[0002] In order to realize the cooking state sensing, the existing smart stove usually integrates sensors in the main body of the stove, but there are obvious deficiencies in actual application. In terms of weighing, the design of integrating the weighing module in the overall base is usually adopted, which causes that multiple stove heads cannot be measured independently at the same time, the system can only obtain the total weight of the stove, cannot distinguish the weight change of the food in a single pot, and needs to be manually zeroed, so it is difficult to realize real-time continuous monitoring. In terms of temperature measurement, the probe is usually fixed near the burner or below the pot bottom, and the measurement value is easily disturbed by the flame heat radiation and the heat conduction of the pot bottom, so it cannot accurately reflect the real temperature of the pot wall and the food in the pot.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Example 1 This invention provides an intelligent stove, comprising: a stove head, a pot rack body 1 corresponding to the stove head, a support piece 3 disposed on the pot rack body 1 near the pot 100, and a foot piece 2 disposed on the pot rack body 1 near the stove surface. The support piece 3 is used to abut against the pot 100 to provide support, and the foot piece 2 is used to support the pot rack body 1. The support piece 3 is equipped with a temperature sensor 32 for detecting temperature information, and the foot piece 2 is equipped with a weight sensor 21 for detecting weight information. The pot rack body 1 is also equipped with a power receiving interface 4, and the stove head is equipped with a power distribution interface corresponding to the power receiving interface 4. The pot rack body 1 and the stove head are electrically connected through the power receiving interface 4 and the power distribution interface, which are used to supply power to the temperature sensor 32 and the weight sensor 21, and to transmit the temperature and weight information to the controller of the intelligent stove to adjust the working state of the stove head.

[0027] Specifically, a smart stove includes the burner and a smart pot rack that comes with it. See [link / reference] Figure 1 The diagram shown is a first-view structural schematic of an intelligent pot rack provided by an embodiment of the present invention. Figure 2The diagram shown is a second-view structural schematic of an intelligent pot rack provided by an embodiment of the present invention. The pot rack body 1 serves as an integral load-bearing frame, typically made of high-temperature resistant metals such as cast iron or stainless steel. Its shape is ring-shaped or frame-shaped, with a central area providing space for flame passage. Support plates 3 protrude upwards and are evenly distributed along the upper periphery of the pot rack body 1, their tops directly contacting and supporting the bottom of the pot 100. Foot plates 2 extend downwards and are located at the lower part of the pot rack body 1, stably supporting the pot rack on the stovetop. A temperature sensor 32 is integrated at the contact point between the support plate 3 and the pot 100, used to sense the temperature of the bottom of the pot 100 in real time. A weight sensor 21 is integrated in the stress concentration area of ​​the foot plates 2, used to sense the weight of the pot 100 and the food. A power receiving interface 4 is installed on the side or at a specific location of the pot rack body 1, used to interface with the power distribution interface on the stovetop, achieving a stable electrical connection between the pot rack and the stovetop, providing operating power to the sensors and optional electronic units on the pot rack, and establishing a data communication channel with the stovetop's main control unit.

[0028] The connection between the power receiving interface 4 and the power distribution interface on the stove head forms the energy and information hub of the entire intelligent sensing system. The core purpose of this connection is to achieve the dual functions of energy supply and data interaction. In terms of energy supply, the power supply circuit formed by the power distribution interface and the power receiving interface 4 inside the stove head provides the necessary operating power to the temperature sensor 32 and weight sensor 21 integrated on the pot rack, enabling them to continuously and stably perform measurement work. In terms of data interaction, this interface simultaneously constitutes a communication bridge between the pot rack and the main controller of the intelligent stove. Real-time temperature information detected by the temperature sensor 32 and real-time weight information detected by the weight sensor 21 can be efficiently and reliably transmitted to the controller of the intelligent stove through the wired communication link established by this interface.

[0029] The controller of the smart stove acts as the "brain" of the system. After receiving real-time, precise status data from the smart pot rack, it executes built-in intelligent control logic to automatically and precisely adjust the stove's operating status. For example, the controller can compare and analyze the real-time collected pot temperature with a preset target temperature curve, dynamically adjusting the opening of the gas proportional valve or the igniter power to achieve closed-loop precise temperature control. The controller can also analyze the weight change trend of the food, automatically determine the cooking stage (such as boiling or reducing sauce), and adjust the heat accordingly. More importantly, the controller can analyze parameters such as temperature change rate to promptly identify safety risks such as dry burning and immediately issue a command to shut off the gas supply, achieving proactive safety protection. This transforms the originally single-function stove into an intelligent terminal capable of sensing the cooking environment, automatically executing strategies, and ensuring cooking safety when equipped with a smart pot rack.

[0030] Furthermore, in some preferred embodiments of the present invention, the power receiving interface 4 is provided with two first pins 41; the power distribution interface is provided with two first metal contacts; the first pins 41 and the first metal contacts correspond one-to-one; the pot rack body 1 and the stove head form a power supply circuit through the first pins 41 and the first metal contacts, so that the pot rack body 1 receives the power energy of the power supply module of the smart stove through the power supply circuit to power the temperature sensor 32 and the weight sensor 21.

[0031] For details, see Figure 3 The diagram shown is a structural schematic of a power receiving interface 4 provided by an embodiment of the present invention. Figure 4 The schematic diagram of a power distribution interface provided in this embodiment of the invention shows that the first pin 41 is typically a metal spring pin with good conductivity and elasticity, installed inside the insulating shell of the power receiving interface 4; the corresponding first metal contact is a closed metal contact protruding from the stove panel. When the pot rack is placed on the stove and aligned, the shell of the power receiving interface 4 completely covers the outside of the power distribution interface, and the end of the first pin 41 presses against the corresponding first metal contact under the action of the spring, forming a close electrical contact with low resistance, thereby establishing a power supply path from the stove power supply module to the pot rack, ensuring reliable power transmission. At the same time, the closed contact avoids the problem of traditional plug-type interfaces accumulating oil and dirt and being difficult to clean in the kitchen environment.

[0032] Furthermore, in some preferred embodiments of the present invention, a control unit is also provided on the pot rack body 1; a second pin 42 is also provided in the power receiving interface 4; a second metal contact is also provided in the power distribution interface; the second pin 42 and the second metal contact correspond one-to-one; the pot rack body 1 and the stove head form a communication circuit through the second pin 42 and the second metal contact, so that the control unit sends temperature information and weight information to the controller of the smart stove through the communication circuit; the controller of the smart stove is used to adjust the working state of the stove head based on the temperature information, weight information and preset automatic cooking instructions, or to adjust the working state of the stove head based on the temperature information and preset anti-dry burning conditions.

[0033] Specifically, the control unit, as the local processing core of the pot rack, is responsible for collecting and initially processing the analog signals from the temperature sensor 32 and the weight sensor 21, performing analog-to-digital conversion, digital filtering, and data calibration. (See also...) Figure 3 and Figure 4The second pin 42 and the second metal contact together form a wired communication link between the pot rack and the main unit of the stove. This communication circuit can use standard serial communication protocols such as UART and I2C. The control unit uploads processed data such as temperature and weight to the main controller of the stove in real time through this circuit. As the core control component of the smart stove, the main controller of the stove performs advanced cooking logic judgment and precise firepower control based on this: In automatic cooking mode, combined with recipe programs obtained from the cloud or local storage, it dynamically and precisely adjusts the gas proportional valve, igniter and other actuators of the burner to achieve automatic stepless adjustment of firepower, so as to complete the entire process of programmed cooking from stir-frying and boiling to simmering and reducing sauce. At the same time, by analyzing the real-time change rate of pot temperature, it can promptly judge the risk of dry burning and immediately cut off the gas supply to the burner and turn off the flame through the main controller, or issue an alarm through the indicator on the pot rack, so as to achieve active safety protection.

[0034] Furthermore, in some preferred embodiments of the present invention, the smart stove or pot rack body 1 is also provided with a wireless communication unit, which is used to establish a communication connection with the range hood; the control unit is also used to send temperature information to the range hood through the wireless communication unit, so that the range hood adjusts its working state according to the temperature information and preset control conditions.

[0035] Specifically, a wireless communication unit, such as a Bluetooth Low Energy (BLE), Wi-Fi, or Zigbee module, is integrated into the pot rack body 1 as a supplement or alternative to wired communication. It operates by receiving power from the pot rack via the power receiving interface 4. This design greatly expands the smart stove's ability to function as a kitchen control hub, constituting a key feature of the intelligent cooking system. For example, when the control unit processes data from the temperature sensor 32 and determines that the pot 100 temperature exceeds a preset threshold for smoke generation (e.g., entering the stir-frying stage), it can automatically send a start signal and set a high airflow command to the controller of the intelligent range hood via the wireless communication unit; when cooking is finished and the pot temperature drops, it can instruct the range hood to enter a delayed shutdown mode to remove residual smoke. The wireless communication unit can also send the cooking status (such as current temperature, remaining weight, cooking stage) sensed by the pot rack and its own status information to a wider network of smart devices. The receiving end may include the smart kitchen hub, other stoves, smart ovens or the user's mobile terminal, completely eliminating the physical cable constraints between the pot rack and fixed equipment, making the placement, removal and cleaning of the pot rack more free and convenient, and realizing intelligent scenario-based collaboration across devices.

[0036] Furthermore, when the wireless communication unit is installed on the smart stove, the control unit on the pot rack body 1 sends the temperature information to the controller of the smart stove through the communication loop. The controller of the smart stove then sends the temperature information to the range hood, so that the range hood adjusts its working state according to the temperature information and preset control conditions.

[0037] Furthermore, in some preferred embodiments of the present invention, the top of the first pin 41 and the second pin 42 are provided with a spring-loaded structure so that the pins can achieve stable contact with the corresponding metal contact parts.

[0038] For details, please refer to [link / reference]. Figure 3 The spring-loaded structure typically refers to a miniature spring located at the tail of the pin. When the receiving interface 4 connects to the distribution interface, the pin continuously applies a positive pressure to the corresponding metal contact under the action of the internal spring. The elastic contact can compensate for manufacturing tolerances, thermal expansion and contraction, and slight vibrations during use, ensuring the continuous stability of the electrical connection throughout the cooking process, preventing power outages or signal interruptions due to poor contact, and ensuring the reliability of the system operation.

[0039] Furthermore, in some preferred embodiments of the present invention, the support end of the support piece 3 is provided with a support 31 for supporting the cookware 100, and the support 31 is connected to the support end of the support piece 3 via a universal joint; the probe of the temperature sensor 32 is retractably disposed in the support 31, and a heat insulation layer is provided between the support 31 and the temperature sensor 32.

[0040] For details, see Figure 5 The schematic diagram of a partial support plate 3 provided in the embodiment of the present invention shows that the end of the support plate 3 is connected to a support 31 via a universal joint (e.g., a ball joint structure). The support 31 is a component that directly contacts the bottom of the pot, allowing it to adapt to different pot bottom curvatures and ensure a large-area tight fit. The temperature sensor 32's temperature probe is retractably mounted in the internal cavity of the support 31 via an elastic mechanism such as a spring. When the pot 100 is placed, the probe is elastically pressed against the surface of the pot 100. A high-performance heat-insulating material is filled between the probe and the metal shell of the support 31 to form a heat insulation layer. This combination of "retractable probe + heat insulation layer" structure ensures stable contact between the temperature probe and the pot wall to establish a dominant heat conduction path, while effectively isolating the heat conducted from the high-temperature pot 100 to the entire support 31 and the radiant heat from the flame below, greatly improving the accuracy and response speed of temperature measurement.

[0041] Furthermore, in some preferred embodiments of the present invention, the pot frame body 1 is provided with a plurality of support plates 3, and at least one support plate 3 is provided with a temperature sensor 32 at its end; the pot frame body 1 is provided with a plurality of foot plates 2, and at least one foot plate 2 is provided with a weight sensor 21 at its root.

[0042] For details, please refer to [link / reference]. Figure 1 and Figure 2 The pot frame body 1 is typically provided with three or more circumferentially distributed support plates 3 to achieve stable support. Figure 1 and Figure 2Each unit has four support plates 3. A temperature sensor 32 can be integrated into one of the support plates 3, or preferably within the support 31 of multiple support plates 3. Through multi-point temperature measurement, the control unit can fuse the data (e.g., by averaging or monitoring extreme values), overcoming single-point measurement errors caused by uneven heating of the pot 100 and unevenness of the pot bottom, thus obtaining a more reliable representative pot temperature. Similarly, multiple feet 2 are provided below the pot support. Figure 1 and Figure 2 Each cooker has four foot plates 2. A weight sensor 21 is integrated into the base of at least one foot plate 2. By measuring the force on one or more foot plates 2 and combining it with a calibrated weight distribution model, the total weight of the cookware 100 and the food can be accurately calculated. This design enables each cookware rack on the smart stove to have independent weighing capacity, thereby achieving simultaneous cooking on multiple burners and allowing independent, synchronous, and accurate monitoring of the status of each cookware 100.

[0043] Furthermore, in some preferred embodiments of the present invention, the power receiving interface 4 is provided with a first foolproof part, and the power distribution interface is provided with a second foolproof part. The first foolproof part and the second foolproof part cooperate with each other so that the power receiving interface 4 and the power distribution interface can only be connected by a unique positional relationship.

[0044] For details, please refer to [link / reference]. Figure 3 and Figure 4 The first and second anti-misplacement features are physical structures designed into the interface housing, such as asymmetrical slots and protruding keys, and guide rails of a specific shape. When the user places the pot rack, only when the anti-misplacement features are fully aligned and matched can the power receiving interface 4 and the power distribution interface be successfully plugged in and connected. This effectively prevents interface misalignment, pin bending, or electrical short circuits caused by incorrect placement, ensuring the correctness and safety of each connection.

[0045] Furthermore, in some preferred embodiments of the present invention, an indicator is also provided on the pot rack body 1.

[0046] Specifically, the indicator can be a set of multi-color LEDs or a small buzzer, mounted on the pot rack body 1 in a location easily observed by the user, such as the edge. The indicator is powered by the pot rack circuitry and controlled by the control unit. It provides intuitive status feedback to the user, such as indicating the current cooking stage, communication status, or measurement status through different colored lights or flashing patterns, or issuing audible and visual alarms when abnormalities such as dry-burning risk or overloading are detected, enhancing the intuitiveness and safety of human-machine interaction.

[0047] This invention provides a smart stove, comprising: a burner head, a pot rack body 1 corresponding to the burner head, a support piece 3 disposed on the pot rack body 1 near the pot 100, and a foot piece 2 disposed on the pot rack body 1 near the stove surface. The support piece 3 is used to abut against the pot 100 to provide support, and the foot piece 2 is used to support the pot rack body 1. The support piece 3 is equipped with a temperature sensor 32 for detecting temperature information, and the foot piece 2 is equipped with a weight sensor 21 for detecting weight information. The pot rack body 1 is also equipped with a power receiving interface 4, and the burner head is equipped with a power distribution interface corresponding to the power receiving interface 4. The pot rack body 1 and the burner head are electrically connected through the power receiving interface 4 and the power distribution interface, which are used to supply power to the temperature sensor 32 and the weight sensor 21, and to transmit temperature and weight information to the controller of the smart stove to adjust the working state of the burner head. By independently setting the temperature and weight sensors 21 on the pot rack, each burner head can synchronously, accurately, and without interference monitor the pot temperature and food weight. The pot rack connects to the stove head via a plug-and-play interface, eliminating the need for complex modifications and wiring to the main stove body. This significantly reduces system costs and installation complexity, providing a reliable data foundation for the smart stove to achieve precise temperature control, anti-dry burning, and automatic cooking.

[0048] Example 2 Based on the above embodiments, this invention provides an intelligent cooking system, including: an intelligent stove as provided in the above embodiments and a linkage device corresponding to the intelligent stove.

[0049] Specifically, the intelligent cooking system uses a smart stove with integrated smart pot racks as its core sensing and control terminal. Linked devices mainly include the smart stove's main controller and a smart range hood, and can be expanded to a smart kitchen hub, user mobile terminals, and smart storage devices. Through the high-precision, real-time status sensing achieved by the smart pot racks, the system not only drives the automatic control of the smart stove itself but also enables rich cross-device intelligent scene linkages: In automatic cooking mode, the smart stove's main controller dynamically and precisely adjusts the gas valve, igniter, and other actuators based on accurate temperature and weight data received from the corresponding burner's pot rack, combined with preset recipes or recipes retrieved from the cloud, to achieve automatic, stepless adjustment of the firepower. Simultaneously, by analyzing the real-time rate of change in pot temperature or abnormal weight reduction, the system can promptly identify the risk of dry burning and immediately shut off the gas supply via the main controller or issue an alarm via an indicator on the pot rack.

[0050] The system supports deep cross-device scenario-based interaction, which is a prominent feature of this intelligent cooking system. For example: Cooktop and range hood linkage: When the smart pot rack detects that the temperature of the pot exceeds the preset threshold for oil fume generation (such as when entering the stir-frying stage), its control unit can automatically send a start signal to the controller of the smart range hood through the wireless communication unit and set an appropriate air volume; when cooking is finished and the pot temperature drops, it can instruct the range hood to delay turning off to remove residual smoke.

[0051] Recipe collaboration and ingredient management: The weight data monitored in real time by the smart pot rack can be synchronized to the smart kitchen hub or the user's mobile app. Combined with preset recipes, the system can remind the user when a specific weight of ingredients or seasonings needs to be added, or link with smart refrigerators and storage cabinets to indicate the amount of ingredients in stock.

[0052] Integrated energy and safety across the entire kitchen: The main controller for the cooktop can aggregate the status of each burner and coordinate with smart gas meters, smoke detectors, and other devices to achieve gas safety monitoring and early warning.

[0053] The entire system combines high-precision local status sensing, reliable data communication (wired and wireless), intelligent centralized control, and flexible cross-device linkage to create a safe, convenient, precise, and highly collaborative automated intelligent cooking environment.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
