Abstract
The utility model relates to a rectifying noise-reducing near-suction range hood comprising a shell, a user-inclined panel on the shell, a blower component arranged behind the panel in the shell, air inlets arranged on the panel and an air outlet arranged on the shell. The rectifying noise-reducing near-suction range hood is characterized in that an air intake of the blower component is mounted opposite to the panel, and the air inlets are connected with a rectifying passage in the shell and guides indrawn air to the air intake of the blower component. The utility model further reduces the noise of the range hood by mounting the air intake of the blower component opposite to the panel in comparison with the air intake facing the panel, not only can further lower the noise of the whole range hood, but also can relatively and uniformly distribute the intake air of the air inlets so as to improve the smoke suction effect.
Description
Technical field
The utility model relates to a kind of range hood, particularly relates to a kind of side-suction type range hood.
Background technology
The kitchen of Modern Family, fume exhausting fan generally all is housed, range hood relatively early is an overhead guard formula range hood, be that smoke exhaust ventilator is vertically mounted on the upper space that the source takes place oil smoke, its shortcoming be if lampblack absorber from oil smoke generation spacing from too near, then can hinder cooking personnel's operation, and if lampblack absorber is too far away from oil smoke generation source, then can cause diffusion, the smoke pumping of oil smoke unclean, and, after also can being bonded on the filter screen because of greasy dirt, the range hood of overhead guard formula, causes the pollution of dish because of self gravitation drips.Therefore occurred the height of smoking port is suitably reduced, changed over the position near the pot face, air draught face becomes the side air draught type lampblack absorber of skew crossing type with the pot face, be also referred to as the near-absorption type smoke exhaust ventilator.As the disclosed side air inlet smoke exhaust ventilator of Chinese patent CN2314269Y, comprise porous inlet side panel, the metal oil separator, motor, wind wheel, and spiral case, round air-flow radome fairing, exhaust outlet, oil sump tank, parts such as motor cover, wherein porous air intake side plate is positioned at the Lower Half of whole lampblack absorber, and the angle of the metope of this air intake side plate and installation is the 15-30 degree, such air intake plate is near the oil smoke source, the smoke pumping effect is preferable, but the wind wheel of this smoke exhaust ventilator is positioned at the top of whole lampblack absorber, still very high from the kitchen range top, therefore influenced suction effect.Therefore, have the range hood that some move down blower fan again, as the disclosed hood of Chinese patent CN1084263A, the main body of this hood is an approximate right angle triangle, by backboard, it plate and left side plate constitute, also comprise and be accommodated in the ventilating device in the hood main body and be positioned at the metal filtration spare of hood the place ahead towards the user, but such range hood, because the blower fan position is low, substantially approach people's ear, air inlet is directly towards the user, and the import noise that blower fan produces is directly received by people's ear, so cause noise bigger than normal, and in order to form the negative pressuren zone of to a certain degree concentrating, must suitably dwindle the cowling panel air inlet, and dwindle the cowling panel air inlet, certainly will increase noise.
Summary of the invention
Technical problem to be solved in the utility model is the close-suction range hood that a kind of low noise is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of rectifying noise-reduction close-suction range hood, comprise casing, the panel that tilts towards the user on the casing, be positioned at the fan assembly of panel rear, casing inside, be positioned at air intake vent on the panel and the air outlet on the casing, it is characterized in that: the air inlet of described fan assembly panel is dorsad installed, and the rectification passage of described air intake vent connection casing inside causes the wind that sucks the air inlet of fan assembly.
As first embodiment of the present utility model, for inspiration oil smoke better more promptly prevents the oil smoke diffusion, described air intake vent is positioned at the bottom of panel.
And for the oil smoke of rectification suction and the noise of reduction complete machine, described air intake vent is a strip, described rectification width of channel reduces gradually, air intake vent from the panel is contracted to the air inlet of fan assembly, and described rectification passage is at the air intake vent place, extend one section downwards earlier, extend upwardly to the air inlet of fan assembly again along the backboard of casing.
Be positioned at the top of panel as the described air intake vent of second embodiment of the present utility model.
And oil smoke that sucks for rectification and the noise that reduces complete machine, described air intake vent is a strip, and described rectification width of channel reduces gradually, and the air intake vent from the panel is contracted to the air inlet of fan assembly.Described rectification passage begins the backboard that fan assembly upside in the casing extends to casing from described air intake vent, extends downward the air inlet of fan assembly again along the backboard of casing.
As the 3rd embodiment of the present utility model, for inspiration oil smoke better, prevent the diffusion of oil smoke, described air intake vent is two, lays respectively at the upper and lower of panel, described rectification passage also is arranged to upper and lower two accordingly.
Preferably, described two air intake vents are respectively strip.The described rectification passage of going up begins the backboard side that fan assembly top in the casing extends to casing from described top air intake vent, extend downward the air inlet of fan assembly again along the backboard of casing, described rectification passage down is at bottom air intake vent place, extend downward the backboard side earlier, extend upwardly to the air inlet of fan assembly again along the backboard of casing.
For the ease of installing and lampblack absorber more reasonable structure compactness, described air outlet being positioned on the top board of casing top, the air outlet of fan assembly is connected to this air outlet by the air-out passage.
Compared with prior art, advantage of the present utility model is the air inlet panel installation dorsad with fan assembly, in prior art, install towards panel, reduced the noise of range hood more, and, not only can further reduce the noise of complete machine by the rectification of rectification passage, it is relatively even to make that the air intake vent air intake distributes, thereby improve oil suction cigarette effect, and use single blower fan can reach the effect of two blower fans equally, thereby reduce cost.
