CONSTITUTION:When a blower fan 13, a circulation pump 9, and a suction pump 16 are operated, hot water in a bathtub 5 is sucked from a suction port 7 through a heat exchanger 17, and again jetted and circulated to the bathtub 5 from a nozzle 6. At this time, the suction pump 16 sucks the oxygen enriched air separated by an oxygen separating film 14 and mixes it into the hot water through an air pipe 10. Thus, the hot water jetted from the nozzle forms a bubble flow. The air of the bubble flow is the oxygen enriched air, and a bathing person thus can inhale the oxygen enriched air and comfortably take a bath.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bubble bath with an oxygen enrichment device.

BACKGROUND OF THE INVENTION As shown in FIG. 3, a conventional bubble bath of this type includes a bathtub 1, an inlet 2 for circulating hot water, a pump 3, and a spout for mixing a circulating vortex and air and ejecting the mixture together. 4, and this bubble flow stimulates the body and promotes blood circulation.

Problems to be Solved by the Invention However, with the above-mentioned bubble bath, it is difficult to obtain a comfortable bath because the bathroom is a nearly sealed space and the presence of water vapor components in the bubbles can make it difficult to breathe. Met. In other words, when taking a bath, both blood pressure and pulse rate increase for the human body, but since the air in the bathroom is highly humid, the partial pressure of water vapor increases, and the partial pressure of oxygen relative to the total pressure is lower than that of normal air, which causes an increase in body temperature. The accompanying expansion and contraction of blood vessels limits the amount of oxygen supplied to cerebral cells, causing hot flashes and dizziness.

The present invention has been made in consideration of these points, and aims to enable a comfortable bathing experience with less hot flashes and dizziness.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a bathtub, a circulation pump for circulating hot water in the bathtub, an oxygen enrichment device, and oxygen enriched air generated by the oxygen enrichment device. and a spout for mixing and supplying hot water sent by a circulation pump into the bathtub.

Function: With the above-described structure, the present invention enables comfortable bathing. In other words, oxygen enrichment, so-called high concentration oxygen, is generally
In addition to the effects mentioned above, it is known to have various effects on the human body both physically and mentally.

For example, from a physical perspective, in respiratory disorders such as primary respiratory failure that occur when inhaling car exhaust gas or cigarette smoke, carbon monoxide, which is strongly bound to hemoglobin in the blood, can be easily released. In addition to preventing oxygen deficiency, it is also effective in helping people who do not exercise much on a daily basis recover from so-called anaerobic exercise, which involves continuous intense exercise, preventing heart disease and improving blood vessel health. It is also said to be effective in preventing systemic diseases.

In addition, from a mental perspective, the supply of fresh oxygen to cerebral cells brings about a mental refreshment effect, relieves stress, recovers from lack of sleep, and is also effective in preventing hangovers caused by undigested alcohol. It is said that As mentioned above, the effects of high-concentration oxygen on the human body are various, but by mixing the oxygen-enriched air into bubbles and sending oxygen-enriched air, the aforementioned effects on the human body can be obtained and a comfortable bathing can be achieved.

In addition, the bathroom has excellent airtightness, and the oxygen generated from the oxygen enrichment device can be stably maintained in the bathroom, allowing the oxygen enrichment to fully exert its effects on the human body.

Example An example of this will be described below with reference to FIG. 1 and Part 2.

In Fig. 1, 5 is a bathtub, and the inner wall has a spout 6.
And a suction lower is provided. The spout 6 and the suction lower are connected to a circulation pump 9 via a vibrator 8, and the spout 6 is connected to an air vibrator 10. Reference numeral 11 denotes an oxygen enrichment device, in which raw air that has passed through a filter 12 is taken into the device by a blower fan 13, is caused to flow in the direction of the arrow, and oxygen is separated by an oxygen separation membrane 14, and then exhausted from an exhaust port 15. It has become. 16 is a suction pump that sucks the oxygen-enriched air separated by the oxygen separation membrane 14, and is connected to the air vibrator 10. Note that the suction pump 16 and the circulation pump 9 are installed in the ventilation path of the raw air.

Further, a heat exchanger 17 is provided in the vibrator 8 between the suction lower and the circulation pump 9, and the raw air is heated by hot water flowing through the heat exchanger 17.

In the above configuration, when the blower fan 13, circulation pump 9, and suction pump 16 are operated, the heat exchanger 17 is
The hot water in the bathtub 5 is sucked through the bathtub 5, and the hot water is ejected back into the bathtub 5 from the spout 6 and circulated. At this time, the suction pump 16 sucks the oxygen-enriched air separated by the oxygen separation membrane 14 and mixes it into the hot water via the air vibrator 10. Therefore, the hot water spouted from the spout 6 becomes a bubble flow. Here, the air in the bubble flow is oxygen-enriched air, and the bather can enjoy a comfortable bath by inhaling this oxygen-enriched air.

In Figure 2, the volume of the oxygen separation membrane 14 is 400 x 600.
x400111ffl hollow fiber membrane, bath water temperature set at 45°C, suction pump 16, circulation pump 9, and blower fan 13 operating, oxygen-enriched air production amount, oxygen concentration, raw materials Shows the measurement results of air temperature and outside air temperature.

As is clear from this Figure 2, the maximum oxygen enrichment is ¥50.
L/sin, oxygen-enriched air with an oxygen concentration of as much as 30% can be obtained. Generally, in order for a bubble bath to have the effect of stimulating the human body as bubbles, a flow rate of 20L/min or more is required for the blowout hole. It is possible, and by diluting the oxygen concentration, it becomes possible to install a smaller number of ejection ports.

By the way, there are roughly two types of methods for oxygen enrichment equipment. Air is taken into the equipment, gases other than oxygen such as nitrogen are adsorbed by an adsorbent under pressure, and a pressure reducing valve is used to disturb the nitrogen. υ [PressurSwing A
dosorp) method, and the membrane separation method, which passes air taken in from outside air through an oxygen separation membrane and uses the gas diffusion speed to generate high concentration oxygen, as in this example, but the latter method is more efficient than the former. It is relatively inexpensive, easy to downsize, and can continuously supply oxygen at a stable concentration, which is preferable for generating oxygen-enriched bubbles.

As mentioned above, this oxygen enrichment device 11 includes an oxygen separation membrane 14
Connect the suction pump 16 to the oxygen-enriched air outlet of the
By creating a reduced pressure state, a pressure difference with the atmospheric side is created, and the raw material air on the atmospheric side dissolves on the membrane surface and diffuses within the membrane.
Desorbs from the membrane surface on the vacuum side. The moving speed of oxygen is about 3.5 times that of nitrogen, and as a result, oxygen-enriched air can be produced.

However, the oxygen separation membrane 14 has a problem in that the diffusion speed changes depending on the temperature change of the raw material air, and the supply amount of oxygen-enriched air is not stable. That is, the higher the temperature of the raw material gas in the oxygen separation membrane 14, the higher the solubility of the membrane surface and the faster the membrane movement speed.

However, in the oxygen enrichment device 11 of this embodiment, a suction pump 16 and a circulation pump 9 are provided in the feed air path, and the feed air is preheated by the power U1 heat emitted from these, and a heat exchanger 17 is further provided. Since the air is heated, oxygen-enriched air can be stably generated regardless of changes in the outside air.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) In addition to the pine surge effect that bubble baths have on the human body,
By inhaling oxygen-enriched air, you can relieve stress, recover from fatigue, and relieve sleep deprivation by activating cerebral cells.

(2) When taking a bath, the oxygen supply to cerebral cells is insufficient due to the expansion and contraction of blood vessels as body temperature rises, and the partial pressure of oxygen in the room decreases due to an increase in the partial pressure of water vapor, making you feel breathless and uncomfortable. The highly concentrated oxygen produced by enriched air bubbles makes it easier to breathe and provides a more comfortable bathing experience.

(3) If the raw air is heated by pump exhaust heat and a heat exchanger using the bathtub as a heat source, the performance of the oxygen separation membrane can be improved and the membrane can be made smaller and lighter.

(4) By configuring the raw air to be heated by pump exhaust heat and a heat exchanger using bathtub water as a heat source,
A stable amount of oxygen enrichment can be obtained without being affected by changes in outside temperature.
