[0049] For ease of description, the length direction of the indoor unit, the length direction of the evaporator, and the length direction of the casing in this application are all... Figure 1 The directions mentioned in M ​​refer to the width direction of the indoor unit, the width direction of the casing, and the width direction of the evaporator. Figure 1 The direction indicated by N in this application. The vertical direction in this application is as follows: Figure 2 As shown, the vertical direction refers to the up-and-down direction.

[0050] Combination Figures 1 to 24As shown, this disclosure provides an air conditioner, particularly an embedded air conditioner.

[0051] The embedded air conditioner includes an indoor unit, which includes a housing 70, an evaporator 10, and a fan 77. The housing 70 is provided with an air inlet 75 and an air outlet 76. The evaporator 10 and the fan 77 are located inside the housing 70. The fan 77 can drive the airflow flowing in through the air inlet 75 to exchange heat with the evaporator 10 and then flow out through the air outlet 76.

[0052] Optionally, both the air inlet 75 and the air outlet 76 are located on the bottom wall of the housing 70, so that the embedded air conditioner can draw in and vent air from the same side.

[0053] Optionally, one end of the evaporator 10 along its length forms a receiving cavity 74 with the housing 70, and the connecting pipe assembly 20 connected to the evaporator 10 is located inside the receiving cavity 74.

[0054] Optionally, the evaporator 10 includes a first end 18 and a second end 19 disposed opposite each other along the length direction, wherein the first end 18 and the housing 70 enclose a receiving cavity 74, and the connecting pipe assembly 20 is located on one side of the first end 18 and is connected to the evaporator 10.

[0055] Optionally, such as Figure 2 As shown, the evaporator 10 includes a first heat exchange section 15 and a second heat exchange section 16. The second heat exchange section 16 is connected to the first heat exchange section 15 and forms an angle with the opening facing upwards. Thus, the evaporator 10 is a multi-section heat exchanger.

[0056] Optionally, the heat exchange area of ​​the first heat exchange section 15 is larger than the heat exchange area of ​​the second heat exchange section 16.

[0057] Optionally, along the circumference of the evaporator 10, the length of the first heat exchange section 15 is greater than the length of the second heat exchange section 16.

[0058] This disclosure provides an evaporator assembly, such as... Figures 5 to 8 As shown, the evaporator assembly includes an evaporator 10 and a connecting pipe assembly 20. The evaporator 10 is provided with a first air port 11. The connecting pipe assembly 20 includes a gas collecting pipe 21 and a connecting pipe assembly that is directly or indirectly connected to the gas collecting pipe 21. The gas collecting pipe 21 is located along the length of the evaporator 10 (e.g., along the length of the evaporator 10). Figure 1 The gas collection pipe 21 is located on one side of the direction shown in the middle M, and is adapted to connect the first gas port 11 and the compressor; wherein, the gas collection pipe 21 extends in the vertical direction, and the connecting pipe group is arranged to converge towards the gas collection pipe 21.

[0059] In this embodiment, the gas collector pipe 21 of the connecting pipe assembly 20 is used for the inflow of external gaseous refrigerant into the evaporator 10, or for the outflow of gaseous refrigerant from the evaporator 10 through the gas collector pipe 21. The gas collector pipe 21 is vertically arranged, and the connecting pipe assembly converges towards the gas collector pipe 21. This reduces the horizontal displacement of the connecting pipe assembly 20, that is, in the width direction of the evaporator 10 (e.g., ...). Figure 1 The space occupied by the N-direction (as shown in the middle) can be reduced, thus reducing the space occupied by the connecting pipe assembly 20, and further saving space on one side of the evaporator 10 along its length. This allows for better layout of wiring and other components, such as components, water pumps, and wiring harnesses. It also solves the problem of the gas collecting pipe 21 and connecting pipe assembly occupying too much space, reduces interference between components and between components and the connecting pipe assembly 20, and facilitates the disassembly of the evaporator, improving disassembly convenience and thus improving maintenance convenience.

[0060] It can be understood that the "converged arrangement" in this application refers to the connection pipe assembly being positioned close to the gas collecting pipe 21. In other words, the connection pipe assembly is located within the space surrounding the gas collecting pipe 21, and the distance between the connection pipe assembly and the gas collecting pipe 21 is the minimum allowable distance between them. This reduces the space occupied by the connecting pipe assembly 20 in the width direction of the evaporator 10, facilitating the placement of other components. Furthermore, the "converged arrangement" in this application also refers to the connection pipe assembly being able to bend or tilt towards the gas collecting pipe 21 to further reduce the distance between them, saving even more space.

[0061] Optionally, the connecting pipe assembly includes a connecting gas pipe 22 and / or a liquid pipe assembly, wherein the connecting gas pipe 22 connects the gas collecting pipe 21 to the second gas port 12 of the evaporator 10, and the liquid pipe assembly is adapted to connect the liquid port 13 of the evaporator 10 and the throttling device.

[0062] In this embodiment, the connecting pipe assembly can be a connecting gas pipe 22 that is directly connected to the gas collecting pipe 21, or it can be a liquid pipe assembly that is indirectly connected to the gas collecting pipe 21 through the evaporator 10. The connecting pipe assembly 20 of the evaporator 10 is arranged on the same side of the length direction of the evaporator 10, and the other pipe assemblies of the connecting pipe assembly 20 are all gathered towards the gas collecting pipe 21. This can reduce the space occupied by the connecting pipe assembly 20 as a whole and improve the rationality of the layout of the components in the housing 70.

[0063] It should be noted that the gas collecting pipe 21 extends vertically, but this does not mean that the angle between the gas collecting pipe 21 and the vertical direction is strictly 0°. Depending on the installation model and the installation space, the gas collecting pipe 21 may be slightly inclined in the vertical direction, which can also be regarded as the gas collecting pipe 21 extending vertically. Compared with the horizontally placed second connection pipe group 80 in related technologies, the scheme of setting the gas collecting pipe 21 vertically is an optional embodiment of this application.

[0064] Optionally, the angle between the gas collecting pipe 21 and the vertical direction is greater than or equal to 0° and less than or equal to 45°. It can be understood that: along the length direction of the evaporator 10, the angle between the projection of the end face of the gas collecting pipe 21 on the length direction of the evaporator 10 and the vertical direction is greater than or equal to 0° and less than or equal to 45°.

[0065] In this embodiment, the angle between the gas collecting pipe 21 and the vertical direction is greater than or equal to 0° and less than or equal to 45°. Thus, the main body of the gas collecting pipe 21 extends vertically, and even if the gas collecting pipe 21 has a certain degree of inclination, the angle between the gas collecting pipe 21 and the vertical direction will not exceed 45°. This ensures that the space occupied by the gas collecting pipe 21 in the width direction of the evaporator 10 is reduced. Compared to the prior art, such as... Figure 4 As shown, in the scheme where the second gas collecting pipe 81 is placed horizontally (the second gas collecting pipe 81 extends along the width direction of the evaporator 10), the second connecting pipe assembly 80 occupies a relatively large space in the width direction of the evaporator 10. In this embodiment, the space occupied by the gas collecting pipe 21 in the width direction of the evaporator 10 is reduced, saving space on one side of the evaporator 10 in the length direction. This means reducing the space occupied by the gas collecting pipe 21 in the receiving cavity 74 along the width direction of the indoor unit. This increases the space of the receiving cavity 74, thereby improving the layout of wiring and other components inside the casing 70, increasing the ease of disassembly, and ultimately improving the convenience of maintenance.

[0066] Optionally, the angle between the gas collecting pipe 21 and the vertical direction is greater than or equal to 0° and less than or equal to 30°. This can be understood as the angle between the projection of the end face of the gas collecting pipe 21 along the length of the evaporator 10 and the vertical direction being greater than or equal to 0° and less than or equal to 30°.

[0067] In this embodiment of the present disclosure, when the angle between the gas collecting pipe 21 and the vertical direction is between 0 and 30°, the space occupied by the gas collecting pipe 21 in the width direction of the evaporator 10 can be further reduced, thereby further saving the space of the receiving cavity 74.

[0068] Optionally, the angle between the gas collecting pipe 21 and the vertical direction is 0°. That is, along the length of the evaporator 10, the projection of the end face of the gas collecting pipe 21 on the length of the evaporator 10 extends in the vertical direction.

[0069] In this embodiment, the angle between the gas collecting pipe 21 and the vertical direction is 0°, so that the gas collecting pipe 21 occupies only the space of one vertical plane in the width direction of the evaporator 10, which can save the space in the receiving cavity 74 to the greatest extent.

[0070] Optionally, such as Figure 7As shown, the air collection pipe 21 includes a first air collection pipe section 211, a second air collection pipe section 212, and a third air collection pipe section 213 connected in sequence. The first air collection pipe section 211 connects the compressor and the second air collection pipe section 212. The first air collection pipe section 211 extends from the outside of the housing 70, through the housing 70, and into the receiving cavity 74, extending along the length of the indoor unit. The third air collection pipe section 213 connects the second air collection pipe section 212 and the first air inlet 11, extending along the length of the indoor unit and towards the first air inlet 11 to achieve the connection between the air collection pipe 21 and the first air inlet 11. The second air collection pipe section 212 extends vertically, which reduces the space occupied by the air collection pipe section 21 in the width direction of the indoor unit, facilitating the installation and wiring of other components and making maintenance easier.

[0071] Optionally, the second gas collecting pipe section 212 is straight, which can further reduce the space occupied by the second gas collecting pipe section 212 in the width direction of the evaporator 10.

[0072] Optionally, the first gas collecting tube segment 211 and / or the second gas collecting tube segment 212 are both straight.

[0073] Optionally, a bend is formed at the connection between the first gas collecting pipe section 211 and the second gas collecting pipe section 212 to facilitate the flow of gaseous refrigerant and reduce resistance.

[0074] Optionally, a bend is formed at the connection between the second gas collecting pipe section 212 and the third gas collecting pipe section 213 to facilitate the flow of gaseous refrigerant and reduce resistance.

[0075] Optionally, along the length of the evaporator 10, the projections of the end faces of the first gas collecting pipe section 211, the second gas collecting pipe section 212, and the third gas collecting pipe section 213 in the direction of the evaporator 10 are on the same vertical line, thus achieving an angle of 0° between the gas collecting pipe 21 and the vertical direction, saving space in the receiving cavity 74 to the greatest extent.

[0076] Optionally, when the first air inlet 11 and the first air collecting pipe section 211 are not on the same vertical plane, the second air collecting pipe section 212 can be set at an angle. That is, the air collecting pipe 21 has an angle with the vertical direction, but the angle is within the range mentioned above. This can ensure the connection between the air collecting pipe 21 and the first air inlet 11, and also minimize the space occupied by the air collecting pipe 21.

[0077] Optionally, the first air inlet 11 is located at the connection between the first heat exchange section 15 and the second heat exchange section 16, and the air collecting pipe 21 extends upward from the first air inlet 11.

[0078] In this embodiment, the evaporator 10 is a multi-stage heat exchanger. The first gas port 11 is located at the connection between the first heat exchange section 15 and the second heat exchange section 16. The first gas port 11 is located at the V-shaped connection, which allows the refrigerant to be distributed more evenly to the two heat exchange sections, solving the problem of frost imbalance caused by uneven gas-liquid distribution in traditional L-shaped evaporators. The first gas port 11 is located at the bottom of the evaporator 10, so there is a height difference between the first gas collecting pipe section 211 and the first gas port 11. The gas collecting pipe 21 passes through the shell 70 and enters the receiving cavity 74, then extends downward in a vertical direction. This ensures the connection space between the gas collecting pipe 21 and the evaporator 10 and saves space.

[0079] Optionally, such as Figure 6 and Figure 7 As shown, the evaporator 10 is also provided with a second air port 12. The connecting pipe assembly includes a connecting air pipe 22, which is connected between the gas collecting pipe 21 and the second air port 12. When the connecting pipe assembly includes the connecting air pipe 22, the connecting air pipe 22 is connected between the second gas collecting pipe section 212 and the second air port 12 of the evaporator 10. The connecting air pipe 22 is located on one or both sides of the gas collecting pipe 21 along the width direction of the evaporator 10, and the connecting air pipe 22 converges towards the gas collecting pipe 21.

[0080] In this embodiment, connecting pipes 22 are led out from one or both sides of the gas collecting pipe 21. The connecting pipes 22 connect the evaporator 10 and the gas collecting pipe 21, and can increase the inflow or outflow of gaseous refrigerant in the evaporator 10. The connecting pipes 22 converge toward the gas collecting pipe 21, that is, the connecting pipes 22 are inclined or bent toward the gas collecting pipe 21. Compared with the horizontally bent structure, this can further reduce the space occupied by the connecting pipe assembly 20 and ensure the gas inflow or outflow of the evaporator 10.

[0081] Optionally, when there are multiple connecting air pipes 22, at least two connecting air pipes 22 are arranged sequentially at intervals along the height direction of the second gas collecting pipe section 212.

[0082] In this embodiment of the present disclosure, multiple connecting gas pipes 22 are spaced apart along the height direction of the second gas collecting pipe section 212, which can form a gradient flow of gaseous refrigerant, ensure the distribution of refrigerant, and at the same time eliminate eddies and reduce noise.

[0083] Optionally, the heat exchange area of ​​the first heat exchange section 15 is larger than that of the second heat exchange section 16, the second air inlets 12 are all located at the upper part of the thickness direction of the first heat exchange section 15, and the connecting air pipe 22 is located on the side of the air collecting pipe 21 facing the first heat exchange section 15.

[0084] In this embodiment of the present disclosure, the heat exchange area of ​​the first heat exchange section 15 is larger than that of the second heat exchange section 16. Therefore, a second air port 12 and a connecting air pipe 22 are provided in the first heat exchange section 15, which can increase the inflow or outflow of gaseous refrigerant in the first heat exchange section 15, thereby ensuring the temperature uniformity and balance of the first heat exchange section 15 and the second heat exchange section 16.

[0085] Optionally, such as Figures 6 to 8 As shown, the evaporator 10 also includes a liquid inlet 13, and the connecting pipe assembly 20 also includes a liquid pipe assembly, which is adapted to connect the liquid inlet 13 and the throttling device; wherein, the connecting gas pipe 22 and the gas collecting pipe 21 define an installation space 26, the installation space 26 is located on the side of the connecting gas pipe 22 facing the first gas collecting pipe section 211, and the liquid pipe assembly is located within the installation space 26.

[0086] In this embodiment, since the gas collecting pipe 21 is arranged vertically and the connecting pipe 22 converges toward the gas collecting pipe 21, the space occupied by the gas collecting pipe 21 and the connecting pipe 22 in the width direction of the evaporator 10 is reduced. The installation space 26 is cleared on one side of the gas collecting pipe 21 and the connecting pipe 22, and the liquid pipe assembly is located in the installation space 26. In this way, the liquid pipe assembly can also be set close to the gas collecting pipe 21, which can further reduce the space occupied by the connecting pipe assembly 20, so that the receiving cavity 74 can save more space in the width direction of the indoor unit, which is convenient for setting up other components or wiring, and improves the convenience of installation and maintenance.

[0087] Optionally, there are multiple liquid inlets 13, and the liquid pipe group includes a liquid collecting pipe 23, liquid branch pipes 24, and a liquid distributor 25. One end of the liquid collecting pipe 23 is adapted to be connected to a throttling device; one end of the liquid branch pipes 24 is connected to the liquid inlet 13, and the number of liquid branch pipes 24 is the same as the number of liquid inlets 13 and corresponds one-to-one; the liquid distributor 25 is connected between the other end of the liquid collecting pipe 23 and the other ends of the multiple liquid branch pipes 24; wherein, the liquid distributor 25 is located in the installation space 26, and the liquid distributor 25 is located between the liquid collecting pipe 23 and the gas collecting pipe 21.

[0088] In this embodiment, the liquid separator 25 is located between the liquid collecting pipe 23 and the gas collecting pipe 21, and is located within the installation space 26. Since the liquid separator 25 converges toward the gas collecting pipe 21, the liquid collecting pipe 23 and the liquid branch pipe 24 connected to the liquid separator 25 also converge toward the gas collecting pipe 21. This allows the liquid pipe assembly to be set as close as possible to the gas collecting pipe 21, saving other space.

[0089] Optionally, in the width direction of the evaporator 10, the distance between the distributor 25 and the gas collecting pipe 21 is less than the distance between the distributor 25 and the end of the evaporator 10 in the width direction. Optionally, in the width direction of the evaporator 10, the distance between the distributor 25 and the gas collecting pipe 21 is less than the distance between the distributor 25 and the end of the first heat exchange section 15 away from the second heat exchange section 16.

[0090] In this embodiment, since the liquid distributor 25 is connected to both the liquid collecting pipe 23 and the liquid branch pipe 24, the liquid distributor 25 is positioned close to the gas collecting pipe 21. This allows the entire liquid pipe assembly to be positioned closer to the gas collecting pipe 21, saving more space.

[0091] Optionally, the heat exchange area of ​​the first heat exchange section 15 is greater than the heat exchange area of ​​the second heat exchange section 16, the liquid outlet 13 is located at the lower part of the thickness direction of the heat exchange section, and the number of liquid outlets 13 in the first heat exchange section 15 is greater than or equal to the number of liquid outlets 13 in the second heat exchange section 16.

[0092] In this embodiment of the present disclosure, the heat exchange area of ​​the first heat exchange section 15 is larger than that of the second heat exchange section 16. Therefore, the number of liquid inlets 13 in the first heat exchange section 15 is greater than that in the second heat exchange section 16, which can ensure the refrigerant flow rate of the first heat exchange section 15 and thereby improve the heat exchange uniformity of the first heat exchange section 15 and the second heat exchange section 16.

[0093] Optionally, the distributor 25 extends vertically, with the collecting pipe 23 connected to the lower part of the distributor 25 and a branch pipe of the collecting pipe 23 connected to the upper part of the distributor 25. This makes the structure of the liquid pipe assembly more compact, thus freeing up more space in the receiving cavity 74.

[0094] Optionally, the liquid collecting pipe 23 and / or the liquid branch pipe 24 are both bent toward the direction of the gas collecting pipe 21, or at least a portion of the vertical extension of the liquid collecting pipe 23 and / or the liquid branch pipe 24 is a straight segment.

[0095] In this embodiment of the present disclosure, the liquid collecting pipe 23 and / or the liquid branch pipe 24 are both bent toward the direction of the gas collecting pipe 21, such as Figure 7 As shown, the liquid branch pipe 24 connects the distributor 25 and the liquid outlet 13. While ensuring connectivity between the liquid outlet 13 and the distributor 25, the liquid branch pipe 24 bends towards the gas collecting pipe 21 to minimize the space occupied by the liquid branch pipe 24 in the width direction of the evaporator 10. This causes the liquid collecting pipe 23 and / or the liquid branch pipe 24 to converge towards the gas collecting pipe 21, improving space-saving efficiency. Alternatively, at least a portion of the vertical extension of the liquid collecting pipe 23 and / or the liquid branch pipe 24 is a straight section. This prevents the liquid collecting pipe 23 and / or the liquid branch pipe 24 from extending away from the gas collecting pipe 21, except for necessary connections, further reducing the space occupied in the receiving cavity 74.

[0096] Optionally, the distance between the liquid collecting pipe 23 and the end of the first heat exchange section 15 furthest from the second heat exchange section 16 is greater than the distance between the liquid collecting pipe 23 and the distributor 25. This allows the liquid collecting pipe 23 to be closer to the distributor 25, and since the distributor 25 is close to the gas collecting pipe 21, the liquid collecting pipe 23 is also closer to the gas collecting pipe 21.

[0097] Optionally, such as Figure 5 As shown, the housing 70 includes a first side plate 71 and a second side plate 72, the first side plate 71 being located in the width direction of the housing 70 (e.g., ...). Figure 1 The second side plate 72 is located on one side of the direction shown in the middle (N), and is located in the length direction of the housing 70 (e.g., in the direction shown in the middle N). Figure 1 On one side (as shown in direction M), the second side plate 72 corresponds to the first end 18 of the evaporator 10, the first side plate 71 is connected to the second side plate 72, and the receiving cavity 74 is located between the second side plate 72 and the first end 18. Therefore, the second side plate 72 forms a side wall of the receiving cavity 74 along the length direction of the indoor unit, and the first side plate 71 forms a side wall along the width direction of the indoor unit.

[0098] Optionally, the first side plate 71 is closer to the first heat exchange section 15.

[0099] Optionally, the distance between the liquid collecting pipe 23 and the first side plate 71 is greater than or equal to the distance between the liquid collecting pipe 23 and the gas collecting pipe 21, which also makes the liquid collecting pipe 23 closer to the gas collecting pipe 21, saving space in the width direction of the receiving cavity 74.

[0100] This disclosure also provides an indoor unit, such as... Figures 9 to 15 As shown, the indoor unit includes a housing 70, an evaporator assembly, and a detection device 30. The evaporator assembly includes an evaporator 10 and a connecting pipe assembly 20. The evaporator assembly is located inside the housing 70. One end of the evaporator 10 along the length direction of the indoor unit (i.e., the first end 18) and the housing 70 enclose a receiving cavity 74. The connecting pipe assembly 20 is connected to the evaporator 10 and is located inside the receiving cavity 74. The detection device 30 is located on the side wall of the receiving cavity 74 along the width direction of the indoor unit. The detection device 30 is used to detect refrigerant leakage in the evaporator assembly.

[0101] In this embodiment, the detection device 30 is disposed within the receiving cavity 74, which houses the connecting pipe assembly 20, which serves as the inlet and outlet pipes of the evaporator 10. Therefore, the receiving cavity 74 is the area with the densest pipe welding. The detection device 30 can accurately and sensitively detect refrigerant leakage in the evaporator assembly, thereby improving the safety of air conditioning use and ensuring user safety. Furthermore, since multiple components, such as the connecting pipe assembly 20 or a water pump, need to be installed on the side wall of the receiving cavity 74 along the length of the indoor unit, placing the detection device 30 on the side wall of the receiving cavity 74 along the width of the indoor unit effectively detects refrigerant leakage while avoiding interference between the detection device 30 and other components, thus preventing interference with the disassembly and assembly of the evaporator assembly and other components, and improving the convenience of disassembly, assembly, and maintenance.

[0102] Optionally, the connection pipe assembly 20 of the indoor unit adopts the aforementioned connection pipe assembly, which increases the space of the housing cavity in the width direction of the indoor unit, thereby providing sufficient space to install a detection device on the side wall in the width direction of the indoor unit, improving the detection accuracy of refrigerant leakage.

[0103] Optionally, such as Figures 13 to 15 As shown, the housing 70 includes a first side plate 71, which is located on one side of the indoor unit in the width direction. The detection device 30 is located on the side of the first side plate 71 facing the receiving cavity 74. The indoor unit also includes a mounting bracket 31, and the detection device 30 is located on the mounting bracket 31. The mounting bracket 31 is detachably connected to the first side plate 71.

[0104] In this embodiment, the detection device 30 is mounted on the first side plate 71 via a mounting bracket 31. This allows for maintenance of the detection device 30 without disassembling the housing 70, evaporator 10, water pump, or other components; only the mounting bracket 31 needs to be removed. This ensures the detection device 30 is in the optimal detection position while avoiding the occupation of other functional space. The detachable mounting bracket 31 also reduces maintenance complexity, allowing for individual maintenance or replacement of the detection device 30 without disassembling the entire housing 70.

[0105] Optionally, such as Figure 13 As shown, the mounting bracket 31 has a buckle 32 on the side facing the first side plate 71. The buckle 32 extends vertically, and the first side plate 71 has a locking hole 33. The buckle 32 can be inserted into or removed from the locking hole 33 in the vertical direction.

[0106] In this embodiment, the vertical insertion and removal structure of the latch 32 and the locking hole 33 significantly improves the efficiency of assembly and disassembly. The vertical operation is suitable for scenarios with limited space, such as embedded air conditioners, where fixing or disassembly can be completed simply by pushing in / out vertically, without the need for tools. The extended design of the latch 32 ensures sufficient insertion depth, providing stable mechanical locking force and preventing the detection device 30 from shifting due to vibration. Furthermore, the design of the latch 32 and the locking hole 33 reduces the difficulty and time required for assembly and disassembly, while avoiding problems such as stripped threads and loss caused by repeated screw removal and assembly, thus improving on-site maintenance efficiency.

[0107] Optionally, such as Figure 14 and Figure 15 As shown, the latch 33 penetrates the first side plate 71. The first side plate 71 along the vertical direction of the latch 33 is constructed with an inclined wall 331. Along the insertion direction of the latch 32, the inclined wall 331 is inclined away from the receiving cavity 74. When the latch 32 is located in the latch 33, the latch 32 is located on the side of the inclined wall 331 away from the receiving cavity 74. And / or, when the latch 32 is located in the latch 33, the end of the inclined wall 331 facing the latch 33 abuts against the vertical end of the mounting bracket 31.

[0108] In this embodiment, the inclined wall 331 at the edge of the latch 33 acts as a guide during the insertion of the latch 32, allowing the latch 32 to smoothly enter the latch 33 and automatically align itself. Once the latch 32 is fully inserted, the inclined wall 331 abuts against the end of the mounting bracket 31, forming a mechanical limit and preventing the detection device 30 from wobbling into the receiving cavity 74. This ensures stable positioning of the detection device 30 and avoids false alarms or detachment due to vibration, further improving reliability.

[0109] Optionally, the bottom of the mounting bracket 31 is provided with a first screw hole 34, and the first side plate 71 is provided with a second screw hole 341. Fasteners pass through the first screw hole 34 and the second screw hole 341 to connect the mounting bracket 31 and the first side plate 71.

[0110] In this embodiment, the latch 32 bears the main positioning and load-bearing functions, while the screw provides anti-loosening and anti-dislodgement protection, ensuring that the detection device 30 will not accidentally fall off even during long-term operation and vibration. This addresses high-vibration conditions. After the latch 32 completes its initial positioning, the screw penetrates the bracket and side plate to provide rigid constraint, preventing slight loosening due to wear of the latch 32 after long-term use. Furthermore, disassembly only requires loosening the screw on one side of the mounting bracket 31 to remove the latch 32, balancing both robustness and convenience.

[0111] Optionally, such as Figures 11 to 15 As shown, the mounting bracket 31 is also constructed with a cable tray 35, which is used to store the cable harness 36 (hereinafter referred to as the first cable harness 36 for easy distinction).

[0112] In this embodiment, the wiring inside the receiving cavity 74 is relatively dense, with sensor wiring harnesses such as those for water pumps, floats, and evaporator coils passing through. If these wiring harnesses cannot be effectively stored, they will block the detection port of the detection device 30 for the refrigerant, which will affect the detection accuracy. The mounting bracket 31 is provided with a wiring groove 35, which effectively stores the first wiring harness 36 inside the receiving cavity 74 and offsets it from the detection port of the detection device 30. This not only effectively stores the wiring harness but also does not affect the detection accuracy.

[0113] Optionally, the first wiring harness 36 is electrically connected to at least one of the coils of the water pump, the float, and the evaporator.

[0114] Optionally, the mounting bracket 31 includes a mounting bracket body, a connecting plate 351, and a wiring plate 352. The mounting bracket defines a mounting groove 37, and the detection device 30 is disposed in the mounting groove 37. The connecting plate 351 is disposed at the bottom of the mounting groove 37 and extends downward. The wiring plate 352 is disposed at the bottom of the mounting groove 37 and extends downward. The wiring plate 352 is located on the side of the connecting plate 351 facing the receiving cavity 74, and the wiring plate 352 and the connecting plate 351 enclose a wiring groove 35.

[0115] In this embodiment, the mounting groove 37 provides a precise mounting reference for the detection device 30. A wiring groove 35 is formed between the connecting plate 351 and the wiring plate 352. The first wire harness 36 is bidirectionally limited within the wiring groove 35, preventing it from overflowing and avoiding damage during assembly. Furthermore, the mounting bracket 31 simultaneously performs fixing, positioning, and wiring functions, reducing the number of parts and improving assembly efficiency. Additionally, the wiring groove 35 is located at the bottom of the mounting groove 37, ensuring that the first wire harness 36 remains within it without interfering with the mounting groove 37. This prevents interference between the wire harness and the detection port of the detection device 30 (i.e., the opening of the mounting groove 37), thus guaranteeing the detection accuracy of the detection device 30.

[0116] Optionally, the detection device and the mounting bracket can be detachably connected to facilitate the replacement of the detection device.

[0117] Optionally, such as Figure 12 As shown, the lower end of the wiring board 352 is constructed with a limiting protrusion 353, and the limiting protrusion 353 protrudes towards the wiring groove 35. In this embodiment, the limiting protrusion 353 at the lower end of the wiring board 352 forms a "barbed" type opening, so that once the first wire harness 36 is inserted into the wiring groove 35, it is not easy to fall out; and the limiting protrusion 353 protrudes towards the groove, so it will not occupy additional external space, ensuring that the other components of the receiving cavity 74 still have sufficient assembly clearance, thus taking into account both the reliability of cable management and the compactness of the structure.

[0118] Optionally, the housing 70 includes a panel with an air inlet 75 and an air outlet 76, which are arranged along the width direction of the indoor unit; wherein, the detection device 30 is located on the side wall of the receiving cavity 74 away from the air outlet 76.

[0119] In this embodiment, the detection device 30 is located on the side wall of the receiving cavity 74 away from the air outlet 76, that is, the detection device 30 is close to the air inlet 75. In this way, the leaked refrigerant can be carried to the detection device 30 by the return airflow of the air inlet 75 as soon as possible. The leaked refrigerant is actively adsorbed by the negative pressure environment of the air inlet area when the air conditioner is running, which greatly improves the detection rate of trace leaks and shortens the response time. At the same time, this position is usually far away from the high humidity and high temperature area of ​​the air outlet 76, which can reduce the interference of ambient temperature and humidity on the detection device 30, improve the detection accuracy and extend the service life of the detection device 30.

[0120] Optionally, the panel is the bottom wall of the housing.

[0121] like Figures 16 to 24 As shown, the evaporator 10 also includes a tube sheet located at the end of the evaporator 10 along its length.

[0122] like Figures 16 to 18As shown, this embodiment of the present disclosure provides a tube sheet for an evaporator (hereinafter referred to as the first tube sheet 40 for easy distinction), the first tube sheet 40 having a mounting part 41; wherein, the mounting part 41 is used to mount one or more of the detection module 47 and the sterilization module 48.

[0123] In this embodiment, the first tube sheet 40 of the evaporator 10 is provided with a mounting part 41, so that the detection module 47 (such as a sensor) or sterilization module 48 required by the air conditioner can be installed on the first tube sheet 40 of the evaporator 10. In this way, the sensor is set up in a more centralized manner. Since the airflow in the air conditioner needs to flow through the evaporator 10, installing the sensor on the first tube sheet 40 can also ensure the detection and sterilization of the air conditioning airflow. This not only improves the installation convenience of various sensor modules, but also ensures the detection and sterilization effect. Moreover, integrating multiple sensors into the first tube sheet 40 also facilitates disassembly and maintenance, improving the ease of disassembly and assembly of the air conditioner.

[0124] Furthermore, a mounting section 41 is constructed on the first tube sheet 40, allowing the detection module 47 and the sterilization module 48 to share the same bearing interface. This eliminates the need for separate brackets or openings for these two types of components inside the air conditioner, transforming the overall layout from dispersed to centralized. Monitoring and sterilization along the airflow path are achieved in one step. Additionally, the assembly steps on the air conditioner production line are reduced. During later maintenance, only one section of the first tube sheet 40 needs to be removed to simultaneously inspect or replace the detection module 47 and the sterilization module 48, significantly shortening downtime and reducing labor costs.

[0125] Optionally, the detection module 47 includes a temperature sensor and / or a humidity sensor; and / or, the sterilization device includes a UVC sterilization module.

[0126] In this embodiment, the detection module 47 is a temperature sensor and / or a humidity sensor, enabling it to acquire the temperature or humidity of the airflow at the vent in real time, thus achieving precise temperature and humidity control for the air conditioner. The sterilization module 48 is a UVC (short-wave ultraviolet) sterilization module. The UVC sterilization module uses short-wave ultraviolet light to kill bacteria, viruses, mold, and other microorganisms. It offers fast sterilization, energy savings, and a stable sterilization effect, thereby ensuring the optimal performance of the air conditioner.

[0127] Optionally, the mounting part 41 is located at the end of the first tube sheet facing the air outlet to improve the effectiveness of the detection module and / or sterilization module. Here, the air outlet can be either an air inlet or an air outlet.

[0128] Optionally, the first tube sheet 40 includes a first end plate 44 and a second end plate 45. The second end plate 45 is disposed opposite to the first end plate 44 and encloses a heat exchange cavity. The heat exchange cavity is used to place the heat exchange tubes of the evaporator (i.e., the coils of the evaporator). Specifically, the heat exchange cavity is used to place the ends of the heat exchange tubes. The first end plate 44 is located on the side of the second end plate 45 facing the air outlet, and the mounting part 41 is disposed on the side of the first end plate 44 away from the heat exchange cavity.

[0129] In this embodiment, the mounting part 41 is disposed on the outer side of the first end plate 44 away from the heat exchange cavity, that is, on the windward side of the first end plate 44. This allows the detection module 47 and the sterilization module 48 to be directly exposed in the main airflow path into the evaporator, ensuring optimal detection and sterilization effects. Secondly, mounting the modules outside the heat exchange cavity effectively isolates them from condensate, thermal shock, and the complex tube bundle environment that may exist inside the heat exchange cavity, protecting the various modules from adverse environmental influences and improving their operational reliability and lifespan.

[0130] Optionally, the installation part 41 includes a first installation part 42, which is used to install different types of sterilization modules 48.

[0131] In this embodiment, a first mounting part 42 is provided for mounting different types of sterilization modules 48. This makes the first mounting part 42 versatile, greatly enhancing the compatibility and flexibility of the first tube sheet 40. It allows for the selection and combination of sterilization devices with different technologies according to specific needs, thereby improving the flexibility of mounting the sterilization modules 48.

[0132] Optionally, there may be multiple first mounting parts 42, so that when multiple sterilization modules have different mounting interfaces, they can be installed in different first mounting parts 42.

[0133] Optionally, the sterilization module 48 includes various types of UVC sterilization modules, such as UVC sterilization module, UVCpro sterilization module, and UVCplus sterilization module. All three types of sterilization modules 48 can be installed in the first mounting part 42.

[0134] Optionally, the mounting part 41 includes a second mounting part 43, which is used to mount the detection module 47; wherein the second mounting part 43 is engaged with the detection module 47.

[0135] In this embodiment, a second mounting part 43 for the detection module 47 is separately provided and a snap-fit ​​method is adopted, which optimizes the installation of the detection module 47, making the installation and disassembly process of the detection module 47 fast, simple and reliable, avoiding complicated wiring or screw fixing, and improving the convenience of maintenance of the detection module 47.

[0136] Optionally, the first tube sheet 40 further includes a baffle 46 and a support rib 461. The baffle 46 is located on the side of the first end plate 44 facing the evaporator. The baffle 46 and the support rib 461 enclose an accommodating space 462. The first mounting part 42 is located within the accommodating space 462. When the sterilization module 48 is installed in the first mounting part 42, the support rib 461 and the baffle 46 are adapted to abut against the sterilization module 48.

[0137] In this embodiment, the baffle 46 and the support rib 461 together enclose the accommodating space 462 and abut against the sterilization module 48, providing stable physical support and positioning for the sterilization module 48, enhancing its ability to resist vibration and impact, providing stable mechanical limit and suppressing operating resonance, and ensuring stability in the air-conditioned operating environment.

[0138] Optionally, the first tube sheet 40 is further provided with a positioning post 423, which is located on one side of the first mounting part 42 and is used for positioning and connecting with the sterilization module 48. The positioning post 423 enables the sterilization module 48 to be quickly and accurately pre-positioned, simplifying the installation and alignment process.

[0139] Optionally, the first mounting part 42 includes a connecting hole 421 and a copper nut 422, the copper nut 422 being embedded in the connecting hole 421 and used to connect with the sterilization module 48.

[0140] In this embodiment, the first tube sheet 40 is made of PP with added glass fiber to increase its hardness, but this may result in poor toughness and brittleness. The first mounting part 42 uses an inlaid copper nut 422, which can effectively prevent thread slippage and ensure a secure fixation. Moreover, compared to directly tapping the first tube sheet 40, it provides a more durable, corrosion-resistant threaded connection interface that can withstand greater tightening torque, greatly improving the mechanical strength and long-term reliability of the sterilization module 48 installation.

[0141] Optionally, the first mounting parts are spaced apart, and the positioning post is located between the two first mounting parts. When the sterilization module is installed into the first mounting part, the positioning through hole of the sterilization module is inserted into the positioning post, and the connection through hole of the sterilization module corresponds to the connection hole. In this way, the screw can pass through the connection through hole and be threadedly connected to the copper nut in the connection hole.

[0142] Optionally, such as Figure 18 As shown, the first tube sheet 40 also includes a snap-fit ​​plate 431. The snap-fit ​​plate 431 is located on the side of the first end plate 44 away from the heat exchange chamber. Two snap-fit ​​plates 431 arranged opposite each other define a snap-fit ​​groove 432. The detection module 47 is adapted to be installed in the snap-fit ​​groove 432, and the detection probe 471 of the detection module 47 extends through the snap-fit ​​groove 432 to the air outlet. The second mounting part 43 includes the snap-fit ​​groove 432.

[0143] In this embodiment, a simple and stable installation method is provided for the detection module 47 by setting a snap-fit ​​groove 432 formed by two snap-fit ​​plates 431 on the outer side of the first end plate 44 as a second mounting part 43. Furthermore, the detection probe 471 of the detection module 47 can directly extend through the snap-fit ​​groove 432 to the air vent area, allowing the probe to contact the core airflow without obstruction, thereby obtaining the most direct and accurate environmental parameter (such as temperature and humidity) measurement data, significantly improving detection accuracy.

[0144] Optionally, the detection device 30 includes a detection probe 471 and a connecting wire harness 472. Multiple second mounting portions 43 are provided, each including a first sub-mounting portion 433 and a second sub-mounting portion 434. The first sub-mounting portion 433 is used to mount the detection probe 471. The second sub-mounting portions 434 and the first sub-mounting portions 433 are sequentially spaced along the extending direction of the first end plate 44. The second sub-mounting portions 434 are used to mount the connecting wire harness 472. The number of second sub-mounting portions 434 can be one or more. When there are multiple second sub-mounting portions 434, they are sequentially spaced along the extending direction of the end plate. The first sub-mounting portion 433 being used to mount the detection probe 471 means that the first sub-mounting portion 433 can fix part of the detection probe, or fix the detection probe towards the end of the connecting wire harness. Any method of fixing the detection probe is an optional embodiment of this application. It can be understood that the first sub-mounting portion can also fix the end of the connecting wire harness towards the detection probe.

[0145] In this embodiment, the detection probe 471 of the detection device 30 and the connecting wire harness 472 are installed separately and arranged at intervals along the direction of the first end plate 44, achieving reasonable planning and organization of the installation space. The wire harness can be laid out in a serpentine pattern along the extension direction of the end plate to avoid swaying. This effectively avoids possible interference or entanglement of the connecting wire harness 472 with the detection probe 471, ensuring the reliability of signal transmission. Designing multiple wire harness mounting parts 41 and arranging them at intervals provides a flexible cable management solution that can adapt to detection modules 47 of different sizes and cable quantities, making the wiring neater, more standardized, and easier to maintain.

[0146] Optionally, the first tube sheet 40 further includes a baffle 46, which is disposed on the side of the side plate facing the evaporator 10. The baffle 46 is configured with a recess 435, and the second sub-mounting part 434 includes the recess 435; and / or, the first tube sheet 40 further includes a snap-fit ​​arm 436, one end of which is connected to the end plate and extends along the extension direction of the first end plate 44. The snap-fit ​​arm 436 and the end plate enclose a snap-fit ​​space 437, and the second sub-mounting part 434 includes the snap-fit ​​space 437.

[0147] In this embodiment, the recessed hole 435 on the baffle 46 and the snap-fit ​​space 437 formed by the snap-fit ​​arm 436 together constitute the second sub-mounting part 434. The recessed hole 435 provides a sinking space for the connecting wire harness, avoiding interference with the evaporator 10 fins. The recessed hole 435 helps to fix and organize the connecting wire harness, preventing it from becoming loose or damaged by exposure to airflow, thus improving aesthetics and safety.

[0148] The snap-fit ​​space 437 enclosed by the snap-fit ​​arm 436 and the end plate provides secondary positioning for the connecting wire harness. This double fixation ensures that the connecting wire harness remains taut during transportation and operation, preventing signal interruption or short circuits caused by loosening, and further improving the overall reliability of the machine.

[0149] Optionally, the mounting part 41 is located on the side of the first tube sheet 40 facing the air inlet 75 and / or the fresh air inlet.

[0150] In this embodiment, the mounting part 41 is set on the side of the first tube sheet 40 facing the air inlet 75, which ensures that all installed detection modules 47 and sterilization modules 48 can play their roles as soon as the airflow enters the evaporator 10, so that the detection modules 47 and sterilization modules 48 directly face the fresh air or air inlet, making the detection data more accurate and the sterilization more thorough, and making the most of the airflow path for efficient detection and sterilization.

[0151] Optionally, the first tube sheet 40 is located at the second end 19 of the evaporator 10, that is, the first tube sheet 40 is located at the end of the evaporator 10 away from the connecting tube assembly 20 along its length. This can prevent the detection module 47 and / or the sterilization module 48 from being affected by the high temperature and high humidity environment around the connecting tube assembly 20, ensuring the sterilization effect and the accuracy of the detection.

[0152] Optionally, the evaporator 10 includes a first heat exchange section 15 and a second heat exchange section 16 arranged in a bent manner, and the first tube sheet 40 includes a first tube sheet section 511 and a second tube sheet section 512. The first tube sheet section 511 is adapted to be disposed at one end of the first heat exchange section 15; the second tube sheet section 512 is adapted to be disposed at one end of the second heat exchange section 16, and the first tube sheet section 511 and the second tube sheet section 512 are connected to each other; wherein, the mounting part is disposed at the first tube sheet section 511.

[0153] Optionally, there is an upward-opening angle between the first tube sheet segment 511 and the second tube sheet segment 512. The first tube sheet 40 also includes a reinforcing connecting plate connected between the first tube sheet segment 511 and the second tube sheet segment 512. This can improve the strength of the first tube sheet and prevent deformation of the first tube sheet.

[0154] The detection module 47 and sterilization module 48 are installed on the first tube sheet 40. The detection module 47 has good detection performance for various detection indicators and meets the testing standards. Various models of sterilization modules 48 can also be integrated, with sterilization and detection integrated into the second tube sheet 50, and fixed by the first mounting part 42 and the second mounting part 43 respectively. This makes the sensor module and sterilization module 48 of the air conditioner, especially the embedded air conditioner, easy to install, securely fixed, easy to maintain, and accurate in detection. This also increases the number of detection modules 47 and sterilization modules 48 that can be installed in the embedded air conditioner, and the arrangement is more centralized, facilitating maintenance.

[0155] like Figures 19 to 21 As shown, this embodiment of the present disclosure also provides a tube sheet for an evaporator (hereinafter referred to as the second tube sheet 50 for ease of description). The second tube sheet 50 includes a tube sheet body 51 and a support leg 52. The tube sheet body 51 is adapted to be disposed at the end of the evaporator 10 in the length direction. The support leg 52 is disposed on the tube sheet body 51. The support leg 52 is adapted to protrude toward the end of the tube sheet body 51 away from the evaporator 10. When the evaporator 10 is placed vertically, the support leg 52 supports the second tube sheet 50 and the evaporator 10 below.

[0156] In this embodiment, the second tube sheet 50 of the evaporator 10 is provided with a support foot 52. When the length direction of the evaporator 10 is placed vertically, the support foot 52 supports the second tube sheet 50 and the evaporator 10 below. In this way, the support foot 52 can stably support the evaporator 10. During welding, the evaporator 10 can be operated vertically without bending over. The operator can operate while standing, which improves the convenience of assembling and operating the evaporator 10.

[0157] Optionally, one end of the support leg 52 is connected to the end of the tube sheet body 51 away from the evaporator 10, and the support leg 52 extends in a direction away from the tube sheet body 51; wherein, there are multiple support legs 52, and when the evaporator is placed vertically, the other ends of the multiple support legs 52 are at the same height.

[0158] In this embodiment, multiple legs 52 of equal height form an equal-surface support, which makes the second tube sheet 50 bear force evenly and prevents the evaporator 10 from shaking when placed vertically; the extended leg 52 structure also increases the distance between the second tube sheet 50 and the ground, making room for the operation of the lower tools, welding gun or detection probe 471, and further improving the convenience of on-site operation.

[0159] Optionally, such as Figure 20As shown, the evaporator 10 includes a first heat exchange section 15 and a second heat exchange section 16 arranged in a bent manner. The second tube sheet 50 includes a first tube sheet section 511 and a second tube sheet section 512. The first tube sheet section 511 is adapted to be disposed at one end of the first heat exchange section 15. The second tube sheet section 512 is adapted to be disposed at one end of the second heat exchange section 16. The first tube sheet section 511 and the second tube sheet section 512 are connected to each other. Both the first tube sheet section 511 and the second tube sheet section 512 are provided with support feet 52.

[0160] In this embodiment, the first tube sheet segment 511 and the second tube sheet segment 512 are each equipped with a support leg 52, forming two separate but equally high lower support points. This provides free expansion space for the bending section and ensures the overall center of gravity is stable when the whole machine is placed vertically, preventing the equipment from tipping over due to the overturning moment generated by the bending angle, thus improving the overall support stability of the support leg 52 for the evaporator 10.

[0161] Optionally, there is an upward-opening angle between the first tube sheet segment 511 and the second tube sheet segment 512. The first tube sheet 40 also includes a reinforcing connecting plate connected between the first tube sheet segment 511 and the second tube sheet segment 512. This can improve the strength of the second tube sheet and prevent deformation of the second tube sheet.

[0162] Optionally, the lower end of the second tube sheet 50 is provided with a wiring storage structure 53, which is used to store wire harnesses (hereinafter referred to as the second wire harnesses for easy distinction).

[0163] In this embodiment, a wiring storage structure 53 is directly built into the bottom of the tube sheet, allowing sensor wires, power cables, etc., to be concealed along the lower edge of the tube sheet. This prevents the second wiring harness from dragging on the ground or being burned by high-temperature welds, improving the cleanliness and safety of the equipment. It also reduces the need for additional cable trays, lowering costs. Furthermore, the wiring storage structure 53 on the tube sheet prevents the fins of the evaporator 10 from cutting the second wiring harness, preventing water leakage and protecting the second wiring harness.

[0164] When the second tube sheet 50 is applied in an embedded air conditioner, due to the special nature of embedded air conditioners, a drip tray structure is required to collect the condensate from the evaporator 10. The drip tray needs to cover all areas where water is dripping. In the past, the second wire harness that was thrown from the louvers and coil sensors could not be effectively stored because of its long travel. If there was water on it, the drip tray would easily not be able to catch it and it would drip out. If it could not be stored accurately and was too close to the fins of the evaporator 10, it would also cut the second wire harness. In this embodiment, a wiring storage structure 53 is designed on the second tube sheet 50 of the evaporator 10, which effectively stores the second wire harness and also provides good protection for the second wire harness. It can also prevent condensate from dripping onto the second wire harness and causing the risk of water leakage.

[0165] Optionally, the cable storage structure 53 includes a retaining plate 532, which is located at the lower end of the second tube sheet 50. The retaining plate 532 and the tube sheet body 51 enclose a first cable routing groove 531, which is used to store the second cable bundle; and / or, the cable storage structure 53 includes a hook 534, which is located at the lower end of the second tube sheet 50. The lower end of the hook 534 is provided with a second cable routing groove 533, which is used to store the second cable bundle.

[0166] In this embodiment, the first wiring channel 531 enables the second wire harness to be quickly inserted and fixed; the second wiring channel 533 provides a hanging storage solution, the clamping plate 532 can fix the second wire harness and prevent the second wire harness from moving, and the hook 534 is suitable for hanging the second wire harness. In this way, when storing the second wire harness, the degree of fixation of the second wire harness can be guaranteed, and the flexibility of hanging the second wire harness can be improved.

[0167] Optionally, the first tube sheet segment 511 is provided with a first support leg 521, and the second tube sheet segment 512 is provided with a second support leg 522. The first support leg 521 and the second support leg 522 are adjacent to each other and spaced apart; wherein, the cable storage structure 53 is located between the first support leg 521 and the second support leg 522.

[0168] In this embodiment, the cable management structure 53 is arranged in the "gap" between the first leg 521 and the second leg 522, using the natural spacing between the two legs 52 to form a protective barrier, thus hiding the cable harness and protecting it from external impacts. This also prevents the cable management structure 53 from occupying additional space in other components, and the legs 52 also provide physical isolation to protect the cable harness from compression. Furthermore, since the first leg 521 is located at the first tube sheet segment 511 and the second leg 522 is located at the second tube sheet segment 512, the cable management structure 53 is located at the connection between the first tube sheet segment 511 and the second tube sheet segment 512. Because the connection between the first heat exchange section 15 and the second heat exchange section 16 is bent, the connection between the first tube sheet segment 511 and the second tube sheet segment 512 also corresponds to the connection between the first heat exchange section 15 and the second heat exchange section 16, and there is also a bend there. In other words, the wiring storage structure 53 is closer to the connection between the first heat exchange section 15 and the second heat exchange section 16, which can shorten the wiring length and improve the convenience of wiring harness organization.

[0169] Optionally, such as Figure 20As shown, there are multiple clamping plates 532, including a first clamping plate and a second clamping plate. The first clamping plate is located on the first tube plate section 511, and the second clamping plate is located on the second tube plate section 512. The hook 534 is located between the two first clamping plates, so that the two clamping plates 532 form two first wiring channels 531. The wire harness is fixed through the two first wiring channels 531 at both ends, and then hooked into the second wiring channel 533 between the two first wiring channels 531. Since the second wiring channel 533 is located above the hook 534, the wire harness can be more flexibly placed in the second wiring channel 533. The second wiring channel 533 plays a role in stopping and limiting, preventing the wire harness from moving. Through the cooperation of the first wiring channel 531 and the second wiring channel 533, not only can the wire harness be restrained, but the convenience of wire harness storage is also improved, and the wire harness is prevented from being too tightly wound and difficult to disassemble.

[0170] Optionally, there may be multiple hooks 534, which form multiple second wiring channels 533, and the multiple hooks 534 are located between two first wiring channels 531.

[0171] Optionally, such as Figure 20 As shown, along the circumference of the second tube sheet 50, the length of the first tube sheet segment 511 is greater than the length of the second tube sheet segment 512, and the number of first supports 521 is greater than the number of second supports 522. Here, the second tube sheet 50 is matched with the evaporator 10. Along the circumference of the evaporator 10, the length of the first heat exchange section 15 is greater than the length of the second heat exchange section 16. Therefore, the length of the first tube sheet segment 511 is greater than the length of the second tube sheet segment 512. The number of first supports 521 provided in the first tube sheet segment 511 is greater than the number of second supports 522 provided in the second tube sheet segment 512. This can improve the support points of the first tube sheet segment 511, thereby improving the stability of the evaporator 10 when it is placed vertically.

[0172] Optionally, the tube sheet body 51 is provided with a fixing ear 54 at the end away from the evaporator 10. The fixing ear 54 is adapted to be connected to an external component and extends in a direction away from the tube sheet body 51. When the evaporator is placed vertically, the height of the end of the support 52 away from the tube sheet body 51 is the same as the height of the end of the fixing ear 54 away from the tube sheet body 51.

[0173] In this embodiment, the fixing lug 54 is at the same height as the support leg 52, so that the evaporator 10 can stand upright on the ground by means of the support leg 52 when placed vertically. This ensures that the fixing lug 54 does not interfere with the support leg 52 when the evaporator 10 is placed, facilitating horizontal calibration. At the same time, the fixing lug 54 can also play a certain supporting role, improving the stability of the evaporator 10 when placed vertically.

[0174] Optionally, the fixing ear 54 is provided on the second tube sheet section 512. Optionally, the fixing ear 54 is provided at the end of the second tube sheet section 512 away from the first tube sheet section 511.

[0175] In some alternative embodiments, the fixing lug 54 and the second support leg 522 are spaced apart on the second tube sheet section 512, and the two first support legs 521 are spaced apart on the first tube sheet section 511. In this way, the two first support legs 521, one second support leg 522 and the fixing lug 54 form a multi-point support, which improves the uniformity of force on the support leg 52 and the fixing lug 54 under the tube sheet when the evaporator 10 is placed vertically, and can stably support the evaporator 10.

[0176] Optionally, the fixing lug 54 is located on the first tube sheet section 511, which can further increase the support points and improve the support stability.

[0177] Optionally, such as Figure 21 As shown, the support leg 52 includes a first wall surface and a second wall surface spaced apart along the width direction of the support leg 52, wherein at least one of the first wall surface and the second wall surface is an inclined surface 523.

[0178] In this embodiment, the support leg 52 is provided with an inclined surface 523, so that when the evaporator 10 is placed vertically, the water on the surface of the evaporator 10 can also flow down along the inclined surface 523 of the support leg 52, thus preventing water from accumulating in the evaporator 10.

[0179] Optionally, the inclined surface 523 is inclined toward the first wall or the second wall in a direction away from the tube sheet body 51. This can ensure drainage effect, reduce material usage, and reduce the weight and cost of the evaporator 10.

[0180] Optionally, the second tube sheet 50 is located at the second end 19 of the evaporator 10, that is, the second tube sheet 50 is located at the end of the evaporator 10 away from the connecting tube assembly 20, and the first end 18 of the evaporator 10 faces upward, which facilitates the assembly operation of the connecting tube assembly 20 and the evaporator 10.

[0181] In this embodiment, the support legs 52 of the second tube sheet 50 allow the evaporator 10 to stand upright and be stable, enabling welders to stand up and weld, thus improving operational convenience. Furthermore, by providing a wiring storage structure 53 on the second tube sheet 50, the second wiring harness of devices such as coil sensors of the evaporator 10 can be precisely and effectively stored, preventing the evaporator 10 fins from cutting the second wiring harness and also preventing water leakage, thus protecting the second wiring harness.

[0182] Optionally, the second wiring harness is electrically connected to the evaporator coil and / or the sensor.

[0183] In some alternative embodiments, the first tube sheet and the second tube sheet are the same tube sheet.

[0184] This disclosure provides a fourth tube sheet, which includes both the technical features of the aforementioned first tube sheet 40 and the technical features of the aforementioned second tube sheet 50.

[0185] Optionally, such as Figure 20 As shown, the fourth tube sheet has a support leg 52 and a mounting part 41. The support leg 52 is located on the first end plate 44, and the support extends from the first end plate 44 in a direction away from the evaporator 10. The mounting part 41 is located on the first end plate 44. In this way, the fourth tube sheet not only provides support, but also allows for the installation of the detection module 47 or the sterilization module 48, realizing the multi-functional integration of the fourth tube sheet.

[0186] Optionally, the mounting part 41 is provided on the first end plate 44 corresponding to the first tube sheet section 511.

[0187] Optionally, the fourth tube sheet includes a first tube sheet section 511 and a second tube sheet section 512. The first tube sheet section 511 is adapted to be disposed at one end of the first heat exchange section 15; the second tube sheet section 512 is adapted to be disposed at one end of the second heat exchange section 16, and the first tube sheet section 511 and the second tube sheet section 512 are connected to each other. Both the first tube sheet section 511 and the second tube sheet section 512 are provided with support feet 52, and the first tube sheet section is provided with a mounting part.

[0188] Optionally, there is an upward-opening angle between the first tube sheet segment 511 and the second tube sheet segment 512. The first tube sheet 40 also includes a reinforcing connecting plate connected between the first tube sheet segment 511 and the second tube sheet segment 512. This can improve the strength of the fourth tube sheet and prevent the fourth tube sheet from deforming.

[0189] Optionally, the first mounting part 42 is located between the two first legs 521 of the first tube sheet section 511.

[0190] Optionally, the first tube sheet segment 511 is provided with a first wiring groove 531, a first mounting part 42, and a second sub-mounting part 434. When the second sub-mounting part 434 includes a snap-fit ​​space 437, the first wiring groove 531 and the snap-fit ​​space 437 (for ease of description, they are collectively referred to as the first wiring groove 531) are the same component. In this way, the first wiring groove 531 can accommodate both the second wire harness and the connection wire harness 472 of the detection device 30. This further improves the functional integration of the fourth tube sheet and facilitates maintenance and operation.

[0191] Optionally, such as Figures 22 to 24As shown, this embodiment of the present disclosure also provides a tube sheet for an evaporator (hereinafter referred to as the third tube sheet 60 for easy distinction). The third tube sheet 60 is provided with a positioning hole 63 and a connecting part 64. When the refrigerant pipe 14 is inserted into the evaporator 10 through the positioning hole 63, the third tube sheet 60 is limited to the connection with the evaporator 10, and the connecting part 64 of the third tube sheet 60 is adapted to correspond to the connecting mating part of the evaporator 10.

[0192] In this embodiment, the third tube sheet 60 is provided with a positioning hole 63. After the refrigerant pipe 14 passes through the positioning hole 63 and is inserted into the evaporator 10, a limiting position is formed between the third tube sheet 60 and the refrigerant pipe 14. This not only prevents the third tube sheet 60 from moving relative to the evaporator 10, but also positions the connection between the third tube sheet 60 and the evaporator 10. The connecting part 64 of the third tube sheet 60 corresponds to the connecting mating part of the evaporator 10. In this way, the operator can directly operate the connecting part 64 and the connecting mating part to realize the connection between the third tube sheet 60 and the evaporator 10. Due to the limiting and fixing effect of the positioning hole 63 and the refrigerant pipe 14, the third tube sheet 60 will not shift during the connection process. Even if the operator stands upright with one hand, they can make an accurate connection, avoiding the displacement of the connecting part 64 and the connecting mating part, ensuring the accuracy of the connection, and improving the convenience of the connection.

[0193] Optionally, the connecting pipe assembly 20 includes a refrigerant pipe 14, which is a gas pipe of the connecting pipe assembly 20. Optionally, the refrigerant pipe 14 is a gas manifold 21 or a gas pipe 22 connecting the connecting pipe assembly.

[0194] Optionally, the positioning hole 63 corresponds to the second air port 12, so that the refrigerant pipe 14 is a connecting pipe 22. The connecting pipe 22 passes through the positioning hole 63 and is inserted into the second air port, which can realize the positioning and limiting of the third tube sheet 60 and the evaporator 10.

[0195] Optionally, the refrigerant pipe 14 can be a pipe in the aforementioned connecting pipe group 20, or it can be a pipe of other forms.

[0196] Optionally, the evaporator 10 includes a first heat exchange section 15 and a second heat exchange section 16 arranged in a bent manner, and the third tube sheet 60 includes a first tube sheet connecting plate 61 and a second tube sheet connecting plate 62. The first tube sheet connecting plate 61 is adapted to be disposed at one end of the first heat exchange section 15; the second tube sheet connecting plate 62 is adapted to be disposed at one end of the second heat exchange section 16, and the second tube sheet connecting plate 62 is connected to the first tube sheet connecting plate 61; wherein, the first tube sheet connecting plate 61 is provided with a positioning hole 63.

[0197] In this embodiment, the evaporator 10 is a multi-stage heat exchanger. The first tube sheet connecting plate 61 and the second tube sheet connecting plate 62 of the third tube sheet 60 correspond to the first heat exchange section 15 and the second heat exchange section 16, respectively, thus ensuring the tube sheet configuration requirements of the multi-stage evaporator 10. Here, the first tube sheet connecting plate 61 is provided with a positioning hole 63, which allows the first tube sheet connecting plate 61 to achieve initial connection with the evaporator 10 under the action of the positioning hole 63 and the refrigerant pipe 14, and also limits the entire third tube sheet 60. This ensures that the connecting part 64 of the third tube sheet 60 can be precisely aligned with the connecting mating part of the evaporator 10, facilitating connection operations by the operator. Moreover, by providing the positioning hole 63 only in the first tube sheet connecting plate 61 for limiting, the third tube sheet 60 is not "fixed"ly connected to the evaporator 10, allowing for fine-tuning of the third tube sheet 60 and ensuring the reliability of the connection operation.

[0198] Optionally, such as Figure 23 As shown, the upper end of the third tube sheet 60 is provided with a rib 68, which can improve the structural strength of the upper end of the third tube sheet 60 and prevent the third tube sheet 60 from deforming.

[0199] Optionally, the rib 68 is formed by the third tube plate 60 protruding or recessing along the thickness direction.

[0200] Optionally, the reinforcing rib 68 is located on one side of the positioning hole 63.

[0201] Optionally, there are multiple positioning holes 63, and all of the multiple positioning holes 63 are provided on the first tube sheet connecting plate 61.

[0202] In this embodiment, multiple positioning holes 63 are centrally located on the first tube sheet connecting plate 61, thereby maximizing the number of positioning points within a limited space and significantly enhancing the overall anti-deflection capability when the refrigerant pipes 14 are inserted. This is especially suitable for multi-pipe systems, preventing the tilting of the third tube sheet 60 caused by single-point positioning failure, and limiting the positioning from multiple points, thereby improving the limiting effect of the positioning holes 63 and the refrigerant pipes 14.

[0203] Optionally, the positioning hole 63 includes a fully enclosed through hole, that is, the positioning hole is provided with a limiting edge in the circumference. In this way, after the refrigerant pipe 14 is inserted into the positioning hole 63, the positioning hole 63 is limited in the circumference with the refrigerant pipe 14, which can prevent the third tube sheet 60 from shifting.

[0204] Optionally, the first tube sheet connecting plate 61 and / or the second tube sheet connecting plate 62 are provided with a connecting portion 64.

[0205] In this embodiment, the connecting part 64 can be flexibly configured on the first tube sheet connecting plate 61, the second tube sheet connecting plate 62, or both. This degree of freedom allows the selection of the optimal connection point according to actual assembly requirements, enabling both unilateral quick locking and bilateral coordinated reinforcement to adapt to structural strength requirements under different working conditions.

[0206] Optionally, the connecting part 64 includes a screw hole.

[0207] In this embodiment, a screw hole is used as the connecting part 64, utilizing the mechanical advantages of threaded fastening to achieve a detachable, high-strength connection. The screw hole has low processing cost and is compatible with standard fasteners, significantly reducing assembly complexity and maintenance costs. In practical applications, the refrigerant pipe 14 passes through the positioning hole 63 and extends into the evaporator 10. The positioning hole 63 and the refrigerant pipe 14 serve as a fixed positioning structure, and the screw hole corresponds to the screw hole of the evaporator 10. This allows for single-handed screw tightening without interfering with the screw holes, improving assembly convenience.

[0208] Optionally, the tube sheet connection plate 60 is constructed with a plurality of grooves 65 with one side open, and when the refrigerant pipe 14 is adapted to be inserted into the heat exchanger 10 through the positioning hole 63, the coil of the heat exchanger 10 is adapted to be located in the groove 65.

[0209] In this embodiment, the groove 65 forms a semi-enclosed tube groove, and the coil of the heat exchanger 10 is inserted and embedded inside the groove 65. The groove 65 restricts the radial displacement of the coil of the heat exchanger 10 by physically containing it, and at the same time disperses the contact stress between the tube sheet connecting plate 60 and the coil of the heat exchanger 10, effectively suppressing fretting wear caused by vibration and extending the service life of the pipeline.

[0210] Optionally, the coil of heat exchanger 10 can be the heat exchanger's own heat exchange tubes, or it can be other pipes in the connected pipe group, which can be understood as other pipes besides the aforementioned refrigerant pipes.

[0211] Optionally, a connecting portion 64 is provided between some or all of the adjacent grooves 65.

[0212] In this embodiment, a connecting portion 64 is provided at the gap between adjacent grooves 65, so that the fastening force is directly applied to the dense area of ​​refrigerant pipes 14. This arrangement couples the connection point with the high-load area, significantly improving the local deformation resistance of the third tube sheet 60 and avoiding the risk of deformation caused by the grooves 65 weakening the structural strength.

[0213] Optionally, the connection between the first tube sheet connecting plate 61 and the second tube sheet connecting plate 62 is bent, which makes the movement and connection of the first tube sheet connecting plate 61 and the second tube sheet connecting plate 62 more flexible, and can also reduce the amount of material used and reduce costs.

[0214] Optionally, the third tube sheet 60 includes a body and a fixing plate 66. The body is provided with a positioning hole 63 and a connecting part 64. The fixing plate 66 is located at the circumferential end of the body and is adapted to be connected to an external component. The connection between the fixing plate 66 and the body forms a bend. The fixing plate 66 and / or the connection between the fixing plate 66 and the body is provided with a reinforcing rib 67.

[0215] In this embodiment, the fixing plate 66 is bent at the connection with the body, so that the fixing plate 66 can better fit and connect with external components such as the shell 70, thereby improving the sealing effect of the evaporator 10.

[0216] Optionally, the external component is a housing 70, and the fixing plate 66 is connected to the housing 70, which can improve the installation stability of the evaporator 10.

[0217] Optionally, the fixing plate 66 is attached to and connected to the top wall 78 of the housing 70, which increases the contact area between the fixing plate 66 and the top wall 78 of the housing 70 and improves the sealing performance of the evaporator 10.

[0218] Furthermore, the connection between the fixing plate 66 and the main body forms a bend. This bend can cause the fixing plate 66 to wrinkle or crack under die stamping. While disconnecting the fixing plate 66 from the main body could mitigate this risk, the strength of the fixing plate 66 would be insufficient. This embodiment incorporates reinforcing ribs 67 at the fixing plate 66 and the connection between the fixing plate 66 and the main body, ensuring strength without cutting and preventing wrinkling or cracking. This not only improves the sealing performance of the evaporator 10 but also optimizes the die-making process, avoiding defects such as wrinkling and cracking. Optionally, fixing plates 66 are provided at both ends of the third tube sheet 60 along its circumference, ensuring connection stability at both ends of the third tube sheet 60 and guaranteeing the sealing effect of the evaporator 10.

[0219] In some alternative embodiments, the first tube sheet and the third tube sheet are the same tube sheet, or the second tube sheet and the third tube sheet are the same tube sheet, or the first tube sheet, the second tube sheet and the third tube sheet are the same tube sheet. Optionally, when the third tube sheet is used in conjunction with the online tube bundle, the first tube sheet and / or the second tube sheet can both be tube sheets used in conjunction with the online tube bundle.

[0220] Optionally, embodiments of this disclosure also provide a tube sheet, which includes parts or technical features of any one, any two, any three, or all four of the aforementioned first, second, third, and fourth tube sheets. That is, some or all features of the first, second, third, and fourth tube sheets can be combined into a single tube sheet. For example, a tube sheet may include a mounting portion of the first tube sheet and related parts or all of its technical features, while the tube sheet may also include support legs and wiring storage structures for the second tube sheet, and the tube sheet may also include positioning holes and connecting portions for the third tube sheet and related parts or all of its technical features.

[0222] This disclosure also provides an air conditioner, which includes an evaporator as described in any of the above embodiments.

[0223] The air conditioner provided in this disclosure includes the evaporator of any of the above embodiments, and therefore has the beneficial effects of the evaporator of any of the above embodiments, which will not be repeated here. Optionally, the air conditioner can be a built-in air conditioner, etc.

[0224] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them.
