[0002] The indoor unit of an air conditioner used to adjust the temperature and humidity in the user's room usually includes main structural components such as a heat exchanger and a fan. An air inlet and an air outlet are provided on the shell of the air conditioner indoor unit. Indoor air enters through the air inlet on the shell, completes heat exchange with the heat exchanger, and is blown out from the air outlet.

[0003] When the air conditioner is operating in cooling or dehumidification mode, condensation is likely to form on the heat exchanger. This condensation needs to be promptly drained through components such as the drain pan, water pipes, and water pumps, or evaporated by heating to prevent it from flowing directly into the user's room and affecting the user experience.

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0051] An embodiment of the present disclosure provides a heat exchanger including a first heat exchange module 41 and a second heat exchange module 42 .

[0052] The first heat exchange module 41 includes a first fin group and a first heat exchange tube group passing through the first fin group, and the fins in the first fin group include a first free end 411 and a first connecting end 412; the second heat exchange module 42 includes a second fin group and a second heat exchange tube group passing through the second fin group, and the fins in the second fin group include a second free end 421 and a second connecting end 422, and the second connecting end 422 is connected to the first connecting end 412, so that the first heat exchange module 41 and the second heat exchange module 42 are arranged at an angle. Among them, the fins in the second fin group include an upper fin section 423 and a lower fin section 424, and an arc-shaped connecting section is provided between the upper fin section 423 and the lower fin section 424. Figures 1 to 4 shown.

[0053] The first heat exchange module 41 and the second heat exchange module 42 of the heat exchanger are arranged at an angle, making the heat exchanger roughly V-shaped. As mentioned above, in a multi-stage heat exchanger structure, when condensed water flows along the surface of the heat exchanger, it is easy to drip from the surface before flowing to the water receiving pan. This phenomenon is particularly prone to condensed water dripping from the bends of the multi-stage heat exchanger.

[0054] In the heat exchanger provided in the embodiment of the present disclosure, the second heat exchange module 42 is a two-section type, including an upper wing section 423 and a lower wing section 424, and an arc-shaped connecting section is provided between the upper wing section 423 and the lower wing section 424. The setting of the arc-shaped connecting section replaces the existing angle connection setting. In this way, the surface of the second heat exchange module 42 is roughly semicircular, and the inner concave surface of the semicircle faces the first heat exchange module 41. The condensed water on the surface of the heat exchanger can flow more smoothly along the surface of the heat exchanger fins to the water receiving tray without slipping in the middle. In this way, the user experience is improved.

[0055] Optionally, the arc-shaped connecting section is integrally formed with the upper fin segment 423 and the lower fin segment 424. In this way, the number of welding points of the fins in the second fin group is reduced, and the fluidity of the condensed water along the fin surface is further improved.

[0056] Optionally, the inner concave surface of the arc-shaped connecting section faces the first heat exchange module 41 .

[0057] Optionally, the upper fin section 423 includes a first fin inner end facing the first heat exchange module 41 and a first fin outer end away from the first heat exchange module 41; the lower fin section 424 includes a second fin inner end facing the first heat exchange module 41 and a second fin outer end away from the first heat exchange module 41. A first arc-shaped connecting section 425 is provided between the first fin inner end and the second fin inner end. Figure 3 As shown, a second arc-shaped connecting section 426 is provided between the outer end of the first fin and the outer end of the second fin. Figure 4 shown.

[0058] A first arcuate connecting section 425 is provided between the inner ends of the first and second fins, and a second arcuate connecting section 426 is provided between the outer ends of the first and second fins. Thus, the inner and outer ends of the upper and lower fin sections 423 and 424 are both arcuate, improving the flow of condensed water along the fin surfaces. The inner end can be understood as the end facing toward or closer to the first heat exchange module 41, while the outer end can be understood as the end facing away from or away from the first heat exchange module 41.

[0059] Optionally, the first arc-shaped connecting section 425 and the second arc-shaped connecting section 426 are arranged at the same height of the heat exchanger. Figure 3 and Figure 4 shown.

[0060] Optionally, the first arc-shaped connecting section 425 faces the first heat exchange module 41 ; and / or the second arc-shaped connecting section 426 faces the first heat exchange module 41 .

[0061] The inner concave surface of the first arc-shaped connecting section 425 faces the first heat exchange module 41. Similarly, the inner concave surface of the second arc-shaped connecting section 426 also faces the first heat exchange module 41. In this way, the condensed water from the upper fin section 423 of the second heat exchange module 42 can smoothly flow downward along the first arc-shaped connecting section 425 and the second arc-shaped connecting section 426 to the water receiving pan.

[0062] Optionally, the length of the first arc-shaped connecting segment 425 is less than or equal to the length of the second arc-shaped connecting segment 426 ; and / or the curvature of the first arc-shaped connecting segment 425 is greater than or equal to the curvature of the second arc-shaped connecting segment 426 .

[0063] The first arcuate connecting section 425 is located at the inner end of the fin, and the second arcuate connecting section 426 is located at the outer end of the fin. The length of the first arcuate connecting section 425 can be relatively short, while the length of the second arcuate connecting section can be relatively long. Optionally, the first arcuate connecting section 425 has a relatively large curvature, while the second arcuate connecting section 426 has a relatively small curvature.

[0064] Optionally, the angle between the fins in the first fin group and the horizontal plane is greater than or equal to 45°; and / or, the angle between the fins in the second fin group and the horizontal plane is greater than or equal to 45°; and / or, the angle between the upper wing segment 423 and the horizontal plane is greater than the angle between the lower wing segment 424 and the horizontal plane.

[0065] like Figure 2 As shown, the angle between the fins in the first fin group and the horizontal plane is a1, and a1 ≥ 45°. In this way, the fluidity of the condensed water along the fins in the first fin group is improved, so that the condensed water generated by the first heat exchange module 41 flows smoothly to the water receiving tray. Similarly, the angle between the fins in the second fin group and the horizontal plane is a2, and a2 ≥ 45°. In this way, the fluidity of the condensed water along the fins in the second fin group is improved, so that the condensed water generated by the second heat exchange module 42 flows smoothly to the water receiving tray. Optionally, the angle between the upper fin segment 423 and the horizontal plane is greater than 50° and less than or equal to 90°.

[0066] Optionally, the heat exchanger further includes a side plate 43 and a support frame 44. The side plate 43 is disposed at the first end of the first heat exchange module 41 and the second heat exchange module 42; the support frame 44 is disposed at the second end of the first heat exchange module 41 and the second heat exchange module 42. The inner end surface 431 of the side plate 43 is arc-shaped, and the arc-shaped inner end surface 431 faces the first heat exchange module 41. Figure 1 shown.

[0067] The tails of the first and second heat exchange tube groups are supported by support frames 44, and the outlet sides are fixed by side plates 43, which improves the support effect on the heat exchanger. In the embodiment of the present disclosure, the inner end surface 431 of the side plate 43 is also curved.

[0068] The embodiment of the present disclosure also provides a TV cabinet air conditioner.

[0069] The TV cabinet air conditioner comprises a TV cabinet housing and a heat exchanger arranged in the housing. The heat exchanger is the heat exchanger as described above.

[0070] As people's living standards improve, they have increasingly higher requirements for the integration of home appliances and furniture. The disclosed embodiments provide a TV cabinet air conditioner with an indoor unit embedded within the TV cabinet, which effectively utilizes the user's indoor space while improving the integration of the air conditioner indoor unit and the TV cabinet.

[0071] The air outlet 32 ​​of the TV cabinet air conditioner is arranged on the upper part of the side panel, and the overall air outlet height is relatively low. In this way, when the air conditioner is in heating mode, the hot air is blown to the floor of the user's room, which is more conducive to the sinking of the hot air and improves the heating effect of the air conditioner.

[0072] Optionally, the TV cabinet housing further includes an air inlet 31 , and a filter is provided at the air inlet 31 to reduce dust or other debris from entering the housing of the air conditioner indoor unit.

[0073] Optionally, the TV cabinet air conditioner further includes a water receiving pan for receiving condensed water flowing down from the heat exchanger, the water receiving pan includes a first abutting groove 11, and a first water collecting trough 12 and a second water collecting trough 13 respectively provided at both ends of the first abutting groove 11, wherein the heat exchanger abuts against the first abutting groove 11, and the side wall of the first abutting groove 11 is stepped. Figure 5 and Figure 6 shown.

[0074] The connection between the first heat exchange module 41 and the second heat exchange module 42 of the heat exchanger abuts against the first abutment groove 11, and the first abutment groove 11 is stepped. The first heat exchange module 41 and the second heat exchange module 42 are arranged side by side in the first abutment groove 11. In this way, the condensed water generated by the first heat exchange module 41 and the second heat exchange module 42 can first flow into the first abutment groove 11, and then flow into the first water collection tank 12 or the second water collection tank 13, where it is collected.

[0075] Optionally, the first abutting groove 11 includes an abutting bottom wall at the bottom and a flared opening at the top, wherein the width of the abutting bottom wall is smaller than the width of the flared opening. Figure 5 As shown, the width of the abutting bottom wall of the first abutting groove 11 is h1, and the width of the flared opening is h2. In this way, the abutting bottom wall of the first abutting groove 11 can be set as narrow as possible, thereby ensuring the air inlet area at the air inlet, improving the air inlet volume and the heat exchange efficiency of the whole machine.

[0076] Optionally, the TV cabinet air conditioner further includes a water pump 14 disposed in the first sump 12. In this manner, the water pump 14 can drain condensed water collected in the first sump 12. Optionally, the height of the first sump 12 is lower than the height of the second sump 13 and the height of the first abutting groove 11. This allows the condensed water in the first abutting groove 11 and the second sump 13 to flow into the first sump 12 and be drained through the water pump 14.

[0077] Optionally, the embodiment of the present disclosure provides a double-layer water receiving tray assembly for receiving condensed water from a heat exchanger in a TV cabinet air conditioner. Figures 7 to 13 shown.

[0078] Optionally, the double-layer water receiving tray assembly includes a first water receiving portion 1 and a second water receiving portion 2. The first water receiving portion 1 includes a first water receiving trough portion and a first raised portion protruding from the first water receiving trough portion, the first raised portion being provided with a plurality of air holes 101; the second water receiving portion 2 is overlying the first raised portion, and a wind gap is provided between the second water receiving portion 2 and the plurality of air holes 101, so that air flowing in from the air holes 101 can flow out through the wind gap.

[0079] The first raised portion of the first water receiving portion 1 protrudes from the first water receiving trough portion, so that in the vertical height direction, the height of the first raised portion is higher than the height of the first water receiving trough portion. The first raised portion is provided with a plurality of air holes 101. Optionally, the air holes 101 pass through the first raised portion.

[0080] The second water receiving portion 2 is disposed above the first raised portion and is generally shaped to cover the first raised portion. Optionally, when projected vertically, a first projection of the second water receiving portion 2 covers a second projection of the first raised portion. Optionally, the second water receiving portion 2 can be used to securely connect the heat exchanger 4.

[0081] A wind gap is provided between the second water receiving portion 2 and the wind hole 101. It is understandable that the wind gap is connected to the wind hole 101. In this way, the wind passing through the wind hole 101 can continue to flow out through the wind gap.

[0082] A double-layer water receiving tray assembly is provided at the bottom of the heat exchanger 4. The shell is provided with an air inlet 31 and an air outlet 32, and the air inlet 31 is provided at the bottom shell, thus forming a bottom air intake mode. When the indoor air enters from the lower air inlet 31, it can flow through the air hole 101 of the first water receiving part 1 and flow through the wind gap to the heat exchanger 4 to exchange heat with the heat exchanger 4. Figure 13 As shown by the arrow in the flow direction. It can be seen that the double-layer water receiving tray assembly provided by the embodiment of the present disclosure does not block the air inlet when the air inlet 31 is set at the lower part of the TV cabinet shell, thereby ensuring the heat exchange capacity of the heat exchanger 4.

[0083] Optionally, the shape of the air hole 101 may be circular, polygonal or other irregular shapes. The embodiment of the present disclosure does not impose too many restrictions on the shape of the air hole 101.

[0084] Optionally, the inner diameter of the air hole 101 is less than or equal to 10 mm.

[0085] Optionally, a plurality of air holes 101 are evenly arranged along a preset straight line on the first raised portion, such as Figures 9 to 11 As shown; or, a plurality of air holes 101 are arranged in an array on the first raised portion.

[0086] Optionally, the first raised portion includes a platform portion 111 and a connecting plate portion. The connecting plate portion is connected between the platform portion 111 and the first water receiving trough portion. The air hole 101 is provided at one end of the connecting plate portion close to the platform portion 111.

[0087] Air hole 101 is located at one end of the connecting plate portion, near platform portion 111. That is, air hole 101 is positioned at a higher position on the connecting plate portion. This allows for a certain amount of condensed water to be absorbed by first water receiving portion 1 without obstructing or clogging air hole 101. Furthermore, the elevated position of air hole 101 increases the amount of water received by first water receiving portion 1, preventing condensed water from overflowing from air hole 101.

[0088] Optionally, the connecting plate portion includes a first connecting inclined plate 112 and a second connecting inclined plate 113 respectively connected to both sides of the platform portion 111. Figure 10 As shown. Moreover, the distance between the first connecting inclined plate 112 and the second connecting inclined plate 113 near one end of the first water receiving trough portion is a first distance H1, and the distance between the first connecting inclined plate 112 and the second connecting inclined plate 113 near one end of the platform portion 111 is a second distance H2, wherein the first distance H1 is greater than the second distance H2. Figure 11 shown.

[0089] In the disclosed embodiment, the first spacing H1 formed by the first connecting slanted plate 112 and the second connecting slanted plate 113 is greater than the second spacing H2, that is, the first raised portion is roughly in the shape of a boss that is wider at the bottom and narrower at the top. This increases the air intake at the first spacing H1, increases the heat exchange capacity of the heat exchanger 4, and thus improves the heat exchange capacity of the heat exchanger 4.

[0090] Optionally, the inclination angle of the first connecting inclined plate 112 is the same as the inclination angle of the second connecting inclined plate 113 .

[0091] Optionally, the first connecting inclined plate 112 is provided with a first row of air holes, the first row of air holes including a plurality of air holes 101, and the second connecting inclined plate 113 is provided with a second row of air holes, the second row of air holes including a plurality of air holes 101. The plurality of air holes 101 in the first row of air holes are arranged correspondingly to the plurality of air holes 101 in the second row of air holes. Optionally, the arrangement height of the air holes in the first row is equal to the arrangement height of the air holes in the second row.

[0092] Optionally, the first water receiving trough portion includes a main water receiving portion, a first water collecting trough 12 and a second water collecting trough 13, the first water collecting trough 12 is connected to the first end of the main water receiving portion, the second water collecting trough 13 is connected to the second end of the main water receiving portion, and the main water receiving portion includes a first water receiving bottom surface, the first water collecting trough 12 includes a first water collecting bottom surface, and the second water collecting trough 13 includes a second water collecting bottom surface, wherein the first water collecting bottom surface is lower than the first water receiving bottom surface; and / or the second water collecting bottom surface is lower than the first water receiving bottom surface. Figure 9 shown.

[0093] A first water collecting trough 12 and a second water collecting trough 13 are respectively provided at both ends of the main water receiving part. Moreover, the first water collecting bottom surface of the first water collecting trough 12 is lower than the first water receiving bottom surface, and the second water collecting bottom surface of the second water collecting trough 13 is lower than the first water receiving bottom surface. In this way, the condensed water flowing into the main water receiving part can flow to the first water collecting trough 12 or the second water collecting trough 13 under the action of gravity. The double-layer water receiving tray assembly provided in the embodiment of the present disclosure increases the amount of condensed water received while preventing the condensed water from blocking the air hole 101 and preventing the condensed water from overflowing from the air hole 101.

[0094] Optionally, the main water receiving portion is arranged along the length direction, and the first water collecting trough 12 and the second water collecting trough 13 are arranged along the width direction. The main water receiving portion, the first water collecting trough 12 and the second water collecting trough 13 roughly form an "I" shape.
