Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figures 1 to 6, the basic environment of the air guide structure application of the electric oven in the present embodiment are as follows: oven inner container
Rear portion be provided with hot wind machine baffle 1, be provided between hot wind machine baffle 1 and the rear inner wall of oven inner container back heating tube 200, back
The basic setting annular in shape of heating tube 200, air-heater 100 are then arranged in the center cavity of back heating tube.Air-heater 100 works,
Then back heating tube 200 is blown out from the air outlet 11 being arranged on hot wind machine baffle 1.If the structure of electric oven such as background technique
Middle Authorization Notice No. is structure disclosed in the utility model patent of CN206026110U, then the air guide structure in the present embodiment can be with
It applies at the air outlet 11 of each hot wind machine baffle.
The air guide structure of electric oven in the present embodiment includes hot wind machine baffle 1, blade 3, driving mechanism, controller 4, wind
Pressure sensor 5.Wherein the surrounding of hot wind machine baffle 1 is tightly attached on oven inner container shell inner wall, on the left and right side of hot wind machine baffle 1
Offer the air outlet 11 of strip, the side of each air outlet 11 is provided with a blade 3, the shape of blade 3 with go out
The shape in air port 11 matches, which is rotatably connected on the back of hot wind machine baffle 1 by a shaft 6, with blade 3
Rotation can open, close air outlet 11.
Wind pressure sensor 5 is arranged at air outlet 11, and for the hot-blast pressure signal at detection air port 11, which is passed
Sensor 5 is electrically connected with controller 4, and the hot-blast pressure signal that wind pressure sensor 5 detects sends controller 4,4 basis of controller to
The outlet air pressure data of hot-blast pressure signal calculating air outlet 11.When the food volume to be roasted placed in oven is larger, or
When the shape of food to be roasted is unfavorable for the hot wind flow of the blowout of air outlet 11, then the wind pressure at air outlet 11 can then become larger, this
When need the opening aperture of blade 3 to increase to increase the air-out area of air outlet 11, so that hot wind is in the liner of oven
Smoothly circulation avoids occurring the baking effect that hot wind is vortexed and influences food at air outlet 11.On the contrary, then reducing blade 3
Open aperture.
Controller 4 in the present embodiment can be separately provided, and the master controller in oven also can be directly used.Driving machine
Structure includes that motor 7 and the transmission component with the transmission connection of motor 7, motor 7 are electrically connected with controller 4.Transmission component includes connecting
The second gear 9 for connecing the first gear 8 on 7 output shaft of motor, being meshed with first gear 8, second gear 9 are fixedly connected on
In shaft 6, the both ends of shaft 6 are fixed on hot wind machine baffle 1.
The wind-guiding method realized in the present embodiment using aforementioned air guide structure, is included the following steps:
The rotation of blade 3 aperture is set N number of aperture gear by step 1, defines the angle that each aperture gear blade 3 is opened,
Input the corresponding wind pressure threshold value [P of each aperture gear1,P2,……,Pi,……,PN], wherein i, N are natural number, 1≤i≤N；
Step 2, when oven choose mode need to carry on the back heating tube worked when, controller 4 detects air-heater 100
After starting working signal, the first rotating opening air outlet 11 of blade 3；If the operating mode for the first time in use, blade 3 first according to
The corresponding open angle rotating opening of 1st grade of aperture gear, if the operating mode non-first time uses, blade 3 is according to roasting
Once with the corresponding open angle rotating opening of the aperture gear recorded when identical mode of operation before case；
Wind pressure signal at step 3,5 detection air port 11 of wind pressure sensor simultaneously sends controller 4 to, 4 basis of controller
Wind pressure signal, which calculates, obtains wind pressure data P；
Step 4, by wind pressure data P, successively wind pressure threshold value corresponding with aperture gears at different levels is compared, if Pn≤ P <
Pn+1, then controller 4 controls driving mechanism driving blade 3 and turns to the corresponding open angle of n-th grade of aperture gear；
Step 5, circulation carry out step 3 and step 4, until after controlling the silence signal for detecting air-heater 100, control
Device 4 processed controls driving mechanism driving blade 3 and rotates and close air outlet 11, while controller 4 records oven this time operating mode
The aperture gear of lower blade 3；Furthermore hot gas is spread for convenience, and controller 4 is in the signal for detecting that air-heater 100 stops working
Afterwards, the rotation closing air outlet 11 of driving mechanism driving blade 3 is controlled after can waiting for a period of time.
