Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to an anti-condensation drainage device for a low static pressure duct air conditioner. Background Technology

[0002] Low static pressure duct air conditioners are widely used in air conditioning systems of various buildings such as residences, office buildings, and commercial complexes due to their advantages such as flexible installation and gentle air delivery. During the cooling operation, the surface temperature of the evaporator inside the duct air conditioner will be lower than the air dew point temperature. Water vapor in the air will condense on the evaporator surface after encountering the cold air, forming condensation. Therefore, the performance of the drainage device directly affects the operational stability of the equipment and the user experience.

[0003] Existing anti-condensation drainage devices for low static pressure duct air conditioners have many design flaws: On the one hand, the connection between the water collection hopper and the main body of the equipment is often simply fitted or fixed with a single bolt, resulting in an imperfect sealing structure design. This makes them prone to condensation leakage due to vibration and installation deviations. At the same time, the components of the drainage channel are not connected on the same axis, which increases drainage resistance and lacks an effective anti-siphon backflow structure, which can easily cause condensation backflow and affect drainage efficiency. On the other hand, the drainage pipes do not have a self-cleaning mechanism. After long-term use, impurities carried in the condensation can easily adhere to the pipe wall, causing pipe blockage. Moreover, most of the components are fixed connections, requiring professional tools for disassembly and assembly, making subsequent inspection and cleaning difficult and costly, which seriously affects the service life and operational reliability of the equipment.

[0004] To address the aforementioned problems, the inventors have proposed an anti-condensation drainage device for low static pressure duct air conditioners. Utility Model Content

[0005] In order to solve problems such as sealing leakage, drainage backflow, blockage and inconvenient maintenance, the purpose of this utility model is to provide an anti-condensation drainage device for low static pressure duct air conditioners.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a low static pressure duct air conditioner anti-condensation drainage device, comprising a main body, a water collection bucket assembly bolted to the bottom of the main body, a drainage assembly detachably connected to the bottom of the water collection bucket assembly, an evaporator fixedly installed inside the main body, and a duct fixedly provided on one side of the main body.

[0007] Preferably, the water collection hopper assembly includes a housing, which is bolted to the bottom of the main body. A sealing strip is fixedly provided on the upper surface of the housing. The sealing strip is embedded in an annular groove on the upper surface of the housing, and the upper end face of the sealing strip is in contact with the bottom of the main body. A perforated guide plate is detachably connected inside the housing. A siphon valve is fixedly provided at the bottom of the housing. A connecting flange is fixedly connected to the outer surface of the siphon valve. The inner hole of the connecting flange is coaxially arranged with the drainage channel of the siphon valve. A drainage elbow is detachably connected to the bottom of the siphon valve.

[0008] Preferably, the drainage assembly includes a straight pipe, which is detachably connected to one end of a drainage elbow. The end of the straight pipe away from the drainage elbow is detachably connected to a bend. A fixing block is fixedly connected to the top of the inner wall of the straight pipe, and a bearing is fixedly connected to the bottom of the fixing block. A rotating shaft is sleeved inside the bearing, and a scraper is fixedly connected to the outer surface of the rotating shaft. Multiple scrapers are provided and are evenly distributed along the axial direction of the rotating shaft.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a sealing strip on the upper surface of the water collection hopper shell to be embedded in an annular groove and tightly fit the bottom of the main body, blocking the condensation leakage path at the joint. The inner hole of the connecting flange is coaxially set with the siphon valve drainage channel. Combined with the precise connection of the drainage elbow and the straight pipe, it ensures smooth conduction of the drainage channel throughout, reducing flow resistance. At the same time, the siphon valve effectively blocks siphon backflow, realizing one-way and efficient discharge of condensation. It is perfectly adapted to the operating conditions of low static pressure air duct fans and avoids the impact of dripping and backflow on the equipment.

[0010] 2. In the drainage component of this utility model, the bearing, the rotating shaft and multiple axially evenly distributed scrapers form a self-cleaning structure. The flow of condensation can drive the scrapers to rotate and continuously scrape the inner wall of the straight pipe to avoid the adhesion and blockage of impurities. The water collection bucket component and the main body, the drainage component and the water collection bucket, the straight pipe and the bend pipe and the multi-hole guide plate are all detachably connected, which facilitates quick disassembly and maintenance, replacement of parts and cleaning of impurities in the later stage. No complicated tools are required, which greatly improves the convenience of maintenance and reduces the downtime of equipment maintenance. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3 As shown, this utility model provides an anti-condensation drainage device for a low static pressure duct air conditioner, including a main body 1. A water collection bucket assembly 2 is bolted to the bottom of the main body 1. The water collection bucket assembly 2 is used to collect condensation. A drainage assembly 3 is detachably connected to the bottom of the water collection bucket assembly 2. The drainage assembly 3 is responsible for draining the condensation. An evaporator 4 is fixedly installed inside the main body 1. The evaporator 4 is the core component for condensation generation. The fixed installation ensures stable operation. Condensation forms on its surface. A duct 5 is fixedly installed on one side of the main body 1.

[0018] The water collection hopper assembly 2 includes a housing 21, which is bolted to the bottom of the main body 1. A sealing strip 22 is fixedly provided on the upper surface of the housing 21. The sealing strip 22 is used to seal the connection gap between the housing 21 and the main body 1. The sealing strip 22 is embedded in an annular groove opened on the upper surface of the housing 21 to prevent the sealing strip 22 from shifting. The upper end face of the sealing strip 22 is in contact with the bottom of the main body 1. A perforated guide plate 23 is detachably connected inside the housing 21. The perforated guide plate 23 accelerates the condensation flow. The detachable connection facilitates regular cleaning and avoids the accumulation of impurities affecting the flow. A siphon valve 24 is fixedly provided at the bottom of the housing 21. The siphon valve 24 is used to block the siphon backflow phenomenon. The fixed setting ensures the structural stability during drainage and ensures unidirectional flow of condensation. A connecting flange 25 is fixedly connected to the outer surface of the siphon valve 24. The inner hole of the connecting flange 25 is coaxially set with the drainage channel of the siphon valve 24. The coaxial setting ensures smooth flow of the drainage channel and reduces the flow resistance of condensation. A drainage elbow 26 is detachably connected to the bottom of the siphon valve 24.

[0019] The drainage component 3 includes a straight pipe 31, which is detachably connected to one end of a drain elbow 26. The end of the straight pipe 31 away from the drain elbow 26 is detachably connected to a bend 35. A fixing block 32 is fixedly connected to the top of the inner wall of the straight pipe 31, providing an installation support point for the bearing 36. The fixed connection ensures that the bearing 36 is installed stably. The bearing 36 is fixedly connected to the bottom of the fixing block 32. A rotating shaft 33 is sleeved inside the bearing 36. The sleeve connection enables the rotating shaft 33 to be rotatably installed, ensuring that the rotating shaft 33 rotates smoothly. A scraper 34 is fixedly connected to the outer surface of the rotating shaft 33. The scraper 34 rotates with the rotating shaft 33 to clean the inner wall of the straight pipe 31. Multiple scrapers 34 are provided and are evenly distributed along the axial direction of the rotating shaft 33. The even distribution ensures that the cleaning covers the entire inner wall of the straight pipe 31, avoiding the adhesion of impurities that may cause pipe blockage.

[0020] Working principle: When the low static pressure duct air conditioner is running, the air duct 5 on one side of the main body 1 delivers air. When the air flows through the evaporator 4 fixedly installed inside the main body 1, water vapor condenses on the surface of the evaporator 4 to form condensate. The condensate drips into the water collection bucket assembly 2 bolted to the bottom of the main body 1 under the action of gravity. The outer shell 21 provides a stable collection space for the condensate. The porous guide plate 23 inside can accelerate the condensate flow and the detachable design facilitates subsequent cleaning of impurities and avoids obstruction of the flow channel.

[0021] The sealing strip 22 on the upper surface of the outer shell 21 is embedded in the annular groove and fits tightly against the bottom of the main body 1, effectively blocking the path of condensation leakage from the connection gap. The condensation after confluence flows into the siphon valve 24 fixedly installed at the bottom of the outer shell 21. The inner hole of the connecting flange 25 is coaxially set with the drainage channel of the siphon valve 24 to ensure that the condensation flows without obstruction. At the same time, the siphon valve 24 can block the siphon backflow phenomenon and ensure the condensation flows stably in one direction.

[0022] The condensate flows through the siphon valve 24 into the bottom detachable drain elbow 26. The drain elbow 26 can flexibly change the drainage direction to adapt to different installation space layouts. Then the condensate enters the straight pipe 31 of the drainage assembly 3. When the condensate flows in the straight pipe 31, it will drive the rotating shaft 33 and the scraper blades 34 evenly distributed on the outer surface to rotate synchronously. The bearing 36 can reduce the frictional resistance when the rotating shaft 33 rotates, the fixing block 32 provides a stable installation support for the bearing 36, and the scraper blades 34 scrape the inner wall of the straight pipe 31 during rotation to prevent impurities from adhering and causing pipe blockage.

[0023] Finally, the condensate, after being cleaned on the inner wall, is smoothly discharged from the device through the bend 35, which is detachably connected to the other end of the straight pipe 31, following a preset path. This completes the entire process of condensate production, collection, sealing and leak prevention, backflow prevention, self-cleaning, and discharge for the low static pressure duct air conditioner, ensuring stable operation of the equipment.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
