[0073] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0074] Reference Figures 3 to 7 This application provides a cooking appliance 10. The cooking appliance 10 according to this application can be a rice cooker, electric pressure cooker or other cooking appliances 10 with heating function, and the cooking appliance 10 can have various functions such as cooking porridge in addition to cooking rice.

[0075] The cooking appliance 10 of this utility model includes a lid 15 and a pot body 11. The pot body 11 is used for cooking food, and the lid 15 is used to cover the pot body 11. When the lid 15 covers the pot body 11, a cooking space is formed between the lid 15 and the pot body 11.

[0076] The pot body 11 includes a shell 12, which is typically a rounded cuboid shape and has a cylindrical inner pot storage section. The inner pot 13 is housed inside the shell 12. The inner pot 13 can be freely inserted into or removed from the inner pot storage section for easy cleaning. The inner pot 13 is typically made of metal and is used to hold materials to be heated, such as rice or soup.

[0077] A heating device 14 is provided inside the lid 15 and / or the pot body 11. The heating device 14 is capable of heating the inner pot 13.

[0078] The cooker body 11 is also equipped with a control device 40. The control device 40 may be, for example, a microcontroller unit (MCU) for controlling the cooking process of the cooking appliance 10. The heating device 14 is electrically connected to the control device 40.

[0079] The lid 15 has a shape substantially corresponding to the pot body 11. The lid 15 is closable on the pot body 11; specifically, it is pivotally connected to the pot body 11 via a pivot axis and can freely pivot about the pivot axis between a closed position and an open position relative to the pot body 11, facilitating the closing and opening of the pot body 11. When the lid 15 closes the pot body 11, a sealed connection is formed between the lid 15 and the inner pot 13. Optionally, the lid 15 can close onto either the outer shell 12 or the inner pot 13. (See reference...) Figures 3 to 5 The cover 15 is then fitted onto the housing 12. (See reference.) Figure 6 The lid 15 is closed to the inner pot 13.

[0080] The cover 15 includes a top cover, a liner, and a removable cover. The top cover is located on the outermost side of the cover 15, forming the outer shell of the cover 15. The liner is located below the top cover and is connected to the top cover. For example, the liner can be connected to the top cover by fasteners or snaps. The top cover and the liner together form the upper cover assembly. The upper cover assembly is mainly used to centrally mount various functional components of the cover 15 that sense and control the working status of the cooking appliance 10, such as sensors. The removable cover is located on the innermost side of the cover 15 and is located below the liner. The removable cover is detachably connected to the liner, for example by snaps, for easy cleaning and replacement. The removable cover is oriented towards the cooking space, that is, when the cover 15 is in the closed position, the removable cover is directly above the cooking space.

[0081] The cooking appliance 10 also includes a temperature sensing element 16 for measuring temperature. Optionally, the temperature sensing element 16 is a temperature sensor.

[0082] It should be noted that the directional terms used in this article to describe the various components and parts of the pot body 11, such as "up," "down," "above," "below," "upward," "downward," "facing upward," and "facing downward," are relative to the pot body 11 when it is placed horizontally and upright. Unless otherwise specified, "inner" in the directional terms "inward," "outward," "towards," "inner side," and "outer side" refers to the area near the center of the pot body 11, and "outer" refers to the area away from the center of the pot body 11.

[0083] As people's demands for healthy eating and culinary results increase, cooking appliances 10 need to be more intelligent and versatile to meet user needs. Cooking appliances 10 can be equipped with various inner pots 13, allowing users to choose the appropriate inner pot 13 according to different cooking needs, eliminating the need to purchase multiple different cooking appliances 10, thus saving space and cost. Optionally, cooking appliances 10 can be configured with a dedicated program for each inner pot 13, but the method of identifying the inner pot 13 has certain limitations.

[0084] For example, to distinguish between pot interiors 13 made of different materials and of different types, some solutions determine whether the pot interior 13 is made of iron by detecting whether the magnetic field strength is greater than a set magnetic field strength threshold; if it is less than the threshold, it is determined to be a ferromagnetic ceramic pot interior 13. However, this method can only detect whether the pot interior 13 is made of iron or non-iron materials.

[0085] Other solutions use magnetic coding rings in conjunction with Hall sensor arrays or physical protrusions of the pot liner 13 in conjunction with microswitches to identify different pot liners 13. Although these methods can achieve certain identification functions, they are complex in structure, costly, and prone to failure due to poor physical contact or damage to the coding ring.

[0086] Some other solutions attempt to identify the material type of the inner pot 13 by the difference in heating rate, but this method requires high precision from the heating device 14 and is easily affected by environmental factors and initial conditions in practical applications, resulting in unstable identification results.

[0087] Therefore, how to reduce system complexity and cost while ensuring recognition accuracy and reliability is an urgent problem to be solved in the current design of multi-pot cookware 10.

[0088] Reference Figure 1 and Figure 2The cooking appliance 10 provided in this solution includes a pot inner information carrier 20 and an information reading device 30. The pot inner information carrier 20 is disposed on the pot inner 13 and is used to store pot inner information. Optionally, the pot inner information includes at least one of the pot inner 13's material, geometric dimensions, and surface coating parameters. The information reading device 30 is disposed on the pot body 11 or the lid 15 and is used to acquire the pot inner information. The information reading device 30 is electrically or communicatively connected to a control device 40. The control device 40 is configured to acquire the pot inner information read by the information reading device 30 and control the heating device 14 to operate according to the corresponding working mode based on the pot inner information.

[0089] Optionally, the control device 40 adjusts the power, heating time and other parameters of the heating device 14 through the control circuit based on the acquired pot information, so that the heating device 14 works according to the corresponding working mode. For example, for pots 13 made of different materials, the control device 40 can adjust the heating power to achieve the best cooking effect.

[0090] In this solution, the information reading device 30 accurately identifies information about different inner pots 13. The control device 40, based on the characteristics of different inner pots 13, controls the heating device 14 to operate according to the corresponding working mode. This satisfies the user's requirement to select the appropriate inner pot 13 according to different cooking needs, realizing the intelligence and versatility of the cooking appliance 10 and providing users with a better cooking experience. This solution eliminates the need for complex structural connections, reducing hardware costs and system design complexity. It also avoids system failures due to poor contact, reducing maintenance costs. With this solution, users do not need to purchase multiple different types of cooking appliances 10 to meet different cooking needs; they only need to replace the inner pot 13 as needed, saving kitchen space and purchase costs.

[0091] In this solution, the pot interior information carrier 20 is communicatively connected to the information reading device 30. The information reading device 30 includes a second wireless communication module 31. The second wireless communication module 31 enables wireless communication with the pot interior information carrier 20, allowing for rapid acquisition of pot interior information without complex physical connections, thus improving the ease of use of the cooking appliance. The second wireless communication module 31 is located on the pot body 11 or the lid 15; specifically, it is located on the shell 12 or the lid 15. The information reading device 30 communicates directly or indirectly with the pot interior information carrier 20 through the second wireless communication module 31. Optionally, the second wireless communication module 31 is an NFC module. NFC modules have advantages such as short communication distance, high security, and fast connection speed, enabling rapid reading of pot interior information and improving the efficiency of the cooking appliance.

[0092] Reference Figure 1In some embodiments, the pot information carrier 20 includes a first wireless communication module 21. Wireless communication technology enables fast and accurate transmission of pot information without the need for complex physical connection structures, reducing system complexity and cost. Optionally, the first wireless communication module 21 is an RFID tag, which is attached to the pot 13 by pasting, riveting, welding, screwing, or snapping. Multiple connection methods facilitate installation according to actual needs, improving the versatility and practicality of the pot information carrier 20. Optionally, the RFID tag is attached to the pot 13 by adhesive or tape. This adhesive connection eliminates the need for complex tools and equipment; simply apply adhesive or tape evenly to the back of the RFID tag or a designated location on the pot 13, then press the tag onto the pot 13, allowing the adhesive to cure or the tape to adhere firmly. Optionally, the outer surface of the pot 13 has grooves into which the RFID tag can be installed.

[0093] In this solution, the material of the inner pot 13 can be, but is not limited to, metal, ceramic, or glass. When the inner pot 13 is made of metal, the wireless signal of ordinary RFID tags is easily reflected and absorbed by the metal, resulting in severe signal attenuation. This makes it difficult for the information reading device 30 to accurately obtain the information from the tag, or even render it completely unreadable. The information carrier 20 of the inner pot can use an anti-metal RFID tag to effectively overcome the interference of metal on the RFID signal, ensuring stable and reliable operation on the metal inner pot 13.

[0094] The information reading device 30 communicates with the RFID tag of the pot information carrier 20 via an NFC module. Understandably, the information reading device 30 and the RFID tag of the pot information carrier 20 should be compatible. The specific process is as follows: When the pot 13 is placed inside the pot body 11, the pot information carrier 20 enters the magnetic field range of the information reading device 30. The NFC module of the information reading device 30 activates the RFID tag of the pot information carrier 20, putting it into working mode. The NFC module interacts with the RFID tag, reading the pot information stored in the RFID tag. The control device 40 receives the pot information sent by the NFC module of the information reading device 30 and controls the working mode of the cooking appliance 10 through a corresponding program.

[0095] Reference Figure 2 In other embodiments, the boiler information carrier 20 can also be an information identifier, such as a graphic or textual information identifier. Optionally, the information identifier includes a QR code and / or a barcode. Using information identifiers provides users and manufacturers with a simple and intuitive way to store and retrieve information. QR codes and barcodes have advantages such as large information storage capacity, accurate identification, and low cost, facilitating information management and identification for users and manufacturers.

[0096] The information label is connected to the pot liner 13 by printing, pasting, riveting, welding, screwing, or snap-fitting. Printing refers to printing, engraving, or integrally molding the information label onto the surface of the pot liner 13. Pasting, riveting, welding, screwing, or snap-fitting connections refer to placing the information label on a sheet-like structure, which is then connected to the pot liner 13 using these methods. These multiple connection methods facilitate the installation of the pot liner information carrier 20 and reduce design and production costs.

[0097] The mobile terminal 50 is capable of recognizing information identifiers. Optionally, the mobile terminal 50 is equipped with an NFC module. The mobile terminal 50 is communicatively connected to the information reading device 30 module. It is understood that the NFC module of the mobile terminal 50 and the information reading device 30 should be compatible. The specific process is as follows: The user reads the information identifier (such as a QR code and / or barcode) on the inner pot 13 using the mobile terminal 50 (e.g., a smartphone). The mobile terminal 50 prompts the user to approach the cooking appliance 10. When the mobile terminal 50 approaches the cooking appliance 10, it establishes a communicative connection with the information reading device 30. The NFC module of the mobile terminal 50 receives the inner pot information from the NFC module of the information reading device 30. This inner pot information can be information read by the mobile terminal 50 from a QR code or barcode, or other information related to the inner pot 13 stored by the mobile terminal 50. The control device 40 receives the inner pot information sent by the information reading device 30 module and controls the working mode of the cooking appliance 10 through a corresponding program. Optionally, the information reading device 30 module is disposed on the cover 15 to facilitate communication connection with the mobile terminal 50.

[0098] According to the above embodiments, the information reading device 30 of the cooking appliance 10 can quickly read the pot information via the NFC module, improving the efficiency of the cooking appliance 10. Through information interaction between the cooking appliance 10 and the mobile terminal 50, other functions can also be easily expanded, such as updating information on the mobile terminal 50.

[0099] Optionally, the cooking appliance 10 has an indicator and / or a limiting structure at a corresponding position on the information reading device 30 module. Specifically, the cooking appliance 10 has an indicator and / or a limiting structure at a corresponding position on the second wireless communication module 31. The indicator and limiting structure are used to tell the user the position where the pot information carrier 20 of the inner pot 13 or the mobile terminal 50 needs to be aligned, so that the second wireless communication module 31 can communicate with the first wireless communication module 21 or the third wireless communication module 51. The indicator can be a clear graphic, symbol, or text description, such as a circular pattern with an NFC logo, or a text prompt "Please place your phone here". Optionally, the indicator is located on the cover 15. The limiting structure can be a groove or a protrusion to adapt to the shape of the inner pot 13 or the mobile terminal 50.

[0100] Optionally, the heating device 14 is disposed within the pot body. When the inner pot 13 is located within the pot body 11, the information carrier 20 of the inner pot is offset from the heating device 14. The heating device 14 generates high temperatures during operation. If the information carrier 20 is directly exposed to this high temperature, its internal electronic components (such as the RFID tag chip, the QR code / barcode printing material, etc.) may be damaged due to overheating. Offsetting the information carrier 20 from the heating device 14 effectively reduces the temperature experienced by the information carrier, preventing damage and extending its lifespan. In electromagnetically heated cooking appliances 10, this offset arrangement also avoids problems such as weakened RFID tag signal strength and data transmission errors caused by electromagnetic interference.

[0101] Reference Figure 8 and Figure 9 Optionally, the information carrier 20 of the boiler liner 13 is disposed on the outer surface of the boiler liner 13. When the information carrier 20 is an RFID tag, the RFID tag and the NFC module are closer together, thereby significantly improving the communication efficiency between the two and making data transmission faster and more accurate. When the information carrier 20 is an information identifier, the design cost and difficulty are reduced, and the identifier can be seen by the user with the naked eye.

[0102] The cooking appliance 10 also includes a temperature sensing element 16. When the inner pot 13 is located within the pot body 11, the information carrier 20 of the inner pot is offset from the temperature sensing element 16. The space within the pot body 11 is limited, requiring the rational arrangement of multiple components such as the inner pot 13, heating device 14, temperature sensing element 16, and information carrier within this limited space. If the positions of the information carrier and the temperature sensing element 16 conflict, it may cause interference between components, affecting the overall design and performance of the cooking appliance 10.

[0103] Optionally, the temperature sensing element 16 is disposed within the pot body 11. In some embodiments, the temperature sensing element 16 can contact the bottom of the inner pot 13, which is the direct contact point for heat transfer from the heating device 14. By measuring the temperature of the bottom of the inner pot 13, the heating process can be precisely controlled. In other embodiments, the temperature sensing element 16 can contact the side wall of the inner pot 13, and the temperature of the side wall can reflect the heat distribution of the food inside the inner pot 13. During cooking, the temperature change of the side wall of the inner pot 13 can provide additional reference information for the control device 40. In this scheme, the inner pot information carrier 20 itself may have a certain influence on the temperature; for example, the inner pot information carrier 20 may locally change the heat conduction path, affecting the temperature sensing element 16's perception of the actual temperature of the inner pot 13. By separating the information carrier 20 of the inner pot from the temperature measuring element 16, interference from the information carrier to the temperature measuring element 16 can be avoided, allowing the temperature measuring element 16 to directly and accurately measure the temperature of the bottom or side wall of the inner pot 13. This provides reliable temperature data for the heating control of the cooking appliance 10, enabling more precise control of the cooking process.

[0104] Optionally, a temperature sensing element 16 is disposed on the lid 15 for measuring the steam temperature within the cooking space. Optionally, the temperature sensing element 16 is disposed on the removable lid, which is located directly above the cooking space when the lid 15 is in the closed position. During cooking, a large amount of steam is generated inside the pot, and the temperature of the steam can reflect the cooking status of the food inside the pot.

[0105] In this embodiment, when the pot information carrier 20 is a wireless communication module such as an RFID tag, it will generate electromagnetic signals during operation. These electromagnetic signals may interfere with the temperature sensor signal of the temperature measuring element 16, leading to inaccurate temperature measurements. Therefore, whether the pot information carrier 20 is located in the pot body 11 or the lid 15, it should be offset from the temperature measuring element 16. This ensures both the measurement accuracy of the temperature measuring element 16 and the normal operation of the pot information carrier 20.

[0106] The application also provides a pot liner identification system. The pot liner identification system includes an identification module 52 and a third wireless communication module 51. The identification module 52 is used to identify the pot liner information in the pot liner information carrier 20 of the pot liner 13. The third wireless communication module 51 is electrically connected to the identification module 52 to obtain the pot liner information and is used for wireless communication with the second wireless communication module 31 of the cooking appliance 10. The identification module 52 can employ corresponding identification technologies depending on the type of the pot liner information carrier 20. For example, when the pot liner information carrier 20 is an RFID tag, the identification module 52 needs to have RFID reading functionality, capable of activating the RFID tag and reading the pot liner information stored therein. When the pot liner information carrier 20 is a QR code or barcode, the identification module 52 can be a camera combined with an image recognition algorithm to scan and parse the QR code or barcode to obtain the pot liner information.

[0107] Optionally, the third wireless communication module 51 is an NFC module.

The user can read the information identifier on the pot 13 by pointing the camera of the mobile terminal 50 at it. The mobile terminal 50 identifies the pot information using built-in identification software (such as a QR code scanner or barcode scanner). The pot information is transmitted to the control device 40 via the NFC module, and the control device 40 adjusts the working mode of the cooking appliance 10 based on the received pot information.

[0109] The aforementioned pot liner recognition system is installed on a terminal device. Optionally, this terminal device is a portable smart mobile terminal 50, such as a mobile phone, tablet computer, or laptop computer. Terminal devices such as mobile phones, tablet computers, or laptop computers have advantages such as high portability, high popularity, and rich functionality, making it convenient for users to identify pot liner information and control cooking appliances anytime and anywhere, thus improving the ease of use and intelligence of cooking appliances.
