The electromagnetic heating assembly provided by the embodiment comprises a disk seat, at least two coils, a magnetic core and at least one magnetic core bracket. The dish seat can provide support for the pot body, and the coil can produce alternating magnetic field as electromagnetic heating element. Under the action of the alternating magnetic field, the pot body with magnetic conductivity can generate heat, thereby realizing cooking. Specifically, bubbles can be generated on the surface of the pot body and flushed into liquid in the pot body, so that the liquid at the position where the bubbles are flushed out is heated. Specifically, the number of the coils is at least two, the coils are located on one side of the dish seat, which is far away from the pan body, and the coils are distributed at intervals. Through the back at the dish seat, also at least two coils of one side interval distribution that the dish seat deviates from the pot body for the pot body of placing in the dish seat can receive the heating of two at least coils of different positions, with in the correlation technique at the lateral wall department of the pot body or the diapire department of the pot body continuous distribution coil, make the pot body only have a great heated area compare, realized that heated area is changed into a plurality of little heated areas from single big circular heated area, be favorable to increasing the tumbling frequency and the homogeneity of being heated of edible material in the pot body, improve the inhomogeneous problem of the doneness of edible material in the pot body.

For example, when the pot body is used for cooking rice, the coils are used as electromagnetic heating elements, bubbles are generated on the surface of the pot body by heat generated by heating, and the bubbles are washed out at thin parts of the conjunctiva due to the fact that the rice forms the conjunctiva at the surface contacting with the surface of the pot body, wherein the thin parts of the conjunctiva are positions corresponding to the central part and the outer part of each coil. A part of bubbles are flushed out from the position corresponding to the central part of the coil, and the rice-water mixture in the middle of the pot body is uniformly heated by the brought heat; the other part of the bubbles are flushed out from the position corresponding to the outside of the coil, and the brought heat enables the rice-water mixture on the side wall of the pot body to be uniformly heated.

Specifically, each magnetic core support strides across the middle of at least one coil to avoid the dead zone, so that the magnetic cores arranged on the magnetic core supports skip or cross the middle to avoid the dead zone and correspond to the coils, the magnetic field intensity is increased, and the heating effect of the electromagnetic heating assembly is improved. For example, in the case that a plurality of coils extend from the disk side portion of the disk seat to the disk bottom portion, part or all of the magnetic core supports may also extend from the disk side portion of the disk seat to the disk bottom portion of the disk seat and cross over the middle of the coils to avoid the empty area, at this time, the magnetic cores located on the magnetic core supports may respectively correspond to the partial coils on the disk bottom portion of the disk seat and the partial coils on the disk side portion of the disk seat, which is beneficial to enhancing the magnetic field intensity of the bottom and side portions of the pot body, thereby enhancing the heating effect of the electromagnetic heating assembly. Of course, the magnetic core bracket can also transversely penetrate through the middle space avoiding area of the coil and can have various arrangement positions.

It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The electromagnetic heating assembly and the electromagnetic cooking appliance of some embodiments of the present invention are described below with reference to fig. 3 to 8.

The first embodiment is as follows:

as shown in fig. 7 and 8, an electromagnetic heating assembly includes a tray 100, at least two coils 200, a magnetic core 400, and at least one core holder 300. Specifically, at least two coils 200 are distributed at intervals on one side of the tray 100, and each coil 200 can enclose a middle keep-out area 230; the magnetic core supports 300 are all arranged on one sides of the at least two coils 200 departing from the tray 100, so that the magnetic cores 400 are arranged on one sides of the coils 200 departing from the tray 100, at least one magnetic core 400 is arranged on each magnetic core support 300, and each magnetic core support 300 is connected with the tray 100 through the middle space avoiding area 230.

The electromagnetic heating assembly proposed in the present embodiment includes a tray 100, at least two coils 200, a magnetic core 400, and at least one core holder 300. The tray 100 can provide support for the pot body, and the coil 200 can generate an alternating magnetic field as an electromagnetic heating element. Under the action of the alternating magnetic field, the pot body with magnetic conductivity can generate heat, thereby realizing cooking. Specifically, bubbles can be generated on the surface of the pot body and flushed into liquid in the pot body, so that the liquid at the position where the bubbles are flushed out is heated. Specifically, the number of the coils 200 is at least two, and the coils are located on one side of the tray 100 facing away from the pan body and are distributed at intervals. Through the back of the dish seat 100, namely the side of the dish seat 100 departing from the pot body is distributed with at least two coils 200 at intervals, the pot body placed in the dish seat 100 can be heated by the at least two coils 200 at different positions, compared with the prior art that the coils 200 are continuously distributed at the side wall of the pot body or the bottom wall of the pot body, the pot body is only provided with a larger heated area, the heated area is changed from a single large-circle heated area into a plurality of small heated areas, the rolling frequency and the heating uniformity of food materials in the pot body are increased, and the problem of uneven cooking degree of the food materials in the pot body is solved.

For example, when the pot body is used for cooking rice, the coils 200 are used as electromagnetic heating elements, bubbles are generated on the surface of the pot body by heat generated by heating, and the bubbles are flushed out at the thin parts of the conjunctiva formed by the surfaces of the rice contacting with the surface of the pot body, wherein the thin parts of the conjunctiva are positions corresponding to the central part and the outer part of each coil 200. A part of bubbles are flushed out from the position corresponding to the central part of the coil 200, and the rice-water mixture in the middle of the pot body is uniformly heated by the brought heat; the other part of the bubbles are flushed out from the position corresponding to the outside of the coil 200, and the brought heat enables the rice-water mixture at the side wall of the pot body to be uniformly heated. Compared with the prior art, the embodiment of the utility model provides an electromagnetic cooking utensil has a plurality of interval distribution's coil 200, is favorable to the bubble to dash out from a plurality of positions, is favorable to providing sufficient heat for pot body middle part, guarantees that the rice water mixture at pot body middle part is heated evenly, promotes the taste. When food with more liquid is cooked, for example, porridge is cooked, because the rice is less than water and more than water, the contact area of the rice and the surface of the pot body is small, only a small amount of conjunctiva is formed, bubbles can be flushed out from all parts of the coil 200, the heat can be brought to the middle part of the pot body, and because the rice is small in size and the rice in the pot is small, the bubbles can fully disturb the liquid in the pot, the heat transfer effect in the liquid is further improved, and the uniform heating of the rice-water mixture is realized. If the above-mentioned conjunctiva is not formed during cooking soup, the bubbles can be continuously flushed out from each part of the coil 200, and the heat can be also brought to the middle part of the pot body, so that the food is uniformly heated.

In addition, the magnetic core 400 is installed on the magnetic core bracket 300 by arranging the magnetic core bracket 300 on the tray 100 and enabling the coil 200 to be positioned between the magnetic core bracket 300 and the tray 100, namely, the magnetic core 400 is arranged on one side of the coil 200 departing from the pot body. The existence of magnetic core 400 plays the effect of changing magnetic field intensity and local direction, is favorable to strengthening the magnetic field intensity that coil 200 acted on the pot body of electromagnetic cooking utensil to improve heating efficiency. Specifically, by making each core holder 300 cross the middle keep-out area 230 of at least one coil 200, it is beneficial for the core 400 disposed on the core holder 300 to jump or cross the middle keep-out area 230 to correspond to the coil 200, thereby being beneficial to increasing the magnetic field intensity and improving the heating effect of the electromagnetic heating assembly. For example, in the case that a plurality of coils 200 extend from the tray side portion 130 to the tray bottom portion 110 of the tray 100, a part or all of the magnetic core holders 300 may also extend from the tray side portion 130 to the tray bottom portion 110 of the tray 100 and span the middle space 230 of the coils 200, at this time, the magnetic cores 400 on the magnetic core holders 300 can respectively correspond to the partial coils 200 on the tray bottom portion 110 of the tray 100 and the partial coils 200 on the tray side portion 130 of the tray 100, which is beneficial to enhancing the magnetic field intensity of the bottom and side portions of the pot body, thereby enhancing the heating effect of the electromagnetic heating assembly. Of course, the core holder 300 may also be disposed across the central keep-out region 230 of the coil 200, and may have various positions.

And the magnetic core support 300 is connected with the tray 100 through the middle space-avoiding area 230 of one or more coils 200, and the magnetic field intensity of the middle space-avoiding area 230 of the coils 200 is weaker, so that the phenomena that the connecting piece of the magnetic core support 300 and the tray 100 is heated and damaged by the magnetic field generated by the coils 200, even holes are formed, and the like can be effectively avoided, and the product quality is improved. Moreover, the disk seat 100 is connected through the middle keep-out area 230 of the coil 200, which is beneficial to improving the space utilization rate, thereby being beneficial to reducing the volume of the electromagnetic heating assembly and reducing the volume of the electromagnetic cooking appliance applying the electromagnetic heating assembly.

In a particular application, the magnetic core 400 is made of a soft magnetic ferrite material, such as a manganese-zinc-ferrite material.

In one particular embodiment, magnetic core 400 comprises a magnetic strip. Wherein, the magnetic stripe is used for strengthening alternating magnetic field's magnetism, because the magnetic stripe magnetic resistance is little, and air magnetic resistance is big, through setting up the magnetic stripe for magnetic field receives the influence of magnetic stripe, and whole enrichments are in magnetic stripe department, thereby can play the effect that changes magnetic field intensity and magnetic field direction, improve heating efficiency.

Example two:

on the basis of the first embodiment, each core holder 300 includes a connection area connected to the tray 100 and a core mounting area for mounting the core 400, and the connection area and the mounting area are disposed adjacently or at intervals.

In this embodiment, by using the area of each magnetic core holder 300 for connecting with the tray 100 as the connection area, using the area of each magnetic core holder 300 for installing the magnetic core 400 as the magnetic core installation area, and using the connection area and the magnetic core installation area to be adjacently distributed or distributed at intervals, i.e. not intersecting, it is possible to effectively prevent the installation of the magnetic core 400 from affecting the connection between the magnetic core holder 300 and the tray 100, and prevent the magnetic core 400 from shielding the middle keep-out area 230 of the coil 200, so that the magnetic core holder 300 cannot connect with the tray 100 through the middle keep-out area 230.

In a specific embodiment, as shown in fig. 7 and 8, it is further defined that each core holder 300 has two or more cores 400 thereon. The magnetic cores 400 are distributed at intervals at the central keep-out area 230 spanned by the magnetic core holder 300, that is, the plurality of magnetic cores 400 have gaps at the central keep-out area 230, and the magnetic core holder 300 is connected to the tray 100 through the gaps between the plurality of magnetic cores 400 and the central keep-out area 230. Because the magnetic field intensity at the gap positions of the magnetic cores 400 and the middle space avoidance area 230 of the coil 200 is weaker, the phenomena that the connecting piece of the magnetic core bracket 300 and the disk seat 100 is damaged by the heating of the magnetic field, even holes are formed, and the like can be effectively avoided, and the product quality is improved.

In addition, by distributing a plurality of magnetic cores 400 at two sides of the middle keep-out area 230, for example, by arranging two magnetic cores 400 on each magnetic core bracket 300, the two magnetic cores 400 are located at two opposite sides of the middle keep-out area 230 of the coil 200, which is beneficial for the two magnetic cores 400 to respectively correspond to a part of the coil 200, thereby enhancing the magnetic field intensity of the coil 200 acting on the pot body.

In a specific application, as shown in fig. 7 and 8, each core holder 300 has two cores 400, namely a first core 410 and a second core 420, and the first core 410 and the second core 420 are spaced apart from each other at a central keep-out area 230. At this time, each core holder 300 is coupled to the tray 100 through one of the middle keep-out areas 230. Of course, in the case that each core holder 300 is connected to the tray 100 through two middle keep-out areas 230, it is also possible to have three cores 400 on each core holder 300, and the three cores 400 are spaced apart at the two middle keep-out areas 230.

Of course, in other embodiments, one magnetic core 400 may be disposed on each magnetic core holder 300, as long as the connection region and the magnetic core mounting region do not overlap, for example, the magnetic core 400 is disposed on the magnetic core holder 300 to avoid the middle avoiding region 230, so that the magnetic core holder 300 can be connected to the tray 100 through the middle avoiding region 230 of the coil 200.

Further, the electromagnetic heating assembly further includes a first connecting member, and the first connecting member connects the core holder 300 and the tray 100 through the middle keep-out area 230.

In a specific embodiment, as shown in fig. 7 and 8, the first connection member includes a first threaded member 500, and the magnetic core holder 300 is connected to the tray 100 through the first threaded member 500, such as a screw or a bolt, and since the first threaded member 500 passes through the middle clearance area 230 to be connected to the tray 100, the first threaded member 500 is prevented from being heated by the magnetic field to be too high, and even from being perforated, while the installation stability of the magnetic core holder 300 is ensured.

Of course, other first connecting members, such as a buckle or a latch, may be used to connect the core holder 300 and the tray 100 instead of the first threaded member 500, and are not limited to the first threaded member 500, as long as the first connecting members are ensured to connect the core holder 300 and the tray 100 through the middle keep-out area 230.

Example three:

in addition to any of the above embodiments, as shown in fig. 3, 4 and 8, the tray 100 further includes a tray bottom portion 110, a tray side portion 130, and a tray transition portion 120 connecting the tray side portion 130 and the tray bottom portion 110.

In this embodiment, the tray 100 can provide support for the pan body. By arranging the tray transition part 120 between the tray bottom part 110 and the tray side part 130, the tray 100 has an attractive appearance as a whole, and the tray 100 can be adapted to the shape of the pot body, so that the pot body is well supported. Moreover, the coils 200 on the back of the tray 100 are beneficial to heating the pot body from the bottom and the side of the pot body, and the heating uniformity of food materials in the pot body is improved.

It is worth to be noted that the central axis of the pot body penetrates through the bottom of the pot, one end of the side part of the pot far away from the bottom of the pot forms a pot opening of the pot body, and a transition part is connected between the bottom of the pot and the side part of the pot. When the pot body is placed in the direction that the pot opening is upward, the wall surface of the pot side part is approximately vertical or slightly inclined, namely, the included angle between the wall surface of the pot side part and the horizontal plane is larger, and can be more than or equal to 60 degrees, for example. Except the side part of the pan, the rest part of the pan body forms a transition part and a pan bottom, the joint of the transition part and the pan bottom is the outer edge of the pan bottom and the inner edge of the transition part, and the joint of the transition part and the side part of the pan is the outer edge of the transition part. The shape of the pot bottom and the transition part can be different according to the specific design, in some embodiments, the pot bottom is approximately horizontal and can slightly protrude towards the inner part of the pot body, the transition part is connected between the approximately vertical pot side part and the approximately horizontal pot bottom and has larger bending, and the bending degree of the pot bottom and the transition part is obviously different. In other embodiments, the pan bottom may be a curved surface with a large curvature, such as a portion of a sphere, where the curvature of the pan bottom and the transition portion are similar without significant difference. Therefore, the division of the pot bottom and the transition part can be combined with the size of the pot bottom and the transition part in the horizontal direction. The distance between the outer edge of the pot bottom and the central axis of the pot body is d1, the distance between the outer edge of the transition part and the inner edge of the transition part in the horizontal direction is d2, and the ratio d1/d2 of the two can range from 7/10 to 10/7, i.e., d1 and d2 are close in value, d1 is greater than or equal to d2, and d2 is greater than or equal to d1, so as to ensure uniform transition. The distance between the outer edge and the inner edge of the pan side in the horizontal direction is related to the inclination degree of the wall surface of the pan side and the extension length of the pan side in the vertical direction, and is not limited herein. It can be understood that the tray bottom portion 110, the tray transition portion 120 and the tray side portion 130 of the tray base 100 correspond to the tray bottom portion, the transition portion and the tray side portion of the pan body, respectively, and it means that the tray bottom portion 110, the tray transition portion 120 and the tray side portion 130 correspond to the tray bottom portion, the transition portion and the tray side portion in the up-down direction, respectively, that is, a projection of the tray bottom portion 110 in the horizontal plane falls in a projection of the tray bottom portion in the horizontal plane, a projection of the tray transition portion 120 in the horizontal plane falls in a projection of the transition portion in the horizontal plane, and a projection of the tray side portion 130 in the horizontal plane falls in a projection of the tray side portion in the horizontal.

Further, as shown in fig. 3, 4, 5 and 8, at least two coils 200 are arranged to cover not only the pan bottom 110 of a part of the pan base 100 but also the pan side 130 of a part of the pan base 100, so that all the coils 200 of the electromagnetic cooking device can heat not only the food in the pot from the side of the pot but also the food in the pot from the bottom of the pot. The rolling frequency and the heating uniformity of the food materials in the pot body can be better increased by combining the interval distribution of all the coils 200, and the non-uniform maturity of the food materials in the pot body is avoided.

In a specific embodiment, as shown in fig. 3, 4 and 6, the electromagnetic cooking appliance includes at least two first coils 210, and each first coil 210 of the at least two first coils 210 can extend from the pan side portion 130 of the pan base 100 to the pan bottom portion 110 of the pan base 100, so that each first coil 210 can simultaneously heat the side wall of the pan body and the bottom wall of the pan body, which is beneficial to increasing the tumbling frequency and the heating uniformity of the food material inside the pan body, and is beneficial to uniformly heating the food material inside the pan body, thereby improving the cooking effect.

Further, as shown in fig. 3 and 4, the first coil 210 is enclosed by a middle evasive space 230 corresponding to the disk transition portion 120 of the disk seat 100. The disk transition portion 120 is disposed obliquely with respect to the central axis of the disk bottom 110, i.e., the middle keep-out area 230 is disposed obliquely with respect to the central axis of the disk bottom 110. Therefore, bubbles formed at the position corresponding to the empty avoiding area 230 in the middle of the first coil 210 can reach the middle of the pot body more easily, and can be flushed out of food at the middle of the pot body, and the heat brought out can enable the food at the middle of the pot body to be heated uniformly.

Further, all the first coils 210 of the electromagnetic cooking appliance are spaced around the central axis of the bottom portion 110 of the dish base 100. For example, all the first coils 210 are distributed at equal intervals, so that the pan body is fully and uniformly heated, and in combination with each first coil 210, the pan side portion 130 of the pan base 100 can extend to the pan bottom portion 110 of the pan base 100, which is beneficial to reducing the number of heating units, thereby reducing the production cost.

In another specific embodiment, as shown in fig. 5, the electromagnetic cooking appliance further includes a second coil 220. By arranging the second coil 220 at the tray bottom portion 110 of the tray 100, and combining with the two or more first coils 210 of the electromagnetic cooking appliance, which extend from the tray side portion 130 of the tray 100 to the tray bottom portion 110 of the tray 100, the food material in the pot body can be heated simultaneously by the first coils 210 and the second coil 220, so that the food material in the pot body can be heated better from the bottom and the side of the pot body, and the heating uniformity of the food material in the pot body is improved.

Further, the number of the second coils 220 is one, and the second coils 220 are disposed in the middle of the bottom plate portion 110. The uniformity of the food material heated in the bottom direction of the pot body is improved.

Further, the number of the second coils 220 is plural, and the second coils are spaced apart from each other at the bottom 110 of the disk. So that the bubbles can rise to the top of the food material from more positions, and the uniformity of heating from the food material in the bottom direction of the pot body is improved.

In one particular embodiment, as shown in fig. 7 and 8, each core support 300 is extended from the tray side 130 to the tray bottom 110 of the tray 100. Because the first coil 210 also extends from the disk side 130 of the disk seat 100 to the disk bottom 110, and the magnetic core support 300 spans the middle space-avoiding region 230 of the first coil 210, on the magnetic core support 300, the magnetic cores 400 distributed at the middle space-avoiding region 230 can respectively correspond to the disk side 130 of the disk seat 100 and the disk bottom 110 of the disk seat 100, so that the magnetic field intensity of the coil 200 acting on the pot body in the side direction and the bottom direction of the pot body is enhanced, and the heating effect is improved.

For example, as shown in fig. 7 and 8, each core holder 300 has two cores 400, namely a first core 410 and a second core 420, and all of the coils 200 are the first coils 210, so that each first coil 210 extends from the tray side portion 130 to the tray bottom portion 110 of the tray 100, and each core holder 300 also extends from the tray side portion 130 to the tray bottom portion 110 of the tray 100. Therefore, the first magnetic core 410 corresponds to the plate side portion 130 of the plate seat 100, and the second magnetic core 420 corresponds to the plate bottom portion 110 of the plate seat 100, so that the magnetic field intensity of the coil 200 acting on the pot body in the side direction and the bottom direction of the pot body can be enhanced, and the heating effect is improved.

For another example, if all of the coils 200 include the first coil 210 and the second coil 220, each of the core holders 300 may be connected to the tray 100 through the central keep-out region 230 of the first coil 210. At this time, the magnetic core 400 on each magnetic core holder 300 may correspond to only the first coil 210, or may correspond to the first coil 210 and the second coil 220, and at this time, the magnetic core holder 300 needs to extend to a side of the second coil 220 away from the tray 100. Of course, it is also possible to connect some of the core holders 300 to the tray 100 through the middle space-avoiding region 230 of the first coil 210, for example, to connect the first core holder to the tray 100 through the middle space-avoiding region 230 of the first coil 210, and to connect another core holder 300 to the tray 100 through the middle space-avoiding region 230 of the second coil 220, for example, to connect the second core holder to the tray 100 through the middle space-avoiding region 230 of the second coil 220.

Example four:

on the basis of any of the above embodiments, as shown in fig. 8, the coil 200 is further directly disposed on the surface of the tray 100 away from the accommodating cavity, so that the coil support 600 is eliminated, the number of parts is reduced, the cost is saved, and the size of the electromagnetic cooking appliance is reduced. Specifically, the coil 200 is wound and adhered to the tray 100, or the coil 200 is wound and adhered to the tray 100, and the coil 200 is fixed to the tray 100 in an adhering manner, so that the assembly is convenient and firm.

Of course, a winding portion can be further arranged on the surface of the disk seat 100 deviating from the accommodating cavity, so that the coil 200 is sleeved on the winding portion, and further the coil 200 is arranged on the disk seat 100, which is beneficial to improving the installation stability of the coil 200.

Example five:

in a fourth difference from the embodiment, as shown in fig. 6 and 7, a coil holder 600 is connected to the tray 100, and the coil 200 is disposed on the coil holder 600 to fix the coil 200, so as to prevent the coil 200 from falling off. In the case where the induction cooking appliance includes at least two coils 200, the assembly of the coils 200 to the susceptor 100 by the coil support 600 is facilitated, and the productivity can be improved, compared to the conventional process of processing the cake of the coils 200.

Moreover, the coil support 600 is connected with the tray 100 through the middle space-avoiding area 230 of the coil 200, and the magnetic field intensity of the middle space-avoiding area 230 of the coil 200 is weak, so that the phenomena that the connecting piece of the coil support 600 and the tray 100 is heated and damaged by the magnetic field generated by the coil 200, even a perforation occurs, and the like can be effectively avoided, and the product quality is improved. Moreover, the disk seat 100 is connected through the middle keep-out area 230 of the coil 200, which is beneficial to improving the space utilization rate, thereby being beneficial to reducing the volume of the electromagnetic heating assembly and reducing the volume of the electromagnetic cooking appliance applying the electromagnetic heating assembly.

In a specific embodiment, as shown in fig. 6 and 7, in the case that the coil holder 600 and the core holder 300 are coupled to the tray 100 through the same middle space-avoiding region 230, a mounting groove 610 is formed in the coil holder 600 at a position corresponding to the middle space-avoiding region 230, an opening 620 is formed in the mounting groove 610, and a portion of the core holder 300 can be inserted into the mounting groove 610 and coupled to the tray 100 through the opening 620. The installation groove 610 is beneficial to limiting the magnetic core bracket 300 and improving the installation firmness of the magnetic core bracket 300; on the other hand, the occupied space of the whole coil support 600 and the whole magnetic core support 300 is reduced, the space of the middle space avoiding area 230 is fully utilized, the connection between the coil support 600 and the magnetic core support 300 and the tray 100 is realized, the size of the electromagnetic heating assembly is reduced, and the size of the electromagnetic cooking appliance using the electromagnetic heating assembly is reduced.

In addition, in the case that the core holder 300 is stably coupled to the tray 100, since a portion of the core holder 300 is inserted into the mounting groove 610 and the opening 620 of the mounting groove 610 is necessarily located at a side of the coil holder 600 facing away from the tray 100, the core holder 300 can limit the coil holder 600 by the mounting groove 610, a bottom wall of the mounting groove 610, and the like. For example, it is advantageous to press the coil holder 600 against the tray 100 through the groove bottom wall of the mounting groove 610, thereby also contributing to the improvement of the mounting stability of the coil holder 600.

Further, the coil support 300 and the disk seat 100 are connected by the second connecting member, and the second connecting member is connected with the disk seat 100 through the middle space-avoiding region 230, so that the second connecting member can be effectively prevented from being heated by the magnetic field and being too high in temperature.

In a specific embodiment, as shown in fig. 7, the second connection member includes a second screw member 700, such that the coil support 600 and the tray 100 are connected by the second screw member 700, for example, a screw or a bolt, and since the second screw member 700 passes through the middle keep-out area 230 to be connected with the tray 100, the second screw member 700 is prevented from being heated by the magnetic field to be too high, and even from being perforated, while the stability of the installation of the coil support 600 is ensured.

Of course, other second connecting members, such as a snap or a latch, may be used to connect the coil support 600 and the tray 100 instead of the second screw member 700, and are not limited to the second screw member 700, as long as the second connecting members are ensured to connect the coil support 600 and the tray 100 through the middle keep-out area 230.

In a specific application, as shown in fig. 7, two second screws 700 are used to connect one coil support 600 to the tray 100. And the first screw member 500 connecting the core holder 300 and the tray 100 is positioned between the two second screw members 700, that is, the two second screw members 700 are disposed at opposite sides of the mounting groove 610.

Further, an avoidance notch is provided at one side or both sides in the width direction of the core holder 300. On the one hand, the second screw member 700 is provided with an avoiding space, and the second screw member 700 partially extends into the avoiding gap and the middle avoiding area 230 to be connected with the disk seat 100. Thereby the second screw 700 not only enables the coil support 600 to be stably connected on the disk seat 100, but also is beneficial to limiting the magnetic core support 300, and the installation stability of the magnetic core support 300 is improved. On the other hand, the material of the magnetic core bracket 300 is reduced, the cost is saved, and the weight of the magnetic core bracket 300 is reduced.

In a specific embodiment, as shown in fig. 3 and 4, at least two pairs of limiting members 140 are disposed on the tray 100, each pair of limiting members 140 limits one coil support 600, specifically, the pair of limiting members 140 is attached to a side wall of the mounting groove 610 of one coil support 600, and the mounting groove 610 is sandwiched between the pair of limiting members 140. On one hand, the coil support 600 is easy to install stably, and on the other hand, the coil support 600 is easy to align with each pair of the position-limiting members 140 and can be installed in place quickly.

In a specific application, the coil support 600 is partially recessed toward the tray 100 to form the mounting groove 610. The limiting member 140 is a limiting protrusion, and the limiting member 140 and the base 100 are integrally formed.

Example six:

an electromagnetic cooking appliance comprising: the electromagnetic heating assembly of any of the embodiments above.

The electromagnetic cooking appliance provided in this embodiment has the beneficial effects of any of the above embodiments due to the electromagnetic heating assembly provided in any of the above embodiments, which are not repeated herein.

Further, the electromagnetic cooking appliance further comprises a pot body for containing food materials. The pan body can be fixedly arranged in the accommodating cavity of the tray base 100, and can also be detachably connected with the tray base 100, so that the pan body can be conveniently taken out of the accommodating cavity of the tray base 100.

In a specific embodiment, the spacing between the at least two coils 200 and the pan body is further defined to be in a range of 2.5mm to 10 mm.

In this embodiment, the distance between the outer surface of the pot body and each coil 200 is between 2.5mm and 10mm, for example, the distance between the outer surface of the pot body and each coil 200 is 2.6mm, 4mm, 6mm, 8.6mm or 9.5mm, etc., and by reducing the working distance between the coil 200 and the pot, that is, reducing the distance between the coil 200 and the outer surface of the pot body, it is beneficial to increase the coupling parameter between each coil 200 and the pot body, thereby improving the electromagnetic induction heating conversion efficiency and improving the power and energy efficiency of the electromagnetic cooking appliance.

Specifically, as shown in fig. 1 and 2, the related art dish base is mostly bowl-shaped or arc-shaped. The coils 200' are each disposed at the tray bottom and the tray side of the tray, or at the tray transition between the tray bottom and the tray bottom wall and the tray side of the tray. According to the synchronous matching requirements of the coupling parameters of the coil 200 'and the pan body and the power and energy efficiency of the product, a larger working distance is formed between the coil 200' and the pan body. And this application specifically makes the quantity of coil 200 be at least two and interval distribution, and under the unchangeable condition of pot body size, the coupling parameter of the less coil 200 of this application and the pot body can be less, if coil 200 still keeps at great working distance with the pot body, can seriously influence electromagnetic cooking utensil's power and energy efficiency. And this application makes the working distance of pot body and every coil 200 between 2.5mm to 10mm specifically, is favorable to increasing the coupling parameter of every coil 200 and pot body to guarantee electromagnetic cooking utensil's power and energy efficiency.

In addition, the distance between the outer surface of the pot body and each coil 200 is larger than or equal to 2.5mm, so that the phenomenon that the distance between the coil 200 and the pot body is too close, the thickness of the tray seat 100 is too small, the structural strength of the tray seat 100 is influenced, and even the phenomenon that the heating area of the orthographic projection of the coil 200 onto the pot body is too high and local scorching occurs can be effectively avoided.

Further, the outer surface of the pan body is spaced the same distance as each coil 200. When the coil 200 heats the pan body, the pan body is beneficial to being heated evenly. Of course, in other embodiments, the outer surface of the pan body may be spaced differently from each coil 200, so long as the working spacing is maintained between 2.5mm and 10 mm.

Further, the outer contour of each coil 200 is circular or elliptical or polygonal, etc.
