Thereby further reducing the space occupied by the drive means 140.

The base body 146-3 may have a profile that matches the profile of the side cover body 147-3. For example, the base body 146-3 may be formed by connecting two curved sections with different degrees of curvature, the portion of the side cover body 147-3 corresponding to the base body 146-3 may be formed by connecting two curved sections with different degrees of curvature, and the overall shape of the base 146 is similar to that of the side cover 147, so as to facilitate the fastening of the side cover 147 and the base 146.

In some alternative embodiments, referring to FIG. 6, the guide track 147-1 may include a first curved segment 147-1-1 and a second curved segment 147-1-2 contiguous with the first curved segment 147-1-1, the first curved segment 147-1-1 and the second curved segment 147-1-2 may be shaped like an arc, and the first curved segment 147-1-1 and the second curved segment 147-1-2 are curved differently, thereby forming an irregularly shaped guide track 147-1 that matches the path of movement of the purification assembly 150.

The second curved section 147-1-2 is located outside the arc-shaped groove 146-1, that is, the second curved section 147-1-2 is closer to the front panel 130 than the arc-shaped groove 146-1 is located, and the first curved section 147-1-1 is located just below the inner side of the air inlet 121 and is located higher than the first curved section 147-1-1 and the arc-shaped groove 146-1. Therefore, when the cleaning assembly 150 is moved along the irregular-shaped guide 147-1 by the connecting rod 145, the moving path of the cleaning assembly 150 is always located outside the arc-shaped groove 146-1.

In other schemes, the arc-shaped rack 143 drives the purification assembly 150 to cooperate with the arc-shaped guide rail to switch between the purification mode and the non-purification mode, but in this scheme, the space in the indoor unit 100 occupied by the motion path of the purification assembly 150 is large, which affects the arrangement of the indoor unit heat exchanger 160 and the indoor unit fan 170, in this embodiment, the arc-shaped rack 143 drives the purification assembly 150 to move through the connecting rod 145, the motion path of the purification assembly 150 driven by the connecting rod 145 is no longer a regular arc, but moves along the guide rail 147-1 with an irregular shape, which is smaller in the occupied space for the motion of the purification assembly 150, thereby saving the internal space of the two indoor air conditioners 100 and avoiding the influence on the arrangement of the indoor unit heat exchanger 160.

Fig. 7 is a sectional view of a wall-mounted air conditioning indoor unit 100 according to an embodiment of the present invention. In order to clearly and intuitively understand that the purification assembly 150 is directly driven by the arc-shaped rack 143 and the scheme of providing a sliding track for the purification assembly 150 by the arc-shaped guide rail is different from the scheme of driving the purification assembly 150 by the arc-shaped rack 143 through the connecting rod 145 to match the movement of the irregular-shaped guide rail 147-1, fig. 7 shows the path of the irregular-shaped guide rail 147-1 and the arc-shaped guide rail B, as shown in fig. 7, a is the path of the irregular-shaped guide rail 147-1 formed by connecting a first curved section 147-1-1 and a second curved section 147-1-2 with a different arc from the first curved section 147-1-1, B is the path of the regular-shaped arc-shaped guide rail, and the irregular-shaped guide rail 147-1 is positioned outside the arc-shaped guide rail.

If the purification assembly 150 is directly moved along the arc-shaped guide rail by the arc-shaped rack 143, the movement trace of the purification assembly 150 is located at the outer side, and if the purification assembly 150 is moved along the irregularly-shaped guide rail 147-1 by the connecting rod 145, the movement trace of the purification assembly 150 is located at the inner side. Therefore, the cleaning assembly 150 is driven by the connecting rod 145 to move along the irregular-shaped guide rail 147-1 with a smaller space, which can make up more internal space of the indoor unit 100, and does not need to increase the volume of the indoor unit 100, and can provide enough space for the arrangement of the indoor unit heat exchanger 160 and the indoor unit fan 170 while satisfying the arrangement of the driving device 140 and the cleaning assembly 150 in the indoor unit 100, thereby avoiding the need of additionally increasing the internal space of the indoor unit 100 due to the arrangement of the driving device 140.

The second extension portion 155b may be connected to an outwardly extending end of the first extension portion 155a and extend upward. The outer wall of the second extension portion 155b may be formed with a protrusion 155c, the protrusion 155c may abut against a lower surface of an upper end surface of the slot of the first frame 153 corresponding to the first end of the mounting frame 154, so as to clip the first end elastic clip 155 into the slot, and the shape of the second end clip 156 may be adapted to the shape of the slot of the first frame 153 corresponding to the second end of the mounting frame 154, so as to clip the second end clip 156 into the slot. Therefore, the purification module is assembled on the purification module assembling frame, and the installation of the purification module is simplified.

The outer wall of the second extension portion 155b may be formed with two protrusions 155c, the two protrusions 155c are distributed at intervals along a direction parallel to the extending direction of the first frame 153, and the two protrusions 155c are abutted to the lower surface of the upper end surface of the clamping groove of the first frame 153 corresponding to the first end of the mounting frame 154, so as to increase the stability of the connection between the purification module and the purification module assembly frame.

Thereby will purify the module and tear down from purifying module assembly frame, be convenient for change and purify the module. Therefore, the user can directly disassemble and assemble the purification module by hands without professional tools such as a screwdriver, a blade, a wrench and the like when replacing the purification module, and the purification module is simple and convenient to operate, safe and reliable.

When the purge assembly 150 is driven by the driving means 140 to switch between the purge mode and the non-purge mode, the vertical distance of the purge assembly 150 to the surface of the indoor unit heat exchanger 160 is relatively short. Therefore, when the cleaning assembly 150 moves to block a part of the indoor unit 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 indoor heat exchanger 160 generates local temperature difference, and is easy to have the problems of condensation or freezing and the like, so that the heat exchange capability of the indoor heat exchanger is weakened.

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, and is configured to adjust an opening degree of the electronic expansion valve 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 may be plural. The specific number of the electronic expansion valves may be the same as the number of the heat exchange areas, so that each heat exchange area has one electronic expansion valve opposite to the electronic expansion valve, and the input amount of the refrigerant entering the heat exchange area can be directly adjusted and controlled through the electronic expansion valve corresponding to the electronic expansion valve, so that the heat exchange efficiency of each heat exchange area is adapted to the difference generated due to different windage resistances, and the heat exchange effect of each area of the heat exchanger 160 is substantially the same.

The number of the plurality of heat exchange areas is two, and the first heat exchange area is located below the air inlet 121, and the second heat exchange area is located below the front side of the front edge of the air inlet 121, that is, the area corresponding to the inner side of the front panel 130.

When the purifying assembly 150 is driven by the driving device 140 to move to the inner side of the air inlet 121, the purifying assembly 150 covers the air inlet 121, at this time, the position of the purifying assembly 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 purification assembly 150 is the second position, and the corresponding area inside the front panel 130 is the second heat exchange area.

The heat exchanger 160 may have a main guide line for guiding the inflow of the refrigerant and a first guide line and a second guide line for respectively conveying the refrigerant to the first heat exchange area and the second heat exchange area. The electronic expansion valve can be arranged at the input end of the first diversion pipeline or the second diversion pipeline so as to adjust the amount of the refrigerant entering the first diversion pipeline and/or the second diversion pipeline.

In the cleaning module 150, the cleaning module 150 is driven by the driving device 140 to move to a position covering the air inlet 121 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 150 of the indoor unit 100 to start the cleaning mode, the cleaning module 150 is driven by the driving device 140 to move from the inside of the air inlet 121 to the inside of the front panel 130, and the cleaning module 150 does not contact with the ambient air in a large area, 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 100 can immediately adjust the refrigerant input amount of each heat exchange area directly, so as to quickly balance the overall heat exchange effect of the heat exchanger 160 and avoid the phenomenon of excessive local temperature difference of the heat exchanger 160.

In some alternative embodiments, the number of electronic expansion valves may be one. The electronic expansion valve may be disposed at an input end of the second guide line and configured to increase its opening degree to a first opening degree when the purification assembly 150 is moved to the inside of the air inlet 121 by the driving device 140. 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 opening degree of the electronic expansion valve may be increased to increase the refrigerant flowing into the second heat exchange region and decrease the refrigerant flowing into the first heat exchange region. 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 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 opening degree of the electronic expansion valve may be decreased so that the refrigerant flowing into the second heat exchange region is decreased and the refrigerant flowing into the first heat exchange region is increased. Therefore, the heat exchange effect of the first heat exchange area and the second heat exchange area is balanced.

In particular, since the first heat exchange area located below the air inlet 121 is more easily exposed to more ambient air than the second heat exchange area located at the inner front side of the housing 120, the heat exchange efficiency is relatively high. Therefore, the electronic expansion valve may be directly disposed at the input end of the second diversion pipeline 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 indoor unit heat exchanger 160.

In some alternative embodiments, the number of heat exchange areas of the indoor unit heat exchanger 160 may also 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 various heat exchange efficiencies of the indoor unit heat exchanger 160 are not uniform, corresponding refrigerant input amount distribution ratios are respectively set, so that the adjustment of the refrigerant input amount in each branch pipeline of the indoor unit heat exchanger 160 is more accurate and rapid.

This embodiment is through setting up electronic expansion valve at the input of the second water conservancy diversion pipeline in second heat transfer area for when purifying the position change of subassembly 150, only need electronic expansion valve to change a relative less aperture difference and can make the heat transfer pressure in two heat transfer areas obtain the equilibrium, thereby improved electronic expansion valve's governing speed, and make electronic expansion valve's control range more steady, prolonged its life.

Further, specific values of the first opening degree and the second opening degree may be set according to an actual use condition of the indoor unit 100. 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 indoor unit heat exchanger 160 has a three-stage casing including a first heat exchange stage horizontally disposed below the air inlet 121, a second heat exchange stage extending from a front end of the first heat exchange stage to a front side below, and a third heat exchange stage vertically extending downward from a lower end of the second heat exchange stage. The first and second diversion pipes are both configured to tap into the housing 120 from the second heat exchange section.

That is, the input ends of the first diversion pipeline and the second diversion pipeline can be connected to the second heat exchange section 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. Furthermore, pipelines of the first flow guide pipeline and the second flow guide pipeline, which are positioned inside the second heat exchange section, extend in opposite directions respectively, so that the mutual influence of refrigerants in the respective flow guide pipelines of the two heat exchange areas can be avoided.

In some embodiments of the invention, the first heat exchange section and at least a portion of the second heat exchange section form a first heat exchange region. The third heat exchange section and at least a portion of the second heat exchange section form a second heat exchange area. The first flow guide pipeline is bent in the second heat exchange section and extends upwards to the first heat exchange section so as to cover the whole first heat exchange area. The second diversion pipeline is bent in the second heat exchange section and extends downwards to the third heat exchange section so as to cover the whole second heat exchange area.

That is, the upper half of the second heat exchange section belongs to the first heat exchange area, and the lower half of the second heat exchange section belongs to the second heat exchange area. Thus, when the purification assembly 150 is located between the first and second positions, the main effect on the indoor unit heat exchanger 160 is substantially located on the second heat exchange section where the input ends of the first and second diversion pipes 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 and the second diversion pipeline are arranged at the middle section of the indoor unit heat exchanger 160, so that the adjusting range of the opening of the electronic expansion valve can be reduced, the adjusting times of the electronic expansion valve can be reduced, and the operation of the indoor unit 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 may be configured to increase or decrease a preset opening value when the difference between the first surface temperature and the second surface temperature is greater than a preset temperature difference.

That is, the opening degree of the electronic expansion valve may be first adjusted (increased to the first opening degree or decreased to the second opening degree) instantaneously according to the moving position of the purge assembly 150. Then, in the operation process of the indoor unit heat exchanger 160, the electronic expansion valve 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 indoor unit heat exchanger 160 is continuously maintained at approximately 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 indoor unit heat exchanger 160, the purification mode of the indoor unit 100, 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 areas of the indoor unit heat exchanger 160 do not differ too much, and avoid too frequent adjustment of the opening of the electronic expansion valve.

In some embodiments of the invention, where the difference between the first surface temperature and the second surface temperature is greater than the temperature difference, the electronic expansion valve is configured to: the electronic expansion valve increases the opening value when the first surface temperature is less than the second surface temperature. The electronic expansion valve decreases the opening value when the first surface temperature is greater than the second surface temperature. 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 is primarily adjusted according to the moving position of the purification assembly 150, in the working process of the indoor unit 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 indoor wall-mounted unit of the air conditioner is located, and thus the surface temperature of the heat exchanger is unbalanced. At this time, the opening degree of the electronic expansion valve is adjusted to a small extent according to the surface temperature difference of each heat exchange area of the indoor heat exchanger 160, so that the input amount of the cooling medium in the indoor heat exchanger 160 can be regulated in real time, and the local temperature difference on the indoor 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 disposed at the downstream of the main diversion pipeline and at the upstream of the first diversion pipeline and the second diversion pipeline.

Divide liquid adjusting device to have the reposition of redundant personnel chamber, be provided with an elastic component in the reposition of redundant personnel intracavity in order to divide into first subchamber and second subchamber with its inner space to hold the refrigerant of at least part inflow reposition of redundant personnel chamber respectively. Specifically, the liquid separation adjusting device further comprises a main flow guide pipeline, a first flow guide pipeline and a second flow guide pipeline which are communicated with the refrigerant inlet of the main flow guide pipeline. The main diversion pipeline is configured to guide the refrigerant to enter the diversion cavity. The first flow guide pipeline is configured to be communicated with the first sub-chamber so as to guide the refrigerant in the first sub-chamber to flow out of the liquid separation adjusting device. The second flow guide pipeline is configured to be communicated with the second sub-chamber so as to guide the refrigerant in the second sub-chamber to flow out of the liquid separation adjusting device.

Further, the first diversion pipeline is configured to be communicated with the refrigerant receiving opening of the first heat exchange area so as to guide the refrigerant in the first sub-chamber to enter the first heat exchange area. The second diversion pipeline is configured to be communicated with the refrigerant receiving port of the second heat exchange area so as to guide the refrigerant in the second sub-chamber to enter the second heat exchange area.

In some embodiments of the invention, the elastic member is composed of a fixed portion and a movable portion. The fixing part is arc-shaped and is configured to be fixed on the inner wall of the shunting cavity at the peripheral edge. The movable part is configured to connect a part of peripheral side end edge of the movable part with at least part of inner peripheral side end edge of the fixed part, and the other part of peripheral side edge of the movable part is adjacent to at least part of inner peripheral side end edge of the fixed part and/or part of inner wall of the diversion cavity so as to separate the refrigerants in the first sub-cavity and the second sub-cavity and respectively convey the refrigerants in the first sub-cavity and the second sub-cavity to the refrigerant pipelines of the two heat exchange areas.

In some embodiments of the invention, the elastic member may be sheet-like. The fixed part and the movable part may together 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, the elastic component can not receive rather than vertically effort, or this effort is far less than its self resilience force, thereby avoid movable part and fixed part or reposition of redundant personnel intracavity wall between produce the clearance, and then prevent to produce the fluid exchange in first subchamber and the 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 connected to the inner wall of the flow dividing chamber (hereinafter referred to as a connecting portion) is spaced apart from the inlet port of the flow dividing chamber for receiving the refrigerant, with respect to a portion of the movable portion adjacent to at least a portion of an inner peripheral end edge of the fixed portion 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 self, the clearance produces between movable part and the reposition of redundant personnel intracavity wall, and first subchamber and second subchamber communicate with each other to produce the fluid exchange and get into the volume of the refrigerant in first subchamber and the second subchamber respectively in order to adjust.

When the purification assembly 150 is moved 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, so that 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 air 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 that of the refrigerant in the second heat exchange region, so that the fluid pressure in the first heat exchange region is gradually lower than that 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 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 can guide more refrigerant relatively to flow in the second subchamber to the refrigerant volume that the restriction flowed in first subchamber, thereby make the temperature difference and the heat transfer pressure differential of the first heat transfer region of intercommunication with first subchamber and the second heat transfer region of intercommunication with the second subchamber reduce gradually, the effort that produces until the pressure differential of first subchamber and second subchamber is less than the resilience force of elastic component.

The air-conditioning indoor unit of the embodiment divides the refrigerant to flow through the liquid separating adjusting device with the elastic part, so that when the heat exchange effect of each heat exchange area of the heat exchanger is obviously different, the elastic part can automatically adjust the amount of the refrigerant entering each heat exchange area under the action of pressure difference in the liquid separating cavity caused by the difference of the heat exchange effect, and an additional detecting or monitoring device is not needed, thereby simplifying the structure of the air-conditioning indoor unit and reducing the manufacturing cost of the air-conditioning indoor unit.
