Abstract

The utility model discloses a quiet near extraction type range hood with high efficiency and low carbon emission. A connection frame is arranged at the middle upper part of a negative pressure box of the near extraction type range hood. A vertical negative pressure generation device is fixedly connected with the connection frame through bolts, an impeller of the vertical negative pressure generation device is long cylindrical, and a windmill screen of the vertical negative pressure generation device is a semi-open cambered hollow body. A conveniently-replaceable automatic oil fume separation device is arranged at an oil fume extraction opening of the negative pressure box. A negative pressure guide housing is arranged outside the oil fume extraction opening. Due to the adoption of the vertical negative pressure generation device, the automatic oil fume separation device and the negative pressure guide housing, after oil fume passes through the automatic oil fume separation device and the vertical negative pressure generation device under the effective control of the negative pressure guide housing, waste oil and smell are timely separated and automatically decomposed and recycled, and a gas is emitted.

Description

The near-absorption type smoke exhaust ventilator of a kind of mute type high efficiency, low-carbon emission

Technical field:

The utility model belongs to a kind of smoke exhaust ventilator, refers in particular to a kind of family, the catering trade near-absorption type smoke exhaust ventilator with mute type high efficiency, low-carbon emission.

Background technology:

Existing market near-absorption type smoke exhaust ventilator salable; All adopt impeller, the wind drum of flat; When the impeller propelled air was discharged from the air outlet of wind drum, impacting at the wind drum that air-flow is comparatively concentrated was connected on the dead angle of discharge pipe with air outlet, therefore produced the wind ring; Add the sympathetic response of the casing of part under the near-absorption type smoke exhaust ventilator, produced annoying noise when making the work of near-absorption type smoke exhaust ventilator.Existing near-absorption type smoke exhaust ventilator; Also lack automatic flushing device and negative pressure and concentrate guide housing, not only artificial cleaning strength is big, the pollution that oil stain that gives off and smell are serious environment; And the fume exhaust effect is also bad, is unfavorable for that indoor health and operator's is healthy.

Summary of the invention:

The utility model provides that a kind of mute type is efficient, the near-absorption type smoke exhaust ventilator of low-carbon emission; When purpose is the work of near-absorption type smoke exhaust ventilator; Oil smoke is under effective control of negative pressure guide housing; Behind automatic oil-fume separating device and vertical negative pressure generation device, waste oil and smell divide in time to be isolated and decomposition recovery automatically, and gas is discharged.Like this, make the casing of near-absorption type smoke exhaust ventilator inside and outside with the oil-fume separating device neat and tidy, reached low noise and low-carbon emission, be of value to the elegant of indoor and resident community environment.

To achieve these goals; The technical scheme of the utility model is: the middle and upper part at near-absorption type smoke exhaust ventilator negative pressure box is provided with link; Impeller is that elongated cylindrical and wind drum are the vertical negative pressure generation device of semi open model arc shape hollow body, is fixedly connected with link through bolt.At negative pressure box oil suction mouth place, be provided with conveniently replaced automatic oil-fume separating device, oil suction mouth peripheral hardware has the negative pressure guide housing.

The top of the rectangle outlet flue that vertical negative pressure generation device top is provided with is connected with the discharge pipe of rectangular change pipe, and the pipe of discharge pipe upper end connects smoke exhaust pipe.

The negative pressure guide housing is a totally enclosed type, or the below opening is semi-enclosed.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1. be the utility model primary structure perspective view

Fig. 2. be the left view of the utility model Fig. 1

Among the figure: 1. negative pressure box, 2. vertical negative pressure generation device, 3. automatically oil-fume separating device, 4. discharge pipe, 5. link, 6. negative pressure guide housing.

The specific embodiment:

Like Fig. 1, shown in 2: be provided with link (5) in the middle and upper part of near-absorption type smoke exhaust ventilator negative pressure box (1), impeller is that elongated cylindrical and wind drum are to be fixedly connected the vertical negative pressure generation device (2) of semi open model arc shape hollow body with link (5) through bolt.At negative pressure box (1) oil suction mouth place, be provided with conveniently replaced automatic oil-fume separating device (3).Outside negative pressure box (1) oil suction mouth, be provided with negative pressure guide housing (6).

The top of the rectangle outlet flue that vertical negative pressure generation device (2) top is provided with is connected with the discharge pipe (4) of rectangular change pipe, and the pipe of discharge pipe (4) upper end connects smoke exhaust pipe.

The utility model is to implement like this:

Like Fig. 1, shown in 2: during the work of near-absorption type smoke exhaust ventilator; Oil smoke is under effective control of negative pressure guide housing (6); Behind automatic oil-fume separating device (3) and vertical negative pressure generation device (2); Waste oil and smell divide in time to be isolated and decomposes automatically and reclaim, and gas behind the discharge pipe (4) through rectangular change pipe and the smoke exhaust pipe, is discharged in the concentrated delivery pipe smoothly.
