Two electrical power components used in the course of operating an appliance are configured to operate at frequencies which are out-of-phase with respect to one another such that operating noises produced by the first component are effectively reduced in magnitude based on the operation of the second component. The components can be constituted by multiple pumps, a pump/motor combination, a motor and transformer or the like. Operational vibrations can also be reduced by mounting the components in a cabinet of the appliance through a common bracket.

1. An appliance comprising:a cabinet shell;a first electrical power component mounted within said cabinet shell, said first power component being required to perform work for operation of the appliance, with the first power component producing a first operating noise having a first frequency and a first volume level; anda second electrical power component mounted within said cabinet shell, with said second power component performing, without using a speaker or sensor, a dual function including a working function required for operation of the appliance, and a sound cancellation function by producing a second operating noise having a second frequency which is configured to be out-of-phase with the first frequency, wherein the first volume level is reduced by the second operating noise and wherein said appliance does not fully function without said second electrical power component. 2. The appliance according to claim 1, wherein the second power component is mounted directly adjacent the first power component within the cabinet shell. 3. The appliance according to claim 2, wherein the first and second power components are secured within the cabinet shell through a common attachment element. 4. The appliance according to claim 1, wherein the first power component constitutes a first pump. 5. The appliance according to claim 4, wherein the second power component constitutes a second pump. 6. The appliance according to claim 5, wherein the first and second pumps are secured to a common mounting bracket. 7. The appliance according to claim 1, wherein the second component constitutes a transformer. 8. The appliance according to claim 7, further comprising a phase altering device electrically connected to the transformer, said phase altering device being electrically interposed between a source of power and the first power component. 9. The appliance according to claim 7, wherein the first power component constitutes an electric motor. 10. The appliance according to claim 7, wherein the transformer further functions to power auxiliary electrical devices of the appliance. 11. The appliance according to claim 1, wherein the second frequency is 180° out-of-phase with the first frequency. 12. The appliance according to claim 1, wherein the appliance comprises a washing machine. 13. The appliance according to claim 1, wherein the second power component is mounted directly adjacent the first power component within the cabinet shell. 14. The appliance according to claim 13, wherein the first and second power components are secured within the cabinet shell through a common attachment element. 15. A method of operating an appliance including a cabinet shell comprising:placing a first electrical power component in an operational state thereby rotating an element within the cabinet shell of the appliance with the first power component and producing a first operating noise having a first frequency and a first volume level; andreducing the first volume level by activating a second electrical power component which produces, without using a speaker or sensor, a second operating noise having a second frequency which is out-of-phase with the first frequency. 16. The method according the claim 15, further comprising: controlling an operating phase of the second power component through a phase altering device arranged electrically in series with each of the first and second power components. 17. The method according to claim 15, wherein the second power component is operated 180° out-of-phase with the first frequency. 18. A method of operating an appliance including a cabinet shell comprising:placing a first electrical power component in an operational state thereby producing a first operating noise having a first frequency and a first volume level;reducing the first volume level by activating a second electrical power component which produces, without using a speaker or sensor, a second operating noise having a second frequency which is out-o f-phase with the first frequency; andcontrolling first and second fluid flows through the first and second power components respectively.
