Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a liquid fuel combustion device used in oil stoves, oil stoves, and the like.

Conventional technology Conventionally, this type of liquid fuel combustion device uses a thermoelectric element to drive a fan with the output of the thermoelectric element. There was a known device that blows out warm air and uses this warm air, along with radiant heat from the combustion tube, to efficiently heat the room. (For example, Utsukai Sho 57-105
501 Publication) Problems to be Solved by the Invention However, with the above configuration, the conversion efficiency of the thermoelectric element from heat input to electrical energy is very poor at about 5% (Energy and Resources; Vol. 5fL3 (1984) ),
Current Status of Thermoelectric Conversion Elements, Tetsuo Maruyama) In order to fully utilize the capabilities of thermoelectric elements, it is necessary to increase the temperature difference between the heating section and the cooling section. However, in conventional methods, the heat dissipation efficiency of the cooling part of the thermoelectric element is poor due to natural heat radiation, and it is not possible to increase the temperature difference between it and the heating part.
I couldn't get enough output. Therefore, unless a large number of thermoelectric elements are used, there is a problem that the amount of hot air is small and the room cannot be efficiently heated.

The present invention solves such conventional problems, and aims to efficiently heat a room by driving a reflector with a small output of thermoelectric elements and widening the radiation range of radiant heat.

Means for Solving the Problems In order to solve the above problems, the liquid sintered combustion device of the present invention rotates a lower body including an oil tank and a combustion tube, and an upper body including a reflector through bearings. A heat absorbing fin, a thermoelectric element, and a heat dissipating fin are installed in close contact with each other in order from the bottom with an interval from the upper part of the combustion tube, and a gear provided on the lower body and a ring provided on the upper body. It is constructed so that shaped gears mesh with each other.

Effects According to the present invention, with the above-described configuration, the radiant heat emitted from the combustion tube is reflected on the driven reflecting plate, and this radiant heat is radiated over a wide range, thereby efficiently heating the room.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIGS. 1 to 4, 1 is a fuel tank, and 2 is a combustion tube installed on top of the fuel tank 1. 3 is a heat absorption fin, 4 is a thermoelectric element, and 5 is a heat radiation fin, and the champions are closely attached in order from the bottom. The heat absorption fins 3 are spaced apart from the combustion tube 2 via the support rods 6, and the heat radiation fins 5 extend outside through the top plate 9 of the upper body 8 which includes the reflection plate 7 and has an open front surface. A space is provided between the radiation fins 5 and the top plate 9.

Reference numeral 10 denotes a motor, which is installed on the upper surface of a portion of the heat dissipating fin 5 with a notch cut out, and is connected to the thermoelectric element 4 and an electric circuit (not shown), and a gear 11 is attached to the shaft of the motor 1o. . Reference numeral 12 denotes a ring-shaped gear, which is attached to the back surface of the top plate 9 on a concentric axis with the combustion cylinder 2, and meshes with the gear 11.

13 is the lower surface of the upper body 8, 14 is the combustion tank 1 and the combustion tube 2
The two are rotatably connected via a bearing 15 installed on a coaxial axis with the combustion tube 2.

In the above configuration, when combustion in the combustion tube 2 starts, the heat absorption fins 3 are heated by the combustion heat, and the heat absorption capacity of the heat absorption fins 3, the thermal conductivity of the thermoelectric element 4, and the heat dissipation capacity of the heat dissipation fins 5 cause the thermoelectric element 4 to be heated. The temperatures of the heating and cooling parts are determined.

The heat dissipation capacity of the heat dissipation fins 5 is small because it is dominated by natural convection, and the temperature of the cooling part of the thermoelectric element 4 becomes relatively high. Accordingly, the temperature difference between the heating section and the cooling section becomes smaller, and accordingly, an output smaller than the maximum capacity of the thermoelectric element 4 can be obtained. However, it is sufficient to rotate the motor 10. The output of the thermoelectric element 4 causes the motor 10 to rotate, and the gear 11 attached to the shaft of the motor 10 rotates to move the ring-shaped gear 12, causing the upper body 8 to slowly rotate. As the upper body 8 rotates, the reflection plate 7 also rotates.
The radiant heat reflected by the reflector plate 7 is widely radiated into the room while changing its radiant radiation, making it easy to efficiently heat the room. Furthermore, the rotation angle of the reflector plate 7 can be arbitrarily set using a circuit, a limit switch, etc., and a narrow area can be heated.

Effects of the Invention As described above, the liquid fuel combustion apparatus of the present invention provides the following effects.

(1) Since the reflector is configured to rotate around the combustion tube using the output of the thermoelectric element, the radiant heat reflected by the reflector is widely radiated into the room, allowing efficient heating.

(2) By using circuits, limit switches, etc., the angle of rotation of the reflector can be arbitrarily adjusted to heat only the necessary areas.
