Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a water distribution tray, a wet curtain assembly, and an air conditioning device. Background Technology

[0002] In the relevant solutions, for products such as air conditioning units, a water distribution tray is required to evenly distribute water onto the evaporative cooling pad. However, in these solutions, the water distribution tray is poorly designed, resulting in uneven water distribution on the cooling pad.

[0003] Therefore, designing a water distribution plate that can distribute water more evenly has become an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to at least solve the problem of unreasonable water distribution plate design and uneven water distribution in the prior art or related technologies.

[0005] Therefore, the first aspect of the present invention is to provide a water distribution plate.

[0006] A second aspect of the present invention is to provide a wet curtain assembly.

[0007] A third aspect of the present invention is to provide an air conditioning device.

[0008] The fourth aspect of this invention is to provide a water distribution plate.

[0009] To achieve the above objectives, the first aspect of the present invention provides a water distribution plate, comprising: a plate body; a water inlet hole disposed on the plate body; at least two water outlet channels disposed on the plate body, each water outlet channel being distributed along the circumferential direction of the plate body, and the at least two water outlet channels being independently disposed of each other; a plurality of water outlet holes disposed on the plate body and communicating with the plurality of water outlet channels; and at least two diversion channels disposed on the plate body and distributed along the circumferential direction of the plate body, one end of the plurality of diversion channels communicating with the plurality of water outlet channels one-to-one, and the other end of the plurality of diversion channels communicating with the water inlet hole.

[0010] The water distribution tray provided by the technical solution of the present invention can be specifically used in air conditioning devices. Specifically, the water distribution tray can be placed above the wet curtain of the air conditioning device to evenly distribute the water delivered to the wet curtain. Of course, the water distribution tray can also be used in other products that require even water distribution, such as water-cooled fans. This water distribution tray includes a tray body, a water inlet hole, at least two water outlet channels, multiple water outlets, and at least two diversion channels. The water inlet hole is the water inlet structure of the entire tray body, and all water distributed by the water distribution tray originates from the water inlet hole. The at least two diversion channels are connected to the water inlet hole and are used to divert the water from the water inlet hole into multiple branches. The at least two water outlet channels are used to achieve water distribution. To ensure the uniformity of water distribution in the water outlet channels, the at least two water outlet channels are arranged in a circle around the circumference of the tray body. Water from the water inlet hole is transported to the at least two water outlet channels by the at least two diversion channels, and then enters the water outlets through the water outlet channels and is discharged from the water outlets. In this design, at least two drainage channels are independently configured, meaning they are not interconnected and are located in different areas of the basin. Water from the inlet is directly distributed to the corresponding drainage channels by these two channels, meaning the water is directly allocated to different areas of the basin and then drains through the drainage channels in those areas. This arrangement, by first diverting water to each area and then draining it from each area separately, ensures a more even distribution of water across the basin, thus improving the water distribution uniformity of the basin.

[0011] Each diversion channel is arranged along the circumferential direction of the disc body. That is, the diversion channels are not arranged radially.

[0012] The height of the drainage channel and the water distribution channel cannot be too small. If it is too small, the resistance of the water flow inside will be too great, and the drainage speed will be slowed down. Therefore, the height of the drainage channel and the water distribution channel can be greater than 4mm.

[0013] In any of the above embodiments, optionally, the number of water inlet holes is one. This arrangement ensures centralized water supply, thereby simplifying the structure of the water distribution plate.

[0014] In any of the above embodiments, optionally, at least two drainage channels have equal lengths in the circumferential direction of the disc body, and at least two drainage channels are distributed on the first circumferential trajectory of the disc body, while a plurality of drainage holes are distributed at equal intervals on the second circumferential trajectory of the disc body.

[0015] In this embodiment, each drain channel is of equal length and is arranged on the same circumferential trajectory. This ensures that the multiple drain channels are evenly distributed on the disc, thus ensuring uniform drainage in different areas of the disc. Similarly, the drain holes are evenly distributed on the second circumferential trajectory of the disc, further ensuring uniform drainage in different areas of the disc.

[0016] In any of the above embodiments, optionally, at least two drainage channels are distributed on the first circumferential trajectory of the disc body, and there are at least four diversion channels. Along the radial direction of the disc body, some of the at least four diversion channels are located outside the at least two drainage channels, and the other part of the at least four diversion channels are located inside the at least two drainage channels.

[0017] When there are two diversion channels, they can be set on the left and right sides of the tray. When there are four or more diversion channels, some diversion channels can be set near the outer edge of the tray, and others can be set near the inner edge of the tray. This leaves the central area of ​​the tray open for the drainage channels, allowing the drainage channels to be set closer to the radial center of the wet curtain, thus making the water flow more evenly distributed on the wet curtain.

[0018] For example, the number of diversion channels set near the inner edge of the disc body can be one or more, and the number of diversion channels set near the outer edge of the disc body can also be one or more. In this way, each drain channel of the disc body can be divided into smaller parts, so that the water flow uniformity of each drain channel can be better controlled.

[0019] For example, the disc body includes two semi-annular regions, and two diversion channels are provided on the semi-annular regions. The two diversion channels located on the same semi-annular region are arranged at a radial distance from each other along the disc body.

[0020] In this embodiment, the semi-annular area is half of a complete annular area, that is, each semi-annular area corresponds to a 180° area of ​​the disc. Each semi-annular area is provided with two diversion channels, thus forming four diversion channels on the disc, which can divide the water from the water inlet into four flow paths, thereby delivering it to four different drainage channels.

[0021] In one specific embodiment, there are four drainage channels and four diversion channels. Among the two diversion channels located on the same side of the water inlet, one diversion channel is located inside its corresponding drainage channel, and the other diversion channel is located outside its corresponding drainage channel.

[0022] In this embodiment, four diversion channels can be formed on the plate, which can divide the water from the water inlet into four flow paths, thereby delivering it to four different drainage channels.

[0023] In any of the above embodiments, optionally, at least two diversion channels are connected to the water inlet at the end away from the drain channel, and the connection positions of at least two diversion channels and the water inlet are evenly distributed along the circumferential direction of the water inlet.

[0024] In this technical solution, at least two diversion channels and the water inlet are directly connected and interconnected. Furthermore, the inlets of at least two diversion channels are evenly distributed around the water inlet, meaning the interconnected area between the at least two diversion channels and the water inlet is equal. This ensures that the water discharged from the water inlet is evenly distributed into the at least two diversion channels, and then evenly distributed into the at least two drainage channels, thus ensuring uniform water distribution in each drainage channel and guaranteeing the uniformity of water distribution in different areas of the tray.

[0025] In any of the above embodiments, optionally, at least two drainage channels are arranged axially symmetrically on the disc body, and / or at least two diversion channels are arranged axially symmetrically on the disc body.

[0026] In this technical solution, the drain channel and at least two diversion channels on the tray can be symmetrically arranged about the same axis of symmetry, or each can be symmetrically arranged about its own axis of symmetry. This arrangement allows the channels on the tray to be set into two symmetrical halves, so that the water fed into the tray can be divided into two independent portions first, and then it is only necessary to ensure that each portion of water can be evenly distributed subsequently. This solution, by dividing the channels on the tray into two portions first, reduces the length of each channel compared to treating the channels on the tray as a whole, thus making it easier to control the uniformity of the distribution later.

[0027] Furthermore, at least two drainage channels are arranged symmetrically about the axis of symmetry of the water inlet on the disc body, and / or at least two diversion channels are arranged symmetrically about the axis of symmetry of the water inlet on the disc body. That is, both at least two drainage channels and at least two diversion channels are arranged symmetrically about the axis of symmetry of the water inlet, which allows the water distribution disc to be set into an axially symmetrical structure. This ensures uniform water distribution and also makes the structure of the disc body simpler and easier to manufacture.

[0028] In any of the above embodiments, optionally, an air passage hole is provided in the middle of the disk body, extending through the disk body along the thickness direction.

[0029] In this embodiment, the center of the disc is a hollow structure running vertically through it, i.e., the disc is an annular disc. This hollow structure forms an air passage, which corresponds to the air passage channel in the center of the evaporative cooling pad. The air humidified by the evaporative cooling pad can enter the air passage through the air passage and then exit from the air passage. The water inlet, at least two water outlet channels, and multiple water outlets are all located between the inner and outer rings of the disc, i.e., the water inlet, at least two water outlet channels, and multiple water outlets are not located within the air passage in the center of the annular disc.

[0030] In any of the above embodiments, optionally, the center lines of the plurality of drain holes and / or water inlets are located on the radial center line of the tray. The center lines of the plurality of drain holes and / or water inlets are arranged corresponding to the radial center position of the evaporative cooling pad.

[0031] In this embodiment, the centerlines of the multiple drain holes and / or water inlets are located on the radial centerline of the tray. This ensures the drain holes are relatively centered, allowing water to fall to the central area at the top of the evaporative cooling pad and then flow to both sides. This ensures that water in the distribution tray falls directly to the center of the evaporative cooling pad and then flows outwards, resulting in a more even water distribution. Alternatively, in other embodiments, the drain holes can be positioned corresponding to the edges of the evaporative cooling pad.

[0032] In any of the above embodiments, optionally, a partition rib is provided in the water inlet hole, the partition rib divides the water inlet hole into multiple independently provided water inlet channels, the multiple water inlet channels are distributed along the circumferential direction of the water inlet hole, and the multiple water inlet channels are connected one-to-one with the ends of the multiple diversion channels away from the drainage channels.

[0033] In this embodiment, a dividing rib is provided inside the water inlet hole. The dividing rib divides the water inlet hole into multiple water channels in advance, and each water channel is connected to an independently configured diversion channel. This arrangement ensures that the water in the water inlet hole is pre-divided into multiple parts, thus ensuring that the water in the water inlet hole is evenly distributed to each diversion channel, regardless of whether the water distribution plate is placed horizontally or at an angle. Taking the water distribution plate used in an air conditioning device as an example, when the air conditioning device is placed on an inclined surface, although the entire evaporative cooling pad assembly of the air conditioning device is also inclined, the water inlet hole is vertical relative to the evaporative cooling pad assembly. The water flow inside the water inlet hole is always full, and the dividing rib in the water inlet hole is perpendicular to the inner hole of the water inlet hole. Since the two are always in a perpendicular state, the water flow is always evenly distributed.

[0034] The partition ribs and the disc body are either an integral structure or molded as a single piece. Of course, the partition ribs and the disc body can also be manufactured separately.

[0035] In any of the above technical solutions, optionally, the dividing rib is a cross-shaped dividing rib, so that the water inlet hole can be divided into 4 water inlet channels.

[0036] In any of the above embodiments, optionally, the drainage channel includes a connecting port, a first drainage sub-channel, and a second drainage sub-channel. The first drainage sub-channel extends from the connecting port along the circumference of the disc in a first direction, and the second drainage sub-channel extends from the connecting port along the circumference of the disc in a second direction. The first drainage sub-channel and the second drainage sub-channel are symmetrically distributed about the connecting line passing through the connecting port and the center of the disc, or the paths of water flow from the connecting port to the endpoints of the first drainage sub-channel and the second drainage sub-channel are equal.

[0037] In this embodiment, the first and second directions are opposite, one clockwise and the other counterclockwise. The drainage channel is divided into a first drainage sub-channel and a second drainage sub-channel from the connecting port. Both the first and second drainage sub-channels extend circumferentially from the connecting port, but in opposite directions, such as one clockwise and the other counterclockwise. The center of the disc is the disc center. The connecting port is symmetrically arranged about the first connecting line passing through the disc center, and the first and second drainage sub-channels are symmetrically distributed about the first connecting line. This ensures that the structures of the multiple drainage sub-channels are consistent, resulting in more uniform drainage. By dividing each drainage channel into two symmetrically arranged drainage sub-channels, the path of water flow after diversion is shortened, thus allowing for better control of the drainage uniformity of the entire drainage channel and improving the drainage uniformity of the water distribution disc.

[0038] In any of the above embodiments, optionally, a blocking wall is provided at the end of the first and second drainage sub-channels away from the connection port, and the end of the first and second drainage sub-channels away from the connection port is closed by the blocking wall.

[0039] In this embodiment, the end of each drainage sub-channel is closed, so that each drainage channel is set independently. This can prevent water from flowing together between different drainage channels and interfering with each other, thus avoiding uneven water distribution.

[0040] In any of the above embodiments, optionally, the water distribution plate further includes: a diversion structure, which is disposed in the communication port, and the diversion structure includes a first diversion surface and a second diversion surface. The first diversion surface is used to divert water from the communication port to the first drainage sub-channel, and the second diversion surface is used to divert water from the diversion channel to the second drainage sub-channel.

[0041] In these technical solutions, the two adjacent ends of the two drainage sub-channels are connected by a connecting port. A diversion structure is installed at the connecting port, with a first diversion surface and a second diversion surface on each side. These surfaces divert water from the connecting port into the different drainage sub-channels. This diversion structure ensures that water in the diversion channel is evenly distributed between the two drainage sub-channels, thus guaranteeing uniform water distribution within the drainage system.

[0042] In any of the above embodiments, optionally, the outlet end of the diversion channel is connected to and connected to the communication port.

[0043] In this embodiment, the diversion channel directly delivers water to the connecting port, meaning there is a direct connection between the diversion channel and the connecting port. Of course, an additional connection structure can also be provided between the diversion channel and the connecting port to achieve an indirect connection.

[0044] In any of the above embodiments, optionally, each drainage channel is provided with at least two drainage holes, the at least two drainage holes including: a first drainage hole, which is located outside the drainage channel and is connected to the drainage channel through a connecting channel; and a second drainage hole, which is located inside the drainage channel and is connected to the drainage channel.

[0045] In these technical solutions, the structure of the drain holes can be configured as needed. However, for the same drainage channel, the water flow will differ depending on the location of the drain holes. For example, the upstream drain hole may contact the water flow first, followed by the downstream drain hole. To ensure uniform drainage between the upstream and downstream drain holes, some drain holes can be designated as secondary drain holes within the drainage channel. Water flowing through these secondary drain holes can directly exit through them. Alternatively, some drain holes can be designated as primary drain holes, located on one side of the drainage channel and connected to it via a connecting channel. During the design phase, the opening size of the connecting channel can be adjusted based on the actual location of the primary drain hole to regulate its flow rate and ensure uniform drainage between the primary and secondary drain holes.

[0046] In any of the above embodiments, optionally, a ring-shaped baffle is provided around the first drain hole, and a notch is provided on the ring-shaped baffle to connect the inner side of the ring-shaped baffle with the drain channel. At least a portion of the ring-shaped baffle is used to form the drain channel, and the notch is provided on the part of the ring-shaped baffle that forms the drain channel.

[0047] For example, an annular baffle can be provided around the first drain hole to enclose it, and then a notch can be made on the annular baffle to allow water in the drain channel to enter the first drain hole.

[0048] Furthermore, at least a portion of the annular retaining rib is used to form a drainage channel, with a notch located at the part of the annular retaining rib that forms the drainage channel. This arrangement makes the first drainage hole and the drainage channel relatively close, thereby making the structure of the water distribution plate more compact.

[0049] In any of the above embodiments, optionally, the first drain hole is located on the upstream side of the drain channel, and the second drain hole is located on the downstream side of the drain channel.

[0050] In these technical solutions, the first drain hole can be located on the upstream side, and by reasonably configuring the structure of the connecting channel, the water flow of the first drain hole and the second drain hole can be made consistent, thereby ensuring the uniformity of water distribution in the drainage channel. When the drainage channel has multiple branches, the same drainage channel can have multiple upstream sides and multiple downstream sides.

[0051] In any of the above embodiments, optionally, the drainage channel includes at least one bend section, the bend section being provided corresponding to the first drainage hole, and the bend section enabling the water flow to be deflected towards the direction of the first drainage hole.

[0052] In this embodiment, since the first drain hole is located on the side of the drain channel and the second drain hole is located inside the drain channel, it is logical that the second drain hole would drain water more easily. To increase the flow rate of the first drain hole, two reverse bends can be designed at both ends of the first drain hole to form a bend section. The first bend is angled towards the first drain hole, causing the water flow to be subjected to an inward force when turning, thus directing the water flow towards the first drain hole. When the water flow passes through the second bend, it encounters resistance again, generating a reverse force that causes some water to also flow into the first drain hole. This bend design ensures that the water flow from the first drain hole does not differ significantly from that from the second drain hole, thereby ensuring the uniformity of water flow between the different drain holes.

[0053] In any of the above embodiments, optionally, the drainage channel includes at least two drainage sub-channels, each drainage sub-channel being provided with a first drainage hole and a second drainage hole. When the drainage channel is divided into at least two drainage sub-channels, each drainage sub-channel is provided with a first drainage hole and a second drainage hole, the first drainage hole being located on the upstream side of the drainage sub-channel and the second drainage hole being located on the downstream side of the drainage sub-channel. Furthermore, each drainage sub-channel is provided with a bend.

[0054] In any of the above embodiments, optionally, an overflow port is provided at the end of the drain channel, the overflow port is higher than the bottom wall of the drain channel, and the water distribution plate further includes: an overflow channel, which is provided on the plate body and distributed along the circumferential direction of the plate body, and multiple overflow holes are provided in the overflow channel; wherein, the overflow channel and the diversion channel are located on the same circumferential trajectory.

[0055] In these technical solutions, when the water in the drain channel cannot be drained in time, the excess water can be discharged into the overflow channel through the overflow port. The water flowing out of the overflow channel through the overflow hole flows directly onto the wet curtain or similar device below the water distribution plate. This ensures full utilization of the water flow and also guarantees that the water flow inside the plate forms a circulation path, preventing the water distribution plate from becoming too sealed and forming internal air bubbles that would hinder normal water flow. This maintains the air pressure balance inside the water distribution plate.

[0056] The overflow outlet is higher than the bottom wall of the sewer channel, so that the water can only overflow from the overflow outlet when the water level in the sewer channel reaches a certain height. When the water level in the sewer channel is low, the water can only be discharged from the drain hole.

[0057] In any of the above embodiments, optionally, the disc body includes an outer bottom wall surface, and the outer bottom wall surface is provided with a groove at the part corresponding to the drain channel, so that water from the drain hole can flow out through the groove.

[0058] In this embodiment, by setting a groove, a certain gap can be made between the outer bottom wall surface corresponding to the drain channel and the wet curtain, so as to avoid the spunlace fabric inside the wet curtain from clogging the drain hole, affecting the drainage, or even preventing the drainage, thus ensuring the smooth drainage of the drain hole.

[0059] Furthermore, the portion of the outer bottom wall located on both radial sides of the groove is flat. For example, the back of the water distribution tray adopts a structure that is high in the middle and low on both sides, ensuring that both sides are a complete flat surface. This ensures perfect adhesion between the wet curtain and the water distribution tray, and the flat areas on both sides of the water distribution tray are the glue application areas.

[0060] Furthermore, the outer bottom wall surface corresponding to the drainage channel is at least 2mm higher than the top of the wet curtain.

[0061] Furthermore, the disc body includes an outer bottom wall surface, and a ring of drainage ribs is provided on the portion of the outer bottom wall surface corresponding to the drain channel. The drainage ribs enclose a drainage channel that communicates with the drain hole. For example, a flange can be designed at the drain hole position to form drainage ribs. The arrangement of the drainage ribs can prevent water from spreading around the outer bottom wall surface corresponding to the drain channel due to the surface tension and viscosity of the water itself, thus preventing it from affecting the drainage.

[0062] In any of the above embodiments, optionally, the bottom wall of the diversion channel is provided with a slope that gradually rises along the direction of water flow.

[0063] In this embodiment, a slope is designed on the bottom wall of each diversion channel, such as at the end of the diversion channel, to raise the water flow, forming a ramp. This ramp can reduce the positive impact force of the water flow in the diversion channel before diversion, and after being buffered by the slope, the water flow can be diverted more evenly at the connection point.

[0064] In any of the above embodiments, optionally, the disc body includes: a chassis; a top cover, mounted on the chassis to cover the chassis; wherein, an inlet water hole and a outlet water hole are provided on the chassis, and a outlet water channel and a diversion channel are formed by the chassis and the top cover.

[0065] In this embodiment, the tray is enclosed by a chassis and a top cover, thus forming a relatively enclosed water passage and preventing water from being exposed to the air. To form the drainage and diversion channels, grooves can be provided on the inner side of the chassis or top cover, and the enclosure of the chassis and top cover then creates the drainage and diversion channels. Alternatively, grooves can be provided on both the inner sides of the chassis and the top cover simultaneously to form both drainage and diversion channels.

[0066] In any of the above embodiments, optionally, the chassis is provided with one of a positioning post and a positioning hole, and the top cover is provided with the other of a positioning post and a positioning hole. The chassis and the top cover are positioned and installed through the positioning post and the positioning hole. The top cover is provided with a partition rib, and at least a portion of the partition rib is inserted into the drain hole to divide the drain hole into multiple independently configured water inlet channels.

[0067] In this embodiment, the positioning pins and holes work together to achieve precise positioning between the chassis and the top cover, ensuring a more accurate relative position after installation. A dividing rib is provided at the water inlet, dividing the water flow into two branches from the outset, allowing for individual control of each branch. This design, by dividing the water inlet into multiple channels, ensures more even water distribution and guarantees uniform water flow during the water supply process.

[0068] An embodiment of the second aspect of this application provides an evaporative cooling pad assembly, comprising: an evaporative cooling pad; and a water distribution tray provided in any embodiment of the first aspect, the water distribution tray being mounted on top of the evaporative cooling pad.

[0069] The evaporative cooling pad assembly proposed in this application has all the beneficial effects of the water distribution tray provided in any embodiment of the first aspect, since it includes the water distribution tray provided in any embodiment of the first aspect, which will not be repeated here.

[0070] In any of the above embodiments, optionally, an air passage hole penetrating the disk along the thickness direction is provided in the middle of the disk body, the evaporative cooling pad is arranged in a ring and surrounds the air passage channel, and the air passage hole is connected to the air passage channel. Multiple drain holes are arranged at the radial center position of the evaporative cooling pad.

[0071] In this embodiment, the center of the tray is a hollow structure running vertically through it, forming air passages. These air passages correspond to the air passage channels in the center of the evaporative cooling pad. Humidified air passing through the evaporative cooling pad enters through these air passages and then exits through the air passages. Multiple drain holes are positioned radially at the center of the evaporative cooling pad, ensuring they are relatively centered. This allows water to fall to the central area at the top of the evaporative cooling pad and then flow to both sides, resulting in more even wetting. Alternatively, in other designs, the drain holes can be positioned along the edges of the evaporative cooling pad.

[0072] An embodiment of the third aspect of this application provides an air conditioning device including the evaporative cooling pad assembly provided in any embodiment of the second aspect.

[0073] The air conditioning device proposed according to the embodiments of this application has all the beneficial effects of the wet curtain assembly provided in any embodiment of the second aspect since it includes the wet curtain assembly provided in any embodiment of the second aspect, which will not be repeated here.

[0074] Specifically, the air conditioning device can be a humidifier, an air purifier with humidification function, or a water-cooled fan.

[0075] In any of the above embodiments, optionally, the air conditioning device is a humidifier, which further includes: a water tank; a wet curtain bracket installed in the water tank, with the wet curtain assembly installed on the wet curtain bracket; a water inlet pipe installed on the wet curtain bracket and extending to the water distribution plate, communicating with the water inlet hole; and a water pump located in the water tank and communicating with the inlet of the water inlet pipe.

[0076] In this embodiment, the air conditioning device can specifically be a humidifier. This humidifier includes the aforementioned evaporative cooling pad assembly, which enables even distribution of water on the evaporative cooling pad, thereby ensuring uniform wetting of the pad. Furthermore, the humidifier also includes a water tank, a water inlet pipe, and a water pump. Water from the water tank is pumped through the water pump and the water inlet pipe to the water inlet of the water distribution plate, and water from the water inlet flows through the water outlet to the evaporative cooling pad, thus supplying water to the evaporative cooling pad.

[0077] Furthermore, the evaporative cooling pad support also includes a lower cover installed at the bottom of the evaporative cooling pad, the lower cover having a water inlet channel connected to the water supply pipe; and a sealing element installed inside the water inlet channel to seal the gap between the water inlet channel and the water supply pipe of the air conditioning unit.

[0078] In this technical solution, the lower cover supports the installation of the evaporative cooling pad and connects the water supply pipe and the water tank via the water inlet channel. A seal is used to seal the gap between the water inlet channel and the water supply pipe of the air conditioning unit, preventing leakage from the evaporative cooling pad.

[0079] The sealing component is made of silicone.

[0080] Air conditioning devices can specifically be humidifiers, air purifiers with humidification functions, or water-cooled fans.

[0081] In this embodiment, the humidifier is designed in the following way to ensure that the wet curtain can be fully wetted:

[0082] 1. Dividing ribs are installed at the water inlet. This design allows the water in the water inlet to be pre-divided into multiple parts, ensuring that the water in the water inlet is evenly distributed to each diversion channel, whether the water distribution plate is placed horizontally or at an angle.

[0083] 2. The basin is equipped with at least two diversion channels and at least two drainage channels. In this structure, water from the inlet is directly distributed to different areas of the basin by at least two diversion channels, and then drains from the drainage channels of each area. This design, by first diverting water to each area and then draining it from each area separately, ensures a more even distribution of water across the basin, thus improving the water distribution uniformity of the basin.

[0084] 3. Each drainage channel is divided into two sub-drainage channels. Dividing each drainage channel into two symmetrically arranged sub-drainage channels can shorten the path of water flow after diversion, thereby making it easier to control the uniformity of drainage in the entire drainage channel, which can improve the uniformity of drainage in the water distribution plate.

[0085] This type of humidifier features a carefully designed structure at every stage, from water inlet to distribution and drainage. The design of the water inlet ensures uniform water supply; multiple distribution channels and drainage channels distribute water to different areas, enabling zoned water control and ensuring even drainage across the tray; and dividing the drainage channel into two sub-channels shortens the water flow path, further enhancing drainage uniformity. Through this triple structural design, the humidifier effectively ensures uniform water flow at each stage of the evaporative cooling pad assembly, resulting in a perfectly even distribution of water on the pad.

[0086] An embodiment of the fourth aspect of this application provides a water distribution tray, comprising: a tray body; a water inlet hole disposed on the tray body; a diversion channel disposed on the tray body and communicating with the water inlet hole; a water outlet channel disposed on the tray body; and a plurality of water outlet holes disposed within the water outlet channel; wherein the water outlet channel includes a connecting opening, a first water outlet sub-channel, and a second water outlet sub-channel, the first water outlet sub-channel extending from the connecting opening along the circumference of the tray body in a first direction, and the second water outlet sub-channel extending from the connecting opening along the circumference of the tray body in a second direction, and the first water outlet sub-channel and the second water outlet sub-channel are symmetrically distributed about a connecting line passing through the connecting opening and the center of the tray body, or the paths of water flow from the connecting opening to the endpoints of the first water outlet sub-channel and the second water outlet sub-channel are equal. This includes the evaporative cooling pad assembly provided in any embodiment of the second aspect.

[0087] The water distribution tray proposed in the embodiments of this application can be specifically used in air conditioning devices. Specifically, the water distribution tray can be placed above the evaporative cooling pad of the air conditioning device to evenly distribute the water delivered to the evaporative cooling pad. Of course, the water distribution tray can also be used in other products that require even water distribution, such as water-cooled fans. The water distribution tray provided in this application includes a tray body, a water inlet hole, a diversion channel, a drain channel, and multiple drain holes. The water inlet hole is the water inlet structure of the entire tray body, and all water distributed by the water distribution tray originates from the water inlet hole. The diversion channel is connected to the water inlet hole and is used to transport water from the water inlet hole to the drain channel. Simultaneously, the drain channel is divided into a first drain sub-channel and a second drain sub-channel from the connection opening. Both the first and second drain sub-channels extend circumferentially from the connection opening, but their extending directions are opposite, for example, one extends clockwise and the other extends counterclockwise. The center of the disc is its core. The connecting ports are symmetrically arranged about the first connecting line passing through the core. The first and second drainage sub-channels are also symmetrically distributed about the first connecting line. This ensures that the structures of the multiple drainage sub-channels are consistent, resulting in more uniform drainage. Alternatively, the paths from the connecting port to the end point of the first and second drainage sub-channels are equal, meaning the distance traveled by the water from the connecting port to the end point of each drainage sub-channel is the same. This ensures that the multiple drainage sub-channels are basically symmetrically arranged, further enhancing the uniformity of drainage. This scheme, by dividing each drainage channel into two symmetrically arranged drainage sub-channels, shortens the path of water flow after diversion, thus allowing for better control of the drainage uniformity of the entire drainage system and improving the overall drainage uniformity of the distribution disc.

[0088] In any of the above embodiments, optionally, there are at least two drainage channels, which are symmetrically distributed on the same circumferential direction of the disc; there are at least two diversion channels, which are connected one-to-one with the connection ports of the at least two drainage channels.

[0089] In this embodiment, at least two drainage channels are independently configured, meaning they are not interconnected and are located in different areas of the basin. Water from the inlet holes can be directly transported to the corresponding drainage channels by the at least two diversion channels; that is, water from the inlet holes is directly distributed to different areas of the basin by the at least two diversion channels, and then drains from the drainage channels of those different areas. This configuration, by first diverting water to each area and then draining it from each area separately, ensures that the water is distributed more evenly across the different areas of the basin, thus improving the water distribution uniformity of the water distribution basin.

[0090] Simultaneously, at least two drainage channels are symmetrically arranged about the same axis of symmetry. This allows the drainage channels on the tray to be configured as two symmetrical halves. This enables the water entering the tray to be initially divided into two independent portions, and then it is only necessary to ensure that each portion of water is subsequently distributed evenly. This approach, by dividing the drainage channels and diversion channels on the tray into two parts, reduces the length of each drainage channel compared to treating the channels on the tray as a single unit, thus facilitating the uniformity control of subsequent drainage.

[0091] In any of the above embodiments, optionally, the diversion channel includes a first diversion channel and a second diversion channel, the first diversion channel and the second diversion channel are equidistant from the water inlet to their corresponding connecting ports (i.e., the water flows the same distance), or the first diversion channel and the second diversion channel are symmetrically arranged on both sides of the water inlet.

[0092] In this embodiment, the first and second diversion channels are symmetrically arranged about the water inlet, so that part or all of the water in the water inlet can be divided into two equal parts and sent to different drainage channels. For example, there can be only two diversion channels, so that the water in the water inlet can be divided into two parts for separate transportation, and then divided into two branches in the drainage channel, thus forming four water distribution branches on the plate.

[0093] In any of the above embodiments, optionally, the diversion channel includes a third diversion channel and a fourth diversion channel, the second distance from the water inlet to the corresponding connecting port of the third diversion channel and the fourth diversion channel is equal, or the third diversion channel and the fourth diversion channel are symmetrically arranged on both sides of the water inlet; the first diversion channel and the second diversion channel are arranged on the radial side of the disc body, and the third diversion channel and the fourth diversion channel are arranged on the radial side of the disc body; the first distance is greater than or less than the second distance.

[0094] In this embodiment, the disc body is provided with four diversion channels, which are symmetrically arranged about the water inlet. This ensures that the diversion channels on each half of the disc body are identical, thus dividing the water flow in half along the central axis of the disc body. In this scheme, the water flow on the disc body is first divided into four branches, and then each branch is further divided into two branches at the drain channel, thus forming eight branches on the disc body. This scheme divides the water flow in the diversion disc into eight equal parts, essentially dividing the entire disc body into eight areas for drainage. This results in shorter water flow paths in each area, leading to better control over the subsequent uniformity of the water flow and thus better ensuring the uniformity of drainage in the diversion disc.

[0095] Since the water inlet is fixed, and the connecting openings are located in different positions, the length of the diversion channel on each half of the plate is inconsistent.

[0096] In any of the above embodiments, optionally, the first diversion channel and the second diversion channel are disposed near the inner side of the disk body along the radial direction, and the third diversion channel and the fourth diversion channel are disposed near the outer side of the disk body along the radial direction; the first distance is greater than the second distance.

[0097] In this embodiment, the four diversion channels are arranged symmetrically in pairs. To facilitate the placement of the drainage channels at the radial center of the wet curtain, the first and second diversion channels can be positioned near the inner edge of the tray, while the third and fourth diversion channels can be positioned near the outer edge of the tray. This allows the central area of ​​the tray to be reserved for the drainage channels.

[0098] In this design, the water distribution channels are evenly distributed across the plate, resulting in varying positions of the different connecting ports. This leads to unequal lengths of the distribution channels (the distance water travels from the inlet hole to the corresponding connecting port). In this application, the distribution channels on the inner edge are longer, while those on the outer edge are shorter. This means the inner edge channels correspond to connecting ports at greater distances, while the outer edge channels correspond to connecting ports at closer distances. This arrangement minimizes the difference between the first and second distances because the outer edge has a longer perimeter than the inner edge. Therefore, the inner edge channels, corresponding to more distant connecting ports, result in a shorter overall path.

[0099] The structure of the water distribution plate proposed in the fourth aspect of this application, the specific structure of the diversion channel, the structure of the drainage channel, and the specific structure of the plate body can be set with reference to the water distribution plate proposed in the first aspect of this application, and will not be repeated here.

[0112] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0113] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0114] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0115] The following reference Figures 1 to 8 The present application describes the water distribution tray 100, the wet curtain assembly 200, and the air conditioning device 300 provided in the embodiments of this application.

[0116] like Figures 1 to 8 As shown, an embodiment of the first aspect of the present invention provides a water distribution plate 100, including a plate body 1, a water inlet hole 2, at least two drainage channels 3, a plurality of drainage holes 4, and at least two diversion channels 5. The water inlet hole 2 is disposed on the plate body 1. At least two drainage channels 3 are disposed on the plate body 1, each drainage channel 3 being distributed along the circumferential direction of the plate body 1, and the at least two drainage channels 3 are independently disposed. The plurality of drainage holes 4 are disposed on the plate body 1 and communicate with the plurality of drainage channels 3. At least two diversion channels 5 are disposed on the plate body 1, distributed along the circumferential direction of the plate body 1, with one end of each diversion channel 5 corresponding to and communicating with one of the plurality of drainage channels 3, and the other end of each diversion channel 5 communicating with the water inlet hole 2.

[0117] The water distribution tray 100 provided according to an embodiment of the present invention can be specifically used in an air conditioning device 300. Specifically, the water distribution tray 100 can be placed above the evaporative cooling pad 210 of the air conditioning device 300 to evenly distribute the water delivered to the evaporative cooling pad 210. Of course, the water distribution tray 100 can also be used in other products that require even water distribution, such as water-cooled fans. This water distribution tray 100 includes a tray body 1, a water inlet hole 2, at least two water outlet channels 3, multiple water outlet holes 4, and at least two diversion channels 5. Among them, the water inlet hole 2 is the water inlet structure of the entire tray body 1, and the water that needs to be distributed by the water distribution tray 100 comes from the water inlet hole 2. The at least two diversion channels 5 are connected to the water inlet hole 2 and are used to divert the water from the water inlet hole 2 into multiple branches. The at least two water outlet channels 3 are used to realize water distribution. To ensure uniform water distribution in the drainage channels 3, at least two drainage channels 3 are arranged in a circle around the circumference of the basin 1. Water from the inlet holes 2 is transported to the at least two drainage channels 3 by at least two diversion channels 5, and then enters the drainage holes 4 from the drainage channels 3 and is discharged from the drainage holes 4. In this scheme, the at least two drainage channels 3 are independently set, that is, the at least two drainage channels 3 are not connected to each other and are located in different areas of the basin 1. Water from the inlet holes 2 can be directly transported to the corresponding drainage channels 3 by the at least two diversion channels 5, that is, the water from the inlet holes 2 is directly distributed to different areas of the basin 1 by the at least two diversion channels 5, and then drains from the drainage channels 3 of the different areas. This arrangement, by first diverting the water to each area and then draining from each area separately, makes the water distribution in different areas of the basin 1 more uniform, thus making the drainage in different areas of the basin 1 more uniform, thereby improving the water distribution uniformity of the water distribution basin 100.

[0118] Each diversion channel 5 is arranged along the circumferential direction of the disk body 1. That is, the diversion channel 5 is not arranged radially.

[0119] The height of the drainage channel 3 and the water distribution channel cannot be too small. If it is too small, the resistance of the water flow inside will be too great, and the drainage speed will be slowed down. Therefore, the height of the drainage channel 3 and the water distribution channel can be greater than 4mm.

[0120] in, Figure 1 , Figure 7 and Figure 8 The arrows in the diagram indicate the water flow path.

[0121] In any of the above embodiments, optionally, as Figure 1 , Figure 7 and Figure 8 As shown, there is only one water inlet hole 2. This arrangement ensures centralized water supply, thus simplifying the structure of the water distribution plate 100.

[0122] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, at least two drainage channels 3 have equal lengths in the circumferential direction of the disc body 1, and at least two drainage channels 3 are distributed on the first circumferential trajectory of the disc body 1, while multiple drainage holes 4 are distributed at equal intervals on the second circumferential trajectory of the disc body 1.

[0123] In this embodiment, each drain channel 3 is of equal length and is arranged on the same circumferential trajectory. This ensures that the multiple drain channels 3 are evenly distributed on the disc body 1, thus ensuring uniform drainage in different areas of the disc body 1. Similarly, the drain holes 4 are evenly distributed on the second circumferential trajectory of the disc body 1, further ensuring uniform drainage in different areas of the disc body 1.

[0124] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 4 As shown, at least two drainage channels 3 are distributed on the first circumferential trajectory of the disc body 1, and there are at least four diversion channels 5. Along the radial direction of the disc body 1, some of the channels of the at least four diversion channels 5 are located outside the at least two drainage channels 3, and the other channels of the at least four diversion channels 5 are located inside the at least two drainage channels 3.

[0125] When there are two diversion channels 5, they can be set on the left and right sides of the disc body 1. When there are four or more diversion channels 5, some diversion channels 5 can be set close to the outer edge of the disc body 1, and other diversion channels 5 can be set close to the inner edge of the disc body 1. This way, the central area of ​​the disc body 1 can be reserved for setting the drain channel 3. This allows the drain channel 3 to be set closer to the radial center area of ​​the wet curtain 210, so that the water flow can be distributed more evenly on the wet curtain 210.

[0126] For example, the number of diversion channels 5 provided near the inner edge of the disc body 1 can be one or more, and the number of diversion channels 5 provided near the outer edge of the disc body 1 can also be one or more. In this way, each drain channel 3 of the disc body 1 can be divided into smaller parts, so that the water flow uniformity of each drain channel 3 can be better controlled.

[0127] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the disc body 1 includes two semi-annular regions, and two diversion channels 5 are provided on the semi-annular regions. The two diversion channels 5 located on the same semi-annular region are arranged at radial intervals along the disc body 1.

[0128] In this embodiment, the semi-annular area is half of a complete annular area, that is, each semi-annular area corresponds to 180° of the plate body 1. Each semi-annular area is provided with two diversion channels 5, so that four diversion channels 5 can be formed on the plate body 1, which can divide the water in the water inlet 2 into four flow paths, thereby delivering it to four different drainage channels 3.

[0129] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, there are four drainage channels 3 and four diversion channels 5. Among the two diversion channels 5 located on the same side of the water inlet 2, one diversion channel 5 is located inside its corresponding drainage channel 3, and the other diversion channel 5 is located outside its corresponding drainage channel 3.

[0130] In this embodiment, four diversion channels 5 (i.e., first diversion channel 5a, second diversion channel 5b, third diversion channel 5c, and fourth diversion channel 5d) can be formed on the plate 1, which can divide the water in the water inlet 2 into four flow paths, thereby delivering it to four different drainage channels 3.

[0131] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 4 As shown, at least two diversion channels 5 are connected to the water inlet 2 at their ends away from the drain channel 3, and the connection positions of at least two diversion channels 5 and the water inlet 2 are evenly distributed along the circumferential direction of the water inlet 2.

[0132] In this embodiment, at least two diversion channels 5 and the water inlet 2 are directly connected and communicate with each other. Furthermore, the inlets of the at least two diversion channels 5 are evenly distributed around the water inlet 2, meaning that the communication area between the at least two diversion channels 5 and the water inlet 2 is equal. This ensures that the water discharged from the water inlet 2 is evenly distributed into the at least two diversion channels 5, and then evenly distributed into the at least two drainage channels 3. This ensures that the water in each drainage channel 3 is uniform, thereby guaranteeing the uniformity of water distribution in different areas of the plate 1.

[0133] In any of the above embodiments, optionally, as Figure 4 and Figure 8 As shown, at least two drainage channels 3 are arranged symmetrically on the disc body 1, and / or at least two diversion channels 5 are arranged symmetrically on the disc body 1.

[0134] In this embodiment, the drain channel 3 and at least two diversion channels 5 on the tray 1 can be symmetrically arranged about the same axis of symmetry, or each can be symmetrically arranged about its own axis of symmetry. This arrangement allows the channels on the tray 1 to be set into two symmetrical halves, so that the water fed into the tray 1 can be divided into two independent portions first, and then it is only necessary to ensure that each portion of water can be evenly distributed subsequently. This approach, which divides the channels on the tray 1 into two portions first, reduces the length of each portion of the channel compared to treating the channels on the tray 1 as a whole, thus making it easier to control the uniformity of the distribution later.

[0135] Furthermore, at least two drainage channels 3 are on the plate body 1 about the axis of symmetry of the water inlet hole 2 (specifically, they can be...). Figure 3 , Figure 4 The straight line L1 or Figure 7 , Figure 8 The straight line L3 in the middle is arranged symmetrically about the axis of symmetry of the water inlet 2 on the disc body 1, and / or at least two diversion channels 5 are arranged symmetrically about the axis of symmetry of the water inlet 2. Figure 4 The straight line L1 in the middle is arranged symmetrically. That is, at least two drainage channels 3 and at least two diversion channels 5 are arranged symmetrically about the axis of symmetry of the water inlet 2. In this way, the water distribution plate 100 can be set as an axially symmetrical structure, which can ensure the uniformity of water distribution and make the structure of the plate body 1 simpler and easier to process.

[0136] In any of the above embodiments, optionally, as Figure 1 and Figure 5 As shown, a ventilation hole 10 is provided in the middle of the disc body 1, which extends through the disc body 1 along the thickness direction of the disc body 1.

[0137] In this embodiment, the center of the disc 1 is a hollow structure extending vertically, i.e., the disc 1 is an annular disc. This hollow structure forms an air passage 10, which corresponds to the air passage channel 2102 in the center of the evaporative cooling pad 210. The air humidified by the evaporative cooling pad 210 can enter the air passage 10 through the air passage 2102 and then exit from the air passage 10. The water inlet 2, at least two water outlet channels 3, and multiple water outlets 4 are all located between the inner and outer rings of the disc 1, i.e., the water inlet 2, at least two water outlet channels 3, and multiple water outlets 4 are not located within the air passage 10 in the center of the annular disc.

[0138] In any of the above embodiments, optionally, as Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, the center lines of the multiple drain holes 4 and / or water inlets 2 are located on the radial center line of the disc body 1. The center lines of the multiple drain holes 4 and / or water inlets 2 are set at the radial center position of the wet curtain 210.

[0139] In this embodiment, the center lines of the multiple drain holes 4 and / or water inlets 2 are located on the radial center line of the disc body 1. This ensures that the drain holes 4 are relatively centered, allowing water in the drain holes 4 to fall into the central area of ​​the top of the evaporative cooling pad 210 and then flow to both sides of the evaporative cooling pad 210. This ensures that the water in the water distribution disc 100 falls directly into the middle of the evaporative cooling pad 210 and then flows from the middle of the evaporative cooling pad 210 to both sides, thus making the water distribution on the evaporative cooling pad 210 more uniform. Of course, in other embodiments, the drain holes 4 can also be arranged corresponding to the edges of the evaporative cooling pad 210.

[0140] In any of the above embodiments, optionally, as Figure 1 and Figure 4 As shown, a partition rib 144 is provided inside the water inlet hole 2. The partition rib 144 divides the water inlet hole 2 into multiple independently set water inlet channels. The multiple water inlet channels are distributed along the circumferential direction of the water inlet hole 2. The multiple water inlet channels are connected to the ends of the multiple diversion channels 5 away from the drain channel 3.

[0141] In this embodiment, a dividing rib 144 is provided inside the water inlet hole 2. The dividing rib 144 can pre-divide the water inlet hole 2 into multiple water channels, and each water channel is connected to an independently provided diversion channel 5. This arrangement allows the water in the water inlet hole 2 to be pre-divided into multiple parts, thus ensuring that the water in the water inlet hole 2 can be evenly distributed to each diversion channel 5, whether the water distribution plate 100 is placed horizontally or inclined. Taking the water distribution plate 100 used in the air conditioning device 300 as an example, when the air conditioning device 300 is placed on an inclined surface, although the wet curtain assembly 200 of the air conditioning device 300 is also inclined, the water inlet hole 2 is vertical relative to the wet curtain assembly 200, and the water flow inside the water inlet hole 2 is always full. The dividing rib 144 in the water inlet hole 2 is perpendicular to the inner hole of the water inlet hole 2, and the two are always in a perpendicular state, so the water flow can always be evenly distributed.

[0142] The partition rib 144 and the disc body 1 are either an integral structure or integrally formed. Of course, the partition rib 144 and the disc body 1 can also be processed and formed separately.

[0143] In any of the above embodiments, optionally, the dividing rib 144 is a cross-shaped dividing rib, so that the water inlet hole 2 can be divided into 4 water inlet channels.

[0144] In any of the above embodiments, optionally, as Figure 1 and Figure 7As shown, the drainage channel 3 includes a connecting port 30, a first drainage sub-channel 32, and a second drainage sub-channel 34. The first drainage sub-channel 32 extends from the connecting port 30 along the circumference of the disc 1 in a first direction, and the second drainage sub-channel 34 extends from the connecting port 30 along the circumference of the disc 1 in a second direction. The first drainage sub-channel 32 and the second drainage sub-channel 34 are symmetrically distributed about the connecting line passing through the center of the connecting port 30 and the disc 1, or the paths of water flow from the connecting port 30 to the endpoints of the first drainage sub-channel 32 and the second drainage sub-channel 34 are equal.

[0145] In this embodiment, the first direction and the second direction are opposite, one is clockwise and the other is counterclockwise. The drain channel 3 is divided into a first drain sub-channel 32 and a second drain sub-channel 34 from the connecting port 30. Both the first drain sub-channel 32 and the second drain sub-channel 34 extend circumferentially from the connecting port 30, but their extending directions are opposite, for example, one extends clockwise and the other extends counterclockwise. The center of the disc body 1 is the disc center of the disc body 1 (specifically, as shown in the figure). Figure 3 and Figure 4 (Point O in the diagram), wherein the connecting port 30 is symmetrically arranged about the first connecting line passing through the center of the basin, and the first drainage sub-channel 32 and the second drainage sub-channel 34 are symmetrically distributed about the first connecting line. This makes the structure of the multiple drainage sub-channels consistent, thereby making the drainage of the multiple drainage sub-channels more uniform. By dividing each drainage channel 3 into two symmetrically arranged drainage sub-channels, the path of water flow after diversion is shortened, thereby making the drainage uniformity of the entire drainage channel 3 better controlled, thus improving the drainage uniformity of the water distribution basin 100.

[0146] In any of the above embodiments, optionally, as Figure 1 and Figure 7 As shown, a baffle wall 6 is provided at the end of the first drainage sub-channel 32 and the second drainage sub-channel 34 away from the connecting port 30, and the end of the first drainage sub-channel 32 and the second drainage sub-channel 34 away from the connecting port 30 is closed by the baffle wall 6.

[0147] In this embodiment, the end of each drainage sub-channel is closed, so that each drainage channel 3 is set independently. This can prevent water from flowing together between different drainage channels 3 and interfering with each other, thus avoiding uneven water distribution.

[0148] In any of the above embodiments, optionally, as Figure 1 and Figure 7As shown, the water distribution plate 100 also includes a diversion structure 39, which is disposed in the connecting port 30. The diversion structure 39 includes a first diversion surface 392 and a second diversion surface 394. The first diversion surface 392 is used to divert water from the connecting port 30 to the first drain sub-channel 32, and the second diversion surface 394 is used to divert water from the diversion channel 5 to the second drain sub-channel 34.

[0149] In these embodiments, the two adjacent ends of the two drainage sub-channels are connected to each other via a connecting port 30. A diversion structure 39 is provided at the connecting port 30, with a guide surface on each side of the diversion structure 39, namely a first guide surface 392 and a second guide surface 394. Water in the connecting port 30 can be diverted to different drainage sub-channels through the first guide surface 392 and the second guide surface 394. The diversion structure 39 ensures that water in the diversion channel 5 is evenly distributed between the two drainage sub-channels, thus guaranteeing the uniformity of water distribution in the drainage channel 3.

[0150] in, Figure 7 A split structure, such as 39, can also be set in the middle.

[0151] In any of the above embodiments, optionally, as Figure 1 , Figure 7 and Figure 8 As shown, the outlet end of the diversion channel 5 is connected to and conducts through the connection port 30.

[0152] In this embodiment, the diversion channel 5 directly delivers water to the connecting port 30, meaning that the diversion channel 5 and the connecting port 30 are directly connected. Of course, an additional connection structure can also be provided between the diversion channel 5 and the connecting port 30 to achieve an indirect connection between the two.

[0153] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, each drainage channel 3 is provided with at least two drainage holes 4, the at least two drainage holes 4 including: a first drainage hole 42, which is located outside the drainage channel 3 and is connected to the drainage channel 3 through a connecting channel 8; and a second drainage hole 44, which is located inside the drainage channel 3 and is connected to the drainage channel 3.

[0154] In these embodiments, the structure of the drain hole 4 can be configured as needed. However, for the same drainage channel 3, the water flow will differ depending on the position of the drain hole 4. For example, the upstream drain hole 4 may come into contact with the water flow first, while the downstream drain hole 4 may come into contact with the water flow later. To ensure the uniformity of drainage between the upstream and downstream drain holes 4, some drain holes 4 can be configured as second drain holes 44. The second drain holes 44 are located within the drainage channel 3, and the water flow within the drainage channel 3 can directly flow through the second drain holes 44. Alternatively, some drain holes 4 can be configured as first drain holes 42. The first drain holes 42 are located on one side of the drainage channel 3 and are connected to the drainage channel 3 through a connecting channel 8. During the design process, the opening size of the connecting channel 8 can be set according to the actual position of the first drain hole 42 to adjust the flow rate of the first drain hole 42 and ensure the uniformity of drainage between the first drain hole 42 and the second drain hole 44.

[0155] In any of the above embodiments, optionally, as Figure 2 As shown, a ring-shaped baffle 7 is provided around the first drain hole 42. The ring-shaped baffle 7 has a notch 72, which connects the inner side of the ring-shaped baffle 7 with the drain channel 3. At least a part of the ring-shaped baffle 7 is used to form the drain channel 3. The notch 72 is provided at the part of the ring-shaped baffle 7 that forms the drain channel 3.

[0156] For example, such as Figure 2 As shown, a ring-shaped baffle 7 can be set around the first drain hole 42 to enclose the first drain hole 42, and then a notch 72 is opened on the ring-shaped baffle 7 so that water in the drain channel 3 can enter the first drain hole 42.

[0157] Furthermore, at least a portion of the annular baffle 7 is used to form the drainage channel 3, and the notch 72 is provided at the part of the annular baffle 7 that forms the drainage channel 3. This arrangement makes the first drainage hole 42 and the drainage channel 3 relatively close, thereby making the structure of the water distribution plate 100 more compact.

[0158] In any of the above embodiments, optionally, as Figure 1 As shown, the first drain hole 42 is located on the upstream side of the drain channel 3, and the second drain hole 44 is located on the downstream side of the drain channel 3.

[0159] In these embodiments, the first drain hole 42 can be located on the upstream side, and by reasonably configuring the structure of the connecting channel 8, the water flow of the first drain hole 42 and the second drain hole 44 can be made consistent, thereby ensuring the uniformity of water distribution in the drain channel 3. Where the drain channel 3 has multiple branches, the same drain channel 3 can have multiple upstream sides and multiple downstream sides.

[0160] In any of the above embodiments, optionally, as Figure 1 and Figure 2 As shown, the drainage channel 3 includes at least one bend section 38, which is provided corresponding to the first drainage hole 42. The bend section 38 can cause the water flow to flow in the direction of the first drainage hole 42.

[0161] In this embodiment, since the first drain hole 42 is located on the side of the drain channel 3 and the second drain hole 44 is located inside the drain channel 3, it is logical that the second drain hole 44 would drain water more easily. To promote the flow rate of the first drain hole 42, two reverse bends can be designed at both ends of the first drain hole 42 to form bend sections 38. The first bend is biased towards the first drain hole 42, causing the water flow to be subjected to a certain inward force when turning, thus causing the water flow to be biased towards the first drain hole 42. When the water flow passes through the second bend, it again encounters a certain resistance, generating a reverse force, causing some water flow to also reach the first drain hole 42. Through this bend design, the water flow in the first drain hole 42 will not differ significantly from that in the second drain hole 44, thereby ensuring the uniformity of drainage between the different drain holes 4.

[0162] In any of the above embodiments, optionally, as Figure 1 and Figure 7 As shown, drainage channel 3 includes at least two drainage sub-channels. Figure 1 As shown, each drainage sub-channel is equipped with a first drainage hole 42 and a second drainage hole 44. When the drainage channel 3 is divided into at least two drainage sub-channels, each drainage sub-channel is equipped with a first drainage hole 42 and a second drainage hole 44, with the first drainage hole 42 located on the upstream side of the drainage sub-channel and the second drainage hole 44 located on the downstream side of the drainage sub-channel. Furthermore, each drainage sub-channel is equipped with a bend section 38.

[0163] In any of the above embodiments, optionally, as Figure 4 As shown, the end of the drain channel 3 is provided with an overflow port 36, which is higher than the bottom wall of the drain channel 3. The water distribution plate 100 also includes an overflow channel 9, which is provided on the plate body 1 and distributed along the circumferential direction of the plate body 1. Multiple overflow holes 92 are provided in the overflow channel 9. The overflow channel 9 and the diversion channel 5 are located on the same circumferential trajectory.

[0164] In these embodiments, when the water in the drain channel 3 cannot be drained in time, the excess water can be discharged into the overflow channel 9 through the overflow port 36. The water flowing out of the overflow channel 9 through the overflow hole 92 flows directly onto the wet curtain 210 or similar surface below the water distribution plate 100. This ensures full utilization of the water flow and also guarantees that the water flow inside the plate 1 forms a circulation path, preventing the water distribution plate 100 from becoming too sealed, forming internal air bubbles, and thus ensuring the air pressure balance inside the water distribution plate 100.

[0165] The overflow outlet 36 is higher than the bottom wall of the drain channel 3, so that the water in the drain channel 3 can only overflow from the overflow outlet 36 when the water level in the drain channel 3 reaches a certain height. When the water level in the drain channel 3 is low, the water can only be discharged from the drain hole 4.

[0166] In any of the above embodiments, optionally, as Figure 5 As shown, the disc body 1 includes an outer bottom wall 16, and a groove 18 is provided on the outer bottom wall 16 corresponding to the drain channel 3, through which water from the drain hole 4 can flow out.

[0167] In this embodiment, by setting the groove 18, there can be a certain gap between the outer bottom wall 16 corresponding to the drain channel 3 and the wet curtain 210, so as to avoid the spunlace fabric inside the wet curtain 210 from blocking the drain hole 4, affecting the drainage, or even preventing the drainage, thus ensuring the smooth drainage of the drain hole 4.

[0168] Furthermore, such as Figure 5 As shown, the outer bottom wall 16 is flat at the radial sides of the groove 18. For example, the back of the water distribution tray 100 adopts a structure that is high in the middle and low on both sides, ensuring that both sides are a complete flat surface. This ensures perfect adhesion between the wet curtain 210 and the water distribution tray 100. The flat areas on both sides of the water distribution tray 100 are the glue application areas.

[0169] Furthermore, the outer bottom wall 16 corresponding to the drain channel 3 is at least 2 mm higher than the top of the wet curtain 210.

[0170] Furthermore, such as Figure 5 As shown, the disc body 1 includes an outer bottom wall 16. A drainage rib 124 is provided on the outer bottom wall 16 corresponding to the drain channel 3. The drainage rib 124 forms a drainage channel communicating with the drain hole 4. For example, a flange can be designed at the drain hole 4 to form the drainage rib 124. The drainage rib 124 can prevent water from spreading around the outer bottom wall 16 corresponding to the drain channel 3 due to the surface tension and viscosity of the water itself, thus affecting the drainage.

[0171] In any of the above embodiments, optionally, as Figure 2 As shown, the bottom wall of the diversion channel 5 is provided with a feature along the water flow direction (e.g., Figure 4 (The direction indicated by the arrow in the image) is a gradually rising slope 52.

[0172] In this embodiment, a slope is designed on the bottom wall of each diversion channel 5, such as at the tail end of the diversion channel 5, to raise the water flow. This slope forms a ramp surface 52. The ramp surface 52 can reduce the positive impact force of the water flow in the diversion channel 5 before diversion. After being buffered by the slope, the water flow can be diverted more evenly at the connecting port 30.

[0173] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the plate body 1 includes: a base 12; an upper cover 14, which is installed on the base 12 to cover the base 12; wherein, the water inlet 2 and the water outlet 4 are provided on the base 12, and the water outlet channel 3 and the diversion channel 5 are formed by the base 12 and the upper cover 14.

[0174] In this embodiment, the disc body 1 is enclosed by a base 12 and a top cover 14, thus forming a relatively enclosed water passage and preventing water from being exposed to the air. Specifically, to enclose the drainage channel 3 and the diversion channel 5, a groove can be provided on the inner side of the base 12 or the top cover 14, and then the drainage channel 3 and the diversion channel 5 are formed by the enclosure of the base 12 and the top cover 14. Alternatively, grooves can be provided on the inner sides of both the base 12 and the top cover 14 simultaneously to form the drainage channel 3 and the diversion channel 5.

[0175] In any of the above embodiments, optionally, as Figure 5 As shown, the chassis 12 is provided with one of a positioning post 142 and a positioning hole 122, and the upper cover 14 is provided with the other of a positioning post 142 and a positioning hole 122. The chassis 12 and the upper cover 14 are positioned and installed by the positioning post 142 and the positioning hole 122. The upper cover 14 is provided with a partition rib 144, and at least a portion of the partition rib 144 is inserted into the drain hole 4 to divide the drain hole 4 into multiple independently set water inlet channels.

[0176] In this embodiment, the positioning post 142 and the positioning hole 122 cooperate to achieve a limiting installation between the chassis 12 and the top cover 14, thereby making the relative position of the chassis 12 and the top cover 14 more accurate after installation. A dividing rib 144 is provided at the water inlet 2, so that the water in the water inlet 2 is initially divided into two branches, allowing for individual control of each branch. This arrangement, by dividing the water inlet 2 into multiple water channels, enables a more uniform water distribution in the water inlet 2, thus ensuring uniform water supply during the water supply process.

[0177] like Figure 5As shown, an embodiment of the second aspect of this application provides a wet curtain assembly 200, including: a wet curtain 210; and a water distribution tray 100 provided in any embodiment of the first aspect, the water distribution tray 100 being mounted on top of the wet curtain 210.

[0178] The wet curtain assembly 200 according to this application has all the beneficial effects of the water distribution tray 100 provided in any embodiment of the first aspect, since it includes the water distribution tray 100 provided in any embodiment of the first aspect, which will not be repeated here.

[0179] In any of the above embodiments, optionally, the middle part of the disk body 1 is provided with a portion along the thickness direction of the disk body 1 (i.e., Figure 5 The evaporative cooling pad 210 is arranged in a ring shape and forms an air passage 2102, with the air passage 10 connected to the air passage 2102. Multiple drain holes 4 are arranged at the radial center of the evaporative cooling pad 210.

[0180] In this embodiment, the center of the disc 1 is a hollow structure running vertically through it, forming an air passage 10. This air passage 10 corresponds to the air passage channel 2102 in the center of the evaporative cooling pad 210. Humidified air passing through the evaporative cooling pad 210 enters the air passage 10 through the air passage 2102 and then exits from the air passage 10. Multiple drain holes 4 are positioned radially at the center of the evaporative cooling pad 210, ensuring the drain holes 4 are relatively centered. This allows water in the drain holes 4 to fall to the central area at the top of the evaporative cooling pad 210 and then flow to both sides, making it easier to evenly wet the evaporative cooling pad 210. Of course, in other embodiments, the drain holes 4 can also be positioned at the edges of the evaporative cooling pad 210.

[0181] like Figure 5 and Figure 6 As shown, an embodiment of the third aspect of this application provides an air conditioning device 300, including the wet curtain assembly 200 provided in any embodiment of the second aspect.

[0182] The air conditioning device 300 proposed according to the embodiments of this application has all the beneficial effects of the evaporative cooling pad assembly 200 provided in any embodiment of the second aspect, since it includes the evaporative cooling pad assembly 200 provided in any embodiment of the second aspect, which will not be repeated here.

[0183] The air conditioning device 300 can specifically be a humidifier, an air purifier with humidification function, or a water-cooled fan.

[0184] In any of the above embodiments, optionally, the air conditioning device 300 is a humidifier, which further includes: a water tank 310; a wet curtain bracket 320 installed on the water tank 310, and a wet curtain assembly 200 installed on the wet curtain bracket 320; a water inlet pipe 330 installed on the wet curtain bracket 320 and extending to the water distribution plate 100, communicating with the water inlet hole 2; and a water pump 340 disposed in the water tank 310 and communicating with the inlet of the water inlet pipe 330.

[0185] In this embodiment, the air conditioning device 300 can specifically be a humidifier. This humidifier includes the aforementioned evaporative cooling pad assembly 200, which enables the water on the evaporative cooling pad 210 to be evenly distributed, thereby ensuring that the evaporative cooling pad 210 is uniformly wetted. Furthermore, the humidifier also includes a water tank 310, a water inlet pipe 330, and a water pump 340. Water in the water tank 310 can be pumped through the water pump 340 and the water inlet pipe 330 to the water inlet hole 2 of the water distribution plate 100, and the water in the water inlet hole 2 can flow through the drain hole 4 onto the evaporative cooling pad 210, thus achieving water supply to the evaporative cooling pad 210.

[0186] Furthermore, such as Figure 5 As shown, the wet curtain support 320 also includes a lower cover 230, which is installed at the bottom of the wet curtain 210. The lower cover 230 is provided with a water inlet channel 231, which is connected to the water supply pipe 330. A sealing element 240 is provided in the water inlet channel 231 to seal the gap between the water inlet channel 231 and the water supply pipe of the air conditioning device 300.

[0187] In this embodiment, the lower cover 230 is used to support the installation of the wet curtain 210 and connects the water inlet pipe 330 and the water tank 310 through the water inlet channel 231. The seal 240 is used to seal the gap between the water inlet channel 231 and the water supply pipe of the air conditioning device 300 to prevent the wet curtain 210 from leaking water.

[0188] Among them, the sealing element 240 is a silicone part.

[0189] The air conditioning unit 300 may specifically be a humidifier, an air purifier with humidification function, or a water-cooled fan.

[0190] In this embodiment, the humidifier is designed in the following way to ensure that the wet curtain 210 is fully wetted:

[0191] 1. A dividing rib 144 is provided at the water inlet 2. This design allows the water in the water inlet 2 to be pre-divided into multiple parts, so that the water distribution plate 100 can ensure that the water in the water inlet 2 can be evenly distributed to each distribution channel 5, whether it is placed horizontally or at an angle.

[0192] 2. At least two diversion channels 5 and at least two drainage channels 3 are provided on the disc body 1. In this structure, the water from the water inlet 2 is directly distributed to different areas of the disc body 1 by at least two diversion channels 5, and then drained from the drainage channels 3 of different areas. This arrangement, by first diverting the water to each area and then draining it from each area separately, makes the water distribution to different areas of the disc body 1 more uniform, thus making the drainage to different areas of the disc body 1 more uniform, thereby improving the water distribution uniformity of the water distribution disc 100.

[0193] 3. Each drainage channel 3 is divided into two drainage sub-channels. Dividing each drainage channel 3 into two symmetrically arranged drainage sub-channels can shorten the path of water flow after diversion, thereby making the drainage uniformity of the entire drainage channel 3 better controlled, thus improving the drainage uniformity of the water distribution plate 100.

[0194] This humidifier features a carefully designed structure for each stage of the water supply, distribution, and drainage. The structural design at the water inlet 2 ensures uniform water supply. Multiple distribution channels 5 and drainage channels 3 distribute water to various areas, enabling zoned water control and ensuring even drainage across different areas of the tray 1. Dividing the drainage channel 3 into two sub-channels shortens the water flow path, further enhancing drainage uniformity. Through this triple structural design, the humidifier effectively ensures uniform water flow at each node of the evaporative cooling pad 200, ultimately resulting in a uniform water distribution on the evaporative cooling pad 210.

[0195] like Figure 1 , Figure 7 and Figure 8 As shown, an embodiment of the fourth aspect of this application proposes a water distribution plate 100, comprising: a plate body 1; an inlet water hole 2 disposed on the plate body 1; a diversion channel 5 disposed on the plate body 1 and communicating with the inlet water hole 2; a drain channel 3 disposed on the plate body 1; and a plurality of drain holes 4 disposed within the drain channel 3; wherein the drain channel 3 includes a connecting port 30, a first drain sub-channel 32, and a second drain sub-channel 34, the first drain sub-channel 32 extending from the connecting port 30 along the circumference of the plate body 1 in a first direction, and the second drain sub-channel 34 extending from the connecting port 30 along the circumference of the plate body 1 in a second direction, and the first drain sub-channel 32 and the second drain sub-channel 34 are connected about a connecting line passing through the connecting port 30 and the center of the plate body 1 (e.g., ...). Figure 4 The straight line L2 in the middle or such Figure 7 , Figure 8 The straight line L3 in the middle or such Figure 8The straight lines (L4) are symmetrically distributed, or the paths of water flow from the connecting port 30 to the endpoints of the first drain sub-channel 32 and the second drain sub-channel 34 are equal. This includes the wet curtain assembly 200 provided in any embodiment of the second aspect.

[0196] The water distribution tray 100 proposed according to the embodiments of this application can be specifically used in an air conditioning device 300. Specifically, the water distribution tray 100 can be placed above the evaporative cooling pad 210 of the air conditioning device 300 to evenly distribute the water delivered to the evaporative cooling pad 210. Of course, the water distribution tray 100 can also be used in other products that require even water distribution, such as water-cooled fans. The water distribution tray 100 provided in this application includes a tray body 1, an inlet water hole 2, a diversion channel 5, a outlet water channel 3, and multiple outlet water holes 4. The inlet water hole 2 is the water inlet structure of the entire tray body 1, and the water that needs to be distributed by the water distribution tray 100 comes from the inlet water hole 2. The diversion channel 5 is connected to the inlet water hole 2 and is used to transport the water from the inlet water hole 2 to the outlet water channel 3. Simultaneously, the drainage channel 3 is divided into a first drainage sub-channel 32 and a second drainage sub-channel 34 from the connecting port 30. Both the first drainage sub-channel 32 and the second drainage sub-channel 34 extend circumferentially from the connecting port 30, but in opposite directions, for example, one extends clockwise and the other counterclockwise. The center of the disc body 1 is its center point. The connecting port 30 is symmetrically arranged about the first connecting line passing through the center point, and the first drainage sub-channels 32 and 34 are symmetrically distributed about the first connecting line. This ensures that the structures of the multiple drainage sub-channels are consistent, resulting in more uniform drainage. Alternatively, the paths from the connecting port 30 to the endpoint of the first drainage sub-channel 32 and the second drainage sub-channel 34 are equal, meaning the distance traveled by the water flowing from the connecting port 30 to the endpoint of each drainage sub-channel is the same. This ensures that the multiple drainage sub-channels are basically symmetrically arranged, further enhancing the uniformity of drainage. This scheme, by dividing each drainage channel 3 into two symmetrically arranged drainage sub-channels, can shorten the path of water flow after diversion, thereby making it easier to control the uniformity of drainage in the entire drainage channel 3, and thus improving the uniformity of drainage in the water distribution plate 100.

[0197] In any of the above embodiments, optionally, as Figure 1 , Figure 7 and Figure 8 As shown, there are at least two drainage channels 3, which are symmetrically distributed on the same circumferential direction of the disc body 1; there are at least two diversion channels 5, which are connected one-to-one with the connection ports 30 of the at least two drainage channels 3.

[0198] In this embodiment, at least two drainage channels 3 are independently configured, meaning they are not interconnected and are located in different areas of the basin 1. Water from the inlet holes 2 can be directly transported to the corresponding drainage channels 3 by at least two diversion channels 5. In other words, water from the inlet holes 2 is directly distributed to different areas of the basin 1 by the at least two diversion channels 5, and then drains from the drainage channels 3 of each area. This configuration, by first diverting water to each area and then draining it from each area separately, ensures that the water distribution in different areas of the basin 1 is relatively uniform, thus improving the water distribution uniformity of the water distribution basin 100.

[0199] Simultaneously, at least two drainage channels 3 are symmetrically arranged about the same axis of symmetry. This allows the drainage channels 3 on the tray 1 to be configured as two symmetrical halves. This enables the water entering the tray 1 to be initially divided into two independent portions, and then it is only necessary to ensure that each portion of water is subsequently distributed evenly. This scheme, by dividing the drainage channels 3 and the diversion channels 5 on the tray 1 into two parts, reduces the length of each drainage channel 3 compared to treating the channels on the tray 1 as a whole, thus facilitating the uniformity control of subsequent water drainage.

[0200] In any of the above embodiments, optionally, as Figure 1 and Figure 8 As shown, the diversion channel 5 includes a first diversion channel 5a and a second diversion channel 5b. The first diversion channel 5a and the second diversion channel 5b are equidistant from the water inlet 2 to their corresponding connecting port 30 (i.e., the water flows the same distance), or the first diversion channel 5a and the second diversion channel 5b are symmetrically arranged on both sides of the water inlet 2.

[0201] In this embodiment, the first diversion channel 5a and the second diversion channel 5b are symmetrically arranged about the water inlet 2. This allows some or all of the water in the water inlet 2 to be divided into two equal parts and sent to different drainage channels 3. For example, there can be only two diversion channels 5, which allows the water in the water inlet 2 to be divided into two parts for separate transportation, and then further divided into two branches in the drainage channel 3, thus forming four water distribution branches on the plate body 1.

[0202] In any of the above embodiments, optionally, as Figure 1 and Figure 8As shown, the diversion channel 5 includes a third diversion channel 5c and a fourth diversion channel 5d. The second distance from the water inlet 2 to the corresponding connecting port 30 of the third diversion channel 5c and the fourth diversion channel 5d is equal, or the third diversion channel 5c and the fourth diversion channel 5d are symmetrically arranged on both sides of the water inlet 2. The first diversion channel 5a and the second diversion channel 5b are arranged on the radial side of the disc body 1, and the third diversion channel 5c and the fourth diversion channel 5d are arranged on the radial side of the disc body 1. The first distance is greater than or less than the second distance.

[0203] In this embodiment, the disc 1 is provided with four diversion channels 5, which are symmetrically arranged about the water inlet 2. This ensures that the diversion channels 5 on each half of the disc 1 are identical, thus dividing the water flow in half along the central axis of the disc 1. In this scheme, the water flow on the disc 1 is first divided into four branches, and then each branch is further divided into two branches at the drain channel 3, thus forming eight branches on the disc 1. This scheme divides the water flow of the water distribution disc 100 into eight equal parts, that is, the entire disc 1 is divided into eight areas for drainage. This makes the water flow path in each area relatively short, thereby making it easier to control the subsequent uniformity of each water flow and better ensuring the uniformity of drainage from the water distribution disc 100.

[0204] Since the water inlet 2 is fixed, and the connecting port 30 is set in different positions, the length of the diversion channel 5 on each half of the plate 1 is inconsistent.

[0205] In any of the above embodiments, optionally, as Figure 1 As shown, the first diversion channel 5a and the second diversion channel 5b are arranged close to the inner side of the disk body 1 along the radial direction, and the third diversion channel 5c and the fourth diversion channel 5d are arranged close to the outer side of the disk body 1 along the radial direction; the first distance is greater than the second distance.

[0206] In this embodiment, the four diversion channels 5 are arranged symmetrically in pairs. In order to facilitate the placement of the drain channels 3 at the radial center of the wet curtain 210, the first diversion channel 5a and the second diversion channel 5b can be placed near the inner edge of the disc body 1, while the third diversion channel 5c and the fourth diversion channel 5d can be placed near the outer edge of the disc body 1. This way, the central area of ​​the disc body 1 can be reserved for the placement of the drain channels 3.

[0207] Since the water distribution channels are evenly distributed on the plate 1, the positions of the different connecting ports 30 are different, resulting in varying lengths of the different distribution channels 5 (i.e., the distance the water travels from the upper water hole 2 to the corresponding connecting port 30). In this application, the length of the distribution channels 5 on the inner edge is set to be longer, while the length of the distribution channels 5 on the outer edge is set to be shorter. That is, the distribution channels 5 on the inner edge correspond to connecting ports 30 at more distant positions, while the distribution channels 5 on the outer edge correspond to connecting ports 30 at closer positions. This arrangement can reduce the difference between the first distance and the second distance because, for the plate 1, the perimeter of the outer edge is longer and the perimeter of the inner edge is shorter. Therefore, the distribution channels 5 on the inner edge correspond to connecting ports 30 at more distant positions, making their overall path shorter.

[0208] The number of diversion channels 5 can be set to 1 as needed (e.g., Figure 7 As shown), 2 (as shown) Figure 8 (as shown), or 4 (as shown) Figure 1 (As shown). The number of drainage channels 3 can be set to 1 as needed (e.g., Figure 7 As shown), 2 (as shown) Figure 8 (as shown), or 4 (as shown) Figure 1 (As shown).

[0209] The structure of the water distribution plate 100 proposed in the fourth aspect of this application, the specific structure of the diversion channel 5, the structure of the drainage channel 3, and the specific structure of the plate body 1 can be set with reference to the water distribution plate 100 proposed in the first aspect of this application, and will not be described again here.

[0210] The following section uses a humidifier as an example to further illustrate the water tray in this application.

[0211] In conventional evaporative humidifiers, the drainage structure of the evaporative humidifier's cooling pad is achieved by simply opening a ring of holes and adjusting the number and diameter of the holes. This often results in faster drainage near the water inlet holes and slower drainage further away. Furthermore, for cooling pads with high humidification capacity and large diameters, more drainage holes are needed to ensure even drainage throughout the entire ring. To avoid this imbalance, the diameter of the drainage holes needs to be adjusted, with smaller diameters near the water inlet holes and larger diameters further away. With an increased number of drainage holes, it becomes difficult to properly adjust the gradual change in hole diameter to ensure uniform drainage.

[0212] This embodiment fundamentally solves the problem of water uniformity in the evaporative cooling pad 210. The water flow is evenly divided into four parts from the water inlet 2 on the top cover of the evaporative cooling pad, evenly distributed around the circular evaporative cooling pad 210. Simultaneously, the four water flow channels branching off from the water inlet 2 are each further divided into two segments, effectively dividing the entire circular evaporative cooling pad 210 from the conventional left-right symmetrical distribution into eight equal parts. Furthermore, depending on the specific situation of the evaporative cooling pad 210, it can be further divided into 16 or more parts to ensure uniform water flow. This configuration guarantees the uniformity of water flow from the evaporative cooling pad 210, ensuring sufficient wetting of the evaporative cooling pad 210 and maximizing humidification performance under the same airflow. Moreover, this solution is independent of the diameter of the evaporative cooling pad 210; the diameter of the evaporative cooling pad 210 can be arbitrarily changed, and this distribution structure can be directly utilized.

[0213] Specifically, the present invention relates to a humidifier and a evaporative cooling pad 210 for the humidifier, wherein the evaporative cooling pad drainage structure includes:

[0214] The top cover of the wet curtain (i.e., the top cover 14): together with the wet curtain fixing cover, it forms a closed and sealed structure, and the top surface is the top appearance surface of the entire wet curtain 210; at the same time, through a special structure, the water coming from the inlet pipe is initially divided into 4 equal parts;

[0215] The wet curtain fixing cover (i.e., chassis 12) is the main component for water circulation and diversion. Together with the wet curtain top cover, it forms a circulation sealing structure, which allows water to flow only through specific routes and specific drain holes 4 to the wet curtain 210 to complete the humidification of the wet curtain 210; it mainly forms four basically identical diversion and drainage areas.

[0216] The wet curtain 210 is fixed to the wet curtain fixing cover and the wet curtain bottom cover with glue at the top and bottom respectively. At the same time, water flowing out from the specific water outlet of the wet curtain fixing cover wets the wet curtain 210, and through the air flow, it completes the humidification of the surrounding environment.

[0217] Water inlet pipe 330: It is installed between the wet curtain fixing cover and the wet curtain bottom cover by cooperating with the bottom silicone part. It passes through the area of ​​wet curtain 210, and wet curtain 210 needs to make a special gap to avoid it; its main function is to transport the water from the bottom of the machine to the top of wet curtain 210 by the water pump.

[0218] The bottom cover of the wet curtain (i.e., the bottom cover 230) mainly supports the bottom of the wet curtain 210. The bottom of the wet curtain 210 is fixed by adhesive that contacts the bottom of the wet curtain 210. At the same time, the bottom cover of the wet curtain has a drainage hole. Excess water flowing from the wet curtain 210 flows through the drainage pipe of the bottom cover of the wet curtain and flows back to the water tank 310 of the machine.

[0219] Silicone component (i.e., sealing component 240): mainly through the deformable and compressible characteristics of silicone component, the entire wet curtain assembly 200 is connected to the water inlet hole 2 of the machine body through silicone component, and water is ensured to flow upward through water inlet pipe 330;

[0220] In common evaporative humidifiers, the rotation of a centrifugal fan at the top of the unit creates a negative pressure around the fan, drawing air from the bottom of the unit inwards. This air then passes through the evaporative cooling pad assembly 200 and exits through the top air outlet. The evaporative cooling pad 210 material around the evaporative cooling pad assembly 200 is highly absorbent. Water flowing from the drain holes at the top of the evaporative cooling pad 210 spreads evenly around the assembly due to gravity and the material's absorbency, continuously wetting the pad. The area around the evaporative cooling pad assembly 200 is covered with moist water molecules. When dry air flows past the assembly, it carries away these water molecules, thus humidifying the air. As the air circulates and water flows down from the drain holes at the top of the evaporative cooling pad 210, the pad itself is continuously wetted, achieving the goal of continuously humidifying the air.

[0221] Disadvantages during the process: Ideally, the evaporative cooling pad assembly 200 should ensure that the water transported by the pump from the water inlet pipe 330 is evenly distributed to all parts of the evaporative cooling pad 210. There is only one water inlet hole 2, which is generally a round hole with a diameter of 6mm-12mm. The evaporative cooling pad 210 is a circle. How to ensure that the water transported from a small hole is evenly distributed to the entire circle of the evaporative cooling pad 210 is a challenge. If the water flow cannot be evenly distributed, some areas of the evaporative cooling pad 210 will be very wet, while some areas will be dry, or some areas will not be thoroughly wetted. This will greatly affect the humidification performance.

[0222] This embodiment introduces a method that can effectively solve the problem of uneven water distribution in this type of evaporative humidifier:

[0223] Firstly, the water coming up through the water inlet 2 is divided into four equal parts by the special circular cross-rib structure on the upper cover 14 before entering the wet curtain fixing cover for diversion. The inner diameter of the water inlet 2 is generally around 6mm-12mm. The water inlet pipe 330 is vertical relative to the wet curtain assembly 200. The water flow inside the water inlet pipe 330 is fast and full. Due to the small diameter, there is no uneven water flow inside the water inlet pipe 330. The water flow in each cross section completely fills the entire inner hole. During the upward process, it is divided by the cross-rib structure of the water inlet pipe 330. The water flow is evenly divided into four parts, ensuring that the water flow to the four main flow paths on the wet curtain fixing cover is the same. The advantage of this design is that it can ensure the even distribution of water flow regardless of whether the machine is placed on a flat or inclined surface. When placed on an inclined surface, although the wet curtain assembly 200 is also inclined, the water inlet pipe 330 is vertical relative to the wet curtain assembly 200. The water flow inside the water inlet pipe 330 is always full. The cross rib on the top cover 14 is perpendicular to the inner hole of the water inlet pipe 330. The two are always in a perpendicular state, so the water flow can always be evenly divided into four parts.

[0224] Water flows through the top cover, which divides the water into four equal parts, and then flows to the wet curtain fixing cover. With the wet curtain fixing cover and the wet curtain top cover sealing each other, four water flow channels are also formed inside the wet curtain fixing cover, starting from the water inlet 2 position and matching the cross rib position of the wet curtain top cover. The water volume of the four water flow channels is equal. Since the wet curtain 210 is a standard circle, all the flow channels that come from the water inlet pipe 330 can be regarded as a whole as the first flow path and the second flow path as one group, and the third flow path and the fourth flow path as another group. Each group has a 180° area of ​​water discharge, and the structure and flow path between the two groups are the same.

[0225] The flow path of a separate group will be described in detail below.

[0226] The first and second flow paths are responsible for the uniform distribution of water flow in the 0° to 180° region on the left. The two flow paths can be further subdivided into the first flow path being responsible for the uniform distribution of water flow from 0° to 90°, and the second flow path being responsible for the uniform distribution of water flow from 90° to 180°.

[0227] To ensure optimal humidification of the evaporative cooling pad 210, the drain holes 4 of the cylindrical evaporative cooling pad 210 are preferably distributed around the very center of the circular ring. This ensures that the water flowing from the drain holes 4 evenly humidifies both the inner and outer sides of the evaporative cooling pad 210. With the drain holes 4 in the center, the flow distribution area can only be designed around the drain holes 4 on both the inner and outer sides. The first flow path is on the outer side of the drain holes 4. After a short transport distance, the water flows through a near 90° bend, changing its position and guiding the outer water flow towards the center. After the bend, it travels a short straight distance to ensure that the water flow direction is uniform and vertical. At this point, the water flow is further divided into two branches, forming the first and second branch water distribution paths. The first branch water distribution path is responsible for the uniform distribution of water flow in the 45°-90° area, and the second branch water distribution path is responsible for the uniform distribution of water flow in the 0°-45° area.

[0228] At this point, a small branch only needs to ensure uniform water flow in the two drain holes 4. The two holes of the first branch are opened by small gates in the water flow channel to allow the water flow of the first branch to enter the first hole. The end point of the first flow path of the second hole does not need to be designed with a gate; it is directly at the center of the flow path. At this point, the first branch only needs to adjust the size of the gate and the size of the two drain holes 4 to control the uniformity of water flow in the two small holes. Since the water volume of the first branch is now only 1 / 8 of the total water volume after the first four divisions and the second two divisions of the total inlet pipe, the water volume has obviously decreased. By adjusting the size of the gate and the diameter of the hole, the uniformity of water flow can be well guaranteed. After confirming and adjusting the structure of the first branch, the specific gate size and diameter can be applied to the remaining 7 / 8 area because the water flow and water path are basically the same.

[0229] The structure of the second flow path is the same as that of the first flow path.

[0230] The second flow path needs to ensure drainage in the 90°-180° area. By grooving the inside of the drainage hole 4 and transporting the water to the 135° area, it makes the same near 90° turn and a short straight section to ensure that the direction of water flow is consistent. At this point, it continues to split into two to form the third and fourth water branch paths. The third water branch path is responsible for drainage in the 90°-135° area, and the fourth water branch path is responsible for drainage in the 135°-180° area. Each branch path is responsible for drainage from two holes. The local design is the same as the first and second water branch paths mentioned above.

[0231] In addition, besides the first water branch, each other branch is designed with a drain hole at the end. When there is too much water and it cannot flow out completely through the drain hole 4, it will enter the drain area on both the inner and outer sides of the wet curtain fixing cover through the small gate at the end of the branch. The excess water flows to the wet curtain 210 through the drain hole. The full utilization of the complete water flow also ensures that the internal water flow forms a circulation path, avoiding excessive sealing and the formation of internal air bubbles, which would prevent the water flow from circulating normally and ensure the overall internal air pressure balance.

[0232] Special Note:

[0233] 1. The first flow path and the second flow path of this scheme are interchangeable, that is, the first flow path is designed on the inside and the second flow path is designed on the outside.

[0234] 2. This scheme is based on dividing the entire circumference of the wet curtain fixing cover into 16 holes. Each large branch is responsible for 4 holes, and each small branch is responsible for 2 holes. The number of holes can be varied according to the diameter of the wet curtain 210, increasing or decreasing in multiples of 4 each time. It can be further divided into multiple sub-branches based on the first water distribution branch. The scheme is similar, the key is to ensure that the water is evenly distributed to each hole and to divide the entire circumference of the drainage into similar small blocks.

[0235] 3. The third and fourth flow paths are exactly the same as the first and second flow paths, and can be designed symmetrically.
