[0038] Hereinafter, an air conditioner 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0039] According to the air conditioner 100 of the embodiment of the present utility model, Figure 1 and Figure 2 As shown, the air conditioner 100 includes: a main body component 1, a fresh air component 2 and an electrical control box 3. The main body component 1 includes a heat exchange component 11, a fan component 12 and an air guide component 13. The length direction of the main body component 1 is the first direction F1; the fresh air component 2 and the main body component 1 are arranged along the first direction F1 to be located at one end of the length direction of the main body component 1; the electrical control box 3 is located between the main body component 1 and the fresh air component 2 along the first direction F1, and includes a box body 31 and a weak current board 33 arranged in the box body 31. At least part of the weak current working components in the main body component 1 and at least part of the weak current working components in the fresh air component 2 are electrically connected to the weak current board 33.

[0040] The main unit 1 includes a heat exchange assembly 11, a fan assembly 12, and an air guide assembly 13. The main unit 1 provides heat exchanged airflow to regulate the indoor temperature. The fresh air unit 2 is used to introduce outdoor fresh air to regulate the indoor temperature and air quality. The fresh air unit 2 is located at the upper end of the main unit 1 in its longitudinal direction. The neat arrangement of the fresh air unit 2 and the main unit 1 facilitates the compact design of the air conditioner 100.

[0041] The electrical control box 3 is electrically connected to the main unit 1 and the fresh air unit 2, respectively. The electrical control box 3 is used to control the operation of the heat exchange assembly 11, the fan assembly 12, the air guide assembly 13, and the fresh air unit 2. The electrical control box 3 includes a weak current board 33. At least some of the weak current operating components in the main unit 1 are electrically connected to the weak current board 33, illustratively via wires. At the same time, at least some of the weak current operating components in the fresh air unit 2 are electrically connected to the weak current board 33, illustratively via wires.

[0042] By arranging the electrical control box 3 between the main body component 1 and the fresh air component 2 along the first direction F1, the electrical connection between the electrical control box 3 and the main body component 1 is convenient, and the electrical connection between the electrical control box 3 and the fresh air component 2 is convenient. The wiring distance between the electrical control box 3 and the main body component 1 and the fresh air component 2 is short, the wiring is simple, the wiring harness occupies a small space, and is easy to arrange.

[0043] In addition, the main body 1, the electric control box 3 and the fresh air component 2 are arranged along the first direction F1. The main body 1, the electric control box 3 and the fresh air component 2 are arranged compactly and have regular shapes, which is conducive to the miniaturization design of the air conditioner 100 and facilitates the installation of the air conditioner 100.

[0044] According to the air conditioner 100 of the embodiment of the present invention, by arranging the electric control box 3 between the main body component 1 and the fresh air component 2, the main body component 1, the electric control box 3 and the fresh air component 2 are all arranged along the first direction F1, the electric control box 3 is conveniently electrically connected to the main body component 1 and the fresh air component 2 respectively, the wiring distance between the electric control box 3 and the main body component 1 and the fresh air component 2 is short, the wiring is simple and occupies little space, which is convenient for arrangement, and is conducive to realizing the miniaturization design of the air conditioner 100.

[0045] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the box body 31 is open on one side in the second direction F2 perpendicular to the first direction F1. The electric control box 3 also includes a box cover 32 covering the open side of the box body 31. The weak current board 33 has a connection terminal 331 on one side of the box cover 32.

[0046] The opening direction of the box body 31 is perpendicular to the first direction F1, and neither the main component 1 nor the fresh air component 2 interferes with the opening of the box body 31. The surface of the weak current board 33 facing the open side has a connection terminal 331. When the box body 31 is opened, the connection terminal 331 on the weak current board 33 can be directly connected to the wiring harness, which is easy to operate.

[0047] After the main component 1, the fresh air component 2 and the electric control box 3 are arranged, the electric control box 3 can be connected to the main component 1 and the fresh air component 2 respectively to improve assembly efficiency.

[0048] The electric control box 3 also includes a box cover 32, which is arranged on the open side of the box body 31 to enclose the weak current board 33 in the box body 31, and to limit at least part of the wiring harness connected to the weak current board 33 in the box body 31, thereby improving the regularity of the wiring harness.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air conditioner 100 is an on-hook air conditioner, the first direction F1 is the left-right direction, and the second direction F2 is the front-back direction. The front end of the box body 31 is open, and the front surface of the weak current board 33 has a connection terminal 331.

[0050] In some embodiments of the present invention, Figure 4 As shown, the side wall of the box body 31 is provided with a wire groove 31a connecting the inside and outside of the box body 31. The wire groove 31a is located at the end of the box body 31 close to the box cover 32, and has a wire entry port 31b open toward the box cover 32. The wire groove 31a is used to pass the wires connected to the weak current board 33.

[0051] The wire groove 31a extends through the side wall of the box body 31 along the thickness direction of the side wall, allowing wires to pass through the wire groove 31a from the outside of the box body 31 and extend into the box body 31 to connect to the weak current board 33. At least some of the weak current working components in the main body 1 extend into the box body 31 and connect to the weak current board 33 through wires passing through the wire groove 31a, and at least some of the weak current working components in the fresh air component 2 extend into the box body 31 and connect to the weak current board 33 through wires passing through the wire groove 31a. By providing the wire groove 31a on the side wall of the box body 31, the cooperation between the box body 31 and the box cover 32 will not interfere with the extension of the wires.

[0052] The wire groove 31a is arranged close to the box cover 32 to form a wire entry port 31b on the box body 31 that is open toward the box cover 32. After the wire is connected to the weak current board 33, it can directly enter the wire groove 31a from the wire entry port 31b in the direction away from the box cover 32, without having to connect the wire to the weak current board 33 and then pass through the wire groove 31a along the thickness direction of the side wall of the box body 31. The connection of the wire is simple and the operation is convenient.

[0053] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the box body 31 includes a first box wall 311 and a second box wall 312 spaced apart on both sides of the weak current board 33 along the first direction F1. The first box wall 311 is arranged on the side of the weak current board 33 close to the main body part 1, and at least one wire groove 31a is formed on the first box wall 311.

[0054] By providing a wire groove 31a on the first box wall 311, the wire groove 31a on the first box wall 311 is close to the main body part 1, which is beneficial to the connection between at least part of the weak current working parts in the main body part 1 and the weak current board 33, reduces the difficulty of wiring, and can reduce the space occupied by the wires, which is conducive to the miniaturization design of the air conditioner 100.

[0055] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the wire channel 31a formed on the first box wall 311 includes a first wire channel 31a1, through which a first wire harness 41 is passed. The first wire harness 41 includes at least one first ground wire 411. The first end of the first ground wire 411 is connected to the heat exchange assembly 11, and the second end of the first ground wire 411 is connected to the weak current board 33. The air conditioner 100 also includes a limiting structure. The limiting structure is provided on the side of the electric control box 3 near the heat exchange assembly 11 and cooperates with the first wire harness 41 to limit the position. The limiting structure is lower than the first end and the first wire channel 31a1.

[0056] The first wiring harness 41 passes through the first wire channel 31a1 and includes a first ground wire 411. The first ground wire 411 is connected between the heat exchange assembly 11 and the weak current board 33. Therefore, passing the first ground wire 411 through the first wire channel 31a1 on the first housing wall 311 facilitates the connection between the heat exchange assembly 11 and the weak current board 33. The second end of the first ground wire 411 is connected to the weak current board 33, while the first end of the first ground wire 411 is connected to the heat exchange assembly 11. This is then grounded through the heat exchange assembly 11, thereby grounding the weak current board 33. This protects the weak current board 33 from short circuits and leakage, thereby improving the safety of the air conditioner 100.

[0057] The air conditioner 100 also includes a limiting structure, which is used to constrain the first wiring harness 41. The first wiring harness 41 includes multiple wires. Therefore, by setting the limiting structure, the routing regularity of the first wiring harness 41 can be improved and the space occupied by the first wiring harness 41 can be reduced.

[0058] It is understandable that the first ground wire 411 in the first wiring harness 41 is connected to the heat exchange assembly 11, and condensed water will be generated on the heat exchange assembly 11. In order to prevent the condensed water from flowing along the first ground wire 411 to the weak current board 33, the embodiment of the present utility model is provided with a limiting structure. The limiting structure is lower than the first end of the first ground wire 411 and the first wire groove 31a1. The first end of the first ground wire 411 extends downward to the limiting structure, and the second end of the first ground wire 411 also extends downward to the limiting structure. In this way, even if condensed water flows from the heat exchange assembly 11 to the first ground wire 411, it will drip under the action of gravity at the lowest point where the limiting structure is located, and will not flow onto the weak current board 33, thereby improving the working safety of the electrical control box 3.

[0059] Optionally, the end of the heat exchange component 11 close to the first box wall 311 has a metal side plate, and the metal side plate is connected to the first end of the first ground wire 411. The metal side plate on the heat exchange component 11 is connected to the weak current plate 33 through the first ground wire 411, and the metal side plate on the heat exchange component 11 is grounded, so there is no need to set up additional metal grounding parts, which can save manufacturing costs and reduce layout difficulty.

[0060] In some embodiments of the present invention, Figure 5 As shown, the first wiring harness 41 also includes a wire 412 of a first temperature sensor for detecting the temperature of the heat exchange component 11, and the air conditioner 100 also includes a second temperature sensor for detecting the air duct temperature of the fresh air component 2. The terminal 331 includes a first terminal 3311, and the wire 412 of the first temperature sensor and the wire of the second temperature sensor are both connected to the first terminal 3311.

[0061] The wire 412 of the first temperature sensor and the wire of the second temperature sensor both pass through the first wire groove 31a1 and pass through the first box wall 311. The wire 412 of the first temperature sensor passes through the first wire groove 31a1 and is connected to the first terminal 3311. The wire of the second temperature sensor also passes through the first wire groove 31a1 and is connected to the first terminal 3311.

[0062] In some embodiments of the present invention, the first wiring terminal 3311 is a two-in-one terminal, and the first wiring terminal 3311 is connected to the wire 412 of the first temperature sensor and the wire of the second temperature sensor at the same time.

[0063] The first temperature sensor's wire 412 is connected between the heat exchange assembly 11 and the weak current board 33. Therefore, routing the first temperature sensor's wire 412 through the first wire slot 31a1 on the first enclosure wall 311 facilitates connection of the first temperature sensor. Furthermore, since the first terminal 3311 connects both the first temperature sensor's wire 412 and the second temperature sensor's wire, routing the second temperature sensor's wire through the first wire slot 31a1 on the first enclosure wall 311, along with the first temperature sensor's lead, improves wiring regularity.

[0064] In other embodiments of the present invention, there are two first wiring terminals 3311 , the wire 412 of the first temperature sensor is connected to one first wiring terminal 3311 , and the wire of the second temperature sensor is connected to the other first wiring terminal 3311 .

[0065] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the wire groove 31a formed on the first box wall 311 includes a second wire groove 31a2, a window 321 is provided on the box cover 32, the electric control box 3 includes a cover plate for covering the window 321, the wiring terminal 331 includes a second wiring terminal 3312 arranged opposite the window 321, the second wire groove 31a2 is located on the side of the window 321 and is connected to the window 321, the second wire harness 42 is passed through the second wire groove 31a2, and the second wire harness 42 is connected to the second wiring terminal 3312 through the window 321.

[0066] The second wire groove 31a2 is located at the end of the first box wall 311 close to the box cover 32, and the second wire groove 31a2 passes through the first box wall 311 toward the box cover 32 to form a wire entry 31b. Therefore, the second wire groove 31a2 is open toward the box cover 32 to communicate with the window 321 on the box cover 32. Figure 3 As shown, the dotted line indicates the opening position of the window 321. The opening on the box cover 32 is located near the first box wall 311. The second wiring harness 42 can directly pass through the window 321 and the second wire groove 31a2 along the opening direction of the box body 31 to connect with the second terminal 3312.

[0067] The second wiring harness 42 extends from the second terminal 3312 to the outside of the box body 31 and passes through the second wire groove 31a2 and the window 321. The second wire groove 31a2 can limit the second wiring harness 42 and improve the regularity of the routing of the second wiring harness 42.

[0068] In some embodiments of the present invention, Figure 2 As shown, the air conditioner 100 includes a face frame 5 and a panel 6. The panel 6 is openably mounted on the outside of the face frame 5. The face frame 5 defines an inspection area 51 that is positioned opposite the electrical control box 3. The inspection area 51 exposes the electrical control box 3, allowing direct repairs to the electrical control box 3 without removing the face frame 5, thereby facilitating subsequent maintenance.

[0069] The panel 6 has a display component 61, such as Figure 5 As shown, the second wiring harness 42 includes a wire 421 connected to the display assembly. For example, the display assembly 61 can be used to display information such as air temperature, humidity, and the mode of the air conditioner 100.

[0070] The panel 6 and the face frame 5 are located on the side of the electric control box 3 close to the first box wall 311 in the first direction F1, so the wires 421 connected to the display assembly are passed through the second wire groove 31a2 on the first box wall 311, which is conducive to the connection between the wires 421 connected to the display assembly and the weak current board 33. Figure 2As shown, the panel 6 and the face frame 5 are located on the side of the box cover 32 in the second direction F2 relative to the heat exchange component 11, so a window 321 is opened on the box cover 32 for the wire 421 connected to the display component to pass through, which is beneficial to the connection between the wire 421 connected to the display component and the weak current board 33.

[0071] In some embodiments of the present invention, the panel 6 has a magnet, and the face frame 5 is provided with a micro switch that cooperates with the magnet to detect the switch state of the panel 6, such as Figure 5 As shown, the second wiring harness 42 includes a wire 422 connected to the micro switch.

[0072] The cooperation between the micro switch and the magnet is to cut off the power to at least some of the terminal blocks 331 on the weak current board 33, so as to improve the safety of use. For example, the power terminal 331 connected to the fresh air purification module of the fresh air component 2 is in a live state during operation. When replacing or repairing the fresh air purification module, it is necessary to open the panel 6, that is, to separate the panel 6 from the face frame 5, and the micro switch on the panel 6 is also separated from the magnet on the face frame 5. At this time, the micro switch detects that the panel 6 is in the open state. The micro switch cuts off the power to the terminal block 331 connected to the fresh air purification module, thereby ensuring the safety of the replacement operation of the fresh air purification module.

[0073] Similarly, the panel 6 and the face frame 5 are located on the side of the electric control box 3 close to the first box wall 311 in the first direction F1, so the wire 422 connected to the micro switch passes through the second wire groove 31a2 on the first box wall 311, which is conducive to the connection between the wire 422 connected to the micro switch and the weak current board 33. Figure 2 As shown, the panel 6 and the face frame 5 are located on the side of the box cover 32 in the second direction F2 relative to the heat exchange component 11. Therefore, a window 321 is opened on the box cover 32 for the wire 422 connected to the micro switch to pass through, which is beneficial to the connection between the wire 422 connected to the micro switch and the low-voltage board 33.

[0074] In some embodiments of the present invention, Figure 5 As shown, the second wiring harness 42 includes a wire 421 connected to the display component, and the second wiring harness 42 also includes a wire 422 connected to the micro switch. There are two second wiring terminals 3312, the wire connected to the display component 61 is connected to one second wiring terminal 3312, and the wire 422 connected to the micro switch is connected to another second wiring terminal 3312.

[0075] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the box body 31 includes a first box wall 311 and a second box wall 312 spaced apart on both sides of the weak current board 33 along the first direction F1, and a third box wall 313 connecting the first box wall 311 and the second box wall 312. The third box wall 313 is arranged on one side of the weak current board 33 in the third direction F3. The third direction F3, the second direction F2 and the first direction F1 are perpendicular to each other. At least one wire groove 31a is formed on the third box wall 313.

[0076] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air conditioner 100 is an on-hook air conditioner, the first direction F1 is the left-right direction, the second direction F2 is the front-back direction, and the third direction F3 is the up-down direction. Figure 4 As shown, the third box wall 313 is provided on the lower side of the weak current board 33 .

[0077] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the wire passing groove 31a formed on the third box wall 313 includes a plurality of third wire passing grooves 31a3 arranged at intervals, the wiring terminal 331 includes an edge wiring terminal 3313, and at least two of the edge of the weak current board 33 close to the first box wall 311, the edge of the weak current board 33 close to the second box wall 312, and the edge of the weak current board 33 close to the third box wall 313 are provided with edge wiring terminals 3313, each third wire passing groove 31a3 is passed through by a third wiring harness 43, and the third wiring harness 43 is connected to the edge wiring terminal 3313.

[0078] By opening a third wire groove 31a3 on the third box wall 313, after connecting to the third wire harness 43 connected to the edge terminal 3313, a shorter wiring can be made inside the electric control box 3 and then extended from the electric control box 3, which can reduce the difficulty of connection, improve the regularity of wiring, and reduce the space occupied by the third wire harness 43 inside the electric control box 3, thereby improving the working stability of the electric control box 3 and helping to reduce the volume of the electric control box 3.

[0079] In some embodiments of the present invention, Figure 5 As shown, the edge of the weak current board 33 near the first box wall 311 is provided with an edge terminal 3313, the edge of the weak current board 33 near the second box wall 312 is provided with an edge terminal 3313, and the edge of the weak current board 33 near the third box wall 313 is also provided with an edge terminal 3313. There are two third wire ducts 31a3. The third wire harness 43 connected to the edge terminal 3313 near the first box wall 311 of the edge terminal 3313 is passed through the third wire duct 31a3 near the first box wall 311, and the third wire harness 43 connected to the edge terminal 3313 near the second box wall 312 of the edge terminal 3313 is passed through the third wire duct 31a3 near the second box wall 312.

[0080] In some embodiments of the present invention, Figure 5 As shown, there are two third cable ducts 31a3: one relatively close to the first box wall 311, that is, close to the main unit 1, and the other close to the second box wall 312, that is, close to the fresh air unit 2. The third wiring harness 43, which runs through the third cable duct 31a3 on the side closest to the main unit 1, includes a main unit sterilization module connection cable 431, a fresh air purification module connection cable 432, and a main unit external air guide plate connection cable 433.

[0081] like Figure 5 As shown, the main body sterilization module of the fan assembly 12 is connected to the edge terminal 3313 of the weak current board 33 near the first box wall 311 via the main body sterilization module connection line 431, which is installed through the third wire groove 31a3 on the side near the main body 1. The fresh air purification module of the fresh air assembly is connected to the edge terminal 3313 of the weak current board 33 near the first box wall 311 via the fresh air purification module connection line 432, which is installed through the third wire groove 31a3 on the side near the main body 1. The main body outer air deflector of the air guide assembly 13 is connected to the edge terminal 3313 of the weak current board 33 near the first box wall 311 via the main body outer air deflector connection line 433, which is installed through the third wire groove 31a3 on the side near the main body 1. The edge terminal 3313 connected to the main body sterilization module connection line 431, the fresh air purification module connection line 432, and the main body outer air deflector connection line 433 are arranged in sequence in the direction close to the third box wall 313 in the third direction F3.

[0082] Illustratively, the main body sterilization module is a part of the main body component 1 and can be located upstream or downstream of the heat exchange component 11. The main body sterilization module is used to sterilize the air flowing through the heat exchange component 11 to improve the cleanliness of the airflow.

[0083] Exemplarily, the fresh air purification module is a part of the fresh air component 2, which is used to filter and sterilize the outdoor fresh air to improve the quality of the fresh air. Optionally, the fresh air purification module can include a fresh air filter.

[0084] Exemplarily, the outer air guide plate of the main body is part of the air guide assembly 13, which is arranged at the main air outlet of the air conditioner to adjust the air outlet direction of the air conditioner 100, and can also be used as a switch door to open or close the main air outlet of the air conditioner 100.

[0085] like Figure 5As shown, the main body longitudinal swing air mechanism is connected to the edge connection terminal 3313 of the weak-current board 33 near the third box wall 313 via the main body longitudinal swing air mechanism connection line 436, which is provided through the third wire groove 31a3 on the side near the fresh air component 2. The main body transverse swing air mechanism is connected to the edge connection terminal 3313 of the weak-current board 33 near the third box wall 313 via the main body transverse swing air mechanism connection line 437, which is provided through the third wire groove 31a3 on the side near the fresh air component 2. The edge connection terminals 3313 connected to the main body longitudinal swing air mechanism connection line 436 and the main body transverse swing air mechanism connection line 437 are arranged sequentially from the first box wall 311 to the second box wall 312 in the first direction F1.

[0086] Illustratively, the main body longitudinal swing wind mechanism and the main body transverse swing wind mechanism are both part of the main body component 1. The main body longitudinal swing wind mechanism includes air guide bars extending in a direction parallel to the axial direction of the crossflow wind wheel 121, and the main body transverse swing wind mechanism includes air guide bars extending perpendicular to the axial direction of the crossflow wind wheel 121. The main body longitudinal swing wind mechanism connection line 436 is connected to the main body longitudinal swing wind mechanism's drive motor, and the main body transverse swing wind mechanism connection line 437 is connected to the main body transverse swing wind mechanism's drive motor.

[0087] like Figure 5 As shown, the fresh air fan of the fresh air assembly is connected to the edge terminal 3313 of the weak current board 33 near the second box wall 312 via a fresh air fan connection line 434 that passes through the third wire duct 31a3 near the side of the fresh air component 2. The fresh air inlet valve of the fresh air assembly is connected to the edge terminal 3313 of the weak current board 33 near the second box wall 312 via a fresh air inlet valve connection line 435 that passes through the third wire duct 31a3 near the side of the fresh air component 2. The edge terminal 3313 connected to the fresh air fan connection line 434 and the fresh air inlet valve connection line 435 are arranged sequentially in the direction close to the third box wall 313 in the third direction F3.

[0088] Exemplarily, the fresh air blower is a part of the fresh air component 2 and is used to introduce outdoor air into the room.

[0089] Illustratively, the fresh air inlet valve is a part of the fresh air component 2 and is used to control whether fresh air circulates. When closed, it can prevent external pollutants from entering the fresh air component 2.

[0090] In some embodiments of the present invention, Figure 1-Figure 3As shown, the air conditioner 100 is a wall mounted air conditioner, the first direction F1 is the left-right direction, the box cover 32 is arranged on the front side of the box body 31, the fan assembly 12 includes a cross flow fan wheel 121 and a drive motor 122, the axial direction of the cross flow fan wheel 121 is the first direction F1, the drive motor 122 is connected to the side of the cross flow fan wheel 121 close to the fresh air component 2, at least part of the drive motor 122 and / or at least part of the fresh air component 2 are matched with the electric control box 3 to avoid air so as to be located behind the box cover 32.

[0091] That is, the electrical control box 3 defines an air-avoidance space 3a, and at least a portion of the drive motor 122 and / or at least a portion of the fresh air component 2 occupies the air-avoidance space 3a, allowing at least a portion of the drive motor 122 and / or at least a portion of the fresh air component 2 to intrude into the boundary area occupied by the electrical control box 3 in the first direction F1. As a result, the stacking length L of the fan assembly 12, the electrical control box 3, and the fresh air component 2 along the first direction F1 is less than the sum of the lengths of the fan assembly 12, the electrical control box 3, and the fresh air component 2 along the first direction F1. Thus, the length of the air conditioner 100 along the first direction F1 can be reduced, facilitating a compact design of the air conditioner 100 for easier installation.

[0092] "The boundary area occupied by the electrical control box 3 in the first direction F1" can be understood as: the area between the first plane and the second plane, wherein the first plane and the second plane are both perpendicular to the first direction F1, the first plane is the plane passing through the point on the electrical control box 3 that is farthest from the fresh air component 2 in the first direction F1, and the second plane is the plane passing through the point on the electrical control box 3 that is farthest from the fan assembly 12 in the first direction F1, so that the box body 31 as a whole can be completely located between the first plane and the second plane, or in other words, the first plane and the second plane are the two planes in the plane perpendicular to the first direction F1 that can accommodate the box body 31 and are the closest to each other.

[0093] For example, the air conditioner 100 is a wall mounted air conditioner, the front end of the box body 31 is open to form an open opening, the weak current board 33 can be loaded backwards into the box body 31 from the open opening, the box cover 32 is provided on the front side of the box body 31 to enclose the circuit board in the weak current board 33, and the portion of the drive motor 122 and / or the fresh air component 22 that fits with the electric control box 3 to avoid air is located behind the box cover 32, that is, the box cover 32 blocks the front side of the portion of the drive motor 122 and / or the fresh air component 2 that fits with the electric control box 3 to avoid air. It is worth noting here that there may be at least a portion of the box body 31 between the portion of the drive motor 122 and / or the fresh air component 2 that fits with the electric control box 3 to avoid air and the box cover 32, or there may not be at least a portion of the box body 31 between the box cover 32.

[0094] Therefore, under the premise of avoiding the driving motor 122 and / or the fresh air component 22, the box cover 32 can be exposed to facilitate opening the box cover 32 to inspect the interior of the electric control box 3.

[0095] In some embodiments of the present invention, Figure 3 As shown, the box body 31 includes a first box part 31c and a second box part 31d. The size of the first box part 31c in the front-to-back direction is larger than the size of the second box part 31d in the front-to-back direction. The second box part 31d is arranged below the first box part 31c, and the second box part 31d is arranged corresponding to the front end of the first box part 31c. The front ends of the first box part 31c and the second box part 31d are both open to be opened and closed by the box cover 32.

[0096] like Figure 4 and Figure 6 As shown, the electric control box 3 includes a high-current board 34 arranged in the first box part 31c. The length direction of the high-current board 34 extends along the front-to-back direction, and the two sides in the thickness direction are respectively facing the main part 1 and the fresh air part 2. The low-current board 33 is arranged in the second box part 31d, and the thickness direction of the low-current board 33 is the front-to-back direction. The part where the drive motor 122 and / or the fresh air part 2 is matched with the box body 31 to avoid air is located below the first box part 31c and behind the second box part 31d.

[0097] Therefore, through the above-mentioned setting, the space of the air conditioner 100 along the up and down directions and the front and back directions can be fully utilized, which is beneficial to reducing the space occupied by the electric control box 3 along the left and right directions, helping to reduce the overall size of the air conditioner 100, and helping to improve the space utilization rate of the air conditioner 100, thereby realizing the miniaturization design of the air conditioner 100.

[0098] Furthermore, through the above arrangement, the electric control box 3 can accommodate both the high-current board 34 and the low-current board 33 simultaneously, and interference between the high-current board 34 and the low-current board 33 can be avoided, thereby improving the reliability of the electric control box 3. Furthermore, the front end of the box body 31 is open to form an opening, and both the high-current board 34 and the low-current board 33 can be inserted backwards into the box body 31 through the opening. The box cover 32 is provided on the front side of the box body 31 to enclose both the high-current board 34 and the low-current board 33 within the box body 31, thereby improving assembly convenience.

[0099] For example, the first box portion 31c can be configured to be a flat box with a height smaller than its length and width, the length of the first box portion 31c being the front-to-back direction, the width of the first box portion 31c being the top-to-bottom direction, the height of the first box portion 31c being the left-to-right direction, and the length, width, and thickness of the strong current board 34 being consistent with the length, width, and height of the first box portion 31c. Simultaneously, the second box portion 31d can be configured to be a flat box with a height smaller than its length and width, the height of the second box portion 31d being the front-to-back direction, the width of the second box portion 31d being the left-to-right direction, the length of the second box portion 31d being the top-to-bottom direction, and the length, width, and thickness of the weak current board 33 being consistent with the length, width, and height of the second box portion 31d.

[0100] Through the above-mentioned arrangement, the air-avoidance space 3a formed behind the second box portion 31d can be made larger, so that at least part of the fresh air component 2 and at least part of the fan assembly 12 can be better placed in the air-avoidance space 3a, which is beneficial to improving the space utilization of the air conditioner 100 and reducing the overall size of the air conditioner 100.

[0101] In some embodiments of the present invention, Figure 4 As shown, a plurality of wire-clamping openings 31e are penetrated on one side wall of the first box portion 31c close to the fan assembly 12, and the plurality of wire-clamping openings 31e are spaced apart in the up-down direction. The air conditioner 100 includes electric auxiliary heating, and the fan wire 45 connected to the fan assembly 12 and the electric auxiliary heating wire 46 connected to the electric auxiliary heating extend into the first box portion 31c through different wire-clamping openings 31e respectively to be connected to the strong current board 34 respectively.

[0102] For example, multiple clamping ports 31e are spaced apart in the vertical direction. The air conditioner 100 includes electric auxiliary heating, which can be used to heat the conditioned air blown out by the fan assembly 12. The power line includes an electric auxiliary heating line 46 and a fan line 45. The electric auxiliary heating is connected to the electric auxiliary heating line 46, and the fan assembly 12 is connected to the fan line 45. Among them, the clamping port 31e is located at the end of the box body 31 close to the box cover 32 and is open toward the box cover 32. The fan line 45 and the electric auxiliary heating line 46 can be respectively clamped into different clamping ports 31e from the open end to pass through the wall of the first box part 31c, so that the fan line 45 and the electric auxiliary heating line 46 can extend into the first box body 31 to connect to the power board 34, so that the electric control box 3 can supply power to the fan assembly 12 and the electric auxiliary heating through the power board 34. It is understandable that by setting the fan line 45 and the electric auxiliary heating line 46 to be clamped in different clamping openings 31e, the risk of wire compression can be eliminated, the stability of the electric control box 3 can be improved, and the reliability of the air conditioner 100 can be improved.

[0103] Exemplarily, the housing 31 includes a stopper 35 located on a side of the first housing portion 31c proximal to the fan assembly 12. At least a portion of the stopper 35 is spaced from the first housing portion 31c, forming a wire-accommodating space 36 between the stopper 35 and the first housing portion 31c. The wire-accommodating space 36 can accommodate the power cables routed through the cable opening 31e. It should be noted that the power cables include the fan cable 45 and the auxiliary heating cable 46.

[0104] Air conditioner 100 includes a fan assembly 12 and a heat exchange assembly 11. Fresh air unit 2 and electrical control box 3 are located either to the left or to the right of heat exchange assembly 11. A refrigerant pipeline is connected to heat exchange assembly 11. This pipeline is located on the side of heat exchange assembly 11 near electrical control box 3. Heat exchange assembly 11 exchanges heat with conditioned air through the refrigerant pipeline, allowing the conditioned air to cool or heat the indoor space.

[0105] The stopper 35 can be located between the wire accommodating space 36 and the refrigerant pipeline. When condensed water forms on the outer wall of the refrigerant pipeline, the stopper 35 can prevent the condensed water from flowing toward the power line.

[0106] It can be understood that the wire accommodating space 36 can be used to accommodate the excess part of the strong wire to eliminate the wire length error of the strong wire and ensure the precise installation of the strong wire. The stopper 35 can prevent condensed water from flowing along the strong wire and causing danger, thereby improving the safety of the air conditioner 100.

[0107] In some embodiments of the present invention, Figure 4 As shown, there are two wire-holding openings 31e, which are respectively located at the upper and lower ends of the first box wall 311 and both penetrate in the left-right direction. The stopper 35 is constructed as an elastic buckle 35a. The two elastic buckles 35a are spaced apart in the up-down direction to form a wire-passing opening 35b between the two elastic buckles 35a. The wire-passing opening 35b is located between the two wire-holding openings 31e in the up-down direction. The fan wire 45 is suitable for entering the wire-holding space 36 through the wire-passing opening 35b and passing upward into the wire-holding opening 31e at the upper end. The electric auxiliary heating wire 46 is suitable for entering the wire-holding space 36 through the wire-passing opening 35b and passing downward into the wire-holding opening 31e at the lower end.

[0108] For example, refer to Figure 4 As shown, two wire-locking openings 31e can be provided, the two wire-locking openings 31e being located at the upper and lower ends of the first box wall 311, respectively, and both wire-locking openings 31e passing through the side wall of the first box portion 31c in the left-right direction. The stopper 35 includes two elastic buckles 35a, which are spaced apart in the vertical direction to form a wire-passing opening 35b between the two elastic buckles 35a. The wire-passing opening 35b is connected to the wire-accommodating space 36, allowing the fan wire 45 and the electric auxiliary heating wire 46 to enter the wire-accommodating space 36 through the wire-passing opening 35b. The wire-accommodating space 36 is connected to the wire-locking opening 31e, and the fan wire 45 and the electric auxiliary heating wire 46 entering the wire-accommodating space 36 can be respectively installed in the corresponding wire-locking openings 31e.

[0109] In some embodiments of the present invention, Figure 4 As shown, a wire hole 31f is provided on the side wall of the first box part 31c away from the fan assembly 12, and the wire hole 31f connects the inside and outside of the first box part 31c. The high-voltage electrical wire harness including at least one of the power cord 47 and the indoor and outdoor unit connecting wire 48 is passed through the wire hole 31f to be connected to the high-voltage board 34.

[0110] Exemplarily, the power cord 47 and the indoor and outdoor unit connecting wire 48 are both passed through the wire hole 31f and electrically connected to the high-voltage board 34. The external power supply can supply power to the high-voltage board 34 through the power cord 47, and the high-voltage board 34 can supply power to the air conditioner outdoor unit through the indoor and outdoor unit connecting wire 48.

[0111] For example, Figure 4 and Figure 6 As shown, in the specific installation process, first connect the power cord 47 and the indoor and outdoor unit connecting wires 48 to the strong power board 34, and pull the fan wire 45 and the electric auxiliary heating wire 46 to the front side of the box body 31; then, the strong power board 34 can be installed in the first box part 31c from front to back; then, the power cord 47 and the indoor and outdoor unit connecting wires 48 can be inserted into the wire threading hole 31f from the right side of the box body 31; then, the fan wire 45 and the electric auxiliary heating wire 46 can be inserted into the wire accommodating space 36 through the wire passing port 35b from the left side of the box body 31 and connected to the strong power board 34; finally, the fan wire 45 can be pulled upward along the wire accommodating space 36 to pass through the wire clamping port 31e at the upper end, and the electric auxiliary heating wire 46 can be pulled downward along the wire accommodating space 36 to pass through the wire clamping port 31e at the lower end, so as to realize the line arrangement of the strong power board 34.

[0112] Through the above-mentioned arrangement, the fan line 45 and the electric auxiliary heating line 46 entering the line accommodating space 36 can be kept parallel to the line clamping opening 31e, so that the fan line 45 and the electric auxiliary heating line 46 can be more easily clamped into the corresponding line clamping opening 31e, thereby reducing the assembly difficulty of the air conditioner 100, and avoiding the fan line 45 and the electric auxiliary heating line 46 from being intertwined, thereby improving the design rationality of the air conditioner 100.

[0113] In some embodiments of the present invention, Figure 5 As shown, the connection terminal 331 includes a third connection terminal 3314 provided on the upper portion of the weak current board 33 , and the strong and weak current board connection line 49 connecting the strong current board 34 and the weak current board 33 is connected to the third connection terminal 3314 .

[0114] In this way, the electrical connection between the strong current board 34 and the weak current board 33 can be simply and effectively achieved, thereby realizing power supply.

[0115] In some embodiments of the present invention, Figure 5 As shown, there are two first ground wires 411, extending from the first wire duct 31a1. The first wiring harness 41 also includes at least two second ground wires 413, the first ends of which are connected to the heat exchange assembly 11, and the second ends of which are connected to the high-voltage board 34. A retaining structure cooperates with the first wiring harness 41 to limit the position of the first wiring harness 41, and the retaining structure is lower than the first end and the first wire duct 31a1.
