LIQUID FOOD SUPPLY DEVICE, LIQUID FOOD SUPPLY METHOD AND COFFEE MAKER

摘要

PPROBLEM TO BE SOLVED: To improve a conventional liquid food supply device for transporting a liquid food, and sufficiently accurately monitor the liquid levels in a liquid food containers at the same time and at a low cost. PSOLUTION: The liquid food supply device is equipped with pumps 2a, 2b connected to the liquid food containers 4a, 4b for sending out the liquid food from the liquid food containers 4a, 4b and at least one sensor 5a, 5b for measuring the liquid level in the liquid food container, and is constituted to stop the pumping process of the pump according to whether the measurement signal of the sensor is smaller or larger than a prescribed measurement signal limit. Sensors 5a, 5b are formed as a pressure sensor, and the sensors are arranged so that the pressure in the liquid food containers 4a, 4b can be measured by the sensors. PCOPYRIGHT: (C)2009,JPO&INPIT
