System and method for electrical protection of appliances

An electrical protection system for a household electric appliance, the system comprising:

• an electric system at least partially housed in a housing of the electric appliance, said electric system including an electrical power unit and an electric work unit, wherein the electrical power unit is configured for detachable connection to an external household source for receiving external electrical power from the external household source, said electrical power unit being further configured to convert the external electrical power to internal electrical power for receipt and use by the electric work unit, and said external electrical power having a first power waveform of about 110-240 volts AC at 50-60 Hz, and wherein the electric work unit is configured to utilize the internal electrical power received from the electrical power unit for carrying out one or more designated work functions of the appliance, and wherein the electric system operates according to a second power waveform;
• and
• an electrical protection unit permanently interfaced with the electric system, wherein the electrical protection unit is configured to allow the external electrical power to pass to the electric system from the household source if the second power waveform is within a waveform profile, and to substantially prevent the external electrical power from passing to the electric system from the household source if the second power waveform is outside a fault deviation of the waveform profile, said waveform profile being indicative of normal electrical operation of the household electric appliance;
• wherein the electrical protection unit comprises one of an AFCI unit, a GFCI unit, or a combination GFCI/AFCI unit;
• and
• wherein the electric system and electrical protection unit together comprise a totality of the electrical circuitry in the household electric appliance.

A method for electrically protecting a household electronic device, the method comprising:

• generating an electrical waveform profile of the household electronic device during operation of the household electronic device under designated normal conditions;
• selecting an electrical protection unit based on said waveform profile, wherein the electrical protection unit is selected to allow electrical power to pass to the household electronic device from an external household source if an operational electric power waveform of the household electronic device falls within the waveform profile, and wherein the electrical protection unit is selected to substantially prevent electrical power from passing to the household electronic device from the external household source if the operational electric power waveform of the household electronic device falls outside a fault deviation of the waveform profile;
• and
• permanently integrating the electrical protection unit with the household electronic device, prior to distribution of the household electronic device to a household end user, so that the electrical protection unit cannot be removed from household electronic device by the household end user without disabling the electronic device.
