ABSTRACT:
An espresso/cappuccino machine includes an upper container defining an upper chamber therein, a lower container defining a lower chamber therein, and a selector valve. A first pipet extends from nearly a bottom of the upper chamber to outside of the upper chamber. A first heating element with a first thermal control element is disposed in the bottom of the upper chamber. A second heating element with a second thermal control element is disposed in the bottom of the lower chamber. A second pipet communicates the upper chamber and the lower chamber. A check valve is provided in the second pipet such that fluid is only flowable from the upper chamber to the lower chamber. The selector valve has a first port in fluid communication with an opening on the upper container above an upper limit of water level in the upper container, a second port in fluid communication with a steam pipe, and a third port in fluid communication with a first end of a third pipet which has a second in fluid communication with a second opening on the lower container above a water level in the lower chamber. The selector valve has a lever to block the third pipet or to communicate the third pipet to either the upper chamber or to the steam pipe.
