【Example】
(Example 1)
FIG. 1 shows an overall configuration diagram of an oxygen-enriched hot water supply apparatus according to a first embodiment of the present invention. 9 is a water heater main body. 10 is a burner for heating the heat exchanger 12, 11 is a burner fan for sending combustion air to the burner 10, 13 is an exhaust port for combustion air, 14 is a hot water supply circuit, and water entering from a hot water supply inlet 15 is supplied to the heat exchanger 12. It is heated and exits from hot water supply outlet 16 and is discharged from curran 17 and the like. Reference numeral 18 denotes a bath pump provided in the reheating circuit 19, and circulating water discharged from the bath is heated by the heat exchanger 12, and then mixed with oxygen-enriched air by mixing means 27. In this case, by using a configuration in which a throttle for circulating water such as an ejector is provided as a mixing means and air is sucked, a large amount of air can be introduced if a negative pressure is generated in the flow and oxygen-enriched air is mixed. Can be effective. Also, it is possible to mix the circulating water with the pressure of the vacuum pump without using a throttle. In this case, the effect is slightly reduced, but the configuration of the throttle section is unnecessary and the configuration is simplified.
[0015]
Here, the reason why the oxygen-enriched air is mixed after the heating is that if the air is mixed before the heating, an abnormal sound is generated while passing through the heat exchanger 12 or the corrosion of the heat exchanger 12 is promoted. This is because there is a risk of 20 is a bathtub and 21 is a reheating adapter. 22 is an oxygen-enriched membrane, 23 is a vacuum pump for depressurizing air and passing air between the oxygen-enriched membranes to obtain air with a high oxygen concentration, and 24 is for sending fresh air to the oxygen-enriched membrane. It is a blower fan, and the oxygen enrichment device 25 is constituted by three of these 22, 23 and 24.
[0016]
Since the vacuum pump 23 is disposed downstream of the oxygen-enriched membrane, the thin membrane of the oxygen-enriching device functions as a filter, and there is no possibility that the vacuum pump 23 is clogged with dust. It is. Reference numeral 26 denotes a fragrance supply means, which has a pipe coming out of a case for containing the fragrance, and is connected to the upstream of the vacuum pump 23 by this pipe.
[0017]
The operation and operation of the oxygen-enriched hot water supply apparatus configured as described above will be described below. Due to the negative pressure of the vacuum pump 23, the vaporized fragrance in the fragrance supply means 26 is mixed with high-concentration oxygen coming out of the oxygen-enriched film 22. The high-concentration oxygen with fragrance from the oxygen enrichment device 25 is mixed into the hot water or water in the reheating circuit 19 by the mixing means 27, and the hot water or water mixed with the fragrance-containing oxygen is supplied to the bathtub 20. When spouting from the attached reheating adapter 21, oxygen with a high concentration of fragrance becomes bubbles 28, passes through the bathtub water, and then fills the bathroom.
[0018]
As a result, the person who is taking a bath can get into the hot water while absorbing high-concentration aromatic oxygen, thereby promoting the warm bath effect and preventing falling asleep. In addition, the effect of aromatherapy can be expected by filling the bathroom with a favorite aroma. Furthermore, it is expected that the dissolution of oxygen into the bathtub water suppresses the generation of various germs and reduces sliminess and odor. In addition, according to this configuration, since it can be accommodated in the casing 9 of the water heater, no extra space is required, and it can be produced at low cost, so that it can be installed in a general household.
[0019]
