An indoor fresh air device

Abstract

The invention discloses an indoor fresh air device. The device comprises a box body, an outdoor air chamber, an air exchange chamber, a solution chamber, a gas and solution exchange chamber, a solution distribution device, a fog blocking device and a draught fan, wherein the outdoor air chamber, the air exchange chamber, the solution chamber, the gas and solution exchange chamber, the solution distribution device, the fog blocking device and the draught fan are sequentially arranged in the box body form bottom to top; an outdoor air inlet is formed in one side of the outdoor air chamber, an indoor air returning chamber isolated from the outdoor air chamber and a plate chamber heat exchanger adjacent to the indoor air returning chamber are arranged in the air exchange chamber, an air outlet is formed in the side wall, with the plate type heat exchanger, of the air exchange chamber, an indoor air inlet grating is arranged on one side of the indoor air returning chamber, a solution box is arranged in the middle of a solution chamber, a water pump is arranged in the solution box and used for conveying a solution in the solution ox into the solution distribution device, the solution is distributed through the solution distribution device and returns to the solution box through a flow guide groove in the bottom of the gas and solution exchange chamber, and a channel allowing air to flow away is formed in the position, on the periphery of the solution box, in the solution chamber. The indoor fresh air device has the beneficial effects that internal circulation is achieved, outdoor fresh air can be introduced into a room, a filter element does not need to be replaced, no consumable is consumed, and the indoor fresh air device is green and healthy.

Description

technical field [0001] The present disclosure generally relates to the field of air purification, and specifically relates to an indoor fresh air device. Background technique [0002] The existing air purifiers generally have the following types: 1. Electrostatic dust collection type; 2. Electronic dust collection type; 3. Ozone type; 4. Anion type; 5. Filter element type; 6. Activated carbon adsorption type; 7. Comprehensive type . [0003] The electrostatic precipitating air purifier uses plastic fibers or fine-mesh metal mesh with electrostatic charge to absorb the polluted particles passing through the filter to achieve the purpose of improving the polluted particles in the indoor air. The filter screen needs to be cleaned frequently, otherwise the purification efficiency will decrease with the increase of use time. [0004] The electronic dust-collecting air purifier uses high voltage to charge the polluted particles, and when the charged polluted particles pass throu...

AI Technical Summary

Problems solved by technology

[0010] No matter what kind of air purifier mentioned above, there are the following defects: 1. Frequent cleaning of the filter screen is required, which increases the workload; 2. Frequent replacement of the filter element is required, which increases the cost; 3. Some air purifiers, such as negative ion purification methods, will cause secondary pollution ; 4. Some air purifiers such as negative ion or ozone will produce harmful gas, which is harmful to human health
