[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The following combination Figure 1 An air conditioner according to an embodiment of the present invention is described.

[0021] The air conditioner of the present invention comprises a base 1, a middle frame 2 and a water receiving tray 3. The base 1 and the middle frame 2 are connected to form an air supply channel 11. The water receiving tray 3 is arranged in the air supply channel 11. The water receiving tray 3 and the base 1 have a width direction of the water receiving tray 3 (such as Figure 1 The first surface 31 and the second surface 12 are opposite to each other in the front-to-back direction (in the front-to-back direction), any part of the first surface 31 is angled with the vertical plane, the minimum distance between the first surface 31 and the second surface 12 in the width direction of the water receiving tray 3 is a, the part of the first surface 31 that forms the largest angle with the horizontal plane forms an angle b with the second surface 12, and the part of the first surface 31 that forms the largest angle with the horizontal plane forms an angle c with the vertical plane, wherein 15mm≤a≤40mm, and / or, 0°≤b≤30°, and / or, 5°≤c≤45°.

[0022] According to the air conditioner of the embodiment of the present invention, by setting the minimum distance between the first surface 31 and the second surface 12 in the front-to-back direction between 15 mm and 40 mm, by setting the angle between the portion of the first surface 31 that forms the largest angle with the horizontal plane and the second surface 12 between 0° and 30°, and by setting the angle between the portion of the first surface 31 that forms the largest angle with the horizontal plane and the vertical plane between 5° and 45°, any of the above three settings can effectively ensure that the rear side of the water receiving tray 3 has sufficient air supply space, ensure that the airflow passes smoothly at the rear side of the water receiving tray 3, have smaller air intake resistance, larger air intake volume, and higher air supply efficiency.

[0023] It should be noted that the minimum distance between the first surface 31 and the second surface 12 in the front-to-back direction can be 15 mm, 30 mm, or 40 mm. The angle between the portion of the first surface 31 that forms the largest angle with the horizontal plane and the second surface 12 can be 5°, 15°, or 30°. The angle between the portion of the first surface 31 that forms the largest angle with the horizontal plane and the vertical plane can be 5°, 25°, or 45°. The portion of the first surface 31 that forms the largest angle with the horizontal plane has the largest slope.

[0024] In some embodiments, 20mm≤a≤35mm, and / or, 5°≤b≤25°, and / or, 10°≤c≤35°.

[0025] By setting the minimum distance between the first face 31 and the second face 12 in the front-rear direction to be between 20mm and 35mm, on the one hand, the width of the air supply space behind the water tray 3 is prevented from being too small to increase the air resistance, and on the other hand, the width of the air supply space behind the water tray 3 is prevented from being too large to reduce the air supply space in front of the water tray 3, effectively ensuring the smoothness of the air flow in the air supply space in front of and behind the water tray 3.

[0026] By setting the angle between the part of the first face 31 with the largest angle with the horizontal plane and the second face 12 to be between 5° and 25°, on the one hand, the slope of the second face 12 is prevented from being too small to reduce the width of the air supply space in front of the water tray 3, and on the other hand, the slope of the second face 12 is prevented from being too large to affect the guiding effect of the air flow.

[0027] By setting the angle between the part of the first face 31 with the largest angle with the horizontal plane and the vertical plane to be between 10° and 35°, the parts of the first face 31 are all inclined surfaces with an angle with the horizontal direction, and the maximum angle is not more than 35°, thereby effectively preventing the air flow from generating vortex when passing through the first face 31 to affect the air supply efficiency.

[0028] In some embodiments, as shown in Figure 1 The middle frame 2 is provided with an air inlet hole 22 communicating with the air supply channel 11, the air inlet hole 22 is located below the water tray 3 and extends to the lower surface of the middle frame 2, and the minimum distance between the lower surface of the middle frame 2 and the outer wall surface of the water tray 3 in the height direction of the water tray 3 is h, wherein 30mm≤h≤60mm.

[0029] This setting, on the one hand, prevents the water tray 3 from being too close to the air inlet grille in the air inlet hole 22 to increase the air inlet resistance of the air flow at the air inlet grille, and on the other hand, prevents the water tray 3 from being too close to the evaporator upwards to affect the water receiving amount of the evaporator.

[0030] Specifically, the distance between the lower surface of the middle frame 2 and the lowest point of the outer wall surface of the water tray 3 can be 30mm, 45mm and 60mm.

[0031] In some embodiments, the distance between the first face 31 and the second face 12 in the width direction of the water tray 3 gradually increases from bottom to top.

[0032] Therefore, when the air flow passes through the air supply space behind the water tray 3, the air flow can be guided while the air flow speed is effectively improved, thereby effectively ensuring the air supply efficiency.

[0033] In some embodiments, as shown in Figure 1As shown, in the projection plane perpendicular to the length direction of the water tray 3, the projection profile of the first surface 31 is a broken line segment, which includes at least two straight line segments connected in sequence from bottom to top, the uppermost straight line segment forms an angle b with the second surface 12, and the uppermost straight line segment forms an angle c with the vertical plane.

[0034] That is, the inclination angle of the first surface 31 relative to the horizontal direction gradually increases from bottom to top, the angle between any part of the first surface 31 and the second surface 12 is greater than or equal to b, and the angle between any part of the first surface 31 and the vertical plane is greater than or equal to c. This arrangement ensures that the airflow is well directed when passing through the first surface 31, and the probability of vortex formation is low, while also ensuring that the rear side of the water tray 3 has a sufficient width of the air supply space to ensure the smoothness of the airflow.

[0035] Specifically, the broken line segment further includes an arc segment, and any two adjacent straight line segments are smoothly connected by an arc segment.

[0036] In some embodiments, the number of straight line segments is two, the lower straight line segment forms an angle a with the width direction of the water tray 3, and the upper straight line segment forms an angle b with the width direction of the water tray 3, wherein a < b, 15° < a < 60°.

[0037] This arrangement not only ensures that the part of the first surface 31 whose projection forms the lowermost straight line segment has a certain slope to achieve the guidance of the airflow and reduce the probability of vortex formation, but also avoids the situation that the size in the front-rear direction is constant, and the slope is too large, resulting in the size in the up-down direction being too large, thereby effectively reducing the space occupied by the water tray 3 in the up-down direction of the air supply channel 11.

[0038] Specifically, the angle between the lowermost straight line segment and the width direction of the water tray 3 can be 15°, 30°, 45°, and 60°.

[0039] In some embodiments, the broken line segment further includes an arc segment, the upper end of the arc segment is connected to the lower end of the lower straight line segment, and the lower end of the arc segment extends to the lower edge of the outer wall surface of the water tray 3.

[0040] Therefore, the part of the first surface 31 at the bottom can better guide the airflow, 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.

[0041] Specifically, the outer wall surface of the water tray 3 further includes an arc surface connected to the lower end of the first surface 31, and the arc surface and the lowermost arc surface of the first surface 31 together form a downwardly concave arc surface.

[0042] In some embodiments, the water receiving tray 3 also includes a third surface 32 opposite to the second surface 12 in the width direction of the water receiving tray 3. The third surface 32 is a vertical surface. The lower end of the third surface 32 is connected to the upper end of the first surface 31, and the upper end of the third surface 32 extends to the upper surface of the water receiving tray 3.

[0043] Therefore, on the basis of the certain dimensions of the first surface 31 in the up and down directions, by setting the third surface 32 as a vertical surface, it is effectively avoided that the maximum dimension of the water receiving tray 3 in the front and back directions is too large, which affects the width of the air supply space on the front and back sides of the water receiving tray 3. The airflow passes through the air supply space on the side of the water receiving tray 3 more smoothly, and the air supply efficiency of the air conditioner is higher.

[0044] In some embodiments, the water receiving tray 3 and the middle frame 2 are respectively provided with a fourth surface 33 and a fifth surface 21 opposite to each other in the width direction of the water receiving tray 3, and the minimum distance between the fourth surface 33 and the fifth surface 21 in the width direction of the water receiving tray 3 is d, where 25mm≤d≤75mm.

[0045] By setting the minimum distance between the fourth surface 33 and the fifth surface 21 in the front-to-back direction between 25 mm and 75 mm, on the one hand, it is possible to avoid the width of the air supply space on the front side of the water receiving tray 3 being too small to increase the wind resistance, and on the other hand, it is possible to avoid the width of the air supply space on the front side of the water receiving tray 3 being too large to reduce the air supply space on the rear side of the water receiving tray 3, thereby effectively ensuring the smoothness of the air supply in the air supply spaces on both sides of the water receiving tray 3.

[0046] Specifically, the distance between the fourth surface 33 and the fifth surface 21 in the width direction of the water receiving tray 3 gradually decreases from bottom to top, and the minimum distance between the fourth surface 33 and the fifth surface 21 in the width direction of the water receiving tray 3 can be 15 mm, 30 mm and 40 mm.

[0047] In some embodiments, as Figure 1 As shown, the base 1 also includes a sixth surface 13 opposite to the second surface 12 in the width direction of the water receiving tray 3. The sixth surface 13 is a vertical surface. The minimum distance between the sixth surface 13 and the first surface 31 in the width direction of the water receiving tray 3 is e, where 50mm≤e≤80mm.

[0048] On the basis that the rear side surface of the base 1 is a vertical surface, by setting the minimum width between the sixth surface 13 and the first surface 31 between 50 mm and 80 mm, on the one hand, the thickness of the rear side wall of the base 1 is avoided from being too small to affect the structural strength of the base 1, and on the other hand, the width of the rear air supply space of the water receiving tray 3 is avoided from being too small to affect the smoothness of the airflow. When the airflow passes through the rear air supply space of the water receiving tray 3, the wind resistance it encounters is smaller and the air supply efficiency is higher.

[0049] Specifically, the minimum distance between the sixth surface 13 and the first surface 31 in the width direction of the water receiving tray 3 can be 50 mm, 65 mm, and 80 mm.
