[0002] Cooking appliances with control panels, such as induction cookers and infrared cookers, previously used one-piece structures, such as tempered glass. However, this material is expensive and cannot be molded into complex shapes. Therefore, composite control panel structures are now used, which have openings in the main body of the control panel and ceramic bodies placed in the openings. The pots are placed on the ceramic bodies for heating.

[0003] During the ceramic body processing, a protective coating, such as glazing, is applied to the upper and peripheral sides of the ceramic body to form a glazed surface. The glazed surface includes a top glaze section and a peripheral glaze section. The top glaze section is located on the upper side of the ceramic body, and the peripheral glaze section is located on the peripheral side of the ceramic body. It is difficult to fully spray glaze at the angle between the glazed surface and the bottom side of the ceramic body, that is, the edge of the protective coating forms a parting surface. During the use of the induction cooker, the parting surface of the ceramic body is prone to embrittlement after absorbing water, which reduces the strength of the ceramic body. Utility Model Content

[0052] Cooking appliances with control panels, such as induction cookers and infrared cookers, previously used one-piece structures, such as tempered glass. However, this material is expensive and cannot be molded into complex shapes. Therefore, composite control panel structures are now used, which have openings in the main body of the control panel and ceramic bodies placed in the openings. The pots are placed on the ceramic bodies for heating.

[0053] During the ceramic body processing, a protective coating, such as glazing, is applied to the upper and peripheral sides of the ceramic body to form a glazed surface. The glazed surface includes a top glaze section and a peripheral glaze section. The top glaze section is located on the upper side of the ceramic body, and the peripheral glaze section is located on the peripheral side of the ceramic body. It is difficult to fully spray glaze at the angle between the glazed surface and the bottom side of the ceramic body, that is, the edge of the protective coating forms a parting surface. During the use of the induction cooker, the parting surface of the ceramic body is prone to embrittlement after absorbing water, which reduces the strength of the ceramic body.

[0054] This utility model proposes a combined panel assembly 100 for use in the cooking appliance 200.

[0055] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the combined panel assembly 100 includes a panel 1, a ceramic body 2, and an annular sealing portion 4. The panel 1 has a through-hole 11 extending through its inner and outer sides, the through-hole 11 corresponding to the heating device. The ceramic body 2 is mounted at the through-hole 11, and has an outer end face, an inner end face, and a side surface. The inner end face corresponds to the heating device, enabling the heating device to heat a cookware placed on the ceramic body 2. A protective coating 3 is provided at least on the outer end face, the edge of the protective coating 3 forming on the side surface. The annular sealing portion 4 surrounds the periphery of the ceramic body 2, and the annular sealing portion 4 at least covers the edge of the protective coating 3.

[0056] The technical solution of this utility model, by using the annular sealing part 4 to cover the edge of the protective coating 3, achieves waterproof sealing of the edge of the protective coating 3, reduces water absorption of the ceramic body 2 at the edge of the protective coating 3, reduces water absorption embrittlement of the ceramic body 2, ensures the strength of the ceramic body 2, and improves the overall problem of reduced strength of the ceramic body 2.

[0057] In one embodiment, the inner end face is at least partially recessed, which can reduce the thickness of the ceramic body 2 at the inner end face and improve the heating effect of the heating device on the cookware on the ceramic body 2.

[0058] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The annular sealing part 4 is tightly disposed between the ceramic body 2 and the panel 1 to seal the junction between the ceramic body 2 and the panel 1. When water is located on the upper side of the panel 1, sealing the junction between the ceramic body 2 and the panel 1 reduces the amount of water flowing through the junction, reduces the amount of water flowing to the edge of the protective coating 3, and reduces the absorption of water by the ceramic body 2.

[0059] In the embodiments of this utility model, the panel 1 can be plastic or tempered glass. Specifically, the panel 1 is preferably tempered glass, which can ensure the strength of the panel 1. Tempered glass is also resistant to high temperatures, which helps to ensure the lifespan of the panel 1.

[0060] In an embodiment of this invention, the edge of the protective coating 3 is disposed adjacent to the inner end face. Preferably, the edge of the protective coating 3 is located at the junction of the side surface and the inner end face. This ensures the coverage of the protective coating 3 on the side surface of the ceramic body 2, reduces water absorption of the ceramic body 2 on the side surface, and ensures the waterproofness of the ceramic body 2 on the side surface.

[0061] In an embodiment of this invention, the outer end face of the ceramic body 2 protrudes beyond the outer side of the panel 1. When a cookware is placed on the ceramic body 2, a gap exists between the cookware and the panel 1, forming a heat-insulating gap between them. When the cooking appliance heats the cookware, the maximum temperature of the outer surface of the panel 1 is reduced, lowering the temperature resistance requirement of the panel 1 and thus increasing the range of materials that can be selected for the panel 1, which helps to reduce the cost of the panel 1.

[0062] In the embodiments of this utility model, the protective coating 3 includes a glaze layer. Obviously, this design is not limited to this. The protective coating 3 can also be a coating of other materials, as long as it can protect the ceramic body 2 and is resistant to high temperature.

[0063] In an embodiment of this utility model, the ceramic body 2 is at least partially disposed within the through-hole 11. The through-hole 11 serves to limit the movement of the ceramic body 2, ensuring the stability of its installation.

[0064] In an embodiment of this utility model, the ceramic body 2 covers the outer end of the opening 11, and the outer periphery of the inner end of the ceramic body 2 is supported on the outer side of the panel 1. This increases the height of the outer end face of the ceramic body 2 protruding from the panel 1, and when the cookware is placed on the ceramic body 2, it increases the thickness of the heat insulation gap between the cookware and the panel 1, thereby further reducing the maximum temperature of the outer surface of the panel 1.

[0065] Please see Figure 1 and Figure 3 The annular sealing part 4 includes a first sealing part 41, which is disposed around the periphery of the ceramic body 2 and on the outer side of the panel 1. The bottom side of the first sealing part 41 abuts against the outer side of the panel 1, and the inner side of the first sealing part 41 abuts against the side surface of the ceramic body 2. The first sealing part 41 can seal the junction between the ceramic body 2 and the panel 1 to prevent gaps from forming at the junction between the ceramic body 2 and the panel 1, so that foreign objects, including water, can enter the interior of the cooking appliance from the gaps.

[0066] Specifically, the first sealing part 41 can be fixed to the outer side of the panel 1 by adhesive bonding or external force compression. The ceramic body 2 can be partially disposed inside the passage 11, or the ceramic body 2 can be disposed on the outside of the panel 1, as long as the outer end face of the ceramic body 2 is exposed in the passage 11.

[0067] Please see Figure 1 and Figure 3 The annular sealing part 4 further includes a second sealing part 42, which is located inside the first sealing part 41, and the first sealing part 41 and the second sealing part 42 are integrally formed; the outer periphery of the inner end face of the ceramic body 2 is supported on the outer side of the panel 1, and the second sealing part 42 is disposed between the outer periphery of the inner end face of the ceramic body 2 and the outer side of the panel 1.

[0068] By filling the space between the inner end face of the ceramic body 2 and the panel 1 with the second sealing part 42, the gap between the inner end face of the ceramic body 2 and the panel 1 can be reduced, and the inner end face of the ceramic body 2 can be used to protect the ceramic body 2, reducing the entry of foreign objects, including water, into the cooking appliance; the first sealing part 41 and the second sealing part 42 can effectively cover the edge of the protective coating 3, and overall, reduce the absorption of water by the ceramic body 2.

[0069] In one embodiment of this application, please refer to Figure 4 and Figure 5 A rounded corner segment 21 is formed between the inner end face of the ceramic body 2 and the side surface of the ceramic body 2. A filling gap exists between the rounded corner segment 21 and the panel 1, and the filling gap forms the filling groove. The second sealing part 42 is located in the filling groove. This ensures that the inner end face of the ceramic body 2 abuts against the panel 1, and the first sealing part 41 and the second sealing part 42 cover the edge of the protective coating 3, reducing the supporting effect of the second sealing part 42.

[0070] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The annular sealing part 4 includes a third sealing part 43, which is arranged around the periphery of the ceramic body 2. The ceramic body 2 and the third sealing part 43 are at least partially located inside the passage 11. The side surface of the ceramic body 2 abuts against the inner wall surface of the third sealing part 43, and the outer surface of the third sealing part 43 abuts against the hole wall of the passage 11.

[0071] When water drips into the inlet 11, the third sealing part 43 can seal the side surface of the ceramic body 2 with the hole wall of the inlet 11, reducing the amount of water flowing between the side surface of the ceramic body 2 and the hole wall of the inlet 11, thereby reducing the contact between the edge of the protective coating 3 and water, and reducing the absorption of water by the ceramic body 2.

[0072] In the embodiments of this utility model, please refer to Figure 8 and Figure 9The ceramic body 2 is partially disposed within the passage 11. The annular sealing part 4 includes a first sealing part 41 and a third sealing part 43. The first sealing part 41 is attached to the outer side of the panel 1 and sleeved on the side surface of the ceramic body 2 to seal the edge of the protective coating 3 of the ceramic body 2 and the junction of the ceramic body 2 and the panel 1. The third sealing part 43 is disposed between the inner sidewall of the passage 11 and the side surface of the ceramic body 2 to seal the gap between the two. Therefore, in this embodiment, two seals are achieved, resulting in a better sealing effect. Preferably, the first sealing part 41 and the third sealing part 43 are sealant for easy installation.

[0073] In an embodiment of this utility model, the annular sealing part 4 includes a sealing ring. Specifically, the sealing ring is preferably a silicone ring. When the cooking appliance heats the pot, the temperature of the ceramic body 2 rises. The silicone ring has good high-temperature resistance and can withstand the temperature rise of the ceramic body 2.

[0074] In an embodiment of this utility model, the annular sealing part 4 includes a sealant. The sealant has good fluidity and can effectively fill the tiny gaps between the ceramic body 2 and the panel 1, reducing the water absorption of the ceramic body 2. The sealant includes silicone sealant, which has good waterproof effect; the silicone sealant has good high-temperature resistance, and can withstand the temperature rise of the ceramic body 2 when the cooking appliance heats the pot.

[0075] In an embodiment of this invention, the annular sealing part 4 includes an annular waterproof membrane disposed on the ceramic body 2, and the annular waterproof membrane is at least partially disposed at the edge of the protective coating 3. The waterproof membrane provides waterproofing to the edge of the protective coating 3, reducing water absorption by the ceramic body 2 at the edge of the protective coating 3.

[0076] Furthermore, in one embodiment of this application, the annular waterproof membrane comprises a transparent waterproof membrane. The transparent waterproof membrane can reduce obstruction of the protective coating. Specifically, the transparent waterproof membrane comprises a transparent waterproof paint.

[0077] Please see Figure 1 and Figure 2 This utility model also proposes a cooking appliance 200, which includes a main body and a heating device. The main body includes the combined panel assembly 100, the specific structure of which is described in the above embodiments.

[0078] The cooking appliance 200 also includes a base 5 and a top cover 6. The base 5 has an opening at its upper end, and the top cover 6 covers the opening of the base 5. The ceramic body 2 and the panel 1 are both located on the top side of the top cover 6, and the top cover 6 has a through hole corresponding to the ceramic body 2.

[0079] The cooking appliance 200 includes an induction cooker, and the heating device includes an electromagnetic heating device. Specifically, the electromagnetic heating device includes an electromagnetic coil 51, which is disposed in the base 5 and is positioned corresponding to the ceramic body 2.

[0080] Please see Figure 2 The cooking appliance 200 also includes a main board 52, a display board 53, a bracket 54, a fan 57, a power cord 55, and silicone feet 56.
