Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to an air conditioner indoor unit. Background Art

[0002] With the continuous advancement of commercial air conditioning and the ever-changing market demand, the design and manufacturing of commercial air conditioners are increasingly pursuing high efficiency and low cost. To save material costs, the diameter of the copper tubes in the heat exchanger has been reduced from Φ7 to Φ5, and the wall thickness has also been reduced accordingly.

[0003] Heat exchangers are typically mounted to the housing at both ends using mounting hardware. However, due to the reduced wall thickness of the copper tubes in the heat exchanger, the overall structural strength of the heat exchanger is reduced. Mounting the heat exchanger to the housing using only mounting hardware may result in a lack of adequate structural support. Consequently, during transportation of the air conditioner indoor unit, vibration or impact may cause irreversible deformation in the central area of ​​the heat exchanger, affecting its appearance and potentially causing refrigerant leaks.

[0004] This problem is more significant especially for large air conditioners because the heat exchanger is longer in size. Utility Model Content

[0005] An embodiment of the present application discloses an air-conditioning indoor unit, in which a support assembly configured to provide effective support for a heat exchanger is capable of preventing the heat exchanger from deforming under impact, thereby ensuring the working performance of the air-conditioning indoor unit.

[0006] To achieve the above objectives, the present invention discloses an air conditioner indoor unit, comprising:

[0007] A shell body is provided with an air inlet and an air outlet that are connected to each other;

[0008] The housing consists of a top plate and a bottom plate:

[0009] a top plate, located on the top of the shell;

[0010] The bottom plate and the top plate are arranged opposite to each other along the height direction of the air conditioner indoor unit;

[0011] A heat exchanger is disposed in the housing, the heat exchanger extending along the length direction of the housing and along the height direction of the air conditioner indoor unit, the heat exchanger being located between the top plate and the bottom plate;

[0012] A water receiving pan is provided on the bottom plate, and the bottom end of the heat exchanger abuts against the water receiving pan;

[0013] A centrifugal fan is installed in the housing. The centrifugal fan can guide the indoor air from the air inlet into the housing, and send the air out of the housing through the air outlet after heat exchange in the heat exchanger.

[0014] A support assembly is provided on the shell, and is used to support the heat exchanger;

[0015] The support components include:

[0016] A first support member is provided on the top plate, the first support member extends along the length direction, and the first support member includes a support surface, and the support surface is used to support the top end of the heat exchange;

[0017] The limiting member is formed in an outwardly convex manner on the supporting surface. The limiting member is located on the side of the heat exchanger away from the top plate. The limiting member can limit the heat exchanger.

[0018] Thus, the air conditioner indoor unit provided in the embodiment of the present application is provided with a support assembly that extends along the length of the housing. The support assembly includes a first support member and a stop member. The first support member can fully support the heat exchanger along the length of the housing. In this way, if the heat exchanger is subjected to external impact, the middle portion of the heat exchanger will not be easily deformed due to lack of support. The stop member can limit the heat exchanger to prevent the heat exchanger from falling from the first support member in the event of a large displacement, causing excessive deformation of the heat exchanger, thereby reducing the risk of refrigerant leakage and ensuring the performance of the heat exchanger.

[0019] The present application also discloses an air conditioner indoor unit, comprising:

[0020] A shell body is provided with an air inlet and an air outlet that are connected to each other;

[0021] The housing consists of a top plate and a bottom plate:

[0022] a top plate, located on the top of the shell;

[0023] The bottom plate and the top plate are arranged opposite to each other along the height direction of the air conditioner indoor unit;

[0024] A heat exchanger is disposed in the housing, the heat exchanger extending along the length direction of the housing and along the height direction of the air conditioner indoor unit, the heat exchanger being located between the top plate and the bottom plate;

[0025] A centrifugal fan is installed in the housing. The centrifugal fan can guide the indoor air from the air inlet into the housing, and send the air out of the housing through the air outlet after heat exchange in the heat exchanger.

[0026] A water receiving pan is provided on the bottom plate, and the bottom end of the heat exchanger abuts against the water receiving pan;

[0027] A support assembly is provided on the shell, and is used to support the heat exchanger;

[0028] The support components include:

[0029] A first support member is provided on the top plate, the first support member extends along the length direction, and the first support member includes a support surface, and the support surface is used to support the top end of the heat exchanger;

[0030] The limiting member is formed in an outward protrusion on the supporting surface. The limiting member is located on the side of the heat exchanger away from the top plate. The limiting member is used to limit the heat exchanger from sliding along the supporting surface.

[0031] In a possible implementation, the support surface of the first support member is tilted and forms an angle with the top plate. Along the tilt direction of the support surface, the length L1 of the limit member satisfies: L1>8mm, L1<20mm.

[0032] In this way, L1>8mm ensures the structural strength of the limiter, effectively limiting the heat exchanger. If L1 is too small, the limiter may deform or be damaged due to excessive force, thus losing its ability to limit the heat exchanger. L1<20mm can prevent the limiter from being too long and interfering with other structural components within the shell.

[0033] In a possible implementation, the first support member further includes:

[0034] An isolation portion is formed at one end of the first support member close to the top plate, and is located between the top plate and the heat exchanger;

[0035] The isolation portion located between the top plate and the heat exchanger can reduce the amount of heat or cold transferred from the heat exchanger to the top plate. This can reduce or prevent condensation caused by the top plate's low temperature, especially when the air conditioner's indoor unit is in cooling mode.

[0036] In a possible implementation, the isolation portion protrudes from the support surface, and along the inclination direction of the support surface, the limiting member and the isolation portion are respectively located at two ends of the support surface.

[0037] In this way, the isolation part and the limiting part are respectively located at the two ends of the supporting surface, so that the first supporting member can not only limit and support the heat exchanger, but also insulate the heat exchanger from the top plate, making the structural parts of the air conditioner indoor unit more streamlined.

[0038] In a possible implementation, the limiting member and the supporting surface are connected by an arc transition.

[0039] By using a circular arc transition to connect the stopper and the support surface, the impact force can be more smoothly distributed near the contact point between the stopper and the support surface, thereby reducing the possibility of damage to the stopper. This not only extends the service life of the support assembly, but also ensures the overall performance and stability of the air conditioner indoor unit.

[0040] In a possible implementation, the first support member and the limiting member are an integrated structure; and / or

[0041] The first supporting member is a foam member, and the limiting member is a foam member.

[0042] In this way, the stopper and the first support member are constructed as an integral structure, eliminating the need for additional connectors or fixings between the first support member and the stopper, further improving the manufacturing efficiency of the support assembly. If the first support member is a foam member, the stopper can also be a foam member and be integrally molded with the first support member. This improves the molding efficiency of the stopper and the first support member and reduces the number of steps in the production process.

[0043] In a possible implementation, the first support member includes:

[0044] Embedded parts, embedded parts are set on the top plate;

[0045] The foam layer is covered on the embedded part, and the limiting part and the foam layer are an integrated structure.

[0046] In this way, the embedded component has a certain structural strength, providing a stable support base for the entire first support member. The embedded component is covered with a foam layer, and the limiter can be integrally formed with the foam layer. The limiter can be directly formed during the foam layer production process without the need for additional connectors or adhesives to fix it to the foam layer.

[0047] In one possible implementation, the air conditioner indoor unit further includes:

[0048] The liner is arranged on the supporting surface and is located between the supporting surface and the heat exchanger.

[0049] In this way, the gasket can effectively absorb and disperse the vibration and shock from the heat exchanger, further reducing the risk of damage to the fins and copper tubes of the heat exchanger.

[0050] In one possible implementation, the pad is a closed-cell sponge pad.

[0051] In this way, the closed-cell sponge gasket can effectively prevent condensed water dripping from the heat exchanger from dripping onto a position on the bottom plate where no water receiving pan is provided, thereby avoiding potential water leakage problems.

[0052] In one possible implementation, the shell further includes: a side panel connected to the top panel; the air conditioner indoor unit further includes: a second support member, or the second support member is connected to the side panel, and the second support member is connected to the end of the heat exchanger along the length direction.

[0053] In this way, the support assembly can not only provide structural support for the portion of the heat exchanger extending along the length direction, but the second support member can also provide structural support for the end of the heat exchanger, making the heat exchanger as a whole more stable and reliable during the operation of the air conditioner indoor unit.

[0054] In a possible implementation manner, the second support member is configured as a triangular structure.

[0055] In this way, since the triangular structure has relatively stable geometric characteristics, the load-bearing capacity and deformation resistance of the second support member can be improved, thereby further extending the service life of the heat exchanger and the entire air-conditioning indoor unit.

DETAILED DESCRIPTION

[0069] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0070] In this application, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0071] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0072] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0073] In addition, the terms "first," "second," etc. are primarily used to distinguish different devices, elements, or components, and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0074] With the continuous advancement of commercial air conditioning and evolving market demands, the design and manufacturing of commercial air conditioners are constantly striving for higher efficiency and lower costs. To save material costs, the diameter of the copper tubes in commercial air conditioner heat exchangers has been continuously reduced, gradually switching from the traditional Φ7 to Φ5, and the wall thickness of the copper tubes has also been reduced. While this structural change brings cost advantages, it also reduces the overall structural strength of the heat exchanger.

[0075] The end plates at each end of the heat exchanger are connected to the air conditioner indoor unit casing via triangular sheet metal to support the heat exchanger. This solution, which only supports the ends of the heat exchanger, results in a lack of necessary support in the middle of the heat exchanger. As a result, when subjected to significant impact or vibration, the middle of the heat exchanger is prone to permanent deformation. The entire heat exchanger may even move or fall, impacting other nearby components and causing safety hazards such as leakage. This problem is particularly prominent in large commercial air conditioners due to the longer size of the heat exchanger.

[0076] Based on this, the present application proposes an air-conditioning indoor unit, which comprehensively supports the heat exchanger through a supporting assembly, and the heat exchanger is not easily deformed, thereby ensuring the working performance and service life of the air-conditioning indoor unit.

[0077] In the embodiment of the present application, the air conditioner includes a compressor, a condenser, an evaporator, and a throttling component to perform the cooling or heating cycle of the air conditioner. The air conditioner can include an indoor unit and an outdoor unit. The compressor is usually installed in the outdoor unit, and the throttling component can be installed in the indoor unit 100 or the outdoor unit. When the air conditioner is in heating mode, the heat exchanger 20 in the indoor unit serves as the condenser, and the heat exchanger 20 in the outdoor unit serves as the evaporator. When the air conditioner is in cooling mode, the heat exchanger 20 in the indoor unit 100 serves as the evaporator, and the heat exchanger 20 in the outdoor unit serves as the condenser.

[0078] like Figure 1 and Figure 2 The figure shows a schematic structural diagram of an air conditioning indoor unit 100 provided in an embodiment of the present application. The air conditioning indoor unit 100 includes a housing 10. The housing 10 is a three-dimensional structure having a length direction, a width direction, and a height direction. The length direction, the width direction, and the height direction can be perpendicular or nearly perpendicular to each other. In other words, the angle formed between any two of the length direction, the width direction, and the height direction can be 87°, 89°, 90°, 91°, 93°, etc.

[0079] For example, the length direction of the housing 10 can be Figure 1 and Figure 2 The X direction in .

[0080] In some embodiments, as Figure 1 and Figure 2 As shown, the housing 10 is constructed as a cavity structure. A partition 107 is provided inside the housing 10, which can separate the cavity structure of the housing 10 into a heat exchange cavity 108 and a fan cavity 109. The heat exchange cavity 108 and the fan cavity 109 can be arranged in a horizontal direction.

[0081] In some embodiments, as Figure 2 As shown, the housing 10 may include an air inlet 101 . The fan cavity 109 is communicated with the air inlet 101 , and the air inlet 101 is formed on the portion of the housing 10 forming the fan cavity 109 .

[0082] In some embodiments, as Figure 1 As shown, the housing 10 may include an air outlet 102. The air outlet 102 is connected to the heat exchange chamber 108 and is formed on a portion of the housing 10 in the fan chamber 109. An air guide plate may be provided at the air outlet 102 to guide the air flow to the indoor environment.

[0083] In some embodiments, as Figure 1 and Figure 2 As shown, the housing 10 may include a top plate 103 and a bottom plate 104, which may be arranged opposite to each other along the height direction of the housing 10. A partition 107 is arranged between the top plate 103 and the bottom plate 104, and may separate the space between the top plate 103 and the bottom plate 104 into the heat exchange chamber 108 and the fan chamber 109.

[0084] In some embodiments, as Figure 3 As shown, the housing 10 may include a side panel 106 . The side panel 106 is connected between the top panel 103 and the bottom panel 104 and is located outside the partition panel 107 .

[0085] In some embodiments, as Figure 2 As shown, the air conditioner indoor unit 100 may further include a centrifugal fan 30. The centrifugal fan 30 may be disposed in a fan chamber 109. An air inlet 101 is formed on one side of the centrifugal fan 30, and indoor air may be sucked into the fan chamber 109 through the air inlet 101.

[0086] In order to blow the airflow driven by the centrifugal fan 30 toward the heat exchange chamber 108, a vent can be provided on the partition 107, and an air guide is provided on the periphery of the vent. The air guide can extend into the heat exchange chamber 108 to guide the airflow into the heat exchange chamber.

[0087] In some embodiments, the air conditioner indoor unit 100 may further include a motor. The motor may be disposed in the fan chamber 109. The motor is configured to drive the centrifugal fan 30 to rotate, so that the centrifugal fan 30 drives indoor air to flow into the fan chamber 109.

[0088] In some embodiments, as Figure 1 As shown, the air conditioner indoor unit 100 may also include a heat exchanger 20. The heat exchanger 20 comprises multiple copper tubes extending along the length of the housing 10. The copper tubes contain refrigerant. During the circulation process of the air conditioning system, the refrigerant is converted between liquid and gaseous states through the action of components such as the compressor, condenser, and expansion valve, thereby absorbing or releasing heat. Furthermore, to enhance heat exchange, the outer surface of the copper tubes is typically covered with one or more layers of fins. These fins increase the contact area with the air and improve the heat transfer rate.

[0089] In some embodiments, as Figure 3 As shown, the air conditioner indoor unit 100 may further include a water receiving pan 105. The water receiving pan 105 is disposed in the heat exchange chamber 108 and may be disposed on the bottom plate 104. The bottom end of the heat exchanger 20 may abut against the water receiving pan 105. The water receiving pan 105 is used to collect condensed water flowing from the heat exchanger 20.

[0090] In some embodiments, the water receiving tray 105 may be provided with a drain outlet, which can discharge the condensed water received by the water receiving tray 105 out of the housing 10 .

[0091] It should be noted that the bottom end of the heat exchanger 20 can be the end of the heat exchanger 20 close to the bottom plate 104. The heat exchanger 20 also has a length direction and a width direction. The length direction of the heat exchanger 20 is consistent with the length direction of the housing 10. The end of the heat exchanger 20 close to the bottom plate 104 along the width direction is the bottom end of the heat exchanger 20.

[0092] In some embodiments, as Figure 3 and Figure 4 As shown, the heat exchanger 20 can be placed in the heat exchange cavity 108. Typically, the heat exchanger 20 is tilted and disposed between the top plate 103 and the bottom plate 104 to increase the heat exchange area between the heat exchanger 20 and the air.

[0093] In some embodiments, as Figure 1 As shown, the air outlet 102 can be located on the side of the heat exchanger 20 away from the fan chamber 109. Under the action of the centrifugal fan 30, the indoor air enters the fan chamber 109 from the air inlet 101, then flows from the fan chamber 109 into the heat exchange chamber 108, passes through the heat exchanger 20 for heat exchange, and finally flows into the indoor environment through the air outlet 102.

[0094] In some embodiments, as Figure 1As shown, the air conditioner indoor unit 100 may further include a support assembly 40. The support assembly 40 is disposed on the housing 10 and is used to support the heat exchanger 20. That is, the support assembly 40 provides a supporting force to the heat exchanger 20 through the housing 10 to ensure that the heat exchanger 20 can be stably disposed in the heat exchange cavity 108 of the housing 10.

[0095] In some embodiments, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the support assembly 40 may include a first support member 401 . The first support member 401 is disposed on the top plate 103 .

[0096] Specifically, the first support member 401 can be a metal member or a foam member made of a foam material. In the case where the first support member 401 is a foam member, since the foam member is a lightweight structure, it can be directly bonded to the top plate 103 using adhesive, simplifying the installation process of the first support member 401.

[0097] In some embodiments, the first support member 401 extends along the length direction of the housing 10 , that is, the first support member 401 has a certain length along the length direction of the housing 10 .

[0098] In some embodiments, as Figure 7 and Figure 8 As shown, the first support member 401 includes a support surface 4011. The support surface 4011 is used to support the top end of the heat exchanger 20.

[0099] The top end of the heat exchanger 20 is opposite to the bottom end of the heat exchanger 20 along the width direction of the heat exchanger 20. The top end of the heat exchanger 20 has an extended length along the length direction of the shell. In this way, the top plate 103 can provide support force to the heat exchanger 20 through the first support surface 4011.

[0100] In some embodiments, the cross-section of the first support member 401 can be configured as a substantially triangular structure along the height direction of the air conditioner indoor unit 100. The support surface 4011 can be an inclined surface of the triangle, and the support surface 4011 can be arranged at an angle relative to the top plate 103. In this way, the support surface 4011 can be adapted to the heat exchanger 20 arranged at an angle between the top plate 103 and the bottom plate 104, thereby stably supporting the top end of the heat exchanger 20.

[0101] It can be understood that because both the first support member 401 and the heat exchanger 20 extend along the length of the housing 10, the first support member 401 can provide comprehensive support for the heat exchanger 20 along the length of the housing 10. Thus, the middle region of the heat exchanger 20 can be effectively supported by the first support member 401. Even if the air conditioner indoor unit 100 is subjected to impact and vibration during transportation and installation, the middle region of the heat exchanger 20 is not easily deformed or damaged due to the support of the first support member 401, thereby ensuring the operating performance of the heat exchanger 20.

[0102] Optionally, the first support member 401 may directly abut against the support surface 4011 , or indirectly abut against the support surface 4011 through other components.

[0103] In some embodiments, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the support assembly 40 may further include a limiting member 402 . The limiting member 402 is disposed on the supporting surface 4011 of the first support member 401 , and the limiting member 402 protrudes from the supporting surface 4011 .

[0104] The first support member 401 is used to support the heat exchanger 20. The stopper 402, disposed on the support surface 4011, is used to limit the position of the heat exchanger 20 supported on the counterbalancing surface. The stopper 402 can be in contact with the heat exchanger 20 to limit the position. Alternatively, a certain gap can be left between the stopper 402 and the heat exchanger 20. In the event of impact or vibration, the stopper 402 can contact the heat exchanger 20 to limit the heat exchanger 20.

[0105] In some embodiments, the stopper 402 can be disposed at the end of the support surface 4011 away from the top plate 103. In this way, even if the heat exchanger 20 is subjected to a large impact force and causes a certain displacement, the stopper 402 can limit the heat exchanger 20, preventing the heat exchanger 20 from moving toward the water receiving tray 105 and falling off the first support member 401 under the action of the large impact force, thereby reducing the risk of deformation of the heat exchanger 20 and refrigerant leakage.

[0106] As mentioned above, the air guide can extend into the heat exchange cavity 108. If the heat exchanger 20 falls from the first support member 401, it may interfere with the air guide, thereby creating the risk of deformation of the heat exchanger 20. The setting of the limit member 402 can prevent the heat exchanger 20 from falling from the first support member 401, thereby ensuring the stable installation of the heat exchanger.

[0107] In some embodiments, the stopper 402 may extend along the length of the housing 10 . In this way, the stopper 402 may be fully provided on the first support member 401 in the length direction of the housing 10 to further ensure that the heat exchanger 20 is stably supported by the support assembly 40 .

[0108] Optionally, when the first support member 401 is a metal member, the limiting member 402 may be a metal member, and the limiting member 402 may be welded to the first support member 401 .

[0109] Optionally, when the first support member 401 is a foam member made of a foam material, the stopper 402 can also be a foam member and be integrally molded with the first support member 401. In this way, the molding efficiency of the stopper 402 and the first support member 401 can be improved, and the steps of the production process can be reduced.

[0110] In addition, the limiting member 402 and the first support member 401 are constructed as an integrated structure, which can also avoid the need for additional connecting members or fixing members between the first support member 401 and the limiting member 402, further improving the production efficiency of the support assembly 40.

[0111] Thus, the air conditioner indoor unit 100 provided in the embodiment of the present application is provided with a support assembly 40, which extends along the length of the housing 10. The support assembly 40 includes a first support member 401 and a stop member 402. The first support member 401 can fully support the heat exchanger 20 along the length of the housing 10. In this way, when the heat exchanger 20 is subjected to external impact, the middle portion of the heat exchanger 20 will not be easily deformed due to lack of support. The stop member 402 can limit the heat exchanger 20 to prevent the heat exchanger 20 from moving toward the water tray 105 and falling from the first support member 401 under the action of a large impact force, thereby reducing the risk of deformation of the heat exchanger 20 and refrigerant leakage.

[0112] In some embodiments, the limiting member 402 is located on a side of the heat exchanger 20 away from the top plate 103 , and the limiting member 402 is used to limit the heat exchanger 20 from sliding along the supporting surface 4011 .

[0113] The stopper 402 can be disposed at the end of the support surface 4011 facing away from the top plate 103. Even if the heat exchanger 20 is subjected to a large impact force and undergoes a certain displacement, the stopper 402 can still limit the heat exchanger 20 to prevent the heat exchanger 20 from sliding along the support surface 4011 and separating from the support surface 4011 due to the excessive impact force.

[0114] Thus, the air conditioner indoor unit 100 provided in the embodiment of the present application is provided with a support assembly 40, which extends along the length of the housing 10. The support assembly 40 includes a first support member 401 and a stop member 402. The first support member 401 can fully support the heat exchanger 20 along the length of the housing 10. In this way, when the heat exchanger 20 is subjected to external impact, the central portion of the heat exchanger 20 will not be easily deformed due to lack of support. The stop member 402 is provided on the side of the support surface 4011 facing away from the top plate 103 to prevent the heat exchanger 20 from sliding relative to the support surface 4011 and detaching from the support surface 4011, causing the heat exchanger 20 to fall toward the bottom plate 104, thereby reducing the risk of refrigerant leakage and ensuring the working performance of the heat exchanger 20.

[0115] In some embodiments, the support surface 4011 of the first support member 401 is tilted and forms an angle with the top plate 103. It is understood that since the heat exchanger 20 is tilted between the top plate 103 and the bottom plate 104, the support surface 4011 used to support the top of the heat exchanger 20 is also tilted, which can better adapt to the planar structure of the top of the heat exchanger 20 and ensure that the heat exchanger 20 can be stably supported on the support surface 4011.

[0116] Specifically, the included angle between the supporting surface 4011 and the top plate 103 is an acute angle, so as to be adapted to the tilted heat exchanger 20 .

[0117] In some embodiments, as Figure 6 As shown, along the inclined direction of the support surface 4011 , the length L1 of the limiting member 402 satisfies: L1 > 8 mm, L1 < 20 mm.

[0118] L1>8mm can ensure the structural strength of the limiting member 402. Especially when the limiting member 402 is a foamed foam member, the limiting member 402 needs to have a certain length along the inclined direction of the support surface 4011 to have sufficient structural strength to effectively limit the heat exchanger 20.

[0119] If L1 is less than 8 mm, the insufficient length of the stopper 402 may make it unable to withstand the shock and vibration that the heat exchanger 20 may encounter during transportation or installation. Consequently, the stopper 402 may be deformed or damaged due to excessive force, thereby losing its ability to retain the heat exchanger 20. If the stopper 402 cannot effectively retain the heat exchanger 20, the heat exchanger 20 may deform during significant displacement, potentially affecting its performance and lifespan.

[0120] L1 is less than 20 mm, which can prevent the limiting member 402 from excessively blocking the heat exchanger 20, thereby reducing obstruction to the airflow in the air-conditioning indoor unit 100 and ensuring the heat exchange efficiency and air duct smoothness of the air conditioner.

[0121] If L1>20mm, the limiter 402 may interfere with other structural components in the housing 10 due to its excessive length, affecting the compactness of the design of the air-conditioning indoor unit 100, and may also block the heat exchanger 20, reducing the heat exchange efficiency of the heat exchanger 20.

[0122] Specifically, L1 can be 9mm, 11mm, 13mm, 15mm, 16mm or 20mm, so that the structural strength of the limiter 402 can be taken into account without causing the limiter 402 to occupy too much space in the air-conditioning indoor unit 100, so as to avoid interference between the limiter 402 and other components.

[0123] In some embodiments, the limiting member 402 and the supporting surface 4011 are connected by an arc transition.

[0124] When the heat exchanger 20 is subjected to impact or vibration during transportation or installation, the edge of the heat exchanger 20 may come into contact with the stopper 402, exerting a certain impact force on the stopper 402. If the stopper 402 and the support surface 4011 are connected at a right angle, the impact force exerted by the heat exchanger 20 on the stopper 402 may be concentrated at the right angle, increasing the risk of damage to the stopper 402. By using an arc transition to connect the stopper 402 and the support surface 4011, the impact force can be more smoothly distributed near the contact point between the stopper 402 and the support surface 4011, thereby reducing the possibility of damage to the stopper 402. This not only extends the service life of the support assembly 40, but also ensures the overall performance and stability of the air conditioner indoor unit 100.

[0125] In some embodiments, as Figure 7 and Figure 8 As shown, the first support member 401 further includes an isolation portion 4012. The isolation portion 4012 is formed at one end of the first support member 401 close to the top plate 103. The isolation portion 4012 is located between the top plate 103 and the heat exchanger 20.

[0126] Because the first support member 401 can be made of a foam material, it can have a certain degree of thermal insulation. The isolation portion 4012 is located between the top plate 103 and the heat exchanger 20, which can reduce the heat or cold transferred from the heat exchanger 20 to the top plate 103. Especially when the air conditioner indoor unit 100 is in cooling mode, reducing the cold transferred from the heat exchanger 20 to the top plate 103 can reduce or prevent the phenomenon of condensation caused by the low temperature of the top plate 103.

[0127] Specifically, if Figure 7 and Figure 8As shown, the isolation portion 4012 may protrude from the support surface 4011, and the heat exchanger 20 abuts against the isolation portion 4012. The isolation portion 4012 may be attached to the top plate 103, so that the isolation portion 4012 can achieve a heat insulation effect.

[0128] In some embodiments, as Figure 7 and Figure 8 As shown, along the inclination direction of the support surface 4011, the isolation portion 4012 and the limiting portion are respectively located at both ends of the support surface 4011. The isolation portion 4012 and the limiting portion are respectively located at both ends of the support surface 4011, so that the first support member 401 can not only limit and support the heat exchanger 20, but also achieve the function of thermally insulating the heat exchanger 20 from the top plate 103, thereby further streamlining the structural components of the air conditioner indoor unit 100.

[0129] In some embodiments, the first support member 401 may include an embedded part, which may be a metal part, for example, a sheet metal part.

[0130] The embedded parts have a certain structural strength and provide a stable supporting foundation for the entire first support member 401 .

[0131] In some embodiments, the embedded components can be secured to the top plate 103 by welding, riveting, or threading. The specific connection method selected depends on factors such as the material and thickness of the top plate 103, and the shape and size of the embedded components. Regardless of the connection method used, the embedded components can be securely secured to the top plate 103 to withstand the weight and vibration of the heat exchanger 20.

[0132] In some embodiments, the exterior of the embedded component may be covered with a foam layer.

[0133] On the one hand, the limit member 402 can be integrally processed and formed with the foam layer. The limit member 402 can be directly formed during the production process of the foam layer without being fixed to the foam layer through additional connectors or adhesives. This integrated structure not only simplifies the production process and reduces the production cost of the first support member 401, but also ensures a close connection between the limit member 402 and the foam layer, thereby improving the stability and durability of the entire first support member 401. On the other hand, the foam layer is coated on the embedded part and is tightly combined with the embedded part to form an integrated structure. The foam layer has excellent properties such as light weight, heat insulation, and sound insulation. It can also effectively absorb and disperse vibrations and impacts from the heat exchanger 20, protecting the heat exchanger 20 from damage. On the other hand, the presence of the foam layer can also reduce heat conduction and improve the energy efficiency ratio of the air-conditioning indoor unit 100.

[0134] In some embodiments, as Figure 6As shown, the air conditioning indoor unit 100 may further include a gasket 50 . The gasket 50 is disposed on the support surface 4011 and is located between the support surface 4011 and the heat exchanger 20 .

[0135] Specifically, the gasket 50 can be made of a material with excellent elasticity and wear resistance, such as rubber, silicone, or a special synthetic material. This effectively absorbs and disperses vibration and impact from the heat exchanger 20, further reducing the risk of damage to the fins and copper tubes of the heat exchanger 20. Furthermore, the gasket's wear resistance ensures that its shape and performance will not significantly change during long-term operation, thereby providing continuous support and protection for the heat exchanger 20.

[0136] It is understood that the provision of the gasket 50 can also adjust the gap between the heat exchanger 20 and the support surface 4011 to a certain extent, thereby optimizing the wind field distribution and noise level of the air conditioner indoor unit 100. By properly adjusting the thickness and shape of the gasket 50, the amount of air passing between the heat exchanger 20 and the support surface 4011 can be reduced, effectively reducing wind resistance and noise generation.

[0137] In some embodiments, the pad 50 is a closed cell sponge pad 50 .

[0138] It should be noted that the closed-cell structure of the closed-cell sponge gasket 50 provides excellent waterproofing. Compared to open-cell sponges, the pores in closed-cell sponges are independent of each other, making it less likely for them to form through-channels. Therefore, it effectively prevents water from penetrating and diffusing. Thus, the closed-cell sponge gasket 50 effectively prevents condensed water dripping from the heat exchanger 20 from reaching areas on the bottom plate 104 where the water tray 105 is not located, thus avoiding potential water leakage.

[0139] In some embodiments, as Figure 9 As shown, the air conditioning indoor unit 100 may further include a second support member 60. The second support member 60 is connected to the side plate 106 and the end portion of the heat exchanger 20 along the length direction.

[0140] During operation of the air conditioner indoor unit 100, the heat exchanger 20 may experience certain displacement or deformation due to air flow, temperature changes, vibration, etc. The second support member 60 is connected to the side plate 106 and the end portion of the heat exchanger 20 along the length direction, so that the side plate 106 can provide effective support for the end portion of the heat exchanger 20 along the length direction, so that the heat exchanger 20 can always maintain a predetermined position and posture.

[0141] In this way, the support assembly 40 can provide structural support for the portion of the heat exchanger 20 extending along the length direction of the shell 10, and the second support member 60 can also provide structural support for the end of the heat exchanger 20, so that the heat exchanger 20 as a whole is more stable and reliable during the operation of the air-conditioning indoor unit 100.

[0142] In some embodiments, the second support member 60 may be connected to the side plate 106 , and the second support member 60 may be fixed to the side plate 106 by welding, bolting, or other fastening methods.

[0143] Optionally, the second support member 60 may be a sheet metal member or other metal structural member.

[0144] In some embodiments, the second support member 60 is configured as a triangular structure.

[0145] Since the heat exchanger 20 is arranged obliquely between the top plate 103 and the bottom plate 104, the second support member 60 is constructed as a triangular structure, so that the hypotenuse of the triangle can be adapted to the inclination direction of the second support member 60, so that the second support member 60 can be connected to the heat exchanger 20.

[0146] In addition, the triangular structure has relatively stable geometric characteristics, so it can improve the load-bearing capacity and anti-deformation ability of the second support member 60, thereby further extending the service life of the heat exchanger 20 and the entire air-conditioning indoor unit 100.

[0147] In some embodiments, the side plate 106 may include a first side plate 106 a and a second side plate 106 b that are perpendicular to each other. The second support member 60 may be disposed at one end of the heat exchanger 20 and connected to the first side plate 106 a .

[0148] Furthermore, the space between the second support member 60 and the shell 10 can be used to accommodate pipelines of the heat exchanger 20 .

[0149] In some embodiments, as Figure 10 As shown, the air conditioning indoor unit 100 may further include a third support member 70. The third support member 70 is disposed on the second side plate 106b, and the third support member 70 and the second support member 60 are respectively disposed at both ends of the heat exchanger 20 along the length direction.

[0150] Specifically, the third support member 70 is configured as a bar-shaped connection structure to reserve installation space for other components inside the air conditioning indoor unit 100 .

[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
