摘要

One embodiment provides a non-contact power transmitter device including a sealed housing provided at least partially within a surface, and a transmitter coil within the sealed housing configured to inductively transfer power to a power receiver device. The power transmitter device also includes a transmitter control unit coupled to the transmitter coil, a transceiver configured to communicate with the power receiver device, and an electronic processor coupled to the transmitter control unit and the transceiver. The electronic processor is configured to establish, using the transceiver, communication with the power receiver device, and negotiate power transfer requirements between the power transmitter device and the power receiver device. The electronic processor is also configured to control the transmitter coil unit to transfer power to the power receiver device.

說明書

Many electrical devices are now used in harsh environments, for example, restaurant kitchens, stadiums, conventions centers, outdoor arenas, golf courses, and the like. These harsh environments originally used gas powered devices that are usually loud and inefficient and produce emissions. These gas powered devices are being replaced by wired electrical devices that are powered from electrical power inputs, for example, power grid, DC grid, digital electricity, and the like. However, wired electrical devices pose their own issues when used in harsh environments where daily cleaning or sanitation is performed. For example, having bare power outlets and power cords may produce a risk of shock to persons in the presence of cleaning solutions. Additionally, the power cords may be a tripping hazard for employees and customers.

The non-contact separable wiring device power transfer system 300 is portable and improves user-accessibility. Additionally, the non-contact separable wiring device power transfer system 300 is provided in sealed and waterproof housings so that the non-contact separable wiring device power transfer system 300 can be used in harsh environments. Specifically, the power transmitter device 310 includes a hermetically sealed housing and may be provided behind walls, in the flooring, in the ground, and the like. In some embodiments, the power transmitter device 310 may be provided on the walls, on the flooring, on the ground, and the like. For example, the sealed housing of the power transmitter device is partially or completely provided within a surface. Similarly, the power receiver device 315 also includes a hermetically sealed housing and may form part of an electrical device or an electrical appliance, for example, a fryer, an electric stove, lights, and the like.
