    • The invention relates to a coffee machine, especially an espresso or coffee pad machine, comprising an electric instantaneous water heater (22) for heating water transported by means of a pump (68) via a delivery line (80) from a storage tank (20), said water being guided under pressure, after being heated, into a brewing chamber (24), for the preparation of the coffee. A safety valve (72) is provided outside the instantaneous water heater (22), for automatically reducing excess pressure. The aim of the invention is to improve one such coffee machine in such a way that the excess pressure in the system can be silently reduced without damaging the materials. To this end, the safety valve (72) is arranged upstream of the inlet of the instantaneous water heater (22). The inventive embodiment enables cold water, instead of aggressive water vapour, to be guided away via the safety valve, reducing the noise and causing less damage to the materials.
    • 本发明通过经由从储罐的进料管线(80)的泵(68)的装置涉及一种咖啡机,特别是浓咖啡或咖啡垫机,具有一个电加热器(22),用于加热(20)产生的水,其,加热咖啡后 被引导到泡制室的压力(24)下,在连续流加热器(22)的外部是用于自动地减少过多的压力,提供了安全阀(72)。 为了开发一种通用咖啡机,使得在可能的,它提出了一种低噪声,并在系统过压的节省材料的减少,该流加热器(22)的入口之前的安全阀(72)被布置。 本发明的设计,采取积极蒸气冷水通过安全阀,其可以静静地进行,并且材料的相容性实现放电。
