Description

Technical Field

[0001] The utility model shows a panel component of an electromagnetic heating device and an electromagnetic heating device, belonging to the technical field of electromagnetic heating devices. Background Art

[0002] With the development and promotion of the small household appliance industry, electromagnetic heating devices are deeply loved by consumers because of their advantages such as easy to carry and fast heating. The existing electromagnetic heating devices are provided with a panel assembly, which includes an upper cover, a bracket, a glass panel and a microcrystalline panel, wherein the glass panel is installed on the upper cover, and the glass panel is provided with a mounting hole, the microcrystalline panel is installed on the glass panel and the mounting hole is covered, and the bracket is provided with a gluing area, and the gluing area is filled with glue to bond and fix the glass panel and the microcrystalline panel to the bracket.

[0003] However, during the production process, the upper cover assembly cannot be used immediately after being filled with glue. It is necessary to stack the upper cover assembly on a crimping vehicle for crimping to give full play to the adhesion effect of the glue. However, during the crimping process, pressure needs to be applied to the top of the glass panel and the microcrystalline panel so that the glass panel, the microcrystalline panel and the bracket can fit fully. However, since there is a mounting hole on the glass panel, the glass panel forms a shorter narrow area at the front end and the left and right ends of the mounting hole. The overall strength of the narrow area is weak and the ability to withstand bending is low. During the crimping process, the microcrystalline panel covers the mounting hole and applies pressure to the narrow area. When the applied pressure is too large, the glass panel is prone to deformation or breakage in the narrow area. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that a glass panel is easily deformed or broken in a narrow area. To this end, a panel assembly of an electromagnetic heating device and an electromagnetic heating device are provided. The auxiliary support part can support the second panel, disperse the force exerted on the first panel, and reduce the possibility of deformation or breakage of the first panel.

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

With the above technical solution, the reinforcing rib can effectively improve the overall strength of the first supporting part, thereby improving the supporting capacity of the first supporting part, making the overall structure of the first supporting part more stable, and helping to extend the service life of the first supporting part; in addition, with the support of the reinforcing rib, the first supporting part can form a stable support for the second panel, so that the force of the second panel on the first panel can be kept stable, which helps to reduce the possibility of deformation or rupture of the first panel.

[0014] Preferably, the upper surface of the first supporting portion and / or the step portion is provided with a first gluing area, and the first gluing area is located on the outside of the abutting portion. With the aforementioned technical solution, after the glue in the first gluing area is solidified, the first supporting portion and / or the step portion can also support the second panel through the glue, thereby increasing the contact area between the bracket and the second panel, further sharing the pressure on the first panel, reducing the possibility of deformation or rupture of the first panel, and helping to extend the service life of the first panel; in addition, the abutting portion is located on the inner side of the first gluing area, and the abutting portion abuts against the second panel, which can limit the glue in the first gluing area from flowing along the inner side of the supporting portion into the interior of the electromagnetic heating device, thereby preventing the glue from affecting the normal operation of the electromagnetic heating device.

[0016] Preferably, the upper surface of the auxiliary support portion is provided with a second glue application area for filling glue.

[0035] Embodiment 1:

[0036] like Figures 1 to 9 As shown, this embodiment shows a panel assembly of an electromagnetic heating device, including a first panel 1, a second panel 2, an upper cover 4 for fixing the first panel 1, and a bracket 3 for fixing and installing the first panel 1 and the second panel 2, wherein the first panel 1 is provided with a mounting hole 15, the second panel 2 is covered on the first panel 1 and covers the mounting hole 15, the bracket 3 includes a first supporting portion 31, a second supporting portion 32 and a step portion 33, wherein the step portion 33 is located between the first supporting portion 31 and the second supporting portion 32, the first supporting portion 31 is connected to the upper end of the step portion 33 and is located on the inner side of the step portion 33, The second supporting portion 32 is connected to the lower end of the step portion 33 and is located on the outside of the step portion 33. The step portion 33 and the first supporting portion 31 extend into the mounting hole 15. The first supporting portion 31 is located on the lower side of the second panel 2 and is provided with an abutting portion 311 that abuts against the second panel 2. The second supporting portion 32 extends to the lower side of the first panel 1 and abuts against the first panel 1. The first panel 1 includes a first area 16, and the first area 16 is located at the minimum distance between the side edge of the first panel 1 and the edge of the mounting hole 15. The abutting portion 311 extends inwardly corresponding to the position of the first area 16 to form an auxiliary supporting portion 312 that abuts against the second panel 2.

[0037] In this embodiment, the abutting portion 311 extends inwardly to form an auxiliary supporting portion 312, which abuts against the second panel 2, which can increase the contact area between the abutting portion 311 and the second panel 2, thereby increasing the supporting ability of the first supporting portion 31 to the second panel 2, thereby reducing the pressure on the first panel 1 and reducing the possibility of deformation or rupture of the first panel 1; in addition, the first panel 1 includes a first area 16, and the first area 16 is located at the minimum distance between the side of the first panel 1 and the edge of the mounting hole 15. The strength of the first area 16 is relatively the smallest, the bending resistance is relatively the weakest, and it is most likely to deform or rupture. During the crimping process, the second panel 2 is covered on the edge of the mounting hole 15, and the auxiliary supporting portion 312 is set The auxiliary support portion 312 is arranged at the position of the abutment portion 311 corresponding to the first area 16, and can effectively share the pressure on the first area 16, reduce the force of the second panel 2 on the first area 16, and reduce the possibility of deformation or rupture of the first area 16, so that the edge of the mounting hole 15 remains flat as a whole, which can effectively reduce the assembly gap between the first panel 1 and the second panel 2, and help to reduce the sealing difficulty of the first panel 1 and the second panel 2, so that the panel assembly can maintain good sealing; secondly, by sharing the pressure on the first area 16 through the auxiliary support portion 312, the overall area of ​​the first panel 1 can be reduced as much as possible while keeping the first area 16 intact, which helps to improve the utilization rate of the first panel 1 and the aesthetics of the first panel 1.

[0038] like Figure 1 and Fig. 9As shown, in this embodiment, the first panel 1 is rectangular as a whole, and the first panel 1 has four sides, which are respectively a first side 11, a second side 12, a third side 13 and a fourth side 14, wherein the first side 11 and the second side 12 are arranged oppositely and are both short sides of the first panel 1, the second side 12 and the fourth side 14 are arranged oppositely and are both long sides of the first panel 1, the mounting hole 15 is a circular hole, and the center of the mounting hole 15 does not coincide with the center of the first panel 1, the first panel 1 also includes an operating area 17, the mounting hole 15 and the operating area 17 are respectively close to the first side 11 and the fourth side 14, and since the panel assembly is in use, the panel assembly is usually placed in a position so that the operating area 1 7 is close to the human body, that is, the first side edge 11 is away from the human body, and when the cookware is placed on the second panel 2, the cookware will block the first side edge 11 from entering the human body's field of vision. Therefore, no matter in terms of practicality or aesthetics, the area between the first side edge 11 and the mounting hole 15 does not need to have other designs. The mounting hole 15 is placed as close to the first side edge 11 as possible to form a first area 16 between the first side edge 11 and the mounting hole 15. While maintaining the overall strength of the first panel 1, the utilization rate of the area of ​​the first panel 1 can be effectively improved, the layout design of the first panel 1 can be optimized, and the overall area of ​​the first panel 1 can be reduced, making the panel assembly more compact as a whole, which is helpful to improve the applicability and aesthetics of the first panel 1.

[0039] In addition, Figure 7 and Fig. 9 As shown, in this embodiment, the first panel 1 includes three first areas 16, and the three first areas 16 are respectively located on the outer side of the mounting hole 15 close to the first side 11, the outer side of the mounting hole 15 close to the second side 12, and the outer side of the mounting hole 15 close to the third side 13, that is, the distance from the first side 11 to the center of the mounting hole 15, the distance from the second side 12 to the center of the mounting hole 15, and the distance from the third side 13 to the center of the mounting hole 15 are all kept equal. Correspondingly, the abutment portion 311 in this embodiment is provided with auxiliary support portions 312 at positions corresponding to the three first areas 16, and the auxiliary support portions 312 can share the pressure on the first area 16, thereby reducing the possibility of deformation or rupture of the first panel 1; this design can also reduce the width between the second side 12 and the third side 13 and the mounting hole 15, while maintaining the overall strength of the first panel 1, greatly reducing the area of ​​the first panel 1, which helps to reduce the manufacturing cost of the first panel 1; secondly, this design can make the panel assembly as a whole have a high degree of symmetry, which can improve the aesthetics of the panel assembly.

[0040] It should be noted that, in other embodiments, the distance from the second side 12 to the center of the mounting hole 15 may be greater than the distance from the first side 11 to the center of the mounting hole 15, that is, in this embodiment, the width between the second side 12 and the mounting hole 15 can be widened to enhance the strength and bending resistance of the area between the second side 12 and the mounting hole 15, and the pressure exerted on the area can be resisted by the self-strength of the area, thereby eliminating the auxiliary support portion 312 of the abutment portion 311 in this area; similarly, in other embodiments, the distance from the third side 13 to the center of the mounting hole 15 may be greater than the distance from the first side 11 to the center of the mounting hole 15, that is, in this embodiment, the width between the third side 13 and the mounting hole 15 can be widened to enhance the strength and bending resistance of the area between the third side 13 and the mounting hole 15; of course, it is understandable that in other embodiments, the width between the second side 12 and the mounting hole 15 and the width between the third side 13 and the mounting hole 15 can be widened at the same time.

[0041] Of course, it is understandable that in other embodiments, the first panel 1 may also be circular, elliptical, or other approximately circular structures, and the first area 16 is located outside the mounting hole 15 away from the operating area 17 .

[0042] like Figures 5 to 7 As shown, the auxiliary support portion 312 in this embodiment is a support block formed by extending the abutment portion 311 inwardly. In this embodiment, three support blocks are arranged on the inner side of the abutment portion 311, and the positions of the three support blocks respectively correspond to the three first areas 16 of the first panel 1. The support blocks can correspondingly enhance the supporting capacity of the designated position of the first supporting portion 31, while providing sufficient supporting capacity, it can also reduce the manufacturing cost of the bracket 3.

[0043] It should be noted that, in other embodiments, the number of the support blocks may be increased or decreased according to the number of the first regions 16 in the first panel 1 ; or, the number of the support blocks may be greater than the number of the first regions 16 in the first panel 1 .

[0044] Of course, it is understandable that in other embodiments, the auxiliary support portion 312 may also be a support ring distributed on the inner side of the first supporting portion 31. The support ring can effectively increase the contact area between the first supporting portion 31 and the second panel 2, thereby reducing the length of the support ring extending inward. When it is inconvenient to maintain the overall diameter of the bracket 3, the auxiliary support portion 312 can be kept at a reasonable distance from the electromagnetic wire reel 51, thereby reducing the possibility of the auxiliary support portion 312 being damaged by high temperature, which helps to extend the service life of the auxiliary support portion 312.

[0045] like Figure 6As shown, the upper surface of the auxiliary support part 312 described in this embodiment is provided with a second gluing area 3121 for filling glue. During the assembly process of the panel assembly, the second gluing area 3121 can be filled with glue with a faster curing speed. When the second panel 2 is covered on the mounting hole 15, the glue in the second gluing area 3121 is quickly cured to achieve preliminary bonding between the auxiliary support part 312 and the second panel 2, so that the second panel 2 can be positioned, reducing the possibility of the second panel 2 being offset during the transportation of the panel assembly, helping to maintain the overall aesthetics of the panel assembly and improving the yield of the panel assembly.

[0046] Of course, it is understandable that in other embodiments, the auxiliary support part 312 may also not be provided with the second gluing area 3121. In this embodiment, the upper surface of the auxiliary support part 312 is entirely against the second panel 2, so that the auxiliary support part 312 can effectively increase the contact area between the bracket 3 and the second panel 2, effectively disperse the pressure on the first panel 1, and reduce the possibility of deformation or rupture of the first panel 1.

[0047] like Figures 5 to 8 As shown, the upper surface of the step portion 33 described in this embodiment is provided with a first gluing area 331 for filling glue, and the first gluing area 331 is between the second panel 2 and the step portion 33, and the first gluing area 331 is distributed in a ring shape with the step portion 33, and the first gluing area 331 is on the outside of the abutting portion 311. During the assembly process of the panel assembly, the first gluing area 331 is first filled with glue, and then the first panel 1 is placed on the second supporting portion 32, and the step portion 33 and the first supporting portion 31 are extended into the mounting hole 15, and then the second panel 2 is covered on the mounting hole 15. After crimping, the glue can fill the entire first gluing area 331, and when the glue in the first gluing area 331 is cured, the step portion 33 can also support the second panel 2 through the glue, thereby increasing the contact area between the bracket 3 and the second panel 2, further sharing the pressure on the first panel 1, reducing the possibility of deformation or rupture of the first panel 1, and helping to extend the service life of the first panel 1.

[0048] Of course, it is understandable that in other embodiments, the first gluing area 331 may also be provided on the upper surface of the first supporting portion 31 , the first gluing area 331 is located between the first supporting portion 31 and the second panel 2 , and the first gluing area 331 is located on the outside of the abutting portion 311 .

[0049] like Figure 2 and Figure 3As shown, the abutment portion 311 in this embodiment is located on the inner side of the first gluing area 331. During the assembly process of the panel assembly, after the second panel 2 is covered, the second panel 2 abuts against the abutment portion 311. After the second panel 2 squeezes the glue in the first gluing area 331, the abutment portion 311 will form a barrier to the glue, so that the glue in the first gluing area 331 overflows to the outside of the first supporting portion 31, thereby limiting the glue in the first gluing area 331 from flowing along the inner side of the supporting portion into the interior of the electromagnetic heating device, thereby preventing the glue from affecting the normal operation of the electromagnetic heating device. In addition, through the abutment portion 3 11 is restricted, so that more glue overflows to the outside of the first supporting part 31, so that the glue can overflow to the inner wall of the mounting hole 15. When the overflowing glue is bonded to the inner wall of the mounting hole 15, the connection stability between the bracket 3 and the first panel 1 can be improved. At the same time, when the glue overflows to the inner wall of the mounting hole 15, the glue is bonded to the inner wall of the mounting hole 15, the bottom wall of the second panel 2 and the step portion 33 respectively. At this time, the glue can also form a seal for the gap between the first panel 1 and the second panel 2, thereby preventing water or dirt from entering the bracket 3 through the gap, which is beneficial to maintaining the cleanliness of the bracket 3.

[0050] like Figure 3 As shown, in the present embodiment, an overflow glue area 37 is provided between the step portion 33 and the inner wall of the mounting hole 15, and the overflow glue area 37 is connected to the first gluing area 331. During the assembly process of the panel assembly, excess glue in the first gluing area 331 will be squeezed into the overflow glue area 37. The overflow glue area 37 can provide overflow glue space for excess glue. During the gluing process, more glue can be filled into the first gluing area 331 so that the glue can fully fill the gluing area after assembly, thereby fully ensuring the filling effect of the gluing area and reducing the phenomenon of insufficient glue. In addition, the overflow glue area 37 is located between the outer side of the step portion 33 and the inner wall of the mounting hole 15, which can increase the glue between the step portion 33 and the first panel 1, improve the bonding effect between the step portion 33 and the first panel 1, and thereby enhance the connection stability between the first panel 1 and the bracket 3, making the overall structure of the panel assembly more stable and reliable, and at the same time, it can also improve the sealing between the first panel 1 and the second panel 2, which helps to improve the service life of the electromagnetic heating device.

[0051] like Figure 6As shown, in this embodiment, a plurality of positioning ribs 35 are provided on the outer circumference of the step portion 33, and the positioning ribs 35 are evenly spaced along the circumference of the step portion 33. The overflow area 37 is located between two adjacent positioning ribs 35. When the step portion 33 extends into the mounting hole 15, the positioning ribs 35 abut against the inner wall of the mounting hole 15. The step portion 33 can be positioned by the positioning ribs 35 so that the step portion 33 is centered in the mounting hole 15. At the same time, the contact panel of the second supporting portion 32 with the first panel 1 can be kept uniform, thereby ensuring that the supporting capacity of the second supporting portion 32 on the edge of the mounting hole 15 is kept as balanced as possible. This reduces the possibility of deformation or cracking of the first panel 1 at the edge of the mounting hole 15, helping to extend the service life of the panel assembly. In addition, by positioning the step portion 33 through the positioning ribs 35, the spacing between the step portion 33 and the inner wall of the mounting hole 15 can be kept uniform, that is, the overall width of the overflow glue area 37 can be kept uniform. When the glue in the first gluing area 331 overflows into the overflow glue area 37, the glue can also be evenly distributed between the step portion 33 and the inner wall of the mounting hole 15, so that the overall adhesion of the step portion 33 to the first panel 1 is more uniform and reliable, which is beneficial to improving the connection stability between the step portion 33 and the first panel 1.

[0052] In order to allow the step portion 33 to smoothly extend into the mounting hole 15, the top end of the positioning rib 35 described in this embodiment is provided with a guide surface for guiding the step portion 33 to extend into the mounting hole 15. The guide surface is an inclined surface arranged at an angle, and the bottom end of the guide surface extends toward the outside of the step portion 33. The guide surface can reduce the difficulty of the step portion 33 extending into the mounting hole 15, thereby improving the assembly efficiency of the bracket 3 and reducing the possibility of the positioning rib 35 and the mounting hole 15 being stuck. Of course, it can be understood that in other embodiments, the guide surface can also be a smooth curved surface.

[0053] It should be noted that in other embodiments, a positioning ring may also be provided on the side of the step portion 33 facing the inner wall of the mounting hole 15. After the step portion 33 extends into the mounting hole 15, the positioning ring as a whole abuts against the inner wall of the mounting hole 15, thereby positioning the step portion 33, and the overflow glue area 37 is located on the upper side of the positioning ring.

[0054] like Figure 3 and Figure 8 As shown, in this embodiment, a reinforcing rib 36 is provided at the connection between the lower side of the first supporting portion 31 and the step portion 33. The reinforcing rib 36 can effectively improve the overall strength of the first supporting portion 31, thereby improving the supporting capacity of the first supporting portion 31, making the overall structure of the first supporting portion 31 more stable, and helping to extend the service life of the first supporting portion 31; in addition, with the support of the reinforcing rib 36, the first supporting portion 31 can form a stable support for the second panel 2, so that the force of the second panel 2 on the first panel 1 can remain stable, which helps to reduce the possibility of deformation or rupture of the first panel 1.

[0055] like Figure 2 and Figure 4 As shown, in this embodiment, a first support column 34 is provided on the lower side of the bracket 3, and the panel assembly also includes an upper cover 4, which is fixed to the lower edge of the first panel 1, and a third gluing area 41 for filling glue is provided on the upper surface of the upper cover 4, and the third gluing area 41 is located between the upper cover 4 and the first panel 1. The glue in the third gluing area 41 can improve the connection stability between the upper cover 4 and the first panel 1, and a second support column 42 is provided on the lower side of the upper cover 4, and the bottom end surface of the second support column 42 is lower than the bottom end surface of the first support column 34.

[0056] like Figure 4 As shown, when the panel assembly is assembled, the panel assembly needs to be crimped to give full play to the adhesion effect of the glue. During the crimping process, several panel assemblies can be stacked, wherein the first support column 34 is located in the projection of the second panel 2 on the plane where the first panel 1 is located, and the second support column 42 is located on the lower side of the first panel 1. Therefore, when several panel assemblies are stacked on each other, the first support column 34 is pressed on the second panel 2 of the lower panel assembly, and the second support column 42 is pressed on the first panel 1 of the lower panel assembly.

[0057] In addition, in this embodiment, the first support column 34 is located at the connection between the step portion 33 and the second supporting portion 32. The overall thickness of the step portion 33 is relatively large. The first support column 34 is connected to the step portion 33. The step portion 33 can increase the strength of the first support column 34, so that the bracket 3 as a whole has a stronger bearing capacity, which helps to improve the overall stability of the panel assembly; in addition, the second supporting portion 32 is used to support the first panel 1. The first support column 34 is connected to the second supporting portion 32, which can increase the bearing capacity of the second supporting portion 32, provide stable support for the first panel 1, and help reduce the possibility of deformation of the first panel 1.

[0058] Of course, it is understandable that in other embodiments, the first support column 34 may be located at the lower side of the step portion 33 or at the lower side of the second supporting portion 32 .

[0059] Embodiment 2:

[0060] The main difference between this embodiment and embodiment 1 is that the operation area in this embodiment is not located in the first panel, the center of the first panel coincides with the center of the mounting hole, and the first panel includes at least two first areas, wherein the two first areas are symmetrically distributed on both sides of the mounting hole, thereby further reducing the area of ​​the first panel and reducing the production cost of the first panel.

[0061] In this embodiment, the first panel can be a rectangle, and a first area is formed between the mounting hole and the two long sides of the rectangle respectively. The corresponding auxiliary support portion is arranged at a position corresponding to the abutment portion and the long side. The width between the two short sides of the rectangle and the mounting hole is large, and has higher strength and bending resistance.

[0062] Of course, it is understandable that in this embodiment, the first panel may also be square, and the first area is formed between the mounting hole and the four sides of the first panel, and the corresponding auxiliary support portion is arranged at a position corresponding to the abutment portion and the side of the first panel.

[0063] In addition, in this embodiment, the first panel can also be circular, and the first panel and the mounting hole are concentric circles. In this case, the entire first panel is the first area; secondly, in this embodiment, the first panel can also be elliptical, and the mounting hole and the two ends of the short axis respectively form the first area.

[0064] Embodiment three:

[0065] like Fig.10 As shown, this embodiment shows an electromagnetic heating device, including a shell, the shell includes a base 5 and a panel assembly, the panel assembly adopts the panel assembly as described in Example 1 or Example 2, the base 5 is provided with an electromagnetic wire reel 51, a fan 52, a control assembly 53, an operating assembly 54 and a power cord 55, wherein the electromagnetic wire reel 51 is located on the inner side of the bracket 3, that is, on the lower side of the second panel 2, and the electromagnetic wire reel 51 forms a heating area on the second panel 2 after heating, and the cookware can be placed on the second panel 2 for cooking, and the operating assembly 54 is located on the lower side of the operating area 17, and the user triggers the operating assembly 54 by pressing the operating area 17, thereby controlling and adjusting the electromagnetic heating device.
