Description

Back-flow direct water heating unit

The utility model is a kind of water heater, and it relates to a kind of directly-heating type water heater, specially refers to a kind of backflow directly-heating type water heater.It can be placed on gas stove and the coal stove directly heats and generation hot water.

Along with improving constantly of current living standards of the people, people wish progressively to improve the living facilities of oneself, have a bath as daily, also are the somethings during people live.For sanitation and hygiene, family with good conditionsi has bought instant shower heater, has increased sanitary installation.The water heater of supplying on the present city field boundary, divide two big classes substantially: a class is the electrothermal water heater, because this class water heater power consumption is big, dangerous, therefore, uses and popularizes.Another kind of is gas heater, and the advantage of this class water heater is that the hot merit energy is big, heat transfer is fast, the heat production water yield is big, be more welcome at present a kind of water heater, but also there is following shortcoming in this class water heater: (1) complex structure.Except that the Inlet and outlet water joint, also be provided with burner, heat exchanger aqueous vapor control device etc. partly; Need change the burner pipeline when (2) installing, must after relevant department (Gas Company) application permission, can install and use.And, need the professional to implement to the security requirement strictness is installed.This just limits its application greatly; (3) price is more expensive.The family of general income, once investment is had any problem.

The purpose of this utility model just is to overcome the shortcoming of prior art, provides a kind of simple in structure, installs and need not change gas pipeline, backflow directly-heating type water heater that price is lower.

The purpose of this utility model is achieved in that and comprises the Inlet and outlet water joint, it is characterized in that: be provided with the heating courage and at the pyrosphere that protects of its periphery; Heating courage and protect pyrosphere and be connected with the Inlet and outlet water joint utilizes gas stove and coal stove directly to heat generation hot water.

Further set forth concrete enforcement of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the scheme of installation that two polyphones of the utility model use.

Referring to Fig. 1, the utility model is provided with water supply connector 1, lid 2, water out adapter 4, it is characterized in that: also be provided with the heating courage that is made of outer courage 5 and inner bag 6 and at the stove fire circle 3 of periphery; Heating courage and stove fire circle 3 are connected with water supply connector 1 and water out adapter 4; Because they all are double-deckers, its inside is equipped with backflow track 7, and to increase heat exchange, it is balanced that water is heated.The utility model can be used the stainless steel aluminum alloy thin plate

Use of the present utility model heating principle is as follows: with the Inlet and outlet water joint with after running water pipe and outlet pipe link to each other, be placed on gas stove or the coal stove and heat, after cold water enters water heater, flow into the heating courage respectively and protect pyrosphere and be heated, because of it is provided with the backflow track, water makes heating more even through the backflow track, and flowing out at last is hot water.The effect of protecting pyrosphere is to prevent that heat scatters and disappears, and makes full use of peripheral heat and produces hot water.Evidence, it can save energy about 30% than common kettle and aluminum pot.Two seasons in the Winter-Spring, because of temperature low, available two polyphone heating, as shown in Figure 2: the water out adapter 4 of two water heaters is connected, at this moment the Inlet and outlet water joint 1 of two water heaters, one still links to each other with running water pipe for water supply connector is used as, another becomes water out adapter, as linking to each other with outlet pipe, make two water heaters be concatenated into a water heater, utilize two burners of gas stove to heat simultaneously, or heat simultaneously with two coal stoves, water temperature can reach about 40 ℃, and 5～6 liters/minute of flows satisfy instructions for use substantially.

In sum, the utility model compared with prior art has following advantages: (1) is simple in structure, easy to manufacture, easy to use; (2) install, dismounting is all very convenient, need not change gas pipeline, therefore, uses to need not the application license to relevant department, be easy to promote; (3) price is lower, and general family all can bear, and also can utilize briquet stove heating, and the town-dweller-rural-family that also can satisfy no combustion gas uses.

Claims (2)

1, a kind of backflow directly-heating type water heater comprises the Inlet and outlet water joint, it is characterized in that: be provided with the heating courage and at the pyrosphere that protects of its periphery: heating courage and protect pyrosphere and be connected with the Inlet and outlet water joint.

2, water heater as claimed in claim 1 is characterized in that: the heating courage all is double-deckers with protecting pyrosphere, and its inside is provided with the backflow track.
