Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to an electric appliance with a cord reel, and specifically relates to an improvement in a winding stop structure for an electric cord wound on a cord reel.

(B) Prior Art In general, hand-held electric appliances such as vacuum cleaners and hair dryers have an electric cord 2 attached to the appliance body 1, such as the hair dryer shown in FIGS. 1 and 2.
A cord reel 3 is installed inside the body to wind it up using an elastic return force, and a cord reel 3 is installed on the outer wall of the main body.
a stopper 4 for stopping the winding of the
It is provided with a cord extraction hole 5 through which an electric cord (hereinafter referred to as a cord) passes, and into which a plug 6 at the tip abuts from outside the main body 1. When using the electric appliance, the user pulls the plug 6 at the tip of the cord, rotates the cord reel 3, and pulls the cord 2 out of the main body 1 through the pull-out hole. On the other hand, when storing the cord in the main body 1, the stopper 4 is released and the cord reel 3 is rotated elastically, that is, the cord is wound up.
Wind up. At this time, the plug 6 at the tip of the cord came into contact with the outer wall surface of the main body around the cord pull-out hole 5, stopping the cord reel winding operation.

However, with this method, the elastic force of the cord reel 3 is set so that even if the cord 2 gets caught in the cord pull-out hole etc. when winding the cord, the elastic force of the cord reel 3 is set so that the cord 2 can be wound smoothly. It is often rolled up. In this case, the plug would jump up and hit the user's hand or collide with the vicinity of the cord pull-out hole, which could damage the plug and pose a safety problem.

(c) Purpose of the invention This invention was created in view of the above circumstances.
This is intended to prevent the plug at the tip of the cord from hitting the hand or against the outer wall of the instrument body around the cord extraction hole when the cord is wound up.

(d) Structure of the invention In an electric appliance with a cord reel, which is equipped with a cord reel for winding up an electric cord by elastic return force, the tip of the electric cord pulled out from the cord reel outside the body is attached to the outer wall of the electric appliance body. A plug locking means for locking the plug of the electric cord, and a cord reel winding stop means for stopping the winding operation of the cord reel near the locking means, and the plug of the electric cord is locked by the locking means. This electric appliance is equipped with a cord reel, and the plug is configured to press the stop means to release the stop when the stop means is stopped.

(e) Examples This invention will be described in detail based on examples shown in the figures below. Note that this invention is not limited to this.

FIG. 3 shows the overall structure of the hair dryer 7,
Reference numeral 8 denotes a hair dryer body, in which a heating element 9, an electric blower 10, and an electric blower fan 11 are arranged in this order from the front. Reference numeral 12 designates a handle of a hair dryer that houses a cord reel 13 for winding up an electric cord 15, and has a cord pull-out hole 14 formed at its lower end. Reference numeral 22 denotes a winding spring for the cord reel, which is energized in the winding direction of the cord reel 13.

Furthermore, as shown in FIGS. 4 and 5, the handle 12 is provided with a recessed plug accommodating part 17 for storing and locking the plug 16 at a position corresponding to the lower part of the cord reel on the rear surface, and the cord reel is wound in this accommodating part. A push button 18 for stopping is provided protrudingly. This push button extends from its front end within its body 8 and
3 Inverted L-shaped stopper cam 19 that comes into contact with the rear surface
This stopper cam is biased rearward by a spring 20 so as to stop the winding operation of the cord reel 13. On the other hand, the plug 16 is placed in the plug storage part 1 on the side.
A protrusion 21 that presses the push button 18 when stored in the case 7 is provided in a protruding manner.

Next, a method of winding up the cord 15 using the hair dryer 7 having the above configuration and stopping the winding rotation of the cord reel 13 will be explained.

First, in order to use the hair dryer 7, the plug 16 is taken out from the plug storage part 17, the stopper cam 19 is brought into contact with the rear surface of the cord reel 13, and the winding rotation of the cord reel 13 is stopped. Then pull the plug 16 and cord reel 1
3 is rewound and rotated, and the cord 15 is pulled out from the pull-out hole 14.

Next, after using hair dryer 7, use code 1.
5 in the handle 12, the plug 16 is inserted into the plug storage part 17 and locked. Then, press the push button 18 with the protrusion 21 of the plug and remove the stopper cam 19 from the rear surface of the cord reel 13.
The cord reel 13 is wound and rotated by the elastic restoring force of the spiral spring 22, and the cord 15 is wound up. At this time, when the cord 15 between the cord pull-out hole 14 and the plug storage portion 17 becomes tensioned, the cord reel 13 stops its rotation.

By configuring the hair dryer 7 as described above, it is possible to prevent the plug at the tip of the cord from hitting your hand or colliding with the outer wall of the main body around the cord extraction hole when winding the cord. It is possible to prevent damage and improve safety. As the cord reel winding stop means, in addition to the button that is pressed and retracted when the plug is locked, it is preferable to use buttons that move horizontally or rotationally when the plug is locked. Can be mentioned.

(f) Effects of the invention This invention provides a plug locking means and a cord winding stop means in the main body of an electric appliance with a cord reel, and releases the stop of the stop means when the plug is stopped. When winding the cord, the plug at the end of the cord can be prevented from hitting the hand or colliding with the outer wall of the device body, thereby preventing damage to the plug and improving safety. be.
