Abstract

PURPOSE:To unnecessitate commercial AC power sources, and external power source and wirings thereof by providing a gas burner, a heat absorptive member, and a thermoelectric converter in which a heat absorptive part is fitted to said heat absorptive member so as to convert the absorbed heat to electric power. CONSTITUTION:When a gas is burnt in a region 6 by means of a gas burner 2, a heat absorptive member 4 is heated by combustion heat, and a temperature difference is produced between the heat absorptive part 9 of a thermal electric converter 8 and a heat radiating part 18 by the heating of the heat adsorptive member 4. The thermal electric converter 8 generates power based on the temperature difference, and the power is supplied to a fan 12 whereby the fan 12 is rotated to take-in external air through an opening 13. An air flow 15 generated by the rotation of the fan 12 comes into contact with a radiating member 21 while passing through an air passage 10 to carry out heat exchange, thus absorbing heat of the radiating member 21 and being humidified, while conversely, the radiating member 21 is cooled. The heated air flow 15 is delivered to the outside through one end 16 of the air passage 10 and an opening 22, and is utilized for indoor space heating, and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air generator, such as a fan heater or a gas stove, that generates and sends out heated air.

These fan heaters burn the supplied gas, use this combustion heat to heat the air they take in, and send the heated air outside using a fan driven by the power from a commercial AC power source. ing. Therefore, this conventional fan heater requires electrical wiring as well as gas piping, and is generally difficult and inconvenient to use in places where there is no commercial AC power source.

The present invention has been made in view of the above points, and it can make external power sources such as commercial AC power sources and their electrical wiring inconvenient.
Our objective is to provide a hot air generator with excellent versatility.

According to the present invention, the object is to provide a gas combustion device that burns supplied gas, an endothermic member disposed to absorb gas combustion heat of the gas combustion device, and a heat absorbing member disposed to absorb heat of gas combustion of the gas combustion device. a thermoelectric conversion device whose endothermic part is attached to the endothermic member in order to convert it into energy, and a blower electrically connected to the aging conversion device to be driven by the force converted by the aging conversion device. , an air passageway having one end disposed on the blower side and the other end opening to the outside;
A hot air generator comprising a heat radiating member disposed in the air passage to exchange heat with the air in the air passage, and a heat radiating member attached to the heat radiating part to cool the heat radiating part of the thermoelectric conversion imitation. achieved by.

Next, the present invention will be explained based on a preferred example shown in the drawings.

In the figure, the gas to be combusted by the gas supply pipe 1;
For example, a gas combustion/combustion device 2 to which city gas or propane gas is supplied has a large number of gas outlets 3, and burns the gas ejected from the outlets 3. Gas combustion device 2
The heat absorbing member 4, which is disposed opposite to the
on the surface facing the gas/combustion region 6 of the gas combustion device 2, and the heat absorbing member 4 made of, for example, a copper plate absorbs gas combustion heat in the region 6. The other surface 7 of the heat absorbing member 4
The heat absorbing part 9 of the thermoelectric conversion device 18 is attached to the heat absorbing member 18 by a contact layer or the like, and the enthusiastic converting device fi8 converts the heat absorbed by the heat absorbing member 4 into electric power by using, for example, an N-type semiconductor and a P-type semiconductor. It consists of a large number of thermoelectric conversion elements connected alternately. Housing 1 forming air passage 10
A fan 12 as a blower is provided in one of the four parts of the thermoelectric converter f8, and the fan 12 is electrically connected to the thermoelectric converter f8 via a lead wire (not shown). The fan 12 is rotationally driven by the electric power converted by the fan 12, and the air sucked in from the opening 13 side of the housing 11 is sent to the one end 14 side of the air passage 10. The other end 16 is formed to open outward 13μ.
A heat dissipation member 21 consisting of a substrate 18, a plurality of flat fins 19 integrally housed in the substrate 18, and a corrugated plate 20 fixed to the fins 19 is attached to the air passage lO. The heat dissipating member 21 disposed in, for example, is made of aluminum, contacts the air flow 15 of the air passage 10 to exchange heat, and the heat dissipating member 21 of the heat dissipating section 17 of the thermoelectric conversion device 8 is heated. Perform cooling. The heated air flow 15 of the air passage 10 is delivered to the outside through the opening 22 of the housing 11 .

In the hot air generator 30 configured in this way, the area 6
When the gas is combusted from the gas combustion equipment 21, the combustion
The heat absorption member 4 is heated by the baking heat, and this heating of the heat absorption member 4 causes a temperature difference between the heat absorption part 9 and the heat radiation part 17 of the heat conversion device 8. generates power based on the I power and sends this I power to the fan 12.
The fan 12 is thereby rotated to draw in outside air through the opening 13. While passing through the air passage 10, the air i15 generated by the rotation of the radiator 12 exchanges heat with the heat radiating member 21, absorbs the heat of the heat radiating member 21, and is heated. The heat radiation member 21 is cooled. The heated air flow 15 is connected to one end 1 of the air passage 10.
6 and the opening 22, and is used for heating the room, for example.

In the specific example described above, external air is taken in by the fan 12 and this taken-in air is supplied to the air passage 10. However, conversely, air from the air passage 10 is sucked and the sucked air is The fan 12 may be rotated in the opposite direction, or the seven fans 12 may be provided on the side of the opening 22 so as to send out to the outside. There may be three or more.

As described above, according to the present invention, thermal energy is first converted into fertilizing energy using a thermoelectric conversion device, and the blower is driven by this inducing energy, so there is no need for any other power source, and there is no need for electrical wiring, etc. This makes it possible to eliminate the need for heat lice generation, making it possible to create a versatile hot lice generator.
