When the electrode 120 of the material described below is used, such as the above-described ion aqueous solution, the reaction is not only stably made even after the electric arc is generated, and damage of the electrode 12 does not occur. However, if the PH range is smaller than the above-mentioned standard, the electric resistance reaction is weak and no electric arc occurs. If the PH range is larger than this, the electric resistance reaction is explosive at the commercial power supply (220V, 380V), causing melting or burning of the electrode 12. Will occur.

That is, 2n (n is an integer of 1 or more) electrodes 12 are provided in the case of a single phase power supply, and 3n (n is an integer of 1 or more) electrodes are provided in the case of a three phase power supply.

In addition, since the electrode 12 is not necessarily installed through the upper surface of the reaction tank 11, it may be installed through the side portion of the reaction tank (11). An insulating fixing member such as rubber packing should be installed at the boundary between the electrode rod 12 and the reaction tank 11. In particular, in the case of using the metal reaction tank 11, of course, the electrode rod 12 should be installed so as not to contact the reaction tank (11).

The end of the electrode 12 exposed to the outside of the reaction tank 10 is formed with a connection terminal 13 for connecting the power. The power applied to the connection terminal 13 may be commercial AC power or DC.

Hereinafter, the operation of the hot water heater 100 according to the first embodiment of the present invention will be described with reference to the flowchart of FIG. 3 and FIGS. 1 and 2.

First, the aqueous solution 14 of the above-described component is filled in the reaction tank 11, and when the user presses an operation switch (not shown) of the hot water heater, power is supplied to each electrode 12, and the aqueous solution 14 having conductivity is The temperature of the aqueous solution 14 gradually rises while generating resistance heat. The amount of current applied in this process also increases gradually. (ST11, ST12)

However, when the aqueous solution 20 of the above-described component is heated to about 80 ° C., an electric arc is generated between the electrodes 14, and thus, the flame ball is formed inside the aqueous solution 14 as shown in FIG. 4. (火焰 球) occurs.

In particular, power consumption begins to decrease after the arc occurs.

That is, in the process of raising the aqueous solution 14 stored in the reaction tank 11 having the capacity as shown in FIG. 4 from room temperature to about 80 ° C., the current consumption increased from about 10A to about 50A, but after the arc occurred, As it gradually decreases, the boiling point of the aqueous solution 14 was found to be lowered to a level of about 10A.

Therefore, when the electric arc reactor 10 is used for generating hot water as in the first embodiment of the present invention, the target temperature of the aqueous solution 14 may be set at a level of about 95 ° C to 99 ° C, which is just before boiling. . According to the conventional method using the electrode, there is no phenomenon that the amount of current decreases because no arc occurs even after heating for a long time. (ST13, ST14)

When the aqueous solution of the reaction tank 11 reaches the target temperature, the controller 30 operates the pump P1 and the blower 110. The high temperature aqueous solution pumped through the outlet pipe 17 is cooled while passing through the heat exchanger 120 and then recovered to the reaction tank 11 through the recovery pipe 19. In this process, the heated air while passing through the heat exchanger 120 is sent out through the blower pipe 150. (ST15)

If it is set to heat the water stored in the heat storage tank 200 to a target temperature, the controller 30 controls the pump P2 by feeding back a detection result of a temperature sensor (not shown) installed in the heat storage tank 200. . That is, when the hot water of the heat storage tank 200 is below the target temperature, the pump P2 is operated to heat the water stored in the heat storage tank 200, and when the target temperature is reached, the operation of the pump P2 is stopped.

According to the experiment, the heat storage tank 200 was filled with 571 liters of cold water at about 14 ° C., and the 380V commercial power supply (R, S, T) was connected to the three electrode rods 12 of the electric arc reactor 10 to supply power. When supplied, the water in the heat storage tank 200 is heated to 82 ℃ in about 60 minutes, through which the hot water heater 100 of the present invention can confirm that a large amount of hot air and hot water can be generated at the same time have. (ST16)

However, the hot water warmer 100 according to the second embodiment of the present invention includes a steam supply pipe 21 for supplying steam to the heat exchanger 120 and a condensate recovery pipe 22 for recovering condensed water to the reaction tank 11. There is a difference in the connection points.

The condensate return pipe 22 is provided with a pump P3 for pumping the condensate into the reaction tank 11. Instead of connecting the condensate return pipe 22 directly to the reaction tank 11, the condensate return pipe 22 may be connected to an aqueous solution storage tank (40 of FIG. 6) installed to replenish the aqueous solution with the reaction tank 11. .

On the other hand, it is preferable that a trap 130 for temporarily storing condensed water is installed at the outlet of the heat exchanger 22, and the condensed water return pipe 22 is connected to the trap 130. In this case, the trap 130 may be provided with a predetermined level sensor to set the controller 30 to operate the pump P3 when the condensate reaches a predetermined level.

In the second embodiment, high temperature steam is generated inside the reaction tank 11, and the generated steam is moved to the heat exchanger 120 by its own pressure. However, since the high-pressure steam is generated and discharged to the outside, the configuration of the electric arc reactor 10 may be somewhat complicated as compared with the case of simply producing and circulating hot water.

The liquid return pipe 61 is preferably provided with a check valve for preventing backflow.

The pressure feedback pipe 62 serves to equalize the internal pressure of the water level control tank 50 and the reaction tank 11, and thus, the water level inside the reaction tank 11 is adjusted through the water level of the water level control tank 50. It can be confirmed indirectly. The water level sensor 51 is installed in the water level control tank 50, and the controller 30 feeds back the detection result of the water level sensor 51 to control the pump P4 to replenish the aqueous solution into the reaction tank 11. can do.

The aqueous solution stored in the aqueous solution storage tank 40 is supplied to the inside of the reaction tank 11 through the pump (P4), to prevent the backflow to the aqueous solution supplement pipe (16) connecting the pump (P4) and the reaction tank (11) It is preferable that a check valve 98 is provided. In addition, the pipe connecting the pump (P4) and the aqueous solution storage tank 40 can be installed a strainer (99) for removing foreign matter.

The liquid recovery tube 61, the pressure feedback tube 62, the aqueous solution supplement tube 16 and the like are preferably used as a flexible hose, but is not necessarily limited thereto.

In order to use the hot water heater 100 according to the second embodiment, the target temperature of the aqueous solution set in the controller 30 must be equal to or higher than the boiling point. Therefore, when the user turns on the operation switch (ON), after the aqueous solution reaches about 80 ° C an electric arc is generated in the reaction tank 11, and then the aqueous solution boils and generates a large amount of steam.

The generated steam is supplied to the heat exchanger 120 via the steam supply pipe 21, condensed while passing through the heat exchanger 120, and stored in the trap 130.

The controller 30 feeds back the detection result of the pressure sensor or the temperature sensor installed in the reaction tank 11 to operate the blower 110 when the set pressure or temperature is reached. By installing a temperature sensor or the like on the heat exchanger 120, the blower 110 may be controlled by feeding back a detection result thereof. Therefore, the air heated while passing through the heat exchanger 120 is sent out through the blower pipe 150.

In addition, when the condensed water generated while passing through the heat exchanger 120 is filled in the trap 130 to a predetermined level or more, the pump P3 is operated to recover the condensed water to the reaction tank 11 or the aqueous solution storage tank 40.
