[detailed description of the invention]

Now by reference to the accompanying drawings and embodiment the technical solution of the utility model is further elaborated, believe it is clearly for a person skilled in the art.

Existing air purifier, one substantially can only pipe room simultaneously; It requires to window ventilation, and excessively can change the temperature in room, the summer in winter increases air-conditioning and heating system live load, causes economic loss to user, and has ash and use the problems such as inconvenience.Air cleaning unit of the present utility model coordinates air exhauster, circulating fan to use, and adopts after tentatively being filtered by outdoor air and sends into indoor, drains the method ventilation of indoor outmoded gas from another simultaneously; And then further circularly purifying is done to room air; Have circulating fan to realize air Rational flow between room, make set of device can purify one between above room, the repetitive timing circuit that overall process is repeatedly worked by whole day controls, and brings convenience and economic interests to user.

Embodiment

As shown in Figure 1, this is the room in a set of two sleeping two Rooms, and when taking a breath, outdoor air enters the utility model air cleaning unit 1 through outer porthole, according to path flows shown in Fig. 2 arrow, through initial filter laggard enter indoor.The outmoded air of another indoor is by air exhauster 4 simultaneously, by outside another outer porthole discharge chamber.In order to air Rational flow, porose on the Room, room partition wall, realize forced air flow by circulating fan 2 and move.The flow direction of air as shown by the arrows in Figure 1; When purifying air, air exhauster 4 quits work, and air cleaning unit 1 works, and makes indoor air purification.Now circulating fan 2 makes air guided circulation, and between making often, room is all purified.Remote controller 3 and timing circuit are for setting and control the working time of each motor and magnetic valve 6.

As shown in Figure 2, when taking a breath, under the effect of blower fan 11, outdoor air, through the outdoor air air intake duct 7 of outer porthole ingress engine device, filters through first filter screen 8, by bypass channel 15 through blower fan 11, is discharged to indoor from exhaust outlet 12; After ventilation terminates, by the conversion of magnetic valve 6, close bypass channel 15 and outdoor air air intake duct 7.Room air indoor free-air diffuser 5 enters machine, through first filter screen 8, purifying layer, comprises the purification filterings such as smart filter screen 9, active carbon net 10, electrostatic precipitation, is discharged to indoor by blower fan 11 from exhaust outlet 12.

By porthole blower fan suction chamber outer air in embodiment, only filter through preliminary, after being filtered by visual dust (comprising PM2.5), enter a room, then discharge outmoded air from the porthole in another distant room and take a breath.Like this and method, the air that outdoor enters and the degree of mixing of outmoded gas that will discharge are minimum, and invalid ventilation volume is few, because the time of exchanging gas needed also is the shortest, decrease room thermal loss.After ventilation, proceed to cleansing phase, this work is the same with commercially available conventional indoor circulation air purifier.In order to improve air guided flowing, perforate between room, realizes forcing circulation with circulating fan, the air in each room is all purified.

Motor in above scheme and magnetic valve control by being with the timing controller 14 of remote controller 3.Thus Best Times can be selected to carry out taking a breath and purifying.Such as winter noon, user often goes to work, go to school, and air-conditioning or heating installation suspend, and indoor/outdoor temperature-difference is less again, now takes a breath, and indoor heat loss can be made minimum.Timer is that a large period sets motor and magnetic valve 6 working time respectively by a week, removes user from and takes a lot of trouble operation every day for purifying air.The setting of time can be undertaken by remote controller 3.

In scavenging period, several filter screen only has first filter screen work, first filter screen low price and usually can clean Reusability, does not thus have the problem of commercially available new wind type air purifier waste filter screen.This programme reduces air-conditioning, heating installation power consumption with rationally and only needing shorter time of exchanging gas to reach, and avoids the shortcoming adopting heat exchanger.
