Abstract
A baffle for a food waste disposer to reduce noise is disclosed. The baffle has a diaphragm that allows solid and liquid waste to pass through the diaphragm, and accordingly does not substantially affect the normal operation of the disposer. However, because the baffle covers the central opening in the conventional mounting gasket of the prior art, a direct path from the grinding mechanism in the disposer to the sink is blocked, thus muffling the noise coming from the grinding mechanism. Additionally, the disclosed baffles are preferably, but not necessarily, designed so as to create a water dam on their surface by impeding the flow of water from the sink faucet in a way to create a pool of water. The disclosed baffles may be installed in the drain opening of a sink above the conventional mounting gasket, although other embodiments are also disclosed.
