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 require fixed installation in a limited location and cannot be moved. Therefore, portable air conditioners have emerged, primarily consisting 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 outdoor air inlets and outlets corresponding to the outdoor airflow assembly. Due to their small size, portable air conditioners can be moved to different locations or rooms to regulate the air temperature in those locations or rooms.

[0003] In a portable air conditioner of related technology, there is an outer shell forming an indoor heat exchange chamber and an indoor fan disposed in the indoor heat exchange chamber. The top plate of the outer shell has an indoor air outlet corresponding to the indoor heat exchange chamber. The indoor fan includes a first volute and a second volute that interlock with each other. The air outlet of the fan, constructed by the first and second volutes, also has a first air outlet section and a second air outlet section respectively. The first and second air outlet sections are interconnected and interlocked, and extend toward the top plate for fixed connection with the top plate. An air outlet channel is enclosed between the first and second air outlet sections, located between the indoor air outlet and the fan outlet. However, because there is a gap between the first and second air outlet sections, not only is a discontinuity easily caused when installing and fitting with the outer parts, but the air outlet effect of the air outlet channel is also easily affected. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problem, namely, the problem of air leakage in the air outlet section of the indoor fan.

[0005] This utility model provides a portable air conditioner, comprising: a shell, which internally defines an indoor cavity, the shell including a top cover corresponding to the indoor cavity; an indoor air outlet, which is opened on the top cover corresponding to the indoor cavity; an indoor fan, disposed in the indoor cavity, including at least a first volute and a second volute that are engaged with each other, the top ends of the first volute and the second volute respectively forming a first opening and a second opening, the first opening and the second opening together constituting the fan outlet; and an air outlet frame, integrally formed and enclosing an air outlet channel, the first end of the air outlet frame being configured to match the fan outlet and to connect with the first volute and the second volute; the second end of the air outlet frame being configured to match the indoor air outlet and to be detachably connected to the top cover.

[0006] By adopting the above technical solution, the presence of gaps can be avoided by setting an integrally molded air outlet frame. At the same time, the first end of the air outlet frame is connected to the first and second volutes, and the second end of the air outlet frame is detachably connected to the top cover. This can prevent leakage of airflow from the fan outlet to the indoor air outlet, thereby ensuring that all the airflow from the fan outlet flows to the indoor air outlet through the air outlet channel, thus avoiding airflow loss and improving the air outlet effect.

[0007] In the optional implementation of the above-mentioned portable air conditioner, a docking assembly is further included. The docking assembly includes: a docking step portion, which is formed circumferentially around the fan outlet in the first volute and the second volute, including a vertical step plate and a horizontal step plate connected in sequence, the horizontal step plate extending toward the fan outlet and configured to abut against the lower end face of the first end; and a mounting rib, which is arranged circumferentially around the first end on the outer circumferential surface of the air outlet frame and configured to abut against the vertical step plate.

[0008] The docking components facilitate the docking installation of the air outlet frame with the first and second volutes. At the same time, the cooperation between the docking step and the mounting rib prevents airflow leakage from the connection between the first and second volutes and the air outlet frame, thereby improving the air outlet effect and avoiding airflow loss.

[0009] In an optional embodiment of the above-mentioned bottom portable air conditioner, the horizontal step plate includes a vertical step surface facing the inside of the fan outlet, and the inner circumferential surface of the air outlet frame is arranged flush with the vertical step surface.

[0010] By arranging the inner circumferential surface of the air outlet frame flush with the vertical step surface, it is possible to avoid creating dead zones in airflow due to corners and reduce airflow resistance. On the other hand, it facilitates assembly and maintenance, maintains consistency between the inner surfaces of the air outlet frame and the first and second volutes, and improves aesthetics.

[0012] By using the clamping gap and cooperating with the first frame plate, it is easy to position and fix the air outlet frame, and the structure is simple, making it easy to assemble the air outlet frame.

[0013] In the optional implementation of the above-mentioned bottom portable air conditioner, multiple sets of connecting components are also included. The connecting components include: a first buckle, which is disposed on the mounting rib corresponding to the first arc-shaped housing and the second volute; and a first locking block, which is disposed on the outer surface of the vertical step plate in cooperation with the first buckle.

[0014] The engagement of the first buckle and the first locking block facilitates the connection between the first arc-shaped housing and the second volute housing and the air outlet frame, ensuring the assembly of the air outlet frame with the first and second volute housings.

[0015] In the optional implementation of the above-mentioned bottom portable air conditioner, the second volute includes: a baffle plate, which is arranged opposite to the air inlet side plate; a second arc-shaped shell, which is fixed to the inner side of the baffle plate and is fastened and snapped with the first arc-shaped shell, and the top end of the second arc-shaped shell has a second opening; wherein, the second arc-shaped shell and the first arc-shaped shell are also fixedly connected to the fan outlet near the fan outlet by a connector.

[0016] By fixing the second arc-shaped housing to the first arc-shaped housing near the fan outlet using a connector, the stability and tightness of the connection between the first and second volutes can be improved, and the gap between them can be reduced.

[0017] In an optional embodiment of the above-mentioned bottom-mounted air conditioner, the first frame plate includes: a retaining section extending vertically and configured to be accommodated in the retaining gap; and an inclined section extending upward from the retaining section in a direction away from the air inlet side plate, the inclined section being configured to engage with the top cover.

[0018] By setting the inclined section, the stability of the connection between the first frame plate and the air inlet side plate and the top cover can be improved; the inclined arrangement of the inclined section can create a clearance space for the clamping section, so as to facilitate the clamping connection with the air inlet side plate, and avoid interference between the limiting part, the clamping section and the top cover, thereby improving the stability of the assembly; in addition, the inclined section can guide the airflow toward the indoor air outlet.

[0019] In the optional implementation of the above-mentioned bottom portable air conditioner, the limiting component includes a limiting hook, and the holding section is provided with a limiting block or limiting groove that cooperates with the limiting hook.

[0020] The combination of the limit hook and the limit block / limit groove has a simple structure that allows for quick installation, improving installation efficiency while ensuring structural stability.

[0021] In the optional implementation of the above-mentioned bottom portable air conditioner, a snap-fit ​​assembly is further included. The snap-fit ​​assembly includes: a second snap fastener, disposed on the side end of the inclined section away from the holding section; and a second snap block, disposed on the periphery of the indoor air outlet corresponding to the second snap fastener, and configured to snap-fit ​​with the second snap fastener.

[0022] The first buckle and the second locking block ensure a secure connection between the inclined section and the top cover, thus improving stability.

[0023] In an optional embodiment of the above-mentioned bottom portable air conditioner, a limiting component is included, the limiting component comprising: a limiting step portion formed around the circumferential end edge of the second end and recessed toward the interior of the air outlet frame; and a limiting plate circumferentially arranged around the indoor air outlet and on the inner side of the top cover, the limiting plate extending toward the indoor cavity and configured to abut against the limiting step portion.

[0024] The cooperation between the limiting step and the limiting plate ensures the fit between the second end and the top cover, and keeps the air outlet frame between the top cover and the first and second volutes, ensuring the stability of the air outlet frame assembly. In addition, the cooperation between the limiting step and the limiting plate prevents air leakage, improves the air outlet effect, and thus avoids airflow loss. Attached Figure Description

[0041] Combination Figures 1 to 10 As shown, this utility model provides a portable air conditioner, including a housing 100, an indoor air outlet 111, an indoor fan 200, and an air outlet frame 300.

[0042] The outer casing 100 defines an inner cavity 101, and includes a top cover 110 corresponding to the inner cavity 101. An indoor air outlet 111 is formed on the top cover 110. An indoor fan 200 is disposed in the inner cavity 101, and includes at least a first volute 210 and a second volute 220 that are engaged with each other. The top ends of the first volute 210 and the second volute 220 are respectively formed with a first opening 211 and a second opening 221, which together constitute the fan outlet 201. An air outlet frame 300 is integrally formed and encloses an air outlet channel. The first end 310 of the air outlet frame 300 is configured to match the fan outlet 201 and to connect with the first volute 210 and the second volute 220; the second end 320 of the air outlet frame 300 is configured to match the indoor air outlet 111 and is detachably connected to the top cover 110.

[0043] Optionally, the outer casing 100 internally defines two independent indoor cavities 101 and 102. In this design, the indoor cavity 101 houses an indoor fan 200 and an indoor heat exchanger, while the outdoor cavity 102 houses an outdoor fan and an outdoor heat exchanger. The indoor cavity 101 and outdoor cavity 102 are arranged vertically. Thus, the indoor air outlet 111 corresponding to the indoor cavity 101 is located on the top cover 110 of the outer casing 100 to facilitate the supply of air to the indoor cavity for heat exchange with the indoor heat exchanger. Furthermore, the outer casing 100 has an outdoor air inlet and an outdoor air outlet corresponding to the outdoor cavity 102, allowing air to enter the outdoor cavity 102 under the drive of the outdoor fan to exchange heat with the outdoor heat exchanger, thereby ensuring the flow of refrigerant between the indoor and outdoor heat exchangers.

[0044] Optionally, the outer casing 100 is also provided with an indoor air inlet corresponding to the indoor cavity 101, and the indoor fan 200 is located on the path from the indoor air inlet to the indoor air outlet 111. The indoor fan 200 includes at least a first volute 210 and a second volute 220 that interlock with each other. The first volute 210 and the second volute 220 together enclose an installation space, and the impeller 230 of the indoor fan 200 is disposed within the installation space. The top of the indoor fan 200 is provided with a fan outlet 201 to correspond to the indoor air outlet 111, thereby reducing the length of airflow, reducing flow loss, and improving airflow fluidity.

[0045] Optionally, to ensure sufficient airflow from the fan outlet 201 to the indoor air outlet 111, an integrally formed air outlet frame 300 is provided at the fan outlet 201, with an air outlet channel defined within the frame 300. This avoids gaps in the side walls of the air outlet frame 300, preventing air leakage in the air outlet channel and ensuring that all airflow from the fan outlet 201 flows through the air outlet channel to the indoor air outlet 111, minimizing airflow loss and improving airflow efficiency.

[0046] Optionally, the first end 310 of the air outlet frame 300 is configured to match the fan outlet 201 and connect with the first volute 210 and the second volute 220; the second end 320 of the air outlet frame 300 is configured to match the indoor air outlet 111 and be detachably connected to the top cover 110. This ensures a stable transition flow of air from the indoor fan 200 to the air outlet duct, and from the air outlet duct to the indoor air outlet 111, avoiding turbulence and eddies during the transition flow, thereby improving airflow efficiency and reducing flow noise and vibration. The detachable connection can be a snap-fit, plug-in, or other connection method.

[0047] By adopting the above technical solution, the presence of gaps can be avoided by setting an integrally molded air outlet frame 300. At the same time, the first end 310 of the air outlet frame 300 is connected to the first volute 210 and the second volute 220, and the second end 320 of the air outlet frame 300 is detachably connected to the top cover 110. This can prevent leakage of airflow from the fan outlet 201 to the indoor air outlet 111, thereby ensuring that all the airflow from the fan outlet 201 flows to the indoor air outlet 111 through the air outlet channel, thus avoiding airflow loss and improving the air outlet effect.

[0048] In an optional embodiment of the aforementioned portable air conditioner, a docking assembly 400 is further included. The docking assembly 400 includes a docking step portion 410 and a mounting rib 420. The docking step portion 410 is formed circumferentially around the fan outlet 201 in the first volute 210 and the second volute 220, and includes a vertical step plate 411 and a horizontal step plate 412 connected in sequence. The horizontal step plate 412 extends toward the fan outlet 201 and is configured to abut against the lower end face of the first end 310. The mounting rib 420 is arranged circumferentially around the first end 310 on the outer peripheral surface of the air outlet frame 300 and is configured to abut against the vertical step plate 411.

[0049] The docking component 400 facilitates the docking and installation of the air outlet frame with the first volute 210 and the second volute 220. At the same time, the cooperation between the docking step 410 and the mounting rib 420 can prevent airflow leakage from the connection between the first volute 210 and the second volute 220 and the air outlet frame 300, thereby improving the air outlet effect and avoiding airflow loss.

[0050] Optionally, the surface of the vertical step plate 411 facing the fan outlet 201 abuts against the outer periphery of the air outlet frame 300, and the top surface of the vertical step plate 411 abuts against the lower surface of the mounting rib 420.

The first arc-shaped housing 213 is fixed to the inner side of the air inlet side plate 212 and has a first opening 211 formed at its top. The limiting member 214 is disposed at the top of the air inlet side plate 212 and extends toward the first opening 211. A retaining gap is formed between the limiting member 214 and the supporting step 215, and the retaining gap is configured to at least clamp a portion of the first frame plate 330.

[0058] The engagement between the clamping gap and the first frame plate 330 facilitates the positioning and fixing of the air outlet frame 300, and the simple structure makes it easy to assemble the air outlet frame 300.

[0059] Optionally, the inner side of the air inlet side plate 212 is the side facing the second volute 220.

[0060] Optionally, multiple limiting members 214 are provided at intervals along the length of the air inlet side plate 212.

The second arc-shaped housing 223 and the first arc-shaped housing 213 are also fixedly connected near the fan outlet 201 by a connector.

[0072] By fixing the second arc-shaped housing 223 to the first arc-shaped housing 213 near the fan outlet 201 using a connector, the stability and tightness of the connection between the first volute 210 and the second volute 220 can be improved, reducing the gap between them. Specifically, the connector is a screw, or a pin. Alternatively, the connector can be any other cylindrical structure.

[0073] Optionally, one of the first arc-shaped housing 213 and the second arc-shaped housing 223 is provided with a threaded groove 241, and the other is provided with a corresponding through hole 242.
