Description

Plasma Clothes-Hanger

The present invention relates to a'functional hanger', which releases plasma on the hanger to remove various bacteria and pathogens (Microbes, Virus) from clothes, and removes and deodorizes VOC (Volatile Organic Compounds). It is a hanger'.

A hanger is a hanger for displaying, storing and drying clothes without creases.

The hanger shape consists of a frame for hanging clothes and a hook for hanging clothes. Coat hangers for tops come in various shapes such as hooks and triangular frames or folding. The hanger for the bottom is equipped with a hook and clip on the frame. Various materials such as metal wire, wood, and plastic are used for the hanger material.

Hangers developed up to now are very vulnerable to sterilization, antibacterial or deodorizing functions, and to solve this point, a hanger was introduced for the purpose of removing and deodorizing various bacteria of clothing, or incorporating technologies using fragrances. For sterilization, antibacterial and deodorization, a functional hanger was also devised to install an LED-lamp, UV-lamp, and anion generating ionizer on the frame of the hanger. These LED-lamps or UV-lamps are sterilized by a little ozone by ionizing oxygen in the air around the lamp mainly by ultraviolet rays of short wavelength UV (Ultra-Violet). Anion generating ionizer mainly uses the function of killing microorganisms of fungi by the action of anions.

The conventional patents related to functional hangers are as follows.

(1)'Hanger with sterilization function (Registration Patent Publication No. 10-0763053)' proposes a hanger with a sterilization function using an ultraviolet lamp (UV-LED lamp).

(2)'Sterilization hanger (Public Utility Model Publication No. 20-2011-0006814)' discloses a sterilization hanger using an ultraviolet lamp.

(3) The'multifunctional coat hanger (Registration Patent Publication No. 10-1670225)' is a coat hanger with a deodorizing function mainly by attaching an ultraviolet LED-lamp to the shoulder hanger.

(4) The'Clothing Manager (Registration Patent Publication No. 10-1312024)' proposed a method of dissolving an antibacterial agent and a deodorant in water and spraying air bubbles by heating in an aqueous solution state.

(5)'Hanger with sterilization and deodorization function (Public Patent Publication No. 10-2016-0129452)' is a hanger using ozone and OH by UV using a UV lamp.

(6)'Smart variable hanger (Public Patent Publication No. 10-2017-0050799)' is a hanger capable of directional and antibacterial by attaching a spray of air freshener and antibacterial agent to the hanger.

(7) ‘Functional hanger (Patent Publication No. 10-2017-0102128) proposed a hanger with a fragrance and sterilization function by installing a fragrance, a lamp, and an ionizer generating negative ions on the hanger frame. The lamp is described as "a light source selected from ultraviolet rays, plasma, LEDs, and combinations thereof". However, it is understood to mean a UV-lamp generating plasma from the lamp, but the concept of lamp-plasma is unclear.

In addition, (8)'Ozone Sterilizer (Public Utility Model Publication No. 20-2011-0008136)' proposes a closet with sterilization function by attaching an ozone generator to a'clothing cover' where a hanger can be placed. There is no mention of it. In addition, there is a clothing management device in the form of hanging inside the closet with the product name of'Plasma Cleaning'. This is a kind of sterilizer using plasma.

The prior art is a functional hanger of deodorization and sterilization using an ultraviolet lamp (discharge tube UV-lamp or UV-LED lamp) or a corona discharge type negative ion generator using a needle-shaped electrode.

In the method of using ultraviolet rays or negative ions of corona discharge, the density of excitation particles such as ozone or OH that acts as a sterilization is small, so the effect of sterilization and deodorization is very insignificant, and the effectiveness is low.

The present invention is a plasma hanger of sterilization and deodorization using a plasma source of a dielectric barrier discharge method. As a dielectric barrier discharge of atmospheric discharge, it uses the effect of sterilization and decomposition of organic matters of oxygen-based positive and negative ions and oxygen-based excitation species (ROS) according to plasma generation. In addition, particles such as cation and anion of hydrogen series (H and OH), and radicals are generated in high concentration. In particular, in the atmospheric plasma of the dielectric barrier discharge method, various kinds of radicals including positive and negative ions are generated at a high concentration, thereby performing sterilization, deodorization and decomposition of organic matter.

The plasma source of the present invention uses a dielectric barrier discharge (DBD), which is a method of the “plasma emission diode device (application number 10-2017-0132897)”, which is the patent application of the present inventor.

Conventional functional hangers having deodorizing and sterilizing effects use a UV-LED-lamp, a discharge tube-type UV-lamp, an ionizer using a needle electrode, or a plasma cluster. These are all deodorization and sterilization by ozone (O ₃ ) and OH-species. However, the amount of O ₃ and OH generated in these lamps and bed discharge devices is weak, and there is a limit to the deodorization and sterilization effects.

In particular, since the discharge tube type UV-lamp has a large size and high power consumption, there is a time limitation in using a secondary battery for a short time with a single charge.

The present invention is to propose a plasma hanger having a function of sterilization by emission and diffusion of plasma, decomposition of organic matter, and deodorization by installing a plasma generating device (plasma source and power supply) on the frame in a hanger composed of a hook and a frame.

The dielectric barrier discharge (DBD) method for plasma generation of the present invention is characterized by a so-called'surface-dielectric barrier discharge (S-DBD)' by forming electrodes respectively on the upper and lower surfaces of the dielectric layer. The S-DBD generates high-concentration plasma (plasma density 10 ¹⁷ -10 ¹⁸ m ^-3 ) and high-concentration ozone (occurrence concentration 10 ¹⁹ -10 ²¹ m ^-3 ) on the surface of the dielectric layer. In order to apply the S-DBD method to a hanger, it is necessary to control the amount of plasma and ozone generated. In addition, in order to realize a practical portable hanger using a wireless'type' method using a secondary battery for charge and discharge, it is necessary to minimize power consumption and ensure long-term use for several days with a single charge of a predetermined secondary battery.

In the present invention, the solution for the plasma hanger is (1) a method of installing on a hanger frame through miniaturization of the plasma device and power supply device, and (2) the amount of plasma gas and ozone generated from the plasma device is arbitrarily adjusted, Technology to maximize sterilization and deodorization effects, (3) Technology to control the amount of ozone generated from plasma to less than 0.05 ppm of ozone concentration, which is a safety standard that is not harmful to the human body, (4) Secondary battery for charging and discharging for user convenience The purpose is to make it portable by using (5) to increase the usage time by charging a secondary battery once, and (6) to provide a practical plasma hanger for electrical safety and user convenience.

The means for solving the problems of the present invention are as follows.

(1) Easily installed on hanger frames due to miniaturization of plasma devices and power devices. The configuration of the device is composed of a plasma source, a DC-AC inverter with a transformer, a secondary battery for charging and discharging, and a DC-DC converter, and a PCB-board with a power circuit that controls the amount of plasma generated.

(2) The amount of plasma gas and ozone generated from the plasma device can be arbitrarily adjusted. In the plasma source, the amount of ozone generated is controlled to be less than the safety allowable value by adopting a dimming method (power ON/OFF time control) mainly for power supplied from the secondary battery.

(4) Secure electrical safety and user convenience. Plasma hangers that use rechargeable secondary batteries must be able to be used for a considerable period of at least a week on a single charge. Since the plasma hanger's deodorization and sterilization effect is very good, it has a sufficient effect by hanging clothes on the hanger and plasma operation for about 10 minutes. Therefore, when a predetermined time elapses after hanging clothes on a hanger and turning on the switch, the power is automatically cut off and the time to be turned off is arbitrarily adjusted.

Plasma hanger according to the present invention removes various pathogens adsorbed on clothes, prevents various pests (somes), and provides comfortable clothes by safe storage of clothes due to deodorization by decomposing organic matter. You can safely store clothes in your home closet, office closet, clothing store or laundry.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is an embodiment of a plasma hanger equipped with a plasma generating device.

FIG. 1(a) is a diagram of a power supply part appearing on an exterior of a hanger frame, and FIG. 1(b) is a view showing a plasma generating device part installed inside the hanger frame.

In Figure 1 (a), the hanger 100 is composed of a hook 10 and a frame 20 that maintains and stores the shape of clothes, and an ON/OFF switch 21 and a power supply installed on the exterior of the frame 20 It consists of a display LED (22) indicating operation, and a charging socket (23). When the switch 21 is pressed, the display-LED 22 emits light to indicate that the plasma device is operating. According to the present invention, after a predetermined time after the switch 21 is pressed, the display-LED 22 automatically flashes to stop the operation of the plasma device. The switch 21 may use a switch equipped with an LED-element, and in this case, it is not necessary to arrange a separate display-LED 22. The charging socket 23 is a USB terminal or a terminal such as a 5-pin used for charging a smartphone to be useful in real life, and it is preferable to connect a charger 70 and a charging connector 71 corresponding thereto.

1(b) is a diagram of a power supply device installed inside the hanger frame 20, and includes a control module 30, a DC-DC converter-1 (31), a converter-2 (32), and a transformer (33). It consists of an inverter 34, a plasma source 35, a secondary battery 40, and a charging board 50 including. These boards can also be manufactured and mounted in a single module form. In addition, a small-fan 60 may be installed for diffusion of plasma.

2 is a block diagram showing the configuration of a plasma generating device by operation of a power supply installed inside a frame of a plasma hanger.

The charge/discharge secondary battery 40 mainly uses Li-ion Battary, for example, a product having an electric capacity in the range of 500-1000 mAh, and the output voltage is usually DC 3.7 V. Since the plasma hanger of the present invention uses a current of approximately 1 mA, the arithmetic use time of the secondary battery reaches 500-1000 hours with a single charge.

The output DC-voltage of the secondary battery 40 is inputted to the control module 30 through the converter-2 32 through the operation of the ON/OFF switch 21, and the display-LED 22 The operation status is displayed. The switch 21 may use a switch in which an LED is built into the switch itself, and in this case, the display-LED 22 may be omitted. On the other hand, the output DC-voltage of the secondary battery is input to the DC-AC inverter 34 through the converter-1 (31), and the output terminal of the transformer 23 to which the AC voltage is output is input to the plasma source 35 And plasma is generated.

The control of the amount of plasma generated by the plasma source 35 has a dimming method in the control circuit 32 and a function of automatically shutting off power after a predetermined time. In the dimming method, plasma is generated at the ON-time by adjusting the DC-voltage on/off at a constant duty ratio for a predetermined period of time, and the plasma generation is stopped by shutting off the power at the OFF-time, thereby reducing the amount of plasma generated and ozone generation. Control. After the power switch 21 is turned on on the hanger, the power is automatically cut off after a predetermined time (for example, 10 minutes), and plasma generation is controlled in a manner that does not generate more than necessary for a long time, and a secondary battery ( 40) to increase the period of use. The secondary battery 40 is charged by inserting the charging connector 71 of the mobile phone charger 70 into the charging socket 23 installed on the charging board 50. When using the electric capacity of the secondary battery (DC 3.7 V output) of 500 mAh, the power consumption of the power supply device of the present invention is about 1 W, and the current of the secondary battery is about 250 mA, so the usage time is about 2 hours. When the power is automatically cut off after 10 minutes by the action of the switch 21 once, the operation of the switch 21 of the plasma hanger is possible about 12 times, so it is an arithmetic calculation that the switch 21 can be used for 12 days by operating the switch once a day. .
