Specific embodiment
To keep the embodiment of the present invention, technical solution and advantage more obvious, below in conjunction with attached drawing to skill of the invention
Art scheme carries out clear, complete description, it is clear that and the embodiment described is a part of the embodiments of the present invention, rather than all
Embodiment.It will be apparent to a skilled person that these embodiments are used only for explaining technical principle of the invention, and
It is not intended to be limiting protection scope of the present invention.
Air conditioner of the invention includes indoor unit, fresh air pipeline, exhaust pipeline and fresh-air fan is provided on indoor unit, newly
When wind blower rotates forward, outdoor wind enters interior along fresh air pipeline；When fresh-air fan inverts, indoor wind is arranged along exhaust pipeline
Outdoor is arrived out, and the dust on heat exchanger can be sucked into outdoor during wind indoors discharges.
As an example, referring to Fig.1, Fig. 1 is a kind of structural schematic diagram of embodiment of the air condition of that present invention.Such as Fig. 1
Shown, in this embodiment, air conditioner includes indoor unit 1, and fresh air pipeline 11, exhaust pipeline 12 and new are provided on indoor unit 1
Wind blower 13, fresh air pipeline 11 and exhaust pipeline 12 are mutually independent two root canal road；When fresh-air fan 13 rotates forward, outdoor wind
Interior is entered along fresh air pipeline 11；When fresh-air fan 12 inverts, indoor wind is discharged to outdoor along exhaust pipeline 12, and
Dust on heat exchanger 2 can be sucked into outdoor during discharging by indoor wind.
As another example, referring to Fig. 2, Fig. 2 is the structural schematic diagram of another embodiment of the air condition of that present invention.Such as
Shown in Fig. 2, in this embodiment, fresh air pipeline 11 and exhaust pipeline 12 after one end far from indoor unit crosses with main line 10
Connection；When fresh-air fan 13 rotates forward, outdoor wind successively enters interior along main line 10, fresh air pipeline 11；Fresh-air fan 13
When reversion, indoor wind is successively discharged to outdoor along exhaust pipeline 12, main line 10, and the mistake that wind indoors discharges
The dust on heat exchanger 2 can be sucked into outdoor in journey.
The difference of both the above embodiment is only that the set-up mode of exhaust pipeline 12, and the exhaust pipeline 12 of embodiment one is
Independently of a root canal road of fresh air pipeline 11, more than 12 fresh air pipeline 11 of exhaust pipeline of embodiment two is connected to main line after crossing
10。
Further, cleaning module is provided with (in figure with continued reference to Fig. 1 and Fig. 2, fresh air pipeline 11 and 1 junction of indoor unit
It is not shown), the cleaning module is for purifying wind from the outside into the room.When fresh-air fan 13 inverts, fresh wind tube
Road 11 is at closed state.It can prevent the dust on heat exchanger 2 from entering fresh air pipeline in this way and then pollute cleaning module.
Preferably, air conditioner of the invention further includes Air Blast fan 14, and fresh air pipeline 11 and exhaust pipeline 12 are set to room
The first side (left side in Fig. 1 and Fig. 2) of interior machine 1, Air Blast fan 14 are set to second side opposite with the first side (Fig. 1 and Fig. 2
In right side), Air Blast fan 14 start after the dust on heat exchanger 2 can be blown afloat.So, when fresh-air fan 13 inverts
When, Air Blast fan 14 can be started simultaneously, to assist the dust collection efficiency of the raising heat exchanging device 2 of fresh-air fan 13.
In a kind of specific embodiment, referring to Fig.1, air conditioner of the invention further includes condensate line 3, indoor unit
Heat exchanger generate condensed water by condensate line 3 discharge.Preferably, water quality can also be set on condensate line 3
Turbidity transducer 31, for detecting the condensation water turbidity in condensate line 3.
Fresh air system about air conditioner, it is possible to understand that for a set of independent sky being made of supply air system and exhaust system
Gas processing system, its working principle is that send fresh air to interior with special equipment according in closed indoor side, then from the other side
From special equipment to outdoor discharge, " fresh air field of flow " will form indoors, to meet the needs of indoor fresh air ventilating.This hair
Bright is to be further improved on the basis of fresh air system to fresh air pipeline, that is, increases a row independently of fresh air pipeline
Air pipe line is no longer described in detail herein about specific fresh air system and its working principle.
Based on above-mentioned air conditioner structure, the invention also provides a kind of air conditioner automatically cleaning control methods.Reference Fig. 3,
Fig. 3 is the broad flow diagram of air conditioner automatically cleaning control method of the invention.As shown in figure 3, air conditioner automatically cleaning of the invention
The dirty degree that control method includes the following steps: S110, obtains heat exchanger；S120, judged whether to make fresh air wind according to dirty degree
Machine reversion.Specifically, inverting fresh-air fan when the dirty degree of heat exchanger exceeds preset standard value.That is, this hair
When the heat exchanger of bright machine indoors needs to carry out dust suction, the dust of heat exchanger is inhaled by fresh air pipeline using fresh-air fan reversion
Outdoor is arrived out, to realize the cleaning to indoor unit.The preset standard value can be by those skilled in the art according to the actual situation
Setting, it is intended to for judging the dirty net degree of heat exchanger, i.e., when dirt degree is below the preset standard value, illustrate not needing to exchange
Hot device carries out dust suction, when dirty degree is more than preset standard value, illustrates that heat exchanger is dirtier, that is, needs heat exchanging device dust suction.
Further, air conditioner automatically cleaning control method of the invention further include: in fresh-air fan reversion, make fresh air pipeline
In closed state.It can prevent the dust on heat exchanger from entering fresh air pipeline in this way and then pollute cleaning module.Further, originally
The air conditioner automatically cleaning control method of invention further include: before or while inverting fresh-air fan, start Air Blast fan, thus
Fresh-air fan is assisted to improve the dust collection efficiency of heat exchanging device.
As an example, in step s 110, i.e. the dirt of acquisition heat exchanger can also be as follows when spending: indoors
In the case of heat exchanger generates condensed water, the turbidity of the condensed water in condensate line is detected；Judged according to the turbidity of condensed water
The turbidity of heat exchanger.Specifically, the condensed water generated in cooling mode can also compare if indoor heat exchanger is messy
Dirtier, i.e., the turbidity of condensed water can also change with the dirty net degree of indoor heat exchanger.It therefore, can according to the turbidity of condensed water
Accurately to judge the turbidity of indoor heat exchanger, and then judge whether that heat exchanging device is needed to carry out dust suction cleaning.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
