【産業上の利用分野】[Industrial applications]

本考案は、浴槽に湯を供給する浴槽用給湯路と、水を供給する浴槽用給水路と が設けられ、前記浴槽用給水路の途中に、水と給湯用バーナの排気とを接触させ る気水接触室が設けられている風呂給湯装置に関する。 The present invention is provided with a bathtub hot water supply passage for supplying hot water to the bathtub and a bathtub water supply passage for supplying water, and the water and the exhaust gas of the hot water supply burner are brought into contact with each other in the middle of the bathtub water supply passage. The present invention relates to a bath water heater provided with a steam contact chamber.

【従来の技術】[Prior art]

上記のような風呂給湯装置では、バーナの排気中の炭酸ガスを溶解させた水を 、浴槽に供給することにより炭酸風呂としている。尚、炭酸ガスの溶解度は、排 気と水との接触面積が大なるほど大となる。そこで、一般的には水を霧状にして から排気と接触させることにより、接触面積が大になるようにしている。又、水 と排気とを接触させることにより、炭酸ガスの溶解度を高めると共に、排熱を効 率的に回収できるようにしている。 図2に風呂給湯装置の従来の全体構成を示す。 浴槽用給水路W2も浴槽用給湯路W4も浴槽2からの逆流を防止する必要があ る。気水接触室1は大気開放されている。そこで、従来、浴槽用給湯路W4も気 水接触室1に接続することにより浴槽2からの逆流を防止していた。つまり、気 水接触室1で浴槽用給湯路W4からの湯と浴槽用給水路W2からの水を混合貯留 して、その貯留水面と浴槽水面との落差を利用して浴槽2に給湯していた。 In the bath water heater as described above, the carbonated bath is formed by supplying water in which carbon dioxide gas in the exhaust gas of the burner is dissolved to the bathtub. The solubility of carbon dioxide increases as the contact area between exhaust gas and water increases. Therefore, generally, the contact area is increased by atomizing the water and then contacting it with the exhaust gas. In addition, by contacting water with exhaust gas, the solubility of carbon dioxide gas is increased and the exhaust heat can be efficiently recovered. FIG. 2 shows a conventional whole structure of a bath water heater. It is necessary to prevent the backflow from the bathtub 2 in both the bathtub water supply passage W2 and the bathtub hot water supply passage W4. The steam contact chamber 1 is open to the atmosphere. Therefore, conventionally, the hot water supply passage W4 for the bathtub is also connected to the steam contact chamber 1 to prevent the backflow from the bathtub 2. That is, hot water from the hot water supply passage W4 for the bathtub and water from the water supply passage W2 for the bathtub are mixed and stored in the steam contact chamber 1, and the hot water is supplied to the bathtub 2 by utilizing the difference between the stored water surface and the water surface of the bathtub. It was

【考案が解決しようとする課題】[Problems to be solved by the device]

気水接触室から浴槽までの給湯経路は、流路抵抗が比較的大きいことが多い。 そのため、単位時間当たりの流量は比較的小さくなる。 従って、上記従来技術のように給湯路からの湯と給水路からの水の両方を気水 接触室を介して給湯すると、気水接触室に貯留される水量が大となり、気水接触 室の容積を大にする必要があった。 本考案の目的は、上記従来欠点を解消して、気水接触室の容積を縮小する点に ある。 The hot water supply path from the steam contact chamber to the bath often has a relatively large flow path resistance. Therefore, the flow rate per unit time becomes relatively small. Therefore, when both the hot water from the hot water supply channel and the water from the water supply channel are supplied through the steam contact chamber as in the above-mentioned conventional technique, the amount of water stored in the steam contact chamber becomes large and the steam contact chamber It was necessary to increase the volume. An object of the present invention is to eliminate the above-mentioned conventional drawbacks and reduce the volume of the steam contact chamber.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

この目的を達成するため、本考案による風呂給湯装置の特徴構成は、前記浴槽 用給湯路と前記浴槽用給水路とが、各別に前記浴槽に接続される、又は、前記浴 槽に連通接続された入水路に各別に接続されていることである。 To achieve this object, the bath water heater according to the present invention is characterized in that the hot water supply passage for the bathtub and the water supply passage for the bathtub are separately connected to the bathtub or connected to the bathtub. That is, they are separately connected to the inlet channels.

【0005】[0005]

【作用】[Action]

給水路からの水だけが気水接触室を介して浴槽又は入水路に接続される。一方 、給湯路からの湯は、給水路からの水と別の経路を介して浴槽又は入水路に接続 される。従って、気水接触室に貯留される水量は従来技術に較べて小になる。 Only the water from the water supply channel is connected to the bathtub or the water inlet channel via the steam contact chamber. On the other hand, the hot water from the hot water supply passage is connected to the bathtub or the water intake passage via a route different from the water from the water supply passage. Therefore, the amount of water stored in the steam contact chamber becomes smaller than that in the conventional technique.

【0006】[0006]

【考案の効果】[Effect of device]

気水接触室に貯留される水量を小にできるので、気水接触室の容積を縮小する ことができる。 Since the amount of water stored in the steam contact chamber can be reduced, the volume of the steam contact chamber can be reduced.
