A kind of lampblack absorber and monitoring method for monitoring kitchen odorTechnical field
The present invention relates to lampblack absorber, mainly a kind of lampblack absorber and monitoring method for monitoring kitchen odor.
Background technology
With the lifting of living condition, the food of people has been various, will there are various gas in such kitchenTaste, such as：From drinks, from flavouring, from meat, from vegetable and fruit class etc..The generation and mixing of various smellsCan cause there is unpleasant " strange taste " in kitchen environment, so as to influence the mood of people and healthy.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of lampblack absorber for monitoring kitchen odorAnd monitoring method, air in kitchen taste can be in real time monitored, once there is strange smell in kitchen, then lampblack absorber can be automaticOpen, change air in kitchen, be finally reached the purpose of removal kitchen strange taste so that air in kitchen remains clean.
The purpose of the present invention is completed by following technical solution.The lampblack absorber of this monitoring kitchen odor, includingWhole machine, data processing and control system and smell monitoring sensor, the smell monitoring sensor are arranged on the exhaust fume collecting hood of whole machineInner surface, air in kitchen smell is detected by gas diffusion mode.
The monitoring method of the lampblack absorber of monitoring kitchen odor of the present invention, step is as follows：Smell is monitored into sensorInstalled in the exhaust fume collecting hood inner surface of whole machine, air in kitchen smell, smell sensor detection kitchen are detected by gas diffusion modeAir odor, and detection data is transferred to data processing and control system in real time, data by after analyzing and processing, dataTreatment will carry out real-time control with control system to whole machine, and its control mode is controlled for the size of exhaust air rate.
The smell monitoring sensor needs to use specific control method, and its step is as follows：
1) smell monitoring function is manually opened；
2) smell monitoring sensor initializing, preheating time T, while obtaining air odor grade threshold values；
3) judge whether present air has peculiar smell, if air free from extraneous odour, continues to run with this step, if air exist it is differentTaste, then into 4)；
4) range hood fan is opened, according to present air peculiar smell grade, regulating air volume；
5) judge whether peculiar smell is drained, is returned 3) if drained, if air also has peculiar smell, keep the step notBecome.
The air odor grade threshold values acquisition modes of the smell monitoring sensor are as follows：
1) electricity is gone up first, and the time starts timing, do not processed during preheating；
2) after the completion of preheating, the magnitude of voltage of feedback signal, the secondary data of record per second, continuous record 30 times, and handle are obtained30 this data carry out average value treatment, finally give a reference value V0；
3) per 30 secondary datas every other hour, are recorded again, data logging interval is still 1 second, and this data is put down 30Average value processing, finally gives a reference value V1, and V1 and V0 are compared, and judges that smaller value therein is defined as V0, and this V0 is newA reference value；
4) it is every just to carry out a step 3 every other hour in the case where not powering off).
At 5~10 minutes, there is ripple in its scope to the span of initialization preheating time T of the smell monitoring sensorDynamic property according to actual working environment and sensor performance, it is necessary to do appropriate correcting process.
Sensor of the smell monitoring sensor from semiconductor type redox reaction.
According to present air peculiar smell grade, the mode of regulating air volume is as follows：
1) a reference value V0 is obtained；
2) current data V-V0=△ V, by the size for judging the numerical value of △ V to control cigarette fan delivery；
3) 0 volt of ＜ △ V≤0.5 volt, cigarette machine does not run；
0.5 volt of ＜ △ V≤1 volt, cigarette machine opens 1 grade of air quantity；
1 volt of ＜ △ V≤1.5 volt, cigarette machine opens 2 grades of air quantity；
1.5 volts of ＜ △ V≤2 volt, cigarette machine opens 3 grades of air quantity；
2 volts of ＜ △ V, cigarette machine opens quick-fried air quantity；
4) step 3) scope there is fluctuation, it is necessary to do appropriate Corrections Division according to actual lampblack absorber overall performanceReason.
Beneficial effects of the present invention are：Whole machine can in real time monitor the air odor in kitchen, once there is peculiar smell in kitchen,Ventilatory is then opened, the cleaning of air in kitchen is kept.

Specific embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：
The lampblack absorber of this monitoring kitchen odor of the present invention, it solves the technical scheme bag that technical problem is usedInclude：(1) whole machine, data processing and control system, (3) smell monitoring sensor.Smell sensor is internally embedded in whole machine (1)(3), smell is monitored sensor (3) and needs to be arranged on the exhaust fume collecting hood inner surface of whole machine (1), and kitchen is detected by gas diffusion modeAir odor.The smell monitors sensor (3) typically from the sensor of semiconductor type redox reaction, smell sensor(3) detect the air odor in kitchen, and detection data is transferred to data processing and control system in real time, data are by analysisAfter treatment, data processing will carry out real-time control with control system to whole machine, and its control mode is mainly reflected in exhaust air rateSize is controlled.
The smell is monitored sensor (3) and needs to use specific control method, and its step is as follows：
1) smell monitoring function is manually opened；
2) smell monitoring sensor initializing, preheating time T, while obtaining air odor grade threshold values；The smell prisonThe span of initialization preheating time T of sensor (3) is surveyed at 5~10 minutes, its scope has fluctuation, it is necessary to according to realityThe working environment and sensor performance on border do appropriate correcting process.
3) judge whether present air has peculiar smell, if air free from extraneous odour, continues to run with this step, if air exist it is differentTaste, then into 4)；
4) start range hood fan, according to present air peculiar smell grade, regulating air volume；
5) judge whether peculiar smell is drained, is returned 3) if drained, if air also has peculiar smell, keep the step notBecome.
The air odor grade threshold values acquisition modes of smell monitoring sensor (3) are as follows：
1) electricity is gone up first, and the time starts timing, do not processed during preheating；
2) after the completion of preheating, the magnitude of voltage of feedback signal, the secondary data of record per second, continuous record 30 times, and handle are obtained30 this data carry out average value treatment, finally give a reference value V0；
3) per 30 secondary datas every other hour, are recorded again, data logging interval is still 1 second, and this data is put down 30Average value processing, finally gives a reference value V1, and V1 and V0 are compared, and judges that smaller value therein is defined as V0, and this V0 is newA reference value；
4) it is every just to carry out a step 3 every other hour in the case where not powering off).
It is described according to present air peculiar smell grade, the mode of regulating air volume is as follows：
1) a reference value V0 is obtained；
2) current data V-V0=△ V, by the size for judging the numerical value of △ V to control cigarette fan delivery；
3) 0 volt of ＜ △ V≤0.5 volt, cigarette machine does not run；
0.5 volt of ＜ △ V≤1 volt, cigarette machine opens 1 grade of air quantity；
1 volt of ＜ △ V≤1.5 volt, cigarette machine opens 2 grades of air quantity；
1.5 volts of ＜ △ V≤2 volt, cigarette machine opens 3 grades of air quantity；
2 volts of ＜ △ V, cigarette machine opens quick-fried air quantity；
4) step 3) scope there is fluctuation, it is necessary to do appropriate Corrections Division according to actual lampblack absorber overall performanceReason.
It is understood that it will be understood by those skilled in the art that being subject to technical scheme and inventive conceptThe protection domain of appended claims of the invention should all be belonged to replacement or change.
