Abstract
The utility model relates to a water-circulation preheating device for water heaters. A winding-back arranged preheating pipeline positioned at the upper part of a heat exchanger is arranged at the upper part of a casing of a combustion chamber of the water heater; a water inlet of the preheating pipeline is connected with a cold water pipe and a water outlet of the preheating pipeline is connected with the water inlet pipe of the heat exchanger; water in the preheating pipeline is directly heated by the afterheat of the heat exchanger, which makes full use of energy; the water with a certain temperature in the preheating pipeline enters the exchanger and then is used for heating quickly for use.
Description
The utility model relates to a kind of water circulation preheating device of water heater.
At present, it is that cold water is absorbed the heat of burning chamber shell outer wall (6) to realize preheating cold water by the preheating pipeline (7) of cold water pipe (4) through being surrounded on burning chamber shell outer wall (6) that water heater makes the method for cold water preheating, the water of preheating enters heating pipe line (2) heating of heat exchanger (1) then, by hot-water line (8) hot water is directed to and uses the place; Find in the practicality that there is following defective in it, during gas-fired in (1) combustion chamber, heating is positioned at the heat exchanger (1) of its top, and housing outer wall (6) temperature around it is not high, so the water preheat poor effect of preheating pipeline (7) lining.(2) unroll and must burn to high temperature fixingly through silver solder welding in the preheating pipeline (7) of burning chamber shell outer wall (6), be easy to generate poisonous fume, influence environmental sanitation, its welding need are by experienced technical operation, otherwise are easy to generate failure welding.
The purpose of this utility model is for overcoming above-mentioned weak point, and the preheating pipeline is located at the heat exchanger top, makes full use of the waste heat of being derived by heat exchanger, and pre-heat effect is good, saves the energy.
The utility model content, the preheating pipeline of the arrangement of unrolling is installed in the top of water heater combustion chamber housing and is positioned on the heat exchanger; The water inlet of preheating pipeline links to each other with cold water pipe, and the delivery port of preheating pipeline links to each other with the water inlet pipe of heat exchanger.
The utility model advantage, owing to the cold water that directly utilizes in the residue hot gas heating preheating pipeline of heat exchanger, pre-heat effect is good, makes full use of the heat that coal gas produces (1).(2) water with uniform temperature that enters heat exchanger by the preheating pipeline can be heated to high temperature quickly, for use.(3) burning chamber shell can be integrally formed, and hot gas is unlikely to leak, and the preheating pipeline can be assembled by special-purpose machinery, and is convenient for assembly, reduces and pollute.
Description of drawings:
Fig. 1 is the utility model stereogram
Fig. 2 is the utility model partial schematic sectional view
Fig. 3 is for now using the water circulation heating pipe line schematic diagram of water heater
Below in conjunction with description of drawings the utility model embodiment, the heat exchanger (1) above the combustion chamber (figure does not show) of water heater is equipped with heating pipe line (2), and the water in heating pipe line (2) is heated through hot-water line (8) and flows out; Be provided with preheating pipeline (51), (52) that multilayer is unrolled and arranged in water heater combustion chamber housing (3) top, this preheating pipeline is positioned on the heat exchanger (1), carry out preheating with direct absorption effectively by the residue hot gas of heat exchanger (1) derivation, make the cold water that flows to by cold water pipe (4) obtain preheating, and then enter the heating pipe line (2) of heat exchanger (1) lining and the effect that reaches a high temperature rapidly through preheating pipeline (51), (52).Burning chamber shell of the present utility model in addition (3) can be one-body molded and be provided with reinforcement (31) to gain in strength.In a word, the utility model has changed the spatial shape of water heater preheating pipeline on the market, directly utilize the waste heat of heat exchanger that cold water is carried out preheating, make full use of the energy, can more promptly cooperate the heating pipe line in the heat exchanger to reach the hot water of higher temperature for use.
Claims (1)
1, a kind of water heater water circulation preheating device that comprises cold water pipe, hot water line, the preheating pipeline arranged of it is characterized in that unrolling is contained in the top of water heater combustion chamber housing and is positioned on the heat exchanger, the water inlet of preheating pipeline links to each other with cold water pipe, and the delivery port of preheating pipeline links to each other with the water inlet pipe of heat exchanger.
