Abstract

The utility model relates to a cooker hood with an air flow enhancer. The cooker hood with an air flow enhancer comprises an exhaust fan and a horizontal type trapezoid exhaust box body. The exhaust fan is arranged on the big end face of the horizontal type trapezoid exhaust box body. An air inlet is respectively arranged on both sides of the exhaust fan. The small end face of the trapezoid exhaust box body is an air outlet. The utility model has the advantages of simple structure, easy manufacture, convenient utilization, notable effect of smoke pumping, cleanness and convenience.

Description

The afterburning fume exhaust device of air-flow

The utility model relates to a kind of kitchen oily fume exhauster, the afterburning fume exhaust device of particularly a kind of air-flow.

Because oily fume exhauster can reduce oil smoke to indoor pollution, and has created the operating environment of a health to the kitchen, thereby has obtained widespread usage.But existing oily fume exhauster is owing to the problem in the design, and it can not all be got rid of oil smoke, and is particularly more outstanding when carrying out Fried, fried, cooked, fried on kitchen range, becomes the weak link on the oily fume exhauster function.Oil smoke is still perplexing huge numbers of families.

The purpose of this utility model is to provide a kind of air-flow afterburning fume exhaust device.

The utility model adopts technical solution as described below: the afterburning fume exhaust device of air-flow, comprise ventilating fan, also comprise a horizontal trapezoidal fumer body, large end face at trapezoidal exhaust casing is equipped with ventilating fan, respectively there is an air inlet both sides of ventilating fan, and the small end face of trapezoidal exhaust casing is the gas outlet.

One system stream plate is arranged in the upper edge of trapezoidal exhaust casing large end face.

At air inlet air door is housed.

One air regulating board is arranged in right air inlet.

The bottom surface of trapezoidal exhaust casing and the angle of vertical direction are 60 °-75 °.

For the utility model, after ventilating fan was opened, the waste gas stream that institute's pump drainage goes out passed through trapezoidal channel at high speed, thereby produces negative pressure on the both sides of air flow stream.Because the gas outlet goes out a large amount of high-speed exhaust gas,, and can only be jealous of the gas before the kitchen range to suck the trapezoidal channel negative pressuren zone rapidly from the air inlet handle of ventilating fan side so outdoor air can't enter the trapezoidal channel negative pressuren zone.Ventilating fan continues running, and this dynamic balance down will continue, and obviously also just enlarges and quickened the effect of pump drainage oil smoke.The waste gas of ventilating fan pump drainage is added the gas that is entered by air inlet, all gathers around to the gas outlet simultaneously.Because gas density strengthens, thereby its gas flow rate that passes through the gas outlet is accelerated, made the ventilating fan faster rotational speed conversely again, also will strengthen the soakage of air inlet to air simultaneously, its direct effect is to have strengthened the oil smoke amount of pump drainage.

Advantage of the present utility model is: 1, the door and window in kitchen can often be opened, and does not influence mist extractor, so kitchen ventilation is good, bright, free from extraneous odour.When 2, ventilating fan operates, pump drainage oil smoke promptly, intimate being controlled at all in the confined space that constitutes by air door and system stream plate of residual oil smoke of having only minute quantity, promptly be controlled at the ventilating fan periphery, thereby, oil stain also only is apparent near the ventilating fan down either side, and it is very convenient to clean, and realizing does not have greasy dirt outside oil stains-less, the kitchen in the kitchen.3, simple in structure, easy to manufacture, easy to use, cleaning easily, effect is remarkable.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the utility model structural representation

Fig. 2 is the right view of Fig. 1

Fig. 3 is the three-dimensional appearance schematic diagram of Fig. 1

Fig. 4 is the vertical view of Fig. 1

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, have a trapezoidal cabinet 8 to be horizontal placement, it is trapezoidal exhaust casing 8, the large end face of trapezoidal exhaust casing 8 is preceding, small end face after, large end face communicates with small end face.At large end face a ventilating fan 1 is housed, in the both sides of ventilating fan 1 air inlet 3,9 is arranged respectively, on each air inlet 3,9 air door 4,10 is arranged respectively, on the left side in right air port 3 and with ventilating fan 1 joint one air regulating board 5 is arranged, air regulating board 5 stretches to the sidewall of trapezoidal exhaust casing 8, it and sidewall do not join and leave a narrow slit, and the big I of narrow slit is regulated by air regulating board 5, and air regulating board 5 is fixing by guide groove 6.In the upper edge of trapezoidal exhaust casing 8 large end faces, a system stream plate 2 just is housed above ventilating fan 1, two air inlets 3,9, system stream plate 2 is a rectangle.The small end face of trapezoidal exhaust casing 8 is gas outlet 7.

Referring to Fig. 2, trapezoidal exhaust casing 8 downward-sloping 20 °, the under casing face of just trapezoidal exhaust casing 8 and the angle of vertical direction are 70 °.

When using the utility model, it is installed in cooking stove before.
