Description

Technical Field

[0001] The present application relates to the technical field of food processors, and more particularly, to a method for making high-fiber slurry. Background Art

[0002] In the prior art, when a food processor processes ingredients into a slurry with a high-fiber texture, it usually uses the non-cutting edge surface or a relatively thick cutting edge of the blade to stir or assist in crushing the ingredients. When the food processor just enters the processing stage and the blade starts to rotate initially, the ingredients to be cut in the processing chamber are usually in large pieces or have a relatively hard texture, and the ingredients are likely to get stuck on the blade, causing problems such as motor stalling or jitter, which may further result in frequent alarms or damage to the food processor. The prior art CN 109363534B discloses a crushing method for a food processor, which processes ingredients by driving a crushing blade to continuously operate in an alternating manner of forward rotation and reverse rotation by a brushless motor. Although this solution can reduce the occurrence of stalling problems, the resulting slurry has a very small particle size and cannot achieve the preparation of a slurry with a high-fiber texture (coarse particles). In addition, after the food processor starts processing, it is difficult for the user to solve the above stalling problem by shaking the cup body or other means; if the user does not detect the stalling in time, the motor is also likely to be damaged due to overheating, or the food processor always requires the user to repeatedly manually adjust the position of the ingredients and then restart the processing. This brings a lot of inconvenience to the user's operation, affects the quality and lifespan of the food processor, and reduces the user's experience. Summary of the Invention

[0003] The purpose of the present application is to provide a method for making high-fiber slurry, which reversely stirs the ingredients with a tool when making the high-fiber slurry, does not alarm temporarily when encountering a stalling problem, attempts to solve the stalling by switching to forward rotation, and automatically resumes reverse rotation after the forward rotation runs normally for a certain period of time. Therefore, the present application has the advantages of improving the intelligence and reliability of the operation of the food processor, and improving the slurry-making efficiency and slurry-making quality.

[0004] The embodiments of the present application are implemented as follows:

[0005] In the first aspect of the embodiments of the present application, a method for making high-fiber slurry is provided. This method is applied to a food processor, which includes a blade and a brushless motor. The brushless motor is configured to drive the blade to rotate forward or backward. When the blade rotates forward, it crushes the ingredients through the first edge, and when the blade rotates backward, it stirs the ingredients through the second edge. The food processor detects the stirring current in real time when the blade rotates; the method for making slurry includes: when making high-fiber slurry, controlling the blade to rotate backward; when the blade rotates backward, if the stirring current reaches a preset current threshold, record an abnormal current problem once; if the cumulative record count of the abnormal current problem is less than a preset count threshold, switch the rotation direction of the blade from backward to forward through the brushless motor; when the blade rotates forward, if the stirring current is always lower than the preset current threshold within a preset duration, switch the rotation direction of the blade from forward to backward through the brushless motor to continue stirring the ingredients.

[0006] In one embodiment, if the cumulative record count of the abnormal current problem is less than a preset count threshold, switching the rotation direction of the blade from backward to forward through the brushless motor includes: determining a first target rotation speed of the blade when it rotates forward based on the initial rotation speed when the blade rotates backward; driving the blade to rotate in the forward direction at the first target rotation speed through the brushless motor.

[0007] In one embodiment, determining a first target rotation speed of the blade when it rotates forward based on the initial rotation speed when the blade rotates backward includes: calculating the first target rotation speed based on the initial rotation speed, and known ingredient information and / or a preset rotation speed adjustment value; the first target rotation speed is not lower than the initial rotation speed.

[0008] In one embodiment, before driving the blade to rotate in the forward direction at the first target rotation speed through the brushless motor, the method for making slurry further includes: when the stirring current reaches the preset current threshold, stopping the rotation of the blade through the brushless motor until the duration of the blade's stop reaches the stationary duration.

[0009] In one embodiment, after switching the rotation direction of the blade from backward to forward through the brushless motor, the method for making slurry further includes: when the blade rotates forward, if the stirring current reaches the preset current threshold within a preset duration, controlling the blade to stop rotating and record an abnormal current problem once; if the cumulative record count of the abnormal current problem is less than a preset count threshold, when the duration of the blade's stop reaches the stationary duration, controlling the blade to continue rotating in the forward direction at a second target rotation speed; the second target rotation speed is greater than the first target rotation speed.

[0010] In one embodiment, after recording an abnormal current problem once, the method for making slurry further includes: if the cumulative record count of the abnormal current problem reaches the preset count threshold, giving an alarm for the abnormal current.

[0011] In one embodiment, after recording the problem of abnormal primary current, the pulping method further includes: based on the cumulative recording times of the current abnormal problem, updating the remaining stirring times of the blade for the reverse direction.

[0012] In one embodiment, after recording the problem of abnormal primary current, the pulping method further includes: if the cumulative recording times of the current abnormal problem do not reach the preset times threshold, determining the rotational speed increment value corresponding to the next rotation of the blade based on the cumulative recording times; the rotational speed increment value increases with the increase of the cumulative recording times.

[0013] In one embodiment, before controlling the blade to reverse, the pulping method further includes: based on the food ingredient type corresponding to the high-fiber slurry, determining the preset current threshold corresponding to the current abnormal problem and / or the preset times threshold corresponding to the current abnormal alarm.

[0014] In one embodiment, when the food processor is making high-fiber slurry, controlling the blade to perform multiple rounds of cyclic stirring in the reverse direction. Before controlling the blade to reverse, the pulping method further includes: based on the known target slurry state, determining the target heating gear and the initial reverse rotation speed corresponding to each round of cyclic stirring.

[0015] The beneficial effects of the present application compared with the prior art are:

[0016] The present application can solve the problems that the existing food processor frequently has stall alarms and cannot automatically resume normal pulping work when making high-fiber slurry. When making high-fiber slurry, the present application uses the reverse rotation of the blade to continuously stir the food ingredients with the second blade to obtain a slurry with a large particle size and a high-fiber texture; when the blade is stalled by large pieces of materials and the brushless motor stirring current is too large for the first time, the present application does not alarm temporarily. After recording the current abnormal problem, the rotation direction of the blade is switched from reverse to forward to enable the blade to quickly leave the stalled area, and the first blade is used to effectively crush and cut the food ingredients to make the materials smaller; after the blade rotates forward, the present application monitors the stirring current based on a preset duration to confirm whether the food processor has solved the stall problem, and automatically resumes the reverse rotation of the blade after the stall problem is solved. Thus, the present application has the advantages of reducing the alarm frequency, automatically resuming the pulping work, improving the pulping efficiency of the food processor, working intelligence and working reliability.

[0017] In addition, when the present application detects that the stirring current is too large and the motor has an abnormal current problem, it controls the blade to stop rotating and maintain for a certain period of time, which can buffer and intermittently stop the brushless motor after current overload, preventing the motor from being damaged due to excessive temperature rise; the present application increases the rotational speed for the blade rotation, which can improve the cutting ability of the first blade edge and is beneficial to solving the problem of jamming; after each record of the abnormal current problem, the present application updates the remaining stirring times of the blade reverse based on the cumulative record times of the abnormal current problem, which can ensure the high-fiber taste of the finally prepared slurry and avoid the deterioration of the high-fiber taste of the slurry caused by an increase in the effective pulverization time; the present application also determines the heating parameters and reverse rotation speeds corresponding to multiple rounds of reverse rotation cycles during the pulping process through the known target slurry state to achieve a diverse taste of the high-fiber slurry.

[0023] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application.

[0024] Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] The following will clearly and completely describe the technical solutions of the present application in conjunction with the drawings.

[0026] Please refer to Figure 1 , Figure 1Schematic diagram of the structure of the food processor 1 provided in an embodiment of the present application. As Figure 1 shown, the present application provides a food processor 1, which includes a blade 2, a brushless motor 3 and a controller 4. Among them, the blade 2 is connected to the brushless motor 3, and the brushless motor 3 is electrically connected to the controller 4. The brushless motor 3 is configured to drive the blade 2 to rotate forward or backward at a specified speed based on the control instruction output by the controller 4. The blade 2 has a first edge and a second edge. When the blade 2 is driven to rotate forward by the brushless motor 3, the first edge is mainly used to substantially cut and crush food materials. When the blade 2 is driven to rotate backward by the brushless motor 3, the second edge is mainly used to stir the food materials. The second edge can also assist in crushing the food materials on the basis of stirring the food materials, but the second edge cannot efficiently crush and cut large pieces of materials. When the blade 2 of the food processor 1 encounters a large piece of material and jams, the food processor usually rotates forward to substantially cut the food materials with the first edge to make the materials smaller. Specifically, the first edge and the second edge can be the sharpened part and the unsharpened part of the blade 2, and the first edge and the second edge can also be the edge position and the back position of the blade. The thickness of the second edge is usually greater than that of the first edge. Therefore, the first edge can effectively cut and crush food materials, and the second edge mainly plays a role in stirring food materials. When the brushless motor 3 drives the blade 2 to rotate, the controller 4 monitors the operating current of the brushless motor 3 in real time, that is, the stirring current, to implement the pulp making method of high-fiber slurry in the following embodiments.

[0027] Please refer to Figure 2 , Figure 2 Schematic diagram of the process of the pulp making method of high-fiber slurry provided in an embodiment of the present application. This method is applied to a food processor, and this method includes the following steps S110 to S140.

[0028] S110: When making high-fiber slurry, control the blade to rotate backward.

[0029] High-fiber slurry refers to a slurry with a relatively large particle size and a high-fiber texture obtained by rotating the blade of a food processor and subjecting food materials to preliminary crushing and long-time stirring. When the food processor makes slurry, if the blade rotates forward for a long time, a slurry with a smaller particle size and a delicate texture will be obtained eventually. Therefore, in this step, the food processor mainly makes high-fiber slurry by driving the blade to rotate backward with the brushless motor to stir the food materials with the second edge and assist in crushing.

[0030] S120: When the blade rotates backward, if the stirring current reaches the preset current threshold, record an abnormal current problem once.

[0031] The stirring current refers to the operating current of the brushless motor detected in real time when the processor controls the brushless motor to drive the blade to rotate; the preset current threshold refers to the minimum threshold at which the controller determines that the brushless motor has an abnormal current problem when the blade is blocked by large pieces of material; the abnormal current problem refers to the situation where, due to the blade being blocked, the operating current of the brushless motor significantly increases to an abnormal range.

[0032] In this step, the controller continuously monitors the operating current (stirring current) of the brushless motor when the blade rotates in reverse to determine whether the blade is blocked. If the stirring current reaches the preset current threshold, it indicates that the blade in the processing chamber of the food processor is blocked by the material and has difficulty rotating, and the operating current of the brushless motor significantly increases to an abnormal range. There is an abnormal current problem caused by the blade being blocked in the food processor. Therefore, the controller records an abnormal current problem for this abnormal stirring current and calculates the cumulative number of recorded abnormal current problems.

[0033] S130: If the cumulative number of recorded abnormal current problems is less than the preset number threshold, the controller switches the rotation direction of the blade from reverse to forward through the brushless motor.

[0034] The preset number threshold refers to the cumulative number of occurrences of abnormal current problems caused by blockage during the process of the food processor making high-fiber slurry, which reaches the level that requires the food processor to alarm. In this step, the controller determines whether to control the food processor to alarm based on the cumulative number of recorded abnormal current problems. When the cumulative number of recorded abnormal current problems is less than the preset number threshold, the food processor does not alarm temporarily. The controller controls the brushless motor to switch the rotation direction, and the brushless motor drives the blade to switch from reverse to forward, so that the blade in the processing chamber can quickly leave the blocked area. At the same time, the first blade is used to further cut the large pieces of material to make them smaller, so as to solve the problem of the blade being blocked and eliminate the hidden danger that the blade will still be blocked by large pieces of material during subsequent reverse rotation.

[0035] S140: When the blade rotates forward, if the stirring current is always lower than the preset current threshold within the preset time period, the controller switches the rotation direction of the blade from forward to reverse through the brushless motor to continue stirring the ingredients.

[0036] The preset duration refers to the waiting duration for the controller to determine whether the jam problem has been solved by the forward rotation of the blade. When the controller drives the blade to rotate forward by the brushless motor to crush the food materials with the first blade, it continues to monitor whether the operating current of the brushless motor for driving the blade to rotate is always lower than the preset current threshold, so as to further determine whether the food processor will still have an abnormal current problem caused by jamming within the preset duration after the blade switches to forward rotation. In this step, when the blade rotates forward, if the operating current of the brushless motor for driving the blade to rotate is always lower than the preset current threshold within the preset duration, it indicates that the food processor does not encounter a jamming problem when the blade rotates forward, and after the forward rotation for the preset duration, the blade has further crushed the material that caused the jamming most recently with the first blade, that is, the jamming problem is automatically solved. Thus, when the controller does not find an abnormal current problem after the preset duration, it switches the rotation direction of the blade from forward to reverse through the brushless motor, so as to extend the total duration of the blade rotating in reverse to stir the food materials as much as possible, shorten the total duration of the blade rotating forward to finely crush the food materials as much as possible, and ensure the high-fiber texture of the high-fiber slurry finally prepared by the food processor.

[0037] Based on the above solution, the present application obtains a slurry with a larger particle size and a high-fiber texture by stirring the food materials with the second blade in reverse rotation; after detecting an abnormal current problem caused by the blade jamming, the present application does not alarm temporarily when the cumulative recording times of the abnormal current problem do not reach the preset number threshold, switches the rotation direction of the blade from reverse to forward, so that the blade quickly leaves the jamming area, and effectively crushes and cuts the food materials with the first blade, thereby making the materials smaller and effectively solving the jamming problem; after the blade rotates forward, the present application continues to monitor the stirring current within the preset duration to confirm whether the food processor substantially solves the jamming problem, and automatically resumes reverse rotation after confirming that the jamming problem is solved, and continues to make the high-fiber slurry by the way of stirring and assisting in crushing the food materials with the second blade, so as to ensure the production quality of the high-fiber slurry. Therefore, the present application has the advantages of reducing the alarm frequency, automatically solving the jamming fault and resuming the pulping work, improving the pulping efficiency, pulping quality, working intelligence and working reliability of the food processor.

[0038] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a method for preparing a high-fiber slurry provided by an embodiment of the present application. This method is applied to a food processor, and this method includes the following steps S210 to step S300.

[0039] S210: When making the high-fiber slurry, control the blade to rotate in reverse and obtain the stirring current;

[0040] High-fiber slurry refers to the slurry with larger particle size and high-fiber texture obtained by initially crushing and long-time stirring of the materials in the food processor; the stirring current refers to the operating current of the brushless motor detected in real time when the processor controls the brushless motor to drive the blade to rotate. In this step, when making high-fiber slurry, the food processor controls the blade to reverse for a long time, and the blade continuously stirs the food ingredients with the second edge and assists in crushing to obtain a slurry with larger particle size and high-fiber texture; at the same time, when the brushless motor drives the blade to rotate, the controller monitors the stirring current of the brushless motor in real time, and further judges whether the food processor has an abnormal current problem due to the blade being blocked by the food ingredients based on the magnitude of the stirring current.

[0041] S220: Whether the stirring current reaches the preset current threshold.

[0042] The preset current threshold refers to the minimum judgment threshold at which the operating current of the brushless motor will increase significantly when the blade is blocked by large pieces of materials, and the controller can determine that the brushless motor has an abnormal current problem; in this step, the controller judges whether the stirring current reaches the preset current threshold based on the stirring current detected in real time, and further judges whether the brushless motor has an abnormal current problem. If the stirring current reaches the preset current threshold, the controller executes step S230; if the stirring current does not reach the preset current threshold, the controller continues to execute step S210.

[0043] S230: If the stirring current reaches the preset current threshold, record an abnormal current problem once, and judge whether the cumulative record times of the abnormal current problem are less than the preset times threshold.

[0044] If the stirring current reaches the preset current threshold, it indicates that the food processor has an abnormal current problem caused by the blade being blocked. The controller stops the blade from rotating through the brushless motor until the duration of the blade stopping rotation reaches the stationary duration. Stopping rotation and maintaining the stationary duration is to give the brushless motor a certain buffer time after current overload to avoid excessive temperature rise of the brushless motor. In addition, when the blade stops rotating, the slurry in the processing chamber will continue to rotate due to inertia, and there is also a chance to impact the materials at the blade-blocked position to make them move. At the same time, the controller records the abnormal current problem and calculates the cumulative record times of the abnormal current problem, and then judges whether the cumulative record times are less than the preset times threshold. If the cumulative record times are less than the preset times threshold, the food processor does not alarm temporarily, and the controller executes step S240 after the blade stop duration reaches the stationary duration; if the cumulative record times reach the preset times threshold, the controller executes step S300 to control the food processor to alarm.

[0045] For the determination of the preset current threshold and the preset number threshold, it is determined before the food processor starts the pulping operation. The controller determines the preset current threshold corresponding to the current anomaly problem and / or the preset number threshold corresponding to the current anomaly alarm based on the type of ingredients corresponding to the known high-fiber slurry (usually preset by the user) and / or the blade rotation direction. For example, before controlling the food processor to start the pulping operation, the controller determines the type of ingredients of the high-fiber slurry. If the type of ingredients corresponding to the high-fiber slurry is hard beans or grains, the preset current threshold and the preset number threshold determined by the controller for hard beans or grains are larger than those for fruits and vegetables. The preset current thresholds determined by the controller for the forward and reverse rotations of the blade can be the same or different.

[0046] In one embodiment, after the controller obtains the cumulative record count of the current anomaly problem, if the cumulative record count of the current anomaly problem is less than the preset number threshold, the controller can determine the rotational speed increment value corresponding to the next rotation of the blade based on the cumulative record count, and then calculate the target rotational speed value for the next rotation of the blade. The rotational speed increment value refers to the increased rotational speed value of the target rotational speed for the next rotation of the blade compared to the current rotational speed of the blade during its most recent rotation. The rotational speed increment value can increase with the growth of the cumulative record count, can decrease with the growth of the cumulative record count, or the rotational speed increment value can also remain constant. Specifically, the value of the rotational speed increment can be 0 (constant rotational speed), a positive number (increasing rotational speed), or a negative number (decreasing rotational speed). For example, the preset number threshold is 3 times. When the cumulative record count of the current anomaly problem is 1 time, the rotational speed increment value is +1000 rpm (the rotational speed increases by 1000 rpm first), and when the cumulative record count is 2 times, the rotational speed increment value is still +1000 rpm (the rotational speed increases by 1000 rpm again); for example, the preset number threshold is 3 times. When the cumulative record count of the current anomaly problem is 1 time, the rotational speed increment value is -1000 rpm (the rotational speed decreases by 1000 rpm first), and when the cumulative record count is 2 times, the rotational speed increment value is +1000 rpm (the rotational speed increases by 1000 rpm again); for another example, the preset number threshold is 3 times. When the cumulative record count of the current anomaly problem is 1 time, the rotational speed increment value is 0 rpm (the rotational speed remains unchanged first); when the cumulative record count of the current anomaly problem is 2 times, the rotational speed increment value is +1000 rpm (the rotational speed increases by 1000 rpm again).

[0047] S240: After the stop duration reaches the stationary duration, drive the blade to rotate in the forward direction at the first target rotational speed through the brushless motor.

[0048] The first target speed refers to the target speed of the blade after the controller detects an abnormal current problem during the reverse rotation of the blade and switches the rotation direction of the blade to forward rotation through the brushless motor. In this step, after the stationary time of the blade reaches the static time, the controller controls the brushless motor to drive the blade to start rotating at the first target speed in the forward rotation direction, so that the blade leaves the material jamming position, and at the same time uses the first cutting edge to further cut the large and hard materials that cause the blade to jam, making the materials smaller and preventing the blade from being jammed again when stirring the ingredients in reverse rotation later. Optionally, the static time is 10s, and the specific value of the static time can also be set to other values according to factors such as the product parameters of the brushless motor, and is not limited here.

[0049] In an embodiment, if the cumulative record count of the abnormal current problem is less than the preset count threshold, the controller first determines the first target speed of the blade during forward rotation based on the initial speed during the reverse rotation of the blade. Specifically, the controller calculates the first target speed based on the initial speed, as well as the known ingredient information and / or the preset speed adjustment value; the first target speed is not lower than the initial speed. For example, when the initial speed during the reverse rotation of the blade is 1000 rpm and the preset speed adjustment value is 0, the controller calculates that the first target speed is still the initial speed of 1000 rpm; when the preset speed adjustment value is +1000 rpm, the controller calculates that the first target speed is 2000 rpm; when the preset speed adjustment value is -500 rpm, the controller calculates that the first target speed is 500 rpm. Or, the controller determines that the speed adjustment value is +1000 rpm based on the known ingredient information (hard ingredients such as beans and grains), and calculates the first target speed as 2000 rpm based on the initial speed of 1000 rpm during the reverse rotation of the blade; the controller determines that the speed adjustment value is -500 rpm based on the known ingredient information (fruits and vegetables), and calculates the first target speed as 500 rpm based on the initial speed of 1000 rpm during the reverse rotation of the blade.

[0050] S250: Whether the stirring current reaches the preset current threshold within the preset duration.

[0051] The preset duration refers to the waiting time for the controller to determine whether the jamming problem has been solved by the forward rotation of the blade. In this step, the controller judges whether the stirring current reaches the preset current threshold based on the real-time detected stirring current, and further judges whether there is an abnormal current problem when the brushless motor drives the blade to rotate forward. If the stirring current reaches the preset current threshold, the controller executes step S260; if the stirring current does not reach the preset current threshold, the controller continues to execute step S210, that is, still controls the brushless motor to drive the blade to rotate in reverse at the initial speed. Optionally, the preset duration corresponding to the first forward rotation is 10s, and the specific value of the preset duration can also be set to other values according to factors such as the product parameters of the brushless motor and the forward rotation sequence, and is not limited here.

[0052] S260: If the stirring current reaches the preset current threshold, record an abnormal current problem once, and determine whether the cumulative record count of the abnormal current problem is less than the preset count threshold.

[0053] This step is similar to the above step S230. For specific details, please refer to step S230 and will not be elaborated here. If so, that is, the cumulative record count is less than the preset count threshold, execute step S270; if not, that is, the cumulative record count reaches the preset count threshold, execute step S300.

[0054] S270: After the stop duration reaches the stationary duration, drive the blade to rotate in the forward direction at the second target speed by the brushless motor.

[0055] When the blade rotates forward, if the stirring current reaches the preset current threshold within the preset duration, control the blade to stop rotating and record an abnormal current problem once. If the cumulative record count of the abnormal current problem is less than the preset count threshold, when the stop duration of the blade reaches the stationary duration, control the blade to continue rotating in the forward direction at the second target speed; the second target speed can be greater than the first target speed. After the controller controls the blade to stop rotating, calculate the second target speed based on the first target speed and the preset speed increment value (speed adjustment value); or, the controller calculates the second target speed based on the initial speed when the blade rotates in reverse, the cumulative record count, and the preset speed adjustment value. For example, the initial speed of the blade when rotating in reverse is 1000 rpm; after the first occurrence of the jam problem (abnormal current problem), after the controller controls the blade to stop rotating according to the stationary duration, determine that the first target speed corresponding to the first forward rotation is 2000 rpm; when the blade encounters another jam problem (abnormal current problem) during the first forward rotation, after the controller controls the blade to stop rotating according to the stationary duration, determine that the second target speed corresponding to the second forward rotation is 3000 rpm.

[0056] S280: Whether the stirring current reaches the preset current threshold within the preset duration.

[0057] In this step, the controller determines whether the stirring current reaches the preset current threshold based on the real-time detected stirring current, and further determines whether an abnormal current problem occurs when the brushless motor drives the blade to rotate forward for the second time. If the stirring current reaches the preset current threshold, the controller records an abnormal current problem once. At this time, the cumulative record count of the abnormal current problem has reached the preset count threshold (3 times). If the speed is continuously increased for forward rotation, it may cause damage to the brushless motor. Therefore, an alarm needs to be processed, that is, the controller executes step S300; if the stirring current does not reach the preset current threshold, the controller continues to execute step S210, that is, still controls the brushless motor to drive the blade to rotate in reverse at the initial speed. Optionally, the preset duration corresponding to the second forward rotation is 5 s. The specific value of the preset duration can also be set to other values and will not be limited here.

[0058] S300: Alarm prompt.

[0059] In this step, if the cumulative record count of the abnormal current problem reaches the preset count threshold, for example, when the brushless motor drives the blade to rotate forward for the second time, an abnormal current problem still occurs, and the cumulative record count of the abnormal current problem reaches three times, the controller controls the food processor to alarm for the abnormal current. Specifically, the cumulative record count reaching the preset count threshold corresponds to multiple situations. For example, when the preset count threshold is 3 times, the controller detects an abnormal current problem each time the brushless motor drives the blade to rotate backward at the initial speed and does not detect an abnormal current problem when the blade rotates forward; or, the controller detects an abnormal current problem when the brushless motor drives the blade to rotate backward at the initial speed for the first time, detects an abnormal current problem after the brushless motor drives the blade to switch from reverse to forward for the first time, does not detect an abnormal current problem when the brushless motor drives the blade to rotate forward for the second time and the forward speed increases, and detects an abnormal current problem again when the brushless motor drives the blade to switch back to reverse; or, the controller detects an abnormal current problem when the brushless motor drives the blade to rotate backward at the initial speed for the first time and detects an abnormal current problem in the subsequent two consecutive forward rotations of the brushless motor driving the blade, etc. In the above situations, the controller detects the abnormal current problem three times. When the controller detects the abnormal current problem for the third time, it controls the food processor to issue an alarm prompt for the abnormal current. In other embodiments of the present application, the preset count threshold can also be set to other values, which will not be elaborated here.

[0060] After detecting the abnormal current problem, the controller can, after the blade stops rotating for a duration reaching the stationary duration, determine the next forward rotation speed based on the most recent rotation direction of the blade, the initial speed (the most recent rotation speed), the preset speed adjustment rule, or the speed adjustment value (the speed increment value) until the cumulative record count of the abnormal current problem reaches the preset count threshold.

[0061] In one embodiment, when the food processor makes high-fiber slurry, the brushless motor is used to control the blade to perform multiple rounds of cyclic stirring in the reverse direction. Before controlling the blade to reverse, the pulping method further includes: S200: Based on the known target slurry state, determine the target heating gear and the initial reverse rotation speed corresponding to each round of cyclic stirring.

[0062] The target slurry state refers to the specific state of the high-fiber slurry made by the food processor. For example, the food processor can make paste-like high-fiber slurry or thick-soup-like high-fiber slurry. Before the controller controls the brushless motor to drive the blade to start multiple rounds of reverse cyclic stirring, the controller, based on the known target slurry state, searches for the processing program corresponding to the target slurry state and determines the target heating gear and the initial reverse rotation speed of each process in the processing program.

[0063] For example, when the known target slurry state is high-fiber paste, the food processor needs to perform heating twice in each reverse stirring cycle process. In the first reverse stirring cycle process, perform heating at level 7 and then at level 6. After each heating, it remains stationary for a certain period of time. Subsequently, the food processor starts reverse stirring at 1000 rpm. After the reverse stirring ends, repeat the above steps until the continuous duration reaches the preset cycle duration. Then, the food processor starts the second reverse stirring cycle process, performs heating at level 5 twice. After each heating, it remains stationary for a certain period of time. Subsequently, the food processor starts reverse stirring at 1000 rpm. After the reverse stirring ends, repeat the above steps until the continuous duration reaches the preset cycle duration. Then, the food processor starts the third reverse stirring cycle process, performs heating at level 4 and then at level 3. After each heating, it remains stationary for a certain period of time. Subsequently, the food processor starts reverse stirring at 1000 rpm. After the reverse stirring ends, repeat the above steps until the continuous duration reaches the preset cycle duration. For the details of the remaining reverse stirring cycles, please refer to the above content and will not be elaborated here.

[0064] Alternatively, when the known target slurry state is high-fiber thick soup, the food processor needs to perform heating once and stirring once in each reverse stirring cycle process. In the first reverse stirring cycle process, start reverse stirring at 500 rpm. After the reverse stirring ends, perform heating at level 8. After the heating duration reaches the preset heating duration, repeat the above steps until the continuous duration reaches the preset cycle duration. In the second reverse stirring cycle process, first perform heating at level 5. After each heating, it remains stationary for a certain period of time. Subsequently, the food processor starts reverse stirring at 500 rpm. After the reverse stirring ends, repeat the above steps until the continuous duration reaches the preset cycle duration. For the details of the remaining reverse stirring cycles, please refer to the above content and will not be elaborated here. In the embodiments of the present application, the food processor can perform a forward stirring cycle process between two reverse stirring cycle processes, or can perform a forward stirring cycle process before the start or after the end of multiple reverse stirring cycle processes.

[0065] In one embodiment, after recording an abnormal current problem once, the method for making high-fiber slurry further includes: S400: Based on the cumulative recording times of the abnormal current problem, update the remaining stirring times of the blade for the reverse direction.

[0066] The remaining stirring times refer to the number of times (or the number of reverse stirring cycle rounds) that the food processor needs to continuously reverse-stir the ingredients when subsequently making high-fiber slurry. To ensure the high-fiber texture of the finally produced high-fiber slurry, the continuous duration of the blade rotating forward to crush the ingredients should not be too long. After the controller detects an abnormal current problem and triggers the food processor to increase the forward rotation speed, the controller automatically reduces the remaining stirring times of the blade or shortens the remaining stirring duration in the reverse direction according to the cumulative record times of the abnormal current problem or the continuous duration of the blade rotating forward. For example, if the cumulative record times of the abnormal current problem reach 1 or 2, the controller updates the subsequent remaining stirring times for the blade rotating in reverse, that is, the remaining stirring times are correspondingly reduced by 1 or 2 times.

[0067] In the embodiment of the present application, when the controller detects an abnormal current problem due to ingredient jamming during the reverse rotation of the blade, it can calculate the target rotation speed when the blade switches to forward rotation based on the initial rotation speed during the reverse rotation of the blade. This target rotation speed can be equal to the initial rotation speed (constant rotation speed), less than the initial rotation speed (decreased rotation speed), or greater than the initial rotation speed (increased rotation speed); when the controller detects an abnormal current problem due to ingredient jamming during the forward rotation of the blade, it can calculate the target rotation speed when the blade rotates forward again after stopping based on the initial rotation speed during the forward rotation of the blade. This target rotation speed is generally greater than or equal to the initial rotation speed to improve the cutting ability of the tool. Specifically, the rotation speed increment corresponding to the situation of increasing the forward rotation speed of the blade (when the blade encounters jamming during forward rotation and increases the forward rotation speed to solve the jamming problem) can gradually increase, gradually decrease to 0, or remain a fixed value; the rotation speed increment corresponding to the situation of blade rotation direction switching (when the blade encounters jamming during reverse rotation and switches the rotation direction to solve the jamming problem) (the change amount of the forward rotation target rotation speed relative to the reverse rotation initial rotation speed) can increase, decrease, take a value of 0, or be a fixed value.

[0068] When the present application monitors that the stirring current is too large and the motor has an abnormal current problem, it controls the blade to stop rotating and maintains it for a certain duration, which can enable the brushless motor to have a buffer interval after current overload and prevent the motor from being damaged due to excessive temperature rise; the present application increases the forward rotation speed to solve the problem that the blade is still jammed during forward rotation, which can improve the cutting ability of the first blade; after each record of the abnormal current problem, the present application updates the remaining stirring times of the blade rotating in reverse based on the cumulative record times of the abnormal current problem, which can ensure the high-fiber texture of the finally produced slurry and avoid the deterioration of the high-fiber texture of the slurry caused by an increase in the crushing duration; the present application also determines the heating parameters and the initial reverse rotation speed corresponding to multiple rounds of reverse stirring cycle processes during the pulping process through the known target slurry state, which can achieve diverse textures of the high-fiber slurry. Therefore, the present application has the advantages of improving the pulping efficiency and quality, enhancing the reliability and intelligence of the food processor for making high-fiber slurry, and improving the user experience.
