[0060] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0061] like Figure 1-Figure 11 As shown, an embodiment of the present application provides a water receiving tray 100, which can be used in an indoor unit of an air conditioner.

[0062] The water receiving tray 100 includes a water receiving tray body 1, which includes a water receiving tray body and an air guide portion 11. The air guide portion 11 is arranged on the air outlet side of the water receiving tray body and is arranged to guide the airflow to the air outlet 203. The first end of the air guide portion 11 is connected to the water receiving tray body, and the second end of the air guide portion 11 extends downward.

[0063] In the water receiving pan 100, the water receiving pan body of the water receiving pan main body 1 is mainly used to receive the condensed water generated on the heat exchanger (such as the first heat exchanger 301 and / or the second heat exchanger 302 described below) of the indoor unit of the air conditioner. When the indoor unit of the air conditioner is working, the air will flow over the water receiving pan 100, and the side where the air flows out of the water receiving pan body is the air outlet side of the water receiving pan body (at the bottom of the water receiving pan body). Figure 1 , Figure 2 and Figure 4 In the figure, the left side of the water receiving tray is the air outlet side of the water receiving tray). An air guide portion 11 is provided on the air outlet side of the water receiving tray, a first end of the air guide portion 11 is connected to the water receiving tray, and a second end of the air guide portion 11 extends downward, so that the air guide portion 11 can guide the airflow flowing out of the air outlet side of the water receiving tray to the air outlet 203, so that part of the airflow can flow close to the inner wall surface of the air outlet 203, avoiding the airflow from being concentrated in the middle of the air outlet 203, which is conducive to improving the uneven distribution of wind speed at the air outlet 203, and further helps to improve the noise, condensation and other problems of the air outlet 203.

[0064] In the embodiment of the present application, by adding an air guide portion 11 to the water receiving tray body, it helps to guide the airflow flowing out from the air outlet side of the water receiving tray body to flow on the inner wall near the air outlet 203, thereby increasing the distribution range of the airflow in the air outlet 203 and alleviating the phenomenon of uneven airflow distribution at the air outlet 203.

[0065] In some exemplary embodiments, Figure 3 As shown, the side wall of the air guide portion 11 facing away from the water receiving tray forms an air guide surface 111, and the air guide surface 111 is arc-shaped (such as circular arc shape). The radius c of the arc-shaped air guide surface 111 can be not less than 6 mm, such as 10 mm. Of course, the radius c of the air guide surface 111 is not limited to the aforementioned range, and the speed coefficient can be changed according to the wind speed.

[0066] The side wall of the air guide portion 11 facing away from the water receiving tray forms an air guide surface 111, and the air guide surface 111 is arc-shaped, so that the air flow flowing out from the air outlet side of the water receiving tray can flow smoothly along the arc-shaped air guide surface 111, avoiding sudden changes in the direction of the air flow and turbulence, which would lead to problems such as high noise and small air output.

[0067] In some exemplary embodiments, Figure 2 and Figure 3As shown, the tangent of the second end of the air guide surface 111 is in a vertical state, and the tangent can be parallel to the vertical inner wall surface of the air outlet 203, so that the air flow flowing out from the air outlet side of the water receiving tray can flow smoothly along the curved air guide surface 111 into the air outlet 203.

[0068] In some exemplary embodiments, the height difference between the first end and the second end of the wind guide surface 111 may be not less than 5 mm, such as 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, etc. Of course, the height difference between the first end and the second end of the wind guide surface 111 is not limited to the aforementioned range and can be adjusted as needed.

[0069] In some exemplary embodiments, Figure 1-Figure 4 As shown, the water receiving tray includes a water blowing prevention portion 12 , a first end of the water blowing prevention portion 12 is connected to a first end of the wind guide portion 11 , and a second end of the water blowing prevention portion 12 extends obliquely downward in a direction away from the wind guide portion 11 .

[0070] The water receiving tray body includes a water blowing prevention portion 12, a first end (e.g., the left end) of the water blowing prevention portion 12 is connected to a first end of the air guiding portion 11, and a second end (e.g., the right end) of the water blowing prevention portion 12 extends obliquely downward in a direction away from the air guiding portion 11. Along the direction toward the air outlet side of the water receiving tray body, the water blowing prevention portion 12 gradually tilts upward, that is, the water blowing prevention portion 12 is provided with a certain slope, which can prevent the condensed water in the water receiving tray body from being discharged from the air outlet side of the water receiving tray body, thereby preventing the water blowing phenomenon from occurring at the air outlet 203. In addition, the first end of the water blowing prevention portion 12 is connected to the first end of the air guiding portion 11, so that the airflow can enter the air outlet 203 under the guidance of the air guiding portion 11 after flowing out of the water receiving tray body along the water blowing prevention portion 12.

[0071] In some exemplary embodiments, Figure 3 As shown, the upper wall surface of the water-blowing prevention part 12 forms a water retaining surface 121, and the water retaining surface 121 is an inclined plane. The angle d between the water retaining surface 121 and the horizontal plane is greater than or equal to 110° and less than 170°.

[0072] The value range of the angle d between the water retaining surface 121 of the water-blowing prevention part 12 and the horizontal plane is: 110°≤d<170°, such as: the angle d can be 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, etc. The water retaining surface 121 can effectively prevent condensed water from being blown out and avoid water blowing from the air outlet 203, and also minimize the impact on the flowing airflow.

[0073] It should be understood that the angle d between the water retaining surface 121 of the water-blowing prevention part 12 and the horizontal plane is not limited to the above range, and can be adjusted by coefficient superposition according to the actual wind speed and wind volume.

[0074] In some exemplary embodiments, Figure 1-Figure 4 As shown, the water receiving tray body further includes a reflecting portion 13 for reflecting airflow, the reflecting portion 13 is located on a side of the water blowing prevention portion 12 away from the air guiding portion 11, and one end of the reflecting portion 13 away from the water blowing prevention portion 12 extends obliquely downward. The upper wall surface of the reflecting portion 13 forms a reflecting surface 131, and the reflecting surface 131 is an inclined plane or an arc-shaped surface convex upward.

[0075] A reflecting portion 13 is provided on one side (such as the right side) of the water-blow-proof portion 12 away from the wind-guiding portion 11, and the reflecting portion 13 can be used to reflect the airflow blowing onto its surface. The end (such as the right end) of the reflecting portion 13 away from the water-blow-proof portion 12 extends obliquely downward, and the reflecting surface 131 formed by the upper wall of the reflecting portion 13 can be an inclined plane, or an upwardly convex curved surface. Compared to the reflecting surface 131 being a downwardly concave curved surface, which causes the airflow to be blown onto the reflecting surface 131 and emitted, the airflow will gather in the water receiving tray body, forming a vortex and affecting the air output. The reflecting surface 131 of the embodiment of the present application adopts an inclined plane or an upwardly convex curved surface. When the airflow blows onto the reflecting surface 131, the airflow will be rebounded upward, which helps the airflow to flow outward and increases the air output.

[0076] In some exemplary embodiments, Figure 3 As shown, the reflecting surface 131 is an inclined plane, and the angle b between the reflecting surface 131 and the horizontal plane can be set to be greater than 0° and less than or equal to 15°, such as: the angle b can be 1°, 3°, 5°, 8°, 10°, 13°, 15°, etc.

[0077] Of course, the value range of the angle b is not limited to the above, and can also be adjusted according to actual needs.

[0078] In some exemplary embodiments, Figure 1-Figure 4 As shown, the water collecting tray body also includes a water collecting portion 14, a water collecting cavity 141 is formed in the water collecting portion 14, the water collecting portion 14 is located on the side of the reflecting portion 13 away from the anti-blow water portion 12, and the side wall of the water collecting portion 14 close to the reflecting portion 13 forms a water guiding slope and is connected to the reflecting portion 13, and the side wall of the water collecting portion 14 away from the reflecting portion 13 includes a first supporting portion 143, and the first supporting portion 143 is configured to support the first heat exchanger 301.

[0079] The water collecting chamber 141 of the water collecting portion 14 can be used to collect condensed water. The water collecting portion 14 is located on the side of the reflecting portion 13 away from the anti-blowing water portion 12 (such as the right side), wherein the water guiding slope of the water collecting portion 14 close to the reflecting portion 13 (such as the left side) can be connected to the reflecting portion 13, so that the condensed water on the inclined anti-blowing water portion 12, the reflecting portion 13 and the water guiding slope can flow into the water collecting chamber 141 under the action of gravity; the first supporting portion 143 of the water collecting portion 14 away from the side of the reflecting portion 13 (such as the right side) can be used to support the first heat exchanger 301, so that the water receiving tray can receive the condensed water dripping from the first heat exchanger 301.

[0080] In some exemplary embodiments, Figure 3 As shown, the upper wall surface of the first supporting portion 143 forms a first supporting surface 144, and the first supporting surface 144 is an inclined plane. The angle between the first supporting surface 144 and the horizontal plane is 30°-60°, so that the angle a between the first heat exchanger 301 supported on the first supporting surface 144 and the horizontal plane is 30°-60°, such as: the angle a can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. The size of the angle a can be determined according to the size (such as length) of the first heat exchanger 301 and the height of the housing 200 of the air conditioner indoor unit, thereby determining the angle between the first supporting surface 144 and the horizontal plane (complementary to the angle a).

[0081] Of course, the value ranges of the angle between the first supporting surface 144 and the horizontal plane and the angle a are not limited to the above, and can also be adjusted according to actual needs.

[0082] In some exemplary embodiments, Figure 3 As shown, the height difference g between the side of the reflecting surface 131 away from the water collecting portion 14 and the lowest point of the water collecting cavity 141 is not less than 10 mm.

[0083] The height difference g between the side of the reflective surface 131 away from the water collecting portion 14 and the lowest point of the water collecting chamber 141 can be set according to the specific drainage height of the water receiving tray 100, and can be set to not less than 10 mm. Of course, the value range of the height difference g is not limited to the above, and can also be adjusted according to actual needs.

[0084] In some exemplary embodiments, Figure 3 As shown, along the first horizontal direction from the windward side of the water receiving tray 100 to the leeward side (e.g., from right to left), the horizontal distance between the side of the reflecting surface 131 close to the water collecting portion 14 and the lowest point of the water collecting chamber 141 is r, and the total height of the water receiving tray 100 is n. The relationship between the two is: r=n / 3.

[0085] r is the distance between the left end of the reflecting surface 131 of the reflecting part 13 and the lowest point of the water collecting chamber 141. To meet the performance of the first heat exchanger 301, r=n / 3 can be set. Of course, the relationship between r and n is not limited to the above, and can be adjusted according to actual needs.

[0086] In some exemplary embodiments, Figure 1-Figure 3 As shown, the water receiving tray body further includes a second supporting portion 15 , the second supporting portion 15 is located between the reflecting portion 13 and the water blowing prevention portion 12 , and the second supporting portion 15 is configured to support the second heat exchanger 302 .

[0087] A second supporting portion 15 can be arranged between the reflecting portion 13 and the anti-blowing water portion 12 of the water receiving tray body, that is, along the first horizontal direction from the windward side of the water receiving tray 100 to the leeward side (such as: from right to left), the reflecting portion 13, the second supporting portion 15 and the anti-blowing water portion 12 can be arranged in sequence and connected, and the second supporting portion 15 can be used to support the second heat exchanger 302, so that the water receiving tray 100 can be adapted to the two heat exchangers (the first heat exchanger 301 and the second heat exchanger 302) and receive the condensed water on the two heat exchangers.

[0088] Of course, the water receiving tray body may also not include the second supporting portion 15. Figure 4 As shown, at this time, the reflecting portion 13 of the water receiving tray body can be connected to the anti-blow water portion 12.

[0089] In some exemplary embodiments, Figure 1-Figure 3 As shown, the upper wall surface of the second supporting portion 15 forms a second supporting surface 151 , and the second supporting surface 151 is a horizontal surface, so that the second heat exchanger 302 supported on the second supporting surface 151 is vertically arranged.

[0090] In some exemplary embodiments, Figure 3 As shown, along the first horizontal direction from the windward side to the leeward side of the water tray 100 (eg, from right to left), the horizontal dimension f of the second support surface 151 is not less than 15 mm.

[0091] The horizontal dimension f of the second support surface 151 can be determined according to actual needs, such as being set according to the horizontal dimension of the second heat exchanger 302 to facilitate installation of the second heat exchanger 302. Of course, the range of the horizontal dimension f of the second support surface 151 is not limited to the above, and can be adjusted according to actual needs.

[0092] In some exemplary embodiments, Figure 5-Figure 9 As shown, the first supporting surface 144 formed by the upper wall surface of the first supporting portion 143 is provided with a first water guiding cavity 145 which is recessed downward.

[0093] The first supporting surface 144 of the first supporting portion 143 contacts the lower end surface of the first heat exchanger 301 , and a first water guiding cavity 145 is provided on the first supporting surface 144 , so that condensed water sliding down from the first heat exchanger 301 to the first supporting surface 144 can be collected in the first water guiding cavity 145 , and flow from the first water guiding cavity 145 into the water collecting cavity 141 .

[0094] In some exemplary embodiments, Figure 5-Figure 9 As shown, a plurality of (e.g., two or more) first wind shielding ribs 146 are provided in the first water guiding cavity 145, and the upper end surfaces of the plurality of first wind shielding ribs 146 do not protrude from the first supporting surface 144; the first ends of the plurality of first wind shielding ribs 146 are alternately connected to the opposite side walls of the first water guiding cavity 145, and the second ends of the plurality of first wind shielding ribs 146 are staggered and overlapped, and a water-passing gap is formed between the second ends of adjacent first wind shielding ribs 146.

[0095] A plurality of first wind shielding ribs 146 are provided in the first water guiding cavity 145, and the upper end surfaces of the plurality of first wind shielding ribs 146 do not protrude from the first supporting surface 144, such as: the upper end surfaces of the plurality of first wind shielding ribs 146 may be flush with the first supporting surface 144 or lower than the first supporting surface 144, so that the setting of the first wind shielding ribs 146 will not affect the support of the first supporting surface 144 to the first heat exchanger 301.

[0096] The first ends of the plurality of first wind shielding ribs 146 are alternately connected to the opposite side walls of the first water guiding cavity 145, the second ends of the plurality of first wind shielding ribs 146 are staggered and overlapped, and a water-passing gap is formed between the second ends of adjacent first wind shielding ribs 146, wherein the second ends of the first wind shielding ribs 146 can be inclined relative to the first ends thereof toward the side where the bottom surface 147 of the water collecting cavity 141 is located, so that the condensed water collected in the first water guiding cavity 145 can pass through the water-passing gap between the first wind shielding ribs 146, and flow into the water collecting cavity 141 under the guidance of the first wind shielding ribs 146. In addition, the second ends of the plurality of first wind shielding ribs 146 are staggered and overlapped, so that the first wind shielding ribs 146 can play a role of wind shielding, preventing the airflow from flowing through the first water guiding cavity 145 below the first heat exchanger 301 without passing through the first heat exchanger 301, thereby affecting the heat exchange efficiency of the first heat exchanger 301.

[0097] Therefore, the first wind-shielding ribs 146 are arranged in a staggered pattern, which can pass water but not wind.

[0098] In some exemplary embodiments, Figure 5-Figure 7 As shown, the second support surface 151 formed by the upper wall of the second support portion 15 and the reflective surface 131 formed by the upper wall of the reflective portion 13 are respectively provided with a second water guide cavity 152 and a third water guide cavity 132 recessed downwards, and the second water guide cavity 152 and the third water guide cavity 132 are connected.

[0099] The second supporting surface 151 of the second supporting portion 15 contacts the lower end surface of the second heat exchanger 302, and a second water guiding cavity 152 and a third water guiding cavity 132 are respectively provided on the second supporting surface 151 and the reflecting surface 131 of the reflecting portion 13, and the second water guiding cavity 152 and the third water guiding cavity 132 are communicated, so that condensed water sliding down from the second heat exchanger 302 to the second supporting surface 151 or condensed water flowing back from the anti-blow water portion 12 to the second supporting surface 151 can be collected in the second water guiding cavity 152 and flow to the third water guiding cavity 132 communicated with the second water guiding cavity 152, so that the third water guiding cavity 132 flows into the water collecting cavity 141.

[0100] In some exemplary embodiments, Figure 5-Figure 7 As shown, a plurality of second wind-shielding ribs 153 are provided in the second water-guiding cavity 152, and the upper end surfaces of the plurality of second wind-shielding ribs 153 do not protrude from the second supporting surface 151; the first ends of the plurality of second wind-shielding ribs 153 are alternately connected to the opposite side walls of the second water-guiding cavity 152, and the second ends of the plurality of second wind-shielding ribs 153 are staggered and overlapped, and water-passing gaps are formed between the second ends of adjacent second wind-shielding ribs 153.

[0101] A plurality of second wind shielding ribs 153 are provided in the second water guiding cavity 152, and the upper end surfaces of the plurality of second wind shielding ribs 153 do not protrude from the second supporting surface 151, such as: the upper end surfaces of the plurality of second wind shielding ribs 153 may be flush with the second supporting surface 151 or lower than the second supporting surface 151, so that the setting of the second wind shielding ribs 153 will not affect the support of the second supporting surface 151 for the second heat exchanger 302.

[0102] The first ends of the plurality of second wind shielding ribs 153 are alternately connected to the opposite side walls of the second water guiding cavity 152, the second ends of the plurality of second wind shielding ribs 153 are staggered and overlapped, and a water-passing gap is formed between the second ends of adjacent second wind shielding ribs 153, wherein the second ends of the second wind shielding ribs 153 are inclined relative to the first ends thereof toward the side where the reflecting surface 131 is located, so that the condensed water collected in the second water guiding cavity 152 can pass through the water-passing gap between the second wind shielding ribs 153, and can flow into the third water guiding cavity 132 under the guidance of the second wind shielding ribs 153, and finally flow into the water collecting cavity 141. In addition, the second ends of the plurality of second wind shielding ribs 153 are staggered and overlapped, so that the second wind shielding ribs 153 can play a role in shielding the wind, preventing the airflow from flowing through the second water guiding cavity 152 below the second heat exchanger 302 without passing through the second heat exchanger 302, thereby affecting the heat exchange efficiency of the second heat exchanger 302, and preventing the condensed water from being blown out by the airflow, resulting in the problem of water blowing from the air outlet 203.

[0103] Therefore, the second wind shielding ribs 153 are arranged in a staggered pattern, which can pass water but not wind.

[0104] In some exemplary embodiments, Figure 5 and Figure 6 As shown, along a second horizontal direction perpendicular to the first horizontal direction, the second water guiding cavity 152 can be centrally arranged on the second supporting surface 151, and the first water guiding cavity 145 can be staggered with the second water guiding cavity 152 to prevent condensed water in the first water guiding cavity 145 and the second water guiding cavity 152 from flowing to the same position of the water collecting cavity 141.

[0105] In some exemplary embodiments, Figure 5 , Figure 6 and Figure 8 As shown, the water tray body 1 further includes a drainage area 16, which is arranged side by side with the water collecting portion 14 along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction from the windward side to the leeward side of the water tray 100. The drainage area 16 is connected to the water collecting cavity 141.

[0106] The water receiving tray body 1 includes not only the water receiving tray body but also a drainage area 16 , which can be communicated with the water collecting chamber 141 so that the condensed water collected in the water collecting chamber 141 can flow into the drainage area 16 and be discharged to the outside through the drainage area 16 .

[0107] In some exemplary embodiments, Fig. 9 As shown, the bottom surface 147 of the water collecting chamber 141 is arranged to be inclined downward along the direction from the water collecting portion 14 toward the drainage area 16, and the angle u between the bottom surface 147 of the water collecting chamber 141 and the horizontal plane is 1°-3°, such as: the angle u can be 1.15°, 1.5°, 1.8°, 2°, 2.3°, 2.5°, 2.8°, 3°, etc.

[0108] The bottom surface 147 of the water collecting chamber 141 can be tilted downward from the water collecting portion 14 toward the drainage area 16, so that the condensed water in the water collecting chamber 141 can flow into the drainage area 16 under the action of gravity. The angle u between the bottom surface 147 of the water collecting chamber 141 and the horizontal plane is 1°-3°, which can prevent the angle u from being too large to affect the volume of the water collecting chamber 141.

[0109] In some exemplary embodiments, Figure 5-Figure 6 , Figure 8-Figure 9 As shown, the bottom surface 147 of the water collecting chamber 141 is provided with a plurality of third wind shielding ribs 148, and the plurality of third wind shielding ribs 148 are close to the connecting parts between the drainage area 16 and the water collecting chamber 141; the first ends of the plurality of third wind shielding ribs 148 are alternately connected to the opposite side walls of the water collecting chamber 141, the second ends of the plurality of third wind shielding ribs 148 are staggered and overlapped, and water-passing gaps are formed between the second ends of adjacent third wind shielding ribs 148.

[0110] The plurality of third wind shielding ribs 148 provided on the bottom surface 147 of the water collecting chamber 141 are close to the connecting part between the drainage area 16 and the water collecting chamber 141, and the first ends of the plurality of third wind shielding ribs 148 are alternately connected to the opposite side walls of the water collecting chamber 141, and the second ends of the plurality of third wind shielding ribs 148 are staggered and overlapped, and a water-passing gap is formed between the second ends of adjacent third wind shielding ribs 148, wherein the second ends of the third wind shielding ribs 148 are inclined relative to the first ends toward the side where the drainage area 16 is located, so that the condensed water in the water collecting chamber 141 can pass through the water-passing gap between the third wind shielding ribs 148, and can flow into the drainage area 16 under the guidance of the third wind shielding ribs 148. In addition, the second ends of the plurality of third wind shielding ribs 148 are staggered and overlapped, so that the third wind shielding ribs 148 can play a role in wind protection, and the third wind shielding ribs can also prevent the dirt in the water collecting chamber 141 from entering the drainage area 16, thereby affecting the operation of the drainage pump.

[0111] Therefore, the third wind shield ribs 148 are arranged in a staggered pattern to pass water but not wind and block dirt.

[0112] In some exemplary embodiments, Figure 5 and Figure 6 As shown, the water receiving tray body 1 further includes a drainage protection area 17 located on the leeward side of the drainage area 16 . The drainage protection area 17 is higher than the drainage area 16 and is in communication with the drainage area 16 .

[0113] A drainage protection area 17 is provided on the leeward side of the drainage area 16. The drainage protection area 17 is higher than the drainage area 16 and is connected to the drainage area 16, so that when the drainage of the drainage area 16 fails or there is too much condensed water, the condensed water can overflow into the drainage protection area 17, thereby preventing the condensed water from overflowing the water receiving tray 100.

[0114] like Figure 6 As shown, the water receiving tray body 1 of the embodiment of the present application can be divided into five areas according to functional areas: an air guide area 31, a wind and condensate adjustment area 32, a drainage reinforcement area 33, a drainage area (or condensate confluence area) 16 and a drainage protection area 17. The wind guide area 31 mainly includes a wind guide portion 11, a water blowing prevention portion 12 and a second supporting portion 15, the wind and condensate water regulating area 32 mainly includes a reflecting portion 13, and the drainage reinforcement area 33 mainly includes a water collecting portion 14, and the angle between one end of the bottom surface of the water collecting cavity 141 adjacent to the water guiding slope of the water collecting portion 14 close to the reflecting portion 13 and the horizontal plane is 50°-80°, and the angle between one end of the bottom surface of the water collecting cavity 141 adjacent to the side wall of the water collecting portion 14 away from the reflecting portion 13 and the horizontal plane is 25°-55°, and the side walls on both sides of the water collecting portion 14 are inclined so as to guide the condensate water into the water collecting cavity 141 of the water collecting portion 14, and the bottom surface 147 of the water collecting cavity 141 is inclined downward in the direction from the water collecting portion 14 toward the drainage area 16, so that the condensate water in the water collecting cavity 141 flows to the drainage area 16.

[0115] By dividing the above five areas, the effects of uniform air flow and smooth drainage can be achieved. It should be understood that the water tray body 1 is not limited to the above areas.

[0117] The provision of the anti-overflow portion 18 can prevent the condensed water gathered on the first supporting surface 144 from overflowing from the side of the water collecting portion 14 away from the reflecting portion 13 .

[0120] Of course, the height t of the anti-overflow portion 18 is not limited to the above range and can be adjusted according to actual needs.
