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 to carry 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 the concave panel partially 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 strength of the ceramic glass panel with a curved concave structure is weak, it is easy to crack during use, and then the electromagnetic coil disk is directly exposed to the outside. In order to prevent users from accidentally touching the exposed electromagnetic coil disk and being scalded, the existing electromagnetic cooking devices usually install a heat insulation plate above the electromagnetic coil disk. However, there is still a large gap between the first panel and the electromagnetic coil disk, resulting in that the user's finger can be inserted into the interior of the base along the gap and touch the live components in the base, thus having a large potential safety hazard. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that after the concave panel cracks, it is easy for users to touch the live components through the gap between the first panel and the electromagnetic coil disk. For this reason, an electromagnetic cooking device is provided to reduce the gap between the first panel and the electromagnetic coil disk and reduce the potential safety hazard.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An electromagnetic cooking device includes a base and a panel assembly. An electromagnetic coil disk is arranged in the base, and a heat insulation plate is installed above the electromagnetic coil disk. The panel assembly includes a first panel and a concave panel. The first panel is provided with a mounting hole for the concave panel to extend into. The edge of the electromagnetic coil disk is located below the first panel and has a gap with the first panel. A retaining rib is arranged between the electromagnetic coil disk and the panel assembly. The retaining rib at least partially extends into the gap and blocks part of the gap, and a heat dissipation channel is formed between the retaining rib and the heat insulation plate or the first panel.

[0007] The beneficial effects of adopting the utility model are:

[0008] In the present utility model, there is a retaining rib between the electromagnetic coil plates. Part of the retaining rib is located in the gap and blocks part of the gap, thereby reducing the height of the gap. The retaining rib can play an effective blocking role, thereby reducing the possibility that the user's finger directly passes through the gap and extends into the interior of the base, avoiding direct contact between the user's finger and the live electrical components inside the base, effectively reducing the safety hazards of the electromagnetic cooking device, and making the use of the electromagnetic cooking device safer and more reliable. In addition, only part of the gap is blocked by the retaining rib, and a heat dissipation channel is formed between the retaining rib and the heat insulation plate or the first panel. During the use of the electromagnetic cooking device, the high-frequency alternating magnetic field generated by the coil acts on the bottom of the cookware, and eddy currents are generated on the bottom of the cookware to generate heat. Part of the heat generated by the cookware converges between the concave panel and the electromagnetic coil plate. The heat dissipation channels are distributed on the outer edge of the electromagnetic coil plate, and the heat between the concave panel and the electromagnetic coil plate can be dissipated to the outer periphery of the electromagnetic coil plate through the heat dissipation channels, which helps to reduce the temperature rise rate between the concave panel and the electromagnetic coil plate, thereby reducing the possibility of the coil being affected by high temperature and effectively extending the service life of the coil.

[0009] Preferably, the bottom end of the retaining rib is fixed to the edge of the heat insulation plate, and the top end of the retaining rib extends towards the first panel. With the foregoing technical solution, the retaining rib is formed on the heat insulation plate, which can reduce the manufacturing difficulty of the retaining rib, and at the same time can also keep the overall structure of the panel assembly and the electromagnetic coil plate simple, and can effectively avoid the retaining rib affecting the assembly difficulty of the panel assembly and the electromagnetic coil plate.

[0010] Preferably, an anti-radiation ring is provided around the outer periphery of the heat insulation plate, and a plurality of positioning card slots are provided at the edge of the heat insulation plate. The anti-radiation ring is positioned on the outer periphery of the retaining rib through the positioning card slots. With the foregoing technical solution, the anti-radiation ring can effectively reduce the leakage of magnetic lines of force, so that the magnetic lines of force can converge above the electromagnetic coil plate, which helps to improve the heating efficiency of the electromagnetic coil plate for the cookware, and at the same time can also reduce the impact of the electromagnetic on the user, further improving the safety of using the electromagnetic cooking device. In addition, an induced current will also be generated in the anti-radiation ring under the action of the coil. By positioning the anti-radiation ring on the outer periphery of the retaining rib, the retaining rib can also block the anti-radiation ring, avoiding the user from having direct contact with the anti-radiation ring and causing an electric shock phenomenon, and effectively reducing the installation hidden danger of the electromagnetic cooking device.

[0011] Preferably, the electromagnetic coil plate includes a coil bracket, and the bottom end of the retaining rib is fixed to the coil bracket, and the top end of the retaining rib extends towards the first panel. With the foregoing technical solution, the retaining rib is fixed on the coil bracket, and then the retaining rib surrounds the outer periphery of the heat insulation plate. At this time, the retaining rib can also position the heat insulation plate, effectively reducing the installation difficulty between the heat insulation plate and the coil bracket.

[0012] Preferably, the top end of the rib is fixed to the lower side of the concave panel, and the bottom end of the rib extends towards the heat insulation plate. With the foregoing technical solution, the heat dissipation channel is located on the upper surface of the heat insulation plate, and the heat generated by the cookware converges between the heat insulation plate and the concave panel, making it easier for the heat to be dissipated to the outside of the electromagnetic coil disk along the heat dissipation channel, which helps to improve the heat dissipation efficiency and further reduce the possibility of the coil being affected by high temperature.

[0013] Preferably, the top end of the rib abuts against the lower side of the first panel, and the bottom end of the rib extends towards the heat insulation plate. With the foregoing technical solution, the rib is located on the lower side of the first panel, and the heat dissipation channel is formed between the bottom of the rib and the heat insulation plate. The heat dissipation channel is closer to the coil bracket and deeper into the base, which can increase the possibility of the user's finger touching the heat dissipation channel, thereby preventing the user's finger from reaching deep into the base and directly contacting the live components.

[0014] Preferably, the panel assembly further includes an upper cover for installing the first panel. The upper cover is provided with a support plate for supporting the first panel, and the rib is fixed to the inner side of the support plate. With the foregoing technical solution, the support plate of the upper cover extends to the upper side of the coil bracket, which can effectively increase the contact area between the upper cover and the first panel, disperse the pressure received by the upper cover, help to improve the supporting ability of the upper cover for the first panel, and make the fixation between the first panel and the upper cover more firm and reliable.

[0015] Preferably, the rib is integrally annular, and the diameter of the rib is larger than the diameter of the mounting hole. With the foregoing technical solution, the diameter of the rib is larger than the diameter of the mounting hole, that is, the rib is located on the lower side of the first panel, and the corresponding heat dissipation channel is also on the lower side of the first panel. Thus, it can prevent the heat dissipation channel from being directly exposed below the mounting hole, increase the difficulty of the user's finger contacting the heat dissipation channel, and further reduce the possibility of the user's finger passing through the heat dissipation channel and contacting the live components, making the use of the electromagnetic cooking device safer and more reliable.

[0016] Preferably, the rib includes a plurality of convex ribs, which are distributed at intervals and enclose an annular shape. The distance between adjacent two convex ribs is less than the height of the heat dissipation channel. With the foregoing technical solution, a heat dissipation gap is formed between adjacent two convex ribs, and the width of the heat dissipation gap is less than the height of the heat dissipation channel. Thus, it can prevent the user's finger from passing through the heat dissipation gap, and the heat between the concave panel and the heat insulation plate can be dissipated to the outside of the coil bracket through the heat dissipation gap, which can further improve the heat dissipation effect.

[0017] Preferably, the height of the heat dissipation channel is H, and 0 mm < H ≤ 8 mm. With the foregoing technical solution, while restricting the user's finger from passing through the heat dissipation channel, it can also enable the heat dissipation channel to have a good heat dissipation effect; when H > 8 mm, the height of the heat dissipation channel is relatively large, enabling the user's finger to pass through the heat dissipation channel, which may cause the user to touch the live electrical components inside the base, posing a great potential safety hazard to the use of the electromagnetic cooking device; when H = 0 mm, that is, the blocking rib completely closes the gap between the first panel and the coil bracket, thereby restricting the heat generated by the cookware between the concave panel and the coil bracket, accelerating the temperature rise rate between the concave panel and the coil bracket. When the temperature is too high, it may affect the coil, easily causing the coil to heat up too quickly and reducing the service life of the coil.

[0032] Embodiment 1:

[0033] As Figures 1 to 6As shown in the figure, this embodiment discloses an electromagnetic cooking device, which includes a base 1 and a panel assembly 2. The panel assembly 2 includes a first panel 21, a concave panel 22 and an upper cover 11. The upper cover 11 is installed on the base 1. A support plate for supporting the first panel 21 is formed at the top of the upper cover 11. The first panel 21 is fixedly connected to the upper cover 11. An installation hole 211 is provided on the first panel 21. The middle part of the concave panel 22 passes through the installation hole 211 and extends into the base 1. The maximum diameter of the concave panel 22 is larger than the installation hole 211, thereby restricting the concave panel 22 from completely falling into the installation hole 211. The panel assembly 2 further includes a steel ring 23. One side of the steel ring 23 is fixed on the first panel 21, and the other side crosses the top edge of the concave panel 22 and is fixed on the inner side of the concave panel 22. The steel ring 23 can fix the first panel 21 and the concave panel 22, reducing the possibility of relative shaking between the first panel 21 and the concave panel 22, making the assembly of the first panel 21 and the concave panel 22 more stable and reliable. In addition, the steel ring 23 can also block the top edge of the concave panel 22, which helps to improve the aesthetic appearance of the panel assembly 2. Secondly, the concave panel 22 is a ceramic glass panel. When the ceramic glass panel is in a curved concave plate structure, its overall strength is relatively weak, especially the top edge of the concave panel 22. By blocking the top edge of the concave panel 22 with the steel ring 23, the possibility of the top edge of the concave panel 22 being damaged by impact can be reduced, which helps to improve the service life of the concave panel 22.

[0034] In addition, in this embodiment, an electromagnetic induction coil disc 3, a cooling fan 51 and a main control board 52 are provided in the base 1. The electromagnetic induction coil disc 3 is fixed on the lower side of the concave panel 22. The electromagnetic induction coil disc 3 includes a coil bracket 31 and a coil 32. The coil 32 is wound around the coil bracket 31, and the structure of the coil bracket 31 matches that of the concave panel 22, which is also a curved concave plate structure. In order to prevent users from directly contacting the coil 32 and getting scalded, a heat insulation plate 4 is installed on the coil bracket 31, and the heat insulation plate 4 is attached to the upper surface of the coil bracket 31. In addition, a wind shield 53 is installed on the upper side of the cooling fan 51. The wind shield 53 can converge the airflow formed by the cooling fan 51 and direct the airflow to the main control board 52, which can improve the heat dissipation effect of the main control board 52.

[0035] As Figure 2As shown, in this embodiment, the edge of the electromagnetic coil disc 3 is located below the first panel 21, that is, the diameter of the coil bracket 31 is greater than the diameter of the mounting hole 211, and there is a gap 6 between the coil bracket 31 and the first panel 21. A retaining rib 41 is provided between the electromagnetic coil disc 3 and the panel assembly 2. The retaining rib 41 at least partially extends into the gap 6 and blocks part of the gap 6. A heat dissipation channel 61 is formed between the retaining rib 41 and the heat insulation plate 4 or the first panel 21. The retaining rib 41 can thereby reduce the height of the gap 6. The retaining rib 41 can play an effective blocking role. When the concave panel 22 is broken, the gap 6 will be exposed in the mounting hole 211, and the user's finger can directly contact the gap 6 through the mounting hole 211. By restricting the height of the gap 6 through the retaining rib 41, the possibility that the user's finger directly passes through the gap 6 and extends into the base 1 can be reduced, avoiding direct contact between the user's finger and the live electrical components in the base 1, effectively reducing the safety hazards of the electromagnetic cooking device, and making the use of the electromagnetic cooking device safer and more reliable. Additionally, the retaining rib 41 only blocks part of the gap 6, and a heat dissipation channel 61 is formed between the retaining rib 41 and the heat insulation plate 4 or the first panel 21. During the use of the electromagnetic cooking device, the high-frequency alternating magnetic field generated by the coil 32 acts on the bottom of the cookware, and eddy currents are generated on the bottom of the cookware to generate heat. Part of the heat generated by the cookware converges between the concave panel 22 and the electromagnetic coil disc 3. The heat dissipation channels 61 are distributed on the outer edge of the electromagnetic coil disc 3, and the heat between the concave panel 22 and the electromagnetic coil disc 3 can be dissipated to the outer peripheral side of the electromagnetic coil disc 3 through the heat dissipation channels 61, which helps to reduce the heating rate between the concave panel 22 and the electromagnetic coil disc 3, and thereby can reduce the possibility of the coil 32 being affected by high temperature, and can effectively extend the service life of the coil 32.

[0036] As Figure 3 and Figure 4 shown, in this embodiment, the bottom end of the retaining rib 41 is fixed to the heat insulation plate 4. The retaining rib 41 is annularly distributed on the edge of the heat insulation plate 4. The top end of the retaining rib 41 extends towards the first panel 21, and the retaining rib 41 and the heat insulation plate 4 are of an integral structure. The heat dissipation channel 61 is formed between the top end of the retaining rib 41 and the first panel 21. The integrated design of the retaining rib 41 and the heat insulation plate 4 can reduce the manufacturing difficulty and cost of the retaining rib 41. At the same time, the fixing between the retaining rib 41 and the heat insulation plate 4 can also be omitted. When the heat insulation plate 4 is fixed to the coil bracket 31, the fixing of the retaining rib 41 is completed, which can significantly improve the assembly efficiency of the electromagnetic cooking device. Additionally, the retaining rib 41 is fixed to the heat insulation plate 4, so that no additional structure needs to be provided on the coil bracket 31 and the panel assembly 2 to fix the retaining rib 41, which can keep the overall structure of the panel assembly 2 and the electromagnetic coil disc 3 simple, and can effectively avoid the retaining rib 41 affecting the assembly difficulty of the panel assembly 2 and the electromagnetic coil disc 3.

[0037] In addition, in this embodiment, the diameter of the retaining rib 41 is greater than the diameter of the mounting hole 211, that is, the retaining rib 41 is located on the lower side of the first panel 21. Correspondingly, the heat dissipation channel 61 is also located on the lower side of the first panel 21. Thus, it can be avoided that the heat dissipation channel 61 is directly exposed below the mounting hole 211, increasing the difficulty for the user's finger to contact the heat dissipation channel 61, and further reducing the possibility that the user's finger passes through the heat dissipation channel 61 and touches the live components, making the use of the electromagnetic cooking device safer and more reliable.

[0038] Of course, it can be understood that in other embodiments, the retaining rib 41 and the heat insulation plate 4 may also be of a split structure, and the retaining rib 41 and the heat insulation plate 4 can be fixed by a clamping structure or a fastener.

[0039] As Figure 3 shown, in this embodiment, the height of the heat dissipation channel 61 is H, that is, the distance between the top end surface of the retaining rib 41 and the bottom end surface of the first panel 21 is H, and 0 mm < H ≤ 8 mm. With the above design, while restricting the user's finger from passing through the heat dissipation channel 61, it can also ensure that the heat dissipation channel has a good heat dissipation effect. When H > 8 mm, the height of the heat dissipation channel 61 is relatively large. After the concave panel 22 is broken, the heat dissipation channel 61 will be directly exposed in the mounting hole 211 of the first panel 21, and the user's finger can directly contact the heat dissipation channel 61 through the mounting hole 211. When the heat dissipation channel 61 is too large, the user's finger can pass through the heat dissipation channel 61, resulting in the user possibly touching the live components inside the base 1, posing a great potential safety hazard to the use of the electromagnetic cooking device. When H = 0 mm, that is, the retaining rib 41 completely closes the gap 6 between the first panel 21 and the coil support 31, which will limit the heat generated by the cookware between the concave panel 22 and the coil support 31, accelerating the temperature rise rate between the concave panel 22 and the coil support 31. When the temperature is too high, it may affect the coil 32, easily causing the coil 32 to heat up too fast and reducing the service life of the coil 32.

[0040] As Figures 3 to 5As shown in the figure, in this embodiment, a plurality of lugs 42 are arranged at intervals on the outer peripheral side of the heat insulation plate 4. The lugs 42 extend radially outward along the heat insulation plate 4. A card seat 43 is provided on the lug 42, and a positioning card slot 431 is formed on the card seat 43. An anti-radiation ring 45 is arranged around the outer peripheral side of the heat insulation plate 4. The anti-radiation ring 45 is positioned on the outer peripheral side of the rib 41 through the positioning card slot 431, and the diameter of the anti-radiation ring 45 is larger than the maximum diameter of the coil 32. During the use of the electromagnetic cooking device, the coil 32 will generate a high-frequency alternating magnetic field, and the anti-radiation ring 45 can reduce the magnetic field lines diverging from the coil 32 to the outside of the coil bracket 31, thereby effectively reducing the leakage of magnetic field lines, enabling the magnetic field lines to converge above the electromagnetic coil disc 3, which helps to improve the heating efficiency of the electromagnetic coil disc 3 for the cookware, and at the same time can also reduce the electromagnetic impact on the user, further improving the use safety of the electromagnetic cooking device.

[0041] In addition, the anti-radiation ring 45 is an aluminum ring. When the high-frequency alternating magnetic field generated by the coil 32 acts on the anti-radiation ring 45, an induced current will also be generated in the anti-radiation ring 45. And positioning the anti-radiation ring 45 on the outer peripheral side of the rib 41, the rib 41 can also form an obstruction to the anti-radiation ring 45, preventing the user from having direct contact with the anti-radiation ring 45 and causing an electric shock phenomenon, and can effectively reduce the installation hidden danger of the electromagnetic cooking device.

[0042] Of course, it can be understood that in other embodiments, the rib 41 can also be fixed on the coil bracket 31. The retaining ring is annularly distributed on the edge of the coil bracket 31. The top end of the rib 41 extends towards the first panel 21. The heat dissipation channel 61 is formed between the top surface of the rib 41 and the first panel 21. The heat insulation plate 4 is located inside the rib 41, and the rib 41 surrounds the outer peripheral side of the heat insulation plate 4. At this time, the rib 41 can also position the heat insulation plate 4, effectively reducing the installation difficulty between the heat insulation plate 4 and the coil bracket 31; in addition, in order to prevent the user from directly contacting the anti-radiation ring 45, in this embodiment, the rib 41 can also be provided with a relief hole for the lug 42 to pass through. After the heat insulation plate 4 is fixed on the coil bracket 31, the lug 42 passes through the rib 41 from the relief hole, so that the entire card seat 43 is located outside the rib 41, enabling the anti-radiation ring 45 to be positioned on the outer peripheral side of the rib 41; of course, it can be understood that the card seat 43 can also be directly fixed on the outer peripheral side of the rib 41.

[0043] Of course, it can be understood that in other embodiments, the rib 41 can also be fixed to the lower side of the concave panel 22. The bottom end of the rib 41 extends towards the heat insulation plate 4, and the heat dissipation channel 61 is located on the upper surface of the heat insulation plate 4. The heat generated by the cookware converges between the heat insulation plate 4 and the concave panel 22, making it easier for the heat to be dissipated along the heat dissipation channel 61 to the outside of the electromagnetic coil disk 3, which helps to improve the heat dissipation efficiency and further reduce the possibility of the coil 32 being affected by high temperature. In addition, it should be noted that in order to prevent the concave panel 22 from cracking outside the rib 41 and causing the user's finger to reach into the interior of the base 1 between the rib 41 and the mounting hole 211, the distance between the rib 41 and the mounting hole 211 in this embodiment is d, and 0 mm < d ≤ 8 mm. Reducing the distance between the rib 41 and the mounting hole 211 can prevent the user's finger from directly reaching into the base 1 between the rib 41 and the mounting hole 211. Of course, it can be understood that the bottom end of the rib 41 can also extend towards the lower side of the first panel 21, so that the bottom end of the rib 41 extends below the first panel 21, that is, the rib 41 is generally conical in shape.

[0044] Of course, it can be understood that in other embodiments, the rib 41 can also be directly fixed to the lower side of the first panel 21 by adhesive. The bottom end of the rib 41 extends towards the heat insulation plate 4. The rib 41 is located on the lower side of the first panel 21, and the heat dissipation channel 61 is formed between the bottom of the rib 41 and the heat insulation plate 4. The heat dissipation channel 61 is closer to the coil bracket 31 and deeper into the base 1, which can increase the possibility of the user's finger coming into contact with the heat dissipation channel 61, and thus prevent the user's finger from reaching into the interior of the base 1 and coming into direct contact with the live electrical components.

[0045] In addition, the rib 41 can also be fixed to the inner side of the support plate. In order to enable the rib 41 to effectively block the gap 6, the support plate can extend inwards until the edge of the support plate is on the upper side of the coil bracket 31. The top end of the rib 41 is fixed to the support plate, and the bottom end of the rib 41 extends downwards. The support plate extending to the upper side of the coil bracket 31 can effectively increase the contact panel between the upper cover 11 and the first panel 21, disperse the pressure received by the upper cover 11, help to improve the supporting ability of the upper cover 11 for the first panel 21, and make the fixation between the first panel 21 and the upper cover 11 more firm and reliable.

[0046] Embodiment 2:

[0047] Such as Figure 7As shown in the figure, the main difference between this embodiment and the first embodiment is that in this embodiment, the rib 41 includes a plurality of convex ribs, which are distributed at intervals and enclose a ring shape. A heat dissipation gap 44 is formed between adjacent two convex ribs. The width of the heat dissipation gap 44 is h, and the width of the heat dissipation gap 44 is less than the height of the heat dissipation channel 61. A heat dissipation gap 44 is formed between adjacent two convex ribs, and the width of the heat dissipation gap 44 is less than the height of the heat dissipation channel 61. Thus, it can prevent the user's finger from passing through the heat dissipation gap 44, and the heat between the concave panel 22 and the heat insulation plate 4 can be dissipated to the outside of the coil bracket 31 through the heat dissipation gap 44, which can further improve the heat dissipation effect.

[0048] It should be noted that the rib 41 in this embodiment can also be arranged on the coil bracket 31 or on the lower side of the first panel 21 or on the lower side of the concave panel 22.

[0049] The other structures of this embodiment are the same as those of the first embodiment, and will not be elaborated here one by one.

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.
