[0017] Embodiments of the present utility model are described in detail below; examples of these embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and serve to illustrate the present utility model, but should not be interpreted as limiting it.

[0018] The air conditioning system according to an embodiment of the present utility model is described below with reference to Fig. 1 described.

[0019] The air conditioning system according to an embodiment of the present utility model comprises a base 1, a central frame 2, and a water collection disc 3. The base 1 and the central frame 2 are connected to each other, enclosing and forming an air supply duct 11, and the water collection disc 3 is provided in the air supply duct 11. The water collection disc 3 and the central frame 2 each have a first surface 31 and a second surface 21, which are oriented in the lateral direction of the water collection disc 3 (the front-to-back direction). Fig. 1) are opposite each other, wherein each part of the first surface 31 forms an angle with the vertical surface, wherein the minimum distance between the first surface 31 and the second surface 21 in the width direction of the water collecting disc 3 is a, wherein the part of the first surface 31 which forms the largest angle with the horizontal plane forms an angle b with the second surface 21, wherein the part of the first surface 31 which forms the largest angle with the horizontal plane forms an angle c with the vertical surface, wherein 25 mm ≤ a ≤ 75 mm and / or 5° ≤ b ≤ 45° and / or 10° ≤ c ≤ 60° apply.

[0020] In the air conditioning system of the embodiments of the present utility model, the minimum distance between the first surface 31 and the second surface 21 in the front-to-back direction is set to 25 mm to 75 mm, wherein the portion of the first surface 31 forming the largest angle with the horizontal plane is set to form an angle between 5° and 45° with the second surface 21, and wherein the portion of the first surface 31 forming the largest angle with the horizontal plane is set to form an angle between 10° and 60° with the vertical surface. Each of the three aforementioned settings effectively ensures that sufficient air supply space is available at the front of the water collection disc 3, thereby ensuring that the airflow at the front of the water collection disc 3 flows smoothly with reduced air intake resistance.larger air intake volume and higher air supply efficiency.

[0021] It should be noted that the minimum distance between the first surface 31 and the second surface 21 in the front-to-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°; 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.

[0022] In some embodiments, it is provided that 35mm ≤ a ≤ 65mm and / or 20° ≤ b ≤ 30° and / or 25° ≤ c ≤ 45° apply.

[0023] By setting the minimum distance between the first surface 31 and the second surface 21 in the front-back direction to between 35 mm and 65 mm, it is possible, on the one hand, to prevent the width of the air supply space at the front of the water collection disc 3 from becoming too small and thus increasing wind resistance, and on the other hand, to prevent the width of the air supply space in front of the water collection disc 3 from becoming too large and thus reducing the air supply space at the rear of the water collection disc 3, thereby effectively ensuring a uniform airflow in the air supply spaces at the front and rear of the water collection disc 3.

[0024] 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 to 20° to 30°, on the one hand, the lower end of the front plate of the middle frame 2 is prevented from being tilted too far forward, which would reduce the width of the air supply space at the front of the water collection disc 3, and on the other hand, the lower end of the front plate of the middle frame 2 is prevented from being tilted too far forward, which would impair the aesthetic appearance of the middle frame 2.

[0025] By setting the angle between the part of the first surface 31 that forms the largest angle with the horizontal plane and the vertical surface to a value between 10° and 60°, every 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°, thereby effectively preventing the airflow from generating turbulence when passing through the first surface 31 and impairing the air supply efficiency.

[0026] In some embodiments, such as in Fig. As shown in Figure 1, the central frame 2 is provided with an air inlet hole 22 which communicates with the air supply channel 11, the air inlet hole 22 is located below the water collection disc 3 and extends to the lower surface of the central frame 2, wherein the minimum distance between the lower surface of the central frame 2 and the outer wall surface of the water collection disc 3 in the vertical direction of the water collection disc 3 is h, where 30 mm ≤ h ≤ 60 mm applies.

[0027] This setting prevents, on the one hand, the water collection disc 3 from being too close to the air inlet grille in the air inlet hole 22 and increasing the air intake resistance at the air inlet grille, and on the other hand, prevents the water collection disc 3 from being too close to the evaporator and impairing its water collection quantity.

[0028] Specifically, the distance between the lower surface of the middle frame 2 and the lowest point of the outer wall surface of the water collection disc 3 can be 30 mm, 45 mm and 60 mm.

[0029] In some embodiments, the distance between the first surface 31 and the second surface 21 gradually decreases from bottom to top in the width direction of the water collection disc 3.

[0030] Therefore, when the airflow flows upwards through the air supply space at the front of the water collection disc 3, it can guide the airflow and at the same time effectively increase its airflow velocity, thus effectively ensuring the air supply efficiency.

[0031] In some embodiments, such as in Fig.As shown in Figure 1, it is provided that on a projection surface perpendicular to the longitudinal direction of the water collecting disk 3 the projection contour of the first surface 31 is a polyline segment, wherein the polyline segment has several straight line segments that are connected one after the other from bottom to top, wherein the uppermost straight line segment forms an angle b with the second surface 21 and the uppermost straight line segment forms an angle c with the vertical surface.

[0032] This means that the inclination angle of the first surface 31 relative 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 b, the angle between any part of the first surface 31 and the vertical surface is greater than or equal to c, this setting ensures that the airflow has good guiding properties when passing through the first surface 31 and the probability of vortex formation is low, at the same time it ensures that there is a sufficiently wide air supply space at the front of the water collection disc 3 to guarantee a uniform airflow.

[0033] Specifically, the polyline segment also includes an arc segment, and any two adjacent straight line segments are smoothly connected by an arc segment.

[0034] In some embodiments, it is provided that three straight line segments are present and the lowest straight line segment forms an angle α with the width direction of the water collecting disc 3, wherein the middle straight line segment forms an angle β with the width direction of the water collecting disc 3 and the uppermost straight line segment forms an angle γ with the width direction of the water collecting disc 3, where α < β < γ, 0 < α ≤ 45°, 20° < β ≤ 60° apply.

[0035] This setting ensures both that the part of the projection in the first surface 31, which forms the lowest straight line segment and the middle straight line segment, has a certain inclination to guide the airflow and reduce the probability of vortex formation, and also that, despite a certain size in the front-back direction, the size in the top-bottom direction does not become too large due to an excessive inclination, thereby effectively reducing the space occupied by the water collecting disc 3 in the top-bottom direction of the air supply duct 11.

[0036] Specifically, the angles formed between the lowest straight line segment and the latitude direction of the water collecting disc 3 can be 10°, 25° and 45°, and the angles formed between the middle straight line segment and the latitude direction of the water collecting disc 3 can be 20°, 40° and 60°, and the angle formed between the uppermost straight line segment and the latitude direction of the water collecting disc 3 can be 45°, 60° or 75°.

[0037] In some embodiments, the polyline segment also includes an arc segment, wherein the upper end of the arc segment is connected to the lower end of the lowest straight line segment and the lower end of the arc segment extends to the lower edge of the outer wall surface of the water collection disc 3.

[0038] This allows the lower part of the first surface 31 to better guide the airflow, and the probability of vortex formation when the airflow passes through the first surface 31 is lower, and the air intake efficiency of the air conditioner is higher.

[0039] Specifically, the outer wall surface of the water collection disc 3 also has an arc surface which is connected to the lower end of the first surface 31; the arc surface and the lowest arc surface of the first surface 31 together form a downwardly concave arc surface.

[0040] In some embodiments, the water collecting disc 3 further comprises a third surface 32 which is opposite the second surface 21 in the width direction of the water collecting disc 3, wherein the third surface 32 is a vertical surface, wherein the lower end of the third surface 32 is connected to the upper end of the first surface 31, and wherein the upper end of the third surface 32 extends to the upper surface of the water collecting disc 3.

[0041] Provided that the size of the first surface 31 is constant in the top-bottom direction, setting the third surface 32 as a vertical surface effectively avoids the situation where the maximum size of the water collection disc 3 becomes too large in the front-back direction and thereby impairs the width of the air supply spaces at the front and back of the water collection disc 3, and the airflow flows more evenly through the air supply space on the side of the water collection disc 3 and the air supply efficiency of the air conditioning system is higher.

[0042] In some embodiments, the water collecting disc 3 and the base 1 are each provided with a fourth surface 33 and a fifth surface 12, which are opposite each other in the width direction of the water collecting disc 3, and the distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water collecting disc 3 gradually decreases from bottom to top.

[0043] Therefore, when the airflow flows upwards through the air supply space at the rear of the water collection disc 3, it can guide the airflow and at the same time effectively increase its airflow velocity, thus effectively ensuring the air supply efficiency.

[0044] In some embodiments, the minimum distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water collection disc 3 is d, where 15 mm ≤ d ≤ 40 mm applies.

[0045] By setting the minimum distance between the fourth surface 33 and the fifth surface 12 in the front-back direction to between 15mm and 40mm, it is possible, on the one hand, to prevent the width of the air supply space at the rear of the water collection disc 3 from becoming too small and thus increasing wind resistance, and on the other hand, to prevent the width of the air supply space at the rear of the water collection disc 3 from becoming too large and thus reducing the air supply space at the front of the water collection disc 3, thereby effectively ensuring a uniform airflow in the air supply spaces at the front and rear of the water collection disc 3.

[0046] Specifically, the minimum distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water collection disc 3 can be 15 mm, 30 mm or 40 mm.
