[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] Because the wind resistance of the rotating wheel is large, the air flow speed at the rotating wheel is slow, and the indoor humidification effect is poor.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figures 1-2 As shown, this embodiment of the present disclosure provides a humidification module for a fresh air conditioner, including: a water tank 100, a cylindrical impeller 200, aluminum foil, and a fan 300. The water tank 100 has an air inlet 101 on one side wall and an air outlet 102 on the opposite side wall; the cylindrical impeller 200 is rotatably disposed inside the water tank 100, and its outer peripheral side wall has multiple first through holes 210, while the side walls at both ends of the cylindrical impeller 200 have multiple second through holes 220; the aluminum foil is disposed on the outer side wall of the cylindrical impeller 200, and its surface has multiple vent holes, with the aluminum foil covering the multiple first through holes 210; the fan 300 is disposed inside the cylindrical impeller 200.

[0040] Using the humidification module for fresh air conditioning provided in this embodiment, fresh air enters the water tank 100 through the air inlet 101, is blown onto the aluminum foil, and passes through the gap between the aluminum foil and the water tank 100 before being blown out through the air outlet 102. The cylindrical impeller 200 rotates, thereby causing the aluminum foil to rotate. Water at the bottom of the water tank 100 is then absorbed onto the surface of the aluminum foil and evaporates into the water tank 100, increasing the humidity of the fresh air. The fan 300 rotates inside the cylindrical impeller 200, thereby drawing some air from the water tank 100 into the inner side of the cylindrical impeller 200 through the second through hole 220. The air is then blown by the fan 300 onto the multiple first through holes 210 and the aluminum foil, and discharged outside the cylindrical impeller 200 through the multiple vent holes on the aluminum foil. The evaporated water vapor is also blown into the water tank 100 and then sent into the room through the air outlet 102. The rotation of fan 300 increases the air pressure inside cylindrical impeller 200 and increases the airflow speed at cylindrical impeller 200, thereby increasing the evaporation of water at cylindrical impeller 200 and improving the humidification effect on the room.

[0041] Understandably, when humidification is not needed, the cylindrical rotor 200 stops rotating, and the fan 300 can also help to bring outdoor air into the room, improving the fresh air effect.

[0042] Specifically, there is a gap between the two ends of the cylindrical rotor 200 and the inner wall of the water tank 100.

[0043] Optionally, the fan 300 is a cross-flow fan rotatably mounted inside the cylindrical impeller 200, with a length greater than or equal to half the length of the cylindrical impeller 200 and less than the length of the cylindrical impeller 200. When the length of the cross-flow fan is less than half the length of the cylindrical impeller 200, the fan's length is relatively small, resulting in a relatively small area covered by its rotation, limiting its effect on increasing the air pressure inside the cylindrical impeller 200. When the length of the cross-flow fan is greater than or equal to the length of the cylindrical impeller 200, the risk of interference between the two ends of the fan and the impeller 200 is relatively high. Therefore, a length greater than or equal to half the length of the cylindrical impeller 200 and less than the length of the impeller 200 is more reasonable. This reduces the risk of interference between the two ends of the fan and the impeller 200, while allowing for a relatively larger coverage area, effectively increasing the air pressure inside the cylindrical impeller 200, accelerating airflow, and improving the humidification effect.

[0044] Optionally, the length of the cross-flow fan is equal to nine-tenths of the length of the cylindrical impeller 200. This results in a relatively long cross-flow fan, covering a relatively large area, allowing the airflow to cover the entire length of the cylindrical impeller 200. This leads to a relatively fast airflow speed and improves the humidification effect.

[0045] Specifically, air inlets are provided on the side walls at both ends of the cross-flow fan. In this way, air in the cylindrical impeller 200 can enter the interior of the cross-flow fan from both ends through the air inlets, and then be blown by the cross-flow fan onto the aluminum foil.

[0046] Combination Figure 3 As shown, optionally, both ends of the cylindrical rotor 200 are provided with sleeve shafts 230, which are rotatably connected to the water tank 100. In this way, the stability of the connection is relatively high.

[0047] Specifically, one of the sleeve shafts 230 is connected to the output end of the first motor 240. In this way, the first motor 240 provides power for the rotation of the sleeve shaft 230, which in turn drives the cylindrical wheel 200 to rotate.

[0048] Optionally, the fan 300 has a rotating shaft 310 at both ends, and each rotating shaft 310 is rotatably connected to a sleeve shaft 230. In this way, the rotating shaft 310 passes through the sleeve shaft 230 and is rotatably connected to the sleeve shaft 230, so that the fan 300 can rotate relative to the cylindrical wheel 200 during the rotation of the cylindrical wheel 200, and the risk of interference is relatively low.

[0049] Specifically, both ends of the cross-flow fan are connected to a rotating shaft 310.

[0050] Specifically, one of the rotating shafts 310 is connected to the output terminal of the second motor 320. In this way, the second motor 320 provides power for the rotation of the rotating shaft 310 and the fan 300.

[0051] Optionally, the side walls at both ends of the cylindrical impeller 200 are also provided with multiple third through holes 221. This increases the air intake at both ends of the cylindrical impeller 200.

[0052] Alternatively, the water tank 100 and / or the cylindrical impeller 200 may be made of plastic. This reduces the weight of the water tank 100 and the cylindrical impeller 200, thus lowering the overall weight.

[0053] Optionally, the water tank 100 and / or the cylindrical impeller 200 are made of ABS plastic (Acrylonitrile Butadiene Styrene plastic). This results in a relatively low weight for the water tank 100 and the cylindrical impeller 200, reducing the overall weight.

[0054] Understandably, the water tank 100 and / or the cylindrical impeller 200 may also be made of other common plastic materials.

[0055] Combination Figure 4 As shown, optionally, the water tank 100 includes a water box 110 and a cover plate 120. The cover plate 120 covers the water box 110 and encloses the flow chamber 103 with the water box 110. The cylindrical rotor 200 is rotatably disposed within the flow chamber 103. A portion of the air inlet 101 is located on the water box 110, and another portion is located on the cover plate 120. A portion of the air outlet 102 is located on the water box 110, and another portion is located on the cover plate 120. Thus, the cover plate 120 can be opened from the water tank 100, facilitating the installation of the cylindrical rotor 200 and the fan 300 into the flow chamber 103, and also facilitating later inspection and maintenance, offering relatively high convenience.

[0056] Optionally, the water box 110 is provided with a snap-fit ​​rod 111, and the cover plate 120 is provided with a snap-fit ​​hole 121, with the snap-fit ​​rod 111 and the snap-fit ​​hole 121 engaging. In this way, the quick assembly or disassembly between the water box 110 and the cover plate 120 can be achieved through the cooperation of the snap-fit ​​rod 111 and the snap-fit ​​hole 121, which is relatively efficient.

[0057] Understandably, the water tank 110 and the cover plate 120 can also be connected and fixed with the assistance of screws.

[0058] Optionally, the water box 110 and the cover plate 120 enclose a mounting chamber 104 for mounting the second motor 320. In this way, the mounting chamber 104 is used independently for mounting the second motor 320, reducing the impact of moisture on the second motor 320 and improving the durability of the second motor 320.

[0059] Combination Figure 5 As shown, optionally, the cylindrical rotor 200 includes a first frame 250 and a second frame 260. The first frame 250 and the second frame 260 are detachably connected; wherein, a portion of the plurality of first through holes 210 is located on the first frame 250 and another portion is located on the second frame 260, and a portion of the plurality of second through holes 220 is located on the first frame 250 and another portion is located on the second frame 260. This detachable connection of the first frame 250 and the second frame 260 facilitates the installation of the fan 300, as well as inspection and maintenance, offering relatively high convenience.

[0060] Optionally, both ends of the first frame 250 and the second frame 260 enclose connecting holes 270, and each connecting hole 270 is connected to a sleeve shaft 230. In this way, the connecting holes 270 and the sleeve shaft 230 are connected in a cooperative manner, which improves the stability of the connection and facilitates the assembly and disassembly of the sleeve shaft 230 with the first frame 250 and the second frame 260, thus providing relatively high convenience.

[0061] Optionally, the first frame 250 is provided with a snap-fit ​​plate 251, and the snap-fit ​​plate 251 is provided with a snap-fit ​​block 252. The second frame 260 is provided with a snap-fit ​​groove 261, and the snap-fit ​​groove 261 engages with the snap-fit ​​block 252. In this way, the first frame 250 and the second frame 260 can be detachably connected by the engagement of the snap-fit ​​block 252 on the snap-fit ​​plate 251 and the snap-fit ​​groove 261, which facilitates the installation of the fan 300, as well as inspection and maintenance, and offers relatively high convenience.

[0062] Understandably, the second frame 260 also has a snap-fit ​​plate 251, and the snap-fit ​​plate 251 has a snap-fit ​​block 252. The first frame 250 has a snap-fit ​​groove 261, which enables the first frame 250 and the second frame 260 to be detachably connected on their two sides, resulting in relatively high connection stability. The structure is the same as the one described above, and will not be repeated here.

[0063] Combination Figure 6 As shown, optionally, a water pump 130 is provided inside the water tank 110. The input end of the water pump 130 is connected to the inside of the water tank 110, and the output end of the water pump 130 extends to the outside of the water tank 110. Thus, when there is a large amount of water in the water tank 110, the water pump 130 can be activated to drain the water from the water tank 110. If the water in the water tank 110 has been there for a long time, the water can be drained and replaced with fresh water in a timely manner to ensure the cleanliness of the water used for humidification.

[0064] Optionally, a connecting water pipe 140 is provided on one side of the water box 110, with one end of the connecting water pipe 140 extending into the inside of the water box 110. In this way, water can be added to the water box 110 through the connecting water pipe 140, reducing the risk that insufficient water in the water box 110 will affect the humidification effect.

[0065] Understandably, water pipe 140 can be directly connected to the municipal water supply, or it can be connected to the indoor unit for users to add water periodically.

[0066] Optionally, a solenoid valve 141 is provided on the water pipe 140. In this way, the solenoid valve 141 controls the opening or closing of the water pipe 140, thereby controlling the addition of water to the water box 110 and reducing the risk of overfilling.

[0067] It is understandable that the solenoid valve 141 is a conventional solenoid valve 141, which is the existing technology and conventional technical means in this field.

[0068] Optionally, a level sensor 150 is provided inside the water tank 110. This allows the level sensor 150 to determine the water level in the water tank 100. When the water level in the water tank 110 is low, the solenoid valve 141 is opened, adding water to the water tank 110 through the connecting water pipe 140. When the water level in the water tank 110 is high, the water pump 130 is turned on, discharging water from the water tank 110. This automatic adjustment of the water level in the water tank 110 provides a better user experience.

[0069] Understandably, the liquid level sensor 150 is a conventional sensor, representing existing technology and conventional techniques in this field.

[0070] Optionally, aluminum foil is wrapped around the outer wall of the cylindrical rotor 200, with 5 or more turns and 15 or fewer turns. When the number of turns is less than 5, the number of aluminum foil layers is relatively small. Since the amount of water adhering to the aluminum foil surface is fixed, fewer layers mean less water can evaporate, thus affecting the humidification effect on the fresh air. When the number of turns is less than 5, the number of aluminum foil layers is larger, resulting in greater evaporation. Because the space inside the water tank 100 is relatively small, it is easy to reach saturation humidity, leading to energy waste. Therefore, wrapping the aluminum foil around the outer wall of the cylindrical rotor 200 with 5 or more turns and 15 or fewer turns is more reasonable, allowing for a relatively larger amount of water to evaporate and reducing the risk of energy waste.

[0071] Alternatively, the aluminum foil can be wrapped 10 times. This allows for a relatively large amount of water to evaporate from the aluminum foil, thus reducing the risk of wasted energy.

[0072] Specifically, the aluminum foil is hydrophilic. This means that the hydrophilic aluminum foil adheres to water relatively well, and the amount of water adhering to it is relatively large.

[0073] Understandably, hydrophilic aluminum foil undergoes a hydrophilic treatment on top of ordinary aluminum foil, making its surface hydrophilic. This treatment allows a water film to form on the aluminum foil surface, rather than water droplets, thereby improving heat transfer efficiency and reducing corrosion. Hydrophilic aluminum foil is an existing and conventional technology.

[0074] Optionally, an electric heating element 160 is provided inside the water tank 100. By installing the electric heating element 160 inside the water tank 100, the temperature inside the water tank 100 is increased, thereby increasing the rate of water evaporation. Furthermore, aluminum foil has relatively good thermal conductivity; water adheres to the aluminum foil, resulting in a relatively large contact area for heat conduction, further increasing the rate of water evaporation and improving the indoor humidification effect.

[0075] Optionally, the electric heating element 160 is an electric heating wire 161. By placing the electric heating wire 161 inside the water tank 100, the temperature inside the water tank 100 is increased, thereby increasing the rate of water evaporation. Furthermore, aluminum foil has relatively good thermal conductivity; water adheres to the aluminum foil, resulting in a relatively large contact area for heat conduction, further increasing the rate of water evaporation and improving the humidification effect on the room. Additionally, the electric heating wire 161 is relatively small in size, reducing the space occupied inside the water tank 100.

[0076] Specifically, the electric heating wire 161 is installed inside the water box 110.

[0077] Understandably, the electric heating element 160 can also be an electric heating rod or other common electric heating element 160.

[0078] In some embodiments, a fresh air conditioning unit includes a humidification module for a fresh air conditioning unit as described in the above embodiments.

[0079] The fresh air conditioner provided by this disclosure includes a humidification module as described in the above embodiment. Fresh air enters the water tank 100 through the air inlet 101, is blown onto the aluminum foil, and passes through the gap between the aluminum foil and the water tank 100 before being blown out through the air outlet 102. The cylindrical impeller 200 rotates, thereby causing the aluminum foil to rotate. Water at the bottom of the water tank 100 is then absorbed onto the surface of the aluminum foil and evaporates into the water tank 100, increasing the humidity of the fresh air. The fan 300 rotates inside the cylindrical impeller 200, thereby drawing some air from the water tank 100 into the inside of the cylindrical impeller 200 through the second through hole 220. The air is then blown by the fan 300 onto the multiple first through holes 210 and the aluminum foil, and discharged outside the cylindrical impeller 200 through the multiple vent holes on the aluminum foil. The evaporated water vapor is also blown into the water tank 100 and then sent into the room through the air outlet 102. The rotation of fan 300 increases the air pressure inside cylindrical impeller 200 and increases the airflow speed at cylindrical impeller 200, thereby increasing the evaporation of water at cylindrical impeller 200 and improving the humidification effect on the room.

[0080] It is understandable that the humidification module used in fresh air conditioners is installed in the outdoor unit.
