[0002] The interior of the duct air conditioner is equipped with multiple components such as the fan, evaporator, and electrical box. Multiple components are set in different positions and all need to be connected to the control motherboard with wires to achieve corresponding electrical control.

[0003] In the related technology, wires are usually restrained and fixed with wire ties or buckles according to the actual internal structure of the unit to prevent the wires from being damaged by the sharp edges of sheet metal parts, screw heads or rotating parts during the use of the unit. However, since the electrical box is close to the evaporator, the evaporator will lower the ambient temperature around it when it is working. Water vapor in the air is easy to precipitate and condense on the surface of the wires.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0054] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0055] In the prior art, wires are usually restrained and fixed with wire ties or buckles according to the actual internal structure of the unit to prevent the wires from being damaged by the sharp edges of sheet metal parts, screw heads or rotating parts during the use of the unit. However, since the electrical box is close to the evaporator, the evaporator will lower the ambient temperature around it when it is working, and the water vapor in the air will easily precipitate and condense on the surface of the wires. When the dew drops increase to a certain extent, condensed water will form and flow along the wires to the inside of the electrical box, causing a short circuit on the control mainboard and resulting in unit failure.

[0056] In order to solve the technical problem that condensed water in the existing air-conditioning indoor unit will flow along the wires to the inside of the electrical box, causing a short circuit in the control main board and leading to unit failure, the present application provides a wiring device, an air-conditioning indoor unit and an air conditioner, which can prevent condensed water from flowing into the inside of the electrical box and causing a short circuit in the control main board, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0057] like Figure 1 to Figure 2 As shown, the present application provides a wiring device 1, which is arranged on an air conditioner indoor unit 100. The air conditioner indoor unit 100 includes a unit body 2, an evaporator 3 and an electrical box 5. The evaporator 3 is arranged in the internal space of the unit body 2, and the electrical box 5 is arranged on the unit body 2. The wiring device 1 includes a shell 12 and a pipe 13; the shell 12 is arranged on the unit body 2, one end of the shell 12 passes through the unit body 2 and extends into the internal space of the unit body 2, and the shell 12 is provided with a first accommodating cavity 121 ( Figure 4As shown in the figure, the first accommodating chamber 121 is used for passing the power line 6; the pipe 13 is arranged on the shell 12, and the pipe 13 is inclined relative to the horizontal plane to have a high end and a low end. The high end of the pipe 13 is connected to the first accommodating chamber 121 to drain the condensed water caused by the evaporator 3 in the first accommodating chamber 121 from the high end to the low end.

[0058] When making electrical connections, the staff will insert the wire 6 located in the internal space of the unit body 2 into the pipe 13 from the lower end of the pipe 13, and then pass through the first accommodating cavity 121 of the shell 12 to connect with the electrical box 5. At this time, the wire 6 passes through the wiring device 1 from the front of the unit and enters the back of the unit. The pipe 13 and the shell 12 can effectively restrict the direction of the wire 6. At the same time, the shell 12 and the pipe 13 can protect the wire 6 to prevent the wire 6 from being damaged by the sharp edges of the sheet metal, screw heads or rotating moving parts during the use of the unit. During the operation of the unit, the evaporator 3 causes the ambient temperature in the first accommodating chamber 121 to be low, so that condensed water condenses on the outer surfaces of the shell 12 and the pipe 13 due to the low ambient temperature. The condensed water flows from top to bottom along the outer surface of the shell 12 under the action of its own gravity. Since the pipe 13 is inclined relative to the horizontal plane, the condensed water is drained from the high end of the pipe 13 to the low end of the pipe 13. The dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit on the control main board, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0059] It should be noted that the electrical box 5 can be set at any position of the unit body 2 according to the actual layout requirements of the unit. For example, the electrical box 5 can be set above the unit body 2, that is, the electrical box 5 is located above the evaporator 3. At this time, the condensed water caused by the evaporator 3 will not flow into the interior of the electrical box 5 along the wire 6 under the action of gravity. The first end of the wire 6 is connected to the electrical box 5, and the second end of the wire 6 is connected to the electrical device in the internal space of the unit body 2. Since the pipeline 13 is inclined relative to the horizontal plane to have a high end and a low end, the condensed water is drained from the high end of the pipeline 13 to the low end of the pipeline 13, and the condensed water drips from the low end of the pipeline 13 onto the unit body 2. Therefore, the condensed water will not flow into the electrical device in the internal space of the unit body 2 along the wire 6; or, the electrical box 5 can be set below the unit body 2, that is, the electrical box 5 is located below the evaporator 3; or, the electrical box 5 is set on the outer surface of the unit body 2; or, the electrical box 5 is set on the inner surface of the unit body 2, and the present application does not make specific restrictions on this.

[0060] In one embodiment, the electrical box 5 is disposed on the outer surface of the unit body 2, and the electrical box 5 is located below the evaporator 3. It should be noted that the electrical box 5 can be a rectangular parallelepiped structure as a whole, and the electrical box 5 is fixedly installed on the outer surface of the unit body 2. After the unit is installed, for example, Figure 2As shown, the evaporator 3 is located above the electrical box 5, and the electrical box 5 is arranged below the unit body 2 (which is the lowest position of the unit). It is understandable that when making electrical connections, the staff will insert the wire 6 located in the internal space of the unit body 2 into the pipe 13 from the lower end of the pipe 13, and then connect it to the electrical box 5 after passing through the first accommodating chamber 121 of the shell 12. The condensed water flows from top to bottom along the outer surface of the shell 12 under the action of its own gravity. Since the pipe 13 is inclined relative to the horizontal plane, the condensed water is drained from the high end of the pipe 13 to the low end of the pipe 13. The dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit on the control main board, thereby ensuring the electrical safety of the unit.

[0061] Furthermore, if Figure 3 As shown, the pipe 13 has a first opening 1311 and a second opening 1331 arranged opposite to each other. The first opening 1311 of the pipe 13 is lower than the second opening 1331 of the pipe 13 on a horizontal plane. The second opening 1331 of the pipe 13 is connected to the first accommodating chamber 121 of the shell 12 .

[0062] The electric wire 6 passes through the first opening 1311 of the pipe 13 and the second opening 1331 of the pipe 13, and is connected to the electrical box 5 after passing through the first accommodating chamber 121 of the shell 12, thereby effectively restricting the direction of the electric wire 6. At the same time, the shell 12 and the pipe 13 can protect the electric wire 6 and prevent the electric wire 6 from being damaged by the sharp edge of the sheet metal, the screw head or the rotating moving parts during the use of the unit. Since the second opening 1331 of the pipe 13 is higher than the first opening 1311 of the pipe 13, even if condensed water condenses on the outer surface of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under the action of its own gravity, or flows from the second opening 1331 of the pipe 13 to the first opening 1311 of the pipe 13, and the dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit of the control mainboard, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0063] The shell 12 and the pipe 13 can be made of hard materials, soft materials, or different materials can be used for the shell 12 and the pipe 13. In a preferred example, the shell 12 and the pipe 13 are integrally formed to reduce production processes and reduce the difficulty of subsequent operation.

[0064] The shell 12 is protruding toward one end extending into the unit body 2. On the one hand, it is convenient for threading the wires 6, and on the other hand, it can reserve sufficient space for the pipe 13, thereby increasing the height of the second opening 1331 of the pipe 13, so that condensed water can flow from the high end (second opening 1331) of the pipe 13 to the low end (first opening 1311).

[0065] Optionally, as shown in Figure 1, the unit body 2 includes multiple shells, which are connected one by one to form a box with an internal space, and two adjacent shells can be fastened with bolts. The unit body 2 can also be provided with a lifting ear 23 to install the air conditioner indoor unit 100 indoors.

[0066] In some embodiments, Figure 4 As shown, the pipeline 13 includes a first horizontal section 131, a curved section 132 and a second horizontal section 133, the first horizontal section 131, the curved section 132 and the second horizontal section 133 are connected in sequence, the end of the second horizontal section 133 away from the curved section 132 is connected to the shell 12, the first horizontal section 131 and the second horizontal section 133 can be parallel to the horizontal plane, and the curved section 132 is inclined relative to the horizontal plane; the first opening 1311 of the pipeline 13 is arranged at the end of the first horizontal section 131 away from the curved section 132, and the second opening 1331 of the pipeline 13 is arranged at the end of the second horizontal section 133 away from the curved section 132.

[0067] The curved section 132 is tilted relative to the horizontal plane, so that the second opening 1331 of the pipe 13 is higher than the first opening 1311 of the pipe 13. Even if condensed water condenses on the outer surface of the housing 12 and the pipe 13 due to the low ambient temperature, the condensed water flows down along the curved section 132 under the action of its own gravity, that is, from the second opening 1331 of the pipe 13 to the first opening 1311 of the pipe 13. The dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit of the control mainboard, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit. By setting the first horizontal section 131 and the second horizontal section 133, the direction of the wire 6 can be relatively gentle, avoiding the wire 6 from being damaged by friction with the inner wall of the pipe 13 due to excessive bending, thereby further ensuring electrical safety and improving the working reliability of the unit.

[0068] Of course, multiple curved sections 132 can be provided, and the slopes of the multiple curved sections 132 can be set to be the same or different. The slopes of the multiple curved sections 132 can gradually decrease from the direction away from the first opening 1311, or can gradually increase. Of course, they can also be set to be the same, and can be adjusted specifically according to the internal space and routing requirements of the unit body 2.

[0069] In one example, the slope of the curved section 132 gradually increases and then gradually decreases in a direction approaching the second opening 1331 .

[0070] The slope of the curved section 132 gradually increases and then gradually decreases in the direction approaching the second opening 1331, so that the connecting section between the curved section 132 and the first horizontal section 131 and the connecting section between the curved section 132 and the second horizontal section 133 transition slowly, avoiding excessive bending and wear of the electric wire 6 of the curved section 132, thereby ensuring the electrical safety of the unit.

[0071] Since the unit body 2 and the electrical box 5 need to be fixed with bolts or the like, it is inevitable to drill holes in the unit body 2. Condensed water may penetrate through the connecting holes between the unit body 2 and the electrical box 5 and enter the interior of the electrical box 5, causing a short circuit in the control main board in the electrical box 5, resulting in unit failure.

[0072] In some embodiments, Figure 5 As shown, it includes a water receiving tray 14 , which is arranged between the pipeline 13 and the unit body 2 .

[0073] After the unit is installed, Figure 5 As shown, the evaporator 3 is located above the electrical box 5, and the electrical box 5 is located below the unit body 2 (which is the lowest position of the unit). When making electrical connections, the staff inserts the wire 6 into the pipe 13 from the lower end of the pipe 13, and connects it to the electrical box 5 after passing through the first accommodating chamber 121 of the shell 12. At this time, the wire 6 passes through the wiring device 1 from the front of the unit and enters the back of the unit. The pipe 13 and the shell 12 can effectively restrict the direction of the wire 6. At the same time, the shell 12 and the pipe 13 can protect the wire 6 to prevent the wire 6 from being damaged by the sharp edge of the sheet metal, the screw head or the rotating moving parts during the use of the unit. Since the pipe 13 is arranged at an angle, even if condensed water condenses on the outer surfaces of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under the action of its own gravity, or flows from the high end of the pipe 13 to the low end of the pipe 13. The dripping condensed water is first isolated by the water receiving tray 14, and the condensed water falls into the water receiving tray 14 from the low end of the pipe 13, which can prevent the condensed water from entering the electrical box 5 from the connecting hole between the unit body 2 and the electrical box 5 and causing a short circuit on the control main board, thereby ensuring the electrical safety of the unit and further improving the working reliability of the unit.

[0074] The condensed water received by the water receiving tray 14 will be drained away through a drain pipe or pumped away by a water pump, and will not overflow to affect the performance of the electrical box 5 .

[0075] Of course, this embodiment can also be combined with the above-mentioned embodiments to obtain more embodiments. In one example, the pipe 13 has a first opening 1311 and a second opening 1331 that are relatively arranged. The first opening 1311 of the pipe 13 is lower than the second opening 1331 of the pipe 13 on the horizontal plane. The second opening 1331 of the pipe 13 is connected to the first accommodating chamber 121 of the shell 12, and the water receiving tray 14 is arranged below the second opening 1331 of the pipe 13 to receive condensed water. Since the second opening 1331 of the pipe 13 is higher than the first opening 1311 of the pipe 13, even if condensed water condenses on the outer surface of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under its own gravity, or flows from the second opening 1331 of the pipe 13 to the first opening 1311 of the pipe 13, and the dripping condensed water falls into the water receiving tray 14, which can prevent the condensed water from entering the inside of the electrical box 5 from the connection hole between the unit body 2 and the electrical box 5 and causing a short circuit of the control main board, thereby ensuring the electrical safety of the unit and further improving the working reliability of the unit. In one example, the pipe 13 includes a first horizontal section 131, a curved section 132 and a second horizontal section 133, the first horizontal section 131, the curved section 132 and the second horizontal section 133 are connected in sequence, and the water receiving tray 14 is arranged below the second horizontal section of the pipe 13 to receive the condensed water. Under the action of its own gravity, the condensed water flows from the first horizontal section 131 through the curved section 132, and then flows along the curved section 132 through the second horizontal section 133. Finally, the condensed water dripping from the second opening 1331 of the second horizontal section 133 falls into the water receiving tray 14, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit on the control main board, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0076] Furthermore, if Figure 5 As shown, the water receiving tray 14 includes a bottom plate 141 and a baffle 142 which are integrally arranged, and the baffle 142 is arranged around the edge of the bottom plate 141 .

[0077] In one example, the water receiving tray 14 can be an integrally formed sheet metal part. Specifically, a stamping process can be used to bend the edge of the bottom plate 141 toward one side of the pipe 13 to form a flange, and the flange is the baffle 142. Alternatively, in one example, the water receiving tray 14 is an integrally formed injection molded part, and the bottom plate and the baffle 142 are manufactured by an injection molding process. The baffle 142 can prevent excessive condensed water from flowing out of the water receiving tray 14, thereby improving the receiving capacity of the water receiving tray 14.

[0078] In some embodiments, Figure 5As shown, a convex frame 143 is provided on the side of the water receiving tray 14 facing away from the electrical box 5, and the convex frame 143 is arranged around the peripheral side of the housing 12. Specifically, the convex frame 143 is tightly in contact with the peripheral side of the housing 12, which plays a positioning role when installing the housing 12 and passing the wires 6, and can also prevent the condensed water on the outer surface of the housing 12 from flowing into the interior of the electrical box 5 along the gap between the housing 12 and the convex frame 143, further ensuring the electrical safety of the unit.

[0079] In some embodiments, Figure 6 and Figure 7 As shown, a third opening 122 for the power supply line 6 to pass through is provided at one end of the shell 12 facing the electrical box 5, and a cover plate 15 is provided on the shell 12. The end of the cover plate 15 close to the third opening 122 can be rotated relative to the shell 12 so that the cover plate 15 has a first state of being open relative to the third opening 122 and a second state of being covered relative to the third opening 122.

[0080] The wire 6 enters the pipe 13 from the first opening 1311 of the pipe 13, passes through the first accommodating cavity 121 of the housing 12 through the second opening 1331, and finally extends out from the third opening 122 of the housing 12 and is connected to the control mainboard in the electrical box 5. Figure 6 As shown, one end of the cover plate 15 close to the third opening 122 can rotate around the R axis. In the first state, the cover plate 15 is opened relative to the third opening 122, which is convenient for the staff to pass the wire 6; Figure 7 As shown, in the second state, the cover 15 is closed relative to the third opening 122, and the cover 15 is used to protect the wires 6 in the housing 12 from being exposed to the fan 4 ( Figure 2 (shown in the figure) on one side and is hit by the rotating blades in the volute 41. When installing the air conditioner indoor unit 100, first open the cover 15, thread the wire 6, and connect the wire 6 to the control main board in the electrical box 5, and then close the cover 15. During the operation of the unit, even if condensed water condenses on the outer surfaces of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under the action of its own gravity, or flows from the high end of the pipe 13 to the low end of the pipe 13. The dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit in the control main board, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit. Therefore, compared with the prior art, the present embodiment can, on the one hand, protect the wire 6 during the installation and use of the unit, preventing it from being exposed to one side of the fan 4 and being damaged by the rotating blades in the volute 41, or being damaged by hitting the sharp edges of sheet metal parts, screw heads or rotating moving parts, etc., and can also prevent condensation water from flowing into the electrical box 5 and causing a short circuit in the control main board, thereby ensuring the electrical safety of the unit.

[0081] Furthermore, the cover plate 15 includes a first plate 151 and a second plate 152 connected to each other. One end of the first plate 151 is connected to the shell 12, and the second plate 152 is connected to an end of the first plate 151 away from the shell 12. The first plate 151 and the second plate 152 are respectively detachably connected to the shell 12.

[0082] There is an angle between the first plate 151 and the second plate 152. The angle between the first plate 151 and the second plate 152 can be set to 80°, 85°, 90°, 95°, 100°, etc. For ease of manufacture and use, in a preferred embodiment, the angle between the first plate 151 and the second plate 152 is set to 90°. In the second state, the first plate 151 is connected to the housing 12, and the second plate 152 is connected to the housing 12, so that the cover plate 15 can be stably fixed on the housing 12, and the cover plate 15 can protect the wires 6 in the housing 12. In the first state, the first plate 151 is separated from the housing 12, and the second plate 152 is separated from the housing 12, so that the staff can pass the wires 6. Of course, the first plate 151, the second plate 152 and the shell 12 together constitute a first accommodating chamber 121, which can protect the wires 6 in the shell 12 and prevent them from being exposed to one side of the fan 4 and being damaged by the rotating blades in the volute 41. It can also prevent the wires 6 from being damaged by the sharp edges of sheet metal, screw heads or rotating moving parts during installation and use.

[0083] Furthermore, if Figure 6 As shown, an extension plate 123 is provided on the shell 12, a connecting plate 153 is provided on the side of the first flat plate 151 facing the first accommodating cavity 121, a first clip 154 ​​is provided on the connecting plate 153, and a first card slot 124 that is clipped and adapted to the first clip 154 ​​is provided on the shell 12; in the second state, the first clip 154 ​​is clip-connected with the first card slot 124, and the first flat plate 151 abuts against the extension plate 123.

[0084] In the second state, the first buckle 154 is connected with the first slot 124, so that the cover plate 15 is tightly connected with the extension plate 123 and is not easy to loosen. In the process of threading the wires, it is inevitable to disassemble the cover plate 15, so the first buckle 154 needs to bear a certain external force. The connecting plate 153 can enhance the structural strength of the first buckle 154 to avoid the first buckle 154 from cracking due to excessive force during the disassembly and assembly of the cover plate 15 and the shell 12. If the unit has a circuit fault or an electrical box control fault during use, it is necessary to check whether the surface of the wire 6 in the shell 12 is damaged or the connection is normal. When it is necessary to check the connection state or surface state of the wire 6 in the shell 12, an external force can be applied to the first buckle 154 to disengage the first buckle 154 from the first slot 124, and the end of the cover plate 15 close to the third opening 122 is rotated around the R axis to open the cover plate 15.

[0085] In one example, if Figure 6 As shown, the state in which the cover plate 15 and the extension plate 123 are tightly connected specifically means that the first flat plate 151 has a first plane A1 on the side facing the first accommodating cavity 121, and the extension plate 123 has a second plane A2 on the side facing the cover plate 15, and the first plane A1 is in contact with the second plane A2.

[0086] The first card slot 124 can be set to a square, trapezoid, circular, triangular, etc. shape, and the cross-sectional shape of the first buckle 154 corresponds to the first card slot 124 being set to a square, trapezoid, circular, triangular, etc. shape. In one example, the first card slot 124 can be set to a square, and the cross-sectional shape of the first buckle 154 is set to a square accordingly, and the length direction of the first card slot 124 is parallel to the horizontal direction.

[0087] There may be multiple first clips 154, and the first slots 124 may correspond one to another. For example, in one example, there are four first clips 154, and two first slots 124 are arranged on two opposite sides of the shell 12 to improve the connection stability between the shell 12 and the cover plate 15.

[0088] Furthermore, a second clip 155 is provided on the side of the second plate 152 facing the first accommodating cavity 121, and a second slot 125 that is snap-fitted with the second clip 155 is provided on the shell 12; in the second state, the second clip 155 is snap-fitted with the second slot 125, and the gap between the second plate 152 and the shell 12 forms a third opening 122.

[0089] In the second state, the second buckle 155 is engaged with the second slot 125, so that the cover 15 is tightly connected to the housing 12 and is not easy to be loosened. When it is necessary to check the state of the wire 6 in the housing 12, an external force can be applied to the second buckle 155 to disengage the second buckle 155 from the first slot 124, and the end of the cover 15 close to the third opening 122 is rotated around the R axis, so as to open the cover 15.

[0090] In one example, if Figure 6 As shown, the state in which the cover plate 15 is tightly connected to the shell 12 specifically means that the second flat plate 152 has a third plane B1 on the side away from the first accommodating cavity 121, and the shell 12 has a fourth plane B2, and the third plane B1 is flush with the fourth plane B2 and the two are in contact with each other.

[0091] The second slot 125 can be set to a square, trapezoid, circular, triangular, etc. shape, and the cross-sectional shape of the second buckle 155 corresponds to the second slot 125 being set to a square, trapezoid, circular, triangular, etc. shape. In one example, the second slot 125 can be set to a square, and the cross-sectional shape of the second buckle 155 is set to a square correspondingly, and the length direction of the second slot 125 is parallel to the vertical direction.

[0092] There may be multiple second clips 155, and there may be multiple second slots 125 corresponding to the first clips 154. For example, in one example, there are two second clips 155, and a second slot 125 is arranged on both sides of the shell 12 to improve the connection stability between the shell 12 and the cover plate 15.

[0093] In some embodiments, the extension plate 123 has a through hole 1231 , and a first fastener 156 is disposed on the through hole 1231 . The cover plate 15 can be fixed to the unit body 2 or other components through the first fastener 156 .

[0094] Specifically, Figure 7 As shown, in the second state, the through hole 1231 is disposed at the protruding portion of the extension plate 123 relative to the cover plate 15 .

[0095] In one example, if Figure 8 As shown, the partition 11 is arranged on the unit body 2, and the partition 11 and the unit body 2 can be arranged to be perpendicular to each other. The first fastener 156 can be a fastener such as a screw or a nut to clamp the shell 12 on the unit body 2. The partition 11 is provided with connecting holes corresponding to the through holes 1231 one by one. One end of the first fastener 156 passes through the through hole 1231 of the extension plate 123 and the connecting hole of the partition 11 in sequence. The extension plate 123 is fixedly connected to the partition 11 by the first fastener 156, so that the shell 12 can be fixed, so that the shell 12 is arranged on the unit body 2 through the partition 11.

[0096] Of course, in order to ensure the connection reliability of the shell 12 , a plurality of through holes 1231 may be provided. In one example, two through holes 1231 are provided, and the two through holes 1231 are symmetrically arranged on both sides of the cover plate 15 .

[0097] In the prior art, the common wiring method is to open a wire hole on the unit body 2, and then use a wire tie or buckle to fix the wire 6 after the wire passes through the wire hole. Since the opening cannot be effectively sealed, the air will form high-pressure air after passing through the fan 4. The high-pressure air will leak at the opening, affecting the efficiency of heat exchange between the high-pressure air and the evaporator 3, resulting in the refrigeration performance of the unit being affected. In order to prevent the high-pressure air from leaking from the second opening 1331 of the pipe 13, the present application also provides a first fastener at the second opening 1331 of the pipe 13, and the specific design is described as follows.

[0098] In some embodiments, Figure 2 and Figure 3 As shown, the indoor unit of the air conditioner includes a fan 4, and the wiring device 1 also includes a partition 11, which is arranged on the unit body 2. The partition 11 divides the internal space of the unit body 2 into a second accommodating chamber 21 and a third accommodating chamber 22. The second accommodating chamber 21 is used to accommodate the evaporator 3, and the third accommodating chamber 22 is used to accommodate the fan 4. The shell 12 and the pipeline 13 are both arranged in the second accommodating chamber 21.

[0099] It should be emphasized that the function of the partition 11 is to separate the fan 4 and the evaporator 3. After the air passes through the fan 4, high-pressure air will be formed. When the high-pressure air passes through the third accommodating chamber 22, heat exchange occurs with the evaporator 3 at the partition 11 and the unit body 2, thereby reducing the air temperature.

[0100] The pipe 13 is made of a soft material, and the second opening 1331 of the pipe 13 is provided with a second fastener 135 to seal the second opening 1331 of the pipe 13. The second fastener 135 can be a wire tie, which is used to tie the second opening 1331 of the pipe 13 to seal it, thereby preventing high-pressure air from leaking at the second opening 1331, thereby improving the heat exchange efficiency between the high-pressure air and the evaporator 3 and ensuring the refrigeration performance of the unit.

[0101] Of course, this embodiment can also be combined with the above-mentioned embodiments to obtain more embodiments. In one example, the pipe 13 has a first opening 1311 and a second opening 1331 that are relatively arranged. The first opening 1311 of the pipe 13 is lower than the second opening 1331 of the pipe 13 on the horizontal plane. The second opening 1331 of the pipe 13 is connected to the first accommodating chamber 121 of the shell 12, and the water receiving tray 14 is arranged below the second opening 1331 of the pipe 13 to receive condensed water. Since the second opening 1331 of the pipe 13 is higher than the first opening 1311 of the pipe 13, even if condensed water condenses on the outer surface of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under its own gravity, or flows from the second opening 1331 of the pipe 13 to the first opening 1311 of the pipe 13, and the dripping condensed water falls into the water receiving tray 14, which can prevent the condensed water from entering the inside of the electrical box 5 from the connection hole between the unit body 2 and the electrical box 5 and causing a short circuit of the control main board, thereby ensuring the electrical safety of the unit and further improving the working reliability of the unit. In one example, the pipe 13 includes a first horizontal section 131, a curved section 132 and a second horizontal section 133, the first horizontal section 131, the curved section 132 and the second horizontal section 133 are connected in sequence, and the water receiving tray 14 is arranged below the second horizontal section of the pipe 13 to receive the condensed water. Under the action of its own gravity, the condensed water flows from the first horizontal section 131 through the curved section 132, and then flows along the curved section 132 through the second horizontal section 133. Finally, the condensed water dripping from the second opening 1331 of the second horizontal section 133 falls into the water receiving tray 14, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit on the control main board, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0102] Therefore, compared with the existing method of fixing the wires 6 by wire ties or clips after the wires pass through the wire holes, the embodiment of the present application can not only improve the heat exchange efficiency between the high-pressure air and the evaporator 3, thereby ensuring the refrigeration performance of the unit; it can also prevent condensed water from entering the control main board in the electrical box 5, thereby ensuring the working reliability of the unit.

[0103] Furthermore, if Figure 4 As shown, a sealing ring 134 is disposed at the first opening 1311 of the pipe 13 . The sealing ring 134 is sleeved on the outer peripheral side of the pipe 13 , and the outer peripheral side of the sealing ring 134 is connected to the housing 12 .

[0104] By providing the sealing ring 134, on the one hand, it can prevent condensed water from leaking from the gap between the pipe 13 and the shell 12 and flowing into the interior of the electrical box 5, and on the other hand, it can improve the sealing between the pipe 13 and the shell 12 to prevent leakage of the high-pressure space and affect the heat exchange efficiency.

[0105] In some embodiments, Fig. 9As shown, the fan 4 includes two volutes 41 , which are arranged side by side in the horizontal direction, and the housing 12 is arranged between the two volutes 41 .

[0106] Providing two volutes 41 and corresponding rotating blades can improve the operating efficiency of the fan 4, thereby improving the heat exchange efficiency between the high-pressure air and the evaporator 3; arranging the housing 12 between the two volutes 41 can reduce the probability of the wire 6 being damaged by the rotating blades in the volute 41.

[0107] Of course, this embodiment can also be combined with the above-mentioned embodiments to obtain more embodiments. In one example, the shell 12 is provided with a third opening 122 for the power supply line 6 to pass through at one end thereof facing the electrical box 5. The shell 12 is provided with a cover plate 15. The end of the cover plate 15 close to the third opening 122 can rotate relative to the shell 12, so that the cover plate 15 has a first state of being open relative to the third opening 122 and a second state of being covered relative to the third opening 122. The wire 6 enters the pipe 13 from the first opening 1311 of the pipe 13, passes through the first accommodating cavity 121 of the shell 12 through the second opening 1331, and finally extends from the third opening 122 of the shell 12 and is connected to the control mainboard in the electrical box 5, as shown in FIG. Fig. 9 As shown. In the second state, the cover 15 is closed relative to the third opening 122, and the cover 15 is used to protect the wires 6 in the shell 12 to prevent them from being exposed to one side of the fan 4 and being damaged by the rotating blades in the volute 41. When installing the air conditioner indoor unit 100, first open the cover 15, thread the wires 6, and connect the wires 6 to the control mainboard in the electrical box 5, and then close the cover 15. During the operation of the unit, even if condensed water condenses on the outer surfaces of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under its own gravity, or flows from the high end of the pipe 13 to the low end of the pipe 13. The dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit of the control mainboard, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0108] like Figure 1 As shown, the present application also provides an air-conditioning indoor unit 100, including a unit body 2, an evaporator 3, an electrical box 5 and the wiring device 1 as described above, the evaporator 3 is arranged in the internal space of the unit body 2, the electrical box 5 is arranged on the outer surface of the unit body 2, and the partition 11 of the wiring device 1 is arranged on the unit body 2.

[0109] After the unit is installed, the evaporator 3 is located above the electrical box 5, and the electrical box 5 is located below the unit body 2 (which is the lowest position of the unit). The wire 6 enters the pipe 13 from the lower end of the pipe 13, and is connected to the electrical box 5 after passing through the first accommodating chamber 121 of the shell 12, thereby effectively restricting the direction of the wire 6. At the same time, the shell 12 and the pipe 13 can protect the wire 6 and prevent the wire 6 from being damaged by the sharp edges of the sheet metal, screw heads or rotating moving parts during the use of the unit. Since the pipe 13 is tilted, even if condensed water condenses on the outer surface of the shell 12 and the pipe 13 due to the low ambient temperature, the condensed water flows from top to bottom along the outer surface of the shell 12 under its own gravity, or flows from the high end of the pipe 13 to the low end of the pipe 13. The dripping condensed water is isolated by the unit body 2, which can prevent the condensed water from flowing into the electrical box 5 and causing a short circuit of the control main board, thereby ensuring the electrical safety of the unit and improving the working reliability of the unit.

[0110] The air conditioner indoor unit 100 also includes a fan 4, which is arranged in the internal space of the unit body 2. After the air passes through the fan 4, high-pressure air is formed. When the high-pressure air passes through the evaporator 3, heat exchange occurs with the evaporator 3, thereby reducing the air temperature. The cooled air forms cold air and is sent into the room, thereby achieving indoor cooling.

[0111] The present application also provides an air conditioner, comprising the air conditioner indoor unit 100 as described above.

[0112] The air conditioner also includes a compressor and a condenser. The compressor, condenser and evaporator 3 are connected by pipelines. Refrigerant flows in the pipelines. Refrigerant circulation can be achieved by the work of the compressor. The specific structure and working principle can refer to the existing technology and will not be described here.
