It prepares food intracavitary temperature, due to adjusting the temperature of cooking cavity by the temperature controlled fan revolving speed detected, in such cooking cavity
Temperature change more mitigate, fluctuating range is small, and by hot-air flowing heating make cook cavity temperature it is more uniform.
Specifically, in the present embodiment, according to above-mentioned control method, the control method of electric oven starting heating are as follows:
The memory cell of the master control borad 5 of electric oven contains the mapping table of preset temperature T and rotation speed of the fan A, leads to
It crosses operation panel and selects corresponding gear n, the corresponding target temperature of gear n is Tn, start the electric oven, heating element heats,
Control unit detects the cooking temp in cooking cavity, the cooking temp S and the preset temperature T by temperature sensor
Relationship；
When the cooking temp S detected is less than the target temperature Tn, rotation speed of the fan A is controlled to be less than target temperature Tn
Correspondence revolving speed An operation.This stage control is according to temperature change section in the cooking cavity detected, control unit control
Rotation speed of the fan changes accordingly, runs fan using the slow-speed of revolution when temperature is low, and the heat reduced in cooking cavity is unnecessary
Scatter and disappear, to culinary art cavity space more rapidly heat up, be also beneficial to the intracavitary temperature everywhere of rapidly cooking uniformity.
The present embodiment, the specific steps of the electric oven temperature rise period control method are as follows:
The memory cell of the master control borad 5 of electric oven contains the mapping table of preset temperature T and rotation speed of the fan A: rising
Thermophase: T0 < T1 < T2 < T3, A1 < A2 < A3, A1 correspond to preset temperature section: T0≤T < T1；A2 corresponds to preset temperature
Section: T1≤T < T2；A3 corresponds to preset temperature section: T2≤T < T3.
Target temperature needed for selecting food by the operation panel of electric oven cooks gear accordingly, starts electric oven, main
It controls plate 5 and controls helical heating pipe heating, and control motor with the corresponding minimum speed A1 operation of initial temperature T0, motor drives wind
42 rotation of fan, fan 42 guide the heat that snail heating tube 41 generates into the cooking cavity 31 along air duct；
Master control borad 5 detects the cooking temp in cooking cavity by temperature sensor and then compares the culinary art detected
The size relation of temperature S and the preset temperature T；
When the cooking temp S is less than the first preset temperature T1, master control borad 5, which controls fan, to be continued with revolving speed A1 fortune
Row；When the cooking temp S rises to the first preset temperature T1 and is less than the second preset temperature T2, master control borad 5 is controlled
Fan is with revolving speed A2 operation；When cooking temp S reaches third preset temperature T2, master control borad 5 controls fan with revolving speed An fortune
Row, until reaching target temperature Tn；
After cooking temp S reaches target temperature Tn, the temperature rise period terminates, in order to keep food cooking temperature relative constant,
The food of culinary art is more palatable, and after the temperature rise period, Household electric oven enters the constant temperature stage of culinary art.
In the present embodiment, fan is driven by motor, and rotation speed of the fan A is identical as the motor speed, and the motor highest turns
Speed is 3000rpm, is divided into 3 gears, and gear revolving speed is respectively as follows: A1=1000 revs/min, A2=2000 revs/min, A3
=3000 revs/min；Corresponding preset temperature point is respectively as follows: T0=0 DEG C, and T1=120 DEG C, T2=160 DEG C, T3=
200℃。
It is appreciated that the preset temperature T can be selected according to actual needs, such as 0 DEG C, 30 DEG C, 60 DEG C, 80
℃,100℃,120℃,140℃,160℃,180℃,190℃,200℃.When preset temperature is too low, food mouthfeel is relatively
Difference may scald user when preset temperature is excessively high.
It is appreciated that the revolving speed A of fan can be adjusted according to the actual situation, for example, 500 revs/min, 1000 revs/min,
1500 revs/min, 2000 revs/min, 2500 revs/min, 3000 revs/min.If the revolving speed of fan is too low, wind-force compared with
It is weak, heat cannot be blowed into downwards cooking cavity completely, if the revolving speed of fan is excessively high, the noise of fan is excessive, influences surrounding
Environment.
In the present embodiment, the motor is the speed regulating motor with multi gear revolving speed, general gear motor, simplified control circuit
Setting.
It is appreciated that the motor is also possible to ordinary motor, then motor is adjusted the speed by silicon-controlled.
Embodiment two.
The difference between this embodiment and the first embodiment lies in: the control method further includes adjusting cooking temp to tend towards stability
Different, the other structures of the present embodiment electric oven and the controlling party of temperature rise period is arranged in the control method and air outlet in constant temperature stage
Method is identical as the electric oven setting of embodiment one.
As shown in figure 3, Household electric oven after the temperature rise period, enters the constant temperature stage of culinary art, the constant temperature stage
Control method are as follows:
The memory cell of the master control borad 5 of electric oven contains the parameter preset in constant temperature stage: with the preset temperature T-phase
The upper lower limit value that corresponding temperature is adjusted: Wn-1 and Wn+1, and Wn-1 < Tn < Wn+1.
When master control borad 5 detects that the cooking temp S is greater than temperature adjustment value Wn+1 by temperature sensor, master control borad 5
The fan is controlled with revolving speed An operation, the heating tube stops heating；The cooking temp S is reduced to temperature adjustment value Wn-1
When, master control borad 5 controls the fan with revolving speed An-1 operation, the heating tube heating.As a working cycles, constantly follow
Ring, the cooking temp that master control borad 5 controls in the cooking cavity are stable at preset temperature range.
Certainly, when the constant temperature stage, when control unit detects that the cooking temp S is greater than temperature tune by temperature sensor
When section value Wn+1, the heating tube can also continue to heat, and adjust temperature by fan rotation, and opposite heating tube stops work
Make, the temperature decline curve of the method is gentler, but fall time can extend.
It is appreciated that the fluctuating range size in constant temperature stage can be controlled according to the actual situation, i.e., to the default temperature
Limit value Wn-1 and the Wn+1 difference range that the corresponding temperature of degree T-phase is adjusted is controlled, and the difference of Wn+1 and Wn-1 may is that 5
℃、10℃、15℃、20℃。
More preferably setting be, the air outlet that the cooking cavity of the electric oven is in communication with the outside it is adjustable.In this implementation
In example, air outlet is equipped with mobilizable blade, similar to the form of shutter, in the temperature rise period, the moving vane of air outlet
It closes, to make heat in culinary art cavity circulation, avoids scattering and disappearing for heat；At the constant temperature stage, the moving vane of air outlet
Air outlet size can be adjusted with constant temperature target temperature difference, more air-flow can be flowed out by air outlet, and guarantee is cooked enough
Fuel value of food prepare food simultaneously, reduces impact of the thermal current to electric oven device.
It is appreciated that when the temperature rise period, air outlet be also it is openable, it is described compared to the constant temperature stage
The area of the opening of temperature rise period air outlet is less than the area of the constant temperature stage air outlet.
It is appreciated that the air outlet of the application adjusts the form for being also not limited to similar shutter, other traditional regulation sides
Formula all should belong to the protection scope of the application.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
