Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a supply/exhaust type heating system that uses petroleum as fuel, and is particularly concerned with an indoor supply/exhaust type heating system in this heating system. The present invention relates to a supply/exhaust device that can be selectively used as an outdoor supply/exhaust port.

(Prior art) Generally, in homes in cold regions, a collective chimney is connected to the exhaust pipe of a heating device such as a pot stove, and the exhaust gas generated when the heating device is burned is passed through the collective chimney to the outside. It is designed to exhaust air to.

Therefore, in the case of the collective chimney, the heating device uses indoor air for combustion, and the collective chimney is used exclusively for exhaust gas.

On the other hand, heating devices using kerosene heaters are not only fixed-installation types, but users are also required to use fixed-installation types that can be freely moved from one room to another. It is desired that a heating device provided with supply/exhaust pipes for type heating can be used as an indoor supply/exhaust type for indoor heating/exhaust type heating.

(Problem to be solved by the invention) However, in the above-mentioned heating device equipped with supply/exhaust pipes, the supply/exhaust pipes are constructed as double pipes that are integrated at their outer ends, and furthermore, they extend rearward. Because of the installation and piping, it is difficult to use the supply and exhaust pipes as they are.

The present invention was developed in view of the above-mentioned circumstances, and in a heating device equipped with supply and exhaust pipes, a T-shaped elbow is provided at the exhaust port of the heat exchanger, and both exhaust ports of the T-shaped elbow are provided with a T-shaped elbow at the exhaust port of the heat exchanger. Attach the blind plate selectively and removably, connect the exhaust pipe to the other exhaust port of the T-shaped elbow when using outdoor supply/exhaust type heating, and use it selectively for indoor supply/exhaust. The purpose of the present invention is to provide a heating device that can be used by converting it into exhaust heating and room supply/exhaust heating.

[Structure of the idea]

(Means for Solving the Problem) The present invention provides a heat exchanger inside the case body, attaches a T-shaped elbow to the exhaust port of this heat exchanger, and connects one exhaust port of the T-shaped elbow to the case body. It is installed facing the warm air outlet of the main body, and blind plates are selectively and removably attached to both exhaust ports of this T-shaped elbow, so that when using outdoor supply/exhaust type heating, exhaust is directed to the other exhaust port of the T-shaped elbow. The pipe is connected to the supply/exhaust pipe so that outdoor supply/exhaust type heating and indoor supply/exhaust type heating can be selectively used.

(Embodiment of the invention) Hereinafter, the present invention will be described with reference to an illustrated embodiment.

In FIGS. 1 to 3, reference numeral 1 denotes a flat stand, and this stand 1 has a box-shaped case body 2 installed therein. A fuel tank 4 storing (petroleum) 3 is provided. Further, a board 5 which also serves as a partition plate is provided horizontally above the fuel tank 4, and a burner outer cylinder 6a is mounted on this board 5.
A combustion device (burner device) 6 having a fuel tank 4 is installed so as to be supplied with the fuel 3 from the fuel tank 4 by a fuel pump 7. Furthermore, a spark plug 8 is attached to a part of this combustion device 6, and a cylindrical combustion cylinder 9 is erected on the upper part of the burner outer cylinder 6a where this spark plug 8 is located. There is. Furthermore, a heat exchanger 10 having a meandering passage is connected to one side of the upper part of the combustion tube 9, and an exhaust port 10a of the heat exchanger 10 has an exhaust port 10a as shown in FIG. A T-shaped elbow 11 forming a T-shape is attached. Also, one exhaust port 11a of this T-shaped elbow 11 is arranged toward the hot air outlet 12 provided at the lower front of the case body 2, and the other exhaust port 11b of this T-shaped elbow 11 is , is connected to a base 14a of a double-pipe supply/exhaust pipe 14 via an L-shaped exhaust pipe 13.

Note that one exhaust port 11 of the T-shaped elbow 11
A is covered with a blind lid 15 during outdoor supply/exhaust type heating using outdoor supply/exhaust.

On the other hand, a combustion air fan 17 equipped with a drive motor 16 is installed in the case body 2 near the T-shaped elbow 11, and the air supply port 17a of this air supply fan 17 is connected to the double It is connected to the air supply passage of the supply/exhaust pipe 14 forming a pipe, and the discharge port 17b of the air supply fan 17 communicates with the lower part of the combustion device 6 through the air duct 18.
Further, a convection blower 19 is installed at the upper part of the case body 2, and this convection blower 19
The fluid heat-exchanged by the heat exchanger 10 or the like is configured to flow out into the room from the hot air outlet 12.

The operation of the present invention will be explained below.

1 When used as an outdoor supply/exhaust type heating device.

As shown in FIGS. 2 and 3, in advance,
A blind cover 15 is attached to one exhaust port 11a of the T-shaped elbow 11, and the other exhaust port 11b of the T-shaped elbow 11 is supplied with air via an exhaust pipe 13.
Connect the exhaust pipe 14.

By igniting the spark plug 8 attached to the combustion device 6, the fuel in the combustion device 6 mixes with the combustion air supplied from the combustion air fan 17 through the blower duct 18 and combusts. .

In this way, the combustion tube 9 of the combustion device 6
The combustion gas is subjected to secondary combustion, and is transferred to the heat exchanger 10, where heat is exchanged, and then exhausted to the outside from the exhaust port 14b of the exhaust pipe 13 and the supply/exhaust pipe 14.

On the other hand, the heat-exchanged hot air fluid is sent into the room from the hot air outlet 12 by the convection blower 19 to heat the room. In this case, since one exhaust port 11a of the T-shaped elbow 11 is tightly plugged, the exhaust gas will not be exhausted into the room.

2 When used as an indoor supply/exhaust type heating device.

As shown in FIGS. 4 and 5, in advance,
One exhaust port 11a of the T-shaped elbow 11 is opened, and the other exhaust port 11b is opened with the blind lid 15.
Seal it tightly.

In this way, the exhaust gas heat-exchanged in the heat exchanger 10 is sent into the room together with hot air fluid from the exhaust port 11a of the T-shaped elbow 11 to the hot air outlet 12, thereby heating the room. It's summery.

[Effect of idea]

As described above, according to the present invention, the heat exchanger 10 is provided inside the case body 2, and the T-shaped elbow 11 is attached to the exhaust port 10a of the heat exchanger 10.
One exhaust port 11a of the T-shaped elbow 11 is provided facing the hot air outlet 12 of the case body 2, and a blind cover 15 is selectively and removably attached to both exhaust ports 11a and 11b of the T-shaped elbow 11. During outdoor supply/exhaust heating, the other exhaust port 1 of the T-shaped elbow 11
1b has an exhaust pipe 13 and a supply/exhaust pipe 14 forming a double pipe.
Because it is connected so that it communicates with
Moreover, since the exhaust gas is discharged from the hot air outlet during indoor heating and exhausting, there is no risk of reducing combustion efficiency.
