  Hereinafter, embodiments of the present invention will be described in detail. First, the hot air generator 100 which concerns on embodiment of this invention is demonstrated with reference to drawings.

  As shown in FIGS. 1 and 2, the hot air generator 100 according to the embodiment of the present invention includes a combustion unit 110, a thermoelectric conversion element 120 in which a high temperature surface 122 is thermally joined to the combustion unit 110, a thermoelectric device, and the like.

In addition, the front-back direction of the hot air generator 100 is as shown in FIG. Further, as shown in FIG. 2, a cover 160 having an opening at the front is attached so as to cover substantially the entire side and back of the hot air generator 100, and a radiator is provided on the back of the hot air generator 100. An air inlet 162 for 131 is formed.

  As shown in FIGS. 1 and 2, the combustion unit 110 has a burner 112 that generates a flame, an ignition device 114 that ignites the burner 112, and an opening in the front, and covers the flame from the burner 112 from the side. And a burner cover 116. As will be described later, the ignition device 114 is electrically connected to the storage battery 150 and operates by receiving power from the storage battery 150. A fuel tank 118 is connected to the combustion unit 110, and the burner 112 can generate a flame with liquid fuel (for example, kerosene) supplied from the fuel tank 118 by a pump 119. The pump 119 is electrically connected to the storage battery 150 and operates by receiving power supply from the storage battery 150. The burner 112 injects a flame forward in the burner cover 116. The heat generated in the combustion unit 110 is sent to the front of the hot air generator 100 by air sent from a blower unit 140 described later. Thus, the combustion unit 110 can send out hot air toward the front of the hot air generator 100.

  The thermoelectric conversion element 120 is an element that combines a p-type thermoelectric material and an n-type thermoelectric material. The thermoelectric conversion element 120 includes a high temperature surface 122 and a low temperature surface 124, and is an element that generates electric power by a temperature difference between the high temperature surface 122 and the low temperature surface 124. Note that the power generation efficiency improves as the temperature difference between the high temperature surface 122 and the low temperature surface 124 of the thermoelectric conversion element 120 increases. The high temperature surface 122 is thermally joined to the burner cover 116 of the combustion unit 110, and is heated by the heat of the flame generated from the burner 112, thereby raising the temperature of the high temperature surface 122. On the other hand, as will be described later, the low temperature surface 124 is thermally joined to the first pipe 132 and the second pipe 134 of the cooling unit 130, and is cooled by water flowing in the first pipe 132, The temperature of the low temperature surface 124 is lowered.

  The cooling unit 130 includes a radiator 131, an inner pipe 138 that passes through the radiator 131, a first pipe 132 that thermally connects the low temperature surface 124 of the thermoelectric conversion element 120 to the inner pipe 138, and an inner pipe that extends from the low temperature surface 124. A second pipe 134 that thermally connects 138, and a pump 136 connected to the first pipe 132. The pump 136 is electrically connected to the storage battery 150 and operates by receiving power from the storage battery 150. As described above, the first tube 132 and the second tube 134 are thermally bonded to the low temperature surface 124 of the thermoelectric conversion element 120. In the cooling unit 130, water (circulating liquid) is circulated. More specifically, water flows in the first tube 132, the second tube 134, and the inner tube 138, and the water circulates in the direction indicated by the arrows in FIGS. The water flowing in the first pipe 132 reaches a region near the low temperature surface 124 and cools the low temperature surface 124. The water that has cooled the low-temperature surface 124 flows into the second pipe 134 in a state where the temperature is high. Water flowing in the second pipe 134 enters the inner pipe 138 of the radiator 131. The hot water flowing in the inner pipe 138 is cooled by the radiator 131 and flows into the first pipe 132 in a state where the temperature is lowered. The low-temperature water flowing in the first pipe 132 reaches the region near the low-temperature surface 124 by the pump 136 and cools the low-temperature surface 124. Thus, by circulating water in the first tube 132, the second tube 134, and the inner tube 138, the low-temperature surface 124 of the thermoelectric conversion element 120 can be efficiently cooled by low-temperature water. By efficiently cooling the low temperature surface 124 by the cooling unit 130, the temperature difference between the high temperature surface 122 and the low temperature surface 124 of the thermoelectric conversion element 120 becomes large, and the power generation efficiency is improved.

  As shown in FIG. 2, the air blowing unit 140 is provided behind the radiator 131 and sends air in the direction of the arrow in FIG. 1. The air blowing unit 140 plays a role of sending warm air toward the front of the hot air generating device 100 by sending air to the combustion unit 110, and sending air to the radiator 131 of the cooling unit 130, The cooling efficiency is improved, and the heat stored in the radiator 131 is also sent to the combustion unit 110. About the latter, more specifically, the heat generated by the radiator 131 can be enhanced by applying the wind generated from the air blowing unit 140 to the radiator 131, and the temperature of the water flowing in the inner pipe 138 can be lowered efficiently. Can do. As a result, the temperature of the water flowing in the first pipe 132 can be further lowered, and the low temperature surface 124 of the thermoelectric conversion element 120 can be cooled more efficiently. Further, the radiator 131 stores heat due to depriving heat from the water flowing in the inner pipe 138. By sending air from the blower 140 to the radiator 131, the heat stored in the radiator 131 is stored in the combustion section. 110, the temperature in the burner cover 116 rises, whereby the temperature of the hot surface 122 of the thermoelectric conversion element 120 can be further increased. As a result, the temperature difference between the high temperature surface 122 and the low temperature surface 124 of the thermoelectric conversion element 120 can be increased, and the power generation efficiency can be further improved. Note that the air blowing unit 140 is electrically connected to the storage battery 150 and operates by receiving power from the storage battery 150.

  The storage battery 150 is electrically connected to the thermoelectric conversion element 120 and plays a role of storing the electric power generated by the thermoelectric conversion element 120. The storage battery 150 is electrically connected to the ignition device 114 and the pump 119 of the combustion unit 110, the air blowing unit 140, and the pump 136 of the cooling unit 130, and supplies power thereto. At the initial operation of the hot air generator 100, the ignition device 114, the pump 119, the air blower 140, and the pump 136 are driven by the electric power previously stored in the storage battery 150. When the electric power generated by the thermoelectric conversion element 120 exceeds the used electric power, the electric power is supplied independently. In the present embodiment, the power generated by the thermoelectric conversion element 120 is DC power, which is input to the storage battery 150 as DC power and output from the storage battery 150 as DC power. The ignition device 114 operates with AC power converted by an inverter (not shown). The pump 119, the air blowing unit 140, and the pump 136 operate with DC power from the storage battery 150.

  Operation | movement of the warm air generator 100 which concerns on embodiment of this invention is demonstrated. The ignition device 114 and the pump 119 operate by receiving power supply from the storage battery 150, and the burner 112 generates a flame by the liquid fuel supplied from the fuel tank 118, and the combustion unit 110 burns. As the combustion unit 110 burns, the temperature of the high temperature surface 122 of the thermoelectric conversion element 120 increases. The air blowing unit 140 receives supply of electric power from the storage battery 150, sends air to the combustion unit 110, and sends heat generated in the combustion unit 110 forward as warm air. The air blowing unit 140 also sends air to the radiator 131 of the cooling unit 130 to lower the temperature of the water flowing into the first pipe 132 and cool the low temperature surface 124 of the thermoelectric conversion element 120. The water that has cooled the low temperature surface 124 flows into the inner pipe 138 of the radiator 131 through the second pipe 134, and then flows into the first pipe 132 again. The pump 136 receives the supply of electric power from the storage battery 150 and causes the water flowing in the first pipe 132 to reach the region near the low temperature surface 124. The air blowing unit 140 also sends air to the radiator 131 of the cooling unit 130 to send heat stored in the radiator 131 to the combustion unit 110. The thermoelectric conversion element 120 generates power by the temperature difference between the high temperature surface 122 and the low temperature surface 124 and stores it in the storage battery 150. The pump 119, the air blowing unit 140, and the pump 136 are continuously operated by receiving power from the storage battery 150, and generate hot air toward the front of the hot air generator 100.

  Next, a hot air generation method according to an embodiment of the present invention will be described.

  In the method for generating hot air according to the embodiment of the present invention, the blower 140 (same as above) receives air from the thermoelectric conversion element 120 (same as above) and the air is supplied to the combustion unit 110 (same as above). Generate warm air by sending. The thermoelectric conversion element 120 includes a high temperature surface 122 and a low temperature surface 124, the high temperature surface 122 is thermally bonded to the combustion unit 110, and the low temperature surface 124 is thermally bonded to the cooling unit 130 (same as described above). ing. Further, the air blowing unit 140 cools the cooling unit 130 by sending air to the cooling unit 130. More specifically, the cooling unit 130 includes a radiator 131, and the air blowing unit 140 sends air to the radiator 131 to lower the temperature of the water flowing into the first pipe 132, so that the thermoelectric conversion element 120. The low temperature surface 124 is cooled. The water that has cooled the low temperature surface 124 flows into the inner pipe 138 of the radiator 131 through the second pipe 134, and then flows into the first pipe 132 again. The pump 136 receives the supply of electric power from the storage battery 150 and causes the water flowing in the first pipe 132 to reach the region near the low temperature surface 124. Thus, by circulating water in the first tube 132, the second tube 134, and the inner tube 138, the low-temperature surface 124 of the thermoelectric conversion element 120 can be efficiently cooled by low-temperature water. The air blowing unit 140 also sends air to the radiator 131 of the cooling unit 130 to send heat stored in the radiator 131 to the combustion unit 110. As a result, the temperature difference between the high temperature surface 122 and the low temperature surface 124 of the thermoelectric conversion element 120 is increased, and the power generation efficiency can be further improved.

  As described above, in the hot air generation device 100 and the hot air generation method according to the embodiment of the present invention, the water (circulated liquid) cooled by the radiator 131 efficiently moves the low temperature surface 124 of the thermoelectric conversion element 120. Cooling and the air sent from the air blowing unit 140 cools the cooling unit 130, whereby the low temperature surface 124 can be cooled more efficiently. Further, by sending air from the air blowing unit 140 to the radiator 131, the heat stored in the radiator 131 is sent to the combustion unit 110, and the temperature in the burner cover 116 rises, and thereby the high temperature surface of the thermoelectric conversion element 120. The temperature of 122 can be further increased. As a result, a sufficient temperature difference between the high temperature surface 122 and the low temperature surface 124 of the thermoelectric conversion element 120 can be secured, and power can be stably supplied by the thermoelectric conversion element 120. Therefore, for example, when the hot air generator 100 is used outdoors, when it is used in a disaster, or when it is used at the time of a power failure, it is necessary to prepare a battery or lay an electric wire to secure a power source. And can be used conveniently.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. For example, in the present embodiment, as illustrated in FIG. 1, a mode has been described in which the power generated by the thermoelectric conversion element 120 is stored in the storage battery 150 and the power is supplied. However, as illustrated in FIG. 3, the storage battery 150 and the outlet 154 are connected to the switch 152 (the outlet 154 side is connected via the power adapter 156). At the initial operation, the switch 152 is connected to the outlet 154 side to supply power, and the thermoelectric conversion element 120 stably When the electric power starts to be supplied, the hot air generator 200 may be used by using the switch 152 on the storage battery 150 side.

  In the present embodiment, as shown in FIGS. 1 and 2, the cooling unit 130 includes the radiator 131. However, the cooling includes a mechanism that can sufficiently cool the low-temperature surface 124 of the thermoelectric conversion element 120. If it is the part 130, it may employ | adopt suitably not only in a radiator, but as shown in FIG. 4, you may provide the heat pipe 172 as the cooling part 130, for example. One end side (heat receiving part 174) of the heat pipe 172 is thermally joined to the low temperature surface 124 of the thermoelectric conversion element 120, and the other end side (heat radiating part 176) of the heat pipe 172 is located in front of the air blowing part 140. Has been placed. The heat pipe 172 serves to cool the low temperature surface 124 of the thermoelectric conversion element 120 by transferring heat from the low temperature surface 124 of the thermoelectric conversion element 120 thermally bonded to the heat receiving unit 174 to the heat radiating unit 176 side. . In addition, as shown in FIG. 4, the heat radiation part 176 of the heat pipe 172 may be provided with fins 178 for improving the heat radiation efficiency.

  In the present embodiment, as shown in FIGS. 1 and 2, the embodiment has been described in which a flame is generated from the burner 112 by supplying liquid fuel (for example, kerosene) from the fuel tank 118. The fuel may be a solid fuel (eg, pellets, charcoal, etc.) or a gaseous fuel (eg, butane, isobutane, methane, propane, etc.). In the present embodiment, the pump 119 is used as the fuel supply device. However, in the case of solid fuel, for example, the solid fuel is shaved with a drill and automatically injected into the combustion unit at a desired amount and frequency. A mechanism or the like can be employed.

  In addition, when using gaseous fuel in the above, as shown in FIG. 4, the fuel gas container 182 is connected to the combustion part 110, and gaseous fuel (for example, butane, isobutane, methane, propane, etc.) supplied from the fuel gas container 182 is used. ) May generate a flame. In this case, as shown in FIG. 4, a first pipe 184 and a second pipe 186 are provided around the fuel gas container 182, and the first pipe 184 and the second pipe 186 are connected to the fuel gas container 182 and The thermoelectric conversion element 120 may be thermally bonded to the low temperature surface 124. Water (circulating liquid) flows in the first pipe 184 and the second pipe 186, and water circulates in the direction indicated by the arrow in FIG. The water flowing in the first pipe 184 reaches the region near the low temperature surface 124 of the thermoelectric conversion element 120 and cools the low temperature surface 124. The water that has reached the region in the vicinity of the low temperature surface 124 is given heat from the low temperature surface 124 and flows into the second pipe 186 in a state where the temperature is high. When the water flowing in the second pipe 186 reaches the region in the vicinity of the fuel gas container 182, it heats the fuel gas container 182 and is cooled by the fuel gas container 182 whose temperature has been lowered by the heat of vaporization. In this state, it flows into the first pipe 184. The low-temperature water flowing in the first pipe 184 is in the vicinity of the low-temperature surface 124 of the thermoelectric conversion element 120 by the pump 188 (which is electrically connected to the storage battery 150 and operates by receiving power supply from the storage battery 150). And the low temperature surface 124 is cooled. The water flowing in the second pipe 186 gives heat to the fuel gas container 182 to prevent the temperature of the fuel gas container 182 from being lowered by the heat of vaporization, and the liquid gas in the fuel gas container 182 is vaporized to the end. Therefore, the fuel in the fuel gas container 182 can be used up to the end. As described above, the water is circulated in the first pipe 184 and the second pipe 186 that are thermally joined to the fuel gas container 182, so that the low-temperature water flowing in the first pipe 184 causes the thermoelectric conversion element. The low-temperature surface 124 of 120 can be cooled to improve the power generation efficiency, and the fuel gas container 182 is heated by the water flowing in the second pipe 186, so that the fuel in the fuel gas container 182 is exhausted to the end. Can be used up.

  The second pipe 186 described above, that is, the second pipe 186 whose one end is thermally joined to the low temperature surface 124 of the thermoelectric conversion element 120 and the other end is thermally joined to the fuel gas container 182. Instead, a heat pipe may be used. In this case, the heat pipe is provided so that the heat receiving portion of the heat pipe is thermally joined to the low temperature surface 124 of the thermoelectric conversion element 120 and the heat radiating portion of the heat pipe is thermally joined to the fuel gas container 182. By doing so, heat can be transferred from the low-temperature surface 124 of the thermoelectric conversion element 120 to the heat radiating portion of the heat pipe. Therefore, the low-temperature surface 124 of the thermoelectric conversion element 120 can be cooled and power generation efficiency can be improved. At the same time, heat is applied to the fuel gas container 182 so that the fuel in the fuel gas container 182 can be used up to the end.

  In the present embodiment, as shown in FIGS. 1 and 2, the fuel tank 118 is connected to the combustion unit 110 and the cooling unit 130 includes the radiator 131. However, as shown in FIG. The fuel gas container 182, the first pipe 184, the second pipe 186 and the pump 188 similar to those described above may be provided, and the heat pipe 172 similar to the above may be provided as the cooling unit 130. In this case, the low-temperature surface 124 of the thermoelectric conversion element 120 can be cooled by low-temperature water flowing in the first pipe 184, and the low-temperature surface 124 can also be cooled by the heat pipe 172. As described above, since there are two cooling means for the low temperature surface 124 of the thermoelectric conversion element 120, for example, the pump 188 fails and the low temperature surface 124 cannot be cooled by water flowing in the first pipe 184. Even in this case, the low temperature surface 124 can be continuously cooled by the heat pipe 172. For this reason, the low temperature surface 124 of the thermoelectric conversion element 120 can be cooled more reliably, and more reliable power generation by the thermoelectric conversion element 120 becomes possible.

  When the same fuel gas container 182 and the same heat pipe 172 as described above are employed, both the fuel gas container 182 and the heat pipe 172 are not necessarily provided as shown in FIG. The fuel gas container 182, the first pipe 184, the second pipe 186, and the pump 188 similar to those described above may be provided, and the cooling unit 130 may be provided with the radiator 131. The same heat pipe 172 may be provided, and the fuel tank 118 may be connected to the combustion unit 110.

  In the present embodiment, as shown in FIGS. 1 and 2, a mode in which the cooling unit 130 is cooled by sending air to the cooling unit 130 by the air blowing unit 140 has been described. When the low temperature surface 124 of the conversion element 120 can be sufficiently cooled, it is not necessary to send the air from the air blowing unit 140 to the cooling unit 130. The same applies to the embodiments shown in FIGS.

  In the present embodiment, as shown in FIGS. 1 and 2, the mode in which water (circulating liquid) circulates in the first tube 132, the second tube 134, and the inner tube 138 has been described. The circulating liquid is not limited to water, and for example, an antifreeze liquid may be used. When an antifreeze liquid is used as the circulating liquid, for example, freezing in the first pipe 132, the second pipe 134, the pump 136, and the inner pipe 138 can be prevented when used outside the freezing point. Note that the water (circulating liquid) circulating in the first pipe 132, the second pipe 134, and the inner pipe 138 shown in FIG. 3 and the inside of the first pipe 184 and the second pipe 186 shown in FIG. The same applies to the circulating water (circulating liquid).

  In the present embodiment, as shown in FIGS. 1 and 2, the storage battery 150 supplies power to the ignition device 114 and the pump 119 of the combustion unit 110, the pump 136 of the cooling unit 130, and the air blowing unit 140. In the case where the thermoelectric conversion element 120 can generate electric power exceeding the power used, the storage battery 150 is used for other electric devices (for example, lamps used in disasters, broadcasting devices, etc.). Electric power may be supplied. Further, an outlet is connected to the ignition device 114 and the pump 119 of the combustion unit 110, the pump 136 of the cooling unit 130, and the air blowing unit 140, and all or a part of the power is supplied from the outside, and the thermoelectric power is supplied. You may make it supply the electric power which the conversion element 120 generated to other electric equipments (for example, the lamp | ramp used at the time of a disaster, broadcasting equipment, etc.). The same applies to the embodiments shown in FIGS.

  Further, in the present embodiment, as described above, the embodiment using the thermoelectric conversion element 120 in which the p-type thermoelectric material and the n-type thermoelectric material are combined has been described. As the thermoelectric conversion element, for example, a lead / tellurium system is used. These elements may be used. Any thermoelectric conversion element that exhibits the effects of the present invention can be used as appropriate. The same applies to the embodiments shown in FIGS.

  Moreover, in this embodiment, as shown in FIG. 1 and FIG. 2, the embodiment using one set of thermoelectric conversion elements 120 has been described. However, in view of power consumption, two or more sets of thermoelectric conversion elements are used. Also good. The same applies to the embodiments shown in FIGS.

  Further, in the present embodiment, as shown in FIGS. 1 and 2, the embodiment in which one pump 136 is provided has been described.
