Description

Technology Field

[0001] The present invention relates to an oxygen supply device for supplying oxygen to a room, and more specifically, to an oxygen supply device capable of supplying oxygen by diffusing it into a room, wherein oxygen is supplied to a room through an oxygen discharger installed in a room while connected to the oxygen supply device, and configured so that oxygen can be rapidly and evenly diffused and supplied throughout a large room, thereby enabling effective oxygen supply to a large room using a small number of oxygen dischargers. 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 oxygen generated from the oxygen generator to the desired location, an oxygen discharger for discharging oxygen into the room, and a controller for controlling the oxygen supply device.

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

[0009] Meanwhile, conventionally, an oxygen discharger connected to an oxygen supply device and an oxygen supply line is installed on the ceiling of the room, and oxygen traveling along the oxygen supply line is supplied into the room through the oxygen discharger. In the case of typical houses, the indoor area is not large, so the oxygen supplied from the oxygen discharger could be sufficiently delivered to the entire indoor space.

[0010] However, in the case of large spaces such as offices, it is difficult for oxygen to be effectively delivered throughout the entire indoor space, and when combined with a natural ventilation rate of about 30% or the use of ventilation devices such as air conditioners, there was a problem in that it was difficult for oxygen to sufficiently spread throughout the entire indoor space of the office.

[0011] Therefore, in the past, in the case of large spaces such as offices, there was a problem in that the installation cost of the equipment increased and maintenance of the equipment became inconvenient as multiple oxygen generators were used and a large number of oxygen dischargers were installed and used.

Specific details for implementing the invention

[0033] 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.

[0034] 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.

[0035] 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.

[0036] First, an oxygen supply device capable of diffusing and supplying oxygen into a room according to one embodiment of the present invention can be broadly classified into an oxygen generator that generates oxygen, an oxygen supply line composed of oxygen pipes and LED wires, an oxygen discharger that supplies oxygen into a room, and a diffusion device that diffuses the oxygen supplied from the oxygen discharger into the room. Each component is described in more detail below with reference to the exemplified drawings.

[0037] First, the oxygen generator (100) is,

[0038] When 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.

[0039] 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.

[0040] 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.

[0041] In addition, when applied to relatively large spaces such as office buildings, oxygen can be separated from atmospheric nitrogen using the Vacuum Swing Adsorption (VSA) method.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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).

[0046] 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.

[0047] Here, the magnetization generating unit can magnetize oxygen by, for example, installing a permanent magnet with an N pole on the upper surface of the oxygen storage tank (110) and a permanent magnet with an S pole on the lower surface of the oxygen storage tank (110), so that the oxygen stored in the oxygen storage tank (110) is placed within the magnetic field range of the permanent magnets, and the magnetized oxygen can act as an ion compared to ordinary oxygen and can also be expected to have a deodorizing effect, thereby supplying fresher oxygen to the room.

[0048] The oxygen supply line (200) is,

[0049] The oxygen generator (100) described above and the oxygen discharger (300) described below are connected to each other, and the configuration may consist of an oxygen pipe (210) for moving oxygen generated from the oxygen generator (100) to the oxygen discharger (300), and an LED wire (220) that electrically connects the power supply unit (120) of the oxygen generator (100) and the oxygen discharger (300) to supply power necessary for lighting, etc. of the oxygen discharger (300).

[0050] And these oxygen pipes (210) and LED wires (220) can be arranged and laid out by being tied together with a binding means such as a tie, or can be arranged and laid out by being housed in a combined duct cable, etc.

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

[0052] The oxygen discharger (300) is,

[0053] It is a device that is installed indoors while connected to an oxygen supply line (200) and supplies oxygen to the indoors through the oxygen pipe (210) of the oxygen supply line (200).

[0054] The oxygen discharger (300) may include a lighting unit such as an LED lamp, and this lighting unit 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 unit operates according to the operation of the oxygen discharger (300), and the operating status of the oxygen discharger (300) can be visually checked.

[0055] 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).

[0056] These oxygen dischargers (300) do not need to be fixed in any one form and can be classified into ceiling type installed on the ceiling, wall type installed on the wall, stand type that can be placed at a desired location and moved nearby, or outlet type using a communication outlet installed on the wall.

[0057] FIG. 2(a) illustrates a ceiling-type oxygen discharger (300) installed on the ceiling. The specific configuration may consist of a housing (310) having an overall shape such as a square or a circle, with an internal space (313). The upper surface of the housing (310) may be positioned inside the ceiling (700), and the lower surface of the housing (310) may be fixed so as to be exposed to the interior outside the ceiling (700).

[0058] And a fitting valve (311) communicating with an internal space (313) is installed on the upper surface of the housing (310), and at least one outlet (312) is formed on the lower surface of the housing (310), so that oxygen moved along the oxygen pipe (210) can be supplied to the indoor space through the outlet (312) by passing through the fitting valve (311) and the space (313) connected to the oxygen pipe (210).

[0059] The controller (400) is,

[0060] It is a device installed on one side of the room to control the operation and driving of the oxygen generator (100).

[0061] The controller (400) can be connected to the control unit (130) of the oxygen generator (100) via a wired connection through a controller wire (230), and if necessary, a receiving module can be placed in the control unit (130) of the oxygen generator (100) and a transmitting module capable of communicating with such a receiving module can be placed in the controller (400) so that the oxygen generator (100) can be driven and operated wirelessly through the controller (400).

[0062] Meanwhile, in the case of the oxygen pipe (210) connecting the oxygen storage tank (110) of the oxygen generator (100) and the indoor oxygen discharger (300), the LED wire (220) connecting the control unit (130) of the oxygen generator (100) and the indoor oxygen discharger (300), and the controller wire (230) connecting the control unit (130) of the oxygen generator (100) and the controller (400), they may be configured as a single undivided line, but when laying them through the interior of the wall and ceiling to minimize external exposure, a branching point (600) is placed at one place inside the room, preferably inside the ceiling that is opened by cutting a part of the ceiling, and the divided oxygen pipe (210), LED wire (220), and controller wire (230) are laid using this branching point (600), and the divided oxygen pipe (210) and By connecting the LED wire (220) and the controller wire (230) to each other, the installation and maintenance of the oxygen pipe (210), the LED wire (220), and the controller wire (230) can be facilitated through the branch point (600).

[0063] The diffusion device (500) is,

[0064] It serves to spread oxygen supplied into the room through the aforementioned oxygen discharger (300) far and evenly throughout the room, and can be a blower fan or a cooling fan.

[0065] As an example of a specific configuration, it may be composed of a cylindrical guide frame (510) and a wing (520) that rotates inside the guide frame (510) and is connected to a motor (530) located above the center of the guide frame (510), and the motor (530) may be connected to the aforementioned LED wire (220).

[0066] Here, the LED wire (220) connected to the motor (530) may be a wire branched from the LED wire (220) connected to the oxygen discharger (300), and the LED wire (220) may be configured to consist of multiple wires, with one being connected to the oxygen discharger (300) and the other being connected to the motor (530).

[0067] Meanwhile, the diffusion device (500) is installed to be connected to the oxygen discharger (300) so as to diffuse the oxygen supplied from the oxygen discharger (300) in the required direction, and the diffusion device (500) may be installed on the upper surface of the housing (310) of the oxygen discharger (300), installed inside the housing (310) of the oxygen discharger (300), or installed on the lower surface of the housing (310) as needed.

[0068] That is, as shown in Fig. 2(b), when the diffusion device (500) is installed on the upper surface of the housing (310) of the oxygen discharger (300), the upper surface of the housing (310) is open, and the guide frame (510) of the diffusion device (500) is connected to the upper surface of the open upper surface, and a sealing part (540) is formed in a dome shape on the upper surface of the guide frame (510) so that the internal seal can be maintained, and a fitting valve (311) connected to the oxygen pipe (210) can be installed through the upper center of the sealing part (540) in a state where the seal is maintained.

[0069] Accordingly, oxygen moved along the oxygen pipe (210) passes through the fitting valve (311) and moves to the airtight sealing section (540). The oxygen moved to the airtight sealing section (540) is influenced by the blade (520) installed on the guide frame (510) and rotated by the motor (530), and passes through the discharge port (312) provided on the bottom surface of the enclosure (310) so that it can be rapidly and evenly diffused into the room.

[0070] And, as shown in FIG. 3 (a), when a diffusion device (500) is installed inside an oxygen discharger (300), the upper surface of the housing (310) equipped with a fitting valve (311) can be configured to be openable and closable while maintaining airtightness, and a diffusion device (500) including a guide frame (510) and a blade (520) rotated by a motor (530) is installed in the space (313) of the housing (310), and the discharge port (312) on the bottom surface of the housing (310) is formed to be larger than the overall size of the blade (520), so that oxygen moved by the rotation of the blade (520) can move smoothly through the discharge port (312).

[0071] In addition, a protective net may be installed in this discharge port (312) to prevent foreign matter from entering the space (313) of the housing (310) and affecting the rotation of the wing (520) or to prevent a person's hand from touching the wing (520) and getting injured.

[0072] Accordingly, oxygen moved along the oxygen pipe (210) passes through the fitting valve (311) to the space (313) of the enclosure (310), and then, under the influence of the wing (520), passes through the outlet (312) provided on the bottom surface of the enclosure (310) and can be rapidly and evenly diffused into the room.

[0073] In addition, as shown in Fig. 3(b), when the diffusion device (500) is installed on the bottom side of the housing (310) of the oxygen discharger (300), the top of the guide frame (510) of the diffusion device (500) can be installed in a state spaced apart from the bottom side of the housing (310) of the oxygen discharger (300) through a plurality of spacing members (550).

[0074] At this time, it is preferable that the center of the hull (310) and the center of the guide frame (510) be configured to coincide with each other.

[0075] Accordingly, oxygen moved along the oxygen pipe (210) passes through the fitting valve (311) and moves to the space (313) of the enclosure (310), and then is discharged through the discharge port (312) at the bottom of the enclosure (310). The discharged oxygen can be rapidly and evenly diffused downwards by means of a blade () that is rotated by the driving of the motor (530) in the diffusion device (500) located at the bottom of the enclosure (310).

[0076] Meanwhile, the lighting unit connected to the LED wire (220) may be configured to be installed on the bottom surface of the housing (310) of the oxygen discharger (300) as described above, but if the diffusion device (500) is installed inside the housing (310) of the oxygen discharger (300) or on the bottom surface of the housing (310), the lighting unit may be installed on the diffusion device (500) rather than on the bottom surface of the housing (310), and the lighting unit may be activated when the wing (520) of the diffusion device (500) rotates, thereby allowing the oxygen supply status to be checked through the operation of the diffusion device (500).

[0077] As described above, the detailed description of the present invention has explained specific embodiments, but it is understood that various modifications are possible within the scope of the described content. Therefore, the scope of the described content does not need to be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
