[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0034] like Figure 4 and Fig.14 As shown, the embodiment of the present application provides an electric control box 3, which is provided with a wiring hole 31, and the wiring hole 31 is configured to allow external wires to extend into the electric control box 3. The bottom wall of the wiring hole 31 is provided with a guide slope 321, and the guide slope 321 extends downward in a direction pointing to the outside of the electric control box 3.

[0035] In this way, the dew on the external wire body 9 can flow downward and outward along the guide slope 321 under the action of gravity, but cannot enter the electric control box 3 against gravity, thereby protecting the components in the electric control box 3 and improving the waterproofness of the electric control box 3.

[0036] In some embodiments, a wire clamp 34 is provided in the electric control box 3. Figure 2 , Figure 5 and Fig.11 As shown, the position of the wire clamp 34 is higher than the guide slope 321. The wire clamp 34 is configured to press the wire body passing through the wire routing hole 31 so that the wire body forms a water return bend 91 above the guide slope 321 in the wire passing hole 21. Fig.10 and Fig.11 shown.

[0037] In this way, the dew on the external wire body 9 can accumulate and gather along the external wire body 9 to the return water bend 91 under the action of gravity, and finally drip onto the guide slope 321, and then be discharged to the outside of the electric control box 3 along the guide slope 321, thereby better protecting the components in the electric control box 3 and improving the waterproofness of the electric control box 3.

[0038] The specific structure of the wire pressing clamp 34 is not limited, as long as it can press the wire body to ensure that the wire body forms a water return bend 91 above the guide slope 321 in the wiring hole 31.

[0039] In some exemplary embodiments, the electric control box 3 includes a box cover 32 and a box body 33. Figure 4 and Fig.12 As shown, the box cover 32 is located at the lower side of the box body 33 and is connected to the box body 33 in a covering manner.

[0040] The box body 33 is provided with a notch 331. Fig.13 As shown, a sealing gasket 332 is provided at the notch 331. Figure 4 and Figure 6 As shown, the sealing pad 332 is provided with a wire-passing slit 3320 for the wire body to pass through. In this way, after the wire body passes through the wire-passing slit 3320, the wire-passing slit 3320 can be filled to achieve preliminary sealing, which is conducive to preventing water vapor from entering the electric control box 3 through the wire slit 3320.

[0041] The material of the sealing gasket 332 may be, but is not limited to, rubber, silicone, etc. The fixing method of the sealing gasket 332 is not limited. For example, one of the outer wall of the sealing gasket 332 and the box body 33 may be provided with a sealing groove, and the other may be provided with a sealing rib, which may be embedded in the sealing groove, so that the sealing gasket 332 may be fixed at the notch 331 by an interference fit. Alternatively, a limiting groove communicating with the notch 331 may be provided in the box body 33, and a part of the sealing gasket 332 may be limited in the limiting groove.

[0042] like Figure 4 As shown, the number of notches 331 can be multiple, and the number of sealing pads 332 can also be multiple, which can be determined according to the wiring requirements. In one example, notches 331 and sealing pads 332 are provided on multiple side walls of the box body 33, and multiple notches 331 and sealing pads 332 are provided on the side wall facing the wiring member 4. Figure 4 As shown, it is convenient to connect the wires in the wiring groove 41 with the electric control box 3 .

[0043] In some embodiments, the lower end of the notch 331 is open. Fig.13 As shown, the wire-passing slit 3320 includes a first slit 3321 and at least one second slit 3322, the first slit 3321 passes through the lower end of the sealing pad 332, and the second slit 3322 intersects with the first slit 3321. In this way, the wire body can be pressed into the second slit 3322 through the lower end of the first slit 3321 (in the assembly process before leaving the factory, it can be directly pressed downward into the wire-passing slit 3320), and the installation is simple and quick.

[0044] In some embodiments, the box cover 32 and the box body 33 surround the wiring hole 31. Figure 4 The flow guiding slope 321 is disposed on the box cover 32 .

[0045] In some exemplary embodiments, the box cover 32 is provided with a sealing fold 323, such as Figure 4 As shown, the sealing fold 323 is pressed on the lower part of the sealing pad 332, and can press and fix the wire body passing through the wire slit 3320. In this way, the sealing fold 323 of the box cover 32 can be used to press the wire body to form a secondary seal, which is conducive to preventing water vapor from entering the electric control box 3 through the wire slit 3320.

[0046] In some exemplary embodiments, one end of the box body 33 and one end of the box cover 32 are provided with an anti-dropping slot 322 (such as Figure 7 and Fig.12 ), and the other has an anti-slip fold 334 (as shown Figure 4 , Figure 5 The other end of the box body 33 is provided with an anti-drop buckle 333, as shown. Figure 6 shown.

[0047] The anti-dropout slot 322 is inserted and limitedly matched with the anti-dropout folding edge 334 and the other end of the box cover 32 is embedded in the anti-dropout buckle 333, so that the box body 33 and the box cover 32 are pre-positioned.

[0048] In this way, during the assembly of the box body 33 and the box cover 32, the box body 33 and the box cover 32 can be pre-positioned first, freeing both hands, and then the box cover 32 and the box body 33 are fixedly connected by fasteners such as screws. Accordingly, screw holes 37 are provided on the box body 33 and the box cover 32.

[0049] In some embodiments, the anti-drop buckle 333 extends along the length direction of the box body 33 to both ends of the box body 33. Fig.12 and Fig.14 In this way, the contact area between the anti-drop buckle 333 and the box cover 32 is larger, and the limiting effect is better.

[0050] In some embodiments, the anti-drop buckle 333 is provided with a guide fold 3331, such as Fig.14 As shown, the guide fold 3331 is configured to guide the edge of the box cover 32 to snap into the anti-drop buckle 333. This facilitates the other end of the box cover 32 to be more smoothly embedded in the anti-drop buckle 333, and is not prone to stagnation, jamming, etc., thereby helping to improve the assembly efficiency of the electric control box 3.

[0051] In some embodiments, the anti-drop buckle 333 is surrounded by a groove with an opening toward the anti-drop slot 322, such as Fig.14 As shown, the guide fold 3331 is arranged at the notch of the groove. The anti-drop fold 334 extends in a direction away from the anti-drop buckle 333, as shown in FIG. Figure 5 The anti-drop groove 322 is arranged at the end of the sealing fold 323 in the length direction, as shown in FIG. Figure 7 and Fig.12 As shown. In this way, the cooperation between the anti-drop buckle 333 and the edge of the box cover 32 can limit the box cover 32 from sliding in the direction close to the anti-drop fold 334, and can also limit the box cover 32 from falling downward. The cooperation between the anti-drop fold 334 and the anti-drop groove 322 can limit the box cover 32 from falling downward, and can also limit the box cover 32 from sliding along the length direction of the box body 33 to a certain extent.

[0052] In some exemplary embodiments, the wiring parts of the box body 33 and the box cover 32 are provided with a folded edge thickening structure 35, which is helpful to prevent the wire body from being cut. The wiring parts can include the parts around the wiring hole 31 and the parts around the wiring gap. The folded edge thickening structure 35 can be formed by partially bending and overlapping the box body 33 or the box cover 32.

[0053] In some examples, the box body 33 and the box cover 32 are provided with a folded edge thickening structure 35 at the parts around the wiring hole 31, such as Figure 6 , Figure 8 and Fig.14 As shown, it is helpful to prevent the wires in the wiring hole 31 from being cut. The end of the sealing fold 323 of the box cover 32 is provided with a folded edge thickening structure 35, such as Fig.12As shown, this helps prevent the wires in the routing gap from being cut.

[0054] In some exemplary embodiments, the box body 33 and the box cover 32 are sheet metal parts, which, combined with the sealing structure of the electric control box 3, can effectively prevent the flames from escaping from the electric control box 3 after a fire occurs inside the electric control box 3, thereby improving the fire prevention performance.

[0055] In some exemplary embodiments, the box cover 32 is provided with a logo 324, such as Figure 4 As shown, the mark 324 is configured to indicate the installation direction and / or removal direction of the box cover 32. Therefore, the mark 324 plays an important role in the assembly and disassembly of the box cover 32 of the electric control box 3, and is conducive to improving the assembly and disassembly efficiency of the box cover 32.

[0056] The mark 324 may be, but is not limited to, a pointing arrow. Figure 4 As shown, the box cover 32 is provided with an arrow for indicating the disassembly direction of the box cover 32, for example, the direction from the anti-drop buckle 333 to the anti-drop slot 322. In this way, when installing, the box cover 32 can be installed in the opposite direction of the arrow until the edge of the box cover 32 is embedded in the anti-drop buckle 333, and the anti-drop folding edge 334 is also inserted into the anti-drop slot 322, so that the box cover 32 and the box body 33 are pre-positioned, and then the fastening screw is locked. When disassembling, first remove the locking screw, and then push the box cover 32 along the direction of the arrow until the edge of the box cover 32 is out of the anti-drop buckle 333 and the anti-drop folding edge 334 is out of the anti-drop slot 322, and then the box cover 32 can be removed.

[0057] The box body 33 can also be fixedly connected to the water receiving tray 5 or other structures of the air conditioner by means of fasteners such as locking screws, so as to ensure that the position of the box body 33 remains stable after the box cover 32 is removed during the subsequent maintenance process.

[0058] In some exemplary embodiments, the box body 33 is provided with a grounding hole, and a grounding screw 36 is passed through the grounding hole. Fig. 9 As shown. The grounding screw 36 has both a grounding function and an effective fire prevention function. The grounding hole of the box body 33 can be equipped with the grounding screw 36 when the incoming materials are installed.

[0059] like Figure 1 and Figure 2 As shown, an embodiment of the present application further provides an air conditioner, comprising a casing 1 and an electric control box 3 of any one of the above embodiments, wherein the electric control box 3 is disposed in the casing 1 .

[0060] The air conditioner provided in the embodiment of the present application comprises the electric control box 3 of any one of the above embodiments, and thus has all the above beneficial effects, which will not be described in detail here.

[0061] In some exemplary embodiments, the housing 1 is provided with an escape opening 16, such as Figure 1 and Figure 2 The avoidance opening 16 is connected to the wiring hole 31, as shown in FIG. Figure 2 and Figure 4 The wiring hole 31 is configured to allow the wire body passing through the avoidance opening 16 to extend into the electric control box 3. In other words, the external wire body 9 (such as a power line) can extend into the electric control box 3 through the avoidance opening 16 and the wiring hole 31, and connect to the main board or other components in the electric control box 3. The bottom wall of the wiring hole 31 is provided with a guide slope 321, as shown in FIG. Figure 2 and Fig.11 Along the direction close to the avoidance opening 16, the guide slope 321 extends downwardly.

[0062] In some exemplary embodiments, considering the structure of the air conditioner itself, the air conditioner can be an indoor unit of a split air conditioner, or a split air conditioner as a whole (casing 1 refers to casing 1 of the indoor unit); the air conditioner can also be an integrated air conditioner. Considering from the perspective of usage scenarios, the air conditioner can be but not limited to a kitchen air conditioner or a bathroom air conditioner. Considering from the perspective of installation methods, the air conditioner can be but not limited to an embedded air conditioner. An embedded air conditioner can be embedded in the ceiling of a kitchen or bathroom.

[0063] In some exemplary embodiments, the housing 1 includes a housing body 11 and a panel device 12. Figure 1 , Figure 2 and Figure 3 As shown. The panel device 12 is located at the lower side of the casing body 11 and is connected to the casing body 11. A middle partition (not shown in the figure) is provided in the casing body 11, and the middle partition divides the internal space of the casing body 11 into a fan chamber and a heat exchange chamber. The electric control box 3 is located at the lower side of the heat exchange chamber, and a fan assembly can be arranged in the fan chamber, and a heat exchanger can be arranged in the heat exchange chamber.

[0064] Take the embedded air conditioner as an example. After installation, Figure 1 and Figure 2 As shown, the panel device 12 is at the bottom and the housing body 11 is at the top. However, during the assembly process before leaving the factory, the air conditioner can be turned upside down, that is, the housing body 11 is at the bottom and the panel device 12 is at the top, so as to reduce the difficulty of assembling the air conditioner. The up and down directions marked in the drawings of this application specification are based on the state of assembly after leaving the factory.

[0065] In summary, the electric control box and air conditioner provided in the embodiments of the present application have improved the structure of the electric control box, which can effectively prevent water from entering the interior of the electric control box, and can achieve rapid disassembly and assembly of the electric control box, which is easy to maintain, has good fireproof performance, and has a simple structure and low cost.
