Abstract
A smoke removal down draft resistant structure of a water heater comprises a smoke collecting hood at the bottom of which a smoke collecting port is formed, wherein a smoke outlet is formed at the top of the smoke collecting hood, and a unidirectional windshield valve piece which corresponds to the upper part of the smoke collecting port and slides vertically is arranged in the smoke collecting hood; a bottom cover is arranged at the bottom of the smoke collecting hood, the smoke collecting port is formed on the bottom cover, and a smoke collecting tube which is connected with the smoke outlet formed at the top of the water heater is arranged on the smoke collecting port; at least one slide bar is arranged inside the smoke collecting hood vertically, the unidirectional windshield valve piece is arranged above the smoke collecting tube, and the slide bar penetrates the unidirectional windshield valve piece for sliding connection; and the unidirectional windshield valve piece is a thin sheet with a circular arc-shaped vertical cross section, and the size of the unidirectional windshield valve piece is greater than the pipe orifice of the smoke collecting tube and less than the inner diameter of the smoke collecting hood. By virtue of the smoke removal down draft resistant structure, hot flue gas drives the unidirectional windshield valve piece to slide upwards when the water heater operates, and the smoke collecting hood is communicated with the outside and exhausts normally; moreover, the unidirectional windshield valve piece vertically slides downwards under deadweight action so as to cover the smoke collecting tube when the water heater does not operate, and external wind and small organisms can be prevented from entering the inner part of the water heater.

Background technology
I disclose a kind of anti-down wind mechanism of smoke evacuation of water heater on April 11st, 2007 in Chinese patent literature CN2888290, comprise the smoke exhaust pipe that can be socketed in the water heater top, and its smoke exhaust pipe lower, transverse is provided with a unidirectional valve block that keeps out the wind.The inwall of smoke exhaust pipe is welded with the sheet bearing, and a lever pin is run through at the two ends of bearing, and the unidirectional valve block that keeps out the wind is applied on the lever pin.Described lever pin is eccentric to be provided with, and the unidirectional valve block that keeps out the wind is a dried mushroom shape.Or lever pin centering is arranged on the diametrical position of smoke exhaust pipe, and the unidirectional valve block that keeps out the wind is two semicircles, and is middle hinged by lever pin.It adopts the outlet flue at water heater, and promptly the smoke exhaust pipe bottom transverse is provided with the technical scheme of the unidirectional valve block that keeps out the wind, and sheet bearing and lever pin are arranged in the smoke exhaust pipe, overall appearance, and flue gas can not leak outside.When not working, the unidirectional valve block that keeps out the wind covers outlet flue under the deadweight effect, prevents that cockroach and small insect and so on from entering.During work, under the drive of forced-ventilated blower fan, the unidirectional valve block that keeps out the wind is opened, normal smoke discharging.It is simple and reasonable, and the unidirectional valve block switch that keeps out the wind is flexible, practical.But owing to this mechanism is the unidirectional valve block design of keeping out the wind of semi-open type, ventilation effect is unsatisfactory, is necessary further improvement and perfect.
The utility model content
The purpose of this utility model aims to provide a kind of smoke evacuation simple and reasonable, that make the water heater simple, that ventilation effect is desirable and prevents the down draught structure, to overcome weak point of the prior art.
Press the anti-down draught structure of smoke evacuation of a kind of water heater of this purpose design, comprise exhaust fume collecting hood, the exhaust fume collecting hood bottom is provided with smoke collecting port, and the exhaust fume collecting hood top is provided with outlet flue, and its architectural feature is the unidirectional valve block that keeps out the wind that the top of the inner corresponding smoke collecting port of exhaust fume collecting hood is provided with vertical slip.
Described exhaust fume collecting hood bottom is provided with bottom, and smoke collecting port is arranged on the bottom, and smoke collecting port is provided with
The smoke collection pipe that is connected with water heater top exhaust opening; The exhaust fume collecting hood top is provided with top cover, and outlet flue is arranged on the top cover, and outlet flue is provided with the pipe that is connected with smoke discharging pipe.
Described exhaust fume collecting hood bottom is provided with bottom, and smoke collecting port is arranged on the bottom, and smoke collecting port is provided with the smoke collection pipe that is connected with water heater top exhaust opening; Vertically be provided with at least one slide bar in the exhaust fume collecting hood, the unidirectional valve block that keeps out the wind is arranged on smoke collection pipe top, and slide bar passes the unidirectional valve block that keeps out the wind and forms with it and be slidingly connected.
The described unidirectional valve block that keeps out the wind is that vertical section is circular-arc thin slice, and its mouth of pipe than smoke collection pipe is big, littler than exhaust fume collecting hood internal diameter.
Described exhaust fume collecting hood top is provided with top cover, and outlet flue is arranged on the top cover, and outlet flue is provided with the pipe that is connected with smoke discharging pipe; The pipe bottom is provided with the slide bar fixed cap, and slide bar is fixed on the slide bar fixed cap, and the tube wall that pipe puts in bottom is provided with air-vent.
Described exhaust fume collecting hood inside is provided with the slide bar fixed cap, and slide bar is fixed on the slide bar fixed cap, and the slide bar fixed cap is provided with air-vent.
The geometric center of the described unidirectional valve block that keeps out the wind, smoke collection pipe, slide bar fixed cap is on same straight line
Owing to by technique scheme, make the utility model overall appearance, hot flue gas drives the unidirectional valve block that keeps out the wind and up slides the extraneous and normal exhaust of exhaust fume collecting hood connection during water heater working; When water heater was not worked, the unidirectional valve block that keeps out the wind covered smoke collection pipe because the deadweight effect is vertically glided, and prevented that extraneous wind and small-sized biology from entering in the water heater and influence the work of water heater.
