Description

Technical Field

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

[0002] A grilling machine generally includes a base assembly and an upper cover assembly. In a conventional grilling machine, the upper cover assembly and the base assembly are not removable. With the development of technology, some grilling machines with removable upper cover assemblies have gradually emerged. This type of grilling machine can either remove the upper cover assembly from the base assembly and use the upper cover assembly and the base assembly separately for cooking, or connect the upper cover assembly and the base assembly together for cooking. In the early stage, the applicant invented a grilling machine, in which the upper cover assembly and the base assembly are removably connected, and when the upper cover assembly is connected to the base assembly, the upper cover assembly and the base assembly are electrically connected through a coupler, and the upper cover assembly and the base assembly are flipped and lifted through a hinge assembly, so that the grilling machine has a closed cover state, a first open cover state in which the upper cover assembly stands upright relative to the base assembly, and a second open cover state in which the upper cover assembly is flipped to one side of the base assembly.

[0003] In order to adapt to the lifting and flipping of the upper cover assembly relative to the base assembly, the lower connector of the coupler is also configured to be able to lift and flip relative to the base assembly. However, the lower connector is an independent component, which is slidably matched and rotated with the base assembly at the same time. When the upper cover assembly rotates from the second cover-opening state to the first cover-opening state, the lower connector switches from rotating with the base assembly to sliding with the base assembly, that is, the lower connector needs to switch the rotation action to the sliding action, which is prone to jamming when switching actions. Affected by the switching action of the lower connector, the upper cover assembly is prone to not rotating smoothly when it rotates from the second cover-opening state to the first cover-opening state. Utility Model Content

[0004] Based on this, it is necessary to provide a grilling machine to solve the problem that the upper cover assembly does not rotate smoothly when it rotates from the second open cover state to the first open cover state.

[0005] A grilling machine comprises a base assembly, an upper cover assembly and a coupler, wherein the upper cover assembly is detachably connected to the base assembly, the coupler comprises a lower connector electrically connected to the electronic components of the base assembly and an upper connector electrically connected to the electronic components of the upper cover assembly, the upper connector is detachably connected to the lower connector, when the upper cover assembly is connected to the base assembly, the upper connector is electrically connected to the lower connector, the upper cover assembly can be lifted and rotated relative to the base assembly, the lower connector comprises a base and an electrical connecting portion for electrically connecting to the upper connector, the electrical connecting portion is rotatably connected to the base, the base assembly is provided with a slide groove extending along its own height direction, the base and the slide groove are slidably matched to realize the lifting and lowering of the lower connector relative to the base assembly.

[0006] The grilling machine provided by the present application has a lower connector including two independent components, a base and an electrical connection part, wherein the base is slidably matched with the slide groove of the base assembly, and the electrical connection part is rotationally matched with the base. It can be seen that the sliding action and the rotation action of the lower connector are respectively realized by different components, and there is no problem of jamming when one component switches between different actions. Therefore, the upper cover assembly rotates very smoothly, which solves the problem of the upper cover assembly not rotating smoothly when rotating from the second open cover state to the first open cover state.

[0007] In one embodiment, the lower connector also includes an elastic reset member for resetting the rotation of the electrical connection part. When the upper cover assembly is connected to the base assembly, the upper connector is connected to the electrical connection part, and the electrical connection part rotates with the rotation of the upper connector; when the upper cover assembly is connected and disconnected from the base assembly, the upper connector is disconnected from the electrical connection part, and the elastic reset member resets the electrical connection part.

[0008] In this way, the rotation of the electrical connection part is reset by providing an elastic reset member, so that the electrical connection part returns to its original state, thereby facilitating quick connection between the upper connector and the electrical connection part when the upper cover assembly is connected to the base assembly.

[0009] In one of the embodiments, the base includes a bottom and two support portions disposed on the bottom and spaced apart from each other, and the electrical connection portion is rotatably mounted between the two support portions.

[0010] In this way, the two supporting parts play a role of supporting and installing the electrical connecting part, so that the rotation of the electrical connecting part is more stable.

[0011] In one embodiment, the supporting portion is provided with a rotating hole, and rotating shafts are provided at both ends of the electrical connecting portion. The rotating shafts extend into the rotating hole and rotate with the rotating hole. The elastic return member is configured as a torsion spring, which is sleeved on the rotating shaft, and one end of the torsion spring is fixed to the electrical connecting portion, and the other end is fixed to the base.

[0012] Thus, the structure is very simple and the fit is compact. The rotating shaft not only serves as a component that rotates with the supporting part, but also serves as a limiter for the torsion spring, which can prevent the torsion spring from falling off and becoming ineffective.

[0013] In one embodiment, the electrical connection portion is provided with a first plug hole, the support portion is provided with a second plug hole, one end of the torsion spring is inserted into the first plug hole, and the other end is inserted into the second plug hole.

[0015] In one embodiment, the electrical connection part includes a first shell, a slot is provided at one end of the first shell, and an electrode plug electrically connected to the electronic components of the base assembly is provided in the slot. The upper connector includes a second shell, a receiving groove is provided in the second shell, and an electrode column electrically connected to the electronic components of the upper cover assembly is provided in the receiving groove. When the upper connector is connected to the electrical connection part, the end of the first shell with the slot is inserted into the receiving groove, and the electrode column is inserted into the slot and contacts with the electrode plug.

[0016] The first shell can be provided to hide the electrode plug inside, and the second shell can be provided to hide the electrode column inside, so that when the upper connector and the lower connector are disassembled, the electrode plug and the electrode column will not be exposed, so that it is safer to use. At the same time, when the upper connector is connected to the electrical connection part, one end of the first shell is inserted into the accommodating groove, and the electrode column is inserted into the slot, so that the upper connector is tightly connected to the electrical connection part and is not easy to loosen, thereby ensuring that the electrode column is in contact with the electrode plug to achieve electrical connection.

[0017] In one embodiment, a stopper is provided on the surface of the first shell to limit the depth of the first shell inserted into the accommodating groove.

[0018] In this way, it is possible to avoid the situation where the electrical connection part is completely inserted into the receiving groove, which makes it difficult to disassemble the electrical connection part and the upper connector.

[0019] In one of the embodiments, a positioning structure is provided between the first shell and the second shell, and the positioning structure includes a positioning rib and a positioning groove, and the positioning rib cooperates with the positioning groove to achieve a positioning connection between the electrical connection part and the upper connector.

[0020] Usually, the upper connector and the lower connector are both set to a symmetrical structure, which is simple in structure and beautiful in appearance. The symmetrical structure can be installed in both the forward and reverse directions. When the upper connector and the lower connector are installed in the forward direction, the neutral wire is paired with the neutral wire, and the live wire is paired with the live wire; when the upper connector and the lower connector are installed in the reverse direction, the neutral wire is paired with the live wire. This embodiment can avoid the upper connector and the lower connector from being installed in reverse by setting a positioning structure, ensuring that the neutral wire and the live wire of the upper connector and the lower connector are accurately paired.

[0021] In one embodiment, the positioning rib is provided on the first shell surface, and the positioning groove is provided on the side wall of the receiving groove; or, the positioning rib is provided on the side wall of the receiving groove, and the positioning groove is provided on the first shell surface.

[0022] In this way, the structure is very simple and easy to process, and the positioning ribs and positioning grooves are easy to identify when assembling the coupler during the production process, so that the relative positions of the electrical connection part and the upper connector can be positioned according to the positioning ribs and positioning grooves.

[0023] In one of the embodiments, it also includes a hinge assembly, which is rotatably connected to the upper cover assembly, the base assembly is provided with a hinge groove, the hinge assembly is detachably connected to the hinge groove, the hinge assembly can move up and down in the hinge groove and the hinge assembly can rotate when moving to the upper end of the hinge groove, the upper connector is arranged at one end of the hinge assembly, the lower connector is arranged in the hinge groove, the slide groove is arranged on the side wall of the hinge groove, and both ends of the base extend into the slide groove and slide with the slide groove.

[0024] In this way, the upper cover assembly and the base assembly can be detachably connected by the hinge assembly being detachably connected to the hinge groove. The upper connector is arranged at one end of the hinge assembly, and the upper connector moves together with the hinge assembly. When the hinge assembly is inserted into the hinge groove and connected to the base assembly, the upper connector can be close to the lower connector and connected to the lower connector. When the hinge assembly is removed from the hinge groove, the upper connector can be disassembled from the lower connector, so that the mechanical connection and electrical connection of the upper cover assembly and the base assembly can be carried out simultaneously.

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

[0044] See also Figures 1 to 3The present application provides a grilling machine, including a base assembly 10 and an upper cover assembly 20. The upper cover assembly 20 is detachably connected to the base assembly 10, so that the upper cover assembly 20 and the base assembly 10 can be disassembled and used separately for cooking; or the upper cover assembly 20 and the base assembly 10 can be connected so that the upper cover assembly 20 and the base assembly 10 can be used together for cooking.

[0045] When the upper cover assembly 20 is connected to the base assembly 10, the upper cover assembly 20 can be lifted and rotated relative to the base assembly 10, so that the grilling machine has a closed state, a first open state in which the upper cover assembly 20 stands 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°. In the closed state, the upper cover assembly 20 can be raised and lowered relative to the base assembly 10, so that when cooking thick food or food that is easy to expand, the food can lift up the upper cover assembly 20, thereby maintaining the soft taste of the food. Figure 4 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 115°, for example, θ is 90°, 93°, 95°, 98°, 110°, 112°, or 115°, etc. Figure 3 As shown, preferably θ>90° to avoid accidental touch causing the upper cover assembly 20 to close. Figure 5 As shown, in the second open cover state, the angle between the upper cover assembly 20 and the base assembly 10 is approximately 180°.

[0046] See also Figure 1 , Figure 6 and Figure 7 The grilling machine further includes a coupler 30, which includes a lower connector 31 electrically connected to the electronic components of the base assembly 10 and an upper connector 32 electrically connected to the electronic components of the upper cover assembly 20, and the upper connector 32 is detachably connected to the lower connector 31. When the upper cover assembly 20 is connected to the base assembly 10, the upper connector 32 is electrically connected to the lower connector 31. Figure 6 When the upper cover assembly 20 and the base assembly 10 are disassembled, the upper connector 32 and the lower connector 31 are disassembled, and the upper connector 32 and the lower connector 31 are electrically disconnected, as shown Figure 7 shown.

[0047] like Figure 8As shown, the lower connector 31 includes a base 311 and an electrical connection portion 312 for electrically connecting to the upper connector 32, and the electrical connection portion 312 is rotatably connected to the base 311. Fig. 9 As shown, the base assembly 10 is provided with a slide groove 11 extending along its own height direction, and the base 311 slides with the slide groove 11 to realize the lifting and lowering of the lower connector 31 relative to the base assembly 10. In this way, the lower connector 31 includes two independent components, the base 311 and the electrical connection part 312, wherein the base 311 slides with the slide groove 11 of the base assembly 10, and the electrical connection part 312 rotates with the base 311. It can be seen that the sliding action and the rotation action of the lower connector 31 are respectively realized by different components, and there is no problem of stagnation when one component switches different actions, so that the upper cover assembly 20 rotates very smoothly, which solves the problem of the upper cover assembly rotating unsmoothly when the upper cover assembly rotates from the second open cover state to the first open cover state.

[0048] See also Figure 1 , Figure 3 , Figure 6 and Figure 7 Furthermore, the grilling machine further comprises a hinge assembly 40, which is rotatably connected to the upper cover assembly 20, and the base assembly 10 is provided with a hinge slot 12, and the hinge assembly 40 is detachably connected to the hinge slot 12, so that the upper cover assembly 20 and the base assembly 10 can be detachably connected. The hinge assembly 40 can move up and down in the hinge slot 12, and the hinge assembly 40 can rotate when it moves to the upper end of the hinge slot 12, so that the upper cover assembly 20 can be lifted and rotated relative to the base assembly 10, so that the grilling machine can have the above-mentioned closed cover state, the first open cover state and the second open cover state, and in the closed cover state, the upper cover assembly 20 can be lifted and rotated relative to the base assembly 10.

[0049] See also Figure 6 , Figure 7 and Fig. 9 In this embodiment, the upper connector 32 is arranged at one end of the hinge assembly 40, the lower connector 31 is arranged in the hinge slot 12, the slide slot 11 is arranged on the side wall of the hinge slot 12, and the two ends of the base 311 extend into the slide slot 11 and slide with the slide slot 11. In this way, the upper connector 32 moves with the hinge assembly 40. When the hinge assembly 40 is inserted into the hinge slot 12 and connected with the base assembly 10, the upper connector 32 can be close to the feed connector and connected with the lower connector 31. When the hinge assembly 40 is removed from the hinge slot 12, the upper connector 32 can be disassembled from the lower connector 31, so that the mechanical connection and electrical connection of the upper cover assembly 20 and the base assembly 10 can be carried out simultaneously.

[0050] like Figure 7As shown, the upper connector 32 is received inside one end of the hinge assembly 40. In this way, the hinge assembly 40 can protect the upper connector 32, and the upper connector 32 is hidden, and the appearance is more beautiful. Further, the upper connector 32 can be fixedly connected to the hinge assembly 40 by fasteners, or can be fixedly connected to the hinge assembly by means of clamping, bonding or integral injection molding, and the present application does not limit this.

[0051] Please combine Figure 2 and Fig. 9 When the grilling machine is in the closed state and the upper cover assembly 20 is lifted or lowered relative to the base assembly 10, the hinge assembly 40 moves up and down in the hinge slot 12, and accordingly, the base 311 of the lower connector 31 moves up and down along the slide slot 11. When the hinge assembly 40 moves to the upper end of the hinge slot 12, the hinge assembly 40 can rotate at the opening at the upper end of the hinge slot 12, so that the upper cover assembly 20 can rotate to the second open state. When the hinge assembly 40 rotates at the upper end of the hinge slot 12, the upper connector 32 rotates with the hinge assembly 40, and the electrical connection portion 312 rotates with the upper connector 32, so that in the second open state, the upper connector 32 and the electrical connection portion 312 can maintain electrical connection.

[0052] See also Figures 10 to 12 , further, the lower connector 31 also includes an elastic reset member 313 for resetting the rotation of the electrical connection part 312. When the upper cover assembly 20 is connected to the base assembly 10, the upper connector 32 is connected to the electrical connection part 312, and the electrical connection part 312 rotates with the rotation of the upper connector 32; when the upper cover assembly 20 is connected and disassembled from the base assembly 10, the upper connector 32 and the electrical connection part 312 are disassembled, and the elastic reset member 313 resets the electrical connection part 312. In this way, by setting the elastic reset member 313 to reset the rotation of the electrical connection part 312, the electrical connection part 312 is restored to its original state, thereby facilitating the quick connection between the upper connector 32 and the electrical connection part 312 when the upper cover assembly 20 is connected to the base assembly 10. In addition, when the upper cover assembly 20 rotates from the second open cover state to the first open cover state, the elastic action of the elastic reset member 313 makes the upper cover assembly 20 rotate more smoothly. After the upper cover assembly 20 is removed, the electrical connection portion 312 is automatically reset under the action of the elastic reset member 313 , and the base 311 can move downward along the slide slot 11 under the action of gravity, thereby preventing the lower connector 31 from being stuck at the upper end of the slide slot 11 .

[0053] See also Figures 10 to 12 Further, the base 311 includes a bottom 3111 and two support parts 3112 arranged on the bottom 3111 and spaced apart, and the electrical connection part 312 is rotatably mounted between the two support parts 3112. In this way, the two support parts 3112 support and mount the electrical connection part 312, so that the rotation of the electrical connection part 312 is more stable.

[0054] In one embodiment, the support portion 3112 is provided with a rotating hole 3113, and rotating shafts 3121 are provided at both ends of the electrical connection portion 312. The rotating shaft 3121 extends into the rotating hole 3113 and rotates with the rotating hole 3113. The elastic reset member 313 is configured as a torsion spring, which is sleeved on the rotating shaft 3121, and one end of the torsion spring is fixed to the electrical connection portion 312, and the other end is fixed to the base 311. In this way, the structure is very simple and the cooperation is compact. The rotating shaft 3121 not only serves as a component that rotates with the support portion 3112, but also serves as a limiter of the torsion spring, which can prevent the torsion spring from falling off and failing.

[0055] Furthermore, the electrical connection portion 312 is provided with a first plug hole 3122, the support portion 3112 is provided with a second plug hole 3114, one end of the torsion spring is inserted into the first plug hole 3122, and the other end is inserted into the second plug hole 3114. In this way, the structure is very simple and easy to assemble.

[0056] In this embodiment, a boss 3123 is provided between the electrical connection portion 312 and the rotating shaft 3121, and the first plug hole 3122 is provided on the boss 3123. When installing the torsion spring, the main body of the torsion spring is sleeved on the outside of the rotating shaft 3121, one end of the torsion spring is inserted into the first plug hole 3122, and the other end of the torsion spring is inserted into the second plug hole 3114. The two ends of the main body of the torsion spring can respectively abut against the boss 3123 and the bottom wall of the rotating hole 3113. Of course, in other embodiments, the first plug hole can also be directly provided on the end surface of the electrical connection portion where the rotating shaft is provided.

[0057] Further, the electrical connection part 312 includes a first shell 3124, one end of which is provided with a slot 3125, and an electrode plug 3126 electrically connected to the electronic components of the base assembly 10 is provided in the slot 3125. The upper connector 32 includes a second shell 321, and a receiving groove 322 is provided in the second shell 321, and an electrode column 323 electrically connected to the electronic components of the upper cover assembly 20 is provided in the receiving groove 322. When the upper connector 32 is connected to the electrical connection part 312, one end of the first shell 3124 provided with the slot 3125 is inserted into the receiving groove 322, and the electrode column 323 is inserted into the slot 3125 and contacts with the electrode plug 3126. The first shell 3124 can hide the electrode plug 3126 inside, and the second shell 321 can hide the electrode column 323 inside, so that when the upper connector 32 is disassembled from the lower connector 31, the electrode plug 3126 and the electrode column 323 will not be exposed outside, so that it is safer to use. At the same time, when the upper connector 32 is connected to the electrical connection part 312, one end of the first shell 3124 is inserted into the accommodating groove 322, and the electrode column 323 is inserted into the slot 3125, so that the upper connector 32 is tightly connected to the electrical connection part 312 and is not easy to loosen, thereby ensuring that the electrode column 323 is in contact with the electrode plug 3126 to achieve electrical connection.

[0058] Furthermore, a stopper 3127 is provided on the surface of the first housing 3124 to limit the depth of the first housing 3124 inserted into the receiving groove 322. In this way, the electrical connection part 312 can be prevented from being fully inserted into the receiving groove 322, which makes it difficult to disassemble the electrical connection part 312 and the upper connector 32.

[0059] For further information, see Fig.11 A positioning structure 33 is provided between the first shell 3124 and the second shell 321. The positioning structure 33 includes a positioning rib 331 and a positioning groove 332. The positioning rib 331 cooperates with the positioning groove 332 to realize the positioning connection between the electrical connection part 312 and the upper connector 32. Usually, the upper connector 32 and the lower connector 31 are both set to a symmetrical structure, which has a simple structure and a beautiful appearance. The symmetrical structure can be installed in both the forward and reverse directions. When the upper connector 32 and the lower connector 31 are installed forward, the neutral wire is paired with the neutral wire, and the live wire is paired with the live wire; when the upper connector 32 and the lower connector 31 are installed in reverse, the neutral wire is paired with the live wire. In this embodiment, by providing a positioning structure 33, it is possible to avoid the upper connector 32 and the lower connector 31 from being installed reversely, thereby ensuring that the neutral wire and the live wire of the upper connector 32 and the lower connector 31 are accurately paired.

[0060] like Fig.11 As shown, in one embodiment, the positioning rib 331 is provided on the surface of the first shell 3124, and the positioning groove 332 is provided on the side wall of the accommodating groove 322. In this way, the structure is very simple and easy to process, and the positioning rib 331 and the positioning groove 332 are easy to be identified when assembling the coupler 30 during the production process, so that the relative positions of the electrical connection part 312 and the upper connector 32 can be positioned according to the positioning rib 331 and the positioning groove 332.

[0061] In another embodiment, the positioning rib is provided on the side wall of the accommodating groove, and the positioning groove is provided on the surface of the first shell body. The structure is also very simple and easy to process, and the positioning rib and the positioning groove are easy to identify when assembling the coupler during the production process, so that the relative positions of the electrical connection part and the upper connector can be positioned according to the positioning rib and the positioning groove.

[0062] In this embodiment, the positioning rib 331 is only provided on one side of the first shell 3124 , and the positioning groove 332 is only provided on one side of the receiving groove 322 , so as to ensure that the positioning rib 331 cooperates with the positioning groove 332 to play a positioning role.
