The invention discloses a top-suction extractor hood with a smoke deflector. The top-suction extractor hood comprises a machine body, an exhaust fume collecting hood and a smoke deflector, wherein the exhaust fume collecting hood is connected to the machine body; a fan is arranged in the machine body; an air inlet is formed on the exhaust fume collecting hood; the smoke deflector is arranged in a manner of directly facing the air inlet of the exhaust fume collecting hood, and a fume passage is formed by a gap between the smoke deflector and the exhaust fume collecting hood; and the lower surface of the smoke deflector is of a wavy structure. According to the top-suction extractor hood disclosed by the invention, by designing the lower surface of the smoke deflector as a wavy structure, roughness of the lower surface of the smoke deflector is enhanced; and a relatively large boundary layer is generated when fume passes through the lower surface of the smoke deflector, so as to enhance a wall attachment effect, thus improving a smoke deflection effect.
Description
Technical field
The present invention relates to a kind of lampblack absorber, especially a kind of top-sucking kitchen ventilator with smoke deflector.
Background technology
The air inlet mode of existing top-sucking kitchen ventilator is typically employed in the exhaust fume collecting hood middle setting air intake of indent at present
The mode of mouth and Inlet Network, a kind of kitchen hood as disclosed in the Chinese patent of Application No. 200520086100.7, including
It is arranged on the exhaust fume collecting hood of bottom and designs in the air channel on exhaust fume collecting hood top, is provided with the middle part of exhaust fume collecting hood and is connected with air channel bottom
Air inlet ring, fan is provided with air channel, air inlet ring bottom is provided with oil cleaner screen, and the bottom of oil cleaner screen is provided with lubricating cup.It is this
The negative pressuren zone of lampblack absorber is concentrated mainly near Inlet Network, that is to say, that high negative pressure area is concentrated mainly on centre, this air draught side
It is unfavorable that formula is used to the user using eyes stove or multi-hole kitchen range, and oil smoke is easily excessive from the cigarette machine left and right sides and front side.
For the problem that above-mentioned traditional top suction type cigarette machine negative pressure is concentrated, Chinese Patent Application No. 200910096759.3 is announced
A kind of top-sucking kitchen ventilator with smoke deflector, in the middle of its exhaust fume collecting hood, air inlet has been provided below one piece of smoke deflector, this leads cigarette
Plate covers the air inlet of whole exhaust fume collecting hood and leave a certain distance with exhaust fume collecting hood top surface and forms air intake passage, the smoke deflector one
Aspect extends air inlet negative pressure toward the left and right sides and front side, solves the problems, such as that traditional top-sucking kitchen ventilator negative pressure is concentrated, separately
On the one hand the smoke deflector plays certain cigarette of leading and acts on, and oil smoke produces wall attachment effect when smoke deflector, can be oil smoke to the left
Right both sides and front side guiding.But as the smoke deflector is smooth plates, the wall attachment effect DeGrain of generation leads cigarette effect not
It is good.
In order to solve the problems, such as that above-mentioned smoke deflector leads cigarette effect on driving birds is not good, Chinese Patent Application No. 201310639355.0 is proposed
A kind of smoke deflector with the concave inward structure that centre is high, surrounding is low, when smoke deflector of the oil smoke through the indent, in female parts
Space forms whirlpool, has thickeied the negative surface thickness on smoke deflector surface to a certain extent, so as to enhance the effect of wall attachment effect,
Achieve certain effect.
The content of the invention
The purpose of the present invention be overcome the shortcomings of it is at least one described in above-mentioned prior art, there is provided it is a kind of with smoke deflector

Low dip is arranged afterwards, and the lower surface of smoke deflector is provided with a plurality of groove being distributed in left-right direction.
Further, in order that the oil droplet that smoke deflector surface is formed smoothly flows into lubricating cup, above-mentioned groove extends to smoke deflector
Front rear lateral edge.
In order to further enhance wall attachment effect, the depth of above-mentioned groove diminishes from front to back.
The surrounding edge of above-mentioned smoke deflector is provided with flange upwards, and the upper surface of smoke deflector in the position of every groove of correspondence
Put to form projection, adjacent two of the upper surface of smoke deflector it is raised between form oil duct, the rear end of oil duct offers oil leaking hole.This
In scheme, on the one hand do not affect oil smoke fluid oil smoke passage to be flowed to along smoke deflector lower surface, on the other hand ensure smoke deflector upper table
The oil droplet that face is formed flows into lubricating cup from the oil leaking hole of smoke deflector rear lateral edge.
Preferably, the shape of cross section of above-mentioned groove is arc, rectangle, triangle or trapezoidal.
Preferably, the depth H of above-mentioned groove is 0.5mm to 10mm.
Another program, is provided with lubricating cup on rear side of above-mentioned smoke deflector, before smoke deflector, after height, low dip is arranged, the following table of smoke deflector
The middle part in face be plane, the arcuate groove that is respectively provided on two sides with of the lower surface of smoke deflector in corresponding flat, and the depth of arcuate groove from
Diminish after forward direction, oil smoke fluid flows through the boundary layer thickness increase formed during arcuate groove.
In order to attractive in appearance, the plane in the middle part of above-mentioned smoke deflector is in " eight " font with the intersection of the arcuate groove of its both sides.
The surrounding edge of above-mentioned smoke deflector is provided with flange upwards, and the upper surface of smoke deflector is in the position shape for corresponding to arcuate groove
Into projection, smoke deflector rear lateral edge offers oil leaking hole.In this programme, on the one hand oil smoke fluid is not affected along smoke deflector lower surface
Oil smoke passage is flowed to, on the other hand ensures that the oil droplet that smoke deflector upper surface is formed flows into oil from the oil leaking hole of smoke deflector rear lateral edge
Cup.
Preferably, depth h of above-mentioned arcuate groove is 0.5mm to 10mm.
The present invention increases the roughness of smoke deflector lower surface as the lower surface of smoke deflector is arranged to wavy, when
Oil smoke will produce larger boundary-layer when the lower surface of the smoke deflector, enhance wall attachment effect, lead cigarette so as to enhance
Effect, the present invention are not only simple in structure, as a plurality of groove is distributed and extends to the front rear lateral edge of smoke deflector in left-right direction,
Equivalent to defining a plurality of smooth smooth oil circuit from front to back so that drip is convenient and effect is good.
