Example one
A control method of a food processor is provided, an anti-overflow electrode and a fan are arranged in the food processor, and the food processing process of the food processor comprises an anti-overflow collision stage; as shown in fig. 1, the method may include S101-S102:

wherein, the foam removing waiting time length is as follows: the time length from the beginning of the slurry foam rising to meet the anti-overflow electrode to the end of the slurry foam falling to be separated from the anti-overflow electrode.
In the embodiment of the invention, the starting and the rotating speed of the fan are controlled by the foam retreating waiting time of the collision prevention stage and the temperature of the slurry in the food processing process, so that the control on the height of the slurry and the foam is realized, and the overflow phenomenon in the food processing process is reduced.
In an embodiment of the present invention, the collision prevention stage may be a period in which the slurry foam frequently contacts the anti-overflow electrode after the slurry foam is generated, for example, the number of times that the slurry foam contacts the anti-overflow electrode is greater than or equal to a preset number threshold within a preset time, and it may be determined that the collision prevention stage is entered.
In the embodiment of the invention, the determination of the collision prevention stage can also adopt other modes, and any stage in which the slurry foam frequently contacts the anti-overflow electrode can be determined as the collision prevention stage.
In an embodiment of the invention, the fan may be arranged between the housing of the food processor and the blender cup and blow air to the outer sidewall of the blender cup after the fan is activated, in particular, may blow air to the upper half or the whole of the outer sidewall. The selection, number, specific installation position and installation mode of the fan are not limited, and the fan can be defined according to different application scenes or requirements.
Example two

Optionally, the controlling the start, the stop, and the rotation speed of the fan according to the foam removing waiting time and/or the slurry temperature may include:
and when the foam removing waiting time is longer than or equal to a first preset time threshold, starting the fan.
In the embodiment of the invention, if the foam withdrawal waiting time is too long, the current pulp foam is not easy to be withdrawn, and through the scheme of the embodiment, the pulp foam can be ensured to be withdrawn quickly, and the overflow risk is avoided.
Optionally, the controlling the start, the stop, and the rotation speed of the fan according to the foam removing waiting time and/or the slurry temperature may further include:
and when the temperature of the slurry is greater than or equal to a preset temperature threshold value, starting the fan.
In the embodiment of the invention, when the temperature of the slurry is too high and reaches a certain temperature value, the risk of slurry overflow is very high, and through the scheme of the embodiment, the fan can be started before the temperature of the slurry is too high, so that the air flow speed in the cup body is increased, the slurry foam is separated from the anti-overflow electrode, and the overflow risk is effectively avoided.
EXAMPLE III
This example provides an implementation of controlling fan start-up and speed in conjunction with the de-foaming wait period and slurry temperature based on example one.
Optionally, the controlling the start, the stop, and the rotation speed of the fan according to the foam removing waiting time and/or the slurry temperature may further include:
when the foam removing waiting time is less than a second preset time threshold and the temperature of the slurry is greater than or equal to a first preset temperature threshold T1, starting the fan and controlling the fan to work at a first preset rotating speed M1;
when the foam removing waiting time is greater than or equal to the second preset time threshold and the slurry temperature is greater than or equal to the first preset temperature threshold T1, starting the fan and controlling the fan to work at a second preset rotating speed M2;
wherein the second preset rotation speed M2 is greater than the first preset rotation speed M1.

In the embodiment of the invention, when the collision prevention stage is started, the fan may operate at the third preset rotation speed M3.
In the embodiment of the invention, in order to ensure the boiling degree of the slurry, the collision prevention stage adopts the relatively low rotating speed M3 of the fan to work, so that the temperature of the slurry can be slowly increased to the collision prevention level, and the integral temperature level in the subsequent pulping process is ensured, thereby indirectly ensuring the noise level in the pulping process.
In the embodiment of the present invention, the second preset duration threshold may be the same as or different from the first preset duration threshold, and the cell number is not limited.
In this embodiment of the present invention, the second preset duration threshold and the first preset duration threshold may include: 3-5 s; here 4s may be chosen.
In the embodiment of the invention, if the collision prevention back foam waiting time T is less than 4s and the temperature of the slurry is detected to be higher than T1, the fan can be started and operated at the rotating speed M1, and the fan is turned off when the temperature of the slurry is lower than the set temperature T2.
In the embodiment of the invention, if the foam-falling waiting time T is more than or equal to 4s after collision prevention and the temperature of the slurry is detected to be higher than T1, the fan can be started and the fan can work at the rotating speed M2.
In the embodiment of the present invention, M2 may be set to M1+ Δ M, where Δ M is a lift rotation speed, and a value range of Δ M may include: 1000-.
In the embodiment of the invention, the foam-withdrawing waiting time of the collision prevention is less than 3s under the normal condition, but the foam-withdrawing waiting time is prolonged due to the influence of other factors such as material types, for example, if the temperature during the collision prevention just meets the fan starting condition, the height of the foam is still high, the foam-withdrawing time is prolonged, which means that the rotating speed of the fan needs to be further increased, so that the height of the foam can be reduced, and the overflow risk is reduced.
In the embodiment of the invention, through the scheme of the embodiment, the starting of the fan is controlled by integrating the foam removing time and the size of the slurry temperature, and the rotating speed of the fan is correspondingly controlled, so that the slurry overflow caused by overhigh slurry temperature can be avoided.
Example four
This example provides an implementation of controlling fan start-up and speed by combining a longer demisting wait period than a re-contact spill electrode condition based on any of the examples described above.
Optionally, the method may further include:
when the foam removing waiting time is less than the second preset time threshold and the slurry foam collides with the anti-overflow electrode again, starting the fan and controlling the fan to work at the first preset rotating speed M1;
and when the foam returning waiting time is greater than or equal to the second preset time threshold and the slurry foam collides with the anti-overflow electrode again, starting the fan and controlling the fan to work at the second preset rotating speed M2.
In the embodiment of the invention, through the scheme of the embodiment, the starting of the fan is controlled by combining the condition that the foam removing waiting time is longer than the condition that the anti-overflow electrode is contacted again, and the rotating speed of the fan is correspondingly controlled, so that the pulp foam is ensured to fall and separate from the anti-overflow electrode, and the overflow of the pulp liquid is effectively avoided.
EXAMPLE five
This embodiment gives an implementation of controlling the stop of the fan on the basis of any of the above embodiments.
Optionally, the controlling the start, the stop, and the rotation speed of the fan according to the foam removing waiting time and the slurry temperature may further include:
when the slurry temperature is less than or equal to a second preset temperature threshold T2, turning off the fan; the second preset temperature threshold T2 is smaller than the first preset temperature threshold T1.
In the embodiment of the invention, because the slurry overflowing phenomenon can not happen generally when the temperature of the slurry is lower, the power consumption of the food processor can be saved and the food processing effect can be ensured by the scheme of the embodiment.
EXAMPLE six
The embodiment provides an anti-overflow implementation mode of other processing stages in the food processing process on the basis of any embodiment.
Optionally, the food processing process may further comprise: a preheating stage, a pre-slurry stirring stage, a concentrated crushing stage and a boiling stage;
the method may further comprise: and in the preheating stage, the pre-stirring stage, the concentrated crushing stage and the boiling stage, controlling the starting, the stopping and the rotating speed of the fan according to the temperature of the slurry.
Optionally, the controlling the start-stop and the rotation speed of the fan according to the slurry temperature in the preheating stage, the pre-stirring stage, the centralized crushing stage and the cooking stage may include:
and when the slurry temperature is greater than or equal to the first preset temperature threshold T1, starting the fan, and controlling the fan to work at a first preset rotating speed M1.
Optionally, the method may further include:
in the pre-stirring stage, the concentrated crushing stage and the boiling stage, when the pulp foam contacts the anti-overflow electrode again, the fan is started, and the fan is controlled to work at a first preset rotating speed M1;
and when the slurry temperature is less than or equal to the second preset temperature threshold T2, turning off the fan.
In the embodiment of the present invention, in the preheating stage of the food processing process, when the temperature of the slurry is detected to be higher than the first preset temperature threshold T1, the fan may be turned on and operated at the first preset rotation speed M1.
In the embodiment of the invention, in the pre-slurry stirring stage, the concentrated crushing and boiling stage, when the temperature of the slurry is detected to be higher than a first preset temperature threshold value T1 or slurry foam is detected to touch an anti-overflow electrode, the fan can be started and operated at a rotating speed M1, and when the temperature of the slurry is lower than a second preset temperature threshold value T2, the fan can be stopped.
In the embodiment of the invention, since the slurry needs to be heated to a relatively high level for reducing noise, even if the slurry is not pre-crushed, some powdery particles on the surface of the material can form some large foams at the temperature, the surface concentration of the foams is low, even if the particles contact with the anti-overflow electrode, the generated anti-overflow signal is weak, the identification is difficult, and the heating cannot be turned off, the temperature of the slurry needs to be detected at the moment, and if the temperature is higher than the set temperature, the air cooling system is started, the fan is turned on, and partial heat is taken away, so that the rising of the slurry foam is inhibited.
In the embodiment of the invention, in the pre-stirring stage and the centralized crushing stage, the temperature of the slurry is reduced along with the work of the motor, so that proper compensation heating is needed to ensure the temperature of the slurry, meanwhile, the heating of the motor body can indirectly heat the slurry along with the increase of the working time of the motor, and in order to ensure that the temperature of the slurry is relatively balanced in the compensation heating process, the control of the rotating speed of the fan can be adopted to realize the balanced correction of the temperature of the slurry.
In the embodiment of the invention, because stable cooking power can not be realized under a plurality of conditions, the rotating speed of the fan is controlled by detecting the temperature of the serous fluid or an anti-overflow signal in the cooking stage, so that the serous fluid is ensured to be cooked at a high temperature and not to overflow in the cooking stage, and the taste of food is improved.
EXAMPLE seven
This embodiment is based on any of the above embodiments and provides a specific implementation manner of the first preset rotation speed M1 and the second preset rotation speed M2.
Optionally, the method may further include: setting the first preset rotation speed M1 and the second preset rotation speed M2 according to the first preset temperature threshold T1.
In the embodiment of the present invention, when the first preset temperature threshold T1 satisfies: at 96-98 deg.c, for example, 97 deg.c, the first preset rotation speed M1 of the fan may be 1000-2000 rpm; when the first preset temperature threshold T1 is satisfied: 97-99 ℃, for example, when the temperature is 98 ℃, the first preset rotation speed M1 of the fan can work at 3000-4000 rpm; when the first predetermined temperature threshold T1 reaches 99 ℃ or higher, the first predetermined rotation speed M1 of the fan may be 5000-6000 rpm.
In the embodiment of the invention, the second preset rotating speed M2 of the fan can adopt 0-1000rpm in the collision prevention stage.
In an embodiment of the present invention, during the pre-slurry-stirring stage, the collective pulverizing and the cooking stage, when the temperature is detected to satisfy less than or equal to a second preset temperature threshold T2, for example, 97 deg.C or less, the fan may be turned off.
In the embodiment of the present invention, the second preset temperature threshold T2 may satisfy: 92-97 ℃.
In the embodiment of the invention, when the slurry temperature reaches 97 ℃, the fan rotation speed M1 can adopt 1000-. On the contrary, when the temperature of the slurry is lower than 97 ℃ in the pulping process, the fan can be turned off to reduce the heat loss, the heat loss level of the slurry can be controlled by controlling the rotating speed of the fan, so that the temperature level of the whole slurry is maintained, and the risk of overflowing does not exist in other temperature sections, so that the fan does not need to be turned on.
Example eight
This embodiment provides a specific implementation manner of controlling the start and stop of the fan according to the maintaining time of the slurry temperature at the current slurry temperature based on any of the above embodiments.
Optionally, the method may further include: and after the slurry temperature is detected, detecting the maintaining time of the slurry temperature, and controlling the starting, the stopping and the rotating speed of the fan according to the slurry temperature when the maintaining time meets the requirement of preset time.
In the embodiment of the invention, the fan can be started or stopped when the maintaining time period t satisfies 3s ≦ t1 ≦ 5s, for example, the fan can be started when the maintaining time period t satisfies 3s ≦ t1 ≦ 5s in a state that the temperature of the slurry is greater than or equal to 97 ℃. The fan can be stopped when the maintaining time t is longer than or equal to 3s, shorter than or equal to t1 and shorter than or equal to 5s under the condition that the temperature of the slurry is lower than 97 ℃.
In the embodiment of the invention, the frequent turning on or off of the fan caused by the fluctuation of the temperature of the slurry is avoided, and the turning on or off of the fan can be effectively avoided by adding the control of the time maintaining duration.
In the embodiment of the present invention, if t <3s, the influence on the slurry temperature fluctuation range is small, the frequency of turning on or off the fan is still somewhat large, and if t >5s, the slurry temperature may rise in a large range within 5s, and at this time, turning on the fan again may not effectively suppress the slurry temperature.
