Description

Technical Field

[0001] The present invention relates to the technical field of heating, and in particular, to an electromagnetic heating component and an electromagnetic heating device. Background Art

[0002] Electromagnetic heating has become a relatively mature heating technology at the present stage and is widely applied to electromagnetic heating devices such as induction cookers.

[0003] Among them, the working principle of the electromagnetic heating coil is as Figure 1 shown. After the electromagnetic heating coil is powered on, it will form a magnetic field provider with one end being the N pole and the other end being the S pole by itself. The magnetic force lines emitted from the N pole will pass through space and return to the S pole, thus forming a magnetic field. When the cookware is located in the magnetic field formed by the electromagnetic heating coil, eddy currents can be generated in the cookware itself, thereby generating heat. In order to enable the cookware to have a larger heating area and reduce the influence of the magnetic field on the interior of the device, it is necessary to promote the upward rise of the magnetic force lines emitted from the N pole and suppress the upward rise of the magnetic force lines of the S pole, that is, the upward rise height of the magnetic force lines emitted from the N pole should be higher than the upward rise height of the magnetic force lines returning to the S pole.

[0004] As Figure 2 and Figure 3 shown, when the electromagnetic heating coil is actually used, the electromagnetic heating coil 202' needs to be assembled onto the bracket 204', and the bracket 204' is fixed to the base 206' by screws to achieve heating of the cookware 208'.

[0005] However, the magnetic field generated by the electromagnetic heating coil has a heating distance, which is positively correlated with the upward rise height of the magnetic force lines emitted from the N pole. The size of the heating distance directly affects the heating effect of the cookware. Specifically, when the heating distance is large, the cookware will not stop heating due to the action of flipping the pan. On the contrary, when the heating distance is small, the cookware will stop heating due to the action of flipping the pan. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0007] To this end, the first aspect of the present invention is to provide an electromagnetic heating component.

[0008] The second aspect of the present invention is to provide an electromagnetic heating device.

[0009] In view of this, according to the first aspect of the present invention, the present invention provides an electromagnetic heating component, including: a first electromagnetic heating coil, the first electromagnetic heating coil includes at least two first coils arranged at intervals; a second electromagnetic heating coil, the second electromagnetic heating coil includes at least two second coils, the at least two second coils and the at least two first coils are arranged at intervals in sequence, and the stacking direction of the wire layers of the second coils is coplanar with the radial direction of the first coils.

[0010] The technical solution of the present invention proposes an electromagnetic heating component. In the above electromagnetic heating component, the stacking direction of the wire layers of the second coils is coplanar with the radial direction of the first coils. Therefore, the first coils and the second coils form a vertical and a horizontal installation state.

[0011] Based on this, after the first coils and the second coils are energized, the N pole formed by the first one of the at least two first coils will be close to the N pole formed by one of the first second coils after being energized. In the case where the N poles are close to each other, the two will form a repulsive force. Under the action of the above repulsive force, the magnetic field lines around the N pole of the first first coil and the magnetic field lines around the N pole of the first second coil will rise. The rising magnetic field lines will form a closed curve with the S pole of the first second coil.

[0012] At the same time, since the at least two second coils and the at least two first coils are arranged at intervals in sequence, therefore, the S pole formed by the second first coil adjacent to the first second coil will repel the S pole of the first second coil and the S pole of the second second coil, so that the magnetic field lines returning to the S pole formed by the second first coil can only return to the second first coil after rising. Obviously, whether it is the magnetic field lines emitted from the N pole of the first first coil or the magnetic field lines returning to the S pole of the second first coil, they are all subject to the rising effect. Therefore, compared with the related technical solutions, it can increase the rising distance of the magnetic field lines, thereby increasing the heating distance. At the same time, since the magnetic field lines formed by the N pole of the first second coil also rise synchronously, therefore, compared with the related technical solutions, the electromagnetic heating component proposed by the present invention can also increase the magnetic field intensity, increase the coverage range of the magnetic field, and improve the probability of the situation that the cooking utensil stops heating due to being far away from the first electromagnetic heating coil and the second electromagnetic heating coil in the scenario of flipping the pan.

[0013] In some technical solutions, the stacking direction of the wire of the first coil can be understood as the axial direction of the winding obtained by spirally winding the wire in the first coil. The definition of the stacking direction of the wire of the second coil is the same as that of the stacking direction of the wire of the first coil, and will not be elaborated here.

[0014] In some technical solutions, the direction in which the wire layers of the first coil are stacked can be understood as the direction from the S pole to the N pole of the first coil. Similarly, the definition of the direction in which the wire layers of the second coil are stacked is the same as that of the first coil, and will not be elaborated here.

[0015] In addition, the electromagnetic heating assembly proposed by the present invention also has the following additional technical features.

[0016] In some technical solutions, optionally, at least two of the second coils and at least two of the first coils are arranged at intervals in sequence to form a circular arrangement.

[0017] In this technical solution, by arranging at least two second coils and at least two first coils in a circular distribution, a heating surface with a relatively large area can be formed, thereby ensuring the heating effect.

[0018] In one of the technical solutions, at least two of the second coils and at least two of the first coils arranged in a circular pattern can form a circular heating surface, thereby adapting to the shape of the cookware.

[0019] In some technical solutions, optionally, the electromagnetic heating assembly further includes: a bracket, the bracket includes: at least two mounting barrels, which are arranged corresponding to at least two first coils and are used to accommodate the first coils or the first coils are sleeved on the mounting barrels; at least two winding parts, at least part of the winding parts are connected to at least part of the outer wall of the mounting barrel, and the winding parts are used to wind the second coils.

[0020] In this technical solution, by providing the mounting barrels and the winding parts to fix the relative positions between the first coil and the second coil, after assembling the first coil and the second coil onto the bracket, the bracket, the first electromagnetic heating coil and the second electromagnetic heating coil can be assembled as a whole, thereby reducing the complexity of the assembly and improving the assembly efficiency.

[0021] In addition, by providing the mounting barrels to provide a placement space for the first coil, during this process, the probability of the electromagnetic heating assembly becoming unusable due to the first coil moving out of its original position during the use of the electromagnetic heating assembly can be reduced, thereby improving the reliability of the electromagnetic heating assembly.

[0022] In the above technical solution, the provided winding parts can directly wind the second coils on the winding parts. While maintaining the attitude of the second coils after assembly, the second coils can be directly obtained by winding on the basis of the bracket. During this process, no secondary assembly is required, reducing the assembly process of the electromagnetic heating assembly, thereby improving the assembly efficiency.

[0023] In some technical solutions, optionally, the mounting barrels and the winding parts are of an integral structure.

[0024] In this technical solution, the number of accessories of the electromagnetic heating component can be reduced to lower the manufacturing difficulty of the bracket.

[0025] In some technical solutions, optionally, the bracket further includes: a first fixing portion provided on one or more of at least two winding portions, and the first fixing portion is used to fix the bracket to the base body.

[0026] In this technical solution, by providing the first fixing portion, the bracket can be fixed to the base body by using the first fixing portion, so as to prevent the electromagnetic heating component from shaking on the base body after being assembled to the base body, which affects the stability of the electromagnetic heating component.

[0027] In the above technical solution, the first fixing portion is provided on each of at least two winding portions. In this case, the bracket and the base body can be reliably fixed.

[0028] In the above technical solution, the number of the first fixing portions provided can be selected according to actual usage needs. In this process, while ensuring the reliable fixing between the bracket and the base body, a high assembly efficiency can be ensured.

[0029] In the above technical solution, by providing the first fixing portion on a non-target area of the winding portion, where the non-target area is the area on the winding portion except the target area, and the target area is the area for winding the second coil.

[0030] In some technical solutions, optionally, the material of the mounting barrel and / or the material of the winding portion is a high-temperature resistant material.

[0031] In some technical solutions, optionally, the material of the mounting barrel is a magnetic material; and / or the material of the winding portion is a magnetic material.

[0032] In this technical solution, when the material of the mounting barrel is a magnetic material, the mounting barrel can be used to enhance the magnetic field intensity of the N pole of the first coil, and at the same time, weaken the magnetic field intensity of the S pole of the first coil, thereby increasing the upward degree of the magnetic force lines emitted by the N pole of the first coil and increasing the heating efficiency of the electromagnetic heating.

[0033] In addition, when the winding portion is a magnetic material, the winding portion can be used to enhance the magnetic field intensity of the N pole of the second coil, and at the same time, weaken the magnetic field intensity of the S pole of the second coil, thereby increasing the upward degree of the magnetic force lines emitted by the N pole of the second coil and increasing the heating efficiency of the electromagnetic heating.

[0034] In some technical solutions, optionally, the electromagnetic heating component further includes: a magnetic core provided in the mounting barrel, and the first coil is sleeved on the magnetic core.

[0035] In this technical solution, a magnetic core is provided to enhance the magnetic field intensity at the N pole and S pole of the first coil by using the magnetic core, thereby enhancing the heating effect of the electromagnetic heating component.

[0036] In one of the technical solutions, the material of the magnetic core is a magnetic material, such as manganese-zinc ferrite material and / or nanocrystalline material.

[0037] In some technical solutions, optionally, the first coil is one of a spiral coil and a concentric circle coil; and / or the second coil is one of a spiral coil and a concentric circle coil.

[0038] In this technical solution, by defining the first coil and the second coil as a spiral coil or a concentric circle coil, the magnetic field intensity of the electromagnetic heating component is increased by increasing the number of coils, thereby increasing the heating power.

[0039] According to the second aspect of the present invention, the present invention provides an electromagnetic heating device, including: an electromagnetic heating component as described in any one of the above.

[0040] In some technical solutions, optionally, it further includes: a panel; a base body, an accommodation cavity is formed between the base body and the panel, and the electromagnetic heating component is disposed in the accommodation cavity.

[0041] In this technical solution, by providing the panel and the base body, the panel and the base body are used to enclose and form an accommodation cavity for accommodating the electromagnetic heating component, and then the electromagnetic heating component is assembled into the accommodation cavity to avoid direct exposure of the electromagnetic heating component for use, thereby eliminating the safety hazards of the electromagnetic heating device and ensuring the safe use of the electromagnetic heating device.

[0042] In some technical solutions, optionally, the panel can be understood as a support for placing cookware, and its manifestations in different types of electromagnetic heating devices are different.

[0043] Exemplarily, in the case where the electromagnetic heating device is an induction cooker, the panel can be a ceramic glass.

[0044] Exemplarily, in the case where the electromagnetic heating device is a rice cooker and an electric pressure cooker, the panel can be a support, where the support can be understood as a structure for accommodating cookware.

[0045] In some technical solutions, optionally, the base body is further provided with: a second fixing portion; in the case where the bracket in the electromagnetic heating component includes a first fixing portion, the second fixing portion cooperates with the first fixing portion to fix the bracket on the base body.

[0046] In this technical solution, by providing a second fixing portion on the seat body, the second fixing portion can cooperate with the first fixing portion, thereby fixing the bracket in the electromagnetic heating component on the base, reducing the shaking of the electromagnetic heating component in the accommodation cavity, and improving the working reliability of the electromagnetic heating device in this way.

[0047] In some technical solutions, optionally, the electromagnetic heating device includes one of the following: an induction cooker, an electric stove, a rice cooker, and an electric pressure cooker.

Detailed implementation manners

[0068] In order to be able to more clearly understand the above aspects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0069] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0070] In one embodiment of the present application, as Figure 4 , Figure 5 , Figure 9 , Figure 10 and Figure 11As shown in the figure, an electromagnetic heating component is provided, including: a first electromagnetic heating coil 402, the first electromagnetic heating coil 402 includes at least two first coils 4022 arranged at intervals; a second electromagnetic heating coil 404, the second electromagnetic heating coil 404 includes at least two second coils 4042, at least two second coils 4042 and at least two first coils 4022 are arranged at intervals in sequence, and the stacking direction of the wire layers of the second coils 4042 is coplanar with the radial direction of the first coils 4022.

[0071] An embodiment of the present invention provides an electromagnetic heating component. In the above electromagnetic heating component, the stacking direction of the wire layers of the second coils 4042 is coplanar with the radial direction of the first coils 4022. Therefore, the first coils 4022 and the second coils 4042 form a vertical and a horizontal installation state.

[0072] Based on this, after the first coils 4022 and the second coils 4042 are energized, the N pole formed by the first one of the at least two first coils 4022 will be close to the N pole formed by one of the first second coils 4042 after being energized. In the case where the N poles are close to each other, the two will form a repulsive force. Under the action of the above repulsive force, the magnetic field lines around the N pole of the first first coil 4022 and the magnetic field lines around the N pole of the first second coil 4042 will rise. The rising magnetic field lines will form a closed curve with the S pole of the first second coil 4042.

[0073] At the same time, since at least two second coils 4042 and at least two first coils 4022 are arranged at intervals in sequence, therefore, the S pole formed by the second first coil 4022 adjacent to the first second coil 4042 will repel the S pole of the first second coil 4042 and the S pole of the second second coil 4042, so that the magnetic field lines returning to the S pole formed by the second first coil 4022 can only return to the second first coil 4022 after rising. Obviously, whether it is the magnetic field lines emitted from the N pole of the first first coil 4022 or the magnetic field lines returning to the S pole of the second first coil 4022, they are all subject to the rising effect. Therefore, compared with the related embodiments, the rising distance of the magnetic field lines can be increased, thereby increasing the heating distance. At the same time, since the magnetic field lines formed by the N pole of the first second coil 4042 also rise synchronously, therefore, compared with the related embodiments, the electromagnetic heating component proposed by the present invention can also increase the magnetic field intensity, increase the coverage range of the magnetic field, and improve the probability of the situation that the cooking pot 500 stops heating due to being far away from the first electromagnetic heating coil 402 and the second electromagnetic heating coil 404 in the scenario of flipping the pot.

[0074] In addition, when increasing the coverage of the magnetic field, more sides of the cookware are also within the coverage of the magnetic field. On this basis, the area where eddy currents appear in the cookware also increases synchronously, achieving three-dimensional heating of the food materials to improve the heating effect.

[0075] In some embodiments, the stacking direction of the wires of the first coil 4022 can be understood as the axial direction of the winding obtained after the wires of the first coil 4022 are spirally wound. The definition of the stacking direction of the wires of the second coil 4042 is the same as that of the stacking direction of the wires of the first coil 4022, and will not be elaborated here.

[0076] In some embodiments, the stacking direction of the wires of the first coil 4022 can be understood as the direction from the S pole to the N pole of the first coil 4022. Similarly, the definition of the stacking direction of the wires of the second coil 4042 is the same as that of the stacking direction of the wires of the first coil 4022, and will not be elaborated here.

[0077] In one of the embodiments, as Figure 4 and Figure 5 shown, the number of the first coils 4022 is two, and the number of the second coils 4042 is two. Then, the N poles of the two second coils 4042 face the same direction, and the N poles of the two first coils 4022 face opposite directions.

[0078] Based on this, the distribution of the N poles and S poles of the two first coils 4022 and the two second coils 4042 is as Figure 6 shown, where the magnetic field of the N pole and the magnetic field of the S pole are strengthened.

[0079] Specifically, as Figure 7 shown, when multiple magnetic bodies are arranged in the manner as Figure 7 shown, the magnetic force lines above the magnetic bodies rise, while the magnetic force lines below the magnetic bodies quickly form closed curves. Based on this, as Figure 8 shown, when the first electromagnetic heating coil 402 includes four first coils 4022 and the second electromagnetic heating coil 404 includes four second coils 4042, it can form a magnetic field distribution state as Figure 7 shown.

[0080] Specifically, as Figure 9 , Figure 10 and Figure 11 shown, the number of the first coils 4022 is four, and the number of the second coils 4042 is four. Then, the N poles of two of the four first coils 4022 face the same direction, and are opposite to the N poles of the other two first coils 4022 among the four first coils 4022.

[0081] In some embodiments, optionally, at least two of the second coils 4042 and at least two of the first coils 4022 are arranged at intervals in sequence to form a circular arrangement.

[0082] In this technical solution, by arranging at least two second coils 4042 and at least two first coils 4022 in a circular distribution, a heating surface with a relatively large area can be formed, thereby ensuring the heating effect.

[0083] In one of the technical solutions, at least two of the second coils 4042 and at least two of the first coils 4022 arranged in a circular pattern can form a circular heating surface, thereby adapting to the shape of the cookware.

[0084] In some embodiments, optionally, as Figure 11 、 Figure 12 and Figure 13 shown, the electromagnetic heating assembly further includes: a bracket 406, the bracket 406 includes: at least two mounting barrels 4062, corresponding to at least two first coils 4022, for accommodating the first coils 4022 or the first coils 4022 are sleeved on the mounting barrels 4062; at least two winding parts 4064, at least part of the winding parts 4064 are connected to at least part of the outer wall of the mounting barrel 4062, and the winding parts 4064 are used for winding the second coils 4042.

[0085] In this embodiment, by providing the mounting barrels 4062 and the winding parts 4064 to fix the relative positions between the first coils 4022 and the second coils 4042, after assembling the first coils 4022 and the second coils 4042 onto the bracket 406, the bracket 406, the first electromagnetic heating coils 402 and the second electromagnetic heating coils 404 can be assembled as a whole, thereby reducing the complexity of the assembly and improving the assembly efficiency.

[0086] In addition, by providing the mounting barrels 4062 to provide a placement space for the first coils 4022, during this process, the probability of the electromagnetic heating assembly becoming unusable due to the first coils 4022 deviating from their original positions during the use of the electromagnetic heating assembly can be reduced, thereby improving the reliability of the electromagnetic heating assembly.

[0087] In the above embodiment, the provided winding parts 4064 can directly wind the second coils 4042 on the winding parts 4064. While maintaining the posture of the second coils 4042 after assembly, the second coils 4042 can be directly obtained by winding on the basis of the bracket 406. During this process, no secondary assembly is required, reducing the assembly process of the electromagnetic heating assembly, thereby improving the assembly efficiency.

[0088] In some embodiments, optionally, the mounting barrel 4062 and the winding portion 4064 are of an integral structure.

[0089] In this embodiment, the number of components of the electromagnetic heating assembly can be reduced to facilitate reducing the manufacturing difficulty of the bracket 406.

[0090] In some embodiments, optionally, as Figure 12 and Figure 13 shown, the bracket 406 further includes: a first fixing portion 408 provided on one or more of at least two winding portions 4064, and the first fixing portion 408 is used to fix the bracket 406 to the seat body 700.

[0091] In this embodiment, by providing the first fixing portion 408, the bracket 406 can be fixed to the seat body 700 by using the first fixing portion 408, so as to prevent the electromagnetic heating assembly from shaking on the seat body 700 after being assembled to the seat body 700, which affects the stability of the electromagnetic heating assembly.

[0092] In the above embodiment, the first fixing portion 408 is provided on each of at least two winding portions 4064. In this case, the bracket 406 and the seat body 700 can be reliably fixed.

[0093] In the above embodiment, the number of the first fixing portions 408 can be selected according to actual usage needs. In this process, while ensuring the reliable fixing between the bracket 406 and the seat body 700, a high assembly efficiency can be ensured.

[0094] In the above embodiment, by arranging the first fixing portion 408 in a non-target area on the winding portion 4064, where the non-target area is the area on the winding portion 4064 other than the target area, and the target area is the area for winding the second coil 4042.

[0095] In some embodiments, optionally, the material of the mounting barrel 4062 and / or the material of the winding portion 4064 is a high-temperature resistant material.

[0096] In some embodiments, optionally, the material of the mounting barrel 4062 is a magnetic material; and / or the material of the winding portion 4064 is a magnetic material.

[0097] In this embodiment, when the material of the mounting barrel 4062 is a magnetic material, the magnetic field intensity of the N pole of the first coil 4022 can be enhanced by using the mounting barrel 4062. At the same time, the magnetic field intensity of the S pole of the first coil 4022 is weakened, thereby increasing the upward degree of the magnetic force lines emitted by the N pole of the first coil 4022 and increasing the heating efficiency of the electromagnetic heating.

[0098] In addition, the winding part 4064 is made of a magnetic material, and the winding part 4064 can be used to enhance the magnetic field strength of the N pole of the second coil 4042. At the same time, the magnetic field strength of the S pole of the second coil 4042 is weakened, thereby increasing the upward degree of the magnetic force lines emitted by the N pole of the second coil 4042 and increasing the heating efficiency of the electromagnetic heating.

[0099] In some embodiments, optionally, as Figure 11 shown, the electromagnetic heating assembly further includes: a magnetic core 410 disposed in the mounting barrel 4062, and the first coil 4022 is sleeved on the magnetic core 410.

[0100] In this embodiment, by providing the magnetic core 410, the magnetic field strength at the N pole and the S pole of the first coil 4022 can be utilized to enhance the heating effect of the electromagnetic heating assembly.

[0101] In one of the embodiments, the material of the magnetic core 410 is a magnetic material, such as manganese-zinc ferrite material and / or nanocrystalline material.

[0102] In some embodiments, optionally, the first coil 4022 is one of a spiral coil and a concentric circle coil; and / or the second coil 4042 is one of a spiral coil and a concentric circle coil.

[0103] In this embodiment, by defining the first coil 4022 and the second coil 4042 as spiral coils or concentric circle coils, the magnetic field strength of the electromagnetic heating assembly can be increased by increasing the number of coils, thereby increasing the heating power.

[0106] In this embodiment, by providing the panel 600 and the base 700, the panel 600 and the base 700 can be used to enclose and form an accommodation cavity 800 for accommodating the electromagnetic heating assembly, and then the electromagnetic heating assembly is assembled into the accommodation cavity 800 to avoid direct exposure of the electromagnetic heating assembly for use, thereby eliminating the safety hazards of the electromagnetic heating device and ensuring the safe use of the electromagnetic heating device.

[0107] In some embodiments, optionally, the panel 600 can be understood as a support for placing the cookware 500, and its manifestations in different types of electromagnetic heating devices are different.

[0111] In this embodiment, by providing the second fixing portion 702 on the base 700, so that the second fixing portion 702 can cooperate with the first fixing portion 408, and further fix the bracket 406 in the electromagnetic heating assembly on the base, reducing the shaking of the electromagnetic heating assembly in the accommodating cavity 800, thereby improving the working reliability of the electromagnetic heating device.
