Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a coil plate and cooking equipment. Background Art

[0002] Electric stoves can achieve electromagnetic resonant heating and infrared heating effects through only one set of windings, making them suitable for both metal and non-metallic pots. However, if electromagnetic and infrared radiation work at the same time, electromagnetic heating will cause local overheating in the middle of the pot.

[0003] In this regard, in the related art, the number of windings is reduced or the winding spacing is increased in the electromagnetic heating concentrated area, thereby reducing the heating energy in the heating concentrated area and making the overall heating uniform.

[0004] However, the reduction in the number of turns and the increase in the spacing will lead to a decrease in the coil's ability to heat non-metallic cookware, resulting in the technical problem of uneven heating. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, a first aspect of the present invention provides a coil disk.

[0007] A second aspect of the present invention provides a cooking device.

[0008] In view of this, the first aspect of the present invention provides a coil disk, which includes: a supporting component; a winding, the winding is arranged on the supporting component, the winding is coiled to form a coil, and the coil can generate heat radiation and an electromagnetic field when energized; wherein the winding is spirally coiled on the supporting component, and in the extension direction, the winding includes at least one first section and at least one second section, and the winding directions of the first section and the second section are opposite.

[0009] The present application defines a coil disk, which can heat a cooking utensil, thereby cooking food through the high-temperature cooking utensil. The coil disk includes a supporting component, which is used to protect, position and support other working structures on the coil disk.

[0010] The coil disk also includes a winding, which is fixed on a supporting component and spirally wound into a coil on the supporting component. The wound coil can not only generate an electromagnetic field above the coil disk for heating magnetic cooking utensils, but can also heat the non-magnetic cooking utensils above it through infrared heat radiation generated by itself after power is turned on. Specifically, the electromagnetic heating mode and the infrared heating mode can be switched by adjusting the power supply parameters of the winding.

[0011] On this basis, the winding is divided into a first section and a second section in the extension direction. The first section and the second section are connected in series in the extension direction of the winding, and the first section and the second section are distinguished by the direction of winding.

[0012] Specifically, the first section is wound along a first rotation direction, and the second section is wound along a second rotation direction, the first rotation direction and the second rotation direction being opposite. For example, when the coil is viewed from above, the first section is wound counterclockwise, and the second section is wound clockwise.

[0013] Because the first and second segments are wound in different directions, the electromagnetic fields generated by them above the coil do not align in the same direction. The opposing electromagnetic fields cancel each other out in the overlapping area, reducing the electromagnetic heating intensity in that area and, therefore, minimizing the likelihood of localized overheating in the cooking appliance when both the electromagnetic and infrared heating functions are activated simultaneously. Specifically, the coil's winding density, shape, and size all affect the location of the heat concentration area. This technical solution does not impose rigid restrictions on the specific distribution of the first and second segments; it is sufficient to mitigate the heat concentration issue by partially canceling out the electromagnetic fields.

[0014] On this basis, the infrared thermal radiation heating capacity of the coil is not affected by the winding rotation direction of the winding. The first section and the second section with different rotation directions designed in this application can maintain the number of turns and spacing of the coil, thereby maintaining the uniformity of the thermal radiation heating of the coil to non-metallic cooking utensils on the basis of improving the problem of electromagnetic heat concentration of the coil, avoiding the appearance of obvious cold areas on non-metallic cooking utensils, and thus solving the technical problem of poor heating uniformity in related technologies, and achieving the technical effect of improving the heating uniformity and reliability of the coil disk.

[0015] Specifically, the raw material of the winding is a high-temperature resistant metal material, and the linear expansion coefficient of the high-temperature resistant metal material is low to avoid high-temperature damage or high-temperature deformation of the coil. Specifically, the coil can be made of copper alloy or iron alloy.

[0016] In addition, the coil disk provided by the present invention may also have the following additional technical features:

[0017] In some technical solutions of the present invention, specifically, in the radial direction of the coil, the first segments and the second segments are alternately arranged.

[0018] In this technical solution, first and second segments are alternately arranged in the radial direction of the coil. Adjacent first and second segments cancel each other out at their junctions, reducing electromagnetic field strength to prevent overheating of the cooking appliance at the corresponding locations in this region.

[0019] On this basis, by alternately arranging multiple first sections and second sections, multiple spaced magnetic field overlapping areas can be formed in the radial direction of the coil, thereby improving the uniformity of the low magnetic field area and further improving the heating uniformity of the coil disk.

[0020] In some technical solutions of the present invention, specifically, the winding includes two first sections and one second section; in the radial direction of the coil, the second section is located between the two first sections.

[0021] In this technical solution, the winding includes two first sections and one second section. In the radial direction of the coil, one first section is located on the inner turn of the coil, the other first section is located on the outer turn of the coil, and the second section is located between the two first sections.

[0022] Specifically, when the coil is wound with uniform density, electromagnetic heating often results in concentrated heat in the coil's middle layers. By placing the second segment between the inner and outer first segments, the electromagnetic field strength in this concentrated heat area can be reduced through reverse cancellation, alleviating the coil's heat concentration and improving heating uniformity across the coil disk.

[0023] In some technical solutions of the present invention, specifically, the number of winding turns of the second section is greater than or equal to 1.

[0024] In this technical solution, the number of winding turns of the second section must be greater than or equal to 1. By setting a second coil layer with a number of turns greater than or equal to 1, it can be ensured that the reverse electromagnetic field generated by the second winding is sufficient to offset the electromagnetic field generated by the first section in the heat concentration area, thereby reducing the electromagnetic field intensity in the heat concentration area, avoiding the appearance of obvious cold areas on non-metallic cooking utensils, and thus solving the technical problem of poor heating uniformity in related technologies, and achieving the technical effect of improving the heating uniformity and reliability of the coil disk.

[0025] Specifically, when the second section is located between the two first sections, the number of turns of the second section is less than or equal to half of the total number of turns of the coil, so as to reasonably distribute the positive and negative electromagnetic fields on the coil and ensure heating uniformity of the coil disk.

[0026] In some technical solutions of the present invention, specifically, there are multiple second segments, and the multiple second segments are distributed in the circumferential direction of the coil.

[0027] In this technical solution, the plurality of second segments are distributed in the circumferential direction of the coil.

[0028] For example, the three second sections may be evenly divided between the inner and outer first sections along the circumferential direction.

[0029] Among them, the number of turns of the second section and the circumferential winding angle of each second section can be adjusted according to needs, so that the coil can freely adjust the uniformity of thermal radiation heating and electromagnetic heating, thereby improving the heating effect of the cooking appliance.

[0030] In some technical solutions of the present invention, specifically, the coil is circular, polygonal or racetrack-shaped.

[0031] In this technical solution, the winding shape of the coil includes a circle, and the circular coil can form a corresponding circular heating area, which is suitable for heating a round-bottomed pot and makes it convenient for users to align the cooking utensil with the heating area.

[0032] The winding shape of the coil also includes polygons, such as rectangular coils. The rectangular coil has the advantage of a large heating area and can be adapted to large-sized cooking utensils or special-shaped cooking utensils, thereby broadening the application scenarios of the coil disk.

[0033] The winding shape of the coil also includes a runway shape. The heating area formed by the runway-shaped coil can heat two cooking utensils at the same time, so that the two coils originally distributed on the left and right can be merged together, thereby reducing the structural complexity of the coil disk.

[0034] In some technical solutions of the present invention, specifically, the coil disk further includes: a magnetic strip, which is provided on the supporting component and located between the supporting component and the coil.

[0035] In this technical solution, the coil disk further includes a magnetic strip, which is provided on the supporting component and is located between the supporting component and the coil.

[0036] By setting up magnetic strips, the distribution of the electromagnetic field on the side of the coil facing away from the cooking utensil can be changed, so that the electromagnetic field generated by the coil can be concentrated on the side where the cooking utensil is located, thereby centrally heating the cooking utensil and achieving the technical effect of improving electromagnetic heating efficiency and electromagnetic heating energy efficiency.

[0037] In some technical solutions of the present invention, specifically, the length direction of the magnetic strip is consistent with the radial direction of the coil; there are multiple magnetic strips, and the multiple magnetic strips are evenly distributed in the circumferential direction of the coil.

[0038] In this technical solution, the length direction of the magnetic strip is consistent with the radial direction of the coil. By arranging the magnetic strip along the radial direction of the coil, the deflection effect of the electromagnetic field can be enhanced to concentrate the electromagnetic field on the cooking utensil on the other side.

[0039] On this basis, there are multiple magnetic strips, and the multiple magnetic strips are evenly distributed in the circumferential direction of the coil. By setting up multiple evenly distributed magnetic strips, the magnetic field deflection blind spot on the side of the coil facing away from the cooking utensil can be avoided, thereby further improving the electromagnetic heating effect of the coil disk.

[0040] In some technical solutions of the present invention, specifically, the coil disk further includes: a heat insulation layer, which is provided on the supporting component and is located between the supporting component and the coil.

[0041] In this technical solution, a thermal insulation layer is installed on the side of the support component facing the coil. This layer prevents the heat generated by the coil from being transferred to the support component. This layer not only prevents the high-temperature coil from burning the support component, but also concentrates the heat generated by the coil on the side where the cooking utensils are located. This improves the safety and reliability of the coil disk and enhances the energy efficiency of infrared heating.

[0042] Specifically, the thermal insulation layer has a temperature resistance of at least 400°C. The material of the thermal insulation layer can be a mixture of white carbon black and moissanite, or can be flexible vacuum silicon insulation cotton.

[0043] A second aspect of the present invention provides a cooking device, which includes: a main body; and a coil disk such as that in any of the above technical solutions, which is arranged on the main body.

[0044] This technical solution proposes a cooking device equipped with the coil disk described in any of the above-mentioned technical solutions. Therefore, this cooking device possesses the advantages and can achieve the technical effects achieved by the coil disk described in any of the above-mentioned technical solutions. To avoid repetition, further details will be omitted here.

[0045] On this basis, the cooking device also includes a body, which is the main frame structure of the cooking device. The body is used to position, support and protect other working structures on the cooking device. The coil disk can be set inside the body, and the coil disk can also be embedded on the top of the body to heat the cooking utensils placed on the cooking device through the coil disk.

[0046] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0060] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0061] Refer to the following Figures 1 to 9 Coil pans and cooking devices according to some embodiments of the present invention are described.

[0062] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, one embodiment of the present invention provides a coil disk 100, which includes: a support component 110; a winding 120, which is provided on the support component 110 and is wound to form a coil. When the coil is energized, it can generate heat radiation and an electromagnetic field. The winding 120 is spirally wound on the heat-insulating component, and in the extension direction, the winding 120 includes at least one first segment 122 and at least one second segment 124, and the winding directions of the first segment 122 and the second segment 124 are opposite.

[0063] Figure 1 In FIG, arrow a shows the transfer direction of heat radiation.

[0064] Figure 2 , arrow b shows the radial direction of the coil.

[0065] Figure 4 In FIG. 1 , arrow c shows the direction of the electromagnetic field generated by the first segment 122 , and arrow d shows the direction of the electromagnetic field generated by the second segment 124 .

[0066] The present application defines a coil disk 100 that can heat a cooking utensil 300, thereby cooking food using the high-temperature cooking utensil 300. The coil disk 100 includes a support component 110 for protecting, positioning, and supporting other working structures on the coil disk 100.

[0067] The coil disk 100 also includes a winding 120, which is fixed on the support component 110 and spirally wound into a coil on the support component 110. The wound coil can not only generate an electromagnetic field above the coil disk 100 for heating the magnetic cooking utensil 300, but can also heat the non-magnetic cooking utensil 300 above through infrared heat radiation generated by itself after power is turned on. Specifically, the electromagnetic heating mode and the infrared heating mode can be switched by adjusting the power supply parameters of the winding 120.

[0068] On this basis, the winding 120 is divided into a first section 122 and a second section 124 in the extension direction. The first section 122 and the second section 124 are connected in series in the extension direction of the winding 120, and the first section 122 and the second section 124 are distinguished by the direction of winding.

[0069] Specifically, the first section 122 is wound along a first rotation direction, and the second section 124 is wound along a second rotation direction, the first rotation direction and the second rotation direction being opposite. For example, when looking down at the coil, the first section 122 is wound counterclockwise, and the second section 124 is wound clockwise.

[0070] Because the first and second segments 122, 124 are wound in different directions, the electromagnetic fields generated by the first and second segments 122, 124 above the coils are directed in opposite directions. These opposing electromagnetic fields cancel each other out in the overlapping region, thereby reducing the electromagnetic heating intensity in the overlapping region and, therefore, minimizing the likelihood of localized overheating in the cooking appliance 300 when both the electromagnetic and infrared heating functions are activated simultaneously. Specifically, the coil winding density, coil shape, and coil size all affect the location of the heat concentration region. Therefore, this embodiment does not impose a rigid limit on the specific distribution of the first and second segments 122, 124; suffice it to alleviate the heat concentration problem by partially canceling out the electromagnetic fields.

[0071] On this basis, the infrared thermal radiation heating capacity of the coil is not affected by the winding rotation direction of the winding 120. The first section 122 and the second section 124 with different rotation directions designed in this application can maintain the number of turns and spacing of the coil, thereby maintaining the uniformity of the thermal radiation heating of the coil to the non-metallic cooking utensil 300 on the basis of improving the problem of electromagnetic heat concentration of the coil, avoiding the occurrence of obvious cold areas on the non-metallic cooking utensil 300, and thus solving the technical problem of poor heating uniformity existing in the related technology, and achieving the technical effect of improving the heating uniformity and reliability of the coil disk 100.

[0072] Specifically, the raw material of the winding 120 is a high-temperature resistant metal material with a low linear expansion coefficient to avoid high-temperature damage or deformation of the coil. Specifically, the coil can be made of copper alloy or iron alloy.

[0073] like Figure 2 and Figure 7 As shown, in some embodiments of the present invention, specifically, in the radial direction of the coil, the first segments 122 and the second segments 124 are alternately arranged.

[0074] Figure 7 In FIG, arrow e shows the circumferential direction of the coil.

[0075] In this embodiment, the first segments 122 and the second segments 124 are alternately arranged in the radial direction of the coil. Adjacent first segments 122 and second segments 124 reduce the electromagnetic field strength by counteracting each other at the junction area, thereby preventing overheating of the cooking appliance 300 at the corresponding location in this area.

[0076] On this basis, by alternately arranging multiple first segments 122 and second segments 124 , multiple spaced magnetic field overlapping regions can be formed in the radial direction of the coil, thereby improving the uniformity of the low magnetic field region and further improving the heating uniformity of the coil disk 100 .

[0077] like Figure 2As shown, in some embodiments of the present invention, specifically, the winding 120 includes two first segments 122 and one second segment 124 ; in the radial direction of the coil, the second segment 124 is located between the two first segments 122 .

[0078] In this embodiment, the winding 120 includes two first segments 122 and one second segment 124. In the radial direction of the coil, one first segment 122 is located on the inner turn of the coil, the other first segment 122 is located on the outer turn of the coil, and the second segment 124 is located between the two first segments 122.

[0079] Specifically, when the coil is wound with uniform density, electromagnetic heating often results in concentrated heat areas in the coil's middle layers. By positioning the second segment 124 between the inner and outer first segments 122, the electromagnetic field strength in these concentrated heat areas can be reduced through reverse cancellation, thereby alleviating the coil's heat concentration and improving heating uniformity across the coil disk 100.

[0080] In some embodiments of the present invention, specifically, the number of winding turns of the second section 124 is greater than or equal to one.

[0081] In this embodiment, the number of winding turns of the second section 124 needs to be greater than or equal to 1. By setting a second coil layer with a number of turns greater than or equal to 1, it can be ensured that the reverse electromagnetic field generated by the second winding 120 is sufficient to offset the electromagnetic field generated by the first section 122 in the heat concentration area, thereby reducing the electromagnetic field intensity in the heat concentration area, avoiding the appearance of obvious cold areas on the non-metallic cooking utensil 300, and thus solving the technical problem of poor heating uniformity existing in the related technology, and achieving the technical effect of improving the heating uniformity and reliability of the coil disk 100.

[0082] Specifically, when the second section 124 is located between the two first sections 122 , the number of turns of the second section 124 is less than or equal to half of the total number of turns of the coil, so as to reasonably distribute the positive and negative electromagnetic fields on the coil and ensure heating uniformity of the coil disk 100 .

[0083] like Figure 2 As shown, in one embodiment of the present application, the number of winding turns of the second section 124 is 1.

[0084] In another embodiment of the present application, the number of winding turns of the second section 124 is greater than or equal to 2, specifically as follows Figure 7 As shown, the number of winding turns can be selected as 2.

[0085] like Figure 7 As shown, in some embodiments of the present invention, specifically, there are multiple second segments 124 , and the multiple second segments 124 are distributed in the circumferential direction of the coil.

[0086] In this embodiment, the plurality of second segments 124 are distributed in the circumferential direction of the coil.

[0087] For example, the three second sections 124 may be evenly divided between the inner and outer first sections 122 along the circumferential direction.

[0088] Among them, the number of turns of the second section 124 and the circumferential winding angle of each second section 124 can be adjusted according to needs, so that the coil can freely adjust the uniformity of thermal radiation heating and electromagnetic heating, thereby improving the heating effect of the cooking appliance 300.

[0089] like Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, specifically, the coil is circular, polygonal or racetrack-shaped.

[0090] In this embodiment, the winding shape of the coil includes a circle, and the circular coil can form a corresponding circular heating area, which is suitable for heating a round-bottomed pot and makes it convenient for the user to align the cooking utensil 300 with the heating area.

[0091] The winding shape of the coil also includes polygons, such as rectangular coils. The rectangular coil has the advantage of a large heating area and can be adapted to large-sized cooking utensils 300 or irregular-shaped cooking utensils 300, thereby broadening the application scenarios of the coil disk 100.

[0092] The winding shape of the coil also includes a racetrack shape. The heating area formed by the racetrack-shaped coil can heat two cooking utensils 300 at the same time, so that the two coils originally distributed on the left and right can be merged together, thereby reducing the structural complexity of the coil disk 100.

[0093] like Figure 8 As shown, in some embodiments of the present invention, specifically, the coil disk 100 further includes: a magnetic strip 130, which is provided on the support component 110 and located between the support component 110 and the coil.

[0094] In this embodiment, the coil disk 100 further includes a magnetic strip 130 . The magnetic strip 130 is disposed on the support member 110 , and the magnetic strip 130 is located between the support member 110 and the coil.

[0095] By setting the magnetic strip 130, the distribution of the electromagnetic field on the side of the coil facing away from the cooking utensil 300 can be changed, so that the electromagnetic field generated by the coil can be concentrated on the side where the cooking utensil 300 is located, so as to centrally heat the cooking utensil 300 and achieve the technical effect of improving the electromagnetic heating efficiency and electromagnetic heating energy efficiency.

[0096] like Figure 8As shown, in some embodiments of the present invention, specifically, the length direction of the magnetic strip 130 ( Figure 8 The arrow g in the middle indicates that the radial direction of the coil is consistent; there are multiple magnetic strips 130, and the multiple magnetic strips 130 are evenly distributed in the circumferential direction of the coil.

[0097] Figure 8 , arrow f shows the axial direction of the coil.

[0098] In this embodiment, the length direction of the magnetic strip 130 is consistent with the radial direction of the coil. By arranging the magnetic strip 130 along the radial direction of the coil, the deflection effect of the electromagnetic field can be enhanced to concentrate the electromagnetic field on the cooking utensil 300 on the other side.

[0099] On this basis, there are multiple magnetic strips 130, and the multiple magnetic strips 130 are evenly distributed in the circumferential direction of the coil. By setting up multiple evenly distributed magnetic strips 130, the magnetic field deflection blind spot on the side of the coil facing away from the cooking utensil 300 can be avoided, thereby further improving the electromagnetic heating effect of the coil disk 100.

[0100] like Figure 8 As shown, in some embodiments of the present invention, specifically, the coil disk 100 further includes: a heat insulation layer 140, which is provided on the support component 110 and is located between the support component 110 and the coil.

[0101] In this embodiment, a thermal insulation layer 140 is provided on the side of the support component 110 facing the coil. This layer prevents heat generated by the coil from being transferred to the support component 110. This layer prevents the high-temperature coil from burning the support component 110 and concentrates the heat generated by the coil on the side where the cooking device 300 is located. This improves the safety and reliability of the coil disk 100 and enhances the energy efficiency of infrared heating.

[0102] Specifically, the heat insulating layer 140 has a temperature resistance of at least 400° C. The material of the heat insulating layer 140 can be a mixture of white carbon black and moissanite, or can be flexible vacuum silicon insulation cotton.

[0103] like Figure 9 As shown, an embodiment of the present invention provides a cooking device 200 , which includes: a body 210 ; and a coil disk 100 such as in any of the above embodiments, which is disposed on the body 210 .

[0104] In this embodiment, a cooking device 200 is provided that includes the coil disk 100 described in any of the aforementioned embodiments. Therefore, the cooking device 200 possesses the advantages and can achieve the technical effects of the coil disk 100 described in any of the aforementioned embodiments. To avoid repetition, further details will be omitted.

[0105] On this basis, the cooking device 200 also includes a main body 210, which is the main frame structure of the cooking device 200. The main body 210 is used to position, support and protect other working structures on the cooking device 200. The coil disk 100 can be set inside the main body 210, and the coil disk 100 can also be embedded on the top of the main body 210 to heat the cooking utensils 300 placed on the cooking device 200 through the coil disk 100.
