The range hood comprises a fan outer hood and an exhaust fume collecting hood, wherein a primary fan and a secondary fan which are connected with each other in series are arranged in the fan outer hood, and an air outlet of the primary fan is communicated with an air inlet of the secondary fan via fluid. The range hood is characterized in that the primary fan and the secondary fan are respectively arranged in parallel vertically and are staggered up and down and forward and backward and do not have overlaps on vertical and horizontal projections. Compared with the prior art, the range hood has the advantages that the primary fan and the secondary fan which are arranged in the fan outer hood are respectively arranged in parallel vertically and are staggered up and down and forward and backward and do not have overlaps on vertical and horizontal projections, so that the installation positions of the primary and secondary fans are very suitable for fan outer hoods with relatively large volumes, especially relatively high and deep fan outer hoods.
Description
Technical field
The utility model relates to range hood, especially relates to the two fan type range hoods of a kind of series connection.
Background technology
The air draft flow of range hood under use state 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 need to be discharged 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 have 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 blast of blower fan system measures positive role to the discharge air flow of range hood, and the existence of back pressure measures negative consequence to the discharge air flow of range hood.
The harmful effect bringing in order to overcome as far as possible back pressure, at present, people have designed the range hood of two fans in series, the range hood of two like this fans in series increases the blast of blower fan system by coupling primary and secondary two-stage blower fan, make blower fan system under use state, even if exist larger back pressure also can obtain larger air draft flow, and the rotating speed of primary and secondary two-stage blower fan is without too high, noise is less, can meet the requirement of the efficient quiet suction of lampblack absorber.But, because existing main blower fan and secondary blower fan are generally oblique parallel setting in blower hood, for two fans in series range hoods of blower hood small volume, primary and secondary two-stage blower fan adopts oblique parallel setting often can save installing space, but, for the larger range hood of blower hood volume, primary and secondary two-stage blower fan should have other different installation sites.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, provides a kind of primary and secondary two-stage blower fan to be applicable to being arranged on the two fan type range hoods of series connection in the blower hood that volume is larger.
The utility model solves the problems of the technologies described above adopted technical scheme: the two fan type range hoods of this series connection, comprise blower hood and exhaust fume collecting hood, in described blower hood, be provided with main blower fan and the secondary blower fan of mutual series connection, the air outlet of described main blower fan is communicated with the air inlet phase fluid of secondary blower fan, it is characterized in that: described main blower fan and secondary blower fan vertically be arranged in parallel respectively in the mode upper and lower, front and back are staggered, 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, on described air-out oralia, has the air vent communicating 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, unique air outlet that the air outlet of described secondary blower fan is this upper chamber.
Further preferably, between described lower chambers and upper chamber, mutually seal isolation by dividing plate, on described dividing plate, have the air vent communicating with the air outlet of main blower fan, be provided with air-out oralia at the top of upper chamber, on described air-out oralia, have the air vent communicating with the air outlet of secondary blower fan.Like this, the oil smoke flowing out from the air outlet of main blower fan enters upper chamber by the air vent of dividing plate, and the oil smoke flowing 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 utility model has the advantage of: the main blower fan and the secondary blower fan that are arranged in blower hood due to the two fan type range hoods of this series connection vertically be arranged in parallel respectively in the mode upper and lower, front and back are staggered, and primary and secondary two-stage blower fan is equal zero lap part in vertical projection and floor projection, thereby the installation site of this primary and secondary two-stage blower fan is very suitable for the blower hood that volume is larger, the particularly highly higher and darker blower hood of the degree of depth.
