Description

Technical Field

[0001] This utility model relates to the field of refrigerator structure technology, and in particular to a refrigerator air duct assembly and a refrigerator. Background Technology

[0002] Refrigerators are an indispensable appliance in modern homes, and their internal air circulation and purification effects directly affect the freshness of food and the user's health experience.

[0003] Traditional refrigerators typically have their filtration or deodorizing modules permanently integrated into the air duct system. This integrated design makes subsequent maintenance and cleaning extremely inconvenient. Users find it difficult to clean or replace the filter, and after long-term use, not only does the purification effect decrease, but the accumulated dirt may also become a source of secondary pollution. In addition, traditional air duct components are often fixed to the refrigerator body with screws, making disassembly and installation cumbersome when cleaning or repairing the inside of the air duct and functional modules. To solve the above problems, this utility model provides an air duct component for a refrigerator and a refrigerator. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a refrigerator air duct assembly and a refrigerator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A refrigerator air duct assembly and a refrigerator, comprising an air duct body, an mounting plate fixedly connected to the front of the air duct body, two slots opened at the upper end of the air duct body, two U-shaped mounting frames fixedly connected inside the air duct body, the two U-shaped mounting frames respectively connected to the two slots, insert plates inserted into the interior of each of the two slots, and sealing frames adapted to the U-shaped mounting frames fixedly connected to the lower ends of each of the two insert plates, a filter screen disposed inside one of the sealing frames, an activated carbon layer disposed inside the other sealing frame, and circular slots opened on both sides of the mounting plate.

[0006] As a further improvement of this utility model, a storage groove is provided at the upper end of the sealing frame, and a first handle is fixedly connected inside the storage groove.

[0007] As a further improvement of this utility model, several air inlet slots are provided on both sides of the front of the mounting plate, and a second handle is fixedly connected to the upper end of the front of the mounting plate.

[0008] As a further improvement of this utility model, the refrigerator also includes a refrigerator body, and a base is fixedly connected to the lower end of the refrigerator body. The front of the base is provided with a mounting groove that is adapted to the mounting plate. The inside of the mounting groove is provided with an air duct groove that is adapted to the air duct body. Sliding grooves are provided on both sides of the mounting groove, and snap-fit ​​components are fixedly connected inside the two sliding grooves.

[0009] As a further improvement of this utility model, the snap-fit ​​assembly includes a connecting block fixedly connected inside the slide groove, a return spring fixedly connected to one side of the connecting block, and a spherical snap-fit ​​block adapted to the circular snap-fit ​​groove fixedly connected to the other end of the return spring.

[0010] As a further improvement of this utility model, a sleeve rod is fixedly connected to the middle end of the connecting block, and a limit rod is movably connected inside the sleeve rod. The other end of the limit rod is fixedly connected to a spherical locking block, and both the sleeve rod and the limit rod are located inside the return spring.

[0011] The beneficial effects of this utility model are: By setting slots and insert plates on the main body of the air duct, the sealing frame containing the filter and activated carbon layer can be easily inserted and removed. When the filter accumulates too much dust due to long-term use and affects the filtration effect, or when the activated carbon layer is saturated and needs to be replaced, the insert plate along with the sealing frame can be pulled out of the slot by simply using the first handle in the storage groove at the top of the sealing frame to replace the filter or activated carbon layer. This simplifies the maintenance process, reduces the difficulty of maintenance, and improves the convenience and overall experience of using the refrigerator.

[0012] By incorporating snap-fit ​​components, the refrigerator base has snap-fit ​​components on both sides of the mounting slot that mate with the circular slots on both sides of the air duct assembly mounting plate. During installation, the mounting plate is inserted into the mounting slot, and the mounting plate presses against the spherical locking block, causing it to compress the return spring and move into the groove. When the circular slot moves to the corresponding position, the return spring resets and pushes the spherical locking block into the circular slot, achieving quick snap-fit ​​fixation. For disassembly, the spherical locking block is disengaged from the circular slot by pulling the second handle on the mounting plate. This design is not only simple to operate, saving time and effort, but also provides a stable snap-fit ​​structure that ensures the air duct assembly will not loosen during use, improving the product's practicality and reliability.

[0013] By incorporating a filter and an activated carbon layer, air entering the refrigerator passes through both layers sequentially. The filter effectively intercepts larger particles such as dust and hair, preventing them from entering the refrigerator and attaching to food, thus affecting food hygiene. The activated carbon layer, with its powerful adsorption capacity, further adsorbs odor molecules, bacteria, and other tiny harmful substances from the air. The two work together to purify the air entering the refrigerator in multiple stages, improving the air quality inside and effectively extending the shelf life of food. Attached Figure Description

[0020] In this utility model, the upper end of the sealing frame 6 is provided with a storage groove. The storage groove can store the first handle 10 when it is not in use, so as to avoid the handle being exposed and occupying space or affecting the assembly of other parts. At the same time, it can protect the first handle 10 from damage. The first handle 10 is fixedly connected inside the storage groove. Several air inlet slots 11 are provided on both sides of the front of the mounting plate 2. The air inlet slots 11 provide a channel for airflow to enter the air duct body 1. The setting of multiple air inlet slots 11 can ensure the uniformity of air intake and improve the airflow efficiency. The upper end of the front of the mounting plate 2 is fixedly connected with a second handle 12. The second handle 12 provides a convenient force point for the overall disassembly and assembly of the air duct assembly, making it convenient for users to quickly operate the separation or assembly of the air duct assembly and the refrigerator body 13.

[0021] The refrigerator also includes a refrigerator body 13, with a base 14 fixedly connected to the lower end of the refrigerator body 13. The front of the base 14 has a mounting groove 15 that matches the mounting plate 2. The mounting groove 15 provides precise installation positioning for the mounting plate 2, ensuring that the mounting plate 2 fits tightly with the base 14. Inside the mounting groove 15, there is an air duct groove 16 that matches the air duct body 1. The air duct groove 16 provides space for the air duct body 1, ensuring the accuracy of the position of the air duct body 1 after installation and ensuring normal airflow. Sliding grooves are provided on both sides of the mounting groove 15. A snap-fit ​​component is fixedly connected inside the two sliding grooves. The sliding grooves provide installation space for the snap-fit ​​component and guide the movement of the snap-fit ​​component.

[0022] The snap-fit ​​assembly includes a connecting block 17 fixedly connected inside the slide groove. A return spring 18 is fixedly connected to one side of the connecting block 17. The return spring 18 provides elastic force to realize the automatic pop-out and retraction reset of the spherical snap-fit ​​block 19. The other end of the return spring 18 is fixedly connected to a spherical snap-fit ​​block 19 that is adapted to the circular snap-fit ​​groove 9. The spherical snap-fit ​​block 19 and the circular snap-fit ​​groove 9 cooperate to achieve snap-fit ​​fixation, ensuring the connection reliability of the air duct assembly after installation. A sleeve rod 20 is fixedly connected to the middle end of the connecting block 17. A limit rod 21 is movably connected inside the sleeve rod 20. The other end of the limit rod 21 is fixedly connected to the spherical snap-fit ​​block 19. Both the sleeve rod 20 and the limit rod 21 are located inside the return spring 18. The limit rod 21 can move along the inside of the sleeve rod 20 and cooperate with the sleeve rod 20 to achieve guiding and limiting, which plays a protective role for the return spring 18, preventing the return spring 18 from shifting or twisting, and ensuring its elastic performance is stable.

[0023] In use, the mounting plate 2 is fixed to the front of the duct body 1. Two slots 3 are opened at the upper end of the duct body 1, and two U-shaped mounting frames 4 connected to the slots 3 are fixed inside. The insert plate 5 with a sealing frame 6 that matches the U-shaped mounting frame 4 is inserted into the slot 3. One of the sealing frames 6 has a filter screen 7 and the other has an activated carbon layer 8. Circular slots 9 are fixed on both sides of the mounting plate 2. At this time, the duct assembly is ready. During installation, the mounting plate 2 of the duct assembly is aligned with the mounting groove 15 of the base 14 and inserted. The mounting plate 2 presses the spherical locking block 19, and the spherical locking block 19 compresses the return spring 18 and moves into the slide groove. When the circular slot 9 moves to the position corresponding to the spherical slot 19, the reset spring 18 resets and pushes the spherical slot 19 into the circular slot 9 to achieve a snap-fit ​​fixation. At this time, the air duct body 1 is located in the air duct groove 16. Air enters from the air inlet grooves 11 on both sides of the front of the mounting plate 2, and enters the refrigerator after being filtered and purified by the sealing frame 6 with the filter screen 7 and activated carbon layer 8. When disassembly is required, the mounting plate 2 can be pulled by the second handle 12 at the upper front of the mounting plate 2 to make the spherical slot 19 disengage from the circular slot 9, thereby removing the air duct assembly. The filter screen 7 and activated carbon layer 8 can be replaced by pulling the insert plate 5 by the first handle 10 in the storage groove.
