the center, and thus other components of the base assembly 10 can be arranged reasonably. In some specific embodiments, the length of the support surface 3211 can be 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm, 50mm, 51mm, 52mm, 53mm, 54mm, 55mm, 56mm, 57mm, 58mm, 59mm, 60mm, 65mm, 70mm, 75mm, or 80mm, etc. The width of the support surface 3211 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm, etc.

[0069] Please refer to Figure 1 In this embodiment, the base assembly 10 is substantially rectangular, the support block 321 is arranged on the long side of the base assembly 10, and the long side direction of the support block 321 is the same as the long side direction of the base assembly 10.

[0070] In this embodiment, the support surface 3211 is a rectangle. It can be understood that the rectangle is not limited to a rectangle with four corners being strict right angles. A rectangle with four corners being rounded or bevelled is also regarded as a rectangle. Of course, the shape of the support surface 3211 is not limited to a rectangle. It can also be an ellipse, a rhombus, a sector, a shuttle shape or other shapes.

[0071] Please refer to Figure 5 , further, the jacking member 32 further comprises a jacking rod 322, the jacking rod 322 is fixedly connected to the lower end of the support block 321, and the end of the jacking rod 322 away from the support block 321 contacts the jacking surface 3121. In this way, the jacking rod 322 is moved along the jacking surface 3121 to drive the support block 321 to move up and down, thereby jacking the upper cover assembly 20. The jacking member 32 comprises the jacking rod 322 connected to the lower end of the support block 321, and the cross-sectional area of the jacking rod 322 is smaller than that of the support block 321, facilitating the installation of the jacking member 32. Further, the end of the jacking rod 322 contacting the jacking surface 3121 is a spherical surface, which can reduce the friction between the jacking rod 322 and the jacking surface 3121, and more easily make the jacking rod 322 rise and fall.

[0072] Please refer to Figure 4 , Figure 6 and Figure 7 , in order to install the jacking member 32, the base assembly 10 is provided with a limiting groove 131 and a limiting channel 132 in communication, the limiting channel 132 is arranged below the limiting groove 131, the support block 321 is arranged at least partially in the limiting groove 131, and the jacking rod 322 is arranged in the limiting channel 132. The base assembly 10 limits the installation position of the jacking member 32 and the position of the jacking member 32 moving up and down by arranging the limiting groove 131 and the limiting channel 132. It can be understood that in this embodiment, the limiting groove 131 and the limiting channel 132 are arranged on the lower inner liner 13. The upper end of the support block 321 extends from the upper end of the lower inner liner 13 to support the upper cover assembly 20, and the jacking rod 322 extends from the lower end of the lower inner liner 13 to abut against the jacking surface 3121.

[0073] Please refer to Figure 7 , a step is formed between the limiting groove 131 and the limiting channel 132 to limit the support block 321 in the limiting groove 131. In this way, the step is formed between the limiting groove 131 and the limiting channel 132 to limit the range of the support block 321 moving downward, which can prevent the support block 321 from falling out of the limiting channel 132.

[0074] The jacking mechanism 30 further comprises an elastic member 33, which is connected to the jacking member 32 and the base assembly 10 to apply a downward moving force to the jacking member 32 so as to keep the jacking member 32 in contact with the jacking surface 3121. In this way, it can be ensured that the jacking member 32 can always abut against the jacking surface 3121 when the jacking surface 3121 moves relative to the jacking member 32, avoiding the situation that the jacking member 32 cannot timely drop with the jacking surface 3121 when the height of the upper cover assembly 20 is adjusted downward, so that the upper cover assembly 20 suddenly drops downward.

[0075] Please refer to Figure 7 , the inner wall of the limiting channel 132 is provided with a limiting boss 133, the outer wall of the jacking rod 322 is provided with a limiting convex ring 3221, the elastic member 33 is a spring, and the upper and lower ends of the spring abut against the limiting boss 133 and the limiting convex ring 3221 respectively. In this way, the spring provides a downward moving force to the jacking member 32, so that the jacking rod 322 always abuts against the jacking surface 3121.

[0076] When the jacking member 32 and the elastic member 33 are installed, the spring can be sleeved on the outer side of the jacking rod 322 first, then the jacking rod 322 sleeved with the spring is installed into the limiting channel 132 from below the limiting channel 132, and the supporting block 321 is installed into the limiting groove 131 from above the limiting groove 131, and then the supporting block 321 and the jacking rod 322 are connected together. The installation process is relatively simple and easy to operate. The supporting block 321 and the jacking rod 322 can be connected in a threaded connection or a clamping manner, which is simple and easy to operate.

[0077] Please refer to Figure 5 In an embodiment, the jacking surface 3121 comprises a lifting section 3121a with gradually rising height and a platform section 3121b with constant height, and the platform section 3121b is connected to the upper end of the lifting section 3121a. In this way, when the upper cover assembly 20 is jacked to the highest position, that is, the distance between the upper cover assembly 20 and the base assembly 10 is the largest, the platform section 3121b can stably support the jacking member 32, thereby stably supporting the upper cover assembly 20 and avoiding the situation that the upper cover assembly 20 slips. Further, the lifting section 3121a can be an inclined plane, or an arc-shaped surface with convex or concave shape, which is not limited in the present application.

[0078] In the present embodiment, the jacking part 312 is a plate body, and the top surface of the jacking part 312 constitutes the jacking surface 3121.

[0079] Please refer to Figure 2 , Figure 3 and Figure 5Furthermore, the height difference between the highest point and the lowest point of the upper baking pan 21 is 5mm-40mm, which can meet the cooking needs of most ingredients. It is understood that the upper baking pan 21 is raised to its highest point when the distance between the upper cover assembly 20 and the base assembly 10 is at its maximum. When the distance between the upper cover assembly 20 and the base assembly 10 is at its minimum, the upper baking pan 21 is at its lowest point. At this time, the lifting member 32 can contact the upper cover assembly 20, or there can be a certain gap between it and the upper cover assembly 20 (at this time, the lifting member 32 does not serve to support the upper cover assembly 20). This application does not impose any limitations on this.

[0080] In one embodiment, when the lower end of the lifting member 32 abuts against the highest point of the lifting surface 3121, the upper baking tray 21 is lifted to the highest point; when the lower end of the lifting member 32 abuts against the lowest point of the lifting surface 3121, the upper baking tray 21 is located at the lowest point. Therefore, the height difference between the highest and lowest points of the lifting surface 3121 is... Figure 5 The height difference between the highest point and the lowest point of the upper baking pan 21 is represented by H. Of course, in other embodiments, when the upper baking pan 21 is raised to the highest point, the lower end of the lifting member 32 may not be located at the highest point of the lifting surface 3121; similarly, when the upper baking pan 21 is at the lowest point, the lower end of the lifting member 32 may not be located at the lowest point of the lifting surface 3121.

[0081] In some specific embodiments, the height difference between the highest point and the lowest point of the upper baking tray 21 is 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, etc.

[0082] When the upper baking pan 21 is at its lowest point, the distance between the upper baking pan 21 and the lower baking pan 11 is considered to be 0mm. Figure 3 As shown, the distance between the upper baking tray 21 and the lower baking tray 11 is 0mm at this time, and correspondingly, the distance between the upper cover assembly 20 and the base assembly 10 is also 0mm. In one embodiment, the height difference between the highest point and the lowest point of the upper baking tray 21 is 40mm. In this embodiment, if... Figure 2As shown, at this time, the upper baking tray 21 is lifted to the highest point, and the distance between the upper baking tray 21 and the lower baking tray 11 is 40 mm. Correspondingly, the distance between the upper cover assembly 20 and the base assembly 10 is also 40 mm. In this embodiment, the distance between the upper baking tray 21 and the lower baking tray 11 can be adjusted within a range of 0 mm to 40 mm. That is, the distance between the upper baking tray 21 and the lower baking tray 11 can be any value within a range of 0 mm to 40 mm. In this way, the user can adjust the upper baking tray 21 to a suitable height as needed, so that the upper baking tray 21 does not press the food too tightly, and unnecessary heat loss caused by too large distance between the upper baking tray 21 and the lower baking tray 11 can be avoided.

[0083] Please refer to Figure 5 The connecting rod 311 includes a horizontal cross rod 3111 and vertical rods 3112 connected to both ends of the cross rod 3111 and extending upward. The vertical rods 3112 are connected to the lifting part 312. In this way, the vertical rods 3112 provide a mounting space with a certain height for the lifting part 312, facilitating the connection of the lifting part 312 and the connecting rod 311.

[0084] In this embodiment, the vertical rods 3112 are connected to the upper end of the lifting part 312. Of course, in other embodiments, the vertical rods 3112 can be connected to the lower end of the lifting part 312 or the middle part of the lifting part 312, which is not limited in the present application.

[0085] Please refer to Figure 4 and Figure 8 The cross rod 3111 is rotatably mounted to the base assembly 10 through the rotating shaft 34. In this way, the lifting surface 3121 can be moved relative to the lifting part 32 by rotating the lifting bracket 31, that is, the lifting part 32 moves along the lifting surface 3121 to realize up and down movement. In this embodiment, the rotating shaft 34 is fixedly connected to the lower inner liner 13, and the cross rod 3111 is provided with a shaft hole. The rotating shaft 34 penetrates the shaft hole to rotatably mount the cross rod 3111 to the lower inner liner 13. Of course, in other embodiments, the rotating shaft 34 can be fixedly connected to the cross rod 3111, and the lower inner liner 13 is provided with a shaft hole matched with the rotating shaft 34. The rotating shaft 34 is rotatably mounted to the shaft hole.

[0086] In this embodiment, the connecting rod 311 is rotatably mounted to the base assembly 10 through the rotating shaft 34, and the lifting parts 312 at both ends of the connecting rod 311 are arranged in rotational symmetry. The lifting bracket 31 has a small movement space and does not occupy too much space inside the base assembly 10. Of course, in other embodiments, the lifting bracket 31 can be movably mounted to the base assembly 10 in other ways, such as translationally. Correspondingly, the lifting parts 312 at both ends of the connecting rod 311 are arranged in axial symmetry.

[0087] Please refer to Figure 8Further, the base assembly 10 is further provided with a limiting piece 14, in the embodiment, the limiting piece 14 is arranged on the side of the lower inner liner 13 facing the lower shell 12. The limiting piece 14 is provided with a limiting hole 141, and the connecting rod 311 is provided with a limiting rod 3113, the limiting rod 3113 extends into the limiting hole 141 and is in sliding fit with the limiting hole 141, so as to limit the rotation range of the connecting rod 311 through the limiting hole 141. The limiting piece 14 is arranged to limit the rotation range of the connecting rod 311, so as to avoid the situation that the user excessively rotates the jacking support 31 during operation.

[0088] Further, the connecting rod 311 and the limiting piece 14 are both arranged on the side of the lower inner liner 13 facing the lower shell 12, and the connecting rod 311 is located between the limiting piece 14 and the lower inner liner 13. In this way, the limiting piece 14 also supports the jacking support 31, so as to strengthen the support of the jacking support 31 on the jacking piece 32.

[0089] In the embodiment, the limiting piece 14 is in arc shape, and the limiting hole 141 is arranged in the direction of the limiting piece 14, and correspondingly, the limiting hole 141 is in arc linear hole. In this way, the structure is very simple, the length of the limiting hole 141 limits the movement range of the limiting rod 3113, so as to limit the rotation angle of the connecting rod 311.

[0090] In the embodiment, the two sides of the rotating shaft 34 are each provided with a limiting piece 14, and the two limiting pieces 14 are symmetrically arranged, so that the rotation limitation and support of the connecting rod 311 are more stable.

[0091] Please refer to Figures 1 to 4 Further, the jacking support 31 further comprises a push rod 313 connected to the jacking part 312, and the lower shell 12 is provided with an adjusting hole 122, the push rod 313 extends out of the lower shell 12 from the adjusting hole 122, and the push rod 313 can move along the adjusting hole 122. In this way, the jacking support 31 can be rotated by moving the push rod 313, so that the jacking piece 32 moves along the jacking surface 3121 to realize the up and down movement, so that the upper cover assembly 20 moves up and down to realize the adjustment of the distance between the upper cover assembly 20 and the base assembly 10. The push rod 313 is arranged, which greatly facilitates the user operation.

[0092] The jacking mechanism 30 provided in the application has simple structure and small space occupation. The jacking support 31 can be installed at the central position of the base assembly 10, or can be installed at one side deviating from the central position of the base assembly 10.

[0093] The upper cover assembly 20 is rotatably connected to the base assembly 10 by the hinge 40. In an embodiment, the jacking mechanism 30 is arranged on one side of the base assembly 10 close to the hinge 40. Thus, the jacking support 31 is mounted on the base assembly 10 on one side away from the center. In this embodiment, the lower shell 12 and the lower inner liner 13 are both provided with a slot 121 for avoiding the handle of the baking tray, so that the lower baking tray 11 with handle can also be applied to the lower shell 12 and the lower inner liner 13, that is, the lower shell 12 and the lower inner liner 13 can be adapted to more types of lower baking trays 11. Since the jacking mechanism 30 is arranged on one side of the base assembly 10 close to the hinge 40, the slot 121 can be arranged at the center of the lower shell 12 and the lower inner liner 13, that is, the jacking mechanism 30 does not affect the arrangement of the slot 121, so that the grill can develop more functions without changing the shape and volume of the lower shell 12.

[0094] The grill provided by the embodiment has the upper baking tray 21 and the lower baking tray 11 both being rectangular baking trays, and the upper shell 22 and the lower shell 12 also being rectangular structures. The lever 313 extends from one side of the long side of the lower shell 12, and the lifting of the upper baking tray 21 can be realized by horizontally pushing the lever 313, so as to adjust the distance between the upper baking tray 21 and the lower baking tray 11. Of course, in other embodiments, the upper baking tray 21 and the lower baking tray 11 can also be circular baking trays. Since the jacking support 31 includes the connecting rod 311 and the jacking part 312 connected to both ends of the connecting rod 311, the structure is very simple, the volume is small, and the application is also more flexible. Both the rectangular baking tray and the circular baking tray can be supported and adjusted in height by the jacking support 31.
