The cooking apparatus 100 according to the utility model embodiment is described below with reference to Fig. 1-Fig. 4, cooking apparatus here
100 can be electric cooker, electric pressure cooking saucepan, electric cooking pot etc..
As Figure 1-Figure 4, the cooking apparatus 100 of one embodiment according to the present utility model includes: pot body 10, lid
20, vacuum plant 40, current detector (not specifically illustrated in figure) and control device 50.
Pot body 10 limits upper surface (uper side surface as shown in Figure 2) open cooking cavity 11.Lid 20 is pivotly
It is connected in pot body 10, and movable to close or open cooking cavity 11 between a closed position and a open position.It is set on lid 20
There are bleeding point 21 and exhaust outlet 22, exhaust outlet 22 is connected to bleeding point 21.
Wherein, vacuum plant 40 is located in lid 20, and vacuum plant 40 is connected to bleeding point 21 and exhaust outlet 22 respectively, very
Empty device 40 is by vacuumizing cooking cavity 11, so as to form negative pressure, when needing to be evacuated, vacuum plant 40 in cooking cavity 11
The gas in cooking cavity 11 is extracted from bleeding point 21, and is discharged outside cooking cavity 11 by exhaust outlet 22.Current detector is to examine
Survey the operating current of vacuum plant 40.Control device 50 is connected with vacuum plant 40 and current detector respectively, control device 50
According to operating current obtain cooking cavity 11 in negative pressure pressure, and according to the negative pressure pressure in cooking cavity 11 to vacuum plant 40 into
Row control.In one embodiment of the utility model, control device 50 can be the electric-controlled plate of cooking apparatus 100.
Specifically, when vacuum plant 40 extracts the gas in cooking cavity 11 from bleeding point 21, load condition, control are in
Device 50 detects current variation value at this time, when the gas in cooking cavity 11 is constantly reduced, vacuum holding by current detector
It sets 40 load to change, the current value of current detector detection can also change.Control device 50 is according to current value pair
Storing data in control device 50 should be searched, and (record has vacuum degree (negative pressure pressure) and the corresponding of operating current to close in storing data
System), it can determine whether the vacuum degree in cooking cavity 11 at this time.Wherein, vacuum degree refers to the gas rarefied content under vacuum state,
Negative pressure pressure is bigger, shows that vacuum degree is higher, and vacuum degree is higher, shows that the pressure in cooking cavity is smaller.Due in cooking cavity 11
Gas be constantly pumped, vacuum degree gradually rises, and the pressure in cooking cavity 11 gradually decreases, by the judgement to vacuum degree,
Control whether vacuum plant 40 works on, for example, show that gas is very thin, controllably when vacuum degree reaches certain threshold value
Vacuum plant 40 processed stops working.
The cooking apparatus of the utility model as a result, using the operating current of current detector detection vacuum plant, and according to

Table 1 can obtain curve graph as shown in Figure 5.By table 1 and Fig. 5 it is found that when vacuum plant 40 extracts the gas in cooking cavity 11,
In load condition, current detector detects current value, when the gas in cooking cavity 11 is constantly reduced, vacuum plant 40 at this time
Load change, current detector detection current value can also change.I1-I9 value shown in Fig. 5 becomes larger,
The absolute value of negative pressure pressure P1-P9 gradually increases, and adds water to 10 graduation mark positions for example, adding in cooking cavity, the t1 moment is corresponding
I1 is 117mA, and P1 0KPa, t2 moment corresponding I2 is 120mA, and P2 is -5KPa ..., and so on.
In one embodiment of the utility model, negative pressure pressure follow operating current in cooking cavity 11 becomes larger and subtracts
It is small, and when operating current reaches predetermined current, the reduction of the negative pressure pressure follow operating current in cooking cavity 11 and reduce.Its
In, predetermined current can be demarcated according to the actual situation.
For example, as shown in table 1, gradually increasing with vacuum degree, after the operating current of vacuum plant 40 first becomes larger
Become smaller, for example, operating current becomes larger before negative pressure pressure is -20KPa, after negative pressure pressure -20KPa, work electricity
Stream is gradually reduced.Alternatively, as shown in figure 5, corresponding operating current I4 is maximum value when the time reaching t5.It is understood that
It is that negative pressure pressure is gradually reduced, shows that vacuum degree gradually increases.
