[0037] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0038] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of the particular examples in the following description are depicted by referring to drawings. Of course, they are merely examples and are intended to explain the present application, and are not intended to limit the present application. In addition, the present application can repeatedly refer to reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0039] In the related art, the high-voltage wire and the low-voltage wire are wired together from the wiring groove on the bottom plate, and the electromagnetic interference problem exists when the high-voltage wire and the low-voltage wire are wired together. Moreover, the high-voltage wire and the low-voltage wire are wired together from the wiring groove on the bottom plate, which causes the problem of too many wires in the wiring groove, resulting in low assembly efficiency and low production qualification rate. In order to at least solve one of the above technical problems, the present application proposes a wiring method of an air conditioner 100.

[0040] Next, with reference to the drawings, the air conditioner 100 according to the embodiment of the present application is described.

[0041] As Figure 1 andFigure 2 As shown, the air conditioner 100 may include: a chassis 1, a ventilation and heat exchange component, an electrical control component 4, and a functional component 5. The ventilation and heat exchange component is located on the chassis 1 and includes a heat exchange assembly 2 and a ventilation assembly 3.

[0042] It should be noted that the specific composition of chassis 1 is not limited. For example, chassis 1 can be a one-piece structure or a split structure. When chassis 1 is a one-piece structure, both heat exchange component 2 and ventilation component 3 are located on the one-piece chassis 1. When chassis 1 is a split structure, heat exchange component 2 and ventilation component 3 can be located on different parts of chassis 1. For example, chassis 1 includes an upper chassis 1 and a lower chassis 1, heat exchange component 2 can be located on the upper chassis 1, ventilation component 3 can be located on the lower chassis 1, and so on.

[0043] like Figure 1 and Figure 2 As shown, the chassis 1 has a first wiring structure 101, which is adapted to carry a first low-voltage line. For example, in some embodiments, the air conditioner 100 may include some low-voltage driving components, such as air guide components. The air guide components may include air guide elements and air guide motors that drive the air guide elements to move. The air guide elements may be air guide plates or air guide louvers. The air guide motors may be connected to the electronic control components 4 through the first low-voltage line. The first low-voltage line may be routed through the first wiring structure 101, and its two ends are respectively connected to the electronic control components 4 and the air guide motors.

[0044] like Figure 1 and Figure 2 As shown, the two sides of the length of the ventilation and heat exchange component are the first side and the second side, respectively. The electrical control component 4 is located on the first side of the ventilation and heat exchange component, and the functional component 5 is located on the second side of the ventilation and heat exchange component. That is, the electrical control component 4 and the functional component 5 are respectively located on the two sides of the length of the ventilation and heat exchange component. For example Figure 1 As shown, the length direction of the ventilation and heat exchange component is left and right, the electrical control component 4 is located on the left side of the ventilation and heat exchange component, and the functional component 5 is located on the right side of the ventilation and heat exchange component.

[0045] like Figure 1 and Figure 2 As shown, functional component 5 is a high-voltage drive component. The ventilation and heat exchange component has a second wiring structure 102. Functional component 5 is connected to the electrical control component 4 via a first high-voltage line 6 that runs through the second wiring structure 102. That is, the first high-voltage line 6 runs through the second wiring structure 102 and its two ends are respectively connected to the electrical control component 4 and the functional component 5. The first wiring structure 101 on the chassis 1 and the second wiring structure 102 on the ventilation and heat exchange component are spaced apart to separate the first high-voltage line 6 from the first low-voltage line.

[0046] Therefore, according to the embodiment of the present invention, the air conditioner 100, by providing a second wiring structure 102 for the first high-voltage line 6 on the ventilation and heat exchange component, separates the first high-voltage line 6 from the first low-voltage line running on the chassis 1, thereby avoiding electromagnetic interference, signal interference, and other problems caused by the first high-voltage line 6 and the first low-voltage line running together, thus improving the reliability of the air conditioner 100. Furthermore, separating the first high-voltage line 6 and the first low-voltage line improves wiring space, increases production efficiency, and increases the yield rate.

[0047] It should be noted that the specific type of functional component 5 is not limited; for example, it can be a fresh air component, or a high-voltage sterilization and disinfection component, etc. Furthermore, it should be noted that the electrical control component 4 can be an electrical control box, which contains circuit boards, wiring boards, etc., including power supply circuits, control circuits, etc.

[0048] Furthermore, it should be noted that, in addition to the first high-voltage line 6 that connects the functional component 5 and the electronic control component 4 as described above, the air conditioner 100 according to the present invention may also have other high-voltage lines, such as a second high-voltage line for connecting the ventilation component 3 and the electronic control component 4. The second high-voltage line does not need to be routed through the second wiring structure 102, but if necessary, the second high-voltage line may be routed through the second wiring structure 102.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the heat exchange assembly 2 may include an electric auxiliary heater 21, which extends along the length of the ventilation heat exchange component. The second wiring structure 102 includes wire clips 211 at both ends of the electric auxiliary heater 21. The first high-voltage line 6 is located outside the electric auxiliary heater 21, and both ends of the first high-voltage line 6 are respectively limited by the wire clips 211 on the corresponding sides. For example, in Figure 1 In the example shown, the length of the ventilation and heat exchange component extends in the left-right direction, the electric auxiliary heater 21 extends in the left-right direction, the second wiring structure 102 includes a wire buckle 211 at the left end of the electric auxiliary heater 21 and a wire buckle 211 at the right end of the electric auxiliary heater 21, the first high-voltage line 6 is located outside the electric auxiliary heater 21, the left end of the first high-voltage line 6 is limited by the wire buckle 211 at the left end of the electric auxiliary heater 21, and the right end of the first high-voltage line 6 is limited by the wire buckle 211 at the right end of the electric auxiliary heater 21.

[0050] Therefore, the electric auxiliary heater 21 can be used to limit the first high-voltage line 6, allowing it to run along the length of the electric auxiliary heater 21. This makes it easy for both ends of the first high-voltage line 6 to extend to the functional component 5 and the electronic control component 4. This wiring method is simple and does not require the introduction of other components, simplifying the structure. Furthermore, since the first high-voltage line 6 can be routed via the electric auxiliary heater 21, it can be easily separated from the first low-voltage line routed via the first wiring structure 101 on the chassis 1, thereby effectively solving the electromagnetic interference problem between the first high-voltage line 6 and the first low-voltage line.

[0051] In some specific examples, the electric auxiliary heater 21 may include a heating body and two mounting bases. The heating body extends along the length of the ventilation and heat exchange component, and the two mounting bases are respectively located at both ends of the extension direction of the heating body. The wire clip 211 can be machined onto the mounting bases without affecting the structure of the heating body itself, thereby simplifying the production and manufacturing of the electric auxiliary heater 21.

[0052] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, each end of the first high-voltage line 6 is provided with a stopper 61. The two stoppers 61 stop on the outside of the corresponding wire buckle 211, that is, on the side away from the center of the length of the electric auxiliary heater 21. For example, the left end of the first high-voltage line 6 has a stopper 61, which stops on the left side of the wire buckle 211 on the left. The right end of the first high-voltage line 6 has a stopper 61, and the left end of the stopper 61 stops on the left side of the wire buckle 211 on the left. This can improve the limiting stability and reliability of the first high-voltage line 6 and reduce the movement of the first high-voltage line 6 along its own length. The structure of the stopper 61 is not limited. For example, the stopper 61 can be an annular retaining ring wrapped around the first high-voltage line 6, or a number of protruding ribs spaced apart along the circumference of the first high-voltage line 6, etc., which will not be elaborated here.

[0053] Of course, the present invention is not limited to this. The first high-voltage line 6 may not necessarily run outside the electric auxiliary heater 21. For example, in some other embodiments of the present invention, when the heat exchange component 2 includes the electric auxiliary heater 21 and the electric auxiliary heater 21 extends along the length extension direction of the ventilation heat exchange component, the second wiring structure 102 may also include a wiring cavity formed in the electric auxiliary heater 21. The first high-voltage line 6 runs through the wiring cavity, and both ends of the first high-voltage line 6 extend outside the two ends of the electric auxiliary heater 21. Thus, the problem of the first high-voltage line 6 being suspended outside the electric auxiliary heater 21 and the problem of the first high-voltage line 6 affecting the heat transfer of the electric auxiliary heater 21 to the outside can be avoided. Therefore, the electric auxiliary heater 21 can be used to protect the first high-voltage line 6, and the heat transfer efficiency of the electric auxiliary heater 21 can be guaranteed to a certain extent.

[0054] It is understood that "electric auxiliary heating 21" mentioned in this article refers to PTC, an abbreviation for Positive Temperature Coefficient, which generally refers to semiconductor materials or components with a large positive temperature coefficient.

[0055] Regardless of whether the first high-voltage line 6 runs from the outside or the inside of the electric auxiliary heater 21, in some optional embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the heat exchange assembly 2 may include two mounting plates 22 extending along the length of the ventilation heat exchange component. The two mounting plates 22 are respectively disposed on both sides of the electric auxiliary heater 21. The second wiring structure 102 includes wire-passing holes 221 disposed on the two mounting plates 22, and the two ends of the first high-voltage wire 6 pass through the corresponding wire-passing holes 221. This facilitates the connection of the two ends of the first high-voltage wire 6 to the functional component 5 and the electrical control component 4, and allows for better limiting of the two ends of the first high-voltage wire 6, improving the wiring stability and reliability of the first high-voltage wire 6. Furthermore, it shortens the wiring length of the first high-voltage wire 6, simplifies the wiring of the first high-voltage wire 6 when passing through the mounting plates 22, reduces costs, and further improves the wiring stability and reliability.

[0056] For example in Figure 1 and Figure 3 In the example shown, the heat exchange assembly 2 includes two mounting plates 22, namely a first mounting plate 22a on the left and a second mounting plate 22b on the right. The first mounting plate 22a and the second mounting plate 22b are respectively disposed on the left and right sides of the electric auxiliary heater 21. The second wiring structure 102 includes a wire through hole 221 on the first mounting plate 22a and a wire through hole 221 on the second mounting plate 22b. Figure 2 The left end of the first high-voltage line 6 passes through the wire hole 221 on the left side of the first mounting plate 22a, so that the left end of the first high-voltage line 6 does not need to go around the first mounting plate 22a, but only needs to pass through the first mounting plate 22a, and can be easily connected to the functional component 5 on the left side of the first mounting plate 22a. This shortens the wiring length of the left end of the first high-voltage line 6, and the wiring at the left end of the first high-voltage line 6 is more stable and reliable. Figure 5 The right end of the first high-voltage line 6 passes through the wire hole 221 on the second mounting plate 22b on the right side. Thus, the right end of the first high-voltage line 6 does not need to go around the second mounting plate 22b. It can be easily connected to the electrical control component 4 on the right side of the second mounting plate 22b by simply passing through the second mounting plate 22b. This shortens the wiring length of the right end of the first high-voltage line 6 and makes the wiring of the right end of the first high-voltage line 6 more stable and reliable.

[0057] In some embodiments of the present invention, such as Figure 3 and Figure 6As shown, at least one end of the electric auxiliary heater 21 is provided with a baffle 212. The baffle 212 blocks the wire hole 221 on the corresponding side and avoids the first high voltage line 6. That is, the area of ​​the wire hole 221 is larger than the cross-sectional area of ​​the first high voltage line 6. The baffle 212 blocks a part of the wire hole 221. The end of the first high voltage line 6 passes through the part of the wire hole 221 that is not blocked by the baffle 212, thereby realizing that the baffle 212 blocks the wire hole 221 on the corresponding side and avoids the first high voltage line 6.

[0058] Therefore, while ensuring that the first high-voltage line 6 is routed through the wire passage hole 221, air leakage at the wire passage hole 221 can be minimized, reducing the probability of condensation and other problems caused by air leakage. Furthermore, setting the area of ​​the wire passage hole 221 to be larger than the cross-sectional area of ​​the first high-voltage line 6 facilitates the threading of the first high-voltage line 6, reduces routing difficulty, and improves assembly efficiency. In addition, to further reduce air leakage at the wire passage hole 221, it can be further sealed with sponge or foam after threading to improve the reliability of air leakage prevention.

[0059] It should be noted that there are various structural forms of the baffle 212 and various ways of blocking the wire passage hole 221. For example, the baffle 212 can be a hollow design with a through hole 213. The wire passage hole 221 can completely cover and extend beyond the through hole 213. The first high-voltage wire 6 passes through the overlapping area of ​​the through hole 213 and the wire passage hole 221, thus ensuring that the baffle 212 avoids the first high-voltage wire 6. Furthermore, to facilitate the passage of the first high-voltage wire 6 through the through hole 213, the through hole 213 can also be designed to have an opening. As another example, the baffle 212 can be a solid design without a hollow design and without a through hole 213. The baffle 212 only blocks a part of the wire passage hole 221. The first high-voltage wire 6 passes through the side of the baffle 212 to pass through the part of the wire passage hole 221 that is not blocked by the baffle 212, thus achieving the avoidance of the first high-voltage wire 6 by the baffle 212.

[0060] For example in Figure 3 and Figure 6 In the specific example shown, the left end of the electric auxiliary heater 21 is provided with a baffle 212. The baffle 212 blocks the wire hole 221 on the first mounting plate 22a and avoids the left end of the first high voltage line 6. That is, the baffle 212 blocks a part of the wire hole 221 on the first mounting plate 22a. The left end of the first high voltage line 6 passes through the part of the first mounting plate 22a that is not blocked by the baffle 212, thereby realizing that the baffle 212 blocks the wire hole 221 on the left side and avoids the left end of the first high voltage line 6.

[0061] For example, in some specific examples, the right end of the electric auxiliary heater 21 is provided with a baffle 212. The baffle 212 blocks the wire hole 221 on the second mounting plate 22b and avoids the right end of the first high voltage line 6. That is, the baffle 212 blocks a part of the wire hole 221 on the second mounting plate 22b, and the right end of the first high voltage line 6 passes through the part of the second mounting plate 22b that is not blocked by the baffle 212, thereby realizing that the baffle 212 blocks the wire hole 221 on the right side and avoids the right end of the first high voltage line 6.

[0062] For example, in some specific examples, the left end of the electric auxiliary heater 21 is provided with a baffle 212, and the right end of the electric auxiliary heater 21 is also provided with a baffle 212. The baffle 212 on the left side of the electric auxiliary heater 21 blocks the wire hole 221 on the first mounting plate 22a and avoids the left end of the first high voltage line 6. That is, the baffle 212 on the left side blocks a portion of the wire hole 221 on the first mounting plate 22a, and the left end of the first high voltage line 6 passes through the part of the first mounting plate 22a that is not blocked by the baffle 212, thereby achieving the effect that the baffle 212 blocks the wire hole 221 on the left side and avoids the left end of the first high voltage line 6. The baffle 212 on the right side of the electric auxiliary heater 21 blocks the wire hole 221 on the second mounting plate 22b and avoids the right end of the first high voltage line 6. That is, the baffle 212 on the right side blocks a portion of the wire hole 221 on the second mounting plate 22b, and the right end of the first high voltage line 6 passes through the part of the second mounting plate 22b that is not blocked by the baffle 212, thereby achieving the effect that the baffle 212 blocks the wire hole 221 on the right side and avoids the right end of the first high voltage line 6.

[0063] Of course, the present invention is not limited to this; the first high-voltage line 6 may also not be routed through the electric auxiliary heater 21. For example, in some other embodiments of the present invention, such as... Figure 7 and Figure 8 As shown, the ventilation assembly 3 may include a volute 31 and a fan 32. The volute 31 forms the volute of the air duct where the fan 32 is located. The second wiring structure 102 includes a wiring groove 311 located on the volute 31 and outside the air duct. The length of the volute 31 extends along the length extension direction of the ventilation and heat exchange component. The first high-voltage line 6 is routed through the wiring groove 311. Thus, the first high-voltage line 6 can be routed using the volute 31, allowing it to run along the length extension direction of the volute 31. This makes it easy for both ends of the first high-voltage line 6 to extend to the functional component 5 and the electrical control component 4. This wiring method is simple and does not require the introduction of other components, simplifying the structure.

[0064] Furthermore, the first high-voltage line 6 can be routed via a volute, easily separating it from the first low-voltage line routed via the first wiring structure 101 on the chassis 1, thereby effectively solving the electromagnetic interference problem between the first high-voltage line 6 and the first low-voltage line. In addition, since the wiring trough 311 is located outside the air duct, the routing of the first high-voltage line 6 can avoid adversely affecting the ventilation effect of the air duct, thus ensuring the reliability and effectiveness of ventilation and reducing wind resistance.

[0065] It should be noted that the shape and position of the wiring groove 311 are not limited. For example, multiple support ribs can be provided on the volute 31 at intervals along the length direction of the volute 31. The support ribs are used to support the volute shape defined by the volute 31 and ensure that the volute 31 is lightweight and low in cost. The wiring groove 311 can be formed on each support rib to realize the wiring of the first high-voltage line 6. Of course, the present invention is not limited to this. When the volute 31 is a solid structure, the wiring groove 311 can be a volute 31 extending through the length of the volute 31, etc., which will not be elaborated here.

[0066] In addition, it should be noted that the structure of the impeller 32 is not limited. For example, it can be a cross-flow impeller 32 whose axis extends along the length of the ventilation and heat exchange component, or based on the design of the air duct, it can include multiple centrifugal impellers 32 whose axis extends along the length of the ventilation and heat exchange component and are arranged sequentially along the axial direction, etc. There are no restrictions here.

[0067] Furthermore, in some embodiments of the present invention, such as Figures 7-9 As shown, the second wiring structure 102 includes limiting grooves located on both sides of the length of the volute 31 on the chassis 1, with the two ends of the first high-voltage wire 6 respectively engaging with the corresponding limiting grooves. For example, the second wiring structure 102 may include a first limiting groove 13 and a second limiting groove 14 located on both sides of the length of the volute 31 on the chassis 1, with the two ends of the first high-voltage wire 6 respectively engaging with the first limiting groove 13 and the second limiting groove 14. Thus, the two ends of the first high-voltage wire 6 can be limited using the second limiting groove 14 on the chassis 1, thereby improving the wiring reliability and stability of the two ends of the first high-voltage wire 6. Furthermore, it eliminates the need to apply the entire wiring limiting task to the volute 31, thus simplifying the structural design and manufacturing of the volute 31.

[0068] In some alternative embodiments, such as Figure 7 and Figure 9As shown, the axial direction of the impeller 32 is the length extension direction of the ventilation and heat exchange component. The ventilation assembly 3 also includes a drive motor, which is located on the side of the impeller 32 near the electrical control component 4 along its axial direction. The drive motor includes a motor cover 33, and the second wiring structure 102 includes a first mating groove 331 on the motor cover 33. The first mating groove 331 engages with a corresponding limiting groove to limit the first high-voltage line 6. Therefore, the limiting of the corresponding end of the first high-voltage line 6 can be achieved simply and effectively, improving assembly efficiency and the reliability and stability of the wiring of the first high-voltage line 6.

[0069] For example, the length direction of the volute 31, the length extension direction of the ventilation and heat exchange component, and the axial direction of the impeller 32 are all left-right. The chassis 1 has a first limiting groove 13 located on the right side of the volute 31, and a second limiting groove 14 located on the left side of the volute 31. The right end of the first high-voltage line 6 is fitted into the first limiting groove 13 on the right side, and the left end of the first high-voltage line 6 is fitted into the second limiting groove 14 on the left side. An electrical control component 4 is provided on the right side of the ventilation and heat exchange component. The ventilation assembly 3 also includes a drive motor, which is located on the right side of the impeller 32. The drive motor includes a motor cover 33. The second wiring structure 102 includes a first mating groove 331 on the motor cover 33. The first mating groove 331 and the first limiting groove 13 on the right side fit together to limit the right end of the first high-voltage line 6.

[0070] Therefore, by cooperating with the motor cover 33 and the chassis 1, the right end of the first high-voltage wire 6 can be limited simply and effectively, improving assembly efficiency and the reliability and stability of the wiring of the first high-voltage wire 6. Optionally, both the first mating groove 331 and the first limiting groove 13 are open grooves, and the openings of the two open grooves are joined together to form a complete groove, limiting the first high-voltage wire 6. It should be noted that the shape of the open groove is not limited; for example, it can be a polygon, a semicircle, etc., and this is not restricted.

[0071] In some alternative embodiments, such as Figures 7-8 As shown, the heat exchange assembly 2 includes: a first mounting plate 22a, which is disposed on the side of the ventilation assembly 3 near the functional component 5 along its axial direction; and a second wiring structure 102, which includes a second mating groove 222 on the first mounting plate 22a, which engages with a corresponding limiting groove to limit the first high-voltage line 6. This allows for simple and effective limiting of the corresponding end of the first high-voltage line 6, improving assembly efficiency and the reliability and stability of the wiring of the first high-voltage line 6.

[0072] For example, the length direction of the volute 31, the length extension direction of the ventilation and heat exchange component, and the axial direction of the impeller 32 are all left-right. The chassis 1 has a first limiting groove 13 located on the right side of the volute 31, and a second limiting groove 14 located on the left side of the volute 31. The right end of the first high-voltage line 6 is fitted into the first limiting groove 13 on the right side, and the left end of the first high-voltage line 6 is fitted into the second limiting groove 14 on the left side. A functional component 5 is provided on the left side of the ventilation and heat exchange component, and a first mounting plate 22a is provided on the left side of the heat exchange assembly 2. The second wiring structure 102 includes a second mating groove 222 provided on the first mounting plate 22a. The second mating groove 222 and the second limiting groove 14 on the left side fit together to limit the left end of the first high-voltage line 6.

[0073] Therefore, by cooperating with the chassis 1, the left end of the first high-voltage line 6 can be easily and effectively limited, improving assembly efficiency and the reliability and stability of the wiring of the first high-voltage line 6. Optionally, the second mating groove 222 and the second limiting groove 14 are both open grooves, and the openings of the two open grooves are joined together to form a complete groove, limiting the first high-voltage line 6. It should be noted that the shape of the open groove is not limited, for example, it can be polygonal, semi-circular, etc., and there is no limitation here.

[0074] In some alternative embodiments, such as Figures 7-8 As shown, the two ends of the first high-voltage wire 6 are respectively interference-fitted into the corresponding limiting grooves. That is, the two ends of the first high-voltage wire 6 are respectively interference-fitted into the first limiting groove 13 and the second limiting groove 14. Thus, during assembly, the first limiting groove 13 and the second limiting groove 14 can be used to pre-position the first high-voltage wire 6, improving assembly efficiency. For example, during assembly, the first high-voltage wire 6 can be straightened along the wire routing groove 311 on the volute 31, and then the two ends of the first high-voltage wire 6 can be interference-fitted into the corresponding limiting grooves to achieve the pre-positioning effect. Then, the impeller 32, the drive motor, and the heat exchange assembly 2 can be installed, and the motor cover 33 of the drive motor and the first mounting plate 22a of the heat exchange assembly 2 can be used to press the two ends of the first high-voltage wire 6 together to achieve the limiting and positioning of the wire body.

[0075] Of course, the present invention is not limited thereto. In other embodiments of the present invention, the first high-voltage wire 6 may also be clearance-fitted with the corresponding limiting groove. Alternatively, the first high-voltage wire 6 and the first mating groove 331 may be clearance-fitted to improve assembly efficiency, or the first high-voltage wire 6 and the first mating groove 331 may be interference-fitted to improve the limiting reliability of the first high-voltage wire 6. The first high-voltage wire 6 and the second mating groove 222 may be clearance-fitted to improve assembly efficiency, or the first high-voltage wire 6 and the second mating groove 222 may be interference-fitted to improve the limiting reliability of the first high-voltage wire 6.

[0076] In some optional embodiments, each end of the first high-voltage line 6 is provided with a stopper 61, which stops on the outside of the corresponding limiting groove, i.e., on the side away from the volute tongue 31. For example, specifically, the left and right ends of the first high-voltage line 6 are each provided with a stopper 61. The stopper 61 at the left end stops on the left limiting groove, such as the left side of the second limiting groove 14, and the stopper 61 at the right end stops on the right limiting groove, such as the right side of the first limiting groove 13. This can improve the routing stability and reliability of the first high-voltage line 6 and reduce the slippage of the first high-voltage line 6 along its own length. The structural form of the stopper 61 is not limited. For example, the stopper 61 can be an annular retaining ring surrounding the first high-voltage line 6, or a plurality of protruding ribs spaced apart along the circumference of the first high-voltage line 6, etc., which will not be elaborated here.

[0077] In some embodiments, such as Figure 7 As shown, the first wiring structure 101 includes a wiring channel 15 extending along the length of the ventilation and heat exchange component. This allows for simple and efficient routing of the first low-voltage line, and after routing along the wiring channel 15, the first low-voltage line can easily reach the electronic control component 4 and connect to it.

[0078] Optionally, the first wiring structure 101 may further include a wire clamping member 16 disposed in the wiring channel 15, thereby improving the wiring stability and reliability of the first low-voltage line. For example, the wire clamping member 16 may be an elastic clip, etc., to facilitate the wiring of the first low-voltage line. In addition, there may be multiple wire clamping members 16, which are spaced apart along the extension direction of the wiring channel 15.

[0079] For example, in some specific examples, such as Figure 7 As shown, the chassis 1 may include a first baffle 11 and a second baffle 12, both extending along the length of the ventilation and heat exchange component. The first baffle 11 is spaced between the second baffle 12 and the volute 31. The first wiring structure 101 includes a wiring channel 15 formed between the first baffle 11 and the second baffle 12. This effectively ensures that the first high-voltage line 6 and the first low-voltage line are separated, reducing electromagnetic interference.

[0080] The following describes two specific embodiments according to the present invention.

[0081] Example 1

[0082] Air conditioner 100 is a wall-mounted unit. A ventilation and heat exchange component is mounted on the chassis 1, comprising a fan assembly and a heat exchange assembly 2. To the left of the ventilation and heat exchange component is a functional component 5, which is a fresh air component, including a fresh air fan, a fresh air handling module, etc. The fresh air component also includes a drive circuit board requiring high-voltage power. To the right of the ventilation and heat exchange component is an electrical control component 4, which is an electrical control box.

[0083] like Figures 1-6 As shown, the heat exchange assembly 2 includes an electric auxiliary heater 21 and a heat exchanger 23. The heat exchanger 23 is provided with mounting plates 22 on its left and right sides respectively. Each mounting plate 22 is provided with a wire hole 221. The left and right ends of the electric auxiliary heater 21 are fixed on the mounting plates 22 on the left and right sides respectively. The left and right ends of the electric auxiliary heater 21 are provided with wire buckles 211 respectively. The left end of the electric auxiliary heater 21 is provided with a baffle 212 covering part of the left wire hole 221. The left and right ends of the first high voltage line 6 are provided with baffles 61 respectively.

[0084] During assembly, the left end of the first high-voltage wire 6 is secured in the left-side wire buckle 211, and the left-side stopper 61 stops on the left side of the left-side wire buckle 211. Then, the left end of the first high-voltage wire 6 passes through the wire hole 221 on the left-side mounting plate 22 to the left, so as to connect the left end of the first high-voltage wire 6 with the functional component 5. The baffle 212 blocks the area of ​​the wire hole 221 that is not passed through by the first high-voltage wire 6 to improve the air leakage problem.

[0085] The right end of the first high-voltage line 6 is locked in the wire buckle 211 on the right side, and the stop member 61 on the right side stops the wire buckle 211 on the right side. Then, the first high-voltage line 6 and the wire of the electric auxiliary heater 21 are together passed through the wire hole 221 on the right side of the mounting plate 22 to the right, so as to realize the connection between the left end of the first high-voltage line 6 and the wire of the electric auxiliary heater 21 and the electrical control component 4. Since there are many wires passing through the wire hole 221, the air leakage problem can be improved to a certain extent.

The wind turbine 32 is a cross-flow wind turbine 32 with its axis extending in the left and right direction. The volute 31 extends in the left and right direction and forms the volute of the air duct where the wind turbine 32 is located. A cable tray 311 located outside the air duct is formed on the volute 31 for passing the first high-voltage line 6.

[0089] The chassis 1 is designed with a first limiting groove 13 and a second limiting groove 14 for fixing the first high voltage line 6.

Both the first limiting groove 13 and the second limiting groove 14 are semi-circular grooves with their openings facing upwards. The right end of the first high voltage line 6 is interference-fitted with the first limiting groove 13, and the left end of the first high voltage line 6 is interference-fitted with the second limiting groove 14.

[0090] The drive motor is located at the right end of the impeller 32, and the lower part of the motor cover 33 of the drive motor is provided with a first mating groove 331, which is a semi-circular opening facing downwards. When the drive motor is installed on the chassis 1, the first mating groove 331 and the first limiting groove 13 cooperate to clamp the right end of the first high voltage line 6.

[0091] The heat exchange assembly 2 includes a heat exchanger 23 and mounting plates 22 located at the left and right ends of the heat exchanger 23. The mounting plate 22 at the left end of the heat exchanger 23 is a first mounting plate 22a. The lower part of the first mounting plate 22a is provided with a second mating groove 222, which is a semi-circular opening facing downwards. When the heat exchange assembly 2 is installed on the chassis 1, the second mating groove 222 engages with the second limiting groove 14 to clamp the left end of the first high-voltage line 6.

[0092] During assembly, the first high-voltage wire 6 is routed along the wiring groove 311 of the volute tongue 31, and both ends are interference-fitted into the limiting grooves on both sides of the chassis 1. Then, the heat exchange component 2 and the motor cover 33 are assembled onto the chassis 1 so that the first high-voltage wire 6 is pressed down at both ends by the mating grooves.
