Grill machine

Abstract

This application relates to a grill, including a base assembly, a top cover assembly, and a hinge assembly. The base assembly has a hinge groove. One end of the hinge assembly is rotatably connected to the top cover assembly, and the other end is movably disposed within the hinge groove. The side wall of the hinge groove has a first movable hole extending in the vertical direction. The side wall of the hinge assembly has a retractable locking member. When the top cover assembly is connected to the base assembly, the locking member extends into the first movable hole and can move along the first movable hole. The top wall of the first movable hole has a limiting surface. The base assembly has an unlocking member that can move closer to or away from the limiting surface along the extension direction of the locking member. When the unlocking member moves closer to the limiting surface, the locking member can leave the first movable hole, allowing the hinge assembly to disengage from the base assembly. When the unlocking member moves away from the limiting surface, the limiting surface can block the locking member, preventing the hinge assembly from disengaging from the base assembly. During normal use, the grill can use the limiting surface to limit the locking member, preventing the connection between the top cover assembly and the base assembly from loosening.

Description

Technical Field

[0001] This application relates to the field of cooking appliances technology, and in particular to a grill. Background Technology

[0002] Grills typically consist of a base assembly and a top cover assembly. Traditional grills have non-removable top and base assemblies, making them inconvenient to use. With technological advancements, grills with detachable top covers have emerged. These grills allow for easy removal of the top cover assembly, making cleaning very convenient.

[0003] The applicant previously invented a grill, in which a coupler is provided on the hinge assembly. The coupler includes an upper connector and a lower connector, which cooperate to achieve mechanical and electrical connection between the upper cover assembly and the base assembly. However, this type of grill is prone to causing the upper cover assembly to be directly removed due to excessive force when opening the lid, or causing the upper cover assembly to move unnecessarily relative to the base assembly, resulting in poor electrical contact and poor conductivity, leading to a poor user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a grill that can prevent undesirable loosening of the connection between the top cover assembly and the base assembly.

[0005] A grill includes a base assembly, a top cover assembly, and a hinge assembly. The base assembly has a hinge groove. One end of the hinge assembly is rotatably connected to the top cover assembly, and the other end is movably disposed within the hinge groove. The side wall of the hinge groove has a first movable hole extending in the vertical direction. The side wall of the hinge assembly has a retractable locking member. When the top cover assembly is connected to the base assembly, the locking member extends into the first movable hole and can move along the first movable hole. The top wall of the first movable hole has a limiting surface. The base assembly has an unlocking member that can move closer to or further away from the limiting surface along the extension direction of the locking member. When the unlocking member moves closer to the limiting surface, the locking member can leave the first movable hole, allowing the hinge assembly to disengage from the base assembly. When the unlocking member moves away from the limiting surface, the limiting surface can block the locking member, preventing the hinge assembly from disengaging from the base assembly.

[0006] The grill provided in this application, by setting a limiting surface and an unlocking component, allows the unlocking component to move away from the limiting surface during normal use. The limiting surface then restricts the locking component, preventing the hinge assembly from detaching from the base assembly, thus keeping the top cover assembly in a non-removable state and preventing loosening of the connection between the top cover assembly and the base assembly. When it is necessary to remove the top cover assembly, simply move the unlocking component closer to the limiting surface. This allows the locking component to move away from the first movable hole, making the top cover assembly detachable and allowing for easy removal and cleaning.

[0007] In one embodiment, the unlocking member has a guide surface on the side facing the hinge slot, and the guide surface is inclined from bottom to top toward the hinge slot.

[0008] Thus, the guide surface can guide the movement of the locking member, allowing the locking member to smoothly disengage from the first movable hole. The guide surface has a simple structure, good guiding effect, and is easy to process.

[0009] In one embodiment, the unlocking member is connected to a first elastic member, which applies a force to the unlocking member to move it away from the limiting surface.

[0010] Thus, when the top cover assembly needs to be removed, the unlocking component is moved closer to the limiting surface by external force. When the external force is removed, the unlocking component can automatically move away from the limiting surface under the elastic force of the first elastic component. This avoids the user forgetting to control the movement of the unlocking component, leaving the top cover assembly in a detachable state, which could easily cause the top cover assembly to become loose.

[0011] In one embodiment, the base assembly has a mounting portion with a through mounting hole. The unlocking member includes an unlocking portion, a connecting portion, and a limiting portion. The connecting portion passes through the mounting hole, and the unlocking portion and the limiting portion are respectively located at both ends of the connecting portion. The first elastic member is sleeved on the outside of the connecting portion, and its two ends abut against the limiting portion and the side of the mounting portion away from the limiting surface.

[0012] Thus, the mounting holes on the mounting section guide the movement of the unlocking component, making it easier to control the position switching of the unlocking component. The unlocking component and the first elastic element have a compact structure and are easy to install.

[0013] In one embodiment, the base assembly is provided with an operating member and a second elastic member. The operating member is used to control the unlocking member to move toward the limiting surface, and the second elastic member is used to reset the operating member.

[0014] In this way, the user controls the movement of the unlocking part by applying force to the operating part. After the user removes the external force applied to the operating part, the second elastic element can automatically reset the operating part, thus facilitating the next operation. At the same time, the force applied to the unlocking part is removed from the operating part, so that the unlocking part automatically moves away from the limiting surface under the elastic force of the first elastic element.

[0015] In one embodiment, the operating member has a pushing surface that is inclined relative to the movement direction of the operating member, and the unlocking member has a pushing surface that cooperates with the pushing surface that is inclined relative to the movement direction of the unlocking member. The movement direction of the operating member and the movement direction of the unlocking member are perpendicular to each other.

[0016] Thus, the structure is very compact. The direction of linear motion can be changed by the cooperation of the push surface and the push surface, so that the unlocking part moves in a direction perpendicular to the direction of movement of the operating part. Thus, the operating part and the unlocking part can be set on the same side of the hinge slot, and the unlocking part can be set inside the base assembly, while the operating part can be set on the side wall of the base assembly. This makes it easy for the user to apply force to the operating part when the top cover assembly needs to be removed.

[0017] In one embodiment, the actuation element is a button or push knob.

[0018] Buttons or push-buttons have a simple structure and are easy to operate.

[0019] In one embodiment, the hinge assembly further includes a third elastic element that applies force to the locking element to cause one end of the locking element to extend out of the hinge assembly.

[0020] Thus, under the elastic force of the third elastic element, the locking element can remain in a state where one end protrudes from the hinge assembly, so that the end of the locking element can cooperate with the limiting surface, so that when the unlocking element moves away from the limiting surface, the top cover assembly cannot be removed from the base assembly, thereby ensuring the stability of the electrical connection between the top cover assembly and the base assembly.

[0021] In one embodiment, the upper side of the locking member extending from one end of the hinge assembly is provided with a stop surface that mates with the limiting surface, the stop surface being a plane or a cylindrical surface.

[0022] In this way, the locking element can be prevented from being pressed into the hinge assembly and from coming out of the first moving hole by the cooperation of the stop surface and the limiting surface.

[0023] In one embodiment, the lower side of the end of the locking member extending out of the hinge assembly is provided with a guide surface, which is a bevel, an arc, or a spherical surface.

[0024] Thus, when installing the top cover assembly, the side wall of the hinge groove can press against the guide surface, causing the locking member to be pressed into the hinge assembly. When the locking member moves to face the first movable hole, under the elastic force of the third elastic member, the locking member can automatically extend into the first movable hole, thereby smoothly installing the hinge assembly into the hinge groove and completing the connection between the top cover assembly and the base assembly.

[0025] In one embodiment, the locking member extends from one end of the hinge assembly and has a mating surface, the mating surface connecting the top surface of the locking member and the end surface of the locking member, the mating surface being an arc-shaped surface or a spherical surface.

[0026] In this way, when the top cover assembly is removed, the mating surface and the guide surface of the unlocking component come into contact. The mating surface is an arc-shaped or spherical surface, which can prevent the sharp end of the locking component from causing injury, and the mating surface slides more smoothly along the guide surface.

[0027] In one embodiment, the hinge assembly has a receiving groove with an opening at one end. The unlocking member is disposed in the receiving groove and one end can extend out from the opening. The outer peripheral wall of the locking member has an anti-rotation surface, which is a plane. The inner wall of the receiving groove is at least partially adapted to the outer peripheral wall of the locking member to restrict the rotation of the locking member.

[0028] In this way, the locking member can only extend and retract relative to the hinge assembly, but cannot rotate, thus ensuring that the stop surface of the locking member faces upward and the guide surface faces downward, so that the locking member cannot disengage from the first moving hole when the unlocking member moves away from the limiting surface.

[0029] In one embodiment, when the unlocking member moves away from the limiting surface and the locking member moves to the upper end of the first movable hole, the locking member can rotate within the first movable hole so that the hinge assembly can rotate relative to the base assembly to the other end facing the outer periphery of the base assembly.

[0030] Thus, when the top cover assembly is in a non-removable state, the hinge assembly can not only move up and down relative to the base assembly, but also rotate relative to the base assembly. Therefore, the grill can include a closed state where the top cover assembly is closed on the base assembly, an open state where the top cover assembly is upright relative to the base assembly, and an unfolded state where the top cover assembly is flipped to one side of the base assembly. Furthermore, in the closed state, the top cover assembly can move up and down relative to the base assembly, making the grill more flexible to use.

[0031] In one embodiment, the grill further includes a coupler for electrically connecting the upper cover assembly and the base assembly. The coupler includes an upper connector on the hinge assembly and a lower connector on the base assembly. When the upper cover assembly is connected to the base assembly, the upper connector and the lower connector are electrically connected. When the upper cover assembly is removed from the base assembly, the upper connector and the lower connector are electrically disconnected. The hinge slot sidewall is also provided with a second movable hole extending in the vertical direction. The lower connector is provided with a rotating shaft that extends into the second movable hole and can move along the second movable hole. When the rotating shaft moves to the upper end of the second movable hole, the rotating shaft can rotate within the second movable hole, so that the hinge assembly can rotate relative to the base assembly to the other end facing the outer periphery of the base assembly.

[0032] Thus, when the upper cover assembly is connected to the base assembly, the upper and lower connectors are electrically connected, thereby achieving electrical connection between the electronic components within the upper cover assembly and the electronic components within the base assembly. This application ensures a stable connection between the upper and lower connectors by setting a limiting surface to block the locking element, thereby guaranteeing good electrical conductivity between the upper cover assembly and the base assembly. When the upper cover assembly is removed from the base assembly, the upper and lower connectors are electrically disconnected, ensuring that the coupler does not interfere with the removal of the upper cover assembly from the base assembly.

[0033] In one embodiment, the hinge assembly includes two hinge bodies spaced apart and a connecting rod connecting the two hinge bodies. One of the hinge bodies is provided with the locking member, and the other hinge body is provided with the upper connector. The base assembly is provided with two hinge slots, and the first movable hole and the second movable hole are respectively provided in the two hinge slots.

[0034] Thus, by setting up two hinge bodies spaced apart, on the one hand, space is left between the two hinge bodies to accommodate the oil inlet of the baking pan, making the grill structure very compact; on the other hand, the locking element and the upper connector can be placed in different hinge bodies, resulting in a very reasonable spatial arrangement and preventing mutual interference. By setting up a connecting rod, the synchronous rotation of the two hinge bodies is ensured, making it easy to align the two hinge bodies and the two hinge slots when installing the top cover assembly, thus facilitating the connection of the top cover assembly to the base assembly.

[0035] In one embodiment, the hinge assembly includes a hinge body, the locking member and the upper connector are respectively disposed on both sides of the hinge assembly, the base assembly is provided with a corresponding hinge groove, and the first movable hole and the second movable hole are respectively disposed on opposite sides of the hinge groove.

[0036] This results in a simpler structure, and the installation positions of the locking components and couplers will not interfere with each other. Attached Figure Description

[0060] Please see Figures 1 to 14 This application provides a grill, including a base assembly 10, a top cover assembly 20, and a hinge assembly 30. The top cover assembly 20 is rotatably and vertically connected to the base assembly 10 via the hinge assembly 30. Specifically, the base assembly 10 has a hinge groove 111, one end of the hinge assembly 30 is rotatably connected to the top cover assembly 20, and the other end is movably disposed within the hinge groove 111. The side wall of the hinge groove 111 has a first movable hole 112 extending in the vertical direction, and the side wall of the hinge assembly 30 has a retractable locking member 41. When the top cover assembly 20 is connected to the base assembly 10, the locking member 41 extends into the first movable hole 112 and can move along the first movable hole 112. The top wall of the first movable hole 112 has a limiting surface 1121, and the base assembly 10 has an unlocking member 51 that can move closer to or away from the limiting surface 1121 along the extension direction of the locking member 41. Figure 6 As shown, when the unlocking member 51 approaches the limiting surface 1121, the unlocking member 51 can guide the locking member 41 to move into the hinge assembly 30, thereby allowing the locking member 41 to disengage from the first movable hole 112, so that the hinge assembly 30 can be disengaged from the base assembly 10. Thus, the upper cover assembly 20 can be removed from the base assembly 10. Figure 7As shown, when the unlocking member 51 is away from the limiting surface 1121, the limiting surface 1121 can block the locking member 41, thus preventing the locking member 41 from disengaging from the first movable hole 112. Consequently, the hinge assembly 30 cannot detach from the base assembly 10, and the top cover assembly 20 cannot be removed from the base assembly 10. By setting the limiting surface 1121 and the unlocking member 51, the grill can, during normal use, limit the locking member 41 by using the limiting surface 1121 to prevent the hinge assembly 30 from detaching from the base assembly 10. That is, the top cover assembly 20 is in a non-removable state, thereby preventing the connection between the top cover assembly 20 and the base assembly 10 from becoming loose. When it is necessary to remove the top cover assembly 20, simply control the unlocking member 51 to move closer to the limiting surface 1121. The unlocking member 51 can then be used to move the locking member 41 to disengage from the first movable hole 112, thus putting the top cover assembly 20 in a detachable state. This allows the top cover assembly 20 to be removed smoothly, making it easy to clean the top cover assembly 20.

[0061] Please see Figure 8 It is understood that the base assembly 10 includes a bottom shell 11 and a lower baking pan 12, and the upper cover assembly 20 includes an upper shell 21 and an upper baking pan 22. When the upper cover assembly 20 is closed on the base assembly 10, the upper baking pan 22 and the lower baking pan 12 enclose the cooking cavity 102. During cooking with the lid closed (i.e., when the upper cover assembly 20 is closed on the base assembly 10 for cooking), since the locking member 41 can move along the first movable hole 112, the hinge assembly 30 can move up and down within the hinge groove 111. Therefore, the food can lift the upper cover assembly 20, preventing the upper cover assembly 20 from pressing the food too firmly. This grill is suitable for cooking foods that easily expand, such as pancakes.

[0062] Please see Figure 5 and Figure 6 The unlocking member 51 has a guide surface 511 on the side facing the hinge groove 111, and the guide surface 511 is inclined from bottom to top towards the hinge groove 111. Thus, when the unlocking member 51 approaches the limiting surface 1121, the hinge assembly 30 is lifted upwards, and the locking member 41 moves upwards accordingly. When the locking member 41 moves to the point where its end contacts the guide surface 511, as the locking member 41 continues to move upwards, it is pressured by the limiting surface 1121 and moves inwards into the hinge assembly 30. This allows the locking member 41 to disengage from the first movable hole 112, and the hinge assembly 30 to disengage from the hinge groove 111, allowing the upper cover assembly 20 to be easily removed. The unlocking member 51, by providing the aforementioned guide surface 511, guides the movement of the locking member 41, enabling it to smoothly disengage from the first movable hole 112. The guide surface 511 has a simple structure, good guiding effect, and is easy to manufacture.

[0063] Furthermore, the unlocking member 51 is connected to a first elastic member 52, which applies a force to the unlocking member 51 to move it away from the limiting surface 1121. Thus, when the upper cover assembly 20 needs to be removed, the unlocking member 51 is moved closer to the limiting surface 1121 by external force. When the external force is removed, the unlocking member 51 automatically moves away from the limiting surface 1121 under the elastic force of the first elastic member 52. This prevents the upper cover assembly 20 from being left in a detachable state due to the user forgetting to control the movement of the unlocking member 51, which could lead to undesirable loosening of the upper cover assembly 20.

[0064] Furthermore, the base assembly 10 is provided with a mounting portion 13, which has a through mounting hole 131. The unlocking member 51 includes an unlocking portion 512, a connecting portion 513, and a limiting portion 514. The connecting portion 513 passes through the mounting hole 131, and the unlocking portion 512 and the limiting portion 514 are respectively located at both ends of the connecting portion 513. The unlocking portion 512 is located at the end of the mounting portion 13 near the limiting surface 1121 and can stop against the mounting portion 13. The limiting portion 514 is located on the side of the mounting portion 13 away from the limiting surface 1121. The first elastic member 52 is sleeved on the outside of the connecting portion 513, and its two ends abut against the limiting portion 514 and the side of the mounting portion 13 away from the limiting surface 1121. In this way, the mounting hole 131 on the mounting portion 13 guides the movement of the unlocking member 51, making the position switching of the unlocking member 51 easier to control. The unlocking member 51 and the first elastic member 52 have a compact structure and are easy to install.

[0065] like Figure 6 As shown, the guide surface 511 is provided on the unlocking part 512, thereby unlocking the locking member 41 by means of the unlocking part 512.

[0066] In this embodiment, the first elastic element 52 is a compression spring, which has a simple structure and is easy to install. However, it is not limited to this. In other embodiments, the first elastic element can also be a tension spring, elastic rope, or other elastic element, as long as the first elastic element applies a force to the unlocking element to move it away from the limiting surface.

[0067] In this embodiment, the unlocking part 512 is integrally formed on one end of the connecting part 513, and the limiting part 514 is detachably connected to the other end of the connecting part 513. Further, the limiting part 514 can be configured as a screw, thus facilitating the installation of the first elastic member 52 and the unlocking member 51. However, this is not a limitation; in other embodiments, the limiting part can also be integrally formed on one end of the connecting part, and the unlocking part can be detachably connected to one end of the connecting part, which also allows for convenient installation of the first elastic member and the unlocking member. Alternatively, both the limiting part and the unlocking part can be detachably connected to the end of the connecting part; this application does not impose any restrictions on this.

[0068] Please see Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 The base assembly 10 is provided with an operating member 61 and a second elastic member 62. The operating member 61 is used to control the unlocking member 51 to move towards the limiting surface 1121, and the second elastic member 62 is used to reset the operating member 61. In this way, the user controls the movement of the unlocking member 51 by applying force to the operating member 61. After the user removes the external force applied to the operating member 61, the second elastic member 62 can make the operating member 61 automatically reset, thus facilitating the next operation. At the same time, the operating member 61 removes the force applied to the unlocking member 51, so that the unlocking member 51 automatically moves away from the limiting surface 1121 under the elastic force of the first elastic member 52.

[0069] Please see Figures 10 to 13 The operating member 61 has a pushing surface 615, which is inclined relative to the movement direction of the operating member 61. The unlocking member 51 has a receiving surface 515 that cooperates with the pushing surface 615, which is also inclined relative to the movement direction of the unlocking member 51. The movement direction of the operating member 61 and the movement direction of the unlocking member 51 are perpendicular. This results in a very compact structure. The cooperation between the receiving surface 515 and the pushing surface 615 changes the direction of linear motion, allowing the unlocking member 51 to move in a direction perpendicular to the movement direction of the operating member 61. Thus, the operating member 61 and the unlocking member 51 can be located on the same side of the hinge groove 111, and the unlocking member 51 can be located inside the base assembly 10. The operating member 61 can be located on the side wall of the base assembly 10, making it easy for the user to apply force to the operating member 61 when the upper cover assembly 20 needs to be removed. In this embodiment, the receiving surface 515 is located on the unlocking part 512, but it is not limited to this; the receiving surface 515 can also be located at other positions on the unlocking member 51, and this application does not impose any restrictions on this. The operating member 61 has a push plate 611 on one side, and the pushing surface 615 is set on the push plate 611. In this way, the pushing surface 615 and the pushed surface 515 are close to each other, so that the operating member 61 can easily push the unlocking member 51 to move.

[0070] In one embodiment, the operating element 61 is a button. Pressing the button controls the movement of the unlocking element 51, making operation very convenient. Furthermore, after releasing the button, it automatically resets under the elastic force of the second elastic element 62. However, this is not a limitation. In other embodiments, the operating element can also be a push knob. Pushing the push knob controls the movement of the unlocking element, also making operation very convenient. Furthermore, after releasing the push knob, it automatically resets under the elastic force of the second elastic element. It is understood that when the operating element is a push knob, the movement direction of the operating element and the movement direction of the unlocking element can be set in the same direction. This simplifies the control of the unlocking element by the operating element and further simplifies the structure. Of course, the movement directions of the operating element and the unlocking element can also be different. A transmission structure that can change the movement direction can be provided between them, allowing the operating element to control the unlocking element to move towards the limiting surface. This application does not impose any limitations on this.

[0071] like Figure 9 As shown, in this embodiment, the second elastic element 62 is a compression spring, which abuts against the base assembly 10 and the operating member 61. However, it is not limited to this. In other embodiments, the second elastic element can also be a tension spring, elastic rope, or other elastic element, as long as the second elastic element can automatically reset the operating member after the force applied to it is removed.

[0072] Furthermore, such as Figures 2 to 4 As shown, the bottom shell 11 includes a bottom shell body 113 and a bottom shell cover 114. The bottom shell body 113 and the bottom shell cover 114 together form a hinge groove 111. Specifically, the bottom wall of the hinge groove 111 is formed in the bottom shell body 113, and the side wall of the hinge groove 111 is formed in the bottom shell cover 114. Correspondingly, a first movable hole 112 is provided on the bottom shell cover 114. Further, the mounting part 13 is integrally formed on the bottom shell cover 114. The bottom shell body 113 and the bottom shell cover 114 can be fixedly connected by fasteners or by snap-fit, and this application does not limit this. In this embodiment, the bottom shell 11 includes a separate bottom shell body 113 and a bottom shell cover 114, which is beneficial for installing the unlocking member 51 and the operating member 61 on the bottom shell 11.

[0073] Please see Figures 5 to 7 The hinge assembly 30 is also provided with a third elastic member 42, which applies force to the locking member 41 so that one end of the locking member 41 extends out of the hinge assembly 30. Thus, under the elastic force of the third elastic member 42, the locking member 41 can be kept in the state where one end extends out of the hinge assembly 30, so that the end of the locking member 41 can cooperate with the limiting surface 1121, so that when the unlocking member 51 moves away from the limiting surface 1121, the upper cover assembly 20 cannot be removed from the base assembly 10, thereby ensuring the stability of the electrical connection between the upper cover assembly 20 and the base assembly 10.

[0074] In this embodiment, the third elastic element 42 is a compression spring, which has a simple structure and is easy to install. Figure 6 and Figure 7 As shown, in one embodiment, the hinge assembly 30 has a receiving groove 311 with an opening at one end. The third elastic member 42 and the unlocking member 51 are both located within the receiving groove 311, and one end of the unlocking member 51 can extend from the opening. The opening is stepped, and one section of the unlocking member 51 is also stepped. Thus, one end of the unlocking member 51 can extend from the opening, while the other end is confined within the receiving groove 311, preventing the unlocking member 51 from dislodging from the receiving groove 311. In this embodiment, the other end of the receiving groove 311 has an installation port with a sealing member 43 to seal the third elastic member 42 within the receiving groove 311. During installation, first insert the unlocking member 51 and the third elastic member 42 into the receiving groove 311 through the mounting port, and then install the sealing member 43, so that the mounting port is blocked by the sealing member 43. In this way, the unlocking member 51 and the third elastic member 42 are installed in the hinge assembly 30, and the two ends of the third elastic member 42 abut against the unlocking member 51 and the sealing member 43, so that the elastic force of the third elastic member 42 can allow one end of the unlocking member 51 to extend out of the hinge assembly 30. Of course, the unlocking member 51 and the third elastic member 42 can also be installed in the hinge assembly 30 in other ways. For example, the unlocking member and the third elastic member can be installed in the receiving groove from the opening side of the receiving groove, and the end of the receiving groove away from the opening is not provided with a mounting port. Furthermore, a stop member can be provided at the opening of the receiving groove to limit the length of the unlocking member extending out of the receiving groove opening. In this way, the unlocking member can also be movably installed in the hinge assembly, and the elastic force of the third elastic member can allow one end of the unlocking member to extend out of the hinge assembly. In addition, there may be other ways to install the unlocking device and the third elastic element, which are not limited in this application.

[0075] Please see Figure 6 , Figure 7 and Figure 14 Furthermore, the upper side of the locking member 41 extending from one end of the hinge assembly 30 is provided with a stop surface 411 that cooperates with the limiting surface 1121. The stop surface 411 is a plane or a cylindrical surface. In this way, by cooperating with the limiting surface 1121, the locking member 41 can be prevented from being pressed into the hinge assembly 30 and the locking member 41 can be prevented from coming out of the first movable hole 112.

[0076] Furthermore, the lower side of the end of the unlocking member 51 extending out of the hinge assembly 30 is provided with a guide surface 412, which is a bevel, an arc surface, or a spherical surface. Thus, when the top cover assembly 20 is installed, the side wall of the hinge groove 111 can press against the guide surface 412, causing the locking member 41 to be pressed into the hinge assembly 30. When the locking member 41 moves to face the first movable hole 112, under the elastic force of the third elastic member 42, the locking member 41 can automatically extend into the first movable hole 112, thereby smoothly installing the hinge assembly 30 into the hinge groove 111, completing the connection between the top cover assembly 20 and the base assembly 10.

[0077] Furthermore, the locking member 41 has a mating surface 413 extending from one end of the hinge assembly 30. The mating surface 413 connects the top surface and the end face of the locking member 41, that is, the mating surface 413 connects the stop surface 411 and the guide surface 412. The mating surface 413 is an arc-shaped surface or a spherical surface. Thus, when the upper cover assembly 20 is removed, the mating surface 413 contacts the guide surface 511 of the unlocking member 51. The fact that the mating surface 413 is an arc-shaped or spherical surface can prevent the sharp end of the locking member 41 from causing injury, and the mating surface 413 slides more smoothly along the guide surface 511. One or more mating surfaces 413 may be provided at the end of the locking member 41, and this application does not limit this.

[0078] Further, please see Figure 6 and Figure 14 The outer peripheral wall of the locking member 41 is provided with an anti-rotation surface 414, which is planar. The inner wall of the receiving groove 311 is at least partially adapted to the outer peripheral wall of the locking member 41 to restrict the rotation of the locking member 41. In this way, the locking member 41 can only extend and retract relative to the hinge assembly 30, but cannot rotate, thereby ensuring that the stop surface 411 of the locking member 41 faces upward and the guide surface 412 faces downward, so that when the unlocking member 51 moves away from the limiting surface 1121, the locking member 41 cannot disengage from the first movable hole 112. In this embodiment, the locking member 41 is provided with two anti-rotation surfaces 414, which are located on the upper and lower sides of the locking member 41, respectively. However, it is not limited to this. In other embodiments, only one anti-rotation surface 414 may be provided, or more than two anti-rotation surfaces 414 may be provided. This application does not limit this, as long as the receiving groove 311 and the anti-rotation surface 414 cooperate to restrict the rotation of the locking member 41.

[0079] Furthermore, when the unlocking member 51 moves away from the limiting surface 1121 and the locking member 41 moves to the upper end of the first movable hole 112, the locking member 41 can rotate within the first movable hole 112, so that the hinge assembly 30 can rotate relative to the base assembly 10 to the other end facing the outer periphery of the base assembly 10, thereby allowing the upper cover assembly 20 to be flipped to one side of the base assembly 10, i.e., the upper cover assembly 20 is in the unfolded state, such as... Figure 15As shown. At this time, the base assembly 10 can be used for open-lid cooking, and the upper baking tray 22 of the upper cover assembly 20 can also be used for cooking food. It can be seen that when the upper cover assembly 20 is in the non-removable state, the hinge assembly 30 can not only move up and down relative to the base assembly 10, but also rotate relative to the base assembly 10. Therefore, the grill can include a closed state in which the upper cover assembly 20 is closed on the base assembly 10, an open state in which the upper cover assembly 20 is upright relative to the base assembly 10, and an unfolded state in which the upper cover assembly 20 is flipped to one side of the base assembly 10 (e.g., Figure 15 As shown), and in the closed state, the upper cover assembly 20 can move up and down relative to the base assembly 10, thus making the grill more flexible to use.

[0080] like Figure 5 As shown, the grill also includes a coupler 70 that electrically connects the upper cover assembly 20 and the base assembly 10. The coupler 70 includes an upper connector 72 located on the hinge assembly 30 and a lower connector 71 located on the base assembly 10. When the upper cover assembly 20 is connected to the base assembly 10, the upper connector 72 and the lower connector 71 are electrically connected, thus achieving electrical connection between the electronic components in the upper cover assembly 20 and the electronic components in the base assembly 10. This application ensures a stable connection between the upper connector 72 and the lower connector 71 by setting a limiting surface 1121 to block the locking member 41, thereby ensuring good electrical conductivity between the upper cover assembly 20 and the base assembly 10. When the upper cover assembly 20 is removed from the base assembly 10, the upper connector 72 and the lower connector 71 are disconnected, ensuring that the coupler 70 does not affect the removal of the upper cover assembly 20 from the base assembly 10.

[0081] Please see Figure 5 and Figure 16 The lower connector 71 is movably disposed within the hinge groove 111. The side wall of the hinge groove 111 is also provided with a second movable hole 115 extending in the vertical direction. The lower connector 71 is provided with a rotating shaft 711, which extends into the second movable hole 115 and can move along the second movable hole 115. When the rotating shaft 711 moves to the upper end of the second movable hole 115, the rotating shaft 711 can rotate within the second movable hole 115, so that the hinge assembly 30 can rotate relative to the base assembly 10 to the other end facing the outer periphery of the base assembly 10, thereby allowing the upper cover assembly 20 to rotate as shown. Figure 15 The unfolded state shown.

[0082] Please see Figure 2 , Figure 3 and Figure 5Furthermore, the hinge assembly 30 includes two hinge bodies 31, which are spaced apart. One hinge body 31 is provided with a locking element 41, and the other hinge body 31 is provided with an upper connector 72. The base assembly 10 has two hinge slots 111 corresponding to the two hinge bodies 31. The first movable hole 112 and the second movable hole 115 are respectively provided on the side walls of the two hinge slots 111. When the upper cover assembly 20 is opened to the upright position, the liquid (oil or water) on the upper baking pan 22 will flow downward under its own gravity. In order to prevent the liquid from falling onto the countertop, an oil inlet 121 is usually provided on the lower baking pan 12 to catch the liquid flowing down from the upper baking pan 22. In this embodiment, by setting two hinge bodies 31 spaced apart, on the one hand, space can be left between the two hinge bodies 31 to accommodate the oil inlet 121 of the lower baking pan 12, making the structure of the grill very compact. On the other hand, the locking member 41 and the upper connector 72 can be set in different hinge bodies 31 respectively, and the spatial arrangement is very reasonable and there will be no mutual interference.

[0083] Further, please see Figure 3 and Figure 5 The hinge assembly 30 also includes a connecting rod 32, which connects the two hinge bodies 31. In this way, by setting the connecting rod 32, the synchronicity of the rotation of the two hinge bodies 31 can be ensured, so that when installing the cover assembly 20, the two hinge bodies 31 and the two hinge slots 111 can be easily aligned, thereby facilitating the connection of the cover assembly 20 to the base assembly 10.

[0084] Of course, in other embodiments, the hinge assembly may consist of only a hinge body, resulting in a simpler structure. The locking element and the upper connector can be respectively disposed on both sides of the hinge body, and a corresponding hinge groove is provided on the base assembly. The first movable hole and the second movable hole are respectively disposed on opposite sides of the hinge groove. This ensures that the installation positions of the locking element and the coupler do not interfere with each other. Accordingly, the oil inlet of the lower baking pan can be located on the outside of the hinge assembly, as long as the oil inlet can catch the liquid flowing from the upper baking pan.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
