[0003] This application relates to the field of cooktop technology, and in particular to a dry-burning detection device and a cooktop. Background Technology

[0004] In today's society, the safety performance of household stoves has received widespread attention. To improve the safety performance of stoves, most existing stoves have anti-dry-burning functions. These functions involve using a temperature sensor to detect the temperature of the pot bottom and transmitting the signal to the control system. When the pot bottom temperature exceeds the set temperature, the system automatically shuts off the heat, thus preventing dry burning.

[0005] However, existing pot bottom temperature detection devices are generally single-point temperature measurement devices. When faced with different types of pot bottoms, the temperature sensing probe often cannot make full contact with the pot bottom, resulting in poor sensing effect and inability to accurately determine whether the pot bottom has become dry.

[0006] Therefore, a more reliable and adaptable anti-dry-burning detection device is needed. Summary of the Invention

[0007] The technical problem solved by this application is to provide a dry-burning detection device and stove, which can effectively improve the reliability and applicability of detection, thereby improving the accuracy of dry-burning judgment.

[0008] The above-mentioned technical problems are solved by the following technical solutions:

[0009] A dry-burning prevention detection device is installed on a stove and is used to contact a pot placed on the stove. The dry-burning prevention detection device includes:

[0010] The shell, with its top surface used to contact the cookware;

[0011] The circuit board is encapsulated inside the housing and located near the top surface of the housing;

[0012] Multiple temperature detection modules and controllers are integrated and distributed on one side of the circuit board near the top surface, and the controllers are connected to the temperature detection modules.

[0013] The wires are located inside the housing and are electrically connected to the circuit board and the stove, respectively.

[0014] The advantages of the anti-dry-burning detection device described in this application compared to the prior art are as follows:

[0015] By setting multiple temperature detection modules on the circuit board, it can be ensured that at least one temperature probe can fully contact the bottom of the pot, regardless of its shape. This improves the sensing effect and allows for more accurate monitoring of the pot's temperature, ensuring timely detection and control of dry burning, thus effectively preventing dry burning.

[0016] In one embodiment, multiple temperature detection modules are uniformly integrated and distributed on the circuit board.

[0017] In this embodiment, when there are various types of pot bottoms, the temperature detection modules evenly distributed in different locations can specifically monitor temperature changes in different areas, avoiding the problem of poor sensing effect due to insufficient contact of the temperature sensing probe. Therefore, it can improve the safety and performance stability of the stove and effectively prevent dry burning.

[0018] In one embodiment, the housing includes:

[0019] The first hollow cylinder;

[0020] The support platform is welded to one end of the first cylinder to support the circuit board, and a through hole is formed in the center of the bottom of the support platform so that the wires can be electrically connected to the circuit board through the through hole.

[0021] A heat-conducting cover plate is installed on the top of the tray to contact the cookware.

[0022] In this embodiment, a specific structure of the housing is provided to improve the accuracy and sensitivity of temperature detection, while also providing stability, thus ensuring the performance and reliability of the temperature detection module.

[0023] In one embodiment, the distance between the bottom surface of the circuit board and the thermal cover is less than 1.5 mm.

[0024] In this embodiment, by maintaining a small distance between the circuit board and the bottom surface of the heat-conducting cover, the performance of the pot bottom temperature detection device can be further improved, and the user's temperature control needs can be better met.

[0025] In one embodiment, the housing further includes:

[0026] A hollow second cylinder is located outside the first cylinder. One end of the second cylinder is connected to a heat-conducting cover plate, and a heat-insulating gap is formed between the second cylinder and the first cylinder.

[0027] In this embodiment, by further reducing the influence of burner flame radiation through the second cylinder, the data obtained by the temperature detection module can be more accurate and reliable, unaffected by external environmental interference, thus improving the accuracy of the pot bottom temperature data.

[0028] In one embodiment, the heat-conducting cover has a downward flange, and the heat-conducting cover is welded to the outer wall of the support and the outer wall or top of the second cylinder respectively through the flange.

[0029] In this embodiment, the flanged design connects the heat-conducting cover plate to the support platform and the second cylinder, facilitating welding between the heat-conducting cover plate and the support platform, as well as welding the second cylinder to the heat-conducting cover plate. This also improves the welding strength between the heat-conducting cover plate and the support platform and the second cylinder, increasing the stability and reliability of the connection and enhancing the overall appearance quality of the product. Furthermore, it improves the heat insulation effect and ensures the accuracy of temperature data.

[0030] In one embodiment, the anti-dry-burning detection device further includes:

[0031] A spring is installed inside the first cylinder, with one end of the spring connected to the bottom of the support platform;

[0032] A support member, at least a portion of which is housed at the bottom of the first cylinder, and both ends of which are fixedly connected to the stove and the other end of the spring, respectively, to compress the spring when a pot is placed on the stove.

[0033] In this embodiment, through the above-mentioned mechanical structure design, the pushing action of the spring can realize the pushing of the support platform, so that the entire anti-dry burning detection device rises, and then the heat-conducting cover plate contacts the bottom of the pot, thereby realizing the temperature detection of the bottom of the pot. The structure is simple and easy to implement.

[0034] In one embodiment, the controller is connected in parallel with multiple temperature detection modules.

[0035] In this embodiment, by connecting the controller and multiple temperature detection modules in parallel, system redundancy, fault isolation, and security can be achieved, ensuring that the failure of a single module will not affect the normal operation of other modules, thus guaranteeing the stability and reliability of the entire system.

[0036] In one embodiment, the temperature detection module includes:

[0037] Voltage divider resistor; the input terminal of the voltage divider resistor is used to connect the power supply of the stove.

[0038] The thermistor's input terminal is connected to the output terminal of the voltage divider resistor;

[0039] The filter circuit has its input terminal connected to the output terminal of the voltage divider resistor, and its output terminal connected to the controller. The thermistor and the filter circuit are connected to a common ground.

[0040] In this embodiment, the voltage divider resistor is used for voltage division, the thermistor is used for temperature monitoring, and the filter circuit is used for signal filtering. Through the combination of these components, accurate monitoring and stable control of the stove temperature can be achieved, while reducing the impact of noise and interference on the system and ensuring the reliability and stability of the system.

[0059] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0060] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0061] In an exemplary embodiment, as shown in FIG1, this application provides an anti-dry-burning detection device, which is installed on a stove and used to contact a pot placed on the stove. The anti-dry-burning detection device includes a housing 2, a circuit board 4, multiple temperature detection modules 6, a controller (not shown in FIG1), and wires 8. The top surface of the housing 2 is used to contact the pot; the circuit board 4 is encapsulated inside the housing 2 and is close to the top surface of the housing 2; the multiple temperature detection modules 6 and the controller are integrated and distributed on the side of the circuit board 4 near the top surface, and the controller is connected to the temperature detection modules 6; the wires 8 are disposed inside the housing 2, and the wires 8 are electrically connected to the circuit board 4 and the stove respectively.

[0062] The circuit board 4 is a plate-like structure used to support and connect electronic components, and can be made of high-temperature resistant materials such as aluminum nitride or silicon nitride. The temperature detection module 6 is a sensor or device used to measure temperature, monitoring the temperature of the bottom of the cookware, such as a thermocouple, thermistor (such as NTC or PTC), or infrared sensor. The controller can be a microprocessor, microcontroller, or similar programmable logic device that receives and interprets signals from the temperature detection module 6 and makes decisions accordingly, such as cutting off the power to the stove when excessively high temperatures are detected (potentially indicating dry burning) to prevent damage or fire. The wire 8 connects the circuit board 4 and the stove. It can power the circuit board 4 through internal components of the stove, thereby powering the controller and temperature detection module 6. It can also transmit control signals from the controller to the stove to control its power supply. It should be noted that the top surface of the housing 2 refers to the surface of the anti-dry burning detection device in its normal installation state, i.e., the surface in contact with the cookware.

[0063] For example, by setting multiple temperature detection modules 6 on the circuit board 4, with each module 6 positioned slightly differently, the detection range can be increased to ensure that at least one module 6 can make full contact with the bottom of the pot, thus improving the sensing effect. Even when one module cannot make contact with the bottom, the other modules can still perform temperature detection, allowing for more accurate monitoring of the pot's temperature. Therefore, as shown in the pointed-bottom pot 300 in Figure 2 and the uneven pot bottom 500 in Figure 3, even with different pot bottom types, multiple temperature detection modules 6 can solve the problem of poor sensing effect caused by the temperature probe not making full contact with the pot bottom.

[0064] The aforementioned anti-dry-burning detection device, by setting multiple temperature detection modules on the circuit board, ensures that regardless of the shape of the pot bottom, at least one temperature sensing probe can fully contact the pot bottom, thereby improving the sensing effect and enabling more accurate monitoring of the pot's temperature. This ensures timely detection of dry-burning and allows for appropriate control, effectively preventing the occurrence of dry-burning.

[0065] In one exemplary embodiment, as shown in FIG4, multiple temperature detection modules 6 are uniformly integrated and distributed on the circuit board 4.

[0066] For example, when multiple temperature detection modules 6 are uniformly integrated and distributed on the circuit board 4, the overall sensing coverage and uniformity can be further increased. Each temperature detection module 6 is distributed in a different location, allowing for more comprehensive monitoring of the pot's bottom temperature, ensuring coverage of different areas of the entire pot bottom, and improving the accuracy and sensitivity of temperature detection.

[0067] In this embodiment, when there are various types of pot bottoms, the temperature detection modules evenly distributed in different locations can specifically monitor temperature changes in different areas, avoiding the problem of poor sensing effect due to insufficient contact of the temperature sensing probe. Therefore, it can improve the safety and performance stability of the stove and effectively prevent dry burning.

[0068] In an exemplary embodiment, as shown in Figures 1 and 5, the housing 2 includes a hollow first cylinder 22, a support 24, and a heat-conducting cover 26. The support 24 is welded to one end of the first cylinder 22 to support the circuit board 4, and a through hole is formed in the center of the bottom of the support 24 so that the wire 8 can be electrically connected to the circuit board 4 through the through hole; the heat-conducting cover 26 is disposed on the top of the support 24 to contact the cookware.

[0069] The first cylindrical body 22 can be a cube or a cylinder; the support platform 24 can be an annular support platform or a square support platform, and will not be listed here.

[0070] For example, the support platform 24 is welded to one end of the first cylinder 22 as a component supporting the circuit board 4, which can increase the stability and durability of the overall structure, and the through holes can facilitate the electrical connection between the wires 8 and the circuit board 4. The heat-conducting cover 26 is set on the top of the support platform 24, which can make it easier to contact the pot, improve the ease of operation, and the direct contact between the heat-conducting cover 26 and the pot can effectively conduct the temperature of the bottom of the pot to the temperature detection module 6, making the temperature detection more accurate and sensitive.

[0071] In this embodiment, a specific structure of the housing is provided to improve the accuracy and sensitivity of temperature detection, while also providing stability, thus ensuring the performance and reliability of the temperature detection module.

[0072] In one exemplary embodiment, the distance between the bottom surfaces of the circuit board and the thermally conductive cover is less than 1.5 mm.

[0073] For example, when the distance between the circuit board 4 and the bottom surface of the heat-conducting cover 26 is less than 1.5 mm, the distance between the circuit board 4 and the bottom surface of the heat-conducting cover 26 is very small, which can effectively reduce thermal resistance, increase heat conduction efficiency, reduce heat loss and diffusion, reduce heat delay transmission, and enable the heat-conducting cover 26 to sense the temperature change of the bottom of the pot more quickly and accurately.

[0074] In this embodiment, by maintaining a small distance between the circuit board 4 and the bottom surface of the heat-conducting cover 26, the performance of the pot bottom temperature detection device can be further improved, and the user's temperature control needs can be better met.

[0075] In an exemplary embodiment, as shown in Figures 1, 5, and 6, the housing 2 further includes a hollow second cylinder 28. The second cylinder 28 is disposed outside the first cylinder 22, one end of the second cylinder 28 is connected to the heat-conducting cover plate 26, and a heat-insulating gap is formed between the second cylinder 28 and the first cylinder 22.

[0076] The second cylinder 28 can also refer to a cube or a cylinder.

[0077] For example, the heat insulation gap formed between the second cylinder 28 and the first cylinder 22 can effectively reduce the influence of the radiant heat conduction of the burner flame to the temperature detection module 6, and reduce the interference of external heat sources on temperature detection.

[0078] In this embodiment, by further reducing the influence of burner flame radiation through the second cylinder, the data obtained by the temperature detection module can be more accurate and reliable, unaffected by external environmental interference, thus improving the accuracy of the pot bottom temperature data.

[0079] In an exemplary embodiment, as shown in Figures 1 and 5, the heat-conducting cover 26 has a downward flange 262, and the heat-conducting cover 26 is welded to the outer wall of the support 24 and the outer wall or top of the second cylinder 28 respectively through the flange 262.

[0080] For example, the flange 262 design can increase the connection area between the heat-conducting cover 26 and the outer wall of the support 24 and the outer wall of the second cylinder 28, improving welding strength, increasing the stability and reliability of the connection, reducing the risk of component loosening or detachment, and extending product lifespan. The flange 262 design also makes the connection between the heat-conducting cover 26 and the support 24 and the second cylinder 28 more compact and neat, with higher aesthetic appeal, improving the overall appearance quality of the product and enhancing the user's aesthetic experience. In addition, the flange 262 design can form a certain air insulation layer, reducing the impact of external heat sources on the temperature detection module 6, improving the insulation effect, further reducing interference from external environmental factors on temperature detection, and ensuring the accuracy of temperature data.

[0081] In this embodiment, the flanged design connects the heat-conducting cover plate to the support platform and the second cylinder, facilitating welding between the heat-conducting cover plate and the support platform, as well as welding the second cylinder to the heat-conducting cover plate. This also improves the welding strength between the heat-conducting cover plate and the support platform and the second cylinder, increasing the stability and reliability of the connection and enhancing the overall appearance quality of the product. Furthermore, it improves the heat insulation effect and ensures the accuracy of temperature data.

[0082] In an exemplary embodiment, as shown in Figures 1, 5, and 6, the anti-dry-burning detection device further includes a spring 10 and a support member 12. The spring 10 is disposed inside the first cylinder 22, with one end of the spring 10 connected to the bottom of the support platform 24; at least a portion of the support member 12 is housed at the bottom of the first cylinder 22, and both ends of the support member 12 are fixedly connected to the stove and the other end of the spring 10, respectively, so as to compress the spring 10 when a pot is placed on the stove.

[0083] For example, the support member 12 in the anti-dry-burning detection device is fixedly connected to the stove and the spring 10. The spring 10 is also fixedly connected to the bottom of the support platform 24. The support member 12 can slide freely within the first cylinder 22. Therefore, when the pot is placed on the stove, the spring 10 is compressed under the weight of the pot. Under the reaction force of the spring 10, the anti-dry-burning detection device as a whole makes the heat-conducting cover 26 contact the bottom of the pot, thereby realizing the temperature detection of the bottom of the pot through the temperature detection module 6. When the pot is removed from the stove, the anti-dry-burning detection device returns to its initial position under the support of the support member 12 and the spring 10.

[0084] In this embodiment, through the above-mentioned mechanical structure design, the pushing action of the spring can realize the pushing of the support platform, so that the entire anti-dry burning detection device rises, and then the heat-conducting cover plate contacts the bottom of the pot, thereby realizing the temperature detection of the bottom of the pot. The structure is simple and easy to implement.

[0085] In one exemplary embodiment, as shown in FIG7, the controller MCU is connected in parallel with multiple temperature detection modules 6.

[0086] For example, by connecting multiple temperature detection modules 6 in parallel with the controller MCU, system redundancy can be achieved. Even if one module fails or is damaged, the other normally functioning modules can continue to monitor and provide temperature data, ensuring system stability and reliability. When one temperature detection module 6 fails, since each temperature detection module 6 is independent, the controller MCU can identify the faulty module by detecting data from other modules and isolate its impact, thereby ensuring the normal operation of the entire system. Simultaneously, connecting multiple temperature detection modules 6 in parallel can improve system safety. For instance, when one module malfunctions, the other normally functioning modules can still detect and respond promptly, preventing safety issues caused by temperature anomalies.

[0087] In this embodiment, by connecting the controller and multiple temperature detection modules in parallel, system redundancy, fault isolation, and security can be achieved, ensuring that the failure of a single module will not affect the normal operation of other modules, thus guaranteeing the stability and reliability of the entire system.

[0088] In an exemplary embodiment, as shown in FIG7, the temperature detection module 6 includes a voltage divider resistor, a thermistor, and a filter circuit. The input terminal of the voltage divider resistor is used to connect to the power supply of the stove; the input terminal of the thermistor is connected to the output terminal of the voltage divider resistor; the input terminal of the filter circuit is connected to the output terminal of the voltage divider resistor, and the output terminal of the filter circuit is connected to the controller. The thermistor and the filter circuit are connected to a common ground.

[0089] For example, as shown in Figure 7, each temperature detection module 6 includes a voltage divider resistor, a thermistor, and a filter circuit. For instance, taking one temperature detection module 6 as an example, it includes a voltage divider resistor R5, a thermistor NTC3, and a filter capacitor composed of a resistor R7 and a capacitor C5. The voltage divider resistor divides the input voltage to obtain a lower output voltage, which is used to provide the thermistor as its input signal. The thermistor is a temperature-sensitive resistor whose resistance changes with temperature. The thermistor can be used to monitor the temperature of the stove, thereby detecting the temperature at different locations on the bottom of the pot. The filter circuit filters the signal output from the voltage divider resistor, removing noise and interference to obtain a stable temperature signal, which is then transmitted to the controller for processing.

[0090] In this embodiment, the voltage divider resistor is used for voltage division, the thermistor is used for temperature monitoring, and the filter circuit is used for signal filtering. Through the combination of these components, accurate monitoring and stable control of the stove temperature can be achieved, while reducing the impact of noise and interference on the system and ensuring the reliability and stability of the system.

[0091] In an exemplary embodiment, as shown in FIG7, the anti-dry-burning detection device further includes a power supply circuit 14. The specific circuit structure of the power supply circuit 14, and its connection relationship with the controller and temperature detection module 6, can be directly understood by those skilled in the art from the circuit diagram shown in FIG7, and will not be elaborated further here. It should be noted that the power supply circuit 14 shown in FIG7 is merely an example and is not intended to be limiting.

[0092] For example, the power supply circuit 14 is used to provide a stable power supply for the entire anti-dry-burning testing equipment, ensuring that each module works normally. The power supply circuit 14 may include components such as power management circuits and voltage regulator circuits, used to convert and stabilize the power supply voltage to a suitable operating voltage for each module, and to provide sufficient current to support the normal operation of each component.

[0093] In this embodiment, a stable power supply is provided to the anti-dry-burning detection equipment through the power supply circuit, ensuring the normal operation of each module, ensuring the stable power supply of the system, and improving the reliability and stability of the entire system.

[0094] In one exemplary embodiment, this application also provides a cooktop, which includes a cooktop body and the anti-dry-burning detection device described in the above embodiment.

[0095] In this embodiment, the anti-dry-burning detection device enables accurate monitoring and stable control of the temperature of the pot placed on the stove, thereby improving the user experience.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
