It is provided with air-inlet grille, air-inlet grille and is formed with air inlet 121 to allow surrounding air to enter the indoor apparatus of air conditioner.Skeleton
110th, case 120 and front panel 130 can collectively form the casing of indoor apparatus of air conditioner.Further, indoor apparatus of air conditioner also includes net
Change purification assembly 150.Purification assembly 150 is configured to that controlled movement and air inlet 121 can be covered, with to entering via air inlet 121
The air for entering casing is purified.Heat exchanger 160 may be disposed at the inner side of purification assembly 150, and be configured to and flow through its air
Heat exchange is carried out, to form the heat exchange air that the temperature of cleaning changes.
Especially, the heat exchanger 160 of indoor apparatus of air conditioner of the present invention has multiple heat exchange areas and at least one electronic expansion
Valve 161.Heat exchanger 160 is configured to many to control to enter according to the aperture of the position adjustments electric expansion valve 161 of purification assembly 150
The refrigerant input quantity of individual heat exchange area.
Specifically, when purification assembly 150 is moved in casing, purification assembly 150 it is vertical with the surface of heat exchanger 160 away from
From relative close.Thus, when purification assembly 150, which is moved to, blocks certain a part of heat exchanger 160, it can be produced in the regional area
Relatively large windage, influences the heat exchange efficiency of the regional area.So that heat exchanger 160 produces local temperature difference, easily send out
The problems such as giving birth to condensation or freeze, weakens its exchange capability of heat.
Those skilled in the art are generally by making the reduction of the overall frequency of heat exchanger 160 come the gentle effect that exchanges heat before making the present invention
The problem of rate is uneven.However, this is to sacrifice the refrigerating capacity of indoor apparatus of air conditioner as cost, the use effect of user is had a strong impact on
Really.
160 points creatively by heat exchanger of the present invention is multiple heat exchange areas, and for flowing through the wind of multiple heat exchange areas
The difference of amount, adjusts the refrigerant input quantity in each heat exchange area.So as to ensure indoor apparatus of air conditioner integrally with higher heat exchange
While efficiency, it is to avoid the appearance of the excessive situation of local temperature difference occurs in heat exchanger 160, the stabilization of the operation of heat exchanger 160 is enhanced
Property, provide the user more preferable usage experience.
In some embodiments of the invention, electric expansion valve 161 can be multiple.The specific number of electric expansion valve 161
Amount can be identical with the quantity of heat exchange area, so that each heat exchange area is respectively provided with an electric expansion valve 161 on the other side,
So as to directly adjust the refrigerant input quantity that control enters in it by electric expansion valve 161 corresponding thereto, so that suitable
That answers each heat exchange area produces the heat exchange efficiency of difference due to windage difference, and then causes the heat exchange effect of heat exchanger regional
It is really roughly the same.
Fig. 2 is the schematic diagram of heat exchanger 160 according to an embodiment of the invention.Referring to Fig. 2, the present invention's
In some embodiments, the quantity of multiple heat exchange areas can be two.Two heat exchange areas are respectively to be located at the lower section of air inlet 121
The first heat exchange area and the second heat exchange area below the front side in the forward position of air inlet 121.Further, purification assembly
150 can be configured to and controlled can be moved to the first position of the air intake path upstream positioned at the first heat exchange area to cover air inlet
121.Correspondingly, purification assembly 150 controlled can also be moved to the second place of the air intake path upstream positioned at the second heat exchange area
To open air inlet 121.
Especially, heat exchanger 160 can have for the main pipe rail 200 of guiding refrigerant inflow and for being changed respectively to first
Thermal region and the second heat exchange area convey the first distribution pipeline 210 and the second distribution pipeline 220 of refrigerant.Electric expansion valve 161
May be disposed at the input of the first distribution pipeline 210 or the second distribution pipeline 220, with adjust enter the first distribution pipeline 210 and/
Or second distribution pipeline 220 coolant quantity.
Specifically, purification assembly 150 has two main shift positions.One is located at the lower section of air inlet 121, works as user
Need indoor apparatus of air conditioner to enter its in air purify when, purification assembly 150 internal side of shell covering air inlet 121 with
At least part air for entering indoor apparatus of air conditioner is purified.Now, positioned at the inner side of purification assembly 150, the lower section of air inlet 121
The first heat exchange area influenceed more obvious by the windage of purification assembly 150.Thus, it is desirable to limit the first heat exchange area of inflow
Refrigerant, and/or increase flow into the second heat exchange area refrigerant.Another operating position of purification assembly 150 is before air inlet 121
Below the front side on edge, the inner side of front panel 130 that is to say.When indoor air quality is slightly good, user does not require indoor apparatus of air conditioner
When starting purification function, purification assembly 150 controlled can be moved to inner front side in machine, position not with surrounding air bump contact
Put, to reduce or avoid and air contact as far as possible.Now, positioned at the rear side of purification assembly 150, be approximately perpendicular to the institute of air inlet 121
Influenceed more obvious by the windage of purification assembly 150 in the second heat exchange area of plane.Changed thus, it is desirable to limit inflow second
The refrigerant of thermal region, and/or increase flow into the refrigerant of the first heat exchange area.
It that is to say, according to the different shift positions of purification assembly 150, heat exchanger 160 can correspondingly mark off different change
Thermal region.Further, when the position of purification assembly 150 changes, indoor apparatus of air conditioner can be each by directly adjusting immediately
The refrigerant input quantity of individual heat exchange area, so that the heat transfer effect for promptly making heat exchanger 160 overall is equalized, it is to avoid heat exchanger
160 there is the excessive phenomenon of local temperature difference.In some embodiments of the invention, the quantity of electric expansion valve 161 can be one
It is individual.The electric expansion valve 161 may be provided at the input of the second distribution pipeline 220, and be configured to move when purification assembly 150 is controlled
When moving to first position, electric expansion valve 161 increases its aperture to the first aperture.It that is to say, when purification assembly 150 is located at first
During position, the air-flow that its windage passes through the first heat exchange area is reduced, and then makes the refrigerant heat exchange amount in the first heat exchange area
Reduce.Now, electric expansion valve 161 can increase its aperture, so that the refrigerant for flowing into the second heat exchange area increases, flow into first
The refrigerant of heat exchange area is reduced.As a result, the heat exchange pressure and heat exchange efficiency of the first heat exchange area and the second heat exchange area with
Flow through its air quantity to be adapted so that the heat transfer effect both it is equalized.
Correspondingly, when purification assembly 150 is controlled is moved to the second place, electric expansion valve 161 reduces its aperture to small
In the second aperture of the first aperture.It that is to say, the windage positioned at the purification assembly 150 of the second place passes through the second heat transfer zone
The air-flow in domain is reduced, and then reduces the refrigerant heat exchange amount in the second heat exchange area.Now, electric expansion valve 161 can be opened
Degree reduces, so that the refrigerant for flowing into the second heat exchange area is reduced, the refrigerant for flowing into the first heat exchange area increases.As a result, the
The heat transfer effect of one 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 internal
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 distribution 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 other embodiments of the present invention, the number of the heat exchange area of heat exchanger 160 can also be more than two
Other numerical value.Correspondingly, the shift position of purification assembly 150 also can further be segmented.In the present embodiment, purification assembly 150
Multiple shift positions can correspond to the preferable refrigerant input quantity of multigroup each heat exchange area respectively.It that is to say, can for heat exchanger 160
The situation for a variety of heat exchange efficiencies inequality that can occur, sets corresponding refrigerant input quantity shunt ratio, so that heat exchanging device respectively
The regulation of refrigerant input quantity is more accurate rapid in 160 each branch line.The present invention is by the way that electric expansion valve 161 is arranged on
The input of second distribution pipeline 220 of the second heat exchange area on front side of casing internal so that when the position of purification assembly 150
When putting change, it is only necessary to which it is that may be such that the heat exchange of two heat exchange areas that electric expansion valve 161, which changes a relatively small aperture difference,
Pressure is equalized, so as to improve the governing speed of electric expansion valve 161, and causes the amplitude of accommodation of electric expansion valve 161
It is gentler stable, extend 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 apparatus of air conditioner
Put.In some embodiments of the invention, the first aperture can be any opening degree value between 70~80%.For example can be
70%th, 72%, 74%, 76%, 78% or 80% etc..Second aperture can be any opening degree value between 15~50%, for example
Can be 15%, 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 distribution pipeline 210 and second point
Flow tube road 220 is each configured to access housing from the second heat exchanging segment 302.
It that is to say, the input of the first distribution pipeline 210 and the second distribution 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 distribution pipeline 210 and the second distribution 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 distribution 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 isocon
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 purification assembly 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 distribution pipeline 210 and the second distribution pipeline 220
On two heat exchanging segments 302.So that the windage of purification assembly 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 distribution pipeline 210 and the second distribution 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 purification assembly 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, sky
Working condition of indoor set etc. is adjusted further to set.In some embodiments of the invention, the temperature gap can for 0.5~
Arbitrary temp value between 2 DEG C.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.It is preferred real at some
Apply in example, 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
The regulation of the aperture of electric expansion valve 161 can be avoided 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 purification assembly 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 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, can be with
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.Especially,
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 data branch
Hold, pole contributes to the perfect in shape and function of indoor apparatus of air conditioner.
In the air conditioner room unit of the present invention, purification assembly 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, purification assembly, which is located at, to be moved
Go out air inlet and reach non-purification position；After purification function is opened, purification assembly 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 purification assembly 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
Device, the compressor of outdoor unit and other necessary structures, refrigeration system are applicable to control mode in detail below.
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
