The coffee machine for different coffee types requires no preheating time and consumes no energy in the standby mode. It essentially comprises a water supply chamber (1), a pump (5), a continuous flow heater (8) for heating the water and a brewing chamber (10) for receiving the coffee (10'). The continuous flow heater (8) has a low heat capacity and can therefore perform large temperature changes within a short time. In order to obtain the desired water starting temperature, use is made of a control loop. The unheated parts (9-12) along the water path be...
[ What is claimed is:] [1.] A coffee machine having a water supply chamber, a pump and a brewing chamber for receiving coffee comprising:a continuous flow heater for heating water comprising an inner tube for allowing water to flow therethrough, at least one inner insulating layer placed around the inner tube, and a filament wound around the at least one inner insulating layer, said continuous flow heater having a low heat capacity;at least one temperature sensor disposed at the end of the continuous flow heater or between the latter and the brewing cham...
