Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a baking pan and oven. Background Technology

[0002] An oven is a device used to bake food. It is widely used in home or outdoor baking scenarios. Ovens can be divided into electric ovens and gas ovens, depending on their heat source.

[0003] The prior art describes an oven that includes a baking tray and a base. The baking tray has two heating zones arranged side by side. The baking tray has a heating circuit inside each heating zone, and the heating circuit includes multiple heating devices arranged in series. A first electrical connector is provided on one side of the baking tray, and a controller is provided inside the oven base, with a second electrical connector on one side. Both heating circuits are electrically connected to the first electrical connector, and the second electrical connector is electrically connected to both the first electrical connector and the controller.

[0004] Existing ovens, by setting up two heating zones, can achieve zoned cooking. However, because the first electrical connector is located on one side of the baking pan, the wiring connecting the heating circuit on the side furthest from the first electrical connector is longer, increasing the cost of laying the heating circuit. Simultaneously, since the area where the first electrical connector is located cannot accommodate the heating circuit, a relatively cold heating zone forms on the upper side of the baking pan corresponding to the first electrical connector. Therefore, when using the heating zone near the first electrical connector alone, the large proportion occupied by the cold heating zone affects the cooking experience. Furthermore, to increase the temperature of the cold heating zone, the heating power of the heating element near the first electrical connector needs to be increased, expanding the heat radiation area of ​​the heating element to the cold heating zone. This can lead to localized high temperatures directly opposite the higher-power heating element, affecting the overall heating uniformity and placing higher demands on the high-temperature resistance of the first electrical heating element, further increasing the cost of installing the first electrical connector. Utility Model Content

[0005] One of the technical problems solved by this utility model is to provide a baking pan that can effectively solve the problem that existing baking pans with zoned cooking have an excessively large cold zone in one heating zone and poor heating uniformity.

[0006] The second technical problem solved by this utility model is to provide an oven that can effectively solve the problem of poor heating uniformity in existing ovens.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] A baking pan includes a pan body, a heat insulation cover, an electric heating structure, and a first electrical connector. The heat insulation cover is disposed on the back side of the pan body. The pan body has two heating zones arranged side by side along its length. The electric heating structure is disposed on the back side of the pan body corresponding to each of the heating zones. The electric heating structure is located between the pan body and the heat insulation cover.

[0009] The first electrical connector is installed on the back side of the plate and located between the two heating zones. The electrothermal structures of the two heating zones are electrically connected to the first electrical connector. The first electrical connector extends out of the heat insulation cover and is connected to the heat insulation cover. The first electrical connector is used to detachably connect to the second electrical connector on the oven base.

[0010] Compared with the prior art, the baking pan described in this utility model has the following advantages:

[0011] By placing the first electrical connector between the two heating zones, the heating and cooling zones formed by the first electrical connector on the plate surface are distributed between the two heating zones. When using one heating zone alone, the proportion occupied by the heating and cooling zone is small, thus having less impact on cooking. Because the proportion occupied by the heating and cooling zone is reduced, the heating structure can achieve coverage of the heating and cooling zones with a relatively small power, reducing the heating power requirements of the heating structure located near the first electrical connector, reducing the probability of local high temperatures, improving the overall heating uniformity of the heating zone, and reducing the high temperature resistance requirements of the first electrical connector. At the same time, placing the first electrical connector between the two heating zones results in shorter wiring between the two heating structures and the first electrical connector, which facilitates the electrical connection between the heating structures and the first electrical connector.

[0012] By installing a heat insulation cover at the bottom of the baking pan, with the heating element located between the heat insulation cover and the pan, water, oil, or other impurities are prevented from acting on the heating element, thus protecting it, improving its reliability, and facilitating cleaning and maintenance of the baking pan. Simultaneously, the heat insulation cover provides better support for the pan, enhancing its overall structural strength and rigidity, reducing the probability of heat deformation, and minimizing heat transfer to the oven base. This prevents heat buildup at the oven base, avoiding the risk of burns and improving the ease of handling the baking pan.

[0013] A first electrical connector is provided on the baking tray for detachable connection with a second electrical connector to the oven base. The first electrical connector extends through and connects to the heat insulation cover, allowing the first electrical connector, the heat insulation cover, and the tray body to connect to form a more stable overall structure. This ensures the stability and reliability of the first electrical connector while improving the overall disassembly and assembly performance of the baking tray, thus facilitating cleaning and storage. It also effectively prevents the disassembly and assembly of the first and second electrical connectors from affecting the structural stability of the first electrical connector installation location, thereby improving the reliability of the baking tray.

[0014] In one embodiment, the first electrical connector includes an upper body and an upper connector, the upper body extending along the width direction of the baking pan, the upper connector being mounted at the middle of the upper body along the extending direction, and both terminals of each of the heating structures being electrically connected to the upper connector.

The heating circuit includes a plurality of heating devices electrically connected in series, and the heat radiation area of ​​the heating circuit covers the corresponding heating area.

[0021] The thick film circuit has a clearance hole corresponding to the thermocouple, and the thermocouple passes through the clearance hole and is fastened to the disk body.

[0022] In one embodiment, the thermocouple is welded, plugged in, or bonded to the disc body, and the clearance hole is filled with high-temperature resistant sealant.

[0023] In one embodiment, the electrothermal structure includes a thick-film circuit, which includes a first insulating layer, a heating circuit, and a second insulating layer sequentially laid on the back side of the disk. The heating circuit includes a plurality of heating devices electrically connected in series, and the heat radiation area of ​​the heating circuit covers the corresponding heating area. The first insulating layers of the two thick-film circuits are integrally formed.

[0024] In one embodiment, a rib group is provided on the upper side of the disc body for each heating zone, and each rib group includes a plurality of rib portions spaced apart, with the first electrical connector located between two rib groups.

[0025] In one embodiment, each of the rib groups includes a plurality of rib portions spaced apart along the width direction of the disc body, and each rib portion extends along the length direction of the disc body.

[0026] In one embodiment, the heat insulation cover is provided with a mounting boss that protrudes downward, and the height of the mounting boss protruding from the lower surface of the heat insulation cover is greater than or equal to the height of the first electrical connector protruding from the lower surface of the heat insulation cover. The mounting boss is provided on both opposite sides of the baking tray along the length direction and / or on both opposite sides of the baking tray along the width direction.

[0027] The second technical problem mentioned above is solved by the following technical solution:

[0028] An oven includes an oven base and a baking tray as described above. The oven base is provided with a power control unit, and the power control unit is provided with a second electrical connector. The first electrical connector and the second electrical connector are detachably electrically connected.

[0029] Compared with the prior art, the oven described in this utility model has the following advantages: by using the above-mentioned baking pan, the heating uniformity of the oven can be improved, and the performance of the oven can be enhanced.

[0073] Example 1

[0074] This embodiment provides an oven that can bake food while enhancing the food cooking experience and improving the overall performance of the oven.

[0075] like Figures 1 to 4 As shown, the oven includes a base 6, a baking tray, and a control module. The baking tray is detachably installed 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 baking tray to heat the food-bearing surface, thereby heating the food on the food-bearing surface. The control module is installed inside the base 6 and electrically connected to the electric heating structure. The control module is used to control the operation of the oven.

[0076] The baking pan includes a pan body 1, a heat insulation cover 3, and a first electrical connector 4. The upper side of the pan body 1 has a food-bearing surface, and the heat insulation cover 3 covers the back of the pan body 1. The pan body 1 has two heating zones arranged side-by-side along its length. Each heating zone has a corresponding heating structure on the back of the pan body 1, located between the pan body 1 and the heat insulation cover 3. The first electrical connector 4 is installed on the back of the pan body 1 and located between the two heating zones. The heating structures of both heating zones are electrically connected to the first electrical connector 4, which extends beyond the heat insulation cover 3. The control module includes a power control unit, which has a second electrical connector 7 located at the center of the oven base 6 along its length. The first electrical connector 4 and the second electrical connector 7 are detachably electrically connected, and the second electrical connector 7 is electrically connected to the control module.

[0077] The baking pan provided in this embodiment features a heat insulation cover 3 at the bottom of the pan body 1, with the heating structure located between the heat insulation cover 3 and the pan body 1. This design prevents water, oil, or other impurities from affecting the heating structure, thus protecting it, improving its reliability, and facilitating cleaning and maintenance. Simultaneously, the heat insulation cover 3 provides better support for the pan body 1, enhancing its overall structural strength and rigidity, reducing the probability of heat deformation, and minimizing heat transfer to the stove base 6. This prevents heat buildup at the stove base 6, reducing the risk of burns and improving the user's ease of handling the baking pan. The baking tray offers convenience; furthermore, a first electrical connector 4 is provided on the baking tray for detachable connection with the second electrical connector 7 of the oven base 6. The first electrical connector 4 extends through the heat insulation cover 3 and connects to the heat insulation cover 3, allowing the first electrical connector 4, the heat insulation cover 3, and the tray body 1 to connect with each other to form a more structurally stable overall structure. This ensures the stability and reliability of the first electrical connector 4 while improving the overall disassembly and assembly performance of the baking tray, thereby facilitating the cleaning and storage of the baking tray. It also effectively prevents the disassembly and assembly of the first electrical connector 4 and the second electrical connector 7 from affecting the structural stability of the installation location of the first electrical connector 4, thus improving the reliability of the baking tray.

[0078] By placing the first electrical connector 4 between the two heating zones, the heating and cooling zones formed by the first electrical connector 4 on the surface of the plate 1 are dispersed into the two heating zones. When using one heating zone alone, the proportion occupied by the heating and cooling zone is small, thus having less impact on cooking. Since the proportion occupied by the heating and cooling zone is reduced, the heating structure can achieve coverage of the heating and cooling zones with relatively low power, reducing the heating power requirements of the heating structure located near the first electrical connector 4, reducing the probability of local high temperatures, improving the overall heating uniformity of the heating zone, and reducing the high temperature resistance requirements of the first electrical connector 4. At the same time, placing the first electrical connector 4 between the two heating zones results in shorter wiring between the two heating structures and the first electrical connector 4, which facilitates the electrical connection between the heating structures and the first electrical connector 4.

[0079] Handles 65 are provided on opposite sides along the length of the oven base 6 to facilitate the user's movement of the oven. Specifically, the handles 65 are U-shaped to facilitate the user's grip and improve the reliability of moving the oven base 6. The U-shaped structure is preferably an flared U-shape to increase the size of the handles 65, making it more suitable for users with larger hands to move the oven. Support legs 66 are provided at the bottom of the oven base 6 to facilitate the placement of the oven base 6.

[0080] A hinge seat 64 is provided on the rear side of the oven base 6. The oven also includes an oven lid 20, which is hinged to the oven base 6 via the hinge seat 64. This allows the oven lid 20 to rotate and snap onto the upper end of the oven base 6 to form a cooking cavity, facilitating steaming and other cooking operations. The oven lid 20 can also be flipped open relative to the oven base 6 to expose a baking pan for grilling and other cooking operations. The specific structure of the oven lid 20 and the connection structure between the oven lid 20 and the oven base 6 can be designed with reference to existing technology, which is not the focus of this utility model and will not be described in detail here.

[0081] In one embodiment, the pan body 1 and the heat insulation cover 3 form a closed mounting cavity. The heating structure is located inside the mounting cavity and is attached to the back of the pan body 1, spaced apart from the heat insulation cover 3. The close attachment of the heating structure to the pan body 1 shortens the distance between them, thereby enhancing heat conduction from the heating structure to the pan body 1 and improving heating efficiency. Furthermore, the spaced arrangement between the heating structure and the heat insulation cover 3 creates a heat insulation cavity, which reduces the transfer of heat from the heating structure to the heat insulation cover 3, thus reducing downward radiation of heat from the heating structure, minimizing heat loss, lowering the temperature of the heat insulation cover 3, and improving the ease of use of the baking pan.

[0082] 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, by providing a heat-reflective layer, the heat energy radiated to the heat insulation cover 3 can be reflected in the direction towards the plate 1, preventing the heat insulation cover 3 from heating up. At the same time, it can also improve the heating effect of the electric heating structure on the plate 1 and improve the heat energy utilization rate.

[0083] In other embodiments, a heat insulation structure is also provided in the heat insulation 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 may be, but is not limited to, heat insulation cotton, heat insulation coating or other structures that can reduce heat conduction.

[0084] The distance between the heating element and the heat insulation cover 3 is preferably 0.8mm to 2mm to ensure heat insulation while reducing the overall thickness of the baking pan and improving the user experience. The distance between the heating element and the heat insulation cover 3 can be, but is not limited to, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, and 2mm. It is understood that the distance between the heating element and the heat insulation cover 3 can be specifically determined based on the power of the heating element.

[0085] In one embodiment, the electrothermal structure includes a thick-film circuit 2. The thick-film circuit 2 has multiple heating elements 21 dispersed at the bottom of the plate body 1. Each heating element 21 can generate heat after being energized, and the heat generated by each heating element 21 radiates upward and covers part of the food-bearing surface, so that the heat radiation area formed by all the heating elements 21 in the thick-film circuit 2 can cover the corresponding heating area, thereby improving the heating uniformity of the food-bearing surface by the electrothermal structure. Specifically, the thick-film circuit 2 includes a first insulating layer, a heating circuit, and a second insulating layer sequentially laid on the back side of the plate body 1. Each thick-film circuit 2 is provided with at least one heating circuit, and each heating circuit includes multiple heating elements 21 electrically connected in series. The heat radiation area of ​​the heating circuit covers the corresponding heating area.

[0086] By configuring the heating structure as a thick-film circuit 2, it is advantageous to set up multiple discrete heating devices 21, thereby improving the heating uniformity of the food-bearing surface. Simultaneously, using a thick-film circuit 2 as the heating structure reduces the footprint of the heating structure, improves the overall compactness of the baking pan, and reduces the size and weight of the baking pan. In other embodiments, the heating structure can be a heating wire laid on the bottom of the pan body 1, a heating tube installed on the bottom of the pan body 1, or other types of heating structures.

[0087] The first insulating layer is disposed between the heating circuit and the pan body 1 to prevent leakage of current in the heating circuit from causing the pan body 1 to become electrified. The second insulating layer can prevent leakage of current in the heating circuit from causing the heat insulation cover 3 to become electrified, thus improving the safety of the baking pan. The heating devices 21 on the same heating circuit are connected in series so that all heating devices 21 have the same current, ensuring the consistency of heating power of the heating devices 21 and improving heating uniformity. At the same time, it can reduce the voltage acting on a single heating device 21, ensuring the operational safety and reliability of the heating device 21. Because the distance between the heating circuit and the pan body 1 is small, the risk of electrical breakdown is relatively high. Therefore, multiple layers of the first insulating layer need to be disposed between the heating circuit and the pan body 1 to increase the thickness of the insulation structure between the heating circuit and the pan body 1, thereby reducing the probability of electrical breakdown of the heating device 21 on the side facing the pan body 1, reducing the probability of leakage of current in the pan body 1, and ensuring the safety of the baking pan.

[0088] Since the heating circuit is relatively close to the disc 1 and relatively far from the heat insulation cover 3, the first insulating layer has more layers than the second insulating layer, meaning the thickness of the first insulating layer is greater than the thickness of the second insulating layer. This is to prevent the thick-film circuit 2 from being electrically broken down while reducing the cost of the thick-film circuit 2. Preferably, the first insulating layer has 3 to 5 layers, and the second insulating layer has 1 to 3 layers. However, it is understood that the number or thickness of the first and second insulating layers can be specifically set according to the electrical breakdown parameters of the thick-film circuit 2.

[0089] 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 existing technology. This embodiment does not limit or elaborate on this.

[0090] In one embodiment, the first insulating layers of the two thick film circuits 2 are integrally formed, that is, the first insulating layers of the two thick film circuits 2 cover the mounting area of ​​the first electrical connector 4, and the heating circuits of the two thick film circuits 2 are respectively located on opposite sides of the first electrical connector 4 to avoid interference between the first electrical connector 4 and the heating circuit.

[0091] In one embodiment, the power control unit can supply power to the thick film circuit 2 separately to achieve separate control of the two thick film circuits 2. This enables individual heating of each heating zone, realizes zoned cooking, improves the cooking experience, and helps reduce energy consumption and save costs when a larger heating zone is not needed.

[0092] To reduce control costs, in one embodiment, each thick-film circuit 2 includes a heating circuit. In other embodiments, each heating zone may be provided with multiple heating circuits, and the heat radiation areas of the multiple heating circuits at least partially overlap. The control module can control the multiple heating circuits 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.

[0093] The heating elements 21 on the same heating circuit are distributed in a serpentine pattern to ensure the distribution density of the heating elements 21 while improving the ease of connection between them. For example, the heating circuit includes multiple heating groups spaced apart along the width direction of the disk 1. Each heating group includes multiple heating elements 21 spaced apart along the length direction of the disk 1. The heating elements 21 of the multiple heating groups are connected in series to form a serpentine structure. This arrangement of the heating elements 21 is relatively regular, which facilitates determining the local arrangement of the heating elements 21 based on the size of the heating area and the power of the heating elements 21.

[0094] It is worth noting that the heating device 21 in the heating circuit can also adopt other layout methods, as long as the heating power of all heating devices 21 in the heating circuit meets the cooking requirements and the heating radiation area basically covers the corresponding heating area.

[0095] Furthermore, for two adjacent heating groups whose connection positions are close to the left and right edges of the plate body 1, a heating device 21 is provided between the ends of the two heating groups that are close to the edge of the plate body 1, so as to avoid local low temperature areas at the edge of the plate body 1 and further improve the heating uniformity of the heating area.

[0096] In one embodiment, the heating devices 21 of two adjacent heating groups are staggered in the length direction, thereby reducing the overlapping area of ​​the heat radiation range of the heating devices 21 of the two adjacent heating groups, ensuring that multiple heating devices 21 cover different areas, and improving the uniformity of heating temperature in different areas of the heating zone.

[0097] In the same heating group, there is a distance d1 between two adjacent heating elements 21, and a distance d2 between two adjacent heating groups, where d2 ≥ d1. Preferably, 8mm ≤ d1 ≤ 18mm. This avoids the problem of excessively small distances between two adjacent heating elements 21, resulting in large heat radiation areas and localized high-temperature points, thus wasting heat. It also avoids the problem of excessively large distances between two adjacent heating elements 21, resulting in widely separated heat radiation areas and localized low-temperature points, thus causing uneven heating of the baking pan. d1 can be, but is not limited to, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, and 18mm. More preferably, 10mm ≤ d1 ≤ 15mm.

[0098] It is worth noting that the spacing between two adjacent heating elements 21 is related to the rated power of a single heating element 21. The higher the rated power of a single heating element 21, the larger the heat radiation area it generates. Therefore, when the rated heating power of the baking pan remains constant, the number of heating elements 21 required decreases, and the spacing between two adjacent heating elements 21 increases. The spacing between two adjacent heating elements 21 can be specifically determined based on the rated power of the baking pan, the total area of ​​the heating zone, and the heating power of a single heating element 21.

[0099] For example, the rated power of the baking pan is P0, the area of ​​the heating zone is S, the heating power of a single heating element 21 is P1, and the required number of heating elements 21 is N, where N = P0 / P1. The N heating elements 21 are approximately evenly distributed in the corresponding area of ​​the heating zone, thus obtaining the spacing range between two adjacent heating elements 21.

[0100] like Figures 5 to 7 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 can prevent food from falling out of the support plate portion 11 and prevent oil from flowing out along the edge of the support plate portion 11 during cooking. A thick film circuit 2 is disposed on the lower side surface of the support plate portion 11.

[0101] Furthermore, the support plate 11 has two first sides arranged opposite each other in the width direction and two second sides arranged opposite each other in the length direction. The two first sides are parallel and spaced apart, and the two second sides have an arc-shaped structure. This increases the maximum width of the support plate 11, increases the amount of food it can hold, and also helps to reduce the overall structural size of the oven while ensuring the amount of food it can hold.

[0102] In one embodiment, the upper edge of the surrounding portion 12 is folded outward to form a flanged portion 13, and the flanged portion 13 is folded downward and inward to form a folded edge portion 14. The flanged portion 13 and the folded edge portion 14 enhance the structural strength and rigidity of the pan body 1 at the opening edge, reduce the probability of deformation of the pan body 1, and facilitate the user's handling of the baking pan, thus improving the user experience. Simultaneously, the flanged portion 13 and the folded edge portion 14 facilitate the user's handling of the baking pan.

[0103] Each heating zone on the upper side of the pan body 1 is provided with a set of raised ribs, each set including multiple protruding rib portions 15. The first electrical connector 4 is located between two sets of raised ribs. By setting the raised rib sets, the rib portions 15 can 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 setting of the rib portions 15 can reduce the probability of food sticking to the pan body 1, improving the cooking experience. Furthermore, by setting two sets of raised ribs, the two heating zones can be better visually separated, making it easier for users to identify and use the heating zones, thus improving the cooking experience.

[0104] In one embodiment, each rib group includes a plurality of rib portions 15 spaced apart along the width direction of the plate body 1, and the rib portions 15 extend along the length direction of the plate body 1. This facilitates the placement of food on the rib portions 15 and makes it easier to visually distinguish the heating areas. In other embodiments, the rib group may include a plurality of rib portions 15 spaced apart along the length direction of the plate body 1, the rib portions 15 extend along the width direction, and the spacing between two adjacent rib portions 15 in the same rib group is smaller than the spacing between rib portions 15 in two adjacent rib groups.

[0105] Furthermore, a heating group is provided between two adjacent ribs 15 in the same group and between the rib 15 and the adjacent edge portion 12, so that the heating group can avoid the ribs 15 while further improving the heating uniformity of the baking pan in all places.

[0106] Specifically, the support plate portion 11 is stamped upward to form a raised rib portion 15, which enhances the overall structural strength of the pan body 1. In the width direction of the raised rib portion 15, the height of the raised rib portion 15 protruding from the support plate portion 11 gradually decreases from the middle to both sides of the raised rib portion 15. This facilitates the dripping of oil on the raised rib portion 15 down onto the support plate portion 11, thereby facilitating oil recovery and cleaning of the pan body 1. Simultaneously, this design reduces the probability of food adhering to the pan body 1, preventing food from burning. The cross-section of the raised rib portion 15 can be arc-shaped, triangular, or trapezoidal with a chamfered edge and a smaller top and larger bottom. The height of the raised rib portion 15 protruding from the support plate portion 11 is preferably 0.5mm to 2mm. The height of the protruding rib 15 from the support plate 11 can be, but is not limited to, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm, etc.

[0107] 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 32 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 fitted 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.

[0108] 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. Simultaneously, a sealing ring is provided at the connection point between the heat insulation cover 3 and the tray 1 to seal the connection.

[0109] In one embodiment, the included angle between the side plate portion 32 and the bottom plate portion 31 is an obtuse angle, thereby allowing the connecting edge portion 33 to be positioned close to the edge of the support plate portion 11 while the lower end of the heat insulation cover 3 tapers inward to reduce the overall footprint of the baking tray. The included angle between the side plate portion 32 and the bottom plate portion 31 is greater than 90° and less than 120°. The heat insulation cover 3 is made of high-temperature resistant materials such as stainless steel or ceramic.

[0110] like Figure 7 and Figure 8As shown, in one embodiment, a thermocouple 10 is provided on the disk body 1, with each thermocouple 10 corresponding to a heating zone. The thermocouple 10 is located within the setting area of ​​the thick-film circuit 2 and is offset from the heating circuit. The thermocouple 10 is used to detect the temperature of the disk body 1, facilitating the control module's control of the thick-film circuit 2. The two terminals of the thermocouple 10 are electrically connected to the first electrical connector 4 to transmit the detection signal to the control module. By placing the thermocouple 10 on the disk body 1, the reliability and stability of the contact between the thermocouple 10 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 10 is offset from the heating device 21 and the conductive component 22.

[0111] To improve the stability of the thermocouple 10 installation, the thermocouple 10 is welded to the back of the disk 1 to ensure reliable contact between the sensing end of the thermocouple 10 and the disk 1, simplifying the installation of the thermocouple 10. Furthermore, a clearance hole is provided on the thick-film circuit 2, and the thermocouple 10 is installed in the clearance hole to avoid interference between the thermocouple 10 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.

[0112] In one embodiment, each heating zone is provided with one thermocouple 10 to reduce costs and simplify the connection between the thermocouple 10 and the first electrical connector 4. The thermocouple 10 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 10.

[0113] like Figure 3 , Figure 4 and Figure 7 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.

[0114] The heat shield 3 has a mounting 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 mounted on the back side of the heat shield 3. The upper connector 42 passes through the mounting port 311 and is electrically connected to the second electrical connector 7. Both heating structures are electrically connected to the upper connector 42. Specifically, both terminals of each thick film circuit 2 are electrically connected to the upper connector 42.

[0115] like Figures 9 to 14As shown, in one embodiment, the upper seat 41 is a long strip structure extending along the width direction of the tray 1. The upper connector 42 is installed in the middle of the upper seat 41 along its extension direction, thereby increasing the working area of ​​the first electrical connector 4 and the second electrical connector 7 that cooperate with it, thus improving the stability and reliability of both when the baking tray and the oven base 6 are assembled. This can effectively avoid the situation where the first electrical connector 4 and the second electrical connector 7 do not make good contact due to the baking tray not being assembled properly. At the same time, setting the upper connector 42 in the middle of the upper seat 41 along its length direction can improve the force balance when the upper connector 42 and the second electrical connector 7 are inserted and removed, thereby improving the stability and safety of insertion and removal.

[0116] The first electrical connector 4 is sealed and installed on the heat insulation cover 3 by the mounting component 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.

[0117] The mounting assembly 5 includes an annular seal 52 and multiple fixing components 51. The fixing components 51 are connected to the back side of the pan body 1 and detachably connected to the upper seat 41. The annular seal 52 is sandwiched between the heat insulation cover 3 and the upper seat 41 and surrounds the mounting opening 311, so that the annular seal 52 seals the mounting gap between the upper seat 41 and the heat insulation cover 3, reducing the probability of water vapor and oil entering the interior of the heat insulation cover 3 through the gap, and improving the safety and reliability of the baking pan. Furthermore, by setting multiple fixing components 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 conducive to avoiding the electronic components on the first electrical connector 4.

[0118] Two of the multiple fixing components 51 are first fixing components 51a. The two first fixing components 51a are set at the two ends of the upper seat 41 and abut against the side of the heat insulation cover 3 facing the pan body 1. The end of the upper seat 41, the heat insulation cover 3 and the fixing components 51 are fastened by the first fasteners that pass through the three, so that the first electrical connector 4, the heat insulation cover 3 and the pan body 1 are connected to form an integral structure, ensuring the overall structural strength and rigidity of the baking pan.

[0119] The remaining fixing components 51 are second fixing components 51b. The upper seat 41 has a seat fixing post 45 protruding from it in the direction towards the disc body 1. The second fixing components 51b and seat fixing posts 45 are arranged in a one-to-one correspondence, and are fastened to each other by second fasteners passing through them. This prevents the upper connector 42 from shaking when it is inserted or removed from the second electrical connector 7 due to a lack of support in the middle area of ​​the upper seat 41, thus improving the structural stability and reliability of the first electrical connector 4. At least one second fixing component 51b is provided on each of the opposite sides of the upper connector 42 to ensure that the upper connector 42 does not shake during insertion or removal.

[0120] It is worth noting that in other embodiments, multiple fixing components 51 may be provided at circumferential intervals along the annular seal 52.

[0121] In one embodiment, the first fastener passes through the annular seal 52, thereby facilitating the pressing of the annular seal 52 between the heat shield 3 and the upper seat 41, and effectively preventing the annular seal 52 from loosening relative to the upper seat 41. The annular seal 52 is made of a high-temperature resistant material such as rubber or silicone.

[0122] The projection of the fixing component 51 on the disk body 1 is misaligned with the heating circuit. 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.

[0123] 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.

[0124] The upper seat 41 includes an upper main seat portion 411. Both ends of the upper main seat portion 411 protrude outwards and are provided with fixing ears 412. The fixing ears 412 are vertically aligned with the first fixing component 51a. A seat fixing post 45 protrudes from the upper main seat portion 411. The two ends of the annular seal 52 are sandwiched between the fixing ears 412 and the heat insulation cover 3. The fixing ears 412, the annular seal 52, the heat insulation cover 3, and the first fixing component 51a are fastened together by a first fastener passing through them.

[0125] 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.

[0126] 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. 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.

[0127] The mounting assembly 5 also includes a heat-insulating support 53, which is sandwiched between the disc body 1 and the heat insulation cover 3. The heat-insulating support 53 supports the heat insulation cover 3, reducing the probability of deformation due to heat or other reasons, and improving the structural stability of the heat insulation cover 3 at the installation position of the first electrical connector 4. This improves the installation accuracy of the first electrical connector 4, thereby ensuring the stability and reliability of the plug-in connection between the first electrical connector 4 and the second electrical connector 7. The heat-insulating support 53 is preferably made of materials with heat insulation and support properties, such as ceramics.

[0128] 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.

[0129] 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.

[0130] 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. The lower ends of the outer sealing ring portion 5212 and the inner sealing ring portion 5211 are connected by a connecting ring. The outer sealing ring portion 5212 is sandwiched between the main upper seat 41 and the heat insulation cover 3, and 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] like Figure 11 , Figures 14 to 17 As shown, the bottom of the recessed groove is recessed in the 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.

[0135] 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. The two terminals of the heating circuit are respectively connected to the two heating pins 422a of the same power supply pin group.

[0136] In one embodiment, two probe connection assemblies are also installed on the upper body 41. Each probe connection assembly corresponds to a thermocouple 10. Each probe connection assembly includes two probe pins 43. The two terminals of the thermocouple 10 are connected to the two probe pins 43 to connect the thermocouple 10 to the detection circuit. By integrating the upper connector 42 and the probe pins 43 onto the upper body 41, the integration of the first electrical connector 4 can be improved, its size reduced, and its footprint decreased.

[0137] The two probe electrical connection groups are located on opposite sides of the upper connector 42 along the length direction. This arrangement helps to reduce the overall size of the first electrical connector 4, improve the ease of installation of the first electrical connector 4 on the disk body 1, and reduce the footprint. At the same time, it facilitates the connection between the two heating circuits and the two thermocouples 10 and the first electrical connector 4, reduces wiring interference, and improves wiring convenience.

[0138] 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 electrically connected to a terminal of the heating structure. The live contact 423b is electrically connected to a tab of the thermocouple 10. 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 22 of the heating circuit.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] To improve the safety of the thick-film circuit 2, a temperature controller 44 is provided on the upper body 41. The temperature controller 44 is configured one-to-one with the heating zone, and is connected in series between a terminal of the heating structure and the upper connector 42. Specifically, the temperature controller 44 is connected in series between a terminal of the heating circuit and the corresponding conductive pin 422. Thus, by connecting the temperature controller 44 in series to the power supply circuit of the heating circuit, the temperature controller 44 conducts the two heating pins 422a when the temperature is lower than the preset temperature, so that the power supply circuit of the heating circuit is turned on; the temperature controller 44 disconnects when the temperature is equal to or higher than the preset temperature, so that the power supply to the heating circuit is disconnected, preventing the pan 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.

[0143] In this embodiment, two temperature controllers 44 are located on opposite sides of the upper connector 42 along the width direction of the panel 1, and each temperature controller 44 is located between the first electrical connector 4 and the corresponding probe connection group. This ensures sufficient installation space for the temperature controller 44 while reducing interference between the temperature controller 44 and the upper connector 42 and probe connection group, and improves the layout regularity of the electrical components on the first electrical connector 4 on the upper base 41. The temperature controller 44 is preferably a jump-type temperature controller 44 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 described in detail here.

[0144] like Figure 10 and Figure 16As 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.

[0145] 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.

[0146] 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 power 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.

[0147] like Figure 3 and Figure 18 As shown, 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, and the lower part of the baking tray is accommodated in the placement groove 611. Thus, the placement groove 611 enables the baking tray to be installed and positioned 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. The second electrical connector 7 is installed on the groove wall of the placement groove 611 and is detachably connected to the oven base 6 to facilitate the installation, maintenance, and replacement of the second electrical connector 7.

[0148] To further improve the stability of the baking tray on the oven base 6, the heat insulation cover 3 is provided with downward protruding mounting bosses 34. Mounting bosses 34 are also provided on opposite sides of the tray body 1 along its width and / or on opposite sides of its length. The oven base 6 has mounting grooves 612, which correspond one-to-one with the mounting bosses 34. The mounting bosses 34 are inserted into the mounting grooves 612 to further guide the baking tray during installation. The mounting bosses 34 protrude from the heat insulation cover 3, with one at each of the four corners of the heat insulation cover 3 to ensure guiding stability and reliability. Furthermore, the mounting bosses 34 are formed by pressing downwards from the bottom of the heat insulation cover 3 to reduce processing difficulty and improve the overall structural strength and rigidity of the heat insulation cover 3.

[0149] The lower end of the mounting 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 mounting boss 34 first engages with the mounting groove 612 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.

[0150] The mounting boss 34 is preferably a tapered boss that is larger at the top and smaller at the bottom, and the mounting groove 612 is a tapered groove. This allows the mounting boss 34 to gradually tighten its fit when inserted into the mounting groove 612, improving the ease of placing and removing the baking tray and the stability after installation. In one embodiment, two mounting bosses 34 are provided at both ends of each first side, that is, the four mounting bosses 34 are arranged in a rectangular pattern to improve positioning reliability.

[0151] like Figure 19 , Figure 22 and Figure 23 As 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 10 and the control module.

[0152] 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.

[0153] 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.

A second electrical connector 7 is installed on the top plate 61 and its lower end is inserted into the receiving 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 for easy gripping.

[0154] 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 top plate 63. 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.

[0155] The lower main seat portion 711 includes a main body plate portion 7111 and a side edge portion 7112. The side edge 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. 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.

[0156] 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.

[0157] 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 socket 721. Each insertion hole 7211 corresponds to a conductive pin 422, and a conductive insert is disposed within each insertion hole 7211. When the first electrical connector 4 and the second electrical connector 7 are inserted into their respective holes 7211, the conductive pins 422 abut against the conductive inserts. 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] In this embodiment, the oven also includes a waterproof component 9, which is connected to the upper base 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 oven base 6, thus preventing malfunction of the lower connector 72. This improves the ease of cleaning the oven base 6 while ensuring the safety and reliability of the second electrical connector 7. At the same time, when the baking tray is not placed on the oven 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.

[0163] In this embodiment, the waterproof component 9 includes multiple membrane sealing portions 91, each corresponding to an insertion port, and each membrane sealing portion 91 blocks the corresponding insertion port. A slit is cut into the membrane sealing portion 91. The slit closes when no external force is applied, thus blocking the insertion port. 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 insert into the insertion hole 7211. This structural design of the waterproof component 9 enables automatic sealing of the insertion port when the baking tray is removed 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. A cross-shaped slit is preferred to ensure the sealing performance of the membrane sealing portion 91 when it is not squeezed open. A straight slit or a star-shaped slit can also be used.

[0164] like Figure 3 and Figure 20 As shown, to collect waste oil generated during cooking, an oil collection component 8 is installed on the baking pan. The oil collection component 8 includes an oil collection box 81, which is installed on the stove base 6. An upper oil drain channel is provided at one end of the baking pan, with its upper end penetrating the pan body 1 and its lower end penetrating the heat insulation cover 3. A lower oil drain channel is provided on the stove base 6, with its inlet end connected to the outlet end of the upper oil drain channel. The inlet end of the upper oil drain channel is formed on the surface of the pan body 1, and the outlet end of the lower oil drain channel is connected to the oil collection box 81. Thus, the waste oil generated on the baking pan flows sequentially through the upper and lower oil drain channels into the oil collection box 81, achieving waste oil recycling.

[0165] In one embodiment, the upper oil drain channel is selectively opened or closed, so that when the upper oil drain channel is open, the baking pan can be used for frying, grilling and other operations of food, and when the upper oil drain channel is closed, the oven can be used for steaming and other cooking, thereby enabling the baking pan to realize multiple cooking modes and improving the user experience of the oven.

[0166] Specifically, a sealing element is detachably installed at the upper or lower end of the upper oil drain channel. This sealing element blocks the upper oil drain channel, allowing it to be removed when needed to ensure normal oil drainage. Furthermore, the sealing element is detachably installed at the upper end of the upper oil drain channel, thus preventing oil accumulation within the channel when it is blocked. The sealing element can be, but is not limited to, a pipe cap or similar sealing structure.

[0167] The oil collection assembly 8 includes an upper oil discharge pipe 83. An upper oil discharge port is provided on the disc body 1. The upper end of the upper oil discharge pipe 83 is connected to the disc body 1 and located at the upper oil discharge port. The lower end of the upper oil discharge pipe 83 extends out of the heat insulation cover 3. The inner cavity of the upper oil discharge pipe 83 forms an upper oil discharge channel, thereby enabling the discharge of waste oil through the upper oil discharge pipe 83 and facilitating the connection between the upper oil discharge channel and the lower oil discharge channel.

[0168] In one embodiment, the upper oil drain pipe 83 is inserted into the upper oil drain port and welded to the disc body 1 to ensure the stability and reliability of the installation of the upper oil drain pipe 83 on the disc body 1, and to prevent oil from flowing into the mounting cavity through the gap between the upper oil drain pipe 83 and the disc body 1. In other embodiments, the upper oil drain pipe 83 may also be folded outward at its upper end to form a flange structure, and the flange structure is fitted and fastened to the bottom of the disc body 1.

[0169] The heat insulation cover 3 has a pipe perforation, through which the upper oil pipe 83 passes. The periphery of the pipe perforation is folded to form a fitting edge 35, which fits against the outer wall of the pipe perforation to improve the assembly stability and reliability of the heat insulation cover 3 and the upper oil pipe 83.

[0170] The upper end of the furnace base 6 is provided with a lower oil drain port 613, which is directly opposite to the upper oil drain channel. Specifically, the lower oil drain port 613 is provided on the top plate 61 of the base. The oil collection assembly 8 includes a lower oil drain pipe 84, the upper end of which is installed on the top plate 61 of the base and located at the lower oil drain port 613, and the lower end of which is connected to the inner cavity of the oil collection box 81, forming a lower oil drain channel inside the lower oil drain pipe 84.

[0171] The top plate 61 has a partial downward recess to form an oil collecting recess 614. The recessed space of the oil collecting recess 614 forms an oil collecting groove, and the bottom of the oil collecting groove has a lower oil discharge port 613. This allows the oil sludge at the top plate 61 to be collected and guided, ensuring effective oil recovery. The upper end of the lower oil discharge pipe 84 is fitted onto the outside of the oil collecting recess 614 to prevent oil sludge from accumulating at the connection between the lower oil discharge pipe 84 and the top plate 61, ensuring smooth oil discharge and reducing the probability of oil and water leakage. The lower oil discharge pipe 84 is preferably welded to the oil collecting recess 614 to ensure the installation stability and reliability of the lower oil discharge pipe 84. The projection of the lower end of the upper oil discharge channel on the top plate 61 is located within the oil collecting recess 614 to prevent oil from flowing to the upper end of the furnace base 6 due to the baking tray being installed at an angle.

[0172] To improve the convenience of waste oil cleaning, the oil collection box 81 is horizontally pull-out mounted on the furnace base 6, facilitating its placement and removal. Specifically, the furnace base 6 has a mounting box 631 at its bottom, with an open top and side. The oil collection box 81 is pull-out mounted within the mounting box 631, and the lower oil drain pipe 84 is located above the open side of the mounting box 631. The specific structure of the oil collection box 81 and its mounting structure on the furnace base 6 can be based on existing technology, and this utility model does not limit or elaborate on these aspects.

[0173] The upper ends of the mounting box 631 and the oil collection box 81 are open. The furnace base 6 also includes a cover plate 82 that can be detachably installed on the base plate 63. The cover plate 82 blocks the upper end opening of the mounting box 631, and an oil guide port is provided on the cover plate 82. The oil guide port is connected to the lower end of the lower oil pipe 84 and the inner cavity of the oil collection box 81 to reduce the probability of oil in the oil collection box 81 splashing upward into the mounting cavity.

[0174] The cover plate 82 has an upwardly protruding oil guide portion 821. The lower oil discharge channel includes an oil guide channel formed in the oil guide portion 821, thereby increasing the depth of the oil guide channel to further reduce the probability of oil in the oil collection box 81 flying upward through the oil guide port. The cross-sectional area of ​​the oil guide channel gradually decreases from top to bottom to further prevent oil in the oil collection box 81 from splashing upward. The lower end of the lower oil discharge pipe 84 extends into the oil guide channel, thereby helping to prevent waste oil flowing out of the lower oil discharge pipe 84 from flowing to the outside of the oil guide channel.

[0177] like Figure 24 and Figure 25As shown, in this embodiment, a buffer 30 is provided between the bottom of the mounting boss 34 and the bottom of the mounting groove 612, thereby enabling buffering when the baking tray is installed on the oven base 6, reducing impact, and improving safety and reliability.

[0178] In this embodiment, the buffer 30 is detachably installed at the bottom of the mounting groove 612, reducing the probability of the buffer 30 falling off and improving its durability. In other embodiments, the buffer 30 may also be provided on the mounting boss 34.

[0179] To improve the stability of the buffer component 30, the buffer component 30 includes a buffer pad portion 301 and a snap-fit ​​portion 302. The snap-fit ​​portion 302 is provided with an annular groove, and the bottom of the mounting groove 612 has a fixing hole. The edge of the fixing hole is inserted into the annular groove, and the buffer pad portion 301 is disposed at the bottom of the mounting groove 612. When the mounting boss 34 is inserted into the mounting groove 612, the bottom of the mounting boss 34 abuts against the buffer pad portion 301.

[0180] The buffer 30 also includes a guide post 303 connected to the snap-fit ​​portion 302. The cross-sectional area of ​​the snap-fit ​​portion 302 gradually decreases in the direction away from the buffer pad portion 301 to form a frustum structure. The guide post 303 is connected to the small end of the frustum structure and is used to guide the insertion fixing hole, thereby improving the assembly efficiency of the buffer 30.

[0181] Other structures of the oven can be set up with reference to the above embodiments, and will not be described again here.
