Abstract
The utility model provides an exhaust duct that over-and-under type smoke ventilator used which characterized in that: the exhaust pipeline is composed of a corrugated bent pipe 1, a fixed sleeve 2 and a telescopic sleeve 3, wherein an inner edge rolling is arranged at a lower port of the fixed sleeve 2, an outer edge rolling is arranged at an upper port of the telescopic sleeve 3, the telescopic sleeve 3 is arranged in the fixed sleeve 2 from top to bottom, the upper end of the fixed sleeve 2 is arranged at the inner side of the lower end of the corrugated bent pipe 1, the lower port of the telescopic sleeve 3 is fixedly connected with an exhaust port of a smoke exhaust ventilator, and the outer side of the superposition position of the fixed sleeve 2 and the corrugated bent pipe 1 is fixed on a wall body by a fixing frame. Compared with the prior art, the utility model has the advantages that: this exhaust duct adopts telescopic pipeline, and each section sleeve pipe concatenates through setting up the border at its port, and the sleeve pipe diameter that is located next section is less than the sleeve pipe diameter of its last section, with the help of smoke ventilator exhaust fan's effect, makes the discharge that the flue gas can be smooth and easy, and the junction between difficult follow sleeve pipe and the sleeve pipe of flue gas is escaped at carminative in-process, plays the positive role for realizing green kitchen.
Description
Technical field
The utility model relates to a kind of discharge duct that is used with elevating cooker hood.
Background technology
As everyone knows, after traditional smoke exhaust ventilator is installed, distance between this machine lower edge and the kitchen range face is fixed, be 700～800mm, yet it is very greatly that the exhaust gas volumn of distributing in different cooking operation processes changes, and particularly during fried food, flue gas sharply increases, there have a considerable amount of flue gases to spread in to be indoor, produces to pollute.Someone designs multiple elevating cooker hood, the exhaust gas volumn difference that produces during according to the cooking, regulate the distance between smoke exhaust ventilator lower edge and the kitchen range face, during as fried food, the distance of regulating between smoke exhaust ventilator lower edge and the kitchen range face is 300～400mm, make the indoor smoke pollution that is subjected to less or is not subjected to, use comparatively desirable discharge duct but lack so far to match with elevating cooker hood.
Summary of the invention
The discharge duct that a kind of elevating cooker hood is used, it is characterized in that: this discharge duct is made of ripple bend pipe 1, fixed sleeving 2, telescopic tube 3, wherein fixed sleeving 2 lower port are provided with interior rolling, telescopic tube 3 upper port are provided with outer rolling, telescopic tube 3 is contained in rear flank in the fixed sleeving 2 from top to bottom, fixed sleeving 2 upper ends are contained in inboard, ripple bend pipe 1 bottom, telescopic tube 3 lower port are fixedlyed connected with the smoke exhaust ventilator exhaust outlet, and fixed sleeving 2 adopts fixed mount 4 to be fixed on the body of wall with the outside, superimposed place of ripple bend pipe 1; Telescopic tube 3 is formed by 2 joints or the above sleeve combination of 2 joints, rolling and interior rolling outside wherein its upper port of sleeve pipe between minor details sleeve pipe and fixed sleeving 2 and lower port are respectively equipped with, after ripple bend pipe 1, fixed sleeving 2, telescopic tube 3 combinations, minor details cover infratubal port is fixedlyed connected with the exhaust outlet of smoke exhaust ventilator, and the flexible amplitude of telescopic tube 3 is not more than 400mm.
With prior art relatively, the utility model has the advantages that: this discharge duct adopts telescopic pipeline, each saves sleeve pipe by being arranged on the rolling serial connection of its port, and the little casing diameter of a joint thereon of the casing diameter that is positioned at next joint, effect by the smoke exhaust ventilator exhaust fan, flue gas can be discharged smoothly, and flue gas is difficult for escaping from from the junction between sleeve pipe and the sleeve pipe in the process of exhaust, has a positive effect for realizing green kitchen.
