Abstract

An ultrasonic degreasing apparatus includes a cleaning section, a rinsing section, a hot water cleaning section, and a drying section. The cleaning section has an ultrasonic oscillator for oscillating ultrasonic waves in distilled water and a heater for heating the water, and performs a degreasing process including a cleaning process with respect to an object to be processed in the heated water by using ultrasonic waves. The cleaning section has a deaerating section for performing deaeration by circulating the distilled water. The rinsing section has an ultrasonic oscillator for oscillating ultrasonic waves in distilled water containing a rust preventive and a heater for heating the water, and performs a degreasing process including a rinsing process with respect to the object in the heated water by using the ultrasonic waves. The rinsing section has a deaerating section for performing deaeration by circulating the distilled water. The hot-water cleaning section has a heater arranged in distilled water, and performs a cleaning process with hot water with respect to the object in the distilled water heated by the heater. The drying section dries the cleaned object conveyed from the hot-water cleaning section.

Dependent claims

An ultrasonic degreasing apparatus comprising:

a cleaning section, having first ultrasonic oscillation means for oscillating ultrasonic waves in first distilled water and first heater means for heating the first distilled water, for performing a degreasing process including a cleaning process with respect to an object to be processed in the first distilled water heated by said first heater means by using the ultrasonic waves oscillated by said first ultrasonic oscillation means, said cleaning section having first deaerating means for performing deaeration by circulating the first distilled water;
a rinsing section, having second ultrasonic oscillation means for oscillating ultrasonic waves in second distilled water containing a rust preventive and second heater means for heating the second distilled water, for performing a degreasing process including a rinsing process with respect to the object, conveyed from said cleaning section, in the second distilled water heated by said second heater means by using the ultrasonic waves oscillated by said second ultrasonic oscillation means, said rinsing section having second deaerating means for performing deaeration by circulating the second distilled water;
a hot-water cleaning section, having third heater means arranged in third distilled water to heat the third distilled water, for performing a cleaning process with hot water with respect to the object, conveyed from said rinsing section, in the third distilled water heated by said third heater means;
and
a drying section for drying the cleaned object conveyed from said hot-water cleaning section.
