Description

Technical Field

[0001] This utility model relates to the technical field of fresh air equipment, and in particular to a fresh air integrated machine with a filtration device. Background Technology

[0002] As people's demands for indoor air quality continue to increase, integrated air conditioning units with both fresh air and air conditioning functions have become widely used. These integrated units typically combine a fresh air module, an air conditioning module, and an air filtration system, aiming to provide a clean and temperature-appropriate indoor environment. However, the filter element in the filtration system is a consumable and requires regular replacement and maintenance. Therefore, the ease and reliability of filter replacement have become key factors in evaluating the rationality of the integrated unit's design.

[0003] However, some existing integrated fresh air conditioning units, such as the energy-saving, spray-type integrated fresh air conditioning unit with dual winter and summer operating conditions disclosed in document CN114935187A, although they arrange coarse filters in the supply and return air paths and mention in their abstract that "the filter can be replaced by opening the front panel," attempting to solve the filter replacement problem, still have room for optimization in their filter maintenance structure. This solution only provides a simple notch or opening, lacking specialized guiding and limiting structures, which may cause the filter to get stuck, tilt, or interfere with internal precision components during replacement. Furthermore, the direction and method of filter removal may not be standardized or integrated enough, failing to fully utilize the characteristics of the housing structure, resulting in low replacement efficiency and potentially affecting the machine's internal sealing.

[0004] Therefore, existing filtration devices still suffer from drawbacks such as cumbersome operation, easy damage to internal components, and low replacement efficiency when replacing filter elements. There is an urgent market need for a filtration device with a more rational structure, more convenient operation, and the ability to ensure stable sliding of the filter element in and out, in order to improve the maintenance efficiency and reliability of integrated fresh air systems. Utility Model Content

[0005] Therefore, it is necessary to provide a fresh air unit with a filtration device to address the above problems.

[0006] This application provides a fresh air unit with a filtration device, including a fresh air module and an outdoor unit module. The fresh air module includes a top cover and a side panel, which together with a partition form a housing structure. The housing has an air inlet. The filtration device includes a filter element and a guide rail. The guide rail is disposed within the housing structure, enabling the filter element to filter the air entering through the air inlet. The filter element slides along the guide rail until it detaches from the housing structure, and the sliding direction is the air outlet direction of the outdoor unit module.

[0007] Optionally, the side plate of the housing structure has an opening suitable for the filter element to slide out, and the filter element slides out in the guide rail towards the front panel of the frame. The panel has a filter element replacement port that is compatible with the filter element cover.

[0008] Optionally, the opening is provided with a detachable filter cover.

[0009] Optionally, the guide rail includes a ground rail disposed on the partition, the ground rail including a pair of rails, the pair of rails and the partition together forming a groove suitable for the sliding of the filter element.

[0010] Optionally, the guide rail includes a top rail disposed on the top cover, the top rail including a pair of rails disposed thereon, the pair of rails and the top cover together forming a groove suitable for the sliding of the filter element.

[0011] Optionally, the rail has an L-shaped cross-section, and the openings of a pair of rails are opposite to or away from each other.

[0012] Optionally, the filter element is disposed between the air inlet and the evaporator.

[0013] Optionally, the air inlet, filter element, and evaporator are collinear.

[0014] Optionally, the width of the filter element is not less than the width of the evaporator.

[0015] Optionally, the filter element is disposed inside the filter box, the filter box is slidably connected to the guide rail, and the cover plate is connected to the side wall of the filter box.

[0016] Compared with the prior art, the technical solution provided in this application has the following advantages: The aforementioned integrated fresh air unit with a filtration device achieves integrated unit design by setting up a housing structure that includes a fresh air module and an outdoor unit module. The guide rail is set inside the housing structure, which not only serves to support and limit the filter element, ensuring that the filter element can stand stably on the air intake path to effectively filter the air, but more importantly, the direction in which the filter element slides along the guide rail is the air outlet direction of the outdoor unit module. By utilizing the internal space layout of the unit, the filter element removal path is aligned with the airflow direction of the outdoor unit's heat dissipation or exhaust, avoiding interference with other core components inside the housing when the filter element is pulled out. This provides users with the possibility and convenience of performing filter element maintenance in specific installation environments (such as when the equipment is close to the wall or installed in a narrow space).

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] See Figure 1 and Figure 2 An embodiment of this utility model provides a fresh air integrated unit with a filtration device, including a fresh air module 100 and an outdoor unit module 200. The fresh air module 100 includes a top cover 110 and a side plate 120. The top cover 110, the side plate 120 and the partition together form a shell structure. An air inlet 130 is provided on the shell. The filtration device includes a filter element 140 and a guide rail 150. The guide rail 150 is disposed inside the shell structure, so that the filter element 140 can filter the air entering through the air inlet 130. The filter element 140 slides along the guide rail 150 until it is detached from the shell structure, and the sliding direction is the air outlet direction of the outdoor unit module 200.

[0021] This embodiment achieves integrated unit design by setting up a housing structure that includes a fresh air module 100 and an outdoor unit module 200. The guide rail 150 is set inside the housing structure, which not only serves to support and limit the filter element 140, ensuring that the filter element 140 can stand stably on the air intake path to effectively filter the air, but more importantly, the direction in which the filter element 140 slides along the guide rail 150 is the air outlet direction of the outdoor unit module 200. By utilizing the internal space layout of the unit, the disassembly path of the filter element 140 is aligned with the airflow direction of the outdoor unit's heat dissipation or exhaust, avoiding interference with other core components inside the housing when the filter element 140 is pulled out. This provides users with the possibility and convenience of maintaining the filter element 140 in specific installation environments (such as when the equipment is close to the wall or installed in a narrow space).

[0022] Inside the integrated unit, the outdoor unit module 200 typically contains high-heat or bulky components such as a compressor and condenser fan, and its air outlet channel is a necessary heat dissipation path. By setting the removal and installation path of the filter element 140 to be consistent with this air outlet direction, the need to create a separate maintenance channel for the removal and installation of the filter element 140, thus avoiding increasing the unit's size, is avoided. Furthermore, this sliding release method, combined with the rigid support of the guide rail 150, prevents the filter element 140 from drooping and touching the electrical components or pipes below when it is pulled out, effectively preventing the risk of accidental injury during maintenance and greatly improving the compactness of the unit's internal structure and the safety of maintenance.

[0023] See Figure 2 and Figure 3 In one embodiment, the side plate 120 of the housing structure has an opening 160 suitable for the filter element 140 to slide out. The filter element 140 slides out in the guide rail 150 towards the front panel of the frame. The panel has a filter element 140 replacement port that is adapted to the filter element 140 cover plate.

[0024] Building upon the aforementioned embodiments, this embodiment further optimizes the installation and removal experience of the filter element 140. It defines an opening 160 on the side panel 120 of the housing for the filter element 140 to slide out, clearly indicating that the sliding direction is towards the front panel of the frame. A replacement port adapted to the filter element 140 cover is provided on the panel, enabling front-end maintenance. Users do not need to disassemble the entire machine casing, move the machine body, or go around to the back of the machine; they can simply pull out the filter element 140 through the replacement port on the front side panel of the frame. This design greatly improves the convenience of replacing consumables, especially in scenarios where the machine is embedded or where side space is limited.

[0025] In practical applications, the left, right, and rear sides of an integrated fresh air unit are often flush against walls or obstacles, creating what are known as maintenance blind spots. Using traditional side-pull or rear-pull methods, users must remove the entire unit to replace the filter 140, which is extremely inconvenient. This invention utilizes internal guide rails 150 to forcefully guide the movement of the filter 140 to the only always-open operating surface of the device—the front panel. This front-drawer design allows users to complete all maintenance actions while facing the front of the machine, completely breaking down the limitations imposed by the installation environment on equipment maintenance. This provides the necessary technical prerequisite for fully embedded installation of the unit, significantly enhancing the product's market competitiveness and installation flexibility.

[0026] See Figure 2 and Figure 3 In one embodiment, the opening 160 is provided with a detachably connected filter element 140 cover. The filter element 140 cover seals the opening 160 on the side plate 120, preventing unfiltered air from directly entering the machine body through the opening 160 (i.e., preventing air leakage), ensuring the airtightness and filtration efficiency of the air duct; at the same time, the presence of the cover maintains the integrity of the machine body's appearance and can also fix the position of the filter element 140 to prevent it from shifting during machine operation vibration.

[0027] See Figure 3 and Figure 4 In one embodiment, the guide rail 150 includes a ground rail 151 disposed on the partition, the ground rail 151 including a pair of rails disposed thereon, the pair of rails together with the partition forming a groove suitable for sliding of the filter element 140.

[0028] This embodiment utilizes an existing structure to achieve stable support for the filter element 140. The limiting guide rail 150 includes a ground rail 151 mounted on the partition, and a pair of rails together with the partition form a sliding groove. The partition typically serves to separate modules or guide airflow in integrated fresh air systems, possessing a certain strength and rigidity. Placing the ground rail 151 on it fully utilizes the support surface of the partition, eliminating the need for additional complex support structures, thereby simplifying mold design and assembly processes. As the main load-bearing component, the ground rail 151 provides solid bottom support and precise guiding limits for the insertion and removal of the filter element 140, preventing the filter element 140 from tilting or derailing due to gravity or friction during sliding.

[0029] See Figure 3 and Figure 4 In one embodiment, the guide rail 150 includes a top rail 152 disposed on the top cover 110. The top rail 152 includes a pair of rails disposed together with the top cover 110 to form a groove suitable for sliding of the filter element 140.

[0030] This embodiment enhances the smoothness and anti-shaking performance of the filter element 140 during sliding, complementing the previous embodiment. In this embodiment, the guide rail 150 includes a top rail 152 disposed on the top cover 110. The top rail 152, consisting of a pair of rails forming a groove with the top cover 110, provides a precise limit above the filter element 140. The top rail 152 works in conjunction with the ground rail 151 to form a double-guided structure, effectively restraining the vertical sway of the filter element 140, especially when the filter element 140 is wide, heavy, or may vibrate during machine operation. This ensures that the filter element 140 always remains on the designed airflow path, avoiding noise or structural damage caused by swaying. It should be noted that both the ground rail 151 and the top rail 152 can be used independently to achieve the sliding and fixing effect of the filter element 140; this embodiment does not specifically limit this.

[0031] See Figure 4 In one embodiment, the rails have an L-shaped cross-section, with the openings 160 of a pair of rails facing each other or away from each other. This embodiment shows that the rails have an L-shaped cross-section, and that the openings 160 of a pair of rails can be facing each other or away from each other. The L-shaped cross-section is characterized by its simple structure and ease of processing (such as extrusion molding or sheet metal bending), providing sufficient rigidity to support and guide the filter element 140 with less material. Whether the openings 160 face each other to form a clamping groove or the openings 160 face away to form an externally supported slide, the L-shaped structure provides a clear sliding path for the filter element 140 and effectively prevents displacement under lateral forces, ensuring the reliability and smoothness of filter element 140 replacement operations.

[0032] See Figure 3 In one embodiment, filter element 140 is disposed between air inlet 130 and evaporator 180. Evaporator 180 is a key component for heat exchange in the integrated fresh air unit, and its surface fins are very fine, easily contaminated and clogged by dust, lint, and other impurities in the air. Placing filter element 140 upstream of evaporator 180 ensures that all air entering the unit is purified by filter element 140 first. This significantly reduces the chance of dust deposition on the surface of evaporator 180, thereby keeping evaporator 180 clean, maintaining its high heat exchange efficiency, extending the service life of evaporator 180 and even the entire unit, and reducing the frequency of maintenance and cleaning.

[0033] See Figure 3In one embodiment, the air inlet 130, filter element 140, and evaporator 180 are collinear. In this embodiment, the air inlet 130, filter element 140, and evaporator 180 are collinear (arranged in a straight line). This linear airflow design avoids the need for significant turns or detours when air enters and passes through the filter element 140 and evaporator 180. The shorter and straighter the airflow path, the lower the fluid resistance (pressure loss). Reduced airflow resistance directly reduces the energy consumed by the fan to propel the air, improving the energy efficiency ratio. Simultaneously, the straight flow effectively avoids regenerated noise caused by eddies and turbulence at sharp turns, making the integrated fresh air unit quieter during operation.

[0034] See Figure 3 In one embodiment, the width of filter element 140 is not less than the width of evaporator 180. This embodiment ensures comprehensive filtration and prevents airflow short-circuiting. In air filtration systems, it is common for airflow to bypass the filter medium along the edge of filter element 140 and directly enter downstream components, i.e., bypassing or airflow short-circuiting. By ensuring that the effective filtration width of filter element 140 is at least equal to the width of the air-receiving surface of evaporator 180, the airflow cross-section in front of evaporator 180 can be completely covered geometrically. This ensures that all air entering evaporator 180 must pass through the effective filtration area of ​​filter element 140, maximizing filtration efficiency and further enhancing the protection of evaporator 180.

[0035] This embodiment constructs a fully covered interception network by specifying the coverage width of the filter element 140 (typically slightly larger than the windward side of the evaporator 180 in engineering practice), forcing all airflows towards the evaporator 180 to pass through the high-resistance filter medium. This not only achieves 100% filtration coverage but also helps to rectify and evenly distribute the airflow before entering the evaporator 180, avoiding problems such as condensate splashing or uneven heat exchange caused by excessively high local wind speeds in the evaporator 180.

[0036] See Figure 5 In one embodiment, the filter element 140 is disposed within a filter box, the filter box is slidably connected to the guide rail 150, and the cover is connected to the side wall of the filter box. This embodiment further refines the structure of the filter element 140, placing the filter element 140 within a filter box, with the filter box slidably connected to the guide rail 150, and the cover directly connected to the side wall of the filter box. This feature integrates the soft or loose filter element 140 material into a rigid drawer-type assembly. On the one hand, the rigid filter box bears the sliding friction, protecting the fragile filter element 140 material; on the other hand, the integrated connection between the cover and the filter box allows the user to simultaneously pull out the entire filter box when pulling the cover, achieving a convenient pull-out operation, while also simplifying the fitting difficulty of the sealing structure, making the replacement process more intuitive and efficient.

[0037] More importantly, the cover is directly fixed to the side wall of the filter box, making it not only an aesthetic component but also the handle and positioning reference for the filter box. When the user pushes the cover in until it is flush with the panel, the filter box is precisely positioned, and the sealing ring on the back of the cover simultaneously presses against the opening 160 of the housing. This design eliminates the user's doubts about whether the filter element 140 is pushed in correctly. The intuitive feedback that the seal is complete when the cover closes ensures the ultimate airtightness of the air duct, preventing whistling noises and efficiency losses caused by air leakage.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
