Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent devices, and in particular to a heating control method for a cooking device. Background Art

[0002] Most of the cooking devices (such as rice cookers) on the market are heated by an integral heating plate. When the user adds rice and water to the inner pot, the rice will be uneven due to fluidity, that is, the rice itself is unevenly distributed, and this will also cause uneven rice-water mixing ratio in some areas. At this time, the existing rice cooker directly uses the bottom hot plate to heat the inner pot as a whole. Even if the heating of the inner pot is uniform, the uneven distribution of ingredients will cause uneven heating of the rice (the heating effect of the rice varies greatly); and, in fact, due to the limitation of the processing technology, the hot plate itself and the inner pot may have uneven thickness, resulting in uneven heat conduction effect, and the distribution of the heating element may also be uneven, which will further affect the heating uniformity of the rice. Then a temperature probe on the top measures the air temperature in the pot, making it impossible to accurately obtain the real temperature information of the rice, which leads to some problems, such as the inability to make adjustments for uneven regional heating, resulting in some areas being burnt, and some areas being undercooked.

[0003] For example, patent document CN 217987335 U discloses a heating plate assembly and a cooking utensil, which heats food more evenly by controlling a plurality of zoned heating parts to heat the food respectively. However, this method cannot accurately control the heating temperature of each zoned heating part. Summary of the invention

[0050] In order to solve the above problems, the present disclosure provides a heating control method for a cooking device. Figures 1 to 6 The heating control method of the cooking device provided in the embodiment of the present disclosure is described in detail.

[0051] Figure 1 A flow chart of a heating control method for a cooking device provided in an embodiment of the present disclosure is shown.

[0052] In the embodiment of the present disclosure, the heating control method of the cooking device can be executed by an electronic device, wherein the electronic device can be a device including a cooking device, a workstation, various devices, etc.

[0053] like Figure 1 As shown, the heating control method of the cooking device may include the following steps.

[0054] S110, according to the type of the heating plate of the cooking device, a temperature image matrix of the surface of the cooking food in the cooking device is obtained.

[0055] In the embodiment of the present disclosure, the electronic device can obtain a temperature image matrix of the surface of the cooking food in the cooking device according to the type of the heating plate of the cooking device.

[0056] Optionally, the heating plate type may be a different structure that characterizes a heating plate in a cooking device. The heating plate type may include a heating plate with at least 3 partitions.

[0057] Optionally, the temperature image matrix may be a matrix representing temperature distribution conditions at different locations on the surface of the object according to the temperature data.

[0058] Specifically, the electronic device can obtain a temperature image matrix of the surface of cooking ingredients in a cooking device (such as an electric rice cooker) according to the type of the heating plate corresponding to the heating plate used for the heating function.

[0059] S120, dividing the temperature image matrix into regions according to the type of the heating plate to obtain temperature information of multiple heating regions.

[0060] In the disclosed embodiment, the electronic device may divide the temperature image matrix into regions according to the type of the heating plate to obtain temperature information of a plurality of heating regions.

[0061] Specifically, the electronic device may determine a plurality of heating areas according to the type of the heating plate, and divide the temperature image matrix into areas, thereby obtaining temperature information of the plurality of heating areas.

[0062] S130. Determine a corresponding temperature adjustment strategy according to the temperature information of the multiple heating areas.

[0063] In the embodiment of the present disclosure, the electronic device may determine a corresponding temperature adjustment strategy according to the temperature information of the multiple heating areas.

[0064] Optionally, the temperature adjustment strategy may be a strategy for adjusting the heating power of each heating zone separately.

[0065] Specifically, the electronic device may determine a temperature adjustment strategy corresponding to each heating area according to the temperature information of the multiple heating areas.

[0066] S140: Regulate power for each of the heating areas according to the temperature regulation strategy.

[0067] In the embodiment of the present disclosure, the electronic device can adjust the power of each heating area according to the temperature adjustment strategy.

[0068] Therefore, in the embodiment of the present disclosure, it is possible to obtain the temperature image matrix of the surface of the cooking ingredients in the cooking device according to the type of the heating plate of the cooking device, and then divide the temperature image matrix into regions according to the type of the heating plate to obtain the temperature information of multiple heating regions, and then determine the corresponding temperature adjustment strategy according to the temperature information of the multiple heating regions, and finally adjust the power of each of the heating regions according to the temperature adjustment strategy. Therefore, according to the type of the heating plate of the cooking device, and obtaining the temperature image matrix of the surface of the cooking ingredients in the cooking device, the temperature information of multiple heating regions is obtained, and the corresponding temperature adjustment strategy is determined according to the temperature information of the multiple heating regions to adjust the power, so that the power of multiple heating regions is accurately adjusted according to the temperature information, ensuring uniform heating and reducing the phenomenon of undercooked and burnt food.

[0069] Optionally, S110 may specifically include: querying the model of the cooking device, and obtaining the type of the heating plate according to the model of the cooking device, the type of the heating plate including one of an eight-zone heating plate, a nine-zone heating plate and a sixteen-zone heating plate; and collecting the temperature image matrix of the surface of the cooking ingredients in the cooking device through a thermal infrared sensor.

[0070] In the embodiment of the present disclosure, the electronic device can query the model of the cooking device and obtain the type of the heating plate according to the model of the cooking device.

[0071] Among them, the heating plate type may include one of an eight-zone heating plate, a nine-zone heating plate and a sixteen-zone heating plate.

[0072] Figure 2 A schematic structural diagram of a heating plate provided in an embodiment of the present disclosure is shown.

[0073] like Figure 2As shown, the heating plate may include an eight-zone heating plate, a nine-zone heating plate and a sixteen-zone heating plate. The eight-zone heating plate may be a heating area including eight fan-shaped areas, and each heating area is provided with a separate heating element (the heating element may be a coil embedded in the heating plate to make the heating plate induction heat, or a heating element provided on the lower side of the heating plate) to achieve zone heating; the heating plate itself may be a whole, or it may be divided into several sub-blocks according to the heating area, and the adjacent sub-blocks may be in contact with each other, preferably with a gap therebetween, and the sub-blocks are not in contact with each other to reduce the influence between each other, thereby better controlling the uniformity. The heating plate can be a whole piece corresponding to the bottom surface of the inner pot, or it can also have an outer extension portion, which can correspond to the bottom corner area of ​​the inner pot and part of the side wall bottom area. This is reflected in each heating sub-block, so that the radial length of each heating sub-block increases. Because the present scheme improves uniformity through circumferential zone heating, its essence is to divide the food into multiple blocks along the circumference for separate heating, so each sub-block of food is heated by the corresponding heating sub-block. After the heating sub-block is heated in correspondence with the bottom of the inner pot, the side wall area of ​​the inner pot corresponding to the sub-block needs to be heated from the bottom. During the heat conduction, the heat is not strictly heated in the radial direction to the sub-block where it is located, but it will also be conducted to the remaining sub-blocks on both sides, weakening the control effect of heating uniformity. Therefore, the more the heating sub-block extends radially, the more heat can be conducted to the corresponding sub-block area as much as possible, and the control effect of heating uniformity is better.

[0074] The nine-zone heating plate can include eight annular areas and a central area. The central area (middle heating area) is heated as a whole, and the eight annular areas are heated by zones. The central area is mainly set up for high-heat heating in the middle, which shortens the overall cooking time and can also be used for special situations such as firewood rice and clay pot rice. The zone heating will realize independent temperature control of each zone based on the surface temperature measurement, thereby achieving effective temperature control of each zone.

[0075] The sixteen-zone heating plate may include eight annular areas and eight central areas. The central area is combined with the outer annular area. Each sub-block partition is provided with a separate heating element which can be controlled individually, thereby performing an intelligent combination. This makes the hot plate partition form amorphous and can be combined according to actual usage requirements.

[0076] Furthermore, the electronic device may collect the temperature image matrix of the surface of the cooking ingredients in the cooking device through a thermal infrared sensor.

[0077] Figure 3 A schematic structural diagram of a temperature image matrix provided by an embodiment of the present disclosure is shown.

[0078] like Figure 3As shown, the electronic device can use NxM (such as 8x7) thermal infrared sensors to collect temperature information of multiple points in the cooking device (temperature information of 56 points), and use data fitting linear interpolation to form a 640X480 temperature image matrix for the temperature information of multiple points. The temperature information of any point in the area can be viewed from the matrix.

[0079] Optionally, S120 may specifically include: according to the type of the heating plate, dividing the temperature image matrix into a plurality of heating areas of the same number corresponding to the type of the heating plate; and calculating temperature information of the plurality of heating areas respectively, wherein the temperature information includes a minimum temperature of the area, a maximum temperature of the area and an average temperature of the area.

[0080] In the embodiment of the present disclosure, the electronic device may divide the temperature image matrix into a plurality of heating areas of the same number corresponding to the type of the heating plate according to the type of the heating plate.

[0081] Specifically, the electronic device can divide the temperature image matrix into multiple heating areas of the same number corresponding to the type of heating plate according to the type of heating plate, such as an eight-zone heating plate, a nine-zone heating plate and a sixteen-zone heating plate, such as dividing the temperature image matrix into corresponding eight heating areas according to the eight sector areas of the eight-zone heating plate, dividing the temperature image matrix into corresponding eight annular heating areas and a central heating area according to the eight annular areas and a central area of ​​the nine-zone heating plate, and dividing the temperature image matrix into corresponding eight annular heating areas and eight central heating areas according to the eight annular areas and eight central areas of the sixteen-zone heating plate.

[0082] Furthermore, the electronic device may calculate temperature information of a plurality of heating areas respectively.

[0083] Optionally, the temperature information may include a regional minimum temperature, a regional maximum temperature, and a regional average temperature.

[0084] Specifically, the electronic device can calculate the temperature information of multiple heating areas separately, such as eight heating areas, eight annular heating areas and a central heating area (nine heating areas) and eight annular heating areas and eight central heating areas (sixteen heating areas), such as the minimum temperature (MinTemp) of the area, the maximum temperature (MaxTemp) of the area and the average temperature (MeanTemp) of the area.

[0085] Optionally, before S130, the heating control method of the cooking device may further include: heating the multiple heating areas at a uniform power, and acquiring temperature information of the multiple heating areas in real time.

[0086] In the embodiment of the present disclosure, at the early stage of operation, the electronic device can heat the multiple heating areas at a uniform power and obtain temperature information of the multiple heating areas in real time.

[0087] Specifically, when the cooking device starts working and in the early stage of working, the electronic device can heat multiple heating areas according to uniform power, that is, control the heating components corresponding to the multiple heating areas according to the uniform power, and collect temperature information corresponding to the multiple heating areas through thermal infrared sensors.

[0088] Optionally, S130 may specifically include: if the difference between the average temperatures of the multiple heating areas does not exceed a first preset value and the average temperature of the area is less than a second preset value, heating the multiple heating areas according to the uniform power.

[0089] In an embodiment of the present disclosure, if the difference in the average temperatures of the multiple heating areas does not exceed a first preset value and the average temperature of the areas is less than a second preset value, the electronic device can heat the multiple heating areas according to the uniform power.

[0090] Optionally, the first preset value may be a preset temperature value. For example, the first preset value may be 1°C or 2°C.

[0091] Optionally, the second preset value may be a preset temperature value, for example, the second preset value may be 95°C or 96°C.

[0092] Specifically, after obtaining the temperature information of multiple heating areas, the electronic device determines the regional average temperature (MeanTemp) of each heating area. If the difference in the regional average temperature (MeanTemp) between the heating areas does not exceed a first preset value (such as 1°C), and the regional average temperature (MeanTemp) is less than a second preset value (such as 95°C), the electronic device can heat the multiple heating areas according to the uniform power, mainly to monitor and prevent overflow.

[0093] Optionally, S130 may further specifically include: if the difference between the maximum temperature and the minimum temperature of the heating area is greater than a third preset value, reducing the heating power of the heating area.

[0094] In the embodiment of the present disclosure, if the difference between the maximum temperature of the heating area and the minimum temperature of the heating area is greater than a third preset value, the electronic device can reduce the heating power of the heating area.

[0095] Optionally, the third preset value may be a preset temperature value. For example, the third preset value may be 10°C or 11°C.

[0096] Specifically, the electronic device can calculate the difference between the maximum temperature of each heating area and the minimum temperature of the area, that is, calculate the difference between the maximum temperature of the area (MaxTemp) and the minimum temperature of the area (MinTemp). If the difference is greater than the third preset value (10°C), the electronic device can reduce the heating power of the heating area, thereby preventing overflow.

[0097] Optionally, S130 may specifically include: if the difference between the regional average temperatures of multiple heating areas exceeds a first preset value, calculating the overall average temperature of the multiple heating areas; if the regional average temperature of the heating area is lower than the overall average temperature, increasing the heating power of the heating area; if the regional average temperature of the heating area is higher than the overall average temperature, reducing the heating power of the heating area.

[0098] In an embodiment of the present disclosure, at a later stage of operation, if the difference between the regional average temperatures of multiple heating areas exceeds a first preset value, the electronic device can calculate the overall average temperature of the multiple heating areas, and if the regional average temperature of a heating area is lower than the overall average temperature, the heating power of the heating area is increased; if the regional average temperature of a heating area is higher than the overall average temperature, the heating power of the heating area is reduced.

[0099] Figure 4 A flow chart of another heating control method for a cooking device provided in an embodiment of the present disclosure is shown.

[0100] like Figure 4 As shown, in the early stage of operation, the electronic device can heat the multiple heating areas according to a uniform power, and obtain the temperature information of the multiple heating areas in real time, and then determine whether the difference in the regional average temperatures of the multiple heating areas exceeds a first preset value, and determine whether the regional average temperatures of the multiple heating areas are less than a second preset value. If the difference in the regional average temperatures of the multiple heating areas does not exceed the first preset value and the regional average temperature is less than the second preset value, the electronic device can heat the multiple heating areas according to the uniform power; if the difference in the regional average temperatures of the multiple heating areas exceeds the first preset value, the overall average temperature of the multiple heating areas is calculated, if the regional average temperature of the heating area is less than the overall average temperature, the heating power of the heating area is increased, if the regional average temperature of the heating area is greater than the overall average temperature, the heating power of the heating area is reduced; if the regional average temperature of the multiple heating areas is not less than the second preset value, the electronic device performs overflow heating processing.

[0101] Optionally, S130 may also specifically include: when the heating plate type is an eight-zone heating plate, heating the multiple heating areas at high power; if the difference in the average temperatures of the multiple heating areas exceeds a third preset value, reducing the heating power of the heating area, otherwise keeping the high power unchanged; when the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, heating the central area at the high power, and heating the annular area at a preset multiple of the high power; if the difference between the central area and the annular area exceeds a third preset value, reducing the heating power of the central area and the annular area.

[0102] In an embodiment of the present disclosure, at a later stage of operation, the electronic device can heat multiple heating areas at high power when the heating plate type is an eight-zone heating plate, and then if the difference in the average temperatures of the multiple heating areas exceeds a third preset value, the heating power of the heating area is reduced, otherwise the high power is maintained unchanged.

[0103] Furthermore, when the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, the electronic device can heat the central area according to the high power, and heat the annular area according to a preset multiple of the high power, for example, heating the annular area according to 0.8 times the high power, and if the difference between the central area and the annular area exceeds a third preset value, reduce the heating power of the central area and the annular area.

[0104] Figure 5 A flow chart of another heating control method for a cooking device provided in an embodiment of the present disclosure is shown.

[0105] like Figure 5 As shown, in the early stage of operation, the electronic device first heats the multiple heating areas according to a uniform power, and in the later stage of operation, the type of the heating plate is judged. When the heating plate type is an eight-zone heating plate, the electronic device can heat the multiple heating areas according to a high power, and if the difference in the average temperatures of the multiple heating areas exceeds a third preset value, the heating power of the heating area is reduced, otherwise the high power is kept unchanged; when the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, the electronic device can heat the central area according to the high power, and heat the annular area according to a preset multiple of the high power, and if the difference between the central area and the annular area exceeds a third preset value, the heating power of the central area and the annular area is reduced, otherwise the high power is kept unchanged.

[0106] Optionally, S130 may also specifically include: when the heating plate type is an eight-zone heating plate, if the regional average temperature of the heating area is not less than a second preset value, reducing the heating power of the heating area; when the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, if the regional average temperature of the heating area is not less than the second preset value, reducing the heating power of the annular area.

[0107] In the embodiment of the present disclosure, when the heating plate type is an eight-zone heating plate, if the average temperature of the heating area is not less than the second preset value, the heating power of the heating area is reduced. When the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, if the average temperature of the heating area is not less than the second preset value, the heating power of the annular area is reduced.

[0108] Figure 6 A flow chart of a heating control method for a cooking device provided in an embodiment of the present disclosure is shown.

[0109] like Figure 6 As shown, in the early stage of operation, the electronic device first heats the multiple heating areas according to a uniform power, and in the later stage of operation, the type of the heating plate is determined. When the heating plate type is an eight-zone heating plate, the electronic device can heat the multiple heating areas according to high power. When the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, the electronic device can heat the central area according to the high power, and heat the annular area according to a preset multiple of the high power. When the heating plate type is an eight-zone heating plate, it is determined whether the regional average temperature of the heating area is not less than a second preset value. If the regional average temperature of the heating area is not less than the second preset value, the heating power of the heating area is reduced, otherwise the high power is maintained unchanged; when the heating plate type is a nine-zone heating plate or a sixteen-zone heating plate, if the regional average temperature of the heating area is not less than the second preset value, the heating power of the annular area is reduced, otherwise the high power is maintained unchanged.
