And the partition through grooves 116, the boss through grooves 41 and the side edge through grooves 30 are defined to be corresponding and mutually communicated to form a plurality of heat dissipation air channels on the coil panel 100, so that the arrangement can ensure that the heat dissipation air flow flowing through the side edge through grooves 30 further flows to the central position close to the coil panel 100 through the boss through grooves 41 and the partition through grooves 116, and the heat dissipation effect of the heat dissipation air flow on the coil panel 100 is improved.

Wherein, the cross-sectional area of at least part of the heat dissipation air duct is gradually reduced from one side close to the edge position of the coil panel 100 to one side close to the center position of the coil panel 100.

In an implementation, the partition 112 includes a plurality of first partitions disposed between the bosses 40 and the edge positions of the coil disk 100, the plurality of partition through slots 116 are located on the first partitions, and the side edge through slots 30, the partition through slots 116, and the boss through slots 41 form a first heat dissipation air duct. The cross-sectional area of the first heat dissipation air duct gradually decreases from the side close to the edge of the coil panel 100 to the side close to the center of the coil panel 100. It should be noted that, one end of the first heat dissipation air duct is formed by the lateral edge through groove 30, and the lateral edge through groove 30 is communicated with the outside, so that it can be ensured that external heat dissipation air flows into the coil disc 100, and the heat dissipation is performed on the structural member located in the first heat dissipation air duct inside the coil disc 100. Meanwhile, the cross-sectional area of the first heat dissipation air duct is gradually reduced, which can ensure that the flow velocity of the heat dissipation air flowing in the coil disc 100 is increased, thereby improving the heat dissipation effect of the heat dissipation air duct.

The cross-sectional area of the second heat dissipation air duct gradually decreases from the side close to the edge of the coil panel 100 to the side close to the center of the coil panel 100. It should be noted that the second heat dissipation air duct is communicated with the first heat dissipation air duct through the boss through groove 41, and the heat dissipation air flow in the first heat dissipation air duct flows into the second heat dissipation air duct, so as to dissipate heat of the structural member near the center of the coil panel 100. Meanwhile, the cross-sectional area of the second heat dissipation air duct is gradually reduced, which can ensure that the flow velocity of the heat dissipation air flowing in the coil disc 100 is increased, thereby improving the heat dissipation effect of the heat dissipation air duct.

Feasible is, be provided with at least one louvre on the support body 11, this louvre can set up the position that does not set up winding groove 113 and magnetic stripe mounting groove 114 on the support body 11, avoids producing the influence to setting up between them, and this louvre can communicate the heat dissipation wind channel, and the heat dissipation wind current in the heat dissipation wind channel of being convenient for flows support body 11 to improve support body 11's radiating effect.

Specifically, both ends of the side edge 111 extend toward the side close to the coil 50 and the side away from the coil 50, respectively, and the side edge through groove 30 is located on the side edge 111 close to the coil 50 and the side away from the coil 50. It should be noted that the two ends of the side edge 111 can respectively protect the surfaces of the coil panel 100 close to and far from the coil 50 and the structural members on the two surfaces, thereby improving the structural stability of the coil panel 100.

Referring to fig. 5, there are a plurality of side edge through grooves 30, and the plurality of side edge through grooves 30 are provided at intervals in the circumferential direction of the side edge 111. It should be noted that, when the heat dissipation wind flows through the side wall of the coil panel 100, the circular arc-shaped outer periphery of the coil panel 100 is extended to flow, so that the side edge through grooves 30 are provided in plurality and are spaced along the circumferential direction of the coil panel 100, and the heat dissipation wind flowing through the outer periphery of the coil panel 100 can enter the inner side of the side edge 111 of the coil panel 100 through the side edge through grooves 30, thereby dissipating heat inside the coil panel 100.

Further, the lateral edge through grooves 30 are provided in a plurality of numbers, so that it can be ensured that the partial lateral edge through grooves 30 supply the heat dissipation airflow to enter the lateral edge 111 of the coil panel 100, and the other part can ensure that the heat dissipation airflow after heat exchange with the coil panel 100 can timely flow out of the inside of the coil panel 100, so that the heat inside the coil panel 100 is taken away to reduce the temperature rise of the coil panel 100.

The researchers of this application found in the research process that under the same working condition and test condition, the actual measurement temperature of the coil panel 100 without the lateral edge through groove 30 was 136 ℃, and its corresponding temperature rise was 111 ℃. Whereas the measured temperature of the coil disk 100 provided with the side edge through slots 30 is 117 deg.c, which corresponds to a temperature rise of 92 deg.c. It can be seen that the opening of the side edge through slot 30 helps to reduce the temperature rise of the coil panel 100, and maintain the stability, safety and efficiency of the coil panel 100.

Specifically, referring to fig. 10, the side-edge through slot 30 is provided with a first guiding portion, which may be a slot side wall 30a of the side-edge through slot 30, the slot width of the side-edge through slot 30 gradually decreases from the slot opening of the side-edge through slot 30 to the slot bottom 30b, and an included angle between a plane of the slot side wall 30a of the side-edge through slot 30 and a plane of the slot bottom 30b of the side-edge through slot 30 is 90-150 °. It should be noted that the arrangement of the groove width of the lateral edge through groove 30 can effectively reduce the grooving difficulty of the lateral edge through groove 30, and simultaneously reduce the blocking of the groove wall of the lateral edge through groove 30 to the cooling air flow, thereby increasing the flow rate and the flow velocity of the cooling air flow passing through the lateral edge through groove 30. The cross section of the side edge through groove 30 along the flowing direction of the cooling wind flow may be a trapezoid or an isosceles trapezoid shown in fig. 10, and in practical use, the cross section of the side edge through groove 30 may also be a triangle or an arc, which is not limited in this embodiment. Wherein the angle between the plane of the groove sidewall 30a of the side edge through groove 30 and the plane of the groove bottom 30b of the side edge through groove 30 may be a portion shown by β in fig. 10. If the included angle between the groove side wall 30a of the lateral edge through groove 30 and the groove bottom 30b is too small, the blocking effect of the lateral edge through groove 30 on the heat dissipation air flow is too large, and the heat dissipation air flow is not facilitated to pass through; if the included angle between the groove sidewall 30a and the groove bottom 30b of the side edge through groove 30 is too large, the setting of the magnetic stripe installation groove 114 on the bracket body 11 will be affected, so in practical use, a user can select a specific value of the included angle within the above range according to needs, which is not limited in this embodiment.

Specifically, as shown in fig. 4 to 6, the slot width of the side-edge through slot 30 gradually decreases from the side near the edge position of the coil disk 100 to the side near the center position of the coil disk 100. With the arrangement, when the heat dissipation wind flows through the lateral edge through groove 30, the cross-sectional area of the flowing area is gradually reduced, and the groove lateral wall 30a of the lateral edge through groove 30 limits the heat dissipation wind flow, so that the flow speed of the heat dissipation wind flow is increased, and the heat dissipation effect of the heat dissipation wind flow on structural members including the coil 50 in the coil panel 100 is enhanced.

As an achievable embodiment, the side edge through slots 30 have a slot width in the range of 5-75 mm. The width of the side edge through groove 30 may be a portion shown in a in fig. 10, and based on that the setting of the magnetic stripe installation groove 114 is affected when the width of the side edge through groove 30 is too large, and when the width of the side edge through groove 30 is too small, the flow rate of the heat dissipation wind flow entering the inner side of the coil disc 100 is reduced, so in actual use, a user may select a specific value of the width of the side edge through groove 30 within the above range as required, and this embodiment does not limit this.

As an achievable embodiment, the width of the side edge 111 has a minimum value in the range 1-8 mm. The width of the side edge 111 may be the smallest value, which is shown as b in fig. 10. If the minimum width is too small, the strength of the side edge 111 of the bracket body 11 is poor, which affects the stability of the use of the bracket body 11, and if the minimum width is too large, the area of the opening region of the side edge through groove 30 is reduced, which affects the flow rate of the heat dissipation wind flow entering the inner side of the coil disc 100.

Referring to fig. 6, the side edge 111 includes a first side edge section 111a on the side of the holder body 11 close to the coil 50, and a second side edge section 111b on the side of the holder body 11 far from the coil 50. The side edge channel 30 comprises at least one first side edge channel 31 on the first side edge section 111a and/or at least one second side edge channel 32 on the second side edge section 111 b.

Specifically, the side edge channel 30 includes a first side edge channel 31, and a bottom of the first side edge channel 31 is lower than an upper surface of the coil 50. The first side edge through groove 31 can ensure that the heat dissipation wind flow outside the coil panel 100 contacts the coil 50, thereby improving the heat dissipation effect on the coil 50. As an achievable embodiment, the spacing between the slot bottom of the first side edge channel 31 and the upper surface of the coil 50 is in the range of 1-10 mm. This spacing may be a portion shown in c in fig. 10, and when the spacing is too small, the area of the effective flowing region of the heat dissipation wind flow in the first side edge through groove 31 is reduced, and the heat dissipation wind flow is not facilitated to enter the coil disc 100; when the distance is too large, the mechanical strength of the bracket body 11 is reduced, so that in practical use, a user can select a specific value of the distance within the above range according to needs, which is not limited in this embodiment.

Specifically, the side edge channel 30 includes a second side edge channel 32, and the bottom of the second side edge channel 32 is lower than the top surface of the magnetic strip 20. The second side edge through groove 32 can ensure that the heat dissipation wind flow outside the coil panel 100 contacts the magnetic strip 20, thereby improving the heat dissipation effect on the magnetic strip 20.

Specifically, the lateral edge through groove 30 includes a first lateral edge through groove 31 and a second lateral edge through groove 32, and a magnetic stripe mounting groove 114 is further arranged based on the lateral edge 111, so that the first lateral edge through groove 31 and the second lateral edge through groove 32 can be arranged to be staggered or arranged relatively to each other for adapting to the structure of the magnetic stripe mounting groove 114, thereby improving the flexibility and adaptability of the lateral edge through groove 30 structure.

In view of the high temperature problem at the center of the coil disc 100, the present embodiment provides a center region at the center of the coil disc 100, i.e. the center is not provided with a coil. This central zone can be used for setting up detection device, temperature-detecting device for example to the operating temperature in heating temperature or the coil panel 100 to the cooking pot carries out real time monitoring, and the electromagnetic cooking device of being convenient for adjusts the heating state of coil panel 100 according to this temperature-detecting device's testing result, realizes electromagnetic cooking device's accurate accuse temperature. Of course, in practical use, the type of the detecting device may be determined according to the user's selection, and the embodiment is not limited to this, and is not limited to the above example.

Wherein, the radius of the central region may be a portion shown by L1 in fig. 8, the width of the inner loop coil 51 may be a portion shown by L2 in the figure, the width of the spacing region may be a portion shown by L3, and the width of the outer loop coil 52 may be a portion shown by L4. The radius of the coil disc 100 may be the portion shown at L0. As an achievable embodiment, the ratio of L1 to L0 may range from 14% to 34%, the ratio of L2 to L0 may range from 32% to 52%, the ratio of L3 to L0 may range from 5% to 25%, and the ratio of L4 to L0 may range from 9% to 29%.

As an implementation manner, the inner loop coil 51 and the outer loop coil 52 may be connected in parallel or in series, or may be connected to the power supply device separately, and the connection manner of the two is not limited in this embodiment. Taking the two parallel connection as an example, referring to fig. 3, the coil 50 may be electrically connected to an external power supply device through a lead 60, where the lead 60 may include an inner loop incoming line 61 and an inner loop outgoing line 62 of the inner loop coil 51, and an outer loop incoming line 63 and an outer loop outgoing line 64 of the outer loop coil 52. The inner ring incoming line 61 and the outer ring incoming line 63 can be combined to form an incoming line, the two incoming lines are connected to the power supply device through the wiring terminal 90 at the end portion after being electrically connected, the inner ring outgoing line 62 and the outer ring outgoing line 64 can be combined to form an outgoing line, and the two incoming lines are connected to the power supply device through the wiring terminal 90 at the end portion after being electrically connected. The holder body 11 is further provided with a plurality of fasteners 115 for fixing the lead 60.

In order to improve the stability of the lead 60 in use, an electrically insulating sleeve 70 may be disposed outside at least a portion of the lead 60 to prevent the lead 60 from rubbing against external structural members, so as to prevent short circuit caused by the exposed inner wires after the lead 60 is worn, and optimize the protection effect of the lead 60. The specific location of the sleeve 70 can be set according to the requirement, which is not limited in this embodiment. Meanwhile, the heat shrinkable tube 80 may be sleeved at the electrical connection between the inner ring incoming line 61 and the outer ring incoming line 63, and/or the electrical connection between the inner ring outgoing line 62 and the outer ring outgoing line 64, so as to ensure the stability of the electrical connection position in the lead 60.

Similar to the side edge through groove 30, the boss through groove 41 is located in the gap 23 on the bracket body 11, such an arrangement can reduce the influence of the boss through groove 41 on the magnetic stripe 20, and the heat dissipation airflow flowing through the boss through groove 41 can dissipate the heat of the magnetic stripe 20.

Of course, the plurality of boss through grooves 41 may be provided, and the plurality of boss through grooves 41 are provided at intervals along the circumferential direction of the coil panel 100, so that the flow rate of the heat dissipation airflow flowing through the boss through grooves 41 can be increased, the flow rate of the heat dissipation airflow entering the center position of the coil panel 100 is increased, and the heat dissipation effect of the coil panel 100 is increased.

Wherein, be provided with first lateral margin logical groove 31 on the first lateral margin section 111a, first lateral margin logical groove 31 sets up with the logical groove 41 of boss relatively. With such arrangement, the heat dissipation wind current outside the coil panel 100 smoothly flows through the first side edge through groove 31, then directly continues to flow through the boss through groove 41, and then flows to the center position of the coil panel 100, thereby improving the heat dissipation effect of the coil panel 100. If the first side edge through groove 31 and the boss through groove 41 are staggered with each other, the heat dissipation wind flowing through the first side edge through groove 31 is blocked by the boss 40 when flowing to the center of the coil panel 100, and flows through the boss through groove 41 only after the flowing direction needs to be adjusted, so that the flow rate and the flow velocity of the heat dissipation wind flow are greatly reduced, and the vortex of the heat dissipation wind flow is formed in the coil panel 100, which is not beneficial to the heat dissipation of the coil panel 100.

Similar to the side edge through groove 30, the boss through groove 41 is provided with a second guiding portion, which may be a groove side wall of the boss through groove 41, the groove width of the boss through groove 41 is gradually reduced from the groove opening of the boss through groove 41 to the groove bottom, and an included angle between a plane where the groove side wall of the boss through groove 41 is located and a plane where the groove bottom of the boss through groove 41 is located ranges from 90 ° to 150 °. The groove width of the boss through groove 41 can effectively reduce the grooving difficulty of the boss through groove 41, and meanwhile, the blocking of the groove wall of the boss through groove 41 to the heat dissipation wind flow is reduced, so that the flow and the flow speed of the heat dissipation wind flow passing through the boss through groove 41 are increased. The shape of the boss through slot 41 may be the same as the shape of the first side edge through slot 31. If the included angle between the groove side wall of the boss through groove 41 and the groove bottom is too small, the blocking effect of the groove side wall of the boss through groove 41 on the heat dissipation air flow is too large, and the heat dissipation air flow is not facilitated to pass through; if the included angle between the groove sidewall of the through groove 41 and the groove bottom of the boss is too large, the setting of the magnetic stripe installation groove 114 on the bracket body 11 is affected, so in practical use, a user can select a specific value of the included angle within the above range according to needs, and the embodiment does not limit the included angle.

The slot width of the boss through slot 41 gradually decreases from the side close to the edge of the coil panel 100 to the side close to the center of the coil panel 100. Due to the arrangement, when the heat dissipation wind flows through the boss through groove 41, the cross-sectional area of the flowing area is gradually reduced, and the side wall of the boss through groove 41 limits the heat dissipation wind flow, so that the flow speed of the heat dissipation wind flow is increased, and the heat dissipation effect of the heat dissipation wind flow on structural members including the coil 50 in the coil panel 100 is enhanced.

Referring to fig. 7, the central angle of the skirt through groove 30 on the skirt 111 is a first central angle, the central angle of the boss through groove 41 on the boss 40 is a second central angle, the first central angle is equal to the second central angle, and the first central angle and the second central angle range from 10 ° to 65 °. It should be noted that the corresponding central angle of the skirt through slot 30 on the skirt 111 can be understood as: the side edge through groove 30 occupies the central angle corresponding to the arc section on the side edge 111, and the boss through groove 41 is similar to the central angle, and is not described in detail herein. The corresponding central angle of the skirt channel 30 on the skirt 111 and the corresponding central angle of the boss channel 41 on the boss 40 may be the portion shown as α in fig. 7. The first central angle and the second central angle are equal, and resistance of the heat dissipation wind flow when flowing inside the coil disk 100 can be reduced, so that the flow rate of the heat dissipation wind flow is increased, and the heat dissipation effect is improved. And when the values of the two are too large, the setting of the magnetic stripe installation slot 114 is affected, and when the values of the two are too small, the flow rate of the heat dissipation wind flow inside the coil panel 100 is reduced, so in actual use, a user can select specific values of the first central angle and the second central angle within the above range as required, which is not limited in this embodiment.
