Abstract

The utility model relates to a high-efficiency energy-saving cooking fume removing machine whose part space can form a rotary wind field. The utility model is characterized in that an air-blow inlet pipe (11) is arranged above a machine shell; an air-jet guide pipe (10) is arranged in the machine shell (2); the outside of the lower wall face of the machine shell (2) is provided with an air-jet main pipe (3) which is provided with a plurality of holes and nozzles (1) whose number is equal to that of the holes; the air-blow inlet pipe (11) forms an air-jet channel with the air-jet guide pipe (10) and the air-jet main pipe (3) through the cavity of a blower fan (9). The cooking fume can receive extensive negative pressure action and can be forced to rise and to be exhausted out of the room through an air outlet under the action of both the forced rotation wind formed by the nozzles on the circumference under a fume hood.

Description

Cooking fume removing machine

The utility model relates to a kind of kitchen ventilation equipment, specifically a kind of cyclone type smoke exhaust ventilator that can produce the rotation air curtain.

All kinds of smoke exhaust ventilators of mass selling on the existing market, no matter be single air channel, or double air channel, owing to require to be higher than people's head when installing, in order to avoid meet and discuss, therefore often be installed in from kitchen range top far away, like this oil smoke that produces in the kitchen range some can still can pollute to transpiration all around indoor environment.In order to improve the mist extractor rate, pollution abatement, people have proposed some feasible technical schemes to existing smoke exhaust ventilator, have announced a kind of " the efficient smoke-cleaning heat-insulation smoke exhaust ventilator of wind curtain type " as Chinese patent CN2090494U, can form downward air curtain around smoke exhaust ventilator, the smoke pumping effect is better, but this air curtain is extended downwards significantly, the bigger air blast of power just must be set, caused whole smoke exhaust ventilator power to increase so again, thereby increased power consumption, noise also increases thereupon.

The purpose of this utility model is exactly that a kind of female pipe of spray wind nozzle that is provided with downward extension will be provided.Can form the whirlwind field of a sealing, thereby can effectively improve clean cigarette rate, reduce blower power, saves energy, the smoke exhaust ventilator of reduction noise.

The purpose of this utility model is achieved in that the cyclone type smoke exhaust ventilator is by casing (2), oil extraction smoke pipe (4), fume exhaust cover (5), ventilating fan (6), motor compositions such as (7), oil extraction smoke pipe (5) forms the mist extractor passage by the cavity and the oil extraction smoke pipe (4) of ventilating fan (6), motor (7) drives ventilating fan (6) rotation by power transmission shaft, its special feature is to be provided with in the top of casing (2) a blast entrance pipe (11), in casing (2), be provided with a spray wind conduit (10), in casing (2) lower wall surface arranged outside the one spray female pipe of wind (3) is arranged, blast entrance pipe (11) forms a spray wind passage by the cavity of blower fan (9) with spray wind conduit (10) and the spray female pipe of wind (3).

The two ends of the spray female pipe of wind (3) can be sealed, on it, have several holes, nozzle (1) with hole equivalent is installed, side at nozzle (1) offers a strip gab, also can be several apertures that a bar shaped distributes, and the opening direction of each nozzle (1) all point to next nozzle (1).

Blower fan (9) can be to drive rotation by the transmission device transmission by motor (7), also can be a motor direct-drive rotation is installed separately.

When blower fan (9) was driven by motor (7) by transmission device, its kind of drive can be a belt transmission, also can adopt gear type or other kind of drive.

Because the utility model is provided with the one group of female pipe of the spray wind that extends nozzle downwards, the blower fan that smaller power so only need be set can form a rotation wind field in the smoke exhaust ventilator bottom, the firm rising of oil smoke just can enter in this rotation wind field at once, can not spread, low because of intermediate pressure simultaneously, under the effect of ventilating fan, oil smoke can be extracted out fully, and the whirlwind field increased the smoke pumping space greatly, be equivalent to reduce the distance of fume exhaust cover and kitchen range, so the utility model is not only energy-conservation but also efficient.

Because the utility model has formed air curtain in certain space, like this kitchen there is the good protection effect again.Simultaneously to external world as outside window wind has the effect of necessarily resisting.

Fig. 1 is the utility model structural representation.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is a fundamental diagram of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:

The utility model key is to utilize the nozzle of several particular design to form the rotation wind field, obligates oil smoke.

Referring to Fig. 1.The cyclone type smoke exhaust ventilator is by casing (2), oil extraction smoke pipe (4), fume exhaust cover (5), ventilating fan (6), blower fan (9), blast entrance pipe (11), motor compositions such as (7), motor (7) is ventilating fan (6) by driving-belt (8), blower fan (9) provides power simultaneously, also can add a motor is that blower fan (9) provides power, oil extraction smoke pipe (4) and blast entrance pipe (11) are contained in the top of casing (2), fume exhaust cover (5) is contained in casing (2) below, fume exhaust cover (5) connects ventilating fan (6) cavity and forms the mist extractor passage with oil extraction smoke pipe (4) again, blast entrance pipe (11) and blower fan (9) cavity are managed (3) with spray wind mother again with spray wind conduit (10), nozzle (1) forms spray wind passage, spray wind conduit (a 10) part is in casing (2), a part is outside casing (2), the spray female pipe of wind (3) is close under the casing (2), nozzle (1) combination is installed on the spray female pipe of wind (3), and casing removes oil extraction smoke pipe (4), fume exhaust cover (5), spray wind conduit (10), blast entrance pipe (11) is outer to be the combination sealing space.

Referring to Fig. 2.With 9 bar shaped nozzles (1), only use two by wall, nozzle length is 30cm, wide 2mm, one in front is short slightly, is approximate garden awl projection line, wherein by two on wall near living wall, be " " shape, the nozzle air current direction is alignd with next root, so can form clockwise or be rotated counterclockwise wind field directly over kitchen range.
