Background technique
In recent years, since economic fast development and urbanization process are accelerated, atmosphere pollution is on the rise.Chinese most
Number city has had already appeared long-term haze weather.The increase of PM2.5 concentration, directly resulting in haze weather and taking place frequently has in mist
It is malicious, harmful substance to be significantly increased, seriously threaten the health of the mankind.In this case, conventional household is comfortable
Property air-conditioning have been unable to meet the needs of people, health, comfortable, environmental protection have become the target of modern air conditioning development.
For common air-conditioning, to guarantee its air-conditioning effect, it is desirable that air-conditioned room must be closed, as a result, indoor micro-
Dirt, smog, bacterium, virus, exhaust gas are continuously increased, and oxygen content constantly reduces, and air quality is worse and worse.In recent years, with
" air conditioner disease " has attracted increasing attention, and having begun requirement don't stay in air-conditioned room for a long time, and pass through
The logical fresh air that opens a window either mends fresh air to room in such a way that indoor exhaust wind forms negative pressure by door, window gap leakage, improves room
Interior environment.There are mainly two types of the modes for being applied to new and old air exchange currently on the market:
One, indoor air is arranged to outdoor by single fan, makes indoor formation negative pressuren zone, force outdoor fresh air from
The gap in room flows into indoor；
Two, outdoor fresh air is directly drawn into interior；
All there is energy loss in both above modes, because of the direct suction of outdoor hot and cold air, Shi Biyin
The variation for playing former room temperature, causes a large amount of energy loss, increases the energy loss of air conditioner, reduce air conditioner refrigeration,
Heating effect.Especially in winter, the input of outdoor cold air even will cause the generation of air-conditioning dew condensation phenomenon；
In addition, both the above mode has that pollute air enters the room without filtering, when outdoor is serious mist
When haze weather, outdoor air is directly extracted, indoor more serious pollution will be caused.

Dress portion, is again introduced into fresh air channel, carries out coarse filtration by first filter 22, filters out dust, removes peculiar smell, prevents dust
Equal particulate matters, which enter heat exchanging core 40, causes heat exchanging core 40 to block, using third filter 24, along fresh air channel
Into heat exchanging core, by third filter 24, fresh air outlet 312 is passed through by centrifugation blade again.
Three, outdoor: the first driving motor 53, the second driving motor 54 driving fresh air deflector 51 is individually discharged in room air
It is located at third working condition with waste air deflector 52, fresh air deflector 51 is located at closed position, and room air is by waste air import 321
Into air duct, mounting portion is reached along air duct, outdoor is discharged to by fresh air outlet 312.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
Aeration device 20 may be implemented in three kinds of working conditions by setting retaining device 50 in air conditioner indoor unit of the invention
In conversion, when retaining device 50 is in the first working condition, room air is successively after waste air channel 32, fresh air channel 31
It returns indoor；When retaining device 50 is in the second working condition, fresh inlet 311 and waste air outlet 322 are fully open, outdoor empty
Gas is entered after fresh air channel by fresh inlet 311 flows into interior, and room air is returned after passing through waste air channel 32 by waste air outlet 322
Go back to outdoor；When retaining device 50 is in third working condition, room air is flowed into after passing through waste air channel 32 by waste air outlet 322
It is outdoor.Such setting can make aeration device convert different working conditions under different indoor environments, to improve Interior Space
Makings amount meets the needs of user, improves comfort level.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
