Description

Technical Field

[0001] This invention relates to a burner and a blower control method. Background Technology

[0002] The burner uses a temperature control probe to measure the temperature at the bottom of the cookware. When the bottom temperature is too high, the temperature control probe assembly can provide timely feedback and prevent dry burning, thus avoiding dangerous situations. The temperature control probe is usually located in the middle of the burner cap. When the burner is in use, combustion occurs at the burner cap, generating a large amount of high-temperature flue gas, which can easily cause thermal interference to the temperature control probe, hindering its accurate temperature measurement.

[0003] In actual use, the degree of thermal interference to the temperature control probe varies depending on the burner's heat output. Especially when the burner is at a high heat output, the temperature measured by the probe may be higher than the actual temperature of the bottom of the pot. If the probe detects the burner as dry-burning and extinguishes it, it will negatively impact the user experience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the thermal interference caused by high-temperature flue gas to the temperature control probe in the prior art, which causes the burner to erroneously judge that the pot is in a dry-burning state and thus affect the user experience. The present invention provides a burner and blower control method.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A burner includes a temperature control probe assembly, the temperature control probe assembly including a probe for measuring the temperature of the bottom of a cookware when the burner is operating, characterized in that...

[0007] The temperature control probe assembly includes a blower, and there is an air duct between the blower and the probe. The air outlet of the blower is connected to the air duct.

[0008] The voltage of the blower is adjustable.

[0009] In this design, during burner operation, the probe is placed against the bottom of the cookware to measure its temperature. An air duct connects the blower and the probe; the airflow generated by the blower passes through this duct to the probe. This airflow acts as a barrier between the probe and the high-temperature flue gas, reducing the amount of high-temperature flue gas near the probe and thus minimizing thermal interference caused by the flue gas. The blower's voltage is adjusted to control the airflow strength. During burner operation, the blower can provide different airflow strengths depending on the situation. When the cookware bottom temperature is low or the burner's heat is low, the blower's voltage is low to reduce energy consumption; when the cookware bottom temperature is high or the burner's heat is high, the voltage is increased to enhance the airflow's ability to block the high-temperature flue gas, thereby improving the blower's adaptability and enhancing the user experience.

[0010] Preferably, the burner includes a control unit, which is electrically connected to the probe and the blower respectively. The control unit is used to receive a temperature signal from the probe and to adjust the voltage of the blower according to the temperature signal.

[0011] The temperature measured by the probe is set to at least two temperature ranges, each temperature range corresponding to a different voltage value of the blower, and the voltage value is positively correlated with the temperature.

[0012] In this solution, through the above-described setup, during use, the probe measures the temperature of the bottom of the cookware and sends a temperature signal. The control unit receives the temperature signal from the probe via electrical connection and adjusts the voltage of the blower based on the temperature signal. No other measuring elements are required, simplifying the burner's structure. The blower's airflow can adapt to different temperatures and achieves automatic control, improving its adaptability and enhancing the user experience. The temperature of the cookware bottom is divided into at least two temperature ranges, from low to high. Each temperature range corresponds to a different voltage value for the blower, meaning the blower's airflow varies depending on the temperature range. Voltage is positively correlated with temperature. When the cookware bottom temperature is low, less high-temperature smoke is produced, resulting in a lower voltage and weaker airflow from the blower, reducing interference with the flame. Conversely, when the cookware bottom temperature is high, more high-temperature smoke is produced, increasing the voltage and airflow of the blower. This effectively blocks high-temperature smoke near the probe, further improving the blower's adaptability. Furthermore, during the use of the burner, the temperature control probe assembly is used to prevent dry burning. When the temperature at the bottom of the pot is high, dry burning is more likely to occur. At this time, increasing the voltage of the blower and increasing the blower force can cool down the pot, improve the safety of the burner during use, and help improve the user experience of the burner.

[0013] Preferably, the burner further includes a fire feedback system, the control unit is electrically connected to the fire feedback system, and the fire feedback system is used to measure the firepower of the burner and transmit the firepower signal to the control unit;

[0014] The firepower feedback system measures at least two firepower ranges, each corresponding to a different voltage value of the blower.

[0015] In this solution, through the aforementioned settings, the control unit can further adjust the blower force based on the burner's flame intensity, in addition to regulating the blower's airflow based on temperature. The burner's flame intensity is divided into at least two ranges, from low to high. When the burner's flame intensity is low, less high-temperature flue gas is produced, the blower's voltage is low, and the blower's airflow is low, reducing interference between the airflow and the combustion flame. When the burner's flame intensity is high, more high-temperature flue gas is produced, the blower's voltage increases, and the blower's airflow increases, effectively blocking high-temperature flue gas near the probe. By adjusting the blower's voltage through the control unit, the blower's airflow intensity is automatically controlled, which improves the blower's reliability and adaptability, ultimately enhancing the user experience.

[0016] Preferably, the fire feedback system includes an intake pipe and a valve. The intake pipe is used to introduce gas, and the valve is disposed on the intake pipe and used to regulate the intake volume of gas. The valve has multiple opening and closing degrees, and the control unit is electrically connected to the valve. The multiple opening and closing degrees of the valve correspond to different fire ranges.

[0017] Alternatively, the fire feedback system measures the firepower of the burner based on the flow rate of the gas supplied to the burner.

[0018] In this solution, the control unit obtains the opening and closing degree of the valve through the above settings, determines the firepower of the burner based on the opening and closing degree of the valve, and adjusts the voltage of the blower according to the firepower range of the burner at this time, so as to realize the automatic control of the blower's airflow, improve the adaptability of the blower, and help improve the user experience of the burner.

[0019] Measuring the burner's firepower based on the flow rate of the incoming gas ensures the accuracy of the firepower measured by the firepower feedback system, reduces the error between the measured firepower and the actual firepower of the burner, improves the accuracy of the control unit's voltage regulation of the blower, and enables more reliable automatic control of the blower's airflow, which is beneficial to improving the user experience of the burner.

[0020] Preferably, the control unit includes a correction unit, which is electrically connected to the probe and the fire feedback system respectively, and the correction unit is used to output different correction coefficients according to different temperature ranges and fire ranges.

[0021] In this solution, a correction unit is incorporated to further adjust the voltage of the blower based on the temperature of the bottom of different cookwares and the burner's heat output during burner operation. This ensures that the blower's airflow adapts to different burner operating conditions. Adjusting the blower's airflow allows for automatic control, enhancing its adaptability and improving the user experience.

[0022] Preferably, the temperature control probe assembly includes a mounting base and a liquid storage box. The bottom of the probe is mounted on the mounting base, and the liquid storage box is disposed at the bottom of the mounting base. The liquid storage box has an internal cavity, and the side wall of the cavity has a first opening. The air outlet of the blower is connected to the first opening, and the air outlet of the blower is connected to the air duct through the cavity. The liquid storage box is used to store the overflow liquid generated by the burner during use.

[0023] In this solution, during the use of the burner, liquid inside the cookware may overflow. The overflow flows to the mounting base through the air duct. By setting up a liquid storage box, the overflow is stored in the cavity of the liquid storage box, which prevents the overflow from dripping directly onto the burner chassis and causing pollution. This makes it easier to keep the burner clean and improves the user experience of the burner.

[0024] Preferably, the liquid storage box is detachably connected to the mounting base;

[0025] And / or, the sidewall of the cavity is provided with a second opening, and the temperature control probe assembly has a wire electrically connected to the probe, the wire passing through the second opening.

[0026] In this design, the liquid reservoir and the mounting base are detachably connected, allowing users to easily clean the reservoir and remove any overflow. This facilitates routine burner maintenance and improves the user experience. A second opening is provided on the side wall of the cavity, through which the wires of the temperature control probe assembly are threaded to connect to the control unit. This ensures the cavity bottom is sealed, preventing overflow from dripping directly onto the burner chassis and causing contamination, thus keeping the burner clean.

[0027] A blower control method is used for the burner described above to regulate the voltage of the blower device, wherein the standard voltage value of the blower device is V0, and the blower control method includes the following steps:

[0028] S10, The control unit receives a temperature signal from the probe;

[0029] S20. The control unit determines the temperature range corresponding to the temperature signal and obtains the temperature coefficient A of the temperature range.

[0030] S30. The control unit acquires the voltage value V of the blower, where V = V0 * A;

[0031] S40. The control unit adjusts the voltage of the blower according to the voltage value V, so that the voltage corresponds to the voltage value V.

[0032] In this solution, the voltage of the blower is adjusted based on the measured temperature of the bottom of the cookware using the aforementioned blower control method. When the temperature of the bottom of the cookware is low, less high-temperature smoke is produced during combustion, resulting in a smaller temperature coefficient A. Consequently, the voltage of the blower is low, and the blower's airflow is weak, reducing interference between the blower airflow and the combustion flame. Conversely, when the temperature of the bottom of the cookware is high, more high-temperature smoke is produced, resulting in a larger temperature coefficient A. This leads to an increase in the voltage of the blower and the blower's airflow, effectively blocking high-temperature smoke near the probe and improving the adaptability of the blower, thus enhancing the user experience of the burner.

[0033] A blower control method is used for the burner described above to regulate the voltage of the blower device, wherein the standard voltage value of the blower device is V0, and the blower control method includes the following steps:

[0034] S10, The control unit receives a temperature signal from the probe;

[0035] S11. The control unit receives a fire signal from the fire feedback system;

[0036] S20. The control unit determines the temperature range corresponding to the temperature signal and obtains the temperature coefficient A of the temperature range.

[0037] S21. The control unit determines the fire range corresponding to the fire signal and obtains the fire coefficient B corresponding to the fire range.

[0038] S30' The control unit acquires the voltage value V of the blower, where V = V0 * A * B;

[0039] S40. The control unit adjusts the voltage of the blower according to the voltage value V, so that the voltage corresponds to the voltage value V.

[0040] In this solution, the voltage of the blower device is further adjusted according to the burner's flame intensity using the aforementioned blower control method. When the burner's flame intensity is low, less high-temperature flue gas is produced, resulting in a lower flame intensity coefficient (B), a lower voltage for the blower device, and a weaker blower force, reducing interference from the blower airflow to the combustion flame. Conversely, when the burner's flame intensity is high, more high-temperature flue gas is produced, resulting in a higher flame intensity coefficient (B), an increased voltage for the blower device, and an increased blower force. This allows the blower airflow to effectively block high-temperature flue gas approaching the probe. By adjusting the voltage of the blower device through the control unit, the blower force is automatically controlled, improving its adaptability and enhancing the user experience of the burner.

[0041] A blower control method is used for the burner described above to regulate the voltage of the blower device, wherein the standard voltage value of the blower device is V0, and the blower control method includes the following steps:

[0042] S10, The control unit receives a temperature signal from the probe;

[0043] S11. The control unit receives a fire signal from the fire feedback system;

[0044] S12, The correction unit receives a temperature signal from the probe and a fire signal from the fire feedback system;

[0045] S20. The control unit determines the temperature range corresponding to the temperature signal and obtains the temperature coefficient A of the temperature range.

[0046] S21. The control unit determines the fire range corresponding to the fire signal and obtains the fire coefficient B corresponding to the fire range.

[0047] S22, The correction unit obtains the correction coefficient k based on the temperature signal and the fire signal;

[0048] S30”, The control unit obtains the voltage value V of the blower, where V=V0*A*B*k;

[0049] S40. The control unit adjusts the voltage of the blower according to the voltage value V, so that the voltage corresponds to the voltage value V.

[0050] In this solution, the voltage of the blower is further adjusted based on the measured temperature of the bottom of the pot and the firepower of the burner, and the blower force is adjusted to achieve automatic control of the blower force, thereby improving the adaptability of the blower and enhancing the user experience of the burner.

[0051] The positive and progressive effects of this invention are as follows: During the use of the temperature control probe, the probe is placed against the bottom of the pot to measure the temperature of the bottom of the pot. An air duct exists between the blower and the probe. The airflow generated by the blower blows air onto the probe through the duct. This airflow acts as a barrier between the probe and the high-temperature flue gas, reducing the amount of high-temperature flue gas near the probe and thus reducing thermal interference caused by the high-temperature flue gas to the probe's temperature measurement. By adjusting the voltage of the blower, the blowing force of the blower can be adjusted. During the use of the burner, the blower can provide different blowing forces for different usage conditions, thereby improving the adaptability of the blower and enhancing the user experience of the burner.

[0063] Fire Feedback System 202 Detailed Implementation

[0064] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0065] Example 1

[0066] This invention provides a burner 200, such as Figure 1 and Figure 2 As shown, the burner 200 includes a temperature control probe assembly 100, which includes a probe 1. The probe 1 is used to measure the temperature of the bottom of the cookware when the burner 200 is working. The temperature control probe assembly 100 includes a blower device 2, and there is an air duct between the blower device 2 and the probe 1. The air outlet of the blower device 2 is connected to the air duct. The voltage of the blower device 2 is adjustable. During the use of the burner 200, the probe 1 is in contact with the bottom of the cookware and is used to measure the temperature of the bottom of the cookware. There is an air duct between the blower device 2 and the probe 1. The blower airflow generated by the blower device 2 blows air onto the probe 1 through the air duct. The blower airflow acts as a barrier between the probe 1 and the high-temperature flue gas, which can reduce the high-temperature flue gas close to the probe 1, thereby reducing the thermal interference caused by the high-temperature flue gas to the temperature measurement of the probe 1. By adjusting the voltage of the blower device 2, the blowing force of the blower device 2 can be adjusted. During the use of the burner 200, the blower device 2 can provide different blowing forces for different usage conditions. When the temperature of the bottom of the pot is low or the heat of the burner 200 is low, the voltage of the blower device 2 is low to reduce the energy consumption of the blower device 2. When the temperature of the bottom of the pot is high or the heat of the burner 200 is high, the voltage of the blower device 2 is increased to improve the blocking effect of the blower airflow on the high-temperature flue gas, thereby improving the adaptability of the blower device 2 and improving the user experience of the burner 200.

[0067] In this embodiment, the blower 2 is a fan, and an opening is provided on the side of the blower 2 away from the probe 1 for airflow to enter the blower 2. A fan can also be used as the blower 2. An air outlet is provided on the mounting base 3, and the air outlet of the blower 2 is connected to the air duct through the air outlet.

[0068] As a preferred implementation method, such as Figure 1 and Figure 2 As shown, the burner 200 includes a control unit 201, which is electrically connected to the probe 1 and the blower device 2. The control unit 201 receives temperature signals from the probe 1 and adjusts the voltage of the blower device 2 according to the temperature signals. The temperature measured by the probe 1 is set to at least two temperature ranges, each corresponding to a different voltage value of the blower device 2, and the voltage value is positively correlated with the temperature. During use, the probe 1 measures the temperature of the bottom of the cookware and sends a temperature signal. The control unit 201 receives the temperature signal from the probe 1 through its electrical connection and determines and adjusts the voltage of the blower device 2 according to the temperature signal. No other measuring elements are required, simplifying the structure of the burner 200. The blower device 2 can adapt to different temperatures and automatically controls the blower device 2's airflow, improving its adaptability and enhancing the user experience of the burner 200. In this embodiment, the temperature at the bottom of the cookware is divided into four temperature ranges from low to high. Each temperature range corresponds to a different voltage value of the blower device 2, meaning the blowing force of the blower device 2 varies depending on the temperature range. The voltage value is positively correlated with the temperature. When the temperature at the bottom of the cookware is low, less high-temperature smoke is produced during combustion, the voltage of the blower device 2 is low, and the blowing force of the blower device 2 is weak, reducing the interference of the blowing airflow on the combustion flame. When the temperature at the bottom of the cookware is high, more high-temperature smoke is produced during combustion, the voltage of the blower device 2 increases, and the blowing force increases. The blowing airflow can effectively block the high-temperature smoke approaching the probe 1, improving the adaptability of the blower device 2. Furthermore, during the use of the burner, the temperature control probe assembly 100 is used to prevent dry burning. When the temperature at the bottom of the cookware is high, dry burning is more likely to occur. In this case, increasing the voltage of the blower device 2 and increasing the blowing force can cool the cookware, improving the safety of the burner 200 during use and enhancing the user experience of the burner 200.

[0069] As a preferred implementation method, such as Figure 1 and Figure 2As shown, the burner 200 also includes a fire feedback system 202. The control unit 201 is electrically connected to the fire feedback system 202. The fire feedback system 202 is used to measure the firepower of the burner 200 and transmit the firepower signal to the control unit 201. The firepower measured by the fire feedback system 202 is set with at least two firepower ranges, each firepower range corresponding to a different voltage value of the blower 2. The control unit 201 can further adjust the blower force according to the firepower of the burner 200, based on the blower force of the blower 2, in addition to adjusting the blower force of the blower 2 by temperature. In this embodiment, the burner 200 has four power levels, ranging from low to high. When the burner 200 has a low power level, less high-temperature flue gas is produced, the voltage of the blower 2 is low, and the blower 2 has a low airflow, reducing interference between the blower airflow and the combustion flame. When the burner 200 has a high power level, more high-temperature flue gas is produced, the voltage of the blower 2 increases, and the blower airflow increases, effectively blocking the high-temperature flue gas near the probe 1. By adjusting the voltage of the blower 2 through the control unit 201, the airflow of the blower 2 is automatically controlled, which improves the reliability and adaptability of the blower 2 and enhances the user experience of the burner 200.

[0070] In a preferred embodiment, the fire feedback system 202 includes an intake pipe and a valve. The intake pipe is used to introduce gas, and the valve is installed on the intake pipe to regulate the gas intake volume. The valve has multiple opening and closing degrees. The control unit 201 is electrically connected to the valve, and the multiple opening and closing degrees of the valve correspond to different fire intensity ranges. An angle sensor is installed on the valve to obtain the rotation angle of the valve. The angle sensor is electrically connected to the control unit 201. The control unit 201 calculates the opening and closing degree of the valve based on the rotation angle of the valve measured by the angle sensor, determines the fire intensity of the burner 200 based on the opening and closing degree of the valve, and adjusts the voltage of the blower 2 according to the corresponding fire intensity range of the burner 200 at this time. This achieves automatic control of the blower 2's airflow, improves the adaptability of the blower 2, and helps to improve the user experience of the burner 200.

[0071] As a preferred implementation, the fire feedback system 202 measures the firepower of the burner 200 based on the flow rate of the gas supplied to the burner, that is, it measures the amount of gas passing through the intake pipe per unit time. This ensures the accuracy of the firepower measured by the fire feedback system 202, reduces the error between the measured firepower and the actual firepower of the burner 200, improves the accuracy of the voltage regulation of the blower device 2 by the control unit 201, and achieves more reliable automatic control of the blower device 2's airflow, which is beneficial to improving the user experience of the burner 200.

[0072] In a preferred embodiment, the control unit 201 includes a correction unit electrically connected to the probe 1 and the fire feedback system 202. The correction unit outputs different correction coefficients based on different temperature and fire intensity ranges. By setting the correction unit, the voltage of the blower device 2 is further corrected according to the different temperatures of the bottom of the cookware and the fire intensity of the burner 200 during use, so that the blower force of the blower device 2 can adapt to different operating states of the burner 200. When the temperature and fire intensity of the cookware bottom are both low, less high-temperature smoke is produced, the voltage of the blower device 2 is low, and the blower force of the blower device 2 is low, reducing the interference of the blower airflow on the combustion flame. Alternatively, when the burner 200 first starts working, there may be a situation where the fire intensity is high but the temperature is low; or if the medium inside the cookware, such as water, is abundant, the temperature of the bottom of the cookware is still relatively low. In this case, the blower force of the blower device 2 is low, reducing the impact of the blower airflow on the fire intensity of the burner 200. When the temperature and heat of the cookware bottom are at a medium level, the burner 200 is usually in normal working condition. Therefore, the correction unit makes a small correction to the voltage of the blower 2, and the voltage of the blower 2 is close to the voltage during normal operation. When the temperature of the cookware bottom is high or the heat is strong, the correction unit further corrects and increases the voltage of the blower 2. The higher voltage of the blower 2 results in a stronger airflow, which helps to block the high-temperature flue gas near the probe 1 and cools the bottom of the cookware. This improves the safety of the burner 200, reduces thermal interference when the probe 1 measures temperature, facilitates automatic control of the blower 2's airflow, enhances the adaptability of the blower 2, and improves the user experience of the burner 200.

[0073] In specific implementation, such as Figure 1 As shown, the temperature control probe assembly 100 includes a mounting base 3 and a liquid storage box 4. The probe 1 is mounted on the mounting base 3, and the liquid storage box 4 is located at the bottom of the mounting base 3. The liquid storage box 4 has an internal cavity, and the side wall of the cavity has a first opening. The air outlet of the blower 2 is connected to the first opening, and the air outlet of the blower 2 is connected to the air duct through the cavity. During the use of the burner 200, liquid inside the cookware may overflow. The liquid storage box 4 is used to store the overflow generated by the burner 200 during use. The overflow flows to the mounting base 3 through the air duct. By setting up the liquid storage box 4, the overflow is stored in the cavity of the liquid storage box 4, which prevents the overflow from dripping directly onto the base of the burner 200 and causing pollution. This facilitates the cleanliness of the burner 200 and improves the user experience of the burner 200.

[0074] As a preferred implementation method, such as Figure 1As shown, the liquid storage box 4 and the mounting base 3 are detachably connected, which makes it easy for users to clean the liquid storage box 4 and remove the overflow stored therein, which facilitates the daily maintenance of the burner 200 and helps to improve the user experience of the burner 200.

[0075] In this embodiment, the bottom of the mounting base 3 extends downward, and the top of the liquid storage box 4 is connected to the bottom of the mounting base 3. The liquid storage box 4 and the bottom of the mounting base 3 together form a cavity. The mounting base 3 and the liquid storage box 4 are snap-fitted together, which facilitates the installation and removal of the liquid storage box 4 relative to the mounting base 3. In other alternative embodiments, the liquid storage box 4 can also be connected to the mounting base 3 by means of threaded connection, magnetic adsorption, adhesive connection, etc.

[0076] In specific implementation, such as Figure 1 As shown, the side wall of the cavity is provided with a second opening. The temperature control probe assembly 100 has a wire that is electrically connected to the probe 1. The wire passes through the second opening to ensure the sealing of the bottom of the cavity, prevent overflow from dripping directly onto the chassis of the burner 200 and causing pollution, and facilitate the cleaning of the burner 200.

[0077] Example 2

[0078] The present invention also provides a blower control method, such as Figure 3 As shown, the blower control method is used in the burner 200 of the above embodiment 1 to adjust the voltage of the blower device. The standard voltage value of the blower device 2 is V0. The blower control method includes the following steps:

[0079] S10, Control unit 201 receives temperature signal from probe 1;

[0080] S20, Control unit 201 determines the temperature range corresponding to the temperature signal and obtains the temperature coefficient A of the temperature range;

[0081] S30, Control unit 201 obtains the voltage value V of blower 2, where V = V0 * A;

[0082] S40, Control unit 201 adjusts the voltage of blower 2 according to voltage value V, so that the voltage corresponds to voltage value V.

[0083] The voltage of the blower device 2 is adjusted according to the measured temperature of the bottom of the cookware using the above-described blower control method. In this embodiment, the value of A is shown in Table 1. When the temperature of the bottom of the cookware is low, less high-temperature smoke is produced by combustion, and the temperature coefficient A is small. At this time, the voltage of the blower device 2 is low, and the blowing force of the blower device 2 is small, reducing the interference of the blower airflow on the combustion flame. When the temperature of the bottom of the cookware is high, more high-temperature smoke is produced by combustion, so the temperature coefficient A is large. The voltage of the blower device 2 increases, the blowing force increases, and the blower airflow can effectively block the high-temperature smoke close to the probe 1, improving the adaptability of the blower device 2 and improving the user experience of the burner 200.

[0084] In practice, the control system repeats the above-mentioned blower control method once every adjustment cycle. In this embodiment, an adjustment cycle is 2 seconds.

[0085] Table 1

[0086]

[0087] In Table 1, when the temperature of the bottom of the pot is below 70℃, the burner 200 is in the initial stage of combustion or there is a large amount of liquid medium inside the pot. Therefore, the temperature coefficient A is relatively small, and the blowing force of the blower 2 is relatively small, reducing the interference of the blowing airflow on the combustion flame. At the same time, the burner 200 can quickly heat the pot, increasing combustion efficiency. When the temperature of the bottom of the pot is between 70-220℃, the burner 200 is usually in normal cooking mode, and the blowing force of the blower 2 is moderate, ensuring that it can effectively block the high-temperature flue gas while avoiding interference of the blowing airflow on the combustion flame. When the temperature of the bottom of the pot is above 220℃, the pot is likely to be in a dry-burning state. Therefore, the blowing force of the blower 2 is increased to reduce the thermal interference of the high-temperature flue gas on the probe 1, reduce the deviation between the temperature measured by the probe 1 and the actual temperature support of the bottom of the pot, and at the same time, the blowing airflow can further cool the bottom of the pot, ensuring the safe use of the burner 200.

[0088] Example 3

[0089] This embodiment provides a blower control method. The blower control method is used in the burner of Embodiment 1 above to adjust the voltage of the blower device. The standard voltage value of the blower device is V0. The blower control method includes the following steps:

[0090] S10, Control unit 201 receives temperature signal from probe 1;

[0091] S11, Control unit 201 receives fire signals from the fire feedback system;

[0092] S20, Control unit 201 determines the temperature range corresponding to the temperature signal and obtains the temperature coefficient A of the temperature range;

[0093] S21, Control unit 201 determines the fire range corresponding to the fire signal and obtains the fire coefficient B corresponding to the fire range;

[0094] S30', Control unit 201 obtains the voltage value V of the blower, where V=V0*A*B;

[0095] S40, Control unit 201 adjusts the voltage of blower 2 according to voltage value V, so that the voltage corresponds to voltage value V.

[0096] The voltage of the blower device 2 is further adjusted according to the firepower of the burner 200 using the aforementioned blower control method. In this embodiment, the value of B is shown in Table 2. When the firepower of the burner 200 is low, less high-temperature flue gas is produced, resulting in a lower firepower coefficient B, a lower voltage of the blower device 2, and a lower blower force, thus reducing interference between the blower airflow and the combustion flame. When the firepower of the burner 200 is high, more high-temperature flue gas is produced, resulting in a higher firepower coefficient B, an increased voltage of the blower device 2, and an increased blower force, effectively blocking the high-temperature flue gas approaching the probe 1. By adjusting the voltage of the blower device 2 through the control unit 201, the automatic control of the blower force is achieved, improving the adaptability of the blower device 2 and enhancing the user experience of the burner 200.

[0097] Table 2

[0098]

[0099] In Table 2, when the power of burner 200 is below 1500W, the heat output of burner 200 is relatively low. For example, combustion only occurs at the inner ring of the burner cap, therefore the heat output coefficient B is small, and the airflow from blower 2 is weak, reducing interference between the airflow and the combustion flame. When the power of burner 200 is between 1500-4000W, burner 200 is usually in normal cooking mode, and the airflow from blower 2 is moderate, ensuring that it effectively blocks high-temperature flue gas while also preventing interference between the airflow and the combustion flame. In this embodiment, the maximum power of the burner can reach 5200W. Therefore, when the power of burner 200 is above 4000W, the airflow from blower 2 increases, reducing thermal interference from high-temperature flue gas on probe 1, reducing the deviation between the temperature measured by probe 1 and the actual temperature support at the bottom of the pot, and the airflow can further cool the bottom of the pot, ensuring the safe use of burner 200.

[0100] Example 4

[0101] This invention provides a blower control method, such as... Figure 4 As shown, the blower control method is used in the burner of Embodiment 1 above to adjust the voltage of the blower device. The standard voltage value of the blower device is V0. The blower control method includes the following steps:

[0102] S10, Control unit 201 receives temperature signals from the probe;

[0103] S11, Control unit 201 receives fire signals from the fire feedback system;

[0104] S12, The correction unit receives the temperature signal from probe 1 and the fire signal from the fire feedback system;

[0105] S20, Control unit 201 determines the temperature range corresponding to the temperature signal and obtains the temperature coefficient A of the temperature range;

[0106] S21, Control unit 201 determines the fire range corresponding to the fire signal and obtains the fire coefficient B corresponding to the fire range;

[0107] S22. The correction unit obtains the correction coefficient k based on the temperature signal and the fire signal;

[0108] S30”, control unit 201 obtains the voltage value V of the blower, where V=V0*A*B*k;

[0109] S40, Control unit 201 adjusts the voltage of the blower according to the voltage value V, so that the voltage corresponds to the voltage value V.

[0110] Using the aforementioned blower control method, the voltage of the blower device 2 is further corrected based on the measured temperature of the bottom of the cookware and the heat output of the burner 200, thereby adjusting the blower force of the blower device 2. When both the temperature and heat output of the cookware bottom are low, less high-temperature smoke is produced during combustion, resulting in a lower voltage and weaker blower force for the blower device 2, thus reducing interference from the blower airflow to the combustion flame. When both the temperature and heat output of the cookware bottom are at a medium level, the burner 200 is typically in normal operating condition. Therefore, the correction unit makes a smaller adjustment to the voltage of the blower device 2, and the voltage of the blower device 2 approximates its normal operating voltage. When the temperature at the bottom of the pot is high or the heat is strong, the correction unit further corrects and increases the voltage of the blower 2. The higher voltage of the blower 2 results in a stronger blower force, which helps to block the high-temperature flue gas close to the probe 1, reduces thermal interference when the probe 1 measures the temperature, facilitates automatic control of the blower force, improves the adaptability of the blower 2, and enhances the user experience of the burner 200.

[0111] In this embodiment, the rated voltage V0 of the blower 2 is 10V, and the value of the correction coefficient k is shown in Table 3.

[0112] Table 3

[0113]

[0114]

[0115] In this embodiment, during operation, after the burner 200 starts working and heats the cookware, the probe 1 is placed against the bottom of the cookware to measure the temperature, and the heat feedback system 202 measures the heat output of the burner 200. The probe 1 and the heat feedback system 202 are electrically connected to the control unit 201. The control unit 201 and its correction unit acquire the temperature signal from the probe 1 and the heat signal from the heat feedback system 202, and obtain the temperature coefficient, heat output coefficient, and correction coefficient, respectively, to determine and adjust the voltage of the current blower device 2. This blower control method is repeated once every adjustment cycle.

[0116] The voltage calculation formula for the blower device 2 in the above embodiments can be uniformly expressed as V=V0*A*B*k. When the voltage of the blower device 2 changes only with the temperature of the bottom of the pot or the firepower of the burner 200, the other coefficients can be taken as a fixed value.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
