Description

Technical Field

[0001] This invention relates to the field of control technology, and more specifically, to a cooking device and its control method, apparatus, and readable storage medium. Background Technology

[0002] High-speed blenders are a common cooking appliance in households and are widely used. When using a high-speed blender, ingredients need to be manually added to the blending chamber.

[0003] In certain scenarios, the amount of food in the mixing chamber can affect the normal operation of the cooking equipment. For example, in a mixing scenario, if there is too little food in the mixing chamber, the cooking equipment may fail to mix properly. Also, during the draining stage, it is impossible to precisely control the opening and closing of the draining valve based on the amount of food in the mixing chamber. 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 art.

[0005] Therefore, a first aspect of the present invention is to provide a method for controlling a cooking device.

[0006] A second aspect of the present invention is that a control device for a cooking apparatus is provided.

[0007] A third aspect of the invention is that it provides a control device for another cooking apparatus.

[0008] A fourth aspect of the present invention is that a readable storage medium is provided.

[0009] A fifth aspect of the present invention is that a cooking apparatus is provided.

[0010] In view of this, according to a first aspect of the present invention, the present invention provides a control method for a cooking device, the cooking device including a stirring chamber, a stirring element located in the stirring chamber, a driving element, the driving element driving the stirring element to rotate, and a data acquisition device for acquiring operating parameters of the driving element, the control method including: acquiring operating parameters acquired by the data acquisition device while the stirring element is rotating; determining the working state of the driving element based on a comparison result between the operating parameters and a preset parameter threshold; determining the position of the food in the stirring chamber based on the working state of the driving element; wherein the working state of the driving element includes an unloaded state and a loaded state, and the position of the food includes a first position state and a second position state.

[0011] The technical solution of this application proposes a control method for cooking equipment. By running the above control method, the position of the ingredients in the mixing chamber can be detected, ensuring the user experience of the cooking equipment.

[0012] Specifically, when the food added to the mixing chamber is located between the cup structure and the mixing component, the mixing component cannot come into contact with the food during operation, and its operating parameters are the same as those measured when the drive component is in an unloaded state.

[0013] Based on this, the technical solution of this application compares the operating parameters with preset parameter thresholds after obtaining the operating parameters, so as to identify whether the driving component is in an unloaded state according to the comparison result, thereby realizing the identification of the position of the food.

[0014] In the above technical solution, when the driving component is detected to be in an unloaded state, the detected food position is considered to be the first position state. Similarly, when the driving component is detected to be in a loaded state, the detected food position is considered to be the second position state.

[0015] In some technical solutions, optionally, the no-load state refers to the state in which the stirring component does not come into contact with the food during the operation of the driving component, and the loaded state is the state in which the stirring component comes into contact with the food and drives the food to move during the operation of the driving component.

[0016] In some technical solutions, the aforementioned ingredients may optionally be one or more of the following: water, beans, a mixture of water and beans, fruit, a mixture of water and fruit, rice, or a mixture of rice and water.

[0017] The position of the ingredients can be understood as the height of the ingredients in the mixing chamber. Based on this, during the operation of the driving component, the first position state refers to the height of the ingredients in the mixing chamber when the mixing component is not in contact with the ingredients, and the second position state refers to the height of the ingredients in the mixing chamber when the mixing component is in contact with the ingredients.

[0018] In some technical solutions, optionally, the position of the food is zero when there is no food in the mixing chamber.

[0019] In addition, the control method for the cooking equipment proposed in this application has the following additional technical features.

[0020] In some technical solutions, the working state of the drive unit can be optionally determined based on the comparison result between the operating parameters and the preset parameter threshold, including: when the operating parameters are less than the preset parameter threshold, the working state is an unloaded state; when the operating parameters are greater than or equal to the preset parameter threshold, the working state is a loaded state.

[0021] Specifically, after the ingredients are placed into the mixing chamber, they are suspended between the cup structure and the mixing components. Although the mixing components can rotate, they cannot contact the ingredients because the ingredients are suspended, thus preventing the ingredients from being mixed.

[0022] Based on this, the technical solution of this application uses a set acquisition device to collect the operating parameters of the driving component driving the stirring component to rotate, and then determines whether there is a situation where food is put into the stirring chamber but cannot be stirred by the stirring component based on the operating parameters of the driving component.

[0023] Normally, after the mixing components have mixed the ingredients, the operating parameters will change, such as increasing the operating power of the mixing components, increasing the operating current, and decreasing the operating speed.

[0024] As the operating state of the drive component changes from an unloaded state to a loaded state, the operating parameters change synchronously from small to large. Based on this, the operating parameters during the transition from an unloaded state to a loaded state can be obtained in advance, and then preset parameter thresholds can be set according to these operating parameters.

[0025] In some technical solutions, optionally, the acquisition device includes a current sensor to acquire operating parameters collected by the acquisition device, including: recording the current value output by the current sensor when a preset voltage turn-on angle is used as input; and using the current value output by the current sensor as an operating parameter when the deviation of the current value output by the current sensor is within a first preset range within a first time period.

[0026] In some technical solutions, optionally, the acquisition device includes a speed sensor to acquire the operating parameters collected by the acquisition device, including: when the speed deviation of the stirring piece is within a second preset range during a second time period, the voltage turn-on angle corresponding to the speed sensor is used as the operating parameter.

[0027] In some technical solutions, optionally, during the mixing stage, the control method further includes: injecting liquid into the mixing chamber when the ingredient position is in a first position state until the liquid injection volume reaches the first liquid injection volume; updating the working state of the drive component to obtain the updated ingredient position; and executing the mixing program when the updated ingredient position is in a second position state.

[0028] In this technical solution, by operating the above control method, the drawback that the ingredients to be mixed are suspended between the cup structure and the mixing components after being put into the mixing chamber, thus preventing the ingredients from being mixed by the mixing components, can be overcome. This increases the probability of the ingredients being mixed, thereby increasing the probability of successful cooking.

[0029] By injecting liquid into the mixing chamber, the food ingredients inside are mixed with the injected liquid. The liquid, being fluid, can fill the space between the cup structure and the mixing components. Simultaneously, the food ingredients are immersed in the liquid environment. As the mixing components rotate, the liquid is agitated, causing the food ingredients to tumble and come into contact with the components, thus being agitated. Clearly, injecting liquid assists the mixing components in agitating the food ingredients.

[0030] By updating the working state of the driver, the updated position of the ingredients is obtained. The updated position of the ingredients is then compared with the second position state to verify whether the mixing component can mix the ingredients. If the verification is successful, that is, if the updated position of the ingredients is the second position state, the mixing program is executed.

[0031] During this process, injecting liquid into the mixing chamber can increase the chances of successfully mixing the ingredients.

[0032] In some technical solutions, optionally, during the mixing stage, the driving component drives the stirring component to operate at a first preset power. The operating parameters include a first operating parameter corresponding to the first preset power, and the preset parameter threshold includes the first preset parameter threshold. The control method further includes: when the first operating parameter is less than the first preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the first operating parameter is greater than the first preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0033] In this technical solution, by setting a first operating power, the first operating power can be bound to the mixing stage. Then, based on the comparison result of the first operating parameter and the first preset parameter threshold, the working state of the drive component in the mixing stage is determined, thereby determining the position of the ingredients.

[0034] In some technical solutions, optionally, before acquiring the operating parameters collected by the acquisition device while the agitator is rotating, the following steps are also included: acquiring the set agitation capacity; injecting liquid into the agitation chamber until the amount of liquid injected reaches the set agitation capacity.

[0035] In this technical solution, it is considered that in certain usage scenarios, such as the preparation of certain ingredients, it is necessary to inject liquid into the mixing chamber so that the liquid injection reaches the set mixing capacity set by the user.

[0036] Based on this, the first operating parameter is the operating parameter measured by the acquisition device after the liquid injection volume in the stirring chamber reaches the set stirring capacity.

[0037] In some technical solutions, the control method may optionally include: obtaining the cumulative liquid injection volume of the mixing chamber; and executing a mixing program when the cumulative liquid injection volume is greater than or equal to the second liquid injection volume and the updated food position is still in the first position state; wherein the second liquid injection volume is greater than or equal to the first liquid injection volume.

[0038] In this technical solution, the cumulative liquid injection volume is obtained and compared with the second liquid injection volume to determine whether the cumulative liquid injection volume is too large. If the cumulative liquid injection volume is too large and the updated food position is still in the first position state, the mixing program is directly executed.

[0039] During this process, the mixing process is performed to ensure that the cooking equipment can respond to the user's operation, thereby preventing the user from thinking that the cooking equipment is malfunctioning because the mixing program is not running, which would affect the user experience.

[0040] At the same time, by setting a second liquid volume, the texture of the food obtained from beating can be reduced due to excessive liquid injection.

[0041] In some technical solutions, the control method may optionally include: obtaining the capacity range corresponding to the set stirring capacity; determining the third injection volume based on the capacity range; and determining the second injection volume based on the set stirring capacity and the third injection volume.

[0042] This technical solution specifies the value of the second liquid injection volume. This second liquid injection volume is not fixed but is related to the set mixing capacity. This ensures that the amount of liquid added to the mixing chamber before the mixing process does not exceed the third liquid injection volume, thereby increasing the success rate of mixing while minimizing the impact on the texture of the resulting food.

[0043] Optionally, in some technical solutions, when the cumulative injection volume is greater than or equal to the second injection volume and the updated food position is still in the first position state, the solution also includes: outputting a reminder message.

[0044] In this technical solution, a reminder message is output to alert the user to the current stirring status, thereby addressing the above situation from the user's perspective.

[0045] In some technical solutions, the reminder information may optionally suggest that the user add ingredients again or adjust the selected cooking function, such as selecting the liquid mixing function, in order to increase the chances of successful mixing.

[0046] In some technical solutions, optionally, during the draining stage, the control method also includes: controlling the opening and closing state of the draining valve of the cooking equipment according to the position of the ingredients.

[0047] In this technical solution, the opening and closing state of the discharge valve can be determined according to the position of the food. During this process, the control accuracy of the opening and closing timing of the discharge valve can be improved during the discharge stage, avoiding situations such as the discharge valve closing before the discharge is completed or not closing for a period of time after the discharge is completed.

[0048] In some technical solutions, optionally, the opening and closing state of the drain valve of the cooking device is controlled according to the position of the ingredients, including: when the ingredients are in the first position state, controlling the timer to start timing; when the timing duration is greater than or equal to the third duration, controlling the drain valve to close; when the ingredients are in the second position state, keeping the drain valve open and resetting the timer.

[0049] In this technical solution, when the food is detected to be in the first position, the timer is controlled to delay the closing of the slurry discharge valve. During this process, the amount of slurry residue in the mixing chamber can be reduced.

[0050] Specifically, when the food is detected to be in the first position, it is assumed that the mixing component cannot reach the food after mixing. That is, the surface of the slurry after mixing is below the mixing component, and at this time, there is still slurry residue in the mixing chamber.

[0051] Based on this, a third time interval is set to allow time for the slurry at the bottom of the mixing chamber to be discharged, and after the third time interval, the slurry discharge valve is closed to achieve complete slurry discharge.

[0052] In addition, when the food ingredient is in the second position, the timer is reset to reduce the risk of the discharge valve malfunctioning due to errors in the determination of the food ingredient's position, which could affect the discharge process.

[0053] In some technical solutions, optionally, the driving component drives the stirring component to operate at a second preset power. The operating parameters include a second operating parameter corresponding to the second preset power, and the preset parameter threshold includes the second preset parameter threshold. The control method further includes: when the second operating parameter is less than the second preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the second operating parameter is greater than or equal to the second preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0054] In this technical solution, by setting a second operating power, the second operating power can be bound to the slurry discharge stage. Then, based on the comparison result between the second operating parameters and the second preset parameter threshold, the working state of the drive component in the slurry discharge stage is determined, thereby determining the position of the food.

[0055] In some technical solutions, optionally, when the discharge valve is closed, the control drive unit drives the agitator to stop operating.

[0056] In this technical solution, the stirring component is controlled to stop operating, so that the cooking equipment can automatically stop running and return to standby mode.

[0057] According to a second aspect of the present invention, the present invention provides a control device for a cooking apparatus, the cooking apparatus including a stirring chamber, a stirring element located in the stirring chamber, a driving element, the driving element driving the stirring element to rotate, and a collection device for collecting operating parameters of the driving element, the control device including: an acquisition unit for acquiring operating parameters collected by the collection device while the stirring element is rotating; a determination unit for determining the working state of the driving element based on a comparison result of the operating parameters and a preset parameter threshold; and a processing unit for determining the position of the food in the stirring chamber based on the working state of the driving element; wherein the working state of the driving element includes an unloaded state and a loaded state, and the position of the food includes a first position state and a second position state.

[0058] The technical solution of this application proposes a control device for a cooking equipment, which can detect the position of ingredients in the mixing chamber.

[0059] Specifically, when the food added to the mixing chamber is located between the cup structure and the mixing component, the mixing component cannot come into contact with the food during operation, and its operating parameters are the same as those measured when the drive component is in an unloaded state.

[0060] Based on this, the technical solution of this application compares the operating parameters with preset parameter thresholds after obtaining the operating parameters, so as to identify whether the driving component is in an unloaded state according to the comparison result, thereby realizing the identification of the position of the food.

[0061] In the above technical solution, when the driving component is detected to be in an unloaded state, the detected food position is considered to be the first position state. Similarly, when the driving component is detected to be in a loaded state, the detected food position is considered to be the second position state.

[0062] In some technical solutions, optionally, the no-load state refers to the state in which the stirring component does not come into contact with the food during the operation of the driving component, and the loaded state is the state in which the stirring component comes into contact with the food and drives the food to move during the operation of the driving component.

[0063] In some technical solutions, the aforementioned ingredients may optionally be one or more of the following: water, beans, a mixture of water and beans, fruit, a mixture of water and fruit, rice, or a mixture of rice and water.

[0064] The position of the ingredients can be understood as the height of the ingredients in the mixing chamber. Based on this, during the operation of the driving component, the first position state refers to the height of the ingredients in the mixing chamber when the mixing component is not in contact with the ingredients, and the second position state refers to the height of the ingredients in the mixing chamber when the mixing component is in contact with the ingredients.

[0065] In some technical solutions, optionally, the position of the food is zero when there is no food in the mixing chamber.

[0066] In addition, the control device of the cooking equipment proposed in this application has the following additional technical features.

[0067] In some technical solutions, the unit is optionally used to: operate in an unloaded state when the operating parameters are less than the preset parameter threshold; and operate in a loaded state when the operating parameters are greater than or equal to the preset parameter threshold.

[0068] In some technical solutions, the acquisition device may optionally include a current sensor and an acquisition unit, specifically used for: recording the current value output by the current sensor when a preset voltage turn-on angle is used as input; and using the current value output by the current sensor as an operating parameter when the deviation of the current value output by the current sensor is within a first preset range during a first time period.

[0069] In some technical solutions, the acquisition device optionally includes a speed sensor and an acquisition unit, specifically used to: when the speed deviation of the stirring piece is within a second preset range during a second time period, use the voltage turn-on angle corresponding to the speed sensor as an operating parameter.

[0070] In some technical solutions, optionally, during the mixing stage, the processing unit is also used to: inject liquid into the mixing chamber when the food ingredient is in a first position state, until the liquid injection volume reaches the first liquid injection volume; update the working state of the drive component to obtain the updated food ingredient position; and execute the mixing program when the updated food ingredient position is in a second position state.

[0071] This technical solution overcomes the drawback that when ingredients are placed in the mixing chamber and then suspended between the cup structure and the mixing components, they cannot be mixed by the mixing components. This increases the probability of the ingredients being mixed, thereby improving the success rate of cooking.

[0072] In some technical solutions, optionally, during the mixing stage, the driving component drives the stirring component to operate at a first preset power. The operating parameters include a first operating parameter corresponding to the first preset power, and the preset parameter threshold includes a first preset parameter threshold. The processing unit is further configured to: when the first operating parameter is less than the first preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the first operating parameter is greater than the first preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0073] In this technical solution, by setting a first operating power, the first operating power can be bound to the mixing stage. Then, based on the comparison result of the first operating parameter and the first preset parameter threshold, the working state of the drive component in the mixing stage is determined, thereby determining the position of the ingredients.

[0074] In some technical solutions, optionally, before acquiring the operating parameters collected by the acquisition device while the agitator is rotating, the determining unit is also used to: acquire the set agitation capacity; inject liquid into the agitation chamber until the injection volume reaches the set agitation capacity.

[0075] In this technical solution, it is considered that in certain usage scenarios, such as the preparation of certain ingredients, it is necessary to inject liquid into the mixing chamber so that the liquid injection reaches the set mixing capacity set by the user.

[0076] Based on this, the first operating parameter is the operating parameter measured by the acquisition device after the liquid injection volume in the stirring chamber reaches the set stirring capacity.

[0077] In some technical solutions, optionally, the determining unit is also used to: obtain the cumulative liquid injection volume of the stirring chamber; and execute a stirring program when the cumulative liquid injection volume is greater than or equal to the second liquid injection volume and the updated food position is still in the first position state; wherein the second liquid injection volume is greater than or equal to the first liquid injection volume.

[0114] To better 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 accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0115] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0116] In one embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a control method for a cooking device is provided. The cooking device 200 includes a stirring chamber 202, a stirring element 204 located in the stirring chamber 202, a driving element 203, the driving element 203 driving the stirring element 204 to rotate, and a data acquisition device 206 for acquiring operating parameters of the driving element 203. The control method includes:

[0117] Step 102: While the agitator is rotating, acquire the operating parameters collected by the acquisition device;

[0118] Step 104: Determine the working state of the drive unit based on the comparison results between the operating parameters and the preset parameter thresholds;

[0119] Step 106: Determine the position of the ingredients in the mixing chamber based on the working status of the drive unit.

[0120] The working states of the drive unit include an unloaded state and a loaded state, and the position of the food ingredient includes a first position state and a second position state.

[0121] The embodiments of this application propose a control method for a cooking device. By running the above control method, the position of the ingredients in the mixing chamber can be detected.

[0122] Specifically, when the food added to the mixing chamber is located between the cup structure and the mixing component, the mixing component cannot come into contact with the food during operation, and its operating parameters are the same as those measured when the drive component is in an unloaded state.

[0123] Based on this, the embodiments of this application, after obtaining the operating parameters, compare the operating parameters with preset parameter thresholds so as to identify whether the driving component is in an unloaded state according to the comparison result, thereby realizing the identification of the food position.

[0124] In the above embodiments, when the driving component is detected to be in an unloaded state, the detected food position is considered to be in the first position state. Similarly, when the driving component is detected to be in a loaded state, the detected food position is considered to be in the second position state.

[0125] In some embodiments, optionally, the no-load state refers to the state in which the stirring component does not come into contact with the food during the operation of the driving component, and correspondingly, the loaded state is the state in which the stirring component comes into contact with the food and drives the food to move during the operation of the driving component.

[0126] In some embodiments, the ingredients may optionally be one or more of water, beans, a mixture of water and beans, fruit, a mixture of water and fruit, rice, or a mixture of rice and water.

[0127] The position of the ingredients can be understood as the height of the ingredients in the mixing chamber. Based on this, during the operation of the driving component, the first position state refers to the height of the ingredients in the mixing chamber when the mixing component is not in contact with the ingredients, and the second position state refers to the height of the ingredients in the mixing chamber when the mixing component is in contact with the ingredients.

[0128] In some embodiments, the food position is optionally zero when there is no food in the mixing chamber.

[0129] In some embodiments, optionally, the working state of the drive unit is determined based on the comparison result between the operating parameters and the preset parameter threshold, including: when the operating parameters are less than the preset parameter threshold, the working state is an unloaded state; when the operating parameters are greater than or equal to the preset parameter threshold, the working state is a loaded state.

[0130] Specifically, after the ingredients are placed into the mixing chamber, they are suspended between the cup structure and the mixing components. Although the mixing components can rotate, they cannot contact the ingredients because the ingredients are suspended, thus preventing the ingredients from being mixed.

[0131] Based on this, the embodiments of this application utilize the set acquisition device to acquire the operating parameters of the driving component driving the stirring component to rotate, and then determine whether there is a situation where food is put into the stirring chamber but cannot be stirred by the stirring component based on the operating parameters of the driving component.

[0132] Normally, after the mixing components have mixed the ingredients, the operating parameters will change, such as increasing the operating power of the mixing components, increasing the operating current, and decreasing the operating speed.

[0133] As the operating state of the drive component changes from an unloaded state to a loaded state, the operating parameters change synchronously from small to large. Based on this, the operating parameters during the transition from an unloaded state to a loaded state can be obtained in advance, and then preset parameter thresholds can be set according to these operating parameters.

[0134] In some embodiments, optionally, during the mixing stage, the control method further includes: injecting liquid into the mixing chamber when the ingredient position is in a first position state until the liquid injection amount reaches a first liquid injection amount; updating the working state of the drive component to obtain the updated ingredient position; and executing the mixing program when the updated ingredient position is in a second position state.

[0135] In this embodiment, by running the above control method, the drawback that the ingredients to be mixed are suspended between the cup structure and the mixing components after being put into the mixing chamber can be overcome, thus increasing the probability of the ingredients being mixed and thereby increasing the probability of successful cooking.

[0136] By injecting liquid into the mixing chamber, the food ingredients inside are mixed with the injected liquid. The liquid, being fluid, can fill the space between the cup structure and the mixing components. Simultaneously, the food ingredients are immersed in the liquid environment. As the mixing components rotate, the liquid is agitated, causing the food ingredients to tumble and come into contact with the components, thus being agitated. Clearly, injecting liquid assists the mixing components in agitating the food ingredients.

[0137] By updating the working state of the driver, the updated position of the ingredients is obtained. The updated position of the ingredients is then compared with the second position state to verify whether the mixing component can mix the ingredients. If the verification is successful, that is, if the updated position of the ingredients is the second position state, the mixing program is executed.

[0138] During this process, injecting liquid into the mixing chamber can increase the chances of successfully mixing the ingredients.

[0139] In some embodiments, optionally, by setting a first injection volume, automatic injection is achieved, and the embodiments proposed in this application can also achieve automatic control without user intervention in injection, thereby reducing the frequency of interaction between the user and the cooking device.

[0140] In some embodiments, the first injection volume may optionally be 30 ml, 50 ml, or related to the capacity of the stirring chamber, such as the first injection volume being one-tenth or one-fifteenth of the capacity of the stirring chamber, or the capacity corresponding to the smallest scale in the stirring chamber.

[0141] In some embodiments, a water pump may be used to inject liquid into the stirring chamber, and a Hall sensor may be used to monitor the amount of liquid injected.

[0142] In some embodiments, such as Figure 2 As shown, the cooking equipment also includes a water tank 212 for storing liquid and for supplying liquid to the water pump.

[0143] In some embodiments, the cooking apparatus 200 further includes a receiving cup 210 and / or a wastewater cup 214, thereby discharging the prepared slurry into the receiving cup 210 and discharging the wastewater generated from cleaning the stirring chamber into the wastewater cup 214.

[0144] In some embodiments, optionally, during the mixing stage, the driving component drives the stirring component to operate at a first preset power. The operating parameters include a first operating parameter corresponding to the first preset power, and the preset parameter threshold includes a first preset parameter threshold. The control method further includes: when the first operating parameter is less than the first preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the first operating parameter is greater than the first preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0145] In this embodiment, by setting a first operating power, the first operating power can be bound to the mixing stage, and then the working state of the drive unit in the mixing stage can be determined based on the comparison result of the first operating parameter and the first preset parameter threshold, thereby determining the position of the ingredients.

[0146] In some embodiments, optionally, before acquiring the operating parameters collected by the acquisition device while the agitator is rotating, the method further includes: acquiring a set agitation capacity; injecting liquid into the agitation chamber until the amount of liquid injected reaches the set agitation capacity.

[0147] In this embodiment, it is considered that in some usage scenarios, such as the preparation of certain ingredients, it is necessary to inject liquid into the stirring chamber so that the liquid injection reaches the set stirring capacity set by the user.

[0148] Based on this, the first operating parameter is the operating parameter measured by the acquisition device after the liquid injection volume in the stirring chamber reaches the set stirring capacity.

[0149] In some embodiments, optionally, certain use cases may be juice preparation or the preparation of fruit and vegetable juices.

[0150] In some usage scenarios, such as when liquid injection is not required, the stirring capacity can be set to zero.

[0151] In some embodiments, the control method may optionally further include: obtaining the cumulative liquid injection volume of the stirring chamber; and executing a stirring program when the cumulative liquid injection volume is greater than or equal to the second liquid injection volume and the updated food position is still in the first position state; wherein the second liquid injection volume is greater than or equal to the first liquid injection volume.

[0152] In this embodiment, the cumulative liquid volume is obtained and compared with the second liquid volume to determine whether the cumulative liquid volume is too large. If the cumulative liquid volume is too large and the updated food position is still in the first position state, the mixing program is executed directly.

[0153] During this process, the mixing process is performed to ensure that the cooking equipment can respond to the user's operation, thereby preventing the user from thinking that the cooking equipment is malfunctioning because the mixing program is not running, which would affect the user experience.

[0154] At the same time, by setting a second liquid volume, the texture of the food obtained from beating can be reduced due to excessive liquid injection.

[0155] In addition, the second liquid volume can be the maximum permissible liquid volume of the mixing chamber. Based on this, by directly executing the mixing program without injecting liquid into the mixing chamber again, the situation where the mixture of food and liquid in the mixing chamber overflows from the mixing chamber due to mixing during the execution of the mixing program is avoided.

[0156] In some embodiments, optionally, if the updated ingredient position is still in the first position state, liquid is injected into the mixing chamber; the cumulative liquid injection volume of the mixing chamber is obtained; if the cumulative liquid injection volume is greater than or equal to the second liquid injection volume, a mixing procedure is executed; wherein the second liquid injection volume is greater than or equal to the first liquid injection volume.

[0157] In some embodiments, the control method may optionally further include: obtaining a capacity range corresponding to a set stirring capacity; determining a third injection volume based on the capacity range; and determining a second injection volume based on the set stirring capacity and the third injection volume.

[0158] In this embodiment, a specific value for the second liquid injection volume is defined. This second liquid injection volume is not fixed but is related to the set mixing capacity. This ensures that the amount of liquid added to the mixing chamber before the mixing process is executed does not exceed the third liquid injection volume, thereby increasing the success rate of mixing while minimizing the impact on the texture of the resulting food.

[0159] In some embodiments, the capacity range may optionally include a first capacity range, a second capacity range, and a third capacity range, wherein the first capacity range is [0, 300 ml), the second capacity range is [300 ml, 600 ml), and the third capacity range is [600 ml, 900 ml]. Based on this, the third injection volume corresponding to the first capacity range is 100 ml, the third injection volume corresponding to the second capacity range is 300 ml, and the third injection volume corresponding to the third capacity range is 300 ml.

[0160] In some embodiments, the second injection volume may be the sum of the set stirring capacity and the third injection volume.

[0161] In some embodiments, optionally, if the cumulative injection volume is greater than or equal to the second injection volume and the updated food position is still the first position state, the method further includes: outputting a reminder message.

[0162] In this embodiment, a reminder message is output to remind the user to pay attention to the current stirring status, thereby solving the above situation from the user's perspective.

[0163] In some embodiments, the reminder message may optionally suggest that the user add ingredients again or adjust the selected cooking function, such as selecting the liquid mixing function, to increase the chances of successful mixing.

[0164] In some embodiments, optionally, during the draining stage, the control method further includes: controlling the opening and closing state of the draining valve of the cooking device according to the position of the ingredients.

[0165] In this embodiment, the opening and closing state of the drain valve can be determined according to the position of the food ingredients. During this process, the control accuracy of the opening and closing timing of the drain valve can be improved during the draining stage, avoiding situations such as the drain valve closing before the draining is completed or not closing for a period of time after the draining is completed.

[0166] In some embodiments, optionally, controlling the opening and closing state of the drain valve of the cooking device according to the position of the ingredients includes: controlling a timer to start timing when the ingredients are in a first position state; controlling the drain valve to close when the timing duration is greater than or equal to a third duration; and keeping the drain valve open and resetting the timer when the ingredients are in a second position state.

[0167] In this embodiment, when the food ingredient is detected to be in the first position state, the timer is controlled to delay the closing of the slurry discharge valve. During this process, the amount of slurry residue in the mixing chamber can be reduced.

[0168] Specifically, when the food is detected to be in the first position, it is assumed that the mixing component cannot reach the food after mixing. That is, the surface of the slurry after mixing is below the mixing component, and at this time, there is still slurry residue in the mixing chamber.

[0169] Based on this, a third time interval is set to allow time for the slurry at the bottom of the mixing chamber to be discharged, and after the third time interval, the slurry discharge valve is closed to achieve complete slurry discharge.

[0170] In addition, when the food ingredient is in the second position, the timer is reset to reduce the risk of the discharge valve malfunctioning due to errors in the determination of the food ingredient's position, which could affect the discharge process.

[0171] In some embodiments, optionally, the driving component drives the stirring component to operate at a second preset power, the operating parameters include a second operating parameter corresponding to the second preset power, the preset parameter threshold includes a second preset parameter threshold, and the control method further includes: when the second operating parameter is less than the second preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the second operating parameter is greater than or equal to the second preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0172] In this embodiment, by setting a second operating power, the second operating power can be bound to the slurry discharge stage. Then, based on the comparison result of the second operating parameters and the second preset parameter threshold, the working state of the drive component in the slurry discharge stage is determined, thereby determining the position of the food ingredients.

[0173] In some embodiments, optionally, when the discharge valve is closed, the control drive drives the agitator to stop operating.

[0174] In this embodiment, the stirring component is controlled to stop operating, so that the cooking equipment can automatically stop running and return to standby mode.

[0175] In some embodiments, optionally, such as Figure 4 As shown, the acquisition device includes a current sensor 2062 to acquire operating parameters collected by the acquisition device, including: recording the current value output by the current sensor when a preset voltage turn-on angle is used as input; and using the current value output by the current sensor as an operating parameter when the deviation of the current value output by the current sensor is within a first preset range within a first time period.

[0176] In this embodiment, the preset voltage turn-on angle is used to control the rotation of the motor used to drive the stirring component, thereby driving the stirring component to rotate and realizing the mixing of food. The preset voltage turn-on angle can be selected according to actual usage needs.

[0177] Specifically, when using a current sensor to measure the first operating parameter, the preset voltage turn-on angle can be selected arbitrarily. However, when using a current sensor to measure the second operating parameter, the preset voltage turn-on angle can be between 5% and 50%, so that the stirring power of the agitator is lower at this time, which facilitates slurry discharge and improves the accuracy of the measured second operating parameter.

[0178] In the above embodiments, the first preset range can be ±10%, ±5%, ±15%, or ±8%, and can be selected according to actual usage needs, which will not be elaborated here.

[0179] In the above embodiments, the first duration can be 3 seconds, 5 seconds or other values, which can be selected according to actual usage needs, and will not be elaborated here.

[0180] In one embodiment, the cooking device uses a water pump to draw liquid from the water tank and a Hall sensor to monitor the liquid injection volume. The overall process flow of the cooking device then includes:

[0181] The cooking equipment starts working, the water pump draws water, the Hall effect sensor detects the water intake (i.e., the liquid injection volume in this application), and the water pump is turned off when the water intake reaches the user-set water intake volume Vset (i.e., the set stirring capacity), and then proceeds to the next step;

[0182] If the first operating parameter is measured using a current sensor, the program will use a preset voltage turn-on angle Us (range not required) to control the motor to drive the stirring blade to rotate.

[0183] The program detects the feedback from the current sensor. When the current deviation is less than ±10% for 3 consecutive seconds, it is considered stable. If the detected current value is less than or equal to the preset current value (i.e., the first preset parameter threshold), it is considered that the blade is idling and has not successfully pulverized. At this time, water volume approximately equal to 1 cm of the height of the mixing cup is pumped in. Then, the current stability value is detected again. When the stable current value is greater than the preset current value, it is considered that pulverization is successful and proceeds to the next step; or when the total water volume (i.e., the cumulative liquid volume) reaches Vt or the machine's maximum allowable water volume (i.e., the second liquid volume), and the detection is still unsuccessful, it also proceeds to the next step. Among them, under the preset voltage turn-on angle Us, the current preset value I1, the measured current value I2 of the sample machine rotating under no-load, and the current I3 of the mixing component rotating to pulverize the food are related as follows: I2 + (I3 - I2) × 0.2 ≤ I1 ≤ I2 + (I3 - I2) × 0.8.

[0184] When the cooking equipment executes the preset program to the step requiring drainage (such as draining slurry after slurry preparation, or draining wastewater after cleaning, etc.), it proceeds to the next step; the control valve performs the valve opening operation, proceeding to the next step; using a current sensor to measure the second operating parameter, the program uses a preset voltage on-off angle Us (range 5%-50%, i.e., lower output) to control the motor to drive the stirring blade to rotate, and the program detects the feedback from the current sensor to determine the state of the liquid in the cup. If the current detection value is greater than or equal to the current preset value (i.e., the second preset parameter threshold), it is considered that the liquid has not been completely drained, and drainage continues; if it is less than the preset value and maintained for a preset time (i.e., the third duration), it is considered that the liquid has been basically drained, and proceeds to the fourth step; where, under the preset voltage on-off angle Us, the current preset value I1, the measured current value I2 of the sample machine rotating under no-load, and the current I3 of the stirring blades rotating to agitate the food are related as I2+(I3-I2)×0.2≤I1≤I2+(I3-I2)×0.8.

[0185] The third duration is represented by t1, and the time t2 is the time from the bottom edge of the stirring blade to when the liquid level is almost completely drained during the actual test of the prototype. The relationship is t2×1.2≤t1≤t2×2.

[0186] In some embodiments, optionally, such as Figure 5 As shown, the acquisition device includes a speed sensor 2064 to acquire operating parameters collected by the acquisition device, including: when the speed deviation of the stirring component is within a second preset range during a second time period, using the voltage turn-on angle corresponding to the speed sensor as the operating parameter. In this embodiment, the acquisition device is limited to using a speed sensor to acquire operating parameters, which allows the embodiments proposed in this application to be applicable to more scenarios.

[0187] In the above embodiments, the second preset range can be ±10%, ±5%, ±15%, or ±8%, and can be selected according to actual usage needs, which will not be elaborated here.

[0188] In the above embodiments, the value of the second duration can be 3 seconds, 5 seconds or other values, which can be selected according to actual usage needs, and will not be elaborated here.

[0189] In one embodiment, specifically, the overall process flow of the cooking equipment includes:

[0190] The cooking equipment starts working, the water pump draws water, the Hall effect sensor detects the water intake (i.e., the liquid injection volume in this application), and the water pump is turned off when the water intake reaches the user-set water intake volume Vset (i.e., the set stirring capacity), and then proceeds to the next step;

[0191] Using a speed sensor for measurement, the program adjusts the voltage on-off angle and the detected speed to stabilize the speed in real time at a preset speed Vs (range not required). When the speed difference is less than ±10% for 3 consecutive seconds, it is considered stable. At this time, the voltage on-off angle is judged. If the voltage on-off angle is less than or equal to the preset value of the voltage on-off angle (i.e., the first preset parameter threshold), it is considered that the blade is idling and has not been successfully pulverized. At this time, water volume approximately equal to 1 cm of the height of the mixing cup is pumped in. Then, the voltage on-off angle is continuously measured when the speed is stable. If the voltage turn-on angle is greater than the preset voltage turn-on angle value, it is considered that the pulverization is successful and proceeds to the next step; or if the total water intake (i.e., the cumulative liquid injection volume) reaches Vt or the machine's maximum allowable water intake volume (i.e., the second liquid injection volume), and the detection is still unsuccessful, it also proceeds to the next step; among them, under the preset speed Vs, the preset voltage turn-on angle U1, the voltage turn-on angle U2 when the prototype is rotating without load, and the voltage turn-on angle U3 when the water is being stirred are related as follows: U2+(U3-U2)×0.2≤U1≤U2+(U3-U2)×0.8.

[0192] When the cooking equipment executes the preset program to the step requiring slurry discharge (such as slurry discharge after slurry preparation, or wastewater discharge after cleaning, etc.), it proceeds to the next step; the slurry discharge valve is opened, and the equipment proceeds to the next step; using a speed sensor, the program adjusts the voltage on-off angle and detects the speed to keep the speed stable at the preset speed Vs (range 500-5000 RPM) in real time. At this time, the voltage on-off angle is judged. If the voltage on-off angle is greater than or equal to the preset voltage on-off angle value (i.e., the second preset parameter threshold), it is considered that the liquid has not been completely discharged, and the slurry discharge continues; if it is less than the preset value and maintained for a preset time (i.e., the third duration), it is considered that the liquid has been basically discharged; where, under the preset speed Vs, the preset voltage on-off angle U1, the voltage on-off angle U2 when the prototype is rotating without load, and the voltage on-off angle U3 when the water is stirred are related as U2+(U3-U2)×0.2≤U1≤U2+(U3-U2)×0.8.

[0193] The third duration is represented by t1, and the time t2 is the time from the bottom edge of the stirring blade to when the liquid level is almost completely drained during the actual test of the prototype. The relationship is t2×1.2≤t1≤t2×2.

[0194] In one embodiment, such as Figure 6 As shown, the control process of the cooking equipment includes:

[0195] Step 602: The user sets the juice volume and starts the process.

[0196] The juice volume is also the set stirring capacity in this application.

[0197] Step 604: Fill the water to the set capacity.

[0198] The set capacity is the same as the juice capacity mentioned above.

[0199] Step 606: Stir according to the preset output and wait for the data acquisition device to stabilize the feedback value.

[0200] Step 608: If the value fed back by the acquisition device is less than the first preset parameter threshold, and the judgment result is yes, proceed to step 610; if the judgment result is no, proceed to step 614.

[0201] Step 610: Add a small amount of pre-set liquid.

[0202] The volume of a small amount of liquid is preset as the first injection volume.

[0203] Step 612: If the water inflow reaches the maximum allowable water flow, and the result is yes, proceed to step 614; if the result is no, proceed to step 606.

[0204] The maximum allowable water volume is also known as the second injection volume.

[0205] Step 614: Execute the preset juicing process.

[0206] The preset juicing process is also known as the beating process in this application.

[0207] In this embodiment, by controlling the blending of juice and monitoring the state of the juice in the cup in real time, water is added appropriately when the ingredients are suspended and the blending blade is running idle, so as to ensure the taste while successfully making the juice and improve the success rate of the user.

[0208] In one embodiment, such as Figure 7 As shown, the control process of the cooking equipment includes:

[0209] Step 702, work proceeds to the slurry discharge stage.

[0210] Step 704: Control the slurry discharge valve to open.

[0211] Step 706: Stir at a preset low speed and detect the feedback value from the data acquisition device.

[0212] Step 708: If the value fed back by the acquisition device is less than the second preset parameter threshold, and the judgment result is yes, proceed to step 710; if the judgment result is no, proceed to step 712.

[0213] Step 710: If the duration expires and the result is yes, proceed to step 714; if the result is no, proceed to step 706.

[0214] The duration of the hold time is the duration of the timer's operation.

[0215] Step 712: Reset the duration to zero.

[0216] Step 714: Turn off the motor and the discharge valve.

[0217] In this embodiment, the motor is controlled to drive the stirring component to rotate during the slurry discharge process. During this process, the liquid volume in the cup is judged by the feedback value of the sensor, so as to control the slurry discharge valve to close in time after the liquid in the cup is discharged, so that the slurry discharge time matches the actual slurry discharge situation.

[0218] In one embodiment, such as Figure 8 As shown, the present invention provides a control device 800 for a cooking device. The cooking device includes a mixing chamber, a mixing element located in the mixing chamber, a driving element, the driving element driving the mixing element to rotate, and a collection device for collecting the operating parameters of the driving element. The control device includes: an acquisition unit 802, used to acquire the operating parameters collected by the collection device when the mixing element is rotating; a determination unit 804, used to determine the working state of the driving element based on the comparison result of the operating parameters and a preset parameter threshold; and a processing unit 806, used to determine the position of the food in the mixing chamber based on the working state of the driving element. The working state of the driving element includes an unloaded state and a loaded state, and the position of the food includes a first position state and a second position state.

[0219] The embodiments of this application propose a control device 800 for a cooking apparatus that can detect the position of ingredients within the mixing chamber.

[0220] Specifically, when the food added to the mixing chamber is located between the cup structure and the mixing component, the mixing component cannot come into contact with the food during operation, and its operating parameters are the same as those measured when the drive component is in an unloaded state.

[0221] Based on this, the embodiments of this application, after obtaining the operating parameters, compare the operating parameters with preset parameter thresholds so as to identify whether the driving component is in an unloaded state according to the comparison result, thereby realizing the identification of the food position.

[0222] In the above embodiments, when the driving component is detected to be in an unloaded state, the detected food position is considered to be in the first position state. Similarly, when the driving component is detected to be in a loaded state, the detected food position is considered to be in the second position state.

[0223] In some embodiments, optionally, the no-load state refers to the state in which the stirring component does not come into contact with the food during the operation of the driving component, and correspondingly, the loaded state is the state in which the stirring component comes into contact with the food and drives the food to move during the operation of the driving component.

[0224] In some embodiments, the ingredients may optionally be one or more of water, beans, a mixture of water and beans, fruit, a mixture of water and fruit, rice, or a mixture of rice and water.

[0225] The position of the ingredients can be understood as the height of the ingredients in the mixing chamber. Based on this, during the operation of the driving component, the first position state refers to the height of the ingredients in the mixing chamber when the mixing component is not in contact with the ingredients, and the second position state refers to the height of the ingredients in the mixing chamber when the mixing component is in contact with the ingredients.

[0226] In some embodiments, the food position is optionally zero when there is no food in the mixing chamber.

[0227] In some embodiments, optionally, the determining unit 804 is specifically used to: when the operating parameters are less than a preset parameter threshold, the working state is an unloaded state; when the operating parameters are greater than or equal to the preset parameter threshold, the working state is a loaded state.

[0228] In some embodiments, optionally, during the mixing stage, the processing unit 806 is further configured to: inject liquid into the mixing chamber when the food ingredient is in a first position state, until the liquid injection amount reaches a first liquid injection amount; update the working state of the drive component to obtain the updated food ingredient position; and execute the mixing program when the updated food ingredient position is in a second position state.

[0229] In this embodiment, the drawback of food being placed in the mixing chamber and then suspended between the cup structure and the mixing components, thus preventing the food from being mixed, can be overcome. This increases the probability of the food being mixed, thereby increasing the chances of successful cooking.

[0230] The embodiments of this application are based on the following principle: Specifically, after the ingredients to be mixed are put into the mixing chamber, they are suspended between the cup structure and the mixing element. Although the mixing element can rotate, the mixing element cannot contact the ingredients because the ingredients are suspended, and therefore, the ingredients cannot be mixed.

[0231] In some embodiments, optionally, by setting a first injection volume, automatic injection is achieved, and the embodiments proposed in this application can also achieve automatic control without user intervention in injection, thereby reducing the frequency of interaction between the user and the cooking device.

[0232] In some embodiments, the first injection volume may optionally be 30 ml, 50 ml, or related to the capacity of the stirring chamber, such as the first injection volume being one-tenth or one-fifteenth of the capacity of the stirring chamber, or the capacity corresponding to the smallest scale in the stirring chamber.

[0233] In some embodiments, optionally, during the mixing stage, the driving member drives the stirring member to operate at a first preset power. The operating parameters include a first operating parameter corresponding to the first preset power, and the preset parameter threshold includes a first preset parameter threshold. The processing unit 806 is further configured to: when the first operating parameter is less than the first preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the first operating parameter is greater than the first preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0234] In this embodiment, by setting a first operating power, the first operating power can be bound to the mixing stage, and then the working state of the drive unit in the mixing stage can be determined based on the comparison result of the first operating parameter and the first preset parameter threshold, thereby determining the position of the ingredients.

[0235] In some embodiments, optionally, before acquiring the operating parameters collected by the acquisition device while the agitator is rotating, the determining unit 804 is further configured to: acquire the set agitation capacity; inject liquid into the agitation chamber until the injection volume reaches the set agitation capacity.

[0236] In this embodiment, it is considered that in some usage scenarios, such as the preparation of certain ingredients, it is necessary to inject liquid into the stirring chamber so that the liquid injection reaches the set stirring capacity set by the user.

[0237] Based on this, the first operating parameter is the operating parameter measured by the acquisition device after the liquid injection volume in the stirring chamber reaches the set stirring capacity.

[0238] In some embodiments, optionally, certain use cases may be juice preparation or the preparation of fruit and vegetable juices.

[0239] In some usage scenarios, such as when liquid injection is not required, the stirring capacity can be set to zero.

[0240] In some embodiments, optionally, the determining unit 804 is further configured to: obtain the cumulative liquid injection volume of the stirring chamber; and execute a stirring program when the cumulative liquid injection volume is greater than or equal to the second liquid injection volume and the updated food position is still in the first position state; wherein the second liquid injection volume is greater than or equal to the first liquid injection volume.

[0241] In this embodiment, the cumulative liquid volume is obtained and compared with the second liquid volume to determine whether the cumulative liquid volume is too large. If the cumulative liquid volume is too large and the updated food position is still in the first position state, the mixing program is executed directly.

[0242] During this process, the mixing process is performed to ensure that the cooking equipment can respond to the user's operation, thereby preventing the user from thinking that the cooking equipment is malfunctioning because the mixing program is not running, which would affect the user experience.

[0243] At the same time, by setting a second liquid volume, the texture of the food obtained from beating can be reduced due to excessive liquid injection.

[0244] In addition, the second liquid volume can be the maximum permissible liquid volume of the mixing chamber. Based on this, by directly executing the mixing program without injecting liquid into the mixing chamber again, the situation where the mixture of food and liquid in the mixing chamber overflows from the mixing chamber due to mixing during the execution of the mixing program is avoided.

[0245] In some embodiments, optionally, if the updated ingredient position is still in the first position state, liquid is injected into the mixing chamber; the cumulative liquid injection volume of the mixing chamber is obtained; if the cumulative liquid injection volume is greater than or equal to the second liquid injection volume, a mixing procedure is executed; wherein the second liquid injection volume is greater than or equal to the first liquid injection volume.

[0246] In some embodiments, optionally, the determining unit 804 is further configured to: obtain a capacity range corresponding to a set stirring capacity; determine a third injection volume based on the capacity range; and determine a second injection volume based on the set stirring capacity and the third injection volume.

[0247] In this embodiment, a specific value for the second liquid injection volume is defined. This second liquid injection volume is not fixed but is related to the set mixing capacity. This ensures that the amount of liquid added to the mixing chamber before the mixing process is executed does not exceed the third liquid injection volume, thereby increasing the success rate of mixing while minimizing the impact on the texture of the resulting food.

[0248] In some embodiments, the capacity range may optionally include a first capacity range, a second capacity range, and a third capacity range, wherein the first capacity range is [0, 300 ml), the second capacity range is [300 ml, 600 ml), and the third capacity range is [600 ml, 900 ml]. Based on this, the third injection volume corresponding to the first capacity range is 100 ml, the third injection volume corresponding to the second capacity range is 300 ml, and the third injection volume corresponding to the third capacity range is 300 ml.

[0249] In some embodiments, the second injection volume may be the sum of the set stirring capacity and the third injection volume.

[0250] In some embodiments, optionally, when the cumulative injection volume is greater than or equal to the second injection volume and the updated food position is still the first position state, the determining unit 804 is further configured to: output a reminder message.

[0251] In this embodiment, a reminder message is output to remind the user to pay attention to the current stirring status, thereby solving the above situation from the user's perspective.

[0252] In some embodiments, the reminder message may optionally suggest that the user add ingredients again or adjust the selected cooking function, such as selecting the liquid mixing function, to increase the chances of successful mixing.

[0253] In some embodiments, optionally, during the draining stage, the processing unit 806 is also configured to: control the opening and closing state of the draining valve 208 of the cooking device according to the position of the ingredients.

[0254] In this embodiment, the opening and closing state of the drain valve can be determined according to the position of the food ingredients. During this process, the control accuracy of the opening and closing timing of the drain valve can be improved during the draining stage, avoiding situations such as the drain valve closing before the draining is completed or not closing for a period of time after the draining is completed.

[0255] In some embodiments, optionally, the processing unit 806 is configured to: control the timer to start timing when the food ingredient is in a first position state; control the drain valve 208 to close when the timing duration is greater than or equal to a third duration; and keep the drain valve 208 open and reset the timer when the food ingredient is in a second position state.

[0256] In this embodiment, when the food ingredient is detected to be in the first position state, the timer is controlled to delay the closing of the slurry discharge valve. During this process, the amount of slurry residue in the mixing chamber can be reduced.

[0257] Specifically, when the food is detected to be in the first position, it is assumed that the mixing component cannot reach the food after mixing. That is, the surface of the slurry after mixing is below the mixing component, and at this time, there is still slurry residue in the mixing chamber.

[0258] Based on this, a third time interval is set to allow time for the slurry at the bottom of the mixing chamber to be discharged, and after the third time interval, the slurry discharge valve is closed to achieve complete slurry discharge.

[0259] In addition, when the food ingredient is in the second position, the timer is reset to reduce the risk of the discharge valve malfunctioning due to errors in the determination of the food ingredient's position, which could affect the discharge process.

[0260] In some embodiments, optionally, the driving member drives the stirring member to operate at a second preset power, the operating parameters include a second operating parameter corresponding to the second preset power, the preset parameter threshold includes a second preset parameter threshold, and the processing unit 806 is further configured to: when the second operating parameter is less than the second preset parameter threshold, the working state is an unloaded state and the food position is a first position state; when the second operating parameter is greater than or equal to the second preset parameter threshold, the working state is a loaded state and the food position is a second position state.

[0261] In this embodiment, by setting a second operating power, the second operating power can be bound to the slurry discharge stage. Then, based on the comparison result of the second operating parameters and the second preset parameter threshold, the working state of the drive component in the slurry discharge stage is determined, thereby determining the position of the food ingredients.

[0262] In some embodiments, optionally, the determining unit 804 is further configured to: control the drive to drive the agitator to stop operation when the discharge valve is closed.

[0263] In this embodiment, the stirring component is controlled to stop operating, so that the cooking equipment can automatically stop running and return to standby mode.

[0264] In some embodiments, the acquisition device may optionally include a current sensor and an acquisition unit 802, specifically configured to: record the current value output by the current sensor when a preset voltage turn-on angle is used as input; and, if the deviation of the current value output by the current sensor is within a first preset range within a first time period, use the current value output by the current sensor as an operating parameter.

[0265] In this embodiment, the preset voltage turn-on angle is used to control the rotation of the motor used to drive the stirring component, thereby driving the stirring component to rotate and realizing the mixing of food. The preset voltage turn-on angle can be selected according to actual usage needs.

[0266] Specifically, when using a current sensor to measure the first operating parameter, the preset voltage turn-on angle can be selected arbitrarily. However, when using a current sensor to measure the second operating parameter, the preset voltage turn-on angle can be between 5% and 50%, so that the stirring power of the agitator is lower at this time, which facilitates slurry discharge and improves the accuracy of the measured second operating parameter.

[0267] In the above embodiments, the first preset range can be ±10%, ±5%, ±15%, or ±8%, and can be selected according to actual usage needs, which will not be elaborated here.

[0268] In the above embodiments, the first duration can be 3 seconds, 5 seconds or other values, which can be selected according to actual usage needs, and will not be elaborated here.

[0269] In some embodiments, the acquisition device may optionally include a speed sensor and an acquisition unit 802, specifically used to: when the speed deviation of the stirring piece is within a second preset range during a second time period, use the voltage turn-on angle corresponding to the speed sensor as an operating parameter.

[0270] In this embodiment, the acquisition device is limited to using a speed sensor to acquire operating parameters. In this embodiment, the proposed embodiments of this application can be applied to more scenarios.

[0271] In the above embodiments, the second preset range can be ±10%, ±5%, ±15%, or ±8%, and can be selected according to actual usage needs, which will not be elaborated here.

[0272] In the above embodiments, the value of the second duration can be 3 seconds, 5 seconds or other values, which can be selected according to actual usage needs, and will not be elaborated here.
