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

[0039] An air conditioner 100 according to an embodiment of the present invention, such as 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 assembly 11, a fan assembly 12, and an air guide assembly 13. The length direction of the main body component 1 is a first direction F1. The fresh air component 2 is arranged with the main body component 1 along the first direction F1 and is 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 low-voltage board 33 disposed in the box body 31. At least some of the low-voltage working components in the main body component 1 and at least some of the low-voltage working components in the fresh air component 2 are electrically connected to the low-voltage board 33.

[0040] The main component 1 includes a heat exchange assembly 11, a fan assembly 12, and an air guide assembly 13. The main component 1 provides airflow after heat exchange to regulate the indoor temperature. The fresh air component 2 is used to introduce fresh outdoor air, which can regulate the indoor temperature and indoor air quality. The fresh air component 2 is located at the upper end of the main component 1 along its length. The regular arrangement of the fresh air component 2 and the main component 1 is conducive to the miniaturization design of the air conditioner 100.

[0041] The electrical control box 3 is electrically connected to both the main body component 1 and the fresh air component 2. The electrical control box 3 controls the operation of the heat exchange assembly 11, the fan assembly 12, the air guide assembly 13, and the fresh air component 2. The electrical control box 3 includes a low-voltage board 33. At least some of the low-voltage operating components in the main body component 1 are electrically connected to the low-voltage board 33, exemplarily via wires; similarly, at least some of the low-voltage operating components in the fresh air component 2 are electrically connected to the low-voltage board 33, exemplarily 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. At the same time, the electrical connection between the electrical control box 3 and the fresh air component 2 is also 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 space occupied by the wiring harness is small, and it is easy to arrange.

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

[0044] According to an embodiment of the present invention, the air conditioner 100 arranges the electrical control box 3 between the main body component 1 and the fresh air component 2. The main body component 1, the electrical control box 3 and the fresh air component 2 are all arranged along the first direction F1. The electrical control box 3 is convenient to be electrically connected to the main body component 1 and the fresh air component 2 respectively. 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 and occupies little space, which is convenient for the arrangement and helps to realize the miniaturization design of the air conditioner 100.

[0045] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the box body 31 is open on one side in the second direction F2, which is perpendicular to the first direction F1. The electrical control box 3 also includes a cover 32 that covers the open side of the box body 31. The surface of the low voltage board 33 facing the cover 32 has a wiring terminal 331.

[0046] The opening direction of the housing 31 is perpendicular to the first direction F1, and neither the main body component 1 nor the fresh air component 2 will interfere with the opening of the housing 31. The surface of the low-voltage board 33 facing the open side has wiring terminals 331. By opening the housing 31, the wiring harness can be directly connected to the wiring terminals 331 on the low-voltage board 33, which is simple to operate.

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

[0048] The electrical control box 3 also includes a cover 32, which is located on the open side of the box body 31 to enclose the low voltage board 33 inside the box body 31 and to limit at least a portion of the wiring harness connected to the low voltage board 33 inside the box body 31, thereby improving the neatness of the wiring harness.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the air conditioner 100 is a wall-mounted 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 housing 31 is open, and the front surface of the low-voltage board 33 has wiring terminals 331.

[0050] In some embodiments of the present invention, such as Figure 4 As shown, the side wall of the box 31 is provided with a wire passage groove 31a that connects the inside and outside of the box 31. The wire passage groove 31a is located at the end of the box 31 near the box cover 32 and has a wire inlet 31b that opens towards the box cover 32. The wire passage groove 31a is used to pass through the wires connected to the low voltage board 33.

[0051] The cable tray 31a extends through the side wall of the box 31 along the thickness direction of the side wall, allowing wires to pass through the cable tray 31a from the outside of the box 31 and extend into the box 31 to connect with the low-voltage board 33. At least some of the low-voltage working components in the main body component 1 extend into the box 31 and connect with the low-voltage board 33 through the cable tray 31a, and at least some of the low-voltage working components in the fresh air component 2 extend into the box 31 and connect with the low-voltage board 33 through the cable tray 31a. By opening the cable tray 31a on the side wall of the box 31, the fit between the box 31 and the cover 32 will not interfere with the extension of the wires.

[0052] The cable tray 31a is located near the cover 32, so that an inlet 31b is formed on the box body 31 that opens towards the cover 32. After the wire is connected to the low voltage board 33, it can directly enter the cable tray 31a from the inlet 31b in a direction away from the cover 32, without having to connect the wire to the low voltage board 33 and then pass through the cable tray 31a along the thickness 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, such as Figure 4 and Figure 5 As shown, the box body 31 includes a first box wall 311 and a second box wall 312 that are spaced apart on both sides of the low voltage board 33 along the first direction F1. The first box wall 311 is located on the side of the low voltage board 33 near the main body component 1, and at least one wire groove 31a is formed on the first box wall 311.

[0054] By providing a wire channel 31a on the first box wall 311, the wire channel 31a on the first box wall 311 is closer to the main body component 1, which is conducive to the connection of at least some of the low-voltage working components in the main body component 1 with the low-voltage board 33, reducing the difficulty of wiring, reducing the space occupied by the wires, and facilitating the miniaturization design of the air conditioner 100.

[0055] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the wiring trough 31a formed on the first box wall 311 includes a first wiring trough 31a1, through which a first wire harness 41 passes. 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 low-voltage board 33. The air conditioner 100 also includes a limiting structure, which is located outside the control box 3 on the side near the heat exchange assembly 11 and cooperates with the limiting structure of the first wire harness 41. The limiting structure is lower than the first end and the first wiring trough 31a1.

[0056] The first wiring harness 41 passes through the first wiring groove 31a1. The first wiring harness 41 includes a first ground wire 411, which connects the heat exchange assembly 11 and the low-voltage board 33. Therefore, passing the first ground wire 411 through the first wiring groove 31a1 on the first box wall 311 facilitates the connection between the heat exchange assembly 11 and the low-voltage board 33. The second end of the first ground wire 411 is connected to the low-voltage board 33, and the first end of the first ground wire 411 is connected to the heat exchange assembly 11. The heat exchange assembly 11 is then grounded, thereby grounding the low-voltage board 33. This protects the low-voltage board 33 in the event of a short circuit or leakage, 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 wiring 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 understood that the first ground wire 411 in the first wiring harness 41 is connected to the heat exchange component 11, and condensation will be generated on the heat exchange component 11. To prevent condensation from flowing along the first ground wire 411 to the low-voltage board 33, this embodiment of the invention provides 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 condensation flows from the heat exchange component 11 to the first ground wire 411, it will drip down under the action of gravity at the lowest point where the limiting structure is located, and will not flow onto the low-voltage board 33, thereby improving the operational safety of the electrical control box 3.

[0059] Optionally, the end of the heat exchange assembly 11 near the first box wall 311 has a metal side plate. The metal side plate is connected to the first end of the first ground wire 411. The metal side plate on the heat exchange assembly 11 is connected to the low voltage board 33 through the first ground wire 411, and the metal side plate on the heat exchange assembly 11 is grounded. Therefore, it is not necessary to set up an additional metal grounding component, which can save manufacturing costs and reduce the difficulty of layout.

[0060] In some embodiments of the present invention, such as Figure 5 As shown, the first wiring harness 41 also includes a wire 412 for a first temperature sensor used to detect the temperature of the heat exchange component 11, and the air conditioner 100 also includes a second temperature sensor used to detect the duct temperature of the fresh air component 2. The terminal block 331 includes a first terminal block 3311, and the wires 412 of the first temperature sensor and the wires of the second temperature sensor are both connected to the first terminal block 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 through the first box wall 311. After passing through the first wire groove 31a1, the wire 412 of the first temperature sensor 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 terminal 3311 is a single terminal that is also a two-in-one terminal, and the first terminal 3311 is simultaneously connected to the wire 412 of the first temperature sensor and the wire of the second temperature sensor.

[0063] The wire 412 of the first temperature sensor is connected between the heat exchange assembly 11 and the low-voltage board 33. Therefore, passing the wire 412 of the first temperature sensor through the first wire channel 31a1 on the first housing wall 311 is beneficial for the connection of the first temperature sensor. Since the first terminal 3311 connects the wire 412 of the first temperature sensor and the wire of the second temperature sensor, passing the wire of the second temperature sensor through the first wire channel 31a1 on the first housing wall 311 along with the guide of the first temperature sensor can improve the neatness of the wiring.

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

[0065] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the wire channel 31a formed on the first box wall 311 includes a second wire channel 31a2. The box cover 32 has a window 321. The electrical control box 3 includes a cover plate for covering the window 321. The terminal block 331 includes a second terminal block 3312 that is directly opposite to the window 321. The second wire channel 31a2 is located on the side of the window 321 and communicates with the window 321. A second wire harness 42 passes through the second wire channel 31a2. The second wire harness 42 is connected to the second terminal block 3312 through the window 321.

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

[0067] The second wiring harness 42 extends from the second terminal 3312 outward from the housing 31 and passes through the second wire channel 31a2 and the window 321. The second wire channel 31a2 can limit the second wiring harness 42 and improve the neatness of the wiring of the second wiring harness 42.

[0068] In some embodiments of the present invention, such as Figure 2 As shown, the air conditioner 100 includes a front frame 5 and a panel 6. The panel 6 is switchably disposed on the outside of the front frame 5. The front frame 5 has a maintenance area 51 disposed opposite to the electrical control box 3. The maintenance area 51 exposes the electrical control box 3, allowing for direct maintenance of the electrical control box 3 without removing the front frame 5, thus facilitating subsequent maintenance.

[0069] Panel 6 has a display component 61, such as Figure 5 As shown, the second wiring harness 42 includes wires 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] Panel 6 and frame 5 are located on the side of electrical control box 3 in the first direction F1, close to the first box wall 311. Therefore, the wire 421 connected to the display component passes through the second wire channel 31a2 on the first box wall 311, which facilitates the connection of the wire 421 connected to the display component to the low-voltage board 33. Figure 2As shown, the panel 6 and the frame 5 are located on the side of the second direction F2 near the cover 32 relative to the heat exchange assembly 11. Therefore, a window 321 is provided on the cover 32 for the wires 421 connected to the display assembly to pass through, which is beneficial for the connection of the wires 421 connected to the display assembly to the low voltage board 33.

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

[0072] The combined function of the microswitch and the magnet is to de-energize at least some of the terminals 331 on the low-voltage board 33, thereby improving safety. For example, the terminals 331 connected to the fresh air purification module of the fresh air component 2 are energized during operation. When replacing or repairing the fresh air purification module, the panel 6 needs to be opened, i.e., the panel 6 is separated from the frame 5. The microswitch on the panel 6 also separates from the magnet on the frame 5. At this time, the microswitch detects that the panel 6 is in the open state. The microswitch de-energizes the terminals 331 connected to the fresh air purification module, thus ensuring the safety of replacing the fresh air purification module.

[0073] Similarly, panel 6 and frame 5 are located on the side of electrical control box 3 near the first box wall 311 in the first direction F1. Therefore, the wire 422 connected to the micro switch is passed through the second wire channel 31a2 on the first box wall 311, which facilitates the connection of the wire 422 connected to the micro switch to the low-voltage board 33. Figure 2 As shown, the panel 6 and the frame 5 are located on the side of the heat exchange assembly 11 in the second direction F2, close to the cover 32. Therefore, a window 321 is provided on the cover 32 for the wire 422 connected to the micro switch to pass through, which is beneficial for the connection of the wire 422 connected to the micro switch to the low voltage board 33.

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

[0075] In some embodiments of the present invention, such as 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 low voltage 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 located on one side of the low voltage board 33 on 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, such as Figure 1 and Figure 2 As shown, air conditioner 100 is a wall-mounted air conditioner. The first direction F1 is left-right, the second direction F2 is front-back, and the third direction F3 is up-down. Figure 4 As shown, the third box wall 313 is located on the lower side of the low voltage board 33.

[0077] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the cable tray 31a formed on the third box wall 313 includes a plurality of third cable trays 31a3 spaced apart. The terminal block 331 includes an edge terminal block 3313. The edge terminal block 3313 is provided at least two of the edges of the low voltage board 33 near the first box wall 311, the edge of the low voltage board 33 near the second box wall 312, and the edge of the low voltage board 33 near the third box wall 313. Each third cable tray 31a3 is provided with a third wire harness 43, and the third wire harness 43 is connected to the edge terminal block 3313.

[0078] By opening a third wire passage 31a3 on the third box wall 313 and connecting it to the third wire harness 43 connected to the edge terminal 3313, a shorter wire can be routed inside the electrical control box 3 to extend out of the electrical control box 3. This reduces the difficulty of wiring, improves the neatness of the wiring, and reduces the space occupied by the third wire harness 43 inside the electrical control box 3, thereby improving the working stability of the electrical control box 3 and helping to reduce the size of the electrical control box 3.

[0079] In some embodiments of the present invention, such as Figure 5 As shown, the low-voltage board 33 has an edge terminal block 3313 near the first box wall 311, an edge terminal block 3313 near the second box wall 312, and an edge terminal block 3313 near the third box wall 313. There are two third wire passages 31a3. The third wire harness 43 connected to the edge terminal block 3313 near the first box wall 311 passes through the third wire passage 31a3 near the first box wall 311, and the third wire harness 43 connected to the edge terminal block 3313 near the second box wall 312 passes through the third wire passage 31a3 near the second box wall 312.

[0080] In some embodiments of the present invention, such as Figure 5 As shown, there are two third cable trays 31a3. One is located relatively close to the first box wall 311, i.e., close to the main body component 1, and the other is located close to the second box wall 312, i.e., close to the fresh air component 2. The third wiring harness 43 passing through the third cable tray 31a3 on the side close to the main body component 1 includes a main body sterilization module connection wire 431, a fresh air purification module connection wire 432, and a main body external air guide plate connection wire 433. The third wiring harness 43 passing through the third cable tray 31a3 on the side close to the fresh air component 2 includes a fresh air fan connection wire 434, a fresh air inlet valve connection wire 435, a main body longitudinal swing air mechanism connection wire 436, and a main body transverse swing air mechanism connection wire 437.

[0081] like Figure 5 As shown, the main sterilization module of the fan assembly 12 is connected to the edge terminal 3313 of the low-voltage board 33 near the first box wall 313 via the main sterilization module connecting line 431, which passes through the third wiring groove 31a3 near the main component 1. The fresh air purification module of the fresh air assembly is connected to the edge terminal 3313 of the low-voltage board 33 near the first box wall 313 via the fresh air purification module connecting line 432, which passes through the third wiring groove 31a3 near the main component 1. The air guide plate of the main body of the air guide assembly 13 is connected to the edge terminal 3313 of the low-voltage board 33 near the first box wall 313 via the main body outer air guide plate connecting line 433, which passes through the third wiring groove 31a3 near the main component 1. The edge terminal 3313 connected to the main sterilization module connecting line 431, the fresh air purification module connecting line 432, and the main body outer air guide plate connecting line 433 are arranged sequentially on the third direction F3 towards the direction near the third box wall 313.

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

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

[0084] For example, the main body external air guide plate is part of the air guide assembly 13 and is set at the main air outlet of the air conditioner. It is used to adjust the air outlet direction of the air conditioner 100 and can also be used as a door to open or close the main air outlet of the air conditioner 100.

[0085] like Figure 5As shown, the main longitudinal oscillating air mechanism passes through the third cable tray 31a3 near the fresh air component 2 via the main longitudinal oscillating air mechanism connecting line 436, and is connected to the edge terminal 3313 of the low-voltage board 33 near the third box wall 313; the main transverse oscillating air mechanism passes through the third cable tray 31a3 near the fresh air component 2 via the main transverse oscillating air mechanism connecting line 437, and is connected to the edge terminal 3313 of the low-voltage board 33 near the third box wall 313. The edge terminal 3313 connected to the main longitudinal oscillating air mechanism connecting line 436 and the main transverse oscillating air mechanism connecting line 437 are sequentially arranged along the direction from the first box wall 311 to the second box wall 312 in the first direction F1.

[0086] For example, both the main longitudinal oscillation mechanism and the main transverse oscillation mechanism are part of the main body component 1. The main longitudinal oscillation mechanism includes air guides extending in a direction parallel to the axial direction of the cross-flow impeller 121, and the main transverse oscillation mechanism includes air guides extending in a direction perpendicular to the axial direction of the cross-flow impeller 121. The main longitudinal oscillation mechanism connecting line 436 is connected to the drive motor of the main longitudinal oscillation mechanism, and the main transverse oscillation mechanism connecting line 437 is connected to the drive motor of the main transverse oscillation mechanism.

[0087] like Figure 5 As shown, the fresh air fan of the fresh air assembly passes through the third cable tray 31a3 near the fresh air component 2 via a fresh air fan connection cable 434, and is connected to the edge terminal 3313 of the low-voltage board 33 near the second box wall 312. The fresh air inlet valve of the fresh air assembly passes through the third cable tray 31a3 near the fresh air component 2 via a fresh air inlet valve connection cable 435, and is connected to the edge terminal 3313 of the low-voltage board 33 near the second box wall 312. The edge terminal 3313 connected to the fresh air fan connection cable 434 and the fresh air inlet valve connection cable 435 are sequentially arranged on the third direction F3 towards the direction near the third box wall 313.

[0088] For example, the fresh air fan is part of the fresh air component 2 and is used to introduce outdoor airflow into the room.

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

[0090] In some embodiments of the present invention, such as Figures 1-3As shown, the air conditioner 100 is a wall-mounted air conditioner, the first direction F1 is the left and right direction, the cover 32 is installed 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 axis 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 near 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 in a non-empty fit with the electrical control box 3 so as to be located behind the cover 32.

[0091] That is, the control box 3 defines a clearance 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 clearance 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 encroach upon the boundary area occupied by the control box 3 in the first direction F1. This results in the stacking length L of the fan assembly 12, the control box 3, and the fresh air component 2 along the first direction F1 being less than the sum of the lengths of each of the fan assembly 12, the control box 3, and the fresh air component 2 along the first direction F1. Therefore, the length of the air conditioner 100 along the first direction F1 can be reduced, facilitating a miniaturized design of the air conditioner 100 and making installation easier.

[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. 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 of the electrical control box 3 furthest from the fresh air component 2 in the first direction F1, and the second plane is the plane passing through the point of the electrical control box 3 furthest from the fan assembly 12 in the first direction F1, so that the entire box body 31 can be completely located between the first plane and the second plane. In other words, the first plane and the second plane are the two closest planes that can accommodate the box body 31 in the plane perpendicular to the first direction F1.

[0093] For example, the air conditioner 100 is a wall-mounted air conditioner. The front end of the housing 31 is open to form an opening, through which the low-voltage board 33 can be inserted into the housing 31 from the rear. The cover 32 is located on the front side of the housing 31 to enclose the circuit board within the low-voltage board 33. Furthermore, the portion of the drive motor 122 and / or the fresh air component 22 that is in contact with the electrical control box 3 is located behind the cover 32, that is, the cover 32 covers the front side of the portion of the drive motor 122 and / or the fresh air component 2 that is in contact with the electrical control box 3. It is worth noting that the portion of the drive motor 122 and / or the fresh air component 2 that is in contact with the electrical control box 3 may or may not include at least a portion of the housing 31 between it and the cover 32.

[0094] Therefore, while taking into account the need to avoid the drive motor 122 and / or the fresh air component 22, the cover 32 can be exposed to facilitate the opening of the cover 32 for inspection of the inside of the electrical control box 3.

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

[0096] like Figure 4 and Figure 6 As shown, the electrical control box 3 includes a high-voltage board 34 disposed in the first box section 31c. The high-voltage board 34 extends in the front-to-back direction in the length direction and faces the main body component 1 and the fresh air component 2 on both sides in the thickness direction, respectively. The low-voltage board 33 is disposed in the second box section 31d, and the thickness direction of the low-voltage board 33 is in the front-to-back direction. The part of the drive motor 122 and / or the fresh air component 2 that is in close contact with the box body 31 is located below the first box section 31c and behind the second box section 31d.

[0097] Therefore, through the above-mentioned settings, the space of the air conditioner 100 in the vertical and horizontal directions can be fully utilized, which helps to reduce the space occupied by the electrical control box 3 in the horizontal direction, reduces the overall size of the air conditioner 100, improves the space utilization rate of the air conditioner 100, and realizes the miniaturization design of the air conditioner 100.

[0098] Furthermore, through the above-mentioned arrangement, the electrical control box 3 can simultaneously accommodate both the high-voltage board 34 and the low-voltage board 33, and can avoid interference between the high-voltage board 34 and the low-voltage board 33, thereby improving the reliability of the electrical control box 3. Moreover, the front end of the box body 31 is open to form an opening, allowing both the high-voltage board 34 and the low-voltage board 33 to be inserted into the box body 31 from the rear through the opening. The box cover 32 is located on the front side of the box body 31 to enclose both the high-voltage board 34 and the low-voltage board 33 within the box body 31, improving assembly convenience.

[0099] For example, the first box portion 31c can be configured as a flat box with a height smaller than its length and width. The length direction of the first box portion 31c is the front-to-back direction, the width direction is the up-and-down direction, and the height direction is the left-to-right direction. The length, width, and thickness of the high-voltage board 34 are consistent with the length, width, and height of the first box portion 31c. Simultaneously, the second box portion 31d can be configured as a flat box with a height smaller than its length and width. The height direction of the second box portion 31d is the front-to-back direction, the width direction is the left-to-right direction, and the length direction is the up-and-down direction. The length, width, and thickness of the low-voltage board 33 are consistent with the length, width, and height of the second box portion 31d.

[0100] With the above arrangement, the clearance space 3a formed behind the second box 31d can be 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 clearance space 3a, which is conducive 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, such as Figure 4 As shown, a plurality of wire-clamping ports 31e are provided on the side wall of the first box 31c near the fan assembly 12. The plurality of wire-clamping ports 31e are spaced apart in the vertical direction. The air conditioner 100 includes an electric auxiliary heater. The fan wire 45 connected to the fan assembly 12 and the electric auxiliary heating wire 46 connected to the electric auxiliary heater extend into the first box 31c through different wire-clamping ports 31e to be connected to the power board 34 respectively.

[0102] For example, multiple wire-locking ports 31e are spaced apart vertically. The air conditioner 100 includes an electric auxiliary heater, which can be used to heat the air blown out by the fan assembly 12. The power lines include an electric auxiliary heating wire 46 and a fan wire 45. The electric auxiliary heater is connected to the electric auxiliary heating wire 46, and the fan assembly 12 is connected to the fan wire 45. The wire-locking ports 31e are located at the end of the housing 31 near the cover 32 and are open towards the cover 32. The fan wire 45 and the electric auxiliary heating wire 46 can be respectively locked into different wire-locking ports 31e from the open ends to pass through the wall of the first housing 31c, so that the fan wire 45 and the electric auxiliary heating wire 46 can extend into the first housing 31 to connect with the power board 34, thereby allowing the electrical control box 3 to supply power to the fan assembly 12 and the electric auxiliary heater through the power board 34. It is understandable that by setting the fan wire 45 and the electric auxiliary heating wire 46 to be connected to different wire clamps 31e, the risk of wire compression can be eliminated, the stability of the electrical control box 3 can be improved, and thus the reliability of the air conditioner 100 can be improved.

[0103] For example, the housing 31 includes a stop portion 35, which is disposed on the side of the first housing portion 31c near the fan assembly 12. At least a portion of the stop portion 35 is spaced apart from the first housing portion 31c to form a wire-receiving space 36 between the stop portion 35 and the first housing portion 31c. The wire-receiving space 36 can be used to accommodate a high-voltage wire passing through the wire-holding port 31e. It should be noted that the high-voltage wire includes a fan wire 45 and an auxiliary electric heating wire 46.

[0104] The air conditioner 100 includes a fan assembly 12 and a heat exchange assembly 11. The fresh air component 2 and the electrical control box 3 are both located on the left or right side of the heat exchange assembly 11. A refrigerant pipe is externally connected to the heat exchange assembly 11, located on the side of the heat exchange assembly 11 closest to the electrical control box 3. The heat exchange assembly 11 can exchange heat with the air conditioning air through the refrigerant pipe, enabling the air conditioning air to cool or heat the indoor space.

[0105] The stop part 35 can block the refrigerant pipe from the refrigerant pipe space 36. When condensation forms on the outer wall of the refrigerant pipe, the stop part 35 can prevent the condensation from flowing to the power line.

[0106] Understandably, the wire space 36 can be used to accommodate the excess part of the power wire to eliminate the error in the length of the power wire, ensuring the accurate installation of the power wire, and the stop part 35 can prevent condensate from flowing along the power wire and causing danger, thus improving the safety of the air conditioner 100.

[0107] In some embodiments of the present invention, such as Figure 4 As shown, there are two wire-locking ports 31e, located at the upper and lower ends of the first box wall 311 respectively, and both pass through in the left and right direction. The stop part 35 is constructed as an elastic buckle 35a. The two elastic buckles 35a are spaced apart in the vertical direction to form a wire-passing port 35b between the two elastic buckles 35a. The wire-passing port 35b is located between the two wire-locking ports 31e in the vertical direction. The fan wire 45 is adapted to enter the wire-holding space 36 through the wire-passing port 35b and pass upward into the upper wire-locking port 31e. The electric auxiliary heating wire 46 is adapted to enter the wire-holding space 36 through the wire-passing port 35b and pass downward into the lower wire-locking port 31e.

[0108] For example, refer to Figure 4 As shown, there can be two wire-locking ports 31e, which are respectively connected to the upper and lower ends of the first box wall 311, and both wire-locking ports 31e penetrate the side wall of the first box part 31c in the left-right direction. The stop part 35 includes two elastic buckles 35a, which are spaced apart in the vertical direction to form a wire passage 35b between the two elastic buckles 35a. The wire passage 35b is connected to the wire-receiving space 36, so that the fan wire 45 and the electric auxiliary heating wire 46 can enter the wire-receiving space 36 through the wire passage 35b. The wire-receiving space 36 is connected to the wire-locking ports 31e, and the fan wire 45 and the electric auxiliary heating wire 46 entering the wire-receiving space 36 can be respectively installed into the corresponding wire-locking ports 31e.

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

[0110] For example, the power cord 47 and the indoor / outdoor unit connection cable 48 are both passed through the cable hole 31f and electrically connected to the power board 34. The external power supply can supply power to the power board 34 through the power cord 47, and the power board 34 can supply power to the outdoor unit of the air conditioner through the indoor / outdoor unit connection cable 48.

[0111] For example, such as Figure 4 and Figure 6 As shown, in the specific installation process, first connect the power cord 47 and the indoor / outdoor unit connection cord 48 to the power board 34, and pull out the fan cord 45 and the electric auxiliary heating cord 46 to the front of the box 31; then, the power board 34 can be installed into the first box 31c from front to back; next, the power cord 47 and the indoor / outdoor unit connection cord 48 can be inserted into the wire hole 31f from the right side of the box 31; next, the fan cord 45 and the electric auxiliary heating cord 46 can be inserted into the wire storage space 36 through the wire passage 35b from the left side of the box 31 and connected to the power board 34; finally, the fan cord 45 can be pulled upward along the wire storage space 36 to pass through the upper wire hole 31e, and the electric auxiliary heating cord 46 can be pulled downward along the wire storage space 36 to pass through the lower wire hole 31e, thus realizing the wiring layout of the power board 34.

[0112] With the above settings, the fan wire 45 and the electric auxiliary heating wire 46 entering the wire space 36 can be kept parallel to the wire clamping port 31e, so that the fan wire 45 and the electric auxiliary heating wire 46 can be more easily clamped into the corresponding wire clamping port 31e, reducing the assembly difficulty of the air conditioner 100, and preventing the fan wire 45 and the electric auxiliary heating wire 46 from crossing over, thus improving the design rationality of the air conditioner 100.

[0113] In some embodiments of the present invention, such as Figure 5 As shown, the terminal block 331 includes a third terminal block 3314 located on the upper part of the low-voltage board 33, and the high-voltage board connecting line 49 connecting the high-voltage board 34 and the low-voltage board 33 is connected to the third terminal block 3314.

[0114] Therefore, the electrical connection between the high-voltage board 34 and the low-voltage board 33 can be achieved simply and effectively, thus realizing power supply.

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