Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a cooking utensil. Background Art

[0002] Cooking appliances such as induction cookers have the advantages of fast heating, no open flame, safety and convenience, and are increasingly favored and recognized by consumers. The induction cooker includes a panel, a shell and a coil disk, the panel is arranged on the top of the shell, the panel and the shell enclose a cavity, and the coil disk is located in the cavity.

[0003] The panel is a key component of the induction cooker and supports the pot. When users use the induction cooker to heat the pot, the pot may dry burn and the bottom temperature of the pot is high. Therefore, placing the pot on the panel is likely to cause the panel to crack. After the panel is cracked, the liquid in the pot spills on the panel and easily enters the inside of the shell. The liquid flows into the coil disk, power cord and other conductive parts in the shell, which is likely to cause safety hazards. Utility Model Content

[0004] The present application provides a cooking utensil which can solve the problem of potential safety hazards caused by cracked panels and liquid flowing into the shell and contacting conductive parts.

[0005] The present application provides a cooking utensil, comprising: a housing having an opening;

[0006] A coil disk, disposed in the housing and opposite to the opening;

[0007] a panel located at the opening;

[0008] A first insulating sheet, located between the coil disk and the panel, the first insulating sheet being sealed and connected to the opening;

[0009] A second insulating sheet is located between the coil disk and the panel, and an orthographic projection of the second insulating sheet toward the coil disk covers an outer contour of the coil disk.

[0010] In the cooking utensil provided in the present application, the first insulating sheet can seal the opening of the shell to reduce the possibility of liquid entering the shell through the gap between the first insulating sheet and the opening after the panel is broken, so that the waterproof test in the safety test can be met. The second insulating sheet is stacked with the first insulating sheet, so that the overlapping area of ​​the first insulating sheet and the second insulating sheet has good load-bearing and pressure resistance, so as to meet the load-bearing and pressure resistance requirements in the safety test.

[0011] In addition, the coil disk is conductive. During safety testing, the coil disk needs to be subjected to an electric shock test to detect the insulation of the cooking utensil. Therefore, the orthographic projection of the second insulating sheet completely covers the outer contour of the coil disk, which can reduce the possibility of safety hazards caused by leakage of the coil disk through its own insulation.

[0012] According to one embodiment of the present application, along the direction of the first side of the panel, both ends of the second insulating sheet are connected to the inner wall of the opening, and along the direction of the second side of the panel, the size of the second insulating sheet is less than or equal to the size of the first insulating sheet.

[0013] Since the cooker is usually placed corresponding to the coil disk, when the panel breaks, the cooker still falls into the area corresponding to the coil disk. Therefore, the second insulating sheet can only correspond to the area of ​​the coil disk to meet the voltage resistance test requirements, so that the size of the second insulating sheet can be set smaller to save the material cost of the second insulating sheet, which is conducive to reducing the cost of the cooking appliance.

[0014] According to one embodiment of the present application, the distance between the first insulating sheet and the coil disk along the thickness direction of the panel is greater than or equal to 2 mm and less than or equal to 3.5 mm, the thickness of the first insulating sheet is greater than or equal to 0.1 mm and less than or equal to 1 mm, and the thickness of the second insulating sheet is greater than or equal to 0.1 mm and less than or equal to 1 mm.

[0015] The first insulating sheet of the embodiment of the present application is sealed and connected to the opening to meet the waterproof test. The second insulating sheet is correspondingly arranged above the coil disk and can be used to achieve insulation. Therefore, the thickness of the first insulating sheet and the second insulating sheet does not need to be set larger, which is beneficial to reduce material costs and reduce installation difficulty.

[0016] According to an embodiment of the present application, an inner wall of the opening is provided with a first step, the first insulating sheet is arranged on the first step, and the second insulating sheet is arranged on the first insulating sheet.

[0017] The first step can be provided to support the first insulating sheet, so as to maintain the installation stability of the first insulating sheet.

[0018] According to an embodiment of the present application, one of the first insulating sheet and the inner wall of the opening is provided with a first positioning portion, and the other is provided with a first positioning groove that cooperates with the first positioning portion.

[0019] The first insulating sheet can be connected to the housing through the first positioning portion and the first positioning groove, and the first positioning portion can also be used to prevent the first insulating sheet from being installed upside down and affecting the working performance. When the first positioning portion is connected with the first positioning groove, the first insulating sheet is not easy to be displaced in the first positioning portion along the first side of the panel.

[0020] According to an embodiment of the present application, one of the second insulating sheet and the inner wall of the opening is provided with a second positioning portion, and the other is provided with a second positioning groove that cooperates with the second positioning portion.

[0021] The second insulating sheet can be connected to the housing by the second positioning portion and the second positioning groove. The second positioning portion and the second positioning groove cooperate with each other to reduce the displacement of the second insulating sheet along the second side of the panel, which is conducive to maintaining the stability of the second insulating sheet.

[0022] According to an embodiment of the present application, a temperature sensor is further included. A first through hole is formed on the first insulating sheet, a second through hole is formed on the second insulating sheet, and the temperature sensor passes through the first through hole and the second through hole and abuts against the panel.

[0023] The temperature sensor can be avoided by the first through hole and the second through hole so that the temperature sensor can directly contact the panel. The temperature sensor can be used to measure the temperature of the panel to control the heat provided to the pot by the cooking utensil through the control panel. One end of the temperature sensor directly abuts against the panel, which is conducive to improving the accuracy of the temperature sensor in monitoring the temperature.

[0024] According to an embodiment of the present application, a second step is further provided on the inner wall of the opening, and the panel is sealed and connected to the second step;

[0025] A distance between the first step and the second step along a thickness direction of the panel is greater than or equal to a sum of thicknesses of the first insulating sheet and the second insulating sheet.

[0026] After the first insulating sheet and the second insulating sheet are installed in the opening of the housing, the surface of the second insulating sheet facing the panel does not protrude from the surface of the second step used to support the panel, so as to reduce the possibility of a gap between the panel and the second step affecting the sealing effect.

[0027] According to one embodiment of the present application, the diameter of the first through hole is greater than or equal to 5 mm and less than or equal to 30 mm; the diameter of the second through hole is greater than or equal to 5 mm and less than or equal to 30 mm.

[0028] According to an embodiment of the present application, the panel is a ceramic panel; or, the first insulating sheet is a mica sheet, or, the second insulating sheet is a mica sheet.

[0029] Both the ceramic panel and the mica sheet have relatively low costs, and the ceramic panel, the first insulating sheet, and the second insulating sheet can cooperate with each other to meet safety tests, thereby reducing the cost of the cooking appliance.

[0030] In addition to the technical problems solved by the embodiments of the utility model described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the cooking utensils provided by the embodiments of the utility model, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0060] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0061] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0062] Induction cookers, electric ceramic cookers, electric pressure cookers, etc. are commonly used cooking utensils, and the cooking utensils include a panel, a shell, and a coil disk. The panel and the shell can enclose a relatively closed cavity to shield the internal power board, control board, coil disk and other live parts during the working process. Among them, the control board is electrically connected to the coil disk to control the opening and closing of the coil disk through the control board. The coil disk can be an electromagnetic coil. When working, the high-frequency current passing through the coil disk can generate countless closed magnetic field forces. The magnetic lines of force cutting the pot can generate countless small eddy currents to make the pot placed on the panel heat up. When in use, the pot is placed on the panel of the cooking utensil. The cooking utensil can be used to cook the ingredients in the pot.

[0063] The panel supports the pot and is a key component of the cooking utensil. When the user uses the cooking utensil to heat the pot, the pot may sometimes burn dry, and the bottom temperature of the pot is high. Therefore, when the pot is placed on the panel, it is easy for the panel to crack. After the panel is cracked, the liquid in the pot spills on the panel and easily flows into the inside of the shell. The liquid flows into the coil disk, power cord and other conductive parts in the shell, which is easy to cause safety hazards.

[0064] Cooking utensils need to undergo safety tests before leaving the factory. Safety tests for cooking utensils usually test insulation and water resistance. If the panel is cracked, it will be difficult to meet safety requirements, especially when the panel is made of low-cost materials. For example, when the panel is made of ceramic material, since the panel of ceramic material has a large porosity, its strength is reduced. When conducting a water overflow pressure test, it is easy to cause the panel to crack and liquid to flow into the conductive parts in the shell, which can easily affect the working performance of the conductive parts and cause damage to the conductive parts. On the other hand, it is also easy to cause safety hazards.

[0065] Based on the above technical problems, the applicant has improved the structure of the existing cooking utensils. In the embodiment of the present application, two layers of insulating sheets are arranged between the panel and the coil disk. The insulating sheet has insulation, pressure resistance and waterproof properties, and can be used to meet the safety test of the cooking utensils. Both layers of insulating sheets are arranged at the opening of the shell, wherein the first insulating sheet can be used to seal the opening to reduce the possibility of liquid entering the inside of the shell through the opening after the panel is broken. The second insulating sheet is stacked with the first insulating sheet, so as to provide the cooker with better load-bearing and pressure resistance. When the panel is broken, the first insulating sheet and the second insulating sheet can assist in supporting the cooker.

[0066] The cooking appliance provided in the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

[0067] See also Figures 1 to 4 As shown, the cooking appliance 100 according to the embodiment of the present application includes a housing 110 , a coil disk 120 , a panel 130 , a first insulating sheet 140 and a second insulating sheet 150 .

[0068] See also Figure 3 and Figure 4 As shown, the housing 110 is provided with an opening 110a. The coil disk 120 is arranged in the housing 110 and is opposite to the opening 110a. The panel 130 is located at the opening 110a. The first insulating sheet 140 can be located between the coil disk 120 and the panel 130. The first insulating sheet 140 is sealed and connected to the opening 110a. The second insulating sheet 150 is also located between the coil disk 120 and the panel 130, and the orthographic projection of the second insulating sheet 150 toward the coil disk 120 covers the outer contour of the coil disk 120.

[0069] The first insulating sheet 140 of the embodiment of the present application can seal the opening 110a of the housing 110 to reduce the possibility of liquid entering the housing 110 through the gap between the first insulating sheet 140 and the opening 110a after the panel 130 is broken, thereby meeting the waterproof test in the safety test. The second insulating sheet 150 is stacked with the first insulating sheet 140, so the overlapping area of ​​the first insulating sheet 140 and the second insulating sheet 150 has good bearing capacity and pressure resistance, so as to meet the bearing capacity and pressure resistance requirements in the safety test.

[0070] In some examples, the first insulating sheet 140 and the second insulating sheet 150 may be, but are not limited to, a mica sheet. Mica sheets have good insulation, pressure resistance, and waterproof properties, and have low cost.

[0071] In some examples, when the panel 130 is made of low-cost materials, the cooking appliance 100 can meet safety test by providing the first insulating sheet 140 and the second insulating sheet 150. Therefore, the cooking appliance 100 of the embodiment of the present application can have a lower cost.

[0072] In some possible implementations, see Figure 5 As shown, the orthographic projection of the second insulating sheet 150 of the embodiment of the present application toward the coil disk 120 covers the outer contour of the coil disk 120 .

[0073] The coil disk 120 is conductive. During safety testing, the coil disk 120 needs to be subjected to an electric shock test to detect the insulation of the cooking appliance 100. The orthographic projection of the second insulating sheet 150 of the embodiment of the present application can completely cover the outer contour of the coil disk 120, so as to reduce the possibility of safety hazards caused by leakage of the coil disk 120 through its own insulation.

[0074] It should be noted that the first insulating sheet 140 may be located between the second insulating sheet 150 and the panel 130 , or the second insulating sheet 150 may be located between the first insulating sheet 140 and the panel 130 .

[0075] In some possible implementations, see Figure 5 As shown, along the direction X of the first side of the panel 130, both ends of the second insulating sheet 150 may be connected to the inner wall of the opening 110a. Along the direction Y of the second side of the panel 130, the size of the second insulating sheet 150 may be smaller than or equal to the size of the first insulating sheet 140.

[0076] When the cookware is placed on the panel 130, the coil disk 120 and the cookware are usually arranged correspondingly, so that the magnetic lines of force generated by the coil disk 120 can act on the cookware, thereby improving the heating efficiency of the cookware. When the panel 130 is broken, the cookware falls downward under the action of its own gravity. Therefore, the corresponding area above the coil disk 120 needs to have a high pressure resistance, that is, along the thickness direction Z of the panel 130, the second insulating sheet 150 corresponds to the coil disk 120, and the cookware can fall on the overlapping area of ​​the first insulating sheet 140 and the second insulating sheet 150, and the second insulating sheet 150 and the first insulating sheet 140 can jointly support the cookware.

[0077] Since the cookware is usually placed corresponding to the coil disk 120, when the panel 130 breaks, the cookware falls and is still located in the area corresponding to the coil disk 120. Therefore, the second insulating sheet 150 can only correspond to the area of ​​the coil disk 120 to meet the voltage resistance test requirements, so that the size of the second insulating sheet 150 can be set smaller to save the material cost of the second insulating sheet 150, which is conducive to reducing the cost of the cooking utensil 100.

[0078] In some examples, both ends of the second insulating sheet 150 along the direction X of the first side of the panel 130 may be used to fix the second insulating sheet 150. The size of the second insulating sheet 150 along the direction Y of the second side of the panel 130 may be smaller than the size of the first insulating sheet 140.

[0079] In some examples, the second insulating sheet 150 may be a quadrilateral structure. Along the direction X of the first side of the panel 130, the opposite ends of the second insulating sheet 150 may be used to connect to the inner wall of the opening 110a to fix the second insulating sheet 150. Along the direction Y of the second side of the panel 130, the distance between the opposite ends of the second insulating sheet 150 may be equal to the outer diameter of the coil disk 120, so that on the one hand, the insulation and withstand voltage safety tests of the cooking utensil 100 can be met, and on the other hand, the material cost of the second insulating sheet 150 can be reduced.

[0080] In some possible implementations, see Figure 3 and Figure 4 As shown, the second insulating sheet 150 can be arranged on the side of the first insulating sheet 140 facing the panel 130. When the panel 130 is broken, the pot can fall on the second insulating sheet 150. The distance between the first insulating sheet 140 and the coil disk 120 along the thickness direction Z of the panel 130 is greater than or equal to 2 mm and less than or equal to 3.5 mm. The thickness of the first insulating sheet 140 can be greater than or equal to 0.1 mm and less than or equal to 1 mm, and the thickness of the second insulating sheet 150 can be greater than or equal to 0.1 mm and less than or equal to 1 mm.

[0081] Among them, along the thickness direction Z of the panel 130, the distance k between the first insulating sheet 140 and the coil disk 120 can be understood as an insulating distance. That is, the larger the distance k between the first insulating sheet 140 and the coil disk 120, the less likely it is that the panel 130 will contact the internal coil disk 120 when it is broken down. The smaller the distance k between the first insulating sheet 140 and the coil disk 120, the easier it is that the panel 130 will contact the internal coil disk 120 and conduct electricity when it is broken down.

[0082] When the distance k between the first insulating sheet 140 and the coil disk 120 is small, if only the first insulating sheet 140 is used for insulation, the first insulating sheet 140 needs to have a greater thickness to comply with safety regulations. Specifically, when the distance between the first insulating sheet 140 and the coil disk 120 is greater than or equal to 2 mm and less than or equal to 3.5 mm, if only the first insulating sheet 140 is used for insulation, the thickness of the first insulating sheet 140 is at least 1 mm, which is not conducive to cost reduction on the one hand, and is not easy to install on the other hand.

[0083] Since the first insulating sheet 140 of the embodiment of the present application is sealed and connected to the opening 110a to meet the waterproof test, the second insulating sheet 150 is correspondingly arranged above the coil disk 120 and can be used to achieve insulation. Therefore, the thickness of the first insulating sheet 140 and the second insulating sheet 150 does not need to be set larger, which is beneficial to reduce material costs and reduce installation difficulty.

[0084] It is verified through experiments that when the thickness of the first insulating sheet 140 is between 0.1 mm and 1 mm (including 0.1 mm and 1 mm), and the thickness of the second insulating sheet 150 is between 0.1 mm and 1 mm (including 0.1 mm and 1 mm), both can meet the safety test of the cooking utensil 100. For example, the thickness of the first insulating sheet 140 and the second insulating sheet 150 can both be 0.2 mm to more effectively reduce material costs.

[0085] In some possible implementations, see Figure 6 and Figure 7 As shown, the inner wall of the opening 110 a in the embodiment of the present application may be provided with a first step 111 . The first insulating sheet 140 may be disposed on the first step 111 . The second insulating sheet 150 may be disposed on the first insulating sheet 140 .

[0086] The first step 111 of the embodiment of the present application can be used to support the first insulating sheet 140 to maintain the installation stability of the first insulating sheet 140. The second insulating sheet 150 can be placed on the first insulating sheet 140.

[0087] In some examples, a glue area may be provided on the surface of the first step 111 facing the panel 130. Specifically, sealant may be injected into the glue area, and then the first insulating sheet 140 may be fixed to the first step 111. After the sealant solidifies, the first insulating sheet 140 may be sealed and connected to the first step 111, thereby sealing the opening 110a of the housing 110 and reducing the risk of liquid entering the housing 110 through the gap between the first insulating sheet 140 and the first step 111.

[0088] In some possible implementations, see Figure 8 and Fig. 9 As shown, one of the first insulating sheet 140 and the inner wall of the opening 110a in the embodiment of the present application may be provided with a first positioning portion 100a, and the other may be provided with a first positioning groove 100b matched with the first positioning portion 100a.

[0089] The first insulating sheet 140 can be connected to the housing 110 through the first positioning portion 100a and the first positioning groove 100b, and the first positioning portion 100a can also be used to prevent the first insulating sheet 140 from being installed upside down to affect the working performance. When the first positioning portion 100a is connected with the first positioning groove 100b, the first insulating sheet 140 is not easy to be displaced in the first positioning portion 100a along the direction X of the first side of the panel 130.

[0090] In some examples, the first insulating sheet 140 may be provided with a first positioning groove 100b, and the inner wall of the opening 110a may be provided with a first positioning portion 100a. Alternatively, the first insulating sheet 140 may be provided with a first positioning portion 100a, and the inner wall of the opening 110a may be provided with a first positioning groove 100b, which is not limited in the present application.

[0091] In some possible implementations, see Figure 5 , Fig.10 and Fig.11 As shown, one of the second insulating sheet 150 and the inner wall of the opening 110a may be provided with a second positioning portion 100c, and the other may be provided with a second positioning groove 100d that matches the second positioning portion 100c.

[0092] The second insulating sheet 150 can be connected to the housing 110 by the second positioning portion 100c and the second positioning groove 100d. The second positioning portion 100c and the second positioning groove 100d cooperate with each other to reduce the displacement of the second insulating sheet 150 along the direction Y of the second side of the panel 130, which is conducive to maintaining the stability of the second insulating sheet 150.

[0093] In some examples, along the direction X of the first side of the panel 130, the second insulating sheet 150 may have protruding second positioning portions 100c at both ends. The inner wall of the opening 110a may have a second positioning groove 100d. The second positioning portion 100c is located in the second positioning groove 100d.

[0094] Alternatively, the second insulating sheet 150 may be provided with second positioning grooves 100d at both ends. A second positioning portion 100c is protrudingly provided on the inner wall of the opening 110a, and the second positioning portion 100c is located in the second positioning groove 100d.

[0095] For some examples, see Figure 5 , Fig.10 and Fig.11 As shown, the second positioning portions 100c at both ends of the second insulating sheet 150 may be staggered along the direction Y of the second side of the panel 130 to prevent the second insulating sheet 150 from being installed upside down and affecting the working performance.

[0096] In some possible implementations, see Figure 3 and Figure 4 As shown, the cooking appliance 100 may further include a temperature sensor 160. The first insulating sheet 140 may have a first through hole 140a. The second insulating sheet 150 may have a second through hole 150a. The temperature sensor 160 may pass through the first through hole 140a and the second through hole 150a and abut against the panel 130.

[0097] The first through hole 140a and the second through hole 150a of the embodiment of the present application can be used to avoid the temperature sensor 160 so that the temperature sensor 160 can directly contact the panel 130. The temperature sensor 160 can be used to measure the temperature of the panel 130 to control the heat provided to the pot by the cooking utensil 100 through the control panel. One end of the temperature sensor 160 directly abuts against the panel 130, which is conducive to improving the accuracy of the temperature sensor 160 monitoring the temperature.

[0098] For some examples, see Fig.12 The temperature sensor 160 may be provided with a ceramic cap 161 on one side facing the panel 130. The ceramic cap 161 may be passed through the first through hole 140a and the second through hole 150a to abut against the panel 130. The apertures of the first through hole 140a and the second through hole 150a are greater than or equal to the size of the ceramic cap 161.

[0099] For some examples, see Figure 3 As shown, along the thickness direction Z of the panel 130, the surfaces of the ceramic cap 161 and the panel 130 facing each other may be interference fit. The interference amount m between the ceramic cap 161 and the panel 130 may be greater than or equal to 1.5 mm and less than or equal to 4 mm. For example, the interference amount m between the ceramic cap 161 and the panel 130 may be 2.5 mm.

[0100] For some examples, see Fig.12 As shown, a silicone member 170 may be further provided on the outer side of the temperature sensor 160. The silicone member 170 may be correspondingly arranged below the first through hole 140a and the second through hole 150a. The silicone member 170 may generate elastic deformation. Along the thickness direction Z of the panel 130, the first insulating sheet 140 may press the silicone member 170, and the silicone member 170 generates compression deformation to seal the first through hole 140a and the second through hole 150a.

[0101] For example, the surface of the silicone member 170 facing the panel 130 may be provided with a plurality of protrusions 171. The protrusions 171 are pressed to seal the first through hole 140a, thereby reducing the possibility of liquid flowing into the housing 110 through the second through hole 150a and the first through hole 140a after the panel 130 is broken.

[0102] The protrusion 171 may be interference fit with the first insulating sheet 140 and the second insulating sheet 150. The interference n between the second insulating sheet 150 and the protrusion 171 may be greater than or equal to 0.4 mm and less than or equal to 1 mm. For example, the interference n between the protrusion 171 and the second insulating sheet 150 may be 0.5 mm.

[0103] In some examples, the protrusion 171 may be an annular structure. The inner diameter of the annular protrusion 171 may be greater than the diameters of the first through hole 140a and the second through hole 150a.

[0104] In some possible implementations, see Figure 6 and Figure 7 As shown, the inner wall of the opening 110a of the embodiment of the present application may also be provided with a second step 112. The panel 130 is sealed and connected to the second step 112. The distance p between the first step 111 and the second step 112 along the thickness direction Z of the panel 130 may be greater than or equal to the sum of the thicknesses of the first insulating sheet 140 and the second insulating sheet 150.

[0105] The second step 112 can be used to support the panel 130. After the first insulating sheet 140 and the second insulating sheet 150 are installed in the opening 110a of the housing 110, the surface of the second insulating sheet 150 facing the panel 130 does not protrude from the surface of the second step 112 used to support the panel 130, so as to reduce the possibility of a gap between the panel 130 and the second step affecting the sealing effect.

[0106] For some examples, see Fig. 9 As shown, the surface of the second step 112 facing the panel 130 may be provided with a glue groove 112a and a glue overflow groove 112b. The glue groove 112a may be used to accommodate the connecting glue. The connecting glue has fluidity. In order to improve the connection reliability between the panel 130 and the second step 112, when gluing, the connecting glue in the glue groove 112a may protrude from the surface of the second step 112 facing the panel 130. The glue overflow groove 112b may be used to accommodate the connecting glue overflowing from the glue groove 112a. When the panel 130 is placed on the second step 112, the excess connecting glue may be pressed into the glue overflow groove 112b. The connecting glue in the glue overflow groove 112b may be used to increase the contact area between the panel 130 and the second step 112 to improve the connection stability between the two.

[0107] In some achievable embodiments, the diameter of the first through hole 140a may be greater than or equal to 5 mm and less than or equal to 30 mm. The diameter of the second through hole 150a may be greater than or equal to 5 mm and less than or equal to 30 mm.

[0108] In some examples, the diameter of the first through hole 140a and the diameter of the second through hole 150a may be the same. For example, the diameters of the first through hole 140a and the second through hole 150a may both be 10 mm.

[0109] In some embodiments, the panel 130 is a ceramic panel.

[0110] In some examples, the thickness of the ceramic panel may be greater than or equal to 4.5 mm and less than or equal to 8 mm. The thickness of the ceramic panel of the embodiment of the present application may be greater to comply with the cookware impact test. For example, the thickness of the ceramic panel may be 6.5 mm.
