Description
Technical field
The present invention relates to a kind of range hoods.
Background technique
A kind of Chinese invention " range hood with smoke deflector " (Authorization Notice No. of Patent No. ZL200910096759.3
For CN101514823B), which has body, exhaust fume collecting hood and smoke deflector, and exhaust fume collecting hood is equipped with air inlet, smoke deflector
(also known as cowling panel) face air inlet is arranged and maintains scheduled spacing with exhaust fume collecting hood, thus in smoke deflector and exhaust fume collecting hood two
It is formed between person and holds the oil smoke channel that oil smoke passes through, the smoke deflector in the patent is fixed setting, the position in oil smoke channel
It sets 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 range hood for improving oil smoke assimilation effect.
The technical scheme of the invention to solve the technical problem is: a kind of range hood, including exhaust fume collecting hood, lead cigarette
Plate and fan shroud, the exhaust fume collecting hood have the first air inlet, and the smoke deflector is set to below the first air inlet, and the blower is provide with
Above the first air inlet, and the inner cavity of the fan shroud constitutes and leads cigarette main channel, it is characterised in that: further includes accessory fan and leads
Cigarette subchannel is provided with close to the first air inlet arrangement on the exhaust fume collecting hood in position corresponding with the edge of the smoke deflector
Second air inlet；The accessory fan is set to above exhaust fume collecting hood and the air inlet of accessory fan is corresponding with the second air inlet, institute
It states and leads cigarette subchannel above exhaust fume collecting hood and lead the flue gas for passing through the second air inlet from bottom to top in cigarette main channel.
In the above scheme, the channel for leading cigarette subchannel and including mounting cup and being connected with the mounting cup, the peace
Dress covers on exhaust fume collecting hood and surrounds accessory fan wherein, and the channel is set to the side of mounting cup, opens on the fan shroud
There is the 4th air inlet being connected with the outlet side in channel.The structure is set, in order to which the flue gas for drawing accessory fan imports
Fan shroud is led in cigarette main channel.
Preferably, after the channel middle is bent to form the front being connected with mounting cup and is connected with fan shroud
Portion, the rear portion in the channel and leads arrangement at an acute angle between cigarette main channel.Preferably, the rear portion in the channel and cigarette main channel is led
Between in 30~55 ° of angles arrangement.Using such structure, oil smoke can be sent directly into blower fan system, prevented due to excessive
Oil smoke is gathered in flue collector, causes oil smoke excessive.
As an improvement, the area of second air inlet is greater than the air-admitting surface of accessory fan, second air inlet
On be provided with secondary strainer, be provided with baffle above the secondary strainer, the air inlet phase with accessory fan be provided on the baffle
Corresponding opening.Collection cigarette cavity is formed between the secondary strainer and baffle.The structure is set, to increase auxiliary air inlet face
Product, further avoids fumes escaping.
It improves again, the secondary strainer has a plurality of spaced apart filter item, and each filter inner hollow is to form energy
The accommodating cavity of active carbon particle is loaded, the end of the accommodating cavity has the port being connected with the collection cigarette cavity.The knot is set
Structure can be removed smoke particle before oil smoke is imported fan shroud, and to avoid the part, oil smoke pollutes blower.
Preferably, the edge of second air inlet is recessed upwards forms mounting groove, the edge shaping of the secondary strainer
It is connected for the frame that can be embedded in the mounting groove, the frame inner hollow and with the port of the filter item, the top of the frame
Arrangement is opened wide to be connected with collection cigarette cavity by portion.
In above-mentioned each preferred embodiment, main strainer, and the top setting of the main strainer are provided on first air inlet
There is the adsorption layer that the main strainer can be covered.The adsorption layer is preferably replaceable spongy layer, active carbon layer etc..The knot is set
Structure can be removed to by a large amount of oil smoke of the first air inlet, prevent oil smoke from polluting to blower, to keep fume-exhausting to begin
There is preferable oil smoke suction function eventually.
Preferably, third air inlet, the collection cigarette are constituted between the lower roof of the exhaust fume collecting hood and the upper roof of smoke deflector
The roof of cover tilts gradually downward from edge to the first air inlet, corresponding, and the smoke deflector is gradually upward from edge to centre
Inclination, so that the bore of the third air inlet be made to be gradually reduced according to flue gas circulating direction from upstream to downstream.The structure can
Wind speed is improved, oil smoke adsorption effect is enhanced.
Further preferably, the accessory fan is centrifugal blower, the axial line of the centrifugal blower and corresponding smoke deflector it
Between arrangement at an acute angle.Using such structure, centrifugal blower can be improved to the pressurization at smoke deflector edge, further increase oil
Cigarette adsorption capacity.
Compared with the prior art, the advantages of the present invention are as follows: the present invention has opened up the side of corresponding smoke deflector on exhaust fume collecting hood
Second air inlet of edge arrangement, and being provided with can make oil smoke pass through the accessory fan that is directly entered after the second air inlet in exhaust fume collecting hood
And cigarette subchannel is led, in use when oil smoke concentration is higher, accessory fan is opened, the stream above smoke deflector can be improved
, the negative pressure on smoke deflector periphery is increased, oil smoke infiltration rate is effectively improved, prevents oil smoke from escaping from smoke deflector periphery, is improved
Oil smoke assimilation effect.
