Description
Technical field
The present invention relates to a kind of range hood.
Background technology
For the existing range hood with cowling panel, in the presence of cowling panel, negative pressuren zone is in below smoke collecting chamber
Between concentrate be changed into circumferentially distributed, expand the control range of range hood.When oil smoke amount is larger, oil smoke has below cowling panel
One waiting process, makes oil smoke suction have delay, or even produce race cigarette phenomenon.If can cause to let out if cowling panel slotting in middle
Pressure so that ring negative pressure weakens, and causes smoke absorption effect poor.In addition, having by installing crossflow fan to carry in the prior art
In the range hood of high oil absorption cigarette machine clean absorption rate, such as Application No. 200910144426.3 (Publication No. CN101614415A)
Disclosed in state's application for a patent for invention《Energy-saving, environment-friendly and high-efficiency side-draft range hood》, the lampblack absorber is by smoking blower fan, petticoat pipe and horizontal stroke
Flow fan is constituted, and crossflow fan is arranged on lampblack absorber petticoat pipe edge, and the air inlet of crossflow fan is located above petticoat pipe or side,
The air outlet of crossflow fan is located at below petticoat pipe edge.When the lampblack absorber works, the air curtain air-flow of crossflow fan formation makes petticoat pipe
Oil smoke below interior and petticoat pipe can not be escaped by edge, significantly reduce absorption height of the lampblack absorber to lower section oil smoke, increase
The coverage rate that oil smoke is drawn, greatly improved lampblack absorber clean absorption rate, and reducing centrifugation makes the use power of formula blower fan, while
Oil smoke acc power and noise is set to decline to a great extent, energy-conserving and environment-protective.Although the above-mentioned lampblack absorber for being provided with crossflow fan has above-mentioned excellent
Point, still, the energy-saving, environment-friendly and high-efficiency side-draft range hood are only applicable to not install the occasion of cowling panel in petticoat pipe, if pacifying in petticoat pipe
Equipped with cowling panel, then lampblack absorber clean absorption rate can not only be greatly improved by installing crossflow fan at lampblack absorber petticoat pipe edge, on the contrary can
The negative pressure distribution destroyed below exhaust fume collecting hood, so as to cause smoke absorption effect to decline.In summary, cowling panel is carried for existing
Range hood, need to be further improved its structure.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned state of the art neither to weaken cowling panel there is provided one kind
Circumferential negative pressure can increase the range hood in central negative pressure region again.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：The range hood, include blower hood and
Exhaust fume collecting hood below blower hood, main air blower is provided with the blower hood, formed below whole in the exhaust fume collecting hood
Flow in chamber, rectifying cavity and cowling panel be installed, it is characterised in that：Also include crossflow fan, be provided with the centre of the cowling panel
The front and rear bar shaped air inlet to distribution, the crossflow fan is arranged on bar shaped air inlet, and the bar shaped air inlet constitutes crossing current wind
The air inlet of machine, the air outlet of the crossflow fan is located above the cowling panel.
As a kind of preferred scheme, described main air blower has one and positioned at the surface of the crossflow fan.
Main air blower can have a variety of position relationships with crossflow fan, it is preferable that the axis of the main air blower and the horizontal stroke
The axis of flow fan is located on same upright plane.After said structure, the auxiliary suction of crossflow fan can be effectively improved
The effect of oil smoke.
As another preferred scheme, described main air blower has two and is arranged in parallel, and two main air blowers are located at institute respectively
The left and right sides directly over crossflow fan is stated, also, the axis of two main air blowers and the axis of the crossflow fan are mutual
It is parallel.After said structure, the effect of the auxiliary suction oil smoke of crossflow fan can be effectively improved.
Further preferably, an outlet housing, the air inlet end of two main air blowers are installed on the blower hood
Plane is located on same upright plane where portion, and the air outlet of two main air blowers is connected on the outlet housing.
In order to enter crossflow fan air-flow carry out rectification, the bar shaped air inlet be provided with least two along
The parting bead that the length direction of bar shaped air inlet is set, and width of each parting bead along bar shaped air inlet be spaced point successively
Cloth.
Further preferably, the range hood also includes Smoke Sensor and controller, and the Smoke Sensor is arranged on
On exhaust fume collecting hood, the signal output part of the Smoke Sensor is connected with the signal input part of the controller, and the controller leads to
Cross receive the output signal of Smoke Sensor control crossflow fan turn stop or rotating speed size.So, range hood works
When, the smog size of both sides is detected by Smoke Sensor, when the amount of smoke detected is smaller, middle crossflow fan not work
Make, negative pressure is provided by the main air blower of blower fan system；When the smog detected is larger, middle crossflow fan is opened, auxiliary
Oil smoke is aspirated, and strengthens main air blower air quantity, the purpose of lifting smoke absorption effect is reached.
In order to be able to detect the smog size of cowling panel both sides, described Smoke Sensor has two and installed in the collection cigarette
On cover, also, two Smoke Sensors are located at the left and right sides of the cowling panel respectively.
Compared with prior art, the advantage of the invention is that：The range hood in the middle of cowling panel by opening bar shaped air intake
Mouthful, and install crossflow fan enhancing negative pressure additional in air inlet, so in the case of ensureing that the circumferential negative pressure of cowling panel is unabated, increase
Central negative pressure region is added so that lampblack absorber there can not only be larger Tobacco Control region, and oil smoke can be quickly aspirated again, so as to have
Effect lifting smoke absorption effect.
