Description
Technical field
The present invention relates to a kind of baking box and method of work thereof.
Background technology
Along with the development of foreign trade, people increasingly like Western-style cooking method.Self-control DIY cake, baking meat
Fallen over each other to pursue by people Deng diet style.Therefore, baking box also receives highest attention as new cooking tools.
Baking box is as airtight a, utensil for baking food, and its internal capacity is relatively big, and general employing temperature sensor is surveyed
Measure its internal temperature；And baking box internal temperature sensor is little due to its volume, the reasons such as mounting means is limited, cause it
The temperature of certain point around interior oven walls can be measured, the temperature put using this measurement as integrated oven internal temperature maybe by this temperature
Degree is considered as the temperature of cooked food, then carries out subsequent heat control according to this temperature, the fine degree band that can cook
Carry out bigger deviation.Some baking box, in order to strengthen cooking chamber inner air convection heat transfer effect, have employed rotary fan to increase
The disturbance of strong air.Due to the single direction rotation of general fan, easily cause same layer left and right sides heat exchange situation different, i.e. left and right
Both sides non-uniform temperature.For above-mentioned reasons, use single temp probe as the temperature foundation of whole baking box, not section
Learn, easily cause food that the uneven consistent situation of color and luster occurs in baking.

In cooking chamber bottom, be used for gathering cooking chamber temperature of lower the second temperature sensor.
Preferably, described first temperature sensor is arranged on cooking chamber upper side wall, and described second temperature sensor is arranged on
In cooking chamber lower wall.
As improvement, described baking box control unit includes food upper and lower surface temperature conversion module, this food upper and lower surface
Temperature conversion module calculates by the temperature of baking food upper and lower surface in the following way:
By baking food upper surface temperature=C1ti+C2t1, wherein C1=λ/(λ+h)；C2=h/ (λ+h)；tiFor quilt
Baking food internal temperature；t1It it is the temperature that records of the first temperature sensor；λ is the thermal conductivity factor of food, and λ is less than 1
W/(㎡*K)；H is convection transfer rate, h=3～10W/ (* K)；
By baking food underlaying surface temperature=C1ti+C2t2, wherein C1=λ/(λ+h)；C2=h/ (λ+h)；tiFor quilt
Baking food internal temperature；t2It it is the temperature that records of the second temperature sensor；λ is the thermal conductivity factor of food, and λ is less than 1
W/(㎡*K)；H is convection transfer rate, h=3～10W/ (* K).
Improving, preserve the baking flow process of different food in described baking box control unit, this baking flow process includes: food
Thing upper surface needs the time toasted and food lower surface to need the time of baking at a certain temperature at a certain temperature.
The present invention solves the technical scheme that above-mentioned further technical problem used: a kind of work with said structure baking box
Make method, it is characterised in that: baking box control unit Real-time Collection the first temperature sensor and the temperature of the second temperature sensor,
Then calculate by the temperature of baking food upper and lower surface by food upper and lower surface temperature conversion module, when being baked
When food upper surface temperature processed is more than first threshold with upper surface demand temperature gap, regulation adds the caloric value of heat pipe, directly
It is more than or equal to 1 with upper surface demand temperature gap less than or equal to first threshold to by baking food upper surface temperature, then sentences
Break by baking food underlaying surface temperature and lower surface demand temperature gap, when being needed with lower surface by baking food underlaying surface temperature
When asking temperature gap to be more than Second Threshold, adjustment adds the caloric value of heat pipe, when by baking food underlaying surface temperature and following table
Face demand temperature gap hour, equal to time during Second Threshold more than or equal to 1, adds the caloric value of heat pipe under adjustment；When by baking
Food upper surface temperature and upper surface demand temperature gap are less than 1, by baking food underlaying surface temperature and lower surface demand temperature
Degree difference is less than 1, according to the baking of this group food pre-saved in the type of baking food and baking box control unit
Flow process carries out baking.
Compared with prior art, it is an advantage of the current invention that: the present invention arrange two can gather respectively cooking chamber top and under
The temperature sensor of portion's temperature, it is thus possible to control the demand of oven cooking cycle difference food more accurately, makes food upper and lower surface
Temperature more meets the temperature that it is required.
