Abstract
A domestic carbonation appliance has a replaceable CO2 cylinder and accepts a refillable bottle with a removeable cap. The cap can cooperate with a carbonation head of a domestic carbonation device but lacks bayonette or thread features for engaging the carbonation head. The device provides for “one-touch” carbonation.
Claims18
A device for carbonating a liquid, the device comprising:
- a carbonation head, pressure transducer and processor module;
- wherein the carbonation head is connectable to a bottle whose liquid contents are to be carbonated and has a first through passageway that, when connected, distributes pressurised carbon dioxide to an interior of the bottle;
- and a second passageway that communicates a pressure within the bottle to the pressure transducer;
- and
- the processor module is coupled to the pressure transducer to receive a signal indicative of the pressure within the bottle;
- wherein
- the processor module, prior to commencing carbonation, causes delivery of a single short predetermined pulse of a gas into the bottle, and the pressure transducer subsequently measures a resultant pressure within the bottle;
- the processor module being further adapted to monitor the resultant pressure within the bottle and to compare the measured pressure to a predetermined safe pressure range defined by a lower first pressure value and a upper second pressure value for confirming a safe volume of liquid in the bottle;
- such that, if the measured pressure is within the safe pressure range, the processor can cause the device to commence carbonation of the liquid.
