Abstract

A device and a method for reducing or muffling sound from kitchen appliances such as coffee grinders. The sound reducing or muffling device can be left on the appliance even when not in use, providing a decoration to the kitchen in a style appropriate to it'"'"'s surroundings. Using the muffling device, a person can enjoy fresh-ground coffee at any time with the assurance that the sound from the coffee grinder is well insulated. The device is particularly easy to deploy and use, requires no moving parts, and is flexible enough to work with the majority of coffee grinder products currently on the market. Other embodiments can be used with other forms of kitchen appliances.

Claims

1. An apparatus for reducing the sound of a kitchen appliance, said apparatus comprising:

a housing having a substantially cylindrical shape, said housing including a curved sidewall defining an open bottom of said housing configured to receive the kitchen appliance, said curved sidewall further defining a closed peripheral top end of said housing, wherein said housing includes a sound reducing material;

a laminar insert stiffening element located within said peripheral top end, wherein said stiffening element is a laminar plastic insert; and

,

wherein pressure can be applied to said stiffening element to activate said kitchen appliance.

2. The apparatus of claim 1 wherein said sound reducing material is an acoustic foam.

3. The apparatus of claim 2 wherein said acoustic foam is bonded to said housing.

4. The apparatus of claim 1 wherein said housing is fabricated from a material that flexibly adapts to the contours of said kitchen appliance.

5. The apparatus of claim 1 wherein said kitchen appliance is a coffee grinder.

6. An apparatus for operating a coffee grinder while at the same time reducing the sound from said operating;

comprising;

a housing having a substantially cylindrical shape, and fabricated from a material that flexibly adapts to the contours of said coffee grinder, said housing including a curved sidewall defining an open bottom of said housing for receiving said coffee grinder, said sidewall further defining a peripheral top end of said housing enclosure;

a sound reducing material within said housing;

a switch engaging mechanism including a laminar insert located within said peripheral top end, which when said coffee grinder is received within said housing, said switch engaging mechanism is in mechanical communication with an operation switch of said coffee grinder, wherein said laminar insert is made of a stiffened plastic.

7. The apparatus of claim 6 wherein said switch engaging mechanism can be used to operate said coffee grinder from outside of the housing.

8. The apparatus of claim 6 wherein said sound reducing material is an acoustic foam.

9. The apparatus of claim 8 wherein said acoustic foam is bonded to said housing.

10. The apparatus of claim 6 wherein said housing is fabricated from a material that flexibly adapts to the contours of said coffee grinder.
