Description

Technical Field

[0001] The present invention relates to the field of control technologies, and in particular, to a food processor and its control method, device, and readable storage medium. Background Art

[0002] When the existing noodle machine discharges noodles, it is prone to trigger power protection.

[0003] In the case where the noodle machine triggers power protection, the motor for driving the noodle machine to discharge noodles will reverse or stop rotating. In the case where the motor reverses or stops rotating, the noodle discharging of the noodle machine will be interrupted, affecting the noodle discharging effect. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the first aspect of the present invention is to provide a control method for a food processor.

[0006] The second aspect of the present invention is to provide a control device for a food processor.

[0007] The third aspect of the present invention is to provide a control device for a food processor.

[0008] The fourth aspect of the present invention is to provide a readable storage medium.

[0009] The fifth aspect of the present invention is to provide a food processor.

[0010] In view of this, according to the first aspect of the present invention, the present invention provides a control method for a food processor. The food processor includes a motor, an extrusion barrel, and a screw that is drivingly connected to the motor. The screw is located in the extrusion barrel. The control method includes: controlling the motor to drive the screw to operate at a first speed; and when the duration of the screw operating at the first speed is greater than or equal to a first duration, controlling the screw to operate at a second speed, where the first speed is less than the second speed.

[0011] In this technical solution, a control method for a food processor is proposed. By running this control method, the probability of triggering power protection during the operation of the food processor can be reduced. Since the probability of triggering power protection during the operation of the food processor is reduced, the probability of the food processor's discharging process being interrupted due to triggering power protection is also reduced. Therefore, the continuity of the food processor's discharging is improved, and the discharging effect is improved.

[0012] The technical solution of this application is implemented based on the following principle. Specifically, the motor is connected to the screw. During the rotation of the motor, the screw will be driven to rotate. Since the screw is located inside the extrusion barrel, during the rotation of the screw, the food ingredients will be pushed into the extrusion barrel. The food ingredients located between the screw and the extrusion barrel are pushed by other food ingredients and the screw and are extruded from the extrusion barrel.

[0013] In the initial stage of control, the screw gap may not be filled with food ingredients. If the screw is controlled to rotate at a relatively high speed at this time, the power of the motor will increase to a very high level, which is very likely to exceed the limit power of the motor, thereby triggering power protection.

[0014] To overcome the above problems, the technical solution of this application first controls the screw to rotate at the first speed, and then controls the screw to rotate at the second speed. Since the first speed is less than the second speed, therefore, the power of the motor will not be very high at the initial stage of discharging. Therefore, the probability of triggering power protection will also be reduced, reducing the impact of power protection on the continuity of discharging.

[0015] Considering that in the initial stage of control, the screw gap will not be filled with food ingredients and the rotation process of the screw is unstable, the screw is controlled to rotate at the first speed for the first duration so that the screw gap is filled with food ingredients and enters a stable state. During the above process, since the screw gap is filled with food ingredients and enters a stable state, in this case, the discharging process will be relatively continuous when rotating at the second speed.

[0016] In one of the technical solutions, the first speed and the second speed are the rotation speeds of the screw. When the motor and the screw are directly connected, the first speed and the second speed can be the rotation speeds of the motor, that is, the motor can be controlled to rotate at the first speed and the second speed to achieve the control of the first speed and the second speed of the screw.

[0017] In one possible technical solution, the first speed and the second speed are the rotation speeds of the screw. When there is a variable speed structure connection between the motor and the screw, the rotation speed of the motor is different from that of the screw, and there is a corresponding speed correspondence relationship between the two. For example, the first speed corresponds to the third rotation speed of the motor, and the second speed corresponds to the fourth rotation speed of the motor. In this case, the motor is controlled to rotate at the third speed and the fourth speed to achieve the control of the first speed and the second speed of the screw.

[0018] In addition, the control method of the food processor proposed by the technical solution of this application also has the following additional technical features.

[0019] In the above technical solution, after the step of controlling the screw to operate at the second speed, it further includes: collecting the operating power of the motor; and controlling the motor to stop operating when the operating power is less than or equal to the preset power.

[0020] In the above technical solution, during the discharging process, the ingredients in the food processor will gradually be extruded from the extrusion barrel. As the discharging ends, the operating power of the motor will gradually decrease. By obtaining the operating power of the motor, the discharging situation of the ingredients can be judged according to the power of the motor. After the discharging ends, the food processor can automatically stop the operation of the motor, reducing the occurrence of the situation where the motor still continues to rotate after the discharging ends, thereby reducing the power consumption of the food processor.

[0021] In addition, after the discharging ends, the motor stops running. Therefore, it is possible to avoid irreversible damage caused by improper operation of the user when the motor has not stopped after the discharging ends. Among them, the irreversible damage can be damage to the motor and / or the screw caused by accidentally putting other objects, and the irreversible damage can also be that the user's hand is squeezed by the screw, etc.

[0022] In one of the technical solutions, the preset power is the maximum value of the operating power during the no-load operation of food processors of the same batch.

[0023] In one of the technical solutions, the preset power is the sum value of the maximum value of the operating power during the no-load operation of food processors of the same batch and a preset value. Among them, the preset value can be the product of the maximum value of the operating power during the no-load operation of food processors of the same batch and a preset percentage, where the preset percentage is less than or equal to five percent.

[0024] In one possible technical solution, the operating power of the motor is obtained according to a preset frequency, so as to be able to check in time whether the discharging has ended and achieve precise control of the food processor.

[0025] In any of the above technical solutions, after controlling the motor to stop running, it further includes: outputting a reminder message.

[0026] In this technical solution, by outputting a reminder message, the user can know the discharging situation of the current food processor, so that after the discharging ends, the discharging result can be processed in time, or the food processor can be processed.

[0027] In the above technical solution, the form of the reminder message includes but is not limited to lights, text, voice, and can also be a reminder through a short message.

[0028] In the above technical solution, the short message can be a short message in a mobile terminal such as a mobile phone, or a short message in an application running on a mobile terminal such as a mobile phone, such as a reminder in a public account.

[0029] In the above technical solution, the form of the reminder message is limited, so that the food processor can adapt to a variety of usage scenarios to meet the usage needs of users.

[0030] In any of the above technical solutions, when the operating power is greater than the preset power, the motor is controlled to continue running until the operating power is less than or equal to the preset power.

[0031] In this technical solution, when it is detected that the operating power exceeds the preset power, it is considered that the current motor is still discharging material during the process of driving the screw to rotate, that is, the discharging has not ended. At this time, the motor is controlled to continue running at the second rotational speed so as to continuously discharge material.

[0032] In the above control process, it can be ensured that the food processor can discharge the material completely, reducing the probability of discharging interruption and ensuring the discharging effect.

[0033] In any of the above technical solutions, it further includes: obtaining the driving voltage and operating current of the motor; determining the operating power according to the driving voltage and operating current.

[0034] In this technical solution, the calculation scheme of the operating power is defined. The operating power can be directly calculated by obtaining the driving voltage and operating current of the motor. Among them, the operating power P follows the following formula:

[0035] P = UI, where P is the operating power, U is the driving voltage, and I is the operating current.

[0036] In one possible technical solution, the driving voltage is the power supply voltage of the food processor, and the operating current can be obtained through a set current detection circuit. Among them, the current detection circuit includes a detection resistor. The detection resistor is connected in series with the motor. When the resistance value of the detection resistor is known, the voltage drop across the detection resistor is obtained, and the operating current is taken as the ratio of the voltage drop to the resistance value of the detection resistor.

[0037] In any of the above technical solutions, it further includes: obtaining the screw length of the screw; determining the first duration according to the screw length and the first rotational speed.

[0038] In this technical solution, the determination scheme of the first duration is specifically defined. In this process, the value of the first duration is associated with the screw length and the first rotational speed, so as to ensure that after the screw rotates at the first rotational speed for the first duration, the screw gap is filled with ingredients and enters a stable state, reducing the occurrence of the situation where the motor triggers power protection after the screw rotates at the first rotational speed for the first duration when the first duration is a fixed value and the screw gap is not filled with ingredients and does not enter a stable state.

[0039] In any of the above technical solutions, the ratio of the screw length to the first rotational speed is positively correlated with the first duration.

[0040] During this process, the ratio of the screw length to the first rotational speed is positively correlated with the first duration. That is, when the ratio of the screw length to the first rotational speed is larger, the first duration is longer; conversely, when the ratio of the screw length to the first rotational speed is smaller, the first duration is shorter.

[0041] In any of the above technical solutions, determining the first duration according to the screw length and the first rotational speed includes: determining the product value of a preset compensation coefficient and the screw length; determining the first duration according to the ratio of the product value to the first rotational speed.

[0042] In this technical solution, the determination scheme of the first duration is specifically defined. During this process, a compensation coefficient is introduced. By setting the compensation coefficient, the first duration determined according to the screw length and the first rotational speed can better conform to the actual usage scenario, so as to meet the user's usage requirements.

[0043] In any of the above solutions, the compensation coefficient is related to the screw length. When the screw length is determined, the compensation coefficient is determined.

[0044] In any of the above technical solutions, the value of the first duration is between 20 seconds and 100 seconds.

[0045] In this technical solution, the value range of the first duration is specifically defined. By limiting that the first duration is greater than 20 seconds, it is ensured that the screw gap is filled with food materials and enters a stable state. By limiting that the first duration is less than 100 seconds, it is avoided to discharge materials at the first rotational speed.

[0046] In one possible technical solution, the specific value of the first duration is selected according to the actual usage scenario.

[0047] In any of the above technical solutions, the second rotational speed is less than the rotational speed corresponding to the maximum power of the motor.

[0048] In this technical solution, the value range of the second rotational speed is limited. By limiting that the second rotational speed is lower than the rotational speed corresponding to the maximum power of the motor, it is avoided that during the process of the screw maintaining the second rotational speed and discharging materials, the situation of triggering power protection occurs. As discussed above, through the above limitation, the probability that the material discharging process of the food processor is interrupted due to triggering power protection is also reduced. Therefore, the continuity of the material discharging of the food processor is improved, and the discharging effect is improved.

[0049] In any of the above technical solutions, it further includes: receiving the first input of the user; determining the second rotational speed according to the first input.

[0050] In this technical solution, the method for obtaining the second rotation speed is specifically defined. It can be input according to the user's first input, or determined when different modes are selected in the first input. Among them, different modes can be thickness, hardness, width, etc.

[0051] In any of the above technical solutions, the food processor further includes: a housing, a cover body, and a stirring member. A stirring cavity is enclosed between the cover body and the housing. The stirring member is located in the stirring cavity and is drivingly connected to the motor. The stirring cavity is connected to the extrusion cylinder. The motor is controlled to drive the screw to operate at the first rotation speed, and further includes: controlling the motor to drive the stirring member to rotate. Among them, when the stirring member rotates, the materials located in the stirring cavity are stirred and pushed towards the extrusion cylinder.

[0052] In this technical solution, by defining that the food processor has a stirring cavity and a stirring member, so as to use the stirring member to realize the stirring of materials. Since the stirring cavity is communicated with the extrusion cylinder, therefore, the rotation of the stirring member can be used to continuously supply materials to the extrusion cylinder, reducing the occurrence of the situation of interrupted material discharge caused by interrupted feeding.

[0053] In the above technical solution, by defining that the stirring member and the screw are both drivingly connected to the motor, so that when the motor drives the screw to rotate, the rotation of the stirring member can be driven synchronously, reducing the occurrence of the situation of materials piling up at the inlet of the extrusion cylinder.

[0054] In addition, since the stirring member and the screw are both drivingly connected to the motor, therefore, only one motor is needed to achieve the drive, and there is no need to separately set a motor for the stirring member, reducing the space occupied by the motor of the stirring member and providing a basis for the miniaturization of the food processor. In addition, it also provides a basis for reducing the cost of the food processor.

[0055] In any of the above technical solutions, the food processor includes any one of a noodle machine, a pastry robot, a wall breaker, and a juicer.

[0056] According to the second aspect of the present invention, the present invention provides a control device for a food processor. The food processor includes a motor, an extrusion cylinder, and a screw drivingly connected to the motor. The screw is located in the extrusion cylinder. The control device includes: a first control unit for controlling the motor to drive the screw to operate at the first rotation speed; a second control unit for controlling the screw to operate at the second rotation speed when the operation duration of the screw at the first rotation speed is greater than or equal to the first duration, wherein the first rotation speed is less than the second rotation speed.

[0057] In this technical solution, a control device for a food processor is proposed. A food processor with this control device can reduce the probability of triggering power protection during operation. Since the probability of triggering power protection during the operation of the food processor is reduced, the probability that the discharging process of the food processor is interrupted due to triggering power protection is also reduced. Therefore, the continuity of the discharging of the food processor is improved, and the discharging effect is enhanced.

[0058] The technical solution of this application is implemented based on the following principle. Specifically, the motor is connected to the screw. During the rotation of the motor, the screw will be driven to rotate. Since the screw is located inside the extrusion barrel, during the rotation of the screw, the food ingredients will be pushed into the extrusion barrel. The food ingredients located between the screw and the extrusion barrel are pushed by other food ingredients and the screw and are extruded from the extrusion barrel.

[0059] In the initial stage of control, the screw gap may not be filled with food ingredients. If the screw is controlled to rotate at a relatively high speed at this time, the power of the motor will increase to a very high level and easily exceed the limit power of the motor, thereby triggering power protection.

[0060] To overcome the occurrence of the above problems, the technical solution of this application first controls the screw to rotate at a first speed, and then controls the screw to rotate at a second speed. Since the first speed is less than the second speed, the power of the motor will not be very high in the initial stage of discharging. Therefore, the probability of triggering power protection is also reduced, and the influence of power protection on the discharging continuity is reduced.

[0061] Considering that in the initial stage of control, the screw gap will not be filled with food ingredients and the rotation process of the screw is unstable, the screw is controlled to rotate at the first speed for a first period of time so that the screw gap is filled with food ingredients and enters a stable state. During the above process, since the screw gap is filled with food ingredients and enters a stable state, only in this case, the discharging process at the second speed will be relatively continuous.

[0062] In one of the technical solutions, the first speed and the second speed are the rotation speeds of the screw. When the motor is directly connected to the screw, the first speed and the second speed can be the rotation speeds of the motor, that is, the motor can be controlled to rotate at the first speed and the second speed to achieve the control of the first speed and the second speed of the screw.

[0063] In one possible technical solution, the first speed and the second speed are the rotation speeds of the screw. When there is a variable speed structure connection between the motor and the screw, the rotation speed of the motor is different from that of the screw, and there is a corresponding speed correspondence relationship between the two. For example, the first speed corresponds to the third rotation speed of the motor, and the second speed corresponds to the fourth rotation speed of the motor. In this case, the motor is controlled to rotate at the third speed and the fourth speed to achieve the control of the first speed and the second speed of the screw.

[0064] In addition, the control device of the food processor proposed by the technical solution of the present application further has the following additional technical features.

[0065] In the above technical solution, after the step of controlling the screw to run at the second rotation speed, the second control unit is further configured to: collect the operating power of the motor; and control the motor to stop running when the operating power is less than or equal to the preset power.

[0066] In the above technical solution, during the process of discharging noodles, the ingredients in the food processor will gradually be extruded from the extrusion cylinder. As the discharging ends, the operating power of the motor will gradually decrease. By obtaining the operating power of the motor, it is possible to judge the discharging situation of the ingredients according to the power of the motor. After the discharging ends, the food processor can automatically end the operation of the motor, reducing the occurrence of the situation where the motor still continues to rotate after the discharging ends, thereby reducing the power consumption of the food processor.

[0067] In addition, after the discharging ends, the motor stops running. Therefore, it is possible to avoid irreversible damage caused by improper operation of the user when the motor has not stopped after the discharging ends. Among them, the irreversible damage may be damage to the motor and / or the screw caused by accidentally putting other objects, and the irreversible damage may also be that the user's hand is squeezed by the screw, etc.

[0068] In one of the technical solutions, the preset power is the maximum value of the operating power during no-load operation of food processors in the same batch.

[0069] In one of the technical solutions, the preset power is the sum value of the maximum value of the operating power during no-load operation of food processors in the same batch and a preset value. Among them, the preset value may be the product of the maximum value of the operating power during no-load operation of food processors in the same batch and a preset percentage, and the preset percentage is less than or equal to five percent.

[0070] In one possible technical solution, the operating power of the motor is obtained according to a preset frequency, so as to be able to check in time whether the discharging has ended and achieve precise control of the food processor.

[0071] In any of the above technical solutions, after controlling the motor to stop running, the second control unit is further configured to: output a reminder message.

[0072] In this technical solution, by outputting a reminder message, the user can be informed of the discharging situation of the current food processor, so that after the discharging ends, the discharging result can be processed in time, or the food processor can be processed.

[0073] In the above technical solution, the form of the reminder message includes but is not limited to lights, text, voice, and can also be a reminder through a short message.

[0074] In the above technical solution, the short message can be a short message in a mobile terminal such as a mobile phone, or a short message in an application running on a mobile terminal such as a mobile phone, such as a reminder in a public account.

[0075] In the above technical solution, the form of the reminder message is defined so that the food processor can adapt to a variety of usage scenarios to meet the usage needs of users.

[0076] In any of the above technical solutions, when the operating power is greater than the preset power, the second control unit is specifically configured to: control the motor to continue running until the operating power is less than or equal to the preset power.

[0077] In this technical solution, when it is detected that the operating power exceeds the preset power, it is considered that the current motor is still discharging during the process of driving the screw to rotate, that is, the discharging has not ended yet. At this time, the motor is controlled to continue running at the second speed so that continuous discharging can be achieved.

[0078] In the above control process, it can be ensured that the food processor can discharge completely, reducing the probability of discharging interruption and ensuring the discharging effect.

[0079] In any of the above technical solutions, the second control unit is further configured to: obtain the driving voltage and operating current of the motor; determine the operating power according to the driving voltage and operating current.

[0080] In this technical solution, the calculation scheme of the operating power is defined. The operating power can be directly calculated by obtaining the driving voltage and operating current of the motor. Among them, the operating power P follows the following formula:

Among them, the current detection circuit includes a detection resistor. The detection resistor is connected in series with the motor. When the resistance value of the detection resistor is known, the voltage drop across the detection resistor is obtained, and the ratio of the voltage drop to the resistance value of the detection resistor is used as the operating current.

[0083] In any of the above technical solutions, the first control unit is further configured to: obtain the screw length of the screw; determine the first duration according to the screw length and the first speed.

[0084] In this technical solution, the determination method of the first duration is specifically defined. In this process, the value of the first duration is associated with the screw length and the first rotation speed, so as to ensure that after the screw rotates at the first rotation speed for the first duration, the screw gap is filled with food materials and enters a stable state, reducing the occurrence of the situation where the motor triggers power protection because when the first duration is a fixed value, after the screw rotates at the first rotation speed for the first duration, the screw gap is not filled with food materials and does not enter a stable state.

[0085] In any of the above technical solutions, the ratio of the screw length to the first rotation speed is positively correlated with the first duration.

[0086] In this process, the ratio of the screw length to the first rotation speed is positively correlated with the first duration. That is, when the ratio of the screw length to the first rotation speed is larger, the first duration is longer; conversely, when the ratio of the screw length to the first rotation speed is smaller, the first duration is shorter.

[0087] In any of the above technical solutions, the first duration is determined according to the screw length and the first rotation speed. The first control unit is specifically used for: determining the product value of the preset compensation coefficient and the screw length; determining the first duration according to the ratio of the product value to the first rotation speed.

[0088] In this technical solution, the determination method of the first duration is specifically defined. In this process, a compensation coefficient is introduced. By setting the compensation coefficient, the first duration determined according to the screw length and the first rotation speed can better conform to the actual use scenario, so as to meet the user's usage requirements.

[0089] In any of the above solutions, the compensation coefficient is related to the screw length. When the screw length is determined, the compensation coefficient is determined.

[0090] In any of the above technical solutions, the value of the first duration is between 20 seconds and 100 seconds.

[0091] In this technical solution, the value range of the first duration is specifically defined. By limiting that the first duration is greater than 20 seconds, it is ensured that the screw gap is filled with food materials and enters a stable state. By limiting that the first duration is less than 100 seconds, it is avoided to discharge materials at the first rotation speed.

[0092] In one possible technical solution, the specific value of the first duration is selected according to the actual use scenario.

By defining that the second rotation speed is lower than the rotation speed corresponding to the maximum power of the motor, it is possible to avoid the situation of triggering power protection during the process of the screw maintaining the second rotation speed and discharging materials. As discussed above, through the above definition, the probability of the food processor's discharging process being interrupted due to triggering power protection is also reduced. Therefore, the continuity of the food processor's discharging is improved, and the discharging effect is enhanced.

[0095] In any of the above technical solutions, the first control unit is further configured to: receive a first input from the user; determine the second rotation speed according to the first input.

[0096] In this technical solution, the acquisition method of the second rotation speed is specifically defined. It can be input according to the first input of the user, or determined by selecting different modes in the first input. Among them, different modes can be thickness, hardness, width, etc.

[0097] In any of the above technical solutions, the food processor further includes: a housing, a cover body, and a stirring member.

[0112] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0113] In the following description, many specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0114] The following refers to Figures 1 to 5 Describe a food processor and its control method, device, and readable storage medium according to some embodiments of the present invention.

[0115] Embodiment 1

[0116] As Figure 1 shown, according to the first aspect of the present invention, the present invention provides a control method for a food processor. The food processor includes a motor, an extrusion barrel, and a screw rod drivingly connected to the motor. The screw rod is located in the extrusion barrel. The control method includes:

[0117] Step 102, controlling the motor to drive the screw rod to run at a first speed;

[0118] Step 104, when the running duration of the screw rod at the first speed is greater than or equal to a first duration, controlling the screw rod to run at a second speed.

[0119] Wherein, the first speed is less than the second speed.

[0120] In this design, a control method for a food processor is proposed. By running this control method, the probability of triggering power protection during the operation of the food processor can be reduced. Since the probability of triggering power protection during the operation of the food processor is reduced, the probability of the food outlet process of the food processor being interrupted due to triggering power protection is also reduced. Therefore, the continuity of the food outlet of the food processor is improved, and the effect of the food outlet is improved.

[0121] The design of this application is based on the following principle. Specifically, the motor is connected to the screw rod. During the rotation of the motor, the screw rod will be driven to rotate. Since the screw rod is located in the extrusion barrel, during the rotation of the screw rod, the food ingredients will be pushed into the extrusion barrel. The food ingredients located between the screw rod and the extrusion barrel are pushed by other food ingredients and the screw rod and are extruded from the extrusion barrel.

[0122] In the initial stage of control, as Figure 2 shown, the screw rod gap may not be filled with food ingredients. If the screw rod is controlled to rotate at a relatively high speed at this time, the power of the motor will rise to a very high level, easily exceeding the limit power of the motor, and then triggering power protection.

[0123] To overcome the occurrence of the above problems, as Figure 3As shown, the design of the present application first controls the screw to rotate at the first speed, and then controls the screw to rotate at the second speed. Since the first speed is less than the second speed, the power of the motor will not be very high at the initial stage of discharging. Therefore, the probability of triggering power protection will also be reduced, and the impact of power protection on the continuity of discharging is reduced.

[0124] Considering that at the initial stage of control, the screw gap will not be filled with food materials, and the rotation process of the screw is unstable. By controlling the screw to rotate at the first speed for the first duration, the screw gap can be filled with food materials and enter a stable state. In the above process, since the screw gap is filled with food materials and enters a stable state, in this case, the discharging process at the second speed will be more continuous.

[0125] In one design, the first speed and the second speed are the rotation speeds of the screw. When the motor is directly connected to the screw, the first speed and the second speed can be the rotation speeds of the motor, that is, the motor can be controlled to rotate at the first speed and the second speed to achieve the control of the first speed and the second speed of the screw.

[0126] In one possible design, the first speed and the second speed are the rotation speeds of the screw. When there is a variable speed structure connection between the motor and the screw, the rotation speed of the motor is different from that of the screw, and there is a corresponding speed correspondence relationship between the two. For example, the first speed corresponds to the third speed of the motor, and the second speed corresponds to the fourth speed of the motor. In this case, by controlling the motor to rotate at the third speed and the fourth speed, the control of the first speed and the second speed of the screw can be achieved.

[0127] In any of the above designs, the value of the first duration is between 20 seconds and 100 seconds.

[0128] In this design, the value range of the first duration is specifically limited. By limiting the first duration to be greater than 20 seconds, it is ensured that the screw gap is filled with food materials and enters a stable state. By limiting the first duration to be less than 100 seconds, discharging at the first speed is avoided.

[0129] In one possible design, the specific value of the first duration is selected according to the actual usage scenario.

[0130] In any of the above designs, the second speed is less than the rotation speed corresponding to the maximum power of the motor.

[0131] In this design, the value range of the second rotational speed is defined. By defining that the second rotational speed is lower than the rotational speed corresponding to the maximum power of the motor, it is possible to avoid the situation of triggering power protection during the process of the screw maintaining the second rotational speed and discharging materials. As discussed above, through the above definition, the probability that the discharging process of the food processor is interrupted due to triggering power protection is also reduced. Therefore, the continuity of the discharging of the food processor is improved, and the discharging effect is enhanced.

[0132] Embodiment 2

[0133] In the above design, after the step of controlling the screw to operate at the second rotational speed, it further includes: collecting the operating power of the motor; and controlling the motor to stop operating when the operating power is less than or equal to the preset power.

[0134] In the above design, during the process of discharging noodles, the ingredients in the food processor will gradually be extruded from the extrusion barrel. As the discharging ends, the operating power of the motor will gradually decrease. By obtaining the operating power of the motor, it is possible to judge the discharging situation of the ingredients based on the power of the motor. After the discharging ends, the food processor can automatically end the operation of the motor, reducing the occurrence of the situation where the motor still continues to rotate after the discharging ends, thereby reducing the power consumption of the food processor.

[0135] In addition, after the discharging ends, the motor stops operating. Therefore, it is possible to avoid irreversible damage caused by improper operation of the user when the motor has not stopped after the discharging ends. Among them, the irreversible damage can be the damage of the motor and / or the screw caused by accidentally putting other objects, and the irreversible damage can also be that the user's hand is squeezed by the screw, etc.

[0136] In one of the designs, the preset power is the maximum value of the operating power during the no-load operation of food processors in the same batch.

[0137] In one of the designs, the preset power is the sum value of the maximum value of the operating power during the no-load operation of food processors in the same batch and a preset value. Among them, the preset value can be the product of the maximum value of the operating power during the no-load operation of food processors in the same batch and a preset percentage, and the preset percentage is less than or equal to 5%.

[0138] In one possible design, the operating power of the motor is obtained according to a preset frequency, so as to be able to check in time whether the discharging has ended and achieve precise control of the food processor.

[0139] In any of the above designs, when the operating power is greater than the preset power, control the motor to continue operating until the operating power is less than or equal to the preset power.

[0140] In this design, when it is detected that the operating power exceeds the preset power, it is considered that the current motor is still discharging while driving the screw to rotate, that is, the discharging has not ended yet. At this time, the motor is controlled to continue running at the second speed so that continuous discharging can be achieved.

[0141] In the above control process, it can be ensured that the food processor can discharge completely, reducing the probability of discharging interruption and ensuring the discharging effect.

[0142] In any of the above designs, it further includes: obtaining the driving voltage and operating current of the motor; determining the operating power according to the driving voltage and operating current.

[0143] In this design, the calculation scheme of the operating power is defined. The operating power can be directly calculated by obtaining the driving voltage and operating current of the motor. Among them, the operating power P follows the following formula:

[0144] P = UI, where P is the operating power, U is the driving voltage, and I is the operating current.

[0145] In one possible design, the driving voltage is the power supply voltage of the food processor, and the operating current can be obtained through a set current detection circuit. Among them, the current detection circuit includes a detection resistor, and the detection resistor is connected in series with the motor. Given the resistance value of the detection resistor, by obtaining the voltage drop across the detection resistor and using the ratio of the voltage drop to the resistance value of the detection resistor as the operating current.

[0146] As Figure 4 shown, the control method of the food processor includes:

[0147] Step 402, determine the first duration;

[0148] Step 404, control the motor to drive the screw to run at the first speed;

[0149] Step 406, determine whether the continuous duration of running at the first speed is greater than the first duration. If the result is yes, execute step 408; if the result is no, execute step 404;

[0150] Step 408, control the motor to drive the screw to run at the second speed;

[0151] Step 410, collect the operating power of the motor;

[0152] Step 412, determine whether the operating power is less than or equal to the preset power. If the judgment result is yes, execute step 414; if the judgment result is no, execute step 410;

[0153] Step 414, control the motor to stop running.

[0154] In this design, by running this control method, the probability of the food processor triggering power protection during operation can be reduced. Since the probability of the food processor triggering power protection during operation is reduced, the probability of the food processor's discharging process being interrupted due to triggering power protection is also reduced. Therefore, the continuity of the food processor's discharging is improved, and the discharging effect is enhanced.

[0155] Embodiment III

[0156] In any of the above designs, after controlling the motor to stop running, it further includes: outputting a reminder message.

[0157] In this design, by outputting a reminder message, the user can be informed of the current discharging situation of the food processor, so that after the discharging is completed, the discharging result can be processed in a timely manner, or the food processor can be processed.

[0158] In the above design, the form of the reminder message includes but is not limited to lights, text, voice, and can also be a reminder via a short message.

[0159] In the above design, the short message can be a short message in a mobile terminal such as a mobile phone, or a short message in an application running on a mobile terminal such as a reminder in a public account.

[0160] In the above design, the form of the reminder message is defined so that the food processor can adapt to various usage scenarios to meet the user's usage requirements.

[0161] Embodiment IV

[0162] In any of the above designs, it further includes: obtaining the screw length of the screw; determining a first duration according to the screw length and the first rotation speed.

[0163] In this design, the determination scheme of the first duration is specifically defined. In this process, the value of the first duration is associated with the screw length and the first rotation speed, so as to ensure that after the screw rotates at the first rotation speed for the first duration, the screw gap is filled with ingredients and enters a stable state, reducing the occurrence of the situation where the motor triggers power protection because when the first duration is a fixed value, after the screw rotates at the first rotation speed for the first duration, the screw gap is not filled with ingredients and does not enter a stable state.

[0164] In any of the above designs, the ratio of the screw length to the first rotation speed is positively correlated with the first duration.

[0165] In this process, the ratio of the screw length to the first rotation speed is positively correlated with the first duration. That is, when the ratio of the screw length to the first rotation speed is larger, the first duration is longer; conversely, when the ratio of the screw length to the first rotation speed is smaller, the first duration is shorter.

[0166] In any of the above designs, determining the first duration according to the screw length and the first rotational speed includes: determining the product value of a preset compensation coefficient and the screw length; determining the first duration according to the ratio of the product value to the first rotational speed.

[0167] In this design, a specific scheme for determining the first duration is defined. In this process, a compensation coefficient is introduced. By setting the compensation coefficient, the first duration determined according to the screw length and the first rotational speed can better conform to the actual usage scenario, so as to meet the user's usage requirements.

[0168] In any of the above solutions, the compensation coefficient is related to the screw length. When the screw length is determined, the compensation coefficient is determined.

[0169] In any of the above designs, it further includes: receiving the first input of the user; determining the second rotational speed according to the first input.

[0170] In this design, a specific method for obtaining the second rotational speed is defined. It can be input according to the first input of the user, or determined when different modes are selected in the first input. Among them, different modes can be thickness, hardness, width, etc.

[0171] In any of the above designs, the food processor further includes: a housing, a lid, and a stirring member. A stirring cavity is enclosed between the lid and the housing. The stirring member is located in the stirring cavity and is drivingly connected to the motor. The stirring cavity is connected to the extrusion barrel. Control the motor to drive the screw to run at the first rotational speed, and it further includes: controlling the motor to drive the stirring member to rotate. Among them, when the stirring member rotates, the materials located in the stirring cavity are stirred and pushed towards the extrusion barrel.

[0172] In this design, by defining that the food processor has a stirring cavity and a stirring member, the stirring of the materials can be realized by using the stirring member. Since the stirring cavity is communicated with the extrusion barrel, the rotation of the stirring member can be used to continuously supply materials to the extrusion barrel, reducing the occurrence of the situation of interrupted material discharge caused by interrupted feeding.

[0173] In the above design, by defining that the stirring member and the screw are both drivingly connected to the motor, when the motor drives the screw to rotate, the rotation of the stirring member can be driven synchronously, reducing the occurrence of the situation of materials piling up at the inlet of the extrusion barrel.

[0174] In addition, since the stirring member and the screw are both drivingly connected to the motor, only one motor is required to achieve driving, and there is no need to separately set a motor for the stirring member, reducing the space occupied by the motor of the stirring member, providing a basis for the miniaturization of the food processor. In addition, it also provides a basis for reducing the cost of the food processor.

[0175] In any of the above designs, the food processor includes any one of a noodle machine, a pastry robot, a wall breaker, and a juicer.

[0176] Embodiment 5

[0177] As Figure 5 shown, the present invention provides a control device 500 for a food processor. The food processor includes a motor, an extrusion barrel, and a screw rod drivingly connected to the motor. The screw rod is located inside the extrusion barrel. The control device includes: a first control unit 502 for controlling the motor to drive the screw rod to operate at a first speed; a second control unit 504 for controlling the screw rod to operate at a second speed when the duration of the screw rod operating at the first speed is greater than or equal to a first duration, wherein the first speed is less than the second speed.

[0178] In this design, a control device 500 for a food processor is proposed. For a food processor having this control device, the probability of triggering power protection during the operation of the food processor can be reduced. Since the probability of triggering power protection during the operation of the food processor is reduced, the probability of the food processor's discharging process being interrupted due to triggering power protection is also reduced. Therefore, the continuity of the food processor's discharging is improved, and the discharging effect is improved.

[0179] The design of this application is implemented based on the following principle. Specifically, the motor is connected to the screw rod. During the rotation of the motor, the screw rod will be driven to rotate. Since the screw rod is located inside the extrusion barrel, during the rotation of the screw rod, the food ingredients will be pushed into the extrusion barrel. The food ingredients located between the screw rod and the extrusion barrel are pushed by other food ingredients and the screw rod and are extruded from the extrusion barrel.

[0180] In the initial stage of control, the screw rod gap may not be filled with food ingredients. If the screw rod is controlled to rotate at a relatively high speed at this time, the power of the motor will increase to a very high level and it is very easy to exceed the limit power of the motor, thereby triggering power protection.

[0181] To overcome the occurrence of the above problems, the design of this application first controls the screw rod to rotate at a first speed, and then controls the screw rod to rotate at a second speed. Since the first speed is less than the second speed, the power of the motor will not be very high in the initial stage of discharging. Therefore, the probability of its triggering power protection will also be reduced, reducing the impact of power protection on the continuity of discharging.

[0182] Considering that in the initial stage of control, the screw rod gap will not be filled with food ingredients and the rotation process of the screw rod is unstable, the screw rod is controlled to rotate at the first speed for a first duration so that the screw rod gap is filled with food ingredients and enters a stable state. In the above process, since the screw rod gap is filled with food ingredients and enters a stable state, only in this case, the discharging process when rotating at the second speed will be relatively continuous.

[0183] In one of the designs, the first rotational speed and the second rotational speed are the rotational speeds of the screw. When the motor is directly connected to the screw, the first rotational speed and the second rotational speed can be the rotational speeds of the motor. That is, the motor can be controlled to rotate at the first rotational speed and the second rotational speed to control the first rotational speed and the second rotational speed of the screw.

[0184] In one possible design, the first rotational speed and the second rotational speed are the rotational speeds of the screw. When there is a variable speed structure connection between the motor and the screw, the rotational speed of the motor is different from that of the screw, and there is a corresponding speed correspondence relationship between the two. For example, the first rotational speed corresponds to the third rotational speed of the motor, and the second rotational speed corresponds to the fourth rotational speed of the motor. In this case, the motor is controlled to rotate at the third rotational speed and the fourth rotational speed to control the first rotational speed and the second rotational speed of the screw.

[0185] In the above design, after the step of controlling the screw to operate at the second rotational speed, the second control unit 504 is further configured to: collect the operating power of the motor; and control the motor to stop operating when the operating power is less than or equal to the preset power.

[0186] In the above design, during the process of discharging, the ingredients in the food processor will gradually be extruded from the extrusion barrel. As the discharging ends, the operating power of the motor will gradually decrease. By obtaining the operating power of the motor, the discharging situation of the ingredients can be judged according to the power of the motor. After the discharging ends, the food processor can automatically end the operation of the motor, reducing the occurrence of the situation that the motor still continues to rotate after the discharging ends, thereby reducing the power consumption of the food processor.

[0187] In addition, after the discharging ends, the motor stops operating. Therefore, it is possible to avoid irreversible damage caused by improper operation of the user when the motor has not stopped after the discharging ends. The irreversible damage can be damage to the motor and / or the screw caused by accidentally putting other objects, and the irreversible damage can also be that the user's hand is squeezed by the screw, etc.

[0188] In one of the designs, the preset power is the maximum value of the operating power during the no-load operation of food processors in the same batch.

[0189] In one of the designs, the preset power is the sum value of the maximum value of the operating power during the no-load operation of food processors in the same batch and a preset value. The preset value can be the product of the maximum value of the operating power during the no-load operation of food processors in the same batch and a preset percentage, where the preset percentage is less than or equal to five percent.

[0190] In one possible design, the operating power of the motor is obtained at a preset frequency so as to be able to check in time whether the discharging has ended and achieve precise control of the food processor.

[0191] In any of the above designs, after the control motor stops running, the second control unit 504 is further configured to: output a reminder message.

[0192] In this design, by outputting a reminder message, the user can be informed of the discharging situation of the current food processor, so that after the discharging is completed, the discharging result can be processed in a timely manner, or the food processor can be processed.

[0193] In the above design, the form of the reminder message includes but is not limited to lights, text, voice, and can also be a reminder via a short message.

[0194] In the above design, the short message can be a short message in a mobile terminal such as a mobile phone, or a short message in an application running on a mobile terminal such as a mobile phone, such as a reminder in a public account.

[0195] In the above design, the form of the reminder message is defined so that the food processor can adapt to a variety of usage scenarios to meet the user's usage requirements.

[0196] In any of the above designs, when the operating power is greater than the preset power, the second control unit 504 is specifically configured to: control the motor to continue running until the operating power is less than or equal to the preset power.

[0197] In this design, when it is detected that the operating power exceeds the preset power, it is considered that the current motor is still discharging during the process of driving the screw to rotate, that is, the discharging has not ended. At this time, the motor is controlled to continue running at the second speed so that continuous discharging can be achieved.

[0198] In the above control process, it can be ensured that the food processor can discharge completely, reducing the probability of discharging interruption and ensuring the discharging effect.

[0199] In any of the above designs, the second control unit 504 is further configured to: obtain the driving voltage and operating current of the motor; determine the operating power according to the driving voltage and operating current.

[0200] In this design, the calculation scheme of the operating power is defined. The operating power can be directly calculated by obtaining the driving voltage and operating current of the motor. Among them, the operating power P follows the following formula:

[0201] P = UI, where P is the operating power, U is the driving voltage, and I is the operating current.

[0202] In one possible design, the driving voltage is the power supply voltage of the food processor, and the operating current can be obtained through a set current detection circuit. The current detection circuit includes a detection resistor, where the detection resistor is connected in series with the motor. Given the resistance value of the detection resistor, by obtaining the voltage drop across the detection resistor and using the ratio of the voltage drop to the resistance value of the detection resistor as the operating current.

[0203] In any of the above designs, the first control unit 502 is further configured to: obtain the screw length of the screw; determine the first duration according to the screw length and the first rotation speed.

[0204] In this design, the determination scheme of the first duration is specifically defined. During this process, the value of the first duration is associated with the screw length and the first rotation speed, so as to ensure that after the screw rotates at the first rotation speed for the first duration, the screw gap is filled with ingredients and enters a stable state, reducing the occurrence of the situation where when the first duration is a fixed value, after the screw rotates at the first rotation speed for the first duration, the screw gap is not filled with ingredients and enters a stable state, resulting in the motor triggering power protection.

[0205] In any of the above designs, the ratio of the screw length to the first rotation speed is positively correlated with the first duration.

[0206] During this process, the ratio of the screw length to the first rotation speed is positively correlated with the first duration. That is, when the ratio of the screw length to the first rotation speed is larger, the first duration is longer; conversely, when the ratio of the screw length to the first rotation speed is smaller, the first duration is shorter.

[0207] In any of the above designs, to determine the first duration according to the screw length and the first rotation speed, the first control unit is specifically configured to: determine the product value of a preset compensation coefficient and the screw length; determine the first duration according to the ratio of the product value to the first rotation speed.

[0208] In this design, the determination scheme of the first duration is specifically defined. During this process, a compensation coefficient is introduced. By setting the compensation coefficient, the first duration determined according to the screw length and the first rotation speed can better conform to the actual usage scenario to meet the user's usage requirements.

[0209] In any of the above solutions, the compensation coefficient is related to the screw length. When the screw length is determined, the compensation coefficient is determined.

[0210] In any of the above designs, the value of the first duration is between 20 seconds and 100 seconds.

[0211] In this design, the value range of the first duration is specifically limited. By limiting the first duration to be greater than 20 seconds, it is ensured that the screw gap is filled with ingredients and enters a stable state. By limiting the first duration to be less than 100 seconds, it is avoided to discharge materials at the first rotation speed.

[0212] In one possible design, the specific value of the first duration is selected according to the actual usage scenario.

[0213] In any of the above designs, the second rotation speed is less than the rotation speed corresponding to the maximum power of the motor.

[0214] In this design, the value range of the second rotation speed is limited. By limiting the second rotation speed to be lower than the rotation speed corresponding to the maximum power of the motor, it is avoided that during the process of the screw maintaining the second rotation speed and discharging materials, the situation of triggering power protection occurs. As discussed above, through the above limitation, the probability that the discharging process of the food processor is interrupted due to triggering power protection is also reduced. Therefore, the continuity of the discharging of the food processor is improved, and the discharging effect is improved.

[0215] In any of the above designs, the first control unit 502 is further configured to: receive the first input of the user; determine the second rotation speed according to the first input.

[0216] In this design, the acquisition method of the second rotation speed is specifically limited. It can be input according to the first input of the user, or determined when different modes are selected in the first input. Among them, different modes can be thickness, hardness, width, etc.

[0217] In any of the above designs, the food processor further includes: a housing, a cover, and a stirring member. A stirring cavity is enclosed between the cover and the housing. The stirring member is located in the stirring cavity and is drivingly connected to the motor. The stirring cavity is connected to the extrusion cylinder. The motor is controlled to drive the screw to operate at the first rotation speed, and further includes: controlling the motor to drive the stirring member to rotate. Among them, under the rotation of the stirring member, the materials located in the stirring cavity are stirred and pushed towards the extrusion cylinder.
