Abstract
A cleaning device for contact lenses includes a housing having a cleaning chamber, a stirring device for generating a liquid flow within the cleaning chamber, a heating device for boiling a liquid in the cleaning chamber, a feeding device for feeding the liquid into the cleaning chamber, a discharging device, a feeding amount detecting device for detecting a feeding amount of the liquid which is fed into the cleaning chamber, an operation controlling device for giving a signal to the stirring device, the heating device, the feeding device and the discharging device in response to the feeding amount of the liquid detected by the feeding amount detecting device, respectively and for performing a cleaning process, plural rinsing processes and a boil process. The feeding amount detecting device has a binary output type of liquid level sensor which detects a single liquid level in order to control a first feeding amount in the cleaning process, the last rinsing process and the boil process and a feeding timer which detects a feeding time for controlling a second feeding amount in the other of rinsing processes to be smaller than the first feeding amount. It is thus possible to decrease the consumption rate of the liquid without increasing the size of the device and complicating the structure of the device.
