Purification device and refrigerator

Abstract

The invention relates to the field of discharge electrode purification, and discloses a purification device and a refrigerator. The purification device comprises a discharge electrode structure and apower supply connected with the discharge electrode structure, wherein the discharge electrode structure comprises a first electrode, a second electrode and an insulating medium (3); and the insulating medium (3) is located between the first electrode and the second electrode, and the insulating medium (3) is of a porous structure. Through the technical scheme, the insulating medium arranged between the first electrode and the second electrode can optimize and improve discharge to a certain extent, thus line discharge between the first electrode and the second electrode is converted into surface discharge, the efficiency of decomposing organic matter is improved, the discharge voltage is relatively low, generation of ozone is avoided or reduced, secondary pollution of the ozone is reduced,and the electrodes and surrounding components are protected.

Description

technical field [0001] The invention relates to air purification, in particular to a purification device and a refrigerator including the purification device. Background technique [0002] Refrigerators can be used to refrigerate, freeze food, and more. During use, the food and other items stored in the refrigerator can volatilize to produce organic molecules, and the residual pesticides on the surface of some fruits and vegetables will also volatilize, which makes the air inside the refrigerator smelly. Therefore, it is necessary to remove the organic molecules in the refrigerator. Ensure that there is relatively pure air in the refrigerator. [0003] The currently used purification device promotes the decomposition of organic molecules in the air into water and carbon dioxide through the discharge between electrodes to achieve the purpose of removing odors. In order to improve the discharge decomposition efficiency, the discharge voltage between the electrodes is often r...

AI Technical Summary

Problems solved by technology

In order to improve the discharge decomposition efficiency, the discharge voltage between the electrodes is often relatively large. Although the organic molecules in the air can be decomposed by the discharge, the oxygen in the air is transformed into ozone due to the discharge, causing secondary pollution to the air. , and ozone has a strong oxidation effect, which may chemically react with some parts inside the refrigerator, causing damage to the parts
