Abstract
A siphon coffee maker consists of a lower container into which water is poured and which is heated with an electric heater, an upper container for containing coffee powder, the upper container communicating with the lower container so that hot water is transferred between the containers through a water feed tube due to siphon effects, and a pressure reducing valve which communicates the lower container with the atmosphere. The pressure reducing valve is opened for approximately 60 seconds for a soak-like processing when the temperature of the water reaches approximately 100.degree. C. Alternately, a pressure reducing valve is kept opened from the time when the temperature of the lower container reaches approximately 105.degree. C. to the time when the ingredients extracting operation is completed.
Claims7
A coffee maker or like beverage making device comprising:
- (a) a lower container for containing water;
- (b) a heater for applying heat to said lower container;
- (c) an upper container for containing a material such as coffee powder, said upper container having a water feed tube, said water feed tube having a portion thereof insert into said lower container;
- (d) a filter provided in said upper container for preventing transfer of the material into said lower container and allowing a beverage such as coffee to be made to transfer into said lower container through said water feed tube;
- (e) a pressure reducing valve communicating said lower container with the atmosphere when opened;
- and
- (f) a means for opening said pressure reducing valve for a predetermined period of time corresponding to a soak-like processing period of time after a predetermined short period of time from the time when hot water in said lower container starts to transfer to said upper container through said water feed tube and further closing said pressure reducing valve when the predetermined period of time elapses.
