Indoor air purifier

Abstract

The invention relates to an indoor air purifier comprising a main case, a first draught fan, a second draught fan, a filtering and purifying device and an air inlet baffle. The main case is provided with a first through hole, a second through hole and an indoor air inlet hole. The first draught fan is provided with a first air inlet and a first air outlet; the first air outlet is opposite to the first through hole in position and communicates with the first through hole; and the first air inlet communicates with the indoor air inlet hole. The second draught fan is provided with a second air inlet and a second air outlet; the second air outlet is opposite to the second through hole in position and communicates with the second through hole. The filtering and purifying device is located between the first draught fan and the second draught fan and covers the first air inlet and the second air inlet correspondingly. The air inlet baffle is installed on the filtering and purifying device; a fresh air channel is defined by the air inlet baffle, the filtering and purifying device and the inner wall of the main case; an air inlet of the fresh air channel is opposite to the first through hole in position and communicates with the first through hole; and an air outlet of the fresh air channel communicates with the second air inlet. By means of the indoor air purifier, outdoor fresh air is led into the main case through the fresh air channel, and therefore the problem that outdoor fresh air which is not purified contaminates the interior of the main case is solved

Description

technical field [0001] The invention relates to the field of air purification, in particular to an indoor air purifier. Background technique [0002] In the existing indoor air purifiers with the function of fresh air replacement, in the process of introducing outdoor fresh air, since there is no dedicated air duct, the unpurified fresh air will dirty the inside of the machine. When the user replaces the filter element, he will find that The inside of the whole case is full of dust, which is inconvenient to clean. Due to the unreasonable layout of the existing air purifiers, there are defects of high noise and small air volume. When people use them, the indoor noise is too large and the air purification effect is not ideal, which cannot well meet people's normal life needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an indoor air purifier aiming at the deficiencies of the prior art. [0004] The technical ...

[0002] In the existing indoor air purifiers with the function of fresh air replacement, in the process of introducing outdoor fresh air, since there is no dedicated air duct, the unpurified fresh air will dirty the entire interior of the machine. When the user replaces the filter element, he will find that The inside of the whole case is full of dust, which is inconvenient to clean

Due to the unreasonable layout of the existing air purifier, there are defects of high noise and small air volume. When people use it, the indoor noise is too large and the air purification effect is not ideal, which cannot well meet people's normal life needs.
