DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. This rechargeable electric device includes a charger 1 and a device to be charged 2. The device to be charged 2 is driven by being charged, such as a cordless phone, an electric toothbrush, an electric razor, etc. Here, a cordless phone will be described as an example.

The outer shell of the charger 1 is composed of a first casing 3 whose upper surface is formed into a substantially circular end surface. On the upper surface of the first casing 3, there is a convex portion 4 having a shape such that the upper surface of a cylinder is closed at the center, and an annular wall-shaped fitted portion 5 having a constant height is provided on the outer peripheral edge. An engaging protrusion 6 is provided between the portion 4 and the fitted portion 5. Inside the first casing 3, the core 7 provided from the inside of the convex portion 4 to the lower side, and the core
A primary coil 8 as a charging section disposed around 7 and
A printed circuit board 9 provided with a large number of electronic components is housed therein, and a conductor portion of a power cord 10 drawn from the outside of the first casing 3 to the inside is connected to the printed circuit board 9.

The outer shell of the device to be charged 2 is composed of a second casing 11 whose side surface is formed to also serve as a handle portion and whose lower surface is formed into a substantially circular end surface. The fitting portion 12 is fitted to the fitting portion 5. Second
On the side surface of the casing 11 of the operation unit 13, the transmitter 14,
It has a receiver section 15, and an antenna section 16 for transmitting and receiving radio waves to and from other devices at its upper end. In addition, the lower surface of the second casing 11 has a concave portion that fits in the convex portion 4 at the center.
17 has a concentric groove 18 that engages with the engagement protrusion 6 at a position apart from the center by a predetermined distance. In addition, inside the second casing 11, there is provided a secondary coil 19 as a charged portion arranged around the recess 17, and a battery (not shown) for storing electricity from the secondary coil 19. is doing.

Next, the charging method of this embodiment will be described. When the mating part 12 is mated with the mated part 5, the concentric groove
Since 18 engages with the engaging projection 6 and the concave portion 17 fits into the convex portion 4, the device to be charged 2 can be attached to the charger 1 in a state in which it can rotate around the convex portion 4. That is,
The device to be charged 2 is put in the charger 1 only by fitting the fitting part 12 to the fitting part 5 in a desired orientation.

Further, at this time, since the secondary coil 19 is arranged around the primary coil 8 via the concave portion 17 and the convex portion 4, the charger 1 and the device to be charged 2 are in a chargeable state. Become. When current flows through the primary coil 8, the secondary coil 19
An induced current is generated in the battery, and this induced current flows into the battery and is charged. When charging of the battery is completed, the device to be charged 2 can be driven.

By the way, when the charger 1 or the device to be charged 2 is a non-conforming model, the fitted part 5 and the fitted part 12 are fitted together,
Alternatively, the protrusion 4 and the recess 17 cannot be fitted together, or the engagement protrusion 6 and the concentric groove 18 cannot be engaged with each other, so that the charging target device 2 and the charger 1 can be prevented from being mounted. As a result, charging from the primary coil 8 to the secondary coil 19 can be disabled.

As described above, according to the present embodiment, only by fitting the fitting portion 12 to the fitted portion 5 in a desired orientation, the device to be charged 2 is attached to the charger 1 and the primary coil 8 Since the charging of the secondary coil 19 is guaranteed from the above, the charger 1 and the device to be charged 2 can be easily attached.

Further, in the present embodiment, when the charger 1 or the device to be charged 2 is a non-conforming model, they are prevented from being mounted and charging from the primary coil 8 to the secondary coil 19 is disabled. Can be used safely.

In this embodiment, the convex portion 4 is provided on the charger 1 and the concave portion 17 is provided on the device to be charged 2. However, the convex portion 4 is provided on the device to be charged 2, and the concave portion 17 is provided on the charger 1. It may be provided. Further, the fitted portion 5 and the fitting portion 12, the engagement protrusion 6 and the concentric groove 18 may be replaced in the same manner as described above.

In the present embodiment, the charging section (primary coil
8) and the part to be charged (secondary coil 19) are of non-contact type, but may be of contact type by terminals. In this case, if the charging part and the charged part are provided on the center of the mounting part of the charger 1 and the device to be charged 2 or on a concentric circle separated by a predetermined distance from the center, when the device to be charged 2 is mounted on the charger 1. The charging from the charging section to the charged section can be reliably guaranteed.

[0024]

According to the rechargeable electric device according to the first aspect of the present invention, even if the charger and the device to be charged are mounted in a state in which they are rotated about the centers of their mounting parts, the charging part is charged to the charging part. Since the chargeable state is guaranteed, as a result, the degree of freedom in the mounting state of the charger and the device to be charged is increased, and the mounting of them can be easily performed.

In addition to the effect of claim 1, the rechargeable electric device according to claim 2 restricts the charger and the device to be charged in such a state that the charger and the device to be charged can rotate around the centers of their mounting portions. The chargeable state from the charging section to the charged section can be more surely guaranteed.

According to the rechargeable electric device of the third aspect, in addition to the effect of the first or second aspect, the charger and the rechargeable device can be attached to each other only by fitting the fitting part to the fitted part. So
It is possible to more easily attach the charger and the device to be charged.

In addition to the effect according to any one of claims 1 to 3, the rechargeable electric device according to claim 4 has a concentric groove and an engaging projection when the charger or the device to be charged is a non-conforming model. Since and cannot be engaged with each other, it is possible to prevent the charger from being attached to the device to be charged, and disable charging from the charging unit to the charging unit.
