Abstract
The utility model relates to a kitchen ventilator with a two layer air cover, and the main structure of the utility model is that an exhaust system forms an upward thermal current at the circumference of the oil fume, and a scavenger system forms a downward cool current at the outer circumference of the thermal current. Because of the principle of the molecular thermalmotion, the two currents produce mutual accelerated movement, which effectively controls the oil fume to diffuse. The utility model not only prevents the leakage of the oil fume, but also reaches the good effects of oxygen supplement and indoor temperature reduction.
Description
The utility model relates to a kind of smoke exhaust ventilator that utilizes double-layer air-flow to prevent the oil smoke diffusion.
The smoke exhaust ventilator that uses has certain smoke evacuation function at present, but because people's cooking custom makes oil smoke spread everywhere, so be difficult to oil smoke is excluded fully.
The precious smoke exhaust ventilator of section that has four patents, has been obtained good effect, but has been existed the cost height oil smoke sealing discharging with glass cabinet, is unfavorable for operation and needs problem such as cleaning at any time.
The purpose of this utility model is that a kind of smoke exhaust ventilator that can produce double-layer air-flow will be provided, and it is available double-layer air-flow sealing fume emission, and is replaceable again to fresh air and reduction indoor temperature.
The purpose of this utility model is to realize like this, this machine is made up of exhaust and two systems of ventilation, gas extraction system has changed traditional suction mode on oil smoke, utilize the strong updraft that self produces, around oil smoke, form three-dimensional air bell, with soot controlling therein, draw discharging.Air exchange system is drawn extraneous fresh air, form one downward strong cold airflow again in exhaust gas hood periphery, two strands of air-flows interact, the deep fat flue gas quickens to move upward, cold fresh air quickens to move downward, just form double-deck gas hood, control the leakage of flue gas fully at cooking stove and this machine peripheral space.
The utility model is because only need be with two smoking pipelines of former machine, change an exhaust into, a ventilation, so structure is simple especially, owing to utilize double-layer air-flow to stop the diffusion of flue gas, so do not influence user's operation, get rid of flue gas and replace outdoor fresh air again simultaneously, improved user's working environment greatly.
Schematic diagram is the profile of the double-layer air-flow hood ventilation apparatus that the utility model proposes.
Technical scheme below in conjunction with schematic view illustrating concrete enforcement of the present utility model.
This machine comprises: discharge duct (1), air refreshing tube (2), ventilation fan (3), ventilation sheet (4), exhaust sheet (5), exhaust fan (6), kitchen range (7).
The discharge duct of this machine (1) is positioned at the centre, its outlet is stretched out outdoor, exhaust sheet (5) is rectangular bar shaped, with kitchen range (7) four frame equal and opposite in directions, be in laterally zygomorphic position, air refreshing tube (2) with one of wall every, structure is identical cover above, air refreshing tube (2) import is installed in the below of discharge duct (1) outlet, and ventilation sheet (4) is on the sustained height with exhaust sheet (5), and exhaust fan (6) and ventilation fan (3) are installed in the centre of pipeline separately.
Claims (3)
1. double-layer air-flow hood ventilation apparatus, be primarily characterized in that: the discharge duct of this machine (1) is positioned at the centre of this machine, its outlet is stretched out outdoor, import exhaust sheet (5) is rectangular bar shaped, with kitchen range (7) four frame equal and opposite in directions, be in laterally zygomorphic position, air refreshing tube (2) with one of wall be separated by, structure is identical cover above, exhaust fan (6) and ventilation fan (3) are installed in the centre of pipeline separately.
2. smoke exhaust ventilator according to claim 1 is characterized in that the outlet of discharge duct (1), is positioned at the top of air refreshing tube (2) import.
3. smoke exhaust ventilator according to claim 1 is characterized in that, exhaust sheet (5) and ventilation sheet (4) are on the sustained height of kitchen range (7) top.
