The flow passes through the circulation circuit formed between the cross-sectional plate @ (2) and is rectified by the rectifier plate @ placed at the circulation inlet (20b) of the guide tube (20b) surrounded by K and 70. It is guided and returns to the hollow s (18 m) of the guide cylinder from the circulation inlet (20b). 9th grade in middle school! The exhaust gas that has returned to the inside (18m) is again blown out from the circulation outlet (20m) to the external space of the guide tube (to) by the suction force of the fan (b), and most of it passes through the circulation circuit and reaches the circulation outlet (20b). ) returns to the hollow @ (18m), and from then on, this circulation pipe is repeated. This circulation exhaust is -
Next side heat exchange i! (4) In the primary heat exchange chamber (B) installed inside and outside the guide tube (To), the amount of heat retained therein becomes approximately equal to the temperature of the water supply in this heat exchanger (B). The exhaust gas that has undergone sufficient heat exchange work in this way becomes part of the air and flows from the exhaust communication hole (9) to the secondary heat conditioning exchange room (5). Blowout 1 body (1) is discharged to the outside. This body (
1), the exhaust gas consumes almost all of its retained energy, while the water supplied from the water inlet (2) first undergoes secondary heat exchange 1! UK flows in and is heated, and after the temperature rises to a certain degree,
After the KR water is further heated and further heated, the water is heated to the main heat exchanger 0aKR water, and is finally heated and hot water is discharged from the hot water supply opening. There is cold water inside the secondary heat exchanger.

る。In addition, because relatively low-temperature hot water flows through the second heat exchanger (b), the moisture in the combustion exhaust gas is cooled down and becomes dew, which adheres to the narrow surfaces. The water falls onto the partition plates Q4 and 01. Partition plate (M) QIC
The collected drain is drained to the outside through the drain hole (7) (6J) and finally to the drain pipe (K) (1).

備え、しかも。Thermal efficiency increases, for example, the conventional thermal efficiency of 90-95% can be increased to 95%, and when the water supply temperature is low such as in winter, it can be increased to 99% K. In addition, the fan that creates a circular pattern of exhaust gas*1 also has the function of releasing exhaust gas to the outside.

、＊械効皐もよく。The circulation is not performed in a circulation path that passes through the center S of the hot water storage tank as in conventional hot water storage water heaters, but is performed in the heat exchange chamber, that is, outside the heat exchanger, so the structure is simple and the machine is easy to use. The effect is also good.

くなる。In the above embodiments, the exhaust pipe is circulated in the downstream heat exchange chamber. In this case, the thermal efficiency will be 5-11 times higher than in the case where air is not circulated for 4 hours. 9. The secondary heat exchange chamber may be omitted, and the secondary heat exchange chamber may be configured to circulate through the exhaust pipe in either or both of the main heat exchange chambers. The thermal efficiency increases by about 591 points.
