A fresh-keeping refrigerator

By incorporating a porous microfluidic chip and a negative ion generator inside the refrigerator, combined with water electrolysis and photocatalyst, sterilization and pesticide decomposition without dead angles are achieved inside the refrigerator. This solves the problems of incomplete sterilization and food oxidation, improves sterilization efficiency and food preservation, and reduces energy consumption and the frequency of consumable replacement.

AI Technical Summary

Technical Problem

Existing refrigerators do not sterilize thoroughly, leaving blind spots, and traditional methods can lead to food oxidation damage or pesticide residues, while also being energy-intensive and requiring frequent replacement of consumables.

Method used

Employing porous microfluidic chip technology, combined with water electrolysis and a negative ion generator, the microfluidic chip mixes silver ion-containing electrolyzed water mist and negative ion aerosol inside the refrigerator to achieve three-dimensional spatial coverage sterilization. It also utilizes photocatalysts to decompose pesticides and combines magnetic particles to recover the photocatalysts for recycling.

Benefits of technology

It achieves sterilization without dead corners inside the refrigerator, increasing the sterilization coverage rate to 98.7%, avoiding oxidative damage to food, increasing the vitamin C retention rate of strawberries to 89%, reducing energy consumption and extending the service life of consumables.
