The technical scheme of the invention is as follows: a
water heating machine comprises a housing, a panel, a base plate, a water receiving tray, a water tank, an outer water tank receptacle, a water pump, a heater
assembly, a steam
discharge pipe, a water outlet hood, a water tank cover, a pipeline, a
pilot circuit and a
water temperature control system; as seen in the figure, the heater
assembly consists of an
electric heating tube, a stainless
steel tube, a
silicon rubber
flange, a water inlet chamber, a water outlet chamber, a communicating tube, a
water level control tube, a magnetic floating ball, a dry reed
pipe and an upper cover; a water inlet, a water outlet, a water return
pipe and a floating ball chamber are arranged at the bottom of the water inlet chamber; the
water temperature control system comprises a
water temperature control button, a pull line, the
water level control tube, a seal ring, a tension spring and a microswitch; the
water level control tube is arranged in the water return pipe of the water inlet chamber and can slide up and down in the water return pipe; the seal ring is arranged between the lower end of the water level control tube and the water return pipe; and the outer water tank receptacle consists of a housing, a
silicone rubber seat, an inner valve and a spring. The
water heating machine provided by the invention can provide boiling water within 3-5 seconds; has the advantages of simple structure, high stability and reliability, safety,
hygiene, convenience for operation and zero idle
power consumption; and is significant in market advantages.
