Abstract
The utility model discloses a Bernoulli blowing and exhausting type range hood and relates to a range hood for a kitchen. The range hood comprises a range hood shell [3], wherein a bottom plate of the shell is provide with an oil smoke suction hole [4]; the left end of the bottom plate of the shell is provided with a guide plate [5]; the outer side of a right end frame of the shell is provided with a cross flow fan [1]; a power switch [2] is arranged on the left side of the cross flow fan; and the left end of an upper cover of the shell is provided with an upward oil smoke extraction duct joint [6]. The Bernoulli blowing and exhausting type range hood is design to overcome the defect that the universal suction and exhaust type range hood fan is attached with oil dirt. The fan and a motor are arranged outside the range hood shell, and fresh air is extracted to blow the high-speed airflow to an oil smoke cavity along the horizontal direction. According to the Bernoulli principle, the high-speed airflow forms a negative pressure area above the oil smoke suction hole. The oil smoke is sucked into the oil smoke cavity through the suction function generated in the negative pressure area, and the oil smoke is immediately blown into an oil smoke discharge pipe by the high-speed airflow and is discharged out of the room. The fan is completely not in contact with the oil smoke, and no oil dirt is attached to the fan.
Description
Technical field the utility model relates to a kind of novel kitchen ventilator of kitchen, be one be mainly reduce to pollute, the new technical scheme of the kitchen fume machine of protection environment, the convenient use and design.
The present general lampblack absorber of background technology all is " suction-discharge type ", and promptly the oil smoke in kitchen range top district directly passes fan, makes fan attach a large amount of greases.Grease not only influences the efficient and the energy consumption of blower fan, cleans grease and also will use a large amount of chemical solvents and strong detergent, thereby cause serious environmental to pollute.
Summary of the invention the utility model Bernoulli Jacob blow type lampblack absorber has a lampblack absorber shell [3], shell bottom plate has an oil suction cigarette hole [4], the shell bottom plate left end is equipped with deflector [5], crossflow fan [1] is equipped with in the right-hand member frame outside of shell, its power switch [2] is contained in the left side of crossflow fan, and the left end of outer casing upper cover is equipped with mist extractor interface tube [6] upwards.
Design object of the present utility model is to overcome the shortcoming that present general " suction-discharge type " lampblack absorber fan attaches a large amount of greases.
The purpose of this utility model is achieved in that the outside that fan and motor is contained in the lampblack absorber shell, extract fresh air from the side along continuous straight runs be blown into high velocity air to the oil smoke chamber.According to bernoulli principle, high velocity air can form negative pressuren zone above oil suction cigarette hole.The suction effect that negative pressuren zone produces sucks the oil smoke chamber to oil smoke, is blown into the oil extraction smoke pipe by high velocity air immediately, discharges outdoor.Fan does not contact with oil smoke fully with motor, and fan and motor can not attach grease, can be in order to avoid clean.
Advantage of the present utility model mainly contains three:
1, Bernoulli Jacob's blow type lampblack absorber has thoroughly been got rid of " suction-discharge type " design of current lampblack absorber now, has designed brand-new " blow type " lampblack absorber according to bernoulli principle.
2, Bernoulli Jacob's blow type lampblack absorber is installed in the outside of lampblack absorber shell to fan and motor, extracts fresh air and is blown into the oil smoke chamber.Fan does not contact with oil smoke fully with motor, can not attach grease, does not therefore need to clean.
3, Bernoulli Jacob's blow type lampblack absorber adopts crossflow fan, and volume is little, and air quantity is big, and air-flow is steady, and noise is little, and energy consumption is low.(energy consumption of at present general " suction-discharge type " lampblack absorber is generally 120W to 250W, and energy consumption to be the air quantity of the crossflow fan of 22W can reach 4.5 ± 0.5m3/min, can satisfy the needs of Bernoulli Jacob's blow type lampblack absorber fully.)
Description of drawings concrete structure of the present utility model is provided by following example and accompanying drawing thereof.
Fig. 1 is the structure chart according to the Bernoulli Jacob's blow type lampblack absorber that the utility model proposes.Fig. 2 is the outside drawing of Bernoulli Jacob's blow type oil smoke frame on the lampblack absorber bearing.
Describe in detail according to details and the working condition that the utility model proposes below in conjunction with Figure of description.
Specific embodiment Bernoulli Jacob's blow type lampblack absorber relates to a kind of oil smoke machine for kitchen use, this lampblack absorber has a lampblack absorber shell (3), shell bottom plate has an oil suction cigarette hole (4), the shell bottom plate left end is equipped with deflector (5), crossflow fan (1) is equipped with in the right-hand member frame outside of shell, blower fan links to each other with adaptive power supply, and its power switch (2) is contained in the left side of crossflow fan, and the left end of outer casing upper cover is equipped with mist extractor interface tube (6) upwards.
Connect power switch (2), crossflow fan (1) starts.The high velocity air that crossflow fan produces along continuous straight runs from right to left is blown into the oil smoke chamber.According to bernoulli principle, high velocity air produces negative pressure in the oil smoke chamber, and the suction effect of negative pressure sucks the oil smoke chamber to the oil smoke in kitchen range district by oil suction cigarette hole (4).Oil smoke is blowed to deflector (5) by high velocity air immediately, and fairshaped deflector is discharged cooking smoke guiding mist extractor interface tube (6) outdoor along the oil extraction smoke pipe.
Lampblack absorber shown in Figure 2 (7) is contained on the lampblack absorber bearing (8), and its lampblack absorber bearing top surrounds with glass, and the bottom surrounds with aluminium sheet.This bearing can separate the fresh air of the oil smoke in kitchen range district and outside, thereby the extraction of assurance crossflow fan is fresh air.The lampblack absorber bearing is the commodity that sell in market, is not that I design.Its current size is long 80cm, wide 45cm, high 95cm.
