Description
Technical field
The utility model is related to a kind of range hood, especially a kind of top-sucking kitchen ventilator.
Background technology
At present existing top-sucking kitchen ventilator (be arranged on directly over kitchen range, thin type, deep type or tower range hood,
Include side inhale and lower-discharging type) mostly structure type be：Top is set on exhaust fume collecting hood formation concave cavity (smoke collecting chamber), exhaust fume collecting hood
It is provided with air inlet and screen pack.The oil smoke produced in cooking process is collected in smoke collecting chamber, and by connecting with smoke collecting chamber
Logical air channel discharge is outdoor.
A kind of top-sucking kitchen ventilator as disclosed in the Chinese patent application of Application No. 201410315985.7, including collection
Petticoat pipe and the air inlet for being arranged on exhaust fume collecting hood bottom surface, oil collection plate are fixed on the underface of air inlet, are constituted with air inlet bottom surface
The passage of four side air intakes, kuppe is located at the lower surface of oil collection plate, and due to being four side air intakes, smoking efficiency is higher, and water conservancy diversion
Cover can carry out the water conservancy diversion of four direction to oil smoke, at utmost strengthen the fume-exhausting ability of lampblack absorber.
Above-mentioned this range hood, the oil smoke produced by cooking stove below, will by kuppe during ascension
Oil smoke is imported into air inlet, although this range hood can be by the setting of oil collection plate and kuppe so that by oil smoke as far as possible
Suction, but if the oil smoke amount produced is larger or when having external air flow disturbance, oil smoke is easy to from exhaust fume collecting hood both sides
Position is escaped, and thus can not only reduce the smoking efficiency of range hood, and if the phenomenon of fumes escaping is produced, easily to kitchen
The environment in room is impacted, and can also influence the health of user.
Commonly use at present and constitute the mode of air curtain to prevent fumes escaping, the China of such as Application No. 200510106682.5 is specially
Sharp disclosed one kind is by smoke discharging pipe, filter screen and sorbing material, relief valve, parabolic type outer barrel, hyperbolic-type horn mouth, blower fan
Exhaust duct, centrifugal fan, circulating tanks, oil smoke entrance, section oil groove, air curtain ajutage, air inlet, backflow sleeve pipe, row
Smoke pipeline outlet, bottom plate composition.
This traditional range hood air curtain technology, is to be isolated using the blower fan of Whirl entraining soot device with oil smoke, one
Aspect blown and to form air curtain trapping, heat-insulated, and circulating tanks is arrived on the other hand air-supply, and making air-flow, rotation forms low pressure core volume suction at a high speed
Oil smoke.The shortcoming of the technology is air curtain while oil smoke is isolated, and hinders gas to range hood internal flow so that escape
Oil smoke to periphery is difficult to catch, so as to escape；In addition, the circulating path of the air curtain includes：1st, centrifugal blower --- V-shaped groove ---
Smokejack outlet-interior --- centrifugal blower；2nd, centrifugal blower --- air curtain outlet --- oil smoke entrance --- outlet of-smokejack ---
It is indoor --- centrifugal blower；3rd, oil smoke entrance --- outlet of-smokejack ----indoor ----oil smoke entrance, this endless form can be made
Into the pollution of indoor environment.
Also there is a kind of range hood with induction apparatus as shown in Figure 6, the blower fan 1 ' of induction apparatus is from range hood
Outside air intake, certain negative-pressure ward is produced to outside oil smoke and acted on so that the oil smoke in critical condition is due to blower fan
Effect, is escaped into outside range hood action space, with human contact, so as to be absorbed by the body, is produced air pollution, is influenceed body
Health；In addition, from range hood external suction air, easily causing the disturbance of extraneous air, fumes escaping being easily caused on the contrary.
