Abstract

See full text

In an electrical continuous flow heater for an appliance such as a coffee machine, a tubular heater member has a jacket tube in heat conducting contact with a pipe for carrying the fluid to be heated, with the pipe and jacket tube disposed in horizontal side-by-side relationship. The jacket tube or the pipe, or both, have a wall thickness which varies over the periphery thereof, the thickest portion of the pipe wall being lowest in the horizontal position during use and the thickest portion of the jacket tube contacting the pipe. In one arrangement, the thickest portion of the tubular jacket and/or pipe is provided by a strip of sheet metal attached to such pipe or tubular jacket. In another arrangement, the pipe and jacket tube are constructed as a unitary extruded member.
