Patent Searching and Data


Title:
KETTLE KNOB APPARATUS GENERATING SOUND SIGNAL
Document Type and Number:
Japanese Patent JPS57175325
Kind Code:
A
Abstract:
A knob for a cooking vessel is a whistle which gives an audible signal that cooking temperature has been reached, and has a valve slide assembly including a separate leaf spring for shutting off the whistle. Supporting inside and outside knob parts incorporate halves of a resonance chamber, which makes the knob extremely simple to mold, assemble, clean, and disassemble. The valve slide rests in guides which make it impossible to assemble incorrectly, and is overlaid by a knob cover. The leaf spring biases the valve slide against the top wall of the resonance chamber so that when the slide valve is closed the passage from the resonance chamber to the ambient air is effectively blocked.
