[0005] The present application provides a cooking appliance, comprising:

[0006] A housing having an opening;

[0007] A coil disk, disposed in the housing and opposite to the opening;

[0008] a panel located at the opening;

[0009] An insulating sheet is located between the coil disk and the panel, the insulating sheet is sealed and connected to the opening, the distance between the insulating sheet and the coil disk in the thickness direction of the insulating sheet is greater than or equal to 2 mm and less than 3.5 mm, and the thickness of the insulating sheet is greater than or equal to 1 mm and less than or equal to 5 mm.

[0010] In order to meet the basic bearing capacity and comply with the impact test of the cookware, the cooking utensil provided by the present application has an increase in the thickness of the panel itself, and the distance between the coil disk and the cookware also increases. Therefore, in order to avoid the increase in the distance between the coil disk and the cookware, which affects the heating power and energy efficiency of the cookware on the cookware, the installation height of the coil disk also needs to be increased. An insulating sheet is provided between the coil disk and the shell. The insulating sheet has insulation, pressure resistance and waterproof properties, and can be used to meet the safety test of the cooking utensil.

[0017] The second mounting portion can be used to mount the panel. The first mounting portion is located on the side of the second mounting portion facing the coil disk, and a gap for accommodating the insulating sheet can be provided between the first mounting portion and the second mounting portion, so as to improve the flatness of the mounting panel.

[0018] According to one embodiment of the present application, the second mounting portion is provided with a glue application groove and a glue overflow groove, the glue application groove and the glue overflow groove are recessed toward the direction of the coil disk, and the glue overflow groove is located on the outer side of the glue application groove.

[0019] Among them, the glue groove can be used to accommodate the connecting glue. The connecting glue has fluidity. In order to improve the connection reliability between the panel and the second mounting part, when gluing, the connecting glue located in the glue groove can protrude from the surface of the second mounting part facing the panel. The overflow glue groove can be used to accommodate the connecting glue overflowing from the glue groove. When the panel is placed on the second mounting surface, the panel can press the excess connecting glue into the overflow glue groove. The connecting glue in the overflow glue groove can be used to increase the contact area between the panel and the second mounting part to improve the connection stability between the two.

[0020] In addition, the excess connecting glue flowing into the glue overflow groove can also reduce the possibility that after the connecting glue is cured, part of the connecting glue protrudes from the surface of the second mounting part facing the panel, resulting in uneven panel installation, and can also reduce the possibility that part of the connecting glue protrudes from the surface of the second mounting part and affects the sealing effect between the panel and the shell.

[0052] 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

[0053] 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.

[0054] 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. During operation, 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.

[0055] The panel is a key component of the cooking utensil and supports the pot. When the user uses the cooking utensil 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.

[0056] Cooking utensils need to undergo safety tests before leaving the factory. Safety tests for cooking utensils usually test insulation and water resistance. When panels are made of low-cost materials, it is difficult to meet safety tests. For example, when the panel is a ceramic panel, due to its large porosity, its strength decreases. When conducting a water overflow pressure test, it is easy for the ceramic panel to break 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.

[0057] Based on the above technical problems, the applicant has improved the structure of the existing cooking utensils. In the present application, an insulating sheet is provided between the coil disk and the shell. The insulating sheet needs to have insulation, pressure resistance and waterproofness, and can be used to meet the safety test of the cooking utensils. The insulation of the insulating sheet can be used to block the conductive parts in the shell, avoiding the problem of internal conductive parts being exposed and causing safety hazards after the panel is broken. In addition, the possibility of liquid flowing into the internal conductive parts through the opening after the panel is broken can be reduced by sealing the opening between the insulating sheet and the shell. The pressure resistance of the insulating sheet can help support the pot after the panel is broken.

[0058] When a panel made of a lower-cost material is used, in order to meet the basic load-bearing capacity and comply with the impact test of the cookware, the thickness of the panel itself increases, and the distance between the coil disk and the cookware also increases. Therefore, in order to avoid the increase in the distance between the coil disk and the cookware, which affects the heating power and energy efficiency of the cooking utensil on the cookware, the installation height of the coil disk also needs to be increased. The present application provides a thickness of an insulating sheet so that when the distance between the coil disk and the insulating sheet is greater than or equal to 2 mm and less than 3.5 mm, it can meet the safety test of the cooking utensil. The thickness of the insulating sheet is greater than or equal to 1 mm and less than or equal to 5 mm.

[0059] The cooking appliance provided in the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

[0060] 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 and an insulating sheet 140 .

[0061] See also Figure 3 and Figure 4As shown, the housing 110 is provided with an opening 110a. The coil disk 120 is arranged inside the housing 110 and opposite to the opening 110a. The panel 130 is located at the opening 110a. The insulating sheet 140 can be located between the coil disk 120 and the panel 130. The insulating sheet 140 is sealed and connected to the opening 110a. The distance k between the insulating sheet 140 and the coil disk 120 in the thickness direction Z of the insulating sheet 140 is greater than or equal to 2 mm and less than 3.5 mm, and the thickness of the insulating sheet 140 is greater than or equal to 1 mm and less than or equal to 5 mm.

[0062] Among them, the distance k between the insulating sheet 140 and the coil disk 120 can be understood as an insulating distance. That is, the larger the distance k between the 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 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. Therefore, in the embodiment of the present application, when the distance k between the insulating sheet 140 and the coil disk 120 is greater than or equal to 2 mm and less than 3.5 mm, setting the thickness of the insulating sheet 140 to be greater than or equal to 1 mm and less than or equal to 5 mm can meet the safety test.

[0063] When the distance k between the insulating sheet 140 and the coil disk 120 is small, the insulating sheet 140 needs to have a larger thickness to isolate the internal coil disk 120 through the insulating sheet 140, thereby meeting the safety test. For example, when the distance k between the insulating sheet 140 and the coil disk 120 is 2 mm, the thickness of the insulating sheet 140 can be 3 mm, 4 mm, or 5 mm.

[0064] Similarly, when the distance k between the insulating sheet 140 and the coil disk 120 is large, the insulating sheet 140 may have a smaller thickness. For example, when the distance k between the insulating sheet 140 and the coil disk 120 is close to 3.5 mm, the thickness of the insulating sheet 140 may be 1 mm.

[0065] In some examples, the insulating sheet 140 in the embodiment of the present application can pass the 3000V withstand voltage test. Therefore, when the safety test is met, the thickness of the insulating sheet 140 can be set as small as possible to reduce the material cost of the insulating sheet 140, thereby helping to reduce the total cost of the cooking utensil 100. For example, the thickness of the insulating sheet 140 can preferably be 1 mm.

[0066] In some examples, the insulating sheet 140 of the present application may be, but is not limited to, a mica sheet. Mica sheets have good insulation, pressure resistance, and waterproof properties, and are relatively low in cost.

[0067] In some possible implementations, see Figures 4 to 6As shown, the inner wall 110 b of the opening 110 a in the embodiment of the present application may be provided with a first mounting portion 111 . The insulating sheet 140 is disposed on the first mounting portion 111 .

[0068] The first mounting portion 111 of the embodiment of the present application may protrude from the inner wall 110 b of the opening 110 a , and the first mounting portion 111 may have a surface facing the panel 130 for supporting the insulating sheet 140 .

[0069] The surface of the first installation portion 111 facing the panel 130 is a plane, so as to maintain the installation flatness of the insulation sheet 140 .

[0070] In some possible implementations, see Figure 4 and Figure 6 As shown, the inner wall 110b of the opening 110a of the embodiment of the present application may also be provided with a positioning portion 100a. The positioning portion 100a may be located on the side of the first mounting portion 111 facing the panel 130. A positioning groove 100b is provided on the insulating sheet 140. The positioning portion 100a may be located in the positioning groove 100b. The positioning portion 100a and the positioning groove 100b may be matched and connected.

[0071] In some examples, the positioning portion 100a of the embodiment of the present application may protrude from the inner wall 110b of the opening 110a. When the insulating sheet 140 is placed on the first mounting portion 111, the positioning groove 100b on the insulating sheet 140 may correspond to the positioning portion 100a on the opening 110a to preliminarily position the insulating sheet 140.

[0072] In some examples, the positioning portion 100a can be disposed on one of the inner walls 110b of the opening 110a, so that the insulating sheet 140 can have a fixed installation direction through the cooperation between the positioning portion 100a and the positioning groove 100b. The positioning portion 100a and the positioning groove 100b can realize the anti-mistake installation of the insulating sheet 140, and prevent the insulating sheet 140 from being installed upside down and affecting the working performance of the cooking utensil 100. Specifically, when the direction of the insulating sheet 140 is placed incorrectly, the insulating sheet 140 cannot be installed flatly on the first installation portion 111, and the installation direction of the insulating sheet 140 needs to be readjusted.

[0073] In some examples, when the positioning groove 100b of the insulating sheet 140 corresponds to the positioning portion 100a of the opening 110a, there may be a gap between the outer edge of the insulating sheet 140 and the inner wall 110b of the opening 110a. The gap between the outer edge of the insulating sheet 140 and the inner wall 110b of the opening 110a can provide an installation gap for the insulating sheet 140 on the one hand to improve the installation convenience of the insulating sheet 140, and on the other hand, it can also be used to accommodate sealant. During the assembly process of the insulating sheet 140, a sealant can be used to fill the gap so that the insulating sheet 140 and the opening 110a are sealed and connected by the sealant.

[0074] The sealant of the embodiment of the present application can be used to seal the gap between the insulating sheet 140 and the opening 110a, so as to reduce the possibility of liquid flowing into the conductive components inside the housing 110 through the gap when the panel 130 is broken. In addition, the sealant can also have the function of fixing the insulating sheet 140. The sealant can fix the insulating sheet 140 to the first mounting portion 111, thereby reducing the possibility of the insulating sheet 140 moving and affecting the sealing effect at the gap.

[0075] In some examples, the sealant of this embodiment may be, but is not limited to, silicone sealant.

[0076] In some other examples, the inner wall 110b of the opening 110a may be provided with a positioning groove 100b. The insulating sheet 140 may be provided with a positioning portion 100a. The positioning portion 100a is matched and connected with the positioning groove 100b.

[0077] In some possible implementations, see Figure 5 and Figure 6 As shown, the housing 110 of the embodiment of the present application may be provided with a second mounting portion 112. The panel 130 may be provided on the second mounting portion 112. The first mounting portion 111 is located on the inner side of the second mounting portion 112. Along the thickness direction Z of the insulating sheet 140, the first mounting portion 111 may be located on a side of the second mounting portion 112 facing the coil disk 120.

[0078] The first mounting portion 111 being located inside the second mounting portion 112 may mean that, along the thickness direction Z of the insulating sheet 140 , the orthographic projection of the first mounting portion 111 is located inside the orthographic projection of the second mounting portion 112 .

[0079] The second mounting portion 112 may be used to mount the panel 130. A gap is provided between the first mounting portion 111 and the second mounting portion 112 along the thickness direction Z of the insulating sheet 140. The gap between the first mounting portion 111 and the second mounting portion 112 may be the same as the thickness of the insulating sheet 140. When the insulating sheet 140 is sealed and connected to the opening 110a, the panel 130 may cover the second mounting portion 112 and be sealed and connected to the second mounting portion 112.

[0080] In some examples, after the insulating sheet 140 is sealed and connected to the opening 110 a , the surface of the insulating sheet 140 facing the panel 130 may be flush with the surface of the second mounting portion 112 facing the panel 130 , so as to improve the flatness of the installation of the panel 130 .

[0081] In some examples, after the panel 130 is installed on the second installation portion 112 , the surface of the panel 130 away from the coil disk 120 may be flush with the outer surface of the housing 110 to improve the aesthetics of the cooking appliance 100 .

[0082] In some examples, the opening 110a of the housing 110 may be a square hole. The panel 130 may be a square structure, which is not limited in this embodiment.

[0083] In some possible implementations, see Figure 6 and Figure 7 As shown, the second mounting portion 112 of the embodiment of the present application may be provided with a glue groove 112a and a glue overflow groove 112b. The glue groove 112a and the glue overflow groove 112b may be recessed toward the coil disk 120. The glue overflow groove 112b is located outside the glue groove 112a.

[0084] The glue groove 112a and the overflow glue groove 112b of the embodiment of the present application can be located on the surface of the second mounting portion 112 facing the panel 130. Among them, the glue groove 112a can 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 mounting portion 112, when gluing, the connecting glue located in the glue groove 112a can protrude from the surface of the second mounting portion 112 facing the panel 130. The overflow glue groove 112b can be used to accommodate the connecting glue overflowing from the glue groove 112a. When the panel 130 is placed on the second mounting surface, the panel 130 can press the excess connecting glue into the overflow glue groove 112b. The connecting glue in the overflow glue groove 112b can be used to increase the contact area between the panel 130 and the second mounting portion 112 to improve the connection stability between the two.

[0085] In addition, the excess connecting glue flowing into the glue overflow groove 112b can also reduce the possibility that after the connecting glue is cured, part of the connecting glue protrudes from the surface of the second mounting portion 112 facing the panel 130, resulting in uneven installation of the panel 130. It can also reduce the possibility that part of the connecting glue protrudes from the surface of the second mounting portion 112 and affects the sealing effect between the panel 130 and the shell 110.

[0086] In some examples, the glue groove 112a and the glue overflow groove 112b can both be closed annular grooves. The glue groove 112a can be arranged along the outer side of the opening 110a. The glue overflow groove 112b can be arranged along the outer side of the glue groove 112a.

[0087] In some possible implementations, see Figure 3 and Figure 4 As shown, the cooking appliance 100 of the present embodiment may further include a sensor assembly 150. An opening 140a is provided on the insulating sheet 140, and one end of the sensor assembly 150 may pass through the opening 140a to abut against the surface of the panel 130 facing the coil disk 120.

[0088] The sensor assembly 150 of the embodiment of the present application can be used to monitor the temperature on the panel 130 to control the heat provided to the pot by the cooking appliance 100 through the control panel. One end of the sensor assembly 150 directly abuts against the panel 130, thereby improving the accuracy of the sensor assembly 150 in monitoring the temperature.

[0089] For some examples, see Figure 3 As shown, along the thickness direction Z of the insulating sheet 140, the end of the sensor assembly 150 facing the panel 130 may be an interference fit with the panel 130. The interference amount m between the end of the sensor assembly 150 facing the panel 130 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 end of the sensor assembly 150 facing the panel 130 and the panel 130 may be 2.5 mm.

[0090] It is understood that, since the end of the sensor assembly 150 facing the panel 130 passes through the opening 140a on the insulating sheet 140, the size of the opening 140a on the insulating sheet 140 is greater than or equal to the size of the end of the sensor assembly 150 facing the panel 130. In some examples, the size of the opening 140a on the insulating sheet 140 may be greater than or equal to 5 mm and less than or equal to 30 mm. Exemplarily, the size of the opening 140a may be 10 mm.

[0091] In some possible implementations, see Figure 3 As shown, the sensor assembly 150 may include a sensor 151 and a silicone member 152. The silicone member 152 may be sleeved on the outside of the sensor 151. Along the thickness direction Z of the insulating sheet 140, the sensor 151 passes through the opening 140a to abut against the panel 130. The silicone member 152 may be used to seal the opening 140a.

[0092] In some examples, the sensor assembly 150 of the embodiment of the present application may be located at the center of the coil disk 120. The silicone member 152 may isolate the coil disk 120 and the sensor 151 to reduce the effect of heating of the coil disk 120 on the sensor 151.

[0093] Furthermore, the silicone member 152 can generate elastic deformation. The insulating sheet 140 can press the silicone member 152, and the silicone member 152 generates compression deformation to seal the opening 140a.

[0094] In some examples, a ceramic cap may be provided on the side of the sensor 151 facing the panel 130 along the thickness direction Z of the insulating sheet 140. The ceramic cap may pass through the opening 140a to abut against the panel 130. The outer diameter of the ceramic cap may be smaller than the size of the opening 140a.

[0095] In some possible implementations, see Figure 3 As shown, the surface of the silicone rubber member 152 facing the panel 130 of the embodiment of the present application may be provided with a sealing protrusion 1521. The sealing protrusion 1521 is pressed tightly between the insulating sheet 140 and the coil disk 120.

[0096] In this embodiment, the sealing protrusion 1521 of the silicone member 152 may be interference fit with the surface of the insulating sheet 140 facing the coil disk 120. The sealing protrusion 1521 may generate compression deformation between the insulating sheet 140 and the coil disk 120 to seal the opening 140a on the insulating sheet 140, so that liquid is not easy to enter the housing 110 through the opening 140a.

[0097] In some examples, the sealing protrusion 1521 can be a closed annular structure. The sealing protrusion 1521 can be located outside the opening 140a. When the panel 130 is broken, the liquid falls on the insulating sheet 140, and the silicone member 152 is correspondingly arranged below the opening 140a, so the liquid can fall on the silicone member 152 through the opening 140a. However, since the sealing protrusion 1521 is located outside the opening 140a, that is, the inner diameter of the sealing protrusion 1521 is larger than the diameter of the opening 140a, the sealing protrusion 1521 can prevent the liquid from diffusing outward and entering the housing 110, so as to achieve sealing of the opening 140a.

[0098] In some examples, the interference n between the sealing protrusion 1521 and the insulating sheet 140 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 sealing protrusion 1521 and the insulating sheet 140 may be 0.8 mm.

[0099] In some achievable embodiments, the panel 130 of the embodiment of the present application may be a ceramic panel 130 .

[0100] The surface of the panel formed by grinding the microcrystalline glass is smooth and aesthetically pleasing. The microcrystalline glass panel 130 has good thermal stability, high insulation, and good chemical corrosion resistance and wear resistance. However, the cost of the microcrystalline glass panel is high, resulting in a high overall cost of the cooking utensil 100. Therefore, the panel 130 of this embodiment can adopt a low-cost ceramic panel, and the cooking utensil 100 can meet the safety test through the insulating sheet 140, thereby reducing the cost.

[0101] In some achievable embodiments, the thickness of the ceramic panel may be greater than or equal to 4.5 mm and less than or equal to 8 mm.

[0102] The thickness of the ceramic panel of the embodiment of the present application can be larger to meet the test of the impact of the cookware. The thickness of the ceramic panel of the embodiment of the present application can be 6.5 mm.
