ELECTRIC WATER HEATER

WIPO Patent Application WO/2017/125771

A8

The invention relates to a heater device (1) for heating an electrically conductive liquid, comprising a multiple-part housing having a bottom portion (3), a side wall (4), a cap portion (2) comprising a liquid inlet opening (5) and a liquid outlet opening (6), and an inlet pipe (7) connected to the liquid inlet opening (5), an alternating electrode (11) comprising multiple through-bores, the alternating electrode being arranged horizontally inside the housing, multiple receiver electrodes (12), arranged above one another inside the housing substantially parallel with the plane of the alternating electrode (11) and being spaced apart from one another and from the alternating electrode (11), and electrically insulating spacers (9) and spacer rings (8) adapted for retaining the electrodes at predetermined respective relative positions, where the electrically conductive liquid enters the inner space (10) through the inlet pipe (7) connected to the liquid inlet opening (5), and where the electrically conductive liquid flows through the through-bores and receiver electrodes (12) disposed on the alternating electrode (11) while being heated up by an alternating electric power applied between the alternating electrode (11) and one of the receiver electrodes (12). The heater device according to the invention is characterized in that each receiver electrode (12) is an electrically conductive hemispherical mesh adapted to have a favourable, effect on the flow of bubbles generated inside the liquid at the rim (15) of the through-bores (14) of the alternating electrode (11).
