Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions according to the embodiments of the present application with reference to the accompanying drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides a heating module 100 and an electrical device 200 provided with the heating module 100. The electric appliance 200 is a device for heating a cooker placed above the electric appliance 200 based on electromagnetic induction phenomenon, for example, the electric appliance 200 may be a full range multi-burner range, an induction cooker, or the like. The structure of the electric device 200 will be described herein by taking a full-area multi-burner range as an example.

Referring to fig. 1, an electrical apparatus 200 may include a housing 210, a functional panel 230, and the heating module 100 described above. The functional panel 230 is disposed on an outer surface of the housing 210, and is configured to receive a control operation of a user, and the heating module 100 is disposed inside the housing 210 and electrically connected to the functional panel 230, so as to perform a work according to the control operation received by the functional panel 230, where the control operation may include an opening operation, a timing operation, a heating mode selection operation, and so on.

In some possible embodiments, the housing 210 may include a first housing portion (not shown in the drawings) and a second housing portion (not shown in the drawings), where the first housing portion and the second housing portion are covered with each other to form a receiving space for placing the heating module 100, that is, the housing 210 plays a role in protecting and receiving the heating module 100. Wherein, a fixing structure may be disposed in the first housing portion, and the fixing structure is used for fixing a part of the structure of the heating module 100. Specifically, the securing structure includes, but is not limited to, a securing slot, a clip (e.g., a resilient clip), and the like. The outer surface of the second housing part is provided with a mounting groove for mounting the functional panel 230.

The function panel 230 may be a touch screen that may be provided with one or more virtual controls. The function panel 230 may also include one or more physical buttons, where the virtual control or the physical buttons generate corresponding control signals to control the heating module 100 to operate under the triggering of the control operation of the user.

In this embodiment, the heating module 100 is configured to generate an alternating magnetic field with a direction that continuously changes under the excitation of an alternating current, so that a vortex current is generated in a metal conductor (for example, a pot placed on the electrical apparatus 200) in the alternating magnetic field, and then the metal conductor is heated under the action of the vortex current. Specifically, the number of the heating modules 100 may be plural, and the plurality of heating modules 100 are disposed inside the housing 210 according to a certain arrangement manner, so that when the cooker is placed in the electrical apparatus 200, at least one heating module 100 is corresponding to the cooker for heating the cooker. Therefore, the pot can be more flexible when placed on the electric device 200. Specifically, the number of the heating modules 100 may be greater than or equal to 30, for example, the number of the heating modules 100 is 40, 60, 80, etc. In the embodiment shown in fig. 1, the number of the heating modules 100 is 50, 50 heating modules 100 are arranged in 10 columns, and 10 columns of heating modules 100 are sequentially arranged at intervals in the length direction of the electrical apparatus 200. The virtual coil 250 is a possible placement position of the pot, and when the pot is placed on the placement position, there is a heating module No. 1, a heating module No. 2, a heating module No. 6, a heating module No. 7, a heating module No. 8, a heating module No. 12, a heating module No. 13, a heating module No. 14, a heating module No. 17, and a heating module No. 18 for heating the pot.

Referring to fig. 2 to 4, the heating module 100 may include a coil 10 and a magnet ring 30, the coil 10 being configured to perform a heating function under current excitation. The magnet ring 30 is disposed at one side of the coil 10, and is provided with a first through hole 300, and the first through hole 300 penetrates opposite sides of the magnet ring 30. The magnet ring 30 may include a plurality of magnet portions 320, the plurality of magnet portions 320 being sequentially arranged to circumferentially define the first through-hole 300. Among the plurality of magnet portions 320, there are at least two magnet portions 320 disposed at intervals in the circumferential direction of the first through hole 300 such that a gap 340 is formed between the two spaced magnet portions 320, the gap 340 communicating with the first through hole 300. Of the plurality of magnet portions 320, there are at least two adjacent end portions 3200 of the adjacent magnet portions 320 that are fitted to each other.

Therefore, the magnet ring 30 in the present embodiment is formed by a plurality of magnet portions 320 in common (for example, the plurality of magnet portions 320 may be sequentially joined and fitted). In one aspect, the present embodiment can simplify the manufacturing process of the magnet ring 30 and reduce the manufacturing cost of the magnet ring 30. For example, in the case of manufacturing the magnet ring into a single structure, it is necessary to press the magnet ring into a shape by a large-tonnage machine, but in the present application, when manufacturing the magnet ring 30, a plurality of magnet portions 320 can be pressed by a small-tonnage machine, and then the plurality of magnet portions 320 are spliced into the magnet ring 30, so that the manufacturing cost is reduced. On the other hand, since the magnet ring 30 is formed by splicing the plurality of magnet portions 320, the occurrence probability of the breakage event of the magnet ring 30 during transportation and assembly can be reduced, and the service life of the magnet ring 30 can be improved.

Further, after the plurality of magnet portions 320 are spliced into the magnet ring 30, there may be a gap 340 communicating with the first through hole 300, that is, the magnet ring 30 is not a complete ring structure. The existence of the gap 340 makes the magnet ring 30 in an alternating magnetic field, and the magnetic force lines inside the magnet ring 30 cannot form a closed loop, so as to prevent heat generated inside the magnet ring 30 and ensure normal use of the magnet ring 30.

Here, the electrical apparatus 200 in the present embodiment adopts a mode of heating by a plurality of heating modules 100, so that the volume of a single heating module 100 is small. After the plurality of magnet portions 320 are spliced into the magnet ring 30, a gap 340 may be formed between two adjacent magnet portions 320, and the number of gaps 340 may be one or more. In order to ensure that the single heating module 100 has better working efficiency, at least two magnet portions 320 of the plurality of magnet portions 320 are spliced to reduce the number of gaps 340 as much as possible, so that the spliced magnet ring 30 can approach the magnetism collecting effect of the whole magnet ring, and further the working efficiency of the single heating module 100 is ensured.

The components of the heating module 100 are described in detail below.

In this embodiment, the coil 10 is generally annular (e.g., circular, polygonal, etc.) for heating under current excitation. For example, two ends of the coil 10 may be connected in an inverter circuit (e.g., a single-phase half-bridge inverter circuit, a single-phase full-bridge inverter circuit, etc.), so that an alternating current is generated in the coil 10 under the control of the inverter circuit, thereby forming an alternating magnetic field for heating the metal conductor. Specifically, the coil 10 may be wound from an enamel wire along a designated center.

In the present embodiment, the magnet ring 30 is substantially annular (e.g., annular, polygonal, etc.), and is disposed at one side of the coil 10, and can be used to gather magnetic lines of force, so as to improve the working efficiency of the heating module 100. When the heating module 100 is disposed in the electrical apparatus 200, the electrical apparatus 200 may be provided with a carrying surface for carrying a pot, and the magnet ring 30 is disposed on a side of the coil 10 away from the carrying surface. In particular, the magnet ring 30 may be made of ferrite magnetic material.

In the present embodiment, the magnet ring 30 may include a plurality of magnet portions 320, and the plurality of magnet portions 320 are sequentially arranged to surround the first through hole 300. Among the plurality of magnet portions 320, there are at least two magnet portions 320 disposed at intervals in the circumferential direction of the first through hole 300 such that a gap 340 is formed between the two spaced magnet portions 320, the gap 340 communicating with the first through hole 300. Of the plurality of magnet portions 320, there are at least two adjacent end portions 3200 of the adjacent magnet portions 320 that are fitted to each other.

In some possible embodiments, the number of the gaps 340 may be one, that is, only two ends of the magnet portions 320 are spaced apart from each other in the plurality of magnet portions 320, and the plurality of magnet portions 320 may form a ring structure that is continuous with each other, so that the spliced magnet ring 30 may approach the magnetism collecting effect of the whole magnet ring, and further the working efficiency of the heating module 100 is ensured.

In other possible embodiments, the number of gaps 340 may be plural, and the number of gaps 340 is smaller than the number of magnet portions 320, that is, there are ends of at least two magnet portions 320 that are fitted to each other among the plurality of magnet portions 320. For example, in the case where the number of the magnet portions 320 is three, one end portion of two of the magnet portions 320 is fitted to each other, and the end portion of the remaining one of the magnet portions 320 is spaced apart from the end portions of the other two of the magnet portions 320, respectively, to form two gaps 340, respectively.

Specifically, the number of the magnet portions 320 may be 2, 3, 4, etc., and the number of the magnet portions 320 and the splicing manner of the plurality of magnet portions 320 are not particularly limited in this embodiment.

In some possible embodiments, as shown in fig. 4, the surrounding structure formed by the plurality of magnet portions 320 surrounding the first through hole 300 is circular, that is, the outer contour of the magnet ring 30 is substantially circular. In this case, the coil 10 may be wound into a circular shape, and the projection area of the coil 10 in the axial direction of the first through hole 300 is substantially the same as the projection area of the magnet ring 30 in the axial direction of the first through hole 300, so that the magnet ring 30 can sufficiently gather magnetic lines of force on one side of the coil 10, thereby ensuring the working efficiency of the heating module 100. In addition, the outer contours of the coil 10 and the magnet ring 30 are circular, so that the stress of the coil 10 and the magnet ring 30 is more uniform, and the mechanical strength is higher.

In other possible embodiments, referring to fig. 5, the surrounding structure formed by the plurality of magnet portions 320 surrounding the first through hole 300 is polygonal, for example, pentagonal, hexagonal, etc., that is, the outer contour of the magnet ring 30 is substantially polygonal. Therefore, the outer contour of the heating module 100 provided with the magnet ring 30 may be also provided in a polygonal shape, and when a plurality of heating modules 100 are arranged inside the electric device 200, adjacent sides of adjacent heating modules 100 may be attached to each other. Compared with the circular heating module 100, the polygonal heating module 100 can reduce gaps when being arranged, so that the plurality of heating modules 100 are more compact when being arranged, and further the heating efficiency of the cooker is improved. Specifically, the surrounding structure formed by the plurality of magnet portions 320 surrounding the first through hole 300 may be a regular polygon, for example, a regular pentagon, a regular hexagon, or the like.

In some possible embodiments, the fitting structure between the end portions 3200 of the two magnet portions 320 fitted to each other is laminated to each other in the axial direction of the first through hole 300. The above-mentioned "fitting structures are stacked on top of each other" is understood to mean that the two end portions 3200 are provided with structures nested with each other, for example, by means of grooves, recesses and the like, and structures cooperating with protrusions and protrusions. For example, one of the ends 3200 may be embedded within the other end 3200. In the present embodiment, at least a part of the structure of one end portion 3200 and at least a part of the structure of the other end portion 3200 overlap in the axial direction of the first through hole 300, so that the surfaces of the two end portions 3200 can be bonded to each other, thereby ensuring the connection reliability between the two magnet portions 320. Referring to fig. 6 and 7, fig. 6 and 7 show two possible embodiments of the "fitting structure", respectively.

The specific structure of the magnet portion 320 will be described below taking the number of the magnet portions 320 as two as an example.

Referring to fig. 8, the plurality of magnet portions 320 may include a first magnet portion 3210 and a second magnet portion 3230, and the first magnet portion 3210 and the second magnet portion 3230 may have a semicircular shape, respectively. The first magnet portions 3210 and the second magnet portions 3230 are disposed at intervals in the circumferential direction of the first through hole 300, and a gap 340 is disposed between the first magnet portions 3210 and the second magnet portions 3230, and the gap 340 extends in the radial direction of the first through hole 300.

In this embodiment, the first magnet portion 3210 may include a first end portion 3212 and a second end portion 3214, and the first end portion 3212 and the second end portion 3214 are located at both ends of the first magnet portion 3210, respectively. The second magnet portion 3230 includes a third end portion 3232 and a fourth end portion 3234, the third end portion 3232 and the fourth end portion 3234 being located at both ends of the second magnet portion 3230, respectively. Wherein the gap 340 is located between the first and third ends 3212, 3232, i.e., the first and third ends 3212, 3232 are oppositely spaced apart to define the gap 340.

The second end portion 3214 and the fourth end portion 3234 are fitted. Specifically, the first magnet portion 3210 may include a body portion 3216 and a protrusion portion 3218, and the body portion 3216 and the protrusion portion 3218 may be an integrally formed structure. The protruding portion 3218 is located at the second end portion 3214 and protrudes with respect to the body portion 3216, and a height difference exists between the protruding portion 3218 and the body portion 3216 on the annulus of the magnet ring 30, such that the second end portion 3214 is substantially in a "step-like" configuration. Specifically, the protrusion 3218 is substantially recessed relative to the body 321, which recess may be used to accommodate a portion of the structure of the fourth end 3234. The fourth end portion 3234 is provided with a receiving groove 3236, and the protruding portion 3218 is fitted into the receiving groove 3236 so that the surfaces of the second end portion 3214 and the fourth end portion 3234 are fitted to each other, ensuring connection reliability between the first magnet portion 3210 and the second magnet portion 3230.

It will be appreciated that there is also a recess 3219 in the second end portion 3214 and a protrusion 3236 on the fourth end portion 3234 that mates with the recess 3219, the protrusion 3236 also engaging the recess 3219 when the protrusion 3218 is received in the receiving recess 3236, such that the second and fourth end portions 3214, 3234 are of complementary but identical configuration. Therefore, the first magnet portion 3210 and the second magnet portion 3230 shown in fig. 8 have substantially the same or symmetrical shape, which simplifies the manufacturing difficulty of the magnet portion 320 and reduces the manufacturing cost of the magnet portion 320. Specifically, when two magnet portions 320 with substantially the same or symmetrical shape are spliced into the magnet ring 30, only one of the magnet portions 320 needs to be turned over, and then the two end portions 3200 provided with the protrusions are spliced, so that the splicing process of the magnet ring 30 is simpler and more convenient.

In this embodiment, the heating module 100 may further include a first bracket 50 and a second bracket 70, and the first bracket 50 and the second bracket 70 serve to fix and protect the coil 10 and the magnet ring 30. Wherein the first bracket 50 and the second bracket 70 are respectively located at opposite sides of the magnet ring 30 such that the first bracket 50, the magnet ring 30 and the second bracket 70 are sequentially stacked in an axial direction of the first through hole 300, and the first bracket 50 and the second bracket 70 are connected to each other to fix the magnet ring 30.

Referring to fig. 9 and 10, the first bracket 50 is generally in the shape of a cover, and is disposed on a side of the magnet ring 30 facing away from the second bracket 70, so as to protect the magnet ring 30. Specifically, the first bracket 50 may include a first cover 520, where the first cover 520 is substantially annular (e.g., circular, polygonal, etc.), and is disposed on a side of the magnet ring 30 facing away from the second bracket 70. Specifically, the shape of the first cover 520 may be substantially the same as the shape of the magnet ring 30, and the projection of the first cover 520 in the axial direction of the first through hole 300 may substantially cover the magnet ring 30.

In this embodiment, the coil 10 may be disposed on the first bracket 50, and the first bracket 50 plays a role of fixing the coil 10. In some possible embodiments, the first covering portion 520 may be provided with a fixing groove 500, the fixing groove 500 being circumferentially disposed along the first covering portion 520, and the coil 10 being wound in the fixing groove 500. Specifically, the fixing groove 500 may be disposed at a sidewall of the first covering portion 520, and a groove depth of the fixing groove 500 may be greater than or equal to a radial length of the coil 10, so that the coil 10 may be completely wound in the fixing groove 500, thereby providing sufficient protection for the coil 10. In other possible embodiments, a receiving cavity may be disposed on one side of the first cover portion 520, and the wound coil 10 may be embedded in the receiving cavity, and the specific arrangement manner of the coil 10 is not limited in this embodiment.

The second bracket 70 is substantially in the shape of a cover, and is disposed on a side of the magnet ring 30 facing away from the first bracket 50, and can serve as a support for the magnet ring 30. Specifically, the second bracket 70 may include a second cover portion 720 and a support portion 740, wherein the second cover portion 720 is substantially annular (e.g., circular, polygonal, etc.) disposed on a side of the magnet ring 30 facing away from the first bracket 50. Specifically, the shape of the second cover 720 may be substantially the same as the shape of the magnet ring 30, and the projection of the second cover 720 in the axial direction of the first through hole 300 may substantially cover the magnet ring 30. Therefore, the present embodiment fixes the magnet ring 30 by the first and second cover parts 520 and 720 being fastened to each other.

The support portion 740 is disposed on a side of the second cover portion 720 facing away from the magnet ring 30, and serves to support the second cover portion 720, the magnet ring 30, the first bracket 50, and the coil 10. The supporting portion 740 and the second covering portion 720 may be integrally formed, so that the overall structure of the second bracket 70 is more firm and reliable. The number of the supporting portions 740 may be plural, and the plurality of supporting portions 740 are disposed at intervals along the circumferential direction of the second covering portion 720. Specifically, the support 740 may be a support column. When the heating module 100 is installed inside the electrical equipment 100, the air gap exists between the second cover portion 720 and the bottom wall of the electrical equipment 100 due to the existence of the support column, so that the heat dissipation efficiency of the heating module 100 is improved, and the service life of the heating module 100 is ensured.

In some possible embodiments, the first bracket 50 may further include a first connection part 540, and the first connection part 540 is connected to a side of the first cover part 520 facing the magnet ring 30. The first connection part 540 and the first bracket 50 may be integrally formed, so that the overall structure of the first bracket 50 is more firm and reliable. Specifically, the first connection portion 540 may be a snap structure for snap-fit connection with the second bracket 70. Specifically, the second bracket 70 may be provided with a second through hole 700, and the second through hole 700 is coaxial with and communicates with the first through hole 300.
