  • Patent number: 5709166
    Abstract: The refrigerated automatic fish feeder is an insulated cylindrical container having a removable cover and a motor driven rotating food tray. The food tray has food tray compartments to hold food and each food tray compartment has a trap door to allow dispensing of food at predetermined time intervals. The insulated container has a food drop door which opens at the same time as the trap door to allow the food to drop from the fish feeder into a fish tank. The fish feeder is cooled by use of a thermal electric device thermally connected between an external heat sink with a fan to dissipate heat and an internal heat sink. The movement of the food tray to dispense food and the operation of the thermal electric device for cooling is accomplished by an operation and control circuit having a fail safe circuit.
