DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Reference Figures 1-2This utility model provides an embodiment of a ventilation and drainage device for HVAC equipment, comprising a HVAC duct 1 for connecting and installing the HVAC equipment within a building, an air intake grille 2 for providing air intake to the HVAC equipment fixedly connected to one end of the HVAC duct 1, a drainage trough 3 with a funnel-shaped water guide structure fixedly connected to the bottom end of the HVAC duct 1, and the top of the drainage trough 3 being connected through to the inner bottom end of the HVAC duct 1, a drain pipe 4 fixedly connected to the bottom end of the drainage trough 3 near the air intake grille 2, a drainage filter 5 fixedly connected to the top of the drainage trough 3 for draining water and intercepting the return of clean dust discharged by the dust removal component 9, and water guide seats 6 with a sloping water guide structure fixedly connected to both sides of the bottom of the inner wall of the HVAC duct 1. Through the water guide seats 6 combined with the drainage trough 3, the condensate generated by the HVAC duct 1 during heating or cooling can be collected centrally, and the condensate and dust collected by the dust removal component 9 can be collected by the drain pipe 4 and discharged as a clean flushing solution for use.

[0030] Reference Figures 1-4 Inside the heating ventilation duct 1, near the lower edge of the side close to the air intake grille 2, a slide rail 7 is fixedly connected to an internally slidably mounted electric pulley 8. A dust removal assembly 9 for cleaning the air intake grille 2 is installed on the top of the electric pulley 8. The dust removal assembly 9 includes a dust collection hood 91 with a motor 10 fixedly connected to its top. A cleaning roller brush 11 is rotatably connected inside the dust collection hood 91. The top of the cleaning roller brush 11 is fixedly connected to the bottom output end of the motor 10, and a bearing seat is fixedly connected between the bottom end of the cleaning roller brush 11 and the bottom end of the inner wall of the dust collection hood 91. The electric pulley 8 drives the cleaning roller brush 11 inside the dust collection hood 91, which is then driven by the motor 10, allowing it to clean along the slide rail 7. The dust collection grille 2 is used for dust collection and centralized dust collection. A dust collection fan 92 is fixedly connected to the back of the dust collection hood 91 to provide dust collection power. Three dust collection pipes 93 for multi-point high-efficiency dust collection are connected through one end of the dust collection fan 92 and the inside of the dust collection hood 91. The three dust collection pipes 93 are fixedly connected to the suction end of the dust collection fan 92 through a connecting pipe. A dust discharge pipe 94 with a retractable flexible hose is connected through the other end of the dust collection fan 92 and the drain filter 5 to collect and discharge dust. The bottom end of the dust discharge pipe 94 is set at the top center of the drain pipe 4, so as to facilitate the directional, centralized and rapid discharge of cleaning dust.

[0031] Working principle: When the HVAC equipment provides air intake dust removal, the cleaning roller brush 11, driven by the motor 10, is rotated inside the dust collection hood 91 by starting the electric pulley 8. It can move left and right along the slide rail 7 to clean the air intake grille 2 of the HVAC duct 1. During the cleaning process, the dust collection fan 92 is started to provide dust collection power. The dust collection is concentrated by the dust collection hood 91 connected to the outer periphery of the cleaning roller brush 11 by the dust collection pipe 93. The dust is collected and discharged through the corresponding drain pipe 4 and the drain filter 5. The drain filter 5 intercepts the clean dust discharged by the dust collection component 9 and returns it without affecting the drainage. At the same time, the condensate generated by the HVAC duct 1 during heating or cooling is collected and discharged by the drain trough 3. The condensate can flow to the drain pipe 4 in sequence to flush and remove dust and discharge it in a centralized manner.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
