A fourth aspect of the present invention provides a cooking appliance.

A fifth aspect of the present invention proposes a cooking appliance.

In view of the above, the first aspect of the present invention provides a method for controlling a cooking appliance, wherein the cooking appliance includes a motor and a stirrer, and an output end of the motor is connected to the stirrer; the control method comprises the following steps: acquiring the weight of food materials in the cooking appliance; and controlling the motor to work according to the operation parameters corresponding to the weight according to the weight of the food material so as to drive the stirrer to stir.

According to the control method of the cooking appliance, firstly, when the food materials are thrown into the cooking appliance, the weight of the food materials in the cooking appliance is obtained and recorded as the initial weight of the food materials, and after the cooking appliance starts to operate, the weight of the food materials in the cooking process is obtained in real time, so that the operation of a motor of the cooking appliance is controlled according to the weight of the food materials in the cooking appliance.

Specifically, in the process of cooking the food material by the cooking appliance, the food material generally needs to be heated, and in the heating process, the moisture of the food material gradually evaporates, so that the weight of the food material is continuously reduced. With the gradual reduction of moisture in the food material, the whole food material can become more viscous, and therefore, when the food material is stirred by the stirrer, the resistance of the food material to the stirrer can be gradually increased, and therefore, under the condition that the operation parameters of the motor are not changed, the rotating speed of the stirrer can be slowed down, so that the stirring effect of the stirrer is reduced, and further the cooking effect of the food material is reduced.

Further, in the cooking process, when the weight of the food materials in the cooking appliance changes, the motor is controlled to operate according to the operation parameters corresponding to the current weight of the food materials, so that the stirring process of the stirrer is not affected by the change of the weight of the food materials, the stirrer can be stirred according to the requirement of the food materials in the whole cooking process, and the cooking effect of the cooking appliance is guaranteed.

Specifically, cooking utensil can be provided with weighing transducer, and weighing transducer can set up in cooking utensil's the bottom in the culinary art chamber, and the culinary art chamber is used for holding edible material to can guarantee to cook the accuracy of the edible material weight measurement of intracavity.

Specifically, the food in the cooking appliance can be a sauce product or a drinking product, and the like, and the food needs to be continuously stirred in the cooking process to ensure the uniformity of various raw materials in the food, so that the cooked food can meet the requirements of users.

According to the control method of the cooking appliance, in the operation process of the cooking appliance, the weight of the food material in the cooking cavity of the cooking appliance is measured, and the operation parameters of the motor of the cooking appliance are controlled according to the weight of the food material, so that the stirring process of the stirrer connected with the output end of the motor is not influenced by the weight change of the food material, the stirrer is enabled to stir the food material at the optimal rotating speed, and the cooking effect of the cooking appliance on the food material is further ensured.

In addition, according to the control method of the cooking appliance in the above technical solution provided by the present invention, the following additional technical features may be further provided:

in the above technical solution, further, the step of controlling the operation parameters of the motor according to the weight of the food material includes: and controlling the motor to operate at a first operation parameter based on the fact that the ratio of the current weight of the food material to the initial weight of the food material is greater than a first preset value.

In the technical scheme, the food material weight and the food material initial weight are obtained in real time through a weight sensor at the bottom of a cooking cavity of the cooking appliance in the operation process of the cooking appliance, the ratio between the current food material weight and the initial weight of the food material is determined, whether the ratio is larger than a first preset value or not is further judged, and if the ratio is larger than the first preset value, the motor is controlled to operate according to a first operation parameter.

Specifically, the cooking utensil begins to operate, when eating the material initial input culinary art chamber, the weight sensor that sets up in the cooking utensil bottom measures the edible material of culinary art intracavity, the edible material weight record that measures this moment is the initial weight of eating the material, cooking utensil passes through heating device and begins to cook the chamber heating, motor start simultaneously, the motor moves and drives with first operating parameter and connects the agitator rotation, in order to realize that the agitator stirs the edible material of culinary art intracavity, when heating the stirring, the weight sensor that is located the cooking utensil bottom measures the edible material weight of culinary art intracavity in real time, until the ratio between the current weight of edible material and the initial weight of edible material reaches first default, it is great to show that the water content of current edible material differs with initial water content, first operating parameter has been unable to satisfy the stirring requirement of edible material.

In any of the above technical solutions, further, the step of controlling the operation parameters of the motor according to the weight of the food material further includes: and controlling the motor to operate at a second operation parameter based on that the ratio of the current weight of the food material to the initial weight of the food material is less than or equal to a first preset value and greater than a second preset value.

In the technical scheme, when the weight of the food material in the cooking appliance is gradually reduced to the first preset value, the motor of the cooking appliance is controlled to work according to the running parameters corresponding to the current weight, namely, when the ratio of the current weight of the food material in the cooking appliance to the initial weight of the food material is between the first preset value and the second preset value, the motor of the cooking appliance is controlled to run with the second running parameters, so that the stirring requirement for the water content of the current food material is met, and the stirring effect of the food material is ensured.

Specifically, when the ratio of the current weight of the food material to the initial weight of the food material in the cooking appliance is greater than a first preset value, the motor drives the stirrer to continuously stir the food material by using a first operation parameter, meanwhile, the heating device also continuously heats the food material in the cooking cavity, moisture in the food material is continuously evaporated, so that the weight of the food material is gradually reduced, and when the ratio of the current weight of the food material to the initial weight of the food material is reduced to be less than or equal to the first preset value, the motor operates by using a second operation parameter until the ratio of the weight reaches a second preset value.

It can be understood that, along with cooking utensil is to the continuous heating of eating the material, the moisture of eating the material constantly evaporates, lead to eating the material water content and reduce, and then the viscosity that leads to eating the material increases, at this moment, the first operating parameter of motor can't drive the agitator and carry out abundant stirring to eating the material, consequently, when the current weight of eating the material and the ratio of initial weight drop to first default, the control motor moves with the second parameter, also carries out corresponding adjustment according to the viscosity of eating the material to the rotation of agitator, in order to guarantee the stirring effect.

In any of the above technical solutions, further, the first operation parameter includes a first rotation speed and a first torque of the electric machine; the second operating parameter comprises a second rotational speed and a second torque of the electric machine; the first rotational speed is greater than the second rotational speed, and the first torque is less than the second torque.

In this technical scheme, the operating parameter of motor includes rotational speed and torque, it is corresponding, when obtaining that the edible material and the initial edible material proportion in the cooking utensil are greater than the first default of motor, the motor is with the operation of first operating parameter this moment, also control the motor and rotate with first rotational speed and first torque, because the culinary art just begins to go on, the evaporation of moisture in the edible material is less, the viscosity of edible material also is the minimum this moment, so the motor is lower to the requirement of torque, through quick rotation, can guarantee the stirring effect of edible material, it is even to guarantee to stir various materials in the edible material.

Further, when the ratio of the current weight of the food material in the cooking appliance to the weight of the initial food material is obtained, and the ratio is smaller than or equal to the first preset value and larger than the second preset value, it is indicated that moisture in the food material continues to evaporate, the viscosity increases, and at the moment, the resistance of the food material to the stirrer increases, so that in order to ensure that various materials in the food material can be uniformly stirred, the control can be performed by increasing the torque through a motor, namely, the operation is performed with a second torque larger than the first torque. Furthermore, due to the fact that the viscosity of the food materials is increased, in order to avoid the local clustering phenomenon of the food materials, the rotating speed of the motor is controlled to be reduced, and therefore the clustering phenomenon caused by the fact that the local motion of the food materials is too fast is avoided. That is, when the ratio of the current weight of the food material to the initial weight of the food material is less than or equal to the first preset value and greater than the second preset value, the motor is controlled to operate according to the second operation parameter, and the stirring effect of the food material is ensured.

In any of the above technical solutions, further, a value range of the first preset value is 0.93 to 0.87; the second preset value ranges from 0.83 to 0.77.

In the technical scheme, the value ranges of the first preset value and the second preset value can be limited according to different properties of food materials cooked by the cooking appliance and different requirements of a user on cooking effects, specifically, the value range of the first preset value is 0.93-0.87, the value range of the second preset value is 0.83-0.77, and the user can set specific values of the first preset value and the second preset value according to specific requirements of cooking so as to meet the requirements of the user.

Specifically, when making the sauce food, the first preset value may be set to 0.9, and the second preset value may be set to 0.8, that is, when the ratio of the current weight to the initial weight of the sauce food in the cooking appliance decreases to 0.9 and does not decrease to 0.8, the cooking appliance controls the motor to increase the torque and decrease the rotation speed, so as to avoid the lumping while ensuring that the amounts of the various food are uniformly stirred.

In any of the above technical solutions, further, the step of controlling the operation parameters of the motor according to the weight of the food material further includes: and controlling the motor to operate at a third operation parameter based on the ratio of the current weight of the food material to the initial weight of the food material being less than or equal to a second preset value and greater than a third preset value.

In this technical scheme, when the weight of the food material in the cooking utensil reduces to the second preset value gradually, then the motor of control cooking utensil works according to the operating parameter corresponding with current weight, promptly, when the ratio of the current weight of the food material in the cooking utensil and the initial weight of food material is between second preset value and third preset value, then the motor of control cooking utensil moves with third operating parameter to satisfy the required stirring requirement of current food material water content, guarantee the stirring effect of food material.

Specifically, when the ratio of the current weight of the food material to the initial weight of the food material in the cooking appliance is greater than a first preset value, the motor drives the stirrer to continuously stir the food material by using a first operation parameter, and meanwhile, the heating device also continuously heats the food material in the cooking cavity, moisture in the food material is continuously evaporated, so that the weight of the food material is gradually reduced.

It can be understood that, along with cooking utensil is to the continuous heating of eating the material, the moisture of eating the material constantly evaporates, lead to eating the material water content and reduce, and then the viscosity that leads to eating the material increases, at this moment, the second operating parameter of motor can't drive the agitator and carry out abundant stirring to eating the material, consequently, when the current weight of eating the material and the ratio of initial weight drop to the second default, the control motor is with the third parameter operation, also carry out corresponding adjustment according to the viscosity of eating the material to the rotation of agitator, in order to guarantee the stirring effect.

In any of the above technical solutions, further, the third operation parameter includes a third rotation speed and a third torque of the electric machine; the third rotation speed is less than the second rotation speed, and the third torque is greater than the second torque.

In the technical scheme, when the specific gravity of the food material in the cooking appliance and the initial food material is larger than the first preset value of the motor, the motor operates with the first operation parameter at the moment, namely the motor is controlled to rotate at the first rotating speed and the first torque, the cooking is just started, the evaporation of water in the food material is less, the viscosity of the food material is the lowest, the requirement of the motor on the torque is lower, the stirring effect of the food material can be guaranteed through quick rotation, and the uniform stirring of various materials in the food material is guaranteed.

Further, when the ratio of the current weight of the food material in the cooking appliance to the weight of the initial food material is obtained, and is less than or equal to the second preset value and greater than the third preset value, it is indicated that moisture in the food material continues to evaporate, and the viscosity continues to increase, and at this time, the resistance of the food material to the stirrer further increases, so that in order to ensure that various materials in the food material can be uniformly stirred, the motor can be controlled to increase the torque, that is, the motor operates with the third torque greater than the second torque. Furthermore, due to the fact that the viscosity of the food materials is increased, in order to avoid the local clustering phenomenon of the food materials, the rotating speed of the motor is controlled to be reduced, and therefore the clustering phenomenon caused by the fact that the local motion of the food materials is too fast is avoided. That is, when the ratio of the current weight of the food material to the initial weight of the food material is less than or equal to the first preset value and greater than the second preset value, the motor is controlled to operate according to the third operating parameter, and the stirring effect of the food material is ensured.

In any of the above technical solutions, further, a value range of the third preset value is 0.75 to 0.73.

In the technical scheme, the value range of the third preset value can be limited according to different properties of food materials cooked by the cooking appliance and different requirements of a user on the cooking effect, specifically, the value range of the third preset value is 0.75-0.73, and the user can set the specific value of the third preset value according to the specific requirements of cooking so as to meet the requirements of the user.

Specifically, when making the sauce food, the third preset value may be set to 0.75, that is, when the ratio of the current weight to the initial weight of the sauce food in the cooking appliance decreases to 0.8 and does not decrease to 0.75, the cooking appliance controls the motor to increase the torque and decrease the rotation speed, so as to avoid the lumping while ensuring that the various cuts are uniformly stirred.

In any of the above technical solutions, further, the step of controlling the operation method of the motor according to the weight of the food material further includes: and controlling the motor to stop running based on that the ratio of the current weight of the food material to the initial weight of the food material is less than or equal to a third preset value.

In the technical scheme, the ratio of the weight of the current food material in the cooking appliance to the initial weight of the food material is obtained through the weight sensor arranged below the cooking cavity, the motor is controlled to run according to the ratio, and when the ratio of the weight of the food material in the cooking appliance to the initial weight of the food material is smaller than or equal to a third preset value, the motor stops running.

It can be understood that, when the ratio of the current weight of the food material in the cooking appliance to the initial weight is less than or equal to the third preset value, it indicates that the current water content of the food material has reached the cooking requirement, and if no food material is continuously stirred at this time, the evaporation speed of water in the food material can be accelerated, so when the weight ratio reaches the third preset value, the control motor stops operating, and the stirrer stops stirring the food material to ensure the cooking effect of the food material.

Specifically, when making sauced food, the third preset value is usually set to 0.75, that is, when the ratio of the current weight to the initial weight of the food in the cooking appliance reaches 0.75, the operation of the motor is stopped to avoid sauce drying.

In any of the above technical solutions, further, the cooking appliance further includes a heating device, the heating device is configured to heat the food material while the stirrer stirs the food material, and the control method further includes: and controlling the heating device to stop working based on the fact that the ratio of the current weight of the food material to the initial weight of the food material is less than or equal to a third preset value.

In the technical scheme, the ratio of the weight of the current food material in the cooking appliance to the initial weight of the food material is obtained through the weight sensor arranged below the cooking cavity, the motor is controlled to run according to the ratio, and when the ratio of the weight of the food material in the cooking appliance to the initial weight of the food material is smaller than or equal to a third preset value, the motor stops running. And meanwhile, controlling a heating device for heating the food material to stop running.

It can be understood that, when the ratio of the current weight of the food material in the cooking appliance to the initial weight is less than or equal to the third preset value, it indicates that the current water content of the food material has reached the cooking requirement, and if no food material is continuously heated, the evaporation speed of water in the food material can be accelerated, so that when the weight ratio reaches the third preset value, the heating device is controlled to stop running, the water in the food material is prevented from evaporating too fast, and the cooking effect of the food material is ensured.

In any of the above technical solutions, further, the motor includes a stepping motor, and the operation parameter includes a pulse frequency and a current value of the stepping motor.

In the technical scheme, the motor comprises a stepping motor, the pulse frequency of the stepping motor is in direct proportion to the rotating speed, therefore, under the condition that the number of teeth of the rotor and the running beat number are fixed, the rotating speed of the motor can be controlled by controlling the pulse frequency, the current value is in direct proportion to the torque of the motor, and under the current of normal work of the motor, the larger the current is, the larger the torque of the motor is.

Specifically, when the motor operates at the first operating parameter, the viscosity of the food material is relatively low and the weight of the food material is relatively large because the moisture of the food material in the cooking cavity is not sufficiently evaporated, and the rotating speed of the motor needs to be increased, correspondingly, the pulse frequency of the motor needs to be increased to increase the rotating speed of the motor and reduce the current of the motor to reduce the torque of the motor, when the motor operates at the second operating parameter, the viscosity of the food material is gradually increased because the moisture of the food material in the cooking cavity is evaporated, at this time, the weight of the food material is smaller than the weight of the food material under the first operating parameter, the viscosity of the food material is larger than the viscosity of the food material under the first operating state, at this time, the pulse frequency of the motor needs to be reduced to reduce the rotating speed of the motor and increase the current to increase the torque of the motor, when the motor operates at the third operating parameter, the moisture of the food material in the cooking cavity is further increased, the viscosity of the food material is further increased, at this time, the weight of the food material is smaller than the weight of the food material in the second operation state, and the viscosity of the food material is greater than the viscosity of the food material in the second operation state, so that the pulse frequency of the motor needs to be further reduced to reduce the rotating speed of the motor, and meanwhile, the current is increased to increase the torque of the motor.

Furthermore, the adjusting method of the rotating speed and the torque of the motor is adjusted in the normal working range of the motor, and when the load is overlarge, the motor is out of step due to insufficient torque of the motor.

Furthermore, the rotating speed and the torque of the motor are adjusted by controlling the pulse frequency and the current of the motor, so that the rotating speed and the torque can be adjusted correspondingly by the motor when the cooking appliance runs to each preset value in the running process, and the effect of cooking food materials by the cooking appliance is ensured.

A second aspect of the present invention provides a control apparatus of a cooking appliance, including: an acquisition unit for acquiring the weight of food material in the cooking appliance; and the control unit is used for controlling the operation parameters of the motor according to the weight of the food material.
