Specific embodiment

As shown in Figures 1 to 5, the utility model includes: shell 1, burner 2, burner gas supply assembly 3, heat exchanger 5 With heat exchanger water supply component 4, heat exchanger is located at the top of burner, and heat exchanger 5 is by absorbing pipe 51 and heat absorbing fins 52 Composition, heat absorbing fins arranged in sequence is on absorbing pipe.Burner and heat exchanger are fixed on before support plate 6, support plate Fixed expansion water tank 7 below.

As shown in Figures 6 to 9, the heat absorbing fins 52 are equipped with arc-shaped surface 521, and arc-shaped surface, which is located at, to be surrounded It absorbs heat on the heat absorbing fins in 53 outside of pore, wherein the one side of heat absorbing fins is the arc-shaped surface of protrusion, and another side is corresponding Position is recessed arc-shaped surface, and one side is just made by press machine punching press and protrudes, the recessed arc-shaped curved surface of another side, each suction Hot fin structure is identical, and the installation direction of heat absorbing fins is identical, that is, the arc-shaped surface protruded is both facing to left side or both facing to the right side Side, the convex surface of one of heat absorbing fins of two adjacent in this way heat absorbing fins and the concave surface position pair of another heat absorbing fins It answers, gap is equipped with after installing between convex surface and concave surface, the circulation of burner flame heat is used between gap, it is bright due to being curved surface It is aobvious bigger than plane heat absorbing fins endotherm area.

Working principle of the utility model is: when wall-hung boiler have heating demand starting, heating system pressure under normal circumstances, water Pump startup pushes the heating water flowing in heat exchanger, opens heating water flow switch or heating system water flow sensing unit, exports water Signal (switching signal or pulse signal) is flowed to circuit board, and circuit board is connected to after water-flow signal, and starting blower cleans before carrying out (3s~10s), and whether normally to detect various safety devices (blast switch, temperature controller, protected by temperature limitation etc.), in various peaces It in the normal situation of full device, lights a fire, then opens gas valve I and II valve respectively, combustion gas enters burner in electric spark Under the action of light combustion gas and burn, during igniting, blower is generally half-speed operation or power-off by coasting, to After point ignition, rotation speed of fan is determined according to gas quantity.For using the type of gas ratio valve, proportioning valve branch thermoelectricity Stream, minimum current, maximum current, it is adjustable respectively, flame normal combustion is made by ion sense flame technology, burned flame will Flow through the hot water heating of heat exchanger.After the heating temperature for reaching setting, stops working and enter standby mode.General wall-hung boiler is to setting 5 degree of temperature or more stop working, and reach 5 degree of set temperature or less starting wall-hung boilers, recycle repeatedly.There is health hot water demand , tap or water tank water temperature drop are opened, wall-hung boiler immediately enters hot-water mode, and heating stops.

The interior of shell of the utility model further include: burner gas supply assembly 3 and heat exchanger water supply component 4, further includes: Expansion tank, water circulating pump, gas valve, triple valve, electric-controlled box component composition.

Effect is the power that circulating water flow generates that flow is big, pressure is small.It has filled on water circulating pump and has been arranged automatically built in one Device of air, when having bubble in order to avoid water pipe, the water flowing of systemic circulation generates noise.Fan section is by motor, wind wheel, blower The composition such as shell, cooling fan and Venturi tube.Being rotated using motor drives wind wheel to rotate, wind wheel and Fan casing collective effect, meeting Negative pressure is generated in air intake vent and sucks gas, and the exhaust gas of wall-hung boiler burning is discharged from exhaust outlet by force.The effect of cooling fan is Agitation air cools down motor, prevents motor overheating；Venturi tube is to extract blower negative pressure supply blast switch to which judgement is useless Whether gas is unimpeded to be discharged to outdoor.Blast switch is made of microswitch and pressure differential disc.Using the diaphragm in pressure differential disc in left and right pressure The pressure difference of room changes the break-make situation of microswitch.Gas ratio valve is made of two solenoid valves, a proportioning valve and valve body. There are two effects for proportioning valve, first is that being switched off and on for control gas circuit, plays the role of safeguard protection；Second is that passing through master control borad Control, automatically adjusts the size of tolerance, reaches the size for changing flame, achievees the purpose that energy conservation and efficient burning.Mainly by electricity Control box, water circulating pump, blower, blast switch, gas valve, circulating water flow switch, the detection of health hot water priority switch, heating temperature Device, health hot water hygrosensor and anti-overheat temperature controller composition.Electric-controlled box is the core part of whole wall-hung boiler, including master control Plate and adjusting panel.Master control borad: primary recipient and output control signal pass through the work of control igniter, solenoid valve and proportioning valve Make state and finally realizes heating constant temperature and health hot water constant temperature.Adjusting panel is for showing wall-hung boiler working condition and user's tune Section uses parameter.Water circulating pump: the utility model is equipped with electrical equipment control part:

The utility model is not limited to above-mentioned embodiment, without departing from the claims of the utility model, For the personnel of the basic knowledge with the utility model fields, implementable many variations, these modifications also belong to this reality With novel protected range.
