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] In the prior art, the bracket usually includes an outer supporting part for supporting the glass panel, and the upper surface of the outer supporting part is concave to form a gluing area, and the gluing area is located at the lower side of the glass panel. During the assembly process of the panel assembly, the gluing area is first filled with glue, and then the glass panel cover is installed on the outer supporting part, and the glue in the gluing area is squeezed. The glue in the gluing area will overflow and flow into between the outer supporting part and the glass panel, which will cause a gap between the outer supporting part and the glass panel, affecting the assembly tightness of the outer supporting part and the glass panel. In addition, the overflow of the glue makes it impossible for the outer supporting part to fit tightly with the glass panel, reducing the contact area between the outer supporting part and the glass panel, thereby making the external force on the outer supporting part more concentrated, causing the outer supporting part to be easily deformed or broken, and reducing the service life of the outer supporting part. Secondly, opening the gluing area on the outer supporting part will also reduce the strength of the outer supporting part itself, reduce the bearing capacity of the outer supporting part, and easily cause deformation or breakage during the crimping process. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the outer supporting part of the existing bracket is prone to deformation or breakage. For this purpose, a panel assembly of an electromagnetic heating device and an electromagnetic heating device are provided.

[0014] Preferably, the second panel cover is mounted on the first panel, the inner supporting portion extends into the mounting hole, a glue overflow area is formed between the step portion and the inner wall of the mounting hole, and the glue overflow area is connected to the second gluing area.

[0031] Embodiment 1:

[0032] like Figures 1 to 4 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 11, the second panel 2 is covered on the first panel 1 and covers the mounting hole 11, the bracket 3 includes an inner supporting portion 31, an outer supporting portion 32 and a step portion 33, wherein the step portion 33 is between the inner supporting portion 31 and the outer supporting portion 32, and the inner supporting portion 31 is connected to the outer supporting portion 32. The upper end of the step portion 33 is located on the inner side of the step portion 33, the outer supporting portion 32 is connected to the lower end of the step portion 33 and is located on the outer side of the step portion 33, the step portion 33 and the inner supporting portion 31 extend into the mounting hole 11, the inner supporting portion 31 is located on the lower side of the second panel 2, and is provided with an abutting portion 311 abutting against the second panel 2, the outer supporting portion 32 extends to the lower side of the first panel 1 and abuts against the first panel 1, and a first gluing area 322 for filling with glue is formed between the outer side wall 321 of the outer supporting portion 32 and the bottom surface of the first panel 1.

[0033] In this embodiment, the first gluing area 322 is arranged between the outer side wall 321 of the outer supporting part 32 and the bottom surface of the first panel 1. During the assembly process of the panel assembly, after the bracket 3 and the first panel 1 are assembled, the first gluing area 322 is filled with glue. Therefore, the assembly of the first panel 1 and the bracket 3 will not squeeze the glue in the first gluing area 322, thereby avoiding the overflow of the glue in the first gluing area 322, reducing the amount of glue entering between the first panel 1 and the outer supporting part 32, making the assembly of the outer supporting part 32 and the first panel 1 tighter, which helps to improve the stability of the overall structure of the panel assembly, and also allows the outer supporting part 32 to maintain a larger contact panel with the first panel 1, dividing the panel The external force exerted on the outer supporting part 32 is dispersed, the possibility of deformation or fracture of the outer supporting part 32 is reduced, and the service life of the outer supporting part 32 is extended. In addition, the provision of the first gluing area 322 can save the need for grooving on the outer supporting part 32, and can maintain the overall integrity of the outer supporting part 32, which helps to improve the overall strength of the outer supporting part 32, enhance the bearing capacity of the outer supporting part, and reduce the possibility of deformation or fracture of the outer supporting part 32. Secondly, after the first gluing area 322 is filled with glue, the glue can seal the assembly gap between the outer supporting part 32 and the first panel 1, thereby preventing water or dirt from entering the interior of the electromagnetic heating device through the assembly gap, and helps to improve the sealing of the panel assembly.

[0034] like Figure 2 and Figure 3As shown, the outer side wall 321 of the outer supporting portion 32 described in the present embodiment includes a first wall surface 3211 and a second wall surface 3212, wherein the upper end of the second wall surface 3212 abuts against the first panel 1, the lower end of the second wall surface 3212 is connected to the upper end of the first wall surface 3211, and the lower end of the first wall surface 3211 extends toward the inner side of the outer supporting portion 32 and is connected to the bottom wall of the outer supporting portion 32. In the present embodiment, the outer side wall 321 includes a discontinuous first wall surface 3211 and a discontinuous second wall surface 3212, which can increase the area of ​​the outer side wall 321, thereby increasing the adhesion area of ​​the glue, helping to improve the bonding effect of the glue in the first gluing area 322, and improving the connection stability between the outer supporting portion 32 and the first panel 1.

[0035] It should be noted that, in the present embodiment, the first wall 3211 is a conical surface as a whole, and the second wall 3212 is a vertically distributed cylinder. The diameter of the first wall 3211 gradually decreases from top to bottom. While keeping the thickness of the outer support portion 32 unchanged, the area of ​​the outer wall 321 can be effectively increased, thereby increasing the adhesion area of ​​the glue, improving the bonding effect of the glue on the outer support portion 32, and making the bonding between the outer support portion 32 and the first panel 1 more firm and reliable, which helps to improve the connection stability of the panel assembly; in addition, the lower end of the first wall 3211 extends toward the inner side of the outer support portion 32, so that the first glue area 322 is completely exposed on the lower side of the first panel 1, avoiding the outer support portion 32 from blocking the first glue area 322, which can effectively reduce the difficulty of filling the glue, and help to improve the assembly efficiency of the panel assembly.

[0036] It should also be noted that during the assembly of the panel assembly, the inner supporting portion 31 and the step portion 33 are first extended into the mounting hole 11 of the first panel 1. After the bracket 3 and the first panel 1 are positioned, glue is filled into the first gluing area 322 through a glue gun. When the first wall surface 3211 is a conical surface as a whole, the outer wall 321 of the outer supporting portion 32 can be matched with the muzzle of the glue gun to keep the glue gun and the outer wall 321 of the outer supporting portion 32 in contact. In the process of the glue gun filling the first gluing area 322 with glue, the glue can be kept in close contact with the outer wall 321, thereby reducing the gap between the glue and the outer wall 321, improving the adhesion effect of the glue, and making the connection between the outer supporting portion 32 and the first panel 1 more firm and reliable.

[0037] Of course, it is understandable that in other embodiments, the second wall 3212 can also be a conical surface, and the slope of the first wall 3211 is different from the slope of the second wall 3212, and the lower end of the second wall 3212 also extends to the inner side of the outer support portion 32, thereby avoiding the second wall 3212 from blocking the first gluing area 322; or, while the second wall 3212 is a conical surface, the slope of the second wall 3212 can also be the same as the slope of the first wall 3211, that is, the outer wall 321 of the outer support portion 32 can be a complete and continuous conical surface.

[0038] In addition, in other embodiments, the first wall surface 3211 can be a concave curved surface, or it can also be a convex curved surface. The concave or convex curved surface can further increase the area of ​​the outer wall 321, thereby increasing the adhesion area of ​​the glue, which helps to improve the bonding effect of the glue in the first gluing area 322.

[0039] like Figure 4 As shown, the inner supporting portion 31 in this embodiment is provided with an abutting portion 311 abutting against the second panel 2, and the upper surface of the step portion 33 is provided with a second gluing area 331 for filling with glue, the second gluing area 331 is between the second panel 2 and the step portion 33, and the second gluing area 331 is annularly distributed on the outer peripheral side of the abutting portion 311. During the assembly process of the panel assembly, the second gluing area 331 is first filled with glue, and then the first panel 1 is placed on the outer supporting portion 32, and the step portion 33 and the inner supporting portion 31 are extended into the mounting hole 11. , and then the second panel 2 is covered on the mounting hole 11. After crimping, the glue can fill the entire second gluing area 331. When the glue in the second gluing area 331 is cured, the inner supporting portion 31 and the second panel 2 can be bonded by the glue in the second gluing area 331, thereby achieving relative fixation of the first panel 1 and the second panel 2, and avoiding direct bonding of the first panel 1 and the second panel 2 by the glue. While maintaining the cleanliness of the first panel 1 and the second panel 2, a stable connection between the first panel 1 and the second panel 2 can also be achieved.

[0040] It should be noted that, in the present embodiment, the diameter of the second panel 2 is larger than the diameter of the mounting hole 11. When the panel assembly is assembled, the second panel 2 covers the mounting hole 11, and the second panel 2 protrudes as a whole from the top surface of the first panel 1. Since the heating component of the electromagnetic heating device is located at the lower side of the second panel 2, the heating component forms a heating area on the second panel 2. The second panel 2 protrudes from the first panel 1 to serve as a reminder, which can guide the user to place the cookware in the heating area, making the placement of the cookware more accurate and helping to improve the heating efficiency. In addition, the second panel 2 can be used to support the cookware, which can avoid contact between the first panel 1 and the cookware, thereby allowing the first panel 1 to use a lower-priced glass panel, while the second panel 2 uses a high-temperature resistant microcrystalline panel, thereby reducing the manufacturing cost of the product.

[0041] Of course, it is understandable that in other embodiments, the diameter of the second panel 2 may also be smaller than the diameter of the step portion 33 mounting hole 11. In the overall structure of the bracket 3, the inner supporting portion 31 and the outer supporting portion 32 maintain the same height, the step portion 33 is located between the inner supporting portion 31 and the outer supporting portion 32 and protrudes from the inner supporting portion 31 and the outer supporting portion 32, and the diameter of the step portion 33 is larger than the diameter of the second panel 2. During the assembly process of the panel assembly, the step portion 33 extends into the mounting hole 11, and the second panel 2 is installed on the inner side of the step portion 33. A second gluing area 331 is formed between the inner wall of the mounting hole 11, the outer peripheral side of the second panel 2 and the step portion 33.

[0042] Of course, it is understandable that in other embodiments, the second gluing area 331 can also be arranged on the upper surface of the inner supporting portion 31, the second gluing area 331 is between the second panel 2 and the step portion 33, and the second gluing area 331 is annularly distributed on the outer peripheral side of the abutting portion 311. During the assembly process of the panel assembly, after the second panel 2 is covered, the second panel 2 abuts against the abutting portion 311. After the second panel 2 squeezes the glue in the second gluing area 331, the abutting portion 311 will form a barrier to the glue, so that the glue in the second gluing area 331 overflows to the outside of the inner supporting portion 31, thereby limiting the glue in the second gluing area 331 from flowing along the inner side of the supporting portion to the electromagnetic heating device. The inside of the mounting hole 11 is provided to prevent the glue from affecting the normal operation of the electromagnetic heating device; in addition, through the restriction of the abutment portion 311, more glue is allowed to overflow to the outside of the inner supporting portion 31, so that the glue can overflow to the inner wall of the mounting hole 11. When the overflowing glue is bonded to the inner wall of the mounting hole 11, 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 11, the glue is bonded to the inner wall of the mounting hole 11, 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.

[0043] like Figure 3 As shown, in the present embodiment, a glue overflow area 34 is provided between the step portion 33 and the inner wall of the mounting hole 11, and the glue overflow area 34 is connected to the second glue area 331. During the assembly process of the panel assembly, the excess glue in the second glue area 331 will be squeezed into the glue overflow area 34. The glue overflow area 34 can provide an overflow space for the excess glue. During the gluing process, more glue can be filled into the second glue area 331 so that the glue can fully fill the second glue area 331 after assembly, thereby fully ensuring the filling effect of the glue area and reducing the phenomenon of insufficient glue. In addition, the glue overflow area 34 is located between the outer side of the step portion 33 and the inner wall of the mounting hole 11, 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.

[0044] In order to allow the glue in the second glue application area 331 to overflow, the step portion 33 in this embodiment is provided with a bending portion, which transitions from one side of the inner supporting portion 31 to one side of the outer supporting portion 32 in an arc shape. The bending portion can make the glue overflow more smoothly, and can also guide the glue to overflow to the overflow glue area 34, which can effectively reduce the overflow of the glue to between the inner supporting portion 31 and the second panel 2, thereby allowing the inner supporting portion 31 and the second panel 2 to maintain a close fit; in addition, the bending portion can also make the overflow of the glue more uniform, and the glue can be evenly distributed in the overflow glue area 34, so that the bonding strength between the step portion 33 and the first panel 1 is as consistent as possible. Of course, it can be understood that in other embodiments, the bending portion can also be an inclined transition from one side of the inner supporting portion 31 to one side of the outer supporting portion 32.

[0045] In this embodiment, a plurality of positioning ribs 35 are provided on the outer circumference of the step portion 33. The positioning ribs 35 are evenly spaced along the circumference of the step portion 33. The glue overflow area 34 is located between two adjacent positioning ribs 35. When the step portion 33 is extended into the mounting hole 11, the positioning ribs 35 abut against the inner wall of the mounting hole 11. The step portion 33 can be positioned by the positioning ribs 35 so that the step portion 33 is centered in the mounting hole 11. At the same time, the contact area between the outer supporting portion 32 and the first panel 1 can be kept uniform, thereby ensuring that the supporting capacity of the outer supporting portion 32 on the edge of the mounting hole 11 is kept as balanced as possible, thereby reducing The possibility of the first panel 1 being deformed or broken at the edge of the mounting hole 11 is reduced, which helps to extend the service life of the panel assembly; in addition, the step portion 33 is positioned by the positioning ribs 35, so that the spacing between the step portion 33 and the inner wall of the mounting hole 11 can be kept uniform, that is, the overall width of the overflow area 34 is kept uniform, and when the glue in the first gluing area 322 overflows into the overflow area 34, the glue can also be evenly distributed between the step portion 33 and the inner wall of the mounting hole 11, 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.

[0046] In order to allow the step portion 33 to smoothly extend into the mounting hole 11, 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 11. 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 11, thereby improving the assembly efficiency of the bracket 3 and reducing the possibility of the positioning rib 35 and the mounting hole 11 being stuck. Of course, it can be understood that in other embodiments, the guide surface can also be a smooth curved surface.

[0047] 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 11. After the step portion 33 extends into the mounting hole 11, the positioning ring as a whole abuts against the inner wall of the mounting hole 11, thereby positioning the step portion 33, and the overflow glue area 34 is located on the upper side of the positioning ring.

[0048] In order to improve the supporting capacity of the inner supporting portion 31, a reinforcing rib 36 is provided at the connection between the lower side of the inner supporting portion 31 and the step portion 33 in the present embodiment. The reinforcing rib 36 can effectively improve the overall strength of the inner supporting portion 31, thereby improving the supporting capacity of the inner supporting portion 31, making the overall structure of the inner supporting portion 31 more stable, and helping to extend the service life of the inner supporting portion 31; in addition, the inner supporting portion 31 forms a stable support for the second panel 2, which can keep the force of the second panel 2 on the first panel 1 stable, and help to reduce the possibility of deformation or rupture of the first panel 1.

[0049] like Figure 1 and Figure 2 As shown, the panel assembly in this embodiment also includes an upper cover 4, which is fixed to the lower edge of the first panel 1. The upper surface of the upper cover 4 is provided with a third gluing area 41 for filling with glue, and the third gluing area 41 is located between the upper cover 4 and the first panel 1. During the assembly process of the panel assembly, after the first panel 1, the second panel 2 and the bracket 3 are assembled, the glue is filled in the third gluing area 41, and the assembled first panel 1 is covered on the upper side of the upper cover 4, so that the first panel 1 squeezes the glue in the third gluing area 41. When the glue in the third gluing area 41 is solidified, the assembly of the panel assembly is completed.

[0050] Embodiment 2:

[0051] like Figure 5 As shown, the main difference between this embodiment and embodiment 1 is that the outer side wall 321 of the outer supporting portion 32 described in this embodiment has a step surface 3213, the lower end of the step surface 3213 extends to the bottom wall of the outer supporting portion 32, the upper end of the step surface 3213 has an extension portion 323, and the first gluing area 322 extends to the step surface 3213. After the first gluing area 322 is filled with glue, the glue can wrap the extension portion 323, so that the entire extension portion 323 is between the glue and the first panel 1. When the glue is solidified, the glue can support the outer supporting portion 32, so that the connection between the outer supporting portion 32 and the first panel 1 is more firm and reliable.
