Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a wall-mounted air conditioner indoor unit. Background Technology

[0002] Household air conditioning units can be divided into two types based on their structure: modular air conditioners and split-type air conditioners. Split-type air conditioners commonly include floor-standing and wall-mounted models. Wall-mounted air conditioners are popular due to their compact structure and space-saving design. The indoor unit of a wall-mounted air conditioner houses a heat exchanger, filter, and motor. The motor drives a cross-flow fan to rotate, which blows air out of the indoor unit, creating a negative pressure difference. Air from the room enters the indoor unit through the upper grille, passes through the filter, exchanges heat with the heat exchanger, and is then blown out through the outlet, thus completing the cycle.

[0003] In existing technologies, due to the limited air intake capacity of the air inlet at the top of the casing, some wall-mounted air conditioners employ a movable front panel design. This design uses a drive assembly to open the front of the casing, allowing for additional air intake and effectively increasing the air volume. However, in existing technologies, the drive assembly exhibits significant movement play during transmission, resulting in poor motion synchronization. Therefore, structural optimization is needed to reduce movement play during transmission. Utility Model Content

[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-14 The wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model can effectively reduce transmission levels, thereby reducing motion misalignment in the transmission path and improving overall motion synchronization.

[0021] Combination Figures 1-14 As shown, the wall-mounted air conditioner indoor unit 100 according to the first aspect of the present invention includes a housing 10, an indoor heat exchanger, and a drive assembly 20.

[0022] Among them, the casing 10 serves as the main load-bearing structural component of the wall-mounted air conditioner indoor unit 100, which can protect the internal structure and accommodate the installation; the indoor heat exchanger can exchange heat with the indoor air (when cooling, it quickly absorbs heat from the indoor air and then transfers the heat to the outside with the help of refrigerant circulation; when heating, it releases heat in the opposite direction); the drive component 20 can provide driving force.

[0023] The housing 10 includes an outer cover 11 and a front panel 12. The outer cover 11 has an air inlet 111 and an air outlet 112. The front panel 12 is movably disposed on the front side of the outer cover 11. An indoor heat exchanger is disposed inside the outer cover 11 and is located between the air inlet 111 and the air outlet 112 to exchange heat with the air entering from the air inlet 111.

[0024] The wall-mounted air conditioner indoor unit 100 can draw in indoor air through the air inlet 111 and blow the air that has been heat-treated by the indoor heat exchanger back into the room through the air outlet 112, thereby forming a circulating effect of indoor air, which is conducive to continuous heat exchange of indoor air.

[0025] The drive assembly 20 is disposed inside the outer cover 11 and is connected to the front panel 12 for transmission, so that the front panel 12 selectively opens and closes the front side of the outer cover 11.

[0026] The drive assembly 20 is housed inside the outer cover 11, which protects the drive assembly 20 from external interference and collision risks, thereby extending its service life. The drive assembly 20 is connected to the front panel 12, meaning it provides driving force to the front panel 12. This allows the front panel 12 to selectively open and close the front side of the outer cover 11, thus enabling it to respond to whether the wall-mounted air conditioner indoor unit 100 is turned on or off.

[0027] Optionally, when the current panel 12 is fully opened under the driving force of the drive component 20, the entire air outlet 112 and the human sensor camera can be exposed, and the air intake can be increased (since the front of the outer cover 11 is also provided with an air inlet 111), thereby increasing the air supply intensity and air supply efficiency, and also allowing the air inside the casing 10 to be blown out smoothly from the air outlet 112.

[0028] There are at least two drive components 20, which are spaced apart in the left-right direction. At least one drive component 20 includes a drive element 21 and a reduction mechanism 22. The reduction mechanism 22 is disposed inside the outer cover 11 and is drively connected to the drive element 21. Each drive component 20 includes a transmission mechanism 23, one end of which is connected to the front panel 12. For example, the drive element 21 can be a motor. Stepper motors have the characteristics of simple control, precise positioning, low cost, and fast response, which facilitates the drive element 21 to provide driving force.

[0029] Optionally, the drive assembly 20 may consist of a drive element 21, a reduction mechanism 22 and a transmission mechanism 23, or the drive assembly 20 may consist of only the transmission mechanism 23.

[0030] Among them, the drive components 20 arranged on the left and right sides can cover a wider range of action, avoiding the problem of one-sided force due to insufficient force coverage of a single drive component 20, thereby improving the uniformity of force on the front panel 12 during the lifting and opening / closing process, and ensuring that the front panel 12 can normally and stably achieve the lifting and opening / closing action.

[0031] Furthermore, when the drive component 21, the reduction mechanism 22, and the transmission mechanism 23 constitute the main body of the drive assembly 20, the reduction mechanism 22 is located inside the outer cover 11. The outer cover 11 can protect the reduction mechanism 22 and prevent it from being interfered with or collided with by other external objects, thereby extending the service life of the reduction mechanism 22. Moreover, the reduction mechanism 22 is connected to the drive component 21 in a transmission manner, and the driving force of the drive component 21 can be transmitted to the reduction mechanism 22. The reduction mechanism 22 can increase the transmission torque of the drive component 21.

[0032] Furthermore, the transmission mechanism 23 is connected to the reduction mechanism 22, and the transmission mechanism 23 is also connected to the front panel 12. The power transmission of the drive component 21 is sequentially transmitted to the reduction mechanism 22, the transmission mechanism 23 and the front panel 12. The reduction mechanism 22 can increase the driving torque of the drive component 21, so that the drive component 21 with lower power consumption can be used for driving, thereby reducing the space occupied by the drive component 21. Moreover, the above arrangement can also ensure that the front panel 12 can move relative to the outer cover 11.

[0033] Specifically, a transmission rod 30 is provided between the transmission mechanisms 23 of two adjacent drive components 20. The transmission rod 30 is connected to the reduction mechanism 22 of the drive component 20, and the transmission rod 30 is also connected to the other end of the transmission mechanism 23 of the two adjacent drive components 20.

[0034] Among them, the drive components 20 arranged at intervals in the left and right directions (provided that at least one drive component 20 has a drive element 21) can be equipped with a drive element 21 as needed. The transmission rod 30 can connect and integrate multiple drive components 20 in series, so that the driving force is transmitted to each drive component 20 through the transmission rod 30. This facilitates the transmission of the driving force of the drive element 21 to the front panel 12 through the transmission mechanism 23 on each drive component 20. That is, the driving force is evenly transmitted from the left and right ends to the middle or along the overall working surface, preventing the front panel 12 from tilting, jamming or local overload due to uneven power at both ends, and ensuring that the front panel 12 remains stable during movement.

[0035] In addition, the transmission rod 30 can forcefully ensure the synchronous movement of multiple drive components 20. Without the connection of the transmission rod 30, the drive components 20 spaced apart on the left and right may move asynchronously due to factors such as motor speed deviation and uneven load resistance (such as one end moving faster and the other slower), which may lead to deformation of related parts or movement jamming. With its rigid connection characteristics, the transmission rod 30 can force all drive components 20 to maintain a consistent movement rhythm (such as synchronous rotation and synchronous lifting), thereby improving the movement accuracy and coordination of the front panel 12.

[0036] Furthermore, the transmission rod 30 can enhance the overall drive assembly 20's resistance to deformation. While connecting the spaced drive assemblies 20, the transmission rod 30 can also serve as a lateral support structure, filling the structural gap between the left and right drive assemblies 20. When the front panel 12 is subjected to lateral force or vibration, the transmission rod 30 can disperse the impact force, avoiding the risk of damage to a single drive assembly 20 due to excessive independent force.

[0037] Furthermore, since the transmission rod 30 is connected to the reduction mechanism 22 while also being connected to the other end of the transmission mechanism 23 of the two adjacent drive components 20, the drive member 21 can transmit the driving force along the path of drive member 21 - reduction mechanism 22 - transmission rod 30 - transmission mechanism 23 of the two adjacent drive components 20. Thus, when the reduction mechanism 22 drives the transmission rod 30 to rotate, the two adjacent drive components 20 in the left and right directions can rotate synchronously with the transmission rod 30, which improves the motion synchronization of the two adjacent drive components 20 and the transmission rod 30 and reduces motion play.

[0038] Compared to the traditional method using a movable front panel (whose drive assembly transmission sequence is reduction mechanism - right drive mechanism - transmission rod - left drive mechanism), the embodiment in this case can reduce the number of transmission levels, reduce motion misalignment in the transmission path, and improve overall motion synchronization.

[0039] Therefore, by setting up the wall-mounted air conditioner indoor unit 100, the transmission levels can be effectively reduced, thereby reducing motion misalignment in the transmission path and improving overall motion synchronization.

[0040] According to some optional embodiments of the present invention, combined with Figures 4-10 As shown, the transmission mechanism 23 includes a panel connector 231 and a rocker arm 232. The panel connector 231 is disposed on the front panel 12. One end of the panel connector 231 is slidably disposed on the outer cover 11. One end of the rocker arm 232 is rotatably connected to the other end of the panel connector 231. The other end of the rocker arm 232 is connected to the transmission rod 30.

[0041] The drive component 21 transmits the driving force to the reduction mechanism 22, and then to the transmission rod 30, rocker arm 232 and panel connector 231 in sequence. This makes it easier for the panel connector 231 to drive the front panel 12 to move, so as to smoothly achieve the effect of opening and closing the front panel 12.

[0042] Specifically, in combination Figures 5-7As shown, the reduction mechanism 22 includes at least one reduction gear set 221. The at least one reduction gear set 221 is sequentially driven between the drive member 21 and the rocker arm 232 near the drive member 21. The reduction gear set 221 includes at least two meshing first gears 2211 and second gears 2212. The first gears 2211 are connected to the drive member 21, and the second gears 2212 are disposed on the rocker arm 232 and the transmission rod 30.

[0043] Among them, the reduction gear set 221 can use the difference in the number of teeth of the first gear 2211 and the second gear 2212 (usually the first gear 2211 is a small gear and the second gear 2212 is a large gear) to achieve the effect of speed reduction and torque increase. That is, the high speed of the driving component 21 is converted into the low speed movement required by the rocker arm 232 and the transmission rod 30. At the same time, according to the principle that the torque of the gear transmission is inversely proportional to the speed, the output torque is amplified synchronously to meet the high torque requirements of the rocker arm 232 and the transmission rod 30 when driving the load (such as the front panel 12) to perform reciprocating or rotating motion.

[0044] Furthermore, the design of the drive component 21 directly driving the first gear 2211 and the second gear 2212 to drive the rocker arm 232 and the transmission rod 30 can minimize the number of intermediate transmission components. This can reduce the motion play in the transmission process from the drive component 21 to the transmission mechanism 23, and also reduce the power loss in the transmission process (such as friction loss and clearance loss), i.e., assembly play. It can also avoid slippage problems through the rigid transmission characteristics of gear meshing, ensuring that the power of the drive component 21 can be stably and efficiently transmitted to the rocker arm 232 and the transmission rod 30.

[0045] Furthermore, combined Figures 12-14 As shown, along the axial direction of the transmission rod 30, the rocker arm 232 is provided with a through hole 2321, the second gear 2212 is provided with a groove 2213, one end of the transmission rod 30 is provided in the groove 2213, and the transmission rod 30 passes through the through hole 2321. The transmission rod 30 is in circumferential upper limit engagement with the through hole 2321 and the groove 2213 respectively.

[0046] It is understandable that the transmission rod 30 is engaged with the through hole 2321 on the rocker arm 232 and the groove 2213 on the second gear 2212 in the circumferential upper limit of the transmission rod 30. This is beneficial to constructing a rigid transmission link with no relative slippage, thereby ensuring the motion synchronization and power transmission stability of the second gear 2212, the transmission rod 30 and the rocker arm 232.

[0047] The above arrangement helps to completely eliminate the gaps between the transmission rod 30 and the through hole 2321 and the groove 2213 in the rotation direction of the transmission rod 30, avoiding relative free rotation or slippage of the transmission rod 30. This ensures that the torque of the first gear 2211 can be transmitted to the rocker arm 232 through the transmission rod 30 without loss or delay. That is, when the second gear 2212 is driven to rotate by the drive member 21, it will directly pull the transmission rod 30 through the circumferential limiting fit with the transmission rod 30, and then the transmission rod 30 will synchronously drive the rocker arm 232 to rotate. Therefore, there will be no power transmission interruption due to the circumferential fit gap (for example, the second gear 2212 rotates but the transmission rod 30 does not rotate or the transmission rod 30 rotates but the rocker arm 232 lags behind), thereby effectively reducing the generation of motion play and improving the motion synchronization of the drive mechanism.

[0048] Furthermore, the circumferential upper limit engagement between the transmission rod 30 and the through hole 2321 and the groove 2213 respectively can force the transmission rod 30, the second gear 2212, and the rocker arm 232 to maintain absolute synchronous movement in the rotation direction of the transmission rod 30. This allows the rotation angle of the second gear 2212 to be accurately converted into the rotation angle of the rocker arm 232, avoiding motion errors of the rocker arm 232 caused by the relative rotation of the three components, thereby improving the motion accuracy and synchronization of the drive mechanism.

[0049] Specifically, in combination Figure 6 , Figures 12-14 As shown, in the direction perpendicular to the axial direction of the transmission rod 30, the cross-sectional shape of the transmission rod 30 is constructed as a polygon, and the shapes of the through hole 2321 and the groove 2213 correspond to the cross-sectional shape of the transmission rod 30.

[0050] The polygonal transmission rod 30 can have multiple straight sidewalls. Since the shapes of the through hole 2321 and the groove 2213 correspond to the cross-sectional shape of the transmission rod 30, it is easy for the transmission rod 30 to form a fully fitted surface contact limit with the through hole 2321 and the groove 2213 respectively. This can avoid the circumferential rotation gap that may exist in the circular or arc-shaped fit, and prevent the transmission rod 30 from slipping or spinning relative to the through hole 2321 and the groove 2213. This ensures that the three are completely synchronized during power transmission, thereby effectively eliminating circumferential motion play, improving transmission accuracy, and thus improving the motion synchronization of the drive component 20.

[0051] Furthermore, the multi-faceted contact of the polygonal fit can evenly distribute torque and load impact to multiple sidewalls, reducing local contact stress concentration, effectively enhancing load-bearing capacity and fatigue resistance, and extending the service life of the components; at the same time, the polygonal geometry has a misalignment prevention function, that is, the transmission rod 30 can only be matched and assembled with the through hole 2321 on the rocker arm 232 and the groove 2213 on the second gear 2212 at a fixed angle, which can effectively avoid installation errors caused by angular misalignment during assembly, simplify the assembly process and reduce the risk of rework.

[0052] Furthermore, combined Figure 6 , Figures 12-14 As shown, the rocker arm 232 near the second gear 2212 has a first circumferential limiting part 2322 on the side surface facing the second gear 2212, and the second gear 2212 has a second circumferential limiting part 2214 on the side surface near the rocker arm 232. The first circumferential limiting part 2322 and the second circumferential limiting part 2214 are in a circumferential limiting engagement with the transmission rod 30.

[0053] The first circumferential limiting part 2322 on the rocker arm 232 and the second circumferential limiting part 2214 on the second gear 2212 are engaged in a circumferential limiting engagement with the transmission rod 30. This allows the rocker arm 232 and the second gear 2212 to establish a stop connection, and also effectively limits the relative rotation between them in the circumferential direction of the transmission rod 30. This avoids the generation of circumferential rotation gaps between them based on the connection, and prevents relative slippage or free rotation. It ensures that the two are completely synchronized during power transmission, thereby effectively eliminating circumferential movement play during transmission, improving transmission accuracy, and thus improving the motion synchronization of the drive assembly 20.

[0054] Specifically, the first circumferential limiting part 2322 is constructed as one of a limiting protrusion and a limiting groove 2213 that are spaced apart circumferentially around the through hole 2321 along the transmission rod 30, and the second circumferential limiting part 2214 is correspondingly constructed as the other of a limiting groove 2213 and a limiting protrusion that are spaced apart circumferentially around the groove 2213 along the transmission rod 30, with the limiting protrusion and the limiting groove 2213 being adapted to each other.

[0055] When the first circumferential limiting part 2322 is configured as a limiting protrusion, the second circumferential limiting part 2214 is configured as a limiting groove 2213; when the first circumferential limiting part 2322 is configured as a limiting groove 2213, the second circumferential limiting part 2214 is configured as a limiting protrusion.

[0056] Optionally, when the first circumferential limiting part 2322 is constructed as a limiting protrusion, the second circumferential limiting part 2214 is constructed as a limiting groove 2213. The shapes of the limiting protrusion and the limiting groove 2213 are adapted and matched to each other, which makes it easier for the rocker arm 232 and the second gear 2212 to achieve a limiting engagement relationship through a complementary structural form, thereby eliminating the circumferential rotation gap between the two during the transmission process, and thus improving the motion synchronization and accuracy of the two during the motion process.

[0057] Furthermore, combined Figures 7-14 As shown, the transmission mechanism 23 also includes a main housing 233 and a first cover plate 234. The main housing 233 is disposed on the outer cover 11, and part of the rocker arm 232 is disposed inside the main housing 233. The first cover plate 234 is located on the side of the main housing 233 near the rocker arm 232. The main housing 233 is provided with a first snap-fit ​​part 2331, and the first cover plate 234 is provided with a second snap-fit ​​part 2341. The first snap-fit ​​part 2331 and the second snap-fit ​​part 2341 are engaged in a snap-fit ​​relationship.

[0058] The main housing 233 provides installation space for the rocker arm 232. The first cover plate 234 is connected to the side of the main housing 233 near the rocker arm 232. The main housing 233 and the first cover plate 234 can jointly provide more comprehensive protection for the rocker arm 232. Moreover, the main housing 233 and the first cover plate 234 are connected by a split connection, which makes it easier to disassemble and replace the rocker arm 232 inside the main housing 233, thus improving the ease of disassembly and assembly of the rocker arm 232.

[0059] Furthermore, the first snap-fit ​​portion 2331 on the main shell 233 and the second snap-fit ​​portion 2341 on the first cover plate 234 snap-fit ​​together, which allows the main shell 233 and the first cover plate 234 to be connected as a whole. Moreover, compared with other connection methods (such as screw connection, adhesive connection, etc.), the snap-fit ​​connection does not require additional parts to connect the main shell 233 and the first cover plate 234 as a whole, avoiding unnecessary additional material consumption. It can also provide sufficient connection holding force between the main shell 233 and the first cover plate 234 to ensure that the first cover plate 234 will not fall off the main shell 233.

[0060] Moreover, the snap-fit ​​connection structure is simple and reliable, and has quick and convenient disassembly and installation functions (that is, it can realize the quick combination and separation of the main shell 233 and the first cover plate 234), which can effectively reduce the time and cost required for maintenance and replacement.

[0061] Specifically, in combination Figure 7 , Figure 8 and Figure 14As shown, the transmission mechanism 23 near the deceleration mechanism 22 also includes a second cover plate 235. The second cover plate 235 is disposed on the side of the main housing 233 away from the rocker arm 232. A first receiving cavity 236 is formed between the second cover plate 235 and the main housing 233. The second gear 2212 is disposed in the first receiving cavity 236. The second cover plate 235 has an opening for the second gear 2212 to extend out and mesh with the first gear 2211.

[0062] It is understood that a first receiving cavity 236 is formed between the second cover plate 235 and the main housing 233 for installing and accommodating the second gear 2212, and an opening is formed on the second cover plate 235. This allows the second cover plate 235 to make space clearance for the second gear 2212, so that the second cover plate 235 in the first receiving cavity 236 can extend smoothly and mesh with the external first gear 2211, thereby improving the design rationality of the second cover plate 235.

[0063] Alternatively, combined Figure 7 , Figure 8 and Figure 14 As shown, the second cover plate 235 is provided with a third circumferential limiting part 2342, and the second gear 2212 is constructed as an incomplete gear. When the second gear 2212 rotates relative to the second cover plate 235 to the limit position, the third circumferential limiting part 2342 and the end edge of the second gear 2212 in the circumferential direction are engaged in a limiting fit in the rotation direction of the second gear 2212.

[0064] When the second gear 2212 rotates to its limit position relative to the second cover plate 235, the third circumferential limiting part 2342 on the second cover plate 235 and the circumferential end edge of the second gear 2212 engage with the upper limit in the rotation direction of the second gear 2212. At this time, the second gear 2212 will be unable to continue rotating along the original rotation trend (that is, the limit position of the second gear 2212 rotating around the rotation axis in a clockwise or counterclockwise direction), thereby limiting the rotation angle of the second gear 2212, preventing the second gear 2212 from rotating to an undesirable position, and thus ensuring the rationality of the final opening angle of the front panel 12.

[0065] Alternatively, combine Figure 7 , Figure 8 and Figure 14 As shown, one of the main housing 233 and the second cover plate 235 is provided with a mounting post 2332, and the mounting post 2332 is provided with a mounting hole. The other of the main housing 233 and the second cover plate 235 is provided with a through hole 237. Fasteners pass through the through hole 237 and the mounting hole to connect the main housing 233 and the second cover plate 235 into a whole. For example, the fastener can be a screw.

[0066] When the main shell 233 is provided with a mounting post 2332, the second cover plate 235 is provided with a through hole 237; when the main shell 233 is provided with a through hole 237, the second cover plate 235 is provided with a mounting post 2332.

[0067] Optionally, the main housing 233 is provided with a mounting post 2332, and the second cover plate 235 is provided with a through hole 237. After the fastener passes through the through hole 237 and the mounting hole on the mounting post 2332 in sequence, the main housing 233 and the second cover plate 235 are connected into a solid whole. The mounting post 2332 can provide a clear assembly positioning reference, so that the through hole 237 of the second cover plate 235 can be quickly and accurately aligned with the mounting hole, avoiding the offset error during manual alignment and effectively improving the assembly efficiency.

[0068] Moreover, compared to adhesive bonding, the main shell 233 and the second cover plate 235 in this case are connected by fasteners. This method has higher connection stability and better disassembly. When internal components need to be repaired later, the shell and cover plate can be separated simply by removing the fasteners. The operation is convenient and will not cause destructive damage to the parts, thereby effectively improving economy and practicality.

[0069] The air conditioner includes a wall-mounted indoor unit 100 and an outdoor unit, which are connected by pipes to transfer refrigerant. The indoor unit 100 includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, outdoor heat exchanger, expansion valve, and indoor heat exchanger, connected in sequence, form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor and indoor heat exchangers to achieve the air conditioner's cooling or heating mode. The compressor is configured to compress the refrigerant, thereby compressing the low-pressure refrigerant into a high-pressure refrigerant.

[0070] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of a cabinet air conditioner, the outdoor heat exchanger functions as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the cabinet air conditioner, the outdoor heat exchanger functions as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0071] In some embodiments, the outdoor heat exchanger further includes fins to increase the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0072] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet 111 and discharge the outdoor air, after heat exchange with the outdoor heat exchanger, through the outdoor air outlet 112. The outdoor fan provides power for the flow of outdoor air.

[0073] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve, and its opening degree is adjustable to control the refrigerant flow rate and pressure.

[0074] The four-way valve is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the cabinet air conditioner can perform cooling mode or heating mode.

[0075] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat from the outdoor heat exchanger, to absorb heat from the indoor air and evaporate. In the heating mode of the air conditioner, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat from the outdoor heat exchanger, to dissipate heat to the indoor air and condense.

[0076] In some embodiments, the indoor heat exchanger further includes fins to increase the contact area between indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant. An indoor fan is configured to draw indoor air into the indoor unit through the air inlet 111 and to discharge the indoor air, after heat exchange with the indoor heat exchanger, through the air outlet 112 of the indoor unit. The indoor fan provides power for the flow of indoor air.

[0077] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include a fan. The fan is disposed inside the outer casing 11, and the axial direction of the fan extends along the length of the casing 10. It is used to drive indoor air outside the casing 10 into the heat exchange duct inside the casing 10 through the air inlet 111. The fan drives the air in the heat exchange duct to flow along the air inlet 111 toward the air outlet 112.

[0078] The fan is located below the indoor heat exchanger. The indoor heat exchanger can be located inside the air inlet 111. The fan can be located on the side of the indoor heat exchanger away from the air inlet 111. That is, in the airflow direction within the casing 10, the fan is downstream of the indoor heat exchanger.

[0079] When the indoor unit 100 of the wall-mounted air conditioner is running, indoor air enters the outer casing 11 from the air inlet 111 under the operation of the fan. The indoor air in the heat exchange duct flows through the indoor heat exchanger for heat exchange. The heat-exchanged airflow is discharged to the outside of the room through the air outlet 112, thereby enabling the air conditioner to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.
