Description

Technical Field

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

[0002] As one of the most expandable home appliances, air conditioners have more and more integrated functional modules. In addition to the original cooling and heating modules, they also have humidification modules for humidifying indoor air.

[0003] In related technologies, when water needs to be added to the liquid storage tank of the humidification module, part of the humidification module needs to protrude from the liquid storage installation cavity of the air conditioner in order to add water to the liquid storage tank. After the water is added, the humidification module needs to be put back into the liquid storage installation cavity. Repeating this operation many times can easily cause the humidification module to wear out and fail. Utility Model Content

[0004] This application discloses an indoor air conditioning unit that can solve the problem of humidification modules being easily worn and failing.

[0005] To achieve the above objectives, in a first aspect, this application discloses an indoor air conditioning unit, comprising:

[0006] The housing has an air conditioning installation cavity and a liquid storage installation cavity formed inside it. The housing is provided with an air inlet and an air outlet communicating with the air conditioning installation cavity. The housing is also provided with an installation port communicating with the liquid storage installation cavity.

[0007] Air conditioning module, the air conditioning module includes:

[0008] A fan is disposed in the air conditioner mounting cavity, and the fan is used to draw air from outside the housing into the air conditioner mounting cavity through the air inlet;

[0009] A heat exchanger is disposed in the air conditioner mounting cavity, and the heat exchanger is used to exchange heat with the air in the air conditioner mounting cavity. The fan is also used to blow the heat-exchanged air out of the air conditioner mounting cavity through the air outlet.

[0010] Humidification module, the humidification module comprising:

[0011] Liquid storage tank assembly;

[0012] A first rotating structure is disposed between the liquid storage tank assembly and the housing;

[0013] A second rotating structure is disposed between the liquid storage tank assembly and the housing;

[0014] The liquid storage tank assembly is rotatably mounted on the housing via the first rotating structure and the second rotating structure, so that the liquid storage tank assembly rotates around the first axis of the first rotating structure or the second axis of the second rotating structure, and rotates through the mounting port to enter and exit the liquid storage mounting cavity.

[0015] When the humidification module includes a first rotating structure and a second rotating structure, since the liquid storage tank assembly can rotate around the first axis of the first rotating structure or the second axis of the second rotating structure and enter and exit the liquid storage cavity through the mounting port, the rotating shaft of the liquid storage tank assembly can switch between the first axis of the first rotating structure and the second axis of the second rotating structure during the process of rotating the liquid storage tank assembly into and out of the liquid storage cavity through the mounting port.

[0016] In layman's terms, during the process of the liquid storage tank assembly rotating and entering and exiting the liquid storage installation cavity through the installation port, the force is borne by the first rotating structure for a period of time and by the second rotating structure for another period of time. In this way, the force borne by each rotating structure in the first and second rotating structures can be distributed to a certain extent, so that the force borne by each rotating structure is shorter. This reduces the possibility of friction and wear of the rotating structure during the repeated entry and exit of the liquid storage tank assembly into and out of the liquid storage installation cavity, and thus avoids the failure of the humidification module due to wear.

[0017] Optionally, when the liquid storage tank assembly rotates through the mounting port into and out of the liquid storage mounting cavity, the liquid storage tank assembly can switch from rotating about the first axis of the first rotating structure to rotating about the second axis of the second rotating structure.

[0018] As the liquid storage tank assembly rotates through the mounting port into and out of the liquid storage cavity, it can switch from rotating around the first axis of the first rotating structure to rotating around the second axis of the second rotating structure. Therefore, the force on each rotating structure in the first and second rotating structures can be distributed, resulting in a shorter stress time for each rotating structure. This reduces the possibility of friction and wear on the rotating structures during the repeated entry and exit of the liquid storage tank assembly into and out of the liquid storage cavity, thereby preventing the humidification module from wearing out and failing.

[0019] Optionally, both the first rotating structure and the second rotating structure are disposed near the bottom of the liquid storage tank assembly, and / or the first rotating structure and the second rotating structure are arranged sequentially in the liquid storage mounting cavity along a direction perpendicular to the mounting opening.

[0020] By positioning both the first and second rotating structures close to the bottom of the liquid storage tank assembly, the rotation radius of the bottom of the liquid storage tank assembly will not be too large when the liquid storage tank assembly rotates around the first axis of the first rotating structure or the second axis of the second rotating structure. Therefore, the liquid storage installation cavity does not need to reserve a large space for the bottom of the liquid storage tank assembly to rotate, allowing the size of the liquid storage installation cavity to be designed to be more compact.

[0021] Optionally, the first rotating structure is disposed close to the mounting port, and the second rotating structure is disposed away from the mounting port.

[0022] By positioning the first rotating structure close to the mounting port and the second rotating structure away from the mounting port, the rotating shaft of the liquid storage tank assembly can switch regularly between the first and second rotating structures during the process of the liquid storage tank assembly entering and exiting the liquid storage mounting cavity, thereby better preventing the humidification module from wearing out and failing.

[0023] Optionally, the first rotating structure includes:

[0024] A first rotating shaft is disposed on one of the housing and the liquid storage tank assembly;

[0025] A first insertion hole is provided on the other of the housing and the liquid storage tank assembly. A first rotating shaft is inserted into the first insertion hole. The first insertion hole is used to allow the first rotating shaft to swing within the first insertion hole when the liquid storage tank assembly rotates about the second axis of the second rotating structure.

[0026] When the reservoir assembly switches to rotating around the second axis of the second rotating structure, the first rotating shaft will swing along with the reservoir assembly. The first insertion hole provides space for the first rotating shaft to swing with the reservoir assembly. In simpler terms, when the reservoir assembly rotates around the second axis of the second rotating structure, the first insertion hole does not tightly fix the first rotating shaft within itself, thus ensuring that the reservoir assembly can rotate around the second axis of the second rotating structure. Specifically, the first insertion hole can be a first strip-shaped hole.

[0027] Optionally, the first rotating shaft includes:

[0028] A first shaft portion is disposed on one of the housing and the liquid storage tank assembly;

[0029] The first reinforcing rib plate is provided in multiple ways. The multiple first reinforcing rib plates are arranged in a circumferentially spaced array on the peripheral wall of the first shaft portion. Each first reinforcing rib plate extends axially along the first shaft portion. The multiple first reinforcing rib plates are inserted into the first insertion hole.

[0030] Because multiple first reinforcing ribs are arranged in a circumferentially spaced array on the peripheral wall of the first shaft body, and each first reinforcing rib extends axially along the first shaft body, the first reinforcing ribs, on the one hand, ensure the overall mechanical strength of the first rotating shaft while also reducing the amount of material used, thus achieving the goals of increasing the mechanical strength of the first rotating shaft and reducing material consumption. On the other hand, they also reduce the contact area between the first rotating shaft and the wall of the first insertion hole, thereby reducing the friction between the first rotating shaft and the wall of the first insertion hole to a certain extent, making the first rotating shaft rotate or slide more smoothly within the first insertion hole.

[0031] Optionally, one of the housing and the liquid storage tank assembly is provided with a plurality of second reinforcing ribs, the plurality of second reinforcing ribs corresponding one-to-one with a plurality of first reinforcing ribs, and each second reinforcing rib being connected to the corresponding first reinforcing rib.

[0032] Since the second reinforcing rib is set on the liquid storage tank assembly, and multiple second reinforcing ribs correspond one-to-one with multiple first reinforcing ribs, and each second reinforcing rib is connected to the corresponding first reinforcing rib, the first reinforcing rib can be set on the liquid storage tank assembly very securely under the action of the second reinforcing rib, thereby enabling the entire first rotating shaft to be set on the liquid storage tank assembly very securely.

[0033] Optionally, the second rotating structure includes:

[0034] A second rotating shaft is disposed on one of the housing and the liquid storage tank assembly;

[0035] A second insertion hole is provided on the other of the housing and the liquid storage tank assembly. A second rotating shaft is inserted into the second insertion hole. The second insertion hole is used to allow the second rotating shaft to swing within the second insertion hole when the liquid storage tank assembly rotates about the first axis of the first rotating structure.

[0036] When the reservoir assembly switches to rotating around the first axis of the first rotating structure, the second rotating shaft will swing along with the reservoir assembly. The second insertion hole provides space for the second rotating shaft to swing with the reservoir assembly. In simpler terms, when the reservoir assembly rotates around the first axis of the first rotating structure, the second insertion hole does not tightly fix the second rotating shaft within itself, thus ensuring that the reservoir assembly can rotate around the first axis of the first rotating structure. Specifically, the second insertion hole can be a second strip-shaped hole.

[0037] Optionally, the length of the second insertion hole along the second rotation axis in the swing direction within the second insertion hole is a first length, and the length of the first insertion hole along the first rotation axis in the swing direction within the first insertion hole is a second length, wherein the first length is greater than the second length.

[0038] By making the length of the second strip hole (second insertion hole) greater than the length of the first strip hole (first insertion hole), the lengths of the second strip hole and the first strip hole can be arranged more reasonably while ensuring that the liquid storage tank assembly can rotate through the mounting port to enter and exit the liquid storage installation cavity. This avoids the situation where the liquid storage tank assembly cannot rotate due to an unreasonable length arrangement of the two strip holes.

[0039] Optionally, a limiting structure is provided between the housing and the liquid storage tank assembly, the limiting structure being used to restrict the rotation of the liquid storage tank assembly about the first axis of the first rotating structure or the second axis of the second rotating structure within a preset angle.

[0040] By setting a limiting structure, the rotation of the liquid storage tank assembly around the first axis of the first rotating structure or the second axis of the second rotating structure can be kept within a preset angle. In this way, the situation where the liquid storage tank assembly falls out of the liquid storage installation cavity due to excessive rotation angle can be avoided.

[0041] Optionally, the limiting structure includes:

[0042] A limiting hole is provided on one of the housing and the liquid storage tank assembly;

[0043] A limiting member is disposed on the other of the housing and the liquid storage tank assembly. When the liquid storage tank assembly rotates about the first axis of the first rotating structure or the second axis of the second rotating structure, the limiting member slides within the limiting hole.

[0044] When the limiting structure includes a limiting component and a limiting hole, the rotation of the liquid storage tank assembly can be limited within a preset angle through the cooperation of the limiting component and the limiting hole. The implementation method is simple and can reduce the cost of the limiting structure to a certain extent.

[0045] Optionally, the limiting member is higher than the first axis of the first rotating structure and higher than the second axis of the second rotating structure in the vertical direction.

[0046] By making the limiting member higher than the first axis of the first rotating structure and higher than the second axis of the second rotating structure in the vertical direction, the limiting member can be offset from the first axis of the first rotating structure and the second axis of the second rotating structure in the vertical direction. In this way, the distance between the limiting member and the first axis of the first rotating structure and the second axis of the second rotating structure in the vertical direction can be greater, thereby better guiding the rotation of the liquid storage tank assembly, making the rotation of the liquid storage tank assembly smoother and more stable.

[0047] Optionally, the liquid storage tank assembly includes:

[0048] The tank cover and the liquid storage tank assembly are rotatably mounted on the housing via the first rotating structure and the second rotating structure. The tank cover has a placement cavity inside and a loading / unloading port communicating with the placement cavity on the tank cover.

[0049] A liquid storage tank is disposed within the placement cavity, and the access port allows the liquid storage tank to enter and exit the placement cavity.

[0050] When the tank cover has a placement cavity and a loading / unloading port communicating with the placement cavity is provided on the tank cover, it is very convenient to add water to the storage tank, that is, it makes the process of adding water to the storage tank very convenient.

[0051] Optionally, the indoor unit of the air conditioner further includes:

[0052] A locking device is disposed on the housing. The locking device is used to lock the liquid storage tank assembly in the liquid storage mounting cavity when the liquid storage tank assembly is pressed by the locking device. The locking device is also used to unlock the liquid storage tank assembly when the liquid storage tank assembly is pressed again by the locking device.

[0053] When the indoor unit of the air conditioner also includes a locking device, the purpose of locking or unlocking the liquid tank assembly can be achieved by pressing the locking device, which is very simple to operate. Therefore, the complexity of locking and unlocking the liquid tank assembly can be simplified.

[0054] Optionally, the housing includes:

[0055] front;

[0056] The back side is positioned opposite to the front side;

[0057] The side is connected between the front and the back, and the mounting port is provided on the side and / or the front.

[0058] By placing the mounting port on the side, compared to placing it on the front, two advantages are made: First, when rotating the liquid receiver assembly out of the liquid receiver installation cavity through the mounting port, there is no need to remove the decorative panel beforehand, making it very convenient and quick. Second, it also reduces the impact of the mounting port on the appearance of the air conditioner indoor unit, thereby improving the unit's aesthetic appeal.

[0059] When the installation port is located on the front, when the liquid storage tank assembly is rotated out of the liquid storage installation cavity through the installation port, there is no need to consider reserving space on the side during the installation of the indoor air conditioner unit. This can minimize the possibility of interference between the liquid storage tank assembly and the surrounding environment, making the choice of installation location for the indoor air conditioner unit more flexible and adaptable.

[0060] Compared with related technologies, this application has at least the following beneficial effects:

[0061] In this application, since the liquid storage tank assembly can rotate around the first axis of the first rotating structure or the second axis of the second rotating structure and enter and exit the liquid storage cavity through the mounting port, the rotating shaft of the liquid storage tank assembly can switch between the first axis of the first rotating structure and the second axis of the second rotating structure during the process of rotating the liquid storage tank assembly into and out of the liquid storage cavity through the mounting port. In this way, the force on each rotating structure in the first rotating structure and the second rotating structure can be distributed to a certain extent, so that the force on each rotating structure is shorter, thereby reducing the possibility of friction and wear of the rotating structure during the repeated entry and exit of the liquid storage tank assembly into and out of the liquid storage cavity, and thus avoiding the wear and failure of the humidification module.

[0086] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0087] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0088] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0089] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.

Unless otherwise stated, "a plurality of" means two or more.

[0091] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0092] As one of the most expandable home appliances, air conditioners have more and more integrated functional modules. In addition to the original cooling and heating modules, they also have humidification modules for humidifying indoor air.

[0093] In related technologies, when water needs to be added to the liquid storage tank of the humidifier module, a portion of the humidifier module needs to protrude from the liquid storage cavity of the air conditioner to allow water to be added. After adding water, the humidifier module needs to be retracted into the liquid storage cavity. Repeating this process multiple times can easily lead to wear and tear on the humidifier module, causing it to fail. Therefore, this application provides an air conditioner indoor unit to solve the above problems.

[0094] The technical solution of this application will be described below with reference to the accompanying drawings and embodiments.

[0095] Figure 1 This is a structural schematic diagram of an air conditioner indoor unit 100 provided in one embodiment of this application. See also: Figure 1 The indoor unit of the air conditioner 100 includes a housing 1, and an air conditioner installation cavity 11 is formed inside the housing 1.

[0096] The material of the aforementioned housing 1 can be plastic or metal, etc., and this embodiment does not limit it.

[0097] The shape of housing 1 can be as follows: Figure 1 The shape of the housing 1 shown is a cuboid. Of course, the shape of the housing 1 can also be a cylinder or any other possible shape. This embodiment does not limit the shape of the housing 1.

[0098] The aforementioned air conditioner mounting cavity 11 refers to the space within the casing 1 used for installing the fan and heat exchanger, etc. When an air conditioner mounting cavity 11 is formed within the casing 1, it provides a dedicated space for installing the fan and heat exchanger, making the environment in which the fan and heat exchanger are located safer. On the other hand, it also provides structural support for subsequent heating or cooling via the fan and heat exchanger, enabling the indoor unit 100 of the air conditioner to have heating and cooling functions.

[0099] In some embodiments, see Figure 1 and Figure 2 , Figure 2 yes Figure 1 The diagram shows the structure of the indoor unit 100 of the air conditioner from the positive X-axis perspective. The housing 1 is provided with an air inlet 13 and an air outlet 14 that connect to the air conditioner mounting cavity 11.

[0100] The air inlet 13 and air outlet 14 can be rectangular or any other possible shape, and this embodiment does not limit them.

[0101] Furthermore, the aforementioned air inlet 13 and air outlet 14 can be located at any position on the housing 1. For example, in one possible implementation, see [link to relevant documentation]. Figure 1 and Figure 2 The air outlet 14 can be located on the front of the housing 1 and the air inlet 13 can be located on the back of the housing 1. Of course, in other embodiments, the air outlet 14 can be located on the back of the housing 1 and the air inlet 13 can be located on the front of the housing 1. This embodiment does not limit this.

[0102] It should be noted that the front of the casing 1 mentioned above refers to the side of the casing 1 facing the user after the indoor unit 100 of the air conditioner is installed, and the back of the casing 1 refers to the side of the casing 1 away from the user.

[0103] In some embodiments, see Figure 1 and Figure 2 The indoor unit 100 of the air conditioner also includes an air conditioning module 2, which includes a fan (not shown in the figure). The fan is located in the air conditioning mounting cavity 11 and is used to draw air from outside the casing 1 into the air conditioning mounting cavity 11 through the air inlet 13.

[0104] The aforementioned fan can be a cross-flow fan or any possible fan, and this embodiment does not limit it.

[0105] Since the fan is located in the air conditioning installation cavity 11, when the fan is running, it can draw air from outside the casing 1 into the air conditioning installation cavity 11 through the air inlet 13. This prepares the air for subsequent heat exchange in the air conditioning installation cavity 11.

[0106] In some embodiments, see Figure 1 The air conditioning module 2 also includes a heat exchanger (not shown in the figure), which is located in the air conditioning installation cavity 11. The heat exchanger is used to exchange heat with the air in the air conditioning installation cavity 11. The fan is also used to blow the heat-exchanged air out of the air conditioning installation cavity 11 through the air outlet 14.

[0107] Since the heat exchanger is located in the air conditioning installation cavity 11, when the fan draws air from outside the casing 1 into the air conditioning installation cavity 11 through the air inlet 13, the heat exchanger located in the air conditioning installation cavity 11 can exchange heat with the air. Then, the fan can blow the heat-exchanged air out of the air conditioning installation cavity 11 through the air outlet 14.

[0108] When the air after heat exchange is blown out of the air conditioner installation cavity 11 through the air outlet 14, the air will enter the room, thereby achieving the purpose of heating or cooling the room, so that the indoor unit 100 of the air conditioner has heating and cooling functions.

[0109] In some embodiments, see Figure 1 and Figure 3 , Figure 3 yes Figure 1 An exploded view of an indoor unit 100 of an air conditioner shows that a liquid storage cavity 12 is formed inside the casing 1, and an installation port 15 communicating with the liquid storage cavity 12 is provided on the casing 1.

[0110] Since the mounting port 15 connects to the liquid storage mounting cavity 12, the liquid storage tank assembly 31 can be easily installed in the liquid storage mounting cavity 12 through the mounting port 15.

[0111] To avoid interference between the liquid storage cavity 12 and the air conditioning cavity 11, in some embodiments, see [reference needed]. Figure 3 The liquid storage cavity 12 and the air conditioning cavity 11 can be arranged sequentially from bottom to top, which can avoid interference between the liquid storage cavity 12 and the air conditioning cavity 11.

[0112] In some embodiments, see Figure 1 and Figure 3 The indoor unit 100 of the air conditioner also includes a humidification module 3.

[0113] When the air conditioner indoor unit 100 also includes a humidification module 3, in addition to the conventional functions of an air conditioner, such as cooling and heating, the air conditioner indoor unit 100 can also humidify the indoor air through the humidification module 3. That is, the air conditioner indoor unit 100 also has a humidification function, thus making the functions of the air conditioner indoor unit 100 more diverse.

[0114] In some embodiments, see Figure 3 , Figure 4 At once Figure 5, Figure 4 yes Figure 3 A schematic diagram of the structure of the intermediate liquid storage tank assembly 31. Figure 5 yes Figure 3 The diagram shows the structure of the indoor unit 100 of the air conditioner from a positive X-axis perspective (part of the casing 1 is omitted). The humidification module 3 includes a liquid storage tank assembly 31, a first rotating structure 32, and a second rotating structure 33. See [link / reference]. Figure 6 and Figure 7 , Figure 6 yes Figure 5 A schematic diagram of the disassembled structure of the indoor unit 100 of the air conditioner. Figure 7 yes Figure 6 The image shows a partial enlarged view of the indoor unit 100 of the air conditioner at position A, wherein the first rotating structure 32 is disposed between the liquid storage tank assembly 31 and the housing 1, and the second rotating structure 33 is disposed between the liquid storage tank assembly 31 and the housing 1.

[0115] See Figure 4 , Figure 6 and Figure 8 , Figure 8 yes Figure 1 The diagram shows the structure of the indoor unit 100 of the air conditioner after the liquid storage tank assembly 31 rotates out of the liquid storage installation cavity 12 through the mounting port 15. The liquid storage tank assembly 31 is rotatably mounted on the housing 1 through the first rotating structure 32 and the second rotating structure 33, so that the liquid storage tank assembly 31 rotates around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, so as to rotatably enter and exit the liquid storage installation cavity 12 through the mounting port 15.

[0116] Since the liquid storage tank assembly 31 is rotatably mounted on the housing 1 via the first rotating structure 32 and the second rotating structure 33, and the liquid storage tank assembly 31 can rotate around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, and can enter and exit the liquid storage installation cavity 12 through the installation port 15 during rotation.

[0117] Therefore, when it is necessary to add water to the liquid storage tank 312 in the liquid storage tank assembly 31, it is only necessary to rotate the liquid storage tank assembly 31 around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, so that the liquid storage tank assembly 31 rotates out of the liquid storage installation cavity 12 from the installation port 15. Figure 8 When the liquid is in the middle state, water can be easily added to the storage tank 312.

[0118] After the liquid storage tank 312 is filled with water, the liquid storage tank assembly 31 is rotated again around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, so that the liquid storage tank assembly 31 is rotated from the mounting port 15 into the liquid storage mounting cavity 12. Figure 1When the humidification module 3 includes a first rotating structure 32 and a second rotating structure 33, the liquid storage tank assembly 31 can rotate around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33 and enter and exit the liquid storage installation cavity 12 through the mounting port 15. Therefore, during the process of the liquid storage tank assembly 31 rotating through the mounting port 15 to enter and exit the liquid storage installation cavity 12, the rotating shaft of the liquid storage tank assembly 31 can switch between the first axis O1 of the first rotating structure 32 and the second axis O2 of the second rotating structure 33.

[0119] In layman's terms, during the process of the liquid storage tank assembly 31 rotating through the mounting port 15 to enter and exit the liquid storage mounting cavity 12, the force is borne by the first rotating structure 32 for a period of time and by the second rotating structure 33 for another period of time. In this way, the force borne by each rotating structure in the first rotating structure 32 and the second rotating structure 33 can be distributed to a certain extent, so that the force borne by each rotating structure is shorter. This can reduce the possibility of friction and wear of the rotating structure during the repeated entry and exit of the liquid storage tank assembly 31 into and out of the liquid storage mounting cavity 12, and thus avoid the wear and failure of the humidification module 3.

[0120] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The indoor unit 100 of the air conditioner includes a housing 1, an air conditioning module 2 and a humidification module 3. The housing 1 has an air conditioning installation cavity 11 and a liquid storage installation cavity 12. The housing 1 is provided with an air inlet 13 and an air outlet 14 communicating with the air conditioning installation cavity 11. The housing 1 is also provided with an installation port 15 communicating with the liquid storage installation cavity 12.

[0121] The air conditioning module 2 includes a fan and a heat exchanger. The fan is located in the air conditioning mounting cavity 11 and is used to draw air from outside the housing 1 into the air conditioning mounting cavity 11 through the air inlet 13. The heat exchanger is located in the air conditioning mounting cavity 11 and is used to exchange heat with the air inside the air conditioning mounting cavity 11. The fan is also used to blow the heat-exchanged air out of the air conditioning mounting cavity 11 through the air outlet 14.

[0122] See Figure 4 , Figure 6 and Figure 8The humidification module 3 includes a liquid storage tank assembly 31, a first rotating structure 32, and a second rotating structure 33. The first rotating structure 32 is disposed between the liquid storage tank assembly 31 and the housing 1, and the second rotating structure 33 is disposed between the liquid storage tank assembly 31 and the housing 1. The liquid storage tank assembly 31 is rotatably disposed on the housing 1 via the first rotating structure 32 and the second rotating structure 33, so that the liquid storage tank assembly 31 rotates around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, and rotatably enters and exits the liquid storage mounting cavity 12 through the mounting port 15. In this embodiment, since the liquid storage tank assembly 31 can rotate around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33 and enter and exit the liquid storage installation cavity 12 through the mounting port 15, the rotation axis of the liquid storage tank assembly 31 can switch between the first axis O1 of the first rotating structure 32 and the second axis O2 of the second rotating structure 33 during the process of rotating the liquid storage tank assembly 31 into and out of the liquid storage installation cavity 12 through the mounting port 15. In this way, the force on each rotating structure in the first rotating structure 32 and the second rotating structure 33 can be distributed to a certain extent, so that the force on each rotating structure is shorter, thereby reducing the possibility of friction and wear of the rotating structure during the repeated entry and exit of the liquid storage tank assembly 31 into and out of the liquid storage installation cavity 12, and thus avoiding the wear and failure of the humidification module 3.

[0123] In some embodiments, see Figure 4 , Figure 6 and Figure 8 The liquid storage tank assembly 31 is rotatably mounted on the housing 1 via a first rotating structure 32 and a second rotating structure 33, allowing the liquid storage tank assembly 31 to rotatably enter and exit the liquid storage mounting cavity 12 through the mounting port 15. Specifically, when the liquid storage tank assembly 31 rotatably enters and exits the liquid storage mounting cavity 12 through the mounting port 15, the liquid storage tank assembly 31 can switch from rotating around the first axis O1 of the first rotating structure 32 to rotating around the second axis O2 of the second rotating structure 33.

[0124] In this embodiment, when the liquid storage tank assembly 31 rotates through the mounting port 15 to enter and exit the liquid storage mounting cavity 12, the liquid storage tank assembly 31 can switch from rotating around the first axis O1 of the first rotating structure 32 to rotating around the second axis O2 of the second rotating structure 33. Therefore, the force on each rotating structure in the first rotating structure 32 and the second rotating structure 33 can be dispersed, so that the force on each rotating structure is shorter. This reduces the possibility of friction and wear of the rotating structure during the process of the liquid storage tank assembly 31 entering and exiting the liquid storage mounting cavity 12 multiple times, and thus avoids the wear and failure of the humidification module 3.

[0125] In some embodiments, see Figure 4 Both the first rotating structure 32 and the second rotating structure 33 are located near the bottom of the liquid storage tank assembly 31.

[0126] By arranging both the first rotating structure 32 and the second rotating structure 33 close to the bottom of the liquid storage tank assembly 31, the rotation radius of the bottom of the liquid storage tank assembly 31 will not be too large when it rotates around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33. Therefore, the liquid storage mounting cavity 12 does not need to reserve too much space for the bottom of the liquid storage tank assembly 31 to rotate, making the size of the liquid storage mounting cavity 12 more compact.

[0127] Of course, the fact that the first rotating structure 32 and the second rotating structure 33 are both located near the bottom of the liquid storage tank assembly 31 is only one possible arrangement given in this embodiment. In other embodiments, the first rotating structure 32 and the second rotating structure 33 may also be located near the middle of the liquid storage tank assembly 31 along the height direction. This embodiment does not limit this.

[0128] In some embodiments, see Figure 3 The first rotating structure 32 and the second rotating structure 33 are arranged sequentially in the liquid storage installation cavity 12 along a direction perpendicular to the installation port 15.

[0129] By arranging the first rotating structure 32 and the second rotating structure 33 sequentially in the liquid storage mounting cavity 12 along a direction perpendicular to the mounting port 15, on the one hand, the first rotating structure 32 and the second rotating structure 33 can be hidden in the liquid storage mounting cavity 12, making the air conditioner indoor unit 100 look cleaner and thus improving the appearance of the air conditioner indoor unit 100. On the other hand, this arrangement also facilitates the switching of the rotating shaft of the liquid storage tank assembly 31 between the first rotating structure 32 and the second rotating structure 33 when the liquid storage tank assembly 31 rotates in and out of the mounting port 15, providing structural protection for the switching of the rotating shaft of the liquid storage tank assembly 31 between the first rotating structure 32 and the second rotating structure 33.

[0130] In some embodiments, see Figure 3 and Figure 8 The first rotating structure 32 is positioned close to the mounting port 15, and the second rotating structure 33 is positioned away from the mounting port 15.

[0131] By positioning the first rotating structure 32 close to the mounting port 15 and the second rotating structure 33 away from the mounting port 15, it is possible to ensure that when the liquid storage tank assembly 31 rotates out of the liquid storage mounting cavity 12 from the mounting port 15... Figure 8 In the intermediate state, the liquid storage tank assembly 31 can rotate around the first axis O1 of the first rotating structure 32, and at this time the gravity of the liquid storage tank assembly 31 mainly acts on the first rotating structure 32.

[0132] When it is necessary to transfer the liquid storage tank assembly 31 from the mounting port 15 into the liquid storage mounting cavity 12 ( Figure 1 In the middle state, initially, the liquid storage tank assembly 31 also rotates around the first axis O1 of the first rotating structure 32. As the liquid storage tank assembly 31 continues to gradually rotate from the mounting port 15 into the liquid storage mounting cavity 12, the liquid storage tank assembly 31 will switch to rotating around the second axis O2 of the second rotating structure 33 until the liquid storage tank assembly 31 rotates from the mounting port 15 into the liquid storage mounting cavity 12. Figure 1 (Mid-state).

[0133] When it is necessary to rotate the liquid storage tank assembly 31 from the mounting port 15 out of the liquid storage mounting cavity 12 ( Figure 8 In the middle state, initially, the liquid storage tank assembly 31 will rotate around the second axis O2 of the second rotating structure 33. As the liquid storage tank assembly 31 continues to gradually rotate out of the liquid storage installation cavity 12 from the mounting port 15, the liquid storage tank assembly 31 will switch to rotating around the first axis O1 of the first rotating structure 32 until the liquid storage tank assembly 31 rotates out of the liquid storage installation cavity 12 from the mounting port 15. Figure 8 (Mid-state).

[0134] As can be seen, by setting the first rotating structure 32 close to the mounting port 15 and the second rotating structure 33 away from the mounting port 15, the rotating shaft of the liquid storage tank assembly 31 can switch regularly between the first rotating structure 32 and the second rotating structure 33 during the process of the liquid storage tank assembly 31 entering and exiting the liquid storage mounting cavity 12, thereby better avoiding the wear and failure of the humidification module 3.

[0135] There are multiple ways to implement the first rotating structure 32 described above. In one possible implementation, see [link to relevant documentation]. Figure 4 , Figure 5 and Figure 9 , Figure 9 yes Figure 5 A partial enlarged view at position B shows that the first rotating structure 32 includes a first rotating shaft 321, which is disposed on one of the housing 1 and the liquid storage tank assembly 31.

[0136] Specifically, see Figure 4 In some embodiments, the first rotating shaft 321 may be disposed on the liquid storage tank assembly 31. Of course, in other embodiments, the first rotating shaft 321 may also be disposed on the housing 1. This embodiment does not limit this.

[0137] In some embodiments, see Figure 4 , Figure 5 and Figure 9The first rotating structure 32 also includes a first insertion hole 322, which is disposed on the other of the housing 1 and the liquid storage tank assembly 31. The first insertion hole 322 is a first strip-shaped hole. The first rotating shaft 321 is inserted into the first insertion hole 322. The first insertion hole 322 is used to allow the first rotating shaft 321 to swing within the first insertion hole 322 when the liquid storage tank assembly 31 rotates around the second axis O2 of the second rotating structure 33.

[0138] Since the first insertion hole 322 is a first strip-shaped hole, and the first rotating shaft 321 is inserted into the first insertion hole 322, when the liquid storage tank assembly 31 switches to rotating around the second axis O2 of the second rotating structure 33, the first rotating shaft 321 will swing along with the liquid storage tank assembly 31. The first insertion hole 322 can provide space for the first rotating shaft 321 to swing along with the liquid storage tank assembly 31. In simpler terms, when the liquid storage tank assembly 31 rotates around the second axis O2 of the second rotating structure 33, the first insertion hole 322 does not tightly fix the first rotating shaft 321 inside the first insertion hole 322, thereby ensuring that the liquid storage tank assembly 31 can rotate around the second axis O2 of the second rotating structure 33.

[0139] In order to make the first rotating shaft 321 swing more smoothly in the first insertion hole 322, in some embodiments, the extension trajectory of the first strip hole can be the same as the swing trajectory of the first rotating shaft 321. In this way, under the cooperation of the first insertion hole 322 and the first rotating shaft 321, the first insertion hole 322 can also guide the swing of the first rotating shaft 321, so that the liquid storage tank assembly 31 runs more smoothly when rotating around the second axis O2 of the second rotating structure 33.

[0140] In some embodiments, see Figure 4 and Figure 10 , Figure 10 for Figure 4 A partial enlarged view at position C shows that the first rotating shaft 321 includes a first shaft body 3211, which is disposed on one of the liquid storage tank assembly 31 and the housing 1.

[0141] Specifically, the first shaft portion 3211 can be disposed on the liquid storage tank assembly 31. Of course, in other embodiments, the first shaft portion 3211 can also be disposed on the housing 1. This embodiment does not limit this.

[0142] In some embodiments, see Figure 10The first rotating shaft 321 also includes a first reinforcing rib plate 3212. Multiple first reinforcing rib plates 3212 are provided. Multiple first reinforcing rib plates 3212 are arranged in a circumferentially spaced array on the peripheral wall of the first shaft body portion 3211. Each first reinforcing rib plate 3212 extends along the axial direction of the first shaft body portion 3211. Multiple first reinforcing rib plates 3212 are inserted into the first insertion hole 322.

[0143] Since multiple first reinforcing ribs 3212 are arranged in a circumferentially spaced array on the peripheral wall of the first shaft portion 3211, and each first reinforcing rib 3212 extends axially along the first shaft portion 3211, the first reinforcing ribs 3212, on the one hand, can ensure the overall mechanical strength of the first rotating shaft 321 is high while also ensuring that the material used in the first rotating shaft 321 is less, thus achieving the purpose of increasing the mechanical strength of the first rotating shaft 321 and reducing the material used in the first rotating shaft 321. On the other hand, it can also reduce the contact area between the first rotating shaft 321 and the wall of the first insertion hole 322, thereby reducing the friction between the first rotating shaft 321 and the wall of the first insertion hole 322 to a certain extent, making the first rotating shaft 321 rotate or slide more smoothly in the first insertion hole 322.

[0144] In some embodiments, see Figure 10 The liquid storage tank assembly 31 is provided with a plurality of second reinforcing ribs 3213, which correspond one-to-one with a plurality of first reinforcing ribs 3212, and each second reinforcing rib 3213 is connected to the corresponding first reinforcing rib 3212.

[0145] Since the second reinforcing rib 3213 is disposed on the liquid storage tank assembly 31, and the multiple second reinforcing ribs 3213 correspond one-to-one with the multiple first reinforcing ribs 3212, and each second reinforcing rib 3213 is connected to the corresponding first reinforcing rib 3212, under the action of the second reinforcing rib 3213, the first reinforcing rib 3212 can be very securely disposed on the liquid storage tank assembly 31, thereby making the entire first rotating shaft 321 very securely disposed on the liquid storage tank assembly 31.

[0146] In some embodiments, see Figure 4 The second rotating structure 33 includes a second rotating shaft 331, which is disposed on one of the housing 1 and the liquid storage tank assembly 31.

[0147] Specifically, the second rotating shaft 331 can be disposed on the liquid storage tank assembly 31. Of course, in other embodiments, the second rotating shaft 331 can also be disposed on the housing 1. This embodiment does not limit this.

[0148] In some embodiments, see Figure 4 , Figure 5 and Figure 9 The second rotating structure 33 also includes a second insertion hole 332, which is disposed on the other of the housing 1 and the liquid storage tank assembly 31. The second insertion hole 332 can be a second strip hole. The second rotating shaft 331 is inserted into the second insertion hole 332. The second insertion hole 332 is used to allow the second rotating shaft 331 to swing within the second insertion hole 332 when the liquid storage tank assembly 31 rotates around the first axis O1 of the first rotating structure 32.

[0149] Since the second insertion hole 332 is a second strip-shaped hole, and the second rotating shaft 331 is inserted into the second insertion hole 332, when the liquid storage tank assembly 31 switches to rotate around the first axis O1 of the first rotating structure 32, the second rotating shaft 331 will swing along with the liquid storage tank assembly 31. The second insertion hole 332 can provide space for the second rotating shaft 331 to swing along with the liquid storage tank assembly 31. In simpler terms, when the liquid storage tank assembly 31 rotates around the first axis O1 of the first rotating structure 32, the second insertion hole 332 does not tightly fix the second rotating shaft 331 inside the second insertion hole 332, thereby ensuring that the liquid storage tank assembly 31 can rotate around the first axis O1 of the first rotating structure 32.

[0150] In order to make the second rotating shaft 331 swing more smoothly in the second insertion hole 332, in some embodiments, the extension trajectory of the second strip hole can be the same as the swing trajectory of the second rotating shaft 331. In this way, under the cooperation of the second insertion hole 332 and the second rotating shaft 331, the swing of the second rotating shaft 331 by the second insertion hole 332 can also play a guiding role, so that the liquid storage tank assembly 31 runs more smoothly when rotating around the first axis O1 of the first rotating structure 32.

[0151] The structure of the second rotating shaft 331 can be the same as or similar to the structure of the first rotating shaft 321. Specifically, see [link to relevant documentation]. Figure 9 and Figure 10 The second rotating shaft 331 may include a second shaft body portion 3311 and a third reinforcing rib plate 3312. Multiple third reinforcing rib plates 3312 are provided. Multiple third reinforcing rib plates 3312 are arranged in a circumferentially spaced array on the peripheral wall of the second shaft body portion 3311. Each third reinforcing rib plate 3312 extends axially along the second shaft body portion 3311. Multiple third reinforcing rib plates 3312 are inserted into the second insertion hole 332.

[0152] The structure of the second shaft portion 3311 can be the same as that of the first shaft portion 3211, and it can bring the same or similar beneficial effects as the first shaft portion 3211. For details, please refer to the description of the first shaft portion 3211 in the above embodiments, which will not be repeated here. Similarly, the structure of the third reinforcing rib plate 3312 can be the same as that of the first reinforcing rib plate 3212, and it can bring the same or similar beneficial effects as the first reinforcing rib plate 3212. For details, please refer to the description of the first reinforcing rib plate 3212 in the above embodiments, which will not be repeated here.

[0153] In some embodiments, see Figure 9 The length of the second insertion hole 332 along the second rotation axis 331 in the swing direction within the second insertion hole 332 is the first length, and the length of the first insertion hole 322 along the first rotation axis 321 in the swing direction within the first insertion hole 322 is the second length, and the first length is greater than the second length. In simpler terms, the length of the second strip-shaped hole (second insertion hole 332) is greater than the length of the first strip-shaped hole (first insertion hole 322).

[0154] Since the first rotating structure 32 is located close to the mounting port 15 and the second rotating structure 33 is located far from the mounting port 15, when the liquid storage tank assembly 31 rotates through the mounting port 15 to enter and exit the liquid storage mounting cavity 12, it mainly rotates around the first axis O1 of the first rotating structure 32 and secondarily around the second axis O2 of the second rotating structure 33. It can be understood that when the liquid storage tank assembly 31 mainly rotates around the first axis O1 of the first rotating structure 32, the second strip hole needs a relatively long length for the second rotating shaft 331 to swing within it, while the length requirement of the first strip hole is relatively short. Therefore, by making the length of the second strip hole (second insertion hole 332) greater than the length of the first strip hole (first insertion hole 322), the length layout of the second strip hole and the first strip hole can be made more reasonable while ensuring that the liquid storage tank assembly 31 can rotate through the mounting port 15 to enter and exit the liquid storage mounting cavity 12. This can avoid the situation where the liquid storage tank assembly 31 cannot rotate due to an unreasonable length layout of the two strip holes.

[0155] In some embodiments, see Figure 11 and Figure 12 , Figure 11 yes Figure 1 Another exploded view of the indoor unit 100 of the air conditioner. Figure 12 yes Figure 11The diagram shows the structure of the indoor unit 100 of the air conditioner after the liquid storage tank assembly 31 is rotated out of the liquid storage installation cavity 12 through the installation port 15. A limiting structure 4 is provided between the housing 1 and the liquid storage tank assembly 31. The limiting structure 4 is used to limit the rotation of the liquid storage tank assembly 31 around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33 within a preset angle.

[0156] By setting the limiting structure 4, the rotation of the liquid storage tank assembly 31 around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33 can be within a preset angle. In this way, the situation where the liquid storage tank assembly 31 falls out of the liquid storage installation cavity 12 due to excessive rotation angle can be avoided.

[0157] There are multiple ways to implement the aforementioned limiting structure 4. In one possible implementation, see [link to relevant documentation]. Figure 12 The limiting structure 4 includes a limiting hole 41, which is disposed on one of the housing 1 and the liquid storage tank assembly 31.

[0158] Specifically, the limiting hole 41 can be provided on the housing 1. Of course, in other embodiments, the limiting hole 41 can also be provided on the liquid storage tank assembly 31. This embodiment does not limit this.

[0159] In some embodiments, see Figure 12 and Figure 13 , Figure 13 yes Figure 12 An exploded view of an indoor unit 100 of an air conditioner shows that the limiting structure 4 also includes a limiting member 42, which is disposed on the other of the housing 1 and the liquid storage tank assembly 31. When the liquid storage tank assembly 31 rotates about the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, the limiting member 42 slides in the limiting hole 41.

[0160] Since the limiting member 42 is inside the limiting hole 41, when the liquid storage tank assembly 31 rotates around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33, the limiting member 42 can only slide within the limiting hole 41. In this way, the limiting hole 41 can limit the swing angle of the limiting member 42, thereby limiting the rotation of the liquid storage tank assembly 31 around the first axis O1 of the first rotating structure 32 or the second axis O2 of the second rotating structure 33 within a preset angle.

[0161] As can be seen, when the limiting structure 4 includes the limiting member 42 and the limiting hole 41, the rotation of the liquid storage tank assembly 31 can be limited within a preset angle by the cooperation of the limiting member 42 and the limiting hole 41. The implementation method is simple and can reduce the cost of the limiting structure 4 to a certain extent.

[0162] The aforementioned limiting member 42 can be a limiting shaft or other possible structures, and this embodiment does not limit it.

[0163] In addition, by allowing the limiting member 42 to slide within the limiting hole 41, the limiting hole 41 can also guide the sliding direction of the limiting member 42, thereby making the rotation of the liquid storage tank assembly 31 smoother and more stable.

[0164] In some embodiments, see Figure 13 The limiting member 42 is higher than the first axis O1 of the first rotating structure 32 and higher than the second axis O2 of the second rotating structure 33 in the vertical direction.

[0165] By positioning the limiting member 42 vertically above the first axis O1 of the first rotating structure 32 and above the second axis O2 of the second rotating structure 33, the limiting member 42 can be offset vertically from the first axis O1 of the first rotating structure 32 and the second axis O2 of the second rotating structure 33, respectively. In this way, the distance between the limiting member 42 and the first axis O1 of the first rotating structure 32 and the second axis O2 of the second rotating structure 33 is greater, thereby better guiding the rotation of the liquid storage tank assembly 31, making the rotation of the liquid storage tank assembly 31 smoother and more stable.

[0166] In some embodiments, see Figure 3 and Figure 14 , Figure 14 yes Figure 3 An exploded view of the liquid storage tank assembly 31, which includes a tank cover 311. The liquid storage tank assembly 31 is rotatably mounted on the housing 1 via a first rotating structure 32 and a second rotating structure 33. A placement cavity 3111 is provided inside the tank cover 311, and a pick-up and drop-out port 3111a communicating with the placement cavity 3111 is provided on the tank cover 311.

[0167] The material of the box cover 311 can be plastic or metal, etc., and this embodiment does not limit the material. The shape of the box cover 311 can be cuboid or cylinder, etc., and this embodiment does not limit the shape of the box cover 311.

[0168] In some embodiments, the liquid storage tank assembly 31 further includes a liquid storage tank 312, which is disposed in the placement cavity 3111, and has an opening 3111a for the liquid storage tank 312 to enter and exit the placement cavity 3111.

[0169] Since the storage tank 312 is located inside the placement cavity 3111, and the inlet / outlet 3111a allows the storage tank 312 to enter and exit the placement cavity 3111, when the water in the storage tank 312 is used up, the storage tank 312 can be taken out directly from the placement cavity 3111 through the inlet / outlet 3111a to be refilled with water. When the water in the storage tank 312 is full, the storage tank 312 can be put back into the placement cavity 3111 through the inlet / outlet 3111a.

[0170] It can be seen that when the housing 311 is provided with a placement cavity 3111 and a take-out port 3111a communicating with the placement cavity 3111 is provided on the housing 311, it is very convenient to add water to the liquid storage tank 312, that is, it makes the water addition to the liquid storage tank 312 very convenient.

[0171] To facilitate the retrieval of the liquid storage tank 312, in some embodiments, a handle 3121 is provided on the liquid storage tank 312. By providing a handle 3121 on the liquid storage tank 312, it becomes very convenient to retrieve the liquid storage tank 312.

[0172] In some embodiments, see Figure 8 and Figure 15 , Figure 15 yes Figure 8 The enlarged view of the indoor unit 100 of the air conditioner at position D shows that the indoor unit 100 also includes a locking device 5, which is disposed on the housing 1. The locking device 5 is used to lock the liquid storage tank assembly 31 in the liquid storage installation cavity 12 when the liquid storage tank assembly 31 is pressed. The locking device 5 is also used to unlock the liquid storage tank assembly 31 when the liquid storage tank assembly 31 is pressed again.

[0173] By providing the locking device 5, when the liquid storage tank assembly 31 presses the locking device 5, it can lock the liquid storage tank assembly 31 into the liquid storage mounting cavity 12, thereby keeping the liquid storage tank assembly 31 within the liquid storage mounting cavity 12. When the liquid storage tank assembly 31 presses the locking device 5 again, it can unlock the liquid storage tank assembly 31, allowing it to exit from the liquid storage mounting cavity 12 through the mounting port 15, so that water can be added to the liquid storage tank 312.

[0174] As can be seen, when the air conditioner indoor unit 100 also includes a locking device 5, the purpose of locking or unlocking the liquid storage tank assembly 31 can be achieved by pressing the locking device 5, and the operation is very simple. Therefore, the complexity of locking and unlocking the liquid storage tank assembly 31 can be simplified.

[0175] The locking device 5 mentioned above can be a push switch or any other possible locking device 5, and this embodiment does not limit it.

[0176] Considering the convenience of pressing the locking device 5, in some embodiments, the vertical height of the locking device 5 can be any value between 695mm and 705mm. Specifically, the vertical height of the locking device 5 can be 695mm, 700mm, or 705mm. In this way, the user does not need to bend over too much when pressing the locking device 5 through the liquid storage tank assembly 31, making pressing the locking device 5 more convenient and more user-friendly.

[0177] In some embodiments, see Figure 1 and Figure 2 The housing 1 includes a front 16, a back 17 and a side 18. The back 17 is arranged opposite to the front 16, and the side 18 is connected between the front 16 and the back 17. The mounting port 15 is provided on the side 18.

[0178] By placing the mounting port 15 on the side 18, compared to placing it on the front, it is more convenient and quick to remove the decorative panel beforehand when rotating the liquid storage tank assembly 31 out of the liquid storage installation cavity 12 through the mounting port 15. Furthermore, it reduces the impact of the mounting port 15 on the appearance of the air conditioner indoor unit 100, thereby improving the aesthetic appeal of the air conditioner indoor unit 100.

[0179] Of course, in some other embodiments, the mounting port 15 is also located on the front side 16. When the mounting port 15 is located on the front side 16, when the liquid storage tank assembly 31 is rotated out of the liquid storage installation cavity 12 through the mounting port 15, there is no need to consider reserving space on the side 18 during the installation of the indoor air conditioner unit. This can minimize the possibility of interference between the liquid storage tank assembly 31 and the surrounding environment, making the selection of the installation location more flexible and adaptable when installing the indoor air conditioner unit.

[0180] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
