Affiliated technical field
The utility model relates to a kind of semi-enclosed smoke exhaust ventilator, and is more precisely that cooking stove is semiclosed and adopt dense material to filter the smoke exhaust ventilator of oil smoke, belongs to household appliance technical field.
Background technology
Take out (inhale, remove, row) lampblack absorber at present mainly by blower fan, screen pack, catchment cup, gauge tap, casing be installed in apart from the parts such as range hood of cooking stove top certain distance and constitute.Range hood is installed in the casing lower edge, and the range hood of multiple smoke exhaust ventilator and casing are one.Hope produces air-flow by blower fan, forms one air-flow from bottom to top by range hood control airflow direction, utilizes air-flow that oil smoke is sent into air inlet, and air-flow leaches oil smoke and flow into catchment cup through filter screen before entering blower fan.
The major function of smoke exhaust ventilator is with oil smoke suction lampblack absorber, promptly high smoke pumping efficient.And the smoke exhaust ventilator structure that adopts at present, air is may the direction diffusion flow to air inlet from all, and is not simple flowing from bottom to top.Oil smoke mainly flows to air inlet by the trend that hot-air rises naturally, is difficult to avoid the interference of side direction wind.At present, multiple lampblack absorber all will improve the air quantity of blower fan as the effective way that improves smoke pumping efficient, and the air quantity of multiple lampblack absorber all surpasses per minute 13m
3, power of fan is more than 200 watts, but still can not prevent that oil smoke from flying away everywhere.
Another function of smoke exhaust ventilator is the filtration to oil smoke.The employed screen pack of smoke exhaust ventilator aperture is bigger at present, the part oil smoke still can pass through screen pack, and the high more smoke particle of wind speed is difficult more attached on the screen pack, causes the part oil smoke to enter smoke exhaust ventilator inside, has polluted smoke exhaust ventilator, blast pipe and public smokejack.Cleaning fan of sucking oil fume has become user's a difficult problem at present, and the mediation of public smokejack may be potential more hang-up.Filter the purpose that can reach filter absolute oil cigarette with dense material, but certainly will make air quantity, wind speed decreased, influence smoke pumping efficient.In a word, improve smoke pumping efficient and become two problems that condition each other with the raising filtering function.
Summary of the invention
In order to guarantee that oil smoke can almost all enter smoke exhaust ventilator, promptly high smoke pumping efficient can filter out the oil smoke overwhelming majority again, reaches the target that smoke exhaust ventilator exempts to unpick and wash, and the utility model provides a kind of semi-enclosed smoke exhaust ventilator.
The technical solution adopted in the utility model is: a semiclosed cover is installed to replace the range hood of present smoke exhaust ventilator around cooking stove on the cooking stove table top.Connect under the semiclosed cover cooking stove table top, on the shell of meeting sb. at the airport, an actuating doors is opened in the front portion, forming one only can be by actuating doors and the extraneous little space that communicates.Casing is from being equipped with filtering oil smoke net and catchment cup, dense material filter membrane and support, blower fan and exhaust duct down.Be the air quantity that raising is passed through, the large tracts of land filter membrane and the screen pack that are designed to plane or curved surface cover whole casing lower edge openings.Blower fan disposes overcurrent protective device and indicator lamp.Gauge tap, indicator lamp, illuminating lamp are positioned at the actuating doors top.The top panel of semiclosed cover actuating doors adopts transparent material, with as cooking, observation window when cooking.
The effect of semiclosed cover is that the oil smoke range of scatter is narrowed down to space in the seal bootr from whole kitchen space, and the limit air flow route is for to enter from actuating doors, upwards float liter after taking away oil smoke, flow out from the blower fan outlet again, oil smoke source (pot) is among air glide path, and this makes oil smoke be difficult to leak.
The filtering oil smoke net tentatively filters oil smoke, makes big smoke particle adhere to it on and flows into catchment cup, to reduce oil smoke the pickup of filter membrane is prolonged the time of the each use of filter membrane.
The dense material filter membrane carries out the fine filtering second time to oil smoke, and tiny smoke particle can both be filtered.Capable of washing or the replacing of dense material filter membrane.
Bleed the power of blower fan as long as guaranteeing to make by its swabbing action behind filter screen and the filter membrane is negative pressure mutually to external world in the semiclosed cover, promptly guarantee air can by actuating doors enter seal bootr naturally and can not be in the seal bootr to outside mobile.Because filter screen and filter membrane area are very big, though the filter membrane aperture is very little, its air quantity that can pass through is still relatively large, thereby has reduced the requirement to power of fan again.
Can cause the blower motor overcurrent when filter membrane stops up because of fume pollution, when overcurrent reaches preset value, protector will be controlled blower fan and can't start, and open the indicator lamp notice and change filter membrane.
The beneficial effects of the utility model are: make oil smoke be difficult to leak, the overwhelming majority is inhaled into smoke exhaust ventilator; Can filter out oil smoke effectively, lampblack absorber inside, public smokejack are not polluted, and only need seal bootr inwall, screen pack, catchment cup are regularly cleaned, filter membrane be cleaned or changes by indicating reminders.
Further specify structure of the present utility model and operation principle below by embodiment and accompanying drawing.
Fig. 1 is the profile of semi-enclosed smoke exhaust ventilator, and Fig. 2 is the longitudinal section schematic diagram of semi-enclosed smoke exhaust ventilator.1 for being equipped with blower fan in the exhaust outlet of casing, its inside among the figure; 2 chassis bodies; 3 semiclosed covers, it only has the actuating doors of suitable height with the back of cooking stove, two side-closed at the positive basifacial of cooking stove, and panel above the actuating doors adopts transparent material, the observation window when cooking; 4 cooking stove table tops; 5 gauge taps and indicator lamp; The positive observation window of 6 semiclosed covers; The positive actuating doors of 7 semiclosed covers; 8 cooking stoves; 9 quick detachable filtering oil smoke nets; 10 catchment cups; 11 quick detachable corrugated filtering oil smoke film and supports thereof, filter membrane can be with fire-retardant cloth manufacturing; 12 illuminating lamps.
Fig. 2 has also represented the flow direction of air-flow.If regard whole smoke exhaust ventilator the breather line of a thickness inequality as, then actuating doors is its import, and the casing exhaust outlet is its outlet, and oil smoke source (pot) is among this pipeline.So, all constantly entering up and down from actuating doors as long as maintain air, oil smoke just is difficult to reveal, so this structure can reduce the requirement to fan delivery.In addition, undulatory filter membrane can be than several times of plane filter membrane enlarged areas, and filter membrane also can alleviate the load of blower fan through the increase of air ability.
