Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Example:

As shown in Figure 1 and Figure 2, a kind of indoor fresh air system with air purification function provided by the utility model includes an indoor area 7, a main box body 9 and an air inlet area 1 in the main box body, a filter, a blower fan 6 and More than one pipeline, the fan 6 is a silent centrifugal fan, one end of the filter is communicated with the air inlet area 1, and the other end is connected with the fan 6, and the filter is provided with a primary filter 2, Electrostatic dust removal unit 3, silver ion filter 4 and activated carbon filter 5, primary filter 2 placed at the connection between the filter and the air intake area, activated carbon filter 5 placed at the connection between the filter and the fan, and the fan 6 An indoor air inlet duct 12 is provided, and the indoor area 7 is connected through the indoor air inlet duct. The indoor area is provided with an indoor air return duct 13. The indoor air return duct 13 includes a first air return duct 10 and a second air return duct 11. A return air duct 10 communicates with the air inlet area 1, and a second return air duct 11 is placed outdoors. The connection between the first air return pipe 10 and the air inlet area is provided with a regulating valve 8, and the air inlet area 1 is also connected with an outdoor air inlet area 14, and the air intake of the outdoor air inlet area 14 can be connected to the air inlet through the pipeline alone. Zone 1 is connected. In order to save the number of pipelines and save materials, the outdoor air intake area can also be connected to the air intake area 1 through a fork on the connecting pipeline between the regulating valve 8 and the air intake area 1.

Preferably, the fan 6 includes an air channel, a low-noise ball bearing motor and a centrifugal impeller 61, the air channel is made of flame-retardant and sound-absorbing materials, and the fan 6 is provided with a plurality of air channel openings communicating with the air channel 62.

A further description of the above-mentioned indoor fresh air system with air purification function: the fresh air introduced from the outside (outdoor air intake area) and part of the return air discharged from the room (by adjusting the valve to ensure that the fresh air introduced from the outside greater than the return air volume), after being purified into clean and fresh air by a four-layer filter, it is sent into the indoor area by a fan, and at the same time, the indoor dirty air (return air) is discharged. Part of the return air is directly discharged outside, and part of it is circulated and purified, which can reduce Energy loss, and at the same time meet the relevant national regulations on fresh air volume; the ratio of return air to outdoor fresh air can be adjusted manually or automatically by adjusting the "regulating valve". Filters using primary filter, electrostatic dust removal unit, silver ion filter and activated carbon filter have the following characteristics: 1. Primary filter: filter larger particles in the air, such as pollen; 2. Efficient electrostatic dust removal Unit, can remove more than 99% of PM2.5 in the air; 3. Silver ion filter: air sterilization and disinfection, eliminate part of the ozone generated by electrostatic dust removal; 4. Activated carbon filter: remove formaldehyde, stupid and other toxic gases in the air, It can be seen that the above-mentioned structure has a very good purification effect on the air and is beneficial to health.

For the fan, it can adopt a square structure, which is equipped with flame-retardant and sound-absorbing materials on the air inlet channel. At the same time, it uses high-quality low-noise ball bearing motors and optimized centrifugal impellers to achieve the best noise control. level. On the other hand, the machine body and the return air outlets of each room are connected by air inlet ducts, and are not directly installed in the bedroom, which can effectively solve the noise problem of using ventilation fans in the bedroom.

As shown in Figure 3, the air duct opening 62 is set on the fan to send fresh and clean air into the room through the pipe. The main pipe can be bifurcated, so it can meet the ventilation requirements of multiple rooms at the same time. Generally, one fan in a family can meet the requirements. Ventilation issues in multiple rooms.

For those of ordinary skill in the technical field to which the utility model belongs, on the premise of not departing from the concept of the utility model, its structural form can be flexible and changeable, and only a few simple deduction or replacement should be regarded as belonging to the structure of the utility model. The scope of patent protection is determined by the filed claims.
