Abstract

A flow guiding type smoke exhaust ventilator comprises an axial flow fan with low noise and back entrance bucket, a smoke exhausted cover, a flow guiding pipe and a controller. The utility model is used for the smoke exhaustion in the kitchen, belonging to the kitchen technical field. The clearing rate of the prior smoke exhaust ventilator is low, and some of the smoke exhaust ventilators cannot be imagined. Some make the improvement such as the deep-cover smoke exhaust ventilator, but the volume is large, which has an oppressed feeling. The design creates the flow guiding technology, and not only the clearing rate can be greatly increased, but also the electricity can be saved. The utility model is propitious to the miniaturization and ultra-thin type. The main technical characteristic is that the flow guiding pipe is arranged under the smoke exhausted cover in the near wall.

Description

The flow-guiding type range hood

The utility model is a kind of range hood, and it relates to a kind of flow-guiding type range hood that improves clean absorption rate with method of river diversion.

This flow-guiding type range hood is to be used for absorbing oil smoke in the kitchen, belongs to kitchen guarding's technical field.

In existing range hood technology, form by lampblack-sucking cover, exhaust blower, controller and light fixture etc. usually, but the low problem of ubiquity clean absorption rate, some is low as to be difficult to imagine.In order to improve clean absorption rate, people manage to improve on exhaust blower pattern on the suction, for example dark bell-type range hood.Though clean absorption rate increases, this type volume is big, gives sense of depression, and energy consumption is big, and the cost height influences its competitiveness to a certain extent.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of flow-guiding type range hood that improves clean absorption rate with method of river diversion is provided.The flow-guiding type range hood can not only increase substantially clean absorption rate, and can dwindle the size of lampblack-sucking cover, in order to ultra-thin moulding.So-called water conservancy diversion is exactly that a vertically disposed mozzle is arranged in the middle of one side of the nearly wall of lampblack-sucking cover, its cross section is up big and down small like triangle, the higher authorities inject the heavy in section lampblack-sucking cover and communicate with the air inlet of axial flow blower, mozzle be provided with mesh as suction nozzle towards the oil smoke face, establish catchment cup at its microcephaly's lowest part, the route that oil smoke rises during operation can tilt to mozzle, this just stops dispersing of oil smoke effectively, improve clean absorption rate, the covering size of dwindling lampblack-sucking cover, favourable ultra-thin moulding.

The purpose of this utility model is achieved like this: it comprises the low noise axial fan of establishing rear guide vane, lampblack-sucking cover, mozzle, electrical equipment lamp box etc.If the conical shell of the low noise axial fan of rear guide vane, the adapter of double as flue, its major part and lampblack-sucking cover mesopore join, and microcephaly and smoke exhaust pipe join.Lampblack-sucking cover is shaped as thin formula fillet rectangle, and middle circle orifice plate limit and blower fan conical shell head join.Bar shaped herringbone electrical equipment lamp box is located at longitudinal subdivision in the lampblack-sucking cover, and two suction nozzles were corresponding with the eyes kitchen range about lampblack-sucking cover was divided into, and suction nozzle is established oil cleaner screen.The mozzle cross section is up big and down small like triangle, and major part injects lampblack-sucking cover and communicates with the axial flow blower air inlet, and mozzle is provided with mesh and makes suction nozzle towards the oil smoke one side, and its microcephaly is that lowest part is established catchment cup.

The utility model has following advantage: 1 owing to having started the mozzle technology, so can increase substantially clean absorption rate; 2 power consumptions are low; 3 moulding are light and handy.

Further set forth the concrete enforcement of technical solutions of the utility model below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model

Fig. 2 is the structural representation of the left side view of Fig. 1

See Fig. 1, catchment cup 1 is located at the lowest part of mozzle.Mozzle 2, its suitable for reading and axial flow blower inlet communicates, mozzle be provided with the mesh suction nozzle towards the oil smoke face, produce low pressure during operation near the mozzle, the oil smoke that rises is sucked flue gas is discharged from after oil cleaner screen 11 filters.Lampblack-sucking cover 3 is to absorb the oil smoke that part rises.This cover is by electrical equipment lamp box and two suction nozzles corresponding to the eyes kitchen range about the mozzle longitudinal subdivision becomes, and loads onto oil cleaner screen 5, and oil smoke flue gas behind oil cleaner screen 5 is discharged from, and oilyly is aggregated into catchment cup 1 through oil duct.All the other title numberings are as follows: oil-resistant rubber insert 6, low noise axial fan 7, rear guide vane 8, rectification cone 9, conical shaft flow fan housing 10, mozzle oil cleaner screen 11.Arrow is represented the oil smoke flow process among the figure.

The applicant thinks that best implementation is to look for the enterpriser that the competition great ambition is arranged.This product has innovation, power savings advantages, perhaps can become the main product of update.

Claims

1 one kinds of flow-guiding type range hoods, comprise and establish rear guide vane low noise axial fan, lampblack-sucking cover, mozzle etc., if the housing of rear guide vane low noise axial fan is conical double as fume tube joint, major part is connected with the lampblack-sucking cover mesopore, microcephaly's fume tube that runs in.Lampblack-sucking cover is thin formula rectangle, strip herringbone electrical equipment lamp box longitudinal subdivision lampblack-sucking cover, two suction nozzles about being divided into, and dress oil cleaner screen.Be positioned at the central mozzle of the nearly wall of lampblack-sucking cover on one side, its cross section is subtriangular, and is up big and down small, major part communicates with the axial flow blower inlet, establish mesh on the oil smoke face and make suction nozzle, the microcephaly establishes catchment cup, it is characterized in that: the nearly wall in lampblack-sucking cover below is established mozzle on one side.

2 a kind of flow-guiding type range hoods according to claim 1 is characterized in that: establish rear guide vane low noise axial fan housing and be the conical flue tube joint of holding concurrently.
