- the ultraviolet radiation is the advanced technology application in the sterilization of the surfaces of the electronic equipment and devices contaminated or suspected to be contaminated and/or all other equipment and devices.
- the ultraviolet radiation is an effective microbial control process which is often used to sterilize the indoor air, surfaces, water and surgical instruments.
- three types of UV rays namely UV-A (315-400 nm), UV-B (280-315 nm) and UV-C (100-280 nm), are used for the disinfection and sterilization.
- UV-C is preferred to prevent the microbial contamination since it has the most lethal wavelength for the microorganisms.
- the special filters which prevent direct contact with the person and UV light-damping ray traps have been developed.
- UV radiation In the photolytic inactivation process in which UV radiation is used, UV light directly penetrates the microbial cell and kills it by destroying the cell and protein structure.

Description
STERILIZATION CABINET FOR ELECTRONIC EQUIPMENT
Technical Field
The present invention relates to a photolytic and photocatalytic advanced technology sterilization cabinet which provides a safe and effective in-situ sanitation for the surfaces, electronic equipment, devices, and equipment which are contaminated or suspected to be contaminated.
Prior Art
Many applications aimed at the disinfection and sterilization of the indoor areas in order to prevent the airborne and respiratory infections have come to the fore after the COVID- 19 pandemic. It is known that a large number of viruses are easily transmitted between people through a direct and indirect contact. The air exhaled by the infected person and the discharge such as coughing or sneezing can cause the virus to enter the air and transfer it directly to another person and the virus can also be transmitted indirectly after the contact with the table tops, equipment, devices, or surfaces such as door handles which are in common contact with the infected person, and after the contact with the personal belongings of the infected person. Although there are many sanitation practices applied to prevent the spread of the contamination through the indirect contact, their effectiveness against the resistant microorganisms is limited. After the COVID-19 pandemic, the safe and quick in-situ sterilization of the contaminated indoor areas, surfaces, equipment, and devices through the automation has gained even more importance.
In addition to the personal hygiene, the workplace hygiene which has become more important along with the COVID-19 pandemic has been the priority for the medical facilities, universities, schools, offices, technical services, and all other public institutions in the transition to the new normal order. It has become necessary to develop the advanced technology practices for the safe and effective sanitation of the technological equipment such as computers, printers, scanners and all other equipment and devices while sanitizing the indoor areas and surfaces in these areas. In this case, there is a need for an advanced technology sterilization cabinet which provides a safe
and effective in-situ sanitation for the surfaces, electronic equipment, and devices, which are contaminated or suspected to be contaminated and/or all other equipment and devices.
Various disinfection and sterilization strategies are used to prevent the direct and indirect spread of such infections. The prominent disinfection and sterilization practices are mostly physical and chemical inactivation practices which aim to prevent the contamination which may occur during the indirect contact with the indoor areas and surfaces. The main practice to reduce the spread of the microorganisms is to clean the surfaces often with a disinfectant containing ethanol. There are systems which provide the surface sanitation by using a disinfectant in the disinfection of the surfaces of the electronic equipment and devices contaminated or suspected to be contaminated and/or all other equipment and devices. There are the practices based on a disinfecting process and sterilization systems developed to eliminate, or reduce to the acceptable levels, the microbial residues resistant to the conventional disinfectants in the health care facilities, public health facilities and healthcare organizations. None of the inventions patented as the sterilization cabinets in the present system are designed for the electronic equipment and device contaminated or suspected to be contaminated and/or all other equipment and devices. The ultraviolet radiation is the advanced technology application in the sterilization of the surfaces of the electronic equipment and devices contaminated or suspected to be contaminated and/or all other equipment and devices. The ultraviolet radiation is an effective microbial control process which is often used to sterilize the indoor air, surfaces, water and surgical instruments. Depending on the wavelength of the applied UV light, three types of UV rays, namely UV-A (315-400 nm), UV-B (280-315 nm) and UV-C (100-280 nm), are used for the disinfection and sterilization. Among these wavelengths, UV-C is preferred to prevent the microbial contamination since it has the most lethal wavelength for the microorganisms. In order to eliminate the effect of the harmful UV rays on humans when UV-C rays are used to prevent the microbial contamination, the special filters which prevent direct contact with the person and UV light-damping ray traps have been developed.
In the photolytic inactivation process in which UV radiation is used, UV light directly penetrates the microbial cell and kills it by destroying the cell and protein structure. The microorganisms occurring in colony in the photolytic inactivation process sometimes
shade each other and reduce the inactivation efficiency of UV radiation. Thus, the photocatalytic inactivation (T1O2 - UV system) processes have been accepted as a more reliable sterilization process. There is no invention which is based on the use of direct ultraviolet radiation technology and designed for the electronic equipment and device contaminated or suspected to be contaminated and/or all other equipment and devices. The personnel are at risk, who will disinfect the surfaces with a particularly high microbial load in the area, surface and equipment sanitation process using a disinfectant developed for different purposes. Apart from the microbial risk, there is also a chemical risk arising from the disinfectant applied. Since the effects of UV-C radiation on human health are known, such sanitation processes must be carried out in UV-C- proof sealed cabinets without harm to human health in the sanitation of areas, surfaces, equipment and devices using ultraviolet (UV) radiation. It is required that UV radiation is combined with the photocatalytic inactivation (T1O2 - UV system) processes for a more effective and reliable use. A cabinet which is not designed for the electronic equipment and device contaminated or suspected to be contaminated and/or all other equipment and devices should be self-cleaning and provide an effective inactivation for a wide variety of microorganisms and an easy and safe use without threatening human health.
A sterilization method and device are described in the invention in the U.S. patent application document, numbered US2019374890 (A1 ) and with the priority date 29.01.2014, in the state of the art. The invention in said document comprises a sterilization container for holding the surgical instruments in a sterilizer, a plurality of walls defining an interior volume sized to accommodate at least one tool tray, and a filter blocking at least one of the walls defining a ventilation passage area and the ventilation passage area. The surgical instruments used in surgeries are sterilized in the sterilization device in said document. The sterilization device comprises a door defining an interior volume sized to receive a closing wall and at least one tool tray, a door defining at least one of the surrounding walls and a ventilation passage area, and a filter blocking the ventilation passage area. A method for drying the contents in the sterilization container is provided; said method comprises a door defining an interior volume sized to receive at least one tool tray and contents in a sterilization container with a closed wall, such as a plurality of walls. The sterilization device described in the invention in the state of the art provides the sterilization only by drying the instruments used during the surgery by the filter in the cabinet. However, unlike the cabinet in said document, in the cabinet of
the invention subject to the application, the sterilization of all contaminated or not contaminated devices and instruments is carried out by photocatalytic inactivation. The photocatalytic sterilization cabinet in the invention subject to the application has a two- step inactivation mechanism (1 . The photolytic inactivation and 2. The photocatalytic inactivation) and provides the ultraviolet light to be used safely. The photocatalytic sterilization cabinet of the invention subject to the application provides the in-situ and quick sterilization of the electronic equipment, devices contaminated or suspected to be contaminated and/or all other equipment.
A medical cleaning and disinfection vessel is described in the invention in the Chinese patent document, numbered CN109303926 (A) and with the priority date 24.10.2018, in the state of the art. The invention in said document relates to the technical field of the medical cleaning and disinfection vessels and describes a medical cleaning and disinfection vessel. In the disinfection vessel of said document, the top of an inner surface of the container body is attached to one side of the outer surface of a partition plate. The upper part of the outer surface of the partition plate is attached to the lower part of an outer surface of a fixed mounting slot. The inner surface of the fixed mounting slot is attached to an outer surface of a drive motor, and the lower part of the outer surface of a support rod is attached to one side of the outer surface of a small eccentric disk, namely to the lower part of its outer surface. The small eccentric disk is attached to the upper end of a rotating column, the lower part of the outer surface of the rotating column is attached to the output shaft of a motor, and the receiver is attached to the lower part of the outer surface of the container body. The medical cleaning and disinfection vessel can be adjusted, when in use, to be convenient for the user, using the rotating column and an external threaded block and the height can be adjusted according to personal need using the small cubes and a bridging roller. The cleaning and disinfection vessel is better in the disinfection effect and has the adjustment function. In the invention in the state of the art, there is a disinfection vessel in a wheeled cabinet. However, in the invention in said document in question, unlike the invention subject to the application, there is no information on the sterilization with UV light and photocatalytic inactivation method. The photocatalytic sterilization cabinet of the invention subject to the application provides an increase in the efficiency of UV radiation during the disinfection by combining it with the photocatalytic inactivation (T1O2-UV system) processes and can be moved to the desired place thanks to the wheel system thereunder.

In the invention subject to the application, it is provided that it works as long as the timer and the lid are closed, and that the changeover time of the UV lamp is monitored.
In the invention subject to the application, the disinfection is performed by the oxidation and degradation of the organic substances in the active oxygen structure and the removal of the bacteria by the super-oxidation and purification of the air from the undesirable odors and harmful gases. The inactivation is provided on the surface which has been given a photocatalytic antimicrobial quality by coating the surfaces in which the equipment and device to be sterilized are placed and the UV-C beam contact path with the nanometer-sized T1O2 in the anatase phase. It is provided that the cabinet joints of the lid are covered with the air-tight antibacterial silicone cabinet lid gasket with an interlocking channel structure so that the air inside the cabinet does not escape to the outside. The anatase phase is formed, which is a phase of the nanometer-sized T1O2 on the UV light contact surfaces. In order to provide the disinfection by directing the microorganisms to the nanometer-sized TiC coated photocatalytic surfaces, there are two air circulation fans on the lower right and upper right surfaces of the disinfection cabinet to ensure the turbulence of the air entering the cabinet.
