Description

Technical Field

[0001] This invention relates to the field of smart home technology, and in particular to a smart pot rack and a smart cooking system. Background Technology

[0002] Traditional cooktops have purely mechanical pot supports that only provide structural support and cannot sense cooking information. To achieve automated cooking, existing technologies primarily employ two methods: one is to integrate sensors into the cooktop itself for indirect temperature measurement, but this is affected by factors such as the pot's material and placement, resulting in inaccurate and delayed measurements; the other is to develop dedicated smart cookware, but this is costly and limits user choice. Neither method can detect real-time changes in the weight of the food inside the pot, making it difficult to accurately determine the cooking stage. Furthermore, directly installing sensors on the pot support faces technical bottlenecks such as high cooktop temperatures, power supply difficulties under open flame conditions, and unstable signal transmission. Therefore, there is an urgent need for a smart cooking system that can adapt to high-temperature environments, is highly versatile, and can simultaneously and directly sense the temperature and weight of the cookware.

[0024] 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.

[0025] Example 1 This invention provides an intelligent pot rack, comprising: a pot rack body 1, a support piece 3 disposed on the pot rack body 1 near the pot 100, and foot pieces 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 pieces 2 are used to support the pot rack body 1; wherein, the support piece 3 is provided with a temperature sensor 32 for collecting temperature information, and the foot pieces 2 are provided with a weight sensor 21 for collecting weight information; the intelligent pot rack further comprises: a microcontroller and a wireless communication unit, the wireless communication unit being used to establish a communication connection with a corresponding linkage device; the microcontroller being used to control the wireless communication unit to send temperature information and / or weight information to the linkage device, so that the linkage device responds.

[0026] For details, see 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 2 The 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, as the core load-bearing structure, is typically made of high-temperature resistant metal materials such as cast iron or stainless steel, and is ring-shaped or frame-shaped, with a central area reserved for flame passage. On the upper surface of the pot rack body 1, multiple support plates 3 are evenly distributed circumferentially. These support plates 3 protrude upwards, and their tops directly contact and support the bottom of the pot 100, serving as the main support points for the pot 100. On the lower surface of the pot rack body 1, multiple foot plates 2 are provided, extending downwards to stably support the entire pot rack on the stovetop, acting as the load-bearing components between the pot rack and the stovetop. The number of support plates 3 and foot plates 2 can be the same or different, and their positions can be relatively arranged or appropriately staggered; this embodiment does not impose specific limitations.

[0027] like Figure 1 and Figure 2 As shown, to achieve the sensing function, key sensing elements are integrated into the aforementioned support structure. A temperature sensor 32 is built into the top of the support piece 3, the part that directly contacts the cookware 100. This sensor is preferably a thin-film thermistor or a miniature thermocouple attached to the underside of the top contact surface of the support piece 3, to quickly respond to temperature changes at the bottom of the cookware 100 and thus collect temperature information. Weight sensors 21, typically miniature strain gauges or piezoresistive sensors, are installed inside or at the root stress concentration area of ​​each foot piece 2 to sense the slight deformation of the foot piece 2 caused by the weight of the cookware 100 and the food, thereby collecting weight information.

[0028] The microcontroller, serving as the local processing core of the smart pot rack, is integrated into the pot rack body 1. It is responsible for directly acquiring analog signals from temperature sensor 32 and weight sensor 21, and performing preprocessing tasks such as analog-to-digital conversion, digital filtering, and data calibration. By running a preset algorithm, the microcontroller can calculate key parameters in real time, including the instantaneous temperature and trend of the pot 100, and the total weight of the pot 100 and the food, as well as its changes. A wireless communication unit, such as a Bluetooth Low Energy (BLE), Wi-Fi, or Zigbee module, is connected to the microcontroller and is responsible for establishing a wireless data link between the smart pot rack and external devices, transmitting the processed temperature and / or weight information.

[0029] Furthermore, in some preferred embodiments of the present invention, the linkage device is a range hood; the microcontroller is used to control the wireless communication unit to send temperature information to the range hood, so that the range hood adjusts its working state according to the temperature information and preset control conditions; wherein, the working state of the range hood represents the opening and closing of the range hood and the air intake.

[0030] Specifically, as a linked device, the range hood's controller has preset temperature thresholds and control logic corresponding to different cooking stages. When the microcontroller of the smart pot rack sends real-time pot temperature data (100) to the range hood controller via wireless communication, the range hood can respond automatically. For example, when it detects that the pot temperature exceeds the critical point for smoke generation (e.g., 150°C, corresponding to the start of stir-frying), it automatically instructs the range hood to start and adjust to a high fan speed; when the temperature drops to the stewing range (e.g., below 100°C), it automatically reduces the fan speed to save energy and reduce noise; after cooking is finished and the pot temperature drops to a safe range (e.g., below 60°C), it can instruct the range hood to delay shutting down to complete the removal of residual smoke, achieving full automation of the range hood's operation and significantly improving kitchen air quality and energy efficiency.

[0031] Furthermore, in some preferred embodiments of the present invention, the linkage device is a stove; the microcontroller is used to control the wireless communication unit to send temperature information and weight information to the stove, so that the stove can adjust its working state based on the temperature information, weight information and preset automatic cooking instructions, or adjust its working state based on the temperature information and preset anti-dry burning conditions.

[0032] Specifically, the cooktop, as the core interconnected device, receives real-time temperature and weight data from the smart pot rack, enabling it to perform two core functions: Firstly, precise automatic cooking: In automatic cooking mode, the user selects a preset recipe (i.e., automatic cooking instruction), which includes a target temperature curve, the relationship between key weight change points and time. The main controller of the cooktop dynamically compares the received real-time temperature and weight data with the recipe requirements, and accordingly precisely and steplessly adjusts the gas proportional valve to control the heat level and duration. For example, when the water temperature in the pot is detected to have reached the boiling point (100°C), it automatically switches to a low heat for simmering; during the reduction stage, based on the rate of weight reduction detected by the weight sensor 21, it intelligently judges the degree of reduction and accordingly lowers the heat until it is turned off, achieving a standardized product with excellent color, aroma, and taste.

[0033] Secondly, proactive anti-dry-burning protection: In safety protection mode, the system algorithm continues to run. When the temperature sensor 32 detects an abnormal temperature spike (such as a temperature rise exceeding the set safety threshold per unit time) or when the temperature remains at a dangerously high level while the weight sensor 21 shows extremely low weight (close to the weight of an empty pot), the system can immediately determine that there is a risk of dry burning. Subsequently, an emergency command is sent to the main controller of the stove via a wireless communication link, triggering rapid gas supply cutoff and flameout protection, thereby achieving proactive and precise anti-dry-burning safety protection, greatly improving the level of kitchen safety.

[0034] Furthermore, in some preferred embodiments of the present invention, the intelligent pot rack further includes: a heat energy acquisition and conversion module 4 disposed on the pot rack body 1; the temperature sensor 32, the weight sensor 21, the microcontroller and the wireless communication unit are all electrically connected to the heat energy acquisition and conversion module 4; the heat energy acquisition and conversion module 4 converts the acquired heat energy into electrical energy and supplies power to the temperature sensor 32, the weight sensor 21, the microcontroller and the wireless communication unit.

[0035] Specifically, in combination Figure 1 and Figure 2 As shown, the energy of the entire intelligent pot rack comes from the heat energy harvesting and conversion module 4. This module is typically fixed to a significantly heated part of the pot rack body 1 (e.g., the inner wall near the center of the ring) in the form of a modular component. The heat energy harvesting and conversion module 4 utilizes the Seebeck effect of thermoelectric materials (such as semiconductor devices based on bismuth-antimony-tellurium alloys). When there is a temperature difference between the two sides of the module, it can directly convert ambient heat energy (mainly from flame radiation and heat conduction from the high-temperature pot 100) into DC power. Through high-temperature insulated wires, it establishes an electrical connection with the temperature sensor 32, weight sensor 21, microcontroller, and wireless communication unit, forming a complete self-powered system. The electrical energy generated by the module, after necessary internal power conditioning (such as voltage stabilization), directly powers the entire sensing and communication system, enabling the intelligent pot rack to work stably for a long time in the high-temperature, open-flame environment of the stove without any external batteries or power cords, fundamentally solving the power supply problem and safety hazards.

[0036] Furthermore, in some preferred embodiments of the present invention, the smart pot rack further includes: an energy storage module; a thermal energy collection and conversion module 4 is electrically connected to the energy storage module, and the thermal energy collection and conversion module 4 is also used to charge the energy storage module.

[0037] Specifically, the energy storage module can be a high-temperature resistant supercapacitor or a special lithium battery pack, connected to the output of the thermal energy harvesting and conversion module 4, forming a miniature energy buffer and management system. When the stove is at high heat and the power generation of the thermal energy harvesting and conversion module 4 exceeds the system's real-time power consumption, the surplus energy is automatically stored in the energy storage module. When the stove is just ignited, turned off, or at a very low heat level, and the ambient heat is insufficient, causing the power generation to be momentarily insufficient, the energy storage module releases the stored energy to maintain the continuous operation or data retention functions of key modules such as the microcontroller and wireless communication unit. This design effectively mitigates the intermittency and fluctuation of heat supply, ensuring the system's functional continuity throughout the entire cooking cycle and in the short period after the stove is turned off, significantly improving user experience and system reliability.

[0038] 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.

[0039] For details, see Figure 3 The partial schematic diagram of the support plate 3 provided in the embodiment of the present invention shows that the support 31 is a component that directly contacts the bottom of the cookware 100. It is flexibly connected to the end of the support plate 3 through a universal joint (such as a ball joint structure or a flexible metal connector). This design allows the support 31 to have a certain degree of freedom of movement in three-dimensional space. When the user places the cookware 100, regardless of whether the bottom of the pot is flat, round, or slightly uneven, the support 31 can adaptively adjust its surface posture through the universal joint under the weight of the cookware 100, so as to achieve a close fit with the curved surface of the pot bottom with the maximum area. This adaptive fit not only improves the stability of the support, but more importantly, it greatly reduces the thermal resistance caused by poor contact.

[0040] Furthermore, in some preferred embodiments of the present invention, the temperature sensor 32 is retractably disposed within the support 31, and a heat insulation layer is disposed between the support 31 and the sensor.

[0041] For details, please refer to [link / reference]. Figure 3The temperature sensor 32 (such as an NTC thermistor or a miniature K-type thermocouple) is retractably mounted in the internal cavity of the support 31. Specifically, the sensor is mounted on a miniature elastic mechanism (such as a spring or elastic bushing), allowing its sensing end to elastically extend or retract relative to the outer shell of the support 31. When the cookware 100 is placed in position and the support 31 is in contact with the bottom of the cookware, the sensing end of the temperature sensor 32 is pressed tightly against the surface of the cookware 100 under the action of elastic force, ensuring good thermal contact. At the same time, a high-performance heat-insulating material (such as aerogel or ceramic fiber) is filled or wrapped between the temperature sensing element of the temperature sensor 32 and the metal shell of the support 31, forming an effective heat insulation layer. This combined design has dual advantages: the retractable mechanism ensures a stable and reliable heat conduction path between the sensor and the cookware 100; while the heat insulation layer significantly blocks the heat conducted from the high-temperature cookware 100 to the entire support 31 housing, as well as the heat directly radiated from the flame below to the support 31, greatly reducing measurement interference and hysteresis caused by ambient heat radiation and heat conduction of the support body.

[0042] 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.

[0043] Specifically, in combination Figure 1 and Figure 2 As shown, the pot support body 1 typically has three or more (four as illustrated) support plates 3 evenly distributed along the circumference to stably support pots 100 of different sizes and shapes. Temperature sensors 32 can be integrated into one or more (e.g., two or three) of the support plates 3's supports 31. With multiple temperature sensors 32 operating simultaneously, the microcontroller can perform data fusion processing on their readings, such as calculating a weighted average to obtain a more representative overall pot bottom temperature, or monitoring the highest temperature value to prevent localized overheating. This distributed temperature measurement strategy effectively overcomes the random errors in single-point measurements caused by uneven material of the pot 100, uneven heating, uneven pot bottom, or slight tilting, making the final temperature data used for cooking control more robust and reliable.

[0044] Similarly, combining Figure 1 and Figure 2Multiple feet 2 are provided below the pot rack body 1 to ensure stable placement. A weight sensor 21 is integrated at the root of at least one foot 2 (the point of highest stress concentration). By measuring the strain at one or more stress points and based on a pre-calibrated pot rack weight distribution model and mechanical transmission relationship, the microcontroller can accurately invert and calculate the total weight of the pot 100 and food placed on the pot rack. This design modularizes the weighing function in each independent smart pot rack, allowing each burner on a multi-burner stove to be equipped with a smart pot rack with independent and parallel weighing capabilities. This enables synchronous and independent monitoring of the weight of multiple pots 100 cooking simultaneously, perfectly solving the core pain point of traditional stove overall chassis weighing solutions that cannot distinguish and measure the load of a single burner.

[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 LED light rings, a dot matrix screen, or a small buzzer, installed on the pot rack body 1 in a position easily observed by the user (such as the ring edge). The indicator is powered by the pot rack system's circuitry and directly controlled by a microcontroller. As an important human-machine interface, it conveys rich status information to the user: for example, through light colors (green, blue, red) or specific flashing patterns, it visually displays the current cooking stage (such as preheating, boiling, reducing sauce), the system's own status (such as successful wireless connection, low battery warning), or emergency safety alarms (such as dry-burning warning, overload warning). This localized, visual, and instant feedback allows users to quickly and intuitively grasp the cooking process and system status without frequently checking the mobile app or cooktop screen.

[0047] This invention provides a smart pot rack, comprising: a pot rack body 1, a support piece 3 disposed on the pot rack body 1 near the pot 100, and foot pieces 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 pieces 2 are used to support the pot rack body 1; wherein, the support piece 3 is provided with a temperature sensor 32 for collecting temperature information, and the foot pieces 2 are provided with a weight sensor 21 for collecting weight information; the smart pot rack further comprises: a microcontroller and a wireless communication unit, the wireless communication unit being used to establish a communication connection with corresponding linkage devices; the microcontroller being used to control the wireless communication unit to transmit temperature information. Information and / or weight information are sent to the linkage device to enable the linkage device to respond; by integrating temperature and weight sensors 21 into key parts of the pot rack, and combining them with a microcontroller, wireless communication and thermal energy acquisition power supply module, in-situ, real-time and direct measurement of the temperature and weight of the pot 100 is realized under the high temperature environment of the stove, providing reliable real-time cooking data for the stove. It can accurately adjust the dynamic firepower based on the actual state inside the pot and provide safety protection such as anti-dry burning, significantly improving the accuracy, safety and intelligence level of automatic cooking. At the same time, the universal design and self-powered solution provide a practical path for the intelligent upgrade of traditional stoves.

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

[0049] Specifically, the linked devices include at least the main controller of the smart cooktop, and can be extended to the smart range hood, smart kitchen hub, cloud server, and user's mobile terminal (such as mobile APP).

[0050] In this system, the intelligent pot rack acts as the "sensory antennae" and "primary decision-making node" deployed at the forefront. It not only passively collects data but also utilizes a local microcontroller to perform real-time preprocessing and feature extraction of raw temperature and weight signals (such as calculating the rate of temperature change and weight loss), and can make preliminary judgments through preset local logic. Subsequently, these information-rich data packets are efficiently and reliably transmitted via wireless communication units to a collaborative control network composed of interconnected devices.

[0051] The main controller of a smart cooktop is the system's "central decision-making and command hub." It receives data streams from one or more smart pot racks and may combine them with optimized recipes downloaded from the cloud. Based on these real-time, precise physical parameters (such as accurate pot bottom temperature, real-time weight and changing trends of the ingredients in the pot), the main controller can dynamically and precisely adjust actuators such as the gas proportional valve and igniter to achieve millisecond-level precise control over flame size and heating time. This allows for the complete reproduction of complex cooking curves such as "high heat stir-fry - medium heat boiling - low heat reducing sauce - turning off the heat," achieving truly "foolproof" fully automatic programmed cooking.

[0052] Meanwhile, the system has built a deep, cross-device, scenario-based intelligent linkage ecosystem. For example, if the intelligent pot rack detects a sudden temperature rise and enters a high-heat stir-fry state, it can simultaneously notify the stove to adjust the heat and the range hood to activate its strongest suction. When the system determines a risk of dry burning based on a fusion algorithm (combining abnormal temperature and extremely low weight), it can instantly trigger the stove to turn off the heat and simultaneously trigger the pot rack's local indicator to issue an audible and visual alarm, achieving multi-layered safety protection. The entire intelligent cooking system seamlessly combines precise in-situ sensing, reliable wireless data transmission, intelligent local and cloud decision-making, and efficient cross-device execution, achieving a leap from individual device functional intelligence to collaborative intelligence across the entire kitchen scenario. This provides users with an unprecedented safe, convenient, efficient, and highly successful smart cooking experience.

[0053] 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.
