[0057] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0058] When the electromagnetic cooker integrates the weighing function in the design, some challenges will be faced. In order to realize the weighing function, the panel needs to form a cantilever beam structure, so that there is a gap between the panel and the installation countertop, thereby affecting the waterproof and anti-fouling performance.

[0059] Therefore, the cooking equipment provided by the present application can separate the weighing and non-weighing scenes according to the use needs of the user. When weighing is needed, the lifting unit lifts up the panel, the gravity of the object acts on the panel, the panel acts the force on the lifting unit, and the lifting unit transmits the force to the corresponding weight detection assembly. In the whole process, contact with other parts is avoided, the force can be effectively transmitted to the weight detection assembly, and the accuracy of the weighing measurement is improved. After the lifting unit lifts up the panel, a gap appears between the panel and the installation countertop. By arranging the sealing structure between the panel and the installation countertop, the sealing structure can effectively block the liquid flowing along the surface of the panel into the cooking equipment, protect the parts inside the cooking equipment from being damaged by moisture and oil stains, maintain the cleanliness inside the cooking equipment, and help to ensure the service life of the cooking equipment.

[0060] The cooking equipment provided by the embodiments of the present application will be described below with reference to the drawings.

[0061] Reference Figure 1 , Figure 2 and Figure 3 As shown in FIGS. 1 to 3, the present application provides a cooking equipment embedded in the installation groove 71 formed in the installation countertop 70. The cooking equipment comprises:

[0062] A bottom shell 10 embedded in the installation groove 71, and the bottom shell 10 has a receiving cavity 11 therein;

[0063] A lifting assembly comprising a lifting unit 20 and a panel 30. The lifting unit 20 is arranged in the receiving cavity 11, and the panel 30 is connected to the top end of the lifting unit 20 and covers the installation groove 71;

[0064] A weight detection assembly 40 connected between the bottom shell 10 and the lifting assembly. The lifting unit 20 is used to make the panel 30 in a lifted state away from the bottom shell 10 when weighing, and make the panel 30 in a fallen state covering the bottom shell 10 when cooking;

[0065] A sealing structure 50 is arranged between the panel 30 and the mounting table 70.

[0066] The cooking device provided by the present application has the function of weighing by arranging the lifting unit 20 in the accommodating cavity 11, connecting the panel 30 to the top end of the lifting unit 20, and connecting the weight detection assembly 40 between the bottom shell 10 and the lifting assembly.

[0067] When weighing is needed, the lifting unit 20 lifts the panel 30, so that the panel 30 is in a lifted state away from the bottom shell 10, the gravity of the object acts on the panel 30, the panel 30 transmits the force to the lifting unit 20, and the lifting unit 20 transmits the force to the corresponding weight detection assembly 40. In the whole process, contact with other parts is avoided, the force can be effectively transmitted to the weight detection assembly 40, and the accuracy of weighing measurement is improved. After the lifting unit 20 lifts the panel 30, a gap is formed between the panel 30 and the mounting table 70. By arranging the sealing structure 50 between the panel 30 and the mounting table 70, the sealing structure 50 can effectively prevent the liquid on the upper surface of the panel 30 from flowing into the interior of the cooking device along the lower surface of the panel from the edge of the panel 30, protect the parts inside the cooking device from moisture and oil stains, and keep the interior of the cooking device clean, which helps to ensure the service life of the cooking device.

[0068] The cooking device provided by the present application is embedded in the mounting groove 71 formed in the mounting table 70. The mounting table 70 may, for example, be a table top, a cabinet platform, etc. This embedded design can more effectively utilize the kitchen space, reduce the height of the cooking device protruding from the mounting table 70, reduce the problem of collision, facilitate to provide a flat mounting table 70, reduce the visual clutter, and improve the aesthetic sense of the overall kitchen design.

[0069] The bottom shell 10 serves to support the whole cooking device, and the accommodating cavity 11 is used to accommodate the lifting unit 20, so as to ensure that the lifting unit 20 has enough movement space in the vertical direction.

[0070] In a possible implementation manner, as shown in Figure 1 and Figure 2 The weight detection assembly 40 includes a strain gauge 41 connected between the bottom shell 10 and the lifting unit 20, which is used to realize high-precision weight measurement. Figure 2 and Figure 5 The weight detection assembly 40 can measure the weight or mass of an object, which can be realized by converting physical force into an electrical signal.

[0071] When weighing is required, the lifting unit 20 lifts the panel 30, placing it in a raised state detached from the base shell 10. The weight of the object placed on the panel 30 acts on it, and the panel 30 exerts a force on the lifting unit 20, causing deformation. The strain gauge 41 measures the load change borne by the lifting unit 20, resulting in a change in resistance. This change is converted into an electrical signal. The change in resistance of the strain gauge 41 causes a change in its potential, generating a potential difference. This potential difference signal is transmitted to the control board of the cooking equipment via a wire. The control board can calculate the applied pressure, i.e., the weight of the object placed on the panel 30, using the potential difference to calculate the weight. The strain gauge 41 needs to have good elasticity and durability to ensure its stability during long-term use.

[0072] In one possible implementation method, refer to Figure 1 and Figure 2 As shown, panel 30 covers mounting groove 71. Panel 30 provides a flat surface that can be used to protect the internal components of the cooking device and to keep the top of the cooking device flat.

[0073] In one possible implementation method, refer to Figure 4 As shown, the bottom shell 10 includes a bottom shell body 14 and a flange structure 12 connected to the top edge of the bottom shell body 14. The sealing structure 50 is arranged around the periphery of the bottom shell body 14, which can effectively prevent moisture, oil stains and other substances from seeping into the interior of the cooking equipment from the periphery gaps of the bottom shell body 14, thereby preventing problems such as corrosion of parts and short circuits.

[0074] In one possible implementation, the bottom shell body 14 may be cubic in shape, and the bottom wall of the bottom shell body 14 is provided with heat dissipation holes 13. There may be multiple heat dissipation holes 13, which is beneficial for timely ventilation and heat dissipation of the cooking equipment when it is working.

[0075] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 3 As shown, the sealing structure 50 includes a first sealing ring 51, which is disposed on the lower surface of the panel 30. When the panel 30 is in the fallen state, the panel 30 covers the bottom shell 10, and the first sealing ring 51 abuts against the mounting platform 70.

[0076] The first sealing ring 51 is annular, and a central hole 511 is formed in the first sealing ring 51. In a direction perpendicular to the installation table 70, a projection of the installation groove 71 is located within a projection range of the central hole 511. The first sealing ring 51 forms a first heavy waterproof structure, and can effectively block liquid such as water droplets flowing down from the upper surface edge of the panel 30, so as to prevent the liquid from entering the inside of the cooking device and the installation groove 71 through the first sealing ring 51, and make the liquid drop downwardly to the installation table 70.

[0077] In a possible implementation, the first sealing ring 51 is arranged at the edge of the lower surface of the panel 30, so as to block liquid such as water droplets falling on the panel 30 at the edge of the panel 30, thereby preventing the liquid such as water droplets falling on the panel 30 from flowing along the edge of the panel 30 to the lower surface of the panel 30, and facilitating cleaning and wiping of the liquid such as water droplets falling on the panel 30.

[0078] In a possible implementation, the first sealing ring 51 can be made of an elastic material, such as silica gel, rubber or polyurethane material, and has good elasticity and durability.

[0079] In a possible implementation, the shape and size of the first sealing ring 51 should match the lower surface of the panel 30 and the covered area, so as to ensure good waterproof effect. The first sealing ring 51 should be firmly fixed to the lower surface of the panel 30, for example, the first sealing ring 51 can be attached to the lower surface of the panel 30 by an adhesive or the like, so as to avoid displacement or falling of the first sealing ring 51 during use.

[0080] When the panel 30 is in the falling state, the panel 30 covers the bottom shell 10, and the first sealing ring 51 abuts against the installation table 70, so that the gap between the panel 30 and the installation table 70 is filled by the first sealing ring 51, thereby effectively preventing water flow, oil stains and the like from entering the inside of the cooking device through the gap between the panel 30 and the installation table 70, and protecting the internal components of the cooking device from corrosion and pollution.

[0081] In a possible implementation, as shown in Figure 1 , Figure 2 and Figure 3 , the folded edge structure 12 includes a first folded edge 121 connected to the top edge of the bottom shell body 14, and the sealing structure 50 further includes a sealing stop protrusion 52 connected to the first folded edge 121, wherein the sealing stop protrusion 52 protrudes downwardly from the first folded edge 121, and the sealing stop protrusion 52 abuts against the installation table 70.

[0082] The sealing protrusion 52 forms a second heavy waterproof structure, which aims to enhance the sealing performance between the panel 30 and the mounting table 70, effectively blocks the liquid, dust or other contaminants from entering the interior of the cooking equipment, improves the protection performance of the cooking equipment, and guarantees the service life of the cooking equipment. In addition, the sealing protrusion 52 can also improve the overall stability of the bottom shell 10.

[0083] In a possible implementation manner, referring to Figure 4 As shown, the top of the bottom shell 10 is open, and the flange structure 12 is connected to the outer edge of the opening. The flange structure 12 can be held by a user to facilitate disassembly and assembly of the bottom shell 10. The flange structure 12 also helps to enhance the rigidity and strength of the bottom shell 10 to prevent deformation of the bottom shell 10.

[0084] In a possible implementation manner, the bottom shell body 14, the flange structure 12 and the sealing protrusion 52 can be an integral structure.

[0085] In a possible implementation manner, the sealing protrusion 52 has a groove 521 inside, and the groove 521 has an opening facing the panel 30. In this example, the longitudinal section of the sealing protrusion 52 can be U-shaped or the like.

[0086] In a possible implementation manner, referring to Figure 1 , Figure 2 and Figure 3 The sealing protrusion 52 is in surface contact with the mounting table 70.

[0087] The sealing protrusion 52 forms an effective sealing barrier. Compared with line contact, surface contact has a larger contact area. By expanding the contact area between the sealing protrusion 52 and the mounting table 70, the stability of the sealing between the sealing protrusion 52 and the mounting table 70 can be improved, and the stability of the sealing can be enhanced. In addition, the surface contact also makes the pressure between the sealing protrusion 52 and the mounting table 70 evenly distributed on the entire contact surface, preventing the problem of material wear and deformation caused by excessive local pressure due to too small contact area, thereby prolonging the service life of the sealing protrusion 52 and maintaining long-term stable sealing effect.

[0088] In a possible implementation manner, the flange structure 12 further includes a second flange 122, and the second flange 122 and the first flange 121 are respectively connected to opposite sides of the sealing protrusion 52.

[0089] Such a structure makes the second flange 122 and the first flange 121 form bilateral symmetrical support for the sealing protrusion 52, which is conducive to improving the overall structural strength of the flange structure 12, avoiding deformation of the sealing protrusion 52 due to external force or long-term use, and ensuring that the sealing protrusion 52 always maintains a stable contact area with the mounting table 70, thereby maintaining stable waterproof, dustproof and oil stainproof effect.

[0090] In a possible implementation manner, the first flange 121, the sealing protrusion 52, the second flange 122 and the bottom shell body 14 can be an integral structure.

[0091] In a possible implementation manner, the sealing protrusion 52 is located between the first sealing ring 51 and the mounting groove 71. Reasonable layout makes the sealing protrusion 52 and the first sealing ring 51 form a double protection barrier, reducing the problem of sealing failure caused by single component failure.

[0092] In a possible implementation manner, the first sealing ring 51 and the sealing protrusion 52 are arranged at intervals. The gap between the first sealing ring 51 and the sealing protrusion 52 provides possible deformation space for the first sealing ring 51.

[0093] The embodiment of the present application provides a cooking device. When the bottom shell 10 is installed in the mounting groove 71 of the mounting table 70, when the weighing function is not started, under the gravity of the cooking device itself, the sealing protrusion 52 abuts against the upper surface of the mounting table 70, and the first sealing ring 51 abuts against the upper surface of the mounting table 70, and a double waterproof effect is formed by the first sealing ring 51 and the sealing protrusion 52, thereby improving the sealing performance.

[0094] When the weighing function of the cooking device is started, the lifting unit 20 lifts the panel 30, so that the panel 30 is in a lifted state of being separated from the bottom shell 10, the distance between the panel 30 and the mounting table 70 is increased, and the first sealing ring 51 is separated from the upper surface of the mounting table 70. When water flows down the panel 30, the first sealing ring 51 can prevent water from flowing into the cooking device along the edge of the panel 30, and plays a role of blocking water flow and the like, so that the water flow and the like flow to the mounting table 70. At the same time, the sealing protrusion 52 still abuts against the mounting table 70, the sealing protrusion 52 is tightly sealed with the mounting table 70, and water on the mounting table 70 is prevented from entering the cooking device, thereby realizing a double waterproof effect.

[0095] In a possible implementation manner, the number of the first sealing ring 51 can also be two, three or more. The two, three or more first sealing rings 51 are concentrically arranged, which is helpful to improve the sealing effect.

[0096] In a possible implementation manner, as shown in Figure 2 , Figure 6 and Figure 7 , the lifting unit 20 comprises a base 21, a bidirectional screw nut mechanism 22, a first force arm 23 and a second force arm 24, and the base 21 is located in the accommodating cavity 11.

[0097] As shown in Figure 2 , Figure 6 and Figure 7 , the bidirectional screw nut mechanism 22 comprises a screw rod 221 and a nut 222.As shown, the bidirectional screw-nut mechanism 22 comprises a screw 221, a first nut member 222 and a second nut member 223. The screw 221 is rotatably arranged on the base 21. The screw 221 has a first threaded section 2211 and a second threaded section 2212 at opposite ends thereof. The first threaded section 2211 and the second threaded section 2212 have opposite screw directions. The first nut member 222 is threadedly engaged with the first threaded section 2211. The second nut member 223 is threadedly engaged with the second threaded section 2212. One end of the first force arm 23 is rotatably connected to the first nut member 222. The other end of the first force arm 23 is rotatably connected to the panel 30. One end of the second force arm 24 is rotatably connected to the second nut member 223. The other end of the second force arm 24 is rotatably connected to the panel 30.

[0098] The first nut member 222 and the second nut member 223 move towards or away from each other along the axial direction of the screw 221, so as to move the panel 30 in the vertical direction by the first force arm 23 and the second force arm 24.

[0099] The base 21 serves as a support structure of the entire lifting unit 20, and provides a stable support base to support the screw 221.

[0100] In one possible implementation, referring to Figure 1 As shown, the panel 30 comprises a connecting table 31 and a bearing plate 32. The bearing plate 32 can be placed on the connecting table 31, or can be connected to the connecting table 31 by means of glue or welding. In this way, the force applied by the object on the panel 30 is fully applied to the entire lifting unit 20, thereby improving the weighing accuracy.

[0101] In one possible implementation, referring to Figure 2 、 Figure 6 and Figure 7 As shown, the screw 221 is rotatably arranged on the base 21. The screw 221 has a first threaded section 2211 and a second threaded section 2212 at opposite ends thereof. The first threaded section 2211 and the second threaded section 2212 have opposite screw directions. The first nut member 222 is threadedly engaged with the first threaded section 2211. The second nut member 223 is threadedly engaged with the second threaded section 2212.

[0102] In one possible implementation, one end of the first force arm 23 is rotatably connected to the first nut member 222. The other end of the first force arm 23 is rotatably connected to the connecting table 31. One end of the second force arm 24 is rotatably connected to the second nut member 223. The other end of the second force arm 24 is rotatably connected to the connecting table 31.

[0103] Since the screw thread directions of the first threaded section 2211 and the second threaded section 2212 are opposite, when the screw rod 221 rotates, the first nut member 222 and the second nut member 223 move towards or away from each other along the axial direction of the screw rod 221.

[0104] The first nut member 222 is screwed with the first threaded section 2211, and the second nut member 223 is screwed with the second threaded section 2212. Since the screw thread transmission has self-locking characteristics, the first nut member 222 and the second nut member 223 can remain stationary when the driving is stopped, thereby ensuring the position stability of the panel 30 and increasing the safety in use.

[0105] In a possible implementation, the screw rod 221 is arranged transversely on the base 21, both ends and the middle section of the screw rod 221 extend into the interior of the base 21, bearings are arranged between the both ends of the screw rod 221 and the base 21, and bearings are arranged between the middle section of the screw rod 221 and the base 21, thereby ensuring the smooth rotation of the screw rod 221.

[0106] In a possible implementation, the pitches of the first threaded section 2211 and the second threaded section 2212 are equal, and when the screw rod 221 rotates one round, the first nut member 222 and the second nut member 223 move along the axial direction of the screw rod 221 by the same distance.

[0107] In a possible implementation, the number of the first force arms 23 is two, and the two first force arms 23 are respectively rotatably connected between the two sides of the first nut member 222 and the connecting table 31. The number of the second force arms 24 is two, and the two second force arms 24 are respectively rotatably connected between the two sides of the second nut member 223 and the connecting table 31, thereby helping to improve the stability of the lifting movement of the connecting table 31.

[0109] It should be noted that the above-mentioned rotatable connection can be achieved by shaft hole cooperation, for example, a rotating hole is formed at each end of the first force arm 23, and a rotating shaft is connected to the two sides of the first nut member 222, and the rotating shaft is extended into the rotating hole to achieve the rotatable connection.

[0110] In a possible implementation, in order to achieve the rotatable connection between the first force arm 23 and the connecting table 31, a first lug 311 is fixedly connected to the lower surface of the connecting table 31, and the first force arm 23 can be rotatably connected to the first lug 311 through a pin shaft. In order to achieve the rotatable connection between the second force arm 24 and the connecting table 31, a second lug 312 is fixedly connected to the lower surface of the connecting table 31, and the second force arm 24 can be rotatably connected to the second lug 312 through a pin shaft.

[0111] In a possible implementation, as shown in Figure 1 , Figure 2 and Figure 7 , the base 21 further comprises a leg portion 211, a guide hole 2111 is formed in the leg portion 211, the bottom of the connecting table 31 is connected with a guide column 313, the guide column 313 extends into the guide hole 2111, and through the cooperation of the guide column 313 and the guide hole 2111, the panel 30 can be better guided to move up and down, and the panel 30 can be prevented from being skewed or stuck during the up and down movement.

[0112] In a possible implementation, the number of the leg portions 211 is at least two, and the base 21 further comprises a cross beam 212 connected between two adjacent leg portions 211, so as to improve the structural stability of the base 21.

[0113] In a possible implementation, the connecting table 31 is rectangular, and the number of the guide columns 313 can be four, the four guide columns 313 are respectively supported at four corner positions of the connecting table 31, so as to improve the stability of supporting the connecting table 31, and the number of the leg portions 211 is consistent with the number of the guide columns 313. Of course, the connecting table 31 can also have other shapes, for example, a circular shape, and the number of the guide columns 313 can also be other numbers, which are not limited here.

[0114] In a possible implementation, the guide hole 2111 and the guide column 313 have the same cross-sectional shape, for example, the guide hole 2111 is a circular hole, and the guide column 313 is in a cylindrical shape, or the guide hole 2111 is a rectangular hole, and the cross section of the guide column 313 is rectangular.

[0115] In a possible implementation, as shown in Figure 2 and Figure 10 , the accommodating cavity 11 of the bottom shell 10 is provided with a fixing seat 42, the fixing seat 42 can be screwed to the bottom shell 10, one end of the strain sheet 41 connected to the bottom shell 10 can be screwed to the fixing seat 42, and the other end of the strain sheet 41 can be connected to the bottom of the leg portion 211 by a fastener such as a screw, and the fixing seat 42 has a certain thickness, so that one end of the strain sheet 41 is lifted, and the strain sheet 41 has enough space to elastically deform.

[0116] In a possible implementation, as shown in Figure 1 , Figure 2 and Figure 6As shown, the cooking device further comprises a lifting driving assembly 90, which comprises a motor 91, a driving gear 92 and a driven gear 93. The motor 91 is arranged on the base 21. The driving gear 92 is arranged on the output shaft end of the motor 91. The driven gear 93 is arranged on the screw rod 221 and is in mesh with the driving gear 92.

[0117] The motor 91 drives the driving gear 92 to rotate, and the driving gear 92 drives the driven gear 93 to rotate, thereby transmitting power to the screw rod 221. The screw rod 221 rotates around its central axis. When the screw rod 221 rotates, the first nut member 222 and the second nut member 223 move along the axial direction of the screw rod 221.

[0118] In one possible implementation, when the first nut member 222 and the second nut member 223 move towards each other along the axial direction of the screw rod 221, the inclination of the first force arm 23 and the second force arm 24 gradually increases, thereby reducing the distance between the base 21 and the connecting table 31, and presenting the connecting table 31 in a downward movement along the vertical direction. When the first nut member 222 and the second nut member 223 move away from each other along the axial direction of the screw rod 221, the inclination of the first force arm 23 and the second force arm 24 gradually decreases, thereby increasing the distance between the base 21 and the connecting table 31, and presenting the connecting table 31 in an upward movement along the vertical direction.

[0119] In another possible implementation, when the first nut member 222 and the second nut member 223 move towards each other along the axial direction of the screw rod 221, the inclination of the first force arm 23 and the second force arm 24 gradually decreases, thereby increasing the distance between the base 21 and the connecting table 31, and presenting the connecting table 31 in an upward movement along the vertical direction. When the first nut member 222 and the second nut member 223 move away from each other along the axial direction of the screw rod 221, the inclination of the first force arm 23 and the second force arm 24 gradually increases, thereby reducing the distance between the base 21 and the connecting table 31, and presenting the connecting table 31 in a downward movement along the vertical direction.

[0120] In one possible implementation, referring to Figure 8 and Figure 9 As shown, the side wall of the leg part 211 is provided with a fixing hole 2112, which is in communication with the guide hole 2111.

[0121] In an embodiment, the cooking device further comprises a fixing assembly 60, which comprises a magnetic piece 61, an elastic piece 62, and an auxiliary support piece 63 movably arranged in the fixing hole 2112, the magnetic piece 61 is fixedly arranged on the base 21, the magnetic piece 61, the elastic piece 62, and the auxiliary support piece 63 are sequentially arranged along the moving direction of the auxiliary support piece 63, the two ends of the elastic piece 62 are respectively connected to the magnetic piece 61 and the auxiliary support piece 63, and the auxiliary support piece 63 is used to extend into the guide hole 2111 and is supported on the bottom of the guide column 313.

[0122] In an embodiment, the elastic piece 62 can be a spring or an elastic block.

[0123] In an embodiment, the top surface of the end of the auxiliary support piece 63 extending into the guide hole 2111 is beveled, which can guide the retraction of the auxiliary support piece 63 into the guide hole 2111.

[0124] When the connecting table 31 moves upward, the guide column 313 moves upward and leaves the fixing hole 2112, the elastic piece 62 pushes the auxiliary support piece 63 to extend into the guide hole 2111, and when the connecting table 31 is lifted to the top, the bottom of the guide column 313 abuts against the auxiliary support piece 63, the auxiliary support piece 63 supports the connecting table 31, and the weight is transmitted to the weight detection assembly 40 at the bottom of the leg part 211, so that the weight can be measured.

[0125] When the connecting table 31 moves downward, the guide column 313 pushes the auxiliary support piece 63 to retract into the fixing hole 2112, and the elastic piece 62 is in a compressed state.

[0126] In order to prevent the auxiliary support piece 63 from completely extending out of the guide hole 2111, the outer periphery of the auxiliary support piece 63 has a flange, which limits the movement of the auxiliary support piece 63 and prevents the auxiliary support piece 63 from completely extending out of the guide hole 2111.

[0127] In an embodiment, as shown in FIGS. 1-3, the weight detection assembly 40 comprises a load cell 41 and a support plate 42, the support plate 42 is arranged on the bottom of the leg part 211, and the load cell 41 is arranged on the support plate 42.

[0128] In an embodiment, the number of the weight detection assemblies 40 can be 4, and the four weight detection assemblies 40 are respectively connected to the bottoms of the four leg parts 211. ​

[0129] When the weighed object is placed at the eccentric position of the panel 30, for example, the edge position of the bearing plate 32, the center of the panel 30 is in the eccentric state, and because the connecting table 31 has a large support area, the pressure transmitted to the connecting table 31 is uniformly distributed, and the pressure is transmitted to the screw rod 221 and the leg portion 211 through the first force arm 23 and the second force arm 24, so that the pressure is uniformly dispersed on the leg portion 211 and uniformly transmitted to the strain gauge 41 of the weight detection assembly 40, which can effectively improve the weighing accuracy in the eccentric state.

[0135] During cooking, the pot is placed on the panel 30, and the working principle of the electromagnetic cooker is based on the electromagnetic induction phenomenon. An alternating magnetic field with a constantly changing direction is generated by using an alternating current through the coil in the coil disc. In the alternating magnetic field, eddy currents will appear inside the pot. When the electromagnetic cooker heats the iron pot, the panel 30 is in close contact with the heating disc 80, and the pot bottom is in close contact with the panel 30, so as to ensure the heating of the pot and improve the heating efficiency.

[0136] In a possible implementation manner, the embodiment of the present application provides a cooking device, which is an embedded weighing electromagnetic cooker with a wide weighing range, solves the problem of poor waterproof and antifouling performance of the existing weighing electromagnetic cooker, and improves the weighing accuracy of the existing weighing electromagnetic cooker.
