Description

Technical Field

[0001] This utility model relates to a water-receiving structure and an air conditioner having the same, specifically, to a water-receiving structure and an air conditioner having the same. Background Technology

[0002] Currently, condensate management is a crucial aspect of equipment design in the air conditioning industry. The condensate tray and drain nozzle, as core components of condensate management, directly impact equipment performance and user experience through their design.

[0003] However, existing drain nozzle designs often fail to adequately consider water flow control during discharge. Most drain nozzles have a simplistic internal structure, such as only using ribs, which cannot effectively control water flow velocity. Especially when condensate flow is high, the ribs cannot completely separate the water flow, resulting in excessively fast flow that directly impacts the drain pipe or the bottom of the drip tray, generating significant noise and hindering smooth water flow. Furthermore, imprecise control of water inlet and outlet leads to an unpredictable flow trajectory within the drain nozzle, affecting flow stability and increasing noise levels. Utility Model Content

[0004] The main purpose of this utility model is to provide a water receiving structure and an air conditioner having it, so as to solve the technical problems of high noise and insufficient drainage in the existing water receiving pan.

[0005] To achieve the above objectives, according to one aspect of the present invention, a water-receiving structure is provided, comprising:

[0006] A water receiving tray, wherein the water receiving tray has a water collection trough and a drain outlet that are interconnected;

[0007] A drain nozzle is disposed at the bottom of the water receiving tray. The drain nozzle includes a guide section and an outlet section connected together. The guide section is disposed above the outlet section and has a guide groove. The guide groove extends downward in a spiral manner. The guide inlet of the guide groove is connected to the drain outlet, and the guide outlet of the guide groove is connected to the outlet section.

[0008] Furthermore, along the extension direction from the guide section to the outlet section, the flow cross-sectional area of ​​the guide section gradually decreases; and / or,

[0009] The guide section has a guide cavity that extends along the direction from the guide section to the outlet section, and the guide groove is provided on the inner sidewall of the guide cavity.

[0010] Furthermore, there are multiple guide channels, and the multiple guide channels are arranged at intervals;

[0011] Wherein, the flow inlets of the plurality of flow guide channels are spaced apart along the circumferential direction; and / or,

[0012] The flow inlets of the multiple flow guide channels are evenly distributed along a preset direction.

[0013] Furthermore, the drain nozzle also includes:

[0014] A flow-guiding structure is provided at the flow-guiding inlet of the flow-guiding channel. The flow-guiding structure protrudes from the channel wall of the flow-guiding channel and is located at the edge of the flow-guiding channel.

[0015] Furthermore, the drainage structure includes:

[0016] A flow guide plate is disposed at the flow inlet of the flow guide groove, and the flow guide plate extends along the spiral extension direction of the flow guide groove.

[0017] Furthermore, the flow guiding section includes a first flow guiding shell and a second flow guiding shell connected to each other. The first flow guiding shell is disposed on the side of the second flow guiding shell away from the outlet section. Both the first flow guiding shell and the second flow guiding shell are conical shells, and the taper of the first flow guiding shell is greater than the taper of the second flow guiding shell.

[0018] The diversion plate protrudes from the end of the first diversion shell that is away from the second diversion shell.

[0019] Furthermore, the angle between the bottom of the guide channel and the horizontal direction is α, where 15°≤α≤25°.

[0020] Furthermore, the drain nozzle also includes:

[0021] A buffer section is disposed between the guide section and the outlet section, the buffer section having a buffer cavity communicating with both the guide outlet and the outlet section; along the extension direction from the guide section to the outlet section, at least a portion of the flow cross-sectional area of ​​the buffer cavity is greater than or equal to the flow cross-sectional area at the connection between the guide section and the buffer section.

[0022] Furthermore, the flow cross-section of the buffer cavity is circular, and the diameter of the flow cross-section of the buffer cavity is less than or equal to 50 mm and greater than or equal to 35 mm; and / or;

[0023] Along the extension direction from the guide section to the outlet section, the flow cross-sectional area of ​​the buffer section first gradually increases and then gradually decreases.

[0024] According to another aspect of the present invention, an air conditioner is provided, including the water receiving structure provided above.

[0025] By applying the technical solution of this utility model, the water receiving structure of this application effectively extends the water flow path and reduces the direct impact of water flow on the bottom of the drain nozzle by setting a spiral guide channel in the guide section of the drain nozzle, thereby significantly reducing noise during the drainage process. Simultaneously, by optimizing the angle and number of guide channels, the smooth and uniform water flow is ensured, avoiding drainage problems caused by excessively fast or slow water flow. Furthermore, the design of the buffer section further reduces the water flow velocity, ensuring a smooth water flow at the outlet section, improving the stability and reliability of the entire drainage system. These improvements not only enhance the user experience of the air conditioning equipment but also extend its service life. Moreover, with the water receiving structure of this application, users can hardly perceive the noise generated by drainage during the operation of the air conditioning equipment, creating a quieter operating environment. At the same time, because the water flow velocity is effectively controlled, the risk of condensate backflow or overflow is avoided, protecting the internal structure of the equipment and reducing maintenance costs. In addition, the structure is simple in design and easy to manufacture and install. Attached Figure Description

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] like Figures 1 to 7As shown, Embodiment 1 of this utility model provides a water receiving structure, including: a water receiving tray 10 and a drain nozzle 20. The water receiving tray 10 has a water collection trough and a drain outlet that are interconnected. The drain nozzle 20 is disposed at the bottom of the water receiving tray 10. The drain nozzle 20 includes a guide section 21 and an outlet section 22 that are connected together. The guide section 21 is disposed above the outlet section 22. The guide section 21 has a guide groove 211. The guide groove 211 extends downward in a spiral manner. The guide inlet 2111 of the guide groove 211 is connected to the drain outlet, and the guide outlet of the guide groove 211 is connected to the outlet section 22.

[0053] This embodiment extends the water flow path and reduces the direct impact of water flow on the bottom of the drain nozzle 20 by designing a spiral guide groove 211 inside the guide section 21 of the drain nozzle 20. Simultaneously, the spiral structure helps guide the water flow into the central buffer cavity, ensuring smooth drainage of condensate. In principle, the spiral guide groove 211 utilizes the synergistic effect of centrifugal force and gravity to optimize water flow velocity and promote energy dissipation, thereby reducing noise and impact. In terms of effect, the spiral guide groove 211 in this embodiment can slow down the water flow, reduce flow velocity, decrease noise, and prevent water flow from affecting drainage efficiency due to impact or blockage. In other embodiments, the spiral angle, width, or depth of the spiral groove can be changed to further optimize water flow velocity and noise control, solving technical problems such as uneven water flow velocity, excessive noise, or poor drainage.

[0054] Specifically, along the extension direction from the guide section 21 to the outlet section 22, the flow cross-sectional area of ​​the guide section 21 gradually decreases; and / or, the guide section 21 has a guide cavity that extends along the direction from the guide section 21 to the outlet section 22, and the guide groove 211 is provided on the inner sidewall of the guide cavity; and / or, there are multiple guide grooves 211, and the multiple guide grooves 211 are spaced apart.

[0055] This embodiment adjusts the flow cross-section of the guide section 21 to gradually slow the water flow as it passes through, further reducing noise. It also ensures that the water maintains a certain outflow velocity after passing through the longer guide channel 211, guaranteeing concentrated outflow. The design of multiple guide channels 211 ensures uniform water distribution, avoiding problems of excessively fast or slow flow in certain areas. In principle, the gradual reduction of the flow cross-section utilizes fluid dynamics principles, combined with the magnitude of centrifugal force, to ensure smooth discharge at a predetermined speed after deceleration through the guide channel 211. The spacing of the multiple guide channels 211 utilizes fluid distribution principles to ensure uniform water flow within the guide section 21. In terms of effectiveness, the technology in this embodiment further reduces water flow velocity and noise, while ensuring uniform water flow distribution and preventing drainage problems caused by excessively fast or slow flow in certain areas. In other embodiments, the water flow distribution and noise reduction can be optimized by changing the spacing between the guide channels 211 or the flow cross-sectional shape of the guide section 21, thereby solving the technical problems of uneven water flow distribution or poor noise control.

[0056] Specifically, the guide section 21 is a guide shell, and the flow cross section of the guide section 21 is the flow cross section enclosed by the guide shell. Specifically, the guide section 21 is a conical shell, and the guide cavity enclosed by the guide section 21 is a conical cavity. The flow cross section of the guide section 21 can be understood as the flow cross section of the conical cavity.

[0057] Specifically, there are multiple flow guide channels 211; wherein the flow guide inlets 2111 of the multiple flow guide channels 211 are spaced apart along the circumferential direction; and / or, the flow guide inlets 2111 of the multiple flow guide channels 211 are evenly distributed along a preset direction.

[0058] This embodiment ensures uniform water flow upon entering the guide section 21 by evenly distributing multiple guide channels 211, avoiding localized impact and noise problems caused by water concentrating in a certain area. The circumferential spacing or even distribution of the multiple guide channels 211 utilizes fluid distribution principles to ensure uniform water flow within the guide section 21. In terms of effectiveness, the technology in this embodiment ensures uniform water flow distribution, avoids noise and impact caused by excessively fast localized water flow, and improves drainage efficiency. In other embodiments, the number or distribution of the guide channels 211 can be changed to further optimize water flow distribution and reduce noise, solving technical problems of uneven water flow distribution or poor noise control.

[0059] Preferably, there are three guide channels 211, and the central angle between two adjacent guide channels 211 is 120°.

[0060] In this embodiment, there are multiple guide channels 211; the drain nozzle 20 also includes a flow guiding structure 23, which is disposed at the flow inlet 2111 of the guide channel 211. The flow guiding structure 23 protrudes from the wall of the guide channel 211 and is located at the edge of the guide channel 211. This structural arrangement facilitates the shielding of the corresponding flow inlet 2111 at the edge of the guide channel 211, thereby ensuring stable guidance of the water flow at the flow inlet 2111 and further guiding the water flow along a predetermined trajectory, preventing mutual interference between the guide channels 211. In principle, the design of the flow guiding structure 23 utilizes the principle of fluid guidance to ensure stable water flow in the guide channel 211, preventing deviation or overflow. In terms of effectiveness, the technology in this embodiment ensures that each guide channel 211 has an independent water flow path, avoiding mutual interference between water flows and improving drainage efficiency and stability. In other embodiments, the water flow path can be further optimized by changing the shape or position of the drainage structure 23, thereby solving the technical problems of unstable water flow path or low drainage efficiency.

[0061] In this embodiment, the flow guiding structure 23 includes a flow guiding plate 231, which is disposed at the flow guiding inlet 2111 of the flow guiding groove 211. The flow guiding plate 231 extends along the spiral extension direction at the flow guiding inlet 2111 of the flow guiding groove 211.

[0062] Specifically, the diversion plate 231 facilitates the isolation and diversion of water flow at the inlet 2111 of the guide channel 211, preventing water from overflowing from the edge of the guide channel 211. The diversion plate 231 further refines the water flow guidance, ensuring stable flow as the water enters the guide channel 211. In principle, the design of the diversion plate 231 utilizes fluid guidance principles to ensure stable water flow within the guide channel 211, preventing deviation or overflow. In terms of effectiveness, the technology in this embodiment ensures stable water flow within the guide channel 211, preventing deviation or overflow, and improving drainage efficiency and stability. In other embodiments, the shape or position of the diversion plate 231 can be changed to further optimize the water flow path and solve technical problems of unstable water flow or low drainage efficiency.

[0063] Specifically, the flow guiding section 21 includes a first flow guiding shell 212 and a second flow guiding shell 213 connected to each other. The first flow guiding shell 212 is disposed on the side of the second flow guiding shell 213 away from the outlet section 22. Both the first flow guiding shell 212 and the second flow guiding shell 213 are conical shells, and the taper of the first flow guiding shell 212 is greater than the taper of the second flow guiding shell 213. At least a portion of the flow guiding plate 231 extends out of the end of the first flow guiding shell 212 away from the second flow guiding shell 213.

[0064] This embodiment further optimizes the guidance and distribution of water flow by setting a first guide shell 212 and a second guide shell 213, and a guide plate 231 between the guide inlet 2111, ensuring stable water flow when entering the guide channel 211. In principle, the design of the first guide shell 212 and the second guide shell 213 utilizes the principle of fluid distribution to ensure uniform water flow when entering the guide channel 211; the design of the guide plate 231 utilizes the principle of fluid guidance to ensure stable water flow when entering the guide channel 211. In terms of effect, the technology in this embodiment ensures stable water flow when entering the guide channel 211, preventing water deviation or overflow, and improving drainage efficiency and stability. In other embodiments, the water flow path and distribution can be further optimized by changing the taper of the first guide shell 212 and the second guide shell 213 or the extension length of the guide plate 231, solving the technical problems of unstable water flow path or low drainage efficiency.

[0065] Specifically, the angle between the bottom of the guide channel 211 and the horizontal direction is α, where 15°≤α≤25°.

[0066] This embodiment ensures stable water flow within the guide channel 211 by setting the angle α between the bottom of the channel and the horizontal direction to between 15° and 25°, thus avoiding noise or blockage problems caused by excessively fast or slow water flow. In principle, the angle α design utilizes fluid dynamics principles, optimizing water flow velocity and promoting energy dissipation by balancing the synergistic effect of centrifugal force and gravity, thereby reducing noise and impact. In terms of effectiveness, the technology in this embodiment ensures stable water flow within the guide channel 211, avoiding noise or blockage problems caused by excessively fast or slow water flow, and improving drainage efficiency and stability. In other embodiments, the range of angle α can be changed to further optimize water flow velocity and noise control, solving technical problems of uneven water flow velocity or excessive noise.

[0067] In this embodiment, the drain nozzle 20 further includes a buffer section 24, which is disposed between the guide section 21 and the outlet section 22. The buffer section 24 has a buffer cavity 241 that communicates with both the guide outlet and the outlet section 22. Along the extension direction from the guide section 21 to the outlet section 22, at least a portion of the flow cross-sectional area of ​​the buffer cavity 241 is greater than or equal to the flow cross-sectional area at the connection between the guide section 21 and the buffer section 24.

[0068] Specifically, at least a portion of the flow cross-sectional area of ​​the buffer cavity 241 is greater than or equal to the flow cross-sectional area at the connection between the guide section 21 and the buffer section 24, which facilitates providing a sufficiently large buffer cavity 241 to buffer the water flow, reduce the speed of the water flow, and also facilitates reducing the noise generated by the water flow.

[0069] This embodiment further reduces the water flow velocity by incorporating a buffer section 24 in the drain nozzle 20, ensuring a smooth transition of the water flow as it exits the guide section 21. In principle, the design of the buffer section 24 utilizes the fluid buffering principle, reducing the flow velocity by increasing water flow resistance, thus ensuring a smooth transition of the water flow as it exits the guide section 21. In terms of effectiveness, the technology in this embodiment can further reduce the water flow velocity, ensuring a smooth transition of the water flow as it exits the guide section 21, and avoiding noise or poor drainage problems caused by water flow impact or blockage. In other embodiments, the flow cross-sectional area or shape of the buffer section 24 can be changed to further optimize the water flow velocity and smooth transition, solving technical problems of poor smooth water flow transition or poor noise control.

[0070] Specifically, the flow cross-section of the buffer cavity 241 is circular, and the diameter of the flow cross-section of the buffer cavity 241 is less than or equal to 50 mm and greater than or equal to 35 mm; and / or, along the extension direction from the guide section 21 to the outlet section 22, the flow cross-sectional area of ​​the buffer section 24 gradually increases and then gradually decreases.

[0071] This embodiment ensures stable water flow in the buffer section 24 by setting the flow cross-section of the buffer cavity 241 to be circular, with a diameter between 35mm and 50mm, thus avoiding noise or blockage problems caused by excessively fast or slow water flow. In principle, the flow cross-section design of the buffer cavity 241 utilizes fluid dynamics principles. By optimizing the shape and size of the flow cross-section, stable water flow in the buffer section 24 is ensured, avoiding noise or blockage problems caused by excessively fast or slow water flow. In terms of effectiveness, the technology in this embodiment ensures stable water flow in the buffer section 24, avoiding noise or blockage problems caused by excessively fast or slow water flow, thereby improving drainage efficiency and stability. In other embodiments, the shape or size of the flow cross-section of the buffer cavity 241 can be changed to further optimize water flow velocity and noise control, solving technical problems of uneven water flow velocity or excessive noise.

[0072] like Figure 1 , 2 As shown, the water receiving structure of this application is mainly located at the bottom of the water receiving tray. A guide wall structure (corresponding to a guide plate 231) is added inside the drain nozzle, allowing the condensate generated during evaporator operation to enter the drain nozzle through the guide wall. Simultaneously, a spiral guide groove 211 is designed in the upper half of the drain nozzle, allowing the water to flow down the spiral guide groove 211 after entering the guide wall. A buffer cavity 241 (which can be a spherical cavity) is designed in the middle of the lower half of the drain nozzle, allowing the water to flow towards the inner wall of the cavity and then slowly flow down. To ensure the water flows towards the cavity wall, a water outlet wall is designed at the end of the spiral guide groove 211, allowing the water to flow towards the buffer cavity in a fixed direction and then slowly flow out. This design achieves the effect of allowing the condensate generated by the evaporator to flow slowly out of the water receiving tray, thereby avoiding noise caused by excessive water flow velocity.

[0073] like Figure 3 As shown, the structure of the drain nozzle described in this application includes three guide channels inside its upper section. The central angle between each guide channel 211 is 120°. These three guide channels 211 extend downwards in a spiral pattern until they intersect with the central buffer cavity. The angle range of these three guide channels 211 is between 15° and 25° with respect to the horizontal direction. This is designed to optimize the water flow velocity and promote energy dissipation by balancing the synergistic effect of centrifugal force and gravity, thereby reducing noise and impact. This angle range ensures that the water flows stably along the channel wall, preventing deviation or overflow due to inertial force. It also takes into account the feasibility of the manufacturing process and the structural stability, achieving efficient and stable drainage and reducing the risk of clogging.

[0074] At the inlet, three guide channels are each designed with a baffle wall (corresponding to a flow guide plate), which extends only a certain distance along the guide channel's trajectory. This baffle wall design allows water flow from all directions to be introduced into and flow along the guide channels, while preventing water from flowing from one guide channel to another, ensuring that each guide channel has an independent flow path. This not only helps to evenly distribute the water flow but also prevents water flow from interfering with each other between the guide channels.

[0075] like Figure 4 , 5 As shown, this is a schematic diagram of the water inflow from the receiving pan to the drain nozzle. When condensate is generated and flows into the receiving pan 10, it flows from all directions to the inlet of the drain nozzle 20. The guide wall at the inlet divides the water into three directions, which flow into the spiral guide channel 211 inside the drain nozzle. Under the action of inertia, gravity, and centrifugal force, the water flows down along the trajectory of the guide channel 211 in a rotating manner. When it reaches the end of the guide channel 211, due to the water flow speed and inertia, it falls in a parabolic shape and finally hits the buffer wall of the inner wall of the circular cavity. When the water hits the wall, the inner cavity will exert a reaction force on the water, which will rapidly reduce the water flow speed, thereby achieving the function of buffering the water flow and reducing the flow rate. The optimal range of the diameter of the circular inner cavity is usually between 35mm and 50mm. If the diameter is too small, it may cause the water flow speed to be too fast, increase the impact noise, or increase the risk of blockage. If it is too large, it may reduce the flow rate and increase the space occupation. At the same time, it is necessary to ensure that the structural strength matches the overall size of the equipment. Finally, the water will slowly flow down the inner cavity and out of the drain nozzle.

[0076] Specifically, the condensate flowing down can be categorized into four states:

[0077] Phase 1: (Water tray 10 → Inlet of drain nozzle 20 (i.e., the opening at the top of drain nozzle 20)):

[0078] The condensate produced by the evaporator flows through the evaporator wall to the water receiving pan 10. The water is subject to gravity and generates a flow velocity. After reaching the inlet of the drain nozzle 20, it is separated by the partition wall and flows into the guide channel 211.

[0079] Second stage: (Inlet of drain nozzle → Inlet 2111 of guide channel 211):

[0080] After entering the inlet of the drain nozzle, the water flows into the spiral guide channel 211. Within the spiral channel, the water flow is subjected to the combined effects of centrifugal force, gravity, inertial force, viscous force, pressure gradient force, and vortex effect, forming a stable spiral trajectory. Centrifugal force deflects the water flow outwards, gravity drives the water flow axially downwards, inertial force maintains the rotational tendency of the water flow, viscous force consumes kinetic energy and slows the flow velocity, and pressure gradient force propels the water flow along the spiral path. Simultaneously, the vortex effect enhances water mixing and further dissipates energy. This complex motion causes the water to flow both axially downwards and outwards due to centrifugal force, resulting in a uniform pressure distribution and energy dissipation. This effectively reduces flow velocity, disperses pressure, reduces noise, and prevents the water flow from being affected by impact or blockage, thus improving drainage efficiency.

[0081] Third stage: (Outlet of guide channel 211 → Cavity wall):

[0082] After leaving the guide channel 211, the water flows in a parabolic motion due to inertia (horizontal velocity) and free fall (vertical acceleration), colliding with the inner wall of the circular cavity. The velocity at the moment of impact with the inner wall of the circular cavity is determined by both the horizontal and vertical components: the horizontal velocity is usually not zero, and the water continues to move in the horizontal direction; the vertical velocity gradually decreases at the moment of impact due to the wall reaction force and energy dissipation (such as viscous friction and vortex), and the water will slide or disperse along the wall.

[0083] Fourth stage: (Cavity wall → Drain outlet):

[0084] After the water flow hits the inner wall of the circular cavity, its speed decreases, and it slides down the wall to the drain outlet. Ultimately, this reduces the water flow velocity.

[0085] To determine the water flow inside the drain nozzle and verify the influence of the internal structure of the drain nozzle described in this proposal on the water flow velocity, simulation analysis of the condensate flow at the evaporator drain nozzle was performed using simulation software. Figure 8 As shown, a simulation model of the condensate tray is established, with the water inlet set as a velocity flow inlet and the outlet at the drain nozzle set as a natural flow outlet, ensuring a complete simulation of the condensate flowing out of the condensate tray. (See attached image) Figure 9The image shows a cloud map simulating the water flow velocity and flow conditions inside the drain nozzle. The long colored strips on the left side of the image represent the water flow velocity corresponding to different colors. Therefore, by observing the water flow color inside the drain nozzle on the right, we can see that the water flow is darker in the spiral guide channel 211, and the water flow velocity reaches its maximum at the end of the guide channel 211. This is consistent with the reason why the water speed increases as it falls down the guide channel 211 due to gravity. Subsequently, the water flows towards the inner wall of the circular inner cavity. As shown in the simulation results, the water flow color is relatively lighter after reaching the inner wall, indicating that the water flow velocity is lower. This is consistent with the reason why the water flow velocity decreases after hitting the buffer inner wall. Afterward, the water flows slowly down the inner wall.

[0086] Through the Figure 8 Simulated velocity contour plot analysis shows that the water flow velocity inside the drain nozzle gradually increases after entering the spiral guide channel 211, reaching its maximum at the end of the guide channel 211. Then, due to the velocity, it flows in a parabolic shape towards the inner buffer wall, where the velocity decreases. The inner buffer wall effectively reduces the water flow velocity, and the water then flows down slowly. Therefore, the internal structure of the drain nozzle described in this proposal can effectively reduce the water flow velocity.

[0087] To verify whether the noise generated during the process of condensate flowing from the drip tray 10 into the drain nozzle 20 and then out to the lower drip collection device would significantly impact the user experience, Ansys software was used to simulate the noise level of the condensate flow. A simulation model was established, and a 150mm high drip collection device was designed at the lower outlet of the drain nozzle 20 to simulate the phenomenon of condensate flowing from the drain nozzle to the bottom drip tray in a cabinet air conditioner. Figure 9 The diagram shows the noise level cloud map on the surface of the water receiving tray 10. The long colored bar on the left side of the diagram represents the noise level; the darker the color, the greater the noise intensity. The right side of the diagram shows the noise from the inner wall of the drain nozzle 20 and the bottom surface of the water receiving device. By examining the diagram, it can be seen that the noise mainly originates from water hitting the wall. Therefore, there is basically no sound in the center of the diagram, while the wall surface contains some noise. Based on the analysis of the decibel values ​​corresponding to the colors on the wall, the walls of the drain nozzle 20 and the bottom water receiving device are relatively light in color, indicating that the sound level generated by the condensate flowing into the drain nozzle 20 and the bottom wall is relatively low.

[0088] Through the Figure 9 The sound simulation cloud map analysis shown shows that the sound decibel value of the water flow inside the drain nozzle 20 is low, and the noise generated when the water flows to the bottom of the water receiving device is also low. Therefore, the internal structure of the drain nozzle 20 described in this proposal can reduce the water flow rate and thus reduce the generation of noise.

[0089] In order to understand the water flow state of the guide channel 211 at different angles and obtain the optimal angle of the guide channel 211, guide channel structures with different inclination angles α were designed inside the drain nozzle 20. The water flow conditions at different angles were verified by simulating the water flow velocity at two different drain nozzles 20.

[0090] like Figure 10 The figure above shows the water flow at the drain nozzle 20 when the angle α of the guide channel 211 is 40°. By examining the velocity contour map inside the channel, it can be seen that due to the large angle of the guide channel 211, the water flow has a strong impact force, and the maximum water flow inside the guide channel 211 can reach 5.51 m / s. As shown on the right side of the figure above, the water flow at the drain nozzle 20 when the angle of the guide channel 211 is 10° shows the maximum water flow inside the guide channel 211, which is 2.13 m / s, indicating a slower flow.

[0091] like Figure 11 As shown in the diagram, the velocity profile of the water flow inside the guide channel is analyzed. When the angle α of the guide channel 211 is large, the water flow velocity inside the drain nozzle 20 is relatively fast, which may cause noise during outflow. When the angle α of the guide channel 211 is small, the water flow velocity inside the drain nozzle 20 is relatively slow and low. However, as can be seen from the velocity profile, if the water flow velocity is low, water flow congestion may occur inside the guide channel 211 and the circular cavity, resulting in water overflowing from the water receiving tray 10 due to the inability of the water flow to exit.

[0092] Therefore, through simulation results analysis, the water flow inside the drain nozzle 20 increases with the increase of the angle α of the guide channel 211. However, if the water flow velocity is too high inside the drain nozzle 20, it will generate noise, and if the water flow velocity is too low, it will cause water accumulation. Therefore, the water flow velocity is suitable when the angle α of the guide channel 211 inside the drain nozzle 20 is 15-25°.

[0093] According to another embodiment of this utility model, an air conditioner is provided, including the aforementioned water-receiving structure. This embodiment, by applying the water-receiving structure described above to the air conditioner, ensures the smooth drainage of condensate during operation, avoiding noise or equipment damage caused by condensate accumulation. In principle, the design of the water-receiving structure utilizes fluid dynamics and fluid distribution principles, optimizing the water flow path and velocity to ensure smooth condensate drainage. In terms of effectiveness, the technology in this embodiment ensures smooth condensate drainage during air conditioner operation, avoiding noise or equipment damage caused by condensate accumulation, thus improving the operating efficiency of the air conditioner and the user experience. In other embodiments, the water-receiving structure can be applied to different types of air conditioners to further optimize condensate drainage efficiency and noise control, solving the technical problems of low condensate drainage efficiency or excessive noise.

[0094] The air conditioner in this embodiment can be a floor-standing air conditioner.

[0095] When the air conditioner is running, the condensate produced on the evaporator surface flows into the collection tray 10. The condensate then enters the guide section 21 of the drain nozzle 20 through the drain outlet, flowing downwards along the spiral guide channel 211. During this flow, the water is guided by the guide plate 231, ensuring a stable and uniform distribution. As the water flows through the guide channel 211, the angle α between the bottom of the guide channel 211 and the vertical direction is optimized, preventing noise or blockage caused by excessively fast or slow flow. After leaving the guide channel 211, the water enters the buffer section 24, where the flow velocity is further reduced by the buffer chamber 241, ensuring a smooth transition when leaving the buffer section 24. Finally, the water flows smoothly out of the air conditioner through the outlet section 22, avoiding noise or poor drainage caused by water impact or blockage. The entire process ensures smooth drainage of condensate during air conditioner operation, improving operating efficiency and user experience.

[0096] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By designing a spiral guide groove on the inner wall of the drain nozzle, the water flow path can be extended, reducing the direct impact of water flow on the bottom of the drain nozzle. At the same time, the spiral structure also helps to guide the water flow into the central buffer cavity, ensuring that condensate can be discharged smoothly. By designing inlet and outlet walls (corresponding to guide plates 231) at the beginning and end of the spiral guide groove 211, water flow can be prevented from flowing from one guide groove to another, ensuring that each guide groove has an independent water flow path. By designing an inner cavity in the middle section of the drain nozzle, the water flow is slowed down by hitting the inner cavity when flowing down from the guide groove 211, thereby avoiding noise when flowing out of the drain nozzle.
