[0040] Unless otherwise defined, all terms (including technical terms and scientific terms) used in the description of this embodiment have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0041] In the prior art, the main function of the water tray of the air conditioning equipment is to collect the condensed water generated during the operation of the air conditioning equipment to prevent the condensed water from overflowing. The water tray is usually arranged on the upper part of the water tank and seals the water tank. The water tray completely carries and guides the condensed water flowing down the evaporator of the air conditioning equipment, and also acts as a water tank cover to prevent the condensed water in the water tank from overflowing.

[0042] The general design of the water tray takes the convenience of drainage into consideration, and a water guide groove is set on the surface of the water tray to guide the condensed water to a specific outlet or drainage point to ensure that the condensed water can flow in an orderly manner to avoid water accumulation or leakage. Due to the large diameter of the water tray, an overflow port is also required to open when the water in the water tray exceeds a certain limit, allowing excess water to flow out and preventing water from overflowing the water tray.

[0043] The drainage device of this air conditioning equipment has a complex structure, and the water tray and the drainage point are generally suspended and far apart, which results in a large drop difference. Condensed water will directly fall to the bottom of the water tray, producing a loud dripping sound, causing noise and affecting the user experience.

[0044] In view of the above problems, the embodiments of the present invention provide a drain pipe 100 and an air conditioning device 1000 that overcome the above problems or at least partially solve the above problems, which can effectively reduce the drop difference of dripping water from the air conditioning device 1000 to the drain pipe, reduce the noise of dripping water, and enhance the user experience.

[0045] Figure 1 is a schematic structural diagram of a drain pipe 100 according to an embodiment of the utility model. Figure 2 yes Figure 1 A schematic enlarged diagram of point A is shown. Figure 3 It is a schematic top view of a drain pipe 100 according to an embodiment of the present utility model.

[0046] like Figure 1-Figure 3 As shown, the drain pipe 100 of the air conditioning device 1000 includes a water receiving tray 10 and a pipe body 20. The water receiving tray 10 includes a bottom wall 11 and a peripheral wall 12 extending upward from the periphery of the bottom wall 11, the bottom wall 11 is formed with a water receiving protrusion 13 protruding upward, and the water receiving tray 10 is also provided with at least one water leakage hole 14. The pipe body 20 is connected to the bottom of the water receiving tray 10 to allow water drops flowing down from the top of the water receiving tray 10 to fall on the water receiving protrusion 13, flow downward along its surface, and enter the pipe body 20 through the water leakage hole 14 to reduce water flow noise.

[0047] Here, it can be understood that when the air conditioning device 1000 performs a dehumidification operation, the water vapor in the air is condensed into liquid water, and then the water is discharged from the drain port or drainage device of the air conditioning device 1000. The bottom wall 11 of the water receiving tray 10 and the peripheral wall 12 extending upward from the periphery of the bottom wall 11 define a space for receiving water flowing down from above. Since the bottom wall 11 of the water receiving tray 10 is not a plane, water will not drip directly to the bottom of the water receiving tray 10, but will fall to the upwardly protruding water receiving protrusion 13 formed on the bottom wall 11.

[0048] The embodiment of the utility model is provided with a water receiving protrusion 13 protruding upward on the bottom wall 11 of the water receiving tray. The water receiving protrusion 13 can effectively buffer the dripping water, and prevent the water from directly "hitting" the bottom of the water receiving tray 10 to generate a large noise. Moreover, the water receiving protrusion 13 can also effectively reduce the falling distance of water dripping from the drainage of the air conditioning equipment 1000 to the water receiving tray 10. The water droplets are dispersed into small water droplets at the water receiving protrusion 13, and further dispersed in the pipe body 20, further reducing the noise generated when dripping water, and improving the user experience.

[0049] In some embodiments, the water receiving protrusion 13 is truncated cone-shaped as a whole, and includes a top surface 131 and a truncated cone surface 132 extending downwardly from the edge of the top surface. Here, the top surface 131 of the water receiving protrusion 13 is a circular plane, and the truncated cone surface 132 is an inclined side surface. When the water receiving tray 10 receives water dripping from above, the water falls to the top surface 131 of the water receiving protrusion 13 or the truncated cone surface 132 of the water receiving protrusion 13. The edge of the top surface 131 is chamfered, which is conducive to the water dripping to the top surface 131 being dispersed into small water droplets at the top surface 131 and then flowing to the truncated cone surface 132 along the chamfer.

[0050] The truncated cone surface 132 is inclined relative to the axis line of the water receiving protrusion 13 and forms an acute angle with the vertical direction of water dripping. The water receiving protrusion 13 can effectively buffer the dripping water to prevent the water from directly "hitting" the bottom of the water receiving tray to generate a large noise. The flow speed of the water droplets at the truncated cone surface 112 is slowed down, which is beneficial to reduce the sound of water dripping onto the water receiving tray 10.

[0051] The diameter of a general water tray is relatively large, and a certain amount of water is usually accumulated before being discharged to prevent the water from overflowing and causing adverse effects on the surrounding environment or equipment. However, the bottom of the water tray 10 in the utility model is provided with a water receiving protrusion 13 that protrudes upward, and water drops are dispersed into small water drops as quickly as possible at the water receiving protrusion 13. After the water drops fall onto the water receiving protrusion 13, they slide directly along the inclined surface of the water receiving protrusion 13. The sound of the small water drops flowing on the side of the water receiving protrusion 13 is small, and then the water tray 10 is quickly discharged through the water leakage hole 14, ensuring that the water can flow out smoothly and avoiding water accumulation in the water tray 10.

[0052] In some embodiments, the truncated cone surface 132 is slightly raised toward the outside of the water receiving tray 10. Specifically, the truncated cone-shaped peripheral surface 112 of the water receiving protrusion 13 is slightly raised upward, which can guide the dripping water to a certain extent and is also conducive to further buffering the dripping water.

[0053] In some embodiments, the water receiving protrusion 13 is located at the center of the water receiving tray 10, and a circular groove 15 extending along the outer periphery of the water receiving protrusion 13 is formed with the peripheral wall 12, and each water leakage hole 14 is opened at the circular groove 15. Here, the water receiving tray 10 is a disc-shaped as a whole, and the water receiving protrusion 13 is located at the middle position of the water receiving tray 10, so that the water drops discharged from the air conditioning device 1000 above the water receiving tray 10 fall on the water receiving protrusion 13, so that the water is dispersed and buffered at the water receiving protrusion 13.

[0054] The water receiving protrusion 13 and the peripheral wall 12 of the water receiving tray portion 10 form a circular groove 15 extending along the outer peripheral edge of the water receiving protrusion 13. After water drops onto the water receiving protrusion 13, it flows downward along the surface of the water receiving protrusion 13. Part of the water flows directly from the leakage hole 14 to the pipe body 20, and another part of the water flows to the groove 15. The groove 15 can temporarily store water discharged from the air conditioning equipment 1000 to prevent dripping water from splashing out of the water receiving tray portion 10.

[0055] In some embodiments, the water leakage hole 14 is provided at the circular groove 15, and after the water drips onto the water receiving protrusion 13, it flows downward along the surface of the water receiving protrusion 13 to the bottom of the water receiving protrusion 13, and then enters the pipe body 20 from the water leakage hole 14 on the circular groove 15. In other embodiments, the water leakage hole 14 can also be provided on the bottom of the truncated cone surface 132. Regardless of whether the water leakage hole 14 is located on the truncated cone surface 132 or on the groove 15, when the water flowing from the inclined side of the water receiving protrusion 13 into the groove 15 gathers to a certain amount of water, it can easily flow out of the water receiving tray 10 from the water leakage hole 14.

[0056] In some embodiments, the diameter of the water receiving tray portion 10 is small, the distance between the outer periphery of the water receiving protrusion 13 and the peripheral wall 12 of the water receiving tray portion 10 is small, and the groove 15 formed by the peripheral wall 12 and the outer periphery of the water receiving protrusion 13 is narrow. The dripping water is not easy to accumulate on the water receiving tray portion 10, and it is easy to reach the leakage hole 14 at the groove 15 through the inclined truncated cone surface 132, and flow out of the water receiving tray portion 10 from the leakage hole 14.

[0057] The provision of the water leakage hole 14 at the groove 15 can prevent water from being retained on the water receiving tray 10. The retained dripping water may breed bacteria, mold and other microorganisms, posing a potential threat to the indoor environment and the health of users. Through the water leakage hole 14, the dripping water can quickly flow out of the water receiving tray 10, reducing the retention time and reducing the risk of retention. The provision of the water leakage hole 14 is also conducive to reducing the odor caused by the retention of dripping water, keeping the water receiving tray 10 dry and clean, and improving the indoor air quality.

[0058] The pipe body 20 is connected to the bottom of the water receiving tray 10, and the inner wall of the pipe body 20 is connected to the leakage hole 14. The leakage hole 14 is arranged at the groove 15, so that the distance between the leakage hole 14 and the inner wall of the pipe body 20 can be made smaller, ensuring that the dripping water at the leakage hole 14 will not splash and drip in the air due to the large distance between the leakage hole 14 and the inner wall of the pipe body 20.

[0059] In some embodiments, the peripheral wall 12 includes a vertical section 121 and a gradually expanding section 122, wherein the vertical section 121 extends upward from the outer peripheral edge of the bottom wall 11 in a vertical direction, and the gradually expanding section 122 extends upward and gradually radially outward from the upper edge of the vertical section 121. Here, the vertical section 121 and the gradually expanding section 122 are relative to the inner wall of the water receiving tray 10. When the dripping water falls on the water receiving protrusion 13 and splashes, it will splash to the gradually expanding section 122, and the gradually expanding section 122 plays a role in guiding the splashed water, so that the water droplets splashed on the peripheral wall 12 can flow downward along the gradually expanding section 122, and the water is not easy to accumulate on the water receiving tray 10, and the water can be effectively drained.

[0060] In addition, compared to setting the entire peripheral wall 12 as a vertical section 121, adding a gradually expanding section 122 that gradually extends outward at an angle can increase the diameter of the top of the water receiving tray portion 10 and increase the surface area for collecting water, so that water flowing to the water receiving tray portion 10 is not easy to drip to the outside of the water receiving tray portion 10, which is beneficial for the water receiving tray portion 10 to collect water.

[0061] Figure 4 is a schematic assembly diagram of a mounting member 300 and a drain pipe 100 according to an embodiment of the utility model. Figure 5 yes Figure 4 A schematic cross-sectional view of the drain pipe 100 is shown. Figure 6 is a schematic assembly diagram of a water tank 200 and a drain pipe 100 according to an embodiment of the utility model. Figure 5 The median distance B is the pitch of a single helix.

[0062] In some embodiments, Figure 4-Figure 6 As shown, at least one water guide groove 21 is provided on the inner wall of the pipe body 20, and the water inlet end of each water guide groove 21 is connected to a water leakage hole 14, so as to allow water flowing out of the water leakage hole 14 to enter the water guide groove 21, and be guided downward by the water guide groove 21 to buffer its downward flow speed and reduce flow noise. Specifically, after the air conditioning device 1000 runs the dehumidification operation, the water vapor is condensed into liquid water, and the water falls to the water receiving tray 10 in the vertical direction under the action of its own gravity, and flows from the water leakage hole 14 at the bottom end of the water receiving tray 10 to the water inlet end of the water guide groove 21 in the pipe body 20, and then flows down along the water guide groove 21.

[0063] A groove-shaped water-guiding structure is provided in the tube body 20, which can effectively guide water so that water slides down along the water-guiding groove 21. Water droplets are not likely to splash directly from the inner wall of the tube body 20, and the water droplets will not flow disorderly but merge into large water droplets on the inner wall of the tube body 20, thereby effectively reducing the dripping sound of water droplets.

[0064] The groove-shaped water guide groove 21 can also increase the surface area of ​​contact between water droplets and the pipe body 20, can effectively bear the pressure in the pipe body 20, and improve the pressure resistance of the pipe body 20 of the drain pipe 100. The design of setting the water guide groove 21 on the inner wall of the pipe body 20 is also conducive to improving the water guiding function of the pipe body 20, greatly improving the drainage efficiency, and effectively avoiding the problem of odor and impurity precipitation caused by water retention in the pipe body 20, so that the drain pipe 100 can run smoothly.

[0065] In some embodiments, the surface of the water guide groove 21 is designed to be smooth and flat, so that it is easy to clean, and can be made of materials such as stainless steel and ceramics, which have strong corrosion resistance and are not easy to adhere to stains, making the cleaning of the pipe body 20 more convenient. In addition, the simple design also reduces the blind spot of cleaning and further improves the cleaning efficiency.

[0066] In some embodiments, water on the inner wall of the tube body 20 flows out of the tube body 20 and then flows into the water tank 200, which is located below the bottom of the tube body 20. In a preferred embodiment, the bottom of the tube body 20 contacts the bottom of the water tank 200, and water flows directly from the bottom end of the tube body 20 into the bottom of the water tank 200 to avoid noise.

[0067] In some embodiments, the bottom of the water tank 200 is configured as a smooth surface, so that the water falling from the water guide groove 21 contacts the bottom of the water tank 200 in a relatively stable manner, producing a softer sound.

[0068] In some embodiments, a mounting member 300 connected to the pipe body 20 is provided at the outer wall of the pipe body 20, and the mounting member 300 has at least one clamping portion 310, and the clamping portion 310 is used to clamp with the water tank 200 of the air conditioning device 1000, so as to install the drain pipe 100 on the water tank 200. Figure 6 An installation position is provided in the water tank 200, the drain pipe 100 is located on the installation position, and the clamping portion 310 is clamped on the top of the installation position.

[0069] In some embodiments, the water receiving tray 10 is different from a general water tray. The water receiving tray 10 has a smaller diameter and does not completely cover the top of the water tank 200, which can save costs. The upwardly protruding water receiving protrusion 13 formed on the bottom wall 11 of the water receiving tray 10 is located below the drainage of the air conditioning device 1000. At least one water leakage hole 14 is provided at the outer periphery of the water receiving protrusion 13, which can quickly drain the water dripping from the drainage into the pipe body 20 and the water tank 200.

[0070] In some embodiments, the number of the clamping parts 310 is set to 3. In other embodiments, the number of the clamping parts 310 can be set according to actual needs, such as 1, 2, 4, or 5. Increasing the number of the clamping parts 310 can improve the stability of the drain pipe 100 installed on the water tank 200 of the air conditioning device 1000.

[0071] The clamping method can effectively connect and fix the drain pipe 100 and the water tank 200, ensuring the stability between the drain pipe 100 and the water tank 200. Compared with the traditional welding connection method, the clamping method does not require the use of high-temperature welding equipment, reducing production costs and installation difficulty.

[0072] The drain pipe 100 is connected to the water tank 200 by the mounting member 300. This connection method is relatively simple, does not require tedious preparation work and waiting time, improves construction efficiency, and saves time cost. In some other embodiments, the drain pipe 100 and the water tank 200 are an integrally formed structure. The drain pipe 100 and the water tank 200 are integrally formed, which can significantly improve production efficiency. Since the entire manufacturing process can be completed in a short time, the waiting and conversion time for installation are reduced, thereby improving the practicality of the drain pipe 100.

[0073] In some embodiments, each water guide groove 21 extends in a spiral shape in the direction from the water inlet end to the water outlet end of the pipe body 20 in the length direction. Here, the pipe body 20 is arranged vertically, the water inlet end of the pipe body 20 is connected to the bottom of the water receiving tray 10 and communicated with the water leakage hole 14, and the water outlet end of the pipe body 20 is located at the bottom end of the pipe body 20.

[0074] The interaction force of the molecules inside the water droplets forms surface tension near the surface of the water droplets, making the surface of the water droplets present a certain elasticity. When the water droplets contact the water guide groove 21, the surface tension will make the water droplets maintain their integrity as much as possible and form a relatively stable shape. Gravity is the force of the earth that attracts objects downward, which enables the water droplets to fall vertically downward even when not affected by other forces.

[0075] In some embodiments, the tube body 20 is arranged vertically, and water drops with a relatively stable shape can fall along the water guide groove 21 under the action of their own gravity. The water guide groove 21 has a certain degree of roughness, which can reduce the kinetic energy of the water droplet flow. The water guide groove 21 extends in a spiral shape, which can lengthen the flow path of the water droplet in the tube body 20, reduce the kinetic energy of the water droplet flowing out of the water outlet end of the water guide groove 21, make the water droplet fall gently to the bottom of the water tank 200, and reduce the sound of the water droplet falling to the water tank 200. In other embodiments, the inclination angle of the tube body 20 can be set according to actual needs.

[0076] The spiral water guide groove 21 is conducive to the flow of water droplets along a certain trajectory, preventing water from splashing when falling in the pipe body 20, which is conducive to improving the drainage stability of the pipe body 20. It can also prevent water droplets from gathering into large droplets in the pipe body 20, reduce the risk of fatigue damage caused by stress concentration in the working process of the pipe body 20, and increase the service life of the drainage pipe 100.

[0077] The spiral water guide groove 21 can effectively disperse the small water droplets dispersed on the surface of the water receiving protrusion 13 again, so that the small water droplets become smaller in size. In this way, the volume of water is smaller when it enters the water tank 200 after exiting the drain pipe 100, reducing the sound made when the water drops fall to the bottom of the water tank 200.

[0078] In some embodiments, each water guide groove 21 extends from the water inlet end to the water outlet end of the tube body 20. Here, the water inlet end and the water outlet end of the water guide groove 21 are consistent with the water inlet end and the water outlet end of the tube body 20. It can be understood that the length of each water guide groove 21 along the tube body 20 is the length of the tube body 20. In this way, the water flowing down from the water leakage hole 14 flows out of the tube body 20 along the water guide groove 21, which can effectively guide the water flow and reduce the sound of water flowing in the tube body 20.

[0079] In some embodiments, the number of water guide grooves 21 and water leakage holes 14 are both multiple and arranged in one-to-one correspondence, the multiple water guide grooves 21 are evenly distributed along the circumference of the tube body 20 and have the same spiral direction, and the multiple water leakage holes 14 are evenly distributed along the circumference of the water receiving protrusion 13. Specifically, the bottom of the water receiving tray 10 and the bottom of the water receiving protrusion 13 are both circular, the multiple water leakage holes 14 are evenly arranged along the outer periphery of the water receiving protrusion 13, and the water inlet ends of the multiple water guide grooves 21 are arranged corresponding to the water leakage holes 14.

[0080] In some embodiments, the number of the water leakage holes 14 is set to two, and the two water leakage holes 14 are evenly distributed at the bottom end of the curved surface of the water receiving protrusion 13, and the connecting line formed by the two water leakage holes 14 is consistent with the center line of the water receiving protrusion 13. In other embodiments, the number of the water leakage holes 14 can be set according to actual needs, such as 3, 4, 5, or 6.

[0081] When the working drainage volume of the air conditioning equipment 1000 is large, more leakage holes 14 can be set so that the water discharged from the air conditioning equipment 1000 and flowing to the drain pipe 100 can enter the pipe body 20 more quickly through the leakage holes 14 at the bottom end of the water receiving tray 10, which is beneficial to improving the drainage efficiency of the drain pipe 100.

[0082] In some embodiments, there are multiple water guide grooves 21, and each water guide groove 21 corresponds to a water leakage hole 14. Specifically, after water drops are discharged from the air conditioning device 1000 and drip onto the water receiving protrusion 13, they flow to the truncated cone surface 132 of the water receiving protrusion 13, the water leakage hole 14 of the water receiving protrusion 13, and the water guide groove 21 in sequence. Water can flow from multiple water leakage holes 14 to different water guide grooves 21, thereby improving the drainage capacity of the drain pipe 100.

[0083] Each water guide groove 21 corresponds to a water leakage hole 14, and each water leakage hole 14 can be drained independently, which reduces the problem of poor drainage caused by blockage when multiple water guide grooves 21 share one water leakage hole 14, making drainage smoother. In this way, the water on the water receiving tray 10 can be quickly drained away, and the drainage efficiency of the drainage pipe 100 can be improved. This design can ensure that the drainage pipe 100 can handle a large amount of water flow in a timely and effective manner.

[0084] Each water guide groove 21 corresponds to a water leakage hole 14, which makes maintenance and inspection work more convenient. When a water guide groove 21 has a problem, the corresponding water leakage hole 14 can be quickly located and targeted maintenance can be carried out without inspecting and repairing the entire drain pipe 100. This can also make the drain pipe 100 more stable and reliable. Even if a drainage groove or a water leakage hole 14 has a problem, it will not cause a serious impact on the entire drain pipe 100, reducing the risk of failure of the drain pipe 100.

[0085] In some embodiments, the number of the water guide grooves 21 and the number of the water leakage holes 14 are both two. The water inlet ends of the two water guide grooves 21 are respectively connected to the two corresponding water leakage holes 14, so that the water on the curved surface of the water receiving tray 10 can flow from the two water leakage holes 14 to the two corresponding water guide grooves 21.

[0086] In some embodiments, the two water leakage holes 14 are arranged opposite to each other, and it can be understood that the line between the two water leakage holes 14 is consistent with the center line of the water receiving protrusion 13, and the line between the water inlet ends of the two water guide grooves 21 is also consistent with the center line of the water receiving protrusion 13, so that the water guide grooves 21 on the pipe body 20 are evenly distributed, and then the force exerted on the inner wall of the pipe body 20 when the water flows on the pipe body 20 is evenly distributed. This is conducive to reducing the risk of structural damage to the pipe body 20 caused by local stress concentration, and improving the stability and durability of the pipe body 20.

[0087] In some embodiments, the water channel 21 is composed of a plurality of spirals of the same size and connected, and each of the plurality of spirals has the same diameter, pitch and inclination angle. The structural dimensions of each spiral in the water channel 21 are the same, so that the force of water droplets acting on the pipe body 20 can be evenly distributed. This even distribution helps to reduce the risk of structural fatigue damage of the pipe body 20 caused by local stress concentration, improves the stability and safety of the pipe body 20, and is also conducive to the uniform falling of water droplets in the water channel 21 under the action of their own gravity, thereby optimizing the overall performance of the drain pipe 100.

[0088] It can be understood that the diameter of the spiral refers to the length required for the spiral axis to be wound into a circle, the pitch refers to the distance the spiral axis needs to move forward one circle, and the inclination angle refers to the degree of inclination of the spiral.

[0089] When the diameter of the spiral is determined, the larger the pitch, the larger the inclination angle of the spiral, and the faster the flow speed of water droplets in the spiral water guide groove 21; the smaller the pitch, the larger the inclination angle of the spiral, and the slower the flow speed of water droplets in the spiral water guide groove 21.

[0090] Here, by keeping the spiral structure size on the water guide groove 21 the same, the use of materials can be better optimized, and the amount of material required to make the pipe body 20 can be accurately calculated, thereby avoiding waste and improving material utilization. The equally spaced spiral structure design is conducive to the production and manufacturing of the drainage pipe 100, and standardized production processes and molds can be used to improve production efficiency and reduce costs.

[0091] In other embodiments, the diameter and pitch of the spiral may be adjusted according to actual needs to meet different needs. For example, the pitch of the spiral in the upper section of the pipe body 20 is set to be larger, and the pitch of the spiral in the lower section is set to be smaller, so that after the water droplets enter the water guide groove 21 from the leak hole 14, they flow through the upper section of the pipe body 20 faster, and then the flow speed slows down in the lower section. Finally, the water droplets flow quickly through the pipe body 20 and flow out of the water outlet of the water guide groove 21 at a slower flow speed, thereby improving the drainage efficiency of the drain pipe 100 and reducing the sound of water droplets dripping from the pipe body 20 to the water tank 200.

[0092] In some embodiments, the plurality of water guide grooves 21 are evenly distributed along the circumference of the tube body 20 and have the same spiral direction. Specifically, the plurality of water guide grooves 21 on the inner wall of the tube body 20 are spiral-shaped, and the plurality of spirals have the same structural size, the same spiral direction, and are staggered.

[0093] In this way, the water on the water receiving tray 10 can be effectively diverted, and the water drops flow from the multiple water leakage holes 14 of the water receiving tray 10 to the water inlet ends of the corresponding water guide grooves 21, and then flow downward from the multiple water guide grooves 21 into the water tank 200. Compared with only one water guide groove 21, the drainage capacity of the drain pipe 100 can be increased exponentially, and the load of the single water guide groove 21 can be reduced. This is conducive to reducing the risk of blockage of the pipe body 20 and improving the drainage efficiency of the drain pipe 100.

[0094] The multiple water guide grooves 21 uniformly distributed along the circumference of the tube body 20 can also effectively utilize the inner wall area of ​​the tube body 20, so that water droplets are effectively dispersed and buffered on the inner wall of the tube body 20. The water droplets flow from the water inlet end of the water guide groove 21 to the water outlet end of the water guide groove 21, and are dispersed into small water droplets on the water guide groove 21 with reduced kinetic energy, thereby reducing the sound made when the water droplets drip from the water outlet end of the water guide groove 21 to the bottom of the water tank 200.

[0095] In some embodiments, see Figure 5 , the number of water guide grooves 21 is set to two, the two water guide grooves 21 are arranged alternately, and the pitch of a single spiral on one of the water guide grooves 21 is a distance B. Figure 5 It is a cross-sectional view, which actually hides a section of the spiral line of the water guide groove 21 extending from the starting point of the distance B to the upper left vertex of the spiral line corresponding to the end point of the distance B.

[0096] In some embodiments, the water guide groove 21 is set to a rough surface. Specifically, after water drops drip from the water leakage of the water receiving tray 10 to the water inlet end of the water guide groove 21, they flow downward on the rough surface of the water guide groove 21, and finally fall into the water tank 200 from the water outlet end of the water guide groove 21. The water drops dispersed by the water receiving protrusions 13 are further dispersed in the rough surface of the water guide groove 21 to form small water drops, which can reduce the sound of water drops dripping from the water outlet end of the water guide groove 21 to the water tank 200.

[0097] When a water droplet falls on the surface of an object, it will be affected by the resistance from the surface of the object. This resistance mainly comes from the interaction between the water droplet and the surface of the object, including factors such as contact area, surface roughness, surface tension and kinetic energy of the water droplet.

[0098] First, the contact area is an important factor affecting the drag. When a water droplet contacts the surface of an object, the larger the contact area, the greater the drag the water droplet encounters. This is because a larger contact area means a stronger interaction force between the water droplet and the surface, which increases the drag.

[0099] In some embodiments, the water guide groove 21 is groove-shaped and spirally arranged on the inner wall of the tube body 20, which can effectively increase the surface area of ​​the water guide groove 21, increase the contact area between the water droplets and the water guide groove 21, and then increase the resistance between the water droplets and the water guide groove 21, so that the flow speed of the water droplets in the tube body 20 is reduced, thereby effectively reducing the sound of the water droplets falling.

[0100] Secondly, the roughness of the surface of the object will also affect the drag. A rough surface will provide more tiny bumps and depressions, which will create more contact points with the water droplets, thereby increasing the drag. In contrast, a smooth surface will reduce such contact points and reduce the drag.

[0101] In some embodiments, the water guide groove 21 is a rough surface. The increased roughness of the water guide groove 21 can increase the contact area between the water droplets and the water guide groove 21, thereby increasing the resistance to the flow of the water droplets, thereby reducing the sound of the water droplets flowing and dripping.

[0102] In addition, surface tension is also an important factor affecting the resistance of water droplets. The surface tension of water droplets is the result of the interaction between molecules on the surface of water droplets, which makes the surface of water droplets appear taut. When water droplets fall on the surface of an object, surface tension will hinder the spreading and penetration of water droplets.

[0103] In some embodiments, the water guide groove 21 is arranged in a spiral shape, and water drops with a relatively stable shape fall along the spiral trajectory of the water guide groove 21. The spiral trajectory lengthens the flow path of the water droplets in the tube body 20, increases the resistance encountered by the water droplets in the water guide groove 21, and thus reduces the sound of the water droplets falling.

[0104] The kinetic energy of a water drop also affects drag. The kinetic energy of a water drop is the energy it has when it is moving, which determines the speed and force with which the drop hits the surface. When a water drop falls at a higher speed, its kinetic energy is greater, and the drag it creates when interacting with the surface will also increase accordingly.

[0105] The rough surface has a significant effect on the flow of water droplets. The rough surface of the water guide groove 21 will have a significant effect on the flow speed and stability of the water droplets. The rough surface of the water guide groove 21 has irregular and tiny concave and convex structures, and the water droplets will encounter more obstacles and friction when flowing through these areas. In this way, the flow speed of the water droplets gradually slows down when flowing in the water guide groove 21, which can reduce the kinetic energy of the water droplets when they fall from the water outlet end of the water guide groove 21 into the water tank 200, thereby reducing the sound of the water droplets dripping from the water guide groove 21 to the water tank 200.

[0106] In some embodiments, the water receiving tray 10 and the pipe body 20 are integrally formed. Specifically, the pipe body 20 is connected below the bottom wall 11 of the water receiving tray 10, the bottom of the peripheral wall 12 of the water receiving tray 10 is connected to the pipe body 20, and the water leakage hole 14 is connected to the water guide groove 21 on the pipe body 20. The water receiving tray 10 and the pipe body 20 are integrally formed, so that the water receiving tray 10 and the pipe body 20 will not be relatively displaced to cause the water leakage hole 14 and the water guide groove 21 to be misaligned, which is conducive to ensuring the continuity of drainage of the drain pipe 100. The integrated design is also conducive to the installation and maintenance of the drain pipe 100, which can save the cost of installation and maintenance.

[0107] In other embodiments, the water receiving tray 10 and the tube body 20 may also be connected by a snap connection. Specifically, the bottom of the peripheral wall 12 of the water receiving tray 10 is snap-connected with the top of the tube body 20 , and the water leakage hole 14 is connected with the water guide groove 21 on the tube body 20 .

[0108] Figure 7 It is a structural block diagram of an air conditioning device 1000 according to an embodiment of the present utility model.

[0109] like Figure 7 As shown, the embodiment of the utility model further provides an air conditioning device 1000 .

[0110] The air conditioning device 1000 may be an air conditioner, a dehumidifier, or other equipment that can generate condensed water during operation.

[0111] The air conditioning device 1000 includes the above-mentioned drain pipe 100. The drain pipe 100 will not be described in detail here.

[0112] In this embodiment, the drain pipe 100 includes a water receiving tray 10 and a pipe body 20. The bottom wall 11 of the water receiving tray 10 is formed with a water receiving protrusion 13 protruding upward, and the water receiving tray 10 is provided with at least one water leakage hole 14. The pipe body 20 is connected to the bottom of the water receiving tray 10 to allow water drops flowing down from the top of the water receiving tray 10 to fall on the water receiving protrusion 13, flow downward along its surface, and enter the pipe body 20 through the water leakage hole 14 to reduce the water flow noise. The setting of the water receiving protrusion 13 can effectively buffer the water and prevent the water from directly "smashing" the bottom of the water receiving tray 10 to generate a large noise. Moreover, the water receiving protrusion 13 can also effectively reduce the falling distance of water from the air conditioning equipment 1000 to the water receiving tray 10 after dripping. The water is dispersed into small water droplets at the water receiving protrusion 13 and further dispersed in the pipe body 20, further reducing the sound of water droplets flowing and improving the user experience.

[0113] In addition, in some embodiments, the water guide groove 21 of the tube body 20 is set to a spiral shape, which can make full use of the inner wall area of ​​the tube body 20, lengthen the flow path of water droplets in the tube body 20, further disperse the water, reduce the sound of water flowing in the tube body 20, and reduce the kinetic energy of water droplets flowing out from the water outlet end of the water guide groove 21, so that the water droplets fall gently to the bottom of the water tank 200, reducing the sound of water droplets falling to the water tank 200.

[0114] In some embodiments, the air conditioning device 1000 is a dehumidifier, and the dehumidifier generates condensed water after the condensation operation is performed, and the condensed water is discharged from the drain port of the dehumidifier. The drain pipe 100 is installed on the water tank 200 and is located below the drain port. The water receiving tray 10 of the drain pipe 100 is used to carry the water discharged from the drain port, and the pipe body 20 is used to drain the water flowing down from the water leakage hole 14 of the water receiving tray 10 to the bottom of the water tank 200.
