CN2215689Y - Fume exhauster - Google Patents

Abstract

The utility model relates to a fume exhauster. The section of a shell body forms a right angle type. The arc face of the facade of the shell body is provided with an air inlet hole. A motor and an impeller are arranged on an upper top corner in the shell body whose lower part is an air discharging chamber. The fume exhauster changes the traditional top cap form of the fume exhauster. The normal of the wall for the installation of the fume exhauster can be narrowly made. Namely, the fume exhauster can be arranged close to a range with no influence of the cooking operation. The fume sucking efficiency can be obviously improved when the fume exhauster is close to the range.

Description

Fume exhauster

The utility model relates to the device of removing oil smoke in the kitchen.

Existing various smoke exhaust ventilator is the overhead guard formula, and hood-like body is installed on the cooking stove.Because the compressor flow size of smoke exhaust ventilator is only bigger near the influence of the air velocity the air entry, and the air velocity beyond the distance air entry 40cm is difficult to cause tangible influence.The flow velocity that overhead guard formula smoke exhaust ventilator utilizes the deep fat cigarette to rise more, but the diffusion of oil smoke limit rising edge must make hood-like casing more roomyly for improving oil suction cigarette efficient, and promptly the body outward flange is bigger apart from the distance of wall.Lower as the body installation, nearer apart from cooking stove, though the effect of oil suction cigarette is better, roomy body can hinder cooking operation.Higher as the body installation, the diffusion of rising oil smoke can exceed the area coverage of overhead guard, the blower fan gettering ability deficiency that then seems, and oil suction cigarette effect is not good enough.

The purpose of the utility model is to provide a kind ofly to be installed on apart from cooking stove nearerly, obviously improves oil suction cigarette ability, and does not influence the smoke exhaust ventilator of cooking operation.

It is the housing of square that described smoke exhaust ventilator has the cross section, the housing end face and the back side are the plane, the housing front upper is a cambered surface, motor and receded disk impeller are installed in the last drift angle place in the housing, open a plurality of lampblack-pumped air admission holes on the cambered surface in housing front, have dividing plate that impeller side is divided into inlet channel in the housing and communicate with air admission hole, dividing plate is divided into discharge chamber with lower housing portion and communicates with the exhaust outlet of impeller.

Described smoke exhaust ventilator is changed the traditional overhead guard form of smoke exhaust ventilator, the housing end face can design very narrowly, be that the housing outward flange is very near apart from wall, so that the body installation is very low can not to hinder cooking operation yet, it is air-breathing above the nearer side of distance cooking stove, and blower fan is enough to obvious influence is caused in the flow field of rising oil smoke.Through the actual test of the smoking mist of model machine, its effect is rather good, almost absolutely absorbs smog.Because the housing end face is the plane, and body can install lowlyer, and promptly the body end face also can be used as and puts the rack of putting condiment for cooking.

Housing 1 cross section is rectangular in shape, and housing 1 back side, end face are the plane, the housing front upper is a cambered surface, have a plurality of air admission holes 11 on the cambered surface, motor 4 receded disk impellers 3 are contained in the last drift angle place in the housing, dividing plate 5 is divided into inlet channel 2 with impeller 3 sides in the housing 1 and communicates with air admission hole 11, dividing plate 5 is divided into discharge chamber 6 with lower housing portion and communicates with the exhaust outlet 8 of impeller, the exhaust outlet 7 that can connect blast pipe is left in the side of discharge chamber 6, exhaust outlet 7 also can be reserved in the end face of impeller cavity of living in, i.e. housing end face.The base plate of discharge chamber 6 tilts, and opens oil dripping hole 10 at lowest part, and drawer type oil collection box 9 is housed under the oil dripping hole, and the periphery of housing end face is installed short fence 12, and making the body end face is rack, and the fence end face adds flat board again can become the multilayer rack.

Claims (3)
