Tracheae 13 enters shell 11, is discharged from the exhaust outlet of shell 11, realizes that the liner of electric steam box ontology 2 is quickly cooled down.
The shell 11 is cooperatively connected by upper housing 111 and lower case 112.
The sealing element outer of the proportioning valve 12 is conical surface shape, and sealing element is placed in exhaust pipe 13,
The opening size of the proportioning valve 12 is directly related by input current size.
The thermostatic control process of the utility model, as shown in figure 5, being realized by following steps:
Step 101: inner cavity temperature sensor 6 measures inner cavity observed temperature in real time；
Step 102: measuring the difference of inner cavity observed temperature in real time by preset cooking temp and inner cavity temperature sensor 6
With the comparison of threshold interval, the working condition of gas deflation assembly 1, cistern assembly 4 is determined.
Specifically, the difference of inner cavity observed temperature is measured in real time according to preset cooking temp and inner cavity temperature sensor 6
Adjust that discharge of steam amount is how many and how much is steam production, to realize the temperature controlled effect in inner cavity.
The size of control discharge of steam amount forms inner cavity exhaust passage opening size with exhaust pipe 13 by proportioning valve 12 and determines,
Wherein the opening size of inner cavity exhaust passage is directly related by the input current size of proportioning valve 12, can be by inputting different ratios
Example valve electric current makes the exhaust passage between the sealing element of proportioning valve 12 and inner cavity exhaust pipe realize the control of different opening；
The size of control steam production is determined by the liner volume of electric steam box ontology 2, heating tube watt level, water injection rate
Fixed, wherein the liner volume of electric steam box ontology 2, heating tube watt level are constant, therefore the size of steam production is mainly by infusing
The size of water determines that the size of water injection rate is mainly determined by water pump；
The proportioning valve 11 is closed valve state in no power, is valve opening state when inputting a constant current
Under certain heating power, required steam production is adjusted by controlling the water injection rate of water pump of cistern assembly 4.
When preset cooking temp and inner cavity temperature sensor 6 measure the difference of inner cavity observed temperature in first threshold in real time
When in section, the proportioning valve 12 and control cistern assembly 4 for closing exhaust gear 1 increase to the increasing water injection rate of steam generation component 3
The steam production of steam generation component 3 reduces steam exhaust-gas amount, realizes that the liner temperature of electric steam box ontology 2 increases；
When preset cooking temp and inner cavity temperature sensor 6 measure the difference of inner cavity observed temperature in second threshold in real time
When in section, maintains current cistern assembly 4 to the water injection rate of steam generation component 3 and open the increasing of proportioning valve 12 of exhaust gear 1
Add steam exhaust-gas amount, realizes that the liner temperature of electric steam box ontology 2 reduces.
The first threshold section is 3 DEG C of X >=0 DEG C >, and the second threshold section is -3 DEG C of 0 DEG C of < X <, and X is default
Cooking temp and inner cavity temperature sensor 6 measure the difference of inner cavity observed temperature in real time.
When opening the proportioning valve 12 of exhaust gear 1, the acceleration of cross flow fan 14 for opening the exhaust gear 1 passes through steam
By steam exhaust-gas amount.
By adjusting the aperture of the input current control proportioning valve 12 of the proportioning valve 12, the aperture of proportioning valve 12 controls electricity
The exhaust passage size of the liner of steam box ontology 2.
For example, as shown in fig. 6, S10: it detects preset cooking temp and surveys the size of the difference X of inner cavity temperature, if 3 DEG C
When X >=0 DEG C >, it is transferred to S12；If being transferred to S11 at -3 DEG C 0 DEG C of < X <；
S11: input electromagnetic switch valve electric current controls the aperture of proportioning valve 12, while maintaining water pump water injection rate is M, until
Complete culinary art duration；
S12: the electromagnetic switch valve no power of steam input pipe 5 is in close state, while being controlled and being increased water pump water filling
Amount is 1.5M, until completing culinary art duration；
S13: it shuts down after culinary art duration；
Assuming that preset cooking temp is 100 DEG C, actual measurement inner cavity temperature is 97.5 DEG C, when secondary culinary art pump-out water injection rate is
2ml/s。
S10: detecting preset cooking temp and surveys the size of the difference X of inner cavity temperature,
X=100-97.5=2.5 DEG C, meets 3 DEG C of X >=0 DEG C > conditions, be transferred to S12；
S12: electromagnetic switch valve no power is in close state, while being controlled and being increased suction pump water injection rate as 1.5M, that is, is infused
Water is 1.5x2ml/s=3ml/s, until completing culinary art duration；
S13: it shuts down after culinary art duration；
Assuming that preset cooking temp is 100 DEG C, actual measurement inner cavity temperature is 101 DEG C, when secondary culinary art pump-out water injection rate is
2ml/s。
S10: detecting preset cooking temp and surveys the size of the difference X of inner cavity temperature,
X=100-101=-1 DEG C, meets 0 DEG C of condition of -3 DEG C of < X <, be transferred to S11；
S12: input electromagnetic switch valve electric current controls ratio valve opening, while maintaining suction pump water injection rate is M, that is, is filled the water
Amount is 2ml/s, until completing culinary art duration；
S13: it shuts down after culinary art duration.
After step 102, if culinary art terminates, by controlling gas deflation assembly 1, cistern assembly 4, steam input pipe
The working condition on road 5 carries out the rapid cooling of the liner of electric steam box ontology 2.
Specifically, the water pump of the electromagnetic switch valve and cistern assembly 4 that control steam input pipe 5 is in close state, and is opened
The cross flow fan 14 for opening exhaust gear 1 is opening the proportioning valve 12 of exhaust gear 1 and is adjusting aperture for maximum, until through-flow
Blower 14 is according to steam discharge working time end of run.
For example, as shown in fig. 7, S10: whether detection cooking process terminates, if "Yes", carries out S11, if "No", after
Continuous culinary art, electromagnetic switch valve keeps opening state, and proportioning valve 12 inputs a constant current, is in proportioning valve 12 centainly
Aperture discharges steam；
S11: control water pump and electromagnetic switch valve are in close valve state, while it is in the open state to control cross flow fan 11；
S12: proportioning valve 12 inputs maximum current, keeps aperture maximum；
S13: cross flow fan 11 is according to long running when steam discharge (specific steam discharge duration is by program setting)；
S14: after 11 steam discharge of cross flow fan, shutdown.
The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model
Range.
