Description

Energy-saving water heater

Technical field

It is the water heater of thermal source that the utility model relates to a kind of heat with domestic burners, kitchen range, especially only utilizes the waste heat energy of stove, kitchen range that the water heater of hot water is provided.

Background technology

At present, known water heater is divided into several: have the high price solar water heater, have with electric energy be thermal source electric heater, gas heater is arranged, the large-sized boiler water heater is arranged, and except that solar water heater, remaining water heater all must expend the substantial contribution and the energy in use in a word.Solar water heater, though the source of not consuming energy, price is more expensive, and much the rural area does not have the running water condition, can't use even buied yet, and just can not use when the moon, snow weather, also has freezing possibility sometimes.Therefore, above-mentioned water heater all has the defective of blemish in an otherwise perfect thing.

Though part uses the family in bavin coal area at the water heater that uses burning bavin coal, but this water heater is that boiler and stove body are made of one, when the bavin coal combustion, boiler is by the hot heat that can directly absorb in a large amount of cooking stoves that transmits, the heating efficiency of cooking stove can reduce greatly, influenced the performance of the normal heating function of cooking stove, and this firewood and coal stove water heater on cooking stove need have under the condition of running water and could use equally.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of energy-saving water heater, and it is simple in structure, and is easy to use, and cost is low, do not influence the heating efficiency of cooking stove, and suitable is the vast cities and towns and the rural area use of fuel with the bavin coal.

Solving the scheme that technical problem of the present utility model adopts is: the cold water water butt is connected to the snakelike spiral tube water inlet end that is provided with in the cooking stove of below with pipeline, the water side is connected to the hot water water butt of height of water level between cold water water butt and cooking stove with pipeline, the blast pipe that hot water water butt top has a root port height to rise more than or equal to the cold water water butt, and hot water water butt bottom connects water appliance.

This water heater adopts snakelike spiral tube to embed in the heat-insulation layer of cooking stove; refractory stove core is enclosed within the metal tube; metal tube is with snakelike spiral tube outward; and snakelike spiral tube and metal tube and the tight contacting structure of refractory stove core three; so both can protect snakelike spiral tube pipe, be convenient for changing combustion chamber simultaneously again.

Be provided with a blowoff valve in the bottom of cold water water butt, the dirt of precipitation at the bottom of can getting rid of easily in use for some time barrel; The cold water water butt is provided with cold valves with the pipeline that snakelike spiral tube is connected, and can control the cold water flow that enters the hot water water butt, and can close when using hot water, and making next time, hot water directly just can enter in the hot water water butt.

When using when lighting a fire in stove or the kitchen range, the heat that its high temperature combustion chamber distributes causes the snakelike heating tube heating of spiraling.Heated water in the copper pipe is delivered in the hot water water butt continually because proportion is lighter.Because copper pipe shared volume in cooking stove is less, the heat of taking away in the unit interval is also less, thereby has fallen at the end influence to cooking stove fire temperature widely, the carrying out smoothly of the stove of having guaranteed to heat up water, cook; In the use of cooking stove, can be heated gradually again in the hot water water butt, need not increase fuel, just can obtain hot water.

The beneficial effects of the utility model are: simple in structure, cheap, and energy savings, the cost of manufacture of heater is significantly less than the heater of other kinds, the also available water that manually adds uses when no running water condition, slowly takes away the useless waste heat of stove or kitchen range in heating process, does not influence the fire temperature

Each label is represented successively among the figure: cold water water butt 1, blowoff valve 2, hot water water butt 3, blast pipe 4, cold water pipe 5, cold water control valve 6, drench shower nozzle 7, hot water control valve 8, cold valves 9, hot-water line 10, coal fire stove handle 11, coal fire stove top case 12, coal filling hole 13, refractory stove core 14, snakelike spiral tube 15, hot water outlet 16, cold water inlet 17, metal outer wall 18, heat-insulation layer 19, metal inner surface 20, coal fire stove handle mouth hanging 21, coal fire body of heater 22, fire bars 23, coal fire furnace bottom heat-insulation layer 24, coal fire furnace ventilation mouth 25, coal fire furnace bottom sealant 26, chimney 27, the kitchen range top 28, chimney import 29, kitchen range return air ditch 30, kitchen range door 31, stove 32, ventilation ash disposal mouth 33 at the bottom of the kitchen range.。

The specific embodiment

Referring to the coal fire stove formula water heater shown in Fig. 1,2, cold water inlet 17 1 ends of heated snakelike spiral tube 15 are connected with the cold valves 9 of the control water yield, connect cold water water butt 1 by cold water pipe 5 again, the other end hot water outlet 16 of snakelike spiral tube 15 connects hot-water line 10, connects hot water water butt 3 again.Refractory stove core 14 is movable, is enclosed within the metal tube 20, and snakelike spiral tube 15 is enclosed within outside the metal tube 20 and the three closely contacts, and embeds in the heat-insulation layer 19 of body of heater again, when refractory stove core 14 usefulness are damaged for a long time, can extract replacing easily out.When using hot water,, cold water control valve 6 or hot water control valve 8 can be opened, satisfied suitable warm water can be obtained if temperature is improper.

Referring to the firewood water heater on cooking stove shown in Fig. 3,4, owing to before the kitchen range kitchen range door 31 is arranged, therefore, refractory stove core 14 adopts cast iron to make horse-hof shape, 14 one-tenth openings of snakelike spiral tube 15 and refractory stove core surround the grafting of shape cover and touch, and all the other structures and connection are identical with last one routine coal fire stove formula water heater.

Referring to combined type stove, water heater on cooking stove shown in Figure 5, under many circumstances, the family that has is using stove and kitchen range simultaneously, at this moment just can be together in parallel by the water heater of pipeline with stove and kitchen range.Be the cold water pipe 5 and the hot-water line 10 of cold water water butt 1 and hot water water butt 3, be communicated with simultaneously with snakelike spiral tube 15 in stove and the water chestnut kitchen range by three-way pipe.If when adopting the firewood kitchen range, close the cold valves 9 of coal fire stove water heater, open the cold valves 9 of firewood water heater on cooking stove simultaneously, thereby the water circulation path of coal fire stove water heater is cut off; If when adopting the coal fire stove, then close the cold valves 9 of the firewood water heater on cooking stove control water yield, open coal fire stove water heater cold valves 9 simultaneously, remaining structure be connected identical with above independent coal fire stove formula water heater example.
