As shown in fig. 1 to 4, the present disclosure provides a rain-proof joint 100 for setting up in the air intake department of a new wind pipe 200 of an air conditioner, specifically, the rain-proof joint 100 includes a sleeve 1 and a grille 2, wherein, an opening for fresh air to enter is provided on the side wall of the sleeve 1, and in use, the opening faces downward so as to avoid rainwater from directly dripping into the sleeve 1 and entering the new wind pipe 200 through the sleeve 1. Wherein, the grille 2 is covered at the opening and forms a first fresh air channel 11 extending along the axial direction with the inner wall of the sleeve 1, and the grille 2 has the function of preliminary filtration, and is mainly used for filtering larger particles such as mosquitoes or flying cotton wool, and the like, so as to prevent the larger particles from blocking the rainproof joint 100 after entering the sleeve 1.

The grille 2 comprises a lateral grille 21 for the lateral entry of fresh air into the first fresh air duct 11 from the casing 1 and an axial grille 22 for the axial entry of fresh air into the first fresh air duct 11 from the casing 1. The lateral direction herein refers to the lateral direction of the vessel wall. In detail, as shown by solid arrows in fig. 1, a part of fresh air enters the first fresh air channel 11 through the lateral grille 21, and then enters the fresh air duct 200 in the axial direction under the guidance of the first fresh air channel 11 extending in the axial direction, and the part of fresh air inevitably directly impacts the inner wall of the sleeve 1 due to a large flow velocity, so that wind loss is generated. As shown by the dotted arrow in fig. 1, another part of fresh air can enter the first fresh air channel 11 through the axial grille 22, and the other part of fresh air directly enters the first fresh air channel 11 along the axial direction, so that the problem that the fresh air impacts the inner wall of the sleeve 1 like lateral air inlet is not easy to occur, thereby reducing the air loss and being beneficial to improving the air inlet quantity. In summary, by making fresh air enter the first fresh air channel 11 from the lateral direction and the axial direction respectively, not only sufficient intake air quantity can be ensured, but also wind loss can be reduced.

The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects: the rain-proof joint 100 that this disclosure provided sets up grid 2 in the opening part that supplies new trend to get into, and grid 2 includes the side direction grid 21 that supplies new trend from the side direction to get into first new wind passageway 11 and supplies new trend to get into first new wind passageway 11 from the axial grid 22 of axial, that is, at least some new wind can get into first new wind passageway 11 along the axial, compare with the scheme that the correlation technique made the new trend all get into from the side direction, this disclosure makes at least some new wind can get into from the axial, the impact with sleeve pipe 1 inner wall in first new wind passageway 11 has been reduced, thereby play the effect that reduces wind loss, and then air inlet efficiency is improved.

In some embodiments, as shown in fig. 1 and 2, the first end of the sleeve 1 is provided with a rain shield 13, and the axial grille 22 is spaced from the rain shield 13 to form a second fresh air channel 12, the second fresh air channel 12 being in axial communication with the first fresh air channel 11. Referring also to the air conditioner of fig. 5, in assembled relationship, the first end of the sleeve 1 is the end of the sleeve 1 remote from the fresh air duct 200. The rain shield 13 may be, for example, a flap or baffle integrally formed at the first end of the sleeve 1 to prevent rain water from entering the first fresh air channel 11 directly from the axial direction.

The axial grille 22 is spaced from the rain shield 13 to form a second fresh air channel 12, i.e., as indicated by the dashed arrow in fig. 1, a negative pressure is formed in the second fresh air channel 12, and fresh air first enters the second fresh air channel 12 from the side direction and then continues to enter the first fresh air channel 11 in the axial direction. Considering that the pressure difference of the part of fresh air entering the first fresh air channel 11 after passing through the second fresh air channel 12 is greatly reduced, so that little or no acceleration to the fresh air is generated, which is beneficial to further avoiding the impact of the fresh air entering the first fresh air channel 11 on the inner wall of the sleeve 1.

Further, referring also to fig. 3, the linear distance L1 of the rain shield 13 to the axial grill 22 is 25% -70% of the linear distance L of the rain shield 13 to the outlet of the first fresh air duct 11. For example, the linear distance L1 of the rain shield 13 to the axial grill 22 is selected in the range of 50 mm to 90 mm, and the linear distance L of the rain shield 13 to the outlet of the first fresh air duct 11 is in the range of 80 mm to 140 mm. By configuring the range of the linear distance L1 from the rain shielding portion 13 to the axial grille 22 to occupy the linear distance L from the rain shielding portion 13 to the outlet of the first fresh air duct 11, it is achieved to reasonably adjust the amount of air entering the first fresh air duct 11 from the side and the amount of air entering the first fresh air duct 11 from the axial direction while minimizing the impact of the axial air intake on the inner side wall of the sleeve 1.

Referring to fig. 1, 2 and 4 together, the lateral grid 21 includes a plurality of transverse ribs 211 and a plurality of longitudinal ribs 212 arranged in a staggered manner. The connection parts of the two ends of the plurality of transverse ribs 211 and the sleeve 1 are provided with stop structures 23 for stopping rainwater from flowing along the transverse ribs 211 to the inner wall of the sleeve 1. Specifically, in the related art in which the stopper structure 23 is not provided, that is, the connection between the lateral rib 211 and the inner wall of the duct 1 is approximately smooth, at this time, under a large pressure difference, upward resultant force against gravity is formed to the raindrops, thereby causing rainwater to easily enter the inner wall of the duct 1 and thus the inside of the air conditioner through the fresh air duct 200.

The present disclosure is to provide the stopper structure 23 at the junction of the two ends of the transverse rib 211 and the sleeve 1, specifically, to form a break difference between the transverse rib 211 and the sleeve 1, that is, to make a discontinuous connection between the transverse rib 211 and the inner wall of the sleeve 1. The pressure difference is reduced by the presence of the stop structure 23, so that the resultant force on the formation of the raindrops is insufficient to overcome the force of gravity, so that when the raindrops flow along the transverse ribs 211 to the stop structure 23, they will drop under the force of gravity and will not enter the sleeve 1. In some embodiments, the stopping structure 23 is configured to be stepped, and it should be understood that other shapes or structures that can achieve the purpose of making the resultant force of the formation of the raindrops insufficient to overcome the gravity force, and thus stopping the flow of the rainwater along the transverse ribs 211 toward the inner wall of the sleeve 1 can be applied in the present disclosure, and will not be described herein.

The lateral grid 21 is described above as including a plurality of transverse ribs 211 and longitudinal ribs 212, it being understood that the axial grid 22 may be provided with a plurality of transverse ribs and longitudinal ribs simultaneously. In some embodiments, the grid 2 may be configured to be an integral structure with the sleeve 1, for example, the sleeve 1 and the grid 2 are integrally formed by injection molding, and the integral structure enables the sleeve 1 and the grid 2 to have better connection strength, avoids falling off to affect use, and is also beneficial to reducing the number of parts to be installed and improving the assembly efficiency.

As shown in fig. 3, the distance D between the plurality of lateral ribs 211 and between the plurality of longitudinal ribs 212, or between the plurality of lateral ribs 211, or between the plurality of longitudinal ribs 212 is in the range of 5 mm to 16 mm. By reasonably setting the intervals between the transverse ribs 211 and/or the longitudinal ribs 212, larger particles can be prevented from entering the sleeve 1 easily due to the too large intervals, and the reduction of the air inlet caused by the too small intervals can be avoided.

As shown in fig. 1 and 2, the second end of the casing 1 is provided with a fitting portion 14 for detachable connection with the fresh air duct 200. The mating portion 14 may be configured as a connection tube integrally formed with the sleeve 1. The fit portion 14 and the new air pipe 200 can be connected in an interference fit manner, so that the installation is convenient. The engaging portion 14 may further be provided with a guiding portion, such as a guiding slope, so that the engaging portion is more easily inserted into the fresh air duct 200, thereby improving the installation efficiency between the rainproof joint 100 and the fresh air duct 200. In addition, a sealing ring can be further arranged on the matching part 14, so that the sealing performance between the rainproof joint 100 and the fresh air pipe 200 is improved. It should be noted that other removable connection methods, such as bolting or clamping, can be applied to the present disclosure to achieve the removable connection of the mating portion 14 and the fresh air duct 200.

According to a second aspect of the embodiments of the present disclosure, as shown in fig. 5, there is also provided an air conditioner including a blower 300, a fresh air duct 200, and a rainproof joint 100 of any one of the above, the rainproof joint 100 being connected to the fresh air duct 200. The fan 300 is used for generating negative pressure in the sleeve 1 and sucking external fresh air. At least the opening of the flashing 100 is exposed to the building after installation. The rain joint 100 and the fresh air pipe 200 can be detachably connected through the matching part 14 connected through interference fit, so as to be convenient for maintenance.
