[0025] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] The embodiment of the present application provides a water receiving tray 100 to solve the technical problem of water accumulation under the evaporator in the prior art.

[0028] In the embodiments of the present application, Figure 1-Figure 3 As shown, the water receiving tray 100 includes a bottom plate 10, a side plate 20 and a supporting structure 30. The side plate 20 is arranged on the periphery of the bottom plate 10 to enclose the bottom plate 10 to form a water collection area 11; the supporting structure 30 includes a plurality of bosses 31 for supporting the heat exchanger 200. The plurality of bosses 31 are arranged on the bottom plate 10 at intervals. A drainage groove 32 is provided on the side of the boss 31 facing the heat exchanger 200. A drainage port 321 is provided on the side wall of the drainage groove 32. The drainage groove 32 is connected to the water collection area 11 through the drainage port 321.

[0029] It should be noted that the inventors analyzed and found that in the prior art, the bottom of the evaporator and the supporting part on the water receiving tray are mostly in surface contact. During the dripping process of condensed water, part of the condensed water sticks to the contact surface and cannot be drained away in time, resulting in water accumulation under the evaporator, increasing the wind resistance at the lower end of the evaporator.

[0030] To this end, the water receiving tray 100 provided in the present application is provided with a plurality of bosses 31 for supporting the heat exchanger 200 on the base plate 10. Since the plurality of bosses 31 are arranged at intervals, the contact area between the bosses 31 and the bottom of the heat exchanger 200 is reduced, thereby preventing a large amount of condensed water from adhering to the contact surface and not being discharged in time; and by providing a drainage groove 32 on the side of each boss 31 facing the heat exchanger 200, the contact area between the boss 31 and the bottom of the heat exchanger 200 is further reduced. Since there is a certain height difference between the evaporator fin and the bottom of the drainage groove 32, when the condensed water drops into the water receiving groove, it can be directly discharged into the water collection area 11 through the drainage port 321. The condensed water will not adhere to the surface of the boss 31, which is beneficial to prevent the condensed water from blocking the fin gap and causing the wind resistance to increase, thereby improving the heat exchange efficiency of the evaporator.

[0031] For details, please refer to Figure 1 The heat exchanger 200 can be an evaporator, which is vertically arranged above the water receiving tray 100. The lower end of the evaporator can be fixed to the side panel 20 by means of a snap connection or a screw connection. The support structure 30 is used to support the middle part of the evaporator close to the water receiving tray 100. On the one hand, it can reduce the contact area between the fins of the heat exchanger 200 and the water receiving tray 100, so that the water receiving tray 100 can discharge condensed water in time; on the other hand, it can prevent the fins of the heat exchanger 200 from being immersed in condensed water and affecting the heat exchange effect. In this embodiment, the evaporator can also be set to an arc shape. The arc-shaped evaporator can semi-surround the fan setting, which is beneficial to increase the heat exchange area of ​​the evaporator and improve the cooling capacity of the air conditioner.

[0032] See also Figure 2 and Figure 3 The bottom plate 10 can be arranged in a flat plate shape, and the plane where the bottom plate 10 is located has a certain inclination angle with the horizontal plane, and the inclination angle is usually greater than or equal to 3°, so as to ensure that the condensed water in the water collection area 11 can be completely discharged. The side plate 20 is arranged around the periphery of the bottom plate 10, and the side plate 20 and the bottom plate 10 are preferably formed in one piece, which can not only ensure the strength of the water receiving tray 100, but also prevent water leakage at the connection between the bottom plate 10 and the side plate 20.

[0033] The arrangement relationship of the plurality of bosses 31 on the bottom plate 10 is related to the shape of the heat exchanger 200. When the heat exchanger 200 is arc-shaped, the plurality of bosses 31 are arranged in an arc shape; when the heat exchanger 200 is straight, the plurality of bosses 31 are arranged in a straight line. In addition, the bosses 31 can be a solid structure or a hollow structure. Under the condition of ensuring the structural strength, the hollow bosses 31 can reduce the weight of the water receiving tray 100, reduce the material usage, and reduce the product cost.

[0034] When the air conditioner is in cooling mode, the condensed water generated by the evaporator drips along the direction of gravity, and most of the condensed water directly drips into the water collection area 11 of the water receiving tray 100. Among them, a small part of the condensed water drips along the fins into the drainage groove 32 of the boss 31, and then is discharged into the water collection area 11 through the drainage port 321. During this process, the condensed water will not adhere to the surface of the boss 31, which is beneficial to prevent the condensed water from blocking the fin gaps.

[0035] Optionally, in one embodiment, see Figure 2-Figure 5 A support rib 33 is provided on the edge of the boss 31 facing the heat exchanger 200 . The support rib 33 and the boss 31 are combined to form a drainage groove 32 . The bottom wall of the drainage groove 32 is inclined toward the side of the drainage port 321 .

[0036] It is understandable that in this embodiment, a circle of support ribs 33 can be provided on the periphery of the boss 31, that is, the support ribs 33 and the boss 31 facing the side of the heat exchanger 200 are enclosed to form a drainage groove 32, and then a drainage port 321 is provided on the support ribs 33 to drain the condensed water in the drainage groove 32. In this embodiment, by tilting the bottom wall of the drainage groove 32 toward the side of the drainage port 321, the drainage efficiency of the condensed water in the drainage groove 32 is improved, and the condensed water is prevented from accumulating at the bottom of the drainage groove 32.

[0037] In addition, in this embodiment, the boss 31 and the support rib 33 can be integrally injection molded to ensure the connection strength between the boss 31 and the support rib 33 , so that the support rib 33 has a better supporting effect on the heat exchanger 200 .

[0038] Optionally, in one embodiment, the boss 31 is recessed downward on one side of the heat exchanger 200 to form a drainage groove 32 , and the bottom wall of the drainage groove 32 is inclined toward one side of the drainage port 321 .

[0039] It is understandable that in this embodiment, there is no need to set up additional support ribs 33. The drainage groove 32 can be formed by only setting the side of the boss 31 facing the heat exchanger 200 downwardly concavely, and then opening a drainage port 321 on the side wall of the drainage groove 32 to drain the condensed water in the drainage groove 32. Since the bottom wall of the drainage groove 32 is inclined toward the side of the drainage port 321, the drainage efficiency of the condensed water in the drainage groove 32 is improved, and the condensed water is prevented from accumulating at the bottom of the drainage groove 32.

[0040] For further information, see Figure 3-Figure 5 , the angle formed by the bottom wall of the drainage groove 32 and the horizontal plane is α, where α≥3°; and / or, the distance between the highest point of the bottom wall of the drainage groove 32 and the top surface of the drainage groove 32 is H, where H≥5mm.

[0041] It can be understood that when the inclination angle of the bottom wall of the drain groove 32 is greater than or equal to 3°, the drainage effect of the drain groove 32 is better, and the condensed water in the drain groove 32 can be smoothly discharged to avoid the condensed water accumulating at the bottom of the drain groove 32; when the distance between the highest point of the bottom wall of the drain groove 32 and the top surface of the drain groove 32 is greater than 5 mm, the condensed water will not stick between the bottom of the heat exchanger 200 and the boss 31, which can not only prevent the condensed water from blocking the fin gaps, but also prevent the bottom of the evaporator from mold and odor.

[0042] Optionally, in one embodiment, see Figure 2 , Figure 3 and Figure 6 The water receiving tray 100 further includes a flow guiding structure 40 , and the flow guiding structure 40 and the plurality of bosses 31 are arranged in a maze-like manner in the water collecting area 11 .

[0043] Specifically, in this embodiment, the heat exchanger 200 can be supported only on the boss 31, or can be supported on the boss 31 and the guide structure 40 at the same time. The guide structure 40 can guide the condensed water dripping into the water collection area 11, so that the condensed water flows in a desired direction, so that the water receiving tray 100 can discharge the condensed water. Since the bottom of the heat exchanger 200 and the bottom of the guide structure 40 also have a certain height difference, the condensed water on the heat exchanger 200 will not adhere to the surface of the guide structure 40, ensuring that the condensed water can be quickly discharged.

[0044] The guide structure 40 and the multiple bosses 31 are arranged in a maze shape, which can ensure the supporting strength of the boss 31. Without affecting the drainage performance of the water receiving tray 100, it can reduce the contact area between the boss 31 and the guide structure 40 and the bottom of the heat exchanger 200, thereby preventing the condensed water on the heat exchanger 200 from sticking to the surface of the boss 31 and the guide structure 40.

[0045] For further information, see Figure 3 and Figure 6 The guide structure 40 includes a plurality of first guide ribs 41, a plurality of second guide ribs 42 and a plurality of third guide ribs 43; a first guide rib 41 is provided on each of the opposite sides of the boss 31, and the first guide rib 41 extends toward one side of the adjacent boss 31; the second guide rib 42 is correspondingly arranged between two adjacent bosses 31, so that a second guide rib 42 is configured between each of the two adjacent bosses 31; and the plurality of third guide ribs 43 are arranged at intervals along the circumference of the side plate 20.

[0046] In this embodiment, the first guide rib 41 and one side of the boss 31 can be set to be arc-shaped, and the first guide rib 41 is transitionally connected to the arc-shaped side surface of the boss 31, and there is a gap between the first guide ribs 41 on two adjacent bosses 31; the second guide rib 42 includes a main body and folded edges arranged on both sides of the main body, and the main body is correspondingly arranged at the gap, and the folded edges are respectively arranged at intervals between the corresponding bosses 31 to ensure that the condensed water at the first guide rib 41 can be discharged from between the folded edges and the boss 31; one side of the third guide rib 43 is connected to the side panel 20, and the other side is connected to the bottom plate 10, which not only increases the connection strength between the side panel 20 and the bottom plate 10, but also can guide the condensed water at the edge of the water receiving tray 100 to the gap between the two first guide ribs 41, ensuring that the condensed water can flow smoothly to the lowest point of the water receiving tray 100.

[0047] Optionally, in one embodiment, see Figure 2 and Figure 3 A drainage hole 12 for draining condensed water is provided on the bottom plate 10, and the periphery of the drainage hole 12 is arranged in a funnel shape.

[0048] It is understandable that the drain hole 12 is usually set at the lowest point of the water receiving tray 100, but because the bottom plate 10 is usually flat and inclined, the lowest point of the water receiving tray 100 is usually located at the edge of the bottom plate 10, which is not conducive to the drainage of the water receiving tray 100 as a whole. For this reason, in this embodiment, the periphery of the drain hole 12 is set to be funnel-shaped, that is, the plate surface of the periphery of the drain hole 12 has a certain inclination angle with the horizontal plane, and the inclination angle can be greater than or equal to 3°, so as to ensure that the condensed water in the water receiving tray 100 can be quickly discharged to the outside through the drain hole 12, thereby improving the drainage performance of the water receiving tray 100.

[0049] Optionally, in one embodiment, see Figure 6The top of the side plate 20 is provided with an overflow port 22, which penetrates the side plate 20 along the thickness direction of the side plate 20, and is arranged near the drain hole 12. It can be understood that when the drain hole 12 is abnormally blocked, since the overflow port 22 is arranged on the side plate 20, the condensed water can overflow out of the water receiving pan 100 according to the designed position, and will not randomly overflow from the water receiving pan 100 to the live parts, thereby avoiding electrical safety accidents caused by abnormal blocking of the drain hole 12 and improving the safety performance of the air conditioner.

[0050] For further information, see Figure 6 , the side plate 20 is recessed into the water collection area 11 to form an avoidance portion 21, the avoidance portion 21 is arranged close to the drain hole 12, and the overflow port 22 is arranged on the avoidance portion 21. It can be understood that when other parts are arranged at the overflow port 22 in the air conditioner, the overflow port 22 may not be able to drain normally. Therefore, in this embodiment, the overflow port 22 is arranged on the avoidance portion 21. Since the avoidance portion 21 is recessed into the water collection area 11, it is ensured that the condensed water can be discharged smoothly from the overflow port 22 after the drain hole 12 is abnormally blocked. Preferably, the distance that the avoidance portion 21 is recessed into the water collection area 11 is L, where L≥5mm. In this way, it can be ensured that the condensed water will not adhere between the avoidance portion 21 and other parts. In addition, the width of the overflow port 22 can also be greater than or equal to 5mm to ensure the overflow effect of the water receiving tray 100.

[0051] Optionally, in one embodiment, the water receiving tray 100 is an integrally formed structure. That is, in this embodiment, the side plate 20, the support structure 30 and the flow guide structure 40 are all integrally arranged on the bottom plate 10, so that the overall structural strength of the water receiving tray 100 is ensured, so that the support structure 30 can provide a good supporting effect on the heat exchanger 200, and at the same time, the production efficiency of the water receiving tray 100 is improved, and the manufacturing cost of the product is reduced.

[0052] The embodiment of the present application also provides an air conditioner, which includes a water receiving tray 100. The specific structure of the water receiving tray 100 refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
