Description

Plasma sterilizing apparatus for drain}

The present invention relates to a plasma sterilization device, and more particularly, to a plasma sterilization device for drains that sterilize and deodorize using plasma discharge.

The sink is equipped with a drain hole through which used water flows, and can wash the human body or objects by flowing water, such as a kitchen, laundry, and toilet. Hygiene management is important for the sink.

It is very important to sanitize the kitchen sink in which food residues are generated, especially during cooking and washing dishes, because food residues can cause bacteria to multiply and odor.

Accordingly, various methods have been proposed to perform sterilization and deodorization treatment in a drain.

Urea is injected into the urea to sterilize it.

On the other hand, in the prior art 1, since the sterilization deodorization port is attached to the outside of the sink, it may interfere with the user's operation, which may be cumbersome in use. In addition, the sterilization effect may be inferior to that of copper and silver of the main body and the lid being ionized and directly sterilizing the water.

In addition, since the prior art 2 is used by being connected to one side of the bucket, it is difficult to install and compact design, and a differential pressure may occur in the drooping structure.

In addition, since ozone is directly injected and used, a lot of attention needs to be paid to the management of ozone that may be harmful to the human body.

Thereafter, the gap adjusting unit 150 has a vertical gap based on the calculated horizontal gap (S1150).

For example, if the calculated horizontal spacing is less than 2 mm, the vertical spacing may be adjusted to 2 mm. In addition, if the calculated horizontal spacing is 2 mm to 4 mm, the vertical spacing may be adjusted to 3 mm, and if the calculated horizontal spacing exceeds 4 mm, the vertical spacing may be adjusted to 4 mm.

Depending on the embodiment, the plasma sterilization apparatus 10 may also adjust the voltage applied to the high voltage generator 110 based on the horizontal and vertical spacings (S1360).

For example, if the calculated horizontal spacing is less than 2 mm, the vertical spacing is adjusted to 2 mm, and a voltage of 4.5 kv may be applied to the high voltage generator 110. In addition, when the calculated horizontal spacing is 2 mm to 4 mm, the vertical spacing is adjusted to 3 mm, and a voltage of 6.8 kv may be applied to the high voltage generator 110. In addition, when the calculated horizontal spacing exceeds 4 mm, the vertical spacing is adjusted to 4 mm, and a voltage of 9 kv may be applied to the high voltage generator 110.
