Description

Grouped oil-collecting self-suction cooking fume exhauster

The utility model relates to a kind of air joint device that withers, especially a kind of culinary smoke exhaust.

At present, known smoke exhaust for kitchen use generally is placed in the top of kitchen range, and a blower fan is respectively arranged about this smoke exhaust, and fan blade rotates by driven by motor, thereby forms suction airstream upwards, with oil smoke suck be discharged to by tracheae again in the blower fan outdoor.Thereby make outdoor environment be subjected to discharging the pollution of flue gas.This exhaust blower is in the smoke evacuation process, and the high-temperature oil smoke long duration of action not only influences fan life in blower fan, and needs frequent disassembly, cleaning, in case cleaning method is improper or untimely, water clock sump oil phenomenon will occur, makes troubles for normal the use.

The purpose of this utility model provides a kind of long service life, cleaning frequency is long and simple and convenient, and can will collect behind a part of oil liquify contained in the oil smoke, thereby reduce pollution to environment, the oil-collecting type in groups safe and reliable, that smoke pumping is effective---self-priming fume exhauster.

The purpose of this utility model is achieved in that

The utility model comprises single blower fan, two blower fan or multi fan, it is characterized in that: the outlet of every typhoon machine directly be positioned at exhaust fume collecting hood on greatly the reducing air jet pipe of flared pipe one end of tripe horn mouth threeway be connected; The bell-mouthed root of the flared pipe other end of big tripe horn mouth threeway is connected with oil extraction smoke pipe one end, and the other end of oil extraction smoke pipe is connected with primary exhaust conduit one side; Every successively typhoon machine reducing air jet pipe and the threeway of big tripe horn mouth, the oil extraction smoke pipe is arranged equally, is connected with main exhaust respectively; Every typhoon machine and big tripe horn mouth threeway instrument respectively are fixed on the cover body top, and each big tripe horn mouth three passes in the central tube mouth insertion exhaust fume collecting hood and is connected with exhaust fume collecting hood inside.

---the exhaust fume collecting hood body is that top and bottom are isometric rectangles, top rectangular is wide wide less than bottom rectangle, both sides are that an identical right-angled trapezium prescinds one right angle, top and becomes traverse behind the hypotenuse, form that high back is low before the cover body bottom recedes, and the cover body front upper part leaves five length of side bar cover bodies on an inclined-plane; The cover body top rectangular is opened the round mouth of two symmetries or a plurality of even layouts according to the number of blower fan group, the middle part pipe of the big tripe horn mouth threeway of both ends open is connected on each round mouth and the cover body, at the cover body inner-use clapboard with each round mouth separately, the end of arc, is along fixing with the rectangle swash plate; Size rectangle swash plate lower edge overlaps with front and back, cover body base oil guide groove respectively, and position, big or small rectangle swash plate upper edge is under cover body front upper part inclined-plane; Base, cover body lower edge oil guide groove interconnects, and both sides recede, and is lower than both sides in the middle of the oil guide groove of back, and middle lower oil collection box is connected.

The utility model, owing to adopt said structure, when opening each blower fan respectively or simultaneously, wind is blown into the reducing air jet pipe by blower fan, the air-flow that the reducing air jet pipe outwards penetrates is accelerated, and both sides air pressure reduces simultaneously, produces negative pressure, thereby the gas of big tripe horn mouth threeway central tube bottom is upwards aspirated, make under the exhaust fume collecting hood oil smoke risen by suction and up along rectangle swash plate and cover body upper inclined surface.At oil smoke along big or small swash plate, when the cover body upper inclined surface is up, contained a part of oil attaches gradually on big or small rectangle swash plate and cover body upper inclined surface and forms oil droplet in the oil smoke, owing to, make oil droplet flow into oil guide groove income oil collection box along each inclined-plane by the effect of big or small swash plate and cover body upper inclined surface.Another part oil smoke is inhaled in the big tripe horn mouth threeway middle part pipe on big or small swash plate and top, cover body inclined-plane.Oil smoke enters smoke exhaust pipe by the speedup supercharging of threeway horn mouth place, enters the main comb back of turning by a side of gas exhaust piping respectively and discharges outdoor by primary exhaust conduit.Because oil smoke is subjected to the influence of reducing air jet pipe air-flow air pressure by threeway horn mouth place, make the supercharging of oil smoke speedup, the composition of oil collides mutually to form to be detained behind the oil droplet and wants to liquefy behind the turning in the cigarette, flows into the oil collection box of setting.Reduced the interior dirt of cigarette like this to outdoor discharging, reduced pollution outdoor environment.Because high-temperature oil smoke does not pass through blower fan, directly introduce oil exit pipe and enter primary exhaust conduit and discharge, solved general smoke exhaust blade and motor and directly be subjected to baking, erosion, the trouble that must on time clean and the untimely cleaning blade of high-temperature oil smoke gas and the casing will oil dripping thing defective by the exhaust fume collecting hood body.The utility model only needs the life-span according to pipe, blower fan and accessory, changes spare part by certain time limit and gets final product.Easy removal, it can design multimachine and single, double machine as required simultaneously, and wide application can be widely used in restaurant, dining room and family kitchen.Provide convenience for keeping environment, reduce polluting.

The oil that the utlity model has liquefaction soot gas inside reduces pollution, not influenced by high temperature and long-time adverse circumstances etc., long service life, and maintenance is cleaned convenient, safe and reliable characteristics.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structure chart of the present utility model.
