Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, specifically to a temperature control method, device, oven, and storage medium for an oven. Background Technology

[0002] In outdoor barbecue and other similar scenarios, traditional outdoor gas grills primarily rely on manual adjustment of the heat output, while temperature control depends mainly on the user's experience or on monitoring the real-time temperature using a mechanical thermometer, and then adjusting the heat output based on the measured real-time temperature.

[0003] However, this manual operation method has a low level of intelligence, resulting in significant uncertainty in the final temperature. Inaccurate heat adjustment leads to uncontrollable temperature, lacking precise temperature control. Furthermore, manual adjustment is often inefficient when rapid temperature adjustment is required, failing to meet user needs. Summary of the Invention

[0004] In view of this, the present invention provides a method, apparatus, oven and storage medium for controlling the temperature of an oven, in order to solve the problems of insufficient precision and low efficiency in adjusting the temperature of an oven.

[0005] In a first aspect, the present invention provides a method for controlling the temperature of an oven, the method comprising:

[0006] Upon detecting a temperature control request, the set temperature is obtained, and the current temperature of the oven is also obtained in real time.

[0007] Based on the current temperature and the set temperature, determine the current combustion stage of the oven;

[0008] If the combustion stage is in the heating stage, then all burners are controlled to burn;

[0009] If the combustion stage is not in the heating stage, a preset temperature is obtained, and the corresponding target burner is controlled to perform combustion based on the comparison result between the set temperature and the preset temperature.

[0010] The oven temperature control method of this invention can acquire the set temperature and the oven's current temperature in real time after detecting a temperature control request. Next, based on the current temperature and the set temperature, it can determine the current combustion stage of the oven. If the combustion stage is the heating stage, all burners are controlled to ignite. Alternatively, if the combustion stage is not the heating stage, a preset temperature is acquired, and based on the comparison between the set temperature and the preset temperature, the corresponding target burner is controlled to ignite. This achieves automated oven temperature control, improves the accuracy of heat adjustment, and thus improves the efficiency of temperature regulation.

[0011] In some optional implementations, based on the comparison result between the set temperature and the preset temperature, a corresponding target burner is determined for combustion, including:

[0012] If the set temperature is not lower than the preset temperature, then all burners will be controlled to burn.

[0013] If the set temperature is lower than the preset temperature, then control part of the burner to burn.

[0014] In some optional implementations, the temperature control request includes a heating request and a cooling request; obtaining the preset temperature includes:

[0015] The preset temperature is determined based on the type of the temperature control request;

[0016] If the temperature control request is a heating request, then the preset temperature is the first preset temperature;

[0017] If the temperature control request is a cooling request, then the preset temperature is the second preset temperature;

[0018] The first preset temperature is greater than the second preset temperature.

[0019] In some optional implementations, the difference between the first preset temperature and the second preset temperature is not less than 20°C.

[0020] In some alternative implementations, the combustion phase includes a heating phase, a cooling phase, and a isothermal phase;

[0021] The statement that if the set temperature is not lower than the preset temperature, then controlling all burners to ignite includes:

[0022] If the combustion stage is in the constant temperature stage, all burners are controlled to automatically adjust their power according to the current temperature and the set temperature. If the combustion stage is in the cooling stage, all burners are controlled to burn at the first preset power.

[0023] The step of controlling part of the burner to ignite if the set temperature is lower than the preset temperature includes:

[0024] If the combustion stage is in the constant temperature stage, the control part of the burner automatically adjusts the power according to the current temperature and the set temperature. If the combustion stage is in the cooling stage, the control part of the burner burns at the first preset power.

[0025] In some optional implementations, if the combustion phase is in the heating phase, then all burners are controlled to ignite, including:

[0026] If the combustion stage is in the heating stage, then all burners are controlled to burn at a second preset power, wherein the second preset power is greater than the first preset power.

[0027] In some optional implementations, determining the current combustion stage of the oven based on the current temperature and the set temperature includes:

[0028] If the temperature control request is a heating request, when the current temperature is lower than the set temperature by a value greater than the first threshold, the current combustion stage of the oven is the heating stage; when the current temperature is lower than the set temperature by a value less than the first threshold, the current combustion stage of the oven is the constant temperature stage.

[0029] If the temperature control request is a cooling request, when the current temperature has not reached the set temperature, the current combustion stage of the oven is a cooling stage; when the current temperature reaches the set temperature, the current combustion stage of the oven is a constant temperature stage.

[0030] In a second aspect, the present invention provides a temperature control device for an oven, the device comprising:

[0031] The acquisition module is used to acquire the set temperature after detecting a temperature control request, and to acquire the current temperature of the oven in real time;

[0032] The judgment module is used to determine the current combustion stage of the oven based on the current temperature and the set temperature;

[0033] The first control module is used to control all burners to burn if the combustion stage is in the heating stage;

[0034] The second control module is used to obtain a preset temperature if the combustion stage is not in the heating stage, and control the corresponding target burner to perform combustion based on the comparison result between the set temperature and the preset temperature.

[0035] Thirdly, the present invention provides an oven, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the temperature control method described in the first aspect or any corresponding embodiment thereof.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The application scenarios on which the temperature control method depends are described here.

[0047] In outdoor barbecue and other similar scenarios, traditional outdoor gas grills primarily rely on manual adjustment of the heat output, while temperature control depends mainly on the user's experience or on monitoring the real-time temperature using a mechanical thermometer, and then adjusting the heat output based on the measured real-time temperature.

[0048] However, this manual operation method has a low level of intelligence, resulting in significant uncertainty in the final temperature. Inaccurate heat adjustment leads to uncontrollable temperature, lacking precise temperature control. Furthermore, manual adjustment is often inefficient when rapid temperature adjustment is required, failing to meet user needs.

[0049] Based on this, embodiments of the present invention provide a temperature control method for an oven. Upon detecting a temperature control request, a set temperature can be acquired, and the current temperature of the oven can be acquired in real time. Next, based on the current temperature and the set temperature, the current combustion stage of the oven can be determined. If the combustion stage is in the heating stage, all burners are controlled to ignite. Alternatively, if the combustion stage is not in the heating stage, a preset temperature is acquired. Based on the comparison between the set temperature and the preset temperature, the corresponding target burner is controlled to ignite, thereby automating the oven's temperature control, improving the accuracy of heat adjustment, and ultimately improving the efficiency of temperature regulation.

[0050] According to an embodiment of the present invention, a method for controlling the temperature of an oven is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0051] This embodiment provides a method for controlling the temperature of an oven, which can be used for, for example Figure 2 The oven shown... Figure 1 This is a flowchart of a temperature control method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0052] Step S101: After detecting the temperature control request, obtain the set temperature and obtain the current temperature of the oven in real time.

[0053] In this embodiment of the invention, the oven can be the gas oven described above, which includes a temperature control system for adjusting the real-time temperature. The temperature control system includes, but is not limited to, the following components: a display, a parameter setter, a controller, a main valve, a proportional valve, a segmented valve, a temperature sensor, and a burner.

[0054] Specifically, the display shows information such as the set temperature Ts, real-time temperature Ta, and gas cylinder status. The parameter setter is used to set the combustion temperature and other parameters of the gas-fired oven. The burners generate the flame. Here, the gas-fired oven can have at least three burners with independent gas delivery channels. The main burner, typically located in the middle (e.g., burner 2), controls the on / off state of the gas delivery channels via proportional valves. Other gas delivery channels are controlled by sectional valves (e.g., burner 1, burner 3). The controller receives control commands from the parameter setter and controls the on / off state and opening degree of the proportional valves to control the total gas flow. It also controls the on / off state of the sectional valves. During segmented combustion, an algorithm controls the on / off state and opening degree of each sectional valve to adjust the heat intensity within the oven cavity, achieving a constant oven temperature.

[0055] Additionally, the aforementioned controller can integrate an ignition device, a flame detection device, and a temperature sensor. Specifically, the ignition device includes an ignition needle, which can be mounted at the gas outlet of each burner and connected to the integrated ignition device in the controller via a high-voltage ignition wire. The controller controls high-voltage discharge ignition during ignition. The flame detection device includes a feedback needle, mounted at the gas outlet of each burner and connected to the integrated flame detection device in the controller via a connecting wire, feeding back the flame signal to the main controller. The temperature sensor detects the temperature inside the furnace cavity and feeds back the furnace cavity temperature signal to the controller. The controller then sends signals to control the opening degree of the proportional valve and the combined on / off state of the segmented valves.

[0056] Specifically, such as Figure 2 The diagram shows the structure of a gas-fired oven. This oven includes three burners: burner 2 is the main burner, and burners 1 and 3 are auxiliary burners. Specifically, the main valve connects to the main air intake and its output is connected to the proportional valve input via a pipe to control the flow of gas in the main gas duct. The proportional valve's input is connected to the main gas duct, and its output is directly connected to the main burner 2. It is also connected to the input ports of other sectional valves, such as sectional valve 1 and sectional valve 3, to control the total output gas volume and the amount of gas delivered to the main burner 2. The sectional valves control the opening or closing of the burner's gas delivery channels. Their inputs are connected to the proportional valves, and their outputs are directly connected to auxiliary burners 1 and 3. The number of sectional valves matches the number of burners, such as sectional valve 1 and sectional valve 2.

[0057] In this embodiment of the invention, after receiving the temperature control request, the controller of the gas oven can determine the set temperature Ts requested by the temperature control request and obtain the current temperature Ta in the oven cavity in real time.

[0058] Step S102: Based on the current temperature and the set temperature, determine the current combustion stage of the oven.

[0059] Step S103: If the combustion stage is in the heating stage, then control all burners to burn.

[0060] Step S104: If the combustion stage is not in the heating stage, obtain the preset temperature, and control the corresponding target burner to perform combustion based on the comparison result between the set temperature and the preset temperature.

[0061] In this embodiment of the invention, if the set temperature Ts is greater than the current temperature Ta by a certain value, it can be determined that the current combustion stage of the oven is the heating stage. Conversely, if Ts is not greater than Ta by a certain value, it can be determined that the current combustion stage of the oven is not the heating stage.

[0062] Specifically, if the combustion stage of the oven is determined to be the heating stage, all burners can be controlled to burn to accelerate the heating rate. For example, all burners 1 to 3 can be controlled to burn.

[0063] In addition, if it is determined that the combustion stage of the oven is not in the heating stage, the set temperature Ts can be compared with the preset temperature, and the target temperature range can be determined based on the comparison results, so as to control the target burner that matches the target temperature range to burn.

[0064] For example, if the preset temperature is 230℃, when Ts is greater than 230℃, the target temperature range is determined as the first temperature range; when Ts is less than 230℃, the target temperature range is determined as the second temperature range. Considering that the heat demand varies depending on the target temperature range when the oven is not heating up, with the first temperature range requiring higher heat and the second temperature range requiring lower heat, the heat can be controlled by adjusting the number of target burners activated, thereby achieving temperature regulation. Specifically, if the target temperature range is the first temperature range, the target burners can be all burners, i.e., burners 1 through 3. Alternatively, if the target temperature range is the second temperature range, the target controller can be any single burner from burners 1 through 3.

[0065] As described above, in this embodiment of the invention, after detecting a temperature control request, the set temperature can be obtained, and the current temperature of the oven can be obtained in real time. Next, based on the current temperature and the set temperature, the current combustion stage of the oven can be determined. If the combustion stage is in the heating stage, all burners are controlled to ignite. Alternatively, if the combustion stage is not in the heating stage, a preset temperature is obtained, and based on the comparison between the set temperature and the preset temperature, the corresponding target burner is controlled to ignite, thereby automating the oven's temperature control, improving the accuracy of heat adjustment, and ultimately improving the efficiency of temperature regulation.

[0066] In some optional embodiments, step S104 above, which controls the corresponding target burner to perform combustion based on the comparison result between the set temperature and the preset temperature, includes:

[0067] Step S1041: If the set temperature is not less than the preset temperature, then control all burners to burn.

[0068] In step S1042, if the set temperature is lower than the preset temperature, then control part of the burners to burn.

[0069] In this embodiment of the invention, the non-heating stage may include a cooling stage and a temperature control stage. The temperature control stage may be a temperature control stage after heating stage and a temperature control stage after cooling stage. A first preset temperature may be set for the heating stage and the temperature control stage after heating stage, and a second preset temperature may be set for the cooling stage and the temperature control stage after cooling stage.

[0070] Specifically, in this invention, whether in the cooling or temperature control phase, as long as the set temperature Ts is less than the preset temperature, any part of the burners can be controlled to burn. For example, any single burner from burner 1 to burner 3 can be controlled to burn. Conversely, when the set temperature Ts is not less than the preset temperature, all burners from burner 1 to burner 3 must be controlled to burn.

[0071] It should be understood that when setting the first preset temperature and the second preset temperature, the first preset temperature should be greater than the second preset temperature to ensure the temperature control effect and improve the temperature control accuracy.

[0072] In some optional implementations, the temperature control request includes a heating request and a cooling request; step S101, obtaining the preset temperature, includes:

[0073] Step S1011: Determine the preset temperature based on the type of temperature control request.

[0074] Step S1012: If the temperature control request is a heating request, then the preset temperature is the first preset temperature.

[0075] Step S1013: If the temperature control request is a cooling request, then the preset temperature is the second preset temperature, wherein the first preset temperature is greater than the second preset temperature.

[0076] In this embodiment of the invention, a heating request is used to instruct the oven to increase its current set temperature Ts, and a cooling request is used to decrease the oven's current set temperature Ts. Here, considering that the heat requirements for handling different temperature control requests vary depending on the oven's temperature range, a preset temperature can be pre-set for each type of temperature control request.

[0077] Specifically, the preset temperature corresponding to the heating request can be set to the first preset temperature mentioned above, and the preset temperature corresponding to the cooling request can be set to the second preset temperature mentioned above. As can be seen above, the first preset temperature should be greater than the second preset temperature. This avoids the situation where, when repeatedly adjusting the set temperature Ts, all burners ignite when Ts is not less than the preset temperature, and only some burners ignite when Ts is less than the preset temperature. If the set temperature Ts happens to be near the first and second preset temperatures, it can easily cause the burners in the gas oven that did not ignite when Ts was less than the preset temperature to repeatedly ignite and extinguish, producing frequent popping ignition sounds and affecting the user experience.

[0078] Based on this, further ensuring that the difference between the first preset temperature and the second preset temperature is not less than 20°C further guarantees that adjusting the set temperature Ts will not repeatedly ignite and extinguish the burners in the gas oven that are not burning when the set temperature TS is lower than the preset temperature. For example, the preset temperature can be set to 270°C and the second preset temperature can be set to 230°C.

[0079] In some optional embodiments, the combustion stage includes a heating stage, a cooling stage, and a constant temperature stage; in step S1041, if the set temperature is not lower than the preset temperature, all burners are controlled to ignite, including:

[0080] If the combustion stage is in the constant temperature stage, all burners are controlled to automatically adjust their power according to the current temperature and the set temperature. If the combustion stage is in the cooling stage, all burners are controlled to burn at the first preset power.

[0081] Additionally, in step S1042, if the set temperature is lower than the preset temperature, controlling part of the burner to ignite includes:

[0082] If the combustion stage is in the constant temperature stage, the control part of the burner will automatically adjust the power according to the current temperature and the set temperature. If the combustion stage is in the cooling stage, the control part of the burner will burn at the first preset power.

[0083] In this embodiment of the invention, the heating stage can be a cold heating stage, the cooling stage can be the aforementioned hot cooling stage, and the constant temperature stage can be the aforementioned temperature control stage. Here, when the oven is in the constant temperature stage during combustion, the burners in combustion state can be controlled to adaptively adjust the firepower to maintain the current temperature Ta matching the set temperature Ts. Here, the proportional valves or segmented valves corresponding to each burner can be adjusted by automatic power regulation to control the air intake, thereby adjusting the firepower.

[0084] Specifically, during the constant temperature phase, if the set temperature Ts is not less than the preset temperature, all burners (i.e., burners 1 to 3) can be controlled to automatically adjust their power according to the current temperature and the set temperature. Conversely, if the set temperature Ts is less than the preset temperature, a single burner can be controlled to automatically adjust its power according to the current temperature and the set temperature, and extinguish other burners. For example, the main burner (i.e., burner 2 mentioned above) can be controlled to automatically adjust its power and extinguish burners 1 and 3.

[0085] As can be seen from the above, the preset temperatures include a first preset temperature and a second preset temperature. Specifically, regarding the first preset temperature, when controlling the burner to automatically adjust its power during the constant temperature phase, the difference between the current temperature Ta and the set temperature Ts must be less than or equal to 10℃. Furthermore, regarding the second preset temperature, when controlling the burner to automatically adjust its power during the constant temperature phase, the current temperature Ta must reach the set temperature Ts.

[0086] Additionally, if the set temperature is not lower than the preset temperature, and the combustion stage is in the cooling stage, all burners can be controlled to burn at the first preset power. Here, the first preset power can be used to control all burners to burn at a low flame, thereby reducing the current temperature inside the oven while maintaining the set temperature at or above the preset temperature.

[0087] In some optional embodiments, step S103 above, if the combustion stage is in the heating stage, involves controlling all burners to ignite, including:

[0088] If the combustion stage is in the heating stage, then all burners are controlled to burn at the second preset power, where the second preset power is greater than the first preset power.

[0089] In this embodiment of the invention, the second preset power can be used to control all burners to burn at high flame, thereby increasing the heating rate during the heating phase.

[0090] In some optional embodiments, step S102 above, which determines the current combustion stage of the oven based on the current temperature and the set temperature, includes:

[0091] Step S1021: If the temperature control request is a heating request, when the current temperature is lower than the set temperature by a value greater than the first threshold, the current combustion stage of the oven is the heating stage; when the current temperature is lower than the set temperature by a value less than the first threshold, the current combustion stage of the oven is the constant temperature stage.

[0092] Step S1022: If the temperature control request is a cooling request, the oven is currently in a cooling stage when the current temperature has not reached the set temperature, and the oven is currently in a constant temperature stage when the current temperature has reached the set temperature.

[0093] In embodiments of the present invention, such as Figure 3 The flowchart shown is a temperature control method corresponding to a heating request. The first temperature range can be a set temperature Ts that is less than the first preset temperature, the second temperature range can be a set temperature Ts that is greater than the first preset temperature, the first threshold can be 10℃, and the second threshold can be 50℃.

[0094] Specifically, the first step is to determine whether the condition Ts - current temperature Ta ≥ 50℃ holds true.

[0095] If not, the valves to be adjusted can be determined based on the temperature range in which Ts is located, in order to improve temperature control accuracy. For example, when Ts is in the first temperature range, the required heat output is relatively small, so the proportional valve opening can be automatically adjusted to adjust only the heat output of burner 2. Conversely, when Ts is in the second temperature range, the required heat output is relatively large, so the proportional valve and the sectional valve openings can be automatically adjusted to regulate the heat output of burners 1, 2, and 3.

[0096] If so, the valve openings of the segmented valve and the proportional valve are opened to the maximum, and it is further determined whether Ts-Ta is less than 10℃. If so, the current combustion stage of the oven is determined to be the constant temperature stage, and the proportional valve opening is automatically adjusted to maintain temperature stability. If not, the current combustion stage of the oven is determined to be the constant temperature rise stage, and the valve openings of the segmented valve and the proportional valve are opened to the maximum to increase the heating rate.

[0097] In embodiments of the present invention, such as Figure 4 The flowchart shown is a temperature control method corresponding to a cooling request. The third temperature range can be a set temperature Ts that is less than the second preset temperature, and the fourth temperature range can be a set temperature Ts that is greater than the second preset temperature.

[0098] Here, when Ts is in the third temperature range, a single burner can first be set to operate at low flame, and it is determined whether the current temperature Ta has reached Ts. If so, the current combustion stage of the oven is determined to be the constant temperature stage, and the power of the single burner is automatically adjusted to maintain a stable temperature. If not, the current combustion stage of the oven is determined to be the cooling stage, and the single burner continues to operate at low flame. Conversely, when Ts is in the fourth temperature range, all burners can first be set to operate at low flame, and it is determined whether the current temperature Ta has reached Ts. If so, the current combustion stage of the oven is determined to be the constant temperature stage, and the power of all burners is automatically adjusted to maintain a stable temperature. If not, the current combustion stage of the oven is determined to be the cooling stage, and all burners continue to operate at low flame.

[0099] In some alternative implementations, the above Figure 1The corresponding implementation methods also include:

[0100] Step S11: Based on preset association information, determine the burner group that matches the target temperature range, wherein the preset association information is used to indicate the association relationship between the burner group and the corresponding set temperature.

[0101] Step S12: Determine the target burner that matches the temperature control request based on the burner group.

[0102] In this embodiment of the invention, the oven has at least three burners. A proportional valve directly controls the gas supply to one burner, which can be called the main burner. Each auxiliary burner has an independent sectional valve that directly controls its gas supply. Thus, the main burner and the other burners can be arbitrarily combined to form a burner. Figure 2 Taking a gas-fired oven as an example, we can obtain burner combination 1 (burner 2 and burner 1), burner combination 2 (burner 2 and burner 3), and burner combination 3 (burner 2, burner 1, and burner 3).

[0103] Each burner group has a minimum and maximum firepower corresponding to the minimum and maximum opening of the proportional valve, respectively. The minimum and maximum firepower correspond to a minimum and maximum combustion temperature, respectively. Thus, each group corresponds to a range of combustion temperatures.

[0104] Within the combustion temperature range corresponding to each combination, the proportional valve opening is divided into several equal parts between the minimum and maximum opening. Each part is regarded as a unit opening value. Thus, with the minimum opening of the proportional valve as the base point, each unit opening above it can generate a combustion firepower and a corresponding combustion temperature. Therefore, within this combustion temperature range, the combustion temperature can be controlled to be infinitely linearly adjusted between the minimum and maximum temperatures in this range.

[0105] Here, the proportional valve opening is achieved by current drive. One drive current corresponds to one proportional valve opening. Therefore, dividing the opening into several equal parts and converting it into current means dividing the current into several equal parts, each part considered as one unit. This can be seen as using the drive current corresponding to the minimum opening as a base point; each unit of current added upwards results in one opening, corresponding to one combustion intensity. The more parts the current is divided into, the smaller the adjustment range, and thus the smaller the temperature adjustment range.

[0106] Then, these combustion temperature ranges are smoothly connected from small to large to form a large continuous combustion temperature range. This corresponds to the oven's set temperature range, thus obtaining the aforementioned preset correlation information. Therefore, based on the set temperature, it can be determined which combustion temperature range the temperature should fall within. Once the combustion temperature range is determined, it is possible to determine which burner group to use, and which segment valves to control. Finally, the proportional valve opening is determined based on the temperature points within the combustion temperature range.

[0107] In this embodiment of the invention, a correlation between burner groups and corresponding set temperatures can be established in advance. Based on this correlation, a target burner that matches the set temperature indicated by the temperature control request can be queried, and then the valve opening value of the burner can be controlled to improve the response speed of temperature control and thus improve the user experience.

[0108] In summary, in this embodiment of the invention, upon detecting a temperature control request, the set temperature can be obtained, and the current temperature of the oven can be acquired in real time. Next, based on the current temperature and the set temperature, the current combustion stage of the oven can be determined. If the combustion stage is in the heating stage, all burners are controlled to ignite. Alternatively, if the combustion stage is not in the heating stage, a preset temperature is obtained, and based on the comparison between the set temperature and the preset temperature, the corresponding target burner is controlled to ignite. This achieves automated temperature control of the oven, improves the accuracy of heat adjustment, and consequently improves the efficiency of temperature regulation.

[0109] This embodiment also provides a temperature control device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function.
