[0045] 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.

[0046] In conjunction with the application scenarios on which the execution of the temperature control method depends, the application scenarios are described here.

[0047] In outdoor barbecue and other usage scenarios, the traditional outdoor gas grills mainly adjust the firepower manually, and the temperature adjustment mainly relies on the user's experience, or monitors the real-time temperature through a mechanical thermometer, and further adjusts the firepower according to the measured real-time temperature.

[0048] However, this manual operation method has a low level of intelligence, and the final temperature is highly uncertain. The inaccurate adjustment of the firepower makes the temperature uncontrollable, and there is no precise control of the temperature. At the same time, when rapid temperature adjustment is required, the efficiency of manual adjustment is often low and cannot meet the user's needs.

[0049] Based on this, an embodiment of the present invention provides a temperature control method for an oven. 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, the current combustion stage of the oven can be judged based on the current temperature and the set temperature. If the combustion stage is in the heating stage, all burners are controlled to burn. In addition, if the combustion stage is not in the heating stage, the preset temperature is obtained, and according to the comparison result between the set temperature and the preset temperature, the corresponding target burner is controlled to burn, thereby realizing the automation of the temperature control of the oven, improving the accuracy of the firepower adjustment, and thus improving the efficiency of the temperature adjustment.

[0050] According to an embodiment of the present invention, an embodiment of a temperature control method for an oven 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.

[0051] In this embodiment, a method for controlling the temperature of an oven is provided, which can be used for example Figure 2 The oven shown, Figure 1 is a flow chart of a temperature control method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0052] Step S101, after detecting a temperature control request, obtaining a set temperature, and obtaining the current temperature of the oven in real time.

[0053] In an embodiment of the present invention, the oven can be the above-mentioned gas oven, 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 section valve, a temperature sensor, and a burner.

[0054] Specifically, the display is used to display information such as the set temperature Ts, the real-time temperature Ta, and the status of the gas cylinder. Parameter setter: used to set the combustion temperature and other parameters of the gas oven. The burner is used to generate flames. Here, the gas oven can be provided with at least three burners with independent gas delivery channels. The main burner whose gas delivery channel is on and off controlled by a proportional valve is generally in the middle, such as burner 2. Other gas delivery channels are controlled by sectional valves, such as burner 1 and burner 3. The controller is used to receive the control instructions sent by the parameter setter, control the on and off of the proportional valve and the size of the proportional valve opening, so as to control the on and off and size of the total gas volume; to control the on and off of the sectional valve; during sectional combustion, the on and off of each sectional valve and the size of the proportional valve opening are controlled by an algorithm to adjust the size of the firepower in the furnace cavity, so as to achieve the effect of controlling the furnace cavity temperature to achieve a constant temperature.

[0055] In addition, the above-mentioned controller may also be integrated with an ignition device, a flame detection device and a temperature sensor. Specifically, the ignition device includes an ignition needle, which can be used to be installed at the gas outlet position of each burner, and is connected to the ignition device integrated in the controller through a high-voltage ignition line. The controller performs high-voltage discharge ignition when controlling ignition. The flame monitoring device includes a feedback needle, which is used to be installed at the gas outlet position of each burner, and is connected to the flame detection device integrated in the controller through a connecting line, and the flame signal is fed back to the main controller. The temperature sensor is used to detect the temperature in the furnace cavity, and the temperature signal in the furnace cavity is fed back to the controller. The controller sends a signal to control the opening size of the proportional valve and the combination of the sectional valve.

[0056] Specifically, Figure 2 The structure diagram of the gas oven is shown, where the gas oven includes three burners, burner 2 is the main burner, and burners 1 and 3 are auxiliary burners. Specifically, the main valve is used to connect to the main air inlet, and the output is connected to the input of the proportional valve through a pipeline, which is used to control the on and off of the gas in the main gas channel; the input end of the proportional valve is connected to the main gas channel, and the output is directly connected to the main burner 2, and is also connected to other segmented valve input ports, such as segmented valve 1 and segmented valve 3, to control the size of the total gas volume output and the size of the gas volume delivered to the main burner 2; the segmented valve is used to control the opening or closing state of the gas delivery channel of the burner, the input is connected to the proportional valve, and the output is directly connected to the auxiliary burners 1 and 3, and the number matches the number of corresponding devices, such as segmented valve 1 and segmented valve 2.

[0057] In the embodiment of the present 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 temperature rising stage, all burners are controlled to burn.

[0060] Step S104, if the combustion stage is not in the temperature rising stage, the preset temperature is obtained, and according to the comparison result between the set temperature and the preset temperature, the corresponding target burner is controlled to burn.

[0061] In an embodiment of the present 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. On the contrary, 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 it is determined that the combustion stage of the oven is the heating stage, all burners can be controlled to burn to speed up the heating rate. For example, all of the burners 1 to 3 are 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 according to the comparison result to control the target burner matching the target temperature range to burn.

[0064] For example, if the preset temperature is 230°C, when Ts is greater than 230°C, the target interval of the set temperature is determined to be the first temperature interval; when Ts is less than 230°C, the target interval of the set temperature is determined to be the second temperature interval. Considering that when the oven is in the non-heating stage, different target temperature intervals correspond to different firepower requirements, among which the first temperature interval has a high firepower requirement and the second temperature interval has a low firepower requirement. Here, the firepower can be controlled by controlling the number of target burners to be turned on, so as to achieve the purpose of temperature regulation. Specifically, if the target temperature interval is the first temperature interval, the target burner can be all burners, that is, burner 1-burner 3. In addition, if the target temperature interval is the second temperature interval, the target controller can be any single burner among burners 1-burner 3.

[0065] It can be seen from the above description that in an embodiment of the present invention, after a temperature control request is detected, the set temperature can be obtained, and the current temperature of the oven can be obtained in real time. Next, the current combustion stage of the oven can be determined based on the current temperature and the set temperature. If the combustion stage is in the heating stage, all burners are controlled to burn. In addition, if the combustion stage is not in the heating stage, the preset temperature is obtained, and the corresponding target burner is controlled to burn according to the comparison result between the set temperature and the preset temperature, thereby realizing the automation of the temperature control of the oven, improving the accuracy of the firepower adjustment, and thus improving the efficiency of the temperature adjustment.

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

[0067] Step S1041, if the set temperature is not less than the preset temperature, all burners are controlled to burn.

[0068] Step S1042: if the set temperature is lower than the preset temperature, some burners are controlled to burn.

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

[0070] Specifically, in the present invention, whether in the temperature reduction stage or the temperature control stage, 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 in burners 1 to 3 can be controlled to burn. In addition, when the set temperature Ts is not less than the preset temperature, all burners 1 to 3 need to 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, so as to ensure the temperature control effect and improve the temperature control accuracy.

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

[0073] Step S1011, determining a preset temperature based on the type of temperature control request.

[0074] Step S1012: if the temperature control request is a temperature increase request, the preset temperature is a first preset temperature.

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

[0076] In the embodiment of the present invention, the temperature increase request is used to indicate to increase the current set temperature Ts of the oven, and the temperature decrease request is used to decrease the current set temperature Ts of the oven. Here, considering that when the oven is in different temperature ranges, the firepower requirements are different when processing different temperature control requests, therefore, corresponding preset temperatures can be set in advance for different temperature control request types.

[0077] Specifically, the preset temperature corresponding to the temperature increase request can be set to the above-mentioned first preset temperature, and the preset temperature corresponding to the temperature decrease request can be set to the above-mentioned second preset temperature. As can be seen from the above, the first preset temperature should be greater than the second preset temperature, so as to avoid that when the set temperature Ts is repeatedly adjusted, all burners burn when the set temperature Ts is not less than the preset temperature, and only part of the burners burn when the set temperature TS is less than the preset temperature. If the set temperature Ts happens to be near the first preset temperature and the second preset temperature, it is easy to repeatedly ignite and extinguish the burners in the gas grill that are not burned when the set temperature TS is less than the preset temperature, resulting in frequent ignition sounds, affecting the user experience.

[0078] On this basis, it is further ensured that the difference between the first preset temperature and the second preset temperature is not less than 20°C, and it can be further ensured that the set temperature Ts is adjusted, and the burner that is not burning when the set temperature TS in the gas oven is less than the preset temperature will not be repeatedly ignited and extinguished. 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 temperature rise stage, a temperature drop stage and a constant temperature stage; in the above step S1041, if the set temperature is not less than the preset temperature, all burners are controlled to burn, including:

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

[0081] In addition, in step S1042, if the set temperature is lower than the preset temperature, controlling some burners to burn includes:

[0082] If the combustion stage is in the constant temperature stage, some burners are controlled to automatically adjust the power according to the current temperature and the set temperature. If the combustion stage is in the temperature reduction stage, some burners are controlled to burn at the first preset power.

[0083] In the embodiment of the present invention, the temperature rise stage may be a cold temperature rise stage, the temperature drop stage may be the above-mentioned hot temperature drop stage, and the constant temperature stage may be the above-mentioned temperature control stage. Here, when the combustion stage of the oven is in the constant temperature stage, the burner in the combustion state may be controlled to adaptively adjust the firepower to keep the current temperature Ta matching the set temperature Ts. Here, the proportional valve or sectional valve corresponding to each burner may be adjusted by automatic power adjustment to control the air intake, thereby adjusting the firepower.

[0084] Specifically, in the constant temperature stage, if the set temperature Ts is not less than the preset temperature, all burners (i.e., burner 1 to burner 3) can be controlled to automatically adjust the power according to the current temperature and the set temperature. In addition, if the set temperature Ts is less than the preset temperature, a single burner can be controlled to automatically adjust the power according to the current temperature and the set temperature, and other burners can be extinguished. For example, the main burner (i.e., the above-mentioned burner 2) can be controlled to automatically adjust the power, and burner 1 and burner 3 can be extinguished.

[0085] As can be seen from the above, the above preset temperature includes a first preset temperature and a second preset temperature, wherein, for the first preset temperature, when the burner is controlled to automatically adjust the power in the constant temperature stage, it is necessary to ensure that the difference between the current temperature Ta and the set temperature Ts is less than or equal to 10°C. In addition, for the second preset temperature, when the burner is controlled to automatically adjust the power in the constant temperature stage, it is necessary to ensure that the current temperature Ta reaches the set temperature Ts.

[0086] In addition, if the set temperature is not less 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 in the oven while maintaining the set temperature not less than the preset temperature.

[0087] In some optional embodiments, in the above step S103, if the combustion stage is in the temperature rising stage, all burners are controlled to burn, including:

[0088] If the combustion stage is in the temperature rising stage, all the burners are controlled to burn at a second preset power, wherein the second preset power is greater than the first preset power.

[0089] In the embodiment of the present invention, the second preset power can be used to control all burners to burn at a high fire, thereby increasing the heating speed in the heating stage.

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

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

[0092] Step S1022, 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 the cooling stage; when the current temperature reaches the set temperature, the current combustion stage of the oven is the constant temperature stage.

[0093] In the embodiment of the present invention, Figure 3 The flowchart of the temperature control method corresponding to the temperature increase request is shown, wherein the first temperature interval can be a set temperature Ts less than the above-mentioned first preset temperature, the second temperature interval can be a set temperature Ts greater than the above-mentioned first preset temperature, the first threshold value can be 10°C, and the second threshold value can be 50°C.

[0094] Specifically, it may first be determined whether the set temperature Ts-current temperature Ta≥50°C holds.

[0095] If not, the valve to be adjusted can be determined according to the temperature range where Ts is located to improve the temperature control accuracy. For example, when Ts is in the first temperature range, the required firepower is relatively small, so the proportional valve opening can be automatically adjusted to adjust only the firepower of burner 2. In addition, when Ts is in the second temperature range, the required firepower is relatively large, so the proportional valve and the sectional valve opening can be automatically adjusted to adjust the firepower of burners 1, 2 and 3.

[0096] If yes, the valve opening of the sectional valve and the proportional valve is opened to the maximum, and it is further determined whether Ts-Ta is less than 10°C. If yes, it is determined that the current combustion stage of the oven is the constant temperature stage, and the proportional valve opening is automatically adjusted to maintain a stable temperature. If no, it is determined that the current combustion stage of the oven is the constant temperature rise stage, and the valve opening of the sectional valve and the proportional valve is opened to the maximum to increase the temperature rise speed.

[0097] In the embodiment of the present invention, Figure 4 It is a flow chart of a temperature control method corresponding to a cooling request, wherein the third temperature interval can be a set temperature Ts less than a second preset temperature, and the fourth temperature interval can be a set temperature Ts greater than the second preset temperature.

[0098] Here, when Ts is in the third temperature interval, firstly, a single burner can be set to work at a low flame, and determine whether the current temperature Ta reaches Ts. If so, it is determined that the current combustion stage of the oven is a constant temperature stage, and the single burner is controlled to automatically adjust the power to automatically adjust the flame to maintain a stable temperature; if not, it is determined that the current combustion stage of the oven is a cooling stage, and the single burner is continued to be controlled to work at a low flame. In addition, when Ts is in the fourth temperature interval, firstly, all burners can be set to work at a low flame, and determine whether the current temperature Ta reaches Ts. If so, it is determined that the current combustion stage of the oven is a constant temperature stage, and all burners are controlled to automatically adjust the power to automatically adjust the flame to maintain a stable temperature; if not, it is determined that the current combustion stage of the oven is a cooling stage, and all burners are continued to be controlled to work at a low flame.

[0099] In some optional embodiments, the above Figure 1The corresponding implementations also include:

[0100] Step S11, determining a burner group matching the target temperature range based on preset association information, wherein the preset association information is used to indicate an association relationship between the burner group and the corresponding set temperature.

[0101] Step S12: determining a target burner that matches the temperature control request according to the burner group.

[0102] In the embodiment of the present invention, there are at least three oven burners, among which the proportional valve directly controls the on-off of the gas of one burner, which can be called the main burner, and the auxiliary burners each have an independent sectional valve directly controlling the on-off of the gas of the burner, so that the main burner and other burners can be arbitrarily combined to obtain a burner. Figure 2 Taking the gas grill in as an example, 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) can be obtained.

[0103] Each burner group will have a corresponding minimum and maximum firepower when the proportional valve opening is at the minimum and maximum, and the minimum and maximum firepower correspond to a minimum and maximum combustion temperature respectively, so that each combination corresponds to a combustion temperature range.

[0104] In the combustion temperature range corresponding to each combination, the proportional valve opening is divided into several equal parts between the minimum and maximum openings, and each part is regarded as a unit opening value. In this way, taking the minimum opening of the proportional valve as the base point, each time the opening is increased by one unit, there will be a combustion firepower, and a corresponding combustion temperature. Then, in this combustion temperature range, the combustion temperature can be controlled to be infinitely linearly adjusted between the minimum temperature and the maximum temperature of this section.

[0105] Here, the proportional valve opening is driven by current. One driving current corresponds to one proportional valve opening. Therefore, the way to convert the opening into current is to divide the current into several equal parts. Each equal part is regarded as one unit. Then, it can be regarded as taking the driving current corresponding to the minimum opening as the base point. Every time a unit of current is added, there will be an opening, which corresponds to a combustion power. The more parts the current is divided into, the smaller the adjustment range can be, and the smaller the temperature adjustment range is.

[0106] Then, these combustion temperature ranges are softly connected from small to large to form a large continuous combustion temperature range, which can be matched with the set temperature range of the oven to obtain the above preset association information. Therefore, according to the set temperature, it can be determined which combustion temperature range the temperature should be in. Once the combustion temperature range is determined, it can be determined which burner group to use, and it also knows which sectional valves to control. Finally, the proportional valve opening is determined according to the temperature point in the combustion temperature range.

[0107] In an embodiment of the present invention, an association relationship between a burner group and a corresponding set temperature can be established in advance, so that a target burner matching the set temperature indicated by the temperature control request can be queried based on the association relationship, and then the valve opening value of the burner can be controlled to increase the response speed of the temperature control, thereby improving the user experience.

[0108] In summary, in the embodiment of the present invention, after the temperature control request is detected, the set temperature can be obtained, and the current temperature of the oven can be obtained in real time. Next, the current combustion stage of the oven can be judged based on the current temperature and the set temperature. If the combustion stage is in the heating stage, all burners are controlled to burn. In addition, if the combustion stage is not in the heating stage, the preset temperature is obtained, and according to the comparison result between the set temperature and the preset temperature, the corresponding target burner is controlled to burn, thereby realizing the automation of the temperature control of the oven, improving the accuracy of the firepower adjustment, and thus improving the efficiency of the temperature adjustment.

[0109] In this embodiment, a temperature control device is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function.
