Electric Sterilizing Cabinet for Tableware

The present invention relates to an electric dish sterilizer, and more particularly, to an electric dish sterilizer used in a kitchen of a restaurant army, a restaurant, and a restaurant, and sterilizing and drying dishes with hot air heated by electricity.

Sterilizers are devices used to destroy microorganisms such as bacteria on the surface of objects. They are used in various places such as hospitals and restaurants.

Sterilizers are classified into ozone sterilizers using plasma, ultraviolet sterilizers that directly destroy DNA of bacteria by irradiating ultraviolet rays generated from lamps, and heat sterilizers that kill bacteria by contacting hot air. .

Heat sterilizer is supplied to outside air and heated to about 80 degrees and then flows to disinfectant to kill bacteria existing on the surface of disinfectant. Sterilization performance according to the area, time and degree of contact with disinfectant and high temperature hot air This greatly depends on the feature.

In general, where a large number of meals are provided, such as in the military or school, a plate is used for convenience.

The plate is washed after use, dried on a quench table, and dried in natural air.

However, in the drying as described above, there is a problem that the bacteria parasitic on the plate is not sterilized.

Facilities for disinfecting and storing large amounts of tableware in group meals such as kindergartens, elementary schools, secondary schools, universities, hospitals, corporations, and military units are necessary. In order to be assured of food poisoning, diseases, and infectious diseases, the need for dish disinfection is emerging. .

In particular, in the case of a kindergarten or elementary school with low immunity, when a flu or food poisoning patient occurs among students, there is a problem of spreading through a plate.

There is a problem that the dishes are not dried well and are not well sterilized.

In addition, there is a problem in that the interior of the disinfection room is randomly opened air that is not sterilized is introduced into the interior.
