The cleaning assembly 150 is moved along the irregular-shaped second guide rail 145-7 by the link 146 between a position inside the front panel 130 and a position inside the intake vent 121, and a moving path of the cleaning assembly 150 is located outside the arc-shaped groove 144-4.

Compared with the scheme that the purification assembly 150 is directly driven by the arc-shaped rack 143 and the first guide rail 145-3 is adopted to provide a sliding track for the purification assembly 150, the space occupied by the connection rod 146 for driving the purification assembly 150 to move in cooperation with the irregular second guide rail 145-7 is smaller, and the internal space of the indoor unit 100 of the air conditioner can be saved.

In order to clearly and intuitively understand that the purification assembly 150 is driven by the arc-shaped rack 143, and the scheme of providing the sliding track for the purification assembly 150 by the first guide rail 145-3 is different from the scheme of driving the purification assembly 150 by the arc-shaped rack 143 through the connecting rod 146 to match the movement of the second guide rail 145-7 with an irregular shape, figure 12 shows the path of the irregularly shaped second guide rail 145-7 and the curved first guide rail 145-3, as shown in fig. 12, a is a path of the irregular-shaped second guide rail 145-7 formed by connecting the first arc-shaped section 145-7-1 and the second arc-shaped section 145-7-2 having a different arc from the first arc-shaped section 145-7-1, B is a path of the arc-shaped first guide rail 145-3, and the irregular-shaped second guide rail 145-7 is positioned outside the arc-shaped first guide rail 145-3.

Accordingly, if the purification assembly 150 is directly moved by the arc-shaped rack 143 along the arc-shaped first guide rail 145-3, the movement trace of the purification assembly 150 is located at the outer side, and if the purification assembly 150 is moved by the connecting rod 146, the movement trace of the purification assembly 150 is located at the inner side. Therefore, the cleaning assembly 150 requires less space to move along the irregular-shaped second guide 145-7 by the connecting rod 146, and can make more internal space of the indoor unit 100, without increasing the volume of the indoor unit 100, and provide enough space for the arrangement of the indoor heat exchanger 160, the fan 170, and other components while arranging the driving device 140 and the cleaning assembly 150.

As shown in fig. 4, 5, 7, 9 and 10, the cleaning assembly 150 can be detachably connected to the driving device 140, so as to facilitate cleaning and replacement of the cleaning assembly 150.

The purification assembly 150 can include a bracket and a purification module 151 disposed on the bracket. The shape and size of the purification module 151 may be determined according to the size of the air inlet 121 and the inner space of the indoor unit 100, and for example, the purification module 151 may have an arc shape.

Purification module 151 can include that static adsorption module, plasma purification module, anion generation module and ceramic activated carbon device etc. that set gradually from outer to inner, and static adsorption module, plasma purification module, anion generation module and ceramic activated carbon device all can be the arc form.

The electrostatic absorption module can adsorb electrified PM2.5 particulate matter, PM2.5 particulate matter in the high-efficient filtration environment, plasma purification module can catch the non-plasma of special use, high-efficient bacterium, virus of killing, and decompose into trace H2O, CO2 entering air, anion generation module can release the anion in to the air, form oxygen anion, high-efficient dust removal sterilization, air-purifying, active air molecule simultaneously, improve human lung function, promote metabolism.

The bracket may include two connecting portions 152 disposed oppositely, and in the scheme that the arc-shaped rack 143 directly drives the purifying assembly 150 to slide along the arc-shaped guide rail, the two connecting portions 152 are directly connected to the corresponding arc-shaped rack 143.

The number of the purification modules 151 may be two, a cross bar 153 may be disposed between the connection portions 152, two ends of the cross bar 153 are respectively connected to the two connection portions 152, a joint portion 154 may be disposed at a middle position of the cross bar 153 to connect the two purification modules 151, and the two purification modules 151 abut against each other at a side of the joint portion 154.

In the case where the arc-shaped rack 143 moves the purification assembly 150 along the irregularly-shaped second guide rail 145-7 by the link 146, the two connection portions 152 are rotatably connected to the corresponding links 146. The purification module 151 is disposed on the connection portion 152 between the two connection portions 152. Specifically, two connecting portions 152 may be oppositely disposed at two opposite end edges of the purification module 151, a first end of the connecting portion 152 is rotatably connected to a second end of the link 146, and a second end of the connecting portion 152 is slidably engaged with the second guide rail 145-7.

The cleaning assembly 150 is driven by the driving device 140 to move between the inner side of the front panel 130 and the inner side of the air inlet 121, and when the cleaning function is not started, the cleaning assembly 150 moves to the inner side of the front panel 130 and is in a non-cleaning position; after the cleaning function is turned on, the cleaning assembly 150 is driven by the driving device to move to the inner side of the air inlet 121 to completely shield the air inlet 121, and is located at the cleaning position to clean the air entering the indoor unit 100.

Because the purification assembly 150 is in purification position and when not purifying the position, the windage that indoor set fan produced the air current is obviously different, after opening purification performance, the air current filters, must lead to the heat transfer effect attenuation through heat exchanger 160, appears high load problem easily, can carry out corresponding control according to the operation mode of air conditioner, makes the air conditioner reduce the influence to the normal refrigeration of air conditioner or heating function when purifying.

For example, after the purification function is turned on, a target tube temperature of the heat exchanger tube temperature of the indoor unit 100 may be set, the heat exchanger tube temperature of the indoor unit 100 may be detected in real time, and the refrigeration system of the air conditioner may be feedback-controlled according to a temperature difference between the detected tube temperature and the target tube temperature.

One specific control method is as follows:

when the air conditioner operates in a cooling mode, if the temperature of the heat exchanger tube after purification is lower than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit 100 can be subjected to feedback control according to the difference, and the lower the temperature of the heat exchanger tube is, the faster the fan rotating speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value with the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured to be maintained within the second temperature difference threshold value with the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the excessively low temperature of the heat exchanger of the indoor unit 100 is prevented.

When the air conditioner performs cooling operation, if the temperature of the heat exchanger tube after purification is higher than the target tube temperature and does not exceed the first temperature difference threshold (for example, 3 degrees), the feedback control can be performed on the fan of the indoor unit 100 according to the difference, and the higher the temperature of the heat exchanger tube is, the faster the fan speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value from the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured within the second temperature difference threshold value from the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the overhigh temperature of the heat exchanger of the indoor unit 100 is prevented.

The first temperature difference threshold and the second temperature difference threshold may be configured according to the specification and the use requirement of the heat exchanger of the indoor unit 100, for example, the first temperature difference threshold is set to plus or minus 3 degrees celsius, and the second temperature difference threshold is set to plus or minus 5 degrees celsius.

In addition, when the purge assembly 150 is driven by the driving means to switch between the purge mode and the non-purge mode, the vertical distance of the purge assembly 150 from the surface of the heat exchanger 160 is relatively short. Thus, when the cleaning assembly 150 moves to block a portion of the heat exchanger 160, a relatively large wind resistance is generated in the local area, which affects the heat exchange efficiency of the local area. Therefore, the heat exchanger 160 generates local temperature difference, and the problems of condensation or freezing and the like are easy to occur, so that the heat exchange capability of the heat exchanger is weakened.

Fig. 13 is a schematic view of a heat exchanger of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention.

To solve the above problem, in some alternative embodiments of the present invention, the heat exchanger 160 has a plurality of heat exchange areas and at least one electronic expansion valve 161, and is configured to adjust an opening degree of the electronic expansion valve 161 according to a position of the purification assembly 150 to control an amount of refrigerant entering the plurality of heat exchange areas.

The electronic expansion valve 161 may be plural. The specific number of the electronic expansion valves 161 may be the same as the number of the heat exchange areas, so that each heat exchange area has one electronic expansion valve 161 opposite to the electronic expansion valve, and the input amount of the refrigerant entering the heat exchange area can be directly adjusted and controlled by the corresponding electronic expansion valve 161, thereby adapting to the heat exchange efficiency of each heat exchange area, which is different due to different windage resistances, and further making the heat exchange effect of each area of the heat exchanger 160 substantially the same.

The number of the plurality of heat exchange areas is two, and the two heat exchange areas are respectively a first heat exchange area located below the air inlet 121 and a front side lower part (a second heat exchange area is an area corresponding to the inner side of the front panel) located at the front edge of the air inlet 121;

when the purifying module 150 is driven by the driving device 140 to move to the inner side of the air inlet 121, the purifying module 150 shields the air inlet, at this time, the position of the purifying module 150 is the first position, and the downstream of the air inlet path of the air inlet 121 is the first heat exchange area.

When the cleaning assembly 150 is driven by the driving device 140 to move to the inner side of the front panel 130, the air inlet 121 is exposed. At this time, the position of the purge assembly 150 is the second position. At this time, the area corresponding to the inner side of the front panel is the second heat exchange area.

The heat exchanger 160 may have a main guide line 162 for guiding inflow of the refrigerant and first and second guide lines 163 and 164 for supplying the refrigerant to the first and second heat exchange regions, respectively. The electronic expansion valve 161 may be disposed at an input end of the first diversion pipeline 163 or the second diversion pipeline 164 to adjust an amount of the refrigerant entering the first diversion pipeline 163 and/or the second diversion pipeline 164.

In the cleaning module 150, in the cleaning mode, the cleaning module 150 is driven by the driving device 140 to move to a position completely shielding the air inlet 121, so as to clean the air entering the indoor unit 100. At this time, the first heat exchange area located inside the purification assembly 150 and below the air inlet 121 is significantly affected by the wind resistance of the purification assembly 150. Thus, it is necessary to restrict the flow of the refrigerant into the first heat exchange region and/or to increase the flow of the refrigerant into the second heat exchange region.

When the indoor ambient air quality is slightly good and the user does not require the cleaning module of the indoor unit 100 to start the cleaning mode, the cleaning module 150 is driven by the driving device 140 to move from a position completely shielding the air inlet 121 to a position inside the front panel 130, and is not in large-area contact with the ambient air, so as to reduce or avoid the contact with the air as much as possible. At this time, the second heat exchange area located at the rear side of the purification assembly 150 and approximately perpendicular to the plane of the air inlet 121 is significantly affected by the wind resistance of the purification assembly 150. Thus, it is necessary to restrict the flow of the refrigerant into the second heat exchange region and/or to increase the flow of the refrigerant into the first heat exchange region.

That is, the heat exchanger 160 may be divided into different heat exchange areas according to different moving positions of the purification assembly 150. Further, when the position of the purification assembly 150 is changed, the indoor unit can immediately adjust the refrigerant input amount of each heat exchange area directly, so that the overall heat exchange effect of the heat exchanger 160 is rapidly balanced, and the phenomenon that the local temperature difference of the heat exchanger 160 is too large is avoided.

In some alternative embodiments, the number of electronic expansion valves 161 may be one. The electronic expansion valve 161 may be disposed at an input end of the second diversion pipeline 164, and configured such that when the purification assembly 150 is driven by the driving device 140 to move to a position shielding the air inlet 121, the electronic expansion valve 161 increases its opening degree to a first opening degree. That is, when the purge assembly 150 is located at the first position, the air resistance thereof reduces the air flow passing through the first heat exchange area, thereby reducing the heat exchange amount of the refrigerant in the first heat exchange area. At this time, the electronic expansion valve 161 may increase the opening degree thereof so that the refrigerant flowing into the second heat exchange region is increased and the refrigerant flowing into the first heat exchange region is decreased. Therefore, the heat exchange pressure and the heat exchange efficiency of the first heat exchange area and the second heat exchange area are adaptive to the air volume flowing through the first heat exchange area and the second heat exchange area, and the heat exchange effects of the first heat exchange area and the second heat exchange area are balanced.

Accordingly, when the purge assembly 150 is moved to the second position by the driving device 140, the electronic expansion valve 161 decreases its opening degree to a second opening degree smaller than the first opening degree. That is, the air resistance of the purification assembly 150 at the second position reduces the air flow passing through the second heat exchange area, thereby reducing the heat exchange amount of the refrigerant in the second heat exchange area. At this time, the electronic expansion valve 161 may decrease the opening degree thereof so that the refrigerant flowing into the second heat exchange region decreases and the refrigerant flowing into the first heat exchange region increases. Therefore, the heat exchange effect of the first heat exchange area and the second heat exchange area is balanced.

Specifically, since the first heat exchange area located below the air inlet 121 is more likely to contact more ambient air than the second heat exchange area located at the front side inside the housing, the heat exchange efficiency is relatively high. Therefore, the electronic expansion valve 161 may be directly disposed at the input end of the second diversion pipeline 164 for delivering the refrigerant to the second heat exchange area, so as to pre-limit the input amount of the refrigerant entering the second heat exchange area, thereby preventing or properly limiting the imbalance of the heat exchange effect possibly generated by the heat exchanger 160.

In alternative embodiments, the number of heat exchange areas of the heat exchanger 160 may be other values greater than two. Accordingly, the movement position of the purge assembly 150 may be further subdivided. In this embodiment, the plurality of moving positions of the purification assembly 150 may respectively correspond to a plurality of sets of ideal refrigerant input amounts of each heat exchange area. That is, for the situation that the heat exchanger 160 may have various uneven heat exchange efficiencies, the corresponding refrigerant input amount distribution ratios are respectively set, so that the adjustment of the refrigerant input amount in each branch pipe of the heat exchanger 160 is more accurate and rapid.

In this embodiment, the electronic expansion valve 161 is disposed at the input end of the second diversion pipeline 164 of the second heat exchange area, so that when the position of the purification assembly 150 is changed, only a relatively small opening difference value is required to be changed by the electronic expansion valve 161, and the heat exchange pressures of the two heat exchange areas can be balanced, thereby increasing the adjustment speed of the electronic expansion valve 161, and making the adjustment amplitude of the electronic expansion valve 161 more stable and stable, and prolonging the service life thereof.

Further, specific values of the first opening degree and the second opening degree can be set according to the actual use condition of the indoor unit. In some embodiments of the present invention, the first opening degree may be any opening degree value between 70% and 80%. For example, it may be 70%, 72%, 74%, 76%, 78%, or 80%, etc. The second opening degree may be any opening degree value between 15% and 50%, and may be 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, or the like, for example.

In some embodiments of the present invention, the heat exchanger 160 has a three-section housing including a first heat exchange section 165 horizontally disposed below the air intake 121, a second heat exchange section 166 extending from a front end of the first heat exchange section 165 to a lower front side, and a third heat exchange section 167 vertically extending downward from a lower end of the second heat exchange section 166. First and second flow conduits 163, 164 are each configured to access the shell from second heat exchange section 166.

That is, the input ends of the first diversion pipeline 163 and the second diversion pipeline 164 can be connected to the second heat exchange section 166 located at the middle position of the heat exchanger 160 along the same extending direction. Therefore, the refrigerant input pipeline mechanism is compact and occupies small space. Further, the first diversion pipeline 163 and the second diversion pipeline 164 located inside the second heat exchange section 166 respectively extend in opposite directions, so that the mutual influence of the refrigerants in the diversion pipelines of the two heat exchange areas can be avoided.

In some embodiments of the present invention, first heat exchange section 165 and at least a portion of second heat exchange section 166 form a first heat exchange zone. Third heat exchange section 167 and at least a portion of second heat exchange section 166 form a second heat exchange zone. The first guide pipe 163 is bent and extended upward in the second heat exchange section 166 to the first heat exchange section 165 to cover the entire first heat exchange area. The second pilot line 164 is bent within the second heat exchange section 166 down to the third heat exchange section 167 to cover the entire second heat exchange area.

That is, the upper half of the second heat exchange section 166 belongs to the first heat exchange area, and the lower half of the second heat exchange section 166 belongs to the second heat exchange area. Thus, when purge assembly 150 is positioned between the first and second positions, its primary effect on heat exchanger 160 is substantially all that is present in second heat exchange section 166 where the input ends of first and second pilot lines 163, 164 are located. Thereby making the windage of the cleaning assembly 150 have a similar effect on the heat exchange effect of the first heat exchange area and the second heat exchange area. Therefore, the input ends of the first diversion pipeline 163 and the second diversion pipeline 164 are both arranged at the middle position of the heat exchanger 160, which can reduce the adjustment range of the opening degree of the electronic expansion valve 161 and the adjustment times thereof, so that the operation of the heat exchanger 160 is more stable.

In some embodiments of the present invention, a first temperature sensor and a second temperature sensor (not shown) are respectively disposed on outer surfaces of the first heat exchange area and the second heat exchange area to respectively detect a first surface temperature of the first heat exchange area and a second surface temperature of the second heat exchange area. Further, the electronic expansion valve 161 may be configured such that when the difference between the first surface temperature and the second surface temperature is greater than a predetermined temperature difference, the electronic expansion valve 161 increases or decreases a predetermined opening value.

That is, the opening degree of the electronic expansion valve 161 may be first adjusted (increased to the first opening degree or decreased to the second opening degree) instantaneously according to the movement position of the purge assembly 150. Then, in the operation process of the heat exchanger 160, the electronic expansion valve 161 can also perform real-time adjustment according to the first surface temperature and the second surface temperature of the first heat exchange area and the second heat exchange area, so that the heat exchange effect of each area of the heat exchanger 160 is continuously maintained at substantially the same level, and the use effect of a user is ensured.

Specifically, the temperature difference value of the first surface temperature and the second surface temperature may be further set according to the performance of the heat exchanger 160, the purification mode of the indoor unit, and the like. In some embodiments of the present invention, the temperature difference may be any temperature value between 0.5 and 2 ℃. For example, the temperature may be 0.5 ℃, 0.7 ℃, 0.9 ℃, 1 ℃, 1.5 ℃, 2 ℃ or the like. In some preferred embodiments, the temperature difference may preferably be 1 ℃, so as to ensure that the surface temperatures of the regions of the heat exchanger 160 do not differ too much, and avoid too frequent adjustment of the opening degree of the electronic expansion valve 161.

In some embodiments of the present invention, in the event that the difference between the first surface temperature and the second surface temperature is greater than the temperature difference, the electronic expansion valve 161 is configured to: when the first surface temperature is less than the second surface temperature, the electronic expansion valve 161 increases the opening value. When the first surface temperature is greater than the second surface temperature, the electronic expansion valve 161 decreases the opening value. Specifically, the preset opening degree adjusting value can be any value between 1% and 10%. For example, it may be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or the like.

That is, after the opening degree of the electronic expansion valve 161 is primarily adjusted according to the moving position of the purification assembly 150, in the operation process of the heat exchanger 160, the heat exchange effect of the first heat exchange area and the second heat exchange area may be slightly different due to the influence of factors such as the indoor environment where the wall-mounted air conditioner is located, and the surface temperature of the heat exchanger is unbalanced. At this time, the opening degree of the electronic expansion valve 161 is adjusted to a small extent according to the surface temperature difference of each heat exchange area of the heat exchanger 160, so that the input amount of the cooling medium in the heat exchanger 160 can be regulated in real time, and the local temperature difference on the heat exchanger 160 can be eliminated rapidly. In particular, the fine adjustment can also provide data support for the preset opening value required when the first opening, the second opening and the like are optimized and adjusted for the first time, and the fine adjustment is greatly beneficial to the functional perfection of the wall-mounted unit in the air conditioner room.

In some embodiments of the present invention, the indoor unit 100 further includes a liquid distribution adjusting device 70 disposed downstream of the main diversion pipeline 162 and upstream of the first diversion pipeline 163 and the second diversion pipeline 164.

Fig. 14 is a schematic front view of the separation regulating device 70 according to one embodiment of the present invention, and fig. 15 is a schematic cross-sectional view of the separation regulating device 70 according to one embodiment of the present invention.

Referring to fig. 14, the liquid-separating adjusting device 70 has a flow-dividing chamber, and an elastic member 700 is disposed in the flow-dividing chamber to divide the inner space of the flow-dividing chamber into a first sub-chamber and a second sub-chamber, so as to respectively accommodate at least part of the refrigerant flowing into the flow-dividing chamber. Specifically, the liquid separation adjusting device 70 further includes a main diversion pipeline 162, a first diversion pipeline 163 and a second diversion pipeline 164, which are communicated with the refrigerant inlet thereof. The main diversion line 162 is configured to direct the refrigerant into the diversion chamber. The first flow guiding pipe 163 is configured to communicate with the first sub-chamber to guide the refrigerant in the first sub-chamber to flow out of the liquid separation regulating device 70. The second guiding pipe 164 is configured to communicate with the second sub-chamber to guide the refrigerant in the second sub-chamber to flow out of the liquid separation regulating device 70.

Further, the first guiding pipeline 163 is configured to communicate with the refrigerant receiving opening of the first heat exchanging region, so as to guide the refrigerant in the first sub-chamber to enter the first heat exchanging region. The second guiding line 164 is configured to communicate with the refrigerant receiving opening of the second heat exchanging region to guide the refrigerant in the second sub-chamber into the second heat exchanging region.

In some embodiments of the present invention, the elastic member 700 is composed of a fixed part 710 and a movable part 720. The fixing portion 710 is arc-shaped and is configured such that the outer peripheral end edge thereof is fixed to the inner wall of the branch chamber. The movable portion 720 is disposed such that a portion of its peripheral edge is connected to at least a portion of the inner peripheral edge of the fixed portion 710, and another portion of its peripheral edge is adjacent to at least a portion of the inner peripheral edge of the fixed portion 710 and/or a portion of the inner wall of the branch chamber, so as to separate the refrigerant in the first sub-chamber and the second sub-chamber and respectively deliver the refrigerant therein to the refrigerant pipes of the two heat exchange regions.

Referring to fig. 15, in some embodiments of the present invention, the elastic member 700 may be a sheet shape. The fixed part 710 and the movable part 720 may form a complete sectional shape having the same shape and size as at least one section of the distribution chamber to divide the inner space thereof into two parts.

That is, when the refrigeration effect of two heat transfer regions is similar, the heat transfer pressure of the two is also comparatively balanced to make respectively with the first subchamber of two heat transfer regional intercommunications and the fluid pressure of second subchamber roughly equal. From this, when the pressure in first subchamber and the second subchamber is equal, elastic component 700 can not receive rather than vertically effort, or this effort is far less than its self resilience force, thereby avoid movable part 720 and fixed part 710 or shunt intracavity wall between produce the clearance, and then prevent the indoor fluid exchange that produces of first subchamber and second subchamber, so that current comparatively balanced heat transfer effect can be maintained in two heat transfer regions, avoid its appearance of the too big condition of local difference in temperature, the stability of heat exchanger operation has been strengthened.

Further, a portion of the fixed portion 710 connected to the inner wall of the flow dividing chamber (hereinafter, referred to as a connecting portion) is away from the inlet of the flow dividing chamber for receiving the refrigerant, with respect to a portion of the movable portion 720 adjacent to at least a portion of the inner circumferential end edge of the fixed portion 710 and/or the inner wall of the flow dividing chamber (hereinafter, referred to as an adjacent portion).

Thus, when the pressures within the first and second sub-chambers are not equal, the pressure differential between the first and second sub-chambers causes the resilient sheet to be subjected to forces perpendicular thereto. When this effort is greater than the resilience force of elastic component 700 self, clearance is produced between movable part 720 and the reposition of redundant personnel intracavity wall, first sub-chamber and second sub-chamber intercommunication each other to produce the fluid exchange and get into the volume of the refrigerant in first sub-chamber and the second sub-chamber respectively.

When the purification assembly moves and switches between the purification position and the non-purification position, the wind resistance generated by the purification assembly to the two heat exchange areas is different, and then the heat exchange efficiency of the two heat exchange areas is different.

Specifically, when the purification assembly 150 is located at the upstream of the air inlet path of the first heat exchange region communicated with the first sub-chamber, the wind resistance of the first heat exchange region is increased, the heat exchange efficiency is reduced, and the temperature of the refrigerant therein is gradually lower than the temperature of the refrigerant in the second heat exchange region, so that the fluid pressure in the first heat exchange region is gradually lower than the fluid pressure in the second heat exchange region.

Accordingly, the fluid pressure within the first sub-chamber communicating with the first heat exchange region is progressively less than the fluid pressure within the second sub-chamber communicating with the second heat exchange region. When the effort that the fluid pressure difference of two subchambers produced was greater than the resilience force of elastic component 700 self, the one end atress that is located the adjacent part of moving part was crooked to the little first subchamber of fluid pressure to make the cross-sectional area that first subchamber is close to the refrigerant input of reposition of redundant personnel chamber reduce, and make the second subchamber be close to the cross-sectional area increase of the refrigerant input of reposition of redundant personnel chamber. From this, crooked movable part 720 can guide more relatively refrigerant to flow into the second subchamber to the refrigerant volume that the restriction flowed into in the first subchamber, thereby make the temperature difference and the heat transfer pressure difference of the first heat transfer region of intercommunication with the first subchamber and the second heat transfer region of intercommunication with the second subchamber reduce gradually, until the effort that the pressure difference of first subchamber and second subchamber produced is less than the resilience force of elastic component 700.

The air-conditioning indoor unit of the invention divides the refrigerant by arranging the liquid separation adjusting device 70 with the elastic part 700, so that when the heat exchange effect of each heat exchange area of the heat exchanger is obviously different, the elastic part 700 can automatically adjust the amount of the refrigerant entering each heat exchange area under the action of the pressure difference in the liquid separation cavity caused by the difference of the heat exchange effect, and no additional detection or monitoring device is needed, thereby simplifying the structure of the air-conditioning indoor unit and reducing the manufacturing cost thereof.

In the wall-mounted air conditioner indoor unit 100 of this embodiment, the purifying assembly 150 is disposed inside the dust filter mesh 123, and is driven by the driving device 140 to move between the inside of the front panel 130 and the inside of the air inlet 121, and when the purifying assembly 150 is driven by the driving device 140 to move to the inside of the air inlet 121, the air inlet 121 can be completely shielded, so that the air flow entering the indoor unit 100 after being filtered by the dust filter mesh 123 can be purified, and the air quality of the indoor environment can be improved; the cleaning assembly 150 can also be driven by the driving device 140 to move to the inner side of the front panel 130, exposing the air inlet 121, so that the airflow is filtered by the dust filter 123 and then does not directly enter the indoor unit 100 through the cleaning assembly 150. The expansion of the functions and the flexibility of use of the indoor unit 100 of the air conditioner are realized.

Further, in the wall-mounted air conditioning indoor unit 100 of the embodiment, the second guide rail 145-7 is formed by connecting the first arc-shaped section 145-7-1 and the second arc-shaped section 145-7-2 having a different radian from the first arc-shaped section 145-7-1, so that an irregular-shaped guide rail is formed, the second arc-shaped section 145-7-2 at a lower position is located outside the arc-shaped groove, the gear 142 drives the arc-shaped rack 143 to slide in the arc-shaped groove 144-4, the arc-shaped rack 143 is connected with the purifying assembly 150 through the connecting rod 146, the purifying assembly 150 is driven by the connecting rod 146 to cooperate with the irregular-shaped guide rail to move, so that the moving path of the purifying assembly 150 is located outside the arc-shaped groove 144-4, thereby saving the internal space of the indoor unit 100, facilitating the arrangement of the indoor heat exchanger 160 and the fan 170, the volume of the indoor unit 100 is reduced.
