Description

Technical Field

[0001] This utility model relates to the field of cabinet air conditioners, and in particular to a filter structure for the air inlet of a cabinet air conditioner. Background Technology

[0002] Floor-standing air conditioners are a type of split-system air conditioner, with their indoor units designed to stand on the floor. An air inlet is located on the rear frame of the indoor unit; air enters through this inlet, is then regulated for temperature, and finally blown forward.

[0003] Generally, air inlets are equipped with physical filtration methods such as coarse filters or filtration cartridges to purify the air. While coarse filters ensure efficient airflow at the inlet, they cannot remove large airborne particles, bacteria, or other contaminants. On the other hand, filtration cartridges, through physical filtration, chemical decomposition, or ionization technology, can remove large airborne particles, bacteria, and other contaminants, but at the cost of significantly reduced airflow efficiency, potentially even affecting the air conditioner's heat exchange performance. In other words, current floor-standing air conditioners often only offer one of two filtration options for the air inlet: a coarse filter or a filtration cartridge. This means that while ensuring efficient airflow, it's impossible to achieve both simultaneously. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cabinet air inlet filter structure that can take into account both air intake efficiency and large particle dust filtration effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cabinet air inlet filter structure, including an air conditioner rear frame arranged in a vertical direction, an air inlet provided on the air conditioner rear frame, the air inlet including a first air inlet and a second air inlet, the first air inlet being arranged above the second air inlet, a coarse filter component being provided in the first air inlet, and a purification component being provided in the second air inlet.

[0006] Furthermore, the purification component includes a purification filter element, which includes a purification core, an upper core support, and a lower core support. The upper core support and the lower core support are connected by snap-fit, and the purification core is fixedly disposed between the upper core support and the lower core support.

[0007] Furthermore, the edge of the second air inlet is provided with a sliding groove rib, and the support on the core body is provided with a sliding groove. The sliding groove slides into the sliding groove rib, and the extension direction of the sliding groove rib is consistent with the sliding insertion direction of the sliding groove.

[0008] Furthermore, the support on the core is provided with a support positioning hole, and the edge of the second air inlet is provided with a support positioning rib. The support positioning rib is set in the support positioning hole to realize the positioning of the support on the core.

[0009] Furthermore, the lower support of the core is equipped with a support spring clip, and the edge of the second air inlet is equipped with a filter spring clip. The support spring clip is inserted into the filter spring clip to fix the lower support of the core.

[0010] Furthermore, the purification component includes a purification bracket, with hooks and buckles on the bracket of the core body. The bracket of the core body is attached to the purification bracket by the hooks and buckles, and the purification bracket is attached to the rear frame of the air conditioner.

[0011] Furthermore, the purification component includes a support coarse filter, which is mounted on the purification support and positioned on the side of the purification core facing the outside.

[0012] Furthermore, the coarse filter assembly includes a coarse filter bracket and a coarse filter screen, with the coarse filter screen mounted on the coarse filter bracket and the coarse filter bracket snapped onto the rear frame of the air conditioner.

[0013] The beneficial effects of this utility model are as follows: 1. Large particulate dust layers indoors are generally distributed at a height close to the ground. This solution cleverly differentiates the functions of the filtration structure to address this distribution characteristic. The second air inlet is positioned closer to the ground, allowing the large particulate dust layers near the ground to be filtered by the purification components within the second air inlet, which prioritizes filtration of these large particles. To compensate for the reduced air intake efficiency, a first air inlet is positioned at a higher height, above the second air inlet, and contains a corresponding coarse filter component, thereby improving air intake efficiency. By combining different filtration functions with the distribution characteristics of large particulate dust layers indoors, both air intake efficiency and the filtration effect of large particulate dust layers are achieved. 2. The purification components can be quickly and conveniently assembled and disassembled through the sliding cooperation of the slide groove and slide groove ribs, the positioning cooperation of the bracket positioning ribs and bracket positioning holes, and the snap-fit ​​fixing cooperation between the bracket spring clips and the filter spring clips. This utility model is particularly suitable for the air intake filtration process of cabinet air conditioners. Attached Figure Description

[0018] The components in the diagram are marked as follows: Air conditioner rear frame 1, bracket positioning rib 11, filter snap 12, sliding groove rib 13, coarse filter assembly 2, coarse filter bracket 21, coarse filter 22, purification assembly 3, purification bracket 31, bracket coarse filter 32, purification filter element 33, bracket positioning hole 301, bracket snap 302, sliding groove 303, hook 4, buckle 5, purification core 331, core upper bracket 332, core lower bracket 333. Detailed Implementation

[0019] The utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 This illustration shows one embodiment of the air inlet filter structure for a cabinet air conditioner. The outer casing of the indoor unit of a cabinet air conditioner is generally composed of a front frame and a rear frame 1 that are fastened together. The air outlet is located on the front frame, and the air inlet is located on the rear frame 1. The indoor unit is vertically mounted on the floor. Figure 1 As shown, the rear frame 1 of the air conditioner is equipped with a coarse filter assembly 2 and a purification assembly 3 from top to bottom. Generally, large particles of dust in the room are concentrated in the area less than 1 meter above the ground, so the height of the purification assembly 3 can be set to less than 1 meter above the ground.

[0021] The coarse filter assembly 2 consists of a coarse filter bracket 21 and a coarse filter screen 22. The coarse filter screen 22 is a mesh-like filter screen that can filter out larger impurities, such as paper scraps, while ensuring air intake efficiency. The coarse filter screen 22 can be installed on the coarse filter bracket 21 using existing injection molding processes. A sliding groove rib 13 is provided at the edge of the first air inlet corresponding to the coarse filter assembly 2. The coarse filter bracket 21 is inserted into the first air inlet along the extension direction of the sliding groove rib 13, and then the coarse filter bracket 21 is fixed to the rear frame 1 of the air conditioner using conventional clips, thus fixing the coarse filter assembly 2 to the first air inlet.

[0022] Regarding the purification component 3, it consists of a purification support 31, a coarse filter 32, and a purification filter element 33. The purification filter element 33 consists of a purification core 331, an upper support 332, and a lower support 333. Figure 4 In the purification filter element 33 shown, the upper support 332 and the lower support 333 are connected by snap-fit ​​to form a frame that fixes the purification core 331. The purification core 331 is then fixedly installed between the upper support 332 and the lower support 333. The purification core 331 can be a completely paper core or a composite filter material consisting of activated carbon and HEPA (high-efficiency particulate air filter).

[0023] A sliding rib 13 is also provided at the edge of the second air inlet corresponding to the purification component 3. This sliding rib 13, like the one corresponding to the coarse filter component 2, is fixedly mounted on the rear frame 1 of the air conditioner. A sliding groove 303 is provided on the upper bracket 332 of the core. During actual installation, the sliding groove 303 and the sliding rib 13 are arranged in a one-to-one correspondence. The sliding groove 303 slides into the sliding rib 13, and the sliding rib 13 is positioned inside the sliding groove 303, thus limiting the sliding groove 303. Since the extending direction of the sliding rib 13 is consistent with the sliding engagement direction of the sliding groove 303, the sliding groove 303 and the sliding rib 13 will only slide relative to each other along the extending direction of the sliding rib 13.

[0024] like Figures 2 to 3 As shown, a bracket positioning rib 11 is provided on the edge of the second air inlet. The bracket positioning rib 11 is a structure that protrudes from the surface of the air conditioner rear frame 1. The protruding direction of the bracket positioning rib 11 is consistent with the extension direction of the aforementioned sliding groove rib 13. A bracket positioning hole 301 is provided on the upper bracket 332 of the core body corresponding to the bracket positioning rib 11. When the purification filter element 33 slides into the second air inlet along the extension direction of the sliding groove rib 13, the bracket positioning rib 11 is set in the bracket positioning hole 301, thereby realizing the positioning of the upper bracket 332 of the core body. Subsequently, the bracket spring clip 302 provided on the lower bracket 333 of the core body is inserted into the filter spring clip 12 provided on the edge of the second air inlet, thereby fixing the lower bracket 333 of the core body and the purification filter element 33.

[0025] Regarding the relationship between the purification bracket 31 and the bracket coarse filter 32, the bracket coarse filter 32 can be fixed to the purification bracket 31 using the existing injection molding process. The bracket coarse filter 32 is positioned on the outside side of the purification core 331 to perform preliminary filtration of the air about to enter the purification core 331. Figure 3 As shown, the upper support 332 of the core body is provided with hooks 4 and buckles 5. The upper support 332 of the core body is snapped onto the purification bracket 31 by the hooks 4 and buckles 5, thereby fixing the purification filter element 33 to the purification bracket 31. Finally, similar to the fixing method of the coarse filter bracket 21, the purification bracket 31 is fixed to the rear frame 1 of the air conditioner by conventional buckles, and finally the purification component 3 is fixedly set on the second air inlet.

[0026] In practical use, the purification component 3, positioned near the ground, filters out large dust particles distributed close to the ground. The coarse filter component 2, positioned above the purification component 3, ensures efficient air intake. This organic integration of the purification component 3 and the coarse filter component 2 achieves a balance between efficient air intake and effective filtration of large dust particles.
