Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the utility model, as detailed in the appended claims.

It should be understood that the terms of orientation, such as "upper", "lower", "top", "bottom", "front", "back", "side", etc., used in the embodiments of the present invention are based on the arrangement orientation of the air duct plate assembly, wherein the orientation of the air outlet is top or upper, the orientation of the air inlet is bottom or lower, the portion between the top and the bottom is side, the orientation of the decorative surface is front, and the orientation of the non-decorative surface is back. The embodiments of the present invention use these terms only for the purpose of describing structures and relationships between structures, and not for the purpose of describing absolute orientations, and therefore, should not be construed as limiting the utility model.

Unless defined otherwise, all technical terms used in the embodiments of the present invention have the same meaning as commonly understood by one of ordinary skill in the art.

Refrigerators are indispensable household appliances in human life, and in order to reduce bacteria and odor in refrigerators, an ion generator is generally used to sterilize and deodorize the interior of the refrigerators.

The ion generator, also called as air anion generator or anion generator, generates anions by using a method of boosting the power frequency voltage to the required voltage by using a high-voltage transformer, releases the anions to the surrounding air, performs sterilization by using the adsorption effect of the anions, and reduces the concentration of peculiar smell in the refrigerator.

The negative ions released by the negative ion generating device can charge particles such as smoke dust, germs, spores, pollen, flock and the like in the air and then are absorbed by the discharging integration device, and the action effect is better than that generated by pure physical modes such as filtration (even if a very fine filter hole material is used, solid particles smaller than the filter hole cannot be filtered, gaseous pollutants cannot be filtered) or adsorption (materials such as active carbon only have a selective adsorption function).

The related art ionizer generally arranges the electrodes and the rectifiers in a separated manner, and the wire connection between the separated components causes cumbersome wire arrangement work, increases loss, and is easily caused by poor wire contact to cause the operation failure of the ionizer.
