HYBRID APPARATUS FOR PREPARING BEVERAGES

摘要

A device for preparing hot beverages is provided and includes an arrangement for circulating a liquid to a beverage supply exit; and a combustion heating means, such as a burner, for supplying combustion heat to the liquid that is circulated to the supply exit. The combustion heating means can be associated: with an electric heating means for supplying electric heat to the liquid that is circulated to the supply exit and/or with a means for regulating the heat supplied to the liquid from the combustion heating means. The present disclosure further provides a device for heating a liquid comprising combustion heating means and a cathalic device for inhibiting flame formation.

1. A device for preparing hot beverages, the device comprising:
an arrangement for circulating a liquid from a liquid supply to a beverage supply exit; and a combustion heating means for supplying combustion heat to the liquid that is circulated to the supply exit, the combustion heating means being associated with an electric heating means for supplying electric heat to the liquid that is circulated to the supply exit, at least one of the combustion heating means and the electric heating means being associated with a means for regulating the heat supplied to the liquid from the at least one of the combustion heating means and the electric heating means, the regulating means comprising a temperature sensor that is arranged to measure directly or indirectly the temperature of the heated liquid for comparing the measured temperature with a target temperature, the temperature sensor being associated with one of: (i) the electric heating means for adjusting the supply of the electric heat based on the difference between the measured temperature and the target temperature, the combustion heating means being arranged to supply an amount of combustion heat to the liquid which is below the heat required for the liquid to reach the target temperature; or (ii) the combustion heating means for supply of the combustion heat based on the difference between the measured temperature and the target temperature, the electric heating means being arranged to supply electric heat to the liquid which is below the heat required for the liquid to reach the target temperature.
