Abstract
A series connection fan type extractor hood comprises a fan housing and an exhaust fume collecting hood, wherein a primary fan and a secondary fan which are mutually connected in series are arranged in the fan housing; and an air outlet of the primary fan is in fluid communication with an air inlet of the secondary fan. The series connection fan type extractor hood is characterized in that the primary fan and the secondary fan are arranged in parallel in the oblique direction; and the center of the primary fan and the center of the secondary fan are mutually staggered in the vertical direction. Compared with the prior art, the series connection fan type extractor hood has the advantages that the primary fan and the secondary fan of the series connection fan type extractor hood are arranged in the fan housing in parallel in the oblique direction, so that the mounting space of the fans can be saved; in addition, since the center of the primary fan and the center of the secondary fan are mutually staggered in the vertical direction, different mounting positions of the primary fan and the secondary fan can be formed in the fan housing, and the fan housing can correspondingly have different shapes, and the shapes of the extractor hood can be enriched.
Description
Technical field
The present invention relates to a kind of range hood, especially relate to a kind of series connection fan type range hood.
Background technology
Range hood air draft flow in a state of use depends primarily on the blast of cooking-fume exhauster blower system, and blast is larger, and air draft flow is also larger.The range hood of normal domestic use in use, oil smoke needs to be discharged by oil smoke by drag devices such as smoke exhaust pipe, check (non-return) valve and discharge flues, the existence of these drag devices, makes oil smoke there is certain back pressure at oil smoke outlet place, and the existence of back pressure can affect the air draft flow of lampblack absorber greatly.The discharge air flow of blast to range hood of blower fan system measures positive role, and the existence of back pressure then measures negative consequence to the discharge air flow of range hood.
In order to overcome the harmful effect that back pressure is brought as far as possible, at present, people have devised the range hood of two fans series connection, the range hood of this two fans series connection increases the blast of blower fan system by coupling primary and secondary two-stage blower fan, make blower fan system in a state of use, even if there is larger back pressure also can obtain larger air draft flow, and the rotating speed of primary and secondary two-stage blower fan is without the need to too high, noise is less, can meet the requirement of the efficient quiet suction of lampblack absorber.The primary and secondary two-stage blower fan of existing series connection two fans type range hood is generally and vertically arranges up and down, and the center in the vertical direction of primary and secondary two-stage blower fan does not stagger mutually, the defect that this series connection two fans type range hood exists is: the installation site due to primary and secondary two-stage blower fan is consistency from top to bottom distribution, thus its blower hood is king-size outer cover, and then causes the shape of blower hood comparatively single.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned prior art present situation, provides a kind of primary and secondary two-stage blower fan can have the series connection fan type range hood of multiple installation site in blower hood.
The present invention solves the problems of the technologies described above adopted technical scheme: this series connection fan type range hood, comprise blower hood and exhaust fume collecting hood, the main blower fan of series connection mutually and secondary blower fan is provided with in described blower hood, the air outlet of described main blower fan and the air inlet configured in fluid communication of secondary blower fan, it is characterized in that: described main blower fan and secondary blower fan oblique parallel are arranged, and the center of described main blower fan and the center in the vertical direction of secondary blower fan stagger mutually.
Preferably, described main blower fan and the projection in the horizontal plane of secondary blower fan do not have lap.After adopting said structure, secondary blower fan overall can be positioned at the top of main blower fan, also the top of main blower fan can be locally positioned at, also can be disposed adjacent with main blower fan and be positioned at sustained height position, thus make main blower fan and secondary blower fan installation position each other be equipped with multiple choices, and then blower hood is made to have different shapes.
Further preferably, the line between the center of described main blower fan and the center of secondary blower fan is parallel to the front of described blower hood.Adopt after said structure, main blower fan and secondary blower fan installation site are each other able to further restriction, make blower hood size in the longitudinal direction can not be excessive.
Further preferably, the scope of the angle α between the line at the center of described main blower fan and the center of secondary blower fan and vertical curve is: 30 °≤α≤60 °.
Further preferably, angle α=45 ° between the line at the center of described main blower fan and the center of secondary blower fan and vertical curve
The wind energy blown out to make main fan outlet enters the air intake vent of secondary blower fan smoothly, described blower hood is divided into upper and lower two-layer chamber, described main blower fan is arranged on bottom chamber, described secondary blower fan is arranged in upper chamber, and the air outlet of main blower fan is connected by tube connector with the air inlet of secondary blower fan.
Further preferably, angle α=90 ° between the line at the center of described main blower fan and the center of secondary blower fan and vertical curve.Adopt after said structure, be disposed adjacent about main frame blower fan and secondary blower fan and be positioned on sustained height.
Further preferably, described blower hood has an assembling chamber, and described main blower fan and secondary blower fan are positioned at described assembling chamber, are connected between main blower fan with secondary blower fan by tube connector.
Main blower fan and secondary blower fan can adopt multiple angle of inclination, and preferably, described main blower fan and secondary blower fan are 20 ~ 40 ° relative to the angle of inclination of vertical curve.
Further preferably, described main blower fan and secondary blower fan are 30 ° relative to the angle of inclination of vertical curve.
Compared with prior art, the invention has the advantages that: main blower fan and the secondary blower fan oblique parallel of this series connection fan type range hood are arranged in blower hood, assembling space can be saved, in addition, because the center of main blower fan and the center in the vertical direction of secondary blower fan stagger mutually, thus main blower fan and secondary blower fan can have multiple different installation site in blower hood, and blower hood is corresponding can multiple different shape, thus make the profile more horn of plenty of range hood.
