た。 This type of steam sterilizer injects a predetermined amount of clean water into the chamber through a filter, and then heats the stored water to boiling, filling the chamber with high-temperature, high-pressure steam, thereby sterilizing the product. It sterilizes and disinfects objects, and the sterilization process from water injection to completion of sterilization is automatically performed. A predetermined amount of water is injected through the filter by a water level detection device installed at the bottom of the chamber, and when it is detected that a predetermined amount of water has been injected, the water injection valve is automatically closed. This occurs after the water injection valve is closed, and the heater is automatically energized to heat and boil the stored water. However, if the filter is used for a long period of time and dust or limescale adheres abnormally to the surface of the filter, causing clogging, the amount of water injected will be reduced, and the next step will be difficult because the specified amount of water will not be injected no matter how long it takes. The electricity supply to the heater during the sterilization process was not started, which was not preferable.

ものである。 Figure 2 is an explanatory diagram showing the water injection process of such a sterilizer, in which the on-off valve B is opened by the start signal A to start water injection.
and starts water injection timer C. The water injection timer measures the time until the water level detection signal D is received, and the water injection timer C is set in advance with a time width required for water injection into the chamber 1 to complete the injection. The water level detection signal D
If the input time is before the preset time range of the water injection timer C, dry cooking will occur when the next sterilization process starts even though the specified amount of water has not been obtained at all. This is dangerous, and in this case, the abnormality confirmation circuit G closes the on-off valve F and at the same time activates the abnormality display circuit H to notify the user of the abnormality.

良好なる滅菌処理が行なえるものである。 As mentioned above, the steam sterilizer of the present invention automatically injects water into a chamber for storing objects to be sterilized through a filter, detects a predetermined amount of water with a water level detection device, and heats and boils the injected and stored water. An automatic system is used to sterilize the object to be sterilized using high-pressure steam generated in the chamber, and a water injection timer is set in advance from the start of water injection to a water injection time range necessary for injecting a predetermined amount of water into the chamber. If the water level detection device is activated later than the set time range, a display prompting cleaning of the filter, etc. is displayed, so it is possible to know in a short time that the water injection process will not proceed. At the same time, the filter can be cleaned reliably, and the water injected into the chamber is always clean and can be sterilized well.
