Abstract
The utility model discloses an anti-downdraft device of a gas water heater, comprising a smoke pipe connected with a flue of the water heater and a plugging cover arranged on the smoke pipe, wherein a sleeve is connected between a smoke inlet pipe and a smoke outlet pipe; one end of the smoke inlet pipe, positioned at one end in the sleeve, is an inclined surface; the plugging cover is rotatablely connected on the inclined surface; and the bottom end of the sleeve is provided with a condensate water outlet joint. The anti-downdraft device not only can prevent downdraft of cold wind, has simple structure, is not limited for the installing position, not only can be installed vertically, but also can be installed horizontally, also has less wind resistance and effectively solves the hidden danger caused by condensate water.
Description
Technical field
The utility model relates to the gas heater technical field, relates to a kind of anti-down wind apparatus of gas heater smoke exhaust pipe in particular.
Background technology
At present, it is forced-ventilated that the fume exhausting type of gas heater mostly is greatly, needs to be discharged to outdoor by the flue gas of smoke exhaust pipe after fuel gas buring, when weather cold, when outdoor wind-force was big, cold wind can pour in down a chimney by smoke exhaust pipe and enters in the gas heater, causes heat exchanger (water tank) bursting by freezing under the holding state.Therefore, most of gas heater all is provided with anti-down wind apparatus, as application number is CN200820048243.2, CN200820048244.7, the utility model patent of CN200920051031.4 etc., these patents are all about anti-down wind apparatus, though they can prevent that cold wind from pouring in down a chimney, but its installation site limited (can only erect installation), windage is bigger, and there is not a condensate processor, when outdoor temperature is low, the flue gas of the discharge condensed water that can condense at anti-down wind apparatus place, these condensed waters have been assembled many will pour in down a chimney into main frame inside, corrode parts or cause short circuit, have a strong impact on the life-span and the use of water heater.
Summary of the invention
The utility model is exactly the anti-down wind apparatus of a kind of gas heater that provides in order to solve above-mentioned technical deficiency, can not only prevent cold wind pour in down a chimney, simple in structure, the installation site is unrestricted, can erect installation, but level is installed again, and windage is less, and efficiently solves the hidden danger that condensed water brings.
The utility model is to adopt following technical scheme to realize above-mentioned purpose: the anti-down wind apparatus of a kind of gas heater, include the smoke pipe that is connected with water heater flue and be located at blanking cover on the smoke pipe, it is characterized in that: this smoke pipe includes smoke-intake pipe and pipe, between smoke-intake pipe and pipe, be connected with a sleeve pipe, and the end of smoke-intake pipe in sleeve pipe is an inclined-plane, blanking cover is rotatably connected on this inclined-plane, is provided with the condensed water water out adapter at casing shoe.
As further specifying of such scheme, described inclined-plane is for along the inclined-plane that the flow of flue gas direction is provided with from high to low, and this inclined-plane and horizontal plane angle are 5～85 °.
Described blanking cover is a planar structure of tabular or hemisphere that cooperates with the port inclined-plane, and its area is more than or equal to port inclined-plane area.
Described sleeve pipe is a tubular structure, and this casing diameter is greater than the diameter of smoke pipe.
Described being rotatably connected is hinged or bearing pin connection.
The beneficial effect that the utility model adopts above technical scheme to reach is:
1. the utility model is provided with an inclined-plane on pipe, a blanking cover has been rotatably connected on the inclined-plane, when water heater working, the flue gas of forced-ventilated can back down blanking cover and discharge flue gas, when outdoor wind-force is big, if cold wind pours in down a chimney the outlet that blanking cover then can be blocked smoke-intake pipe, prevent that cold wind from pouring in down a chimney into water heater inside.
2. the utility model is provided with a sleeve pipe between smoke-intake pipe and pipe, be provided with the condensed water water out adapter at casing shoe, when the flue gas of discharging is met cold behind the condensed water that freeze-outs on the blanking cover, converged in the sleeve pipe by gravity, flow away from the condensed water water out adapter then, pour in down a chimney into water heater inside to prevent condensed water.
Description of drawings
Figure 1 shows that structural representation of the present utility model.
Description of reference numerals: 1. smoke-intake pipe, 2. pipe, 3. blanking cover, 4. sleeve pipe, 5. turning cylinder, 6. condensed water water out adapter.
