Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to a fresh air device. Background Technology

[0002] In existing fresh air systems with humidification functions, the fresh air system usually includes a water absorption component installed in the air supply channel to carry the absorbed moisture into the air supply channel and improve the humidification effect.

[0003] However, most existing water absorption components have uneven internal moisture distribution, and some areas are prone to reaching saturation too early and being unable to continue absorbing moisture. This results in a limited water absorption capacity for the components, reducing the humidification efficiency of the fresh air system during the humidification process. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide a fresh air device that overcomes or at least partially solves the above problems. It addresses the issue of insufficient water storage efficiency and humidification effect of the humidification components in existing fresh air devices, thereby increasing the water storage capacity of the water absorption components and thus improving the humidification efficiency of the fresh air device during the humidification process.

[0005] Specifically, this utility model provides a fresh air device, comprising:

[0006] The housing has an air supply channel inside, which has an air outlet connecting to the interior and an air inlet connecting to the exterior, so that air flows from the exterior to the interior.

[0007] A rotating component is rotatably disposed within the air supply channel.

[0008] A water-absorbing assembly includes a water-absorbing element and a heat-conducting element. The water-absorbing element is stacked on one side of the heat-conducting element, and the heat-conducting element has multiple through holes. The water-absorbing assembly is wrapped around the outside of the rotating element, and the water-absorbing assembly wraps around the rotating element at least once. The water-absorbing assembly is used to absorb moisture from the air entering the air supply channel.

[0009] Optionally, the water-absorbing component is wound around the rotating member at least two times.

[0010] Optionally, in each rotation of the water-absorbing assembly, the water-absorbing element is stacked on the side of the heat-conducting element opposite to the rotating element.

[0011] Optionally, in every two adjacent water-absorbing assemblies, the water-absorbing element in the inner water-absorbing assembly contacts the heat-conducting element in the outer water-absorbing assembly.

[0012] Optionally, the rotating component includes a cross-flow fan to drive airflow from the air inlet to the air outlet. The water absorption assembly is spaced apart from the cross-flow fan. Alternatively,

[0013] The rotating component is a cross-flow fan, which drives the airflow from the air inlet to the air outlet. The water absorption assembly is in contact with the cross-flow fan.

[0014] Optionally, a clamping frame is fixedly connected to the rotating member, the clamping frame is located outside the water-absorbing component, and the clamping frame and the rotating member clamp the water-absorbing component therebetween.

[0015] Optionally, the housing has a water storage chamber configured to receive and store moisture from the water absorption assembly.

[0016] The fresh air device also includes a humidification device, which is configured to humidify using water in a water storage chamber or water in a water absorption assembly.

[0017] Optionally, the water storage chamber is located below the water absorption assembly.

[0018] The water-absorbing component is spaced apart from the water-storage chamber.

[0019] Optionally, at least a portion of the water-absorbing component is located within the water storage cavity.

[0020] Optionally, the air outlet and the air inlet are respectively located on opposite sides of the water absorption assembly. The humidification device also includes a heating device located on the air inlet side of the water absorption assembly, and the heating device is configured to heat the air on the air inlet side.

[0021] Optionally, the humidification device further includes a heating device configured to heat the water storage chamber or a heat-conducting element.

[0022] Optionally, the heat-conducting element is tin foil.

[0023] Optionally, the absorbent element is made of ion exchange resin or hygroscopic porous polymer.

[0024] Optionally, the fresh air device further includes a fan, which is located on the air outlet side of the water absorption assembly.

[0025] In this novel fresh air device, when outdoor air enters the air supply duct through the air inlet, the moisture present in the air is absorbed and stored by the water absorption component. The through-hole design of the heat-conducting component allows air or moisture to pass through it, ensuring more thorough contact between the air and the water absorption component, thus improving its water absorption effect. Simultaneously, it ensures normal airflow as the air passes through the water absorption component, preventing obstruction when the air passes through the rotating component. The water absorption component is mounted on a rotatable rotating component, further enhancing its contact with the air and improving its water absorption effect. The layered design of the water absorption component and the heat-conducting component ensures a tight fit between them. When outdoor air flows through, the water absorption component absorbs moisture. Due to the tight fit between the heat-conducting and water absorption components, capillary action occurs, increasing the water storage capacity of the water absorption component and thus improving the humidification efficiency during the humidification process.

[0044] Figure 1 This is a schematic structural diagram of a fresh air device according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 5 This utility model provides a fresh air device. The fresh air device includes a housing 100, a rotating component 200, and a water absorption assembly 300.

[0045] An air supply channel 110 is formed inside the housing 100. The air supply channel 110 has an air outlet 111 that connects to the interior and an air inlet 112 that connects to the exterior, so that air flows from the exterior to the interior.

[0046] The rotating component 200 is rotatably disposed within the air supply duct 110.

[0047] The water absorption assembly 300 includes a water absorption element 310 and a heat-conducting element 320. The water absorption element 310 is stacked on one side of the heat-conducting element 320, and the heat-conducting element 320 is provided with multiple through holes. The water absorption assembly 300 is wrapped around the outside of the rotating member 200, and the water absorption assembly 300 is wrapped around the rotating member 200 at least once. The water absorption assembly 300 is used to absorb moisture from the air entering the air supply channel 110.

[0048] like Figure 5 As shown, Figure 5 This is a schematic cross-sectional view of a fresh air device according to an embodiment of the present invention. The schematic diagram of the water-absorbing component 300 is only to show the specific structural position and is not a proportional representation of the actual dimensions. Since the water-absorbing component 300 is made of a thin and flexible material, one end of the water-absorbing component 310 and the corresponding end of the heat-conducting component 320 are preferably aligned. Of course, one end of the water-absorbing component 310 and the corresponding end of the heat-conducting component 320 can also be offset.

[0049] Most existing fresh air systems with humidification functions are pre-installed, requiring embedding into the ceiling during the renovation phase. The humidification system of these systems relies on an external water source, necessitating pre-planning and installation of dedicated water supply lines during home renovation. Leaks at water connections, especially in concealed installation locations, can be difficult to detect, potentially leading to serious consequences such as flooded ceilings and short circuits, posing significant safety hazards. This makes both initial installation and subsequent maintenance of existing fresh air systems quite difficult.

[0050] In this embodiment, when outdoor air enters the air supply duct 110 through the air inlet 112, the moisture in the air is absorbed and stored by the water absorption component 300, thereby allowing dry air to enter the room. Alternatively, when humidification is needed indoors, the stored moisture is returned to the air supply duct 110 in the form of gas or small water droplets through heating or high-frequency vibration, and then enters the room with the air. This allows the fresh air device of this embodiment to use its humidification function normally without an external water connection, improving the safety performance of the fresh air device.

[0051] The through-hole design of the heat-conducting component 320 allows air or moisture to pass through the water-absorbing component 300, ensuring more thorough contact between the air and the water-absorbing component 310 and improving the water absorption effect of the water-absorbing component 300. Simultaneously, it ensures normal airflow through the water-absorbing component 300, preventing air obstruction when passing through the rotating component 200. The water-absorbing component 300 is mounted on the rotatable rotating component 200, further enhancing its contact with air and improving its water absorption effect. The layered design of the water-absorbing component 310 and the heat-conducting component 320 in the water-absorbing component 300 ensures a tight fit between them. When outdoor air flows through, the water-absorbing component 310 absorbs moisture. Because the heat-conducting component 320 is in close contact with the water-absorbing component 310, there is a capillary effect between the water-absorbing component 310 and the heat-conducting component 320, which increases the water storage capacity of the water-absorbing component 300 and thus improves the humidification efficiency during the humidification process.

[0052] In some embodiments of this utility model, such as Figure 5 As shown, the water-absorbing component 300 is wound around the rotating component 200 at least twice.

[0053] In this embodiment, when the water-absorbing component 300 is wound around the rotating component 200 multiple times, the overall volume of the water-absorbing member 310 is increased, which not only improves the water absorption efficiency but also increases the water output of the water-absorbing component 300. Preferably, the water-absorbing component 300 is wound around the rotating component 200 at least twice.

[0054] In some embodiments of this utility model, such as Figure 5As shown, in each ring of water-absorbing assembly 300, the water-absorbing element 310 is stacked on the side of the heat-conducting element 320 away from the rotating element 200. That is to say, in each ring of water-absorbing assembly 300 wound on the rotating element 200, the water-absorbing element 310 is on the outer side. The water-absorbing element 310 on the outer side can fully contact the air to improve the water absorption efficiency.

[0055] In some embodiments of this utility model, such as Figure 5 As shown, in each pair of adjacent water-absorbing components 300, the water-absorbing element 310 in the inner water-absorbing component 300 is in contact with the heat-conducting element 320 in the outer water-absorbing component 300.

[0056] In this embodiment, both sides of the water-absorbing member 310 in the inner ring are in contact with the heat-conducting member 320, which further improves the water absorption capacity of the water-absorbing assembly 300.

[0057] Furthermore, when the heat-conducting component 320 is heated, the water-absorbing component 310 is heated more evenly, thereby further improving the evaporation effect of the water in the water-absorbing component 310 and achieving the purpose of improving humidification efficiency.

[0058] In some embodiments of this utility model, the rotating component 200 includes a cross-flow fan 210 to drive airflow from the air inlet 112 to the air outlet 111. The water absorption assembly 300 is spaced apart from the cross-flow fan 210.

[0059] In this embodiment, the rotation of the cross-flow fan 210 causes the air in the air supply channel 110 to flow from the air inlet 112 to the air outlet 111, so that the fresh air device does not need to be equipped with an additional fan 600, thereby reducing the manufacturing cost of the fresh air device.

[0060] In some embodiments of this utility model, such as Figure 5 As shown, the rotating component 200 is a cross-flow impeller 210, which drives the airflow from the air inlet 112 to the air outlet 111. The water absorption assembly 300 contacts the cross-flow impeller 210 to prevent the water absorption assembly 300 from deforming and to improve its service life. Moreover, the airflow can pass through the through hole through the water absorption assembly 300 and contact the cross-flow fan 600. The rotation of the cross-flow impeller 210 causes the air in the air supply channel 110 to flow from the air inlet 112 to the air outlet 111.

[0061] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, a clamping frame 220 is fixedly connected to the rotating component 200. The clamping frame 220 is located outside the water absorption assembly 300, and the clamping frame 220 and the rotating component 200 clamp the water absorption assembly 300 between them.

[0062] In this embodiment, the clamping frame 220 protects the water absorption assembly 300, making it less prone to deformation as it is located between the clamping frame 220 and the rotating member 200. In addition, the clamping frame 220 also has a filtering function to reduce the collision between debris entering the air supply channel 110 and the water absorption assembly 300, thereby improving the service life of the water absorption assembly 300.

[0063] In some embodiments of this utility model, such as Figure 5 As shown, the housing 100 has a water storage chamber 400 configured to receive and store moisture from the water absorption assembly 300. The water storage chamber 400 increases the water storage capacity of the fresh air unit, providing more humidification water without external water connection, thus meeting the needs of long-term humidification.

[0064] In some embodiments of this utility model, such as Figure 2 As shown, the fresh air device also includes a humidification device 500, which is configured to humidify using water in the water storage chamber 400 or water in the water absorption assembly 300.

[0065] In this embodiment, during the humidification process, the water stored in the water absorption component 300 is returned to the air supply channel 110 in the form of gas or small water droplets through heating or high-frequency vibration, and then enters the room with the air. This allows the fresh air device of this embodiment to use its humidification function normally without an external water connection. The rotating component 200 ensures that the water in the water absorption component 300 is in full contact with the air in the air supply channel 110, thereby improving the humidification effect.

[0066] In addition, the heat-conducting component 320 is made of heat-conducting material. During the humidification process, when the heat-conducting component 320 is heated, it can evenly transfer heat to the water-absorbing component 310 to improve the evaporation effect of the water in the water-absorbing component 310 and achieve the purpose of improving the humidification efficiency.

[0067] This invention can blow dry air into the room or humidify air into the room according to the user's needs, so as to meet different user needs and improve the user experience.

[0068] In some embodiments of this utility model, the water absorption assembly 300 has a water receiving tray on its lower side, and the water receiving tray is connected to the water storage cavity 400.

[0069] In this embodiment, after the water absorption component 300 absorbs water, some of the water drips down into the water receiving tray due to gravity. After a certain amount of water is stored in the water receiving tray, the water can also flow into the water storage chamber 400. This prevents water from overflowing from the water receiving tray and also increases the water storage capacity of the fresh air device, so as to provide more humidification water without connecting to an external water line, and meet the needs of long-term humidification.

[0070] In some embodiments of this utility model, the water storage cavity 400 is located below the water absorption assembly 300.

[0071] Furthermore, in some embodiments of this utility model, the water absorption component 300 and the water storage cavity 400 are arranged at intervals.

[0072] In this embodiment, after the water absorption component 300 absorbs water, some of the water drips downwards into the water storage chamber 400 under the influence of gravity. During the humidification process, the water storage chamber 400 can store water that is not in contact with the water absorption component 300. The water in the water storage chamber 400 can be returned to the air supply channel 110 in the form of gas or small water droplets by means of heating or high-frequency vibration for humidification.

[0073] Alternatively, in some embodiments of this invention, at least a portion of the water-absorbing component 300 is located within the water storage cavity 400, with water in contact with the water-absorbing component 300. The rotation of the rotating component 200 drives the water-absorbing component 300 to rotate, allowing the water-absorbing component 300 to draw water from the water storage cavity 400 into the air supply channel 110, thereby improving the humidification effect. The design of the heat-conducting component 320 enhances the water storage capacity of the water-absorbing component 300, enabling it to draw more water from the water storage cavity 400 during rotation, further improving the humidification effect.

[0074] In summary, the contact between the water absorption component 300 and the water storage chamber 400 of this utility model is not a necessary condition for humidification.

[0075] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the air outlet 111 and the air inlet 112 are respectively located on opposite sides of the water absorption assembly 300. The humidification device 500 also includes a heating device 510, which is located on the air inlet side of the water absorption assembly 300 and is configured to heat the air on the air inlet side.

[0076] In this embodiment, the heating device 510 is located on the air inlet side of the water absorption assembly 300 so that the air passing through the water absorption assembly 300 is hot air, which improves the evaporation efficiency of water and ensures the humidification effect.

[0077] In some embodiments of the present invention, the humidification device 500 further includes a heating device 510, which is configured to heat the water storage chamber 400 or the heat-conducting element 320.

[0078] In this embodiment, the heating device 510 can directly heat the water storage chamber 400 so that the water in the water storage chamber 400 can directly evaporate into a gaseous state and flow into the air supply channel 110 and enter the room with the airflow.

[0079] Alternatively, the heating device 510 can directly heat the heat-conducting component 320 through magnetic induction heating or other methods, so that the water-absorbing component 310 is heated, and the water stored in the water-absorbing component 310 is evaporated and enters the room with the airflow.

[0080] In some embodiments of this invention, the heat-conducting element 320 is tin foil. Firstly, tin foil has good thermal conductivity, ensuring uniform heating of the water-absorbing element 310 and improving the humidification efficiency of the fresh air system. Secondly, tin foil is soft, facilitating close contact with the water-absorbing element 310. Furthermore, tin foil is low in cost, which helps save on the manufacturing cost of the fresh air system.

[0081] In some embodiments of this utility model, the absorbent 310 can be made of ion exchange resin.

[0082] In some embodiments of this utility model, the absorbent 310 may also be made of a hygroscopic porous polymer.

[0083] In some embodiments of this utility model, such as Figure 1 As shown, the fresh air device also includes a fan 600, which is located on the air outlet side of the water absorption assembly 300.

[0084] In this embodiment, the fresh air device is further equipped with a fan 600, which delivers air from the air supply duct 110 to the air outlet 111. The fan 600 can facilitate airflow from the air inlet 112 to the air outlet 111 even without the cross-flow fan 210. The fan 600 can also be used in conjunction with a cross-flow fan 600 to increase the air velocity or air volume of the fresh air device.

[0085] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
