The power cord locking device 100 of the vacuum cleaner according to the present invention is installed at one corner of the rear side of the main body 3 as shown in FIGS. 3 to 5 to supply external power to a motor (not shown) during cleaning. In order to fix the power cord P drawn out to the outside through the outlet 111 from the cord reel 52 until the end of the cleaning operation, or after the end of the operation, the operation of retracting and winding up the inside of the main body 3 is conventionally performed. It is possible to perform this as a button member 120 of a simple structure without the need to control as a complex structure.

That is, the power cord locking device 100 according to the present invention, as shown in Figure 3, is equipped with a button member 120 that can control the rotation of the cord reel 52 on one side edge of the main body (3) The accommodating part 110 is provided, and the accommodating part 110 is formed by recessing the inside of the main body 3 to a predetermined depth, and the cord reel 52 installed inside the main body 3 on the front side thereof. A power cord P wound around a predetermined length is provided with a through hole 111 so that the power cord P can pass freely according to the user's intention. It has a raised portion 113 protruding to be high.

And, the upper surface of the receiving portion 110 is provided with a plurality of hinge holes 112, such a hinge hole 112 of the mold hole 112c in which the mold falls out as shown in the A-A 'cross-section shown. The hinge rod (112a) of the circular cross section on the upper side is formed integrally between the two support ribs (112b) vertically.

In addition, the button member 120 mounted on the receiving portion 110 is snap-fit type to the hinge rod 112a of a predetermined length having a circular cross section on the lower surface corresponding to the hinge hole 112 of the receiving portion 110. By forming a plurality of hinge ribs 122 assembled with the hinge ribs 122, the hinge rods 112a can be freely hinged to the pivot axis so that the cord reel can be controlled by the button member 120. The hinge ribs 122 are free to slide in the directions of arrows B1 and B2 as shown in FIG.

In addition, the front of the button member 120 corresponding to the outlet port 111 formed in the accommodating part 110 is provided with a through-hole 121 through which the power cord P is drawn out and passed through. The upper and lower edges of the sphere 121 are provided with a plurality of guide ribs 123 extending toward the main body 3 while being inclined upward at an angle with respect to a horizontal plane, and at one side of the guide rib 123, the button member ( The stepped portion 123a which is partially cut to slide on the inclined surface of the ridge 113 formed on the front surface of the receiving portion 110 when the B2 direction is moved in the B2 direction, and the upper surface of one side of the button member 120 It is preferable to protrude the handle 124 to facilitate the user's operation during the sliding movement for switching the position in the B1, B2 direction.

The button member 120 suddenly bends the power cord P, which is in contact with the inner surface of the guide rib 123, in a U-shape to increase the frictional force at the contact portion, thereby temporarily stopping the power cord P. In order to be possible, the guide rib 123 is operated to form a state inclined at a predetermined angle upward with respect to the center of the outlet 111, while the automatic winding operation of the button member 120 or the power cord (P) At the time of forced withdrawal of the guide rib 123 and the center of the outlet 111 to minimize the frictional force generated in the contact portion with the power cord (P) to facilitate the inlet, outlet operation of the power cord (P) Make the same horizontal state.

The power cord locking device 100 of the vacuum cleaner according to the present invention configured as described above draws the power cord P built in the vacuum cleaner 1 to the outside in order to connect with an external power source, and then, when it is temporarily fixed, withdraws it. The power cord P can be fixed until the end of the cleaning operation. As shown in FIGS. 4A and 4B, first, when the user pulls the power cord P wound around the cord reel 52 to the outside, The height of the user's mounting of the power cord P by hand is significantly higher than that of the outlet 111 and the through-hole 121, and the button member 120 is in contact with the outer surface of the power cord P forcibly drawn out. Since the contact from the upper end of the through hole 121), by the external force of the user pulling the power cord (P) outwards, the button member 120 of the hinge 112, the hinge rib 122 is assembled Arrow as shown by pivoting axis of hinge rod 112a It is hinged in the C direction.

In this case, as shown in FIG. 4C, the guide rib 123, which was inclined upwardly at an angle with respect to the center of the outlet 111, is switched to a horizontal state, and the outlet 111 and the through hole 121 are Located on the same axis, and the power cord (P) drawn out while being in contact with the outlet 111 is maintained almost horizontal, at this time, the friction force generated in the contact portion is the coil spring built in the cord reel (52) Since it is smaller than the elastic force of (not shown), the power cord P can be easily taken out from the inside of the main body 3 to the outside.

On the other hand, when the user wants to perform the cleaning operation by fixing the power cord (P) drawn out to the desired length as it is, as shown in the figure, when the user releases the power cord (P), the power cord (P) The power cord P, which is released to the bottom surface by its own weight and releases the external force applied thereto, is automatically wound by the elastic restoring force of the coil spring (not shown) built in the cord reel 52. It is going to pull in part to the said main body 3 side so that it may be wound by (F).

At this time, since the frictional force is generated on the outer surface of the power cord (P) drawn in the automatic winding direction (F) and the inner surface of the guide rib 123 to form the through hole 121, the power cord (P) When the button member 120, which is hinged in the C direction and is free, is hinged in the D direction as shown in FIG. 3C, the end of the guide rib 123 is received in the receiving portion 120. When the button member 120 is hinged to a degree of contact with the front of the guide, guide ribs for guiding the power cord P to be introduced into the main body 3 through the through hole 121, as shown. Forming angle of 123 is formed to be inclined at a predetermined angle upward with respect to the floor surface, it is possible to naturally bend the power cord (P) in the shape of a bent sharply bent at the outlet 111 position.

In this case, the power cord P to be pulled into the automatic winding direction F by the coil spring of the cord reel 52 at the bending portion of the power cord P that is sharply bent in contact with the outlet 111 is stopped. Since enough friction force can be generated, a state in which the power cord P is pulled out as desired until the user finishes cleaning without a separate device for controlling the rotation of the cord reel 52 as in the related art. You can simply fix the position with.

On the other hand, when all the cleaning work of the vacuum cleaner 1 is finished and the power cord P drawn out is to be automatically wound and stored in the original reel to the cord reel 52, the locking operation of the power cord P is performed. When the user grasps the handle 124 of the button member 120 positioned as shown in FIG. 4C and pushes it toward the B2 direction of FIG. 3, which is the center side of the main body 3, as shown in FIGS. 5A and 5B. Since the hinge rib 123 of the 120 is assembled to allow the free sliding movement of the hinge rod 112a of the hinge 112, the stepped portion formed by being cut on one side of the guide rib of the button member 120 ( 123a is gradually moved on the inclined surface of the container portion 113 formed on the front surface of the receiving portion 110 while moving to the center side of the main body (3).

At this time, the container portion 113 is formed so as to increase the inclination angle toward the center side of the main body 3, the main body of the button member 120 assembled to enable the hinge operation on the hinge rod (112a) (3) The slide can be smoothly hinged in the direction of the arrow C as in the drawing operation of the power cord (P) while sliding to the center side.

The guide rib 123 is formed in the same horizontal state as that of the outlet port 111 by the hinge operation occurring at the same time as the sliding movement of the button member 120, and thus the bending portion of the power cord P at the outlet port 111 is formed. Since it is gentle, the friction force generated at the contact portion can be made smaller than the elastic restoring force of the coil spring built in the cord reel 52. Then, if the step portion 123a is maintained on the button member 120 while the inclined surface of the container portion 113 is raised so that the state of the guide rib 123 is maintained, the power cord P is The power plug at the tip touches the through hole 121 so that it can be automatically wound and stored in the cord reel 52 in the main body 3 until no further insertion is made. When the automatic winding of the power cord P as described above is completed, the button member 120 can be slid again to the initial state by sliding the button member in the direction of arrow B1.

According to the power cord locking device of the vacuum cleaner having the configuration as described above, the button member is provided with a drawer opening in the front of the receiving portion recessed in one corner of the rear of the main body, the hinge hole having a hinge rod of the circular cross section on the upper surface By mounting the hinge rib of the user, the user can pull out the power cord to the outside easily, and when the user releases the power cord, the user can pull the power cord by the guide rib of the button member operated by the hinge. Since the power cord can be temporarily fixed by bending rapidly at the contacting area, the necessity of the power cord locking device having a complicated structure as in the prior art simply ends the cleaning work with the power cord drawn out by the hinge operation of the button member. It can be maintained up to.

Then, when the user slides the button member toward the center of the main body, bending the power cord while switching the guide rib of the hinged button member to a horizontal state as the stepped portion of the guide rib rises to the inclined surface of the container portion formed adjacent to the outlet. By smoothing the accuracy, the friction force generated at the contact portion is smaller than the elastic restoring force of the coil spring, so that the drawn out power cord can be automatically and quickly introduced into the main body.

Accordingly, a simple structure for mounting a button member which can be hinged to the receiving portion formed on the rear of the main body is fixed to the drawer state to complete the cleaning work, and after use, by the hinge operation according to the sliding movement of the button member. By automatically storing the power cord inside the body, it is easy to use, while reducing the manufacturing cost, while improving the durability of the finished product, and the improved effect of minimizing the after-sale maintenance conditions (After Service) is obtained.
