Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a thermoelectric generator device in a heater.

Conventionally, when attaching a thermoelectric generating element device to a heater, it is common to attach a thermoelectric generating element C within a combustion surface B of a gas burner main body A as shown in FIG. 1, for example. However, with this installation method, the radiation area is reduced by the mounting area of the thermoelectric generator, and the wiring part of the thermoelectric generator must be completely sealed to prevent gas leakage, making the structure complicated and complicated. It has the disadvantage of becoming Another drawback is that the temperature rise on the combustion surface is slow.

Note that the "thermal power generation element" referred to here is, for example, a special P-type semiconductor and an N-type semiconductor that are joined at their tips to form a heating section, and a connection between the heating section and the sink section is made from a sink section at the tail end. A device that extracts a relatively large thermoelectromotive force according to the temperature difference has been developed. This thermoelectric power generating element generates a thermoelectromotive force at the output terminal, which is 200mV to 300mV, which is larger than the thermoelectromotive force of 20mV generated by a conventional thermocouple, and has good durability and heat resistance. There are high expectations for its use as it has various excellent performances such as high conversion efficiency and low cost in converting energy from energy to electrical energy. It is being considered to be used as a power source for blowers.

The present invention arranges such a thermoelectric generating element between a lower burner and an upper burner, and makes the heating part of the thermoelectric generating element protrude beyond the combustion surface of the burner, and the sink part is located within the heater main body. By installing it so that it protrudes into the air circulation path formed on the back side,
This product was designed to eliminate all the drawbacks of conventional products.

The present invention will be described in more detail below with reference to preferred embodiments shown in the drawings.

FIG. 2 is a front view of a heater embodying the present invention, and FIG. 3 is a longitudinal side view thereof.

In the figure, 1 is the main body of the heater, 2 and 3 are burners fixed vertically in parallel within the main body 1 of the heater, and the lower burner 2 is a constant fire type, and the upper burner 3 is a burner according to the room temperature. It is a flashing type that blinks. The burners 2 and 3 are both radiation type burners whose combustion surfaces 4 and 5 serve as radiation surfaces.

A thermoelectric generating element 6 is installed between the upper and lower burners 2 and 3. Furthermore, if the lower burners 2 and 3 are horizontally long, this thermoelectric power generating element 6
A plurality of burners are installed parallel to the upper and lower burners 2 and 3 at required intervals. Moreover, the thermoelectric generating element 6 connects the heating section 7 to the combustion surfaces 4, 4, and 4 of the upper and lower burners 2, 3, respectively.
While the sink part 8 is made to protrude beyond the heater body 5, the sink part 8 is attached so as to protrude into an air circulation path 9 formed on the back side of the heater main body 1. Sho 1
0 is an air circulation fan, and 11 is a hot air outlet.

In the present invention, as described above, the heating part 7 of the thermoelectric generating element 6 is made to protrude beyond the combustion surfaces 4 and 5 of the upper and lower burners 2 and 3, so that it is heated by the combustion exhaust and is heated from the combustion surfaces 4 and 5. The heat generating element 6 becomes red hot first, and therefore the slow temperature rise on the combustion surface, which is a drawback of the conventional structure, can be solved and the temperature rise can be accelerated. Unlike the conventional structure in which it is attached, since it is attached to the middle part of the upper and lower burners 2 and 3, the radiation area corresponding to the installation area of the thermoelectric generating element is not reduced as in the conventional case, and the radiation area is reduced by the red-hot area of the heating section 7. can be effectively used as a radiation surface.

On the other hand, since the sink part 8 of the thermoelectric generating element 6 protrudes into the air circulation path 9, the cooling effect is large.
Therefore, the temperature difference between the heating section 7 and the sink section 8 increases, and the thermoelectromotive force can be further increased. The electromotive force generated by this thermoelectric power generation element 6 can be used as a power source for operating the air circulation fan 10 or a combustion control device (not shown), and is of great practical use.
