Patent ID: 7966927

Claim:
A standalone drink dispensing machine for delivering a drink by extraction under pressure from a capsule comprising: an extraction module which is intended to receive a capsule and which comprises means of injecting water under pressure into the capsule and means of receiving the capsule, a water reservoir for supplying the said module with water; the said reservoir being of sufficient capacity for successively supplying the said module for extraction from several capsules, a pump for drawing water from the reservoir and supplying the capsule with water under pressure from the water injecting means of the extraction module, electrical power supply means for normally providing electrical power for heating the water in the reservoir up to a reserve temperature higher than or equal to the extraction temperature, and for supplying the pump electrically, and a low voltage electrical accumulator is configured to supply electrical current for heating the water in the reservoir when the electric power supply means is disconnected, wherein the reservoir comprises heating means, wherein the heating means comprises a first electrical element powered by the accumulator, and a second electrical element, independent of the first element, that is capable of initially being powered by current from the electrical power supply means and configured to be supplied with electrical power from the electrical power supply means in order to normally heat the water up to the reserve temperature, and the first electrical element is to be supplied with electrical power from the electrical accumulator when the electric power supply means is disconnected in order to compensate for the heat losses after heating up the water to the reserve temperature.
