  However, in the conventional configuration, an oxygen supply unit is provided in the middle of the pipe line of the jet pipe, and oxygen-enriched air is supplied to the supply unit. It was necessary to have this system, and it was not easy to install at home. Moreover, since the flow rate of the jet bath is large, it has been difficult to use for a long time in relation to electricity bills and noises, and it has been difficult to supply sufficient oxygen.

  The present invention solves the above-mentioned conventional problem, and is enriched in the recirculation circuit of the water heater having a recirculation circuit that circulates hot water in a bathtub by a pump, which is installed in most households. It can be installed at low cost by mixing a gas such as high-concentration oxygen from the device and ejecting it from the bathtub bubble ejection device using the bath adapter attached to the bathtub, and the circulation flow rate is small, so it can be used for a long time. An object is to provide an apparatus capable of supplying a gas such as oxygen.

  Further, by attaching a detachable check valve, it is possible to prevent the backflow to the pump or the like and improve the safety.

  In order to solve the above-described conventional problems, a bathtub bubble ejection device according to the present invention includes a recirculation circuit that circulates hot water in a bathtub using a pump, a mixing unit that mixes gas into the recirculation circuit, and the mixing unit. A nozzle that ejects the gas mixed in the recirculation circuit via the nozzle, and is provided with a detachable check valve upstream of the mixing means, and the check valve can be connected to a gas pipe It is set as the structure which has.

  This makes it possible to easily obtain a gas with a higher concentration, such as oxygen, by simply modifying a part of the pursuit device that is always used, and adding an oxygen enrichment device, etc. By attaching a check valve, it is possible to prevent the backflow to the pump or the like and improve safety.

  The bathtub bubble ejection device of the present invention mixes a gas such as high-concentration oxygen from an oxygen enricher or the like into a recirculation circuit that circulates bathtub water installed in most households and performs a reheating operation. By using a bath adapter attached to the bathtub, it can be installed at low cost and the circulation flow rate is low, so it is possible to supply gas such as oxygen for a long time and promote the warm bath effect. In addition, it is possible to prevent the patient from taking a nap during bathing, and it is also expected that the cleaning effect is enhanced by the generation of ultrasonic waves when the bubbles burst. Further, by attaching a detachable check valve, it is possible to prevent the backflow to the pump or the like and improve the safety.

  According to a first aspect of the present invention, there is provided a recirculation circuit that circulates hot water in a bathtub by a pump, a mixing unit that mixes gas into the recirculation circuit, and a gas that is mixed into the recirculation circuit via the mixing unit.

Gases such as oxygen with high concentration from the enrichment device are mixed into hot water or water in the reheating pipe, and when the hot water or water mixed with oxygen is ejected from the reheating adapter attached to the bathtub, A gas such as high-concentration oxygen forms bubbles 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. Moreover, even if it is gas other than oxygen and air, the washing | cleaning effect etc. are anticipated by generation | occurrence | production of the ultrasonic wave etc. when a bubble bursts. Further, by attaching a detachable check valve, it is possible to prevent the back flow to the pump or the like and improve safety. If the check valve is removed, it can be used as a normal bath adapter.

  According to a second aspect of the present invention, in the first aspect of the invention, the connecting portion between the mixing means and the check valve can be swung, so that the oxygen and air pipes can be connected from either direction and are narrow. It can be connected even in the construction space.

  According to a third aspect of the present invention, the mixing means has a constricted portion between the outlet of the check valve and the circulation passage, and prevents dirty water and dust from entering the hot water circulation path. .

  According to a fourth aspect of the present invention, a filter is provided in the gas passage of the mixing means, and dirty water and dust can be prevented from entering through the hot water circulation path.

  The fifth aspect of the invention has a structure in which a passage length of 5 times or more the passage diameter is provided between the air inlet of the mixing means and the nozzle, while the air mixed in the hot water passes through the passage. It is made uniform and the sound when the jet is ejected becomes quieter.

  In the sixth aspect of the invention, the case of the check valve is formed of a material having good thermal conductivity such as metal, and even when hot water circulates through the pipe even when the check valve is frozen by condensed water or the like in winter. The heat of the hot water is transmitted to the case, and the check valve can be released from freezing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
