air conditioner

[0001] This application claims priority to Chinese patent application No. 202410504257.4, filed on April 24, 2024; and Chinese patent application No. 202510391832.9, filed on March 29, 2025; and Chinese patent application No. 202520583499.7, filed on March 29, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0003] An air conditioner typically consists of main components such as a compressor, an outdoor heat exchanger, an indoor heat exchanger, and a fan. The compressor drives the refrigerant circulation, the outdoor and indoor heat exchangers act as condensers and evaporators for heat release and absorption, respectively, and the fan accelerates airflow to enhance heat exchange efficiency. Summary of the Invention

[0004] This invention aims to solve the problem of fixing the air inlet and outlet pipes of air conditioners.

[0005] This disclosure provides an air conditioner comprising: a housing forming the outer casing of the air conditioner; an internal receiving space formed within the housing; a refrigerant circulation loop disposed within the receiving space, the refrigerant circulation loop including a compressor, an outdoor heat exchanger, and an indoor heat exchanger connected end-to-end; an outdoor fan assembly disposed within the receiving space, the air outlet of the outdoor fan assembly facing the outdoor heat exchanger; an air inlet duct for introducing outdoor air; an air outlet duct for exhausting air to the outside; and a mounting base disposed on the outer wall of the housing, the mounting base having adjacently arranged first mounting brackets. The unit comprises an air inlet and a second mounting port; the first mounting port is connected to the air inlet end of the outdoor fan assembly, and the second mounting port is connected to the accommodating space; a mounting base is disposed outside the housing, and the mounting base is used for mounting on a wall or window; wherein, the first end of the air inlet pipe is fixedly provided with a first connector, and the first connector is rotatably connected to the first mounting port; the first end of the air outlet pipe is fixedly provided with a second connector, and the second connector is rotatably connected to the second mounting port; the second end of the air inlet pipe is fixedly connected to the mounting base, and the second end of the air outlet pipe is fixedly connected to the mounting base.

[0006] The above-described technical solution utilizes a mounting base with adjacent first and second mounting ports. A first connector allows the first end of the air inlet pipe to be rotatably connected to the first mounting port, and a second connector allows the first end of the air outlet pipe to be rotatably connected to the second mounting port. The second ends of the air inlet and outlet pipes are then fixed to the mounting base, facilitating installation. When the mounting base is installed on a cavity wall or window, adjusting its position and angle causes the air inlet and outlet pipes to rotate. The first end of the air inlet pipe rotates at the first mounting port, and the first end of the air outlet pipe rotates at the second mounting port, simplifying installation. Regardless of whether the mounting base is installed horizontally or vertically, there is no need to disassemble the air inlet and outlet pipes. Separate installation of the air inlet and outlet pipes is not required after the mounting base is installed; installation can be completed in one go. The installation angle is adjustable, eliminating the need for secondary adjustments, significantly improving installation efficiency and user experience. Attached Figure Description

[0025] The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0026] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure.

Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0027] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0028] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. The term "connected" should be interpreted broadly; for example, a "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. The term "coupled" indicates that two or more components have direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

[0029] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0030] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0031] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0032] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0033] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0034] In air conditioners, there are usually two components: an air inlet duct and an air outlet duct. The air inlet duct draws in outdoor air to exchange heat with the outdoor heat exchanger, and the air is then discharged outdoors through the air outlet duct. The air inlet and air outlet ducts are usually installed side by side, but they need to be installed separately on the window during installation, which is complicated.

[0035] To address the aforementioned problems, as shown in Figures 1 and 2, some embodiments of this disclosure provide an air conditioner that may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner. The interior of the housing 1 may be used to provide installation space.

[0036] As shown in Figure 1, in some embodiments, the housing 1 can adopt a hollow cuboid structure. The length of the housing 1 can be arranged along the height direction, so that the air conditioner can be installed vertically in the usage site, increasing the height of the air conditioner and reducing the space occupied by the air conditioner.

[0037] It should be noted that in other embodiments, the external shape of the housing 1 can be designed as needed, and no limitation is made here.

[0038] As shown in Figures 1 and 3, in some embodiments, the housing 1 may include a main housing 11. The main housing 11 may extend along the height direction. The height dimension of the main housing 11 may be greater than the left-right width dimension and the front-back width dimension of the main housing 11, so as to increase the height of the housing 1 and reduce the space occupied by the housing 1.

[0039] As shown in Figures 1 and 3, in some embodiments, the housing 1 may include a chassis 12. The chassis 12 may be located at the bottom of the main housing 11. A receiving space 10 may be formed between the top of the chassis 12 and the interior of the main housing 11. This receiving space 10 is used as a mounting space for other components of the air conditioner.

[0040] As shown in Figures 1 and 3, in some embodiments, the chassis 12 may be provided with feet 13 on its periphery. The feet 13 may extend outward from the chassis 12, and the feet 13 may be used to increase the contact area between the bottom of the casing 1 and the ground, thereby improving the reliability of the chassis 12 in supporting the air conditioner and improving the stability of the air conditioner.

[0041] As shown in Figures 1 and 3, in some embodiments, multiple feet 13 can be provided, and the multiple feet 13 can be connected end to end, so that the multiple feet 13 are arranged circumferentially around the periphery of the chassis 12. In this way, the multiple feet 13 can form a ring structure on the outer periphery of the chassis 12, which improves the structural strength between the multiple feet 13 and forms a complete ring structure; at the same time, it avoids the feet 13 from bumping into the user and improves the safety of the air conditioner.

[0042] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop may be located within the accommodating space 10. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 can respectively function as a condenser and an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0043] Specifically, in the refrigeration cycle, the outdoor heat exchanger 22 can act as a condenser, and the indoor heat exchanger 23 can act as an evaporator. In the heating cycle, the outdoor heat exchanger 22 can act as an evaporator, and the indoor heat exchanger 23 can act as a condenser.

[0044] It should be noted that both the refrigeration and heating cycles involve a series of processes, including compression, condensation, expansion, and evaporation, and the supply of refrigerant to the conditioned and heat-exchanged air.

[0045] Compressor 21 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0046] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0047] The evaporator evaporates the expanded refrigerant and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor 21. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0048] Throughout the cycle, the air conditioner can regulate the temperature of the indoor space, improve the comfort of the indoor space, and enhance the user experience.

[0049] As shown in Figures 2, 3, and 4, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be housed within the casing 1. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used to introduce outdoor air into the casing 1 for heat exchange with the outdoor heat exchanger 22, forming a heat exchange airflow.

[0050] For example, during the cooling cycle, the outdoor heat exchanger 22 acts as a condenser, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to dissipate heat and lower its temperature. During the heating cycle, the outdoor heat exchanger 22 acts as an evaporator, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to raise its temperature.

[0051] As shown in Figures 1, 2, and 3, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be disposed within the housing 1. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used to introduce indoor air into the housing 1 for heat exchange with the indoor heat exchanger 23, forming a heat exchange airflow.

[0052] For example, during the refrigeration cycle, the indoor heat exchanger 23 acts as an evaporator, and the indoor fan assembly 4 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, thereby reducing the temperature of the air flowing through the indoor heat exchanger 23 and blowing the cooled air back into the room to lower the indoor air temperature.

[0053] For example, during the heating cycle, the indoor heat exchanger 23 acts as a condenser, and the outdoor fan assembly 3 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, raising the temperature of the air flowing through the indoor heat exchanger 23, and then blowing the heated air back into the room to raise the indoor air temperature.

[0054] As shown in Figures 3 and 4, in some embodiments, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be respectively housed in the receiving space 10 inside the casing 1. In this way, the casing 1 can cover and protect them, preventing the erosion of foreign objects or the impact of external forces from causing structural damage, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.

[0055] As shown in Figures 3 and 4, in some embodiments, the internal accommodating space 10 of the casing 1 may include three sub-spaces. These three sub-spaces are, from bottom to top, a first sub-space 110, a second sub-space 120, and a third sub-space 130. The compressor 21 can be housed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be housed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 can be housed in the third sub-space 130. Thus, by using three layers of sub-spaces from bottom to top, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be distributed at different heights within the casing 1, which helps to increase the overall height of the air conditioner, reduce its width and thickness, and minimize the space occupied by the air conditioner in the operating area.

[0056] As shown in Figures 2, 3, and 4, in some embodiments, an indoor air inlet 111 may be provided on the outer wall of the casing 1. The indoor air inlet 111 can connect to the outside of the casing 1. The indoor air inlet 111 can connect to the indoor space. The indoor air inlet 111 can be located on the outer wall corresponding to the third subspace 130, and the indoor air inlet 111 can be arranged opposite to the air inlet end of the indoor heat exchanger 23 and the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 can draw indoor air into the casing 1 through the indoor air inlet 111 to exchange heat with the indoor heat exchanger 23, and the heat-exchanged air is discharged back into the indoor space outside the casing 1 through the air outlet end of the indoor fan assembly 4.

[0057] As shown in Figures 1, 3, and 4, in some embodiments, an indoor air outlet 112 may be provided on the outer wall of the housing 1. The indoor air outlet 112 may connect to the outside of the housing 1. The indoor air outlet 112 may connect to the indoor space. The indoor air outlet 112 may be located on the outer wall corresponding to the third subspace 130, and the indoor air outlet 112 may be arranged opposite to the air outlet end of the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 draws indoor air through the indoor air inlet 111, exchanges heat with the indoor heat exchanger 23, and then discharges it back into the indoor space outside the housing 1 through the air outlet end and indoor air outlet 112 of the indoor fan assembly 4.

[0058] As shown in Figures 1 and 3, in some embodiments, an air guide plate 113 may be provided on the outer wall of the housing 1. The air guide plate 113 is rotatably disposed at the indoor air outlet 112. Multiple air guide plates 113 may be provided, and multiple air guide plates 113 may be arranged side by side at the indoor air outlet 112. When the air guide plate 113 rotates, it can open or close the indoor air outlet 112. When the air guide plate 113 rotates to open the indoor air outlet 112, it can also change the air outlet direction of the indoor air outlet 112.

[0059] As shown in Figures 2 and 4, in some embodiments, the air conditioner may include an air inlet duct 14. The air inlet duct 14 may be located in the space outside the casing 1. The air inlet duct 14 can be used to introduce outdoor air. One end of the air inlet duct 14 can be connected to the air inlet end of the outdoor fan assembly 3. The other end of the air inlet duct 14 can be used to connect to the outdoor space. The air outlet end of the outdoor fan assembly 3 can be arranged towards the outdoor heat exchanger 22. Thus, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, introduce the outdoor air into the casing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool it.

[0060] As shown in Figures 2 and 4, in some embodiments, the air conditioner may include an air outlet duct 15. The air outlet duct 15 may be located in the space outside the casing 1. The air outlet duct 15 can be used to exhaust air to the outside, discharging air from inside the casing 1 to the outside. One end of the air outlet duct 15 may communicate with the internal space of the casing 1. The other end of the air outlet duct 15 may communicate with the outdoor space. Thus, when the outdoor fan assembly 3 is operating, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, introducing outdoor air into the casing 1 and blowing it towards the outdoor heat exchanger 22. The air flowing through the outdoor heat exchanger 22 from inside the casing 1 is then discharged into the outdoor space through the air outlet duct 15, achieving outdoor air circulation.

[0061] As shown in Figures 2 and 4, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 can be located outside the third subspace 130. A receiving area 140 can be recessed on the upper part of the housing 1 corresponding to the outer wall of the third subspace 130. The air inlet pipe 14 and the air outlet pipe 15 can be arranged within the receiving area 140, allowing them to be positioned above the second subspace 120, and above the outdoor heat exchanger 22 and the outdoor fan assembly 3.

[0062] It should be noted that in some other embodiments, the air inlet duct 14 can also be used for exhaust, and the air outlet duct 15 can also be used for air intake. The air outlet duct 15 can introduce outdoor air into the housing 1 for heat exchange with the outdoor heat exchanger 22. The heat-exchanged air can then be transported to the outside through the air inlet duct 14 under the action of the outdoor fan assembly 3.

[0063] As shown in Figures 2 and 4, in some embodiments, the air inlet duct 14 and the air outlet duct 15 can be arranged side-by-side in the receiving area 140 on the outer wall of the housing 1. The lower end of the air inlet duct 14 can communicate with the air inlet end of the outdoor fan assembly 3. The lower end of the air outlet duct 15 can communicate with the second subspace 120 inside the housing 1. The upper ends of the air inlet duct 14 and the upper ends of the air outlet duct 15 can connect to the outdoor space. During the installation of the air conditioner, the air inlet duct 14 and the air outlet duct 15 can be extended and fixed to a wall or window, thereby connecting to the outdoor space.

[0064] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a first drip tray 5. The first drip tray 5 may be located within the housing 10. The first drip tray 5 may be positioned in the area between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 may be located above the first drip tray 5. The first drip tray 5 can be used to collect condensate flowing down the outer wall of the outdoor heat exchanger 22. When the air conditioner is in heating mode, the refrigerant can evaporate and absorb heat in the outdoor heat exchanger 22, lowering the surface temperature of the outdoor heat exchanger 22. Water vapor in the air condenses into water upon contact with the condensate, which then falls into the first drip tray 5 at the bottom of the outdoor heat exchanger 22. The condensate is collected in the first drip tray 5 or discharged after being collected through the first drip tray 5. This prevents condensate from dripping onto the ground, thus avoiding the risk of the air conditioner slipping or people slipping.

[0065] As shown in Figures 3 and 4, in some embodiments, the bottom port of the air outlet duct 15 can be arranged in the space above the first water receiving tray 5. When outdoor rainwater enters the housing 1 through the air outlet duct 15, it can be collected by the first water receiving tray 5, preventing the rainwater from flowing directly to other areas inside the housing 1 or seeping out of the housing 1 and flowing to the ground.

[0066] As shown in Figure 4, in some embodiments, a drain outlet 51 may be provided on the side wall of the first water receiving tray 5. A drain valve 52 may be provided at the drain outlet 51. The drain valve 52 can block the drain outlet 51. When the drain valve 52 opens the drain outlet 51, the drain outlet 51 can connect to the outside of the first water receiving tray 5, and the water in the first water receiving tray 5 can flow out of the outside of the first water receiving tray 5 through the drain outlet 51.

[0067] As shown in Figures 2 and 4, in some embodiments, the drain valve 52 can be located outside the housing 1, and the drain outlet 51 can be connected to the outside of the housing 1. When the drain valve 52 opens the drain outlet 51, the water in the first water receiving tray 5 can flow out to the outside of the housing 1 through the drain outlet 51.

[0068] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a second drip tray 6. The second drip tray 6 may be located inside the casing 1. The second drip tray 6 may be arranged in the area between the second subspace 120 and the third subspace 130. The indoor heat exchanger 23 may be located above the second drip tray 6. The second drip tray 6 can be used to collect condensate flowing down the outer wall of the indoor heat exchanger 23. When the air conditioner is cooling, the refrigerant can evaporate and absorb heat in the indoor heat exchanger 23, lowering the surface temperature of the indoor heat exchanger 23. Water vapor in the air condenses into water upon contact with the condensate, which then falls into the second drip tray 6 at the bottom of the indoor heat exchanger 23. The condensate is collected in the second drip tray 6 or discharged after being collected through the second drip tray 6. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and posing a risk of slipping and falling.

[0069] As shown in Figures 3 and 4, in some embodiments, the indoor fan assembly 4 can be positioned above the second water collection tray 6. The indoor fan assembly 4 can be positioned on one side of the indoor heat exchanger 23 laterally. The second water collection tray 6 can provide installation space for the indoor fan assembly 4, allowing the indoor fan assembly 4 and the indoor heat exchanger 23 to be arranged laterally adjacent to each other. This enables the indoor air introduced by the indoor fan assembly 4 to exchange heat with the indoor heat exchanger 23 nearby, which is beneficial to improving the heat exchange efficiency of the indoor heat exchanger 23.

[0070] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a housing 1, which includes a main housing 11 and a chassis 12, forming an internal receiving space 10. The air conditioner may include a refrigerant circulation loop disposed within the receiving space and including a compressor 21, a condenser, and an evaporator connected end-to-end. One of the condenser and evaporator is an outdoor heat exchanger 22, and the other is an indoor heat exchanger 23. The air conditioner may include an outdoor fan assembly 3, disposed on one side of the outdoor heat exchanger 22 to drive outdoor air to flow through the outdoor heat exchanger 22 for heat exchange. The air conditioner may include an indoor fan assembly 4, disposed on one side of the indoor heat exchanger 23 to drive indoor air to flow through the indoor heat exchanger 23 for heat exchange. The air conditioner may include a first drip tray 5, with the outdoor heat exchanger 22 disposed above the first drip tray 5. The air conditioner may include a second drip tray 6, with the indoor heat exchanger 23 disposed above the second drip tray 6. The second water collection tray 6 is positioned above the outdoor heat exchanger 22. The air conditioner may include an air inlet duct 14, which delivers outdoor air to the outdoor heat exchanger 22 for heat exchange. The air conditioner may also include an air outlet duct 15, which delivers the heat-exchanged air to the outside under the action of the outdoor fan assembly 3. The air inlet duct 14 and the air outlet duct 15 are positioned above the outdoor heat exchanger 22 and are horizontally spaced from the indoor fan assembly 4. The compressor 21 is positioned at the bottom of the casing 1, and the second water collection tray 6 is positioned above the compressor 21.

[0071] As shown in Figures 3 and 4, in some embodiments, the air conditioner may include a support member 7. The support member 7 may be disposed within the main housing 11. The support member 7 may be disposed within the receiving space 10. The support member 7 can be used to support the internal structure of the air conditioner. For example, the support member 7 can be used to support the outdoor heat exchanger 22, the outdoor fan assembly 3, the first drip tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the second drip tray 6, etc., thereby increasing the structural strength and stability of the air conditioner's internal structure.

[0072] As shown in Figures 3 and 4, in some embodiments, the lower part of the support member 7 can be located within the first subspace 110, and the bottom end of the support member 7 can be fixed to the chassis 12. The upper part of the support member 7 can be located within the second subspace 120, and the top end of the support member 7 can be supported at the bottom of the second water receiving tray 6, facilitating the installation of the indoor heat exchanger 23 and the indoor fan assembly 4 on the second water receiving tray 6. This allows the indoor heat exchanger 23 and the indoor fan assembly 4 to be supported on the top end of the support member 7 via the second water receiving tray 6, thereby improving the structural stability of the indoor heat exchanger 23 and the indoor fan assembly 4 within the third subspace 130.

[0073] As shown in Figures 3 and 4, in some embodiments, the first water receiving tray 5 can be supported and fixed on the upper part of the support member 7, facilitating the installation of the outdoor heat exchanger 22 on the first water receiving tray 5 and its support and fixation on the support member 7 via the first water receiving tray 5. The outdoor fan assembly 3 can be located on the upper part of the support member 7. In this way, the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 within the second subspace 120 can be improved.

[0074] It should be noted that in some other embodiments, the support member 7 can also be used to support any one or more of the outdoor heat exchanger 22, outdoor fan assembly 3, first water receiving tray 5, indoor heat exchanger 23, indoor fan assembly 4, and second water receiving tray 6. For example, the support member 7 can also be used to support the outdoor heat exchanger 22 and / or the indoor heat exchanger 23 alone.

[0075] As shown in Figure 4, in some embodiments, the outdoor fan assembly 3 may include an outdoor duct housing 30. An outdoor duct may be formed inside the outdoor duct housing 30. The air inlet of the outdoor duct housing 30 may connect to the outside, and the air outlet of the outdoor duct housing 30 may face the outdoor heat exchanger 22. Specifically, the air inlet of the outdoor duct housing 30 may connect to an air inlet pipe 14, and through the air inlet pipe 14, connect to the outdoor space. The air outlet of the outdoor duct housing 30 may be arranged facing the outdoor heat exchanger 22. Thus, the duct inside the outdoor duct housing 30 can draw air from the outdoor space through the air inlet pipe 14, introduce outdoor air into the housing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22.

[0076] As shown in Figure 4, in some embodiments, the outdoor duct housing 30 may include a volute member 31. The volute member 31 may be fixed to the support member 7. The air duct within the outdoor duct housing 30 may be formed within the volute member 31.

[0077] It should be noted that in some other embodiments, the outdoor duct housing 30 may not use the volute 31, that is, it may not use the volute structure, and the outdoor duct housing 30 may use duct housings of other shapes.

[0078] As shown in Figure 4, in some embodiments, a volute portion 71 can be formed on the upper part of the support member 7. A volute member 31 can be fixed to the volute portion 71, thereby fixing the volute member 31 to the support member 7. The volute member 31 and the volute portion 71 can be joined to form a volute structure, within which an outdoor air duct can be formed. That is, the volute member 31 and the volute portion 71 can be joined to form a complete outdoor air duct housing 30. This volute structure has an air inlet end and an air outlet end. The air inlet end of the volute structure connects to the air inlet pipe 14, thereby connecting to the outdoor space. The air outlet end of the volute structure connects to the second subspace 120 and is arranged towards the outdoor heat exchanger 22.

[0079] It should be noted that in some other embodiments, the outdoor duct housing 30 can also be formed by joining two opposing volute components 31 together. The joined outdoor duct housing 30 can also be detachably fixed to the support member 7. Alternatively, the outdoor duct housing 30 can also be formed by a single complete volute component 31.

[0080] As shown in Figure 4, in some embodiments, the outdoor fan assembly 3 may include an outdoor impeller (not shown in the figure). The outdoor impeller can be rotatably disposed within the outdoor duct housing 30, that is, the outdoor impeller can be rotatably disposed within the outdoor duct. The outdoor impeller can be rotatably disposed inside the volute component 31. When the outdoor impeller rotates, wind power can be generated inside the volute structure, allowing air from the outdoor space to enter the volute structure through the air inlet pipe 14, that is, to enter the outdoor duct.

[0081] As shown in Figure 4, in some embodiments, the outdoor fan assembly 3 may include an outdoor motor 32. The outdoor motor 32 may be mounted on the volute 31. The outdoor motor 32 may be fixed to the outside of the volute 31, so that the output shaft of the outdoor motor 32 extends into the inside of the volute 31 and is connected to the outdoor impeller via a drive. In this way, the outdoor motor 32 can drive the outdoor impeller to rotate inside the outdoor duct housing 30, thereby drawing air from the outdoor space into the outdoor duct housing 30 through the air inlet pipe 14 and blowing it into the second sub-space 120 to contact and exchange heat with the outdoor heat exchanger 22. The air after heat exchange can flow to the outside through the air outlet pipe 15. This solution integrates part of the outdoor duct housing 30 of the outdoor fan assembly 3 onto the support member 7, which can greatly improve the structural strength and structural stability of the outdoor fan assembly 3 and effectively ensure the stable operation of the outdoor fan assembly 3.

[0082] As shown in Figures 3 and 4, in some embodiments, a fixing rod 114 may be provided inside the housing 1. The fixing rod 114 may be located inside the main housing 11.

The second end of the air inlet pipe 14 can be the top end of the air inlet pipe 14, that is, the top end of the air inlet pipe 14 can be used to connect to the outdoor space.

[0090] It should be noted that in some other embodiments, the air inlet pipe 14 can also be arranged horizontally, and the first end and the second end of the air inlet pipe 14 can also be the two ends of the air inlet pipe 14 in the horizontal direction.

[0091] As shown in Figures 4 and 5, in some embodiments, the first mounting port 161 can be arranged above the outdoor air duct housing 30, thereby arranging the bottom end of the air inlet pipe 14 above the outdoor air duct housing 30, so that the bottom end of the air inlet pipe 14 is connected to the air inlet end of the outdoor air duct housing 30.

[0094] It should be noted that in some other embodiments, the air outlet duct 15 can also be arranged horizontally, and the first end and the second end of the air outlet duct 15 can also be the two horizontal ends of the air outlet duct 15.

[0095] As shown in Figures 4 and 5, in some embodiments, the second mounting port 162 can communicate with the second subspace 120. The second mounting port 162 can be arranged above the first water receiving tray 5, thereby causing the bottom end of the air outlet duct 15 to be arranged above the first water receiving tray 5.

[0096] As shown in Figures 5 and 6, in some embodiments, the first mounting port 161 and the second mounting port 162 can be arranged adjacent to each other on the mounting base 16 so that the air inlet pipe 14 and the air outlet pipe 15 are arranged adjacent to each other on the mounting base 16, which helps to reduce the size of the device.

[0097] As shown in Figures 7 and 8, in some embodiments, the air conditioner may include a mounting base 17. The mounting base 17 may be located outside the housing 1. The mounting base 17 may be connected to the air inlet pipe 14 and the air outlet pipe 15 respectively. The mounting base 17 is used to install on a wall or window, thereby fixing one end of the air inlet pipe 14 and the air outlet pipe 15 to the wall or window respectively, so that one end of the air inlet pipe 14 and the air outlet pipe 15 are respectively connected to the outside.

[0098] It should be noted that when the mounting bracket 17 is fixed to the wall or window, the installation angle and position of the mounting bracket 17 need to be adjusted, which will cause the ends of the air inlet pipe 14 and the air outlet pipe 15 to rotate or move.

[0099] As shown in Figures 7 and 8, in some embodiments, the second end of the air inlet pipe 14 can be fixedly connected to the mounting base 17.

[0107] As shown in Figures 7, 9, and 10, in some embodiments, a second connecting rib 1721 may be provided on the inner sidewall of the second fixing sleeve 172. The second connecting rib 1721 may have a sheet-like structure. The air outlet duct 15 may be constructed as a corrugated pipe. When the end of the air outlet duct 15 is located inside the second fixing sleeve 172, the second connecting rib 1721 may be inserted into the recess between adjacent corrugations of the air outlet duct 15, so that the end of the air outlet duct 15 is inserted and fixed inside the second fixing sleeve 172.

[0108] As shown in Figures 7, 9, and 10, in some embodiments, the fixing base 17 may be provided with a first grille portion 173. The first grille portion 173 may be arranged correspondingly to the first fixing sleeve 171. The first grille portion 173 may be located on the side of the first fixing sleeve 171 away from the air inlet pipe 14. When the second end of the air inlet pipe 14 is fixed inside the first fixing sleeve 171, the first grille portion 173 may block the second port of the air inlet pipe 14. In this way, the second port of the air inlet pipe 14 can be connected to the outside through the first grille portion 173, while the first grille portion 173 can prevent foreign objects from entering the air inlet pipe 14.

[0109] As shown in Figures 7, 9, and 10, in some embodiments, the fixing base 17 may be provided with a second grille portion 174. The second grille portion 174 may be arranged correspondingly to the second fixing sleeve 172. The second grille portion 174 may be located on the side of the second fixing sleeve 172 away from the air outlet duct 15. When the second end of the air outlet duct 15 is fixed inside the second fixing sleeve 172, the second grille portion 174 may cover the second port of the air outlet duct 15. In this way, the second port of the air outlet duct 15 can be connected to the outside through the second grille portion 174, while the second grille portion 174 can prevent foreign objects from entering the air outlet duct 15.

[0110] As shown in Figures 7 and 8, in some embodiments, the first end of the air inlet pipe 14 may be fixedly provided with a first connector 141. The first connector 141 is rotatably connected to the first mounting port 161. Thus, the end of the air inlet pipe 14 is provided with the first connector 141, which is a rotatable connection structure, so that the first end of the air inlet pipe 14 can be rotatably connected to the first mounting port 161, that is, the first end of the air inlet pipe 14 can rotate relative to the first mounting port 161, realizing the rotatable connection function of the first end of the air inlet pipe 14 relative to the first mounting port 161.

[0111] As shown in Figures 7 and 8, in some embodiments, the first end of the air outlet duct 15 may be fixedly provided with a second connector 151. The second connector 151 is rotatably connected to the second mounting port 162. Thus, the end of the air outlet duct 15 has a second connector 151, which is a rotatable connection structure, allowing the first end of the air outlet duct 15 to be rotatably connected to the second mounting port 162. That is, the first end of the air outlet duct 15 can rotate relative to the second mounting port 162, realizing the rotatable connection function of the first end of the air outlet duct 15 relative to the second mounting port 162.

[0112] When the second ends of the air inlet pipe 14 and the air outlet pipe 15 are respectively fixed on the mounting base 17, the first end of the air inlet pipe 14 can rotate through the first connector 141 at the first mounting port 161, and the first end of the air outlet pipe 15 can rotate through the second connector 151 at the second mounting port 162. Thus, when the mounting base 17 is installed on the cavity wall or window, the air inlet pipe 14 and the air outlet pipe 15 can maintain a reliable connection with the mounting base 17. As the mounting base 17 adjusts its installation position and angle, it can respectively drive the air inlet pipe 14 and the air outlet pipe 15 to rotate. The first end of the air inlet pipe 14 can rotate accordingly at the first mounting port 161, and the first end of the air outlet pipe 15 can rotate accordingly at the second mounting port 162, facilitating the installation of the mounting base 17 and simplifying its installation operation. Regardless of whether the mounting base 17 is installed horizontally or vertically, there is no need to disassemble the air inlet pipe 14 and the air outlet pipe 15. After the mounting base 17 is installed, the air inlet pipe 14 and the air outlet pipe 15 do not need to be installed separately. They can be installed in one go, and the installation angle is adjustable. No secondary adjustments are required, which greatly improves the installation efficiency and enhances the user's installation experience.

[0113] As shown in Figures 6, 12, and 13, in some embodiments, a first limiting rib 1611 may be provided on the inner peripheral wall of the first mounting port 161. The first limiting rib 1611 may have a ring-shaped structure. The first limiting rib 1611 may be arranged circumferentially around the inner peripheral wall of the first mounting port 161. The first connector 141 may be provided with a first buckle 1411 facing the first mounting port 161. The first buckle 1411 may extend into the first mounting port 161 and be rotatably engaged with the side of the first limiting rib 1611 away from the air inlet pipe 14. With the first limiting ribs 1611 evenly distributed circumferentially on the inner peripheral wall of the first mounting port 161, when the air inlet pipe 14 drives the first connector 141 to rotate within the first mounting port 161, the first buckle 1411 can rotate circumferentially along the first limiting rib 1611 within the first mounting port 161. At this time, the first latch 1411 can remain engaged with the side of the first limiting rib 1611 away from the air inlet pipe 14, thereby keeping the first connector 141 rotatably connected to the first mounting port 161 and preventing the first connector 141 from detaching from the first mounting port 161. In this way, a rotatable connection between the first connector 141 and the first mounting port 161 can be achieved, while effectively preventing the first connector 141 from accidentally detaching from the first mounting port 161, thereby ensuring the connection stability and reliability of the air inlet pipe 14.

[0114] As shown in Figures 12, 13, and 14, in some embodiments, the first connector 141 is provided with a first extension wall 1412 facing the first mounting port 161. The first extension wall 1412 may be annular. The first extension wall 1412 extends into the first mounting port 161 and is arranged circumferentially around the inner peripheral wall of the first mounting port 161. In this way, by uniformly distributing the first extension wall 1412 circumferentially on the inner peripheral wall of the first mounting port 161, the connection reliability between the first connector 141 and the first mounting port 161 of the mounting base 16 can be improved.

[0115] As shown in Figures 12, 13, and 14, in some embodiments, the first latch 1411 may be disposed on the inner wall of the first extension wall 1412 and extend from the inner wall of the first extension wall 1412 toward the first mounting port 161. When the first latch 1411 is engaged with the side of the first limiting rib 1611 away from the air inlet pipe 14, the first extension wall 1412 may abut against the side of the first limiting rib 1611 near the air inlet pipe 14. Thus, by cooperating with the first extension wall 1412 and the first latch 1411, respectively engaging with the opposite sides of the first limiting rib 1611, the connection reliability between the first connector 141 and the first mounting port 161 of the mounting base 16 can be improved. When the first connector 141 rotates relative to the first mounting port 161, the first extension wall 1412 can rotatably abut against the side of the first limiting rib 1611 near the air inlet pipe 14, and the first buckle 1411 can rotatably engage with the side of the first limiting rib 1611 away from the air inlet pipe 14, thereby maintaining the rotatable connection between the first connector 141 and the first mounting port 161, and ensuring the connection stability and reliability of the air inlet pipe 14.

[0116] As shown in Figures 12, 13, and 14, in some embodiments, the first extension wall 1412 may be located at the bottom of the first connector 141. The first latch 1411 may extend downward from the inner wall of the first extension wall 1412.

[0117] As shown in Figures 12, 13, and 14, in some embodiments, multiple first buckles 1411 may be provided. Multiple first buckles 1411 may be provided on the first connector 141. The multiple first buckles 1411 may be arranged circumferentially at intervals on the inner wall of the first extension wall 1412. The multiple first buckles 1411 may respectively engage with different areas of the first limiting rib 1611, thereby improving the connection stability and reliability between the first connector 141 and the first mounting port 161 of the mounting base 16.

[0118] As shown in Figures 13 and 14, in some embodiments, the first extension wall 1412 is bent towards the center of the first mounting port 161 to form a first bent portion 1413. The first bent portion 1413 can be located on the side of the first limiting rib 1611 near the center of the first mounting port 161. A corresponding groove structure can be formed on the outer side of the first bent portion 1413. The first buckle 1411 can extend from the first bent portion 1413 towards the first mounting port 161. Thus, through the structural arrangement of the first bent portion 1413, the first buckle 1411 can be arranged on the side of the first limiting rib 1611 near the center of the first mounting port 161, making it convenient for the first buckle 1411 to pass over the first limiting rib 1611 and then engage with the side of the first limiting rib 1611 away from the air inlet pipe 14.

[0119] As shown in Figures 13 and 14, in some embodiments, the first buckle 1411 may be located at the bottom of the first bend 1413. The first buckle 1411 may extend downward from the bottom of the first bend 1413.

[0120] As shown in Figures 6, 12, and 13, in some embodiments, a second limiting rib 1621 may be provided on the inner peripheral wall of the second mounting port 162. The second limiting rib 1621 may have a ring-shaped structure. The second limiting rib 1621 may be arranged circumferentially around the inner peripheral wall of the second mounting port 162. The second connector 151 may be provided with a second buckle 1511 facing the second mounting port 162. The second buckle 1511 may extend into the second mounting port 162 and be rotatably engaged with the side of the second limiting rib 1621 away from the air outlet pipe 15. With the second limiting ribs 1621 evenly distributed circumferentially on the inner peripheral wall of the second mounting port 162, when the air outlet pipe 15 drives the second connector 151 to rotate within the second mounting port 162, the second buckle 1511 can rotate circumferentially along the second limiting rib 1621 within the second mounting port 162. At this time, the second latch 1511 can remain engaged with the side of the second limiting rib 1621 away from the air outlet duct 15, thereby keeping the second connector 151 rotatably connected to the second mounting port 162 and preventing the second connector 151 from detaching from the second mounting port 162. In this way, a rotatable connection between the second connector 151 and the second mounting port 162 can be achieved, while effectively preventing the second connector 151 from accidentally detaching from the second mounting port 162, thus ensuring the connection stability and reliability of the air outlet duct 15.

[0121] As shown in Figures 12, 13, and 14, in some embodiments, the second connector 151 has a second extension wall 1512 facing the second mounting port 162. The second extension wall 1512 may be annular. The second extension wall 1512 extends into the second mounting port 162 and is arranged circumferentially around the inner peripheral wall of the second mounting port 162. In this way, by uniformly distributing the second extension wall 1512 circumferentially on the inner peripheral wall of the second mounting port 162, the connection reliability between the second connector 151 and the second mounting port 162 of the mounting base 16 can be improved.

[0122] As shown in Figures 12, 13, and 14, in some embodiments, the second latch 1511 may be disposed on the inner wall of the second extension wall 1512 and extend from the inner wall of the second extension wall 1512 toward the second mounting port 162. When the second latch 1511 is engaged with the side of the second limiting rib 1621 away from the air outlet duct 15, the second extension wall 1512 may abut against the side of the second limiting rib 1621 near the air outlet duct 15. Thus, by cooperating with the second extension wall 1512 and the second latch 1511, respectively engaging with opposite sides of the second limiting rib 1621, the connection reliability between the second connector 151 and the second mounting port 162 of the mounting base 16 can be improved. When the second connector 151 rotates relative to the second mounting port 162, the second extension wall 1512 can rotatably abut against the side of the second limiting rib 1621 near the air outlet 15, and the second buckle 1511 can rotatably engage with the side of the second limiting rib 1621 away from the air outlet 15, thereby maintaining the rotatable connection between the second connector 151 and the second mounting port 162, and ensuring the connection stability and reliability of the air outlet 15.

[0123] As shown in Figures 12, 13, and 14, in some embodiments, the second extension wall 1512 may be located at the bottom of the second connector 151. The second snap fastener 1511 may extend downward from the inner wall of the second extension wall 1512.

[0124] As shown in Figures 12, 13, and 14, in some embodiments, multiple second latches 1511 may be provided. Multiple second latches 1511 may be provided on the second connector 151. The multiple second latches 1511 may be arranged circumferentially at intervals on the inner wall of the second extension wall 1512. The multiple second latches 1511 may respectively engage with different areas of the second limiting rib 1621, thereby improving the connection stability and reliability between the second connector 151 and the second mounting port 162 of the mounting base 16.

[0125] As shown in Figures 13 and 14, in some embodiments, the second extension wall 1512 is bent towards the center of the second mounting port 162 to form a second bent portion 1513. The second bent portion 1513 can be located on the side of the second limiting rib 1621 near the center of the second mounting port 162. A corresponding groove structure can be formed on the outer side of the second bent portion 1513. The second buckle 1511 can extend from the second bent portion 1513 towards the second mounting port 162. Thus, through the structural arrangement of the second bent portion 1513, the second buckle 1511 can be arranged on the side of the second limiting rib 1621 near the center of the second mounting port 162, making it convenient for the second buckle 1511 to cross the second limiting rib 1621 and then engage with the side of the second limiting rib 1621 away from the air outlet duct 15.

[0126] As shown in Figures 13 and 14, in some embodiments, the second buckle 1511 may be located at the bottom of the second bend 1513. The second buckle 1511 may extend downward from the bottom of the second bend 1513.

[0127] As shown in Figures 8 and 13, in some embodiments, the inner sidewall of the first connector 141 may be provided with a sheet-like first positioning rib 1414. The air inlet pipe 14 may be constructed as a corrugated pipe. The first positioning rib 1414 can be used to insert into the recess between adjacent corrugations of the air inlet pipe 14. Thus, when the first connector 141 is installed at the end of the air inlet pipe 14, the first positioning rib 1414 can be inserted into the recess between adjacent corrugations of the air inlet pipe 14, so that the first connector 141 is stably connected to the end of the air inlet pipe 14.

[0128] As shown in Figures 8 and 13, in some embodiments, the first connector 141 can be fixed to the end of the air inlet pipe 14 by means of a threaded connection, and the first positioning rib 1414 is inserted into the recess between adjacent corrugations of the air inlet pipe 14.

[0129] As shown in Figures 8 and 13, in some embodiments, the inner sidewall of the second connector 151 may be provided with a sheet-like second positioning rib 1514. The air outlet duct 15 may be constructed as a corrugated pipe. The second positioning rib 1514 can be used to insert into the recess between adjacent corrugations of the air outlet duct 15. Thus, when the second connector 151 is installed at the end of the air outlet duct 15, the second positioning rib 1514 can be inserted into the recess between adjacent corrugations of the air outlet duct 15, so that the second connector 151 is stably connected to the end of the air outlet duct 15.

[0130] As shown in Figures 8 and 13, in some embodiments, the second connector 151 can be fixed to the end of the air outlet pipe 15 by means of a threaded connection, and the second positioning rib 1514 is inserted into the recess between adjacent corrugations of the air outlet pipe 15.

[0131] As shown in Figures 7, 15, and 16, in some embodiments, the air conditioner may include a duct fastener 18. The duct fastener 18 can be used to fix the air inlet duct 14 and the air outlet duct 15 relative to each other, so as to solve the problem of fixing the air inlet duct 14 and the air outlet duct 15 and prevent the air inlet duct 14 and the air outlet duct 15 from getting tangled together.

[0132] As shown in Figures 7, 15, and 16, in some embodiments, the duct fixing member 18 may include a fixing part 181. The fixing part 181 may be disposed between the air inlet duct 14 and the air outlet duct 15. The fixing part 181 may be clamped in the area between the air inlet duct 14 and the air outlet duct 15. The air inlet duct 14 and the air outlet duct 15 are respectively fixed on opposite sides of the fixing part 181.

[0133] As shown in Figures 7, 15, and 16, in some embodiments, the duct fixing member 18 may include a first fixing band 182. The first fixing band 182 may be elongated. A first end of the first fixing band 182 may be fixedly connected to one end of the fixing part 181. The first fixing band 182 may be wrapped around the outer periphery of the air inlet duct 14. A second end of the first fixing band 182 may be engaged with the other end of the fixing part 181. In this way, the first fixing band 182 and the fixing part 181 can be combined to form a first fixing ring 180a, and the first fixing ring 180a is fitted onto the outer periphery of the air inlet duct 14, fixing the air inlet duct 14 within the first fixing ring 180a, thus clamping the air inlet duct 14 in the area between the first fixing band 182 and the fixing part 181. In this way, the fixing problem of the air inlet duct 14 can be solved by the cooperation of the first fixing band 182 and the fixing part 181, thereby improving the structural stability of the air inlet duct 14.

[0134] It should be noted that the first end of the first fixing band 182 is the fixed end, which is fixedly connected to the fixing part 181 as a whole. Before fixing the air inlet pipe 14, the second end of the first fixing band 182 is the free end. When fixing the air inlet pipe 14, the second end of the first fixing band 182 is snapped into place with the other end of the fixing part 181, thereby fixing the second end of the first fixing band 182 to the fixing part 181, thus forming the first fixing ring 180a.

[0135] As shown in Figures 7, 15, and 16, in some embodiments, the duct fixing member 18 may include a second fixing band 183. The second fixing band 183 may be elongated. A first end of the second fixing band 183 may be fixedly connected to one end of the fixing part 181. The second fixing band 183 may be wrapped around the outer periphery of the air outlet duct 15. A second end of the second fixing band 183 may be engaged with the other end of the fixing part 181. In this way, the second fixing band 183 and the fixing part 181 can be combined to form a second fixing ring 180b, which is then fitted onto the outer periphery of the air outlet duct 15, fixing the air outlet duct 15 within the second fixing ring 180b, thus holding the air outlet duct 15 within the area between the second fixing band 183 and the fixing part 181. Therefore, through the cooperation of the second fixing band 183 and the fixing part 181, the problem of fixing the air outlet duct 15 can be solved, thereby improving the structural stability of the air outlet duct 15. In addition, the fixing part 181 cooperates with the first fixing strap 182 and the second fixing strap 183 to fix the air inlet pipe 14 and the air outlet pipe 15 on opposite sides of the fixing part 181, thereby solving the problem of relative fixation of the air inlet pipe 14 and the air outlet pipe 15 and preventing the air inlet pipe 14 and the air outlet pipe 15 from getting tangled together during installation or movement.

[0136] It should be noted that the first end of the second fixing band 183 is the fixed end, which is fixedly connected to the fixing part 181 as a whole. Before fixing the air outlet duct 15, the second end of the second fixing band 183 is the free end. When fixing the air outlet duct 15, the second end of the second fixing band 183 is snapped into place with the other end of the fixing part 181, thereby fixing the second end of the second fixing band 183 to the fixing part 181, and thus forming the second fixing ring 180b.

[0137] As shown in Figures 7, 17, and 18, in some embodiments, a first bending portion 184 may be provided on the first fixing band 182. The first bending portion 184 may protrude towards the outer periphery of the first fixing band 182. The first bending portion 184 has an elastic deformation function. The first bending portion 184 can elastically deform in the circumferential direction of the first fixing ring 180a to change the circumference of the first fixing ring 180a. In this way, when the first fixing band 182 is wrapped around the outer periphery of the air inlet duct 14, the diameter of the first fixing ring 180a formed by the first fixing band 182 and the fixing portion 181 can be automatically adjusted to adapt to air inlet ducts 14 with different diameters. For example, if the diameter of the air inlet duct 14 differs due to manufacturing errors or different models, it can be fixed by the first fixing band 182 of the duct fixing member 18. Specifically, when the second end of the first fixing strap 182 is engaged with one end of the fixing part 181, the second end of the first fixing strap 182 can apply tension to the first bending part 184, so that the first bending part 184 can elastically deform in the circumferential direction of the first fixing ring 180a, change the circumference of the first fixing ring 180a, automatically adjust the diameter of the first fixing ring 180a, and stably clamp the first fixing strap 182 and the fixing part 181 on the outer periphery of the air inlet pipe 14.

[0138] It should be noted that when the second end of the first fixing band 182 is separated from one end of the fixing part 181, the tension applied to the first bending part 184 disappears, and the first bending part 184 can deform and return to its original position.

[0139] As shown in Figures 7, 17, and 18, in some embodiments, a first opening area 1820 may be provided on the first fixing band 182. The first fixing band 182 may have a first opening end 1821 and a second opening end 1822 formed on opposite sides of the first opening area 1820. One end of the first bent portion 184 may be bent and connected to the first opening end 1821. The other end of the first bent portion 184 may be bent and connected to the second opening end 1822. The first opening area 1820 may be formed in the region between the first opening end 1821, the second opening end 1822, and the first bent portion 184. When the second end of the first fixing band 182 is engaged with one end of the fixing portion 181, the second end of the first fixing band 182 can apply tension to the first bent portion 184, causing the first bent portion 184 to elastically deform in the circumferential direction of the first fixing ring 180a, thereby changing the distance between the first opening end 1821 and the second opening end 1822, and thus adjusting and changing the circumference of the first fixing ring 180a.

[0140] As shown in Figures 17 and 18, in some embodiments, the first bent portion 184 may include a first extension 1841. The first extension 1841 may be bent and extended from the first open end 1821 toward the outside of the first retaining ring 180a. The inner end of the first extension 1841 may be bent and connected to the first open end 1821. The first extension 1841 may be located on one side of the first open area 1820.

[0141] As shown in Figures 17 and 18, in some embodiments, the first bent portion 184 may include a second extension 1842. The second extension 1842 may be bent and extended from the second open end 1822 toward the outside of the first retaining ring 180a. The inner end of the second extension 1842 may be bent and connected to the second open end 1822. The second extension 1842 may be located on the other side of the first opening area 1820. That is, the first extension 1841 and the second extension 1842 may be located on opposite sides of the first opening area 1820.

[0142] As shown in Figures 17 and 18, in some embodiments, the first bend 184 may include a first connecting segment 1843. The first connecting segment 1843 may connect between the first extension segment 1841 and the second extension segment 1842. One end of the first connecting segment 1843 may be bent to connect with the end of the first extension segment 1841 away from the first opening end 1821, i.e., one end of the first connecting segment 1843 may be bent to connect with the outer end of the first extension segment 1841. The other end of the first connecting segment 1843 may be bent to connect with the end of the second extension segment 1842 away from the second opening end 1822, i.e., the other end of the first connecting segment 1843 may be bent to connect with the outer end of the second extension segment 1842. A first opening region 1820 may be formed in the region between the first connecting segment 1843, the first extension segment 1841, and the second extension segment 1842.

[0143] Specifically, when the second end of the first fixing band 182 is engaged with one end of the fixing part 181, the second end of the first fixing band 182 can apply tension to the first bending part 184. The first connecting segment 1843, the first extension segment 1841 and the second extension segment 1842 can elastically deform along the circumferential direction of the first fixing ring 180a, changing the included angle between the first connecting segment 1843 and the first extension segment 1841 and the included angle between the first connecting segment 1843 and the second extension segment 1842, thereby changing the distance between the first opening end 1821 and the second opening end 1822, and thus changing the circumference of the first fixing ring 180a.

[0144] As shown in Figures 7, 17, and 18, in some embodiments, a second curved portion 185 may be provided on the second fixing band 183. The second curved portion 185 may protrude towards the outer periphery of the second fixing band 183. The second curved portion 185 has an elastic deformation function. The second curved portion 185 can elastically deform in the circumferential direction of the second fixing ring 180b to change the circumference of the second fixing ring 180b. Thus, when the second fixing band 183 is wrapped around the outer periphery of the air outlet duct 15, the diameter of the second fixing ring 180b formed by the second fixing band 183 and the fixing portion 181 can be automatically adjusted to adapt to air outlet ducts 15 with different diameters. For example, if the diameter of the air outlet duct 14 differs due to manufacturing errors, or if the diameter of the air outlet duct 15 differs due to different models, it can be fixed by the second fixing band 183 of the duct fixing member 18. Specifically, when the second end of the second fixing band 183 is engaged with one end of the fixing part 181, the second end of the second fixing band 183 can apply tension to the second bending part 185, so that the second bending part 185 can elastically deform in the circumferential direction of the second fixing ring 180b, change the circumference of the second fixing ring 180b, automatically adjust the diameter of the second fixing ring 180b, and stably clamp the second fixing band 183 and the fixing part 181 on the outer periphery of the air outlet pipe 15.

[0145] It should be noted that when the second end of the second fixing band 183 is separated from one end of the fixing part 181, the tension applied to the second bending part 185 disappears, and the first bending part 184 can deform and return to its original position.

[0146] As shown in Figures 7, 17, and 18, in some embodiments, the second fixing band 183 may have a second opening region 1830. The second fixing band 183 may have a third opening end 1831 and a fourth opening end 1832 formed on opposite sides of the second opening region 1830, respectively. One end of the second bent portion 185 may be bent to connect with the third opening end 1831. The other end of the second bent portion 185 may be bent to connect with the fourth opening end 1832. The second opening region 1830 may be formed in the area between the third opening end 1831, the fourth opening end 1832, and the second bent portion 185. When the second end of the second fixing band 183 is engaged with one end of the fixing part 181, the second end of the second fixing band 183 can apply tension to the second curved part 185, so that the second curved part 185 can elastically deform in the circumferential direction of the second fixing ring 180b, thereby changing the distance between the third opening end 1831 and the fourth opening end 1832, and thus adjusting and changing the circumference of the second fixing ring 180b.

[0147] As shown in Figures 17 and 18, in some embodiments, the second curved portion 185 may include a third extension 1851. The third extension 1851 may be bent and extended from the third open end 1831 toward the outside of the second retaining ring 180b. The inner end of the third extension 1851 may be bent and connected to the third open end 1831. The third extension 1851 may be located on one side of the second opening area 1830.

[0148] As shown in Figures 17 and 18, in some embodiments, the second curved portion 185 may include a fourth extension 1852. The fourth extension 1852 may be bent and extended from the fourth open end 1832 toward the outside of the second retaining ring 180b. The inner end of the fourth extension 1852 may be bent and connected to the fourth open end 1832. The fourth extension 1852 may be located on the other side of the second opening area 1830. That is, the third extension 1851 and the fourth extension 1852 may be located on opposite sides of the second opening area 1830.

[0149] As shown in Figures 17 and 18, in some embodiments, the second bend 185 may include a second connecting segment 1853. The second connecting segment 1853 may connect between the third extension segment 1851 and the fourth extension segment 1852. One end of the second connecting segment 1853 may be bent to connect with the end of the third extension segment 1851 away from the third opening end 1831, i.e., one end of the second connecting segment 1853 may be bent to connect with the outer end of the third extension segment 1851. The other end of the second connecting segment 1853 may be bent to connect with the end of the fourth extension segment 1852 away from the fourth opening end 1832, i.e., the other end of the second connecting segment 1853 may be bent to connect with the outer end of the fourth extension segment 1852. A second opening region 1830 may be formed in the region between the second connecting segment 1853, the third extension segment 1851, and the fourth extension segment 1852.

[0150] Specifically, when the second end of the second fixing band 183 is engaged with one end of the fixing part 181, the second end of the second fixing band 183 can apply tension to the second curved part 185. The second connecting section 1853, the third extension section 1851 and the fourth extension section 1852 can elastically deform along the circumferential direction of the second fixing ring 180b, changing the included angle between the second connecting section 1853 and the third extension section 1851 and the included angle between the second connecting section 1853 and the fourth extension section 1852, thereby changing the distance between the third opening end 1831 and the fourth opening end 1832, and thus changing the circumference of the second fixing ring 180b.

[0151] As shown in Figures 15 and 16, in some embodiments, a first arc-shaped wall 1811 may be formed on the side of the fixing part 181 facing the air inlet pipe 14. The first arc-shaped wall 1811 can be formed with the first fixing band 182 to form a first fixing ring 180a. When the first fixing ring 180a is sleeved on the outer wall of the air inlet pipe 14, the inner sidewalls of the first arc-shaped wall 1811 and the first fixing band 182 can be tightly attached to the outer wall of the air inlet pipe 14, thereby improving the connection stability between the air inlet pipe 14 and the duct fixing member 18.

[0152] As shown in Figures 15 and 16, in some embodiments, a second arc-shaped wall 1812 may be formed on the side of the fixing part 181 facing the air outlet duct 15. The second arc-shaped wall 1812 can be formed with the second fixing band 183 to form a second fixing ring 180b. When the second fixing ring 180b is sleeved on the outer wall of the air outlet duct 15, the inner sidewalls of the second arc-shaped wall 1812 and the second fixing band 183 can respectively adhere tightly to the outer wall of the air outlet duct 15, improving the connection stability between the air outlet duct 15 and the duct fixing member 18.

[0153] As shown in Figures 15 and 17, in some embodiments, one end of the fixing part 181 may be provided with a first slot 1813. The second end of the first fixing band 182 may be provided with a first insertion part 1824. The first insertion part 1824 can be inserted into and engaged in the first slot 1813, thereby fixing the second end of the first fixing band 182 to the fixing part 181. In this way, the first insertion part 1824 and the first slot 1813 can cooperate to make the second end of the first fixing band 182 conveniently and quickly fixed to the end of the fixing part 181, thereby forming a first fixing ring 180a by the first fixing band 182 and the fixing part 181, which facilitates fixing the air inlet pipe 14 in the first fixing ring 180a.

[0154] It should be noted that in some other embodiments, the first slot 1813 may also be located at the second end of the first fixing band 182. In this case, the first insertion part 1824 may also be located at one end of the fixing part 181.

[0155] As shown in Figures 15 and 17, in some embodiments, one end of the fixing part 181 may be provided with a second slot 1814. The second end of the second fixing band 183 may be provided with a second insertion part 1834. The second insertion part 1834 can be inserted into and engaged in the second slot 1814, thereby fixing the second end of the second fixing band 183 to the fixing part 181. In this way, the second insertion part 1834 and the second slot 1814 can cooperate to make the second end of the second fixing band 183 conveniently and quickly fixed to the end of the fixing part 181, thereby forming a second fixing ring 180b by the second fixing band 183 and the fixing part 181, which facilitates fixing the air outlet duct 15 in the second fixing ring 180b.

[0156] It should be noted that in some other embodiments, the second slot 1814 may also be located at the second end of the second fixing band 183. In this case, the second insertion part 1834 may also be located at one end of the fixing part 181.

[0157] As shown in Figures 15 and 17, in some embodiments, the first slot 1813 and the second slot 1814 may be located at the same end of the fixing part 181. The first slot 1813 and the second slot 1814 may be arranged adjacent to each other on the same end face of the fixing part 181. In this way, it is convenient for the user to sequentially insert the second end of the first fixing strap 182 and the second end of the second fixing strap 183 into the same end of the fixing part 181, thereby improving the installation efficiency of the duct fixing component 18.

[0158] It should be noted that in some other embodiments, the first slot 1813 and the second slot 1814 may be respectively located at opposite ends of the fixing part 181.

[0159] As shown in Figures 7 and 15, in some embodiments, the inner side of the first fixing band 182 may be provided with a sheet-like first fixing rib 1823. The air inlet duct 14 may be constructed as a corrugated pipe. The first fixing rib 1823 can be used to insert into the recesses between adjacent corrugations of the air inlet duct 14. Thus, when the first fixing band 182 is wrapped around the outer periphery of the air inlet duct 14, the first fixing band 182 can be stably connected to a specific position on the outer wall of the air inlet duct 14 by inserting the first fixing rib 1823 into the recesses between adjacent corrugations of the air inlet duct 14.

[0160] As shown in Figures 7 and 15, in some embodiments, the inner side of the second fixing band 183 may be provided with a sheet-like second fixing rib 1833. The air outlet duct 15 may be constructed as a corrugated pipe. The second fixing rib 1833 can be used to insert into the recesses between adjacent corrugations of the air outlet duct 15. Thus, when the second fixing band 183 is wrapped around the outer periphery of the air outlet duct 15, the second fixing band 183 can be stably connected to a specific position on the outer wall of the air outlet duct by inserting the second fixing rib 1833 into the recesses between adjacent corrugations of the air outlet duct 15.

[0161] As shown in Figures 2, 15, and 16, in some embodiments, a first guide portion 1825 may be provided on the top of the first fixing band 182 near the indoor air inlet 111. The first guide portion 1825 may protrude upward from the top surface of the first fixing band 182. The outer wall of the first guide portion 1825 may be inclined upward toward the side near the air inlet duct 14. In this way, when the filter is installed or removed at the indoor air inlet 111, the outer wall of the first guide portion 1825 can provide guidance for the filter, preventing the first fixing band 1823 from obstructing the installation and removal of the filter.

[0162] As shown in Figures 2, 15, and 16, in some embodiments, a second guide portion 1826 may be provided at the bottom of the first fixing band 182 on the side near the indoor air inlet 111. The second guide portion 1826 may protrude downward from the bottom surface of the first fixing band 182. The outer wall of the second guide portion 1826 may be inclined downward toward the side near the air inlet duct 14. In this way, when the filter is installed or removed at the indoor air inlet 111, the outer wall of the second guide portion 1826 can provide guidance for the filter, preventing the first fixing band 182 from obstructing the installation and removal of the filter.

[0163] For example, the filter can be installed inside the indoor air inlet 111 from top to bottom and can be removed from the indoor air inlet 111 from bottom to top. In this way, the outer wall of the first guide portion 1825 can provide guidance for the installation of the filter, and the outer wall of the second guide portion 1826 can provide guidance for the removal of the filter.

[0164] As shown in Figures 2, 15, and 16, in some embodiments, a third guide portion 1835 may be provided at the top of the second fixing band 183 on the side near the indoor air inlet 111. The third guide portion 1835 may protrude upward from the top surface of the second fixing band 183. The outer wall of the third guide portion 1835 may be inclined upward toward the side near the air outlet duct 15. In this way, when the filter is installed or removed at the indoor air inlet 111, the outer wall of the third guide portion 1835 can provide guidance for the filter, preventing the second fixing band 183 from obstructing the installation and removal of the filter.

[0165] As shown in Figures 2, 15, and 16, in some embodiments, a fourth guide portion 1836 may be provided at the bottom of the second fixing band 183 on the side near the indoor air inlet 111. The fourth guide portion 1836 may protrude downward from the bottom surface of the second fixing band 183. The outer wall of the fourth guide portion 1836 may be inclined downward toward the side near the air outlet duct 15. In this way, when the filter is installed or removed at the indoor air inlet 111, the outer wall of the fourth guide portion 1836 can provide guidance for the filter, preventing the second fixing band 183 from obstructing the installation and removal of the filter.

[0166] For example, the filter can be installed inside the indoor air inlet 111 from top to bottom and can be removed from the indoor air inlet 111 from bottom to top. Thus, the outer wall of the third guide portion 1835 can provide guidance for the installation of the filter, and the outer wall of the fourth guide portion 1836 can provide guidance for the removal of the filter.

[0167] Those skilled in the art will understand that the scope of this disclosure is not limited to the specific embodiments described above, and that modifications and substitutions can be made to certain elements of the embodiments without departing from the spirit of this disclosure. The scope of this disclosure is limited by the appended claims.
