Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-pressure steam sterilizer, and in particular, an object of the present invention is to dry an object to be sterilized without recontaminating it after a sterilization operation is completed.

To dry objects to be sterilized in this type of sterilizer, two methods are used: one method is to open the lid slightly and dry by natural convection, and the other method is to leave the lid closed and exchange air inside and outside by operating a valve.

However, the former method is difficult to automate because it requires opening the lid, and there is a possibility that the objects to be sterilized may be recontaminated due to the intrusion of room air.

The latter method is expensive and requires a sterile filter to be installed inside the valve.

The present invention aims to provide a new drying device that eliminates the drawbacks of the conventional example, and an embodiment thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a high-pressure steam sterilizer, which includes a chamber 2 with a rounded protruding back wall for storing objects to be sterilized, a heater 3 that heats water supplied to the chamber and generates steam, and a lid 4 that seals the chamber 2. It consists of

Reference numeral 5 denotes a concave water reservoir formed on the inner bottom wall of the chamber 2, to which a drain pipe 7 with a valve 6 is connected, and when the valve 6 is opened, the inside of the chamber 2 is communicated with the outside.

Reference numeral 8 denotes a cooler disposed near the water reservoir 5 in the chamber 2, and is formed by a meandering pipe with exits 9 and 10 extending outside the chamber 2, and is placed directly above the water reservoir 5 or in the vicinity of the chamber 2. It is located along the back wall of the

Therefore, during the sterilization operation, the valve 6 is closed and the cooler 8 is closed.
does not contribute to the sterilization process at all.

When the sterilization operation is completed and the water in the chamber 2 is discharged, the valve 6 is opened, a rubber hose is connected to the cooler 8, and city water is allowed to flow.

Then, since the temperature inside the chamber 2 is high, dew condenses on the surface of the cooler 8, and the water droplets are collected in the water reservoir 5 and discharged from the drain pipe 7.

In this way, the inside of the chamber 2 is dried. Therefore, it is more effective to use a drying heater for this drying.

As mentioned above, the high-pressure steam sterilizer according to the present invention has a cooler installed in the chamber to condense condensation and discharge the condensate, thereby eliminating the need for opening the lid and special valves, and preventing re-contamination of the objects to be sterilized. It is possible to dry sterilized items.
