  • the present invention relates to a constant-temperature container having a refrigeration cycle of downward blowing, and more particularly to a constant-temperature container provided with an ozone generator and a negative ion generator.
  • Constant-temperature containers which are generally called cool containers, maintain the inside of the refrigerator at a constant temperature in order to maintain the freshness of fresh foods for a long period of time, thereby suppressing the life activities (respiration, etc.) of the fresh foods.

  • the corrosion of perishable products due to fungi (molds and bacteria) that grow at low temperatures will occur.
  • ethylene gas adsorbents were conventionally stored in a refrigerator to keep freshness from dropping.However, ethylene gas adsorbents must be collected and replaced each time fresh goods are transported. If the user forgets to replace the battery and keeps using it, there is a problem that the bag is torn and the bead-shaped adsorbent spills into the refrigerator.
  • ozone is oxidized, decomposed, and sterilized by floating in the air or adsorbing to dust and bacteria attached to walls and fresh products. Even if there is a metal plate or the like, it is not affected by this. Negative ions, on the other hand, have the property of repelling each other and spreading in space, but have the property of being rapidly consumed when passing through a narrow space. In addition, if a metal plate or the like is in the vicinity, it will not be adsorbed by the metal plate and the sterilization effect cannot be expected.
