Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and particularly to wet curtain assemblies and humidifiers. Background Technology

[0002] In existing humidifier structures, the wet curtain assembly is generally made up of several curtain cores stacked together. This structure requires the position of each curtain core to be aligned during installation, and the disassembly and assembly of several curtain cores is inconvenient. Summary of the Invention

[0003] The main objective of this invention is to provide a wet curtain assembly and a humidifier, which aims to make the wet curtain assembly easy to assemble and disassemble while ensuring a good humidification effect.

[0004] To achieve the above objectives, the present invention proposes an evaporative cooling pad assembly, including an evaporative cooling pad body made of a water-resistant material. The evaporative cooling pad body includes at least two tubular curtain cores, which are nested together in sequence. The inner side of each curtain core defines an air passage that is open in the vertical direction. The air passage is used to correspond to a fan assembly. The side surface of each curtain core has multiple air holes that communicate with the air passage. The side wall of each curtain core has multiple evaporation fins extending along its width.

[0005] In one embodiment, a plurality of evaporating plates are formed in a plurality of evaporating groups arranged in a vertical direction, each evaporating group comprising a plurality of evaporating plates arranged at circumferential intervals along the curtain core, wherein:

[0006] In each of the evaporation groups, a water passage is defined between two adjacent evaporation plates; and / or,

[0007] At least some of the evaporation plates have water passages.

[0008] In one embodiment, the plurality of water passages are staggered vertically; and / or,

[0009] In two adjacent evaporation groups, each evaporation plate in the lower evaporation group corresponds to at least one water passage in the upper evaporation group.

[0010] In one embodiment, the plurality of evaporation plates and the plurality of air vents are arranged alternately in the vertical direction.

[0011] In one embodiment, the plurality of evaporation plates are staggered in the vertical direction.

[0012] In one embodiment, in the two fitted curtain cores, the evaporator plates of the inner curtain core and the evaporator plates of the outer curtain core are staggered in the vertical direction.

[0013] In one embodiment, in the two mating curtain cores, the evaporator fins of the inner curtain core are correspondingly arranged with the air vents of the outer curtain core.

[0014] In one embodiment, in the two mating curtain cores, a plurality of evaporation fins are provided on the sides of the two curtain cores facing each other or away from each other.

[0015] In one embodiment, in the two fitted curtain cores, a plurality of evaporation plates are provided on the inner or outer sides of the two curtain cores.

[0016] In one embodiment, the curtain core includes a plurality of curtain core panels arranged circumferentially thereon, the plurality of curtain core panels being spliced ​​together, and a plurality of evaporation plates being disposed on each of the curtain core panels.

[0017] In one embodiment, the wet curtain assembly further includes a water distribution box located above the wet curtain body. The water distribution box is used to connect to a water source. The lower end of the water distribution box has multiple water outlets arranged circumferentially. The downward projection of the multiple water outlets covers two of the curtain cores.

[0018] In one embodiment, the water distribution box includes a first water trough and a second water trough distributed along the width direction. The lower ends of the first water trough and the second water trough are provided with a plurality of water outlets. The water outlets of the first water trough and the second water trough are respectively provided for the evaporation plates of the two curtain cores.

[0019] In one embodiment, the material of the wet curtain body is a hydrophobic material; and / or,

[0020] The main body of the wet curtain is made of plastic or metal.

[0021] The present invention also proposes a humidifier, comprising:

[0022] The housing has an air inlet and an air outlet, as well as a ventilation channel connecting the air inlet and the air outlet;

[0023] The evaporative cooling pad assembly is located within the ventilation channel and in the area corresponding to the housing where the air inlet is located; and,

[0024] A water tank is disposed inside the housing and located below the wet curtain assembly. The water tank is used to guide water to the upper end of the wet curtain assembly through the water conveying assembly, and the water tank is used to receive water flowing down through the wet curtain assembly.

[0025] A fan assembly is disposed in the ventilation channel and located at the upper end of the wet curtain assembly. The fan assembly is used to drive airflow to enter from the air inlet, and flow through the air passage of the wet curtain assembly and the air passage to the air outlet.

[0026] The evaporative cooling pad assembly includes at least one evaporative cooling pad body, which is made of a water-resistant material. The evaporative cooling pad body includes at least two tubular curtain cores, which are nested together in sequence. The inner side of each curtain core defines an air passage that is open in the vertical direction. The air passage is used to correspond to a fan assembly. The side surface of each curtain core has multiple air holes that connect to the air passage. The side wall of each curtain core has multiple evaporation fins extending along its width.

[0027] In the technical solution of this invention, when water in the lower water tank is guided to the upper end of the wet curtain body, the water wets the respective evaporation plates from the upper ends of the two curtain cores and then flows downwards under gravity until it reaches the bottom of the wet curtain body. The arrangement of multiple evaporation plates increases the effective surface area for water evaporation, improving the humidification effect. By setting the curtain cores into a cylindrical structure, a single curtain core can be adapted to the height of the wet curtain body, facilitating positioning and easy assembly / disassembly. The multiple evaporation plates of each curtain core form an independent water distribution path, and the two fitted curtain cores do not affect each other when distributing water, allowing water to spread quickly when introduced into the wet curtain body. At the same time, the two curtain cores are easy to clean by disassembling and assembling. Attached Figure Description

[0044] A mist-free humidifier is a new type of humidifier that humidifies the environment by blowing water from a wet curtain into the surrounding air. The humidifier uses a water pump to draw water from the tank to the top of the wet curtain for humidification. When the wet curtain or filter is saturated, excess water flows back to the tank at the bottom, and the pump circulates the water through the wet curtain. Existing wet curtains are generally made of absorbent cotton, fabric, or paperboard, which have the following problems: they are prone to cracking after prolonged soaking; bacteria can easily grow inside the wet curtain, and with the fan blowing, bacteria can easily disperse into the air along with the moisture, potentially affecting the user's health if inhaled; wet curtains need to be replaced, resulting in high production and maintenance costs and a relatively complex manufacturing process.

[0045] Using rigid materials such as plastic as the base material instead of traditional spunlace fabric wet curtains can reduce problems such as bacterial growth, and users can clean them themselves without replacing them during use.

[0046] However, in terms of structural design, the core structure is generally composed of several stacked core components, which requires each layer to be aligned during installation. For absorbent wet curtains, replacement is difficult; for washable wet curtains, disassembly and washing are inconvenient for users.

[0047] In view of this, the present invention improves the structure of the evaporative cooling pad and provides an evaporative cooling pad assembly that can reduce the number of parts in the evaporative cooling pad assembly and facilitate disassembly and assembly.

[0048] Please refer to Figures 1 to 3 The evaporative cooling pad assembly 100 includes an evaporative cooling pad body 1, which includes at least two tubular curtain cores 11. The two curtain cores 11 are nested together in sequence. The inner side of the curtain core 11 defines an air passage 113 that is open in the vertical direction. The air passage 113 is used to correspond to the fan assembly 400. The side surface of the curtain core 11 is provided with a plurality of air passage holes 111 that connect to the air passage 113. The side wall of the curtain core 11 has a plurality of evaporation plates 112 extending in the width direction.

[0049] In the technical solution of this invention, when water in the lower water tank 300 is guided to the upper end of the wet curtain body 1, the water immerses its respective evaporation plates 112 from the upper ends of the two curtain cores 11, and then flows downward under the action of gravity until it reaches the bottom of the wet curtain body 1. The arrangement of multiple evaporation plates 112 can increase the effective surface area for water evaporation and improve the humidification effect. By setting the curtain core 11 into a cylindrical structure, a single curtain core 11 can be adapted to the height of the wet curtain body 1, which is convenient for positioning and assembly, and easy to disassemble and assemble. The multiple evaporation plates 112 of each curtain core 11 form an independent water distribution path. The two curtain cores 11 that are fitted together do not affect each other when distributing water, so that water can spread out quickly when it is introduced into the wet curtain body 1. At the same time, the disassembly and assembly of the two curtain cores 11 facilitates cleaning.

[0050] Correspondingly, when the air passage 113 has a circular cross-section, or when the curtain core 11 has a circular structure, the corresponding evaporator 112 extends radially.

[0051] It should be understood that, since the evaporative cooling pad 1 achieves water guidance and diversion through the interlocking of two curtain cores 11, the total evaporation area of ​​the evaporative cooling pad 1 is shared by the two curtain cores 11. Under the premise of meeting the humidification efficiency of the evaporative cooling pad 1, the interlocking of the two curtain cores allows for corresponding control of the radial dimensions of the evaporation plates on each curtain core, thus reducing the processing difficulty of a single curtain core 11. Simultaneously, the reasonable arrangement of the air passages 111 on the two curtain cores 11 can adjust the air resistance, allowing the air to remain in the evaporative cooling pad 1 for a longer time, thereby improving the humidification effect of the evaporative cooling pad assembly 100.

[0052] For absorbent substrates, materials such as spunlace fabric, 3D fiber cloth, and corrugated paper are commonly used. These materials will show damage after a certain period of use, thus requiring periodic replacement. In the technical solution of this invention, the main body 1 of the evaporative cooling pad is made of a water-resistant material. This material can be repeatedly washed and maintains its physical / chemical stability under conditions such as soaking, rubbing, and washing. Combined with the material's water resistance, abrasion resistance, and chemical resistance, it has a longer lifespan, allowing the evaporative cooling pad to achieve a consumable-free effect throughout its service life. Furthermore, the main body 1 of the evaporative cooling pad is made of a hydrophobic material, specifically a rigid material such as plastic or metal, allowing the core 11 to be removed for rinsing and cleaning.

[0053] The tubular structure of the curtain core 11 is not limited; it can be a cylinder, a square cylinder, or other regular or irregular tubular shape. The tubular structure is only a type of its shape and does not limit its specific cross-sectional shape.

[0054] When designing a single curtain core 11, multiple evaporator fins 112 can be installed only on the inner side or only on the outer side. Please refer to [reference needed]. Figure 7 Evaporation plates 112 can also be provided on both the inner and outer sides of the curtain core 11. The size and shape of the multiple evaporation plates 112 can be the same or different, as long as they can play a role in dispersing and guiding the airflow.

[0055] Please refer to Figure 4 Multiple evaporator plates 112 are formed in multiple evaporation groups arranged in the vertical direction. Each evaporation group includes multiple evaporator plates 112 arranged at intervals along the circumference of the curtain core 11. That is, the multiple evaporator plates 112 are arranged in a circumferential direction on the surface of the curtain core 11 and are stacked in the vertical direction. The number of evaporator plates 112 in each evaporation group can be the same or different.

[0056] To ensure smooth water flow from the upper evaporation group to the lower evaporation group, multiple water passages 12 should be provided in each evaporation group for water outflow. This invention does not limit the formation of the water passages 12. In some embodiments, a water passage 12 is defined between two adjacent evaporation plates 112 in each evaporation group. In this case, multiple evaporation plates 112 are arranged circumferentially at intervals, forming a gap between each pair of adjacent evaporation plates 112, which constitutes the water passage 12. In the upper evaporation group, after water flows over the upper surface of each evaporation plate 112, it enters the water passage 12 from the edge of the evaporation plate 112 and flows naturally to the next evaporation group.

[0057] In other embodiments, at least some of the evaporation plates 112 are provided with water passages 12. That is, two adjacent evaporation plates 112 can be fitted with a gap or fit closely together. By forming water passages 12 by forming through holes, notches or other structures on the surface of some of the evaporation plates 112, water in the upper evaporation group flows on the surface of the corresponding evaporation plate 112 and falls into the evaporation group of the first layer when it flows to the location of the water passage 12.

[0058] In this embodiment, in each evaporation group, some evaporation plates 112 are spaced apart from each other, so that water can leak through the gap between adjacent evaporation plates 112. Some evaporation plates 112 are close together, or some evaporation plates 112 have a larger circumferential size. Therefore, a notch is opened at the edge of the evaporation plate 112 to realize the drainage function.

[0059] Furthermore, to facilitate water distribution, multiple evaporation plates can be staggered vertically. This staggered arrangement of the evaporation plates facilitates water distribution in both vertical and horizontal directions.

[0060] Please refer to Figure 4 In one embodiment, multiple evaporator plates 112 are configured as strip-shaped and triangular structures. The strip-shaped evaporator plates 112 are arranged at intervals, and a water passage 12 is formed in the gap between two adjacent strip-shaped evaporator plates 112. The triangular evaporator plates 112 have two inclined and spaced notches, thereby forming the water passage 12. During operation, water flows over the multiple evaporator plates 112 and flows out from different water passages 12, thereby achieving a layer-by-layer flow guiding effect.

[0061] To prevent water from falling from the upper evaporator plate 112 without fully diffusing and flowing directly out of the lower water passage 12, in some embodiments, multiple water passages 12 are staggered in the vertical direction, that is, the upper water passage 12 and the lower water passage 12 are staggered in the circumferential direction, which can avoid water from being directly discharged without passing through the evaporator plate 112 because the water passages 12 are directly facing each other.

[0062] In some embodiments, in two adjacent evaporation groups, each evaporation plate 112 in the lower evaporation group corresponds to at least one water passage 12 in the upper evaporation group.

[0063] When the water passage 12 is formed by the gap between two adjacent evaporation plates 112, the downward projection of the upper water passage 12 can fall on the lower evaporation plate 112. Preferably, the upper water passage 12 corresponds to the middle of the lower evaporation plate 112, thereby ensuring the diffusion range of water flow on the evaporation plate 112.

[0064] When the water passage 12 is formed by opening holes in the evaporator plate 112, the water guided by the two water passages 12 in the upper layer falls simultaneously at different positions on one side of the evaporator plate 112 in the lower layer.

[0065] Specifically, in this embodiment, by arranging multiple water channels 12 in a staggered manner in the vertical direction, each water channel 12 can correspond to the lower evaporation plate 112, thereby facilitating the flow and diffusion of water between multiple evaporation plates 112, increasing the uniformity of water distribution, and improving the amount of water adhering.

[0066] To improve the flow guiding effect of the evaporator plate 112, the upper surface of the evaporator plate 112 can be configured as an arc surface, a slope surface, a ︿-shaped surface, etc., and the present invention does not limit this.

[0067] In this embodiment, the evaporator 112 is even arc-shaped, with a high center and low sides. When the water flows down, it can be guided along the arc-shaped trajectory of the evaporator 112. At the same time, each evaporator 112 is designed as a thin sheet, thereby reserving enough space for the setting of the air passage 111.

[0068] Referring to the figure, multiple evaporator plates 112 and multiple air vents 111 are arranged alternately in the vertical direction. By staggering the evaporator plates 112 and air vents 111, it is easier for the air to come into contact with the water film on the evaporator plates 112, thereby improving the humidification efficiency.

[0069] It should be noted that the number of curtain cores 11 can also be set to more, with multiple curtain cores 11 nested together in sequence. The number of curtain cores 11 should be reasonably set to match the size of the housing 200 and the humidification requirements.

[0070] Please refer to Figure 3 and Figure 5Since the air enters from the side of the wet curtain body 1 and exits from the top, to prevent the evaporation plates 112 on the multiple interlocking curtain cores 11 from blocking each other and thus improving the air intake effect, in this embodiment, in two adjacent curtain cores 11 in the radial direction of the wet curtain body 1, the evaporation plates 112 of the inner curtain core 11 are staggered vertically from those of the outer curtain core 11. This arrangement allows external air entering through the air vents 111 of the outer curtain core 11 to pass through the evaporation plates 112 of the inner curtain core 11, preventing external air from only passing through one side of the inner evaporation plates 112 after entering the inner side due to the evaporation plates 112 of the inner and outer curtain cores 11 being directly opposite each other. This arrangement also adjusts the wind resistance of the two layers of curtain cores 11, resulting in a longer residence time of the air through the two curtain cores 11 and a larger coverage area, thereby improving the humidification effect.

[0071] For further details, please refer to Figure 3 In each curtain core 11, the air passage 111 is located between two adjacent evaporator plates 112 in the vertical direction. At this time, when the air passes through the air passage 111, it can contact the evaporator plates 112 in the vertical direction respectively, thereby increasing the contact area between the evaporator plates 112 and the air.

[0072] It should be noted that, for a single curtain core 11, when multiple evaporator fins 112 are provided on both the inner and outer sides of the curtain core 11, the inner and outer evaporator fins 112 can be aligned or staggered. This is because, in the single curtain core 11 structure, the inner and outer evaporator fins 112 share the same air passage 111. Therefore, a reasonable arrangement can be made based on a comprehensive consideration of air intake volume, air resistance, and evaporation efficiency.

[0073] Furthermore, in the radial direction of two adjacent curtain cores 11 of the wet curtain body 1, the evaporator fins 112 of the inner curtain core 11 are correspondingly arranged with the air passage holes 11 of the outer curtain core 11. This allows external air to enter through the air passage holes 111 of the outer curtain core 11 and be diverted to the upper and lower surfaces of the evaporator fins 112 of the inner curtain core 11, thereby ensuring that airflow passes over the surface of each evaporator fin 112 and increasing the effective evaporation area.

[0074] Based on the above embodiments, in two adjacent curtain cores 11 in the radial direction of the wet curtain body 1, the design of the evaporator plates 112 of the two curtain cores 11 can be the same or different.

[0075] In one embodiment, multiple evaporation plates 112 are provided on the sides of the two curtain cores 11 facing each other. That is, multiple evaporation plates 112 are provided on the outer side of the inner curtain core 11 and multiple evaporation plates 112 are provided on the inner side of the outer curtain core 11. When the two curtain cores 11 are assembled, the evaporation plates 112 face each other. In this structure, water can flow in the space between the two curtain cores 11. Even if water splashes when one curtain core 11 guides water, it can fall onto the evaporation plates 112 of the other curtain core 11.

[0076] In another embodiment, multiple evaporation plates 112 are provided on the sides of the two curtain cores 11 facing away from each other, that is, multiple evaporation plates 112 are provided on the inner side of the inner curtain core 11 and multiple evaporation plates 112 are provided on the outer side of the outer curtain core 11. The cylinder walls of the two curtain cores 11 are opposite to each other, and water flows in the space between the two curtain cores 11 facing away from each other.

[0077] In another embodiment, the evaporator plates 112 of the two curtain cores 11 are positioned in the same place, that is, multiple evaporator plates 112 are provided on the inner or outer sides of the two curtain cores 11.

[0078] In other embodiments, one of the curtain cores 11 is provided with a plurality of evaporation plates 112 on one side in the inward and outward directions, and the other curtain core 11 is provided with a plurality of evaporation plates 112 on both sides in the inward and outward directions.

[0079] The combination of the multiple cylindrical curtain cores 11 described above can be reasonably set according to the actual space design and their coordination with other parts.

[0080] It should be understood that the curtain core 11 and the evaporator 112 can be integrally molded. Considering the manufacturing process, in some embodiments, please refer to... Figure 6 The curtain core 11 is formed by splicing together multiple curtain core panels 13, with multiple evaporator fins 112 installed on each curtain core panel 13. That is, multiple curtain core panels 13 are first processed using a one-piece molding process, and then connected into a cylindrical structure using fasteners, slots, or other fitting methods to obtain the curtain core 11. This structural form is easy to manufacture. It should be understood that each curtain core panel 13 should be arc-shaped.

[0081] To ensure uniform water distribution, a water distribution box 2 is installed above the main body 1 of the wet curtain. The water distribution box 2 is used to connect to the water source. Multiple water outlets 21 arranged circumferentially are opened at the lower end of the water distribution box 2. The downward projection of the multiple water outlets 21 covers the two curtain cores 11. The multiple water outlets 21 can be arranged in a single circular distribution, in which case the radial dimensions of the water outlets 21 need to be reasonably set to ensure water distribution coverage. Alternatively, two circles of multiple water outlets 21 can be arranged radially corresponding to the two curtain cores 11. It should be understood that the water distribution box 2 can hold a certain volume of water. The structural form of the water distribution box 2 is not limited; it can be a trough-shaped structure with an open upper end, or a closed structure composed of a bottom box and a top cover.

[0082] Furthermore, the water distribution box 2 includes a first and a second water trough distributed radially. Both the first and second water troughs have multiple water outlets at their lower ends, and these outlets correspond to the evaporation plates of the two curtain cores 11, respectively. It should be understood that the first and second water troughs correspond to the two curtain cores 11, ensuring that the water discharged from the corresponding water outlets 21 falls onto the evaporation plates of the corresponding curtain core 11, guaranteeing independent water distribution for the two curtain cores 11. It should also be understood that when more curtain cores 11 are provided, the number of water troughs can be increased accordingly.

[0083] Furthermore, the evaporative cooling pad assembly 100 may include a bracket 3, which has a frame structure. The bracket 3 includes an annular base plate and multiple supporting ribs. The annular base plate has multiple through holes to facilitate water flow. The annular base plate provides support and positioning for multiple curtain cores 11. The multiple supporting ribs are located on the periphery of the annular base plate and correspond to the outer walls of the multiple curtain cores 11, thereby restricting the position of the multiple curtain cores 11. The water distribution box 2 is fastened to the upper side of the bracket 3.

[0084] It should be understood that there is a gap between two adjacent curtain cores 11, and they are not closely fitted. This can be addressed by setting a corresponding limiting structure on the upper or lower side of each curtain core 11, or by setting a blocking structure on the bracket 3.

[0085] In the technical solution of the present invention, the material of the wet curtain body 1 is a hydrophobic material, which can be plastic or other rigid materials, and each curtain core 1 can be removed for rinsing and cleaning.

[0086] The present invention also proposes a humidifier 1000, which includes a wet curtain assembly 100. The specific structure of the wet curtain assembly 100 is as described in the above embodiments. Since the humidifier 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0087] For details, please refer to Figures 8 to 9The humidifier 1000 also includes a housing 200, a fan assembly 400, and a water tank 300. The housing 200 has an air inlet and an air outlet, as well as a ventilation channel connecting the air inlet and the air outlet. Specifically, an air inlet is provided on the side surface of the housing 200, and an air outlet is provided on the top of the housing 200. The inner cavity of the housing 200 forms a ventilation channel. The fan assembly 400 and the wet curtain assembly 100 are both located inside the housing 200 and are both located within the ventilation channel. The wet curtain assembly 100 is located below the fan assembly 400 and corresponds to the area of ​​the housing where the air inlet is located. The water tank 300 is located inside the housing 200 and below the wet curtain assembly 100. The water tank 300 is used to guide water to the upper end of the wet curtain assembly 100 through the water supply assembly and to receive water flowing down through the wet curtain assembly 100. The fan assembly 400 is used to drive the airflow from the air inlet to the air outlet. This allows external air to enter the air passage 113 through the air inlet of the housing 200 and the air passage holes 111 of each curtain core 1, then gather in the ventilation passage, and finally be discharged from the air outlet of the housing 200.

[0088] The air inlet on the housing 200 should be set to correspond to the evaporative cooling pad assembly 100, and the part of the housing 200 corresponding to the fan assembly 400 should not be provided with an air inlet. This is to avoid the air flowing directly from the fan assembly 400 without passing through the evaporative cooling pad assembly 100, which would result in ineffective humidification.

[0089] It should be understood that the water supply component can be configured as a water pipe 4, or other structures capable of water flow transportation. The present invention does not limit this. In this embodiment, the water pipe 4 can be located inside the wet curtain assembly 100 or outside the wet curtain assembly 100. In one embodiment, a limiting channel is formed on the side of one of the curtain cores 1 to position the water pipe 4.

[0090] Water in water pipe 4 is guided into water distribution box 2. By setting the inlet flow rate and the outlet flow rate of water distribution box 2, the water can be absorbed to a certain volume and cover all the water outlets 21 in water distribution box 2, thereby achieving a multi-directional uniform water distribution effect.

[0091] Furthermore, the humidifier 1000 also includes a base 500, which overlaps with and is fastened to the upper end of the water tank 300. The wet curtain assembly 100 is mounted on the upper end of the base 500, and the fan assembly 400 is mounted on the upper end of the wet curtain assembly 100 and extends to the base 500 through a connector and is fastened to the base 500, thus forming a stable structure.
