[0030] In some technical solutions, optionally, the side of the pot body away from the containing cavity is provided with a pressing edge, and the pressing edge and the inner wall of the recess enclose the mounting groove, and part of the pressing edge is located between the fixing member and the mounting part.
[0031] In the technical scheme, the side of the pot body away from the containing cavity is provided with a pressing edge, and optionally, one end of the pot body is outwardly bent to form the pressing edge.
[0032] In some technical schemes, the utensil body further comprises a pot body, the outer pot and the mounting seat are arranged inside the pot body, the side of the pot body away from the containing cavity is further provided with a turned edge, the turned edge is connected with the pot body, and the turned edge and the pressing edge are respectively located at two ends of the pot body in the height direction of the utensil body.
[0033] In the technical scheme, the utensil body further comprises a pot body, and specifically, the outer pot and the mounting seat are arranged inside the pot body, and optionally, the pot body comprises an outer shell cover.
[0034] It can be understood that the pot body is generally a metal piece, and due to the process requirement of the turned edge of the metal outer pot, the width of the bottom pressing edge cannot be greater than the width of the top turned edge, that is, the width of the top turned edge is greater than or equal to the width of the bottom pressing edge, that is, the width of the bottom pressing edge is small, and a screw hole cannot be arranged, so that the bottom pressing edge cannot be assembled with the mounting part, and by arranging the fixing part, the fixing part and the mounting part are connected to form a module, so that the production efficiency of the production line can be improved.
[0035] In some technical schemes, the recess is arranged on the mounting part, and the mounting part comprises a connecting part, the connecting part is arranged on the side of the recess away from the heat conduction plate and connected with the outer pot.
[0036] In the technical scheme, the mounting part comprises a connecting part, and specifically, the connecting part is located outside the recess and connected with the outer pot.
[0037] In some embodiments, the mounting base further comprises a base body and a reinforcing rib, wherein the mounting portion is arranged on the outer periphery of the base body, and the reinforcing rib is arranged on at least one of the base body and the mounting portion.

It can be understood that when the heat-conducting plate and the inner pot are in poor contact, the heat generated by the heating film cannot be quickly transferred to the inner pot and the food, and the heat will form heat accumulation on the microcrystalline glass (heat-conducting plate), thereby causing abnormal film temperature of the heating film. In particular, when the film temperature of the graphene heating film exceeds 400℃, the graphene component in the graphene heating film will oxidize with oxygen in the air, causing the resistance of the graphene heating film to increase, the heating power of the product to decrease, and the cooking performance of the product to be affected.
[0040] By arranging the reinforcing rib on the base body and / or the mounting portion, the structural strength of the mounting base is improved, so that the heat-conducting plate can be placed as horizontally as possible after the cooking appliance is assembled, and the poor contact between the heat-conducting plate and the inner pot can be avoided, which is beneficial to improve the heat transfer efficiency of the heating film, prevent the local temperature of the heating film from exceeding the use temperature due to uneven heat transfer, and prolong the service life of the heating film.

[0042] In this embodiment, the reinforcing rib is arranged on the mounting portion, and specifically, the reinforcing rib is provided with a heat dissipation channel, and the heat dissipation channel is in communication with the mounting groove. It can be understood that the fixing member connected to the mounting portion is generally a plastic member, and the heat generated by the heating film and transferred to the heat-conducting plate can be dissipated outward through the heat dissipation channel on the mounting portion, so that the heat melting of the fixing member due to heat accumulation can be avoided, and the reliability of the cooking appliance can be further improved.
[0043] In some embodiments, the side surface of the heat-conducting plate away from the accommodating cavity and the mounting base form a heat insulation cavity, and the heating film is arranged on one side of the heat-conducting plate located in the heat insulation cavity.
[0044] In the technical solution, the side of the heat-conducting plate away from the containing cavity and the mounting seat form a heat-insulating cavity, and the heat-generating film is arranged on the side of the heat-conducting plate in the heat-insulating cavity, that is, the heat-generating film is arranged on the side of the heat-conducting plate away from the inner pot. Specifically, the heat-generating film generates heat under the condition of being electrified, and the generated heat is transmitted to the inner pot through the heat-conducting plate, and then transmitted to the food in the inner pot, so as to heat and cook the food.
[0045] By arranging the heat-insulating cavity, the heat generated by the heat-generating film and radiated from the side of the heat-generating film away from the heat-conducting plate can be heat-insulated, the heat transmission to the plastic bottom shell and the power board is slowed down, and the heat generated by the heat-generating film is prevented from scalding the plastic bottom shell and the power board to cause a safety hazard, which is beneficial to further improving the reliability of the cooking utensil.
[0046] In some technical solutions, the cooking utensil further comprises a heat-insulating assembly arranged in the heat-insulating cavity and located between the heat-generating film and the cavity wall of the heat-insulating cavity.
[0047] In the technical solution, it is specified that the cooking utensil further comprises a heat-insulating assembly, and specifically, the heat-insulating assembly is arranged in the heat-insulating cavity and located between the heat-generating film and the inner wall of the heat-insulating cavity.
[0048] It can be understood that in the case of the heat-generating film being a graphene heat-generating film, the surface temperature can reach 400℃ when electrified, and the generated heat is transmitted to the side of the heat-conducting plate, and then transmitted to the inner pot through the heat-conducting plate to heat the food in the inner pot. Since the heat-insulating assembly is located on the side of the heat-generating film away from the heat-conducting plate, that is, the heat generated by the heat-generating film and radiated from the side of the heat-generating film away from the heat-conducting plate is heat-insulated, the temperature rise between the heat-generating film and the plastic bottom shell and the power board of the cooking utensil is insulated, the heat generated by the heat-generating film is prevented from scalding the plastic bottom shell and the power board to cause a safety hazard, the basic performance of the cooking utensil is ensured, and the reliability of the cooking utensil is improved.
[0049] In some technical solutions, the heat-generating film comprises a plurality of heat-generating sections, and the plurality of heat-generating sections are arranged at intervals, and at least one heat-generating section is opposite to the heat-insulating assembly in the height direction of the utensil body.
[0050] In the technical solution, it is specified that the heat-generating film comprises a plurality of heat-generating sections, and specifically, the plurality of heat-generating sections are arranged at intervals, and at least one heat-generating section is opposite to the heat-insulating assembly in the height direction of the utensil body, that is, the heating area formed by the heat-generating film is opposite to the heat-insulating assembly, so that the heat generated by the heat-generating film and radiated from the side of the heat-generating film away from the heat-conducting plate can be effectively heat-insulated, the heat-insulating effect of the heat-insulating assembly on the side of the heat-generating film away from the heat-conducting plate is improved, the heat generated by the heat-generating film is prevented from scalding the plastic bottom shell and the power board to cause a safety hazard, and the reliability of the cooking utensil is improved.
[0051] In some embodiments, the heat insulation assembly is provided with an avoidance cavity and an avoidance hole in communication, and the cooking appliance further comprises a temperature measuring member, the temperature measuring member is arranged in the avoidance cavity, one end of the temperature measuring member is inserted into the avoidance hole, and the temperature measuring member is used for detecting the temperature of the heating film.
[0052] In the technical scheme, the cooking appliance further comprises a temperature measuring member, and specifically, the temperature measuring member is used for detecting the temperature of the heating film. It can be understood that, in the case that the heating film is a graphene heating film, the graphene heating film will be oxidized at high temperature, resulting in product heating failure. Moreover, if the film temperature of the graphene heating film is higher than 450 DEG C for a long time, the graphene in the graphene heating film will be oxidized with oxygen in the air, so that the resistance of the graphene heating film is increased and the power is decreased, which affects the performance of the graphene heating film. By arranging the temperature measuring member to detect the film temperature of the heating film, the heating film can be protected, which is beneficial to prolong the service life of the heating film and improve the reliability of the cooking appliance.
[0053] The temperature measuring member is arranged in the avoidance cavity, so that the influence of hot air at the bottom of the heating film on the temperature measuring member is isolated, the accuracy of temperature measurement of the temperature measuring member on the heating film is improved, and the service life of the heating film is further prolonged.
[0054] In addition, one end of the temperature measuring member is arranged in the avoidance hole, so that the temperature measuring member is positioned and the consistency of temperature measurement of the temperature measuring member is ensured, thereby improving the accuracy of temperature measurement of the temperature measuring member on the heating film.
[0055] In some embodiments, the heat insulation assembly is further provided with a limiting groove, and the cooking appliance further comprises a base, the base is arranged in the heat insulation cavity, the temperature measuring member is arranged on the base, and a part of the base is arranged in the limiting groove.
[0056] In the technical scheme, the cooking appliance further comprises a base, and specifically, the base is arranged in the heat insulation cavity, and the temperature measuring member is arranged on the base, so that the temperature measuring member is installed.
[0057] The heat insulation assembly is further provided with a limiting groove, and a part of the base is arranged in the limiting groove, so that the temperature measuring member is limited in the axial direction (the height direction of the appliance body), the consistency of temperature measurement of the temperature measuring member is ensured, the accuracy of temperature measurement of the temperature measuring member on the heating film is improved, and the service life of the heating film is prolonged.
[0058] In some embodiments, the heat insulation assembly comprises a first heat insulation member and a second heat insulation member, and the first heat insulation member is arranged between the second heat insulation member and the heating film.
[0059] In the technical solution, the heat insulation assembly includes the first heat insulation member and the second heat insulation member, specifically, the first heat insulation member is located between the heat generating film and the second heat insulation member, that is, two heat insulation members are arranged on the side of the heat generating film away from the heat conduction plate to combine heat insulation, which is beneficial to improve the heat insulation effect, so as to insulate the temperature rise between the heat generating film and the plastic bottom shell of the cooking utensil and the power board, prevent the heat generated by the heat generating film from scalding the plastic bottom shell and the power board to cause safety hazards, ensure the basic performance of the cooking utensil, and improve the reliability of the cooking utensil.
[0060] In some technical solutions, optionally, the first heat insulation member is a waterproof member; and / or the second heat insulation member is heat insulation cotton or an aerogel member; and / or the thickness of the first heat insulation member is greater than or equal to 0.5 mm and less than or equal to 4 mm; and / or the thickness of the heat insulation assembly is greater than or equal to 5 mm and less than or equal to 30 mm.
[0061] In the technical solution, the second heat insulation member is heat insulation cotton, or the second heat insulation member is an aerogel member, so that effective heat insulation of the heat generated by the heat generating film away from the heat conduction plate can be achieved.
[0062] It can be understood that, since the second heat insulation member is heat insulation cotton or an aerogel, after the cooking utensil works for a long time, the second heat insulation member will adsorb moisture in the air. If the second heat insulation member directly contacts the heat generating film, or the first heat insulation member is not waterproof, the surface of the heat generating film will be wet, which will cause the resistance value of the heat generating film to increase and the heating power to decrease, affecting the heating performance of the product. In addition, in the case that the second heat insulation member is heat insulation cotton, the heat insulation cotton is generally prone to dust falling. If the second heat insulation member directly contacts the heat generating film, the dust falling from the heat insulation cotton will affect the insulation performance of the surface of the heat generating film and the accuracy of the temperature measurement of the heat generating film by the temperature measuring member.
[0063] Since the first heat insulation member is a waterproof member, that is, a waterproof member that does not absorb water is arranged between the second heat insulation member and the heat generating film, so that the heat generating film is not directly contacted with the second heat insulation member, so that the surface of the heat generating film can be kept dry while achieving the heat insulation effect, improving the accuracy of the heat generating film temperature measurement, and thus improving the product performance.
[0064] The thickness of the first heat insulation member is between 0.5 mm and 4 mm, so that the heat insulation effect can be ensured while facilitating the thinning of the cooking utensil.
[0065] The thickness of the heat insulation assembly is between 5 mm and 30 mm, so that the heat insulation effect can be ensured while facilitating the thinning of the cooking utensil.
[0066] In some technical solutions, optionally, the cavity wall of the heat insulation cavity includes a reflective layer.
[0067] In the technical solution, the cavity wall of the heat insulation cavity comprises a reflective layer, and it can be understood that, since the heating film is located in the heat insulation cavity and the heat generated by the heating film is transmitted to the inner pot through the heat conduction plate, by setting the cavity wall of the heat insulation cavity as a reflective layer, the heat radiated by the heating film towards the side away from the heat conduction plate can be reflected to the side where the heat conduction plate is located as much as possible, and then more heat is transmitted to the inner pot through the heat conduction plate, which is beneficial to improving the heating efficiency of the cooking utensil and improving the heating effect.

The specific arrangement can be determined according to actual needs. Since at least part of the sealing member 150 is located between the groove wall of the mounting groove 111 and the heat conduction plate 121, the appliance body 110 is pressed on the sealing member 150 during the production and assembly of the cooking appliance 100, which can buffer the heat conduction plate 121, thereby protecting the heat conduction plate 121 and effectively preventing the heat conduction plate 121 from being broken due to contact with a hard object during production and assembly. In addition, the gap between the groove wall of the mounting groove 111 and the heat conduction plate 121 can be sealed to achieve good waterproof effect, thereby preventing the water and impurities carried by the inner pot 140 from entering the heating film 122 through the gap between the heat conduction plate 121 and the groove wall of the mounting groove 111 during the taking and placing of the inner pot 140, and thereby preventing the heating film 122 from being damaged, and ensuring the performance of the heating film 122.
[0126] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 , in some embodiments, the recess 116 is arranged on the mounting portion 115, and the outer pot 113 includes a pot body 117 and a fixing member 118, wherein the pot body 117 and the heat conduction plate 121 together form the accommodating cavity 130, and the inner wall of the recess 116 and the pot body 117 together form the mounting groove 111, and the fixing member 118 is arranged on the side of the pot body 117 away from the accommodating cavity 130 and connected with the mounting portion 115.

Specifically, the fixing member 118 is sleeved on the outer side of the pot body 117, and the fixing member 118 is connected with the mounting portion 115, thereby realizing reliable assembly between the outer pot 113 and the mounting seat 114, and thereby facilitating improvement of the installation stability and reliability of the heating element 120.
[0128] Optionally, the fixing member 118 includes a plastic member.
[0129] Optionally, the pot body 117 includes a metal pot body.
[0130] Optionally, the fixing member 118 is further provided with a positioning column, and the mounting portion 115 is further provided with a positioning hole, the positioning column being inserted into the positioning hole to play a role of positioning and limiting.
[0131] Optionally, the fixing member 118 is connected with the mounting portion 115 through screws or buckles, so that the outer pot 113, the mounting seat 114, the heat-conducting plate 121 and the heating film 122 are assembled together to form a modular assembly, facilitating production and assembly and being beneficial to improving production efficiency.
[0132] As shown in Figure 1 and Figure 2 , in some embodiments, the side of the pot body 117 away from the containing cavity 130 is provided with a pressing edge 119, the pressing edge 119 and the inner wall of the recess 116 together form the mounting groove 111; wherein a part of the pressing edge 119 is located between the fixing member 118 and the mounting portion 115.
[0133] In this embodiment, it is limited that the side of the pot body 117 away from the containing cavity 130 is provided with the pressing edge 119, and optionally, one end of the pot body 117 is outwardly bent to form the pressing edge 119. Specifically, the pressing edge 119 and the inner wall of the recess 154 form the mounting groove 111, that is, the pressing edge 119 is pressed on the sealing member 150. Since a part of the pressing edge 119 is located between the fixing member 118 and the mounting portion 115, that is, part of the pressing edge 119 is clamped between the fixing member 118 and the mounting portion 115, reliable assembly between the outer pot 113 and the mounting seat 114 can be achieved, thereby being beneficial to improving the installation stability and reliability of the heating member 120.
[0134] Optionally, the fixing member 118 is provided with a plurality of first threaded holes, the mounting portion 115 is provided with a plurality of second threaded holes, and the cooking appliance 100 further comprises a plurality of fasteners, each fastener passing through one first threaded hole and one second threaded hole to connect the mounting portion 115 and the fixing member 118.
[0135] As shown in Figure 4 , Figure 5 , Figure 13 and Figure 14 , in some embodiments, the appliance body 110 further comprises a pot body 270, the outer pot 113 and the mounting seat 114 are arranged inside the pot body 270, the side of the pot body 117 away from the containing cavity 130 is further provided with a turned edge 260, the turned edge 260 is connected with the pot body 270, along the height direction of the appliance body 110, the turned edge 260 and the pressing edge 119 are respectively located at two ends of the pot body 117; wherein along the radial direction of the inner pot 140, the width of the pressing edge 119 is not greater than the width of the turned edge 260.
[0136] In this embodiment, the utensil body 110 is defined to further include a pot body 270, specifically, the outer pot 113 and the mounting seat 114 are arranged in the interior of the pot body 270, and optionally, the pot body 270 includes a shell cover. The side of the pot body 117 away from the containing cavity 130 is further provided with a turned-up edge 260, and the turned-up edge 260 and the pressed edge 119 are respectively located at two ends of the pot body 117 in the height direction, specifically, the turned-up edge 260 is located at the top end, and the pressed edge 119 is located at the bottom end.
[0137] It can be understood that the pot body 117 is generally a metal piece, and due to the process requirement of the turned-up edge of the metal outer pot, the width of the bottom end pressed edge 119 cannot be greater than the width of the top end turned-up edge 260, that is, the width of the top end turned-up edge 260 is greater than or equal to the width of the bottom end pressed edge 119, that is, the width of the bottom end pressed edge 119 is small, and a screw hole cannot be arranged, so that the bottom end pressed edge 119 cannot be assembled with the mounting portion 115 by arranging a screw hole, and by arranging the fixing piece 118, the fixing piece 118 and the mounting portion 115 are connected to form a module, so as to improve the production efficiency of the production line.
[0138] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , in some embodiments, optionally, based on the recess arranged in the mounting portion, the mounting portion 115 includes a connecting portion 160, the connecting portion 160 is arranged on the side of the recess 116 away from the heat conduction plate 121 and connected with the outer pot 113; wherein, along the height direction of the utensil body 110, the side of the heat conduction plate 121 located in the containing cavity 130 is lower than the side of the connecting portion 160 facing the outer pot 113.
[0139] In this embodiment, the mounting portion 115 includes the connecting portion 160, specifically, the connecting portion 160 is located outside the recess 116, and the connecting portion 160 is connected with the outer pot 113. Since the sealing piece 150 is arranged between the outer peripheral end of the heat conduction plate 121 and the groove wall of the mounting groove 111, the height of the side of the heat conduction plate 121 located in the containing cavity 130 is lower than the height of the side of the connecting portion 160 facing the outer pot 113, that is, the top surface of the heat conduction plate 121 is lower than the top surface of the connecting portion 160, thereby reserving installation space for the sealing piece 150, which is conducive to improving the sealing effect between the heat conduction plate 121 and the groove wall of the mounting groove 111.
[0140] As shown in Figure 8 , Figure 9 , Figure 11 and Figure 12 , in some embodiments, optionally, the mounting seat 114 further includes a seat body 170 and a reinforcing rib 180, wherein the mounting portion 115 is arranged on the outer periphery of the seat body 170, and the reinforcing rib 180 is arranged on at least one of the seat body 170 and the mounting portion 115.
[0141] In this embodiment, the mounting seat 114 further comprises a seat body 170 and a reinforcing rib 180, specifically, the seat body 170 is provided with the reinforcing rib 180. Alternatively, the mounting portion 115 is provided with the reinforcing rib 180. Alternatively, the seat body 170 and the mounting portion 115 are respectively provided with the reinforcing rib 180. The specific arrangement can be made according to actual needs.
[0142] By arranging the reinforcing rib 180 on the seat body 170 and / or the mounting portion 115, the structural strength of the seat body 170 and / or the mounting portion 115 can be improved, so that the deformation of the seat body 170 and / or the mounting portion 115 during production and assembly can be avoided, and the poor contact between the heat-conducting plate 121 and the inner pot 140 after assembly can be avoided. It can be understood that when the poor contact between the heat-conducting plate 121 and the inner pot 140 occurs, the heat generated by the heating film 122 cannot be quickly transferred to the inner pot 140 and the food material, and the heat will form heat accumulation on the microcrystalline glass (heat-conducting plate 121), so that the film temperature of the heating film 122 is abnormal, especially in the case of the graphene heating film, when the film temperature exceeds 400℃, the graphene component in the graphene heating film will have an oxidation reaction with oxygen in the air, causing the resistance of the graphene heating film to increase, the heating power of the product to decrease, and the cooking performance of the product to be affected.
[0143] By arranging the reinforcing rib 180 on the seat body 170 and / or the mounting portion 115, the structural strength of the mounting seat 114 is improved, so that the heat-conducting plate 121 can be placed as horizontally as possible after the cooking appliance 100 is assembled, and the poor contact between the heat-conducting plate 121 and the inner pot 140 can be avoided, which is beneficial to improve the heat transfer efficiency of the heating film 122, prevent the local temperature of the heating film 122 from exceeding the use temperature due to uneven heat transfer, and prolong the service life of the heating film 122.
[0144] Optionally, based on that the reinforcing rib 180 is arranged on the seat body 170, the reinforcing rib 180 extends inwardly and protrudes, so that the mounting seat 114 can be placed horizontally during production and assembly, which is beneficial to further improve the production efficiency.
[0145] Optionally, the number of the reinforcing ribs 180 is a plurality.
[0146] As shown in Figure 8 , Figure 9 and Figure 12 , in some embodiments, the reinforcing rib 180 is arranged on the mounting portion 115; the reinforcing rib 180 is provided with a heat dissipation channel 181, and the heat dissipation channel 181 communicates with the mounting groove 111.
[0147] In this embodiment, the reinforcing rib 180 is arranged on the mounting portion 115, and specifically, the reinforcing rib 180 is provided with a heat dissipation channel 181 that is in communication with the mounting groove 111. It can be understood that the fixing member 118 connected to the mounting portion 115 is generally a plastic member. The heat generated by the heating film 122 and transferred to the heat conduction plate 121 can be dissipated outward through the heat dissipation channel 181 on the mounting portion 115, thereby avoiding the accumulation of heat at this location and causing the fixing member 118 to melt due to heat. This is beneficial to further improve the reliability of the cooking utensil 100.
[0148] As shown in Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 13 and Figure 14 , in some embodiments, optionally, a side of the heat conduction plate 121 away from the containing cavity 130 and the mounting seat 114 enclose a heat insulation cavity 190, and the heating film 122 is arranged on a side of the heat conduction plate 121 located in the heat insulation cavity 190.
[0149] In this embodiment, since a side of the heat conduction plate 121 away from the containing cavity 130 and the mounting seat 114 enclose a heat insulation cavity 190, and the heating film 122 is arranged on a side of the heat conduction plate 121 located in the heat insulation cavity 190, that is, the heating film 122 is arranged on a side of the heat conduction plate 121 away from the inner pot 140. Specifically, the heating film 122 generates heat under the condition of being powered on, and the generated heat is transferred to the inner pot 140 through the heat conduction plate 121, and then transferred to the food in the inner pot 140 through the inner pot 140, so as to heat and cook the food.
[0150] By arranging the heat insulation cavity 190, the heat dissipated from the side of the heating film 122 away from the heat conduction plate 121 can be subjected to heat insulation treatment, thereby slowing down the heat transfer to the plastic bottom shell and the power board, preventing the heat generated by the heating film 122 from scalding the plastic bottom shell and the power board and causing safety hazards, and being beneficial to further improve the reliability of the cooking utensil 100.
[0151] As shown in Figure 3 , Figure 6 , Figure 10 , Figure 1 , Figure 4 , Figure 5 and Figure 6 , in some embodiments, optionally, the cooking utensil 100 further comprises a heat insulation assembly 210 arranged in the heat insulation cavity 190 and located between the heating film 122 and the cavity wall of the heat insulation cavity 190.
[0152] In this embodiment, the cooking appliance 100 is further defined as including a heat insulation component 210. Specifically, the heat insulation component 210 is disposed in the heat insulation cavity 190 and is located between the heating film 122 and the inner wall of the heat insulation cavity 190.
[0153] Understandably, when the heating film 122 is a graphene heating film, the surface temperature can reach as high as 400°C when energized. The generated heat is transferred to one side of the heat conduction plate 121 and then to the inner pot 140 to heat the food in the inner pot 140. Since the heat insulation component 210 is located on the side of the heating film 122 away from the heat conduction plate 121, it insulates the heat emitted from the side of the heating film 122 away from the heat conduction plate 121, thus isolating the heating film 122 from the temperature rise between the plastic bottom shell of the cooking appliance 100 and the power board. This prevents the heat generated by the heating film 122 from damaging the plastic bottom shell and the power board, thus avoiding safety hazards. It ensures the basic performance of the cooking appliance 100 and helps improve the reliability of the cooking appliance 100.
[0154] like Figure 7 , Figure 1 and Figure 4 As shown, in some embodiments, optionally, the heating film 122 includes a plurality of heating segments 124, which are spaced apart and at least one heating segment 124 is opposite to the heat insulation component 210 along the height direction of the appliance body 110.
[0155] In this embodiment, the heating film 122 is defined to include a plurality of heating segments 124. Specifically, the plurality of heating segments 124 are spaced apart from each other. Along the height direction of the appliance body 110, at least one heating segment 124 is opposite to the heat insulation component 210. That is, the heating area 250 formed by the heating film 122 is opposite to the heat insulation component 210, thereby effectively insulating the heat emitted from the side of the heating film 122 away from the heat conducting plate 121, improving the heat insulation effect of the heat insulation component 210 on the side of the heating film 122 away from the heat conducting plate 121, further preventing the heat generated by the heating film 122 from damaging the plastic bottom shell and power board and causing safety hazards, which is conducive to improving the reliability of the cooking appliance 100.
[0156] Optionally, each heating segment 124 is electrically connected to the first electrode and the second electrode, respectively.
[0157] Optionally, at least one of the first electrode and the second electrode includes a terminal block and a silver electrode. The silver electrode is electrically connected to the heating section 124, and the terminal block is soldered onto the silver electrode. The mounting base 114 is also provided with a wiring hole that communicates with the heat insulation cavity 190. The terminal block is connected to a power source through the wiring hole.
[0158] like Figure 5 , Figure 6 ,Figure 7 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the heat insulation component 210 is provided with a communicating cavity 211 and a clearance hole 212, and the cooking appliance 100 also includes a temperature measuring element 220, which is disposed in the cavity 211 and one end of the temperature measuring element 220 is inserted into the clearance hole 212 for detecting the temperature of the heating film 122.
[0159] In this embodiment, the cooking appliance 100 further includes a temperature measuring element 220. Specifically, the temperature measuring element 220 is used to detect the temperature of the heating film 122. It is understood that when the heating film 122 is a graphene heating film, the graphene heating film will oxidize at high temperatures, leading to heating failure. Moreover, if the film temperature of the graphene heating film exceeds 450°C for an extended period, the graphene in the film will react with oxygen in the air, causing an increase in resistance and a decrease in power, thus affecting the performance of the graphene heating film. By setting the temperature measuring element 220 to detect the film temperature of the heating film 122, the heating film 122 can be protected, which helps to extend its service life and improve the reliability of the cooking appliance 100.
[0160] The temperature measuring element 220 is located inside the cavity 211, which can isolate the influence of the hot air at the bottom of the heating film 122 on the temperature measuring element 220, improve the accuracy of the temperature measuring element 220 in measuring the temperature of the heating film 122, and help to further extend the service life of the heating film 122.
[0161] In addition, since one end of the temperature measuring element 220 is located inside the clearance hole 212, the temperature measuring element 220 is positioned to ensure the consistency of temperature measurement by the temperature measuring element 220, which in turn helps to improve the accuracy of temperature measurement of the heating film 122 by the temperature measuring element 220.
[0162] Optionally, the temperature sensing element 220 includes a temperature controller.
[0163] like Figure 6 , Figure 7 , Figure 1 , Figure 5 and As shown, in some embodiments, the heat insulation component 210 may optionally be provided with a limiting groove 213, and the cooking appliance 100 may also include a base 230, which is disposed in the heat insulation cavity 190, and a temperature measuring element 220 is disposed in the base 230, with a portion of the base 230 located in the limiting groove 213.
[0164] In this embodiment, the cooking appliance 100 is further defined as including a base 230. Specifically, the base 230 is disposed in the heat insulation cavity 190, and the temperature measuring element 220 is disposed on the base 230, thereby realizing the installation of the temperature measuring element 220.
[0165] The heat insulation assembly 210 further provides a limiting groove 213, and a part of the base 230 is located in the limiting groove 213, so that the temperature measuring piece 220 can be limited in the axial direction (the height direction of the appliance body 110), which is beneficial to ensure the consistency of temperature measurement of the temperature measuring piece 220, and further beneficial to improve the accuracy of temperature measurement of the temperature measuring piece 220 on the heating film 122, and prolong the service life of the heating film 122.
[0166] As shown in , , and indicate that, in some embodiments, optionally, the heat insulation assembly 210 comprises a first heat insulation piece 214 and a second heat insulation piece 215, wherein the first heat insulation piece 214 is located between the second heat insulation piece 215 and the heating film 122.
[0167] In this embodiment, it is defined that the heat insulation assembly 210 comprises the first heat insulation piece 214 and the second heat insulation piece 215, specifically, the first heat insulation piece 214 is located between the heating film 122 and the second heat insulation piece 215, that is, two heat insulation pieces are arranged on the side of the heating film 122 away from the heat conduction plate 121 for combined heat insulation, which is beneficial to improve the heat insulation effect, so as to isolate the temperature rise between the heating film 122 and the plastic bottom shell of the cooking appliance 100 and the power board, prevent the heat generated by the heating film 122 from scalding the plastic bottom shell and the power board to cause safety hazards, ensure the basic performance of the cooking appliance 100, and improve the reliability of the cooking appliance 100.
[0168] In some embodiments, optionally, the first heat insulation piece 214 is a waterproof piece; and / or the second heat insulation piece 215 is a heat insulation cotton or aerogel piece; and / or the thickness of the first heat insulation piece 214 is greater than or equal to 0.5 mm and less than or equal to 4 mm; and / or the thickness of the heat insulation assembly 210 is greater than or equal to 5 mm and less than or equal to 30 mm.
[0169] In this embodiment, the second heat insulation piece 215 is heat insulation cotton, or the second heat insulation piece 215 is an aerogel piece, so that the heat dissipated from the side of the heating film 122 away from the heat conduction plate 121 can be effectively insulated.
[0170] Understandably, since the second heat insulation component 215 is made of heat insulation cotton or aerogel, it will absorb moisture from the air after the cooking appliance 100 has been in use for a long time. If the second heat insulation component 215 is in direct contact with the heating film 122, or if the first heat insulation component 214 is not waterproof, the surface of the heating film 122 will become damp, resulting in increased resistance and decreased heating power, thus affecting the product's heating performance. Furthermore, when the second heat insulation component 215 is made of heat insulation cotton, this cotton is generally prone to shedding dust. If the second heat insulation component 215 is in direct contact with the heating film 122, the dust falling from the cotton will affect the insulation performance of the heating film 122 surface and the accuracy of the temperature measurement of the heating film 122 by the temperature measuring component 220.
[0171] Since the first heat insulation component 214 is a waterproof component, that is, a non-absorbent waterproof component is set between the second heat insulation component 215 and the heating film 122 to avoid direct contact between the heating film 122 and the second heat insulation component 215. This allows the surface of the heating film 122 to be dried while achieving the heat insulation effect, improving the accuracy of the temperature measurement of the heating film 122, and thus improving the product performance.
[0172] The thickness of the first heat insulation element 214 is between 0.5 mm and 4 mm, which can help to make the cooking utensil 100 thinner while ensuring the heat insulation effect.
[0173] The thickness of the heat insulation component 210 is between 5mm and 30mm, which enables the cooking appliance 100 to be made thinner and lighter while ensuring the heat insulation effect.
[0174] Optionally, the thickness of the first heat insulation element 214 is any one of 0.5mm, 1mm, 2mm, 3mm, and 4mm.
[0175] Optionally, the thickness of the thermal insulation component 210 is any one of 5mm, 8mm, 10mm, 15mm, 20mm, and 30mm.
[0176] Optionally, the first thermal insulation element 214 is a mica sheet.
[0177] like and As shown, in some embodiments, optionally, the cavity wall of the heat insulation cavity 190 includes a reflective layer 240.
[0178] In this embodiment, the cavity wall defining the heat insulation cavity 190 comprises a reflective layer 240. It can be understood that, since the heat generating film 122 is located in the heat insulation cavity 190 and the heat generated by the heat generating film 122 is transmitted to the inner pot 140 through the heat conduction plate 121, by arranging the cavity wall of the heat insulation cavity 190 as the reflective layer 240, the heat radiated by the heat generating film 122 towards the side away from the heat conduction plate 121 can be reflected as much as possible to the side where the heat conduction plate 121 is located, so that more heat is transmitted to the inner pot 140 through the heat conduction plate 121, which is beneficial to improve the heating efficiency of the cooking utensil 100 and improve the heating effect.
[0179] Optionally, the mounting seat 114 is a reflective member, so that the cavity wall of the heat insulation cavity 190 is the reflective layer 240.
[0180] Optionally, the mounting seat 114 is a plastic member, and the reflective layer 240 is coated on the cavity wall of the heat insulation cavity 190.
[0181] Optionally, the mounting seat 114 is an aluminum member, or the reflective layer 240 is an aluminum layer. The aluminum material can reflect heat while having high-temperature resistance, which is beneficial to improve the reliability of the cooking utensil 100.
