Description

Technical Field

[0001] The invention belongs to the field of intelligent control of gas stoves, and in particular relates to a method and system for self-learning and self-calibration of a gas stove. Background Art

[0002] In today's society, gas stoves are one of the essential kitchen appliances and are widely used in home and commercial kitchens. Due to their convenient and fast cooking methods, gas stoves are used relatively frequently. During the cooking process, especially in major cooking methods such as stewing, a long time is required, and users need to supervise for a long time to ensure that the food can be cooked or burned to the ideal degree.

[0003] In order to meet the needs of users and improve the cooking experience, gas stoves at this stage have added some intelligent functions on the basis of basic cooking functions. For example, through the touch timing function, users can enter the timing mode and select the cooking time by repeatedly touching the plus and minus buttons. Once the set time is reached, the gas stove will automatically turn off the fire. This intelligent timing function can make users more flexible and free during the cooking process, and can do other things at the same time without paying too much attention to cooking. However, the touch timing function that is common in the market, although it provides a certain convenience, cannot detect abnormal situations, and thus cannot guarantee the cooking effect expected by users. For example, if the food in the pot overflows or the fire goes out, the gas stove cannot sense these abnormal situations, and continues to time and turn off the fire, resulting in the food not being cooked or being burnt.

[0004] Traditional gas stoves are unable to monitor indicators such as temperature, pressure, and flame conditions during the cooking process, and are unable to sense abnormal situations. For example, if food overflows from the pot or the flame goes out, the gas stove will automatically stop timing and issue corresponding warning prompts to prevent the food from continuing to cook or becoming burnt. At the same time, traditional gas stoves are unable to record these abnormal conditions and automatically avoid similar situations from happening again in subsequent use. In addition, traditional gas stoves are unable to learn based on user usage habits and cooking needs, and continuously optimize their own cooking programs and instructions, and are unable to adapt to the cooking habits of different users.

[0005] The present invention is proposed in view of the above problems in order to solve these problems. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method and system for self-learning and self-calibration of a gas stove. The invention solves the problem of the traditional gas stove's inability to perceive abnormal conditions. Through the self-learning and self-calibration function, the calibration model is continuously optimized according to the different pots used by users and the feedback information of the flame sensor, so that the gas stove can adapt to the use requirements of different types of pots, thereby improving the intelligence level of the gas stove.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a self-learning control method for a gas stove, after ignition, obtains the temperature change of the bottom of the pot, and identifies the boiling state in the pot according to the temperature change of the bottom of the pot, wherein the boiling state at least includes a slight boiling state and a balanced state; when the temperature change rate meets a first preset value, it is judged to be a slight boiling state, and when the temperature change rate meets a second preset value, it is judged to be a balanced state;

[0008] Recording the temperature information of the pot bottom when entering the slightly boiling state and the equilibrium state, wherein the temperature information of the pot bottom at least includes a first temperature value T1 when entering the slightly boiling state and a second temperature value T2 when entering the equilibrium state;

[0009] Establishing a mapping relationship between the cookware information and the first temperature value T1 and the second temperature value T2;

[0010] The fire power of the gas stove is adjusted according to the difference between the current pot bottom temperature T0 and the first temperature value T1 or the second temperature value T2.

[0011] Furthermore, according to the difference between the current pot bottom temperature T0 and the first temperature value T1 or the second temperature value T2, the method for adjusting the firepower is:

[0012] Determine whether the current pot bottom temperature T0 is less than T1, and T1-T0>ω. If so, maintain the current fire power or increase the current fire power;

[0013] Determine whether the current pot bottom temperature T0 is less than T1, and T1-T0≤ω. If so, reduce the current fire power;

[0014] Determine whether the current pot bottom temperature T0 is greater than T1 and less than T2. ​​If so, reduce the current fire power;

[0015] The value range of ω is 0<ω<5.

[0016] Furthermore, according to the difference between the current pot bottom temperature T0 and the first temperature value T1 or the second temperature value T2, the method for adjusting the firepower is:

[0017] Determine whether the current pot bottom temperature T0 is greater than T2, if so, turn off the gas stove.

[0018] Furthermore, the value range of the first preset value is that within the preset time period, the temperature change range does not exceed 3-5°C, and the value range of the preset time period is 3-8 seconds. Preferably, the value of the preset time period is 5 seconds.

[0019] Furthermore, the value range of the second preset value is that within the preset time period, the temperature change range does not exceed 0-3°C, and the value range of the preset time period is 3-8 seconds. Preferably, the value of the preset time period is 5 seconds.

[0020] Furthermore, the method also includes generating a temperature curve according to the temperature change of the pot bottom, comparing it with a preset temperature curve, and obtaining the pot information according to the comparison result.

[0021] Furthermore, the method also includes obtaining the change in flame temperature of the gas stove after ignition. If the temperature of the bottom of the pot remains unchanged or rises and the flame temperature drops rapidly within a preset time period, it is determined that overflow has occurred and the gas stove is turned off.

[0022] Further, when the decreasing rate of the flame temperature is greater than 450 degrees / second, it is determined that overflow occurs;

[0023] When the rate of decrease of the flame temperature is no more than 450 degrees per second, it is determined that flameout has occurred.

[0024] Furthermore, the method also includes, after ignition, obtaining the change in the flame temperature of the gas stove. Within a preset time period, if the temperature of the bottom of the pot remains unchanged or increases, and the flame temperature slowly decreases, it is determined that the flameout has occurred and the gas stove is ignited again.

[0025] Furthermore, a control system of a gas stove self-learning control method,

[0026] The control system includes a gas electromagnetic valve, a pot bottom temperature sensor, a flame sensor, a controller and a memory; the pot bottom temperature sensor is used to detect the pot bottom temperature, the flame sensor is used to detect the flame temperature, the memory is used to store pot information and temperature information, and the controller is used to control the action of the gas electromagnetic valve.

[0027] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0028] A method and system for self-learning and self-calibration of a gas stove. The method recognizes the pot after ignition. The controller determines the boiling state in the pot according to the change in the temperature of the pot bottom, controls the flame size, maintains the pot in a slightly boiling state, and records the firepower from the slightly boiling state to the balanced state. When the pot is used again for cooking and reaches the slightly boiling state, the controller controls the firepower of the gas stove to be less than the firepower when the pot overflows. The method can accurately determine the type of pot through self-learning, maintain the vitality of the gas stove to the balanced state, and avoid the effect of being unable to complete cooking due to overflowing. The cause of flameout can be accurately determined by the rate of change of the thermoelectromotive force of the flame sensor, whether it is overflowing, wind blowing or lack of oxygen, or the disconnection of the gas valve. In this way, the problem can be solved in a targeted manner to avoid misjudgment and unnecessary intervention. The flame sensor's thermoelectromotive force change rate can be used to judge the overflow situation, which can quickly detect the overflow situation, thus avoiding the occurrence of safety hazards such as flame loss of control, gas leakage and fire; based on the judgment result, the controller can adjust the firepower of the gas stove to make it smaller than the firepower when the pot overflows, thus reducing the probability of overflowing and ensuring the safety and stability of the cooking process. Through the rapid judgment of the flame sensor, the time for manual intervention and judgment can be reduced, and the detection and response efficiency of the gas stove can be improved, which can save time and energy and improve cooking efficiency. Through the change rate of the thermoelectromotive force of the flame sensor, the cause of the gas stove's flameout can be judged, the flame status of the gas stove can be monitored in real time, the gas stove can be quickly responded to the flameout situation, and timely measures can be taken to avoid accidents or fires.

[0029] If an unexpected flameout occurs and it is determined that the cause of the flameout is overflowing, the controller will learn the firepower when the pot overflowed. When this type of pot is used for cooking again, the controller will control the gas stove to have a firepower lower than that when the pot overflowed. By self-learning the flame size when the pot overflowed and automatically adjusting the flame size, user intervention and adjustment can be reduced, providing a more convenient user experience. Users only need to set the desired cooking effect, and the controller will automatically adjust the flame size according to temperature changes without the need to frequently adjust knobs or switches.

[0038] Example 1

[0039] A self-learning control method for a gas stove, the gas stove includes a burner, a gas electromagnetic valve, a pot bottom temperature sensor, and a controller. After ignition, the pot is identified, and the controller detects temperature changes according to the pot bottom temperature sensor. After ignition, the controller obtains the temperature change of the pot bottom, calculates the temperature trend according to the temperature change, and identifies the boiling state in the pot according to the temperature change of the pot bottom, wherein the boiling state at least includes a slight boiling state and an equilibrium state; when the temperature change rate meets a first preset value, the temperature range of the first preset value is within a preset time period, and the temperature change range does not exceed 3-5°C, and the value range of the preset time period is 3-8 seconds. Preferably, the value of the preset time period is 5 seconds, and it is judged to be a slight boiling state; for example: the temperature range of the first preset value can be that when the preset time is 5 seconds, the temperature change is 4°C; or, when the first preset value The temperature range value may be that when the preset time is 4 seconds, the temperature change is 3°C; or, when the temperature range value of the first preset value is that when the preset time is 6 seconds, the temperature change is 5°C; at this time, it is judged to be a slightly boiling state; when the temperature change rate meets the second preset value, the value range of the second preset value is that within the preset time period, the temperature change range does not exceed 0-3°C, and the value range of the preset time period is 3-8 seconds. Preferably, the value of the preset time period is 5 seconds. For example, the temperature range value of the second preset value may be that when the preset time is 5 seconds, the temperature change is 1°C; or, when the temperature range value of the second preset value is that when the preset time is 3 seconds, the temperature change is 2°C; or, when the temperature range value of the second preset value is that when the preset time is 6 seconds, the temperature change is 0°C; at this time, it is judged to be an equilibrium state;

[0040] The controller records the temperature information of the pot bottom when entering the slightly boiling state and the equilibrium state, wherein the temperature information of the pot bottom at least includes a first temperature value T1 when entering the slightly boiling state and a second temperature value T2 when entering the equilibrium state;

[0041] Establishing a mapping relationship between the cookware information and the first temperature value T1 and the second temperature value T2;

[0042] The fire power of the gas stove is adjusted according to the difference between the current pot bottom temperature T0 and the first temperature value T1 or the second temperature value T2.

[0043] In this embodiment, by using this gas stove self-learning control method and recording the temperature information of the bottom of the pot, the controller can automatically judge and adjust the firepower of the gas stove according to the characteristics of different pots and the temperature changes of the bottom of the pot, thereby achieving more accurate firepower control; by judging the boiling state in the pot, the gas stove can adjust the firepower in time to avoid liquid overflow in the pot or food burning, thereby improving the safety and quality of cooking.

[0044] In this embodiment, the change in the boiling state in the pot is judged according to the different temperature change rates, so that the gas stove can reduce the firepower at an appropriate time, save gas consumption, and achieve energy-saving and environmental protection effects; this self-learning control method is automatic, and the user does not need to manually adjust the firepower, which simplifies the operation process and improves the user experience.

[0045] In this embodiment, according to the difference between the current pot bottom temperature T0 and the first temperature value T1 or the second temperature value T2, the method for adjusting the firepower is:

[0046] Determine whether the current pot bottom temperature T0 is less than T1, and T1-T0>ω. If so, maintain the current fire power or increase the current fire power;

[0047] Determine whether the current pot bottom temperature T0 is less than T1, and T1-T0≤ω. If so, reduce the current fire power;

[0048] Determine whether the current pot bottom temperature T0 is greater than T1 and less than T2. ​​If so, reduce the current fire power;

[0049] The value range of ω is 0<ω<5.

[0050] In this embodiment, the first temperature value T1 has a value range of 100-120° C., and the second temperature value T2 has a value range of 130-160° C.;

[0051] For example: if the current temperature detected is the front bottom temperature T0 of 97°C, then it is judged that the current bottom temperature T0 is T1, and T1-T0≤ω, and at this moment the controller controls the gas stove to reduce the current firepower; if the current temperature detected is the front bottom temperature T0 of 90°C, then the current bottom temperature T0 is T1, and T1-T0>ω, then at this moment the controller controls the gas stove to maintain the current firepower or increase the current firepower; when the current temperature detected is the front bottom temperature T0 of 127°C, then the current bottom temperature T1 is T0 is T2, and at this moment the controller controls the gas stove to reduce the current firepower.

[0052] In this embodiment, adjusting the firepower according to the difference between the current pot bottom temperature and the first temperature value or the second temperature value can ensure that the pot bottom temperature is close to the preset temperature value, thereby improving the utilization efficiency of the gas. If the current temperature is significantly different from the preset temperature, the firepower is maintained or increased to quickly heat up; if the difference is small, the firepower is appropriately reduced to maintain a stable heating state; by accurately adjusting the firepower, a more stable and uniform heating effect can be provided, avoiding overheating or undercooking of food, thereby improving the cooking effect and taste.

[0053] In this embodiment, according to the difference between the current pot bottom temperature T0 and the first temperature value T1 or the second temperature value T2, the method for adjusting the firepower is:

[0054] Determine whether the front pot bottom temperature T0 is greater than T2, if so, turn off the gas stove.

[0055] In this embodiment, when the decreasing rate of the flame temperature is not greater than 450 degrees / second, it is determined that flameout has occurred.

[0056] In this embodiment, the method further includes generating a temperature curve according to the temperature change of the bottom of the pot, and comparing it with a preset temperature curve, and obtaining the pot information according to the comparison result. The pot information is obtained because different pots have different thermal conductivity, and therefore the temperatures of different pots when entering the slightly boiling zone are different. The pot is identified by using a software algorithm, and the temperature change curves of different pots are recorded and stored by the software algorithm. The pot used by the user is deduced by the temperature change of different pots when entering the slightly boiling state. When this pot is used for cooking again and reaches the slightly boiling state, the controller controls the firepower of the gas stove to be less than the firepower when the pot overflows. By controlling the firepower of the gas stove to be less than the firepower when the pot overflows, the consistency of the firepower can be ensured each time the pot is used, and the stability of cooking and the predictability of the results can be ensured.

[0057] In this embodiment, the gas stove can maintain a balance between a slightly boiling state and a balanced state, so that the ingredients are heated evenly and the cooking time and results are more controllable, which can improve the quality and taste of the cooking. By maintaining the firepower of the gas stove through the controller, accidents caused by excessive or insufficient firepower can be avoided, reducing the risk of fire and safety accidents; by automatically adjusting the firepower through the controller, the firepower can be kept within an appropriate range at all times, reducing energy waste and consumption. This not only saves energy, but also plays a positive role in environmental protection.

[0058] In this embodiment, the method also includes, after ignition, obtaining the change in the flame temperature of the gas stove. Within a preset time period, if the temperature of the bottom of the pot remains unchanged or rises, and the flame temperature drops rapidly, when the rate of decrease of the flame temperature is greater than 450 degrees / second, it is determined that overflow has occurred and the gas stove is turned off.

[0059] In this embodiment, the method further includes, after ignition, obtaining the change in the flame temperature of the gas stove. Within a preset time period, if the temperature of the pot bottom remains unchanged or rises, and the flame temperature slowly decreases, it is determined that the flameout is caused by wind and / or a gas stove failure, and the wireless communication module is used to send the temperature of the gas stove when the flameout occurs, the knob angle of the gas solenoid valve, and the firepower data to the user so that the user can remotely understand the data of the gas stove when the flameout occurs and control it in real time. The specific user can use the gas stove APP to remotely understand the data of the gas stove when the flameout occurs and control it in real time; after the user controls it, the gas stove is re-controlled to ignite again;

[0060] Through wireless communication, users can be notified of the flameout of the gas stove in real time. Users can understand the situation remotely and make corresponding control and processing in time.

[0061] Users can use wireless communication to understand the status of the gas stove at any time without being restricted by time and space. This makes it convenient for users to monitor the status of the gas stove when they are out or in other scenarios to ensure the safety and comfort of the family. Through remote real-time control, users can take quick measures, such as closing the gas valve or adjusting the fire power, to prevent accidents from happening to the gas stove, thus preventing potential risks and hazards in advance.

[0064] In this embodiment, by using multiple sensors for monitoring, including a pot bottom temperature sensor and a flame sensor, the temperature change and flame state of the gas stove can be fully monitored, providing a more accurate control basis.

[0065] In this embodiment, by monitoring the temperature of the pot bottom and the flame temperature, the controller can automatically adjust the switch of the gas electromagnetic valve according to the set algorithm and the preset temperature range to achieve precise adjustment of the firepower;

[0066] By using the memory to record the pot information and temperature information, a mapping relationship between the pot and temperature changes is established, and a reference is provided in subsequent use to achieve personalized control of different pots; the memory can record and store the bottom temperature information and pot information. Through continuous learning and accumulation, the controller can analyze and judge based on historical data and algorithms, provide more accurate firepower control, and gradually achieve automatic adaptation to different cooking situations.

[0067] In this embodiment, by real-time monitoring of the flame state, such as monitoring whether there is an open flame or an extinguished flame, the safety of the gas stove can be improved, and an alarm can be issued in time or measures can be taken to prevent the occurrence of safety accidents.
