Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to a grill. 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 grills being able to cook ingredients of varying thicknesses, some existing grills are designed such that, when the upper and lower grill pans are closed, the cooking space between them can be freely adjusted within a certain height range, thus enabling them to accommodate ingredients of different thicknesses.

[0004] Patent document CN221963461 U discloses a grill, including a lower grill plate assembly and an upper grill plate assembly hinged together to form a cooking cavity. The grill includes a lifting device for adjusting the height of the cooking cavity. The lifting device includes a connector on the lower grill plate assembly and a movable member on the connector. The movable member has a supporting position between the lower and upper grill plate assemblies and a clearance position outside the lower and upper grill plate assemblies. The movable member moves radially on the lower grill plate assembly to switch between the supporting and clearance positions, thereby changing the height of the cooking cavity. Specifically, the movable member includes a supporting surface that abuts against the upper grill plate assembly. Multiple steps are provided on the supporting surface, allowing adjustment of the cooking cavity height when the upper grill plate assembly is placed on different steps. In this technical solution, the steps on the supporting surface only serve to vertically support the upper grill plate assembly to adjust its height; the supporting surface itself and the steps do not provide lateral limiting for the upper grill plate assembly. In actual use, to facilitate the opening and closing of the upper grill pan assembly, a clearance is required between the left and right mating surfaces of the upper grill pan assembly's pivot and the lower grill pan assembly's pivot support. In other words, to meet specific cooking needs, the upper grill pan assembly needs to have lateral movement flexibility relative to the lower grill pan assembly. However, in the aforementioned technical solution, when the upper grill pan assembly is supported on different steps, the support surface lacks a structure to limit its lateral movement. This results in the upper grill pan assembly being partially supported on the step and partially suspended when closed, if it deviates to the intended position to the left or right. As user demands increase, the performance of grill pans is constantly improving. Existing grill pan assemblies... The components are no longer limited to partial rotation of less than or equal to 90° around the pivot axis; they can be further rotated to a flat state of nearly 180°, so that both the upper and lower baking pans can support and grill food. To achieve the large-angle opening and closing of the upper baking pan assembly, the pivots of the existing upper and lower baking pan assemblies, in addition to the conventional rotation function, also have a vertical floating function. The vertical floating means that when one side of the upper baking pan assembly is placed on the step and the other side is suspended, the suspended side of the upper baking pan will directly press on the food. On the one hand, this causes uneven heating of the food; on the other hand, when using the grill to cook food that needs to proof, the direct pressure of the upper baking pan will affect the proofing effect of the food, causing one side of the food to be flattened, ultimately affecting the shape and taste of the food. Utility Model Content

[0005] This application provides a grill, which, to meet the cooking needs of ingredients of different thicknesses, allows the upper grill pan to be supported at different heights to adjust the height of the cooking cavity between the upper and lower grill pans. However, to facilitate the adjustment of the height distance between the upper and lower grill pans, the upper grill pan is configured to move left and right relative to the lower grill pan. This causes the upper grill pan to easily detach from one of the height support positions during the left and right movement, resulting in the upper grill pan only being supported on one side, while the other side is suspended. The suspended side of the upper grill pan will directly press on the food, causing the food on that side to overheat, ultimately leading to uneven heating and poor proofing of the food. This application aims to solve the technical problems caused by the upper grill pan being suspended on one side.

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

[0007] A grill includes an upper grilling plate assembly and a lower grilling plate assembly hinged together, with a cooking cavity between the upper and lower grilling plate assemblies. It also includes a lifting device for adjusting the height of the cooking cavity. The lifting device is located on both sides of the grill in the direction of opening and closing the lid, allowing for height adjustment of the grill's sides. The lifting device on each side has at least one set of support positions of the same height, with a limiting portion on the side of each support position closest to the cooking cavity. Both sides of the upper or lower grilling plate assembly are supported on the support positions, and the limiting portions on both sides together limit the left and right movement of the upper grilling plate assembly.

[0008] The lifting device in this application allows for adjustable height of the grill's cooking cavity, enabling users to select the appropriate setting based on the thickness of the food being cooked. For example, a lower support setting can be selected for thin sandwiches, minimizing the gap between the upper and lower grill pans for even heating and reduced energy waste. Conversely, a higher support setting can be selected for thicker steaks or foods requiring proofing, ensuring sufficient space between the upper and lower grill pans to accommodate the food. This flexibility allows the grill to adapt to various food thicknesses, broadening its applicability.

[0009] This application provides a limiting part on the side of the support position near the cooking cavity. When the lifting device is adjusted to the expected support height, due to the presence of the limiting parts on both sides, during the process of closing the upper baking pan assembly downwards or during use after closing, when the upper baking pan assembly shifts to the left or right, the limiting parts on both sides can cooperate to limit the left and right movement of the upper baking pan assembly, keeping the upper baking pan assembly in the preset position and avoiding the problem of one side being suspended. This can effectively eliminate the problem of uneven torque of one-sided support, and also maintain a relatively balanced distance or contact area between the left and right sides of the upper baking pan assembly and the food, which helps to achieve uniform heating of the food and avoid the problem of one-sided excessive temperature and one-sided flattening of the food caused by one-sided contact with the food. Taking the process of closing the upper baking pan assembly as an example, if the upper baking pan assembly shifts to the left, the limiting part on the left lifting device cannot limit the leftward movement of the upper baking pan assembly. However, when the upper baking pan assembly shifts to the left, the limiting part on the right lifting device will be on the path of the upper baking pan assembly's leftward movement, thereby blocking the leftward movement of the upper baking pan assembly, preventing the upper baking pan assembly from shifting, and allowing the upper baking pan assembly to close to the preset position.

[0010] Furthermore, during the process of closing the upper baking pan assembly to the lower baking pan assembly, the presence of the side limiting parts can provide clear guidance for the left and right placement of the upper baking pan assembly. With the upper baking pan assembly having the flexibility to sway left and right, or even float up and down, the upper baking pan assembly can be quickly and rapidly closed to the expected position, realizing the correction of positional deviation. The operation is simple and convenient, which can greatly improve the user experience.

[0011] The lifting device includes a support member disposed on one of the upper baking pan assembly and the lower baking pan assembly, and a movable member disposed on the other of the two and capable of moving left and right, wherein the support stop is disposed on the movable member.

[0012] This technical solution utilizes the lateral movement of movable parts to support the upper baking pan assembly at different heights. Compared to other relatively complex movement methods such as lifting, rotating, etc., this solution allows for simultaneous operation by both hands. The left and right hands can simultaneously push the movable parts towards one side of the cooking cavity or pull them outwards, enabling simultaneous movement of the left and right movable parts. This quick and easy operation significantly enhances the user experience. Furthermore, the lateral movement of the movable parts is easier to control and position, ensuring the upper baking pan assembly is accurately supported at the desired height to better match the cooking needs of the ingredients. Moreover, compared to vertical lifting or other complex movement trajectories, the lateral movement of movable parts in this solution optimizes the spatial layout of the grill and the operational space requirements during the movement of the movable parts, resulting in a more compact overall structure and saving space in the kitchen or other usage areas. In addition, compared with other relatively complex motion methods, the lateral movement trajectory of the moving parts is relatively simple, and there is relatively less friction and wear between the moving parts. This means that during long-term use, the lifting device can maintain better performance and precision, reduce the number of failures and repairs caused by wear, and extend the service life of the grill.

[0013] The movable component has a supporting state that abuts against the support component to lift the upper baking pan assembly, and a disengaging state that is detached from the support component. In the disengaging state, the height space of the cooking cavity is minimized.

[0014] In this technical solution, the movable component has a supporting state for lifting the upper baking pan assembly and a clearance state detached from the supporting component. In the clearance state, the height space of the cooking cavity is minimized. In other words, although the movable component in the clearance state is not in contact with the supporting component, it still creates a height position for the upper baking pan assembly. However, at this position, the height space of the cooking cavity is minimized, making it suitable for cooking flat foods such as pancakes and sandwiches. This reduces the number of support positions required at different heights on the movable component, simplifying its design and reducing manufacturing costs. Furthermore, in the clearance state, the movable component is located beside the supporting component, and the movable components on both sides can cooperate to restrict the lateral movement of the upper baking pan assembly, thus preventing its offset.

[0015] The support stops are offset from each other along the moving direction of the movable component.

[0016] The staggered support positions in this technical solution provide multiple height settings within the limited length of the movable parts. This not only makes the entire lifting device more compact, reducing the overall size of the grill and making it easier to store, but also allows for flexible adjustment of the cooking cavity height according to the size of the food being cooked. This achieves efficient use of the cooking cavity space. When cooking small ingredients, the upper baking tray can be lowered to a lower height, reducing the height of the cooking cavity, increasing heat concentration, and speeding up cooking. Conversely, when cooking large ingredients, sufficient space is provided to accommodate them. The adjustment of the upper baking tray assembly's support height can occur before the upper baking tray assembly is closed onto the lower baking tray assembly, or during the cooking process after the upper baking tray assembly has been closed onto the lower baking tray assembly. If it is necessary to adjust the support height of the upper baking tray assembly during cooking based on the cooking status of the food, the staggered support positions on the movable parts in this technical solution can quickly respond to this need. Users can quickly move the movable parts to the appropriate position, switch to the desired height setting, and adjust the cooking status in a timely manner, thereby avoiding overcooking or undercooking of the food.

[0017] The lifting device also includes a limiting member for preventing the movable part from swaying left and right. One of the movable part and the limiting member is provided with a plurality of locking positions arranged at intervals in the left and right direction, and the other is provided with a telescopic member that can extend into or disengage from the locking positions. The number of locking positions is not less than the number of support positions.

[0018] Because the upper baking pan assembly can only switch between different support heights by moving laterally, if the moving part is accidentally touched during cooking, causing it to move left or right and deviate from the preset position, the support height of the upper baking pan assembly will change. This technical solution uses a limiting component to restrict the lateral movement of the moving part, preventing positional changes due to accidental touches and ensuring that the upper baking pan assembly is stably supported in the preset position. Furthermore, the cooperation between the locking position and the telescopic component in this technical solution provides clear positioning feedback. Users can clearly perceive whether the moving part has accurately reached the required support level by touch, providing explicit guidance and improving the accuracy and convenience of operation. In addition, the number of locking positions in this technical solution is no less than the number of support levels, meaning that each support level has a corresponding locking position, ensuring that the upper baking pan assembly is stably supported at every support level. This allows for precise control of the distance between the upper and lower baking pan assemblies, achieving precise control of the cooking space and improving cooking results.

[0019] The limiting member has a fulcrum surface, and the fulcrum surface has a gripping position.

[0020] Because the movable component needs to be moved left and right to switch the support positions of the upper baking tray assembly at different heights, this technical solution incorporates a fulcrum surface on the limiting component. This allows some fingers of the user's hand to grip the fulcrum surface during the movement of the movable component, while the thumb pushes the component left and right. This facilitates user operation. The gripping design on the fulcrum surface provides a clear operating position, allowing the user to easily insert their fingers and apply force to move or adjust the movable component, preventing hand slippage. This ergonomic design enhances user comfort and reduces fatigue, improving the overall user experience. Furthermore, the gripping area makes the entire operation more intuitive, allowing users to clearly feel the operating position, reducing blind operation and improving efficiency.

[0021] The lifting device includes a support member disposed on one of the upper baking pan assembly and the lower baking pan assembly, and a movable member disposed on the other of the two and capable of moving up and down, wherein the support stop is disposed on the movable member.

[0022] In this technical solution, the movable component moves vertically, occupying primarily vertical space. This helps reduce the horizontal dimensions of the grill and the required horizontal operating space, making it particularly suitable for kitchens with limited horizontal space. Furthermore, the vertically movable component can quickly change the support height of the upper grill pan assembly, responding promptly to height adjustment needs.

[0023] The movable component is provided with a force-applying surface, and the force-applying surface is provided with an anti-slip structure.

[0024] In a kitchen environment, users' hands are easily exposed to water or grease. This technical solution addresses this by incorporating an anti-slip structure on the force-bearing surface of the moving parts. This increases the friction between the hand and the surface, effectively preventing hand slippage during operation. This allows users to control the moving parts more stably and accurately, avoiding the drawback of slippage preventing operation. Furthermore, by increasing the friction and contact stability between the hand and the surface, users can more precisely control the speed and position of the moving parts, achieving finer height adjustments to meet diverse cooking needs.

[0025] The lifting device has a support member that can stop with the limiting part, and the length dimension of the support stop in the left-right direction is greater than the thickness dimension of the support member in the left-right direction.

[0026] This technical solution uses a support member to abut and limit the upper baking pan assembly relative to the lower baking pan assembly, preventing it from detaching from the support position on one side during left-right swaying. By setting the thickness of the support member in the left-right direction to be smaller than the length of the support position in the left-right direction, the upper baking pan assembly can still have a certain amount of swaying space relative to the lower baking pan assembly. This facilitates opening and closing the lid and allows the upper baking pan assembly to be lifted smoothly during cooking, preventing the food from being flattened during the proofing process and affecting the proofing effect.

[0027] The lifting device includes a support member and a movable member that can move relative to the support member. The support stop is located on the movable member. The support member is located on the upper baking pan assembly. The lower baking pan assembly includes a base and a lower baking pan that can be removed from the base. The movable member is mounted on the lower baking pan and protrudes laterally from the lower baking pan, such that the movable member constitutes at least part of the end handle of the lower baking pan.

[0028] In this technical solution, the movable part protrudes laterally from the lower baking pan, and the movable part constitutes at least part of the handle at the end of the lower baking pan. This design eliminates the need for an external handle or operating component. When it is necessary to remove the lower baking pan from the base, the lower baking pan can be lifted by directly holding the movable part. This realizes the functional integration of the movable part, simplifies the design of the grill, and makes the overall structure of the grill more compact. Attached Figure Description

[0051] Example 1:

[0052] like Figures 1 to 6 As shown, a grill includes an upper grilling plate assembly 1 and a lower grilling plate assembly 4 hinged together, with a cooking cavity 5 between the upper grilling plate assembly 1 and the lower grilling plate assembly 4. It also includes a lifting device for adjusting the height of the cooking cavity. The lifting device is located on both sides of the grill in the direction of opening and closing the lid, allowing for height adjustment of the two sides of the grill. The lifting devices on both sides are provided with at least one set of support positions 22 of the same height. Each support position 22 has a limiting part 21 on the side closest to the cooking cavity 5. Both sides of the upper grilling plate assembly 1 or the lower grilling plate assembly 4 are supported on the support positions 22, and the limiting parts 21 on both sides together limit the left and right movement of the upper grilling plate assembly 1.

[0053] The lifting device in this embodiment 1 allows for adjustable height of the cooking cavity 5 of the grill, enabling users to select the appropriate setting based on the thickness of the food being cooked. For example, for thin sandwiches, a lower support setting 22 can be selected to minimize the gap between the upper grill plate assembly 1 and the lower grill plate assembly 4, ensuring even heating and reducing energy waste. Conversely, for thicker steaks or foods requiring proofing, a higher support setting 22 can be selected to ensure sufficient space between the upper and lower grill plate assemblies 1 and 4 to accommodate the food. This flexibility allows the grill to adapt to various food thicknesses, broadening its applicability.

[0054] In this embodiment 1, a limiting part 21 is provided on the side of the support position 22 near the cooking cavity 5. When the lifting device is adjusted to the expected support height, due to the presence of the limiting parts 21 on both sides, when the upper baking pan assembly 1 is offset to the left or right during the process of closing the upper baking pan assembly 1 or during use after closing, the limiting parts 21 on both sides can cooperate with each other to limit the left and right movement of the upper baking pan assembly 1, so that the upper baking pan assembly 1 is kept in the preset position, avoiding the problem of one side being suspended. This can effectively eliminate the problem of unbalanced torque of one-sided support, and also make the left and right sides of the upper baking pan assembly 1 maintain a relatively balanced distance or contact area with the food, which helps to achieve uniform heating of the food and avoid the problem of one-sided excessive temperature and one-sided flattening of the food caused by one-sided contact with the food. Taking the process of closing the upper baking pan assembly 1 and the upper baking pan assembly 1 shifting to the left as an example, the limiting part 21 on the left lifting device cannot limit the leftward movement of the upper baking pan assembly 1. However, when the upper baking pan assembly 1 shifts to the left, the limiting part 21 on the right lifting device will be on the moving path of the upper baking pan assembly 1 to the left, thereby blocking the leftward movement of the upper baking pan assembly 1, preventing the upper baking pan assembly 1 from shifting, and enabling the upper baking pan assembly 1 to close to the preset position.

[0055] Furthermore, during the process of closing the upper baking pan assembly 1 to the lower baking pan assembly 4, the presence of the side limiting parts 21 can provide clear guidance for the left and right placement of the upper baking pan assembly 1. With the flexibility of the upper baking pan assembly 1 to swing left and right, or even float up and down, the upper baking pan assembly 1 can be quickly and rapidly closed to the expected position, realizing the correction of positional deviation. The operation is simple and convenient, which can greatly improve the user experience.

[0056] like Figure 2 , Figure 4 and Figure 6As shown in Embodiment 1, the lifting device includes a support member 13 located on the upper baking pan assembly 1 and a movable member 2 located on the lower baking pan assembly 4 that can move laterally left and right. The support position 22 is located on the movable member 2. Alternatively, the support member 13 can be located on the lower baking pan assembly 4, and the movable member 2 on the upper baking pan assembly 1. The left and right lateral movement of the movable member 2 allows for support at different heights on the upper baking pan assembly 1. Compared to other relatively complex movements such as lifting, rotating, etc., the left and right hands can operate simultaneously during operation. That is, the left and right hands can simultaneously push the movable member 2 towards one side of the cooking cavity 5 or simultaneously pull the movable member 2 outwards, achieving simultaneous movement of the left and right movable members. This operation is quick and easy, greatly improving the user experience. Furthermore, the left and right lateral movement of the movable member 2 is easier to control and position, ensuring that the upper baking pan assembly 1 can be accurately supported at the expected height support position 22 to better match the cooking requirements of the ingredients. Furthermore, compared to vertical lifting or other complex motion trajectories, the lateral movement of the movable part 2 in this embodiment 1 can optimize the spatial layout of the grill to a certain extent, as well as the operating space requirements during the movement of the movable part 2. This makes the overall structure of the grill more compact and saves space in the kitchen or usage area. In addition, compared to other relatively complex motion methods, the lateral movement trajectory of the movable part 2 is relatively simple, and there is relatively less friction and wear between moving parts. This means that during long-term use, the lifting device can maintain better performance and precision, reduce the number of failures and repairs caused by wear, and extend the service life of the grill.

[0057] Taking the example of the support member 13 being located on the upper baking pan assembly 1 and the movable member 2 being located on the lower baking pan assembly 4, this embodiment 1 will be further described in detail. Figure 7 , Figure 8 , Figure 9 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 member 13 is a rib provided on the side of the upper cover 11. The movable member 2 is provided laterally protruding from the lower baking pan assembly 4. The limiting part 21 is a protrusion provided on the side of each support position 22 near the cooking cavity 5. Preferably, the support member 13 is provided with a guide slope 131, and the limiting part 21 is provided with a matching slope 211, so that the support member 13 can be smoothly inserted into the support position 22.

[0058] In this embodiment 1, the cooperation method between the movable part and the support part can be any one of the following embodiments:

[0059] Implementation Method 1: This implementation method is not illustrated. In this implementation method, the movable component has multiple support positions of different heights, such as two, three, four, or even more. When the upper baking pan assembly is closed onto the lower baking pan assembly, the movable component abuts against the support component at each height position, thereby supporting the upper baking pan assembly.

[0060] Implementation Method Two: (e.g.) Figure 1 , Figure 3 and Figure 5 As shown, in this second embodiment, the movable member 2 has a supporting state in which it abuts against the support member 13 to lift the upper baking pan assembly 1, and a yielding state in which it is disengaged from the support member 13. In the yielding state, the height space of the cooking cavity 5 is minimized.

[0061] In this second embodiment, the movable component 2 has a supporting state for lifting the upper baking pan assembly 1 and a clearance state for disengaging from the support component 13. In the clearance state, the height space of the cooking cavity 5 is minimized. In other words, although the movable component 2 in the clearance state does not contact the support component 13, it still creates a height position for the upper baking pan assembly 1. However, at this position, the height space of the cooking cavity 5 is minimized, which is suitable for cooking some flat foods, such as pancakes and sandwiches. This reduces the number of support positions 22 at different height positions on the movable component 2, which helps to simplify the design of the movable component 2 and reduce processing and manufacturing costs. Moreover, in the clearance state, the movable component 2 is located beside the support component 13. The movable components on the left and right sides can also restrict the left and right movement of the upper baking pan assembly 1 by cooperating with each other, thereby preventing the upper baking pan assembly 1 from shifting.

[0062] Specifically, the structural design of the moving part in this second embodiment can adopt any of the following examples:

[0063] Example 1: Not illustrated in Example 1, this example features only one support position on the movable component. When the movable component moves to a clearance state, disengaging from the support, the upper baking pan assembly is not supported at the support position, resulting in the minimum height of the cooking cavity. When the movable component moves to abut against the support, the upper baking pan assembly is supported at the single support position, raising its height and expanding the height of the cooking cavity. This example 1 provides two levels of height adjustment for the cooking cavity.

[0064] Example 2: In this Example 2, the movable part 2 has two support positions, and the two support positions are at different heights. For example... Figure 1 and Figure 2 As shown, when the movable part 2 moves to the avoidance state where it is disengaged from the support part 13, the upper baking tray assembly 1 is not supported at the support position 22, and the height space of the cooking cavity 5 is at its minimum. Figure 3 and Figure 4As shown, when the movable part 2 moves laterally toward the side closer to the cooking cavity 5, so that the upper baking pan assembly 1 is supported on one of the support positions 22 with a relatively low position height, the height space of the cooking cavity 5 is expanded; as Figure 5 and Figure 6 As shown, when the movable part 2 continues to move laterally towards the side closer to the cooking cavity 5, so that the upper baking pan assembly 1 is supported on the other support position 22 with the highest position, the height space of the cooking cavity 5 is further expanded. This example 2 realizes three-level adjustment of the height space of the cooking cavity 5. Of course, similar to this example 2, in other examples, the movable part 2 can also be provided with three, four or even more support positions 22 with different positions and heights to realize more levels of adjustment of the height of the cooking cavity 5.

[0065] Regardless of whether it is the first or the second implementation method, the support positions 22 can be further offset from each other along the moving direction of the movable member 2. The offset support positions 22 can provide multiple height positions within the limited length of the movable member 2, which not only makes the structure of the entire lifting device more compact, helps to reduce the overall size of the grill, and makes the grill easier to store, but also allows for flexible adjustment of the height of the cooking cavity 5 according to the size of the food to be cooked, achieving efficient use of the space of the cooking cavity 5. When cooking small food items, the upper baking tray 12 can be lowered to a lower height, reducing the height of the cooking cavity 5, increasing the heat concentration, and speeding up the cooking speed. When cooking large food items, sufficient space can be provided to accommodate the food. The adjustment of the support height of the upper baking pan assembly 1 can occur before the upper baking pan assembly 1 is closed onto the lower baking pan assembly 4, or it can occur during the cooking process after the upper baking pan assembly 1 has been closed onto the lower baking pan assembly 4. If it is necessary to adjust the support height of the upper baking pan assembly 1 according to the cooking status of the ingredients during the cooking process, the mutually staggered support positions 22 on the movable part 2 in this technical solution can quickly respond to this need. Users can quickly move the movable part 2 to the appropriate position, switch to the required height position, and adjust the cooking status in time, thereby avoiding the situation of over-baking or under-baking of food.

[0066] Specifically, the arrangement of the support gears can adopt any of the following examples:

[0067] Example 3: such as Figure 2 , Figure 4 , Figure 6 and Figure 9As shown, multiple support positions 22 are arranged in a stepped pattern along the left-right lateral movement direction of the movable part 2. The height of each support position 22 increases sequentially from the side closer to the cooking cavity 5 to the side farther away from the cooking cavity 5. When the movable part 2 moves left-right, the support 13 moves along the surface of the movable part 2. When it moves to a support position 22 of different heights, the support 13 is supported by the corresponding step, thereby realizing the switching of the upper baking pan assembly 1 at different height positions.

[0068] Example 4: Not illustrated in Example 4, this example features multiple layers of staggered support positions on the movable component. The height of each support position increases sequentially from the side closest to the cooking cavity to the side furthest from the cooking cavity, and they are staggered along the left-right direction. When the movable component moves laterally left and right, the upper baking pan assembly can be supported sequentially on different layers of support positions, thereby achieving smooth switching of the upper baking pan assembly at different height positions.

[0069] Example 5: Not illustrated in Example 5, the surface of the movable part facing the cooking cavity is designed as an inclined surface. Multiple support positions are respectively set on the inclined surface and distributed sequentially along the longitudinal direction of the inclined surface, so that the height of each support position gradually changes as the inclined surface extends longitudinally. When the movable part moves left or right, the support moves along the inclined surface. When the support moves to different support positions, the upper baking tray assembly is raised or lowered to the corresponding height, thereby realizing the switching of the upper baking tray assembly at different height positions.

[0070] Because the upper baking pan assembly 1 can only switch between different support height positions by the lateral movement of the movable part 2, if the movable part 2 is accidentally touched under the action of external force during the cooking process, causing it to continue to move to the left or right and deviate from the preset position, the support height of the upper baking pan assembly 1 will change. Therefore, as a preferred embodiment of this example 1, as... Figure 2 , Figure 4 and Figure 6As shown, the lifting device also includes a limiting member 3 to prevent the movable part 2 from swaying left and right. The movable part 2 has multiple locking positions 23 spaced apart in the left and right direction. The limiting member 3 has a telescopic member that can extend into or disengage from the locking positions 23. The number of locking positions 23 is not less than the number of support positions 22. Of course, it can also be the other way around, with multiple locking positions 23 spaced apart in the left and right direction on the limiting member 3, and a telescopic member that can extend into or disengage from the locking positions 23 on the movable part 2. By setting the limiting member 3, the displacement of the movable part 2 can be restricted from swaying left and right, avoiding changes in the position of the movable part 2 due to accidental touch, thereby ensuring that the upper baking tray assembly 1 can be stably supported in the preset position. Moreover, the cooperation between the locking positions 23 and the telescopic member can provide clear positioning feedback. Users can clearly perceive by hand whether the movable part 2 has accurately reached the required support position 22, realizing explicit guidance and improving the accuracy and convenience of operation. In addition, the number of locking positions 23 is no less than the number of support positions 22, which means that each support position 22 will have a corresponding locking position 23, so that the upper baking pan assembly 1 can be stably supported on each support position 22, thereby accurately controlling the distance between the upper baking pan assembly 1 and the lower baking pan assembly 4, achieving precise control of the cooking space, and improving the cooking effect.

[0071] like Figure 1 and Figure 2 As shown, taking the above-mentioned movable part 2 having a supporting state that abuts against the support member 13 to lift the upper baking pan assembly 1, and a clearance state that is disengaged from the support member 13 as an example, the number of locking positions 23 is greater than the number of supporting positions 22; in the clearance state, the telescopic member extends into the locking position 23 closest to the cooking cavity 5, thereby restricting the left and right movement of the movable part 2 in the clearance state, so that the movable part 2 can be stably kept in the clearance state, thereby so that the upper baking pan assembly 1 is stably kept in the lowest state of covering the lower baking pan assembly 4.

[0072] In a specific example, such as Figure 2 , Figure 4 and Figure 6 As shown, the telescopic component includes a telescopic rod 31 and an elastic element 32 for pushing the telescopic rod 31 into the locking position 23. The limiting member 3 has a cavity 35 adapted to the telescopic rod 31, and the telescopic rod 31 extends and retracts along the cavity 35 to extend into or disengage from the locking position 23. The elastic element 32 may be, for example, a spring. The locking position 23 may be, for example, a recess.

[0073] As a preferred example of this embodiment, the lifting device further includes a guide structure for guiding the left and right movement of the movable member 2. The guide structure includes a guide protrusion provided on one of the limiting member 3 and the movable member 2, and a guide groove provided on the other. The guide structure guides the left and right lateral movement of the movable member 2, allowing the movable member 2 to slide smoothly along a preset trajectory, thereby helping the telescopic member and the locking position 23 to be smoothly locked in the preset position.

[0074] As a preferred example of this implementation, such as Figure 4 and Figure 6 As shown, the limiting member 3 has a fulcrum surface 33, and a gripper 34 is provided on the fulcrum surface 33. Because the movable part 2 needs to be pushed left and right to switch the support positions 22 of the upper baking pan assembly 1 at different heights, this example uses a fulcrum surface 33 on the limiting member 3. This allows some fingers of the user's hand to grip the fulcrum surface 33 during the pushing of the movable part 2, while the user's thumb pushes the movable part 2 left and right, facilitating user operation. The gripper 34 on the fulcrum surface 33 provides a clear operating position for the user, allowing them to easily insert their fingers and apply force to move or adjust the movable part 2, preventing hand slippage. This design is more ergonomic, making the user more comfortable when operating the movable part 2, reducing fatigue, and improving the user experience. Furthermore, the gripper 34 makes the entire operation more intuitive, allowing the user to clearly touch the operating position, reducing blind operation and improving efficiency.

[0075] As another preferred example (not shown) of this embodiment, the limiting member has a fulcrum surface, and a first anti-slip structure is provided on the fulcrum surface. The first anti-slip structure may be, for example, a relatively rough frosted surface, an uneven anti-slip texture, etc.

[0076] As a preferred embodiment of this Example 1, such as Figure 2 and Figure 4 As shown, the movable part 2 has a force-applying surface 24, and a second anti-slip structure 25 is provided on the force-applying surface 24. The second anti-slip structure can be, for example, a relatively rough frosted surface or an uneven anti-slip texture. In a kitchen environment, the user's hands are easily exposed to water or grease. This embodiment increases the friction between the hand and the force-applying surface 24 by providing an anti-slip structure on the movable part 2, effectively preventing hand slippage during operation. This allows the user to control the movable part 2 more stably and accurately, avoiding the drawback of the movable part 2 becoming unoperable due to slippage. Moreover, by increasing the friction and contact stability between the hand and the force-applying surface 24, the user can more precisely control the movement speed and position of the movable part 2, achieving more precise height adjustment to meet different cooking needs.

[0077] As a preferred embodiment of this Example 1, such as Figure 2 , Figure 4 and Figure 6 As shown, the lifting device has a support member 13 that can stop against the limiting part 21. The length dimension of the support position 22 in the left-right direction is greater than the thickness dimension of the support member 13 in the left-right direction. The support member 13 achieves the abutment and limiting of the limiting part 21 to prevent the upper baking pan assembly 1 from detaching from the support position 22 on one side during the left-right swaying process relative to the lower baking pan assembly 4. By setting the thickness dimension of the support member 13 in the left-right direction to be smaller than the length dimension of the support position 22 in the left-right direction, the upper baking pan assembly 1 can still have a certain amount of left-right swaying margin relative to the lower baking pan assembly 4. On the one hand, this facilitates opening and closing the lid. On the other hand, for foods that need to proof during frying or grilling, the upper baking pan assembly 1 can be lifted smoothly during the cooking process to prevent the food from being flattened during proofing and affecting the proofing effect.

[0078] The location and arrangement of the support and movable parts in this embodiment 1 can be any one of the following embodiments:

[0079] Embodiment Three: This embodiment three is not illustrated. In this embodiment three, the support member is provided on the lower baking pan assembly. The upper baking pan assembly includes a top cover and an upper baking pan that can be removed and placed from the top cover. The movable member is installed on the upper baking pan and protrudes laterally from the upper baking pan, so that the movable member constitutes at least part of the handle for removing and placing the upper baking pan. In this embodiment one, the movable member is directly used as the operating handle for removing and placing the upper baking pan, which eliminates the need for a separate handle design.

[0080] Implementation Method Four: (e.g.) Figure 1 , Figure 3 and Figure 5 As shown, the support member 13 is provided on the upper baking pan assembly 1, and the lower baking pan assembly 4 includes a base 41 and a lower baking pan 42 that can be removed and placed from the base 41. The movable member 2 is installed on the lower baking pan 42 and protrudes laterally from the lower baking pan 42, so that the movable member 2 constitutes at least part of the end handle of the lower baking pan 42. In this fourth embodiment, the movable member 2 protrudes laterally from the lower baking pan 42, and the movable member 2 constitutes at least part of the end handle of the lower baking pan 42. This design eliminates the need for an external handle or operating component. When it is necessary to remove the lower baking pan 42 from the base 41, the lower baking pan 42 can be lifted by directly holding the movable member 2. This realizes the functional integration of the movable member 2, simplifies the design of the grill, and makes the overall structural layout of the grill more compact.

[0081] Embodiment Five: This embodiment five is not illustrated. A support member is located on the upper baking pan assembly. The lower baking pan assembly includes a base and a lower baking pan that can be removed from the base. A movable member is mounted on the base and protrudes laterally from the base, so that the movable member constitutes at least part of the end handle of the base. This embodiment five, by placing the movable member on the base and using it as an end handle for lifting the base, eliminates the need for a separate handle design. The entire grill can be lifted simply by gripping the movable member, achieving multi-functionality and integration.

[0082] Example 2:

[0083] The structure and principle of this embodiment 2 are basically the same as those of embodiment 1, except that the moving parts move in a different way.

[0084] This embodiment 2 is not illustrated. In this embodiment 2, the lifting device includes a support member disposed on one of the upper baking pan assembly and the lower baking pan assembly, and a movable member disposed on the other of the two that can be lifted up and down. The support position is disposed on the movable member.

[0085] In this embodiment 2, the movable component moves in a vertical lifting manner, primarily occupying space in the vertical direction. This helps reduce the horizontal dimensions of the grill and the required horizontal operating space, making it particularly suitable for kitchens with limited horizontal space. Furthermore, the vertically lifting movable component can quickly change the support height of the upper grill plate assembly, responding promptly to height adjustment needs.

[0086] In an example not shown, the support component is located on the upper baking pan assembly, and the movable component is located on the lower baking pan assembly. The lower baking pan assembly also has a connector for mounting the movable component. The movable component includes a movable rod and a support platform mounted on the movable rod. The movable component has a support stop, and the movable rod has external threads along its axial direction. The connector has a threaded hole adapted to the movable rod. By rotating the movable rod, the height of the support platform can be changed, thereby adjusting the height of the cooking cavity. Of course, a similar approach can be used, placing the support component on the lower baking pan assembly and the movable component on the upper baking pan assembly.

[0087] In another example not shown, a support member is located on the upper baking pan assembly, and a movable member is located on the lower baking pan assembly. The lower baking pan assembly is also provided with a connector for mounting the movable member. The movable member includes a movable block with a top support ramp at its top. The top support ramp has multiple support positions along its extension direction. The movable block is vertically mounted on the connector. As the movable block rises and falls, the support member is supported to different support positions on the top support ramp, thereby adjusting the height of the cooking cavity.
