An air outlet is provided on the side wall of the ventilation pipeline, and a wind guide plate is provided on the inner wall of the ventilation pipeline, and the wind guide plate is arranged towards the air outlet; a gap for the air flow to pass through is left between the wind guide plate and the inner wall of the ventilation pipeline. When the air flow circulates in the ventilation pipeline, the wind guide plate guides the air flow towards the air outlet direction, which helps to discharge a relatively large amount of the flowing air from the air outlet, saving energy and being efficient. A relatively large wind force can be maintained at the air outlet, thereby quickly increasing and decreasing the indoor temperature, and increasing the practicability of the ventilation pipeline; at the same time, the gap left between the wind guide plate and the inner wall of the ventilation pipeline can also enable the air flow to continue to circulate along the ventilation pipeline without affecting the air flow.

[0004] When the above device is in use, water vapor and cold energy water will be generated during the ventilation process, and it is difficult for the above ventilation pipeline to discharge the condensate in time, resulting in an increase in the weight of the pipeline and a situation of being prone to damp, corrosion, and oxidation.

The two ventilation drainage pipes are connected by a section of folding elbow, and a drainage pipe is fixedly installed at the center of the bottom end of the folding elbow.

[0008] As a further solution of the present utility model, mounting holes are respectively provided on the top fixing plate and the telescopic plate.

[0029] Please refer to the attached Figure 1 specification. A ventilation and drainage assembly for a heating, ventilation and air conditioning (HVAC) device according to an embodiment of the present utility model includes a top fixing plate 1. A pair of telescopic plates 2 are slidably installed inside the top fixing plate 1. At the bottom of the exposed part of each telescopic plate 2, a telescopic adjustment member 3, a rotational connection assembly 4 and a ventilation drain pipe 5 are sequentially connected. The telescopic adjustment member 3 is linked with the rotational connection assembly 4 to adjust the inclination angle of the ventilation drain pipe 5. Then, a folding elbow 6 is used to connect a pair of ventilation drain pipes 5. A drain pipe 7 is fixedly installed at the center of the bottom end of the folding elbow 6 for discharging condensed water. As Figure 6 shown, the folding elbow 6 facilitates the collection of condensed water and makes the condensed water gather in the middle. The liquid enters the drain pipe 7 and is discharged to the outside through a hose installed outside the drain pipe 7 or into a rainwater pipe. Preferably, an anti-odor blocking member 8 can also be installed at the bottom end of the drain pipe 7. The anti-odor blocking member 8 can prevent the rainwater pipe from smelling through the drain pipe 7 into the ventilation drain pipe 5.

[0030] During use, stretch and adjust the top fixing plate 1 and the telescopic plate 2 to adjust the top plate structure to the required length, and use fixing parts such as bolts to fix the top plate structure on the ceiling. Adjust the telescopic adjusting part 3 and the rotating connection assembly 4 so that the ventilation drain pipe 5 reaches the required inclination angle. Thus, the installation is completed. Condensate will flow through the ventilation drain pipe 5 and be collected by the folding elbow 6, and finally gather in the middle and enter the drain pipe 7. Then, a hose is installed outside the drain pipe 7 and discharged outdoors or into the rainwater pipe, and the ventilation and drainage of the HVAC equipment can be completed.

[0031] As a further solution of the present utility model, as Figure 2 shown, the telescopic adjusting part 3 includes a lead screw sleeve 31 and a lead screw 32. The lead screw sleeve 31 is rotatably connected to the telescopic plate 2, the lead screw 32 is helically connected to the lead screw sleeve 31, and an anti-slip strip is fixedly connected to the outside of the lead screw sleeve 31. Rotate the lead screw sleeve 31 to make the lead screw 32 rotate and lift in the lead screw sleeve 31. The telescopic adjusting part 3 can adjust the overall length, and then drive the ventilation drain pipe 5 to tilt, so that the liquid can smoothly enter the folding elbow 6. Further, as Figure 3 shown, while the telescopic adjusting part 3 drives the ventilation drain pipe 5 to adjust the inclination angle, the rotating connection assembly 4 is cooperated to facilitate linkage. In this embodiment, the rotating connection assembly 4 includes an upper fixing part 41 and a rotating block 42. The upper fixing part 41 is fixedly connected to the telescopic adjusting part 3, the rotating block 42 is fixedly connected to the ventilation drain pipe 5, the upper fixing part 41 is rotatably connected to the rotating block 42, and the rotating block 42 is arranged symmetrically left and right.

[0032] As a further solution of the present utility model, mounting holes are provided on both the top fixing plate 1 and the telescopic plate 2. The mounting holes of the top fixing plate 1 are arranged at the four corner positions. The top fixing plate 1 and the telescopic plate 2 can be fixed on the ceiling through the mounting holes.

[0033] As Figure 4 、 5 shown, as a further solution of the present utility model, the odor-proof blocking part 8 includes a cover 81 and a torsion spring 82. The torsion spring 82 is installed outside the rotating shaft of the cover 81. One end of the torsion spring 82 is fixedly connected to the cover 81 and the other end is fixedly connected to the drain pipe 7 to realize the rotating connection between the odor-proof blocking part 8 and the drain pipe 7. During implementation, under the action of the torsion spring 82, the cover 81 can keep blocking when the drain pipe 7 is empty to avoid odor cross-talk.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0035] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
