Description
Technical field
This utility model relates to a kind of lampblack absorber, particularly relates to a kind of lampblack absorber that can detect oil smoke concentration.
Background technology
It is dense to relevant environment index such as gas concentration, oil smoke that the Based Intelligent Control of existing lampblack absorber depends on sensor mostly
The accurate detection of degree, temperature, odorousness, Range switch etc..Wherein, it is achieved opening and closing automatically of lampblack absorber is mainly passed through
Detecting the sudden change that these indexs are grown out of nothing, the rotating speed or the gear that automatically control range hood fan are then main according to index value
Size.
Such as, the Chinese patent of Patent No. 20111003374.0, it is proposed that a kind of Smoke Detection system based on photographic head
System, it is possible to the size of detection amount of smoke, then automatically controls lampblack absorber work according to smokescope.In the program, need to arrange
Photographic head gathers the image of the lampblack absorber kitchen range top in kitchen, then also needs to arrange Smoke Detection unit and enters the image gathered
Row analyzing and processing, is then determined whether, if having oil smoke to produce, is then entered the concentration of smog by amount of smoke analytic unit
Row is analyzed, finally according to analysis result intelligent opening or closedown lampblack absorber.In the program, need to arrange the Smoke Detection list of complexity
Unit and amount of smoke analytic unit, and camera collection is the image of the lampblack absorber kitchen range top in kitchen, and the lampblack absorber kitchen range top is most
Being non-smooth, and during cooking, food materials can constantly stir, therefore the background after shooting is more complicated, is unfavorable for follow-up
The analysis of Smoke Detection unit and follow-up amount of smoke analytic unit judges, relatively costly, it is judged that inaccurate.
Further for example, the Chinese patent of Patent No. 201410519856.X, propose by the pan being arranged on gas-cooker
The temperature sensor in the bottom of a pan, detect cooking bottom temperature in real time, gas-cooker main control unit can be examined according to cooking bottom temperature testing circuit
The cooking bottom temperature measured calculates oil smoke amount, and then oil smoke amount information is passed through wireless signal transmitting module by gas-cooker main control unit
It is sent to reception of wireless signals module, reception of wireless signals module and then oil smoke amount information is sent to lampblack absorber main control list
Unit, lampblack absorber main control unit controls fan according to oil smoke amount information.
Further for example, the Chinese patent of patent No. 201280006420.X provides a kind of gratin according to heating device
Temperature changes the smoke exhaust ventilator of the air quantity of pressure fan, by arranging infrared temperature sensor detection gratin temperature and the cooking
The mean temperature of thing environment temperature and the environment temperature of detection heating device, come certainly according to gratin temperature and cooking device signal
Determine the air quantity of pressure fan.
Further for example, the patent of Application No. 201110061478.1 proposes about a kind of cigarette stove coordinated control system and control thereof
Molding group, lampblack absorber have wind-force regulation unit, control module include temperature-sensitive sticker, control unit, signal transmitter unit with
Signal receiving unit, temperature-sensitive sticker is corresponding with kitchen range, control unit respectively with temperature-sensitive sticker and signal transmitter unit phase
Even, the temperature signal that control unit receives and processes from temperature-sensitive sticker regulates signal, wind-force regulation signal to obtain wind-force
It is transferred to signal transmitter unit.
The deficiency of above method is to detect kitchen range, the sensor of pan state separates with lampblack absorber, need to be by letter
Breath transmission could control switch for cooker hood, and this will bring the matching problem of the increase of cost and kitchen range pan and lampblack absorber；Separately
On the one hand, for controlling the index that the index of lampblack absorber air quantity is often indirect, such as food materials temperature, pan temperature, kitchen range temperature
The indexs such as degree and exhaustion drain the strong correlation relation that do not exists between oil smoke Air Quantity Required, and controlling judgement may be inaccurate.
To this end, the Chinese patent of Patent No. ZL201420325713.0, disclose one can directly gather oil smoke concentration,
Then carry out the Intelligent drainage cigarette lampblack absorber of wind speed regulation according to oil smoke concentration, it includes body, blower fan and master controller, main control
Device controls blower fan operating, and this lampblack absorber also includes: infrared spectrum sensor-based system, and infrared spectrum sensor-based system includes infrared light emission
Portion, infrared light acceptance division, optical sensor system and spectroscopic analysis system, the infrared light that described infrared light emission portion launches is to body
Behind the oil smoke region of lower section, reflecting through oil smoke or by oil smoke, infrared light acceptance division receives this transmission or reflection light and passes through light
Learn sensor-based system transmission and calculate smokescope number to spectroscopic analysis system, the spectrum of the infrared light that this system is received by analysis
According to, and these data are transmitted to master controller；Master controller includes speed calculation unit, and this computing unit passes through spectrum analysis system
The smokescope data judging blower fan gear that statistics is calculated, and according to blower fan gear output drive signal；Drive circuit, with main control
Device connects, and drives blower fan by corresponding rotation speed operation by receiving the driving signal of speed calculation unit.
In said structure, infrared spectrum sensor-based system detection oil smoke concentration is used just can directly to gather oil smoke concentration, oil smoke
The control of machine becomes the most simple and convenient.But the change of oil smoke concentration to be monitored accurately by oil smoke sensor, installation site is selected
The reasonability taken is very important, the most important condition be sensor detection range will oil smoke run must be on path, so
And in prior art, oil smoke sensor to be often arranged on exhaust fume collecting hood, when oil smoke amount is less, tend not to detect,
Therefore the detection sensitivity causing oil smoke sensor is the highest.
