Description

Hand dryer providing sterilizing effact}

This is a hand dryer that can simultaneously dry and disinfect hands by washing hands in tap water for hygiene management and chlorine dioxide with excellent agility when drying wet hands by the wind. And technology related to a sterilization device.

In more detail, the hand dryer provided by the present technology includes a drive unit in which a fan driven by a motor generates wind, a pipe through which the air generated from the drive unit is discharged to the air outlet, and a heater and a sustained-release chlorine dioxide supply unit inside the air outlet pipe. And a hand dryer that includes a sensing sensor that detects the user's hand coming in and a control unit that regulates the power of the motor, and the motor fan operates when the hand is detected by the sensing sensor and power is supplied to the driving unit. Therefore, it is a technology related to a hand dryer or sterilization device that can simultaneously dry and sterilize hands by moving along the air outlet along with gaseous chlorine dioxide, which has excellent agility when wind of an appropriate temperature passes along the pipe.

The hand is a body organ that is in direct contact with all surfaces. As it is known that an average adult touches about 30 surfaces in one minute, the hand is always in contact with something, so it is often pointed as a path of transmission of various diseases.

In fact, the survival period varies depending on where the bacteria or virus sticks to, but in general, it can survive from 5 minutes to 2 days or more. In most cases, infection is caused by touching the nose or mouth after contact with a hand or object.

However, if you keep your hands clean, 80% of infectious diseases can be prevented, and the management method is not expensive, time-consuming, or complicated, and whenever the opportunity arises, wash thoroughly with soap for 30 seconds in running water and dry well. If you do, you can keep your hands clean.

When using a hand dryer during the process of washing your hands, there is a study that if you do not dry your hands completely, the bacteria remaining on your hands may increase by more than 500% by the wind from the hand dryer. Just as mold grows easily, wet hands can be a cause of cross-infection because it helps microbes spread.

According to a study on the number of germs according to the hand drying method conducted at the University of Westminster in the UK in 2008, when using a hand towel, the bacteria on the hands decreased by 77% compared to before washing, but 254% for a general air dryer and 42 for a high speed hand dryer. The percentage increase appears to show a very shocking result.

As such, hygiene is the same principle that must be observed, and if hygiene is the most important place, it can be said that the use of a hand dryer actually poses many risks. In general, mold is 20~25℃, bacteria is 30~ Since it is cultivated at 35°C, a hand dryer that blows out a lot of water and a warm breeze can achieve a fantastic compatibility, so recently hand dryer manufacturers are promoting that it is equipped with an antibacterial filter, but its efficacy is insignificant.

Hand dryers are mostly operated by sensing the hand with a sensor and then inhaling the toilet air through a motor and blowing the wind through the vent. Considering that the inhaled air is inside the toilet, the wind from the hand dryer There is a high possibility that bacteria will be detected. Therefore, if the hand dryer is inevitable, you should pay special attention not only to the cleanliness of the bathroom, but also to the interior of the hand dryer and filters. There is a risk of spreading and resulting in exposure to various diseases.

In the KBS "Consumer Complaint" program broadcast on May 28, 2010, information related to the hygiene of hand dryers in toilets such as terminals, restaurants, subways, and university hospitals with large floating populations was aired. In the ventilator, 39 kinds of bacteria, including Staphylococcus aureus, which can cause food poisoning, and 19 kinds of fungi were detected. In addition, there was a case where all kinds of dust, body fluids and debris of insects such as cockroaches and mosquitoes were found and shocked.

The same type of investigation was dealt with year after year through TV media such as MBC's "Zero Complaint" program on August 17, 2011 and MBN "Rediscovery of Life" on September 25, 2012, and each time the results are incredibly terrible. It has been reported, but there are no improved results since then.

The paradoxical result of detecting more bacteria in the hands after use than before using the hand dryer gives us a sense of ridiculousness.At first, we washed our hands for hygiene and cleanliness, but in the process of drying our hands, it became more contaminated. As a result of throwing away, air dryers developed and researched so far have been structurally a result of being a breeding ground for all kinds of pathogenic bacteria and fungi.If you can improve this and dry your hands in a hygienic way, that is a competitive edge. I can.

Na ₂ SiO ₃ + H ₂ SO ₄ ⇒Na ₂ SO ₄ + SiO ₂ (silica gel) + H ₂ O-----<Scheme 2>

If silicate is included as silicon dioxide (SiO ₂ ) in an amount of 15 parts by weight or more. The three-dimensional network network structure can be clearly made by the solid silica sol/gel method by inorganic supply, but rather, the chlorine dioxide present with the network structure releases chlorine dioxide to provide hand drying and hand disinfection at the same time. As there is a problem that this is very difficult, it is desirable to maintain the concentration of the proposed silicate.

On the other hand, as in Examples 1 to 3, after installing a sustained-release chlorine dioxide supply unit capable of gradually releasing a source of chlorine dioxide having excellent agility, inside the piping, the wet hands of Examples 1 to 3 were dried. In this case, it was confirmed that diseases caused by pathogens can be sufficiently prevented according to the technical composition of the present application as the reduction rate of E. coli, Pseudomonas aeruginosa and pneumococcus all showed 99.9% as well as providing a comfortable condition without moisture in the hands.

In 2020, many noble lives were killed from the new coronavirus infection hitting the world, and in a situation where overseas tourism to prevent the spread of disease and the decline in the service industry is causing a major blow to the national economy and trade, infection prevention is being done. It can be said that the importance of proper hand washing is even more important.
