Description

Technical Field

[0001] The present invention relates to the technical field of cooking control, and in particular to a cooking device and a control method, device and readable storage medium thereof. Background Art

[0002] Cooking equipment with a stirring function, such as a blender, can achieve the mixing and crushing of ingredients.

[0003] However, the blender will produce noise when crushing or stirring. Usually, the decibel of the noise can reach 70 decibels to 90 decibels, or even higher.

[0004] Normally, the noise that a person can receive for a long time is below 60 decibels. Obviously, the above noise will make the user feel uncomfortable and affect the user's rest. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, a first aspect of the present invention is to provide a control method for a cooking device.

[0007] A second aspect of the present invention provides a control device for a cooking device.

[0008] A third aspect of the present invention is to provide another control device for a cooking device.

[0009] A fourth aspect of the present invention provides a readable storage medium.

[0010] A fifth aspect of the present invention provides a cooking device.

[0011] A sixth aspect of the present invention is to provide another cooking device.

[0012] In view of this, according to a first aspect of the present invention, the present invention provides a control method for a cooking device, the cooking device comprising a cooking cavity, a motor and a stirring member, the cooking cavity being used to accommodate food, the motor being used to drive the stirring member to rotate in the cooking cavity, the control method comprising: when a function menu is selected, obtaining an operating current value when the motor operates at a preset stirring gear; determining the hardness of the food according to the operating current value; determining a target gear and a target duration according to the hardness of the food; and controlling the motor to operate at a stirring gear lower than or equal to the target gear until the stirring duration reaches the target duration.

[0013] The technical solution of the present application proposes a control method for a cooking device. By running the above control method, the stirring element in the cooking device can be controlled, thereby achieving stirring and / or crushing of the food.

[0014] In some technical solutions, the target gear and target duration suitable for the cooking device to run are optionally determined according to the hardness of the food, so that the cooking device runs at the target gear or runs at a gear lower than the target gear, thereby achieving the stirring and / or crushing of the food. In this process, by matching different target gears and target durations for different food hardnesses, the running gear of the motor is lowered while ensuring the stirring effect or crushing effect, thereby reducing the noise generated by the cooking device during the stirring and / or crushing process, and improving the user experience.

[0015] In some technical solutions, optionally, after selecting the function menu, the motor is controlled to run at a preset stirring gear, so as to evaluate the hardness of the food by collecting the running current value when the motor runs at the preset stirring gear. In this process, the hardness of the food in the cooking cavity can be detected without the user manually selecting the hardness of the food, thereby improving the credibility of the hardness of the food.

[0016] In addition, the above-mentioned detection of the hardness of the food is performed after the user selects the function menu. Therefore, for the user, the above-mentioned detection can be combined with the stirring or crushing of the food, and the automatic detection of the hardness of the food is realized without affecting the user's use. In this process, no further participation of the user is required, which reduces the impact of user participation on the user experience of the cooking device.

[0017] In some technical solutions, optionally, the function menu can be understood to be a stirring function, a crushing function, or a cooking menu, such as cooking soy milk, rice paste, multi-grain porridge, etc.

[0018] In some technical solutions, the preset stirring gear can be a gear corresponding to the noise that the user can receive for a long time when the cooking device is running. The specific gear is selected according to actual use needs and will not be described in detail here.

[0019] In some technical solutions, optionally, in order to ensure the accuracy of the detected hardness of the food, the above-mentioned operating current value may be an average value of the operating current over a period of time.

[0020] Specifically, if the motor is controlled to run at a preset stirring gear for 30 seconds, the average value of the running current of the motor within 30 seconds is recorded.

[0021] In some technical solutions, optionally, when the motor starts running, timing is started, and when the timing duration reaches a target duration, the motor is controlled to stop running.

[0022] In addition, the control method of the cooking device proposed in this application also has the following additional technical features.

[0023] In some technical schemes, optionally, the hardness of the food is determined according to the operating current value, specifically including: when the operating current value is greater than or equal to the first current threshold, the food hardness is the first hardness; when the operating current value is greater than or equal to the second current threshold and less than the first current threshold, the food hardness is the second hardness; when the operating current value is greater than or equal to the third current threshold and less than the second current threshold, the food hardness is the third hardness; when the operating current value is less than the third current threshold, the food hardness is the fourth hardness; wherein the first hardness, the second hardness, the third hardness and the fourth hardness decrease in sequence.

[0024] In this technical solution, the first current threshold, the second current threshold and the third current threshold are preset, so that after the operating current value is determined, the operating current value can be compared with them, thereby knowing the size of the operating current value.

[0025] Among them, the first current threshold, the second current threshold and the third current threshold are divided into four value range levels, each value range corresponds to a food hardness, and the hardness of the food in the cooking cavity can be known by comparing the operating current value with the above value range.

[0026] Specifically, when the harder the food is, the greater the motor load is, and correspondingly, the greater the operating current value is. Therefore, the hardness of the food can be measured based on the above principle.

[0027] In some technical schemes, optionally, the number of set current thresholds can be selected according to actual usage needs, such as setting only the first current threshold and the second current threshold, or, on the basis of the first current threshold, the second current threshold and the third current threshold, adding a fourth current threshold or a fifth current threshold, so as to refine the hardness of the food and thereby improve the accuracy of cooking control.

[0028] In some technical schemes, optionally, the determination of the hardness of the food can be implemented based on the following logic. Specifically, the operating current value is compared with the first current threshold. If the operating current value is greater than or equal to the first current threshold, the food hardness selects the first hardness. If the operating current value is less than the first current threshold, the operating current value is compared with the second current threshold. If the operating current value is greater than or equal to the second current threshold, the food hardness is the second hardness. If the operating current value is less than the second current threshold, the operating current value is compared with the third current threshold. If the operating current value is greater than or equal to the third current threshold, the food hardness is the third hardness. If the operating current value is less than the third current threshold, the food hardness is the fourth hardness.

[0029] In any of the above technical solutions, the value of the first current threshold is greater than or equal to 2.5A; the value of the second current threshold is greater than or equal to 1.5A and less than 2.5A; the value of the third current threshold is greater than 1A and less than 1.5A.

[0030] In any of the above technical solutions, the function menu is associated with a default stirring time, and the target gear and target time are determined according to the hardness of the food, specifically including: when the hardness of the food is the first hardness, the target gear is the first gear, and the target time is the sum of the default stirring time and the first time; when the hardness of the food is the second hardness, the target gear is the second gear, and the target time is the sum of the default stirring time and the second time; when the hardness of the food is the third hardness, the target gear is the third gear, and the target time is the sum of the default stirring time and the third time; when the hardness of the food is the fourth hardness, the target gear is the fourth gear, and the target time is the default stirring time; wherein, the first gear, the second gear, the third gear and the fourth gear increase in sequence.

[0031] In this technical solution, the default stirring time can be understood as the time required for the motor to drive the stirring element to rotate when the cooking device executes a function menu.

[0032] In some technical solutions, optionally, the smaller the hardness of the food, the smaller the sound generated when the motor drives the stirring element to rotate. Based on this, the gear corresponding to the noise that the user can receive for a longer time is determined according to the hardness of the food, so as to reduce the impact of the noise generated by the operation of the cooking equipment on the user.

[0033] By selecting a larger target gear, the ingredients can be stirred at a larger stirring gear as much as possible, thereby ensuring the stirring effect and shortening the stirring time, thereby shortening the cooking time and improving the user's cooking experience.

[0034] In addition, based on the default stirring time obtained, the stirring time that needs to be compensated on the basis of the default stirring time when the stirring gear is lowered is determined according to the hardness of the food, so as to ensure the stirring effect when the stirring gear is lowered.

[0035] Specifically, the stirring time required to be compensated based on the default stirring time is determined according to the hardness of the food, that is, the first time, the second time, and the third time mentioned above, so as to achieve refined control.

[0036] In some technical solutions, optionally, the target gear can be selected from the first gear, the second gear, the third gear and the fourth gear. When the number of gears of the motor is less than 4 or more than 4, the selection of the above target gear can be changed according to actual usage needs, which will not be repeated here.

[0037] In some technical schemes, optionally, when the target gear is selected differently, the motor speed is different. Based on this, the gears selected by the target gear increase in sequence, which can be understood as the motor speed corresponding to the first gear, the motor speed corresponding to the second gear, the motor speed corresponding to the third gear, and the motor speed corresponding to the fourth gear increase in sequence.

[0038] Specifically, for example, the gears of the motor include 0, 1, 2, 3, 4, 5, 6, 7, 8, H, a total of ten gears. The first gear may be 6 gear, the second gear may be 7 gear, the third gear may be 8 gear, and the fourth gear may be H gear.

[0039] In some technical solutions, optionally, the function menu can be a parameter pre-set in the cooking device before the cooking device leaves the factory. Based on this, the default stirring time is bound to the function menu and is also a parameter pre-set in the cooking device.

[0040] In some technical solutions, optionally, the function menu may be a menu set when the user interacts directly or indirectly with the cooking device. Based on this, the default stirring time may be a parameter entered into the cooking device by the user.

[0041] In any of the above technical solutions, the value of the first duration is between 15 minutes and 30 minutes; the value of the second duration is between 5 minutes and 10 minutes; and the value of the third duration is between 5 minutes and 10 minutes.

[0042] In this technical solution, different values ​​of the first duration, the second duration and the third duration can be selected according to the parameters of the motor, such as the rotation speed.

[0043] In any of the above technical solutions, it also includes: obtaining the activation status of the reservation function; when the reservation function is not enabled, executing the step of determining the hardness of the food according to the operating current value; when the reservation function is enabled, obtaining the reservation duration; determining the fourth duration according to the reservation duration; controlling the motor to operate at a stirring gear lower than or equal to the preset gear until the fifth duration; wherein the fifth duration is the sum of the default stirring time and the fourth time.

[0044] In this technical solution, after the user selects the function menu, he can also choose whether to turn on the reservation function according to actual needs. When the user uses the reservation function, the cooking device can implement reservation control and complete cooking at the time specified by the user.

[0045] By obtaining the enabled status of the reservation function, the stirring gear and stirring time of the motor can be adjusted. In this process, if the reservation control can be realized, the noise generated by the stirring of the stirring element can be controlled, so that the cooking device can run at the gear corresponding to the noise that the user can receive for a longer time, thereby improving the user experience of the cooking device.

[0046] In some technical solutions, optionally, when the reservation function is activated, it can be understood that the reservation function is turned on. Conversely, when the reservation function is not activated, it can be understood that the reservation function is turned off. The user can turn the reservation function on and off through the control panel of the cooking device.

[0047] In the above technical solution, the reservation duration can be understood as the duration from the time the function menu is selected to the target time input by the user, which can be determined according to the actual usage needs of the user and will not be elaborated here.

[0048] For example, the function menu is selected at 08:00 on the same day, and the target time input by the user is 10:00 on the same day, then the reservation duration is the duration between 10:00 and 08:00, that is, 2 hours.

[0049] In some technical solutions, optionally, the fourth time duration is determined based on the reservation time duration, so that the reservation time duration can be referred to during the determination of the fourth time duration to avoid affecting the activation of the reservation function due to the fourth time duration being too long, thereby affecting the cooking control logic.

[0050] In some technical solutions, optionally, the fourth time duration is used as a compensation time duration for stirring of the stirring member, so that the stirring member prolongs the stirring time duration when the stirring gear is lowered, thereby ensuring the stirring effect.

[0051] In some technical solutions, the reservation control of the cooking device can be optionally combined with the noise reduction control, thereby reducing the noise generated by the operation of the cooking device without affecting the user's usage logic, reducing the impact of the noise on the user, and improving the user experience of the cooking device.

[0052] In addition, in some technical solutions, it is optional to achieve continuous stirring or continuous crushing of ingredients, eliminating the impact of noise reduction on the cooking control logic and reducing the chance of users mistakenly believing that there is an error in the cooking control due to changes in the cooking control logic.

[0053] In any of the above technical solutions, the ratio of the fourth duration to the scheduled duration is between 0.1 and 0.15.

[0054] In any of the above technical solutions, the motor is controlled to operate at a stirring gear lower than or equal to the preset gear until the fifth time period, specifically including: obtaining the working time required for the cooking equipment to run the function menu; determining the sixth time period based on the fourth time period, the working time and the reservation time period; when the reservation timing reaches the sixth time period, executing the function menu to control the motor to operate at a stirring gear lower than or equal to the preset gear until the fifth time period.

[0055] In this technical solution, control is achieved by controlling the stirring element to start executing the function menu in advance. During this process, the control logic of the function menu can remain unchanged, reducing the chance of users mistakenly believing that an error has occurred in the cooking control due to changes in the cooking control logic.

[0056] In addition, in some technical solutions, optionally, the noise generated by the cooking device during operation can be reduced without changing the reservation duration, thereby ensuring that the cooking device can complete cooking at the target time selected by the user.

[0057] In some technical solutions, optionally, when the function menu only includes stirring or crushing, the working time is the default stirring time, then when the scheduled timing reaches the sixth time, stirring or crushing starts until the fifth time.

[0058] In some technical solutions, optionally, in addition to stirring or crushing, the function menu also includes other stages, where the other stages include, for example, a heating stage, and the working time includes a heating time and a default stirring time. When the scheduled timing reaches the sixth time, heating begins until the cumulative heating time reaches the heating time. And after the cumulative heating time reaches the heating time, stirring or crushing begins until the fifth time.

[0059] According to a second aspect of the present invention, there is provided a control device for a cooking device, the cooking device comprising a cooking cavity, a motor and a stirring member, the cooking cavity being used to contain food, the motor being used to drive the stirring member to rotate in the cooking cavity, the control device comprising: an acquisition unit, for acquiring, when a function menu is selected, an operating current value of the motor when operating at a preset stirring gear; a determination unit, for determining the hardness of the food according to the operating current value; a processing unit, for determining a target gear and a target duration according to the hardness of the food; and a control unit, for controlling the motor to operate at a stirring gear lower than or equal to the target gear until the stirring duration reaches the target duration.

[0060] The technical solution of the present application proposes a control device for a cooking device, which can realize the control of a stirring element in the cooking device, and further realize the stirring and / or crushing processing of food materials.

[0061] In some technical solutions, the target gear and target duration suitable for the cooking device to run are optionally determined according to the hardness of the food, so that the cooking device runs at the target gear or runs at a gear lower than the target gear, thereby achieving the stirring and / or crushing of the food. In this process, by matching different target gears and target durations for different food hardnesses, the running gear of the motor is lowered while ensuring the stirring effect or crushing effect, thereby reducing the noise generated by the cooking device during the stirring and / or crushing process, and improving the user experience.

DETAILED DESCRIPTION

[0142] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0143] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0144] In one embodiment of the present application, Figure 1 As shown, a control method for a cooking device is provided. The cooking device includes a cooking cavity, a motor and a stirring member. The cooking cavity is used to hold food. The motor is used to drive the stirring member to rotate in the cooking cavity. The control method includes:

[0145] Step 102, when the function menu is selected, obtaining the running current value of the motor when it runs according to the preset stirring gear;

[0146] Step 104, determining the hardness of the food according to the operating current value;

[0147] Step 106, determining a target gear position and a target duration according to the hardness of the food;

[0148] Step 108, controlling the motor to operate at a stirring gear lower than or equal to the target gear until the stirring time reaches the target time.

[0149] The embodiment of the present application proposes a control method for a cooking device. By running the above control method, the stirring element in the cooking device can be controlled, thereby achieving stirring and / or crushing processing of ingredients.

[0150] In some embodiments, the target gear and target duration for the cooking device to run are optionally determined according to the hardness of the food, so that the cooking device runs at the target gear or runs at a gear lower than the target gear, thereby achieving the stirring and / or crushing of the food. In this process, by matching different target gears and target durations for different food hardnesses, the running gear of the motor is lowered while ensuring the stirring or crushing effect, thereby reducing the noise generated by the cooking device during the stirring and / or crushing process, and improving the user experience.

[0151] In some embodiments, optionally, after selecting the function menu, the motor is controlled to run at a preset stirring gear, so as to evaluate the hardness of the food by collecting the running current value when the motor runs at the preset stirring gear. In this process, the hardness of the food in the cooking cavity can be detected without the user manually selecting the hardness of the food, thereby improving the credibility of the hardness of the food.

[0152] In addition, the above-mentioned detection of the hardness of the food is performed after the user selects the function menu. Therefore, for the user, the above-mentioned detection can be combined with the stirring or crushing of the food, and the automatic detection of the hardness of the food is realized without affecting the user's use. In this process, no further participation of the user is required, which reduces the impact of user participation on the user experience of the cooking device.

[0153] In some embodiments, optionally, the function menu can be understood to be a stirring function, a crushing function, or a cooking menu, such as cooking soy milk, rice paste, multi-grain porridge, etc.

[0154] In some embodiments, the preset stirring gear can be a gear corresponding to the noise that the user can receive for a long time when the cooking device is running. The specific gear is selected according to actual use needs and will not be described in detail here.

[0155] In some embodiments, optionally, in order to ensure the accuracy of the detected hardness of the food, the operating current value may be an average value of the operating current over a period of time.

[0156] Specifically, if the motor is controlled to run at a preset stirring gear for 30 seconds, the average value of the running current of the motor within 30 seconds is recorded.

[0157] In some embodiments, optionally, when the motor starts running, timing is started, and when the timing duration reaches a target duration, the motor is controlled to stop running.

[0158] In some embodiments, optionally, the hardness of the food is determined according to the operating current value, specifically including: when the operating current value is greater than or equal to a first current threshold, the food hardness is a first hardness; when the operating current value is greater than or equal to a second current threshold and less than the first current threshold, the food hardness is a second hardness; when the operating current value is greater than or equal to a third current threshold and less than the second current threshold, the food hardness is a third hardness; when the operating current value is less than the third current threshold, the food hardness is a fourth hardness; wherein the first hardness, the second hardness, the third hardness and the fourth hardness decrease in sequence.

[0159] In this embodiment, the first current threshold, the second current threshold and the third current threshold are preset so that after the operating current value is determined, the operating current value can be compared with them to know the magnitude of the operating current value.

[0160] Among them, the first current threshold, the second current threshold and the third current threshold are divided into four value range levels, each value range corresponds to a food hardness, and the hardness of the food in the cooking cavity can be known by comparing the operating current value with the above value range.

[0161] Specifically, when the harder the food is, the greater the motor load is, and correspondingly, the greater the operating current value is. Therefore, the hardness of the food can be measured based on the above principle.

[0162] In some embodiments, optionally, the number of current thresholds to be set can be selected according to actual usage needs, such as only setting the first current threshold and the second current threshold, or, on the basis of the first current threshold, the second current threshold and the third current threshold, adding a fourth current threshold or a fifth current threshold, so as to refine the hardness of the food and thereby improve the accuracy of cooking control.

[0163] In some embodiments, optionally, the determination of the food hardness can be achieved based on the following logic. Specifically, the operating current value is compared with a first current threshold. If the operating current value is greater than or equal to the first current threshold, the food hardness selects the first hardness. If the operating current value is less than the first current threshold, the operating current value is compared with a second current threshold. If the operating current value is greater than or equal to the second current threshold, the food hardness is the second hardness. If the operating current value is less than the second current threshold, the operating current value is compared with a third current threshold. If the operating current value is greater than or equal to the third current threshold, the food hardness is the third hardness. If the operating current value is less than the third current threshold, the food hardness is the fourth hardness.

[0164] In any of the above embodiments, the value of the first current threshold is greater than or equal to 2.5A; the value of the second current threshold is greater than or equal to 1.5A and less than 2.5A; the value of the third current threshold is greater than 1A and less than 1.5A.

[0165] In any of the above embodiments, the function menu is associated with a default stirring time, and the target gear and target time are determined according to the hardness of the food, specifically including: when the hardness of the food is the first hardness, the target gear is the first gear, and the target time is the sum of the default stirring time and the first time; when the hardness of the food is the second hardness, the target gear is the second gear, and the target time is the sum of the default stirring time and the second time; when the hardness of the food is the third hardness, the target gear is the third gear, and the target time is the sum of the default stirring time and the third time; when the hardness of the food is the fourth hardness, the target gear is the fourth gear, and the target time is the default stirring time; wherein, the first gear, the second gear, the third gear and the fourth gear increase in sequence.

[0166] In this embodiment, the default stirring time can be understood as the time required for the motor to drive the stirring element to rotate when the cooking device executes the function menu.

[0167] In some embodiments, optionally, the smaller the hardness of the food, the smaller the sound generated when the motor drives the stirring element to rotate. Based on this, the gear corresponding to the noise that the user can receive for a longer time is determined according to the hardness of the food, so as to reduce the impact of the noise generated by the operation of the cooking equipment on the user.

[0168] By selecting a larger target gear, the ingredients can be stirred at a larger stirring gear as much as possible, thereby ensuring the stirring effect and shortening the stirring time, thereby shortening the cooking time and improving the user's cooking experience.

[0169] In addition, based on the default stirring time obtained, the stirring time that needs to be compensated on the basis of the default stirring time when the stirring gear is lowered is determined according to the hardness of the food, so as to ensure the stirring effect when the stirring gear is lowered.

[0170] Specifically, the stirring time required to be compensated based on the default stirring time is determined according to the hardness of the food, that is, the first time, the second time, and the third time mentioned above, so as to achieve refined control.

[0171] In some embodiments, optionally, the target gear can be selected from the first gear, the second gear, the third gear and the fourth gear. When the number of gears of the motor is less than 4 or more than 4, the selection of the above target gear can be changed according to actual usage needs, which will not be repeated here.

[0172] In some embodiments, optionally, when the target gear is selected differently, the motor speed is different. Based on this, the gears selected by the target gear increase in sequence, which can be understood as the motor speed corresponding to the first gear, the motor speed corresponding to the second gear, the motor speed corresponding to the third gear, and the motor speed corresponding to the fourth gear increase in sequence.

[0173] Specifically, for example, the gears of the motor include 0, 1, 2, 3, 4, 5, 6, 7, 8, H, a total of ten gears. The first gear may be 6 gear, the second gear may be 7 gear, the third gear may be 8 gear, and the fourth gear may be H gear.

[0174] In some embodiments, optionally, the function menu can be a parameter pre-set in the cooking device before the cooking device leaves the factory. Based on this, the default stirring time is bound to the function menu and is also a parameter pre-set in the cooking device.

[0175] In some embodiments, optionally, the function menu may be a menu set when the user interacts directly or indirectly with the cooking device, based on which the default stirring time may be a parameter entered into the cooking device by the user.

[0176] In any of the above embodiments, the value of the first duration is between 15 minutes and 30 minutes; the value of the second duration is between 5 minutes and 10 minutes; and the value of the third duration is between 5 minutes and 10 minutes.

[0177] In this embodiment, different values ​​of the first duration, the second duration and the third duration can be selected according to parameters of the motor, such as the rotation speed.

[0178] In any of the above embodiments, it also includes: obtaining the activation status of the reservation function; when the reservation function is not enabled, executing the step of determining the hardness of the food according to the operating current value; when the reservation function is enabled, obtaining the reservation duration; determining the fourth duration according to the reservation duration; controlling the motor to operate at a stirring gear lower than or equal to the preset gear until the fifth duration; wherein the fifth duration is the sum of the default stirring duration and the fourth duration.

[0179] In this embodiment, after the user selects the function menu, he or she can also choose whether to turn on the reservation function according to actual usage needs. When the user uses the reservation function, the cooking device can implement reservation control and complete cooking at the time specified by the user.

[0180] By obtaining the enabled status of the reservation function, the stirring gear and stirring time of the motor can be adjusted. In this process, if the reservation control can be realized, the noise generated by the stirring of the stirring element can be controlled, so that the cooking device can run at the gear corresponding to the noise that the user can receive for a longer time, thereby improving the user experience of the cooking device.

[0181] In some embodiments, optionally, when the reservation function is activated, it can be understood that the reservation function is turned on. Conversely, when the reservation function is not activated, it can be understood that the reservation function is turned off. The user can turn the reservation function on and off through the control panel of the cooking device.

[0182] In the above embodiment, the reservation duration can be understood as the duration from the time when the function menu is selected to the target time input by the user, which can be determined according to the actual usage needs of the user and will not be elaborated here.

[0183] For example, the function menu is selected at 08:00 on the same day, and the target time input by the user is 10:00 on the same day, then the reservation duration is the duration between 10:00 and 08:00, that is, 2 hours.

[0184] In some embodiments, optionally, the fourth duration is determined based on the reservation duration, so that the reservation duration can be referred to during the determination of the fourth duration to avoid affecting the activation of the reservation function due to the fourth duration being too long, thereby affecting the cooking control logic.

[0185] In some embodiments, optionally, the fourth time duration is used as a compensation time duration for stirring of the stirring member, so that the stirring member prolongs the stirring time duration when the stirring gear is lowered, thereby ensuring the stirring effect.

[0186] In some embodiments, the reservation control of the cooking device can be optionally combined with the noise reduction control, thereby reducing the noise generated by the operation of the cooking device without affecting the user's usage logic, reducing the impact of the noise on the user, and improving the user experience of the cooking device.

[0187] In addition, in some embodiments, continuous stirring or continuous crushing of ingredients can be optionally achieved, eliminating the impact of noise reduction on the cooking control logic and reducing the chance of users mistakenly believing that an error has occurred in the cooking control due to changes in the cooking control logic.

[0188] In any of the above embodiments, the ratio of the fourth duration to the scheduled duration is between 0.1 and 0.15.

[0189] In any of the above embodiments, controlling the motor to operate at a stirring gear lower than or equal to the preset gear until the fifth time period specifically includes: obtaining the working time required for the cooking device to run the function menu; determining the sixth time period based on the fourth time period, the working time and the reservation time period; when the reservation timing reaches the sixth time period, executing the function menu to control the motor to operate at a stirring gear lower than or equal to the preset gear until the fifth time period.

[0190] In this embodiment, control is achieved by controlling the stirring element to start executing the function menu in advance. During this process, the control logic of the function menu can remain unchanged, thereby reducing the chance that the user will mistakenly believe that an error has occurred in the cooking control due to a change in the cooking control logic.

[0191] Furthermore, in some embodiments, it is possible to optionally reduce the noise generated by the cooking device during operation without changing the reservation duration, thereby ensuring that the cooking device can complete cooking at the target time selected by the user.

[0192] In some embodiments, optionally, when the function menu only includes stirring or crushing, the working time is the default stirring time, then when the scheduled timing reaches the sixth time, stirring or crushing begins until the fifth time.

[0193] In some embodiments, optionally, in addition to stirring or crushing, the function menu also includes other stages, where the other stages include, for example, a heating stage, and the working time includes a heating time and a default stirring time. When the scheduled timing reaches the sixth time, heating begins until the cumulative heating time reaches the heating time. And after the cumulative heating time reaches the heating time, stirring or crushing begins until the fifth time.

[0194] In some embodiments, optionally, Figure 2 As shown, the control method of the cooking device includes:

[0195] Step 202, power on and enter standby mode;

[0196] Step 204, select the function menu to start;

[0197] Step 206, the motor beats at level 5 for 3 seconds;

[0198] Step 208, sampling the stirring current Im;

[0199] Step 210, whether to make an appointment, if the judgment result is yes, execute step 212, if the judgment result is no, execute step 214,

[0200] Step 212, make an appointment to enter work Tc in advance;

[0201] Step 214, the cooking enters the stirring stage;

[0202] Step 216, the cooking enters the stirring stage;

[0203] Step 218, the highest stirring gear is not higher than gear 5 and the stirring time is +Tc;

[0204] Step 220, if Im≥Ia, when the judgment result is yes, execute Step 222, and when the judgment result is no, execute Step 224;

[0205] Step 222, the highest stirring gear is not higher than gear 6 and the stirring time is +Ta;

[0206] Step 224, if Im≥Ib, when the judgment result is yes, execute Step 226, and when the judgment result is no, execute Step 228;

[0207] Step 226, the highest stirring gear is not higher than gear 7 and the stirring time is +Tb;

[0208] Step 228, if Im≥Ic, when the judgment result is yes, execute Step 230, and when the judgment result is no, execute Step 232;

[0209] Step 230, the highest stirring gear is not higher than gear 8 and the stirring time is +Tb;

[0210] Step 232, the highest stirring gear is not higher than gear H and the stirring time.

[0211] Wherein, Ia corresponds to the first current threshold in this application, Ib corresponds to the second current threshold in this application, Ic corresponds to the third current threshold in this application, Ta corresponds to the first duration in this application. When the second duration and the third duration have the same value, the second duration and the third duration are represented by Tb.

[0212] In this embodiment, the hardness of the food ingredients is judged by the magnitude of the current, and the hardness is divided into grades A, B, C, and D. When 30 seconds before the start of stirring, the hardness A, B, C, D is defined by the magnitude of the stirring current. When the current Im≥Ia (2.5A < Ia), the hardness is A. When the current Im≥Ib (1.5A < Ib < 2.5A), the hardness is B. When the current Im≥Ic (1A < Ic < 1.5A), the hardness is C. The remaining judgment interval is hardness D. Through the food ingredient grade, the stirring gear and the stirring power are determined. The cooking scenario mainly judges whether the wall breaker is in the pre-set recipe. By lengthening the stirring, the stirring gear and the power are further optimized, so as to adopt a reasonable motor stirring control logic when the personnel are resting, and reduce the stirring noise of the cooking food ingredients.

[0213] By entering the menu function and starting, it stirs for 3S in fixed position while detecting the stirring current Im and enters the working state. When the function menu is in the reservation mode, it can enter the function cooking in advance by a certain time Tc, extend the stirring time, reduce the applied power, and reduce the stirring noise to achieve a good stirring effect. When directly entering the menu function is selected, the hardness can be classified into grades A, B, C, and D based on Im. Different hardness grades adopt different stirring powers plus a certain stirring compensation time to reduce the stirring noise and make the ingredients delicate.

[0214] After judging different hardness grades, adjust the stirring gear and compensate the stirring time according to different grades. When the hardness is grade A, the stirring gear is reduced to gear 6, and the stirring time is increased by Ta (15 min < Ta < 30 min) on the original basis. When the hardness is grade B, the stirring gear is reduced to gear 7, and the stirring time is increased by Tb (5 min < Tb < 10 min) on the original basis. When the hardness is grade C, the stirring gear is gear 8, and the stirring time is increased by Tb (5 min < Tb < 10 min) on the original basis. When the hardness is grade D, the stirring gear is gear H and the time remains unchanged.

[0215] In some embodiments, optionally, as Figure 3 shown, the present invention provides a control device 300 for a cooking device. The cooking device includes a cooking cavity, a motor, and a stirring member. The cooking cavity is used to accommodate ingredients, the motor is used to drive the stirring member to rotate in the cooking cavity. The control device includes: an acquisition unit 302, configured to acquire the operating current value when the motor operates at a preset stirring gear when the function menu is selected; a determination unit 304, configured to determine the ingredient hardness according to the operating current value; a processing unit 306, configured to determine a target gear and a target duration according to the ingredient hardness; and a control unit 308, configured to control the motor to operate at a stirring gear lower than or equal to the target gear until the stirring duration reaches the target duration.

[0216] The embodiment of the present application proposes a control device 300 for a cooking device, which can realize the control of the stirring member in the cooking device, and further realize the stirring process and / or crushing process of the ingredients.

[0217] In some embodiments, optionally, determine the target gear and the target duration suitable for the operation of the cooking device according to the ingredient hardness, so that the cooking device operates at the target gear or at a gear lower than the target gear, thereby achieving the stirring process and / or crushing process of the ingredients. During this process, by matching different target gears and target durations for different ingredient hardnesses, while ensuring the stirring effect or crushing effect, the operating gear of the motor is lowered, thereby reducing the noise generated by the cooking device during the stirring process and / or crushing process and improving the user experience.

[0218] In some embodiments, optionally, after selecting the function menu, the motor is controlled to run at a preset stirring gear, so as to evaluate the hardness of the food by collecting the running current value when the motor runs at the preset stirring gear. In this process, the hardness of the food in the cooking cavity can be detected without the user manually selecting the hardness of the food, thereby improving the credibility of the hardness of the food.

[0219] In addition, the above-mentioned detection of the hardness of the food is performed after the user selects the function menu. Therefore, for the user, the above-mentioned detection can be combined with the stirring or crushing of the food, and the automatic detection of the hardness of the food is realized without affecting the user's use. In this process, no further participation of the user is required, which reduces the impact of user participation on the user experience of the cooking device.

[0220] In some embodiments, optionally, the function menu can be understood to be a stirring function, a crushing function, or a cooking menu, such as cooking soy milk, rice paste, multi-grain porridge, etc.

[0221] In some embodiments, the preset stirring gear can be a gear corresponding to the noise that the user can receive for a long time when the cooking device is running. The specific gear is selected according to actual use needs and will not be described in detail here.

[0222] In some embodiments, optionally, in order to ensure the accuracy of the detected hardness of the food, the operating current value may be an average value of the operating current over a period of time.

[0223] Specifically, if the motor is controlled to run at a preset stirring gear for 30 seconds, the average value of the running current of the motor within 30 seconds is recorded.

[0224] In some embodiments, optionally, when the motor starts running, timing is started, and when the timing duration reaches a target duration, the motor is controlled to stop running.

[0225] In addition, the control method of the cooking device proposed in this application also has the following additional technical features.

[0226] In any of the above embodiments, the determination unit 304 is specifically used to: when the operating current value is greater than or equal to the first current threshold, the food hardness is the first hardness; when the operating current value is greater than or equal to the second current threshold and less than the first current threshold, the food hardness is the second hardness; when the operating current value is greater than or equal to the third current threshold and less than the second current threshold, the food hardness is the third hardness; when the operating current value is less than the third current threshold, the food hardness is the fourth hardness; wherein the first hardness, the second hardness, the third hardness and the fourth hardness decrease in sequence.

[0227] In this embodiment, the first current threshold, the second current threshold and the third current threshold are preset so that after the operating current value is determined, the operating current value can be compared with them to know the magnitude of the operating current value.

[0228] Among them, the first current threshold, the second current threshold and the third current threshold are divided into four value range levels, each value range corresponds to a food hardness, and the hardness of the food in the cooking cavity can be known by comparing the operating current value with the above value range.

[0229] Specifically, when the harder the food is, the greater the motor load is, and correspondingly, the greater the operating current value is. Therefore, the hardness of the food can be measured based on the above principle.

[0230] In some embodiments, optionally, the number of current thresholds to be set can be selected according to actual usage needs, such as only setting the first current threshold and the second current threshold, or, on the basis of the first current threshold, the second current threshold and the third current threshold, adding a fourth current threshold or a fifth current threshold, so as to refine the hardness of the food and thereby improve the accuracy of cooking control.

[0231] In some embodiments, optionally, the determination of the food hardness can be achieved based on the following logic. Specifically, the operating current value is compared with a first current threshold. If the operating current value is greater than or equal to the first current threshold, the food hardness selects the first hardness. If the operating current value is less than the first current threshold, the operating current value is compared with a second current threshold. If the operating current value is greater than or equal to the second current threshold, the food hardness is the second hardness. If the operating current value is less than the second current threshold, the operating current value is compared with a third current threshold. If the operating current value is greater than or equal to the third current threshold, the food hardness is the third hardness. If the operating current value is less than the third current threshold, the food hardness is the fourth hardness.

[0232] In any of the above embodiments, the value of the first current threshold is greater than or equal to 2.5A; the value of the second current threshold is greater than or equal to 1.5A and less than 2.5A; the value of the third current threshold is greater than 1A and less than 1.5A.

[0233] In any of the above embodiments, the function menu is associated with a default stirring time, and the processing unit 306 is specifically used for: when the hardness of the food is the first hardness, the target gear is the first gear, and the target time is the sum of the default stirring time and the first time; when the hardness of the food is the second hardness, the target gear is the second gear, and the target time is the sum of the default stirring time and the second time; when the hardness of the food is the third hardness, the target gear is the third gear, and the target time is the sum of the default stirring time and the third time; when the hardness of the food is the fourth hardness, the target gear is the fourth gear, and the target time is the default stirring time; wherein, the first gear, the second gear, the third gear and the fourth gear increase in sequence.

[0234] In this embodiment, the default stirring time can be understood as the time required for the motor to drive the stirring element to rotate when the cooking device executes the function menu.

[0235] In some embodiments, optionally, the smaller the hardness of the food, the smaller the sound generated when the motor drives the stirring element to rotate. Based on this, the gear corresponding to the noise that the user can receive for a longer time is determined according to the hardness of the food, so as to reduce the impact of the noise generated by the operation of the cooking equipment on the user.

[0236] By selecting a larger target gear, the ingredients can be stirred at a larger stirring gear as much as possible, thereby ensuring the stirring effect and shortening the stirring time, thereby shortening the cooking time and improving the user's cooking experience.

[0237] In addition, based on the default stirring time obtained, the stirring time that needs to be compensated on the basis of the default stirring time when the stirring gear is lowered is determined according to the hardness of the food, so as to ensure the stirring effect when the stirring gear is lowered.

[0238] Specifically, the stirring time required to be compensated based on the default stirring time is determined according to the hardness of the food, that is, the first time, the second time, and the third time mentioned above, so as to achieve refined control.

[0239] In some embodiments, optionally, the target gear can be selected from the first gear, the second gear, the third gear and the fourth gear. When the number of gears of the motor is less than 4 or more than 4, the selection of the above target gear can be changed according to actual usage needs, which will not be repeated here.

[0240] In some embodiments, optionally, when the target gear is selected differently, the motor speed is different. Based on this, the gears selected by the target gear increase in sequence, which can be understood as the motor speed corresponding to the first gear, the motor speed corresponding to the second gear, the motor speed corresponding to the third gear, and the motor speed corresponding to the fourth gear increase in sequence.

[0241] Specifically, for example, the gears of the motor include 0, 1, 2, 3, 4, 5, 6, 7, 8, H, a total of ten gears. The first gear may be 6 gear, the second gear may be 7 gear, the third gear may be 8 gear, and the fourth gear may be H gear.

[0242] In some embodiments, optionally, the function menu can be a parameter pre-set in the cooking device before the cooking device leaves the factory. Based on this, the default stirring time is bound to the function menu and is also a parameter pre-set in the cooking device.

[0243] In some embodiments, optionally, the function menu may be a menu set when the user interacts directly or indirectly with the cooking device, based on which the default stirring time may be a parameter entered into the cooking device by the user.

[0244] In any of the above embodiments, the value of the first duration is between 15 minutes and 30 minutes; the value of the second duration is between 5 minutes and 10 minutes; and the value of the third duration is between 5 minutes and 10 minutes.

[0245] In this embodiment, different values ​​of the first duration, the second duration and the third duration can be selected according to parameters of the motor, such as the rotation speed.

[0246] In any of the above embodiments, the control unit 308 is also used to: obtain the activation status of the reservation function; when the reservation function is not enabled, execute the step of determining the hardness of the food according to the operating current value; when the reservation function is enabled, obtain the reservation duration; determine the fourth duration according to the reservation duration; control the motor to operate at a stirring gear lower than or equal to the preset gear until the fifth duration; wherein the fifth duration is the sum of the default stirring duration and the fourth duration.

[0247] In this embodiment, after the user selects the function menu, he or she can also choose whether to turn on the reservation function according to actual usage needs. When the user uses the reservation function, the cooking device can implement reservation control and complete cooking at the time specified by the user.

[0248] By obtaining the enabled status of the reservation function, the stirring gear and stirring time of the motor can be adjusted. In this process, if the reservation control can be realized, the noise generated by the stirring of the stirring element can be controlled, so that the cooking device can run at the gear corresponding to the noise that the user can receive for a longer time, thereby improving the user experience of the cooking device.

[0249] In some embodiments, optionally, when the reservation function is activated, it can be understood that the reservation function is turned on. Conversely, when the reservation function is not enabled, it can be understood that the reservation function is turned off. The user can turn the reservation function on and off through the control panel of the cooking device.

[0250] In the above embodiment, the reservation duration can be understood as the duration from the time when the function menu is selected to the target time input by the user, which can be determined according to the actual usage needs of the user and will not be elaborated here.

[0251] For example, the function menu is selected at 08:00 on the same day, and the target time input by the user is 10:00 on the same day, then the reservation duration is the duration between 10:00 and 08:00, that is, 2 hours.

[0252] In some embodiments, optionally, the fourth duration is determined based on the reservation duration, so that the reservation duration can be referred to during the determination of the fourth duration to avoid affecting the activation of the reservation function due to the fourth duration being too long, thereby affecting the cooking control logic.

[0253] In some embodiments, optionally, the fourth time duration is used as a compensation time duration for stirring of the stirring member, so that the stirring member prolongs the stirring time duration when the stirring gear is lowered, thereby ensuring the stirring effect.

[0254] In some embodiments, the reservation control of the cooking device can be optionally combined with the noise reduction control, thereby reducing the noise generated by the operation of the cooking device without affecting the user's usage logic, reducing the impact of the noise on the user, and improving the user experience of the cooking device.

[0255] In addition, in some embodiments, continuous stirring or continuous crushing of ingredients can be optionally achieved, eliminating the impact of noise reduction on the cooking control logic and reducing the chance of users mistakenly believing that an error has occurred in the cooking control due to changes in the cooking control logic.

[0256] In any of the above embodiments, the ratio of the fourth duration to the scheduled duration is between 0.1 and 0.15.

[0257] In any of the above embodiments, the control unit 308 is specifically used to: obtain the working time required for the cooking equipment to run the function menu; determine the sixth time based on the fourth time, the working time and the reservation time; when the reservation timing reaches the sixth time, execute the function menu to control the motor to run at a stirring gear lower than or equal to the preset gear until the fifth time.

[0258] In this embodiment, control is achieved by controlling the stirring element to start executing the function menu in advance. During this process, the control logic of the function menu can remain unchanged, thereby reducing the chance that the user will mistakenly believe that an error has occurred in the cooking control due to a change in the cooking control logic.

[0259] Furthermore, in some embodiments, it is possible to optionally reduce the noise generated by the cooking device during operation without changing the reservation duration, thereby ensuring that the cooking device can complete cooking at the target time selected by the user.

[0260] In some embodiments, optionally, when the function menu only includes stirring or crushing, the working time is the default stirring time, then when the scheduled timing reaches the sixth time, stirring or crushing begins until the fifth time.

[0261] In some embodiments, optionally, in addition to stirring or crushing, the function menu also includes other stages, where the other stages include, for example, a heating stage, and the working time includes a heating time and a default stirring time. When the scheduled timing reaches the sixth time, heating begins until the cumulative heating time reaches the heating time. And after the cumulative heating time reaches the heating time, stirring or crushing begins until the fifth time.

[0262] In some embodiments, optionally, Figure 4 As shown, the present invention provides another control device 400 for cooking equipment, including a processor 402 and a memory 404. The memory 404 stores programs or instructions that can be run on the processor 402.
