Description

Technical Field

[0001] The present application relates to the technical field of household electrical appliances, and in particular to a wet curtain assembly and an air conditioning device. Background Art

[0002] In the relevant solutions, for products such as humidifiers, purifiers, and water-cooled fans, the wet curtain assembly needs to be equipped with a water distribution tray to evenly distribute water to the wet curtain. However, in the relevant solutions, the water distribution tray is not designed properly, and the water distribution is uneven, which leads to uneven water distribution on the wet curtain.

[0003] Therefore, how to design a wet curtain assembly 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 technical problem of uneven distribution of water distribution plates of wet curtain assemblies in the prior art or related art.

[0005] Therefore, an object of the present invention is to provide a wet curtain assembly.

[0006] An embodiment of the second aspect of the present application provides an air conditioning device.

[0007] To achieve the above-mentioned purpose, the technical solution of the first aspect of the present invention provides a wet curtain assembly for an air conditioning device, the wet curtain assembly comprising: a wet curtain; a water diversion tray, the water diversion tray is installed on the top of the wet curtain, the water diversion tray comprises: a tray body; a first channel, arranged on the tray body; a second channel, arranged on the tray body and arranged along the circumference of the tray body; a plurality of first water discharge holes, arranged in the second channel at intervals along the circumference of the tray body; a connecting channel, arranged between the first channel and the second channel, for connecting the first channel and the second channel when the water level in the first channel reaches a first preset water level.

[0008] The wet curtain assembly provided according to the technical solution of the present invention includes a wet curtain and a water distribution plate, and the water distribution plate is installed on the top of the wet curtain. The water distribution plate includes a plate body, a first channel, a second channel, a plurality of first water discharge holes and a connecting channel. Among them, the first channel is arranged on the plate body, the second channel is arranged on the plate body, and is distributed along the circumference of the plate body, and the connecting channel is arranged between the first channel and the second channel, and can connect the first channel and the second channel when the water level in the first channel reaches the first preset water level. Among them, the water in the first channel enters the second channel through the connecting channel, and then is discharged from the first water discharge hole of the second channel. In this scheme, since the water flow in the second channel mainly comes from the first channel, the water flow direction of the water entering the second channel has been converted by a certain angle (approximately 90°) in the process of flowing into the second channel, thereby greatly eliminating the impact force of the water flow just flowing out of the upper water hole, thereby making the first water discharge hole rely solely on gravity, reducing the impact of the water flow impact force on the discharge of the first water discharge hole, thereby making the discharge of multiple first water discharge holes more uniform.

[0009] There is a height difference between the connection point between the connecting channel and the first channel and the inner bottom wall of the first channel, and the height difference makes it possible for the water in the first channel to enter the second channel from the connecting channel only when it reaches a certain water level (i.e., the first preset water level). The first preset water level is a design water level, and the design water level mainly depends on the height position of the connecting channel. With this arrangement, water will enter the second channel only after the first channel is filled with a certain amount of water along the entire circumferential direction, and then flow from the first water discharge hole of the second channel to the wet curtain. In this way, the water in the first channel can basically flow into the second channel synchronously, and then flow to the wet curtain synchronously, so that the uniformity of the water discharge can be ensured, so that each position of the wet curtain is basically in contact with water at the same time, so that the wet curtain can be ensured to be evenly wetted, and avoid the situation where some positions of the wet curtain are first in contact with water to be fully wetted, while some positions are still dry.

[0010] On the contrary, if the connecting channel is set relatively low or even flush with the inner bottom wall of the first channel, the connecting channel closer to the water supply position will contact the water first, while the connecting channel farther from the water supply position will contact the water later, which will cause the wet curtain to contact the water at different times at different positions, which will easily lead to uneven wetting of the wet curtain. Based on the improvement of the present application, the problem of uneven water discharge caused by the difference in distance between different connecting channels and the water supply position is solved, thereby effectively ensuring the uniformity of water discharge.

[0011] In some possible technical solutions, optionally, a connection position between the communicating channel and the first channel is higher than an inner bottom wall surface of the first channel.

[0012] In these technical solutions, the entrance of the connecting channel is set at the upper end of the first channel, and there is a certain height difference between it and the inner bottom wall of the first channel, so that the water needs to fill the first channel for a whole circle before overflowing from the connecting channel and entering the second channel. In this way, the height difference between the entrance of the connecting channel and the inner bottom wall of the first channel can ensure that the water in the first channel can enter the second channel only after reaching a certain water level. In this way, there is no need to set up an additional switch structure, making the structure of the water distribution plate relatively simple. Among them, in this setting, the size of the first preset water level depends on the height difference between the entrance of the connecting channel and the inner bottom wall of the first channel.

[0013] Of course, in order to ensure that the water in the first channel can enter the second channel only after reaching a certain water level, a switch structure can also be set at the entrance of the connecting channel, and it is required that the switch structure can only be opened after the water in the first channel reaches a first preset water level.

[0014] In any of the above technical solutions, optionally, the surface of the first channel and the second channel close to one end of the wet curtain is the first inner bottom wall surface, and along the height direction of the wet curtain, the first inner bottom wall surface of the second channel is higher than the first inner bottom wall surface of the first channel.

[0015] In these technical solutions, the inner bottom wall of the second channel is the highest, so that it is convenient to set a corresponding annular groove on the outer bottom of the second channel to facilitate the discharge of water from the first drain hole. At the same time, this arrangement can also make the inner bottom wall of the first channel lower, so as to ensure that there is a certain height difference between the connecting channel and the inner bottom wall of the first channel, thereby ensuring that the water in the first channel can enter the second channel only after reaching a certain water level.

[0016] In some possible technical solutions, optionally, the wet curtain assembly further includes: an upper water hole, arranged in the first channel to supply water to the first channel; or a water supply channel, connected to the first channel to supply water to the first channel.

[0017] In these technical solutions, the wet curtain assembly further includes an upper water hole, which is arranged in the first channel, and the water to be distributed is transported into the first channel through the upper water hole. Alternatively, the wet curtain assembly further includes a water supply channel, which is connected to the first channel, and the water to be distributed is transported into the first channel through the water supply channel.

[0018] In some possible technical solutions, optionally, the surface of the disk body close to the wet curtain is the first bottom surface, the portion of the first bottom surface corresponding to the first channel abuts against the top of the wet curtain, and a water gap is provided between the portion of the first bottom surface corresponding to the second channel and the top of the wet curtain.

[0019] In these technical solutions, the portion of the first bottom surface corresponding to the first channel abuts against the top of the wet curtain, so that the water diversion tray can be supported by the wet curtain. A water gap is provided between the portion of the first bottom surface corresponding to the second channel and the top of the wet curtain. The provision of the water gap can ensure the smoothness of the first water discharge hole and prevent the first water discharge hole from being blocked by the wet curtain, thereby ensuring the water discharge efficiency.

[0020] In some possible technical solutions, optionally, the water gap is formed by the second channel being recessed from the first bottom surface toward a direction away from the wet curtain. Or the water gap is formed by the top of the wet curtain being recessed toward a direction away from the water distribution plate. Or the portion of the first bottom surface corresponding to the first channel is convexly arranged in a direction close to the wet curtain relative to the portion of the first bottom surface corresponding to the second channel, so as to form the water gap.

[0021] In some possible technical solutions, optionally, the wet curtain assembly also includes: a third channel, which is arranged on the disk body and is located on one side of the second channel along the radial direction of the disk body. The third channel has an overflow channel arranged along the circumference of the disk body, which is used to connect the second channel and the third channel when the water level in the second channel reaches a second preset water level.

[0022] In these technical solutions, the wet curtain assembly also includes a third channel and an overflow channel. The third channel is arranged on the disc body, and is located on one side of the second channel along the radial direction of the disc body, and the third channel is arranged along the circumference of the disc body. The overflow channel can connect the second channel and the third channel when the water level in the second channel reaches the second preset water level, so that when the water is not discharged in time from the first drain hole, the water can enter the third channel from the overflow channel at the top of the second channel, and then flow out from the third channel, thereby playing a role of drainage through the third channel. At the same time, the overflow channel can also ensure that the water flow inside the water distribution tray forms a circulation passage, avoiding the water distribution tray from being too closed inside, forming internal bubbles, and causing the water flow to be unable to circulate normally, thereby ensuring the air pressure balance inside the water distribution tray and avoiding the backflow of water in the second channel.

[0023] By setting the second preset water level, it can be ensured that the upper water hole and the first channel can normally transport water to the second channel for drainage. In the present application, water will overflow from the second channel to the third channel only after the first drainage hole is blocked and the water level in the second channel rises to a certain height (i.e., the second preset water level).

[0024] There is a height difference between the overflow channel and the inner bottom wall of the second channel, so that water can be ensured to overflow from the overflow channel only when a certain water level is reached in the third channel.

[0025] In some possible technical solutions, optionally, the wet curtain assembly further includes: a second water drop hole, which is arranged in the third channel, and the water in the third channel can flow to the wet curtain or the water tank through the second water drop hole.

[0026] In these technical solutions, a second drain hole can be arranged in the third channel, so that when the first drain hole fails to drain water in time, water can enter the third channel from the overflow channel at the top of the second channel, and then flow from the second drain hole to the wet curtain or water tank, thereby playing a role of drainage through the second drain hole. At the same time, this arrangement can also recycle the water in the third channel, thereby improving the utilization rate of water.

[0027] In some possible technical solutions, optionally, the surface of the disk body on one side close to the wet curtain is a first bottom surface, and a portion of the first bottom surface corresponding to the third channel abuts against the top of the wet curtain.

[0028] In these technical solutions, the water diversion tray can be supported by the wet curtain because the portion of the first bottom surface corresponding to the third channel abuts against the wet curtain.

[0029] In some possible technical solutions, optionally, a water supply hole is provided in the first channel, the first channel is provided along the circumference of the disk body, and along the radial direction of the disk body, the second channel is located between the first channel and the third channel.

[0030] In these technical solutions, the upper water hole can be connected to the water tank so that the water in the water tank can be directly transported to the first channel. The first channel is arranged in a ring shape along the circumference of the disc body, so that the first channel can be evenly distributed along the circumference of the wet curtain, thus ensuring the uniformity of water discharge. By arranging the second channel between the first channel and the third channel, it can be ensured that the water in the first channel can flow smoothly into the second channel, and it can also be ensured that when the water in the second channel overflows, it can be discharged through the third channel.

[0031] In some possible technical solutions, optionally, a recessed portion recessed toward the wet curtain is provided in the first channel, and the upper water hole is provided in the recessed portion.

[0032] In these technical solutions, the water in the upper water hole needs to fill the recessed portion before it will flow from both circumferential sides of the upper water hole along the circumference of the first channel. In this way, the speed of the water flow entering the first channel can be slowed down by the recessed portion, so that the water can enter the second channel at a natural flow speed, thereby making the water more evenly distributed on the water distribution plate.

[0033] In some possible technical solutions, optionally, the wet curtain assembly further includes: a partition rib, which is arranged at the upper water hole and is used to divide the first channel into two parts along the circumference of the disc body.

[0034] In this technical solution, a dividing rib is provided at the upper water hole, which can divide the first channel into two parts along the circumferential direction, that is, the water of the upper water hole is divided into two branches at the beginning, so that each branch can be controlled separately. This setting directly reduces the control variables by half by dividing the first channel into two water flow channels, so that it is easier to adjust and meet the uniformity of water discharge of multiple first water discharge holes.

[0035] At the same time, this scheme can ensure the uniformity of water supply through the structural design of the upper water hole, can ensure the uniformity of water distribution time through the position design of the connecting channel, and can ensure the uniformity of water distribution through the design of multiple first lower water holes. The uniformity of water discharge can be ensured. In this way, through this triple structural design, the uniformity of water flow at each node of the wet curtain assembly is fully ensured, so that the water on the wet curtain can be evenly distributed.

[0036] In some possible technical solutions, optionally, along the height direction of the wet curtain, the inner bottom wall of the second channel has a height difference with the inner bottom wall of the first channel, and the height difference is greater than 0 mm and less than or equal to 7 mm. This height difference can effectively prevent the first drain hole from being blocked and prevent noise caused by excessive water drop.

[0037] In some possible technical solutions, optionally, the diameter of the first water discharge hole is greater than or equal to 1.5 mm and less than or equal to 5 mm, so as to ensure smooth water discharge and avoid discontinuous water discharge due to excessive water flow.

[0038] In some possible technical solutions, optionally, the opening width of the communication channel along the circumference of the disk body is greater than or equal to 1 mm and less than or equal to 5 mm, so as to ensure smooth water discharge and avoid discontinuous water discharge caused by excessive water flow.

[0039] In some possible technical solutions, optionally, there are multiple communicating channels, and the opening areas of the multiple communicating channels increase from the upstream side to the downstream side of the first channel.

[0040] In these technical solutions, for the first channel, the position of the connecting channel is different, and the water flow passing through it is different. For example, the connecting channel on the upstream side contacts the water flow first, and the connecting channel on the downstream side contacts the water flow later. Therefore, in order to ensure the uniformity of water discharge in the upstream and downstream connecting channels, the opening size of the connecting channel can be set according to the actual position of the connecting channel to adjust the flow rate of the connecting channel to ensure the uniformity of water discharge in the connecting channels at different positions. Specifically, the connecting channel on the upstream side can be set smaller, and the connecting channel on the downstream side can be set larger to ensure the uniformity of water flow entering the second channel through multiple connecting channels.

[0041] In some possible technical solutions, optionally, a connecting channel is provided at the midpoint between any two adjacent first water discharge holes.

[0042] In this technical solution, the connecting channel and the first drain hole are staggered, that is, the connecting channel is arranged between two adjacent first drain holes. The staggered connecting channel and the first drain hole make the water flowing out of the connecting channel not flow directly into the first drain hole, and the water flowing out of the connecting channel will flow directly to the side wall of the second channel, so that the water flow is turned, and then the water flow can be diverted, and the water flow in the second channel is more moderate. Secondly, this arrangement makes one connecting channel correspond to the arrangement of two first drain holes, so that the number of connecting channels is relatively moderate, avoiding too few connecting channels, which leads to a slow water inlet speed of the second channel, and at the same time, it can also avoid too many connecting channels, which leads to too fast water flow, and the first channel loses the effect of buffering impact force.

[0043] In some possible technical solutions, optionally, the surface of the disk body close to the wet curtain is a first bottom surface, and one end of the plurality of first drain holes close to the wet curtain is lower than a portion of the first bottom surface corresponding to the second channel.

[0044] In this technical solution, the surface of the pan body close to the wet curtain is the first bottom surface, and the first bottom surface is the lower surface of the pan body. The end of the plurality of first drain holes close to the wet curtain is lower than the portion of the first bottom surface corresponding to the second channel. That is, the first drain holes extend toward the wet curtain and protrude from the bottom of the second channel. This arrangement allows the water discharged from the first drain holes to fall directly and is not easy to flow along the lower surface of the pan body.

[0045] In some possible technical solutions, optionally, the tray body includes: a chassis; an upper cover installed on the chassis to seal the chassis; wherein the first drain hole is arranged on the chassis, and the first channel, the second channel and the connecting channel are surrounded by the chassis and the upper cover.

[0046] In this technical solution, the dish body is surrounded by a bottom plate and an upper cover, so that a relatively closed water passage can be formed to prevent water from being exposed to the air. In order to enclose the first passage, the second passage and the connecting passage, a groove can be provided on the inner side of the bottom plate or the upper cover, and then the first passage, the second passage and the connecting passage are formed by the enclosure of the bottom plate and the upper cover. Of course, grooves can also be provided on the inner sides of the bottom plate and the upper cover at the same time to form the first passage, the second passage and the connecting passage.

[0047] In some possible technical solutions, optionally, the wet curtain assembly also includes: a first barrier rib, which is arranged on the chassis and is arranged in a ring shape along the circumference of the chassis; a second barrier rib, which is arranged on the chassis and is arranged in a ring shape along the circumference of the chassis, and the second barrier rib is arranged on the outside of the first barrier rib along the radial direction of the chassis; a third barrier rib, which is arranged on the chassis and is arranged in a ring shape along the circumference of the chassis, and the third barrier rib is arranged on the outside of the second barrier rib along the radial direction of the chassis; a fourth barrier rib, which is arranged on the chassis and is arranged in a ring shape along the circumference of the chassis, and the fourth barrier rib is located on the outside of the third barrier rib along the radial direction of the chassis; wherein the first channel is surrounded by the chassis, the upper cover, the first barrier rib and the second barrier rib, the second channel is surrounded by the chassis, the upper cover, the second barrier rib and the third barrier rib, the chassis, the upper cover, the fourth barrier rib and the third barrier rib form the third channel, and the connecting channel is a gap arranged in the second barrier rib.

[0048] In this technical solution, the wet curtain assembly also includes: a first baffle, a second baffle, a third baffle and a fourth baffle, wherein the first baffle, the second baffle and the third baffle are arranged in a ring shape along the circumference of the disk body. And the second baffle is arranged on the outside of the first baffle along the radial direction of the disk body. The third baffle is arranged on the outside of the first baffle along the radial direction of the disk body. The fourth baffle is an annular baffle, which is arranged on the outermost side. In other words, the four baffles enclose three channels in sequence from the inside to the outside. With this arrangement, the required channels can be quickly and conveniently formed on the disk body through the four baffles, thereby facilitating the processing of the disk body and reducing the cost of the disk body. At the same time, a notch can be set on the second baffle to form a connecting channel to achieve the connection between the first channel and the second channel.

[0049] In any of the above technical solutions, optionally, a gap is provided between the third barrier rib and the upper cover along the height direction of the wet curtain.

[0050] In this technical solution, the gas and water in the second channel can flow into the third channel through the gap, that is, an overflow channel can be formed through the gap.

[0051] The technical solution of the second aspect of the present application proposes an air conditioning device, including a wet curtain assembly provided by any technical solution of the first aspect; the air conditioning device includes at least one of a humidifier, an air purifier and a water-cooled fan.

[0052] The air conditioning device proposed according to the technical solution of the present application includes the wet curtain assembly provided by any one of the technical solutions of the first aspect. Therefore, the air conditioning device has all the beneficial effects of the wet curtain assembly provided by any one of the technical solutions of the first aspect, which will not be repeated here.

[0053] In any of the above technical solutions, optionally, the humidifier further includes a water tank and a water pump, and the water pump is used to transport the water in the water tank to the water diversion plate. The water diversion plate is provided with an upper water hole, and a dividing rib is provided at the upper water hole. The dividing rib can divide the first channel into two parts along the circumferential direction, that is, the water in the upper water hole is divided into two branches at the beginning, so that each branch can be controlled separately. At the same time, a recessed portion recessed in the direction of the wet curtain is provided in the first channel of the water diversion plate, and the upper water hole is provided in the recessed portion. Further, the first channel and the second channel of the water diversion plate are connected through a connecting channel, and the connecting channel connects the first channel and the second channel only when the water level in the first channel reaches a first preset water level. Further, a height difference is provided between the connection between the connecting channel and the first channel and the inner bottom wall of the first channel, and the height difference enables the water in the first channel to enter the second channel from the connecting channel only when a certain water level (i.e., the first preset water level) is reached.

[0054] With this arrangement, water will enter the second channel only after the first channel is filled with a certain amount of water along the entire circumferential direction, and then flow from the first water outlet hole of the second channel to the wet curtain. Furthermore, evenly distributed first water outlet holes are provided in the second channel of the water distribution plate, so that the water in the second channel can flow evenly to the wet curtain. This humidifier directly reduces the control variable by half by dividing the first channel into two water flow channels, so that it is easier to adjust and meet the uniformity of water discharge of multiple first water outlet holes. The design of the recessed portion is that the water in the upper water hole needs to fill the recessed portion before it flows along the circumference of the first channel from both sides of the upper water hole. In this way, the speed of the water flow entering the first channel can be slowed down by the recessed portion, so that the water can enter the second channel at a natural flow speed, so that the water can be more evenly distributed on the water distribution plate. By designing the position of the connecting channel, a height difference can be set between the connection between the connecting channel and the first channel and the inner bottom wall of the first channel. In this way, water will enter the second channel only after the first channel is filled with a certain amount of water along the entire circumferential direction, and then flow to the wet curtain from the first water discharge hole of the second channel. In this way, the water in the first channel can basically flow into the second channel and then flow to the wet curtain simultaneously, thereby ensuring the uniformity of water discharge, so that each position of the wet curtain is basically in contact with water at the same time, thus ensuring that the wet curtain is evenly wetted, and avoiding the situation that some positions of the wet curtain are first in contact with water to be fully moistened, while some positions are still dry. This type of humidifier has been structurally designed in each link from water supply to water distribution to water discharge. The structural design at the water supply hole can ensure the uniformity of water supply. The position design of the connecting channel can form a height difference, so that only after the first channel is filled with a certain amount of water along the entire circumferential direction, the water will enter the second channel, and then flow from the first water discharge hole of the second channel to the wet curtain. In this way, the uniformity of water distribution time can be ensured to ensure the uniformity of water distribution. The design of multiple first water discharge holes can ensure the uniformity of water discharge. In this way, through this triple structural design, the uniformity of water flow at each node of the wet curtain assembly is fully ensured, so that the water on the wet curtain can be evenly distributed. Among them, the air conditioning device can be specifically a humidifier, an air purifier with a humidification function, or a water-cooled fan.

DETAILED DESCRIPTION

[0065] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0067] Refer to the following Figures 1 to 6 The wet curtain assembly 200 and the air conditioning device 300 provided in the embodiment of the present application are described.

[0068] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an embodiment of the first aspect of the present invention provides a wet curtain assembly 200 for an air conditioning device 300. The wet curtain assembly 200 includes a wet curtain 210 and a water separation plate 100. The water separation plate 100 is installed on the top of the wet curtain 210. The water separation plate 100 includes: a plate body 1; a first channel 3, which is arranged on the plate body 1; a second channel 4, which is arranged on the plate body 1 and is arranged along the circumference of the plate body 1; a plurality of first water discharge holes 42, which are arranged in the second channel 4 at intervals along the circumference of the plate body 1; a connecting channel 5, which is arranged between the first channel 3 and the second channel 4, and is used to connect the first channel 3 and the second channel 4 when the water level in the first channel 3 reaches a first preset water level.

[0069] The wet curtain assembly 200 provided according to an embodiment of the present invention includes a wet curtain 210 and a water separation tray 100, and the water separation tray 100 is installed on the top of the wet curtain 210. The water separation tray 100 includes a tray body 1, a first channel 3, a second channel 4, a plurality of first water discharge holes 42 and a connecting channel 5. The first channel 3 is arranged on the tray body 1, the second channel 4 is arranged on the tray body 1, and is distributed along the circumference of the tray body 1, and the connecting channel 5 is arranged between the first channel 3 and the second channel 4, and can connect the first channel 3 and the second channel 4 when the water level in the first channel 3 reaches the first preset water level. The water in the first channel 3 enters the second channel 4 through the connecting channel 5, and then is discharged from the first water discharge hole 42 of the second channel 4. In this solution, since the water flow in the second channel 4 mainly comes from the first channel 3, the direction of the water entering the second channel 4 has been converted by a certain angle (approximately 90°) during the process of flowing into the second channel 4, thereby greatly eliminating the impact force of the water just flowing out of the upper water hole 2, so that the first water discharge hole 42 relies solely on gravity to discharge water, reducing the influence of the impact force of the water flow on the discharge of the first water discharge hole 42, thereby making the discharge of multiple first water discharge holes 42 more uniform.

[0070] Among them, Figure 3 and Figure 4As shown, a height difference H1 is set between the connection point of the connecting channel 5 and the first channel 3 and the inner bottom wall of the first channel 3. The height difference H1 enables the water in the first channel 3 to enter the second channel 4 from the connecting channel 5 only when it reaches a certain water level (i.e., the first preset water level). Among them, the first preset water level is a design water level, and the design water level mainly depends on the height position of the connecting channel 5. In this arrangement, only when the first channel 3 is filled with a certain amount of water along the entire circumferential direction, the water will enter the second channel 4, and then flow from the first water discharge hole 42 of the second channel 4 to the wet curtain 210. In this way, the water in the first channel 3 can basically flow into the second channel 4 synchronously, and then flow to the wet curtain 210 synchronously, so that the uniformity of the water discharge can be ensured, so that each position of the wet curtain 210 is basically in contact with water at the same time, so that the wet curtain 210 can be ensured to be evenly wetted, and avoid the situation that some positions of the wet curtain 210 are first in contact with water to be fully wetted, while some positions are still dry.

[0071] On the contrary, if the connecting channel 5 is set relatively low or even flush with the inner bottom wall of the first channel 3, the connecting channel 5 closer to the water supply position will contact the water first, while the connecting channel 5 farther from the water supply position will contact the water later, which will cause the time when different positions of the wet curtain 210 contact the water to be different, which will easily cause uneven wetting of the wet curtain 210. Based on the improvement of the present application, the problem of uneven water discharge caused by the difference in distance between different connecting channels 5 and the water supply position is solved, thereby effectively ensuring the uniformity of water discharge.

[0072] In some possible embodiments, optionally, Figure 3 and Figure 4 As shown, the connection position between the communicating channel 5 and the first channel 3 is higher than the inner bottom wall surface of the first channel 3 .

[0073] In these embodiments, the inlet of the connecting channel 5 is arranged at the upper end of the first channel 3, and there is a certain height difference between the inlet of the connecting channel 5 and the inner bottom wall of the first channel 3, so that the water needs to fill the first channel 3 for a whole circle before overflowing from the connecting channel 5 and entering the second channel 4, so that the height difference between the inlet of the connecting channel 5 and the inner bottom wall of the first channel 3 can ensure that the water in the first channel 3 can enter the second channel 4 only after reaching a certain water level, and this method does not require an additional switch structure, so that the structure of the water distribution plate 100 is relatively simple. Among them, in this setting, the size of the first preset water level depends on the height difference between the inlet of the connecting channel 5 and the inner bottom wall of the first channel 3.

[0074] Of course, in order to ensure that the water in the first channel 3 can enter the second channel 4 only after reaching a certain water level, a switch structure can also be set at the entrance of the connecting channel 5, and it is required that the switch structure can only be opened after the water in the first channel 3 reaches a first preset water level.

[0075] In any of the above embodiments, optionally, Figure 3 and Figure 4 As shown, the surface of the first channel 3 and the second channel 4 close to one end of the wet curtain 210 is the first inner bottom wall surface, and along the height direction of the wet curtain 210, the first inner bottom wall surface of the second channel 4 is higher than the first inner bottom wall surface of the first channel 3.

[0076] In these embodiments, the inner bottom wall of the second channel 4 is the highest, so that an annular groove can be arranged correspondingly on the outer bottom of the second channel 4 to facilitate the discharge of water from the first drain hole 42. At the same time, this arrangement can also make the inner bottom wall of the first channel 3 lower, so as to ensure that there is a certain height difference between the connecting channel 5 and the inner bottom wall of the first channel 3, thereby ensuring that the water in the first channel 3 can enter the second channel 4 only after reaching a certain water level.

[0077] In some possible embodiments, optionally, Figure 2 As shown, the wet curtain assembly 200 further includes: an upper water hole 2, which is arranged in the first channel 3 to supply water to the first channel 3; or a water supply channel, which is connected to the first channel 3 to supply water to the first channel 3.

[0078] In these embodiments, the wet curtain assembly 200 further includes an upper water hole 2, which is disposed in the first channel 3, and the water to be distributed is transported to the first channel 3 through the upper water hole 2. Alternatively, the wet curtain assembly 200 further includes a water supply channel, which is connected to the first channel 3, and the water to be distributed is transported to the first channel 3 through the water supply channel.

[0079] In some possible embodiments, optionally, Figure 4 As shown, the surface of the disk body 1 close to the wet curtain 210 is the first bottom surface, the portion of the first bottom surface corresponding to the first channel 3 abuts against the top of the wet curtain 210, and a water gap 16 is provided between the portion of the first bottom surface corresponding to the second channel 4 and the top of the wet curtain 210.

[0080] In these embodiments, the portion of the first bottom surface corresponding to the first channel 3 abuts against the top of the wet curtain 210, so that the water diversion tray 100 can be supported by the wet curtain 210. A water gap 16 is provided between the portion of the first bottom surface corresponding to the second channel 4 and the top of the wet curtain 210. The provision of the water gap 16 can ensure the unobstructed drainage of the first drainage hole 42, and prevent the first drainage hole 42 from being abutted and blocked by the wet curtain 210, so that the drainage efficiency can be ensured.

[0081] In some possible embodiments, optionally, Figure 4 As shown, the water gap 16 is formed by the second channel 4 being recessed from the first bottom surface toward the direction away from the wet curtain 210. Or the water gap 16 is formed by the top of the wet curtain 210 being recessed toward the direction away from the water diversion tray 100. Or the portion of the first bottom surface corresponding to the first channel 3 is convexly arranged in the direction close to the wet curtain 210 relative to the portion of the first bottom surface corresponding to the second channel 4, so as to form the water gap 16.

[0082] In some possible embodiments, optionally, Figure 2 and Figure 4 As shown, the wet curtain assembly 200 further includes: a third channel 8, which is arranged on the disc body 1 and is located on one side of the second channel 4 along the radial direction of the disc body 1. Figure 5 and Figure 6 As shown, the third channel 8 is provided with an overflow channel 9 along the circumference of the disk body 1 for connecting the second channel 4 and the third channel 8 when the water level of the second channel 4 reaches a second preset water level.

[0083] In these embodiments, the wet curtain assembly 200 also includes a third channel 8 and an overflow channel 9. The third channel 8 is arranged on the disc body 1, and is located on one side of the second channel 4 along the radial direction of the disc body 1. The third channel 8 is arranged along the circumference of the disc body 1. The overflow channel 9 can connect the second channel 4 and the third channel 8 when the water level of the second channel 4 reaches the second preset water level. In this way, when the water is not discharged in time from the first drain hole 42, the water can enter the third channel 8 from the overflow channel 9 at the top of the second channel 4, and then flow out from the third channel 8, thereby playing a role of drainage through the third channel 8. At the same time, the overflow channel 9 can also ensure that the water flow inside the water distribution tray 1 forms a circulation passage, avoiding the water distribution tray 1 from being too closed inside, forming internal bubbles, and causing the water flow to be unable to circulate normally, thereby ensuring the air pressure balance inside the water distribution tray 1 and avoiding the water backflow in the second channel.

[0084] By setting the second preset water level, the uniformity of the water discharge in the third channel 8 can be ensured, and the concentrated water discharge in the third channel 8 can be ensured. In particular, when the water in the third channel 8 is directly discharged onto the wet curtain 210, the water in the third channel 8 can be evenly distributed in the wet curtain 210 to evenly wet the wet curtain 210.

[0085] There is a height difference between the overflow channel 9 and the inner bottom wall of the second channel 4 , so that water can overflow from the overflow channel 9 only when the third channel 8 reaches a certain water level.

[0086] In some possible embodiments, optionally, Figure 5 and Figure 6As shown, the wet curtain assembly 200 further includes: a second water drop hole 82 disposed in the third channel 8 , and water in the third channel 8 can flow to the wet curtain 210 or the water tank 310 through the second water drop hole 82 .

[0087] In these embodiments, a second drain hole 82 may be provided in the third channel 8, so that when the first drain hole 42 fails to drain water in time, water may enter the third channel 8 from the overflow channel 9 at the top of the second channel 4, and then flow from the second drain hole 82 to the wet curtain 210 or the water tank 310, thereby achieving a drainage effect through the second drain hole 82. At the same time, this arrangement can also recycle the water in the third channel 8, thereby improving the utilization rate of water.

[0088] In some possible embodiments, optionally, Figure 5 and Figure 6 As shown, the surface of the disk body 1 close to the wet curtain 210 is the first bottom surface, and the portion of the first bottom surface corresponding to the third channel 8 abuts against the top of the wet curtain 210 .

[0089] In these embodiments, the portion of the first bottom surface corresponding to the third channel 8 abuts against the wet curtain 210 , and the water diversion tray 100 can be supported by the wet curtain 210 .

[0090] In some possible embodiments, optionally, Figure 2 As shown, a water supply hole 2 is provided in the first channel 3 , and the first channel 3 is arranged along the circumference of the disk body 1 . Along the radial direction of the disk body 1 , the second channel 4 is located between the first channel 3 and the third channel 8 .

[0091] In these embodiments, the upper water hole 2 can be connected to the water tank 310 so that the water in the water tank 310 can be directly transported to the first channel 3. The first channel 3 is arranged in an annular shape along the circumference of the disc body 1, so that the first channel 3 can be evenly distributed along the circumference of the wet curtain 210, so that the uniformity of water discharge can be ensured. By arranging the second channel 4 between the first channel 3 and the third channel 8, it can be ensured that the water in the first channel 3 can flow smoothly into the second channel 4, and it can also be ensured that when the water in the second channel 4 overflows, it can be discharged through the third channel 8.

[0092] In some possible embodiments, optionally, Figure 2 As shown, a recessed portion 32 recessed toward the wet curtain 210 is provided in the first channel 3 , and the upper water hole 2 is provided in the recessed portion 32 .

[0093] In these embodiments, the water in the upper water hole 2 needs to fill the recessed portion 32 before it flows from both circumferential sides of the upper water hole 2 along the circumferential direction of the first channel 3. In this way, the speed of the water flow entering the first channel 3 can be slowed down by the recessed portion 32, so that the water can enter the second channel 4 at a natural flow speed, thereby making the water more evenly distributed on the water distribution plate 100.

[0094] In some possible embodiments, optionally, Figure 2 As shown, the wet curtain assembly 200 further includes: a separation rib 6, which is arranged at the upper water hole 2 and is used to separate the first channel 3 into two parts along the circumferential direction of the disc body 1.

[0095] In this embodiment, a dividing rib 6 is provided at the upper water hole 2, which can divide the first channel 3 into two parts along the circumferential direction, that is, the water of the upper water hole 2 is divided into two branches at the beginning, so that each branch can be controlled separately. This setting directly reduces half of the control variables by dividing the first channel 3 into two water flow channels, so that it is easier to adjust and meet the uniformity of water discharge of multiple first water discharge holes 42.

[0096] At the same time, this scheme can ensure the uniformity of water supply through the structural design of the upper water hole 2, can ensure the uniformity of water distribution time through the position design of the connecting channel 5, and can ensure the uniformity of water distribution through the design of multiple first lower water holes 42. The uniformity of water discharge can be ensured. In this way, through this triple structural design, the uniformity of water flow at each node of the wet curtain assembly 200 is fully ensured, so that the water on the wet curtain 210 can be evenly distributed.

[0097] In some possible embodiments, optionally, Figure 3 and Figure 4 As shown, along the height direction of the wet curtain 210, the inner bottom wall of the second channel 4 has a height difference with the inner bottom wall of the first channel 3, and the height difference is greater than 0 mm and less than or equal to 7 mm. This height difference can effectively prevent the first drain hole 42 from being blocked and can also prevent the water flow from generating noise due to excessive drop.

[0098] In some possible embodiments, the diameter of the first water discharge hole 42 is preferably greater than or equal to 1.5 mm and less than or equal to 5 mm, so as to ensure smooth water discharge and avoid discontinuous water discharge due to excessive water flow.

[0099] In some possible embodiments, the opening width of the communication channel 5 along the circumference of the disk body 1 is optionally greater than or equal to 1 mm and less than or equal to 5 mm, so as to ensure smooth water discharge and avoid discontinuous water discharge caused by excessive water flow.

[0100] In some possible embodiments, optionally, there are multiple communicating channels 5 , and the opening areas of the multiple communicating channels 5 increase from the upstream side to the downstream side of the first channel 3 .

[0101] In these embodiments, for the first channel 3, the position of the connecting channel 5 is different, and the water flow passing through it is different. For example, the connecting channel 5 on the upstream side contacts the water flow first, and the connecting channel 5 on the downstream side contacts the water flow later. Therefore, in order to ensure the uniformity of the water discharge of the connecting channels 5 at the upstream and downstream, the opening size of the connecting channel 5 can be set according to the actual position of the connecting channel 5 to adjust the flow rate of the connecting channel 5 to ensure the uniformity of the water discharge of the connecting channels 5 at different positions. Specifically, the connecting channel 5 on the upstream side can be set smaller, and the connecting channel 5 on the downstream side can be set larger to ensure the uniformity of the water flow entering the second channel 4 through multiple connecting channels 5.

[0102] In some possible embodiments, optionally, Figure 2 As shown, a connecting channel 5 is provided at the midpoint between any two adjacent first water discharge holes 42 .

[0103] In this embodiment, the connecting channel and the first drain holes 42 are arranged in a staggered manner, that is, the connecting channel is arranged between two adjacent first drain holes 42. The staggered connecting channel and the first drain holes 42 prevent the water flowing out of the connecting channel 5 from flowing directly into the first drain holes 42. The water flowing out of the connecting channel 5 flows directly to the side wall of the second channel 4, thereby causing the water flow to turn, thereby achieving the diversion of the water flow, and at the same time making the water flow in the second channel 4 more moderate. Secondly, this arrangement allows one connecting channel 5 to correspond to two first drain holes 42, so that the number of connecting channels 5 is relatively moderate, avoiding the situation where the number of connecting channels 5 is too small, resulting in a slow water inlet speed of the second channel 4, and at the same time, avoiding the situation where the number of connecting channels 5 is too large, resulting in a too rapid water flow, resulting in the first channel 3 losing the effect of buffering impact force.

[0104] In some possible embodiments, optionally, Figure 6 As shown, the surface of the tray body 1 close to the wet curtain 210 is the first bottom surface, and one end of the plurality of first drain holes 42 close to the wet curtain 210 is lower than the portion of the first bottom surface corresponding to the second channel 4 .

[0105] In this embodiment, the surface of the tray body 1 close to the wet curtain 210 is the first bottom surface, and the first bottom surface is the lower surface of the tray body 1. One end of the plurality of first drain holes 42 close to the wet curtain 210 is lower than the portion of the first bottom surface corresponding to the second channel 4. That is, the first drain holes 42 extend toward the wet curtain 210 and protrude from the bottom of the second channel 4. This arrangement allows the water discharged from the first drain holes 42 to fall directly, rather than being easy to flow along the lower surface of the tray body 1.

[0106] In some possible embodiments, optionally, Figure 1 As shown, the tray body 1 includes: a chassis 12; an upper cover 14, which is installed on the chassis 12 to cover the chassis 12; wherein the first drain hole 42 is arranged on the chassis 12, and the first channel 3, the second channel 4 and the connecting channel 5 are surrounded by the chassis 12 and the upper cover 14.

[0107] In this embodiment, the tray body 1 is surrounded by a bottom plate 12 and an upper cover 14, so that a relatively closed water passage can be formed to prevent water from being exposed to the air. In order to enclose the first passage 3, the second passage 4 and the connecting passage 5, a groove can be provided on the inner side of the bottom plate 12 or the upper cover 14, and then the first passage 3, the second passage 4 and the connecting passage 5 are formed by the enclosure of the bottom plate 12 and the upper cover 14. Of course, grooves can also be provided on the inner sides of the bottom plate 12 and the upper cover 14 at the same time to form the first passage 3, the second passage 4 and the connecting passage 5.

[0108] In some possible embodiments, optionally, Figure 2 , Figure 3 and Figure 4 As shown, the wet curtain assembly 200 further includes: a first retaining rib 72, which is arranged on the chassis 12 and is arranged in a ring shape along the circumference of the chassis 12; a second retaining rib 74, which is arranged on the chassis 12 and is arranged in a ring shape along the circumference of the chassis 12, and the second retaining rib 74 is arranged on the outer side of the first retaining rib 72 along the radial direction of the chassis 12; a third retaining rib 76, which is arranged on the chassis 12 and is arranged in a ring shape along the circumference of the chassis 12, and the third retaining rib 76 is arranged on the outer side of the second retaining rib 74 along the radial direction of the chassis 12; a fourth retaining rib 78, It is arranged on the chassis 12, and is arranged in a ring shape along the circumference of the chassis 12, and along the radial direction of the chassis 12, the fourth barrier rib 78 is located on the outside of the third barrier rib 76; wherein, the first channel 3 is surrounded by the chassis 12, the upper cover 14, the first barrier rib 72 and the second barrier rib 74, the second channel 4 is surrounded by the chassis 12, the upper cover 14, the second barrier rib 74 and the third barrier rib 76, the chassis 12, the upper cover 14, the fourth barrier rib 78 and the third barrier rib 76 surround the third channel 8, and the connecting channel 5 is a gap arranged in the second barrier rib 74.

[0109] In this embodiment, the wet curtain assembly 200 also includes: a first barrier rib 72, a second barrier rib 74, a third barrier rib 76 and a fourth barrier rib 78, wherein the first barrier rib 72, the second barrier rib 74 and the third barrier rib 76 are arranged in a ring shape along the circumference of the disc body 1. The second barrier rib 74 is arranged on the outside of the first barrier rib 72 along the radial direction of the disc body 1. The third barrier rib 76 is arranged on the outside of the first barrier rib 72 along the radial direction of the disc body 1. The fourth barrier rib 78 is an annular barrier rib and is arranged on the outermost side. In other words, the four barrier ribs enclose three channels in sequence from the inside to the outside. With this arrangement, the required channels can be quickly and conveniently formed on the disc body 1 through the four barrier ribs, thereby facilitating the processing of the disc body 1 and reducing the cost of the disc body 1. At the same time, a notch can be set on the second barrier rib 74 to form a connecting channel 5 to achieve the connection between the first channel 3 and the second channel 4.

[0110] In any of the above embodiments, optionally, a gap is provided between the third barrier rib 76 and the upper cover 14 along the height direction of the wet curtain 210 .

[0111] In this embodiment, the gas and water in the second channel 4 can flow into the third channel 8 through the gap, that is, an overflow channel 9 can be formed through the gap.

[0112] In any of the above embodiments, optionally, Figure 1 As shown, the wet curtain assembly 200 also includes: an upper water pipe 220, which is installed on the wet curtain 210, one end of the upper water pipe 220 is connected to the upper water hole 2, and the other end of the upper water pipe 220 is connected to the water tank 310 of the air conditioning device 300; a lower cover 230, which is installed at the bottom of the wet curtain 210, and a water inlet channel 231 is provided on the lower cover 230, and the water inlet channel 231 is connected to the upper water pipe 220; a sealing member 240 is arranged in the water inlet channel 231, and is used to seal the gap between the water inlet channel 231 and the water supply pipe of the air conditioning device 300.

[0113] In this embodiment, the upper water pipe 220 is used to transport water from the water tank 310 to the upper water hole 2 of the water distribution plate 100. The lower cover 230 is used to support and install the wet curtain 210, and realize the connection between the upper water pipe 220 and the water tank 310 through the water inlet channel 231. The sealing member 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.

[0114] The sealing member 240 is a silicone member.

[0115] Furthermore, the disk body 1 is also provided with a through hole 10 for passing air, wherein one or more of the first channel 3 , the second channel 4 and the third channel 8 are arranged around the through hole 10 in a ring shape.

[0116] like Figure 5As shown, an embodiment of the second aspect of the present application proposes an air conditioning device 300, including a wet curtain assembly 200 provided by any embodiment of the first aspect; the air conditioning device 300 includes at least one of a humidifier, an air purifier and a water-cooled fan.

[0117] According to the air conditioning device 300 proposed in the embodiment of the present application, since it includes the wet curtain assembly 200 provided by any embodiment of the first aspect, the air conditioning device 300 has all the beneficial effects of the wet curtain assembly 200 provided by any embodiment of the first aspect, which will not be repeated here.

[0118] The air conditioning device 300 may specifically be a humidifier, an air purifier with a humidification function, or a water-cooled fan.

[0119] In any of the above embodiments, the humidifier may further include a water tank 310 and a water pump, and the water pump is used to transport the water in the water tank 310 to the water diversion tray 100. The water diversion tray 100 is provided with an upper water hole 2, and a dividing rib 6 is provided at the upper water hole 2. The dividing rib 6 can divide the first channel 3 into two parts along the circumferential direction, so that the water in the upper water hole 2 is divided into two branches at the beginning, so that each branch can be controlled separately. At the same time, a recessed portion 32 recessed in the direction of the wet curtain 210 is provided in the first channel 3 of the water diversion tray 100, and the upper water hole 2 is provided in the recessed portion 32. Furthermore, the first channel 3 and the second channel 4 of the water diversion tray 100 are connected through a connecting channel 5, and the connecting channel 5 connects the first channel 3 and the second channel 4 only when the water level in the first channel 3 reaches the first preset water level. Furthermore, a height difference is provided between the connection point between the connecting channel 5 and the first channel 3 and the inner bottom wall of the first channel 3, so that the water in the first channel 3 can enter the second channel 4 from the connecting channel 5 only when the water level reaches a certain level (i.e., the first preset water level).

[0120] In this arrangement, water will enter the second channel 4 only after the first channel 3 is filled with a certain amount of water along the entire circumferential direction, and then flow from the first water outlet holes 42 of the second channel 4 to the wet curtain 210. Furthermore, the second channel 4 of the water distribution plate 100 is provided with uniformly distributed first water outlet holes 42, so that the water in the second channel 4 can flow evenly to the wet curtain 210. This humidifier directly reduces half of the control variables by dividing the first channel 3 into two water flow channels, so that it is easier to adjust and meet the uniformity of water discharge of multiple first water outlet holes 42. The design of the recessed portion 32 is that the water in the upper water hole 2 needs to fill the recessed portion 32 before it flows along the circumference of the first channel 3 from both sides of the upper water hole 2, so that the speed of the water flow entering the first channel 3 can be slowed down by the recessed portion 32, so that the water can enter the second channel 4 at a natural flow speed, so that the water can be more evenly distributed on the water distribution plate 100. By designing the position of the connecting channel 5, a height difference can be set between the connection between the connecting channel 5 and the first channel 3 and the inner bottom wall of the first channel 3. In this way, only after the first channel 3 is filled with a certain amount of water along the entire circumferential direction, the water will enter the second channel 4, and then flow from the first water discharge hole of the second channel 4 to the wet curtain 210. In this way, the water in the first channel 3 can basically flow into the second channel 4 synchronously, and then flow to the wet curtain synchronously, so as to ensure the uniformity of water discharge, so that each position of the wet curtain is basically in contact with water at the same time, so as to ensure that the wet curtain is evenly wetted, and avoid the situation that some positions of the wet curtain are first in contact with water to be fully moistened, while some positions are still dry. This type of humidifier has been structurally designed in each link from water supply to water distribution to water discharge. The structural design at the water supply hole 2 can ensure the uniformity of water supply. The position design of the connecting channel 5 can form a height difference, so that only after the first channel 3 is filled with a certain amount of water along the entire circumferential direction, the water will enter the second channel 4, and then flow from the first water discharge hole 42 of the second channel 4 to the wet curtain 210, so as to ensure the uniformity of water distribution time, thereby ensuring the uniformity of water distribution. The design of multiple first water discharge holes 42 can ensure the uniformity of water discharge. Therefore, through this triple structural design, the uniformity of water flow at each node of the wet curtain assembly 200 is fully ensured, so that the water on the wet curtain 210 can be evenly distributed.

[0121] The following introduces a humidifier and the wet curtain assembly used therein.

[0122] In the related scheme, the common evaporative humidifier drives the air around the wind wheel inside the fuselage to form a negative pressure by rotating the centrifugal wind wheel on the top of the fuselage, thereby driving the air around the bottom of the fuselage to circulate into the interior of the fuselage, passing through the wet curtain assembly, and finally flowing out through the top air outlet of the fuselage; the wet curtain material around the wet curtain assembly has a high water absorption characteristic, and the water flowing out from the water flow hole on the top of the wet curtain due to gravity and the water absorption characteristic of the wet curtain material itself will cause the water flow to spread evenly around the wet curtain assembly and continuously soak the wet curtain. The wet curtain assembly is surrounded by moist water molecules. When the dry air flows around the wet curtain assembly, it will take away the water molecules on the wet curtain assembly to achieve the purpose of humidifying the air. The air is constantly circulating, and the water from the water outlet on the top of the wet curtain is also constantly flowing down. The wet curtain itself is also constantly being soaked, thereby achieving the purpose of continuously humidifying the air. The shortcomings of this humidifier during use are as follows: the ideal state of the wet curtain assembly is to ensure that the water transported from the water pipe by the water pump of the fuselage is completely and evenly distributed to all parts of the wet curtain. There is only one water hole, which is generally a circular hole with a diameter of 6mm-12mm. The wet curtain is a circle. How to ensure that the water transported from a small hole is evenly distributed to the entire circle of the wet curtain is a difficult point. If the water flow cannot be evenly distributed, some places around the wet curtain will be very wet, some places will be dry, or some places will not be thoroughly moistened, which will greatly affect the humidification performance.

[0123] In order to solve the above problems, this embodiment proposes a wet curtain assembly, such as Figures 1 to 3 As shown, the wet curtain assembly specifically includes:

[0124] The wet curtain upper cover (i.e., the upper cover 14) forms a closed sealing structure together with the wet curtain fixed cover, and the top surface is the top appearance surface of the entire wet curtain 210; at the same time, the special structure is used to initially divide the water coming from the water inlet pipe into two equal parts.

[0125] Wet curtain fixed cover (i.e. chassis 12): the main component for water circulation and diversion, together with the wet curtain upper cover, forms a circulation sealing structure; mainly forms two water flow channels, and the uniformity of water discharge is met by adjusting the overflow gate between the water flow channels.

[0126] Wet curtain 210: The top and bottom are fixed to the wet curtain fixed cover and the wet curtain lower cover (i.e., lower cover 230) by glue respectively. At the same time, water flowing out from the specific water outlet holes of the wet curtain fixed cover soaks the wet curtain 210, and humidifies the surrounding environment through the flow of air.

[0127] Upper water pipe 220: It is installed between the wet curtain fixed cover and the wet curtain lower cover by cooperating with the bottom silicone parts. It passes through the area of ​​the wet curtain 210, and the wet curtain 210 needs to be specially made to avoid the gap. It mainly completes the water transported up by the water pump from the bottom of the fuselage and transports it to the top of the wet curtain 210.

[0128] The lower cover of the wet curtain (i.e., the lower cover 230) mainly supports the bottom of the wet curtain 210, and fixes the bottom of the wet curtain 210 by gluing it in contact with the bottom of the wet curtain 210. At the same time, a water leakage hole is opened on the lower cover of the wet curtain, and excess water falling from the wet curtain 210 flows through the water leakage pipe of the lower cover of the wet curtain and flows back to the water tank 310 of the machine.

[0129] Silicone parts: mainly through the deformable compression characteristics of silicone parts, the entire wet curtain assembly 200 is connected to the upper water hole 2 of the machine body through the silicone parts, and it is ensured that water flows upward through the upper water pipe 220.

[0130] In this embodiment, the water flow is first fully diverted through the water diverter ribs at the water hole 2 on the wet curtain fixed cover, and the water flow is evenly divided into two parts, each responsible for the drainage of the 180° area around the wet curtain 210. The water diverter ribs (separating ribs 6) need to go deep into the upper water hole 2, and the water diversion must be completed before the water in the upper water pipe 220 reaches the wet curtain fixed cover. The water diverter ribs are simply structural reinforcements at the water holes of the wet curtain fixed cover, and are not separate components; the presence of the water diverter ribs will increase the resistance at the upper water hole 2, which is generally applicable to larger upper water hole diameters (the inner diameter of the upper water pipe 220 is 8mm-15mm). For too thin upper water holes 2, it is not necessary to add them, and the water coming up from the upper water hole 2 can be naturally diverted.

[0131] The water flow channel on the wet curtain fixed cover is mainly divided into two parts. The water flow channel around the first lower water hole 42 is the second channel 4, and the water flow channel around the inner circle connected to the upper water hole 2 is the first channel 3. The water level of the first channel 3 is lower than that of the second channel 4. Generally, the water level difference is between 0mm-7mm.

[0132] Assume that there are N first drain holes 42 in the second channel 4, and N is generally an even number (the cylindrical wet curtain is symmetrical about the plane formed by the center of the upper water hole 2 and the central axis of the wet curtain 210, so the first drain holes 42 in the second channel 4 should also be bilaterally symmetrical, and the number of holes is an even number).

[0133] The aperture is adjusted to be consistent (in order to ensure that the variables are as small as possible, the aperture of the first drain hole 42 of the second channel 4 is set to a uniform value, and the amount of water flow is adjusted by the size of the gap at the gate), which is generally between 1.5mm-5mm. Figure 2 As shown, according to the principle that one sluice gate is responsible for two first drain holes 42 , there should be N / 2 gates between the first channel 3 and the second channel 4 .

[0134] like Figure 2As shown, the two first downholes 42 are supplied with water through a gate connected to the channel. Generally, the opening width of the gate is between 1mm and 5mm. The gate is close to the upper water hole 2, and the water flow is relatively large. Compared with the gate at the rear of the flow path, the gate width is smaller, and the width becomes larger as it goes to the rear. At the same time, the water supplied by the gate to the first downhole 42 that has not flowed out will continue to be supplied to the subsequent first downhole 42 through the second channel 4. One gate is responsible for the two first downholes 42. The whole is symmetrical.

[0135] In order to solve the problem of uniformity of water discharge from the wet curtain 210, the water distribution tray 100 of the present embodiment has evenly divided the water flow into two parts from the position of the upper water hole 2 of the wet curtain 210 cover, each of which is responsible for the uniformity of water discharge within a range of 180 degrees. At the same time, the discharge component is divided into two inner and outer water flow paths, namely the first channel 3 and the second channel 4. The water flow of the second channel 4 mainly flows in through the first channel 3. Under the condition that the apertures of the plurality of first discharge holes 42 of the second channel 4 are ensured to be consistent, the discharge of water in the second channel 4 is uniform by adjusting the size of the connecting gate on the connecting channel between the first channel 3 and the second channel 4. One gate is responsible for the discharge of water from at least two first discharge holes 42, that is, N connecting valves only need N / 2 gates at most, and the original need to adjust the apertures of N holes to discharge water uniformly is changed to only need to adjust the size of N / 2 gates to meet the uniform discharge, thereby reducing the control variables. The fewer the variables, the closer to the theoretical discharge uniformity.

[0136] This embodiment can achieve the following beneficial effects:

[0137] 1. By dividing the water flow channels into two, the control variables are directly reduced by half, making it easier to adjust and meet the uniformity of water discharge.

[0138] 2. The water flow in the second channel 4 mainly comes from the overflow of the gate of the first channel 3. During the inflow process, the direction of the water flow is changed by 90 degrees, which greatly eliminates the impact force of the water just flowing out of the upper water pipe 220. The first water discharge holes 42 in a circle simply rely on gravity to discharge water, which reduces the influence of the impact force of the water flow on the water discharge through the holes and makes it easier to adjust the discharge.
