Abstract
A pesticide residue removal device for a refrigerator, and a refrigerator are provided. The pesticide residue removal device includes: an ozone generator configured to generate ozone; an ozone water container configured to store water therein, where the ozone water container communicates with the ozone generator, so that ozone is dissolved into water of the ozone water container to obtain ozone water; and an atomizer communicating to the ozone water container, receiving and atomizing the ozone water, and supplying the ozone water to a storage space of the refrigerator. The generated ozone water is atomized to fully fill the entire storage compartment of the refrigerator to achieve effective pesticide residue removal and sterilization; ozone water can be prepared on demand to reduce waste; and people are well prevented from getting harmed at an excessive ozone concentration.
