In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

In view of the above, the present invention provides a coil base, which is applied to a coil panel applied to an electromagnetic cooking appliance, and it can be understood that the specific representation form of the electromagnetic cooking appliance is not limited, and may be an electromagnetic oven, an electric cooker, a food processor, a bread maker, a cooking machine, or the like. Wherein, the electromagnetic cooking utensil generally also comprises a pot body; the coil panel comprises a coil winding, a coil panel seat and a magnet structure. Referring to fig. 1 to 5, embodiments of a coil disc seat according to the present invention are shown in the drawings. Since the main utility model of the present invention is the improvement of the coil bobbin 200, the coil bobbin 200 will be mainly described with reference to the specific drawings.

Referring to fig. 1 to 3, the coil base 200 provided by the present invention includes a base body 200a and a supporting structure, wherein the supporting structure is disposed on the base body 200a, the supporting structure defines a plurality of winding slots with lateral openings, at least two winding slots are sequentially disposed in a direction of the supporting structure approaching to and departing from the base body 200a, and each winding slot is used for winding and forming a coil winding 100; wherein at least a portion of the bracket structure is configured for mounting the magnet structure 400.

In the technical scheme provided by the utility model, the bracket structure forms the winding slot with a lateral opening, so that the coil is easier to wind and form in the winding slot, and a tighter coil winding 100 is obtained; the two winding slots are stacked in the direction close to and far away from the tray body 200a, which is beneficial to forming stronger magnetic field and thermal field on the limited tray body 200 a; the partial support structure directly constitutes the mounting structure of the magnet structure 400, so that additional arrangement of the magnet support is avoided, and the injection molding or assembling process of the magnet support is simplified, thereby contributing to improvement of the processing efficiency of the coil panel 10.

In this design, the tray body 200a has an inner side and an outer side which are oppositely arranged, and the inner side of the tray body 200a is used for being close to the pot body 1a of the electromagnetic cooking appliance 1 so as to conduct heat with the pot body 1 a.

The support structure may be disposed on the inner side and/or the outer side of the tray body 200a according to actual needs, but for easy understanding, the support structure is disposed on the outer side surface of the tray body 200a in the following embodiments. Based on this, the support structure is close to and far away from the direction of the seat body 200a, namely, the inner and outer directions of the position.

It can be understood that, when the supporting structure is disposed on the outer side of the seat body 200a, the coil winding 100 can be wound on the outer side of the seat body 200 a. Because the coil winding 100 can generate a high-frequency changing magnetic field after alternating current is supplied, heat is generated to the metal pot body 1a in the changing magnetic field through an eddy current effect, and the coil winding 100 and the pot body 1a are spaced by arranging the tray seat body 200a, so that the coil winding 100 and the pot body 1a can be protected.

The bracket structure defines the winding slot that is open laterally. It is understood that the lateral direction may be a side toward the middle of the tray body 200a, and may also be a side toward the periphery of the tray body 200 a. However, in order to facilitate the winding of the coil winding 100, in the following embodiments, the notch of the winding slot faces the periphery of the seat body 200 a. So set up, the wire can be from the periphery of disk seat body 200a to the middle part of disk seat body 200a in proper order the wire winding, presents for comparatively inseparable and covers the great many circles of wire windings of area, shaping coil winding 100, has simple structure, convenient operation's characteristics.

When the support structure is provided as one, at least a part of the support structure can define at least two winding slots, and the at least two winding slots are stacked in a direction close to and away from the seat body 200a, that is, in an inward-outward direction, so that at least two layers of the coil winding 100 can be wound and molded at least a part of the seat body 200 a. The coil windings 100, which are arranged in multiple layers, can enhance the magnetic field and the thermal field strength of the coil disk 10 at the corresponding position.

Of course, the number of the winding slots at the same position needs to be set within a proper range, which is not preferable to be set too much, and the coil winding 100 with multiple layers has a limited effect of enhancing the magnetic field and the thermal field, and is easy to increase the cost and the structural complexity. Therefore, in the present embodiment, the coil winding 100 may be provided in two layers at least at a portion.

In view of the above, the tray body 200a may be disposed in a flat shape, that is, the tray body 200a may be substantially in a disk shape, and the support structure is disposed on an outer side surface of the tray body 200 a.

Alternatively, the tray body 200a is configured as a concave shape as in the present embodiment, and has a tray bottom 210 and a tray side 220 formed by bending and extending from the periphery of the tray bottom 210. The tray base 210 may be disposed in a flat shape or an arc shape. It can be understood that when the dish seat body 200a is in a concave arrangement, the shape of the pan body 1a can be adapted, specifically, when the pan body 1a is placed in the concave position of the dish seat body 200a, the dish seat bottom 210 corresponds to the bottom of the pan body 1a, and the dish seat side 220 corresponds to the side of the pan body 1a, so that the coil panel 10 can heat the bottom and the side of the pan body 1a, the range of the heated area of the pan body 1a is enlarged, and the heating effect of the food to be cooked is improved.

Further, by setting the number and the positions of the coil windings of the support structure, one or more coil windings 100 may be formed on the outer side surface of the seat body 200a, wherein when a plurality of coil windings 100 are provided, the plurality of coil windings 100 may be arranged in concentric arcs or may be arranged in different regions. Specifically, in an embodiment, the coil winding 100 may include a first winding 110 and a second winding 120, wherein the first winding 110 is disposed on the seat bottom 210 and the second winding 120 is disposed on the seat side 220.

Referring to fig. 2 to 5, in an embodiment, the supporting structure includes a first support 310 and a second support 320, wherein the first support 310 is disposed at the tray bottom 210, the first support 310 defines a first winding slot 311a, and the first winding slot 311a is used for winding the first winding 110; and/or the second bracket 320 is disposed on the tray side 220, the second bracket 320 defines a second winding slot 321a, and the second winding slot 321a is used for the second winding 120 to wind.

The support structure is divided into the first support 310 and the second support 320, so that the winding and forming processes of the first winding 110 and the second winding 120 are independent of each other, a magnetic field and a thermal field can be formed at the tray bottom 210 and the tray side 220 respectively, and the uniform and comprehensive heating of the pot body 1a is facilitated.

It is understood that, in the above, at least a part of the first winding 110 and/or the second winding 120 may be disposed in a double layer. Specifically, in one embodiment, the first winding slots 311a are provided in plurality, and at least two first winding slots 311a are stacked in a direction approaching and departing from the seat body 200 a; and/or, the second winding groove 321a is provided with a plurality of second winding grooves, and at least two second winding grooves 321a are stacked in a direction approaching to and departing from the seat body 200 a. Since the material in the pot body 1a may not be much needed for heating the side portion 220 of the seat because the cooking amount does not reach the preset amount, but at least the bottom portion 210 of the seat is much needed for heating, it is optional to provide only a plurality of first winding grooves 311a, at least two of which are stacked in a direction close to and away from the seat body 200a, so as to enhance the magnetic field and the thermal field of the main region, simplify the structure and reduce the cost.

Further, the first bracket 310 may be formed on the tray bottom 210 in a block shape, and at this time, the first winding groove 311a is opened on one side of the first bracket 310 facing the periphery of the tray body 200 a.

Alternatively, referring to fig. 3 to 5, in an embodiment, the first bracket 310 includes a first arm 311, and the first arm 311 extends from a middle portion of the tray bottom 210 to a periphery of the tray bottom 210 to define a first winding slot 311a for the first winding 110 to wind around with the tray bottom 210.

Specifically, one end of the first arm 311 is connected to a position close to the middle of the tray bottom 210, and extends toward the periphery of the tray bottom 210 after protruding in a direction away from the tray body 200a so as to be spaced from the tray bottom 210, and the spaced position constitutes the first winding groove 311 a.

The shape of the first arm 311 is adapted to the shape of the tray bottom 210 at the position, so that the groove width of the first winding groove 311a is substantially consistent along the groove depth direction, thereby generating a uniform pressing effect on the first winding 110 when the first winding 110 is wound.

Referring to fig. 3 to 5, in an embodiment, the first bracket 310 further includes at least one dividing portion 330, and the dividing portion 330 is disposed between the first arm 311 and the tray bottom 210 and extends parallel to the first arm 311 to divide at least two first winding grooves 311a between the first arm 311 and the tray bottom 210.

Specifically, the line segment 330 extends from the middle of the tray bottom 210 toward the periphery of the tray bottom 210. Specifically, the dividing portion 330 has a front end located near the middle of the tray bottom 210 and a rear end located at a position rearward from the center of the tray bottom 210, and the front end of the dividing portion 330 may be directly connected to the tray bottom 210 or directly connected to the first arm 311.

The front end of the line segment 330 may be substantially flush with the front end of the first arm 311, or connected to the front side of the front end of the first arm 311, or connected between both ends of the first arm 311. The rear end of the line segment 330 may be substantially flush with the rear end of the first arm 311, or may be connected to the front side of the rear end of the first arm 311, or between both ends of the first arm 311.

In addition, the widths of the at least two first winding grooves 311a separated by the dividing portion 330 may be at least partially different, but in order to facilitate winding, in an embodiment, the widths of the at least two first winding grooves 311a separated by the dividing portion 330 are substantially the same, so that the two first windings 110 wound separately are uniformly and uniformly maintained.

It is understood that the dividing portion 330 can be detachably connected to the first arm 311 or the base bottom 210, so as to adjust the number of the first winding slots 311a to be separated and the width of each of the first winding slots 311a to be separated according to actual requirements. Alternatively, as in this embodiment, the dividing portion 330 may be integrally provided with the first arm 311. The integral injection molding of the dividing portion 330 and the first arm 311 contributes to the reduction of the number of steps for assembling the dividing portion 330 and the simplification of the entire structure of the coil bobbin 200.

It should be noted that, when the first arm 311 is provided in plural, the dividing portion 330 may be provided at least one of the first arms 311, so that at least part of the first winding 110 is provided in multiple layers.

In addition, if the first winding 110 formed by winding the branching portion 330 is a single winding body 111, one or more single winding bodies 111 may be disposed in each first arm 311; specifically, in one embodiment, the plurality of the line-dividing portions 330 are spaced along the length direction of the first arm 311. When defined as described above: the direction from the middle to the periphery of the tray bottom 210 is from front to back, and the length direction of the first arm 311 is also from front to back. One end of the line-dividing part 330 is connected to the first arm 311, and the other end extends rearward. That is, the winding units 111 on the same first arm 311 are provided in plurality, and the winding units 111 are arranged in plurality at intervals along the front-back direction, so that at least part of the first winding 110 is arranged in a partitioned manner.

Next, in an embodiment, the first support arm 311 may be continuously disposed in one along the circumferential direction of the tray bottom 210, at this time, the first support arm 311 is substantially disc-shaped, and the formed first winding slot 311a is substantially ring-shaped; of course, the first support arm 311 may be provided in a plurality of discontinuous shapes along the circumferential direction of the tray bottom 210, which is helpful for saving materials and has a certain heat dissipation effect.

In addition, when the first arm 311 is provided in plurality, the bracket structure further includes a winding protrusion 313 protruding from the middle of the base 210, and the plurality of first arms 311 are integrally provided with the winding protrusion 313; the winding convex part 313 can enhance the injection molding strength of the first support arms 311.

Further, in an embodiment, a pre-groove 314 is formed on a side of the winding protrusion 313 facing away from the base bottom 210, and the pre-groove 314 is used for installing functional components of the coil panel 10, for example, when the coil panel 10 further includes a temperature measuring device 500, the temperature measuring device 500 can be installed in the pre-groove 314, which contributes to the compact structure.

Further, in an embodiment, a side of the winding protrusion 313 facing away from the base portion 210 is provided with a reserved groove 314, the reserved groove 314 is provided with a wire routing portion 315, the wire routing portion 315 may be a slot formed at a bottom of the reserved groove 314 or at a side of the groove, and the slot communicates with the reserved groove 314 to provide a sufficient space for wiring and wire clamping of the functional component mounted in the reserved groove 314. In addition, according to actual needs, the preformed groove 314 can also penetrate through the tray body 220a for installation

Similarly to the above, the second arm 321 may be continuously arranged in one along the circumferential direction of the tray side portion 220, in this case, the second arm 321 is substantially disc-shaped, and the formed second winding groove 321a is substantially ring-shaped; of course, the second arm 321 may be provided in a plurality of discontinuous shapes along the circumferential direction of the tray side portion 220, which is helpful for saving materials and has a certain heat dissipation effect.

In addition, in an embodiment, the second arm 321 is provided in a block shape, and a side of the second arm 321 facing away from the tray side 220 is provided with a groove 322. It can be understood that the second arm 321 disposed in a block shape can provide sufficient strength, but is formed with a thicker thickness, which easily affects the uniformity of the magnetic field and the thermal field of the second winding 120, so that a groove 322 may be further provided on a side of the second arm 321 opposite to the tray side 220, and the provision of the groove 322 also facilitates the injection molding of the second arm 321 disposed in a block shape, and improves the molding quality of the second arm 321 during the injection molding process.

Alternatively, in an embodiment, the second arm 321 is disposed in a plate shape, and a side of the second arm 321 opposite to the seat side 220 is protruded with a rib 323. It can be understood that the second arm 321 with a plate shape is easier to be injection molded, but has insufficient strength, and therefore, a rib 323 can be further protruded on a side of the second arm 321 opposite to the seat side 220, and the rib 323 is used to increase the strength of the second arm 321. The reinforcing ribs 323 may be arranged to extend in a direction close to and away from the tray bottom portion 210, and the reinforcing ribs 323 may be provided in one or more, wherein when the reinforcing ribs 323 are provided in plural, the plural reinforcing ribs 323 are arranged side by side.

Next, in one embodiment, the second winding slot 321a has a first slot wall far away from the seat side 220; the first groove wall slopes gradually away from the seat side 220 in a direction adjacent to its notch. The inclined first slot wall can guide the wire entering the second winding slot 321a, so that the second winding 120 is easier to wind and form; in addition, the first slot wall is obliquely arranged near the slot opening, so that the slot width of the second winding slot 321a at the position for pressing the second winding 120 is not affected to be consistent, and the limiting effect of the second winding slot 321a on the second winding 120 is still ensured.

In one embodiment, the supporting structure and the seat body 200a may be integrally provided. Specifically, the disk seat body 200a and the support structure are directly and integrally injection-molded, and compared with a scheme in which the support structure and the disk seat body 200a are separately arranged, particularly when the number of the support structures is large, the assembly operation process of the support structure on the disk seat body 200a can be reduced, thereby contributing to improving the processing efficiency of the coil disk 101.

At least part of the support structure is used for mounting the magnet structure 400. It is understood that the magnet structure 400 may be mounted on at least a portion of the support structure, or when the support structure is provided with a plurality of support units, or includes a plurality of support units, at least a portion of the support structure or the support units may be used for mounting the magnet structure 400. By the magnetic convergence of the magnet structure 400, the magnetic field formed by the coil winding 100 can be strengthened and homogenized, so that a strong thermal field can be generated for the pot body 1 a.

Specifically, when the support structure includes the first support 310 and the second support 320 as described above, both the first support 310 and the second support 320 may be used for mounting the magnet structure 400, and in the present embodiment, the first support 310 and the second support 320 may alternatively be used for mounting the magnet structure 400 due to the arrangement of the first support 310 and the second support 320, which makes the first winding 110 and the second winding 120 sufficiently form a strong magnetic field and a strong thermal field.

It can be understood that when the magnet structure 400 is disposed on the tray base portion 210, the magnetic concentration effect of the magnet structure 400 makes the tray base portion 210 have a stronger magnetic field, so that the first winding 110 has a stronger thermal field corresponding to the bottom wall of the pot body 1a, and when the magnet structure 400 is disposed on the tray base side portion 220, the magnetic concentration effect of the magnet structure 400 makes the tray base side portion 220 have a stronger magnetic field, so that the second winding 120 has a stronger thermal field corresponding to the side wall of the pot body 1a, thereby realizing that only the side wall of the pot body 1a or the bottom wall of the pot body 1a has a stronger thermal field effect to satisfy different cooking functions.

Specifically, in one embodiment, a mounting groove 312 is disposed on a side of the first arm 311 facing away from the tray bottom 210, and the mounting groove 312 is used for mounting the magnet structure 400. The magnet structure 400 is generally disposed in an elongated shape in a direction toward and away from the middle of the seat body 200a, and the mounting groove 312 is adapted to the shape of the magnet structure 400. The magnet structure 400 may be mounted in the mounting groove 312 in various ways, such as by adhesive, snap, etc.

In addition, the present invention further provides a coil panel 10, as described above, the coil panel 10 includes the coil winding 100, the magnet structure 400, and the coil panel base 200 described above.
