Description
Technical field
The present invention relates to kitchen utensils field, more specifically, relate to a kind of eddy flow without leaf oil fume eliminator and comprise the range hood of this eddy flow without leaf oil fume eliminator.
Background technology
Come out so far from first generation range hood, blower fan system is the core of range hood all the time, and what current lampblack absorber used substantially is all centrifugal blower, and principle utilizes the centrifugal action in flabellum rotation process, by outside soot gas mechanically discharge chamber.The application of this blower fan system on cigarette machine is relative to very ripe other blower fans, but the drawback of this system is quite a few, as difficult in flabellum cleaning, noise large, along with passage of time smoking effect decline, in spiral case greasy dirt accumulation there is long-pending large, the outward appearance of potential safety hazard, cigarette body unsightly etc., these problems along with society rapid advances and Internet era arriving, annoying each family and Yan Ji manufacturer.
For solving the drawback of above-mentioned blower fan system, air amplifier is utilized to solve oil smoke problem in correlation technique, but just simply apply mechanically traditional air amplifier, do not consider the efficiency of airflow injection completely, this traditional air amplifier is lower to compressed-air actuated utilization rate, directly be applied in the smoke absorption effect that range hood effectively can not promote range hood, and a large amount of compressed air can be wasted, thus cause the efficiency of whole oil smoke emission system to reduce; And high pressure draught directly clashes into the inwall of air amplifier, noise when causing range hood to work is comparatively large, does not therefore substantially solve the problem of smoke absorption effect and efficiency.
Summary of the invention
The present invention is intended at least to solve one of technical problem existed in prior art.
For this reason, the object of one aspect of the present invention is, provides one effectively to promote smoke absorption effect, and compressed-air actuated utilization rate is high, noise is little, the eddy flow of easy cleaning is without leaf oil fume eliminator.
The object of another aspect of the present invention is, provides a kind of and comprises the range hood of above-mentioned eddy flow without leaf oil fume eliminator.
For achieving the above object, the embodiment of one aspect of the present invention provides a kind of eddy flow without leaf oil fume eliminator, for range hood, comprise: vortex lead jetting device, described vortex lead jetting device ringwise, and has annular channel, is tangentially provided with air inlet along outside wall surface on the outer wall of described vortex lead jetting device, along the gas outlet being circumferentially with annular of internal face on the inwall of described vortex lead jetting device, described gas outlet is connected with described air inlet by described annular channel.
The eddy flow that the above embodiment of the present invention provides is without leaf oil fume eliminator, comprise vortex lead jetting device, tangentially air inlet is provided with along outside wall surface on the outer wall of vortex lead jetting device, air inlet is connected with the compressed-air actuated air compressor machine of generation, when using eddy flow without leaf oil fume eliminator, compressed air flows in vortex lead jetting device by air inlet, because air inlet is tangential admission mouth, this just makes air-flow after this tangential admission mouth enters vortex lead jetting device, circle round in annular channel and form the annular airflow of High Rotation Speed, this annular airflow rotates from the annular air outlet of vortex lead jetting device and flows out, due to the wall attachment effect of fluid, rotate the annular airflow that the flows out internal face along vortex lead jetting device with High Rotation Speed upwards flowing gradually, swirling eddy is made to be inverted cone-shaped or V-shaped, as cyclone, rotary pneumatic fails to be convened for lack of a quorum and drives rapidly surrounding air flowing, thus produce very high negative pressure at the center of vortex lead jetting device, the rotational flow of annular airflow makes negative pressuren zone move down further, pressure due to now soot gas is greater than the pressure of negative pressuren zone, soot gas is driven in the swirling eddy entering and continue to be formed, and then be expelled to outdoor by external pipeline, make eddy flow good without the smoke absorption effect of leaf oil fume eliminator, compressed-air actuated utilization rate is high, and structure is simple, the noise produced during work is little.
Specifically, the eddy flow that the above embodiment of the present invention provides is without leaf oil fume eliminator, air inlet is along the tangential setting of the outside wall surface of vortex lead jetting device, make compressed air tangentially can enter annular channel along the outside wall surface of vortex lead jetting device, and form the annular injection air-flow of High Rotation Speed along the direction flowing of annular channel, slow down the shock of the wall of compressed air and vortex lead jetting device, thus decrease the compressed-air actuated energy loss caused because of shock, compressed-air actuated flow velocity reduces, and the change of compressed air flow direction, thus the compressed-air actuated speed that improve from gas outlet ejection, and make compressed air rotate outflow in the same direction, thus enhance the flow velocity of swirling eddy, more surrounding air is driven and flows in annular airflow, thus extremely strong negative pressuren zone is formed centrally in vortex lead jetting device, obviously improve the intensity in central negative pressure district, and negative pressuren zone is moved down further, thus make negative pressuren zone closer to the kitchen range top, the pressure of the soot gas produced when gas kitchen ranges is worked is greater than negative pressuren zone pressure, thus drive soot gas High Rotation Speed and enter in the swirling eddy continuing to be formed, and then soot gas can be discharged smoothly by external pipe, enhance smoke absorption effect, and improve compressed-air actuated utilization rate, reduce the noise produced because of the wall of compressed air shock vortex lead jetting device simultaneously, and provide compressed-air actuated air compressor machine can be external, noise during to reduce culinary art further in kitchen, thus effectively ensure that smoke absorption effect, compressed-air actuated utilization rate, and noise when effectively reducing culinary art in kitchen, and do not need in the application to use complicated blower fan system, thus avoid and adopt complicated blower fan system and the range hood volume that causes is large, the difficult cleaning of flabellum, noise pass degradation drawback under smoke absorption effect greatly, in time.
It should be noted that, the eddy flow that the application provides can be arranged on the top of gas kitchen ranges without leaf oil fume eliminator, thus makes the negative pressuren zone be formed centrally in vortex lead jetting device closer to the kitchen range top, and then is convenient to the smooth discharge of soot gas; Compressed air used in this application can be provided by mini air compressor or other air-pressure equipment, and goes out on precipitators without leaf, for it provides high pressure injection air-flow through piping access eddy flow; Because the application does not relate to the blower fan system that traditional range hood uses, make soot gas without the flabellum of complexity and spiral case, thus do not have a cleaning difficult problem and exist; And because integral cyclone is very little without the volume of leaf oil fume eliminator, therefore can be embedded in cabinet, also can be designed to the ornament in kitchen, thus effectively be improved the aesthetics in kitchen.
