ABSTRACT:
An apparatus for cleaning parts includes a tank having an liquid inlet opening and a liquid outlet opening therein to allow a liquid, such as water to enter and drain from the tank. The tank also includes an air inlet window and an air outlet duct for allowing a flow of air to pass therethrough. An air duct having an air pump connected thereto extends across the outside of the tank between the air outlet duct and the air inlet window to provide a flow of air through the tank. A heater is in the air duct to heat the flow of air. A first overflow wall extends across and spaced from the air inlet window to provide an overflow passage for carrying away any liquid which may overflow the wall and prevent the liquid from entering the air inlet window. A second overflow wall extends across and is spaced from the air outlet duct to form an overflow passage for carrying away any liquid which may overflow the second overflow wall and prevent such liquid from entering the air outlet duct. There are drains at the bottom of the overflow passages to carrying away any liquid which may enter the overflow passages. A basket for containing the articles to be cleaned is provided and can be inserted and supported in the tank. A reservoir for cleaning solution is connected to the tank and includes a metering pump for controlling the amount of cleaning solution fed to the tank. At least one ultrasonic transducer is mounted on the tank for ultrasonically vibrating the liquid in the tank, and a heater is mounted on the tank for heating the liquid.
