[0032] The present invention provides a control method and a control device for an air fryer.

[0033] A chassis, a first electric heating device, a second electric heating device, a first fan and a second fan are arranged in the air fryer. The first electric heating device and the first fan are arranged above a first area of the chassis. The first fan drives the hot air heated by the first heater to the first area of the chassis to heat the food in the first area. The second electric heating device and the second fan are arranged above a second area of the chassis. The second fan drives the hot air heated by the second heater to the second area of the chassis to heat the food in the second area.

[0034] In a specific embodiment, the first fan is arranged above the first electric heating device, and the rotation axis of the first fan extends in the vertical direction. The first fan drives the hot air heated by the first heater to the first area of the chassis below the first heater. The second fan is arranged above the second electric heating device, and the rotation axis of the second fan extends in the vertical direction.

[0035] In another specific embodiment, a first air duct is provided between the first blower and the first area of the chassis, and a second air duct is provided between the second blower and the second area of the chassis. A first electric heater and a second electric heater are respectively provided in the first air duct and the second air duct. The first electric heater is disposed on the inner wall of the first air duct and / or at the air inlet and / or the air outlet of the first air duct. The first blower drives the hot air heated by the first heater in the first air duct to the first area of the chassis. The second electric heater is disposed on the inner wall of the second air duct and / or at the air inlet and / or the air outlet of the second air duct. The second blower drives the hot air heated by the second heater in the second air duct to the first area of the chassis.

[0036] Figure 2a Fig. 4 shows a side structural view of an air fryer according to a specific embodiment of the present invention. Figure 2b Fig. 5 shows a top structural view of an air fryer according to a specific embodiment of the present invention. As Figure 2a 、 Figure 2b shown, in a specific embodiment, the first blower 11 is horizontally disposed, that is, the rotation axis of the first blower 11 extends in the horizontal direction. A first air duct 31 is provided between the (air outlet of the) first blower 11 and the first area of the chassis 4. The air inlet of the first air duct 31 faces the (air outlet of the) first blower 11 and gradually extends downward smoothly in the horizontal direction to the vertical direction, which can reduce the occupied space and the volume inside the air fryer. The first blower 11 drives the hot air heated by the first heater 21 in the first air duct 31 to the first area of the chassis 4. The second blower 12 is horizontally disposed, that is, the rotation axis of the second blower 12 extends in the horizontal direction. A second air duct 32 is provided between the (air outlet of the) second blower 12 and the second area of the chassis 4. The air inlet of the second air duct 32 faces the (air outlet of the) second blower 12 and gradually extends downward smoothly in the horizontal direction to the vertical direction, which can reduce the occupied space and the volume inside the air fryer. The second blower 12 drives the hot air heated by the first heater 22 in the second air duct 32 to the first area of the chassis 4. The first electric heater 21 is disposed on the inner wall, air inlet and air outlet of the first air duct 31; the second electric heater 22 is disposed on the inner wall, air inlet and air outlet of the second air duct 32. In a specific embodiment, the first electric heater and the second electric heater may be PTC electric heaters. The first blower 11 and the first air duct 31 and the second blower 12 and the second air duct 32 may be rotationally symmetrically disposed, which can also reduce the occupied space and the volume inside the air fryer.

[0037] In another specific embodiment, the rotation axis of the first blower extends in the vertical direction, and a first air duct is provided below the first blower. The first blower drives the hot air heated by the first heater to the first area of the chassis below the first heater; the rotation axis of the second blower extends in the vertical direction, and a second air duct is provided below the second blower. The second blower drives the hot air heated by the second heater to the first area of the chassis below the second heater. The first electric heater is disposed on the inner wall of the first air duct and / or at the air inlet and / or air outlet of the first air duct, and the second electric heater is disposed on the inner wall of the second air duct and / or at the air inlet and / or air outlet of the second air duct.

[0038] The first area and the second area are divided by a straight line passing through the center of the chassis. For example, taking the straight line passing through the center of the chassis as the dividing line, the chassis is divided into two left and right areas or two front and rear areas. Above the two left and right areas or two front and rear areas, a first electric heating device and a first blower, as well as a second electric heating device and a second blower are respectively provided.

[0039] The chassis is provided with a pressure detection device for detecting whether the position of the food placed on the chassis biases towards the first area or the second area of the chassis. Refer to Figure 2a As shown, the pressure detection device 5 can be disposed at the center of the chassis 4. The pressure detection device 5 can be disposed below the chassis 4, in contact with the chassis, and determines the food position through the pressure change brought by the food to the chassis. The pressure detection device can specifically be a pressure sensor, and determines whether the position of the food placed on the chassis biases towards the first area or the second area of the chassis by detecting the pressure magnitude. For example, the pressure detection device can specifically be a weighing scale, disposed at the center of the chassis, and capable of detecting whether the position of the food placed on the chassis biases towards the first area or the second area of the chassis. For example, taking the front of the air fryer as the front and the back as the rear, the weighing scale is disposed along the front and back direction of the air fryer to detect whether the position of the food placed on the chassis biases towards the front side area or the rear side area of the chassis, or the weighing scale is disposed along the left and right direction of the air fryer to detect whether the position of the food placed on the chassis biases towards the left side area or the right side area of the chassis.

[0040] Figure 1 is a schematic diagram of a method of an embodiment of the control method of the air fryer provided by the present invention.

[0041] As Figure 1 shown, according to an embodiment of the present invention, the control method at least includes step S110, step S120, and step S130.

[0042] Step S110: Detect whether the position of the food placed on the chassis is biased towards the first area or the second area of the chassis through the pressure detection device.

[0043] Specifically, when the absolute value of the difference between the weight of the first area and the weight of the second area is greater than or equal to a preset threshold, if the weight of the first area is greater than the weight of the second area, it is determined that the position of the food placed on the chassis is biased towards the first area; if the weight of the first area is less than the weight of the second area, it is determined that the position of the food placed on the chassis is biased towards the second area. When the absolute value of the difference between the weight of the first area and the weight of the second area is less than the preset threshold, it is determined that the position of the food placed on the chassis is not biased towards any of the first area and the second area.

[0044] Step S120: If it is detected that the position of the food placed on the chassis is biased towards the first area or the second area of the chassis, control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to a preset differential heating program.

[0045] In a specific embodiment, if it is detected that the position of the food is biased towards the first area of the chassis, control the first blower to operate at the first preset multiple of the set time and / or control the first electric heating device to operate at the first preset multiple of the set time and / or at the third preset multiple of the set temperature; control the second blower to operate at the second preset multiple of the set time and / or control the second electric heating device to operate at the second preset multiple of the set time and / or at the fourth preset multiple of the set temperature.

[0046] If it is detected that the position of the food is biased towards the second area of the chassis, control the first blower to operate at the second preset multiple of the set time and / or control the first electric heating device to operate at the second preset multiple of the set time and / or at the fourth preset multiple of the set temperature; control the second blower to operate at the first preset multiple of the set time and / or control the second electric heating device to operate at the first preset multiple of the set time and / or at the third preset multiple of the set temperature.

[0047] The first preset multiple is less than or equal to 1, and the first preset multiple is greater than the second preset multiple; the third preset multiple is less than or equal to 1, and the third preset multiple is greater than the fourth preset multiple.

[0048] In a specific embodiment, the set temperature and / or the set time are determined according to the food type, and different food types correspond to different heating programs. That is, different food types correspond to different set heating programs and / or differential heating programs.

[0049] Specifically, if the position of the food placed on the chassis is biased towards the first area of the chassis (for example, the food position is biased towards the left side of the chassis), then control the first blower to continuously operate for a time that is the first preset multiple of the set time, and / or control the first electric heating device to operate at the third preset multiple of the set temperature for a time that is the first preset multiple of the set time; wherein, when it is detected that the temperature (in the first area) reaches the third preset multiple of the set temperature, control the electric heating device to stop working, and when it is detected that the temperature (in the first area) drops to the fifth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is the first preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is the third preset multiple of the set temperature). Control the second blower to continuously operate for a time that is the second preset multiple of the set time, and / or control the second electric heating device to operate at the fourth preset multiple of the set temperature for a time that is the second preset multiple of the set time; wherein, when it is detected that the temperature (in the first area) reaches the fourth preset multiple of the set temperature, control the electric heating device to stop working, and when it is detected that the temperature (in the second area) drops to the sixth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is the second preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is the fourth preset multiple of the set temperature).

[0050] If the position of the food placed on the chassis is biased towards the second area of the chassis (for example, the food position is biased towards the right side of the chassis), then control the first blower to continuously operate for a time that is the second preset multiple of the set time, and / or control the first electric heating device to operate at the fourth preset multiple of the set temperature for a time that is the second preset multiple of the set time; wherein, when it is detected that the temperature (in the second area) reaches the fourth preset multiple of the set temperature, control the electric heating device to stop working, and when it is detected that the temperature (in the second area) drops to the sixth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is the second preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is the fourth preset multiple of the set temperature).

[0051] Control the second blower to continuously operate within a time that is a first preset multiple of the set time, and / or control the second electric heating device to operate at a third preset multiple of the set temperature within a time that is a first preset multiple of the set time. Wherein, when it is detected that the temperature (in the second area) reaches a third preset multiple of the set temperature, control the electric heating device to stop working; when it is detected that the temperature (in the second area) drops to a fifth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is a first preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is a third preset multiple of the set temperature).

[0052] For example, the first preset multiple is 100%, the second preset multiple is 70%, the third preset multiple is 100%, and the fourth preset multiple is 70%. If it is detected that the position of the food placed on the chassis is biased towards the left side of the chassis, the first blower (left blower) operates for 100% of the set time, and the first electric heating device (left electric heating device) operates for 100% of the set time and at 100% of the set temperature. That is, the first blower continuously operates for 100% of the set time, and the first electric heating device operates at 100% of the set temperature within 100% of the set time. For example, when it is detected that the temperature (in the first area) reaches 100% of the set temperature, the first electric heating device stops working. At this time, the residual heat of the first electric heating device will cause the temperature to continue to rise slightly. When it is detected that the temperature (in the first area) drops to a fifth preset multiple of the set temperature (the fifth preset multiple is less than the third preset multiple, for example, 95%), the first electric heating device starts working, that is, the temperature is controlled within a certain range of the set temperature within 100% of the set time. And the second blower (right blower) operates for 70% of the set time, and the second electric heating device (right electric heating device) operates for 70% of the set time and at 70% of the set temperature. That is, the second blower continuously operates for 70% of the set time, and the second electric heating device operates at 70% of the set temperature within 70% of the set time. For example, when it is detected that the temperature (in the second area) reaches 70% of the set temperature, the second electric heating device stops working. At this time, the residual heat of the second electric heating device will cause the temperature to continue to rise slightly. When it is detected that the temperature (in the second area) drops to a sixth preset multiple of the set temperature (the sixth preset multiple is less than the fourth preset multiple, for example, 65%), the second electric heating device starts working, that is, the temperature is controlled within a certain range of the set temperature within 70% of the set time.

[0053] If it is detected that the position of the food placed on the chassis is biased towards the right side of the chassis, the second blower (right blower) operates according to 100% of the set time, and the second electric heating device (right electric heating device) operates according to 100% of the set time and 100% of the set temperature. That is, the second blower continuously operates for 100% of the set time, and the second electric heating device operates at 100% of the set temperature within 100% of the set time. For example, when it is detected that the temperature (in the second area) reaches 100% of the set temperature, the second electric heating device stops working. At this time, the residual heat of the second electric heating device will cause the temperature to rise slightly (for example, it can rise by 5%). When it is detected that the temperature (in the second area) drops to the fifth preset multiple of the set temperature (the fifth preset multiple is less than the third preset multiple, for example, 95%), the second electric heating device starts to work, that is, the temperature is controlled within a certain range of the set temperature within 100% of the set time. And the first blower (left blower) operates according to 70% of the set time, and the first electric heating device (left electric heating device) operates according to 70% of the set time and 70% of the set temperature. That is, the first blower continuously operates for 70% of the set time, and the first electric heating device operates at 70% of the set temperature within 100% of the set time. For example, when it is detected that the temperature (in the first area) reaches 70% of the set temperature, the first electric heating device stops working. At this time, the residual heat of the first electric heating device will cause the temperature to rise slightly. When it is detected that the temperature (in the first area) drops to the sixth preset multiple of the set temperature (the sixth preset multiple is less than the fourth preset multiple, for example, 65%), the first electric heating device starts to work, that is, the temperature is controlled within a certain range of the set temperature within 70% of the set time.

[0054] Step S130, if it is detected that the position of the food placed on the chassis does not bias towards any one of the first area and the second area of the chassis, then control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to the set heating program.

[0055] Specifically, if it is detected that the position of the food placed on the chassis does not bias towards any one of the first area and the second area of the chassis, that is, the position of the food placed on the chassis is centered, then control the first blower and the second blower to operate according to the set time, and / or control the first electric heating device and the second electric heating device to operate according to the set time and / or according to the set temperature.

[0056] For example, if it is detected that the position of the food placed in the chassis is centered, the first blower (left blower) and the second blower (right blower) operate for 100% of the set time, and the first electric heating device (left electric heating device) and the second electric heating device (right electric heating device) operate for 100% of the set time and at 100% of the set temperature. That is, the first blower and the second blower continuously operate for 100% of the set time, and the first electric heating device and the second electric heating device operate at 100% of the set temperature within 100% of the set time. For example, when it is detected that the temperature in the (first area and / or second area) reaches 100% of the set temperature, the first electric heating device and / or the second electric heating device stops working. At this time, the residual heat of the first electric heating device and / or the second electric heating device will cause the temperature to continue to rise slightly. When it is detected that the temperature in the (first area and / or second area) drops to the fifth preset multiple of the set temperature (the fifth preset multiple is less than the third preset multiple, for example, 95%), the first electric heating device and / or the second electric heating device restarts working, that is, the temperature is controlled within a certain range of the set temperature within 100% of the set time.

[0057] According to the above embodiments of the present invention, by the pressure brought by the food at different positions to the chassis, it is judged which area of the air fryer the food is close to, and then different heating programs are executed, avoiding rapid overheating caused by single-sided concentrated heating of a single food, resulting in carbonization of the food and making it inedible. By different heating directions for different food positions, it is avoided that the food is overheated and carbonized due to concentrated heating on one side caused by position differences.

[0058] Figure 3 It is a schematic diagram of a method of another embodiment of the control method of the air fryer provided by the present invention. According to another embodiment of the present invention, a carbonization induction device is provided in the air fryer. The carbonization induction device can be arranged, for example, at the air outlet of the air fryer.

[0059] As Figure 3 shown, according to an embodiment of the present invention, the control method further includes step S140 and step S150.

[0060] Step S140, when the air fryer is working, detect whether the carbon content in the gas in the air fryer is higher than a preset threshold through the carbonization induction device.

[0061] Step S150, if it is detected that the carbon content in the gas in the air fryer is higher than the preset threshold, control the air fryer to stop working and issue an alarm.

[0062] The carbonization induction device can specifically be a carbonization inductor. In a specific embodiment, the carbonization induction device is arranged at the air outlet of the air fryer. For example, one carbonization induction device can be arranged at each of the first air outlet and the second air outlet of the air fryer. The overburning alarm is realized by detecting the passing frequency of carbon atoms in the air passing through the carbonization induction device. For example, when the gas passes through the carbonization inductor, the inductor emits red light. The carbon in the passing gas will absorb the energy of a specific wavelength, and the remaining energy in the specific wavelength is measured. The amount of light absorbed is proportional to the amount of carbon dioxide present in the air flow. Therefore, the carbon content in the gas can be accurately measured. When the carbon content in the passing gas is higher than a preset threshold (such as 1000 ppm), the inductor is triggered to alarm, the air fryer stops working, and the user is reminded through a buzzer.

[0063] According to the above embodiments of the present invention, by setting a carbonization induction device to test the carbon content in the gas inside the air fryer, so as to judge whether there is a risk of overheating carbonization in the air fryer, the reliability of the heating program of the air fryer can be improved, food burning can be avoided, the working achievement rate of the air fryer can be increased, and the user experience can be improved.

[0064] Optionally, the air fryer includes: a programmable logic controller PLC; the operation of the first electric heating device, the first blower, the second electric heating device and the second blower is controlled by the programmable logic controller.

[0065] Specifically, the programmable logic controller PLC is provided with a temperature measurement module for collecting the temperature inside the chassis; the temperature measurement module collects the temperature signals detected by the temperature measurement elements inside the air fryer, so as to control the first electric heating device, the first blower, the second electric heating device and the second blower to operate according to the set heating program, or control the first electric heating device, the first blower, the second electric heating device and the second blower to operate according to a preset differentiated heating program.

[0066] For example, a temperature measurement module is added at the reserved position of the PLC system to collect the temperature signals of the temperature measurement elements; then, the problem of temperature control logic needs to be considered, so the PLC program is modified, and a program segment about temperature control logic is added. The temperature measurement module collects the temperature signals of the temperature measurement elements and sends them to the CPU for processing, and then controls the start and stop of the electric heater according to the newly added temperature control logic in the PLC program. When the temperature rises to the set temperature, the power of the electric heater is reduced to maintain the temperature within the set temperature range. By setting the expression of the temperature measurement module in the PLC, the temperature data collected by the temperature measurement module is assigned to the PLC variable, and the variable is compared in the expression of the comparison block to output the state, thereby realizing the temperature control logic, and controlling the heating rate by comparing the change of the temperature threshold.

[0067] In order to clearly illustrate the technical solution of the present invention, the execution process of the control method of the air fryer provided by the present invention is described below with a specific embodiment.

[0068] Figure 4 FIG. 1 is a schematic diagram of a specific embodiment of the control method of the air fryer provided by the present invention. Figure 4 As shown,

[0069] After the user puts the food in, the air fryer starts and determines whether the food is on the left, right, or in the center. When the food is determined to be biased, if the food is on the left (towards the left area of ​​the chassis), the left fan and the left electric heater will execute 100% of the set time and 100% of the set temperature, and the right fan and the right electric heater will execute 70% of the set time and 70% of the set temperature. If the food is in the center, the left and right fans and the left and right electric heaters will all execute 100% of the set time and 100% of the set temperature. If the food is on the right (towards the right area of ​​the chassis), the left fan and the left electric heater will execute 70% of the set time and 70% of the set temperature, and the right fan and the right electric heater will execute 100% of the set time and 100% of the set temperature. The left and right fans and the left and right electric heaters work, the temperature continues to rise, the temperature measuring element continues to work, and when the target temperature is reached, the corresponding left electric heater or right electric heater stops working, and the residual heat causes the temperature to continue to rise, and then the temperature drops. After it drops to a certain temperature, the corresponding left electric heater or right electric heater starts working, and the above process is repeated to control the temperature within a certain range of the target temperature until the set time is reached, the heating ends, and the user takes out the food. When the food is overburned and carbonized, the carbonization sensor sends a signal, the air fryer stops working and sounds an alarm to alert the user.

[0070] Figure 5 FIG. 1 is a structural block diagram of an embodiment of the control device of the air fryer provided by the present invention. Figure 5 As shown, the control device 100 includes: a first detection unit 110 and a first control unit 120 .

[0071] The first detection unit 110 is used to detect whether the position of the food put into the bottom plate is biased towards the first area or the second area of ​​the bottom plate through the pressure detection device.

[0072] Specifically, when the absolute value of the difference between the weight of the first region and the weight of the second region is greater than or equal to a preset threshold, if the weight of the first region is greater than the weight of the second region, it is determined that the position of the food placed on the chassis is biased towards the first region; if the weight of the first region is less than the weight of the second region, it is determined that the position of the food placed on the chassis is biased towards the second region. When the absolute value of the difference between the weight of the first region and the weight of the second region is less than the preset threshold, it is determined that the position of the food placed on the chassis is not biased towards either the first region or the second region.

[0073] The first control unit 120 is configured to, if the first detection unit 110 detects that the position of the food placed on the chassis is biased towards the first region or the second region of the chassis, control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to a preset differential heating program; if the first detection unit 110 detects that the position of the food placed on the chassis is not biased towards either the first region or the second region of the chassis, control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to a set heating program.

[0074] In a specific embodiment, if it is detected that the position of the food is biased towards the first region of the chassis, control the first blower to operate at a first preset multiple of the set time and / or control the first electric heating device to operate at a first preset multiple of the set time and / or at a third preset multiple of the set temperature; control the second blower to operate at a second preset multiple of the set time and / or control the second electric heating device to operate at a second preset multiple of the set time and / or at a fourth preset multiple of the set temperature.

[0075] If it is detected that the position of the food is biased towards the second region of the chassis, control the first blower to operate at a second preset multiple of the set time and / or control the first electric heating device to operate at a second preset multiple of the set time and / or at a fourth preset multiple of the set temperature; control the second blower to operate at a first preset multiple of the set time and / or control the second electric heating device to operate at a first preset multiple of the set time and / or at a third preset multiple of the set temperature.

[0076] The first preset multiple is less than or equal to 1, and the first preset multiple is greater than the second preset multiple; the third preset multiple is less than or equal to 1, and the third preset multiple is greater than the fourth preset multiple.

[0077] In a specific embodiment, the set temperature and / or the set time are determined according to the type of food, and different food types correspond to different heating programs. That is, different food types correspond to different set heating programs and / or differentiated heating programs.

[0078] Specifically, if it is detected that the position of the food placed on the chassis is biased towards the first area of the chassis (for example, the food position is biased towards the left side of the chassis), then control the first blower to continuously operate for a time that is the first preset multiple of the set time, and / or control the first electric heating device to operate at the third preset multiple of the set temperature for a time that is the first preset multiple of the set time; wherein, when it is detected that the temperature (in the first area) reaches the third preset multiple of the set temperature, control the electric heating device to stop working, and when it is detected that the temperature (in the first area) drops to the fifth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is the first preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is the third preset multiple of the set temperature). Control the second blower to continuously operate for a time that is the second preset multiple of the set time, and / or control the second electric heating device to operate at the fourth preset multiple of the set temperature for a time that is the second preset multiple of the set time; wherein, when it is detected that the temperature (in the first area) reaches the fourth preset multiple of the set temperature, control the electric heating device to stop working, and when it is detected that the temperature (in the second area) drops to the sixth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is the second preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is the fourth preset multiple of the set temperature).

[0079] If it is detected that the position of the food placed on the chassis is biased towards the second area of the chassis (for example, the food position is biased towards the right side of the chassis), then control the first blower to continuously operate for a time that is the second preset multiple of the set time, and / or control the first electric heating device to operate at the fourth preset multiple of the set temperature for a time that is the second preset multiple of the set time; wherein, when it is detected that the temperature (in the second area) reaches the fourth preset multiple of the set temperature, control the electric heating device to stop working, and when it is detected that the temperature (in the second area) drops to the sixth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is the second preset multiple of the set time), repeatedly execute the above process to control the temperature within a certain range of the target temperature (here it is the fourth preset multiple of the set temperature).

[0080] Control the second fan to continuously operate within a time that is a first preset multiple of the set time, and / or control the second electric heating device to operate at a third preset multiple of the set temperature within a time that is a first preset multiple of the set time. Wherein, when it is detected that the temperature (in the second area) reaches a third preset multiple of the set temperature, control the electric heating device to stop working; when it is detected that the temperature (in the second area) drops to a fifth preset multiple of the set temperature, control the electric heating device to start working. That is, within the target heating time (here it is a first preset multiple of the set time), the above process is repeatedly executed to control the temperature within a certain range of the target temperature (here it is a third preset multiple of the set temperature).

[0081] For example, the first preset multiple is 100%, the second preset multiple is 70%, the third preset multiple is 100%, and the fourth preset multiple is 70%. If it is detected that the position of the food placed on the chassis is biased towards the left side of the chassis, the first fan (left fan) operates for 100% of the set time, and the first electric heating device (left electric heating device) operates for 100% of the set time and at 100% of the set temperature. That is, the first fan continuously operates for 100% of the set time, and the first electric heating device operates at 100% of the set temperature within 100% of the set time. For example, when it is detected that the temperature (in the first area) reaches 100% of the set temperature, the first electric heating device stops working. At this time, the residual heat of the first electric heating device will cause the temperature to continue to rise slightly. When it is detected that the temperature (in the first area) drops to a fifth preset multiple of the set temperature (the fifth preset multiple is less than the third preset multiple, for example, 95%), the first electric heating device starts working, that is, the temperature is controlled within a certain range of the set temperature within 100% of the set time. And the second fan (right fan) operates for 70% of the set time, and the second electric heating device (right electric heating device) operates for 70% of the set time and at 70% of the set temperature. That is, the second fan continuously operates for 70% of the set time, and the second electric heating device operates at 70% of the set temperature within 70% of the set time. For example, when it is detected that the temperature (in the second area) reaches 70% of the set temperature, the second electric heating device stops working. At this time, the residual heat of the second electric heating device will cause the temperature to continue to rise slightly. When it is detected that the temperature (in the second area) drops to a sixth preset multiple of the set temperature (the sixth preset multiple is less than the fourth preset multiple, for example, 65%), the second electric heating device starts working, that is, the temperature is controlled within a certain range of the set temperature within 70% of the set time.

[0082] If it is detected that the position of the food placed in the chassis is biased towards the right side of the chassis, then the second blower (right blower) operates according to 100% of the set time, and the second electric heating device (right electric heating device) operates according to 100% of the set time and 100% of the set temperature. That is, the second blower continuously operates for 100% of the set time, and the second electric heating device operates at 100% of the set temperature within 100% of the set time. For example, when it is detected that the temperature (in the second area) reaches 100% of the set temperature, the second electric heating device stops working. At this time, the residual heat of the second electric heating device will cause the temperature to rise a little further (for example, it can rise by 5%). When it is detected that the temperature (in the second area) drops to the fifth preset multiple of the set temperature (the fifth preset multiple is less than the third preset multiple, for example, 95%), the second electric heating device starts to work, that is, the temperature is controlled within a certain range of the set temperature within 100% of the set time. And the first blower (left blower) operates according to 70% of the set time, and the first electric heating device (left electric heating device) operates according to 70% of the set time and 70% of the set temperature. That is, the first blower continuously operates for 70% of the set time, and the first electric heating device operates at 70% of the set temperature within 100% of the set time. For example, when it is detected that the temperature (in the first area) reaches 70% of the set temperature, the first electric heating device stops working. At this time, the residual heat of the first electric heating device will cause the temperature to rise a little further. When it is detected that the temperature (in the first area) drops to the sixth preset multiple of the set temperature (the sixth preset multiple is less than the fourth preset multiple, for example, 65%), the first electric heating device starts to work, that is, the temperature is controlled within a certain range of the set temperature within 70% of the set time.

[0083] If it is detected that the position of the food placed in the chassis is not biased towards any of the first area and the second area of the chassis, that is, the position of the food placed in the chassis is centered, then control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to the set heating program. Specifically, if the position of the food placed in the chassis is centered, then control the first blower and the second blower to operate according to the set time, and / or control the first electric heating device and the second electric heating device to operate according to the set time and / or according to the set temperature.

[0084] For example, if the position of the food placed in the chassis is centered, the first blower (left blower) and the second blower (right blower) operate for 100% of the set time, and the first electric heating device (left electric heating device) and the second electric heating device (right electric heating device) operate at 100% of the set time and 100% of the set temperature. That is, the first blower and the second blower continuously operate for 100% of the set time, and the first electric heating device and the second electric heating device operate at 100% of the set temperature within 100% of the set time. For example, when it is detected that the temperature in the (first area and / or second area) reaches 100% of the set temperature, the first electric heating device and / or the second electric heating device stops working. At this time, the residual heat of the first electric heating device and / or the second electric heating device will cause the temperature to continue to rise slightly. When it is detected that the temperature in the (first area and / or second area) drops to the fifth preset multiple of the set temperature (the fifth preset multiple is less than the third preset multiple, for example, 95%), the first electric heating device and / or the second electric heating device restarts to work, that is, the temperature is controlled within a certain range of the set temperature within 100% of the set time.

[0085] According to the above embodiments of the present invention, by the pressure brought by the food at different positions to the chassis, it is judged which area of the air fryer the food is close to, and then different heating programs are executed, avoiding rapid overheating caused by single-sided concentrated heating of a single food, resulting in carbonization of the food and making it inedible. By different heating directions for different food positions, it is avoided that the food is overheated and carbonized due to concentrated heating on one side caused by position differences.

[0086] Figure 6 It is a structural block diagram of another embodiment of the control device of the air fryer provided by the present invention. According to another embodiment of the present invention, a carbonization induction device is provided in the air fryer. The carbonization induction device can be set, for example, at the air outlet of the air fryer.

[0087] As Figure 6 shown, the control device 100 further includes: a second detection unit 130 and a second control unit 140.

[0088] The second detection unit 130 is used to detect whether the carbon content in the gas in the air fryer is higher than a preset threshold through the carbonization induction device when the air fryer is working. The second control unit 140 is used to control the air fryer to stop working and issue an alarm if the second detection unit 130 detects that the carbon content in the gas in the air fryer is higher than the preset threshold.

[0089] The carbonization induction device can specifically be a carbonization inductor. In a specific embodiment, the carbonization induction device is arranged at the air outlet of the air fryer. For example, one carbonization induction device can be arranged at each of the first air outlet and the second air outlet of the air fryer. The overburning alarm is realized by detecting the passing frequency of carbon atoms in the air passing through the carbonization induction device. For example, when the gas passes through the carbonization inductor, the inductor emits red light. The carbon in the passing gas will absorb the energy of a specific wavelength. Measure the remaining energy in the specific wavelength. The amount of light absorbed is proportional to the amount of carbon dioxide present in the air flow. Therefore, the carbon content in the gas can be accurately measured. When the carbon content in the passing gas is higher than a preset threshold (for example, 1000 ppm), the inductor is triggered to alarm, the air fryer stops working, and the user is reminded through a buzzer.

[0090] According to the above embodiments of the present invention, by setting a carbonization induction device to test the carbon content in the gas inside the air fryer, thereby judging whether there is a risk of overheating and carbonization in the air fryer, the reliability of the heating program of the air fryer can be improved, food burning can be avoided, the working achievement rate of the air fryer can be increased, and the user experience can be improved.

[0091] Optionally, the air fryer includes: a programmable logic controller; the operation of the first electric heating device, the first blower, the second electric heating device, and the second blower is controlled by the programmable logic controller.

[0092] Specifically, the programmable logic controller PLC is provided with a temperature measurement module for collecting the temperature inside the chassis; the temperature measurement module collects the temperature signal detected by the temperature measurement element inside the air fryer, so as to control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to the set heating program, or control the first electric heating device, the first blower, the second electric heating device, and the second blower to operate according to a preset differentiated heating program. The present invention also provides a storage medium corresponding to the control method of the air fryer, on which a computer program is stored, and when the program is executed by a processor, the steps of any of the foregoing methods are implemented.

[0093] The present invention also provides an air fryer corresponding to the control method of the air fryer, including a processor, a memory, and a computer program stored on the memory and operable on the processor. When the processor executes the program, the steps of any of the foregoing methods are implemented.

[0094] The present invention also provides an air fryer corresponding to the control device of the air fryer, including the control device of any of the foregoing air fryers.

[0095] The present invention also provides a computer program product corresponding to the control method of the air fryer, including a computer program, and when the computer program is executed by a processor, the steps of any of the foregoing methods are implemented.

[0096] Accordingly, the solution provided by the present invention determines which area of the air fryer the food is close to by the pressure brought by the food at different positions to the chassis, and then executes different heating programs, avoiding rapid overheating caused by single-sided concentrated heating of the food, resulting in the food being carbonized and inedible. By differentiating the heating directions according to different food positions, it avoids overheating and carbonization of the food caused by concentrated heating on one side of the food due to position differences. By setting a carbonization sensing device to test the carbon content of the gas inside the air fryer, it can determine whether there is a risk of overheating and carbonization in the air fryer, which can improve the reliability of the heating program of the air fryer, avoid food burning, improve the working achievement rate of the air fryer, and enhance the user experience.
