Description

A kind of gas fired water heater
Technical field
The utility model belongs to field of water heaters, especially relates to a kind of gas fired water heater.
Background technology
Balance type gas water heater is current safest gas heater.Compare with straight-line, forced-ventilated two class water heaters, the maximum of balance type gas water heater is not both it can form a sealing system of isolating with room air together with supporting flue, does not consume room air, also can not cause smoke pollution.The balance type gas water heater needed oxygen that burns is from outdoor absorption, the waste gas producing is also outside discharge chamber, so just can not consume indoor oxygen, can not cause the situations such as indoor anoxic, therefore, balance type gas water heater can be arranged in toilet or bathroom.
The feature of balance type gas water heater maximum is by water heater supply and exhaust system and burning work system is direct and open air is connected, and separates completely with indoor.Its shell seals, and the flue that joins together of shell makes inside and outside two-layerly, and flue leads to outdoor from wall.The air needing when water heater operation is from outdoor by the skin supply of flue, and the flue gas generating after burning is discharged to outdoor from the internal layer of flue, room air is neither consumed, and does not also pollute, safe and reliable.
Traditional balance type gas water heater adopts integral seal structure, comprises four parts, water heater body's hermetically-sealed construction; Give, exhaust uptake and the water heater sealing while combining; Sealing when giving, combining between the sealing of exhaust uptake self and flue.There are following several problems in integral seal structure: 1, integral seal structure complexity, especially large-scale machine; 2, sealing effectiveness is not easy to ensure, the damage producing when transport and slight deformation can cause sealing not firm; 3, the place of sealing is a lot, cannot ensure the long-term sealing effectiveness using; Unless 4 with special equipment, otherwise cannot detect sealing effectiveness; 5, water heater O-ring seal is in use easily subject to heat ageing, or through factors such as maintenance personal's being dismounted for multiple times, destroy its sealing, cause burnt gas to be leaked in room air, when imperfect combustion, the burnt gas such as CO or NOx can direct harmful to human safety, in addition also can be because extracting for a long time room air, the in the situation that of airtight in room, can produce burning insufficient, problem that cannot normal combustion.
Patent CN201014701Y discloses a kind of balance type gas water heater, mainly formed by the combustion chamber in shell body and housing, heat exchanger, igniter, inlet and outlet pipe, air inlet and exhanst gas outlet, air inlet is connected with combustion chamber, exhanst gas outlet is communicated with top, combustion chamber, wherein be communicated with the inlet channel of air inlet and combustion chamber, the discharge flue that is communicated with exhanst gas outlet and top, combustion chamber is hermetically-sealed construction, is also provided with air blast on inlet channel.The advantages such as that this balanced type water heater has is simple in structure, good heat dissipation, but exhanst gas outlet is communicated with top, combustion chamber, although also can solve the problem of integral sealing, because high-temperature flue gas passes through heat exchanger heat exchange from bottom to top, top at heat exchanger produces condensed water, condensation water collection difficulty.In addition, owing to containing acidic materials in flue gas, in the time that flue-gas temperature drops to dew point, just have sub-fraction acidic materials be condensed water absorb, formation has the acid condensate water of highly corrosive, condensed water drips from top to bottom and can corrode heat exchanger heat transmission equipment and flue, thus the service life of reducing water heater, the security that impact is used.
Utility model content
The purpose of this utility model is in order to solve above-mentioned deficiency, and provide a kind of gas fired water heater, heat exchanger is positioned at burner below, high-temperature flue gas passes through heat exchanger heat exchange from top to bottom, produces condensed water in the bottom of burner, is convenient to collection and the discharge of condensed water, prevent that condensed water from corroding heat exchanger under hot conditions, water heater long service life, adopt simultaneously independent sealed, good sealing effect.
The technical solution of the utility model is:
A kind of gas fired water heater, comprise burner, heat exchanger, air intake duct, gas inlet pipe and smoke exhaust pipe in housing and housing, air intake duct and gas inlet pipe are connected with burner, burner is connected with heat exchanger, between air intake duct, gas inlet pipe, heat exchanger and burner, be and be tightly connected, it is characterized in that, heat exchanger is arranged at burner below, smoke exhaust pipe is connected with heat exchanger, and smoke exhaust pipe is sealedly connected on heat exchanger below.
This gas fired water heater is in whole combustion system, only have smoke exhaust pipe and air intake duct to communicate with the external world, air is passed into burner by air intake duct, flue gas leads to outdoor through smoke exhaust pipe, the entrance of air intake duct leads to outdoor through pipeline, the air used that ensures to burn is taken from outdoor, so just can form an independently sealing system, prevent that gas leakage from arriving indoor, also prevented that gas heater from extracting room air for a long time, the in the situation that of airtight in room, can produce burning insufficient, problem that cannot normal combustion.Heat exchanger is arranged at burner below, and burner is positioned at top, and the high-temperature flue gas after burning flows from top to bottom, through heat exchanger heat exchange, discharges by the smoke exhaust pipe of heat exchanger bottom, and heat exchanging process carries out in water heater bottom.
Heat exchanger is arranged at burner below, there is following impact: first, because the density ratio air of combustion gas, NO, CO is little, heat exchanger is placed in to burner below, the imperfect combustion product in a flue gas upwards flows and continues to participate in reaction until fully burning, therefore, fuel gas buring is more abundant, and rough burning product reduces, and has reduced the ratio of pollutant component in flue gas, raise the efficiency, more energy-conservation.Secondly, condensed water is collected at heat exchanger foot, greatly reduced the region of condensate corrosion, only need heat exchanger foot to carry out preservative treatment, reduced cost.Again, improved heat exchange efficiency, reached energy-saving effect, thereby minimizing air consumption reduces the total release of flue gas, has reduced the discharge of corrosive gas.Finally, in flue gas, the reduction of corrosive gas content can cause the minimizing of acid ingredient in condensed water, has further reduced the corrosion of condensed water to water heater.
