Between when moving, cleaning module 150 and the vertical range relative close on the surface of indoor heat exchanger 160.Thus, when cleaning module 150
It is moved to when blocking certain a part of indoor heat exchanger 160, relatively large windage can be produced in the regional area, the part is influenceed
The heat exchange efficiency in region.So that indoor heat exchanger 160 produces local temperature difference, the problems such as easily occurring condensation or freeze makes
Its exchange capability of heat weakens.
Fig. 7 is the indoor heat exchanger 160 and blower fan of wall-hanging air conditioner indoor unit 100 according to an embodiment of the invention
170 schematic diagram.
To solve the above problems, in some alternative embodiments of the present invention, indoor heat exchanger 160 has multiple heat transfer zones
Domain and at least one electric expansion valve 161, and it is configured to opening according to the position adjustments electric expansion valve 161 of cleaning module 150
Spend to control the coolant quantity into multiple heat exchange areas.
Electric expansion valve 161 can be multiple.The particular number of electric expansion valve 161 can be with heat exchange area quantity phase
Together, so that each heat exchange area is respectively provided with an electric expansion valve 161 on the other side, so as to by corresponding thereto
Electric expansion valve 161 directly adjust control enter its in refrigerant input quantity so that adapt to each heat exchange area due to windage not
Heat exchange efficiency that is same and producing difference, and then make it that the heat transfer effect of the regional of indoor heat exchanger 160 is roughly the same.
The quantity of multiple heat exchange areas is two, respectively positioned at the lower section of air inlet 121 the first heat exchange area and be located at
The second heat exchange area (i.e. corresponding region on the inside of front panel) below the front side in the forward position of air inlet 121；
Cleaning module 150 by drive device 140 driving be moved to the inner side of air inlet 121 when, cleaning module 150 cover into
Air port, now the location of cleaning module 150 is first position, and the downstream in the air intake path of air inlet 121 is first to change
Thermal region.
When cleaning module 150 is moved to the inner side of front panel 110 by the driving of drive device 140, air inlet 121 is appeared.
Now, the position of cleaning module 150 is the second place.The corresponding region in inner side of front panel 110 is the second heat exchange area.
Indoor heat exchanger 160 can have for total diversion pipeline 200 of guiding refrigerant inflow and for respectively to first
Heat exchange area and the second heat exchange area convey the first diversion pipeline 210 and the second diversion pipeline 220 of refrigerant.Electric expansion valve
161 may be disposed at the input of the first diversion pipeline 210 or the second diversion pipeline 220, enter the first diversion pipeline 210 to adjust
And/or second diversion pipeline 220 coolant quantity.
When cleaning module 150 is moved to the inner side of air inlet 121 by the driving of drive device 140, cleaning module is completely obscured
The position of air inlet 121, with the air wind purifying to the machine of getting in 100.Now, positioned at the inner side of cleaning module 150, air intake
First heat exchange area of the lower section of mouth 121 is influenceed more obvious by the windage of cleaning module 150.Thus, it is desirable to limit inflow
The refrigerant of one heat exchange area, and/or increase flow into the refrigerant of the second heat exchange area.
When indoor air quality is slightly good, and user does not require that the cleaning module of indoor set 100 starts purification pattern, only
Change module 150 to be driven by the position movement of the inner side of position front panel 110 of completely obscured air inlet 121 by drive device 140,
Not with the position of surrounding air bump contact, to reduce or avoid and air contact as far as possible.Now, positioned at cleaning module 150
Rear side, the second heat exchange area for being approximately perpendicular to the place plane of air inlet 121 are influenceed more bright by the windage of cleaning module 150
It is aobvious.Thus, it is desirable to the refrigerant for flowing into the second heat exchange area is limited, and/or increase flows into the refrigerant of the first heat exchange area.
It that is to say, according to the different shift positions of cleaning module 150, indoor heat exchanger 160 can correspondingly mark off difference
Heat exchange area.Further, when the position of cleaning module 150 changes, indoor set 100 can be immediately by directly adjusting
The refrigerant input quantity of each heat exchange area, so that the heat transfer effect for promptly making heat exchanger 160 overall is equalized, it is to avoid heat exchange
There is the excessive phenomenon of local temperature difference in device 160.
In some optional embodiments, the quantity of electric expansion valve 161 can be one.The electric expansion valve 161 can
The input of the second diversion pipeline 220 is arranged on, and is configured to be moved to screening when cleaning module 150 is driven by drive device 140
When covering the position of air inlet 121, electric expansion valve 161 increases its aperture to the first aperture.It that is to say, when cleaning module 150
In the inner side of air inlet 121 and when covering air inlet 121, the air-flow that its windage passes through the first heat exchange area is reduced, and then
Reduce the refrigerant heat exchange amount in the first heat exchange area.Now, electric expansion valve 161 can increase its aperture, so as to flow into the
The refrigerant of two heat exchange areas increases, and the refrigerant for flowing into the first heat exchange area is reduced.As a result, the first heat exchange area and second is changed
The heat exchange pressure and heat exchange efficiency of thermal region are adapted with flowing through its air quantity so that the heat transfer effect both it is equalized.
Correspondingly, when cleaning module 150 is moved to the position of the inner side of front panel 110 by drive device 140, electronics is swollen
Swollen valve 161 reduces its aperture to the second aperture for being less than the first aperture.It that is to say, the cleaning module 150 positioned at the second place
The air-flow that windage passes through the second heat exchange area is reduced, and then reduces the refrigerant heat exchange amount in the second heat exchange area.Now,
Electric expansion valve 161 can reduce its aperture, so that the refrigerant for flowing into the second heat exchange area is reduced, flow into the first heat exchange area
Refrigerant increases.As a result, the heat transfer effect of the first heat exchange area and the second heat exchange area is equalized.
Specifically, because the first heat exchange area positioned at the lower section of air inlet 121 is compared to the on front side of casing interior
Two heat exchange areas are easier to touch more surrounding air, and heat exchange efficiency is of a relatively high.Therefore, can be by electric expansion valve 161
It is set directly at the input for the second diversion pipeline 220 that refrigerant is conveyed for the second heat exchange area, enters so as to limitation in advance
The refrigerant input quantity of second heat exchange area, to prevent or suitably limit the issuable heat transfer effect of heat exchanger 160 unbalanced.
In some alternative embodiments, the number of the heat exchange area of heat exchanger 160 can also be other numbers more than two
Value.Correspondingly, the shift position of cleaning module 150 also can further be segmented.In the present embodiment, cleaning module 150 is multiple
Shift position can correspond to the preferable refrigerant input quantity of multigroup each heat exchange area respectively.It that is to say, be likely to occur for heat exchanger 160
The uneven situation of a variety of heat exchange efficiencies, corresponding refrigerant input quantity shunt ratio is set respectively, so that heat exchanging device 160 is each
The regulation of refrigerant input quantity is more accurate rapid in branch line.
The present embodiment is by the way that electric expansion valve 161 to be arranged on to the input of the second diversion pipeline 220 of the second heat exchange area
End so that when the position of cleaning module 150 changes, it is only necessary to which electric expansion valve 161 changes a relatively small aperture difference and is
It may be such that the heat exchange pressure of two heat exchange areas is equalized, so as to improve the governing speed of electric expansion valve 161, and cause
The amplitude of accommodation of electric expansion valve 161 is more gently stablized, and extends its service life.
Further, the concrete numerical value of the first aperture and the second aperture can be set according to the actual use situation of indoor set.
In some embodiments of the invention, the first aperture can be any opening degree value between 70~80%.For example can for 70%,
72%th, 74%, 76%, 78% or 80% etc..Second aperture can be any opening degree value between 15~50%, for example, can be
15%th, 20%, 25%, 30%, 35%, 40%, 45% or 50% etc..
In some embodiments of the invention, heat exchanger 160 have three-stage housing, housing include be horizontally set on into
First heat exchanging segment 301 of the lower section of air port 121, the second heat exchanging segment 302 from the side-lower extension forward of the front end of the first heat exchanging segment 301
And the 3rd heat exchanging segment 303 extended vertically downwards from the lower end of the second heat exchanging segment 302.First diversion pipeline 210 and second is led
Flow tube road 220 is each configured to access case from the second heat exchanging segment 302.
It that is to say, the input of the first diversion pipeline 210 and the second diversion pipeline 220 can be along same bearing of trend access digit
In the second heat exchanging segment 302 of the middle section position of heat exchanger 160.So that refrigerant intake line mechanism is compact, take up space small.Enter
One step, the pipeline being located inside the second heat exchanging segment 302 of the first diversion pipeline 210 and the second diversion pipeline 220 is respectively along phase
Opposite direction extends, so as to avoid the refrigerant in two respective distribution pipelines in heat exchange area from influencing each other.
In some embodiments of the invention, the first heat exchanging segment 301 and at least partly the second heat exchanging segment 302 formation first are changed
Thermal region.Second heat exchange area of 3rd heat exchanging segment 303 and the formation of at least partly the second heat exchanging segment 302.First diversion pipeline 210 exists
Bending extends upwardly to the first heat exchanging segment 301 in second heat exchanging segment 302, to cover all the first heat exchange areas.Second mozzle
The bending in the second heat exchanging segment 302 of road 220 extends downward into the 3rd heat exchanging segment 303, to cover all the second heat exchange areas.
It that is to say, the top half of the second heat exchanging segment 302 belongs to the first heat exchange area, the lower half of the second heat exchanging segment 302
Belong to the second heat exchange area.Thus, when cleaning module 150 is located between first position and the second place, its heat exchanging device
The 160 main influences produced are substantially all positioned at the where the input of the first diversion pipeline 210 and the second diversion pipeline 220
On two heat exchanging segments 302.So that the windage of cleaning module 150 is imitated for the heat exchange of the first heat exchange area and the second heat exchange area
The influence of fruit is more similar.Thus, the input of the first diversion pipeline 210 and the second diversion pipeline 220 is arranged at heat exchange
The middle section position of device 160, can both reduce the amplitude of accommodation of the aperture of electric expansion valve 161, and it can be reduced again and adjusts number of times so that is changed
The operation of hot device 160 is more stablized.
In some embodiments of the invention, it is respectively arranged with the outer surface of the first heat exchange area and the second heat exchange area
First temperature sensor and second temperature sensor (not shown), to detect the first surface temperature of the first heat exchange area respectively
Degree and the second surface temperature of the second heat exchange area.Further, electric expansion valve 161 can be configured to when first surface temperature and
When the difference of second surface temperature is more than a default temperature gap, electric expansion valve 161 increases or reduced a default aperture
Value.
It that is to say, the aperture of electric expansion valve 161 can carry out instant tune according to the shift position of cleaning module 150 first
Save (increase to the first aperture or be decreased to the second aperture).Then, among the process that heat exchanger 160 is run, electric expansion valve
161 can also in real time be adjusted according to the first surface temperature and second surface temperature of the first heat exchange area and the second heat exchange area
It is whole, so that the heat transfer effect in each region of heat exchanger 160 persistently maintains roughly the same level, it is ensured that the use of user
Effect.
Specifically, the temperature gap of first surface temperature and second surface temperature can be according to heat exchanger 160 performance, room
Purification pattern of interior machine etc. is further set.In some embodiments of the invention, the temperature gap can be 0.5~2 DEG C
Between arbitrary temp value.Such as can be 0.5 DEG C, 0.7 DEG C, 0.9 DEG C, 1 DEG C, 1.5 DEG C, 2 DEG C.In some preferred embodiments
In, the temperature gap can be preferably 1 DEG C, will not have big difference with each area surface temperature for ensureing heat exchanger 160, and can keep away
The regulation for exempting from the aperture of electric expansion valve 161 is excessively frequent.
In some embodiments of the invention, it is more than temperature gap in the difference of first surface temperature and second surface temperature
In the case of, electric expansion valve 161 is configured to：When first surface temperature is less than second surface temperature, electric expansion valve 161 increases
Big opening value.When first surface temperature is more than second surface temperature, electric expansion valve 161 reduces opening value.Specifically, preset
Aperture regulation value can be 1~10% between arbitrary value.For example can for 1%, 2%, 3%, 4%, 5%, 6%, 7%,
8%th, 9% or 10% etc..
It that is to say, when the aperture of electric expansion valve 161 according to the shift position of cleaning module 150 has carried out first regulation
Afterwards, in the course of work of heat exchanger 160, the heat transfer effect of the first heat exchange area and the second heat exchange area may be by air conditioning chamber
There is less difference in the influence of the factor such as indoor environment residing for interior wall hanging machine, so as to cause heat exchanger surface temperature unbalanced.
Now, according to the surface temperature difference of each heat exchange area of heat exchanger 160, the aperture of electric expansion valve 161 is adjusted more by a small margin,
It can realize that refrigerant input quantity carries out real-time monitoring, the rapid local temperature difference eliminated on heat exchanger 160 in heat exchanging device 160.It is special
Not, the default opening value needed for when this fine setting can also be for first regulations such as the first aperture of optimization, the second apertures provides number
According to support, pole contributes to the perfect in shape and function of air-conditioner indoor wall on-hook.
In some real-time examples of the present invention, indoor apparatus of air conditioner also includes a point liquid adjusting means 70, is arranged at total mozzle
The upstream of the downstream on road 200, the first diversion pipeline 210 and the second diversion pipeline 220.
Fig. 8 is the schematic elevational view of according to an embodiment of the invention point of liquid adjusting means 70.Fig. 9 is according to this hair
The schematic cross sectional views of point liquid adjusting means 70 of bright one embodiment.
Referring to Fig. 8, point liquid adjusting means 70, which has in branch chamber, branch chamber, is provided with an elastic component 700 with by inside it
Space is divided into the first sub-chamber and the second sub-chamber, to accommodate the refrigerant at least partly flowing into branch chamber respectively.Specifically, liquid is divided
Adjusting means 70 also includes total diversion pipeline 200, the first diversion pipeline 210 and the second mozzle connected with its refrigerant input port
Road 220.Total diversion pipeline 200 is configured to guiding refrigerant and enters branch chamber.First diversion pipeline 210 is configured to and the first sub-chamber
Connection, to guide the refrigerant in the first sub-chamber to flow out a point liquid adjusting means 70.Second diversion pipeline 220 is configured to and the second son
Chamber, to guide the refrigerant in the second sub-chamber to flow out a point liquid adjusting means 70.
Further, the first diversion pipeline 210 is configured to connect with the refrigerant receiving port of the first heat exchange area, to guide
Refrigerant in one sub-chamber enters the first heat exchange area.Second diversion pipeline 220 is configured to connect with the refrigerant of the second heat exchange area
Close up and connect, to guide the refrigerant in the second sub-chamber to enter the second heat exchange area.
In some embodiments of the invention, elastic component 700 is made up of fixed part 710 and movable part 720.Fixed part 710
It is curved, and be configured to its outer circumferential side ora terminalis and be fixed on the inwall of branch chamber.Movable part 720 is configured to its part the week side of boss ora terminalis
It is connected with least part inner circumferential side ora terminalis of fixed part 710, at least part of all lateral edges of its another part and fixed part 710
The week side of boss ora terminalis and/or the internal partial wall adjoining with branch chamber, the refrigerant in the first sub-chamber and the second sub-chamber is separated,
And its interior refrigerant is delivered in the refrigerant pipeline of two heat exchange areas respectively.
Referring to Fig. 9, in some embodiments of the invention, elastic component 700 can be sheet.Fixed part 710 and movable part
720 can be collectively forming a complete cross sectional shape, and the cross sectional shape has at least one section identical shape with branch chamber
Shape and size, two parts are divided into by its inner space.
It that is to say, when the refrigeration of two heat exchange areas is similar, the heat exchange pressure of the two is also more balanced, so that
The first sub-chamber and second sub-chamber's fluid pressure that must be connected respectively with two heat exchange areas are roughly equal.Thus, when
When pressure in one sub-chamber and the second sub-chamber is equal, elastic component 700 will not be by perpendicular active force, or the effect
Power is much smaller than the screen resilience of its own, so that avoid producing gap between movable part 720 and fixed part 710 or shunting cavity wall,
And then prevent in the first sub-chamber and the second sub-chamber produce fluid communication so that two heat exchange areas be able to maintain that it is current compared with
For heat transfer effect in a balanced way, it is to avoid it the appearance of the excessive situation of local temperature difference occurs, the stability of heat exchanger operation is enhanced.
Further, the part (hereinafter referred to as connecting portion) being connected with shunting cavity wall of fixed part 710 is relative to work
Dynamic portion 720 it is (following with least part inner circumferential side ora terminalis of fixed part 710 and/or the part adjacent with the inwall of branch chamber
Abbreviation adjacency section) input port away from branch chamber reception refrigerant.
Thus, when the pressure in the first sub-chamber and the second sub-chamber is unequal, the first sub-chamber and the second sub-chamber
Pressure difference can cause flexure strip by perpendicular active force.When the active force is more than the screen resilience of elastic component 700 itself,
Gap is produced between movable part 720 and shunting cavity wall, the first sub-chamber and the second sub-chamber are interconnected, and produce fluid friendship
Change to adjust the amount of the refrigerant respectively enterd in the first sub-chamber and the second sub-chamber.
When cleaning module is purifying mobile handoff between position and non-purification position, it is produced to two heat exchange areas
Windage is different, and then causes the heat exchange efficiency of two heat exchange areas difference occur.
Specifically, when cleaning module 150 is located at the air intake path upstream of the first heat exchange area connected with the first sub-chamber
When, the windage increase of first heat exchange area, heat exchange efficiency reduction, its interior refrigerant temperature is gradually less than in the second heat exchange area
Refrigerant temperature so that the first heat exchange area fluid pressure gradually be less than the second heat exchange area in Fluid pressure.
Correspondingly, the Fluid pressure in the first sub-chamber connected with the first heat exchange area is gradually less than and the second heat transfer zone
Fluid pressure in second sub-chamber of domain connection.When the active force that the fluid pressure differential of Liang Ge sub-chamber is produced is more than elastic component
During 700 itself screen resilience, one end stress positioned at adjacency section of movable part is bent to the first small sub-chamber of Fluid pressure, from
And make it that cross-sectional area of first sub-chamber at the refrigerant input port of branch chamber reduces, and cause close point of the second sub-chamber
Flow the cross-sectional area increase at the refrigerant input port of chamber.Thus, the bootable relatively more refrigerants of the movable part 720 of bending are flowed into
Second sub-chamber, and the coolant quantity flowed into the first sub-chamber is limited, so that the first heat exchange connected with the first sub-chamber
The temperature difference and heat exchange pressure differential of region and the second heat exchange area connected with the second sub-chamber are gradually reduced, until the first sub- chamber
Active force produced by the pressure differential of room and the second sub-chamber is less than the screen resilience of elastic component 700.
The indoor apparatus of air conditioner of the present invention by setting point liquid adjusting means 70 of flexible part 700 to carry out coolant distribution,
So that when the heat transfer effect of each heat exchange area of heat exchanger produces more apparent difference, the elastic component 700 can be poor in heat transfer effect
In the presence of point sap cavity internal pressure differences caused by different, the amount into the refrigerant of each heat exchange area is automatically regulated, without volume
Outer detection or supervising device, so as to simplify the structure of indoor apparatus of air conditioner, reduce its manufacturing cost.
In the air conditioner room unit of the present invention, cleaning module is driven the air intake in completely obscured indoor set by drive device
Moved between the purification position of mouth and the default location for leaving air inlet, when being not turned on purification function, cleaning module, which is located at, to be moved
Go out air inlet and reach non-purification position；After purification function is opened, cleaning module is driven by drive device, is moved to completely obscured
The purification position of the air inlet of indoor set, is purified to the air-flow for the machine of getting in.
Because above-mentioned cleaning module is when purifying position and non-purification position, the windage that indoor set blower fan produces air-flow is obvious
Difference, after purification pattern is entered, air-flow necessarily causes the heat transfer effect decay by indoor set heat exchanger, held by filtering
Easily there is high load capacity problem, can accordingly be controlled according to the operational mode of air conditioner, make air conditioner reduction pair in purification
The normal refrigeration of air conditioner or the influence of heat-production functions.
For example after purification pattern is entered, the target tube temperature of the Tube Sheet of Heat Exchanger temperature of indoor set can be set, and detect in real time
The Tube Sheet of Heat Exchanger temperature of indoor set, feedback control is carried out according to the temperature difference of detection pipe temperature and target tube temperature to the refrigeration system of air conditioner
System.The air conditioner that the indoor set of the present invention is applicable also includes outdoor unit, and above-mentioned refrigeration system may include the heat exchange in indoor set

In air conditioner refrigerating operaton, if Tube Sheet of Heat Exchanger temperature is no more than the first temperature difference threshold less than target tube temperature after cleaning
When being worth (such as 3 degree), feedback control can be carried out to the blower fan of indoor set according to difference, Tube Sheet of Heat Exchanger temperature temperature is lower, indoor
The rotation speed of fan of machine is faster.If the lifting of indoor set rotation speed of fan is it cannot be guaranteed that Tube Sheet of Heat Exchanger temperature is maintained and target tube Wen Wen
Difference is when within the first temperature difference threshold, then the aperture of the throttling arrangement of kind of refrigeration cycle is compressed in increase, if still it cannot be guaranteed that heat exchange
Device Guan Wen is maintained with the target tube temperature temperature difference when within the second temperature difference threshold, then frequency reducing is carried out to compressor, so as to prevent room
Interior machine heat exchanger temperature is too low and high load capacity occurs.
When air conditioner carries out heating operation, if Tube Sheet of Heat Exchanger temperature is warm no more than first higher than target tube temperature after cleaning
During poor threshold value (such as 3 degree), feedback control can be carried out to the blower fan of indoor set according to difference, Tube Sheet of Heat Exchanger temperature temperature is higher,
The rotation speed of fan of indoor set is faster.If the lifting of indoor set rotation speed of fan is it cannot be guaranteed that Tube Sheet of Heat Exchanger temperature is maintained and target tube
The temperature difference when within the first temperature difference threshold, then increase compression kind of refrigeration cycle throttling arrangement aperture, if still it cannot be guaranteed that
Tube Sheet of Heat Exchanger temperature is maintained with the target tube temperature temperature difference when within the second temperature difference threshold, then carries out frequency reducing to compressor, so that anti-
Only indoor set heat exchanger temperature is too high and high load capacity occur.
Above-mentioned first temperature difference threshold and the second temperature difference threshold can enter according to the specification and use requirement of indoor set heat exchanger
Row configuration, for example, set positive and negative 3 degrees Celsius by the first temperature difference threshold, the second temperature difference threshold be set into positive and negative 5 degrees Celsius.
