Description

[0001] Air sterilization cleaning device [0002]

The present invention relates to an air disinfection and cleaning apparatus for sterilizing fruits and vegetables using an ionizer, and more particularly to sterilizing fruits and vegetables in a chamber by using a sterilizing function of radicals generated in an ionizer.

Further, the present invention relates to a cleaning device capable of removing radicals which may be harmful to a human body after sterilization cleaning for a more health-safe cleaning device, and which can be cleaned again with cleaning water.

Recently, as the consumption of organic vegetables and fruits has increased, interest in the hygiene status of these fruits and vegetables has become prominent.

Organic fruits and vegetables may increase the contamination of microorganisms, especially pathogenic bacteria, and fruits and vegetables have fine fleece on their surface, so they are not completely removed even when washed, May be harmful.

There are many ways to solve these hygiene problems.

One of them is an ultraviolet sterilizer, which is equipped with an ultraviolet lamp installed in the chamber to sterilize bacteria adhering to the surface of bacteria or vegetables in the air by ultraviolet irradiation.

However, since the use of such an ultraviolet sterilizer is limited to tableware, it is difficult to use it for sterilizing foods such as vegetables. Further, in the ultraviolet sterilizer described above, since only the portion directly irradiated with ultraviolet rays is sterilized, There is a fear that sterilization is not performed.

Another strong acidic sterilization device, which uses water to generate strong acidic water by electricity, is used to sterilize and clean vegetables with strong acid water.

However, such a strong acidic water sterilizing apparatus promotes corrosion by strongly acidic water, and when the vegetables and the like are washed in strongly acidic water, there are problems such as changes in the physical properties of vegetables and destruction of vitamins along the surface.

When strongly acidic water is used, strongly acidic water is discharged separately through an outlet, or strong acidic water is used after flowing alkaline water, and when alkaline water not used for sterilization is used, it has to be used in a separate container and used.

Another alternative is ultrasonic cleaning, which uses ultrasonic sound pressure and cavitation effects to clean vegetables.

However, such a cleaning method is used in the case of separating or washing fine foreign matter, but if the water in the cleaning net is not drained immediately after cleaning, the separated foreign matter adheres to the object to be washed again.

In order to solve the above-mentioned problems, the present invention attempts to sterilize all areas of vegetable surface by using air containing radicals generated from ionizer to increase the sterilizing effect and maintain the physical properties of vegetables and the like.

It is also intended to remove radicals which may be harmful to the human body remaining in the chamber after sterilization.

In addition, water washing equipment is added to sterilize and then to perform additional water washing to enhance the cleaning effect.

In addition, a dryer is added to provide convenience such as removing water after washing with water.

Preferably, the air sterilizing and cleaning device further includes a control unit connected to the circulation fan 400, the air flow path changing valve 200, the water pressure control valve 680, and the water level control valve 690 to control the cleaning process .

The air containing the radicals generated by the ionizer is directly contacted with the surfaces of vegetables and fruits, thereby enhancing the surface disinfection effect and improving the cleaning effect without affecting the properties of vegetables and fruits.

In addition, it is possible to remove the radicals by the use of the radical elimination filter, thereby preventing the possibility of harm to the human body due to radicals.

In addition, since the water washing device is added to remove foreign substances remaining on the surface of vegetables after sterilization, the cleaning effect can be enhanced.

In addition, since the drying air generated in the heater can be introduced into the chamber after the water washing to remove moisture remaining on the surface of the vegetables and the like, there is a convenience that the vegetables and the like can be immediately edited without a separate process for polishing the surface.
