Description
Technical field
The present invention relates to the range hoods that a kind of smoke deflector and application have the smoke deflector.
Background technique
A kind of Chinese invention " range hood with smoke deflector " (Authorization Notice No. of Patent No. ZL200910096759.3
For CN10514823B), which has body, exhaust fume collecting hood and smoke deflector, and exhaust fume collecting hood is equipped with air inlet, and smoke deflector is (again
Claim smoke deflector) the face air inlet setting and maintain scheduled spacing with exhaust fume collecting hood, thus in both smoke deflector and exhaust fume collecting hood
Between be formed with and hold the oil smoke channel that passes through of oil smoke, the smoke deflector in the patent is fixed setting, the position in oil smoke channel
And size cannot be adjusted, there are following deficiencies:
(1) this top-sucking kitchen ventilator integral installation height determines that the pot of range hood distance generation oil smoke compares
Far, negative pressure loss is bigger；
(2) smoke deflector is located at exhaust fume collecting hood port and design seperated with exhaust fume collecting hood, and range hood is installed after smoke deflector very big
The depth of exhaust fume collecting hood is reduced in degree, often since oil smoke absorption a degree of blasting fume phenomenon occurs not in time.
Summary of the invention
Increase smoke deflector can be passed through the technical problem to be solved by the invention for the present situation of prior art is to provide a kind of
Periphery negative pressure and the smoke deflector for improving oil smoke assimilation effect.

Another technical problem to be solved by this invention is the status for the prior art, provide a kind of application have it is above-mentioned
The range hood of smoke deflector, the range hood improve oil smoke assimilation effect by increasing the periphery negative pressure of smoke deflector.
The technical scheme of the invention to solve the technical problem is: a kind of smoke deflector, including smoke deflector ontology,
It is characterized in that: further including axial flow blower, which is set to the rear side of smoke deflector ontology；It is offered on the smoke deflector ontology
The front end of ventilation opening, the axial flow blower has air inlet corresponding with the ventilation opening, and the rear end of the axial flow blower has
Air outlet.
As an improvement, it is logical to be provided with the first oil smoke that self-ventilation mouth edge gradually extends back on the smoke deflector ontology
Road is provided with the hole for passing through for oil smoke and generating ejector action to oil smoke, the axial flow blower on the side wall in the first oil smoke channel
Set on the rear end in the first oil smoke channel.Using the structure, the oil smoke generation by ventilation opening can be drawn in the larger context
The effect of penetrating accelerates oil smoke sucking, improves oil smoke assimilation effect.
Preferably, the internal diameter in first oil smoke channel is gradually reduced from front to back.The structure actually increases first
The internal surface area in oil smoke channel increases the area for generating the hole of ejector action, further increases oil smoke assimilation effect.
It improves again, is provided with the secondary plate that can cover or open ventilation opening on front side of the smoke deflector ontology, the secondary
Plate will be formed with the second oil smoke channel between the smoke deflector ontology under ventilation opening opening state.The secondary plate is set, it can
Control oil smoke assimilation effect opens the secondary plate when a large amount of oil smoke generate rapidly to a certain extent, on the one hand utilizes axis stream
A large amount of oil smoke are directly pushed into flue by the negative pressure and ejector action that blower generates at ventilation opening, and on the other hand, axial flow blower exists
Also the negative pressure on rear side of smoke deflector ontology can be reduced when operation, and surplus oil smoke is sucked from smoke deflector body edges；When oil smoke generates
When speed is slower, secondary plate is closed, the negative pressure reduced on rear side of smoke deflector ontology is run using axial flow blower and will gradually be generated
Oil smoke absorbs.
It for ease of operation and uses, the smoke deflector further includes the driving machine that the secondary plate can be driven to be moved forward and backward
Structure.
In the above scheme, the driving mechanism includes connecting rod, drive rod and actuator, is opened on the smoke deflector ontology
There is opening corresponding with secondary plate edge, the first end of the connecting rod passes through opening and the edge of secondary plate is rotatablely connected, institute
State drive rod vertical links arrangement and be rotatablely connected with the second end of connecting rod, the drive rod be located at smoke deflector ontology rear side and with
Actuator is connected.
Preferably, the actuator is push-rod electric machine, the push rod of the push-rod electric machine arranged perpendicular to drive rod and with this
Drive rod is connected.
For the ease of connection, the sliding slot along Opening length direction arrangement is provided on the trailing flank of the smoke deflector ontology,
The end of the drive rod can be set in the sliding slot with moving back and forth along the chute.
A kind of application has the range hood of above-mentioned smoke deflector, including main air blower, exhaust fume collecting hood and smoke deflector, the exhaust fume collecting hood tool
There is the first air inlet from bottom to top, it is characterised in that: the smoke deflector ontology is set to below the first air inlet of exhaust fume collecting hood, institute
State the front side that axial flow blower is located at the first air inlet.
In the above scheme, the third oil smoke that gas supply stream passes through is formed between the smoke deflector ontology and the first air inlet
Channel.
Compared with the prior art, the advantages of the present invention are as follows: the present invention offers in smoke deflector main body towards fume-exhausting
The ventilation opening of the air inlet arrangement of machine, and axial flow blower is provided at the ventilation opening, use the suction with smoke deflector of the present invention
When kitchen ventilator, oil smoke rises and close to ventilation opening, and the power that axial flow blower operation generates can will rise to the oil near ventilation opening
Cigarette directly and is rapidly pushed into flue, and a large amount of oil smoke are discharged, meanwhile, axial flow blower can increase smoke deflector when running
Negative pressure on rear side of ontology is conducive to oil smoke sucking flue from the edge of smoke deflector ontology, in addition, axial flow blower also can when running
Certain ejector action is generated at ventilation opening edge, is conducive to the sucking of oil smoke；To improve oil smoke assimilation effect.
