Description
Technical Field
The invention relates to the field of air purifiers, in particular to an air purifier with controllable internal and external circulation.
Background
In recent two years, the air purifier as a new electric appliance increasingly enters the public life and has important significance for protecting the physical and mental health of people. Although there are numerous brands on the market, in general, they can be classified into three categories: the first type is an internal circulation type and occupies most of the market share; the second type is fresh air type; the third type is a fresh air and exhaust type, 2 fans are arranged in the air conditioner, and a total heat exchanger is utilized to achieve the purpose of energy conservation.
These purifiers all have their drawbacks if analyzed from sources of pollution in the air. Important pollutants in indoor air can be classified into two main categories: one is dust particles, in which the main harmful component is PM2.5, the emphasis is from the outdoor atmosphere; the other is chemical substances, such as formaldehyde and the like, mainly from finishing materials and furniture. The internal circulation type air purifier only carries out indoor air circulation purification, can not isolate outdoor dirty air from continuously permeating from a gap between a door and a window, is unfavorable for normal breathing of an indoor human body if the door and the window are too tight, and has insufficient oxygen concentration, so the effect of the internal circulation type air purifier is limited to a certain extent. The fresh air type air purifier has the advantages that after outdoor air is continuously purified and treated, the fresh air type air purifier is sent into a room, so that the indoor sufficient oxygen concentration can be maintained, the outdoor dirty air infiltration can be well isolated, and if the fresh air amount reaches a certain value, the purifying effect on PM2.5 is better than that of an internal circulation type air purifier. However, the harmful substances such as formaldehyde generated in the room cannot be removed quickly. Compared with an internal circulation type air purifier, the fresh air and exhaust type air purifier has the advantages that fresh air is continuously provided, the defects that hazardous substances such as indoor formaldehyde and the like cannot be treated, and 2 fans operate to increase energy consumption and noise. Compared with a fresh air type air purifier, although energy and humidity exchange is carried out, the energy-saving purpose is not achieved substantially, and the energy-saving air purifier is obviously not required for families and commercial places unless the energy-saving air purifier is used in an environment with large indoor peculiar smell and needs to send a large amount of fresh air and remove dirty air.
Disclosure of Invention
In order to solve the problems, the invention provides an internal and external circulation controllable air purifier with fresh air and return air simultaneously.
The invention relates to an internal and external circulation controllable air purifier, which comprises a box body, wherein an air inlet and an air outlet are arranged on the box body, a high-efficiency filter screen, a chemical filter screen, a fan box, a medium-efficiency filter screen and a primary-efficiency filter screen are arranged in the box body, the high-efficiency filter screen is connected with the chemical filter screen, the chemical filter screen is connected with the fan box, the fan box is connected with the medium-efficiency filter screen, the medium-efficiency filter screen is connected with the primary-efficiency filter screen, the internal air inlet comprises an air return air opening and a fresh air opening, the adjusting mechanism comprises a fresh air door, an air return air door, a first linkage rod, a second linkage rod and a motor, the motor is connected with the second linkage rod, the second linkage rod is connected with the first linkage rod, the first linkage rod is connected with the air return air door, the second linkage rod is connected with the fresh air door, the first linkage rod and the second linkage rod are vertically intersected.
In the scheme, the first linkage rod is provided with the pulley, the second linkage rod is provided with the arc slope, and the pulley is arranged on the arc slope and can roll on the arc slope.
In the above scheme, the fresh air port is arranged on the side wall of the box body and is connected with the outside of the wall through the hose.
In the above scheme, the return air inlet is arranged on the side wall of the box body.
In the scheme, the return air inlet is arranged at the bottom of the box body.
In the above scheme, still include the ultraviolet lamp, the ultraviolet lamp is located in the air outlet.
In the above scheme, still include the photocatalyst net, the photocatalyst net is connected with high-efficient filter screen.
The invention has the advantages and beneficial effects that: the invention provides an internal and external circulation controllable air purifier with fresh air and return air simultaneously. Has the following advantages: 1. the device is provided with two interfaces, one is connected with outdoor fresh air, and the other is connected with indoor return air; 2. when the concentration of indoor PM2.5 is higher or indoor formaldehyde and the like need to be treated, the entering of fresh air is closed, and indoor air is circularly filtered by large air volume to enter an 'internal circulation state'; after a period of time, the indoor PM2.5 or formaldehyde concentration is reduced to meet the health requirement, at the moment, the fresh air door is automatically or manually opened to supply fresh air, the return air door is closed to enter an external circulation state, the rotating speed of the fan is regulated, and the aims of saving energy and reducing noise interference are fulfilled. Because the indoor main PM2.5 comes from outdoor air, the infiltration of outdoor dirty air can be isolated by maintaining indoor micro-positive pressure with a small amount of fresh air. The indoor fresh air and return air door can work simultaneously by internal and external circulation, namely, the fresh air and return air door are in a half-open state, and part of the fresh air and the return air are mixed and then are filtered, so that the continuous supplement of the indoor fresh air is met, and a small amount of PM2.5, formaldehyde and the like generated indoors can be rapidly treated.
