Roast food area, δ are blackbody coefficient (5.67 × 10-8), and T1 is electric heating pipe surface absolute temperature, and T2 is to roast food table
Face absolute temperature.
Referring to Fig.2, implementing the electric oven provided for the utility model, when the same section in arc electrothermal tube has 4
When hot spot, it is respectively defined as hot spot 1, hot spot 2, hot spot 3 and hot spot 4, wherein hot spot 1 and hot spot 4 are the same as high
H1, hot spot 2 and hot spot 3 are the same as high H2, and H2> H1.To roasting point A with wait bake point B be heated in cooking process a little 1,
The radiant heat transfer of hot spot 2, hot spot 3 and hot spot 4.
Wherein, the outside radiation amount of amount of radiation/electrothermal tube of ε=to roast food by electrothermal tube, takes raying face length
It can be obtained according to ascent formula and its additive property wait bake radiation angle of the point A by the hot spot 2 of electrothermal tube for unit length 1
For coefficient:
ε2, A={ arctan (L1/H2)-arctan[(L1-1)/H2]}/2π；
Then to the radiation heat transfer total amount of roast food being subject to wait bake point A are as follows:
QA arc=Q1,A+Q2,A+Q3,A+Q4,A
Then to the radiation heat transfer total amount of roast food being subject to wait bake point B are as follows:
QB arc=Q1,B+Q2,B+Q3,B+Q4,B
It is then J wait bake point A with the uniformity wait bake the radiation heat transfer that point B is subject toArc=QA arc/QB arc。
Refering to Fig. 3, in the prior art, to roasting point A and wait bake hot spot of the point B in baking process by plane electrothermal tube
1, the radiant heat transfer of hot spot 2, hot spot 3 and hot spot 4.QA is flat、QBFlat and JIt is flatRespectively indicate to roasting point A with wait bake point B by
The radiation heat transfer total amount and uniformity of plane electrothermal tube.
It is calculated by bringing radiation heat transfer formula into it is found that JIt is flat< JArc< 1, so using provided by the embodiment of the utility model
When the electrical heating elements 30 of arc-shaped, it is ensured that electrical heating elements 30 be transmitted to it is more uniform to the radiant heat of roast food everywhere,
To guarantee the being heated evenly property to roast food, the ripe degree of food or upper coloration are improved, guarantees baking effect.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
