Description

Cleaning and drying apparatus having a detachable plasma module

The present invention relates to an apparatus having a separable plasma module and capable of drying by a purifying wind after cleaning with sterilizing water.

Because people do everything with their hands, there are always various harmful bacteria and viruses on their hands.

Therefore, the need for personal hand hygiene management has been raised, especially in schools where group meals are provided, including facilities used by many unspecified people such as restaurants, hospitals, research institutes, rest areas, convenience stores, pubs, and entertainment establishments such as karaoke rooms. Even before meals, in kindergartens, playrooms, etc., good hand hygiene is required.

In general hand hygiene, you can remove various germs remaining on your hands just by washing with soap under running water, but the reality is that you cannot wash your hands immediately after touching objects or doing work. It is always exposed to us.

In particular, as infectious diseases such as swine flu, MERS, and SARS, as well as the corona virus that are currently prevalent in Korea as well as around the world, spread terribly due to infection through hand contact as well as droplets through people's mouth, it is necessary to wash and disinfect hands. Social interest is growing significantly.

Therefore, as a basic measure to prevent infectious diseases caused by hand contact, many places used by unspecified people, including masks, are essential to provide hand sanitizer so that people entering and leaving can use the hand sanitizer.

This hand sanitizer is a dispenser pump attached to the container, and many people who use it pump the required amount of disinfectant to discharge the disinfectant by lifting the container itself or pressing the lever with their hands. As a result, it can become infected, and frequent use of the disinfectant solution has a problem in that there is a possibility of causing skin reactions such as rash, inflammation, and itching by drying the user's hands with alcohol.

In addition, if the user can wash their hands, washing their hands with soap containing a surfactant instead of hand sanitizer is effective in preventing infectious diseases. However, solid soap requires direct contact for use, and liquid soap also has a problem in that it is infected through hand pressing the lever for dispensing.

In addition, if you wash your hands and dry them in the wind, secondary contamination of bacteria or viruses may be caused from dust in the fan, duct, and filter of the dryer.

The electrolysis module 180 is a tank of about 0.3 to 1 liter, and insoluble electrodes (Dimensionally Stable Electrode, DSE) of the anode and the cathode for electrolysis are installed therein.

The insoluble electrode refers to an electrode material in which titanium is coated with platinum, iridium, ruthenium, etc., which are noble metal oxides, and has a characteristic of improving electrical conductivity, but has a problem of poor durability.

Accordingly, the insoluble electrode of the present invention may be an insoluble electrode with improved durability through surface treatment, coating, and heat treatment processes.

As the tap water introduced into the electrolysis module 180 is electrolyzed, dissolved chlorine is converted into hypochlorous acid (HOCl).

Hypochlorous acid (HOCl) has a high sterilization power that can kill 99.99% of bacteria. Water containing hypochlorous acid (HOCl) becomes sterile water (50).

One side of the liquid flow path 230 is connected to the electrolysis module 180 , passes through the horizontal part 130 and extends to the liquid outlet 150 .

The generated sterilizing water 50 is sprayed from the liquid outlet 150 through the liquid flow path 230 in a spray manner. Hand washing is performed for several seconds to several tens of seconds, and the control unit 250 shuts off the valve 170 according to the output of the sterilization water sensor 260 .

Then, wet hands are moved to both sides of the faucet 100, respectively. Then, the purification wind sensor 270 detects the hand and outputs it to the control unit 250 . The control unit 250 operates the fan 240 and the plasma module 200 .
