The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the embodiments described below are some, but not all embodiments of the present invention.

Referring to fig. 1 to 6, an air outlet mesh enclosure 100 according to an embodiment of the present invention is described, which is suitable for an outdoor unit of an air conditioner.

Referring to fig. 1, an embodiment of the air outlet mesh enclosure 100 includes a frame 130 and a grille 110, where the grille 110 includes a plurality of bars 120 arranged at intervals, and the plurality of bars 120 are obliquely connected to an inner side of the frame 130 to form the grille 110. The grid bars 120 are long-strip-shaped, two ends of each grid bar 120 are respectively connected to the frame 130, and the grid bars 120 are arranged at equal intervals, so that a gap 111 for air outlet is formed between the adjacent grid bars 120.

Referring to fig. 1 and 2, the frame 130 includes a top edge, a bottom edge, a left side edge and a right side edge, the top edge, the left side edge, the bottom edge and the right side edge are sequentially connected to form the square frame 130, the grid bars 120 are parallel to each other and arranged in an inclined manner, fig. 1 shows a front view of the grid 110, when the air-out device is used, the air is discharged from inside to outside, the grid bars 120 have an air guiding function, and meanwhile, as the grid bars 120 are in an inclined state, when rainwater falls onto the grid 110, the rainwater can be rapidly discharged downwards along the inclined direction of the grid bars 120 under the action of gravity, so that the rainwater is prevented from accumulating on the grid 110, and a. It is understood that the inclination direction of the grill 120 is not limited to the inclination direction of the embodiment shown in fig. 1, and for example, the grill 120 may be inclined downward from left to right. In addition, the shape of the frame 130 is not limited to a square shape, and may be a circle, an ellipse, or the like.

Fig. 3 is a cross-sectional view perpendicular to the direction of the grid bars 120, wherein the rear side of the grid bars 110 is an air inlet side, the front side thereof is an air outlet side, the direction indicated by the arrow in fig. 3 is an air outlet direction, the airflow flows toward the grid bars 110 along the arrow direction and flows out along the gaps 111 between the adjacent grid bars 110, and the grid bars 120 guide the air outlet.

Referring to fig. 4 and 5, the upper side of the grill 120 has a first inclined surface 121 and a second inclined surface 122, the first inclined surface 121 is inclined downward toward the air inlet side, the second inclined surface 122 is inclined downward toward the air outlet side, and the width of the second inclined surface 122 is greater than the width of the first inclined surface 121. Meanwhile, the lower side of the grill 120 has a third inclined surface 123 and a fourth inclined surface 124, the third inclined surface 123 is inclined upward toward the air inlet side, the fourth inclined surface 124 is inclined upward toward the air outlet side, and the width of the third inclined surface 123 is greater than that of the fourth inclined surface 124. In the embodiment, the widths of the first inclined surface 121, the second inclined surface 122, the third inclined surface 123 and the fourth inclined surface 124 may be understood as the length of the grill 110 in the width direction, i.e., the front-rear direction as shown in fig. 5, and then the length of the second inclined surface 122 is greater than the length of the first inclined surface 121 and the length of the third inclined surface 123 is greater than the length of the fourth inclined surface 124 in the front-rear direction.

Referring to fig. 5, in the present embodiment, when the air outlet cover 100 discharges air, the air flow sequentially flows through the first inclined surface 121 and the second inclined surface 122 on the upper side of the grid 120, and the air flow sequentially flows through the third inclined surface 123 and the fourth inclined surface 124 on the lower side of the grid 120. Since the first inclined plane 121 and the third inclined plane 123 are inclined toward the air inlet side and the second inclined plane 122 and the fourth inclined plane 124 are inclined toward the air outlet side, the grid bar 120 is gradually narrowed toward both ends in the width direction, it can be understood that the joint of the first inclined plane 121 and the second inclined plane 122 is the highest point of the upper side surface of the grid bar 120, and the joint of the third inclined plane 123 and the fourth inclined plane 124 is the lowest point of the lower side surface of the grid bar 120, and the cross section of the grid bar 120 shown in fig. 5 is in a shape that the middle part is thick and both ends are thin.

In the embodiment, the inclined planes in different orientations are arranged on the upper side and the lower side of the grid bars 120, so that on one hand, the wind resistance can be reduced, and the heat dissipation effect can be improved, on the other hand, because the second inclined plane 122 is longer relative to the first inclined plane 121 and the second inclined plane 122 inclines towards the air outlet side, when the grid bars work in rainy days, rainwater falling onto the grid bars 120 can flow away from the air outlet side along the second inclined plane 122, and the rainwater cannot spread to the first inclined plane 121 along the second inclined plane 122, so that the rainwater blocking effect is achieved.

Further, because the fourth inclined plane 124 is shorter than the third inclined plane 123, that is, the length of the fourth inclined plane 124 is less than the length of the second inclined plane 122, because the adjacent grid bars 120 are parallel to each other, the projection of the fourth inclined plane 124 in the vertical direction can fall on the second inclined plane 122 of the adjacent grid bar 120, and thus, the water flow drops along the fourth inclined plane 124 and can fall on the second inclined plane 122 of the adjacent grid bar 120, and can block the water flow from spreading to the third inclined plane 123 along the fourth inclined plane 124, so that the grille 110 has the function of blocking rainwater, can effectively prevent the rainwater from entering the inner side of the air outlet mesh enclosure 100, effectively improves the waterproof performance of the air outlet mesh enclosure 100, and has a practical and reliable structure.

Referring to fig. 5, it can be understood that the greater the length of the second inclined surface 122, the longer the rainwater falling on the second inclined surface 122 spreads upward along the inclined surface, which can be understood as the distance of water flow climbing, and the longer the climbing distance, the more difficult the rainwater can reach the first inclined surface 121, and the better the water retaining effect is. Similarly, the longer the third inclined plane 123 is, the longer the distance of the water flow climbing along the third inclined plane 123 is, and the better the water retaining effect is. Therefore, the upper and lower sides of the grid bars 120 can prevent water from spreading inwards, and an effective waterproof effect is achieved.

In some embodiments, the ratio of the width of the second slope 122 to the width of the first slope 121 is at least greater than 2:1, i.e., the length of the second slope 122 is at least 2 times the length of the first slope 121 in the front-to-back direction of the grille 110. It can be understood that, in the case that the width of the grid 120 is constant, the longer the second inclined surface 122, the shorter the first inclined surface 121, and the larger the inclination angle of the first inclined surface 121, the smaller the inclination angle of the second inclined surface 122, and the smaller the angle of the second inclined surface 122, the easier the water flow climbs, i.e. the water flow easily spreads from the second inclined surface 122 to the first inclined surface 121. Therefore, in this embodiment, the ratio of the width of the second inclined surface 122 to the width of the first inclined surface 121 is in the range of 2 to 5, that is, the length of the second inclined surface 122 is not greater than 5 times of the length of the first inclined surface 121, so as to avoid the situation that the inclination angle of the second inclined surface 122 is too small, and simultaneously avoid the influence on the wind guiding effect due to the increase of wind resistance caused by too large inclination angle of the first inclined surface 121.

In an embodiment, the ratio of the width of the third inclined plane 123 to the width of the fourth inclined plane 124 is at least greater than 2:1, i.e., the length of the third inclined plane 123 is at least 2 times the length of the fourth inclined plane 124 along the front-rear direction of the grille 110. It can be understood that, in the case that the width of the grills 120 is constant, the longer the third inclined plane 123 is, the shorter the fourth inclined plane 124 is, and at the same time, the smaller the inclination angle of the third inclined plane 123 is, the larger the inclination angle of the fourth inclined plane 124 is, and the smaller the angle of the third inclined plane 123 is, which makes it easier for the water to climb, i.e., the water easily spreads along the third inclined plane 123 to the inside of the grills 110. Therefore, in the present embodiment, the ratio of the width of the third inclined surface 123 to the width of the fourth inclined surface 124 is in the range of 2 to 5, that is, the length of the third inclined surface 123 is not greater than 5 times the length of the fourth inclined surface 124, so as to avoid the situation that the inclination angle of the third inclined surface 123 is too small.

Referring to fig. 1, in some embodiments, the grills 120 are parallel and arranged obliquely, the top edge of the frame 130 is used as a reference edge, the top edge is a horizontal direction, and the included angle α between the grills 120 and the top edge is the inclination angle of the grills 120, in this embodiment, the included angle α between the grills 120 and the top edge is 45 °, and when rainwater falls onto the grills 120, the rainwater can rapidly slide down along the grills 120 under the action of gravity, so as to avoid the rainwater from accumulating on the grille 110.

It will be readily appreciated that the greater the angle α between the grid 120 and the top edge, the more likely the flow will run in the downward direction, but considering that the drainage efficiency will be reduced when the angle between the grid 120 and the top edge is too small, whereas when the angle between the grid 120 and the top edge is too large, such as when the grid 120 is perpendicular or nearly perpendicular to the top edge, the falling rain can easily enter the inner side from the gaps 111 of the grid 110, losing its effect of blocking the entry of rain, and therefore, the angle α between the grid 120 and the top edge may range from 15 ° ≦ α ≦ 75 °, for example, the angle α may range from 15 °, 30 °, 60 °, and so on.

When the device is installed and used, the grid bars 120 which are obliquely arranged on the grid 110 can enable rainwater to be quickly drained downwards under the action of gravity, so that the rainwater is prevented from accumulating on the grid 110; meanwhile, rainwater on the grid bars 120 flows out along the second inclined plane 122 of the upper side to the air outlet direction, and blocks water flow from spreading to the first inclined plane 121 along the second inclined plane 122, and the water flow can drop onto the second inclined plane 122 of the adjacent grid bars 120 through the fourth inclined plane 124, and the third inclined plane 123 can block water flow from spreading to the inner side, so that the water flow cannot spread to the inner side from the upper side and the lower side of the grid bars 120, rainwater is effectively prevented from entering the inner side of the air outlet mesh enclosure 100, the waterproof performance of the air outlet mesh enclosure 100 is improved, and the structure is practical and reliable.

Referring to fig. 5, in some embodiments, the first inclined surface 121, the second inclined surface 122, the third inclined surface 123 and the fourth inclined surface 124 are all flat surfaces, and the first inclined surface 121 and the third inclined surface 123 are inclined and extend toward the air inlet side, so that the first inclined surface 121 and the third inclined surface 123 are connected at the end of the air inlet side of the grill 120; the second inclined surface 122 and the fourth inclined surface 124 are inclined and extended toward the air-out side so that the second inclined surface 122 and the fourth inclined surface 124 are connected at the end of the grill 120 on the air-out side.

The first cambered surface 125 is arranged at the end part of the air inlet side of the grid 120, the first inclined surface 121 and the third inclined surface 123 are connected through the first cambered surface 125, the second cambered surface 126 is arranged at the end part of the air outlet side of the grid 120, the second inclined surface 122 and the fourth inclined surface 124 are connected through the second cambered surface 126, namely, the first inclined surface 121 and the third inclined surface 123 are in transitional connection through the first cambered surface 125, and the second inclined surface 122 and the fourth inclined surface 124 are in transitional connection through the second cambered surface 126.
