Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and more specifically, to a gas stove. Background Technology With the improvement of living standards and the development of technology, kitchen cooking is moving towards intelligence and automation. As the core equipment of a smart kitchen, the goal of smart cooktops is to achieve precise temperature control and a safe cooking process, thereby liberating users and enhancing the cooking experience.

[0002] Currently, the intelligent development of cooktops relies heavily on accurate temperature detection, with the anti-dry-burning function being the core of ensuring safety and improving cooking results.

[0003] This function is generally achieved through a temperature sensor (such as an NTC thermistor) on the bottom of the pot, and its detection accuracy directly determines the reliability of safety protection and the feasibility of intelligent cooking. However, in practical applications, the detection accuracy of this sensor is easily affected by the rise in its own temperature and ambient temperature.

[0004] Specifically, the probe generates a self-heating effect during continuous operation, causing its measured value to deviate from the actual temperature of the cookware. Simultaneously, the high-temperature flame from the stove and the thermal radiation environment created by the gas directly heat the probe itself, resulting in significant temperature signal distortion. These factors combined make it difficult for the system to accurately distinguish between normal vigorous cooking (such as stir-frying) and a true dangerous state of dry burning.

[0005] To avoid false alarms, current solutions often resort to conservative trigger thresholds, which introduce safety hazards due to response delays when actual dry burning occurs. This fundamental precision deficiency not only restricts the reliability of anti-dry burning functions but also makes it difficult to stably implement intelligent cooking programs requiring precise temperature control (such as sous-vide cooking and constant-temperature frying), becoming a key bottleneck hindering further breakthroughs in intelligent cooktop technology. Therefore, an innovative technical solution that can effectively compensate for or eliminate such temperature interference is urgently needed. Summary of the Invention

[0006] The present invention includes, for example, providing a gas stove that can create a localized, controllable low-temperature working environment for a temperature sensor, thereby isolating or reducing environmental thermal interference.

[0007] The embodiments of the present invention can be implemented as follows: In a first aspect, the present invention provides a gas stove, comprising: Burner head, temperature sensor and blower; The temperature sensor is disposed on the burner head and extends above the burner head; the temperature sensor is configured to detect the temperature of the bottom of a pot placed on the burner head. The temperature sensor is used in conjunction with the blower, which is configured to increase the gas flow rate near the outer wall of the temperature sensor to remove heat from the surface of the temperature sensor, thereby achieving rapid cooling of the temperature sensor.

[0008] This solution increases the gas flow near the outer wall of the temperature sensor using a blower, achieving rapid cooling of the sensor. On one hand, it intelligently controls the blower's speed according to different cooking environments to lower the ambient temperature around the sensor. Simultaneously, controlling the blower's airflow also supplements the gas stove with secondary air, reducing smoke and improving thermal efficiency. This significantly enhances the detection accuracy of intelligent stoves, addressing the issue of low thermal efficiency and improving user satisfaction. Furthermore, for different cooking modes, the blower can be selectively turned on and off, or its speed and airflow adjusted, to increase or decrease the sensitivity of the temperature sensor, thus adapting to the varying accuracy requirements of the anti-dry-burning function under different cooking modes.

[0009] In an optional embodiment, a diversion duct is further included. One end of the diversion duct is connected to the air outlet of the blower, and the other end of the diversion duct faces the temperature sensor. The diversion duct is configured to guide the airflow from the blower outlet toward the temperature sensor to achieve rapid cooling of the temperature sensor. In this way, the cooling airflow generated by the blower is precisely guided to the area around the temperature sensor through the diversion duct, forming an air curtain that effectively removes the heat accumulated in and around the sensor body. This achieves active air cooling of the sensor, thereby improving the technical problem in the prior art where the detection accuracy of the temperature sensor decreases due to flame radiation and high-temperature gas baking. This ensures that the detected value always accurately reflects the temperature of the pot bottom, thus greatly improving the accuracy and reliability of the anti-dry-burning function and reducing false alarms.

[0010] In an optional embodiment, an air outlet box is further included, in which the air duct is disposed; one end of the air duct passes through the air outlet box to form an air outlet box inlet, and the other end of the air duct passes through the air outlet box to form an air outlet box outlet; the air outlet of the blower is connected to the air outlet box inlet, and the air outlet box outlet faces the bottom of the temperature sensor. The air outlet box ensures the stable installation of the air duct and also ensures good cooperation between the blower and the temperature sensor.

[0011] In an optional embodiment, the air duct includes a first straight section and a second straight section with an included angle. The first straight section is connected to the blower, and the second straight section is arranged collinearly with the temperature sensor. Thus, the cooling airflow direction at the blower's outlet changes direction after passing through the air duct, ensuring that the cooling airflow effectively and efficiently cools the temperature sensor.

[0012] In an optional embodiment, the air outlet box further includes a mating through hole; the temperature sensor includes a body and a signal line connected to each other, the signal line extending through the mating through hole to the bottom of the air outlet box. Thus, the air outlet box can also serve as the mounting path for the temperature sensor, making the structure of the air outlet box more compact.

[0013] In an optional embodiment, a probe holder is also included, to which the temperature-sensing probe is connected; the probe holder has a through vent hole facing the outer wall of the temperature-sensing probe; and the airflow duct is connected to the vent hole. Here, the probe holder ensures the stability of the temperature-sensing probe and continues to guide the cooling airflow from the blower towards the outer wall of the temperature-sensing probe, thus ensuring cooling of the probe.

[0014] In an optional embodiment, the probe holder has a through mounting hole at its center, and the vent is arranged radially outward from the mounting hole; the temperature sensor probe can pass through the mounting hole. This ensures stable and efficient operation of the temperature sensor probe, while also improving the compactness of the gas stove.

[0015] In an optional embodiment, a burner is also included, the burner having a central through-hole, the temperature sensing probe passing through the central through-hole and extending to the top of the burner; the airflow from the outlet of the blower can be guided to the central through-hole; The burner has a through-hole at the top, which connects to the central through-hole. Through the cooperation of the blower and the through-hole, the cooling airflow from the blower outlet can rapidly cool the temperature sensor while also guiding a portion of the cooling airflow to the burner to replenish secondary air.

[0016] In an optional embodiment, the burner includes a copper core, and the air supply port is arranged circumferentially along the copper core.

[0017] In an optional embodiment, there are multiple air supply holes, which are evenly distributed circumferentially on the copper core. This arrangement allows the gas appliance to receive more secondary air, thereby promoting complete combustion of the gas and achieving the dual effect of reducing flue gas (such as carbon monoxide) emissions and improving the thermal efficiency of the stove.

[0018] The beneficial effects of the embodiments of the present invention include, for example: The gas stove in this design includes a burner, a temperature sensor, and a blower. The blower increases the gas flow rate near the outer wall of the temperature sensor, carrying away heat from its surface and rapidly cooling it. This design creates a localized, controllable low-temperature operating environment for the temperature sensor, isolating or reducing environmental thermal interference. This adjusts the detection accuracy of the temperature sensor, thereby ensuring the stability and reliability of the gas stove's anti-dry-burning function.

[0019] On one hand, during the stove's operation, the control system analyzes the current cooking mode (such as stir-frying or simmering) or the rising trend of the temperature sensor's temperature in real time or according to a preset program, and intelligently adjusts the speed of the blower accordingly. When the system determines that the ambient temperature around the sensor is high and there is a risk of thermal interference, it activates the blower to deliver cooling airflow. This airflow is precisely guided to the area around the temperature sensor, forming an air curtain that effectively removes the heat accumulated in and around the sensor, achieving active air cooling. This significantly suppresses the sensor's self-heating effect and the influence of ambient heat radiation, ensuring that its detection value always accurately reflects the temperature of the pot bottom, thereby greatly improving the accuracy and reliability of the anti-dry-burning function and reducing false alarms. Simultaneously, for different cooking modes, the system selectively turns the blower on and off, or adjusts the blower's speed and airflow, to increase or decrease the sensitivity of the temperature sensor, thus adapting to the different accuracy requirements of the anti-dry-burning function under different cooking modes.

[0020] On the other hand, this solution cleverly combines the functions of "heat dissipation" and "combustion assistance" into one. After cooling the probe, the airflow blown by the blower can be further guided to the vicinity of the burner, serving as secondary air to supplement the combustion process. By precisely controlling the airflow, not only are the heat dissipation requirements of the probe met, but it also helps the gas to burn completely, achieving the dual effect of reducing flue gas (such as carbon monoxide) emissions and improving the thermal efficiency of the stove.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0028] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0029] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a gas stove including a burner 620, a temperature sensor 100, and a blower 200; A temperature sensor 100 is disposed on the burner head 620 and extends above the burner head 620; the temperature sensor 100 is configured to detect the temperature of the bottom of a pot placed on the burner head 620. The temperature sensor 100 is used in conjunction with the blower 200, which is configured to increase the gas flow rate near the outer wall of the temperature sensor 100 to remove heat from the surface of the temperature sensor 100, thereby achieving rapid cooling of the temperature sensor 100.

[0031] It should be noted that the temperature sensor 100 provides real-time temperature data to the gas stove controller by checking the temperature of the bottom of the pot on the burner 620. The controller then shuts down the corresponding burner 620 according to a preset program, thereby protecting the pot from dry burning.

[0032] In this design, the blower 200 of the gas stove is used to increase the gas flow rate near the outer wall of the temperature sensor 100, thereby removing heat from the surface of the temperature sensor 100 and achieving rapid cooling of the temperature sensor 100. This setup creates a localized, controllable low-temperature working environment for the temperature sensor 100, thus isolating or reducing environmental thermal interference. This adjusts the detection accuracy of the temperature sensor 100, thereby ensuring the stability and reliability of the gas stove's anti-dry-burning function.

[0033] On the one hand, during the operation of the stove, the control system analyzes the current cooking mode (such as stir-frying or simmering) or the rising trend of the temperature of the temperature sensor 100 in real time or according to a preset program, and intelligently adjusts the speed of the blower 200 accordingly. When the system determines that the ambient temperature of the sensor is high and there is a risk of thermal interference, it starts the blower 200 to deliver cooling airflow. This airflow is precisely guided to the area around the temperature sensor 100, forming an air curtain that effectively removes the heat accumulated in and around the sensor, achieving active air cooling of the sensor. This significantly suppresses the self-heating effect of the sensor and the influence of ambient heat radiation, ensuring that its detection value always accurately reflects the temperature of the pot bottom, thereby greatly improving the accuracy and reliability of the anti-dry-burning function and reducing false alarms. At the same time, for different cooking modes, the system selectively turns the blower 200 on and off, or adjusts the speed and volume of the blower 200, to increase or decrease the sensitivity of the temperature sensor 100, thus adapting to the different requirements for the accuracy of the anti-dry-burning function under different cooking modes.

[0034] On the other hand, this solution cleverly combines the functions of "heat dissipation" and "combustion assistance" into one. After cooling the probe, the airflow blown by the blower 200 can be further guided to the vicinity of the burner 600, serving as secondary air to supplement the combustion process. By precisely controlling the airflow, not only are the heat dissipation requirements of the probe met, but it also helps the gas to burn completely, achieving the dual effect of reducing flue gas (such as carbon monoxide) emissions and improving the thermal efficiency of the stove.

[0035] Please continue reading. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 To learn more about the structural details of the gas stove.

[0036] In an optional embodiment, the gas stove further includes a diversion duct 300, one end of which is connected to the air outlet 210 of the blower 200, and the other end of which faces the temperature sensor 100. The diversion duct 300 is configured to guide the airflow from the air outlet 210 of the blower 200 toward the temperature sensor 100 to achieve rapid cooling of the temperature sensor 100.

[0037] In this way, the cooling airflow generated by the blower 200 through the air duct 300 is precisely guided to the area around the temperature sensor 100, forming an air curtain that effectively removes the heat accumulated in and around the sensor body. This achieves active air cooling of the sensor, thereby improving the technical problem in the prior art where the temperature sensor 100 suffers from decreased detection accuracy due to flame radiation and high-temperature gas baking. This ensures that the detection value always accurately reflects the temperature of the bottom of the pot, thus greatly improving the accuracy and reliability of the anti-dry burning function and reducing false alarms.

[0038] from Figures 1 to 5 It can also be seen that, in an optional embodiment, the gas stove further includes an air outlet box 400, and a diversion duct 300 is disposed in the air outlet box 400; one end of the diversion duct 300 passes through the air outlet box 400 to form an air outlet box 410, and the other end of the diversion duct 300 passes through the air outlet box 400 to form an air outlet box 420; the air outlet 210 of the blower 200 is connected to the air outlet box 410, and the air outlet box 420 is directly opposite the bottom of the temperature sensor 100. The setting of the air outlet box 400 can ensure the stable setting of the diversion duct 300, and at the same time, it can also ensure good cooperation between the blower 200 and the temperature sensor 100.

[0039] As can be seen from the figure, there are two bellows outlets 420 in this embodiment, and the cross-sections of the two bellows outlets 420 are both semi-circular.

[0040] from Figure 3 As can be seen from the optional embodiment, the airflow duct 300 includes a first straight section 310 and a second straight section 320 with an included angle. The first straight section 310 is connected to the blower 200, and the second straight section 320 is arranged collinearly with the temperature sensor 100. In this way, the cooling airflow direction of the blower 200's outlet 210 is changed after passing through the airflow duct 300, so that it can be directly facing the temperature sensor 100, thereby ensuring that the cooling airflow cools the temperature sensor 100 in a timely and efficient manner.

[0041] Optionally, the first straight segment 310 and the second straight segment 320 remain perpendicular. It is easy to understand that in other embodiments of the present invention, the air duct 300 may be an arc-shaped channel or a straight pipe facing the temperature sensor 100. This is just an example and is not limited to any specific embodiment.

[0042] from Figure 5 As can be seen, in the optional embodiment, the air outlet box 400 also includes a mating through hole 430; the temperature sensor 100 includes a main body and a signal line connected to each other, with the signal line passing through the mating through hole 430 and extending to the bottom of the air outlet box 400. Thus, the air outlet box 400 can also serve as the mounting path for the temperature sensor 100, making the structure of the air outlet box 400 more compact. In this embodiment, the mating through hole 430 penetrates the air outlet box 400, and the cross-section of the mating through hole 430 is rectangular.

[0043] Please see Figures 1 to 4As shown in the figure, in an optional embodiment, the gas stove further includes a probe holder 500, to which the temperature sensor 100 is connected; the probe holder 500 has a through vent 520, which faces the outer wall of the temperature sensor 100; and an air duct 300 is connected to the vent 520. Here, the probe holder 500 ensures the stability of the temperature sensor 100 and continues to guide the cooling airflow from the blower 200 toward the outer wall of the temperature sensor 100, thus ensuring the cooling of the temperature sensor 100.

[0044] Specifically, in this embodiment, there are two vents 520, each facing one of the two bellows outlets 420. The cross-section of the vent 520 is semi-circular.

[0045] from Figure 4 It can also be seen that, in an optional embodiment, the probe holder 500 has a through mounting hole 510 at its center, and a vent 520 is arranged radially outward from the mounting hole 510; the temperature sensor 100 can pass through the mounting hole 510. This ensures that the temperature sensor 100 can operate stably and efficiently, while also improving the compactness of the gas stove.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 As can be seen from the figure, in an optional embodiment, the gas stove also includes a burner 600, which has a central through hole 601. The temperature sensor 100 passes through the central through hole 601 and extends to the top of the burner 600. The airflow from the air outlet 210 of the blower 200 can be guided to the central through hole 601. A through gas supply hole 611 is provided at the top of the burner 600, which is connected to the central through hole 601.

[0047] By cooperating with the blower 200 and the air supply port 611, the cooling airflow from the outlet 210 of the blower 200 can not only rapidly cool the temperature sensor 100, but also guide part of the cooling airflow to the burner 600 to supplement secondary air.

[0048] Specifically, in this embodiment, the vent 520 of the probe holder 500 is directly aligned with the central through hole 601. That is, the air duct 300 of the air outlet box 400 and the vent 520 of the probe holder 500 correspond to the central through hole 601 of the burner 600. In this way, the cooling airflow of the blower 200 is guided to cool the temperature sensor 100, while also replenishing secondary air to the burner 600.

[0049] from Figure 6As can be seen from the optional embodiment, the burner 600 includes a copper core 610, and the gas supply hole 611 is arranged circumferentially along the copper core 610. The burner head 620 is disposed on the water receiving tray, and the copper core 610 is disposed on the top of the burner head 620; the temperature sensing probe 100 passes through the burner head 620 and the copper core 610 in sequence, and is placed above the copper core 610.

[0050] In an optional embodiment, there are multiple air supply holes 611, which are evenly distributed circumferentially on the copper core 610. This arrangement allows the gas appliance to receive more secondary air, thereby helping the gas to burn more completely and achieving the dual effect of reducing flue gas (such as carbon monoxide) emissions and improving the thermal efficiency of the stove.

[0051] As can also be seen from the figure, the gas stove in this embodiment also includes a chassis 11, an air inlet pipe 12, a valve body 13, a knob 14, a control center 15, a main branch gas pipe 16, a secondary branch gas pipe 17, a nozzle seat 18, a temperature display component, a panel 20, a water tray 21, and a pot rack 22.

[0052] The air intake pipe 12 is mounted on the chassis 11 via an air intake pipe bracket; the valve body 13 is mounted on the air intake pipe 12. A knob 14 is located on the valve body 13. A water tray 21 is located on the panel 20, a boiler rack 22 is located on the water tray 21, and the burner 600 is located at the center of the boiler rack 22.

[0053] The main branch air pipe 16 is connected to the main air pipe of the nozzle seat 18 through the main air pipe of the valve body 13, and the auxiliary branch air pipe 17 is connected to the auxiliary air pipe of the nozzle seat 18 through the auxiliary air pipe of the valve body 13.

[0054] The control center 15 is mounted on the chassis 11; the blower 200 is mounted to the chassis 11 via a blower bracket using screws. The nozzle seat 18 is fixed to the chassis 11 via nozzle feet. The blower 200 is fixed to the blower bracket via blower 200 fixing holes. The temperature sensor 100 is mounted on the sensor mounting base 500 via a sensor support 23, and the sensor mounting base 500 is mounted on the nozzle seat 18. A fixing sealing gasket is located between the bottom of the sensor mounting base 500 and the nozzle seat 18. The inlet of the air outlet box 400 is inserted into the outlet 210 of the blower 200, allowing for internal air communication.

[0055] The temperature display assembly includes a temperature display panel and a temperature display screen 19. The panel 20 is mounted on the chassis 11.

[0056] The temperature display panel is mounted on the back of the panel 20 and is tightly fitted to the temperature display screen 19, which is illuminated by the panel 20. The panel 20 is mounted on the chassis 11. The water receiving tray 21 is located above the panel 20 and is screwed onto the nozzle seat 18.

[0057] During assembly, ensure that the vent 520 of the probe mounting base 500 is connected to the air box outlet 420 of the air box 400. Specifically, the air duct 300 path is: air inlet of blower 200 → air outlet 210 of blower 200 → air box inlet 410 → air box outlet 420 → vent 520 of probe mounting base 500. After the blower 200 is started, external cold air is drawn in from the air inlet at the bottom of the blower 200, and then forced into the air box 400 through the air outlet 210 and the air box inlet 410. After passing through the air duct 300 inside the air box 400, the air flows out from the air box outlet 420. The airflow enters the central through hole 601 of the burner 600 through the vent hole 520 of the probe fixing seat 500. At this time, the airflow is divided into two paths: one main branch airflow passes through the central through hole 601 of the burner 600 and blows directly towards the root and side of the temperature sensing probe 100, forming local forced convection heat dissipation; the other branch airflow enters the air supply through hole 611 of the copper core 610 through the central through hole 601 according to the conventional path, providing some air for combustion.

[0058] Intelligent control process: The control center 15 receives signals from the temperature sensor 100 in real time. When the system determines that the current cooking mode is high-temperature (such as stir-frying), or the sensor reading rises sharply in a short period of time (indicating that the internal environment is overheated), or when heat dissipation needs to be strengthened according to the preset program, the control center 15 will send a command to the blower 200 to increase the speed of the blower 200. After the speed is increased, the cooling airflow blowing towards the temperature sensor 100 increases, quickly removing the heat around it; when the system determines that the current cooking mode is low-temperature (such as simmering soup), the temperature is stable and the heat dissipation demand is reduced, so the speed of the blower 200 also decreases, thereby achieving intelligent adjustment, energy saving and emission reduction. Through the above methods, the present invention effectively ensures the working accuracy of the temperature sensor 100 in high-temperature environments, and simultaneously optimizes the combustion effect, reduces the emission of harmful gases, and improves thermal efficiency.

[0059] In summary, the embodiments of the present invention provide a gas stove that has at least the following advantages: An air duct 300 is added to the bottom of the temperature sensor 100, and cooling is achieved through a blower 200. In this way, the speed of the blower 200 can be intelligently controlled according to different cooking environment requirements to reduce the ambient temperature around the sensor, greatly improving the detection accuracy of the intelligent stove.

[0060] By controlling the airflow of the blower (200), a certain amount of secondary air can be added to the copper core combustion chamber. This helps reduce flue gas emissions and improve thermal efficiency.

[0061] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
