Electrode plate assemblies, electrostatic devices and range hoods

Abstract

The invention discloses a plate electrode component, an electrostatic device and a range hood. The plate electrode component comprises a plurality of center connecting rods (2), a plurality of plate electrodes connected in series by the center connecting rods, a plurality of pitch varying telescopic sleeves (4) arranged on the center connecting rods in a sleeving manner, and pitch varying driving pieces (3); a plurality of spacing teeth (41) formed in the axial directions are formed in each pitch varying telescopic sleeve; each end of each plate electrode is arranged in a clamping groove (42) between the two corresponding spacing teeth on the two sides of the plate electrode; and the pitch varying driving pieces can drive the pitch varying telescopic sleeves to expand and contract, so as to adjust the plate electrode spacing between every two adjacent plate electrodes. The plate electrode component is in a novel integral component structure of which the plate electrode spacing can be adjusted and the plate electrodes can be connected in series for forming the plate electrode component. The spacing between the plate electrodes can be determined and adjusted according to a practical oil fume flow and a pollution level of a module in order to maintain a good oil fume purifying effect. In addition, with the adoption of the mode that the plate electrodes are connected in series for forming the plate electrode component, the disassembly and assembly are time-saving and are convenient and quick.

Description

technical field [0001] The invention belongs to the field of household appliances, in particular, the invention relates to an electrode plate assembly, an electrostatic device and a range hood. Background technique [0002] At present, it is common to use electrostatic oil filtering for range hoods on the market, which makes the oil separation degree of range hoods higher. The existing electrostatic oil filtering method is mainly realized by an electrostatic device. The electrostatic device generally includes an electrostatic ionization module and an electrostatic collection module arranged successively in the direction of oil fume passing. electrode plate. Among them, the electrostatic ionization module is used to discharge through the electrode plate, and the electrostatic collection module is used to provide an electrostatic field, so that the passing oil fume is collected on the electrode plate of the opposite polarity of the electrostatic collection module after being ...

Problems solved by technology

However, the distance between the electrode plates of the electrostatic device in the prior art cannot be adjusted, so it cannot adapt to this change, and some abnormal phenomena occur, resulting in the deterioration of the electrostatic ionization effect of the electrostatic ionization module, and even the breakdown of the electrode plates. phenomenon, and the collection effect of the electrostatic collection module will become worse, and the phenomenon of back corona will also appear

Ultimately, the performance of the electrostatic device decreases after a period of use, and the efficiency of oil fume purification becomes lower
