Description

Technical Field

[0001] The utility model discloses an electromagnetic cooking device, belonging to the technical field of electromagnetic cooking devices. Background Art

[0002] With the development and popularization of the small household appliance industry, electromagnetic cooking devices are deeply loved by consumers because of their advantages such as easy portability and fast heating. In order to meet the use of round-bottom cookware, the panel assembly of the electromagnetic cooking device includes a first panel and a concave panel. The first panel is provided with a mounting hole, and a part of the concave panel passes through the mounting hole and extends into the base of the electromagnetic cooking device. An electromagnetic coil disk is arranged in the base. The electromagnetic coil disk includes a coil bracket and a coil. The structure of the coil bracket matches that of the concave panel and also adopts a concave surface structure design.

[0003] However, since the concave panel is a ceramic glass panel, and the ceramic glass panel with a curved concave structure has weak strength and is prone to cracking during use, which will cause the electromagnetic coil disk to be directly exposed to the outside. In order to prevent users from accidentally touching the exposed electromagnetic coil disk and being scalded, existing electromagnetic cooking devices usually install a heat insulation plate above the electromagnetic coil disk.

[0004] However, during the use of the electromagnetic cooking device, the heat on the cookware will be conducted to the concave panel, and the temperature of the concave panel will reach more than 400 degrees, which is usually much higher than the heat resistance temperature of the heat insulation plate. Therefore, a heat insulation gap needs to be left between the concave panel and the heat insulation plate. However, in order not to affect the heating efficiency of the coil on the cookware, the heat insulation gap cannot be adjusted too large. Therefore, during the use of the electromagnetic cooking device, the heat insulation plate is easily deformed by the high temperature of the concave panel. After the heat insulation plate is deformed, it will bulge upward. When the bulged heat insulation plate touches the high-temperature area of the concave panel, the concave panel will be melted due to the high temperature, which is likely to cause potential safety hazards. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the heat insulation plate is easily melted due to high temperature after being deformed and contacting the concave panel. For this reason, an electromagnetic cooking device is provided, and the deformation amplitude of the heat insulation plate is restricted by a support structure to prevent the heat insulation plate from contacting the concave panel.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An electromagnetic cooking device includes a base, a panel assembly, and an electromagnetic coil disk. The electromagnetic coil disk is fixedly supported inside the base. The electromagnetic coil disk is wound with a coil. The panel assembly includes a first panel and a concave panel, and the mouth edge of the concave panel is mounted on the first panel. A heat insulation plate is installed on the side of the electromagnetic coil disk facing the concave panel. There is a heat insulation gap and a support structure between the concave panel and the heat insulation plate. The area of the concave panel facing the heat insulation plate includes a first support area near the lowest part of the concave panel, a second support area near the first panel, and a heat insulation area between the first support area and the second support area. The support structure is provided corresponding to the first support area and / or the second support area, and the heat insulation gap is at least provided corresponding to the heat insulation area.

[0008] The beneficial effects of adopting the utility model are as follows:

[0009] In the utility model, there is a support structure between the concave panel and the heat insulation plate. The two ends of the support structure respectively abut against the concave panel and the heat insulation plate. The support structure forms extrusion on the heat insulation plate, thereby restricting the upward convex range of the heat insulation plate and greatly reducing the deformation amplitude of the heat insulation plate. It can effectively prevent the direct contact between the heat insulation plate and the concave panel, reduce the possibility of the heat insulation plate melting due to high temperature, and help reduce the safety hazards of the electromagnetic cooking device. In addition, the support structure supports the concave panel, which can improve the load-bearing capacity of the concave panel and reduce the possibility of the concave panel cracking due to the frequent movement of the cookware, helping to improve the service life of the concave panel. Secondly, the concave panel includes a first support area, a second support area, and a heat insulation area. The first support area is near the lowest part of the concave panel, and the second support area is on the side of the concave panel close to the first panel. During the operation of the electromagnetic cooking device, a high-frequency alternating magnetic field is formed above the concave panel by the electromagnetic coil disk, and the magnetic field above the first support area and the second support area is relatively weak. Therefore, the heating speed of the parts of the cookware corresponding to the first support area and the second support area is slower. After the heat of the cookware is conducted to the concave panel, the temperatures of the first support area and the second support area on the concave panel are relatively low. When the support structure abuts against the first support area and / or the second support area, the heat conducted from the concave panel to the heat insulation plate through the support structure is reduced, reducing the possibility of the heat insulation plate being damaged by high temperature and helping to extend the service life of the heat insulation plate. In addition, the temperatures of the first support area and the second support area are relatively low, and the heat resistance requirement for the support structure is relatively low, enabling the support structure to be made of cheaper materials, helping to reduce the manufacturing difficulty and cost of the support structure.

[0010] Preferably, the coil includes an inner ring near the lowest part of the electromagnetic coil disc and an outer ring near the highest part of the electromagnetic coil disc. The projection of the inner ring on the concave panel is within the first support area, and the projection of the outer ring on the concave panel is within the second support area. With the foregoing technical solution, at the inner and outer rings of the coil, the winding and sealing of the coil are relatively small, and the magnetic fields generated by the inner and outer rings are relatively weak. Therefore, the temperature rise rate of the part of the cookware directly above the inner and outer rings is slower, and correspondingly, less heat is conducted to the concave panel. The first support area and the second support area are respectively directly above the inner and outer rings, so that the first support area and the second support area can maintain a relatively low temperature, reducing the possibility of the support structure being affected by high temperature. At the same time, it can also reduce the heat conducted to the heat insulation board through the support structure, reducing the possibility of the heat insulation board being damaged due to high temperature.

[0011] Preferably, the support structure includes a first support member corresponding to the first support area and a second support member corresponding to the second support area. The first support member abuts against one side of the first support area close to the heat insulation area, and the second support member abuts against one side of the second support area close to the heat insulation area. With the foregoing technical solution, the distance between the first support member and the second support member can be reduced. Through the cooperation and restriction of the first support member and the second support member, the deformation amplitude of the heat insulation board directly below the heat insulation area can be further reduced, reducing the possibility of direct contact between the heat insulation board and the heat insulation area, effectively avoiding the melting of the heat insulation board due to high temperature, and helping to extend the service life of the heat insulation board.

[0012] Preferably, the support structure is a support column, and the support columns are circumferentially spaced apart. With the foregoing technical solution, the contact area between the support structure and the concave panel can be reduced, thereby reducing the heat conducted by the concave panel through the support structure, helping to reduce the maximum temperature of the heat insulation board during the operation of the electromagnetic cooking device, and reducing the possibility of the heat insulation board being damaged due to high temperature; in addition, using support columns can also reduce the manufacturing cost of the support structure.

[0013] Preferably, the support structure is annularly distributed between the concave panel and the heat insulation board. With the foregoing technical solution, the contact area between the support structure and the concave panel can be increased, improving the support force of the support structure on the concave panel, making the concave panel have a stronger load-bearing capacity, and reducing the possibility of the concave panel cracking; in addition, the annular distribution of the support structure can evenly disperse the heat conducted by the concave panel, avoiding the phenomenon of damage due to excessive local temperature of the heat insulation board.

[0014] Preferably, the support structure is disposed on the upper surface of the heat insulation board, and the top end of the support structure extends upward and abuts against the lower surface of the concave panel. With the foregoing technical solution, the fixation of the support structure on the heat insulation board is relatively simpler and more convenient than on the concave panel, and it can also make the connection between the support structure and the heat insulation board more firm and reliable.

[0015] Preferably, the support structure and the heat insulation plate are of an integral structure. With the above-mentioned technical solution, the connection process between the support structure and the heat insulation plate can be omitted, making the overall assembly process of the electromagnetic cooking device simpler and faster, which helps to improve the assembly efficiency of the electromagnetic cooking device; in addition, the integration of the support structure and the heat insulation plate can improve the strength of the support structure, enabling the support structure to provide stronger and more stable support force for the concave panel, and at the same time, it can also increase the limiting force of the support structure on the heat insulation plate, helping to reduce the deformation range of the heat insulation plate.

[0016] Preferably, the support structure is bonded to the lower surface of the concave panel, and the bottom end of the support structure extends downward and abuts against the upper surface of the heat insulation plate. With the above-mentioned technical solution, the use of the bonding method can simplify the fixed connection between the support structure and the concave panel; in addition, through bonding, the replacement of the support structure can be made simpler and more convenient, without the need to replace the heat insulation plate as a whole, which can greatly reduce the maintenance cost of the electromagnetic cooking device.

[0017] Preferably, the panel assembly further includes a support ring, the support ring wraps the rim of the concave panel, and both sides of the support ring are respectively fixed to the upper surface of the concave panel and the upper surface of the first panel. The support ring supports the cookware to form a gap between the cookware and the concave panel. With the above-mentioned technical solution, the support ring can protect the concave panel, effectively avoiding direct contact between the cookware and the concave panel. During the cooking process, the violent movement of the cookware will not cause a large impact on the concave panel, thereby reducing the possibility of the concave panel cracking and helping to extend the service life of the concave panel; in addition, the support ring can wrap the rim of the concave panel, thereby protecting the rim of the concave panel, reducing the impact force on the rim of the concave panel, and reducing the possibility of the concave panel cracking due to impact; at the same time, both sides of the support ring are respectively fixed to the upper surface of the concave panel and the upper surface of the first panel, which can make the panel assembly more complete in appearance and have higher aesthetics.

[0018] Preferably, the electromagnetic coil disk includes a coil bracket, and a plurality of connection holes are provided at the edge of the coil bracket. The edge of the heat insulation plate is fixed to the edge of the coil bracket through the cooperation of fasteners and the connection holes. With the above-mentioned technical solution, the edge of the heat insulation plate is fixed to the coil bracket through fasteners. The connection position between the heat insulation plate and the coil bracket can cooperate with the support structure to tightly attach the heat insulation plate to the upper surface of the coil bracket as a whole, and at the same time, it can also further reduce the deformation range of the heat insulation plate, reduce the possibility of direct contact between the heat insulation plate and the concave panel, and limit the heat insulation plate in a safe use environment, helping to extend the service life of the heat insulation plate; in addition, the edge of the coil bracket can provide sufficient fixing points, making the connection between the heat insulation plate and the coil bracket simpler and more convenient, and at the same time, the connection between the heat insulation plate and the coil bracket will not affect the coil.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more such features.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As Figures 1 to 5 shown, this embodiment shows an electromagnetic cooking device, which includes a base 1, an upper cover 2, and a panel assembly 3. The upper cover 2 is installed on the base 1. The panel assembly 3 includes a first panel 32 and a concave panel 31. The first panel 32 is provided with mounting holes. The rim of the concave panel 31 is mounted on the first panel 32. The middle part of the concave panel 31 passes through the mounting holes and extends into the base 1. An electromagnetic coil disc 13, a main control board 11, and a cooling fan 12 are provided in the base 1. The overall structure of the electromagnetic coil disc 13 matches that of the concave panel 31, that is, the electromagnetic coil disc 13 is of a concave structure. A heat insulation plate 14 is installed on the side of the electromagnetic coil disc 13 facing the concave panel 31. There is a heat insulation gap 15 between the heat insulation plate 14 and the concave panel 31. After the electromagnetic coil disc 13 is powered on, a heating area is formed on the upper side of the concave panel 31. In addition, the cooling fan 12 is installed on one side of the main control board 11, and a wind shield is installed on the upper side of the cooling fan 12. After the cooling fan 12 is started, the wind shield can converge the airflow formed by the cooling fan 12 and guide the airflow to the main control board 11, thereby improving the heat dissipation effect of the main control board 11.

[0032] As Figures 1 to 3As shown, in this embodiment, there is also a support structure 141 between the heat insulation plate 14 and the concave panel 31. The area of the concave panel 31 facing the heat insulation plate 14 includes a first support area 311 near the lowest side of the concave panel 31, a second support area 312 near the first panel 32, and a heat insulation area 313 located between the first support area 311 and the second support area 312. The support structure 141 is correspondingly arranged for the first support area 311 and the second support area 312, and the heat insulation gap 15 is at least correspondingly arranged for the heat insulation area 313. Of course, it can be understood that in other embodiments, the support structure 141 can also be arranged only corresponding to the first support area 311; or the support structure 141 can also be arranged only corresponding to the second support area 312.

[0033] In this embodiment, there is a support structure 141 between the concave panel 31 and the heat insulation plate 14. The two ends of the support structure 141 respectively abut against the concave panel 31 and the heat insulation plate 14. The support structure 141 exerts extrusion on the heat insulation plate 14, thereby restricting the upward convex range of the heat insulation plate 14 and greatly reducing the deformation amplitude of the heat insulation plate 14. It can effectively prevent the heat insulation plate 14 from coming into direct contact with the concave panel 31, reducing the possibility of the heat insulation plate 14 melting due to high temperature, and helping to reduce the safety hazards of the electromagnetic cooking device; in addition, the support structure 141 supports the concave panel 31, which can improve the load-bearing capacity of the concave panel 31 and reduce the possibility of the concave panel 31 cracking due to the frequent movement of the cookware 4, helping to improve the service life of the concave panel 31; secondly, the concave panel 31 includes a first support area 311, a second support area 312 and a heat insulation area 313, where the first support area 311 is close to the lowest part of the concave panel 31, and the second support area 312 is on the side of the concave panel 31 close to the first panel 32. During the operation of the electromagnetic cooking device, the electromagnetic coil disc 13 forms a high-frequency alternating magnetic field above the concave panel 31, and the magnetic field above the first support area 311 and the second support area 312 is relatively weak. Therefore, the heating speed of the parts of the cookware 4 corresponding to the first support area 311 and the second support area 312 is slower. After the heat of the cookware 4 is conducted to the concave panel 31, the temperatures of the first support area 311 and the second support area 312 on the concave panel 31 are relatively low. When the support structure 141 abuts against the first support area 311 and / or the second support area 312, the heat conducted from the concave panel 31 to the heat insulation plate 14 through the support structure 141 is reduced, reducing the possibility of the heat insulation plate 14 being damaged by high temperature and helping to extend the service life of the heat insulation plate 14; in addition, the temperatures of the first support area 311 and the second support area 312 are relatively low, and the heat resistance requirements for the support structure 141 are relatively low, enabling the support structure 141 to be made of cheaper materials, helping to reduce the manufacturing difficulty and manufacturing cost of the support structure 141.

[0034] As Figure 2 and Figure 3As shown, in this embodiment, the electromagnetic coil disk 13 includes a coil support 132 and a coil 131 wound around the coil support 132. The coil 131 is wound around the center of the coil support 132 and gradually wound towards the edge of the coil support 132. The innermost circle is the one closest to the center of the coil support 132, and the outermost circle is the one closest to the edge of the coil 131. Since the overall structure of the coil support 132 matches the concave panel 31 and has a concave plate structure, the innermost circle closest to the center of the coil support 132 is also the lowest point closest to the coil support 132. Correspondingly, the outermost circle closest to the edge of the coil support 132 is also the highest point closest to the coil support 132. Additionally, since the inner circle and the outer circle are respectively the innermost coil 131 and the outermost coil 131 of the entire coil 131, the winding seal of the coil 131 is smaller at the inner circle and the outer circle of the coil 131, and the magnetic fields generated by the inner circle and the outer circle are relatively weak. Therefore, the temperature rise rate of the pot 4 at the positions directly above the inner circle and the outer circle is slower, and correspondingly, less heat is conducted to the concave panel 31. The coil 131 between the inner circle and the outer circle is wound more densely, and the magnetic field that can be generated is stronger, thereby forming a main heating area on the pot 4. In this embodiment, the projection of the inner circle on the concave panel 31 is within the first support area 311, and the projection of the outer circle on the concave panel 31 is within the second support area 312, that is, the first support area 311 and the second support area 312 are respectively directly above the inner circle and the outer circle, and the heat insulation area 313 is between the first support area 311 and the second support area 312. The first support area 311 and the second support area 312 correspond to the areas of the pot 4 where the temperature rise rate is slower, and the heat insulation area 313 corresponds to the area of the pot 4 where the temperature rise rate is faster. Thereby, the first support area 311 and the second support area 312 can be maintained at a lower temperature, reducing the possibility that the support structure 141 is affected by high temperature, and at the same time, it can also reduce the heat conducted to the heat insulation plate 14 through the support structure 141, reducing the possibility that the heat insulation plate 14 is damaged due to high temperature.

[0035] In addition, in this embodiment, the support structure 141 includes a first support member 1411 corresponding to the first support area 311 and a second support member 1412 corresponding to the second support area 312. The first support member 1411 abuts against one side of the first support area 311 close to the heat insulation area 313, and the second support member 1412 abuts against one side of the second support area 312 close to the heat insulation area 313. Both the first support member 1411 and the second support member 1412 are close to the heat insulation area 313, thereby reducing the distance between the first support member 1411 and the second support member 1412. Both the first support member 1411 and the second support member 1412 will form pressing points on the heat insulation plate 14. When the distance between the two pressing points decreases, the deformation amplitude that the heat insulation plate 14 between the two pressing points can generate will also decrease, thereby effectively avoiding direct contact between the heat insulation plate 14 and the heat insulation area 313 of the concave panel 31 after deformation, reducing the possibility of the heat insulation plate 14 melting due to high temperature, and helping to extend the service life of the heat insulation plate 14.

[0036] In order to make the connection between the heat insulation plate 14 and the coil bracket 132 closer and more firm, in this embodiment, several connection holes are provided at the edge of the coil bracket 132, and through holes matching the connection holes are provided at the edge of the heat insulation plate 14. The edge of the heat insulation plate 14 is fixed to the edge of the coil bracket 132 through the cooperation of fasteners and the connection holes. The fasteners can squeeze the edge of the heat insulation plate 14, and combined with the squeezing of the heat insulation plate 14 by the first support member 1411 and the second support member 1412, the heat insulation plate 14 can be closely attached to the upper surface of the coil bracket 132 as a whole. At the same time, it can also further reduce the deformation amplitude of the heat insulation plate 14, reduce the possibility of direct contact between the heat insulation plate 14 and the concave panel 31, limit the heat insulation plate 14 in a safe use environment, and help to extend the service life of the heat insulation plate 14; in addition, the edge of the coil bracket 132 can provide sufficient fixing points, making the connection between the heat insulation plate 14 and the coil bracket 132 simpler and more convenient, and at the same time, the connection between the heat insulation plate 14 and the coil bracket 132 will not affect the coil 131.

[0037] As Figures 3 to 5As shown, in this embodiment, both the first support member 1411 and the second support member 1412 are support columns, and the support columns are circumferentially spaced and fixed on the upper surface of the heat insulation plate 14. The top ends of the support columns extend vertically upward. When the panel assembly 3 and the upper cover 2 are assembled, the top ends of the support columns abut against the lower surface of the concave panel 31. In addition, in order to keep the top ends of the support columns in contact with the concave panel 31, the top surfaces of the support columns are curved and matched with the lower surface of the concave panel 31, so that the top ends of the support columns can completely fit with the concave panel 31. In this embodiment, using support columns can reduce the contact area between the support structure 141 and the concave panel 31, thereby reducing the heat conducted by the concave panel 31 through the support structure 141, which helps to reduce the maximum temperature of the heat insulation plate 14 during the operation of the electromagnetic cooking device and reduce the possibility of damage to the heat insulation plate 14 due to high temperature. In addition, using support columns can also reduce the manufacturing cost of the support structure 141.

[0038] In order to simplify the connection process between the support structure 141 and the heat insulation plate 14, in this embodiment, the support structure 141 and the heat insulation plate 14 are of an integral structure, so that the connection process between the support structure 141 and the heat insulation plate 14 can be omitted, making the overall assembly process of the electromagnetic cooking device simpler and faster, which helps to improve the assembly efficiency of the electromagnetic cooking device. In addition, the integration of the support structure 141 and the heat insulation plate 14 can improve the strength of the support structure 141, enabling the support structure 141 to provide a stronger and more stable supporting force for the concave panel 31. At the same time, it can also increase the limiting force of the support structure 141 on the heat insulation plate 14, which helps to reduce the deformation amplitude of the heat insulation plate 14. Secondly, when the support structure 141 and the heat insulation plate 14 are of an integral structure, the support structure 141 and the heat insulation plate 14 are made of the same material and have the same heat resistance. Pressing the top end of the support structure 141 against the first support area 311 and the second support area 312 with lower temperatures of the concave panel 31 can prevent the support structure 141 from melting due to the too high temperature it contacts, enabling the support structure 141 to maintain its overall strength and maintain the support for the concave panel 31.

[0039] Of course, it can be understood that in other embodiments, the support structure 141 may also be annularly distributed between the concave panel 31 and the heat insulation plate 14, that is, the first support member 1411 and the second support member 1412 form an annular structure on the heat insulation plate 14. Using the annular structure to abut against the concave panel 31 can increase the contact area between the support structure 141 and the concave panel 31, improve the supporting force of the support structure 141 on the concave panel 31, enable the concave panel 31 to have a stronger bearing capacity, and reduce the possibility of the concave panel 31 cracking. In addition, the annular distribution of the support structure 141 can evenly disperse the heat conducted by the concave panel 31, avoiding the phenomenon of damage to the heat insulation plate 14 due to excessive local temperature.

[0040] Of course, it can be understood that in other embodiments, the support structure 141 can also be directly fixed to the lower surface of the concave panel 31. The bottom end of the support structure 141 extends downward and abuts against the upper surface of the heat insulation plate 14. Since the concave panel 31 is a microcrystalline plate, the support structure 141 can be fixedly connected to the concave panel 31 by bonding. The use of the bonding method can simplify the fixed connection between the support structure 141 and the concave panel 31. In addition, through bonding, the replacement of the support structure 141 can be made simpler and more convenient, without the need to replace the heat insulation plate 14 as a whole, which can greatly reduce the maintenance cost of the electromagnetic cooking device.

[0041] As Figure 2 shown, in this embodiment, the panel assembly 3 further includes a support ring 33. The support ring 33 wraps the rim of the concave panel 31, and both sides of the support ring 33 are respectively fixed to the upper surface of the concave panel 31 and the upper surface of the first panel 32. The support ring 33 supports the cookware 4 so that a gap 41 is formed between the cookware 4 and the concave panel 31. During cooking, users usually perform actions such as tossing the wok and quickly stir-frying ingredients, causing the cookware 4 to move violently. After the support ring 33 supports the cookware 4, it can protect the concave panel 31 and effectively prevent the direct contact between the cookware 4 and the concave panel 31. The violent movement of the cookware 4 during cooking will not cause a large impact on the concave panel 31, thereby reducing the possibility of the concave panel 31 cracking and helping to extend the service life of the concave panel 31. In addition, since the overall strength of the concave panel 31 is weak, the rim of the concave panel 31 is more likely to crack. At the same time, the rim of the concave panel 31 is above the first panel 32 and is extremely vulnerable to impact. The support ring 33 can wrap the rim of the concave panel 31, thereby protecting the rim of the concave panel 31 and reducing the impact force on the rim of the concave panel 31, and reducing the possibility of the concave panel 31 cracking due to impact. At the same time, both sides of the support ring 33 are respectively fixed to the upper surface of the concave panel 31 and the upper surface of the first panel 32, which can make the panel assembly 3 more complete in appearance and have higher aesthetics.

[0042] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
