Next, a method for treating an object to be sterilized according to the present invention will be described. In this invention, when the object to be sterilized is accommodated in the sterilization tank and sterilization is performed, a sterilizing treatment is performed after forming a water-repellent protective layer on the object to be sterilized. The protective layer is formed of, for example, a fluororesin, and after covering the entire object to be sterilized with the fluororesin,
The object to be sterilized is accommodated in the sterilization tank and sterilized. Here, the fluororesin is coated on the object to be sterilized by spraying with a spray or applying with a brush.

Therefore, according to the above-mentioned processing method, during the sterilization process, the condensed water does not remain on the object to be sterilized, so that it is possible to prevent the contamination of the object to be sterilized. In addition, since no stain is attached, it is not necessary to perform a cleaning operation using a cleaning agent harmful to the human body, especially for a metal object to be sterilized. Furthermore, even if dirt adheres, it can be easily wiped off.

By the way, the above-mentioned treatment method is more effective in preventing the adhesion of dirt when used in the above-mentioned sterilization apparatus. However, depending on the implementation, even in a sterilization apparatus not provided with the above-mentioned protective layer in the tank. Can be used. further,
In the sterilization apparatus, the object to be sterilized can be processed without performing the processing method.

As the material of the protective layer in the tank and the protective layer, various materials can be used as long as they have water repellency and heat resistance, in addition to the fluororesin.

Further, the present invention can be implemented not only in a steam sterilizer but also in various sterilizers such as a gas sterilizer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory longitudinal sectional view showing one embodiment of the present invention. The sterilization apparatus according to the present invention includes a sterilization tank 1 having an opening on the front surface, and has a structure that can be sealed by a door 2. A plurality of heating tubes 3, 3,... Are provided on the outer wall surface of the sterilization tank 1. A steam supply line 4 is connected to each of these heating tubes 3 and the sterilization tank 1. Are provided in the sterilization tank 1, and the objects to be sterilized 6, 6,... Are placed on these shelves 5, respectively.
Therefore, steam is supplied into each of the heating tubes 3 to heat the sterilization tank 1 from the outside, and steam is supplied into the sterilization tank 1 to heat-sterilize the objects 6 to be sterilized. Has become.

On the inner wall surface of the sterilization tank 1, an in-tank protection layer 7 having water repellency is provided. The in-tank protective layer 7 is formed by coating the inner wall surface of the sterilization tank 1 with a fluororesin, and has a predetermined thickness (about 1 mm).
0 μm) so as to cover the entire inner wall surface of the sterilization tank 1. The in-tank protective layer 7 has a predetermined heat resistance in consideration of the steam temperature during heat sterilization.

Therefore, by providing the in-tank protective layer 7, condensed water adhered to the inner wall surface of the sterilization tank 1 during sterilization processing flows smoothly downward and remains on the inner wall surface of the sterilization tank 1. Never do. The condensate flowing downwards is
The water is discharged from a drain pipe (not shown) provided on the bottom wall of the sterilization tank 1 to the outside. As described above, since the dirt mixed into the condensed water is not discharged to the outside together with the condensed water and remains, the dirt can be prevented from being attached to the inner wall surface of the sterilization tank 1. Also, even if dirt adheres to the surface of the in-tank protective layer 7, it can be easily wiped off.
