Abstract

The utility model relates to a fume exhauster which is suitable for families especially. The utility model is characterized in that a fume outlet hole of a fume suction cavity is provided with an inner blowing pipe and a fume exhaust pipe, and the fume exhaust pipe is communicated with the inner blowing pipe across and is composed of side pipelines; the air inlet end of the inner blowing pipe is fixedly provided with a blower; in addition, the side pipelines are communicated between a side hole of the inner blowing pipe and a fume outlet hole of the fume suction cavity. Thus, the blower is free from fume pollution, the service life of a motor is extended, a fume exhaust cavity is smooth and the utility model has high fume exhaust efficiency.

Description

Differential smoke exhaust

The utility model relates to a kind of row and does not have the cigarette machine, especially in the smoke exhaust of family.

At present, smoke exhaust commonly used is directly at oil suction smoke chamber suction oil smoke with air exhauster, discharge through smoke discharging pipe then, because the oil smoke that is discharged from must pass through air exhauster (blade and motor), not only each assembly of air exhauster can be subjected to fume pollution, and the passage of oil smoke also is obstructed, and service efficiency is also lower.

In view of this, the purpose of this utility model provides a kind of differential smoke exhaust, blows air with the hair-dryer that is arranged in the smoke discharging pipe to exhaust opening, makes between smoke discharging pipe and oil suction smoke chamber and forms pressure reduction, makes oil smoke quicken directly to enter exhaust opening from the oil suction smoke chamber and discharges.

The purpose of this utility model is achieved in that it comprises oil suction smoke chamber and hair-dryer, it is characterized in that: the oil suction smoke chamber has into mouth and venthole, on the venthole of oil suction smoke chamber, be provided with the smoke discharging pipe that constitutes by gassing pipe and the crossing side pipe road that is communicated with thereof, wherein the two ends of gassing pipe are offered air inlet and exhaust opening respectively, and offer a side opening on its sidewall, hair-dryer is installed in the air inlet end, and the two ends in side pipe road are communicated with between the venthole side opening.

Above-mentioned venthole is opened in oil suction smoke chamber end face or side.

Above-mentioned side pipe road is straight type or curved pipeline.

Because adopt such scheme: hair-dryer is not contaminated, motor prolongs service life, and oil-discharging cavity is unobstructed again, mist extractor rate height, and noise is low in addition, power saving again, and cost is reduced greatly.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model first embodiment schematic diagram.

Fig. 2 the utility model second embodiment schematic diagram.

Fig. 3 the utility model the 3rd embodiment schematic diagram.

Among the figure: 1, oil suction smoke chamber 11, advance mouth 12, venthole 2, smoke discharging pipe 21, gassing pipe 211, air inlet 212, exhaust opening 213, side opening 22, side pipe road 3, air feeder 31, motor 32, blade

First embodiment comprises oil suction smoke chamber 1, smoke discharging pipe 2 and hair-dryer 3, as shown in Figure 1, and wherein:

Oil suction smoke chamber 1 has into mouth 11 and venthole 12, wherein enter the top position that mouth 11 is arranged on oil suction smoke chamber 1 bottom surface and rises over against oil smoke, and oil outlet 12 is arranged on oil suction smoke chamber 1 end face, belongs to prior art.

Smoke discharging pipe 2 comprises gassing pipe 21 and intersects the side pipe road 22 that is communicated with that wherein the two ends of gassing pipe 21 are offered air inlet 211, exhaust opening 212 respectively, and offer a side opening 213 on its sidewall; Side pipe road 22 is the two ends straight pipeline that is communicated with side opening 213 and venthole 12 respectively (can vertical or inclination smoke discharging pipe 2).

Hair-dryer 3 mainly is assembled into one by motor 31 and blade 32, belongs to prior art.The support of this motor 31 connects gassing pipe 21 air inlets 211 ends of smoke discharging pipe 2.

Second embodiment, as shown in Figure 2, the cigarette hole 12 of oil suction smoke chamber 1 is arranged on its side, and all the other structures are identical with first embodiment, so repeated description not.

The 3rd embodiment, as shown in Figure 3, side pipe road 22 is curved pipeline (as: quarter bend pipelines), if offer a plurality of ventholes 12 on the oil suction smoke chamber 1, can be communicated with many curved side pipe roads 22 respectively, to increase the mist extractor amount, all the other structures are identical with first embodiment, so repeated description not.

The operation principle of present embodiment is as follows:

When the motor 31 that starts hair-dryer 3, blade 32 is blown into outside air gassing pipe 21 and directly blows to exhaust opening 212, at this moment, side pipe road 22 forms pressure differential with gassing pipe 21, thereby quicken to guide the oil smoke that makes progress by oil suction smoke chamber 1 to flow, again without hair-dryer 3 towards exhaust opening 212 unobstructedly.
