[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] Embodiment 1 of the present invention provides a heat exchanger assembly, which is arranged in an indoor unit housing 40 of an air conditioner indoor unit. The heat exchanger assembly includes: a first heat exchanger 10 and a second heat exchanger 20. The second heat exchanger 20 is connected to the first heat exchanger 10, and the first heat exchanger 10 and the second heat exchanger 20 are connected to form an L-shaped structure. The end surface of the second heat exchanger 20 is in contact with the heat exchange surface of the first heat exchanger 10.

[0038] By using the heat exchanger assembly provided by the embodiment of the present invention, the first heat exchanger 10 and the second heat exchanger 20 are connected to form an L-shaped heat exchanger assembly, so that the connection ends of the first heat exchanger 10 and the second heat exchanger 20 are regular structures. Special-shaped cutting is avoided at the connection ends of the first heat exchanger 10 and the second heat exchanger 20. At the same time, since the end face of the second heat exchanger 20 fits the heat exchange surface of the first heat exchanger 10, there is no need to stick a sealing strip at the connection between the first heat exchanger 10 and the second heat exchanger 20 for sealing. Such a setting can facilitate processing and production, and there is no need to stick a sealing strip at the connection, which reduces the processing steps, improves processing efficiency, and reduces production costs. Therefore, the heat exchanger assembly provided by the present invention can solve the technical problem that the heat exchanger assembly in the prior art is not easy to produce and process.

[0039] In this embodiment, the angle between the first heat exchanger 10 and the second heat exchanger 20 is greater than 90 degrees or less than 90 degrees. With such a configuration, it is convenient to drain the water on the surface of the heat exchanger to the water receiving pan 50 in the indoor unit of the air conditioner. Preferably, the angle between the first heat exchanger 10 and the second heat exchanger 20 can be slightly greater than 90 degrees or slightly less than 90 degrees to facilitate the flow of condensed water.

[0040] Embodiment 2 of the present invention provides a heat exchanger assembly, which includes the first heat exchanger 10 and the second heat exchanger 20 in Embodiment 1, and the heat exchanger assembly also includes a third heat exchanger. The third heat exchanger is connected to the second heat exchanger 20, and the third heat exchanger is arranged opposite to the first heat exchanger 10. The heat exchanger assembly in this embodiment is a U-shaped structure, and the connecting end of the first heat exchanger 10, the connecting end of the second heat exchanger 20, and the connecting end of the third heat exchanger are all regular structures, so that special-shaped cutting can be avoided, the processing difficulty is reduced, the processing efficiency is improved, and the production cost is reduced.

[0041] In order to conveniently install the heat exchanger assembly in the first and second embodiments in the indoor unit housing 40, according to actual conditions, a connector 30 may be provided on the first heat exchanger 10; or a connector 30 may be provided on the second heat exchanger 20; or a connector 30 may be provided on both the first heat exchanger 10 and the second heat exchanger 20. Preferably, in the first and second embodiments, a connector 30 is provided on both the first heat exchanger 10 and the second heat exchanger 20, and the heat exchanger assembly in the first and second embodiments is connected to the indoor unit housing 40 through the connector 30.

[0042] Specifically, in order to facilitate the connection between the first heat exchanger 10 and the second heat exchanger 20, the first heat exchanger 10 and the second heat exchanger 20 can be connected by a connecting plate. Since the connecting end of the first heat exchanger 10 and the connecting end of the second heat exchanger 20 in this embodiment do not need to be cut into a special shape, it can avoid the first heat exchanger 10 and the second heat exchanger 20 from having a gap when overlapping, and there is no need to use a sealing strip, which facilitates production and processing, improves processing and installation efficiency, and reduces production costs.

[0043] In order to facilitate the connection, according to the actual situation, the connector 30 can be set at the end of the first heat exchanger 10; or the connector 30 can be set at the end of the second heat exchanger 20; or the connector 30 can be set at both the end of the first heat exchanger and the end of the second heat exchanger 20. Specifically, in the first embodiment and the second embodiment, the connector 30 is set at both the end of the first heat exchanger 10 and the end of the second heat exchanger 20, so as to facilitate the heat exchanger assembly to be set on the indoor unit housing 40. Specifically, the connector 30 can be relatively set at both ends of the first heat exchanger 10 and the two ends of the second heat exchanger 20, so that the heat exchanger assembly can be conveniently set on the indoor unit housing 40, and the stability of the assembly is improved. In the second embodiment, preferably, the connector 30 can also be set at the end of the third heat exchanger. Specifically, the connector 30 can be a connecting block.

[0044] Specifically, a connection hole is provided on the connection member 30, and the air conditioner indoor unit further includes a fastener, which is inserted into the connection hole of the connection member 30 to fix the heat exchanger assembly on the indoor unit housing 40. Such a setting can facilitate the operation of the operator, so that the operator can install the heat exchanger assembly on the indoor unit housing 40.

[0045] like Figures 1 to 12 As shown, the third embodiment of the present invention provides an air-conditioning indoor unit, which includes: an indoor unit housing 40 and a heat exchanger assembly. The indoor unit housing 40 has an air inlet. The heat exchanger assembly is the heat exchanger assembly in the first and second embodiments, and the heat exchanger assembly is arranged at the air inlet to exchange heat with the air entering the indoor unit housing 40. Since the end face of the second heat exchanger 20 is in contact with the heat exchange surface of the first heat exchanger 10, there is no gap at the connection between the first heat exchanger 10 and the second heat exchanger 20. Therefore, there is no need to set a seal at the connection between the first heat exchanger 10 and the second heat exchanger 20 for sealing, thereby reducing the processing steps of the heat exchanger assembly. When using the air-conditioning indoor unit, the air entering from the air inlet will be fully heat exchanged, which is beneficial to improve the heat exchange effect, thereby improving the indoor comfort.

[0046] Specifically, the air inlet may be provided with air inlet micropores, or the air inlet may be provided with a grille, and the indoor air enters the interior of the indoor unit housing 40 through the air inlet micropores or grille on the air inlet. The indoor unit of the air conditioner in this embodiment includes an air duct module, wherein the air duct module is relatively arranged on both sides of the indoor unit housing 40, the air duct module includes an air duct housing and a fan blade 90, an air inlet and an air outlet 80 are arranged on the air duct housing, and the air duct housing also has a receiving cavity connected to both the air inlet and the air outlet 80, and the fan blade 90 is arranged in the receiving cavity. The air in the indoor unit housing 40 enters the air duct module from the air inlet, and is discharged into the room through the air outlet 80 under the action of the fan blade 90. Specifically, in this embodiment, there are two air outlets 80, and the two air outlets 80 are relatively arranged at the two ends of the indoor unit housing 40.

[0047] By adopting such a layout of the indoor unit of the air conditioner, the heat exchanger assembly in this embodiment does not need to be fixed by an angle bracket, which improves the processing and installation efficiency and reduces the production cost. In this embodiment, it is only necessary to fix and cooperate the connecting piece 30 provided on the first heat exchanger 10, the second heat exchanger 20, and the third heat exchanger with the screw column on the bottom plate 44 and the water receiving tray 50, which is convenient and efficient to operate.

[0048] like Figures 4 to 8 As shown, the indoor unit housing 40 also includes a wall-mounted surface 41, which specifically refers to the mounting surface of the air-conditioning wall-mounted plate and the wall, and the air-conditioning indoor unit is installed on the wall through the wall-mounted surface 41. The air inlet portion includes a first air inlet surface 42 and a second air inlet surface 43, the first air inlet surface 42 is connected to one end of the second air inlet surface 43, and the wall-mounted surface 41 is connected to the other end of the second air inlet surface 43. The first heat exchanger 10 of the heat exchanger assembly is arranged opposite to the first air inlet surface 42, and the second heat exchanger 20 of the heat exchanger assembly is arranged opposite to the second air inlet surface 43 to perform heat exchange on the air entering the indoor unit housing 40. With such an arrangement, it is convenient for the heat exchanger assembly to perform heat exchange on the air in the indoor unit air conditioner, so as to improve the heat exchange effect and thus enhance the indoor comfort experience. When the heat exchanger assembly in the second embodiment is used in this embodiment, the third heat exchanger is arranged opposite to the wall-mounted surface 41.

[0049] In this embodiment, the angle between the first heat exchanger 10 and the second heat exchanger 20 is greater than 90 degrees or less than 90 degrees, and the first heat exchanger 10 of the heat exchanger assembly is vertically arranged so that the water on the surface of the second heat exchanger 20 of the heat exchanger assembly flows into the indoor unit casing 40. With such an arrangement, the second heat exchanger 20 is placed in a non-horizontal manner, which facilitates the flow of condensed water on the surface of the first heat exchanger 10.

[0050] In this embodiment, the indoor unit housing 40 further includes a bottom plate 44, which is connected to the wall-mounted surface 41 and is arranged opposite to the second air inlet surface 43. The bottom plate 44 is located at the bottom of the indoor unit housing 40. The air conditioner indoor unit further includes a water receiving pan 50, which is arranged in the indoor unit housing 40. The water receiving pan 50 is located below the heat exchanger assembly to collect condensed water on the surface of the heat exchanger assembly. With such an arrangement, the condensed water on the surface of the heat exchanger assembly can be conveniently collected by the water receiving pan 50.

[0051] In order to better collect the condensed water on the surface of the condenser assembly, the air conditioner indoor unit in this embodiment further includes a water receiving member 60, which is arranged at the bottom of the first heat exchanger 10 of the heat exchanger assembly, and the water receiving member 60 is connected to the water receiving pan 50, so that the condensed water collected in the water receiving member 60 flows into the water receiving pan 50. Specifically, the water receiving member 60 in this embodiment has a receiving groove, and the bottom of the first heat exchanger 10 is placed in the receiving groove of the water receiving member 60, so as to better collect the condensed water flowing down the surface of the first heat exchanger 10. A plurality of partitions are also arranged in the receiving groove of the water receiving member 60 at intervals, and the bottom of the first heat exchanger 10 can be abutted against the partition, so that on the one hand, the heat exchanger assembly can be stably arranged on the indoor unit housing 40 to improve stability, and on the other hand, the condensed water on the surface of the first heat exchanger 10 can be conveniently introduced into the receiving groove of the water receiving member 60. Specifically, the partition can be arranged parallel to the groove edge of the receiving groove.

[0052] In order to facilitate the introduction of water in the water receiving member 60 into the water receiving pan 50, the air conditioner indoor unit in this embodiment further includes a water receiving groove 70. The water receiving groove 70 is arranged between the water receiving member 60 and the water receiving pan 50, so that the condensed water collected by the water receiving member 60 flows through the water receiving groove 70 and then enters the water receiving pan 50.

[0053] like Figure 1 As shown, the water receiving chamber of the water receiving groove 70 in this embodiment has a tapered section, and the water in the water receiving member 60 flows through the tapered section of the water receiving groove 70 and enters the water receiving tray 50. With such a configuration, the water in the water receiving member 60 flows through the tapered section and the speed will increase, so as to flow into the water receiving tray 50 better.

[0054] Specifically, along the water flow direction in the tapered section, the flow area of ​​the tapered section gradually decreases, so that the water in the tapered section flows into the water receiving tray 50 more quickly to better collect the condensed water.

[0055] In this embodiment, the indoor unit housing 40 includes a side plate 45, which is arranged between the air inlet and the bottom plate 44, and the water receiving trough 70 is surrounded by the side plate 45 and the end plate connected to the side plate 45. With such an arrangement, the layout inside the air conditioner indoor unit can be more reasonable, and the internal structure can be more compact. Preferably, the water receiving member 60, the water receiving trough 70, the side plate 45 and the water receiving tray 50 can be arranged as an integrated structure, and such an arrangement can facilitate overall installation. At the same time, a drainage hole 100 can be arranged on the side plate 45, so that the water in the water receiving tray 50 can be discharged from the drainage hole 100.

[0056] In this embodiment, the water receiving pan 50 is connected to the side plate 45 and the wall surface 41, and the length of the water receiving pan 50 is greater than the length of the heat exchanger assembly. With such a configuration, the water receiving pan 50 can better collect condensed water on the surface of the heat exchanger assembly. Specifically, the length direction of the water receiving pan 50 is the same as the length direction of the heat exchanger assembly, and both directions extend from one air outlet 80 to the other air outlet 80.

[0057] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: avoiding special-shaped cutting at the connecting ends of the first heat exchanger 10, the second heat exchanger 20 and the third heat exchanger, improving the processing efficiency of the heat exchanger assembly, and reducing the production cost of the heat exchanger assembly.
