The present invention relates to a lifting type laundry drying rack, and more specifically, in order to dry a laundry, in the process of hanging out the laundry in a wet state on a ceiling or a wall of the laundry drying space or collecting the dry laundry from the hanger. The height of the hanger to allow the user to arbitrarily manipulate the laundry manager to lift the laundry as well as to increase the utilization of the laundry drying space more.

In general, laundry drying racks are mainly used in homes or laundry, and are used to dry laundry including water-wet clothing in the sun or wind during the washing process. Traditionally, laundry lines have been used to dry laundry.However, as more modern houses and apartments in apartments, such as apartments in urban areas, become more common, there is no room for hanging clothes. Laundry racks that can use the narrow space of the more efficiently appeared.

As described above, a stand-up laundry rack that can be placed on the floor of the interior and exterior space replaces the clothesline, and in most homes, the frame of the main body can be extended or folded on both sides. One type of stand-up laundry dryer was brought to a degree.

On the other hand, as the construction cost of the house rises more and more, the need for more efficient use of the space of the building is being felt, and various ways of reducing the space required for drying laundry are being proposed. It is a technology disclosed by the Korean Intellectual Property Office (see Publication No. Sec.1995-0003200 and Practical Publication 94-0006393), and the electric laundry dryers configured to lift the hanger attached to the ceiling and a plurality of 'X' shaped members are arranged in series. Some of the results are bellows laundry dryers configured to attach to the ceiling (see Application No. 10-2001-003579) and to the wall (see Practical Publication 20-0205020), forming a Zarabar as a whole.

By the way, in the case of the electric laundry dryers, one of the above examples is configured to be elevated in the state where the hanger is attached to the ceiling, but the overall shape of the hanger forms a rectangular shape with a long length in the longitudinal direction for efficient use of space. There was a limit.

In addition, in the case of the bellows type laundry drying rack, which is another example, a plurality of "X" shaped members are formed in a relatively complicated structure so that they can be folded through the hinges. In addition, even if a failure occurs in any one of the hinge portion, there was a problem such as a problem in the overall folding system.

The present invention has been devised to solve the above-mentioned problems. To dry the laundry, the laundry is placed on the ceiling or the wall of the laundry drying space. It is an object of the present invention to provide a lifting laundry drying rack that enables the user to arbitrarily manipulate the height of the hanger during the collection process, thereby reducing the labor of the laundry manager and increasing the utilization of the laundry drying space.

In addition, another object of the technique according to the present invention is to form a circular or polygonal shape of the hanger on which the laundry hangs for more efficient use of the laundry drying space in the center of the hanger in a round concentrated form based on the center of the hanger The purpose is to make it possible.

In addition, the technique according to the present invention has an object to provide a lifting laundry drying rack that can be made more compact by reducing the volume occupied by the components required to drive the hanger when not using the laundry drying rack.
