からなつている。 Conventionally, this type of bath has three components: a blow-off pipe that supplies bath water to the bathtub, an air supply pipe that is connected to the blow-off pipe and supplies external air to the blow-off pipe, and a blow-out pipe that applies pressure to the bath water and blows it out from the blow-off pipe. It consists of a pressure feeding means such as a pump that generates a flow, and a pressurizing means such as a pump that pressurizes the air.

問題点がある。<Problems to be solved by the invention> Therefore, in conventional baths, air intake is performed at the flow rate of the bath water passing through the blow-off pipe, and if the flow rate is low, a large amount of air cannot be inhaled. , it is extremely troublesome to adjust the flow velocity. For this reason, if the capacity of the bath water pressure feeding means and the air pressurizing means is increased, the spouting speed of the bath water will increase and the pine surge effect will increase, but at the same time the overall size of the device will increase, making it difficult to use in the home. It becomes unsuitable for use and becomes expensive.
There is a problem.

At the same time, a small-diameter jet nozzle is attached to the end of the flow path on the jet side to increase the jet speed, and ozone is spewed out from the tube below the jet nozzle to rise, and the ozone is added to the bath water spouting above. It is characterized by mixing.

道水、井戸水等の節約が図られる。 FIG. 1 is a piping system diagram of a bathtub to which the present invention is applied. A blowout pipe 2 and a suction pipe 3 are installed above and below one side of a bathtub 1, and a circulation pipe is connected between these pipes. A circulation path 4 is formed. In this circulation path 4, a filter 5, a heating means 7 such as a bath kettle, and a pressure feeding means 8 such as a pump are arranged in series in this order. The filtration device 5 removes scale, human hair, etc. from the bath water in the bathtub 1, and is provided with a filtration cloth such as polyurethane or glass wool, and a deodorizing agent such as activated carbon. The heating means 7
Then, the bath water is heated to a set temperature, and then the bath water is sent to the blow-off pipe 2 at a predetermined pressure by the pressure-feeding means 8, and is squirted into the bathtub 1 from the outlet of the blow-off pipe 2.
Moreover, an air supply pipe 9 is connected to this blow-off pipe 2,
This air supply pipe 9 is provided with a pressurizing means 6 such as a pump and a purifier 10 to supply clean air from which dust has been removed. Reference numeral 9a denotes a trap portion formed in the air supply pipe 9, which is curved to be higher than the water level of the bath water in the bathtub 1 and prevents the bath water from flowing back into the air supply pipe 9. be. Note that a check valve may be connected to the air supply pipe 9 instead of this trap section. 11
is an ozone generator, whose pipe 12 is connected to the blow-off pipe 2, and the ozone from the ozone generator 11 is spouted into the bath water to sterilize the bath water and provide medical care and cleaning to bathers. It's becoming like that.
Therefore, with the above configuration, bath water is filtered,
Since it is sterilized and heated, it can be used repeatedly, saving tap water, well water, etc.

槽内に供給することができる。 In such a bath system, the blow-off pipe has a structure as shown in FIG. This blow-off pipe 2 consists of a main body 21 and an outlet pipe 22 that is screwed into the open end of the main body 21. A packing 23 is provided between the main body 21 and the outlet pipe 22, and the blow-off pipe 2 is connected to the bathtub through the packing 23. It is attached to 1. The bath water flows into the blow-off pipe 2 from the left end in the figure, and is ejected from the right end.In the main body 21, from the upstream side, there are a first flow path 24, a second flow path 25, and a second flow path. Three channels 26 are arranged in series in the longitudinal direction. Here, the cross-sectional area between the respective flow paths is the largest in the third flow path 26, the second in the first flow path 24, and the smallest in the intermediate second flow path 25. The air supply pipe 9 is connected to the downstream third flow path 26 having the largest cross-sectional area via the joint 13, and air is mixed into the bath water within the third flow path 26. be exposed. Note that the first flow path 24 is formed with a tapered surface 24a whose diameter gradually decreases toward the second flow path 25. With such a configuration, the bath water flowing into the main body 21 is compressed in the second flow path 25 and then rapidly expanded in the third flow path 26, so that the bath water flows into the main body 21. Inside 26, the pressure is reduced,
The air from the air supply pipe 9 flows vigorously into the third flow path 2.
6 and mixed with water. Therefore, a large amount of air can be sucked in well, and a large amount of air bubbles can be supplied into the bathtub.

させる効率上、好ましい。 Next, a jet nozzle 27 extending in the direction of the third flow path 26 is attached to the outlet pipe 22 . This jet nozzle 27 is supported by a closing plate 28 that closes the open end surface of the outlet pipe 22, and has a diameter that is approximately the same as or slightly larger than that of the second flow path 25. The diameter of the flow path 26 is smaller than that of the flow path 26 of FIG. This jet nozzle 27 is connected to the third flow path 2
The bath water mixed with air is spouted into the bathtub 1 in the bathtub 6, but because it is formed with a small diameter, the amount of jetted water is smaller than that of the bath water in the third flow path 26. The bath water pressure in the passage 26 becomes high, so that the bath water is forcefully jetted out from the spout nozzle 27 under pressure. For this reason, the upstream flow paths 24, 25, 2
The bath water whose flow velocity has been increased in step 6 further increases in flow velocity at this jet nozzle 27, so that it is jetted into the bathtub 1 as a jet water stream. As a result, even if the capacity of the pressure-feeding means 8 is small, bath water can be spouted at a high flow rate. Here, the longer the length of the blowout nozzle 27 in the direction of the third flow path 26, the more the above effect increases. In good condition. In FIG. 2, the main body 21 and the outlet pipe 22
A tube 13 installed through the bathtub 13 is a tube that spouts ozone into the bathtub 1, and is connected to a pipe 12 from the ozone generator 11. As a result, ozone is mixed into the bath water and a sterilizing effect is added, making it possible to treat and clean bathers. Note that it is preferable that the tube 13 be located below the jet nozzle in terms of efficiency in mixing ozone into the bath water.

Therefore, air suction is improved and a large amount of air is mixed with the bath water, and a small-diameter jet nozzle is attached to the end of the jet side, so the jet speed of the bath water increases and the water flows while mixing ozone. It can strengthen the force of the bath water and enhance the pine surge effect.
Therefore, the capacity of the bath water pumping means and the air pressurizing means can be reduced, and it can be applied to domestic baths and can be provided at low cost.

As the ozone concentration increases, ozone performs sterilizing, deodorizing, and decolorizing effects through contact oxidation with the bath water, and decomposes impurities such as oil, calcium, and ammonia on the surface of the bath water. By simultaneously injecting ozone and air to the human body, it gives a pine surge effect to the human body, and further cleanses and deodorizes the human body. In addition, ozone that rises in the bath water and is released as a gas into the bathroom prevents mold and bacteria in the bathroom and deodorizes it.
