Abstract
The utility model relates to a fission negative pressure kitchen ventilator with an air blower arranged on the outdoor wall, comprising a cover body, an aspiration channel, an air blower and an exhaust pipe; wherein the cover body is connected with the aspiration channel, while the air blower is arranged on the outdoor wall and connected with an air inlet pipe; wherein the air inlet pipe is intersected with the aspiration channel that extends out of the wall to form an exhaust pipe; according to the principle of hydrodynamics, the negative pressure out of the pressure difference that is produced by the fast flow of the wind power brings the oil and smoke that are exposed under the wind power into the exhaust pipe to be finally drained into the air flue or out of the door through the aspiration channel; because the oil and smoke do not pass through the air blower, the impeller is clean-free, thus greatly lightening the work load and prolonging the service life of the kitchen ventilator. In addition, due to the outdoor operation of the air blower, the indoor noise can be effectively reduced.
Description
Technical field
The utility model belongs to the smoke exhaust ventilator field, relates to a kind of blower fan and is arranged on split suction type smoke exhaust ventilator on the outdoor body of wall.
Background technology
Traditional smoke exhaust ventilator, its blower fan is arranged on and is integral structure in the hood, generally be installed in indoor kitchen gas stove top, oil smoke is in a large number attached on the fan blade during work, must often clean, waste time and energy, also can influence the service life of smoke exhaust ventilator, and the operating noise of blower fan is very big, is unfavorable for health.
Summary of the invention
The purpose of this utility model is to solve above-mentioned prior art problem and provides a kind of cleaning convenient, and noise is little, and blower fan is arranged on outdoor split suction type smoke exhaust ventilator.
The technical solution adopted in the utility model: a kind of split suction type smoke exhaust ventilator, comprise cover body, aspiration channel, blower fan, discharge pipe, connect aspiration channel on the cover body, blower fan is installed on the outdoor body of wall, its blower fan connects blast pipe, and the blast pipe aspiration channel outer with stretching out body of wall intersects and be merged into discharge pipe.
Described blast pipe passes flue and indoor aspiration channel and intersects and be merged into discharge pipe, and discharge pipe communicates with flue.
The axis angle of described blast pipe and aspiration channel is less than 30 degree.
Described aspiration channel, blast pipe and discharge pipe are overall structure.
Described aspiration channel, blast pipe and discharge pipe are linked by three-way pipe.
Blower fan of the present utility model is arranged on outdoor, and blast pipe and aspiration channel intersect, axis angle is less than 30 degree, according to fluid mechanics principle, utilizing the formed suction of pressure differential that produces that flows fast of wind-force is negative pressure, brings oil smoke into discharge pipe through aspiration channel under the effect of blower fan and enters flue or discharge outdoor; Because oil smoke is without blower fan, impeller can exempt to clean, and only needs at ordinary times to clean cover body, has alleviated the workload of cleaning greatly, and has prolonged the service life of smoke exhaust ventilator; Because blower fan at outside work, can effectively reduce room noise.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representations.
The specific embodiment
Embodiment 1
Consult shown in Figure 1ly, a kind of split suction type smoke exhaust ventilator comprises cover body 1, aspiration channel 2, blast pipe 3, blower fan 4, discharge pipe 5 etc.; Connect aspiration channel 2 on its cover body 1, aspiration channel 2 passes body of wall 6, and blower fan 4 is installed on the outdoor body of wall and is connected with blast pipe 3, and blast pipe 3 aspiration channel 2 outer with stretching out body of wall intersects and be merged into discharge pipe 5, and the axis angle of blast pipe 3 and aspiration channel 2 is less than 30 degree.Described aspiration channel 2, blast pipe 3 and discharge pipe 5 can be the global formation structure, also can be the split structure, select for use the prior art three-way pipe to link.
Embodiment 2
Consult shown in Figure 2ly, when the building that flue 7 is arranged is installed, blower fan 4 is installed on the outdoor body of wall 6, and blast pipe 3 is passed flue 7 intersect with indoor aspiration channel 2 and be merged into discharge pipe 5, discharge pipe 5 directly communicates with flue 7.All the other structures are with embodiment 1.
Operation principle of the present utility model: because blast pipe 3 is spent less than 30 with the axis angle of aspiration channel 2, according to fluid mechanics principle, utilizing the formed suction of pressure differential that produces that flows fast of wind-force is negative pressure, make the suction of the suction of discharge pipe 5, under the effect of blower fan 4, bring oil smoke into discharge pipe 5 and enter flue 7 or discharge outdoor through aspiration channel 2 greater than aspiration channel 2.
