Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a wet curtain assembly and a humidifier. Background Technology

[0002] 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 existing consumable-free humidifier core structure design is flawed.

[0003] The core assembly consists of several curtain core components stacked one on top of the other. The water distribution effect of each curtain core component is determined by the layer above it, so the water distribution situation must be considered repeatedly. Furthermore, this substrate itself does not absorb water; if the moisture cannot be fully spread out, the humidification effect will be poor. Utility Model Content

[0004] The main purpose of this invention is to provide a wet curtain assembly and humidifier that facilitates water distribution, enhances the heat and moisture exchange between the airflow and the wet curtain assembly, and improves the humidification effect.

[0005] To achieve the above objectives, this utility model proposes a wet curtain assembly, including a wet curtain body, the wet curtain body having an air passage, and the wet curtain body including a curtain core, the curtain core including:

[0006] Supporting structure; and,

[0007] An evaporation unit is disposed on the support structure. The evaporation unit includes a plurality of evaporation plates arranged at intervals in the vertical direction. An air inlet channel is defined between two adjacent evaporation plates in the vertical direction. The air inlet channel is connected to the air passage channel. Each evaporation plate is provided with a water passage. Two adjacent water passages in the vertical direction are staggered.

[0008] In one embodiment, each of the evaporation plates is arranged at a downward angle in the direction adjacent to the water passage; and / or,

[0009] The thickness of each evaporation plate is L, where 0 < L ≤ 40 mm.

[0010] In one embodiment, the plurality of evaporating plates include adjacent first evaporating plates and second evaporating plates, the first evaporating plates and the second evaporating plates being inclined in opposite directions, such that the lower end of the first evaporating plate is disposed corresponding to the upper end of the second evaporating plate.

[0011] In one embodiment, the thickness of each of the evaporation plates is L, where 5mm ≤ L ≤ 20mm.

[0012] In one embodiment, the support structure includes at least two support portions spaced apart in a horizontal direction;

[0013] The evaporation unit is located between the two support sections.

[0014] In one embodiment, multiple support portions are provided, and an installation channel is defined between each pair of adjacent support portions;

[0015] Multiple evaporator groups are provided and are disposed in multiple installation channels. The air inlet channel is defined by two adjacent evaporator plates in the vertical direction and the wall of the corresponding installation channel.

[0016] In one embodiment, at least partially, one end of the evaporator plate has a gap with the support portion to form the water passage at the edge of the evaporator plate.

[0017] In one embodiment, multiple curtain cores are arranged at circumferential intervals, each curtain core is arranged in a block shape, and the multiple curtain cores together define an air passage that is at least open at the top.

[0018] 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 inner cavity of the water distribution box is divided to form multiple water distribution chambers. The multiple water distribution chambers include multiple first water distribution chambers corresponding to multiple curtain cores. Each first water distribution chamber has multiple water outlets at its lower end.

[0019] In one embodiment, the surface of the curtain core is provided with a hydrophilic coating.

[0020] In one embodiment, the main body of the wet curtain is made of a water-resistant material; and / or,

[0021] The main body of the evaporative cooling pad is made of a hydrophobic material; and / or,

[0022] The main body of the wet curtain is made of plastic or metal.

[0023] This utility model also proposes a humidifier, comprising:

[0024] The housing has an air inlet and an air outlet, as well as a ventilation channel connecting the air inlet and the air outlet;

[0025] The evaporative cooling pad assembly is located within the ventilation duct and in the area corresponding to the housing where the air inlet is located; and,

[0026] 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.

[0027] A fan assembly is disposed within the ventilation channel and located above the wet curtain assembly. The fan assembly is used to drive airflow to enter from the air inlet, and flow through the air inlet channel and the air passage of the wet curtain assembly to the air outlet.

[0028] The evaporative cooling pad assembly includes at least an evaporative cooling pad body, which has an air passage. The evaporative cooling pad body includes a core, which includes a support structure and an evaporation group. The evaporation group is disposed on the support structure and includes a plurality of evaporation plates arranged at intervals in the vertical direction. An air inlet channel is defined between two adjacent evaporation plates in the vertical direction and is connected to the air passage. Each evaporation plate is provided with a water passage, and two adjacent water passages in the vertical direction are staggered.

[0029] In this invention, the support unit supports the evaporator plates and increases the evaporation area. The evaporator plates themselves increase the evaporation area. The air inlet channel is formed between two adjacent evaporator plates in the vertical direction, allowing air to fully contact the water on the surface of the evaporator plates as it passes through. The water passage facilitates water flow from the upper evaporator plates to the lower ones. When water in the lower water tank flows to the upper part of the wet curtain body, it wets the evaporator plates and then flows downwards through the water passage under gravity until it reaches the bottom of the wet curtain body. The multiple evaporator plates increase the effective surface area for water evaporation, improving the humidification effect and ensuring that the water effectively wets the entire curtain core without the need for secondary water distribution. The staggered arrangement of adjacent water passages ensures that water wets the entire surface of the evaporator plates as it passes through, preventing insufficient water diffusion caused by directly aligned water passages.

[0042] 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 spraying. When the wet curtain or filter is saturated, excess water flows back to the tank at the bottom, and the pump circulates the water back to the wet curtain. Current household humidifiers generally use absorbent materials such as spunlace fabric and corrugated paper as their core. When air passes through the moistened core, the liquid water evaporates into the air due to the pressure difference of water vapor, achieving a humidifying effect. However, materials such as spunlace fabric, 3D fiber cloth, and corrugated paper are difficult to clean and maintain due to their inherent properties, have a short lifespan, require regular replacement, and are costly. Furthermore, after absorbing water, bacteria can easily grow on their surface, producing odors, which can negatively impact user health and experience.

[0043] With advancements in materials technology, wet curtains made of rigid materials such as plastics, instead of traditional spunlace fabric, can reduce bacterial growth and other problems. Users can also clean them themselves, eliminating the need for replacement during use. However, existing consumable-free humidifier cores have the following drawbacks:

[0044] The core structure design is unreasonable. The core assembly is composed of several curtain core parts stacked one on top of the other. The water distribution quality of each curtain core part is determined by the curtain core part above it. The water distribution process needs to be repeated.

[0045] If the substrate itself does not absorb water, the humidification effect will be poor if the moisture cannot be fully spread out.

[0046] Therefore, this utility model improves the structure of the wet curtain composed of hydrophobic material substrate, so that it can meet the requirements without secondary water separation.

[0047] Please refer to Figures 1 to 2 The evaporative cooling pad assembly 100 includes a evaporative cooling pad body 1, which has an air passage 11a. The evaporative cooling pad body 1 includes a curtain core 11, which includes a support structure and an evaporation group. The evaporation group is disposed on the support structure and includes a plurality of evaporation plates 112 arranged at intervals in the vertical direction. An air inlet channel 11b is defined between two adjacent evaporation plates 112 in the vertical direction. The air inlet channel 11b is connected to the air passage 11a. Each evaporation plate 112 is provided with a water passage 12, and two adjacent water passages 12 in the vertical direction are staggered.

[0048] In the technical solution of this utility model, the support part 111 serves to support the evaporator plate 112 and increase the evaporation area. The evaporator plate 112 increases the evaporation area. The air inlet channel 11b is formed between two adjacent evaporator plates 112 in the vertical direction, so that when air passes through the air inlet channel 11b, it can fully contact the water on the surface of the evaporator plate 112, ensuring the water guiding effect of the curtain core 11. The water passage 12 is set to facilitate the flow of water from the upper evaporator plate 112 to the lower layer. Specifically, when the water in the lower water tank is guided to the upper end of the wet curtain body 1, after the water wets the evaporator plate 112, it can flow downward through the water passage 12 under the action of gravity until it flows to the bottom of the wet curtain body 1. The arrangement of multiple evaporator plates 112 can increase the effective surface area for water evaporation and improve the humidification effect. Due to the staggered arrangement of two adjacent water passages 12, the water can wet the entire surface of the evaporator plate when passing through it, avoiding insufficient water diffusion caused by the water passages 12 being directly opposite each other.

[0049] Furthermore, the water passage 12 can be formed locally on the evaporator plate 112. In this case, two adjacent water passages 12 in the vertical direction can be staggered in the length direction and / or width direction of the evaporator plate 112. The water passage 12 can also pass through the side end of the evaporator plate 112. In this case, the water passages can be staggered in the width direction of the evaporator plate 112.

[0050] The size and shape of the multiple evaporation plates 112 can be the same or different, as long as they can achieve the effect of dispersion and flow guidance.

[0051] Furthermore, the thickness of each evaporator plate 112 is L, where 0 < L ≤ 40 mm. By limiting the thickness of the evaporator plate 112, its strength is ensured, thus enabling it to withstand the impact of water flow. Preferably, the thickness is set to 5 mm ≤ L ≤ 20 mm. This ensures both the structural strength of the evaporator plate 112 and allows it to have a semi-plate structure, facilitating water separation.

[0052] This utility model does not limit the structural form of each evaporator 112. In some embodiments, each evaporator 112 is inclined in the vertical direction. Specifically, each evaporator 112 is inclined downward in the direction close to the water passage 12. This arrangement allows water to be guided along the inclined direction of the evaporator 112 when the evaporator 112 is guiding the flow, so that the water flow has a good diffusion effect on the surface of the evaporator 112.

[0053] It should be understood that the water passage 12 should be located at the low water level of each evaporator plate 112 to ensure that the water is fully diffused on the surface of the evaporator plate 112 before being guided.

[0054] In other embodiments, the upper surface of each evaporator 112 can also be arranged in an arc shape, and the water in the upper layer falls from the height of the evaporator 112 and is discharged from both ends of the evaporator 112 along the arc surface, which can also satisfy the flow guiding effect.

[0055] Based on the above embodiments, the tilting directions of the multiple evaporation plates 112 can be the same or different. Please refer to... Figures 3 to 4 The plurality of evaporating plates 112 include adjacent first and second evaporating plates, which are arranged at an angle. The first and second evaporating plates are inclined in opposite directions, so that the lower end of the first evaporating plate corresponds to the upper end of the second evaporating plate. This allows water to flow from the higher part of the first evaporating plate to the lower part, then fall on the higher part of the second evaporating plate, and then be guided to the lower part of the second evaporating plate. This allows water to flow down from above the curtain core 11 along the arrangement of the evaporating plates 112, effectively wetting the first and second evaporating plates and ensuring an effective evaporation area.

[0056] It should be noted that the first evaporator and the second evaporator can be part of the water flow path, or multiple evaporators 112 can be set as multiple first evaporators and multiple second evaporators, with the two overlapping.

[0057] The wet curtain body 1 includes a plurality of curtain cores 11 arranged at intervals along the circumference. Each curtain core 11 is arranged in a block shape. The plurality of curtain cores 11 together define an air passage 11a that is open at least at the top. The side surface of each curtain core 11 forms a plurality of air inlet channels 11b that are connected to the air passage 11a.

[0058] In this invention, multiple curtain cores 11 are arranged circumferentially to form a cylindrical structure. The cylindrical structure of the wet curtain body 1 is not limited; it can be a cylinder, square cylinder, or other regular or irregular cylindrical shape. The cylindrical structure is merely a type of external shape for the wet curtain body 1, and its specific cross-sectional shape is not limited. External air enters from the outside of the cylindrical structure through multiple air inlet channels 11b and exits through the air outlet channel 11a formed on the inside of the cylindrical structure. The curtain cores 11 are arranged in a block shape, so that water, under the action of gravity, flows from the top of the wet curtain over the entire curtain core 11 and falls into the water tank below, effectively wetting the entire curtain core 11 without the need for secondary water distribution.

[0059] For absorbent substrates, the materials are usually spunlace fabric, 3D fiber cloth, corrugated paper, etc. After a certain period of use, the materials will be damaged, so they need to be replaced regularly.

[0060] In 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 its excellent water resistance, wear resistance, and chemical resistance, this results in a longer lifespan, allowing the evaporative cooling pad to operate without consumables throughout its service life. Furthermore, the main body 1 can be made of a hydrophobic material, specifically a rigid material such as plastic or metal, allowing it to be removed for rinsing and cleaning.

[0061] The support structure can be a plate structure or a frame structure. In this embodiment, the support structure includes at least two support parts 111 spaced apart in the horizontal direction. The evaporation group is located between the two support parts 111, thereby improving the overall structural strength and facilitating the fixed installation of the evaporation group.

[0062] Furthermore, the support structure includes multiple support sections 111 arranged at intervals along the horizontal direction, with each pair of adjacent support sections 111 defining an installation channel. Multiple evaporator groups are arranged within these installation channels, and two adjacent evaporator plates 112 in the vertical direction, together with the wall of the corresponding installation channel, define an air inlet channel 11b. In this configuration, each installation channel is independent, allowing water to flow downwards through multiple channels. During the water flow, some water also adheres to the wall of the support section 111. When air enters from the air inlet channel 11b, it passes simultaneously through the upper and lower surfaces of the evaporator plates 112 and the wall of the support section 111, thereby improving evaporation efficiency.

[0063] It should be noted that the arrangement of multiple evaporation plates 112 in two adjacent installation channels can be consistent or different, and this utility model does not impose any restrictions on this.

[0064] Furthermore, the multiple support parts 111 and the multiple evaporation plates 112 can be spliced ​​together. In this embodiment, the multiple support parts 111 and the multiple evaporation plates 112 are integrally formed, which facilitates assembly.

[0065] Regarding the formation of the water passage 12, in some embodiments, each evaporator 112 is provided with a water passage 12, which can be formed by partially opening the evaporator 112. In some embodiments, one end of the evaporator 112 has at least a partial gap with the support 111 to form the water passage 12 at the edge of the evaporator 112. In this case, the support 111 can also serve as a sidewall of the water passage 12, providing a certain drainage effect. For example, one end of the evaporator 112 in the horizontal direction can be connected to the corresponding support 111, and the other end can be spaced apart from the corresponding support 111, thereby forming a gap with the wall of the mounting channel, thus forming the water passage 12. Based on the staggered arrangement of adjacent water passages 12, the side ends of two adjacent evaporators 112 away from each other are recessed or notched to form a gap with the corresponding support 111.

[0066] In this embodiment, please refer to Figure 5 At least partially, one end of the evaporator 112 has a gap with the support 111 to define a water passage 12 between it and the corresponding support 111. This can be achieved by partially recessing one side of the evaporator 112 in the horizontal direction or by providing a notch at the edge of the evaporator 112. This arrangement ensures that the notch or gap and the wall of the mounting channel share the water passage 12, guaranteeing the flow rate of the water passage 12 and ensuring smooth water distribution.

[0067] To prevent water from flowing directly out of the upper water passage 12 from the lower water passage 12 without wetting the lower evaporator plate 112, based on the above embodiment, each of the two adjacent water passages 12 in the vertical direction corresponds to a portion of the evaporator plate 112, and they are staggered along both the length and width directions of the evaporator plate 112. This ensures that when water flows through, it can overflow the entire evaporator plate 112 from a diagonal direction, guaranteeing a good diffusion effect.

[0068] For example, the first evaporator and the second evaporator are tilted in different directions, and water passages 12 are provided at the ends of the first evaporator and the second evaporator that are away from each other, so that the multiple water passages 12 are staggered along the arrangement direction of the multiple support portions 111.

[0069] Please refer to Figure 5 Since the water passage 12 is only open in the vertical direction, one side wall of the evaporator 112 is open in the extension direction, that is, the water passage 12 has three side walls, and both ends of the evaporator 112 in the width direction are connected to the corresponding support 111.

[0070] Based on the above embodiments, in order to ensure that water can also pass through the connection between the evaporator 112 and the support 111, the water passages 12 that are adjacent in the vertical direction are staggered along the length of the evaporator 112. For example, the end of the upper evaporator 112 corresponding to the air inlet side is connected to the wall surface corresponding to the mounting channel, while the end away from the air inlet side is connected to only one of the walls. The end of the lower evaporator 112 corresponding to the air inlet side is connected to only one of the walls of the mounting channel, while the end away from the air inlet side is connected to the wall surface corresponding to the mounting channel.

[0071] In some embodiments, the evaporator 112 may be tilted in the vertical direction and tilted in the length direction.

[0072] In the above embodiments, the evaporation plates 112 of the block-shaped curtain core 11 are arranged in an alternating pattern. Under the action of gravity, water flows down from the top of the wet curtain along the arrangement of multiple evaporation plates 112, effectively wetting all evaporation plates 112 without the need for secondary water separation. Furthermore, the wet curtain body has no water storage structure, making it easy to dry and less prone to bacterial growth. The main body 1 of the wet curtain is composed of block-shaped curtain cores 11, making it convenient to disassemble and clean.

[0073] Furthermore, a hydrophilic coating can be provided on the surface of the curtain core 11. This facilitates the spread of water on the surface of the wet curtain body 1, improving humidification performance. This hydrophilic coating can be applied to the surface of the support structure and / or the evaporator 112, and can be achieved by attaching hydrophilic materials or by electrostatic flocking.

[0074] To ensure even 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, and multiple water outlets 21 are opened at the lower end of the water distribution box 2. The downward projection of the multiple water outlets 21 falls on the corresponding curtain core. 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.

[0075] Furthermore, since the multiple curtain cores 11 are block-shaped structures, the inner cavity of the water distribution box 2 can be divided into multiple water distribution chambers 22. Each water distribution chamber 22 includes multiple first water distribution chambers 22 corresponding to the multiple curtain cores 11, and each first water distribution chamber 22 has multiple water outlets 21 at its lower end. That is, each water distribution chamber 22 supplies water to one curtain core 11, making each curtain core 11 a completely independent water distribution structure. In this case, the multiple first water distribution chambers 22 can receive water from different outlets of a single water pipe 4, or they can receive water through different water pipes 4. This invention does not impose any limitations on this aspect.

[0076] In other embodiments, the water distribution box 2 may have a chamber that can simultaneously cover multiple curtain cores 11, which can also meet the water distribution requirements.

[0077] Furthermore, the evaporative cooling pad assembly 100 may include a bracket 3, which has a frame structure. The bracket 3 is provided with structures for positioning and installing multiple evaporative cooling pads, thereby defining the relative positions of the multiple evaporative cooling pads. The bracket includes a base plate and multiple support ribs. The base plate has multiple through holes to allow water to flow down. The base plate can provide support for the multiple evaporative cooling pads 11. Support ribs are provided between two adjacent evaporative cooling pads. The multiple support members contact the outer walls of the multiple evaporative cooling pads 11, thereby restricting the position of the multiple evaporative cooling pads 11. The water distribution box 2 is fastened to the upper side of the bracket 3.

[0078] This utility model also proposes a humidifier, 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 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.

[0079] Specifically, the humidifier also includes a housing, a fan assembly, and a water tank. The housing 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, and an air outlet is provided on the top of the housing. The inner cavity of the housing forms a ventilation channel. The fan assembly and the evaporative cooling pad assembly 100 are both located inside the housing and within the ventilation channel. The evaporative cooling pad assembly 100 is located below the fan assembly, within the ventilation channel, and corresponds to the area of ​​the housing where the air inlet is located. The water tank is located inside the housing and below the evaporative cooling pad assembly 100. The water tank is used to guide water to the upper end of the evaporative cooling pad assembly 100 through the water supply assembly, and the water tank is used to collect the water flowing down through the evaporative cooling pad assembly 100. The fan assembly is used to drive the airflow from the air inlet to the air outlet. This allows external air to enter the air passage through the air inlet of the housing, through the air inlet channel of each curtain core 1, and then gather in the ventilation channel, finally being discharged from the air outlet of the housing. Specifically, the external airflow enters through the air inlet, passes through the air inlet channel 11b and the air passage channel 11a of the wet curtain assembly, and flows to the air outlet.

[0080] It should be understood that the water conveying component can be set as a water pipe 4, or other structures that can realize water flow transportation. This utility model does not limit this. In this embodiment, the water pipe 4 can be set inside the wet curtain assembly 100 or outside the wet curtain assembly 100. The water in the water pipe 4 is guided to the water distribution box 2. By setting the inlet water flow rate and the outlet water flow rate of the water distribution box 2, the water can be absorbed to a certain volume and cover all the water distribution ports 21 in the water distribution box 2, thereby achieving a multi-directional uniform water distribution effect.

[0081] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using 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.
