Fresh air purifier

Abstract

The invention relates to a fresh air purifier which comprises a main shell, a fresh air passage, an air returning passage, an air intake and outtake fan, an air intake and outtake pipe, an air purifying device and an electric control part. The air intake and outtake pipe comprises an air intake pipe and an air outtake pipe which are sleeved with each other; the air intake and outtake fan comprises a motor, an air intake wheel and an air outtake wheel; a motor shaft is connected with the air intake wheel and the air outtake wheel respectively; the air intake wheel is arranged at the position that the fresh air passage is close to the air intake pipe, and the air outtake wheel is arranged at the position that the air returning passage is close to the air outtake pipe; the air purifying device is arranged in the fresh air passage behind the air intake and outtake fan and comprises an electrostatic precipitation device and an ultraviolet sterilization device; the electrostatic precipitation device comprises an anode plate, a cathode plate and an ionization device which is arranged at the air intake side of the electrostatic precipitation device; the ultraviolet sterilization device is arranged at the air outtake side of the electrostatic precipitation device. The fresh air purifier has simple structure and low cost, is conveniently installed and maintained, effectively ensures indoor ventilation and air exchange, air purification and sterilization and cleanness of the indoor air.

Description

Technical field: [0001] The invention relates to a fresh air purifier, which is mainly used for exchanging indoor and outdoor air, pre-purifying the air sent into the room from the outside, and recovering energy from the air discharged from the room to the outside. Background technique: [0002] At present, the most common method to solve indoor air pollution is to use air purification devices and indoor ventilation, such as air purifiers, air fresheners, fresh air ventilators, heat exchange fresh air fans, etc. Air purifiers and air fresheners can circulate and filter indoor air. To achieve a certain degree of cleanliness, fresh air ventilators and heat exchange fresh air fans achieve a certain degree of cleanliness through the exchange of indoor and outdoor air. Although air purifiers and air fresheners have air purification functions, they only circulate indoor air. Lack of fresh air is prone to hypoxia, the air purification core is easily saturated, and the cost of repla...

AI Technical Summary

Problems solved by technology

Although air purifiers and air fresheners have air purification functions, they only circulate indoor air. Lack of fresh air is prone to hypoxia, the air purification core is easily saturated, and the cost of replacing the filter element is high.

Although the fresh air ventilator has the function of fresh air exchange, but because there is no energy recovery device, it takes away all the heat while exchanging air, and the energy consumption is relatively large, which is not conducive to energy saving

Although the heat exchangers currently on the market have energy recovery devices and fresh air ventilation functions, they lack air purification devices, and the outdoor fresh air is sent indoors without any treatment, resulting in more indoor dust and outdoor pollutants (in air pollution Serious places are more obvious)
