Description

Technical Field

[0001] This invention relates to the field of air conditioning unit equipment technology, specifically to a modular air conditioning unit condensate tray and its installation system. Background Technology

[0002] An air conditioning unit is an air handling device assembled from various air handling functional sections. The air handling functional sections of the unit include units such as air mixing, flow equalization, filtration, cooling, dehumidification, humidification, and air supply. In summer, the amount of condensate produced in the air conditioning unit every day is huge, and the condensate is low in temperature, has few impurities, and low in hardness, so it has high recycling value. The condensate pan is used for the collection and discharge of condensate.

[0003] In the Chinese patent with publication number CN215175912U, entitled "A Novel Condensate Pan for an Air Conditioning Unit", the patent uses a locking mechanism to fix the condensate pan to the bottom of the air conditioning unit. When the condensate pan needs to be disassembled, simply press the pressing blocks on both sides of the bottom of the locking device inward at the same time so that the pressing blocks can pass through the slot, thereby releasing the fixation of the condensate pan. The design of this structure is convenient to operate and easy to disassemble. The condensate trays in this patent and existing technologies need to be specially customized according to the size of the air conditioning unit. Different sized condensate trays cannot be used for air conditioning units of different sizes, resulting in a limited range of applicability. Furthermore, when a large-volume tray is damaged, the entire tray needs to be disassembled, making maintenance inconvenient. In addition, when the drain pipe of the existing condensate tray is blocked, the condensate produced by the air conditioning unit can easily overflow from the inside of the tray, polluting the working environment. Summary of the Invention

[0004] This invention provides a modular air conditioning unit condensate tray and its installation system, which can effectively solve the problems in the prior art mentioned above, such as the inability of the condensate tray to be used with air conditioning units of different sizes, the limited applicability of the tray, the inconvenience of maintenance, and the easy overflow of condensate from the air conditioning unit from the inside of the tray when the drain pipe of the existing condensate tray is blocked, thus polluting the working environment.

[0006] According to the above technical solution, there are three discs arranged closely together. One side of the trapezoidal head is connected to a pull rod between two fixed springs. The top of the pull rod passes through the fixed box and is connected to a pull plate.

The fixed side plates are also welded with splicing pipes at both ends. The splicing pipes have fixing openings on both sides, and the trapezoidal head is inserted into the splicing pipe through the adjacent fixing opening.

[0008] According to the above technical solution, the H-shaped frame is welded with U-shaped clamps at both ends, and the top of both ends of the enclosure is provided with positioning slots. The U-shaped clamps are snapped onto the outside of the positioning slots, and a positioning plate is welded to one side of the U-shaped clamps.

[0009] According to the above technical solution, the bottom of the siphon pipe is connected to an overflow pipe, one end of the enclosure is connected to one end of a drain connector, the other end of the drain connector is connected to a drain pipe, one end of the overflow pipe and the drain pipe are connected to one side of a collection pipe, and the top of the collection pipe is connected to a recycling tank.

[0010] According to the above technical solution, the bottom of the recycling tank is connected to a recycling pipe via an electrically controlled valve, the input end of the electrically controlled valve is electrically connected to the output end of an external power supply via a controller, and an overflow prevention pipe is connected to the top of one side of the recycling tank.

[0011] According to the above technical solution, a plurality of movable rollers are installed on the top inner side of the support frame, and the bottom of the movable rollers is in contact with the top surface of the support square tube.

[0012] According to the above technical solution, a fixing and installation component is provided on the outside of the supporting square tube, and the fixing and installation component includes an assembly hole; The top of one end of the supporting square tube is provided with an assembly hole, and the other end of the supporting square tube is connected to an embedded tube. An assembly head is slidably connected to the top of the embedded tube. The bottom of the assembly head is connected to the bottom surface of the inner tube through an assembly spring. The assembly head is embedded in the adjacent assembly hole. The supporting square tube has multiple assembly holes evenly spaced on both sides. Multiple C-shaped brackets are fixed to the outside of the supporting square tube. Fixing screws are connected inside the C-shaped brackets and pass through the corresponding assembly holes. An outer sleeve is connected to the top of the C-shaped bracket. An inner sleeve is slidably connected inside the outer sleeve. The inner sleeve and the outer sleeve are connected by a tensioning spring. A tensioning lug is welded to the top of the inner sleeve. A fixing clip is provided at the top of the tensioning lug.

[0013] According to the above technical solution, the bottom ends of the supporting square tube are connected to supporting screws through screw holes, and the bottom of the supporting screws is connected to supporting foot plates through universal joints.

[0014] According to the above technical solution, the two opposing supporting square tubes are connected by an assembly rod, and a pair of assembly holes are passed through each end of the assembly rod. The two ends of the assembly rod are fixed to the supporting square tube by wing nuts.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with an anti-overflow assembly component, the tray is composed of multiple connected tray modules, which can be flexibly assembled as needed to meet the requirements of different types of air conditioners, making it widely applicable. During assembly, the interlocking between the components allows for quick assembly of multiple trays, making assembly simple and convenient. For subsequent maintenance, simply use the pull plate to remove the trapezoidal head from the splicing pipe, remove the splicing frame and splicing pipe, and then remove the concave sleeve and fixed side plate to disassemble a single tray. Cleaning and maintenance are convenient. The splicing frame, splicing pipe, and trapezoidal head work together to assist in tray installation and strengthen the assembly of the tray, making the installation more secure. When the drain connector is blocked, if the water level slowly submerges the top of the siphon tube, the water above the top of the siphon tube will slowly flow from the inside of the siphon tube into the overflow pipe, and the condensate will not overflow from the pan. If the water level rises quickly and fills the inside of the siphon tube and the inside of the siphon cylinder, the air inside the siphon tube will be quickly squeezed out by the water. The pressure inside the siphon tube is less than the external pressure, and a siphon effect is formed under the action of the pressure difference. By increasing the drainage channel and utilizing the siphon effect, the overflow of condensate due to the blockage of the drain connector is prevented, the drainage effect is optimized, and the unit failure caused by the accumulation of condensate is avoided. The positioning rod is inserted into the bottom of the splicing pipe. Multiple moving rollers are installed on the top of the inner side of the support frame. The bottom of the moving rollers is in contact with the top surface of the support square tube. After the support frame and positioning rod support and fix the plate, the plate can move smoothly on the top of the support square tube under the support of the moving rollers. This makes it easy for the plate to be accurately aligned with the bottom of the air conditioning unit condenser. The debugging is simple and convenient, further reducing the installation difficulty. The condensate produced by the recycling tank can be stored, and the stored condensate can be discharged by controlling the switch of the electronic valve. The discharged condensate can be recycled and reused, making it more environmentally friendly.

[0016] 2. Equipped with a fixed installation component, when the tray is exposed outdoors, align the fixing screw with the mounting hole, fix the U-shaped frame, pull the inner sleeve, and snap the fixing clip onto the top of the enclosure. Under the tension of the tightening spring, the tray can be stably fixed on the top of the supporting square tube. In strong winds, this prevents the tray from detaching from the supporting square tube, ensuring the installation stability of the tray. The positioning slot can limit the lateral movement of the U-shaped clamp, preventing the siphon cylinder from moving laterally. The two ends of the positioning plate are located at the bottom of the tightening ears. When the fixing clip is snapped onto the top of the enclosure, the tightening ears can limit the top of the positioning plate, ensuring the stable fixation of the siphon cylinder in strong winds. When the tray is not exposed outdoors, there is no need to install the U-shaped frame, outer sleeve, inner sleeve, tightening ears, and fixing clip, making it highly flexible in use. The bottom of the support screw is connected to the support foot plate via a universal joint. Rotating the support screw can change the horizontal height of the support square tubes on both sides. After all components are installed, rotating the support screw changes the horizontal height of the support square tubes on both sides. Under the connection of the universal joint, the disc tilts towards the drain connector, so that the support square tube on the drain connector side is in a lower position, which facilitates the smooth discharge of condensate.

[0017] In summary, each tray module in the assembled anti-overflow assembly has an independent drainage channel and is designed with a siphon pipe and siphon cylinder to prevent overflow, effectively preventing condensate from overflowing and ensuring environmental hygiene during unit operation. Furthermore, each tray is flexibly connected and fixed via adjustable connectors such as L-shaped rails, concave sleeves, trapezoidal heads, fixing springs, splicing frames, and splicing pipes. These components, along with the embedded pipes, splicing heads, and splicing holes in the fixed installation assembly, work together to improve the ease of installation and applicability of the overall tray. The two components work together to stably fix the tray, enhancing its installation stability. Attached Figure Description

L-shaped rails 202 are provided on both sides of the bottom of the disc body 1. A concave sleeve 203 is slidably fitted onto the outer sides of two adjacent L-shaped rails 202. Fixing boxes 204 are welded to both ends of the surrounding plate 201. A trapezoidal head 205 is slidably connected inside the fixing box 204. One side of the trapezoidal head 205 is connected to one side of the fixing box 204 via two fixing springs 206. A pull rod 207 is connected to one side of the trapezoidal head 205 between the two fixing springs 206. The top of the pull rod 207 passes through the fixing box 204 and is connected to a pull plate 208. Under the action of the pull rod 207, holding the pull plate 208 can pull the trapezoidal head 205, allowing two adjacent disc bodies 1 to move. A splicing frame 209 is inverted at the top of the splicing joint. Splicing pipes 210 are welded to both ends of the splicing frame 209. The longitudinal section of the splicing frame 209 is inverted U-shaped. The splicing frame 209 is inverted at the top of the splicing joint of two adjacent panels 201. When the concave sleeve 203 is installed on the outside of two adjacent L-shaped rails 202, it will fix the bottom of the joint of the two panels 1. After the splicing pipe 210 is installed, the splicing frame 209 will fix the top of the joint of the two panels 1. The splicing frame 209 and the concave sleeve 203 cooperate to fix the top and bottom of the joint of the two panels 1. The splicing frame 209 can seal the joint of the two panels 1 to prevent the condensate of the air conditioner from seeping into the joint. Two outer discs 1 are connected to fixed side plates 212 via L-shaped rails 202 on their outer sides. Splicing pipes 210 are welded to both ends of the fixed side plates 212. Fixing openings 211 are provided on both sides of the splicing pipes 210. Trapezoidal heads 205 penetrate adjacent fixing openings 211 and are embedded inside the splicing pipes 210. During installation, the splicing pipes 210 will press down on the inclined surfaces of the trapezoidal heads 205 from top to bottom. Under this pressure, the trapezoidal heads 205 will first move into the fixing box 204, compressing the fixing spring 206. When the splicing pipes 210 and the splicing frame 209... After installation, the trapezoidal head 205 aligns with the fixing port 211, the trapezoidal head 205 is no longer restricted, the fixing spring 206 rebounds, and the trapezoidal head 205 is embedded inside the splicing pipe 210. At this time, the splicing pipe 210 is fixed by the trapezoidal head 205 and cannot move. The trapezoidal head 205 and the splicing pipe 210 work together to fix the two ends of the joint of the two discs 1. With the limiting effect of the splicing frame 209 and the concave sleeve 203, the two adjacent discs 1 are stably fixed. When disassembling, the trapezoidal head 205 can be moved out of the splicing pipe 210 by holding the pull plate 208. A siphon tube 213 is connected to the middle of the inner side of the disc body 1. An H-shaped frame 214 is attached to the top of the surrounding plate 201. A siphon cylinder 215 is connected to the middle of the bottom of the H-shaped frame 214. The siphon cylinder 215 is upside down on the top of the siphon tube 213. U-shaped clamps 216 are welded to both ends of the H-shaped frame 214. Positioning slots 218 are opened at the top of both ends of the surrounding plate 201. The U-shaped clamps 216 are snapped onto the outside of the positioning slots 218. A positioning plate 217 is welded to one side of the U-shaped clamps 216. The positioning slots 218 facilitate the positioning of the U-shaped clamps 216, so that the siphon cylinder 215 is accurately upside down on the top of the siphon tube 213, making the installation of the siphon cylinder 215 more convenient. The positioning slots 218 can limit the lateral movement of the U-shaped clamps 216 to prevent the siphon cylinder 215 from moving laterally. Multiple supporting square tubes 227 are provided on both sides of the bottom of the tray 1. The two adjacent supporting square tubes 227 are connected end to end. Multiple supporting frames 228 are placed on the top of the supporting square tubes 227. Positioning rods 230 are welded to the top of the supporting frames 228. The top of the positioning rods 230 is embedded in the bottom of the inner side of the adjacent splicing pipes 210. After all the trays 1 are assembled and fixed, the supporting frames 228 are placed on the top of the supporting square tubes 227. The position of the supporting frames 228 is moved so that the positioning rods 230 are aligned with the splicing pipes 210. The positioning rods 230 are inserted into the bottom of the splicing pipes 210 to complete the installation of the tray on the top of the supporting square tubes 227. Multiple moving rollers 229 are installed on the top of the inner side of the supporting frames 228. The bottom of the moving rollers 229 is in contact with the top surface of the supporting square tubes 227. After the supporting frames 228 and the positioning rods 230 support and fix the tray 1, the tray 1 can move smoothly on the top of the supporting square tubes 227 under the support of the moving rollers 229, which facilitates the adjustment of the position of the tray 1. The bottom of the siphon pipe 213 is connected to the overflow pipe 219. One end of the enclosure 201 is connected to one end of the drain connector 220. The other end of the drain connector 220 is connected to the drain pipe 221. One end of the overflow pipe 219 and the drain pipe 221 are connected to one side of the collection pipe 222. The top of the collection pipe 222 is connected to the recovery tank 223. The bottom of the recovery tank 223 is connected to the recovery pipe 224 through the electric control valve 225. The input end of the electric control valve 225 is electrically connected to the output end of the external power supply through the controller. The condensate produced by the recovery tank 223 is stored. The condensate stored inside the recovery tank 223 can be discharged by controlling the opening and closing of the electric control valve 225. The discharged condensate can be recycled. The top of one side of the recovery tank 223 is connected to the anti-overflow pipe 226. Water that cannot be stored in the recovery tank 223 will be discharged from the anti-overflow pipe 226 into the drain pipe to prevent the condensate from flowing everywhere. like Figure 8-12 As shown, the present invention provides an installation system for a modular air conditioning unit condensate tray. A fixed installation component 3 is provided on the outside of the supporting square tube 227. The fixed installation component 3 includes an assembly hole 301, an inner tube 302, an assembly head 303, an assembly spring 304, an assembly hole 305, a fixing screw 306, a C-shaped bracket 307, an outer tube 308, an inner tube 309, a tightening spring 310, a tightening lug 311, a fixing clamp 312, a supporting screw 313, a universal joint 314, a supporting foot plate 315, an assembly rod 316, and a wing nut 317. The top of one end of the supporting square tube 227 is provided with an assembly hole 301, and the other end of the supporting square tube 227 is connected to an inner tube 302. An assembly head 303 is slidably connected to the top of the inner tube 302. The bottom of the assembly head 303 is connected to the bottom surface inside the inner tube 302 through an assembly spring 304. The assembly head 303 is embedded in the adjacent assembly hole 301. Multiple mounting holes 305 are evenly spaced on both sides of the supporting square tube 227. Multiple C-shaped brackets 307 are fixed to the outside of the supporting square tube 227. Fixing screws 306 are connected inside the C-shaped brackets 307 and pass through the corresponding mounting holes 305. An outer sleeve 308 is connected to the top of the C-shaped brackets 307. An inner sleeve 309 is slidably connected inside the outer sleeve 308. The inner sleeve 309 and the outer sleeve 308 are connected by a tensioning spring 310. A tensioning lug 311 is welded to the top of the inner sleeve 309. A fixing clip 312 is provided at the top of the tightening ear 311. The fixing clip 312 is snapped onto the top of the adjacent enclosure 201. The two ends of the positioning plate 217 are located at the bottom of the tightening ear 311. When the fixing clip 312 is snapped onto the top of the enclosure 201, under the tension of the tightening spring 310, the disc 1 can be stably fixed on the top of the supporting square tube 227. The tightening ear 311 can limit the top of the positioning plate 217 to prevent the U-shaped clamp 216 from dislodging from the positioning slot 218, thereby achieving stable fixation of the siphon cylinder 215. Support screws 313 are connected to the bottom ends of the support square tube 227 through screw holes. Support foot plates 315 are connected to the bottom of the support screws 313 through universal joints 314. Rotating the support screws 313 can change the horizontal height of the support square tubes 227 on both sides. After all components are installed, rotating the support screws 313 changes the horizontal height of the support square tubes 227 on both sides. Under the connection of the universal joints 314, the disc 1 tilts towards the drain connector 220, so that the support square tube 227 on the drain connector 220 side is in a lower position, which facilitates the smooth discharge of condensate. The two opposing support square tubes 227 are connected by an assembly rod 316. The two ends of the assembly rod 316 are respectively through a pair of assembly holes 301. The two ends of the assembly rod 316 are fixed to the support square tubes 227 by wing nuts 317. The assembly rod 316 can connect and fix the support square tubes 227 on both sides, so that the support square tubes 227 on both sides are in a stable parallel state.

[0022] The working principle and usage process of this invention are as follows: First, the supporting square tubes 227 are assembled. During assembly, the assembly head 303 is pressed, and the assembly spring 304 is compressed. The inner tube 302 at one end of one supporting square tube 227 is inserted into the corresponding internal position of the assembly hole 301 of another supporting square tube 227. When the assembly head 303 moves to the position of the assembly hole 301, the assembly spring 304 rebounds. Under the limiting action of the assembly head 303, the assembly and fixing of the two supporting square tubes 227 is completed. This operation is repeated to complete the assembly and fixing of the other two supporting square tubes 227. Then, the assembly rod 316 is moved to the middle of the two assembled tubes, and the two ends of the assembly rod 316 are passed through the corresponding assembly holes 305 and fixed with the wing nut 317. The supporting square tubes 227 on both sides are parallel and stablely fixed by the connection of the assembly rod 316. Next, the two panels 1 are joined together, and the concave sleeve 203 is slidably installed on the outside of the two adjacent L-shaped rails 202. The bottom of the joint between the two panels 1 is fixed by the connection of the concave sleeve 203. Then, holding the splicing frame 209, the splicing frame 209 is aligned with the top of the joint between the two panels 1, and the splicing frame 209 and the splicing pipe 210 are installed. The splicing frame 209 is inverted and placed on the top of the joint between the two adjacent side panels 201 to fix the top of the joint between the two panels 1. The splicing frame 209 can also seal the joint between the two panels 1 to prevent condensate from the air conditioner from seeping into the joint. During the installation process, the splicing pipe 210 is pressed from top to bottom against the inclined surface of the trapezoidal head 205. Under the pressure, the trapezoidal head 205 will first move into the fixing box 204, and the fixing spring 206 will be compressed. After the splicing pipe 210 and the splicing frame 209 are installed, When the trapezoidal head 205 is aligned with the fixing port 211, the trapezoidal head 205 loses its restriction, the fixing spring 206 rebounds, and the trapezoidal head 205 is embedded inside the splicing pipe 210. At this time, the splicing pipe 210 is fixed by the trapezoidal head 205 and cannot move. The trapezoidal head 205 and the splicing pipe 210 work together to fix the two ends of the joint of the two discs 1. The splicing pipe 210 can block the two ends of the concave sleeve 203 to prevent the concave sleeve 203 from falling off the outside of the L-shaped rail 202. With the limiting effect of the splicing frame 209 and the concave sleeve 203, the two adjacent discs 1 are tightly connected and fixed. When assembling the third disc 1, the above steps are repeated. After the three discs 1 are assembled, the fixing side plate 212 is installed on one side of the two outermost discs 1. The splicing pipes 210 at both ends of the fixing side plate 212 only serve as support and fixation to facilitate the subsequent docking of the positioning rod 230. The tray is composed of multiple tray body 1 modules connected together, which can be flexibly assembled as needed to meet the needs of different types of air conditioners. It has a wide range of applications. During assembly, the interlocking between the components completes the quick assembly of multiple tray bodies 1. The assembly is simple and convenient. When it is necessary to disassemble the tray body 1 for subsequent maintenance, the trapezoidal head 205 is moved out of the splicing pipe 210 by holding the pull plate 208, the splicing frame 209 and the splicing pipe 210 are removed, and then the concave sleeve 203 and the fixed side plate 212 are removed. Cleaning and maintenance are convenient. After all the trays 1 are assembled and fixed, the support frame 228 is placed on top of the support square tube 227. The position of the support frame 228 is moved so that the positioning rod 230 is aligned with the splicing pipe 210. The positioning rod 230 is inserted into the bottom of the splicing pipe 210 to complete the installation of the tray on top of the support square tube 227. Multiple moving rollers 229 are installed on the top inner side of the support frame 228. The bottom of the moving rollers 229 is in contact with the top surface of the support square tube 227. After the support frame 228 and the positioning rod 230 support and fix the tray 1, the tray 1 can move smoothly on top of the support square tube 227 under the support of the moving rollers 229. This makes it easy to adjust the position of the tray 1 and make it easy to accurately align the tray 1 with the bottom of the air conditioning unit condenser. The debugging is simple and convenient, further reducing the installation difficulty. Next, holding the H-shaped frame 214, the U-shaped clamp 216 is snapped onto the outside of the positioning slot 218. The positioning slot 218 positions the U-shaped clamp 216, thus accurately placing the siphon cylinder 215 upside down on top of the siphon tube 213, making the installation of the siphon cylinder 215 more convenient. When the drain connector 220 becomes blocked, the water level of the condensate inside the disc 1 rises. When the water level slowly submerges the top of the siphon tube 213, the water above the top of the siphon tube 213 will slowly flow from inside the siphon tube 213 into the overflow pipe 219. The recovery tank 223 is located at the bottom of the disc 1, and the water inside the overflow pipe 219 will flow into the recovery tank 223. Since the top surface of the siphon tube 213 is lower than the top surface of the surrounding plate 201, the condensate will not overflow from the disc 1, and the slowly rising condensate will not fill the inside of the siphon tube 213. The gap between the inside of the siphon tube 213 and the outside of the siphon tube 215 is filled. At this time, the pressure inside the siphon tube 213 is equal to that outside, and no siphon effect occurs. When the water level rises quickly and fills the inside of the siphon tube 213 and the inside of the siphon tube 215, the air inside the siphon tube 213 is quickly squeezed out by the water. The pressure inside the siphon tube 213 is less than the external pressure. Under the action of the pressure difference, a siphon effect is formed. The water inside the pan 1 will quickly enter the siphon tube 213 from the bottom of the siphon tube 215 and be discharged from the pan 1 until the water level is level with the bottom of the siphon tube 215. The siphon effect stops. In summary, no matter how slowly or quickly the condensate water level rises, the water inside the pan 1 will not overflow, preventing condensate water from overflowing due to blockage of the drain connector 220. This optimizes the drainage effect and avoids unit failure caused by condensate water accumulation. Condensate can enter the recovery tank 223 from the overflow pipe 219, drain pipe 221 and collection pipe 222. The condensate produced in the recovery tank 223 is stored. The condensate stored in the recovery tank 223 can be discharged by controlling the switch of the solenoid valve 225. The discharged condensate can be recycled. An overflow prevention pipe 226 is connected to the top of one side of the recovery tank 223. Water that cannot be stored in the recovery tank 223 will be discharged from the overflow prevention pipe 226 into the drain pipe to prevent condensate from flowing everywhere. Support screws 313 are connected to the bottom ends of the support square tube 227 through screw holes. Support foot plates 315 are connected to the bottom of the support screws 313 through universal joints 314. Rotating the support screws 313 can change the horizontal height of the support square tubes 227 on both sides. After all components are installed, rotating the support screws 313 changes the horizontal height of the support square tubes 227 on both sides. Under the connection of the universal joints 314, the disc 1 tilts towards the drain connector 220, so that the support square tube 227 on the drain connector 220 side is in a lower position, which facilitates the smooth discharge of condensate. When the tray is exposed outdoors, the fixing screw 306 can be aligned with the mounting hole 305 to fix the U-shaped bracket 307. Pulling the inner sleeve 309 will snap the fixing clamp 312 onto the top of the enclosure 201. Under the tension of the spring 310, the tray 1 can be stably fixed to the top of the supporting square tube 227. In strong winds, this prevents the tray 1 from detaching from the supporting square tube 227, ensuring the installation stability of the tray 1. Furthermore, the positioning slot 218 can limit the lateral movement of the U-shaped clamp 216, preventing... To prevent the siphon cylinder 215 from moving laterally, the two ends of the positioning plate 217 are located at the bottom of the tightening ear 311. When the fixing clip 312 is snapped onto the top of the enclosure 201, the tightening ear 311 can limit the top of the positioning plate 217. In strong winds, this ensures the stable fixation of the siphon cylinder 215. When the tray is not exposed outdoors, there is no need to install the fixing screw 306, the C-shaped frame 307, the outer sleeve 308, the inner sleeve 309, the tightening spring 310, the tightening ear 311, and the fixing clip 312, making it highly flexible in use. In the assembly anti-overflow component 2, each panel 1 module has an independent drainage channel and is designed with a siphon pipe 213 and a siphon cylinder 215 to prevent overflow. This effectively prevents condensate from overflowing, ensuring environmental hygiene during unit operation and avoiding unit malfunctions caused by condensate accumulation. Each panel 1 is flexibly connected and fixed by adjustable connectors such as L-shaped rails 202, concave sleeves 203, trapezoidal heads 205, fixing springs 206, splicing frames 209, and splicing pipes 210. These connectors work together with the embedded pipes 302, splicing heads 303, and splicing holes 301 in the fixed installation component 3. This not only improves the ease of installation but also allows the entire tray to be flexibly assembled according to the size of the air conditioning unit, making it widely applicable and highly practical.
