Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a combustion heating device used for indoor heating.

[Technical background of the invention and its problems]

Recently, a fan for indoor air circulation has been built into the housing of a combustion heating system, and this fan is driven by the electromotive force of a thermoelectric element to forcefully circulate indoor air and improve the efficiency of indoor heating. (Utility Model Publication No. 105501, 1983). To explain this further, the inside of the housing is partitioned by a partition plate into a lower fuel chamber and an upper heat radiation chamber, and the fuel chamber is provided with a fuel storage tank and the heat radiation chamber is provided with a combustion tube. The fuel storage tank has a fire pan at its upper end, and the upper end of the wick for sucking up fuel faces the fire pan. The combustion cylinder is placed on the fire pan through an opening formed in the partition plate. A reflector plate is provided on the back side of the combustion tube to radiate combustion radiant heat toward the front side of the housing, and a discharge port is formed in a part of the reflector plate facing the combustion tube. A fan is provided inside the discharge port, that is, between the reflector and the back surface of the casing, and a thermoelectric element is arranged around the grate so as to face the grate.

Then, the upper end of the lamp wick is ignited with the upper end facing the fire pan, and with this ignition, the lamp wick sequentially sucks up the fuel in the fuel storage tank and vaporizes it from the upper end, and the vaporized gas is transferred to the combustion tube. It burns as it rises inside. The tip of the thermoelectric element is heated by the heat around the fire pan, and based on this heating, an electromotive force is generated, and the above-mentioned fan is driven by this starting force. This drive causes air to be blown from the discharge port toward the combustion cylinder.

However, in such a conventional configuration, the air for forced circulation of indoor air is sent toward the combustion tube, which may worsen the combustion condition in the combustion tube. The sent air is overcome by the exhaust gas rising vigorously from the combustion tube, and most of it rises with the exhaust gas, reducing the amount of air flowing toward the front of the housing, making it difficult to circulate indoor air sufficiently. Become.

Therefore, it is conceivable to arrange a fan in the fuel chamber and send out air from the front of the housing. However, if a fan is simply disposed in the fuel chamber, the suction force of the fan will reach around the fire pan at the upper end of the fuel storage tank, and there is a risk that the combustion state in the fire pan will deteriorate.

[Purpose of invention]

The present invention was developed with attention to these points, and its purpose is to prevent deterioration of combustion conditions, and to improve efficiency by blowing a sufficient amount of air in front of the housing. An object of the present invention is to provide a combustion heating device capable of achieving indoor heating.

7 is connected to the radiator 32 of the thermoelectric elements 40 through a link mechanism 59. When the ignition lever 57 is pulled down, the radiator 32 rotates rearward about the pin 36 via the link mechanism 59, and the tips of the thermoelectric elements 40 retreat to the rear side of the combustion tube 15. Further, the combustion tube 15 is pushed up so as to be inclined rearward by a push-up mechanism (not shown), and a part of the periphery of the fire pan 8 is opened. Ignition is now carried out by

A fuel storage tank 4 is provided in the space on one end side of the housing 1.
A cartridge tank 60 that sequentially supplies fuel while maintaining a constant level at all times is housed inside the cartridge tank 60 so as to be insertable and removable from above. The space on the opposite side of the cartridge tank 60 is the propeller fan 52.
It is also used as an arrangement part for a motor 51 for driving the same. In addition, 61 is a protective guard that covers the radiator 32, and 62 is a heat shield plate provided horizontally on the outer periphery of the lower end of the fire pan 8.

Next, the effect will be explained. At the start of combustion operation, the upper end of the lamp wick 9 is made to face the fire pan 8 via the ignition lever 57, and the upper end is ignited. With this ignition, the lamp wick 9 sequentially sucks up the fuel in the fuel storage tank 4 and vaporizes it from its upper end. The vaporized gas vaporized from the upper end of the lamp wick 9 rises between the inner and outer flame tubes 16, 17 of the combustion tube 15, and passes through the respective ventilation holes 19..., 20 of the two flame tubes 16, 17.
It is mixed with combustion air supplied from... and burned. The high-temperature exhaust gas from this combustion rises above the combustion tube 15, and therefore each tip of the thermoelectric elements 40 disposed above it is heated to a high temperature of about 400°C. Furthermore, the radiant heat of combustion is radiated to the front of the housing 1. On the other hand, the base ends of the thermoelectric elements 40 are efficiently cooled to about 100°C by the heat dissipation action of the radiator 32 and the heat sink 41, and therefore there is a large temperature difference between the tips and bases of the thermoelectric elements 40. This generates a large electromotive force. The electromotive force drives the motor 51 and rotates the propeller fan 52. According to this rotation, indoor air is sucked from the opening 30 on the back of the housing 1 through the gap 10 into the area where the fan 52 is disposed. The air is discharged to the front of the housing 1 through the discharge port 46, thereby achieving forced circulation of room air and achieving efficient heating of the entire room. The propeller fan 52 and the fire pan 28 are isolated by the wind shield 53, so the suction force of the fan 52 does not reach the periphery of the fire pan 8. The combustion condition is always kept stable without deterioration. When indoor air flows in through the opening 30 and passes through the gap 10, the air is heated by contact with the reflecting plate 25, so that warm air is sequentially discharged from the discharge port 46. Also, as the propeller fan 52 rotates, the duct 4 is opened from the slit 49.
Relatively low temperature indoor air flows little by little around the motor 51 through the motor 8, and this air prevents the motor 51 from overheating. The air forcibly circulating indoor air does not pass around the combustion tube 15 at all, so the combustion condition in the combustion tube 15 is always stable and a good combustion condition is maintained. The air blown into the room is from the combustion tube 15.
Therefore, a sufficient amount of air can be reliably blown in front of the casing without being affected by the rising air current rising from the casing, thereby greatly improving indoor heating efficiency. can.

In the above embodiment, a propeller fan was used as a fan for forcibly circulating indoor air, but this may be any other type of fan, and the power source for driving the fan may be a thermoelectric element. However, the present invention is not limited to this, and may also be a case where a commercial power source is used.

[Effect of idea]

As explained above, according to the present invention, the combustion exhaust gas in the combustion tube rises above the casing, the radiant heat of combustion is dissipated to the front of the casing, and the back side of the reflector is The air that has been circulated and turned into warm air is discharged to the front of the housing, and the discharged air can forcefully circulate the air in the room, making it possible to efficiently heat the entire room. In addition, since the fan, the fuel storage tank, and its fire pan are separated by a wind shield, the wind caused by the rotating operation of the fan does not affect the combustion part, which can lead to deterioration of the combustion condition. The effect is that a stable combustion state can be maintained at all times without any problems.
