Accompanying drawing 5 is the left view of Fig. 4.
Among the figure: 1, burner 2, heat exchanger 3, water inlet pipe 4, secondary heat exchange device 5, sink cover 6, support 7, water receiving tank 71, water receiving tank assembly 72, flanging 8, drainpipe 9, outlet pipe.
The specific embodiment
Embodiment 1:
Shown in accompanying drawing 1,2,3, in the utility model condensed type combustion gas water heater structure diagram, it partly is made up of heat exchanger 2, water inlet pipe 3, secondary heat exchange device 4, sink cover 5, support 6, water receiving tank 7, condensate draining pipe 8, hot water outlet pipe 9 etc.Sink cover 5, support 6, water receiving tank 7 compositions prevent that condensing drip from dropping down onto the water container on the heat exchanger 2 No. one time.Sink cover 5 is the reclinate arc in two ends, is fixed on the water receiving tank 7 by support 6, and water receiving tank 7 can be by welding, rivet or be threaded and be fixed on the housing or on the miscellaneous part.Water receiving tank 7 is horizontally disposed with, and its horizontal projected area is slightly larger than or equals the horizontal projected area of secondary heat exchange device 4.In the present embodiment, because water receiving tank 7 tops have sink cover to block, so it can be designed to two water receiving tank assemblies 71 of symmetry mutually, so that economical with materials.Inward flange at water receiving tank assembly 71 is provided with flanging 72 upwards, that be used for dash, and condensate draining pipe 8 is connected the lowest part of water receiving tank assembly 71.That is to say that burner 1 is under a heat exchanger 2, mode is vertically upward adopted in burning.Secondary heat exchange device 4 is arranged on directly over heat exchanger 2, between heat exchanger 2, secondary heat exchange device 4 water container is set.Flue gas rises after through heat exchanger 2, water container, produces condensed waters through secondary heat exchange device 4 again, and condensed water flows into water container downwards because of conducting oneself with dignity, and drains smoothly from condensate draining pipe 8 then.Flue gas is then through upwards draining behind the secondary heat exchange device 4.
The present embodiment is unique to be in the sink cover 5, sink cover support 6 and the water receiving tank 7 that are arranged between heat exchanger 2 and the secondary heat exchange device 4.Sink cover 5 and water receiving tank 7 have certain clearance on vertical space, can allow flue gas pass through smoothly.Sink cover 5 can be caught partial condensation water, and its downward gradient can make condensed water converge at last in the water receiving tank 7 again.When combustion gas after burning on the burner 1, the high-temperature flue gas of generation is reduced to lower temperature after through a heat exchanger 2, arrives secondary heat exchange devices 4 by water receiving tank 7 and sink cover 5 again.Behind secondary heat exchange device 4, flue gas is directly by last discharge.Steam in the flue gas can be condensed into water at this moment, and condensed water converges in then in the water receiving tank 7 and is discharged to the outside through condensate draining pipe 8 together because of the gravity of self can drop onto on sink cover 5 and the water receiving tank 7.Condensed type combustion gas water heater in the present embodiment adopts burning and fume exhausting type vertically upward, makes condensed type combustion gas water heater similar with conventional on-condensing gas heater combustion system, to obtain maximum exchange calorific value, energy savings.And combustion technology is mature and stable, and processing technology is simple.
In the above-described embodiment, flue gas can enter secondary heat exchange device 4 from front, side or the top of water container through behind heat exchanger 2, carries out heat exchange.
Embodiment 2:
Shown in accompanying drawing 4 to 5, embodiment 2 compares with embodiment 1, and its difference only is the difference that is provided with of water container.Water container in the present embodiment is made up of independent water receiving tank 7, and an end of water receiving tank 7 is for coating the cambered surface 7 of secondary heat exchange device 4 bottoms, other end level or slightly be obliquely installed, and its both sides are fixed on the housing, and its lowest part is connected with condensate draining pipe 8.Like this, water receiving tank 7 almost wraps up secondary heat exchange device 4, only stays the front side and enters secondary heat exchange device 4 to carry out heat exchange for flue gas.After condensed water produces, can all can drop onto in the water receiving tank 7, discharge by condensate draining pipe 8 then.Flue gas then passes through secondary heat exchange device 4 backs by draining from the front side of water receiving tank 7.
