Cordless kitchen appliances

Smart pan

Inductive power sources (transmitters) may be stand alone or integrated in the kitchen counter tops or dining tables.

Transmitters could combine the Wireless Power transfer to an appliance with conventional Inductive Heating.

Inductive Power Sources

Inductive Power Transfer (IPT)

Power may be transferred with induction using a

primary coil (in the transmitter) and a secondary

coil (in the appliance). This is the same as Qi.

Induction Heating (IH)

Power (heat) may be transferred directly into the

metal base of an appliance by induction heating.

This method may be cheaper and more efficient

for cordless heating appliances such as kettles

and smart pans.

Principle of Operation

1. Avoid brand lock in

– Consumers can buy whatever appliance brand they like

– Kitchen installer can choose from multiple suppliers

Why do we need a standard?

2. Consumers want interoperability

– Appliances can be moved around in the kitchen or in the house.

– Appliances still work when moved to another house

– A logo will indicate interoperability

3. Create a market for inductive power sources and components

– Consumers will profit from the economies of scale

What Benefits will it bring to consumers?
