Abstract
The utility model relates to a condensation type gas heating water heater and provides a smoke-discharge pipe used in condensation type gas water heaters. The smoke-discharge pipe used in the condensation type gas water heaters is a double-layer pipeline composed of a double-layer straight pipe and a double-layer elbow pipe connected in butt joint mode. The double-layer elbow pipe comprises an outer elbow pipe and an inner elbow pipe, while the double-layer straight pipe comprises an outer straight through pipe and an inner straight through pipe. The inner straight through pipe and the inner elbow pipe constitute an exhaust pipe provided with an exhaust passage, the outer straight through pipe and the outer elbow pipe constitute an outer sleeve, and a gap between the exhaust pipe and the outer sleeve is an air-inlet passage. The inner straight through pipe is longer than the outer straight through pipe, and a seal ring is arranged in a tail end opening of the outer straight through pipe so that a tail end opening of the air-inlet passage is sealed. Several smoke-discharge holes are uniformly arranged on the tail section of the inner straight through pipe extending out of the outer straight through pipe, and several air-inlet holes are arranged in a lower half portion of the tail section of the outer straight through pipe. The outer end of the inner straight through pipe is close above an outer end opening of the outer straight through pipe. The smoke-discharge pipe used in the condensation type gas water heaters has the advantages that the phenomenon that rain water flows backward is effectively avoided by changing distribution positions of the air-inlet holes of the smoke-discharge pipe and the problem that condensate water drips outwards is effectively solved by inclining an inner smoke-discharge sleeve upwards.
Description
Technical field
The utility model relates to condensed type combustion gas heating hot water stove or gas instantaneous water heater.
Background technology
The existing employed smoke exhaust pipe of condensed type combustion gas water heater is the coaxial-type smoke pipe of using common wall hanging stove basically, and its function is from outdoor suction fresh air and preheating, and waste gas after burning is discharged outdoor.The balanced type burner is a closed system, and the needed air of burner combustion is all from outdoor suction, and combustion product is discharged in the outside atmosphere and goes.The suction of coaxial balanced-flue, aiutage are a concentric sleeve; Outer layer sleeve suction chamber outer air; The power situation is not influenced by outdoor wind-force, because when the air suction inlet of wind to exterior wall, equally blow on the flue gas discharge opening yet; Both suffered pressure is identical, so furnace pressure can not change (this also is the cause that is called as balanced type).Simultaneously, the flue gas of discharge can improve the family expenses machine thermal efficiency with the fresh air preheating.
The structure of the employed smoke exhaust pipe of existing condensed type combustion gas water heater is as shown in Figure 1; It is the double-skin duct that is made up of double-deck straight tube and the butt joint of double-deck bend pipe; Double-deck bend pipe includes outer bend pipe 4 and the interior bend pipe 3 that is fixed in the outer bend pipe 4, and double-deck straight tube includes outer straight pipe 2 and the interior straight pipe 1 that is fixed in the outer straight pipe 2, and interior straight pipe 1 constitutes blast pipe with interior bend pipe 3; In the blast pipe is exhaust passage 10; Outer straight pipe 2 and outer bend pipe 4 formation outer tubes, the gap between blast pipe and the outer tube is an inlet channel 20, interior straight pipe 1 away from interior bend pipe 3 end overlength in outer straight pipe 2; Be provided with sealing ring 5 in the end port of outer straight pipe 2; Make the end port sealing of inlet channel 20, outer straight pipe 2 has several air admission holes 21 away from the latter end of outer bend pipe 4, and the latter end that interior straight pipe 1 stretches out outer straight pipe 2 evenly has several exhaust smoke holes 11.
There is following problem in the existing employed smoke pipe of condensed type combustion gas water heater:
Since the air inlet orifice ring around being positioned at the chimney end, when the wall hanging stove when working rainy day, when outer layer sleeve sucked air, rainwater also can pour in down a chimney through air admission hole and gets in the stove, this can cause occurring a series of problems;
2. because the exhaust gas temperature of condensation stove is relatively low, can produce condensed water and downward drippage at smoke pipe exhaust opening place, contaminated environment.
The innovation and creation content
The purpose of the utility model is a kind of smoke exhaust pipe that is used for the condensed type combustion gas water heater of design, and it can effectively solve rainwater and pour in down a chimney phenomenon, also solves the problem that condensed water drips outward simultaneously.
The purpose of the utility model can realize through following:
A kind of smoke exhaust pipe that is used for the condensed type combustion gas water heater, it is the double-skin duct that is made up of double-deck straight tube and the butt joint of double-deck bend pipe, said double-deck bend pipe includes outer bend pipe and the interior bend pipe that is fixed in the outer bend pipe; Double-deck straight tube includes outer straight pipe and the interior straight pipe that is fixed in the outer straight pipe, and interior straight pipe and interior bend pipe constitute blast pipe, is the exhaust passage in the blast pipe; Outer straight pipe constitutes outer tube with outer bend pipe; Gap between blast pipe and the outer tube is an inlet channel, and interior straight pipe in outer straight pipe, is provided with sealing ring in the end port of outer straight pipe away from interior bend pipe end overlength; Make the end port sealing of inlet channel; Outer straight pipe has several air admission holes away from the latter end of outer bend pipe, and the latter end that interior straight pipe 1 stretches out outer straight pipe evenly has several exhaust smoke holes, it is characterized in that: all air admission hole is positioned at the latter end Lower Half of outer straight pipe; Interior straight pipe and outer straight pipe disalignment, promptly in the external port top of the outside straight pipe in outer end of straight pipe lean on partially, interior straight pipe spool with respect to 1～4 ° of the axial upper deflecting of outer straight pipe.
The characteristics of the utility model are:
1. through changing the position of arranging of smoke pipe air admission hole, make air admission hole be positioned at the latter end Lower Half of outer straight pipe, the rainwater that can effectively overcome smoke pipe like this pours in down a chimney phenomenon;
2. through making internal layer smoke evacuation sleeve toward tilting, can make condensed water on the smoke evacuation sleeve along the smoke evacuation sleeve wall toward interior stream and collect, effectively overcome the problem that condensed water drips outward.
