[0021] In this embodiment, when the sealed cabin is subjected to an external force that separates it from the box body, the installation hem blocks the inlet plate from moving outward, thereby forming an effective blocking effect on the sealed cabin.

[0022] Optionally, the box body is provided with a mounting opening;

[0023] The side panel is provided with an installation folding edge, which is arranged against the line inlet board; the line inlet board is located outside the box, and its board surface away from the installation folding edge is arranged against the outer periphery of the installation opening.

[0024] In this embodiment, the shapes of the installation opening and the sealed cabin do not need to be specially adapted, and it is only necessary to ensure that the installation opening is completely enclosed by the cable entry plate.

[0025] Optionally, the mounting flange is perpendicular to the side panel and parallel to the cable entry panel.

[0026] In this embodiment, the bending rigidity of the side panels can be enhanced, making the entire sealed cabin more stable when subjected to external forces, and making the mounting flanges more tightly attached to the cable entry board, thereby reducing the presence of assembly gaps.

[0027] Optionally, there are one or more line inlets, and the same number of line outlets are arranged corresponding to the line inlets.

[0028] In this embodiment, it is beneficial to shorten the layout length of the wire harness and reduce the crossing and entanglement between the wire harnesses.

[0029] Optionally, the wire inlet is provided with a wire inlet seal, which is used to gather the wire harness and seal the wire inlet; and / or,

[0030] The wire outlet is provided with a wire outlet seal, which is used to gather the wire harness and seal the wire outlet.

[0031] In this embodiment, the incoming line seal, the sealing material and the outgoing line seal realize three-layer routing sealing, and under the action of the three-layer routing sealing, a better routing sealing effect is achieved.

[0032] Optionally, the sealing material includes rubber, putty, sealant or a sealing gasket.

[0033] In this embodiment, the sealing material includes but is not limited to rubber, putty, sealant or sealing gasket, as long as it can play a sealing and filling role.

[0034] In some embodiments, the air conditioner includes the electric control box.

[0035] In this embodiment, the electrical control box is applied to the air conditioner. Under the action of the three-layer wiring sealing, a better wiring sealing effect is achieved, effectively isolating moisture, dust or flying insects in the external environment from entering the interior of the box, thereby improving the safety and reliability of the electrical control box and the air conditioner.

[0053] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0055] Combine Figure 1-6 As shown, an embodiment of the present disclosure provides an air conditioner, comprising an electric control box. An electric control component 120 is arranged in the electric control box, and the electric control component 120 is connected to an external device through a wiring harness.

[0056] The embodiment of the present disclosure provides an electric control box, comprising a box body 100 and a sealed cabin 200. Figure 1 and Figure 2 As shown, the box 100 is used to house the electronic control component 120; the sealed cabin 200 is arranged against one side of the box 100, and its interior is filled with sealing material 240; the sealed cabin 200 is provided with a wire inlet 211 and a wire outlet 221, and the wire inlet 211 is connected to the interior of the box 100; wherein, the first end of the wiring harness is connected to the electronic control component 120, and the second end passes through the sealed cabin 200 from the wire inlet 211 and exits from the wire outlet 221.

[0057] In this embodiment, after the first end of the wiring harness is connected to the electronic control assembly 120, it is routed sequentially through the cable inlet 211 and cable outlet 221 of the sealed chamber 200, and then connected to external devices. Because the sealed chamber 200 is filled with sealing material 240, the wiring harness within the sealed chamber 200 is pressed and sealed by the sealing material 240, effectively protecting it. This reduces the exposed portion of the wiring harness outside the housing 100, effectively preventing damage or aging. Furthermore, it effectively prevents moisture, dust, flying insects, and other debris from the external environment from entering the housing 100 through the cable inlet 211.

[0058] Optionally, the sealing material 240 includes rubber, mastic, sealant or a sealing gasket.

[0059] In this embodiment, the sealing material 240 is a soft material to facilitate filling into the sealed chamber 200 and facilitate compaction with the wiring harness after filling. The sealing material 240 includes but is not limited to rubber, cement, sealant, or a gasket, as long as it can provide a sealing and filling function.

[0060] Alternatively, as Figure 3 and Figure 4 As shown, the sealed cabin 200 is composed of an inlet plate 210, an outlet plate 220 and multiple side plates 230, and the inlet plate 210 is arranged close to the box body 100, and the outlet plate 220 is arranged on the side of the inlet plate 210 away from the box body 100; wherein, the inlet port 211 is opened on the inlet plate 210, and the outlet port 221 is opened on the outlet plate 220.

[0061] In this embodiment, the sealed cabin 200 forms an enclosed space by combining an inlet plate 210, an outlet plate 220, and multiple side panels 230. During installation, the inlet plate 210 is positioned close to the housing 100, eliminating any gap between the sealed cabin 200 and the housing 100. This facilitates the wiring harness extending from the housing 100 to pass directly through the inlet port 211 and into the sealed cabin 200.

[0062] Exemplarily, the sealed cabin 200 is constructed in a rectangular parallelepiped shape, wherein the top surface of the rectangular parallelepiped serves as the inlet board 210 , the bottom surface of the rectangular parallelepiped serves as the outlet board 220 , and the four side surfaces of the rectangular parallelepiped serve as four side panels 230 .

[0063] In another exemplary embodiment, the sealed cabin 200 is constructed in a cylindrical shape (not shown), with the top surface of the cylinder serving as the inlet plate 210 , the bottom surface of the cylinder serving as the outlet plate 220 , and the curved side surfaces of the cylinder serving as the side plates 230 .

[0064] Optionally, there are one or more line inlets 211 , and the same number of line outlets 221 are arranged corresponding to the line inlets 211 .

[0065] In this embodiment, each wire inlet 211 is used to gather a wire harness, each of which includes one or more wires. A corresponding number of wire inlets 211 and wire outlets 221 are provided based on the wiring requirements of the electrical control box. Furthermore, the corresponding placement of the wire outlets 221 with the wire inlets 211 helps shorten the wiring length of the wire harnesses and reduce cross-wiring and entanglement between wire harnesses.

[0066] For example, the inlet board 210 has three inlets 211 arranged in a herringbone pattern. The outlet board 220 has three outlets 221, each corresponding to one of the inlets 211. After the three wire harnesses enter the sealed cabin 200 through the three inlets 211, they exit the sealed cabin 200 directly through the corresponding outlets 221 to connect to external devices.

[0067] Alternatively, as Figure 2 As shown, the box body 100 is provided with a mounting opening 110 ; the side panel 230 is provided with a mounting fold 231 , and the mounting fold 231 is disposed against the inner periphery of the mounting opening 110 .

[0068] In this embodiment, the mounting flange 231 is located inside the housing 100 and abuts against the inner periphery of the mounting opening 110. Thus, when the sealed capsule 200 is subjected to an external force that forces it to separate from the housing 100, the inner periphery of the mounting opening 110 blocks the mounting flange 231 from moving outward, thereby effectively blocking the sealed capsule 200.

[0069] For example, the mounting opening 110 is configured as a rectangular opening with four straight edges. The sealed cabin 200 is configured as a rectangular parallelepiped, with the four sides of the rectangular parallelepiped serving as four side panels 230. Each side panel 230 has a mounting flange 231, which corresponds to the four straight edges and all four mounting flanges 231 abut against the inner periphery of the mounting opening 110.

[0070] Optionally, the line inlet plate 210 is disposed in the box body 100 , and the periphery of the line inlet plate 210 is disposed in contact with the installation flange 231 .

[0071] In this embodiment, the cable entry plate 210 abuts against the mounting flange 231, which in turn abuts against the inner edge of the mounting opening 110. The area of ​​the cable entry plate 210 is slightly larger than that of the mounting opening 110. When the sealed cabin 200 is subjected to an external force that forces it to separate from the housing 100, the mounting flange 231 prevents the cable entry plate 210 from moving outward, thereby effectively blocking the sealed cabin 200.

[0072] Optionally, corresponding screw holes are provided on the periphery of the inlet plate 210, the mounting flange 231, and the box body 100. The inlet plate 210 and the mounting flange 231 can be fixed to the inner periphery of the mounting opening 110 using bolt fasteners.

[0073] For example, during assembly, the cover of the box body 100 is first opened, and then the sealed cabin 200 is extended from the installation opening 110 to the outside of the box body 100. After the outlet plate 220 and the side plate 230 pass through the installation opening 110, the side plate 230 is abutted against the inner wall of the installation opening 110, and the installation flange 231 is abutted against the inner peripheral edge of the installation opening 110. Then, the inlet plate 210 is covered on the inner side of the installation opening 110, and the peripheral edge of the inlet plate 210 is abutted against the installation flange 231. Finally, bolt fasteners are used to pass through the inlet plate 210, the installation flange 231 and the box body 100 in sequence to fix the sealed cabin 200 to the box body 100.

[0074] Optionally, the box body 100 is provided with an installation opening 110; the side panel 230 is provided with an installation fold 231, and the installation fold 231 is arranged in abutment with the incoming line board 210; the incoming line board 210 is located outside the box body 100 (not shown in the figure), and its plate surface away from the installation fold 231 is arranged in abutment with the outer periphery of the installation opening 110.

[0075] In this embodiment, the inlet plate 210 is located outside the housing 100 and has a first panel and a second panel facing each other. The mounting flange 231 abuts the first panel, while the second panel is located away from the mounting flange 231 and abuts the outer periphery of the mounting opening 110. Because the inlet plate 210 is located outside the mounting opening 110, the side panels 230 of the sealed cabin 200 do not contact the inner wall of the mounting opening 110. Therefore, the shapes of the mounting opening 110 and the sealed cabin 200 do not require special adaptation; it is sufficient to ensure that the mounting opening 110 is completely enclosed by the inlet plate 210.

[0076] Optionally, the mounting flange 231 is arranged perpendicular to the side panel 230 and parallel to the cable entry panel 210 .

[0077] In this embodiment, the design of the mounting flange 231 being perpendicular to the side panel 230 can enhance the bending rigidity of the side panel 230, making the entire sealed cabin 200 more stable when subjected to external forces. The design of the mounting flange 231 being parallel to the cable inlet plate 210 allows the mounting flange 231 to be more tightly attached to the cable inlet plate 210, reducing the presence of assembly gaps.

[0078] Alternatively, as Figure 3 and Figure 5 As shown, the wire inlet 211 is provided with a wire inlet seal 250 , which is used to gather the wire harness and seal the wire inlet 211 .

[0079] In this embodiment, the wire inlet seal 250 not only gathers the wire harness, but also provides a protective barrier for the wire harness, thereby reducing friction and wear between the wire harness and the edge of the wire inlet 211 and extending the service life of the wire harness.

[0080] For example, the wire inlet seal 250 is a wire-passing rubber ring with a slot around it and a valve structure in the middle thereof. During installation, the slot is clamped to the edge of the wire inlet 211 and the wire harness is passed through the valve structure.

[0081] Alternatively, as Figure 4 and Figure 5 As shown, the wire outlet 221 is provided with a wire outlet seal 260 , which is used to gather the wire harness and seal the wire outlet 221 .

[0082] In this embodiment, the wire outlet seal 260 gathers the wire harness and makes the wire harness more stable at the wire outlet 221, making it less likely to loosen or fall off due to vibration or external force, thereby ensuring the reliability of the wire harness connection.

[0083] Exemplarily, the outlet seal 260 utilizes a wire-passing seal buckle, which includes a fixed end and a branching end. The fixed end of the wire-passing seal buckle is mounted on the outlet 221, while the branching end is located outside the sealed compartment 200. Furthermore, the branching end is provided with one or more branching openings to facilitate the proper distribution of the wires extending from the sealed compartment 200 as needed.

[0084] In combination with the above embodiments, under the action of the sealed cabin 200, three-layer wiring sealing can be achieved, such as Figure 6 As shown. When arranging the wiring harness, the first end of the wiring harness is connected to the electronic control component 120, and the second end thereof passes through the incoming wire seal 250 to enter the sealed cabin 200. Here, the incoming wire seal 250 serves as the first layer of sealing structure. Then, the wiring harness located in the sealed cabin 200 is pressed tightly by the sealing material 240. Here, the sealing material 240 serves as the second layer of sealing structure. Finally, the second end of the wiring harness passes through the outgoing wire seal 260 and extends out of the sealed cabin 200, thereby being connected to the external device. Here, the outgoing wire seal 260 serves as the third layer of sealing structure. In this way, under the action of the three-layer wiring seal, a better wiring sealing effect is achieved, which effectively isolates moisture, dust or flying insects in the external environment from entering the interior of the box 100, thereby improving the safety and reliability of the electrical control box and the air conditioner.
