Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to an air outlet flange structure for a ducted air conditioner. Background Technology

[0002] Air conditioning equipment typically includes a ducted unit to facilitate heat exchange between the indoor space and the air conditioner. The ducted unit is the connecting component that enables this heat exchange. It generally includes a copper pipe array (usually the condenser end of the copper pipe, which facilitates heat exchange between the cooler fluid and the indoor space) and a fan.

[0003] The air outlet flange is the fluid outlet, and its design primarily ensures the overall structural stability of the duct unit and the installation of louvers or fans. However, existing air outlet flanges have the following shortcomings:

[0004] 1. The air outlet flange consists of four separate parts, which are welded together to form a rectangular frame. Its structural strength is relatively poor. When the fluid flow rate and flow pressure are high, local deformation is prone to occur, which in turn affects the user experience (such as noise or abnormal rattling of the metal sheet).

[0005] 2. It requires four welding operations, which is a long process, slow processing efficiency, and poor product consistency (it requires four welding positioning operations, so the tolerance of the four right angles is large), which does not conform to standardized production and affects product quality. Utility Model Content

[0006] The main purpose of this utility model is to propose an air outlet flange structure for a duct air conditioner, which aims to improve the structural strength of the air outlet flange by constructing a rectangular frame through two bending components, while reducing welding processes, improving product quality and consistency, and increasing production efficiency.

[0007] To achieve the above objectives, this utility model proposes an air outlet flange structure for a ducted air conditioner, comprising:

[0008] The housing is equipped with a fan, and the fan has a fluid outlet in the direction of fluid flow.

[0009] A flange assembly is provided at a fluid outlet. The flange assembly is rectangular and includes two L-shaped frames that form a rectangular flange frame.

[0010] The L-shaped frame is integrally bent;

[0011] The L-shaped frame includes a frame portion and a positioning portion that bends inward at a 90-degree angle from the frame portion, the positioning portion being fitted to the side wall of the box body;

[0012] The adjacent ends of the two L-shaped frames are fixed by welding or angle iron.

[0013] In the actual design, this application changed from 4 parts to 2 materials, the welding length is less, the welding time is effectively shortened, and the production efficiency is effectively improved.

[0014] Meanwhile, due to the integrated structural design, the number of screws used to fix the flange has been reduced from 12 to 8, a reduction of 1 / 3, saving assembly time.

[0015] By optimizing the flange structure design, the integrated sheet metal design reduces welding processes and the cumbersome handling of multiple materials, thereby improving production efficiency. At the same time, the integrated bent L-shaped frame ensures the strength of the flange, and the assembly line can also reduce the number of fixing screws, further shortening the working time.

[0031] like Figures 1 to 5 As shown, an air outlet flange structure for a ducted air conditioner includes,

[0032] The housing 1 is equipped with a fan 10, and the fan 10 has a fluid outlet 11 in the fluid direction;

[0033] Flange assembly 2, the flange assembly 2 is located at fluid outlet 11, the flange assembly 2 is rectangular, the flange assembly 2 includes two L-shaped frames 20, the two L-shaped frames 20 form a rectangular flange frame;

[0034] The L-shaped frame 20 is integrally bent;

[0035] The L-shaped frame 20 includes a frame portion 22 and a positioning portion 21 that bends inward at a vertical angle (90 degrees) from the frame portion 22. The positioning portion 21 is in contact with the side wall of the box body 1.

[0036] The adjacent ends of the two L-shaped frames 20 are fixed by welding or angle iron.

[0037] In the actual design, this application changed from 4 parts to 2 materials, the welding length is less, the welding time is effectively shortened, and the production efficiency is effectively improved.

[0038] Meanwhile, due to the integrated structural design, the number of screws used to fix the flange has been reduced from 12 to 8, a reduction of 1 / 3, saving assembly time.

[0039] By optimizing the flange structure design, the integrated sheet metal design reduces welding processes and the cumbersome handling of multiple materials, thereby improving production efficiency. At the same time, the integrated bent L-shaped frame 20 ensures the strength of the flange, and the assembly line can also reduce the number of fixing screws, further shortening the working time.

[0040] Specifically, the L-shaped frame 20 includes a first side frame 201 and a second side frame 202, i.e., two sections. Of course, in actual production, a fully integrated structure can also be achieved, but compared to a two-section structure, its processing time is shorter.

[0041] In this embodiment of the utility model, the first side frame 201 and the second side frame 202 are integrally bent from the same plate 3.

[0042] The plate 3 includes a main body, a first bending line 31 along the width direction, a second bending line 32 located in the middle of the main body, and a diamond-shaped groove 33 located above the second bending line 32. The diamond-shaped groove 33 is symmetrically arranged about the center line of the plate 3.

[0043] The first bending mark 31 is used to form the frame part 22 and the positioning part 21, and the diamond-shaped groove is provided between the positioning parts 21.

[0044] The second crease is used to form the first side frame 201 and the second side frame 202.

[0045] Specifically, the angle of the rhomboid groove is 90 degrees, so that the first and second inclined surfaces of the rhomboid groove abut each other after bending, thereby improving the structural strength and eliminating the need for fixed welding.

[0046] In this embodiment of the utility model, the first bending line forms an upper plate and a lower plate. The upper plate has a protruding rib 4 in the direction of the housing 1. The inner side of the protruding rib 4 forms a groove 40. The difference from the existing structure is that the setting of the protruding rib can improve the structural strength of the air outlet and also effectively improve the structural strength of the flange.

[0047] In actual processing, the first plate body 3 is first formed with protruding ribs (stamping), and then the predetermined diamond grooves are cut.

[0048] Then, the positioning part and the frame part are bent at the first bend line as the fulcrum;

[0049] Then, using the second crease as a fulcrum, a second bend is made to form an L-shaped frame 20.

[0050] Specifically, the ribs are distributed or spaced apart along the length of the upper plate.

[0051] In this embodiment of the invention, the groove is coated with an elastic adhesive layer. In actual design, to improve the noise reduction effect, the existing practice is generally to design a sealing ring for fit and installation;

[0052] Existing sealing rings are mainly flat plate structures, which require special customization;

[0053] However, the width of the rib is relatively small, and even if an O-ring is installed, the installation time and difficulty are relatively large. The coated elastic adhesive layer can effectively achieve a fitting effect and improve the sound insulation effect. It mainly plays a buffering role and reduces resonance.

[0054] The setting of the elastic adhesive layer is mainly changed according to customer needs and environmental requirements;

[0055] The application of adhesive can be done by automated robots or manually.

[0056] Specifically, the positioning part 21 is provided with multiple screw through holes 5, which facilitates its installation.

[0057] In this embodiment of the invention, the groove is semi-circular or rectangular.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
