Description
Technical field
The utility model relates to a kind of water heater, a kind of water heater in central heating of more specifically saying so.
Background technology
Cold heating of house in winter, having is to adopt the heating installation plate heat interchanger greatly.This heating system though can promote indoor temperature, can not use hot water for the user.In order to use hot water for the user with radiator, the inventor is once with regard to " box-type heating heater using water ", applied for patent, the patent No. is 94240624.9, the technical scheme of this patent disclosure comprises and has water inlet pipe mouth and effluent pipe mouth, and the outer casing shell of sealing, is welded with heat exchanger in the outer casing shell inner chamber.The drawback of this technical scheme is: 1, by the cyclic water jacket that the gap constituted between outer casing shell and the heat exchanger, in the season of not heating,, just water in the cyclic water jacket can be bled off owing to reasons such as maintenances of equipment, cyclic water jacket can produce severe oxidation and corrosion, and shortened the service life of water heater; 2, because outer casing shell and Welding of Heat-exchanger together, make trouble inefficiency.
Summary of the invention
The purpose of this utility model provides a kind of long service life, is convenient to make and supplies the user employed is the water heater in central heating of the highest hot water of water temperature.
In order to realize above-mentioned purpose, this water heater in central heating, the housing that comprises sealing, be fixed with heat exchanger in the inner chamber of housing, the upper end of heat exchanger is communicated with heater inlet pipe, the lower end of heat exchanger is communicated with the heating installation return pipe, it is overhanging that heater inlet pipe and heating installation return pipe pass housing respectively, its design feature is that the intracavity bottom at housing is fixed with and passes that housing is communicated with running water pipe and the cold water inlet pipe of level trend, be fixed with the hot water out pipe that passes the overhanging and level trend of housing at the interior top of chamber of housing, be densely covered with ostium excurrens on the tube wall of cold water inlet pipe, be densely covered with into water aperture on the tube wall of hot water out pipe, heat exchanger is the two-layer pipe that is made of outer tube and interior pipe, gap between outer tube and the interior pipe is a water jacket, water jacket and housing bore seal, be communicated with heater inlet pipe and heating installation return pipe, both ends open is in the housing inner chamber about the interior pipe, reach on its epimere hot water out pipe near.
Above-mentioned ostium excurrens is arranged on the diapire of cold water inlet pipe, and the water inlet aperture is arranged on the roof of hot water out pipe.The aperture of ostium excurrens and water inlet aperture respectively is 6-8mm.
Use for convenience, at the position that the cold water inlet pipe is positioned at outside the housing valve is housed, valve is equipped with at the position outside hot water out pipe is positioned at housing.For guaranteeing safety, the valve on the cold water inlet pipe is a two-way valve.
As the improvement to this water heater in central heating, above-mentioned heat exchanger is two groups at least, and the water jacket between each group is communicated with by tube connector.
During installation, heater inlet pipe and heating installation return pipe are connected on respectively in the corresponding pipeline of heating system, the cold water inlet pipe is communicated with running water pipe.During work, the housing inner chamber is filled with housing inner chamber by the cold water inlet pipe through ostium excurrens by the pressure of running water, and hydraulic pressure equates with the pressure of running water, when the heating system heat supply, the heat energy that heating system is supplied with in the heat exchanger carries out heat exchange by the cold water in water jacket and the housing inner chamber, give cold water with thermal energy transfer, cold water temperature is risen, because the middle hypomere of interior pipe is surrounded by water jacket, thereby the cold water temperature that is arranged in pipe rises the fastest, and along interior pipe rising, accumulate in the top of housing inner chamber after flowing out from the upper end of interior pipe, the low cold water of temperature flows to from the lower end of interior pipe, this process moves in circles, cold water in the housing inner chamber is heated into hot water, and the highest hot water of temperature accumulates in the top of housing inner chamber, the water inlet aperture on the hot water out pipe through being positioned at this position enters hot water out pipe, use for the user, the cold water inlet pipe replenishes running water to the housing inner chamber at any time.Temperature rising along with the water in the housing inner chamber, volume increases, the increase also corresponding to the pressure of housing, for guaranteeing safety, valve on the cold water inlet pipe is selected two-way valve for use, when the user did not use hot water to cause the housing chamber pressure excessive, the water in the housing inner chamber can flow backwards to running water pipe by this two-way valve, realized pressure balance.
By above narration as can be known, water heater in central heating described in the utility model, housing bears tap water pressure, heat exchanger bears the heating installation circulating water pressure, and under these two pressure effects, recirculated water can circulate automatically, using under the situation of hot water running water supply automatically.The beneficial effect of this water heater in central heating is: 1, because interior pipe is filled the water jacket encirclement of heating system hot water, thereby rate of heat exchange is fast, and the user can use hot water at short notice; 2, hot water out pipe is arranged on the highest zone of housing inner chamber water temperature, is the highest hot water of water temperature forever for the employed hot water of user, particularly when bathing, has avoided the sometimes hot and sometimes cold phenomenon of water temperature to take place, for the user brings convenience; 3, because the water jacket and the housing bore seal of heat exchanger, in the season of not heating, even if recirculated water is bled off, heat exchanger and shell inner surface can oxidations and corrosion yet, thereby prolonged the service life of water heater in central heating; 4, because housing and heat exchanger are independent separately, thus easy to manufacture.
