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, and the hinge assembly can be lifted and lowered relative to the base assembly. The grilling machine has a first open cover state in which the upper cover assembly stands upright relative to the base assembly, and a limit assembly is provided between the base assembly and the hinge assembly, wherein the limit assembly comprises a limit protrusion and a limit groove, wherein one of the limit protrusion and the limit groove is provided on the hinge assembly, and the other is provided on the base assembly, and when the grilling machine is in the first open cover state, the limit protrusion abuts against an inner wall of the limit groove to limit the hinge assembly from rotating relative to the base assembly.

[0006] The grilling machine provided in the present application is provided with a limit assembly, and the limit assembly includes a limit protrusion and a limit groove. The limit protrusion and the limit groove cooperate to limit the relative rotation of the hinge assembly and the base assembly, thereby improving the connection strength between the hinge assembly and the base assembly, so that the upper cover assembly can be stabilized in an upright state and the upper cover assembly can be reduced from tipping over.

[0007] In one embodiment, the base assembly is provided with a lower hinge groove, the hinge assembly can be movably arranged in the lower hinge groove up and down, the limiting groove is provided on the bottom wall of the lower hinge groove, and the limiting protrusion is convexly provided on the end of the hinge assembly located in the limiting groove.

[0008] In this way, the hinge assembly can move downward to allow the limiting protrusion to extend into the limiting groove, and the hinge assembly can move upward to allow the limiting protrusion to 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, the limiting groove is located on a side of the lower hinge groove away from the center of the base assembly.

[0010] Correspondingly, when the grilling machine is in the first open-lid state, the limiting protrusion is located on the side of the lower end of the hinge assembly away from the center of the base assembly. In this way, the limiting protrusion is located on the side of the lower rotating shaft away from the center of the base assembly, and the side wall of the limiting protrusion can be more tightly abutted against the side wall of the limiting groove on the side close to the center of the base assembly, thereby better 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 the upright state.

[0011] In one embodiment, the limiting protrusion is provided with a supporting surface, and the side wall of the limiting groove is provided with a stop surface. When the grilling machine is in the first open cover state, the hinge assembly is in an upright state, and the supporting surface is against the stop surface.

[0012] In this way, the rotation of the hinge assembly can be effectively limited by the cooperation between the abutting surface and the stop surface.

[0013] In one of the embodiments, the abutment surface is inclined upward when the hinge assembly is in an upright state.

[0014] In this way, in the first open cover state, the force between the abutting surface and the stop surface is greater, and the limiting protrusion can be buckled more tightly with the limiting groove, so that the connection strength between the hinge assembly and the base assembly is higher, which is more conducive to maintaining the upper cover assembly in an upright state.

[0015] In one of the embodiments, when the hinge assembly is in an upright state, an angle α between the abutting surface and a horizontal plane is 82° to 87°.

[0016] In this way, it can be ensured that the limiting protrusion can be easily inserted into and easily removed from the limiting groove, and the limiting protrusion is tightly buckled after being inserted into the limiting groove, so that the connection strength between the hinge assembly and the base assembly is higher.

[0017] In one embodiment, the hinge assembly is rotatably connected to the base assembly via a lower rotating shaft. When the hinge assembly moves to the upper end of the lower hinge groove, the hinge assembly can rotate around the axis of the lower rotating shaft. The vertical plane passing through the axis of the lower rotating shaft when the hinge assembly is in an upright state is defined as the center plane of the rotating shaft. The minimum distance D1 between the center plane of the rotating shaft and the abutment surface is 0 to 2 mm.

[0018] The greater the minimum distance between the abutment surface and the center plane of the shaft, the easier it is for the hinge assembly to rotate around the lower shaft, and thus the easier it is for the upper cover assembly to tip over. In this embodiment, the minimum distance D1 between the center plane of the shaft and the abutment surface is 0-2 mm, and the hinge assembly is not easy to rotate around the lower shaft, so that the hinge assembly can be stabilized in an upright state, providing effective support for the upper cover assembly and preventing the upper cover assembly from tipping over.

[0019] In one of the embodiments, the side wall on the side close to the center of the base assembly when the hinge assembly is in an upright state is defined as a first side wall, and the side wall on the side away from the center of the base assembly when the hinge assembly is in an upright state is defined as a second side wall; the abutment surface is located on the side of the center plane of the rotating shaft close to the second side wall; or the abutment surface is located on the side of the center plane of the rotating shaft close to the first side wall; or a part of the abutment surface is located on the side of the center plane of the rotating shaft close to the first side wall, and the other part is located on the side of the center plane of the rotating shaft close to the second side wall; or the abutment surface coincides with the center plane of the rotating shaft.

[0020] In one of the embodiments, the minimum thickness of the limiting protrusion is D, and D≥4 mm.

[0021] In this way, it is ensured that the limiting protrusion has sufficient structural strength to prevent the limiting protrusion from being broken due to the force of the limiting protrusion abutting against the stop surface.

[0022] In one of the embodiments, the length L of the limiting protrusion protruding relative to the end of the hinge assembly is 3 mm to 10 mm.

[0023] 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.

[0024] In one of the embodiments, the side wall of the lower hinge groove is provided with an avoidance groove for accommodating the limiting protrusion. When the hinge assembly moves to the upper end of the lower hinge groove, the limiting protrusion can be rotated into the avoidance groove so that the hinge assembly can rotate at the upper end of the lower hinge groove. The grilling machine also has a second open cover state in which the upper cover assembly is flipped open to one side of the base assembly. When the grilling machine is in the second open cover state, the hinge assembly is in a flat state, and the limiting protrusion is accommodated in the avoidance groove.

[0025] In this way, the upper cover assembly is lifted up, so that when the hinge assembly moves to the upper end of the lower hinge groove, the limiting protrusion is separated from the limiting groove, and the upper cover assembly can be rotated in the direction of further opening the cover, 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 grill. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] 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. 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 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. The hinge assembly 30 has an upright state and a horizontal state. When the grilling machine is in the closed state and the first open state, the hinge assembly 30 is in the upright state. Figure 7 When the grill is in the second open state, the hinge assembly 30 is in a flat state, such as Fig. 9 When the grilling machine switches between the closed state and the first open state, the hinge assembly 30 remains in the upright state, and the upper cover assembly 20 rotates around the upper rotation axis 40; when the grilling machine switches between the first open state and the second open state, the hinge assembly 30 and the upper cover assembly 20 rotate together around the lower rotation axis 60. In this way, there is only one rotation in the process of opening and closing the grilling machine between the closed state and the first open state, and between the first open state and the second open state, so that the opening and closing process is very smooth.

[0052] 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. Fig.11 As shown, the base assembly 10 is provided with a lower hinge groove 13, and the side wall of the lower hinge groove 13 is provided with a movable hole 14 extending along the height direction of the base assembly 10. The hinge assembly 30 can be movably arranged in the lower hinge groove 13 up and down, and the lower rotating shaft 60 is passed through the movable hole 14, so that 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 downward 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 lower hinge groove 13 restricts the hinge assembly 30 in the upright state. At this time, the hinge assembly 30 cannot rotate around the lower rotating shaft 60 relative to the base assembly 10, while the upper cover assembly 20 can rotate around the upper rotating shaft 40 relative to the hinge assembly 30, 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 lower rotating shaft 60 is located at the upper end of the movable hole 14, and 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.

[0053] 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.

[0054] In this application, please see Figure 8 , Fig.12 , Fig.13 and Fig.15 A limiting assembly 50 is provided between the base assembly 10 and the hinge assembly 30. The limiting assembly 50 includes a limiting protrusion 51 and a limiting groove 52. One of the limiting protrusion 51 and the limiting groove 52 is provided on the hinge assembly 30, and the other is provided on the base assembly 10. When the grilling machine is in the first open cover state, the limiting protrusion 51 extends into the limiting groove 52, and the limiting protrusion 51 abuts against the inner wall of the limiting groove 52 to limit the rotation of the hinge assembly 30 relative to the base assembly 10. In this way, by providing the limiting assembly 50, and the limiting assembly 50 includes the limiting protrusion 51 and the limiting groove 52, the limiting protrusion 51 and the limiting groove 52 cooperate to limit the relative rotation of the hinge assembly 30 and the base assembly 10, thereby improving 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.

[0055] In this embodiment, the limiting protrusion 51 is provided on the hinge assembly 30, and the limiting groove 52 is provided on the base assembly 10, which has a simple structure and is easy to process. Of course, in other embodiments, the limiting protrusion may be provided on the base assembly, and the limiting groove may be provided on the hinge assembly.

[0056] Furthermore, the limiting groove 52 is provided on the bottom wall of the lower hinge groove 13, and the limiting protrusion 51 is provided on the end of the hinge assembly 30 located in the limiting groove 52. In this way, the limiting protrusion 51 can be extended into the limiting groove 52 when the hinge assembly 30 moves downward, and the limiting protrusion 51 can be disengaged from the limiting groove 52 when the hinge assembly 30 moves upward, so that when the hinge assembly 30 moves to the upper end of the lower hinge groove 13, it can rotate relative to the base assembly 10. It can be seen that when the grilling machine is in the first open cover state, the hinge assembly 30 moves downward to the bottom of the lower hinge groove 13, and the limiting protrusion 51 is extended into the limiting groove 52, so that the upper cover assembly 20 is kept in the first open cover state. When the grilling machine needs to be further opened, the upper cover assembly 20 only needs to be lifted upwards to move the hinge assembly 30 upwards and allow the limiting protrusion 51 to escape from the limiting groove 52. When the hinge assembly 30 moves to the upper end of the lower hinge groove 13, the upper cover assembly 20 can be rotated and flipped over to the second open cover state, which is very convenient to operate.

[0057] For further information, see Figure 7 and Figure 8 , the limiting groove 52 is located on the side of the lower hinge groove 13 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 on the side of the lower end of the hinge assembly 30 away from the center of the base assembly 10. In this way, the limiting protrusion 51 is located on the side of the lower rotating shaft 60 away from the center of the base assembly 10, and the side wall of the limiting protrusion 51 (i.e., the abutting surface 511 described below) can be more tightly abutted against the side wall of the limiting groove 52 on the side close to the center of the base assembly 10 (i.e., the stop surface 521 described below), thereby better preventing the hinge assembly 30 from rotating in the direction away from the center of the base assembly 10, and 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 components, and does not define whether the base assembly 10 is a regular or symmetrical structure.

[0058] See also Figure 8 , Fig.12 , Fig.13 and Fig.15 The limiting protrusion 51 is provided with a supporting surface 511, and the side wall of the limiting groove 52 is provided with a stopping surface 521. When the grilling machine is in the first open cover state, the hinge assembly 30 is in an upright state, and the supporting surface 511 is against the stopping surface 521. In this way, the rotation of the hinge assembly 30 can be effectively limited by the cooperation between the supporting surface 511 and the stopping surface 521.

[0059] In one embodiment, the abutment surface 511 is tilted upward when the hinge assembly 30 is in the upright state. It is understandable that since the hinge assembly 30 can rotate relative to the base assembly 10, the direction of the abutment surface 511 will change in different states. Here, the direction of the abutment surface 511 when the hinge assembly 30 is in the upright state is defined. Fig.17 As shown, for a physical structure, the inclined surface M is an upwardly inclined surface, and the inclined surface N is a downwardly inclined surface. The abutting surface 511 in the present application is the same as the inclined surface M, and is an upwardly inclined surface. In this embodiment, since the abutting surface 511 is inclined upwardly when the hinge assembly 30 is in the upright state, the abutting force between the abutting surface 511 and the stop surface 521 is greater in the first open cover state, and the limiting protrusion 51 can be more tightly fastened with the limiting groove 52, so that the connection strength between the hinge assembly 30 and the base assembly 10 is higher, which is more conducive to maintaining the upper cover assembly 20 in the upright state. Of course, in other embodiments, the abutting surface 511 can also be extended in the vertical direction when the hinge assembly 30 is in the upright state.

[0060] It is understandable that the inclination angle of the stop surface 521 is consistent with the inclination angle of the abutment surface 511 , thus ensuring a larger contact area between the abutment surface 511 and the stop surface 521 , thereby ensuring reliable fit between the hinge assembly 30 and the base assembly 10 .

[0061] For further information, see Fig.13 As shown, when the hinge assembly 30 is in the upright state, the angle α between the abutting surface 511 and the horizontal plane is 82° to 87°. In this way, it can be ensured that the limiting protrusion 51 is easy to extend into and easy to escape from the limiting groove 52, and the limiting protrusion 51 is tightly fastened after extending into the limiting groove 52, so that the connection strength between the hinge assembly 30 and the base assembly 10 is high. In some specific embodiments, α can be 82°, 83°, 84°, 85°, 86°, 87°, or any other value within the range of 82° to 87°.

[0062] The hinge assembly 30 is rotatably connected to the base assembly 10 via the lower rotating shaft 60. When the hinge assembly 30 moves to the upper end of the lower hinge groove 13, the hinge assembly 30 can rotate around the axis of the lower rotating shaft 60. Fig.13 , the vertical plane passing through the axis line of the lower rotating shaft 60 when the hinge assembly 30 is in the upright state is defined as the center plane of the rotating shaft, and the minimum distance D1 between the center plane of the rotating shaft and the abutment surface 511 is 0 to 2 mm. The greater the minimum distance between the abutment surface 511 and the center plane of the rotating shaft, the easier it is for the hinge assembly 30 to rotate around the lower rotating shaft 60, and thus the easier it is for the upper cover assembly 20 to tip over. In this embodiment, the minimum distance D1 between the center plane of the rotating shaft and the abutment surface 511 is 0 to 2 mm, and the hinge assembly 30 is not easy to rotate around the lower rotating shaft 60, so that the hinge assembly 30 can be stabilized in the upright state, providing effective support for the upper cover assembly 20 and preventing the upper cover assembly 20 from tipping over. In some specific embodiments, D1 can be 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, or any other value in the range of 0 to 2mm.

[0063] Please combine Figure 8 As shown in FIG13 , the side wall of the hinge assembly 30 close to the center of the base assembly 10 when the hinge assembly 30 is in the upright state is defined as the first side wall 31, and the side wall of the hinge assembly 30 away from the center of the base assembly 10 when the hinge assembly 30 is in the upright state is defined as the second side wall 32. Fig.13 In one embodiment, the abutting surface 511 is located on the side of the central surface 610 of the rotating shaft close to the second side wall 32; but not limited thereto, see Fig.14In another embodiment, the abutting surface 511 is located on the side of the central plane 610 of the rotating shaft close to the first side wall 31; in another embodiment, a portion of the abutting surface 511 is located on the side of the central plane 610 of the rotating shaft close to the first side wall 31, and another portion is located on the side of the central plane 610 of the rotating shaft close to the second side wall 32, and preferably the center of the abutting surface 511 is located on the central plane 610 of the rotating shaft. In yet another embodiment, the abutting surface 511 coincides with the central plane 610 of the rotating shaft, in other words, the abutting surface 511 is a vertical surface extending in the vertical direction.

[0064] Furthermore, the minimum thickness of the limiting protrusion 51 is D, and D≥4 mm. In this way, the limiting protrusion 51 is ensured to have sufficient structural strength to prevent the limiting protrusion 51 from being broken due to the force of the limiting protrusion 51 abutting against the stop surface 521 .

[0065] Furthermore, the length L of the limiting protrusion 51 protruding relative to the end of the hinge assembly 30 is 3mm to 10mm. In this way, it is ensured that the limiting protrusion 51 and the limiting groove 52 have 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, thereby ensuring the stability of the grilling machine in the first open cover state. In some specific embodiments, L can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or any other value within the range of 3mm to 10mm.

[0066] In this embodiment, the limiting protrusion 51 is integrally formed on the outer surface of the hinge assembly 30, and has a simple structure and high structural strength. However, it is not limited thereto, in other embodiments, the limiting protrusion 51 and the hinge assembly 30 may also be a split structure, and the limiting protrusion 51 may be fixed to the hinge assembly 30 by bonding, welding or fastener connection, and this application does not limit this.

[0067] For further information, see Figure 8 and Fig.10 The side wall of the lower hinge groove 13 is provided with an avoidance groove 132 for accommodating the limiting protrusion 51. When the hinge assembly 30 moves to the upper end of the lower hinge groove 13, the limiting protrusion 51 can be transferred into the avoidance groove 132, so that the hinge assembly 30 can rotate at the upper end of the lower hinge groove 13. When the grilling machine is in the second open cover state, the hinge assembly 30 is in a flat state, and the limiting protrusion 51 is accommodated in the avoidance groove 132. In this way, when the upper cover assembly 20 is lifted up, so that the hinge assembly 30 moves to the upper end of the lower hinge groove 13, the limiting protrusion 51 is separated from the limiting groove 52, and 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 132 can realize the normal opening of the grilling machine.

[0068] See also Fig. 9and Fig.10 Furthermore, the avoidance groove 132 is provided on one side of the lower hinge groove 13 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 132 is adapted to the position of the limiting protrusion 51, so that when the grilling machine is in the second open cover state, the limiting protrusion 51 is just received in the avoidance groove 132.

[0069] See also Figure 8 , Fig.10 and Fig.11 In one embodiment, the lower grilling pan 12 is fixedly connected to the lower shell 11, and the lower grilling pan 12 and the lower shell 11 cooperate to form a lower hinge groove 13 and an avoidance groove 132. When the grilling machine is in the second open cover state, the limiting protrusion 51 abuts against the lower grilling pan 12. In this way, it is easy to install the hinge assembly 30 in the lower hinge groove 13, and when the grilling machine is in the second open cover state, the lower grilling pan 12 can block the limiting protrusion 51, so that the hinge assembly 30 can be in a flat state. In the flat state, only the upper surface of the hinge assembly 30 is exposed to the outside, so that even if it is stained with oil smoke during use, it is very easy to clean.

[0070] See also Fig.11 , Fig.15 and Fig.16In 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 can be formed separately on the lower shell 11, for example, the lower shell 11 is provided as a split structure, as long as the hinge assembly 30 can be installed in the lower hinge groove 13. In addition, the avoidance groove 132 and the movable hole 14 can also be formed separately on the lower shell 11, and the lower shell 11 can also be provided as a split structure, as long as the hinge assembly 30 and the lower rotating shaft 60 can be installed in the lower hinge groove 13 and the movable hole 14 respectively.
