Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an indoor air conditioning unit. Background Technology

[0002] In the assembly structure of an air conditioner indoor unit, the indoor heat exchanger is usually placed on the base. Generally, the industry uses left end plate, right end plate and front edge plate to limit the indoor heat exchanger, so that it is connected to the base and finally the indoor heat exchanger is fixed in the preset installation position of the base.

[0003] However, as air conditioner indoor units become smaller, there is a need for more compact indoor heat exchangers with higher heat exchange efficiency. These indoor heat exchangers, designed to fit compact spaces, typically have thinner copper tube walls to reduce space occupation, and the auxiliary support structure is also simplified, resulting in relatively weaker overall structural strength.

[0004] However, during the transportation of indoor units, they inevitably encounter external impacts such as bumps and drops. At this time, the shortcomings of the existing base structure become increasingly apparent. The current indoor unit relies solely on the end plate for fixation, which cannot provide comprehensive and effective restraint for the long and insufficiently rigid indoor heat exchanger. This makes it difficult to resist the external forces during transportation, leading to problems such as displacement and deformation of the indoor heat exchanger. Once the indoor heat exchanger is deformed, it not only disrupts its relative positional relationship with other components such as the indoor unit's fan and ducts, but also directly affects heat exchange efficiency and airflow path, thus severely weakening the normal performance of the air conditioner's indoor unit. In extreme cases, it may even cause the indoor unit to malfunction. Utility Model Content

[0005] This application provides an indoor air conditioning unit, the purpose of which is to achieve auxiliary limiting by setting limiting ribs in the water receiving tray, thereby ensuring that the indoor heat exchanger is stably installed on the base and avoiding displacement or deformation of the indoor heat exchanger due to bumps or drops during transportation.

[0006] To achieve the above objectives, this application adopts the following technical solution: Firstly, an indoor air conditioning unit is provided, comprising: The outer casing is provided with an air outlet, from which airflow is discharged; An indoor heat exchanger, wherein the indoor heat exchanger is disposed within the outer casing; A water collection tray is provided on the side of the indoor heat exchanger facing the ground; the water collection tray is used to collect the condensate generated by the indoor heat exchanger in cooling mode. The water receiving tray includes: Water tray body; A leading edge plate is disposed on the side of the water receiving tray body near the air outlet, and the leading edge plate extends along the length of the indoor heat exchanger. A plurality of first limiting ribs are provided, each first limiting rib being spaced apart along the length direction of the indoor heat exchanger; the first limiting ribs are attached to the side of the indoor heat exchanger near the air outlet, and the first limiting ribs are used to prevent the indoor heat exchanger from moving in the direction of approaching or moving away from the air outlet. A sealing rib is provided on the side of the first limiting rib away from the front edge plate. The sealing rib extends along the length of the indoor heat exchanger and fits against the side of the indoor heat exchanger facing the water receiving tray. The sealing rib is used to isolate the internal space of the air duct of the indoor air conditioning unit from the external space. The second limiting rib is disposed on the side of the sealing rib away from the first limiting rib, and the second limiting rib extends along the length direction of the indoor heat exchanger.

[0007] Secondly, an air conditioner indoor unit is provided, comprising: The outer casing is provided with an air outlet, from which airflow is discharged; An indoor heat exchanger, wherein the indoor heat exchanger is disposed within the outer casing; A water collection tray is provided on the side of the indoor heat exchanger facing the ground; the water collection tray is used to collect the condensate generated by the indoor heat exchanger in cooling mode. The water receiving tray includes: Water tray body; A leading edge plate is disposed on the side of the water receiving tray body near the air outlet, and the leading edge plate extends along the length direction of the indoor heat exchanger; a plurality of first limiting ribs are provided on the leading edge plate, and each first limiting rib is spaced apart along the length direction of the indoor heat exchanger; the first limiting ribs are attached to the side of the indoor heat exchanger near the air outlet, and the first limiting ribs are used to prevent the indoor heat exchanger from moving in the direction of approaching or moving away from the air outlet. A sealing rib is provided on the side of the first limiting rib away from the front edge plate. The sealing rib extends along the length of the indoor heat exchanger and fits against the side of the indoor heat exchanger facing the water receiving tray. The sealing rib is used to isolate the internal space of the air duct of the indoor air conditioning unit from the external space. The second limiting rib is disposed on the side of the sealing rib away from the first limiting rib, and the second limiting rib extends along the length direction of the indoor heat exchanger.

[0008] In the above embodiments, this application adds several first limiting ribs arranged at intervals along the length of the indoor heat exchanger on the base water receiving tray of the air conditioner indoor unit. This can effectively limit the indoor heat exchanger placed on the base, preventing the indoor heat exchanger from moving in the direction closer to or away from the air outlet due to bumps or drops during transportation. This avoids displacement or deformation of the indoor heat exchanger and ensures the structural integrity and subsequent performance of the indoor heat exchanger.

[0009] In addition, this application has a sealing rib extending along the length of the indoor heat exchanger on the water receiving tray, and the sealing rib is located on the side of the first limiting rib away from the front edge plate. This can effectively isolate the internal space of the air duct of the air conditioner indoor unit from the external space, avoid or reduce the crossflow of air inside and outside the air duct, thereby preventing the heat exchange air inside the air duct from mixing with the untreated air outside. This ensures that all the air drawn in by the fan is heat-exchanged by the indoor heat exchanger before entering the air duct, ensuring the heat exchange efficiency of the air conditioner indoor unit. At the same time, it can also reduce the abnormal noise caused by air crossflow and improve the user experience of the indoor unit.

[0010] In addition, this application also provides a second limiting rib on the water receiving tray, located on the side of the sealing rib away from the first limiting rib and extending along the length of the indoor heat exchanger. The second limiting rib can form a bidirectional limiting cooperation with the first limiting rib, constraining the indoor heat exchanger from different positions, effectively limiting the movement of the indoor heat exchanger in the direction perpendicular to the mounting wall. Compared with the unidirectional limiting of the first limiting rib alone, this double limiting structure can greatly improve the installation stability of the indoor heat exchanger on the base, further avoiding displacement and deformation of the indoor heat exchanger during transportation or use.

[0011] In some embodiments, the first limiting rib is connected to the side of the front edge plate facing the indoor heat exchanger.

[0012] In the above embodiments, this application connects the first limiting rib to the side of the front edge plate facing the indoor heat exchanger. The structural strength of the front edge plate itself can provide stable support for the first limiting rib, effectively dispersing the stress generated by the first limiting rib when subjected to the compression or external force of the indoor heat exchanger. This prevents the first limiting rib from bending or breaking due to excessive force at a single point, significantly improving the overall structural strength of the first limiting rib and ensuring that it can continuously and stably limit the indoor heat exchanger, preventing the indoor heat exchanger from shaking or deforming.

[0013] In some embodiments, the first limiting rib includes a limiting portion and a connecting portion. The limiting portion is disposed on the side of the water receiving pan body facing the indoor heat exchanger, and the connecting portion is disposed on the side of the limiting portion away from the indoor heat exchanger. The connecting portion is connected to the front edge plate.

[0014] In the above embodiments, the first limiting rib is designed to include a limiting part and a connecting part. The connecting part is located on the side of the limiting part away from the indoor heat exchanger and is connected to the front edge plate. On the one hand, the limiting part can limit the indoor heat exchanger by fitting with the indoor heat exchanger. On the other hand, the connecting part can play a structural support role between the limiting part and the front edge plate, effectively enhancing the overall strength of the limiting part and preventing the limiting part from breaking or deforming when subjected to the squeezing of the indoor heat exchanger or external transportation force, thus ensuring that the limiting function is stable and reliable.

[0015] In some embodiments, the side of the limiting portion facing the indoor heat exchanger is parallel to the side of the front edge plate facing the indoor heat exchanger, and the connecting portion is perpendicular to the limiting portion.

[0016] In the above embodiments, this application makes the limiting part of the first limiting rib parallel to the front edge plate, and the connecting part perpendicular to the limiting part. This vertical connection structure makes the supporting force of the connecting part on the limiting part more uniform, so that the first limiting rib can obtain the maximum load-bearing strength and deformation resistance in the overall structure, thereby more effectively resisting the external forces generated by the indoor heat exchanger during transportation or use, further improving the limiting effect on the indoor heat exchanger, and reducing the risk of displacement and deformation of the indoor heat exchanger.

[0017] In some embodiments, the vertical distance from the connection point between the side of the connecting portion away from the water receiving tray body and the front edge plate to the water receiving tray body is less than the vertical distance from the side of the front edge plate away from the water receiving tray body to the water receiving tray body.

[0018] In the above embodiments, the top of the connection part of this application is lower than the height of the top of the front edge plate at the connection point. This design can guide the condensate droplets generated by the indoor heat exchanger to flow into the water receiving tray after the first limiting rib, and prevent the condensate droplets from flowing directly along the connection part to the front edge plate and eventually submerging the upper edge of the front edge plate, which would cause the indoor unit to leak.

[0019] In some embodiments, the spacing between any two adjacent first limiting ribs is equal.

[0020] In the above embodiments, this application clearly states that the spacing between two adjacent first limiting ribs is equal. This uniformly spaced arrangement allows each first limiting rib to evenly distribute the compressive force generated when the indoor heat exchanger moves or is subjected to force, avoiding premature damage due to concentrated force on some first limiting ribs. At the same time, it ensures that each position of the indoor heat exchanger along the length direction can obtain balanced limiting constraints, further improving the stability and reliability of limiting the indoor heat exchanger, and better preventing displacement and deformation of the indoor heat exchanger.

[0021] In some embodiments, the number of sealing ribs is at least two, and each sealing rib is spaced apart along the length of the indoor heat exchanger.

[0022] In the above embodiments, this application sets the number of sealing ribs to at least two, and each sealing rib is spaced apart along the length of the indoor heat exchanger. While ensuring the insulation effect, it also provides a channel for condensate to flow out, preventing all cold water from flowing to both sides of the sealing ribs and causing water leakage in the drip tray.

[0023] In some embodiments, the second limiting rib is provided with a plurality of reinforcing ribs on the side near the sealing rib and / or on the side away from the sealing rib, and each of the reinforcing ribs is spaced apart along the length direction of the indoor heat exchanger.

[0024] In the above embodiments, this application provides a plurality of reinforcing ribs arranged at intervals along the length of the indoor heat exchanger on the side of the second limiting rib near the sealing rib and / or the side away from the sealing rib. The reinforcing ribs can effectively enhance the overall structural strength and deformation resistance of the second limiting rib, prevent the second limiting rib from bending or breaking when subjected to the squeezing of the indoor heat exchanger or external impact, and ensure that the second limiting rib can continuously and stably cooperate with the first limiting rib to limit the indoor heat exchanger, further ensuring the installation stability of the indoor heat exchanger and the normal use of the indoor unit.

[0025] In some embodiments, the spacing between any two adjacent reinforcing ribs is equal.

[0026] In the above embodiments, this application sets the spacing between any two adjacent reinforcing ribs to be equal, so that each reinforcing rib is evenly distributed on the second limiting rib. When the indoor heat exchanger moves or is subjected to force due to transportation bumps, external impacts, etc., the evenly distributed reinforcing ribs can synchronously and evenly bear the compressive force transmitted by the second limiting rib, avoiding excessive stress concentration on some reinforcing ribs due to uneven spacing, and effectively preventing individual reinforcing ribs from breaking or deforming due to overload.

[0035] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0036] In the assembly structure of an air conditioner indoor unit, the installation stability of the indoor heat exchanger directly affects the heat exchange efficiency and operational reliability of the equipment. It is typically placed on a base. To initially secure the indoor heat exchanger, the industry commonly uses left and right end plates to connect both sides of the heat exchanger to the base, and uses a front edge plate for limiting its position. This method firmly confines the indoor heat exchanger to its preset installation position on the base. This fixing method can meet basic usage requirements in traditional indoor heat exchanger applications.

[0037] However, as air conditioner indoor units become increasingly smaller, higher demands are placed on the spatial adaptability and heat exchange efficiency of indoor heat exchangers. Back-tube evaporators, with their core advantages of high heat exchange efficiency and compact structure, are better suited to the spatial layout of smaller indoor units and have gradually become an important choice to meet these needs. However, these indoor heat exchangers, designed for compact spaces, typically have thinner copper tube walls to reduce space occupation, and their auxiliary support structures are also simplified, resulting in relatively weaker overall structural strength. During the transportation of indoor units, they inevitably encounter external impacts such as bumps and drops. In such cases, the original base structure, which relies solely on end plates for fixation, cannot form a good fit with the back-tube indoor heat exchanger. The end plates can only constrain the sides of the indoor heat exchanger and cannot cover the middle area of ​​the long, narrow structure of the back-tube indoor heat exchanger, failing to provide comprehensive support. This leads to deformation problems such as bending in the middle area and pipe displacement under the influence of external forces during transportation.

[0038] If a back-tube indoor heat exchanger deforms, it will not only disrupt the relative position of the back-tube pipes with the indoor unit's internal fan and duct, causing the airflow path to deviate and directly reducing heat exchange efficiency; it may also cause poor refrigerant flow due to pipe deformation, or even lead to pipe damage and leakage. This will not only severely weaken the normal performance of the air conditioner's indoor unit, but in extreme cases, it may also cause the indoor unit to become completely inoperable, posing significant risks to the production and use processes.

[0039] Based on this, this application proposes an indoor air conditioning unit that uses limiting ribs in the drip tray 110 to achieve auxiliary limiting, thereby ensuring that the indoor heat exchanger 300 is stably installed on the base 100 and preventing deformation of the indoor heat exchanger 300 due to bumps or drops during transportation. At the same time, it ensures that the drip tray 110 can still effectively collect the condensate from the indoor heat exchanger 300, allowing the indoor air conditioning unit to operate normally.

[0040] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0041] As attached Figures 1 to 10 As shown in an illustrative embodiment of this application, the indoor unit of the air conditioner includes a housing 200, which is provided with an air outlet from which airflow is discharged.

[0042] In some embodiments, an openable air guide plate 210 is provided at the air outlet, and the opening degree of the air outlet and the direction of airflow discharge are controlled by controlling the opening and closing angle of the air guide plate 210.

[0043] In some embodiments, the indoor unit of the air conditioner includes an indoor heat exchanger 300, which is disposed within the outer casing 200. The indoor heat exchanger 300 is the core heat exchange component of the indoor unit, and its structure mainly consists of heat exchange pipes and fins. The indoor heat exchanger 300 relies on refrigerant to achieve heat exchange. In cooling mode, after the low-temperature, low-pressure liquid refrigerant enters the indoor heat exchanger 300, it absorbs heat from the indoor air flowing across its surface and evaporates into a gaseous state, thereby lowering the air temperature. In the heating mode of a heat pump air conditioner, the gaseous refrigerant condenses within the indoor heat exchanger 300 and releases heat, thereby heating the air.

[0044] In some embodiments, the indoor unit of the air conditioner includes a fan disposed within the housing 200. The fan is mainly used to draw indoor air into the indoor unit, where it undergoes heat exchange in the indoor heat exchanger 300, and then the treated air is pushed into the air duct and discharged from the air outlet.

[0045] In some embodiments, the indoor unit of the air conditioner includes a base 100 disposed within the housing 200.

[0046] In some embodiments, the projection of the base 100 along the length of the indoor unit of the air conditioner is generally L-shaped; the base 100 extends from the side of the housing 200 near the mounting wall to the side of the housing 200 near the ground.

[0047] In some embodiments, the indoor heat exchanger 300 is disposed on the base 100, the rear and lower sides of the indoor heat exchanger 300 are wrapped by the base 100, and the indoor heat exchanger 300 is disposed between the base 100 and the outer casing 200.

[0048] In some embodiments, the base 100 includes a water collection tray 110, which is disposed on the side of the indoor heat exchanger 300 facing the ground. Specifically, the water collection tray 110 is disposed in front of and below the indoor heat exchanger 300, and there is a certain distance between the water collection tray 110 and the indoor heat exchanger 300. The water collection tray 110 is used to collect the condensate generated by the indoor heat exchanger 300 in the cooling mode.

[0049] Furthermore, the length of the water receiving tray 110 is greater than the length of the indoor heat exchanger 300, so as to better collect the condensate generated by the indoor heat exchanger 300.

[0050] It is worth noting that, in this application, the lower / bottom of the air conditioner indoor unit and its internal components refers to the side of the air conditioner indoor unit that is close to the ground after assembly, the upper / top of the air conditioner indoor unit and its internal components refers to the side of the air conditioner indoor unit that is away from the ground after assembly, the rear of the air conditioner indoor unit and its internal components refers to the side of the air conditioner indoor unit that is away from the air outlet after assembly, and the front of the air conditioner indoor unit and its internal components refers to the side of the air conditioner indoor unit that is located at the air outlet after assembly. The same applies throughout the text and will not be repeated here.

[0051] In some embodiments, the water collection tray 110 includes a water collection tray body 111, which is disposed on the side of the indoor heat exchanger 300 facing the ground. Specifically, the water collection tray body 111 is disposed in front of and below the indoor heat exchanger 300, and a certain distance is spaced between the water collection tray body 111 and the indoor heat exchanger 300. The water collection tray body 111 is used to collect the condensate generated by the indoor heat exchanger 300 in the cooling mode.

[0052] In some embodiments, the drip tray 110 includes a front edge plate 112, which is disposed on the side of the drip tray body 111 near the air outlet, i.e., on the front side of the drip tray body 111. The front edge plate 112 extends from one end of the drip tray body 111 to the other end along the length direction of the indoor heat exchanger 300. The front edge plate 112 is used to prevent condensate from leaking out from the front side of the drip tray body 111, which would cause the air outlet to leak.

[0053] Furthermore, the water receiving tray body 111 and the front edge plate 112 are an integral structure.

[0054] In some embodiments, the water receiving tray 110 includes a plurality of first limiting ribs 120, the first limiting ribs 120 being disposed on the side of the water receiving tray body 111 near the indoor heat exchanger; each first limiting rib 120 is spaced apart along the length direction of the indoor heat exchanger 300.

[0055] In some embodiments, the first limiting rib 120 is attached to the side of the indoor heat exchanger 300 near the air outlet. Specifically, the first limiting rib 120 is attached to the lower front of the indoor heat exchanger 300. The first limiting rib 120 is used to prevent the indoor heat exchanger 300 from moving in the direction of approaching or moving away from the air outlet.

[0056] Furthermore, the water receiving tray 110 and the first limiting rib 120 are an integral structure.

[0057] In some embodiments, a plurality of first limiting ribs 120 are provided on the front edge plate 112, and each first limiting rib 120 is spaced apart along the length direction of the indoor heat exchanger 300; the first limiting rib 120 is attached to the side of the indoor heat exchanger 300 near the air outlet, specifically, the first limiting rib 120 is attached to the lower front of the indoor heat exchanger 300, and the first limiting rib 120 is used to prevent the indoor heat exchanger 300 from moving in the direction of approaching or moving away from the air outlet.

[0058] In the above embodiments, this application adds a plurality of first limiting ribs 120 arranged at intervals along the length direction of the indoor heat exchanger 300 on the water receiving tray 110 of the base 100 of the air conditioner indoor unit, and the first limiting ribs 120 are connected to the front edge plate 112 of the water receiving tray 110 near the air outlet. This can effectively limit the indoor heat exchanger 300 placed on the base 100, and prevent the indoor heat exchanger 300 from moving in the direction close to or away from the air outlet due to bumps or drops during the transportation of the indoor unit. This avoids displacement or deformation of the indoor heat exchanger 300 and ensures the structural integrity and subsequent performance of the indoor heat exchanger 300.

[0059] In some embodiments, the first limiting rib 120 is connected to the side of the front edge plate 112 facing the indoor heat exchanger 300.

[0060] In the above embodiments, the first limiting rib 120 is connected to the side of the front edge plate 112 facing the indoor heat exchanger 300. The structural strength of the front edge plate 112 itself can provide stable support for the first limiting rib 120, effectively dispersing the stress generated by the first limiting rib 120 when subjected to the compression or transportation force of the indoor heat exchanger 300. This avoids the first limiting rib 120 from bending or breaking due to excessive force at a single point, significantly improving the overall structural strength of the first limiting rib 120, and ensuring that it can continuously and stably limit the indoor heat exchanger 300, preventing the indoor heat exchanger 300 from shaking or deforming.

[0061] In some embodiments, the first limiting rib 120 includes a limiting part 121 and a connecting part 122. The limiting part 121 is disposed on the side of the water receiving pan body 111 facing the indoor heat exchanger 300, and the connecting part 122 is disposed on the side of the limiting part 121 away from the indoor heat exchanger 300. The connecting part 122 is connected to the front edge plate 112, and both the limiting part 121 and the connecting part 122 are connected to the side of the water receiving pan body 111 away from the ground.

[0062] In the above embodiments, the first limiting rib 120 is designed to include a limiting part 121 and a connecting part 122. The connecting part 122 is located on the side of the limiting part 121 away from the indoor heat exchanger 300 and is connected to the front edge plate 112. On the one hand, the limiting part 121 can limit the indoor heat exchanger 300 by fitting with the indoor heat exchanger 300. On the other hand, the connecting part 122 can play a structural support role between the limiting part 121 and the front edge plate 112, effectively enhancing the overall strength of the limiting part 121 and preventing the limiting part 121 from breaking or deforming when subjected to the squeezing of the indoor heat exchanger 300 or external transportation force, thus ensuring that the limiting function is stable and reliable.

[0063] In some embodiments, the side of the limiting portion 121 facing the indoor heat exchanger 300 is parallel to the side of the front edge plate 112 facing the indoor heat exchanger 300, and the connecting portion 122 is perpendicular to the limiting portion 121. Specifically, the first limiting rib 120 has a T-shaped structure.

[0064] In the above embodiments, this application makes the limiting part 121 of the first limiting rib 120 parallel to the front edge plate 112, and the connecting part 122 perpendicular to the limiting part 121. This vertical connection structure allows the supporting force of the connecting part 122 on the limiting part 121 to be more uniform, so that the first limiting rib 120 can obtain the maximum load-bearing strength and deformation resistance in the overall structure, thereby more effectively resisting the external forces generated by the indoor heat exchanger 300 during transportation or use, further improving the limiting effect on the indoor heat exchanger 300, and reducing the risk of displacement and deformation of the indoor heat exchanger 300.

[0065] In some embodiments, the vertical distance from the connection point of the connecting portion 122 away from the water receiving tray body 111 and the connection point of the front edge plate 112 to the water receiving tray body 111 is less than the vertical distance from the side of the front edge plate 112 away from the water receiving tray body 111 to the water receiving tray body 111.

[0066] In the above embodiment, the top of the connection part 122 is lower than the top of the front edge plate 112 at the connection point. This design can guide the condensate droplets generated by the indoor heat exchanger 300 into the water receiving tray body 111 after the first limiting rib 120, and prevent the condensate droplets from flowing directly along the connection part 122 to the front edge plate 112 and eventually overflowing the upper edge of the front edge plate 112, which would cause the indoor unit to leak.

[0067] In some embodiments, a notch 122a is provided on the side of the connecting portion 122 away from the ground and close to the front edge plate 112, and the notch 122a is located above the front of the connecting portion 122.

[0068] In the above embodiment, a notch 122a is provided on the side of the connecting portion 122 of the first limiting rib 120 away from the ground and close to the front edge plate 112. The notch 122a can guide the condensate droplets generated by the indoor heat exchanger 300 to flow into the water receiving tray body 111 after the first limiting rib 120, avoiding the condensate droplets from flowing directly along the connecting portion 122 to the front edge plate 112 and eventually overflowing the upper edge of the front edge plate 112, which would cause the indoor unit to leak. In addition, the notch 122a can reduce the material usage of the connecting portion 122 while ensuring the connection strength between the connecting portion 122 and the limiting portion 121 and the front edge plate 112, without affecting the overall limiting function of the first limiting rib 120, thereby reducing the weight of the first limiting rib 120. This reduces the overall manufacturing cost of the base 100 and helps to reduce the total weight of the indoor unit, which is in line with the design trend of lightweight indoor units.

[0069] In some embodiments, the corners of the limiting portion 121 and the connecting portion 122 are rounded to avoid stress concentration.

[0070] In some embodiments, the spacing between any two adjacent first limiting ribs 120 is equal.

[0071] In some embodiments, there are a total of six first limiting ribs 120.

[0072] In the above embodiments, this application clearly states that the spacing between two adjacent first limiting ribs 120 is equal. This uniformly spaced arrangement allows each first limiting rib 120 to evenly distribute the compressive force generated when the indoor heat exchanger 300 moves or is subjected to force, avoiding premature damage due to concentrated force on some first limiting ribs 120. At the same time, it ensures that the indoor heat exchanger 300 can obtain balanced limiting constraints at all positions along the length direction, further improving the stability and reliability of limiting the indoor heat exchanger 300, and better preventing displacement and deformation of the indoor heat exchanger 300.

[0073] In some embodiments, the water receiving tray 110 further includes a sealing rib 130, which is disposed on the water receiving tray body 111. The sealing rib 130 is disposed on the side of the first limiting rib 120 away from the front edge plate 112, that is, the sealing rib 130 is disposed behind the first limiting rib 120. The sealing rib 130 is spaced apart from the first limiting rib 120 by a certain distance. The sealing rib 130 extends along the length direction of the indoor heat exchanger 300, and the length of the sealing rib 130 is slightly less than the length of the indoor heat exchanger 300. The two sides of the sealing rib 130 are spaced apart from the condensate baffles on both sides of the water receiving tray body 111 by a certain distance to facilitate the passage of condensate. The sealing rib 130 is attached to the side of the indoor heat exchanger 300 facing the water receiving tray 110. The sealing rib 130 is used to isolate the internal space of the air duct of the indoor air conditioning unit from the external space.

[0074] Specifically, the sealing rib 130 is a rectangular plate.

[0075] Furthermore, the sealing rib 130 and the water receiving tray 110 are integrally formed.

[0076] Furthermore, all corners of the sealing rib 130 are rounded to avoid stress concentration.

[0077] In the above embodiments, the present application provides a sealing rib 130 extending along the length of the indoor heat exchanger 300 on the water receiving tray 110, and the sealing rib 130 is located on the side of the first limiting rib 120 away from the front edge plate 112. It can effectively isolate the internal space of the air duct of the air conditioner indoor unit from the external space, avoid or reduce the crossflow of air inside and outside the air duct, thereby preventing the heat exchange air inside the air duct from mixing with the untreated air outside, so that all the air drawn in by the fan is heat exchanged by the indoor heat exchanger 300 before entering the air duct, ensuring the heat exchange efficiency of the air conditioner indoor unit, and at the same time reducing the abnormal noise caused by air crossflow, improving the user experience of the indoor unit.

[0078] In some embodiments, the number of sealing ribs 130 is at least two, and each sealing rib 130 is spaced apart along the length direction of the indoor heat exchanger 300.

[0079] Preferably, the number of sealing ribs 130 is two.

[0080] In the above embodiments, the number of sealing ribs 130 is set to at least two, and each sealing rib 130 is spaced apart along the length of the indoor heat exchanger 300. While ensuring the isolation effect, it reserves a channel for condensate to flow out, and avoids all the cold water flowing to both sides of the sealing ribs 130, which would cause the condensate water level to rise and thus cause the water tray 110 to leak.

[0081] In some embodiments, the water receiving tray 110 further includes a second limiting rib 140, which is disposed on the water receiving tray body 111. The second limiting rib 140 is disposed on the side of the sealing rib 130 away from the first limiting rib 120, that is, behind the sealing rib 130. The second limiting rib 140 is spaced a certain distance from the sealing rib 130, and the second limiting rib 140 extends along the length direction of the indoor heat exchanger 300.

[0082] In some embodiments, the main body of the second limiting rib 140 is a rectangular plate.

[0083] Furthermore, all corners of the second limiting rib 140 are rounded to avoid stress concentration.

[0084] In the above embodiments, this application provides a second limiting rib 140 on the water receiving tray 110, located on the side of the sealing rib 130 away from the first limiting rib 120 and extending along the length direction of the indoor heat exchanger 300. The second limiting rib 140 can form a bidirectional limiting cooperation with the first limiting rib 120, constraining the indoor heat exchanger 300 from different positions, effectively limiting the movement of the indoor heat exchanger 300 along the direction perpendicular to the mounting wall. Compared with the unidirectional limiting of the first limiting rib 120 alone, this double limiting structure can greatly improve the installation stability of the indoor heat exchanger 300 on the base 100, and further avoid displacement and deformation of the indoor heat exchanger 300 during transportation or use.

[0085] In some embodiments, the second limiting rib 140 is provided with a plurality of reinforcing ribs 141 on the side near the sealing rib 130, and each reinforcing rib 141 is spaced apart along the length direction of the indoor heat exchanger 300.

[0086] In some embodiments, the second limiting rib 140 is provided with a plurality of reinforcing ribs 141 on the side away from the sealing rib 130, and each reinforcing rib 141 is spaced apart along the length direction of the indoor heat exchanger 300.

[0087] In some embodiments, the second limiting rib 140 is provided with a plurality of reinforcing ribs 141 on both the side near the sealing rib 130 and the side away from the sealing rib 130, and each reinforcing rib 141 is spaced apart along the length direction of the indoor heat exchanger 300.

[0088] In some embodiments, the number of reinforcing ribs 141 on the side of the second limiting rib 140 near the sealing rib 130 and / or on the side away from the sealing rib 130 is ten.

[0089] In some embodiments, the spacing between any two adjacent reinforcing ribs 141 is equal, allowing each reinforcing rib 141 to be uniformly distributed on the second limiting rib 140. When the indoor heat exchanger 300 moves or is subjected to force due to transportation bumps, external impacts, etc., the uniformly distributed reinforcing ribs 141 can synchronously and evenly bear the compressive force transmitted by the second limiting rib 140, avoiding excessive stress concentration on some reinforcing ribs 141 due to uneven spacing, and effectively preventing individual reinforcing ribs 141 from breaking or deforming due to overload.

[0090] In the above embodiments, this application provides a plurality of reinforcing ribs 141 arranged at intervals along the length of the indoor heat exchanger 300 on the side of the second limiting rib 140 near the sealing rib 130 and / or away from the sealing rib 130. The reinforcing ribs 141 can effectively enhance the overall structural strength and deformation resistance of the second limiting rib 140, prevent the second limiting rib 140 from bending or breaking when subjected to the squeezing of the indoor heat exchanger 300 or external impact, and ensure that the second limiting rib 140 can continuously and stably cooperate with the first limiting rib 120 to limit the indoor heat exchanger 300, further ensuring the installation stability of the indoor heat exchanger 300 and the normal use of the indoor unit.

[0091] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
