Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for supplying air-treated oxygen-enriched air to a bathroom.

[0002]

2. Description of the Related Art Oxygen is indispensable for producing energy in the living body, but unlike the nutrient source from food, only a very small amount is accumulated in the body,
Oxygen therapy for directly supplying oxygen to the oral cavity is performed for patients with insufficient oxygen such as respiratory failure and abnormal blood gas composition. In addition, even for general people who do not need such oxygen therapy, by actively taking in oxygen from the outside, it is possible to increase oxygen consumption in the body and recover physical strength. It is also known that you can get a refreshing feeling. Except for a specific place such as a well-equipped hospital, this kind of oxygen is transported and brought in by being manufactured in a factory and filled in an oxygen cylinder, and used in various types such as an oxygen condenser, a humidifier, or a flow meter. It is used with all the equipment.

[0003]

However, when treating high-concentration oxygen as in the above-mentioned oxygen therapy, it is necessary to consider the oxygen concentration, its amount, supply method, etc. in order to avoid obstacles. There was trouble such as requiring the instructions and guidance of a doctor. Further, since oxygen has a flammability property, its management is troublesome. Further, the oxygen cylinder is expensive, and its maintenance is expensive when it is used constantly. Therefore, it has been the actual situation that the use of oxygen has hardly been performed in the general public.

In view of the above circumstances, the present invention does not need to directly handle high-concentration oxygen such as the use of an oxygen cylinder, and therefore does not need to be instructed or instructed by a doctor and requires no special equipment. The purpose is to make such oxygen easily available to the general public and to improve health.

[0005]

In order to achieve the above-mentioned object, the present invention provides a nitrogen-reduced air by an oxygen generator equipped with an oxygen-enriching material for treating the air to reduce the nitrogen. An oxygen supply mechanism for a bathroom, characterized by supplying oxygen-enriched air to the bathroom by using the oxygen-enriched air directly from the oxygen generator into the bathroom without passing through a duct. An oxygen supply mechanism, a bathroom oxygen supply mechanism for adding a fragrance to the oxygen-enriched air and supplying the oxygen into the bathroom, and further, the oxygen-enriching material is a nitrogen adsorption catalyst for bathroom oxygen. A supply mechanism, or alternatively, an oxygen supply mechanism for the bathroom in which the oxygen-enriching material is a nitrogen separation membrane, and further, a valve for switching the flow path between the bathroom side and the atmosphere side is provided on the outlet side of the oxygen generator. Provide the above-mentioned oxygen-enriched sky Of the bathroom, the oxygen supply mechanism for the bathroom that activates the nitrogen adsorption catalyst by the suction and decompression process by the air supply unit, and the fan inside the oxygen generator, the air flow by the fan An oxygen supply mechanism for the bathroom, which is combined with the oxygen-enriched air to supply it into the bathroom, or two sets of the nitrogen adsorption catalysts are used, and by switching the flow paths, nitrogen is adsorbed by forward flow of air and reverse flow of air is performed. This is to propose an oxygen supply mechanism for bathrooms that alternately desorbs nitrogen.

[0006]

The oxygen generator is provided inside and outside the bathroom with an oxygen-enriching material that adsorbs nitrogen or separates nitrogen and an air supply means, and by driving the air supply means in a bath state where bathing is possible, The air is sucked, the sucked air permeates the oxygen-enriching material, the nitrogen is reduced, and the air relatively enriched in oxygen is blown into the bathroom. The bathroom has sufficient humidity, and the blown oxygen-enriched air can create an oxygen-enriched atmosphere in the bathroom with water added, so that bathers can use oxygen-rich air without fear of injury. By inhaling the modified air, it is possible to improve the health such as recovery of physical strength and refreshing feeling. By supplying oxygen-enriched air to the bathroom directly from the oxygen generator, the loss of wind energy can be suppressed.

By adding a fragrance to the oxygen-enriched air supplied to the bathroom, it is possible to further enhance the refreshing feeling and provide mental stabilization such as stress relief. Although many commercially available solid and liquid flavors can be used, phytoncide extracted from forest trees is preferred. This phytoncide is said to activate the cerebral cortex, stabilize autonomic nerves, help eliminate stress and insomnia, and purify and activate indoor air.
It brings a unique refreshing feeling. Phytoncide is in liquid form and can be carried in the oxygen-enriched air stream by gas-liquid contact means such as dripping or spraying in a perfume supply device.

A nitrogen separation membrane module and a nitrogen adsorption pellet packed bed can be preferably used as the oxygen enriching material for reducing nitrogen. The nitrogen separation membrane module uses a polymer separation membrane having a difference in the solubility of oxygen and nitrogen and the degree of diffusion within the membrane, and is one that depressurizes the outlet side by air feeding means to allow air to permeate.
The nitrogen adsorption pellet packed bed has a large specific surface area and has a molecular sieving action and is excellent in nitrogen adsorption, and the catalyst made of zeolite is pelletized and packed into a container, and the air pressurized by the air supply means or the air reduced in pressure is permeated. In any case, the oxygen concentration in the air can be increased within the range of 25 to 35%.

In the oxygen supply mechanism that interrupts the supply of oxygen-enriched air to activate the nitrogen adsorption pellets, the supply of oxygen-enriched air to the bathroom is interrupted by switching the flow path on the outlet side of the oxygen generator. Then, by closing the air intake of the oxygen generator and continuing the operation of the air supply means, the nitrogen adsorbed pellet packed bed is decompressed, the adsorbed nitrogen is desorbed and activated, and nitrogen-enriched air is released to the atmosphere. Can be made.

By operating the fan in the oxygen generator, the air flows even when the supply of the oxygen-enriched air due to the activation treatment of the nitrogen adsorption pellets is interrupted, and the bather does not feel uncomfortable due to the interruption of the oxygen-enriched air. , You can continue to feel refreshed.

In the oxygen supply mechanism having two sets of packed beds of nitrogen adsorbing pellets, oxygen-enriched air is supplied to the bathroom by nitrogen adsorption in the packed bed of nitrogen adsorbing pellets on one side by switching the air flow path and at the other side. Adsorbed nitrogen is desorbed by the countercurrent air flow in the nitrogen adsorption pellet packed bed, and the air flow path is switched to supply the oxygen-enriched air to the bathroom by the forward flow air in the nitrogen adsorption pellet packed bed on the other side. The activation process is performed by desorbing the adsorbed nitrogen by the backward air in the packed bed of nitrogen adsorbed pellets, and the oxygen-enriched air is continuously supplied into the bathroom.

Further, a small fan 20 is provided inside the box of the oxygen generator 6 in addition to the air pump 17, and its conduit 21 is connected to the conduit 22 from the perfume supplier to enrich the oxygen. It is designed to join the air with the air flow. The solenoid valve 15 and the direction switching solenoid valve 18 are controlled by a program of the controller 10 arranged outside the bathroom 1.

In the oxygen generator 6, when the switch 11 in the bathroom 1 is pushed, the air pump 17 is started, and the solenoid valve 15 and the direction switching solenoid valve 18 are opened to open all the paths. The air sucked from the suction port 7 passes through the dust filter 13 and the mist separator 14, becomes clean dry air, and is supplied to the nitrogen adsorption pellet chamber 16.

At this time, if hot water is supplied to the bathtub 5 of the bathroom 1,
Moisture is added by the steam to form a bathroom 1 having a scented and healthy enriched oxygen-air atmosphere, and the bather keeps blood circulation due to the bathing and exceeds 21% oxygen exceeding the oxygen concentration in the atmosphere. By inhaling air, you can recover physical strength and relieve stress, and feel refreshed. Further, even when the supply of the oxygen-enriched air for the activation treatment of the nitrogen adsorption pellets is interrupted, the air flow is supplied by the fan 20, so that the refreshing sensation is maintained. In addition,
A general bathroom is not completely closed, and an excess air amount due to the supply of oxygen-enriched air is exhausted through a gap between openings such as doors and windows, so it is not necessary to consider exhaust equipment.

In addition, instead of the above mechanism for adsorbing and desorbing nitrogen by changing the degree of pressure reduction in one nitrogen adsorption pellet chamber,
It is also possible to provide two nitrogen adsorption pellet chambers and alternately perform the oxygen enrichment treatment and the activation treatment of the nitrogen adsorption pellets. The configuration diagram of FIG. 3 shows the configuration of the oxygen generator 23 according to the second embodiment. A blower 26 with a motor is arranged in the vicinity of the suction port 24 and with a dust filter 25 interposed therebetween. The 2-port position switching solenoid valve 28 for controlling the direction is connected via the separator 27, and the pipe lines 29A, 29B are branched from the 2-port position switching solenoid valve 28 to connect to the nitrogen adsorption pellet chambers 30A, 30B, respectively.
