Description

Technical Field

[0001] The present application relates to the technical field of air fryers, and in particular to a control method for an air fryer. Background Art

[0002] At present, with the development of science and technology, air fryers are more and more widely used in people's daily life. Air fryers are generally preset with different food functions, such as chicken wings function, French fries function, egg tart function, etc., and each food function machine has specific cooking parameters preset. Since the cooking parameters corresponding to each food function are generally obtained through experimental debugging of standard weight food, when users use air fryers, if the weight of the food cooked is different from the standard food weight, they often get different cooking effects. When the weight of the food placed in the air fryer is less than the standard food weight, the food is easy to burn when baked; when the weight of the food placed in the air fryer is greater than the standard food weight, the food baking effect is poor, and it may even be underbaked.

[0003] In order to solve the problem of poor cooking consistency when the weight of the ingredients being baked is different in the existing air fryer, the prior art proposes an air fryer with a weight detection function, which can detect the weight of the ingredients before cooking begins and adjust the cooking parameters according to the weight of the ingredients. Although this solution can solve the influence of the amount of ingredients on the cooking effect to a certain extent, it is necessary to reset the ingredient container to zero before cooking begins, otherwise the accurate weight of the ingredients cannot be obtained. Due to the added operation steps, the user experience is not good. Moreover, if the user forgets to perform the zeroing operation, the detected weight of the ingredients does not match the actual weight of the ingredients, and the phenomenon of the ingredients being burnt also occurs from time to time. In addition, when the user cooks different types of ingredients at the same time, for example, the user will bake chicken wings and chicken legs together, at this time the weight detection device can only distinguish the total weight of the ingredients but cannot distinguish the individual weight of each ingredient, and the cooking parameters required for baking chicken wings and chicken legs are different. If the chicken wings or chicken legs function is selected for baking, it is likely that a perfect cooking effect cannot be obtained.

[0004] Through the above analysis, it can be seen that when the ingredients placed in the pot of the existing air fryer are in a non-standard state (the standard state is that the ingredients corresponding to the function of placing a standard amount of ingredients in the pot), the cooking program cannot be adjusted in time according to the condition of the ingredients, resulting in insufficient intelligence in the cooking of the ingredients and poor cooking consistency of the ingredients. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a control method for an air fryer, which can solve the problem of poor cooking consistency when the air fryer cooks non-standard ingredients.

[0006] The present application provides a control method for an air fryer, wherein the air fryer comprises a pot body and a hot air component, wherein the hot air component delivers hot air into the pot body, wherein the hot air component comprises a heating element and a fan, wherein a weighing unit is arranged below the pot body, and the air fryer comprises a food function key. The control method for the air fryer comprises:

[0007] After the air fryer starts cooking, the hot air component works according to the standard cooking parameters corresponding to the food function selected by the user;

[0008] The weighing unit monitors the weight of the pot in real time;

[0009] Compare the weight loss slope of the target period with the standard threshold corresponding to the food function selected by the user to determine whether the food in the pot is in a standard state;

[0010] If the food in the pot is in a standard state, the hot air component continues to work according to the standard cooking parameters. If the food in the pot is in a non-standard state, the standard cooking parameters are adjusted to obtain adjusted cooking parameters, and the hot air component continues to work according to the adjusted cooking parameters.

[0011] In one embodiment, the air fryer has a temperature rise phase and a constant temperature phase that are performed sequentially, and the target time period is in the constant temperature phase.

[0012] In one embodiment, the power of the heating element is constant and the speed of the fan is constant to obtain the weight loss slope in the target period.

[0013] In one embodiment, the target time period includes a first time period between a start time and a first time period, and the standard threshold includes a first threshold. If the weight loss slope of the first time period is greater than or equal to the first threshold, it indicates that the food is in a non-standard state, and the standard cooking parameters are adjusted down to obtain the adjusted cooking parameters.

[0014] In one embodiment, the target time period also includes a second time period between the first moment and the second moment, the standard threshold includes a second threshold, if the weight loss slope of the first time period is less than the first threshold, the hot air component works according to the standard cooking parameters until the second moment, and the weight loss slope of the second time period is compared with the second threshold;

[0015] If the weight loss slope in the second period is greater than or equal to the second threshold, it indicates that the food is in a standard state, and the hot air component continues to work according to the standard cooking parameters;

[0016] If the weight loss slope in the second period is less than the second threshold, it indicates that the food is in a non-standard state, and the standard cooking parameter is increased to obtain the adjusted cooking parameter.

[0017] In one embodiment, within a first time period before the end of cooking, if the weight loss slope per unit time period is less than or equal to a third threshold, the air fryer is controlled to end cooking.

[0018] In one embodiment, within a first time period before the end of cooking, if the weight loss slope per unit time period is greater than a third threshold and less than or equal to a fourth threshold, the fan is controlled to reduce its speed.

[0019] In one embodiment, the first duration is 2 minutes to 5 minutes.

[0020] In one embodiment, the unit time length is 2s-10s.

[0021] In one embodiment, the air fryer further has a display unit, and after the adjusted cooking parameters are obtained, the adjusted cooking parameters are displayed through the display unit.

[0022] In the scheme of the present application, the weight of the pot is monitored in real time after cooking starts, and the weight loss of the pot during the cooking process is used to determine whether the ingredients are in a standard state, and the cooking parameters are adjusted according to the determination results. In this way, it can be ensured that the air fryer can achieve good cooking results when different amounts of ingredients are placed, ensuring the user experience. Since the weight loss is different when the same cooking parameters are used to cook the same kind of ingredients of different weights, and the weight loss is also different when the same cooking parameters are used to cook different ingredients of the same weight, it is possible to determine whether the ingredients placed in the pot are in a standard state by the weight loss of the ingredients, and to adjust the cooking parameters accordingly when the ingredients are in a non-standard state, eliminating the influence of the ingredients on the cooking effect. At the same time, the present application determines the weight of the ingredients by detecting the weight loss of the ingredients, without knowing the exact weight of the ingredients in the air fryer, so there is no need to perform a "zeroing operation" before cooking begins, which reduces the difficulty of user interaction and improves the user experience.

[0031] Please refer to Figure 1 , which is a connection diagram of the air fryer 1 provided in this application. Please refer to Figure 2 , which is a schematic diagram of the structure of the control unit 100 provided in this application. Figure 1 As shown, the present application provides an air fryer 1, and the air fryer 1 in the present application has a pot body, a hot air component 10 and a weighing unit 20. The hot air component 10 includes a heating element 11 and a fan 12; the hot air component 10 is arranged in the pot body, and the hot air component 10 is used to transport hot air into the pot body; the weighing unit 20 is arranged below the pot body, and the weighing unit 20 is used to measure the total weight of the pot body and the food in the pot body. In addition, the air fryer 1 is also provided with a food function key.

[0032] like Figure 1 As shown, the air fryer 1 further includes a control unit 100, which is connected to the hot air assembly 10 and the weighing unit 20 respectively. The control unit 100 is used to execute the control method of the air fryer 1 provided in the following embodiment. Specifically, Figure 2 As shown, the control unit 100 includes: at least one processor 120 and a memory 130, Figure 2 A processor 120 is taken as an example. The processor 120 and the memory 130 are connected via a bus 110. The memory 130 stores instructions that can be executed by the processor 120, and the instructions are executed by the processor 120.

[0033] The memory 130 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable red-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, disk or optical disk.

[0034] Please refer to Figure 3 , which is a flow chart of the control method of the air fryer 1 of the present application. Figure 3 As shown, the method includes the following steps S210 to S240. The working principle of the method is explained in detail below:

[0035] Step S210: After the air fryer 1 starts cooking, the hot air component 10 works according to the standard cooking parameters corresponding to the food function selected by the user.

[0036] In this step, when the user uses the air fryer 1 to cook the ingredients, before cooking begins, the ingredients need to be placed in the pot of the air fryer 1. After the ingredients are placed successfully, the user will select the ingredient function on the control end of the air fryer 1, and the control unit 100 of the air fryer 1 will receive the ingredient function information selected by the user, and call up the standard cooking parameters corresponding to the ingredient function, including cooking time, cooking temperature and other information. After cooking starts, the control unit 100 controls the heating element 11 and the fan 12 to work according to the standard cooking parameters, and synchronously executes step S220. Among them, the ingredient function selected by the user can be the ingredient function selected by the user on the operation interface of the air fryer 1, or it can be the ingredient function selected by the user on the control software of the mobile control end of the air fryer 1.

[0037] Step S220: the weighing unit 20 monitors the weight of the pot in real time.

[0038] In this step, while the heating element 11 and the fan 12 of the air fryer 1 are working, the weighing unit 20 of the air fryer 1 monitors the weight of the pot body (including the food) in real time, and feeds back the monitoring result to the control unit 100 in real time.

[0039] Specifically, the heating element 11 heats the air in the pot body of the air fryer 1, and then the fan 12 continuously blows the hot air to the surface of the food, and uses the continuously circulating hot air to transfer the heat to the surface of the food by thermal convection; after the heat accumulates on the surface of the food, the high-temperature surface of the food heats the inside of the food by heat transfer. After heating, the evaporation of water inside the food will cause the total weight of the pot body to decrease, and the weighing unit 20 will feed back the weight of the pot body to the control unit 100 in real time. It can be understood that step S220 can be executed synchronously with step S210, and step S220 can also be executed after a period of time after step S210 is executed. In addition, in the present application, the weight of the pot body refers to the weight of the pot body (including the food).

[0040] Step S230: Compare the weight loss slope of the target period with the standard threshold corresponding to the food function selected by the user to determine whether the food in the pot is in a standard state.

[0041] In this step, the control unit 100 retrieves the standard threshold corresponding to the food function according to the food function selected by the user, calculates the weight loss slope of the target time period, and compares the weight loss slope with the standard threshold to determine whether the food is in a standard state. Among them, the weight loss slope of the target time period is the ratio of the weight loss of the pot body in the target time period to the duration of the target time period. The standard state of food means that the food placed in the pot body is the food corresponding to the food function of the standard amount. It can be understood that the standard cooking parameters corresponding to each food function of the air fryer 1 are debugged with a standard amount of food as the experimental object. In addition, the determination by the control unit 100 that the food is in a standard state is only the determination result of the control unit 100, and does not mean that the food placed in the pot body must be in a standard state.

[0042] The principle by which the control unit 100 can determine whether the food is in a standard state according to the weight loss during the target period will be described in detail below:

[0043] (1) If the amount of food placed in the air fryer 1 is large:

[0044] In the early stage of cooking, due to the large amount of food in the pot, the temperature of the food rises slowly, the rate of water release from the food is slow, the weight loss of the pot is small, and the weight loss of the pot is slow. In the middle stage of cooking, the temperature of the food gradually rises, the rate of water release from the food accelerates, and the weight loss of the pot gradually increases. In the late stage of cooking, there is less water in the food, and the weight loss of the pot gradually decreases.

[0045] (2) If the amount of food placed in the air fryer 1 is small:

[0046] In the early and middle stages of cooking, the temperature of the ingredients rises faster, the water inside the ingredients is released faster, and the weight loss of the pot is faster. In the late stage of cooking, the water inside the ingredients is less, and the weight loss of the ingredients gradually decreases.

[0047] From the above content, it can be seen that when the amount of food placed in the air fryer 1 is small, the food loses more water in the early and middle stages of cooking, loses weight faster, and loses water slower in the later stages. When the amount of food placed in the air fryer 1 is large, the food loses water slower in the early stages of cooking, loses water faster in the middle stages, and loses water slower in the later stages. It can be seen from this that when the amount of food placed in the air fryer 1 is different, the weight loss of the pot body will show different trends. Based on this, the control unit 100 can determine whether the food in the pot body is in a standard state by comparing the weight loss slope of the pot body in the target period with the standard threshold. It can be understood that the standard threshold corresponding to each food function is pre-stored in the control unit 100 of the air fryer 1, and the standard threshold corresponding to each food function is obtained by placing food in a standard state in the air fryer 1 and testing the standard cooking parameters corresponding to the food function.

[0048] After determining whether the food in the air fryer 1 is in a standard state, the control unit 100 executes step S240.

[0049] Step S240: If the food in the pot is in a standard state, the hot air component 10 continues to work according to the standard cooking parameters. If the food in the pot is in a non-standard state, the standard cooking parameters are adjusted to obtain adjusted cooking parameters, and the hot air component 10 continues to work according to the adjusted cooking parameters.

[0050] In this step, the control unit 100 determines at which cooking parameters the hot air component 10 continues to work according to the judgment result of whether the food is in the standard state in step S230: if it is judged in step S230 that the food is in the standard state, the control unit 100 controls the hot air component 10 to continue working according to the standard cooking parameters; if it is judged in step S230 that the food is in a non-standard state, the control unit 100 adjusts the standard cooking parameters according to the judgment result and controls the hot air component 10 to continue working according to the adjusted cooking parameters.

[0051] From the above content, it can be seen that in the solution of the present application, the weighing unit 20 monitors the weight of the pot body in real time after cooking starts, and determines whether the food is in a standard state according to the weight loss of the food during the cooking process, and adjusts the cooking parameters according to the determination result. In this way, it can ensure that the air fryer 1 can achieve a good cooking effect when different amounts of food are put in, and ensure the user experience. At the same time, the present application determines the weight of the food by detecting the weight loss of the food, and there is no need to know the exact weight of the food in the air fryer 1, so there is no need to perform a "zeroing operation" before cooking starts, which reduces the difficulty of user interaction and improves the user experience.

[0052] In a preferred embodiment of the present application, the air fryer 1 has a heating stage and a constant temperature stage that are performed successively, and the target time period is in the constant temperature stage. During the heating stage, the heating element 11 of the air fryer 1 works continuously to quickly raise the temperature inside the pot to near the target temperature. When the temperature inside the pot reaches the target temperature, the heating stage ends and enters the constant temperature stage; during the constant temperature stage, the control unit 100 controls the heating element 11 to work intermittently to control the temperature inside the pot to maintain near the target temperature to heat the food. Since the heating speed of the air fryer 1 is fast and the heating stage is short, the temperature increase of the food at the end of the heating stage is limited, the water loss of the food is small, and the weight change of the entire pot body is small. During the constant temperature stage, the temperature inside the pot is high, the water evaporation of the food is obvious, and the water evaporation of different amounts of food is different. Selecting the target time period in the constant temperature stage can more accurately identify whether the food is in a standard state.

[0053] In one embodiment of the present application, for some air fryers 1 with wind speed adjustment function and heating element 11 power adjustment function, the speed of the fan 12 is different and the power of the heating element 11 is different in different cooking stages during the cooking process, and the speed of the fan 12 and the power of the heating element 11 can directly affect the evaporation rate of water in the food. In order to eliminate the influence of the speed of the fan 12 and the power of the heating element 11 on the water loss rate of different amounts of food, in a preferred embodiment of the present application, the power of the heating element 11 is constant and the speed of the fan 12 is constant within the target time period.

[0054] In another preferred embodiment of the present application, the target time period includes a first time period between the starting moment and the first moment, and the standard threshold includes a first threshold. If the weight loss slope of the pot body in the first time period is greater than or equal to the first threshold, it indicates that the food is in a non-standard state, and the control unit 100 adjusts the standard cooking parameters to obtain the adjusted cooking parameters.

[0055] Specifically, in this embodiment, when the user uses the air fryer 1 to cook food, the food is first placed in the pot of the air fryer 1. After the placement is successful, the user sends a cooking instruction to the control unit 100 through the software or hardware trigger button set on the air fryer 1. After receiving the cooking instruction, the control unit 100 controls the hot air component 10 to work according to the pre-stored standard cooking parameters to cook the food. During the cooking process, the weighing unit 20 feeds back the weight of the pot to the control unit 100 in real time. Afterwards, the control unit 100 monitors the weight reduction of the food according to the weight of the pot fed back by the weighing unit 20, and calculates the weight loss slope in the first time period between the start time and the first time at the first time. Specifically, assuming that at the starting moment the weighing unit 20 feeds back the weight of the pot body as G0, and at the first moment the weighing unit 20 feeds back the weight of the pot body as G1, then at this time the control unit 100 can calculate the weight loss of the food in the pot body in the first time period as G0-G1, and the weight loss slope of the pot body in the first time period is (G0-G1) / t1, wherein t1 is the time difference between the starting moment and the first moment, and then the control unit 100 compares the weight loss slope of the first time period with the first threshold value, if the weight loss slope of the first time period is greater than or equal to the first threshold value, it indicates that the food is in a non-standard state, because the evaporation rate of the water in the food in the first time period is too fast, it is inferred that the amount of food in the pot is small, and at this time the control unit 100 reduces the standard cooking parameters (reduces the heating power or reduces the cooking time, etc.) to obtain the adjusted cooking parameters, and controls the hot air component 10 to adjust the cooking parameters.

[0056] In addition to the first time period, the target time period of this embodiment also has a second time period, and the standard threshold value has a second threshold value in addition to the first threshold value. If the weight loss slope of the first time period is less than the standard threshold value, the control unit 100 controls the hot air component 10 to continue to work according to the standard cooking parameters until the second moment, and calculates the weight loss slope of the pot body in the second time period between the first moment and the second moment. The control unit 100 compares the weight loss slope of the second time period with the second threshold value. If the weight loss slope of the second time period is greater than or equal to the second threshold value, it indicates that the food is in a standard state, and the control unit 100 controls the hot air component 10 to continue to work according to the standard cooking parameters until the cooking is completed; if the weight loss slope of the second time period is less than the second threshold value, it indicates that the food is in a non-standard state, and the control unit 100 increases the standard cooking parameters (increases the power of the heating element 11 or extends the cooking time, etc.) to obtain the adjusted cooking parameters, and controls the hot air component 10 to work according to the adjusted cooking parameters. Specifically, if the comparison result shows that the weight loss slope of the pot body in the first time period is less than the first threshold value, the control unit 100 controls the air fryer 1 to continue to cook the food according to the standard cooking parameters until the second moment. Then the weighing unit 20 feeds back the weight G2 of the pot body and the inside of the pot body to the control unit 100 at the second moment. Then the control unit 100 can calculate the weight loss slope of the pot body in the second time period t2 (G1-G2) / t2; wherein t2 is the time difference between the first moment and the second moment. Assuming that the first moment is 60s after the start of cooking and the second moment is 130s after the start of cooking, t2 is 70s. After the calculation is successful, the weight loss slope of the pot body in the second time period is compared with the second threshold; if the comparison result shows that the weight loss slope of the pot body in the second time period is greater than or equal to the second threshold, it indicates that the amount of food is moderate and the food is in a standard state; if the comparison result shows that the weight loss slope of the pot body in the second time period is less than the second threshold, it indicates that the amount of food placed is large and the food is in a non-standard state, then the control unit 100 increases the standard cooking parameters and continues to work according to the adjusted cooking parameters.

[0057] In one embodiment, the air fryer 1 further includes a display unit; after executing the above step S240 and obtaining the adjusted cooking parameters, the control unit 100 further executes the following step S250: displaying the adjusted cooking parameters through the display unit.

[0058] In this embodiment, after obtaining the adjusted cooking parameter, the control unit 100 controls the display unit to display the adjusted cooking parameter. In this way, the user can observe the specific value of the adjusted cooking parameter through the display unit.

[0059] In another embodiment of the present application, after the control unit 100 performs the above step S240 and determines the cooking parameters of the air fryer 1 for the food, it controls the air fryer 1 to cook the food according to the determined cooking parameters. Within the first time range before the end of cooking, the control unit 100 can calculate the weight loss slope of the pot body of the air fryer 1 within the unit time, and after the calculation is successful, the weight loss slope of the food within the unit time is compared with the preset third threshold, and then determine whether the air fryer 1 ends the cooking operation according to the comparison result. Specifically, the unit time is v seconds, and the control unit 100 can calculate the weight loss slope of the pot body every v seconds and compare it with the third threshold; if the comparison result shows that the weight loss slope of the pot body within the unit time is less than or equal to the third threshold, it indicates that the maturity of the food has reached the standard, and the air fryer 1 is controlled to end the cooking operation; if the comparison result shows that the weight loss slope of the pot body per unit time is greater than the third threshold, the air fryer 1 is controlled to continue cooking the food, and this process is repeated until the weight loss slope of the pot body per unit time is less than or equal to the third threshold.

[0060] In a preferred implementation of this embodiment, after step S240, the control unit 100 controls the hot air assembly 10 to adjust the cooking parameters until the cooking is finished. If the control unit 100 has not detected that the weight loss slope is less than or equal to the third threshold, when the remaining cooking time is detected to be 0, the air fryer 1 is automatically controlled to end the cooking operation.

[0061] In another preferred implementation of this embodiment, within the first time period before the end of cooking, if the weight loss of the pot body per unit time period is greater than the third threshold and less than or equal to the fourth threshold, the fan 12 is controlled to reduce the rotation speed.

[0062] It can be understood that the preferred value of the first duration is 2 minutes to 5 minutes, and the preferred value of the unit duration is 2 seconds to 10 seconds.

[0063] In this embodiment, the control unit 100 stores the first threshold, the second threshold, the third threshold and the fourth threshold corresponding to each type of food. After receiving the cooking instruction, the control unit 100 can determine the type of food currently placed in the air fryer 1 according to the cooking instruction, and then determine the first threshold, the second threshold, the third threshold and the fourth threshold according to the type of food.

[0064] Through the above measures, a corresponding threshold is set for each type of food, ensuring that the control unit 100 can determine the weight of the food placed in the air fryer 1, and determine whether the food is cooked.
