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.

First claim

What is claimed is:

1. A pesticide residue removal device for a refrigerator, comprising:
an ozone generator configured to generate ozone;
an ozone water container configured to store water, wherein 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,
wherein the ozone generator is attached to a top of the ozone water container, an ozone outlet is formed in an attached position of the ozone generator and the ozone water container, and the ozone generator supplies ozone to the ozone water container through the ozone outlet without a conduit between the ozone outlet and the ozone water container;
wherein the atomizer is attached to a side wall of the ozone water container, with an ozone water outlet being formed in an attached position of the atomizer and the ozone water container, or the atomizer is inserted into the ozone water container, with at least a part of the atomizer being located in the ozone water container and an ozone water outlet being formed in the part of the atomizer located in the ozone water container, and the ozone water container supplies ozone water to the atomizer through the ozone water outlet; and
wherein the atomizer comprises an atomization outlet arranged on a top of the atomizer, such that an ozone water mist formed by atomizing the ozone water is sent from the atomizer upwards from the atomization outlet into the storage space of the refrigerator.

2. The pesticide residue removal device for the refrigerator according to claim 1 , wherein
the ozone water container comprises a water inlet connected to an external water inlet pipe or a defrosted water outlet pipe of the refrigerator to supply external water or defrosted water of the refrigerator to the ozone water container.

3. The pesticide residue removal device for the refrigerator according to claim 2 , wherein
a water inlet valve is arranged at the position of the water inlet; and the water inlet valve is controlled to be opened and closed to control on and off of a water flow supplied to the ozone water container.

4. The pesticide residue removal device for the refrigerator according to claim 1 , wherein
the ozone generator is further configured to work during the outage of a compressor of the refrigerator at an interval of a preset time range from a startup and/or stop time of the compressor of the refrigerator.

5. A refrigerator, comprising:
a cabinet, in which a storage compartment is defined;
the pesticide residue removal device for a refrigerator according to claim 1 , which is arranged inside the storage compartment.

6. The refrigerator according to claim 5 , further comprising:
a storage drawer arranged inside the storage compartment, wherein the pesticide residue removal device is attached to the storage drawer.

7. The refrigerator according to claim 6 , wherein
the pesticide residue removal device is attached to a side wall of the storage drawer.

8. The refrigerator according to claim 6 , further comprising a control device, wherein the ozone water container comprises a water inlet and a water inlet valve which is arranged at the position of the water inlet and controlled to be opened and closed to control on and off of a water flow supplied to the ozone water container, the control device being configured to:
determine a water injection amount and an ozone injection amount on the basis of a volume value or a weight value of an object to be subjected to pesticide residue removal placed in the storage drawer; and
control the water inlet valve to supply, according to the water injection amount, water to the ozone water container; and/or
control the ozone generator to supply, according to the ozone injection amount, ozone to the ozone water container.
