ABSTRACT:
The invention is aimed at provision of a beverage extraction apparatus in which the cylinder for extraction is kept clean and, thus, the quality of the extracted beverage is maintained without periodical or frequent maintenance for cleanness. A portion of cleaning liquid overflowing from the upper chamber (mixing chamber) is drained by using a draining trough and a pipe. A valve is interposed between the upper chamber and the extraction chamber. When the valve is closed, the cleaning liquid supplied to the upper chamber in excessive amount overflows from the chamber and drained. When the valve is opened, the cleaning liquid flows from the upper chamber into the extraction chamber. Thereby, both chambers are cleaned efficiently.
