Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a segmented duct air conditioner structure. Background Technology

[0002] In large spaces such as industrial plants and production workshops, ducted air conditioners are commonly used for ventilation and temperature control. Most existing ducted air conditioners use a fixed air supply structure. If a direct-blowing type is used, although it can quickly achieve local airflow circulation, the air supply direction is singular, which can easily lead to uneven temperature distribution in the space, and the temperature control effect is poor in areas far from the air outlet. If a duct connection type is used, although it can achieve multi-zone air supply, once the duct is installed, it cannot be flexibly switched back to direct-blowing mode. When it is necessary to temporarily enhance air supply or rapidly heat up specific workstations, the equipment is not adaptable enough and cannot meet the diverse air supply needs in large space scenarios.

The threaded hole is disposed on the side wall of the first housing, and the mounting hole is disposed on the jet vent assembly and corresponds to the threaded hole. The screw passes through the mounting hole and is threadedly connected to the threaded hole, so that the jet vent assembly is fixed relative to the first housing.

[0006] As a further improvement to the above technical solution, the connecting assembly includes a locking head and a limiting box. The locking head is fixedly connected to the outer wall of the jet vent assembly and has a locking groove. The limiting box is fixedly connected to the outer wall of the first housing. The inner side of the limiting box has a spring, a locking block, and a sliding groove for the locking head to be inserted. The middle part of the locking block is hinged to the limiting box. One end of the locking block has a locking part that cooperates with the locking groove. The other end of the locking block is fixedly connected to the spring. The other end of the spring is fixedly connected to the limiting box. The spring has a tendency to push the end of the locking block near the sliding groove toward the sliding groove. The end of the locking block away from the sliding groove has a control block, which protrudes from the outer wall of the limiting box.

[0007] As a further improvement to the above technical solution, the jet vent assembly includes a second housing and a plurality of jet vent bodies, all of which are arranged side by side on the second housing and all of which are connected to the internal space of the second housing.

[0008] As a further improvement to the above technical solution, a filter assembly is also included. The filter assembly includes a filter plate, a slide groove, and a frame. The frame is disposed on the air inlet side of the first housing and covers the air inlet. The slide groove is disposed on the frame. One end of the filter plate is inserted into the slide groove and slidably connected to the slide groove. The other end of the filter plate is provided with a handle.

[0009] As a further improvement to the above technical solution, the air supply assembly includes an electric motor and a volute impeller driven by the electric motor, with the air inlet end of the volute impeller facing the air outlet end of the evaporator assembly and the air outlet end of the volute impeller facing the air outlet.

[0010] As a further improvement to the above technical solution, a diffuser box is also included. The diffuser box is detachably disposed at the air outlet of the first housing and located between the air outlet and the jet air outlet assembly. The diffuser box is provided with a plurality of slots evenly distributed on it to uniformly distribute the airflow and guide the airflow to the air inlet of the jet air outlet assembly.

[0011] As a further improvement to the above technical solution, the reserved interface includes a flange and a gasket surrounding the air outlet.

The detachable design of the jet air outlet assembly and connecting components, along with the reserved interface on the air outlet side of the first housing, allows for flexible switching between direct blowing mode and duct connection mode. When the jet air outlet assembly is installed, it can concentrate direct blowing on specific areas to meet needs such as temporary enhanced air supply and rapid heating. After disassembly, connecting to an external duct via the reserved interface enables uniform air supply to multiple areas, significantly improving the equipment's adaptability in large-space scenarios. The jet air outlet assembly effectively guides airflow, resulting in a wider and more uniform air supply range, reducing the problem of uneven temperature distribution within the space. Combined with the cooling, heating, and reheating functions of the evaporator assembly and electric heating assembly, it can more accurately control the outlet air temperature, improving the temperature regulation effect throughout the space. The jet air outlet assembly is detachable via the connecting components, requiring no complex tools or professional skills for installation and disassembly, and can be quickly disassembled and cleaned during routine maintenance. Duct connection also only requires connecting to the reserved interface, simplifying operation and reducing the time and labor costs of later equipment maintenance. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0020] In large spaces such as industrial plants and production workshops, ducted air conditioners are commonly used for ventilation and temperature control. Most existing ducted air conditioners use a fixed air supply structure. If a direct-blowing type is used, although it can quickly achieve local airflow circulation, the air supply direction is singular, which can easily lead to uneven temperature distribution in the space, and the temperature control effect is poor in areas far from the air outlet. If a duct connection type is used, although it can achieve multi-zone air supply, once the duct is installed, it cannot be flexibly switched back to direct-blowing mode. When it is necessary to temporarily enhance air supply or rapidly heat up specific workstations, the equipment is not adaptable enough and cannot meet the diverse air supply needs in large space scenarios.

[0021] Therefore, this utility model proposes a segmented duct air conditioner structure, referring to... Figures 1-4It includes a first housing 100, an evaporator assembly 200, an electric heating assembly 300, an air supply assembly 400, a reserved interface 500, a connecting assembly 600, and a jet air outlet assembly 700. The first housing 100 is provided with an air inlet 110 and an air outlet 120 communicating with the internal space of the first housing 100. The evaporator assembly 200, the electric heating assembly 300, and the air supply assembly 400 are sequentially arranged inside the first housing 100 along the airflow direction from the air inlet 110 to the air outlet 120. The evaporator assembly 200 is used to cool the incoming air. Alternatively, the electric heating component 300 is used to reheat the airflow after heat exchange by the evaporator component 200. The air supply component 400 is used to deliver the airflow to the air outlet 120. The jet air outlet component 700 is detachably fixed to the air outlet 120 side of the first housing 100 through the connecting component 600, and the jet air outlet component 700 covers the air outlet 120. The reserved interface 500 is provided on the air outlet 120 side of the first housing 100. When the jet air outlet component 700 is disassembled, the reserved interface 500 is used to connect to the external air duct.

[0022] The first housing 100 provides installation space for internal components, and constructs airflow channels through the air inlet 110 and air outlet 120 to ensure orderly airflow. The evaporator assembly 200 cools or heats the incoming air, adjusting the air temperature according to different usage requirements. The electric heating assembly 300 reheats the airflow after heat exchange in the evaporator assembly 200 to ensure that the outlet air temperature meets the requirements. The air supply assembly 400 provides power for the airflow, delivering the heat-treated air from inside the housing to the air outlet 120. 20, ensuring that the airflow can be stably delivered to the target area; when the jet nozzle assembly 700 is disassembled, the reserved interface 500 can be directly connected to the external air duct, providing a connection basis for multi-area air supply mode; the connecting component 600 is used to detachably fix the jet nozzle assembly 700 to the air outlet 120 side of the first housing 100. The jet nozzle assembly 700 covers the air outlet 120, guiding the airflow delivered by the air supply assembly 400 into a high-speed jet form, expanding the air supply range, and improving the air supply uniformity in the direct blowing mode. The detachable design of the jet air outlet assembly 700 and the connecting assembly 600, along with the reserved interface 500 on the air outlet 120 side of the first housing 100, allows for flexible switching between direct blowing mode and duct connection mode. When the jet air outlet assembly 700 is installed, it can provide concentrated direct blowing to a specific area, meeting needs such as temporary enhanced air supply and rapid heating. After disassembly, connecting to an external duct via the reserved interface 500 enables uniform air supply to multiple areas, significantly improving the equipment's adaptability in large-space environments. The jet air outlet assembly 700 effectively guides airflow. This design allows for a wider and more uniform airflow range, reducing uneven temperature distribution within the space. Combined with the cooling, heating, and reheating functions of the evaporator assembly 200 and the electric heating assembly 300, the outlet air temperature can be controlled more precisely, improving the overall temperature regulation effect within the space. The jet vent assembly 700 is detachable via the connecting assembly 600, requiring no complex tools or professional skills for installation and disassembly, and can be quickly disassembled and cleaned during routine maintenance. Duct connections only require docking with the reserved interface 500, simplifying operation and reducing time and labor costs for subsequent equipment maintenance.

[0023] After the equipment is started, air enters the first housing 100 through the air inlet 110 and first flows through the evaporator assembly 200. The evaporator assembly 200 cools or preheats the air according to the set requirements, completing the first round of heat exchange. After heat exchange, the air flows to the electric heating assembly 300, which can reheat the air and further adjust the air temperature. The air supply assembly 400 operates, providing power for the qualified airflow and pushing it to the air outlet 120 of the first housing 100. If the jet air outlet assembly 700 is installed, the airflow is guided by the air outlet and blown out in the form of a high-speed jet, realizing local centralized air supply. If the jet air outlet assembly 700 is removed and connected to the external air duct, the airflow enters the air duct through the reserved interface 500 and is transported to multiple areas in the large space, realizing multi-area air supply.

[0024] Airflow may leak from gaps, reducing the direct airflow volume and narrowing the air delivery range. The leaked airflow may also generate vibration and noise, affecting the equipment's performance. Therefore, in one embodiment, the connecting assembly 600 includes a screw, a threaded hole 610, and a mounting hole 611. The threaded hole 610 is located on the side wall of the first housing 100, and the mounting hole 611 is located on the jet nozzle assembly 700 and corresponds to the threaded hole 610. The screw passes through the mounting hole 611 and is threadedly connected to the threaded hole 610, thereby fixing the jet nozzle assembly 700 relative to the first housing 100. The screws are connected to the threaded holes 610 through the mounting holes 611, providing a continuous and stable axial tightening force to tightly press the jet nozzle assembly 700 against the air outlet 120 side of the first housing 100, effectively eliminating gaps and preventing airflow leakage from the connection point, ensuring that the air supply efficiency is not lost; at the same time, the threaded connection has strong resistance to vibration and thermal expansion and contraction, and is not easy to loosen after long-term use, ensuring the stability of air supply in direct blowing mode.

[0025] Disassembly and installation generally require tools and are cumbersome, especially in large spaces such as industrial plants where frequent switching of air supply modes is inefficient. Therefore, in one implementation method, refer to Figure 4The connecting assembly 600 includes a locking head 620 and a limiting box 621. The locking head 620 is fixedly connected to the outer wall of the jet outlet assembly 700, and has a locking groove 622. The limiting box 621 is fixedly connected to the outer wall of the first housing 100. The inner side of the limiting box 621 has a spring 623, a locking block 624, and a sliding groove 625 for the locking head 620 to be inserted. The middle part of the locking block 624 is hinged to the limiting box 621. One end of the block 624 is provided with a locking part 626 that cooperates with the slot 622. The other end of the block 624 is fixedly connected to the spring 623. The other end of the spring 623 is fixedly connected to the limiting box 621. The spring 623 has a tendency to push the end of the block 624 near the sliding groove 625 toward the sliding groove 625. The end of the block 624 away from the sliding groove 625 is provided with a control block 627. The control block 627 protrudes from the outer side wall of the limiting box 621. During installation, simply insert the locking head 620 into the sliding groove 625, and the spring 623 automatically engages with the locking block 624 to secure it. For disassembly, simply press the control block 627 to release the engagement, eliminating the need for screwdrivers or other tools. This improves the efficiency of switching between direct-blowing and duct modes, making it particularly suitable for frequent adjustments in industrial settings. The spring 623 consistently applies a pushing force to the locking block 624, ensuring a tight fit between the locking part 626 and the slot 622, forming a stable mechanical lock that resists airflow impact and equipment vibration during duct operation. Even with prolonged use, the spring 623's elasticity maintains the locking pressure, preventing the loosening issues associated with traditional clips and ensuring stable airflow in direct-blowing mode. During installation, the engaging head 620 is inserted into the sliding groove 625, and its inclined surface presses against the engaging part 626 of the engaging block 624. The engaging block 624 rotates around the hinge axis, compressing the spring 623 at the end away from the sliding groove 625. The spring 623 stores elastic potential energy. When the engaging head 620 is in place, the slot 622 aligns with the engaging part 626, the spring 623 releases its potential energy, and pushes the engaging block 624 to rotate in the opposite direction. Under the action of elastic force, the engaging part 626 is embedded into the slot 622, forming a mechanical lock and fixing the jet vent assembly 700 to the first housing 100. During disassembly, the control block 627 is pressed, and the control block 627 pushes the engaging block. The end of 624 away from the sliding groove 625 causes the locking block 624 to rotate around the hinge axis, the locking part 626 disengages from the locking groove 622, and the spring 623 is compressed again; at this time, the locking head 620 loses its constraint and can be pulled out from the sliding groove 625, realizing the disassembly of the jet air outlet assembly 700; the spring 623 continuously applies pressure to the locking part 626 to ensure that the locking part 626 and the locking groove 622 fit tightly, eliminate the connection gap, and avoid airflow leakage; at the same time, multiple symmetrically distributed locking points can be set to make the force uniform, prevent the jet air outlet assembly 700 from shifting due to vibration, and ensure the air supply effect of the direct blowing mode.

[0026] If a large-diameter air outlet is used to increase airflow, the airflow velocity will decrease due to the increased cross-sectional area, weakening the jet penetration and making it impossible to quickly deliver air at the required temperature to a more distant workstation. Therefore, in one embodiment, the jet outlet assembly 700 includes a second housing 710 and multiple jet outlet bodies 720. All jet outlet bodies 720 are arranged side-by-side on the second housing 710, and all of the jet outlet bodies 720 are connected to the internal space of the second housing 710. The side-by-side arrangement of multiple jet outlet bodies 720 can disperse the airflow into multiple high-speed jets, simultaneously delivering them to the same direction or adjacent areas. Compared to a single air outlet, the air delivery coverage width is significantly increased, enabling rapid coverage of multiple adjacent workstations and improving the temperature uniformity of local areas. Each jet outlet body 720 arranged side-by-side still has a small-diameter design, which, based on the principle of fluid continuity, maintains the high-speed jet characteristics, ensuring that the airflow has sufficient delivery distance and penetration, and can quickly deliver air at the required temperature to the target workstation.

[0027] Impurities may enter the housing and adhere to the evaporator fins, clogging the heat exchange channels, or enter the air supply assembly 400 and wear down the impeller, leading to increased air supply noise and shortened service life. Therefore, in one embodiment, a filter assembly 800 is also included. The filter assembly 800 includes a filter plate 810, a slide groove 820, and a frame 830. The frame 830 is disposed on the air inlet side of the first housing 100 and covers the air inlet 110. The slide groove 820 is disposed on the frame 830. One end of the filter plate 810 is inserted into the slide groove 820 and slidably connected to the slide groove 820. The other end of the filter plate 810 is provided with a handle 840. The filter plate 810 is slidably connected to the frame 830 via the slide groove 820, forming a drawer-type structure with the handle 840. No tools are needed for cleaning; simply pull the handle 840 to remove the filter plate 810. This reduces the time and labor costs of frequently cleaning the filter assembly 800 in industrial settings and avoids the cumbersome disassembly of traditional fixed structures. The filter plate 810 covers the air inlet 110, effectively intercepting dust and particulate impurities in the air and preventing them from entering the first housing 100. This prevents impurities from adhering to the surface of the evaporator assembly 200 and clogging the heat exchange channels, or from entering the air supply assembly 400 and causing impeller wear, thus extending the service life of core components such as the evaporator and air supply assembly 400 and reducing the equipment failure rate.

[0028] Low air pressure may prevent the airflow from forming a high-speed jet and make it difficult to overcome duct resistance, resulting in the inability to switch properly between the two air delivery modes of the segmented duct air conditioner, significantly reducing equipment adaptability. Therefore, in one embodiment, the air delivery assembly 400 includes a motor and a volute impeller driven by the motor. The inlet end of the volute impeller faces the outlet end of the evaporator assembly 200, and the outlet end of the volute impeller faces the outlet 120. The volute impeller draws airflow radially in and converts kinetic energy into static pressure energy through the diffusion channel of the volute, outputting high-pressure airflow to meet the high-speed jet requirements of the jet outlet and overcome the friction resistance of the external duct. It adapts to both direct blowing and duct modes, solving the problem of insufficient air pressure in traditional impellers. The inlet end of the volute impeller faces the outlet end of the evaporator assembly 200, and the outlet end faces the outlet 120, reducing energy loss during airflow transport and ensuring that the treated air is efficiently delivered to the target area.

[0029] Uneven airflow from the volute impeller directly enters the jet nozzle assembly 700, which may cause some nozzles to spray air further away while others spray air closer away, resulting in localized overheating or overcooling in the direct-blowing area. Therefore, in one embodiment, a diffuser box 900 is also included. The diffuser box 900 is detachably disposed at the air outlet 120 of the first housing 100 and is located between the air outlet 120 and the jet nozzle assembly 700. The diffuser box 900 has a plurality of evenly spaced slots 910 for uniformly distributing the airflow and guiding it to the air inlet of the jet nozzle assembly 700. The multiple uniform slots 910 on the diffuser box 900 can disperse and reorganize the uneven airflow output from the volute impeller. By dispersing the airflow through the slots 910, each jet nozzle body 720 obtains an airflow with a consistent velocity, resulting in uniform jet intensity and coverage, avoiding localized excessive or insufficient airflow, and improving temperature uniformity in direct-blowing mode. The slots 910 of the diffuser box 900 can also pre-dissolve eddies, allowing the airflow to flow smoothly towards the jet nozzles and reducing collision noise between the airflow and the nozzles. Specifically, the diffuser box 900 is detachably mounted on the first housing 100 by clips or screws, and the diffuser box 900 is disassembled simultaneously when the jet nozzle assembly 700 is disassembled.

[0030] When directly connecting to the air duct, the interface gap is large, which may lead to insufficient airflow and poor temperature regulation in remote areas when supplying air to multiple areas. Therefore, in one embodiment, the reserved interface 500 includes a flange 510 and a gasket 520 surrounding the air outlet 120. The flange 510 has multiple connection holes, and the gasket 520 is disposed on the mating surface of the flange 510. The flange 510 is connected to the flange of the external air duct through the connection holes, and the gasket 520 is used to seal the connection between the flange 510 and the flange of the external air duct. The sealing gasket 520 is attached to the mating surface of the flange 510. After being pressed tightly against the external duct flange, it fills the interface gap, eliminates air leakage channels, reduces airflow loss, and ensures that each target area receives sufficient airflow during multi-zone air supply, guaranteeing temperature regulation effects while avoiding energy waste. The flange 510 is set around the air outlet 120, providing a unified mating benchmark. The external duct only needs to be fixed by bolts through the connection holes on the flange 510, without the need for repeated position adjustments. The standardized connection hole layout is compatible with most industrial duct flange specifications, reducing on-site construction difficulty. The flange 510 is rigidly connected to the external duct by bolts, with strong vibration resistance, preventing duct displacement due to equipment operation vibration. The sealing gasket 520 is made of aging-resistant and temperature-resistant materials (such as rubber and silicone), which are not prone to deformation and failure after long-term use, ensuring stable interface sealing performance and reducing the frequency of later maintenance.
