【Example】
An embodiment of the present invention will be described below with reference to the drawings.
[0021]
Example 1
FIG. 1 shows an overall configuration diagram of a reheating hot water supply apparatus according to Embodiment 1 of the present invention. Reference numeral 9 denotes a main body case of the hot water supply apparatus . 10 is a burner for heating the heat exchanger 12, 11 is a burner fan for sending combustion air to the burner 12, 13 is an exhaust port for combustion gas, 14 is a hot water supply circuit, and water entered from the hot water inlet 15 is the heat exchanger 12. It is heated and discharged from the currant 17 or the like via the hot water supply outlet 16. 18 is a bath pump provided in the recirculation circuit 20, and the circulating water in the recirculation circuit 20 is heated by the heat exchanger 12 through the pipe 19 and then mixed in the recirculation circuit 20. At 27, oxygen-enriched air is mixed. In this case, by using a structure that pulls air by providing a throttle for circulating water, such as an ejector, as the mixing means 27, a large amount of air is introduced if a negative pressure is generated in the flow and oxygen-enriched air is mixed. Can be effective. In this case, not only oxygen-enriched air but also normal air is effective. Here, it is characterized in that oxygen-enriched air is mixed into the circulating water after being heated, and if mixed before being heated, abnormal noise occurs while passing through the heat exchanger 12, This is because corrosion of the heat exchanger 12 may be accelerated.
[0022]
Reference numeral 21 denotes a bathtub, and reference numeral 22 denotes a reheating adapter that discharges bathtub water circulated during a normal reheating operation. 23 is an oxygen-enriched membrane, 24 is a vacuum pump for depressurizing air and passing air between the oxygen-enriched membranes to obtain high oxygen concentration air, and 25 is for sending fresh air to the oxygen-enriched membrane It is a blower fan, and this oxygen-enriched film 23, vacuum pump 24, and blower fan 25 constitute an oxygen enrichment device 26. In addition, since the vacuum pump 24 is disposed downstream of the oxygen-enriched film 23, the thin film of the oxygen-enriching device 26 serves as a filter, and there is no risk of the vacuum pump 24 becoming clogged with dust. No filter is required.
[0023]
The operation and action of the hot water supply device with a reheating function configured as described above will be described below.
[0024]
The mixing means 27 mixes high-concentration oxygen from the oxygen enricher 26 into hot water or water in the reheating circuit 20, and the hot water or water mixed with oxygen from the reheating adapter 22 attached to the bathtub 21. When jetting, high-concentration oxygen becomes bubbles 28 and passes through the bath water, and then fills the bathroom. As a result, the person taking a bath can use the hot water while sucking high-concentration oxygen, thereby promoting the warm bath effect and preventing a nap. In addition, it can be expected that oxygen dissolves in the bath water to suppress generation of germs and reduce sliminess and odor. And if it is this structure, in order to utilize the reheating circuit which a water heater has, since the gas mixing apparatus containing the oxygen enrichment apparatus 26 is stored in the main body case 9, an unnecessary space is also unnecessary and inexpensively. Since it can be created, it can also be installed in ordinary households.
[0025]
Further, as shown in FIG. 2, a louver 30 (29 is a louver for sucking in combustion air) is provided in the main body case 9 of the hot water supply device as air supply means, and the air sucked from the louver 30 is the oxygen-rich material. It is configured to be supplied to the chemical film 23, and air is sucked from the gallery 30 opened for the oxygen-enriched film 23 using the suction pressure of the combustion fan 11 of the hot water heater, and the air is enriched with oxygen. The fresh air of the film 23 is used. This eliminates the need for a dedicated fan for the oxygen-enriched film and allows a simpler configuration.
[0026]
Further, as a configuration of the mixing means 27 for mixing a gas such as high-concentration oxygen into the recirculation circuit 20, high-concentration oxygen is mixed from the oxygen-enriched film 23 using the negative pressure generated by the restrictor of the ejector. By adopting the configuration, the amount of mixed air is reduced, but the vacuum pump 24 is not required and a movable part is not required, so that a very simple configuration can be achieved.
[0027]
FIG. 3 shows an example of the oxygen enriched film 23. A thin film 32 is attached to the surface of the frame 31, and fresh air 33 is taken out as air 34 with an increased oxygen concentration by passing between the thin films 32 by pressurization or decompression means. Stable performance can be obtained with a simple configuration. Reference numeral 35 denotes air remaining after the oxygen is extracted, and this is released into the atmosphere.
[0028]
Next, a hot water supply device with a reheating function according to a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. Since the overall configuration is the same as that of the first embodiment, description thereof is omitted.
[0029]

It is A sectional drawing. The swivel mechanism 37 has two inclined plates 38 and 39 arranged in opposite directions, so that the flow flows along the inner wall surface of the passage to form a swirl flow. As shown in FIG. 6, the flow velocity of the swirling flow increases at the nozzle throttle 40, and the bubbles mixed in the water at this time are subdivided, and the bubbles come out from the ejection nozzle 36. The noise generated when going is reduced, the buoyancy of the bubbles is reduced and the lift is delayed, and the bubbles can reach far and spread over the entire bathtub. In addition, the water or hot water 41 coming out of the jet nozzle 36 goes out while swirling, so that even when hot hot water is jetted, the heat is dispersed and does not become hot, and there is no concern about burns.
[0030]
Next, a hot water supply device with a reheating function according to a third embodiment of the present invention will be described with reference to FIGS. 6 and 7. Since the overall configuration is the same as that of the first embodiment, description thereof is omitted.
[0031]
The third embodiment shows another turning mechanism. FIG. 6 is a cross-sectional view of the tracking adapter 22, and FIG. 7 is a cross-sectional view taken along the line AA of FIG. As the turning mechanism 42, the passage diameter of the passage 43 communicating with the ejection nozzle 36 in the bathtub water discharge section from the recirculation circuit 20 is enlarged, and the direction deflected in the circumferential direction substantially perpendicular to the flow with respect to the enlarged portion. By providing the jet outlets 44 and 45 for jetting the jets, the flows 46 and 47 generated from the jet outlets collide with the enlarged passage 43 to be swirled like 48 and 49. The swirling flow is increased in flow velocity at the nozzle restricting portion 40 and exits while swirling like 41.

Thus, the flow is deflected in the circumferential direction, and a swirl flow can be created more efficiently.
[0034]
Further, as shown in FIG. 10, the number of jets of the jet in the turning mechanism is set to three, 58, 59, 60, and the change promotion unit 61 is also set to three legs as shown in the figure, so that the three jets are balanced. It is possible to balance and create the most stable swirl flow.
