Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking utensils, in particular to a magnetic pot rack and electromagnetic oven assembly. BACKGROUND

[0002] The electromagnetic oven uses the principle of electromagnetic induction eddy current to realize direct heating of the pot, and the heating efficiency is high, so the electromagnetic oven is widely used. Since the existing electromagnetic oven usually uses a flat microcrystalline glass plate as the stove surface, it can accommodate flat-bottomed pots, but it cannot stably support non-flat-bottomed pots (i.e. round-bottomed pots). Therefore, to solve the problem of poor universality of the electromagnetic oven, a circular pot support frame is sold on the market, which can be used with the electromagnetic oven to form an electromagnetic oven assembly, so that flat-bottomed pots and non-flat-bottomed pots can be used on the electromagnetic oven.

[0003] The pot support frame can be fixed on the stove surface of the electromagnetic oven by magnetic attraction force, and the temperature of the non-flat-bottomed pot can be accurately detected by the temperature sensor. Moreover, when the electromagnetic oven is working, the conductive coil (or electromagnetic induction coil) on the pot support frame can collect the electromagnetic waves emitted by the heating coil disc (or electromagnetic output coil disc) in the electromagnetic oven and generate a certain induced current, thereby providing working voltage for the temperature sensor.

[0004] However, when the pot support frame is placed on the stove surface of the electromagnetic oven, it is difficult for the user to accurately position the pot support frame to ensure that the conductive coil is concentrically arranged with the heating coil disc, which will result in low installation accuracy of the pot support frame, and the conductive coil cannot be ensured to be located at the best position of the electromagnetic waves emitted by the heating coil disc, affecting the absorption effect of the conductive coil on the electromagnetic waves, and further causing the temperature measurement function to fail. Therefore, the existing electromagnetic oven assembly needs to be further improved. SUMMARY

In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0036] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] Reference is made below Figures 1 to 8 The magnetic pot rack and the electromagnetic oven assembly provided according to the embodiments of the present application are described.

[0038] As Figures 1 to 8 shown, the magnetic pot rack 100 according to the first aspect of the present application can be used in cooperation with the electromagnetic oven 200, so that the electromagnetic oven 200 can be suitable for flat-bottomed cookware and non-flat-bottomed cookware, so as to increase the versatility of the electromagnetic oven 200, thereby improving the user's satisfaction.

[0039] Moreover, the magnetic pot rack 100 of the present embodiment can also realize accurate positioning of the magnetic pot rack 100 on the induction cooker 200, effectively reduce the installation operation difficulty of the magnetic pot rack 100, and improve the installation accuracy of the magnetic pot rack 100, so that the electromagnetic induction coil on the magnetic pot rack 100 can be concentrically arranged with the heating coil disc 230 of the induction cooker 200, ensure that the electromagnetic induction coil is located at the best position of the electromagnetic wave emitted by the heating coil disc 230, improve the absorption effect of the electromagnetic induction coil on the electromagnetic wave, and thus avoid the failure of the temperature measurement function of the magnetic pot rack 100 due to insufficient power supply of the electromagnetic induction coil.

[0040] The magnetic pot rack 100 has a first direction. In the present embodiment, the first direction is assumed to be the up-down direction. The structure of the magnetic pot rack 100 includes a pot support 110 and a first magnetic component 170.

[0041] The pot support 110 is configured to be detachably arranged on the cooking surface 210 of the induction cooker 200. It can be understood that the pot support 110 can be directly placed on the cooking surface 210 of the induction cooker 200 and can be directly taken away from the cooking surface 210 of the induction cooker 200. The pot support 110 can support a pot. In some examples, the pot support 110 is used to support a non-flat-bottom pot, and after the pot support 110 is taken away from the induction cooker 200, the induction cooker 200 can be used to support a flat-bottom pot. In other examples, the pot support 110 is used to support a flat-bottom pot, and after the pot support 110 is taken away from the induction cooker 200, the induction cooker 200 is used to support a non-flat-bottom pot.

[0042] In the present embodiment, as shown in FIG. 1, Figures 1 to 3 The pot support 110 is in the shape of a circular ring, and the pot support 110 can stably support a non-flat-bottom pot. The shape of the pot support 110 can be designed according to actual needs, which is not specifically limited here. The pot support 110 can be made of a high-temperature-resistant non-magnetic material such as stainless steel, plastic, etc.

[0043] The pot support 110 is provided with a temperature measurement sensor 130 and an electromagnetic induction coil. The temperature measurement sensor 130 and the electromagnetic induction coil are electrically connected to each other through a wire. The temperature measurement sensor 130 is configured to be in contact with a pot and collect temperature data of the pot. The electromagnetic induction coil is configured to cooperate with the induction cooker 200 and generate electric energy. Specifically, the electromagnetic induction coil can collect the leakage electromagnetic wave of the heating coil disc 230 of the induction cooker 200 when the heating coil disc 230 electromagnetically induces and heats the pot, so that the electromagnetic induction coil can generate an induced electromotive force, thereby enabling the electromagnetic induction coil to provide the required voltage for the operation of the temperature measurement sensor 130, and ensuring that the temperature measurement sensor 130 can normally work. The electromagnetic induction coil has a central axis, and the length of the central axis extends along the first direction.

[0044] The first magnetic component 170 is fixedly connected with the pot support 110, and the first magnetic component 170 is provided with a plurality of first magnetic components 170, and the plurality of first magnetic components 170 are arranged in a circumferential uniform manner around the center axis of the electromagnetic induction coil. Specifically, the structure of the first magnetic component 170 comprises a permanent magnet 172 and a magnetic conducting piece 171, and the permanent magnet 172 and the magnetic conducting piece 171 are fixedly connected with each other. The opposite ends of the permanent magnet 172 extending in the first direction are respectively S pole and N pole, and the opposite ends of the magnetic conducting piece 171 extending in the direction perpendicular to the center axis are both provided with the permanent magnet 172, and the magnetic poles of the two permanent magnets 172 are opposite, and the two permanent magnets 172 are located on the side of the magnetic conducting piece 171 away from the temperature sensor 130 in the first direction.

[0045] It can be understood that the number of the first magnetic component 170 is not limited to two. For each first magnetic component 170, the magnetic conducting piece 171 extends in the horizontal direction, one of the permanent magnets 172 on the magnetic conducting piece 171 presents the state of N pole upward and S pole downward, and the other permanent magnet 172 on the magnetic conducting piece 171 presents the state of N pole downward and S pole upward. The temperature sensor 130 is located above the first magnetic component 170 and can be in direct contact with the pot to detect the real-time temperature of the pot. The two permanent magnets 172 are both located below the magnetic conducting piece 171. The magnetic conducting piece 171 is made of a magnetic conducting material such as ferrite. The permanent magnet 172 can be a permanent magnet or a permanent steel.

[0046] Since the first magnetic component 170 adopts the above structure design, the magnetic fields of the two permanent magnets 172 can act on the magnetic conducting piece 171, so that the magnetic conducting piece 171 can effectively conduct the magnetic field, so that the magnetic flux can be transmitted along the magnetic conducting piece 171, thereby causing one magnetic conducting piece 171 to form a magnetic force circle together with the two permanent magnets 172, and enhancing the magnetic field strength and effect of the first magnetic component 170. Moreover, the two permanent magnets 172 are located below the magnetic conducting piece 171, i.e. close to the induction cooker 200, and at the same time, the position between the two permanent magnets 172 has the maximum magnetic property, so that the first magnetic component 170 can more easily automatically align and magnetically attract the second magnetic component 220 (which has the same structure as the first magnetic component 170) provided by the induction cooker 200.

[0047] At this time, all the first magnetic components 170 are arranged in a circumferential uniform manner around the center of the electromagnetic induction coil, and all the second magnetic components 220 are arranged in a circumferential uniform manner around the center of the heating coil disc 230 of the induction cooker 200. When the first magnetic component 170 and the second magnetic component 220 are in one-to-one correspondence and automatically aligned and attracted, the electromagnetic induction coil provided by the pot support 110 and the heating coil disc 230 of the induction cooker 200 are concentrically arranged.

[0048] In the embodiment, as shown in Figure 1As shown, the first magnetic components 170 are provided in three, and the three first magnetic components 170 are arranged at intervals at an angle of 120° around the center of the electromagnetic induction coil. The permanent magnets 172 are magnetic steel, which has strong magnetism and can keep the magnetism unchanged for a long time. The permanent magnets 172 are in a cylindrical shape. All the permanent magnets 172 are located on the same circumference of the electromagnetic induction coil.

[0049] Of course, it is not excluded that in other embodiments, all the permanent magnets 172 with the N-pole direction downward are located on the same circumference of the electromagnetic induction coil, and all the permanent magnets 172 with the N-pole direction upward are located on another circumference of the electromagnetic induction coil.

[0050] As shown in the figure, Figure 1 The pot support 110 is provided with a receiving cavity, and the electromagnetic induction coil and the first magnetic components 170 are arranged in the receiving cavity. Specifically, the pot support 110 is in a circular ring shape and is coaxially arranged with the electromagnetic induction coil. The pot support 110 includes an upper shell 111 and a lower shell 112, and the upper shell 111 and the lower shell 112 can be connected by screws 180. The lower shell 112 is provided with a receiving groove 114 with an upwardly open opening, and the receiving groove 114 is in a circular ring shape. The electromagnetic induction coil is installed in the receiving groove 114. The lower shell 112 is also provided with a mounting groove 113 with an upwardly open opening. The shape of the mounting groove 113 is matched with the shape of the permanent magnet 172, and the permanent magnet 172 can be embedded in the mounting groove 113. The magnetic conductive piece 171 is located outside the mounting groove 113. All the mounting grooves 113 are located on the outside of the receiving groove 114, and all the mounting grooves 113 are circumferentially and uniformly arranged around the center of the receiving groove 114.

[0051] In the embodiment, as shown in the figure, Figure 1 From the center axis of the electromagnetic induction coil, the magnetic conductive piece 171 is in a circular arc shape, and all the magnetic conductive pieces 171 and all the permanent magnets 172 are located on the same circumference of the electromagnetic induction coil.

[0052] In some embodiments, when the number of the first magnetic components 170 is odd or even, for any two adjacent first magnetic components 170, the magnetic pole directions of the two permanent magnets 172 close to each other are opposite, such as one of the permanent magnets 172 is arranged with the N-pole downward, and the other permanent magnet 172 is arranged with the N-pole upward.

[0053] In other embodiments, the first magnetic components 170 are provided with an even number, and for any two adjacent first magnetic components 170, the magnetic pole directions of the two permanent magnets 172 close to each other are the same, such as one of the permanent magnets 172 is arranged with the N-pole downward, and the other permanent magnet 172 is also arranged with the N-pole downward.

[0054] In some embodiments, as shown in the figure, Figures 1 to 4As shown, the pot support 110 is further provided with at least three support portions 120, all of which are arranged uniformly in a circle around the central axis of the electromagnetic induction coil, and each of the support portions 120 is provided with a support inclined surface 121 for contacting the non-flat-bottomed pot, and at least part of the support inclined surface 121 is provided with a temperature measuring sensor 130.

[0055] It can be understood that the support inclined surfaces 121 on all of the support portions 120 can exert a supporting action on the non-flat-bottomed pot, and the included angle between the support inclined surface 121 and the horizontal plane can be 30°, 45° or 60°, etc. The inclination angle of the support inclined surface 121 can be selected according to actual needs, which is not specifically limited here. The temperature measuring sensor 130 is protrudingly arranged on the support inclined surface 121 of the support portion 120, and the temperature measuring sensor 130 can be in direct contact with the pot. The support portion 120 is provided with a mounting hole for mounting the temperature measuring sensor 130, and the temperature measuring sensor 130 can be electrically connected with the electromagnetic induction coil in the accommodating cavity. The temperature measuring sensor 130 can be arranged on each of the support portions 120, or the temperature measuring sensor 130 can be arranged on part of the support portions 120.

[0056] In the present embodiment, the number of the support portions 120 is four, and they are arranged at intervals according to an angle of 90° around the central axis of the electromagnetic induction coil.

[0057] Further, the support portion 120 is further provided with a support flat surface 122 for contacting the flat-bottomed pot, the support flat surface 122 is located above the support inclined surface 121, and the support flat surface 122 is located outside the support inclined surface 121. At least part of the support flat surface 122 is provided with a temperature measuring sensor 130. The temperature measuring sensor 130 is protrudingly arranged on the support flat surface 122 of the support portion 120.

[0058] It can be understood that such a design increases the versatility of the magnetic pot rack 100, making it applicable to flat-bottomed pots and non-flat-bottomed pots, and avoiding the pot being placed directly on the stove surface 210 of the electromagnetic oven 200. In the present embodiment, in the case of four support portions 120, the support flat surfaces 122 of two support portions 120 symmetrically arranged about the central axis of the electromagnetic induction coil are provided with temperature measuring sensors 130 for accurately measuring the temperature data of the flat-bottomed pot, and the support inclined surfaces 121 of the other two support portions 120 are provided with temperature measuring sensors 130 for collecting the temperature data of the non-flat-bottomed pot.

[0059] In some embodiments, the pot support 110 is further provided with a control unit 160 and a wireless communication unit. The wireless communication unit, the temperature measuring sensor 130 and the electromagnetic induction coil are electrically connected to the control unit 160 through wires. The wireless communication unit is configured to wirelessly transmit the temperature data collected by the temperature measuring sensor 130 to the induction cooker 200. The electromagnetic induction coil is further configured to supply power to the wireless communication unit, the temperature measuring sensor 130 and the control unit 160.

[0060] It can be understood that the wireless communication unit can adopt a wireless transmission module such as an RF (Radio Frequency) module, which can use wireless radio frequency transmission to transmit signals. The control unit 160 can adopt an integrated mainboard, a PLC controller or a 51 single-chip microcomputer, etc. When the magnetic pot support 100 is placed on the induction cooker 200, the induction cooker 200 is started, and the electromagnetic induction coil can generate a certain current due to the electromagnetic induction generated by the induction cooker 200 and send it to the control unit 160. The control unit 160 can rectify, filter and stabilize the current, etc. to distribute the current to the temperature measuring sensor 130 and the wireless communication unit, so that the temperature measuring sensor 130 can effectively collect the temperature data of the pot and transmit it to the control unit 160. The wireless communication unit wirelessly transmits the temperature data received by the control unit 160, so that the induction cooker 200 can receive the temperature data through the wireless communication module configured by itself. The wireless communication module can be wirelessly connected to the wireless communication unit through a Bluetooth connection mode and can complete the mutual transmission of data.

[0061] In some embodiments, as shown in Figures 1 to 4 The pot support 110 is further provided with a light-transmitting plate assembly and a light-emitting assembly 150. The light-transmitting plate assembly is coaxially arranged with the electromagnetic induction coil, and the light-emitting assembly 150 is oppositely arranged with the light-transmitting plate assembly. The light-emitting assembly 150 is configured to emit light towards the light-transmitting plate assembly, so that the light can pass through the light-transmitting plate assembly and be emitted outward.

[0062] The light-emitting assembly 150 is electrically connected to the control unit 160 through wires. The electromagnetic induction coil is further configured to supply power to the light-emitting assembly 150. Moreover, the control unit 160 is configured to control the brightness of the light-emitting assembly 150 to increase according to the increase of the power of the induction cooker 200 or the increase of the temperature data collected by the temperature measuring sensor 130.

[0063] It can be understood that the light-transmitting plate assembly can be made of acrylic material, and the light-emitting assembly 150 can adopt an LED lamp panel including a plurality of LED lamp beads. The LED lamp beads can be single-color lamp beads capable of emitting red or blue light, or multi-color lamp beads capable of switching the color of light according to requirements. The control unit 160 can distribute the current generated by the electromagnetic induction coil to the light-emitting assembly 150, so that the light-emitting assembly 150 can work normally.

[0064] In some examples, the control unit 160 can control the light brightness of the light-emitting assembly 150 according to the size of the received temperature data. When the temperature data is larger, the light brightness is stronger, and when the temperature data is smaller, the light brightness is weaker. In other examples, the control unit 160 can control the light brightness of the light-emitting assembly 150 according to the size of the output power received from the induction cooker 200. When the output power of the induction cooker 200 is larger, the light brightness is stronger, and when the output power of the induction cooker 200 is smaller, the light brightness is weaker.

[0065] Of course, it is not excluded that in other embodiments, the control unit 160 and the induction cooker 200 are not wirelessly connected. When the output power of the induction cooker 200 increases, the leakage electromagnetic waves collected by the electromagnetic induction coil from the heating coil disc 230 of the induction cooker 200 increase, so that the induced electromotive force generated by the electromagnetic induction coil increases, and the output power of the control unit 160 input to the light-emitting assembly 150 increases, so that the light intensity of the light-emitting assembly 150 increases.

[0066] When the induction cooker 200 is working, the electromagnetic induction coil on the magnetic pot support 100 can induce the magnetic field (leakage magnetic energy) of the heating coil disc 230 on the induction cooker 200, and then generate an induced current to provide power for the control unit 160, the wireless communication unit, the light-emitting assembly 150, and the temperature sensor 130.

[0067] In a specific embodiment, as shown in Figures 1 to 4 The light-transmitting plate assembly is provided with a plurality of light-transmitting plates 140, which are arranged in a circle around the central axis of the electromagnetic induction coil. In addition, the light-transmitting plate 140 avoids the support part 120, that is, there is at least one light-transmitting plate 140 between any two adjacent support parts 120. The light-emitting assembly 150 is located below the light-transmitting plate 140, and the light-emitting assembly 150 can emit light upward.

[0068] It can be understood that when the light-emitting assembly 150 is running, the light-emitting assembly 150 can emit light simulating a flame, the light can pass through the corresponding light-transmitting plate 140 and directly irradiate on the pot, so that the user can more intuitively observe the light condition, thereby truly simulating the display of the increase of the firepower of the induction cooker 200, realizing the visual display of the firelight, and making the user experience better. In the embodiment, the number of the light-transmitting plates 140 is four, and correspondingly, the light-emitting assembly 150 can include four LED lamp plates.

[0069] Of course, it is not excluded that in other embodiments, the light-transmitting plate assembly is one light-transmitting plate 140 in the form of a circular ring and is arranged on the outer peripheral surface of the pot support 110 or on the upper surface of the pot support 110 and below the support part 120.

[0070] In the magnetic pot support 100 provided in the first aspect of the present application, the pot support 110 is provided with a plurality of first magnetic components 170 which are arranged in a circle around the central axis of the electromagnetic induction coil and are uniformly arranged in a circle. In the structure of the first magnetic component 170, two permanent magnets 172 with opposite magnetic poles are arranged at opposite ends of the magnetic conductor 171, so that the two permanent magnets 172 and the magnetic conductor 171 can jointly form a magnetic force circle. In this way, the magnetic field strength of the first magnetic component 170 can be increased. At the same time, the magnetic property of the position between the two permanent magnets 172 is the strongest, i.e. the magnetic property of the opening position of the first magnetic component 170 is the strongest. Moreover, the two permanent magnets 172 are located on the side of the magnetic conductor 171 away from the temperature sensor 130 in the first direction, i.e. the opening position of the first magnetic component 170 is arranged downward, and the two permanent magnets 172 are arranged close to the second magnetic component 220 which is arranged in the same structure as the first magnetic component 170.

[0071] Then, when the user places the magnetic pot support 100 on the stove surface 210 of the induction cooker 200, in the case of a large magnetic field strength, the plurality of first magnetic components 170 on the magnetic pot support 100 can automatically move in a small range on the stove surface 210 of the induction cooker 200, so as to make the plurality of first magnetic components 170 correspond one by one and automatically align and adsorb with the plurality of second magnetic components 220 arranged on the induction cooker 200, so that the magnetic force lines between the first magnetic component 170 and the second magnetic component 220 can form a closed loop, as shown by the dashed line in Figure 8 In this way, the magnetic effect can be enhanced, the fixing effect of the magnetic pot support 100 can be improved, and the magnetic pot support 100 is less likely to deviate in position. Moreover, the magnetic pot support 100 can be accurately placed on the stove surface 210 of the induction cooker 200, so that the electromagnetic induction coil and the heating coil disc 230 of the induction cooker 200 are arranged in a concentric manner, thereby improving the installation simplicity and accuracy of the magnetic pot support 100.

[0072] AsFigures 1 to 8 As shown, the electromagnetic oven assembly according to the second aspect of the present application comprises the electromagnetic oven 200 and the magnetic pot rack 100 of the first aspect of the present application.

[0073] The electromagnetic oven 200 has an oven surface 210 and a heating coil disc 230, wherein the heating coil disc 230 is located below the oven surface 210. It can be understood that the electromagnetic oven 200 adopts a microcrystalline glass plate as the oven surface 210, and the heating coil disc 230 is built-in in the electromagnetic oven 200, and the heating coil disc 230 realizes direct heating of the pot by the principle of electromagnetic induction eddy current. The central axis of the heating coil disc 230 extends along the first direction.

[0074] Moreover, the electromagnetic oven 200 is provided with a plurality of second magnetic components 220, all of which are located below the oven surface 210, and the plurality of second magnetic components 220 are uniformly arranged in a circle around the central axis of the heating coil disc 230. The second magnetic components 220 are consistent with the first magnetic components 170 in structure, and the second magnetic components 220 are also consistent with the first magnetic components 170 in number. The second magnetic components 220 and the first magnetic components 170 can be one-to-one corresponding, and the second magnetic components 220 are configured to be magnetically attracted with the first magnetic components 170 to form a closed-loop magnetic field line loop, as shown. Figure 8

[0075] In the present embodiment, the magnetic pot rack 100 is provided with three first magnetic components 170, which are uniformly arranged at intervals according to an angle of 120° around the central axis of the electromagnetic induction coil. The electromagnetic oven 200 is provided with three second magnetic components 220, which are uniformly arranged at intervals according to an angle of 120° around the central axis of the heating coil disc 230. Therefore, each first magnetic component 170 can be automatically adsorbed with the corresponding second magnetic component 220, ensuring that the magnetic pot rack 100 is accurately placed on the electromagnetic oven 200.

[0076] It can be understood that the second magnetic component 220 comprises a magnetic conducting strip 221 and a permanent magnet block 222, the permanent magnet block 222 is located above the magnetic conducting strip 221 and is fixedly connected with the magnetic conducting strip 221, the magnetic conducting strip 221 is provided with the permanent magnet block 222 at opposite ends in the horizontal direction, and the magnetic poles of the two permanent magnet blocks 222 are opposite. The permanent magnet block 222 can be a cylindrical magnetic steel. Specifically, one of the permanent magnet blocks 222 is provided with an N-pole upward, and the other permanent magnet block 222 is provided with an N-pole downward.

[0077] ​In the structure of the second magnetic component 220, the two permanent magnet blocks 222 with opposite magnetic pole directions are arranged at opposite ends of the magnetic conducting strip 221, so that the two permanent magnet blocks 222 and the magnetic conducting strip 221 can jointly form a magnetic force circle, thus increasing the magnetic field strength of the second magnetic component 220. Meanwhile, the magnetic property at the position between the two permanent magnet blocks 222 is the strongest, i.e. the magnetic property at the opening position of the second magnetic component 220 is the strongest, and the two permanent magnet blocks 222 are located at the side of the magnetic conducting strip 221 close to the stove surface 210 in the first direction, i.e. the opening position of the second magnetic component 220 is arranged upward, so that the two permanent magnet blocks 222 are close to the first magnetic component 170 of the magnetic pot rack 100.

[0078] Then, as shown in Figure 8 When one of the first magnetic components 170 and one of the second magnetic components 220 are arranged in an up-down corresponding manner, the N pole of one of the permanent magnet pieces 172 in the first magnetic component 170 is opposite to the S pole of one of the permanent magnet blocks 222 in the second magnetic component 220, and magnetic attraction is generated, and meanwhile, the S pole of the other permanent magnet piece 172 in the first magnetic component 170 is opposite to the N pole of the other permanent magnet block 222 in the second magnetic component 220. Therefore, a magnetic force line closed loop can be formed between each of the first magnetic components 170 and each of the second magnetic components 220, thus enhancing the magnetic effect and making the magnetic pot rack 100 more stably fixed on the stove surface 210 of the electromagnetic stove 200. Meanwhile, under the action of the strong magnetic field, the first magnetic component 170 and the second magnetic component 220 can be automatically aligned and adsorbed, realizing automatic and accurate positioning of the magnetic pot rack 100 on the stove surface 210 of the electromagnetic stove 200, and ensuring that the electromagnetic induction coil and the heating coil disc 230 are coaxially arranged.

[0079] In addition, the first magnetic component 170 and the second magnetic component 220 adopt the above structure design, and also have the advantage of small occupied volume, which can avoid the upper and lower sizes of the magnetic pot rack 100 and the electromagnetic stove 200 being too large.

[0080] In the electromagnetic oven assembly provided by the second aspect of the utility model, when the magnetic pot rack 100 is placed on the oven surface 210 of the electromagnetic oven 200, because there is a strong magnetic field strength between the first magnetic components 170 and the second magnetic components 220, the plurality of first magnetic components 170 on the magnetic pot rack 100 can easily automatically align and be adsorbed with the plurality of second magnetic components 220 on the electromagnetic oven 200, so that the electromagnetic induction coil on the magnetic pot rack 100 and the heating coil disc 230 of the electromagnetic oven 200 can be coaxially arranged, the magnetic pot rack 100 is accurately positioned and installed on the electromagnetic oven 200, and meanwhile, the magnetic force line loop formed between the first magnetic components 170 and the second magnetic components 220 is closed, and the magnetic attraction between the magnetic pot rack 100 and the electromagnetic oven 200 is further enhanced, and the fixing effect on the magnetic pot rack 100 is improved.

[0081] When the magnetic pot rack 100 needs to be detached from the electromagnetic oven 200, the user can horizontally rotate the magnetic pot rack 100, so that the first magnetic components 170 and the second magnetic components 220 are misaligned, the magnetic attraction between them is reduced, and the magnetic pot rack 100 is removed from the electromagnetic oven 200. Specifically, the N-pole downward permanent magnet 172 in the first magnetic component 170 can be rotated to be opposite to the N-pole upward permanent magnet 222 in the second magnetic component 220, and by using the same-pole repulsion effect, the magnetic pot rack 100 can be easily detached.

[0082] In addition, the position and magnetic pole of the permanent magnet 172 can be marked on the outer circumferential surface of the pot support 110, so that the user can more intuitively and clearly know the condition of the permanent magnet 172.
