Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the schematic diagram of the utility model food processor.
Specific embodiment
In order to be more clearly understood that above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the accompanying drawings and tool
Body implementation method is further described in detail to the utility model.It should be noted that in the case where not conflicting, this Shen
Feature in embodiment please and embodiment can be mutually combined.
Many details are elaborated in the following description in order to fully understand the utility model, but, this practicality
It is new to be different from other modes described here using other to implement, therefore, protection domain of the present utility model is simultaneously
Do not limited by following public specific embodiment.
As shown in figure 1, a kind of food processor, including for holding the cup 1 of pulping materials and water, in cup 1
Heater 2 that pulping materials and water are heated, the reducing mechanism 3 crushed to the pulping materials in cup 1, drive powder
The motor 4 of crushing device 3, and control heater 2 and the control device 5 of the work of motor 4.In the present embodiment, motor 4, crushing
Device 3, control device 5 etc. are all located in the head 7 of the top of cup 1.Wherein, reducing mechanism 3 is Disintegrating knife, certainly, may be used also
Crushed with using lapping device, in addition, motor, reducing mechanism, control device etc. can also be arranged on cup, and cup
Top then sets cup lid.Heater 2 is electrothermal tube and is welded on the bottom of cup 1, and certainly, electrothermal tube can also be welded on cup
Side, or can also be using other mode of heatings such as Electromagnetic Heating, steam heating, infrared heatings.It is emphasized that this reality
It is concerned with how to detect motor overload situation, and timely adjustment motor speed by automatically controlled mode with new, and then prevents motor mistake
The damage that height temperate zone is come is carried, therefore, for the protection of motor, reducing mechanism, heater, control device etc. in food processor
Scope is not limited by above-mentioned implementation method.
Food processor also includes the overload detector 6 of the detection overload of motor 4, overload detector 6 and control device 5
Electrical connection, after overload detector 6 detects the overload of motor 4, the reduction rotating speed of 5 controlled motor of control device 4, and then reduce motor
Workload, prevents motor overheating, while under relatively low rotating speed, the food such as food processor can still be completed to crush, heated
Processing technology.In addition, for the thinless problem of crushing for preventing the slow-speed of revolution from may bring, can also by extending grinding time,
Or solved by crushing the modes such as rear end setting rotating speed smart shredding stage higher in early stage.
Further, the motor that overload detector is detected in motor overload, i.e. the present embodiment for 6 continuous 2 times is in the rank
Section has two grades of rotating speeds, during start-up operation, in order to improve pulping efficiency using rotating speed high, during overload, reduces rotating speed and uses low turn
Speed protection motor, on the other hand, is worked by previous motor 4 and material is crushed, when reducing motor work next time
Load.In the case of such as being worked using the slow-speed of revolution, motor still overloads, then the controlled motor 4 of control device 5 stalls and controls to add
Thermal 2 is heated and softened to the pulping materials in cup 1, further reduces motor load.Certainly, motor can also be in the stage
With more than two grades rotating speeds, the control protection to motor further becomes more meticulous.In general, the controlled motor 4 of control device 5 is reduced
Rotating speed be not less than 1000 revs/min.The general rotating speed of motor used in food processor 6000-25000 revs/min it
Between, less than 6000 revs/min of motor can not meet crushing slurrying demand, and more than 25000 revs/min of motor is due to work
A series of problems, such as noise, radiating, is also not suitable with the application in food processor, with existing motor process, rotating speed between adjacent two grades
In the case of differing from the speed discrepancy less than 1000 revs/min because foozle is difficult to, and less than 1000 revs/min
Motor is relatively low to the sensitiveness for loading, i.e., motor reduces rotating speed, and load is not substantially reduced.Further, control dress
Put 5 controlled motors 4 stall and control heater 2 in cup 1 pulping materials heat and soften after, control device 5 controls electricity
Machine 4 starts to be crushed, and overload detector 6 detects motor 4 and overloads, then the controlled motor 4 of control device 5 is stalled and points out exception,
Such as point out user's inspection pulping materials whether excessive etc., prevent from further crushing slurrying damage motor.
It is noted that food processor also includes temperature-detecting device, general, temperature-detecting device is to be soaked in
Temperature sensor 8 in cup slurries, in the present embodiment, temperature sensor 8 is located at head lower section, naturally it is also possible to positioned at cup
Side wall on.Temperature sensor 8 is electrically connected with control device 5, and control device 5 controls heater 2 to the slurrying thing in cup 1
Material and water are heated until temperature sensor 8 detects the temperature of pulping materials and water in cup for more than 90 DEG C or seethes with excitement
Afterwards, controlled motor 2 drives reducing mechanism to crush the pulping materials in cup 1 to control device 5 again, and then enters to slurrying
The shredding stage of material.
For the deterministic process of motor overload, specifically have, the operating current that overload detector 6 detects motor 4 is big
In current threshold I, simultaneously duration threshold value t then judges motor overload.Compared with the prior art, if only single sentence with current threshold I
If disconnected overload, the performance of anti-external interference will be reduced, i.e., more easily determine overload with respect to present embodiment, or even occur only
It is larger immediate current, but the phenomenon that the duration is not grown, cause to protect by mistake, influence slurrying experience.Add in present embodiment
If the dimension of upper another duration threshold value t, can not only reduce the mistake that external interference causes and protect, can also by this section when
Between motor work material is crushed, reduce next time motor work when load.Preferably, current threshold I includes m grades
Current threshold I（1）-I（m）, current threshold I（k）Corresponding duration threshold value is t（k）, wherein, m is the natural number more than or equal to 2,
I（i）＞ I（i+1）, t（i）＜ t（i+1）, the operating current that overload detector 6 detects motor 2 meets any one group of electric current
Threshold value and duration threshold value then judge motor overload, meet the accurate protection to motor.Further, overload detector 6 is examined
The operating current for measuring motor 4 meets current threshold I（j）With duration threshold value t（j）Afterwards, control device controlled motor rotating speed reduction
ΔN（j）, wherein, Δ N（j）＞ Δs N（j+1）, that is, the current threshold I for breaking through（j）Bigger, it is more that rotating speed is lowered.
After food processor also includes that voltage check device 9, overload detector 6 detect the overload of motor 4, voltage detecting
When the operating voltage of the detection food processor of device 9 is V1, the rotating speed of the reduction of 5 controlled motor of control device 4 is Δ N1, voltage inspection
When the operating voltage for surveying the detection food processor of device 9 is V2, the rotating speed of the controlled motor of control device 5 reduction is Δ N2, V1 ＞
V2, then Δ N1 ＜ Δs N2.Operating current in view of motor under high voltage operating mode is big compared to low-voltage operating mode, in the situation of overload
Under, modulation is less than low-voltage operating mode under motor speed under high voltage operating mode, is conducive to ensureing crushing effect to greatest extent.
Certainly, those skilled in the art be appreciated that above content be only preferred embodiment of the present utility model and
, not it is all for limiting practical range of the present utility model, i.e., all impartial changes made according to the utility model and modification
The utility model right is covered, and no longer illustrates one by one here.
