滅菌、乾燥させる高圧蒸気滅菌装置に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a high-pressure steam sterilizer, which can be used to sterilize medical gauze, bandages, cotton clothing, and other medical articles in hospitals and other places for a short period of time. Related to high-pressure steam sterilization equipment for sterilization and drying.

があり、この乾燥のためには、圧力容器内の蒸気を一旦
排出し、圧力容器内を再び高温にして乾燥させている。The sterilization process is as follows: - For boat fishing, the object to be sterilized is placed in a pressure vessel (cylinder) that can withstand high temperature and high pressure steam, and the pressure and temperature suitable for sterilization are set in a constant steam atmosphere of the pressure vessel. This is done by exposing yourself to time. Since the object is exposed to steam, it is necessary to dry the object to be sterilized after sterilization. To do this, the steam inside the pressure vessel is once discharged, and the inside of the pressure vessel is heated to high temperature again and dried. There is.

に排出している。(Problems to be Solved by the Invention) These conventional sterilizers include a pressure vessel, a water supply means for supplying water into the pressure vessel, a pressure vessel for heating and vaporizing the supplied water, and a pressure vessel for drying the water. There is a heater inside for heating. That is, water supplied into the pressure vessel is heated and vaporized by a heater, creating a high-temperature, high-pressure sterile atmosphere inside the pressure vessel. In order to improve heating efficiency, the heating heater is set at the bottom of the pressure vessel.
For drying efficiency, the steam outlet is provided at the top of the pressure vessel, and the steam is sucked out using a vacuum installed outside the pressure vessel.

うようになっているから、加熱ヒーターが過熱状態とな

反し、加熱ヒーターから離れた場所では一定の温度以上
に上昇せず、圧力容器内の温度が不均一な状態となる。However, with this conventional sterilizer, the drying process after sterilization is performed by heating the heater, which not only causes the heater to overheat, but also causes high temperatures near the heater. On the other hand, in areas far away from the heater, the temperature does not rise above a certain level, and the temperature inside the pressure vessel becomes non-uniform.
そのため、加熱ヒーター近くではガーゼ、衣類等の被滅

きないこともあった。Therefore, objects to be sterilized, such as gauze and clothing, are burned near the heating heater, making it difficult to reuse them, and moreover, they may adhere to the heating heater, requiring removal work. In addition, in a place far from the heating heater, the temperature will not reach a high temperature and the dry state will not be sufficient, so even if it is taken out of the pressure vessel, it will not be used again.
Sometimes I couldn't.

ないことかあった。In order to solve this problem, there is a method in which dry air is forcibly blown after sterilization by high-pressure steam is completed, as described in Publication No. 18903/1983. However, this method simply forcefully supplies dry air into the pressure vessel, and the objects to be sterilized held in the pressure vessel obstruct the circulation of dry air within the pressure vessel, causing the entire object to be sterilized to be sterilized. Or maybe it wasn't drying on average.

のではなかったのである。For these reasons, the inventor of the present invention considered ways to improve the deficiencies of conventional sterilizers and found that the cause was due to the steam suction method in the drying process and the fact that the drying air was not flowing smoothly. Ta. In other words, when discharging steam after sterilization, even if it is sucked in from the outside or even if dry air is forcibly supplied, it is only possible to create an air flow in some parts of the pressure vessel. However, the entire inside of the pressure vessel was not kept at a constant temperature.

The purpose is to prevent burnout of objects to be sterilized near a heating heater.
