Description

A kind of Firewood water heater

Technical field

The present invention relates to a kind of water heater that heat-generating device is arranged, specifically a kind of Firewood water heater.

Background technology

Along with rapid economy development, China town dweller has mostly used water heater, by water heater cold water is heated, and is used for washing one's face, has a bath and washes clothes etc.At present, water heater generally has solar water heater, electric heater, liquefied gas heating-water and coal burning water heater, and these water heaters not only price and in use also can produce a large amount of expenses than higher, such as, electric heater and liquefied gas heating-water can produce the electricity charge and gas expense.And China is a large agricultural country, it also is country in the most development in the world, energy resource structure is mainly still based on bavin, grass, coal, account for the restriction of the vast rural area people of national population 70% because of conditions such as fuel, economy, geographical environments, can't use present electricity, gas, solar water heater bathing on the market, sanitary condition is poor, and quality of life is low, influences the healthy of people.Therefore, be directed to the short of electricity of vast rural area, weak breath, the situation of capacity firewood is arranged again simultaneously, need a kind of special firewood-burning water heater of design.In order to address the above problem, that Chinese patent discloses is a kind of " the perpendicular multitube fast heating type Firewood water heater of putting " (Granted publication number: CN 201265949Y), perpendicular put multitube fast heating type Firewood water heater and comprise combustion furnace, preheating water tank and be contained in heat exchanger in the preheating water tank, the upper end open of combustion furnace, be connected with the lower end of described heat exchanger, described preheating water tank is connected with cold water inlet, described heat exchanger comprises the combustion chamber of bottom, the exhaust collection chamber on top and be installed in the combustion chamber and the exhaust collection chamber between the post bake tube, be distributed with heat pipe in this post bake tube periphery; The lower ending opening of described combustion chamber communicates with the inner chamber of described combustion furnace, the upper end open of described exhaust collection chamber communicates with the external world through smoke exhaust pipe, this exhaust collection chamber is communicated with through described heat pipe with described combustion chamber, the upper and lower side opening of described post bake tube is respectively by the base plate of described exhaust collection chamber and the top board sealing of described combustion chamber, between this post bake tube and described heat pipe, be provided with the post bake water inlet pipe, the lower end mouth of pipe of this post bake water inlet pipe is installed in the bottom of described post bake tube, the upper end mouth of pipe of this post bake water inlet pipe is installed in the outer wall of described exhaust collection chamber, with the relatively described base plate of described post bake tube on be provided with the post bake outlet pipe, hot water storgae on this post bake outlet pipe passes described exhaust collection chamber and is located at described exhaust collection chamber outer wall communicates, and this hot water storgae is connected with the hot water outlet pipe.Though this water heater has solved the problem of the practical water heater in rural area, but still exist following deficiency: 1, water carries out preheating in from the water inlet pipe to preheating water tank under the normal condition, enter the post bake tube after the preheating and carry out post bake, but, because preheating water tank's area is bigger, and water inlet pipe and the import of post bake tube are all smaller, cold water can not be pushed to the hot water among the preheating water tank in the post bake tube and carry out post bake, cause the preheating water tank to form the slough, do not have the effect of preheating cold water, cause the hot water efficient of Firewood water heater not high; 2, because the mode of natural air inlet is adopted in the combustion chamber, cause bavin not burn fully, efficiency of combustion is lower.

Summary of the invention

The technical problem to be solved in the present invention is to overcome above defective, provides a kind of heat utilization efficiency height, heating soon, and fuel combustion is Firewood water heater more fully.

In order to solve the problems of the technologies described above, the invention provides a kind of Firewood water heater, comprise chimney, storage tank, preheat exchanger, burner, wherein preheat exchanger is positioned at water tank, its outlet communicates with the external world by chimney, the bottom of storage tank is provided with Connection Block, the upper end of burner is stretched in this Connection Block, and be fixed on the Connection Block, the bottom sidewall of burner is provided with air inlet, described preheat exchanger is the wall hollow structure, its lower end is provided with water inlet pipe, its wall is provided with the fin of heat transfer and baffling, also is provided with the spiral heat transfer water pipe that distributes along its passage in the preheat exchanger pipe, and the water inlet of this spiral heat transfer water pipe links to each other with the delivery port that is arranged on the preheat exchanger upper end; The delivery port of described spiral heat transfer water pipe is connected with water knockout drum, also connects tap and storage tank on this water knockout drum; Described burner is made of inner bag and shell, and inner bag is connected with the import of described heat exchanger, and the inner bag frame props up in the enclosure, and inner bag is provided with fresh air inlet; Described storage tank sidewall is provided with the water wheels fan that is driven by current, and this fan and described main air port are corresponding.

Further, in order better burner to be fixed on the water tank, to be distributed with two symmetrically on the outer wall of described burner upper end and to hang pin, described Connection Block is provided with hanging groove corresponding with it.

Further, in order to improve the thermal efficiency, increase heat transfer area, described preheat exchanger is the back-shaped channel design of import and export at same end.

Further, in order better to understand the combustion case in the burner, described Connection Block is provided with the peep hole that is used for observing the intensity of a fire.

Further, in order better to understand the water yield information in the water heater storage tank, also be provided with the linker of observing water level on the described storage tank.

Further, for the ease of replenishing the air of capacity in the combustion process, described inner bag is cancellated inner bag.

Further, in order to prevent hot water and the air exchange heat in the storage tank, cause temperature to reduce, the outer wall of described storage tank is provided with the foam of insulation.

Cold water is earlier through the water wheels fan, when rotating, drive fan reduces hydraulic pressure to suitable level, and then through preheat exchanger, tentatively heated, enter spiral heat transfer water pipe afterwards again and carry out the heating of secondary, after the hot water process spiral heat transfer water pipe post bake, can normally use, unnecessary hot water can flow in the storage tank standby through water knockout drum.

Adopt the Firewood water heater of technique scheme,, make heat transfer area bigger, improved the efficient of heat utilization owing to adopted the preheat exchanger of back-shaped structure; Because the wall of preheat exchanger is provided with for conducting heat and the fin of baffling, has not only increased the area of heat transfer, and deflection plate is no longer to produce the slough in the preheat exchanger, improved the result of use of preheat exchanger greatly; Simultaneously because water heater is provided with the water wheels fan that is driven by current,, make the burning of bavin more abundant for the combustion process of bavin provides a large amount of air.
