  • Patent number: 11707152
    Abstract: The present disclosure provides a float valve motion detection device, a pot cover assembly and a pressure cooking appliance, the float valve motion detection device comprising: a float valve, a hollow inductance coil and a detection circuit. A valve core of the float valve is made of materials having permeability unequal to that of air. When the valve core is pushed by the pressure in a pot from a first position to a second position, the volume of the valve core in the hollow inductance coil changes, which changes the inductance of the hollow inductance coil. A detection circuit determines the position of the valve core by means of detecting the change in the inductance of the hollow inductance coil so as to determine whether it is safe to uncover at the current time.

  • Patent number: 11607751
    Abstract: A laminate sheet including a weldable margin is formed by laminating metal sheets having a core layer disposed therebetween. The core layer is formed of a core material which includes one or more of a viscoelastic, adhesive and acoustic material. The core layer is selectively distributed such that the laminate sheet includes an adhered region providing a laminate structure, and a non-adhered region including a weldable margin. The non-adhered region is adjacent an edge of the core layer and is characterized by a gap between the first and second metal sheets and by an absence of the core layer in the gap. The non-adhered region defines a weldable margin adjacent a core edge configured such that a weld is formable in the weldable margin without heat affecting the core layer. The laminate sheet can be joined by fasteners installed in the non-adhered region.
