In addition, in the bipolar ion generator 400 used in the ion purification device of the dishwasher of the present invention, the emission electrode plate and the ground electrode plate are connected with current to form an electric field with precise dimensions, alternating current is adopted, electrons emitted from the emission electrode plate are led out of the medium blocking plate on the side where the electric field is grounded, and different-sign gas ions are generated, so that tableware in the dishwasher can be effectively sterilized and disinfected. Under the traditional single-stage ion airflow condition, the particle can be charged, bacteria attached to the particle can be electrified, however, the bacteria cannot be killed by changing the potential of the bacteria, and the bird cannot be killed by touching the electricity as if the bird falls on a high-voltage wire, and the reason is that no current is formed on the bird body. The abnormal gas ions generated by the bipolar ionizer of the present invention form a micro current capable of penetrating the cell wall of bacteria, thereby killing the bacteria, and it should be noted that the micro current formed here is less than 1mA, which is safe for human body.

According to the ion purification device for the dish washing machine, the ion sheet 410 is arranged in the support 300 between the fan 100 and the drying pipeline 200, when the tableware needs to be sterilized, the fan 100 and the bipolar ion generator 400 are started, air flow generated by the fan 100 enters the support 300, purified ion groups generated by the ion sheet 410 are carried into the drying pipeline 200 and enter the accommodating cavity in the dish washing machine together with hot air flow of a drying assembly, so that hot air drying and sterilizing functions of the dish washing machine are combined, hot air drying and sterilizing are carried out while drying and storing are carried out, cleanness and sanitation of the tableware are further ensured, and bacteria breeding and odor generation are avoided. In addition, the bipolar ion generator 400 used in the ion purification device of the dishwasher facilitates the installation, maintenance and replacement of the ion plate 410 by electrically connecting the plug 440 with the ion plate 410 in a pluggable manner, and when the ion plate 410 fails, only the plug 440 needs to be pulled down to replace the ion plate 410, and the power converter 450 and other circuit structures or electronic components in the dishwasher do not need to be replaced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
