WIRELESS ELECTRICAL APPLIANCE Russian patent published in 2014 - IPC A47J27/21 

FIELD: personal use articles.

SUBSTANCE: invention relates to cordless (wireless) electrical household appliances including but not limited to wireless liquid heating vessels. The wireless electrical household appliance contains the electric appliance proper having at least two functional components (T1, M1) and a stand for the electrical appliance power supply. The electrical connection between the electrical appliance proper and the stand in the process of the electrical appliance functioning is ensured by a cordless electrical connector (6). The both functional components are placed between the electrical connection points pair in place in the connector. Power supply to at least one of the functional components (T1, M1) is selectively ensured as a result of change of relative polarities of the said electrical connection points. Placed between the functional components (T1, M1) may be a switch such as a diode (D1) for carrying out or interrupting supply of current to the functional component (T1, M1) depending on relative polarities of the said connection points.

EFFECT: invention ensures shared usage of a common pair of electrical connection points (terminals) in place in the connector by two components of the electrical appliance while the controlling means such as an electronic controlling circuit is designed so that to enable switching of the two electrical terminals relative polarities with the electrical device functional performance to be improved, as a result, without introduction of additional terminals.
