Detailed Description
The following describes in detail embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
In the embodiments of the present invention, the use of directional terms such as "inner and outer" refers to the inner and outer of the corresponding profile, unless otherwise specified.
Fig. 1 is a schematic structural diagram of a whipping control device and a food processor according to an embodiment of the present invention. As shown in fig. 1, the food processor may include, for example: a stirring container 1 for placing food to be stirred; a whipping part 2 extended into the stirring container 1 for rotating to whip the food; and the stirring motor 3 is connected with the stirring piece 2 and is used for driving the stirring piece to rotate.
Referring to fig. 1, the whipping control device 4 of the embodiment of the present invention may include: a vibration detector 41, installed near the whipping motor 3, for detecting a vibration signal generated by the food processor due to the rotation of the whipping motor; and a controller 42 electrically connected to the vibration detector 41 and the whipping motor 3 (fig. 1 does not show the electrical connection relationship between the controller and the vibration detector and the whipping motor), for controlling the rotation speed of the whipping motor 3 according to the vibration intensity reflected by the vibration signal.
Wherein, stirred vessel 1, stir and beat 2 and beat motor 3 and be the conventional beating part of food processor, this food processor can be broken wall machine, soybean milk machine, stock machine, coffee machine etc. need the motor to rotate the electrical apparatus of beating.
The food processor of the embodiment of the invention can further comprise, on the basis of comprising the conventional whipping part: a body 5, and the whipping motor 3 is fixed in the body 5, and the vibration detector 4 is fixed on the body 5 and close to the whipping motor 3. In this manner, the whipping control device 4 of the embodiment of the present invention is integrated with the conventional whipping part through the body 5 to form a more fully functional food processor.
Furthermore, the stirring container 1 is installed on the outer side of the upper portion of the body 5, the stirring motor 3 is connected to the stirring member 2 through the motor shaft 6, and the stirring member 2 may be a blade which extends into the stirring container 1 to stir food. The vibration detector 41 is preferably installed at a position inside the upper portion of the body 5, the inside being closer to the whipping motor 3 than the outside.
In the embodiment of the present invention, the vibration detector 41 preferably employs an acceleration sensor, so that the corresponding vibration signal is a vibration acceleration, and the vibration acceleration can reflect the vibration strength relative to parameters such as vibration displacement. When the food processor starts a whipping function, the whole machine vibrates due to the rotation of the whipping motor, so that the acceleration sensor is driven to move, and the acceleration sensor can convert data (x, y and z) in three directions of an X axis, a Y axis and a Z axis in real time.
In other embodiments, the vibration detector 41 may be a sensor that detects signals such as vibration displacement, vibration speed, and vibration frequency, or may be a vibration meter that can directly detect and calculate the vibration intensity.
Fig. 2 is a schematic structural diagram of a controller according to an embodiment of the present invention. The controller 42 may be configured directly with the control components of the food processor itself, and the installation location is not limited by the embodiment of the present invention. Referring to fig. 2, the controller 42 may include: a signal processing module 421, configured to process the vibration signal to obtain a corresponding vibration intensity; and a motor control module 422 for controlling the rotation speed of the whipping motor 3 according to the vibration intensity.
The signal processing module 421 preferably reads the vibration signal from the vibration detector 41, for example, for the vibration acceleration, the signal processing module 421 first reads the data (x, y, z) converted by the acceleration sensor in real time, and then obtains a value reflecting the vibration intensity of the food processor through a certain filtering algorithm and an arithmetic algorithm, and the value is set as d. For example, the vibration acceleration signal is subjected to filter processing by a filter algorithm, and the product of the vibration acceleration and the displacement in the acceleration direction is calculated by an arithmetic algorithm, and the value represented by the product is the vibration intensity d.
Wherein the motor control module 422 is configured to control the rotation speed of the whipping motor according to the vibration intensity, and may comprise: when the vibration intensity is smaller than the preset minimum vibration intensity, increasing the rotating speed of the whipping motor; when the vibration intensity is larger than the preset maximum vibration intensity, reducing the rotating speed of the whipping motor; and the preset maximum vibration intensity is greater than the preset minimum vibration intensity.
For example, if the preset minimum vibration intensity is D1 and the preset maximum vibration intensity is D2, D2 is larger than D1, and the interval [ D1, D2] represents the vibration intensity range of the food whipping device when whipping under ideal conditions (the food material has moderate hardness, moderate viscosity, and moderate amount). If D is less than D1, it indicates that the material possibly being whipped is harder, more sticky or the amount of the whipped material is larger, so that the action of the whipping member is blocked, which means that the vibration intensity of the whole food whipping device is smaller, and therefore the rotation speed of the whipping motor should be increased to improve the whipping force; if D > D2, it indicates that the material may be stirred softer, thinner or less material, so that the stirring speed of the stirring member is too fast, which means that the vibration intensity of the whole food stirring device is greater, and therefore the rotation speed of the stirring motor should be reduced to reduce the stirring speed and prevent the nutritional ingredients in the material from being damaged due to too fast stirring.
Therefore, the data (x, y, z) of the acceleration sensor can be read once every time delta t, the vibration intensity D is obtained through processing of a filtering algorithm and an arithmetic algorithm, the rotating speed of the motor is adjusted according to the size of D relative to D1 and D2, and the operation is repeated for N times, so that the whipping effect can be guaranteed not to change due to different factors such as the material and the quantity of the whipped food until the whipping is finished. Where Δ t is preferably 5 ms to 2000 ms, but not limited to this range, and N is preferably 2 times or 3 times, but not limited thereto, and may be set by those skilled in the art according to actual requirements.
In summary, the whipping control device of the embodiment of the present invention implements an automatic whipping control strategy based on the vibration intensity caused by whipping, and can ensure that the whipping effect does not change due to different factors such as the material and amount of the whipped food material, thereby further ensuring the consistency of the whipping time and the whipping effect.

In a preferred embodiment, the food processor may further include: a stirring container 1 for placing food to be whipped; a whipping part 2 extending into the stirring container 1 for rotating to whip the food; the stirring motor 3 is connected with the stirring piece 2 and is used for driving the stirring piece 2 to rotate; and the whipping control means 4 described above.

Step S321, processing the vibration signal to obtain a corresponding vibration strength.
For example, the data (x, y, z) converted by the acceleration sensor in real time can be read first, and then the vibration intensity d reflecting the vibration intensity of the food processor can be obtained through a certain filtering algorithm and a certain calculation algorithm. The filtering algorithm can be configured to be executed by a conventional filter, and the calculation algorithm can be a product obtained by multiplying the vibration acceleration by the displacement in the acceleration direction, wherein the product is the vibration intensity d.
Step S322, controlling the rotation speed of the whipping motor according to the vibration intensity.
Preferably, the step S322 may further include: when the vibration intensity is smaller than the preset minimum vibration intensity, increasing the rotating speed of the whipping motor; when the vibration intensity is larger than the preset maximum vibration intensity, reducing the rotating speed of the whipping motor; and the preset maximum vibration intensity is greater than the preset minimum vibration intensity.
