Description

Technical Field

[0001] This utility model relates to the technical field of duct air conditioners, specifically an air conditioner duct unit with an easily detachable air outlet. Background Technology

[0002] Ductless air conditioners, or simply ducted units, are a simplified form of central air conditioning. They employ a one-to-one structure, meaning one outdoor unit is connected to one indoor unit. Air is evenly distributed through ducts, avoiding direct airflow onto people. During installation, they are concealed within the ceiling, offering an aesthetically pleasing look and saving floor space. For aesthetic reasons, existing ductless units often feature air outlet grilles at the vents. These grilles divide the air outlets into linear sections. Common installation methods for these grilles include narrow-edge and recessed types. Narrow-edge grilles have horizontal and vertical panels molded as a single piece, allowing them to be directly secured to the ceiling opening using plastic clips along the edges. Recessed grilles have separate horizontal and vertical panels; the horizontal panels are secured to the vertical panels using slots, while the vertical panels require bolts for fixing. At the ceiling opening, the evaporator surface of the ducted air conditioner needs to be regularly inspected and cleaned of dust and impurities during use. Traditional narrow-edge air outlet grilles protrude beyond the ceiling after installation, affecting the overall integrity. They are secured to the ceiling opening with plastic clips at the edges, requiring a flathead screwdriver to be inserted into the gaps at the edges for blind removal. This is not only difficult to remove but also prone to breaking the clips, affecting subsequent installation. Embedded air outlet grilles require multiple bolts to fix the vertical plates to the ceiling opening, which is inconvenient when removing and installing the vertical plates. When removing and installing the horizontal plates, the slots lack positioning, which can easily lead to misalignment of the horizontal plates, affecting the aesthetics. Therefore, we propose an air conditioning ducted air conditioner with an easily detachable air outlet. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This embodiment provides a technical solution: an air conditioning duct unit with an easily detachable air outlet, including an air conditioning housing 1 and a quick-release mechanism 3; Air conditioner housing 1: Both the upper and lower ends of its front side are equipped with base plates 2. The front end of the air conditioner housing 1 is the air outlet. The base plates 2 are fixedly connected to the front end of the air conditioner housing 1 by bolts. When installing the air outlet structure for the first time, the base plates 2 are connected to the air conditioner housing 1 by bolts. Subsequent disassembly and assembly of the air outlet structure does not require disassembly of the base plates 2. It also includes an evaporator 4, which is located inside the upper front side of the air conditioner housing 1. The evaporator 4 consists of copper tubes and fins. The evaporator 4 absorbs indoor heat to evaporate the refrigerant, thereby lowering the room temperature. A water collection box 5 is located at the lower front end of the interior of the air conditioning housing 1. The bottom wall of the water collection box 5 is distributed with a lower front and a higher rear. Drain pipes 6 are located on both the left and right front ends of the water collection box 5.

A return air inlet 9 is provided on the rear side of the lower end of air conditioner housing 1. The return air inlet 9 is vertically adjacent to impeller 7. When impeller 7 rotates, indoor air is drawn in through return air inlet 9. When passing through evaporator 4, the air is cooled by heat exchange and then blown out from air outlet. A heating wire can be added between impeller 7 and evaporator 4 for auxiliary heating in winter, providing a basis for the air intake and exhaust of the ducted air conditioner. An outdoor unit 10 is placed at the lower end of air conditioner housing 1. The input end of outdoor unit 10 is electrically connected to an external control unit. The air conditioner outdoor unit 10 contains a compressor (which is the core component for compressing refrigerant), a condenser (composed of copper tubes and fins, connected to the evaporator 4, responsible for heat exchange and heat dissipation), a fan and motor (driving the fan blades to accelerate airflow), a four-way valve (controlling the switching between cooling and heating), and throttling devices such as capillary tubes and expansion valves (regulating refrigerant flow and pressure), which are common in the prior art. The air conditioner indoor unit and the air conditioner outdoor unit 10 together form a ducted air conditioner, which is common in the prior art, providing a basis for the compression of refrigerant and heat exchange in the ducted air conditioner. Quick-release mechanism 3: It includes a snap-fit ​​bracket 31, a snap-fit ​​slot 32, a grid plate 33, a positioning post 34, and a fixing component 35. Movable snap-fit ​​brackets 31 are provided on the front sides of the two base plates 2. Snap-fit ​​slots 32 are evenly spaced on the front sides of the snap-fit ​​brackets 31. Evenly distributed notches are provided at the upper front end of the snap-fit ​​slots 32 to facilitate deformation. A grid plate 33 is snapped into each laterally adjacent snap-fit ​​slot 32. The grid plate 33 is bent downwards, and its rear end is cylindrical. The height of the rear end of the grid plate 33 is greater than the height of the middle part of its outer surface. The height of the front side inside the snap-fit ​​slot 32 is smaller. At the height of the inner rear side, the positioning posts 34 are all set in the middle of the rear side wall of the slot 32. The rear end of the inner side of the grid plate 33 has evenly distributed positioning holes. The outer surface of the positioning posts 34 is inserted into the inner wall of the longitudinally adjacent positioning holes, providing a basis for the quick assembly and disassembly of the grid plate 33. The fixing component 35 is set between the snap-fit ​​bracket 31 and the base plate 2. The fixing component 35 includes sliding posts 351 and sliding holes 352. The sliding posts 351 are evenly distributed on the front side of the base plate 2. The sliding holes 352 are respectively opened at the upper and lower ends of the inner rear side of the snap-fit ​​bracket 31. The interior of the sliding holes 352 is slidably connected to the outer surface of the longitudinally adjacent sliding posts 351, which is the base for the snap-fit ​​bracket 31. The quick assembly and disassembly of the snap-fit ​​bracket 31 provides a basis for this. The fixing assembly 35 also includes fixing holes 353, fixing grooves 354, and inserts 355. The fixing holes 353 are respectively located on the left and right sides of the upper and lower ends of the inner center of the snap-fit ​​bracket 31. The fixing grooves 354 are all located on the left and right sides of the inner center of the inner center of the substrate 2. The inserts 355 are all inserted into the interior of the fixing grooves 354. The middle part of the outer surface of each insert 355 is inserted into the inner wall of the longitudinally adjacent fixing holes 353, providing a basis for fixing and releasing the snap-fit ​​bracket 31. The fixing assembly 35 also includes protrusions 356 and clearance openings 357. The protrusions 356 are respectively located on the upper and lower ends of the middle part of the outer surface of the insert 355. The inner wall of the fixed groove 354 is provided with a groove in the middle. The outer surface of the protrusion 356 is installed in conjunction with the vertically adjacent groove. The protrusion 356 can be stuck in the groove. The clearance opening 357 is opened in the middle of the inside of the insertion post 355. The snap bracket 31, the grille plate 33 and the insertion post 355 are all made of ABS plastic, which can undergo plastic deformation, providing a basis for fixing and releasing the insertion post 355. The embedded design is neat and beautiful. No bolt connection is required during disassembly and assembly. The grille plate 33 can be accurately disassembled and assembled, and the snap bracket 31 can be quickly disassembled and assembled, which improves the disassembly and assembly efficiency of the air outlet of the duct unit and facilitates the cleaning and maintenance of the duct unit.

[0017] The working principle of the easily detachable air outlet duct unit provided by this utility model is as follows: When installing the air outlet of the air duct unit, first use bolts to fix the base plate 2 to the upper and lower ends of the front side of the air conditioner housing 1 respectively. After that, the base plate 2 does not need to be moved during disassembly and assembly. Then, the sliding hole 352 on the snap-fit ​​bracket 31 is offset from the sliding post 351, so that the sliding hole 352 is located to the left of the sliding post 351. Align the center of the sliding hole 352 with the center of the sliding post 351, and move the snap-fit ​​bracket 31 to the left so that the sliding post 351 and the corresponding sliding hole 352 are inserted into each other. The snap-fit ​​bracket 31 will not move back and forth or up and down due to the limitation of the sliding post 351. When the snap-fit ​​bracket 31 is moved to the left to the maximum extent, the fixing hole 353 and the fixing groove 354 are longitudinally adjacent. Pinch the front side of the insertion post 355. At both ends, the upper and lower parts of the insert 355 deform inward simultaneously, and the protrusion 356 also moves inward at the same time. The clearance opening 357 provides clearance for the deformation of the upper and lower parts of the insert 355. After the insert 355 deforms, the diameter of the front side of the outer surface of the insert 355 becomes smaller overall. The insert 355, together with the protrusion 356 on its surface, can be easily inserted into the fixing groove 354. After the insert is inserted into place, the front side of the insert 355 is released, and the insert 355 returns to its original shape. The protrusion 356 enters the corresponding groove. At this time, the middle part of the outer surface of the insert 355 is inserted into the inner wall of the longitudinally adjacent fixing hole 353. The insert 355 is limited by the groove and the protrusion 356 and will not move back and forth. Therefore, at this time, the snap-fit ​​bracket 31 is supported by the insert 355. The limit of 5 will not move left or right, and the snap-fit ​​bracket 31 is completely fixed. Then, pick up the grille plate 33 and align the arrow mark in the middle of the upper end of the grille plate 33 with the positioning post 34 in the middle. First, snap the rear end of the grille plate 33 into the opening on the front side of the slot 32. Push the grille plate 33 backward with force. The pushing force causes the grille plate 33 to press against the inner wall of the slot 32. Since each slot 32 has evenly distributed notches on the upper front side, when the slot 32 is compressed, the notches provide a clearance effect. The upper end of the slot 32 will deform upward. The deformation will increase the height of the slot 32 to accommodate the rear end of the grille plate 33, so that the rear end of the grille plate 33 can enter the inner rear side of the slot 32. After the rear end of the grille plate 33 enters the inner rear side of the slot 32, the snap-fit ​​bracket... The inner front side of the groove 32 returns to its original shape under no force, and then fits tightly against the middle of the outer surface of the grille 33. During this process, as the grille 33 is inserted, the positioning post 34 also inserts into the corresponding positioning hole, ensuring that the grille 33 will not shift left or right during insertion. When simple cleaning of the duct unit is required, simply remove the grille 33 and pull it outward. The inner front side of the slot 32 deforms under force, providing clearance for the grille 33, allowing it to be quickly pulled out of the slot 32. When deep cleaning and maintenance of the duct unit is required, the clip bracket 31 must also be removed. Pinch the front side of the insertion post 355 to deform it, causing the protrusion 356 to separate from the groove, allowing the insertion post 355 to be quickly pulled out.At this point, the snap-fit ​​bracket 31 loses its lateral limit. Move the snap-fit ​​bracket 31 to the right until the sliding hole 352 and the sliding post 351 are misaligned. Then the snap-fit ​​bracket 31 can be removed.

[0018] It is worth noting that the motor 8 disclosed in the above embodiments can be a Z2D15-24A-13S motor, and the air conditioner outdoor unit 10 can be an RND05AAY air conditioner outdoor unit. The external controller controls the operation of the motor 8 and the air conditioner outdoor unit 10 using methods commonly used in the prior art.

[0019] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
