Technical Field

[0001] This application relates to the field of air duct installation technology, and more specifically, to an air duct installation structure for household appliances. Background Technology

[0002] The air duct installation structure of household appliances is a specific structure used to house the air ducts in household appliances. The air duct installation structures of different household appliances vary according to functional requirements, but together they provide support for the stable operation and efficient performance of household appliances.

[0003] In the home appliance industry, some air ducts employ a multi-section combined structure and are installed on the roof. This installation method has significant drawbacks: poor sealing performance between adjacent ducts and difficulty in achieving a tight fit at joints lead to airflow leakage. This reduces the ventilation efficiency of the duct system. Furthermore, traditional installation structures are difficult to install, requiring complex positioning tools and consuming considerable installation time and labor costs, severely hindering installation efficiency and cost control.

[0004] In view of this, this application proposes a duct installation structure for household appliances. Utility Model Content

[0005] The purpose of this application is to provide a duct installation structure for household appliances, which solves the technical problems mentioned in the background art.

[0006] This application provides a household appliance duct installation structure, including a pair of adjacent duct frames. A combination mechanism is provided at the ends of the adjacent duct frames that are close to each other. A fixing mechanism is provided around the combination mechanism, and a pair of mounting brackets are provided above the fixing mechanism. The combination mechanism includes a connecting frame fixedly connected to both ends of the duct frame. A movable frame is slidably connected to one side of the connecting frame, and a combination frame is fixedly connected to one side of the movable frame. The fixing mechanism includes fixing plates located above and below the adjacent duct frames. Slots are provided on the end faces of the two fixing plates that are close to each other, and the combination frame is located within the slots.

[0007] Optionally, a shaped silicone ring is fixedly fastened to one side of the combination frame, and the mounting bracket is fixedly connected to the fixing plate located above.

[0008] Optionally, a fixing strip is fixedly connected to one side of the fixing plate mentioned above. A sliding groove is provided on the lower part of the fixing strip near the end face of the fixing plate. A first threaded rod is rotatably connected inside the sliding groove, and the lower end of the first threaded rod extends out of the sliding groove.

[0009] Optionally, a sliding block is fixedly connected to one side of the fixed plate below, the sliding block extending into the sliding groove, and the sliding groove and the first threaded rod are rotatably connected by threads.

[0010] Optionally, a rotating block is rotatably connected to the other side of the fixed plate below. The rotating block is rotatably connected to a second threaded rod through a thread. One end of the second threaded rod is fixedly connected to an extension rod, and one end of the extension rod is rotatably connected to a positioning block.

[0011] Optionally, a limiting block is fixedly connected to the other side of the fixed plate mentioned above. The upper end face of the limiting block is provided with a positioning groove, and the lower ends of the second threaded rod and the first threaded rod are both fixedly connected with knobs.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] This application involves installing connecting frames, movable frames, and combination frames on both sides of the duct frame. Adjacent duct frames are lifted, and the combination frame is inserted between two fixed plates on the roof, fitting into a slot in the lower fixed plate. A first and second threaded rod move the lower fixed plate upwards, causing the combination frame to enter the slot in the upper fixed plate. Due to the inclined inner wall of the slot, the movement of the two fixed plates pushes the two combination frames closer together, ultimately ensuring a tight seal between the shaped silicone rings on the adjacent combination frames, achieving excellent sealing. This superior sealing prevents airflow leakage within the duct, ensuring the ventilation efficiency of the duct system, reducing energy consumption, and avoiding environmental impact caused by airflow leakage. Simultaneously, the two fixed plates clamp the combination frame, preventing wobbling at the connection point of adjacent duct frames. The sealing installation between duct frames is simple and direct, enabling rapid positioning and installation of the duct frames without complex positioning tools or operations, saving installation time.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-3 This application provides a household appliance duct installation structure, including a pair of adjacent duct frames 1. A combination mechanism 2 is provided at the close ends of the adjacent duct frames 1. A fixing mechanism 3 is provided around the combination mechanism 2, and a pair of mounting brackets 4 are provided above the fixing mechanism 3. The combination mechanism 2 includes a connecting frame 201 fixedly connected to both ends of the duct frame 1. A movable frame 202 is slidably connected to one side of the connecting frame 201, and a combination frame 203 is fixedly connected to one side of the movable frame 202. The connecting frame 201, movable frame 202, and combination frame 203 are installed on both sides of the duct frame 1. A shaped silicone ring 204 is fixedly snapped onto one side of the combination frame 203. The shaped silicone rings 204 on two adjacent combination frames 203 are fitted together. A silicone strip is provided on the fitting end face of one side of the shaped silicone ring 204, and a strip groove is provided on the fitting end face of the other side of the shaped silicone ring 204. The silicone strip will be snapped into the strip groove, facilitating alignment by workers and preventing misalignment of adjacent combination frames 203.

[0020] The fixing mechanism 3 includes fixing plates 301 located above and below adjacent air duct frames 1. Each fixing plate 301 has a slot 302 on its adjacent end face, and the combined frame 203 is located within the slot 302. When the adjacent air duct frame 1 is lifted, the combined frame 203 is inserted between the two fixing plates 301 on the roof. The fixing plates 301 move upwards, causing the combined frame 203 to enter the slot 302 of the upper fixing plate 301. Due to the inclined inner wall of the slot 302, the movement of the two fixing plates 301 pushes the two combined frames 203 closer together, ultimately causing the irregularly shaped silicone rings 204 on the adjacent combined frames 203 to fit tightly, achieving a good sealing effect. This excellent sealing performance prevents airflow leakage within the air duct, ensuring the ventilation efficiency of the air duct system, reducing energy consumption, and avoiding the impact on the surrounding environment caused by airflow leakage. Simultaneously, the two fixing plates 301 clamp the combined frame 203 to prevent the connection position of the adjacent air duct frames 1 from shaking.

[0021] Mounting bracket 4 is fixedly connected to the upper fixing plate 301. A fixing strip 303 is fixedly connected to one side of the upper fixing plate 301. A sliding groove 304 is formed on the lower part of the fixing strip 303 near the end face of the fixing plate 301. A first threaded rod 305 is rotatably connected inside the sliding groove 304, and the lower end of the first threaded rod 305 extends out of the sliding groove 304. A sliding block 307 is fixedly connected to one side of the lower fixing plate 301. The sliding block 307 extends into the sliding groove 304, and the sliding groove 304 is rotatably connected to the first threaded rod 305 by threads. A rotating block 308 is rotatably connected to the other side of the lower fixing plate 301. The rotating block 308 is internally connected to a second threaded rod 309 via a threaded connection. One end of the second threaded rod 309 is fixedly connected to an extension rod 310, and the other end of the extension rod 310 is rotatably connected to a positioning block 311. A limit block 312 is fixedly connected to the other side of the upper fixed plate 301. A positioning groove 313 is formed on the upper end surface of the limit block 312. The lower ends of both the second threaded rod 309 and the first threaded rod 305 are fixedly connected to knobs 306. The second threaded rod 309 and the extension rod 310 block one side of the two fixed plates 301, effectively preventing the combined frame 203 in the slot 302 from sliding out, thus providing a stable fixing method for the duct frame 1. During the operation of the duct system, even when subjected to external forces such as airflow impact, the duct frame 1 can remain stable and will not shift or fall off, ensuring the safety and reliability of the duct system.

[0022] Rotating the knob 306 causes the lower fixing plate 301 to move upward via the first threaded rod 305 and the second threaded rod 309, allowing the combined frame 203 to enter the slot 302 of the upper fixing plate 301. The sealing installation operation between the air duct frames 1 is simple and direct, enabling quick positioning and installation of the air duct frames 1 without the need for complex positioning tools and operations, thus saving installation time.

[0023] Working principle: First, the staff installs multiple mounting brackets 4 located on the upper fixed plate 301 onto the roof. Then, the staff installs a pair of connecting frames 201 onto both ends of the air duct frame 1. After the installation of multiple air duct frames 1 is completed, the combination frames 203 on two adjacent air duct frames 1 are aligned together. The irregular silicone rings 204 on the two combination frames 203 are attached together. One side of the irregular silicone ring 204 has a silicone strip on its contact end face, and the other side of the irregular silicone ring 204 has a strip groove on its contact end face. The silicone strip will be inserted into the strip groove, which makes it easy for the staff to align and prevents the adjacent combination frames 203 from being misaligned.

[0024] The staff lifted the adjacent air duct frame 1 and inserted the combined frame 203 on the adjacent air duct frame 1 between the two fixed plates 301 on the roof. The combined frame 203 was placed into the slot 302 on the lower fixed plate 301. The rotating block 308 on one side of the lower fixed plate 301 was rotated. The rotation of the rotating block 308 caused the second threaded rod 309, the extension rod 310 and the positioning block 311 to rotate synchronously. The downward-facing second threaded rod 309, the extension rod 310 and the positioning block 311 were flipped 180 degrees, and the positioning block 311 was inserted into the positioning groove 313 of the upper limit block 312 on the upper fixed plate 301. The second threaded rod 309 and the extension rod 310 blocked one side of the two fixed plates 301 to prevent the combined frame 203 in the slot 302 from sliding out.

[0025] Simultaneously rotating the knobs 306 on the second threaded rod 309 and the first threaded rod 305 causes the two knobs 306 to rotate, driving the second threaded rod 309 and the first threaded rod 305. The rotation of the first threaded rod 305 causes the sliding block 307 to move, and the movement of the sliding block 307 causes one end of the lower fixed plate 301 to move upward. The rotation of the second threaded rod 309 causes the rotating block 308 to move, and the movement of the rotating block 308 causes the other end of the lower fixed plate 301 to move upward. The lower fixed plate 301 and the combination frame 203 move towards the upper fixed plate 301. The combination frame 203 enters the slot 302 of the upper fixed plate 301. Since the inner wall of the slot 302 is inclined, when the two fixed plates 301 approach each other, the inner wall of the slot 302 pushes the two combination frames 203 closer together. The moving frame 202 on the combination frame 203 moves within the connecting frame 201. The irregularly shaped silicone rings 204 on the two combination frames 203 are pressed tightly together to achieve a good sealing effect.

[0026] For later disassembly and maintenance, it is only necessary to adjust the fixing plates 301 on both sides of a certain air duct frame 1. By turning the knob 306, the first threaded rod 305 and the second threaded rod 309 rotate, causing the two fixing plates 301 to move away, and the adjacent combination frame 203 can be separated. Then, the upward-facing second threaded rod 309, extension rod 310 and positioning block 311 are rotated 180 degrees, and the staff can take out a certain air duct frame 1 for maintenance.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
