Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to a hidden-nail frameless air conditioning unit structure. Background Technology

[0002] In air handling units, traditional air conditioning units typically employ a main frame to ensure structural strength, with exposed fasteners between panels and the frame, and between panels themselves. This design presents several technical drawbacks: First, exposed nail heads not only detract from the aesthetics of the equipment but also pose a safety hazard by easily scratching people in high-traffic areas. Furthermore, exposed nail heads can lead to water seepage at the nail holes, reducing the equipment's corrosion resistance and lifespan. Second, traditional air conditioning units often use a double-layer panel structure, requiring foam insulation material between the two layers. This demands sophisticated processing equipment, increases manufacturing costs, and complicates the manufacturing process. Third, the main frame structure not only increases material costs but also enhances the complexity of the installation process, extending production and installation time and reducing production efficiency. Fourth, the connections in traditional air conditioning units often involve welding, which generates pollution and is prone to corrosion and deformation at the weld joints, affecting structural stability.

[0003] In addition, some air handling scenarios do not require heat exchange, and traditional air conditioning units with main frames and double-layer panels have functional redundancy, resulting in unnecessary cost waste.

[0004] In view of the problems existing in the above-mentioned existing technologies, it is necessary to study and design a new type of hidden nail frameless air conditioning box structure to overcome the problems existing in the existing technologies. Utility Model Content

[0005] To address the technical problems raised in the prior art, this invention provides a concealed-nail frameless air conditioning unit structure. This utility model primarily achieves concealed-nail connections through panels, fastening screws, and flap holes. Multi-layered structural reinforcement is achieved through reinforcing corner pieces, reinforcing ribs, and wind deflectors. While eliminating the traditional main frame and using a single-layer panel, the structural strength and load-bearing capacity of the air conditioning unit are guaranteed. Thermal insulation and sealing are achieved through panel insulation materials, inter-panel insulation materials, and sealant, ensuring effective air handling. The entire process utilizes fastener connections without welding, improving production and installation efficiency. The concealed-nail design eliminates the safety hazards and aesthetic defects associated with exposed nail heads.

[0006] The technical means adopted in this utility model are as follows: A frameless air conditioning unit structure with concealed nails includes: a panel, fastening screws, flap holes, panel insulation, reinforcing corner pieces, reinforcing ribs, inter-panel insulation, sealant, and a wind deflector; Furthermore, the panel is a single-layer panel; five panels are spliced ​​together to form the main structure of the air conditioning unit, eliminating the traditional main frame design of the air conditioning unit; Furthermore, two adjacent panels are connected by a concealed screw-type panel link structure through the edge flap holes and fastening screws; Furthermore, the air conditioning unit forms a multi-layered structural reinforcement system through reinforcing corner pieces, reinforcing ribs, and wind deflectors; Furthermore, the air conditioning unit forms an insulation and sealing structure through panel insulation materials, inter-panel insulation materials, and sealant; Furthermore, the air conditioning unit is also equipped with an inspection door.

[0007] Furthermore, the edges of both panels are processed into C-shaped bending structures, wherein a flap hole is provided at the second bend of the first panel, and a large mounting hole is provided at the position corresponding to the flap hole at the first bend of the second panel. Furthermore, after the fastening screw passes through the large mounting hole, it is threaded into the flip-up hole. The head of the fastening screw is hidden inside the bend of the panel, so that there is no exposed screw head on the outer surface of the panel, realizing a concealed screw connection and eliminating safety hazards.

[0008] Furthermore, the panel material is adhered to the inside of the panel; Furthermore, interpanel material is used to fill the joint between two adjacent panels; Furthermore, the sealant is applied at the joint between the panel and the outer edge of the insulation material. Furthermore, the panel insulation material, inter-panel insulation material, and sealant work together to achieve overall insulation of the air conditioning unit and waterproof sealing at the joints, effectively reducing the air leakage rate of the air conditioning unit and preventing moisture infiltration.

[0009] Furthermore, the corner of the air conditioning unit is a three-panel splicing structure, with reinforcing corner brackets attached to the inner corner formed by the splicing of the three panels. The reinforcing corner brackets are fixed to each panel with fastening screws, linking the five panels of the air conditioning unit into an integrated structure, strengthening the structural strength of the corner, and preventing deformation and cracking at the corner due to stress.

[0010] Furthermore, the inner side of the panel is evenly distributed with reinforcing ribs along its length and width; Furthermore, the reinforcing ribs are fixedly connected to the panel using fasteners; Furthermore, reinforcing ribs are used to improve the structural rigidity and load-bearing capacity of the panel, meeting the strength requirements for use of the air conditioning unit.

[0011] Furthermore, the wind deflector is located inside the air conditioning unit; Furthermore, the edge of the wind deflector is tightly abutted against the inside of the panel and is fixedly connected by fastening screws; Furthermore, the baffle plate secures the five panels of the cabinet into a whole, achieving secondary reinforcement of the air conditioning unit. At the same time, the baffle plate can guide the airflow inside the cabinet, improving the air humidification, filtration, and dehumidification effects.

[0012] Furthermore, the access door is connected to the panel by fastening screws in a concealed nail manner, and sealant is provided at the joint between the access door and the panel.

[0014] Furthermore, all connecting components between the panel, reinforcing corner pieces, reinforcing ribs, and wind deflector are fixed by fastening screws, eliminating the need for welding. This avoids environmental pollution caused by welding, reduces the technical requirements for processing personnel, and improves production and installation efficiency.
