Connected to the heat exchanger 12 of the bath kettle body 11 and
0 is provided with a pump 13 for forcibly circulating the heat, and a thermoelectric generator 14 that is further heated to generate electric power brings the heat receiving portion 15 on the high temperature side close to the combustion flame of the burner 16 and its tail end portion 17.
In order to cool the cooling water to a lower temperature side, the pump 13 is provided in contact with a bypass water supply passage 18 branched from the circulation water passage 10.
3.

In the above configuration, when the hot water in the bathtub body 9 is springed, when the burner 16 is burned, the burner 16 is heated to hot water by the heat exchanger 12 and the heat receiving portion 15 of the thermoelectric generator 14 is heated by the combustion heat of the burner 16 to a high temperature. Side, and its tail end portion 17 is cooled as a low-temperature side by a branched bypass water passage 18, so that a temperature difference is generated, and the thermoelectric generator 14 generates electric power by the Seebeck effect. And the generated power is wiring 1
At 9, the water was supplied to the pump 13 to drive the pump 13 and circulate the hot water in the bathtub body 9.

[0004]

However, in the conventional apparatus as described above, the pump 1 is driven by the power generation of the thermoelectric generator 14.
3, the power generation efficiency of the thermoelectric generator 14 is determined by the temperature difference between the high-temperature side and the low-temperature side. The temperature due to the combustion of the burner 16 and the temperature of the hot water in the bathtub body 9 are generally several percent or less. And low. In order to generate the driving power of the pump 13 circulated from the bathtub body 9 to the heat exchanger 12 via the circulating water channel 10, a large number of thermoelectric generators 14 are required.

In addition, most of the calorific value of the burner 16 directly heats the element exchanger 12 to heat the hot water flowing into the heat exchanger 12 from the bathtub body 9 via the circulating water channel 10, so that the thermoelectric generator 14 is heated. The amount of generated heat is low, and the generated power is smaller than the driving power of the pump 13 so that the pump cannot be driven.
There is a problem that the circulating flow rate to the heat exchanger 12 via 0 is insufficient. In addition, since the thermoelectric generator 14 is heated near the burner 16 with the heat receiving portion 15 at the high temperature side and heated and cooled at the tail end portion 17 at the low temperature side, it cannot be directly fixed to the circulating water channel 10 due to position restrictions. Since the tail end portion 17 is fixed to the bypass water supply passage 18 which is provided separately from the circulation water passage 10 from the pump 13 for cooling, the configuration becomes complicated. Furthermore, the amount of the thermoelectric generator 14 to be attached is limited due to positional restrictions, and there is also a problem that the generated power is insufficient to drive the pump 13 as described above, or the circulation flow rate of the circulation channel 10 is insufficient. Was.

Then, when the combustion means is burned, the thermoelectric conversion means receives the heat of combustion of the combustion means on the high-temperature side surface and becomes hot. Further, heat is transferred to the heat exchange means. The thermoelectric converter generates electric power according to the temperature difference between the high temperature side and the low temperature side. The power storage means stores power generated by the thermoelectric conversion means. The storage / discharge control means discharges when the storage of the storage means reaches a predetermined value, and drives the heat medium forced circulation means.

The power storage means stores the power generated by the thermoelectric conversion means, and the storage / discharge control means discharges the power when the power stored in the power storage means reaches a predetermined value to drive the heat medium forced circulation means. There is no need to constantly generate power equivalent to the drive power of the means, and the thermoelectric conversion means may be small and small. Further, even if the amount of combustion heat of the combustion means fluctuates and the generated power fluctuates in a direction in which the generated electric power decreases, the heat medium forced circulation means can be driven.

Further, the thermoelectric conversion means receives most of the combustion heat of the combustion means on the high-temperature side, transfers the heat from the low-temperature side to the heat exchange means, heats the heat medium, and generates power at the same time. Compared to a configuration in which the part directly heats the heat exchanger and exchanges heat with hot water, a smaller percentage of the amount of heat heats the thermoelectric generator, so the generated power is smaller and the pump cannot be driven, or the circulation flow rate may be insufficient. Therefore, the heat medium forced circulation means can be reliably driven.

The storage / discharge control means controls the driving means. The heat medium forced circulation means conveys the heat medium to the heat exchange means, causes the transmitted heat of the combustion means to exchange heat with the heat medium, then circulates to the heat radiating means to radiate heat, further returns to the heat medium forced circulation means, Heat transfer is performed. When the power generated by the thermoelectric conversion means decreases to a predetermined value or less, control is performed again to drive the heat medium forced circulation means by using both the power generated by the thermoelectric conversion element means and the power of the battery. Thereafter, the operation is repeated by repeating this operation. Until the electric power generated by the thermoelectric conversion element means reaches a predetermined value, the heating medium forced circulation means is driven by the combined use of the electric power generated by the thermoelectric conversion element means and the electric power of the battery to generate the thermoelectric conversion element means. When the power reaches the predetermined value, the power generated by the thermoelectric conversion element means is discharged alone to drive the heat medium forced circulation means, so that there is no need to constantly generate power equivalent to the drive power of the heat medium forced circulation means.

Alternatively, the power generated by the thermoelectric converter 20 or the power of the battery 5 is directly supplied to the heat medium forced circulation unit 4. The boosting means 25 boosts these powers and raises them to a drive voltage or higher for the heat medium forced circulation means 4 which requires a drive voltage higher than the voltage of the power generated by the thermoelectric conversion element means 20 or the voltage of the battery 5. This enables driving. The heat medium forced circulation means 4 conveys the heat medium to the heat exchange means 3, exchanges the transmitted heat of the combustion means 2 with the heat medium, and then circulates the heat to the heat radiating means 8 to radiate heat. Returning to the means 4, heat transfer is performed. In general, the power generated by the thermoelectric conversion means 20 is several volts or less, but it can be driven even if it is lower than the drive voltage of the heat medium forced circulation means 4.

As described above, according to the present invention, the following effects can be obtained.

(1) The power storage means stores the power generated by the thermoelectric conversion means, and the storage / discharge control means discharges the power when the power stored in the power storage means reaches a predetermined value to drive the heat medium forced circulation means. There is no need to constantly generate power equivalent to the driving power of the forced circulation means, and the thermoelectric conversion means has the advantageous effect of being small and small in size. Further, there is an advantageous effect that the heat medium forced circulation means can be driven even when the amount of combustion heat of the combustion means fluctuates and the generated electric power fluctuates in a direction in which the generated electric power decreases.

(2) The power storage means stores the power generated by the thermoelectric conversion means, and the storage / discharge control means discharges the power when the power stored in the power storage means reaches a predetermined value to drive the heat medium forced circulation means. There is no need to constantly generate power equivalent to the driving power of the forced circulation means, and the thermoelectric conversion means has the advantageous effect of being small and small in size. Further, there is an advantageous effect that the heat medium forced circulation means can be driven even when the amount of combustion heat of the combustion means fluctuates and the generated electric power fluctuates in a direction in which the generated electric power decreases. Further, the thermoelectric conversion means receives most of the combustion heat of the combustion means on the high-temperature side, transfers the heat from the low-temperature side to the heat exchange means, heats the heat medium, and generates power at the same time. Compared to a configuration in which the part directly heats the heat exchanger and exchanges heat with hot water, a smaller percentage of the amount of heat heats the thermoelectric generator, so the generated power is smaller and the pump cannot be driven, or the circulation flow rate may be insufficient. Therefore, the heat medium forced circulation means can be reliably driven. Due to the location restrictions, there is no need to provide a bypass water channel separate from the circulating water channel, the configuration is simplified, and thermoelectric conversion means that only generates large power can be attached. It has an advantageous effect that it can be driven.

(3) The power storage means stores the generated power, and until the power reaches the predetermined value, the power of the battery is energized to drive the heating medium forced circulation means. When the power storage of the power storage means reaches the predetermined value, the battery is charged. Since the power supply of the thermoelectric conversion element is stopped and the stored power generated by the thermoelectric conversion element is discharged, there is no need to constantly generate power equivalent to the drive power of the heat medium forced circulation means, and the thermoelectric conversion means requires a small amount. It has the advantageous effect of being small in size.
Further, there is an advantageous effect that the heat medium forced circulation means can be driven even when the amount of combustion heat of the combustion means fluctuates and the generated electric power fluctuates in a direction in which the generated electric power decreases. Then, the heat medium forced circulation means can be driven by the battery immediately after the start of operation, and this has an advantageous effect that heat transfer is performed efficiently. Compared to a conventional case in which the heat medium forced circulation means is driven only by a battery, the frequency and labor for battery replacement are reduced, and the cost of the battery is reduced, which is economical. The heat medium forced circulation means can be driven by the battery immediately after the start of operation, and has an advantageous effect that heat transfer is efficiently performed.

(4) Until the electric power generated by the thermoelectric conversion element means reaches a predetermined value, the heat medium forced circulation means is driven by the combined use of the electric power generated by the thermoelectric conversion element means and the electric power of the battery. When the power generated by the heating element reaches a predetermined value, the power generated by the thermoelectric conversion element is discharged alone to drive the forced heat medium circulating means. There is no need to perform the process, and the thermoelectric conversion means has an advantageous effect that a small amount and small size are sufficient. Further, there is an advantageous effect that the heat medium forced circulation means can be driven even when the amount of combustion heat of the combustion means fluctuates and the generated electric power fluctuates in a direction in which the generated electric power decreases. Then, the heat medium forced circulation means can be driven by the battery immediately after the start of operation, and this has an advantageous effect that heat transfer is performed efficiently. Compared to the conventional case in which the heat medium forced circulation means is driven only by the battery, the frequency and time required for battery replacement are reduced, and the cost of the battery is reduced, which is advantageous in that it is economical. The heat medium forced circulation means can be driven by the battery immediately from the operation start,
There is an advantageous effect that heat transfer is performed efficiently.

(5) A step-up means is provided in the circuit for energizing the heat medium forced circulation means, and the heat medium forced circulation means requires a drive voltage higher than the voltage of the power generated by the thermoelectric conversion element means.
Driving is enabled by boosting to a driving voltage or higher. In general, the generated electric power of the thermoelectric conversion means is several volts or less, but has an advantageous effect that it can be driven even if it is lower than the drive voltage of the heat medium forced circulation means.
