Abstract
The utility model relates to a vortex ejection type cooking fume exhauster with an external fan. The utility model is composed of a cooking fume hood (1), a vortex generator (2), a discharge flue (3) and the fan (4), wherein, the cooking fume hood (1) is connected with the vortex generator (2) which is connected with the discharge flue (3) to form a cooking fume airflow channel; the fan (4) is arranged out of the cooking fume airflow channel; an air outlet of the fan (4) is connected with the vortex generator to form rotating-shaped airflow which can cause cooking fumes produced by cooking to be fast and cleanly exhausted to achieve an ideal cooking fume exhausting effect. The utility model is practical household sanitary equipment.
Description
The utility model relates to a kind of smoke pumping equipment for kitchen use, the external vortex injection type of particularly a kind of blower fan smoke exhaust ventilator.
In the prior art, being applied to the domestic hygiene smoke exhaust ventilator is by range hood, and air exhauster and smokejack are formed, air exhauster normally is installed in the floss hole in the range hood, this smoke exhaust ventilator smoke pumping effect is not ideal enough, and greasy dirt often sticks on the draught fan impeller, and cleaning is difficulty very.In order to address this problem, people have designed the scheme of various solutions, patent 96220549.4 provides " the family expenses injecting type is cleaning fan of sucking oil fume not ", patent 97213171.x provides " a kind of injection type smoke exhaust ventilator ", more than these technology blower fan and fume pipeline are separated, certain improvement is arranged, but its blower air pipe outlet stretches in fume pipeline, cleaning is difficult, has dwindled the free air space of fume pipeline, fails to reach desirable smoke pumping effect.
The purpose of this utility model is to provide the external vortex injection type of a kind of improved blower fan smoke exhaust ventilator for the shortcoming that overcomes above-mentioned prior art, the oil smoke of the generation of culinary art is discharged to the smokejack outlet with rotation shape air-flow, reach desirable smoke pumping effect, and easy to clean.
The purpose of this utility model can realize by following technical measures: this smoke exhaust ventilator has oil smoke cover, blower fan, smokejack, be provided with vortex generator, vortex generator connects smokejack, form an oil smoke gas channel, blower fan is placed on outside the discharge flue, blower fan connects the blast pipe of vortex generator, its cylindrical shell of the oblique cut-grafting of the blast pipe of vortex generator, and it is angled with its tubular axis, the air-flow that blower fan is blown into forms vortex in vortex generator, and flows to the exhaust outlet direction, forms negative pressure on oil smoke cover, suck the oil smoke gas that the kitchen range top produces, discharge to exhaust outlet through the oil smoke gas channel together with swirling eddy.
Structure of the present utility model and embodiment are provided by the following drawings:
Fig. 1 is concrete structure figure of the present utility model.
Fig. 2 is the structure chart of vortex generator.
The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, this smoke exhaust ventilator has oil smoke cover [1], be connected with vortex generator [2] on the oil smoke cover [1], its structure is seen Fig. 2, vortex generator [2] connects smokejack [3] and forms an oil smoke gas channel, blower fan [4] is installed in outside the oil smoke gas channel, blower fan [4] connects the vortex generator blast pipe, its cylindrical shell of the oblique cut-grafting of the blast pipe of vortex generator, and it is angled with its tubular axis, preferably 30～80 ° of this angles, the air-flow that blower fan is blown into forms vortex in vortex generator, rotate into smokejack around the generator axis, and the negative pressure that vortex causes sucks the oil smoke gas that the kitchen range top produces at the other end of vortex generator by oil smoke cover, make it to discharge to the smokejack outlet, reach desirable smoke pumping effect with rotation shape air-flow.In the application, vortex generator can be in any position of oil smoke gas channel.
Of the present utility model simple in structure, reasonable in design, blower fan is placed on the oil smoke flow channel, has exempted oil in the oil smoke gas and has sticked to problem on the draught fan impeller, and the oil smoke road does not have other pipeline and stretches into, cleaning easily produces swirling eddy by vortex generator, makes that oil droplet separates good in the oil smoke gas, the oil smoke gas of discharging is cleaner, reaching desirable oil pumping smoke discharging effect, is a kind of domestic hygiene equipment of practicality, is worthy of popularization.
Claims (2)
1. the external vortex injection type of blower fan smoke exhaust ventilator, oil smoke cover [1], smokejack [3], blower fan [4] are arranged, it is characterized in that being provided with vortex generator [2], vortex generator [2] connects smokejack [3], blower fan [4] is placed on outside the oil smoke gas channel, and blower fan [4] connects the blast pipe of vortex generator [2].
2. smoke exhaust ventilator according to claim 1 is characterized in that the blast pipe of vortex generator and its axis are angled, and this angle is preferably 30～80 °.
