Description
Technical field
The utility model relates to a kind of 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 this pair of 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.Yet, 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, thereby the installation site of this primary and secondary two-stage blower fan is comparatively general, can be further improved.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, and the comparatively novel two fan type range hoods of series connection in installation site of the primary and secondary two-stage blower fan in a kind of blower hood are provided.
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 be with upper and lower two-layer mode vertical setting respectively, and the air inlet of described main blower fan towards the air inlet with secondary blower fan towards vertical.
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, unique air outlet that the air outlet of described secondary blower fan is described upper chamber.
Further preferably, between described lower chambers and upper chamber, by dividing plate, mutually seal isolation, on described dividing plate, have the air vent communicating with the air outlet of main blower fan, at the top of upper chamber, be provided with air-out oralia, on described air-out oralia, have the air vent communicating with the air outlet of described 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.
As above-mentioned arbitrary scheme preferably, the air outlet of described main blower fan is connected by wind-guiding tube connector with the air inlet of secondary blower fan.After connecting by wind-guiding tube connector, can make the flow field of blower fan system better, oil smoke can be not residual in blower hood.
Between the air inlet of main blower fan and range hood front, can have multiple position relationship, preferably, the air inlet of described main blower fan is towards paralleling with range hood front or perpendicular.
Compared with prior art, the utility model has the advantage of: the main blower fan and the secondary blower fan that due to the two fan type range hoods of this series connection, are arranged in blower hood vertically arrange respectively in upper and lower two-layer mode, and the air inlet of main blower fan towards the air inlet with secondary blower fan towards vertical, thereby can there be multiple choices installation site comparatively novel and primary and secondary two-stage blower fan, the installation site of primary and secondary two-stage blower fan in blower hood, install comparatively flexible.
