[0025] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples and are intended to be illustrative of the present application and are not to be construed as limiting the present application.

[0026] The water pan 1 according to embodiments of the present application is described below with reference to the accompanying drawings. Figures 1-4 The water pan 1 according to embodiments of the present application is described below with reference to the accompanying drawings.

[0027] The water pan 1 according to embodiments of the present application is described below with reference to the accompanying drawings. Figure 1 The water pan 1 according to embodiments of the present application is described below with reference to the accompanying drawings.

[0028] The water pan 1 according to embodiments of the present application is described below with reference to the accompanying drawings.

[0029] Need to be explained, angle a can be 20°, 45°, 60° and 75°. In any two adjacent line segments in the first broken line segment, the line segment above forms an angle with the horizontal direction greater than the line segment below, and in any two adjacent line segments in the second broken line segment, the line segment above forms an angle with the horizontal direction greater than the line segment below. When the line segment is a straight line segment, the angle between the line segment and the horizontal direction is the angle between the extension direction of the line segment and the horizontal direction, and when the line segment is an arc line segment, the angle between the line segment and the horizontal direction is the angle between the extension direction of the tangent line at the upper end of the line segment and the horizontal direction.

[0030] In some embodiments, as Figure 2As shown, the first fold line segment includes a first arc line segment at the bottom, and the second fold line segment includes a second arc line segment at the bottom, and the first arc line segment and the second arc line segment are connected to form a downwardly concave arc line.

[0031] That is, the lower end of the first fold line segment and the lower end of the second fold line segment are directly connected, and at this time, the bottom surface of the disc body 11 is a downwardly concave arc surface, and when the airflow is blown from bottom to top to the bottom surface of the disc body 11, the airflow can be better guided to the front and rear sides of the disc body 11 by the first surface 111 and the second surface 112 respectively, further reducing the probability of vortex flow formed on the bottom surface of the disc body 11, and the air supply uniformity and air supply efficiency of the air conditioner are higher.

[0032] Specifically, the lower end of the first arc line segment and the lower end of the second arc line segment are both the lowest points of the outer wall surface of the disc body 11, and the tangent lines at the lower ends of the two are coincident, that is, the first arc line segment and the second arc line segment are smoothly connected.

[0033] It should be noted that in this embodiment, the lowermost line segment in any one of the first fold line segment and the second fold line segment can also be a straight line segment, and the air supply uniformity and air supply efficiency of the air conditioner are also high.

[0034] In some embodiments, as shown in FIG. 6, the first fold line segment further includes a first straight line segment connected to the upper end of the first arc line segment, and the angle between the first straight line segment and the width direction of the disc body 11 is α, where 0 < α ≤ 45°. Figure 2

[0035] This setting not only ensures that the part of the first surface 111 that projects to form the first straight line segment has a certain slope to guide the airflow and reduce the probability of vortex flow, 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-rear direction being certain, thereby effectively reducing the space occupied by the water pan 1 in the up-down direction of the air supply channel 21.

[0036] Specifically, the angle α between the first straight line segment and the width direction of the disc body 11 can be 10°, 25°, and 45°, and the tangent line at the upper end of the first straight line segment and the first arc line segment is coincident.

[0037] In some embodiments, as shown in FIG. 7, the first fold line segment further includes a second straight line segment connected to the upper end of the first straight line segment, and the angle between the second straight line segment and the width direction of the disc body 11 is β, where β > α, and 20° ≤ β ≤ 60°. Figure 2

[0038] ​​The setting ensures that the part of the first surface 111 that projects to form the second straight line segment has a greater slope than the part that forms the first straight line segment, so as to guide the airflow while further reducing the air inlet resistance; meanwhile, it also avoids the situation that the size in the up-down direction is too large due to the too large slope on the basis of the same size in the front-back direction, thereby effectively reducing the space occupied by the water pan 1 in the up-down direction of the air supply channel 21.

[0039] Specifically, the angle β between the second straight line segment and the width direction of the pan body 11 can be 20°, 40°, and 60°, and the second straight line segment is connected to the first straight line segment through another arc segment, and the tangent lines at the two ends of the arc segment coincide with the second straight line segment and the first straight line segment respectively.

[0040] In some embodiments, the first fold line segment further includes a third straight line segment connected to the upper end of the second straight line segment, and the angle γ between the third straight line segment and the width direction of the pan body 11 is 45°≤γ≤75°.

[0041] The setting ensures that the part of the first surface 111 that projects to form the second straight line segment has a greater slope than the part that forms the first straight line segment, so as to guide the airflow while further reducing the air inlet resistance; meanwhile, it also avoids the situation that the size in the up-down direction is too large due to the too large slope on the basis of the same size in the front-back direction, thereby effectively reducing the space occupied by the water pan 1 in the up-down direction of the air supply channel 21.

[0042] Specifically, the angle γ between the third straight line segment and the width direction of the pan body 11 can be 45°, 60°, and 75°, and the third straight line segment is connected to the second straight line segment through another arc segment, and the tangent lines at the two ends of the arc segment coincide with the third straight line segment and the second straight line segment respectively.

[0043] In some embodiments, as shown in Figure 2 The fourth straight line segment is connected to the upper end of the second arc segment, and the angle θ between the fourth straight line segment and the width direction of the pan body 11 is 15°≤θ≤60°.

[0044] The setting ensures that the part of the first surface 111 that projects to form the second straight line segment has a greater slope than the part that forms the first straight line segment, so as to guide the airflow while further reducing the air inlet resistance; meanwhile, it also avoids the situation that the size in the up-down direction is too large due to the too large slope on the basis of the same size in the front-back direction, thereby effectively reducing the space occupied by the water pan 1 in the up-down direction of the air supply channel 21.

[0045] Specifically, the angle θ between the fourth straight line segment and the width direction of the pan body 11 can be 15°, 45°, and 60°, and the tangent line at the upper end of the fourth straight line segment coincides with the second arc segment.

[0046] In some embodiments, as shown inFigure 2 As shown, the second fold line segment further comprises a fifth straight line segment connected with the upper end of the fourth straight line segment, and the angle between the fifth straight line segment and the width direction of the tray body 11 is δ, wherein 40°≤δ≤80°.

[0047] The arrangement ensures that the part of the second surface 112 that projects to form the fifth straight line segment has a greater slope than the part that forms the fourth straight line segment, so as to guide the airflow while further reducing the air inlet resistance; at the same time, it also avoids the situation that the size in the up-down direction is too large due to the too large slope on the basis of the same size in the front-rear direction, thereby effectively reducing the space occupied by the water collecting tray 1 in the up-down direction of the air supply passage 21.

[0048] Specifically, the angle δ between the fifth straight line segment and the width direction of the tray body 11 can be 40°, 60° and 80°, and the fifth straight line segment is connected with the fourth straight line segment through another arc segment, and the tangent lines at the upper and lower ends of the arc segment coincide with the fifth straight line segment and the fourth straight line segment, respectively.

[0049] It should be noted that the outer wall surface of the tray body 11 further comprises a first vertical surface and a second vertical surface opposite in the front-rear direction, the lower end of the first vertical surface is connected with the upper end of the first surface 111, and the lower end of the second vertical surface is connected with the upper end of the second surface 112.

[0050] The air conditioner according to the embodiment of the present application comprises a base 2, a middle frame 3, a first evaporator 4, a second evaporator 5 and a water collecting tray 1. The base 2 and the middle frame 3 are connected, and the base 2 and the middle frame 3 surround to form an air supply passage 21. The lower end of the first evaporator 4 and the lower end of the second evaporator 5 are connected and form an angle, and the first evaporator 4 and the second evaporator 5 are both located in the air supply passage 21. The water collecting tray 1 is arranged in the air supply passage 21 and located below the first evaporator 4 and the second evaporator 5, and the water collecting tray 1 is the water collecting tray 1 of any one of the above embodiments.

[0051] The technical advantages of the air conditioner according to the embodiment of the present application are the same as those of the water collecting tray 1 of the above embodiment, which will not be repeated here.

[0052] In some embodiments, as Figure 1 As shown, the middle frame 3 comprises a front panel 31, the first evaporator 4 is located on the side adjacent to the front panel 31 of the second evaporator 5, and the first evaporator 4 and the front panel 31 respectively have a thickness direction (such as the front-rear direction) perpendicular to the width direction of the base 2. Figure 1The third face 311 and the fourth face 41 are opposite to each other in the front-rear direction, the second evaporator 5 and the base 2 have a fifth face 51 and a sixth face 22 opposite to each other in the thickness direction of the base 2, the first face 111 is between the second face 112 and the fourth face 41 in the width direction of the disc body 11, the part of the first face 111 with the smallest angle with the vertical plane forms an angle b with the third face 311, the part of the first face 111 with the smallest angle with the vertical plane forms an angle c with the fourth face 41, the part of the second face 112 with the smallest angle with the vertical plane forms an angle d with the fifth face 51, and the part of the second face 112 with the smallest angle with the vertical plane forms an angle e with the sixth face 22, wherein b < c and / or d > e.

[0053] On the basis of the angles b and d, by setting b < c and d > e, the space between the third face 311 and the fourth face 41 is effectively increased, and the space between the fifth face 51 and the sixth face 22 is effectively increased, so that the air flow passing through the above-mentioned spaces is subjected to smaller resistance, and the air conditioning supply efficiency is higher.

[0054] Specifically, the part of the first face 111 with the smallest angle with the vertical plane is the part of the first face 111 that projects to form the third straight line segment, and the part of the second face 112 with the smallest angle with the vertical plane is the part of the second face 112 that projects to form the fifth straight line segment.

[0055] In some embodiments, 0° < b < 30°, 5° < c < 45°, 5° < d < 45°, and 0° < e < 30°.

[0056] This setting ensures that the space of the air supply channel 21 in front of the first evaporator 4 and the space in the rear of the second evaporator 5 are large enough, while avoiding that the fourth face 41 and the sixth face 22 are inclined at too large an angle, which would cause the air conditioner to be too large in the front-rear direction and affect user satisfaction.

[0057] Specifically, the angle b can be 5°, 15°, and 25°, and the angle d can be 10°, 25°, and 40°. Correspondingly, the angle c can be 10°, 20°, and 40°, and the angle e can be 5°, 15°, and 25°.

[0058] In some embodiments, as Figure 2 shown, the middle frame 3 is provided with an air inlet hole 32 communicating with the air supply channel 21, the air inlet hole 32 is located below the disc body 11 and extends to the lower surface of the middle frame 3, and the minimum distance between the lower surface of the middle frame 3 and the outer wall surface of the disc body 11 in the height direction of the disc body 11 (e.g. Figure 1 shown, the up-down direction) is h, wherein 30 mm ≤ h ≤ 60 mm.

[0059] The arrangement avoids that the distance between the water receiving tray 1 and the air inlet grille in the air inlet hole 32 in the up-down direction is too small to limit the air inlet area of the air inlet grille, and causes the air flow to pass through the air inlet grille and the water receiving tray 1 to have too large resistance; and also avoids that the distance between the water receiving tray 1 and the first evaporator 4 and the second evaporator 5 located above the water receiving tray 1 is too small to affect the water receiving amount of the water receiving tray 1, and effectively ensures the water receiving reliability of the water receiving tray 1.

[0060] Specifically, the distance h between the lowest point of the outer wall surface of the water receiving tray 1 and the lower surface of the middle frame 3 can be 30mm, 45mm and 60mm.
