Generally, household electrical appliances are equipped with a plug that can be inserted through an electrical cord, and by inserting the plug into an outlet on the wall, power is supplied to the appliance, while the plug is connected to the outlet. I pulled it out and cut off the power supply. Attachment and removal of plugs to and from electrical outlets had to be done manually. However, if the above-mentioned electrical appliance is frequently used and unused (with the cord etc. stored), such as a vacuum cleaner, or if the outlet is located in a relatively difficult-to-reach location, the above-mentioned plug cannot be attached or removed. It's annoying.

The present invention was devised in order to solve the conventional trouble of attaching and detaching a plug to an outlet as described above, and in particular, to provide a convenient device that can easily disconnect a plug from an outlet by remote control. With the goal.

FIG. 1 is an explanatory view of a vacuum cleaner incorporating a plug removal device according to the present invention, and FIG. 2 is a partially enlarged view thereof. 1 is the vacuum cleaner body, 2 is the cord, and 3 is the plug. The plug 3 is provided at its tip with a conductive connecting blade 4 that is electrically connected to the main body 1 via the cord 2.
An insulator 5 is placed around the . 6 is a driving element made of a shape memory alloy;
becomes stiffer and curves when heated, and remains flexible when not heated. When using a vacuum cleaner, the drive element 6 is in a non-heated state and has flexibility, so when the plug 3 is inserted into an outlet (not shown), the drive element 6 becomes flat and stabilizes the state in which the plug 3 is inserted. maintain it. When storing the cord 2 inside the vacuum cleaner after using the vacuum cleaner, the switch 7 arranged on the side surface of the cleaner body 1 is pressed. Then, a current flows through the driving element 6 through a circuit (not shown) (2' is a wiring led from the main body 1 to the element 6, and a current for heating flows through the wiring 2'), and the driving element 6 is rapidly moved. heated. Therefore, the drive element 6 has increased rigidity and is curved, thereby allowing the plug 3 to be removed from the outlet. When the plug 3 is removed from the outlet, the power supply is stopped, and after the plug 3 is removed, the driving element 6 begins to cool down and returns to its original non-heated state.
Thereafter, when the switch 7 is pressed again, a well-known cord reel device provided inside the cleaner body 1 operates to wind up the cord 2. The vacuum cleaner with the above configuration is very convenient because by pressing the switch 7 provided on the vacuum cleaner body 1 twice, the plug 3 is removed from the outlet and the cord 2 is wound up. It is.

According to the present invention described above, the plug can be disconnected from the outlet by remote control, which is very convenient. Further, the device according to the present invention does not require a complicated drive mechanism for the above-mentioned remote control, so it is excellent in reliability and durability.
