STERILIZING APPARATUS

摘要

A sterilizer (20) is provided having a steam filled sterilizer chamber (24) for sterilizer articles placed within the chamber (24). An electronic air valve (186) is provided to control the venting rate of the steam is vented back to a water reservoir (140) after the articles have been sterilized. The electronic air valve (186) also vents the chamber (24) in a controlled manne r during the heat up portion of the sterilization cycle to obtain an optimum saturated steam environment with the chamber (24) for the sterilizing proces s. The sterilizer (20) has pre-programmed and programmable sterilization cycles . And the drying times of each of these cycles is programmable by a user. The programmable sterilization cycles also provide a programmable vent rate whic h may be selected by the user to minimize damage to the sterilized articles. A steam condensing coil (200) is associated with the water reservoir (140) to minimize pressure build up within the water reservoir (140). The sterilizer (20) uses sensed pressure within the sterilizer chamber (24) to control heating of the chamber (24) to a predetermined sterilization temperature set point during a sterilization cycle. A motor (114) controls a door lock mechanism to open the door (32) of the sterilizer (20) following the sterilizing portion of thesterilization cycle.
