The serial double-fan-type range hood is characterized in that the primary fan and the secondary fan are respectively and vertically arranged in parallel and in a vertically and horizontally staggered way, and the vertical and horizontal projections of the primary fan and the secondary fan have no overlapped parts. Compared with the prior art, the serial double-fan-type range hood has the advantages that the primary fan and the secondary fan are respectively and vertically arranged in parallel and in a vertically and horizontally staggered way, and the vertical and horizontal projections of the primary fan and the secondary fan have no overlapped parts, so that the mounting positions of the primary fan and the secondary fan are very suitable for outer fan covers with relatively large volumes and are particularly suitable for outer fan covers with relatively large heights and depths.
Description
Technical field
The present invention relates to range hood, especially relate to a kind of series connection two fans 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 such 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.But, arrange because existing main blower fan and secondary blower fan are generally oblique parallel in blower hood, for the two fans series connection range hood of blower hood small volume, primary and secondary two-stage blower fan adopts oblique parallel to arrange often can save installing space, but, for the range hood that blower hood volume is larger, primary and secondary two-stage blower fan should have other different installation sites.
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 to be applicable to the series connection two fans type range hood be arranged in the larger blower hood of volume.
The present invention solves the problems of the technologies described above adopted technical scheme: this series connection two fans 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: the mode that described main blower fan and secondary blower fan are staggered with upper and lower, front and back vertically be arranged in parallel respectively, and primary and secondary two-stage blower fan equal zero lap part in vertical projection and floor projection.
As a kind of preferred version of blower hood, described blower hood is an overall chamber, and the air outlet of described main blower fan is connected by wind-guiding tube connector with the air inlet of secondary blower fan.
Further preferably, the top of described blower hood is provided with air-out oralia, and described air-out oralia has the air vent communicated with the air outlet of described secondary blower fan.
As another preferred version of blower hood, 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, the air outlet of described main blower fan is unique air inlet of this upper chamber, and the air outlet of described secondary blower fan is unique air outlet of this upper chamber.
Further preferably, mutually closed by dividing plate between described lower chambers and upper chamber and isolate, described dividing plate has the air vent communicated with the air outlet of main blower fan, be provided with air-out oralia at the top of upper chamber, described air-out oralia has the air vent communicated with the air outlet of secondary blower fan.Like this, the oil smoke flowed out from the air outlet of main blower fan enters upper chamber by the air vent of dividing plate, and the oil smoke flowed out from the air outlet of secondary blower fan enters the discharge pipe of range hood by the air vent of air-out oralia.
Primary and secondary two-stage blower fan can have multiple installation site, and preferably, the air inlet place plane of described main blower fan parallels with the front of range hood.
In order to make assembling firm, in described blower hood, be provided with blower rack, described main blower fan and secondary assembling are on described blower rack.
Compared with prior art, the invention has the advantages that: vertically be arranged in parallel respectively because this series connection two fans type range hood is arranged on the mode that main blower fan in blower hood and secondary blower fan be staggered with upper and lower, front and back, and primary and secondary two-stage blower fan equal zero lap part in vertical projection and floor projection, thus the installation site of this primary and secondary two-stage blower fan is very suitable for the larger blower hood of volume, the blower hood that particularly highly higher the and degree of depth is darker.
Accompanying drawing explanation
