Provide a drum washing machine. Here, the kimchi lactic acid bacteria fermentation treatment is made by coating the kimchi lactic acid bacteria fermented product or molding into a material containing the kimchi lactic acid bacteria fermentation.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are views illustrating an example of a drum washing machine according to the present invention, in which a drum washing machine forms an exterior, and an upper portion of the drum washing machine is suspended by a spring 4 inside the cabinet 2. A tub 10 having a lower portion and a lower portion supported by the damper 5, a drum 14 formed to be rotatable inside the tub 10 and having a plurality of through holes 12 through which washing water or foam flows in and out, A lift 16 mounted on the inner side of the drum 14 to lift the laundry and dropping the laundry at a predetermined height to mix the laundry, and a motor installed at the rear of the tub 10 to rotate the drum 14. And 20.

A cabinet cover 22 having an inlet through which laundry is introduced and drawn out in the center of the cabinet 2 is mounted as part of the cabinet 2, and the front of the cabinet cover 22 prevents the laundry from being separated through the inlet. The door 24 is installed so as to be openable and close, the control panel 26 for adjusting the driving of the washing machine is installed on the upper side of the cabinet cover 22, the cabinet cover to seal between the door 24 and the tub 10. A gasket 45 is provided between the 22 and the tub 10.

The top and bottom surfaces of the cabinet 2 are mounted with a top plate 28 and a base 30 as part of the cabinet 2, and under the top plate 28, washing water and detergents are provided inside the tub 10. A water supply hose 32, a water supply valve 34, and a detergent box 36 to supply water are built in, and an upper surface of the base 30 includes a drain pump 38 and a drain hose 40 for circulating or discharging the wash water. Is installed.

The present invention gasket 45, tub 10, detergent box 36, drum 14, lift 16, door 24, feed hose 32, feed valve 34, drain hose 40 And the kimchi lactic acid bacteria fermentation treatment to at least one of the drain pump 38.

Kimchi lactic acid bacteria fermentation treatment may be made by coating the kimchi lactic acid bacteria fermentation, such as drum 14, or by molding the drum 14 and the like containing a kimchi lactic acid bacteria fermentation.

The gasket 45 is not only for sealing between the tub 10 and the door 24, but also serves to cushion shocks from the tub 10 and the door 24, so that the gasket 45 is corrugated and wash water or Detergents can remain and become contaminated and, in severe cases, odor. By treating the kimchi lactic acid bacteria fermented product to the gasket 45, it is possible to protect it from contamination.

The tub 10 may leave a residue of foreign matter or detergent after washing, and the foreign matter or detergent thus left provides a good environment for mold and bacteria to propagate. The tub 10 can be treated with kimchi lactic acid bacteria fermentation product to protect it from contamination.

The detergent box 36 is a box in which a detergent is contained, and is a space in which a mold, bacteria, and the like can propagate by remaining as the detergent is solidified. By performing the kimchi lactic acid bacteria fermented product to the detergent box 36, it can be protected from contamination.

By treating kimchi lactic acid bacteria fermentation product to the drum 14, not only the antimicrobial activity of the entire drum washing machine can be maintained, but also the part which contacts the laundry can be given antimicrobial property to the laundry. However, since the drum 14 is mainly made of stainless steel, it is preferable to treat the kimchi lactic acid bacteria fermentation by coating rather than molding.

By carrying out the kimchi lactic acid bacteria fermentation treatment to the lift 16 whose contact strength with laundry is higher than the drum 14, antimicrobial activity with respect to laundry can be improved. Therefore, when it is examined from the viewpoint of increasing the antimicrobial properties of the laundry, it is possible to process the kimchi lactic acid bacteria fermentation product more effectively in terms of ease of manufacture and cost compared to processing the kimchi lactic acid bacteria fermentation product throughout the drum 20. . In addition, since the lift 16 is a member coupled to the drum 14 by screwing or the like, contamination of foreign matter, detergent, etc. may occur at a portion where the drum 14 and the lift 16 are coupled, and the lift 16 By performing the kimchi lactic acid bacteria fermentation product, the washing tank can be protected from such contamination.

As shown in FIG. 1, since the door 24 is not simply configured as a flat surface, washing water or detergent may remain at all times, and not only may cause bad smell when contaminated, The effect of this will be halved. By performing the kimchi lactic acid bacteria fermented product to such a door 24, it can be protected from contamination.

In addition, by treating the kimchi lactic acid bacteria fermentation product to the water feed hose 32, the water feed valve 34, the drain hose 40, and the drain pump 38, the drum washing machine as a whole is protected from contamination, and the kimchi flows into the flow path through which the wash water passes. By carrying out the lactic acid bacteria fermented product treatment, it becomes possible to impart antimicrobial activity to laundry and waste water flowing out. Since it forms a flow path, it is possible to provide antibacterial by installing a filter containing fermented lactic acid bacteria Kimchi.

The specific method of processing the kimchi lactic acid bacteria fermentation will be described later.
