。The heat exchanger 4 includes a primary heat exchanger 4a close to the burner 5;
It is a two-stage heat exchanger type consisting of a secondary heat exchanger 4b separated from the burner 5, and has a configuration in which the water sent from the primary heat exchanger 4a side is converted into hot water by the water passing vibe 2 and sent out. In this case, - the heat absorption fins 3a of the fire heat exchanger 4a
The intervals between the heat absorbing fins 3a of the secondary heat exchanger 4b are made coarser. This is mainly due to CO from secondary combustion.
This method is used to reduce the amount of heat absorbed by the primary heat exchanger 4a.
また、燃焼排気は燃焼筐１の上部の排気口１ａから外部

A plurality of air ejection holes are provided on the circumferential surface of the heat absorbing fins 3a.■0
It consists of a copper air introduction vibe 11 arranged in a row, and air sent by a fan 12 is passed through a plurality of air injection holes IO between the primary heat exchanger 4a and the secondary heat exchanger 4b in the combustion case 1. Particularly secondary heat exchanger 4, which is prone to spouting out and causing drainage
Air is mixed into the space 13 around b.
このとき前述の如く一次熱交換器４ａの吸熱フィン３ａ
の間隔は粗であるので空気噴出孔１０を形成し晶い。At this time, as mentioned above, the heat absorption fins 3a of the primary heat exchanger 4a
Since the spacing between the holes is coarse, the air jet holes 10 are formed.

い。In this case, the combustion gas in the space 13 is diluted and its dew point temperature can be lowered below the surface temperature of the secondary heat exchanger 4b, so that no drainage occurs in the heat exchanger 4. At this time, the air introduction pipe 11 is mainly cooled by the water in the water pipe 2a of the primary heat exchanger 4a and is not overheated.

図のものが有利となる。In the above-described embodiment, the air introducing vibrator 11 was positioned directly above the water passing vibrator 2a as shown in FIG. 3, but as shown in FIG. You can let me. Comparing the two, the one in Figure 3 has a slight advantage in terms of drain prevention, and the one in Figure 4 has a slight advantage in terms of thermal efficiency.
The one shown in the figure is advantageous.
上記した実施例ではファン１２を゛、バーナ５の火勢を

。FIG. 16 and FIG. 7 show another embodiment. In this case, the air introduction vibes 11 are provided in parallel to make it easier for air to flow toward the tip side, and the tip 11a is connected to the exhaust port 1a. An opening/closing means 15 is provided in the middle. In addition, the heat exchanger 4 has its heat absorbing fins 3 composed of long fins 31 and short fins 32, and the long fins 31 and short fins 32 are arranged so that the long fins 31 and the short fins 32 are placed on the burner 5 side. The side where the fins are closely spaced is defined as the downstream side.

。さらに白煙を防止できる。The above description has been about prevention of drainage, but by mixing air in this way, it is possible to prevent the water in the water pipe 2 of the heat exchanger 4 from boiling, and therefore it is possible to prevent noise caused by the bursting of air bubbles. Furthermore, when the flame intensity of the burner 5 is reduced, the thermal efficiency increases and the capacity range cannot be widened, but by mixing air, the thermal efficiency can be lowered, and therefore the hot water output capacity can be adjusted over a wide range. . Furthermore, white smoke can be prevented.
さらにまた使用停止後の一定時間中にも回転させるよう
にすれば、後沸きを低くすることができる。Furthermore, by allowing the rotation to continue for a certain period of time after stopping use, it is possible to reduce after-boiling.

Since it is configured with an air introduction pipe, air can be mixed into the desired location, and when air is mixed into the combustion gas as in the conventional device described above, it does not affect the combustion of the burner or the air may be mixed in unevenly. This has the effect of eliminating the possibility of
