Description

Technical Field

[0001] This invention relates to the field of cooking appliance technology, and in particular to a smart pot and a stove with a smokeless smart temperature control pot. Background Technology

[0002] In traditional cooking, especially Chinese cooking, most existing methods lack automatic temperature control. Users need to manually adjust the heat based on experience to control the pot's temperature, causing significant inconvenience. This requires manual adjustment of the heater (induction cooker, gas stove, etc.), which leads to the following problems:

[0003] First, the temperature control is inaccurate—it relies on the user's subjective judgment and is difficult to accurately maintain a specific temperature range;

[0004] Secondly, the problem of cooking fumes—when the temperature of cooking oil in the pan exceeds 200℃, it will produce a large amount of harmful fumes. These fumes not only pollute the kitchen environment but also contain a variety of harmful substances, which can easily pose a threat to health.

[0005] Although there are some cookwares with temperature sensors or smart cookwares that can display the temperature of the pot, these cookwares can only display the temperature and do not have signal functions. Furthermore, their temperature detection is inaccurate, and the heater needs to be manually adjusted (for induction cookers, gas stoves, etc.). They fail to form a closed-loop control system with the cookware and cannot meet the needs of modern users. Summary of the Invention

[0006] (a) Technical problems that need to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an intelligent pot and a stove with an oil-free intelligent temperature control pot. It can automatically collect temperature data for intelligent control, which is beneficial for automatically controlling the stove's working status and accurately controlling the temperature to prevent the generation of oil fumes. At the same time, it can also achieve energy-saving effects, solving the problems of inaccurate temperature control, excessive oil fumes, and energy waste in traditional cooking.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] A smart pot includes a pot body and a handle disposed on the pot body. The pot body is provided with a detection element for detecting the temperature of the center area of ​​the bottom of the pot. A temperature control switch and a transmitting device are disposed on the handle near the connection point with the pot body. The transmitting device is connected to the detection element and the temperature control switch respectively. A first controller is disposed on the handle. The first controller is connected to the detection element, the temperature control switch and the transmitting device respectively.

[0011] The detection device has a preset first threshold T1. When the detection device senses that the temperature at the center of the pot bottom is higher or lower than the first threshold T1, the first controller will send a command through the transmitting device to activate high temperature protection or temperature maintenance mode. The temperature control switch has a preset second threshold T2. When the temperature control switch senses that the temperature at the handle is lower than the second threshold T2, the temperature control switch is turned off, and the first controller enters a no-power standby state through the transmitting device.

[0012] Preferably, the detection element is tightly attached to the bottom of the pot body, and the detection element is a thermocouple sensor. The thermocouple sensor is directly attached to the center area of ​​the bottom of the pot, the measurement range of the thermocouple sensor is -50℃ to +1300℃, and the accuracy of the thermocouple sensor is ±1℃.

[0013] Preferably, the thermocouple sensor is a type K or type J thermocouple.

[0014] Preferably, the pot body is made of a material with uniform heat conduction.

[0015] Preferably, the handle has a cavity, in which the first controller is installed, and a maintenance cover is provided on the cavity. The power supply is installed in the cavity and is used to provide power to the detection element, temperature control switch, transmitting device and the first controller.

[0016] Preferably, the power source is a lithium battery, and a charging interface is provided on the end face of the handle, the charging interface being connected to the battery.

[0017] Preferably, the charging interface is a USB interface.

[0018] Preferably, the temperature control switch is a bimetallic strip or electronic temperature switch.

[0023] Preferably, the receiving device is an infrared receiving device, and the infrared receiving device is located below the transmitting device in the smart pot, so that the infrared receiving device and the transmitting device are arranged correspondingly.

[0024] (III) The technical effects to be achieved

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] Firstly, the pot body of this invention is equipped with a detection element for detecting the temperature of the central area of ​​the pot bottom. A temperature control switch and a transmitting device are provided on the handle near the connection point with the pot body. The transmitting device is connected to the detection element and the temperature control switch respectively. A first controller is provided on the handle. The first controller is connected to the detection element, the temperature control switch and the transmitting device respectively. This type of pot, while maintaining its structure, can collect data at different temperatures, which is beneficial for subsequent intelligent control. It is also more conducive to automatically controlling the working status of the stove and accurately controlling the temperature to prevent the generation of oil fumes, while also achieving energy-saving effects.

[0027] Secondly, the detection component of this invention has a preset first threshold T1. When the detection component senses that the temperature at the center of the pot bottom is higher or lower than the first threshold T1, the first controller will send an instruction through the transmitting device to activate high-temperature protection or temperature maintenance mode. The temperature control switch has a preset second threshold T2. When the temperature control switch senses that the temperature at the handle is lower than the second threshold T2, the temperature control switch is turned off, and the first controller enters a power-free standby state through the transmitting device. This allows for automatic control of the stove's working state and precise temperature control to prevent the generation of oil fumes, while also achieving energy-saving effects and better meeting usage needs.

[0028] Thirdly, the present invention includes a stove platform, on which a receiving device and a second controller are provided, which are connected to the smart pot described above. The receiving device is connected to the second controller. This facilitates automatic control of the stove's working status and precise temperature control to prevent the generation of oil fumes. At the same time, it can achieve energy-saving effects and solve the problems of inaccurate temperature control, excessive oil fumes, and energy waste in traditional cooking.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0043] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A smart pot includes a pot body 1 and a handle 2 mounted on the pot body 1. The pot body 1 has a sensor 3 for detecting the temperature of the center area of ​​the pot bottom. A temperature control switch 4 and a transmitter 5 are mounted on the handle 2 near the connection point with the pot body 1. The transmitter 5 is connected to the sensor 3 and the temperature control switch 4. A first controller 6 is mounted on the handle 2 and is connected to the sensor 3, the temperature control switch 4, and the transmitter 5. The sensor 3 has a preset first threshold T1. When the sensor 3 detects that the temperature at the center of the pot bottom is higher or lower than the first threshold T1, the first controller 6 sends a command through the transmitter 5 to activate high-temperature protection or a temperature maintenance mode. The temperature control switch 4 has a preset second threshold T2. When the temperature control switch 4 detects that the temperature at the handle 2 is lower than the second threshold T2, the temperature control switch 4 is deactivated, and the first controller 6 enters a no-power standby state via the transmitter 5.

[0044] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the detection element 3 is tightly fitted to the bottom of the pot body 1. The detection element 3 uses a thermocouple sensor, which is directly attached to the center area of ​​the pot bottom. The measurement range is -50℃ to +1300℃, with an accuracy of ±1℃. This design is advantageous for accurately detecting the pot bottom temperature. Furthermore, the thermocouple sensor is either type K or type J, offering a variety of options. Additionally, the thermocouple sensor is embedded in the bottom of the pot body 1, ensuring a tight fit between the sensor and the pot bottom, guaranteeing accurate temperature detection and rapid response.

[0045] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 1 and Figure 2 As shown, the pot body 1 is made of a material with uniform heat conduction, which is more conducive to heat conduction and also more conducive to temperature measurement by the detection component 3.

[0046] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 1 and Figure 2 As shown, the handle 2 has a chamber containing a first controller 6. A maintenance cover 21 is provided on the chamber, and a power supply 7 is also installed within it. The power supply 7 provides power to the detection element 3, temperature control switch 4, transmitting device 5, and the first controller 6. Further, the power supply 7 is a battery, preferably a lithium battery. A charging interface 22 is provided on the end face of the handle 2, which connects to the battery. This design facilitates continuous charging and use. Furthermore, the charging interface is a USB interface for user convenience.

[0047] Example 5: This can be described based on Example 1, Example 2, Example 3, or Example 4, such as... Figure 3 and Figure 5 As shown, the temperature control switch 4 is a bimetallic strip or electronic temperature switch, which not only offers a variety of types and options, but is also easy to implement and facilitates disconnection.

[0048] Example 6: This can be described based on Example 1, Example 2, Example 3, Example 4, or Example 5, such as... Figure 3 , Figure 4 and Figure 5 As shown, the transmitting device 5 is vertically downward on the handle 2, which is more conducive to signal transmission. Furthermore, the transmitting device 5 is an infrared transmitter with an embedded encoding chip, which helps reduce signal interference.

[0049] Example 7: This can be explained based on Example 1, Example 2, Example 3, Example 4, Example 5, or Example 6. The first set threshold T1 is preferably 200°C. Since temperatures exceeding 200°C will produce a large amount of harmful fumes, which not only pollute the kitchen environment but also contain a variety of harmful substances, this can easily pose a threat to health. Therefore, the first set threshold T1 is used to enable the system to be in a high-temperature protection or temperature maintenance mode. The second set threshold T2 is preferably 60°C. This setting is beneficial for controlling the system to enter a no-power standby state.

[0050] Example 8: This can be described based on Example 1, Example 2, Example 3, Example 4, Example 5, Example 6, or Example 7, such as... Figure 6 , Figure 7 and Figure 8As shown, the present invention also provides a stove with a smokeless intelligent temperature-controlled pot, including a stove platform 10, a burner combustion port 101 fixedly opened on the end face of the stove platform 10, a kitchen utensil rack 102 arranged on the stove platform 101 corresponding to the burner combustion port 101, a rotary ignition knob 103 installed on the end face of the stove platform 10 near the burner combustion port 101, a burner 104 arranged inside the burner combustion port 101, the burner 104 being used for gas combustion, a receiving device 30 and a second controller 40 connected to the intelligent pot 20 as described above are arranged on the stove platform 101, the receiving device 30 being connected to the second controller 40, the second controller 40 being used to control the gas status of the stove, and the intelligent pot 20 as described above being placed on the kitchen utensil rack 102. Further explanation: The receiving device 30 uses an infrared receiving device, which is easy to implement. The infrared receiving device is located below the transmitting device 5 in the smart pot 20, ensuring a corresponding arrangement between the infrared receiving device and the transmitting device 5. This facilitates better reception of the signal from the transmitting device 5 and ensures smooth communication between the transmitting device 5 and the infrared receiving device on the stovetop 10. The infrared receiving device is located below the stovetop 10 (below the stove panel). Both the infrared transmitting and receiving devices use coded signals to resist interference. The infrared receiving device on the stovetop 10 receives the signal from the transmitting device 5 in the smart pot 20 and transmits the decoded signal to the second controller 40. The second controller 40, based on a preset algorithm and user settings, controls the working state of the burner 12 through a fire control device. This allows for automatic control of the stovetop's working state according to the temperature of the smart pot 20, preventing oil fumes and achieving energy savings. In this invention, a bistable solenoid valve 50 (e.g., ...) is also installed on the stovetop 10. Figure 8 As shown in the figure, by providing a reverse pulse current to the bistable solenoid valve 50, the pulse current is only used when the gas is turned off or on, thus saving a lot of power.

[0051] When the thermocouple sensor detects that the temperature of the bottom of the pot 1 is higher than the first set threshold T1 (preferably 200°C), the infrared transmitter emits a first signal, which is received by the infrared receiver. Since the infrared transmitters are connected, the second controller 40 then controls the stove 10 to shut off the flame. When the thermocouple sensor detects that the temperature of the bottom of the pot 1 is lower than the first set threshold T1 (preferably 200°C), the stove is reignited to maintain the temperature within the set range. By setting the first set threshold T1 below the common smoke point of cooking oil (e.g., 200°C) and coordinating precise re-ignition control, the oil temperature is stabilized below the smoke point (anti-smoke control strategy, such as...). Figure 7(As shown). The workflow of the anti-fume control mode is as follows: The stove system starts working, and the thermocouple sensor detects the bottom temperature of the pot 1 in real time. It determines whether the detected temperature is higher than the first set threshold T1 (set upper limit), such as 200℃ or 199℃. If so, the infrared receiver receives the first signal emitted by the infrared transmitter. Since the infrared transmitters are connected, the second controller 40 quickly shuts off the fire. It then determines whether the detected temperature is lower than the first set threshold T1 (set lower limit), such as 200℃ or 199℃. If so, the infrared receiver receives the first signal emitted by the infrared transmitter. Since the infrared transmitters are connected, the second controller 40 quickly ignites the stove to heat the smart pot 20 placed on the cookware rack 102 and continuously monitors it until cooking is finished. This achieves high-temperature protection and temperature maintenance mode.

[0052] When the temperature control switch 4 detects that the temperature at the handle 2 is lower than the second set threshold T2 (preferably 60℃) for a predetermined time (e.g., 3-5 minutes), the temperature control switch 4 disconnects and emits a second signal through the infrared transmitter. The infrared receiver receives the second signal emitted by the infrared transmitter. Since the infrared transmitters are connected, the second controller 40 then controls the cooktop 10 to enter a power-free standby state. This is beneficial for achieving an energy-saving standby mode. The workflow of the energy-saving standby mode is as follows: The temperature control switch 4 can detect the temperature at the handle 2 near the connection point with the pot body 1 in real time and determine whether the temperature is lower than the second set threshold T2, such as 60℃. If so, it determines whether the low temperature state lasts for more than three minutes. If so, the temperature control switch 4 disconnects, and the battery forms an open circuit, thus saving power. In the standby state, it continuously monitors the temperature change at the handle 2 near the connection point with the pot body 1 and determines whether the temperature rises back to above 60℃ or user operation is detected. If so, it exits the standby state and resumes normal operation.

[0053] This invention can automatically control the working status of the stove, precisely control the temperature to prevent the generation of oil fumes, and achieve energy saving. It solves the problems of inaccurate temperature control, excessive oil fumes, and energy waste in traditional cooking, and can achieve the following objectives:

[0054] Precise temperature control and elimination of oil fumes—by setting the first set threshold T1 (high temperature protection threshold T1) below the oil smoke point (e.g., 200℃) and combining it with rapid response control, the oil temperature is always kept below the oil fume generation temperature, reducing oil fumes at the source;

[0055] Intelligent energy saving—When the temperature of the handle 2 of the smart pot 20, which is close to the connection point with the pot body 1, is lower than the second set threshold T2 (such as below 60°C) and lasts for a period of time (generally set to three minutes), it indicates that the cooking may be in a break or end state. The system automatically enters standby mode, reducing energy waste and helping to solve the problem of energy waste. It also avoids the problem of not being able to turn down the heat in time during a break or after cooking.

[0056] Enhanced safety – Prevents the Smart Pot 20 from dry burning or overheating of oil, reducing the risk of fire.

[0057] Easy to operate—achieving automated cooking with "set and leave it alone," reducing the burden of user supervision.

[0058] High compatibility—The smart pot 20 and the cooktop 10 communicate wirelessly via infrared receiver and transmitter, eliminating the need for physical connection and making it easy to adapt to different cooktops.

[0059] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology. The controller, temperature control switch and internal components all adopt conventional models in the existing technology, and their internal structure belongs to the existing technology structure. Workers can complete normal operation by referring to the existing technical manual. In addition, the circuit connection adopts conventional connection methods in the existing technology, and will not be described in detail here.

Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this invention, or equivalent structural or procedural transformations made using the content of this specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this invention.
