なっている。Conventionally, in this type of stove, a combustion tube 32 is connected above a burner 31, as shown in FIG. 4, and a main heat exchanger 33 is connected to the combustion tube 32. Fuel is sent to the burner 31 by a fuel pump 34 and combustion air is sent by a blower 35. A hot water pipe 36 is inserted in the middle of the main heat exchanger 33.
The hot water heat exchanger 37 having a branch is provided, and a damper 38 for switching the flow of the combustion gas is provided at the branch portion, and is configured to control the temperature of the hot water by controlling the combustion gas passing through the hot water heat exchanger 37. Have been. Further, the hot water heat exchanger
37 has an outlet connected to the main heat exchanger 35 and an exhaust
It leads to 39. In addition, this stove includes a sub tank 40 for hot water and a circulation pump 41,
Hot water is circulated through a floor heating panel (not shown).

気されることとなる。In the stove configured as described above, during simultaneous operation of floor heating and radiant heating from the stove, the fuel pump 34 and the blower 35 are started, the fuel is burned by the burner 31 to form a flame, and the generated combustion gas When the damper 38 has opened the hot water heat exchanger 37 side after passing through the combustion tube 32, it passes through the hot water heat exchanger 37 and heats the hot water pipe 36,
Warm the water flowing through it. The warmed water is sent to the floor heating panel by the circulation pump 41 to perform floor heating. At this time, the damper 38 is connected to the hot water heat exchanger 37 or the main heat exchanger.
It rotates to the 33 side and controls the temperature of hot water. In addition, this type of stove rotates the damper 38 toward the main heat exchanger 33 without operating the circulation pump 41 and closes the hot water heat exchanger 37 to perform radiant heating from the stove without performing floor heating. You can also do just that.
In the case of the stove alone operation, the combustion gas does not flow to the hot water heat exchanger 37, but is heat-exchanged and exhausted only by the main heat exchanger 33.
発明が解決しようとする課題 このような従来の温水熱交換器内蔵型ストーブでは、

良くする手段も必要であった。Problems to be Solved by the Invention In such a conventional stove with a built-in hot water heat exchanger,
The combustion gas passing through the hot water heat exchanger 37 is
Because the temperature of the hot water pump 36 in the inside is low, the moisture in the combustion gas tends to condense on the surface of the hot water pipe 36, and the air ratio during combustion is increased to prevent condensation (increase the excess air amount). The concentration of moisture in the combustion gas had to be reduced. However, when the stove alone is operated without performing the floor heating operation, the heat must be exchanged only with the main heat exchanger 33, and when the air ratio is increased more than necessary as described above, it becomes difficult to completely burn and the exhaust gas is exhausted. As the characteristics deteriorate, the heat exchange efficiency deteriorates, and a means for improving the heat exchange efficiency in the main heat exchanger 33 is also required.

主熱交換器で十分満足させることを目的としている。The present invention solves the above-described problems, and during floor heating operation, burns at a high air ratio without deteriorating exhaust gas characteristics,
Prevents condensation in the hot water heat exchanger, and when operating the stove alone without performing floor heating operation, the conventional main heat exchanger without increasing the air ratio more than necessary and without deteriorating the heat exchange efficiency The purpose is to satisfy them sufficiently.

ものである。Means for Solving the Problems In order to achieve the above object, the present invention provides a burner, a blower for sending combustion air to the burner, a combustion cylinder connected to the burner, and a surface communicating with the combustion cylinder. A main heat exchanger that emits heat for heating by radiation and convection from there; a hot water heat exchanger having a heat exchanger for hot water therein; and a main heat exchanger or the hot water heat exchanger for flowing combustion gas. The air passage from the blower to the burner is branched into a primary air passage and a secondary air passage, and a secondary air for adjusting an air amount is provided in the secondary air passage. A damper is provided, and the secondary air damper is moved in conjunction with the switching damper.

悪化させることがないものである。Effect of the Invention According to the above configuration, the secondary air damper adjusts the air amount in conjunction with the switching damper for switching the flow of the combustion gas to the main heat exchanger or the hot water heat exchanger. The amount of secondary air can be changed even when heating is not performed. Therefore, during floor heating operation where moisture in the combustion gas tends to dew in the hot water heat exchanger, increase the amount of secondary air (increase the air ratio) to prevent condensation and prevent floor heating. Can be sufficiently satisfied with the conventional main heat exchanger without reducing the amount of secondary air and lowering the heat exchange efficiency in the main heat exchanger as compared with the floor heating operation. Moreover,
During the floor heating operation in which the air ratio is increased, only the secondary air having little effect on combustion is increased, so that the exhaust gas characteristics are not deteriorated.

11を通して前面に輻射する。The operation will be described in the above configuration. First, when the floor heating and the radiant heating of the stove are simultaneously operated, the burner 1 sends the liquid fuel sent from the fuel pump 2 and the air sent from the blower 3 through the primary air passage 4 1. Combustion is started by the secondary air, and complete combustion is performed by the secondary air sent from the blower 3 through the secondary air passage 5 to generate combustion gas.

室外に排出される。On the other hand, for floor heating, the circulation pump 24 has started operation, and the switching damper 18 is also on the floor heating side (solid line in the figure).
Has been switched to. Therefore, the combustion gas that has passed through the red heat body 7 does not flow to the main heat exchanger 9 above the combustion cylinder 8, but flows from the branch port 14 on the back surface of the combustion cylinder 8 to the hot water heat exchanger 13. The combustion gas entering the hot water heat exchanger 13 heats the hot water pipe 12 therein, and in the hot water pipe 12, floor heating water (hot water) is passed by a circulation pump 24. The water is heated and becomes hot water, exits the hot water outlet 25 from the sub tank 23 and the circulation pump 24, and returns to the hot water return port 22 to circulate. The combustion gas that has passed through the hot water heat exchanger 13 then flows from the outlet 15 to the exhaust switching chamber 16, passes through the exhaust pipe 20, and is discharged to the outside as exhaust gas through the supply / exhaust tube 21.

りの主熱交換器で十分熱交換される。In this floor heating operation, the switching damper 18 switches the combustion gas to the main heat exchanger 9 or the hot water heat exchanger 13 to control the temperature of the hot water. , Combustion gas is hot water heat exchanger 13
When the hot water pipe 12 is heated, the amount of secondary air is large. When the hot water pipe 12 is not heated, the amount of secondary air is small. As a result, when the hot water pipe 12 is heated, the air ratio becomes high (excess air is large), and the moisture in the combustion gas does not condense on the surface of the hot water pipe 12, and only the secondary air increases. As a result, the exhaust gas characteristics do not deteriorate. When the combustion gas flows to the main heat exchanger 9, the air ratio is low, the heat exchange efficiency in the main heat exchanger 9 is high, and the heat is sufficiently exchanged by the conventional main heat exchanger.

The damper 6 also has the shape of a broken line, the secondary air is small (the air ratio is low), and the combustion gas does not flow to the hot water heat exchanger 13 but flows to the main heat exchanger 9 and is sufficiently radiated by the main heat exchanger 9. The gas enters the exhaust switching chamber 16 from the exhaust part 17 of the main heat exchanger 9 and is exhausted through the exhaust pipe 20.

When the combustion gas flows through 13 and the hot water pipe (heat exchanger) 12 is heated, the air ratio increases and the hot water pipe (heat exchanger)
The moisture in the combustion gas does not condense on the surface of 12, and the treatment of the condensed water is unnecessary. Further, when the combustion gas flows through the main heat exchanger 9, the air ratio decreases, the heat exchange efficiency in the main heat exchanger 9 is high, and the heat is sufficiently exchanged by the conventional main heat exchanger.

らかである。Although the above embodiments have been described with reference to the heat exchanger for floor heating using hot water, the present invention is not limited to floor heating, and other radiators may be used. Although the switching damper is described as being provided on the outlet side of the hot water heat exchanger, the same applies to the inlet side, and the fuel may be gaseous fuel instead of liquid fuel. Further, although the switching damper and the secondary air damper are connected by the link rod, it is obvious that the same effect can be obtained by separately providing driving means and moving them simultaneously.

である。Effects of the Invention As is clear from the above embodiments, according to the present invention, when the switching damper and the secondary air damper are linked to each other, the temperature of the hot gas when moisture in the combustion gas is easily condensed on the surface of the heat exchanger for hot water is increased. Can increase the air ratio and lower the air ratio when the hot water is not heated. Therefore, the problem of dew condensation of water in the hot water heat exchanger can be eliminated without deteriorating the combustion exhaust gas characteristics, and the means for treating the dew water and preventing dew condensation are unnecessary, and the conventional main heat The heat is sufficiently exchanged in the exchanger, and no special means for improving the heat exchange is required.
