Technical Field
[0001] This utility model relates to the field of induction cooker technology, specifically to a stable folding induction cooker. Background Technology
[0002] Induction cookers typically use electromagnetic induction to heat cookware in a non-contact manner, offering advantages such as high thermal efficiency, rapid heating, and ease of cleaning. Foldable induction cookers, on the other hand, usually consist of two or more rotatable sections. When not in use, they can be folded for storage to reduce space requirements, and unfolded to form a complete heating surface when needed, balancing practicality and portability.
[0003] Traditional folding induction cookers typically achieve their folding function through a hinge plate and a pivot. However, when unfolded, the hinge area of a traditional induction cooker lacks sufficient support strength, resulting in low structural stability. Furthermore, repeated folding and use can easily lead to loosening, wobbling, or even breakage of the hinge, affecting safety and lifespan. Utility Model Content
[0004] The purpose of this invention is to provide a stable folding induction cooker. By setting up a first support plate and a second support plate, the folding flexibility is ensured while improving the structural rigidity and overall stability in the unfolded state.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stable folding induction cooker, including a first cooker body and a second cooker body, with a connecting box extending in a left-right direction between the first cooker body and the second cooker body. The first cooker body has a first receiving groove, and the second cooker body has a second receiving groove. One end of the connecting box extends into the first receiving groove and is rotatably connected to the side wall of the first receiving groove, and the other end of the connecting box extends into the second receiving groove and is rotatably connected to the side wall of the second receiving groove. The bottom of the first receiving groove has a plurality of first support plates extending toward the opening direction of the first receiving groove, and the bottom of the second receiving groove has a plurality of second support plates extending toward the opening direction of the second receiving groove. The plurality of first support plates are spaced apart along the length direction of the connecting box to support one end of the connecting box; the plurality of second support plates are spaced apart along the length direction of the connecting box to support the other end of the connecting box.
[0006] As a further optimization of this utility model, both the first support plate and the second support plate have guide recesses on their upper parts. The connecting box has a first mating part at one end near the first furnace body. The first mating part can slide and engage with the side wall of the guide recess on the first support plate when the first furnace body and the connecting box rotate relative to each other. The connecting box has a second mating part at one end near the second furnace body. The second mating part can slide and engage with the side wall of the guide recess on the second support plate when the second furnace body and the connecting box rotate relative to each other.
[0007] As a further optimization of this utility model, the guide recess is arc-shaped.
[0008] As a further optimization of this utility model, the connecting box has a receiving cavity for accommodating cables. The connecting box has a first rotating shaft. The side wall of the first receiving groove has a first shaft hole that mates with the first rotating shaft. The first shaft hole communicates with the inner cavity of the first furnace body. The first rotating shaft has a first through hole that extends through it along its axial direction. One end of the first through hole communicates with the receiving cavity, and the other end of the first through hole communicates with the inner cavity of the first furnace body via the first shaft hole. The connecting box has a second rotating shaft. The side wall of the second receiving groove has a second shaft hole that mates with the second rotating shaft. The second shaft hole communicates with the inner cavity of the second furnace body. The second rotating shaft has a second through hole that extends through it along its axial direction. One end of the second through hole communicates with the receiving cavity, and the other end of the second through hole communicates with the inner cavity of the second furnace body via the second shaft hole.
[0009] As a further optimization of this utility model, the connecting box includes a base and a top cover, and the receiving cavity is formed by the base and the top cover. The base is provided with a guide for guiding the cable, and the top cover is provided with a locking member that can press the cable onto the guide to limit the cable position.
[0010] As a further optimization of this utility model, the upper cover is provided with a positioning boss, the positioning boss is provided with a first screw hole, the base is provided with a positioning groove that matches the positioning boss, and the bottom of the positioning groove is provided with a second screw hole corresponding to the first screw hole.
[0011] As a further optimization of this utility model, the first rotating shaft, the second rotating shaft, and the connecting box are integrally formed.
[0012] Compared with the prior art, the present invention has the following advantages: by setting multiple first support plates and second support plates at intervals along the length direction of the connecting box at the bottom of the first and second receiving grooves, the two ends of the connecting box can obtain continuous bottom support in the entire length direction, effectively preventing the connecting box from deforming due to local stress or suspension, thereby enhancing the structural stability in the unfolded state, reducing the stress intensity of the rotating connection point, extending the service life of the hinge mechanism, and improving the reliability of long-term use.

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0018] like Figures 1 to 4 As shown, this utility model discloses a stable folding induction cooker, including a first cooker body 1 and a second cooker body 2. A connecting box 3 extending in the left-right direction is provided between the first cooker body 1 and the second cooker body 2. The first cooker body 1 has a first receiving groove 11, and the second cooker body 2 has a second receiving groove 21. One end of the connecting box 3 extends into the first receiving groove 11 and is rotatably connected to the side wall of the first receiving groove 11, and the other end of the connecting box 3 extends into the second receiving groove 21 and is rotatably connected to the side wall of the second receiving groove 21. The bottom of the first receiving groove 11 has a plurality of first support plates 41 extending toward the opening direction of the first receiving groove 11, and the bottom of the second receiving groove 21 has a plurality of second support plates 42 extending toward the opening direction of the second receiving groove 21. The plurality of first support plates 41 are spaced apart along the length direction of the connecting box 3 to support one end of the connecting box 3; the plurality of second support plates 42 are spaced apart along the length direction of the connecting box 3 to support the other end of the connecting box 3.
[0019] In this embodiment, both the first furnace body 1 and the second furnace body 2 include a bottom shell and a top shell, which together form an inner cavity containing conventional induction cooker components such as an electromagnetic coil, a cooling fan, and a control circuit board. When in use, the two furnace bodies unfold side-by-side in the front-to-back direction, forming a continuous heating area. When stored, they can be folded relative to each other, reducing the overall space occupied. The connecting box 3 has a long, rectangular shell structure. The interior of the connecting box 3 can be a cavity to accommodate flexible circuits such as leads and signal lines connecting the two furnace bodies, preventing exposed wiring from affecting the folding action or safety. The first furnace body 1 has a first receiving groove 11 at its end closest to the second furnace body 2. This receiving groove 11 is an inwardly recessed cavity structure with its opening facing the second furnace body 2. The second furnace body 2 has a second receiving groove 21 at its end closest to the first furnace body 1, with its opening facing the first furnace body 1. When the two furnace bodies are unfolded, the first receiving groove 11 and the second receiving groove 21 are positioned opposite each other, together forming a space to accommodate both ends of the connecting box 3. One end of the connecting box 3 extends into the first receiving groove 11 and is rotatably connected to the two side walls of the first receiving groove 11 via a pivot, pin, or bearing. Similarly, the other end of the connecting box 3 extends into the second receiving groove 21 and is rotatably connected to the two side walls of the second receiving groove 21. Thus, with the connecting box 3 as a fixed pivot, the first furnace body 1 and the second furnace body 2 can rotate relative to each other around the two ends of the connecting box 3, achieving folding and unfolding actions.
[0020] Multiple first support plates 41 are integrally formed or fixedly installed on the bottom of the first receiving groove 11, and the first support plates 41 extend upward from the bottom toward the opening of the first receiving groove 11, so as to contact or abut against the lower surface of one end of the connecting box 3 when the first furnace body 1 is unfolded into place. The multiple first support plates 41 are evenly distributed along the length of the connecting box 3, covering the main stress area of one end of the connecting box 3. Similarly, multiple second support plates 42 are provided at the bottom of the second receiving groove 21, and the second support plates 42 extend upward from the bottom toward the opening of the second receiving groove 21 and are distributed along the length of the connecting box 3, so as to support the lower surface of the other end of the connecting box 3 in the unfolded state. When the induction cooker is in the unfolded use state, the two ends of the connecting box 3 are supported from below by multiple sets of support plates, forming a multi-point distributed rigid support, effectively avoiding the downward deflection or twisting deformation of the middle of the connecting box 3 caused by the cantilever of the two ends of the pivot alone, ensuring that the two furnace body panels remain coplanar and flat, and improving heating stability and structural reliability.
[0021] Compared to using a continuous support base plate or solid support block, using multiple spaced support plates allows the connecting box 3 to contact the support structure only in a limited number of local areas, reducing the actual sliding contact area and thus effectively reducing the total frictional resistance. This makes the folding action lighter and smoother, while the gaps between the support plates can serve as temporary storage space or discharge channels for dust and debris, preventing foreign objects from accumulating on the sliding interface and forming abrasive wear, thereby improving the stability of folding.
[0022] By setting multiple first support plates 41 and second support plates 42 at intervals along the length of the connecting box 3 at the bottom of the first receiving groove 11 and the second receiving groove 21, the two ends of the connecting box 3 are provided with continuous bottom support along the entire length, which effectively prevents the connecting box 3 from deforming due to local stress or suspension, thereby enhancing the structural stability in the unfolded state, reducing the stress intensity of the rotating connection point, extending the service life of the hinge mechanism, and improving the reliability of long-term use.
[0023] Both the first support plate 41 and the second support plate 42 have guide recesses 43 on their upper parts. The connecting box 3 has a first mating part 31 at one end near the first furnace body 1. The first mating part 31 can slide and engage with the side wall of the guide recess 43 on the first support plate 41 when the first furnace body 1 and the connecting box 3 rotate relative to each other. The connecting box 3 has a second mating part 32 at one end near the second furnace body 2. The second mating part 32 can slide and engage with the side wall of the guide recess 43 on the second support plate 42 when the second furnace body 2 and the connecting box 3 rotate relative to each other.
[0024] The opening of the guide recess 43 faces the direction of the connecting box 3. Multiple first support plates 41 and second support plates 42 have their guide recesses 43 aligned horizontally to form a guide channel. A first mating part 31 is located on the outer periphery of the connecting box 3 near the first furnace body 1, and its shape matches the inner contour of the guide recess 43. Second mating parts 32 are symmetrically located on the outer periphery of the connecting box 3 near the second furnace body 2, and are used to mate with the guide recesses 43 on the second support plates 42. During folding or unfolding, the guide recesses 43 guide the end of the connecting box 3 along a predetermined trajectory, preventing swaying or jamming.
[0025] The guide recess 43 is arc-shaped.
[0026] In this embodiment, the inner contour of the guide recess 43 is a continuous arc curve, and the first mating part 31 and the second mating part 32 are arc protrusions that match the inner contour of the guide recess 43, so that when the first mating part 31 and the second mating part 32 rotate, their surfaces can slide tightly against the arc sidewall of the guide recess 43, thereby improving stability.
[0027] The connecting box 3 has a receiving cavity 33 for accommodating cables. The connecting box 3 has a first rotating shaft 34. The side wall of the first receiving groove 11 has a first shaft hole 12 that mates with the first rotating shaft 34. The first shaft hole 12 is connected to the inner cavity of the first furnace body 1. The first rotating shaft 34 has a first through hole 341 that extends through it along its axial direction. One end of the first through hole 341 is connected to the receiving cavity 33, and the other end of the first through hole 341 is connected to the inner cavity of the first furnace body 1 via the first shaft hole 12. The connecting box 3 has a second rotating shaft 35. The side wall of the second receiving groove 21 has a second shaft hole 22 that mates with the second rotating shaft 35. The second shaft hole 22 is connected to the inner cavity of the second furnace body 2. The second rotating shaft 35 has a second through hole 351 that extends through it along its axial direction. One end of the second through hole 351 is connected to the receiving cavity 33, and the other end of the second through hole 351 is connected to the inner cavity of the second furnace body 2 via the second shaft hole 22.
[0028] The receiving cavity is a hollow cavity extending along the length of the connecting box 3, used to accommodate the flexible cable connecting the first furnace body 1 and the second furnace body 2. In this embodiment, the first rotating shaft 34 is a cylindrical boss extending axially outward from the left end of the connecting box 3, integrally formed with the connecting box 3. A first through hole 341 is opened through the axial center of the first rotating shaft 34, forming a hollow channel. One end of the first through hole 341 communicates with the receiving cavity 33 inside the connecting box 3, and the other end opens onto the end face of the first rotating shaft 34. The first rotating shaft 34 is rotatably inserted into the first shaft hole 12 on the side wall of the first receiving groove 11. The first shaft hole 12 is a through hole, and its inner side communicates with the inner cavity of the first furnace body 1. The second rotating shaft 35 is a cylindrical boss extending axially outward from the right end of the connecting box 3, with a structure symmetrical to the first rotating shaft 34. A second through hole 351 is opened axially along the second rotating shaft 35, with one end communicating with the receiving cavity 33 and the other end opening onto the end face of the second rotating shaft 35. The second rotating shaft 35 is inserted into the second shaft hole 22 on the side wall of the second receiving groove 21, and the second shaft hole 22 communicates with the inner cavity of the second furnace body 2. The wiring channel formed by the aforementioned structure allows the cable connecting the first furnace body 1 and the second furnace body 2 to be hidden inside the connecting box 3, so that it is not pulled, worn or exposed during the folding process, and does not affect the smoothness of rotation.
[0029] The connecting box 3 includes a base 36 and a top cover 37. The receiving cavity 33 is formed by the base 36 and the top cover 37. The base 36 is provided with a guide 38 for guiding the cable. The top cover 37 is provided with a locking member 39 that can press the cable onto the guide 38 to limit the cable.
[0030] The connecting box 3 adopts a split design, including a base 36 and a top cover 37, which are detachably and fixedly connected by means of buckles, screws, etc. When the top cover 37 is closed on the base 36, the two together form a closed receiving cavity 33 for accommodating the flexible cable connecting the first furnace body 1 and the second furnace body 2. A guide 38 is provided on the inner side of the base 36, which can be a rib extending along the length of the connecting box, an arc groove, or multiple spaced limiting posts, used to guide the cable to be laid along a predetermined path and prevent it from moving or stacking randomly in the receiving cavity. A locking member 39 is provided on the inner side of the top cover 37, which can be a downwardly extending elastic pressure plate, a hook, or a protrusion. When the top cover 37 is installed in place, the locking member 39 presses precisely on top of the cable and abuts against the guide 38, thereby clamping and limiting the cable between the guide 38 and the locking member 39, effectively preventing the cable from shifting, tangling, or being subjected to localized force due to shaking or vibration during folding.
[0031] The upper cover 37 is provided with a positioning boss 371, and the positioning boss 371 is provided with a first screw hole 372. The base 36 is provided with a positioning groove 361 that matches the positioning boss 371. The bottom of the positioning groove 361 is provided with a second screw hole 362 that corresponds to the first screw hole 372.
[0032] The positioning boss 371 is a columnar or block-shaped structure protruding downward from the inner surface of the upper cover 37. A first screw hole 372 is provided on its top or inside. The positioning groove 361 is a recessed cavity formed by the downward indentation of the upper surface of the base 36. Its shape and size match the positioning boss 371, so that when the upper cover 37 is placed on the base 36, the positioning boss 371 can be precisely embedded in the positioning groove 361, achieving precise horizontal alignment of the upper and lower housings and preventing assembly misalignment. A second screw hole 362 is provided at the bottom of the positioning groove 361. When the positioning boss 371 is fully inserted into the positioning groove 361, the first screw hole 372 and the second screw hole 362 are coaxially aligned. At this time, screws can be screwed in from the outside of the connecting box 3 and pass through the first screw hole 372 and the second screw hole 362, thereby locking the upper cover 37 onto the base 36.
[0033] The first rotating shaft 34, the second rotating shaft 35 and the connecting box 3 are integrally formed, which makes the connection between the first rotating shaft 34, the second rotating shaft 35 and the connecting box 3 firm and reliable. At the same time, the positional relationship between the axis of the rotating shaft and the receiving cavity 33 is highly accurate and consistent, which is conducive to accurate matching with the shaft hole on the furnace body.
