The invention discloses a kind of series connection two fans type range hoods, including blower hood and exhaust fume collecting hood, the main blower and secondary fan being serially connected, the air outlet of the main blower and the air inlet configured in fluid communication of secondary fan are equipped in the blower hood, it is characterised in that：The main blower and secondary fan distinguished in a manner of upper layer and lower layer it is vertically arranged, and the air inlet of the main blower towards with the air inlet of secondary fan towards vertical.Compared with the prior art, the advantages of the present invention are as follows：The main blower and secondary fan being arranged in blower hood due to the series connection two fans type range hood are distinguished vertically arranged in a manner of upper layer and lower layer, and the air inlet direction of main blower is vertical with the air inlet of secondary fan direction, thus more novel and primary and secondary two-stage blower the installation site of installation site of the primary and secondary two-stage blower in blower hood can be installed more flexible there are many selection.
Description
Technical field
The present invention relates to a kind of range hoods, more particularly, to a kind of series connection two fans type range hood.
Background technique
The air draft flow of range hood in a state of use depends primarily on the wind pressure of cooking-fume exhauster blower system, and wind pressure is got over
Greatly, air draft flow is also bigger.When in use, oil smoke is needed through smoke exhaust pipe, check (non-return) valve and smoke evacuation the range hood of normal domestic use
Oil smoke is discharged the resistance devices such as channel, the presence of these resistance devices, so that oil smoke exists centainly at oil smoke outlet
The presence of back pressure, back pressure can largely effect on the air draft flow of kitchen ventilator.Air draft flow of the wind pressure of blower fan system to range hood
It has a positive effect, the presence of back pressure then plays negative consequence to the air draft flow of range hood.
In order to overcome back pressure bring adverse effect as far as possible, currently, people have been designed that the concatenated suction of two fans
Kitchen ventilator, this concatenated range hood of two fans are increased the wind pressure of blower fan system by matching primary and secondary two-stage blower, make wind
Machine system in a state of use, can obtain biggish air draft flow there are biggish back pressure, and primary and secondary two-stage blower
For revolving speed without too high, noise is smaller, is able to satisfy the requirement of the efficiently quiet suction of kitchen ventilator.However, due to existing main blower and time
Grade blower is arranged in parallel in blower hood, and main blower is consistent with the air inlet of secondary fan direction, thus this master,
The installation site of secondary two-stage blower is more universal, can be further improved.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to above-mentioned state of the art, provide in a kind of blower hood
The more novel series connection two fans type range hood of the installation site of primary and secondary two-stage blower.
The present invention solves technical solution used by above-mentioned technical problem：The series connection two fans type range hood, including
Blower hood and exhaust fume collecting hood, the blower hood is interior to be equipped with the main blower and secondary fan being serially connected, the main blower
Air outlet and secondary fan air inlet configured in fluid communication, it is characterised in that：It is more than the main blower and secondary fan
Lower two layers of mode distinguish it is vertically arranged, and the air inlet of the main blower towards with the air inlet of secondary fan towards vertical.
Preferably, the blower hood is divided into upper layer and lower layer chamber, and the main blower is arranged in bottom chamber, institute
The secondary fan stated is arranged in upper chamber, and the air outlet of the main blower is unique air inlet of the upper chamber, described
The air outlet of secondary fan is unique air outlet of the upper chamber.
Further preferably, it is mutually closed and is isolated by partition between the lower chambers and upper chamber, on the partition
It is provided with the ventilation hole communicated with the air outlet of main blower, outlet air oralia is equipped at the top of upper chamber, in the outlet air oralia
On be provided with the ventilation hole communicated with the air outlet of the secondary fan.In this way, the oil smoke flowed out from the air outlet of main blower is logical
The ventilation hole for crossing partition enters upper chamber, and the oil smoke flowed out from the air outlet of secondary fan is entered by the ventilation hole of outlet air oralia
The discharge pipe of range hood.
As the preferred of any of the above-described scheme, the air outlet of the main blower and the air inlet of secondary fan pass through wind-guiding
Connecting tube is connected.After connecting by wind-guiding connecting tube, the flow field of blower fan system can be made more preferable, oil smoke will not be in blower hood
Residual.
It can be there are many positional relationship between air inlet and the range hood front of main blower, it is preferable that the main
The air inlet direction of blower and range hood front are parallel or perpendicular.
Compared with the prior art, the advantages of the present invention are as follows：Since the series connection two fans type range hood is arranged in blower
Main blower and secondary fan in outer cover distinguished in a manner of upper layer and lower layer it is vertically arranged, and main blower air inlet towards with
The air inlet of secondary fan towards vertical, thus installation site of the primary and secondary two-stage blower in blower hood it is more novel and
The installation site of primary and secondary two-stage blower can be installed more flexible there are many selection.
