Document Type and Number:
Japanese Patent JP2015059480
Kind Code:

Abstract:
PROBLEM TO BE SOLVED: To quickly increase a temperature of a liquid when there is risk of the liquid in a casing coagulating.SOLUTION: A water supply device controller 500 is an operation device for controlling an operation of a liquid supply device 1000 having: a pump 200 in which an impeller and a suction port and a discharge port of a liquid are provided; and a motor 300 for rotationally driving the impeller. The water supply device controller 500 includes: a temperature detection unit 540 for detecting a temperature of a liquid in the pump 200 or a temperature correlated with the temperature of the liquid in the pump 200; and a control unit 550 for rotating the impeller in a rotation direction opposite from the rotation direction when discharging the liquid from the discharge port, when the temperature detected by the temperature detection unit 540 becomes lower than a first threshold value set in advance.
