DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath apparatus for dissolving a gas containing carbon dioxide in hot water to produce hot water containing carbon dioxide.

[0002]

Conventionally this type of bath apparatus had one shown in FIG. Hot water discharged from the hot water supply heat exchanger 2 heated by the gas burner 1 is sprayed from the water spray nozzle 5 through the branch pipe 3 and the electromagnetic valve 4 to the packed bed 7 in the steam-water contact chamber 6. At this time, the hot water flows down along the surface of the packed bed 7,
Carbon dioxide gas in the exhaust gas is dissolved in the hot water. The hot water in which the carbon dioxide gas has been dissolved is supplied from a feed pipe 9 through a three-way switching valve 8 to a bathtub 10.
It is poured into. Thus, the bathtub 10 is filled with hot water containing carbonic acid (for example, Japanese Utility Model Laid-Open No. 5-47).
No. 7499).

[0003]

However, in the above configuration, the hot water sprinkled from the water spray nozzle 5 and the exhaust gas need to be brought into contact with each other over a wide area.
Therefore, there is a problem that the heat source unit becomes large. The present invention solves the above-mentioned problem, and reduces the space at a portion where carbon dioxide in exhaust gas is dissolved in hot water .
In addition, it is intended to improve the dissolution efficiency of carbon dioxide.

[0004]

The present invention SUMMARY OF THE INVENTION To solve the above problems and tubs, the tub heating means for heating the hot water of the bathtub, and forward pipe and the return pipe is the pipe to the bathtub from the heating means, feed water a hot water supply heating means for heating the water from the pipe, a first branch which is branched from an upstream of the hot water supply heating means, first minute branch pipes
An ejector that is kicked set in, and suction means for sucking the exhaust gases of the connected hot water heating unit to the suction portion of the ejector, and undissolved gas separation means of the exhaust gas provided downstream of the ejector, undissolved gas separation means A hot water supply pipe or a return pipe, and a second branch pipe branched from the downstream of the hot water supply heating means and connected to the hot water supply pipe.

[0005]

DETAILED DESCRIPTION OF THE INVENTION The present invention, on the configuration described above, by flowing from the upstream of the hot-water heating means water ejector, since the carbon dioxide in the exhaust gas is easily dissolved than in hot water, to increase the carbon dioxide concentration in the bath You can do it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments corresponding to the present invention will be described with reference to the accompanying drawings. 1, 11 is a bathtub, forward pipe 14 from the heat exchanger 13, the return pipe 15 is a pipe incorporated in the heat source apparatus 12 to the tub 11. The heat exchanger 13 and the burner 16 constitute a bathtub heating means 17 . On the other hand, the heat source apparatus 12 heat交管18 and the burner 1
Hot water heating unit 20 is provided consisting of 9. A thermistor 21 is provided on the discharge side of the heat exchanger 18 .
Downstream of the thermistor 21, a hot water supply pipe 23 is connected to the faucet 22, and a pouring pipe 25 is connected to the going pipe 14 via an on-off valve 24 . On the other hand, from the upstream of the heat exchanger 18 to the ejector 26 , an on-off valve 27 and a vacuum release valve 28
The branch pipe 29 is piped through. Ejector 26
A suction pipe 32 as a suction means is connected to the suction section 30 via an on-off valve 31 . Downstream of the ejector 26 , a separator 33 of undissolved gas discharging means for separating and discharging the undissolved gas of the exhaust gas is provided. Separator 33
A branch pipe 34 is connected to the pouring pipe 25 . 35
Is a water supply pipe, 36 is a thermistor, 37 is a bath remote control, 3
8 is a controller, and 39 is an arrow indicating a flow.

Next, the operation of the present invention will be described. Figure 1
Tub carbon dioxide in the exhaust gas of the heat source apparatus 12 by 11
The operation of dissolving in is described. In this operation, when the bath remote controller 37 in which the amount of hot water to the bathtub 11 , the temperature of hot water and the carbonic acid mode are set is turned on, the on-off valve 27 is opened and the water supply pipe 3 is opened.
The water entering from 5 flows to the ejector 30 via the branch pipe 29 . The water that has entered the ejector 30 flows into the separator 33 as a high-speed flow. At this time, when the on-off valve 31 is opened,
Since the suction portion 30 has a negative pressure due to the suction action of the ejector 26 , part of the exhaust gas of the hot water supply / heating means 20 is sucked into the ejector 30 through the suction pipe 32 . Ejector 3
Inside 0, a high-speed water fluid and exhaust gas flow as a mixed flow. In this case the carbon dioxide in the exhaust gas is dissolved in water, pouring tube 2 from the branch pipe 34 is water containing dissolved carbonate
5 flows. On the other hand, at the time of this operation, the water also flows to the heat exchanger 18 side, and the hot water of the pouring pipe 25 and the water of the branch pipe 34 are mixed, and the temperature of the thermistor 36 is opened and closed so as to become the set temperature of the bath remote controller. The flow rate is adjusted by the valve 24 . Therefore, the outlet temperature of the heat exchanger 18 is high. In the separator 33 , unnecessary exhaust gas that is not dissolved is discharged. When the pouring amount reaches the set amount, the on-off valves 24 and 27 are closed,
The burner 19 , the on-off valves 24 and 27 are turned off, the operation is stopped, and the bathtub 11 is filled with hot water containing carbonic acid.

[0008]

As is clear from the above description, the bath apparatus of the present invention has the following effects. According to the present invention
If the exhaust gas was sucked by the suction action of Eji Ekuta, a structure in which dissolved carbon dioxide in hot water in the ejector, it is possible to reduce the size of the heat source device becomes compact as a dissolving means. And by flowing from upstream of the hot-water heating means water ejector, carbon dioxide in the exhaust gas for more soluble than in water, it is capable of increasing the carbon dioxide concentration in the bath.
