Background technology
At present, European type cooker hood integral installation highly determines that range hood is distant from the pot for producing oil smoke, negative pressure
Loss causes smoke absorption effect poor than larger, the easy both sides escape from exhaust fume collecting hood of oil smoke of pot top ascension.In order to improve
The range hood effect of range hood, people are improved the structure of range hood, and wherein common practice is to oil suction
The blower fan system of cigarette machine is improved, such as increases the power of blower fan, such as improve structure of impeller etc..Although this improve
The smoke absorption effect of range hood can be effectively lifted, it require that the structure of whole blower fan system is improved, it is not only complex,
But also negative pressuren zone when can not improve range hood work is distributed, negative pressure loses relative or larger, the oil smoke above the kitchen range top
Or easily escaped from the both sides of exhaust fume collecting hood.
Have by setting the structure of smoke deflector to prevent the range hood of fumes escaping, such as Application No. in the prior art
A kind of top-sucking kitchen ventilator with smoke deflector disclosed in 201410419676.4 Chinese patent, including body, exhaust fume collecting hood and
Smoke deflector, wherein exhaust fume collecting hood are connected with body, and blower fan is provided with body, and the exhaust fume collecting hood is provided with air inlet, the deflector
Just the air inlet of exhaust fume collecting hood is set, and there is spacing between deflector and exhaust fume collecting hood and form oil smoke passage.
Above-mentioned this range hood, makes negative pressuren zone by zero turn radius surrounding at smoke collecting chamber using monolithic smoke deflector, when
When carrying out cooking using single stove, now oil smoke amount is largely produced and quick ascension, attached wall of the oil smoke in smoke deflector in side
Under function influence, the suction inlet of lampblack absorber is entered from surrounding, because the distance that oil smoke undergoes from side to other side is long, is led
Cause energy loss big, and when oil smoke amount is excessive, escape phenomenon easily occurs for part soot gas.

Regulating loop 74 (being used to return to zero) and the second scale regulating loop 754 (being used to return to zero).First temperature sensor 61 and the first quarter
Degree regulating loop 74 is connected respectively to the input of the first amplifier 72, and the output end of the first amplifier 72 is connected to MCU71, the second temperature
The degree scale regulating loop 75 of sensor 62 and second is connected respectively to the input of the second amplifier 73, the output end of the second amplifier 73
It is connected to MCU71.In the present embodiment, the first scale regulating loop 74 and the second scale regulating loop 75 can be current potential
Device, is returned to zero using the reference as temperature sensor using preceding.
When range hood does not work, the first smoke deflector 41 and the second smoke deflector 42 are located in exhaust fume collecting hood 1, such as and exhaust fume collecting hood
1 bottom is flushed, so as to ensure the good appearance of range hood, referring to Fig. 2；When starting culinary art, range hood, first are opened
Temperature sensor 61 and second temperature sensor 62 sense the temperature of both sides, respectively T1 and T2 respectively, and will sense
Temperature value feeds back to MCU71, and MCU71 compares T1 and T2：
(1) T1 is worked as>T2 and | T1-T2 | during >=deta_T, deta_T be both sides using identical culinary art condition pass through
The maximum difference for the both sides temperature that temperature sensor monitors are obtained, MCU71 controls the first smoke deflector by the first drive mechanism 51
41 begin to decline, until decline a certain distance d1, d1 it is preferred can be according to the temperature gaps of both sides | T1-T2 | size determine
It is fixed；Correspondingly, in order to ensure the uniformity of the intake velocity entered before blower fan system (because the air quantity of the side of the first smoke deflector 41 adds
Greatly, thus speed increase), in order to ensure that the speed at the second smoke deflector 42 is equally increased, it is necessary to which MCU71 passes through the second driving machine
Structure 52 controls the second smoke deflector 42 to rise while the first smoke deflector 41 declines, until it is preferred to rise a certain distance L2, L2
Can be by d1 and the temperature gap of both sides | T1-T2 | determine, referring to Fig. 4；
(2) T1 is worked as<T2 and | T1-T2 | during >=deta_T, MCU71 pass through the second drive mechanism 52 control the second smoke deflector
42 begin to decline, until decline a certain distance d2, d2 it is preferred can be according to the temperature gaps of both sides | T1-T2 | size determine
It is fixed；Correspondingly, in order to ensure the uniformity of the intake velocity entered before blower fan system (because the air quantity of the side of the second smoke deflector 42 adds
Greatly, thus speed increase), in order to ensure that the speed at the second smoke deflector 42 is equally increased, it is necessary to which MCU71 passes through the first driving machine
Structure 51 controls the first smoke deflector 41 to rise while the second smoke deflector 42 declines, until it is L1 to rise a certain distance, L1 is excellent
That selects can be by d2 and the temperature gap of both sides | T1-T2 | determine, referring to Fig. 5；
(3) T1 is worked as>TH and | T1-T2 | during ＜ deta_T, the default higher limits of TH are such as more than conventional big oil smoke amount
In the case of the temperature that is obtained by temperature sensor monitors, MCU71 controlled by the first drive mechanism 51 and the second drive mechanism 52
Make the first smoke deflector 41 and the second smoke deflector 42 declines simultaneously, corresponding distance respectively d1 and d2, referring to Fig. 6；
(4) T1 is worked as<TH and | T1-T2 |<During deta_T, TH is default temperature upper limit, the first smoke deflector 41 and the
Two smoke deflectors 42 keep initial constant with the bottom flush position of exhaust fume collecting hood 1.
The utility model has the advantage of：(1) using double smoke deflector structures, negative pressuren zone can not only be extended out, also simultaneously
It can strengthen central negative pressure area, form the effect of multiaspect air intake；(2) by the monitoring of temperature sensor, anticipation kitchen is cooked
Prepare food situation, and then by automatically controlling, realize the lifting of adjustment both sides smoke deflector in real time, strengthen smoke absorption effect.
Embodiment two
Referring to Fig. 8 and Fig. 9, the difference with above-described embodiment one is, in the present embodiment, including the first driving machine
The drive mechanism of the drive mechanism 52 of structure 51 and second is used to drive the first smoke deflector 41 and the second smoke deflector 42 to rotate respectively.
First drive mechanism 51 includes the first motor 511 and first rotating shaft 512, and the first motor 511 is arranged on exhaust fume collecting hood 1
Rear side, one end of first rotating shaft 512 is connected with the output shaft of the first motor 511, and the other end is then rotatably arranged at exhaust fume collecting hood 1
Front side, the first smoke deflector 41 is connected with first rotating shaft 512, is fixed such as by the mode of welding.Correspondingly, the second drive mechanism
52 include the second motor 521 and the second rotating shaft 522, and the second motor 521 is arranged on the rear side of exhaust fume collecting hood 1, the one of the second rotating shaft 522
End is connected with the output shaft of the second motor 521, and the other end is then rotatably arranged at the front side of exhaust fume collecting hood 1, the second smoke deflector 42 and
Second rotating shaft 522 is connected, and is fixed such as by the mode of welding.To cause range hood overall appearance, first rotating shaft 512 and
