Abstract

The invention discloses a high-voltage electrostatic field generator with a fresh-keeping function and a refrigerator with a fresh-keeping function. The high-voltage electrostatic field generator withthe fresh-keeping function comprises an inverter circuit for inverting a safety DC voltage into high AC voltage with predetermined range for output; an oscillating circuit connected with the invertercircuit and used for generating a sinusoidal AC signal of certain frequency and amplitude and a vibrational signal in space; a plurality of high voltage electrodes connected with the oscillating circuit and used for generating ozone by supplying low-frequency vibration; a stepdown filter device connected with the inverter circuit and used for stepping down and filtering the AC voltage that is boosted. The safety DC voltage, such as 12 V, is inverted into the AC voltage of 1000-5000 V through the inverter circuit; the input safety DC voltage, such as 12 V, is low, providing good safety and reliability; the power consumption is lower, so that energy saving and electricity saving are achieved; the efficiency of high-frequency boost conversion for direct current is high, and conversion startup speed is high.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a high-voltage electrostatic field generating device with a function of keeping freshness and a refrigerator. Background technique [0002] At present, only a few refrigerators use the electric field to keep fresh, use the transformer to increase the AC voltage of 220V to 800-3000V AC voltage, and then go through the output controller to the discharge source. [0003] The existing electrostatic fresh-keeping refrigerator uses a transformer to raise the AC voltage 220V to 800-3000V AC voltage, and the input voltage is relatively large, which is prone to electric shock accidents. Moreover, the power consumption is large and the efficiency is low. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] In view of the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a high...
