技术领域Technical Field

本实用新型涉及烹饪器具领域,尤其涉及一种屏蔽件、线盘组件及烹饪器具。The utility model relates to the field of cooking utensils, in particular to a shielding component, a wire reel assembly and a cooking utensil.

背景技术Background technique

常规烹饪器具的线圈盘的绕线方式为单侧绕线,由于烹饪器具的工作电流和频率等工作参数的约束,此种线圈盘与锅具耦合后的加热高度较低,只能在锅底产生涡流,对锅具的底部进行加热,难以对锅具的侧壁进行有效加热,因此,如何提高对锅具侧壁的加热效果成为需要解决的技术问题。The coil disk of a conventional cooking appliance is wound on one side. Due to the constraints of the working parameters of the cooking appliance, such as the working current and frequency, the heating height of this coil disk after coupling with the cookware is relatively low, and it can only generate eddy currents at the bottom of the cookware to heat the bottom of the cookware, but it is difficult to effectively heat the side walls of the cookware. Therefore, how to improve the heating effect on the side walls of the cookware becomes a technical problem that needs to be solved.

现有技术中,有考虑设置凹形线圈盘,凹形线圈盘的底部用以对锅具的底部加热,凹形线圈盘的侧部对锅具的侧部加热,但是该凹形线圈盘的尺寸比较大。In the prior art, it is considered to provide a concave coil disk, the bottom of the concave coil disk is used to heat the bottom of the cookware, and the side of the concave coil disk heats the side of the cookware, but the size of the concave coil disk is relatively large.

实用新型内容Utility Model Content

为了提高线圈盘对锅具侧壁的加热效果,发明人有想到采用双侧绕线的方式进行绕线,从而能够提高与锅具耦合后的加热高度,进而能够对锅具的侧壁进行有效的加热,如此设置,由于其下层线组也会产生交变磁场,使得线盘总体感量增加,耦合变弱,且有底部磁场也会使线圈盘底部附近区域的金属元件器发热,同时发出大量电磁辐射,故必须在线盘下层线圈上方、磁条下方,或者整个线圈盘的底部,增加屏蔽金属件,以此减小线盘总体感量,增强耦合,实现大功率加热效果,同时屏蔽下方磁场,解决底部加热,解决底部辐射问题。In order to improve the heating effect of the coil disk on the side wall of the cooker, the inventor conceived of using a double-sided winding method to wind the wire, thereby increasing the heating height after coupling with the cooker, and further effectively heating the side wall of the cooker. With this arrangement, since the lower wire group will also generate an alternating magnetic field, the overall inductance of the coil disk will increase and the coupling will weaken. The bottom magnetic field will also cause the metal components near the bottom of the coil disk to heat up and emit a large amount of electromagnetic radiation. Therefore, it is necessary to add shielding metal parts above the lower coil of the coil disk, below the magnetic strip, or at the bottom of the entire coil disk to reduce the overall inductance of the coil disk, enhance coupling, achieve high-power heating effect, and shield the magnetic field below to solve the bottom heating and bottom radiation problems.

但是屏蔽金属件与绕线接触或间隙很小,且一般为完整没有开孔的金属板,当线圈盘通电工作时,其绕线会发热,屏蔽金属件就会妨碍温度较低的空气与绕线的对流,绕线与外部的热交换效果变差,从而使得线圈盘的散热较差。However, the shielding metal part is in contact with the winding or the gap is very small, and it is generally a complete metal plate without openings. When the coil disk is energized, its winding will heat up, and the shielding metal part will hinder the convection between the lower temperature air and the winding, and the heat exchange effect between the winding and the outside will be reduced, resulting in poor heat dissipation of the coil disk.

本实用新型的主要目的是提出一种屏蔽件、线盘组件及烹饪器具,旨在解决带屏蔽件的线圈盘散热较差的问题。The main purpose of the utility model is to provide a shielding member, a coil assembly and a cooking utensil, aiming to solve the problem of poor heat dissipation of a coil coil with a shielding member.

为了提高线圈盘对锅具侧壁的加热效果,发明人有想到采用双侧绕线的方式进行绕线,从而能够提高与锅具耦合后的加热高度,进而能够对锅具的侧壁进行有效的加热,如此设置,其下层线组也会产生交变磁场,使得线盘总体感量增加,耦合变弱,且有底部磁场也会使线圈盘底部附近区域的金属元件器发热,同时发出大量电磁辐射,故必须在线盘下层线圈上方、磁条下方,或者整个线圈盘的底部,增加屏蔽金属件,以此减小线盘总体感量,增强耦合,实现大功率加热效果,同时屏蔽下方磁场,解决底部加热,解决底部辐射问题。In order to improve the heating effect of the coil disk on the side wall of the cooker, the inventor conceived of using a double-sided winding method to wind the wire, thereby increasing the heating height after coupling with the cooker, and further effectively heating the side wall of the cooker. With this arrangement, the lower wire group will also generate an alternating magnetic field, which increases the overall inductance of the coil disk and weakens the coupling. The bottom magnetic field will also cause the metal components near the bottom of the coil disk to heat up and emit a large amount of electromagnetic radiation. Therefore, it is necessary to add shielding metal parts above the lower coil of the coil disk, below the magnetic strip, or at the bottom of the entire coil disk to reduce the overall inductance of the coil disk, enhance coupling, achieve high-power heating effect, and at the same time shield the magnetic field below to solve the bottom heating and bottom radiation problems.

但是屏蔽金属件与绕线接触或间隙很小,且一般为完整没有开孔的金属板,当线圈盘通电工作时,其绕线会发热,屏蔽金属件就会妨碍温度较低的空气与绕线的对流,绕线与外部的热交换效果变差,从而使得线圈盘的散热较差。However, the shielding metal part has very small contact or gap with the winding, and is generally a complete metal plate without openings. When the coil disk is energized, the winding will heat up, and the shielding metal part will hinder the convection between the lower temperature air and the winding, and the heat exchange effect between the winding and the outside will be reduced, resulting in poor heat dissipation of the coil disk.

为了解决上述问题,本实用新型提供一种屏蔽件、线盘组件及烹饪器具,图1至图4为本实用新型提供的线圈组件的具体实施例。In order to solve the above problems, the utility model provides a shielding member, a wire reel assembly and a cooking utensil. FIG. 1 to FIG. 4 are specific embodiments of the coil assembly provided by the utility model.

请参阅图1至图3,所述屏蔽件100用于线盘组件1000中,用以安装在所述线盘组件1000的支架200的第二侧,且位于所述支架200的第二侧的多个第二导线段312背对支架200的一侧,所述屏蔽件100包括主体部1,所述主体部1用以安装在所述支架200的第二侧,所述主体部1上设置有开孔11。Please refer to Figures 1 to 3. The shielding component 100 is used in the wire reel assembly 1000, and is used to be installed on the second side of the bracket 200 of the wire reel assembly 1000, and the multiple second wire segments 312 located on the second side of the bracket 200 are facing away from the side of the bracket 200. The shielding component 100 includes a main body 1, and the main body 1 is used to be installed on the second side of the bracket 200. The main body 1 is provided with an opening 11.

本实用新型提供的技术方案中,所述屏蔽件100用于线盘组件1000中,用以安装在所述线盘组件1000的支架200的第二侧,且位于所述支架200的第二侧的多个第二导线段312背对支架200的一侧,以此减小所述线盘组件1000的总体感量,增强耦合,实现大功率加热效果,同时屏蔽所述多个第二导线段312产生的交变磁场,解决所述支架200第二侧的加热和辐射问题,所述屏蔽件100包括主体部1,所述主体部1用以安装在所述支架200的第二侧,所述主体部1上设置有开孔11,由于所述线盘组件1000在通电工作时会发热,通过所述开孔11促进温度较低的空气与所述线盘组件1000对流,以提升所述线盘组件1000与外部的热交换效果,从而解决了带屏蔽件100的线盘组件1000散热较差的问题。In the technical solution provided by the utility model, the shielding member 100 is used in the wire reel assembly 1000, and is used to be installed on the second side of the bracket 200 of the wire reel assembly 1000, and the multiple second wire segments 312 located on the second side of the bracket 200 are facing away from the side of the bracket 200, so as to reduce the overall inductance of the wire reel assembly 1000, enhance coupling, and achieve a high-power heating effect. At the same time, the alternating magnetic field generated by the multiple second wire segments 312 is shielded to solve the heating and radiation problems of the second side of the bracket 200. The shielding member 100 includes a main body 1, and the main body 1 is used to be installed on the second side of the bracket 200. The main body 1 is provided with an opening 11. Since the wire reel assembly 1000 will generate heat when it is powered on, the opening 11 promotes convection between air with a lower temperature and the wire reel assembly 1000, so as to improve the heat exchange effect between the wire reel assembly 1000 and the outside, thereby solving the problem of poor heat dissipation of the wire reel assembly 1000 with the shielding member 100.

进一步地,所述开孔11的数量和布设方式不做限制,只要保证所述开孔11可以促进温度较低的空气和所述线盘组件1000对流,以降低所述线盘组件1000的温度即可,例如在本实施例中,如图1所示,所述开孔11设置多个,所述开孔11的数量越多,能够与所述线盘组件1000产生对流的冷空气越多,则所述线盘组件1000与外部的热交换效果越好,从而使得所述线盘组件1000的散热效果越好。同时所述多个开孔11至少沿着所述主体部1的周向分布,如此设置使得所述多个开孔11的布设更加均匀,进而如图5所示,使得冷空气可以均匀地与所述线盘组件1000产生对流。Furthermore, there is no restriction on the number and arrangement of the openings 11, as long as the openings 11 can promote convection between the air with a lower temperature and the cable drum assembly 1000 to reduce the temperature of the cable drum assembly 1000. For example, in this embodiment, as shown in FIG1 , a plurality of openings 11 are provided. The more openings 11 there are, the more cold air can be convected with the cable drum assembly 1000, and the better the heat exchange effect between the cable drum assembly 1000 and the outside, thereby making the heat dissipation effect of the cable drum assembly 1000 better. At the same time, the plurality of openings 11 are distributed at least along the circumference of the main body 1. Such an arrangement makes the arrangement of the plurality of openings 11 more uniform, and as shown in FIG5 , the cold air can evenly convect with the cable drum assembly 1000.

同样地,所述多个开孔11的布设方式也可以如图1所示,所述多个开孔11至少沿着远离所述主体部1的中心方向上分布,除此之外,所述多个开孔11的布设方式可以是其他本领域技术人员公知的布设方式,具体布设方式可以根据实际情况决定。Similarly, the arrangement of the multiple openings 11 can also be as shown in Figure 1, and the multiple openings 11 are distributed at least along the center direction away from the main body 1. In addition, the arrangement of the multiple openings 11 can be other arrangement methods known to technical personnel in this field, and the specific arrangement method can be determined according to actual conditions.

上述两个技术特征可以择一设置,也可以同时设置,在本实施例中,选择同时设置,即所述开孔11设置多个,所述多个开孔11至少沿着所述主体部1的周向分布,且所述多个开孔11至少沿着远离所述主体部1的中心方向上分布。更进一步地,沿着所述主体部1的周向分布的所述多个开孔11之间的距离保持一致,沿着远离所述主体部1的中心方向上分布的所述多个开孔11之间的距离保持一致,如此设置,使得所述多个开孔11均匀地分布在所述屏蔽件100的所述主体部1上,进而使得所述线盘组件1000各处均可以与冷空气产生对流,所述线盘组件1000各处与外部的热交换效果尽量保持一致,所述线盘组件1000各处降低的温度保持一致。The above two technical features can be set selectively or simultaneously. In the present embodiment, they are set simultaneously, that is, a plurality of openings 11 are set, and the plurality of openings 11 are distributed at least along the circumference of the main body 1, and the plurality of openings 11 are distributed at least along the central direction away from the main body 1. Furthermore, the distances between the plurality of openings 11 distributed along the circumference of the main body 1 are kept consistent, and the distances between the plurality of openings 11 distributed along the central direction away from the main body 1 are kept consistent. Such a setting makes the plurality of openings 11 evenly distributed on the main body 1 of the shielding member 100, so that convection can be generated at all locations of the wire drum assembly 1000 with cold air, and the heat exchange effect between the wire drum assembly 1000 and the outside is kept as consistent as possible, and the temperature reduction at all locations of the wire drum assembly 1000 is kept consistent.

所述开孔11的形状同样不做限制,只要保证所述开孔11可以促进温度较低的空气和所述线盘组件1000对流,以降低所述线盘组件1000的温度即可,如图6、图7和图8所示,所述开孔11的形状可以是圆孔、方孔、长条孔、三角形,或者其他本领域技术人员公知的开孔11形状,也可以是多种不同的形状共同设置。There is no limitation on the shape of the opening 11, as long as the opening 11 can promote convection between the air with lower temperature and the wire drum assembly 1000 to reduce the temperature of the wire drum assembly 1000. As shown in FIGS. 6, 7 and 8, the shape of the opening 11 can be a round hole, a square hole, a long hole, a triangle, or other shapes of the opening 11 known to those skilled in the art, or a plurality of different shapes can be arranged together.

但是所述开孔11的面积受到限制,如果所述开孔11的面积过大,可能导致所述屏蔽件100的有效工作面积减少,泄露较多磁场,进而导致所述屏蔽件100的屏蔽作用减弱,或失去屏蔽作用。However, the area of the opening 11 is limited. If the area of the opening 11 is too large, the effective working area of the shielding element 100 may be reduced, resulting in more magnetic field leakage, thereby weakening the shielding effect of the shielding element 100 or losing the shielding effect.

由于所述屏蔽件100的有效工作面积越大,屏蔽效果越好,但是过大的有效工作面积会导致所述开孔11的面积过小,进而影响所述线盘组件1000的散热,为了提升所述屏蔽件100的屏蔽效果的同时不影响所述线盘组件1000的散热效果,所述屏蔽件100还包括设于所述主体部1的侧部2,此时所述侧部2对应位置的散热效果较差,在本实施例中,如图4所示,所述侧部2形成有开口21,通过所述开口21可以提升所述侧部2对应位置与外部的热交换效果,以确保散热不受影响。Since the larger the effective working area of the shielding component 100, the better the shielding effect, but an excessively large effective working area will cause the area of the opening 11 to be too small, thereby affecting the heat dissipation of the cable reel assembly 1000. In order to improve the shielding effect of the shielding component 100 without affecting the heat dissipation effect of the cable reel assembly 1000, the shielding component 100 also includes a side portion 2 arranged on the main body 1. At this time, the heat dissipation effect of the corresponding position of the side portion 2 is poor. In this embodiment, as shown in Figure 4, the side portion 2 is formed with an opening 21, and the opening 21 can improve the heat exchange effect between the corresponding position of the side portion 2 and the outside to ensure that the heat dissipation is not affected.

进一步地,所述侧部2的数量不做限制,只要保证所述侧部2可以提升所述屏蔽件100的屏蔽效果即可,例如在本实施例中,如图4所示,所述侧部2设有多个,且所述多个侧部2沿着所述主体部1的周向间隔分布,如此设置,各所述侧部2之间存在间隙,在保证所述屏蔽件100的屏蔽效果得到提升的同时,还可以提升各所述侧部2之间的间隙处与外部的热交换效果,进而促进所述线盘组件1000的散热。Furthermore, there is no limit to the number of the side portions 2, as long as the side portions 2 can enhance the shielding effect of the shielding component 100. For example, in the present embodiment, as shown in FIG. 4 , a plurality of side portions 2 are provided, and the plurality of side portions 2 are distributed at circumferential intervals along the main body 1. With such a configuration, there are gaps between the side portions 2. While enhancing the shielding effect of the shielding component 100, the heat exchange effect between the gaps between the side portions 2 and the outside can also be enhanced, thereby promoting the heat dissipation of the wire reel assembly 1000.

为了更进一步提升所述线盘组件1000的散热效果,在本实施例中,如图1所示,所述主体部1的中部还设有过孔12,所述过孔12与所述开孔11错开设置。如此设置,增加了能够与所述线盘组件1000产生对流的冷空气,使得所述线盘组件1000与外部的热交换效果得以提升,从而使得所述线盘组件1000的散热效果更好。In order to further improve the heat dissipation effect of the cable drum assembly 1000, in this embodiment, as shown in FIG1 , a through hole 12 is further provided in the middle of the main body 1, and the through hole 12 is staggered with the opening 11. Such a configuration increases the cold air that can generate convection with the cable drum assembly 1000, so that the heat exchange effect between the cable drum assembly 1000 and the outside is improved, thereby achieving a better heat dissipation effect of the cable drum assembly 1000.

同时所述开孔11设置为多个,更进一步增加了能够与所述线盘组件1000产生对流的冷空气,提升了所述线盘组件1000的散热效果,且所述多个开孔11至少沿着所述过孔12的周向分布,使得所述多个开孔11的布设更加均匀,进而使得冷空气可以均匀地与所述线盘组件1000产生对流。At the same time, the openings 11 are arranged in a plurality, which further increases the cold air that can generate convection with the wire reel assembly 1000, thereby improving the heat dissipation effect of the wire reel assembly 1000, and the plurality of openings 11 are at least distributed along the circumference of the through hole 12, so that the layout of the plurality of openings 11 is more uniform, thereby allowing the cold air to generate convection with the wire reel assembly 1000 evenly.

所述开孔11的布设方式还可以设置为沿着所述过孔12的径向分布,两种布设方式可以择一设置,也可以同时设置,在本实施例中,将两种布设方式同时设置,即所述开孔11设置为多个,所述多个开孔11至少沿着所述过孔12的周向分布,且所述多个开孔11至少沿着所述过孔12的径向分布,如此设置,使得所述多个开孔11均匀地分布在所述屏蔽件100的所述主体部1上,进而使得所述线盘组件1000各处均可以与冷空气产生对流,所述线盘组件1000各处与外部的热交换效果尽量保持一致,所述线盘组件1000各处降低的温度保持一致。The arrangement of the openings 11 can also be set to be distributed radially along the through-holes 12. The two arrangement methods can be set selectively or simultaneously. In the present embodiment, the two arrangement methods are set simultaneously, that is, the openings 11 are set to be multiple, and the multiple openings 11 are at least distributed circumferentially along the through-holes 12, and the multiple openings 11 are at least distributed radially along the through-holes 12. Such an arrangement allows the multiple openings 11 to be evenly distributed on the main body 1 of the shielding component 100, thereby allowing convection to occur at various locations of the wire drum assembly 1000 with cold air, and the heat exchange effect between the wire drum assembly 1000 and the outside is kept as consistent as possible, and the temperature reduction at various locations of the wire drum assembly 1000 is kept consistent.

为了能够对锅具的侧壁进行加热,本实用新型还提供一种线盘组件1000,所述线盘组件1000包括支架200、线圈单元300和屏蔽件100,所述支架200具有在第一方向上呈相对的第一侧和第二侧,所述线圈单元300设于所述支架200上,所述线圈单元300包括多匝线圈310,各匝所述线圈310包括电流相反且相互连接的第一导线段311和第二导线段312,所述多匝线圈310绕设于所述支架200的第一侧和第二侧,以使得所述支架200的第一侧分布有多个所述第一导线段311、所述支架200的第二侧分布有多个第二导线段312,所述屏蔽件100设于所述支架200的第二侧,且位于所述多个第二导线段312背对所述支架200的一侧,所述屏蔽件100为上述各实施例中任意一项所述的屏蔽件100,由于所述线盘组件1000采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果,在此不再一一赘述。In order to heat the side wall of the cookware, the utility model further provides a wire reel assembly 1000, the wire reel assembly 1000 includes a bracket 200, a coil unit 300 and a shielding member 100, the bracket 200 has a first side and a second side opposite to each other in a first direction, the coil unit 300 is arranged on the bracket 200, the coil unit 300 includes a multi-turn coil 310, each turn of the coil 310 includes a first wire segment 311 and a second wire segment 312 with opposite currents and connected to each other, the multi-turn coil 310 is wound around the first side and the second side of the bracket 200, So that a plurality of first wire segments 311 are distributed on the first side of the bracket 200, and a plurality of second wire segments 312 are distributed on the second side of the bracket 200. The shielding component 100 is arranged on the second side of the bracket 200, and is located on the side of the plurality of second wire segments 312 facing away from the bracket 200. The shielding component 100 is the shielding component 100 described in any one of the above-mentioned embodiments. Since the wire reel assembly 1000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

在本实用新型提供的技术方案中,所述线圈单元300设于所述支架200上,所述线圈单元300包括多匝线圈310,各匝所述线圈310包括电流相反且相互连接的第一导线段311和第二导线段312,所述支架200的第一侧分布有多个所述第一导线段311、所述支架200的第二侧分布有多个第二导线段312,使得所述支架200的第一侧和第二侧分别产生两个相反方向的交变磁场,所述支架200的第一侧的多个所述第一导线段311产生的交变磁场能够提高与锅具耦合后的加热高度,进而能够对锅具的侧壁进行有效的加热,但是所述支架200的第二侧的多个所述第二导线段312产生的相反方向的交变磁场会和所述第一导线段311产生的交变磁场相抵消,导致耦合变弱,并且该交变磁场会使得第二侧附近区域的金属元件器发热,同时发出大量电磁辐射,因此所述支架200的第二侧设置有所述屏蔽件100,用以屏蔽多个所述第二导线段312产生的交变磁场,由于设置所述屏蔽件100会妨碍温度较低的空气与所述线盘组件1000的对流,所述线盘组件1000与外部的热交换效果变差,从而使得所述线盘组件1000的散热较差,故而在所述屏蔽件100的所述主体部1上设置有所述开孔11,以促进冷空气与所述线盘组件1000的对流,解决所述线盘组件1000散热较差的问题。In the technical solution provided by the present utility model, the coil unit 300 is arranged on the bracket 200, and the coil unit 300 includes a plurality of turns of coil 310, each turn of the coil 310 includes a first wire segment 311 and a second wire segment 312 with opposite currents and connected to each other, a plurality of the first wire segments 311 are distributed on the first side of the bracket 200, and a plurality of the second wire segments 312 are distributed on the second side of the bracket 200, so that the first side and the second side of the bracket 200 respectively generate two alternating magnetic fields in opposite directions, and the alternating magnetic fields generated by the plurality of the first wire segments 311 on the first side of the bracket 200 can increase the heating height after coupling with the cookware, thereby effectively heating the side wall of the cookware, but the plurality of the second wire segments 312 on the second side of the bracket 200 generate the alternating magnetic fields in opposite directions. The alternating magnetic field in the opposite direction will offset the alternating magnetic field generated by the first wire segment 311, resulting in weakened coupling, and the alternating magnetic field will cause the metal components in the vicinity of the second side to heat up and emit a large amount of electromagnetic radiation. Therefore, the shielding member 100 is provided on the second side of the bracket 200 to shield the alternating magnetic field generated by the plurality of second wire segments 312. Since the shielding member 100 hinders the convection between the lower temperature air and the wire reel assembly 1000, the heat exchange effect between the wire reel assembly 1000 and the outside is deteriorated, thereby making the heat dissipation of the wire reel assembly 1000 poor. Therefore, the opening 11 is provided on the main body 1 of the shielding member 100 to promote the convection between the cold air and the wire reel assembly 1000, so as to solve the problem of poor heat dissipation of the wire reel assembly 1000.

进一步地,由于金属材质的屏蔽效果更好,所述屏蔽件100的材质为金属材质,可以更好地屏蔽所述多个第二导线段312产生的交变磁场,并且由于金属材质的导热性能较好,金属材质的所述屏蔽件100可以提升所述线盘组件1000的散热效果。Furthermore, since metal materials have better shielding effects, the shielding component 100 is made of metal material, which can better shield the alternating magnetic field generated by the multiple second wire segments 312, and since metal materials have good thermal conductivity, the shielding component 100 made of metal material can improve the heat dissipation effect of the wire reel assembly 1000.

同时,如图3所示,所述开孔11设置为多个且呈条形孔设置,所述开孔11的布设路径与所述第二导线段312形状相对应,以使得相邻的两个所述开孔11之间限定出一与所述第二导线段312相对的金属段。如此设置,所述屏蔽件100在所述多个第二导线段312产生的交变磁场下,会产生一个尽量大的交变磁场,该交变磁场的部分磁场与所述第二导线段312产生的交变磁场相抵消,以提升所述屏蔽件100的屏蔽效果。Meanwhile, as shown in FIG3 , the openings 11 are arranged in a plurality of strip-shaped holes, and the arrangement path of the openings 11 corresponds to the shape of the second wire segments 312, so that a metal segment opposite to the second wire segments 312 is defined between two adjacent openings 11. With such an arrangement, the shielding member 100 will generate an alternating magnetic field as large as possible under the alternating magnetic field generated by the plurality of second wire segments 312, and a part of the magnetic field of the alternating magnetic field will offset the alternating magnetic field generated by the second wire segments 312, so as to enhance the shielding effect of the shielding member 100.

进一步地,所述开孔11与所述第二导线段312的延伸方向一致或者呈倾斜夹角设置,使得所述屏蔽件100可以产生一个与所述第二导线段312的交变磁场相反的交变磁场,两个交变磁场的部分相抵消,以提升所述屏蔽件100的屏蔽效果。Furthermore, the opening 11 is consistent with the extension direction of the second wire segment 312 or is set at an inclined angle, so that the shielding component 100 can generate an alternating magnetic field that is opposite to the alternating magnetic field of the second wire segment 312, and the two alternating magnetic fields partially offset each other to enhance the shielding effect of the shielding component 100.

具体地,在本实施例中,所述夹角为a,0°≤a<45°,以使得所述开孔11的延伸方向与所述第二导线段312产生的感应涡流方向几乎一致,进而使得所述屏蔽件100产生的相反方向的交变磁场可以与所述第二导线段312产生的交变磁场可以几乎抵消,最大限度提升所述屏蔽件100的屏蔽效果。Specifically, in this embodiment, the angle is a, 0°≤a<45°, so that the extension direction of the opening 11 is almost consistent with the direction of the induced eddy current generated by the second wire segment 312, so that the alternating magnetic field in the opposite direction generated by the shielding component 100 can be almost offset by the alternating magnetic field generated by the second wire segment 312, thereby maximizing the shielding effect of the shielding component 100.

此外,本实用新型还提供一种烹饪器具10000,所述烹饪器具10000包括线盘组件1000,所述线盘组件1000为上述各实施例中任意一项所述的线盘组件1000,由于所述烹饪器具10000采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果,在此不再一一赘述。In addition, the utility model also provides a cooking utensil 10000, which includes a wire reel assembly 1000, and the wire reel assembly 1000 is the wire reel assembly 1000 described in any one of the above-mentioned embodiments. Since the cooking utensil 10000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

需要说明的是,所述烹饪器具10000包括电磁炉、电饭煲以及其他本领域技术人员公知的采用电磁加热方式的烹饪器具。It should be noted that the cooking utensil 10000 includes an induction cooker, an electric rice cooker, and other cooking utensil using electromagnetic heating that are well known to those skilled in the art.

在本实施例中,待加热件置于所述烹饪器具10000上,多个所述第一导线段311产生的磁场用于与置于所述支架200的第一侧的待加热件(锅具等)的底部耦合,且还用于与待加热件的侧壁耦合,以对待加热件的侧壁加热。在现有的包装外壳下,在加热面有限的前提下,因所述线圈单元300具有更大的加热辐射范围,所述线圈单元300产生的磁场与待加热件的有效耦合面积更大,不仅能够对待加热件的底部加热,还能够对待加热件的侧壁加热,实现立体加热,使得待加热件加热效果更佳均匀,并且能够提升加热的效率,减少用户的使用成本。In this embodiment, the heated part is placed on the cooking utensil 10000, and the magnetic field generated by the plurality of first wire segments 311 is used to couple with the bottom of the heated part (cooker, etc.) placed on the first side of the bracket 200, and is also used to couple with the side wall of the heated part to heat the side wall of the heated part. Under the existing packaging shell, under the premise of limited heating surface, because the coil unit 300 has a larger heating radiation range, the effective coupling area of the magnetic field generated by the coil unit 300 and the heated part is larger, which can not only heat the bottom of the heated part, but also heat the side wall of the heated part, realizing three-dimensional heating, making the heating effect of the heated part more uniform, and can improve the heating efficiency, reducing the user's use cost.

以上所述仅为本实用新型的优选实施例,并非因此限制本实用新型的专利范围,凡是在本实用新型的构思下,利用本实用新型说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本实用新型的专利保护范围内。The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
