Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a cooking mode recognition method, a cooking mode recognition device, a computer-readable storage medium, and a multifunctional cooking platform. Background Technology

[0002] A multi-functional cooking platform is a cooking platform that can directly place different carriers to achieve different cooking functions. For example, different carriers can be pots, pans, etc. Its working principle is to use electromagnetic induction heating to heat different carriers.

[0003] Because the structures of a pot and a cookware are different, the heating temperatures used on different platforms differ. Current cooking platforms have limitations; they cannot accurately distinguish between a cookware and a pot placed on the platform. This inaccurate identification can damage the cookware or even create safety hazards. For example, when the current working mode is set to induction cooker mode, but a pot is actually placed on the cooking platform, the pot's base cannot withstand temperatures exceeding 130℃, while the default oil temperature in induction cooker mode reaches 200℃. After the moisture inside the pot evaporates, prolonged dry-cooking or simmering can cause the pot's base to melt or even catch fire, posing a safety risk to the user. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, the first objective of this invention is to propose a cooking mode recognition method. By comparing the power difference between the target power and the actual power with a preset power threshold, it is possible to determine whether the cooking mode of a multi-functional cooking platform is correct, thereby effectively avoiding damage to cooking appliances caused by incorrect cooking modes and preventing safety hazards arising from incorrect cooking modes.

[0005] The second objective of this invention is to provide a cooking pattern recognition device.

[0006] A third objective of this invention is to provide a computer-readable storage medium.

[0007] The fourth objective of this invention is to provide a multifunctional cooking platform.

[0008] To achieve the above objectives, a first aspect of the present invention provides a cooking mode recognition method applied to a multi-functional cooking platform. The method includes: if the current cooking mode of the multi-functional cooking platform is detected to be a first preset mode, determining a corresponding target power, and controlling the multi-functional cooking platform to heat the cooking appliance with a fixed duty cycle according to the target power; obtaining the actual power of the multi-functional cooking platform; and when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, determining that the current cooking mode of the multi-functional cooking platform is incorrect, and switching the current cooking mode to a second preset mode.

[0009] According to the cooking mode recognition method of this invention, if the current cooking mode of the multi-functional cooking platform is detected to be a first preset mode, a corresponding target power is first determined, and the multi-functional cooking platform is controlled to heat the cooking appliance with a fixed duty cycle according to the target power. Then, the actual power of the multi-functional cooking platform is obtained. Finally, when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, it is determined that the current cooking mode of the multi-functional cooking platform is incorrect, and the current cooking mode is switched to a second preset mode. Thus, by comparing the power difference between the target power and the actual power with a preset power threshold, this method can determine whether the cooking mode of the multi-functional cooking platform is correct, thereby effectively avoiding damage to the cooking appliance caused by an incorrect cooking mode and preventing safety hazards caused by an incorrect cooking mode.

[0010] In addition, the cooking pattern recognition method according to the above embodiments of the present invention may also have the following additional technical features:

[0011] According to one embodiment of the present invention, determining the target power includes: acquiring the power level of the multi-functional cooking platform when it is operating in a first preset mode; and determining the target power based on the power level.

[0014] According to one embodiment of the present invention, the preset power threshold is determined based on the minimum resolution corresponding to the power level.

[0015] According to one embodiment of the present invention, when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, the above method further includes: determining the temperature change value of the cooking appliance on the multi-functional cooking platform, so as to determine that the current cooking mode of the multi-functional cooking platform is incorrect when the temperature change value is less than or equal to a preset temperature threshold.

[0016] According to one embodiment of the present invention, when the temperature change value is greater than a preset temperature threshold, or when the power difference is less than a preset power threshold, the current cooking mode of the multi-functional cooking platform is determined to be correct.

[0017] According to one embodiment of the present invention, before determining the corresponding target power if the current cooking mode of the multi-functional cooking platform is detected to be a first preset mode, the method further includes: if no communication signal between the multi-functional cooking platform and the cooking appliance is detected, determining that the current cooking mode of the multi-functional cooking platform is a first preset mode; if a communication signal between the multi-functional cooking platform and the cooking appliance is detected, determining that the current cooking mode of the multi-functional cooking platform is a second preset mode.

[0019] According to an embodiment of the present invention, a cooking mode recognition device, upon detecting that the current cooking mode of a multi-functional cooking platform is a first preset mode, determines a corresponding target power and controls the multi-functional cooking platform to heat the cooking appliance with a fixed duty cycle based on the target power. An acquisition module acquires the actual power of the multi-functional cooking platform. When the power difference between the target power and the actual power is greater than or equal to a preset power threshold, the control module determines that the current cooking mode of the multi-functional cooking platform is incorrect and switches the current cooking mode to a second preset mode. Thus, by comparing the power difference between the target power and the actual power with the preset power threshold, the device can determine whether the cooking mode of the multi-functional cooking platform is correct, thereby effectively avoiding damage to the cooking appliance caused by an incorrect cooking mode and preventing safety hazards caused by an incorrect cooking mode. To achieve the above objective, a third aspect of the present invention provides a computer-readable storage medium storing a cooking mode recognition program, which, when executed by a processor, implements the above-described cooking mode recognition method.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following description, with reference to the accompanying drawings, outlines the cooking pattern recognition method, cooking pattern recognition device, computer-readable storage medium, and multifunctional cooking platform proposed in embodiments of the present invention.

[0032] In one embodiment of the present invention, the multi-functional cooking platform can be an induction cooker. Cooking utensils such as pots and pans are placed in the working area of ​​the induction cooker, and the induction cooker heats the cooking utensils. The working modes of the multi-functional cooking platform can include an induction cooker mode and a pot mode. The induction cooker mode is used to directly heat the pots (such as iron pots, non-stick pots, aluminum pots, etc.), and the pot mode is used to directly heat the pot (such as rice cookers, etc.).

[0033] In one embodiment of the present invention, due to the structural differences between the pot body and the cookware, the working mode of the multi-functional cooking platform can be determined by utilizing the structure of the cooking appliance. Generally, such as... Figure 2 As shown, the base of the pot body integrates a reed switch communication module, while cookware does not. Therefore, after placing a cooking appliance on the platform, the type of cooking appliance is determined by detecting the presence of a reed switch communication signal. If a communication signal is detected, the cooking appliance placed on the multi-functional cooking platform is considered a pot body, and the multi-functional cooking platform enters pot body mode; if no communication signal is detected, the cooking appliance placed on the multi-functional cooking platform is considered a cookware, and the multi-functional cooking platform enters induction cooker mode.

[0034] However, in practice, due to assembly errors in structural components, the pot body cannot be completely and perfectly engaged when placed on the multi-functional heating platform. This can lead to a failure of the reed switch communication module to connect properly. Specifically, the reed switch communication module at the bottom of the pot body cannot successfully establish a communication connection with the communication module on the multi-functional cooking platform. This causes the platform to mistakenly identify the cooking appliance as a pot, triggering it to enter induction cooker mode. Since the pot body base has a temperature resistance of no more than 130℃, while the default operating oil temperature in induction cooker mode reaches 200℃, there is a risk of the base melting or even catching fire during prolonged dry-cooking and simmering of rice after the moisture inside the pot evaporates.

[0035] After determining the operating mode of the multi-functional cooking platform, users can configure cooking parameters, such as heating power and heating time, via the control panel. It is understood that the function buttons on the control panel can be either touch-sensitive or mechanical buttons; no specific restrictions are made here.

[0036] Figure 1 This is a flowchart of a cooking pattern recognition method according to an embodiment of the present invention.

[0037] like Figure 1 As shown, the cooking pattern recognition method of this invention may include the following steps:

[0038] S1. If the current cooking mode of the multi-functional cooking platform is detected to be the first preset mode, determine the corresponding target power, and control the multi-functional cooking platform to heat the cooking appliance with a fixed duty cycle according to the target power.

[0039] According to one embodiment of the present invention, before determining the corresponding target power if the current cooking mode of the multi-functional cooking platform is detected to be a first preset mode, the method further includes: if no communication signal between the multi-functional cooking platform and the cooking appliance is detected, determining that the current cooking mode of the multi-functional cooking platform is a first preset mode; if a communication signal between the multi-functional cooking platform and the cooking appliance is detected, determining that the current cooking mode of the multi-functional cooking platform is a second preset mode.

[0040] Specifically, cooking utensils such as pots and pans can be directly placed on the multi-functional cooking platform to meet different cooking needs. The type of cooking utensil can be identified by detecting the communication signal of the reed switch communication module, which is integrated into both the multi-functional cooking platform and the pan. When no communication signal is detected, the cooking utensil placed on the heating platform is determined to be a pot, and the cooking mode is set to the first preset mode (induction cooker mode). When a communication signal is detected, the cooking utensil placed on the heating platform is determined to be a pan, and the cooking mode is set to the second preset mode (pan mode).

[0041] According to one embodiment of the present invention, determining the target power includes: acquiring the power level of the multi-functional cooking platform when it is operating in a first preset mode; and determining the target power based on the power level.

[0042] According to one embodiment of the present invention, determining the target power based on the power level includes: taking the maximum heating power corresponding to the power level as the target power.

[0043] Specifically, when the cooking mode of the multi-functional cooking platform is determined to be the first preset mode, the system receives and responds to the user's power level trigger command, and determines the target power of the cooking appliance based on the user's power level trigger command. For example, the first preset mode can be set to five power levels: a first power level, a second power level, a third power level, a fourth power level, and a fifth power level. The heating power of the first power level is 0-400W, the second power level is 400W-800W, the third power level is 800W-1200W, the fourth power level is 1200W-1600W, and the fifth power level is 1600W-2000W. The heating power of each setting is adjustable. For example, the heating power of the fifth setting is 1600W-2000W, with a minimum heating power of 1600W and a maximum heating power of 2000W. After obtaining the current power setting, the maximum heating power corresponding to that power setting is used as the target power so that when the temperature of the bottom of the cooking pot changes, the temperature change is more obvious, thus improving the accuracy of pattern recognition.

[0044] According to one embodiment of the present invention, controlling a multi-functional cooking platform to heat at a fixed duty cycle based on a target power includes: determining the on-state width of a power switch tube in the multi-functional cooking platform based on the target power; and controlling the on-state width of the power switch tube to remain constant so that the multi-functional cooking platform heats at a fixed duty cycle.

[0045] Specifically, the multi-functional cooking platform operates on the principle of electromagnetic heating. Its fundamental principle is to control the switching width of the IGBTs to determine the heating power, such as... Figure 3 As shown in the diagram, the free resonant frequency period Toff is fixed and determined by the cooking appliance and the value of the coupling inductance. Therefore, the heating power can be determined by Ton. When the type of cooking appliance is determined, the larger the opening width of the power switch tube, the higher the heating power of the multi-functional cooking platform. When the opening width of the power switch tube is fixed, the distance between the cooking appliance and the heating coil in the multi-functional cooking platform, i.e., the coupling distance, will affect the heating power. Specifically, the larger the coupling distance, the smaller the actual power obtained for the same opening width; the smaller the coupling distance, the larger the actual power obtained for the same opening width.

[0046] Since the cooking appliance is placed directly on the heating area of ​​the multi-functional cooking platform, when the appliance is a pot, the coupling distance is approximately zero, and the difference between the actual power and the preset power is zero. However, when the appliance is a casserole dish, due to the 4-5mm structural cavity separating the inner pot from the outer pot, the coupling distance differs significantly, resulting in a large difference between the actual power and the preset power. By keeping the power switch's on-state width constant, the induction cooker heats the appliance with a fixed duty cycle. This facilitates the calculation of the difference between the actual power and the target power of the multi-functional cooking platform, thereby further determining whether the current cooking mode of the multi-functional cooking platform is incorrect.

[0047] S2, obtain the actual power of the multi-functional cooking platform.

[0048] S3: When the power difference between the target power and the actual power is greater than or equal to a preset power threshold, the current cooking mode of the multi-functional cooking platform is determined to be incorrect, and the current cooking mode is switched to the second preset mode. The preset power threshold is determined based on the minimum resolution corresponding to the power level.

[0049] Specifically, after obtaining the actual power and target power of the multi-functional cooking platform through the above embodiments, the power difference between the two is obtained. When the power difference is greater than or equal to a preset power threshold, it indicates that the actual power of the multi-functional cooking platform cannot reach the target power under the condition that the IGBT turn-on width is determined. At this time, it is considered that the current cooking mode of the multi-functional cooking platform is incorrect, that is, the current cooking mode is not compatible with the cooking appliance. For example, when it is determined that the multi-functional cooking platform is working in the first preset mode, the preset target power of the multi-functional cooking platform is P, the obtained actual power of the multi-functional cooking platform is P', and the power difference between the target power and the actual power is ΔP, then ΔP = PP'. Wherein, P' = K * P", K is the minimum resolution of the power level, and P" is the sampling value. It should be noted that the minimum resolution corresponding to different power levels can be the same or different. Taking the minimum resolution of 100W as an example, the power difference between the target power and the actual power is ΔP = P - 100 * P". When ΔP ≥ 100 * N (preset power threshold), it is determined that the current cooking mode is incorrect and the cooking mode is incompatible with the cooking appliance. After determining that the current cooking mode is incorrect, the current cooking mode is switched to the second preset mode. Here, N ≥ 1, and the value of N is related to the coupling distance. The larger the coupling distance, the larger the value of N. The coupling distance refers to the distance between the heating coil of the multi-functional cooking platform and the cooking appliance.

[0050] However, in actual use, cooking appliances may be misplaced. In such cases, simply determining that the current cooking mode is incorrect based on the difference between the target power and the actual power being greater than or equal to a preset power threshold may lead to misjudgment. For example, if the center of the pot is more than a certain distance from the center of the heating area of ​​the multi-functional cooking platform, the actual power may not reach the target power. Considering that different cooking appliances are made of different materials and have different heat transfer rates—a normally used pot has a relatively fast heat transfer rate and will show a certain temperature change in a short time, while the bottom of the pot is made of plastic and has a very slow heat transfer rate, resulting in no significant temperature change in a short time—it is also possible to further determine whether the previous cooking mode is incorrect based on the temperature change values ​​of the cooking appliances placed on the multi-functional cooking platform, thereby improving the accuracy of mode recognition.

[0051] According to one embodiment of the present invention, when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, the method further includes: determining the temperature change value of the cooking appliance on the multi-functional cooking platform, so as to determine that the current cooking mode of the multi-functional cooking platform is incorrect when the temperature change value is less than or equal to a preset temperature threshold. The preset temperature threshold can be determined according to actual conditions.

[0052] Specifically, to prevent the cooking appliance from dry-burning and deforming due to prolonged heating by the multi-functional cooking platform, which could lead to fires and other safety issues, the temperature change detection can monitor short-term temperature changes. For example, it can detect the temperature change within one minute of the appliance starting to heat up. When the temperature change is less than or equal to a preset temperature threshold, the temperature change is considered insignificant. This eliminates the possibility of the cookware being misaligned (because even if the cookware is misaligned, if it's a pot, even if its actual power doesn't reach the target power, the temperature change will be more noticeable; if it's a clay pot, the actual power won't reach the target power, and the temperature change will be less noticeable). This confirms that the current cooking appliance is a clay pot, thus indicating that the current cooking mode is incorrect.

[0053] In one embodiment of the present invention, the temperature change value can be directly measured by the temperature probe at the bottom of the multi-functional cooking platform, or it can be determined according to the conversion method between heat and temperature. The temperature change value is determined using the energy-temperature conversion formula. Taking boiling water as an example, the specific heat capacity of water is 4200 J / (kg·℃), and the heat is Q = Pt. Where P is power in watts (W) and t is time (1 min as an example in seconds), then the temperature change value ΔT = P * 60 / 4200 / 2 N / m. For example, when the mass of water is 2 kg, N = 1, and the initial power is 1000 W, ΔT = 1000 * 60 / 4200 / 2 / 2 ≈ 3.5℃, the temperature change is very small. Therefore, when the multi-functional cooking platform initially starts working, it can be heated at the maximum power setting. At this time, ΔT = 2000 * 60 / 4200 / 2 / 2 ≈ 7℃, and the temperature change can be clearly observed, facilitating the judgment of the cooking appliance.

[0054] It should be noted that, to ensure noticeable temperature changes, after confirming the operating mode, heating is performed at the maximum power setting. Temperature change detection measures temperature changes over a short period. When heating at other maximum power settings, temperature changes are detected over a longer period. For example, when heating at the maximum power of 400W in the first power setting, temperature changes can be detected over 10 minutes; when heating at the maximum power of 2000W in the fifth power setting, temperature changes can be detected over 1 minute. Detecting short-term temperature changes at higher power settings helps prevent the cooking appliance from dry-burning.

[0055] Therefore, when the power difference ΔP is greater than or equal to the preset power threshold and the temperature change ΔT is less than or equal to the preset temperature threshold, the current cooking mode is considered to be incorrect. The multi-functional cooking platform is then controlled to exit the heating mode. At the same time, the display panel can show an error message and indicate that the product is not placed correctly, avoiding the risk of the pot body being heated in the first preset mode, which could lead to the pot body base melting and catching fire due to dry burning. This achieves protection against entering the wrong cooking mode due to improper placement of the pot body. Furthermore, when it is confirmed that the current cooking mode is incorrect, the current cooking mode is switched from the first preset mode to the second preset mode to ensure the normal use of the multi-functional cooking platform.

[0056] According to one embodiment of the present invention, when the temperature change value is greater than a preset temperature threshold, or when the power difference is less than a preset power threshold, the current cooking mode of the multi-functional cooking platform is determined to be correct.

[0057] In other words, when the power difference is less than the preset power threshold, it is considered that the actual power is almost at the target power. At this time, the current mode is considered to be correct, and it continues to work according to the normal control logic. There is no need to judge the temperature change of the cooking appliance. When the power difference is greater than or equal to the preset power threshold and the temperature change value is greater than the preset temperature threshold, the current cooking mode is considered to be correct, but the pot is placed off-center. The user can be reminded to reposition the pot.

[0058] As a concrete example, such as Figure 4 As shown, the cooking pattern recognition method of the present invention may include the following steps:

[0059] S201, determine the target power P of the multi-functional cooking platform.

[0060] S202, obtain the actual power of the multi-functional cooking platform as P'.

[0061] S203, calculate the power difference ΔP between the target power and the actual power.

[0062] S204. Determine whether △P≥100*N is true. If yes, proceed to step S205; otherwise, proceed to step S208.

[0063] S205, detect the temperature change △T of a cooking appliance after heating for one minute.

[0064] S207, determine whether △T≤P*60 / 4200 / 2N / m is true. If yes, proceed to step S207; otherwise, proceed to S208.

[0065] S207, Multifunctional cooking platform error message, heating stopped.

[0066] S208, the multi-functional cooking platform is working normally.

[0067] In summary, according to the cooking mode recognition method of this invention, if the current cooking mode of the multi-functional cooking platform is detected to be a first preset mode, the corresponding target power is first determined, and the multi-functional cooking platform is controlled to heat the cooking appliance with a fixed duty cycle according to the target power. Then, the actual power of the multi-functional cooking platform is obtained. Finally, when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, it is determined that the current cooking mode of the multi-functional cooking platform is incorrect, and the current cooking mode is switched to a second preset mode. Therefore, by comparing the power difference between the target power and the actual power with a preset power threshold, this method can determine whether the cooking mode of the multi-functional cooking platform is correct, thereby effectively avoiding damage to the cooking appliance caused by incorrect cooking modes and preventing safety hazards caused by incorrect cooking modes.

[0068] Corresponding to the above embodiments, the present invention also proposes a cooking mode recognition device.

[0069] like Figure 5 As shown, the cooking mode recognition device 100 of this embodiment may include a control module 110 and an acquisition module 120.

[0070] The control module 110 is used to determine the corresponding target power when it detects that the current cooking mode of the multi-functional cooking platform is a first preset mode, and to control the multi-functional cooking platform to heat the cooking appliance with a fixed duty cycle according to the target power. The acquisition module 120 is used to acquire the actual power of the multi-functional cooking platform. The control module 110 is also used to determine that the current cooking mode of the multi-functional cooking platform is incorrect when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, and to switch the current cooking mode to a second preset mode.

[0071] According to one embodiment of the present invention, the control module 110 determines the target power, specifically for: acquiring the power level of the multi-functional cooking platform when it is working in a first preset mode; and determining the target power based on the power level.

[0072] According to one embodiment of the present invention, the control module 110 determines the target power according to the power level, specifically: taking the maximum heating power corresponding to the power level as the target power.

[0073] According to one embodiment of the present invention, the control module 110 controls the multi-functional cooking platform to heat with a fixed duty cycle according to the target power, specifically for: determining the on-state width of the power switch tube in the multi-functional cooking platform according to the target power; and controlling the on-state width of the power switch tube to remain unchanged so that the multi-functional cooking platform heats with a fixed duty cycle.

[0074] According to one embodiment of the present invention, the preset power threshold is determined based on the minimum resolution corresponding to the power level.

[0075] According to one embodiment of the present invention, when the power difference between the target power and the actual power is greater than or equal to a preset power threshold, the control module 110 is further configured to: determine the temperature change value of the cooking appliance on the multi-functional cooking platform, so as to determine that the current cooking mode of the multi-functional cooking platform is incorrect when the temperature change value is less than or equal to a preset temperature threshold.

[0076] According to one embodiment of the present invention, the control module 110 is further configured to determine that the current cooking mode of the multi-functional cooking platform is correct when the temperature change value is greater than a preset temperature threshold, or when the power difference value is less than a preset power threshold.

[0077] According to one embodiment of the present invention, the control module 110 is further configured to determine the current cooking mode of the multi-functional cooking platform as a first preset mode if no communication signal between the multi-functional cooking platform and the cooking appliance is detected; and to determine the current cooking mode of the multi-functional cooking platform as a second preset mode if a communication signal between the multi-functional cooking platform and the cooking appliance is detected.

[0078] It should be noted that for details not disclosed in the cooking pattern recognition device of this embodiment, please refer to the details disclosed in the cooking pattern recognition method of this embodiment, which will not be repeated here.

[0079] According to an embodiment of the cooking mode recognition device of the present invention, when the current cooking mode of the multi-functional cooking platform is detected to be a first preset mode, the control module determines the corresponding target power and controls the multi-functional cooking platform to heat the cooking appliance with a fixed duty cycle according to the target power. The acquisition module acquires the actual power of the multi-functional cooking platform. When the power difference between the target power and the actual power is greater than or equal to a preset power threshold, the control module determines that the current cooking mode of the multi-functional cooking platform is incorrect and switches the current cooking mode to a second preset mode. Thus, by comparing the power difference between the target power and the actual power with the preset power threshold, the device can determine whether the cooking mode of the multi-functional cooking platform is correct, thereby effectively avoiding damage to the cooking appliance caused by incorrect cooking modes and preventing safety hazards caused by incorrect cooking modes.

[0080] Corresponding to the above embodiments, the present invention also proposes a computer-readable storage medium.

[0081] The present invention provides a computer-readable storage medium having a cooking pattern recognition program stored thereon, which, when executed by a processor, implements the cooking pattern recognition method described above.

[0082] The computer-readable storage medium of this invention, by executing the above-described cooking mode recognition method, can determine whether the cooking mode of the multi-functional cooking platform is correct, thereby effectively avoiding damage to cooking appliances caused by incorrect cooking modes and preventing safety hazards caused by incorrect cooking modes. Corresponding to the above embodiments, this invention also proposes a multi-functional cooking platform.
