Referring to fig. 1 to 4, an embodiment of the present application provides a fresh air assembly 100, including: an air inlet box 200, a fresh air pipe 400 and a water outlet pipe 300; the air inlet box 200 comprises a box body 210 and an air inlet pipe 220, two ends of the air inlet pipe 220 are respectively communicated with the box body 210 and the fresh air pipe 400, the air inlet pipe 220 is provided with a water collecting tank 221, and the bottom of the water collecting tank 221 is provided with a water outlet 222; the drain pipe 300 is connected with the drain port 222, and an included angle between the extending direction of the drain pipe 300 and the airflow direction in the fresh air pipe 400 is A, wherein A satisfies: a is more than 90 degrees and less than or equal to 180 degrees.

It should be noted that the fresh air component 100 provided in the embodiment of the present application is suitable for a fresh air machine or a fresh air conditioner; the fresh air conditioner can be a wall-mounted fresh air conditioner or a cabinet fresh air conditioner. An air inlet cavity 213 is formed inside the box body 210 of the air inlet box 200, and a fan (not shown) such as a centrifugal fan is installed inside the air inlet cavity 213; and the box body 210 is also provided with an air outlet pipe 230, the air outlet pipe 230 extends to the indoor side, and the air inlet pipe 220 and the air outlet pipe 230 are both communicated with the box body 210 and extend into the air inlet cavity 213. The fresh air duct 400 extends to the outdoor side, and when the blower is started, the blower drives the airflow to be discharged from the air inlet cavity 213 to the indoor side through the air outlet duct 230; meanwhile, the inside of the air inlet chamber 213 is at a negative pressure, and outdoor air is sucked into the cabinet 210 through the fresh air duct 400 and the air inlet duct 220. In addition, the airflow direction within the fresh air duct 400 is generally parallel to the central axis of the fresh air duct 400.

It should be noted that, in the prior art, in order to prevent outdoor rainwater from entering the box 210, a water blocking mechanism (not shown) and/or a water collecting mechanism (not shown) is mostly arranged at the air inlet 410 of the fresh air duct 400, but some fine raindrops mixed in the air still flow into the fresh air duct 400 along with the fresh air, and the drainage effect is not ideal. In addition, because the water outlet 222 is communicated with the external space, when the fast flowing fresh air flows through the water outlet 222, part of the fresh air flows out from the water outlet 222 to the outdoor side along the flowing direction, and the fresh air volume of the fresh air assembly 100 is reduced.

By arranging the water collection tank 221 on the air inlet pipe 220, the water collection tank 221 is far away from the air inlet 410 of the fresh air pipe 400; when raining outside the room, part of the rain water is sucked into the fresh air duct 400 along with the air, and in the process of passing through the fresh air duct 400 and the air inlet duct 220, most of the rain water gradually drops on the side wall of the pipeline under the action of gravity and flows into the water collection tank 221 along the fresh air duct 400 and the air inlet duct 220. Wherein, the water outlet 222 of the water collecting tank 221 is communicated with the water outlet pipe 300, and the rainwater collected in the water collecting tank 221 will flow along the water outlet pipe 300 and be discharged to the outdoor side; in addition, because the included angle between the extending direction of the drain pipe 300 and the airflow direction in the fresh air pipe 400 is A, the angle of A is larger than 90 degrees and not larger than 180 degrees, namely, the flowing direction of the water in the drain pipe 300 is opposite to the flowing direction of the fresh air, the drain pipe 300 has a certain blocking effect on the fresh air flowing through the vicinity of the water collecting tank 221, the fresh air can be effectively prevented from entering the drain pipe 300 and flowing out to the outdoor side, and the air intake of the fresh air component 100 is ensured.

Referring to fig. 2, in the vertical direction, after entering the fresh air duct 400, the rainwater gradually drops to the bottom of the air inlet duct 220 under the action of its own gravity and flows toward the water collecting tank 221 under the action of the airflow; due to the height difference between the bottom of the water collection tank 221 and the bottom of the air inlet pipe 220, the rainwater will continue to drip and collect in the water collection tank 221, and finally flow out through the water discharge pipe 300 connected to the water discharge port 222. It can be understood that a water collecting tank 221 for further dripping and collecting rainwater is provided between the air inlet pipe 220 and the water outlet pipe 300, that is, the air inlet pipe 220 and the water outlet pipe 300 have a height difference in the vertical direction, which can provide enough space for the arrangement of the air inlet pipe 220 and the water outlet pipe 300.

Preferably, the height of the end of the drain pipe 300 away from the drain port 222 is not higher than the height of the drain port 222 in the vertical direction. Therefore, the rainwater can be smoothly discharged under the action of the gravity of the rainwater.

Preferably, the water collection tank 221 is disposed in the air inlet chamber 213, i.e., at the end of the air inlet duct 220 remote from the fresh air duct 400.

The water collecting tank 221 is arranged far away from the air inlet 410, so that the falling distance of rainwater in fresh air in the fresh air pipe 400 and the air inlet pipe 220 can be prolonged; guaranteed that most rainwater all can be dropped under self action of gravity to flow to the water catch bowl 221 in, reduced the rainwater volume that enters into air inlet chamber 213 or indoor side, improved the operational reliability and the user experience of new trend subassembly 100.

Specifically, the air inlet duct 220 extends away from the air inlet chamber 213, i.e., the air inlet duct 220 extends outside the cabinet 210. The body of the air inlet pipe 220 is reserved outside the box body 210 to connect the fresh air pipe 400, so that the installation of a user is facilitated.

Specifically, the cabinet 210 includes a front case 211 and a rear case 212, the front case 211 and the rear case 212 enclose an air inlet chamber 213, and the air inlet duct 220 and the water outlet duct 300 are disposed on the front case 211. Alternatively, the air inlet duct 220 may be integrally provided with the cabinet 210.

Optionally, two air outlet pipes 230 are arranged on the box body 210, and the extending directions of the two air outlet pipes 230 are opposite, so that fresh air can be provided for two indoor different directions.

In some embodiments, a =180 °.

Through setting up the extending direction with drain pipe 300 to be opposite with the new trend flow direction, the contained angle between the two is 180, drain pipe 300 can the maximize block new trend and flow into to guarantee that only rainwater flows through drain pipe 300, improve new trend subassembly 100's intake.

In some embodiments, the fresh air component 100 includes a water return pipe 310 (not shown), the water return pipe 310 is installed at an end of the water discharge pipe 300 far from the water discharge port 222, the water return pipe 310 communicates with the water discharge pipe 300, and the water return pipe 310 is a U-shaped pipe.

It should be noted that when the outdoor air speed is fast and the wind direction of part of the outdoor air is opposite to the extending direction of the drain pipe 300, the outdoor air may blow the rainwater in the drain pipe 300 to reversely flow to the air inlet chamber 213, and dangerous situations such as a short circuit of the fan are easily caused.

By installing the U-shaped water return pipe 310 on the water discharge pipe 300, on one hand, outdoor air can be prevented from reversely blowing into the air cavity 213 along the water discharge pipe 300, and the safety of the fresh air component 100 is improved; on the other hand, the rainwater entering the water return pipe 310 can be temporarily retained at the bottom of the U-shaped pipe to form a water seal, and the pipelines on the two sides of the water return pipe 310 can be blocked, that is, only the rainwater can enter the water return pipe 310, so that the air intake of the fresh air component 100 is increased, mosquitoes and other insects outside the room are prevented from entering the box body 210 through the drain pipe 300, and the reliability of the fresh air component 100 is improved.

Specifically, in the vertical direction, the height of the end of the U-shaped pipe away from the drain pipe 300 is lower than the height of the drain port 222, that is, the inlet of the drain pipe 300 is higher than the outlet, and the return pipe 310 can smoothly drain rainwater.

Further, in other embodiments, the water return pipe 310 may also be an S-shaped pipe, a W-shaped pipe, or the like, which is not limited herein.

In some embodiments, a check valve (not shown) is provided in the drain 300.

By installing the check valve in the drain pipe 300, rainwater in the drain pipe 300 can be ensured to flow in one direction, and the air intake of the fresh air component 100 is increased; mosquitoes and other insects outside the room can be prevented from entering the box body 210 through the drain pipe 300, and the reliability of the fresh air assembly 100 is improved.

In some embodiments, water collection groove 221 is an arcuate groove having a central angle of 180 °.

It will be appreciated that the air inlet duct 220 is a circular tube.

By arranging the water collecting tank 221 as an arc-shaped groove matched with the air inlet pipe 220, the height of rainwater at different positions on the pipeline of the air inlet pipe 220 dropping into the water collecting tank 221 can be reduced, small water drops caused by the rainwater dropping too high are avoided, and the rainwater in the water collecting tank 221 is prevented from overflowing.

And the central angle of the arc-shaped groove is set to be 180 degrees, namely the water collecting groove 221 is semicircular and can cover the whole diameter of the air inlet pipe 220, so that the water collecting effect of the water collecting groove 221 is ensured,

further, in other embodiments, the central angle of the water collection groove 221 may be selected according to the user's needs, such as 150 °, 210 °, or the like, without being limited thereto.

In some embodiments, grills (not shown) are provided in the air inlet duct 220 and/or the fresh air duct 400.

The grille can prevent mosquitoes, leaves and other foreign matters from entering the fresh air pipe 400; the grid can also block passing rainwater, and the blocked rainwater can slide down along the grid bars of the grid and continuously flow to the water collecting tank 221 along the pipeline, so that the water collecting amount of the water collecting tank 221 is increased.

Preferably, grills are provided in both the air inlet duct 220 and the fresh air duct 400. The grids in the fresh air duct 400 are arranged at the air inlet 410, and gaps among the grids are large, so that foreign matters with large volume can be well blocked; the grids in the air inlet pipe 220 are arranged close to the water collecting tank 221, the grids are thin, the space between the grids is small, and rainwater can be well blocked.

In some embodiments, the fresh air duct 400 is a corrugated tube, and the fresh air duct 400 is sleeved with a protection tube 600

It should be noted that, due to the limitation of the opening position on the indoor wall of the user and the installation position of the fresh air module 100, the fresh air duct 400 of the fresh air module 100 is usually required to be bent. Therefore, the fresh air duct 400 can be a corrugated pipe, which can be twisted and installed as required. However, in order to ensure that the bending angle of the corrugated pipe is large enough, the wall thickness of the corrugated pipe is thin, and the fresh air pipe 400 extends to the outdoor space, so that the corrugated pipe is easy to age due to long-term sunlight irradiation.

Through establish one deck protection tube 600 at the new tuber pipe 400 outside cover, can be in order to satisfy new tuber pipe 400 needs nimble pivoted installation needs, can also prolong new tuber pipe 400's life.

In some embodiments, the end of the fresh air duct 400 remote from the air inlet duct 220 is provided with a hood 500.

Through installing the hood 500 at the air intake 410, the upper side wall of the hood 500 blocks rainwater from dropping into the fresh air duct 400, so that outdoor air can only enter the fresh air duct 400 along the lower part, and further the probability of rainwater entering the fresh air duct 400 is reduced.

The embodiment of the present application further provides an air conditioner, the air conditioner includes the fresh air component 100 and an indoor unit (not shown in the figure) as above, and the fresh air component 100 is installed on one side of the indoor unit.
