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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
