[0049] With advancements in materials technology, consumable-free humidifier cores made from rigid, non-absorbent materials such as plastics have begun to emerge. This structure enables the wet curtain assembly to be regenerable and washable without replacement. However, the humidification performance of these consumable-free humidifiers is affected by the airflow volume and the smoothness of the airflow.

[0050] In view of this, this utility model proposes a humidifier; please refer to [link / reference needed]. Figures 1 to 12 The following is a detailed description of the humidifier according to the present application, with reference to the specific accompanying drawings.

[0051] Please see Figures 1 to 3 The humidifier 100 includes a housing 1, a wet curtain assembly 2, and a fan assembly 3. The housing 1 has an air inlet 11, an air outlet 12, and a ventilation channel 13 connecting the air inlet 11 and the air outlet 12. The wet curtain assembly 2 is disposed within the ventilation channel 13 and is made of a water-resistant material. An air passage 21 is defined on its inner side, and an air inlet channel connecting its outer side to the air passage 21 is defined on its side. A water passage 23 extending vertically is provided on the wet curtain assembly 2. The fan assembly 3 is disposed within the ventilation channel 13 and is located at the upper end of the wet curtain assembly 2. The fan assembly 3 is used to drive airflow from the air inlet 11 to the air outlet 12. The horizontal cross-sectional area of ​​the air inlet opening of the fan assembly 3 is less than or equal to the horizontal cross-sectional area of ​​the air passage 21.

[0052] In the technical solution of this utility model, the humidifier 100 is composed of the wet curtain assembly 2 and the fan assembly 3 built into the housing 1. The inner side of the wet curtain assembly 2 defines the air passage 21, and the side of the wet curtain assembly 2 defines an air inlet channel connecting its outer side and the air passage 21. The fan assembly 3 is disposed at the upper end of the wet curtain assembly 2, and the air inlet end of the fan assembly 3 is disposed corresponding to the air passage 21. After the wet curtain assembly 2 receives humidifying water to form a water film, the fan assembly 3 can drive the airflow from the air inlet 11 to the air outlet 12, that is, from the outer side of the wet curtain assembly 2 through the air inlet channel to the inner side, while carrying away the humidifying water that forms a water film on the wet curtain assembly 2, thereby realizing the humidification function. Based on this, this application sets the horizontal cross-sectional area of ​​the air inlet opening of the fan assembly 3 to be no greater than the horizontal cross-sectional area of ​​the air outlet of the air passage 21, so that the air passage area of ​​the air passage 21 is not less than the air passage area of ​​the air inlet of the fan assembly 3, thereby ensuring that the fan assembly 3 has sufficient air intake and smooth airflow, thus ensuring the humidification performance of the humidifier 100 and meeting the functional requirements.

[0053] In one embodiment of the evaporative cooling pad assembly 2, the evaporative cooling pad assembly 2 includes a main body and evaporator plates 24 extending from the wall of the main body along the width direction of the evaporative cooling pad assembly 2. The main body forms a plurality of air passage holes 22 communicating with the air passage 21, and the air inlet channel includes the plurality of air passage holes 22. That is, in this embodiment, the evaporative cooling pad assembly 2 adopts an integral structural design, formed by the main body supporting a plurality of evaporator plates 24, and the evaporator plates 24 are arranged along the width direction of the main body. Thus, a plurality of air passage holes 22 are provided on the main body, and the air passage holes 22 form part of the air inlet channel, so as to satisfy the airflow from the outside of the evaporative cooling pad assembly 2 into the air passage 21 through the air inlet channel, thus satisfying the structural and functional requirements. It is understood that the evaporative cooling pad assembly 2 can be a square structure, a circular structure, etc., arranged in a ring to form the air outlet channel, and is not limited here. In this application, the evaporative cooling pad assembly 2 is mainly set as a circular structure. Based on this, the width direction of the evaporative cooling pad assembly 2 is the radial direction of the circular evaporative cooling pad assembly 2.

[0054] It is understood that the relationship between the air passage area of ​​the air passage 21 inside the wet curtain assembly 2 and the air passage area of ​​the air inlet end of the fan assembly 3 affects the smoothness of airflow, as described above. Therefore, this application sets the air passage area of ​​the air passage 21 to be no less than the air passage area of ​​the air inlet end of the fan assembly 3, thereby ensuring sufficient air intake of the fan assembly 3 and thus ensuring the humidification performance of the humidifier 100. In the airflow path, the airflow needs to enter the inner side of the wet curtain assembly 2 from the outer side of the wet curtain assembly 2 through the air passage 22. At this time, the relationship between the air passage area of ​​the air passage 22 and the cross-sectional area of ​​the air passage 21 also affects the smoothness of airflow within the humidifier 100. Therefore, in this embodiment, the total air passage area of ​​the plurality of air passages 22 is further limited to be greater than or equal to the cross-sectional area of ​​the air passage 21, thereby ensuring sufficient air intake within the air passage 21, smooth airflow, and meeting functional requirements.

[0055] In another embodiment of the evaporative cooling pad assembly 2, the evaporative cooling pad assembly 2 includes multiple curtain cores, with an air inlet channel formed between adjacent curtain cores. That is, in this embodiment, the evaporative cooling pad assembly 2 adopts a split structure design, formed by stacking multiple curtain cores. Thus, the air inlet channel is formed between adjacent curtain cores to allow airflow from the outside of the evaporative cooling pad assembly 2 into the air passage 21 via the air inlet channel, satisfying structural and functional requirements.

[0056] It is understood that in this embodiment, in the airflow path, the airflow needs to enter the inner side of the wet curtain assembly 2 from the outside through the air inlet channel. At this time, the relationship between the total air passage area of ​​the air inlet channel and the horizontal cross-sectional area of ​​the air passage also affects the smoothness of the airflow within the humidifier 100. Therefore, in this embodiment, the total air passage area of ​​the air inlet channel is further limited to be greater than or equal to the cross-sectional area of ​​the air passage 21, so as to ensure sufficient air intake and smooth airflow within the air passage 21, thus meeting the functional requirements.

[0057] In addition, please see Figures 4 to 10The evaporative cooling pad assembly 2 includes a main body and evaporator plates 24 extending from the wall of the main body along the width direction of the evaporative cooling pad assembly 2. The inner side of the main body defines the air passage 21. The evaporator plates 24 extend from the outer wall of the main body along the width direction; and / or, the evaporator plates 24 extend from the inner wall of the main body along the width direction, and the extended ends of the evaporator plates 24 extending along the width direction are projected in the height direction around the air inlet opening of the fan assembly 3. When humidifying water is introduced into the upper end of the evaporative cooling pad assembly 2, the water can flow downward under gravity after wetting the evaporator plates 24 until it flows to the bottom of the evaporative cooling pad assembly 2. The arrangement of multiple evaporator plates 24 can increase the effective surface area for water evaporation and improve the humidification effect. By setting the evaporative cooling pad assembly 2 into a cylindrical structure, the evaporative cooling pad assembly 2 is made into a whole, thereby reducing the number of parts, facilitating positioning and assembly, and making disassembly and assembly convenient. In the overall design of the evaporative cooling pad assembly 2, multiple evaporator plates 24 can be arranged only on its inner side, or only on its outer side, or on both the inner and outer sides of the evaporative cooling pad assembly 2. The choice depends on actual needs and is not limited here. It is only important to ensure that the evaporator plates 24 located on the inner wall of the main body have their inwardly extending ends projected vertically around the air inlet opening of the fan assembly 3 to avoid obstructing the airflow. This embodiment primarily proposes a scheme where multiple evaporator plates 24 are arranged on the outer side of the evaporative cooling pad assembly 2 to meet usage requirements. Furthermore, the size and shape of the multiple evaporator plates 24 can be the same or different, as long as they can achieve the effect of dispersion and airflow guidance.

[0058] Further, please refer to Figures 4 to 6 The plurality of evaporating plates 24 are formed in multiple evaporation groups arranged in a vertical direction. Each evaporation group includes a plurality of evaporating plates 24 spaced apart circumferentially along the curtain core. In each evaporation group, a water passage 23 is defined between two adjacent evaporating plates 24; and / or, at least a portion of the evaporating plates 24 have water passages 23 formed on them. The plurality of evaporating plates 24 are formed in multiple evaporation groups arranged in a vertical direction. Each evaporation group includes a plurality of evaporating plates 24 spaced apart circumferentially along the wet curtain assembly 2, that is, the plurality of evaporating plates 24 are arranged circumferentially on the surface of the wet curtain assembly 2 and stacked in a vertical direction. The number of evaporating plates 24 in each evaporation group can be the same or different.

[0059] To ensure smooth water flow from the upper evaporation group to the lower evaporation group, multiple water passages 23 should be provided in each evaporation group for water outflow. This application does not limit the formation of the water passages 23. In some embodiments, the water passage 23 is defined between two adjacent evaporation plates 24 in each evaporation group. In this case, multiple evaporation plates 24 are arranged circumferentially at intervals, forming a gap between each pair of adjacent evaporation plates 24, which constitutes the water passage 23. In the upper evaporation group, after water flows over the upper surface of each evaporation plate 24, it enters the water passage 23 from the edge of the evaporation plate 24, thus flowing naturally to the lower evaporation group.

[0060] In other embodiments, at least some of the evaporating plates 24 are provided with the water passage 23. That is, two adjacent evaporating plates 24 can be fitted with a gap or fit closely together. By forming the water passage 23 by opening through holes, notches or other structures on the surface of some of the evaporating plates 24, when water flows on the surface of the corresponding evaporating plate 24 in the upper layer of the evaporation group, it falls into the evaporation group of the next layer when it reaches the location of the water passage 23.

[0061] In this embodiment, see Figures 7 to 8 In each of the evaporation groups, some of the evaporation plates 24 are spaced apart from each other, so that water can leak through the gaps between adjacent evaporation plates 24. Some of the evaporation plates 24 are close together, or some of the evaporation plates 24 have a larger circumferential size. Therefore, a notch is opened at the edge of the evaporation plate 24 to realize the drainage function.

[0062] In one embodiment, see Figure 7 The multiple evaporating plates 24 are configured with strip-shaped and triangular structures. The strip-shaped evaporating plates 24 are arranged at intervals, and the gap between two adjacent strip-shaped evaporating plates 24 forms the water passage 23. The triangular evaporating plates 24 have two inclined and spaced notches, thereby forming the water passage 23. During operation, water flows over the multiple evaporating plates 24 and flows out from different water passages 23, thereby achieving a layer-by-layer flow guiding effect.

[0063] Further reading Figures 7 to 8 To prevent water from falling from the upper evaporator plate 24 without fully diffusing and flowing directly out of the lower water passage 23, in some embodiments, multiple water passages 23 are staggered in the vertical direction. That is, the upper water passage 23 and the lower water passage 23 are staggered in the circumferential direction, which can avoid the situation where water flows out directly without passing through the evaporator plate 24 because the water passages 23 are directly opposite each other.

[0064] In some embodiments, in two adjacent evaporation groups, each of the evaporation plates 24 in the lower evaporation group is provided corresponding to at least one of the water passages 23 in the upper evaporation group.

[0065] When the water passage 23 is formed by the gap between two adjacent evaporation plates 24, the downward projection of the upper water passage 23 can fall on the lower evaporation plate 24. Preferably, the upper water passage 23 corresponds to the middle of the lower evaporation plate 24, thereby ensuring the diffusion range of water flow on the evaporation plate 24.

[0066] When the water passage 23 is formed by opening holes in the evaporator plate 24, water guided by the two water passages 23 in the upper layer falls simultaneously at different positions of the evaporator plate 24 in the lower layer.

[0067] For details, please refer to Figures 7 to 8 In this embodiment, by arranging the multiple water channels 23 in a staggered manner in the vertical direction, each water channel 23 can correspond to the lower evaporation plate 24, thereby facilitating the flow and diffusion of water between the multiple evaporation plates 24, increasing the uniformity of water distribution, and improving the amount of humidifying water adhering to the surface.

[0068] To improve the flow guiding effect of the evaporation plate 24, the upper surface of the evaporation plate 24 can be configured as an arc-shaped surface, an inclined surface, an arched surface, etc., and this application does not impose any restrictions on this.

[0069] In this embodiment, the evaporation plate 24 is designed in an arch shape, with a high center and low sides. When the water flows down, it can be guided along the arc trajectory of the evaporation plate 24. At the same time, each of the evaporation plates 24 is designed as a thin sheet, thereby reserving enough space for the setting of the air passage 22.

[0070] Furthermore, the plurality of evaporation plates 24 and the plurality of air vents 22 are arranged alternately in the vertical direction. By staggering the evaporation plates 24 and the air vents 22, it is easier for the air to come into contact with the water film on the evaporation plates 24, thereby improving the humidification efficiency.

[0071] It should be noted that one or more evaporative cooling pads 2 can be provided. In some embodiments, multiple evaporative cooling pads 2 are provided, and the multiple evaporative cooling pads 2 are nested together sequentially. When multiple evaporative cooling pads 2 are nested together, the multiple evaporation plates 24 of each evaporative cooling pad 2 form an independent water distribution path, and the multiple nested evaporative cooling pads 2 do not affect each other when distributing water.

[0072] Since the air enters from the side of the evaporator assembly 2 and exits from the top, to prevent the evaporator plates 24 on the multiple nested evaporator assemblies 2 from blocking the airflow, in this embodiment, the evaporator plates 24 of the inner evaporator assembly 2 and the evaporator plates 24 of the outer evaporator assembly 2 are staggered vertically in two adjacent evaporator assemblies 2 in the width direction. This arrangement ensures that external air entering through the air vents 22 of the outer evaporator assembly 2 can pass through the evaporator plates 24 of the inner evaporator assembly 2, avoiding the situation where external air entering the inner evaporator assembly 2 only passes through the outer evaporator plates 24 due to the inner and outer evaporator plates 24 being directly opposite each other.

[0073] It should be noted that, for a single evaporator assembly 2, when multiple evaporator plates 24 are provided on both the inner and outer sides of the evaporator assembly 2, the inner and outer evaporator plates 24 can be corresponding or staggered. This is because when only a single evaporator assembly 2 is provided, the inner and outer evaporator plates 24 share the same air passage 22. Therefore, a reasonable configuration can be made based on a comprehensive consideration of airflow, air resistance, and evaporation efficiency.

[0074] Further, see Figure 6 In two adjacent evaporative cooling pad assemblies 2 along their width, the evaporator plate 24 of the inner evaporative cooling pad assembly 2 is correspondingly arranged with the air passage hole 22 of the outer evaporative cooling pad 2. This allows external air entering through the air passage hole 22 of the outer evaporative cooling pad 2 to be diverted to the upper and lower surfaces of the evaporator plate 24 of the inner evaporative cooling pad 2, ensuring that airflow passes over the surface of each evaporator plate 24 and increasing the effective evaporation area.

[0075] Specifically, the more evaporative cooling pads 2 are nested together, the higher the ratio of evaporation area to volume of the multiple evaporative cooling pads 2, meaning the larger the specific surface area of ​​the multiple evaporative cooling pads 2, which is beneficial for improving humidification performance. However, this also increases wind resistance. Therefore, the number of layers of evaporative cooling pads 2 needs to be balanced with the increased wind resistance. This application proposes that the number of multiple evaporative cooling pads 2 should be controlled between two and five to ensure that the increased humidification efficiency from the increased evaporative cooling pads 2 can offset the decreased humidification efficiency due to increased wind resistance. In other words, increasing the number of evaporative cooling pads 2 as a whole needs to improve the humidification performance of the humidifier 100 to meet functional requirements. See [link to relevant documentation]. Figures 4 to 6 In this embodiment, the wet curtain assembly 2 is configured as two.

[0076] In addition, in order to ensure that the total air passage area of ​​the multiple wet curtain assemblies 2 is greater than or equal to the cross-sectional area of ​​the air passage 21, thereby ensuring sufficient air intake in the air passage 21, it is necessary to ensure that the innermost wet curtain assembly 2 is located outside the air intake opening of the fan assembly 3 in the height direction.

[0077] In addition, see Figures 11 to 12 The fan assembly 3 has a cover 31 at its air inlet end. The cover 31 has multiple through holes 32. The cover 31 protects the fan assembly 3 and prevents foreign objects from entering the fan assembly 3. At the same time, the cover 31 will block the air intake of the fan assembly 3. Therefore, the air intake area of ​​the fan assembly 3 should be adjusted to the sum of the air passage areas of the multiple through holes 32 on the cover 31.

[0078] Furthermore, the impact of the cover 31 on the air inlet area of ​​the fan assembly 3 has been described above. To reduce or even eliminate this impact, in this embodiment, the cover 31 is designed to protrude downwards, so that at least a portion of the cover 31 protrudes downwards into the air passage 21, thereby increasing the sum of the air passage areas of the plurality of holes 32 on the cover 31 and meeting functional requirements. In addition, the protruding cover 31 needs to extend downwards into the central space of the wet curtain assembly 2, thus also serving a certain positioning and limiting function.

[0079] In addition, see also Figures 1 to 3 The humidifier 100 further includes a bracket 4, a water distribution tray 5, and a water tank 6. The wet curtain assembly 2 is installed on the bracket 4. The water distribution tray 5 is located above the wet curtain assembly 2, and the water distribution tray 5 has multiple water outlets arranged at intervals. The water tank 6 is located inside the housing 1 and below the wet curtain assembly 2. The water tank 6 is used to guide water to the upper end of the wet curtain assembly 2 through a water pipe, and the water tank 6 is used to receive the water flowing down through the wet curtain assembly 2.

[0080] In the technical solution of this utility model, the material of the wet curtain assembly 2 is a hydrophobic material, which can be set as plastic or metal or other hard, water-resistant materials, so that the wet curtain assembly 2 can be rinsed and cleaned after being removed, and is not easily damaged, thus meeting the consumable-free performance of the humidifier 1000.

[0081] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
