Device for washing and disinfecting medical ware

摘要

The heater (6) is a steam generator below a steam head space (2) of the water tank. The head space is separated down to the lowest water level (10) by a partition (3) forming a steam barrier. Steam forming above the water level (9, 10) of the evaporator is led through a steam line into the cleaning chamber (13). Preferred features: The head space is below the water supply (4) to the tank. Sensors and solenoid valves in the hot and cold water pipes control the water level. The partition is a metal sheet bulkhead, which is readily removed for maintenance purposes. The heater is contained in an open-topped tank (7). A lime scale inhibitor vessel (15) is connected to this tank. The steam line extends from an overflow (5) of the main tank, located in the steam head space. The pumping system for hot water from the main tank includes valves and injection nozzles in the cleaning chamber. Solenoid valves supply the nozzles as required. Cleaning fluid (14) is dosed on the suction side of the pump. The main water tank and hot water system can be emptied, allowing it to be steamed for disinfection. An overflow system (17) is included, preferably reaching the lowest point of the U-bend (16). An over pressure vent valve (18), preferably a solenoid valve, is connected to the top of the cleaning chamber, and vents to the exterior or the drain. A variant of the water supply inlet is described.
