It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a control method of a cooking apparatus according to an embodiment of the present disclosure.

In this embodiment, the cooking device can be an electric appliance such as a stirrer, a food processor, a juice machine, a coffee machine, etc. which needs a motor to rotate and stir. The cooking device adopts the motor drive processing subassembly to process the edible material, like the agitator, the drive shaft and the processing subassembly of motor are connected for it is rotatory to drive the processing subassembly under the drive of motor, in order to accomplish the processing of edible material.

The inventor of the application finds that the detection of the food material amount borne by the cooking device in the industry at present is generally carried out by adopting the modes of a weighing sensor, a liquid level detection sensor and the like, and the defects of the mode are that the complexity of the structural part of the cooking device is increased, the manufacturing difficulty is increased, and the integral manufacturing cost is higher.

Based on this, the present embodiment provides a method for determining the amount of food material in a cooking device, specifically, as shown in fig. 1, the method includes the following steps:

step S10: and receiving an operation instruction, and selecting a corresponding functional key of the cooking device according to the operation instruction.

The integrated household appliance with the compressed space can effectively solve the use pain of small and medium-sized families, and can avoid the embarrassment that household appliances are bought in high loft due to space limitation and single function when being bought home. The cooking device is more and more integrated, has multiple functions, integrates the functions of making soybean milk, grinding dry powder, squeezing fruit juice, making meat stuffing, shaving ice and the like, and is used for making various foods such as fruit juice, soybean milk, jam, dry powder, shaving ice, meat stuffing and the like. Therefore, when the cooking device is started, the function selection is firstly required, that is, one function key of the cooking device is selected, and the operation is generally performed by the user.

Step S20: the method comprises the steps of controlling the motor to operate at preset power, and obtaining a first operation parameter of the motor under the preset power.

In this embodiment, the preset power may refer to an average power, or may be a total power of a preset time. The motor is controlled to operate at the preset power, so that the input power is the same when the food material quantity in the cooking device is detected every time, and the detection accuracy is further ensured.

Optionally, the motor is controlled to operate at a preset power for a preset time, and the preset time can ensure that a result of each detection of the food material amount is obtained, and can ensure that the time is not too long, so that the user experience is reduced.

Optionally, this example can control this preset power at certain interval within range, can avoid when detecting edible material quantity, and motor speed is too big, brings the unnecessary noise, and perhaps motor speed undersize, the stifled commentaries on classics phenomenon appears in the motor.

Step S30: and determining the food material quantity according to the first operation parameter.

The amount of the food material in this embodiment may refer to the weight of the food material, or may be the number of the food material.

Optionally, in this embodiment, a semiconductor switch is disposed in the current loop of the motor, and the delay time of the semiconductor switch is adjusted to control the motor to operate at the preset power.

The semiconductor switch can be a silicon controlled switch, and can be a unidirectional silicon controlled switch or a bidirectional silicon controlled switch. The silicon controlled switch mainly has the following two modes, namely a wave-dropping control mode and a chopping control mode, and the two modes can enable the silicon controlled switch to realize the adjustment control of the load power.

The operating principle of the silicon controlled switch is that the on-off time ratio of the alternating current power supply is controlled by controlling the conduction angle of the silicon controlled switch. In fact, the larger the conduction angle of the thyristor switch is, the longer the delay time of the thyristor switch is, the smaller the on-off time ratio of the alternating current power supply is, and the smaller the preset power corresponding to the conduction angle is. For example, the conduction angle of the thyristor switch may be 20 °, 30 ° or 40 °. By controlling the size of the conduction angle, a preset power corresponding to the conduction angle can be determined. Of course, the conduction angle of the thyristor switch may be any other angle, and is not limited in detail herein.

In a specific application scenario, the first operating parameter of the motor is a first rotating speed of the motor, that is, the first rotating speed of the motor under the preset power is obtained. The first rotating speed of the motor spindle is directly obtained through a rotating speed sensor, such as a hall sensor, a rotating speed coding code disc or an infrared speed measuring sensor.

Referring to fig. 2, fig. 2 is a schematic flowchart of an embodiment of step S30 in fig. 1, and as shown in fig. 2, step S30 may include:

step S31: and a lookup table of the corresponding relation between the motor rotating speed and the food material quantity borne by the cooking device is established in advance. The lookup table comprises a plurality of rotating speeds of the motor and a plurality of food material amounts in one-to-one correspondence with the rotating speeds of the motor.

In fact, at a certain preset power, the rotation speed of the motor is in inverse proportion to the amount of food materials that can be carried by the cooking device. For example, the relationship between the motor speed and the amount of food material that can be carried by the cooking device can be expressed by the following formula: -kx ═ y

Wherein y represents the motor speed, x represents the amount of food material that can be carried by the cooking device, k represents a coefficient, and k > 0.

In other words, the greater the amount of food material carried by the cooking device, the slower the motor speed, and the smaller the amount of food material carried by the cooking device, the faster the motor speed.

Considering that the rotation speed of the motor at each moment in the preset operation time may be unstable, the present embodiment may obtain the average rotation speed of the motor in the preset operation time as the first rotation speed of the motor.

Alternatively, a lookup table of the correspondence relationship between the motor rotation speed and the food material amount is established in advance by an experimental manner, and the lookup table is stored in a memory of the cooking apparatus for standby.

Optionally, the lookup table may also be obtained by an external device, that is, the lookup table is in communication connection with the external device through bluetooth, a network, and the like, and receives the lookup table about the corresponding relationship between the motor rotation speed and the food material amount, which is sent by the external device.

Step S32: and matching the first rotating speed of the motor with the lookup table to obtain the food material amount corresponding to the first rotating speed of the motor.

Specifically, whether the query table contains a rotating speed value which is the same as the acquired first rotating speed or not is judged, if yes, the food material quantity corresponding to the rotating speed value is determined, and the food material quantity is determined to be the food material quantity loaded by the cooking device.

In a specific application scenario, the manner of obtaining the amount of food in the cooking device according to the present embodiment is described in detail by taking a thyristor as an example. Firstly, the conduction angle of the silicon controlled switch is controlled to be a preset angle, such as 30 degrees, so as to determine the preset power of the motor operation, and in addition, the operation time of the motor under the preset power can be preset, wherein a query table reflecting the corresponding relation between the food material quantity and the first rotating speed is stored in a memory of the cooking device. The method comprises the steps of receiving a function operation instruction, selecting a corresponding function key of a cooking device according to the function operation instruction, starting a motor under the preset power, obtaining a rotating speed value of the motor in real time, calculating an average rotating speed value of the motor according to the real-time rotating speed value of the motor when the motor runs, taking the average rotating speed value as a first rotating speed, matching the obtained first rotating speed with a lookup table reflecting the corresponding relation between the food material quantity and the first rotating speed, and determining the food material quantity corresponding to the first rotating speed.

In order to improve the accuracy of the food material amount detected by the cooking apparatus, in another embodiment, the first operating parameter of the motor may further include a current value of the motor, that is, a first rotation speed of the motor at a preset power at the same time and a current value of the motor are obtained.

In fact, at a certain preset power, the value of the current flowing through the motor is in direct proportion to the amount of the food material that can be carried by the cooking device. In other words, the greater the amount of food material carried by the cooking device, the greater the value of the current flowing through the motor, and the smaller the amount of food material carried by the cooking device, the smaller the value of the current flowing through the motor.

Alternatively, the current of the motor may be obtained by providing a current sampler in a current loop of the motor, and obtaining the current flowing through the motor by the current sampler. After the current flowing through the motor is acquired, the acquired current value flowing through the motor can be filtered to remove noise interference.

Similarly, in consideration of the fact that the current value of the motor at each moment in the preset operation time may be unstable, the present embodiment may obtain the average current value of the motor in the preset operation time as the current value flowing through the motor.

Referring to fig. 3, fig. 3 is a schematic flowchart of another embodiment of step S30 in fig. 1, and as shown in fig. 3, step S30 may include:

step S33: and establishing a lookup table of the corresponding relation between the rotating speed of the motor, the current value of the motor and the food material quantity borne by the cooking device.

The lookup table comprises a plurality of two-dimensional vectors formed by the rotating speeds of a plurality of motors and the current values of the plurality of motors, and the food material amount corresponding to each two-dimensional vector.

Alternatively, a lookup table of the correspondence between the motor rotation speed, the motor current value, and the food material amount is established in advance through an experimental manner, and the lookup table is stored in a memory of the cooking apparatus for standby. Alternatively, the motor rotation speed and the current value of the motor in the lookup table may be an average rotation speed and an average current value in the preset operation time.

Optionally, the lookup table may be obtained by an external device, that is, when the cooking tool is in operation, the cooking tool establishes a communication connection with the external device through bluetooth, a network, and the like, and receives the lookup table about the corresponding relationship between the motor rotation speed, the motor current value, and the food material amount, which is sent by the external device.

Step S34: and matching the first rotating speed of the motor and the current value of the motor with a pre-established lookup table to obtain the food material amount corresponding to the first rotating speed of the motor.

Optionally, it is determined whether the lookup table includes a rotation speed value identical to the acquired first rotation speed, if so, it is determined whether the lookup table includes a current value identical to the acquired current, and if so, the food material amount corresponding to the rotation speed value and the current value is determined, and the food material amount is determined as the food material amount loaded by the cooking apparatus.

According to the control method of the cooking device, the motor is controlled to operate at the preset power, the first operating parameter of the motor under the preset power is obtained, and the food material quantity is determined according to the first operating parameter.

The inventor of the application finds that the cooking device generally has a plurality of menu functions, each menu function corresponds to a group of parameters such as rotating speed, running time and the like, and when a user selects any menu function, the motor runs at the rotating speed, the running time and the like corresponding to the menu function until the menu function is completed or the motor is manually controlled to stop. This method has the disadvantage that when the material of the material to be whipped is different from the amount of the material to be whipped, the parameters such as the motor rotation speed may be different under the same function procedure, for example, when the material (such as carrot) with hard texture is whipped or the amount of the material is large, the motor rotation speed becomes lower, and even stalling may occur, so that the whipping time is prolonged, and the whipping effect is difficult to guarantee. When the food material with soft texture is stirred or the food material quantity is small, the motor continuously runs at a high speed, so that larger noise can be avoided, and the user experience is influenced.

Based on this, the inventor of the present application determines the operation parameters of the motor according to the determined amount of the food material carried by the cooking device, thereby avoiding the above-mentioned disadvantages. Specifically, after obtaining the amount of the food material carried by the cooking device, the method may further include the following steps:

step S40: and determining a second operation parameter of the motor according to the food material quantity.

Step S50: and adjusting the operation parameter of the motor to a second operation parameter.

In one embodiment, the second operating parameter is a second rotational speed of the electric machine. The second rotating speed is the rotating speed matched with the food material quantity borne by the cooking device.

The second rotating speed of the motor is in direct proportion to the food quantity. That is, the larger the determined food material amount is, the larger the rotation speed of the set motor is, and conversely, the smaller the rotation speed of the set motor is. Through this kind of mode, can avoid the motor when eating the material volume less, use with the great rotational speed operation of current function assorted, harmful effects such as noise big that probably cause, and when eating the material volume great, use with the less rotational speed operation of current function assorted, probably take place the stall to the whipping time can prolong, and the consequence that the whipping effect is poor.

Optionally, a correspondence table between the food material amount and the second operation parameter is obtained or established in advance. For example, to simplify the operation, the amount of food material may be divided into a plurality of levels according to size, each level corresponding to a second rotation speed. When the food material amount in the cooking device is determined, a second rotating speed corresponding to the food material amount is determined according to the grade of the food material amount, and then the current rotating speed of the motor is adjusted to the second rotating speed.

Optionally, the motor speed is adjusted to the second speed by the semiconductor switch.

The silicon controlled switch can regulate the speed of the motor, and after the food material amount in the current cooking device is determined, the power input to the motor is controlled by adjusting the conduction angle of the silicon controlled switch, and the rotating speed of the motor is adjusted to the second rotating speed.

In another specific embodiment, the second operating parameter is an operating time of the electric machine. The operating time of the motor is an operating time that matches the amount of food material carried by the cooking device.

In fact, the operation time of the motor is proportional to the amount of food material, and therefore, the operation time of the motor can be determined according to the amount of food material, i.e., the control operation time is longer as the amount of food material in the cooking device is larger, and conversely, the control operation time is shorter as the amount of food material in the cooking device is smaller.

It can be understood that, by establishing a correspondence table of the food material amount and the motor operation time in advance, after determining the food material amount, the operation time of the motor can be determined by matching the food material amount with the correspondence table.

In this embodiment, the operation time of the motor is not a fixed preset operation time corresponding to the menu function of the cooking apparatus, but an operation time corresponding to the operation time determined according to the amount of the food material in the cooking apparatus. In other words, the operation time of the motor, which is adapted to the amount of food in the cooking apparatus, may be greater than or less than a preset operation time preset in a specific menu function of the cooking apparatus. For example, when the amount of food material in the cooking apparatus is large, the operation time corresponding to the large amount of food material may be greater than the preset operation time corresponding to the menu function, whereas when the amount of food material in the cooking apparatus is small, the operation time corresponding to the small amount of food material may be less than the preset operation time corresponding to the menu function.

Through this kind of mode for motor operation time and motor load (promptly, eat material quantity) phase-match, can avoid because motor load is too big, predetermine the not good cooking device execution effect that causes inadequately of operation time, can prevent again that motor load undersize, predetermine the electric quantity waste that the operation time overlength caused.

To sum up, the cooking device that this embodiment provided adopts motor drive processing subassembly to process edible material, the control method of the cooking device that this application provided, through control motor with preset power operation, and acquire the first operating parameter of motor under preset power, eat material quantity according to first operating parameter determination, through this kind of mode, can utilize the parameter determination cooking device's of motor operation itself edible material quantity, can avoid traditional mode, utilize devices such as weighing sensor, liquid level detection sensor to detect edible material quantity promptly, the complete machine structure complexity that leads to increases, the manufacturing difficulty increases, and manufacturing cost increases. In addition, according to the scheme, the obtained food material quantity of the cooking device is utilized, the operation parameters of the motor are adjusted, the operation parameters of the motor of the cooking device can be matched with the actual load, the noise generated by the operation of the motor can be reduced, and the user experience is improved.
