Abstract
An instant hot water apparatus utilizing electro-magnetic induction heating. The apparatus includes a container having an outlet. A solenoid valve is connected to the outlet of the container. The first end of a water conduit with a first end and a second end is connected to the solenoid valve. An electro-magnetic induction heating coil surrounds the water conduit between its ends and is capable of producing an alternating magnetic field. A water outlet valve is connected to the second end of the water conduit. A water temperature detecting device disposed on the water conduit can generate a water temperature signal. A water level detecting device is disposed on the container and can generate a water level signal. A power control device supplies electric power. A supervising and controlling device is connected to the power control device and to the solenoid valve and is capable of transmitting an adjustable oscillation frequency. The water temperature and level signals are sent to the supervising and controlling device. The signal input is connected to the supervising and controlling device for receiving the oscillation frequency. A microswitch is connected to the water outlet. When the water outlet valve is activated, the microswitch transmits a signal to the power control device to supply electric current to the supervising and controlling device.
