Description

Clothes dryer{CLOTHING DRYER}

The present invention relates to a clothes dryer.

It is common for wet clothing to dry naturally by hanging it on a drying rack installed indoors or outdoors. However, this method is inevitably affected by the weather, and the window cannot be opened on days when the concentration of fine dust in the air is high, so there is a problem in that it cannot be sufficiently dried in an indoor room where ventilation is not properly performed.

Recently, in order to solve such a problem, a number of household dryers have been developed and sold.

However, conventional domestic dryers have a problem in that a wide installation space is required due to an enlarged device size in order to secure a clothing storage space.

In order to solve this problem, the present applicant has developed a laundry drying apparatus with free size adjustment. However, there was a problem that the clothing storage space was relatively reduced due to the Caesars-type height adjustment unit, and there was also a problem that the appearance of the device was limited to a square shape or a similar shape if the device was attempted to be made as compact as possible for the purpose of the patented invention. .
