Residential air purification fresh air machine provided with coaxial different-direction valve blades and adjustable in fresh air returning volume

Abstract

The invention discloses a residential air purification fresh air machine provided with coaxial different-direction valve blades and adjustable in fresh air returning volume, and belongs to the field of indoor air purifying. The residential air purification fresh air machine comprises a main fresh air machine body which is integrated with a purification function module and a power module and is adjustable in fresh air returning volume, a circuit control module used for relay controlling, electric signal converting and protection function starting, and a control and display panel used for receiving all parameter sensing signals, displaying the parameter value and selecting a purification mode. The circuit control module is fixed to the side surface of the main fresh air machine body and is connected with the control and display panel through a signal transmission line. The control and display panel is connected with an indoor parameter sensor. The fresh air returning volume is adjusted through rotating of the coaxial different-direction valve blades located in the main fresh air machine body. The residential air purification fresh air machine is integrated with the functions of removing haze and aldehyde and reducing the concentration of carbon dioxide and can effectively meet indoor air quality standards, so that a healthy indoor living environment is built.

Description

technical field [0001] The invention belongs to the field of indoor air purification, in particular to a residential air purification fresh fan with coaxial fresh return air volume adjustment. [0002] technical background [0003] The survey found that urban dwellers spend about 90% of their time indoors. Therefore, indoor air quality (Indoor Air Quality, IQA) will play a very important role in human health. However, the current situation of indoor air quality in my country is facing multiple difficulties. [0004] On the one hand, in recent years, mainly by PM 2.5 The resulting smog weather frequently invades China, and almost all large and medium-sized cities are spared. Global Atmospheric PM Captured by Satellite 2.5 The concentration distribution map shows that the PM in my country's atmospheric environment 2.5 The concentration exceeds most parts of the world and far exceeds the standard value recommended by the World Health Organization (WHO). All buildings in th...

Problems solved by technology

In addition, individual indoor occupants have different thresholds for different air quality perceptions. Existing fresh air fans have limited functions, and there is little feedback control to meet users' needs for different concentration thresholds of harmful gases or particulate matter in the air.

[0010] To sum up, in residential indoor purification occasions, due to the lack of functions of the existing fresh air fans, it is impossible to fully reflect the people-oriented concept of healthy home, resulting in the waste of some resources
