[0082] Example 1

[0083] This embodiment provides an electric grilling device that can grill food while enhancing the food cooking experience and improving the overall performance of the electric grilling device.

[0084] like Figures 1 to 4As shown, the electric grilling device includes a base 6, a grilling pan, and a control module. The grilling pan is detachably mounted on the upper side of the base 6 and has a food-bearing surface for holding food. An electric heating structure is installed inside the grilling pan to heat the food-bearing surface, thereby heating the food on the food-bearing surface. The control module is mounted on the base 6 and is used to control the operation of the electric grilling device. The control module includes a power control unit, which is electrically connected to the electric heating structure to supply power to it.

[0085] The baking pan includes a pan body 1 and a heat insulation cover 3. The upper side of the pan body 1 has a food-bearing surface. The heat insulation cover 3 is installed on the lower side of the pan body 1 and forms a sealed mounting cavity around the pan body 1. The heating element is installed within the mounting cavity. The baking pan also includes a first electrical connector 4, and a second electrical connector 7 is provided on the oven base 6. The first electrical connector 4 passes through the heat insulation cover 3 and is electrically connected to the heating element. The first electrical connector 4 and the second electrical connector 7 are detachably electrically connected. The second electrical connector 7 is electrically connected to the control module.

[0086] By installing a heat insulation cover 3 at the bottom of the baking pan 1, and forming a sealed installation cavity with the baking pan 1, the heating structure is protected from water, oil, or other impurities, thus improving its reliability and facilitating cleaning and maintenance of the baking pan. Simultaneously, a first electrical connector 4 is installed on the baking pan, and a second electrical connector 7 is installed on the oven base 6. The first and second electrical connectors 4 and 7 are detachably connected, further facilitating the overall disassembly and assembly of the baking pan, thus aiding in cleaning and storage. Furthermore, the heat insulation cover 3 provides better support for the baking pan 1, enhancing its overall structural strength and rigidity, reducing the probability of heat deformation, and minimizing heat transfer from the heating structure to the oven base 6, thus preventing heat accumulation and potential burns to the user, and improving the convenience of handling the baking pan.

[0087] It is worth noting that the descriptions of directional terms such as "up" and "down" in the preceding and following text are based on the position of the electric griddle when it is in normal use.

[0088] Handles 65 are provided on opposite sides along the length of the stove base 6 to facilitate the user's movement of the electric grilling device. Support legs 66 are provided at the bottom of the stove base 6 to facilitate its placement. A hinge seat 64 is provided on the rear side of the stove base 6. The electric grilling device also includes a lid 10, which is hinged to the stove base 6 via the hinge seat 64. This allows the lid 10 to rotate and snap onto the upper end of the stove base 6 to form a cooking cavity, facilitating steaming and other cooking operations. The lid 10 can also be flipped open relative to the stove base 6 to expose the grill pan for grilling and other cooking operations. The specific structure of the lid 10 and its connection to the stove base 6 can be referenced from existing technologies, which are not the focus of this utility model and will not be elaborated upon here.

[0089] In one embodiment, the heating element is attached to the back of the pan body 1 and spaced apart from the heat insulation cover 3. The close attachment of the heating element to the pan body 1 shortens the distance between them, thereby enhancing heat conduction from the heating element to the pan body 1 and improving heating efficiency. Furthermore, the spaced-apart arrangement between the heating element and the heat insulation cover 3 creates a mounting cavity, which reduces the transfer of heat from the heating element to the heat insulation cover 3, thus reducing downward radiation of heat from the heating element, minimizing heat loss, and lowering the temperature of the heat insulation cover 3, improving the ease of use of the baking pan.

[0090] To improve the heating effect of the electric heating structure on the food-bearing surface, a heat-reflective layer is provided on the side of the heat insulation cover 3 facing the electric heating structure. Since the heat generated by the electric heating structure radiates upwards and downwards, the heat radiation layer reflects the heat energy radiated to the heat insulation cover 3 in the direction towards the plate 1, preventing the heat insulation cover 3 from overheating. This also improves the heating effect of the electric heating structure on the plate 1 and increases heat energy utilization. In other embodiments, a heat insulation structure can also be provided in the mounting cavity. The heat insulation structure is used to further reduce the conduction of heat from the electric heating structure to the heat insulation cover 3. The heat insulation structure can be, but is not limited to, heat insulation cotton, heat insulation coating, or other structures that can reduce heat conduction.

[0091] In one embodiment, the heating structure includes a thick-film circuit 2. The thick-film circuit 2 has multiple heating elements 211 dispersed at the bottom of the pan body 1. Each heating element 211 can generate heat after being energized, and the heat generated by each heating element 211 radiates upwards and covers part of the food-bearing surface. This ensures that the heat radiation area formed by all the heating elements 211 in the thick-film circuit 2 can roughly cover the entire food-bearing area, improving the heating uniformity of the food-bearing surface by the heating structure. By setting the heating structure as a thick-film circuit 2, it is advantageous to set multiple discrete heating elements 211 to improve the heating uniformity of the food-bearing surface. At the same time, using a thick-film circuit 2 as the heating structure can reduce the footprint of the heating structure, improve the overall structural compactness of the baking pan, and reduce the size and weight of the baking pan. In other embodiments, the heating structure can be a heating wire laid at the bottom of the pan body 1, a heating tube installed at the bottom of the pan body 1, or other types of heating structures.

[0092] like Figure 4 and Figure 5 As shown, in one embodiment, the disk body 1 is provided with at least one heating zone, and the thick film circuit 2 includes a first insulating layer, a heating circuit 21 and a second insulating layer sequentially laid on the back side of the disk body 1. Each heating zone is provided with at least a first heating circuit 21, and each heating circuit 21 includes a plurality of heating devices 211 electrically connected in series. The heat radiation area of ​​the heating circuit 21 covers the corresponding heating zone.

[0093] Adjacent heating elements 211 are connected in series via conductive elements 212, and the heating circuit 21 is connected to the first electrical connector 4 through the conductive elements 212. The heating elements 211 on the same heating circuit 21 are distributed in a serpentine bend to ensure the distribution density of the heating elements 211 while improving the ease of connection between the heating elements 211. The thick film circuit 2 is disposed on the bottom of the disk body 1 by sintering. The forming method of the thick film circuit 2 can be specifically set with reference to the prior art, and this embodiment does not limit or elaborate on it.

[0094] To improve the ease of use of the baking pan and electric grill, in one embodiment, at least two heating zones are provided. The heating circuits 21 of different heating zones are connected in parallel or individually. The control module can control the operation of each heating circuit 21 independently, thereby enabling individual heating of each heating zone, achieving zoned cooking, improving the cooking experience, and reducing energy consumption and saving costs when a large heating zone is not needed. Simultaneously, this arrangement reduces the coverage area of ​​a single heating circuit 21, lowering the processing cost and difficulty of the heating circuit 21. In other embodiments, only one heating zone may be provided.

[0095] In one embodiment, the food-bearing surface has two heating zones, one on the left and one on the right, and two heating circuits 21 are arranged side by side in the left-right direction, that is, each heating circuit 21 heats the corresponding heating zone. In other embodiments, three heating zones can be arranged in the left-right direction, or four heating circuits 21 can be arranged in a rectangular pattern. The number of heating zones and the number and arrangement of heating circuits 21 in each heating zone can be adapted to local cooking habits.

[0096] In one embodiment, each heating zone is provided with one heating circuit 21 to simplify the structure and reduce control difficulty. In other embodiments, each heating zone may be provided with multiple heating circuits 21, and the heat radiation areas of the multiple heating circuits 21 are at least partially overlapping. The control module can control the multiple heating circuits 21 in the same heating zone separately, thereby controlling the heating temperature of the heating zone to meet the adjustment requirements of heating power for different foods or different cooking methods.

[0097] like Figures 5 to 8 As shown, in one embodiment, the plate body 1 includes a support plate portion 11, and an edge portion 12 is formed around the edge of the support plate portion 11. The upper side surface of the support plate portion 11 forms a food-bearing surface. The edge portion 12 prevents food from falling out of the support plate portion 11 and avoids oil from flowing out along the edge of the support plate portion 11 during cooking. The heating structure and the first electrical connector 4 are both located on the lower side surface of the support plate portion 11.

[0098] The support plate 11 has multiple raised ribs 15 stamped from bottom to top. The raised ribs 15 enhance the overall structural strength and rigidity of the pan body 1, reduce the probability of the pan body 1 deforming due to heat, improve the reliability of the baking pan, and help ensure the connection stability and reliability of the first electrical connector 4 and the second electrical connector 7. At the same time, the raised ribs 15 reduce the probability of food sticking to the pan body 1, improving the cooking experience. Furthermore, the upper edge of the rim 12 is folded outward to form a flange 13, and the flange 13 is folded downward and inward to form a folded edge 14. The flange 13 and the folded edge 14 enhance the structural strength and rigidity of the pan body 1 at the opening edge, reduce the probability of the pan body 1 deforming, and facilitate the user's handling of the baking pan, improving the user experience.

[0099] In one embodiment, a thermocouple 8 is disposed on the disk body 1, with each thermocouple 8 corresponding to a heating zone. The thermocouple 8 is located within the setting area of ​​the thick-film circuit 2 and is offset from the heating circuit 21. The thermocouple 8 is used to detect the temperature of the disk body 1, facilitating the control module's control of the operation of the thick-film circuit 2. The terminals of the thermocouple 8 are electrically connected to the first conductive element 212 to transmit the detection signal to the control module. By placing the thermocouple 8 on the disk body 1, the reliability and stability of the contact between the thermocouple 8 and the disk body 1 can be ensured, thereby improving the reliability, accuracy, and sensitivity of temperature measurement, and increasing the temperature measurement response speed. The thermocouple 8 is offset from the heating device 211 and the conductive element 212.

[0100] To improve the stability of the thermocouple 8, it is welded to the back of the disc 1 to ensure reliable contact between the sensing end of the thermocouple 8 and the disc 1, simplifying the installation of the thermocouple 8. Furthermore, a clearance hole is provided on the thick-film circuit 2, and the thermocouple 8 is installed in the clearance hole to avoid interference between the thermocouple 8 and the thick-film circuit 2. The clearance hole is filled with high-temperature sealant to prevent leakage and heat loss. The high-temperature sealant used is an existing high-temperature resistant sealant; this invention does not limit the type of high-temperature sealant.

[0101] In one embodiment, each heating zone is provided with one thermocouple 8 to reduce costs and simplify the connection between the thermocouple 8 and the first electrical connector 4. The thermocouple 8 is preferably located in the central region of the heating zone to improve detection accuracy. In other embodiments, each heating zone may be provided with two or more thermocouples 8.

[0102] The heat insulation cover 3 includes a base plate portion 31 and a side plate portion 32 connected to the periphery of the base plate portion 31. The edge of the side plate portion is folded outward to form a connecting edge portion 33. The base plate portion 31 is spaced apart from the thick film circuit 2, and the connecting edge portion 33 is attached to the support plate portion 11, thereby forming an installation cavity between the support plate portion 11 and the base plate portion 31. To better ensure sealing, the connecting edge portion 33 is welded to the support plate portion 11 of the disk body 1 to prevent water or oil stains from entering the sealed space through the gap between the heat insulation cover 3 and the disk body 1, and to prevent the heat generated by the electric heating structure from leaking out through the gap.

[0103] Furthermore, the heat insulation cover 3 and the tray 1 are fully welded together to further improve the sealing of the connection between the two, facilitating the cleaning of the baking tray. The welding method can be laser welding or other welding methods. In other embodiments, the heat insulation cover 3 can be riveted to the tray 1 or connected with screws. A sealing ring is provided at the connection point between the heat insulation cover 3 and the tray 1 to seal the connection. The heat insulation cover 3 is made of high-temperature resistant materials such as stainless steel or ceramic.

[0104] like Figure 3 , Figure 4 and Figure 9 As shown, in one embodiment, the first electrical connector 4 and the second electrical connector 7 are plugged in and out, that is, the first electrical connector 4 is a male connector and the second electrical connector 7 is a female connector. The male connector and the female connector are plugged in and out to improve the convenience of disassembly and assembly and the stability after connection, thereby ensuring the stability and reliability of information transmission.

[0105] The heat insulation cover 3 has an installation port 311. The first electrical connector 4 includes an upper body 41 and an upper connector 42 disposed on the upper body 41. The upper body 41 is installed on the back side of the heat insulation cover 3, and the upper connector 42 passes through the installation port 311 and is electrically connected to the second electrical connector 7. Specifically, the first electrical connector 4 is sealed to the heat insulation cover 3 by the mounting assembly 5 to avoid gaps at the connection position between the heat insulation cover 3 and the first electrical connector 4, which could lead to water or oil entering the sealed space.

[0106] like Figures 9 to 15 As shown, the mounting assembly 5 includes a heat-insulating support 53 and an annular seal 52. The heat-insulating support 53 is sandwiched between the pan body 1 and the heat insulation cover 3, and the annular seal 52 is arranged around the mounting opening 311 and sandwiched between the heat insulation cover 3 and the upper seat 41. Thus, the annular seal 52 seals the gap between the upper seat 41 and the heat insulation cover 3, reducing the probability of moisture and oil entering the interior of the heat insulation cover 3 through this gap, improving the safety and reliability of the baking pan. The heat-insulating support 53 supports the heat insulation cover 3, reducing the probability of deformation of the heat insulation cover 3 due to heat or other reasons, improving the structural stability of the heat insulation cover 3 at the mounting position of the first electrical connector 4, thereby improving the installation accuracy of the first electrical connector 4, and ultimately ensuring the stability and reliability of the plug-in connection between the first electrical connector 4 and the second electrical connector 7.

[0107] The annular seal 52 is made of high-temperature resistant rubber or silicone, and the heat insulation support 53 is preferably made of ceramic or other materials with heat insulation and support properties.

[0108] In one embodiment, the heat insulation support 53 is arranged in a ring and surrounds the mounting opening 311, and electronic components such as the upper connector 42 of the first electrical connector 4 are located inside the heat insulation support 53. This arrangement can reduce the conduction of heat to the inside of the heat insulation support 53, thereby improving the reliability of the first electrical connector 4. At the same time, the ring-shaped heat insulation support 53 supporting the mounting opening 311 can further enhance the support effect of the heat insulation support 53 on the heat insulation cover 3, and improve the stability and reliability of the first electrical connector 4.

[0109] Mounting assembly 5 includes multiple fixing parts 51 protruding from the bottom of the disk body 1. The fixing parts 51 are detachably fastened to the upper seat 41 by fasteners passing between the fixing parts 51 and the upper seat 41. By using multiple fixing parts 51 to fasten the upper seat 41, the space occupied by the mounting structure of the first electrical connector 4 can be reduced, which is beneficial for avoiding the electronic components on the first electrical connector 4. Fixing parts 51 are provided at both ends of the upper seat 41 along the length direction and on the opposite sides of the upper connector 42 to ensure the installation stability and reliability of the upper seat 41 and the upper connector 42.

[0110] The projection of the fixing component 51 on the disk body 1 is offset from that of the heating circuit 21. Specifically, the thick film circuit 2 has a clearance through hole, which corresponds to the fixing component 51. One end of the fixing component 51 passes through the clearance through hole and is connected to the bottom of the disk body 1. The connection method is preferably welding to ensure the stability of the fixing component 51 while simplifying the connection structure between the fixing component 51 and the disk body 1.

[0111] The fixing component 51 includes a fixing post 511 and a connecting protrusion 512. The connecting protrusion 512 is connected to the upper end of the fixing post 511, and the cross-sectional area of ​​the connecting protrusion 512 is smaller than that of the fixing post 511. The connecting protrusion 512 is inserted into the clearance through hole and welded to the disc body 1. The fixing post 511 is detachably connected to the upper seat body 41. This arrangement can reduce the opening size of the clearance through hole while increasing the size of the fixing post 51, thereby increasing the outer diameter of the fastener that mates with the fixing component 51 and improving the connection stability and reliability of the fastener fastening the fixing component 51 and the upper seat body 41. Specifically, the lower end of the fixing post 511 has a fixing threaded hole, and the upper seat body 41 has a fastening through hole. The fastener is a threaded component.

[0112] The fixing component 51 includes two first fixing components 51a located at both ends of the upper seat 41 along its length and a plurality of second fixing components 51b located between the two first fixing components 51a. The upper seat 41 includes an upper main seat portion 411, with fixing ears 412 protruding outward from both ends of the upper main seat portion 411 along its length. The fixing ears 412 are vertically aligned with the first fixing components 51a, and the fixing ears 412, the heat insulation cover 3, and the first fixing components 51a are fastened together by first fasteners passing through them. The upper main seat portion 411 has a seat fixing post 45 protruding from it, and the seat fixing post 45 is correspondingly arranged with the second fixing components 51b. The seat fixing post 45 and the second fixing components 51b are fastened together by second fasteners passing through them.

[0113] By providing the first fixing component 51a, it is effectively ensured that both ends of the upper seat 41 are not only fastened to the disc 1, but also to the heat insulation cover 3, thereby facilitating the pressing of the annular seal 52 between the heat insulation cover 3 and the upper seat 41, ensuring sealing stability and reliability. By providing the second fixing component 51b, it is effectively prevented that the middle part of the upper seat 41 bulges downward, improving the installation stability and reliability of the first electrical connector 4. It is worth noting that in other embodiments, multiple fixing components 51 can be provided at intervals along the circumference of the annular seal 52.

[0114] In one embodiment, the upper seat 41 has an upward-facing recessed groove. The outer wall of the annular seal 52 fits against the peripheral wall of the recessed groove, thereby effectively limiting the shaking of the annular seal 52 relative to the first electrical connector 4, improving the stability of the annular seal 52, and further enhancing the sealing effect of the annular seal 52. Specifically, the upper main seat 411 includes a seat bottom 4111 and a seat side 4112 connected to the periphery of the seat bottom 4111. The seat bottom 4111 and the seat side 4112 together form a recessed groove. The end of the annular seal 52 away from the disc body 1 abuts against the seat bottom 4111, and the peripheral outer wall of the annular seal 52 fits against the seat side 4112. The seat side 4112 abuts against the side of the heat insulation cover 3 away from the disc body 1. A seat fixing post 45 is provided protruding from the bottom of the recessed groove.

[0115] The bottom of the recessed groove is recessed in a direction away from the disc body 1 to form a recessed platform 4113. The recessed platform 4113 extends along the length direction of the upper seat body 41. The upper connector 42 is installed on the recessed platform 4113. This arrangement can ensure the recessed depth of the recessed groove and the contact between the annular seal 52 and the bottom of the recessed groove, while reducing the overall size of the upper seat body 41, reducing weight, and facilitating the cooperation of the first electrical connector 4 and the second electrical connector 7.

[0116] In one embodiment, the two ends of the annular seal 52 along the length direction are clamped between the fixed ear 412 and the heat insulation cover 3, and the first fastener passes through the annular seal 52, thereby enabling the two ends of the annular seal 52 to be stably and reliably clamped between the upper seat 41 and the heat insulation cover 3 under the fastening action of the first fastener, further improving the stability and reliability of the annular seal 52.

[0117] Specifically, the annular seal 52 includes an annular sealing body 521. Connecting ears 522 protrude from both ends of the sealing body 521 along its length. The connecting ears 522 are sandwiched between the fixing ears 412 and the heat insulation cover 3, while the sealing body 521 is sandwiched between the upper main seat 411 and the heat insulation cover 3. This arrangement facilitates the assembly of the annular seal 52 with the upper seat 41.

[0118] In one embodiment, the inner side of the annular seal 52 presses against the thermal insulation support 53, thereby improving the stability and reliability of the annular seal 52. In other embodiments, the thermal insulation support 53 may be disposed separately from the annular seal 52.

[0119] In one embodiment, the sealing body 521 includes an inner sealing ring portion 5211 and an outer sealing ring portion 5212 connected at their lower ends. The upper end of the outer sealing ring portion 5212 is lower than the upper end of the inner sealing ring portion 5211. A connecting ring portion connects the lower ends of the outer sealing ring portion 5212 and the inner sealing ring portion 5211. The outer sealing ring portion 5212 is sandwiched between the main upper seat 41 and the heat insulation cover 3. The upper end of the inner sealing ring portion 5211 extends into the mounting port 311 and abuts against the heat insulation support member 53.

[0120] To ensure the ease of installation of the thermal insulation support 53, in one embodiment, the thermal insulation support 53 has limiting slots 5321 at both ends along its length. The limiting slots 5321 are vertically through the thermal insulation support 53, and the first fixing component 51a is located in the corresponding limiting slot 5321. Thus, through the cooperation of the two first fixing components 51a with the thermal insulation support 53, the movement of the thermal insulation support 53 along its length and width is restricted, thereby eliminating the need for additional structures to fix the thermal insulation support 53, improving the ease of disassembly and assembly of the thermal insulation support 53, and simplifying the overall structure of the installation assembly 5.

[0121] Two limiting through grooves 5321 are disposed on opposite sides of the heat insulation support 53, thereby improving the ease of cooperation between the heat insulation support 53 and the first fixing component 51a, and improving the processing ease of the limiting through grooves 5321. In other embodiments, the limiting through grooves 5321 can be circular grooves.

[0122] In one embodiment, the thermal insulation support 53 includes a support ring portion 531 in the shape of a racetrack. The two ends of the support ring portion 531 protrude from the length direction and are provided with limiting protrusions 532. Limiting grooves 5321 are formed on the limiting protrusions 532 to facilitate the setting of the limiting grooves 5321 while reducing the overall size of the thermal insulation support 53, thereby reducing cost and weight.

[0123] like Figures 16 to 18As shown, the upper connector 42 has multiple conductive pins 422, which form several power supply pin groups. Each power supply pin group includes two heating pins 422a, and the two terminals of the heating circuit 21 are respectively connected to the two heating pins 422a. In one embodiment, a probe pin 43 is mounted on the upper base 41, and the thermocouple 8 is electrically connected to the probe pin 43. Specifically, a probe pin group is also mounted on the upper base 41, with each probe pin group corresponding to a thermocouple 8. Each probe pin group includes two probe pins 43, and the two terminals of the thermocouple 8 are connected to the two probe pins 43 to connect the thermocouple 8 to the detection circuit. By integrating both the upper connector 42 and the probe pins 43 onto the upper base 41, the integration of the first electrical connector 4 can be improved, the size of the first electrical connector 4 can be reduced, and the footprint can be reduced.

[0124] The upper body 41 is a long strip structure. The upper connector 42 is installed in the middle of the upper body 41 along its length. The two probe pin groups are located at opposite ends of the upper connector 42 along its length. This arrangement helps to reduce the overall size of the first electrical connector 4, improves the ease of installation of the first electrical connector 4 on the disk body 1, and reduces the space occupied. At the same time, placing the upper connector 42 in the middle of its length helps to achieve force balance during insertion and removal. Placing the two probe pin groups on opposite sides of the upper connector 42 helps to facilitate the connection of the two electrical lines and the two thermocouples 8 with the first electrical connector 4, reduces wiring interference, and improves wiring convenience.

[0125] To improve the safety of the thick-film circuit 2, a temperature controller 44 is installed on the upper body 41. The temperature controller 44 is configured one-to-one with the heating zone or heating circuit 21. The temperature controller 44 is connected in series between a heating pin 422a and a terminal of the heating circuit 21, and the other terminal of the heating structure is electrically connected to another heating pin 422a. Thus, the temperature controller 44 is connected in series to the power supply circuit of the heating circuit 21. When the temperature is lower than the preset temperature, the temperature controller 44 conducts the two heating pins 422a to make the power supply circuit of the heating circuit 21 conduct; when the temperature is equal to or higher than the preset temperature, the temperature controller 44 disconnects the power supply to the heating circuit 21, preventing the pan body 1 from being heated to an excessively high temperature and causing damage to the first electrical connector 4, thereby improving the safety of the baking pan.

[0126] The upper connector 42 includes an upper socket 421 mounted on the upper base 41. A power supply pin group is mounted on the upper socket 421. A contact group is mounted on the upper socket 421, with each contact group corresponding to a power supply pin group. Each contact group includes three conductive contacts 423 arranged side-by-side: a ground contact 423c, a neutral contact 423a, and a live contact 423b. The first ends of the neutral contact 423a and the live contact 423b are respectively connected to two heating pins 422a of the corresponding power supply pin group. The second end of the neutral contact 423a is connected to a terminal of the heating structure. The live contact 423b is electrically connected to a tab of the thermocouple 8. The use of conductive contacts 423 to connect to the heating structure ensures stable and reliable contact between the heating structure's terminal and the conductive contacts 423, thereby guaranteeing communication stability and reliability. Specifically, the neutral contact 423a is connected to the end of the conductive element 212 of the heating circuit 21.

[0127] In one embodiment, the upper connector 42 is further provided with a spare pin 422b, which is used for wiring when the user needs functional expansion, so as to better meet the wiring requirements. The spare pin 422b is located between two power supply pin groups. That is, multiple conductive pins 422 are spaced apart along the extension direction of the first electrical connector 4.

[0128] An electrical socket is provided at the bottom of the recessed groove, and a mounting ring 4114 protrudes from the bottom of the recessed groove around the electrical socket. The insertion end of the upper socket 421 is inserted into the mounting ring 4114 and is positioned within the mounting ring 4114. The upper socket 421 has a lower open insertion groove, a conductive pin 422 passes through the bottom of the insertion groove, and a conductive contact 423 is installed on the upper side of the upper socket 421 and connected to the upper end of the conductive pin 422. The conductive contact 423 has a C or V-shaped structure, one end of which is connected to the conductive pin 422, and the other end elastically abuts against the thick film circuit 2.

[0129] To enable the installation and fixation of the upper socket 421, a socket connecting post 46 is provided protruding from the bottom of the recessed groove. At least one socket connecting post 46 is provided on each of the opposite sides of the upper connector 42. Fastening plates extend outward from both ends of the upper socket 421. The fastening plates abut against the upper ends of the socket connecting posts 46, and the fastening plates and the socket connecting posts 46 are connected by fasteners passing through them.

[0130] The temperature controller 44 is positioned between the upper connector 42 and the corresponding probe pin group to facilitate wiring between the upper connector 42 and the temperature controller 44. The temperature controller 44 is preferably a jump-type temperature controller to improve response speed and ensure the safety of the first electrical connector 4. The specific structure and working principle of the temperature controller 44 can be set with reference to existing technology and will not be elaborated here.

[0131] like Figure 10 and Figure 16 As shown, in one embodiment, a mounting plate protrudes from the housing of the thermostat 44, and a temperature control fixing post 47 is provided on the upper body 41. The mounting plate and the temperature control fixing post 47 are connected by a through-connecting connector. Preferably, there are two temperature control fixing posts 47, which are located on opposite sides of the thermostat 44 to ensure the installation stability and reliability of the thermostat 44.

[0132] Furthermore, the connector is a threaded connector, which is screwed onto the temperature control fixing post 47. The upper end of the temperature control fixing post 47 and the mounting plate are spaced apart. An elastic element 49 is sleeved on the threaded connector. The elastic element 49 is pressed between the mounting plate and the temperature control fixing post 47 to apply a downward elastic force to the mounting plate, so that the temperature controller 44 can be tightly attached to the thick film circuit 2, so that the temperature controller 44 can accurately sense the temperature at the thick film circuit 2 and ensure the reliability of the temperature controller 44.

[0133] To facilitate the mounting of the probe pins 43 on the upper seat 41, a mounting base 48 protrudes from the bottom of the recessed groove. The mounting base 48 has two insertion holes that penetrate the upper seat 41. The two probe pins 43 of the same probe pin group are respectively inserted into the two insertion holes. Furthermore, the mounting base 48 includes a vertical base and two insertion portions. The two insertion portions are connected to the side of the vertical base away from the upper connector 42. Each insertion portion has an insertion hole. The vertical base extends vertically to better separate the temperature controller 44 and the probe pins 43.

[0134] like Figures 19 to 22 As shown, in one embodiment, the first electrical connector 4 is installed in the middle of the disk body 1 along its length and located between the two heating zones, that is, the first electrical connector 4 is located between the heating circuits 21 on both sides, thereby naturally separating the two heating zones on both sides through the arrangement of the first electrical connector 4. In other embodiments, the first electrical connector 4 may also be provided at one end of the disk body 1 along its length.

[0135] To improve the ease of setting the baking tray on the oven base 6, the upper end of the oven base 6 is recessed downwards to form a placement groove 611, in which the lower part of the baking tray is accommodated. Thus, the placement groove 611 enables the baking tray to be positioned and installed on the oven base 6. The shape of the placement groove 611 is adapted to the shape of the baking tray to ensure the stability of the baking tray within the placement groove 611.

[0136] To further improve the stability of the baking tray on the oven base 6, guide bosses 34 are provided on the baking tray, with at least two guide bosses 34 spaced apart. Guide grooves 6121 are provided on the oven base 6, with each guide groove 6121 corresponding to a guide boss 34. The guide bosses 34 are inserted into the guide grooves 6121 to further guide the installation of the baking tray. Guide bosses 34 protrude from the heat insulation cover 3, with one guide boss 34 at each of the four corners of the heat insulation cover 3 to ensure guiding stability and reliability. Furthermore, the guide bosses 34 are formed by pressing the bottom of the heat insulation cover 3 downwards to reduce processing difficulty and improve the overall structural strength and rigidity of the heat insulation cover 3. A guide recess 612 is formed by pressing the upper end of the oven base 6 downwards, and the cavity of the guide recess 612 forms the guide groove 6121.

[0137] The lower end of the guide boss 34 is lower than or flush with the lower end of the first electrical connector 4, so that when the baking tray is assembled onto the oven base 6, the guide boss 34 first engages with the guide groove 6121 to guide the installation of the baking tray, thereby providing guidance for the plugging and unplugging connection of the first electrical connector 4 and the second electrical connector 7, ensuring the installation reliability of the first electrical connector 4 and the second electrical connector 7, and improving assembly efficiency.

[0138] The guide boss 34 is preferably a tapered boss that is larger at the top and smaller at the bottom, and the guide groove 6121 is a tapered groove. This allows the guide boss 34 to gradually tighten its fit when inserted into the guide groove 6121, improving the ease of placing and removing the baking tray and the stability after installation. In one embodiment, two guide bosses 34 are provided at both ends of each first side, that is, the four guide bosses 34 are arranged in a rectangular pattern to improve positioning reliability.

[0139] In one embodiment, the second electrical connector 7 is disposed at the middle of the furnace base 6 along its length, so that the position of the second electrical connector 7 is adapted to that of the first electrical connector 4. The second electrical connector 7 is installed on the groove wall of the placement groove 611 and is detachably connected to the furnace base 6 to facilitate the installation, maintenance, and replacement of the second electrical connector 7. In other embodiments, the first electrical connector 4 can be disposed at the end of the baking tray, in which case the second electrical connector 7 is also disposed at the end of the baking tray, mainly ensuring that the positions of the first electrical connector 4 and the second electrical connector 7 are aligned.

[0140] like Figures 19 to 22As shown, the second electrical connector 7 includes a lower base 71 and a lower connector 72 disposed on the lower base 71. The lower base 71 is mounted on the furnace base 6, and the lower connector 72 is plugged into and detached from the upper connector 42. The lower base 71 also has a contact assembly, which includes two conductive contacts 73. Each conductive contact 73 corresponds to a probe pin 43. Both the lower connector 72 and the conductive contacts 73 are electrically connected to the control module. When the first electrical connector 4 and the second electrical connector 7 are plugged into or detached, the conductive contacts 73 abut against the corresponding probe pins 43, thereby enabling communication between the thick-film circuit 2 and the thermocouple 8 and the control module.

[0141] To improve the insertion and removal stability and reliability of the first electrical connector 4 and the second electrical connector 7, in one embodiment, the lower seat 71 has an upward-facing insertion positioning groove 7113, and the upper seat 41 is inserted into the insertion positioning groove 7113. Thus, the upper seat 41 and the insertion positioning groove 7113 achieve positioning and guidance during the assembly of the first electrical connector 4 and the second electrical connector 7, ensuring the assembly accuracy of the first electrical connector 4 and the second electrical connector 7. Specifically, the bottom of the recessed portion 4113 of the upper seat 41 abuts against the bottom of the insertion positioning groove 7113, and the seat side portion 4112 engages with the peripheral wall of the insertion positioning groove 7113.

[0142] The furnace base 6 includes a side frame 62, a base plate 63 connected to the upper ends of the side frame 62, and a base plate 63 connected to the lower side of the side frame 62. The side frame 62, base plate 63, and top plate 61 together form a mounting cavity, in which the control module is housed. A second electrical connector 7 is mounted on the top plate 61 with its lower end inserted into the mounting cavity. The side frame 62, top plate 61, and top plate 61 are detachably connected to reduce the processing difficulty of the furnace base 6, and each part can be made of different materials, improving the flexibility of furnace base 6 processing and material selection. Furthermore, a handle 65 is connected to the side frame 62.

[0143] To improve the ease of installation of the lower seat 71, in one embodiment, the lower seat 71 includes a lower main seat portion 711 and a positioning flange portion 712 protruding from the circumferential sidewall of the lower main seat portion 711. The lower end of the lower main seat portion 711 is located below the seat top plate 61 and the upper end is located above the seat positioning plate. The lower main seat portion 711 has the aforementioned insertion positioning groove 7113. The positioning flange portion 712 abuts against the lower side surface of the seat top plate 61 to achieve the installation and positioning of the lower seat 71 on the seat top plate 61. The seat top plate 61 and the lower seat 71 are fastened by a connector passing through the positioning flange portion 712 and the seat top plate 61. The connector is preferably, but not limited to, screws.

[0144] The lower main seat portion 711 includes a main body plate portion 7111 and a side plate portion 7112. The side plate portion 7112 surrounds the periphery of the main body plate portion 7111 so that the two together form an insertion positioning groove 7113. The lower connector 72 is mounted on the main body plate portion 7111. In one embodiment, a mounting through hole is provided on the lower seat body 71, and the lower connector 72 passes through the mounting through hole so that the lower connector 72 extends into the insertion positioning groove 7113, and the lower end of the lower connector 72 is located on the lower side of the lower seat body 71 and is fastened to the lower seat body 71.

[0145] The lower connector 72 is detachably connected to the lower base body 71 to improve the ease of replacement and maintenance of the lower connector 72. Specifically, a fastening post 715 protrudes from the lower side of the lower base plate 31, and a fixing ear plate protrudes from the lower end of the lower connector 72. The fixing ear plate and the fastening post 715 are fastened together by fasteners passing through both. One fastening post 715 is provided on each of the opposite sides of the lower base body 71 to improve the connection stability of the lower connector 72.

[0146] The lower connector 72 includes a lower socket 721 mounted on the lower base 71. The lower socket 721 has multiple insertion holes 7211, each penetrating the upper end of the lower socket 721. Each insertion hole 7211 corresponds to a conductive pin 422, and a conductive insert 722 is disposed within each insertion hole 7211. When the first electrical connector 4 and the second electrical connector 7 are inserted into their respective positions, the conductive pins 422 are inserted into the corresponding insertion holes 7211 and abut against the conductive inserts 722. The specific structure of the lower connector 72 can be referenced from existing technology; this is not the focus of this invention and will not be described further here.

[0147] In one embodiment, the second electrical connector 7 further includes an adapter plate 74, which is mounted on the lower seat 71 and located inside the furnace base 6. The adapter plate 74 is configured to correspond one-to-one with the contact groups. Two conductive contacts 73 of the same contact group are electrically connected to the adapter plate 74. The adapter plate 74 is communicatively connected to the control module, thereby facilitating the connection between the conductive contacts 73 and the control module. Specifically, the adapter plate 74 is detachably mounted on the bottom of the lower seat 71, and the conductive contacts 73 vertically pass through the lower seat 71. The upper end of the conductive contact 73 is connected to the probe pin 43, and the lower end of the conductive contact 73 is welded to the adapter plate 74. The adapter plate 74 is provided with electrical terminals 77 for connection to the control module.

[0148] To improve the ease of installation of the adapter plate 74, a mounting boss 713 protrudes from the lower side of the lower main seat 711. The mounting boss 713 corresponds to the adapter plate 74, and the adapter plate 74 can be detachably installed on the mounting boss 713. Furthermore, the adapter plate 74 and the mounting boss 713 are fastened with screws to ensure a stable connection.

[0149] To improve the safety of the second electrical connector 7, in one embodiment, the second electrical connector 7 further includes a temperature probe 75. The temperature probe 75 is mounted on the lower seat 71 and electrically connected to the adapter plate 74. The temperature probe 75 is used to detect the temperature of the lower seat 71 to prevent it from melting due to excessive temperature. The temperature probe 75 passes through the adapter plate 74 and the lower seat 71 to improve temperature measurement accuracy and ease of installation. Preferably, the temperature probe 75 is arranged in a one-to-one correspondence with the adapter plate 74 to achieve multi-point detection of the lower seat 71 and improve protection safety.

[0150] To improve the ease of installation of the temperature probe 75, a fixing plate 76 is provided on the temperature probe 75, and a protruding post 714 is provided on the mounting boss 713, which is detachably connected to the fixing plate 76.

[0151] Other structures of the electric grill can be set with reference to existing technologies, and this utility model does not limit or elaborate on them.

[0153] This embodiment provides a baking pan and a stove base 6 containing the baking pan. The electric grilling device provided in this embodiment has the same basic structure as the electric grilling device provided in the above embodiments, except that the structure of the second electrical connector 7 is different. This embodiment will not repeat the contents that are the same as those in other embodiments.

[0154] like Figures 23 to 27 As shown, in this embodiment, the electric grilling device also includes a waterproof component 9, which is connected to the upper seat 41 or the lower connector 72. The waterproof component 9 selectively seals the upper opening of the socket 7211. This seal prevents oil or cleaning water from entering the socket 7211 during cleaning of the stove base 6, thus preventing malfunction of the lower connector 72. This improves the ease of cleaning the stove base 6 while ensuring the safety and reliability of the second electrical connector 7. At the same time, when the grill pan is not placed on the stove base 6, the sealing of the upper end of the socket 7211 by the waterproof component 9 can prevent foreign objects from entering the socket 7211, improving the reliability of the lower connector 72.

[0155] In this embodiment, the lower base 71 has a protruding insertion boss 716, which has a downward-facing mounting cavity in which the lower connector 72 is installed. The upper end of the insertion boss 716 has an insertion port 7161 corresponding to each socket 7211, and the insertion ports 7161 and sockets 7211 are aligned vertically. After the baking tray is installed, the insertion boss 716 is inserted into the insertion groove of the upper connector 42. The conductive pin 422 passes through the insertion port 7161 and is inserted into the corresponding socket 7211, contacting the conductive tab 722 in the socket 7211, thereby achieving electrical connection between the upper connector 42 and the lower connector 72.

[0156] In other embodiments, the lower base 71 has an installation through hole, the lower connector 72 is inserted into the installation through hole, and the waterproof component 9 is directly installed on the lower connector 72 and seals the upper end of the insertion hole 7211.

[0157] In this embodiment, the waterproof component 9 includes multiple membrane sealing portions 91, each corresponding to an insertion port 7161, and the membrane sealing portion 91 blocks the corresponding insertion port 7161. A slit is cut into the membrane sealing portion 91, which closes when no external force is applied, thus blocking the insertion port 7161. The slit can be opened by the downward pressure of the conductive pin 422, allowing the conductive pin 422 to pass through the membrane sealing portion 91 and be inserted into the insertion hole 7211. This structural design of the waterproof component 9 enables automatic sealing of the insertion port 7161 when the baking tray is detached from the oven base 6, and does not hinder the insertion of the conductive pin 422 into the insertion hole 7211 during baking tray assembly. The structure is simple and easy to install.

[0158] Specifically, the waterproof component 9 includes an installation body 92, which is inserted into the top of the installation cavity and abuts against the top wall of the cavity. All membrane sealing parts 91 are disposed on the installation body 92, thereby improving the ease of installation and assembly of the waterproof component 9. The thickness of the installation body 92 is greater than the thickness of the membrane sealing parts 91, so as to ensure the installation stability of the installation body 92 in the installation cavity while ensuring the deformation performance of the membrane sealing parts 91.

[0159] Furthermore, the mounting body 92 has multiple through holes that penetrate the lower side of the membrane sealing part 91. Each through hole corresponds to one of the membrane sealing parts 91, and the membrane sealing part 91 is located at the upper end of the through holes. When the slit is squeezed open, it connects with the through holes, allowing the conductive pin 422 to pass through the slit and through holes sequentially before entering the insertion hole 7211. The slit is preferably a cross-shaped slit to ensure the sealing performance of the membrane sealing part 91 when it is not squeezed open. The slit can also be a straight slit or a star-shaped slit, etc.

[0160] The insertion port 7161 includes a first opening and a second opening. The first opening is coaxially connected to the upper side of the second opening. The first opening is circular, and the second opening is tapered, wider at the bottom than at the top. The waterproof component 9 also includes a conical ring 93 connecting the mounting body 92 and the membrane sealing part 91. The membrane sealing part 91 is disposed in the first opening, and the conical ring 93 is disposed in the second opening. The shape of the conical ring 93 is adapted to the shape of the second opening, thereby improving the installation stability of the waterproof component 9.

[0161] In one embodiment, the lower seat 71 is provided with a plurality of drainage holes 719, and the furnace base 6 is provided with a drainage channel, wherein the drainage holes 719 are connected to the drainage through hole. By providing drainage holes 719, water or oil stains accumulated in the upper seat 41 can be discharged through the drainage holes 719, avoiding water accumulation in the insertion positioning groove 7113 and ensuring the normal, reliable and practical use of the second electrical connector 7.

[0162] For example, two sets of drain holes 719 are provided, each set including multiple drain holes 719. The two sets of drain holes 719 are located on opposite sides of the lower connector 72 to improve drainage smoothness. Along the length of the second electrical connector 7, each set of drain holes 719 is located between the lower connector 72 and the corresponding adapter plate 74 to prevent water or oil from flowing to the adapter plate 74.

[0163] Other structures of the electric grilling device in this embodiment can be specifically configured with reference to the above embodiments, and will not be repeated here.

[0164] Example 3

[0165] This embodiment provides an electric grilling device, and the electric grilling device provided in this embodiment has a basically the same structure as that in the above embodiments, with only some differences in settings. This embodiment will not describe the same structure as that in the above embodiments again.

[0166] like Figures 28 to 30 As shown, in this embodiment, the waterproof component 9 is a waterproof cover. The waterproof cover is detachably installed on the outside of the lower connector 72 to seal the upper opening of the socket 7211. When the lower connector 72 needs to be used, the waterproof cover can be removed from the lower connector 72 to enable the use of the upper connector 42. When the furnace base 6 needs to be cleaned, the waterproof cover is installed on the outside of the lower connector 72 to protect the lower connector 72.

[0167] It is worth noting that, in the assembly structure of the lower connector 72 and the lower base 71 in Embodiment 1, the insertion end of the lower connector 72 is exposed relative to the lower base 71, and the waterproof cover is directly covered on the upper end of the lower connector 72; in the assembly structure of the lower connector 72 and the lower base 71 in Embodiment 4, the lower connector 72 is located inside the insertion boss portion 716, and the waterproof cover is covered on the outside of the insertion boss portion 716.

[0168] To prevent the waterproof cover from being lost, the lower base 71 is recessed to form a receiving recess 717. The recessed space of the receiving recess 717 forms a receiving groove 718. The waterproof cover can be detachably placed in the receiving groove 718. This allows the waterproof cover to be stored in the receiving groove 718 when the electric grill is needed, preventing loss or damage due to careless placement and improving the convenience of using the waterproof cover. In other embodiments, a receiving structure can also be provided on the stove base 6 to accommodate the waterproof cover.

[0169] The receiving groove 718 includes a guide groove 7181 and a limiting groove 7182 that are connected vertically. One side wall of the guide groove 7181 extends obliquely from bottom to top away from the other and opposite side wall of the groove. The lower end of the waterproof cover is limited in the limiting groove 7182 and the upper end is received in the guide groove 7181. The guide groove 7181 can guide the waterproof component 9 into the receiving groove 718 and facilitates the removal of the waterproof cover from the receiving groove 718. The limiting groove 7182 can limit the shaking of the waterproof component 9 in the receiving groove 718, thereby improving the stability and reliability of the waterproof component 9 in the receiving groove 718.

[0170] In other embodiments, the shape of the receiving groove 718 can be adapted to the shape of the waterproof cover, and a flip handle or other gripping structure can be provided at the upper end of the waterproof cover to enable the waterproof cover to be placed or removed in the receiving groove 718.

[0171] Along the length of the second electrical connector 7, the waterproof cover is located between the upper connector 42 and the adapter plate 74 to make reasonable use of the installation space on the upper base 41, thereby improving the structural compactness and layout rationality.

[0172] Furthermore, the bottom of the receiving groove 718 is provided with a drain hole 719 to prevent water or oil from accumulating inside the receiving groove 718.

[0173] Other structures of the electric grilling device in this embodiment can be specifically configured with reference to the above embodiments, and will not be repeated here.

[0174] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0175] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
