Description

Technical Field

[0001] This invention relates to the field of cooking appliance technology, specifically to a coil assembly and an electromagnetic cooking appliance. Background Technology

[0002] In home appliances, electromagnetic heating is almost universally used. Especially in multi-burner stoves and induction cookers that use electromagnetic heating, the heating elements are almost always fixed in one or a few areas. The remaining areas of the heating panel lack heating coils, allowing only localized heating. Furthermore, the coils must be precisely aligned with the desired heating point; misalignment will affect cooking results. Therefore, multiple heating points are needed for overall heating. However, traditional electromagnetic heating coils require complex assembly of the magnet and coil windings, making them unsuitable for induction cookers that require overall heating.

[0006] The coil winding is mounted on one of the mounting sides; and,

[0007] A magnet is disposed on another of the mounting sides, the magnet being used to mount an electromagnetic cooking appliance.

[0008] The present invention also proposes an electromagnetic cooking appliance, including...

[0009] A housing, the housing including a mounting base and a panel covering the mounting base, the mounting base having multiple mounting positions; and,

[0010] Multiple coil assemblies are installed at multiple mounting stations. Each coil assembly includes a mounting bracket, a coil winding, and a magnet. The mounting bracket includes two mounting sides arranged opposite each other. The coil winding is mounted on one mounting side, and the magnet is located on the other mounting side. The magnet is used to mount the electromagnetic cooking appliance.

[0011] In each of the installation stations, the coil winding, the mounting bracket, and the magnet are stacked sequentially along the direction from the panel to the mounting base.

[0016] Optionally, the mounting base is provided with a snap groove, which forms a corresponding snap-fit ​​portion.

[0017] Optionally, the buckle groove is configured as an elongated groove;

[0018] Correspondingly, the fastener is elongated.

[0019] Optionally, the mounting base has a first rib on the side near the magnet and around the periphery of the groove to form the protrusion.

[0020] Optionally, the mounting bracket is provided with a second through hole, and the fastener is hollow;

[0021] The second through hole communicates with the cavity of the fastener to form a wire passage.

[0022] Optionally, the mounting bracket has a second rib on the mounting side where the coil winding is mounted and around the second through hole. The second rib is semi-enclosed to form a wire groove that connects to the second through hole.

[0023] Optionally, the mounting base includes:

[0024] The base; and,

[0025] Multiple mounting strips are spaced apart within the base, and each mounting strip has multiple buckle slots.

[0026] Optionally, each of the mounting strips is movable along the direction from the base to the panel and is fitted with at least one elastic abutment between itself and the base.

[0027] Optionally, each of the mounting strips has at least one sliding portion on the side near the base;

[0028] The base has at least one groove corresponding to the sliding part, and the sliding part is movably disposed in the corresponding groove to guide the movement of the corresponding mounting strip.

[0029] Optionally, the mounting base is provided with a groove to form the mounting station;

[0030] Correspondingly, the groove is used for the magnet to be held and embedded.

[0031] Optionally, the mounting base includes:

Each installation position can install one coil assembly, and each coil assembly forms a heating unit in the electromagnetic cooking appliance. The coil winding is installed on one installation side of the mounting bracket, so that when the mounting bracket is installed in the corresponding installation position, it is positioned close to the panel of the electromagnetic cooking appliance to heat the cookware on the panel. Since the magnet is located on the other installation side of the mounting bracket, when the mounting bracket is installed in the corresponding installation position... When in position, the magnet is independently installed at the installation station, thereby achieving a magnetic focusing effect on the corresponding coil winding to improve the heating efficiency of the cookware. Compared with the prior art, which requires a separate fixed bracket between the coil winding and the magnet to separate them when the coil winding and the magnet are combined and installed in the electromagnetic heating coil, the present invention makes the magnet and the mounting bracket independent of each other. The magnet can be directly installed at the corresponding installation station, and the specific installation form and installation position are diverse. The magnet installation method is simple, and the magnet does not need to be installed on the mounting bracket. The coil assembly structure is simple. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0048] In home appliances, electromagnetic heating is almost universally used. Especially in multi-burner stoves and induction cookers that use electromagnetic heating, the heating elements are almost always fixed in one or a few areas. The remaining areas of the heating panel lack heating coils, allowing only localized heating. Furthermore, the coils must be precisely aligned with the desired heating point; misalignment will affect cooking results. Therefore, multiple heating points are needed for overall heating. However, traditional electromagnetic heating coils require complex assembly of the magnet and coil windings, making them unsuitable for induction cookers that require overall heating.

[0049] In view of this, the present invention proposes a coil assembly, Figures 1 to 6 This is one embodiment of the present invention.

[0050] Please see Figures 1 to 3 The coil assembly 3 includes a mounting bracket 302, a coil winding 301, and a magnet 2. The mounting bracket 302 includes two mounting sides arranged opposite to each other. The coil winding 301 is mounted on one of the mounting sides. The magnet 2 is located on the other mounting side and is used to be mounted on the electromagnetic cooking appliance 100.

[0051] In the technical solution of the present invention, the coil assembly 3 is used to be installed in the electromagnetic cooking appliance 100, and the electromagnetic cooking appliance 100 has multiple installation positions, each installation position can be equipped with one coil assembly 3, and each coil assembly 3 forms a heating unit in the electromagnetic cooking appliance 100; wherein, the coil winding 301 is installed on one of the installation sides of the mounting bracket 302, so that when the mounting bracket 302 is installed in the corresponding installation position, it is close to the panel 102 of the electromagnetic cooking appliance 100 to heat the pot on the panel 102, and since the magnet 2 is provided on the other installation side of the mounting bracket 302, the magnet 2 is located on the other installation side of the mounting bracket. When 302 is installed at the corresponding installation position, the magnet 2 is independently installed at the installation position, thereby achieving a magnetizing effect on the corresponding coil winding 301 to improve the heating efficiency of the cookware. Compared with the prior art, which requires a separate fixed bracket to separate the coil winding and the magnet in the electromagnetic heating coil plate, the present invention makes the magnet 2 and the installation bracket 302 independent of each other. The magnet 2 can be directly installed at the corresponding installation position, and the specific installation form and installation position are diversified. The installation method of the magnet 2 is simple, and the installation bracket 302 does not need to install the magnet 2. The assembly structure of the coil assembly 3 is simple.

[0052] Furthermore, since the electromagnetic cooking appliance 100 to which the coil assembly 3 is applied has multiple installation positions, and the coil assembly 3 is installed on each installation position, that is, multiple coil assemblies 3 are densely distributed on the inner side of the panel 102 so that the entire area of ​​the panel 102 can be used to place the pot for heating; however, the larger the size of the coil assembly 3, the larger the heating blind zone between two adjacent coil assemblies 3, which will affect the heating effect of the electromagnetic cooking appliance 100 on the pot. Preferably, the outer diameter of the coil assembly 3 is less than or equal to 80mm.

[0053] Please refer to it again. Figures 1 to 3 The present invention also proposes an electromagnetic cooking appliance 100, which includes a housing 1 and a plurality of coil assemblies 3. The housing 1 includes a mounting base 101 and a panel 102 covering the mounting base 101. The mounting base 101 is provided with a plurality of mounting positions. The plurality of coil assemblies 3 are installed corresponding to the plurality of mounting positions. In each mounting position, the coil winding 301, the mounting bracket 302, and the magnet 2 are sequentially stacked along the direction from the panel 102 to the mounting base 101. The specific structure of the coil assembly 3 is as described in the above embodiments. Since the electromagnetic cooking appliance 100 adopts all the technical solutions of all the above embodiments, it also has the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0054] That is, by providing multiple mounting positions on the mounting base 101, and installing the coil assembly 3 at each corresponding mounting position, a heating unit is formed in the electromagnetic cooking appliance 100. The coil assembly 3 includes the mounting bracket 302 and the coil winding 301. The coil winding 301 is mounted on the mounting bracket 302, so that when the mounting bracket 302 is installed at the corresponding mounting position, it is positioned close to the panel 102 to heat the cookware located on the panel 102. At each mounting position, the magnet 2 is independently installed and disposed on the coil winding 3. 01 is located near the mounting base 101, thereby achieving a magnetic focusing effect on the corresponding coil winding 301 to improve the heating efficiency of the cookware. Compared with the prior art, which requires a separate fixed bracket between the coil winding and the magnet to separate the magnet and the coil winding when the coil winding and the magnet are combined and installed in the electromagnetic heating coil, the present invention makes the magnet 2 and the mounting bracket 302 independent of each other. The magnet 2 can be directly installed on the corresponding installation position, and the specific installation form and installation position are diversified. The installation method of the magnet 2 is simple. The mounting bracket 302 does not need to install the magnet 2. The assembly structure of the coil assembly 3 is simple.

[0055] The specific type of the electromagnetic cooking appliance 100 is not limited. In this embodiment, the electromagnetic cooking appliance 100 can be an induction cooker. In addition, when each mounting bracket 302 is installed at the corresponding mounting position, the coil winding 301, the mounting bracket 302 and the magnet 2 are stacked in sequence. That is, the mounting bracket 302 is located between the magnet 2 and the coil winding 301, which can separate the magnet 2 and the coil winding 301 to avoid the installation distance between the magnet 2 and the coil winding 301 being too close, which would cause the coil winding 301 to be affected by the magnet 2 and cause discharge breakdown when alternating current is applied.

[0056] Furthermore, since the magnet 2 is independently installed at the installation station, to prevent its position from shifting during use of the electromagnetic cooking appliance 100 after installation at the installation station, thus affecting the magnetic focusing effect of the corresponding coil winding 301, specifically, at each installation station, the magnet 2 is fixedly held in place. By setting the magnet 2 to be fixedly held in place at the corresponding installation station, compared to the conventional method of fixing the magnet 2 with adhesive in the prior art, the magnet 2 is rigidly held in place at the installation station, thereby limiting the relative displacement between the magnet 2 and the coil winding 301 in multiple directions; in addition, the magnet 2 can also be glued to the contact surface when held in place at the installation station to achieve a better fixing effect.

[0057] In one embodiment, the mounting base 101 is provided with a protrusion 4 to form the mounting station; the magnet 2 is provided with a first through hole 5 for the protrusion 4 to pass through and hold. By providing the protrusion 4 at each mounting station, when the protrusion 4 is embedded in the corresponding first through hole 5, its outer peripheral portion abuts against the hole wall of the first through hole 5, thereby achieving the limiting and fixing of the magnet 2.

[0058] In another embodiment, the mounting base 101 is provided with a groove 13 to form the mounting station; correspondingly, the groove 13 is used for the magnet 2 to be held and embedded. By providing a groove 13 in each mounting station, the groove 13 is used for the corresponding magnet 2 to be embedded, and its groove wall part abuts against the outer periphery of the magnet 2, thereby restricting the periphery of the magnet 2 to achieve the effect of limiting and defining the position of the magnet 2.

[0059] It should be noted that, in the two embodiments described above, regardless of whether the protrusion 4 or the groove 13 is provided on the installation station to limit and fix the magnet 2, the arrangement form and number of the magnet 2 are not limited. For example, if the magnet 2 and the coil assembly 3 are installed on one installation station, at least part of the projection of the coil winding 301 of the coil assembly 3 along the direction from the panel 102 to the mounting base 101 can fall on the corresponding magnet 2 installed on the same installation station. The magnet 2 can have a magnetic focusing effect on the corresponding coil winding 301, making the magnetic field lines of the coil winding 301 more concentrated, further improving the heating efficiency, and reducing the electromagnetic field radiated to the mounting base 101.

[0060] Please see Figure 3 and Figure 4 In the above embodiment, based on the first through hole 5 on the magnet 2, the mounting bracket 302 is further provided with a fastener 6 on the side close to the magnet 2, and the mounting base 101 is provided with a fastening part 7. The fastener 6 passes through the first through hole 5 of the magnet 2 and is fastened to the fastening part 7. The coil assembly 3 is fixedly installed by fastening the fastener 6 onto the mounting base 101. Since the magnet 2 is sandwiched between the mounting bracket 302 and the mounting base 101, the fastener 6 is designed to pass through the magnet 2 and fasten onto the mounting base 101 when the mounting bracket 302 is installed at the mounting position. Therefore, the fastener 6 is designed to pass directly through the first through hole 5 on the magnet 2. The first through hole 5 serves to allow the corresponding protrusion 4 to be embedded and also allows the fastener 6 to pass through, thereby improving its functional versatility and the overall compactness of the installation. The form of the fastening part 7 provided at the mounting position is not limited. It can be a slot corresponding to the position of the fastener 6 for the fastener 6 to pass through and fasten, or it can be a fastening part in which the holding end of the fastener 6 fastens onto the fastening part 7 when the fastener 6 fastens onto the fastening part 7.

[0061] The number of fasteners 6 is not limited; there can be one or more. If there is only one fastener 6, it can be installed in the middle of the mounting bracket 302, thereby improving its stability when installing the mounting bracket 302. If there are multiple fasteners 6, they can be arranged around the mounting bracket 302, thereby improving its stability when installing the mounting bracket 302. Preferably, in this embodiment, there is only one fastener 6 located in the middle of the mounting bracket 302. Compared with the solution of having multiple fasteners 6, there is only one attachment point between the mounting bracket 302 and the mounting base 101. Under the premise of ensuring that the mounting bracket 302 and the mounting base 101 are firmly fixed, it is more convenient to disassemble.

[0062] Preferably, in this embodiment, the mounting base 101 is provided with a snap-fit ​​groove 7a, which forms the corresponding snap-fit ​​part 7. Therefore, when installing the coil assembly 3 at the installation station, the fastener 6 on the mounting bracket 302 can be directly snapped into the corresponding snap-fit ​​groove 7a. That is, the coil assembly 3 and the mounting strip 10b are installed using a rigid snap-fit ​​method, improving the reliability of the connection between the two.

[0063] Furthermore, the buckle groove 7a is configured as an elongated groove; correspondingly, the fastener 6 is also elongated. By configuring both the buckle groove 7a and the fastener 6 as elongated shapes, when the coil assembly 3 is installed on the installation station, the fastener 6 and the buckle groove 7a are in a non-rotational fit, thereby preventing the coil assembly 3 from rotating when installed on the installation station and improving the stability of its connection.

[0064] Furthermore, since the first through hole 5 of the magnet 2 needs to be held by the protrusion 4 and also allows the fastener 6 to pass through, in order to ensure that the fastener 6 can pass through without being affected when the protrusion 4 is held in the first through hole 5, specifically, the mounting base 101 has a first rib 4a around the periphery of the fastening groove 7a on the side close to the magnet 2, thus forming the protrusion 4. By providing the first rib 4a around the periphery of the fastening groove 7a, and the first rib 4a protruding from the fastening groove 7a along the direction from the mounting base 101 to the panel 102, it can be embedded into the first through hole 5 of the magnet 2 when the magnet 2 is mounted on the mounting base 101; and the surrounding first rib 4a will not block the opening positions at both ends of the fastening groove 7a, so that the fastener 6 can be smoothly embedded into the fastening groove 7a.

[0065] Furthermore, since the coil winding 301 is formed by winding multiple turns of coil sequentially from the inside out, it has an inner lead on its inner side and an outer lead on its outer side. When the coil winding 301 is mounted on the mounting bracket 302, it is difficult for the inner lead on its inner side to be routed out of the mounting bracket 302 and connected to the circuit integrated motherboard 16. Therefore, a second through hole 8 is provided on the mounting bracket 302, and the fastener 6 is hollow. The second through hole 8 communicates with the cavity of the fastener 6 to form a wire passage. The second through hole 8 through the mounting bracket 302 corresponds to the inner side of the coil winding 301. That is, the inner lead of the coil winding 301 can be introduced into the wire passage from one end opening of the second through hole 8, and then pass through the wire passage from the cavity of the fastener 6 to the outer side of the mounting bracket 302, thereby facilitating the wiring and installation of the coil winding 301.

[0066] Furthermore, the mounting bracket 302 has a second rib 9 on the mounting side of the coil winding 301 and around the second through hole 8. The second rib 9 is semi-enclosed to form a wire passage groove 10 communicating with the second through hole 8. Since the second through hole 8 is located inside the coil winding 301, the second rib 9 is also located inside the coil winding 301. The second rib 9 is semi-enclosed to form the wire passage groove 10, and the inner lead of the coil winding 301 can be guided from the wire passage groove 10 into the wire passage channel. The wire passage groove 10 limits the movement of the inner lead of the coil winding 301.

[0067] Furthermore, the mounting bracket 302 has a mounting groove recessed on one of the mounting sides where the coil winding 301 is mounted, and the coil winding 301 is correspondingly mounted in the mounting groove, thereby protecting the coil winding 301.

[0068] In addition, the coil assembly 3 also includes a heat insulation plate 303, wherein the heat insulation plate 303 is installed on the side of the coil winding 301 away from the mounting bracket 302, so as to prevent the heat on the panel 102 from spreading to the coil winding 301 when the pot is placed on the panel 102 for heating; wherein the heat insulation plate 303 and the coil winding 301 can be bonded together to each other as one piece when not installed on the mounting bracket 302, so as to facilitate assembly onto the mounting bracket 302, and the arrangement of the heat insulation plate 303 is not limited. In this embodiment, the heat insulation plate 303 is a mica sheet.

[0069] Furthermore, the coil assembly 3 also includes a temperature measuring element 304. The temperature measuring element 304 can be mounted on the heat insulation plate 303 or on the mounting bracket 302. The temperature measuring element 304 protrudes from the coil winding 301. When the corresponding coil assembly 3 is installed in the electromagnetic cooking appliance 100, and the temperature measuring element 304 is close to the inner side of the panel 102, the temperature measuring element 304 can measure the temperature of the area where the panel 102 overlaps with the corresponding coil assembly 3, thereby monitoring the temperature of the panel 102 and the cookware during cooking. Temperature is monitored in real time. Specifically, in this embodiment, the temperature measuring element 304 is installed on the mounting bracket 302 and near its center. Correspondingly, a third through hole 14 can be opened in the center of the heat insulation plate 303. The third through hole 14 connects to the wire passage. When the temperature measuring element 304 is installed on the mounting bracket 302, its lead wire can extend from the third through hole 14 into the wire passage and extend out of the outside of the mounting bracket 302, thereby facilitating the wiring connection of the lead wire of the temperature measuring element 304.

[0070] Please see Figure 1 The mounting base 101 includes a base 10a and multiple mounting strips 10b, which are spaced apart within the base 10a. Each mounting strip 10b has multiple slots 7a. By arranging multiple mounting strips 10b spaced apart within the base 10a and having multiple slots 7a on each mounting strip 10b, each mounting strip 10b has multiple mounting positions for mounting the magnet 2 and the coil assembly 3. Each coil assembly 3 can be independently detached from the mounting strip 10b, and each mounting strip 10b can also be independently detached from the base 10a, thereby facilitating the installation, removal, and maintenance of the components in the electromagnetic cooking appliance 100.

[0071] The base 10a forms the outer shell frame of the electromagnetic cooking appliance 100. The base 10a is semi-enclosed to form a mounting cavity with one open end. The base 10a includes a mounting base plate 101a and an outer shell base 102a. The outer shell base 102a mainly serves to enclose the mounting cavity and protect the components of the electromagnetic cooking appliance 100. The mounting base plate 101a is located at the bottom of the outer shell base 102a and is mainly used for mounting the internal parts of the electromagnetic cooking appliance 100. In this embodiment, the mounting base plate 101a is used to mount multiple mounting strips 10b. The electromagnetic cooking appliance 100 also includes a cooling fan 15 and a circuit integrated mainboard. 16 and display control board 17, the cooling fan 15, the circuit integrated motherboard 16 and the display control board 17 are all mounted on the mounting base 101a and located in the mounting space formed by the multiple mounting strips 10b and the mounting base 101a. Compared with the multiple coil assemblies 3 and the corresponding magnets 2 being directly mounted on the mounting base 101a, when the multiple mounting strips 10b are installed in the mounting seat 101, they are spaced apart from the mounting seat 101 along the direction from the mounting seat 101 to the panel 102. The mounting space formed by the multiple mounting strips 10b and the mounting base 101a is larger, which makes it easier to assemble the cooling fan 15 and other components in the base 10a.

[0072] Since most induction cooker frames are rectangular, they form a rectangular mounting cavity with an open top. The mounting strips 10b are elongated, so that the two ends of the mounting strips 10b are closer to the two opposite side walls of the base 10a. Multiple mounting strips 10b are spaced apart to make full use of the mounting cavity area of ​​the base 10a.

[0073] The magnet 2 is engaged with the mounting strip 10b via a protrusion 4. The protrusion 4 can be located on the side of the mounting strip 10b near the panel 102 or near the mounting base plate 101a. To ensure the secure installation of the magnet 2, the magnet 2 is installed on the side of the mounting strip 10b near the panel 102, so as to further restrict the separation of the magnet 2 when the mounting bracket 302 is inserted into the fastener 7a by the fastener 6.

[0074] Furthermore, in order to improve the heating efficiency of the coil winding 301 for the cookware placed on the panel 102, at least one elastic support member 11 is installed between each of the mounting strips 10b, which is movable along the direction from the base 10a to the panel 102 and between the strip and the base 10a. In this embodiment, at least one elastic abutment 11 is provided between each mounting strip 10b and the base 10a. The elastic abutment 11 elastically extends and retracts along the direction from the panel 102 to the base 10a, and can abut against the corresponding mounting strip 10b as it moves closer to the panel 102. This allows multiple coil assemblies 3 located on the mounting strip 10b to simultaneously abut against the inner side of the panel 102, achieving a better cooking heating effect. Compared to the electromagnetic heating coils used in the prior art, which require independent installation of elastic elements to abut against the inner side of the corresponding cooking panel 102, in this embodiment, multiple coil assemblies 3 only need to be fixedly installed on the mounting strip 10b, and the elastic abutment 11 is installed between the mounting strip 10b and the base 10a. This reduces the number of elastic abutment 11 required when installing multiple coil assemblies 3, and the installation operation is simpler. The form of the elastic abutment 11 is not limited; it can be a straight spring, a tower spring, etc.

[0075] Since each mounting strip 10b is elongated, at least two elastic support members 11 are provided, spaced apart along the length of the corresponding mounting strip 10b. By making the mounting strip 10b elongated, two elastic support members 11 are installed at the lower end of the mounting strip 10b and spaced apart along its length to support both ends of the mounting strip 10b, thus providing stable support. Preferably, the two elastic support members 11 are symmetrically arranged along the centerline of their length to balance the forces on both ends of the mounting strip 10b.

[0076] Furthermore, since the installation space formed by the intervals between the multiple mounting strips 10b and the base 10a is needed for installing components such as the cooling fan 15, specifically, in this embodiment, on each mounting strip 10b, two elastic abutment members are respectively located near its two ends in the length direction. By maximizing the distance between the two elastic abutment members 11 on the side of the mounting strip 10b near the base 10a, a larger reserved space is provided between the two elastic abutment members 11, thereby facilitating the arrangement and installation of components such as the cooling fan 15.

[0077] Furthermore, since the mounting strip 10b can be movably arranged along the direction from the base 10a to the panel 102, in order to avoid displacement in other directions during its movement stroke, each mounting strip 10b is provided with at least one sliding part 12 on the side near the base plate; the base 10a is provided with at least one sliding groove corresponding to the sliding part 12, and the sliding part 12 is movably disposed in the corresponding sliding groove to guide the movement of the corresponding mounting strip 10b. By providing the sliding part 12 embedded in the groove, both the sliding part 12 and the groove extend and open along the direction from the base 10a to the panel 102. When the elastic abutment abuts against the mounting strip 10b near the panel 102, the groove restricts the sliding direction of the sliding part 12, so that the sliding part 12 can only move along the direction from the bottom to the opening of the groove, thereby restricting the movement direction of the mounting strip 10b corresponding to the installation of the sliding part 12. The number of sliding parts 12 installed on the side of each mounting strip 10b near the base 10a is not limited. Preferably, in this embodiment, two limiting parts are installed at intervals along the width direction of the mounting strip 10b and are located near the end of the mounting strip 10b. Without affecting the installation of other components between the mounting strip 10b and the base 10a, the relative rotation between the mounting strip 10b and the base 10a can be restricted, thereby improving the stability of its installation.

[0078] Please see Figure 1 , Figure 4 and Figure 5 In another embodiment described above, based on the scheme of embedding the magnet 2 into the groove 13 for limiting installation, the mounting base 101 includes a base 10a and a plurality of mounting strips 10b. The mounting strips 10b are spaced apart within the base 10a, and each mounting strip 10b has a plurality of grooves 13 recessed on the side near the base 10a. That is, in this embodiment, by providing a plurality of mounting strips 10b spaced apart on the base 10a, and by allowing the magnet 2 and the coil assembly 3 to be independently mounted on the mounting strips 10b, the installation, removal, and maintenance of the components in the electromagnetic heating unit are facilitated. Furthermore, since the coil assembly 3 is mounted on the side of the mounting strip 10b near the panel 102, and the magnet 2 is mounted on the side of the mounting strip 10b near the base 10a, the disassembly and installation of the two do not interfere with each other, provided that the magnet 2 provides a magnetic focusing effect on the coil winding 301, thus facilitating disassembly and assembly.

[0079] In this embodiment, the coil assembly 3 has the same structure as the coil assembly 3 in the above-described scheme where the protrusion 4 is provided at the mounting position to engage the magnet 2. The structure of the mounting strip 10b is also the same as that of the mounting strip 10b described in the above embodiments. When the elastic abutment 11 is provided on the mounting strip 10b to abut against the coil assembly 3 near the panel 102, the elastic abutment 11 can be disposed between the mounting bracket 302 and the mounting strip 10b, or between the mounting strip 10b and the base 10a. Preferably, in this embodiment, the elastic abutment 11 is disposed between the mounting bracket 302 and the mounting strip 10b, and correspondingly, the mounting strip 10b can be fixedly mounted on the base 10a.

[0080] It is understood that when the elastic support member 11 is located between the mounting bracket 302 and the mounting strip 10b, one end of it is fixed to the mounting bracket 302 by a buckle provided on the mounting bracket 302, so as to facilitate assembly and installation.

[0081] Furthermore, since the coil winding 301, the mounting bracket 302, and the magnet 2 are sequentially stacked on the mounting base 101, the magnet 2 can also be set as the mounting strip 10b, and the snap-fit ​​groove 7a is opened on the magnet 2 corresponding to each mounting position for the coil assembly 3 to be installed.

[0082] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
