Description

[Technical field]

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an electromagnetic cooking utensil. [Background technology]

[0002] The electromagnetic cooking utensils in the prior art have the advantages of fast heating, no open flame, safety and convenience, etc., and are favored and recognized by more and more consumers. Take the electromagnetic cooker as an example. The electromagnetic cooker includes a shell and a panel installed on the shell and used to support the pot. The shell is provided with an electromagnetic wire coil, and the electromagnetic wire coil generates an alternating magnetic field when working to heat the pot. In order to prevent the pot from sliding off the panel, the existing shell is provided with a stopper in the area located on the outer peripheral side of the panel. The stopper is higher than the panel to limit the pot. In order to prevent the high-temperature pot from scalding the stopper, the existing stopper sleeve is provided with a scalding protection cap. However, since the outer side of the side wall of the scalding protection cap close to the pot is in contact with the high-temperature pot, the contact area is large. Therefore, when the temperature of the pot is high, the heat of the pot can still be transferred to the stopper through the scalding protection cap. In addition, the stopper is a plastic part and is not resistant to high temperature. Therefore, the structural design of the existing scalding protection cap will not be able to effectively insulate and there is a risk of scalding the stopper. [Contents of the utility model]

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an electromagnetic cooking utensil, which can reduce the contact area between the scalding protection cap and the pot and / or the panel, so as to reduce the risk of the stopper being scalded.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An electromagnetic cooking utensil comprises a shell and a panel mounted on the shell and used to support a cooker, wherein the shell is provided with a stopper in an area located on the outer peripheral side of the panel, wherein the stopper is higher than the panel so as to limit the position of the cooker, wherein the stopper is provided with a scalding prevention cap, wherein the scalding prevention cap comprises a first side wall arranged close to the panel, wherein a side surface of the first side wall close to the panel is a concave-convex surface, and a first heat-insulating gap is formed between the concave surface of the concave-convex surface and the panel and / or the cooker.

[0006] In the above-mentioned electromagnetic cooking device, the first side wall is a wavy pleated wall, which includes alternately arranged concave parts and convex parts, wherein the concave parts are close to one side of the panel to form a concave surface of the concave-convex surface, and the convex parts are close to one side of the panel to form a convex surface of the concave-convex surface.

[0007] In the above electromagnetic cooking appliance, a limiting rib is protrudingly provided on a side of the stopper close to the panel, and the limiting rib supports a side of the recess away from the panel.

[0008] In the above-mentioned electromagnetic cooking appliance, a relief area corresponding to the convex portion is provided on one side of the stop member close to the panel, and the convex portion and the relief area are arranged at intervals so as to form a second heat insulation gap between the convex portion and the relief area.

[0009] In the above-mentioned electromagnetic cooking appliance, both the concave portion and the convex portion extend along the height direction of the first side wall; or the concave portion and the convex portion are alternately arranged along the height direction of the first side wall.

[0010] In the above-mentioned electromagnetic cooking appliance, a thinning groove is provided on one side surface of the first side wall close to the panel, and the side wall of the thinning groove forms the concave surface.

[0011] In the above-mentioned electromagnetic cooking appliance, the bottom of the first side wall is located between the stop member and the panel, and the convex surface is arranged at an interval from the panel so as to form a third heat insulation gap between the convex surface and the panel.

[0012] In the above-mentioned electromagnetic cooking appliance, the heat insulation cap further includes a mounting rib provided at the bottom of the first side wall and extending in a direction away from the stop member, and the housing includes a support surface for supporting the panel, and the mounting rib is clamped and fixed between the panel and the support surface.

[0013] In the above-mentioned electromagnetic cooking appliance, a mounting groove is provided on the support surface and is recessed downward, the mounting rib is embedded in the mounting groove, and the thickness of the mounting rib is not greater than the depth of the mounting groove.

[0014] In the above-mentioned electromagnetic cooking appliance, the heat insulation cap is adhesively fixed to the stop member.

[0015] Advantages of the present utility model:

[0016] 1. The heat insulation cap in the present utility model includes a first side wall disposed close to the panel. One side surface of the first side wall close to the panel is a concave-convex surface, and a first heat insulation gap is formed between the concave surface of the concave-convex surface and the panel and / or the cookware. With such a design, when the cookware and / or the panel come into contact with the first side wall, the convex surface of the concave-convex surface will come into contact with the cookware and / or the panel, while the concave surface of the concave-convex surface will not come into contact with the cookware and / or the panel. Thus, the temperature of the concave surface is relatively low, and the effect of reducing the contact area between the first side wall and the panel and / or the cookware is achieved, so as to reduce the heat directly transferred from the high-temperature cookware and the panel to the first side wall, and further reduce the heat transferred from the first side wall to the stop member. In addition, by using the first heat insulation gap existing between the concave surface and the panel and / or the cookware, when the first heat insulation gap communicates with the outside, the heat of the high-temperature cookware and the panel can also be dissipated through the first heat insulation gap, so as to further reduce the heat transferred to the first side wall, and further reduce the risk of the stop member being melted by heat.

[0017] 2. The first side wall is a wavy pleated wall, and the pleated wall includes alternately arranged concave parts and convex parts. The concave part is close to the side of the panel to form a concave surface of the concave-convex surface, and the convex part is close to the side of the panel to form a convex surface of the concave-convex surface. With such a design, when the side of the stopper close to the panel is a plane, even if the concave part contacts the stopper, the convex part and the stopper can be kept out of contact, thereby reducing the heat transferred from the convex part to the stopper, and further reducing the risk of scalding the stopper; in addition, the arrangement of the pleated wall can also enhance the structural strength of the first side wall, and prevent the first side wall from deforming and causing the concave-convex surface to disappear.

[0018] 3. A limiting rib is convexly provided on the side of the stopper close to the panel, and the limiting rib supports the side of the recess away from the panel. With this design, the recess can be isolated from the stopper by the support of the limiting rib to the recess, so as to increase the heat transfer path, thereby increasing the loss in the heat transfer process, reducing the heat transferred from the recess to the stopper, and thus reducing the risk of scalding the stopper; in addition, the design of the limiting rib also enhances the structural strength of the stopper and reduces the risk of scalding.

[0019] 4. The side of the stopper close to the panel has an escape zone corresponding to the convex part, and the convex part and the escape zone are arranged at intervals to form a second thermal insulation gap between the convex part and the escape zone. Such a design can not only avoid the convex part from contacting the escape zone, but also transfer the heat of the convex part to the second thermal insulation gap for heat dissipation, thereby reducing the heat transferred from the convex part to the stopper and preventing the stopper from being scalded.

[0020] 5. The concave portion and the convex portion both extend along the height direction of the first side wall; or the concave portion and the convex portion are alternately arranged along the height direction of the first side wall. Such a design can reduce the processing difficulty of the first side wall and also improve the appearance of the anti-scalding cap.

[0021] 6. The bottom of the first side wall is located between the stopper and the panel, and the convex surface is spaced from the panel so as to form a third thermal insulation gap between the convex surface and the panel. This design can avoid contact between the first side wall and the panel, and when the panel is in a high temperature state, the heat transferred from the high temperature panel to the first side wall can be reduced, thereby reducing the heat transferred from the first side wall to the stopper, thereby reducing the risk of scalding of the stopper.

[0022] 7. The anti-scalding cap further includes a mounting rib disposed at the bottom of the first side wall and extending in a direction away from the stopper, the housing includes a support surface for supporting the panel, and the mounting rib is clamped and fixed between the panel and the support surface. With such a design, the anti-scalding cap can be fixed by clamping the mounting rib between the panel and the support surface to prevent the anti-scalding cap from falling off, and the anti-scalding cap does not need to be fixed to the stopper by bonding.

[0023] 8. The supporting surface is provided with a downwardly concave mounting groove, and the mounting rib is embedded in the mounting groove. The thickness of the mounting rib is not greater than the depth of the mounting groove. With such a design, not only can the anti-scalding cap be better positioned and fixed, but also the influence of the mounting rib on the stability of the panel lapped on the supporting surface can be avoided.

[0024] 9. The anti-scalding cap is adhesively fixed to the stopper. With such a design, it can not only fix the anti-scalding cap to prevent it from falling off, but also eliminate the mounting rib, avoiding the contact between the mounting rib and the part of the housing supporting the panel, so that the heat of the cookware and the panel cannot be transferred to the part of the housing supporting the panel through the anti-scalding cap, thereby reducing the risk of the part of the housing supporting the panel being melted.

[0025] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and drawings.

Specific implementation manners

[0039] The present utility model provides an electromagnetic cooking appliance, including a housing and a panel mounted on the housing and used for supporting a cooking pot. A stop member is provided in a region of the housing on the outer peripheral side of the panel. The stop member is higher than the panel to limit the cooking pot. The stop member is sleeved with a heat insulation cap. The heat insulation cap includes a first side wall disposed close to the panel. One side surface of the first side wall close to the panel is a concave-convex surface. A first heat insulation gap is formed between the concave surface of the concave-convex surface and the panel and / or the cooking pot. With such a design, when the cooking pot and / or the panel contact the first side wall, the convex surface of the concave-convex surface will contact the cooking pot and / or the panel, while the concave surface of the concave-convex surface will not contact the cooking pot and / or the panel. Thus, the temperature of the concave surface is relatively low, and the effect of reducing the contact area between the first side wall and the panel and / or the cooking pot is achieved, so as to reduce the heat directly transferred from the high-temperature cooking pot and the panel to the first side wall, and further reduce the heat transferred from the first side wall to the stop member. In addition, by using the first heat insulation gap existing between the concave surface and the panel and / or the cooking pot, when the first heat insulation gap communicates with the outside, the heat of the high-temperature cooking pot and the panel can also be dissipated through the first heat insulation gap, so as to further reduce the heat transferred to the first side wall, and further reduce the risk of the stop member being melted by heat.

[0041] Embodiment 1

[0042] As Figures 1 to 8 shown, in this embodiment, the electromagnetic cooking appliance includes a housing 100 and a panel 200. The housing 100 includes a base and an upper cover 110. The base and the upper cover 110 enclose a cooking cavity. An electromagnetic coil disc is installed in the cooking cavity. The upper cover 110 is provided with an installation opening 1101 corresponding to the electromagnetic coil disc. The panel 200 is installed on the upper cover 110 to cover the installation opening 1101. A cookware (not shown in the figure) can be placed on the panel 200. When the electromagnetic coil disc works, it generates an alternating magnetic field to heat the cookware. Wherein, a stop member 120 is provided in the area of the upper cover 110 on the outer peripheral side of the panel 200. The top surface of the stop member 120 is higher than the side surface of the panel 200 facing away from the base, so that the stop member 120 limits the cookware to prevent the cookware from slipping off the panel 200. The existing stop member 120 is sleeved with a heat insulation cap 300. The heat insulation cap 300 includes a first side wall 310 close to the panel 200. The top surface of the first side wall 310 is higher than the top surface of the panel 200, and the bottom surface of the first side wall 310 is lower than the top surface of the panel 200, that is, the bottom of the first side wall 310 is located between the stop member 120 and the panel 200, so that the first side wall 310 separates the stop member 120 and the panel 200. Wherein, one side surface of the first side wall 310 close to the panel 200 is an uneven surface. Designed in this way, when the first side wall 310 comes into contact with the outer peripheral side of the panel 200, and when the cookware is offset and comes into contact with the first side wall 310, the convex surface of the uneven surface will come into contact with the cookware and the panel 200, while the concave surface of the uneven surface will not come into contact with the cookware and the panel 200. The temperature of the concave surface is relatively low, so as to achieve the effect of reducing the contact area between the first side wall 310 and the panel 200 and the cookware, thereby reducing the heat directly transferred from the high-temperature cookware and the panel 200 to the first side wall 310, and thus reducing the heat transferred from the first side wall 310 to the stop member 120; In addition, a first heat insulation gap 400 can be formed between the concave surface and the panel 200 and the cookware. When the first heat insulation gap 400 communicates with the outside, the heat of the high-temperature cookware and the panel 200 can also be dissipated through the first heat insulation gap 400, so as to further reduce the heat transferred to the first side wall 310, and further reduce the risk of the stop member 120 being melted by heat.

[0043] Specifically, the anti-scalding cap 300 in this embodiment includes a side wall disposed around the stopper 120 and a top wall 320 connected to the top of the side wall. When the anti-scalding cap 300 is sleeved on the stopper 120, the top wall 320 covers the top surface of the stopper 120. The stopper 120 is a hollow structure integrally formed with the upper cover 110. The stopper 120 has a first side surface 121 disposed close to the panel 200. The portion of the side wall corresponding to the first side surface 121 forms a first side wall 310. The first side wall 310 is a corrugated folded wall. The folded wall includes alternately arranged concave portions 311 and convex portions 312. One side surface of the concave portion 311 close to the panel 200 forms a concave surface of the concave-convex surface, and one side surface of the convex portion 312 close to the panel 200 forms a convex surface of the concave-convex surface. With such a design, when the first side surface 121 is a plane, even if the concave portion 311 comes into contact with the first side surface 121, the convex portion 312 can be made not to contact the first side surface 121. Since the convex portion 312 has more heat, such a design can effectively reduce the heat transferred from the convex portion 312 to the stopper 120, thereby further reducing the risk of the stopper 120 being melted by heat; in addition, the setting of the folded wall can also enhance the structural strength of the first side wall 310 and prevent the first side wall 310 from deforming and causing the concave-convex surface to disappear.

[0044] In order to further reduce the heat transferred from the concave portion 311 to the stopper 120, a plurality of limiting ribs 122 protrude from the first side surface 121 in this embodiment. The limiting ribs 122 extend along the height direction of the first side surface 121. The limiting ribs 122 support the side of the concave portion 311 facing away from the panel 200. The contact area between the limiting ribs 122 and the concave portion 311 is smaller than the area of the side of the concave portion 311 facing away from the panel 200. With such a design, the support of the concave portion 311 by the limiting ribs 122 can isolate the concave portion 311 from the stopper 120 to increase the heat transfer path, thereby increasing the loss during the heat transfer process, achieving the reduction of the heat transferred from the concave portion 311 to the stopper 120, and further reducing the risk of the stopper 120 being melted by heat; in addition, the setting of the limiting ribs 122 also enhances the structural strength of the stopper 120 to reduce the risk of the stopper 120 being melted by heat.

[0045] The area of the first side surface 121 where the limiting ribs 122 are not provided forms an avoidance area 123 corresponding to the convex portion 312. The convex portion 312 and the avoidance area 123 are spaced apart to form a second heat insulation gap 500 between the convex portion 312 and the avoidance area 123. With such a design, not only can the contact between the convex portion 312 and the avoidance area 123 be avoided, but also the distance of the second heat insulation gap 500 can be increased, so that the heat of the convex portion 312 is transferred into the second heat insulation gap 500 for effective heat dissipation, thereby reducing the heat transferred from the convex portion 312 to the stopper 120 and preventing the stopper 120 from being melted by heat.

[0046] Preferably, in this embodiment, both the concave portion 311 and the convex portion 312 extend along the height direction of the first side wall 310, so that the upper end of the first heat insulation gap 400 communicates with the outside air. With such a design, the heat in the first heat insulation gap 400 can be dissipated in time, so as to further reduce the heat of the first side wall 310, and further reduce the heat transferred from the first side wall 310 to the stopper 120, preventing the stopper 120 from being melted by heat. In addition, with such a design, the extending directions of the concave portion 311 and the convex portion 312 are the same as the demolding direction during the manufacturing of the heat insulation cap 300, which can reduce the processing difficulty of the first side wall 310 and improve the appearance of the heat insulation cap 300 at the same time.

[0047] To improve the installation reliability of the heat insulation cap 300, the heat insulation cap 300 in this embodiment further includes an installation rib 330. The installation rib 330 is provided at the bottom of the first side wall 310 and is integrally formed with the first side wall 310. The installation rib 330 extends from the bottom of the first side wall 310 in a direction away from the stopper 120. The upper cover 110 includes a support surface 111 for supporting the panel 200. The support surface 111 surrounds the outside of the installation opening 1101. The panel 200 is lapped on the support surface 111 and is adhesively fixed to the support surface 111, and the installation rib 330 is clamped and fixed between the panel 200 and the support surface 111. With such a design, the heat insulation cap 300 can be fixed by clamping the installation rib 330 between the panel 200 and the support surface 111, so as to prevent the heat insulation cap 300 from falling off, and there is no need to adhesively fix the heat insulation cap 300 to the stopper 120.

[0048] Preferably, the support surface 111 is provided with a downwardly concave installation groove 1110. The installation rib 330 is embedded in the installation groove 1110, and the thickness of the installation rib 330 is not greater than the depth of the installation groove 1110. With such a design, not only can the heat insulation cap 300 be better limited and fixed, but also the influence of the installation rib 330 on the stability of the panel 200 lapping on the support surface 111 can be avoided.

[0049] Finally, to reduce the heat transferred from the cookware to the stopper 120, the stopper 120 in this embodiment is arc-shaped, and a plurality of stoppers 120 are spaced outside the panel 200, so as to reduce the total contact area of all the heat insulation caps 300 with the cookware and the panel 200, and further reduce the heat transferred from the high-temperature cookware and the panel 200 to the stopper 120 through the heat insulation caps 300, so as to further reduce the risk of the stopper 120 being melted by heat. In addition, it can also reduce the material cost of the stopper 120 and the heat insulation cap 300, so as to reduce the manufacturing cost of the product.

[0050] It can be understood that in other embodiments of the present utility model, the concave portions and the convex portions may also be alternately arranged along the height direction of the first side wall, that is, the first heat insulation gap extends along the circumferential direction of the panel, and both ends of the first heat insulation gap communicate with the outside, so as to further improve the heat dissipation speed in the first heat insulation gap.

[0051] It can be understood that in other embodiments of the present utility model, a plurality of convex bumps distributed in a matrix protrude from the side of the first side wall close to the panel, a groove is formed between two adjacent convex bumps, the surface of the convex bump forms a convex surface, and the surface of the groove forms a concave surface.

[0052] It can be understood that in other embodiments of the present utility model, a thinning groove is provided on the side surface of the first side wall close to the panel, and the side wall of the thinning groove forms a concave surface.

[0053] It can be understood that in other embodiments of the present utility model, the bottom surface of the first side wall is higher than the top surface of the panel. When the cookware is offset and contacts the first side wall, only a first heat insulation gap is formed between the concave surface of the concave-convex surface and the cookware.

[0054] It can be understood that in other embodiments of the present utility model, when the cookware is not offset and does not contact the first side wall, only a first heat insulation gap is formed between the concave surface of the concave-convex surface and the cookware.

[0055] It can be understood that in other embodiments of the present utility model, when the bottom of the first side wall is located between the stopper and the panel, the convex surface is spaced from the panel, so as to form a third heat insulation gap between the convex surface and the panel. With such a design, it is possible to prevent the first side wall from contacting the panel. When the panel is in a high-temperature state, the heat transferred from the high-temperature panel to the first side wall can be reduced, so as to reduce the heat transferred from the first side wall to the stopper, thereby reducing the risk of the stopper being melted by heat.

[0056] Embodiment Two

[0057] As Figure 9 and 10 shown, compared with Embodiment One, the difference in this embodiment is that the heat insulation cap 300 is adhesively fixed on the stopper 120, that is, a caulking groove 124 for accommodating glue is provided on the top surface of the stopper 120, and the top wall 320 of the heat insulation cap 300 is adhesively fixed to the stopper 120 through the glue. With such a design, it can not only fix the heat insulation cap 300 to prevent the heat insulation cap 300 from falling off, but also eliminate the installation ribs in Embodiment One, avoid the installation ribs from contacting the supporting surface, so that the heat of the cookware and the panel cannot be transferred to the supporting surface through the heat insulation cap, thereby reducing the risk of the supporting surface being melted by heat.

[0058] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
