BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on preferred embodiments with reference to the drawings. The dimensions of the members in the drawings are appropriately enlarged or reduced for easy understanding.

FIG. 1 shows a schematic configuration of a storage box 10 according to an embodiment of the invention. In this embodiment, the storage box 10 is arranged inside the toilet room 100 . The toilet room 100 is a relatively small space partitioned by walls 102, a floor 104, and the like.

A toilet device 30 is arranged on the floor 104 of the toilet room 100 . The toilet device 30 includes a toilet bowl 32 , a toilet seat 34 , a toilet lid 36 and a functional portion 38 .

The toilet bowl 32 is a Western-style toilet bowl. The toilet seat 34 is attached to the front side of the toilet bowl 32 and serves as a seat surface on which the user sits. A heater for heating the toilet seat 34 is provided inside the toilet seat 34 . The toilet lid 36 is a lid that covers the opening of the toilet bowl 32 , and is rotatably supported by a functional part 38 placed on the rear upper surface of the toilet bowl 32 .

The functional unit 38 includes a storage battery (not shown), and uses the power stored in the storage battery to wash the bottom of the shower toilet (registered trademark), heat the toilet seat 34, open and close the toilet seat 34, and operate the toilet lid. Various functions such as opening and closing operations of 36 are executed.

In this embodiment, the storage box 10 is attached to the inner surface 102a of the wall 102 behind the toilet room. The storage box 10 is attached at a height of about 180 cm to 200 cm from the floor 104, for example.

The storage box 10 is a rectangular box formed of face members including a top plate 10a, a bottom plate 10b, a back plate 10c, side plates 10d and a front door 10e. These face materials form a storage space 12 . The front door 10e is attached so as to be openable and closable for taking in and out stored items such as toilet paper 13 and the like. The storage box 10 is formed in such a size that a plurality of pieces of toilet paper 13 can be stored in the storage space 12 .

A storage box 10 according to this embodiment includes a power receiving unit 20 arranged in a storage space 12 . The power receiving unit 20 includes a power receiving coil 21 , a capacitor (not shown), a fixing plate 22 and a power supply cable 23 . The receiving coil 21 and the capacitor are connected in series to form a resonance circuit. A capacitor may be a stray capacitance or a circuit element. The receiving coil 21 and the capacitor are fixed to a fixing plate 22 and attached to the inner surface of the back plate 10c by the fixing plate 22 . The power receiving unit 20 is attached to the inner surface of the surface member facing the wall 102 (the back plate 10c in this embodiment) among the plurality of surface members forming the storage box 10 . For example, if the side plate 10d faces a wall in another embodiment, the power receiving unit 20 may be attached to the inner surface of the side plate 10d.

The power supply cable 23 extends from the fixing plate 22 to the outside of the storage space 12 and is connected to the storage battery of the functional unit 38 of the toilet device 30 . The power supply cable 23 transmits the power received by the power receiving unit 20 to the functional section 38 of the toilet device 30 .

A power supply device 40 is provided outside the toilet room 100 . The power supply device 40 includes a power supply unit 41 and a control unit 42 .

The control unit 42 supplies power to the power supply unit 41 based on the power supplied from the outlet through the power plug. The control unit 42 is attached to the outer surface 102 b of the wall 102 .

The power supply unit 41 includes a power supply coil 43 , a capacitor (not shown), and a fixing plate 44 . The feeding coil 43 and the capacitor are connected in series to form a resonance circuit. A capacitor may be a stray capacitance or a circuit element.

The feeding coil 43 and the capacitor are fixed to a fixing plate 44 and attached to the outer surface 102 b of the wall 102 by the fixing plate 44 . The power supply unit 41 is attached at a position facing the power reception unit 20 with the wall 102 and the back plate 10c interposed therebetween.

The power supply coil 43 wirelessly transmits the power supplied from the control unit 42 to the power reception coil 21 inside the storage box 10 via the wall 102 . Power is transmitted by magnetic field resonance between the power feeding coil 43 and the power receiving coil 21 .

According to the storage box 10 according to the present embodiment, by providing the power receiving coil 21 in the storage space 12, power can be wirelessly supplied from the power feeding coil 43 outside the toilet room 100 through the wall 102. can be done. The supplied electric power is stored in the storage battery of the functional unit 38 of the toilet device 30 via the power supply cable 23, and can be used for heating the toilet seat 34 and the like. Thus, according to the storage box 10, power can be suitably supplied to the toilet device 30 without large-scale construction such as installing an outlet on the wall 102. FIG.

In addition, in the present embodiment, by providing the power receiving coil 21 in the storage space 12 , it is possible to physically prevent human body parts from approaching the vicinity of the power receiving coil 21 . That is, since storage space 12 (for example, large enough to store a plurality of pieces of toilet paper 13 ) is provided in storage box 10 , human body parts can be physically kept away from receiving coil 21 . As a result, exposure to the human body can be reliably prevented, and safety can be improved.

The guidelines of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) stipulate a safe distance of 30 cm in a direction in which a hand does not touch or approach in normal use. Therefore, it is desirable to set the size of the storage box 10 so that the human body part cannot enter within a distance of 30 cm from the receiving coil 21 .

Further, the storage box 10 according to this embodiment includes a sensor device 50 that detects the open/closed state of the front door 10e. When the sensor device 50 detects that the front door 10 e is open, the sensor device 50 sends a signal to the control unit 42 of the power supply device 40 to stop the power supply of the power supply coil 43 . As a result, even when the front door 10e is opened and the hand is put into the storage space 12, exposure to the human body can be reliably prevented.

A shielding material made of a member that shields magnetism, such as a metal material, may be provided on a part of the plurality of surface materials that constitute the storage box 10 . In this case, human exposure can be prevented more reliably. The shielding material can be provided on all the surface members except for the back plate 10c positioned between the power receiving coil 21 and the power feeding coil 43. In particular, the front door 10e and the bottom plate 10b, which are close to the human body, can be provided with the shielding material. desirable.

When the distance between the power receiving coil and the shielding material is short, the shielding material affects the spatial impedance of the power receiving coil, which may reduce the transmission efficiency. However, in the storage box 10 according to the present embodiment, the distance between the power receiving coil 21 and the surface material is more than a certain distance due to the presence of the storage space 12, so it is possible to prevent such a decrease in transmission efficiency. can.
