Description

[0001] The utility model relates to the technical field of electromagnetic coil discs, in particular to a mounting bracket and a cooking utensil. Background Art

The traditional coil disk is to wind the coil winding in the winding groove of the coil mounting bracket.

[0030] Electromagnetic heating uses the magnetic field generated by the coil after it is energized to couple with the pot for heating. The traditional coil disk is to wind the coil winding in the winding groove of the coil mounting bracket. The position and area of the heat field generated in the cooking pot depends on the position of the coil winding. When the area size required to form the heat field of different types of cooking utensils is different, the size of the corresponding electromagnetic heating coil disk will be different, and the size requirements of the electromagnetic coil disk in different application scenarios are also different. Because the coil winding of the conventional electromagnetic heating coil disk is generally circular, the area heated by the electromagnetic heating coil disk on the pot is annular. For different types of pots, such as square pots, in order to ensure that the corners of the square pot are in the heat field, the electromagnetic coil disk needs to be set to a larger diameter. At present, different types of electromagnetic coil disks need to be produced for application scenarios with different requirements, and the versatility of electromagnetic coil disks is poor.
[0031] In order to solve the above problems, the utility model provides a mounting bracket. Figure 1An exploded schematic diagram of an embodiment of a mounting bracket provided by the utility model; Figure 2 A schematic diagram of another embodiment of the mounting bracket provided by the utility model; Figure 3 for Figure 2 A schematic diagram of a mounting bracket in which a first coil winding and a second coil winding are wound; Figure 4 The exploded schematic diagram of an embodiment of the coil disk assembly provided by the utility model.
[0032] See also Figure 1 to Figure 2 The mounting bracket 100 includes a first bracket 1 and a second bracket 2 arranged on the periphery of the first bracket 1, the second bracket 2 is arranged in a square ring shape, the first bracket 1 and the second bracket 2 are detachably connected, and a winding structure for winding the coil winding is provided on the mounting bracket 100, and the winding structure includes a first winding portion 11 and a second winding portion 21, the first bracket 1 is provided with the first winding portion 11 for winding the first coil winding 3, and the second bracket 2 is provided with the second winding portion 21 for winding the second coil winding 4.
[0033] It should be noted that when a large heating area is required, the first bracket 1 and the second bracket 2 can be combined, and the first coil winding 3 and the second coil winding 4 can both work. When dual-stage control is required, the first coil winding 3 and the second coil winding 4 can be set in parallel, and the adjustment of different power gears can be achieved through the electronic control device; when the first bracket 1 with the first coil winding 3 or the second bracket 2 with the second coil winding 4 is damaged or fails, the inner circle coil disk or the outer circle coil disk can be easily disassembled and replaced for easy maintenance.
[0034] When there is no need to implement dual-stage control, the first coil winding 3 and the second coil winding 4 only need to be connected in series, and even a wire can be continued to be wound on the second winding part 21 after the first winding part 11 is wound, so as to achieve a series effect.
[0035] It is understandable that when only a small diameter electromagnetic coil disk is needed in certain scenarios, or when multiple small coil disk units need to be set up to form a multi-head heating cooking utensil, only the first bracket 1 with the first coil winding 3 wound around it can be used as the coil disk.
[0036] In the technical solution provided by the utility model, the mounting bracket 100 includes a first bracket 1 and a second bracket 2 arranged on the periphery of the first bracket 1. The first bracket 1 and the second bracket 2 are detachably connected. When it is necessary to adapt to a large-sized cooking utensil, the first bracket 1 and the second bracket 2 can be assembled together. The first coil winding 3 and the second coil winding 4 can work at the same time to produce a larger heating area. When it is necessary to adapt to a small-sized cooking utensil, only the first bracket 1 wound with the first coil winding 3 can be used alone. At the same time, the mounting bracket 100 The second bracket 2 is arranged in a square ring shape, so the second coil winding 4 wound on the second bracket 2 generates a square thermal field accordingly. Under the condition that the length and width of the cooking utensils are equal, the area of the square is larger than the area of the circle. When a square cookware is used, the bottom of the square cookware can be heated evenly, and when a round cookware is used, the bottom of the round cookware can also be heated evenly. For cooking utensils of different sizes and types, and for different types of cookware, the first bracket 1 and the second bracket 2 can be disassembled and assembled to adapt to different usage scenarios, so as to solve the problem of poor versatility of existing electromagnetic coil disks.
[0037] In this embodiment, the first bracket 1 and the second bracket 2 are clamped or bonded. When the first bracket 1 and the second bracket 2 need to be clamped, a clamping portion and a buckling portion can be provided between the first bracket 1 and the second bracket 2, or an interference fit can be formed between the first bracket 1 and the second bracket 2. Of course, other possible connection forms can also be used, which can be determined according to actual conditions, and the embodiments of this specification do not limit this.
[0038] Furthermore, in this embodiment, the first bracket 1 is arranged in a quasi-square shape. It should be noted that the quasi-square ring refers to a square, a rectangle, or a square or rectangle with chamfered corners. When a smaller square frying pan is needed, the first coil winding 3 can cover the space inside the induction cooker as much as possible, and the square heating area formed can be adapted to square-shaped pots.
[0039] At the same time, the first bracket 1 is arranged in a quasi-square shape, so the hollow part in the middle of the second bracket 2 is also quasi-square, and the inner circle and the outer circle of the second bracket 2 are of the same shape, which is convenient for molding. Each turn of the first coil winding 3 and the second coil winding 4 can be wound in a quasi-square shape, so that the first coil winding 3 can be naturally connected when transitioning to the second coil winding 4, avoiding the blank area of the laying causing a heating blind spot.
[0040] For further information, see Figure 1 to Figure 2In this embodiment, the first winding portion 11 includes a plurality of first winding grooves formed on one side of the first bracket 1, and the first coil winding 3 can be wound on the first 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; the second winding portion 21 is arranged on one side of the second bracket 2, and a second winding groove with a notch facing the side of the mounting bracket 100 is defined between the first winding portion 11 and the first bracket 1, and the second coil winding 4 is wound in the second winding groove in a side winding manner. The side winding method makes it easier to achieve lower cost production using fewer coil windings.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] In this way, a sparse winding method is adopted on the first bracket 1, so that the thermal field generated in the heating area of the middle inner ring of the electromagnetic coil disk is more uniform, and a side winding method is adopted on the first bracket 1, so that the magnetic field of the outer ring of the electromagnetic coil disk can be more concentrated and stronger. In this way, while enhancing the magnetic field of the outer ring, it also ensures that the magnetic field of the inner ring is not overly concentrated, thereby improving the overall uniformity.
[0045] Specifically, when dual-stage control is required, please refer to Figure 1In the first embodiment, the first bracket 1 is provided with a first wire inlet (not shown) and a first wire outlet a, the first wire inlet is connected to the first winding groove located in the innermost circle, and the wire outlet is connected to the first winding groove located in the outermost circle; the second bracket 2 is provided with a second wire inlet b and a second wire outlet, the second wire inlet b and the second wire outlet are both connected to the second winding groove; in this way, the first coil winding 3 and the second coil winding 4 are respectively wound in the corresponding winding groove, and the parallel connection and control of the two coil windings are realized by the circuit of the external electric control device.
[0046] Specifically, when dual-stage control is not required, refer to Figures 2 to 4 In the second embodiment, the first bracket 1 is provided with a first wire inlet (not shown) and a first wire outlet a, the first wire inlet is connected to the first winding groove located in the innermost circle, and the wire outlet is connected to the first winding groove located in the outermost circle; the second bracket 2 is provided with a wire inlet channel c, a second wire inlet b and a second wire outlet, the wire inlet channel c is connected to the first wire inlet, the second wire inlet b is opposite to and connected to the first wire outlet a, and the second wire outlet is connected to the second winding groove. In this way, when winding, after winding in the first winding groove on the first bracket 1, the wire can be passed from the first wire outlet a to the second wire inlet b to complete the winding in the second winding groove. In this way, the first coil winding 3 and the second coil winding 4 can be connected in series.
[0047] In this embodiment, the side length of the second bracket 2 is set to A, wherein 170 mm ≤ A ≤ 260 mm. The size of the second coil winding 4 is restricted within this range, so as to be compatible with the size of commonly used pots.
[0048] The utility model also provides a coil disk assembly, which includes the above-mentioned mounting bracket 100. Since the coil disk assembly includes the mounting bracket 100, the specific structure of the mounting bracket 100 refers to the above-mentioned embodiment. Since the mounting bracket 100 of the coil disk assembly 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 repeated here one by one.
[0049] Specifically, in this embodiment, the coil disk assembly further includes a coil winding, and the coil winding includes a first coil winding 3 and a second coil winding 4, the first coil winding 3 is wound in the plurality of first winding slots, and the second coil winding 4 is wound in the second winding slot; the first coil winding 3 and the second coil winding 4 are arranged in parallel so as to be independently controlled. In this way, when it is necessary to keep food warm or cook at low temperature, low-power heating is achieved by controlling the current or frequency of one coil winding; when rapid heating or high-temperature cooking is required, high-power heating is achieved by heating two coil windings at the same time, or increasing the current or frequency of the two coil windings, so as to switch different control modes according to the user's selection or set program, thereby achieving the adjustment of different power gears.
[0050] The utility model also provides a cooking utensil, which includes the above-mentioned coil disk assembly. Since the cooking utensil includes the coil disk assembly, the specific structure of the coil disk assembly refers to the above-mentioned embodiment. Since the coil disk assembly of the cooking utensil 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 repeated here one by one.
[0051] In order to conveniently control the current magnitude or operating frequency of the first coil winding 3 and the second coil winding 4, in this embodiment, the cooking appliance further includes a control device, which is electrically connected to the first coil winding 3 and the second coil winding 4, and is used to control the operation of the first coil winding 3 and the second coil winding 4. 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 magnitude or operating frequency of the power supply to the first coil winding 3 and the second coil winding 4 according to the control instruction.
[0052] When the cooking utensil is configured as an induction cooker, one coil disk assembly may be provided; when the cooking utensil is configured as an induction cooker, a plurality of coil disk assemblies may be provided to form multi-head heating.
[0053] It is understandable that the coil disk assembly can select only the first bracket 1 with the first coil winding 3 as the heating unit according to actual conditions; or only the first bracket 1 with the first coil winding 3 and the second bracket 2 with the second coil winding 4 as the heating units; or for the convenience of arrangement, multiple first brackets 1 with the first coil winding 3 can be selected as part of the heating units, and multiple first brackets 1 with the first coil winding 3 and the second bracket 2 with the second coil winding 4 can be selected as the other part of the heating units.
