When Control Component 16 output pressure steams mode of operation, Control Component 16 exports control signal makes steam valve 11 and electromagnetic lock 2 all close, now chamber door can not be opened, user is avoided to be scalded by steam, first Control Component 16 exports the heating element heats that control signal makes steam generator 8, thus generation steam is input in cooking chamber 13, steam is made to be agglomerated into supersaturated vapor in cooking chamber 13, the Temperature numerical of Control Component 16 Real-time Collection temperature sensor 9 and the pressure value of pressure sensor simultaneously, when the temperature in cooking chamber reaches the first Temperature numerical that Control Component presets or when the pressure in cooking chamber reaches the first pressure value that Control Component presets, Control Component 16 exports control signal to be stopped heating to the heating element heater of steam generator 8 thus stops producing steam, when the temperature in cooking chamber 13 reach Control Component preset second temperature numerical value or when the pressure in cooking chamber reach Control Component preset the second pressure value time, Control Component 16 exports control signal makes steam generator continue heat make-up steam to the heating element heater of steam generator 8, so move in circles heat food, here, the first Temperature numerical is generally set to some temperature values in 95 ~ 105 degrees Celsius, and best value is 100 degrees Celsius, second Temperature numerical is traditionally arranged to be 120 ~ 130 degrees Celsius, and best value is 125 degrees Celsius, first pressure value generally establishes atmospheric pressure value, second pressure value is traditionally arranged to be 1.2 ~ 1.5 atmospheric pressure value,
Under Control Component output pressure steams mode of operation situation:
When temperature sensor 9 is malfunctioning, culinary art room pressure is detected by pressure sensor 12, when cooking room pressure when rising to the warning force value that Control Component is preset, Control Component exports control signal and makes steam generator stop heating to steam generator thus stop producing steam, Control Component output control signal makes steam valve open to steam valve simultaneously, until culinary art room pressure is reduced to the safe pressure value that Control Component is preset, Control Component exports control signal makes steam valve close to steam valve; Meanwhile, when the pressure in cooking chamber reach Control Component preset the second pressure value time, Control Component exports control signal makes steam generator continue heat make-up steam to steam generator, and so move in circles heat food; Here, guard against force value and be generally 1.6 ~ 1.7 atmospheric pressure value; And safe pressure value is generally 1 ~ 1.2 atmospheric pressure value, the second pressure value is traditionally arranged to be 1.2 ~ 1.5 atmospheric pressure value.
When pressure sensor 12 is malfunctioning, culinary art indoor temperature is detected by temperature sensor, when cooking room pressure when rising to the warning temperature value that Control Component is preset, Control Component exports control signal and makes steam generator stop heating to steam generator thus stop producing steam, Control Component output control signal makes steam valve open to steam valve simultaneously, until culinary art Indoor Temperature is reduced to the safe temperature value that Control Component is preset; Here, warning temperature value is generally set to 130 degree, and safe temperature value is generally less than 125 degree.
When normal pressure steams mode of operation that what no matter Control Component 16 exported is or pressure steam mode of operation, after the cooking process of setting completes, Control Component outputs signal to the 3rd Unidirectional solenoid valve 18 makes the 3rd Unidirectional solenoid valve open, water is remained because of potential energy difference inflow water level control box 4 in steam generator, simultaneously, Control Component outputs signal to the second water pump 19 makes the second water pump open, water in water level control box is extracted in water tank, the more convenient user of water tank cleans, this mode, steam generator and water level control box can be protected, under not service condition, all the time anhydrous, available protecting not easily removes the service life of steam generator and the water level control box cleaned.
In addition, under pressure steams mode of operation, after completing to make culinary art, cooking chamber quick pressure releasing, make user can take out food very soon, be also provided with quickly cooling device in described cooking chamber, described quickly cooling device comprises the sprinkler head 10 be arranged in cooking chamber, this sprinkler head is communicated with described water tank 1 or water level control box 4 by the second Unidirectional solenoid valve 7, and described second Unidirectional solenoid valve 7 is connected with described Control Component.When Control Component output pressure steams mode of operation, after the cooking process of setting completes, Control Component exports control signal makes the second Unidirectional solenoid valve open to the second Unidirectional solenoid valve 7, sprinkler head ejection normal-temperature water makes supersaturated vapor in cooking chamber cool fast in saturated vapor, when pressure sensor detect culinary art room pressure be less than Control Component preset the 3rd force value time, Control Component exports control signal makes steam valve open, the excess steam in cooking chamber is made to discharge cooking chamber, then Control Component output control signal makes electromagnetic lock open to electromagnetic lock, chamber door can open taking-up food.
The double-purpose steam box that the present embodiment provides, collection atmospheric steam, steam dual-heated pattern, existing common normal pressure steamer culinary art advantage: retain food color, nutritional labeling to greatest extent, have again pressure steam box distinguishing feature simultaneously:
1, cooking temp improves, firing rate is very fast: because supersaturated vapor exists certain pressure, corresponding higher (1.2 ~ 1.5 atmospheric pressure of corresponding cooking temp, corresponding temperature 105 ~ 110 degree), heat trnasfer is faster, and firing rate 1.2 atmospheric pressure can improve speed 20%;
2, penetration depth is dark, and mouthfeel is glutinous: supersaturated vapor temperature is higher, and heat penetration depth is comparatively dark, so be conducive to the precipitation of grease in animal food, and crude fibre modification, steam the difficult prepared food material such as joint, soft-shelled turtle, meat relaxes soft, and mouthfeel is glutinous;
3, airtight good: pressure steam box is similar to vacuum state substantially, favourable to preservation polyphenoils; Pressure steam box heat leak is few, and steam utilization is higher, so the electricity consumption that more conserves water.
Both mode of operations organically combines, and cooking food not only delicious food but also quick, greatly can facilitate, enrich people's dietetic life.
