[0003] Among them, a plurality of wiring components are arranged in the electronic control box for connecting various electronic components, sensors, motors, switches, etc. inside the air conditioner, so that the entire electronic control system forms a complete circuit; and the power supply is distributed to different components of the air conditioner, such as compressors, fan motors, heating elements, etc., to ensure that each component works under appropriate voltage and current.

[0004] However, there are at least the following problems in the related art: when a short circuit occurs in the wiring components in the electronic control box in the prior art, the wiring components are not easily detached, resulting in the wiring components remaining in a short-circuit state continuously, so that a large amount of heat generated during the short circuit accumulates at the wiring terminals, thereby increasing the risk of safety accidents. Summary of the Utility Model

[0005] The technical problem solved by the utility model is that when a short circuit occurs in the wiring components in the electronic control box in the prior art, the wiring components are not easily detached, resulting in the wiring components remaining in a short-circuit state continuously, so that a large amount of heat generated during the short circuit accumulates at the wiring terminals, thereby increasing the risk of safety accidents.

[0006] To solve the above problems, the utility model provides a ceiling air conditioner, which includes an electronic control box. The electronic control box includes: a storage housing; a cover body that cooperates with the storage housing to form a receiving cavity for receiving electrical connection components; a circuit board disposed in the receiving cavity; a wiring component disposed on the mounting side of the circuit board; a wire trough disposed in the storage housing for a wire to pass through to electrically connect the wiring component to an electronic component of the ceiling air conditioner; wherein, the distance between the wiring component and the cover body is defined as a first distance, and the distance between the wire trough and the cover body is defined as a second distance, and the first distance is greater than the second distance.

[0007] Compared with the prior art, the technical effect achieved by adopting this technical solution: when a short circuit occurs in the wiring components in the electronic control box, it is avoided that the wiring components are not easily detached, resulting in the wiring components remaining in a short-circuit state continuously, so that a large amount of heat generated during the short circuit accumulates at the wiring components, thereby improving the safety during the use of the ceiling air conditioner.

[0008] Specifically, in this solution, by setting the first spacing to be greater than the second spacing, when the wiring component is short-circuited to the circuit board, it can quickly fall off the circuit board under the action of its own gravity and the gravity of the wire, thus avoiding the situation where the wiring component remains in a short-circuit state continuously, reducing the risk of fire occurrence, and further improving the safety during the use of the ceiling unit.

[0009] In an example of the present utility model, the spacing value between the first spacing and the second spacing is 2 mm to 5 mm.

[0014] Specifically, when any one of them is short-circuited to the circuit board, under the combined action of its own gravity and the pulling force of the connecting wire, the short-circuited wiring terminal can quickly detach from the circuit board, thus avoiding the situation of continuously contacting the circuit board and affecting the electrical connection between other wiring terminals and the circuit board.

[0015] In an example of the present utility model, the first wiring terminal group includes a plurality of wiring terminals, and there is a first spacing distance between any two adjacent wiring terminals.

[0017] Specifically, through the design of having a first spacing distance between any two adjacent wiring terminals, the plurality of wiring terminals are independently arranged. When any one wiring terminal is short-circuited to the circuit board, under the combined action of its own gravity and the pulling force of the connecting wire, it can quickly detach from the circuit board, thus avoiding the influence on the electrical connection between other wiring terminals and the circuit board due to continuous contact with the circuit board, and further improving the safety during the use of the ceiling unit.

[0018] Further, there is a first spacing distance between any two adjacent terminal blocks, which is conducive to air circulation, reduces heat accumulation between multiple terminal blocks, thereby improving the heat dissipation performance of the first terminal block group and extending the service life of the circuit board.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is that when overhauling the electrical connection components inside the electric control box, it is convenient for maintenance personnel to disassemble and assemble the cover body.

[0021] In an example of the present utility model, the storage housing includes a first connecting portion and a second connecting portion arranged opposite to each other, and the cover body includes a third connecting portion and a fourth connecting portion arranged opposite to each other; wherein, when the cover body and the housing are in a matching state, the first connecting portion is connected to the third connecting portion, and the second connecting portion is connected to the fourth connecting portion.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the stability when the cover body and the housing are matched is improved.

[0023] In an example of the present utility model, the first connecting portion is provided with a first screw hole, the second connecting portion is provided with a second screw hole, the third connecting portion is provided with a third screw hole, and the fourth connecting portion is provided with a fourth screw hole; wherein, when the cover body and the housing are in a matching state, the first screw hole and the third screw hole are connected by screws, and the second screw hole and the fourth screw hole are connected by screws.

Detailed implementation mode

[0051] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0052] As Figures 1 to 15 shown, the present utility model provides a ceiling unit 100, which includes an electric control box 200. The electric control box 200 includes a storage housing 300, a cover 400, a circuit board 500, a wiring assembly and a wire trough 700. Among them, the cover 400 cooperates with the storage housing 300 to form a receiving cavity for receiving electrical connection components. The circuit board 500 is arranged in the receiving cavity, the wiring assembly is arranged on the installation side of the circuit board 500, and the wire trough 700 is arranged in the storage housing 300 for wires to pass through to electrically connect the wiring assembly with the electronic components of the ceiling unit 100. Define the distance between the wiring assembly and the cover 400 as the first distance, and the distance between the wire trough 700 and the cover 400 as the second distance. The first distance is greater than the second distance. Thus, when a short circuit occurs in the wiring assembly in the electric control box 200, the wiring assembly is not easily detached, resulting in the wiring assembly remaining in a short circuit state continuously, and a large amount of heat generated during the short circuit accumulates at the wiring assembly. Therefore, the safety during the use of the ceiling unit 100 is improved.

[0053] Specifically, in the prior art, when a short circuit occurs in the wiring assembly of the electric control box 200, the wiring assembly is not easily detached from the connection point, resulting in a large amount of heat generated during the short circuit accumulating at the connection point between the wiring assembly and the circuit board 500, causing the temperature to continue to rise, thereby increasing the risk of fire. In this solution, by setting the first distance to be greater than the second distance, when a short circuit connection occurs between the wiring assembly and the circuit board 500, the wiring assembly can quickly fall off the circuit board 500 under the action of its own gravity and the gravity of the wire, thus avoiding the situation where the wiring assembly remains in a short circuit state continuously, reducing the risk of fire, and further improving the safety during the use of the ceiling unit 100.

[0054] Furthermore, the distance value between the first distance and the second distance is 2 mm to 5 mm.

[0055] For example, in an embodiment of the present utility model, the distance value between the first distance and the second distance is preferably 2 mm.

[0056] Again, for example, in an embodiment of the present utility model, the distance value between the first distance and the second distance is preferably 5 mm.

[0057] Furthermore, as Figure 5 and Figure 6 shown, the distance value between the first distance and the second distance is preferably 3.4 mm. Thereby further improving the safety during the use of the ceiling unit 100.

[0058] Further, as Figures 10 to 13 shown, the wiring assembly includes a first wiring terminal group 600, and any one of the wiring terminals 610 in the first wiring terminal group 600 is electrically connected to the circuit board 500 through an electric wire.

[0059] It should be noted that the connection relationship between the first wiring terminal group 600 and the circuit board 500 in the embodiment of the present utility model is different from the connection relationship in the prior art. For the convenience of description, the wiring terminal group used to be electrically connected to the circuit board 500 in the prior art is defined as the second wiring terminal group. Specifically, the second wiring terminal group includes a plurality of interconnected second wiring terminals 610, and the plurality of second wiring terminals 610 together form a wiring portion, and the electrical connection between the second wiring terminal group and the circuit board 500 is realized through the electrical connection of the wiring portion to the circuit board 500.

[0060] Thus, by comparing the first wiring terminal group 600 and the second wiring terminal group, it can be seen that any one of the wiring terminals 610 in the above content is electrically connected to the circuit board 500, which is manifested as the plurality of wiring terminals 610 in the first wiring terminal group 600 being independently arranged from each other. When a short-circuit connection occurs between any one of the wiring terminals 610 and the circuit board 500, it is possible to avoid the situation where the wiring terminal 610 continuously contacts the circuit board 500, resulting in the spread of the short-circuit phenomenon to the circuit board 500 or the wiring terminals 610 where no short-circuit phenomenon occurs, thereby reducing the loss when a short-circuit connection occurs between the wiring terminal 610 and the circuit board 500.

[0061] More specifically, when a short-circuit connection occurs between any one of the wiring terminals 610 in the first wiring terminal group 600 and the circuit board 500, under the combined action of its own gravity and the pulling of the connecting wire, the short-circuited wiring terminal 610 can quickly detach from the circuit board 500, thereby avoiding the situation of continuously contacting the circuit board 500 and affecting the electrical connection between other wiring terminals 610 and the circuit board 500.

[0062] Furthermore, as Figures 1 to 15As shown, the first terminal group 600 includes a plurality of terminals 610, and there is a first spacing distance between any two adjacent terminals 610. This further improves the safety during the use of the ceiling unit 100.

[0063] Specifically, through the design of having a first spacing distance between any two adjacent terminals 610, the plurality of terminals 610 are independently arranged. When any one of the terminals 610 is short-circuited to the circuit board 500, under the action of its own gravity and the pulling of the connecting wire, it can quickly detach from the circuit board 500, thus avoiding continuous contact with the circuit board 500 and affecting the electrical connection between other terminals 610 and the circuit board 500. This further improves the safety during the use of the ceiling unit 100.

[0064] Furthermore, having a first spacing distance between any two adjacent terminals 610 is conducive to air circulation, reduces the heat accumulation between the plurality of terminals 610, thus improving the heat dissipation performance of the first terminal group 600 and extending the service life of the circuit board 500.

[0065] Further, the storage housing 300 and the cover 400 are separately provided and connected in a detachable manner; or the storage housing 300 and the cover 400 are integrally provided, and the cover 400 can avoid and accommodate the cavity through at least one of the following actions or a combination thereof: rotation, flipping, sliding, folding. This facilitates the disassembly and assembly of the cover 400 by maintenance personnel when overhauling the electrical connection components inside the electric control box 200.

[0066] Further, as Figures 1 to 4 shown, the storage housing 300 includes a first connecting portion 310 and a second connecting portion 320 arranged opposite to each other, and the cover 400 includes a third connecting portion 410 and a fourth connecting portion 420 arranged opposite to each other; wherein, as Figure 4 and Figure 4 shown, when the cover 400 and the housing are in a mating state, the first connecting portion 310 is connected to the third connecting portion 410, and the second connecting portion 320 is connected to the fourth connecting portion 420. This improves the stability when the cover 400 and the housing are mated.

[0067] Further, the first connecting portion 310 is provided with a first screw hole, the second connecting portion 320 is provided with a second screw hole, the third connecting portion 410 is provided with a third screw hole, and the fourth connecting portion 420 is provided with a fourth screw hole; wherein, when the cover body 400 and the housing are in a mating state, the first screw hole and the third screw hole are connected by a screw 800, and the second screw hole and the fourth screw hole are connected by a screw 800. In this solution, the first screw hole and the third screw hole are connected by a screw 800, and the second screw hole and the fourth screw hole are connected by a screw 800, thereby improving the sealing performance when the cover body 400 and the housing are mated, and further preventing dust from entering the accommodating cavity and damaging the electrical connection components in the electric control box 200.

[0068] Further, as Figures 1 to 12 shown, the first connecting portion 310 is provided with a card slot 311, and the third connecting portion 410 is provided with a buckle 411 that cooperates with the card slot 311; the second connecting portion 320 is provided with a fifth screw hole 321, and the fourth connecting portion 420 is provided with a sixth screw hole 421. When the cover body 400 and the housing are in a mating state, the fifth screw hole 321 and the sixth screw hole 421 are connected by a screw 800. Through the cooperation of the card slot 311 and the buckle 411 and the connection of the fifth screw hole 321 and the sixth screw hole 421 by a screw 800, the stability when the cover body 400 and the housing are mated is further improved.

[0069] Further, as Figures 1 to 12 shown, the card slot 311 is provided with at least one first protrusion 311a, and the buckle 411 is provided with at least one second protrusion 411a. As Figure 3 shown, when the buckle 411 is engaged with the card slot 311, the second protrusion 411a is buckled on the side of the first protrusion 311a away from the receiving housing 300. Through the buckling design of the first protrusion 311a and the second protrusion 411a, the fixing force between the card slot 311 and the buckle 411 is increased, making the connection between the card slot 311 and the buckle 411 more firm and not easily loosened or separated due to external forces, thereby further increasing the stability when the cover body 400 and the housing are mated.

[0070] For example, as Figures 1 to 12 shown, the card slot 311 is provided with two first protrusions 311a, and the buckle 411 is provided with two second protrusions 411a. As Figure 3 shown, when the buckle 411 is engaged with the card slot 311, the second protrusion 411a is buckled on the side of the first protrusion 311a away from the receiving housing 300.

[0071] Further, as Figures 1 to 15As shown in the figure, the ceiling unit 100 provided in the embodiment of the present utility model is provided with an inlet hole 110 for the power supply wire to enter the interior of the telephone set. A wire pressing seat 120 is also provided at a position opposite to the inlet hole 110 to prevent the wires in the ceiling unit 100 that do not extend into the electric control box 200 from shaking during the operation of the ceiling unit 100 and stretching the wires extending into the interior of the electric control box 200, so as to avoid the loosening of the connection between the wiring terminal of the wire extending into the interior of the electric control box 200 and the wiring terminal 610, thereby increasing the stability of the connection between the wires in the electric control box 200 and the wiring terminal 610.

[0072] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
