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. Portable air conditioners mainly consist of a casing, an indoor airflow assembly, and an outdoor airflow assembly. The indoor and outdoor airflow assemblies are both housed within the casing. The casing has indoor air inlets and outlets corresponding to the indoor airflow assembly, and it also has outdoor air inlets and outlets corresponding to the outdoor airflow assembly.

[0003] In portable air conditioners of this technology, the evaporator is located on the top and the condenser on the bottom. To improve heat exchange efficiency, the condensate produced by the evaporator is collected in a drip tray, and a drain hole corresponding to the condenser is provided on the drip tray to cool the condenser. Because the condensate can splash and pose a safety hazard as it drips, a water collection box is installed above the condenser. However, the dripping of condensate into the collection box produces a dripping sound, increasing the noise level of the portable air conditioner during operation and affecting the user experience. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the noise problem caused by dripping water when the portable air conditioner is running.

[0005] This utility model provides a portable air conditioner, comprising: a shell with an internal cavity; an outdoor air duct assembly separating the cavity into an indoor cavity and an outdoor cavity distributed vertically, the outdoor air duct assembly including an upper air duct plate, a lower air duct plate, and a volute, the upper air duct plate having a water receiving space for an indoor heat exchanger; a drain pipe connecting to the water receiving space and disposed on the upper air duct plate, the drain pipe extending toward the lower air duct plate; a water collection box formed on the lower air duct plate corresponding to the drain pipe and located outside the volute, wherein the drain pipe extends into the interior of the water collection box; and a water distribution component disposed on the lower air duct plate and extending toward the upper air duct plate, the water distribution component being located inside the water collection box, the water distribution component being configured to allow condensate flowing from the drain pipe to flow along its own surface toward the air duct plate.

[0006] When the portable air conditioner is in cooling mode using the above technical solution, the indoor heat exchanger absorbs heat from the passing air to form low-temperature air. Consequently, condensation forms on the surface of the indoor heat exchanger and flows into the water collection space. The condensation in the water collection space flows out through the drain pipe and then flows towards the water distribution component towards the lower air duct plate. The water distribution component diverts the condensation and guides it downwards along its surface into the water collection box. This prevents the condensation from dripping directly to the bottom of the water collection box, creating a loud dripping sound. Instead, it flows smoothly to the bottom, significantly reducing dripping noise and improving user comfort and experience.

[0007] In an optional embodiment of the above-mentioned portable air conditioner, the water distribution component includes: a first stiffener extending along a first direction; and a second stiffener extending along a second direction and intersecting with the first stiffener, wherein the connector formed by the intersection of the first stiffener and the second stiffener is at least partially located within the projection area of ​​the drain pipe on the lower air duct plate.

[0008] By setting up a water distribution component formed by the intersection of the first and second stiffeners, the condensate flowing out of the drain pipe can be better distributed on the water distribution component. That is, the water distribution component can disperse the water flow, allowing the condensate to flow along the surfaces of the first and second stiffeners in different directions, and then flow smoothly into the water collection box, avoiding the water flow from dripping in a concentrated manner and generating a lot of noise.

[0009] In the optional embodiment of the above-mentioned portable air conditioner, the thickness of the first stiffener and the second stiffener are both in the range of 1mm to 5mm; the height of the first stiffener and the second stiffener is less than the distance from the lower end face of the drain pipe near the water distribution component to the lower air duct plate.

[0010] By setting the thickness of the first and second stiffening plates within the range of 1mm to 5mm, sufficient strength to support the flow of condensate water is ensured without excessive space occupation due to excessive thickness. Setting the height of the first and second stiffening plates to be less than the distance from the lower end of the drain pipe near the water distribution component to the lower air duct plate ensures that condensate water can flow smoothly along the surfaces of the first and / or second stiffening plates to the bottom of the water collection box, without obstructing the flow due to excessive height of the stiffening plates. Furthermore, appropriate thickness and height settings also help reduce production costs and simplify the manufacturing process, improving the overall performance and market competitiveness of the product.

[0011] In an optional embodiment of the above-described portable air conditioner, the end of the first stiffener near the drain pipe is configured as a tapered end; and / or, the end of the second stiffener near the drain pipe is configured as a tapered end.

[0012] Setting the end of the first and / or second stiffeners near the drain pipe as a tapered end can better divert the condensate flowing out of the drain pipe, prevent condensate from accumulating at this end of the first and / or second stiffeners near the drain pipe, ensure that the condensate can flow smoothly along the surface of the stiffeners to the bottom of the collection box, further reduce splashing and noise generated during the diversion process, and improve the stability and effectiveness of the entire drainage noise reduction system.

[0013] In an optional embodiment of the above-mentioned portable air conditioner, the side surface of the first stiffener is provided with a plurality of spaced first guide ribs, the first guide ribs extending along the height direction of the first stiffener; and / or, the side surface of the second stiffener is provided with a plurality of spaced second guide ribs, the second guide ribs extending along the height direction of the second stiffener.

[0014] By incorporating the first and / or second guide ribs, the flow path of condensate in the water distribution component can be optimized. When condensate flows along the first or second rib, the guide ribs divide the water flow into multiple smaller streams, increasing the contact area between the water and the surface of the first or second rib, thereby slowing down the flow velocity. Simultaneously, the spaced arrangement of the guide ribs ensures a more even distribution of the water flow across the surface of the first or second rib, preventing concentrated flow from generating significant noise.

[0015] In the optional implementation of the above-mentioned portable air conditioner, the water distribution component further includes: a first guide plate, which is respectively disposed on two side ends of the first rib in a first direction and is fixedly connected to the lower air duct plate; and a second guide plate, which is respectively disposed on two side ends of the second rib in a second direction and is fixedly connected to the lower air duct plate.

[0016] The placement of the first and second guide plates further optimizes the flow distribution effect of the water distributor. The first guide plate further diverts and guides the condensate flowing along the first rib to the downwind duct plate, preventing splashing of condensate from the side of the first rib and ensuring a smooth, level flow into the collection box. Similarly, the second guide plate provides the same guidance for the condensate flowing along the second rib. Furthermore, the fixed connection between the first and second guide plates and the downwind duct plate enhances the overall stability of the water distributor. This not only ensures the continuous and stable function of the water distributor in diverting and guiding the flow but also reduces additional noise that may be generated due to the shaking of the water distributor.

[0017] In the optional implementation of the above-mentioned portable air conditioner, the thickness of the first guide plate and the second guide plate is both in the range of 1mm to 5mm; the height of the first guide plate and the second guide plate is both less than the distance from the lower end face of the drain pipe near the water distribution component to the lower air duct plate.

[0018] This design ensures that the first and second guide plates have sufficient structural strength to effectively guide condensate while avoiding excessive thickness that could impede its flow. Furthermore, setting the height of the first and second guide plates to be less than the distance from the lower end of the drain pipe near the water distribution component to the lower air duct plate ensures that condensate can flow smoothly along the surfaces of the first and / or second guide plates to the bottom of the collection box, without obstructing the flow due to excessive height. In addition, the reasonable thickness and height settings also help reduce manufacturing material costs and improve the product's economic efficiency.

[0019] In the above-described optional implementation of the portable air conditioner, the distance between the two first air guide plates gradually increases from top to bottom; and / or, the distance between the two second air guide plates gradually increases from top to bottom.

[0020] By arranging the two first guide vanes and / or the two second guide vanes in a configuration where the distance between them gradually increases from top to bottom, the flow of condensate in the water distribution component can be optimized. This arrangement allows the condensate to flow downwards in a more dispersed manner as it flows along the first rib to the first guide vane, or along the second rib to the second guide vane. This dispersed flow avoids the large impact force generated by concentrated water flow, thereby reducing noise generated when the condensate collides with the lower air duct plate at the bottom of the collection box or the water surface.

[0021] In an optional embodiment of the above-mentioned portable air conditioner, the drain pipe is arranged at an angle relative to the lower air duct plate near the lower end face of the water distribution component; and / or, the diameter of the drain pipe gradually decreases from top to bottom.

[0022] By arranging the drain pipe at an angle relative to the lower air duct plate, the lower end face of the drain pipe is close to the water distributor. This allows the condensate to flow towards the water distributor at an angle as it exits the drain pipe. This arrangement ensures that the condensate has a certain horizontal velocity component before contacting the water distributor, allowing it to fall more dispersedly onto the water distributor and avoiding concentrated dripping that would generate significant impact and noise.

[0023] By designing the drain pipe with a gradually decreasing diameter from top to bottom, the flow velocity of condensate within the drain pipe can be increased, reducing its residence time and the probability of noise caused by condensate buildup. Simultaneously, when the condensate flows out of the drain pipe at a faster speed, it is more effectively dispersed upon impact with the water distribution element, minimizing the noise generated by concentrated dripping.

[0024] In the optional implementation of the above-mentioned portable air conditioner, it further includes: an outdoor heat exchanger disposed in the outdoor cavity, and the outdoor heat exchanger is arranged at least partially corresponding to the water collection box; wherein, the lower air duct plate is provided with water distribution holes, and the condensate in the water collection box drips onto the surface of the outdoor heat exchanger through the water distribution holes.

[0025] By incorporating water distribution holes, the condensate in the water collection box drips onto the surface of the outdoor heat exchanger, effectively reducing the temperature of the outdoor heat exchanger. This improves the utilization rate of the condensate's cooling capacity and enhances the heat exchange efficiency of the outdoor heat exchanger. Furthermore, this method ensures full utilization of the condensate in the water collection box, reducing the possibility of excessive condensate accumulation and mitigating potential safety hazards caused by overflow. Ultimately, this improves the safety and reliability of the portable air conditioner during operation. Attached Figure Description

[0042] Combination Figures 1 to 10 As shown, this utility model provides a portable air conditioner, including: a shell 100, an outdoor air duct assembly 200, a drain pipe 240, a water collection box 400, and a water distribution component 250.

[0043] The interior of the outer casing 100 forms a cavity. The outdoor air duct assembly 200 divides the cavity into an indoor cavity 101 and an outdoor cavity 102, which are distributed vertically. The outdoor air duct assembly 200 includes an upper air duct plate 210, a lower air duct plate 220, and a volute 230. The upper air duct plate 210 has a water receiving space 2101 for the indoor heat exchanger 310. A drain pipe 240 connects to the water receiving space 2101 and is disposed on the upper air duct plate 210, extending towards the lower air duct plate 220. A water collection box 400 is formed on the lower air duct plate 220 corresponding to the drain pipe 240 and is located outside the volute 230, wherein the drain pipe 240 extends into the interior of the water collection box 400. The water distribution component 250 is disposed on the lower air duct plate 220 and extends toward the upper air duct plate 210, corresponding to the drain pipe 240. The water distribution component 250 is located in the water collection box 400 and is configured to allow the condensate flowing out of the drain pipe 240 to flow down its own surface toward the lower air duct plate 220.

[0044] Optionally, the outer casing 100 has an internal cavity, within which an outdoor air duct assembly 200 is disposed, separating the cavity into an indoor cavity 101 and an outdoor cavity 102 distributed vertically. Specifically, the outdoor air duct assembly 200 includes an upper air duct plate 210, a lower air duct plate 220 arranged opposite to each other, and a volute 230 disposed between the upper air duct plate 210 and the lower air duct plate 220. The upper air duct plate 210, the lower air duct plate 220, and the volute 230 together enclose a receiving cavity, within which a fan is disposed. The outdoor air duct assembly 200 connects to the outdoor cavity 102, which contains an outdoor heat exchanger 320. The fan drives air into the outdoor cavity 102, where it exchanges heat with the outdoor heat exchanger 320 before flowing through the outdoor air duct assembly 200 to the outside.

[0045] Optionally, the upper air duct plate 210 faces the indoor cavity 101, which houses an indoor heat exchanger 310 and an indoor fan. The indoor fan drives indoor air into the indoor cavity 101, where it exchanges heat with the indoor heat exchanger 310 before entering the indoor environment to regulate the indoor temperature. The outer casing 100 has indoor air inlets and outlets corresponding to the indoor cavity 101, and outdoor air inlets and outlets corresponding to the outdoor cavity 102; the volute 230 has an air outlet corresponding to the outdoor outlet; and the lower air duct plate has an air inlet connecting the receiving cavity and the outdoor cavity 102.

[0046] In this design, when the portable air conditioner is in cooling mode, the indoor heat exchanger 310 acts as the evaporator and the outdoor heat exchanger 320 acts as the condenser.

[0047] Optionally, the indoor heat exchanger 310 is a multi-section heat exchanger with bent connections, such as an L-shaped heat exchanger, a U-shaped heat exchanger, or L-shaped heat exchangers arranged end to end. Correspondingly, the water receiving space 2101 matches the shape of the indoor heat exchanger 310.

[0048] Optionally, the volute 230 and the downdraft duct 220 are integrally formed.

[0049] Alternatively, the volute 230 and the upper air duct 210 are integrally formed.

[0050] Optionally, the indoor heat exchanger 310 is installed on the upper air duct plate 210. When the indoor heat exchanger 310 is cooling, it produces a large amount of condensate. Therefore, a water collection space 2101 for collecting the condensate is constructed on the upper air duct plate 210. Optionally, a drain connector 270 is provided on the upper air duct plate 210, and the drain connector 270 is configured to be detachably connected to an external water outlet pipe. Optionally, when the amount of condensate is large, it needs to be discharged through the external water outlet pipe. Furthermore, it is also discharged into the water collection box 400 through the drain pipe 240.

[0051] Optionally, when the external water outlet pipe is disconnected, a drain cap is screwed onto the drain connector.

[0052] Optionally, the water collection box 400 is formed on the lower air duct plate 220 and located outside the volute 230. This avoids problems such as condensation causing corrosion of the impeller and other components inside the housing cavity.

[0053] Optionally, the water collection box 400 and the downdraft duct plate 220 are integrally formed.

[0054] Optionally, a water distribution element 250 is provided on the downdraft duct plate 220 corresponding to the drain pipe 240. Due to the water distribution element 250, the condensate flowing out of the drain pipe 240 can be diverted, and the diverted condensate flows downdraft duct plate 220 through the surface of the water distribution element 250. This prevents a large amount of condensate from directly impacting the downdraft duct plate 220 corresponding to the water collection box 400, or the water surface within the water collection box 400. The condensate flows into the water collection box 400 in a more gradual manner, thereby reducing or even eliminating noise.

[0055] Optionally, the water distribution component 250 and the downdraft duct plate 220 are integrally formed.

[0056] Optionally, the height of the water distribution component 250 should be higher than the highest set water level in the water collection box 400. Optionally, a liquid level detection device is installed in the water collection box 400. If the water level in the water collection box 400 is higher than the highest set water level, the liquid level detection device sends feedback information to the control module of the portable air conditioner to prompt the user to install an external water outlet pipe at the drain connector 270 to reduce the amount of condensate entering the water collection box 400. Further, the height of the water distribution component 250 is less than the distance from the lower end face of the drain pipe 240 towards the lower air duct plate 220 to the lower air duct plate 220.

[0057] Optionally, a plurality of reinforcing ribs 241 are provided around the circumference of the drain pipe 240, and the reinforcing ribs 241 are located at the bend connection between the drain pipe 240 and the upper air duct plate 210. This can improve the structural strength of the drain pipe 240. Furthermore, the reinforcing ribs 241 extend along the length of the drain pipe 240.

[0058] Optionally, a plurality of circumferential reinforcing ribs 241 are evenly arranged around the drain pipe 240.

[0059] When the portable air conditioner is in cooling mode using the above technical solution, the indoor heat exchanger absorbs heat from the flowing air to form low-temperature air. Simultaneously, condensation forms on the surface of the indoor heat exchanger and flows into the water collection space. The condensation in the water collection space flows out through the drain pipe and then flows towards the water distribution component towards the lower air duct plate. The water distribution component diverts the condensation and guides it downwards along its surface into the water collection box. In this way, the condensation does not drip directly to the bottom of the water collection box, producing a loud dripping sound, but rather flows to the bottom of the water collection box in a more gentle manner, thus greatly reducing dripping noise, lowering flow noise, and improving user comfort and experience.

[0060] In an optional embodiment of the portable air conditioner described above, the water distribution component 250 includes a first stiffener 251 and a second stiffener 252. The first stiffener 251 extends along a first direction. The second stiffener 252 extends along a second direction and intersects with the first stiffener 251. The connection formed by the intersection of the first stiffener 251 and the second stiffener 252 is at least partially located within the projection area of ​​the drain pipe 240 on the lower air duct plate 220.

[0061] In this scheme, the first direction is the width direction of the water collection box 400, and the second direction is the length direction of the water collection box 400.

[0062] By setting up a water distribution component formed by the intersection of the first stiffener 251 and the second stiffener 252, the condensate flowing out of the drain pipe 240 can be better distributed on the water distribution component 250. That is, the water distribution component 250 can disperse the water flow, allowing the condensate to flow along the surfaces of the first stiffener 251 and the second stiffener 252 in different directions, and then flow smoothly into the water collection box 400, avoiding the water flow from dripping in a concentrated manner and generating a large amount of noise.

[0063] Furthermore, the cross-connection of the first stiffener 251 and the second stiffener 252 can slow down the flow of condensate while dispersing it, allowing the condensate to flow more smoothly into the upper air duct plate 210 at the bottom of the water collection box 400.

[0064] Furthermore, the cross arrangement of the first stiffener 251 and the second stiffener 252 enhances the structural stability of the water distribution component 250. This ensures that the water distribution component 250 maintains good water distribution performance and stability even under long-term condensate impact, and continuously and effectively reduces drainage noise.

[0065] Optionally, the included angle between the first stiffening plate 251 and the second stiffening plate 252 is 90°.

[0066] Alternatively, the angle between the first stiffener 251 and the second stiffener 252 may be less than or greater than 90°.

[0067] Alternatively, the first direction is the direction in which the water collection box 400 is arranged at an angle greater than 0° with the width direction; the second direction is the direction in which the water collection box 400 is arranged at an angle greater than 0° with the length direction.

[0068] Optionally, the connector formed by the intersection of the first stiffener 251 and the second stiffener 252 is at least partially located within the projection area of ​​the drain pipe 240 on the downwind duct plate 220. This ensures that the condensate flowing out of the drain pipe 240 can fall onto the water distribution member 250, thereby ensuring the diversion effect of the condensate and improving the noise reduction effect.

[0069] Optionally, the thickness of the first stiffener 251 and the second stiffener 252 is equal.

[0070] Optionally, the thickness of the first stiffener 251 is less than the radius of the drain pipe 240; and the thickness of the second stiffener 252 is less than the radius of the drain pipe 240.

[0071] In the above-mentioned optional embodiment of the portable air conditioner, the thickness of the first stiffener 251 and the second stiffener 252 is both in the range of 1mm to 5mm; the height of the first stiffener 251 and the second stiffener 252 is both less than the distance from the lower end face of the drain pipe 240 near the water distribution component 250 to the lower air duct plate 220.

[0072] Optionally, the thickness of the first stiffening plate 251 is 1mm to 5mm; the thickness of the second stiffening plate 252 is 1mm to 5mm. Specifically, the thickness of the first stiffening plate 251 is set to 1.2mm, and the thickness of the second stiffening plate 252 is set to 1.2mm. Optionally, the thickness of the first stiffening plate 251 and the thickness of the second stiffening plate 252 are determined according to actual needs.

[0073] Optionally, the height of the first stiffener 251 and the first stiffener 251 are both in the range of 15mm to 35mm. Preferably, the height of the first stiffener 251 is set to 21mm.

[0074] By setting the thickness of the first stiffener 251 and the second stiffener 252 within the range of 1mm to 5mm, sufficient strength to support the flow of condensate water is ensured without taking up too much space due to excessive thickness. Furthermore, setting the height of the first stiffener 251 and the second stiffener 252 to be less than the distance from the lower end face of the drain pipe 240 near the water distribution component 250 to the lower air duct plate 220 ensures that condensate water can flow smoothly along the surface of the first stiffener 251 and / or the second stiffener 252 to the lower air duct plate 220 at the bottom of the water collection box 300, without obstructing the water flow due to excessive height of the first stiffener 251 and / or the second stiffener 252.

[0075] In addition, setting appropriate thicknesses and heights for the first stiffener 251 and the second stiffener 252 helps reduce production costs, simplify manufacturing processes, and improve the overall performance and market competitiveness of the product.

[0076] In an optional embodiment of the above-described portable air conditioner, the end of the first stiffener 251 near the drain pipe 240 is configured as a tapered end; and / or, the end of the second stiffener 252 near the drain pipe 240 is configured as a tapered end.

[0077] By setting the end of the first stiffener 251 and / or the second stiffener 252 near the drain pipe 240 as a tapered end, the condensate flowing out of the drain pipe 240 can be better diverted. The condensate accumulates at this end of the first stiffener 251 and / or the second stiffener 252 near the drain pipe 240, ensuring that the condensate can flow smoothly along the surface of the first stiffener 251 and / or the second stiffener 252 to the bottom of the water collection box 400, further reducing the splashing and noise generated by the condensate during the diversion process.

[0078] Compared to a standard flat first stiffener 251, the end near the drain pipe 240 is designed with a tapered end; and / or, the end of the second stiffener 252 near the drain pipe 240 is also designed with a tapered end. The tapered end guides the condensate to form a more concentrated and finer water flow, reducing the noise generated by the scattered dripping water. Simultaneously, this arrangement prevents condensate from accumulating at the ends of the first stiffener 251 and / or the second stiffener 252 near the drain pipe 240, preventing excessive accumulation and sudden dripping that could produce a loud impact sound. Furthermore, the tapered end allows the water flow to transition more smoothly to the lower air duct plate 220 at the bottom of the water collection box 400, further reducing noise during the flow process and improving the user experience when using the portable air conditioner.

[0079] Alternatively, the end of the first stiffener 251 near the drain pipe 240 is configured as a flat end; and / or, the end of the second stiffener 252 near the drain pipe 240 is configured as a flat end.

[0080] Alternatively, the first stiffener 251 may have a plurality of spikes or a pointed protrusion at one end near the drain pipe 240; and / or the second stiffener 252 may have a plurality of spikes or a pointed protrusion at one end near the drain pipe 240.

[0081] In the optional implementation scheme of the aforementioned portable air conditioner, combined with Figure 9 , Figure 10 As shown, the side surface of the first stiffener 251 is provided with a plurality of spaced first guide ribs 255, which extend along the height direction of the first stiffener 251; and / or, the side surface of the second stiffener 252 is provided with a plurality of spaced second guide ribs 256, which extend along the height direction of the second stiffener 252.

[0082] By configuring the first guide rib 255 and / or the second guide rib 256, the flow path of the water distribution component 250 for condensate can be optimized. When condensate flows along the first rib 251, the first guide rib 255 can divide the water flow into multiple smaller streams, increasing the contact area between the water flow and the surface of the first rib 251, thereby slowing down the water flow velocity. Similarly, when condensate flows along the second rib 252, the second guide rib 256 can divide the water flow into multiple smaller streams, increasing the contact area between the water flow and the surface of the second rib 252, thereby slowing down the water flow velocity.

[0083] Meanwhile, the spaced arrangement of the first guide ribs 255 ensures a more even distribution of water flow on the surface of the first stiffener 251, preventing concentrated water flow from generating significant noise. Similarly, the spaced arrangement of the second guide ribs 256 ensures a more even distribution of water flow on the surface of the second stiffener 252, preventing concentrated water flow from generating significant noise. Moreover, the first guide ribs 255 or the second guide ribs 256 extending along the height direction of the first stiffener 251 or the second stiffener 252 can better guide the condensate downwards, reducing the residence time of water on the surface of the first stiffener 251 or the second stiffener 252, reducing the possibility of noise caused by water accumulation, and thus allowing the condensate to flow more smoothly into the water collection box 400.

[0084] In addition, the first guide rib 255 and the second guide rib 256 can also enhance the structural strength of the first stiffener 251 and the second stiffener 252, and improve the overall stability of the water distribution component 250.

[0085] Alternatively, the first guide rib 255 may not be provided, and / or the second guide rib 256 may not be provided.

[0086] In an optional embodiment of the aforementioned portable air conditioner, the water distribution component 250 further includes a first guide plate 253 and a second guide plate 254. The first guide plate 253 is respectively disposed on two side ends of the first stiffener 251 in a first direction and is fixedly connected to the lower air duct plate 220. The second guide plate 254 is respectively disposed on two side ends of the second stiffener 252 in a second direction and is fixedly connected to the lower air duct plate 220.

[0087] The arrangement of the first guide plate 253 and the second guide plate 254 further optimizes the flow guiding effect of the water distribution component 250. The first guide plate 253 can further divert and guide the condensate flowing along the first rib 251 to the downflow duct plate 220, preventing condensate from splashing from the side of the first rib 251 and ensuring that the condensate flows smoothly into the water collection box 400. Similarly, the second guide plate 254 plays the same guiding role for the condensate flowing along the second rib 252. Moreover, the first guide plate 253 and the second guide plate 254 are fixedly connected to the downflow duct plate 220, which enhances the overall stability of the water distribution component 250. This not only ensures that the water distribution component 250 can continuously and stably perform its diversion and guiding functions, but also reduces the additional noise that may be generated due to the shaking of the water distribution component 250.

[0088] Alternatively, the first deflector 253 may not be provided, and / or the second deflector 254 may not be provided.

[0089] In the optional implementation of the above-mentioned portable air conditioner, the thickness of the first guide plate 255 and the second guide plate 266 is both in the range of 1mm to 5mm; the height of the first guide plate 255 and the second guide plate is both less than the distance from the lower end face of the drain pipe near the water distribution component to the lower air duct plate.

[0090] Optionally, the thickness of the first guide vane 253 is 1mm to 5mm; the thickness of the second guide vane 254 is 1mm to 5mm. Specifically, the thickness of the first guide vane 253 is set to 1.2mm, and the thickness of the second guide vane 254 is set to 1.2mm. Optionally, the thickness of the first guide vane 253 and the thickness of the second guide vane 254 are determined according to actual needs.

[0091] Optionally, the height range of both the first guide vane 255 and the second guide vane 266 is 15mm to 35mm. Preferably, the height of the first guide vane 255 is set to 21mm, and the height of the second guide vane 266 is set to 21mm.

[0092] This design ensures that both the first guide plate 255 and the second guide plate 266 possess sufficient structural strength, effectively guiding condensate while avoiding excessive thickness that could impede its normal flow. Furthermore, setting the height of the first guide plate 255 and the second guide plate 266 to be less than the distance from the lower end face of the drain pipe 240 near the water distribution component 250 to the lower air duct plate 220 ensures that condensate can flow smoothly along the surfaces of the first guide plate 255 and / or the second guide plate 266 to the lower air duct plate 220 at the bottom of the water collection box 400, without obstructing the flow due to excessive height. In addition, the reasonable thickness and height of the first guide plate 255 and the second guide plate 266 also help reduce manufacturing material costs and improve the product's economic viability.

[0093] Optionally, the thickness of the first guide plate 253 and the second guide plate 254 is equal.

[0094] Optionally, the thickness of the first guide plate 253 is less than the radius of the drain pipe 240; and the thickness of the second guide plate 254 is less than the radius of the drain pipe 240.

[0095] Optionally, the thickness of the first guide plate 253 is equal to the thickness of the first stiffener 251; the thickness of the second guide plate 254 is equal to the thickness of the second stiffener 252.

[0096] In the above-mentioned optional implementation of the portable air conditioner, the distance between the two first air deflectors 253 gradually increases from top to bottom; and / or, the distance between the two second air deflectors 254 gradually increases from top to bottom.

[0097] By arranging the two first guide plates 253 and / or the second guide plates 254 in a manner that gradually increases in distance from top to bottom, the flow guidance process of the water distribution component 250 for condensate can be optimized. When condensate flows along the first rib 251 to the first guide plate 253, or along the second rib 252 to the second guide plate 254, this arrangement allows the condensate to flow more dispersedly downwards towards the lower air duct plate 220. This dispersed flow avoids the large impact force generated by concentrated water flow, thereby reducing noise generated when condensate collides with the lower air duct plate at the bottom of the water collection box or the water surface.

[0098] Meanwhile, as the dispersed water flows, the contact area and contact time with the first guide plate 253 and / or the second guide plate 254 increase, which helps to slow down the water flow and allows the condensate to flow more smoothly into the lower air duct plate 220 at the bottom of the water collection box 400. In addition, this structure can also increase the drainage capacity of the water distribution component to a certain extent, preventing overflow or splashing due to excessive water flow.

[0099] Alternatively, the two first deflector plates 253 are arranged in parallel and perpendicular to the downdraft plate 220, and / or the second deflector plate 254 is arranged in parallel and perpendicular to the downdraft plate 220.

[0100] Alternatively, the two first guide plates 253 are connected at one end near the drain pipe 240, and the two second guide plates 254 are connected at one end near the drain pipe 240, with the ends of the first guide plates 253 and the second guide plates 254 fixedly connected to form an integral conical end. In this case, the end of the first guide plate 253 near the drain pipe 240 can be constructed as a triangle, and the end of the second guide plate 254 near the drain pipe 240 can also be constructed as a triangle. This improves the diversion effect of condensate water.

[0101] In an alternative embodiment of the aforementioned portable air conditioner, the lower end face of the drain pipe 240 near the water distribution member 250 is arranged at an angle relative to the lower air duct plate; and / or, the diameter of the drain pipe 240 gradually decreases from top to bottom.

[0102] By arranging the drain pipe 240 at an angle relative to the lower air duct plate 220 near the lower end face of the water distribution component 250, the condensate can flow towards the water distribution component 250 at an inclined angle when it flows out of the drain pipe 240. This arrangement allows the condensate to have a certain horizontal velocity component before contacting the water distribution component 250, enabling the condensate to fall more dispersedly on the water distribution component 250 and avoiding concentrated dripping that would generate greater impact force and noise.

[0103] Furthermore, the inclined lower end face can guide the condensate to flow along the inclined direction, reducing the possibility of condensate accumulating at the end of the drain pipe 240 near the water distribution component 250, further reducing the noise caused by sudden dripping of water. In addition, this inclined arrangement also helps to improve drainage efficiency, allowing condensate to flow along the inclined side end face from the drain pipe 240 to the water distribution component 250, and then into the water collection box 400.

[0104] By designing the drain pipe 240 with its diameter gradually decreasing from top to bottom, the flow velocity of condensate within the drain pipe 240 can be increased, thereby reducing the residence time of condensate within the drain pipe 240 and lowering the probability of noise generated by condensate accumulation. Simultaneously, when the condensate flows out of the drain pipe 240 at a relatively high speed and impacts the water distribution component 250, it can be more effectively dispersed, minimizing the noise generated by concentrated dripping.

[0105] In this design, the diameter of the drain pipe 240 gradually decreases from top to bottom, meaning that the diameter gradually decreases from the end connected to the upper air duct plate 210 to the end near the lower air duct plate 220.

[0106] In addition, this arrangement can also constrain the condensate, making it flow more regularly to the water distribution component 250, improving the stability of the drainage process, and ensuring that noise can be effectively reduced during the operation of the portable air conditioner.

[0107] In an optional embodiment of the aforementioned portable air conditioner, an outdoor heat exchanger 320 is also included. The outdoor heat exchanger 320 is disposed in the outdoor cavity 102, and at least partially corresponds to the water collection box 400. The lower air duct plate 220 is provided with water distribution holes 221, through which condensate in the water collection box 400 drips onto the surface of the outdoor heat exchanger 320.

[0108] Through the water distribution holes 221, condensate in the water collection box 400 drips onto the surface of the outdoor heat exchanger 320. The condensate absorbs heat from the surface of the outdoor heat exchanger 320 and evaporates, thus carrying away a large amount of heat energy. This allows the outdoor heat exchanger 320 to exchange heat more efficiently, improving the cooling effect of the air conditioner. In this way, not only can the temperature of the outdoor heat exchanger 320 be effectively reduced and its heat exchange efficiency improved, but the utilization rate of the condensate cooling capacity can also be increased.

[0109] In addition, by making full use of the condensate in the water collection box 400, the accumulation of condensate in the water collection box 400 can be reduced, thereby reducing the safety hazards that may be caused by water overflow and improving the safety and reliability of the portable air conditioner during operation.

[0110] Optionally, an annular retaining edge 222 is provided circumferentially around the water distribution hole 221.

[0111] The annular baffle 222 allows condensate to accumulate in the collection box 400. When the liquid level exceeds the height of the annular baffle 222, the condensate overflows. This accumulation process allows dust and other impurities to settle. In other words, the annular baffle 222 reduces the impurity content in the condensate, thus preventing corrosion and damage to the outdoor heat exchanger 320 and extending its service life.

[0112] Alternatively, the annular retaining edge 222 may not be provided.
