Abstract

PURPOSE:To prevent poor drawing-out or poor take-up a cord by arranging a cover body which has its shaft center at the cord outlet part of a body case so as to be freely turnable toward the inside of the body or toward the outside of the body. CONSTITUTION:When a cord 8 is taken up, a cover body 10 turns from the condition A to the condition B in the inside of a body case 1. In the condition A, since the cover body 10 abuts on the cord 8, a braking is added to the cord 8 at the time of starting of take-up when the rotating speed of a cord reel is highest, and the take-up speed of the cord 8 is reduced. Thus, the cord 8 is prevented from being swelled out so much by the force of inertia due to the speed in the inside of the body case, and is taken up in good order on the drum 3b of a cord reel 3. Accordingly, next, when the cord is drawn out, since the cord 8 wound around the drum 3b is drawnout in order from the outside to the inside, poor drawing-out or impossibility of drawn-out of the cord due to entanglement can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner having a cord reel winding device.

2. Description of the Related Art As shown in FIGS. 7 and 8, a conventional vacuum cleaner having a cord winding device has a cordry/L'22 inside a main body case 21. The cord 24 was wound around the drum part 23 of the drum. 2
6 is the cord reel wall surface of Cordry/l/22.

2e is a cord outlet of the cord 24 of the main body case 21.

Problems to be Solved by the Invention However, in such a structure, when one cord 24 is wound toward one side, as shown by the arrow in FIG. Two to three turns of the stacked cord 24 fall down toward the side with the smaller cord winding diameter, and end up overlapping the cord 24 that has been wound up later, resulting in their positions being reversed. In this case, when the user pulls out the cord 24 from the main body case 21, the cord 24 becomes tangled and cannot be pulled out. This is because the speed at which the cord 24 is wound up is fast because it is necessary to wind it up to the tip of the cord 24, which causes the above-mentioned problem. Also, because of its high speed, code 24
In some cases, the cord does not come into close contact with the drum portion 23 of the cord reel 22 and swells, which causes the cord to become tangled.

Furthermore, as shown in FIG.
When the cord 24 is wound on the wall surface 25 of the drum section 22, the outer diameter of the cord 24 becomes partially large, and the cord 24 hits the inner wall of the main body case 21 before the cord 24 is completely wound. This often caused problems with cord winding.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a vacuum cleaner that simultaneously solves the problems of cord pulling-out and cord-winding problems.

Means for Solving the Problems and In order to achieve the above objects, the present invention has an axis at the exit portion of the cord from the main body case, and a lid body is disposed rotatably from the inside of the main body to the outside of the main body. It is.

Further, in order to achieve the above object, a lid body is provided at the cord outlet section, which is biased by a spring or the like and rotates toward the inside of the main body.

Further, a lid is similarly provided at the cord outlet portion, which is biased by a spring or the like and rotates from the main body side to the outside.

By means of the first means described above, when the cord is wound, the lid hits the cord in the cord reel chamber inside the main body, the winding speed of the cord is weakened, and the cord is aligned with the drum part of the cord reel. It will be rolled up in an orderly manner. That is, this prevents the cord from getting tangled when the cord is pulled out, thereby preventing cord pulling failure.

Moreover, by winding the cord in an orderly manner, the cord winding diameter can be reduced, and the outermost diameter of the wound cord can be prevented from coming into contact with the main body case and not being able to wind the cord.

Further, even if the cord reel swells up in the cord reel chamber without being tightly wound around the drum, the lid hits the cord and the cord is pushed toward the drum and wound in an orderly manner. Therefore, this also provides the same effect as above.

Furthermore, since the lid of the cord outlet section also rotates toward the outside of the main body, even if the cord becomes tangled, the cord outlet is wide and can be easily pulled out.

Further, according to the second means, in addition to the effect of the first means, since the lid body is biased by the spring, the contact with the door can be strong and constant, and the spring Depending on the strength of the winding speed, the winding speed can be strongly reduced.

This makes it possible to more reliably prevent cords from becoming tangled.

Furthermore, according to the third means, in addition to the effect provided by the first means, the lid body is structured to be substantially perpendicular to the main body case so that it does not rotate any further inward on the main side. will not enter, making it highly safe. Furthermore, it is possible to prevent dust from entering the cord reel chamber and adversely affecting electrical connections.

Example Examples thereof will be described below with reference to the drawings.

1 to 4, reference numeral 1 denotes a partition wall that separates the electric blower 2 side from the Cordry/l/31Jl11, and is sandwiched and fixed between the upper main body case 4 and the lower main body case 6. e is code! One end of the rotating shaft of J-1v3 is fixed to the bulkhead 1 with a screw, and the other end is held by a rig formed on the upper 4 and lower 6 parts of the main body case. 7 is a spiral spring that urges the Cordry/L/3 in the winding direction of the cord 8, one end of which is a spring fixing groove 6a provided in the rotating shaft 6, and the other end of which is a spring fixing groove provided in the Cordry~3. It is fixed with ribs 3a. 3b is a drum around which the cord 8 is wound. Reference numeral 9 denotes a cord exit hole provided under the main body case, and has a lid 10 for closing the cord exit hole 9. This lid body 10 has a rotating shaft 10a, one end of which is held by the partition wall 1, and the other end supported by the lower body case 6. Further, this lid body 10 has a structure that almost blocks the cord exit hole 9.

11 is the brake lever, code! The brake roller 13 energized by the spring force of the brake lever spring 12 simultaneously contacts the outer circumferential surface of J-A/3 and the brake surface 1a provided on the bulkhead 1, thereby causing the code U-/l.
/3 rotations are fully braked. 14 is a brake button energized by a spring 16. By pressing this down, the brake lever 11 rotates and the brake roller 13 moves to the code! The brake is released away from the outer peripheral surface of J-#3, and the cord 8 is wound up. Further, 16 is a spring holding plate fixed with two screws, and 8a is a companion cord plug that is integrated with the cord 8.

In the above configuration, when winding the cord 8,
The lid body 1o rotates from state A to state B within the lower main body case 6. In state A, the lid body 10 comes into contact with the cord 8, so the brake is applied to the cord 8 at the point when the rotation speed of the cordry/I/3 is the fastest at the beginning of winding, and the speed at which the cord 8 is wound up is reduced. is weakened.

Therefore, Cord 8 does not swell up much due to inertia due to speed inside the main body case, and Cordry / l / 3
are rolled up in an orderly manner onto the drum 3b. Therefore, when the cord is pulled out next time, the inner cords are pulled out sequentially from the outside of the cord 8 wound around the drum 3b, so it is possible to prevent cord pulling failures in which the cords 8 become entangled with each other and cannot be pulled out.

Also, because of this, when the cord 8 is completely wound up, its outermost diameter is small, so the cord 8 comes into contact with a part of the upper body case 4 or the lower body case 6, and the cord 8 cannot be wound up. It is also possible to prevent cord winding defects such as cord winding.

In addition, if the cord 8 is not tightly wound around the drum 3b of the cord reel 3 and swells as shown in state C, the lid body 1o has moved to state B, so the cord 8 is hit. It is pushed toward the contact drum 3b and wound up in an orderly manner. Therefore, in the same way as described above, it is possible to prevent cord pull-out failures and cord winding failures.

Next, even if the cord 8 were to become tangled, the lid 1o would also rotate outward from the lower body case 6, so the cord outlet 9 would be widened and the cord 8 would not get caught at the cord outlet e like in the past. This eliminates the problem of being unable to withdraw the money because it is lost.

Next, another example of the structure of the lid body 1o will be described.

In FIG. 6, 17 is a spring attached to the rotating shaft 10a of the lid body 10. This spring 17 allows the lid 1o to be pressed against the cord leaf L/3 side of the rib 18 on the lower body case 6. Therefore, when the cord 8 is wound up, the lid body 10 contacts the cord 8 in state D, but
Because the contact is strong due to the force of the spring 170, and the strength of the spring allows the contact to be made in a stable state,
It becomes possible to strongly and consistently reduce the winding speed of the cord 8. This makes it possible to more reliably prevent the cord 8 from becoming tangled.

Next, another embodiment will be described.

In FIG. 6, the lid 1o is pressed against the outside of the rib 18 of the lower body case 6 by a spring 17, and is rotatable in the outside direction. For stiffness, lid body 1
o does not enter the main body case, and the user cannot put his/her hands or fingers into it, so there is no risk of electric shock, etc., and stability is improved.

Further, it prevents dust and the like from entering the main body case, prevents it from casting a negative influence on electrical connections, etc., and improves durability.

According to this structure, since the cord 8 is brought into contact with the lid 1o in the state D, the same effect as in the second embodiment can be obtained, and the cord outlet portion 9 can also be widened as in the first embodiment. Therefore, even if the cord 8 becomes tangled, it can be easily pulled out, and the cord can also be effectively prevented from being pulled out incorrectly.

Effects of the Invention As described above, the present invention has an axial center at the exit portion of the cord from the main body case, and a cover body is disposed so as to be rotatable to the inside and outside of the main body, thereby reducing the cord winding speed. At the same time, since the cord is prevented from swelling, becoming entangled, and getting tangled, failure to pull out the cord is prevented. Furthermore, since the cord is tightly wound around the drum, the cord does not come into contact with the main body case, thereby preventing cord winding failure.

In addition, the present invention provides a cover at the cord outlet section that is biased by a spring or the like and rotates toward the inside of the main body, thereby reducing the cord winding speed more reliably, eliminating cord entanglement, and preventing the cord from getting tangled. This can prevent defective drawers.

Furthermore, according to the present invention, the lid body is biased by a spring or the like, rotates outward from the main body side, and is locked in a substantially vertical direction, which prevents hands and fingers from entering the cord reel chamber, improving safety. Improved. In addition, there is no intrusion of dust, etc., and adverse effects on electrical connections are prevented, resulting in improved durability.
