Abstract

The utility model relates to an anti-downdraft smoke tube of a water heater, comprising a smoke tube. The head end of the smoke tube is connected with the flue of the water heater, the tube body and the tail end of the smoke tube extend to the outdoor, the inside of the tail end of the smoke tube is rotatably connected with a valve plate, and a tube wall wind guide facility is arranged on the tube body of the smoke tube. The tube wall wind guide facility comprises wind guide holes and wind guide tongue pieces, wherein the wind guide holes are uniformly distributed on the tube body of the smoke tube, the wind guide tongue pieces are arranged inside the tube body of the smoke tube corresponding to the positions of the wind guide holes, the wind guide holes are in D shapes or rectangular shapes, the shapes of the wind guide tongue pieces are consistent with those of the wind guide holes, the wind guide tongue pieces are inclined relative to the air-out direction, and the wind guide holes and the wind guide tongue pieces are integrally formed through stamping the tube body of the smoke tube. The utility model can effectively prevent external wind from flowing backward to the inside of the water heater. In addition, the wind guide holes and the wind guide tongue pieces are arranged on the tube body of the smoke tube, thereby when the smoke tube encounters surrounding wind blowing, the wind guide tongue pieces on the wind guide holes can change the direction of wind entering the smoke tube and enable the wind to be smoothly discharged out of the smoke tube, and even strong wind invades, the wind can not flow backwards into the water heater.

Description

The anti-down wind and smoke pipe of water heater

Technical field

The utility model relates to a kind of anti-down wind and smoke pipe, specifically is the anti-down wind and smoke pipe of a kind of water heater.

Background technology

Along with people's living standard improves constantly, present water heater operated by rotary motion has smoke discharging pipe, irritates to water heater for avoiding outdoor wind-fall, is provided with anti-down wind mechanism on the smoke discharging pipe usually, to guarantee the normal use of water heater.Chinese patent literature CN201233017 discloses the anti-down wind apparatus of a kind of gas heater flue on May 6th, 2009, be arranged on the gas heater flue, it is characterized in that, this device is included in the pipeline section of socket on the gas heater flue tube, the pipeline section upper end is provided with a rotating shaft, rotating shaft is provided with a blanking cover that is complementary with bore, and this blanking cover is along the oblique setting of air-out direction in the pipe.Described pipeline section is socketed on the gas heater flue external diameter, and the external diameter of blanking cover is greater than the jacketted flue internal diameter; The gas heater flue end of described socket is the inclined plane, is in outward-dipping blocked state to keep blanking cover when blocking up wind.It is said that it has advantages such as simple in structure, that result of use is good.One side of this device also is provided with an osculum pipeline section, has the plurality of rows pore on this pipeline section, still, when meet high wind from around when blowing to this pipeline section, can form eddy-currents in that pipeline section is inner, thereby damage this pipeline section, be necessary to be improved.

The utility model content

The purpose of this utility model aim to provide a kind of simple and reasonable, make simple, ventilation effect is desirable, can resist the anti-down wind and smoke pipe of water heater that high wind blows, to overcome weak point of the prior art.

The anti-down wind and smoke pipe of a kind of water heater by this purpose design, comprise smoke pipe, the head end of smoke pipe is connected with water heater flue, and the pipe shaft of smoke pipe and tail end stretch out outdoor, the tail end inner rotation of smoke pipe is connected with valve block, and its architectural feature is that the pipe shaft of smoke pipe is provided with the tube wall air ducting.

Described tube wall air ducting comprises that the position of air-guiding hole on the pipe shaft that is distributed on smoke pipe and corresponding air-guiding hole is arranged on the wind-guiding tongue piece of the pipe shaft inside of smoke pipe.

Described air-guiding hole is D shape or rectangle; Wind-guiding tongue piece shape is consistent with the shape of air-guiding hole, and the direction of itself and air-out tilts, and angle [alpha] is the 20-60 degree.

Described air-guiding hole and wind-guiding tongue piece are by integrally formed to the pipe shaft punching press of smoke pipe.

The internal vertical of the tail end of described smoke pipe is provided with the rotating shaft bracing frame, and it is positioned at the top of smoke pipe, is horizontally arranged with rotating shaft on the rotating shaft bracing frame, and the upper end of valve block is rotatably connected in the rotating shaft, and the position of corresponding valve block is provided with catch in the smoke pipe wall.

Described valve block is fan-shaped or mushroom-shaped.

The utility model is provided with the valve block of anti-down draught by the tail end inside at smoke pipe, its wind-fall that can effectively prevent the external world is irritated to water heater inside, and air-guiding hole and wind-guiding tongue piece be set on the pipe shaft of smoke pipe, when the wind of smoke pipe around running into come, wind-guiding tongue piece on the air-guiding hole can change the wind direction of the wind that enters smoke pipe, wind is discharged outside the smoke pipe smoothly, can not allow smoke pipe be blown to distortion even damage by high wind even high wind attacks.
