Description

Smoke exhaust ventilator

One, technical field:

The utility model relates to a kind of smoke exhaust ventilator, and particularly a kind of smoke exhaust ventilator with oil separation function belongs to a kind of family kitchen ventilation equipment.

Two, background technology:

At present, generally adopt smoke exhaust ventilator at urban family, kitchen ventilation equipment.General smoke exhaust ventilator comprises exhaust fume collecting hood, air-suction channel, air exhaust passage, switch and blower fan, and wherein blower fan is installed between air-suction channel and the air exhaust passage, sucks through air exhaust passage discharge outdoor through air intake passage the oil smoke mist when blower fan starts again.Existing this smoke exhaust ventilator is directly discharged the oil smoke mist outdoor, and environment is caused great pollution.

Three, technical scheme:

The purpose of this utility model is the problem of environment pollution caused that exists in the existing smoke exhaust ventilator in order to solve, and a kind of simple in structure, environmental-friendly kitchen ventilator that can effectively separate oil smoke is provided.

The utility model adopts following technical scheme: a kind of smoke exhaust ventilator, comprise housing, motor, impeller, air inlet, exhaust outlet, switch, it is characterized in that: housing has forward and backward bin, impeller is two, impeller in the preceding bin of housing is that oil smoke separates impeller, and the impeller of back bin is the exhausting impeller, and the preceding bin of housing has an annular oil trap.

The utility model adopts annular oil trap and bilobed wheel structure, can effectively separate oil smoke, discharges gas environment is not had any pollution.

Four, description of drawings:

Fig. 1 is a structure chart of the present utility model.

Five, the specific embodiment:

The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings below:

As can be seen from Figure 1, the utility model comprises housing 1, motor 4, impeller, air inlet, exhaust outlet, switch, housing 1 has forward and backward bin, impeller is two, impeller in the preceding bin of housing 1 is that oil smoke separates impeller 2, and the impeller of back bin is an exhausting impeller 5, separates on the impeller 2 at oil smoke and posts oil suction object 4, the preceding bin of housing 1 has an annular oil trap 8, and the import and export radius of annular oil trap 8 separates the radius of impeller 2 less than oil smoke.Oil-drain pipe 7 and movable bunker 6 are arranged under the preceding bin of housing 1.

When the utility model is used in the bigger environment of oil smoke concentration, can also increase the number that oil smoke separates impeller, realize that multistage oil smoke separates.

Operation principle: after starting smoke exhaust ventilator, oil smoke enters through air inlet, separates under impeller 2 effects at the oil smoke that posts oil suction object 4, and the oil smoke that mist of oil is rotated separates oil suction object 4 absorption on the impeller 2, and cigarette is discharged through exhaust outlet by exhausting impeller 5.Be adsorbed on oil smoke and separate mist of oil on the impeller 2 under action of centrifugal force, be thrown toward annular oil trap, inflow activity bunker 6, or discharge by oil-drain pipe 7.
