【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0015]
(Example 1)
1 is an overall system configuration diagram of an oxygen-enriched hot water supply apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a configuration diagram when the oxygen-enriched apparatus is installed in the vicinity of a bathtub in a bathroom.
[0016]
The hot water supply apparatus 10 includes a can 2 water heat exchanger 13 having a hot water supply circuit 11 and a recirculation circuit 12, a burner 14 for heating the 1 can 2 water heat exchanger 13, and a burner fan 15 for sending combustion air to the burner 14. And an exhaust port 16 for discharging combustion air. Water in the hot water supply circuit 11 is heated by the heat exchanger 12 and discharged from the currant 17 or the like. The bath water circulated from the bath pump 18 provided in the recirculation circuit 12 is heated in the recirculation circuit 12 of the heat exchanger 13 and then ejected from the reheating adapter 19 to the bathtub 20. An oxygen enrichment device 21 provided, for example, below the apron 32 in the bathroom near the bathtub is an oxygen enrichment film 22, a blower fan 23 as air supply means, a vacuum pump 24 as decompression means, and a mixing means. With the cheese 25 and the check valve 26, oxygen-enriched air having a high concentration from the air in the bathroom is repelled and mixed into the circulation circuit 12.
[0017]
The operation and action of the oxygen-enriched hot water supply apparatus configured as described above will be described below. By reducing the pressure by the vacuum pump 24, the air in the bathroom 28 passes through the oxygen-enriched membrane 22, becomes high-concentration oxygen (about 30%), passes through the check valve 26, and is swept away from the cheese 25 into the circulation circuit 12. Then, the hot water circulated from the reheating adapter 19 is ejected to the bathtub 20. High-concentration oxygen forms bubbles 27 and passes through the bath water, and then diffuses into the bathroom 28. When the oxygen enrichment device 21 is not operated and the reheating operation is performed, the bath water may flow backward to the oxygen enrichment device 21, but the check valve 26 prevents the backflow and protects the oxygen enrichment device 21. As a result, the bather can take a bath while sucking high-concentration oxygen obtained from the air in the bathroom 28, and can exhibit a synergistic effect of relaxation by bathing and high-concentration oxygen inhalation. Furthermore, even in a bathing state in which the chest is slightly compressed by water pressure for whole body bathing, high concentration oxygen can be inhaled, so that it is difficult to fall short of oxygen. Moreover, the awakening effect by oxygen inhalation can be exhibited. On the other hand, when oxygen dissolves in the bath water, the effect of inhibiting the growth of Legionella bacteria, slime, and other bacteria that generate odors, which are anaerobic bacteria, is also exhibited. And since it is the structure which provides the oxygen enrichment apparatus 21 in the recirculation circuit 12, since it is not necessary to provide new piping and it can produce at low cost, while being able to install easily in a general home, high concentration oxygen The temperature drop of the bath water caused by supplying the water can be heated by the chasing operation.
[0018]
Although the example which provided the oxygen enrichment apparatus 21 in the apron 32 lower part here was shown, even if it provides near the bathtub, such as the space which installs the pump for jet baths in the space below a bathtub handrail, the same effect is exhibited.
[0019]
(Example 2)
FIG. 3 is an overall system configuration diagram of an oxygen-enriched hot water supply apparatus according to Embodiment 2 of the present invention, and FIG. 4 is a configuration diagram when the oxygen-enriched apparatus is installed in the vicinity of a bathtub in a bathroom.
[0020]
3 and 4, the difference from the configuration of the first embodiment is that fresh air in the bathroom 28 is supplied to the oxygen-enriched film 22 by the blower fan 23 that is the air supply means of the oxygen-enriching device 21, and the surplus The lead-out part 29 which discharge | releases the high concentration nitrogen air to the exterior of the bathroom 28 is provided. In this way, by discharging the high concentration nitrogen air to the outside of the bathroom 28 by the derivation unit 29, the air inside the bathroom 28 is gradually filled with the high concentration oxygen, and even when in a washing place other than bathing, the relaxation effect by oxygen is enjoyed. It can be done.
[0021]
Example 3
FIG. 5 is a cross-sectional configuration diagram of the mixing means in Embodiment 3 of the present invention. In FIG. 5, the difference from the configuration of Example 1 is that the throttle unit 30 is provided in the cheese 25 of the mixing means, and the high concentration oxygen from the oxygen enricher 21 is guided from the suction unit 31 to the throttle unit 30. It is. After the bath water has passed through the throttle 30, the flow rate rapidly expands and the pressure decreases, and high concentration oxygen can be efficiently mixed from the suction portion 31 by the ejector effect, thereby increasing the amount of high concentration oxygen mixed air. Can be made.
[0022]
Although an example in which high-concentration oxygen is mixed using the vacuum pump 24 and the throttle unit 30 has been shown, even when the vacuum pump 24 is not present, oxygen enrichment can be achieved with a negative pressure due to the ejector effect. Although the concentration and flow rate are reduced, it is possible to achieve a very simple configuration at a low cost and without a vacuum pump.
[0023]
【The invention's effect】
As is clear from the above description, according to the oxygen-enriched hot water supply apparatus of the present invention, oxygen that has been concentrated at the oxygen enrichment apparatus is mixed in the recirculation circuit, so that a pipe to the bathtub is newly installed. Can be created at low cost and can be easily installed in ordinary households. Since the hot water is circulated while heating the high-concentration oxygen and the bath water, the bath water does not cool. Moreover, the synergistic effect of relaxation by bathing and high concentration oxygen inhalation can be exhibited by supplying high concentration oxygen to bath water. Furthermore, even in a bathing state in which the chest is slightly compressed by water pressure for whole body bathing, high concentration oxygen can be inhaled, so that it is difficult to fall short of oxygen. Moreover, the awakening effect by oxygen inhalation can be exhibited. On the other hand, when oxygen dissolves in the bath water, the effect of inhibiting the growth of Legionella bacteria, slime, and other bacteria that generate odors, which are anaerobic bacteria, is also exhibited.
