Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] An air conditioner, or air conditioner, is a device that adjusts and controls key environmental parameters such as indoor temperature, humidity, cleanliness, and airflow to meet human comfort needs or specific process environment requirements.

[0003] In related technologies, air conditioners have both a fresh air module and a humidification module. The fresh air module introduces fresh outdoor air through a fresh air fan and exhausts stale indoor air with the help of an exhaust fan, achieving efficient exchange of indoor and outdoor air and delivery of clean fresh air. The humidification module increases air humidity by delivering water vapor into the room, further optimizing the indoor comfort experience.

[0004] In related technologies, the steam humidification pipes and fresh air pipes of air conditioners converge through a mixing pipe before being discharged from the side air outlet of the air conditioner. To prevent the fresh air flow from suppressing the water vapor discharge, a baffle is usually installed inside the mixing pipe to form a physical separation in front of the side air outlet. However, the water vapor output by the humidification module is at a high temperature. When released directly from the side air outlet, it is easy for it to come into contact with users at close range, posing a clear risk of burns. At the same time, the water vapor concentrates in the lower layer of the baffle and flows downwards after leaving the pipe, which can cause condensation on the side wall of the air conditioner outlet. Utility Model Content

[0005] This application discloses an air conditioner that can quickly reduce the temperature of water vapor by using the temperature of fresh air, avoiding the risk of burns from direct contact with high-temperature water vapor and significantly improving safety.

[0006] To achieve the above objectives, this application discloses an air conditioner, comprising: chassis; The heat exchange module includes: A heat exchanger is disposed within the casing; A heat exchange duct is disposed inside the housing and corresponds to the heat exchanger. The heat exchange duct is configured to allow airflow after heat exchange with the heat exchanger. A fresh air module is disposed in the housing. The fresh air module has a fresh air duct for supplying fresh air flow, and the fresh air duct has a fresh air inlet and a fresh air outlet. Humidification module, the humidification module includes: Humidification unit, used to generate water vapor for humidification; A humidification pipe is used to transport water vapor generated by the humidification unit. The humidification pipe has a humidification inlet and a humidification outlet. The humidification inlet is connected to the humidification unit. The humidification outlet and the fresh air outlet are arranged side by side in a vertical direction, and the humidification outlet is located below the fresh air outlet. Mixing air duct assembly, the mixing air duct assembly comprising: The duct body, the humidification outlet and the fresh air outlet are both arranged opposite to and connected to the airflow inlet of the duct body, and the airflow outlet of the duct body is configured to allow airflow to flow out; A flow guide is disposed within the main body of the pipe and is inclined relative to the extension direction of the main body of the pipe. The first end of the flow guide is disposed at the airflow inlet and opposite to the humidification outlet. The second end of the flow guide extends to the airflow outlet. The height of the first end of the flow guide is lower than the height of the second end of the flow guide. The upper and lower walls of the humidification outlet are both spaced from the first end of the flow guide in the vertical direction, and the distance between the upper wall of the humidification outlet and the first end of the flow guide is greater than the distance between the lower wall of the humidification outlet and the first end of the flow guide.

[0007] Thus, the height of the first end of the guide is lower than the height of the second end of the guide, causing the guide to extend upward at an angle along the main body of the pipe. After the water vapor is discharged from the humidification outlet located below, it needs to flow along the upward-sloping guide. During this process, it will gradually mix with the fresh air discharged from the fresh air duct above. The temperature of the fresh air can quickly reduce the temperature of the water vapor. By the time the airflow is discharged from the airflow outlet of the main body of the pipe, a mixed airflow with a suitable temperature has been formed, avoiding the risk of burns from direct contact of high-temperature water vapor with the user, and significantly improving safety.

[0008] Moreover, the upward-sloping guides effectively suppress the downward swirling trend of water vapor, allowing the fresh air and water vapor to mix gradually. This reduces the formation of localized high-humidity areas and lowers the conditions for condensation. This not only prevents the internal components of the equipment from being corroded by water vapor and extends the service life of the air conditioner, but also prevents mold growth and ensures a hygienic indoor environment.

[0009] Meanwhile, the small gap between the lower wall and the guide vane allows some water vapor to be stably discharged from below the guide vane. Even when the fresh air pressure is too high, water vapor can still be discharged through the lower outlet, preventing fresh air from impacting and blocking the water vapor channel. This also ensures pressure balance within the duct body. The through-type guide vane channel ensures that water vapor maintains a stable flow pressure throughout the entire transportation process, preventing it from being blocked by fresh air due to pressure fluctuations within the duct. Ultimately, this achieves uniform distribution of water vapor indoors, resulting in more stable humidification and meeting the humidity requirements of different areas.

[0010] Optionally, the guide has at least two extension segments connected along its own extension direction, the different extension segments having different extension directions, and the at least two extension segments including a first extension segment, the first extension segment having an inclination angle relative to a first horizontal direction greater than the inclination angle of the other extension segments.

[0011] In this way, different extension sections form a continuous and gradually changing flow path through differentiated extension directions. The first extension section, as the starting part of the flow guide, extends upward at a larger angle, forming a steep start flow guide. The remaining extension sections have smaller angles and present a gentle transition extension trend, so that the flow guide as a whole forms a continuous curved surface or broken line structure that is steep at first and then gentle. This maintains the continuity of airflow guidance and achieves phased control of airflow direction through angle changes.

[0012] Optionally, at least two of the extension segments further include a second extension segment and a third extension segment, wherein the first extension segment, the second extension segment and the third extension segment are connected sequentially along the direction from the first end to the second end of the guide member, and the tilt angle of the second extension segment is smaller than the tilt angle of the third extension segment.

[0013] Thus, taking the first horizontal direction as a reference, the tilt angles of the three extension sections exhibit a gradient of first extension section > third extension section > second extension section. The first extension section (closest to the airflow inlet) maintains the maximum tilt angle, directly receiving the water vapor discharged from the humidification outlet, and quickly counteracting its initial downward swirling inertia through strong guiding force; the second extension section, as an intermediate transition section, forms a gentle buffer zone with the minimum tilt angle, allowing the airflow that has undergone strong guidance to enter a deceleration and adjustment phase, avoiding turbulence caused by sudden angle changes; the third extension section (closest to the airflow outlet) increases its tilt angle, forming a secondary guiding zone, providing a moderate upward thrust just before the airflow is discharged from the pipe, ensuring that the mixed airflow is output in a stable direction.

[0014] Optionally, the first extension segment has an inclination angle of 25° to 30° relative to the first horizontal direction; And / or, the second extension segment is tilted at an angle of 15° to 20° relative to the first horizontal direction; And / or, the third extension segment has an inclination angle of 20° to 25° relative to the first horizontal direction.

[0015] Thus, this three-stage angle gradient design further improves airflow control precision through phased regulation of airflow guidance, buffering, and focusing. It accurately suppresses airflow turbulence, eliminates localized condensation, and prevents vortices that may form in the middle of the pipe due to airflow detaching from the guide surface. The minimum angle transition in the second extension section allows the water vapor airflow, strongly guided by the first extension section, to flow smoothly against the guide surface, avoiding vortices caused by sudden angle drops. When the angle rises again in the third extension section, the airflow has already formed a stable wall-hugging flow inertia, and the secondary guidance smoothly guides it to the outlet, completely eliminating localized condensation caused by vortices in the middle of the pipe, further ensuring equipment lifespan.

[0016] Optionally, the guide is arc-shaped, and the extensions are smoothly connected.

[0017] Thus, the flow guide is arc-shaped and the extension sections are smoothly connected, making the airflow smoother, eliminating turbulence and eddies. The arc-shaped surface and smooth connection avoid abrupt changes in the direction of the airflow at the transition of the extension section. When the airflow flows along the arc-shaped surface against the wall, the guiding force it receives is continuous and uniform, and there will be no collision or detachment from the wall due to the angle, thus completely eliminating eddies in the pipe.

[0018] Optionally, the ratio of the distance between the upper wall of the humidification outlet and the first end of the guide member to the distance between the lower wall of the humidification outlet and the first end of the guide member is 4:1 to 2:1.

[0019] In this way, the distance between the upper wall of the humidification outlet and the first end of the air guide is larger, providing sufficient space for the diffusion and infiltration of the fresh air discharged from the upper fresh air outlet, allowing the fresh air to quickly cover the upper area of ​​the air guide and form convection mixing with the rising water vapor.

[0020] The distance between the lower wall of the humidifier outlet and the first end of the guide is small, accounting for one-fifth to one-third of the distance between the upper and lower walls of the humidifier outlet. If it is less than one-fifth, the resistance to water vapor flow will be too large, and it will not be able to achieve a better pressure balance effect. High-pressure fresh air will easily cause water vapor to flow back. If it is greater than one-third, it will weaken the mixing and cooling effect of the fresh air and water vapor at the top.

[0021] Optionally, along the first horizontal direction, the ratio of the extension length of the guide element to the extension length of the pipe body is 0.8:1 to 0.9:1.

[0022] Thus, the extension length of the air guide accounts for 80% to 90%, almost running through the entire mixing duct, ensuring that the air guide can control the airflow at all stages. The 10% to 20% blank space is set at the front end of the air guide, providing unconstrained space for the initial contact between fresh air and water vapor, avoiding airflow impact caused by direct guidance at the inlet. The blank space at the front end provides a buffer, reducing the accumulation of local high humidity caused by airflow impact. The arc-shaped guide at the rear end ensures that the airflow flows upward along the wall throughout the entire process, without the opportunity to swirl downward and approach the side wall of the duct, thus eliminating the risk of condensation.

[0023] Optionally, the angle between the line connecting the first end and the second end of the guide and the first horizontal direction is 18° to 22°.

[0024] Thus, the line connecting the first and second ends of the air guide maintains a gentle inclination of 18°~22°, ensuring the consistency and stability of the final airflow output direction. The included angle is limited to 18°~22° to avoid insufficient overall guiding force due to an excessively small angle, which would allow water vapor to easily swirl downwards, and to prevent a direct airflow sensation due to an excessively large angle. It also adapts to the internal space height of the mixing duct, avoiding interference with the top or bottom of the duct. The stable output direction, combined with a fully mixed airflow, results in a more uniform temperature and humidity distribution, completely eliminating the risk of burns and discomfort caused by localized high temperatures or humidity.

[0025] Optionally, the humidification pipe has a connecting section, the humidification outlet is located in the connecting section, and both the connecting section and the fresh air pipe are square pipe sections; The width of the connecting section and the fresh air duct along the second horizontal direction is equal, and the opposite side walls of the connecting section and the fresh air duct along the second horizontal direction are flush with each other. The height ratio of the fresh air duct and the connecting section along the vertical direction is 1:0.5 to 1:0.7.

[0026] Thus, the square structure of the connecting section and the fresh air duct ensures that their widths are aligned along the second horizontal direction, avoiding installation gaps or airflow leaks caused by irregular duct shapes. The straight sidewalls of the square duct section allow fresh air and water vapor to maintain laminar flow within the duct, reducing turbulent losses. Equal widths and flush sidewalls create a seamlessly aligned confluence interface between the connecting section (humidification outlet) and the fresh air duct (fresh air outlet). Airflow exiting from their respective sections can directly enter the mixing duct, avoiding airflow impact caused by width differences or sidewall misalignment. The vertical height of the fresh air duct is 1.4 to 2 times the height of the connecting section, providing ample diffusion space for fresh air while preventing uncontrolled initial water vapor diffusion due to an excessively high connecting section.

[0027] Optionally, the humidification duct further includes a main duct section; there are two connecting sections, two fresh air ducts, and two mixing air ducts, with the two connecting sections connected to the same end of the main duct section in the vertical direction, and the two connecting sections arranged on both sides of the main duct section in the first horizontal direction; the fresh air duct, the mixing air duct, and the connecting sections are arranged in a one-to-one correspondence, with the fresh air duct stacked above the corresponding connecting section; the mixing air duct is connected to the corresponding fresh air duct and the connecting section.

[0028] Thus, the dual-path parallel design allows the humidifying airflow to be discharged simultaneously from two opposite directions, doubling the coverage area compared to a single-path design. This is especially suitable for the humidification needs of large spaces, avoiding insufficient humidification in localized areas. The split flow in the main duct section ensures a balanced supply of humidifying steam from both paths. Combined with the synchronous airflow from the dual fresh air ducts, the total humidification volume is significantly increased, allowing the set humidity to be reached more quickly and optimizing humidification efficiency.

[0029] Compared with the prior art, the beneficial effects of this application are as follows: In this application, the height of the first end of the guide is lower than the height of the second end of the guide, so that the guide forms an inclined upward extension shape along the extension direction of the main body of the pipe. After the water vapor is discharged from the humidification outlet located below, it needs to flow along the inclined upward guide. During the process, it will gradually mix with the fresh air discharged from the fresh air duct above. The temperature of the fresh air can quickly reduce the temperature of the water vapor. When the airflow is discharged from the airflow outlet of the main body of the pipe, a mixed airflow with a suitable temperature has been formed, avoiding the risk of burns from direct contact of high temperature water vapor with the user, and significantly improving safety.

[0030] Moreover, the upward-sloping guides effectively suppress the downward swirling trend of water vapor, allowing the fresh air and water vapor to mix gradually. This reduces the formation of localized high-humidity areas and lowers the conditions for condensation. This not only prevents the internal components of the equipment from being corroded by water vapor and extends the service life of the air conditioner, but also prevents mold growth and ensures a hygienic indoor environment.

[0031] Meanwhile, the small gap between the lower wall and the guide vane allows some water vapor to be stably discharged from below the guide vane. Even when the fresh air pressure is too high, water vapor can still be discharged through the lower outlet, preventing fresh air from impacting and blocking the water vapor channel. This also ensures pressure balance within the duct body. The through-type guide vane channel ensures that water vapor maintains a stable flow pressure throughout the entire transportation process, preventing it from being blocked by fresh air due to pressure fluctuations within the duct. Ultimately, this achieves uniform distribution of water vapor indoors, resulting in more stable humidification and meeting the humidity requirements of different areas. Attached Figure Description

[0040] As mentioned in the background section, an air conditioner, or air conditioner, is a device that adjusts and controls key environmental parameters such as indoor temperature, humidity, cleanliness, and airflow to meet human comfort needs or specific process environment requirements.

[0041] In related technologies, air conditioners have both a fresh air module and a humidification module. The fresh air module introduces fresh outdoor air through a fresh air fan and exhausts stale indoor air with the help of an exhaust fan, achieving efficient exchange of indoor and outdoor air and delivery of clean fresh air. The humidification module increases air humidity by delivering water vapor into the room, further optimizing the indoor comfort experience.

[0042] In related technologies, the steam humidification pipes and fresh air pipes of air conditioners converge through a mixing pipe before being discharged from the side air outlet of the air conditioner. To prevent the fresh air flow from suppressing the water vapor discharge, a baffle is usually installed inside the mixing pipe to form a physical separation in front of the side air outlet. However, the water vapor output by the humidification module is at a high temperature. When released directly from the side air outlet, it is easy for it to come into contact with users at close range, posing a clear risk of burns. At the same time, the water vapor concentrates in the lower layer of the baffle and flows downwards after leaving the pipe, which can cause condensation on the side wall of the air conditioner outlet.

[0043] Based on this, the present application provides an air conditioner that can quickly reduce the temperature of water vapor by using the temperature of fresh air, avoiding the risk of burns from direct contact with high-temperature water vapor, and significantly improving safety.

[0044] The following will describe specific embodiments and appendices. Figure 1 To be continued Figure 10 The technical solution of the air conditioner in this application is described.

[0045] This application provides an air conditioner, such as... Figure 1 As shown, the air conditioner includes an indoor unit 100, which includes a housing 10. The housing 10 serves as the external frame of the entire unit, providing structural support and airflow control. It also provides installation space and protection for other components and can be decorative to blend into different interior design styles.

[0046] The indoor unit 100 of the air conditioner also includes a heat exchange module, which includes a heat exchanger and a heat exchange duct. The heat exchanger and the heat exchange duct are disposed inside the casing 10. The heat exchange duct corresponds to the heat exchanger and is configured to supply airflow after heat exchange with the heat exchanger, ensuring directional airflow after heat exchange.

[0047] The heat exchanger is the core component of the indoor unit 100 of the air conditioner, responsible for temperature regulation. It is installed inside the casing 10. The heat exchanger mainly consists of copper tubes and aluminum foil fins. In cooling mode, liquid refrigerant flows through the copper tubes, absorbing heat from the indoor air and evaporating into a gaseous state, thus lowering the indoor air temperature. In heating mode, the flow direction of the refrigerant is changed by a four-way valve, altering the function of the heat exchanger. The gaseous refrigerant condenses into a liquid state in the copper tubes, releasing heat and heating the indoor air.

[0048] The indoor unit 100 of the air conditioner also includes a fresh air module, which is installed in the casing 10. The fresh air module has a fresh air duct for supplying fresh air flow, and the fresh air duct has a fresh air inlet and a fresh air outlet. The fresh air module introduces fresh outdoor air into the room through the fresh air duct, and at the same time works with the exhaust function of the air conditioning system to exhaust the stale indoor air to the outside, thereby achieving effective replacement of indoor and outdoor air.

[0049] like Figures 2 to 6 As shown, the indoor unit 100 of the air conditioner also includes a humidification module 20. The humidification module 20 includes a humidification unit and a humidification pipe 21. The humidification unit generates water vapor for humidification; the humidification pipe 21 transports the water vapor generated by the humidification unit. The humidification pipe 21 has a humidification inlet 211 and a humidification outlet 212. The humidification inlet 211 is connected to the humidification unit, and the humidification outlet 212 and the fresh air outlet are arranged side by side in a vertical direction, with the humidification outlet 212 located below the fresh air outlet. The humidification module 20 can guide the water vapor to the humidification outlet 212 and finally discharge the water vapor into the room, thereby humidifying the indoor air, effectively increasing the indoor air humidity, and improving indoor comfort.

[0050] In some embodiments, such as Figure 1 and Figure 5 As shown, the indoor unit 100 of the air conditioner also includes a mixing duct assembly 30. The mixing duct assembly 30 includes a duct body 31, a humidification outlet 212 and a fresh air outlet, both of which are opposite to and connected to the airflow inlet 311 of the duct body 31. The airflow outlet 312 of the duct body 31 is configured to allow airflow to flow out. The duct body 31 passes through a side air outlet 11 located within the casing 10 of the air conditioner, and fresh air and water vapor are ultimately blown into the room through the side air outlet 11.

[0051] In this way, the fresh air duct of the fresh air module and the humidification duct 21 of the humidification module 20 operate independently, and finally converge through the airflow inlet 311 of the mixing duct assembly 30 to form an independent delivery and centralized exhaust airflow path, which not only preserves the functional independence of each module, but also achieves efficient integration of airflow.

[0052] In some embodiments, such as Figure 5 and Figure 6As shown, the mixing duct assembly 30 also includes a guide member 32, which is disposed within the duct body 31 and is inclined relative to the extension direction of the duct body 31. The first end 321 of the guide member 32 is disposed at the airflow inlet 311 and is disposed opposite to the humidification outlet 212. The second end 322 of the guide member 32 extends to the airflow outlet 312. The height of the first end 321 of the guide member 32 is lower than the height of the second end of the guide member 32. The upper wall 2121 and the lower wall 2122 of the humidification outlet 212 are both spaced from the first end 321 of the guide member 32 in the vertical direction. The distance h1 between the upper wall 2121 of the humidification outlet 212 and the first end 321 of the guide member 32 is greater than the distance h2 between the lower wall 2122 of the humidification outlet 212 and the first end 321 of the guide member 32.

[0053] Thus, the height of the first end 321 of the guide member 32 is lower than the height of the second end of the guide member 32, so that the guide member 32 extends upward along the extension direction of the main body of the pipe 31, and extends from the air inlet 311 to the air outlet 312, forming a through-flow guide channel, rather than a local obstruction structure, to ensure that the airflow is under control throughout the entire delivery process, so that the fresh air and water vapor change from forced collision to gradual fusion, and the mixing is more thorough and uniform.

[0054] There are gaps between the upper wall 2121 and lower wall 2122 of the humidification outlet 212 and the first end 321 of the guide 32, with the gap on the upper wall 2121 being larger than that on the lower wall 2122. The larger gap on the upper wall 2121 provides space for water vapor to flow upwards, while also providing a channel for fresh air to infiltrate downwards, achieving a gradual mixing of the two airflows rather than forced collision. After the water vapor is discharged from the lower humidification outlet 212, it needs to flow along the upward-sloping guide 32. During this process, it will gradually mix with the fresh air discharged from the upper fresh air duct. The temperature of the fresh air can quickly reduce the temperature of the water vapor. By the time the airflow is discharged from the airflow outlet 312 of the duct body 31, a mixed airflow with a suitable temperature has been formed, avoiding the risk of burns from direct contact of high-temperature water vapor with the user, and significantly improving safety.

[0055] Moreover, the guide element 32 extends upward at an angle, which guides the water vapor upward and effectively suppresses its downward swirling tendency. The gradual mixing of fresh air and water vapor allows the water vapor to quickly integrate into the fresh air, reducing the formation of local high humidity areas and lowering the conditions for condensation. This not only prevents the internal components of the equipment from being corroded by water vapor and extends the service life of the air conditioner, but also prevents mold growth and ensures a hygienic indoor environment.

[0056] Meanwhile, the small gap between the lower wall 2122 and the guide element 32 allows some water vapor to be stably discharged from below the guide element 32. When the fresh air pressure is too high, it ensures that water vapor can still be discharged through the lower outlet, preventing fresh air from impacting and blocking the water vapor channel, and also ensuring pressure balance within the main body of the duct 31. The through-type guide element 32 ensures that water vapor maintains a stable flow pressure throughout the entire transportation process, and will not be blocked by fresh air due to pressure fluctuations within the duct. Ultimately, this achieves uniform distribution of water vapor indoors, resulting in a more stable humidification effect and meeting the humidity requirements of different areas.

[0057] In some embodiments, such as Figure 5 and Figure 7 As shown, the guide member 32 has at least two extension segments connected along its own extension direction, the different extension segments have different extension directions, and the at least two extension segments include a first extension segment 323, the first extension segment 323 having an inclination angle relative to a first horizontal direction that is greater than the inclination angle of the other extension segments.

[0058] In this way, different extension sections form a continuous and gradually changing flow path through differentiated extension directions. The first extension section 323, as the starting part of the flow guide 32, extends upward at a larger angle, forming a steep start flow guide. The remaining extension sections have smaller angles and present a gentle transition extension trend, so that the flow guide 32 as a whole forms a continuous curved surface or broken line structure that is steep at first and then gentle. This maintains the continuity of airflow guidance and achieves phased control of airflow direction through angle changes.

[0059] Since the humidification outlet 212 is located below and there is a gap between it and the first end 321 of the guide 32, the first extension section 323 with a large angle can quickly receive the water vapor discharged from the humidification outlet 212, and counteract its initial downward swirling trend through the steep guiding force, while reserving a buffer space for the initial infiltration of fresh air above, so as to avoid the two airflows forming pressure collision at the inlet.

[0060] The small-angle inclination of the subsequent extension section forms a weakly guided transition zone. At this point, the water vapor has initially formed an upward flow trend. The gentle angle can avoid airflow turbulence caused by excessive constraint, while guiding it to flow steadily towards the air outlet 312. The gentle angle provides a wider flow space for the mixed airflow, reduces flow resistance, and makes the pressure evenly distributed along the extension direction of the pipe, avoiding the situation where water vapor is suppressed by fresh air, and finally achieving uniform diffusion of humidified airflow in the room.

[0061] In the diagram, the X direction is the first horizontal direction, the Y direction is the second horizontal direction, and the Z direction is the vertical direction.

[0062] In some embodiments, such as Figure 5 and Figure 7As shown, at least two extensions also include a second extension 324 and a third extension 325. The first extension 323, the second extension 324 and the third extension 325 are connected sequentially along the direction from the first end 321 to the second end 322 of the guide member 32. The tilt angle of the second extension 324 is smaller than the tilt angle of the third extension 325.

[0063] Thus, with the first horizontal direction as the reference, the tilt angles of the three extension sections present a gradient of first extension section 323 > third extension section 325 > second extension section 324. The first extension section 323 (near the airflow inlet 311) maintains the maximum tilt angle, directly receiving the water vapor discharged from the humidification outlet 212, and quickly counteracting its initial downward swirling inertia through strong guiding force; the second extension section 324, as an intermediate transition section, forms a gentle buffer zone with the minimum tilt angle, allowing the airflow that has passed through the strong guide to enter the deceleration and adjustment stage, avoiding turbulence caused by sudden angle changes; the third extension section 325 (near the airflow outlet 312) has a rising tilt angle, forming a secondary guiding zone, providing a moderate upward thrust just before the airflow is about to exit the pipe, ensuring that the mixed airflow is output in a stable direction.

[0064] This three-stage angle gradient design further improves airflow control precision through phased regulation of airflow guidance, buffering, and focusing. It accurately suppresses airflow turbulence, eliminates local condensation, and prevents vortices that may form in the middle of the pipe due to airflow detaching from the surface of the guide element 32. The minimum angle transition of the second extension section 324 allows the water vapor airflow, strongly guided by the first extension section 323, to flow smoothly against the surface of the guide element 32, avoiding vortices caused by sudden angle drops. When the angle of the third extension section 325 rises again, the airflow has formed a stable wall-hugging flow inertia, and the secondary guidance can smoothly guide it to the outlet, completely eliminating local condensation caused by vortices in the middle of the pipe, further ensuring equipment lifespan.

[0065] In some embodiments, such as Figure 7 As shown, the first extension section 323 has an inclination angle of 25° to 30° relative to the first horizontal direction. The large angle of 25° to 30° of the first extension section 323 can provide sufficient guiding force in the initial stage when the downward swirling tendency of water vapor is strongest. It can quickly receive and guide water vapor upward, and mix it with fresh air in advance in the main body of the duct 31 to achieve rapid heat exchange.

[0066] For example, the tilt angle of the first extension segment 323 relative to the first horizontal direction can be different tilt angles such as 25°, 27° or 30°, which are not limited in this application.

[0067] In some embodiments, such as Figure 7As shown, the second extension section 324 has an inclination angle of 15° to 20° relative to the first horizontal direction. The gradual angle of 15° to 20° of the second extension section 324 allows the airflow to flow smoothly along the wall, preventing eddies caused by sudden angle changes and eliminating localized high humidity areas in the middle of the pipe.

[0068] For example, the tilt angle of the second extension 324 relative to the first horizontal direction can be different tilt angles such as 15°, 18° or 20°, which are not limited in this application.

[0069] In some embodiments, such as Figure 7 As shown, the third extension section 325 has an inclination angle of 20°~25° relative to the first horizontal direction. The mid-angle of 20°~25° of the third extension section 325 ensures that the airflow is discharged in a stable upward trend, without downward swirling or wall detachment, completely eliminating sidewall condensation, and ensuring equipment life and indoor hygiene.

[0070] For example, the tilt angle of the third extension 325 relative to the first horizontal direction can be different tilt angles such as 20°, 22.5° or 25°, which are not limited in this application.

[0071] In some embodiments, such as Figure 7 As shown, the guide 32 is arc-shaped, and the extensions are smoothly connected.

[0072] Thus, the flow guide 32 is arc-shaped and the extension sections are smoothly connected, making the airflow smoother, eliminating turbulence and eddies. The arc-shaped surface and smooth connection avoid abrupt changes in the direction of the airflow at the transition of the extension section. When the airflow flows along the arc-shaped surface against the wall, the guiding force it receives is continuous and uniform, and there will be no collision or detachment from the wall due to the angle, thus completely eliminating eddies in the pipe.

[0073] Moreover, the curved surface design without dead angles allows airflow to cover all areas inside the pipe, avoiding the accumulation of high humidity caused by local air stagnation; the continuous guiding force ensures that water vapor flows upward throughout the entire process, with no possibility of downward swirling and sticking to the side wall. Combined with the uniform distribution of humidity after thorough mixing, the conditions for condensation are completely eliminated, extending the equipment's lifespan.

[0074] The curved surface allows airflow to flow smoothly, avoiding severe impacts from angles and significantly reducing impact noise. The smooth, turbulent airflow further reduces noise generated by airflow disturbances, making the air conditioner operate more quietly and improving the user experience. The curved structure also has superior mechanical properties, better withstanding long-term airflow impacts compared to a zigzag structure, reducing the risk of deformation.

[0075] In some embodiments, such as Figure 6As shown, the ratio of the distance h1 between the upper wall 2121 of the humidification outlet 212 and the first end 321 of the guide member 32 and the distance h2 between the lower wall 2122 of the humidification outlet 212 and the first end 321 of the guide member 32 is 4:1 to 2:1.

[0076] Thus, the distance between the upper wall 2121 of the humidification outlet 212 and the first end 321 of the guide 32 is larger, providing sufficient diffusion and infiltration space for the fresh air discharged from the upper fresh air outlet, allowing the fresh air to quickly cover the upper area of ​​the guide 32 and form convection mixing with the rising water vapor.

[0077] The distance between the lower wall 2122 of the humidification outlet 212 and the first end 321 of the guide 32 is small, accounting for one-fifth to one-third of the distance between the upper and lower walls 2122 of the humidification outlet 212. If it is less than one-fifth, the resistance to water vapor flow will be too large, and it will not be able to achieve a better pressure balance effect. High-pressure fresh air is prone to water vapor backflow. If it is greater than one-third, the mixing and cooling effect of the upper fresh air and water vapor will be weakened.

[0078] Therefore, the ratio of the distance between the upper wall 2121 of the humidification outlet 212 and the first end 321 of the guide 32 and the distance between the lower wall 2122 of the humidification outlet 212 and the first end 321 of the guide 32 is limited to 4:1 to 2:1, which avoids the fresh air diffusion from being out of control due to the excessive distance between the upper walls 2121 and the pressure balance effect from being poor due to the excessive distance between the lower walls 2122.

[0079] For example, the ratio of the distance h1 between the upper wall 2121 of the humidification outlet 212 and the first end 321 of the guide member 32 and the distance h2 between the lower wall 2122 of the humidification outlet 212 and the first end 321 of the guide member 32 can be 4:1, 3:1 or 2:1, and this application does not limit it.

[0080] In some embodiments, such as Figure 8 As shown, along the first horizontal direction, the ratio of the extension length L1 of the guide member 32 to the extension length L2 of the pipe body 31 is 0.8:1 to 0.9:1.

[0081] Thus, the extension length of the guide component 32 accounts for 80% to 90%, almost running through the entire mixing duct, ensuring that the guide component 32 can control the airflow at all stages. The 10% to 20% blank space is set at the front end of the guide component 32, providing an unconstrained space for the initial contact between fresh air and water vapor, avoiding airflow impact caused by direct guidance at the inlet. The blank space at the front end provides a buffer, reducing the accumulation of local high humidity caused by airflow impact. The arc-shaped guide at the rear end ensures that the airflow flows upward along the wall throughout the entire process, without the opportunity to swirl downward and approach the side wall of the duct, thus eliminating the risk of condensation.

[0082] For example, the ratio of the extension length L1 of the guide member 32 to the extension length L2 of the pipe body 31 is 0.8:1, 0.85:1 or 0.9:1, and this application does not limit it.

[0083] In some embodiments, such as Figure 7 As shown, the angle α between the line connecting the first end 321 and the second end 322 of the guide member 32 and the first horizontal direction is 18°~22°.

[0084] Thus, the line connecting the first end 321 and the second end 322 of the guide element 32 maintains a gentle inclination of 18°~22°, ensuring the consistency and stability of the final airflow output direction. The included angle is limited to 18°~22° to avoid insufficient overall guiding force due to an excessively small angle, which would allow water vapor to easily swirl downwards, and also to prevent a direct airflow sensation due to an excessively large angle. Simultaneously, it adapts to the internal space height of the mixing duct, avoiding interference with the top or bottom of the duct. The stable output direction, combined with a fully mixed airflow, results in a more uniform temperature and humidity distribution, completely eliminating the risk of burns and discomfort caused by localized high temperatures or high humidity.

[0085] For example, the angle α between the line connecting the first end 321 and the second end 322 of the guide member 32 and the first horizontal direction can be 18°, 20° or 22°, and this application does not limit it.

[0086] In some embodiments, such as Figure 9 and Figure 10 As shown, the humidification pipe 21 has a connecting section 213, the humidification outlet 212 is located in the connecting section 213, and both the connecting section 213 and the fresh air pipe are square pipe sections; The widths of the connecting section 213 and the fresh air duct along the second horizontal direction are equal, and the opposite side walls of the connecting section 213 and the fresh air duct along the second horizontal direction are flush with each other. The height ratio of the fresh air duct and the connecting section 213D2 along the vertical direction is 1:0.5~1:0.7.

[0087] like Figure 2 As shown, the fresh air duct is located above the connecting section 213 and matches the shape of the duct body 31. The height of the fresh air duct in the vertical direction is D1, and the height of the connecting section 213 in the vertical direction is D2.

[0088] Thus, the square structure of the connecting section 213 and the fresh air duct ensures that their widths are aligned along the second horizontal direction, avoiding installation gaps or airflow leakage caused by irregular duct shapes. The straight sidewalls of the square duct section allow fresh air and water vapor to maintain a laminar flow state within the duct, reducing turbulent loss. Equal widths and flush sidewalls create a seamlessly aligned confluence interface between the connecting section 213 (humidification outlet 212) and the fresh air duct (fresh air outlet). Airflow exiting from their respective duct sections can directly enter the mixing duct, avoiding airflow impact caused by width differences or sidewall misalignment. The vertical height of the fresh air duct is 1.4 to 2 times the height of the connecting section 213, providing ample diffusion space for fresh air while preventing uncontrolled initial water vapor diffusion due to excessive height of the connecting section 213.

[0089] In some embodiments, such as Figure 9 and Figure 10 As shown, the humidification pipe 21 also includes a main pipe section 214; There are two connecting sections 213, two fresh air ducts, and two pipe bodies 31. The two connecting sections 213 are connected to the same end of the main pipe section 214 in the vertical direction, and the two connecting sections 213 are arranged opposite each other on both sides of the main pipe section 214 in the second horizontal direction. The fresh air duct, the pipe body 31 and the connecting sections 213 are arranged in a one-to-one correspondence, and the fresh air duct is stacked on top of the corresponding connecting section 213. The pipe body 31 is connected to the corresponding fresh air duct and the connecting section 213.

[0090] Thus, the dual-path parallel design allows the humidifying airflow to be discharged simultaneously from two opposite directions, doubling the coverage area compared to a single-path design. This is especially suitable for the humidification needs of large spaces, avoiding insufficient humidification in localized areas. The 214-section main duct ensures a balanced supply of humidifying steam from both paths. Combined with the synchronous airflow from the dual fresh air ducts, the total humidification volume is significantly increased, allowing the set humidity to be reached more quickly and optimizing humidification efficiency.

[0091] In other embodiments, the connecting section 213, the fresh air duct, and the duct body 31 may also be one, three, four, or other quantities, which are not limited herein.
