DETAILED DESCRIPTION The embodiments of this utility model are described in detail below, and the examples are shown in the accompanying drawing. The embodiments described below with reference to the accompanying drawing are illustrative and intended only to explain this utility model; they should not be interpreted as a limitation of this utility model. The air conditioning equipment according to an example embodiment of the present utility model is described below with reference to Figure 1. The air conditioning unit according to an example embodiment of the present utility model comprises a base 1, a central frame 2 and a water collection tray 3. The base 1 and the central frame 2 are connected to each other, the base 1 and the central frame 2 enclose and form an air supply channel 11, the water collection tray 3 is provided in the air supply channel 11.The water collection tray 3 and the central frame 2 respectively have a first surface 31 and a second surface 21, which are positioned facing each other in the width direction of the water collection tray 3 (the front-back direction in Figure 1), each part of the first surface 31 forming an angle with the vertical surface, the distance a being minimum between the first surface 31 and the second surface 21 in the width direction of the water collection tray 3, the part of the first surface 31 that forms the largest angle with the horizontal plane forming an angle b with the second surface 21, the part of the first surface 31 that forms the largest angle with the horizontal plane forming an angle c with the vertical surface, such that 25 mm a 75 mm and / or 5° b 45° and / or 10° c 60°. In the air conditioning equipment of the exemplary embodiments of this utility model, it is provided that the minimum distance between the first surface 31 and the second surface 21 in the front-to-back direction is between 25 mm and 75 mm, wherein the portion of the first surface 31 that forms the largest angle with the horizontal plane is such that it forms an angle with the second surface 21 between 5° and 45°, wherein the portion of the first surface 31 that forms the largest angle with the horizontal plane is such that it forms an angle with the vertical plane between 10° and 60°, wherein each of the aforementioned values can effectively ensure that on the front side of the water collection tray 3 there is sufficient air supply space, which ensures that the airflow on the front side of the water collection tray 3 circulates smoothly, with less air suction resistance.greater air intake volume and greater air supply efficiency. It should be noted that the minimum distance between the first surface 31 and the second surface 21 in the front-back direction can be 25 mm, 50 mm, or 75 mm; the angle between the portion of the first surface 31 that forms the largest angle with the horizontal plane and the second surface 21 can be 5°, 25°, or 45°; and the angle between the portion of the first surface 31 that forms the largest angle with the horizontal plane and the vertical surface can be 10°, 35°, or 60°. The portion of the first surface 31 that forms the largest angle with the horizontal plane is the portion with the greatest inclination. In some examples of implementation, the following values are provided: 35 mm to 65 mm and / or 20° b 30° and / or 25° c 45°. By adjusting the minimum distance between the first surface 31 and the second surface 21 in the front-back direction from 35 mm to 65 mm, it is possible to prevent, on the one hand, the width of the air supply space on the front side of the water collection tray 3 from becoming too small and consequently increasing air resistance, and on the other hand, it is possible to prevent the width of the air supply space in front of the water collection tray 3 from becoming too large and consequently reducing the air supply space on the rear side of the water collection tray 3; consequently, a uniform airflow in the air supply spaces on the front and rear sides of the water collection tray 3 is effectively ensured. By adjusting the angle between the part of the first surface 31 that forms the largest angle with the horizontal plane and the second surface 21 by 20° to 30°, it is prevented, on the one hand, that the lower end of the front plate of the central frame 2 does not tilt too little forward, which reduces the width of the air supply space on the front side of the water collection tray 3 and, on the other hand, it prevents the lower end of the front plate of the central frame 2 from tilting too far forward, which affects the aesthetic image of the central frame 2. By adjusting the angle between the part of the first surface 31 that forms the largest angle with the horizontal plane and the vertical plane to a value between 10° and 60°, each part of the first surface 31 is an inclined surface that forms an angle with the horizontal direction and the maximum angle does not exceed 60°; consequently, it is effectively prevented that the airflow generates eddies when flowing through the first surface 31 and affects the efficiency of air supply. In some embodiments, as shown in Figure 1, the central frame 2 is provided with an air inlet hole 22 that is in communication with the air supply channel 11, the air inlet hole 22 is located below the water collection tray 3 and extends to the lower surface of the central frame 2, h being the minimum distance between the lower surface of the central frame 2 and the outer wall surface of the water collection tray 3 in the height direction of the water collection tray 3, such that 30 mm h 60 mm. This adjustment prevents, on the one hand, the water collection tray 3 from being too close to the air inlet grille in the air inlet hole 22 and increasing the air suction resistance at the air inlet grille, and on the other hand, it prevents the water collection tray 3 from being too close to the evaporator and affecting its water collection amount. In particular, the distance between the lower surface of the central frame 2 and the lowest point of the outer wall surface of the water collection tray 3 can be 30 mm, 45 mm and 60 mm. In some embodiments, it is provided that the distance between the first surface 31 and the second surface 21 in the width direction of the water collection tray 3 gradually decreases from bottom to top. Therefore, when the airflow flows through the air supply space on the front side of the water collection tray 3 upwards, it can conduct the airflow and simultaneously increase its airflow speed effectively, thereby ensuring the efficiency of the air supply. In some embodiments, as shown in Figure 1, it is provided that, on a projection surface perpendicular to the longitudinal direction of the water collection tray 3, the projected outline of the first surface 31 is a polyline segment, the polyline segment having several straight line segments that are connected from bottom to top one after the other, the uppermost straight line segment forming an angle b with the second surface 21 and an angle c with the vertical surface. This means that the angle of inclination of the first surface 31 with respect to the horizontal direction gradually increases from bottom to top, the angle between each part of the first surface 31 and the second surface 21 is greater than or equal to ab, and the angle between any part of the first surface 31 and the vertical surface is respectively greater than or equal to ac. This adjustment ensures that the airflow, when flowing through the first surface 31, has a good conduction effect and the probability of eddy formation is low, thereby simultaneously ensuring that on the front side of the water collection tray 3 there is a sufficiently wide air supply space to guarantee a uniform airflow. In particular, the polyline segment also comprises an arc segment, and any two adjacent straight polyline segments are smoothly connected to each other by an arc segment. In some embodiments, it is provided that three straight line segments are present and that the lowest straight line segment forms an angle with the width direction of the water collection tray 3, the middle straight line segment forming an angle β with the width direction of the water collection tray 3 and the highest straight line segment forming an angle with the width direction of the water collection tray 3, these values being: < β < , 0 < 45° and 20° β 60°. This adjustment ensures not only that the part of the projection on the first surface 31, which forms the lower straight line segment and the central straight line segment, has a certain inclination to guide the airflow and reduce the likelihood of eddy formation, but also prevents, despite a certain size in the front-back direction, the size in the top-down direction from becoming too large due to an excessively large inclination, thereby effectively reducing the space occupied by the water collection tray 3 in the top-down direction of the air supply channel 11. In particular, the angles formed between the lowest straight line segment and the width direction of the water collection tray 3 can be 10°, 25° and 45°, and the angles formed between the middle straight line segment and the width direction of the water collection tray 3 can be 20°, 40° and 60°, the angle between the highest straight line segment and the width direction of the water collection tray 3 can be 45°, 60° or 75°. In some embodiments, the polyline segment is also provided to comprise an arc segment, the upper end of the arc segment being connected to the lower end of the lowest straight line segment, and the lower end of the arc segment reaching to the lower edge of the outer wall surface of the water collection tray 3. In this way, the lower part of the first surface 31 can better conduct the airflow and the probability of eddy formation when the airflow flows through the first surface 31 is lower, and the air suction efficiency of the air conditioning equipment is higher. In particular, the outer wall surface of the water collection tray 3 also features an arched surface that is connected to the lower end of the first surface 31, the arched surface and the lower arched surface of the first surface 31 together form a downward-facing concave arched surface. In some embodiments, the water collection tray 3 is provided to also have a third surface 32, which is located opposite the second surface 21 in the width direction of the water collection tray 3, the third surface 32 being a vertical surface, the lower end of the third surface 32 being connected to the upper end of the first surface 31, the upper end of the third surface 32 reaching the upper surface of the water collection tray 3. Under the condition that the size of the first surface 31 in the up-down direction is constant, by adjusting the third surface 32 as a vertical surface, the situation of the maximum size of the water collection tray 3 in the front-back direction becoming too large is effectively avoided, and consequently, the width of the air supply spaces on the front and back side of the water collection tray 3 is affected, and the airflow flows more evenly through the air supply space on the side of the water collection tray 3 and the air supply efficiency of the air conditioning equipment is greater. In some embodiments, the water collection tray 3 and the base 1 are provided respectively with a fourth surface 33 and a fifth surface 12 that are positioned opposite each other in the width direction of the water collection tray 3, and the distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water collection tray 3 gradually decreases from bottom to top. Therefore, when the airflow flows through the air supply space at the rear of the water collection tray 3 upwards, it can conduct the airflow and simultaneously increase its airflow speed effectively, thereby ensuring the efficiency of the air supply. In some embodiments it is planned that the minimum distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water collection tray 3 is d, so that 15 mm d 40 mm. By adjusting the minimum distance between the fourth surface 33 and the fifth surface 12 in the front-back direction from 15 mm to 40 mm, it is possible to prevent, on the one hand, the width of the air supply space on the rear side of the water collection tray 3 from becoming too small and consequently increasing air resistance, and on the other hand, it is possible to prevent the width of the air supply space on the rear side of the water collection tray 3 from becoming too large and consequently reducing the air supply space on the front side of the water collection tray 3; consequently, a uniform airflow in the air supply spaces on the front and rear sides of the water collection tray 3 is effectively ensured. In particular, the minimum distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water collection tray 3 can be 15 mm, 30 mm or 40 mm.
