In some optional embodiments, as shown in Fig. 4 and Fig. 5, there is one purification module, and the installation frame 154 in Fig. 4 and Fig. 5 is hidden. As shown in Figure 9, there are two purification modules (only one of the purification module bodies 151 is shown in Figure 9), and the two purification modules are arranged successively in their length direction, and the two adjacent purification modules The sides, that is, the two adjacent sides in the width direction of the two purification modules are connected by an intermediate connector. The intermediate connector can have two card slots arranged oppositely, and the two adjacent installation frames of the two purification modules 154 are respectively located in the corresponding slots, thus forming a large-sized whole composed of two purification modules.

Referring to Fig. 9, Fig. 10 and Fig. 11, the purification module assembly frame may include two second frames 152 respectively arranged on the two sides of the purification module in the width direction, and the two oppositely arranged drive devices 140 may be respectively connected with the other The corresponding second frames 152 are connected so that the two driving devices 140 synchronously drive the purification assembly 150 to switch between the purification mode and the non-purification mode, so as to improve the stability of the movement of the purification assembly 150 .

The purification module assembly frame can also include two first frames 153 respectively arranged on two sides of the purification module length direction, and the two ends of each first frame 153 are respectively connected with the corresponding second frame 152, thereby utilizing two One relative first frame 153 and two relative second frames 152 constitute the assembly frame of the purification module, which enhances the stability of the installation of the purification module, prevents the purification module from being damaged or detached from the original position during the movement, and improves the operation of the purification module. safety and service life.

In some optional embodiments, each first frame 153 may have a slot that is consistent with the extending direction of the first frame 153 . Each installation frame 154 can extend from one end to the other end of the side of the purification module body 151 in the width direction, the first end of each installation frame 154 can be formed with a first end elastic buckle 155, the second end of each installation frame 154 The two ends can be formed with second end buckles 156, and the first end of each installation frame 154 is located in the corresponding slot, and is engaged with the slot by the first end elastic buckle 155, and each installation frame 154 The second end of the second end is located in the corresponding slot, and is engaged with the slot through the second end buckle 156 . Thus, the purification module is snapped into the purification module assembly frame, which simplifies the assembly of the purification module and the purification module assembly frame, and because the elastic first end elastic buckle 155 is used, it facilitates the connection between the purification module and the purification module assembly frame. Installation and disassembly, so that the user can replace the purification module more easily after the life of the purification module expires.

In some optional embodiments, referring to FIG. 8 and FIG. 12 , the elastic buckle 155 at the first end may include a first extension portion 155 a and a second extension portion 155 b, and the first extension portion 155 a is formed by the first end of the mounting frame 154 The lower part of the outer wall of the outer wall extends outward, and the “extend outward” here refers to extending away from the first end of the mounting frame 154 . The second extension part 155b may be connected with an outwardly extending end of the first extension part 155a, and extend upward. The outer wall of the second extension part 155b can be formed with a raised part 155c, and the raised part 155c can abut against the lower surface of the upper end surface of the card slot corresponding to the first end of the mounting frame 154, thereby elastically locking the first end. The buckle 155 is snapped into the slot, and the shape of the second end buckle 156 can be adapted to the shape of the slot corresponding to the second end of the mounting frame 154, so that the second end buckle 156 is snapped into the slot middle. In this way, the purification module is assembled on the purification module assembly frame, which simplifies the installation of the purification module.

The outer wall of the second extension part 155b can be formed with two protrusions 155c, and the two protrusions 155c are distributed at intervals along the direction parallel to the extending direction of the first frame 153, and the two protrusions 155c are connected with the mounting frame 154 The lower surface of the upper end surface of the first frame 153 corresponding to the first end of the first frame 153 abuts against the lower surface of the upper end surface, thereby increasing the stability of the connection between the purification module and the purification module assembly frame.

11 and 12, the upwardly extending end of the second extension 155b can be higher than the upper end surface of the slot corresponding to the first end of the installation frame 154, when the purification module is detached from the purification module assembly frame, The user can directly act on the upwardly extending end of the second extension part 155b with his hand, and apply force in a direction away from the slot, so that the protrusion 155c on the second extension part 155b can break away from the slot. Therefore, the purification module is dismantled from the assembly frame of the purification module, which facilitates the replacement of the purification module. In this way, it is realized that the user no longer needs professional tools, such as screwdrivers, blades, wrenches, etc., when replacing the purification module, and can directly disassemble and install it by hand, which is easy to operate, safe and reliable.

When the purification assembly 150 is driven by the driving device 140 to switch between the purification mode and the non-purification mode, the vertical distance between the purification assembly 150 and the surface of the heat exchanger 160 of the indoor unit is relatively short. Therefore, when the purification assembly 150 moves to cover a certain part of the indoor unit heat exchanger 160, a relatively large wind resistance will be generated in this local area, which will affect the heat exchange efficiency of this local area. As a result, a local temperature difference occurs in the heat exchanger 160 of the indoor unit, and problems such as condensation or freezing are prone to occur, thereby weakening its heat exchanging capacity.

To solve the above problems, in some optional embodiments of the present invention, the heat exchanger 160 has multiple heat exchange areas and at least one electronic expansion valve, and is configured to adjust the opening of the electronic expansion valve according to the position of the purification assembly 150 to Control the amount of refrigerant entering multiple heat exchange zones.

There may be multiple electronic expansion valves. The specific number of electronic expansion valves can be the same as the number of heat exchange areas, so that each heat exchange area has a corresponding electronic expansion valve, so that the corresponding electronic expansion valve can directly adjust and control the The input amount of the refrigerant can adapt to the heat exchange efficiency of each heat exchange area due to the difference in wind resistance, so that the heat exchange effect of each area of the heat exchanger 160 is roughly the same.

There are two heat exchange areas, namely the first heat exchange area below the air inlet 121 and the second heat exchange area below the front edge of the air inlet 121 , namely the corresponding area inside the front panel 130 .

When the purification assembly 150 is driven by the driving device 140 to move to the inner side of the air inlet 121, the purification assembly 150 covers the air inlet 121. At this time, the position of the purification assembly 150 is the first position, and the downstream of the air intake path of the air inlet 121 is the first heat exchange zone.

When the cleaning assembly 150 is driven by the driving device 140 to move to the inside of the front panel 130 , the air inlet 121 is exposed. At this time, the position of the purification component 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 general diversion pipeline for guiding the inflow of the refrigerant, and a first diversion pipeline and a second diversion pipeline for transporting the refrigerant to the first heat exchange area and the second heat exchange area respectively. 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 refrigerant entering the first diversion pipeline and/or the second diversion pipeline.

When the cleaning assembly 150 is in the cleaning mode, the cleaning assembly 150 is driven by the driving device 140 to move to a position covering 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 air resistance of the purification assembly 150 . Therefore, it is necessary to limit the refrigerant flowing into the first heat exchange area, and/or increase the refrigerant flowing into the second heat exchange area.

When the air quality of the indoor environment is slightly better, and the user does not require the purification component 150 of the indoor unit 100 to start the purification mode, the purification component 150 is driven by the drive device 140 to move from the inside of the air inlet 121 to the position inside the front panel 130, and the purification component 150 is not in contact with the inside of the front panel 130. Large area contact with ambient air to reduce or avoid contact with air. At this time, the second heat exchange area located on the rear side of the purification unit 150 and substantially perpendicular to the plane where the air inlet 121 is located is more obviously affected by the air resistance of the purification unit 150 . Therefore, it is necessary to limit the refrigerant flowing into the second heat exchange area, and/or increase the refrigerant flowing into the first heat exchange area.

That is, according to different moving positions of the purification component 150 , the heat exchanger 160 can be divided into different heat exchange areas accordingly. Furthermore, when the position of the purification component 150 changes, the indoor unit 100 can directly adjust the refrigerant input volume of each heat exchange area immediately, so as to quickly balance the overall heat exchange effect of the heat exchanger 160, avoiding the heat exchange of the heat exchanger. 160, there is a phenomenon that the local temperature difference is too large.

In some optional embodiments, the number of electronic expansion valves may be one. The electronic expansion valve can be arranged at the input end of the second diversion pipeline, and is configured such that when the purification assembly 150 is driven by the driving device 140 to move to the inside of the air inlet 121, the electronic expansion valve increases its opening to the first opening. . That is, when the purification assembly 150 is located at the first position, its air resistance reduces the air flow passing through the first heat exchange area, thereby reducing the amount of refrigerant exchanged in the first heat exchange area. At this time, the opening of the electronic expansion valve can be increased, so that the amount of refrigerant flowing into the second heat exchange area increases, and the amount of refrigerant flowing into the first heat exchange area decreases. Thus, the heat exchange pressure and heat exchange efficiency of the first heat exchange area and the second heat exchange area are adapted to the air volume flowing through them, so that the heat exchange effects of the two are balanced.

Correspondingly, when the purification assembly 150 is moved to the second position by the driving device 140 , the electronic expansion valve reduces its opening to a second opening which is smaller than the first opening. That is to say, 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 transfer amount of the refrigerant in the second heat exchange area. At this time, the opening of the electronic expansion valve can be reduced, so that the amount of refrigerant flowing into the second heat exchange area decreases and the amount of refrigerant flowing into the first heat exchange area increases. Thus, the heat exchange effects of the first heat exchange area and the second heat exchange area are balanced.

Specifically, since the first heat exchange area located below the air inlet 121 is more likely to be in contact with more ambient air than the second heat exchange area located at the front inside the casing 120 , the heat exchange efficiency is relatively high. Therefore, the electronic expansion valve can be directly installed at the input end of the second diversion pipeline that delivers refrigerant to the second heat exchange area, so that the input amount of refrigerant entering the second heat exchange area can be limited in advance to prevent or properly limit the indoor The mechanical heat exchanger 160 may produce unbalanced heat exchange effects.

In some optional embodiments, the number of heat exchange areas of the indoor unit heat exchanger 160 may also be other values greater than two. Correspondingly, the moving position of the purification component 150 can also be further subdivided. In this embodiment, the multiple moving positions of the purification assembly 150 may respectively correspond to multiple sets of ideal refrigerant input amounts for each heat exchange area. That is, in view of the uneven heat exchange efficiency that may occur in the indoor unit heat exchanger 160, the corresponding refrigerant input flow split ratios are respectively set, so that the refrigerant in each branch pipeline of the indoor unit heat exchanger 160 The adjustment of the input volume is more accurate and rapid.

In this embodiment, the electronic expansion valve is arranged at the input end of the second diversion pipeline in the second heat exchange area, so that when the position of the purification assembly 150 changes, only a relatively small opening difference of the electronic expansion valve is required. The value can balance the heat exchange pressure of the two heat exchange areas, thereby increasing the adjustment speed of the electronic expansion valve, making the adjustment range of the electronic expansion valve more gentle and stable, and prolonging its service life.

Further, the specific values of the first opening degree and the second opening degree can be set according to the actual usage 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%. The second opening can be any opening value between 15% and 50%, for example, it can be 15%, 20%, 25%, 30%, 35%, 40%, 45% or 50%.

In some embodiments of the present invention, the heat exchanger 160 of the indoor unit has a three-section shell, and the shell includes a first heat exchange section horizontally arranged below the air inlet 121, from the front end of the first heat exchange section forward The second heat exchange section extending below the side and the third heat exchange section vertically extending downward from the lower end of the second heat exchange section. Both the first flow guide line and the second flow guide line are configured to connect to the casing 120 from the second heat exchange section.

That is to say, the input ends of the first flow guide line and the second flow guide line can be connected to the second heat exchange section located in the middle of the heat exchanger 160 along the same extending direction. As a result, the mechanism of the refrigerant input pipeline is compact and occupies a small space. Further, the pipes inside the second heat exchange section of the first flow guide line and the second flow guide line respectively extend in opposite directions, so as to avoid refrigerant in the flow guide lines of the two heat exchange regions affect each other.

In some embodiments of the present invention, the first heat exchange section and at least part of the second heat exchange section form a first heat exchange area. The third heat exchange section and at least part of the second heat exchange section form a second heat exchange area. The first guide pipe bends in the second heat exchange section and extends upward to the first heat exchange section, so as to cover the entire first heat exchange area. The second flow guide pipe bends in the second heat exchange section and extends downward to the third heat exchange section, so as to cover the entire 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. Therefore, when the purification assembly 150 is located between the first position and the second position, its main influence on the indoor unit heat exchanger 160 is basically located at the input of the first flow guide line and the second flow guide line. On the second heat exchange section where the end is located. Therefore, the influence of the air resistance of the purification component 150 on the heat exchange effect of the first heat exchange area and the second heat exchange area is relatively similar. Therefore, setting the input ends of the first diversion pipeline and the second diversion pipeline at the middle position of the heat exchanger 160 of the indoor unit can not only reduce the adjustment range of the electronic expansion valve opening, but also reduce its The number of adjustments makes the operation of the indoor unit heat exchanger 160 more stable.

In some embodiments of the present invention, a first temperature sensor and a second temperature sensor (not shown in the figure) are respectively arranged on the outer surfaces of the first heat exchange area and the second heat exchange area, so as to respectively detect the temperature of the first heat exchange area. The first surface temperature of the hot zone and the second surface temperature of the second heat exchange zone. Further, the electronic expansion valve can be configured such that when the difference between the first surface temperature and the second surface temperature is greater than a preset temperature difference, the electronic expansion valve increases or decreases a preset opening value.

That is, the opening of the electronic expansion valve can be adjusted immediately (increasing to the first opening or decreasing to the second opening) according to the moving position of the purification assembly 150 . Then, during the operation of the indoor unit heat exchanger 160, the electronic expansion valve can also be adjusted in real time 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 indoor unit The heat exchange effect of each area of the heat exchanger 160 is continuously maintained at approximately the same level, which ensures the user's use effect.

Specifically, the temperature difference between 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°C and 2°C. For example, it may be 0.5°C, 0.7°C, 0.9°C, 1°C, 1.5°C, 2°C, or the like. In some preferred embodiments, the temperature difference may preferably be 1° C., so as to ensure that the surface temperature of each area of the indoor unit heat exchanger 160 does not vary too much, and to avoid too frequent adjustment of the opening degree of the electronic expansion valve.

In some embodiments of the present invention, when 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: when the first surface temperature is lower than the second surface temperature, the electronic expansion The valve increases the opening value. When the first surface temperature is greater than the second surface temperature, the electronic expansion valve reduces the opening value. Specifically, the preset opening adjustment value may be any value between 1% and 10%. For example, it may be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10%.

That is, after the opening of the electronic expansion valve is initially adjusted according to the moving position of the purification assembly 150, during the working process of the indoor unit heat exchanger 160, the heat exchange between the first heat exchange area and the second heat exchange area The effect may be slightly different due to factors such as the indoor environment of the air-conditioning indoor wall-mounted unit, resulting in uneven surface temperature of the heat exchanger. At this time, according to the surface temperature difference of each heat exchange area of the indoor unit heat exchanger 160, the opening degree of the electronic expansion valve is adjusted in a relatively small range, which can realize real-time regulation of the refrigerant input amount in the indoor unit heat exchanger 160, and quickly The local temperature difference on the heat exchanger 160 of the indoor unit is eliminated. In particular, this kind of fine-tuning can also provide data support for optimizing the preset opening values required for initial adjustments such as the first opening degree and the second opening degree, which is very helpful for the function improvement of the air-conditioning indoor wall-mounted unit.

In some real-time examples of the present invention, the air conditioner indoor unit 100 further includes a liquid separation adjustment device, which is arranged downstream of the main diversion pipeline and upstream of the first diversion pipeline and the second diversion pipeline.

The liquid distribution adjustment device has a distribution cavity, and an elastic member is arranged in the distribution cavity to divide its internal space into a first sub-chamber and a second sub-chamber to respectively accommodate at least part of the refrigerant flowing into the distribution cavity. Specifically, the liquid separation regulating device further includes a total diversion pipeline, a first diversion pipeline and a second diversion pipeline communicated with the refrigerant input port. The main diversion pipeline is configured to guide the refrigerant into the distribution cavity. The first guide line is configured to communicate with the first sub-chamber, so as to guide the refrigerant in the first sub-chamber to flow out of the liquid separation regulator. The second guide line is configured to communicate with the second sub-chamber, so as to guide the refrigerant in the second sub-chamber to flow out of the liquid separation adjustment device.

Further, the first guide pipe is configured to communicate with the refrigerant receiving port of the first heat exchange area, so as to guide the refrigerant in the first subchamber into the first heat exchange area. The second guide pipe is configured to communicate with the refrigerant receiving port of the second heat exchange area, so as to guide the refrigerant in the second subchamber into the second heat exchange area.

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

In some embodiments of the present invention, the elastic member may be in the shape of a sheet. The fixed part and the movable part can jointly form a complete cross-sectional shape, which has the same shape and size as at least one cross-section of the distribution cavity, so as to divide the internal space into two parts.

That is, when the cooling effects of the two heat exchange areas are similar, the heat exchange pressures of the two are relatively balanced, so that the fluid pressures in the first sub-chamber and the second sub-chamber respectively communicated with the two heat exchange areas Roughly equal. Thus, when the pressures in the first sub-chamber and the second sub-chamber are equal, the elastic member will not receive a force perpendicular to it, or the force is much smaller than its own resilience force, thereby avoiding the contact between the movable part and the fixed part. Or there is a gap between the inner walls of the distribution cavity, thereby preventing the fluid exchange between the first sub-chamber and the second sub-chamber, so that the two heat exchange areas can maintain the current relatively balanced heat exchange effect and avoid excessive local temperature difference. The emergence of major situations enhances the stability of the heat exchanger operation.

Further, the part of the fixed part that is connected to the inner wall of the distribution chamber (hereinafter referred to as the connection part) is relative to the part of the movable part that is adjacent to at least part of the inner peripheral edge of the fixed part and/or the inner wall of the distribution chamber ( Hereinafter referred to as the adjacency portion) is away from the input port of the distribution cavity to receive the refrigerant.

Therefore, when the pressures in the first sub-chamber and the second sub-chamber are not equal, the pressure difference between the first sub-chamber and the second sub-chamber will cause the elastic sheet to be subjected to a force perpendicular to it. When the acting force is greater than the resilience of the elastic member itself, a gap is created between the movable part and the inner wall of the distribution cavity, the first sub-chamber and the second sub-chamber communicate with each other, and fluid exchange occurs to regulate the flow into the first sub-chamber respectively The amount of refrigerant in the chamber and the second sub-chamber.

When the cleaning assembly 150 moves and switches between the cleaning position and the non-purifying position, it produces different wind resistances to the two heat exchange areas, which makes the heat exchange efficiency of the two heat exchange areas different.

Specifically, when the purification assembly 150 is located upstream of the air intake path of the first heat exchange area that communicates with the first sub-chamber, the wind resistance of the first heat exchange area increases, the heat exchange efficiency decreases, and the temperature of the refrigerant inside is gradually lower than The temperature of the refrigerant in the second heat exchange area makes the fluid pressure in the first heat exchange area gradually lower than the fluid pressure in the second heat exchange area.

Correspondingly, the fluid pressure in the first subchamber communicating with the first heat exchange area is gradually lower than the fluid pressure in the second subchamber communicating with the second heat exchange area. When the force generated by the fluid pressure difference between the two sub-chambers is greater than the resilience force of the elastic member itself, one end of the movable member located at the adjoining portion is bent toward the first sub-chamber with the lower fluid pressure, thereby making the first sub-chamber The cross-sectional area of the chamber near the refrigerant input port of the distributing chamber is reduced, and the cross-sectional area of the second sub-chamber near the refrigerant inlet of the distributing chamber is increased. Therefore, the curved movable part can guide relatively more refrigerant to flow into the second sub-chamber, and limit the amount of refrigerant flowing into the first sub-chamber, so that the first heat exchange area communicated with the first sub-chamber and the The temperature difference and heat exchange pressure difference of the second heat exchange area connected to the second sub-chamber gradually decrease until the force generated by the pressure difference between the first sub-chamber and the second sub-chamber is smaller than the resilience force of the elastic member .

The air-conditioning indoor unit of this embodiment divides the flow of refrigerant by setting a liquid separation adjustment device with an elastic member, so that when the heat exchange effect of each heat exchange area of the heat exchanger is significantly different, the elastic member can reduce the difference in heat exchange effect. Under the action of the resulting pressure difference in the liquid separation chamber, the amount of refrigerant entering each heat exchange area is automatically adjusted without additional detection or monitoring devices, thereby simplifying the structure of the air conditioner indoor unit and reducing its manufacturing cost.
