Abstract

The utility model provides an efficient fast water heater. The efficient fast water heater improves the traditional structure design that a circulation water pipe surrounded by a furnace core is used for heating, and adopts a new structure design that the flue discharge pipe passing through the inner water tank is used for heating and a reverse flue discharge pipe passing through the outer water tank is used for the further use of the waste heat. The utility model has the advantages of simple structure, easy processing, low cost, high heat efficiency, and obvious energy saving effect. The efficient fast water heater can be free from the affection of the water quality and be free from the limitation of the kind of the heating source, and can be widely used for bath by urban and rural residents.

Description

Efficient fast water heater

The utility model relates to a kind of water heater, particularly a kind of efficient fast water heater.

The water heater of Xiao Shouing in the market, part more or less all comes with some shortcomings.As solar water heater, though no fuel expends in the use, can only use in sun-drenched summer, be subjected to seasonal restriction too strong; The electrical heating water heater is clean, quick, but power consumption is many, the expense cost height; The gas heater complex structure, processing difficulties, the price height, and can only adopt petroleum gas, liquefied gas and coal gas to make fuel, and the thermal efficiency is lower, and fuel expends height, can not enter huge numbers of families.

For addressing these problems, CN85202310 discloses a kind of efficient bath fast water heater, and this water heater mainly is made up of preheating chamber, helix tube and main heating clamber.In preheating chamber, be provided with aqueduct; Helix tube is connected preheating chamber and main heating clamber, forms a water passage circulation system, thereby realizes the cold water multiple gradual is heated up, heats repeatedly, reaches continuous input cold water, constantly exports the purpose of hot water, raising heat exchange efficiency.The be not heated restriction of source category of this water heater, various coal stoves, gas burner, liquefaction vapour, firewood etc. can be made thermal source.Can realize bogey, high efficiency.But this water heater internal structure is complicated, processing is difficult, and the thermal efficiency is not really high.

The purpose of this utility model is to provide a kind of simple in structure, with low cost, fast water heater that the thermal efficiency is high.

The purpose of this utility model is achieved in that efficient fast water heater comprises shell, inner water tank, outer water tank, kuppe, flue and burner cover, and the flue comb passes the upper and lower surface of inner water tank, and the inverted flue comb passes the upper and lower surface of outer water tank.

Kuppe is positioned at above the inside and outside water tank and with the outer water tank outer surface and engages, and shell, outer water tank outer surface and kuppe constitute flue jointly.Outer casing underpart engages with the inner water tank bottom, and the inner water tank lower external face links to each other with the burner cover, has air vent on the burner cover.Outer water tank was connected with inner water tank by superposed communicating pipe.Water inlet is positioned at the outer water tank bottom, and delivery port is positioned at inner water tank top and passes kuppe and shell.

The utility model is owing to adopted inner water tank to surround the flue comb, and outer water tank surrounds this heating arrangement of inverted flue comb, adopts recirculated water, and thermograde is big, and endotherm area is big, thermal efficiency height; Because the flue gas of process inner water tank flue comb passes through the inverted flue comb in the outer water tank again under the kuppe effect, waste heat is able to further utilization, and the thermal efficiency further improves (up to more than 90%), and energy-saving effect is (energy consumption reduces by 2/3) obviously; Because this water heater inside does not almost have pipeline to connect, and can not stop up because of fouling, and is not high to water quality requirement; All can utilize its thermal source highly versatile as long as can produce the fuel of flame simultaneously; Because this utility model is simple in structure, easy to process, cost is lower, is convenient to promote, and is easy to be accepted employing by vast urban and rural residents.

Below in conjunction with embodiment the utility model is further described:

Embodiment 1: Fig. 1 and Fig. 2 are the structural representation of the efficient fast water heater of column type.

This water heater is made up of shell 1, inner water tank 2, outer water tank 3, kuppe 9, flue 16 and burner cover 10.Flue comb 4 passes inner water tank 2 upper surfaces 6 and lower surface 7, and inverted flue comb 5 passes outer water tank 3 upper surfaces 6 and lower surface 8.Inner water tank 2, outer water tank 3 were communicated with by superposed communicating pipe 13.Kuppe 9 is positioned at inner water tank 2 and engages above the outer water tank 3 and with outer water tank 3 outer surfaces 17, shell 1, outer water tank outer surface 17 and kuppe 9 common formation flues 16.Outer casing underpart and burner cover top engage with inner water tank bottom outer rim, and shell upper is established flue outlet 15, has air vent 11 on burner cover 10.Water inlet 12 passes shell 1 and outer water tank is communicated with, and delivery port 14 passes inner water tank upper surface 6, kuppe 9 and shell 1.

During use, this water heater is placed on the kitchen range, burner cover 10 is over against the kitchen range mouth, and water inlet 12 connects water tap, and cold water enters outer water tank 3 preheatings from water inlet 12, and by entering inner water tank 2 heating communicating pipe 13, hot water is drawn by delivery port 14 after outer water tank almost fills with.High-temperature flue gas is behind flue comb 4, and most of heat is absorbed by water in the inner water tank 2, and through inverted flue comb 5, waste heat is further absorbed by cold water in the outer water tank 3 low-temperature flue gas under kuppe 9 effects, thereby the thermal efficiency increases substantially, and energy-saving effect is obvious.

Embodiment 2: Fig. 3 and Fig. 4 are the efficient fast water heater structural representation of square.Each label representative parts is with embodiment 1 among the figure, and each parts connected mode and water heater working mode are with embodiment 1.
