Abstract

A blender system is provided that includes a motorized base and a mixing assembly attached thereto in which materials to be blended may be contained and blended. The motorized base includes several mechanisms for reducing noise emitted by the motor that powers the blender blades. The mechanisms may include elastic isolators in communication with components within the blender system, stiff plates positioned to absorb vibrations and noise emitted by the motor, and a sound cover that can be placed around the mixing assembly.

First claim

What is claimed is:

1 . A sound-reducing system for reducing noise emitted by a motor in a blender, the sound-reducing system including:
a top stiff plate; one or more top isolators coupled to the top stiff plate to form a first self-supporting structure; a bottom stiff plate; and one or more top isolators coupled to the bottom stiff plate to form a second self-supporting structure.

2 . The sound-reducing system of claim 1 wherein the sound-reducing system is located within a base of the blender.

3 . The sound reducing system of claim 2 wherein the base is coupled to a blending container in which contents to be blended are contained.

4 . The sound reducing system of claim 1 further comprising foam abutting at least one of the top stiff plate, the one or more top isolators, the bottom stiff plate, and the one or more bottom isolators.

5 . The sound reducing system of claim 3 further comprising a sound cover surrounding the blending container.

6 . A blender system, the blender system comprising:
a motorized base including a motor within the motorized base; at least one stiff plate located within the motorized base; and at least one elastic isolator coupled to the stiff plate.

7 . The blender system of claim 6 further including a mixing assembly coupled to the motorized base in which contents to be blended may be contained.

8 . The blender system of claim 7 , wherein the blender system includes a blending container and a sound cover surrounding the blending container.

9 . The blender system of claim 6 , wherein the blender system includes each of an upper stiff plate and a lower stiff plate, and wherein the at least one elastic isolator is coupled at a first end to the upper stiff plate and at a second end to the lower stiff plate.

10 . The blender system of claim 6 , wherein the motorized base further includes acoustic foam adjacent to the motor.

11 . The blender system of claim 6 , wherein the motorized base includes a fan decoupled from the motor for cooling the motor.

12 . The blender system of claim 7 further comprising a sealing sub-assembly positioned and located between the motorized base and the mixing assembly such that the sealing sub-assembly physically abuts each of the motorized base and the mixing assembly.

13 . The blender system of claim 6 , wherein the blender system includes a housing surrounding the motor to further reduce noise emitted by the motor.

14 . The blender system of claim 6 further comprising a shroud surrounding the motor that includes a tortuous internal path.

15 . A blender system, the blender system comprising:
a motorized base including a motor within the motorized base; and at least one isolator within the motorized base coupled to one or more components within the motorized base, the at least one isolator being elastic for reducing transmission of vibrations within the motorized base.

16 . The blender system of claim 15 , the motorized base further including at least one stiff plate contained therein for reducing transmission of vibrations within the motorized base.

17 . The blender system of claim 15 further including a mixing assembly coupled to the motorized base in which contents to be blended may be contained.

18 . The blender system of claim 17 , wherein the blender system includes a blending container that can be coupled to the motorized base.

19 . The blender system of claim 18 , wherein the blender system includes a sound cover surrounding the blending container.

20 . The blender system of claim 17 further comprising a sealing sub-assembly positioned adjacent to and abutting the motorized base for providing a gap between the motorized base and the blending container.
