[0043] Figure 1FIG. 1 is a schematic structural diagram of a partial structure of an air-conditioning indoor unit according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 5 The embodiment of the present invention provides an air conditioner indoor unit. The air conditioner indoor unit includes an air duct frame 100 and a heat exchanger 200.

[0044] The air duct frame 100 includes an air duct plate 110. The air duct plate 110 is vertically arranged on one side of the air duct of the air conditioner indoor unit.

[0045] The heat exchanger 200 includes a tube sheet 210 , which is fixedly connected to one lateral end of the air duct plate 110 .

[0046] A plurality of vertically spaced ribs 300 are fixedly connected to the side of the air duct plate 110 away from the air duct. In the horizontal direction, the ribs 300 are spaced and adjacent to the tube plate 210, and one end of the rib 300 close to the tube plate 210 is higher than the other end.

[0047] In this embodiment, the duct frame 100 is directly connected to the heat exchanger 200. During air conditioner operation, the temperature of the heat exchanger 200 differs from the room temperature. Direct contact between the duct frame 100 and the heat exchanger 200 generates heat exchange, which easily leads to the formation of condensed water on the duct frame 100. The raised ribs 300, arranged obliquely toward the lower side away from the heat exchanger 200, guide the condensed water to the side away from the heat exchanger 200, preventing the condensed water formed on the duct frame 100 from accumulating on the heat exchanger 200. This, in turn, prevents the heat exchanger 200 from malfunctioning due to excessive condensed water on the heat exchanger 200, thereby extending the service life of the air conditioner indoor unit.

[0048] Over long-term use, the duct support 100 is susceptible to deformation due to factors such as internal and external pressure and temperature changes, which can lead to air leakage between the duct support 100 and the heat exchanger 200. The raised ribs 300, designed on the side of the duct plate 110 near the tube sheet 210, strengthen the structural strength of the duct support 100, preventing the air duct from deforming and improving the sealing effect between the duct support 100 and the heat exchanger 200.

[0049] To ensure the seal between the duct frame 100 and the heat exchanger 200 and ensure the stability of the connection, some existing air conditioner indoor units use a large number of sealing sheet metal parts. The use of sealing sheet metal parts not only increases the manufacturing cost of the air conditioner indoor unit but can also reduce the sealing effect due to improper installation or long-term use. The air duct plate 110 with raised ribs 300 replaces some of the functions of the sealing sheet metal parts to a certain extent, thereby reducing the number of sealing sheet metal parts used, lowering the cost of the air conditioner indoor unit, and simplifying the maintenance and service of the air conditioner indoor unit.

[0050] In some embodiments of the present invention, Figure 1 As shown, the air duct plate 110 is located on a lateral side of the air outlet 600 of the air conditioner indoor unit.

[0051] In the horizontal direction, the raised rib 300 and the air outlet 600 are spaced apart.

[0052] In this embodiment, there is a certain distance between the raised rib 300 and the air outlet 600 to prevent the condensed water from flowing or splashing to the air outlet 600 during the flow process, causing the condensed water to be blown out from the air outlet 600 along with the heat exchange air.

[0053] In some embodiments of the present invention, the length of the raised rib 300 is between 30 mm and 80 mm.

[0054] In this embodiment, if the length of the raised rib 300 is too short, the rib 300 has a poor drainage effect on the condensed water, which is not conducive to the raised rib 300 directing the condensed water to the side away from the heat exchanger 200. The raised rib 300 with a length that is too short also cannot provide sufficient support to ensure the strength of the air duct plate 110. If the length of the raised rib 300 is too long, the difficulty of forming the raised rib 300 and the manufacturing cost are increased.

[0055] The length of the raised rib 300 is between 30 mm and 80 mm, which takes into account the effect of guiding condensed water and the structural strength of the air duct plate 110, and also makes the molding difficulty of the raised rib 300 simpler, thereby reducing the manufacturing cost of the air conditioner indoor unit.

[0056] In some embodiments of the present invention, the angle between the raised rib 300 and the horizontal direction is between 10° and 45°.

[0057] In this embodiment, there is an angle between the raised rib 300 and the horizontal plane, so that under the action of gravity, the condensed water can flow along the raised rib 300 to the end away from the heat exchanger 200, and then the condensed water flows along the air duct plate 110 to the lower side of the air duct frame 100.

[0058] The larger the angle between the raised rib 300 and the horizontal plane, the greater the flow rate of the condensed water. However, when the horizontal distance between the end of the raised rib 300 away from the heat exchanger 200 is constant, the larger the angle between the raised rib 300 and the horizontal plane, the longer the required length of the raised rib 300, making the manufacturing of the raised rib 300 more difficult.

[0059] When the angle between the raised rib 300 and the horizontal plane is between 10° and 45°, it can ensure that the condensed water flows along the raised rib 300 at a faster speed, and can also avoid the manufacturing inconvenience caused by the excessive length of the raised rib 300.

[0060] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, a water receiving tray 400 is provided at the bottom of the air duct frame 100 .

[0061] The projection of the raised rib 300 in the vertical direction is located inside the water receiving tray 400 .

[0062] In this embodiment, a water collection pan 400 is provided at the bottom of the duct frame 100 to collect and store condensed water dripping from components such as the heat exchanger 200 or the duct frame 100. The vertical projection of the raised ribs 300 is located within the water collection pan 400, ensuring that the raised ribs 300 effectively guide the condensed water into the water collection pan 400.

[0063] In some embodiments of the present invention, Figure 4 As shown, a sealing structure 500 is provided between the air duct plate 110 and the tube plate 210 .

[0064] In this embodiment, the design of the sealing structure 500 further improves the sealing performance between the duct frame 100 and the heat exchanger 200, reduces the occurrence of air leakage between the duct frame 100 and the heat exchanger 200, thereby improving the heat exchange efficiency of the air conditioner indoor unit, and further improving the overall quality of the air conditioner.

[0065] In some embodiments of the present invention, the sealing structure 500 is a strip of rubber.

[0066] In some embodiments of the present invention, Figure 4 As shown, a first flange 111 extends from the edge of the air duct plate 110 close to the tube plate 210 toward the raised rib 300 , and a second flange 112 extends from one end of the first flange 111 away from the air duct plate 110 toward the tube plate 210 .

[0067] The sealing structure 500 is fixedly connected to one end of the tube plate 210 close to the air duct plate 110. The first flange 111 and the second flange 112 are both interference-connected to the sealing structure 500.

[0068] In this embodiment, the sealing structure 500 is disposed between the duct plate 110 and the tube sheet 210 to improve the sealing performance between the duct frame 100 and the heat exchanger 200. The first flange 111 and the second flange 112 semi-enclose the outer periphery of the sealing structure 500, thereby ensuring a more stable connection of the sealing structure 500. The first flange 111 and the second flange 112 form an interference fit with the sealing structure 500, ensuring that there is no gap between the duct plate 110 and the sealing structure 500, further improving the sealing performance between the duct frame 100 and the heat exchanger 200.

[0069] In some embodiments of the present invention, Figure 2 As shown, at least one first fixing seat 113 extending away from the air duct is fixedly connected to the air duct plate 110, and a first connection hole is formed in the first fixing seat 113. A second fixing seat 211 corresponding to the first fixing seat 113 is fixedly connected to the tube plate 210, and a second connection hole is formed in the second fixing seat 211. The first connection hole is aligned with the second connection hole.

[0070] In this embodiment, a first connecting hole is formed on the first fixing seat 113, and a second connecting hole aligned with the first connecting hole is formed on the second fixing seat 211, so that the first fixing seat 113 and the second fixing seat 211 are fixedly connected by fasteners, thereby making the connection between the duct frame 100 and the heat exchanger 200 more secure and improving the sealing performance between the duct frame 100 and the heat exchanger 200.

[0071] In some embodiments of the present invention, the first fixing seat 113 is disposed at the middle of the air duct plate 110 in the vertical direction.

[0072] In this embodiment, the middle portion of the air duct plate 110 has less support, and the first fixing seat 113 and the second fixing seat 211 are connected to make the connection between the air duct plate 110 and the heat exchanger 200 more stable, further improving the sealing performance between the air duct frame 100 and the heat exchanger 200.

[0073] In some embodiments of the present invention, there are multiple first fixing seats 113 , and the multiple first fixing seats 113 are evenly spaced apart along the vertical direction.

[0074] In some embodiments of the present invention, Figure 1 or Figure 2 As shown, the air duct plate 110 and the raised ribs 300 are an integrally formed structure.

[0075] In this embodiment, the air duct plate 110 and the raised rib 300 are integrally formed, which prevents the raised rib 300 from falling off the air duct plate 110, improves the connection strength between the air duct plate 110 and the raised rib 300, and helps to extend the service life of the air conditioner indoor unit.

[0076] Moreover, the integrally formed structure of the air duct plate 110 and the raised rib 300 does not require separate assembly, making the manufacture and installation of the air duct plate 110 and the raised rib 300 simpler, saving the manufacturing time and cost of the air duct plate 110 and the raised rib 300.

[0077] In some embodiments of the present invention, the heat exchanger 200 is an evaporator.

[0078] In some embodiments of the present invention, the air-conditioning indoor unit is a vertical air-conditioning indoor unit.

[0079] The present invention also provides an air conditioner, comprising an indoor air conditioner and an outdoor air conditioner according to any one of the above embodiments. The outdoor air conditioner is connected to the indoor air conditioner.

[0080] In this embodiment, the duct frame 100 is directly connected to the heat exchanger 200, and condensation water is easily generated on the duct frame 100. The raised ribs 300 arranged obliquely toward the lower side away from the heat exchanger 200 guide the condensation water to the side away from the heat exchanger 200, thereby avoiding the condensation water formed on the duct frame 100 from accumulating on the heat exchanger 200, thereby avoiding the heat exchanger 200 from malfunctioning due to excessive condensation water on the heat exchanger 200, and improving the service life of the air conditioner indoor unit.

[0081] Over long-term use, the duct support 100 is susceptible to deformation due to factors such as internal and external pressure and temperature changes, which can lead to air leakage between the duct support 100 and the heat exchanger 200. The raised ribs 300, designed on the side of the duct plate 110 near the tube sheet 210, strengthen the structural strength of the duct support 100, preventing the air duct from deforming and improving the sealing effect between the duct support 100 and the heat exchanger 200.

[0082] To ensure the seal between the duct frame 100 and the heat exchanger 200 and ensure the stability of the connection, some existing air conditioner indoor units use a large number of sealing sheet metal parts. The use of sealing sheet metal parts not only increases the manufacturing cost of the air conditioner indoor unit but can also reduce the sealing effect due to improper installation or long-term use. The air duct plate 110 with raised ribs 300 replaces some of the functions of the sealing sheet metal parts to a certain extent, thereby reducing the number of sealing sheet metal parts used, lowering the cost of the air conditioner indoor unit, and simplifying the maintenance and service of the air conditioner indoor unit.
