Abstract

The utility model discloses a multifunctional energy saving water heating stove, which is composed of a stove core, a water tank and a stove barrel. The utility model is characterized in that the top of the stove core is provided with a firing chamber, a hot-air chamber is arranged at the outer side of the firing chamber, the firing chamber is communicated with the hot-air chamber by a fire hole, a heat exchanging pipe is arranged in the water tank, one end of the heat exchanging pipe is communicated with the hot-air chamber, and the other end of the heat exchanging pipe is communicated with a chimney. The utility model has the advantages that residual heat of a coal stove has heat exchange with water through the heat exchanging pipe, the thermal efficiency is improved, the energy source is saved, the waste gas is exhausted out through the chimney, and the gas poisoning damage for the human body is avoided. Hot water not only can be used directly, but also can be used as a heat source of a heater.

Description

The energy-saving multi-purpose domestic hot-water stove

The utility model relates to a kind of energy-saving multi-purpose domestic hot-water stove, especially fire-tube type energy-saving multi-purpose domestic hot-water stove.

At present, vast rural area of China and small town citizen, restaurant, catering trade great majority still use the coal furnace heating to cook, and the various energy-saving stoves of selling on the market, adding hot water will be delivered to heat in the water by clay combustion chamber, heat-insulation layer, heat-transfer effect is poor, and the thermal efficiency is low, causes energy waste.

The purpose of this utility model is to provide a kind of modified energy-saving multi-purpose domestic hot-water stove, by changing heat transfer type, makes full use of waste heat, to overcome above-mentioned shortcoming.

Solution of the present utility model is: establishes fiery chamber and hot gas chamber at furnace roof, in water tank, establishes heat exchanger tube, and heat exchanger tube waste gas is all outdoor through the chimney discharge, thus reach the raising thermal efficiency, the purpose of energy savings.

The utility model is made up of combustion chamber 1, water tank 2, chimney 3, it is characterized in that a fiery chamber 4 is arranged at the top of described combustion chamber 1, and there is a hot gas chamber 5 outside of fiery chamber 4, has fire hole 6 to communicate between fiery chamber 4 and the hot gas chamber 5; Be provided with heat exchanger tube 7 in the described water tank 2, an end of heat exchanger tube 7 communicates with hot gas chamber 5, and the other end communicates with chimney 3.

The utility model has the advantages that the waste heat of burner is concentrated in the fiery chamber at combustion chamber top and hot gas chamber is sealed in indoor and the draft by chimney of hot gas, hot gas is imported in the heat exchanger tube, through with water tank in water carry out heat exchange after, waste gas is discharged into outdoor through chimney, thereby strengthened heat exchange area, improved the thermal efficiency, saved the energy, fire chamber and hot gas chamber separate, carry out heat transmission by fire hole, just reduced the ash content that enters heat exchanger tube, the hot water in the water tank is after threeway is drawn, both can directly use, also can make the thermal source of hot-water stove.

Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.

Fig. 1 is a structural representation of the present utility model, wherein, and 1-combustion chamber, 2-water tank, 3-chimney, 4-fire chamber, 5-hot gas chamber, 6-fire hole, 7-heat exchanger tube, 8-safety valve, 9-threeway, 10-bell, 11-bell handle, 12-water tank blow-off pipe, 13-air door, 14-water inlet pipe.

Fig. 2 is the left side view of Fig. 1, wherein, and 2-water tank, 3-chimney, 7-heat exchanger tube, 10-bell, 11-bell handle, 12-blow-off pipe, 15-ash releasing tube.

Referring to Fig. 1-2 as can be known, when the user cooks cooking, just bell 10 is opened, pot is placed on the fiery chamber 4, combustion gas part in the combustion chamber 1 rises to food in the heating kettle of the bottom of a pan, another part is because of being subjected to the resistance in the bottom of a pan, enter again in the heat exchanger tube 7 after entering hot gas chamber 5 by fire hole 6, after water in hot gas in the heat exchanger tube 7 and the water tank 2 carries out heat exchange, waste gas all enters chimney 3 and is discharged into outdoor, cold water inlet 14 and hot water threeway 9 can replenish cold water respectively and take hot water in the case, and this hot water also can be used as the thermal source of warmer, and the dirt in the water tank 2 is discharged by blow-off pipe 12.Ash in the chimney 3 is then discharged through ash releasing tube 15.When need not cook, during cooking, just bell 10 is covered, combustion gas still can enter hot gas chamber 5 by fiery chamber 4 and fire hole 6, water in heat exchanger tube 7 heating water tank 2 then, the heat-insulation layer of combustion chamber 1 is also with the water in the part heat transferred water tank 2, so simultaneously, heat transfer by pipe type heat transfer and combustion chamber heat-insulation layer combines and is fully used with regard to the waste heat that makes stove, thereby improved the thermal efficiency greatly, chimney 3 is concentrated and waste gas is discharged outdoor, has avoided the generation of gas poisoning.
