Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a fresh air module and an air conditioner. Background Technology

[0002] When a window air conditioner is running in cooling mode, it simultaneously lowers both the indoor air temperature and humidity. Prolonged use can lead to an overly dry indoor environment, affecting user comfort. To address this, some users use a separate humidifier while the air conditioner is on, but this method is inconvenient and takes up extra indoor space.

[0003] To address these issues, some existing technologies have attempted to integrate fresh air and humidification functions into window air conditioners. For example, some solutions achieve humidification by adding a fresh air module inside the air conditioner, along with components such as atomizers or ultrasonic vibrators. However, these solutions are typically complex in structure, expensive, and sometimes require additional components such as water pumps, often occupying limited internal space within the air conditioner.

[0004] Therefore, how to achieve both fresh air exchange and air humidification functions within the limited internal space of a window air conditioner, with a simple and reliable structure and low cost, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The main objective of this invention is to provide a fresh air module and an air conditioner to solve the above-mentioned technical problems.

[0006] In a first aspect, the present invention provides a fresh air module suitable for an air conditioner, the air conditioner including an evaporator and a drip tray disposed below the evaporator, the drip tray being used to collect condensate from the evaporator, the fresh air module comprising:

[0007] A support section, on which a fresh air inlet is provided, and a fresh air fan is provided at the fresh air inlet;

[0008] A humidification assembly, disposed on the support portion, comprises a sealing section, a humidification section, and a water absorption section connected in sequence; and

[0009] A drive mechanism, connected to the humidification component, is used to drive the humidification component to move so that the sealing section or the humidification section covers the fresh air inlet;

[0010] When the humidification section covers the fresh air inlet, the water absorption section can be immersed in or detached from the condensate in the water receiving tray. After being immersed in the condensate, the water absorption section can absorb the condensate and supply it to the humidification section.

[0011] The support section is vertically arranged, and the sealing section, the humidifying section, and the water-absorbing section are arranged sequentially from top to bottom along the support section; the driving mechanism is located on the upper part of the support section and is connected to the sealing section.

[0012] The sealing section is an airtight sheet structure; the humidifying section is a porous structure; and the water-absorbing section is a wicking structure.

[0013] The drive mechanism includes a reel connected to the sealing section and a drive motor for driving the reel to rotate.

[0014] A filter screen is also installed at the fresh air inlet.

[0015] In a second aspect, the present invention also provides an air conditioner, including an evaporator and a water collection tray disposed below the evaporator, and further including a fresh air module as described in the first aspect.

[0016] The system also includes a partition plate. The evaporator includes an evaporator body and an inlet / outlet pipe connected to the evaporator body. The fresh air module is mounted on the partition plate, and the fresh air fan of the fresh air module blows air towards the area where the inlet / outlet pipe is located.

[0017] The device also includes a centrifugal fan, which is disposed between the partition plate and the evaporator body. The fresh air module is disposed at one edge of the partition plate and located on one side of the centrifugal fan. An air outlet is provided on the other side of the centrifugal fan opposite to the fresh air module.

[0018] The system also includes a base, with a partition plate disposed on the base to divide the space above the base into an indoor section and an outdoor section; the evaporator and the centrifugal fan are both disposed in the indoor section and fixedly connected to the base; the fresh air inlet of the fresh air module passes through the partition plate to connect the indoor section and the outdoor section.

[0019] The water receiving tray includes a water receiving part, a water absorption part, and an overflow part connected in sequence. The water receiving part is located below the evaporator, the water absorption part is located below the fresh air module, and the overflow port of the overflow part is lower than the upper edge of the water absorption part.

[0020] Beneficial technical effects of the present invention:

[0021] This invention utilizes an integrated humidification component within an air conditioner, comprising a sealing section, a humidification section, and a water absorption section. A drive mechanism controls its position relative to the fresh air inlet, allowing the fresh air module to flexibly switch between three operating modes: fresh air off, pure fresh air, or fresh air humidification. In fresh air humidification mode, the water absorption section uses capillary action to collect naturally generated condensate from the drip tray during the cooling process and continuously supplies it to the humidification section, effectively humidifying the incoming fresh air as it passes through the humidification section. This structure eliminates the need for additional water pumps, atomizers, or water replenishment devices, simplifying the overall structure, reducing costs, and avoiding the need to occupy limited internal space.

[0022] In summary, the fresh air module of this invention integrates fresh air exchange and humidification functions in a simple and reliable manner within a limited space, which can effectively improve the indoor dryness caused by the cooling process and enhance the comfort of indoor air.

[0023] Furthermore, the support portion of this invention is vertically arranged, with the sealing section, humidification section, and water absorption section of the humidification component arranged sequentially from top to bottom. The drive mechanism is located at the top, employing a roller and drive motor to achieve the winding and unwinding of the component. This vertical arrangement fully utilizes the limited space inside the window air conditioner and, with the help of gravity from top to bottom, ensures smooth and reliable unfolding and retraction of the humidification component. The drive mechanism is positioned at the top, away from the water collection tray, further preventing moisture absorption and extending its service life. Unlike existing solutions that rely on water pumps or stationary capillaries, this invention achieves precise motion control with fewer components and lower cost by driving the flexible curtain-like component with a roller, significantly improving operational stability.

[0024] The air conditioner provided by this invention first blows fresh air into the evaporator inlet and outlet pipes (refrigerant pipes) where the temperature is lower, using this "natural cold source" to pre-cool the introduced hot outdoor air. The pre-cooled fresh air is then mixed with indoor return air and undergoes a second cooling process through the evaporator body. This multi-stage cooling process improves cooling efficiency compared to directly mixing hot fresh air into the main air duct, and makes the final delivered mixed air temperature more uniform and comfortable.

[0025] Furthermore, the air conditioner arranges the fresh air module to the side and at the edge. This layout avoids obstructing the main indoor air circulation duct, ensuring that the air conditioner's original high-efficiency airflow is not affected. The fresh air enters the main air duct from the side, mixes smoothly with the indoor return air, and is then uniformly delivered by a centrifugal fan, ensuring perfect compatibility between the fresh air function and the air conditioner's original cooling performance.

[0045] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0046] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0047] Please also refer to Figures 1-4 This invention provides a fresh air module suitable for installation in an air conditioner, particularly a window air conditioner. The air conditioner includes an evaporator 41 and a drip tray 50 disposed below the evaporator 41 to collect condensate from the evaporator 41. The fresh air module includes a support portion 11 with a fresh air inlet 12 and a fresh air fan 13 at the inlet 12; and a humidification assembly 20 disposed on the support portion 11, comprising a sealing section 21, a humidification section 22, and an absorption section connected in sequence. The water section 23; and the drive mechanism 30, which is connected to the humidification component 20, for driving the humidification component 20 to move so that the sealing section 21 or the humidification section 22 covers the fresh air inlet 12; wherein, when the humidification section 22 covers the fresh air inlet 12, the water absorption section 23 can be immersed in or detached from the condensate in the water receiving tray 50, and after the water absorption section 23 is immersed in the condensate, it can absorb the condensate to supply to the humidification section 22.

[0048] In this embodiment, during the cooling operation of the air conditioner, condensation will occur on the surface of the evaporator 41, dripping into the drip tray 50 and collecting. The fresh air module of this embodiment utilizes this condensation to humidify the fresh air. Specifically, the fresh air module of this embodiment includes a support 11, a humidification component 20, and a drive mechanism 30.

[0049] In a specific example, such as Figure 2 and Figure 3 As shown, the support 11 can be part of a partition 80 located inside the air conditioner, which separates the indoor and outdoor parts of the air conditioner. Directly mounting the humidification assembly 20 and the drive mechanism 30 on the partition 80 effectively utilizes the existing space inside the air conditioner.

[0050] The support 11 has a fresh air inlet 12, through which fresh outdoor air enters the air conditioner. In order to drive the flow of fresh air, a fresh air fan 13 is also provided at the fresh air inlet 12. When the fresh air fan 13 is working, it can draw outdoor air into the indoor part of the air conditioner.

[0051] like Figure 1 and Figure 4 As shown, the humidification component 20, in this embodiment, is an integrated flexible curtain structure. The humidification component 20 is disposed on the support portion 11 and is used to selectively cover the fresh air inlet 12. The humidification component 20 includes a sealing section 21, a humidification section 22, and a water-absorbing section 23 connected to the humidification section 22, arranged sequentially. Here, "arranged sequentially" can be understood as the three components being connected sequentially along their length to form a single unit.

[0052] The drive mechanism 30 is connected to the humidification component 20 and is used to drive the humidification component 20 to move along the support portion 11. Driven by the drive mechanism 30, the humidification component 20 can move up and down, thereby achieving selective coverage of the fresh air inlet 12 by its different functional sections. For example, the sealing section 21 can cover the fresh air inlet 12, or the humidification section 22 can cover the fresh air inlet 12.

[0053] The key to this embodiment lies in the utilization of condensate. Its working principle is as follows:

[0054] When fresh air needs to be turned on and humidification is performed simultaneously (i.e., fresh air humidification mode), the drive mechanism 30 drives the humidification component 20 to move, so that the humidification section 22 moves to a position that just covers the fresh air inlet 12. At this position, the water absorption section 23 connected to the humidification section 22 can be immersed in the condensate collected in the water receiving tray 50 below.

[0055] After the water absorption section 23 is immersed in condensate, it can absorb the condensate using its own capillary action or water absorption characteristics and continuously supply it to the connected humidification section 22, keeping the humidification section 22 moist. At this time, the fresh air fan 13 starts, and the outdoor fresh air is drawn in and carries away the moisture as it passes through the moist humidification section 22, thus forming moist fresh air that enters the room, achieving the function of simultaneous fresh air and humidification.

[0056] Furthermore, when humidification is not required or the humidification level needs adjustment, the drive mechanism 30 can also drive the humidification component 20 to move, causing the end of the water absorption section 23 to detach from the condensate surface in the water collection tray 50. At this time, the water absorption section 23 can no longer absorb condensate, and the humidification section 22 will gradually dry out, thus stopping the humidification of the fresh air.

[0057] With the above structure, the fresh air module of this embodiment uses the condensate water generated by the air conditioner itself as the humidification water source, without the need for additional water replenishment, and the structure is simple and compact; and by controlling the movement of the humidification component 20 through the drive mechanism 30, integrated control of the opening and closing of the fresh air inlet 12 and the humidification function is realized, which improves the user experience.

[0058] In one embodiment, the support portion 11 is vertically arranged, and the sealing section 21, the humidifying section 22 and the water-absorbing section 23 are arranged sequentially from top to bottom along the support portion 11; the driving mechanism 30 is disposed on the upper part of the support portion 11 and is connected to the sealing section 21.

[0059] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the support 11 is vertically arranged inside the air conditioner. This vertical arrangement is very suitable for layout in the compact space of window air conditioners, and can effectively utilize vertical space.

[0060] Correspondingly, the sealing section 21, humidifying section 22 and water-absorbing section 23 in the humidifying assembly 20 are also connected and arranged sequentially from top to bottom along the vertical direction of the support part 11.

[0061] Specifically, the sealing section 21 is located at the top of the humidification assembly 20, the humidification section 22 is connected below the sealing section 21, and the water absorption section 23 is connected below the humidification section 22 and located at the bottom of the entire humidification assembly 20.

[0062] To effectively drive the vertically arranged humidification component 20, the drive mechanism 30 is located at the top of the support portion 11. Furthermore, the power output end of the drive mechanism 30 is directly connected to the sealing section 21 located at the uppermost end of the humidification component 20.

[0063] This "top-driven, top-down" layout means that when the drive mechanism 30 is working, the entire humidification component 20 will be rolled up; when the drive mechanism 30 is working in the opposite direction, the entire humidification component 20 can be smoothly unfolded downwards under its own gravity.

[0064] This retracting and unfolding action allows for convenient and precise control over whether the humidifying section 22 in the middle covers the fresh air inlet 12 (turning on fresh air humidification) or the sealing section 21 at the top covers the fresh air inlet 12 (turning off fresh air). The control logic is clear, and the structure operates reliably. Furthermore, placing the drive mechanism 30 at the top helps to keep it away from the humid environment in the water collection tray 50 below, improving the operational stability and lifespan of the drive mechanism 30.

[0065] In one specific embodiment, to ensure the stability of the humidification component 20 during vertical movement along the support portion 11, guide structures may be provided on both sides of the support portion 11. For example, the guide structure may be a pair of parallel grooves extending in the vertical direction.

[0066] Accordingly, the two side edges of the humidification component 20 can directly engage with the corresponding side grooves and be slidably embedded in the grooves.

[0067] This design effectively constrains the movement trajectory of the humidification component 20, preventing it from swaying, tilting, or getting stuck during lifting and lowering, thus ensuring that it can accurately cover or clear the fresh air inlet 12. Furthermore, the chute also constrains the humidification component 20, preventing it from twisting on the surface of the support 11 and causing visible gaps between the humidification component 20 and the support 11.

[0068] In other embodiments, a magnetic strip may be embedded in the lower part of the sealing section 21, which is attached to the support part 11 (metal). During the up-and-down movement of the sealing section 21, it can be ensured that it always fits against the support part 11, thereby ensuring the airtightness of the fresh air inlet 12 in non-fresh air mode.

[0069] In one specific embodiment, the humidification component 20 is generally presented as a flexible, bendable curtain structure. This flexibility allows the humidification component 20 to be smoothly rolled upward by the top drive mechanism 30 to move its different functional sections (such as the humidification section) to the working position of the fresh air inlet 12.

[0070] Meanwhile, when the fresh air function needs to be turned off, this flexibility also allows the humidification component 20 to unfold downwards under the control of the drive mechanism 30. Its lower humidification section 22 and water absorption section 23 can fall smoothly and be stored in the water receiving tray 50, while its upper sealing section 21 can flatly cover the fresh air inlet 12 to achieve a reliable seal.

[0071] This design, through the simple action of rolling up and unfolding, completes the switching of working state and the storage of non-working parts, with a compact structure and reliable operation.

[0072] In one specific embodiment, the drive mechanism 30 and the sealing section 21 are connected in a fixed manner. Specifically, the drive mechanism 30 includes a rotatable power output component, and the upper edge of the sealing section 21 is fixed to the outer peripheral surface of the power output component. When the power output component rotates, it drives the sealing section 21, thereby rolling up or unfolding the entire humidification assembly 20 connected to it. To ensure the reliability of the connection, a reinforcing rod (not shown) can be embedded or fixed in the upper edge of the sealing section 21. This reinforcing rod is fixedly connected to the power output component to prevent the flexible sealing section 21 from undergoing uncontrollable deformation or tearing at the stress point.

[0073] In one embodiment, the sealing section 21 is an airtight sheet structure; the humidifying section 22 is a porous structure; and the water-absorbing section 23 is a wicking structure.

[0074] like Figure 4 As shown, in this embodiment, the sealing section 21 is an airtight sheet structure, which can be made of a flexible, airtight material. The main function of the sealing section 21 is that when the fresh air or humidification function is turned off, the drive mechanism 30 drives the humidification component 20 to descend (or unfold), so that the sealing section 21 can completely cover the fresh air inlet 12.

[0075] Due to its airtight nature, the sealing section 21 can effectively isolate indoor and outdoor air circulation, avoiding problems such as air leakage in non-fresh air mode, and ensuring the normal operation of the air conditioner when fresh air or humidification functions are not required. The "sheet-like" and flexible nature of the sealing section 21 also makes it easy to be rolled up by the drive mechanism 30.

[0076] The humidifying section 22 has an open, porous structure, specifically a mesh-like or sponge-like porous structure with multiple through-channels. This structure is connected to and located below the sealing section 21. The porous nature of the humidifying section 22 ensures that air can pass through smoothly, i.e., it has good air permeability. At the same time, its mesh-like or sponge-like structure has a high specific surface area, which is very conducive to the adhesion and evaporation of moisture.

[0077] When the water absorption section 23 supplies condensate to the humidification section 22, the moisture is evenly distributed on its porous surface. At this time, the fresh airflow passes through the humidification section 22 and can make full contact with the moisture, thus being effectively humidified.

[0078] In a preferred embodiment, the humidification section 22 can be made of a fiber fabric or a porous polymer material with good hydrophilicity and breathability. Compared to conventional ultrasonic atomizers or water spray nozzles, this embodiment achieves humidification through passive water absorption and evaporation, resulting in a more compact structure. It also requires no energy consumption during the humidification of fresh air and eliminates the problem of additional water mist precipitation.

[0079] The water absorption section 23 is a wicking structure used to lift the condensate. This structure is connected to the lower end of the humidification section 22 and is the part where the entire humidification assembly 20 interacts with the condensate in the water receiving tray 50. Utilizing the capillary action of the material, the wicking structure can "pump" the condensate in the water receiving tray 50 to the upper humidification section 22 without additional power, keeping the humidification section 22 continuously moist to ensure the long-lasting and stable humidification function.

[0080] This structure can be made of highly absorbent materials, such as absorbent cotton, special fiber bundles, or other materials with excellent wicking effect. This design enables a passive, self-sufficient recycling of condensate.

[0081] In summary, although the sealing section 21, humidifying section 22, and water absorption section 23 have different structures and materials, they can be integrated into a single humidifying component 20. By controlling the overall movement of this component through the drive mechanism 30, the functional characteristics of different sections can be utilized to conveniently switch between various functions such as blocking the fresh air inlet 12, introducing fresh air, and humidifying.

[0082] In one embodiment, the drive mechanism 30 includes a spool 31 connected to the sealing section 21 and a drive motor 32 for driving the spool 31 to rotate.

[0083] like Figure 4 As shown, in this embodiment, the drive motor 32 is fixedly installed on the upper end of the support 11, and its function is to provide rotational power.

[0084] The spool 31 is a rotatable shaft, one end of which is connected to the output shaft of the drive motor 32, so that it can be driven to rotate by the drive motor 32. The axis of the spool 31 is horizontal.

[0085] The uppermost end of the humidification component 20, i.e. the upper edge of the sealing section 21, is fixed to the outer peripheral surface of the roller 31.

[0086] The working process is as follows: When it is necessary to raise the humidification component 20 (for example, switching from the off state to the fresh air or fresh air humidification state), the drive motor 32 is started. The drive motor 32 drives the roller 31 to rotate in a preset direction (for example, clockwise), and the flexible humidification component 20 is gradually rolled up on the roller 31 like a roller blind, thereby realizing the overall rise relative to the fresh air inlet 12.

[0087] When it is necessary to lower the humidification component 20 (e.g., to switch modes or turn off the fresh air function), the drive motor 32 rotates in the opposite direction (e.g., counterclockwise) or is slowly released under control. The humidification component 20 unfolds smoothly from the roller 31 under its own gravity, thereby lowering its overall position relative to the fresh air inlet 12.

[0088] The combination of "drive motor 32 + roller 31" has the advantages of simple structure, low cost, and reliable operation. At the same time, by controlling the drive motor 32, the lifting position of the humidification component 20 can be precisely positioned very easily, thereby ensuring that the humidification section 22 or the sealing section 21 can accurately cover the fresh air inlet 12, and that the water absorption section 23 can accurately immerse or detach from the condensate water surface, so as to meet the switching requirements of different working modes.

[0089] In one embodiment, a filter 70 is also provided at the fresh air inlet 12.

[0090] like Figure 4 As shown, in this embodiment, the filter 70 is disposed on the path of the airflow entering the fresh air fan 13. Specifically, it can be fixedly installed in the inner cavity of the fresh air inlet 12, or directly cover the side of the fresh air inlet 12 near the outdoor side.

[0091] The main function of filter 70 is to perform preliminary filtration of the fresh air entering the air conditioner. It can effectively intercept and filter out larger suspended particles in the air, such as dust, pollen, willow catkins, insects, and other impurities, ensuring the cleanliness of the indoor air conditioner and the fresh air.

[0092] like Figures 1-6 As shown, corresponding to the above-mentioned fresh air module, this embodiment of the invention also provides an air conditioner, which includes the fresh air module 10 of the aforementioned embodiment.

[0093] like Figure 5 As shown, in this embodiment, the air conditioner includes an evaporator 41 and a drip tray 50 disposed below the evaporator 41. When the air conditioner is running in cooling mode, moisture in the air condenses on the surface of the evaporator 41 to form condensate, which drips down due to gravity and collects in the drip tray 50.

[0094] The fresh air module 10 is integrated inside the air conditioner and is used to introduce fresh air and humidify the fresh air using the aforementioned condensate. The fresh air module 10 includes a support 11, a humidification component 20, a drive mechanism 30, and a fresh air fan 13.

[0095] In this embodiment, the support portion 11 of the fresh air module 10 can utilize the existing structure inside the air conditioner, such as the partition 80 used to separate the indoor and outdoor portions, thereby achieving a compact structural layout and saving internal space. A fresh air inlet 12 is provided on the support portion 11.

[0096] The humidifying component 20 is disposed on the support portion 11 and is movable thereon to selectively cover the fresh air inlet 12. The drive mechanism 30 is connected to the humidifying component 20 and is used to drive its movement. The humidifying component 20 includes a sealing section 21, a humidifying section 22, and a water absorption section 23.

[0097] During the operation of the air conditioner, the drive mechanism 30 can drive the humidification component 20 to move according to user instructions or preset programs, so as to switch between different functional modes:

[0098] Fresh air humidification mode: The drive mechanism 30 drives the humidification component 20 to move until the humidification section 22 covers the fresh air inlet 12. In this position, the entire water absorption section 23 of the humidification component 20 or its lower half can be immersed in the condensate in the water receiving tray 50 below.

[0099] The water absorption section 23 absorbs condensate and transports it to the humidification section 22, keeping the humidification section 22 moist. At this time, the fresh air fan 13 located at the fresh air inlet 12 is activated, and fresh outdoor air is drawn in. As it flows through the moist humidification section 22, it carries moisture and forms humidified fresh air that enters the air conditioner room, thereby increasing the indoor humidity while introducing fresh air.

[0100] Pure Fresh Air Mode (No Humidification): If the user only needs to introduce fresh air without humidification, the drive mechanism 30 drives the humidification component 20 to move upward a short distance. At this position, the humidification section 22 still covers the fresh air inlet 12, but the entire component is raised relative to the inlet 12, causing its bottom water absorption section 23 to completely detach from the condensate surface in the water collection tray 50. Since the water supply is disconnected, the humidification section 22 gradually dries and remains dry. At this time, the fresh air fan 13 is activated, and fresh outdoor air flows directly into the room after passing through the dry humidification section 22, achieving a pure fresh air function without humidification.

[0101] Fresh air mode off: When fresh air is not needed, the drive mechanism 30 drives the humidification component 20 to move, causing the sealing section 21 to move downwards to completely cover the fresh air inlet 12. The sealing section 21 is an airtight structure, which can effectively seal the fresh air inlet 12, prevent the circulation of indoor and outdoor air, and ensure the normal operation of the air conditioner.

[0102] By integrating the aforementioned fresh air module 10 into the air conditioner, this embodiment not only possesses the functions of a traditional air conditioner but also utilizes its own generated condensate as a humidification water source, eliminating the need for additional water replenishment by the user and achieving integrated fresh air and humidification functions. Simultaneously, through the control of the humidification component 20 by the drive mechanism 30, integrated operation of three modes—fresh air humidification, pure fresh air, and fresh air off—is achieved. This design features a simple structure, reliable operation, and significantly improves product integration and user experience.

[0103] In one embodiment, a partition plate 80 is also included. The evaporator 41 includes an evaporator body 42 and an inlet / outlet pipe 43 connected to the evaporator body 42. The fresh air module 10 is disposed on the partition plate 80, and the air blowing direction of the fresh air fan 13 of the fresh air module 10 is towards the area where the inlet / outlet pipe 43 is located.

[0104] like Figure 5 As shown, in this embodiment, the air conditioner also includes a partition plate 80 spaced apart from the evaporator 41. This partition plate 80, as an existing structural component of the air conditioner, serves as a support and divider within the air conditioner. The fresh air module 10 is directly mounted on the partition plate 80; that is, the support portion 11 is part of the partition plate 80.

[0105] Furthermore, the evaporator 41 includes an evaporator body 42 for primary heat exchange and inlet / outlet pipes 43 connected to the evaporator body 42 for supplying refrigerant. The inlet / outlet pipes 43 are located in the edge region of the evaporator body 42. This edge region is also the edge region inside the air conditioner.

[0106] In order to pre-treat the introduced fresh air and make full use of the limited space inside the air conditioner, this embodiment has specially designed the installation position and airflow path of the fresh air module 10. Specifically, after installation, the fresh air fan 13 of the fresh air module 10 blows air towards the area where the inlet and outlet ducts 43 are located.

[0107] When the fresh air fan 13 starts, the fresh outdoor air it drives does not blow directly into the room, but first flows through the inlet and outlet ducts 43. Because the refrigerant temperature flowing through the inlet and outlet ducts 43 is low when the air conditioner is running in cooling mode, the surface temperature of these ducts is also lower than the ambient temperature.

[0108] When the warmer fresh air comes into contact with the surfaces of these low-temperature ducts (or with the surrounding area), heat exchange occurs, thus pre-cooling the fresh air. The pre-cooled fresh air then flows into the main airflow channel of the air conditioner, undergoes secondary cooling through the evaporator body 42, and is finally delivered into the room.

[0109] With this layout, the air conditioner in this embodiment pre-cools the fresh air by using the "cold source" of the evaporator 41 inlet / outlet pipe 43 while introducing fresh air, thus improving the comfort of the fresh air. Compared with the traditional solution that simply blows fresh air directly into the room, this embodiment can make full use of the low-temperature surface conditions of the inlet / outlet pipe 43 and the evaporator body 42, so that the fresh air undergoes multi-stage temperature treatment before entering the room, resulting in better fresh air effect. Furthermore, when the fresh air humidification mode is activated, it works in conjunction with the water absorption section 23 and the humidification section 22 to further increase the indoor air humidity and improve the human comfort experience.

[0110] In one embodiment, a centrifugal fan 90 is also included, which is disposed between the partition plate 80 and the evaporator body 42. The fresh air module 10 is disposed at one edge of the partition plate 80 and located on one side of the centrifugal fan 90. An air outlet 91 is provided on the other side of the centrifugal fan 90 opposite to the fresh air module 10.

[0111] like Figure 5 As shown, in this embodiment, a centrifugal fan 90 for driving indoor air circulation is also provided between the partition plate 80 and the evaporator body 42. The relative positions of the components are arranged as follows:

[0112] The fresh air module 10, as a component for introducing fresh external air, is located at one edge of the partition 80, for example... Figure 5 The left edge is shown in the diagram. Meanwhile, in the overall horizontal layout of the air conditioner, the fresh air module 10 is located on one side of the centrifugal fan 90.

[0113] Corresponding to the position of the fresh air module 10, the air outlet 91 of the air conditioner is located on the other side of the centrifugal fan 90. That is to say, the fresh air module 10 and the air outlet 91 are located on both sides of the centrifugal fan 90, forming a layout of "fresh air entering on one side and mixed air exiting on the other side".

[0114] The operation and advantages of this layout are as follows: When the air conditioner is working, the centrifugal fan 90 rotates at high speed, creating negative pressure at its inlet, drawing in both indoor return air and pre-cooled fresh air supplied by the fresh air module 10. Before entering the centrifugal fan 90, these two airflows first undergo heat exchange by passing together through the evaporator body 42.

[0115] The cooled mixed air is then drawn into the inlet of the centrifugal fan 90 located behind the evaporator body 42. Finally, the centrifugal fan 90 pressurizes the mixed air and blows it out from the outlet 91 on its other side, evenly distributing it into the room.

[0116] In summary, this embodiment not only achieves a compact structure and makes good use of existing space by arranging the centrifugal fan 90 between the partition plate 80 and the evaporator body 42, and setting the fresh air module 10 on one side edge of the partition plate 80, but also constructs a multi-stage pre-cooled fresh air path.

[0117] Specifically, this marginalized, side-mounted layout plans an approximately "L"-shaped flow trajectory for the introduced fresh air, thereby achieving secondary or even tertiary pretreatment of the fresh air, as follows:

[0118] First-stage pre-cooling: When the fresh air humidification mode is activated, the fresh air first passes through the humidified humidification section 22. During this process, the evaporation of water absorbs heat, thus achieving the first evaporative pre-cooling of the warmer fresh air and increasing its humidity.

[0119] Second-level pre-cooling: such as Figure 5 As shown, the outdoor fresh air driven by the fresh air fan 13 first blows through the inlet and outlet ducts 43 located at the inner edge of the air conditioner. Since low-temperature refrigerant flows inside these ducts, the fresh air undergoes heat exchange here, and its temperature is reduced a second time.

[0120] Third-stage pre-cooling: After the above two-stage pre-cooling processes, the fresh airflow turns at an "L"-shaped bend before reaching the centrifugal fan 90 inlet, and mixes thoroughly with the indoor return air drawn in from the main air inlet. During this process, the fresh airflow flows through the large-area evaporator body 42, undergoing the final and most important cooling process.

[0121] This multi-stage pre-cooling process effectively avoids introducing hot outdoor fresh air into the room. It ensures that the fresh air is fully cooled and mixed before entering the main air duct, which not only improves the user's comfort experience, but also ensures the air conditioner's original high-efficiency airflow by avoiding physical obstruction to the main indoor air circulation duct, ultimately achieving perfect compatibility between the fresh air function and the air conditioner's original high performance.

[0122] In one embodiment, a base 100 is also included, and a partition 80 is disposed on the base 100 to divide the space above the base 100 into an indoor portion 101 and an outdoor portion 102; the evaporator 41 and the centrifugal fan 90 are both disposed on the indoor portion 101 and fixedly connected to the base 100, and the fresh air inlet 12 of the fresh air module 10 passes through the partition 80 to connect the indoor portion 101 and the outdoor portion 102.

[0123] like Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, the air conditioner includes a base 100, which forms the mounting base for the entire air conditioner. A partition 80 is L-shaped and vertically fixed to the base 100. This mounting method allows the partition 80 to act as a partition wall, naturally dividing the entire operating space above the base 100 into two functional areas:

[0124] The room consists of an indoor section 101 and an outdoor section 102. The outdoor section 102 is used to house components that exchange heat with the outdoor environment, such as a compressor and a condenser (not shown in the figure), and this section is directly connected to the outdoor environment. The indoor section 101 is used to house components that circulate and process air with the indoor environment, and this section is directly connected to the indoor air circulation.

[0125] In this embodiment, the evaporator 41 (specifically including the evaporator body and inlet / outlet pipes) and the centrifugal fan 90 for driving indoor air circulation are both located on the indoor side portion 101 and are fixedly connected to the base 100 by fasteners.

[0126] The support portion of the fresh air module 10 (composed of a part of the partition 80) is directly mounted on the partition 80. More specifically, the fresh air inlet 12 of the fresh air module 10 is formed through the thickness direction of the partition 80. This structure makes the fresh air inlet 12 a controllable channel, directly connecting the indoor side portion 101 and the outdoor side portion 102. When the humidification component 20 is in different positions, the airflow state of the air conditioner is as follows:

[0127] When the humidification section 22 covers the fresh air inlet 12 (fresh air humidification mode): the drive mechanism 30 drives the humidification component 20 to move to a designated position, so that the humidification section 22 exactly covers the fresh air inlet 12 of the middle partition 80. At this time, fresh air from outside enters the air conditioner from the outdoor side 102 through the fresh air inlet 12 under the action of the fresh air fan 13.

[0128] Because the humidification section 22 is connected to the lower water absorption section 23 to maintain humidity, the outside air is fully humidified when passing through the humidification section 22 before entering the indoor section 101. At this time, the outdoor section and the indoor section are connected through the fresh air inlet 12, achieving the effect of "introducing humidified fresh air".

[0129] When the sealing section 21 covers the fresh air inlet 12 (fresh air mode off): When the user does not need fresh air, the humidification component 20 moves down, causing the sealing section 21 to cover the fresh air inlet 12, forming an airtight seal. At this time, the partition 80 becomes a complete partition, and the outdoor part 102 and the indoor part 101 of the air conditioner are no longer connected at this point.

[0130] Humidification section 22 covers fresh air inlet 12, but water absorption section 23 is above the condensate water level (pure fresh air mode): In some cases, humidification section 22 covers fresh air inlet 12, but water absorption section 23 is not immersed in condensate water, causing humidification section 22 to remain dry. At this time, external fresh air enters the indoor section 101 only through the dry humidification section 22, forming a "pure fresh air" mode.

[0131] Through the above-described layout design based on the base 100 and the partition 80, this embodiment utilizes the existing structural components of the air conditioner (partition 80) to achieve the compact integration of multiple functional modules such as fresh air, cooling and humidification without increasing volume and complexity. The structure is clear and the assembly is simple.

[0132] In one embodiment, the water receiving tray 50 includes a water receiving part 51, a water absorption part 52, and an overflow part 53 connected in sequence. The water receiving part 51 is located below the evaporator 41, the water absorption part 52 is located below the fresh air module 10, and the overflow port of the overflow part 53 is lower than the upper edge of the water absorption part 52.

[0133] like Figure 5 and Figure 6 As shown, in this embodiment, the water receiving part 51 is the main area of ​​the water receiving tray 50, with the largest horizontal projected area, and is directly located below the evaporator body 42. Its main function is to collect and gather most of the condensate that condenses and drips from the surface of the evaporator body 42 during the refrigeration process.

[0134] The water-absorbing part 52 is connected to the water-receiving part 51 and is spatially positioned below the support part 11 of the fresh air module 10, that is, directly below the water-absorbing section 23 of the humidification component 20 in the fresh air module 10. Structurally, the water-absorbing part 52 can be designed as a deeper groove than the water-receiving part 51.

[0135] The function of the water absorption section 52 is as a dedicated water storage area to accommodate the water absorption section 23 of the fresh air module 10 and the humidification section 22 in the idle state, and to ensure that even when the overall water volume of the water tray 50 is not large, the water absorption section 52 can maintain a certain water depth, thereby ensuring that the water absorption section 23 can stably and continuously absorb condensate to supply the humidification section 22.

[0136] The overflow section 53 is connected to the water absorption section 52 and extends to the outdoor side section 102 of the air conditioner. Its function is to act as a safety precaution to prevent excessive condensate in the drip tray 50 from overflowing into the indoor side.

[0137] The overflow outlet of the overflow section 53 is designed to be lower than the top edge of the water absorption section 52. In this way, when condensate accumulates in the water absorption section 52 and exceeds the set water level, if the condensate continues to increase, the water level will reach the lower overflow outlet of the overflow section 53 before it overflows the top edge of the water absorption section 52 (which may cause water to overflow onto other components on the indoor side). The excess condensate can then be controlled to be discharged to the outdoor side of the air conditioner through the overflow section 53.

[0138] In summary, this design makes full use of the condensate that is already formed during the operation of the air conditioner, avoiding the need for a separate water pump or water replenishment device. At the same time, it ensures that the condensate can automatically overflow to the outdoor part 102 even in high humidity environments or when there is too much water accumulation, thus improving the reliability and safety of the entire unit.

[0139] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
