Abstract

A washing drying rack includes a plurality of securing hangers disposed at set intervals either transversely or longitudinally on a drying rack frame; a plurality of free-moving hangers which are formed below the fixed hangers in a number corresponding therewith, are link-connected with the corresponding fixed hangers, and perform a swinging motion using the fixed hangers as pivot shafts; and a drive means which generates power for the free-moving-hanger swinging motion.

First claim

The invention claimed is:

1. A washing drying rack comprising:
a plurality of fixed hangers horizontally or vertically arranged on a drying rack frame at regular intervals;
a plurality of movable hangers formed below the fixed hangers in the same number as the fixed hangers, the movable hangers being connected with the fixed hangers by the medium of movable frames and performing a swing motion around the fixed hangers as pivot axes; and
driving means for generating driving power for the swing motion of the movable hangers.

2. The washing drying rack according to claim 1 , wherein the fixed hangers are rotatably restricted to both ends of the drying rack frame.

3. The washing drying rack according to claim 1 , wherein each of the movable hangers is connected with the neighboring movable hanger through a link bar in an interworking manner.

4. The washing drying rack according to claim 1 , wherein all of the movable hangers perform the swing motion by just one driving means.

5. The washing drying rack according to claim 4 , wherein the driving means is any one selected from a rack-and-pinion type driving means, a ball-screw type driving means, and a linear cylinder type driving means.

6. The washing drying rack according to claim 5 , wherein the driving means is controlled in right and left rotation speed or in forward and reverse rotation speed.

7. The washing drying rack according to claim 4 , wherein the driving means is a link-type driving means comprising: a driving motor; a driving link mounted on a driving shaft of the driving motor in an eccentrically rotatable manner; and a driven link, a free end of the driving link being connected with a connection link located at the front end by the medium of the driven link.

8. The washing drying rack according to claim 4 , wherein the driving means is a cam-follower type driving means comprising: a driving motor; a cam rotatably mounted on a driving shaft of the driving motor; and a sliding bar to which front ends of the movable frames are pivotally connected at regular intervals, the sliding bar having a contact portion getting in contact with the surface of the cam.

9. The washing drying rack according to claim 8 , wherein a spring supporter is disposed at a point which is spaced apart from the contact portion of the sliding bar at a predetermined interval, and a spring is interposed between the spring supporter and the contact portion so as to provide restoring force by movement of the sliding bar.

10. The washing drying rack according to claim 8 , wherein the driving means is controlled in right and left rotation speed or in forward and reverse rotation speed.

11. The washing drying rack according to claim 1 , further comprising:
a load sensor adapted for outputting a command to stop the operation of the driving means or to operate the driving means in a reverse direction by changing a flow of electric current when a load exceeding a predetermined power to the movable hangers or the fixed hangers is sensed.

12. The washing drying rack according to claim 1 , wherein the fixed hangers and the movable hangers are hollow pipes having spray holes or slit type injection nozzles, and
further comprising:
a blower adapted for providing dry air to the inside of the fixed hangers and the movable hangers which are the hollow pipes.

13. The washing drying rack according to claim 12 , wherein strength of drying air provided through the blower is controlled by stages.
