Description

Technical Field

[0001] This utility model relates to the field of air handling units, specifically a drainage mechanism for air handling units. Background Technology

[0002] Air Handling Unit (AHU): An air handling unit (AHU) is a centralized air handling system. It originated from a centralized equipment installation and a forced hot air heating and ventilation system that distributes heated air through ducts. The basic centralized system is a single-zone all-air system, which generally includes components such as a fan, heater, cooler, and filter. When cooling or dehumidifying, condensate will form on the heat exchange unit of the heat exchange mechanism. When a certain amount of condensate is reached, it will fall into the drip tray at the bottom. The drip tray is equipped with grooves, and the condensate slowly flows into the grooves and then is discharged from the drain pipe connected to the bottom of the grooves.

[0003] Patent application number 20202222641.7 discloses a drainage mechanism for an air handling unit and an air handling unit, relating to the field of refrigeration and air conditioning technology. The drainage mechanism for the air handling unit includes: a water receiving tray for receiving condensate, the water receiving tray having a groove and a drain outlet at the bottom of the groove; a drain pipe connected to the drain outlet, the drain pipe having threads on its side wall; and a base mechanism for supporting the water receiving tray, the base mechanism having a fixing member with an opening, the fixing member having an opening into which the drain pipe extends. This application can effectively ensure that the water in the water receiving tray and the groove can be fully discharged through the drain pipe.

[0004] However, in practical applications, traditional drip trays cannot guarantee that the drain outlet is located at the lowest point of the drip tray due to different installation site conditions. Over a long period of use, condensate can easily accumulate on the drip tray, making drainage inconvenient, leading to bacterial growth and affecting air treatment. For example, when installing the water collection tray, due to the different installation sites and locations of the air handling components, the drain outlet may not be located at the lowest point of the water collection tray, resulting in untimely drainage, water accumulation, and thus affecting drainage. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a drainage mechanism for air handling units. This addresses the technical problem that, due to different installation site conditions, it is impossible to ensure that the drain outlet is located at the lowest point of the water tray. During long-term use, condensate easily accumulates on the water tray, making drainage inconvenient, leading to bacterial growth, and affecting air handling.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a drainage mechanism for an air handling unit is designed, including a base, two reinforcing rods are symmetrically fixed between the two bases, a water receiving tray is connected to the top of the two bases, a drainage groove is opened in the middle of the bottom of the water receiving tray, a first drainage pipe is fixed through the bottom edge of the drainage groove, an adjustment component is connected to the bottom of the water receiving tray, and a disassembly component is provided on the outside of the water receiving tray.

[0007] In this solution, the position of the receiving tray can be adjusted by adjusting the components, so that the first drain pipe is located at the lowest point of the receiving tray, which facilitates drainage, avoids condensation residue, and prevents bacterial growth. The disassembly and assembly components make it easy to disassemble the placement tray inside the receiving tray, which is convenient for cleaning and prevents bacteria growth after long-term use.

[0008] Preferably, the adjusting assembly includes a fixing plate fixed to the top edge of the base, rotating shafts fixed to both sides of the water receiving tray, a screw rod rotatably passing through the middle between the opposite sides of the two reinforcing rods, a turntable fixed to one end of the screw rod, a fastening bolt threaded through one side of the turntable, limit rods symmetrically fixed between the opposite sides of the two reinforcing rods, a slider threaded to the outer wall of the screw rod, a mounting base fixed to the top center of the slider, a connecting rod rotatably connected inside the mounting base, and a connecting seat fixed to the bottom edge of the water receiving tray.

[0009] In practical applications, rotating the turntable drives the screw to rotate, causing the slider to move outside the limit rod, which in turn moves the mounting base, causing the connecting rod to deflect and lift the connecting base, thus deflecting the water tray. This keeps the rotating shaft inside the fixed plate, placing the first drain pipe at the lowest point of the water tray for easy and rapid drainage. This prevents condensate from accumulating inside the water tray, thus preventing bacterial growth and avoiding any impact on air handling.

[0010] Preferably, the rotating shaft passes through one side of the fixed plate and is rotatably connected to its interior.

[0011] In practical applications, it facilitates the deflection of the water receiving tray.

[0012] Preferably, one end of the connecting rod rotates inside the connecting seat, and the slider slides outside the limiting rod.

[0013] In practical applications, when the screw rotates, the limiting rod is used to limit the slider, so that the slider moves stably outside the limiting rod, thereby moving the mounting base and causing the connecting rod to deflect.

[0014] Preferably, the disassembly and assembly assembly includes a connecting block fixed to the top of the base, a slot extending through the top edge of the connecting block, an installation cavity formed in the middle of one side of the slot, a return spring fixed in the middle of one side of the installation cavity, a movable plate fixed to one end of the return spring, a locking block fixed in the middle of one side of the movable plate, a placement plate connected inside the water receiving tray, a second drain pipe extending through the bottom edge of the placement plate, L-shaped plates symmetrically fixed to the top of the placement plate, and a locking groove extending through one side of the L-shaped plate.

[0015] In practical applications, by pulling the L-shaped plate, the slot is pressed against the inclined surface at the bottom of the card block, causing the card block to move and thus move out of the slot, allowing the placement tray to be disassembled. During installation, the L-shaped plate is inserted into the slot, pressing against the inclined surface at the top of the card block, causing the card block to move. When the card block is aligned with the slot, the return spring resets the card block, making it embedded in the slot, thus completing the installation. This facilitates the disassembly and cleaning of the placement tray, prevents the growth of bacteria and moss, ensures cleanliness, and avoids affecting air handling.

[0016] Preferably, the movable plate slides inside the mounting cavity, and the outer sidewall of the movable plate is in contact with the inner sidewall of the mounting cavity.

[0017] In practical applications, limiting the movement of the movable plate facilitates its stable movement within the mounting cavity.

[0018] Preferably, the upper and lower sides of the card block are provided with inclined surfaces, and the second drain pipe is located inside the first drain pipe.

[0019] In practical applications, pressing the inclined surface of the card block facilitates its movement.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adjusts the component settings, rotates the turntable to drive the screw to rotate, causing the slider to move outside the limit rod, driving the mounting base to move, thereby causing the connecting rod to deflect, which in turn lifts the connecting base, causing the water receiving tray to deflect, so that the rotating shaft is inside the fixed plate, and the first drain pipe is located at the lowest point of the water receiving tray, which facilitates rapid drainage, avoids the accumulation of condensate inside the water receiving tray, prevents the growth of bacteria, and avoids affecting air treatment; 2. This utility model, through the setting of the disassembly and assembly mechanism, uses the L-shaped plate to pull the slot to press the inclined surface at the bottom of the card block, causing the card block to move and thus move out of the slot, allowing the placement tray to be disassembled. During installation, the L-shaped plate is inserted into the slot, pressing the inclined surface at the top of the card block to move the card block. When the card block is aligned with the slot, the reset spring returns the card block to the slot, completing the installation. This facilitates the disassembly and cleaning of the placement tray, prevents the growth of bacteria and moss, ensures cleanliness, and avoids affecting air handling. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A drainage mechanism for an air handling unit, see [link to example]. Figures 1 to 5The device includes a base 1, with reinforcing rods symmetrically fixed between the two bases 1. A water receiving tray 3 is connected to the top of the two bases 1.

An adjusting component 4 is connected to the bottom of the water receiving tray 3, and a disassembly / removal component 5 is provided on the outside of the water receiving tray 3. The adjusting component 4 allows for easy adjustment of the position of the water receiving tray 3, ensuring the first drain pipe 302 is positioned at the lowest point of the water receiving tray 3 for easy drainage, preventing condensation residue and bacterial growth. The disassembly / removal component 5 allows for easy disassembly of the placement tray 507 inside the water receiving tray 3, facilitating cleaning and preventing bacterial growth over prolonged use. For details, see Figure 3 The adjusting assembly 4 includes a fixing plate 401 fixed to the top edge of the base 1, a rotating shaft 402 fixed to both sides of the water receiving tray 3, a screw 403 rotatably passing through the middle between the opposite sides of the two reinforcing rods 2, a turntable 404 fixed to one end of the screw 403, a fastening bolt 405 screwed through one side of the turntable 404, limit rods 406 symmetrically fixed between the opposite sides of the two reinforcing rods 2, a slider 407 screwed to the outer wall of the screw 403, a mounting base 408 fixed to the top center of the slider 407, a connecting rod 409 rotatably passing through the mounting base 408, and a connecting seat 410 fixed to the bottom edge of the water receiving tray 3; the rotating shaft 402 passes through the fixing plate 401. The plate 401 is rotatably connected to one side of the plate 401; one end of the connecting rod 409 rotates inside the connecting seat 410, and the slider 407 slides outside the limiting rod 406; by rotating the turntable 404, the screw 403 is driven to rotate, causing the slider 407 to move outside the limiting rod 406, driving the mounting seat 408 to move, thereby causing the connecting rod 409 to deflect, which in turn lifts the connecting seat 410, causing the water receiving tray 3 to deflect, so that the rotating shaft 402 is inside the fixed plate 401, and the first drain pipe 302 is located at the lowest point of the water receiving tray 3, which facilitates rapid drainage, avoids the accumulation of condensate inside the water receiving tray 3, prevents the growth of bacteria, and avoids affecting air treatment.

[0028] It is worth noting that, see Figure 4 and Figure 5The assembly 5 includes a connecting block 501 fixed to the top of the base 1. A slot 502 is provided through the top edge of the connecting block 501. An installation cavity 503 is provided in the middle of one side of the slot 502. A return spring 504 is fixed in the middle of one side of the installation cavity 503. A movable plate 505 is fixed to one end of the return spring 504.

The upper and lower sides of the locking block 506 are provided with inclined surfaces, and the second drain pipe 508 is located inside the first drain pipe 302. By pulling the L-shaped plate 509, the locking groove 510 is pressed against the inclined surface at the bottom of the locking block 506, causing the locking block 506 to move and thus move the locking block 506 out of the locking groove 510, allowing the placement tray 507 to be disassembled. During installation, by inserting the L-shaped plate 509 into the slot 502, the inclined surface at the top of the locking block 506 is pressed, causing the locking block 506 to move. When the locking block 506 is aligned with the locking groove 510, the reset spring 504 resets the locking block 506, allowing it to be embedded in the locking groove 510, completing the installation. This facilitates the disassembly of the placement tray 507, makes it easy to clean the placement tray 507, prevents the growth of bacteria and moss, ensures cleanliness, and avoids affecting air treatment.

[0029] In practical use, when debugging the device, rotating the turntable 404 causes the water receiving tray 3 to deflect, thereby placing the first drain pipe 302 at the lowest point, which facilitates the rapid discharge of condensate and prevents its accumulation.
