Description

Technical Field

[0001] The present application relates to the technical field of household kitchen appliances, and in particular to a frying and grilling machine. Background Art

[0002] The grilling machine generally comprises a base assembly and an upper cover assembly, wherein the upper cover assembly and the base assembly are rotatably connected via a hinge assembly, so that the upper cover assembly can be opened or closed relative to the base assembly.

[0003] In some grilling machines, when the upper cover assembly is in the closed state, the hinge assembly can move up and down relative to the base assembly, so that the food can lift the upper cover assembly to a floating state. In this type of grilling machine, when the upper cover assembly is in the upright state, the connection strength between the hinge assembly and the base assembly is weak, and the hinge assembly cannot provide effective support for the upper cover assembly, which makes it easy for the upper cover assembly to tip over. Utility Model Content

[0004] Based on this, it is necessary to provide a grilling machine that can improve the stability of the upper cover assembly when it is erected.

[0005] A grilling machine, comprising: a base assembly, an upper cover assembly and a hinge assembly, wherein the upper cover assembly is rotatably connected to the base assembly via the hinge assembly, the grilling machine having a first open cover state in which the upper cover assembly stands upright relative to the base assembly, the hinge assembly being fixedly provided with a lower rotating shaft, the base assembly being provided with a movable hole, the lower rotating shaft being passed through the movable hole, and the lower rotating shaft being able to move up and down in the movable hole, the lower rotating shaft being provided with a limiting protrusion, and the lower end of the movable hole being provided with a limiting groove, when the grilling machine is in the first open cover state, the lower rotating shaft is located at the lower end of the movable hole, the limiting protrusion extending into the limiting groove to limit the lower rotating shaft from rotating relative to the movable hole.

[0006] The grilling machine provided in the present application limits the rotation of the lower rotating shaft relative to the movable hole by the cooperation of the limiting protrusion and the limiting groove, thereby limiting the relative rotation of the hinge assembly and the base assembly, thereby improving the connection strength between the hinge assembly and the base assembly, thereby stabilizing the upper cover assembly in an upright state and reducing the possibility of the upper cover assembly tipping over.

[0007] In one of the embodiments, the limiting protrusion extends from the outer surface of the lower rotating shaft along the length direction of the hinge assembly, and the limiting groove extends downward from the bottom wall of the movable hole.

[0008] In this way, the lower rotating shaft can move downward to make the limiting protrusion extend into the limiting groove, and the lower rotating shaft can move upward to make the limiting protrusion escape from the limiting groove, so that the opening and closing operations of the grilling machine are very convenient.

[0009] In one of the embodiments, along the length direction of the hinge assembly, the minimum length L1 of the limiting protrusion protruding relative to the outer surface of the lower shaft is 3 mm to 5 mm.

[0010] In this way, it is ensured that the limiting protrusion and the limiting groove have sufficient matching length, thereby ensuring that the limiting groove effectively stops the limiting protrusion, thereby ensuring that the hinge assembly will not rotate relative to the base assembly, and further ensuring the stability of the grill in the first open cover state.

[0011] In one of the embodiments, the minimum depth L2 of the limiting groove is 3.2 mm to 5.2 mm.

[0012] In this way, it is ensured that the part of the limiting protrusion protruding from the lower shaft can be fully extended into the limiting groove, thereby avoiding that the length of the limiting protrusion cannot be effectively utilized, and ensuring that the limiting protrusion and the limiting groove have sufficient matching length, so that the limiting groove can effectively stop and limit the limiting protrusion.

[0013] In one embodiment, the lower rotating shaft has a circular shape, and the limiting protrusion has a first side surface and a second side surface connected to the outer surface of the lower rotating shaft and arranged opposite to each other, the first side surface is approximately tangent to the outer surface of the lower rotating shaft, and the second side surface intersects the outer surface of the lower rotating shaft approximately perpendicularly.

[0014] In this way, the plane where the second side surface is located passes through the rotation center of the lower rotating shaft, so that the rotation of the lower rotating shaft can be better limited by the abutment between the second side surface and the inner wall of the limiting groove. At the same time, since the first side surface is roughly tangent to the outer surface of the lower rotating shaft, the thickness of the limiting protrusion is larger, so that its structural strength is higher, thereby further improving the connection strength between the hinge assembly and the base assembly, which is beneficial to the stability of the upper cover assembly in the upright state.

[0015] In one of the embodiments, the limiting groove is arranged on a side of the lower end of the movable hole away from the center of the base assembly.

[0016] In this way, the side wall of the limiting groove away from the center of the base assembly can block the limiting protrusion, thereby preventing the hinge assembly from rotating in a direction away from the center of the base assembly, thereby ensuring the stability of the hinge assembly in an upright state.

[0017] In one embodiment, the side wall of the movable hole is provided with an avoidance groove capable of accommodating the limiting protrusion, and when the lower rotating shaft moves to the upper end of the movable hole, the limiting protrusion can be rotated into the avoidance groove so that the lower rotating shaft can rotate in the movable hole.

[0018] In this way, the upper cover assembly is lifted up, so that when the lower rotating shaft moves to the upper end of the movable hole, the upper cover assembly can be rotated in a further opening direction, so that the upper cover assembly can be rotated to the second opening state. It can be seen that the avoidance groove can realize the normal opening of the grilling machine.

[0019] In one embodiment, the avoidance groove is disposed on a side of the movable hole close to the center of the base component and extends toward the center of the base component.

[0020] In this way, the position of the avoidance groove is adapted to the position of the limiting protrusion, so that when the grilling machine is in the second cover-opening state, the limiting protrusion is just received in the avoidance groove.

[0021] In one of the embodiments, the base assembly is provided with a lower hinge groove, the hinge assembly is movably disposed in the lower hinge groove up and down, and the movable hole is disposed on the side wall of the lower hinge groove.

[0022] With this arrangement, the structure is very compact.

[0023] In one embodiment, the base assembly includes a lower shell and a lower baking tray, the lower shell is provided with a first groove, the side wall of the first groove is provided with a first hole opening upward, the lower baking tray is provided with a second groove, the side wall of the second groove is provided with a second hole opening downward, the lower baking tray is fixedly connected to the lower shell, the first groove and the second groove cooperate to form the lower hinge groove, and the first hole and the second hole cooperate to form the movable hole.

[0024] In this way, the first groove provided in the lower shell and the second groove provided in the lower baking tray are combined into a lower hinge groove, and the first hole provided in the lower shell and the second hole provided in the lower baking tray are combined into a movable hole, so that the hinge assembly is easily installed.

[0049] See also Figures 1 to 4 The present application provides a grilling machine, comprising: a base assembly 10, an upper cover assembly 20 and a hinge assembly 30, wherein the upper cover assembly 20 is rotatably connected to the base assembly 10 via the hinge assembly 30. For details, see Figures 5 to 8 One end of the hinge assembly 30 is rotatably connected to the base assembly 10 through the lower rotating shaft 60 , and the other end is rotatably connected to the upper cover assembly 20 through the upper rotating shaft 40 .

[0050] The grilling machine has a closed state, a first open state in which the upper cover assembly 20 stands upright relative to the base assembly 10, and a second open state in which the upper cover assembly 20 is flipped to one side of the base assembly 10. Figure 1 As shown, in the closed state, the upper cover assembly 20 covers the base assembly 10, and the angle between the upper cover assembly 20 and the base assembly 10 is approximately 0°. Figure 3 As shown, in the first open state, the angle θ between the upper cover assembly 20 and the base assembly 10 is close to 90°. In some embodiments, the angle θ between the upper cover assembly 20 and the base assembly 10 can be 90° to 110°, for example, θ is 90°, 93°, 95°, 98°, or 110°, etc. Figure 3 As shown, preferably θ>90° to avoid accidental touch causing the upper cover assembly 20 to close. Figure 4 As shown, in the second open cover state, the angle between the upper cover assembly 20 and the base assembly 10 is approximately 180°.

[0051] See also Figure 5 and Figure 6 The upper cover assembly 20 includes an upper shell 21 and an upper baking pan 22 mounted on the upper shell 21, and the base assembly 10 includes a lower shell 11 and a lower baking pan 12 mounted on the lower shell 11. In the closed state, the upper baking pan 22 cooperates with the lower baking pan 12 to form a relatively closed cooking cavity. Figure 2 As shown, the hinge assembly 30 can also be raised and lowered relative to the base assembly 10, so that the upper cover assembly 20 has a floating function, so that when the cover is closed, the food can lift up the upper cover assembly 20, and at this time, there is a certain distance between the upper baking tray 22 and the lower baking tray 12, so as to prevent the food from being squeezed too firmly. Figure 7As shown, the base assembly 10 is provided with a lower hinge groove 13, and the hinge assembly 30 is movably arranged in the lower hinge groove 13. When the hinge assembly 30 moves downward to the bottom of the lower hinge groove 13, the lower hinge groove 13 restricts the hinge assembly 30 in an upright state. At this time, the hinge assembly 30 cannot rotate relative to the base assembly 10 around the lower rotating shaft 60, while the upper cover assembly 20 can rotate relative to the hinge assembly 30 around the upper rotating shaft 40, so that the grilling machine can be switched between the closed cover state and the first open cover state; when the hinge assembly 30 moves upward to the notch at the upper end of the lower hinge groove 13, the hinge assembly 30 can rotate around the lower rotating shaft 60, so that the hinge assembly 30 can be rotated from the upright state to the horizontal state, and accordingly, the grilling machine can be switched from the first open cover state to the second open cover state.

[0052] In order to ensure the smooth up and down movement of the hinge assembly, a certain clearance is usually reserved between the inner wall of the lower hinge groove and the hinge assembly, so that the hinge assembly has a small swing space in the lower hinge groove. As a result, when the grill is in the first open state, the connection strength between the hinge assembly and the base assembly is weak, and the upper cover assembly is prone to tipping over.

[0053] In this application, please see Figure 7 , Figure 8 and Figures 10 to 15 The hinge assembly 30 is fixed with a lower rotating shaft 60, and the base assembly 10 is provided with a movable hole 14. The lower rotating shaft 60 is inserted into the movable hole 14, and the lower rotating shaft 60 can move up and down in the movable hole 14. The lower rotating shaft 60 is provided with a limiting protrusion 51, and the lower end of the movable hole 14 is provided with a limiting groove 52. When the grilling machine is in the first open cover state, the lower rotating shaft 60 is located at the lower end of the movable hole 14, and the limiting protrusion 51 extends into the limiting groove 52 to limit the rotation of the lower rotating shaft 60 relative to the movable hole 14. In this way, the limiting protrusion 51 and the limiting groove 52 cooperate to limit the rotation of the lower rotating shaft 60 relative to the movable hole 14, which also limits the relative rotation of the hinge assembly 30 and the base assembly 10, and improves the connection strength between the hinge assembly 30 and the base assembly 10, so that the upper cover assembly 20 can be stabilized in the upright state, and the upper cover assembly 20 can be reduced from tipping over.

[0054] For further information, see Figures 8 to 15, the limiting protrusion 51 extends from the outer surface of the lower rotating shaft 60 along the length direction of the hinge assembly 30, and the limiting groove 52 extends downward from the bottom wall of the movable hole 14. In this way, the lower rotating shaft 60 moves downward to make the limiting protrusion 51 extend into the limiting groove 52, and the lower rotating shaft 60 moves upward to make the limiting protrusion 51 escape from the limiting groove 52, so that the lower rotating shaft 60 can rotate in the movable hole 14. It can be seen that when the grilling machine is in the first cover-opening state, the lower rotating shaft 60 moves downward to the lower end of the movable hole 14, and the limiting protrusion 51 extends into the limiting groove 52, so that the upper cover assembly 20 remains in the first cover-opening state. When the grilling machine needs to be further opened, it is only necessary to lift the upper cover assembly 20 upward, so that the hinge assembly 30 and the lower rotating shaft 60 move upward together, and the limiting protrusion 51 escapes from the limiting groove 52, so that the upper cover assembly 20 can be rotated and flipped to the second cover-opening state, which is very convenient to operate.

[0055] For further information, see Fig. 9 , along the length direction of the hinge assembly 30, the minimum length L1 of the limiting protrusion 51 protruding relative to the outer surface of the lower rotating shaft 60 is 3mm to 5mm. In this way, it is ensured that the limiting protrusion 51 and the limiting groove 52 have a sufficient matching length, so as to ensure that the limiting groove 52 effectively stops the limiting protrusion 51, thereby ensuring that the hinge assembly 30 will not rotate relative to the base assembly 10, and further ensuring the stability of the grilling machine when it is in the first open cover state. In some specific embodiments, L1 can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, or any other value within the range of 3mm to 5mm.

[0056] For further information, see Fig.11 , considering the error problem in the actual processing process, the minimum depth L2 of the limiting groove 52 is 3.2mm~5.2mm. In this way, it is ensured that the part of the limiting protrusion 51 protruding from the lower shaft 60 can be fully extended into the limiting groove 52, so as to avoid that the length of the limiting protrusion 51 cannot be effectively utilized, to ensure that the limiting protrusion 51 and the limiting groove 52 have sufficient matching length, so that the limiting groove 52 effectively stops the limiting protrusion 51. In some specific embodiments, L2 can be 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, 5.2mm or any other value within the range of 3.2mm~5.2mm.

[0057] See also Figure 8 and Fig. 9In this embodiment, the lower rotating shaft 60 has a circular shape, and the limiting protrusion 51 has a first side surface 511 and a second side surface 512 connected to the outer surface of the lower rotating shaft 60 and arranged opposite to each other. The first side surface 511 is substantially tangent to the outer surface of the lower rotating shaft 60, and the second side surface 512 is substantially perpendicular to the outer surface of the lower rotating shaft 60. It can be understood that the "substantially tangent" and "substantially perpendicular to" in "the first side surface 511 is substantially tangent to the outer surface of the lower rotating shaft 60, and the second side surface 512 is substantially perpendicular to the outer surface of the lower rotating shaft 60" can be understood as "tangent" and "perpendicularly intersecting" within the normal process error or measurement error range. In other words, the limiting protrusion 51 of this embodiment is connected to the lower 1 / 4 circle of the left side (left side of the figure) of the outer surface of the lower rotating shaft 60. In this way, the plane where the second side surface 512 is located passes through the rotation center of the lower rotating shaft 60, so that the second side surface 512 and the inner side wall of the limiting groove 52 can better limit the rotation of the lower rotating shaft 60. At the same time, since the first side surface 511 is roughly tangent to the outer surface of the lower rotating shaft 60, the limiting protrusion 51 has a larger thickness, so that its structural strength is higher, thereby further improving the connection strength between the hinge assembly 30 and the base assembly 10, which is conducive to the upper cover assembly being stable in the upright state. However, it is not limited to this. In other embodiments, the limiting protrusion 51 can also be set at other positions on the outer surface of the lower rotating shaft 60, for example, the limiting protrusion 51 can be set at a position centered on the lower surface.

[0058] In this embodiment, the limiting protrusion 51 is integrally formed on the outer surface of the lower rotating shaft 60, which has a simple structure and high structural strength. However, it is not limited to this. In other embodiments, the limiting protrusion 51 and the lower rotating shaft 60 can also be a split structure, and the limiting protrusion 51 can be fixed to the lower rotating shaft 60 by bonding, welding or fastener connection, and this application does not limit this.

[0059] See also Figures 10 to 13 Furthermore, the limiting groove 52 is arranged at the side of the lower end of the movable hole 14 away from the center of the base assembly 10. Accordingly, when the grilling machine is in the first open cover state, the limiting protrusion 51 is located below the lower rotating shaft 60 and away from the center of the base assembly 10. In this way, the limiting groove 52 is away from the center of the base assembly 10 (i.e. Fig.13 The side wall of the hinge assembly 30 (the left side in the figure) can block the limiting protrusion 51, thereby preventing the hinge assembly 30 from rotating in a direction away from the center of the base assembly 10, thereby ensuring the stability of the hinge assembly 30 in the upright state. It can be understood that the "center of the base assembly 10" herein refers to the central area of ​​the base assembly 10, which is only used as a reference system to define the positional relationship of related elements, and does not define whether the base assembly 10 is a regular or symmetrical structure.

[0060] See also Figures 10 to 15Furthermore, the side wall of the movable hole 14 is provided with an avoidance groove 142 capable of accommodating the limiting protrusion 51. When the lower rotating shaft 60 moves to the upper end of the movable hole 14, the limiting protrusion 51 can be rotated into the avoidance groove 142, so that the lower rotating shaft 60 can rotate in the movable hole 14. In this way, the upper cover assembly 20 is lifted upward, so that when the lower rotating shaft 60 moves to the upper end of the movable hole 14, the upper cover assembly 20 can be rotated in the direction of further opening the cover, so that the upper cover assembly 20 can be rotated to the second open cover state. It can be seen that the avoidance groove 142 can realize the normal opening of the grilling machine.

[0061] Furthermore, the avoidance groove 142 is disposed on one side of the movable hole 14 close to the center of the base assembly 10, and extends toward the center of the base assembly 10. Thus, the position of the avoidance groove 142 is adapted to the position of the limiting protrusion 51, so that when the grill is in the second open cover state, the limiting protrusion 51 is just received in the avoidance groove 142.

[0062] See also Figure 7 In this embodiment, the movable hole 14 is arranged on the side wall of the lower hinge groove 13, and the structure is very compact. When the hinge assembly 30 moves up and down in the lower hinge groove 13, the lower rotating shaft 60 moves up and down in the movable hole 14. When the hinge assembly 30 moves to the bottom of the lower hinge groove 13, the lower rotating shaft 60 is located at the lower end of the movable hole 14, and the limiting protrusion 51 extends into the limiting groove 52. At this time, the hinge assembly 30 cannot rotate relative to the base assembly 10; when the hinge assembly 30 moves to the upper end of the lower hinge groove 13, the lower rotating shaft 60 is located at the upper end of the movable hole 14, and the limiting protrusion 51 escapes from the limiting groove 52. At this time, the hinge assembly 30 can rotate relative to the base assembly 10 in a direction away from the center of the base assembly 10.

[0063] See also Figure 7 , Fig.16 and Fig.17In one embodiment, the lower shell 11 is provided with a first groove 111, the side wall of the first groove 111 is provided with a first hole 112 with an opening facing upward, the lower baking tray 12 is provided with a second groove 121, the side wall of the second groove 121 is provided with a second hole 122 with an opening facing downward, the lower baking tray 12 is fixedly connected to the lower shell 11, the first groove 111 and the second groove 121 cooperate to form a lower hinge groove 13, and the first hole 112 and the second hole 122 cooperate to form a movable hole 14. In this way, when assembling, the hinge assembly 30 can be placed in the first groove 111 first, and the lower rotating shaft 60 can be placed in the first hole 112, and then the lower baking tray 12 can be placed on the lower shell 11, and the opening of the first groove 111 is aligned with the opening of the second groove 121, and the opening of the first hole 112 is aligned with the opening of the second hole 122, and then the lower baking tray 12 and the lower shell 11 are connected, and the hinge assembly 30 can be installed on the base assembly 10. The lower baking tray 12 and the lower shell 11 can be connected by screws, and installation and disassembly are very convenient. In this embodiment, the first groove 111 provided on the lower shell 11 and the second groove 121 provided on the lower baking tray 12 are combined into the lower hinge groove 13, and the first hole 112 provided on the lower shell 11 and the second hole 122 provided on the lower baking tray 12 are combined into the movable hole 14, so that the hinge assembly 30 can be easily installed. However, it is not limited thereto. In other embodiments, the lower hinge groove 13 and the movable hole 14 can also be formed separately on the lower shell 11, and the lower shell 11 can also be provided with a split structure, as long as the hinge assembly 30 and the lower rotating shaft 60 can be respectively installed in the lower hinge groove 13 and the movable hole 14.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
