Described heat exchange screen is the screen shape structure of interlaced overlapping setting.
The screen shape structure of described heat exchange screen for making a circulation mutually to be arranged in parallel.
Be provided with the water pipe that at least one links to each other with water channel between the described heat exchange screen.
Bottom, described combustion chamber is the structure to the combustion chamber convex.
Described combustion chamber is a composite chamber, and the internal diameter of combustion chamber reduces from bottom to top step by step.
Described combustion-chamber shape is the frustum of a cone.
Outer wall of the present utility model is provided with at least one air-supply oral region, this air-supply oral region by water channel at interval, be provided with a plurality of air outlets on the sidewall of combustion chamber in this air-supply oral region, fuel can fully contact with air, make full combustion of fuel, reach no black smoke and produce the beneficial effect of few flue dust, simultaneously, outer wall of combustion chamber beyond the air-supply oral region directly contacts with water, chamber wall is cooled off fully, can not be out of shape fusing because of fire box temperature is too high, general like this refractory material just can be satisfied the demand, and needn't adopt the very high refractory material of refractoriness as the furnace wall, has reduced cost, and outer wall of combustion chamber directly contacts with water and also increased heat exchange area, improved the thermal efficiency.
In a preferred implementation of the present utility model, the bottom of combustion chamber is the structure to convex, this structure has improved bearing capacity, and the bottom surface area of this structure is bigger than the bottom surface area of plane combustion chamber, increased the contact area of fuel and air, the fuel of bottom, combustion chamber can be burnt more fully.
In another preferred implementation of the present utility model, the heat exchange screen is that the screen shape structure of interlaced overlapping setting, this structure make flue gas can directly discharge body of heater, and does not need by air-introduced machine flue gas to be drawn body of heater, has reduced energy consumption.Preferably, also be provided with the water pipe that links to each other with water channel between the described heat exchange screen, the setting of this water pipe can increase heat exchange area, improves the thermal efficiency, has also played the effect of reinforcing simultaneously.
In another preferred implementation of the present utility model, the heat exchange screen is mutually circuitous parallel screen shape structure, flue is the space between heat exchange screen and the heat exchange screen, because the heat exchange screen is mutually circuitous parallel screen shape structure, this just make the same flue of flue, water channel with water channel and flue with being parallel to each other between the water channel, this circuitous parallel construction of heat exchange screen helps the heat-exchange time of prolong smoke at flue, increased the heat exchange area of flue gas and water, effectively reduced exhaust gas temperature, significantly reduce incrusted speed, improved the thermal efficiency.Preferably, also be provided with the water pipe that links to each other with water channel between the described heat exchange screen, the setting of this water pipe can increase heat exchange area, improves the thermal efficiency, has also played the effect of reinforcing simultaneously.
The high-efficient energy-saving environment friendly water heater that the utility model provides can make full combustion of fuel, improves the thermal efficiency, reduces cost.
