Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of gas stoves, and particularly relates to a gas stove temperature control method and device, a gas stove and a storage medium. BACKGROUND

[0002] At present, a gas stove has become an essential kitchen appliance at home. A traditional gas stove usually needs to be manually adjusted in terms of fire size so as to control cooking temperature. At present, a gas stove with a temperature control function exists in the market to help users free their hands.

[0003] The gas stove with the temperature control function mainly adopts the following control logic to reach a target temperature.

[0004] 1) A user inputs a target temperature T0 in units of ℃.

[0005] 2) A temperature sensor collects a pot bottom temperature T in units of ℃ in real time.

[0006] 3) When T belongs to (-∞, T0-T1) (for example, T1 is preset as 30 ℃), the fire is automatically switched to the highest gear.

[0007] 4) When T belongs to (T0-T1, T0-T2) (for example, T2 is preset as 10 ℃), the fire is automatically switched to the middle gear.

[0008] 5) When T belongs to (T0-T2, T0), the fire is automatically further reduced, but can maintain the temperature to rise.

[0009] 6) When T belongs to (T0, +∞), the fire is automatically further reduced, but can maintain the temperature to rise.

[0010] The temperature control method can accurately reach the target temperature. Compared with a traditional stove that can only manually adjust the fire, the stove with the temperature control function is easier for users to control the fire and cook delicious food. However, the temperature control strategy has a disadvantage. Because the fire is gradually reduced as the temperature rises, compared with the constant fire temperature control mode of an ordinary stove, the time t required to reach the target temperature will become longer, and the time will also change greatly with the heat capacity of the heating medium, the amount of the heating medium and the change of the surrounding environment. Figure 1 is a heating temperature and time change curve diagram of soybean oil under different weights when two temperature control modes are adopted, for reference Figure 1 Taking the time required for the amount of the heating medium soybean oil to increase from 0.5 kg to 1 kg as an example, there is a significant difference in the temperature-time change from room temperature to the target temperature T0 under different temperature control modes. As can be seen from the curve, compared with the constant fire temperature control mode of an ordinary stove, the time required for the current temperature control stove to increase with the amount of oil increases greatly.

[0043] Embodiment one

[0044] Figure 2 A flowchart of a gas stove temperature control method provided by the embodiment one of the present application is shown in the figure. The method can be applied to the temperature control during the heating process of the gas stove. The method can be executed by a gas stove temperature control device. The device can be realized by software and / or hardware, and is generally integrated on the gas stove. In addition, it should be noted that the gas stove temperature control method of the embodiment of the present application is mainly applied to the gas stove integrated with a temperature sensor and a weight sensor.

[0045] As shown in the figure, the gas stove temperature control method provided by the embodiment one of the present application includes the following steps: Figure 2

[0046] S110, detecting the total weight of the pot and the food inside the pot on the gas stove by using the weight sensor to obtain the total load.

[0047] Firstly, the weight sensor used in this step is integrated on the gas stove, and can be specifically arranged at the burner head to weigh the pot placed on the burner head. At this time, the object weighed by the weight sensor is actually the pot and the food inside the pot. The purpose of this step of determining the total load of the burner head by using the weight sensor is to determine and confirm the temperature node of the subsequent fire adjustment based on the total load. In other words, the temperature node of the fire adjustment in the embodiment is associated with the total load.

[0048] S120, determining the preset fire adjustment node temperature according to the total load of the gas stove, and taking the fire adjustment node temperature and the target temperature under the current cooking program of the gas stove as interval division points to obtain at least three temperature intervals; wherein the fire adjustment node temperature under different total loads is different, and the fire adjustment node temperature is less than the target temperature.

[0049] ​The firepower adjustment node temperature refers to that when the pot is heated by the gas stove to the temperature, the firepower of the gas stove can be adjusted, at this time the firepower can be adjusted to adapt to the temperature feedback control, so as to avoid the temperature rising too fast or even exceeding the target temperature due to the firepower being too large, thereby ensuring the cooking effect. Therefore, this step is essentially a process of determining the node temperature for subsequent firepower adjustment based on the total load weight of the gas stove. The firepower adjustment node temperature and the total load weight have a preset corresponding relationship. The firepower adjustment node temperature can be a relatively optimal firepower adjustment node temperature determined under different total load weights through experiments, simulations or other methods based on the purpose of reducing the heating time. In this way, when the total load weight is different, different firepower adjustment node temperatures are used for firepower adjustment, and the purpose of reducing the heating time can be achieved.

[0050] In addition, the current cooking program of the gas stove can be understood as the cooking condition required by the gas stove in the current cooking process, which can be a cooking program automatically extracted by the gas stove based on the user's dish selection or cooking method selection, etc. The target temperature of the gas stove heating the pot is included. Based on the target temperature and the firepower adjustment node temperature determined according to the total load weight, at least three temperature intervals can be divided in the temperature dimension. It can be understood that when there is only one firepower adjustment node temperature, the temperature axis can be divided into a finite interval, an infinite left interval and an infinite right interval by the target temperature and the firepower adjustment node temperature. The temperature intervals divided here are mainly used as the temperature comparison basis for firepower adjustment. The number of finite intervals depends on the number of firepower adjustment node temperatures. The more node temperatures are set, the more temperature intervals are, and the control of the firepower is more precise, which helps to more accurately control the cooking process and also helps to set the specific value of the node temperature through the total load weight to reduce and improve the heating time of each temperature interval, thereby saving time in the entire cooking process.

[0051] It should be noted that since the heating process of the gas stove ends at the target temperature, the firepower adjustment node temperature determined by the total load weight in this step is essentially the temperature between the gradual heating of the gas stove to the target temperature. Therefore, it can be seen that the firepower adjustment node temperature is necessarily less than the target temperature.

[0052] S130, real-time detecting the real-time temperature of the pot by using the temperature sensor.

[0053] This step is a process of monitoring the temperature of the pot in real time by using the temperature sensor integrated on the gas stove. The temperature sensor can also be arranged at the burner position to ensure the accuracy of temperature detection.

[0054] S140, adjust the fire power of the gas stove in real time according to the temperature interval in which the real-time temperature of the pot is located; wherein, the closer the temperature interval in which the real-time temperature of the pot is located to the target temperature, the lower the fire power of the gas stove.

[0055] This step is to set the fire power adjustment node temperature according to the total weight of the load carried by the gas stove, so as to better adapt to the amount of food in the pot for fire power adjustment. As can be simply understood, when the total weight of the load carried is heavy, the heating time under the same fire power will be longer, and therefore the higher the fire power adjustment node temperature is set, the more time can be saved. On the contrary, by determining the preset fire power adjustment node temperature according to the total weight of the load carried, and by comparing the real-time temperature with the fire power adjustment node temperature for fire power control, the current total weight of the load carried can be better adapted to, the cooking effect of the food can be ensured, and the heating time can be reduced and optimized to a certain extent.

[0056] The gas stove temperature control method provided by the embodiment one of the present application first detects the total weight of the pot and the food inside the pot on the gas stove by using the weight sensor to obtain the total weight of the load carried. Secondly, the corresponding preset fire power adjustment node temperature is determined according to the total weight of the load carried by the gas stove, and the fire power adjustment node temperature and the target temperature under the current cooking program of the gas stove are taken as interval division points to obtain at least three temperature intervals. Wherein, the fire power adjustment node temperature under different total weight of the load carried is different, and the fire power adjustment node temperature is less than the target temperature. Then, the real-time temperature of the pot is detected in real time by using the temperature sensor. Finally, the fire power of the gas stove is adjusted in real time according to the temperature interval in which the real-time temperature of the pot is located. Wherein, the closer the temperature interval in which the real-time temperature of the pot is located to the target temperature, the lower the fire power of the gas stove. By using the above method, the temperature interval can be set according to the total weight of the food, and the corresponding fire power can be set according to the temperature interval in which the real-time temperature is located, so that the fire power can be accurately controlled, the fire power can be avoided to be too large or too small, the cooking effect can be ensured, the heating can be more efficiently performed, and the cooking time can be reduced and saved.

[0057] On the basis of the above-mentioned embodiment, a variant embodiment of the above-mentioned embodiment is proposed. It should be noted that, in order to make the description brief, only the differences from the above-mentioned embodiment are described in the variant embodiment.

[0058] In an embodiment, in the above-mentioned step S120, the corresponding preset fire power adjustment node temperature is determined according to the total weight of the load carried by the gas stove, specifically comprising:

[0059] The fire power adjustment node temperature is calculated according to the fitting function of the preset fire power adjustment node temperature and the total weight of the load carried and the total weight of the load carried by the gas stove. Wherein, the fitting function of the fire power adjustment node temperature and the total weight of the load carried is fitted from the relationship curve between the fire power adjustment node temperature and the total weight of the load carried under different total weight of the load carried obtained by experiment.

[0060] Wherein, the fitting function of the firepower adjustment node temperature and the total load weight can be represented as T(G) = ∑Ai*G i In the process of presetting the fitting function, experiments or simulation need to be performed in advance, that is, based on the purpose of reducing the heating time, the optimal firepower adjustment node temperature under different total load weights is obtained in advance, so as to draw the relationship curve between the firepower adjustment node temperature and the total load weight, and according to the drawn curve, the corresponding fitting function is set according to the required fitting accuracy to determine the coefficients in the fitting function. It can be understood that the more the number of terms of the fitting function is, the more accurately the fitting function can express the relationship between the firepower adjustment node temperature and the total load weight, and thus the firepower adjustment can be more accurately and optimally performed to achieve the purpose of reducing the heating time.

[0061] Embodiment Two

[0062] Figure 3 A flowchart of a gas stove temperature control method provided by Embodiment Two of the present application is provided, and Embodiment Two is optimized on the basis of the above-mentioned embodiments. In this embodiment, the firepower adjustment node temperature is calculated according to the preset fitting function of the firepower adjustment node temperature and the total load weight and the total load weight of the gas stove, which is further specified as follows:

[0063] The firepower adjustment node temperature T(G) is calculated according to the preset first-order linear fitting function T(G) = A*G + B of the firepower adjustment node temperature and the total load weight and the total load weight G of the gas stove; wherein A and B are respectively a first-order coefficient and a zero-order coefficient obtained by performing first-order linear fitting on the relationship curve between the firepower adjustment node temperature and the total load weight under different total load weights obtained through experiments.

[0064] The details of this embodiment are not described herein and can be referred to Embodiment One.

[0065] As shown in Figure 3 A gas stove temperature control method provided by Embodiment Two of the present application includes the following steps:

[0066] S210, detecting the total weight of the pot and the food inside the pot on the gas stove by using the weight sensor to obtain the total load weight.

[0067] S220, according to the preset fire power adjustment node temperature and the total weight of the bearing G, the total weight of the bearing G of the gas stove is calculated, the fire power adjustment node temperature T(G) is calculated, and the fire power adjustment node temperature and the target temperature of the gas stove under the current cooking program are taken as interval division points to obtain at least three temperature intervals; wherein A and B are the first order coefficient and zero order coefficient of the first order linear fitting of the relationship curve between the fire power adjustment node temperature and the total weight of the bearing obtained by experiment under different total weight of the bearing, and the fire power adjustment node temperature is less than the target temperature.

[0068] In this embodiment, the fitting function of the fire power adjustment node temperature and the total weight of the bearing is selected as a first order linear fitting function, which can simplify the relationship between the fire power adjustment node temperature and the total weight of the bearing, and the first order coefficient and the zero order coefficient can be obtained in the fitting process.

[0069] S230, the real-time temperature of the pot is detected in real time by using the temperature sensor.

[0070] S240, according to the temperature interval where the real-time temperature of the pot is located, the fire power position of the gas stove is adjusted in real time; wherein the closer the temperature interval where the real-time temperature of the pot is located to the target temperature, the lower the fire power position of the gas stove.

[0071] The embodiment two of the present application provides a kind of, and the preset fire power adjustment node temperature and the fitting function of the total weight of the bearing of gas stove are concretized according to the total weight of the bearing.Using this method, the corresponding relationship between the fire power adjustment node temperature and the total weight of the bearing can be more simply obtained in advance, so as to carry out temperature interval division and adjust fire power according to the temperature interval where real-time temperature is located, which can also accurately control fire power, avoid excessive or too small fire power, ensure cooking effect, more efficiently carry out heating, help to reduce and save cooking time.

[0072] Embodiment three

[0073] Figure 4 The flowchart of the temperature control method of the gas stove provided by the embodiment three of the present application is based on the optimization of the above-mentioned embodiments.In this embodiment, the corresponding preset fire power adjustment node temperature is determined according to the total weight of the bearing of the gas stove, and at least three temperature intervals are obtained by taking the fire power adjustment node temperature and the target temperature of the gas stove under the current cooking program as interval division points, which are further concretized as:

[0074] According to the first fitting function T1(G) and the second fitting function T2(G) of the preset firepower adjustment node temperature and the total load and the total load G of the gas stove, the first firepower adjustment node temperature T1 and the second firepower adjustment node temperature T2 are calculated; wherein the first fitting function T1(G) and the second fitting function T2(G) are respectively fitted by the relationship curve of the first firepower adjustment node temperature T1' and the second firepower adjustment node temperature T2' obtained by experiment under different total loads and the total load G.

[0075] The first firepower adjustment node temperature T1, the second firepower adjustment node temperature T2 and the target temperature T0 of the gas stove under the current cooking program are taken as interval division points to obtain four temperature intervals; wherein the first firepower adjustment node temperature T1, the second firepower adjustment node temperature T2 and the target temperature T0 increase in turn; the four temperature intervals include the first temperature interval (-∞, T1), the second temperature interval (T1, T2), the third temperature interval (T2, T0) and the fourth temperature interval (T0, +∞).

[0076] Therefore, according to the temperature interval in which the real-time temperature of the pot is located, the firepower level of the gas stove is adjusted in real time, which can be refined as follows:

[0077] When the real-time temperature of the pot gradually rises from the first temperature interval (-∞, T1) to the fourth temperature interval (T0, +∞), the firepower level of the gas stove is gradually reduced.

[0078] The details of the embodiment have been described in Embodiments 1 and 2.

[0079] As shown in Figure 4 The gas stove temperature control method provided by the embodiment three of the present application comprises the following steps:

[0080] S310, the total weight of the pot and the food inside the pot on the gas stove is detected by using the weight sensor to obtain the total load.

[0081] S320, according to the first fitting function T1(G) and the second fitting function T2(G) of the preset firepower adjustment node temperature and the total load and the total load G of the gas stove, the first firepower adjustment node temperature T1 and the second firepower adjustment node temperature T2 are calculated; wherein the first fitting function T1(G) and the second fitting function T2(G) are respectively fitted by the relationship curve of the first firepower adjustment node temperature T1' and the second firepower adjustment node temperature T2' obtained by experiment under different total loads and the total load G.

[0082] The step is to set two firepower adjustment node temperatures as the temperature basis for firepower adjustment, both of which are related to the total load weight, as described above, and are pre-fitted, and before fitting, data of the two firepower adjustment node temperatures under different total load weights are obtained by implementation, and the data is used for curve fitting. Specifically, both of the two fitting functions can be a linear fitting function, for example, the first fitting function T1(G) = A1 + B1*G, and the second fitting function T2(G) = A2 + B2*G.

[0083] The experimental and fitting processes of the two fitting functions are described below with specific examples:

[0084] 1) Assuming that the weight of the pot G0 = 2 kg, the pot can hold a maximum of Gmax = 2 kg of oil; the change interval of the pot weight is 2 kg ~ 4 kg, which is divided into several segments such as 5 segments, and the segment points are 2 kg, 2.5 kg, 3 kg, 3.5 kg, and 4 kg.

[0085] 2) The optimal downshift temperature points under G = 2 kg are obtained by laboratory experiments, for example, T1(G) = 30℃ and T2(G) = 10℃;

[0086] 3) Similarly, T1(G) and T2(G) under G = 2.5 kg, G = 3 kg, G = 3.5 kg, and G = 4 kg can also be obtained by experiments;

[0087] 4) The coefficients A1 and B1 in T1(G) = A1 + B1*G and the coefficients A2 and B2 in T2(G) = A2 + B2*G are obtained by linear fitting.

[0088] S330, taking the first firepower adjustment node temperature T1, the second firepower adjustment node temperature T2, and the target temperature T0 of the current cooking program of the gas stove as interval division points, four temperature intervals are obtained; wherein the first firepower adjustment node temperature T1, the second firepower adjustment node temperature T2, and the target temperature T0 increase in turn; the four temperature intervals include the first temperature interval (-∞, T1), the second temperature interval (T1, T2), the third temperature interval (T2, T0), and the fourth temperature interval (T0, +∞).

[0089] Wherein, based on the setting and determination of the two firepower adjustment node temperatures, four temperature intervals can be obtained, i.e. the first temperature interval (-∞, T1), the second temperature interval (T1, T2), the third temperature interval (T2, T0), and the fourth temperature interval (T0, +∞), which constitute the temperature basis for subsequent firepower adjustment.

[0090] S340, the real-time temperature of the pot is detected in real time by the temperature sensor.

[0091] S350, gradually reduce the fire power of the gas stove when the real-time temperature of the pot gradually rises from the first temperature interval (-∞, T1) to the fourth temperature interval (T0, +∞).

[0092] The embodiment three of the present application provides a method for determining the preset fire power adjustment node temperature according to the total weight of the gas stove, and using the fire power adjustment node temperature and the target temperature under the current cooking program of the gas stove as interval division points to obtain at least three temperature intervals. By using this method, four temperature intervals can be set by using two fire power adjustment node temperatures in actual application, and the fire power can be controlled more finely, which helps to more accurately control the cooking process, and also helps to set the specific value of the node temperature by the total weight to reduce and improve the heating time of each temperature interval, thereby saving time in the entire cooking process.

[0093] The embodiment of the present application provides several specific implementation manners on the basis of the technical solutions of the above-mentioned embodiments.

[0094] As a specific implementation manner of the present embodiment, the above-mentioned step S340 can specifically include:

[0095] when the real-time temperature of the pot is in the first temperature interval (-∞, T1), the fire power of the gas stove is adjusted to the maximum gear;

[0096] when the real-time temperature of the pot is in the fourth temperature interval (T0, +∞), the fire power of the gas stove is adjusted to the minimum gear.

[0097] As a specific implementation manner of the present embodiment, the above-mentioned step S340 can be specifically set as:

[0098] when the real-time temperature of the pot gradually rises from the first temperature interval (-∞, T1) to the fourth temperature interval (T0, +∞), the fire power of the gas stove is gradually reduced at a fixed fire power gear difference.

[0099] As another specific implementation manner of the present embodiment, the above-mentioned step S340 can be specifically set as:

[0100] when the real-time temperature of the pot gradually rises from the first temperature interval (-∞, T1) to the fourth temperature interval (T0, +∞), the fire power of the gas stove is gradually reduced at a gradually decreasing fire power gear difference.

[0101] The temperature control method of the embodiment will be introduced below with specific temperature control logic. The specific temperature control logic of the present embodiment is as follows:

[0102] 1) the user inputs the target temperature T0 in units of ℃;

[0103] 2) Temperature sensor real-time acquisition of the pot bottom temperature (unit ℃), weight sensor real-time acquisition of the pot weight G (unit kg);

[0104] 3) Controller calculates T1(G) = A1 + B1*G and T2(G) = A2 + B2*G according to the formula;

[0105] 4) When T ∈ (-∞, T0-T1(G)), the fire automatically switches to the highest gear (for example: 9 gears), at this time the gas stove heats at the highest heating efficiency;

[0106] 5) When T ∈ (T0-T1(G), T0-T2(G)), the fire automatically switches to the middle gear (for example: 5 gears), at this time the gas stove appropriately reduces the heating efficiency, heats the pot and food, and maintains the temperature to continue to rise;

[0107] 6) When T ∈ (T0-T2(G), T0(G)), the fire is automatically further reduced (for example: 2 gears), at this time the gas stove further reduces the heating efficiency, heats the pot and food, and maintains the temperature to continue to rise;

[0108] 7) When T ∈ (T0, +∞), the fire is automatically adjusted to the lowest gear (i.e. 1 gear), at this time the temperature has reached the target temperature T0, the gas stove reduces the heating efficiency to the lowest, and the pot and food basically play the role of maintaining the current temperature.

[0112] In the embodiment, the device first detects the total weight of the pot and the food inside the pot on the gas stove by using the weight sensor through the total weight acquisition module, and acquires the bearing total weight; secondly, the preset fire power adjustment node temperature is determined according to the bearing total weight of the gas stove through the temperature interval determination module, and at least three temperature intervals are obtained by taking the fire power adjustment node temperature and the target temperature under the current cooking program of the gas stove as the interval segmentation point; wherein the fire power adjustment node temperature under different bearing total weights is different, and the fire power adjustment node temperature is less than the target temperature; then the real-time temperature of the pot is detected by using the temperature sensor through the temperature acquisition module; finally, the fire power level of the gas stove is adjusted in real time according to the temperature interval in which the real-time temperature of the pot is located through the fire power adjustment module; wherein the closer the temperature interval in which the real-time temperature of the pot is located to the target temperature, the lower the fire power level of the gas stove. The embodiment provides a temperature control device for a gas stove, which can set temperature intervals according to the total weight of the food, and set the corresponding fire power according to the temperature interval in which the real-time temperature is located, so as to accurately control the fire power, avoid excessive or too small fire power, ensure the cooking effect, and more efficiently heat, which helps to reduce and save the cooking time.

[0113] Further, the temperature interval determination module 200 comprises: a node temperature calculation unit, configured to calculate the fire power adjustment node temperature according to the fitting function of the fire power adjustment node temperature and the bearing total weight and the bearing total weight of the gas stove; wherein the fitting function of the fire power adjustment node temperature and the bearing total weight is fitted from the relationship curve between the fire power adjustment node temperature and the bearing total weight under different bearing total weights obtained by experiment.

[0114] Based on the above technical scheme, the node temperature calculation unit can be specifically used for calculating the firepower adjustment node temperature T(G) according to the preset first-order linear fitting function T(G) = A*G + B of the firepower adjustment node temperature and the total load weight and the total load weight G of the gas stove; wherein A and B are respectively the first-order term coefficient and the zero-order term coefficient obtained by performing first-order linear fitting on the relationship curve between the firepower adjustment node temperature and the total load weight under different total load weights obtained through experiments.
