In the present embodiment, described food processor is provided with instant heating cavity, and the water of described water tank enters crushing chamber by instant heating chamber, knows the volume Vm of water in the described crushing chamber of injection by detecting the change of the instant heating intracavity water yield。The total capacity in described instant heating chamber is Vs, and described instant heating chamber is provided with multistage water level detecting device, and the water yield volume between adjacent two condensate tank of dehumidifier is definite value V。Again to water filling in described crushing chamber after the water of described instant heating intracavity injection Vs volume, when making material and water mixed volume in described crushing chamber reach setting capacity Vd, detect described instant heating intracavity water level when being in m section condensate tank of dehumidifier, now, injecting the water yield in described crushing chamber is Vm=Vs-mV+V/2。The change of the instant heating cavity water yield is determined by detecting water level in different periods instant heating cavity, and then determine in instant heating cavity, be injected in crushing chamber the water yield, it is injected in crushing chamber the water yield obtains current material amount deducting instant heating chamber according to material in crushing chamber and water inventory
In the present embodiment, instant heating intracavity water level detecting can realize by arranging multistage level electrode mode, and crushing chamber material and water inventory can pass through to be arranged in crushing chamber detecting electrode realizes。Instant heating intracavity arranges multistage level electrode and carries out signal detection, wherein carrying out number consecutively the most from low to high is 1,2 n, arranging the water yield volume between each level electrode is definite value V, volume between designated water level electrode 1 to level electrode n is Vs, then Vs=V* (n-1), according to practical situation, when level electrode number is very few, accuracy of detection is difficult to ensure that, so level electrode number can not be very few。As shown in Figure 1, instant heating intracavity is intake to level electrode n, that is the water of rated capacity is injected in instant heating chamber, then again to water filling in described crushing chamber, now, instant heating intracavity water then can be reduced to level electrode 1 by level electrode n, in crushing chamber the injecting process, water level capacity in detection crushing chamber simultaneously, that is, material and water mixed volume in detection crushing chamber, if in the injecting process, detect that the material in crushing chamber mixes with water to reach to set capacity Vd, then stop water inlet, and judge current instant heating intracavity water electrode signal, detect that current instant heating intracavity water level exceedes water level motor x and lower than level electrode x+1, the water yield then currently injected in crushing chamber is Vm=(n-x-1) * V+V/2, i.e. Vm=Vs-xV+V/2。And current capacities is Vd in crushing chamber, therefore, the volume of the material in crushing chamber is Vo=Vd-Vm。When calculating Vm, increasing V/2 is to reduce the deviation measured when water level is between two sections of water levels, and therefore, the hop count that level electrode is arranged is more many, and accuracy during for detection is more high。
In the present embodiment, the capacity set in crushing chamber is as 300ml, instant heating intracavity arranges 5 sections of level electrodes, between every section, volume is 50ml, the cumulative volume in instant heating chamber is 200ml, when instant heating intracavity is to crushing chamber injection value set volume 300ml, detection instant heating cavity in water level motor more than the 2nd section lower than low 3 sections, the water yield then currently injected in crushing chamber is Vm=125ml, then the inventory Vo=175ml in current crushing chamber。
In the present embodiment, the specified inventory of described food processor is Ve, and described food processor is according to the working procedure corresponding with the relation adjustment between specified inventory Ve of the inventory Vo in described crushing chamber。The working procedure of described food processor includes the water filling heating period, in the water filling heating period, as Vo > 2Ve, described food processor reminding alarm, user is reminded to take out partial material, otherwise material cannot effectively be pulverized by food processor, say, that food processor cannot normally complete making food。
The working procedure of described food processor includes by motor, the material in described crushing chamber being pulverized, the working procedure of described food processor includes by motor, the material in described crushing chamber being pulverized, and described food processor adjusts the rotating speed of described motor work and the time of motor work according to the inventory Vo in described crushing chamber and the relation between specified inventory Ve。During the inventory Vo in described crushing chamber≤specified inventory Ve, the rotating speed of described motor work is R=r, and the time of motor work is T=t。And when the inventory detected is too much, can suitably reduce motor speed, it is to avoid and the problems such as motor temperature rise are caused owing to load is excessive, simultaneously unaffected in order to ensure crushing effect, can suitably increase grinding time。Described food processor be provided with motor speed regulation coefficient Δ r, and motor working time regulation coefficient Δ t, during Ve < Vo < 2Ve, the rotating speed of described motor work is R=r-Δ r (Vo/Ve-1), time T=t+ Δ t (Vo/Ve-1) of motor work。The rotating speed of described motor work includes the slow-speed of revolution, two stages of high rotating speed。In described motor working time T, the described motor repeatedly intermittence that works is operated。The described slow-revving range of speeds is 1000 go to 10000 turns, and the described high-revolving range of speeds is 12000 go to 50000 turns。Shredding stage is divided into two stages according to motor speed, slow-speed of revolution shredding stage and high rotating speed shredding stage, generally, cause power of motor splash big, easy and noise excessive in order to avoid material uses high rotating speed to pulverize when whole granule original state, therefore, high rotating speed arranges slow-revving precomminution before pulverizing。Meanwhile, for ensureing the abundant pulverizing of material, in the batch process of described motor work, material in described crushing chamber is heated by described food processor。
Material is carried out the infusion stage of infusion by the working procedure of described food processor, and described food processor adjusts operating power and the working time in described infusion stage according to the inventory Vo in described crushing chamber and the relation between specified inventory Ve。As the inventory Vo in described crushing chamber≤specified inventory Ve, described infusion power is Q=q, the time of infusion is T1=t1, described food processor be provided with infusion power regulation factor Δ q, and infusion working time regulation coefficient Δ t1, during Ve < Vo < 2Ve, the rotating speed of described motor work is Q=q-Δ q (Vo/Ve-1), time T1=t1+ Δ t1 (Vo/Ve-1) of motor work。
In the present embodiment, concrete flow process is as in figure 2 it is shown, detection user puts into inventory Vo, it is judged that whether current material amount is more than VEmax, VEmax=2Ve, when exceeding, then quit work flow process, and reminds user to take out material, in order to avoid too much material causes motor blocking to affect positive pole safety, user now can take out partial material, and machine continues to judge inventory according to material detection scheme it is known that the inventory Vo of detection is less than VEmax；Now continuing the relation judging between Vo and Ve, if during Vo≤Ve, food processor to being operated, if during Ve < Vo <, then adjusts workflow according to the relation of Vo/Ve according to normal flow process。
For the food processor adopting 13000 rotating motors, under normal workflow, the rotating speed that the motor slow-speed of revolution is pulverized is generally 6000 and goes to 10000 turns, the rotating speed that high rotating speed is pulverized is 13000 turns, motor speed regulation coefficient Δ r is 1000 turns, it is assumed that during Vo/Ve=1.1, when the rated speed that the slow-speed of revolution is pulverized is 6000 turns, the rotating speed that the slow-speed of revolution after then adjusting is pulverized is 5000 turns, and the rotating speed of high rotating speed shredding stage is 12000 turns。
In the present embodiment, described food processor is provided with the setting threshold value for water level detecting, compare with setting threshold value by detecting current detection value, judge current level position, set threshold value as Vth, the initial value of described threshold value Vth is a, food processor detects that when the first level electrode is triggered, currency is b, described decision threshold Vth ranges for (Vmin, Vmax), if Vmin is < b < Vmax, then Vth=b+V, if b is < Vmin, Vth=a, if or b > Vmax, Vth=a。
In the present embodiment, as shown in Figure 3, after food processor power-up initializing, setting the initial value of threshold value Vth as a, the water controlling water tank enters instant heating chamber, when the first level electrode detection in instant heating chamber is lower than when setting threshold value Vth, judge that current first level electrode is more than the first level electrode, because when being typically in arranging water level detecting in food processor, when level electrode is unsettled, then now level electrode detection is higher level。The current detection value now detecting current first level electrode is b, it is judged that whether current detection value b is in scope (Vmin, the Vmax) interval setting threshold value Vth, if, then Vth=b+ Δ V, if not in this interval range, then setting threshold value Vth is still initial value a。In the present embodiment, the initial setting threshold value a value of tap water is typically between 2 volts to 3 volts, for ensureing the reliability judged, it is necessary to current level electrode detection value b is carried out validity decision。Δ V is the tolerance factor set, if b is too high or too low, then it is assumed that illegal during the detection of b, does not now use currency to update decision threshold, increases tolerance factor, and its set point is generally between 0.5-1 volt。
Thus, during different quality, different for water conductivity, its detected value also can be different, and can be updated along with detection owing to setting threshold value so that water level detecting is more accurate, and then the detection of inflow is also more accurate, the material known is also inevitable accurate, and the control for material is then more intelligent。Additionally it also avoid due to impact on level electrode detection under the drying regime of instant heating chamber and after being immersed in water。
By when crushing chamber volume quantitative, identifying the water injected in crushing chamber, thus the inventory known in crushing chamber。And then making food processor can be adjusted working procedure according to inventory, it is ensured that food processor all can better complete preparation effect at different conditions。
Carry out self adaptation setting by the setting threshold value judged by level electrode, by actually detected process using currency be updated, while ensureing reliability, reduce the probability of erroneous judgement。
