Description

Technical Field

[0001] This utility model relates to the field of air conditioner filter technology, and more specifically, to an air conditioner indoor unit filter that is easy to disassemble. Background Technology

[0002] Air conditioners, as devices for regulating indoor temperature, humidity, and air quality, are widely used in homes, offices, and other places. During the operation of an air conditioner, the filter of the indoor unit plays an important role in filtering dust, hair, and other impurities from the air, effectively preventing these impurities from entering the air conditioner, protecting its internal components, and improving indoor air quality.

[0003] The existing mechanism has a complex structure, is inconvenient to install, and is not easy to fix the filter screen, which causes the filter screen to accumulate and loosen during use, thus affecting the filtration performance of the filter screen.

[0004] A search revealed that Chinese patent CN217209574U discloses a filter structure for a cabinet-type air conditioner indoor unit. In terms of installation, the filter is placed in a storage slot, and the mounting plate and base plate are double-clamped for support and fixation. A threaded rod connects the first and second connecting blocks. A knob is manually rotated to tighten the gap between the mounting plate and the base plate, and then a nut is used to secure it, preventing loosening and ensuring stability. This also avoids loosening and accumulation due to wind resistance, improving load-bearing capacity and filtration performance. For cleaning and maintenance, the surface-mounted dustproof coating, with its micro-nano structure, reduces dust adhesion and accumulation, improving performance. Simultaneously, the activated carbon coating on the dustproof coating's end can absorb odors, and the anti-oxidation coating can reduce oxidation reactions, extending the filter's lifespan. The overall structure is simple and easy to operate, facilitating both installation and cleaning, making it highly practical.

[0005] However, in actual use, the filter body can only be supported and fixed by the double clamping of the mounting plate and the base plate. The fastening mechanism is fixed with nuts after manually rotating the knob to tighten the gap between the mounting plate and the base plate. However, it takes a lot of time and effort to ensure that the gap between the mounting plate and the base plate is appropriate and tight. For personnel who are not familiar with the installation process, it may be difficult to accurately control the tightening degree of the nuts, which affects the installation efficiency and quality.

Multiple fixing plates are fixedly installed on both sides of the second connecting frame, and the surface of the fixing plates is provided with multiple threaded grooves. The L-shaped inserts are connected to the threaded grooves by bolts.

[0010] By adopting the above technical solution, the installation mechanism ensures a stable connection between the first and second connecting frames, guaranteeing reliable filter screen installation and ensuring the filtration effect of the air conditioner indoor unit. Furthermore, the L-shaped insert and the threaded groove are connected by bolts, facilitating disassembly and cleaning or replacement of the filter screen, reducing maintenance difficulty, enhancing the practicality and durability of the filter screen, extending its service life, and reducing maintenance costs.

[0011] As a further description of the above technical solution: the T-shaped fixing block is inserted into the fixing frame, one end of the L-shaped insert passes through the fixing plate and extends outward from the fixing plate, a fixing cover is hinged on one side of the first connecting frame, a sealing layer is fixedly provided on one side of the fixing cover, a connecting block is fixedly provided on one side of the sealing layer, and threaded openings are provided on the surfaces of the connecting block and the second connecting frame, and anti-loosening bolts are threaded into the internal threads of the threaded openings.

[0012] By adopting the above technical solution, the connection between the first connecting frame and the second connecting frame is tighter and the positioning is more precise, ensuring that the filter frame is installed firmly, improving the filtration effect, and facilitating disassembly and installation. This makes it easier to clean or replace the filter, reducing maintenance difficulty, effectively preventing dust and other impurities from entering the air conditioner, ensuring the cleanliness of the air conditioner's interior, and extending the service life of the air conditioner.

[0013] As a further description of the above technical solution: the filter frame is provided with a filtration mechanism inside, the filtration mechanism includes a fine filter frame inserted into the filter frame, the fine filter frame is provided with an adsorption layer inserted into the fine filter frame, both the fine filter frame and the filter frame are made of stainless steel, and the adsorption layer is an activated carbon layer.

[0014] The sealing layer is made of rubber, and its shape is adapted to the shape of the gap between the first connecting frame and the second connecting frame.

[0015] By adopting the above technical solution: the multi-layer structure filter frame is equipped with a fine filter frame and an adsorption layer, which can intercept impurities of different sizes. The activated carbon adsorption layer can effectively adsorb odors and harmful gases. Multiple filtration improves the air purification effect and improves indoor air quality. It not only ensures the filtration effect, but also facilitates installation, disassembly and maintenance, and enhances the overall performance of the filter.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1.

Furthermore, the L-shaped insert and the threaded groove on the fixing plate are matched and connected with bolts, which enhances the connection strength between the first connecting frame and the second connecting frame, ensuring that the filter frame will not easily loosen during use, improving the stability of the entire filter structure. Moreover, the fixing plate plays an auxiliary role in positioning and installation, enhancing the overall performance of the filter and extending its service life. The space formed by the first connecting frame and the second connecting frame facilitates the placement of the filter frame, providing an accurate installation position for the filter frame, ensuring the installation accuracy of the filter, and thus improving the filtration effect of the air conditioner indoor unit.

[0018] 2. By incorporating a filtration mechanism, compared to existing technologies, the sealing layer of the fixed cover is made of rubber, which fits the gaps perfectly, effectively preventing dust and other impurities from entering the air conditioner's interior. This ensures the cleanliness of the air conditioner's interior, improves operational stability, and extends its lifespan.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] The embodiments disclosed in this application are as follows: Figure 1-5 The air conditioner indoor unit filter shown includes a first connecting frame 1, a U-shaped connecting frame 2 fixedly provided on one side of the first connecting frame 1, a second connecting frame 3 inserted into one side of the U-shaped connecting frame 2, a filter frame 4 inserted between the first connecting frame 1 and the second connecting frame 3, and an installation mechanism provided between the first connecting frame 1 and the U-shaped connecting frame 2.

[0027] The installation mechanism includes T-shaped fixing blocks 5 fixedly installed on both sides of the first connecting frame 1, fixing frames 6 fixedly installed on both sides of the second connecting frame 3, multiple slots opened on the surface of the fixing frames 6, L-shaped inserts 7 inserted into the slots, multiple fixing plates 8 fixedly installed on both sides of the second connecting frame 3, multiple threaded grooves 9 opened on the surface of the fixing plates 8, and the L-shaped inserts 7 and the threaded grooves 9 are connected by bolts.

[0028] Simultaneously, the T-shaped fixing blocks 5 fixed on both sides of the first connecting frame 1 are inserted into the fixing frames 6 fixed on both sides of the second connecting frame 3, thus initially positioning the first connecting frame 1 and the second connecting frame 3 to facilitate subsequent installation operations.

[0029] Meanwhile, the fixing plates 8 on both sides of the second connecting frame 3 serve as auxiliary positioning and installation. The surface of the fixing plate 8 has multiple threaded grooves 9, which are used in conjunction with the L-shaped insert 7. The L-shaped insert 7 is inserted into the appropriate slots on the surface of the fixing plate 8 and the fixing frame 6, and then bolts are used to connect the L-shaped insert 7 to the threaded grooves 9, thereby achieving a stable connection between the first connecting frame 1 and the second connecting frame 3, and then the filter frame 4 is inserted between the first connecting frame 1 and the second connecting frame 3.

[0030] Reference Figure 2-3 As shown, the T-shaped fixing block 5 is inserted into the fixing frame 6, one end of the L-shaped insert 7 passes through the fixing plate 8 and extends outward from the fixing plate 8, a fixing cover 10 is hinged on one side of the first connecting frame 1, a sealing layer 11 is fixedly installed on one side of the fixing cover 10, a connecting block 12 is fixedly installed on one side of the sealing layer 11, and threaded openings are opened on the surfaces of the connecting block 12 and the second connecting frame 3, and anti-loosening bolts 13 are threaded inside the threaded openings.

[0031] Because a fixed cover 10 is hinged on one side of the first connecting frame 1, after the filter frame 4 is installed, the fixed cover 10 is placed on the first connecting frame 1. The sealing layer 11 fixed on one side of the fixed cover 10 is made of rubber material, and its shape is adapted to the shape of the gap between the first connecting frame 1 and the second connecting frame 3. This can effectively prevent dust and other impurities from entering the air conditioner from the gap and play a sealing role.

[0032] The connecting block 12, which is fixedly installed on one side of the sealing layer 11, and the second connecting frame 3 both have threaded openings on their surfaces. The connecting block 12 and the second connecting frame 3 are connected by anti-loosening bolts 13 to further ensure the firmness of the installation of the fixed cover 10 and at the same time ensure the sealing effect.

[0033] Reference Figure 4-5 As shown, the filter frame 4 is provided with a filter mechanism inside. The filter mechanism includes a fine filter frame 14 inserted into the filter frame 4. An adsorption layer 15 is inserted into the fine filter frame 14. Both the fine filter frame 14 and the filter frame 4 are made of stainless steel. The adsorption layer 15 is an activated carbon layer.

[0034] The sealing layer 11 is made of rubber, and the shape of the sealing layer 11 is adapted to the shape of the gap between the first connecting frame 1 and the second connecting frame 3;

[0035] The filter frame 4 has a filter mechanism inside, in which a fine filter frame 14 is inserted inside the filter frame 4 and an adsorption layer 15 is inserted inside the fine filter frame 14. When air flows through the filter, it first passes through the filter frame 4, which is a coarse filter frame that can intercept larger particles of dust, hair and other impurities in the air. The fine filter frame 14 is made of stainless steel and can intercept smaller particles of dust and impurities in the air, playing a further preliminary filtration role.

[0036] After filtration, the air continues to pass through the adsorption layer 15, which is an activated carbon layer. Activated carbon has a rich pore structure and a large specific surface area, which can adsorb odors and harmful gases in the air, thereby achieving further purification of the air and improving indoor air quality.

[0037] When the filter frame 4 needs to be cleaned or replaced, first unscrew the anti-loosening bolt 13, open the fixing cover 10, and pull the filter frame 4 out from between the first connecting frame 1 and the second connecting frame 3. Then, remove the adsorption layer 15 from the fine filter frame 14 for replacement, and remove the fine filter frame 14 from the filter frame 4 for separate cleaning or replacement.

[0038] Working principle of this utility model:

[0039] This utility model is a filter screen for an air conditioner indoor unit that is easy to disassemble. When the device is in use, since a U-shaped connecting frame 2 is fixedly installed on one side of the first connecting frame 1, the second connecting frame 3 is inserted into one side of the U-shaped connecting frame 2. At this time, the filter screen frame 4 is placed between the first connecting frame 1 and the second connecting frame 3.

[0040] Simultaneously, the T-shaped fixing blocks 5 fixed on both sides of the first connecting frame 1 are inserted into the fixing frames 6 fixed on both sides of the second connecting frame 3, thus initially positioning the first connecting frame 1 and the second connecting frame 3 to facilitate subsequent installation operations.

[0041] Meanwhile, the fixing plates 8 on both sides of the second connecting frame 3 serve as auxiliary positioning and installation. The surface of the fixing plate 8 has multiple threaded grooves 9, which are used in conjunction with the L-shaped insert 7. The L-shaped insert 7 is inserted into the appropriate slots on the surface of the fixing plate 8 and the fixing frame 6, and then bolts are used to connect the L-shaped insert 7 to the threaded grooves 9, thereby achieving a stable connection between the first connecting frame 1 and the second connecting frame 3, and then the filter screen frame 4 is inserted between the first connecting frame 1 and the second connecting frame 3.

[0042] Because a fixed cover 10 is hinged on one side of the first connecting frame 1, after the filter frame 4 is installed, the fixed cover 10 is placed on the first connecting frame 1. The sealing layer 11 fixed on one side of the fixed cover 10 is made of rubber material, and its shape is adapted to the shape of the gap between the first connecting frame 1 and the second connecting frame 3. This can effectively prevent dust and other impurities from entering the air conditioner from the gap and play a sealing role.

[0043] The connecting block 12, which is fixedly installed on one side of the sealing layer 11, and the second connecting frame 3 both have threaded openings on their surfaces. The connecting block 12 and the second connecting frame 3 are connected by anti-loosening bolts 13 to further ensure the firmness of the installation of the fixed cover 10 and at the same time ensure the sealing effect.

[0044] The filter frame 4 has a filter mechanism inside, in which a fine filter frame 14 is inserted inside the filter frame 4 and an adsorption layer 15 is inserted inside the fine filter frame 14. When air flows through the filter, it first passes through the filter frame 4, which is a coarse filter frame that can intercept larger particles of dust, hair and other impurities in the air. The fine filter frame 14 is made of stainless steel and can intercept smaller particles of dust and impurities in the air, playing a further preliminary filtration role.

[0045] After filtration, the air continues to pass through the adsorption layer 15, which is an activated carbon layer. Activated carbon has a rich pore structure and a large specific surface area, which can adsorb odors and harmful gases in the air, thereby achieving further purification of the air and improving indoor air quality.

[0046] When the filter frame 4 needs to be cleaned or replaced, first unscrew the anti-loosening bolt 13, open the fixing cover 10, and pull the filter frame 4 out from between the first connecting frame 1 and the second connecting frame 3. Then, remove the adsorption layer 15 from the fine filter frame 14 for replacement, and remove the fine filter frame 14 from the filter frame 4 for separate cleaning or replacement.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
