To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0042] Implementation Method 1:

[0043] Please refer to Figures 1-3. The air conditioner indoor unit 100 of this application embodiment includes a first machine 10 and a second machine 20. The first machine 10 includes a first housing 11, and the second machine 20 includes a second housing 21. The first housing 11 and the second housing 21 are separate structures, and are connected as one unit by a first connector 30.

[0044] Thus, the first housing 11 and the second housing 21 are separate structures, which facilitates the handling of the air conditioner indoor unit 100. The first connector 30 can connect the first housing 11 and the second housing 21 into one unit, which facilitates the installation of the air conditioner indoor unit 100 and improves assembly efficiency.

[0045] Specifically, the first box 11 and the second box 21 can be cubic structures, and the first connecting member 30 can be a fastener such as a screw or bolt, or a wire structure such as steel wire or iron wire.

[0046] Please refer to Figures 1-3. In some embodiments, the first machine 10 includes a first connecting plate 12, and the first housing 11 includes a first top plate 111 and a first side plate 112 connected to the first top plate 111. The first connecting plate 12 extends from the first side plate 112 along a first direction D1 and protrudes from the first side plate 112. The second machine 20 is arranged side by side with the first machine 10 along a second direction D2. The second machine 20 includes a second connecting plate 22, and the second housing 21 includes a second top plate 211 and a second side plate 212 connected to the second top plate 211. The second connecting plate 22 extends from the second side plate 212 along the first direction D1 and protrudes from the second side plate 212. The second connecting plate 22 is stacked and connected to the first connecting plate 12. The second connecting plate 22 is fastened to the first connecting plate 12 by a first connector 30. The first direction D1 intersects with the second direction D2.

[0047] Thus, by fastening the second connecting plate 22 and the first connecting plate 12 with the first connecting plate 30 through the first connecting piece 30, the first machine 10 and the second machine 20 can be spliced ​​together, making it easy to assemble and disassemble the first machine 10 and the second machine 20. Furthermore, the first connecting plate 12 is located outside the first housing 11, and the second connecting plate 22 is located outside the second housing 21. The first connecting plate 12 and the second connecting plate 22 are easy to align, and the positioning difficulty is low, which helps to improve assembly efficiency.

[0048] Specifically, the first top plate 111 refers to the plate-like structure located on the upper side of the first housing 11 under normal use. The first top plate 111 is perpendicular to the first side plate 112, and the first side plate 112 extends downward from the end of the first top plate 111 along the first direction D1. The first connecting plate 12 is perpendicular to the first top plate 111 and the first side plate 112.

[0049] The second top plate 211 refers to the plate-like structure located on the upper side of the second housing 21 under normal use. The second top plate 211 is perpendicular to the second side plate 212, and the second side plate 212 extends downward from the end of the second top plate 211 along the first direction D1. The second connecting plate 22 is perpendicular to the second top plate 211 and the second side plate 212.

[0050] The first direction D1 can be the length direction of the first box 11, and the second direction D2 can be the width direction of the first box 11. The first direction D1 and the second direction D2 are perpendicular.

[0051] Referring to Figures 2 and 3, in some embodiments, the first housing 11 forms a first receiving cavity 113, the second housing 21 forms a second receiving cavity 213, and the second machine 20 includes a partition 23 disposed between the first receiving cavity 113 and the second receiving cavity 213, the partition 23 protruding from the edge portion of the second housing 21 to form a second connecting plate 22.

[0052] In this way, the partition 23 can separate the first receiving cavity 113 and the second receiving cavity 213, reducing interference between the components in the first receiving cavity 113 and the components in the second receiving cavity 213.

[0053] Specifically, the first receiving cavity 113 can be formed by the first top plate 111 and the first side plate 112, and the first receiving cavity 113 can accommodate components such as the heat exchanger assembly 15. The second receiving cavity 213 can be formed by the second top plate 211, the second side plate 212 and the partition 23, and the second receiving cavity 213 can accommodate components such as the fan.

[0054] The partition 23 can be formed with through holes, and the air outlet of the fan can correspond to the through holes to connect the first receiving cavity 113 and the second receiving cavity 213, which is conducive to the airflow in the first receiving cavity 113 and the second receiving cavity 213.

[0055] Please refer to Figures 2 and 3. In some embodiments, the first machine 10 includes a first reinforcing plate 13, which connects the first side plate 112 and the first connecting plate 12. A first connector 30 passes through the first reinforcing plate 13, the first connecting plate 12, and the second connecting plate 22.

[0056] Thus, the first reinforcing plate 13 can increase the connection strength between the first side plate 112 and the first connecting plate 12, which is beneficial to improving the stability of the connection between the first housing 11 and the second housing 21.

[0057] Specifically, the first reinforcing plate 13 can be an L-shaped structure, with one part of the first reinforcing plate 13 connected to the first side plate 112 and the other part connected to the first connecting plate 12. The first reinforcing plate 13, the first connecting plate 12 and the second connecting plate 22 can be formed with through holes, and the first connecting member 30 passes through the through holes to fix the first reinforcing plate 13, the first connecting plate 12 and the second connecting plate 22 together.

[0058] Please refer to Figure 3. In some embodiments, the first connecting plate 12 is connected to the edge of the first side plate 112 and is an integral structure with the first side plate 112.

[0059] Thus, the first connecting plate 12 and the first side plate 112 are integrated into one structure, which can reduce the number of parts of the first machine 10, improve the assembly convenience of the first housing 11, and thus improve the production efficiency of the first machine 10.

[0060] Specifically, the first connecting plate 12 and the first side plate 112 can be integrally formed by stamping or by welding.

[0061] Please refer to Figures 2 and 4. In some embodiments, there are two first side plates 112, which are connected to opposite sides of the first top plate 111. The first connecting plate 12 is arranged in a one-to-one correspondence with the first side plates 112. There are two second side plates 212, which are connected to opposite sides of the second top plate 211. The second connecting plate 22 is arranged in a one-to-one correspondence with the second side plates 212. The first connecting plate 12 and the second connecting plate 22 on the same side are stacked and connected together.

[0062] Thus, the first connecting plate 12 and the second connecting plate 22 on the same side are stacked and connected, which makes the thickness of the connection between the first housing 11 and the second housing 21 larger, thereby improving the connection strength between the first housing 11 and the second housing 21 and improving the stability of the air conditioner indoor unit 100.

[0063] Specifically, two first side plates 112 are connected to opposite sides of the first top plate 111 along the first direction D1, and there are two first connecting plates 12, which are respectively connected to one side of the first side plate 112 away from the other side plate 112.

[0064] Two second side plates 212 are connected to the two opposite sides of the second top plate 211 along the first direction D1. There are two second connecting plates 22, and the two second connecting plates 22 are respectively connected to one side of the second side plate 212 away from the other side plate 212.

[0065] Please refer to Figure 3. In some embodiments, a first seal 40 is provided between the first connecting plate 12 and the second connecting plate 22.

[0066] Thus, the first sealing element 40 enables a sealed connection between the first connecting plate 12 and the second connecting plate 22, which is beneficial for a stable connection between the first connecting plate 12 and the second connecting plate 22. At the same time, it avoids direct contact between the first connecting plate 12 and the second connecting plate 22, reduces friction, and thus extends the service life of the first connecting plate 12 and the second connecting plate 22.

[0067] Specifically, the first sealing element 40 can be a foam or sponge, and its shape and size can be the same as those of the first connecting plate 12 and the second connecting plate 22. The first sealing element 40 can be fixed to the first connecting plate 12 or the second connecting plate 22 by adhesive bonding.

[0068] Please refer to Figures 5 and 6. In some embodiments, the second top plate 211 includes a body 214 and a protrusion 215. The protrusion 215 protrudes from the body 214 along the second direction D2 beyond the edge of the second side plate 212. The protrusion 215 is stacked and abuts against the first top plate 111. The protrusion 215 and the first top plate 111 are fastened by a second connector 50 passing through the protrusion 215 and the first top plate 111.

[0069] Thus, by fixing the protrusion 215 to the first top plate 111, the positioning difficulty of the first top plate 111 and the second top plate 211 can be reduced. In addition, the second connector 50 can achieve a stable connection between the first top plate 111 and the second top plate 211.

[0070] Specifically, the body 214 and the protrusion 215 can be integrally formed or fixed by welding or other means. The protrusion 215 can extend along the second direction D2 toward the direction close to the first machine 10, and the protrusion 215 can be located on the side of the first top plate 111 away from the first side plate 112.

[0071] The protrusion 215 and the first top plate 111 may have through holes, and the second connector 50 passes through the through holes to fix the protrusion 215 and the first top plate 111 together. The second connector 50 may be a fastener such as a screw or bolt, or it may be a wire structure such as steel wire or iron wire.

[0072] Referring to Figure 6, in some embodiments, the first top plate 111 includes a flat plate portion 114 and a bent portion 115, the bent portion 115 bends downward from the flat plate portion 114, the protrusion 215 abuts against the flat plate portion 114, and the second connector 50 passes through the protrusion 215 and the flat plate portion 114.

[0073] Thus, the bending portion 115 can increase the structural strength of the first top plate 111, and the downward bending of the bending portion 115 can reduce the height space occupied by the first housing 11, making the overall height of the air conditioner indoor unit 100 lower, which is conducive to the miniaturization of the air conditioner indoor unit 100.

[0074] Specifically, the flat plate portion 114 and the bent portion 115 can be integrally formed or fixed by welding or other methods. The flat plate portion 114 and the bent portion 115 can be set at a 90° angle, and the connection between the flat plate portion 114 and the bent portion 115 can be a rounded chamfer. The downward extension length of the bent portion 115 can be designed according to actual needs.

[0075] Referring to Figure 6, in some embodiments, the first machine 10 includes a second reinforcing plate 116 connecting the flat plate portion 114 and the bent portion 115, and a second connector 50 passes through the protrusion 215, the flat plate portion 114 and the second reinforcing plate 116.

[0076] Thus, the second reinforcing plate 116 can increase the connection strength between the flat plate portion 114 and the bent portion 115, thereby increasing the structural strength of the first housing 11 and extending the service life of the first machine 10.

[0077] Specifically, the second reinforcing plate 116 can be located on the side of the first top plate 111 away from the protrusion 215. The second reinforcing plate 116 can be a U-shaped structure. The bottom wall of the second reinforcing plate 116 abuts against the flat plate portion 114. One side wall of the second reinforcing plate 116 abuts against the bent portion 115. The second connecting member 50 passes through the bottom wall of the second reinforcing plate 116.

[0078] Referring to Figure 6, in some embodiments, the partition 23 includes a mounting portion 231 and an isolation portion 232. The isolation portion 232 is bent downward from the mounting portion 231, and the body 214 abuts against the mounting portion 231. The second machine includes a third reinforcing plate 233 connecting the mounting portion 231 and the isolation portion 232. The body 214, the mounting portion 231, and the third reinforcing plate 233 are fastened by a third connector passing through the body 214, the mounting portion 231, and the third reinforcing plate 233.

[0079] Thus, the third reinforcing plate 233 can increase the connection strength between the mounting part 231 and the isolation part 232, thereby increasing the structural strength of the second housing 21 and extending the service life of the second machine 20.

[0080] Specifically, the third reinforcing plate 233 can be located on the side of the partition 23 away from the first top plate 111 and the second top plate 211. The third reinforcing plate 233 can be an L-shaped structure. The bottom wall of the third reinforcing plate 233 abuts against the mounting part 231, the side wall of the third reinforcing plate 233 abuts against the isolation part 232, and the third connector passes through the bottom wall of the third reinforcing plate 233.

[0081] The third connector can be a fastener such as a screw or bolt, or it can be a wire structure, such as steel wire or iron wire.

[0082] Please refer to Figures 5 and 6. In some embodiments, the first housing 11 forms a first receiving cavity 113, the second housing 21 forms a second receiving cavity 213, and the second machine 20 includes a partition 23 disposed between the first receiving cavity 113 and the second receiving cavity 213, with the bent portion 115 abutting against the partition 23.

[0083] Thus, the abutment between the bent portion 115 and the partition 23 facilitates the installation and alignment between the first housing 11 and the second housing 21, reducing the difficulty of positioning.

[0084] Specifically, the part of the bent portion 115 near the second housing 21 may abut against the partition 23, or the entire surface of the bent portion 115 near the second housing 21 may abut against the partition 23.

[0085] Please refer to Figure 6. In some embodiments, a second seal 60 is provided between the protrusion 215 and the first top plate 111.

[0086] Thus, the second seal 60 can achieve a sealed connection between the protrusion 215 and the first top plate 111, which is beneficial to the stable connection between the protrusion 215 and the first top plate 111. At the same time, it can avoid direct contact between the protrusion 215 and the first top plate 111, reduce friction, and thus extend the service life of the protrusion 215 and the first top plate 111.

[0087] Specifically, the second seal 60 can be located between the protrusion 215 and the flat plate 114. The second seal 60 can be a foam or sponge, and its shape and size can be the same as the shape and size of the overlapping portion of the protrusion 215 and the flat plate 114. The second seal 60 can be fixed to the protrusion 215 or the flat plate 114 by adhesive bonding.

[0088] Please refer to Figures 5 and 7. In some embodiments, the second machine 20 includes a chassis 24, which includes a mounting part 240, and the first machine 10 and the second machine 20 are connected through the mounting part 240.

[0089] Thus, the bottom of the first machine 10 and the second machine 20 can be positioned by the mounting part 240, which facilitates the connection of the bottom of the first machine 10 and the second machine 20.

[0090] Please refer to Figures 5 and 7. In some embodiments, the chassis 24 includes a base plate portion 241, and the mounting portion 240 includes a connecting portion 242 and an abutting portion 243. The connecting portion 242 connects the base plate portion 241 and the abutting portion 243. The connecting portion 242 extends upward from the base plate portion 241, and the abutting portion 243 extends from the connecting portion 242 toward the first machine 10. The first machine 10 includes a water receiving tray 14, which includes a surrounding plate 141. The abutting portion 243 abuts against the top surface of the surrounding plate 141, and the connecting portion 242 abuts against the side surface of the surrounding plate 141.

[0091] Thus, the abutment portion 243 facilitates the limiting of the first housing 11 and the second housing 21, thereby restricting the relative movement of the first machine 10 and the second machine 20 in the height direction, which helps to improve the installation stability of the first machine 10 and the second machine 20.

[0092] Specifically, the base plate 241, the connecting part 242, and the abutting part 243 can be integrally formed or fixed by welding or other methods. The abutting part 243 can partially abut against the top surface of the enclosure 141, and the connecting part 242 can partially abut against the side of the enclosure 141.

[0093] Please refer to Figures 5 and 7. In some embodiments, the hook-on portion 240 further includes a limiting portion 244 that connects to the abutment portion 243. The limiting portion 244 extends downward from the abutment portion 243 into the water receiving tray 14. The connecting portion 242 and the limiting portion 244 are located on opposite sides of the enclosure 141.

[0094] Thus, the limiting part 244 and the connecting part 242 facilitate the limiting of the first housing 11 and the second housing 21, and the relative movement of the first machine 10 and the second machine 20 in the second direction D2 can be restricted without the need for connecting parts, thereby improving the installation stability of the first machine 10 and the second machine 20.

[0095] Specifically, the limiting part 244 can be integrally formed with the abutting part 243, or it can be fixed by welding or other means. The length of the abutting part 243 along the second direction D2 can be greater than the length of the surrounding plate 141 along the second direction D2, so that the distance between the connecting part 242 and the limiting part 244 is greater than the length of the surrounding plate 141 along the second direction D2, thereby allowing the surrounding plate 141 to be located between the connecting part 242 and the limiting part 244.

[0096] Please refer to Figures 5 and 7. In some embodiments, the hook portion 240 further includes a guide portion 245 that connects to the limiting portion 244. The guide portion 245 extends obliquely from the limiting portion 244 in a direction away from the connecting portion 242.

[0097] In this way, the guide part 245 can play a guiding role when the chassis 24 is against the water receiving tray 14, reducing the difficulty of installation.

[0098] Specifically, the guide portion 245 is integrally formed with the limiting portion 244, or it can be fixed by welding or other methods. The included angle formed between the guide portion 245 and the connecting portion 242 can be an obtuse angle. In one embodiment, the included angle formed between the guide portion 245 and the connecting portion 242 is 135°.

[0099] Please refer to Figure 7. In some embodiments, a third seal 70 is provided between the abutment portion 243 and the top surface of the enclosure 141.

[0100] Thus, the third seal 70 can achieve a sealed connection between the abutment portion 243 and the surrounding plate 141, which is beneficial to the stable connection between the abutment portion 243 and the surrounding plate 141. At the same time, it can avoid direct contact between the abutment portion 243 and the surrounding plate 141, reduce friction, and thus extend the service life of the abutment portion 243 and the surrounding plate 141.

[0101] Specifically, the third seal 70 can be a foam or sponge, and its shape and size can be the same as the shape and size of the overlapping portion of the abutment 243 and the surrounding plate 141. The third seal 70 can be fixed to the abutment 243 or the surrounding plate 141 by adhesive bonding.

[0102] In one embodiment, the hook part 240 is first hung on the enclosure 141 to limit the first housing 11 and the second housing 21 in the second direction D2, preventing the first housing 11 and the second housing 21 from detaching in the second direction D2 without the need for connectors, thus facilitating the bottom connection of the first machine 10 and the second machine 20; then, the protrusion 215 abuts against the flat plate 114 to further position the first housing 11 and the second housing 21 in the second direction D2, reducing the difficulty of positioning the first housing 11 and the second housing 21 in the second direction D2; then, the second connecting plate 22 is stacked and mated with the first connecting plate 12 to... The first housing 11 and the second housing 21 are positioned in the first direction D1, reducing the difficulty of positioning them in this direction. Finally, the protrusion 215 and the flat plate 114 are fastened together by the second connector 50 to achieve a fixed connection at the top of the first housing 11 and the second housing 21, restricting their relative movement in the height direction. The first connecting plate 12 and the second connecting plate 22 are fastened together by the first connector 30 to achieve a fixed connection on the sides of the first housing 11 and the second housing 21, restricting their relative movement in the first direction D1. Through the above embodiments, the first housing 11 and the second housing 21 are easy to assemble and disassemble, facilitating the disassembly, transportation, and installation of the air conditioner indoor unit 100, and improving assembly and disassembly efficiency.

[0103] Referring to Figures 8 and 9, in some embodiments, the first machine 10 includes a heat exchanger assembly 15 disposed within a first housing 11, the heat exchanger assembly 15 including a heat exchanger 151 and a heat exchanger side plate 152.

[0104] Thus, the heat exchanger 151 can be connected to other components through the heat exchanger side plate 152.

[0105] Specifically, the heat exchanger 151 can be installed on the water receiving pan 14. The heat exchanger 151 can condense water vapor in the air to form condensate. The condensate drips down under the action of gravity. Therefore, the water receiving pan 14 is used to collect the condensate formed by the heat exchanger 151, reducing the risk of condensate flowing to other places and causing adverse effects.

[0106] The heat exchanger 151 can be arranged at an angle. The angled placement of the heat exchanger 151 can reduce the height space occupied by the heat exchanger 151 after installation, so that the overall height of the air conditioner indoor unit 100 is lower, which is conducive to the miniaturization of the air conditioner indoor unit 100, thereby reducing the weight of the air conditioner indoor unit 100 and facilitating the installation, handling and installation of the air conditioner indoor unit.

[0107] Please refer to Figures 8 and 9. In some embodiments, the heat exchanger 151 includes a refrigerant pipe 153, and the first machine 10 includes a distributor inlet pipe 17, an electronic expansion valve assembly 18, and a support plate 19. The distributor inlet pipe 17 and the electronic expansion valve assembly 18 are fixed to the support plate 19, and both the distributor inlet pipe 17 and the electronic expansion valve assembly 18 are in communication with the refrigerant pipe 153. The support plate 19 is fixed to the heat exchanger side plate 152.

[0108] Thus, the distributor inlet pipe 17 and the electronic expansion valve assembly 18 are fixed on the support plate 19, and the support plate 19 is fixed on the heat exchanger side plate 152, which can achieve effective fixing of the distributor inlet pipe 17 and the electronic expansion valve assembly 18 with the refrigerant pipe 153 and ensure consistency in production.

[0109] Specifically, refrigerant pipe 153 can pass through heat exchanger 151 along its length and is used to transport refrigerant. Distributor inlet pipe 17 includes a main pipe 171 and multiple branch pipes 172. One end of the main pipe 171 is connected to the electronic expansion valve assembly 18, and the other end is connected to the multiple branch pipes 172. The end of each branch pipe 172 away from the main pipe 171 passes through the heat exchanger side plate 152 and connects to the refrigerant pipe 153. Heat exchanger 151 can include multiple refrigerant pipes 153, each corresponding to one of the multiple branch pipes 172. Refrigerant flows into distributor inlet pipe 17 after being throttled by electronic expansion valve assembly 18, and then flows through distributor inlet pipe 17 to each refrigerant pipe 153.

[0110] The distributor inlet pipe 17, the electronic expansion valve assembly 18, and the support plate 19 can be located on the side of the heat exchanger assembly 15 closer to the second machine 20.

[0111] The support plate 19 can be a bent structure. The support plate 19 includes a first bent portion 191, a second bent portion 192 and a third bent portion 193. The first bent portion 191 and the third bent portion 193 are perpendicular to the second bent portion 192 and are located on opposite sides of the second bent portion 192.

[0112] A through hole may be formed at the end of the first bend 191 near the distributor input pipe 17, through which a metal wire or cable tie can be used to fix the first bend 191 and the distributor input pipe 17. A through hole may also be formed at the end of the first bend 191 near the electronic expansion valve assembly 18, through which a metal wire or cable tie can be used to fix the first bend 191 and the electronic expansion valve assembly 18.

[0113] The third bend 193 can be fixed to the side of the heat exchanger side plate 152 near the second machine 20 by bolts or other fasteners.

[0114] Please refer to Figure 10. The air conditioning system 1000 of this application includes an indoor unit 100 and an outdoor unit 200 as described in any of the above embodiments. The outdoor unit 200 and the indoor unit 100 are connected by pipes. Specifically, the outdoor unit 200 may include components such as a compressor. During operation, the compressor can perform work on the refrigerant, allowing the refrigerant to exchange heat with the heat exchanger 151, thereby regulating the indoor temperature.

[0115] Implementation Method Two:

[0116] Please refer to Figures 11-14. An embodiment of this application provides an air conditioner indoor unit 100 including a heat exchanger 151 and a first sealing component 2030. The heat exchanger 151 is inclinedly disposed in a first housing 11 and includes an upper end face 2021. The first sealing component 2030 is disposed in the first housing 11 and includes a first inclined surface 2031 that cooperates with the upper end face 2021.

[0117] Thus, the first sealing component 2030 can seal the gap between the upper end face 2021 of the heat exchanger 151 and the first housing 11, preventing air passing through the heat exchanger 151 from leaking out through the gap and affecting the heat exchange effect of the heat exchanger 151. At the same time, the first sealing component 2030 can also achieve a heat insulation function. By having the first inclined surface 2031 of the first sealing component 2030 cooperate with the upper end face 2021 of the heat exchanger 151, the installation of the first sealing component 2030 is facilitated, thereby improving the overall production efficiency of the air conditioning indoor unit 100.

[0118] The first housing 11 can be a cuboid structure, and the first sealing component 2030 can be located within the angled area formed by the first top plate 111 and the back plate of the first housing 11. The heat exchanger 151 can be a flat plate heat exchanger 151, and the tilt angle of the heat exchanger 151 can be 30°, 45°, 60°, etc. The tilt degree of the first tilted surface 2031 can be the same as the tilt degree of the upper end surface 2021.

[0119] Placing the heat exchanger 151 at an angle can reduce the height space occupied by the heat exchanger 151 after installation, making the overall height of the air conditioner indoor unit 100 lower. This is conducive to the miniaturization of the air conditioner indoor unit 100, thereby reducing the weight of the first casing 11 of the air conditioner indoor unit 100, which is beneficial to the handling and installation of the air conditioner indoor unit 100.

[0120] Please refer to Figures 11 and 12. In some embodiments, the first housing 11 includes a first top plate 111, and the first sealing member 2030 includes a top surface 2032, which abuts against the first top plate 111.

[0121] Thus, the top surface 2032 of the first sealing component 2030 abuts against the first top plate 111 of the first housing 11, which can seal the gap between the first housing 11 and the first sealing component 2030, preventing the air passing through the heat exchanger 151 from leaking out from the gap between the first top plate 111 and the first sealing component 2030, thus affecting the heat exchange effect of the heat exchanger 151.

[0122] Specifically, the first top plate 111 refers to the plate-like structure located on the upper side of the first housing 11 under normal use. The top surface 2032 refers to the surface of the first housing 11 facing the first top plate 111 under normal use. The first top plate 111 of the first housing 11 can cover the top surface 2032 of the first sealing member 2030.

[0123] Referring to Figure 12, in some embodiments, the first sealing member 2030 is provided with a groove 2033 recessed downward from the top surface 2032, and the groove 2033 extends along the length direction of the first sealing member 2030.

[0124] Thus, the groove 2033 can reduce the weight of the first sealing component 2030 and also reduce the amount of material used in the first sealing component 2030, thereby reducing the production cost of the first sealing component 2030.

[0125] Specifically, the groove 2033 can be formed during the molding of the first sealing component 2030, or it can be formed after the first sealing component 2030 has been molded by removing part of the material. The cross-sectional shape of the groove 2033 can be a regular shape such as square, trapezoid, triangle, or circle, or it can be an irregular shape. The length direction of the first sealing component 2030 can be the same as the length direction of the heat exchanger 151.

[0126] In one embodiment, the cross-section of the groove 2033 is a right trapezoid, the inclination of the trapezoidal slope in the groove 2033 is the same as the inclination of the first inclined surface 2031, and the width from the outer surface of the first sealing member 2030 to the groove wall surface corresponding to the groove 2033 is equal, so as to reduce the amount of material used in the first sealing member 2030 as much as possible while ensuring the structural strength of the first sealing member 2030.

[0127] Please refer to Figure 12. In some embodiments, the groove 2033 is provided with a reinforcing rib 2034, which is connected to the groove wall surface of the groove 2033.

[0128] Thus, the reinforcing rib 2034 can improve the structural strength of the first sealing component 2030, thereby extending the service life of the first sealing component 2030.

[0129] Specifically, the reinforcing rib 2034 can be made of foam material. Furthermore, the material of the reinforcing rib 2034 can be the same as that of the first sealing component 2030, and the reinforcing rib 2034 and the first sealing component 2030 can be integrally molded. The reinforcing rib 2034 can be connected to the top surface 2032 of the first sealing component 2030.

[0130] Please refer to Figure 12. In some embodiments, the reinforcing rib 2034 connects the two groove walls in the width direction of the groove 2033. There are multiple reinforcing ribs 2034, which are arranged at intervals along the length direction of the first sealing member 2030.

[0131] Thus, multiple reinforcing ribs 2034 can significantly improve the structural strength of the first sealing component 2030, thereby effectively extending the service life of the first sealing component 2030.

[0132] Specifically, the shape of the reinforcing rib 2034 can be the same as the cross-sectional shape of the groove 2033. For example, when the cross-sectional shape of the groove 2033 is a right trapezoid, the reinforcing rib 2034 is a right trapezoid; when the cross-sectional shape of the groove 2033 is a triangle, the reinforcing rib 2034 is a triangle.

[0133] The number of reinforcing ribs 2034 can be 2, 3, 4, 5, 6 or more. Multiple reinforcing ribs 2034 cause the first sealing member 2030 to form multiple grooves 2033. The length of each groove 2033 along the length direction of the first sealing member 2030 can be the same or different. The number, position, and spacing of the reinforcing ribs 2034 can be designed according to actual needs. In this embodiment, the number of reinforcing ribs 2034 is 3, and the first sealing member 2030 forms 4 grooves 2033 of equal length.

[0134] Please refer to Figures 11 and 12. In some embodiments, the top surface 2032 is provided with a sealing rib 2035, which surrounds the periphery of the top surface 2032 and abuts against the first top plate 111.

[0135] Thus, the sealing rib 2035 can seal the gap between the first sealing component 2030 and the first top plate 111, thereby enhancing the sealing effect between the heat exchanger 151 and the first housing 11.

[0136] Specifically, the material of the sealing rib 2035 can be the same as that of the first sealing component 2030, the sealing rib 2035 can be integrally formed with the first sealing component 2030, and the sealing rib 2035 can protrude from the top surface 2032.

[0137] The sealing rib 2035 is arranged around the periphery of the top surface 2032, which means that the sealing rib 2035 can surround the periphery of the whole formed by multiple grooves 2033, that is, the multiple grooves 2033 are located in the space enclosed by the sealing rib 2035.

[0138] The sealing rib 2035 and the first top plate 111 can be interference-fitted to improve the sealing performance of the first sealing component 2030 and the first top plate 111.

[0139] In some embodiments, the height of the sealing rib 2035 ranges from 1 mm to 4 mm; and / or, the width of the sealing rib 2035 ranges from 3 mm to 7 mm.

[0140] Thus, when the size of the sealing rib 2035 is within the above range, the sealing effect between the first sealing component 2030 and the first top plate 111 can be improved.

[0141] Specifically, the height of the sealing rib 2035 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. The width of the sealing rib 2035 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, etc.

[0142] In one embodiment, the cross-sectional width of the sealing rib 2035 decreases from the top surface 2032 toward the direction away from the groove 2033, the height of the sealing rib 2035 can be the distance from the apex of the sealing rib 2035 to the top surface 2032, and the width of the sealing rib 2035 can be the distance between the cross-section of the sealing rib 2035 and the two connection points of the top surface 2032.

[0143] Please refer to Figures 11 and 12. In some embodiments, the first housing 11 includes two opposing first side plates 112, and the first sealing member 2030 is sandwiched in the enclosed space formed by the two first side plates 112 and the first top plate 111.

[0144] Specifically, the first side plate 112 can be spaced at both ends of the first top plate 111 along the length of the heat exchanger 151.

[0145] Thus, by clamping the first sealing component 2030 between the two first side plates 112, the first sealing component 2030 can be limited in the length direction of the heat exchanger 151, reducing the shaking of the first sealing component 2030 in the length direction, thereby improving the installation stability of the first sealing component 2030.

[0146] Please refer to Figures 13-15. In some embodiments, the first sealing member 2030 includes a body 2036 and a first protrusion 2037 protruding downward from a first end of the body 2036. The air conditioner indoor unit 100 includes a support member 2050 disposed on one side of the heat exchanger 151 in the length direction, and the first protrusion 2037 abuts against the support member 2050.

[0147] Thus, the support member 2050 can provide support for the first protrusion 2037, thereby providing support for the first end of the first sealing member 2030.

[0148] Specifically, the first protrusion 2037 can be integrally formed with the body 2036, and the first protrusion 2037 can abut against the support member 2050 through its bottom surface. The bottom surface of the first protrusion 2037 can be a flat surface, or it can be an arc-shaped surface, a wavy surface, a sawtooth surface, etc. The first protrusion 2037 can be interference-fitted with the support member 2050 to achieve stable support of the first end of the first sealing member 2030 by the support member 2050.

[0149] Please refer to Figures 12, 14, 16 and 17. In some embodiments, the indoor unit 100 of the air conditioner includes a mounting plate 2060 and a baffle 2013. The mounting plate 2060 is disposed on one side of the heat exchanger 151 along its length. The heat exchanger 151 is mounted on the mounting plate 2060. A support member 2050 is disposed between the mounting plate 2060 and the baffle 2013. The ends of the mounting plate 2060, the baffle 2013 and the support member 2050 surround to form a slot 2061. A first protrusion 2037 is engaged in the slot 2061.

[0150] Thus, by engaging the first protrusion 2037 in the slot 2061, the first protrusion 2037 can be fixed in a limited position. The first sealing component 2030 can be fixed without screws or other mounting parts, making the installation simple.

[0151] Specifically, the mounting plate 2060 can be formed from metal material by stamping. Referring to Figures 18 and 19, the mounting plate 2060 can be a bent structure, including a first bent portion 2062, a second bent portion 2063, and a third bent portion 2064. The second bent portion 2063 is a right-angled trapezoidal plate structure. The first bent portion 2062 and the third bent portion 2064 are both elongated structures. The first bent portion 2062 and the third bent portion 2064 are perpendicular to the second bent portion 2063 and are located on opposite sides of the second bent portion 2063.

[0152] The hypotenuse of the second bend 2063 is connected to the first bend 2062. The right-angled side of the second bend 2063 opposite to the hypotenuse is connected to the third bend 2064. The first bend 2062 is fixedly connected to the heat exchanger 151 by screws or other fasteners. The support member 2050 is in contact with the second bend 2063 and the third bend 2064. The third bend 2064 is fixedly connected to the support member 2050 by screws or other fasteners. The baffle 2013 is located on the side of the support member 2050 opposite to the second bend 2063.

[0153] The upper surface of the support member 2050 can be lower than the upper surfaces of the mounting plate 2060 and the baffle 2013. Therefore, the slot 2061 can be formed by the side of the second bend 2063, the side of the third bend 2064, the side of the baffle 2013 and the upper surface of the support member 2050. The first protrusion 2037 is engaged in the slot 2061, that is, the bottom surface of the first protrusion 2037 abuts against the upper surface of the support member 2050.

[0154] Please refer to Figures 15 and 20. In some embodiments, the first sealing member 2030 includes a body 2036 and a second protrusion 2038 protruding downward from the second end of the body 2036. The air conditioner indoor unit 100 includes a heat exchanger side plate 2022 disposed on one side of the heat exchanger 151 in the length direction, and the second protrusion 2038 abuts against the heat exchanger side plate 2022.

[0155] Thus, the heat exchanger side plate 2022 can provide support for the second protrusion 2038, thereby providing support for the second end of the first sealing member 2030. The first protrusion 2037 and the second protrusion 2038 can effectively prevent the movement of the first sealing member 2030, which is beneficial to enhancing the sealing effect between the heat exchanger 151 and the first housing 11.

[0156] Specifically, the second protrusion 2038 can be integrally formed with the body 2036, and the second protrusion 2038 can abut against the heat exchanger side plate 2022 through its side near the first protrusion 2037. The second protrusion 2038 can be interference-fitted with the heat exchanger side plate 2022 to achieve stable support of the second end of the first sealing component 2030 by the heat exchanger side plate 2022.

[0157] Referring to Figure 14, in some embodiments, the indoor unit 100 of the air conditioner includes a first sealing sheet 2070 disposed between the upper end face 2021 and the first inclined face 2031, the first sealing sheet 2070 sealing the gap between the first inclined face 2031 and the upper end face 2021.

[0158] Thus, by sealing the gap between the first sealing component 2030 and the upper end face 2021 of the heat exchanger 151 with the first sealing plate 2070, the sealing performance between the first sealing component 2030 and the heat exchanger 151 can be improved, thereby improving the heat exchange effect of the heat exchanger 151.

[0159] Specifically, the material of the first sealing sheet 2070 and the first sealing component 2030 can be the same or different. For example, both the first sealing sheet 2070 and the first sealing component 2030 can be made of foam; or, for example, the first sealing component 2030 can be made of plastic and the first sealing sheet 2070 can be made of sponge. The first sealing sheet 2070 can be integrally molded with the first sealing component 2030.

[0160] The heat exchanger 151 and the first sealing plate 2070 can be interference-fitted to improve the sealing performance of the heat exchanger 151 and the first sealing plate 2070.

[0161] In some embodiments, the first sealing component 2030 is a foam component. Because foam has thermal insulation properties, the first sealing component 2030 can achieve a thermal insulation effect. Specifically, the first sealing component 2030 can be made of materials such as polyurethane, polystyrene, polyvinyl chloride, polyethylene, and polypropylene.

[0162] In some embodiments, the first sealing component 2030 is a one-piece molded structure. This reduces the number of parts in the first sealing component 2030, thus improving its manufacturing efficiency. Specifically, the first sealing component 2030 can be formed by molding methods such as calendering or molding.

[0163] Please refer to Figure 14. In some embodiments, the indoor unit 100 of the air conditioner includes a second sealing component 2080 and a water receiving tray 2040 disposed below the heat exchanger 151. The second sealing component 2080 is disposed on the water receiving tray 2040. The heat exchanger 151 includes an inclined lower end face 2023. The second sealing component 2080 includes a second inclined surface 2081 that cooperates with the lower end face 2023.

[0164] Heat exchanger 151 can condense water vapor in the air to form condensate. The condensate drips down under the action of gravity. Therefore, the drip tray 2040 is used to collect the condensate formed by heat exchanger 151, reducing the risk of condensate flowing to other places and causing adverse effects.

[0165] In some embodiments, the second sealing member 2080 is a foam component. The first sealing member 2030 and the second sealing member 2080 may be made of the same material or different materials.

[0166] Referring to Figure 14, in some embodiments, the indoor unit 100 of the air conditioner includes a second sealing plate 2090 disposed between the lower end face 2023 and the second inclined face 2081, the second sealing plate 2090 sealing the gap between the second inclined face 2081 and the lower end face 2023.

[0167] Thus, the second sealing component 2080 can provide support for the heat exchanger 151. At the same time, by sealing the gap between the second sealing component 2080 and the lower end face 2023 of the heat exchanger 151 by the second sealing plate 2090, the sealing performance between the second sealing component 2080 and the heat exchanger 151 can be improved, thereby improving the heat exchange effect of the heat exchanger 151.

[0168] Specifically, the material of the second sealing sheet 2090 can be the same as or different from that of the second sealing component 2080. For example, both the second sealing sheet 2090 and the second sealing component 2080 can be made of foam; or, for example, the second sealing component 2080 can be made of plastic and the second sealing sheet 2090 can be made of sponge. The second sealing sheet 2090 can be integrally molded with the second sealing component 2080.

[0169] The heat exchanger 151 and the second sealing plate 2090 can be interference-fitted to improve the sealing performance of the heat exchanger 151 and the second sealing plate 2090.

[0170] Please refer to Figures 12 and 14. In some embodiments, the lower end face 2023 is higher than the bottom face of the water receiving tray 2040.

[0171] This reduces the risk of condensate in the drip tray 2040 coming into contact with the lower end face 2023 of the heat exchanger 151 and affecting the performance of the heat exchanger 151.

[0172] Specifically, the water receiving tray 2040 can be formed by the bottom plate 2014 of the first housing 11 and the surrounding members 2015 disposed around the bottom plate 2014, and the bottom surface of the water receiving tray 2040 can be the surface of the bottom plate 2014. The second sealing member 2080 can be disposed on the bottom plate 2014, and the heat exchanger 151 can be disposed on the second sealing member 2080, so that the heat exchanger 151 as a whole can be located above the bottom plate 2014, thereby making the lower end face 2023 of the heat exchanger 151 higher than the bottom surface of the water receiving tray 2040.

[0173] Implementation Method 3:

[0174] Please refer to Figures 21-23. The air conditioner indoor unit 100 of this application embodiment includes a handle 3020. At least one of the first housing 11 and the second housing 21 includes an upper end 3011, a lower end 3012 and a middle part 3013. The middle part 3013 is located between the upper end 3011 and the lower end 3012. The thickness of the upper end 3011 is greater than the thickness of the middle part 3013. The handle 3020 is installed on the upper end 3011.

[0175] In the aforementioned air conditioner indoor unit 100, a handle 3020 is provided at the upper end 3011 of the air conditioner indoor unit 100, so that the center of gravity of the air conditioner indoor unit 100 is below the handle 3020. The handle 3020 makes the air conditioner indoor unit 100 easier to move and prevents it from shaking during movement, thus improving the moving efficiency of the air conditioner indoor unit 100. In addition, the thickness of the upper end 3011 is greater than the thickness of the middle part 3013, making the upper end 3011 of at least one of the first housing 11 and the second housing 21 stronger, and the handle 3020 more stable during use.

[0176] Specifically, taking the first housing 11 as an example, the upper end 3011 refers to the end of the first housing 11 located on the upper side under normal use, and the upper end 3011 is located at the upper edge of the first housing 11. Similarly, the lower end 3012 of the first housing 11 is located at the lower edge of the first housing 11.

[0177] The upper part 3011 can be a single-layer board structure or a multi-layer board structure. When the upper part 3011 is a single-layer board structure, the upper part 3011 can be made thicker by locally thickening the single-layer board.

[0178] The handle 3020 can be detachably mounted on the upper end 3011 of the first housing 11, or it can be non-detachably connected to the upper end 3011 of the first housing 11. Understandably, the handle 3020 is a component for gripping. During the handling of the indoor air conditioner unit 100, the operator can grip the handle 3020 to move the indoor air conditioner unit 100 to its destination. The handle 3020 can have a semi-circular structure, a T-shaped structure, a long strip structure, etc.

[0179] Referring to Figures 24-25, in some embodiments, at least one of the first housing 11 and the second housing 21 includes a top plate 3014 and a side plate 3015 connected to the top plate 3014, with a handle 3020 mounted on the side plate 3015 near the edge of the top plate 3014. Thus, the position of the handle 3020 on the side plate 3015 ensures that, after installation, the handle 3020 will not interfere with other components of the indoor unit 100, thereby hindering the handling and installation of the indoor unit 100.

[0180] Specifically, the top panel 3014 is the panel facing upwards when the indoor unit 100 of the air conditioner is in normal use. Taking the first housing 11 as an example, the side panel 3015 is located on one side of the first housing 11. The first housing 11 may also have front and rear panels, which are panels arranged along the airflow direction of the first housing 11. Generally, the panel downstream of the airflow direction is the front panel, and the panel upstream of the airflow direction is the rear panel.

[0181] The top plate 3014 is at least one of the first top plate 111 and the second top plate 211 mentioned above, and the side plate 3015 is at least one of the first side plate 112 and the second side plate 212 mentioned above.

[0182] It should be noted that the handle 3020 is mounted on the edge of the side panel 3015, meaning that the side panel 3015 can provide a mounting base structure for the handle 3020. For example, the handle 3020 can contact the side panel 3015, or it can be mounted on the side panel 3015 through an intermediate medium.

[0183] As shown in Figure 24, in some embodiments, there is at least one side panel 3015, and each side panel 3015 is equipped with a handle 3020. Since the indoor unit 100 of the air conditioner is relatively heavy, at least one side panel 3015 is equipped with a handle 3020, which makes it convenient for multiple operators to move the indoor unit 100 of the air conditioner.

[0184] Specifically, each side panel 3015 may be equipped with one handle 3020 or multiple handles 3020. The number of handles 3020 on each side panel 3015 may be equal or unequal. When the total number of handles 3020 on at least one side panel 3015 is greater than two, the multiple handles 3020 can be arranged around the center of gravity of the air conditioner indoor unit 100, making the air conditioner indoor unit 100 more stable during transportation.

[0185] Please refer to Figures 25 and 26. In some embodiments, the top plate 3014 includes a flat plate portion 30141 and a bent portion 30142 connected to the flat plate portion 30141. The bent portion 30142 is stacked with the side plate 3015. The handle 3020 is installed at the position corresponding to the side plate 3015 and the bent portion 30142. The upper end portion 3011 includes the bent portion 30142.

[0186] Thus, the bent portion 30142 and the side plate 3015 are stacked, which makes the upper end 3011 thicker, thereby increasing the strength of the upper end 3011 and improving the stability of the handle 3020 during use.

[0187] Specifically, the flat plate portion 30141 is located on the top side of the first housing 11 or the second housing 21, and the bent portion 30142 is bent relative to the flat plate portion 30141. The bent portion 30142 and the flat plate portion 30141 can be arranged perpendicularly. The overall area of ​​the bent portion 30142 is smaller than the overall area of ​​the flat plate portion 30141. The flat plate portion 30141 and the bent portion 30142 can be made of the same sheet material and formed by a bending process.

[0188] Referring to Figures 25 and 26, in some embodiments, the bent portion 30142 is located on the outer side of the side plate 3015, and the end of the side plate 3015 abuts against the flat plate portion 30141. Thus, the side plate 3015 can restrict the position of the top plate 3014 and provide support for the top plate 3014, making the connection between the top plate 3014 and the side plate 3015 more stable and improving the structural strength of the first housing 11 or the second housing 21. In the above embodiments, the outer side of the side plate 3015 refers to the side of the side plate 3015 that is away from the internal center of the housing.

[0189] Referring to Figure 26, in some embodiments, the handle 3020 includes a grip portion 3021, a connecting portion 3022, and a mounting portion 3023. The connecting portion 3022 connects the grip portion 3021 and the mounting portion 3023. The mounting portion 3023 fits against the bending portion 30142. The handle 3020 is disposed at the upper end 3011 by a first fastener 3030 passing through the mounting portion 3023, the bending portion 30142, and the side plate 3015 in sequence.

[0190] Thus, the mounting part 3023, the bending part 30142 and the side plate 3015 can overlap, and the position where the handle 3020 is installed has at least two layers of plates, which increases the strength and improves the stability of the handle 3020 installation.

[0191] Specifically, the gripping part 3021, the connecting part 3022, and the mounting part 3023 can all be sheet-like structures, and the gripping part 3021 and the mounting part 3023 can be arranged in parallel. The gripping part 3021, the connecting part 3022, and the mounting part 3023 can be formed by stamping from the same sheet metal, or in other words, the gripping part 3021, the connecting part 3022, and the mounting part 3023 can be an integrally formed structure. Since the bent part 30142 is located on the outside of the side plate 3015, after the mounting part 3023 is attached to the bent part 30142, the contact area between the handle 3020 and the first housing 11 or the second housing 21 is increased, which can further improve the stability of the handle 3020.

[0192] The first fastener 3030 can be a screw, rivet, etc. Understandably, when the first fastener 3030 is a screw, the handle 3020 can be detachably connected to the first housing 11 or the second housing 21.

[0193] Please refer again to Figures 22 and 23. In some embodiments, the side panel 3015 is provided with an inspection window 30151. At least one of the first housing 11 and the second housing 21 includes an inspection plate 3016 covering the inspection window 30151. A portion of the inspection plate 3016 is stacked with the bending portion 30142. The handle 3020 is connected to the inspection plate 3016.

[0194] Thus, the bent portion 30142 of the top plate 3014, the side plate 3015, and the inspection plate 3016 are stacked to form a three-layer plate structure. The upper end 3011 of at least one of the first housing 11 and the second housing 21 includes this three-layer plate structure. The handle 3020 is installed on the three-layer plate structure. That is to say, the inspection plate 3016 can further increase the thickness of the upper end 3011, thereby improving the reliability of the handle 3020 during use.

[0195] Specifically, the inspection window 30151 penetrates the side panel 3015, allowing observation of the internal structure of at least one of the first housing 11 and the second housing 21. For example, if a sensor is installed inside at least one of the first housing 11 and the second housing 21, the sensor can be maintained through the inspection window 30151. The inspection plate 3016 covers the inspection window 30151, thereby reducing the entry of foreign objects into at least one of the first housing 11 and the second housing 21 and improving the operational stability of the indoor unit 100.

[0196] Referring to Figure 23, in some embodiments, a handle 3020 is sequentially inserted through the handle 3020, the access plate 3016, the side plate 3015, and the bent portion 30142 at the upper end 3011 via a first fastener 3030. The handle 3020 is fixedly connected to the access plate 3016 via a second fastener 3040. Thus, during the disassembly of the access plate 3016, the handle 3020 can be held, making the access plate 3016 easier to disassemble.

[0197] Specifically, the first fastener 3030 can be, for example, a screw. When the first fastener 3030 is removed, the access plate 3016 can be removed from the side plate 3015. The second fastener 3040 can be a screw or a rivet, which secures the handle 3020 to the access plate 3016. During the removal of the access plate 3016, the handle 3020 remains fixed to the access plate 3016. This not only facilitates the removal of the access plate 3016 but also reduces the risk of the handle 3020 being lost after it becomes detached from the access plate 3016.

[0198] Of course, in other embodiments, the handle 3020 can be fixedly connected to the inspection plate 3016 by welding or other means.

[0199] Please refer to Figures 24 and 27. The indoor unit 100 of the air conditioner shown in Figure 27 omits the handle 3020. In some embodiments, the first housing 11 and the second housing 21 are interconnected. The indoor unit 100 of the air conditioner also includes a fan 3050 and a heat exchanger 151. The fan 3050 is disposed in the second housing 21, and the heat exchanger 151 is disposed in the first housing 11. Both the first housing 11 and the second housing 21 are provided with handles 3020.

[0200] Thus, the air conditioner indoor unit 100 is divided into two parts, which makes it easier to move the air conditioner indoor unit 100. Both the first box 11 and the second box 21 are equipped with handles 3020, so that both the first box 11 and the second box 21 can be moved through the handles 3020, thereby facilitating the transportation and installation of the air conditioner indoor unit 100.

[0201] Specifically, the structures of the first housing 11 and the second housing 21 can be different. For example, the first housing 11 may be provided with an inspection panel 3016, while the side panel 3015 of the second housing 21 may not have an inspection window 30151.
