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 one end of the hinge assembly is rotatably connected to the base assembly via a lower rotating shaft, and the other end is rotatably connected to the upper cover assembly, the lower rotating shaft is fixedly connected to the hinge assembly, 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, a limit assembly is provided between the lower rotating shaft and the base assembly, and the limit assembly is used to limit the hinge assembly from rotating relative to the base assembly when the grilling machine is in the first open cover state.

[0006] The grilling machine provided in the present application has a limit assembly between the lower rotating shaft and the base assembly. The limit assembly limits 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 embodiment, the limit stop assembly includes a limit stop block provided on the lower rotating shaft and a limit stop rib provided on the base assembly, and when the grilling machine is in the first open cover state, the limit stop block abuts against one side of the limit stop rib.

[0008] In this way, the rotation of the lower shaft can be limited by the limit stopper abutting against the limit stop rib, thereby limiting the rotation of the hinge assembly. The limit assembly structure is very simple.

[0009] In one embodiment, the base assembly is provided with a lower hinge groove, and the side wall of the lower hinge groove is provided with a movable hole extending along the height direction. The hinge assembly can be movably arranged in the lower hinge groove up and down, and the lower rotating shaft is passed through the movable hole and can move up and down along the movable hole. When the lower rotating shaft moves downward to the lower end of the movable hole, the limit stop block abuts against the limit stop rib; when the lower rotating shaft moves upward to the upper end of the movable hole, the limit stop block disengages from the limit stop rib.

[0010] Thus, when the grilling machine is in the first open cover state, the lower hinge groove restricts the hinge assembly to the upright state, and the lower rotating shaft is just located at the lower end of the movable hole. At this time, the limit stopper cooperates with the limit stopper rib to prevent the hinge assembly from rotating, thereby keeping the upper cover assembly in the first open cover state. When the grilling machine needs to be closed or further opened, the upper cover assembly only needs to be lifted upward, so that the hinge assembly and the lower rotating shaft move upward together, and the limit stopper is separated from the limit stopper rib, and the upper cover assembly can be rotated, which is very convenient to operate.

[0011] In one of the embodiments, the limit stopper is arranged at an end of the lower rotating shaft away from the hinge assembly, and the limit stop rib is located at a side of the movable hole away from the lower hinge groove.

[0012] In this way, the structure is compact, and the setting of the limit blocking rib does not affect the movement of the hinge assembly in the lower hinge groove, and does not affect the movement of the lower rotating shaft in the movable hole.

[0013] 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.

[0014] 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.

[0015] In one embodiment, the limit stop block is provided with a first anti-rotation surface, and the limit stop rib is provided with a second anti-rotation surface. When the grilling machine is in the first open-lid state, the first anti-rotation surface abuts against the second anti-rotation surface.

[0016] In this way, the rotation of the limit stopper is limited by the cooperation between the surfaces, the contact area at the cooperation is large, and the anti-rotation effect is good.

[0017] In one embodiment, the first anti-rotation surface is a plane, and the second anti-rotation surface is a plane.

[0018] In this way, the limit stop block and the limit rib cooperate reliably, the anti-rotation effect is good, and the plane is easy to process.

[0019] In one of the embodiments, the limit stopper is arranged at one end of the lower rotating shaft away from the hinge assembly, the lower rotating shaft is provided with a through hole, the through hole passes through the limit stopper, and the limit stopper is semi-annular.

[0020] In this way, the through hole on the lower shaft can be used for the wire to pass through, so as to facilitate the electrical connection between the electronic components on the upper cover assembly and the electronic components on the base assembly. The limit stopper is arranged at the end of the lower shaft away from the hinge assembly, and the through hole also passes through the limit stopper, so that the setting of the limit stopper does not affect the installation of the wire, and the structure is compact.

[0021] In one embodiment, the limit stop rib includes a rotation-stopping portion and a reinforcing rib, the second rotation-stopping surface is arranged on the rotation-stopping portion, and the reinforcing rib connects the rotation-stopping portion and the side wall of the lower hinge groove.

[0022] In this way, the structural strength of the limit retaining rib can be enhanced, so that the anti-rotation and limiting effect of the limit retaining rib on the limit stop block is more reliable.

[0023] In one of the embodiments, along the axial direction of the lower rotating shaft, the matching length L2 between the limit stop block and the limit stop rib is 3 mm to 10 mm.

[0024] In this way, it can be ensured that there is sufficient contact length between the limit stop rib and the limit stop block, thereby ensuring the limit stop rib's anti-rotation limiting effect on the limit stop block; at the same time, the matching length between the limit stop block and the limit stop rib will not be too long to affect the layout of the internal structure of the base assembly.

[0025] In one embodiment, along the axial direction of the lower rotating shaft, the length L1 of the limit stopper is 3 mm to 12 mm.

[0026] In this way, it is ensured that there is sufficient matching length between the limit stopper and the limit rib, thereby ensuring the limit rib's anti-rotation and limiting effect on the limit stopper, while the limit stopper will not be too long to affect the layout of the internal structure of the base assembly.

[0027] In one of the embodiments, the base assembly includes a lower shell, the limiting retaining rib is integrally formed with the lower shell, and the limiting retaining rib is formed by extending upward from the inner bottom wall of the lower shell.

[0028] In this way, the limiting retaining rib is directly formed integrally with the lower shell, eliminating the step of connecting the limiting retaining rib to the lower shell, and the structure has high strength, which can effectively limit the rotation of the lower shaft and the hinge assembly.

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

[0053] See also Figures 1 to 6 The present application provides a grilling machine, comprising: a base assembly 10, an upper cover assembly 20 and a hinge assembly 30, wherein one end of the hinge assembly 30 is rotatably connected to the base assembly 10 through a lower rotating shaft 60, and the other end of the hinge assembly 30 is rotatably connected to the upper cover assembly 20 through an upper rotating shaft 40.

[0054] See also Figures 1 to 4 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 bottom assembly is approximately 180°.

[0055] See also Figure 5 and Figure 6The 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 7 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 around the lower rotating shaft 60 relative to the base assembly 10, and 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 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.

[0056] 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.

[0057] In this application, please see Figures 8 to 12 As shown, the lower rotating shaft 60 is fixedly connected to the hinge assembly 30, and a limit assembly 50 is provided between the lower rotating shaft 60 and the base assembly 10. The limit assembly 50 is used to limit the rotation of the hinge assembly 30 relative to the base assembly 10 when the grilling machine is in the first open cover state. In this way, the relative rotation of the hinge assembly 30 and the base assembly 10 is limited by setting the limit assembly 50, and the connection strength between the hinge assembly 30 and the base assembly 10 is improved, so that the upper cover assembly 20 can be stabilized in the upright state, and the upper cover assembly 20 is reduced from tipping over.

[0058] For further information, see Figures 12 to 15The limit assembly 50 includes a limit stopper 51 provided on the lower rotating shaft 60 and a limit stopper 52 provided on the base assembly 10. When the grilling machine is in the first open cover state, the limit stopper 51 abuts against one side of the limit stopper 52. In this way, the lower rotating shaft 60 can be limited from rotating by the limit stopper 51 abutting against the limit stopper 52, thereby limiting the rotation of the hinge assembly 30. The limit assembly 50 has a very simple structure.

[0059] For further information, see Figure 7 , Fig. 9 and Fig.11 The side wall of the lower hinge groove 13 is provided with an active hole 14 extending in the height direction, and the lower rotating shaft 60 is passed through the active hole 14 and can move up and down along the active 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 active hole 14. When the lower rotating shaft 60 moves downward to the lower end of the active hole 14, the limit stopper 51 abuts against the limit stop rib 52, as shown in FIG. Fig. 9 When the lower shaft 60 moves upward to the upper end of the movable hole 14, the limit stopper 51 is disengaged from the limit stop rib 52, as Fig.11 As shown. In this way, when the grilling machine is in the first open cover state, the lower rotating shaft 60 is just located at the lower end of the movable hole 14. At this time, the limit stopper 51 cooperates with the limit stopper 52 to prevent the hinge assembly 30 from rotating, so that the upper cover assembly 20 remains in the first open cover state. When the grilling machine needs to be closed or further opened, the upper cover assembly 20 only needs to be lifted up, so that the hinge assembly 30 and the lower rotating shaft 60 move upward together, and the limit stopper 51 is separated from the limit stopper 52, and the upper cover assembly 20 can be rotated, which is very convenient to operate.

[0060] For further information, see Figures 12 to 15 The limit stopper 51 is arranged at one end of the lower rotating shaft 60 away from the hinge assembly 30, and the limit stopper 52 is arranged at one side of the movable hole 14 away from the lower hinge groove 13. In this way, the structure is compact, and the setting of the limit stopper 52 does not affect the movement of the hinge assembly 30 in the lower hinge groove 13, and does not affect the movement of the lower rotating shaft 60 in the movable hole 14.

[0061] For further information, see Figure 6 , Figure 7 and Fig.16The base assembly 10 includes a lower shell 11 and a lower baking tray 12. 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. The first hole 112 and the second hole 122 cooperate to form a movable hole 14. In this way, during assembly, the hinge assembly 30 can be placed in the first groove 111, and the lower rotating shaft 60 can be placed in the first hole 112. 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. 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 grill plate 12 and the lower shell 11 can be connected by screws, and installation and removal are very convenient. In this embodiment, the first groove 111 provided in the lower shell 11 and the second groove 121 provided in the lower grill plate 12 are combined into the lower hinge groove 13, and the first hole 112 provided in the lower shell 11 and the second hole 122 provided in the lower grill plate 12 are combined into the movable hole 14, so that the hinge assembly 30 can be easily installed. However, it is not limited to this. 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 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.

[0062] For further information, see Fig.15 The limiting retaining rib 52 is integrally formed with the lower shell 11, and the limiting retaining rib 52 extends upward from the inner bottom wall of the lower shell 11. In this way, the limiting retaining rib 52 is directly integrally formed with the lower shell 11, eliminating the step of connecting the limiting retaining rib 52 to the lower shell 11, and the structural strength is high, which can effectively limit the rotation of the lower shaft 60 and the hinge assembly 30.

[0063] For further information, see Figures 12 to 15 The limit stopper 51 is provided with a first anti-rotation surface 511, and the limit stop rib 52 is provided with a second anti-rotation surface 5211. When the grilling machine is in the first open cover state, the first anti-rotation surface 511 abuts against the second anti-rotation surface 5211. In this way, the limit stopper 51 is limited to rotate by the cooperation of the surfaces, the contact area at the cooperation is large, and the anti-rotation effect is good.

[0064] Furthermore, the first anti-rotation surface 511 is a plane, and the second anti-rotation surface 5211 is a plane, so that the limit stopper 51 and the limit stopper 52 cooperate reliably, the anti-rotation effect is good, and the plane is easy to process. Further, the lower rotating shaft 60 is provided with a through hole 61, and the through hole 61 passes through the limit stopper 51, and the limit stopper 51 is semi-annular. In this way, the through hole 61 on the lower rotating shaft 60 can allow the wire to pass through, so as to facilitate the electrical connection between the electronic components on the upper cover assembly 20 and the electronic components on the base assembly 10, and the through hole 61 also passes through the limit stopper 51, so that the setting of the limit stopper 51 does not affect the installation of the wire.

[0065] For further information, see Fig.15 The position-limiting retaining rib 52 includes a rotation-stopping portion 521 and a reinforcing rib 522. The second rotation-stopping surface 5211 is provided on the rotation-stopping portion 521. The reinforcing rib 522 connects the rotation-stopping portion 521 and the side wall of the lower hinge groove 13. In this way, the structural strength of the position-limiting retaining rib 52 can be strengthened, so that the rotation-stopping and limiting effect of the position-limiting retaining rib 52 on the position-limiting block 51 is more reliable. In this embodiment, the position-limiting retaining rib 52 is roughly Z-shaped, but is not limited thereto. In other embodiments, the position-limiting retaining rib 52 may also include only the rotation-stopping portion 521 without the reinforcing rib 522, that is, the position-limiting retaining rib 52 is spaced apart from the lower hinge groove 13. The position-limiting retaining rib 52 may also be square, semicircular, L-shaped, T-shaped, U-shaped, or other shapes.

[0066] For further information, see Fig.12 , Fig.15 and Fig.17 , along the axial direction of the lower rotating shaft 60, the matching length L2 of the limit stopper 51 and the limit stop rib 52 is 3mm to 10mm. In this way, it can be ensured that there is a sufficient contact length between the limit stop rib 52 and the limit stopper 51, thereby ensuring the anti-rotation and limiting effect of the limit stop rib 52 on the limit stopper 51; at the same time, the matching length of the limit stopper 51 and the limit stop rib 52 will not be too long to affect the arrangement of the internal structure of the base assembly 10. In some specific embodiments, the length L1 of the limit stopper 51 is 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or any other value within the range of 3mm to 10mm.

[0067] See also Fig.13, along the axial direction of the lower rotating shaft 60, the length L1 of the limit stopper 51 is 3mm to 12mm. In this way, it is ensured that there is a sufficient matching length between the limit stopper 51 and the limit stopper rib 52, thereby ensuring the anti-rotation and limiting effect of the limit stopper rib 52 on the limit stopper 51, and at the same time, the limit stopper 51 will not be too long to affect the arrangement of the internal structure of the base assembly 10. In some specific embodiments, the length L1 of the limit stopper 51 is 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, or any other value within the range of 3mm to 12mm.

[0068] In this embodiment, the end face of the lower rotating shaft 60 connected to one end of the limit stop block 51 is against the side of the stop portion 521 of the limit stop rib 52, L2=L1, but not limited to this. In other embodiments, it can also be L2>L1, or L2<L1, and this application does not impose any limitation on this.

[0069] 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.

[0070] 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.
