Abstract

An air-return water heater, which can recover high-temperature residual heat at a boiler chamber burner and heat water in a water storage tank co-joined with the boiler chamber, comprises an air inlet pipe, a movable boiler core, the double-layer boiler chamber with a bell mouth, an air return passage in the boiler chamber, the half-moon elliptic water storage tank, a heat exchanger in the water storage tank, a waste gas discharge pipe and balance brackets, wherein, the air inlet pipe, the boiler core, the boiler chamber, the residual heat passage, the heat exchanger and the waste gas discharge pipe are mutually communicated so as to form an airflow passage; and during frying, when a heating piece, such as a pot, a kettle and the like, is placed on the burner of the boiler chamber, the high-temperature fire flow is ejected out of the boiler core, sequentially enters into the boiler chamber, the air return passage and the heat exchanger in the water storage tank for heating the water in the water storage tank, and finally is discharged outside through the waste gas discharge pipe. The air-return water heater has the advantages of high heat efficiency, energy conservation, safety and practicability.

Description

The return air water heater
Affiliated technical field:
The utility model relates to a kind of return air water heater, and it can carry out hot water from the water tank water storage that the burner hearth burner reclaims high-temperature residual heat pair and burner hearth disjunctor.Because the return air effect of return air water heater, the function of its cooking of cooking has obtained obvious reinforcement.
Background technology:
At present, no matter be general stove and accessory among the people, or all kinds of stove and accessorys of supplying on the market, all fail to reclaim the burner waste heat, the high temperature fire flows after pot, the kettle bottom transient heating, and high-temperature residual heat is discharged into rapidly in the air, is not always the case since ancient times, has greatly wasted the energy.
Summary of the invention:
Be discharged into airborne deficiency in vain in order to overcome existing stove and accessory high-temperature residual heat; The utility model return air water heater; The high-temperature residual heat return flow line is set in burner hearth, heat exchanger is set in the storage tank, realized reclaiming the purpose of burner hearth burner high-temperature residual heat pair and the water tank water storage hot water of burner hearth disjunctor.
The utility model solves the technical scheme that its technical problem adopted: confirm water tank and burner hearth on demand, the burner hearth square crossing is inlayed and is welded in the storage tank, and burner hearth is made as bilayer; Stove tube and outer furnace tube promptly; For improving the operating efficiency of return air water heater, the storage tank cross section is made into the flat semilune of circle down, and outer furnace tube is made into cylindric toroidal; In the upper and lower symmetry of the storage tank of horizontal positioned really on the allocation shell; Open upper and lower mouthful of identical circular hole of two diameters and outer furnace tube, horn mouth outer furnace tube is up put into two circular holes of water tank, inlay water tank and outer furnace tube according to circular hole and be welded into integral body.Width position in the storage tank of horizontal positioned is with the laterally arrange heat exchanger of rectangle pipeline configuration of water tank, heat exchanger left end thermal current inlet; Be welded on left side under the outer furnace tube horn mouth, pass outer furnace tube, with outer furnace tube internal heat airflow reflux channel connection; The outlet of heat exchanger right-hand member thermal current; Pass storage tank right-hand member shrouding, be welded on the shrouding, the exhaust pipe outer with being arranged on water tank is communicated with.The outer furnace tube dead ahead is passed the water tank bottom position blast pipe is set, and in outer furnace tube, with the fair position of water tank bottom, the filler ring grate is set.The same with the outer furnace tube shape but do not have horn mouth, be lower than make less than outer furnace tube in the stove tube, on outer furnace tube filler ring grate, under the horn mouth, in outer furnace tube inside, promptly form the high temperature gas flow return flow line to interior stove jacket casing between the inside and outside stove tube.Interior stove tube center is provided with movable combustion chamber; Fill up insulation material between combustion chamber and the inner furnace tube wall; When cook, cooking outside the stove nozzle press pot, during the kettle heating member, blast pipe, combustion chamber, burner hearth, return air channel thus, heat exchanger in the storage tank; Exhaust pipe is interconnected, and forms the high-temperature residual heat path.When the return air water heater is lit a fire when cooking, high temperature fire stream is to after the heating member transient heating, and high-temperature residual heat gets into return air channel; Through the outer furnace tube wall water tank water storage is conducted heat; High-temperature residual heat then gets into heat exchanger in the water tank, the water tank water storage is further heated the waste gas that heat exchanger outlet is discharged; Get into exhaust pipe, discharge outdoor through the door and window top.Be handled easily, balance bracket be set at the water tank bottom of return air water heater.The water tank surface is provided with the 3-4cm heat-insulation layer, and the combustion chamber of return air water heater is arranged to active state, changes honeycomb briquette or other fuel of combustion chamber incendivity different size.
The beneficial effect that the utility model produces: 1, return air water heater, except that all functions with general stove and accessory, its peculiar function of tool also; Promptly do not allow the burner high-temperature residual heat to be discharged in the air, introduced heat exchanger, the water tank water storage is heated by air-return duct; Water temperature raises in the water tank, conversely burner hearth has been protected temperature again, favourable raising burner hearth fire temperature; Make fuel combustion abundant, stove fire is prosperous, and the acting ability is strong.2, provide free satisfied sufficient again hot water to the user for a long time.
The return air water heater is provided with and reaches outdoor exhaust pipe, helps environmental friendly indoor; Because the guide functions of exhaust pipe; Improve the flowing velocity of thermal current in the air-return duct, impelled the burner hearth fuel fully to burn, further improved the operating efficiency of return air water heater.
