Abstract
The invention relates to a silence type efficient and low carbon emission near-suction type oil fume exhaust ventilator, which mainly comprises a negative pressure box, an oil fume separation plate and a gas exhaust pipeline, and is characterized in that the middle-upper part of the negative pressure box of the near-suction type oil fume exhaust ventilator is provided with a connection frame, a vertical negative pressure generation device having a long cylindrical blade wheel and a semi-open type arc-shaped hollow air blast body is fixedly connected with the connection frame through bolts, an oil fume suction port position on the negative pressure box is provided with an easily-replaced automatic oil fume separation device, and a negative pressure guiding cover is arranged outside an oil fume suction port. According to the present invention, the vertical negative pressure generation device, the automatic oil fume separation device and the negative pressure guiding cover are adopted, oil fume passed through the automatic oil fume separation device and the vertical negative pressure generation device under effective control of the negative pressure guiding cover, waste oil and odor are timely separated and subjected to automatic decomposition recovery, and the gas is discharged.
Description
Technical field:
Type of the present invention belongs to a kind of smoke exhaust ventilator, refers in particular to the near suction range hood of a kind of family, catering trade mute type high efficiency, low-carbon emission.
Background technology:
Existing market near suction range hood salable, all adopt impeller, the wind drum of flat, when the impeller propelled air is discharged from the air outlet of wind drum, impacting at the wind drum that air-flow is comparatively concentrated is connected on the dead angle of discharge pipe with air outlet, therefore produced the wind ring, add under the near suction range hood sympathetic response of the casing of part, so that produced annoying noise during near suction range hood work.Existing near suction range hood, also lack automatic flushing device and negative pressure and concentrate guide housing, not only manual cleaning intensity is large, the pollution that the 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:
Type of the present invention provides that a kind of mute type is efficient, the near suction range hood of low-carbon emission, when purpose is near suction range hood work, oil smoke is under effective control of negative pressure guide housing, behind automatic oil-fume separating device and vertical negative pressure generating device, waste oil and smell divide in time to be isolated and automatic recovery, and gas is discharged.Like this, so that the casing of near suction range hood is inside and outside and the oil-fume separating device neat and tidy, reach low noise and low-carbon emission, be of value to the elegant of indoor and residential communities environment.
To achieve these goals, the technical scheme of type of the present invention is: the middle and upper part at the near suction range hood negative pressure box is provided with link, impeller is that elongated cylindrical and wind drum are the vertical negative pressure generating device of semi open model arc shape hollow body, is fixedly connected with link by 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 generating 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 totally enclosed type, or the below opening is semi-enclosed.
Description of drawings:
Below in conjunction with accompanying drawing type of the present invention is described further:
Fig. 1. be type primary structure perspective view of the present invention
Fig. 2. be the left view of type Fig. 1 of the present invention
Among the figure: 1. negative pressure box, 2. vertical negative pressure generating device, 3. automatically oil-fume separating device, 4. discharge pipe, 5. link, 6. negative pressure guide housing.
The specific embodiment:
As shown in Figure 1, 2: be provided with link (5) in the middle and upper part of near suction range hood negative pressure box (1), impeller is that elongated cylindrical and wind drum are to be fixedly connected with the vertical negative pressure generating device (2) of semi open model arc shape hollow body with link (5) by 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 generating 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.
Type of the present invention is to implement like this:
As shown in Figure 1, 2: during near suction range hood work, oil smoke is under effective control of negative pressure guide housing (6), behind automatic oil-fume separating device (3) and vertical negative pressure generating device (2), waste oil and smell divide in time to be isolated and automatic recovery, behind the smooth discharge pipe (4) and smoke exhaust pipe by rectangular change pipe of gas, be discharged into and concentrate in the delivery pipe.
