The communicating pipe communicates the heating kettle with the thermal-insulating water barrel to form a water circulation loop, and the end of the communicating pipe which is inserted into the water barrel is provided with a one-way valve. The utility model has obvious energy saving, simple structure, low cost, reliable performance, convenient use, etc. The utility model solves the bath problem of ordinary residents.

Description

Domestic coal stove exhaust-heat energy-storing water heater

The utility model is a kind of domestic briquet stove waste heat energy storage water heater.

Along with the development of home appliance, gas heater, EWH came out one after another in recent years, had solved the problem of having a bath for a part of city dweller.But these water heaters are owing to cost an arm and a leg, and most of residents hold economically and dare not accept.Therefore people's active development utilizes the heat energy of coal stove to design various hot water apparatus, what have has applied for patent, it has energy-conservation, inexpensive characteristics, but because the structure imperfection that has, the complex structure that has, have utilize pressure cooker inadequately safety or the like, be not developed to bulk article and put on market.

The purpose of this utility model provides a kind of energy-conservation, inexpensive, simple in structure, safe and reliable domestic briquet stove waste heat energy storage water heater.

The utility model is achieved in that the family expenses energy storage water heater has adopted novel mode of heating and hot and cold water to flow to control and designed, it is by the special heated sealed kettle that hot water is concentrated cover that has, communicating pipe and insulation water butt are formed, add between hot-water bottle and the water butt to be communicated with communicating pipe, the end that communicating pipe is inserted water butt is equipped with a check valve, with the flow direction of control water, thereby constitute domestic briquet stove waste heat energy storage water heater.

These family expenses coal stove residue heat water heater is applicable to that the family that makes fuel with honeycomb briquette uses, and still have an appointment 80% family of present domestic urban and rural residents uses coal stove.It has energy-conservation obvious, simple in structure, with low cost, characteristics such as performance is safe and reliable.Easy to use, not only for the ordinarily resident solves the problem of having a bath, and hot water supply function at ordinary times, at one stroke two.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a domestic briquet stove waste heat energy storage water heater structure chart

With reference to Fig. 1, domestic briquet stove waste heat energy storage water heater concentrates the heated sealed kettle 1 of cover 2, communicating pipe 3,6 and insulation water butt to form by the special hot water that has.Adding hot-water bottle 1 is a special sealing kettle, the bottom is a curved surface, to increase heating surface area, the curved surface top is a highest temperature zone in the kettle, hot water in the kettle is concentrated 2 pairs of director surface central authorities of cover, be fixed on sealing and be communicated with on the joint 7,, and control it along pipeline 3 outflows in order to the hot water that heated once more in the concentrated kettle.Hot water concentrates the following peripheral of cover 2 that one or more breach or through hole are arranged, so that the hot water of lower temperature flows into heating rapidly once more in the cover in the kettle.A water inlet pipe 8 and overflow pipe 9 are equipped with in insulation water butt 4 tops, with the water level in the control insulation water butt.Add between hot-water bottle 1 and the water butt 4 with communicating pipe 3,6 are communicated with, the end that communicating pipe 3 is inserted water butt has a check valve 5, the flow direction with control water, thereby formed the closed circuit of hot water, the water that adds in the hot-water bottle absorbs heat energy continuously from the coal stove waste heat, the hot water that obtains higher-energy is through constantly entering insulation water butt 4 communicating pipe 3, and the hot water that temperature is lower in the insulation water butt does not flow into cracked ends communicating pipes 6 and adds hot-water bottle and replenish, so circulation, waste heat in the coal stove constantly enters the insulation water butt by hot water, make wherein that the hot water temperature raises gradually, use for shower.During not shower, the hot water in communicating pipe 3 enters insulation water butt 4 by check valve 5.During shower, check valve 5 is closed under the differential water pressures effect automatically, and hot water flows directly into shower room in communicating pipe 3.No matter whether carry out shower, add the hot water that flows out from pipeline 3 in the hot-water bottle and replenish through flowing into kettle 1 communicating pipe 6 by the hot water the insulation water butt.

Claims (3)

1, a kind of domestic briquet stove waste heat energy storage water heater, it has an insulation water butt [4], it is characterized in that it also has one and has the special heated sealed kettle [1] that hot water is concentrated cover [2], between this kettle [1] and the water butt [4] to be communicated with communicating pipe [3] [6], the end that communicating pipe [3] is inserted water butt [4] is equipped with a check valve [5], thereby constitutes domestic briquet stove waste heat energy storage water heater.

2, water heater according to claim 1, the bottom that it is characterized in that adding hot-water bottle ［ 1 ］ is a curved surface, hot water is housed in the kettle concentrates cover ［ 2 ］ to director surface central authorities, is fixed on sealing and is communicated with on the joint ［ 7 ］.

3, water heater according to claim 1 and 2 is characterized in that it is a curved surface cover that hot water is concentrated cover ［ 2 ］, and its following peripheral has one or more breach or through hole.
