As shown, the wire brake device of the electric clothes-hanger rod of the present invention includes a housing 1 in which a drive motor M is configured, and a pair of wires 5 wound and wound around both sides of the drive motor M; The two ends of the wire 5 are connected to each of the two brackets (4) and the two brackets (4) and a plurality of clothes hanger rods (2) through which the laundry is hanging and one side to the bracket (4) In this connected and the other side of the electric clothes drying rack consisting of X-shaped expansion link (3) coupled to the inner surface of the housing (1), the drive motor (M), the wire bobbin wound around the wire 5 is built up Insertion hole 11 inserted into the drive shaft M1 of the through hole in the center, the inner side of the rotating disk 10 formed with a plurality of sliding holes 13 formed with a locking piece 12 on the circumferential surface and the rotation The rotating disk is fastened to the sliding ball 13 formed on the peripheral surface of the disk 10 The stopper 30 which is slid in the outer direction of the rotating disk by the rotation of the 10 and the stopper 30 is located on one side of the stopper 20 and one side is fastened to the inner surface of the housing 1. It consists of.

In addition, the locking holes 20, the two locking pieces (21) which are respectively located on the circumferential surface of the rotary disk 10 to correspond to the sliding hole 13 formed radially inside the rotary disk (10) 21a, fastening holes 23 through holes respectively corresponding to the inner surfaces of the two locking pieces 21 and 21a, and the fastening holes 23 of the locking piece 21 are drawn into one side. After passing through the sliding hole 13 of the rotary disk 10 is fastened to the fastening hole 23 of the locking piece 21a of the other side to the two locking pieces 21, 21a of the rotating disk ( Two fastening pins 22 and 22a fixed to the sliding ball 13 of 10 are included.

In addition, the stopper 30 having one side fastened to the inner surface of the housing 1 is smoothly rotated by the driving force of the driving motor M of the rotating disk 10, and thus, the rotation of the rotating disk 10. It is preferable that the latch 20 fastened to the circumference is positioned within the range not to interfere.

The dry rod fall prevention safety device of the electric clothes dryer of the present invention configured as described above, when the clothes hanger rod is raised or lowered to hang or hang the laundry, the wire wound on the wire bobbin When unwinding or winding of the rotary disk 10 is naturally rotated in one direction by the speed set by the driving force of the drive motor as shown in Figure 5a, in this case the peripheral portion of the rotary disk 10 A plurality of fasteners 20 fastened are naturally rotated in accordance with the rotation of the rotating disc 10.

In addition, when the locking port 20 is rotated by the rotation of the rotating disk 10 is rotated along the rotating disk 10 and the position is changed downward, the fastening pin 22 of the locking port 20 22a are slid through the inside of the sliding hole 13 through which the inner side of the rotating disk 10 slides, and at this time, the locking holes 20 on both sides of the inner surface of the sliding hole 13, respectively. It is caught by the fastening pins 22, 22a of the locking hole 20 is rotated without being completely separated to the outside of the rotary disk (10).

That is, the fastening pins 22 and 22a, which are means for fixing the two locking pieces 21 and 21a of the locking hole 20, ride on the sliding hole 13 through which the rotating disk 10 is perforated. When the position of the locking hole 20 is the lower end side of the rotating disk 10, the locking holes 20 are locked from the outer side of the rotating disk 10 by being locked to the inner side both sides of the sliding ball 13 by sliding. When the position of the locking device 20 is opened and the position of the locking device 20 is the upper side of the rotating disk 10, the position of the locking device 20 is narrowed from the outside of the rotating disk 10.

Therefore, by the rotation of the rotating disk 10, the latch 20 is opened from the outer side of the rotating disk 10 to be narrowed again from the outer side of the rotating disk 10, the latch 20 is rotated When the point that is opened from the outside of the disk 10 is 0 ° when the positions of the rotation disk 10 and the locking hole 20 are vertical, the point that is out of the position of 90 ° from this 0 ° vertical point is opened. Since the stopper 30, which is provided on one side of the stopper 20, is rotated according to the rotation of the rotating disc 10, the stopper 20 rotates the stopper 20 shown in FIG. 5A. As close to the radius "a", the latch 20 is naturally rotated without interference of the stopper 30.

In this way, the stopper 20 that is naturally rotated without interfering with the stopper 30 is instantaneous to the rotation disc 10 when the wire is momentarily quickly released by the load of the clothes hanger rod when a motor failure or the like occurs. Acceleration force is generated and, accordingly, the momentary acceleration force acts on the locking hole 20 fastened to the circumference of the rotating disk 10 so that the locking hole 20 is shown in FIG. 5B. The outer portion is caught by the stopper 30 provided on one side of the locking hole 20 by moving away from the rotation radius "a", so that the rotating disk 10 is stopped, as well as the rotating disk 10 is built up. By stopping the rotation of the motor shaft M1 and the wire bobbins arranged on the motor shaft M1 temporarily, the wire hanger rods are prevented from falling as the wires are prevented from being released.

Therefore, even if a failure of the motor or the like occurs, the locking hole 20 is quickly released from the outer side of the rotating disk 10 by the momentary acceleration force, and thus the outer side of the locking hole 20 is caught by the stopper 30. As the laundry hanger rod is instantaneously lowered, it is possible to prevent safety accidents caused by hitting body parts such as the user's head.

In other words, the binding force of the wire bobbin is lost due to the failure of the motor, and the wire wound on the wire bobbin is quickly lowered by the load of the clothes hanger rod. The rotating disk installed on the shaft rotates rapidly to generate instantaneous acceleration force. Accordingly, the fastener is also quickly actuated by the centrifugal force due to the instantaneous acceleration force, thereby deviating momentarily from the rotation radius of the latch. The descent of the rod stops.

Figure 6 is a front view showing another embodiment of the dry rod fall prevention safety device of the electric clothes dryer of the present invention. As shown, at one side of the sliding hole 13 formed on the circumferential surface of the rotating disk 10, the noise prevention pad 14 to prevent noise during the rotation of the latch 20 is further fitted.

Therefore, when the locking hole 20 is configured on the circumferential surface of the rotating disk 10 and slid according to the rotation of the rotating disk 10 is positioned as the center point of the rotating disk 10, the locking hole 20 Even if the fastening hole 23 hits the sliding hole 13, the noise is reduced by the noise prevention pad 14, so that the laundry dryer can be driven in a quieter state.

As such, the safety device for preventing dry rod falling of the electric clothes dryer of the present invention is capable of various modifications in addition to those shown and described, and the embodiments to be modified are all rights of the present invention without departing from the scope of the present invention. It should be interpreted as being included in the scope.

As described above, according to the dry bar fall prevention safety device of the electric clothes dryer of the present invention, a rotating disk is installed on the drive shaft of the motor in which the wire bobbin on which the wire is wound is installed, and the locking disk is radially attached to the circumferential surface of the rotating disk. As it is further provided, by the normal driving of the motor does not interfere with the stopper provided on the inside of the housing, the laundry hanger rod of the drying rack is lowered quickly by the failure of the motor, etc. When the rotational disc generates an instantaneous acceleration force, the locking mechanism is caught by the stopper so that the rotation of the rotational disc as well as the rotation of the wire bobbin installed on the drive shaft and the drive shaft of the motor in which the rotational disc is built, are blocked. The wire is prevented from being loosened, and the lowering of the clothes hanger rod is blocked in advance. The effect of preventing users of the accidents caused by the inter-descent in advance is expected.
