Fresh air integrated type air purifier

Abstract

The invention discloses a fresh air integrated type air purifier. The integral design of the air purifier and a fresh air fan is adopted. The purifier is communicated with outdoor fresh air and can be arranged in a vertical or wall-mounted mode, and an exhaust opening is not formed. An air inlet cavity is formed in the lower portion of the shell, a fresh air port and air return ports are formed in the lower portion of the shell and are communicated with the air inlet cavity, and the multiple air return ports can be included to be communicated with other rooms or space. The fresh air integrated type air purifier comprises an HEPA high efficiency filtering module, a primary efficiency filtering module and a medium-efficiency filtering module or a benzene-removing filtering module or a methanal-removing filtering module or a TVOC-removing filtering module or a bacteria-removing filtering module or a stink-removing filtering module or a combination of the medium-efficiency filtering module, the benzene-removing filtering module, the methanal-removing filtering module, the TVOC-removing filtering module, the bacteria-removing filtering module and the stink-removing filtering module. The diameter size phi of a fresh air hole or a fresh air pipe on a wall is 30-90 mm. A special centrifugal fan is adopted, and the shell is designed in a curved mode according to pressurizing and is provided with a guiding plate. According to the fresh air integrated type air purifier, the air opening pipe diameter is reduced, pipeline losses are reduced, fan power is reduced, electricity and energy are saved, silence is achieved, installation is facilitated, and use is convenient. Meanwhile, the purifying effects that PM 2.5 is removed and the index can reach the level of 0.1-0.5 micron are achieved.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to an integrated air cleaner with fresh air function. Background technique [0002] Prior art 1, ZL 201310671915.0, such as figure 1 As shown, the working principle of its embodiment is as follows: [0003] The outdoor air is sucked into the inside of the fresh air box 10 through the air inlet fan 22 by the air inlet duct 20 and the air inlet 21, and is purified into fresh air by the fresh air purification device 23 and the heat exchanger 60, and the fresh air is sent to the fresh air through the fresh air. The air outlet 24 and the fresh air supply pipe 25 of the adjacent room are delivered to the adjacent room (the room adjacent to the wall where the fresh fan is installed); [0004] The indoor air is passed through the exhaust fan 32 by the air return port 34, the return air filter 33, the heat exchanger 60, the exhaust fan 32, [0005] The air outlet 31 and the exhaust duct 30...

AI Technical Summary

Problems solved by technology

[0012]1. The filtering effect has not been disclosed, the simple function of sending fresh air and positive pressure cannot achieve the effect of air filtering, and the substantial progress of air purifiers should It is an improvement on the basic functions including air purification. For example, the present invention adopts a structure integrating fresh air and return air while using a HEPA high-efficiency filter module.

[0013]2. The apertures of the fresh air and return air pipelines have not been designed, but adopt general standards. After the pipe diameter is reduced, the function of oxygen supply cannot be realized, and the large Due to the size of the pipe diameter, the power of the fan cannot be reduced, resulting in high noise, which is not conducive to the home and office environment

[0014]3. Due to the different airflow directions, the filtration efficiency is different. At the same time, the filter module of the prior art cannot achieve a good cleaning effect. In fact, the market Similar products used on the Internet have proved that their PM2.5 removal index cannot reach the level of the present invention. In the case of severe smog weather in the country, it cannot even reach the national standard. At the same time, it cannot solve the problem of reducing heat exchange and maintaining room temperature. The problem
