[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, and the base 1 and the middle frame 2 surround and 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 middle frame 2 respectively have a width direction of the water receiving tray 3 (such as Figure 1 The first surface 31 and the second surface 21 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 at an angle to the vertical plane, the minimum distance between the first surface 31 and the second surface 21 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 21, 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 25 mm ≤ a ≤ 75 mm, and / or 5° ≤ b ≤ 45°, and / or 10° ≤ c ≤ 60°.

[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 21 in the front-to-back direction to be between 25 mm and 75 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 21 to be between 5° and 45°, 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 to be between 10° and 60°, any of the above three settings can effectively ensure that the front side of the water receiving tray 3 has sufficient air supply space, ensure that the airflow passes smoothly in front 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 21 in the front-to-back direction can be 25 mm, 50 mm, and 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°, and 45°. 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 10°, 35°, and 60°. The portion of the first surface 31 that forms the largest angle with the horizontal plane has the largest slope.

[0024] In some embodiments, 35mm≤a≤65mm, and / or, 20°≤b≤30°, and / or, 25°≤c≤45°.

[0025] By setting the minimum distance between the first face 31 and the second face 21 in the front-rear direction to be between 35mm and 65mm, on the one hand, the width of the air supply space in front of 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 in front of the water tray 3 is prevented from being too large to reduce the air supply space in the rear side of the water tray 3, effectively ensuring the smoothness of the air flow in the air supply space in front and rear sides of 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 21 to be between 20° and 30°, on the one hand, the front end of the lower end of the front panel of the middle frame 2 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 front end of the lower end of the front panel of the middle frame 2 is prevented from being too large to affect the appearance of the middle frame 2.

[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 60°, 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 60°, 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 FIG. 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. Figure 1

[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 21 in the width direction of the water tray 3 gradually decreases from bottom to top.

[0032] Therefore, when the air flow passes through the air supply space in front of the water tray 3 upwards, 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 FIG. 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. Figure 1 ​As shown, in the projection plane perpendicular to the length direction of the water pan 3, the projection profile of the first surface 31 is a broken line segment, which includes a plurality of straight line segments connected in sequence from bottom to top, the straight line segment at the top is at an angle b with the second surface 21, and the straight line segment at the top is at an angle c with the vertical plane.

[0034] That is, the inclination angle of the first surface 31 with respect to the horizontal direction gradually increases from bottom to top, the angle between any part of the first surface 31 and the second surface 21 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 front side of the water pan 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 three, the straight line segment at the bottom is at an angle a with the width direction of the water pan 3, the straight line segment in the middle is at an angle b with the width direction of the water pan 3, and the straight line segment at the top is at an angle g with the width direction of the water pan 3, wherein a < b < g, 0 < a < 45°, and 20° < b < 60°.

[0037] This arrangement not only ensures that the part of the first surface 31 in which the straight line segment at the bottom and the straight line segment in the middle are projected 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 slope is too large to cause the size in the up-down direction to be too large on the basis of the size in the front-back direction being certain, thereby effectively reducing the space occupied by the water pan 3 in the up-down direction of the air supply channel 11.

[0038] Specifically, the angle between the straight line segment at the bottom and the width direction of the water pan 3 can be 10°, 25°, and 45°, the angle between the straight line segment in the middle and the width direction of the water pan 3 can be 20°, 40°, and 60°, and the angle between the straight line segment at the top and the width direction of the water pan 3 can be 45°, 60°, and 75°.

[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 straight line segment at the bottom, and the lower end of the arc segment extends to the lower edge of the outer wall surface of the water pan 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 pan 3 further comprises an arc surface connected with the lower end of the first surface 31, which together with the lowermost arc surface of the first surface 31 forms a downwardly concave arc surface.

[0042] In some embodiments, the water pan 3 further comprises a third surface 32 opposite to the second surface 21 in the width direction of the water pan 3, the third surface 32 being a vertical surface, the lower end of the third surface 32 being connected with the upper end of the first surface 31, and the upper end of the third surface 32 extending to the upper surface of the water pan 3.

[0043] Therefore, on the basis of the fixed size of the first surface 31 in the up-down direction, by setting the third surface 32 as a vertical surface, the maximum size of the water pan 3 in the front-rear direction is effectively avoided to be too large to affect the width of the air supply space on both sides of the water pan 3, and the airflow passing through the air supply space on the side of the water pan 3 is more smooth, and the air supply efficiency of the air conditioner is higher.

[0044] In some embodiments, the water pan 3 and the base 1 are respectively provided with a fourth surface 33 and a fifth surface 12 opposite to each other in the width direction of the water pan 3, and the distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water pan 3 gradually decreases from bottom to top.

[0045] Therefore, when the airflow passes through the air supply space on the rear side of the water pan 3, the airflow can be guided while its flow rate is effectively increased, thereby effectively ensuring the air supply efficiency.

[0046] In some embodiments, the minimum distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water pan 3 is d, wherein 15mm≤d≤40mm.

[0047] By setting the minimum distance between the fourth surface 33 and the fifth surface 12 in the front-rear direction to be between 15mm and 40mm, on the one hand, the width of the air supply space on the rear side of the water pan 3 is avoided to be too small to increase the air resistance, and on the other hand, the width of the air supply space on the rear side of the water pan 3 is avoided to be too large to reduce the air supply space on the front side of the water pan 3, thereby effectively ensuring the smoothness of the airflow in the air supply spaces on both sides of the water pan 3.

[0048] Specifically, the minimum distance between the fourth surface 33 and the fifth surface 12 in the width direction of the water pan 3 can be 15mm, 30mm and 40mm.
