Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a heating machine equipped with a combustor that heats a heat medium distribution pipe of a heating radiator.

(Prior Art) Conventionally, as shown in FIG. 2, a first combustor 20 for indoor heating and a heat medium distribution pipe 31 of a heating radiator (not shown) are disposed in a radiation stove main body 10. radiator heat exchanger 30 and upper exhaust passage 4
1 and a lower exhaust passage 42, and both ends of the lower exhaust passage 42 face the exhaust port 21 of the first combustor 20 and the intake port 32 of the radiator heat exchanger 30, respectively. One end side of the lower exhaust passage 42 communicates with one end side of the upper exhaust passage 41, and each of the lower exhaust passages 42 and 40 are connected from one end side of the lower exhaust passage 42 to the upper exhaust passage 41 and the upper exhaust passage 41, respectively. A heater equipped with a damper 50 that controls the flow of exhaust gas to the intake port 32 is known.

According to this heater, when only radiation heating is performed, the intake port 32 is closed by the damper 50. As a result, the exhaust gas from the combustor 20 passes through the lower exhaust passage 42 and is further exhausted outdoors via the chimney 60.

In addition, when performing heating using radiation heating and a heating radiator, the damper 50
Open 2. As a result, the lower exhaust passage 42
The exhaust gas flows into the radiator heat exchanger 30, and further flows through the exhaust port 33 of the radiator heat exchanger 30.
The air flows into the indoor heating heat exchanger 40 and is exhausted from the chimney 60. In such a case, the heat medium in the heat medium distribution pipe 31 is heated by the exhaust gas, and the heat is radiated by the heating radiator.

(Problems to be solved by the invention) In the conventional heater, the heating source is the combustor 2.
0, the radiator heat exchanger 3
The amount of heat exchanged between the exhaust gas and the heat medium at 0 is small, and there is a problem in that the heating radiator cannot perform sufficient heating. In addition, in order to solve this problem, the amount of combustion in the combustor 20 may be increased, but this results in a larger amount of radiant heat from the combustor 20 and the indoor heating heat exchanger 40 than necessary. The problem is that the temperature inside the room cannot be maintained at an appropriate temperature.

In view of the above-mentioned conventional problems, the present invention does not increase the combustion amount of the first combustor for room heating.
It is an object of the present invention to provide a heater that can not only increase the heat radiation amount of a heating radiator but also change the temperature of a heat medium in a heat medium distribution pipe of a heating radiator as appropriate.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the heating machine according to the invention includes a first combustor for indoor heating and a heat medium distribution pipe of a radiator for heating. The disposed heat exchanger for the radiator and the second combustor that heats the heat medium distribution pipe form an upper exhaust passage and a lower exhaust passage, and both ends of the lower exhaust passage are connected to the first combustor. An indoor heating heat exchanger that communicates with an exhaust port of a combustor and an inlet of the radiator heat exchanger, and exhaust gas that has flowed into the indoor heating heat exchanger from the first and second combustors. each end of the lower exhaust passage communicates with both ends of the upper exhaust passage, and the exhaust port of the radiator heat exchanger communicates with the upper exhaust passage, and the indoor heating heat is The exchanger includes a first damper that controls opening and closing of the exhaust gas from one end of the lower exhaust passage to the upper exhaust passage and the exhaust gas to the intake port of the radiator heat exchanger, respectively;
The present invention is characterized in that a second damper is provided that controls opening and closing of the flow of exhaust gas from the other end side of the lower exhaust passage to the upper exhaust passage.

(Function) According to the present invention, the first damper opens the intake port of the radiator heat exchanger located at one end of the lower exhaust passage, thereby communicating the lower exhaust passage with the radiator heat exchanger. On the other hand, the second damper closes the communication state from the other end of the lower exhaust passage to the upper exhaust passage.

As a result, the exhaust gas from the first combustor flows from the lower exhaust passage into the radiator heat exchanger through this intake port. This inflowing exhaust gas heats the heat medium within the heat exchange distribution pipe. The heat medium in this heat exchange flow pipe is also heated by the second combustor.

Further, when the chimney is installed at the other end of the lower exhaust passage, the second damper allows communication from the other end of the lower exhaust passage to the upper exhaust passage. This results in
Exhaust gas that has flowed into the indoor heating heat exchanger from the first and second combustors is smoothly discharged.
