The wireless power supply kitchen system provides a novel power supply mode for kitchen appliances, which effectively improves the convenience and convenience of the use of kitchen appliances. safety. This type of kitchen appliance can be directly placed on the kitchen countertop or dining table inlaid with the wireless power transmitter to obtain electric energy without the need for To obtain power through the power cord. The electrical energy of these new kitchen appliances comes from non-contact electromagnetic inductive power transmission, that is, in the transmitter. The inductive coil of the electric appliance obtains energy from the main power supply, and transmits it to the coil located at a certain interval and located inside the kitchen appliance through the principle of electromagnetic induction. Then It is then converted into electrical energy or heat energy for cooking food. Wireless Powered Kitchen System Design Guidelines

1 Scope

GB/Z 41528-2022 is the Chinese national standard on design guidelines of wireless power supplying kitchen system, in the field of domestic and commercial equipment, entertainment, sport. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 11 July 2022 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 97.040, CCS V85. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
