Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing a portable air conditioner. Background Technology

[0002] Currently, both wall-mounted and floor-standing air conditioners need to be fixed in a limited location and cannot be moved. Therefore, portable air conditioners have emerged. A portable air conditioner mainly consists of a casing, an indoor airflow assembly, and an outdoor airflow assembly. Both the indoor and outdoor airflow assemblies are housed within the casing. The casing has indoor air inlets and outlets corresponding to the indoor airflow assembly, and similarly, outdoor air inlets and outlets corresponding to the outdoor airflow assembly. To facilitate movement, portable air conditioners are typically designed to be small, allowing for rapid relocation and temperature regulation in the affected location or room.

[0003] In portable air conditioners using related technologies, both the indoor and outdoor air inlets on the casing are equipped with filters. The filters are inserted into the inner side of the casing. To facilitate filter installation and removal, guide rails are provided on two opposite sides of the indoor / outdoor air inlets, with the two corresponding edges of the filter located within these guide rails. The guide rails are typically constructed as two bent, connected side ribs to form guide grooves with the casing. Alternatively, the guide rails can be constructed as guide strips with guide grooves. The openings of the two guide grooves face each other. However, dust and debris easily accumulate inside the guide grooves, and long-term accumulation may cause the guide rails to become difficult to slide or jam, affecting filter installation and removal. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of dust and debris accumulating in the guide groove of the filter in a portable air conditioner, causing poor sliding or jamming.

[0005] This utility model provides a portable air conditioner, comprising: a housing, with at least one heat exchange cavity defined inside, an air inlet corresponding to the heat exchange cavity on the housing, a portion of the housing plate recessed into the heat exchange cavity to form a mounting side plate, and an installation gap formed between the mounting side plate and the air inlet; a base portion and a top cover portion, respectively distributed at both ends in the height direction of the heat exchange cavity and detachably connected to the housing; a first guide member extending along the width direction of the air inlet portion and respectively arranged at two opposite sides in the height direction of the air inlet portion; a second guide member respectively disposed on the base portion and the top cover portion, the second guide member extending along the height direction of the housing and capable of forming a guide gap with the first guide member; a filter portion having a free end and a fixed end arranged oppositely, the free end being inserted through the installation gap and slidably inserted into the inner side of the air inlet portion through the guide gap, and the fixed end being engaged with the mounting side plate.

[0006] With the above technical solution, an installation gap can be formed between the mounting side plate and the air inlet, facilitating the insertion of the filter unit into the inner side of the housing. By placing the first guide member on the inner side of the housing and the second guide member on the corresponding base and top cover of the heat exchange chamber to cooperate with the first guide member and form a guide gap, dust or impurities can be avoided from accumulating between the first and second guide members, thus preventing blockage of the guide gap and allowing the filter unit to be inserted into the guide gap through the installation gap. Furthermore, this arrangement simplifies the complexity of the filter unit's guiding mechanism and improves structural reliability. Moreover, the filter unit slides along the guide gap and is inserted into the inner side of the air inlet, enabling quick installation and removal of the filter unit without causing sliding difficulties or jamming, thus improving the installation efficiency of the filter unit.

[0007] In an optional embodiment of the above-mentioned portable air conditioner, a stop member is further included, which is disposed on the inner side of the housing and located at two side ends of the air inlet in the width direction, respectively, along with the mounting side plate. The stop member is configured to restrict the movement of the free end.

[0008] The stopper can limit the movement of the filter unit, preventing it from sliding excessively during installation and ensuring the accuracy of its installation position.

[0009] In an optional embodiment of the above-mentioned portable air conditioner, the stop member includes: a first stop plate, which is fixedly connected to the outer shell and extends toward the interior of the heat exchange chamber; and a second stop plate, which is bent and connected to the first stop plate and together with the first stop plate and the outer shell, encloses an accommodating gap with the opening facing the mounting side plate.

[0010] This arrangement creates a accommodating gap that can stably accommodate the free end of the filter section. The first stop plate limits the movement of the filter section during installation, while the second stop plate protects the free end of the filter section.

[0011] In the optional implementation of the above-mentioned portable air conditioner, a snap-fit ​​assembly is also included, the snap-fit ​​assembly comprising: at least one bayonet opening on the mounting side plate; and a buckle disposed on the inner side of the fixed end and snapping into the bayonet opening.

[0012] The snap-fit ​​assembly ensures a stable connection between the filter unit and the mounting side plate. When the filter unit slides along the guide gap into the inner side of the air inlet and reaches the appropriate position, the snap-fit ​​accurately engages, achieving a secure connection between the filter unit and the mounting side plate. This snap-fit ​​method not only provides a reliable connection but also facilitates disassembly.

[0013] In an optional embodiment of the above-mentioned portable air conditioner, the filter unit includes: a mounting frame, comprising a frame and a connecting plate, wherein the connecting plate is configured as the fixed end and is connected to the frame by an arc bend, and the side of the frame opposite to the connecting plate is configured as a free end; and a filter screen, detachably mounted on the frame.

[0014] On the one hand, the curved connecting plates and frames make the overall structure of the filter unit more stable, preventing the filter from deforming during installation and use. On the other hand, the detachable filter allows users to easily replace it with different types or specifications to meet various filtration requirements. For example, a pre-filter can be used in environments with good air quality, while a medium-efficiency or high-efficiency filter can be used in environments with more dust or higher air quality requirements.

[0015] In an optional embodiment of the portable air conditioner described above, the outer surface of the connecting plate is provided with a handhold.

[0016] The handheld part allows the filter to be pulled out or inserted from the guide gap, improving the efficiency of filter assembly and disassembly.

[0017] In an optional embodiment of the aforementioned portable air conditioner, it further includes: an outdoor air duct assembly disposed within the housing and separating the heat exchange chamber into an indoor cavity and an outdoor cavity distributed vertically; the outdoor air duct assembly connects to the outdoor cavity and includes at least opposing upper and lower air duct plates; the upper air duct plate faces the indoor cavity and is configured as the base portion of the indoor cavity; the lower air duct plate faces the outdoor cavity and is configured as the top cover portion of the outdoor cavity; wherein, the air inlet includes an indoor air inlet corresponding to the indoor cavity and an outdoor air inlet corresponding to the outdoor cavity; a chassis, and the... The outer casing is detachably connected and together with the lower air duct plate encloses the outdoor cavity, and the chassis constitutes the top cover of the outdoor cavity; an outdoor fan is disposed between the upper and lower air duct plates and is configured to drive air to circulate in the outdoor cavity; an indoor heat exchanger is disposed in the indoor cavity corresponding to the indoor air inlet; an air duct cover is disposed at the top of the indoor heat exchanger and together with the upper air duct plate encloses the indoor air duct, and the air duct cover is constructed as the top cover of the indoor cavity; an indoor fan is disposed in the indoor air duct and is configured to drive air to circulate in the indoor cavity.

[0018] This structural layout allows indoor and outdoor airflow to circulate relatively independently within their respective indoor and outdoor cavities, avoiding mutual interference and improving the heat exchange efficiency and operational stability of the portable air conditioner. The outdoor air duct assembly effectively separates the heat exchange chamber into indoor and outdoor cavities, isolating the indoor and outdoor air environments and preventing cross-contamination of heat or cold, thus improving energy efficiency. Filter sections are located at the indoor and outdoor air inlets respectively, effectively filtering the air entering the indoor and outdoor cavities. This ensures clean air entering the portable air conditioner, reduces damage to internal components from dust and impurities, and extends its service life.

[0019] In an optional embodiment of the above-mentioned portable air conditioner, the first guide member includes a first guide strip and a second guide strip, the first guide strip extending to two opposite sides in the height direction of the indoor air inlet, and the second guide strip extending to two opposite sides in the height direction of the outdoor air inlet; the second guide member includes a first guide plate and a second guide plate, the first guide plate extending to the duct cover and the upper duct plate respectively corresponding to the first guide strip, and the second guide plate extending to the lower duct plate and the chassis respectively corresponding to the second guide strip.

[0020] The first and second guide plates cooperate with the first and second guide strips respectively, forming a guiding gap that ensures the filter unit can slide smoothly at the air inlets of both the indoor and outdoor cavities. This prevents the filter unit from shifting or shaking during sliding, ensuring the stability and accuracy of the filter unit installation and further improving the overall performance and reliability of the portable air conditioner. Furthermore, it allows the installation and removal of the filter unit to be performed independently and efficiently at both the indoor and outdoor air inlets, without interference.

[0021] In an optional embodiment of the above-mentioned portable air conditioner, the indoor air inlet includes a plurality of indoor air inlet holes formed on the outer casing; the inner side of the outer casing is provided with a plurality of cross-connected first reinforcing ribs; the first reinforcing ribs are arranged to avoid the indoor air inlet holes.

[0022] The design of multiple indoor air inlets not only ensures sufficient air intake area, which helps increase the airflow into the indoor cavity and thus improves the efficiency of air circulation and heat exchange, but also avoids forming large openings on the outer shell, thus improving the structural stability of the outer shell. At the same time, the inclusion of a first reinforcing rib that avoids obstructing airflow further enhances the structural strength of the outer shell.

[0023] In an optional embodiment of the above-mentioned portable air conditioner, the outdoor air inlet includes a plurality of outdoor air inlet holes formed on the outer casing; the inner side of the outer casing is provided with a plurality of cross-connected second reinforcing ribs; the second reinforcing ribs are arranged to avoid the outdoor air inlet holes.

[0024] The design of multiple outdoor air inlets not only ensures sufficient air intake area, which helps increase the airflow into the outdoor cavity and thus improves the efficiency of air circulation and heat exchange, but also avoids forming large openings on the outer shell, thus improving the structural stability of the shell. Simultaneously, the inclusion of a second reinforcing rib that avoids obstructing airflow further enhances the structural strength of the shell. Attached Figure Description

[0043] Combination Figures 1 to 11 As shown, this utility model provides a portable air conditioner, including a housing 100, a base, a top cover, a first guide 210, a second guide 220, and a filter 300.

[0044] The housing 100 defines at least one heat exchange chamber 110 inside. The housing 100 has an air inlet 120 corresponding to the heat exchange chamber 110. A portion of the housing 100 is recessed into the heat exchange chamber 110 to form a mounting side plate 130. The mounting side plate 130 extends along the height direction of the housing 100 and forms a mounting gap 101 with the air inlet 120. A base portion and a top cover portion are distributed opposite each other at both ends of the heat exchange chamber 110 in the height direction and are detachably connected to the housing 100. A first guide member 210 extends along the width direction of the air inlet 120 and is respectively arranged at two opposite sides of the air inlet 120 in the height direction. A second guide member 220 is respectively provided on the base portion and the top cover portion, extending along the height direction of the housing 100 and forming a guide gap 102 with the first guide member 210. The filter section 300 has a free end 301 and a fixed end 302 arranged opposite to each other. The free end 301 is inserted through the mounting gap 101 and slidably inserted into the inner side of the air inlet section 120 through the guide gap 102. The fixed end 302 is engaged with the mounting side plate 130.

[0045] Optionally, a portion of the outer casing 100 is recessed into the heat exchange cavity 110 to form a mounting side plate 130, with a mounting gap 101 between the mounting side plate 130 and the air inlet 120. This not only avoids occupying external space of the outer casing 100 and creating a protruding structure that could scratch the user, but also allows for more efficient use of the internal space of the outer casing 100. While ensuring the mounting gap 101 is appropriately sized, it does not excessively occupy space in the heat exchange cavity 110, thus ensuring the compactness and rationality of the portable air conditioner's internal structure. Furthermore, the mounting gap 101 provides sufficient space for the insertion of the filter unit 300, ensuring smooth installation of the filter unit 300.

[0046] Furthermore, this arrangement allows the mounting side panel 130 and the outer casing 100 to be integrally molded, which not only helps to enhance the overall structural strength of the outer casing 100 and reduce safety hazards caused by loosening or damage to the connection points, but also simplifies the manufacturing process and reduces production costs. During the long-term use of the portable air conditioner, the integrally molded mounting side panel 130 and outer casing 100 can better withstand various external forces, ensuring the stability and reliability of the portable air conditioner. At the same time, this integral design also makes the portable air conditioner's appearance more concise and aesthetically pleasing, improving the overall quality of the product.

[0047] Since the mounting side plate 130 extends along the height direction of the housing 100, a vertically extending mounting gap 101 is formed between it and the air inlet 120. In order to allow the filter 300 to be mounted on the inner side of the air inlet 120 through the mounting gap 101, guide components extending in their own width direction are provided at both ends of the air inlet 120 in the height direction. The height direction of the air inlet 120 is consistent with the height direction of the housing 100, and the width direction of the air inlet 120 is consistent with the width direction of the housing 100.

[0048] Optionally, a first guide member 210 is formed on the inner side of the housing 100 and extends along the width direction of the air inlet 120. The first guide member 210 is respectively arranged at two opposite side ends in the height direction of the air inlet 120. A second guide member 220 is respectively provided on the base portion and the top cover portion. The second guide member 220 extends along the height direction of the housing 100 and can form a guide gap 102 with the first guide member 210. That is, the setting position and extension direction of the second guide member 220 match the first guide member 210. In this way, the second guide member 220 can be formed in two parts (i.e., the base portion and the top cover portion) that are detachably connected to the housing 100.

[0049] Therefore, the second guide member 220 and the first guide member 210 cooperate to form a guide gap 102. Since there are no connecting parts between them, dust or impurities are unlikely to accumulate in the guide gap 102, making clogging a rare problem. During the installation or removal of the filter unit 300, issues such as poor sliding or jamming can be avoided, effectively improving the installation efficiency of the filter unit 300. Furthermore, because the guide gap 102 is not prone to dust accumulation and clogging, it also helps maintain the cleanliness of the air inside the heat exchange chamber 110, reducing the impact of dust and impurities on the performance and air quality of the portable air conditioner, providing users with a healthier and more comfortable operating environment.

[0050] The filter section 300 has a free end 301 and a fixed end 302 arranged opposite to each other. The free end 301 is inserted through the mounting gap 101 and slidably inserted into the inner side of the air inlet section 120 through the guide gap 102. The fixed end 302 is engaged with the mounting side plate 130.

[0051] If the filter section 300 experiences sliding difficulties or jamming during installation, the user may easily apply excessive force, potentially damaging or bending the free end of the filter section 300, causing significant problems for subsequent installation or disassembly. Therefore, in this design, the first guide member 210 and the second guide member 220 are respectively formed on the outer casing 100 and two components detachably connected to the outer casing 100 (i.e., the base and the top cover). This ensures the flatness and integrity of the free end 301 of the filter section 300, extends its service life, and reduces maintenance costs. This arrangement also facilitates the inspection, cleaning, or replacement of the filter section 300 during routine maintenance of the portable air conditioner, allowing for timely detection and resolution of potential problems, further improving the reliability and stability of the portable air conditioner.

[0052] Optionally, the fixed end 302 of the filter unit 300 is snapped into the mounting side plate 130. This secures the filter unit 300, preventing it from loosening or shifting due to vibration during operation of the portable air conditioner. When air enters the heat exchange chamber 110 through the air inlet 120, the filter unit 300 stably filters the air, ensuring consistent and reliable filtration performance. Furthermore, the snap-fit ​​design makes disassembly of the filter unit 300 very convenient. When cleaning or replacing the filter unit 300 is required, simply release the snap-fit ​​to remove it, improving maintenance efficiency. In addition, the tightness of the snap-fit ​​effectively prevents unfiltered air from bypassing the filter unit 300 and entering the heat exchange chamber 110, further ensuring the cleanliness of the air inside the portable air conditioner and its heat exchange efficiency.

[0053] Alternatively, the fixed end 302 of the filter section 300 is screwed to the mounting side plate 130.

[0054] With the above technical solution, an installation gap can be formed between the mounting side plate and the air inlet, facilitating the insertion of the filter unit into the inner side of the housing. By placing the first guide member on the inner side of the housing and the second guide member on the corresponding base and top cover of the heat exchange chamber to cooperate with the first guide member and form a guide gap, dust or impurities can be avoided from accumulating between the first and second guide members, thus preventing blockage of the guide gap. Furthermore, the filter unit is inserted into the guide gap through the installation gap, and further, the filter unit slides along the guide gap and is inserted into the inner side of the air inlet. This allows for quick installation and removal of the filter unit without problems such as poor sliding or jamming, improving the installation efficiency of the filter unit.

[0055] In an optional embodiment of the portable air conditioner described above, a stop member 140 is also included. The stop member 140 is disposed on the inner side of the housing 100 and is located at two side ends of the air inlet 120 in the width direction, respectively, along with the mounting side plate 130. The stop member 140 is configured to restrict the movement of the free end 301.

[0056] The stop 140 limits the installation of the filter unit 300, preventing excessive sliding during installation and ensuring accurate positioning. When the filter unit 300 is slidably inserted into the inner side of the air inlet 120 along the guide gap 102, its free end 301 is blocked at the stop 140, stopping it in the correct position. This ensures accurate positioning of the filter unit 300 in the width direction of the air inlet 120, allowing for better alignment and ensuring proper air filtration. During operation, the stop 140 also reduces vibration and increases the stability of the filter unit 300, thus improving overall reliability and filtration efficiency.

[0057] Optionally, the stop 140 has a buffer layer on its side facing the mounting side plate 130. The buffer layer can be made of silicone, foam, or other materials. Alternatively, a buffer layer may not be provided.

[0058] Alternatively, stop 140 may not be provided.

[0059] In an optional embodiment of the portable air conditioner described above, the stop member 140 includes a first stop plate 141 and a second stop plate 142. The first stop plate 141 is fixedly connected to the outer casing 100 and extends toward the interior of the heat exchange chamber 110. The second stop plate 142 is bent and connected to the first stop plate 141, and together with the first stop plate 141 and the outer casing 100, it encloses an accommodating gap with the opening facing the mounting side plate 130.

[0060] With this arrangement, the resulting accommodating gap can stably accommodate the free end 301 of the filter section 300. The first stop plate 141 provides a limiting function for the filter section 300 during installation, while the second stop plate 142 provides protection for the free end 301 of the filter section 300.

[0061] Specifically, the stop member 140 structure, composed of the first stop plate 141 and the second stop plate 142, can better adapt to the shape and installation requirements of the free end 301 of the filter section 300. The first stop plate 141 extends into the heat exchange chamber 110, providing a stable support base for the second stop plate 142, making the overall structure of the stop member 140 more stable; while the accommodating gap formed by the bending connection between the second stop plate 142 and the first stop plate 141 has its opening facing the mounting side plate 130, which can accurately limit and guide the free end 301 of the filter section 300.

[0062] Optionally, the first stop plate 141 is arranged along the height direction of the housing 100 and is at least the same height as the air inlet 120. The height of the second stop plate 142 is greater than or equal to the height of the first stop plate 141. Alternatively, the height of the second stop plate 142 is less than the height of the first stop plate 141.

[0063] When the filter unit 300 is slidably inserted into the inner side of the air inlet 120 along the guide gap 102, the free end 301 can smoothly slide along the guide gap 102 and enter the receiving gap, stopping its sliding under the obstruction of the first stop plate 141, achieving precise positioning. This improves the accuracy of the filter unit 300's installation position, making its position in the width direction of the air inlet 120 more precise, ensuring that air can be filtered more effectively through the filter unit 300, thus improving the filtration efficiency and air quality of the portable air conditioner. Simultaneously, the second stop plate 142 shields the free end 301, allowing the receiving gap to accommodate it, thereby preventing minor deformations or displacements that may occur during installation, and preventing problems such as warping during long-term use of the portable air conditioner, thus ensuring the flatness of the filter unit 300 after it is snapped and fixed to the mounting side plate 130.

[0064] Optionally, the width of the receiving gap is the same as the width of the guide gap 102.

[0065] Furthermore, the stop 140 will not cause any additional obstruction to the pushing or pulling of the filter 300 during installation and disassembly. The filter 300 only needs to slide along the guide gap 102, thereby ensuring the convenience and safety of the filter 300 during installation and disassembly.

[0066] Furthermore, the bent stop 140 increases the contact area with the free end 301 of the filter section 300, effectively reducing the shaking of the filter section 300 caused by vibration during operation, enhancing its stability, and ensuring the overall reliability of the portable air conditioner. On the other hand, it also prevents dust and other debris from entering the receiving gap, reducing interference with the installation and positioning of the filter section 300, further improving the stability and reliability of the filter section 300 installation in the portable air conditioner. Since the opening of the receiving gap faces the mounting side plate 130, it does not obstruct the filter section 300 during disassembly, facilitating cleaning or replacement.

[0067] In an optional embodiment of the portable air conditioner described above, a snap-fit ​​assembly is also included, comprising a latch 410 and a buckle 420. At least one latch 410 is formed in the mounting side plate 130. The buckle 420 is disposed on the inner side of the fixed end 302 and snaps into the latch 410.

[0068] The snap-fit ​​assembly ensures the stability of the connection between the filter unit 300 and the mounting side plate 130. When the filter unit 300 is slidably inserted into the inner side of the air inlet 120 along the guide gap 102 and reaches the appropriate position, the snap fastener 420 can accurately engage with the slot 410, thereby achieving a firm connection between the filter unit 300 and the mounting side plate 130. This prevents the filter unit 300 from loosening or falling off due to vibration or other reasons during use, ensuring that the filter unit 300 can continue to function effectively and improving the air quality regulation effect of the portable air conditioner.

[0069] Furthermore, this snap-fit ​​connection method is not only reliable but also easy to disassemble. The engagement of the bayonet 410 and the clip 420 is simple and efficient, ensuring the filter unit 300 is securely installed while facilitating user disassembly. Moreover, the snap-fit ​​assembly has a relatively compact structure, minimizing its space requirements within the portable air conditioner and contributing to a more compact and rational internal structure.

[0070] Optionally, multiple latches 410 are provided at intervals along the height direction of the mounting side plate 130, and the number and setting position of the latches 420 are matched with the latches 410.

[0071] In an optional embodiment of the portable air conditioner described above, the filter unit 300 includes a mounting frame 310 and a filter screen. The mounting frame 310 includes a frame 311 and a connecting plate 312, wherein the connecting plate 312 is configured as a fixed end and is connected to the frame 311 by an arc bend, and the side of the frame 311 opposite to the connecting plate 312 is configured as a free end. The filter screen is detachably mounted to the frame 311.

[0072] On the one hand, by setting the connecting plate 312 and the frame 311 with arc bending connection, the smooth transition connection between the filter part 300 and the mounting side plate 130 can be better realized, which can make the overall structure of the filter part 300 more stable after installation, and make the filter screen less prone to deformation during installation and use; on the other hand, by setting the filter screen that can be detached and installed, it is convenient for users to replace different types or specifications of filter screens according to actual needs to meet different filtration requirements.

[0073] Optionally, the filter screen includes one or more of the following: pre-filter, medium-efficiency filter, and high-efficiency filter.

[0074] Using different types of filters in combination can more comprehensively filter pollutants of varying sizes, such as dust, pollen, smoke, and bacteria, effectively improving air filtration and providing users with a better indoor air environment. The pre-filter filters out larger dust and debris, the medium-efficiency filter further intercepts smaller particles, and the high-efficiency filter removes tiny bacteria and viruses. The combination of different filter types allows for flexible adjustments based on actual air quality conditions, further enhancing the practicality and adaptability of portable air conditioners. For example, a pre-filter can be used in environments with good air quality, while a medium-efficiency or high-efficiency filter can be used in environments with more dust or higher air quality requirements.

[0075] The removable filter design facilitates daily cleaning and replacement. After a period of use, a large amount of dust and impurities accumulate on the filter's surface, affecting filtration efficiency and airflow. Users can remove the filter from frame 311 for cleaning or replacement to ensure the continuous and efficient operation of the filter unit 300, maintaining the portable air conditioner's filtration performance and air purification effect. Furthermore, this design reduces maintenance costs, as only the filter needs to be replaced, eliminating the need to replace the entire filter unit 300.

[0076] In an optional embodiment of the portable air conditioner described above, the outer surface of the connecting plate 312 is provided with a handheld part 313.

[0077] By using the handheld part 313, the filter part 300 can be pulled out or inserted from the guide gap 102, avoiding potential contamination from direct contact with the surface of the filter screen of the filter part 300.

[0078] Optionally, the surface of the handle 313 can be provided with an anti-slip texture to further increase friction and prevent slippage during operation, thereby improving operational safety. Optionally, the color of the handle can contrast sharply with the connecting plate 312, making it easier for users to quickly locate and operate the filter unit 300 even in dimly lit environments, enhancing ease of use.

[0079] In the optional embodiment of the aforementioned portable air conditioner, it further includes an outdoor duct assembly 500, a chassis 150, an indoor heat exchanger 710, a duct cover 720, and an indoor fan. The outdoor duct assembly 500 is disposed within the housing 100 and separates the heat exchange chamber 110 into an indoor cavity 111 and an outdoor cavity 112 distributed vertically. The outdoor duct assembly 500 connects to the outdoor cavity 112 and includes at least an upper duct plate 510 and a lower duct plate 520. The upper duct plate 510 faces the indoor cavity 111 and is configured as the base portion of the indoor cavity 111, while the lower duct plate 520 faces the outdoor cavity 112 and is configured as the top cover portion of the outdoor cavity 112. The air inlet 120 includes an indoor air inlet 121 corresponding to the indoor cavity 111 and an outdoor air inlet 122 corresponding to the outdoor cavity 112. The chassis 150 is detachable from the housing 100. The chassis 150 forms the top cover of the outdoor cavity 112, which is connected to the upper air duct 510 and the lower air duct 520. The outdoor fan 610 is located between the upper air duct 510 and the lower air duct 520 and is configured to drive air to circulate in the outdoor cavity 112. The indoor heat exchanger 710 is located in the indoor cavity 111, corresponding to the indoor air inlet 121. The air duct cover 720 is located at the top of the indoor heat exchanger 710 and, together with the upper air duct 510, encloses the indoor air duct. The air duct cover 720 is constructed as the top cover of the indoor cavity 111. The indoor fan is located in the indoor air duct and is configured to drive air to circulate in the indoor cavity 111.

[0080] This structural layout allows indoor and outdoor airflow to circulate relatively independently within the indoor cavity 111 and outdoor cavity 112, avoiding mutual interference between airflows and improving the heat exchange efficiency and operational stability of the portable air conditioner. The outdoor air duct assembly 500 effectively isolates the indoor and outdoor air environments of the heat exchange chamber 110, preventing cross-contamination of heat or cold and improving energy efficiency. The filter unit 300 is positioned corresponding to the indoor air inlet 121 and the outdoor air inlet 122, effectively filtering the air entering the indoor cavity 111 and outdoor cavity 112. This ensures clean air entering the portable air conditioner, reduces damage to internal components from dust and impurities, and extends its service life.

[0081] Optionally, an outdoor heat exchanger 730 is provided inside the outdoor cavity 112 and mounted on the chassis 150. The chassis 150 includes at least a plate body and a peripheral portion arranged circumferentially around the plate body and extending into the outdoor cavity 112. The second guide member 220 is correspondingly disposed on the peripheral portion.

[0082] In this design, the indoor fan drives indoor air through the indoor air inlet 121, which is effectively filtered by the filter section 300 before entering the indoor cavity 111. The air then undergoes heat exchange through the indoor heat exchanger 710, thereby regulating the indoor temperature. Meanwhile, the outdoor fan 610 drives air through the outdoor air inlet 122, which is also effectively filtered by the filter section 300 before entering the outdoor cavity 112. This air carries away the heat generated by the outdoor heat exchanger 730, thus achieving heat exhaust.

[0083] Furthermore, the upper and lower duct plates of the outdoor duct assembly 500 effectively guide airflow, reduce duct resistance, and improve air circulation efficiency. The detachable connection between the chassis 150 and the outer casing 100 facilitates cleaning and maintenance of the outdoor cavity 112, ensuring the normal operation of components such as the outdoor fan 610 and the outdoor heat exchanger. Simultaneously, the indoor duct enclosed by the duct cover 720 and the upper duct plate 510 rationally guides the flow of indoor air, ensuring even distribution of indoor air throughout the space and enhancing the user experience.

[0084] During the operation of a portable air conditioner, all components work together in coordination. The stable filtration of the 300 filter section ensures the cleanliness of the air entering the room, the efficient operation of the indoor and outdoor fans realizes air circulation and heat exchange, and the rational design of the air duct structure improves the operating efficiency of the entire system.

[0085] During airflow, the outdoor fan 610 drives outdoor air from the outdoor air inlet 122 into the outdoor cavity 112, where it undergoes heat exchange in the outdoor heat exchanger 730 before being discharged from the outdoor air outlet, thus achieving heat exchange on the outdoor side. Meanwhile, the indoor fan drives indoor air from the indoor air inlet 121 into the indoor cavity 111, where it undergoes temperature regulation in the indoor heat exchanger 710 before being returned to the room from the indoor air outlet, achieving the purpose of regulating the indoor temperature.

[0086] Furthermore, the detachable connection between the outer casing 100 and the base, top cover, and chassis 150 not only facilitates the assembly and transportation of the air conditioner but also provides convenience for later maintenance and repair. When a malfunction occurs inside the air conditioner, repair personnel can more easily disassemble the relevant components for inspection, improving repair efficiency and reducing repair costs.

[0087] In the optional implementation of the above-mentioned portable air conditioner, the first guide member 210 includes a first guide strip 211 and a second guide strip 212. The first guide strip 211 extends to two opposite sides in the height direction of the indoor air inlet 121, and the second guide strip 212 extends to two opposite sides in the height direction of the outdoor air inlet 122. The second guide member 220 includes a first guide plate 221 and a second guide plate 222. The first guide plate 221 extends to the air duct cover 720 and the upper air duct plate 510 respectively, corresponding to the first guide strip 211. The second guide plate 222 extends to the lower air duct plate 520 and the chassis 150 respectively, corresponding to the second guide strip 212.

[0088] The first guide plate 221 and the second guide plate 222 cooperate with the first guide bar 211 and the second guide bar 212 respectively, forming a guide gap 102. This ensures that the filter unit 300 can be smoothly slidably installed at the air inlet 120 of both the indoor cavity 111 and the outdoor cavity 112, thereby reducing the complexity of the guide structure of the filter unit 300. Even if the filter unit 300 deviates or shakes during sliding, this ensures the stability and accuracy of the filter unit 300 installation, further improving the overall performance and reliability of the portable air conditioner. This also allows the installation and removal of the filter unit 300 to be performed independently and efficiently at both the indoor air inlet 121 and the outdoor air inlet 122, without interference.

[0089] When the filter unit 300 needs cleaning or replacement, the user can operate the filter units 300 at the corresponding indoor air inlet 121 and outdoor air inlet 122 separately according to the actual situation, without having to disassemble other parts as a whole, which greatly improves the convenience of maintenance. At the same time, this guiding structure can also prevent the filter unit 300 from shifting or shaking during sliding, ensuring the stability and accuracy of the filter unit 300 installation, and further improving the overall performance and reliability of the portable air conditioner.

[0090] In the optional implementation of the above-mentioned portable air conditioner, the indoor air inlet 121 includes a plurality of indoor air inlet holes 1210 formed on the outer casing 100; the inner side of the outer casing 100 is provided with a plurality of cross-connected first reinforcing ribs 161; the first reinforcing ribs 161 are arranged to avoid the indoor air inlet holes 1210.

[0091] The design of multiple indoor air inlets 1210 not only ensures sufficient air intake area, which is beneficial for increasing the airflow into the indoor cavity 111 and thus improving the efficiency of air circulation and heat exchange, but also avoids forming large openings on the outer casing 100, thereby improving the structural stability of the outer casing 100. Simultaneously, the placement of the first reinforcing rib 161, which avoids obstructing airflow, further enhances the structural strength of the outer casing 100, making it less prone to deformation during long-term use and ensuring the overall structural stability of the portable air conditioner. The placement of the first reinforcing rib 161, which avoids obstructing the indoor air inlets 1210, ensures that air can smoothly enter the indoor cavity 111 through the indoor air inlets 1210.

[0092] This rational layout ensures more even indoor airflow, effectively drawing indoor air into the indoor cavity 111 for processing and creating a more comfortable indoor environment for users. Furthermore, the first reinforcing rib 161 strengthens the outer casing 100, improving the portable air conditioner's durability and reducing the probability of malfunctions due to damage to the casing 100, thus lowering maintenance costs. In actual use, users will experience faster indoor air renewal and more noticeable cooling or heating effects, providing a better user experience.

[0093] Optionally, the first reinforcing rib 161 may not be provided.

[0094] In the optional implementation of the above-mentioned portable air conditioner, the outdoor air inlet 122 includes a plurality of outdoor air inlet holes 1220 formed on the outer casing 100; the inner side of the outer casing 100 is provided with a plurality of cross-connected second reinforcing ribs 162; the second reinforcing ribs 162 are arranged to avoid the outdoor air inlet holes 1220.

[0095] The design of multiple outdoor air inlets 1220 increases the air intake area, which helps ensure the flow rate of air entering the outdoor cavity 112, thereby improving the efficiency of indoor air circulation and heat exchange. The cross-connection of the second reinforcing ribs 162 further enhances the structural strength of the outer shell 100 in the outdoor air intake area, and can better resist possible external collisions and compression. At the same time, the arrangement of the outdoor air inlets 1220 ensures that outdoor air can smoothly enter through the outdoor air inlets 1220, making outdoor air circulation smoother.

[0096] This not only helps improve the overall performance of the portable air conditioner, but also effectively reduces the increased energy consumption caused by poor airflow. During long-term use, stable airflow helps extend the lifespan of internal components, further reducing operating costs and maintenance frequency.

[0097] The cross-connection of the second reinforcing rib 162 further enhances the structural strength of the outer casing 100 in the outdoor air intake area, better resisting possible external impacts and compression. Simultaneously, the arrangement that avoids the outdoor air intake 1220 ensures that outdoor air can smoothly enter through it, resulting in smoother outdoor air circulation. This not only helps improve the overall performance of the portable air conditioner but also effectively reduces energy consumption caused by poor air intake. During long-term use, stable air intake helps extend the lifespan of the internal components, further reducing operating costs and maintenance frequency.

[0098] Optionally, the second reinforcing rib 162 may not be provided.

[0100] Alternatively, the indoor heat exchanger 710 can be configured as a bent connection between the first and second indoor heat exchange sections to increase the heat exchange capacity of the indoor heat exchanger 710. Correspondingly, two indoor air inlets 121 are constructed on the two side plates of the outer casing 100 to increase the air intake. Thus, the mounting side plate 130 is located between the two indoor air inlets 121, and two filter sections 300 are also provided accordingly. To reduce the complexity of the connection structure between the two filter sections 300 and the mounting side plate 130, a transition opening is provided on the connecting plate 312 of one of the filter sections 300, which matches the first snap-fit ​​410; a buckle 420 is provided on the connecting plate 312 of the other filter section 300, which passes through the transition opening and engages with the first snap-fit ​​410, thereby fixing the two filter sections 300.

[0103] Alternatively, the outdoor heat exchanger 730 can be configured as a first outdoor heat exchange section and a second outdoor heat exchange section connected by a bend. Correspondingly, two outdoor air inlets 122 are constructed on the two side plates of the outer casing 100. Thus, the mounting side plate 130 is located between the two outdoor air inlets 122, and two filter sections 300 are also provided accordingly. To reduce the complexity of the connection structure between the two filter sections 300 and the mounting side plate 130, a transition opening is provided on the connecting plate 312 of one of the filter sections 300, which matches the first snap-fit ​​410; a buckle 420 is provided on the connecting plate 312 of the other filter section 300, which passes through the transition opening and engages with the first snap-fit ​​410, thereby fixing the two filter sections 300.
