Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic heating, in particular to a coil disk component and a cooking utensil. Background Art
[0002] Electromagnetic heating uses the magnetic field generated by the coil being energized to couple with the pot for heating. The position and area of the heat field generated in the cooking pot depends on the position of the coil winding, that is, the area where the heat field is formed will not exceed the coil area.
[0003] For conventional electromagnetic cookers (stoves), the surface supporting the pot is basically set to a flat shape, and the bottom of the pot is also generally flat; because the coil winding of a conventional electromagnetic heating coil disk is generally circular, but the circular coil winding has the magnetic field characteristics formed by its electromagnetic field, which will cause the central part of the coil winding and the outer peripheral part of the coil winding to be a hot field low temperature area. Therefore, the area heated by the electromagnetic heating coil disk on the pot is a ring-shaped heating field with a diameter smaller than the maximum diameter of the coil winding, and the heating area is concentrated in a smaller circular area (see Figures 1 to 5 As shown), there is a problem of uneven heating of the bottom of the pot.

[0048] Electromagnetic heating uses the magnetic field generated by the coil being energized to couple with the pot for heating. The location and area of the heat field generated in the cooking pot depends on the location of the coil winding, that is, the area where the heat field is formed will not exceed the coil area. For conventional induction cookers (ranges), the surface supporting the pot is basically set to a flat shape, and the bottom of the pot is also generally flat. The coil winding of a conventional electromagnetic heating coil disk is generally circular, but the circular coil winding has the magnetic field characteristics formed by its electromagnetic field, which will cause the center part of the coil winding and the outer peripheral part of the coil winding to also be a low temperature area of the heat field. Therefore, the area heated by the electromagnetic heating coil disk on the pot is an annular heating field with a diameter smaller than the maximum diameter of the coil winding, and the heating area is concentrated in a smaller annular area (see Figures 1 to 5 As shown), there is a problem of uneven heating of the bottom of the pot.
[0049] In order to solve the above problems, the utility model provides a coil disk assembly. Figure 1 to Figure 2 It is a schematic diagram of a circular coil winding and a corresponding thermal field generated in the prior art; Figure 3 A schematic diagram of the heat field generated by the covered area of a round-bottomed pot and a square-bottomed pot and a circular coil winding in the prior art; Figures 4 to 5 It is a schematic diagram of a square coil winding and the corresponding thermal field generated in the prior art; Figure 6 A plan view of an embodiment of a coil disk assembly provided by the utility model; Figure 7 A schematic plan view of another embodiment of the coil disk assembly provided by the utility model; Figure 8 for Figure 6 A schematic diagram of a first coil winding and a plurality of second coil windings; Fig. 9 for Figure 8 A schematic diagram of a thermal field generated by a first coil winding and a plurality of second coil windings;

[0051] See also Figures 6 to 9 The coil disk assembly 100 includes a mounting bracket 1, a first coil winding 2 and a plurality of second coil windings 3; the first coil winding 2 is arranged on the mounting bracket 1, and the first coil winding 2 is arranged in a ring shape; the plurality of second coil windings 3 are arranged at intervals on the mounting bracket 1, and are located inside the first coil winding 2, and each two adjacent second coil windings 3 are arranged so that when power is turned on, the current directions of the two second coil windings 3 are opposite.
[0052] It should be noted that the current directions of the adjacently arranged second coil windings 3 described in the present application are consistent and opposite, which both refer to the current flowing through the second coil windings 3 in a clockwise direction or a counterclockwise direction.
[0053] It can be understood that when the multiple second coil windings 3 are energized, the areas where the multiple second coil windings 3 are located will also generate multiple magnetic field areas accordingly. When the currents of two adjacent second coil windings 3 flow in different directions, the current directions of the two groups of coil segments close to each other are consistent. Then, in the area where the two are close to each other, the magnetic fields will be superimposed in this area, so that the magnetic field is enhanced, and the heating performance coupled with the cookware is enhanced.
[0054] It can also be understood that when two adjacent second coil windings 3 are energized, according to the attached Figure 8 As shown, when a clockwise current is passed through one of the second coil windings 3 and a counterclockwise current is passed through another adjacent second coil winding 3, the directions of the currents on the sides of the two adjacent second coil windings 3 that are close to each other can be controlled and achieved to be consistent; of course, when a counterclockwise current is passed through one of the second coil windings 3 and a clockwise current is passed through another adjacent second coil winding 3, the directions of the currents on the sides of the two adjacent second coil windings 3 that are close to each other can also be controlled to be consistent.
[0055] In the technical solution provided by the utility model, a first coil winding 2 and a plurality of second coil windings 3 are arranged on the mounting bracket 1, the first coil winding 2 is arranged in a ring shape, and the plurality of second coil windings 3 are located in the inner periphery of the first coil winding 2. Since the inner circle diameter of the first coil winding 2 is relatively large, the reverse direction of the current of the wires arranged relatively on the inner side will not affect the size of the overall thermal field area of the first coil winding 2; each two adjacent second coil windings 3 are arranged so that when energized, the current directions of the two second coil windings 3 are reversed, so that the magnetic fields of the two adjacent second coil windings 3 in the area close to each other will be superimposed and enhanced, so that the outer side of each second coil winding 3 also has a strong magnetic field, so that the thermal field area formed by coupling with the cookware will not be weakened, and overall, the area where the plurality of second coil windings 3 are located can all cover a strong magnetic field, so that the coil disk assembly 100 can generate a strong heating field in the area where the first coil winding 2 and the plurality of second coil windings 3 are located, avoiding the low thermal field temperature in the middle area of the first coil winding 2, so as to solve the problem of uneven heating in conventional electromagnetic coil disks.
[0056] See also Figure 10 to Figure 11 In some embodiments, the plurality of second coil windings 3 are arranged in a matrix. It is understandable that the size of each second coil winding 3 is set fairly, so the size of the area covered, the magnetic field strength generated after power-on, etc. are all consistent. In this way, in the matrix arrangement, the magnetic field interaction of different second coil windings 3 can compensate each other, reduce the deviation of the overall magnetic field, increase the coverage area of the magnetic field, help balance the magnetic field generated by each coil winding, and make the overall magnetic field more uniform. At the same time, by arranging a plurality of second coil windings 3 in a matrix, the gradient change of the magnetic field can be reduced, so that the change of the magnetic field in space is more gentle, so as to reduce the non-uniformity of the magnetic field and improve the stability and uniformity of the magnetic field.
[0057] Specifically in one embodiment, please refer to Figures 8 to 10 There are four second coil windings 3, two in each column and two in each row. Each second coil winding 3 can be conveniently installed on the mounting bracket 1. This solution can achieve 4+4 heating areas, a total of 8 heating areas, and can achieve a larger heating area for the cooker in a small-sized coil disk assembly 100, a more uniform heating effect, and can also adapt to round and square inner pots.
[0058] In another embodiment, see Fig.11 The second coil windings 3 are provided with nine, three in each column and three in each row, so that a more uniform heating effect can be achieved, but the cost will be higher and the manufacturing process will be more difficult. The number of the second coil windings 3 can be set according to different design requirements.
[0059] It should be noted that when the multiple second coil windings 3 are arranged in a matrix, each two adjacent second coil windings 3 refer to two adjacent second coil windings 3 in the same row; or refer to two adjacent second coil windings 3 in the same column; and the two second coil windings 3 located on the diagonal line are not the two adjacent second coil windings 3 referred to in this application, and the current directions of the two second coil windings 3 located on the diagonal line are set consistently.
[0060] In other embodiments, the plurality of second coil windings 3 are arranged at intervals along the circumference of the mounting bracket 1. In this way, the uniformity of the generated magnetic field is also improved by mutual superposition, covering and balancing.
[0061] Specifically, in order to realize that when power is applied to each two adjacent second coil windings 3, the current directions of the two second coil windings 3 are opposite, in one embodiment, the plurality of second coil windings 3 are arranged in series, and the winding directions of each two adjacent second coil windings 3 are arranged opposite. In this way, when power is applied, the current directions of each two adjacent second coil windings 3 can be opposite through the winding direction, without the need to set up an overly redundant electric control device to change the current direction.
[0062] Of course, in order to prevent the failure of one of the second coil windings 3 from affecting the other second coil windings 3, the multiple second coil windings 3 can also be arranged in parallel, and the direction of current inflow can be controlled through electronic control elements and circuit design to achieve the reversal of the current direction.
[0063] In the prior art, please refer to Figure 3 Generally, the coil disk is set to be circular, making it more suitable for round-bottomed pots. However, when it comes to square pots, it is difficult to generate a magnetic field to couple with the four corners of the pot, thus affecting the user's cooking experience.
[0064] In this embodiment, the first coil winding 2 is arranged in a square ring shape. It should be noted that the square ring shape refers to a square, a rectangle, or a square or rectangle with chamfered corners. Since square frying pans are commonly used in addition to round-bottomed frying pans, the first coil winding 2 can cover the space inside the induction cooker as much as possible, and the square heating area formed can be adapted to square-shaped cookware.
[0065] In some embodiments, see Figure 6 to Figure 7 The second coil winding 3 is arranged in a polygonal or circular shape. Specifically, the second coil winding 3 can be a triangle, a quadrilateral, a rhombus, a pentagon, a hexagon, etc., and can also be a polygon with chamfers. When the chamfers are large, they can be regarded as a circle.
[0066] In one specific embodiment, see Figure 6 , the first coil winding 2 is arranged in a square ring shape; each second coil winding 3 is arranged in a square shape. In this way, when the plurality of second coil windings 3 are arranged in an array, two adjacent second coil windings 3 are arranged in parallel between opposite sides, so that the directions of the generated magnetic fields are also parallel, thereby reducing electromagnetic interference between coils, avoiding unnecessary electromagnetic coupling and interference caused by the coils crossing or staggered, and affecting the performance and stability of the circuit. At the same time, it can reduce energy loss, improve the efficiency of electromagnetic energy transmission, help reduce the energy consumption of the circuit, and optimize the performance of the electromagnetic device.
[0067] In this example, see Figure 8 The side length of the first coil winding 2 is set to A, wherein 170 mm ≤ A ≤ 260 mm. The size of the first coil winding 2 is constrained within this range, so that it can be adapted to the size of commonly used pots.
[0068] When the coil disk assembly 100 is applied to an induction cooker, the induction cooker is generally configured in a square shape. In order to enable the coil disk assembly 100 to cover a larger area, in this embodiment, the mounting bracket 1 is configured in a quasi-square shape. In this way, the mounting bracket 1 can be adapted to the induction cooker housing, and the first coil winding 2 can be matched to form a quasi-square shape when wound on the mounting bracket 1.
[0069] In this embodiment, the mounting bracket 1 is arranged flat, so that the first coil winding 2 and the plurality of second coil windings 3 can be arranged flat on one side of the mounting bracket 1, so that the working distance coupled with the cookware is consistent and the heating is more uniform.
[0070] In one embodiment, see Fig.12, the mounting bracket 1 is provided with a first winding structure 4, the first winding structure 4 includes a first winding portion 41 and a second winding portion 42, the first winding portion 41 is provided at one side of the mounting bracket 1, and a first winding groove with a notch facing the peripheral side of the mounting bracket 1 is defined between the first winding portion 41 and the mounting bracket 1; the second winding portion 42 is provided at one side of the mounting bracket 1, and is located at the inner periphery of the first winding portion 41, and a second winding groove with a notch facing the peripheral side of the mounting bracket 1 is defined between the second winding portion 42 and the mounting bracket 1; wherein the first coil winding 2 is limited to the first winding groove, and the second coil winding 3 is limited to the second winding groove. In this way, on the mounting bracket 1, the first coil winding 2 can be limited in the first winding groove by side winding, and a plurality of the second coil windings 3 can also be wound in the second winding groove by side winding. By side winding, it is easier to achieve a lower cost production using fewer coil windings.
[0071] In another embodiment, see Fig.13 , the mounting bracket 1 is provided with a second winding structure 5, the second winding structure 5 includes a third winding groove 5a and a fourth winding groove 5b formed on one side of the mounting bracket 1, the fourth winding groove 5b is arranged inside the third winding groove 5a; wherein the first coil winding 2 is correspondingly arranged in the plurality of third winding grooves 5a, and the second coil winding 3 is correspondingly arranged in the plurality of fourth winding grooves 5b. In this way, the first coil winding 2 and the plurality of the second coil windings 3 can be wound on the mounting bracket 1 in a sparse winding manner, so that it is easier to adjust the multi-turn coil and it is also easier to meet the multi-ring solution.
[0072] It should be noted that in applications requiring high current and low voltage, the sparse winding method can provide higher current capacity and lower voltage. In addition, when sparsely wound, the coil winding is more compact and the current flows more densely through the winding, thus generating a higher magnetic field density and a stronger heating effect.
[0073] In applications that require high voltage and low current, side winding can provide higher voltage output. In the side winding method, the winding distribution of the coil is relatively scattered, the current distribution is relatively uniform, and the heating effect is relatively uniform.
[0074] The sparse winding method is often used in electromagnetic heating in situations where rapid heating and high temperature are required, and it can provide a larger power output. The side winding method is often used in electromagnetic heating in situations where more uniform heating and controlled heating temperature are required, and it can provide a more stable heating effect. In summary, the choice of sparse winding and side winding in electromagnetic heating coil disks depends on the specific heating requirements, including the required power output, heating speed, heating uniformity and other factors. Choosing the appropriate winding method according to the actual situation can better meet the heating requirements and obtain the ideal heating effect.
[0075] See also Fig.14 The present invention further provides a cooking utensil 200, which includes the above-mentioned cooking device. Since the cooking utensil 200 includes the above-mentioned cooking device, the specific structure of the cooking device refers to the above-mentioned embodiment. Since the cooking device of the cooking utensil 200 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
[0076] In order to conveniently control the current direction of the first coil winding 2 and the plurality of second coil windings 3, in this embodiment, the cooking appliance 200 further includes a control device, which is electrically connected to the first coil winding 2 and the plurality of second coil windings 3, and is used to control the operation of the first coil winding 2 and the plurality of second coil windings 3. In this way, the control device can realize electric control, and in scenarios such as switching heating modes for different pots, the control button can be operated, and the control device automatically switches the current direction of the power supply to the first coil winding 2 and each of the second coil windings 3 according to the control instruction.
[0077] Specifically, the cooking utensil 200 includes an induction cooker or an induction cooker. When the cooking utensil 200 is set as an induction cooker, one heating device can be provided; when the cooking utensil 200 is set as an induction cooker, multiple heating devices can be provided to form multi-head heating. Of course, the setting form and application scenario of the heating device are not limited to the above examples, and can be specifically designed according to actual conditions, and the embodiments of this specification do not limit this.
