ABSTRACT:
This invention concerns about an automatic coffee boiler, especially one that can feed automatically a certain amount of coffee powder and boil the coffee powder with a certain quantity of water vapor previously fixed. Its main characteristics is to use two time adjusters in a controlled circuit to respectively set a period of time for activating a coffee feeding device and an electric heater in water tank, and also to use a sequence controlling circuit which can automatically activate in sequence the coffee powder feeder, the heater in the water tank and a music alarm. Through the above-mentioned devices, coffee powder can be automatically fed out and boiled with vapor to become liquid coffee ready for drinking.
One of the other specialities of this invention is that an electromagnetic valve set at the outlet of the coffee feeding device is able to act simultaneously with said coffee feeding device. As said feeding device starts acting, said electromagnetic valve immediately pulls a vertical lid off the powder outlet to let coffee powder fall down through the outlet, and as said feeding device stops acting, said electromagnetic valve is released pushing the vertical lid to the outlet to shut it right away so that the coffee powder stored in will not be moistened to stick on the wall of the storing bottle. In addition, on the bottom of this automatic boiler a pressure switch is set to control the action of an electric heater is still filled with some liquid coffee, its weight may press said pressure switch to cause said electric heater to heat up the coffee pot keeping it warm.
