  • Publication number: 20230131914
    Abstract: The present invention relates to the field of food processing technology, and more particularly to an air fryer with multiple frying baskets. The air fryer includes a housing provided with a cooking chamber, multiple heating members provided in the housing to heat the cooking chamber, a frying assembly, and multiple control systems provided in the housing. The frying assembly includes a first basket, multiple second baskets, and multiple front cover assemblies detachably connected to the first basket or the second baskets. The numbers of the second baskets, the front cover assemblies, the heating members, and the control systems are all the same. The second baskets are placed inside the first basket all at once. The cooking chamber is adapted to accommodate the first basket or to receive all of the second baskets. Each of the control systems is electrically connected to one of the heating members.

  • Publication number: 20190296458
    Abstract: The invention discloses a grounding elastic component, including a elastic body and a conductive thin film. A convex block is provided on a lower surface of the elastic body, which convex block divides the lower surface of the elastic body into a first region and a second region. A conductive metal layer is provided on one side of the conductive thin film, and the other side of the conductive thin film, which is opposite to the one side the conductive metal layer is provided on, is wrapped on an upper surface, the first region of the lower surface and a side wall of the elastic body. The conductive thin film is bonded with the upper surface and the first region of the lower surface of the elastic body by a non-conductive double-sided adhesive. A double-sided adhesive tape is provided on the second region of the lower surface of the elastic body.
