Description

Technical Field

[0001] This utility model relates to the field of ceiling machine structure technology, specifically to a surface panel assembly and its ceiling machine. Background Technology

[0002] In modern building environments and air conditioning systems, ceiling-mounted air conditioning units (i.e., ceiling-embedded air conditioning units) serve as efficient and aesthetically pleasing indoor temperature control solutions. Their design not only concerns cooling / heating performance but also directly impacts the visual appeal and air distribution efficiency of the interior space. The ceiling panel components, acting as a bridge connecting the unit's internal structure to the external environment, fulfill multiple functions, including guiding airflow, enhancing the appearance, and protecting internal components. Their design rationality directly affects the user experience and the overall efficiency of the equipment.

[0003] With the development of intelligent and automated technologies, some high-end ceiling air conditioners have begun to introduce stepper motor-driven louver systems to automatically adjust the direction of the air outlets, improving the uniformity and comfort of air distribution. However, in existing technologies, the wiring layout of stepper motors often lacks proper planning, leading to messy and disorganized wiring, increased maintenance difficulty, and even safety hazards. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface panel assembly and its ceiling machine, so as to solve the problem that the connection line layout of the stepper motor is often not rationally planned, which easily leads to messy and disorderly wiring, increases maintenance difficulty, and even poses safety hazards.

[0005] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a panel assembly, including a panel, on which an air inlet is formed and a plurality of main air outlets are distributed circumferentially around the outside of the air inlet, and each main air outlet is provided with a swing blade driven by a stepper motor, wherein the stepper motor is located in the mounting area on the outside of one end of the corresponding main air outlet.

[0006] Furthermore, each of the main air outlets and air inlets has a stepper motor wiring area through which the connecting wires of the corresponding stepper motors pass, and the stepper motor wiring area is slidably snapped with a cover plate for sealing.

[0007] The second aspect of this utility model adopts the following technical solution: a ceiling machine, including a surface panel assembly as described in the first aspect of this utility model.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This panel assembly features a stepper motor wiring area between each main air outlet and air inlet, through which the corresponding stepper motor wiring passes. This allows for a rational arrangement of the stepper motor wiring, while a cover plate seals the wiring area, ensuring a safe and efficient layout. Furthermore, removing the cover plate allows for quick and easy maintenance and inspection of the stepper motor wiring. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below through specific embodiments:

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, this utility model embodiment proposes a ceiling machine, including a panel assembly and other existing structures. The panel assembly includes a panel 1, on which an air inlet is formed and a plurality of main air outlets 3 are distributed circumferentially around the outside of the air inlet. Each main air outlet 3 is equipped with a louver 4 driven by a stepper motor 2. The stepper motor 2 is located in the mounting area on the outside of one end of the corresponding main air outlet 3. Furthermore, a stepper motor 2 wiring area is formed between each main air outlet 3 and the air inlet for the connecting wire of the corresponding stepper motor 2 to pass through, and a cover plate 6 is slidably engaged with the stepper motor 2 wiring area to seal it.

[0024] This panel assembly features a wiring area between each main air outlet 3 and air inlet, allowing the connecting wires of the corresponding stepper motor 2 to pass through. This arrangement rationally arranges the connecting wires of the stepper motor 2. Simultaneously, a cover plate 6 seals the wiring area, ensuring a safe and reasonable layout for the connecting wires. Furthermore, removing the cover plate 6 allows for quick and easy maintenance and inspection of the connecting wires of the stepper motor 2.

[0025] In this embodiment, the panel 1 is square and integrally formed, reducing the use of screws; the air inlet is located in the middle of the panel 1, so that the air intake surface is sufficient; there are four main air outlets 3, which are distributed one-to-one on the four sides of the panel 1.

[0026] To better understand this solution, it will be further described below.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, according to another embodiment of the present invention, the surface panel assembly includes an air inlet suction grille 7 at the air inlet, and between each main air outlet 3 and the air inlet, there are also air inlet suction grille 7 mounting areas located outside the wiring area of ​​the stepper motor 2, which provide installation space for the connectors on the air inlet suction grille 7 during installation, and foam insulation areas 9 for heat preservation of the corresponding main air outlet 3. The cover plate 6 also seals the corresponding air inlet suction grille 7 mounting areas and foam insulation areas 9.

[0028] In this embodiment, the air inlet suction grille 7 is installed at the air inlet for protection, preventing insects and other pests from entering the ceiling machine through the air inlet.

[0029] The air inlet is also square, so the air inlet suction grille 7 is also square, and each of the four sides of the air inlet suction grille 7 is provided with a connector. When the air inlet suction grille 7 is installed, the connectors on the four sides of the air inlet suction grille 7 are embedded into the four air inlet suction grille 7 installation areas one by one. After the cover plate 6 is installed, the cover plate 6 not only seals the corresponding stepper motor 2 wiring area, the air inlet suction grille 7 installation area and the foam insulation area 9, but also limits the connectors of the air inlet suction grille 7 to ensure the stable installation of the air inlet suction grille 7.

[0030] The foam insulation zone 9 is designed to prevent condensation from forming at the main air outlet 3.

[0031] To ensure a quick and stable connection of the cover plate 6, such as Figure 5 , Figure 6 as well as Figure 7 As shown, according to another embodiment of the present invention, in a surface panel assembly, the cover plate 6 is fixed by a snap-fit ​​structure 10. The snap-fit ​​structure 10 includes a first protrusion 101 and a buckle 102. Multiple first protrusions 101 are arranged at intervals along the installation direction of the cover plate 6 in both the stepper motor 2 wiring area and the foam insulation area 9. Multiple buckles 102 are fixedly connected to the inner side of the cover plate 6, and the multiple buckles 102 slide into the limiting area formed below the multiple first protrusions 101.

[0032] In this embodiment, the number of first protrusions 101 arranged in the wiring area of ​​the stepper motor 2 and the foam insulation area 9 are both four, and the number of buckles 102 is eight, arranged in two rows of four. Among them, the first protrusions 101 are strip-shaped blocks, and the buckles 102 are "L"-shaped.

[0033] When cover plate 6 is installed:

[0034] Place the cover plate 6 in the initial pre-installation position;

[0035] Slide the cover plate 6 along its length, and one end of the buckle 102 slides against the bottom of the first protrusion 101 one by one until the cover plate 6 slides to the final installation position, thus completing the sealing of the corresponding stepper motor 2 wiring area, air inlet suction grille 7 installation area and foam insulation area 9.

[0036] In order to improve the assembly accuracy of the cover plate 6, one side of the cover plate 6 is bent to form a first folded edge structure 11 for limiting and abutting against the inner side of the wiring area of ​​the stepper motor 2.

[0037] Here, the cross-section of the first folded edge structure 11 is specifically right-angled. During the installation of the cover plate 6, the first folded edge structure 11 abuts against the inner side of the wiring area of ​​the stepper motor 2 to limit the cover plate 6 and improve the assembly accuracy of the cover plate 6.

[0038] The cover plate 6 has a second protrusion 12 at both ends along its length; after the cover plate 6 is installed, the second protrusion 12 can limit the remaining structure in the face panel assembly.

[0039] Furthermore, each first protrusion 101 in the wiring area of ​​the stepper motor 2 is surrounded by a perimeter structure 13, and the perimeter structure 13 has a sliding area for the corresponding buckle 102 to slide into; each perimeter structure 13 is provided with a wire-blocking structure 14 for limiting the connection wire.

[0040] In this embodiment, the surrounding structure 13 is U-shaped and its two ends are connected to the inner sidewall of the wiring area of ​​the stepper motor 2 to surround the outer side of the corresponding first protrusion 101, so as to prevent the connecting wires arranged in the wiring area of ​​the stepper motor 2 from getting close to the first protrusion 101 and causing the wire jamming problem when the cover plate 6 is installed.

[0041] Furthermore, the wire-blocking structure 14 is a square block, and a certain gap is formed between this square block and the bottom of the stepper motor 2 wiring area. The connecting wire passes through this gap, and the wire-blocking structure 14 limits the connection wire, thereby improving the stability of the connection wire arrangement in the stepper motor 2 wiring area.

[0042] like Figure 3 , Figure 4 as well as Figure 8 As shown, according to another embodiment of the present utility model, in the surface panel assembly, the foam insulation zone 9 is provided with insulation foam 15. By arranging the insulation foam 15 in the foam insulation zone 9, the main air outlet 3 is insulated, so that no condensation will be generated at the main air outlet 3 when exhausting air.

[0043] The insulating foam 15 has a first limiting groove 151 that abuts against and limits the panel 1, a second limiting groove 152 that abuts against and limits the cover plate 6 when it slides in, and a clearance notch 153 that provides installation clearance for the corresponding buckle 102.

[0044] The cross-sections of the first limiting groove 151 and the second limiting groove 152 are both right angles. When the thermal insulation foam 15 is installed, the thermal insulation foam 15 abuts against the corresponding position on the panel 1 through the first limiting groove 151, thereby improving the installation accuracy of the thermal insulation foam 15. When the cover plate 6 is installed, one side of the cover plate 6 abuts against the inner side of the stepper motor 2 wiring area through the first folded edge structure 11, and the other side of the cover plate 6 abuts against the second limiting groove 152, thereby improving the installation accuracy of the cover plate 6 during the sliding installation process.

[0045] The notch 153 is designed to allow space for the corresponding buckle 102 during the installation of the cover plate 6, so that the corresponding buckle 102 can cooperate with the first protrusion 101 in the foam insulation area 9.

[0046] like Figure 1 , Figure 2 , Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, according to another embodiment of the present invention, in a panel assembly, an auxiliary air outlet 16 is provided between each of two adjacent main air outlets 3, and multiple installation areas are located one-to-one on the side of the multiple auxiliary air outlets 16 near the air inlet.

[0047] In this embodiment, there are four auxiliary air outlets 16 and four installation areas. The location design of the installation areas can provide installation space for the stepper motor 2, but will not affect the opening of the auxiliary air outlets 16.

[0048] To make the outer side of panel 1 neater and more aesthetically pleasing, each of the mounting areas is detachably connected with a seal 17 to seal the mounting area.

[0049] Each of the sealing elements 17 has a second folded edge structure 171 that cooperates with the limiting platform on the inner edge of the corresponding installation area and two third protrusions 172 that are correspondingly engaged with the second protrusions 12 on the cover plate 6 after installation on both sides; each second protrusion 12 has an angled guide structure 121 on one side for guiding the corresponding third protrusion 172 to its bottom for abutment and limiting.

[0050] The sealing element 17 is installed behind the cover plate 6. After the cover plate 6 is installed, a second protrusion 12 is embedded in the installation area on both sides of the installation area.

[0051] When seal 17 is installed:

[0052] The sliding seal 17 slides the second folded edge structure 171 of the seal 17 into the limiting platform of the inner edge of the corresponding installation area for limiting and fixing. At the same time, the oblique guide structure 121 guides the corresponding third protrusion 172 so that the two third protrusions 172 slide into the bottom side of the two second protrusions 12 one by one and are pressed and fixed.

[0053] Then, a screw is passed through the screw hole 173 on the seal 17 and threaded into the screw post in the installation area to ensure that the seal 17 is stably installed.

[0054] The structural design of the seal 17 reduces the use of screws.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
