Window-mounted fresh air purifier based on internal circulation mode

Abstract

The invention discloses a window-mounted fresh air purifier based on an internal circulation mode. The window-mounted fresh air purifier comprises a shell. An upper sealing fixed piece is distributedat the top end in the shell, and a lower sealing fixed piece is distributed at the bottom end in the shell. Outdoor air inlets are distributed in the outer side face of the shell. Air outlet cover plates are distributed on the inner side face of the shell. Indoor air outlets are distributed in the surface of the shell. A sealing partition plate is vertically installed between the upper sealing fixed piece and the lower sealing fixed piece. Heat conduction fins are installed at the two ends of the inner side face of the sealing partition plate. An air flow guide piece is installed at the centerof the inner side face of the sealing partition plate. An internal circulation cavity is distributed in the bottom of the shell and communicated with an outer cavity through a first air duct valve. An outdoor air outlet and an indoor air inlet are distributed in the two sides of the internal circulation cavity respectively. A whole filter element is sufficiently used, the applicability of the device is greatly improved, the device and user safety are sufficiently protected, and the installation process is convenient and rapid.

Description

Technical field [0001] The invention belongs to the field of purifiers, and in particular relates to a window-borne fresh air purifier based on an internal circulation mode. Background technique [0002] Most of the existing air purifiers are devices directly placed indoors, which can only purify the original indoor air, and cannot start the purification process from the source of the indoor air. It cannot increase the oxygen content of the indoor air and reduce the carbon dioxide content. , Without good sterilization ability, it is impossible to improve and optimize indoor air quality, and the design of the purifier itself cannot satisfy the indoor air purification work in large spaces. Most of the existing fresh air systems are installed in ducts, which need to pass through the walls and lintels, which will damage the structure of the house. After a long time of use, the ducts are easily polluted and difficult to clean, causing secondary pollution of indoor air. Summary of the...

Problems solved by technology

[0002] Most of the existing air purifiers are directly placed indoors, which can only purify the original indoor air, but cannot start the purification process from the source of the indoor air. It cannot increase the oxygen content of the indoor air and reduce the carbon dioxide content. , without good bactericidal ability, it is impossible to improve and optimize the indoor air quality, and the design of the purifier itself cannot meet the indoor air purification work in large spaces

Most of the existing fresh air systems are pipe-type installations, which need to go through the wall and lintel, which will damage the structure of the house. After a long time of use, the pipes are easy to pollute and difficult to clean, resulting in secondary pollution of indoor air
