Abstract
The utility model relates to a household split type range hood which is composed of an outdoor blower, a fume exhausting flexible pipe, a fume collecting hood and an additional negative pressure chamber, wherein he negative pressure chamber is communicated with the fume collecting hood by an air entry, and the outdoor blower is communicated with the negative pressure chamber by the fume exhausting flexible pipe. The utility model is characterized in that geometrical planes of the end surfaces of impellers of the two lonely blowers arranged in the outdoor blower are crossed to form a V shape. Due to the adoption of the structure, the flow passage loss of an intake manifold of the blower is reduced, and the aerodynamic efficiency of the blower is enhanced.
Description
The utility model relates to a kind of household smoke exhaust ventilator.
Present known household smoke exhaust ventilator and technical scheme thereof, one class is indoor for blower fan is placed, combine as a whole with exhaust fume collecting hood, blower fan is discharged outdoor through the smoke evacuation flexible pipe soot gas that sucks, its shortcoming is the noise intensity height, be difficult to overcome raising blower fan exhaust air rate and then certainly will strengthen this contradiction of noise intensity of complete machine, thereby limited the further raising of such household smoke exhaust ventilator exhaust air rate; Another kind of technical scheme is: blower fan is placed outdoor, make the blower fan that constitutes household cooker hood main noise source away from exhaust fume collecting hood, avoided above-mentioned contradiction, but when people propose the low noise requirement to household smoke exhaust ventilator, requirement to exhaust air rate also improves day by day, the verandah of the outdoor fan of the household smoke exhaust ventilator of employing split scheme is because must consider easy for installation, the attractive in appearance grade needs, so can not be too big, if adopt a blower fan because of the volume of pursuing outdoor fan is small and exquisite, improve exhaust air rate by the approach that increases power, then very uneconomical.If the exhaust air rate of the blower fan of certain model is increased to original two times through above-mentioned approach, the power of so required blower motor will be far above two times of original motor power; If improve the exhaust air rate of outdoor fan and adopt two blower fans, because of taking the out-to-out of outdoor fan integral body into account, two impellers are arranged in juxtaposition, the geometrical plane of the end of impeller is parallel to each other on two, can cause two distances between fan air inlet narrow again, each fan air inlet air intake duct is the geometrical axis near vertical of inlet manifold and draught fan impeller, and the runner loss in each blower fan inlet manifold is increased, influenced the intake efficiency of blower fan, the efficient of whole outdoor fan is reduced.
The purpose of this utility model is: at the shortcoming of existing household smoke exhaust ventilator and technical scheme thereof, design a kind of novel household smoke exhaust ventilator.
The purpose of this utility model is achieved in that a kind of family expenses separating kitchen ventilator, exhaust fume collecting hood is provided with negative pressure chamber, exhaust fume collecting hood communicates with air entry with negative pressure chamber, outdoor fan communicates with negative pressure chamber on the exhaust fume collecting hood with the smoke evacuation flexible pipe, to outdoor pump drainage gas, its characteristic is: outdoor fan is made up of two independent blower fans, and the geometrical plane of the impeller end of two blower fans is not parallel to each other and does not overlap.
Advantage of the present utility model is: owing to adopt two independent blower fans in the outdoor fan, therefore improved exhaust air rate, simultaneously, because two V-shaped layouts of interior machine, increased the angle between the end face geometrical plane of two impellers, the distance between two fan air inlets is increased, make of the corner minimizing of the inlet manifold of single blower fan to fan air inlet, reduced airflow path loss in the inlet manifold, improved the intake efficiency of each blower fan, and then improved the whole efficiency of outdoor fan.
Fig. 1 is a general illustration of the present utility model.
Fig. 2 is the embodiment schematic diagram of outdoor fan.
Fig. 3 is the embodiment schematic diagram of the exhaust fume collecting hood air entry exhaust fume collecting hood that gos deep into the negative pressure chamber inner space.
Fig. 4 is the embodiment schematic diagram that is provided with the exhaust fume collecting hood of guiding gutter.
Fig. 5 is the embodiment schematic diagram that is provided with the exhaust fume collecting hood of rectification barrier.
Below in conjunction with accompanying drawing the utility model is further described.
As seen from Figure 1, the utility model is by outdoor fan (1), smoke evacuation flexible pipe (6) and is located at negative pressure chamber (7) on the exhaust fume collecting hood (8) and is connected in series successively and forms.
As seen Fig. 2 has two independently centrifugal fans (2) in the outdoor fan (1), the centrifugal fan of two platform independent (2) is " V " type and arranges.The end face geometrical plane of two impellers (3) in the centrifugal blower intersects and also to be " V " type, and motor (4) drives impeller (3) is to the air start, and soot gas is through smoke evacuation flexible pipe (6), be inhaled into blower fan and discharge outdoor through blower fan inlet manifold (5).
Fig. 3 is the embodiment schematic diagram that the air entry of exhaust fume collecting hood (8) gos deep into negative pressure chamber (7), when the air in the negative pressure chamber (7) by outdoor fan (1) when oil drain hose (6) is extracted out, formed the negative pressure with respect to ambient atmosphere pressure in the space of negative pressure chamber (7), soot gas is pressed into negative pressure chamber (7) through exhaust fume collecting hood (8) together with air and is drawn out of outdoor then.
Fig. 4 is the exhaust fume collecting hood embodiment schematic diagram that is provided with guiding gutter (9) in the negative pressure chamber (7).As seen from the figure, guiding gutter (9) is across the air entry of exhaust fume collecting hood (8), because the guide functions of guiding gutter (9) can make in the negative pressure chamber (7) to be easier to be drawn out of away from smoke evacuation flexible pipe (6) one side air.
Fig. 5 is the exhaust fume collecting hood embodiment schematic diagram that is provided with the rectification barrier.As seen from the figure, rectification barrier (10) is " ", and air flows into negative pressure chamber (7) from the two sides of honeycomb screen (10), can improve the peripheral inspiratory effects of exhaust fume collecting hood (8).
By Fig. 3, Fig. 4, Fig. 5 as seen, the side of negative pressure chamber (7) is provided with the interface cover plate (11) of smoke evacuation flexible pipe (6), have the spare interface of smoke evacuation flexible pipe (6) under the cover plate (11), during installation, visual concrete condition is selected the different UNICOMs position of smoke evacuation flexible pipe (6) and negative pressure chamber (7).
Claims (4)
1, a kind of family expenses separating kitchen ventilator, exhaust fume collecting hood is provided with negative pressure chamber, exhaust fume collecting hood communicates with air entry with negative pressure chamber, by outdoor fan, smoke evacuation flexible pipe, the negative pressure chamber of exhaust fume collecting hood connects composition successively, and the geometrical plane of impeller end that it is characterized in that forming two independent blower fans of outdoor fan is not parallel to each other and does not overlap.
2, family expenses separating kitchen ventilator according to claim 1, it is characterized in that: the air entry of exhaust fume collecting hood gos deep in the negative pressure chamber space.
