Abstract

The utility model relates to an oil fume exhausting purifying machine which is the improvement of the existing oil fume air exhaust fan, which comprises a casing, wherein, the interior of the casing is provided with a centrifugal fan and a volute; an air outlet of the volute at the lower part in the casing is provided with a porous filtering plate; a wind draining port is arranged on the rear side under the casing; the bottom of the casing is provided with an oil collecting device. The utility model has the advantages of strong suction force and high wind pressure and can cause oil fumes in a cooking stove to be removed quickly. Sucked and drained oil fumes can be separated and filtered in the fan, achieving effective purification so as to reduce the pollution to the environment and the air. The utility model is especially suitable for being matched with oil fume sucking and draining cooking stoves of a semi-closed window type.

Description

Oil smoke suction clearing machine

The utility model relates to a kind of kitchen range that is suitable for and uses, is particularly suited for disposing the oil smoke suction clearing machine that uses with the semiclosed window formula fume exhaust kitchen range top, and it is the further improvement to existing oil smoke ventilating fan.

At present, had the oil smoke ventilating fan of multiple structure,, in use still exposed some shortcomings though they all have pump drainage oil smoke effect preferably.One adopts axial flow blower, and blast is lower, and the suction force of wind is powerful inadequately, and when windage was big, suction effect obviously reduced; Its two, no filtration, purification and oil collector sump tank or the simple filtering guard is only arranged, outdoor by the unprocessed direct discharge of the oil smoke of pump drainage, oil smoke mixes, and causes the pollution to surrounding environment and air; The 3rd, because no purification filtering and oil collector sump tank, use many greasy dirts after a period of time to glue to collect in the ventilating fan and the air door place of air outlet, not only be difficult to removing, but also influence the pump drainage effect of ventilating fan.

The purpose of this utility model is to provide a kind of pump drainage wind-force strong at the existing deficiency of existing ventilating fan, the oil smoke suction clearing machine that the oil smoke isolation of purified is effective.

The purpose of this utility model is realized by following technical scheme: include a casing 7, its difference is to install a centrifugal blower and disposes spiral case 4 in casing, the air outlet place of spiral case is provided with porous filter plate 10 below in casing, exhaust outlet 12 is arranged on casing below rear side, is provided with oil collector sump tank at bottom of shell.

The utility model has the advantages that: 1, adopt centrifugal blower, suction force is strong, the blast height, can make in the kitchen range oil smoke by in time promptly pump drainage go out; 2, oil smoke is revolved in spiral case and throw to be separated under the effect of centrifugal blower, and the filtration of pulling through the filter of air outlet place porous through twice oil removal treatment, is separated most of oil gas again, is effectively purified, and can reduce pollution to air and environment from face; 3, spiral case and oil collector sump tank are set, the oil of separating is reclaimed timely, avoid the productive set of greasy dirt in blower fan, also help the purification of environment.

Fig. 1 is the front view of an embodiment of the utility model.

Fig. 2 is the sectional view of Fig. 1.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, has a casing 7, be installed on a centrifugal blower in the casing, centrifugal blower is made of turbine fan blade 2 and motor 8, dispose spiral case 4 in turbine fan blade periphery, spiral case can be linked into one with casing, is equipped with a panel 1 in the front of casing, offers air inlet on the panel, the air inlet place is equipped with protection network 3, perhaps install filtering screen at the air inlet place, in casing below the air outlet place of spiral case be provided with an arc porous filter plate 10, the rear side below casing is offered exhaust outlet 12, can pacify air-out valve 9 at the exhaust outlet place, automatically open during air draft, time spent air-out valve is not closed, in case the dust storm mosquitos and flies enters.According to circumstances, exhaust outlet also can directly join with shared flue, makes the flue gas after the separation enter flue, and lower bottom part is provided with the oil guide groove of introversion in casing, junction in oil guide groove is provided with oil-out, the outer inferoanterior lubricating cup 6 of oil-out and casing is connected, and constitutes oil collector sump tank thus, in addition, below panel, also can install wind deflector 11, to weaken suction to kitchen range fire door top wind, prevent to go here and there on the flare, electric-controlled switch 5 can be positioned on the below of panel.
