Description

Sterilizer and method for personal portable terminal using ozone {Method and Apparatus for sterilizing of personal portable terminal using ozone}

The present invention relates to the sterilization of personal mobile terminals using ozone, in particular, among the personal portable terminals (mobile phones, PDAs, etc.), the parasitic bacteria which are used in modern mobile phones most frequently used by modern people can be sterilized using ozone (O3). The present invention relates to a personal terminal sterilizer using ozone and a method thereof.

In general, due to the expansion of the personal portable terminal (particularly, mobile phone) market, the use time of modern mobile phones is increasing. The mobile phone is contaminated by the saliva of the caller, which is emitted when the caller speaks or exhales, and germs transferred by the hand when the button is touched, and the cell is maintained at a constant temperature by the heat generated in the phone itself. This is a good condition for bacteria to grow.

In addition, the cell phone is stored in various places such as pockets and bags at the convenience of the user rather than being stored in a specific case, so it is easy to come into contact with many kinds of germs inhabiting each storage place, and is always exposed to the air to float in the air. Since bacteria are easily introduced, various bacteria thrive in the contaminated terminal as described above, thereby causing pathogenic bacterial infections and odors. There is also concern about the spread of viruses through mobile phones. Therefore, there is a need to periodically disinfect and sterilize the mobile phone.

According to Korean Patent Laid-Open Publication No. 2003-0033475 (hereinafter abbreviated as "prior art"), one or more ultraviolet rays which emit ultraviolet rays having sterilizing power inside a seating part of a mobile phone charger part in which a transmission part of a mobile phone is located An apparatus for sterilizing a mobile phone, having a lamp, has been disclosed.

Ultraviolet rays are included in various light sources, including sunlight. Ultraviolet radiation, which has a shorter wavelength than visible blue or violet light, is mainly classified into three types: ultraviolet-A (UVA), ultraviolet-B (UVB), and ultraviolet-C (UVC). Ultraviolet-A with a wavelength of about 320 to 400 nm is not absorbed by the ozone layer. Ultraviolet-B with a wavelength of about 280 to 320 nm is mostly absorbed by the ozone layer, but some reaches the ground surface. Ultraviolet-C, with a wavelength of about 100 to 280 nm, is completely absorbed by the ozone layer.

Ultraviolet rays are bactericidal and can produce vitamin D when irradiated into the body, but UV-A and especially UV-B penetrate the surface of the skin, causing burns and increasing the incidence of skin cancer and cataracts. Can cause.

However, since the disclosed prior art sterilizes the mobile phone using ultraviolet rays which may adversely affect the human body, there is a disadvantage that the risk is always included.

As shown in the figure, it is determined whether the sterilization key is in the ON state when the power is supplied to the sterilization apparatus. First steps (S101 to S104) determining whether the door is opened or closed by searching the output of the detection sensor; When the door is open as a result of the determination of the first step, a warning alarm is generated, and when the door is closed, the ozone generator is driven to generate ozone into the sterilization chamber. S108); A third step (S109 to S111) for checking an elapsed time when ozone is generated and displaying a progress state, and illuminating a sterilization display LED in the sterilization chamber to identify that sterilization is performed from the outside; The checked ozone generation elapsed time of the third step is compared with a preset setting time for turning off the operation of the ozone generator. When the checked ozone generation elapsed time is equal to or larger than the set time, In operation S112 to S114, the driving is turned off and the sterilization display LED is turned off.

The method for sterilizing a personal terminal using ozone according to the present invention made as described above will be described in more detail.

First, when power is supplied to the sterilization apparatus 100 in step S101, it is determined in step S102 whether the sterilization key 121 is on (on), if the sterilization key 121 is not on (on) In step S103, the controller waits for a key input. On the contrary, when the sterilization key 121 is in the on state, the controller 110 moves to step S104 to search for the output of the door open / close detection sensor 140.

In step S105 it is checked whether the door is closed as a result of searching for the door opening or closing, and if the door is open as a result of the check, the process moves to step S106 to generate a warning alarm. When the warning alarm occurs, the user can easily recognize that the door of the sterilization chamber is open, and then close the door for sterilization.

On the other hand, if the door is closed as a result of searching for the door opening and closing, the process moves to step S107 to drive the ozone generator 160 to generate ozone into the sterilization chamber 110. In operation S108, the ozone generated by driving the fan is forcedly transferred when the ozone generated is injected into the sterilization chamber 110 so that the ozone is evenly contacted to the personal portable terminal.

Next, in step S109, the internal timer is started to check the elapsed time of ozone generation, and in step S110, the sterilization progress state is displayed.

Here, the sterilization progress status display may display the sterilization progress status by displaying warning messages such as total sterilization time, remaining sterilization time, ozone generation, sterilization, and disinfection of door opening.

In addition, when ozone generation starts, the sterilization display LED 112 in the sterilization chamber 110 is turned on as in step S111 to easily identify that sterilization is performed from the outside.

Next, in step S112, the checked ozone generation elapsed time is compared with a preset set time (for example, 5 minutes) in order to turn off the operation of the ozone generator 160, and the checked ozone generation elapsed time is determined. If less than the set time, the flow returns to step S107 to drive the ozone generator and the following steps.

On the contrary, if the checked ozone generation elapsed time is equal to or greater than the set time, it is determined that sterilization is finished, and the flow proceeds to step S113 to turn off the operation of the ozone generator 160 and to move to step S114. The sterilization display LED 112 is turned off.

Then, when the sterilization display LED 112 in the sterilization chamber is turned off, the user may determine that sterilization is finished, and the user may withdraw his portable terminal from the sterilization chamber.

According to the present invention as described above, there is an effect that can safely and completely disinfect and sterilize the portable terminal of the individual susceptible to various bacteria.
