It is an integral structure; the stove includes a slag box, a slag removal device, a backfire device, a furnace core, a furnace platform, a flue, a flue damper and a chimney; There are several vortex sheets around the pan, and the energy is transferred to the bottom of the pot in a whirlwind manner, so as to achieve the purpose of rapid and uniform heating. There is a gap between the hearth plate, the body of heater and the furnace core, which is communicated with the flue of the stove, the back wind pipe and the chimney. The upper end of the reverse wind pipe communicates with the flue and the furnace hall, and the lower end communicates with the gap between the furnace core and the water tank. It is convenient to transfer the incompletely burned gas and the heat energy brought out to the furnace core for re-combustion and utilization, and it is also convenient for the soot to be discharged outside. The water inlet pipe of the ring-shaped water storage tank is located at the bottom of the water storage tank side and is connected with the running water pipe. There is a slag discharge pipe at the bottom of the water tank. The water outlet pipe of the ring-shaped water storage tank is located on the other side above the water storage tank, and is equipped with a safety valve and a water valve to exhaust and control the water outlet. The lower end of the furnace core is placed on a slag removal device composed of several iron bars, and the coal is placed on the slag removal device. A backfire device is arranged on the top of the slag removal device, and the bottom is communicated with the air inlet of the slag box.

Beneficial effect:

Simple in structure, reasonable in combination, easy to use, saves fuel, is conducive to the full use of heat energy, and solves the problem of no smoke in the room. In addition to cooking, it also has the function of using hot water at the same time, and can also be used as a heater at the same time, etc. Function usage.

A specific embodiment of the present utility model is as follows:

An environment-friendly and energy-saving coal-fired water heater stove is composed of a ring-shaped water storage tank, a stove, a stove pan, and a return air duct. The ring-shaped water storage tank (8) has an insulation layer (9), a water inlet pipe (21), a water outlet pipe (11), a safety valve (16), a water valve (12), and a slag discharge pipe (10) as an integral structure ; The cooking range comprises a slag box (1), a backfire device (2), a slag removal device (14), a furnace core (3), a flue (6), a flue damper (18), a chimney (7), a stove top (17 ), the fire cover (19) and the furnace hall cover (15); the hearth disc (4) is an inverted conical body with a large upper part and a smaller lower part, and is placed on the upper end of the furnace core (3), and there are several vortex sheets (5) , the hearth plate (4) and the hearth (17) furnace core have a gap to communicate with the back wind duct (13) and the flue (7) of the stove; , the furnace (4) communicates, and the lower end communicates with the gap between the furnace core (3) and the water tank. There is a certain gap with the water storage tank (8) outside the furnace core (3) of the cooking range. There is insulation layer (9) outside the water storage tank. Water inlet pipe (21) is to be located at the below of water storage tank (8) side, joins with running water pipe. Water outlet pipe (12) is located at the other side above water storage tank (8), and safety valve, water valve are equipped with on the water outlet pipe, exhaust and control water outlet. The bottom of the water tank is provided with a slag discharge pipe (10). The lower end of the furnace core is placed on a slag removal device (14) composed of several iron bars, the solid fuel is placed on the slag removal device, and a backfire device is arranged on the slag removal device, and the lower end communicates with the air inlet of the slag box (1) . After the water storage tank (8) was full of water, the burning briquettes were placed in the furnace core (3), and most of the heat energy produced by the combustion of the briquettes passed through the furnace plate (4) and the vortex sheet (5), so that the heat energy was in the furnace (4) ) to rotate upwards to transfer the energy to the bottom of the pot in a concentrated manner, so as to achieve rapid and uniform heating and increase the firepower at the same time. When the gas produced by incomplete combustion and the waste heat it carries pass through the flue, it is returned to the stove by the wind pipe installed there, and is burned and heated again. At the same time, a lift is generated in the stove to accelerate the air circulation and further improve firepower. The thermal energy in the flue and the waste heat on the outer wall of the furnace core are transferred to the ring-shaped water storage tank (8), so that the temperature of the water in the water storage tank is continuously increased, and under the protection of the insulation layer (9), the water storage tank (8) The thermal energy inside is accumulated and stored in the water. As long as the fuel in the furnace core (3) has thermal energy to release, hot water can be supplied at any time. If you need to take a bath, some leather pipes and showers can be added to lead the hot water to the bathroom for use. If need heating, open (9) thermal insulation layer and get final product. The hot water water pipe or other tools in the water tank can also be led to the usefulness of heating on the ash box (20) of the cooking range.
