Abstract

The utility model relates to a water heater composed of a base, a water complementing tank, a warm water tank, a high temperature water tank, a flue pipe, a combustion chamber, etc., wherein the combustion chamber is surrounded by the warm water tank and the high temperature water tank. The combustion chamber is divided into an upper layer, a middle layer and a lower layer, and the upper layer and the lower layer are provided with grates used for combustion. The utility model has the advantages of thorough combustion, less pollution and stable fire power. Besides, the utility model can rapidly and continuously supply boiling water in time.

Description

A kind of water heater

The utility model relates to a kind of combustion furnace, especially is fit to the drinking water boiler of hot-water supply.

At present, water heater very is widely used for units such as residential block, office, group and supplies water, and it has, and cost is low, operating cost is low, occupation of land is little, and the flexibility height is subjected to user's welcome.Chinese patent ZL91233143, introduce a kind of Natural Circulation heating and used a day pressure water heater more, it is by base, boiler, the broken-line type smoke pipe, compositions such as combustion chamber, it is characterized in that, lower hot water tank connects, last boiler top is equipped with heating hot water outlet pipe interface, the lower hot water tank bottom is equipped with heating hot water return pipe interface, adopt on the tetrahedron of two different base angles tetragonous cone tables compositions the combustion chamber, lower combustion chamber's structure, is the variable section structure flue from upper combustion chamber's shape pump mouth of twitching one's mouth to the sweptback first section flue that make progress, and second section flue near normal ground also adopts variable section structure.The combustion furnace of this structure, incomplete combustion has black smoke to produce, the utilization rate of fuel is not high, simultaneously, when coal, influence firepower, can not satisfy the needs of supplying boiling water in time, also owing to incomplete combustion, the flue tube in exit stops up for avoiding, and generally adopts bigbore pipe, so just reduced the preheating area, utilization rate of waste heat is low.

The utility model is to overcome above-mentioned deficiency, provides a kind of energy boiling water without interruption, and burning is complete, the water heater of stable fire.

The utility model can be realized like this: a kind of water heater, form by base, water supply tank, reservoir, high-temperature water tank, flue tube, combustion chamber etc., water supply tank and reservoir, reservoir is communicated with pipeline with high-temperature water tank, flue tube feeds in the water supply tank, the combustion chamber is surrounded by reservoir and high-temperature water tank, it is characterized in that branch upper, middle and lower, combustion chamber layer, every layer all has fire door, upper and lower layer is provided with fire bars, the intermediate layer communicates with floss hole, and high-temperature water tank and reservoir are respectively equipped with standpipe and communicate, and the other end of the two standpipes opening that crosses is gone into water supply tank.The utility model is when work, the upper strata oven door opening adds coal combustion, and the water in reservoir and the high-temperature water tank is heated, in the combustion process, the coal that does not have after-flame to fall burns away in lower floor, and the middle level communicates as the air channel with floss hole, can deashing, when burning like this, day-coal burns downwards, and lower floor's coal is burning upwards, and firepower is powerful; Simultaneously, when the coal of upper strata,, or not do not keep stable fire because of the coal cooling influences firepower owing to be downward burning.Standpipe can make the steam that produces in reservoir and the high-temperature water tank be introduced into water supply tank.

The fire bars of the fire bars of the utility model combustion chamber, particularly upper strata can be with the every pipe of stove, and fire bar tube communicates with high-temperature water tank.Owing to water is arranged in the fire bar tube, can be fully, the fast Absorption heat, can prevent fire bars because of the high temperature deformation bending simultaneously, raising service life.

The utility model can burn well, and flue dust is few, is difficult for stopping up flue tube, therefore can be provided with many in water supply tank, general 2-9 root flue tube, and the area of dissipation of increase flue tube makes full use of waste heat, the preheating that the water in the water supply tank is obtained.

In order to make the flame in the combustion chamber more even, steady, 2 flues can be set in the middle level, combustion chamber be in charge of, this flue is in charge of the feeding high-temperature water tank.Because the existence be in charge of of this flue, can change the distribution of wind in the combustion chamber or air, make burning more even.

The waste gas of being discharged during the utility model work is few, and various coals are all applicable.Stable fire during burning, thermal efficiency height can in time quick boiling water without interruption, has good economy, society and environmental benefit.

Below in conjunction with accompanying drawing, further specify the utility model:

Water heater is by base (1), water supply tank (2), reservoir (3), high-temperature water tank (4), flue tube (5), combustion chamber compositions such as (6), water supply tank (2) is connected on the running water pipe, can control its water level by ball float, realize automatic water supplement, water supply tank (2) and reservoir (3), reservoir (3) and high-temperature water tank (4) pipeline (21 that has check valve, 22) be communicated with, flue tube (5) feeds in the water supply tank (2), combustion chamber (6) is by reservoir (3), high-temperature water tank (4) surrounds, on the combustion chamber is divided, in, lower floor, upper strata (61), middle level (62), all there is fire door (91 in lower floor (63), 92,93), upper strata (61) is provided with fire bar tube (10), lower floor (63) is provided with fire bars (11), fire bar tube (10) communicates with high-temperature water tank (4), middle level (62) communicates with floss hole (52), middle level (62) also is provided with two flues and is in charge of (51), this flue tube (5) is provided with 4, and high-temperature water tank (4) and reservoir (3) are respectively equipped with standpipe (23,24) communicate with it, two standpipes (23,24) the other end opening that crosses is gone into water supply tank (2).During the utility model work, cold water enters water supply tank (2) and introduces reservoir (3) by pipeline (21) after by flue tube (5) preheating, continue to heat, introduce high-temperature water tank (4) by pipeline (22) again, water in water in the fire bar tube (10) and the high-temperature water tank (4) continues to heat, can be boiled at short notice.Two standpipes (23,24) that communicate with high-temperature water tank (4) and reservoir (3) can be introduced water supply tank (2) with the vapours of its generation, also can carry out preheating to water supply tank.
