Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of steam sterilizer, concretely relates to a steam sterilizer steam blocking and spraying structure and steam sterilizer. BACKGROUND

[0002] At present, steam sterilizer meets the strict sanitary grade requirement, and austenitic stainless steel is generally used as the manufacturing material. However, this material has excellent corrosion resistance and mechanical strength, but some problems will be exposed under certain conditions. Especially when the sterilized items contain chloride ions, these ions will gradually diffuse in the cavity during the sterilization process, and then have adverse effects on the austenitic stainless steel.

[0003] Specifically, the liquid temperature in the steam sterilizer will gradually increase when it is working. With the increase of temperature, the water vapor containing chloride ions will continuously diffuse upwards and finally adhere to the top surface of the cavity. At this time, if the steam sterilizer adopts a rectangular design, the four corner areas will generate high tensile stress under pressure. This tensile stress combined with the chloride ions adhering to the top surface makes the top four corner areas become a high-risk area of stress corrosion. Moreover, with the passage of time, the grain boundaries and grains of the austenitic stainless steel will gradually corrode, forming tiny cracks, which will seriously affect the service life of the steam sterilizer, and even pose a threat to production safety.

[0004] Therefore, after completing the sterilization of the chlorine-containing items, the existing steam sterilizer will use manual method to regularly wipe and manually clean the inner cavity of the steam sterilizer. However, this method not only has the problem of low efficiency of manual cleaning, but also cannot effectively clean and protect the steam sterilizer in time because the cabinet body of the steam sterilizer is in a high temperature state after sterilization.
