Four edges of the water collection sheet are distinctly connected with a gear wall 602~608, the gear wall 604 being located on rear side of the water collection sheet
And the gear wall 606,608 of arranged on left and right sides abuts the back side panel 44, left plate 46 and right plate of the second shell 36 respectively.Definition
The water collection sheet 58 is a leading edge 586 adjacent to the edge of the front side board 42, the leading edge 586 be located at the position of the corresponding opening 422 and
It is separated by one first distance L1 with the front side board 42 in a horizontal direction.The water collection sheet 58 is from the leading edge 586 toward far from before this
The direction of edge 586 tilts down setting, and the gear wall 608 in 58 right side edge of water collection sheet has a circular hole 608a, the circular hole
608a is correspondingly arranged with the discharge outlet 486 on the right plate 48, to allow the water that the water collection sheet 58 is collected from 486 row of discharge outlet
Go out the second shell 36.The design of those gear walls 602~608 can avoid water from the marginal flow of the water collection sheet 58 to underlying
In main heat exchanger 26.And the lower surface that the gap between the upper and lower plate body 582,584 can avoid the lower body 584 touches
Aqueous vapor is condensed when high-temperature gas.
Cover board 62 is located at the outside of the front side board 42, and the direction of periphery toward the front side board 42 of the cover board 62 extends to form one
Flanging 624, the flanging 624 have the screw hole 424 that a plurality of perforation 624a correspond to the front side board 42.The cover board 62 and the front side board
A sealing element 64 is equipped between 42, which is made of rubber material, and is arranged around the opening of the front side board 42, should
Sealing element 64 is also equipped with a plurality of perforation 642.The perforation 624a of 62 flanging 624 of cover board is passed through by a bolt 66 again and this is close
The perforation 642 of sealing 64 makes the cover board 62 removably be linked on the front side board 42, and closes the opening 422.
The cover board 62 has an inner face, and towards the front side board 42, the leading edge 586 of the inner face 622 and the water collection sheet 58 is in phase
It is separated by a second distance L2 on same level direction, and second distance L2 is more than first distance L1.And the cover board 62 herein in connection with
There is a partition board 68, a gap is formed between the partition board 68 and the inner face 622 of the cover board 62.The partition board 68 and the water collection sheet 58
Leading edge 586 is separated by a third distance L3 in identical horizontal direction and forms a channel P, and the third distance L3 between this first
Between distance L1 and second distance L2.In other words, which forms the structure protruded outward, to allow channel P to have enough
Space pass through for high-temperature gas.
By above structure, in use, high-temperature gas caused by the burner 18 burning gas, by the burner 14
Up enter inside the first shell 28 of the main heat exchanger 26 in shell 16, and those heat absorbing sheets 32 and the water-supply-pipe 30 plus
Hot pipe section 302 absorbs the thermal energy of part, to heat the water by the heating pipeline section 302.At this point, the high-temperature gas that has surplus heat of band after
It is continuous up to climb sharply into the second shell 36 of the secondary heat exchanger 34, and by being guided via the water collection sheet 58, by this
Channel P is formed by between the leading edge 586 of water collection sheet 58 and the partition board 68, using between those endless tubes 566 by the top plate
Second exhaust port 382 on 38 is discharged outside the second shell 36.With this, those endless tubes 566 can reabsorb the waste heat of part, with
It is preheated to entering the water in the endless tube 566.The water preheated by the relay pipe 52 inject the water-supply-pipe 30, and again into
Enter and heated in the main heat exchanger 26, thus, which the waste heat of the main heat exchanger can be effectively utilized, reduction is supplied to
The gas of burner achievees the effect that save the energy.
In addition, high-temperature gas with carbon dioxide and aqueous vapor generation, sour water will be condensed into those endless tubes 566, and
Naturally it drops on the water collection sheet 58, follows the discharge outlet 486 and be drained to the outside of the second shell 36, so can avoid acid
Water instills in the main heat exchanger 26, and causes 30 corrosion of those heat absorbing sheets 32 and water-supply-pipe.
It should be noted that being removably set to the design on the front side board 42 by the cover board 62, user can be allowed
After the outer cover 12 of the water heater is removed, you can separate the cover board 62, convenient for cleaning those endless tubes 566.Cleaning those rings
During pipe 566, an additional baffle (not shown) across the gear wall 602 in 58 leading edge 586 of water collection sheet and is stretched out this
Opening 422, you can avoid water by being instilled in the first shell 28 between the leading edge 586 of the water collection sheet 58 and the front side board 42.Punching
The water of those endless tubes 566 is washed, is equally discharged from the discharge outlet 486 of the second shell 36.It will be further appreciated that the cover board 62
With the gap of the partition board 68, can avoid condensation of moisture in instilled in the main heat exchanger 26 on the partition board 68 cause embroider lose.
In conclusion water heater of the present invention can effectively utilize the waste heat of high-temperature gas to the ring in secondary heat exchanger 34
Pipe 566 is preheated.And the cover board 62 of secondary heat exchanger 34 can be separated from the second shell 36, convenient for user to this second
Pipeline inside shell 36 is cleared up, and the chance that endless tube 566 embroiders erosion is reduced, and water collection sheet 58 helps to collect those endless tubes
The sour water of 566 condensation drippages, to be discharged in outer by discharge outlet 486.
