[0002] In existing air conditioning heat exchangers, the airflow entering the heat exchanger is prone to backflow after colliding with the water collection tray. The backflowing airflow mixes with the incoming high-speed airflow to form a vortex, resulting in unstable and fluctuating airflow speed after passing through the water collection tray. Furthermore, the condensate generated on the heat exchanger is easily drawn into the vortex and cannot be accurately collected in the water collection tray. Utility Model Content

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0037] This application provides a water receiving tray to solve the problem that existing water receiving tray structures are prone to inducing eddies. The following description will be provided in conjunction with the accompanying drawings.

[0038] In the embodiments of this application, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the water receiving tray includes:

[0039] A first water inlet 1 and a second water inlet 2, inclined to each other, are used to collect condensate from the heat exchanger; and...

[0040] Support part 3 is connected between the first water receiving part 1 and the second water receiving part 2, and the support part 3 is provided with air guide channel 4;

[0041] The side wall of the air guide channel 4 is provided with a protruding air guide section, which is configured to extend in the direction close to the heat exchanger.

[0042] It should be noted that the angle formed between the first water receiving part 1 and the second water receiving part 2 is not equal to 0 degrees and not equal to 180 degrees. The water receiving tray has two water receiving positions: one is that the first water receiving part 1 is located below the heat exchanger to collect condensate, and the other is that the second water receiving part 2 is located below the heat exchanger to collect condensate.

[0043] Understandably, by forming an air guide channel 4 between the first water receiving part 1 and the second water receiving part 2 in the support part 3, the obstruction area of ​​the water receiving tray on the heat exchanger is reduced without affecting the water receiving function. This allows some airflow to flow directly to the heat exchanger through the air guide channel 4, reducing the probability of backflow after airflow collision and increasing the airflow rate into the heat exchanger. Simultaneously, based on the wall adhesion effect, the protruding air guide section guides as much of the airflow within the air guide channel 4 as possible to the heat exchanger, preventing the airflow from escaping from the outlet of the air guide channel 4, increasing the effective airflow rate into the heat exchanger, and ensuring that all condensate is collected in the water receiving tray. Furthermore, the protruding air guide section also strengthens the structural strength of the water receiving tray.

[0044] For example, the sidewall of the air guide channel 4 includes at least the surface of the first water receiving part 1, the surface of the second water receiving part 2, and the surface of the support part 3. Therefore, the air guide part can be provided on all three surfaces. Regarding the heat exchanger, the support part 3 and the second water receiving part 2 are located on the same side of the heat exchanger. Under different water receiving postures, the air guide channel 4 is located below the heat exchanger or on one side in the horizontal direction.

[0045] In some embodiments, such as Figure 3 As shown, the air guide section includes multiple air guide ribs 42, which are spaced apart on the same or different side walls of the air guide channel 4.

[0046] It should be noted that multiple air guide ribs 42 are protrudingly arranged on the side wall of the air guide channel 4.

[0047] Understandably, the air guide ribs 42, which are set at multiple intervals, can not only divide the airflow into multiple branches and reduce the chain reaction caused by the airflow hitting the wall, but also disperse the vortex formed, thereby more effectively guiding the airflow to the heat exchanger.

[0048] For example, the sidewall of the air guide channel 4 includes at least the surface of the first water receiving part 1, the surface of the second water receiving part 2, and the surface of the support part 3. Multiple air guide ribs 42 may be provided at intervals on one of the three surfaces, and multiple air guide ribs 42 may be provided at intervals on multiple of the three surfaces.

[0049] In some embodiments, such as Figure 3 As shown, the plurality of air guide ribs 42 include a first air guide rib 421 and a second air guide rib 422. The first air guide rib 421 is located in the first water receiving part 1, and the second air guide rib 422 is located in the second water receiving part 2.

[0050] It should be noted that multiple air guide ribs 42 are set in different positions, and are named and distinguished according to their positions. One or more first air guide ribs 421 are provided in the first water receiving part 1, and one or more second air guide ribs 422 are provided in the second water receiving part 2.

[0051] Understandably, airflow will sink under the action of gravity. By setting some of the air guide ribs 42 in the first water receiving part 1 and the second water receiving part 2, the first air guide rib 421 and the second air guide rib 422 can guide the sinking airflow to the heat exchanger when the water receiving pan is in different water receiving postures, and disperse the vortex generated after the sinking airflow hits the wall, further ensuring the air intake volume of the heat exchanger; at the same time, it strengthens the structural strength of the first water receiving part 1 and the second water receiving part 2.

[0052] In some embodiments, such as Figure 3 As shown, the plurality of air guide ribs 42 also include a third air guide rib 423, which is disposed on the support part 3.

[0053] It should be noted that, based on the first air guide rib 421 and the second air guide rib 422, some air guide ribs 42 are set in other positions and further named and distinguished according to their positions, namely the third air guide rib 423.

[0054] It is understandable that the third air guide rib 423 is used to guide the airflow over the surface of the support part 3 to the heat exchanger, thereby reducing airflow backflow and improving the airflow volume of the heat exchanger.

[0055] For example, the support part 3 includes a plurality of support arms 31 spaced apart, the plurality of support arms 31 being connected between the first water receiving part 1 and the second water receiving part 2, and the adjacent support arms 31, the first water receiving part 1 and the second water receiving part 2 forming an air guide channel 4. The third air guide rib 423 is protrudingly disposed on one or both sides of the support arm 31.

[0056] As another example, the first air guide rib 421, the second air guide rib 422, and the third air guide rib 423 may have the same or different shapes and sizes.

[0057] In some embodiments, such as Figure 4 As shown, at least one side wall of the air guide channel 4 is provided with an air guide surface 41, which is used to guide the airflow to the air guide channel 4, and at least one air guide rib 42 is provided along the air guide surface 41.

[0058] It should be noted that "the air guide surface 41 is used to guide the airflow to the air guide channel 4" excludes the case where the air guide surface 41 is perpendicular to the airflow direction, and the case where the air guide surface 41 guides the airflow to the side away from the air passage.

[0059] It is understandable that by setting an air guide surface 41 on the side wall of the air guide channel 4, the airflow is guided to flow into the air guide channel 4 and then into the heat exchanger. Compared with setting the side wall of the air guide channel 4 as a plane, the probability of backflow after the airflow hits the wall is reduced, thereby avoiding the backflow airflow from forming a turbine with the incoming high-speed airflow, reducing noise, and improving the effective airflow of the heat exchanger.

[0060] For example, the angle between the air guide surface 41 and the air intake direction of the air guide channel 4 is not equal to 90 degrees.

[0061] In another example, the sidewall of the air guide channel 4 includes at least the surface of the first water receiving part 1, the surface of the second water receiving part 2, and the surface of the support arm 31. One or more of the above three surfaces may be provided with a plurality of air guide ribs 42. Specifically, the sidewall of the air guide channel 4 has the following three configurations: at least one sidewall is provided with an air guide surface 41 and air guide ribs 42 located on the air guide surface 41; at least one sidewall is provided with an air guide surface 41; and at least one sidewall is provided with air guide ribs 42.

[0062] In some embodiments, such as Figure 4 As shown, multiple side walls of the air guide channel 4 are provided with air guide surfaces 41. The multiple air guide surfaces 41 are a first air guide surface 411 and a second air guide surface 412. The first air guide surface 411 is located in the first water receiving part 1, and the second air guide surface 412 is located in the second water receiving part 2.

[0063] It should be noted that the air guide surface 41 is set in different positions, and the multiple air guide surfaces 41 are named and distinguished according to their positions.

[0064] Understandably, airflow will sink under the action of gravity. Both the first water receiving part 1 and the second water receiving part 2 are provided with air guide surfaces 41. When the water receiving pan is in different water receiving postures, the first air guide surface 411 and the second air guide surface 412 can guide the sinking airflow to the heat exchanger, reduce airflow backflow and the corresponding eddies, and further ensure the airflow of the heat exchanger.

[0065] For example, the first air guide surface 411 is provided with a plurality of first air guide ribs 421, and the second air guide surface 412 is provided with a plurality of second air guide ribs 422. Along the air inlet direction of the air guide channel 4, the thickness of the first air guide ribs 421 and the second air guide ribs 422 gradually increases.

[0066] In some embodiments, such as Figure 5 As shown, the angles between the tangents at at least two arbitrary positions of the air guide surface 41 and the air inlet direction of the air guide channel 4 are not the same, and none of them are equal to 90 degrees.

[0067] It should be noted that, according to the limitations of this embodiment, the air guide surface 41 includes at least two inclined planes, or the air guide surface 41 is an arc surface, or the air guide surface 41 includes interconnected planes and arc surfaces.

[0068] It is understandable that by using surfaces with different tilt angles to change the direction of airflow and guide it to the air guide channel 4 and then to the heat exchanger, the airflow is made to avoid direct contact with the water receiving pan as much as possible, so as to reduce the corresponding noise.

[0069] For example, the air guide surface 41 covers at least the side of the first water receiving part 1 away from the heat exchanger and close to the air passage, i.e., the first air guide surface 411. The first air guide surface 411 can be one or more of a plane or an arc surface, such as multiple inclined planes, or a combination of planes and arc surfaces, or a single arc surface. The arc surface should bulge outward.

[0070] Specifically, the first air guide surface 411 includes an arc surface and a plane arranged sequentially along the air inlet direction of the air guide channel 4, with the extended surface of the plane intersecting the heat exchanger. The arc surface guides the airflow towards the plane, and the inclination direction of the plane causes the airflow to flow away from the first water receiving part 1 and then towards the heat exchanger. The extended surface of the plane intersects the heat exchange surface of the heat exchanger as close as possible to the middle of the heat exchange surface to ensure a large airflow and high velocity at all heat exchange surfaces of the heat exchanger, thereby improving heat exchange efficiency.

[0071] It should be noted that the extended surface of the plane included in the first air guide surface 411 refers to a virtual plane obtained by extending the aforementioned plane as a reference plane, and is not a solid structure.

[0072] Another example is that the air guide surface 41 at least covers the part of the second water receiving part 2 that is away from the heat exchanger and close to the air passage, namely the second air guide surface 412. The second air guide surface 412 can be one or more of a plane or an arc surface, such as multiple inclined planes, or a combination of planes and arc surfaces, or a single arc surface. The arc surface should bulge outward.

[0073] In some embodiments, such as Figure 2 As shown, at least part of the cross-section of the second water receiving part 2 is arc-shaped, and the side of the second water receiving part 2 away from the heat exchanger is set as an air guide surface 41.

[0074] It should be noted that the cross-section of the second water receiving part 2 refers to the cross-section obtained by cutting the second water receiving part 2 along its width direction, and a portion of the resulting cross-section is arc-shaped. That is, a portion of the surface of the second water receiving part 2 facing the heat exchanger and the surface away from the heat exchanger is arc-shaped. The side of the second water receiving part 2 away from the heat exchanger is set as the air guide surface 41, which is the second air guide surface 412.

[0075] It is understandable that by setting the second water receiving part 2 of the above structure, the condensate collection space and the second air guide surface 412 are manufactured in one go. Furthermore, the second air guide surface 412 can completely cover the entire windward side of the second water receiving part 2, and the airflow can flow to the heat exchanger through the air guide channel 4 or through the side of the air guide surface 41 away from the first water receiving part 1.

[0076] In some embodiments, such as Figure 2 As shown, the second water receiving part 2 is provided with a second water receiving trough 21. The trough wall of the second water receiving trough 21 is provided with a plurality of guide ribs 22 protrudingly. The guide ribs 22 are used to guide the condensed water to the bottom of the second water receiving trough 21.

[0077] It should be noted that, according to other embodiments, the surface of the second water receiving part 2 facing the heat exchanger is an arc surface, that is, the wall of the second water receiving tank 21 is an arc surface.

[0078] Understandably, when the second water receiving part 2 is located below the heat exchanger, the shape of the second water receiving trough 21 facilitates the collection of condensate at the bottom of the second water receiving trough 21. At the same time, the guide ribs 22 can quickly guide water while strengthening the structural strength of the second water receiving part 2.

[0079] For example, multiple guide ribs 22 are spaced apart along the length of the second water receiving tank 21 and are relatively spaced apart along the width of the second water receiving tank 21. Any two opposing guide ribs 22 are spaced apart at their ends near the bottom of the second water receiving tank 21 to facilitate the rapid drainage of condensate. The thickness of the guide ribs 22 gradually decreases near the bottom of the second water receiving tank 21.

[0080] In some embodiments, such as Figure 1 As shown, the water receiving tray also includes a guide section 5 connecting the first water receiving part 1 and the second water receiving part 2. The guide section 5 is provided with a guide groove 51. The first water receiving part 1 is provided with a first water receiving trough 11. The guide groove 51 connects the first water receiving trough 11 and the second water receiving trough 21. The first water receiving part 1 is provided with a plurality of drain holes 12, which are located close to the guide groove 51.

[0081] Understandably, when the first water receiving part 1 is located below the heat exchanger, the condensate from the heat exchanger is mainly collected through the first water receiving tank 11 and discharged from multiple drain holes 12. The multiple drain holes 12 can quickly drain away the condensate and prevent leakage. When the second water receiving part 2 is located below the heat exchanger, the condensate is guided to the drain holes 12 by the guide channel 51 and discharged away.

[0082] In some embodiments, such as Figure 1 As shown, there are two guide sections 5 along the length of the second water receiving tank 21. The two guide sections 5 are located at both ends of the support section 3, and the drain holes 12 are provided in a one-to-one correspondence with the guide sections 5.

[0083] It should be noted that there are two drain holes 12 to correspond to the two guide sections 5.

[0084] Understandably, the condensate collected in the second water receiving tank 21 flows to both ends of the second water receiving tank 21, and then flows out from the drain hole 12 through the guide channel 51. Furthermore, the two guide sections 5 can be set at both ends along the length of the heat exchanger to reduce the contact between the airflow and the guide sections 5 and avoid interfering with the airflow to the heat exchanger.

[0085] For example, the drain hole 12 is located at one end near the guide groove 51. When the first water receiving part 1 or the second water receiving part 2 is located below the heat exchanger, the water can flow out spontaneously from the drain hole 12, reducing the amount of condensate residue.

[0086] Furthermore, the two guide sections 5 are respectively spaced apart from the support arms 31 located at the two ends, thereby forming an air guide channel 4 with the first water receiving section 1 and the second water receiving section 2.

[0087] This application also provides an indoor air conditioning unit, which includes the aforementioned water collection tray. The specific structure of the water collection tray is as described in the above embodiments. Since this indoor air conditioning unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The heat exchanger includes at least one heat exchange section, which is inclined about the first water collection part 1 and the second water collection part 2. One side of the heat exchange section faces the first water collection part 1, and one end of the heat exchange section faces the second water collection part 2.

[0088] It should be noted that because the drip tray has two drip-collecting orientations, the air conditioner indoor unit has two installation methods: floor-mounted and ceiling-mounted. In floor-mounted installation, the air outlet of the indoor unit faces upwards, and the second drip-collecting part 2 is located below the heat exchanger. In ceiling-mounted installation, the air outlet of the indoor unit faces horizontally, and the first drip-collecting part 1 is located below the heat exchanger. Therefore, the air conditioner indoor unit in this application is a floor-mounted or ceiling-mounted indoor unit.

[0089] Understandably, when the second water receiving part 2 is located below the heat exchanger, the condensate flows along the surface of the heat exchange section to the lower end of the heat exchange section and drips into the second water receiving tank 21.

[0090] In some embodiments, the heat exchanger includes two inclined heat exchange sections, each heat exchange section including a plurality of parallel fins and a heat exchange tube, the plurality of fins being arranged side by side and spaced apart, the heat exchange tube passing through the plurality of fins, and the heat exchange tube being used for refrigerant to flow through; the plurality of fins in each heat exchange section are arranged side by side in the same direction.

[0091] It should be noted that the two inclined heat exchange sections refer to the two heat exchange sections being projected along the direction of the multiple fin arrangement, with the included angle between the two projections being greater than 0 degrees and less than or equal to 90 degrees.

[0092] It is understood that one heat exchange section is located between the first water receiving part 1 and the other heat exchange section, with one side of the two heat exchange sections touching each other and facing the second water receiving part 2. The water receiving tray provided in this application can be applied to an air conditioning indoor unit with two heat exchange sections. The second water receiving part 2, with an arc-shaped cross-section, can simultaneously guide airflow to both heat exchange sections, thereby enabling the air conditioning indoor unit to have better heat exchange efficiency.

[0093] This application also provides an air conditioner, which includes the above-mentioned indoor unit and outdoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
