Abstract:
1. A water boiling device comprising, in combination: a machine body; a heat tank unit received in the machine body and including first and second heating tanks spaced in a horizontal direction, with the first heating tank in communication with the second heating tank and adapted for containing water from a water inlet pipe with water to be heated supplied to the first and second heating tanks through the water inlet pipe; a high frequency induction heater including a high frequency power and first and second induction coils, with the first and second induction coils respectively disposed around the first and second heating tanks, with the first and second induction coils electrically connected to the high frequency power with the first and second heating tanks heating up to heat the water in the first and second heating tanks when a high frequency current supplied by the high frequency power is passed through the first and second induction coils; and a heat pipe unit including first and second heating pipes, with each of the first and second heating pipes including upper and lower sections spaced in a vertical direction perpendicular to the horizontal direction, with the high frequency induction heater further including a heat pipe induction coil electrically connected to the high frequency power, with the upper section of each of the first and second heating pipes received in one of the first and second heating tanks, with the lower section of each of the first and second heating pipes located out of the first and second heating tanks and received in the heat pipe induction coil, and with the first and second heating pipes heating up to heat the water in the first and second heating tanks when the high frequency current is passed through the heat pipe induction coil.
