Abstract

The utility model relates to a water heater wind-proof exhausting device, which is characterized in that the inner cap of the top of a water heater is bent to front upwards and extending out of an opening in the upper section of the face side of the water heater shell; the cover of the open end of the inner cap is provided with a forwardly protruding wind-guard cap, the upper and the lower sides of the cover is in a through state, and the inner of the cover is provided with the vertical standing partition board of an opening corresponding to the open end of the opening of the inner cap; the structure of the utility model can expel exhaust heat air out of a housing, and avoid external strong wind being blown into a combustion chamber.

Description

Water heater wind-proof exhausting device

The utility model relates to the windproof exhaust apparatus of a kind of water heater.

Gas water heater is the heat that utilizes burning coal gas to produce, and heats the cold water in the circulation line into hot water through over-heat-exchanger; Burning hot gas or waste gas that coal gas produced are up discharged from the interior cap at heat exchanger top; Water heater generally all is installed in outdoor, owing to do not have wind-proof device in the interior cap, in case run into high wind, high wind will directly be blown in the combustion chamber from interior cap openend from top to bottom, so that coal gas can not completing combustion, sometimes even can put out flame; In addition, this high wind that is blown into from top to bottom also can influence hot gas or exhaust gas discharging.

Above-mentioned defective in view of the exhaust apparatus that has water heater, the purpose of this utility model is to provide a kind of windproof exhaust apparatus that is used for water heater, it can successfully discharge housing with waste gas hot gas, and can avoid extraneous high wind directly to be blown into the combustion chamber, thereby reaches good windproof exhaust purpose.

To achieve these goals, the windproof exhaust apparatus of the utility model mainly by protrude in epimere place, water heater housing front to the front upper place crooked and extend horizontally away the interior cap of housing and cooperate with it be located at the storm shutter of the giving prominence to epimere of housing front outside forward and the dividing plate between storm shutter and the housing is formed; This structure can successfully be discharged housing with waste hot gas, and can avoid extraneous high wind directly to be blown into the combustion chamber.

Windproof exhaust apparatus of the present utility model is compared with exhaust apparatus in the past, owing to adopted interior cap is drawn the outer form of housing and added storm shutter at interior cap openend, thereby guaranteed that waste hot gas can successfully discharge housing and can not be subjected to the influence of extraneous high wind again, water heater can more effectively be worked.

About above-mentioned purpose of the present utility model and design, will be described in detail as follows in conjunction with a possible embodiments conjunction with figs..

Fig. 1: the stereogram of an embodiment of windproof exhaust apparatus of the present utility model;

Fig. 2: three-dimensional exploded view embodiment illustrated in fig. 1;

Fig. 3: assembled sectional view embodiment illustrated in fig. 1.

See also Fig. 1, water heater housing 1 left and right sides of present embodiment and dorsal part lower semisection are provided with the square air admission hole 11 of many group leaders, those pores are to form after going out the corresponding deflector that bends below interior on the housing, with so that outside air is gone into housing 1 inside by these orifice flows.

Consult Fig. 2, Fig. 3.The interior cap that heat exchanger top commonly used is nested with is the housing that passes vertically upward, therefore can not avoid extraneous high wind directly from interior cap openend through under be blown into the combustion chamber, and then influence the flame situation.Present embodiment is mainly with the interior cap 2 at heat exchanger top toward front upper places crooked 90 °, horizontal-extending again, and pass the horizontal oblong openings at epimere place, water heater housing 1 front, and the opening of interior cap be consistent with it rectangle, thus the formation discharge duct.This water heater housing 1 front upper semisection is covered with an outstanding storm shutter 3 forward, so that interior cap 2 openends are contained in wherein, this storm shutter 3 adopts metallic plate to be bent into, its front side wall 31 is separated by parallel with water heater housing 1 face wall, and form grab on left and right sides sidewall 32 trailing edges, go into water heater housing 1 positive going up in the breach relative with buckle with grab, and water heater housing 1 positive with storm shutter 3 front side walls 31 between be provided with the vertical configuration dividing plate 4 that parallels with the housing face wall, this dividing plate 4 also is equipped with bigger horizontal oblong openings at the opposite position with interior cap 2 openends.

When present embodiment used in reality, cap 2 in the waste hot gas that produces during water heater burning coal gas up flow to was discharged forward outside the water heater housing along its 90 degree bending; And when extraneous high wind was flowed through storm shutter 3, the waste hot gas that the internal cap 2 of meeting is discharged produced sucking action, the unlikely exhaust effect that influences.

Present embodiment adopts the structure of storm shutter 3, can prevent extraneous high wind directly be blown in cap 2, avoiding knock down the flame, and storm shutter 3 cooperates the oblong openings of dividing plates 4, the heat in the time of then disperseing exhaust is to avoid water heater 1 surface temperature too high.

Claims

1, the windproof exhaust apparatus of a kind of water heater, it comprises that one is installed on the interior cap at heat exchanger top, it is characterized in that: cap is crooked and extend horizontally away the opening at epimere place, water heater housing front toward the front upper place in described, described in the opening shape of cap consistent with epimere place, described housing front opening shape; Epimere place, housing front opening is covered with the storm shutter of a up/down perforation outward, and the opening of described interior cap is contained in wherein; Be provided with a dividing plate parallel between described storm shutter front side wall and the housing face wall with the housing face wall, described dividing plate mutually internally the cap opening part have one with the consistent opening of interior cap opening shape.

2, windproof exhaust apparatus as claimed in claim 1, it is characterized in that the front side wall of described storm shutter is bent into by metallic plate, its front side wall is parallel with water heater housing face wall, form grab on the wall trailing edge of the left and right sides, to buckle in the breach relative on the housing front with grab.

3, windproof exhaust apparatus as claimed in claim 2 is characterized in that, described interior cap opening is a rectangle.
