Description
Technical field
The utility model relates to a kind of volumetric gas water heater.
Background technology
In the prior art; Volumetric gas water heater is provided with a storage tank usually; The storage tank bottom is equipped with burner, and the centre of storage tank is provided with discharge flue, directly heats the water in the storage tank through burner combustion; And flue gas directly discharged from the top, the water heater temperature-sensing valve cuts off the gas valve burn-out automatically when temperature is set when water temperature reaches.The flue gas that burns during because of water heater working is directly discharged from the top, and exhaust gas temperature is higher, the common volumetric gas water heater thermal efficiency about 75%; It is bigger to consume gas quantity; Defectives such as not energy-conserving and environment-protective cause to exist exhaust gas temperature higher, and the volumetric gas water heater thermal efficiency is lower.For overcoming these defectives, volumetric gas water heater is improved.
Summary of the invention
The utility model technical problem to be solved is that a kind of volumetric gas water heater will be provided, and it can make exhaust gas temperature reduce effectively, effectively promotes the volumetric gas water heater thermal efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises water heater housing, main heat exchange storage tank, burner, water inlet pipe, outlet pipe; The main heat exchange storage tank is arranged on the water heater enclosure interior, filling-foam layer between main heat exchange storage tank and the water heater housing, and burner is installed in the below of main heat exchange storage tank; The centre of main heat exchange storage tank is provided with discharge flue; Outlet pipe is communicated with the main heat exchange storage tank, and it also comprises auxiliary heat exchange storage tank, and auxiliary heat exchange storage tank is installed in the top of main heat exchange storage tank; Water inlet pipe is communicated with auxiliary heat exchange storage tank, and auxiliary heat exchange storage tank is communicated with the main heat exchange storage tank.
It also comprises storage tank communicating pipe, and auxiliary heat exchange storage tank is communicated with through storage tank communicating pipe with the main heat exchange storage tank.
Water inlet pipe is communicated with the bottom of auxiliary heat exchange storage tank.
Storage tank communicating pipe one, end was communicated with the top of auxiliary heat exchange storage tank, and its other end is communicated with the bottom of main heat exchange storage tank.
It also comprises spoiler, and spoiler is arranged in the discharge flue.
Burner is an atmospheric burner.
The capacity of auxiliary heat exchange storage tank is 20L～50L.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model adopts auxiliary heat exchange storage tank, and auxiliary heat exchange storage tank is installed in the top of main heat exchange storage tank, water inlet pipe is communicated with auxiliary heat exchange storage tank; The structure that auxiliary heat exchange storage tank is communicated with the main heat exchange storage tank; Form twice heat exchange of main heat exchange storage tank and auxiliary heat exchange storage tank, water makes full use of fume afterheat successively through the heat exchange of two heat exchange storage tanks; So it can make exhaust gas temperature reduce effectively, effectively promotes the volumetric gas water heater thermal efficiency.
Description of drawings: Fig. 1 is the structural representation of the utility model.
The specific embodiment: shown in accompanying drawing 1; Present embodiment comprises water heater housing 1, auxiliary heat exchange storage tank 2, main heat exchange storage tank 3, burner 4, water inlet pipe 6, outlet pipe 7, storage tank communicating pipe 8; Main heat exchange storage tank 3 is arranged on water heater housing 1 inside; Filling-foam layer 5 between main heat exchange storage tank 3 and the water heater housing 1, burner 4 is installed in the below of main heat exchange storage tank 3, and the centre of main heat exchange storage tank 3 is provided with discharge flue 9; Outlet pipe 7 is communicated with main heat exchange storage tank 3; Water inlet pipe 6 is communicated with auxiliary heat exchange storage tank 2, and auxiliary heat exchange storage tank 2 is through being communicated with main heat exchange storage tank 3 storage tank communicating pipe 8, and auxiliary heat exchange storage tank 2 can be installed in the top of main heat exchange storage tank 3.
For strengthening the heat exchange effect, can set up spoiler, spoiler is arranged in the discharge flue 9.
The capacity of auxiliary heat exchange storage tank 2 can be 20L～50L, effectively controls the product machine volume, and convenient the installation.
During operate as normal; The main heat exchange storage tank 3 of burner 4 direct heated base, the high-temperature flue gas that fuel gas buring produces passes from discharge flue 9, after high-temperature flue gas and the spoiler heat exchange; Carry out heat exchange with auxiliary heat exchange storage tank 2 again, fully become low-temperature flue gas after the heat exchange and discharge.High-temperature flue gas can effectively utilize the heat of flue gas through twice heat exchange, reaches the purpose that promotes the thermal efficiency.
Outside cold water gets into the bottom of auxiliary heat exchange storage tank 2 earlier from water inlet pipe 6; Flowed out by the storage tank communicating pipe 8 from auxiliary heat exchange storage tank 2 tops after the flue gas heating; Flow into the bottom of main heat exchange storage tank 3, carry out secondary heat exchange, finally be heated into hot water and flow out confession user use from outlet pipe 7.
Through two heat exchange storage tanks are set, constitute two-stage water storage heat-exchanger rig, the top is auxiliary heat exchange storage tank 2; As a heat exchange storage tank; The top is a main heat exchange storage tank 3, and as the secondary heat exchange storage tank, water flows through heat exchange storage tank and secondary heat exchange storage tank successively; With the abundant heat exchange of high-temperature flue gas, make high-temperature flue gas after twice heat exchange, become low-temperature flue gas and discharge.Can effectively utilize the heat of flue gas, improve the volumetric gas water heater thermal efficiency, the gas heater thermal efficiency is reached more than 90%.Simultaneously also reduce gas consumption, reached the good result of energy-conserving and environment-protective.
