[0002] In the field of cooking, gas grills have attracted widespread attention in cooking scenarios such as homes, restaurants, and eateries due to their high efficiency, convenience, diverse cooking types, and adjustability. Gas grills are usually composed of a burner, a gas supply system, a temperature control device, and a food heating area. Its working principle is based on combustion theory, and it achieves heat conduction and heat transfer to food by controlling gas flow and flame temperature. Specifically, the burner can mix gas and air in a certain proportion, generate flames through combustion, and thus heat the food.

[0003] In the temperature control scheme of related gas ovens, manual control is usually adopted. However, for gas ovens with multiple burners, users often need to operate each burner separately. This control method can easily cause temperature differences in the oven during the heating process, that is, the temperature distribution of each point in the oven space is uneven, resulting in poor temperature uniformity in the oven heating process, affecting the final cooking effect of the food. Summary of the invention

[0007] Based on the comparison result between the real-time temperature and the set temperature, a target area satisfying the temperature adjustment condition is determined in the control area;

[0008] A target control strategy matching the comparison result is determined in the preset control strategy, and the firepower of the burner corresponding to the target area is controlled based on the target control strategy to control the real-time temperature of the target area.

[0009] In an embodiment of the present invention, the real-time temperature corresponding to each control area in the oven cavity of the oven can be obtained first, and based on the comparison result between the real-time temperature and the set temperature, the target area that meets the temperature adjustment conditions can be determined in the control area. Then, the target control strategy that matches the comparison result can be determined in the preset control strategy, and the burner corresponding to the target area can be controlled based on the target control strategy to control the real-time temperature of the target area, thereby realizing automatic control of the oven temperature, and according to the comparison result between the real-time temperature and the set temperature, the temperature of the target area is controlled in time to avoid a large temperature difference between different control areas in the oven cavity, thereby realizing uniform heating in the oven cavity and significantly improving the final cooking effect of the food. At the same time, since the present invention only needs to control some burners corresponding to the target area for real-time temperature control without unified regulation of all burners, a more reasonable allocation and full use of the switches of each burner can be made to realize fine-grained control of the burner.

[0010] In an optional embodiment, the target area includes: a target temperature rise area; based on the comparison result between the real-time temperature and the set temperature, determining the target area that meets the temperature adjustment condition in the control area includes:

[0012] The control area in the control area where the difference exceeds the preset threshold is determined as the target temperature increase area that meets the temperature adjustment condition.

[0013] In an embodiment of the present invention, an area in the control area where the difference between the real-time temperature and the set temperature exceeds a preset threshold can be determined as a target temperature rise area, and the first burner corresponding to the target temperature rise area can be adjusted to a first opening degree, so that the control area with a lower temperature can heat up faster, so as to more finely control the gas grill to achieve uniform heating.

[0014] In an optional embodiment, the burner includes: a first burner matching the target temperature increase area;

[0020] Determine the difference between the real-time temperature and the set temperature in each control area;

[0021] The control area in the control area where the difference does not exceed the preset threshold is determined as the target temperature control area that meets the temperature adjustment condition.

[0022] In the embodiment of the present disclosure, the control valve opening of the burner in the target temperature control area can be adjusted to a second opening to reduce the burner firepower in the target temperature control area, thereby realizing the heat preservation function considered by the gas.

[0027] In the disclosed embodiment, the control valve opening of the burner in the target temperature control area can be adjusted to a second opening to reduce the burner firepower in the target temperature control area, thereby realizing the heat preservation function considered by the gas. At the same time, if the second burner overlaps with the first burner, the overlapping burner in the second burner can be determined as the first burner to ensure the heating rate of the target temperature rising area, thereby improving the temperature control efficiency of the gas oven.

[0031] If yes, the coincident burner is adjusted to the second opening, and the non-coincident burner in the target control area is closed;

[0032] If not, all burners in the target control area are adjusted to the second opening degree.

[0033] In the embodiment of the present invention, based on the comparison result between the set temperature and the preset temperature, the coincident burner can be determined as the open burner, and the non-coincident burner can be closed to reduce energy consumption while maintaining the temperature in the furnace chamber stable.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0055] In conjunction with the application scenarios on which the execution of the oven temperature control method depends, the application scenarios are described here.

[0056] In the field of cooking, gas grills have attracted widespread attention in cooking scenarios such as homes, restaurants, and eateries due to their high efficiency, convenience, diverse cooking types, and adjustability. Gas grills are usually composed of a burner, a gas supply system, a temperature control device, and a food heating area. Its working principle is based on combustion theory, and it achieves heat conduction and heat transfer to food by controlling gas flow and flame temperature. Specifically, the burner can mix gas and air in a certain proportion, generate flames through combustion, and thus heat the food.

[0057] In the temperature control scheme of related gas ovens, manual control is usually adopted. However, for gas ovens with multiple burners, users often need to operate each burner separately. This control method can easily cause temperature differences in the oven during the heating process, that is, the temperature distribution of each point in the oven space is uneven, resulting in poor temperature uniformity in the oven heating process, affecting the final cooking effect of the food.

[0058] For example, in the temperature control scheme of a gas oven, when considering temperature control of gas, if the gas oven includes multiple burners, each burner corresponds to an independent temperature control device, the user can manually adjust each temperature control device to control the firepower of at least one burner to achieve temperature increase. However, since there is a temperature difference when the user operates the burner individually, and the firepower of each burner is also different, this control method is very likely to cause a temperature difference in the oven during the heating process, that is, the temperature distribution of each point in the oven space is uneven, resulting in poor temperature uniformity in the oven, affecting the final cooking effect of the food.

[0059] Based on this, an embodiment of the present invention provides an oven temperature control method, which can first obtain the real-time temperature corresponding to each control area in the oven cavity of the oven, and based on the comparison result of the real-time temperature and the set temperature, determine the target area that meets the temperature adjustment conditions in the control area, and then, determine the target control strategy that matches the comparison result in the preset control strategy, and control the burner corresponding to the target area based on the target control strategy to control the real-time temperature of the target area, thereby realizing automatic control of the oven temperature, and according to the comparison result of the real-time temperature and the set temperature, timely control the temperature of the target area to avoid a large temperature difference between different control areas in the oven cavity, thereby realizing uniform heating in the oven cavity and significantly improving the final cooking effect of the food. At the same time, since the present invention only needs to control some burners corresponding to the target area for real-time temperature control without the need to perform the same regulation on all burners, a more reasonable allocation and full use of the switches of each burner can be achieved to realize fine-grained control of the burner.

[0060] According to an embodiment of the present invention, an oven temperature control method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0061] In this embodiment, a method for controlling the temperature of an oven is provided, which can be used in the above-mentioned gas oven. Figure 1 is a flow chart of a method for controlling oven temperature according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0062] Step S101, obtaining the real-time temperature corresponding to each control area in the oven cavity of the oven, wherein each control area corresponds to a temperature sensor for monitoring the real-time temperature and at least two burners for controlling the real-time temperature, and the number of burners corresponding to each control area is the same.

[0063] In an embodiment of the present invention, the oven may be the above-mentioned gas oven, in which a plurality of control areas may be pre-divided so that the temperature of each control area can be controlled separately during the heating process to achieve uniform heating of the gas oven.

[0064] Specifically, when setting the temperature control area in the furnace cavity, the area between two adjacent burners can be determined as the control area, and a temperature probe is set in each control area to obtain the real-time temperature corresponding to the control area.

[0065] For example, if Figure 2The figure shows a schematic diagram of a gas oven structure, in which three burners and two temperature probes can be pre-installed in the oven cavity of the gas oven. Therefore, the area between burner 1 and burner 2 can be determined as control area 1, and the area between burner 2 and burner 3 can be determined as control area 2. Then, the real-time temperature Ta1 of control area 1 can be collected through temperature probe 1, and the real-time temperature Ta2 of control area 2 can be collected through temperature probe 2.

[0066] In addition, such as Figure 3 The schematic diagram of another gas oven structure is shown, in which 4 burners and 3 temperature probes can be pre-set in the oven cavity of the gas oven. Therefore, the area between burner 4 and burner 5 can be determined as control area 3, the area between burner 5 and burner 6 can be determined as control area 4, and the area between burner 6 and burner 7 can be determined as control area 5. Then, the real-time temperature Ta3 of control area 3 can be collected by temperature probe 3, the real-time temperature Ta4 of control area 4 can be collected by temperature probe 4, and the real-time temperature Ta5 of control area 5 can be collected by temperature probe 5.

[0067] Step S102: Based on the comparison result between the real-time temperature and the set temperature, a target area satisfying the temperature adjustment condition is determined in the control area.

[0068] In the embodiment of the present invention, the set temperature Ts may be a target temperature for heating set by the user, and the temperature adjustment condition may include a preset threshold value Tn, for example, Tn may be set to 10°C. Here, the set temperature Ts should be higher than the real-time temperature Ta, and therefore, the comparison result T between the real-time temperature and the set temperature may be expressed as Ts-Ta. When it is determined that the comparison result T>Tn corresponding to any control area in the oven cavity of the gas oven is Ts, the control area may be considered as the target area that meets the temperature adjustment condition. Alternatively, when T≤Tn, if the set temperature is higher than the regional temperature threshold, all control areas may be considered as the target areas that meet the temperature adjustment condition.

[0069] Here the above Figure 2 Taking the gas oven shown in as an example, the comparison result corresponding to control area 1 is T1, and the real-time temperature is Ta1, and the comparison result corresponding to control area 2 is T2, and the real-time temperature is Ta2. Here, T1 and T2 can be calculated in real time during the heating process of the gas oven, and T1, T2 and Tn can be compared respectively to obtain the target area.

[0070] Step S103, determining a target control strategy that matches the comparison result in the preset control strategy, and controlling the firepower of the burner corresponding to the target area based on the target control strategy to control the real-time temperature of the target area.

[0071] In the embodiment of the present invention, a corresponding control strategy can be set according to the number and position of the target area and the corresponding comparison result. Specifically, the burner corresponding to the target area can be determined according to the number and position of the target area, and then the firepower of the burner corresponding to the target area can be adjusted according to the comparison result.

[0072] Here the above Figure 2 Taking the gas grill shown in as an example, if control area 1 is the target area, the preset control strategy 1 can be determined as the target control strategy. Specifically, the target control strategy can determine burner 1 and burner 2 as the burners corresponding to the target area. Since the comparison result is T1>Tn, the firepower of burner 1 and burner 2 can be adjusted to the maximum.

[0073] It should be understood that in order to ensure that the temperature rise amplitude between the non-target area and the target area is slightly different, thereby achieving uniform temperature rise, when adjusting the real-time temperature of the target area through the target control strategy, the burner corresponding to the non-target area can be intelligently adjusted, for example, adjusted to a low fire state.

[0074] In summary, in an embodiment of the present invention, the real-time temperature corresponding to each control area in the oven cavity of the oven can be first obtained, and based on the comparison result between the real-time temperature and the set temperature, the target area that meets the temperature adjustment conditions can be determined in the control area. Then, a target control strategy that matches the comparison result can be determined in the preset control strategy, and the burner corresponding to the target area can be controlled based on the target control strategy to control the real-time temperature of the target area, thereby realizing automatic control of the oven temperature, and according to the comparison result between the real-time temperature and the set temperature, the temperature of the target area is timely controlled to avoid a large temperature difference between different control areas in the oven cavity, thereby realizing uniform heating in the oven cavity and significantly improving the final cooking effect of the food. At the same time, since the present invention only needs to control some burners corresponding to the target area for real-time temperature control without the need to perform the same regulation on all burners, a more reasonable allocation and full use of the switches of each burner can be achieved to realize fine-grained control of the burner.

[0075] In some optional embodiments, the target area includes: a target temperature rise area, and the step S102 determines the target area that meets the temperature adjustment condition in the control area based on the comparison result between the real-time temperature and the set temperature, including:

[0076] Step S11, determining the difference between the real-time temperature and the set temperature in each control area.

[0077] Step S12: determining the control area in the control area where the difference exceeds the preset threshold as the target temperature increase area that meets the temperature adjustment condition.

[0078] In an embodiment of the present invention, the difference T between the real-time temperature Ta and the set temperature Ts is T=Ts-Ta, and the preset threshold is the above-mentioned Tn. Here, Ta and Ts can be compared in real time, and the control area of ​​the oven where T>Tn is determined as the target temperature rise area.

[0079] Specifically, after the target temperature rise area is determined, the burner corresponding to the target area includes: a first burner matching the target temperature rise area. After the first burner is determined, the above step S103, based on the target control strategy, controls the firepower of the burner corresponding to the target area, including:

[0080] Step S21, determining a first burner in the furnace cavity that matches the target temperature rising area based on the associated information.

[0081] Step S22: Based on the target control strategy, the control valve opening corresponding to the first burner is adjusted to a first opening.

[0082] In the embodiment of the present invention, the first burner may be a burner located on both sides of the target temperature rise area. For example, if the target temperature rise area is the control area 1, the first burner may be the burner 1 and the burner 2. The association information may include an association relationship between the control area and the corresponding burner. For example, the control area 1 corresponds to the burner 1 and the burner 2, and the control area 2 corresponds to the burner 2 and the burner 3. It should be understood that the association relationship included in the association information may be adjusted to meet the temperature control requirements of the user.

[0083] Here, if Figure 4 Shown above Figure 2 The temperature control flow chart of the gas oven. Figure 4 It can be seen that when T1>Tn, T2≤Tn, control area 1 is the target temperature rise area, and the first burner corresponding to the target temperature rise area may include burner 1 and burner 2. At this time, the opening of control valve 1 corresponding to burner 1 and control valve 2 corresponding to burner 2 can be adjusted to a first opening, wherein the first opening can be a maximum opening so that burner 1 and burner 2 can work at high fire.

[0084] In addition, when T2>Tn, T1≤Tn, control area 2 is the target temperature rise area, and the first burner corresponding to the target temperature rise area may include burner 2 and burner 3. At this time, the opening of control valve 2 corresponding to burner 2 and control valve 3 corresponding to burner 3 can be adjusted to the maximum opening to make burner 2 and burner 3 work at high fire.

[0085] In addition, when T2>Tn, T1>Tn, control area 1 and control area 2 can both be determined as target temperature rise areas. The first burner corresponding to the target temperature rise area can be all the burners in the gas grill, namely burner 1, burner 2 and burner 3. At this time, the opening of control valve 1-control valve 3 can be adjusted to the maximum opening so that all burners can work at high fire.

[0086] In an embodiment of the present invention, an area in the control area where the difference between the real-time temperature and the set temperature exceeds a preset threshold can be determined as a target temperature rise area, and the first burner corresponding to the target temperature rise area can be adjusted to a first opening degree, so that the control area with a lower temperature can heat up faster, so as to more finely control the gas grill to achieve uniform heating.

[0087] In some optional embodiments, the target area includes: a target temperature control area, and the step S102, based on the comparison result between the real-time temperature and the set temperature, determines the target area that meets the temperature adjustment condition in the control area, and further includes:

[0088] Step S31, determining the difference between the real-time temperature and the set temperature in each control area.

[0089] Step S32: determine the control area whose difference does not exceed the preset threshold value as the target temperature control area that meets the temperature adjustment condition.

[0090] In the embodiment of the present invention, the target temperature control area is used to indicate the control area where the temperature in the gas oven is close to the set temperature Ts and needs to be kept warm during the heating process. Here, the control area of ​​the gas oven where T≤Tn can be determined as the target heating area.

[0091] Specifically, after the target temperature control area is determined, the burner corresponding to the target area includes: a second burner matching the target temperature control area. After the second burner is determined, the above step S103, controlling the firepower of the burner corresponding to the target area based on the target control strategy, also includes:

[0092] Step S41, determining a second burner in the furnace cavity that matches the target temperature control area based on the associated information.

[0093] Step S42, when the first burner and the second burner overlap, the overlapping burner is only classified into the first burner, and based on the target control strategy, the control valve opening corresponding to the second burner is adjusted to a second opening, wherein the second opening is smaller than the first opening.

[0094] In the embodiment of the present invention, the second burner may be a burner located on both sides of the target temperature control area. For example, if the target temperature control area is the control area 3, the second burner may be the burner 4 and the burner 5. The association information may include an association relationship between the control area and the corresponding burner. For example, the control area 4 corresponds to the burner 5 and the burner 6, and the control area 5 corresponds to the burner 6 and the burner 7.

[0095] It should be understood that a gas oven usually includes both a heating area and a temperature control area during the heating process. In order to ensure the heating rate of the heating area to improve the temperature control efficiency, if the second burner overlaps with the first burner, the overlapping burner can be determined as the first burner.

[0096] Here Figure 4 For example, when T2>Tn, T1≤Tn, control area 2 is the target temperature rise area, and the first burner corresponding to the target temperature rise area may include burner 2 and burner 3. The target temperature control area is control area 1, and the second burner corresponding to the target temperature control area may include burner 1 and burner 2. At this time, burner 2 can be determined as the first burner to adjust the opening of control valve 2 corresponding to burner 2 and control valve 3 corresponding to burner 3 to the maximum opening, so that burner 2 and burner 3 can work at high fire.

[0097] It should be understood that when the control area of ​​the gas grill is greater than or equal to 3, if the second burner overlaps with the first burner, it can be determined whether to determine the second burner as the first burner according to the position of the first burner. For example, if one side of the target temperature increase area is located at the side of the gas grill, the second burner may not be determined as the first burner to save energy.

[0098] Specifically, Figure 5 Shown above Figure 3 The temperature control flow chart of the gas oven. Figure 5 It can be seen that when T3≤Tn, T4≤Tn, T5>Tn, control area 3 and control area 4 are target temperature control areas, and the second burner corresponding to the target temperature control area may include burner 4, burner 5 and burner 6, which overlap with burner 6 and burner 7 in the first burner corresponding to the target temperature rise area. At this time, since the target temperature rise area is control area 5, Figure 2It can be seen that the control area 5 is located on the right side of the gas grill, so the second burner is still burner 4, burner 5 and burner 6, and the openings of control valve 4, control valve 5 and control valve 6 can be adjusted to the second opening to make burner 4, burner 5 and burner 6 work at a low flame. It should be understood that the second opening can be intelligently adjusted, that is, the second opening can be any opening less than the first opening, so as to keep the difference T between the real-time temperature corresponding to the target temperature control area and the set temperature less than or equal to the preset threshold value Tn.

[0099] In addition, when T3≤Tn, T4>Tn, T5≤Tn, control areas 3 and 5 are target temperature control areas, and the second burners corresponding to the target temperature control areas may include burners 4, burners 5, burners 6 and burners 7, wherein, since burners 5 and burners 6 overlap with the first burner, burners 5 and burners 6 can be determined as the first burners, and the opening of control valve 4 corresponding to burner 4 and control valve 7 corresponding to burner 7 are adjusted to the second opening, so that burners 4 and burners 7 work at low fire.

[0100] In addition, when T3≤Tn, T4>Tn, T5>Tn, control area 3 is the target temperature control area, the second burner includes burner 4 and burner 5, and the control areas 4 and 5 corresponding to the target temperature rise area are located on the right side of the gas oven, so the second burner is not adjusted. At this time, the opening of the control valve 4 corresponding to the burner 4 and the control valve 5 corresponding to the burner 5 can be adjusted to the second opening, so that the burner 4 and the burner 5 work at a low fire.

[0101] In addition, when T3>Tn, T4≤Tn, T5>Tn, control area 4 is the target temperature control area, and the second burner includes burner 5 and burner 6. Since control area 3 corresponding to the target temperature rise area is located on the left side of the gas oven, and control area 5 corresponding to the target temperature rise area is located on the right side of the gas oven, the second burner is not adjusted. At this time, the opening of control valve 5 corresponding to burner 5 and control valve 6 corresponding to burner 6 can be adjusted to the second opening, so that burner 5 and burner 6 work at a low flame.

[0102] In addition, when T3>Tn, T4>Tn, T5≤Tn, control area 5 is the target temperature control area, the second burner includes burner 6 and burner 7, and control areas 3 and 4 corresponding to the target temperature rise area are located on the left side of the gas oven, so the second burner is not adjusted. At this time, the opening of control valve 6 corresponding to burner 6 and control valve 7 corresponding to burner 7 can be adjusted to the second opening, so that burner 6 and burner 7 work at a low flame.

[0103] In addition, when T3>Tn, T4>Tn, T5>Tn, there is no target temperature control area in the gas oven. At this time, the openings of the control valves corresponding to all burners can be adjusted to the maximum openings to make all burners work at high fire.

[0104] In the disclosed embodiment, the control valve opening of the burner in the target temperature control area can be adjusted to a second opening to reduce the burner firepower in the target temperature control area, thereby realizing the heat preservation function considered by the gas. At the same time, if the second burner overlaps with the first burner, the overlapping burner in the second burner can be determined as the first burner to ensure the heating rate of the target temperature rising area, thereby improving the temperature control efficiency of the gas oven.

[0105] In some optional embodiments, the target temperature control area includes all control areas, and the step S103 of controlling the firepower of the burner corresponding to the target area based on the target control strategy further includes:

[0106] Step S51, when all control areas are determined as target control areas, a preset temperature is obtained, and it is determined whether the set temperature is lower than the preset temperature. If so, step S52 is executed, and if not, step S53 is executed.

[0107] Step S52, adjusting the overlapping burner to a second opening degree, and closing the non-overlapping burner in the target control area.

[0108] Step S53, adjusting all burners in the target control area to the second opening degree.

[0109] In the embodiment of the present disclosure, if the difference between the real-time temperature and the set temperature in all control areas in the gas oven does not exceed the preset threshold value, it is determined that the gas oven enters the temperature control state. At this time, the burners corresponding to some control areas can be turned off so that the real-time temperature in the gas oven can be maintained within the set temperature range while saving energy.

[0110] Specifically, multiple temperature intervals can be pre-set, and a corresponding number of burners sufficient to maintain the temperature interval can be set for each temperature interval, so that when the set temperature Ts hits the target temperature interval, the control valve opening of the open burner can be controlled. For example, the open burner can be an overlapping burner between the second burner and the first burner. Here, the temperature interval can be determined based on the preset temperature. Specifically, if the preset temperature interval is 279°C, the temperature interval can be divided into a first temperature interval and a second temperature interval, wherein the first temperature interval can be expressed as [0, 270), and the second temperature interval can be expressed as [270, the highest set temperature n]. It should be understood that the higher the temperature of the temperature interval, the more burners are opened.

[0111] For example, Figure 4 As shown, when T1≤Tn, T2≤Tn, if Ts is lower than the preset temperature and belongs to the first temperature interval, the corresponding open burner includes burner 2. At this time, the control valve 2 corresponding to burner 2 can be set to intelligent opening adjustment, and the control valves corresponding to burner 1 and burner 3 can be closed to extinguish burner 1 and burner 3, thereby maintaining temperature stability. If Ts is higher than the preset temperature and belongs to the second temperature interval, the corresponding open burners include burner 1-burner 3. At this time, the control valves corresponding to burner 1-burner 3 can be set to intelligent opening adjustment, thereby maintaining temperature stability.

[0112] For example, Figure 5 As shown, when T3≤Tn, T4≤Tn, T5≤Tn, if Ts is lower than the preset temperature and belongs to the first temperature range, the corresponding open burners include burner 5 and burner 6. At this time, the control valves corresponding to burner 5 and burner 6 can be set to intelligent opening adjustment, and the control valves corresponding to burner 4 and burner 7 can be closed to extinguish burner 4 and burner 7, thereby maintaining temperature stability. If Ts is higher than the preset temperature and belongs to the second temperature range, the corresponding open burners include burner 4-burner 7. At this time, the control valves corresponding to burner 4-burner 7 can be set to intelligent opening adjustment, thereby maintaining temperature stability.

[0113] In an embodiment of the present invention, based on the comparison result between the set temperature and the preset temperature, the overlapping burner can be determined as the turned-on burner, and other burners of the non-overlapping burner can be turned off to reduce energy consumption while maintaining the temperature in the furnace chamber stable.

[0114] In summary, in the embodiments of the present invention, the real-time temperatures corresponding to each control area in the oven cavity of the oven can be first obtained, and based on the comparison result between the real-time temperature and the set temperature, the target area that meets the temperature adjustment conditions can be determined in the control area. Then, the target control strategy that matches the comparison result can be determined in the preset control strategy, and the burner corresponding to the target area can be controlled based on the target control strategy to control the real-time temperature of the target area, thereby realizing automatic control of the oven temperature, and according to the comparison result between the real-time temperature and the set temperature, the temperature of the target area can be controlled in time to avoid a large temperature difference between different control areas in the oven cavity, thereby realizing uniform heating in the oven cavity and significantly improving the final cooking effect of the food. At the same time, since the present invention only needs to control some of the burners corresponding to the target area for real-time temperature control, it is more reasonable to allocate and fully utilize the switches of each burner, and there is no need to perform the same regulation on all burners to realize fine-grained control of the burners.
