Description
Technical field
The utility model relates to a kind of heating equipment, especially a kind of water heater for heating utilizing fuel gas buring heat supply.
Background technology
Gas-heating water heater is a kind of conventional heating equipment, it mainly utilizes gas ratio valve to control to enter, and air capacity that the gas quantity of combustion chamber and blower fan blast makes combustion gas burn in a combustion chamber by the effect of ignition electrode, produce heat, heat cold water in water tank and combustion gas being produced in the effect by heat exchanger carries out heat exchange, reach the heat effect to cold water in water tank, thus make user obtain the hot water of relevant temperature, traditional gas-heating water heater mainly comprises water tank, combustion chamber assembly, burner assembly, ignition electrode, the parts such as blower fan assembly, the blower fan that gas-heating water heater conventional at present uses is generally constant speed split-pole blower fan, and constant speed split-pole assembling is above combustion chamber, blower fan wind speed is constant, can not speed governing, and be by peak load design air flow during gas-heating water heater design, when normal users uses gas-heating water heater heating, most of the time is operation at part load, at this moment the air quantity of blower fan will be excessive, efficiency is caused to decline serious, energy consumption increases, when minimum burning or maximum combustion, rotation speed of fan is invariable, heat loss is large, amount of consumed gas is many. high fume temperature, blower fan is easily aging, fan performance is caused to be decayed fast, the service life of constant speed split-pole blower fan reduces, and combustion gas is in imperfect combustion state in most cases, combustion gas utilization rate is low, in the flue gas of discharging, pernicious gas amount is large, have a strong impact on the use of water heater for heating, therefore these defects of prior art are urgently improved.
Utility model content
The purpose of this utility model is overcome above-mentioned the deficiencies in the prior art and provide a kind of water heater for heating improving combustion gas utilization rate and service life of fan, solves the problem that gas-heating water heater fuel gas buring is insufficient, exhaust smoke level is large, heat loss is serious and service life of fan is lower of prior art.
For achieving the above object, the technical solution adopted in the utility model is:
Gas-heating water heater, comprising the gas ratio valve for controlling combustion gas inlet, controlling the blower fan of intake, burner assembly for combustion gas and air well-mixed combustion chamber assembly, an ignition action, exhaust fume collecting hood, for stored hot water water tank, control the water pump complement of output, described burner assembly is provided with ignition electrode, combustion heat exchanger and split flow plate is also provided with in burner assembly, described assembling in the lower end of combustion chamber assembly and the air inlet of blower fan be connected with combustion chamber assembly, described blower fan is frequency conversion fan.
As the further setting of such scheme, the rotating speed of frequency conversion fan is 900r/min--1800r/min.
As the further setting of such scheme, described frequency conversion fan is brush DC frequency conversion fan.
As the further setting of such scheme, the intake of described blower fan is synchronous with the air inflow of gas ratio valve.
It is constant speed split-pole blower fan that the technical program mainly solves the blower fan that gas-heating water heater of the prior art adopts, and blower fan is generally all mounted in the position of upper end near exhaust fume collecting hood of combustion chamber assembly, such structure not only makes the Long-term service temperature of blower fan compare, reduce the service life of blower fan, and the wind speed of constant speed split-pole blower fan is all constant, can not speed governing, and be by peak load design air flow during gas-heating water heater design, when normal users uses gas-heating water heater heating, most of the time is operation at part load, at this moment the air quantity of blower fan will be excessive, efficiency is caused to decline serious, energy consumption increases.When minimum burning or maximum combustion, rotation speed of fan is invariable, heat loss is large, amount of consumed gas is many, and the utility model changes structure and the core part of traditional gas-heating water heater, adopt frequency conversion fan and by the lower end of assembling at combustion chamber assembly, make blower fan operationally away from the exhaust fume collecting hood that temperature is higher, ensure that temperature during fan operation, and adopt frequency conversion fan to substitute original constant speed split-pole blower fan, the air inflow of gas ratio valve and the synchronous of intake can be realized by the change of the rotating speed of frequency conversion fan, thus enable to enter the combustion gas of combustion chamber assembly and fully mixed by the air that frequency conversion fan blasts, ensure that the efficiency of combustion of combustion gas, improve the utilization rate of heat energy.
The beneficial effects of the utility model: by the replacing of key components and parts in the structure to traditional gas-heating water heater, extend the service life of key components and parts blower fan, improve the combustion rate of combustion gas and the utilization rate of heat energy, also reduce the discharge of pernicious gas during fuel gas buring simultaneously.
