However, in such a conventional laundry drying drum, since the separation distance of the drying bar where laundry can be widened is not wide, laundry is hardly ventilated due to contact between laundry when there are many laundry items, and laundry is hardly dried in summer or when humidity is high There is a concern that the laundry which is exposed for a long period of time in a wet state is placed in an environment where bacteria easily reproduce, adversely affecting odor and user's health.

In the case of a towel or a dish used in a bathroom or kitchen, it is used in a state of being hooked on a hook attached to a bathroom wall or a kitchen sink. In many cases, a towel or a dish is used after hanging it on the same hook. However, bathrooms and kitchens have a relatively high humidity in the indoor space, and it takes a long time for the towel and the cloth to dry completely.

Especially, in the case of the bathroom where the humidity is high and the ventilation is not good in the indoor environment, the towel can not be used when the towel is used, and since the towel is left wet for a long time, Hygienic problems may arise with the concern of.

 In the case of a kitchen, there is a problem that if the cloth is kept wet for a long time, it may cause a problem of secondary contamination of the food.

However, due to such hygiene problems, if the towel or dishwasher is used once and washed, environmental pollution due to frequent use of detergent may occur, and the towel may be easily worn out.
