Description

Technical Field

[0001] This application relates to the field of air conditioning 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 functional modules of air conditioners, they also have humidification modules for humidifying indoor air.

[0003] However, in related technologies, the installation and disassembly of the liquid storage tank in the humidification module is cumbersome and inefficient. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the related technologies, this application provides an air conditioning indoor unit to solve the problems of cumbersome installation and disassembly of the liquid storage tank and low efficiency in the related technologies.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides an air conditioner indoor unit, which includes:

[0006] The housing has an air conditioning module mounting cavity and a liquid storage tank assembly mounting cavity. The housing is provided with an air inlet and an air outlet that communicate with the air conditioning module mounting cavity. The housing has a front, a back and a side. The front and the back are arranged opposite to each other, and the side is connected between the front and the back.

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

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

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

[0010] A humidification module, comprising a liquid storage tank assembly disposed within a mounting cavity of the liquid storage tank assembly; and a mounting port communicating with the mounting cavity of the liquid storage tank assembly is provided on the front and / or the side, the mounting port being used for the liquid storage tank assembly to enter and exit the mounting cavity of the liquid storage tank assembly.

[0011] In related technologies, the liquid receiver tank is often installed and removed from the back of the indoor unit of an air conditioner. Since the back of the indoor unit is also the back of the casing, and is typically close to the wall, the operating space is limited, making the installation and removal of the liquid receiver tank cumbersome and inefficient. In this application, however, the front and / or side of the casing has an installation port communicating with the liquid receiver tank assembly mounting cavity. This installation port allows the liquid receiver tank assembly to enter and exit the mounting cavity, enabling installation and removal from the port. This means the liquid receiver tank assembly can be installed and removed from the front and / or side of the casing. Furthermore, since the front and side of the indoor unit casing typically have a large distance from the wall, providing sufficient operating space, installing and removing the liquid receiver tank assembly from the front and / or side of the casing facilitates installation and removal, thereby improving efficiency.

[0012] Secondly, this application also provides an indoor air conditioning unit, which includes:

[0013] The housing has an air conditioning module mounting cavity and a liquid storage tank assembly mounting cavity. The housing is provided with an air inlet and an air outlet that communicate with the air conditioning module mounting cavity. The housing has a front, a back and a side. The front and the back are arranged opposite to each other, and the side is connected between the front and the back.

[0014] Air conditioning module, the air conditioning module includes:

[0015] A fan is disposed inside the air conditioning module mounting cavity, and the fan is used to draw air from outside the housing into the air conditioning module mounting cavity through the air inlet;

[0016] A heat exchanger is disposed in the air conditioning module mounting cavity. The heat exchanger is used to exchange heat with the air in the air conditioning module mounting cavity. The fan is also used to blow the heat-exchanged air out of the air conditioning module mounting cavity through the air outlet.

[0017] A humidifying module, the humidifying module including a liquid storage tank assembly; an installation port communicating with the installation cavity of the liquid storage tank assembly is provided on the front and / or the side, the liquid storage tank assembly is used to close the installation port after entering the installation cavity of the liquid storage tank assembly through the installation port, and the liquid storage tank assembly is also used to open the installation port after exiting the installation cavity of the liquid storage tank assembly through the installation port.

[0018] In related technologies, the liquid receiver tank is often installed and removed from the back of the indoor unit of an air conditioner. Since the back of the indoor unit is also the back of the casing, and is typically close to the wall, the operating space is limited, making the installation and removal of the liquid receiver tank cumbersome and inefficient. In this application, however, the front and / or side of the casing has an installation port communicating with the liquid receiver tank assembly mounting cavity. Because the liquid receiver tank assembly can enter and exit the mounting cavity through this port, it can be installed and removed from the installation port, i.e., from the front and / or side of the casing. Furthermore, since the front and side of the indoor unit casing usually have a large distance from the wall, providing sufficient operating space, installing and removing the liquid receiver tank assembly from the front and / or side of the casing facilitates installation and removal, thereby improving efficiency.

[0019] In addition, since the liquid tank assembly is used to close the installation port after entering the installation cavity through the installation port, and also to open the installation port after exiting the installation cavity through the installation port, it not only facilitates the installation and disassembly of the liquid tank assembly, but also ensures the integrity of the appearance of the air conditioner indoor unit after the installation port is closed. The presence of the installation port will not damage the overall design of the air conditioner indoor unit, thus improving the appearance quality of the product.

[0020] Optionally, the liquid storage tank assembly is rotatably mounted on the housing via a rotating structure, so that the liquid storage tank assembly rotates in and out of the liquid storage tank assembly mounting cavity about the rotation axis of the rotating structure.

[0021] This design makes rotation less strenuous than translation or other methods, especially for heavier or larger liquid storage tank assemblies. Rotation only requires overcoming a small amount of friction, without having to lift or drag the entire liquid storage tank assembly. Therefore, it reduces the difficulty of operation for the liquid storage tank assembly when moving in and out of the liquid storage tank assembly mounting cavity, making the operation easier for the user.

[0022] Optionally, the rotating structure is disposed within the housing, and the rotating structure is disposed near the mounting port.

[0023] With this configuration, since the mounting port is located on the side and / or the front, the rotating structure is also located close to the side and / or the front of the casing. This reduces the gap between the liquid tank assembly and the side and / or the front after the liquid tank assembly is installed in the mounting cavity, thereby reducing the space occupied by the liquid tank assembly in the casing and facilitating a more compact design for the indoor air conditioning unit.

[0024] Optionally, the rotating structure includes:

[0025] A rotating shaft, which is disposed on one of the housing and the liquid storage tank assembly;

[0026] An insertion hole is provided on the other of the housing and the liquid storage tank assembly, the insertion hole for the rotating shaft to be inserted and rotatably engaged with the rotating shaft.

[0027] With this configuration, firstly, during the process of the liquid storage tank assembly rotating around the rotating axis to enter and exit the liquid storage tank assembly mounting cavity, the tight fit between the rotating axis and the insertion hole can limit the radial and axial displacement of the liquid storage tank assembly during rotation. This ensures the smoothness of the rotational movement of the liquid storage tank assembly, avoids shaking or swaying, and thus ensures the stability of the operation of the liquid storage tank assembly entering and exiting the liquid storage tank assembly mounting cavity.

[0028] Secondly, since the structure of the rotating shaft and the insertion hole is relatively simple, it is convenient to process and manufacture the rotating structure, which in turn helps to reduce production costs, improve production efficiency, and facilitate large-scale production.

[0029] Finally, during assembly, simply insert the rotating shaft accurately into the corresponding insertion hole to complete the installation. The operation is simple and straightforward, requiring no complicated installation tools or techniques, which reduces assembly time and difficulty and improves product assembly efficiency.

[0030] Optionally, the rotating shaft includes:

[0031] A shaft portion is disposed on the liquid storage tank assembly;

[0032] 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 shaft portion. Each first reinforcing rib plate extends axially along the shaft portion. The multiple first reinforcing rib plates are inserted into the insertion hole and rotatedly engaged with the insertion hole.

[0033] This design, on the one hand, enhances the structural strength of the rotating shaft through multiple first reinforcing ribs, thereby making the rotating shaft less prone to bending or torsion deformation, ensuring the stability and reliability of the rotating shaft, and extending the service life of the rotating shaft.

[0034] On the other hand, by arranging multiple first reinforcing ribs in a circumferentially spaced array on the peripheral wall of the shaft body, the contact area between the rotating shaft and the insertion hole can be reduced. This reduces the friction between the rotating shaft and the inner wall of the insertion hole during rotation, thus reducing the degree of wear.

[0035] Optionally, the liquid storage tank assembly is provided with a plurality of second reinforcing ribs, each of the plurality of second reinforcing ribs corresponding to a plurality of first reinforcing ribs, and each second reinforcing rib is connected to the corresponding first reinforcing rib.

[0036] This design serves two purposes. First, since the second reinforcing rib on the liquid storage tank assembly is connected to the first reinforcing rib, the connection strength between the rotating shaft and the liquid storage tank assembly is enhanced. This helps prevent loosening between the rotating shaft and the liquid storage tank assembly due to long-term rotation, ensuring the stability and reliability of the rotating structure and thus extending its service life.

[0037] On the other hand, when the rotating shaft is under stress, the force on the rotating shaft can be distributed and transmitted to the liquid storage tank assembly through multiple second reinforcing ribs. This can prevent excessive local stress on the liquid storage tank assembly, greatly improve the overall deformation resistance of the liquid storage tank assembly, and reduce the risk of damage when subjected to frequent rotation or external impact.

[0038] Optionally, a rotation limiting structure is provided between the housing and the liquid storage tank assembly, the rotation limiting structure being used to restrict the liquid storage tank assembly from rotating within a preset angle around the rotation axis.

[0039] This design, on the one hand, limits the rotation angle of the liquid storage tank assembly by using a rotation limiting structure, which can prevent it from colliding with other components inside the housing during rotation, thereby preventing damage to other components and avoiding increased maintenance costs.

[0040] On the other hand, the rotation limiting structure ensures that the liquid storage tank assembly stops rotating at a specific position each time, providing the user with a clear positional indication. This eliminates the need for users to rely on intuition to determine if the liquid storage tank assembly has reached the correct position during operation, improving operational accuracy and reliability and reducing problems caused by incomplete rotation.

[0041] Optionally, the rotation limiting structure includes:

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

[0043] A limiting shaft is disposed on the other of the housing and the liquid storage tank assembly. The direction in which the liquid storage tank assembly rotates about the rotation axis is a first direction. The limiting shaft is movably disposed in the limiting hole along the first direction. The limiting shaft and the limiting hole are in a limiting engagement in the first direction.

[0044] With this configuration, firstly, as the liquid storage tank assembly rotates along the first direction, the limiting shaft moves within the limiting hole along the first direction. When the limiting shaft reaches the end of the limiting hole, it prevents the liquid storage tank assembly from continuing to rotate. This achieves precise angular limiting, ensuring that the liquid storage tank assembly can only rotate within a preset angle.

[0045] Secondly, since the structure of the limiting shaft and the limiting hole is relatively simple, it is convenient to process and manufacture the rotating limiting structure, which in turn helps to reduce production costs, improve production efficiency, and facilitate large-scale production.

[0046] Finally, during assembly, simply insert the limit shaft accurately into the corresponding limit hole to complete the installation. The operation is simple and straightforward, requiring no complicated installation tools or techniques, which reduces assembly time and difficulty and improves product assembly efficiency.

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

[0048] A box cover, which is rotatably mounted on the housing via the rotating structure, has a placement cavity inside the box cover and a pick-up / placement port communicating with the placement cavity on the box 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] With this configuration, the liquid storage tank assembly can be rotatably mounted on the housing via the tank cover. This eliminates the need for rotating structures on the liquid storage tank, which simplifies the tank's structure and facilitates its manufacturing. It also helps avoid the influence of rotating structures on the size of the tank's internal cavity, ensuring that the tank has a sufficiently large internal cavity to store liquid.

[0051] On the other hand, since the liquid storage tank is located in the placement cavity inside the tank cover, the tank cover can effectively protect the liquid storage tank from external factors, thereby helping to extend the service life of the liquid storage tank and ensuring its normal use.

[0052] Optionally, the liquid storage tank is provided with a handle structure for lifting the liquid storage tank.

[0053] This design, with its handle structure, facilitates the easy lifting of the liquid storage tank, which in turn facilitates the removal of the liquid storage tank from the placement chamber, or the easy placement of the liquid storage tank into the placement chamber.

[0054] Optionally, the indoor unit of the air conditioner further includes:

[0055] A locking device is disposed on the housing. The locking device is used to lock the liquid storage tank assembly in the mounting cavity of the liquid storage tank assembly when the liquid storage tank assembly is pressed through the locking device. The locking device is also used to unlock the liquid storage tank assembly when the liquid storage tank assembly is pressed through the locking device.

[0056] This design allows for simple and convenient operation, as locking and unlocking can be achieved by pressing the locking device on the liquid storage tank assembly, requiring no additional tools or complicated procedures. This enables users to quickly lock and unlock the liquid storage tank assembly during installation or removal, improving work efficiency.

[0057] In addition, the press-type design allows for one-handed operation, making it convenient for users to operate in situations with limited space or when both hands are not readily available, thus improving the user experience.

[0058] Optionally, the indoor unit of the air conditioner is a cabinet-type indoor unit, and the distance between the locking device and the ground is h, where h ≥ 695 mm and h ≤ 705 mm.

[0059] With this setup, the distance h is roughly within the range that an adult can easily operate with their arms hanging naturally when standing. Therefore, users can easily operate the locking device without having to bend over excessively or stand on tiptoe. This makes locking or unlocking the liquid tank component easier, reducing physical exertion and inconvenience during operation and improving the user experience. Attached Figure Description

[0080] 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.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0084] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0085] As described in the background section of this application, air conditioners are one of the most expandable home appliances, and they integrate more and more functional modules. In addition to the original functional modules of the air conditioner, they also have a humidification module for humidifying indoor air.

[0086] However, in related technologies, when water needs to be added to the liquid storage tank in the humidification module, the decorative panel on the front of the air conditioner needs to be removed before the liquid storage tank can be taken out of the air conditioner for water addition. This makes the removal of the liquid storage tank complicated and inefficient.

[0087] In view of the above-mentioned problems, this application provides an air conditioning indoor unit to solve the problems of complicated removal methods and low removal efficiency of liquid storage tank in related technologies.

[0088] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0089] In some embodiments, such as Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner includes a casing 1, such as Figure 3 As shown, the housing 1 has an air conditioning module mounting cavity and a liquid storage tank assembly mounting cavity 11. The housing 1 is provided with an air inlet and an air outlet communicating with the air conditioning module mounting cavity. Figure 1 and Figure 2 As shown, the housing 1 has a front 12, a back 13 and a side 13. The front 12 and the back 13 are arranged opposite to each other, and the side 13 is connected between the front 12 and the back 13.

[0090] With this configuration, firstly, different air conditioning module mounting cavities and liquid storage tank assembly mounting cavities 11 are formed inside the housing 1. In this way, different functional modules can be separated through different cavities, which can avoid mutual interference between different functional modules and help ensure that different functional modules operate normally.

[0091] Secondly, the air inlet allows indoor air to enter the air conditioning module installation cavity, while the air outlet can return the air treated by the air conditioner to the room, thus forming an effective air circulation system that can continuously regulate indoor air temperature, humidity and other parameters to maintain a comfortable indoor environment.

[0092] In some embodiments, the indoor unit of the air conditioner includes an air conditioning module, which includes a fan disposed within the mounting cavity of the air conditioning module. The fan is used to draw air from outside the casing 1 into the mounting cavity of the air conditioning module through an air inlet. This configuration allows the fan to enable air to enter the mounting cavity of the air conditioning module faster and with a more stable flow rate, which is beneficial for providing a stable and continuous supply of air to be processed into the mounting cavity of the air conditioning module, thereby accelerating the rhythm of the entire indoor air circulation.

[0093] In some embodiments, the air conditioning module includes a heat exchanger disposed within the air conditioning module mounting cavity. The heat exchanger is used to exchange heat with the air within the air conditioning module mounting cavity, and the fan is also used to blow the heat-exchanged air out of the air conditioning module mounting cavity through the air outlet.

[0094] This configuration allows the heat exchanger to directly exchange heat with the air, rapidly changing the air temperature. This enables the indoor unit to quickly adjust the indoor air temperature upon receiving the user's set temperature adjustment command. Consequently, it can raise the indoor temperature in a short time, reducing the waiting time for the room to warm up. Furthermore, this efficient heat exchange process helps meet temperature control needs while avoiding excessive energy consumption.

[0095] In addition, fans can more quickly adjust environmental parameters such as temperature and humidity in different parts of the room, reducing large temperature or humidity differences between different areas of the room.

[0096] In some embodiments, the indoor unit of the air conditioner includes a humidification module, such as Figure 1 , Figure 2 and Figure 4 As shown, the humidification module includes a liquid storage tank assembly 2, such as... Figure 4 As shown, the liquid storage tank assembly 2 is disposed within the liquid storage tank assembly mounting cavity 11. Figure 5 As shown, the front 12 and / or the side 13 are provided with an installation port 14 that communicates with the liquid storage tank assembly mounting cavity 11. The installation port 14 is used for the liquid storage tank assembly 2 to enter and exit the liquid storage tank assembly mounting cavity 11.

[0097] In related technologies, the liquid receiver is installed and removed from the back of the indoor unit of the air conditioner. The back of the indoor unit is also the back of the casing. Since the back is usually close to the wall, the operating space is small, which makes the installation and removal of the liquid receiver troublesome and inefficient. In this application, since the front 12 and / or side 13 of the housing 1 are provided with an installation port 14 that communicates with the liquid storage tank assembly mounting cavity 11, and since the installation port 14 is used for the liquid storage tank assembly 2 to enter and exit the liquid storage tank assembly mounting cavity 11, the liquid storage tank assembly 2 can be installed and removed from the installation port 14, that is, the liquid storage tank assembly 2 can be installed and removed from the front 12 and / or side 13 of the housing 1. Furthermore, since for the indoor unit of the air conditioner, the front 12 and side 13 of its housing 1 usually have a large distance from the wall, that is, there is sufficient operating space, it is beneficial to facilitate the installation and removal of the liquid storage tank assembly 2 when installing and removing the liquid storage tank assembly from the front 12 and / or side 13 of the housing 1, thereby improving the efficiency of installation and removal.

[0098] In some embodiments, such as Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner includes a casing 1, an air conditioning module, and a humidification module. Among them, as... Figure 3 As shown, the housing 1 has an air conditioning module mounting cavity and a liquid storage tank assembly mounting cavity 11. The housing 1 is provided with an air inlet and an air outlet communicating with the air conditioning module mounting cavity. Figure 1 and Figure 2 As shown, the housing 1 has a front 12, a back 13 and a side 13. The front 12 and the back 13 are arranged opposite to each other, and the side 13 is connected between the front 12 and the back 13.

[0099] The air conditioning module includes a fan and a heat exchanger. The fan is located inside the air conditioning module mounting cavity and is used to draw air from outside the housing 1 into the air conditioning module mounting cavity through the air inlet. The heat exchanger is located inside the air conditioning module mounting cavity and is used to exchange heat with the air inside the air conditioning module mounting cavity. The fan is also used to blow the heat-exchanged air out of the air conditioning module mounting cavity through the air outlet.

[0100] like Figure 1 , Figure 2and Figure 4 As shown, the humidification module includes a liquid storage tank assembly 2, such as... Figure 4 As shown, the liquid storage tank assembly 2 is disposed within the liquid storage tank assembly mounting cavity 11. Figure 5 As shown, the front 12 and / or the side 13 are provided with an installation port 14 that communicates with the liquid storage tank assembly mounting cavity 11. The installation port 14 is used for the liquid storage tank assembly 2 to enter and exit the liquid storage tank assembly mounting cavity 11.

[0101] In related technologies, the liquid receiver is installed and removed from the back of the indoor unit of the air conditioner. The back of the indoor unit is also the back of the casing. Since the back is usually close to the wall, the operating space is small, which makes the installation and removal of the liquid receiver troublesome and inefficient. In this application, since the front 12 and / or side 13 of the housing 1 are provided with an installation port 14 that communicates with the liquid storage tank assembly mounting cavity 11, and since the installation port 14 is used for the liquid storage tank assembly 2 to enter and exit the liquid storage tank assembly mounting cavity 11, the liquid storage tank assembly 2 can be installed and removed from the installation port 14, that is, the liquid storage tank assembly 2 can be installed and removed from the front 12 and / or side 13 of the housing 1. Furthermore, since for the indoor unit of the air conditioner, the front 12 and side 13 of its housing 1 usually have a large distance from the wall, that is, there is sufficient operating space, it is beneficial to facilitate the installation and removal of the liquid storage tank assembly 2 when installing and removing the liquid storage tank assembly from the front 12 and / or side 13 of the housing 1, thereby improving the efficiency of installation and removal.

[0102] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the humidification module includes a liquid storage tank assembly 2. Figure 5 As shown, the front 12 and / or side 13 are provided with mounting ports 14 that communicate with the liquid storage tank assembly mounting cavity 11. The liquid storage tank assembly 2 is used to close the mounting port 14 after entering the liquid storage tank assembly mounting cavity 11 through the mounting port 14. Figure 1 and Figure 2 As shown), the reservoir assembly 2 is also used to open the mounting port 14 after exiting the reservoir assembly mounting cavity 11 through the mounting port 14.

[0103] In related technologies, the liquid receiver is installed and removed from the back of the indoor unit of the air conditioner. The back of the indoor unit is also the back of the casing. Since the back is usually close to the wall, the operating space is small, which makes the installation and removal of the liquid receiver troublesome and inefficient. In this application, since the front 12 and / or side 13 of the housing 1 are provided with an installation port 14 that communicates with the liquid storage tank assembly mounting cavity 11, and since the liquid storage tank assembly 2 can enter and exit the liquid storage tank assembly mounting cavity 11 through the installation port 14, the liquid storage tank assembly 2 can be installed and removed from the installation port 14, that is, the liquid storage tank assembly 2 can be installed and removed from the front 12 and / or side 13 of the housing 1. Furthermore, since the front 12 and side 13 of the housing 1 of the air conditioner indoor unit usually have a large distance from the wall, that is, there is sufficient operating space, it is beneficial to facilitate the installation and removal of the liquid storage tank assembly 2 when installing and removing the liquid storage tank assembly from the front 12 and / or side 13 of the housing 1, thereby improving the efficiency of installation and removal.

[0104] In addition, since the liquid storage tank assembly 2 is used to close the mounting port 14 after entering the liquid storage tank assembly mounting cavity 11 through the mounting port 14, and also to open the mounting port 14 after exiting the liquid storage tank assembly mounting cavity 11 through the mounting port 14, it not only facilitates the installation and disassembly of the liquid storage tank assembly 2, but also ensures the integrity of the appearance of the air conditioner indoor unit after the liquid storage tank assembly 2 closes the mounting port 14. The presence of the mounting port 14 will not damage the overall design of the air conditioner indoor unit, thus improving the appearance quality of the product.

[0105] In some embodiments, such as Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner includes a casing 1, an air conditioning module, and a humidification module. Among them, as... Figure 3 As shown, the housing 1 has an air conditioning module mounting cavity and a liquid storage tank assembly mounting cavity 11. The housing 1 is provided with an air inlet and an air outlet communicating with the air conditioning module mounting cavity. Figure 1 and Figure 2 As shown, the housing 1 has a front 12, a back 13 and a side 13. The front 12 and the back 13 are arranged opposite to each other, and the side 13 is connected between the front 12 and the back 13.

[0106] The air conditioning module includes a fan and a heat exchanger. The fan is located inside the air conditioning module mounting cavity and is used to draw air from outside the housing 1 into the air conditioning module mounting cavity through the air inlet. The heat exchanger is located inside the air conditioning module mounting cavity and is used to exchange heat with the air inside the air conditioning module mounting cavity. The fan is also used to blow the heat-exchanged air out of the air conditioning module mounting cavity through the air outlet.

[0107] like Figure 1 , Figure 2 and Figure 4 As shown, the humidification module includes a liquid storage tank assembly 2. Figure 5 As shown, the front 12 and / or side 13 are provided with mounting ports 14 that communicate with the liquid storage tank assembly mounting cavity 11. The liquid storage tank assembly 2 is used to close the mounting port 14 after entering the liquid storage tank assembly mounting cavity 11 through the mounting port 14. Figure 1 and Figure 2 As shown), the reservoir assembly 2 is also used to open the mounting port 14 after exiting the reservoir assembly mounting cavity 11 through the mounting port 14.

[0108] In related technologies, the liquid receiver is installed and removed from the back of the indoor unit of the air conditioner. The back of the indoor unit is also the back of the casing. Since the back is usually close to the wall, the operating space is small, which makes the installation and removal of the liquid receiver troublesome and inefficient. In this application, since the front 12 and / or side 13 of the housing 1 are provided with an installation port 14 that communicates with the liquid storage tank assembly mounting cavity 11, and since the liquid storage tank assembly 2 can enter and exit the liquid storage tank assembly mounting cavity 11 through the installation port 14, the liquid storage tank assembly 2 can be installed and removed from the installation port 14, that is, the liquid storage tank assembly 2 can be installed and removed from the front 12 and / or side 13 of the housing 1. Furthermore, since the front 12 and side 13 of the housing 1 of the air conditioner indoor unit usually have a large distance from the wall, that is, there is sufficient operating space, it is beneficial to facilitate the installation and removal of the liquid storage tank assembly 2 when installing and removing the liquid storage tank assembly from the front 12 and / or side 13 of the housing 1, thereby improving the efficiency of installation and removal.

[0109] In addition, since the liquid storage tank assembly 2 is used to close the mounting port 14 after entering the liquid storage tank assembly mounting cavity 11 through the mounting port 14, and also to open the mounting port 14 after exiting the liquid storage tank assembly mounting cavity 11 through the mounting port 14, it not only facilitates the installation and disassembly of the liquid storage tank assembly 2, but also ensures the integrity of the appearance of the air conditioner indoor unit after the liquid storage tank assembly 2 closes the mounting port 14. The presence of the mounting port 14 will not damage the overall design of the air conditioner indoor unit, thus improving the appearance quality of the product.

[0110] In a preferred embodiment, such as Figure 5 As shown, the mounting port 14 is located on the side 13. With this configuration, the side 13 of the housing 1 has lower requirements for aesthetic appearance and is usually not equipped with decorative panels. Therefore, when installing and removing the liquid storage tank assembly 2 from the side 13 of the housing 1, there is no need to install and remove decorative panels, which simplifies the installation and removal of the liquid storage tank assembly 2 and further improves the efficiency of installation and removal of the liquid storage tank assembly 2.

[0111] In some embodiments, such as Figure 4 As shown, the liquid storage tank assembly 2 is rotatably mounted on the housing 1 via the rotating structure 3, so that the liquid storage tank assembly 2 rotates in and out of the liquid storage tank assembly mounting cavity 11 around the rotation axis of the rotating structure 3.

[0112] With this configuration, rotation is generally less strenuous than translation or other methods, especially for some heavier or larger liquid storage tank assemblies 2. When rotating, only a small frictional force needs to be overcome, without having to lift or drag the entire liquid storage tank assembly 2 completely. Therefore, the operation of the liquid storage tank assembly 2 entering and exiting the liquid storage tank assembly mounting cavity 11 can reduce the difficulty of operation for users and make the operation easier.

[0113] In some embodiments, such as Figure 4 As shown, the rotating structure 3 is disposed inside the housing 1, and the rotating structure 3 is disposed near the mounting port 14.

[0114] With this configuration, since the mounting port 14 is located on the side 13 and / or the front 12, the rotating structure 3 is also located close to the side 13 and / or the front 12 of the housing 1. This reduces the gap between the liquid storage tank assembly 2 and the side 13 and / or the front 12 after the liquid storage tank assembly 2 is installed in the liquid storage tank assembly mounting cavity 11. This helps to reduce the space occupied by the liquid storage tank assembly 2 in the housing 1 and facilitates a compact design of the air conditioning indoor unit.

[0115] In some embodiments, such as Figure 3 and Figure 6 As shown, the rotating structure 3 includes a rotating shaft 31 and an insertion hole 32. The rotating shaft 31 is disposed on one of the housing 1 and the liquid storage tank assembly 2, and the insertion hole 32 is disposed on the other of the housing 1 and the liquid storage tank assembly 2. The insertion hole 32 allows the rotating shaft 31 to be inserted and rotates with the rotating shaft 31.

[0116] With this configuration, firstly, during the process of the liquid storage tank assembly 2 rotating around the rotating shaft 31 to enter and exit the liquid storage tank assembly mounting cavity 11, the tight fit between the rotating shaft 31 and the insertion hole 32 can limit the radial and axial displacement of the liquid storage tank assembly 2 during rotation, thereby ensuring the smoothness of the rotational movement of the liquid storage tank assembly 2 and preventing shaking or swaying, thus ensuring the stability of the operation of the liquid storage tank assembly 2 entering and exiting the liquid storage tank assembly mounting cavity 11.

[0117] Secondly, since the structure of the rotating shaft 31 and the insertion hole 32 is relatively simple, it is convenient to process and manufacture the rotating structure 3, which in turn helps to reduce production costs, improve production efficiency, and facilitate large-scale production.

[0118] Finally, during assembly, simply insert the rotating shaft 31 accurately into the corresponding insertion hole 32 to complete the installation. The operation is simple and straightforward, requiring no complicated installation tools or techniques, which reduces assembly time and difficulty and improves product assembly efficiency.

[0119] In this embodiment, the insertion hole 32 can be a blind hole or a through hole. The structure of the insertion hole 32 is flexible and can be set according to actual needs. This embodiment does not limit it in this respect.

[0120] In some embodiments, the indoor unit of the air conditioner is a cabinet-type indoor unit, and as follows: Figure 4 As shown, in the height direction of the indoor unit of the air conditioner (e.g.) Figure 4 The rotating shaft 31 is located at the lower end of the liquid storage tank assembly 2 in the Z direction.

[0121] This design allows the liquid storage tank assembly 2 to have a lower center of gravity during rotation. When the liquid storage tank assembly 2 is full of liquid, the lower center of gravity also helps the liquid storage tank assembly 2 to remain stable and prevent it from tipping over, effectively reducing the risk of tipping over due to an excessively high center of gravity.

[0122] On the other hand, it can also reduce the space occupied by the liquid storage tank assembly 2 in the housing 1 when rotating, which not only helps to achieve a compact design of the air conditioner indoor unit, but also effectively avoids interference between the liquid storage tank assembly 2 and other components in the housing 1.

[0123] In some embodiments, in the height direction of the indoor unit of the air conditioner (e.g.) Figure 4 The rotating shaft 31 can be set at any position, such as the middle or lower part of the liquid storage tank assembly 2, in the Z direction. The setting position of the rotating shaft 31 on the liquid storage tank assembly 2 is relatively flexible. Specifically, it can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0124] In some embodiments, the rotating structure 3 includes a bearing, which includes an inner ring and an outer ring, and the inner ring and the outer ring are respectively disposed on the housing 1 and the liquid storage tank assembly 2.

[0125] With this configuration, the rolling friction of the bearing can greatly reduce the friction during rotation, thus making the rotation of the liquid storage tank assembly 2 easier and less strenuous, reducing the difficulty of rotation operation.

[0126] In some embodiments, the rotating structure 3 can be any other structure that enables the liquid storage tank assembly 2 to be rotatably disposed on the housing 1. The structure of the rotating structure 3 is flexible and can be configured according to actual needs. This application embodiment does not specifically limit this.

[0127] In some embodiments, such as Figure 6 and Figure 7As shown, the rotating shaft 31 includes a shaft body 311 and first reinforcing ribs 312. The shaft body 311 is disposed on the liquid storage tank assembly 2. Multiple first reinforcing ribs 312 are arranged in a circumferentially spaced array on the peripheral wall of the shaft body 311. Each first reinforcing rib 312 extends axially along the shaft body 311. Figure 6 As shown, multiple first reinforcing ribs 312 are inserted into the insertion hole 32 and rotate with the insertion hole 32.

[0128] This design, on the one hand, enhances the structural strength of the rotating shaft 31 through multiple first reinforcing ribs 312, thereby making the rotating shaft 31 less prone to bending or torsion deformation, ensuring the stability and reliability of the rotating shaft 31, and extending the service life of the rotating shaft 31.

[0129] On the other hand, by arranging multiple first reinforcing ribs 312 in a circumferentially spaced array along the circumferential wall of the shaft portion 311, the contact area between the rotating shaft 31 and the insertion hole 32 can be reduced. In this way, the rotating shaft 31 can reduce the friction between itself and the inner wall of the insertion hole 32 during rotation, thereby reducing the degree of wear.

[0130] In some embodiments, the rotating shaft 31 is a cylinder, meaning that the peripheral wall of the rotating shaft 31 is a complete and uninterrupted cylindrical surface. This configuration simplifies the structure of the rotating shaft 31 and facilitates its processing and manufacturing.

[0131] In some embodiments, such as Figure 7 As shown, the liquid storage tank assembly 2 is provided with a plurality of second reinforcing ribs 4, and the plurality of second reinforcing ribs 4 correspond one-to-one with a plurality of first reinforcing ribs 312, with each second reinforcing rib 4 connected to the corresponding first reinforcing rib 312.

[0132] This design serves several purposes. First, since the second reinforcing rib 4 on the liquid storage tank assembly 2 is connected to the first reinforcing rib 312, the connection strength between the rotating shaft 31 and the liquid storage tank assembly 2 is enhanced through the second reinforcing rib 4. This helps prevent loosening between the rotating shaft 31 and the liquid storage tank assembly 2 due to long-term rotation, ensuring the stability and reliability of the rotating structure 3, and thus extending its service life.

[0133] On the other hand, when the rotating shaft 31 is subjected to force, the force on the rotating shaft 31 can be distributed and transmitted to the liquid storage tank assembly 2 through multiple second reinforcing ribs 4. This can prevent excessive local stress on the liquid storage tank assembly 2, greatly improve the overall deformation resistance of the liquid storage tank assembly 2, and reduce the risk of damage when frequently rotated or subjected to external impact.

[0134] In some embodiments, such as Figure 8As shown, a rotation limiting structure 5 is provided between the housing 1 and the liquid storage tank assembly 2. The rotation limiting structure 5 is used to restrict the liquid storage tank assembly 2 from rotating within a preset angle around the aforementioned rotation axis.

[0135] This configuration serves two purposes. First, by limiting the rotation angle of the liquid storage tank assembly 2 through the rotation limiting structure 5, it can prevent it from colliding with other components inside the housing 1 during rotation, thereby preventing damage to other components and avoiding increased maintenance costs.

[0136] On the other hand, the rotation limiting structure 5 ensures that the liquid storage tank assembly 2 stops rotating at a specific position each time, providing the user with a clear position indicator. This eliminates the need for the user to rely on intuition to determine whether the liquid storage tank assembly 2 has reached the correct position during operation, improving the accuracy and reliability of the operation and reducing problems caused by incomplete rotation.

[0137] In some embodiments, such as Figure 3 and Figure 8 As shown, the rotation limiting structure 5 includes a limiting hole 51 and a limiting shaft 52. The limiting hole 51 is disposed on one of the housing 1 and the liquid storage tank assembly 2, and the limiting shaft 52 is disposed on the other of the housing 1 and the liquid storage tank assembly 2. The direction of rotation of the liquid storage tank assembly 2 around the aforementioned rotation axis is a first direction (e.g., ...). Figure 8 In the B direction), the limiting shaft 52 is movably disposed in the limiting hole 51 along the first direction, and the limiting shaft 52 and the limiting hole 51 are engaged in the upper limit cooperation in the first direction.

[0138] With this configuration, firstly, as the liquid storage tank assembly 2 rotates along the first direction, the limiting shaft 52 moves along the first direction within the limiting hole 51. When the limiting shaft 52 reaches the end of the limiting hole 51, it will prevent the liquid storage tank assembly 2 from continuing to rotate. This achieves precise angular limiting, ensuring that the liquid storage tank assembly 2 can only rotate within a preset angle.

[0139] Secondly, since the structure of the limiting shaft 52 and the limiting hole 51 is relatively simple, it is convenient to process and manufacture the rotating limiting structure 5, which in turn helps to reduce production costs, improve production efficiency, and facilitate large-scale production.

[0140] Finally, during assembly, simply insert the limiting shaft 52 accurately into the corresponding limiting hole 51 to complete the installation. The operation is simple and straightforward, requiring no complicated installation tools or techniques, which reduces assembly time and difficulty and improves product assembly efficiency.

[0141] In some embodiments, the rotation limiting structure 5 includes a cam and a limiting block, wherein the cam is mounted on the liquid storage tank assembly 2 and the limiting block is mounted on the housing 1. The cam rotates together with the liquid storage tank assembly 2, and when the cam rotates to a specific position, it contacts the limiting block, thereby limiting the rotation of the liquid storage tank assembly 2 within a preset angle.

[0142] With this configuration, the contact force between the cam and the limit block is large, which can withstand a large rotational torque, thus ensuring the reliability of the rotational limit of the liquid storage tank assembly 2.

[0143] In some embodiments, the rotation limiting structure 5 can also be any other structure that restricts the rotation of the liquid storage tank assembly 2 within a preset angle. The structure of the rotation limiting structure 5 is flexible and can be set according to actual needs. This application embodiment does not specifically limit this.

[0144] In some embodiments, such as Figure 4 and Figure 9 As shown, the liquid storage tank assembly 2 includes a tank cover 21 and a liquid storage tank 22, wherein the tank cover 21 is rotatably mounted on the housing 1 via a rotating structure 3, as shown. Figure 10 As shown, the box cover 21 is provided with a placement cavity 211, such as Figure 11 As shown, the box cover 21 is provided with a loading / unloading port 212 that communicates with the placement cavity 211. For example... Figure 4 As shown, the liquid storage tank 22 is disposed in the placement cavity 211, and the access port 212 allows the liquid storage tank 22 to enter and exit the placement cavity 211.

[0145] With this configuration, on the one hand, the liquid storage tank assembly 2 can be rotatably mounted on the housing 1 via the tank cover 21, so there is no need to set the rotating structure 3-related structure on the liquid storage tank 22. This simplifies the structure of the liquid storage tank 22, facilitates the processing and manufacturing of the liquid storage tank 22, and also helps to avoid the influence of the rotating structure 3-related structure on the size of the inner cavity of the liquid storage tank 22, thus ensuring that the liquid storage tank 22 has a sufficiently large inner cavity to store liquid.

[0146] On the other hand, since the liquid storage tank 22 is located in the placement cavity 211 inside the cover 21, the cover 21 can effectively protect the liquid storage tank 22 from external factors, thereby helping to extend the service life of the liquid storage tank 22 and ensuring its normal use.

[0147] In this embodiment, the liquid storage tank 22 is used to store liquid for the humidification module to humidify the indoor air, ensuring the normal operation of the humidification function of the humidification module. The liquid stored in the liquid storage tank 22 can be purified water, an aqueous solution containing antibacterial agents, or an aqueous solution containing aromatherapy agents, etc. The type of liquid can be selected flexibly, and can be selected according to actual needs. This embodiment does not impose specific limitations on this.

[0148] In some embodiments, such as Figure 11 As shown, the rotating shaft 31 in the rotating structure 3 and the limiting shaft 52 in the rotating limiting structure 5 are both located on the tank cover 21. This arrangement facilitates the installation of the rotating shaft 31 and the limiting shaft 52 on the liquid storage tank assembly 2.

[0149] In some embodiments, the liquid storage tank assembly 2 includes only a liquid storage tank 22. In this case, the liquid storage tank 22 is rotatably mounted on the housing 1 via a rotating structure 3, and a rotation limiting structure 5 is disposed between the liquid storage tank 22 and the housing 1. This configuration simplifies the structure of the liquid storage tank assembly 2 and facilitates its manufacturing and assembly.

[0150] In some embodiments, such as Figure 12 As shown, the liquid storage tank 22 is provided with a handle structure 221, which is used to lift the liquid storage tank 22.

[0151] This design, through the handle structure 221, facilitates the lifting of the liquid storage tank 22, which in turn facilitates the removal of the liquid storage tank 22 from the placement cavity 211, or facilitates the placement of the liquid storage tank 22 into the placement cavity 211.

[0152] In some embodiments, such as Figure 12 As shown, the handle structure 221 includes a groove 2211 and a lifting plate 2212. The groove 2211 is recessed on the outer surface of the liquid storage tank 22, and the lifting plate 2212 is disposed in the groove 2211. The lifting plate 2212 is approximately perpendicular to the bottom wall of the groove 2211. Both the lifting plate 2212 and the inner wall of the groove 2211 can be used to lift the liquid storage tank 22.

[0153] With this configuration, since the groove 2211 is recessed on the outer surface of the liquid storage tank 22 and the lifting plate 2212 is located inside the groove 2211, the handle structure 221 will not protrude from the outer surface of the liquid storage tank 22. This reduces the space occupied by the liquid storage tank 22, which is conducive to achieving a compact design of the liquid storage tank assembly 2.

[0154] In some embodiments, the handle structure 221 includes a handle rod, which is U-shaped or C-shaped, and both ends of the handle rod are disposed on the liquid storage tank 22. This arrangement simplifies the specific structure of the handle structure 221 to a certain extent and facilitates its installation on the liquid storage tank 22.

[0155] In some embodiments, such as Figure 4As shown, the indoor unit of the air conditioner also includes a locking device 6, which is disposed on the housing 1. The locking device 6 is used to lock the liquid storage tank assembly 2 in the liquid storage tank assembly mounting cavity 11 when the liquid storage tank assembly 2 is pressed by the locking device 6. The locking device 6 is also used to unlock the liquid storage tank assembly 2 when the liquid storage tank assembly 2 is pressed by the locking device 6.

[0156] This design allows for simple and convenient operation, as locking and unlocking can be achieved by pressing the locking device 6 on the liquid storage tank assembly 2, requiring no additional tools or complicated procedures. This enables users to quickly lock and unlock the liquid storage tank assembly 2 during installation or removal, improving work efficiency.

[0157] In addition, the press-type design allows for one-handed operation, making it convenient for users to operate in situations with limited space or when both hands are not readily available, thus improving the user experience.

[0158] In some embodiments, the locking device 6 is a push-button latch, such as... Figure 4 As shown, the locking device 6 includes a torsion spring, a rotating shaft, and a latch 61. The torsion spring is sleeved on the rotating shaft, with one end connected to the housing of the locking device 6 and the other end connected to the latch 61. The housing 21 has a slot 213 for inserting the latch 61.

[0159] When the locking device 6 is pressed by the liquid tank assembly 2, the latch 61 will engage with the slot 213 under the action of the torsion spring, thereby locking the liquid tank assembly 2 within the liquid tank assembly mounting cavity 11. When the locking device 6 is pressed again by the liquid tank assembly 2, the latch 61 will gradually disengage from the slot 213 as the liquid tank assembly 2 rotates outward from the liquid tank assembly mounting cavity 11 under the action of the torsion spring, thereby unlocking the liquid tank assembly 2.

[0160] With this configuration, the liquid storage tank assembly 2 can be reliably locked and unlocked using a push-button latch. Moreover, the push-button latch has a low failure rate and is also relatively inexpensive.

[0161] In some embodiments, such as Figure 4 As shown, the locking device 6 and the rotating structure 3 are in the height direction of the indoor unit of the air conditioner (e.g., Figure 4 The components are spaced apart in the Z direction, and when the locking device 6 is pressed by the liquid storage tank assembly 2, the direction of the pressing force is perpendicular to the height direction.

[0162] This design prevents the locking device 6, which is a press-type buckle, from jamming with the liquid storage tank assembly 2, thus helping to prevent the locking device 6 from malfunctioning and ensuring its normal operation.

[0163] In some embodiments, the locking device 6 is a spring-lock type locking device, which includes a spring and a latch. The spring provides elastic force to keep the latch in the locked position. The reservoir assembly 2 has a locking hole for the latch to be inserted. When the locking device 6 is pressed through the reservoir assembly 2, the spring pushes the latch into the locking hole, locking the reservoir assembly 2. When the reservoir assembly 2 is pressed again, the external force compresses the spring, causing the latch to disengage from the locking hole, thus unlocking the reservoir.

[0164] With this configuration, the spring-type locking device can not only reliably lock and unlock the liquid storage tank assembly 2, but also has a lower cost.

[0165] In some embodiments, the indoor unit of the air conditioner is a cabinet-type indoor unit, such as... Figure 4 As shown, the distance between the locking device 6 and the ground is h, where h ≥ 695 mm and h ≤ 705 mm.

[0166] With this setup, the distance h is roughly within the range that an adult can easily operate with their arms hanging naturally when standing. Therefore, users can easily operate the locking device 6 without having to bend over excessively or stand on tiptoe. This makes locking or unlocking the liquid storage tank assembly 2 relatively easy, reducing physical exertion and inconvenience during operation and improving the user experience.

[0167] In this embodiment, the distance h between the locking device 6 and the ground can be any value within the range of 695mm, 705mm, 700mm or 695mm-705mm. The size of the distance h is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not make specific limitations on this.

[0168] 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.
