Abstract (en)
[origin: DE19508315C1] A heating unit for water bed, consists of electrical resistance conductors which are located between a bed frame and a safety film, and a temp. control. The unit comprises ceramic plates (13-18) with electrical conductors (23), which are glued to the bottom (11a) of a stiff metal plate (11) using an adhesive (19) with a high thermal conductivity. The plate is applied to a base-plate (12) of poor thermal conductivity, while leaving an air gap (33) for the ceramic plates. The base-plate pref. consists of a plastic, e.g. acryl nitrile-butadiene styrol copolymers, polyurethane, polyamide or a polyethylene.
