Abstract: A method and apparatus for venting a liquid supply of a beverage machine, e.g., by permanently open orifice and/or pressure relief valve. The orifice may always vent a heater tank, even while liquid is delivered to the tank by a liquid pump and/or while the tank is pressurized by an air pump to deliver liquid from the tank. A filter may be positioned between a heater tank and orifice and/or air pump. The pressure relief valve may be positioned between the liquid pump and the inlet side of the heater tank, e.g., so relatively cool water is released by the pressure relief valve when open.

Abstract: Aspects relating to a method and apparatus for venting a heater tank of a beverage forming apparatus using a vent valve that is opened and closed based on an operation to move a brew chamber lid between an open lid position and a closed lid position are provided. In one aspect, the vent valve may be positioned on a vent line distinct from a delivery line that delivers heated liquid from the heater tank to the brew chamber. In another aspect, at least a portion of the delivery line may extend downwardly from the top of the heater tank to a location between the top and the bottom of the heater tank. In another aspect, the at least a portion of the vent valve may be attached to the handle for movement with the handle.

Abstract: A device and method for injecting ions into a stream of air. The device comprises a housing; an electric circuit inside the housing; an electrically conductive element coupled to the electric circuit for emitting ions, at least a portion of the conductive element being exposable to at least a portion, of the stream of air for injecting the ions into the stream of air; and a heater element disposed inside the housing for heating one or more circuit elements of the electric circuit.
