Description

Side-absorption ventilator

Technical field

The utility model relates to range hood, particularly the range hood air inlet structure.

Background technology

At present, the range hood on the market roughly is divided into two kinds of end face air intake oil suction cigarette shown in Figure 1 and side air inlet formula range hoods shown in Figure 2 according to mounting means and air intake principle.The installation site of end face air intake range hood shown in Figure 1 is at the top of the kitchen range top, and air inlet is parallel to the kitchen range top, and vertical with body of wall, utilizes soot gas nature rising principle, absorbs oil smoke by end face air intake mode.The installation site of side air inlet range hood shown in Figure 2 is parallel or approximate parallel with body of wall, and air inlet is in the side of the kitchen range top, and near a pot limit, by the mandatory from the side absorption soot gas of mode closely.Two types range hood respectively has its pluses and minuses:

End face air intake range hood shown in Figure 1 is derived from Europe, be adapted to the culinary art custom that the European eats light, few oil smoke, with handsome in appearance, brief fashion, super high power is characteristics, and the principle of utilizing soot gas to rise is naturally absorbed oil smoke by end face air intake mode.This then can satisfy its culinary art demand fully for the European.But shortcoming is: air inlet from the pot face far away (with the pot identity distance from being generally 70cm); Culinary art custom by Chinese prosperous oily vigorous fire, quick-fried capsicum, a large amount of soot gas are in the process that rises, because of diffusion can make part oil smoke both sides or lateral direction escape to the left and right, therefore, end face air intake range hood shown in Figure 1 has only solved upward to the oil smoke that flows, and the oil smoke that subtend both sides or lateral direction diffusion are escaped has just been felt simply helpless, so it is relatively poor to absorb the ability of oil smoke; Common compensating mode is to increase power of fan, but power consumption is also increased thereupon.

Side air inlet formula range hood shown in Figure 2 is more suitable for Chinese culinary art custom, and (a distance pot limit is 10～15cm) usually, and the side air inlet mode rises oil smoke and just directly is forced to absorb by air inlet when also having little time to spread in in-plant installation; During fan operation, air-flow in exhaust fume collecting hood (2) cavity and the air-flow outside the exhaust fume collecting hood (2) can form negative pressuren zone because of the change of air pressure in the space of certain limit around the kitchen range top, oil smoke is tightly surrounded, and oil smoke can't be spread.These characteristics has determined side air inlet formula oil extracting machine shown in Figure 2 to have the ability of powerful absorption oil smoke.But not enough is: because air inlet is near the pot face, the installation site is lower, when a large amount of oil smoke produce, and ceaselessly stir the pot in food the time, can accelerate the rising and the diffusion velocity of soot gas, and the rate of climb is greater than the speed that spreads to the left and right, though most oil smoke are absorbed by in-plant air inlet, but the encirclement that a small amount of faster oil smoke of rising and diffusion still can break through negative pressuren zone, escape from air inlet top and left and right sides direction, it is not thorough that oil smoke is absorbed, and the kitchen pollution problem fails thoroughly to solve.

The utility model content

Technical problem to be solved in the utility model just provides a kind of range hood with end face air intake range hood and side air inlet formula range hood advantage.

The utility model solve the technical problem, and the technical scheme of employing is, side-absorption ventilator comprises panel, exhaust fume collecting hood, blower fan, and described panel is connected with exhaust fume collecting hood, it is characterized in that, described panel comprises side panel and top panel; Described side panel is provided with the side air inlet mouth, and described top panel is provided with the end face air inlet.

The beneficial effects of the utility model are, two kinds of functions of end face air intake and side air inlet range hood are combined together, both had the effect that side air inlet formula range hood is closely absorbed oil smoke, solved the problem that remaining oil smoke that the side air inlet range hood exists is upwards escaped again effectively, with end face air intake range hood and side air inlet formula range hood advantage, oil smoke is absorbed more thorough.And have do not meet and discuss, not oil dripping, characteristics such as handsome in appearance.

The specific embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.Side-absorption ventilator of the present utility model, the advantage of warm dexterously end face air intake and side air inlet range hood.

Referring to Fig. 3, Fig. 4.Side-absorption ventilator of the present utility model comprises panel 1, exhaust fume collecting hood 2 and blower fan 3.Panel 1 is made of side panel 11 and top panel 12.Side panel 11 is provided with side air inlet mouth 5, and top panel 12 is provided with end face air inlet 4.Panel 1 is connected with exhaust fume collecting hood 2, constitutes the inner air channel 20 of range hood, and blower fan 3 is connected with the exhaust outlet 6 of exhaust fume collecting hood.By the air transmission power of blower fan 3 in inner air channel, direction is mobile in accordance with regulations to make air, absorbs oil smoke.

Range hood of the present utility model, the panel 1 general sheet material that adopts is made through forming technology, and common used material has aluminium, cold-rolled steel sheet, corrosion resistant plate, reinforced plastic plate etc.For reducing processing technology, adopt integrally-built panel 1 usually, top panel 12 can be to be extended along camber line by side panel 11 to constitute, and forms arc-shaped transition at side panel 11 and top panel 12 intersections, both has been convenient to cleaning, and is also more attractive in appearance, and can prevent oil dripping.Make top panel 12 and side panel 11 slightly that the cambered surface of spill also can reach above-mentioned effect, particularly side panel 11 is made the slightly cambered surface of spill, can also enlarge the space of kitchen range top top, makes things convenient for cooking operation.

Range hood of the present utility model, also side panel 11 can be made plane or generally planar shape, the angle of side panel 11 and vertical direction (wall) is generally selected between 0～40 °, angle is big more, oil suction cigarette ability is strong more, but also can tie up kitchen range top space, preferable angle is about about 20 °.Top panel 12 also can be made plane or generally planar version, and between 55～85 °, angle is too big usually for the angle of top panel 12 and vertical direction, may produce oil dripping, and angle is too little then to be unfavorable for absorbing oil smoke, about 80 ° of preferred angle.

Owing to adopted two air intake directions of end face and side, the further improved technical scheme of the utility model is that side air inlet 5 and end face air inlet 4 are set up independent ventiduct separately, be convenient to control respectively and adjust the intake of side air inlet mouth 5 and end face air inlet 4, reach according to different culinary art forms the purpose of rationally controlling range hood work and saving the energy.Two independent ventiducts can converge at air outlet 6 places, use 1 typhoon machine 3 to carry out work, also can respectively execute the intake that its duty is controlled side air inlet mouth 5 and end face air inlet 4 respectively for two independent ventiducts respectively are provided with a typhoon machine.
