Sterile purifying fresh-keeping device, sterilization method and refrigerator

Abstract

The invention provides a sterile purifying fresh-keeping device, a sterilization method and a refrigerator. The sterile purifying fresh-keeping device comprises an antioxidative seal box, an ozone generator, a sterilizing filter and an ozone removing filter. The antioxidative seal box is provided with a pick-and-place opening and a cover body used for sealing the pick-and-place opening, and the antioxidative seal box is further provided with an air inlet and an air outlet, wherein the air inlet is formed to introduce air outside the antioxidative seal box into the antioxidative seal box, and the air outlet is formed to exhaust air in the antioxidative seal box out of the antioxidative seal box; the ozone generator is arranged to provide ozone for the antioxidative seal box so as to conduct sterilization on articles in the antioxidative seal box; the sterilizing filter is arranged on the air inlet and used for conducting sterilization on air flowing through the sterilizing filter; the ozone removing filter is arranged on the air outlet and used for removing the ozone in air flowing through the ozone removing filter. According to the sterile purifying fresh-keeping device, the sterilization method and the refrigerator, the ozone is used for conducting sterilization on the articles, the ozone can be rapidly and effectively removed by means of the ozone removing filter through an air circulating mode, and therefore sterilization can be conducted on the articles by means of the ozone with higher concentration.

Description

technical field [0001] The invention relates to the technical field of sterilization, in particular to an aseptic purification and preservation device, a sterilization method and a refrigerator. Background technique [0002] The function of the refrigerator is to provide a low temperature environment to prolong the storage time of items. The food stored in the storage room of the refrigerator, especially the food stored in the cold room, will still spoil after a long time. Food spoilage is mainly caused by bacteria and molds. In order to kill bacteria and molds, people initially installed adsorption devices in refrigerator storage compartments to absorb odors. Bacteria and molds do not play any role. It only absorbs the odor produced by microorganisms and has no effect on food preservation. [0003] In order to thoroughly sterilize the storage compartment of the refrigerator, it has been disclosed in the prior art to use ultraviolet rays and ozone to kill bacteria in the r...

Problems solved by technology

However, ozone is harmful to the human body, and its odor is relatively heavy. The ozone sterilization technology currently used on refrigerators uses ozone with a low concentration, and the bactericidal effect is not significant enough.
