Description
Technical field
The present invention relates to a kind of exhaust kitchens of built-in vent device.
Background technology
Kitchen is the element of house, is that people carry out the movable main place of cooking.Due to various civilian combustions
Material burning, cooking fume and house refuse etc. make kitchen become " severely afflicated area " of house, and it is dirty that kitchen also becomes local-style dwelling houses room air
One of important sources of dye.Kitchen exhaust gas is most important polluted gas in kitchen, it includes two kinds：First, fuel combustion process
The exhaust gas of release, second is that food and grease carry out substance caused by a series of physical chemical change at high temperature.Two kinds of substances
It spreads in spatial mixing and rapidly, endangers the physical and mental health of people.
Most important ingredient is alkane and alkene, followed by organic acid, aldehyde compound and polycyclic aromatic hydrocarbon in cooking fume.
Although aliphatic hydrocarbon is not carcinogen, hendecane, dodecane, octadecane etc., which are important, promotees cancer substance；Phenols, polycyoalkane
Also there is tumor promotion；Aldehydes has mutagens.
In general local-style dwelling houses man, kitchen ventilation generally only considers air draft, and mending wind then is freely covered by door, window, with
Balance cylinder's inside and outside differential pressure.With the intensification that people recognize indoor air quality, kitchen ventilation and soot controlling also gradually cause
The concern of people.
In the prior art, two ways is used at present.It is to be made using indoor and outdoor temperature difference one is gravity-flow ventilation
At hot pressing or wind-force effect caused by wind pressure realize a kind of draft type of ventilation.Its ventilation volume is very big, does not consume electricity
Can, it is noiseless, it is a kind of most economical draft type.But this method air draft is easy by atmospheric factors such as wind direction and wind speed
It influences, air draft ability is also extremely unstable, is susceptible to oil smoke and passes through phenomenon, cannot meet and discharge oil smoke and pernicious gas in a organized way
Requirement, be generally widely used in rural area low-rise building.
Another kind is force ventilation.Force ventilation is to make full use of the Thermal plume formed in gastronomical process, is existed in conjunction with wind turbine
Outdoor, control air is discharged by ventilation power (ventilation fan or smoke exhaust ventilator) by the negative pressure that cooking stove top is formed for kitchen exhaust gas
Pollutant is to the other regional diffusions in kitchen.Mechanical exhaust is divided to two kinds, first, dividing family direct emission mode, such mode is simple, row
Air quantity is larger.But it has several drawbacks in that：First, the smoke exhaust pipe and wind-proof cap that user voluntarily picks out are multifarious, and it is outer to destroy building
The beauty of facade；Secondly, the oil smoke of lower layer kitchen discharge can enter the interior of upper layer resident, pollute；Furthermore when encountering height
When fast head-on wind, it may appear that exhaust is unsmooth or phenomenon is poured in down a chimney in generation.Second is that concentrating discharging modes.When kitchen ventilation systems are opened
Afterwards, kitchen ventilation must be compensated for.If not enough fresh airs compensate kitchen ventilation amount, the pressure in kitchen can be less than outdoor
Pressure causes kitchen fuel combustion insufficient and smoke exhaust ventilator efficiency is reduced, cannot be discharged in gastronomical process and produce in time
Raw nuisance.In commercial kitchen, mechanical makeup air is generally used, and its technology is also more ripe.In local-style dwelling houses kitchen, wind form is mended
Consider seldom, the supplement of fresh air is mainly by the infiltration of door, window.But due to modern architecture wall air-tightness, thermal insulation
It can enhance, rely solely on door and window benefit wind and obviously have been unable to meet requirement, oil smoke harm and the ventilation in local-style dwelling houses kitchen cause height
Concern.Studies have shown that kitchen range position, draft organizational form, architectural design form are to kitchen ventilation and smoke pumping in kitchen
Machine cleaning efficiency all has a significant impact.
For this purpose, (these art applications people has largely carried out specially in before applicant it is proposed that excessively several exhaust kitchen
Profit application, forms certain patent distribution), but in these techniques, be substantially to one fixed point direction of hearth progress
Oil smoke aspirates, and does not carry out taking into account smoke pumping from upper and lower both direction, causes smoke pumping inefficient to a certain extent, aspirates
Sordid situation, as a result, applicant devise again it is a kind of up and down integrated form smoke pumping kitchen, such as Fig. 1 institutes.In the technology
In, it is assembled according to mode shown in Fig. 1, air-flow is flowed by diagram direction, after exhaust apparatus starts, inside kitchen
Soot gas through in the filter devices at different levels sorbing material adsorption filtration after through being discharged to outside kitchen.Due to oil smoke air
Adsorption filtration is have passed through, so the pollution to air can be further decreased；Further, since using the side of top oil smoke suction
Formula further improves oil smoke suction effect；
But in production application, actual monitoring is carried out by monitoring device and finds that the technology has two：
First, although being aspirated to the exhaust kitchen top oil smoke, the oil smoke after all suctions is through a pipeline
That is it is discharged after the 5th connecting pipe 19 convergence, this adds increased the oil smoke flows in the 5th connecting pipe, in practical cooking process
In, the power consumption of scavenger fan can be caused larger instead, the power consumption of especially the first auxiliary exhaust fan 17 is excessive；
Second, the first class purification equipment 10 is interior to be equipped with porous filtering ceramic body；The preparation packet of the porous filtering ceramics
Powder preparation, compression moulding, high temperature sintering are included, is that porous filtering ceramic body is directly placed at first class purification during the installation process
In equipment 10, both ends are fixed strainer (such as non-woven fabrics) plain mode using simple bayonet form or screw and are fixed,
This installation fixed effect is not very firm, it is easy to the breakage of porous filtering ceramic body under external force is caused, to cause
The unnecessary economic loss of user.
