AI Technical Summary
⚠Technical Problem
Existing coffee machines with integrated grinding devices generate significant noise due to vibrations, which are not effectively decoupled from surrounding components, leading to noise propagation and discomfort for users.
⚗Method used
Incorporation of a decoupling gasket made of soft material with a Shore A hardness of 35 or less, shaped as an inverted 'C' with a through hole, positioned between the hopper and grinding device, to absorb kinetic energy and reduce noise transmission.
🎯Benefits of technology
Effectively decouples the grinding device from the hopper, reducing overall noise levels and allowing the use of lightweight hoppers, while maintaining efficient grinding performance.
