Dish washing machine using induction heating

1 . A method of washing dishes comprising:

providing a housing having an interior wash space for receiving dishes;

adding initial water, which is fresh water, to a dish washing machine;

feeding the initial water to a fresh water reservoir;

heating the initial water in the fresh water reservoir to form initially heated initial water;

delivering the initially heated initial water to a first water tank;

heating the initially heated initial water in the first water tank with a first heating system to form secondarily heated initial water;

supplying the secondarily heated initial water to at least one spray nozzle;

spraying the secondarily heated initial water onto the dishes received within the interior wash space;

delivering the secondarily heated initial water from the interior wash space to a second water tank;

heating the secondarily heated initial water in the second water tank with a second heating system to form heated wash water;

delivering the heated wash water to the at least one spray nozzle;

spraying the heated wash water into the interior wash space; and

draining the heated wash water through a drain pipe that passes through the fresh water reservoir and to a liquid outlet;

wherein at least one of the first heating system and the second heating system heats water through induction.

2 . The method of claim 1 , further including:

pumping the secondarily heated initial water from the first water tank to the at least one spray nozzle with a pump.

3 . The method of claim 1 , wherein:

the at least one spray nozzle is a plurality of spray nozzles located on a top rotating arm and a bottom rotating arm.

4 . The method of claim 1 , wherein:

the drain pipe includes a horizontal portion within the fresh water reservoir and an elbow hot water waste retainer just outside of the fresh water reservoir, the elbow hot water waste retainer including a lower surface that is above the horizontal portion to allow the heated wash water to pool in the horizontal portion.

5 . The method of claim 1 , further including:

pumping the secondarily heated initial water from the first water tank to the at least one spray nozzle with a first pump; and

pumping the heated wash water from the second water tank to the at least one spray nozzle with a second pump.

6 . The method of claim 1 , wherein:

a heat insulating cylinder surrounding the first water tank and induction coils coiled around the heat insulating cylinder, the coils receiving a current therethrough to heat the initially heated initial water in the first water tank.

7 . The method of claim 1 , wherein: the first heating system comprises a base having induction coils therein in a pancake shape and a rectangular heat insulating sleeve surrounding the first water tank, with the first water tank being positioned on top of the base, and with the coils receiving a current therethrough to heat the initially heated initial water in the first water tank.

8 . A method of washing dishes comprising:

providing a housing having an interior wash space for receiving dishes;

adding initial water to a dish washing machine;

delivering the initial water to a first water tank;

heating the initial water in the first water tank with a first heating system to form heated initial water;

supplying the heated initial water to at least one spray nozzle;

spraying the heated initial water onto the dishes positioned within the interior wash space;

delivering the heated initial water from the interior wash space to a second water tank;

heating the heated initial water in the second water tank with a second heating system to form heated wash water;

delivering the heated wash water to the at least one spray nozzle; and

spraying the heated wash water into the interior wash space;

wherein at least one of the first heating system and the second heating system heats water through induction; and

wherein at least one of the first heating system and the second heating system comprise a stainless steel shell with a positive temperature coefficient heating array located therein, the positive temperature coefficient heating array comprising a plurality of positive temperature coefficient heating elements, with a temperature sensor being connected to a heater cover; and the method further comprises measuring, a temperature of the first heating system with the temperature sensor to maintain the temperature of the first heating system under a predetermined temperature.
