[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0047] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or server including a series of steps or units does not necessarily have to include only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product, or device.

[0048] Please refer to Figure 1 , Figure 1is a side view of an integrated cooker provided by an embodiment of the present application. The integrated cooker comprises a gas stove 1, an oil fume extractor 2 and a controller 3; the oil fume extractor 2 comprises a smoke cavity inlet 22 and a top plate 21, the top plate 21 is located above the smoke cavity inlet 22, and the smoke cavity inlet 22 is located at the side of the gas stove 1, one side of the top plate 21 facing the gas stove 1 is provided with an infrared temperature sensor 4, and the controller 3 is in communication connection with the oil fume extractor 2 and the infrared temperature sensor 4 respectively; optionally, the controller 3 can be arranged in a main machine 6 below the gas stove 1, and can also be arranged on the oil fume extractor 2 according to needs. Optionally, the oil fume extractor further comprises a smoke blocking area 5, and the smoke cavity inlet 22 is located above the smoke blocking area 5; when the oil fume extractor 2 is working, oil fume can be sucked into the smoke cavity from the smoke cavity inlet 22, so that the oil fume flows along the negative direction of the y-axis, and is finally discharged.

[0049] Optionally, the integrated cooker further comprises a touch function area, through which the functions of the integrated cooker can be controlled, such as starting or stopping the oil fume extractor 2, the air suction mode of the oil fume extractor 2, and the functions corresponding to other kitchen appliances (such as a disinfection cabinet, a steaming oven or a heat preservation box, etc.) integrated below the integrated cooker. Optionally, the touch function area can be located on the top of the oil fume extractor 2 or on the main machine 6.

[0050] At present, the contact type temperature sensor is arranged in the flue in the main machine and close to the area of the gas stove, although the temperature can be measured, but since it is located in the flue, it is easy to be affected by the external environment (such as the air suction amount), and there is a certain block between the gas stove, so the temperature measurement accuracy is low, and the reliability is poor. The present application collects the temperature by using the infrared temperature sensor, and arranges it on the top plate, so that the temperature measurement accuracy can be improved,

[0051] Please refer to Figure 2 , which shows a flowchart of a fire safety detection method for an integrated cooker provided by an embodiment of the present application. The method can be applied to the controller in Figure 1 . It should be noted that the present specification provides method operation steps as described in the embodiments or flowcharts, but more or fewer operation steps can be included based on conventional or non-creative labor. The order of steps listed in the embodiments is only one of the many execution orders, and does not represent the only execution order. In actual system or product execution, the method order shown in the embodiments or the drawings can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, as shown in Figure 2 , the method can comprise:

[0052] S201: Obtain the air suction mode of the oil fume extractor.

[0053] In the embodiment, the air extraction mode can include a low-speed air extraction mode and a high-speed air extraction mode, which are divided by motor speed. The low-speed air extraction mode corresponds to a speed of 600-900 r / min. The high-speed air extraction mode corresponds to a speed of 900 r / min or more. Of course, the air extraction mode can also be set to three gears, such as a low-speed air extraction mode, a medium-speed air extraction mode, and a high-speed air extraction mode. Correspondingly, the low-speed air extraction mode corresponds to a speed of 600-700 r / min. The medium-speed air extraction mode corresponds to a speed of 700-1000 r / min. The high-speed air extraction mode corresponds to a speed of 1000 r / min or more. There can also be other mode gears.

[0054] In the embodiment, the process of specifically obtaining the air extraction mode of the oil fume extraction device in step S201 can be, for example, that when the user selects the high gear by clicking the touch function area or other corresponding function button of the integrated cooker, the module controlling the oil fume extraction device sends the received air extraction mode information to the controller. The oil fume extraction device can also automatically select the air extraction mode according to the current oil fume condition and send the air extraction mode information to the controller, so that the controller obtains the air extraction mode of the oil fume extraction device.

[0055] To further improve the accuracy of the detection result of the present application, in a feasible embodiment, the method also considers the influence of the ambient temperature (such as the indoor temperature) on the detection result. The specific implementation can also include that the current ambient temperature can be obtained while step S201 is performed. The specific implementation of subsequent step S203 can be that the detection threshold is determined based on the current ambient temperature and the air extraction mode.

[0056] S203: Determine the detection threshold based on the air extraction mode.

[0057] In a feasible embodiment, the optional implementation of step S203 can be that a first detection threshold is determined when the air extraction mode is the low-speed air extraction mode, and a second detection threshold is determined when the air extraction mode is the high-speed air extraction mode. The second preset temperature in the second detection threshold is greater than the second preset temperature in the first detection threshold. By accurately and reasonably setting the detection threshold, the accuracy of the detection result is improved. Based on the above example, when the air extraction mode is divided into three or four gears, the corresponding detection threshold can be divided into three or four, of course, if the speed corresponding to the air extraction mode of the intermediate gear is relatively close to the speed corresponding to the lower gear or the upper gear, and does not greatly affect the accuracy of the detection temperature, the intermediate gear can also be classified as the threshold corresponding to the lower gear or the upper gear that is close to it. For example, when the air extraction mode includes a low-speed air extraction mode, a medium-speed air extraction mode, and a high-speed air extraction mode, and the speed corresponding to the medium-speed air extraction mode is relatively close to the speed corresponding to the low-speed air extraction mode, the threshold corresponding to the medium-speed air extraction mode can also be determined as the first detection threshold.

[0058] S205: Collecting the current temperature of the preset area above the gas stove by using the infrared temperature sensor.

[0059] The infrared temperature sensor is a non-contact temperature measuring device, mainly composed of an optical system, a control circuit and an output circuit. The optical system is used to receive the infrared radiation emitted by the object and focus it on the screen of the control circuit; the control circuit calculates the temperature of the object surface by processing the signals received by the optical system and outputs the results to the output circuit; the output circuit converts the calculated results into signals that can be read or stored by the user.

[0060] Referring to Figure 1 , by setting the infrared temperature sensor on the lower surface of the top plate and aligning it with the gas stove, the temperature of the corresponding area can be accurately and timely collected. Specifically, when the integrated stove has only one gas stove, it can have only one infrared temperature sensor, which can be set in the middle area of the top plate corresponding to the gas stove. When the integrated stove includes two gas stoves, the infrared temperature sensor can also be in the above layout, i.e., one infrared temperature sensor is set in the middle of the top plate. However, in order to more accurately detect the use safety of the gas stove, in another feasible embodiment, the integrated stove includes two infrared temperature sensors, each corresponding to an infrared temperature sensor above each gas stove. The specific implementation of the above step S205 can be: using two infrared temperature sensors to collect the current temperature of the corresponding preset area above the gas stove. Optionally, the top plate can be divided into left and right areas with the center line of the top plate as the dividing line, as shown in Figure 3 , specifically, one infrared temperature sensor can be set at the center position of the left area of the top plate, and another infrared temperature sensor can be set at the center position of the right area of the top plate. Then the detection results corresponding to each gas stove need to be determined respectively, and when the detection result corresponding to any one gas stove indicates that there is a fire safety risk, the operation of closing all functions of the integrated stove and the warning operation are performed. Specifically, the warning method can be voice prompt or long beep warning by using a buzzer. The specific long beep method of the buzzer can be 1 second of beeping every 2 seconds, which is not limited. That is, the specific implementation of the subsequent step S207 can include: determining the initial detection result based on the detection threshold and the current temperature for the current temperature collected by each infrared temperature sensor; the initial detection result represents the fire safety situation corresponding to one gas stove; determining the detection result based on the initial detection results corresponding to the two infrared temperature sensors. Optionally, when the detection result indicates that there is a fire safety risk, a fault code field can also be generated and stored locally or reported, so that the maintenance personnel can identify the fault type based on the fault code field.

[0061] For the case of higher requirements for detection accuracy, the specific implementation of step S205 can be: determining the larger one of the two current temperatures as the target current temperature; determining the detection result based on the target current temperature and the detection threshold.

[0062] S207: determining the detection result based on the detection threshold and the current temperature; the detection result represents the integrated stove fire safety situation.

[0063] In a feasible embodiment, the specific implementation of step S207 can include: in the case that the current temperature is less than the first preset temperature and greater than or equal to the second preset temperature, obtaining a first number of historical temperatures at consecutive historical moments; in the case that all the first number of historical temperatures are greater than or equal to a third preset temperature, generating a first detection result; the first detection result represents that the integrated stove has a fire safety risk; in the case that any one of the first number of historical temperatures is less than the third preset temperature, generating a second detection result; the second detection result represents that the integrated stove does not have a fire safety risk.

[0064] In another feasible embodiment, the specific implementation of step S207 can include: in the case that the current temperature is greater than or equal to the first preset temperature, obtaining a second number of historical temperatures at consecutive historical moments; in the case that all the second number of historical temperatures are greater than or equal to the first preset temperature, generating a first detection result. Optionally, the specific implementation of step S207 can also be described as: in the case that the current temperature is greater than or equal to the first preset temperature, obtaining a second number of historical temperatures at consecutive historical moments; in the case that any one of the second number of historical temperatures is less than the first preset temperature, obtaining a first number of historical temperatures at consecutive historical moments; the first number is greater than the second number; in the case that all the first number of historical temperatures are greater than or equal to a third preset temperature, generating a first detection result; the first detection result represents that the integrated stove has a fire safety risk; in the case that any one of the first number of historical temperatures is less than the third preset temperature, generating a second detection result; the second detection result represents that the integrated stove does not have a fire safety risk.

[0065] In the embodiment, the first preset temperature can be set to 65-75°C, for example, the first preset temperature can be 65°C, 67°C, 70°C, 72°C, or 75°C; the second preset temperature can be set to any temperature value between 40-50°C, for example, the second preset temperature can be 40°C, 42°C, 45°C, 47°C, or 50°C; the third preset temperature can be set to any temperature value between 15-25°C, for example, the third preset temperature can be 15°C, 20°C, 22°C, 24°C, or 25°C; when the infrared temperature sensor collects temperature every 1 second, the first number can be set to any number value in 5-15, and specifically, the first number can be set to 5, 7, 10, 12, or 15; that is, corresponding to 5-15 seconds; the second number can be set to any number value in 3-8, and specifically, the first number can be set to 3, 5, 6, 7, or 8; that is, corresponding to 3-8 seconds; of course, if the collection interval of the infrared temperature sensor is 0.5 seconds or 1.5 seconds, the first number will be adaptively increased or decreased, and the shorter the collection interval time, the more the first number and the second number, so in fact, the first number can be the number corresponding to the total sampling time of 5-15 seconds, and the second number can be the number corresponding to the total sampling time of 3-8 seconds. Thus, the detection result precision can be improved, the user's life and property safety can be more effectively ensured, and false triggering caused by the user stirring the food in a large fire can be avoided. In other words, when the current temperature satisfies any one of the following two preset conditions, it can be determined that the detection result is that there is a fire safety risk, preset condition 1: the current temperature is greater than or equal to the second preset temperature, and the temperature in the previous 5-15 seconds is greater than or equal to the third preset temperature; preset condition 2: the temperature in 3-8 seconds is greater than or equal to the first preset temperature.

[0066] It can be understood that, since the application considers the air draft mode and the ambient temperature, based on the above description, it can be understood that, the higher the motor speed corresponding to the air draft mode, that is, the greater the air draft, the larger the first preset temperature, the second preset temperature, and the third preset temperature shown in the example; the higher the ambient temperature, the larger the first preset temperature, the second preset temperature, and the third preset temperature.

[0067] In a feasible embodiment, the method further includes: controlling the working state of the related control module of the integrated cooker based on the detection result. Specifically, when the detection result represents that there is a fire safety risk, the functions of the integrated cooker and the warning operation are executed, and subsequently, when the current temperature collected by the infrared temperature sensor is less than or equal to a fourth preset temperature, the buzzing of the buzzer is stopped; optionally, the fourth preset temperature can be equal to the third preset temperature, such as 70°C; or it can be set to other suitable temperature values, which are not limited herein.

[0068] According to the technical solutions of the embodiments of the present application, the smoke extraction mode of the oil fume extraction device is acquired, the detection threshold is determined based on the smoke extraction mode, the current temperature of a preset area above the gas stove is collected by using the infrared temperature sensor, the detection result is determined based on the detection threshold and the current temperature, and the detection result represents the fire safety condition of the integrated stove, so that the fire safety condition can be more accurately judged, the personal and property losses of the user can be avoided, the integrated kitchen is safer and more secure, and the user experience is improved.
