Description

A kind of baking box

Technical field

This utility model is related to a kind of baking box.

Background technology

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 airtight as one, the utensil of baking food, and its internal capacity is larger, and typically adopts temperature sensor to survey Measure its internal temperature；And baking box internal temperature sensor is due to its small volume, the reason such as mounting means is limited, cause it can only survey Around amount interior oven walls, the temperature of certain point, is considered as using the temperature of this measurement point as integrated oven internal temperature or by this temperature The temperature of cooked food, then carries out subsequent heat control according to this temperature, and the fine degree that can cook is brought larger Deviation.Some baking boxs, in order to strengthen culinary art indoor air convection heat transfer effect, employ rotary fan to strengthen disturbing of air Dynamic.Due to the single direction rotation of general fan, easily cause same layer left and right sides heat exchange situation difference, that is, left and right sides temperature is uneven Even.For above-mentioned reasons, using single temperature probe as whole baking box temperature foundation, not science, easily lead to food The uneven consistent situation of color and luster occurs in baking.

Utility model content

Technical problem to be solved in the utility model is to provide one kind can be precisely controlled food for above-mentioned prior art The baking box of heating-up temperature.

This utility model solves the technical scheme that adopted of above-mentioned technical problem：A kind of baking box, including casing, is arranged on Cooking chamber in casing, is arranged on the upper heating tube being located in casing above cooking chamber, is arranged in casing and is located under cooking chamber Side lower heating tube, for measuring the temperature-detecting device of cooking chamber internal temperature, with temperature-detecting device, upper heating tube and under Heating tube connect for control upper heating tube and lower heating tube work baking box control unit it is characterised in that：Described temperature Detection means comprises positioned at cooking chamber top for gathering the first temperature sensor of cooking chamber upper temp, and is located at culinary art Room bottom, be used for gathering cooking chamber temperature of lower second temperature sensor.

Preferably, described first temperature sensor is arranged on cooking chamber upper side wall, and described second temperature sensor is installed In cooking chamber lower wall.

Compared with prior art, the utility model has the advantage of：This utility model arranges two and can gather culinary art respectively The temperature sensor of room upper and lower temperature, so as to more accurately control the demand of oven cooking cycle difference food, makes food Upper and lower surface temperature more meets its required temperature.

Brief description

Fig. 1 is the structural representation of baking box in this utility model embodiment.

Fig. 2 is the job control logic chart one to heating tube for the baking box in this utility model embodiment.

Fig. 3 is the job control logic chart two to heating tube for the baking box in this utility model embodiment.

Specific embodiment

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

Baking box as shown in Figure 1, including casing 7, is arranged on the cooking chamber 8 in casing 7, is arranged on to be located in casing 1 and cooks The upper heating tube 3 prepared food above room, is arranged on the lower heating tube 4 being located in casing below cooking chamber, for measuring inside cooking chamber The temperature-detecting device of temperature, be connected with temperature-detecting device, upper heating tube and lower heating tube for control upper heating tube and The baking box control unit (not shown) of lower heating tube work, described temperature-detecting device comprises positioned at cooking chamber upper side wall For gathering the first temperature sensor 1 of cooking chamber upper temp, and be located at cooking chamber lower wall, be used for gathering under cooking chamber Portion's temperature second temperature sensor 2.

Described baking box control unit includes food upper and lower surface temperature conversion module, this food upper and lower surface temperature conversion Module calculates in the following way by the temperature of baking food upper and lower surface：

By baking food upper surface temperature=C₁t_i+C₂t₁, wherein C₁=λ/(λ+h)；C₂=h/ (λ+h)；t_iIt is by baking Food therein temperature；t₁The temperature recording for the first temperature sensor；λ is the heat conductivity of food, and λ is less than 1W/ (* K)；h For convection transfer rate, h=3～10W/ (* K)；

By baking food underlaying surface temperature=C₁t_i+C₂t₂, wherein C₁=λ/(λ+h)；C₂=h/ (λ+h)；t_iIt is by baking Food therein temperature；t₂The temperature recording for second temperature sensor；λ is the heat conductivity of food, and λ is less than 1W/ (* K)；h For convection transfer rate, h=3～10W/ (* K).

The baking flow process of different foods is preserved, this baking flow process includes in described baking box control unit：Food upper table Face needs the time toasted and food lower surface to need the time of baking at a certain temperature at a certain temperature.

Baking box control unit Real-time Collection the first temperature sensor and the temperature of second temperature sensor, then pass through food Upper and lower surface temperature conversion module calculates by the actual temperature of baking food upper and lower surface, when by baking food upper table When face demand temperature is more than first threshold t1 with upper surface actual temperature difference DELTA 1, the caloric value of heating tube in regulation, until quilt Baking food upper surface temperature and upper surface demand temperature gap Δ 1 are less than or equal to first threshold t1 and are more than or equal to 1, then judge By baking food lower surface demand temperature and lower surface actual temperature difference, when by baking food underlaying surface temperature and lower surface need Ask temperature gap Δ 2 be more than Second Threshold t2 when, the caloric value of heating tube in adjustment, when by baking food underlaying surface temperature and under When surface demand temperature gap Δ 2 is less than or equal to be more than or equal to 1 when Second Threshold t2 is big, the caloric value of the lower heating tube of adjustment；Quilt Baking food upper surface demand temperature and upper surface actual temperature difference DELTA 1 are less than 1, when by baking food underlaying surface temperature with Surface demand temperature gap Δ 2 is less than 1, and baking box control unit is according to pre- in the type of baking food and baking box control unit The baking flow process of this group food first preserving carries out baking, simultaneously baking box control unit continue monitoring by baking food upper surface and The actual temperature of lower surface；Referring to shown in Fig. 2,3.
