technical field

The utility model relates to a dust-removing and smoke-removing purifier for a kitchen, in particular to a honeycomb electric field dust-removing structure of an electrostatic kitchen purifier.

Background technique

The electrostatic kitchen purifier uses an electrostatic field to remove the oil fume. The principle is that when the airflow enters the high-voltage electrostatic field, under the action of the high-voltage electric field, the oil fume gas is ionized, the oil mist is charged, and moves to the positive plate of the electric field and is collected in the The pole plate flows to the oil collecting pan under the action of its own gravity, and is discharged through the oil discharge channel. The anode plates of most electric fields are cylindrical. In order to improve the uniformity of the electric field, people in the industry have made a lot of efforts, such as CN 200987998Y, which discloses a pole plate of a hexagonal structure of an electrostatic dust removal and tar removal device.

The wire is easily bent and deformed after relaxation, and the uniformity of the electric field intensity is difficult to achieve the expected effect.
