[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the related art, the traditional oven has a fixed cavity and a fixed heating tube, and can only be used for baking or roasting, but not for hot pot, and has a single function. The electric baking pan is mainly used for making pancakes, but cannot be used for baking or roasting, and cannot be used for hot pot or roasting. It can only process pancake-shaped foods, and has a single function. The multi-functional pot structure can be regarded as an electric heating tube heating furnace, which can only be used for cooking hot pot or frying and roasting, but not baking; there is only one pot, and it cannot be used for frying and roasting while making hot pot, and has a single function.

[0045] That is to say, the cooking utensils in the related art, such as ovens, electric baking pans and multifunctional pots, have the disadvantage of single functions. To this end, the present application proposes a cooking utensil 200, which has different cooking modes and rich functions, thereby being conducive to meeting the diverse cooking needs of users.

[0046] The following describes a cooking appliance 200 according to an embodiment of the present invention with reference to the accompanying drawings. The cooking appliance 200 may be, for example, a folding oven.

[0047] Reference Figure 1 and Figure 2 According to the cooking appliance 200 of the embodiment of the present invention, the cooking appliance 200 has a first cooking mode and a second cooking mode, and the cooking appliance 200 includes: a first cooking cavity 210, a second cooking cavity 220, a hinge assembly 100 and a controller.

[0048] Specifically, a first heating element 2101 and a first temperature control unit 212 are provided in the first cooking cavity 210; a second heating element 221 and a second temperature control unit 222 are provided in the second cooking cavity 220. The first temperature control unit 212 and the second temperature control unit 222 may be, for example, a thermostat. The first heating element 2101 and the first temperature control unit 212 facilitate the corresponding control of the heating temperature or firepower of the first cooking cavity 210, and the second heating element 221 and the second temperature control unit 222 facilitate the corresponding control of the heating temperature or firepower of the second cooking cavity 220. Thus, the heating processes of the first cooking cavity 210 and the second cooking cavity 220 can be controlled independently, which is conducive to better meeting the needs of users.

[0049] Reference Fig.10 , Fig.10 1 is an exploded view of a hinge assembly 100 in a cooking appliance 200 according to an embodiment of the present invention, wherein the hinge assembly 100 comprises: a first hinge seat 1, a second hinge seat 2, a hollow pivot shaft 3, a stopper 4 and a reset member 5. The first hinge seat 1 is connected to a first cooking cavity 210; the second hinge seat 2 is connected to a second cooking cavity 220.

[0050] Reference Figure 7, a sensing element 7 is provided on one of the first hinge seat 1 and the second hinge seat 2, and a triggering part 23 for triggering the sensing element 7 is provided on the other of the first hinge seat 1 and the second hinge seat 2. Therefore, the relative angle relationship between the first hinge seat 1 and the second hinge seat 2 can be obtained more sensitively through the sensing device 7, which increases the accuracy of the device in performing corresponding work instructions according to the angle information.

[0051] For example, the first hinge seat 1 may be provided with a sensing element 7 (such as a state switching switch, etc.), and the second hinge seat 2 may be provided with a triggering portion 23 (such as a triggering button, etc.) for triggering the sensing element 7. Alternatively, the second hinge seat 2 may be provided with a sensing element 7, and the first hinge seat 1 may be provided with a triggering portion 23 for triggering the sensing element 7.

[0052] The controller may communicate with the sensing element 7 to control the cooking mode of the cooking appliance 200 .

[0053] According to the cooking appliance 200 of the embodiment of the present invention, by integrating the sensing device 7 inside the first hinge seat 1 or the second hinge seat 2, different hinge positions can be identified so as to match different control logics to control the device and obtain a better experience.

[0054] In some optional embodiments of the present invention, the sensing device 7 may be a micro switch or a ball switch. Of course, the present invention is not limited thereto. In some optional embodiments of the present invention, the sensing device 7 may also be, for example, a non-contact sensor, etc. Thus, by making the sensing device 7 a non-contact sensor, less material is required, and the appearance is not damaged or affected. The specific form of the sensing device 7 can be adaptively selected according to actual needs.

[0055] Specifically, the first hinge seat 1 has a first hollow shaft 11; the second hinge seat 2 is pivotally connected to the first hinge seat 1, and the second hinge seat 2 has a second hollow shaft 21, which is coaxially arranged with the first hollow shaft 11, and the inner diameter and outer diameter of the second hollow shaft 21 are equal to those of the first hollow shaft 11, and the hinge assembly 100 is configured to be locked when the second hinge seat 2 is at a predetermined angle with the first hinge seat 1. As a result, the hinge assembly 100 can be locked and suspended at a predetermined angle, which is conducive to meeting the diverse needs of users.

[0056] In some optional embodiments of the present invention, the predetermined angle may be in the range of 95 to 135 degrees, for example, the predetermined angle may be 95, 100, 115, 120, 125, 135, etc. When the hinge assembly 100 is applied to the cooking utensil 200, if the predetermined angle is less than 95 degrees, it is inconvenient for the user to operate, and if the predetermined angle is greater than 135 degrees, the center of gravity of the cooking utensil 200 moves backwards, making it easy to tip over and increasing the occupied space.

[0057] The present application sets the predetermined angle within the range of 95 to 135 degrees. When the hinge assembly 100 is used on the cooking utensil 200, the second hinge seat 2 is rotated relative to the first hinge seat 1 and then locked, which is not only convenient for user operation but also has good stability and saves space.

[0058] The hollow pivot shaft 3 is passed through the first hollow shaft 11 and the second hollow shaft 21. The hollow pivot shaft 3 is suitable for the wiring harness to pass through. The wiring harness may include a power cord of a high-power source, a control cord, etc. By passing the wiring harness through the hollow pivot shaft 3, not only is wiring convenient, but exposure of the wiring harness can also be effectively avoided, thereby improving the safety of use and the neatness of the appearance of the hinge assembly 100.

[0059] In addition, when the hollow pivot shaft 3 is removed, the wire harness can be removed, which is convenient for the removal of the wire harness. In some embodiments of the present invention, the wire harness can be a flexible wire body, which is convenient for assembling the wire harness into the hollow pivot shaft 3.

[0060] Here, the hollow pivot shaft 3 refers to a part of the pivot shaft that is hollow, which makes it easy to pass the line through the hollow part of the pivot shaft and connect other components at the non-hollow position of the pivot shaft. This is beneficial to improving the structural strength of the hollow pivot shaft 3, thereby helping to improve the reliability of the hinge assembly 100.

[0061] A first limiting portion 31 is formed on the hollow pivot shaft 3, the limiting member 4 is connected to the hollow pivot shaft 3 by a fastener 5, and a second limiting portion 41 matching the first limiting portion 31 is formed on the limiting member 4. For example, a first limiting portion 31 may be formed on the hollow pivot shaft 3, the limiting member 4 is connected to the hollow pivot shaft 3 by a fastener 5, and a second limiting portion 41 may be formed on the limiting member 4, and the second limiting portion 41 matches the first limiting portion 31, thereby, through the cooperation of the first limiting portion 31 and the second limiting portion 41, the hinge assembly 100 can be locked after the second hinge seat 2 rotates to a predetermined angle relative to the first hinge seat 1, and the hinge assembly 100 can also withstand the torque generated by the suspension of a large-mass connecting member.

[0062] When the hinge assembly 100 is applied to the cooking appliance 200, the cooking appliance 200 can have a variety of working modes, such as partial opening and closing, limited suspension, and full 180-degree unfolding as required.

[0063] The limit member 4 is constructed to be convertible between a locking position and a release position. In the locking position, the limit member 4 is connected to the hollow pivot shaft 3 by a fastener 5, and the second hinge seat 2 of the hinge assembly 100 is in a suspended locking state at a predetermined angle with the first hinge seat 1. In the release position, the second hinge seat 2 can rotate freely relative to the first hinge seat 1.

[0064] The reset member 6 is sleeved on the outside of the fastener 5 and connected to the stopper 4. For example, the reset member 6 can be an elastic member such as a spring, etc., and the reset member 6 can be sleeved on the outside of the fastener 5, and the reset member 6 can be connected to the stopper 4. Thus, the reset member 6 can provide the stopper 4 with the force required for resetting.

[0065] For example, the second hinge seat 2 of the hinge assembly 100 is pivotally connected to the first hinge seat 1, and the hinge assembly 100 is in a first position (refer to Figure 7 ) and the second position (ref. Figure 8 ), in the first position, the second hinge seat 2 is coplanar with the first hinge seat 1; in the second position, the second hinge seat 2 and the first hinge seat 1 are at an angle of approximately 180 degrees; the hinge assembly 100 also has a third position (refer to Fig. 9 ), in the third position, the first hinge seat 1 and the second hinge seat 2 form an included angle of a predetermined angle, and the hinge assembly 100 is configured to be lockable in the third position.

[0066] When the hinge assembly 100 needs to be transferred from the first position to the second position, the hinge assembly 100 passes through the third position. At the third position, the second limiting portion 41 matches the first limiting portion 31 to lock the hinge assembly 100.

[0067] When the locked state needs to be released, for example, when the hinge assembly 100 is converted from the third position to the second position, the limit member 4 can be controlled (for example, moved) to the release position to release the locked state between the first hinge seat 1 and the second hinge seat 2, and the angle between the first hinge seat 1 and the second hinge seat 2 is adjusted so that the hinge assembly 100 is in the second position. During this process, the limit member 4 can be reset under the action of the reset member 6.

[0068] When the hinge assembly 100 needs to be converted from the second position to the first position, it will pass through the third position. At the third position, the second limiting portion 41 matches the first limiting portion 31 to lock the hinge assembly 100.

[0069] When the locked state needs to be released, for example, when the hinge assembly 100 is converted from the third position to the first position, the limit member 4 can be controlled (for example, moved) to the release position to release the locked state between the first hinge seat 1 and the second hinge seat 2, and the angle between the first hinge seat 1 and the second hinge seat 2 is adjusted so that the hinge assembly 100 is in the first position. During this process, the limit member 4 can be reset under the action of the reset member 6.

[0070] According to the hinge assembly 100 of the embodiment of the present invention, the angle relationship between the first hinge seat 1 and the second hinge seat 2 can be adjusted according to actual needs, and the limiter 4 can keep the first hinge seat 1 and the second hinge seat 2 at a specific opening and closing angle. Therefore, the hinge assembly 100 can adapt to multi-mode scene operation and better meet the diverse needs of users.

[0071] The controller of the cooking appliance 200 is used to control the cooking appliance to switch between different cooking modes. The controller can be electrically connected to the sensing device 7 to switch the cooking mode according to the detection angle. The cooking appliance 200 can be a double-sided heating cooking device, such as an electric pancake rack, a fish grill, etc.

[0072] In some embodiments of the present invention, the controller can automatically match the corresponding working program and control mode according to the angular relationship between the first hinge seat 1 and the second hinge seat 12 detected by the sensing device 7, thereby eliminating the process of manual operation of the cooking appliance 200 and improving the user experience.

[0073] Reference Figure 3 , Figure 4 as well as Figure 8 In some embodiments of the present invention, when the hinge assembly 100 is closed, the outer surfaces of the first hinge seat 1 and the second hinge seat 2 are almost in contact with each other, and the triggering part 23 triggers the sensing device 7, and the controller receives the signal to control the cooking utensil 200 to work in the corresponding mode; when the hinge assembly 100 is fully opened (refer to Figure 1 , Figure 2 as well as Figure 7 ) or partially open (refer to Figure 5 , Figure 6 as well as Fig. 9 ), the first hinge seat 1 and the second hinge seat 2 are out of the fitted state, at which time the sensing device 7 returns to its original position, and the controller receives the return signal to control the cooking appliance 200 to work in the corresponding mode.

[0074] It should be noted that the controller can select from a variety of cooking modes according to the purpose of the cooking appliance 200. The above is just an example and not a limitation on the types of cooking modes.

[0075] According to the cooking utensil 200 of the embodiment of the present invention, the hinge assembly 100 allows the first cooking cavity 210 and the second cooking cavity 220 of the cooking utensil 200 to have a variety of opening and closing angles, can meet a variety of working modes, and is easy to disassemble. The controller can automatically match the corresponding working program and control mode according to the opening and closing angle information, thereby improving the user experience.

[0076] In some optional embodiments of the present invention, the first heating element 2101 and the second heating element 221 may also adopt heat source devices of different properties (such as steaming, baking, etc.), which is conducive to achieving more refined cooking control and effects.

[0077] According to the cooking utensil 200 of the embodiment of the present invention, by providing the hinge assembly 100, and connecting the first hinge seat 1 with the first cooking cavity 210, and connecting the second hinge seat 2 with the second cooking cavity 220, the shape and working mode of the cooking utensil 200 can be freely combined as needed. Thus, the cooking utensil 200 has different cooking modes, enriching the functions of the cooking utensil 200, and thus helping to meet the diverse cooking needs of users.

[0078] According to some embodiments of the present invention, a first support frame 213 is disposed in the first cooking cavity 210. Figure 2 The longitudinal section of the first support frame 213 may be L-shaped, and the first heating element 2101 is suitable for being connected to the first cooking cavity 210 through the first support frame 213. Thus, the first heating element 2101 is easily installed in the first cooking cavity 210 through the first support frame 213.

[0079] A second support frame 223 is disposed in the second cooking cavity 220. Figure 4 The longitudinal section of the second support frame 223 may be L-shaped, and the second heating element 221 is suitable for being connected to the second cooking cavity 220 through the second support frame 223. Thus, the second heating element 221 is easily installed in the second cooking cavity 220 through the second support frame 223.

[0080] In some embodiments of the present invention, the outer contour of the cooking appliance 200 is substantially configured to be a quadrilateral (eg, a rectangle) or an ellipse.

[0081] Further, the first support frame 213 is configured to extend along the length direction of the cooking utensil 200, and the first support frame 213 may include one or more first support frames, and a first mounting groove 2131 is formed on the first support frame 213, and the first heating element 2101 is suitable for being mounted in the first mounting groove 2131. Thus, the first mounting groove 2131 facilitates reliable mounting of the first heating element 2101 on the first support frame 213.

[0082] The second support frame 223 is configured to extend along the length direction of the cooking utensil 200, and the second support frame 223 may include one or more second support frames, and a second mounting groove 2231 is formed on the second support frame 223, and the second heating element 221 is suitable for being mounted in the second mounting groove 2231. Thus, the second mounting groove 2231 facilitates reliable mounting of the second heating element 221 on the second support frame 223.

[0083] Furthermore, the cooking appliance 100 may further include a first pot body 240 and a second pot body 250; the first pot body 240 may be detachably disposed in the first cooking cavity, and the second pot body 250 may be detachably disposed in the second cooking cavity.

[0084] The first heating element 2101 may be a first heating tube, and the side of the first heating tube in contact with the first pot body 240 is configured as a plane. Therefore, by configuring the side of the first heating tube in contact with the first pot body 240 as a plane, it is helpful to ensure the flatness of the side of the first heating tube in contact with the first pot body 240, and the contact area between the first heating element 2101 and the first pot body 240 can be increased, so as to ensure the heating efficiency and heating uniformity, and ensure the taste of the cooked food.

[0085] The second heating element 221 may be a second heating tube, and the side of the second heating tube in contact with the second pot body 250 is configured as a plane. Therefore, by configuring the side of the second heating tube in contact with the second pot body 250 as a plane, it is helpful to ensure the flatness of the side of the second heating tube in contact with the second pot body 250, and the contact area between the second heating element 221 and the second pot body 250 can be increased, so as to ensure the heating efficiency and heating uniformity, and ensure the taste of the cooked food.

[0086] Furthermore, the first heating tube and the second heating tube are bent into an M shape or a serpentine shape, thereby facilitating the uniformity of heating and improving the taste of cooked food.

[0087] In some specific embodiments of the present invention, the first heating tube and the second heating tube are both circular heating tubes, and the first support frame 213 and the second support frame 223 can each include two. In order to better balance the problem of power and efficiency, the first heating tube and the second heating tube are bent into an M shape, and the top of the circular heating tube is flattened and fixed with two support frames. For example, two first support frames 213 fix the first heating element 2101, and two second support frames 223 fix the second heating element 221. This is conducive to ensuring the flatness of the side of the heating tube that contacts the pot body, increasing the overall rigidity and the contact area with the pot body, thereby facilitating the heating efficiency and heating uniformity.

[0088] In some embodiments of the present invention, the cooking appliance 200 may further include a grill, which is detachably mounted on the first cooking cavity 210 in the first cooking mode. In the second cooking mode, the first pot 240 is disposed in the first cooking cavity 210, and the second pot 250 is disposed in the second cooking cavity 220.

In the second cooking mode, the cooking utensil 200 can have the function of a multifunctional electric hot pot.

[0090] According to some embodiments of the present invention, the controller includes a computer board disposed at the front side of the first cooking cavity 210, and the controller independently controls the first heating element 2101 and the second heating element 221. For example, the controller may include a computer board, and the computer board may be disposed at the front side of the interior of the first cooking cavity 210, and the controller independently controls the first heating element 2101 and the second heating element 221, so as to facilitate independent control of the temperature or firepower in the first cooking cavity 210 and the second cooking cavity 220.

[0091] The cooking utensil 200 may be provided with a control knob, and the cooking utensil 200 may adopt an electronic temperature control method, so that the temperature control and the fire power control are more flexible and changeable; by matching the software, it can adapt to different application scenarios, making the operation experience more user-friendly.

[0092] According to some embodiments of the present invention, the cooking appliance 200 may further include: a duct cooling system, which is arranged in the first cooking cavity 210. Furthermore, the duct cooling system may be arranged on the front side of the first cooking cavity 210. Thus, on the one hand, heat can be dissipated to ensure the temperature rise under the condition of small volume and high power, and on the other hand, the structure of the cooking appliance 200 is made more compact.

[0093] In some specific embodiments of the present invention, the hollow pivot shaft 3, the limit member 4, the fastener 5 and the reset member 6 can be assembled into a shaft assembly. During the assembly of the hinge assembly 100, after the second hinge seat 2 is assembled to the first hinge seat 1, the shaft assembly is assembled with the second hinge 2 and the first hinge seat 1 respectively. Thus, the hinge assembly 100 can be easily integrated into a modular structure and can be easily expanded to various devices requiring similar functions.

[0094] According to the hinge assembly 100 of the embodiment of the present invention, the inside of the hollow pivot shaft 3 can pass the power line, control line, etc. of the power source, and it is convenient to assemble and disassemble; through the cooperation of the first limit portion 31 and the second limit portion 41, the hinge assembly 100 can be locked after the second hinge seat 2 rotates the predetermined angle relative to the first hinge seat 1. Therefore, the hinge assembly 100 can not only have the function of passing the line, but also enable the hinge assembly 100 to adapt to multi-mode scene operation and better meet the diverse needs of users. In addition, the hinge assembly 100 can be easily integrated into a modular structure, and can be easily expanded to various devices that require similar functions.

[0095] Further, refer to Fig. 9 The first hinge seat 1 also includes a first hinge seat body 12, and the second hinge seat 2 also includes a second hinge seat body 22. In some specific embodiments of the present invention, the first hollow shaft 11 can be arranged on one side of the first hinge body 12; the second hollow shaft 21 is arranged on one side of the second hinge body 22; and the first hinge body 12 and the second hinge body 22 are formed with wire holes suitable for the wiring harness to pass through.

[0096] Further, refer to Fig.10 In some specific embodiments of the present invention, the first hinge seat body 12 and the second hinge seat body 22 are both constructed in a rectangular shape, and the first hollow shaft 11 includes two first hollow shafts 11, which are respectively located at the two ends of the first hinge seat body 12 along the length direction, and the second hollow shaft 21 is arranged at the middle position of the second hinge seat body 22 along the length direction.

[0097] A fixing structure 121 is formed on one of the first hinge body 12 and the second hinge body 22, and the fixing structure 121 is suitable for installing the sensing device 7. For example, the fixing structure 121 suitable for installing the sensing device 7 may be formed on the first hinge body 12, or the fixing structure 121 suitable for installing the sensing device 7 may be formed on the second hinge body 22. Thus, the fixing structure 121 facilitates the installation of the sensing device 7 on the first hinge body 12 or the second hinge body 22.

[0098] Optionally, refer to Figure 7A matching hole 13 corresponding to the trigger point 71 of the induction device 7 is formed on one of the first hinge seat 1 and the second hinge seat 2, and a trigger portion 23 for triggering the trigger point 71 is formed on the other of the first hinge seat 1 and the second hinge seat 2. Therefore, when the hinge assembly 100 is applied to the cooking utensil 200, the cooking utensil 200 can be placed in one cooking mode by triggering the trigger point 71 through the trigger portion 23, and the cooking utensil 200 can be placed in another cooking mode when the trigger portion 23 releases the trigger point 71, thereby helping to meet the diverse cooking needs of users.

[0099] For example, the first hinge seat 1 may be formed with a matching hole 13 corresponding to the trigger point 71, and the second hinge seat 2 may be formed with a trigger portion 23 for triggering the trigger point 71. Alternatively, the second hinge seat 2 may be formed with a matching hole 13 corresponding to the trigger point 71, and the first hinge seat 1 may be formed with a trigger portion 23 for triggering the trigger point 71.

[0100] In some embodiments of the present invention, the first hinge seat 1 and the second hinge seat 2 adopt an ultra-thin design with a neat appearance and a compact structure. When the hinge assembly 100 is applied to the cooking utensil 200, less space is occupied.

[0101] Optionally, when the hinge assembly 100 is applied to the cooking utensil 200, the first hinge seat 1 and the second hinge seat 2 can be connected to the cooking utensil 200 by screw connection, which is convenient for installation and disassembly.

[0102] Combination Fig.10 According to some embodiments of the present invention, the first limiting portion 31 is formed at one end surface of the hollow pivot shaft 3 adjacent to the limiting member 4; for example, the first limiting portion 31 may be formed at Fig.10 At the right end face of the hollow pivot shaft 3 shown in the figure, the first limiting portion 31 can be arranged along the axial direction of the hollow pivot shaft 3 and protrude from the right end face of the hollow pivot shaft 3. The second limiting portion 41 is formed on one side of the limiting member 4 adjacent to the hollow pivot shaft 3, for example, the second limiting portion 41 can be formed on Fig.10 Thus, through the cooperation between the first limiting portion 31 and the second limiting portion 41, the second hinge seat 2 can be rotated relative to the first hinge seat 1 by the predetermined angle and then locked.

[0103] Here, the limiter 4 and the hollow pivot shaft 3 can be arranged along the axial direction, which is beneficial to reducing the overall thickness of the hinge assembly 100, facilitating the realization of an ultra-thin design, and also making the hinge assembly 100 simple in appearance, compact in structure, and small in space.

[0104] The hinge assembly 100 according to the embodiment of the present invention adopts a modular design concept and an ultra-thin structural design scheme, and has the advantages of thin thickness, small space occupation, and high integration. In addition, the hollow pivot shaft 3 is convenient for threading and assembly and disassembly.

[0105] Further, the first limiting portion 31 and the second limiting portion 41 are configured as a fan-shaped block. For example, the first limiting portion 31 can be configured as a fan-shaped block, and the second limiting portion 41 can be configured as a fan-shaped block. The fan-shaped block has two side surfaces arranged along the axis surrounding the hollow pivot shaft 3, and the hinge assembly 100 can be locked at a predetermined angle position by the corresponding cooperation of the two side surfaces on the first limiting portion 31 and the two side surfaces on the second limiting portion 41.

[0106] Here, the predetermined angle of rotation of the second hinge seat 2 relative to the first hinge seat 1 is adapted to the central angle of the sector block.

[0107] Further, the first limiting portion 31 and the second limiting portion 41 are respectively one or more sector-shaped blocks.

[0108] by Fig.10 Taking the first limiting part 31 as a fan-shaped block and the second limiting part 41 as a fan-shaped block as an example, when the limiting member 4 is in the locked position, the fan-shaped block of the first limiting part 31 fits with the fan-shaped block of the second limiting part 41, and the two limit each other. After the limiting, the hollow pivot shaft 3 will not rotate around the axis direction, thereby maintaining the relative angle between the first hinge seat 1 and the second hinge seat 2 connected to the hollow pivot shaft 3. Using the fan-shaped block as the limiting part not only has a simple structure and occupies a small space, but also the block is not easy to break and has a high structural strength.

[0109] When the number of sector blocks included in each limiting portion increases, the angle positions at which the first limiting portion 31 and the second limiting portion 41 can be limited to hover increase, thereby increasing the selection space of the hovering angle.

[0110] In some embodiments of the present invention, the first limiting portion 31 and the second limiting portion 41 may also adopt other structures, for example, a plug hole is provided on the side of one of them, and a plug column is formed on the side of the other one.

[0111] Reference Fig.10 According to some embodiments of the present invention, a first protrusion 42 is formed on the limiting member 4, and a first matching groove 111 matching the first protrusion 42 is formed on the inner side of the first hollow shaft 11, and the first protrusion 42 can be slidably fitted in the first matching groove 111.

The first matching groove 111 matches the first protrusion 42 , and the first protrusion 42 may be slidably fitted in the first matching groove 111 .

[0113] Furthermore, in the axial direction, the length of the first mating groove 111 is not less than the length of the first protrusion 42. Therefore, when the control limit member 4 is released from the locked state, the limit member 4 can be prevented from escaping from the first mating groove 111, which is beneficial to improving the reliability of the hinge assembly 100.

[0114] Combination Fig.10 , the inner side of the second hollow shaft 21 is provided with a second protrusion 211 extending in the axial direction of the second hollow shaft 21, and the hollow pivot shaft 3 is provided with a second matching groove 32 matching with the second protrusion 211. For example, the inner side of the second hollow shaft 21 may be provided with a second protrusion 211, the second protrusion 211 may extend in the axial direction of the second hollow shaft 21, and the hollow pivot shaft 3 may be provided with a second matching groove 32, the second matching groove 32 matches with the second protrusion 211, and the second protrusion 211 is matched in the second matching groove 32.

[0115] Furthermore, combined with Fig.10 The second limiting portion 41 may include an arc-shaped surface 411 , and the first protrusion 42 may be formed on an outer surface of the arc-shaped surface 411 .

[0116] In some specific embodiments of the present invention, the first protrusion 42 and the second protrusion 211 can be flat keys, and the first mating groove 111 and the second mating groove 32 can be flat key grooves. Thus, torque can be transmitted through the cooperation between the flat key and the flat key groove, so that the hinge assembly 100 can withstand the torque generated by the suspension of a large-mass connecting part, thereby improving the reliability of the hinge assembly 100.

[0117] like Fig.10 As shown, according to some embodiments of the present invention, a first mounting hole 43 is formed on the stopper 4, and the first mounting hole 43 can be formed on the inner side of the stopper 4, a second mounting hole 33 can be formed on the hollow pivot shaft 3, and the second mounting hole 33 can be formed on the inner side of the hollow pivot shaft 3, the second mounting hole 33 is coaxial with the first mounting hole 43, and the fastener 5 is suitable for sequentially passing through the first mounting hole 43 and the second mounting hole 33 to connect the stopper 4 with the hollow pivot shaft 3. Thus, a reliable connection between the stopper 4 and the hollow pivot shaft 3 can be achieved by sequentially passing the fastener 5 through the first mounting hole 43 and the second mounting hole 33.

[0118] Reference Fig.10According to some embodiments of the present invention, the fastener 5 may be a semi-thread screw 51 having a head 511, a fixing ring 44 may be formed on the stopper 4, and one end of the reset member 6 is connected to the head 511 of the semi-thread screw 51 and the other end is connected to the fixing ring 44. For example, one end of the reset member 6 may abut against the head 511 of the semi-thread screw 51, and the other end of the reset member 6 may abut against the end surface of the fixing ring 44, so that when the stopper 4 is moved outward, the hinge assembly 100 can be unlocked, and under the action of the reset member 6, the stopper 4 can be reset.

[0119] Here, a full-thread screw means that the entire screw has threads, and a half-thread screw means that half of the screw is threaded and the other half is plain.

[0120] According to some embodiments of the present invention, the hinge assembly 100 may further include: a damping member (not shown in the figure), at least the damping member is provided between the hollow pivot shaft 3 and the limiter 4, for example, the damping member may be provided between the hollow pivot shaft 3 and the limiter 4. Thus, it is possible to effectively prevent the structure at the second hinge seat 2 from falling and closing quickly, thereby avoiding injuring the user or causing damage to the hinge assembly 100, thereby facilitating improving the reliability and safety of the hinge assembly 100.

[0121] In some optional embodiments of the present invention, the damping member may also be provided between the first hinge seat 1 and the second hinge seat 2; or the damping member may be provided between the hollow pivot shaft 3 and the limiter 4, and between the first hinge seat 1 and the second hinge seat 2.

[0125] When the hinge assembly 100 is unfolded in the vertical state and within the range of 100 degrees of hinge rotation, the hinge assembly 100 can rotate freely, but at 100 degrees, the fan-shaped end surface of the first limiting portion 31 and the fan-shaped end surface of the second limiting portion 41 fit together to prevent the second hinge seat 2 from continuing to rotate backward; when the limiting member 4 is released (for example, pulled out to the right), the limiting structure fails, and the second hinge seat 2 can rotate backward beyond the 100-degree angle point and be fully unfolded and laid flat; in the final state, the second hinge seat 2 and the first hinge seat 1 are completely fit and stacked, and under the action of the gravity of the second hinge seat 2, the triggering portion 23 on the second hinge seat 2 triggers (for example, triggers in the horizontal direction) the micro switch installed in the first hinge seat 1 to achieve the switching of the oven state.

[0126] When the oven is restored from a fully open state (the second hinge seat 2 and the first hinge seat 1 are fully fitted and stacked) to a fully closed state (the second hinge seat 2 and the first hinge seat 1 are fully vertically unfolded), when the second cooking cavity 220 drives the second hinge seat 2 to rotate back past the 100-degree limit point, the reset member 6 will function, causing the second limit portion 41 of the limit member 4 to automatically slide axially to fit the first limit portion 31 of the hollow pivot shaft 3, and restore to the limit position; the limit member 4 functions again, and at this time the second cooking cavity 220 and the second hinge seat 2 can only be rotated backward to the 100-degree position; the limit member 4 needs to be released again (for example, moved to the right and pulled out) before it can be fully unfolded to the second cooking cavity 220 and the first cooking cavity 210 to be in a flat position.

[0127] According to some embodiments of the present invention, the cooking appliance 200 may be a foldable oven.

[0131] When working, the hinge assembly 100 needs to be pre-assembled and the corresponding wiring harness is assembled; the first hinge seat 1 is screwed to the first cooking cavity 210, and the second hinge seat 1 is screwed to the second cooking cavity 220; according to the working mode requirements, the limit member 4 can be locked or released (for example, the limit member 4 is pulled out or pressed down), and the full opening and closing mode or the partial opening and closing mode at a certain angle can be selected to work; in addition, according to actual needs, the sensing element 7 (for example, a micro switch or a position sensing device) is assembled to the hinge assembly 100; when the hinge assembly 100 is fully opened, the outer surfaces of the first hinge seat 1 and the second hinge seat 2 are almost in contact, the trigger part 23 presses the micro switch or triggers the position sensing device, and the cooking utensil 200 works in the second cooking mode; the first cooking cavity 210 and the second cooking cavity 220 are completely closed, in the partial opening and closing or hovering mode, the outer surfaces of the first hinge seat 1 and the second hinge seat 2 are separated, the micro switch returns to its position, or the sensing device returns to its position, and the cooking utensil 200 works in the second cooking mode.

[0132] According to the cooking utensil 200 of the embodiment of the present invention, the first cooking cavity 210 (for example, the lower cavity) and the second cooking cavity 220 (for example, the upper cavity) are connected together by a hinge assembly 100, and the hinge assembly 100 can be freely opened and closed from 0 to 180 degrees, or hover at a specific angle in the middle (for example, about 100 degrees); when the upper and lower cavities are combined, they form a closed cavity structure, becoming a traditional upper and lower tube oven, which can be used in corresponding baking scenarios; when the upper and lower cavities are separated and the hinge is opened 180 degrees and fully unfolded, they become two parallel multi-functional electric hot pots, which can perform related multi-functional pot operations such as cooking hot pot and frying steak.

[0133] The cooking utensil 200 according to the embodiment of the present invention is provided with a hinge assembly 100, wherein the first hinge seat 1 is connected to the first cooking cavity 210, and the second hinge seat 2 is connected to the second cooking cavity 220.

In addition, the hollow pivot shaft 3 is convenient for threading and assembly and disassembly, and the second matching groove 32 on the hollow pivot shaft 3 is tightly matched with the second protrusion 211 on the second hinge seat 2 (for example, the hinge upper seat). After assembly, the hollow pivot shaft 3 and the second hinge seat 2 become a whole. The end of the hollow pivot shaft 3 is provided with a first limiting portion 31 (for example, a step surface at the tail of the shaft) which is matched and assembled with the second limiting portion 41 on the limiting member 4 to prevent the limiting member 4 from sliding out, while ensuring that the limiting member 4 can have a certain amount of free displacement, so as to select not to The same working mode; a first protrusion 42 is provided on the limit member 4, and a first matching groove 111 is formed on the first hinge seat 1 (for example, the hinge lower seat), and the first protrusion 42 cooperates with the first matching groove 111, and can move axially to the left and right in a straight line, but cannot rotate; when the limit member 4 slides into the step surface at the tail end of the rotating shaft, when the hinge assembly 100 is opened to a predetermined angle, the fan-shaped surfaces of the first limit portion 31 and the second limit portion 41 fit each other to achieve the purpose of limited suspension; when the limit member 4 slides out of the step surface at the tail end of the rotating shaft, the limit member 4 is disengaged from the hollow pivot shaft 3, and can no longer prevent the hinge assembly 100 from continuing to rotate downward, and at this time the hollow pivot shaft 3 can be fully opened.
