Abstract

A liquid stirrer includes a removable first liquid container to contain a liquid; a second liquid container having a capacity less than that of the first liquid container; a fluid path between the first liquid container and the second liquid container; a reversible pump disposed on the fluid path; a sensor to detect an amount of the liquid inside the second liquid container, in which the liquid reciprocally moves between the first liquid container and the second liquid container; and a controller to control the reversible pump, based on readings from the sensor, such that a moving amount of the liquid does not exceed the capacity of the second liquid container and that the second container does not go empty.
