Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to all electrical equipment that is driven by being plugged into a power outlet and supplied with power from a commercial power source.

BACKGROUND ART FIG. 29 shows an example of a vacuum cleaner as an example of a conventional electric device. FIG. 29A shows the state when the power plug 1 of the conventional vacuum cleaner 3 is inserted into the power outlet 2. Figure 29B shows the place where the power plug 1 is unplugged from the power outlet 2.In an ordinary household, cleaning the room is an essential daily task for housewives.However, the vacuum cleaner 3 does not connect the power plug 1 to the power outlet. If you are cleaning only one room, it is enough to plug the power plug 1 into the power outlet 2 in that room once, but when the room is large or you move from room to room, Each time, you have to move to the power outlet 2, bend down, grab the power plug 1 from the power outlet 2 located at the bottom of each wall, and carefully plug and unplug it.Furthermore, after cleaning is finished, move to the power outlet 2. Bend down and pull the power plug 1 from the power outlet 2 located at the bottom of the wall.
After grasping the vacuum cleaner 3 and carefully pulling it out, the user presses the retract button for the power cord of the vacuum cleaner 3, stows the power cord, and stores the vacuum cleaner 3 in a closet or the like.

Similarly, other electric devices 3 are used by inserting the power plug 1 into the power outlet 2 and carefully removing the power plug 1 from the power outlet 2 after use.

Problems to be Solved by the Invention As described above, when using a commercial power source to supply power to the electrical equipment 3, when using the electrical equipment 3, the power plug 1 should be carefully inserted into the nearby power outlet 2. After use, you must always move to the power outlet 2, reach out, grasp the power plug l with your hand, and carefully pull it out from the power outlet 2, which is extremely troublesome. They are often left as they are without being pulled out, and in areas where lightning frequently occurs, there is a risk that electrical equipment 3 may be destroyed or a fire may occur.

In addition, in the case of an electrical appliance 3 such as a vacuum cleaner, which is easy to carry and is often moved and requires frequent plugging and unplugging of the power plug 1, the user must move to the power outlet 2 each time, reach out his hand, grab the power plug 1, and pull it out. The thing is,
It was a very troublesome and hard work, and it was extremely dangerous because the user would tend to pull the power cord and try to pull out the power plug 1, which could cause damage to the power plug 1, breakage of the cord, or poor insulation.

It is an object of the present invention to eliminate the above-mentioned conventional drawbacks and to provide an electronic device that allows the user to reliably and safely unplug the power plug without having to move to the power outlet.

Means for Solving the Problems In order to solve the above problems, the present invention has a configuration in which the power plug can be disconnected from the power outlet and removed with a single touch by remote control from the main body of the electrical device. .

For example, by operating a starting means such as a switch or button on the main body of an electrical device, the driving means such as a plunger, motor, gear, or spring built into a power plug can be controlled by power supply, electric signals, wires, etc. The power plug can be easily removed from the outlet by remote control using a control/transmission means such as mechanical control using a power source, etc., or wireless control using light, electromagnetic waves, ultrasonic waves, or the like.

Also, unplug the power plug from the outlet (as a method, the power plug has a built-in push-out rod, and the push-out rod pushes the power outlet, or the two metal legs of the power plug retract into the power plug, or the push-out plate is removed). It has a built-in structure, and the push-out plate can be used to push the power outlet.

Specifically, by holding and fixing a plunger as a driving means and an extrusion rod that is integrated with the drive shaft of the plunger and protrudes to the same length as the metal terminal of the power plug in a position parallel to the metal terminal. A formed power supply plug, a motor, a male screw groove provided on the drive shaft of the motor, an extruded rod having a female screw groove screwed thereto and a protrusion for preventing rotation,
This is a plastic case with a slide groove that has a concave groove that engages with the protrusion for preventing rotation of the push-out rod.The push-out rod that pops out from the power plug is positioned parallel to the metal terminal, and the push-out rod is positioned parallel to the metal terminal so that it sticks out to the same length as the metal terminal. The power plug formed by holding and fixing the spring and the pushing rod that slides parallel to the metal terminal have a flange approximately in the center, and the flange holds the pushing rod when it is pushed in. This is achieved by a push-out rod equipped with a stopper claw to prevent the push-out, a recess in the plastic case to hold the stopper claw when the push-out bar is pushed in, and a power plug equipped with a stopper release air to release the stopper claw. do.

In addition, as a means of starting these by remote control, a switch or button, etc. dedicated to removing the power plug may be provided on the main body of the electrical device, separate from the cord winding button, or a switch or button, etc., may be installed on the cord winding button on the main body of the electrical device. Built-in or interlocked.

The four axes of the power line for power supply and the control line for driving the push rod constitute a power cord serving as a transmission means, and power supply and electrical control using electric signals are performed.

Furthermore, in order to further ensure that the power plug does not come off, the drive means can be strengthened by providing a second coil in the drive unit that generates a magnetic field in the same direction or in the opposite direction to the magnetic field generated by the plunger coil. The driving strength of the plunger can be increased (or the power plug removal mechanism can be driven in multiple ways, with the initial operation using commercial power supply and the additional supply of auxiliary power from a battery built into the electrical device or a capacitor, etc.). There is a method of operating the power plug removal mechanism multiple times.

In addition, the power plug is directly connected to the commercial power supply, and safety is especially important, so it is integrated with the drive shaft of the plunger made of magnetic material, and protrudes parallel to the same length from the center of the two metal terminals of the power plug. The entire exposed part is covered with an insulating material such as plastic resin to ensure insulation of the exposed part, and a terminal fixing groove for holding and fixing the L-shaped metal terminal, a guide groove for holding and fixing the power cord, and a metal terminal. The soldering for connecting the power cord connects and forms a processing gap, and a pair of cases is provided with inner walls, half of which are convex and the other half are concave, on the left and right sides, and the power supply section is placed outside of the inner walls. The power plug is formed by gathering and housing the power plug drop-off operation part inside and fitting the power plug to ensure internal insulation of the power plug.

Other applications include remote control using wires, as mentioned above, as well as portable switch boxes consisting of an electromagnetic wave or ultrasonic wave transmitter, an electromagnetic wave or ultrasonic wave receiver, and terminals for connecting electrical equipment power plugs.

The control/transmission means is composed of a metal terminal for connecting to an outlet and a power plug adapter consisting of various driving means, and remote operation by wireless control from a portable switch box is also possible.

Effect With the above configuration, when using an electrical device, the power plug is inserted into the power outlet as usual, but after using the electrical device, it is possible to remove the power plug from the power outlet by remote control from the electrical device itself. do.

The above action makes it easy to remove the power plug with a single touch and eliminates the hassle of work, thereby reducing the risk of leaving the power plug unplugged in the power outlet or pulling the cord to unplug it without holding the power plug. This not only prevents work, but also, in the case of vacuum cleaners, for example, leads to a significant reduction in the labor required for cleaning and the improvement of operational efficiency.
