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 invented a grill with a detachable top cover assembly. The grill is electrically connected to the top cover assembly and the base assembly via a coupler. The coupler includes an upper connector electrically connected to the top cover assembly and a lower connector electrically connected to the base assembly. When the base assembly is used with the top cover assembly removed, water can easily fall into the lower connector, which poses a certain safety hazard. Utility Model Content

[0004] Therefore, it is necessary to provide a grill that can reduce the safety hazards of water entering the lower connector.

[0005] A grill includes a base assembly, a top cover assembly, a hinge assembly, a coupler, and a drive assembly. The top cover assembly is rotatably and detachably connected to the base assembly via the hinge assembly. The coupler includes an upper connector electrically connected to the top cover assembly and a lower connector electrically connected to the base assembly. When the top cover assembly is connected to the base assembly, the upper connector and the lower connector are electrically connected. The lower connector has a lower connection port that mates with the upper connector. The drive assembly is disposed on the base assembly and applies a force to the lower connector to rotate the lower connector so that the lower connection port faces the outer periphery of the base assembly when the top cover assembly is detached from the base assembly.

[0006] The grill provided in this application, by setting a drive component, allows the lower connector to rotate so that the lower connection port faces the outer periphery of the base component when the upper cover component is removed. This prevents water that falls naturally due to gravity from entering the lower connection port and causing water to enter the lower connector. It can be seen that by setting a drive component, the lower connector automatically rotates when the upper cover component is removed, avoiding the lower connection port facing upwards, thereby greatly reducing the safety hazard of water entering the lower connector.

[0007] In one embodiment, the base assembly is provided with a hinge groove, the sidewall of which is provided with a movable hole extending in the vertical direction, and the lower connector is provided with a rotating shaft that extends into the movable hole and can move along the movable hole. When the rotating shaft moves to the upper end of the movable hole, the lower connector can rotate to face the outer periphery of the base assembly.

[0008] In this way, by setting the movable hole, the hinge assembly can move up and down relative to the base assembly, so that when cooking with the lid closed, the food can lift the lid assembly, avoiding the lid assembly pressing the food too firmly.

[0009] In one embodiment, the drive assembly includes a lifting drive and a rotating drive, the lifting drive applying an upward force to the lower connector, and the rotating drive applying a force to the lower connector to rotate towards the outer periphery of the base assembly.

[0010] In this way, the lifting drive can control the lower connector to move to the upper end of the hinge slot, and correspondingly, the rotating shaft moves to the upper end of the movable hole, thereby facilitating the rotation drive to control the rotation of the lower connector.

[0011] In one embodiment, the lifting drive includes a drive rod and an elastic element, the elastic element applying a force to the drive rod to move the drive rod upward, thereby causing the drive rod to push the lower connector upward.

[0012] Thus, when the upper cover assembly is connected to the base assembly, the gravity of the upper cover assembly will compress the elastic element, causing the elastic element to accumulate a certain elastic force. When the upper cover assembly is removed from the base assembly, the elastic force of the elastic element can automatically control the lower connector to move upward. At the same time, with the action of the rotation drive, the lower connector can quickly and automatically rotate to face the outer periphery of the base assembly without the need for manual operation by the user, which is very convenient to use.

[0013] In one embodiment, the base assembly has a receiving cavity, the upper end of the receiving cavity has a limiting hole communicating with the hinge groove, the drive rod passes through the limiting hole, and the elastic element is disposed in the receiving cavity and pushes the drive rod from the lower side.

[0014] In this way, the accommodating cavity provides installation space for the drive rod and the elastic element, and the limiting hole guides the movement of the drive rod, ensuring that the drive rod always pushes the lower connector upward, thereby enabling more efficient control of the rotation of the lower connector.

[0015] In one embodiment, the outer wall of the drive rod is provided with a limiting rib, the limiting rib is located in the accommodating cavity and stops at the lower end of the limiting hole, and the upper end of the elastic member abuts against the lower side of the limiting rib.

[0016] Thus, the setting of the limiting rib not only prevents the drive rod from coming out of the receiving cavity, but also provides a force point for the elastic element, which facilitates the installation of the elastic element.

[0017] In one embodiment, the lower end of the accommodating cavity is provided with an installation port and a cover plate that closes the installation port, and the lower end of the elastic member abuts against the cover plate.

[0018] Thus, the drive rod and elastic element can be installed into the cavity through the mounting port at the lower end of the cavity. It can be seen that the mounting port greatly facilitates the installation of the drive rod and elastic element, and the cover plate can prevent the drive rod and elastic element from falling out from the lower end of the cavity.

[0019] In one embodiment, when the lower connector is in an upright position with the lower connection port facing upward, the drive rod abuts against the force-bearing position of the lower connector, the force-bearing position being located at the end of the lower connector away from the lower connection port, and horizontally located on the side of the rotating shaft near the center of the base assembly.

[0020] Thus, under the combined action of the drive rod and the rotation drive component, the lower connector can easily rotate around the pivot, thereby making it easy for the lower connector to rotate so that the lower connection port faces the outer periphery of the base assembly.

[0021] In one embodiment, the lower connector has a guide surface at one end away from the lower connection port. The guide surface is an arc-shaped surface and extends to the side wall of the lower connector. The upper end of the drive rod has a pushing surface, which is an arc-shaped surface or a spherical surface.

[0022] In this way, the pushing surface can move along the guide surface, that is, the upper end of the drive rod will not obstruct the rotation of the lower connector. Thus, under the combined action of the drive rod and the rotation drive component, the lower connector can move upward and rotate around the axis, so that the lower connector can smoothly rotate to the outer periphery of the lower connection port facing the base assembly.

[0023] In one embodiment, the rotation drive is a torsion spring, and the base assembly is further provided with a limiting groove extending in the vertical direction. The torsion spring is sleeved on the outside of the rotating shaft, one end of the torsion spring abuts against the lower connector, and the other end extends into the limiting groove and abuts against the side wall of the limiting groove.

[0024] Thus, by using a torsion spring to provide the force to rotate the lower connector, it is ensured that the lower connector can rotate automatically when the upper cover assembly is removed. In this embodiment, a limiting groove extending in the vertical direction is provided, and one end of the torsion spring extends into the limiting groove, ensuring that the installation of the torsion spring does not affect the vertical movement of the lower connector.

[0025] In one embodiment, the outer wall of the lower connector is provided with a slot, and one end of the torsion spring abuts against the side wall of the slot.

[0026] In this way, one end of the torsion spring is housed in the slot, resulting in a very compact structure and making it less likely for the torsion spring to detach from the lower connector.

[0027] In one embodiment, when the upper cover assembly is detached from the base assembly, the drive assembly rotates the lower connector so that the lower connection port faces horizontally.

[0028] In this way, when the top cover assembly is removed from the base assembly, the lower connector faces horizontally, which can better prevent water from entering the lower connector.

[0029] In one embodiment, the grill has a cooking cavity, and an avoidance opening is provided on the side of the upper end of the hinge groove away from the cooking cavity. The bottom wall of the avoidance opening forms a support portion, which supports the side wall of the lower connector when the upper cover assembly is removed from the base assembly.

[0030] Thus, when the top cover assembly is detached from the base assembly, the support portion provides excellent support for the lower connector, maintaining the stability of the lower connector's position. Furthermore, when the top cover assembly is connected to the base assembly and unfolded to one side of the base assembly, the support portion can also support the lower connector, thereby ensuring the stability of the electrical connection between the top cover assembly and the base assembly.

[0031] In one embodiment, the hinge assembly includes an upper hinge and a lower hinge, the upper hinge being rotatably connected to the upper cover assembly, the upper connector being disposed on the upper hinge, the lower hinge being disposed on the base assembly, the lower connector being disposed on the lower hinge, and the upper hinge and the lower hinge being detachably connected.

[0032] Thus, the upper and lower hinges can be used to detachably connect the upper cover assembly and the base assembly.

[0033] In one embodiment, there are two upper hinges and two lower hinges, which are arranged in a one-to-one correspondence. The hinge assembly also includes a connecting rod connecting the two upper hinges. The base assembly is provided with two hinge slots, and the two lower hinges are arranged in the two hinge slots in a one-to-one correspondence.

[0034] This embodiment features two hinge slots, with space between them to accommodate the oil inlet of the lower baking pan, resulting in a very compact grill structure. A connecting rod ensures the synchronous rotation of the two upper hinges.

[0035] In one embodiment, the lower connector is disposed in one of the lower hinges, the upper connector is disposed in the corresponding upper hinge, and there are two drive components, with the two drive components corresponding to the two lower hinges.

[0036] Thus, when the top cover assembly is removed from the base assembly, the two lower hinges can rotate synchronously, thereby waterproofing the lower connector. At the same time, it is easy to align the two upper hinges and two lower hinges when installing the top cover assembly, thus facilitating the installation of the top cover assembly.

[0037] In one embodiment, the hinge assembly is an integral structure, the hinge assembly is rotatably connected to the upper cover assembly, the upper connector is disposed within the hinge assembly, and the lower connector is disposed on the base assembly.

[0038] Thus, the upper cover assembly and the base assembly can be connected through the upper and lower connectors. The hinge assembly structure of the integrated structure is simpler and easier to install. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0058] Please see Figures 1 to 12 This application provides a grill, including a base assembly 10, a top cover assembly 20, a hinge assembly 30, a coupler 70, and a drive assembly 50. The top cover assembly 20 is rotatably and detachably connected to the base assembly 10 via the hinge assembly 30. The coupler 70 includes an upper connector 72 electrically connected to the top cover assembly 20 and a lower connector 71 electrically connected to the base assembly 10. When the top cover assembly 20 is connected to the base assembly 10, the upper connector 72 and the lower connector 71 are electrically connected. The lower connector 71 has a lower connection port 711 that mates with the upper connector 72. The drive assembly 50 is disposed on the base assembly 10 and applies a force to the lower connector 71 so that when the top cover assembly 20 is removed from the base assembly 10, the lower connector 71 rotates to face the lower connection port 711 toward the outer periphery of the base assembly 10. Thus, when the upper cover assembly 20 is removed from the base assembly 10, the lower connector 711 faces the outer periphery of the base assembly 10. As a result, water that falls naturally due to gravity will not enter the lower connector 711 and cause water to enter the lower connector 71. It can be seen that by setting the drive assembly 50, the lower connector 71 automatically rotates when the upper cover assembly 20 is removed, avoiding the lower connector 711 facing upward, thereby greatly reducing the safety hazard of water entering the lower connector 71.

[0059] Further, please see Figures 6 to 8 The base assembly 10 is provided with a hinge groove 111, and the side wall of the hinge groove 111 is provided with a movable hole 112 extending in the vertical direction. The lower connector 71 is provided with a rotating shaft 712, which extends into the movable hole 112 and can move along the movable hole 112. When the rotating shaft 712 moves to the upper end of the movable hole 112, the lower connector 71 can rotate so that the lower connection port 711 faces the outer periphery of the base assembly 10. In this way, the lower connector 71 can move up and down within the hinge groove 111, at which time the lower connector 71 is in an upright state. When the rotating shaft 712 moves to the upper end of the movable hole 112, the lower connector 71 can rotate at the upper end of the hinge groove 111, thereby the lower connector 71 can rotate from the upright state to the flat state. 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. Figures 1 to 3 As shown, when the lower connector 71 is in the upright position, the lower connection port 711 faces upward; as Figures 4 to 6 As shown, when the lower connector 71 is in a flat position, the lower connection port 711 faces the outer periphery of the base assembly 10 and is positioned away from the cooking cavity 102. In this embodiment, by providing a movable hole 112 extending in the vertical direction, the lower connector 71 can move up and down relative to the base assembly 10, so that the upper cover assembly 20 and the base assembly 10 can maintain an electrical connection. Thus, when cooking with the lid closed (i.e., when the upper cover assembly 20 is closed on the base assembly 10 for cooking), 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 expand easily, such as pancakes.

[0060] Please see Figure 5 In one embodiment, when the upper cover assembly 20 is removed from the base assembly 10, the drive assembly rotates the lower connector 71 so that the lower connection port 711 faces horizontally. Thus, when the upper cover assembly 20 is removed from the base assembly 10, the lower connection port 711 faces horizontally, which better prevents water from entering the lower connector 71.

[0061] Please see Figure 4 and Figure 5The hinge groove 111 has a clearance opening 1111 on the side away from the cooking cavity 102 at its upper end. The bottom wall of the clearance opening 1111 forms a support portion 1112. When the upper cover assembly 20 is removed from the base assembly 10, the support portion 1112 supports the side wall of the lower connector 71. Thus, when the upper cover assembly 20 is removed from the base assembly 10, the support portion 1112 provides good support for the lower connector 71, maintaining the stability of the lower connector 71's position. Furthermore, when the upper cover assembly 20 is connected to the base assembly 10 and the upper cover assembly 20 is unfolded to one side of the base assembly 10, the support portion 1112 can also support the lower connector 71, thereby ensuring the stability of the electrical connection between the upper cover assembly 20 and the base assembly 10. In this embodiment, when the upper cover assembly 20 is removed from the base assembly 10, the lower connector 71 can be rotated so that the lower connection opening 711 faces the horizontal direction, resulting in better waterproofing. However, this is not the only embodiment. In other embodiments, when the upper cover assembly is removed from the base assembly, the lower connection port may also be at a certain angle relative to the horizontal direction, facing upwards or downwards.

[0062] Please see Figure 5 , Figure 8 , Figure 9 and Figure 11 Furthermore, the drive assembly 50 includes an upward drive member 51 and a rotation drive member 52. The upward drive member 51 applies an upward force to the lower connector 71, and the rotation drive member 52 applies a force to the lower connector 71 to rotate towards the outer periphery of the base assembly 10. In this way, the upward drive member 51 can control the lower connector 71 to move upward to the upper end of the hinge groove 111, and correspondingly, the rotating shaft 712 moves to the upper end of the movable hole 112, thereby facilitating the rotation drive member 52 to control the lower connector 71 to rotate towards the outer periphery of the base assembly 10.

[0063] like Figure 5 and Figure 11 As shown, the lifting drive 51 includes a drive rod 511 and an elastic element 512. The elastic element 512 applies a force to the drive rod 511, causing the drive rod 511 to move upward and push the lower connector 71 upward. Thus, when the upper cover assembly 20 is connected to the base assembly 10, the gravity of the upper cover assembly 20 compresses the elastic element 512, causing the elastic element 512 to accumulate a certain elastic force. When the upper cover assembly 20 is removed from the base assembly 10, the elastic force of the elastic element 512 can automatically control the lower connector 71 to move upward. At the same time, in conjunction with the action of the rotation drive 52, the lower connector 71 can quickly and automatically rotate to face the outer periphery of the base assembly 10 without the need for manual operation by the user, which is very convenient to use.

[0064] Furthermore, the base assembly 10 is provided with a receiving cavity 113, and the upper end of the receiving cavity 113 is provided with a limiting hole 1131 that communicates with the hinge groove 111. The drive rod 511 passes through the limiting hole 1131, and the elastic element 512 is disposed in the receiving cavity 113 and pushes against the drive rod 511 from the lower side. In this way, the receiving cavity 113 provides installation space for the drive rod 511 and the elastic element 512, and the limiting hole 1131 guides the movement of the drive rod 511, ensuring that the drive rod 511 always pushes against the lower connector 71 upwards, thereby controlling the rotation of the lower connector 71 more efficiently. In this embodiment, the receiving cavity 113 is formed in the bottom shell 11.

[0065] Furthermore, the outer wall of the drive rod 511 is provided with a limiting rib 5111, which is located inside the receiving cavity 113 and stops at the lower end of the limiting hole 1131. The upper end of the elastic member 512 abuts against the lower side of the limiting rib 5111. In this way, the setting of the limiting rib 5111 not only prevents the drive rod 511 from coming out of the receiving cavity 113, but also provides a force point for the elastic member 512, which facilitates the installation of the elastic member 512.

[0066] Furthermore, the lower end of the accommodating cavity 113 is provided with an installation port and a cover plate 114 that closes the installation port, and the lower end of the elastic element 512 abuts against the cover plate 114. Thus, the drive rod 511 and the elastic element 512 can be installed into the accommodating cavity 113 through the installation port at the lower end of the accommodating cavity 113. It is evident that the installation port greatly facilitates the installation of the drive rod 511 and the elastic element 512, and the cover plate 114 prevents the drive rod 511 and the elastic element 512 from falling out of the lower end of the accommodating cavity 113. In one embodiment, the cover plate 114 is connected to the lower end of the accommodating cavity 113 by fasteners, but this is not a limitation. In other embodiments, the cover plate 114 can also be snapped onto the lower end of the accommodating cavity 113, and this application does not impose any restrictions on this. In this embodiment, the elastic element 512 is a compression spring, which has good elasticity and is inexpensive. However, this is not a limitation. In other embodiments, the elastic element can also be a tension spring or an elastic rope, as long as the elastic element can provide an upward elastic force to the drive rod.

[0067] Please see Figure 1 , Figure 3 and Figure 8 When the lower connector 71 is in the upright position with the lower connection port 711 facing upwards, the drive rod 511 abuts against the force-bearing position 710 of the lower connector 71. The force-bearing position 710 is located at the end of the lower connector 71 away from the lower connection port 711, and is horizontally located on the side of the rotating shaft 712 near the center of the base assembly 10. Thus, under the combined action of the drive rod 511 and the rotation drive member 52, the lower connector 71 can easily rotate around the rotating shaft 712, thereby easily rotating the lower connector 711 to the outer periphery of the base assembly 10 with the lower connection port 711 facing upwards.

[0068] Please see Figure 3, Figure 5 and Figure 11 The lower connector 71 has a guide surface 713 at the end away from the lower connection port 711. The guide surface 713 is an arc-shaped surface and extends from the force-bearing position 710 to the side wall of the lower connector 71. The upper end of the drive rod 511 has a push surface 5112, which is an arc-shaped or spherical surface. In this way, the push surface 5112 can move along the guide surface 713, that is, the upper end of the drive rod 511 will not obstruct the rotation of the lower connector 71. Thus, under the combined action of the drive rod 511 and the rotation drive member 52, the lower connector 71 can move upward and rotate around the rotation axis 712, so that the lower connector 71 can smoothly rotate to the outer periphery of the lower connection port 711 facing the base assembly 10.

[0069] Please see Figure 6 , Figure 10 and Figure 11 In this embodiment, the rotation drive 52 is a torsion spring, and the base assembly 10 is also provided with a limiting groove 115 extending in the vertical direction. The torsion spring is sleeved on the outside of the rotating shaft 712, with one end of the torsion spring abutting against the lower connector 71 and the other end extending into the limiting groove 115 and abutting against the side wall of the limiting groove 115. Thus, by providing the force to rotate the lower connector 71 through the torsion spring, it is ensured that the lower connector 71 can automatically rotate when the upper cover assembly 20 is removed. This embodiment, by providing a limiting groove 115 extending in the vertical direction, with one end of the torsion spring extending into the limiting groove 115, ensures that the installation of the torsion spring will not affect the vertical movement of the lower connector 71. It is understood that the depth of the limiting groove 115 needs to ensure that one end of the torsion spring always extends into the limiting groove 115 when the lower connector 71 moves vertically, so as to ensure that the torsion spring can work normally.

[0070] In this embodiment, one end of the torsion spring that extends into the limiting groove 115 is rolled into a loop. In this way, the end of the torsion spring can better abut against the inner wall of the limiting groove 115, thereby reducing the swaying of the torsion spring.

[0071] Furthermore, the outer wall of the lower connector 71 is provided with a slot 715, and one end of the torsion spring abuts against the side wall of the slot 715. In this way, one end of the torsion spring is housed within the slot 715, resulting in a very compact structure, and the torsion spring is not easily dislodged from the lower connector 71. Of course, in other embodiments, the outer wall of the lower connector 71 may also be provided with a protrusion, and one end of the torsion spring abuts against one side of the protrusion, as long as the torsion spring can provide the lower connector 71 with a force that rotates the lower connection port 711 toward the outer periphery of the base assembly 10.

[0072] like Figure 12As shown, in one embodiment, the hinge assembly 30 includes an upper hinge 32 and a lower hinge 31. The upper hinge 32 is rotatably connected to the upper cover assembly 20, and an upper connector 72 is disposed on the upper hinge 32. The lower hinge 31 is disposed on the base assembly 10, and the lower connector 71 is disposed on the lower hinge 31. The upper hinge 32 and the lower hinge 31 are detachably connected. Thus, the upper cover assembly 20 and the base assembly 10 can be detachably connected through the cooperation of the upper hinge 32 and the lower hinge 31.

[0073] Furthermore, both the upper hinge 32 and the lower hinge 31 are provided in pairs, and are arranged one-to-one. The hinge assembly 30 also includes a connecting rod 34 connecting the two upper hinges 32. The base assembly 10 is provided with two hinge slots 111, and the two lower hinges 31 are arranged one-to-one in 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 table surface, 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 providing two hinge slots 111, space can be left between the two hinge slots 111 to accommodate the oil inlet 121 of the lower baking pan 12, making the structure of the grill very compact. By providing the connecting rod 34, the synchronicity of the rotation of the two upper hinges 32 can be ensured.

[0074] Furthermore, the lower connector 71 is disposed in one of the lower hinges 31, and the upper connector 72 is disposed in the corresponding upper hinge 32. Two drive assemblies 50 are provided, each corresponding to one of the two lower hinges 31. Thus, when the upper cover assembly 20 is removed from the base assembly 10, the two lower hinges 31 can rotate synchronously, thereby providing waterproofing for the lower connector 71. Simultaneously, aligning the two upper hinges 32 and the two lower hinges 31 is convenient when installing the upper cover assembly 20, facilitating its installation.

[0075] It is understood that in this embodiment, only one pair of upper hinges 32 and lower hinges 31 are provided with the above-mentioned coupler 70, and a locking member can be provided between the other pair of upper hinges 32 and lower hinges 31 to lock the upper hinges 32 and lower hinges 31. In this way, the upper hinges 32 and lower hinges 31 can be locked by the locking member, thereby maintaining the stability of the electrical connection between the upper connector 72 and the lower connector 71.

[0076] In the above embodiments, the hinge assembly 30 includes an upper hinge 32 and a lower hinge 31, which are separate structures. Of course, in other embodiments, the hinge assembly can also be an integral structure. Further, the hinge assembly is rotatably connected to the upper cover assembly. The upper connector is located inside the hinge assembly, and the lower connector is located on the base assembly. Thus, the upper cover assembly and the base assembly can be connected through the upper and lower connectors. The integral structure of the hinge assembly is simpler and easier to install. Further, the hinge assembly may include two spaced-apart hinge bodies and a connecting rod connecting the two hinge bodies. The base assembly has two hinge slots corresponding to the two hinge bodies. The upper connector is located on one of the hinge bodies, and correspondingly, the lower connector is located in the corresponding hinge slot and is detachably connected to the upper connector. The other hinge body is detachably installed in the other hinge slot.

[0077] 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.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively 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.
