Description

Technical Field

[0001] This application relates to the field of cooking utensils technology, and in particular to a multi-zone variable temperature baking plate. Background Technology

[0002] Electric grill plates are a popular type of grilling equipment. Current electric grill plates use bottom heating elements to heat the plate and stop heating once the set temperature is reached. The surface of the grill plate maintains a relatively high temperature regardless of whether food is being heated. When some areas are not being heated, a lot of heat is wasted, increasing the user's electricity costs.

[0003] For example, Chinese utility model patent CN202436903U discloses a novel electric baking pan, which includes a frame, a baking pan, a heating element, and a heating controller. The heating element is cast together with the baking pan as a single component, and the heating element is located on the bottom surface of the baking pan. This patent uses a single baking pan for heating, without a segmented heating structure. Utility Model Content

[0004] The purpose of this application embodiment is to provide a multi-zone variable temperature baking plate, including a baking plate body, the baking plate body comprising:

[0005] The food heating layer has multiple grilling zones for heating food;

[0006] A heating layer is disposed below the food heating layer, and the heating layer includes multiple heating elements corresponding to the multiple grilling zones respectively;

[0007] Multiple temperature probes are respectively disposed between the heating element and the corresponding grilling zone, and connected to the corresponding grilling zone, so as to detect the cooking temperature of each grilling zone.

[0008] A bottom outer shell layer is disposed below the heating layer and is detachably connected to the food heating layer;

[0009] A control module, which is connected to the heating element and the temperature probe respectively, is used to control the opening and closing of the corresponding heating element according to the temperature detected by the temperature probe.

[0010] This application, by setting up multiple independent grilling zones and corresponding heating elements and temperature probes, can accurately control the temperature of different grilling zones individually, greatly improving the flexibility and efficiency of cooking and meeting diverse cooking needs.

[0011] As an optional embodiment, the baking plate body further includes:

[0012] An insulating and heat-conducting layer is disposed between the food heating layer and the heating layer to transfer the heat generated by the heating layer to the food heating layer.

[0013] An insulating layer is disposed between the heating layer and the bottom outer shell layer.

[0014] This application, through the inclusion of an insulating and heat-conducting layer, effectively transfers heat generated by the heating layer to the food heating layer, ensuring proper heating of the food. It also provides insulation, preventing electrical leakage from the heating layer and thus avoiding safety hazards for the user, thereby improving product safety and heat transfer efficiency. The presence of the insulating layer further enhances the insulation performance of the baking plate, providing users with more reliable safety protection, while also helping to reduce heat loss to the bottom outer shell layer, improving energy utilization efficiency.

[0015] As an optional embodiment, the baking plate body further includes a heat insulation layer, which is disposed between the insulating layer and the bottom outer shell layer.

[0016] This application further reduces heat loss by placing the heat insulation layer between the insulation layer and the bottom outer shell layer, allowing more heat from the baking plate to concentrate on the food heating layer, thus improving energy efficiency and reducing energy consumption. At the same time, it also prevents the bottom outer shell layer from overheating, preventing accidental burns to the user and enhancing product safety.

[0017] As an optional embodiment, the baking plate further includes a foot, the upper end of which has a foot insertion interface, and the lower side of the bottom outer shell layer has a baking plate insertion interface. The foot is electrically connected to the baking plate insertion interface through the foot insertion interface.

[0018] This application allows for detachable connection between the base and the baking plate via a foot insertion interface, facilitating the assembly and disassembly of the baking plate, making it easy to transport and store. It also allows for flexible replacement of the base according to actual usage needs.

[0019] As an optional embodiment, the base is provided with a control knob that is electrically connected to the control module. By operating the control knob, the control module can control the power supply to the heating layer.

[0020] This application allows users to conveniently and quickly turn the heating layer on and off at the bottom of the baking plate by setting a control knob on the base that is electrically connected to the control module. This eliminates the need for additional operation buttons on the main body of the baking plate, simplifying the structural design of the baking plate and making it easier for users to operate, thus improving the user experience.

[0021] As an optional embodiment, the base is provided with a power cord socket, which is connected to an external power source.

[0022] The base of this application is equipped with a power cord socket, which makes the connection of the power cord more reasonable and convenient, avoids the inconvenience and safety hazards that may be caused by connecting the power cord to the baking plate body, and also makes the overall appearance of the baking plate more concise and beautiful.

[0023] As an optional embodiment, at least two grilling zones are provided, and the grilling areas of the two grilling zones may be the same or different.

[0024] This application sets up at least two grilling zones, and the grilling areas can be the same or different, which meets the diverse needs of different ingredients and cooking methods for grilling area, and further enriches the possibilities of cooking.

[0025] As an optional embodiment, the area of ​​the heating element is matched with the area of ​​the corresponding grilling area, and the position of the temperature probe corresponds to the center position of the corresponding grilling area.

[0026] The heating element in this application has an area that matches the corresponding grilling area, ensuring even heat distribution within the grilling zone and preventing localized overheating or underheating. This guarantees even heating of the food and improves cooking quality. The temperature probe is positioned to correspond to the center of the grilling zone, enabling more accurate temperature detection and providing more precise data to the control module for more precise temperature control.

[0027] As an optional embodiment, the baking plate body has a curved structure, and the portion of the baking plate body near its center is lower than the portion near its outer periphery.

[0028] The baking plate of this application adopts a curved structure, utilizing the principle of gravity so that the oil produced by the food during baking naturally converges towards the lower center. This design prevents oil from flowing freely on the surface of the baking plate, greatly simplifies the cleaning process, and helps keep the food baking area relatively dry, thereby improving the baking effect and quality.

[0029] As an optional embodiment, the thickness of the baking plate body is less than 10mm.

[0030] The thickness of the baking plate in this application is less than 10mm, making the baking plate lighter and thinner. While ensuring functionality, it reduces the use of materials, lowers production costs, and is also easy to carry and store, thus improving the practicality and portability of the product.

[0031] The beneficial effects of the embodiments of this application are as follows:

[0032] This application utilizes multiple independent grilling zones, heating elements, and temperature probes to achieve individual temperature control in different areas, enhancing cooking flexibility and efficiency and meeting diverse cooking needs. The bottom outer shell layer is detachably connected to the food heating layer, facilitating cleaning of all areas inside the grill plate and enhancing product practicality.

Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0046] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0047] An embodiment of this application provides a multi-zone variable temperature baking plate, such as... Figure 1 and Figure 2 As shown, the baking plate body 1 includes a food heating layer 11, a heating layer 12, multiple temperature probes 13, a bottom outer shell layer 14, and a control module 2.

[0048] The food heating layer 11 has multiple grilling zones 111 for heating food, and the food heating layer 11 can be made of a thin metal plate or other heat-conducting thin plate.

[0049] The heating layer 12 is disposed below the food heating layer 11, and the heating layer 12 includes a plurality of heating elements 121 corresponding to the plurality of grilling zones 111 respectively. The heating element 121 is a metal heating wire or other heating element.

[0050] Multiple temperature probes 13 are respectively disposed between the heating element 121 and the corresponding grilling zone 111, and connected to the corresponding grilling zone 111 to detect the cooking temperature of each grilling zone 111.

[0051] The bottom outer shell layer 14 is located on the lower side of the heating layer 12 and is detachably connected to the food heating layer 11. The bottom outer shell layer 14 may be made of metal or plastic materials.

[0052] The control module 2 is connected to the heating element 121 and the temperature probe 13 respectively, and is used to control the opening and closing of the corresponding heating element 121 according to the temperature detected by the temperature probe 13.

[0053] In this embodiment, "multi-zone" refers to the fact that the entire surface of the food heating layer 11 of the baking plate is divided into multiple independent parts according to the positions of the multiple heating elements 121. There are no clear boundaries between these independent parts, and each part is a zone used to cook different foods. For example, the baking plate can be divided into three zones: left, center, and right. The temperature of each zone can be adjusted independently to meet different needs. For example, the left zone can be set to 180°C for grilling steak, while the right zone can be disabled.

[0054] Temperature probe 13 is a sensor used to sense temperature, which converts temperature signals into electrical signals and transmits them to control module 2. Control module 2 receives the signals from temperature probe 13 and controls the working state of heating element 121 according to a preset program, and is responsible for coordinating the temperature control of the baking plate.

[0055] After the grill plate is started, depending on the type and quantity of the food being grilled, if only one grilling zone 111 is needed, at least one heating element 121 corresponding to the grilling zone 111 in the heating layer 12 will be activated to heat the grilling zone 111. Simultaneously, the corresponding temperature probe 13 monitors temperature changes in real time. When the temperature reaches the set temperature for its corresponding grilling zone 111, the temperature probe 13 feeds back the temperature data to the control module 2.

[0056] Alternatively, after the baking plate is activated, the heating elements 121 corresponding to each grilling zone 111 in the heating layer 12 start working synchronously to heat all grilling zones 111 on the food heating layer 11. The temperature probes 13 corresponding to each grilling zone 111 monitor the temperature changes in real time. When the temperature reaches 180±10 degrees Celsius, the temperature probes 13 feed back the temperature data to the control module 2.

[0057] If the temperature remains within the above temperature range, the control module 2 controls the corresponding heating wire to turn off the power; if the temperature is lower than this range, the control module 2 controls the corresponding heating wire to turn on the power and reheat.

[0058] During the grilling process, when food is placed in a grilling zone 111, heat is lost due to absorption by the food. At this time, the temperature probe 13 corresponding to that grilling zone 111 sends temperature change data over a certain period of time to the control module 2. The control module 2 then controls the corresponding heating element 121 to start heating based on this data to maintain a stable temperature. If no food is placed in a grilling zone 111, the temperature probe 13 in that area also sends temperature change data over a certain period of time to the control module 2. The control module 2 then controls the corresponding heating wire to cut off power to avoid energy waste.

[0059] This application utilizes multiple independent grilling zones 111, heating elements 121, and temperature probes 13 to achieve individual temperature control in different areas, enhancing cooking flexibility and efficiency and meeting diverse cooking needs. The bottom outer shell layer 14 and the food heating layer 11 are removable, facilitating cleaning of the various areas inside the grill plate and enhancing product practicality.

[0060] like Figure 3 As shown, in another embodiment, the baking plate body 1 further includes an insulating and heat-conducting layer 15 and an insulating layer 16. The insulating and heat-conducting layer 15 may be made of mica sheet or other insulating and heat-conducting materials, and the insulating layer 16 may be made of mica sheet or other insulating and high-temperature resistant materials.

[0061] The insulating and heat-conducting layer 15 is disposed between the food heating layer 11 and the heating layer 12, and is used to transfer the heat generated by the heating layer 12 to the food heating layer 11. The insulating layer 16 is disposed between the heating layer 12 and the bottom outer shell layer 14.

[0062] In this embodiment, when the heating element 121 of the heating layer 12 generates heat, the heat is evenly transferred to the food heating layer 11 through the insulating heat-conducting layer 15, allowing the food placed on it to be heated. At the same time, the insulating heat-conducting layer 15 and the insulating layer 16 further enhance the insulation performance of the baking plate, providing users with more reliable safety protection, while reducing heat loss to the bottom outer shell layer 14 and improving energy utilization efficiency.

[0063] like Figure 3 As shown, in one embodiment, the baking plate body 1 further includes a heat insulation layer 17, which is disposed between the insulating layer 16 and the bottom outer shell layer 14. The heat insulation layer 17 may be made of heat insulation cotton or other heat-resistant insulating materials.

[0064] In this embodiment, after heat is transferred from the heating layer 12 to the food heating layer 11 via the insulating heat-conducting layer 15, the heat insulation layer 17 prevents the heat from continuing to be conducted to the bottom outer shell layer 14, so that more heat is concentrated in the food heating layer 11.

[0065] The insulation layer 17 reduces heat loss, allowing more heat to be used for heating food, improving energy efficiency and reducing energy consumption. At the same time, it prevents the bottom outer shell layer 14 from overheating, avoiding accidental burns to the user and enhancing product safety.

[0066] like Figure 4 As shown, in one embodiment, the baking plate further includes a foot 3, the upper end of the foot 3 is provided with a foot insertion interface 31, and the lower side of the bottom outer shell layer 14 is provided with a baking plate insertion interface. The foot 3 is electrically connected to the baking plate insertion interface through the foot insertion interface 31, and the two are detachably connected.

[0067] In this embodiment, when assembling the baking plate, the bottom foot 3's insertion interface 31 is aligned with the baking plate insertion interface on the lower side of the bottom outer shell layer 14, inserted and fixed to complete the support installation of the baking plate. For disassembly, the bottom foot 3 and the baking plate body 1 can be separated by reversing the operation.

[0068] The base 3 of this application is detachably connected to the baking plate body 1 via a plug interface, which makes it easy to disassemble the baking plate during transportation and store it. At the same time, the base 3 can be flexibly replaced according to actual usage needs (such as replacing the base 3 with different heights to adapt to different countertops), increasing the convenience of use.

[0069] like Figure 4 As shown, in one embodiment, the base 3 is provided with a control knob 32 that is electrically connected to the control module 2. By operating the control knob 32, the control module 2 can control the power supply to the heating layer 12.

[0070] In this embodiment, the user rotates the control knob 32 on the foot 3, which converts the rotation angle into an electrical signal and transmits it to the control module 2. The control module 2 controls the power supply to the heating layer 12 based on the received signal.

[0071] This application eliminates the need to find operation buttons on the baking plate body 1. The heating layer 12 can be powered on and off directly by the control knob 32 at the bottom of the baking plate, simplifying the structural design of the baking plate body 1, making it convenient for users to operate and improving the user experience.

[0072] In another embodiment, the control knob 32 also has a temperature adjustment function, which can adjust the grilling temperature according to the type of food being grilled. For example, when grilling meat, the grilling temperature is adjusted to about 180°C, and when grilling vegetables, the grilling temperature is adjusted to about 130°C.

[0073] like Figure 4 As shown, in one embodiment, the base 3 is provided with a power cord plug interface 33, which is connected to an external power source.

[0074] In this embodiment, the external power cord plug is inserted into the power cord socket 33 on the base 3. Current enters the base 3 through the power cord socket 33. Since the base 3 is electrically connected to the baking plate, when the base 3 is connected to the baking plate, current enters the internal circuitry of the baking plate to power it and enable it to work normally. This application places the power cord socket 33 on the base 3, making the power cord connection more reasonable and convenient, avoiding the inconvenience (such as affecting the placement of the baking plate) and safety hazards (such as tripping over tangled power cords) caused by connecting the power cord to the baking plate body 1, and making the overall appearance of the baking plate simpler and more aesthetically pleasing.

[0075] like Figure 3As shown, in one embodiment, at least two grilling zones 111 are provided, and the grilling areas of the two grilling zones 111 are the same or different.

[0076] In this embodiment, the user selects a suitable grilling area 111 to place the food according to the size of the ingredients and cooking needs. For example, a larger steak is placed in a larger grilling area 111, while small meatballs are placed in a smaller grilling area 111. The heating element 121 heats the corresponding grilling area 111, the temperature probe 13 monitors the temperature, and the control module 2 adjusts the temperature to complete the food cooking process.

[0077] This application sets up at least two grilling zones 111 with different areas to meet the diverse needs of different ingredients and cooking methods for grilling area, enriching cooking possibilities and improving the practicality of the grilling plate.

[0078] like Figure 2 As shown, in one embodiment, the area of ​​the heating element 121 is matched with the area of ​​the corresponding grilling area 111, and the position of the temperature probe 13 corresponds to the center position of the corresponding grilling area 111.

[0079] In this embodiment, after the heating element 121 starts working, its area matches the area of ​​the corresponding grilling area 111, and the heat is evenly distributed within the grilling area 111. The temperature probe 13 is located at the center of the grilling area 111, which detects the temperature of the area in real time and feeds the data back to the control module 2. The control module 2 accurately adjusts the working state of the heating element 121 according to the feedback data to maintain the temperature of the grilling area 111 stable.

[0080] The heating element 121 of this application matches the area of ​​the grilling zone 111 to ensure uniform heat distribution, prevent local overheating or underheating, ensure even heating of food, and improve cooking quality. The temperature probe 13 is located in the center to provide accurate temperature data to the control module 2, enabling precise temperature control.

[0081] like Figure 1 As shown, in one embodiment, the baking plate body 1 has a curved structure, and the portion of the baking plate body 1 near its center is lower than the portion near its outer periphery.

[0082] In this embodiment, during the cooking process, the oil and other liquids produced by the food flow from the outer periphery (higher position) to the center (lower position) of the baking plate body 1 under the action of gravity, making it convenient for the user to set up a container to collect the oil.

[0083] The curved design of the baking plate body 1 in this application makes it easy to collect the oil produced during cooking, reduce the amount of food soaked in oil, make cooking food healthier, and also reduce the difficulty of cleaning and make it easier to clean the baking plate.

[0084] In one embodiment, the thickness of the baking plate body 1 is less than 10 mm. With a thickness of less than 10 mm, the baking plate body 1 achieves a slim and lightweight design while ensuring various functions such as multi-zone variable temperature control.

[0085] In summary, when this application is used, before the baking plate is started, the base 3 is first connected to the baking plate interface on the lower side of the bottom outer shell layer 14 through the base plug interface at the upper end to complete the assembly of the baking plate support structure. Then, the external power cord is inserted into the power cord plug interface 33 on the base 3 to turn on the power.

[0086] After the baking plate is started, at least one heating element 121 in the heating layer 12 is activated according to the usage requirements to heat the grilling area 111 corresponding to the heating element 121; if all heating elements 121 are activated, all grilling areas 111 on the food heating layer 11 are heated.

[0087] Temperature probes 13 corresponding to each grilling zone 111 monitor temperature changes in real time. When the temperature reaches 180±10 degrees Celsius, the temperature probes 13 feed the temperature data back to the control module 2. If the temperature remains within this range, the control module 2 controls the corresponding heating wire to turn off the power; if the temperature is lower than this range, the control module 2 controls the corresponding heating wire to turn on the power and reheat.

[0088] During the grilling process, when food is placed in a grilling zone 111, heat is lost due to absorption by the food. At this time, the temperature probe 13 corresponding to that grilling zone 111 sends temperature change data over a certain period of time to the control module 2. The control module 2 then controls the corresponding heating element 121 to start heating based on this data to maintain a stable temperature. If no food is placed in a grilling zone 111, the temperature probe 13 in that area also sends temperature change data over a certain period of time to the control module 2. The control module 2 then controls the corresponding heating wire to cut off power to avoid energy waste.

[0089] Throughout the process, the insulating and heat-conducting layer 15 efficiently transfers the heat generated by the heating layer 12 to the food heating layer 11, ensuring that the food is heated normally, while also playing an insulating role to prevent the heating layer 12 from leaking electricity. The insulating layer 16 further enhances the insulation performance and reduces the risk of leakage, while the heat insulation layer 17 reduces the loss of heat to the bottom outer shell layer 14, improves energy utilization, and prevents the bottom outer shell layer 14 from overheating and causing the risk of burns.

[0090] If the user wants to adjust the temperature or control the working status of the baking plate, they can operate the control knob 32 on the base 3, which is electrically connected to the control module 2. The signal generated by the control knob 32 is transmitted to the control module 2, and the control module 2 controls the power supply of the heating layer 12 or adjusts the heating power accordingly.

[0091] During cooking, because the main body 1 of the baking plate has a curved structure, with the central part lower than the outer perimeter, the oils and other liquids produced by the food automatically flow to the outer perimeter of the baking plate under the influence of gravity, making them easy to collect and reducing the amount of oil soaking in the food, resulting in healthier cooking and easier cleaning. The thin design of the main body 1, less than 10mm thick, ensures the normal operation of all functions while being easy to carry and store, enhancing the product's practicality and portability.

[0092] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
