Wireless energy transfer for refrigerator application
View Patent ↗Described herein are improved configurations for a refrigerator with wireless power transfer that includes an enclosure member comprising a non-metallic material, a source comprising at least one high-Q source magnetic resonator coupled to a power source and generating an oscillating magnetic field, wherein the source is integrated into the enclosure member of the refrigerator.
1. A refrigerator with wireless power transfer comprising:
an enclosure member comprising a non-lossy magnetic material; and
a source comprising at least one high-Q source magnetic resonator coupled to a power source and generating an oscillating magnetic field,
wherein the source is integrated into the enclosure member of the refrigerator and oriented to allow a device that is attached to the enclosure member with a permanent magnet to capture energy from the oscillating magnetic field at a plurality of locations on the enclosure member, and
wherein the permanent magnet is capable of attaching to the refrigerator via magnetic attraction of the permanent magnet to the non-lossy magnetic material of the enclosure member.
2. The refrigerator of claim 1 , wherein at least one said high-Q source magnetic resonator is configured to generate said oscillating magnetic field that is partially inside the refrigerator.
3. The refrigerator of claim 1 , wherein at least one said high-Q source magnetic resonator is configured to generate said oscillating magnetic field that is partially outside the refrigerator.
4. The refrigerator of claim 3 , wherein said enclosure member is part of a door of the refrigerator.
5. The refrigerator of claim 3 , wherein said enclosure member is part of a side of the refrigerator.
6. The refrigerator of claim 1 , wherein at least one source magnetic resonator is a planar resonator comprising an electrical conductor wrapped around a block of magnetic material.
7. The refrigerator of claim 1 , wherein the at least one high Q source magnetic resonator is a capacitively loaded conducting loop.
8. A refrigerator wireless power transfer system comprising:
an enclosure member comprising a non-lossy material; and
a source having at least one high-Q source magnetic resonator having an electrical conductor wrapped around a block of magnetic material, the high-Q source magnetic resonator coupled to a power source and generating an oscillating magnetic field,
wherein the source is integrated into the enclosure member of the refrigerator,
wherein the oscillating magnetic field is capable of providing power at a plurality of locations on the enclosure member to a device attached to the enclosure member with a permanent magnet and having a high-Q device magnetic resonator, and
wherein the permanent magnet is capable of attaching to the refrigerator via magnetic attraction of the permanent magnet to the magnetic material of the source resonator.
9. The system of claim 8 , wherein at least one device is a sensor inside the refrigerator.
10. The system of claim 8 , wherein at least one device is a mobile handset on the outside of the refrigerator.
11. The system of claim 8 , wherein at least one device comprises a display on the outside of the refrigerator.
12. The system of claim 11 , wherein the display is a digital picture frame.
