초록 ▼

A very compact tankless water heater delivers heat in proportion to demand. A flow responsive valve energizing an electrical control system is purely flow responsive, even to minute flow, and consumes no power when dormant. An uncomplicated electronic control system is connected to power by the flow switch, and is substantially deenergized when dormant. Most electronic components of the control system are mounted on the flat front wall of the pressure vessel. Thus, overall dimensions are minimized, cool water serves as a heat sink, and heat generated by electronic controls is captured for heating purposes. In particular, triacs controlling the heating elements are cooled, thus prolonging their life. A preferred embodiment of the novel heater has a maximum electrical consumption of 22 kilowatts, with equivalent heat output, and has overall external dimensions of 24 inches in height, 5.5 inches in width, and 4 inches in depth (61 cm in height, 14 cm in width, and 10 cm in depth). An outlet pipe fitting extending above adds approximately 2 inches (5 cm) to the overall height, enabling the water heater to be installed in a typical building interior wall or partition.

대표청구항 ▼

An electrically operated tankless water heater for connection to AC electric power, said tankless water heater comprising: a pressure vessel having a flat front wall for receiving, heating, and discharging water to be heated, an inlet conduit conducting unheated water into said pressure vessel, and an outlet conduit discharging heated water from said pressure vessel; a plurality of electric heating elements axially disposed within said pressure vessel; a flow switch attached to said inlet conduit exteriorly of said pressure vessel, said flow switch having a plunger displaced by water flowing into said tankless water heater, and means completing an electrical circuit to a control system, thereby providing power to and activating the control system; and a control system responsive to power being supplied thereto through said flow switch, said control system including: a source of DC power for supplying control power, first and second voltage divider circuits each connected to said DC power source and to a ground, a thermally responsive variable resistor connected in series in said first voltage divider circuit and disposed to monitor and respond to temperature within said pressure vessel, and at least one power switching subcircuit comprising a comparator for monitoring said two voltage divider circuits and controlling a driver in response thereto, said driver responding to said comparator and driving an optotriac, said optotriac driven by said driver for controlling a power triac, and said power triac controlled by said optotriac for switching AC electric power to said plurality of electric heating elements.
