Energy-saving fresh air handling unit and purifying and filtering device thereof

Abstract

The energy-saving fresh air handling unit comprises a machine box, an isolation plate is fixedly installed in the machine box, a first filter plate and a second filter plate are fixedly installed on the two sides of the isolation plate correspondingly, and filter screens are fixedly installed on the inner side of the first filter plate and the inner side of the second filter plate correspondingly; a first driving rod, a second driving rod, a first auxiliary rod and a second auxiliary rod are rotationally connected to the two sides of the isolation plate correspondingly, and on the specific filtering device, the inner side walls of the air inlet pipe and the air outlet pipe installed indoors can be cleaned through the arranged cleaning brushes, so that dust existing in the fresh air handling unit in the using process is reduced, and the use safety of the fresh air handling unit is improved. The cleaning brush is arranged in the outer barrel, dust on the cleaning brush can be self-cleaned more conveniently through the rotation effect of the inner barrel in the outer barrel, the dust on the cleaning brush can be collected and treated through the storage box, and the self-cleaning and filtering effects of the whole device are improved.

Description

technical field [0001] The invention relates to the technical field of fresh air units, in particular to an energy-saving fresh air unit and a purification filter device thereof. Background technique [0002] The fresh air unit is an air-conditioning device that provides fresh air. The working principle is to extract fresh air outdoors and send it to the room through the fan after treatment such as dust removal, dehumidification (or humidification), cooling (or heating), etc., and replace the original indoor air when entering the indoor space. There are following defects: [0003] In the traditional fresh air unit, after the filter device in the fresh air unit filters the gas entering the fresh air unit, the filter and the interior of the fresh air unit cannot be cleaned, resulting in the overall fresh air unit being used for a period of time. And the effect of filtering function is reduced, while the traditional fresh air unit cannot more effectively self-clean the filter...
