Description

Technical Field

[0001] This utility model relates to the field of grilling machine technology, and more specifically, to a grilling machine. Background Technology

[0002] For grills with a flip-top lid, the lid and base are rotatably connected via pivots and hinges. However, when the lid is in the hovering position during the opening process, the hinge's poor positioning stability makes it prone to tilting, thus preventing it from stably keeping the lid in the hovering position. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, the present invention proposes a grill, comprising: a top cover assembly; a hinge portion rotatably connected to the top cover assembly; and a base assembly, wherein the top cover assembly rotates relative to the base assembly between a closed position, a suspended position, and a fully extended position via the hinge portion. The base assembly is provided with a receiving groove, at least a portion of the hinge portion is located within the receiving groove, and the hinge portion is capable of moving and rotating within the receiving groove. In the closed position and the suspended position, at least a portion of the hinge portion rests on the bottom of the receiving groove. A stop portion is provided within the receiving groove. The distance between the stop and the bottom of the receiving groove is less than the distance between the stop and the top of the receiving groove, and the stop is higher than or flush with the bottom of the groove. In the direction from the bottom of the receiving groove to the opening of the receiving groove, a part of the stop bends away from the hinge. The upper cover assembly is in the suspended position, and when the hinge is in contact with the stop, the hinge restricts the upper cover assembly from rotating from the suspended position to the maximum unfolded position. When the hinge is separated from the stop, the hinge can rotate with the upper cover assembly between the suspended position and the maximum unfolded position.

[0005] Both the top cover assembly and the base assembly are connected to a hinge. The top cover assembly rotates relative to the base assembly via the hinge, thus enabling the opening and closing of the cover. The top cover assembly can rotate within a range of 0° and 180°. When in the closed position, the angle of the top cover assembly relative to the horizontal plane may be equal to 0° or slightly greater than 0°. When in the fully extended position, the angle of the top cover assembly relative to the horizontal plane may be equal to 180° or slightly less than 180°. The hover position lies between the closed and fully extended positions; for example, in the hover position, the angle of the top cover assembly relative to the horizontal plane is 90° or close to 90°.

[0006] A receiving groove is machined into the base assembly, and at least a portion of the hinge is received in the receiving groove. The receiving groove accommodates the hinge and prevents the hinge from being excessively exposed on the surface of the grill, thereby improving the overall effect of the product.

[0007] The hinge can move within the receiving groove, allowing the top cover assembly to have a certain floating space relative to the base assembly. When the food inside the cooking cavity expands due to heat, the top cover assembly can float upwards, thereby increasing the space of the cooking cavity.

[0008] Before the top cover assembly is flipped to the hovering position, the hinge does not restrict the flipping of the top cover assembly. When the top cover assembly is rotated to the hovering position, the hinge limits the top cover assembly, thereby restricting the top cover assembly from continuing to rotate to the maximum unfolded position, thus achieving the hovering of the top cover assembly.

[0009] In this design, a stop is provided within the receiving groove. When the hinge part contacts the stop, the stop restricts the hinge part's rotation, thereby limiting the rotation of the upper cover assembly. For example, when the upper cover assembly rotates clockwise, it is in the opening direction. The stop restricts the hinge part from rotating clockwise, thus limiting the upper cover assembly's rotation from the suspended position to the fully extended position. In the suspended position, the bottom of the hinge part rests on the bottom of the receiving groove, and the side of the hinge part abuts against the stop. The bottom of the groove and the stop together restrict the hinge part's rotation. The bottom of the groove provides support and positioning for the hinge part, reducing the possibility of tilting and further improving the stability of the hinge part in limiting the upper cover assembly. Through this method, the upper cover assembly is suspended. In the suspended position, the user does not need to support the upper cover assembly by hand, which improves the convenience of using the grill.

[0010] When it is necessary to continue rotating the top cover assembly to the maximum unfolded position, the hinge can be pulled. The hinge moves within the receiving groove and separates from the stop. At this time, the stop no longer limits the hinge, thereby releasing the hinge from limiting the top cover assembly. When the top cover assembly rotates between the suspended position and the maximum unfolded position, the hinge rotates together with the top cover assembly.

[0011] From the bottom of the receiving groove to its opening, a portion of the stop bends away from the hinge. Because this portion of the stop is bent relative to the hinge, a part of the stop contacts the hinge, while the other part of the stop is spaced apart from it. This reduces the contact area between the stop and the hinge, making it easier to lift the hinge. Furthermore, when the hinge rotates with the top cover assembly, the bent portion of the stop is less likely to obstruct the hinge's rotation, allowing for rotation with a smaller lifting stroke.

[0012] In this design, the stop is located at the bottom of the receiving groove and is not lower than the bottom of the groove. When the hinge part is disengaged from the stop part, the hinge part is also disengaged from the bottom of the groove, making it easier to lift the hinge part.

[0013] In some technical solutions, the bottom of the stop is optionally integrally formed with the bottom of the groove, or the bottom of the stop is connected to the bottom of the groove.

[0014] The stop and the bottom of the groove can be designed as an integral structure, so that part of the stop serves as the bottom of the groove; or the stop and the bottom of the groove can be separate structures, but connected together.

[0015] In some technical solutions, the stop portion optionally includes a limiting surface and an arc-shaped clearance surface. The arc-shaped clearance surface is located on the side of the limiting surface adjacent to the slot. The arc-shaped clearance surface bends away from the hinge portion. When a part of the hinge portion is in contact with the limiting surface, the hinge portion and the arc-shaped clearance surface are spaced apart.

[0016] The stop portion has a limiting surface and an arc-shaped clearance surface on the side facing the hinge portion. When the hinge portion contacts the limiting surface, the limiting surface limits the hinge portion, thereby allowing the hinge portion to limit the upper cover assembly. After the hinge portion is lifted a certain distance, the side of the hinge portion separates from the limiting surface. At this time, the hinge portion can rotate with the upper cover assembly. Since the arc-shaped clearance surface is formed on the stop portion to avoid the hinge portion, the center line of the arc-shaped clearance surface can be set to coincide with the center line of the hinge portion during rotation. During the rotation of the hinge portion, interference between the hinge portion and the stop portion can be effectively prevented, ensuring that the hinge portion can rotate smoothly.

[0017] The arc-shaped clearance surface can also form a transition structure on the stop part, ensuring the connection stability between the stop part and the inner wall of the receiving groove.

[0018] In some technical solutions, the hinge portion is optionally provided with an oblong hole, and the base assembly is provided with a lower rotating shaft, which is inserted into the oblong hole so that the hinge portion can move and rotate relative to the lower rotating shaft.

[0019] In some technical solutions, optionally, the top of the limiting surface is lower than the axis of the lower rotating shaft.

[0020] The hinge can rotate relative to the base assembly along the axis of the lower rotating shaft. The limiting surface is lower than the axis of the lower rotating shaft. During the rotation of the hinge, the limiting surface is less likely to interfere with the rotation of the hinge, thus ensuring the stability of the hinge during rotation.

[0021] In some technical solutions, optionally, when the hinge is mounted on the bottom of the groove, at least a portion of the limiting surface is higher than the lowest point of the oblong hole.

[0022] During the flattening process, the interference of the limiting surface with the hinge is reduced, allowing the hinge to rotate smoothly.

[0023] In some technical solutions, optionally, when the hinge is installed at the bottom of the groove, the distance between the top of the limiting surface and the top of the waist-shaped hole is L1, and the distance between the top of the waist-shaped hole and the bottom of the waist-shaped hole is L2, in the direction perpendicular to the horizontal plane, where L1 < 0.5 × L2.

[0024] By reducing the limiting length of the limiting surface, it is easier to rotate the hinge.

[0025] In some technical solutions, the hinge portion is optionally provided with an upper rotating shaft, which is rotatably connected to the upper cover assembly. Along the length direction of the hinge portion, the central axis of the waist-shaped hole is offset from the central axis of the upper rotating shaft.

[0026] In some technical solutions, optionally, at least two stops are provided in the receiving groove, with adjacent stops spaced apart.

[0027] At least two stops are provided in the receiving groove. The at least two stops can simultaneously limit the hinge part and stably limit the hinge part to prevent the hinge part from shaking.

[0028] Compared to setting a wider stop in the receiving groove, this solution sets two adjacent stops at intervals, which can reduce the contact area between the stop and the hinge. When the hinge moves relative to the receiving groove, the friction force on the hinge can be reduced, thereby improving the smoothness of lifting or lowering the hinge.

[0029] In some technical solutions, optionally, a connecting part is also provided in the receiving groove, which connects two adjacent stop parts.

[0030] A connecting part is provided between two adjacent stops. The connecting part supports the two adjacent stops, preventing the stops from deforming under force and improving the structural stability of the stops. This allows the stops to stably limit the hinge.

[0031] In some technical solutions, optionally, at least two stops are provided on the top of the connecting part.

[0032] In some technical solutions, optionally, a support portion is provided at the top of the connecting portion, and a stop portion fits onto the support portion, with the bending curvature of the stop portion being the same as that of the support portion.

[0033] The bending curvature of the stop part is the same as that of the support part, which allows the stop part to fit tightly against the support part, and the support part to stably support the stop part, preventing the stop part from deforming under stress.

[0034] In some technical solutions, optionally, a portion of the connecting part protrudes from the stop portion, and the hinge portion rests on the bottom of the groove, in which case the hinge portion rests on a portion of the connecting part of the protruding stop portion.

[0035] When the hinge and the connecting part abut against each other, the hinge can be stably supported, reducing the tilt of the hinge and keeping the hinge in an upright position.

[0036] In some technical solutions, optionally, the width of the connecting part protruding from the stop part is smaller than the width of the groove bottom.

[0037] The width of the connecting part supporting the hinge is small to prevent food residue from accumulating above the connecting part.

[0038] In some technical solutions, optionally, when a portion of the hinged portion contacts the stop portion, the hinged portion and the connecting portion are spaced apart.

[0039] When the hinge part is in contact with the stop part, there is a gap between the hinge part and the connecting part. At this time, the hinge part is not in contact with the connecting part, that is, the thickness of the connecting part is less than the maximum thickness of the stop part. When the hinge part is lifted or lowered, it will not be subjected to the friction force of the connecting part, thereby improving the smoothness of lifting or lowering the hinge part.

[0040] In some technical solutions, optionally, a connecting port is provided between the bottom of the tank and the stop, the connecting port being used to discharge oil and residue from the tank.

[0041] Oil and residue in the receiving tank can flow out through the connecting port, preventing oil and residue from accumulating inside. This avoids affecting the smooth movement of the hinge and ensures that the top cover assembly can rotate smoothly relative to the base assembly through the hinge. Furthermore, the lack of oil and residue accumulation in the receiving tank prevents bacterial growth, ensuring the safety of the grill.

[0042] In some technical solutions, optionally, if one part of the hinge is placed on the bottom of the groove, the other part of the hinge faces the communication opening.

[0043] Instead of placing the connecting part with one bottom facing the bottom of the slot and the other bottom facing the connecting port, the connecting port is placed in an area other than the bottom of the hinge. This arrangement can reduce the size of the receiving slot and reduce the space occupied by the receiving slot in the grill.

[0044] In some technical solutions, the hinge portion is optionally provided with a first limiting portion, and the upper cover assembly is provided with a second limiting portion. When the upper cover assembly is in the hovering position and the maximum unfolded position, the second limiting portion abuts against the first limiting portion.

[0045] Before the top cover assembly rotates from the closed position to the hovering position, the second limiting part and the first limiting part are not in contact, and the hinge part does not obstruct the rotation of the top cover assembly. When the top cover assembly rotates to the hovering position, the second limiting part abuts against the first limiting part. At this time, the hinge part needs to be lifted first to separate the hinge part from the stop part. Then, the top cover assembly drives the hinge part to rotate through the mutual abutment of the first and second limiting parts.

[0046] In some technical solutions, optionally, the first limiting part is provided on the side of the hinge part away from the bottom of the groove, the first side of the hinge part faces the stop part, the second side of the hinge part is away from the stop part, and the distance between the first limiting part and the first side of the hinge part is smaller than the distance between the first limiting part and the second side of the hinge part.

[0047] A first limiting part is provided on the side of the hinge portion away from the bottom of the groove. The hinge portion is described in a first position as an example. The first side of the hinge portion faces the stop portion, and the second side of the hinge portion is away from the stop portion. The first limiting part and the first side of the hinge portion have a small distance, and the first limiting part and the second side of the hinge portion have a large distance.

[0048] When the first limiting part is in the above-mentioned position, the first limiting part is less likely to interfere with the structure of the upper cover assembly, thereby avoiding the first limiting part from affecting the rotation of the upper cover assembly.

[0049] In some technical solutions, optionally, when the cover assembly is in the closed position, the hovering position, and between the closed position and the hovering position, the length direction of the hinge is perpendicular to the horizontal direction.

[0050] In the closed and hovered positions, the hinge remains vertical, thus allowing the limiting surface to stably limit the hinge.

[0051] In some technical solutions, optionally, the hinged part is spaced apart from the bottom of the groove at the maximum unfolded position.

[0052] At the fully extended position, the hinge does not contact the bottom of the groove, and at this time the bottom of the groove is unlikely to obstruct the rotation of the hinge.

[0053] In some technical solutions, the base assembly may optionally have a vertical sidewall, with the side of the stop portion facing away from the hinge portion disposed on the vertical sidewall, and a step portion formed between the top of the stop portion and the vertical sidewall.

[0054] In some technical solutions, the grill may optionally have a lower baking pan mounted on a vertical side wall.

[0055] The vertical sidewalls of the receiving tank support the lower baking pan, making the receiving tank closer to the lower baking pan. This allows oil and residue to flow more easily into the receiving tank, preventing oil and residue from accumulating on the outside of the receiving tank.

Detailed Implementation

[0072] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model 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.

[0073] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0074] The following reference Figures 1 to 12 This invention describes a grilling machine provided according to some embodiments of the present invention.

[0075] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10As shown, in some embodiments of this utility model, a grill 100 is proposed. The grill 100 includes: a top cover assembly 110, a hinge part 121, and a base assembly 130. The hinge part 121 is rotatably connected to the top cover assembly 110, and the top cover assembly 110 rotates relative to the base assembly 130 between a closed position, a suspended position, and a fully extended position via the hinge part 121. The base assembly 130 is provided with a receiving groove 131, at least a portion of the hinge part 121 is located in the receiving groove 131, and the hinge part 121 is capable of moving and rotating within the receiving groove 131. In the closed position and the suspended position, at least a portion of the hinge part 121 rests on the bottom 128 of the receiving groove 131. A stop portion 160 is provided in the receiving groove 131. The distance between the stop portion 160 and the bottom of the receiving groove 131 is less than the distance between the stop portion 160 and the top of the receiving groove 131. The stop portion 160 is higher than or flush with the bottom of the groove 128. In the direction from the bottom of the receiving groove 131 to the opening 129 of the receiving groove 131, a part of the stop portion 160 bends away from the hinge portion 121. The upper cover assembly 110 is in the suspended position. When the hinge portion 121 is in contact with the stop portion 160, the hinge portion 121 restricts the upper cover assembly 110 from rotating from the suspended position to the maximum unfolded position. When the hinge portion 121 is separated from the stop portion 160, the hinge portion 121 can rotate with the upper cover assembly 110 between the suspended position and the maximum unfolded position.

[0076] Both the top cover assembly 110 and the base assembly 130 are connected to the hinge portion 121. The top cover assembly 110 rotates relative to the base assembly 130 via the hinge portion 121, thereby realizing the functions of opening and closing the cover. The top cover assembly 110 can rotate within a range of 0° and 180°. Of course, when the top cover assembly 110 is in the closed position, the angle of the top cover assembly 110 relative to the horizontal plane may be equal to 0° or slightly greater than 0°. When the top cover assembly 110 is in the fully extended position, the angle of the top cover assembly 110 relative to the horizontal plane may be equal to 180° or slightly less than 180°. The hovering position is located between the closed position and the fully extended position. For example, in the hovering position, the angle of the top cover assembly 110 relative to the horizontal plane is 90° or close to 90°.

[0077] A receiving groove 131 is machined on the base assembly 130. At least a portion of the hinge portion 121 is received in the receiving groove 131. The receiving groove 131 accommodates the hinge portion 121, preventing the hinge portion 121 from being excessively exposed on the surface of the grill 100, thereby improving the overall effect of the product.

[0078] The hinge 121 can move within the receiving groove 131, so that the upper cover assembly 110 can have a certain floating space relative to the base assembly 130. When the food in the cooking cavity expands due to heat, the upper cover assembly 110 can float upward, thereby increasing the space of the cooking cavity.

[0079] Before the top cover assembly 110 is flipped to the hovering position, the hinge 121 does not restrict the flipping of the top cover assembly 110. When the top cover assembly 110 is rotated to the hovering position, the hinge 121 limits the top cover assembly 110, thereby restricting the top cover assembly 110 from continuing to rotate to the maximum unfolded position, thus achieving the hovering of the top cover assembly 110.

[0080] In this design, a stop 160 is provided within the receiving groove 131. When the hinge 121 contacts the stop 160, the stop 160 restricts the hinge 121 from rotating, thereby restricting the rotation of the upper cover assembly 110. For example, when the upper cover assembly 110 rotates clockwise, it is in the opening direction. The stop 160 restricts the hinge 121 from rotating clockwise, at which time the hinge 121 restricts the upper cover assembly 110 from rotating from the suspended position to the fully unfolded position. In the suspended position, the bottom of the hinge 121 rests on the bottom 128 of the receiving groove 131, and the side of the hinge 121 abuts against the stop 160. The bottom 128 and the stop 160 together restrict the rotation of the hinge 121. The bottom 128 can support and position the hinge 121, reducing the possibility of the hinge 121 tilting and further improving the limiting stability of the hinge 121 on the upper cover assembly 110. In this way, the upper cover assembly 110 is suspended. In the suspended position, the user does not need to support the upper cover assembly 110 with his / her hand, which helps to improve the convenience of the user when using the grill 100.

[0081] When it is necessary to continue rotating the upper cover assembly 110 to the maximum unfolded position, the hinge part 121 can be pulled. The hinge part 121 moves within the receiving groove 131 and separates from the stop part 160. At this time, the stop part 160 no longer limits the hinge part 121, thereby releasing the limitation of the hinge part 121 on the upper cover assembly 110. When the upper cover assembly 110 rotates between the suspended position and the maximum unfolded position, the hinge part 121 rotates together with the upper cover assembly 110.

[0082] From the bottom of the receiving groove 131 to its opening, a portion of the stop portion 160 bends away from the hinge portion 121. Because this portion of the stop portion 160 is bent relative to the hinge portion 121, a portion of the stop portion 160 contacts the hinge portion 121, while the other portion of the stop portion 160 is spaced apart from the hinge portion 121. In this case, the contact area between the stop portion 160 and the hinge portion 121 can be reduced, making it easier to lift the hinge portion 121 upwards. Furthermore, when the hinge portion 121 rotates with the upper cover assembly 110, the bent portion of the stop portion 160 is less likely to obstruct the rotation of the hinge portion 121, allowing for rotation of the hinge portion 121 with a smaller upward stroke.

[0083] In this design, the stop 160 is located at the lower part of the receiving groove 131, and the stop 160 is not lower than the bottom of the groove 128. When the hinge 121 is disengaged from the stop 160, the hinge 121 is also disengaged from the bottom of the groove 128, making it easier to lift the hinge 121.

[0084] In some technical solutions, the bottom of the stop portion 160 may be integrally formed with the bottom of the groove 128, or the bottom of the stop portion 160 may be connected to the bottom of the groove 128.

[0085] The stop portion 160 and the groove bottom 128 can be configured as an integral structure, so that a part of the stop portion 160 serves as the groove bottom 128; or the stop portion 160 and the groove bottom 128 can be separate structures, but connected together.

[0086] Combination Figure 4 and Figure 10 As shown, in some embodiments, optionally, the stop portion 160 includes a limiting surface 125 and an arc-shaped clearance surface 126. The arc-shaped clearance surface 126 is located on the side of the limiting surface 125 adjacent to the slot 129. The arc-shaped clearance surface 126 is bent away from the hinge portion 121. When a part of the hinge portion 121 is in contact with the limiting surface 125, the hinge portion 121 and the arc-shaped clearance surface 126 are spaced apart.

[0087] The stop portion 160 has a limiting surface 125 and an arc-shaped clearance surface 126 on the side facing the hinge portion 121. When the hinge portion 121 contacts the limiting surface 125, the limiting surface 125 limits the hinge portion 121, thereby allowing the hinge portion 121 to limit the upper cover assembly 110. After the hinge portion 121 is lifted by a certain stroke, the side of the hinge portion 121 separates from the limiting surface 125. At this time, the hinge portion 121 can rotate with the upper cover assembly 110. Since the position on the stop portion 160 that avoids the hinge portion 121 forms an arc-shaped clearance surface, the center line of the arc-shaped clearance surface 126 can be set to coincide with the center line of the hinge portion 121 when it rotates. During the rotation of the hinge portion 121, interference between the hinge portion 121 and the stop portion 160 can be effectively prevented, ensuring that the hinge portion 121 can rotate smoothly.

[0088] The arc-shaped clearance surface 126 can also form a transition structure on the stop part 160, ensuring the connection stability between the stop part 160 and the inner wall of the receiving groove 131.

[0089] Combination Figure 4 , Figure 10 and Figure 12As shown, in some embodiments, the hinge portion 121 is optionally provided with an oblong hole 122, and the base assembly 130 is provided with a lower rotating shaft 181, which is inserted into the oblong hole 122 so that the hinge portion 121 can move and rotate relative to the lower rotating shaft 181.

[0090] like Figure 7 As shown, the grill also includes an upper hinge 123 and a lower hinge 124. The upper hinge 123 is rotatably connected to the upper cover assembly 110 via an upper pivot 182, and the upper hinge 123 and the hinge portion 121 are rotatably connected via the upper pivot 182. The lower hinge 124 is connected to the base assembly 130, and the lower hinge 124 and the hinge portion 121 are rotatably connected via a lower pivot 181. The hinge portion 121 is provided with an oblong hole 122, and the pivot on the lower hinge 124 is inserted into the oblong hole 122, allowing the hinge portion 121 to move relative to the lower hinge 124 within the receiving groove 131. This arrangement eliminates the need for openings in the base assembly 130, thereby preventing oil and residue from entering the interior of the base assembly 130.

[0091] In some embodiments, the top of the limiting surface 125 is optionally lower than the axis of the lower rotating shaft 181.

[0092] The hinge 121 can rotate relative to the base assembly 130 along the axis of the lower rotating shaft 181. The limiting surface 125 is lower than the axis of the lower rotating shaft 181. During the rotation of the hinge 121, the limiting surface 125 is less likely to interfere with the rotation of the hinge 121, thus ensuring the stability of the hinge 121 during rotation.

[0093] In some embodiments, optionally, when the hinge 121 is mounted on the bottom of the groove 128, at least a portion of the limiting surface 125 is higher than the lowest point of the oblong hole 122.

[0094] When the limiting surface 125 is higher than the lowest point of the oblong hole 122, the hinge part 121 is not easy to rotate relative to the limiting surface 125, thereby ensuring the stable limiting of the hinge part 121 by the limiting surface 125.

[0095] In some embodiments, optionally, when the hinge 121 rests on the bottom of the groove 128, it is positioned in a direction perpendicular to the horizontal plane. Figure 10 (The arrow at H in the middle points to) The distance between the top of the limiting surface 125 and the top of the waist-shaped hole 122 is L1, and the distance between the top of the waist-shaped hole 122 and the bottom of the waist-shaped hole 122 is L2, where L1 < 0.5 × L2.

[0096] The limiting surface 125 is lower than the middle of the waist-shaped hole 122. Within this range, the limiting surface 125 can ensure the limiting stability of the hinge part 121, and also improve the smoothness when lifting the hinge part 121.

[0097] Combination Figure 4 , Figure 10 and Figure 11 As shown, in some embodiments, optionally, the hinge portion 121 is provided with an upper rotating shaft 182, which is rotatably connected to the upper cover assembly 110, along the length direction of the hinge portion 121 ( Figure 10 (The arrow at point H points in the middle) indicates that the central axis H1 of the waist-shaped hole 122 is misaligned with the central axis H2 of the upper rotating shaft 182.

[0098] The hinge 121 can rotate around the central axis of the waist-shaped hole 122, and the axes of the waist-shaped hole 122 and the upper rotating shaft 182 are misaligned, which helps to improve the limiting stability of the hinge 121 on the upper cover assembly 110.

[0099] like Figure 8 As shown, in some embodiments, optionally, at least two stop portions 160 are provided in the receiving groove 131, with adjacent two stop portions 160 spaced apart.

[0100] At least two stops 160 are provided in the receiving groove 131. The at least two stops 160 can simultaneously limit the hinge 121 and stably limit the hinge 121 to prevent the hinge 121 from shaking.

[0101] Compared to providing a wider stop 160 in the receiving groove 131, this solution provides two adjacent stop 160s spaced apart, which reduces the contact area between the stop 160 and the hinge 121. When the hinge 121 moves relative to the receiving groove 131, the friction force on the hinge 121 can be reduced, thereby improving the smoothness of lifting or lowering the hinge 121.

[0102] Combination Figure 8 and Figure 10 As shown, in some embodiments, optionally, a connecting portion 127 is also provided in the receiving groove 131, and the connecting portion 127 connects two adjacent stop portions 160.

[0103] A connecting part 127 is provided between two adjacent stop parts 160. The connecting part 127 supports the two adjacent stop parts 160 to prevent the stop parts 160 from deforming when subjected to force, thereby improving the structural stability of the stop parts 160 and enabling the stop parts 160 to stably limit the hinge part 121.

[0104] In some embodiments, optionally, at least two stops 160 are provided on the top of the connecting portion 127.

[0105] At least two stop portions 160 are provided on the top of the connecting portion 127. The connecting portion 127 supports the stop portions 160. When the stop portions 160 are under force, the position of the stop portions 160 is not easily shifted, thus ensuring the limiting stability of the stop portions 160 on the hinge portion 121.

[0106] In some embodiments, optionally, a support portion 190 is provided on the top of the connecting portion 127, a stop portion 160 is attached to the support portion 190, and the bending curvature of the stop portion 160 is the same as the bending curvature of the support portion 190.

[0107] The bending radius of the stop portion 160 is the same as that of the support portion 190, so that the stop portion 160 can fit tightly against the support portion 190. The support portion 190 can stably support the stop portion 160 and prevent the stop portion 160 from deforming when subjected to force.

[0108] In some embodiments, optionally, a portion of the connecting portion 127 protrudes from the stop portion 160, and the hinge portion 121 rests on the bottom of the groove 128, in which case the hinge portion 121 rests on a portion of the connecting portion 127 of the protruding stop portion 160.

[0109] The width of the connecting portion 127 is greater than the width of the stop portion 160. Therefore, a part of the connecting portion 127 extends out of the bottom of the stop portion 160, so that the extended part of the connecting portion 127 can support the hinge portion 121, further improving the support stability of the hinge portion 121 and preventing the hinge portion 121 from tilting.

[0110] In some embodiments, the width of the connecting portion 127 protruding from the stop portion 160 is optionally smaller than the width of the groove bottom.

[0111] The width of the connecting part 127 supporting the hinge part 121 is small to prevent food residue from accumulating above the connecting part 127.

[0112] Combination Figure 8 and Figure 10 As shown, in some embodiments, optionally, when a portion of the hinge portion 121 contacts the stop portion 160, the hinge portion 121 and the connecting portion 127 are spaced apart.

[0113] When the hinge portion 121 is in contact with the stop portion 160, there is a gap between the hinge portion 121 and the connecting portion 127. At this time, the hinge portion 121 is not in contact with the connecting portion 127. That is, the thickness of the connecting portion 127 is less than the maximum thickness of the stop portion 160. When the hinge portion 121 is lifted or lowered, it will not be subjected to the frictional force of the connecting portion 127, thereby improving the smoothness of the hinge portion 121 when it is lifted or lowered.

[0114] Combination Figure 6 and Figure 10As shown, in some embodiments, the hinge portion 121 is optionally movable between a first position and a second position. In the first position, the hinge portion 121 is engaged with the stop portion 160, and in the second position, the hinge portion 121 is disengaged from the stop portion 160. In the first position, the bottom of the hinge portion 121 abuts against the groove bottom 128.

[0115] The hinge portion 121 is movable within the receiving groove 131. When the hinge portion 121 moves to the first position, the bottom of the hinge portion 121 abuts against the bottom 128 of the receiving groove 131, and the side of the hinge portion 121 abuts against the stop portion 160. The bottom 128 and the stop portion 160 together restrict the rotation of the hinge portion 121, further improving the positioning stability of the hinge portion 121 on the upper cover assembly 110.

[0116] When the hinge portion 121 moves to the second position, the hinge portion 121 separates from the stop portion 160, so the hinge portion 121 can rotate synchronously with the upper cover assembly 110.

[0117] Combination Figure 4 and Figure 6 As shown, in some embodiments, optionally, a communication port 134 is provided between the bottom of the tank 128 and the stop portion 160, the communication port 134 being used to discharge oil and residue from the receiving tank 131.

[0118] Oil and residue in the receiving tank 131 can flow out through the connecting port 134, preventing oil and residue from accumulating in the receiving tank 131. This avoids affecting the smooth movement of the hinge 121 and ensures that the upper cover assembly 110 can rotate smoothly relative to the base assembly 130 through the hinge 121. Furthermore, the lack of oil and residue accumulation in the receiving tank 131 prevents bacterial growth and ensures the safe use of the grill 100.

[0119] The base assembly 130 is provided with an oil drain hole 133, and the connecting port 134 is connected to the oil drain hole 133. The oil in the receiving tank is discharged to the outside of the grill 100 through the connecting port 134 and the oil drain hole 133 in sequence.

[0120] The base assembly 130 is provided with a control unit 140, which includes a control panel and / or control knobs. The control unit 140 and the oil drain hole 133 are located on opposite sides of the base assembly 130.

[0121] Figure 4 The arrows in the diagram are used to indicate the path through which the oil is discharged.

[0122] A control unit 140 is provided on the base assembly 130. Users can control the functions of the grill 100 through the control unit 140. For example, users can press the physical or virtual buttons on the control panel to control the function, or users can rotate the control knob to adjust the function.

[0123] The control unit 140 is usually located on the front of the grill 100. In this solution, the control unit 140 and the oil drain hole 133 are respectively located on opposite sides of the base assembly 130. Therefore, the oil drain hole 133 is located on the back of the grill 100, and the oil and residue flow out of the grill 100 from the back of the grill 100, thus preventing the oil and residue from contacting the items on both sides of the grill 100.

[0124] Combination Figure 4 and Figure 6 As shown, in some embodiments, optionally, a portion of the hinge 121 rests under the bottom of the groove 128, while another portion of the hinge 121 faces the communication port 134.

[0125] A portion of the bottom of the hinge 121 faces the bottom of the groove 128, and another portion faces the connecting port 134. Instead of setting the connecting port 134 in an area other than the bottom of the hinge 121, this arrangement can reduce the size of the receiving groove 131 and reduce the space occupied by the receiving groove 131 in the grill 100.

[0126] Combination Figure 9 and Figure 10 As shown, in some embodiments, the hinge portion 121 is optionally provided with a first limiting portion 171, and the upper cover assembly 110 is provided with a second limiting portion 172. When the upper cover assembly 110 is in the hover position, the maximum unfolded position, and between the hover position and the maximum unfolded position, the second limiting portion 172 abuts against the first limiting portion 171.

[0127] Before the cover assembly 110 rotates from the closed position to the hovered position, the second limiting part 172 is not in contact with the first limiting part 171, and at this time the hinge part 121 does not obstruct the rotation of the cover assembly 110. When the cover assembly 110 rotates to the hovered position, the second limiting part 172 abuts against the first limiting part 171. At this time, the hinge part 121 needs to be lifted first to separate the hinge part 121 from the stop part 160. Then, the cover assembly 110 drives the hinge part 121 to rotate through the mutual abutment of the first limiting part 171 and the second limiting part 172.

[0128] When the top cover assembly 110 rotates from the hovering position to the maximum unfolded position, the second limiting part 172 pushes the first limiting part. During the rotation from the maximum unfolded position to the hovering position, the top cover assembly 110 drives the hinge part 121 to rotate synchronously through the frictional force at the pivot position.

[0129] Combination Figure 9 and Figure 10 As shown, in some embodiments, optionally, the first limiting part 171 is provided on the side of the hinge part 121 away from the bottom of the groove 128, the first side of the hinge part 121 faces the stop part 160, the second side of the hinge part 121 is away from the stop part 160, and the distance between the first limiting part 171 and the first side of the hinge part 121 is smaller than the distance between the first limiting part 171 and the second side of the hinge part 121.

[0130] A first limiting part 171 is provided on the side of the hinge portion 121 away from the bottom of the groove 128. The hinge portion 121 is described in a first position as an example. The first side of the hinge portion 121 faces the stop portion 160, and the second side of the hinge portion 121 is away from the stop portion 160. The first limiting part 171 and the first side of the hinge portion 121 have a small distance, and the first limiting part 171 and the second side of the hinge portion 121 have a large distance.

[0131] When the first limiting part 171 is in the above-mentioned position, the first limiting part 171 is less likely to interfere with the structure of the upper cover assembly 110, thereby avoiding the first limiting part 171 from affecting the rotation of the upper cover assembly 110.

[0132] In some embodiments, optionally, when the cover assembly 110 is in the closed position, the hovering position, and between the closed position and the hovering position, the length direction of the hinge portion 121 is perpendicular to the horizontal direction.

[0133] In the closed position and the hovering position, the hinge 121 remains in a vertical state, thereby enabling the limiting surface 125 to stably limit the hinge 121.

[0134] In some embodiments, the hinge portion 121 is optionally spaced apart from the groove bottom 128 in the maximum extended position.

[0135] In the fully extended position, the hinge 121 is not in contact with the bottom of the groove 128, and at this time the bottom of the groove 128 is unlikely to obstruct the rotation of the hinge 121.

[0136] In some embodiments, the base assembly 130 may optionally have a vertical sidewall 135, a stop portion 160 is disposed on the side of the vertical sidewall 135 away from the hinge portion 121, and a step portion 136 is formed between the top of the stop portion 160 and the vertical sidewall 135.

[0137] The stop portion 160 protrudes from the vertical sidewall 135, and a step portion 136 is formed between the top of the stop portion 160 and the vertical sidewall 135. That is, the stop portion 160 does not extend to the top of the vertical sidewall 135, leaving a large space above the receiving groove 131. During the process of food falling into the receiving groove 131, the stop portion 160 is not likely to obstruct the food, thereby preventing the food from accumulating above the receiving groove 131.

[0138] In some embodiments, the grill 100 may optionally have a lower grill pan 200 mounted on a vertical side wall 135.

[0139] The vertical sidewall 135 of the receiving tank 131 supports the lower baking pan 200, making the receiving tank 131 closer to the lower baking pan 200, so that oil and residue can flow into the receiving tank 131 more easily, and preventing oil and residue from accumulating on the outside of the receiving tank 131.
