Description

Technical Field

[0001] This application belongs to the field of kitchen appliance technology, specifically relating to a grill with adjustable cooking space. Background Technology

[0002] A typical grill pan generally consists of an upper grill pan assembly and a lower grill pan assembly. These assemblies are connected by a hinge mechanism, allowing them to rotate relative to each other for opening and closing. This hinge mechanism has a certain amount of floating space, enabling the upper and lower grill pan assemblies to move relative to each other under external force. When the upper grill pan assembly is closed over the lower grill pan assembly, the enclosed space between them forms the cooking space. The height of this cooking space is fixed in its natural state. During cooking, if the thickness of the food exceeds the height of this space, the upper grill pan assembly will press down on the food. During cooking, the food's own surface tension and the expansion force after heating will lift the upper grill pan assembly slightly. However, because the upper grill pan assembly integrates the lid, upper grill pan, heating element, and other structural components, it is quite heavy. This can cause the food to collapse, resulting in a poor appearance and a denser, less tender texture, thus affecting the overall cooking outcome.

[0003] To address the issue of whether a grill can accommodate cooking ingredients of varying thicknesses, it is necessary to consider that the cooking space formed between the upper and lower grill pan components, when closed, can be freely adjusted within a certain height range to accommodate the cooking of ingredients of different thicknesses.

[0004] The prior art discloses a grill, including an upper grill pan and a lower grill pan, with a support base between the upper and lower grill pans for adjusting the height of the cooking cavity. The support base includes a seat body with an internal assembly cavity, a support member and a limiting component installed in the assembly cavity, the support member being adjusted in height and positioned by the limiting component to keep the height of the cooking cavity constant. The assembly cavity includes a vertical cavity and a horizontal cavity, the support member being raised and lowered along the vertical cavity and positioned by the limiting component in the horizontal cavity, the support member including a top plate above the pressure plate and a guide rod below the top plate, a limiting plate fixed to the bottom end of the guide rod in the vertical cavity, the guide rod being positioned between the limiting plate and the pressure plate. A compression spring is fitted onto the section between the plates. The support also includes a positioning rod located below the top plate. The positioning rod has several equidistant positioning slots. The limiting assembly includes a positioning element that can move within the transverse cavity and a return spring located on the inner edge of the positioning element. The inner edge of the positioning element has a positioning post into which the return spring is inserted. The outer edge of the positioning element has a button exposed in the transverse cavity. When the button is pressed, it causes the positioning element to move and disengage from the positioning slot, so that the return spring accumulates a preload force to reset the positioning element. After the support is adjusted to the correct height, the positioning element driven by the return spring is horizontally inserted into the positioning slot at the same height, so that the support is vertically positioned. In this technical solution, adjusting the height of the support component first requires manually pressing a button to disengage the positioning component from the positioning groove on the support component. This manual pressing of the button unlocks the component. After unlocking, the compression spring releases its full stroke, and the support component pops out to its highest position under the force of the spring. If multiple adjustments to the support component's top position between the highest and lowest positions are needed, while keeping the button pressed, the other hand or other fingers of the same hand must apply force to the top plate to press the popped-out support component down to the desired height. Then, releasing the button allows the reset spring to drive the positioning component into the positioning groove, thus locking the support component in place. This entire process involves multiple points of force application, is cumbersome, and provides a poor user experience. Furthermore, the spring is prone to failure during use. If the spring fails, the popping out of the support component and the translation of the positioning component will be affected, resulting in the failure of the cooking space height adjustment. Utility Model Content

[0005] This application provides a grill with adjustable cooking space to solve the technical problems of existing grills that have complex structural designs, complicated operations, and poor user experience in achieving height adjustment of the cooking space.

[0006] The technical solution adopted in this application is as follows:

[0007] An adjustable-space grill includes an upper grill plate assembly and a lower grill plate assembly. The upper grill plate assembly can cover the lower grill plate assembly and cooperate to form a cooking cavity. One of the upper and lower grill plate assemblies is provided with a support base and a support member movably disposed on the support base. The other assembly is provided with a top support surface that abuts against the support member vertically. The support base is provided with a lifting groove, and the lifting groove is provided with at least two locking positions at different heights. The support member is provided with a positioning protrusion, which can be locked or disengaged from the locking positions. The support member can move relative to the support base along the vertical direction of the lifting groove to rise and fall to different locking positions, and the support member can move relative to the support base in the horizontal direction to displace to the corresponding locking position at the current height.

[0008] The support base in this application has at least two locking positions at different heights. The support member has a positioning protrusion, and the support member can move relative to the support base along the vertical and horizontal directions of the lifting groove. This allows the positioning protrusion to engage or disengage with the locking positions at different heights, thereby adjusting the height of the cooking cavity. Throughout the operation, the user only needs to operate the support member itself to complete the lifting and lowering of different heights and the displacement of the corresponding locking positions. The operation is simple and convenient, and switching the position of one support member can be done with one hand without any other auxiliary actions. This flexible and convenient operation significantly improves the user experience. Especially in multi-level adjustable scenarios, users can easily and quickly adjust the height of the cooking cavity by moving the support member vertically and horizontally according to the thickness of the food, preventing excessive compression of the food during cooking and ensuring optimal cooking results. Furthermore, unlike existing technologies that require the force of a spring to maintain the support position, this application eliminates the use of a spring. The support is locked and positioned by the locking of the positioning protrusion and the locking position, thereby avoiding the positioning failure caused by spring failure and ensuring the stability and reliability of the support after position adjustment.

[0009] The lifting groove includes a plurality of horizontal grooves arranged in the vertical direction and a vertical switching guide groove connecting two adjacent horizontal grooves. The locking position is located in the horizontal groove. The support member moves at least in the horizontal direction to switch from the locking position to the vertical switching guide groove, and the support member moves in the vertical direction along the vertical switching guide groove to move from the outlet of one of the horizontal grooves to the inlet of the other horizontal groove.

[0010] In this technical solution, the combination of horizontal grooves and vertical switching guide grooves allows the support component to flexibly switch between horizontal grooves of different heights. This design enables users to easily adjust the distance between the upper and lower baking pan components according to the thickness of the food and cooking needs, ensuring that the height of the cooking cavity matches the current cooking requirements. The locking positions within the horizontal grooves provide precise positioning points for the support component, ensuring stable support at each height. This guarantees the stability of the upper baking pan component during cooking, preventing food from collapsing due to sudden drops or food splattering within the grill. Furthermore, the combination of horizontal grooves and vertical switching guide grooves further reduces operational complexity. Users simply move the support component horizontally to switch the positioning protrusion from one locking position to the vertical switching guide groove, then move it along the vertical switching guide groove to the entrance of another horizontal groove. By horizontally moving the support component again, the positioning protrusion can be moved to the corresponding locking position at the current height, thus switching the cooking cavity height. This design simplifies the operation and improves the user experience. In addition, multiple horizontal grooves are arranged along the vertical direction, and the locking position is located in the horizontal groove, making the entire height adjustment obvious and easy to see. During operation, the user can adjust the height of the cooking cavity without paying special attention, further improving the convenience and efficiency of operation.

[0011] The lifting groove is provided with a guide structure for guiding the positioning protrusion to switch between the horizontal groove and the vertical switching guide groove.

[0012] This technical solution, by incorporating a guide structure within the lifting groove, ensures smooth and accurate switching of the positioning protrusion between the horizontal groove and the vertical switching guide groove, preventing jamming or misalignment during the switching process. This improves the precision and stability of the support component's position adjustment. The guide structure allows users to adjust the support component's height simply by following its guidance, eliminating the need to focus on specific switching details and making the entire adjustment process simpler and faster. Furthermore, the guide structure reduces friction and collision between the positioning protrusion and the inner wall of the support groove, lowering the risk of damage due to improper operation and extending the service life of the support base and support component.

[0013] The guiding structure includes a first guiding part that guides the positioning protrusion from the vertical switching guide groove into the horizontal groove, and a second guiding part that guides the positioning protrusion from the horizontal groove to the vertical switching guide groove; the first guiding part is disposed on the upper side wall of the horizontal groove, and the extension line of the first guiding part extends downward to enter the vertical switching guide groove; the second guiding part is located on the lower side wall of the horizontal groove, and the extension line of the second guiding part extends upward to enter the vertical switching guide groove.

[0014] In this technical solution, the first guide part and the second guide part are located on the upper and lower sidewalls of the horizontal groove, respectively, and their extension lines extend downward and upward into the vertical switching guide groove, respectively. This design ensures that the positioning protrusion can smoothly transition along the first and second guide parts when entering the horizontal groove from the vertical switching guide groove or switching from the horizontal groove to the vertical switching guide groove, reducing jamming and friction. Furthermore, the design of the first and second guide parts can precisely guide the movement path of the positioning protrusion, ensuring more accurate and stable switching between the horizontal groove and the vertical switching guide groove, thereby improving the adjustment accuracy of the support. In addition, the design of the first and second guide parts allows users to adjust the height of the support simply by following the guidance of the first and second guide parts, without needing to pay too much attention to the specific switching details, making the entire adjustment process simpler and faster.

[0015] The lifting trough includes multiple vertical troughs arranged alternately in the horizontal direction, and a horizontal switching guide trough connecting two adjacent vertical troughs. Each vertical trough has a different height dimension. The locking position is located in the vertical trough. The support member moves at least in the vertical direction to switch from the locking position to the horizontal switching guide trough, and the support member moves in the horizontal direction to move from the outlet of one vertical trough to the inlet of another vertical trough.

[0016] In this technical solution, the combination of vertical grooves and horizontal switching guides allows the support component to flexibly switch between different locking positions. This design enables users to easily adjust the distance between the upper and lower baking pan components according to the thickness of the food and cooking needs, ensuring the cooking cavity height matches the current cooking requirements. The locking positions within the vertical grooves provide precise positioning points for the support component, ensuring stable support at each height. This guarantees the stability of the upper baking pan component during cooking, preventing food collapse or splattering caused by sudden drops. Furthermore, the combination of vertical grooves and horizontal switching guides further reduces operational complexity. Users simply move the support component vertically to switch the positioning protrusion from one locking position to the entrance of one of the horizontal switching guides. Moving the support component horizontally then moves the positioning protrusion to the corresponding locking position at the current height, thus switching the cooking cavity height. This design simplifies operation and improves the user experience.

[0017] The lifting groove is provided with a guide structure for guiding the positioning protrusion to switch between the vertical groove and the horizontal switching guide groove.

[0018] This technical solution, by incorporating a guide structure within the lifting groove, ensures smooth and accurate switching of the positioning protrusion between the vertical groove and the horizontal switching guide groove, preventing jamming or misalignment during the switching process. This improves the precision and stability of the support component's position adjustment. The guide structure allows users to adjust the support component's height simply by following its guidance, eliminating the need to focus on specific switching details and making the entire adjustment process simpler and faster. Furthermore, the guide structure reduces friction and collision between the positioning protrusion and the inner wall of the support groove, lowering the risk of damage due to improper operation and extending the service life of the support base and support component.

[0019] The guiding structure includes a third guiding part that guides the positioning protrusion from the horizontal switching guide groove into the vertical groove, and a fourth guiding part that guides the positioning protrusion from the vertical groove to the horizontal switching guide groove; the third guiding part is disposed on the upper side wall of the horizontal switching guide groove, and the extension line of the third guiding part extends upward to enter the vertical groove; the fourth guiding part is located on the lower side wall of the vertical groove, and the extension line of the fourth guiding part extends upward to enter the horizontal switching guide groove.

[0020] In this technical solution, the third guide part is located on the upper side wall of the horizontal switching guide groove, and its extension line extends upward into the vertical groove. The fourth guide part is located on the lower side wall of the vertical groove, and its extension line extends upward into the horizontal switching guide groove. This design ensures that the positioning protrusion can smoothly transition along the third and fourth guide parts when moving from the vertical groove into the horizontal switching guide groove or switching from the horizontal switching guide groove to the vertical groove, reducing jamming and friction. Furthermore, the design of the third and fourth guide parts can precisely guide the movement path of the positioning protrusion, ensuring more accurate and stable switching between the vertical groove and the horizontal switching guide groove, thereby improving the adjustment accuracy of the support. In addition, the design of the third and fourth guide parts allows users to adjust the height of the support simply by following the guidance of the third and fourth guide parts, without needing to pay too much attention to the specific switching details, making the entire adjustment process simpler and faster.

[0021] The support base includes two opposing support blocks. A first opening area is formed between one end of the two support blocks for the support member to extend out and abut against the top support surface. A second opening area is formed between the other ends of the two support blocks for the support member to be exposed. The support member is exposed from the second opening area to have a first force-applying end. The width of the support member is greater than the width of the top support surface so that the support member has a second force-applying end that is exposed and opposite to the first force-applying end.

[0022] In this technical solution, a second open area is formed between the two support blocks for the support component to be exposed. The support component is exposed from the second open area to have a first force-applying end. The width of the support component is greater than the width of the top support surface so that the support component has a second force-applying end that is exposed and opposite to the first force-applying end. This design allows the user to directly hold the support component through the first and second force-applying ends during the adjustment process and directly drive the support component to adjust and switch between different height positions. This design simplifies the structural design of the support component, makes it easier for the user to hold, and improves the user's operating experience.

[0023] The lifting groove is a through groove provided in the support base, and the lifting groove is exposed outside the support base to form part of the outer surface of the upper baking pan assembly or the lower baking pan assembly.

[0024] In this technical solution, the exposed lifting groove forms part of the exterior surface of the grill, allowing users to directly observe the movement of the support components through the exposed lifting groove, making operation more intuitive and convenient, and further reducing the difficulty of operation.

[0025] Two support bases are provided, and the two support bases are symmetrically distributed on two opposite sides of the upper baking pan assembly or the lower baking pan assembly; two support members are provided accordingly, and the two support members are symmetrically distributed on two opposite sides of the upper baking pan assembly or the lower baking pan assembly.

[0026] In this technical solution, the symmetrically distributed support bases and support components provide more even support for the upper baking pan assembly, better distributing and bearing its weight. This ensures stable support for the upper baking pan assembly at different heights, guaranteeing the stability and reliability of the cooking cavity's current height dimensions and improving cooking results. Furthermore, the symmetrically distributed support components allow users to operate both hands simultaneously to rotate the upper baking pan assembly relative to the lower baking pan assembly, adjusting the cooking cavity height. This ergonomic design enhances operational comfort and improves the user experience. Attached Figure Description

[0050] Example 1:

[0051] like Figures 1 to 6As shown, an adjustable cooking space grill includes an upper grill plate assembly 1 and a lower grill plate assembly 2. The upper grill plate assembly 1 can cover the lower grill plate assembly 2 and form a cooking cavity 3. The upper grill plate assembly 1 is provided with a support base 5 and a support member 6 movably disposed on the support base 5. The lower grill plate assembly 2 is provided with a top support surface 211 that abuts against the support member 6 vertically. The support base 5 is provided with a lifting groove, and at least two locking positions 53 at different heights are provided in the lifting groove. The support member 6 is provided with a positioning protrusion 62, which can be locked or disengaged from the locking positions 53. The support member 6 can move relative to the support base 5 in the vertical direction of the lifting groove to rise and fall to the locking positions 53 at different heights, and the support member 6 can move relative to the support base 5 in the horizontal direction to move to the locking position 53 corresponding to the current height.

[0052] In a specific implementation, such as Figures 3 to 6 As shown, the upper baking pan assembly 1 includes an upper cover 11 and an upper baking pan 12 disposed on the upper cover 11. The support base 5 is disposed on the upper cover 11 and protrudes laterally. The lower baking pan assembly 2 includes a base 21 and a lower baking pan 22 disposed on the base 21. The top support surface 211 is disposed on the base 21 and extends laterally.

[0053] In this embodiment 1, the support base 5 is provided with at least two locking positions 53 at different heights, and the support member 6 is provided with a positioning protrusion 62. The support member 6 can move relative to the support base 5 along the vertical and horizontal directions of the lifting groove, so that the positioning protrusion 62 can be locked or disengaged from the locking positions 53 at different heights, thereby realizing the adjustment of the height of the cooking cavity 3. In the entire operation process, the user only needs to operate the support member 6 itself to complete the lifting and lowering of different heights and the displacement of the corresponding locking positions 53. The operation is simple and convenient, and the position switching of one support member 6 can be completed with one hand without any other auxiliary actions. The operation is flexible and convenient, greatly improving the user experience. Especially in the case of multi-level adjustment, the user can easily and quickly adjust the height of the cooking cavity 3 by moving the support member 6 vertically and horizontally according to the thickness of the food, so as to avoid the food being over-compressed during the cooking process and ensure the cooking effect of the food. Furthermore, unlike the prior art which requires the force of a spring to maintain the support position of the support member 6, this embodiment 1 omits the use of a spring. The support member 6 is locked and positioned by the locking of the positioning protrusion 62 and the locking position 53, thereby avoiding the problem of positioning failure caused by spring failure and ensuring the stability and reliability of the support member 6 after position adjustment.

[0054] In this embodiment 1, the structural design of the positioning protrusion can adopt any of the following embodiments:

[0055] Implementation Method 1: This implementation method is not illustrated. In this implementation method, the positioning protrusion is a convex shaft provided on two opposite sides of the support member.

[0056] Implementation Method Two: (e.g.) Figure 7 and Figure 8 As shown, the support member 6 has a through hole 61 extending along its length, and the positioning protrusion 62 is a rotating shaft passing through the through hole 61. Furthermore, the lifting groove is a through groove provided in the support base 5, and the lifting groove is exposed outside the support base 5. During installation, the support member 6 can be placed into the support base 5 first, and then the rotating shaft can be inserted through the through groove and the through hole 61 to realize the installation of the support member 6 on the support base 5. This structural design facilitates the assembly between the support member 6 and the support base 5.

[0057] As a preferred embodiment of this Example 1, such as Figure 4 , Figure 6 and Figure 8 As shown, the lifting trough includes multiple horizontal troughs 51 arranged in the vertical direction and a vertical switching guide trough 52 connecting two adjacent horizontal troughs 51. A stop position 53 is provided in the horizontal trough 51. The support member 6 moves at least in the horizontal direction to switch from the stop position 53 to the vertical switching guide trough 52, and the support member 6 moves in the vertical direction along the vertical switching guide trough 52 to move from the outlet of one horizontal trough 51 to the inlet of another horizontal trough 51.

[0058] In this embodiment, the support member 6 can flexibly switch between different heights of the horizontal groove 51 and the vertical switching guide groove 52. This design allows the user to easily adjust the distance between the upper baking pan assembly 1 and the lower baking pan assembly 2 according to the thickness of the food and cooking needs, so that the height of the cooking cavity 3 matches the current food cooking needs. The locking position 53 in the horizontal groove 51 can provide a precise positioning point for the support member 6, ensuring that the support member 6 can be stably supported at each height position, thereby ensuring the stability of the upper baking pan assembly 1 during cooking and avoiding problems such as food being crushed or food splashing inside the grill due to the upper baking pan assembly 1 suddenly falling. Furthermore, the combination of the horizontal groove 51 and the vertical switching guide groove 52 further reduces the complexity of operation. Users only need to move the support member 6 horizontally to switch the positioning protrusion 62 from one locking position 53 to the vertical switching guide groove 52, and then move it along the vertical switching guide groove 52 to the entrance of another horizontal groove 51. By horizontally moving the support member 6, the positioning protrusion 62 can be displaced to the corresponding locking position 53 at the current height, thus achieving the switching of the cooking cavity 3 height. This design simplifies the operation steps and improves the user experience. In addition, multiple horizontal grooves 51 are arranged vertically, and the locking positions 53 are located within the horizontal grooves 51, making the entire height adjustment clearly visible. Users do not need to exert special attention during operation to adjust the height of the cooking cavity 3, further enhancing the convenience and efficiency of operation.

[0059] In this embodiment, the structural details of the horizontal groove and the locking position can adopt any of the following examples:

[0060] Example 1: Not illustrated in Example 1, in this example, both the upper and lower sidewalls of the horizontal groove extend in a straight line, and the locking position is located on the side of the horizontal groove away from the vertical switching guide groove. During operation, the support member can switch from the locking position to the vertical switching guide groove simply by moving horizontally.

[0061] Example 2: such as Figure 4 and Figure 6 As shown in Example 2, the locking position 53 is located on the side of the horizontal groove 51 away from the vertical switching guide groove 52. The upper and lower sidewalls of the end of the horizontal groove 51 away from the vertical switching guide groove 52 do not extend in a straight line, but are designed as a groove structure to fit the positioning protrusion 62. For example, when the positioning protrusion 62 is a rotating shaft with a circular cross-section, the upper and lower sidewalls of the end of the horizontal groove 51 away from the vertical switching guide groove 52 extend in an arc shape to fit the shape of the positioning protrusion 62, making it more stable when the positioning protrusion 62 is locked in the locking position 53. When it is necessary to switch the height position, the support member 6 first needs to make a small vertical movement along the extension shape of the groove structure. After the positioning protrusion 62 disengages from the locking position 53, the support member 6 can then move horizontally to switch from the horizontal groove 51 to the vertical switching guide groove 52.

[0062] As a preferred example of this embodiment, the lifting groove is provided with a guide structure for guiding the positioning protrusion 62 to switch between the horizontal groove 51 and the vertical switching guide groove 52. By providing a guide structure in the lifting groove, the positioning protrusion 62 can be ensured to switch smoothly and accurately between the horizontal groove 51 and the vertical switching guide groove 52, avoiding jamming or displacement during the switching process, thereby improving the accuracy and stability of the position adjustment of the support member 6. The guide structure allows the user to adjust the height of the support member 6 simply by following the guidance of the guide structure, without having to pay too much attention to the specific switching details, making the entire adjustment process simpler and faster. In addition, the guide structure can reduce friction and collision between the positioning protrusion 62 and the inner wall of the support groove, reducing the risk of damage caused by improper operation, thereby extending the service life of the support base 5 and the support member 6.

[0063] Preferably, such as Figure 4 and Figure 6As shown, the guiding structure includes a first guide portion 54 that guides the positioning protrusion 62 from the vertical switching guide groove 52 into the horizontal groove 51, and a second guide portion 55 that guides the positioning protrusion 62 from the horizontal groove 51 to the vertical switching guide groove 52. The first guide portion 54 is located on the upper side wall of the horizontal groove 51, and its extension line extends downward to enter the vertical switching guide groove 52. The second guide portion 55 is located on the lower side wall of the horizontal groove 51, and its extension line extends upward to enter the vertical switching guide groove 52. The first guide portion 54 and the second guide portion 55 are located on the upper and lower side walls of the horizontal groove 51, respectively, and their respective extension lines extend downward and upward to enter the vertical switching guide groove 52. This design ensures that the positioning protrusion 62 can smoothly transition along the first guide portion 54 and the second guide portion 55 when entering the horizontal groove 51 from the vertical switching guide groove 52 or switching from the horizontal groove 51 to the vertical switching guide groove 52, reducing jamming and friction. Furthermore, the design of the first guide part 54 and the second guide part 55 can precisely guide the movement path of the positioning protrusion 62, ensuring more accurate and stable switching between the horizontal groove 51 and the vertical switching guide groove 52, thereby improving the adjustment accuracy of the support member 6. In addition, the design of the first guide part 54 and the second guide part 55 allows the user to adjust the height of the support member 6 simply by following the guidance of the first guide part 54 and the second guide part 55, without having to pay too much attention to the specific switching details, making the entire adjustment process simpler and faster.

[0064] In this embodiment 1, the structural design of the support base and the support member can adopt any of the following embodiments:

[0065] Implementation Method 3: This implementation method is not illustrated. In this implementation method, the support base includes two opposing support blocks. The two support blocks cooperate to form a sliding groove for the support member to slide up and down. The bottom of the sliding groove is open, allowing the support member to extend out and abut against the top support surface. An open area is provided on the side of the two support blocks away from the upper baking tray assembly. The support member has a laterally protruding gripping part that extends from the open area, allowing the user to easily move the support member vertically and horizontally by operating the gripping part.

[0066] Implementation Method Four: (e.g.) Figure 7 and Figure 8As shown, the support base 5 includes two opposing support blocks 510. A first open area 511 is formed between one end of the two support blocks 510 for the support member 6 to extend out and abut against the top support surface 211. A second open area 512 is formed between the other ends of the two support blocks 510 for the support member 6 to be exposed. The support member 6 is exposed from the second open area 512 and has a first force-applying end 63. The width of the support member 6 is greater than the width of the top support surface 211 so that the support member 6 has an exposed second force-applying end 64 that is opposite to the position of the first force-applying end 63.

[0067] In this fourth embodiment, a second open area 512 is formed between the two support blocks 510 for the support member 6 to be exposed. The support member 6 is exposed from the second open area 512 and has a first force-applying end 63. The width of the support member 6 is greater than the width of the top support surface 211 so that the support member 6 has an exposed second force-applying end 64 that is opposite to the first force-applying end 63. This design makes it convenient for the user to hold the support member 6 directly through the first force-applying end 63 and the second force-applying end 64 during the adjustment process, and directly drive the support member 6 to achieve adjustment and switching of different height positions. This design simplifies the structural design of the support member 6, makes it convenient for the user to hold, and improves the user's operating experience.

[0068] In this embodiment 1, the structural design of the lifting trough can adopt any of the following embodiments:

[0069] Implementation Method 5: This implementation method 5 is not illustrated. In this implementation method 5, the lifting groove is a blind groove provided on the support base.

[0070] Implementation method six: such as Figure 7 and Figure 8 As shown, the lifting groove is a through groove provided in the support base 5, and the lifting groove is exposed outside the support base 5 to form part of the outer surface of the upper baking tray assembly 1 or the lower baking tray assembly 2.

[0071] In this sixth embodiment, the exposed lifting groove forms part of the exterior surface of the grill. Users can directly observe the movement of the support 6 through the exposed lifting groove, making the operation more intuitive and convenient, and further reducing the difficulty of operation.

[0072] In this embodiment 1, the number of support bases 5 and support members 6 is not limited. In one embodiment, a support base 5 is provided on one side of the upper baking tray assembly 1, and a support member 6 is provided at the support base 5. In another embodiment, such as Figure 2As shown, there are two support bases 5, symmetrically distributed on opposite sides of the upper baking pan assembly 1 or the lower baking pan assembly 2; correspondingly, there are two support members 6, symmetrically distributed on opposite sides of the upper baking pan assembly 1 or the lower baking pan assembly 2. The symmetrically distributed support bases 5 and support members 6 provide more even support for the upper baking pan assembly 1, better distributing and bearing its weight. This ensures stable support for the upper baking pan assembly 1 at different heights, guaranteeing the stability and reliability of the current height dimension of the cooking cavity 3 and improving the cooking effect. Furthermore, the symmetrically distributed support members 6 allow the user to operate both hands simultaneously to rotate the upper baking pan assembly 1 relative to the lower baking pan assembly 2, thereby adjusting the height of the cooking cavity 3. This makes the entire operation more ergonomic, improving operational comfort and enhancing the user experience.

[0073] Example 2:

[0074] This embodiment 2 is basically the same as embodiment 1 in structure and principle, the difference being:

[0075] like Figure 9 and Figure 10 As shown, in this embodiment 2, the lifting groove includes a plurality of vertical grooves 56 arranged alternately in the horizontal direction, and a horizontal switching guide groove 57 connecting two adjacent vertical grooves 56. The height of each vertical groove 56 is different. The locking position 53 is provided in the vertical groove 56. The support member 6 moves at least in the vertical direction to switch from the locking position 53 to the horizontal switching guide groove 57, and the support member 6 moves in the horizontal direction to move from the outlet of one vertical groove 56 to the inlet of another vertical groove 56.

[0076] In this embodiment 2, the combination of the vertical groove 56 and the horizontal switching guide groove 57 allows the support member 6 to flexibly switch between different height locking positions 53. This design allows users to easily adjust the distance between the upper baking pan assembly 1 and the lower baking pan assembly 2 according to the thickness of the food and cooking needs, so that the height of the cooking cavity 3 matches the current food cooking requirements. The locking positions 53 in the vertical groove 56 can provide precise positioning points for the support member 6, ensuring that the support member 6 can be stably supported at each height position, thereby ensuring the stability of the upper baking pan assembly 1 during cooking and avoiding problems such as food being crushed or food splashing inside the grill due to the upper baking pan assembly 1 suddenly falling. Furthermore, the combination of the vertical groove 56 and the horizontal switching guide groove 57 further reduces the complexity of operation. Users only need to move the support member 6 vertically to switch the positioning protrusion 62 from one of the locking positions 53 to the entrance of one of the horizontal switching guide grooves 57. Then, by moving the support member 6 horizontally, the positioning protrusion 62 can be moved to the corresponding locking position 53 at the current height, thereby realizing the switching of the height of the cooking cavity 3. This design simplifies the operation steps and improves the user experience.

[0077] As a preferred embodiment of this Example 2, the lifting groove is provided with a guide structure for guiding the positioning protrusion 62 to switch between the vertical groove 56 and the horizontal switching guide groove 57.

[0078] This embodiment, by setting a guide structure within the lifting groove, ensures that the positioning protrusion 62 smoothly and accurately switches between the vertical groove 56 and the horizontal switching guide groove 57, avoiding jamming or offset during the switching process, thereby improving the accuracy and stability of the support member 6's position adjustment. The guide structure allows users to adjust the height of the support member 6 simply by following its guidance, without needing to focus on specific switching details, making the entire adjustment process simpler and faster. Furthermore, the guide structure reduces friction and collision between the positioning protrusion 62 and the inner wall of the support groove, lowering the risk of damage due to improper operation, thus extending the service life of the support base 5 and the support member 6.

[0079] In a preferred example, such as Figure 10As shown, the guiding structure includes a third guide portion 58 that guides the positioning protrusion 62 from the horizontal switching guide groove 57 into the vertical groove 56, and a fourth guide portion 59 that guides the positioning protrusion 62 from the vertical groove 56 to the horizontal switching guide groove 57. The third guide portion 58 is located on the upper side wall of the horizontal switching guide groove 57, and its extension line extends upward to enter the vertical groove 56. The fourth guide portion 59 is located on the lower side wall of the vertical groove 56, and its extension line extends upward to enter the horizontal switching guide groove 57. This arrangement ensures that the positioning protrusion 62 can smoothly transition along the third guide portion 58 and the fourth guide portion 59 when entering the horizontal switching guide groove 57 from the vertical groove 56 or switching from the horizontal switching guide groove 57 to the vertical groove 56, reducing jamming and friction. Furthermore, the design of the third guide section 58 and the fourth guide section 59 can precisely guide the movement path of the positioning protrusion 62, ensuring more accurate and stable switching between the vertical groove 56 and the horizontal switching guide groove 57, thereby improving the adjustment accuracy of the support member 6. In addition, the design of the third guide section 58 and the fourth guide section 59 allows users to adjust the height of the support member 6 simply by following the guidance of the third guide section 58 and the fourth guide section 59, without having to pay too much attention to the specific switching details, making the entire adjustment process simpler and faster.

[0080] Furthermore, both the third guide section 58 and the fourth guide section 59 extend in an arc shape to guide the positioning protrusion 62, enabling it to switch very smoothly between the vertical groove 56 and the horizontal switching guide groove 57 without causing significant obstruction, thus improving the user experience.

[0081] Example 3:

[0082] The structure and principle of this embodiment 3 are basically the same as those of embodiment 1 or embodiment 2. The difference is that in this embodiment 3, the support base and support member are located on the lower baking pan assembly, and the top support surface is located on the upper baking pan assembly.
