[0044] In combination Figures 1 to 9As shown, the utility model provides a kind of mobile air conditioner, including shell 100, outdoor air duct component 200, indoor heat exchanger 310, outdoor heat exchanger 320, water pan 211 and water collecting box 221.The inside of shell 100 is formed with cavity.Outdoor air duct component 200 is set in cavity, including the upper air duct plate 210, lower air duct plate 220 and volute 230 that limit out wind wheel space, the upper air duct plate 210 separates cavity into indoor cavity 101 and outdoor cavity 102, wherein, indoor cavity 101 is equipped with indoor heat exchanger 310, and outdoor cavity 102 is equipped with outdoor heat exchanger 320.Water pan 211 is structured in the upper air duct plate 210, for the condensed water generated by indoor heat exchanger 310, wherein, the upper air duct plate 210 is opened with the drain hole corresponding to water pan 211.Water collecting box 221 is formed in lower air duct plate 220 corresponding to drain hole, and water collecting box 221 is arranged corresponding to outdoor heat exchanger 320, and extends towards the direction of upper air duct plate 210, wherein, lower air duct plate 220 is opened with multiple water distribution holes 222 corresponding to water collecting box 221.Water hole 223 is opened in lower air duct plate 220, corresponding to outdoor heat exchanger 320 and being arranged close to the side box wall of water collecting box 221.

[0045] Optionally, the inside of shell 100 is provided with a cavity, which is separated into indoor cavity 101 and outdoor cavity 102 by outdoor air duct component 200 arranged inside. Specifically, outdoor air duct component 200 includes oppositely arranged upper air duct plate 210 and lower air duct plate 220, and volute 230. Upper air duct plate 210, lower air duct plate 220 and volute 230 jointly limit out wind wheel space, and outdoor fan 410 is arranged in the wind wheel space. Upper air duct plate 210 serves as a partition plate to separate the cavity into indoor cavity 101 and outdoor cavity 102.

[0046] Correspondingly, shell 100 is respectively provided with indoor air inlet and indoor air outlet corresponding to indoor cavity 101, and outdoor air inlet and outdoor air outlet corresponding to outdoor cavity 102. Indoor fan is further arranged in indoor cavity 101. Under the drive of outdoor fan 410, air enters outdoor cavity 102 through outdoor air inlet, exchanges heat with outdoor heat exchanger 320, flows to outdoor air duct component 200, and then flows out of shell 100 through outdoor air outlet. Under the drive of indoor fan, indoor air enters indoor cavity 101 through indoor air inlet, exchanges heat with indoor heat exchanger 310, and then flows to indoor air outlet. Lower air duct plate 220 is provided with air scoop inlet, and volute 230 is provided with air duct outlet corresponding to outdoor air outlet.

[0047] Optionally, indoor fan and outdoor fan 410 are connected by double-shaft motor, and the double-shaft motor is arranged in the wind wheel space.

[0048] Alternatively, indoor fan and outdoor fan 410 are respectively connected with driving motor.

[0049] In the cooling mode, the indoor heat exchanger 310 is used as an evaporator and the outdoor heat exchanger 320 is used as a condenser.

[0050] Optionally, the upper air duct plate 210 not only has the function of a partition plate, but also forms a water pan 211 corresponding to the indoor heat exchanger 310. The indoor heat exchanger 310 is installed in the water pan 211, and the water pan 211 receives the condensed water generated by the indoor heat exchanger 310. Correspondingly, the upper air duct plate 210 as the bottom wall of the water pan 211 is provided with a drain hole. A water collecting box 221 is arranged below the drain hole, and the water collecting box 221 receives the condensed water flowing out through the drain hole. Specifically, the side wall of the water collecting box 221 extends towards the upper air duct plate 210, the lower air duct plate 220 constitutes the bottom wall of the water collecting box 221, and the upper part of the water collecting box 221 is open to avoid the splashing of condensed water. Since the water collecting box 221 is arranged on the lower air duct plate 220, it has a certain distance from other components in the outer shell 100, so as to avoid the condensed water from splashing on other components and causing problems such as rusting and short circuit of other components. Further, the water collecting box 221 is located between the upper air duct plate 210 and the lower air duct plate 220, which is equivalent to being independent of the indoor cavity 101 and the outdoor cavity 102, and can further improve the safety of the mobile air conditioner. Specifically, the side wall of the water collecting box 221 is formed on the upper surface of the lower air duct plate 220 and extends towards the upper air duct plate 210, and part of the plate body of the lower air duct plate 220 serves as the bottom wall of the water collecting box 221.

[0051] Optionally, the side wall of the water collecting box 221 is integrally formed with the lower air duct plate 220.

[0052] Alternatively, the side wall of the water collecting box 221 is fixedly connected with the lower air duct plate 220.

[0053] Optionally, the lower air duct plate 220 as the bottom wall of the water collecting box 221 is provided with a water distribution hole 222 in the space surrounded by the corresponding side wall, and the water distribution hole 222 is located above the outdoor heat exchanger 320 and corresponds to the outdoor heat exchanger 320. Through the arrangement of the water distribution hole 222, the low-temperature condensed water can drop onto the outdoor heat exchanger 320 to cool the outdoor heat exchanger 320 and fully utilize the cold energy of the condensed water.

[0054] Optionally, a water passing hole 223 is arranged on the lower air duct plate 220 close to the water collecting box 221. Since the temperature of the condensed water in the water collecting box 221 is low, condensation water will be generated on the outer side wall of the water collecting box 221. These condensation waters flow along the side wall of the water collecting box 221 to the lower air duct plate 220, and then flow to other parts or components, causing problems such as rusting of components, short circuit of electrical elements, or breeding of bacteria. Therefore, through the arrangement of the water passing hole 223, the condensation water generated on the water collecting box 221 can be introduced into the outdoor cavity 102, thereby improving the safety.

[0055] Optionally, the shell 100 further comprises a bottom plate 110, and the outdoor heat exchanger 320 is arranged between the lower air duct plate 220 and the bottom plate 110.

[0056] In the above technical solution, the water collecting box 221 extending towards the upper air duct plate 210 is arranged on the lower air duct plate 220, so that the condensed water discharged by the water pan 211 can be first collected to avoid splashing of the condensed water everywhere, thereby improving safety; and then the collected condensed water can be uniformly and stably dripped on the outdoor heat exchanger 320 through the water distribution holes 222 arranged correspondingly on the lower air duct plate 220, thereby ensuring the cooling effect of the outdoor heat exchanger 320. The water passing hole 223 arranged on the side box wall of the lower air duct plate 220 close to the water collecting box 221 can guide the condensed water generated on the side box wall of the water collecting box 221 to the outdoor cavity 102 and then to the outdoor heat exchanger 320, thereby avoiding the condensed water from flowing to other components of the outdoor air duct assembly 200, and improving safety.

[0057] In the above optional embodiment of the mobile air conditioner, the water passing hole 223 is arranged on the side box wall of the water collecting box 221.

[0058] By arranging the water passing hole 223 on the corresponding side box wall of the water collecting box 221, the condensed water generated on the side box wall can directly flow towards the water passing hole 223 and then drip on the outdoor heat exchanger 320, thereby reducing the flow of the condensed water on the lower air duct plate 220 and reducing bacterial breeding.

[0059] In the above optional embodiment of the mobile air conditioner, the water passing hole 223 comprises a first hole wall arranged opposite to the side box wall of the water collecting box 221; and a portion of the side box wall of the water collecting box 221 corresponding to the first hole wall gradually increases in distance from the first hole wall from top to bottom.

[0060] In this way, the condensed water can directly drip on the outdoor heat exchanger 320, thereby improving flowability and avoiding the condensed water from generating a water film on the lower surface of the lower air duct plate 220 due to its own adhesive force, thereby causing retention of the condensed water.

[0061] Herein, the lower surface of the lower air duct plate 220 refers to a surface facing the outdoor heat exchanger 320, and the upper surface is opposite to the lower surface of the lower air duct plate 220. From top to bottom refers to a direction from the upper surface to the lower surface of the lower air duct plate 220.

[0062] Alternatively, a portion of the side box wall of the water collecting box 221 corresponding to the first hole wall is constant in distance from the first hole wall from top to bottom.

[0063] In the above optional embodiment of the mobile air conditioner, a recessed portion is arranged on the lower air duct plate 200 around the outer periphery of the water collecting box 221, and the water passing hole 223 is arranged at the lowest position of the recessed portion.

[0064] Through the setting of the recess, the condensed water flowing downward along the sidewall of the water collecting box 221 can flow into the recess. Since the water passing hole 223 is arranged at the lowest part of the recess, the flowability of the condensed water can be improved, and the flow into the outdoor cavity 102 can be improved.

[0065] Alternatively, the recess is not arranged.

[0066] In the optional embodiment of the mobile air conditioner described above, the water collecting box 221 includes two short sidewalls arranged oppositely in the length direction of the outdoor heat exchanger 320, and the water passing hole 223 is arranged corresponding to the short sidewall.

[0067] Since the water collecting box 221 is arranged above the outdoor heat exchanger 320, by arranging the water passing hole 223 corresponding to the short sidewall, the condensed water can be directly dripped onto the outdoor heat exchanger 320 through the water passing hole 223, thereby cooling the outdoor heat exchanger 320. Not only the cold energy of the condensed water is fully utilized, but also the lower air duct plate 220 is prevented from being in a humid environment, and bacteria breeding is avoided.

[0068] Alternatively, a plurality of water passing holes 223 are arranged around the circumference of the water collecting box 221.

[0069] In the optional embodiment of the mobile air conditioner described above, the upper surface of the lower air duct plate 220 is provided with a first stop rib 224 matching the shape of the volute 230. The inner side surface of the first stop rib 224 abuts against the outer surface of the volute 230, and one side of the outer side surface of the first stop rib 224 is provided with the water collecting box 221 and the water passing hole 223.

[0070] Through the arrangement of the first stop rib 224, on the one hand, the installation position of the volute 230 can be limited, and on the other hand, the condensed water generated on the outer wall surface of the water collecting box 221 can be blocked, so as to prevent the condensed water from flowing into the volute 230, thereby avoiding the safety problem of electrical elements or other components.

[0071] Optionally, the upper surface of the lower air duct plate 220 is further provided with a second stop rib 225 arranged on the inner side surface of the first stop rib 224 and spaced apart from the first stop rib 224. The second stop rib 225 matches the shape of the volute 230. In this way, the volute 230 can be clamped between the first stop rib 224 and the second stop rib 225. On the one hand, the fixation and installation of the volute 230 are ensured, and on the other hand, the condensed water can be blocked twice, thereby improving the safety.

[0072] Since the water collecting box 221 is arranged on the outer side of the first stop rib, i.e., outside the volute 230. In this way, on the one hand, the space between the upper air duct plate 210 and the lower air duct plate 220 outside the volute 230 can be fully utilized, the space utilization is improved, and the side box wall of the water collecting box 221 can be used to keep a certain distance from other components to avoid condensation of the surrounding components; on the other hand, the high-temperature air in the volute can be prevented from contacting the low-temperature condensed water, so that the condensed water is prevented from being generated in the volute 230, and the safety of the mobile air conditioner and the outdoor fan 410 is improved.

[0073] Optionally, the water distribution holes 222 are arranged in multiple rows along the length direction of the outdoor heat exchanger 320.

[0074] By arranging multiple rows of water distribution holes 222, and multiple water distribution holes 222 in each row, the condensed water can be dripped on the outdoor heat exchanger 320 as much as possible, and the cooling effect is improved.

[0075] Optionally, the distances between adjacent water distribution holes 222 are equal. By making the distances between adjacent water distribution holes 222 equal, the condensed water can be uniformly dripped on the outdoor heat exchanger 320, thereby improving the cooling effect. Optionally, multiple water distribution holes 222 are arranged in each row.

[0076] Alternatively, the distances between adjacent water distribution holes 222 are not equal.

[0077] Optionally, the diameter of the water distribution hole 222 is 2-3 times the distance between adjacent fins of the outdoor heat exchanger 320.

[0078] By setting the diameter of the water distribution hole 222 to be 2-3 times the distance between adjacent fins of the outdoor heat exchanger 320, the water distribution hole 222 can be prevented from being blocked due to the influence of the surface tension and viscosity of the condensed water when the diameter of the water distribution hole 222 is too small.

[0079] Preferably, the diameter of the water distribution hole 222 is 6 mm.

[0080] Optionally, the diameter of the water distribution hole 222 is constant from the upper surface to the lower surface of the upper and lower air duct plates 220, forming a cylindrical through hole.

[0081] Alternatively, the diameter of the water distribution hole 222 gradually decreases from the upper surface to the lower surface of the upper and lower air duct plates 220. In this way, after the condensed water passes through the water distribution hole 222, it is in the form of a thin line and drips on the outdoor heat exchanger 320, so that the condensed water on the outdoor heat exchanger 320 is thin, and the heat exchange effect is improved.

[0082] In the optional embodiment of the mobile air conditioner described above, the lower air duct plate 220 is provided with a sunken part recessed towards the outdoor heat exchanger 320, and the water distribution hole 222 is arranged in the sunken part.

[0083] By setting the sinking part, the condensed water entering the water collecting box 221 can automatically flow towards the lower place, which is beneficial to the collection of the condensed water, thereby ensuring the flow of the water in the water distribution hole 222.

[0084] Alternatively, the sinking part is not arranged.

[0085] In the optional embodiment of the mobile air conditioner described above, in combination with Figure 7 、 Figure 8 As shown in the drawings, the upper surface of the lower air duct plate 220 is provided with a first surrounding barrier rib 2221 surrounding the circumference of the water distribution hole 222.

[0086] By arranging the first surrounding barrier rib 2221, the liquid level in the water collecting box 221 can be higher than the first surrounding barrier rib 2221, and then flow to the outdoor heat exchanger 320 through the water distribution hole 222, which can make the flow of the condensed water more gentle and uniform.

[0087] Optionally, the outer surface of the first surrounding barrier rib 2221 is parallel to the upper surface of the lower air duct plate 220.

[0088] Alternatively, the outer surface of the first surrounding barrier rib 2221 is arranged to be inclined downwardly towards the direction of the center of the circle, so as to form a concave in the inner ring of the first surrounding barrier rib 2221. The outer surface of the first surrounding barrier rib 2221 is the side surface away from the upper surface of the lower air duct plate 220.

[0089] Alternatively, the first surrounding barrier rib 2221 is not arranged.

[0090] In the optional embodiment of the mobile air conditioner described above, in combination with Figure 8 、 Figure 9 As shown in the drawings, the lower surface of the lower air duct plate 220 is provided with a second surrounding barrier rib 2222 surrounding the circumference of the water distribution hole 222.

[0091] By arranging the second surrounding barrier rib 2222, a water column can be formed during the flow of the condensed water towards the outdoor heat exchanger 320, so as to avoid the formation of a liquid film on the lower surface of the lower air duct plate 220 under the water distribution hole 222 due to the action of the self-tension and viscosity of the condensed water, thereby blocking the water distribution hole 222.

[0092] Optionally, the outer surface of the second surrounding barrier rib 2222 is parallel to the lower surface of the lower air duct plate 220.

[0093] Alternatively, the outer surface of the second surrounding barrier rib 2222 is arranged to be inclined upwardly along the direction away from the center of the circle. The outer surface of the second surrounding barrier rib 2222 is the side surface away from the lower surface of the lower air duct plate 220.

[0094] Alternatively, the second surrounding barrier rib 2222 is not arranged.

[0095] In the optional embodiment of the mobile air conditioner described above, in combination withFigure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown in FIGS. 21, 22, 23 and 24, the lower surface of the lower air duct plate 220 is provided with support ribs 226, which are arranged around the periphery of the outdoor heat exchanger 320 and abut against the top end edge of the outdoor heat exchanger 320.

[0096] With the provision of the support ribs 226, a spacing is formed between the water distribution holes 222 and the top end edge of the outdoor heat exchanger 320, which is conducive to the formation of a liquid column, so as to facilitate the uniform distribution of the condensed water, while the support ribs 226 can also play a role in guiding the condensed water on the lower surface of the lower air duct plate 220. In addition, the support ribs 226 can also play a role in sealing the top end of the outdoor heat exchanger 320.

[0097] Optionally, the area enclosed by the annular ribs formed by the support ribs 226 is smaller than the area of the top end edge of the outdoor heat exchanger 320, so as to ensure the stability of the abutment between the support ribs 226 and the outdoor heat exchanger 320.

[0098] Optionally, the support ribs 226 are provided with flat plate portions facing the end face of the outdoor heat exchanger 320, so that the cross-sectional area of the flat plate portions is greater than that of the support ribs, so as to increase the contact area of the outdoor heat exchanger 320 and improve the sealing performance.

[0099] Alternatively, the support ribs 226 are not provided with flat plate portions facing the end face of the outdoor heat exchanger 320.

[0100] Alternatively, the support ribs 226 are not provided.

[0101] In the optional embodiments of the mobile air conditioner described above, in combination with Figure 5 As shown in FIGS. 21, 22, 23 and 24, the support ribs 226 are provided with corner reinforcing ribs 227 at the connecting corners of the support ribs 226 and the lower air duct plate 220.

[0102] With the provision of the corner reinforcing ribs 227, stress concentration at the connecting portions of the support ribs 226 and the lower air duct plate 220 can be prevented, so as to improve the structural strength and stability of the support ribs 226.

[0103] Alternatively, the corner reinforcing ribs 227 are not provided.

[0104] In the optional embodiments of the mobile air conditioner described above, the outer wall surface of the side box wall of the water collecting box 221 is coated with a hydrophobic coating.

[0105] With the provision of the hydrophobic coating, the flowability of water on the outer wall surface of the side box wall of the water collecting box 221 can be improved, so as to prevent the condensed water from stagnating on the upper surface of the lower air duct plate 220.

[0106] Optionally, the hydrophobic coating comprises a graphene coating. The graphene coating has strong hydrophobicity, which can promote the rapid flow of the condensed water on the outer wall surface of the side box wall of the water collecting box 221.

[0107] Optionally, the hydrophobic coating layer comprises a nano-super-hydrophobic coating layer. The nano-super-hydrophobic coating layer has very low surface tension, and liquid is difficult to stay on the surface of the nano-super-hydrophobic coating layer, thereby facilitating the flowability of the condensed water on the outer wall surface of the side wall of the water collecting box 221, and avoiding the condensed water from staying on the upper surface of the lower air duct plate 220, thereby reducing the adhesion and accumulation of dust and other dirt on the lower air duct plate 220.

[0108] Alternatively, the outer wall surface of the side wall of the water collecting box 221 is not provided with a hydrophobic coating layer.

[0109] Optionally, the upper surface of the lower air duct plate 220 is coated with a hydrophobic coating layer. The flowability of the condensed water is improved, and the condensed water is prevented from staying in the water collecting box 221.
