[0001] This utility model relates to the field of air conditioning technology, and in particular to a drainage structure for a wall-mounted air conditioner. Background Technology
[0002] Currently, the drain outlets of air-conditioning systems with wall structures are vertically downward, making it inconvenient to install condensate drain pipes during the engineering phase. This leads to difficulties in installation, or the condensate drain hoses becoming unreliable, resulting in leaks. This also makes frontal maintenance impossible, causing difficulties in later maintenance. Utility Model Content
[0003] The purpose of this utility model is to solve the shortcomings of existing air-wall structure air conditioners where the drain outlet is vertically downward, making it inconvenient to install condensate drain pipes during the engineering stage, resulting in difficult installation operations, or the condensate drain hose being unreliable, leading to water leakage, making it impossible to achieve front-side maintenance operations, and causing difficulties in later maintenance. The present invention provides a drainage structure for air-wall air conditioners.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a drainage structure for a wall-mounted air conditioner, which is set at the bottom of the heat exchanger in the unit, including a water receiving tray, a drain pipe communicating with the water receiving tray, and an external drainage component communicating with the drain pipe; a maintenance plate is set in the unit at the external drainage component, the maintenance plate is detachably connected to the unit, the end of the drain pipe is fixed to the bottom of the water receiving tray by a fastening component, the front end of the drain pipe is parallel to the bottom of the unit, and the external drainage component is connected to the end of the drain pipe by a connecting component. By detachably connecting the maintenance plate to the unit and placing it at the external drainage component, operators can easily connect the external drainage component to the drain pipe via the connecting component after removing the maintenance plate. This significantly improves the ease of installation and replacement of the external drainage component, preventing leaks. Furthermore, by aligning the front end of the drain pipe parallel to the bottom of the unit, the external drainage component can be connected to the front of the unit, allowing for maintenance from the front and further enhancing the convenience of subsequent maintenance.
[0005] Furthermore, the drain pipe is an L-shaped drain pipe, including a vertically arranged connecting section communicating with the water receiving tray and a drain section communicating with the external drain assembly, with the fastening component disposed on the drain section. In the embodiment provided by this utility model, the drain section is parallel to the bottom of the unit, so that after the external drain assembly is connected to the drain section of the drain pipe through the connecting component, the end of the external drain assembly extends to a position accessible to the front of the unit, thereby enabling maintenance operations from the front of the unit and further improving the convenience of subsequent maintenance operations for operators. In addition, by utilizing the vertically arranged connecting section, the smoothness of condensate in the water receiving tray falling into the drain pipe can be effectively improved, increasing drainage efficiency.
[0006] Furthermore, the fastening components include a fixing bracket disposed at the bottom of the water receiving tray and a fixing clamp for fixing the drain pipe to the fixing bracket. By using the fixing clamp to fix the drain section of the drain pipe to the fixing bracket at the bottom of the water receiving tray, the ease of disassembly and assembly between the drain pipe and the fixing bracket of the water receiving tray can be effectively improved. While effectively ensuring the stability of the fixed connection between the water receiving pipe and the drain pipe, the efficiency of disassembly and assembly between the drain pipe and the water receiving tray is also improved.
[0007] Furthermore, the external drainage assembly includes a bend communicating with the drain pipe and a drain hose communicating with the bend, and the connecting component connects the bend to the drain section of the drain pipe. In the embodiment provided by this utility model, by using the bend to communicate with the drain pipe, the backflow of condensate in the bend and drain hose into the heat exchanger inside the unit can be effectively prevented. Moreover, by using the drain hose, the front end of the drain hose can be effectively extended to a position accessible to the front of the unit, thereby enabling maintenance operations from the front of the unit, further improving the convenience of subsequent maintenance operations for operators, and ensuring drainage efficiency and effectiveness.
[0008] Furthermore, the bend is a U-shaped bend. Using a U-shaped bend effectively prevents condensate from flowing back into the heat exchanger within the unit, thus improving drainage efficiency, ensuring drainage performance, and enhancing safety.
[0009] Furthermore, the U-shaped bend includes a first connecting section communicating with the drainage section of the drain pipe, a second connecting section communicating with the drain hose, and a U-shaped connecting section connecting the first and second connecting sections. The height of the first connecting section is higher than the height of the second connecting section, thereby effectively ensuring the convenience of connecting the first connecting section to the drainage section of the drain pipe via a fixing clamp, while preventing condensate flowing into the drain hose through the second connecting section from flowing back into the drain pipe and heat exchanger, thus effectively improving drainage efficiency, ensuring drainage effect, and safety.
[0010] Furthermore, the connecting component comprises several first connecting clamps disposed between the first connecting section of the U-shaped bend and the drainage section of the drain pipe. By connecting the first connecting section of the U-shaped bend and the drainage section of the drain pipe with several first connecting clamps, the ease and stability of connecting the first connecting section of the U-shaped bend and the drainage section of the drain pipe by the operator after removing the maintenance plate can be effectively ensured, and leakage is prevented.
[0011] Furthermore, the second connecting section of the U-shaped bend is connected to the drain hose via a second connecting clamp. By using the second connecting clamp to connect the second connecting section of the U-shaped bend to the bend, the convenience and stability of the operator in connecting the second connecting section of the U-shaped bend to the bend can be effectively ensured, and leakage can be avoided.
[0012] Furthermore, the drain pipe is a U-shaped drain pipe, which allows the shape of the U-shaped drain pipe to be adapted to the shape of the bend pipe, and provides various embodiments of the drain pipe shape, so that users can select the appropriate drain pipe according to the actual use scenario, thereby improving the adaptability of the drainage structure of the air wall air conditioner.
[0013] The beneficial effects of the drainage structure of the wall-mounted air conditioner provided by this utility model are as follows: By detachably connecting the maintenance plate to the unit and setting the maintenance plate at the external drainage component, the operator can connect the external drainage component to the drain pipe through the connecting component after removing the maintenance plate. This effectively improves the convenience of the operator in installing the external drainage component on the drain pipe and the convenience of maintenance operations such as replacing the external drainage component later. Furthermore, by setting the front end of the drain pipe to be parallel to the bottom of the unit, after connecting the external drainage component to the drain pipe, the end of the external drainage component can extend to a position accessible to the front of the unit, thereby enabling maintenance operations from the front of the unit, further improving the convenience of later maintenance operations for the operator.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] See Figure 1-5This utility model provides a drainage structure 100 for a wall-mounted air conditioner. The drainage structure 100 is located at the bottom of the heat exchanger 201 inside the unit 200. It includes a water receiving tray 11, a drain pipe 12 connected to the water receiving tray 11, and an external drainage component 20 connected to the drain pipe 12. A maintenance plate 30 is provided inside the unit 200 at the external drainage component 20. The maintenance plate 30 is detachably connected to the unit 200. The end of the drain pipe 12 is fixed to the bottom of the water receiving tray 11 by a fastening component. The front end of the drain pipe 12 is parallel to the bottom of the unit 200. The external drainage component 20 is connected to the end of the drain pipe 12 by a connecting component. By detachably connecting the maintenance plate 30 to the unit 200 and placing the maintenance plate 30 at the external drainage component 20, operators can easily connect the external drainage component 20 to the drain pipe 12 via the connecting component after removing the maintenance plate. This effectively improves the convenience of installing the external drainage component 20 onto the drain pipe 12 and the ease of subsequent maintenance operations such as replacing the external drainage component 20, while also preventing leaks. Furthermore, by setting the front end of the drain pipe 12 parallel to the bottom of the unit 200, the end of the external drainage component 20 can extend to a position accessible from the front of the unit 200 after connecting it to the drain pipe 12, enabling maintenance operations from the front of the unit 200 and further improving the convenience of subsequent maintenance operations for operators.
[0027] like Figure 1 and Figure 2 As shown, the drain pipe 12 is an L-shaped drain pipe, including a vertically arranged connecting section 121 that communicates with the water receiving tray 11 and a drain section 122 that communicates with the external drain assembly 20. Fastening components are disposed on the drain section 122. In the embodiment provided by this utility model, the drain section 122 is parallel to the bottom of the unit 200, so that after the external drain assembly 20 is connected to the drain section 122 of the drain pipe 12 through the connecting component, the end of the external drain assembly 20 extends to a position accessible to the front end of the unit 200, thereby enabling maintenance operations from the front of the unit 200 and further improving the convenience of subsequent maintenance operations for operators. Furthermore, by utilizing the vertically arranged connecting section 121, the smoothness of condensate water in the water receiving tray 11 flowing into the drain pipe 12 can be effectively improved, increasing drainage efficiency.
[0028] like Figure 2As shown, the fastening components include a fixed bracket 13 disposed at the bottom of the water receiving tray 11 and a fixing clamp 14 for fixing the drain pipe 12 to the fixed bracket 13. By using the fixing clamp 14 to fix the drain section 122 of the drain pipe 12 to the fixed bracket 13 at the bottom of the water receiving tray 11, the ease of disassembly and assembly between the drain pipe 12 and the fixed bracket 13 of the water receiving tray 11 can be effectively improved. While effectively ensuring the stability of the fixed connection between the water receiving tray 11 and the drain pipe 12, the efficiency of disassembly and assembly between the drain pipe 12 and the water receiving tray 11 is also improved.
[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the external drainage assembly 20 includes a bend 21 connected to the drain pipe 12 and a drain hose 22 connected to the bend 21. A connecting component connects the bend 21 to the drain section 122 of the drain pipe 12. In the embodiment provided by this utility model, by using the bend 21 to connect to the drain pipe 12, the backflow of condensate in the bend 21 and the drain hose 22 to the heat exchanger 201 in the unit 200 can be effectively prevented. Furthermore, by using the drain hose 22, the front end of the drain hose 22 can be effectively extended to a position accessible to the front of the unit 200, thereby enabling maintenance operations from the front of the unit 200, further improving the convenience of subsequent maintenance operations for operators, and ensuring drainage efficiency and drainage effect.
[0030] like Figure 4 and Figure 5 As shown, bend 21 is a U-shaped bend. By using a U-shaped bend, the condensate in bend 21 and drain hose 22 can be effectively prevented from flowing back to the heat exchanger 201 in unit 200, thereby effectively improving drainage efficiency, ensuring drainage effect and safety.
[0031] like Figure 5 As shown, the U-shaped bend includes a first connecting section 211 communicating with the drainage section 122 of the drain pipe 12, a second connecting section 213 communicating with the drain hose 22, and a U-shaped connecting section 212 connecting the first connecting section 211 and the second connecting section 213. The height of the first connecting section 211 is higher than the height of the second connecting section 213, thereby effectively ensuring the convenience of connecting the first connecting section 211 to the drainage section 122 of the drain pipe 12 via the fixing clamp 14, while preventing condensate flowing into the drain hose 22 through the second connecting section 213 from flowing back into the drain pipe 12 and the heat exchanger 201, thereby effectively improving drainage efficiency, ensuring drainage effect and safety.
[0032] like Figure 5As shown, the connecting components consist of several first connecting clamps 40 disposed between the first connecting section 211 of the U-shaped bend and the drainage section 122 of the drain pipe 12. By connecting the first connecting section 211 of the U-shaped bend and the drainage section 122 of the drain pipe 12 through several first connecting clamps 40, the ease and stability of connecting the first connecting section 211 of the U-shaped bend and the drainage section 122 of the drain pipe 12 by the operator after removing the maintenance plate 30 can be effectively ensured, and leakage is avoided.
[0033] like Figure 5 As shown, the second connecting section 213 of the U-shaped bend is connected to the drain hose 22 via the second connecting clamp 50. By using the second connecting clamp 50 to connect the second connecting section 213 of the U-shaped bend to the bend 21, the convenience and stability of the connection between the second connecting section 213 of the U-shaped bend and the bend 21 by the operator can be effectively ensured, and leakage can be avoided.
[0034] Furthermore, in other embodiments provided by this utility model, the drain pipe 12 is a U-shaped drain pipe adapted to the shape of the bend 21, thereby providing various embodiments regarding the shape of the drain pipe 12, so that users can select the appropriate drain pipe 12 according to the actual usage scenario, thereby improving the adaptability of the drainage structure 100 of the air-wall air conditioner.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
