Abstract
The invention discloses a serial double-fan-type range hood comprising an outer fan cover and a smoke collecting cover, wherein the outer fan cover is internally provided with a primary fan and a secondary fan which are connected in series; and an air outlet of the primary fan is communicated with an air inlet of the secondary fan through a fluid. The serial double-fan-type range hood is characterized in that the primary fan and the secondary fan are respectively and vertically arranged in a way of one at the upper layer and the other one at the lower layer, and the direction of an air inlet of the primary fan is vertical to the direction of the air inlet of the secondary fan. Compared with the prior art, the serial double-fan-type range hood has the advantages that the primary fan and the secondary fan which are arranged in the outer fan cover are respectively and vertically arranged in a way of one at the upper layer and the other one at the lower layer, and the direction of the air inlet of the primary fan is vertical to the direction of the air inlet of the secondary fan, so that the mounting positions of the primary fan and the secondary fan in the outer fan cover are relatively novel; and the primary fan and the secondary fan can be mounted on a plurality of positions so as to be relatively flexible in mounting.
Description
Technical field
The present invention relates to a kind of 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 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.But, due to existing main blower fan and secondary blower fan in blower hood for be arrangeding in parallel, and the air inlet of main blower fan and secondary blower fan is towards consistent, and thus the installation site of this primary and secondary two-stage blower fan is comparatively general, can be further improved.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned prior art present situation, provides the series connection two fans type range hood that the installation site of the primary and secondary two-stage blower fan in a kind of blower hood is comparatively novel.
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: described main blower fan and secondary blower fan are arranged so that upper and lower two-layer mode is vertical respectively, and the air inlet of described main blower fan towards the air inlet with secondary blower fan vertically.
Preferably, 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 described upper chamber, and the air outlet of described secondary blower fan is unique air outlet of described 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 described 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.
Preferred as above-mentioned either a program, the air outlet of described main blower fan is connected by wind-guiding tube connector with the air inlet of secondary blower fan.After being connected by wind-guiding tube connector, the flow field of blower fan system can be made better, and oil smoke can not remain in blower hood.
Can have multiple position relationship between the air inlet of main blower fan and range hood front, preferably, the air inlet of described main blower fan is towards to parallel with range hood front or perpendicular.
Compared with prior art, the invention has the advantages that: be arranged on main blower fan in blower hood due to this series connection two fans type range hood and secondary blower fan is arranged so that upper and lower two-layer mode is vertical respectively, and the air inlet of main blower fan towards the air inlet with secondary blower fan vertically, thus the installation site of primary and secondary two-stage blower fan in blower hood is comparatively novel and can there be multiple choices the installation site of primary and secondary two-stage blower fan, installs comparatively flexible.
