Refrigerator appliance including a water filter with wireless power transfer

A refrigerator appliance comprising:

• a cabinet;
• a food storage chamber defined in the cabinet;
• a filter dock provided within the food storage chamber;
• a transmitter power coil provided at the filter dock;
• and
• a water filter removably coupled to the filter dock, the water filter comprising:
• a body comprising an outer shell, the outer shell forming a liquid receiving space therewithin and defining an electronics compartment fluidly separated from the liquid receiving space, the body comprising an inlet opening through the body into the liquid receiving space and an outlet from the liquid receiving space, wherein a portion of the outer shell is positioned between the liquid receiving space and the electronics compartment;
• a filter material positioned entirely within the liquid receiving space to filter water therethrough;
• a first antenna attached to the body and positioned entirely within the electronics compartment, the first antenna facilitating a wireless communication between the refrigerator appliance and the water filter;
• a power harvesting circuit attached to the body and positioned entirely within the electronics compartment, the power harvesting circuit being operably connected with the first antenna;
• and
• one or more electronic components positioned entirely within the electronics compartment, the one or more electronic components operably coupled to the power harvesting circuit, wherein the first antenna wirelessly receives a first electromagnetic field from the transmitter power coil to provide power to the one or more electronic components via the power harvesting circuit.
