Description

Dishwashing rack with sterilization function {TABLEWARE DRYER RACK WITH STERILIZING FUNCTION}

The present invention relates to a dish drying rack equipped with a sterilization function, and more particularly, to provide a space for drainage and aeration, and to dry dishes after washing dishes and sterilize the tableware while harmless to the human body in the direction of the dishware The present invention relates to a dish dryer having a sterilization function capable of disinfecting dishes by sanitizing safely.

Generally, the dish dryer is a kitchen utensil that allows dishes to be dried by naturally dropping water attached to the dishes by placing dishes such as rice bowls or plates. It is installed on the wall around water polo.

The dish drying rack is composed of a main body integrated with a wire arranged vertically and horizontally so that the tableware can be mounted, and hook members installed on both side surfaces of the main body so as to be fixed to the lower side or the wall of the upper cabinet. However, the conventional dish dryer with a wire structure provides only a function for drying the tableware's moisture, and does not provide a separate sterilization function, so when the dishes are poorly placed or poorly placed, the bacteria propagate in large quantities. There was a hygienic problem that could be.

In the related art, an ultraviolet sterilizer has been disclosed in which a mounting space is formed inside an openable enclosure and an ultraviolet lamp is installed on the upper part to sterilize and dry the dishes stored therein.

However, the dishes must be moved several times because the dishes, which have been washed in the kitchen sink, should be placed on the shelves to be sterilized in a UV sterilizer with some water removed. There was a hassle. In addition, by using ultraviolet rays having a wavelength range of 200nm to 370nm, bacteria having DNA or RNA can be effectively removed, but when the ultraviolet rays having such wavelength bands leak to the outside, skin aging, skin damage, DNA deformation and skin cancer may occur. There was a problem that could be.

In addition, when a dish sterilizer using ozone is generally used, there is a problem in that drying efficiency is limited while sealing the dish sterilizer due to carcinogenic effects due to ozone harmful to the human body in addition to the sterilizing effect due to ozone.

In addition, the tableware is placed on the shelf in such a way that the internal water is drained, but since the ultraviolet lamp emits downward from the upper position of the inner space, most of the ultraviolet light is irradiated only on the outer surface of the tableware. There was a problem that the interior is not properly sterilized.

Moreover, the sink of the kitchen is often in contact with water so that bacteria or molds can be easily reproduced, but conventional ultraviolet sterilizers and ozone sterilizers are sterilized only in sterilization spaces, so that many germs are around the sink. There was a problem that can not sterilize the sink.
