Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a heater provided with a heat exchanger for a radiator that heats a heat medium of the radiator for heating.

(Prior Art) Conventionally, as shown in FIG. 2, a heat medium distribution pipe of a combustor 20 for indoor heating and a radiator (not shown) for heating (for example, a panel for floor heating) in a radiant stove body 10. The heat exchanger for radiator 30 in which 31 is arranged is provided, and the combustor 20 and the heat exchanger for radiator 30 are communicated with each other by the heat exchanger 40 for indoor heating through which the exhaust gas of the combustor 20 flows, and A heater is known in which a heating heat exchanger 40 is provided with a damper 50 for controlling the inflow of exhaust gas into the heat radiation heat exchanger 30.

According to such a heater, when performing only radiant heating,
The damper 50 closes the intake port 32 of the radiator heat exchanger 30. As a result, the exhaust gas of the combustor 20 passes through the indoor heating heat exchanger 40 and is further exhausted to the outside through the chimney 60. Further, when heating is performed by the radiant heating and the heating radiator, the intake port 32 is opened by the damper 50. As a result, the exhaust gas flowing through the indoor heating heat exchanger 40 flows through the intake port 32 into the radiator heat exchanger 30,
Further, it again flows into the indoor heating heat exchanger 40 from the exhaust port 33 and is exhausted from the chimney 60. In this floor warming mode, the heat medium flowing in the heat exchanger 30 for radiator is heated by the exhaust gas and radiated by the radiator for heating.

(Problems to be Solved by the Invention) In this conventional heater, since the heat source is only the combustor 20, the amount of heat exchange between the exhaust gas and the heat medium in the heat exchanger for radiator 30 is small, There has been a problem that heating by a heating radiator cannot be performed sufficiently. Further, in order to solve such a problem, it is sufficient to increase the combustion amount in the combustor 20, but this causes the radiant heat of the combustor 20 and the indoor heating heat exchanger 40 to be unnecessarily large and the indoor temperature to be a proper temperature. It has a problem that it cannot be maintained.

Further, under the low heating load in early spring or autumn, floor heating, that is, heating by only the radiator for heating is required, but in this conventional heater, the heat exchanger 40 for indoor heating must be used whenever this floor heating is performed.
Radiant heating was performed due to this, and it was not possible to cope with this low heating load, and this floor heating heating amount always corresponds to the combustion amount of the combustor 20, and only the floor heating amount or indoor radiant heating It was inconvenient because it could not be controlled individually.

In view of the above conventional problems, the object of the present invention is to increase the heat radiation amount of the heating radiator without increasing the combustion amount of the first combustor for indoor heating. Second
By individually controlling the combustion amount of each combustor, the heat radiation amount of the indoor heating heat exchanger and the heat radiation amount of the heating radiator can be adjusted individually, and further, the heat exchange efficiency of the heat medium in the heat exchanger for radiator can be improved. It is to provide a heater that can be improved.

It is characterized in that it comprises an inner cylinder arranged at a predetermined gap, and the heat medium distribution pipe is wound around the gap.

(Operation) According to the present invention, the heat medium in the heat medium distribution pipe is heated not only by the exhaust gas of the combustor for indoor heating but also by the combustor for the heat exchanger.

Further, the heating amount of the indoor heating heat exchanger and the heating amount of the heating radiator can be individually controlled by the first and second combustors.

Further, the heat exchanger for radiator is composed of an outer cylinder and an inner cylinder arranged in the outer cylinder with a predetermined gap, and a heat medium distribution pipe is wound around this gap. The heat medium is not only heated by the exhaust gas of the second combustor, but is also heated from inside and outside by the radiant heat of the outer cylinder and the inner cylinder heated by this exhaust gas.
