Description

Technology Field

[0001] The present invention relates to an oxygen supply device for supplying oxygen into the interior of a building, and more specifically, to an oxygen supply device incorporating a flame-retardant oxygen supply line that effectively facilitates the installation of the oxygen supply line by preventing damage to the oxygen supply line in the event of a fire and configuring the oxygen supply line to have flexibility while improving manufacturability of the oxygen supply line. Background Technology

[0002] Generally, the effects of oxygen deficiency on the human body have been well known through various papers and news reports.

[0003] For example, a lack of oxygen can cause serious impairment in brain function, leading to headaches, memory loss, senility, and cerebral softening, as well as a decline in liver function and slowed blood circulation.

[0004] In particular, when a person drinks alcohol, the alcohol breaks down into acetaldehyde, which is then further broken down into carbon dioxide and water; this process requires three molecules of oxygen. Therefore, the more alcohol a person drinks, the more oxygen is required, and the greater the oxygen deficiency becomes.

[0005] In addition, general drinkers often engage in excessive smoking along with drinking. Smoking increases the body's need for oxygen while hindering the smooth supply of oxygen through the lungs, so the combination of drinking and smoking causes an excessive oxygen deficiency in the body. Therefore, it is necessary to supply a larger amount of oxygen to drinkers, especially those who also smoke.

[0006] Recently, methods using oxygen generators to produce and supply oxygen indoors have also been employed. An oxygen generator is a mechanical device that separates air drawn in from the outside into oxygen and non-oxygen gases, and various types have been developed. Methods for generating oxygen from such generators include the Pressure Swing Adsorption method using adsorbents and the Gas Separation Membrane method utilizing differences in gas diffusion and permeation rates.

[0007] Furthermore, an oxygen supply device is a system for supplying oxygen generated from an oxygen generator to a desired location, and such an oxygen supply device includes an oxygen generator, an oxygen supply line for accurately and safely supplying the oxygen generated from the generator to the desired location, and a controller.

[0008] Such an oxygen supply device can be applied to residential homes and office spaces in buildings, and aims to provide a comfortable environment by maintaining the oxygen concentration in the location at an optimal level.

[0009] Meanwhile, the oxygen supply line used in the oxygen supply device can be composed of an oxygen pipe through which oxygen travels and an LED wire through which electricity travels. Conventionally, when manufacturing an oxygen supply line, a conduit is prepared first, the oxygen pipe is inserted into the conduit, and then the LED power wire is inserted and installed. Consequently, there were problems with the manufacturing process being complex, not easy to produce, and requiring a long production time.

[0010] In addition, as a conduit with a large inner diameter was used to install oxygen pipes and LED wires, the overall volume of the oxygen supply line increased, and when such oxygen supply lines were installed inside the duct cable, they took up a lot of space, which resulted in a problem of reduced utilization efficiency of the duct cable.

[0011] In addition, when the oxygen supply line was exposed to fire during a fire, there was a problem in that the LED wires and oxygen pipes inside the conduit were easily damaged by the fire.

[0012] Furthermore, when such oxygen supply lines are laid in the installation space, in the case of curved sections or sections bent at a certain angle rather than straight sections, the oxygen supply lines cannot bend properly in response to the curves or sections bent at a certain angle, making the laying work difficult and resulting in an unsightly appearance. In particular, there was a problem where the oxygen supply lines were easily damaged when they were bent excessively during the installation process in curved sections or sections bent at a certain angle.

[0021] More preferably, the oxygen generator may further include any one of an air purification unit for removing foreign substances and odors from the air introduced from the outside, a sterilization unit for sterilizing the concentrated oxygen, and a dehumidification unit for removing moisture from the concentrated oxygen.

Specific details for implementing the invention

[0034] The configuration and operation according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0035] This is intended to provide a detailed explanation sufficient for a person skilled in the art to easily implement the contents of the present invention, and does not imply that the technical concept and scope of the present invention are limited thereby.

[0036] In addition, when assigning reference numerals to the components of each drawing, it should be noted that they are indicated by the same numeral. Furthermore, terms specifically defined in consideration of the configuration and operation of the present invention may vary according to the intent or convention of the user or operator, and the definition of such terms should be determined based on the content throughout this specification.

[0037] First, the configuration of an oxygen supply device to which a flame-retardant oxygen supply line according to one embodiment of the present invention is applied can be broadly divided into an oxygen generator that generates oxygen, an oxygen supply line that moves the generated oxygen and power, an oxygen discharger that discharges the moved oxygen into a room, and a controller that controls the oxygen discharge from the oxygen discharger. Each configuration will be examined in more detail below with reference to the illustrated drawings.

[0038] First, the oxygen generator (100) is,

[0039] In cases where it is used in relatively small spaces such as houses, a Pressure Swing Adsorption (PSA) method may be used. For example, it may be configured to include an oxygen concentrator equipped with an adsorption tower made of a zeolite adsorbent and an air compressor that supplies compressed air to the oxygen concentrator. Concentrated oxygen can be generated by adsorbing a relatively dominant amount of nitrogen within the adsorption tower due to the difference in adsorption capacity from the compressed air supplied into the oxygen concentrator.

[0040] And the concentrated oxygen is supplied to where it is needed via the oxygen storage tank (110), and the nitrogen adsorbed in the adsorption tower can be separated from the adsorption tower when the air pressure applied to the adsorption tower is released and becomes atmospheric pressure.

[0041] In such an oxygen generator (100), air is compressed to a pressure between 2.5 and 3.5 atmospheres and supplied to an oxygen concentrator, and nitrogen adsorbed in the oxygen concentrator is desorbed and discharged under atmospheric pressure.

[0042] In addition, when used in relatively large spaces such as office buildings, oxygen can be separated from atmospheric nitrogen using the Vacuum Swing Adsorption (VSA) method.

[0043] This allows oxygen to be concentrated as a relatively large amount of nitrogen is adsorbed onto the adsorption tower while passing through an oxygen concentrator under atmospheric pressure, and the nitrogen adsorbed onto the adsorption tower can then be desorbed and separated by maintaining a vacuum inside the oxygen concentrator.

[0044] Meanwhile, the oxygen generator (100) may include an air purification unit to remove foreign substances and odors from the air drawn into the interior as needed. For example, a HEPA filter, a fine dust removal filter, or both may be installed in the intake unit that introduces air into the interior of the oxygen generator (100), and the concentrated oxygen may be configured to pass through a separate ultrafine dust removal filter before being released into the room.

[0045] Additionally, the oxygen generator (100) may further include a dehumidification unit to remove moisture generated during the oxygen concentration process as needed, and may also further include a sterilization unit to irradiate the oxygen being moved into the room with ultraviolet rays of a wavelength of 250 to 280 nm so that the oxygen is moved into the room in a sterilized state.

[0046] Here, the air purification unit, dehumidification unit, or sterilization unit described above may be provided in the oxygen discharge unit (300) described later, rather than inside the oxygen generator (100).

[0047] In addition, a magnetization generator may be installed in the oxygen storage tank (110) where oxygen concentrated from the oxygen generator (100) is temporarily stored to convert the stored oxygen into highly reactive oxygen and move it into the room.

[0048] Here, the magnetization generating unit can be configured such that, for example, a permanent magnet with an N pole is installed on the upper surface of the oxygen storage tank (110) and a permanent magnet with an S pole is installed on the lower surface of the oxygen storage tank (110), thereby causing the oxygen stored in the oxygen storage tank (110) to be placed within the magnetic field range of the permanent magnets so that the oxygen is magnetized. The magnetized oxygen can act as an ion compared to ordinary oxygen and can also be expected to have a deodorizing effect, thereby allowing fresher oxygen to be supplied indoors.

[0049] And the oxygen supply line (200) is,

[0050] The oxygen supply line (200) connects the oxygen generator (100) and the oxygen discharger (300) to each other and may be composed of an oxygen pipe (210) for moving oxygen generated from the oxygen generator (100) to the oxygen discharger (300), and an LED wire (220) for connecting the power supply unit (120) of the oxygen generator (100) and the oxygen discharger (300) to supply power for lighting, etc. of the oxygen discharger (300).

[0051] And the oxygen supply line (200) can be installed through the interior of the ceiling or wall so that external exposure is minimized, and in environments where it is difficult to install through the interior of the ceiling or wall, it can be processed using molding, etc., or it can be installed through electrical, communication lines or air conditioning lines installed in the building.

[0052] The oxygen supply line (200) may be configured such that a fire-resistant fabric (211) is wrapped around the outer circumference of an oxygen pipe (210) made of polyurethane material in a braided or woven manner to prevent damage in case of fire, and the outer circumference of an LED wire (220) may also be configured such that a fire-resistant fabric (221) is wrapped around it in a braided or woven manner.

[0053] Here, the fireproof fabric (211)(221) may be composed of a fireproof composite yarn, and the fireproof composite yarn may be manufactured using, for example, a fiber formed from a cellulose silicate fiber and one or more nitrogen-containing polymers selected from polyacrylonitrile, polyimide, meta-aramid, or para-aramid.

[0054] That is, it can be manufactured into a refractory composite yarn by including a blending process in which fibers formed from cellulose silicate fibers and nitrogen-containing polymers are mixed, a carding process and a carding process in which fibers are aligned, a drawing process in which fibers are drawn to produce a finer sliver, a roving process in which twists are applied, a spinning process in which cohesive force is applied to maintain strength, a quick-drying process in which process moisture content is maintained, a winding process in which yarns are wound, a plying and twisting process, and a rewinding process in which yarns are wound again. Such a refractory composite yarn can increase durability, mechanical strength, impact resistance, heat resistance, flame retardancy, and flame resistance.

[0055] The refractory composite yarn may further include carbon fibers as needed. Carbon fibers are fibers produced by carbonizing natural compounds containing carbon, such as cellulose, and synthetic materials such as acrylic fibers, vinylon, and pitch. Depending on the processing temperature, changes in molecular arrangement and crystal structure occur. They have high heat resistance and impact resistance, are lighter than metals, and possess superior elasticity and strength compared to metals. Carbon fibers are also called flame-retardant fibers and may include oxypolyacrylonitrile fibers, which are inert carbon fibers.

[0056] The fireproof fabric (211)(221) may also be constructed by weaving or braiding ceramic fibers as another example, and the heat resistance may be further improved by coating the ceramic fibers with silicone rubber.

[0057] Here, it is preferable to use ceramic fibers made of one or more types selected from the group consisting of silica, alumina, and zirconia.

[0058] And as another embodiment, if a mica tape satisfying the fire resistance standard IEC 60331-11,21 (750°C, 90 minutes) is wrapped around the outer circumference of the oxygen pipe (210) or LED wire (220) instead of the fire-resistant fabric (211) (221), the oxygen pipe (210) or LED wire (220) can be protected for a certain period of time or longer even at high temperatures of 700 to 800°C.

[0059] Here, mica tape can be manufactured by adhering mica powder to glass fiber or PE (polyethylene) tape.

[0060] Meanwhile, the oxygen pipe (210) and LED wire (220), which are formed by wrapping with fireproof fabric (211)(221), can subsequently be formed by wrapping with a fireproof coating (250) in an extrusion molding method using equipment such as a coated wire extruder.

[0061] In addition, the fireproof coating (250), which is installed by wrapping the oxygen pipe (210), LED wire (220), and filler (230) in an extrusion molding manner using equipment such as a coated wire extruder, forms the outer shape of the oxygen supply line (200) and performs the function of mechanically protecting it. The material of the fireproof coating (250) may be an insulating material such as rubber, resin, polyethylene, PVC, or olefin-based polymer material, and may be modified in various ways within the scope of known technical concepts depending on the purpose of use and installation environment.

[0062] Meanwhile, the oxygen pipe (210), LED wire (220), and filler (230) wrapped in fireproof fabric (211) (221) may be configured to be directly wrapped with a fireproof coating (250), and in another embodiment, the oxygen pipe (210), LED wire (220), and filler (230) wrapped in fireproof fabric (211) (221) may be configured to be wrapped with a nonwoven fabric, and the fireproof coating (250) may be wrapped around the outer circumference of the nonwoven fabric.

[0063] Here, the nonwoven fabric may be selected from cellulose materials, synthetic organic polymer-based materials, glass fibers, and mixtures thereof, preferably selected from synthetic organic polymer-based materials, and may be composed by adding illite, an eco-friendly inorganic material, to the nonwoven fabric to improve flame retardancy and prevent environmental pollution.

[0064] In addition, as another embodiment, the nonwoven fabric may be composed of a nonwoven fabric with excellent flame retardancy by manufacturing it from polyacrylonitrile-based, cellulose-based, or phenol-based calcined carbon fibers.

[0065] In another embodiment, as shown in (a) of FIGS. 2 to 3, an oxygen pipe (210) and an LED wire (220) wrapped in a fireproof fabric (211) (221) may be fitted into a flexible metal corrugated pipe (240), and then a fireproof coating (250) may be extruded and wrapped around the outer circumference of the flexible metal corrugated pipe (240).

[0066] Here, when only the oxygen pipe (210) and LED wire (220) wrapped in the internal fire-resistant fabric (211)(221) of the flexible metal corrugated pipe (240) are accommodated, the oxygen pipe (210) and LED wire (220) wrapped in the fire-resistant fabric (211)(221) may move inside the flexible metal corrugated pipe (240), and there is no particular problem even if they move. However, if you want to prevent movement, you can also configure it by putting a filler material (230) together with the oxygen pipe (210) and LED wire (220) wrapped in the fire-resistant fabric (211)(221) inside the flexible metal corrugated pipe (240) as shown in FIG. 3 (b).

[0067] Here, the filler (230) may be composed of components of general rubber, synthetic rubber, polyfluoroalkoxy, TFE / Perfluoromethyl-vinylether, ethylene chlorotrifluoroethylene, polyvinyl chloride (PVC), smokeless flame-retardant PVC, fluorinated ethylene propylene (FEP), fluorinated perfluoroethylene polypropylene, fluoropolymer type, flame-retardant polypropylene, and other thermoplastic materials, but a heat-resistant nylon-based filler (230) may also be used.

[0068] The nylon-based filler (230) can be formed by assembling multiple nylon yarns produced through a process including: a first process of mixing resin with stone powder having a particle size of about 1000 to 5000 mesh to produce a stone powder lump having a size of about 2 to 5 mm; a second process of mixing about 10 to 90 weight percent of the stone powder lump produced through the first process and about 10 to 90 weight percent of polyamide in a mixing device; a third process of mixing the stone powder lump and polyamide through the mixing device and then feeding it into a high-temperature film extruder to extrude a film having a certain surface area and thickness; and a fourth process of supplying the extruded film to a stretching machine to lower the linear density and thereby produce a nylon yarn.

[0069] In this way, when the oxygen pipe (210) and LED wire (220) wrapped in fireproof fabric (211) (221) are wrapped in a flexible metal corrugated pipe (240) and then a fireproof coating (250) is wrapped around the outside of the flexible metal corrugated pipe (240) to form an oxygen supply line (200), the oxygen pipe (210) and LED wire (220) can be safely protected by the flexible metal corrugated pipe (240).

[0070] In addition, when the oxygen supply line (200) is laid in a curved section or an angled section, it can be bent appropriately in response to the curved section and the angled section, and the bent state can be maintained appropriately, so the laying of the oxygen supply line (200) can be done accurately, quickly, effectively, and simply, and the appearance of the oxygen supply line (200) can be made aesthetically pleasing, and when the oxygen supply line (200) is bent in response to the curved section and the angled section, it can be prevented from being excessively bent by the flexible metal corrugated pipe (240), thereby resolving the problem of the internal oxygen pipe (210) and LED wire (220) being unnecessarily bent and damaged.

[0071] Additionally, when the oxygen pipe (210) and LED wire (220) wrapped in fireproof fabric (211) (221) are wrapped in a flexible metal corrugated pipe (240) and then a fireproof coating (250) is wrapped around the outside of the flexible metal corrugated pipe (240) to form an oxygen supply line (200), the fireproof coating (250) may be wrapped around the outer circumference of the nonwoven fabric while the nonwoven fabric is wrapped around the flexible metal corrugated pipe (240).

[0072] Meanwhile, when an oxygen pipe (210) and an LED wire (220) formed by being wrapped with fire-resistant fabric (211) (221) are installed in a flexible metal corrugated pipe (240) and a fire-resistant coating (250) is wrapped around the outer circumference thereof, as shown in FIG. 4 (a), a coating cutting member (260), such as a thin thread of fibrous material, a thin string of resin material, or a thin steel wire of metal material, is installed together along the longitudinal direction of the flexible metal corrugated pipe (240), and the ends of the coating cutting member (260) are formed to protrude a certain length from the ends of the flexible metal corrugated pipe (240), and the flexible metal corrugated pipe (240) and the coating cutting member (260) are wrapped together with the fire-resistant coating (250), then when removing the fire-resistant coating (250), the coating cutting member (260) can be removed without using a tool. By pulling, the fireproof coating (250) can be easily cut and removed, so the workability of removing the fireproof coating (250) can be improved.

[0073] Here, when a covering member (260) is included, when an oxygen pipe (210) and an LED wire (220) wrapped in a fire-resistant fabric (211) (221) are installed in a flexible metal corrugated pipe (240), a filler (230) may also be installed together inside the flexible metal corrugated pipe (240).

[0074] Additionally, when a coating cutting member (260) is included, the fireproof coating (250) may be wrapped around the outside of the flexible metal corrugated tube (240) with a nonwoven fabric wrapped around it, and when the flexible metal corrugated tube (240) is wrapped with a nonwoven fabric, it is preferable that the coating cutting member (260) be installed between the nonwoven fabric and the fireproof coating (250).

[0075] Meanwhile, the LED wire (220) wrapped in fireproof fabric (221) and the oxygen pipe (210) wrapped in fireproof fabric (211) may be configured by being selectively received and installed in a flexible metal corrugated pipe (240) together with a filler (230) in a parallel state, and then wrapped in a fireproof coating (250). However, the LED wire (220) wrapped in fireproof fabric (221) may be configured by being selectively received and installed in a flexible metal corrugated pipe (240) together with a filler (230) in a state where it forms a spiral shape along the longitudinal direction of the oxygen pipe (210) wrapped in fireproof fabric (211) and completely wraps the outer circumference, and then wrapped in a fireproof coating (250), thereby the oxygen pipe (210) wrapped in fireproof fabric (211) is externally It can also be protected from heat more effectively.

[0076] And, as shown in Fig. 4 (b), a tension line (270) may be installed along the longitudinal direction at the center or eccentrically inside the oxygen supply line (200) configured in this way. Although this prevents excessive bending of the oxygen supply line (200) to some extent by the flexible metal corrugated pipe (240), if it bends excessively in a severe state, the oxygen supply line (200) may be damaged along with the flexible metal corrugated pipe (240).

[0077] Therefore, it is desirable to configure it so that even if the oxygen supply line (200) is severely bent excessively, it can generate tensile strength to prevent damage to the oxygen supply line (200) in advance.

[0078] Here, the tension wire forms the central framework of the oxygen supply line (200) and may be composed of materials that are rigid and have some elasticity, such as Kevlar aramid yarn, fiber glassepoxy rod, FRP (Fiber Reinforced Polyethylene), high-strength fiber, steel wire, steel wire, etc., to generate tensile strength. Additionally, the material of the tension wire (270) may be composed of a shape memory alloy so that it can freely change its shape according to the laying path during the laying process of the oxygen supply line and then return to its original state when necessary.

[0079] In addition, the oxygen supply line (200) may be configured such that, in one embodiment, the aforementioned nonwoven fabric is provided to improve fire resistance performance, a heat-resistant paint is applied to the inner surface of the nonwoven fabric, a heat-resistant paint is applied to the outer surface of the nonwoven fabric, or a heat-resistant paint is applied to both the inner and outer surfaces of the nonwoven fabric.

[0080] In addition, as another embodiment for improving the fire resistance performance of the oxygen supply line (200), a heat-resistant paint may be applied to the inner surface of the fire-resistant coating (250), a heat-resistant paint may be applied to the outer surface of the fire-resistant coating (250), or a heat-resistant paint may be applied to both the inner and outer surfaces of the fire-resistant coating (250).

[0081] In addition, as another embodiment for improving the fire resistance performance of the oxygen supply line (200), a heat-resistant paint may be applied to the inner or outer surface or the inner and outer surfaces of the flexible metal corrugated pipe (240), or the heat-resistant paint may be applied to the inner or outer surface or the inner and outer surfaces of the flexible metal corrugated pipe (240) and the heat-resistant paint may be applied together to the inner or outer surface or the inner and outer surfaces of the fire-resistant coating (250).

[0082] Here, the heat-resistant paint may be a high-heat-resistant paint having a constant viscosity, and it is desirable that it solidifies within a short time after application. It may also be a silicone paint with added polyurethane or an organic silicone paint with added aluminum powder so that the coating state can be maintained stably at high temperatures.

[0083] The oxygen discharger (300) is,

[0084] It is a device that is connected to an oxygen supply line (200) and installed indoors, and discharges oxygen into the room through the oxygen pipe (210) of the oxygen supply line (200).

[0085] The oxygen discharger may include a lighting means, and the lighting means is connected to the power supply unit (120) of the oxygen generator (100) through the LED wire (220) of the oxygen supply line (200), so that the lighting means operates in accordance with the operation of the oxygen discharger (300), and the operating status of the oxygen discharger (300) can be visually checked.

[0086] In addition, if the oxygen discharger (300) also functions as a humidifier, a drive motor for driving the vibrator may be configured to be connected to the power supply unit (120) of the oxygen generator (100) through an LED wire (220).

[0087] These oxygen dischargers (300) do not need to be fixed in any one form and may be configured as a ceiling-type discharger installed on the ceiling, a wall-type bubble discharger installed on the wall, a stand-type discharger that can be placed on a desired location and moved nearby, or a wall-type communication outlet discharger using a wall-type communication outlet installed on the wall.

[0088] The controller (400) is,

[0089] It is a device installed on one side of the room to control the operation and driving of the oxygen generator (100).
