Description

Technical Field

[0001] This invention relates to the field of cooking appliances, and more specifically, to a grill. Background Technology

[0002] In related technologies, when a grill is heating food, the upper lid comes into contact with and presses on the food. This pressing tendency can damage some types of food, thus affecting the quality of the final food and ruining the user experience.

[0003] Therefore, designing a grill that can overcome the above-mentioned technical defects has become an urgent technical problem to be solved. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, the present invention proposes a grilling machine.

[0006] In view of this, the present invention provides a grill, the grill comprising: a first housing; a second housing movably connected to the first housing; a support assembly disposed on the second housing, the support assembly comprising: a telescopic member connected to the second housing; and a cam mechanism that, when the cam mechanism moves, can drive the telescopic member to move, so as to adjust the distance between the first housing and the second housing.

[0007] This application defines a grill for heating food. Specifically, the grill includes a first housing and a second housing, which are two main structures on the grill and are arranged opposite to each other in the height direction of the grill. The lower housing is used to support and heat food, while the upper housing is used to position and heat food. This technical solution does not impose rigid limitations on the specific functions of these two housings; meeting the structural positional relationship and basic heating requirements is sufficient.

[0008] In related technologies, when cooking appliances with separate top and bottom shells heat food, the weight of the top shell presses the food down onto the bottom shell. However, when heating delicate foods that need to maintain their original shape, the pressure of the top shell can have a counterproductive effect, causing the food to be squeezed, deformed, or even broken. For example, when heating egg tarts or buns with a pressure-type cooking appliance, the pressing top shell can squeeze out the filling. Similarly, when heating crispy foods like pancakes or cookies with a pressure-type cooking appliance, the pressing top shell can crush the food. Therefore, it is clear that these technologies suffer from the problem of food being easily crushed.

[0009] In this application, the grill is further provided with a support assembly. This support assembly is mounted on the second housing and contacts the first housing. The support assembly can adjust the distance between the first and second housings through structural support, thereby adjusting the spacing between the upper and lower housing structures of the grill. Specifically, the support assembly includes a telescopic member and a cam mechanism. The telescopic member is mounted on the second housing and can move relative to the second housing to extend outside or retract into it. The cam mechanism is mounted on the second housing and includes an action surface whose position changes relative to the second housing during rotation. During movement, this action surface can abut against the telescopic member.

[0010] During operation, adjusting the position of the cam mechanism's working surface can push the telescopic component relative to the second housing. If the second housing is positioned on top of the first housing, the extended telescopic component can lift the second housing, increasing the distance between the second and first housings. Conversely, if the second housing is positioned at the bottom of the first housing, the extended telescopic component can lift the first housing, similarly adjusting the distance between the first and second housings.

[0011] This allows users to adjust the distance between the first and second shells to a range greater than or equal to the height of the food when heating foods that require shaping or have a crisp texture, by manipulating the support assembly. This prevents the upper shell from pressing down on the food. For example, when heating buns or pancakes using the grill as defined in this application, the support assembly can be manipulated to create a gap between the top shell and the bun or pancake, preventing the top shell from pressing out the filling or crushing the pancake. This solves the technical problems of food damage, limited range of heated foods, and poor user experience in the aforementioned related technologies. It optimizes the grill's structure, improves its operability, expands its functional range, ensures the quality of heated food, and enhances the user experience.

[0012] In addition, the dining table provided by the present invention may also have the following additional technical features:

[0013] In the above technical solution, the second housing includes a through hole, and the telescopic member includes a support portion corresponding to the through hole. When the cam mechanism rotates to a first angle, at least a portion of the support portion passes through the through hole and contacts the first housing, with the first housing and the second housing spaced apart by a first distance. When the cam mechanism rotates to a second angle, the first housing and the second housing are spaced apart by a second distance. In this technical solution, a cavity and a through hole connecting the cavity and the external space are formed on the second housing. When the first housing and the second housing are in a snap-fit ​​state, the through hole faces the direction of the first housing. Based on this, the structure of the telescopic member is further described. Specifically, the telescopic member includes a support portion, and the shape of the through hole is adapted to the outer contour shape of the support portion so that the support portion can move along the axial direction of the through hole. During the movement of the cam mechanism, the support portion abuts against the working surface on the cam mechanism.

[0014] In this cam mechanism, the radial distance between different areas on the working surface and the rotation axis varies. During rotation, the working surface rotates around the rotation axis, causing the distance between the working surface abutting the support and the rotation axis to change. When this distance increases, the support is pushed out of the through-hole by the cam mechanism. Conversely, when this distance decreases, the support can be reset by gravity or elasticity, retracting into the through-hole. This optimizes the telescopic component structure, improves the operability of the grill, and enhances the quality of the heated food.

[0015] Specifically, the cam mechanism has two critical angles: a first angle and a second angle.

[0016] When the cam mechanism rotates to the first angle, the radial distance between the working surface abutting the support and the rotation axis is the maximum value of the entire rotation stroke, corresponding to the longest extension distance of the support relative to the through hole. At this time, the support can lift the first or second housing located at the top, so that the first housing and the second housing are separated by a first distance to avoid the food being squeezed by the housing.

[0017] When the cam mechanism rotates to the second angle, the radial distance between the working surface abutting the support and the rotation axis is the minimum value of the entire rotation stroke. At this time, the support retracts into the cavity, or the lower section of the support is flush with the bottom surface of the second housing. At this time, the first housing and the second housing are separated by a second distance.

[0018] It is worth noting that the first distance is greater than the second distance, and the second distance can be greater than or equal to 0.

[0019] Based on the user's actual cooking needs using the grill, the distance between the first and second housings is controlled by rotating the cam mechanism. For example, when cooking foods that shouldn't be squeezed, such as buns or pancakes, a first distance can be maintained between the first and second housings to prevent them from squeezing the food. When cooking thinner, more easily squeezed foods, such as meat, a second distance can be maintained between the first and second housings to reduce the contact area between the food and air.

[0020] In any of the above technical solutions, the telescopic component further includes: an elastic component, which is sleeved on the support portion; wherein, when the cam mechanism rotates to the first angle, the elastic component undergoes elastic deformation, and when the cam mechanism rotates to the second angle, the elastic component drives the support portion to reset.

[0021] In this technical solution, the telescopic component also includes an elastic element, which is fitted onto the support portion. When the cam mechanism rotates to a first angle, the deformation of the elastic element is minimal. At this point, the elastic element can overcome the weight of the telescopic component, allowing it to stop in the retracted position. When the cam mechanism is rotated out of the first angle, the action surface on the cam presses against the support portion in the direction of the first housing, causing the support portion to move in that direction. The support portion extends out of the through hole, and the elastic element is compressed by the support portion. After the operation on the cam is removed, the elastic element releases its elastic potential energy, pushing the support portion away from the first housing. This completes the automatic reset of the telescopic component, thereby improving its operability and providing convenience for the user.

[0022] Specifically, the elastic element can be a spring. The spring is sleeved around the periphery of the support portion, with one end of the spring abutting against the second housing near the through hole and the other end abutting against the support portion. After the cam mechanism rotates to the first angle, the spring is compressed; conversely, after the operation is removed, the compressed spring will spring the support portion back to its initial position.

[0023] The elastic element can also be an elastic retaining ring filled between the connecting part and the second housing. After the cam mechanism rotates to the first angle, the elastic retaining ring is compressed and deformed. Conversely, after the operation is removed, the compressed and deformed elastic retaining ring will spring the support back to the initial position.

[0024] In addition, the elastic element can also be a component composed of various elastic structures. This technical solution does not impose any rigid restrictions on this, as long as it meets the automatic reset requirement.

[0025] In any of the above technical solutions, a first limiting part for axially limiting the elastic element is provided in the through hole; a second limiting part for axially limiting the elastic element is provided in the support part away from the through hole.

[0026] In this technical solution, building upon the aforementioned technical solution, a first limiting part and a second limiting part for limiting the elastic element are respectively provided inside the through hole and on the support part. Specifically, the first limiting part is located inside the through hole, and the second limiting part is located at the end of the support part away from the through hole.

[0027] One end of the elastic element is in contact with the first limiting part, and the other end of the elastic element is in contact with the second limiting part.

[0028] When the cam mechanism is rotated to the first angle by operation, the working surface on the cam presses against the support part in the direction of the first housing, causing the support part to move in the direction of the first housing and extend out of the through hole. At this time, the distance between the first and second limiting members shortens, compressing the elastic member located between them. After the operation on the cam is removed, the elastic member releases its elastic potential energy, moving the second limiting member away from the first limiting member, thereby driving the support part to move away from the first housing. This completes the automatic reset of the telescopic member, thereby improving the operability of the telescopic member and providing convenience for the user.

[0029] In any of the above technical solutions, multiple support parts are provided, and the telescopic component also includes a connecting part, with multiple support parts connected to the connecting part.

[0030] In this technical solution, building upon the aforementioned technical solution, the structure of the telescopic component is further defined. Specifically, there are multiple support parts. The telescopic component is also provided with connecting parts, which are located within the cavity. Multiple support parts are located on the side of the connecting parts facing the through hole and are connected to the connecting parts, while the side of the connecting parts facing away from the through hole abuts against the cam mechanism.

[0031] During the rotational motion of the cam mechanism, a force is applied to the connecting part, which is connected to multiple support parts, causing the multiple support parts to move in the same direction. At this time, the elastic elements on the multiple support parts are compressed. After the operation on the cam mechanism is removed, the multiple elastic elements release their elastic potential energy, which can drive the multiple support parts to return to their original position. Through the connection of the connecting part, it is ensured that the multiple support parts can move synchronously when moving towards or away from the first housing, thus ensuring the stability of the adjustment of the distance between the first housing and the second housing.

[0032] In any of the above technical solutions, multiple through holes are provided, and multiple support parts are provided in a one-to-one correspondence with multiple through holes.

[0033] In this technical solution, the number of through holes is limited. Specifically, the telescopic component is provided with multiple support parts, which are located in different areas of the second shell. Simultaneously, the second shell has multiple through holes, the same number as the support parts. Each support part corresponds to one through hole, meaning multiple support parts can move within their corresponding through holes to adjust the distance between different areas of the first and second shells. Compared to a solution using only one set of through holes and support parts, this approach offers several advantages. First, by using multiple sets of support parts and through holes, multi-point support can be achieved during synchronous adjustment, preventing the tilted first and second shells from accidentally contacting food, thus improving adjustment accuracy. Second, the distance between local areas of the first and second shells can be adjusted by controlling the extension and retraction of some of the support parts within their corresponding through holes. For example, when a user simultaneously heats pancakes and buns using a grill, they can individually adjust the support part corresponding to the bun's area to tilt the top shell, heating the bun in areas with larger distances and the pancake in areas with smaller distances, thereby achieving simultaneous heating of various food types while ensuring food quality. This achieves the technical effect of optimizing the structure of the telescopic components, expanding the application range of the grill, and providing convenient conditions for users.

[0034] In any of the above technical solutions, the cam mechanism includes: a rotating shaft, which is rotatably connected to the second housing; and a cam, which is sleeved on the rotating shaft, and the circumferential surface of the cam is used to push the telescopic component to move.

[0035] This technical solution provides a detailed description of the cam mechanism. Specifically, the cam mechanism includes a rotating shaft and a cam. The rotating shaft is mounted on a housing and can rotate around its own axis on a second housing. The cam is mounted on the rotating shaft and rotates synchronously with the shaft around its axis. The cam extends outward from its circumferential surface relative to the rotating shaft, and this circumferential surface abuts against the telescopic member; that is, the circumferential surface of the cam is the working surface in the aforementioned technical solution. During operation, the rotating shaft drives the cam to rotate. When the circumferential surface extending towards the rotating shaft rotates to a position between the rotating shaft and the telescopic member, the distance between the rotating shaft and the telescopic member is forced to increase, thereby pushing the telescopic member towards the first housing so that the support portion extends out of the through hole. The adjustment stroke between the first and second housings is related to the shape of the cam, which will not be described in detail here.

[0036] In one possible implementation, the cam can be a structure sleeved on a rotating shaft, and the cam and rotating shaft are detachably connected. By providing a detachable rotating shaft and cam, maintenance of the cam mechanism is facilitated. For example, when the cam malfunctions, the user can disassemble and repair it or replace it with a new one, thus efficiently completing mechanism maintenance. Furthermore, the detachable cam design allows users to adjust the spacing of the cam mechanism by changing the type of cam; for example, replacing it with a larger cam can meet the heating requirements of large-volume foods. This ultimately broadens the applicability of the grill and enhances its functionality and practicality.

[0037] In another possible implementation, the cam and shaft are integrated into a single structure. Manufacturing the cam and shaft using a one-piece molding process reduces the manufacturing complexity of the cam mechanism, eliminating the cumbersome steps of machining the mating assembly structure, thereby improving production efficiency and reducing production costs. Furthermore, the absence of structural cross-sections between the integrated cam and shaft helps improve the structural strength of the cam mechanism, reducing the probability of cam misalignment or even breakage.

[0038] In any of the above technical solutions, the cam mechanism further includes: a baffle, disposed on the rotating shaft, with the baffle and the cam arranged sequentially in the axial direction of the rotating shaft, and the baffle being able to limit the rotation shaft in the axial direction of the rotating shaft.

[0039] This technical solution defines the axial limiting structure of the cam mechanism. Specifically, a baffle is provided on the cam mechanism, positioned on the rotating shaft, and sequentially connected to the cam along the axial direction of the shaft. The baffle's coverage area on the plane perpendicular to the shaft axis is larger than the cam's coverage area on that plane. When the cam mechanism moves along the shaft axis, the baffle abuts against the telescopic component, specifically against the connecting part of the telescopic component, thus achieving axial limiting of the cam mechanism and preventing it from deviating from its intended position with the telescopic component. This optimizes the cam mechanism's structure, improves its transmission reliability and accuracy, and reduces its failure rate.

[0040] Specifically, the baffle can be a single baffle, which is adjacent to the cam along the axis of rotation. When the baffle is positioned outside the cam, it restricts the cam mechanism from moving into the second housing, preventing the user from accidentally pushing the cam mechanism into the second housing while operating it. Conversely, when the baffle is positioned inside the cam, it restricts the cam mechanism from moving out of the second housing, preventing the user from accidentally pulling the cam mechanism out of the second housing while operating it.

[0041] Alternatively, a baffle can be installed on each side of the cam mechanism, ensuring that the distance between the two baffles is greater than or equal to the distance between the connecting parts along the axis of rotation, so that the connecting parts can be positioned between the two baffles. This restricts the displacement of the cam mechanism along the axis of rotation by the inner and outer baffles, allowing the cam mechanism to be accurately positioned at a predetermined working position. The distance between the two baffles is not rigidly defined in this technical solution; it can be adjusted accordingly to accommodate other functional structures. For example, increasing the distance between the two baffles can provide a push-pull operation margin for the locking mechanism, which will not be elaborated further here.

[0042] In any of the above technical solutions, the grill also includes a limiting component disposed in the second housing, the limiting component being used to limit the radial movement of the rotating shaft.

[0043] In this technical solution, the radial limiting structure of the cam mechanism is defined. Specifically, a limiting component is provided on the second housing, which cooperates with the rotating shaft to limit the displacement of the shaft in its own radial direction. By setting a limiting component that can restrict the radial movement of the rotating shaft, the rotating shaft can be accurately positioned at the predetermined working position, avoiding misalignment of the rotating shaft caused by user operation, vibration, or other external factors. This ensures that the rotating cam mechanism can trigger the telescopic component to adjust the distance between the first and second housings. This achieves the technical effects of optimizing the positioning reliability and stability of the cam mechanism, improving the transmission accuracy of the cam mechanism and the telescopic component, reducing the probability of transmission jamming, and lowering the failure rate of the grill.

[0044] The limiting components can be structures such as bearings, shaft holes, and sleeves. This technical solution does not impose strict limitations on these components, as long as they meet the axial limiting requirements of the rotating shaft.

[0045] In any of the above technical solutions, the limiting component includes: a positioning plate with a positioning groove, a rotating shaft being disposed in the positioning groove, the positioning groove being used to position the rotating shaft in the radial direction; two positioning members, the positioning plate being located between the two positioning members; and a blocking member connected to the two positioning members, the blocking member being located at the end of the two positioning members away from the second housing.

[0046] This technical solution, building upon the aforementioned solution, defines the structure of the limiting component. Specifically, the limiting component includes a positioning plate, positioning members, and a blocking member. The positioning plate is mounted on the second housing and has a positioning groove. The rotating shaft is located within the positioning groove and can rotate within it. The positioning groove limits the rotation of the shaft radially. Two positioning members are located on either side of the positioning plate, effectively preventing the rotating shaft from dislodging. Furthermore, the blocking member connects to the ends of the two positioning members furthest from the second housing, forming a positioning hole through which the rotating shaft can pass. The shaft can rotate within the positioning hole, but when the shaft undergoes radial displacement due to external factors, the positioning members and the blocking member act as a barrier, thus achieving radial limiting of the shaft. This optimizes the limiting component structure, improves the stability and transmission accuracy of the cam mechanism, and reduces the failure rate of the grill.

[0047] The shielding component and the positioning component are detachably connected. During assembly, the shaft is first placed into the positioning slot, and then the shielding component is placed on the two positioning components to complete the shaft assembly. Compared to the technical solution of inserting the shaft into the limiting component, this structure has the advantages of low assembly difficulty and high operability, eliminating the need to reserve an insertion channel for the shaft, thereby reducing structural complexity. On the other hand, the detachable shielding component provides convenient conditions for the maintenance of the shaft. For example, when the shaft malfunctions, the user can remove the shielding component and directly remove the shaft to efficiently complete the shaft repair or replacement, thereby improving the user experience.

[0048] In any of the above technical solutions, the grill also includes: a locking component, disposed in the second housing and connected to the rotating shaft, which can lock the rotating shaft onto the second housing.

[0049] In this technical solution, the grill is also equipped with a locking component. The locking component is located on the second housing and connects the second housing to the rotating shaft. The locking component locks the rotating shaft onto the second housing to prevent rotation and movement of the rotating shaft relative to the second housing. By providing the locking component, the user can lock the transmission mechanism, composed of the cam mechanism and the telescopic component, in a certain state, thereby maintaining the distance between the first and second housings at a predetermined distance to ensure that the top housing does not press against the food between the first and second housings.

[0050] The design incorporates a positioning protrusion on the circumferential surface of the rotating shaft and a locking groove on the locking element. Pushing the positioning protrusion into the locking groove locks the rotating shaft onto the second housing; conversely, removing the positioning protrusion from the locking groove releases the lock. The locking element can also have other structural forms; this technical solution does not impose strict limitations on these, as long as the locking requirements are met.

[0051] In any of the above technical solutions, the cam mechanism further includes: a knob, connected to the rotating shaft, located on the outside of the second housing.

[0052] In this technical solution, a knob is also provided on the cam mechanism. The knob is located outside the second housing and connected to the end of the rotating shaft that extends out of the second housing. The knob can rotate the rotating shaft and the cam to drive the cam mechanism. By providing a knob, convenient conditions are provided for the user to operate the cam mechanism, making it easy for the user to adjust the distance between the first and second housings.

[0053] Specifically, an anti-slip layer is provided on the peripheral surface of the knob. This anti-slip layer can be an irregular texture or a ring made of anti-slip material. This technical solution does not impose strict limitations on this; as long as it satisfies the requirement of anti-slip for touch control, it is acceptable.

[0054] In one feasible solution, the grill also includes a positioning ring embedded in the second housing. The positioning ring has mounting holes into which the knob is inserted. The positioning ring, in conjunction with the knob, assists in positioning the cam mechanism, thereby improving the transmission accuracy of the cam mechanism. Furthermore, the positioning ring has a scale marking around the knob, and the knob has a pointer. As the knob is rotated, the pointer points to a scale mark corresponding to the distance between the first and second housings. This allows the user to visually determine the current adjustment range, eliminating the need for repeated observation of the gap and facilitating precise control of the distance between the upper and lower housings. This ultimately improves the operability of the grill and enhances the user experience.

[0055] In any of the above technical solutions, the number of support components is at least two; at least two support components are evenly distributed on the second housing, and / or at least two support components are symmetrically distributed on the second housing.

[0056] This technical solution limits the number of support components. Specifically, the grill has at least two support components, distributed across different areas of the second housing. Compared to a single support component, using at least two supports increases the adjustability of the distance between the first and second housings. This allows the user to individually adjust the spacing of the target adjustment area using the support component corresponding to that area, enabling the top housing to tilt relative to the bottom housing. This allows the grill to simultaneously heat multiple foods of different sizes between the first and second housings. Ultimately, this improves the operability of the grill and provides greater convenience for the user.

[0057] At least two support components can be evenly distributed on the second housing. Specifically, on the second housing, at least two support components are evenly distributed on the same circle with the vertical centerline running through the second housing as the axis, forming a ring-shaped support component array on the second housing. This allows multiple support components to effectively support the top housing at multiple angles, preventing the top from tilting due to insufficient support. Simultaneously, the even distribution of multiple support components distributes the weight of the top housing evenly across multiple support components, reducing the risk of damage to any single support component due to excessive stress. At least two support components can also be symmetrically distributed on the second housing. This symmetrical distribution means that multiple support components are symmetrically distributed on both sides of the central axis of the second housing. For example, when two support components are provided, they are symmetrically arranged at the left and right ends of the second housing. When three support components are provided, two support components are symmetrically arranged on both sides of the central axis, with the remaining support component symmetrically separated by the central axis. The symmetrical distribution of multiple support components not only improves the support effectiveness of the top housing but also provides convenient conditions for users to adjust the tilt angle of the top housing. This achieves the technical effect of optimizing the distribution of support components and improving the practicality and reliability of the grill.

[0058] In any of the above technical solutions, the grill further includes: a connecting component, one end of which is connected to the first housing and the other end of which is connected to the second housing; wherein the second housing is rotatable relative to the first housing via the connecting component, and the second housing is axially movable relative to the first housing via the connecting component.

[0059] In this technical solution, the grill also includes a connecting assembly. One end of the connecting assembly is hinged to the first housing, and the other end is hinged to the second housing, thus connecting the upper and lower distributed first and second housings, allowing the first and second housings to rotate relative to each other about the hinge axis on the connecting assembly. Furthermore, the distance between the two hinge axes on the connecting assembly is adjustable. When the user raises the top housing by operating the support assembly, the connecting assembly extends in the height direction, thus coordinating with the adjustment of the distance between the first and second housings. In actual operation, the user can first adjust the distance between the top and bottom housings by manipulating the support assembly, then open the top housing, place the food on the bottom housing, and finally close the top housing to perform the heating operation.

[0060] In any of the above technical solutions, the grill further includes: a heating element disposed in the first housing and / or the second housing; wherein the heating element is located between the first housing and the second housing.

[0061] In this technical solution, the grill is also equipped with a heating element. The heating element can be disposed on the first housing and / or the second housing, specifically on the surface of the first housing facing the second housing, and on the surface of the second housing facing the first housing, so that food placed between the first housing and the second housing can be heated by the heating element.

[0062] In one possible implementation, a first housing is disposed on top of a second housing, and both the first and second housings are equipped with heating elements. During heating, the bottom of the food comes into contact with the heating element on the second housing, which transfers heat to the food through contact heat transfer. Meanwhile, the heating element on the first housing is spaced apart from the top of the food, and heat is transferred to the food via air, thus avoiding damage to the food due to pressure while meeting the requirements for efficient heating.

[0063] Specifically, the heating element can be an electric heating element. This technical solution does not elaborate on the specific structural form of the heating element, as long as it meets the food heating requirements.

[0064] It is worth noting that the structure in the aforementioned technical solution can be applied to electric griddles, electric baking pans, and grills, so that these three products can meet the heating needs of foods of different sizes by adjusting the gap between the upper and lower shells, and ensure that the food is not damaged during the heating process.

Detailed Implementation

[0074] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0075] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0076] The following reference Figures 1 to 5 A grilling machine according to some embodiments of the present invention is described.

[0077] Example 1

[0078] like Figure 1 , Figure 2 and Figure 5 As shown, a first aspect embodiment of the present invention provides a grill 100, which includes: a first housing 110; a second housing 120 movably connected to the first housing 110; and a support assembly 130 disposed on the second housing 120, the support assembly 130 including: a telescopic member 132 connected to the second housing 120; and a cam mechanism 134 that, when in motion, can drive the telescopic member 132 to move, thereby adjusting the distance between the first housing 110 and the second housing 120.

[0079] This application defines a grill 100 for heating food. Specifically, the grill 100 includes a first housing 110 and a second housing 120, which are two main structures on the grill 100. The first housing 110 and the second housing 120 are arranged opposite to each other in the height direction of the grill 100. The lower housing 110 is used to support and heat food, while the upper housing is used to position and heat food. This embodiment does not impose strict limitations on the specific functions of these two housings; satisfying the structural positional relationship and basic heating requirements is sufficient.

[0080] In related technologies, when cooking appliances with separate top and bottom shells heat food, the weight of the top shell presses the food down onto the bottom shell. However, when heating delicate foods that need to maintain their original shape, the pressure of the top shell can have a counterproductive effect, causing the food to be squeezed, deformed, or even broken. For example, when heating egg tarts or buns with a pressure-type cooking appliance, the pressing top shell can squeeze out the filling. Similarly, when heating crispy foods like pancakes or cookies with a pressure-type cooking appliance, the pressing top shell can crush the food. Therefore, it is clear that these technologies suffer from the problem of food being easily crushed.

[0081] In this regard, the grill 100 defined in this application is further provided with a support assembly 130. The support assembly 130 is disposed on the second housing 120 and contacts the first housing 110. The support assembly 130 can adjust the distance between the first housing 110 and the second housing 120 through structural support, so as to realize the adjustment of the spacing between the upper and lower housing structures of the grill 100. Specifically, the support assembly 130 includes a telescopic member 132 and a cam mechanism 134. The telescopic member 132 is disposed on the second housing 120 and can move relative to the second housing 120 to extend outside the second housing 120 or retract into the second housing 120. The cam mechanism 134 is disposed on the second housing 120 and includes an action surface whose position changes relative to the second housing 120 during rotation. During movement, the action surface can abut against the telescopic member 132.

[0082] During operation, adjusting the position of the working surface of the cam mechanism 134 can push the telescopic member 132 to move relative to the second housing 120. If the second housing 120 is located on top of the first housing 110, the extended telescopic member 132 can lift the second housing 120 to increase the distance between the second housing 120 and the first housing 110. Correspondingly, if the second housing 120 is located at the bottom of the first housing 110, the extended telescopic member 132 can lift the first housing 110, thus adjusting the distance between the first housing 110 and the second housing 120.

[0083] This allows users to adjust the distance between the first shell 110 and the second shell 120 to a range greater than or equal to the height of the food when heating foods that require shaping or have a crisp texture, by manipulating the support component 130. This prevents the upper shell from pressing down on the food. For example, when heating buns or pancakes using the grill 100 as defined in this application, the support component 130 can be manipulated to create a gap between the top shell and the bun or pancake, preventing the top shell from pressing out the filling of the bun or crushing the pancake. This solves the technical problems of food damage, limited types of heated foods, and poor user experience in the aforementioned related technologies. It optimizes the structure of the grill 100, improves its operability, expands its functional range, ensures the quality of the heated food, and enhances the user experience.

[0084] Example 2

[0085] like Figure 2 , Figure 3 and Figure 4 As shown, in a second aspect embodiment of the present invention, the second housing 120 includes a through hole, and the telescopic member 132 includes a support portion 1322, which is disposed corresponding to the through hole; wherein, when the cam mechanism 134 rotates to a first angle, at least a portion of the support portion 1322 passes through the through hole and contacts the first housing 110, and the first housing 110 and the second housing 120 are spaced apart by a first distance; when the cam mechanism 134 rotates to a second angle, the first housing 110 and the second housing 120 are spaced apart by a second distance.

[0086] In this embodiment, the second housing 120 has a cavity and a through hole connecting the cavity and the external space. When the first housing 110 and the second housing 120 are engaged, the through hole faces the direction of the first housing 110. Based on this, the structure of the telescopic member 132 will be described in detail. Specifically, the telescopic member 132 includes a support portion 1322, the shape of which is adapted to the outer contour of the support portion 1322, allowing the support portion 1322 to move along the axis of the through hole. During the movement of the cam mechanism 134, the support portion 1322 abuts against the working surface of the cam mechanism 134.

[0087] In the cam mechanism 134, the radial distance between different areas on the working surface and the rotation axis varies. During the rotation of the cam mechanism 134, the working surface rotates around the rotation axis of the cam mechanism 134. Therefore, the distance between the working surface abutting the support part 1322 and the rotation axis changes during the rotation process. When this distance increases, the support part 1322 is pushed out of the through hole by the cam mechanism 134. Correspondingly, when this distance decreases, the support part 1322 can be reset by gravity or elasticity to retract into the through hole. This achieves the technical effect of optimizing the structure of the telescopic member 132, improving the operability of the grill 100, and improving the quality of the heated food.

[0088] Specifically, the cam mechanism 134 has two critical angles: a first angle and a second angle.

[0089] When the cam mechanism 134 rotates to the first angle, the radial distance between the working surface abutting the support 1322 and the rotation axis is the maximum value of the entire rotation stroke, corresponding to the longest extension distance of the support 1322 relative to the through hole. At this time, the support 1322 can lift the first housing 110 or the second housing 120 located at the top, so that the first housing 110 and the second housing 120 are spaced apart by a first distance to avoid the food being squeezed by the housing.

[0090] When the cam mechanism 134 rotates to the second angle, the radial distance between the working surface abutting the support 1322 and the rotation axis is the minimum value of the entire rotation stroke. At this time, the support 1322 retracts into the cavity, or the lower section of the support 1322 is flush with the bottom surface of the second housing 120. At this time, the first housing 110 and the second housing 120 are separated by a second distance.

[0091] It is worth noting that the first distance is greater than the second distance, and the second distance can be greater than or equal to 0.

[0092] Based on the user's actual cooking needs using the grill 100, the distance between the first housing 110 and the second housing 120 is controlled by the angle of the rotating cam mechanism 134. For example, when the user needs to cook foods that are not easily compressed, such as buns or pancakes, the distance between the first housing 110 and the second housing 120 can be controlled by a first distance to prevent the first housing 110 and the second housing 120 from compressing the food. When the user needs to cook thinner foods that can be compressed, such as meat, the distance between the first housing 110 and the second housing 120 can be controlled by a second distance to reduce the contact area between the food and the air.

[0093] In any of the above embodiments, the telescopic member 132 further includes: an elastic member 1326 sleeved on the support portion 1322, wherein when the cam mechanism 134 rotates to the first angle, the elastic member 1326 undergoes elastic deformation, and when the cam mechanism 134 rotates to the second angle, the elastic member 1326 drives the support portion 1322 to reset.

[0094] In this embodiment, an elastic element 1326 is further provided in the telescopic member 132, and the elastic element 1326 is sleeved on the support part 1322. When the cam mechanism 134 rotates to the first angle, the deformation of the elastic element 1326 is minimal. At this time, the elastic element 1326 can overcome the weight of the telescopic member 132, allowing the telescopic member 132 to stop in the retracted position. When the cam mechanism 134 is rotated out of the first angle by operation, the action surface on the cam 1344 presses against the support part 1322 in the direction of the first housing 110, causing the support part 1322 to move in the direction of the first housing 110. The support part 1322 extends out of the through hole, and the elastic element 1326 is compressed by the support part 1322. After the operation on the cam 1344 is removed, the elastic element 1326 releases its elastic potential energy, pushing the support part 1322 back to move away from the first housing 110. This allows for the automatic reset of the telescopic component 132, thereby improving its operability and providing convenience for users.

[0095] Specifically, the elastic element 1326 can be a spring. The spring is sleeved around the support portion 1322, with one end of the spring abutting against the second housing 120 near the through hole and the other end abutting against the support portion 1322. After the cam mechanism 134 rotates to the first angle, the spring is compressed. Conversely, after the operation is removed, the compressed spring will spring the support portion 1322 back to the initial position.

[0096] The elastic element 1326 can also be an elastic retaining ring filled between the connecting part 1324 and the second housing 120. After the cam mechanism 134 rotates to the first angle, the elastic retaining ring is compressed and deformed. Conversely, after the operation is removed, the compressed and deformed elastic retaining ring will spring back the support part 1322 to the initial position.

[0097] In addition, the elastic element 1326 can also be a component composed of various elastic structures. This embodiment does not impose a rigid limitation on this, as long as it meets the automatic reset requirement.

[0098] In any of the above technical solutions, a first limiting part for axially limiting the elastic member 1326 is provided in the through hole; a second limiting part for axially limiting the elastic member 1326 is provided in the support part 1322 in the direction away from the through hole.

[0099] In this technical solution, following the aforementioned technical solution, a first limiting part and a second limiting part for limiting the elastic member 1326 are respectively provided inside the through hole and on the support part 1322. The first limiting part is located inside the through hole, and the second limiting part is located at the end of the support part 1322 away from the through hole.

[0100] One end of the elastic member 1326 is in contact with the first limiting part, and the other end of the elastic member 1326 is in contact with the second limiting part.

[0101] When the cam mechanism is rotated to the first angle by operation, the working surface on the cam presses against the support portion 1322 in the direction of the first housing 110, causing the support portion 1322 to move in the direction of the first housing 110. The support portion 1322 extends out of the through hole. At this time, the distance between the first and second limiting members shortens, compressing the elastic member 1326 located between them. After the operation on the cam is removed, the elastic member 1326 releases its elastic potential energy, moving the second limiting member away from the first limiting member, thereby driving the support portion 1322 to move away from the first housing 110. This completes the automatic reset of the telescopic member 132, thereby improving the operability of the telescopic member 132 and providing convenience for the user.

[0102] In any of the above technical solutions, the support part 1322 is provided in multiple ways, and the telescopic member 132 further includes a connecting part 1324, with the multiple support parts 1322 connected to the connecting part 1324.

[0103] In this technical solution, building upon the aforementioned technical solution, the structure of the telescopic member 132 is further defined. Specifically, there are multiple support portions 1322. The telescopic member 132 is also provided with a connecting portion 1324, which is located within the cavity. Multiple support portions 1322 are disposed on the side of the connecting portion 1324 facing the through hole and are connected to the connecting portion 1324. The side of the connecting portion 1324 facing away from the through hole abuts against the cam mechanism 134.

[0104] During the rotational movement of the cam mechanism 134, a force is applied to the connecting portion 1324, which is connected to multiple support portions 1322, causing the multiple support portions 1322 to move in the same direction. At this time, the elastic elements 1326 on the multiple support portions 1322 are compressed. After the operation on the cam mechanism 134 is removed, the multiple elastic elements 1326 release their elastic potential energy, which can drive the multiple support portions 1322 to return to their original position. Through the connection of the connecting portion 1324, it is ensured that the multiple support portions 1322 can move synchronously when moving towards or away from the first housing 110, thus ensuring the stability of the adjustment of the distance between the first housing 110 and the second housing 120.

[0105] In any of the above embodiments, multiple through holes are provided, and multiple support portions 1322 are provided in a one-to-one correspondence with multiple through holes.

[0106] In this embodiment, the number of through holes is limited. Specifically, the telescopic member 132 is provided with multiple support portions 1322, which are disposed in different areas of the second housing 120. Simultaneously, the second housing 120 is provided with multiple through holes, the same number as the number of support portions 1322. Each support portion 1322 corresponds to one through hole, meaning that multiple support portions 1322 can move within their corresponding through holes to adjust the distance between different areas of the first housing 110 and the second housing 120. Compared to an embodiment with only one set of through holes and support portions 1322, on the one hand, by providing multiple sets of support portions 1322 and through holes, multi-point support can be achieved during synchronous adjustment, preventing the tilted first housing 110 and second housing 120 from accidentally contacting food, thereby improving adjustment accuracy. On the other hand, the distance between local areas of the first housing 110 and the second housing 120 can be adjusted by controlling the extension and retraction of some of the multiple support portions 1322 within their corresponding through holes. For example, when a user simultaneously heats pancakes and buns using the grill 100, they can adjust the extension of the support 1322 corresponding to the bun's area to tilt the top shell, heating the bun in areas with larger gaps and heating the pancake in areas with smaller gaps. This allows for simultaneous heating of various food shapes while maintaining food quality. Furthermore, this optimizes the structure of the telescopic component 132, broadens the applicability of the grill 100, and provides users with greater convenience.

[0107] Example 3

[0108] like Figure 2 , Figure 3 and Figure 4 As shown, in a third aspect embodiment of the present invention, the cam mechanism 134 includes: a rotating shaft 1342 rotatably connected to the second housing 120; and a cam 1344 sleeved on the rotating shaft 1342, the peripheral side of the cam 1344 being used to push the telescopic member 132 to move.

[0109] In this embodiment, the cam mechanism 134 is described in detail. Specifically, the cam mechanism 134 includes a rotating shaft 1342 and a cam 1344. The rotating shaft 1342 is mounted on the housing and can rotate on its own axis on the second housing 120. The cam 1344 is mounted on the rotating shaft 1342 and rotates synchronously with the rotating shaft 1342 about its axis. The cam 1344 extends outward relative to the circumferential surface of the rotating shaft 1342, and the circumferential surface of the cam 1344 abuts against the telescopic member 132; that is, the circumferential surface of the cam 1344 is the working surface in the aforementioned embodiment. During operation, the rotating shaft 1342 drives the cam 1344 to rotate. When the circumferential side extending towards the circumference of the rotating shaft 1342 rotates to a position between the rotating shaft 1342 and the telescopic member 132, the distance between the rotating shaft 1342 and the telescopic member 132 is forced to increase, thereby pushing the telescopic member 132 towards the first housing 110, so that the support part 1322 extends out of the through hole. The adjustment stroke between the first housing 110 and the second housing 120 is related to the shape of the cam 1344, which will not be explained in detail.

[0110] In one possible implementation, the cam 1344 can be a structure sleeved on the rotating shaft 1342, and the cam 1344 and the rotating shaft 1342 are detachably connected. By providing a detachable rotating shaft 1342 and cam 1344, maintenance of the cam mechanism 134 can be facilitated. For example, when the cam 1344 malfunctions, the user can disassemble and repair it or replace it with a new one, thus efficiently completing mechanism maintenance. Furthermore, the detachable cam 1344 allows the user to adjust the spacing of the cam mechanism 134 by changing the type of cam 1344; for example, replacing it with a larger cam 1344 can meet the heating requirements of large-volume foods. This, in turn, broadens the applicability of the grill 100 and enhances its functionality and practicality.

[0111] In another possible real-time solution, the cam 1344 and the shaft 1342 are integrated into a single structure. Manufacturing the cam 1344 and shaft 1342 using a one-piece molding process reduces the manufacturing complexity of the cam mechanism 134, eliminating the complex steps of machining the mating assembly structure between the two, thereby improving the production efficiency and reducing the production cost of the cam mechanism 134. Furthermore, the absence of structural cross-sections between the integrated cam 1344 and shaft 1342 helps improve the structural strength of the cam mechanism 134, reducing the probability of misalignment or even breakage of the cam 1344.

[0112] In any of the above embodiments, the cam mechanism 134 further includes a baffle 1346 disposed on the rotating shaft 1342. The baffle 1346 and the cam 1344 are arranged sequentially in the axial direction of the rotating shaft 1342. The baffle 1346 can limit the rotating shaft 1342 in the axial direction of the rotating shaft 1342.

[0113] In this embodiment, the axial limiting structure of the cam mechanism 134 is defined. Specifically, a baffle 1346 is provided on the cam mechanism 134, which is disposed on the rotating shaft 1342, and the baffle 1346 is sequentially connected to the cam 1344 in the axial direction of the rotating shaft 1342. The coverage area of ​​the baffle 1346 on the plane perpendicular to the axis of the rotating shaft 1342 is larger than the coverage area of ​​the cam 1344 on the same plane. When the cam mechanism 134 moves along the axial direction of the rotating shaft 1342, the baffle 1346 can abut against the telescopic member 132, specifically against the connecting portion 1324 on the telescopic member 132, thereby achieving axial limiting of the cam mechanism 134 and preventing the cam mechanism 134 from deviating from its working position in conjunction with the telescopic member 132. This optimizes the structure of the cam mechanism 134, improves the transmission reliability and accuracy of the cam mechanism 134, and reduces the failure rate of the cam mechanism 134.

[0114] Specifically, the baffle 1346 can be a single baffle. A single baffle 1346 is adjacent to the cam 1344 along the axis of the rotating shaft 1342. When the baffle 1346 is positioned outside the cam 1344, it restricts the cam mechanism 134 from moving into the second housing 120, preventing the user from accidentally pushing the cam mechanism 134 into the second housing 120 while operating it. Conversely, when the baffle 1346 is positioned inside the cam 1344, it restricts the cam mechanism 134 from moving outside the second housing 120, preventing the user from accidentally pulling the cam mechanism 134 out of the second housing 120 while operating it.

[0115] In this embodiment, a baffle 1346 can be provided on each side of the cam mechanism 134, ensuring that the distance between the two baffles 1346 is greater than or equal to the distance of the connecting part 1324 along the axis of the rotating shaft 1342, so that the connecting part 1324 can be positioned between the two baffles 1346. Thus, the displacement of the cam mechanism 134 along the axis of the rotating shaft 1342 is restricted by the inner and outer baffles 1346, allowing the cam mechanism 134 to be accurately positioned at a predetermined working position. The distance between the two baffles 1346 is not rigidly defined in this embodiment; it can be adjusted accordingly to accommodate other functional structures. For example, increasing the distance between the two baffles 1346 can provide a push-pull operation margin for the locking mechanism, which will not be elaborated further here.

[0116] like Figure 2As shown, in any of the above embodiments, the grill 100 further includes a limiting component disposed in the second housing 120, the limiting component being used to limit the radial movement of the rotating shaft 1342.

[0117] In this embodiment, a radial limiting structure is provided for the cam mechanism 134. Specifically, a limiting component is provided on the second housing 120, which cooperates with the rotating shaft 1342 to limit the displacement of the shaft in its own radial direction. By providing a limiting component that can limit the radial movement of the rotating shaft 1342, the rotating shaft 1342 can be accurately positioned in a predetermined working position, avoiding misalignment of the rotating shaft 1342 caused by user operation, vibration, or other external factors. This ensures that the rotating cam mechanism 134 can trigger the telescopic member 132 to adjust the distance between the first housing 110 and the second housing 120. This achieves the technical effects of optimizing the positioning reliability and stability of the cam mechanism 134, improving the transmission accuracy of the cam mechanism 134 and the telescopic member 132, reducing the probability of transmission jamming, and reducing the failure rate of the grill 100.

[0118] The limiting component can be a bearing, shaft hole, sleeve, or other structure. This embodiment does not impose strict limitations on this, as long as it meets the axial limiting requirements of the rotating shaft 1342.

[0119] like Figure 2 and Figure 3 As shown, in any of the above embodiments, the limiting component 140 includes: a positioning plate 142, on which a positioning groove 144 is provided, and a rotating shaft 1342 is disposed in the positioning groove 144, the positioning groove 144 being used to position the rotating shaft 1342 in the radial direction; two positioning members 146, with the positioning plate 142 located between the two positioning members 146; and a blocking member connected to the two positioning members 146, the blocking member being located at the end of the two positioning members away from the second housing 120.

[0120] In this embodiment, following the previous embodiment, the structure of the limiting component 140 is defined. Specifically, it includes a positioning plate 142, positioning members 146, and a blocking member. The positioning plate 142 is disposed on the second housing 120, and a positioning groove 144 is provided on the positioning plate 142. The rotating shaft 1342 is located in the positioning groove 144, and the rotating shaft 1342 can rotate within the positioning groove 144. The positioning groove 144 can limit the rotating shaft 1342 radially. Two positioning members 146 are located on both sides of the positioning plate 142, and the two positioning members 146 cooperate with the positioning plate 142 to effectively prevent the rotating shaft from coming out. Based on this, the blocking component is connected to the ends of the two positioning components 146 away from the second housing 120 to cooperate with the positioning groove 144 to form a positioning hole through which the rotating shaft 1342 can pass. The rotating shaft 1342 can rotate in the positioning hole, but when the rotating shaft 1342 undergoes radial displacement due to external factors, the positioning component 146 and the blocking component can act as a blocking force, thereby completing the radial limit of the rotating shaft 1342. This achieves the technical effect of optimizing the structure of the limiting component 140, improving the working stability and transmission accuracy of the cam mechanism 134, and reducing the failure rate of the grill 100.

[0121] In this design, the shielding component and the positioning component are detachably connected. During assembly, the rotating shaft 1342 is first placed into the positioning groove 144, and then the shielding component is placed on the two positioning components 146 to complete the assembly of the rotating shaft 1342. Compared with the embodiment where the rotating shaft 1342 is inserted into the limiting component 140, this structure has the advantages of low assembly difficulty and high operability, eliminating the need to reserve an insertion channel for the rotating shaft 1342, thereby reducing structural complexity.

[0122] On the other hand, the removable cover can provide convenience during the maintenance of the hinge 1342. For example, if the hinge 1342 malfunctions, the user can remove the cover and directly take out the hinge 1342 to efficiently complete the repair or replacement of the hinge 1342, thereby improving the user experience.

[0123] In any of the above embodiments, the grill 100 further includes a locking member 150, disposed in the second housing 120, connected to the rotating shaft 1342, which can lock the rotating shaft 1342 onto the second housing 120.

[0124] In this embodiment, the grill 100 is also equipped with a locking member 150. The locking member 150 is disposed on the second housing 120 and connects the second housing 120 and the rotating shaft 1342. The locking member 150 can lock the rotating shaft 1342 on the second housing 120 to prevent the rotating shaft 1342 from rotating relative to the second housing 120 and to prevent the rotating shaft 1342 from moving relative to the second housing 120. By providing the locking member 150, the user can lock the transmission mechanism composed of the cam mechanism 134 and the telescopic member 132 in a certain state to lock the distance between the first housing 110 and the second housing 120 at a predetermined distance, so as to ensure that the top housing does not touch the food between the first housing 110 and the second housing 120.

[0125] In this design, a positioning protrusion can be provided on the circumferential side of the rotating shaft 1342, and a locking groove can be provided on the locking member 150. Pushing the positioning protrusion into the locking groove will lock the rotating shaft 1342 onto the second housing 120; conversely, pushing the positioning protrusion out of the locking groove will release the lock. The locking member 150 can also have other structural forms, which are not strictly limited in this embodiment, as long as they meet the locking requirements.

[0126] In any of the above embodiments, the cam mechanism 134 further includes a knob 1348, which is connected to the rotating shaft 1342 and located on the outside of the second housing 120.

[0127] In this embodiment, a knob 1348 is also provided on the cam mechanism 134. The knob 1348 is located outside the second housing 120 and connected to the end of the rotating shaft 1342 that extends out of the second housing 120. The knob 1348 can rotate both the rotating shaft 1342 and the cam 1344 to drive the cam mechanism 134. By providing the knob 1348, convenient conditions are provided for the user to operate the cam mechanism 134, making it easy for the user to adjust the distance between the first housing 110 and the second housing 120.

[0128] Specifically, an anti-slip layer is provided on the peripheral side of the knob 1348. This anti-slip layer can be an irregular texture or a loop made of anti-slip material. This embodiment does not impose strict limitations on this, as long as it satisfies the requirement of touch anti-slip.

[0129] In one feasible solution, the grill 100 is further equipped with a positioning ring, which is embedded in the second housing 120 and has mounting holes. A knob 1348 is inserted into these mounting holes. The positioning ring, in conjunction with the knob 1348, assists in positioning the cam mechanism 134, thereby improving the transmission accuracy of the cam mechanism 134. Furthermore, the positioning ring has a scale value surrounding the knob 1348, and the knob 1348 has a pointer. During rotation of the knob 1348, the pointer points to a scale value corresponding to the distance between the first housing 110 and the second housing 120. This allows the user to visually determine the current adjustment range, eliminating the need for repeated observation of the gap and facilitating precise control of the distance between the upper and lower housings. This ultimately improves the operability of the grill 100 and enhances the user experience.

[0130] Example 4

[0131] like Figure 2 , Figure 3 and Figure 4 As shown, in the fourth aspect embodiment of the present invention, in any of the above embodiments, the number of support components 130 is at least two; at least two support components 130 are evenly distributed on the second housing 120, and / or at least two support components 130 are symmetrically distributed on the second housing 120. In this embodiment, the number of support components 130 is limited. Specifically, the grill 100 is provided with at least two support components 130, and the at least two support components 130 are distributed in different areas of the second housing 120. Compared with providing a single support component 130, by providing at least two support components 130, the degree of freedom of adjustment of the distance between the first housing 110 and the second housing 120 can be improved, allowing the user to adjust the interval of the target adjustment area individually through the support component 130 corresponding to the target adjustment area, so that the top housing can be tilted relative to the bottom housing, and the grill 100 can simultaneously heat multiple foods of different sizes between the first housing 110 and the second housing 120. This achieves the technical effect of improving the operability of the grill 100 and providing convenient conditions for the user.

[0132] Following the aforementioned embodiments, the distribution of the multiple support components 130 on the second housing 120 is defined. At least two support components 130 can be evenly distributed on the second housing 120. Specifically, on the second housing 120, at least two support components 130 are evenly distributed on the same circle with the vertical centerline penetrating the second housing 120 as the axis, forming a ring-shaped array of support components 130 on the second housing 120. This allows the multiple support components 130 to effectively support the top housing from multiple angles, preventing the top from tilting due to insufficient support. Simultaneously, the even distribution of the multiple support components 130 distributes the weight of the top housing evenly across the multiple support components 130, reducing the risk of damage to any single support component due to excessive force. At least two support components 130 can also be symmetrically distributed on the second housing 120. This symmetrical distribution means that the multiple support components 130 are symmetrically distributed on both sides of the central axis of the second housing 120. For example, when two support components 130 are provided, the two support components 130 are symmetrically arranged at the left and right ends of the second housing 120. When three support components 130 are provided, two support components 130 are symmetrically arranged on both sides of the central axis, and the remaining support component 130 is symmetrically separated by the central axis. This symmetrical distribution of multiple support components 130 not only improves the support effectiveness of the top shell but also provides convenient conditions for users to adjust the tilt angle of the top shell. This optimizes the distribution of the support components 130, thereby enhancing the practicality and reliability of the grill 100.

[0133] In any of the above embodiments, the grill 100 further includes: a connecting component, one end of which is connected to the first housing 110 and the other end of which is connected to the second housing 120; wherein the second housing 120 is rotatable relative to the first housing 110 via the connecting component, and the second housing 120 is axially movable relative to the first housing 110 via the connecting component.

[0134] In this embodiment, the grill 100 also includes a connecting assembly. One end of the connecting assembly is hinged to the first housing 110, and the other end is hinged to the second housing 120, thereby connecting the vertically distributed first housing 110 and second housing 120, allowing the first housing 110 and second housing 120 to rotate relative to each other about the hinge axis on the connecting assembly. Furthermore, the distance between the two hinge axes on the connecting assembly is adjustable. When the user raises the top housing by operating the support assembly 130, the connecting assembly extends in the height direction, thus coordinating with the adjustment of the distance between the first housing 110 and the second housing 120. In actual operation, the user can first adjust the distance between the top and bottom housings by manipulating the support assembly 130, then open the top housing, place the food on the bottom housing, and finally close the top housing to perform the heating operation.

[0135] In any of the above embodiments, the grill 100 further includes a heating element disposed in the first housing 110 and / or the second housing 120; wherein the heating element is located between the first housing 110 and the second housing 120.

[0136] In this embodiment, the grill 100 is also provided with a heating element. The heating element can be disposed on the first housing 110 and / or the second housing 120. Specifically, the heating element can be disposed on the surface of the first housing 110 facing the second housing 120, and on the surface of the second housing 120 facing the first housing 110, so that food placed between the first housing 110 and the second housing 120 can be heated by the heating element.

[0137] In one possible implementation, a first housing 110 is disposed on top of a second housing 120, and both the first housing 110 and the second housing 120 are equipped with heating elements. During heating, the bottom of the food comes into contact with the heating element on the second housing 120, and the heating element transfers heat to the food through contact heat transfer. Meanwhile, the heating element on the first housing 110 is spaced apart from the top of the food, and heat is transferred to the food via air, thus avoiding damage to the food due to pressure while meeting the requirements for efficient heating.

[0138] Specifically, the heating element can be an electric heating element. This embodiment will not elaborate on the specific structural form of the heating element, as long as it meets the food heating requirements.
