[0046] Optionally, the cavity of the shell 100 is divided into the indoor cavity 102 and the outdoor cavity 101 by the outdoor air duct assembly 200. The indoor air heat exchange assembly is arranged in the indoor cavity 102, and at least includes the indoor fan 320 and the indoor heat exchanger 420 to exchange heat with the air in the indoor environment. The indoor heat exchanger 420 can divide the indoor cavity 102 into the air inlet space and the air outlet space. The indoor air inlet 103 is arranged on the different side of the shell 100 corresponding to the first heat exchange part 421 and the second heat exchange part 422, and is connected with the air inlet space. The indoor fan 320 is arranged in the air outlet space and is drivingly connected with the second output shaft 620 of the motor assembly 600. Under the driving of the motor assembly 600, the indoor fan 320 rotates, and drives the indoor air to enter the air inlet space through the indoor air inlet 103, and then flows through the indoor heat exchanger 420 to exchange heat with the indoor heat exchanger 420, and then flows to the air outlet space. By constructing the indoor heat exchanger 420 as the first heat exchange part 421 and the second heat exchange part 422, and corresponding arranging the indoor air inlet 103 on the different side of the shell 100, the heat exchange capacity of the indoor heat exchanger 420 can be increased, so that the heat exchange capacity of the mobile air conditioner is ensured while the volume of the mobile air conditioner is reduced.

[0047] Optionally, the outdoor fan 310 and the motor assembly 600 are arranged in the outdoor air duct assembly 200. The outdoor air duct assembly 200 is connected with the outdoor cavity 101. The motor assembly 600 drives the outdoor fan 310 to rotate to flow the air and cool the outdoor heat exchanger 410 and the electrical box 500 in the outdoor cavity 101. The outdoor heat exchanger 410 and the electrical box 500 are arranged in the outdoor cavity 101, which can improve the space utilization and drive the air around the electrical box 500 to flow to ensure the heat dissipation of the electrical box 500.

In this way, the number of structural components in the mobile air conditioner can be reduced to reduce the space occupation, thereby improving the space utilization and reducing the volume of the mobile air conditioner. In addition, the motor assembly 600 can drive the indoor fan 320 and the outdoor fan 310 to rotate at the same time, thereby ensuring the synchronization of the operation of the mobile air conditioner, avoiding the idle rotation of the indoor fan 320 or the outdoor fan 310, and improving the energy utilization.

[0049] Optionally, the first output shaft 610 and the second output shaft 620 are coaxially arranged.

[0050] Optionally, the compressor is arranged in the outdoor cavity 101, and the compressor is connected with the indoor heat exchanger 420 and the outdoor heat exchanger 410 through the refrigerant pipeline.

[0051] In the case of adopting the above technical solutions, by arranging the motor assembly in the outdoor air duct assembly, and by arranging one motor assembly to be drivingly connected with the indoor fan and the outdoor fan, the components of the mobile air conditioner can be reduced, the space occupied can be small, and thus the volume of the mobile air conditioner can be reduced; meanwhile, by arranging the indoor heat exchanger as the first heat exchange part and the second heat exchange part which are connected in a bending manner, and by arranging the indoor air inlet on the corresponding side of the shell, the heat exchange capacity of the indoor heat exchanger can be increased, and thus the heat exchange capacity of the mobile air conditioner can be ensured. In this way, the volume of the mobile air conditioner can be reduced while ensuring the refrigeration capacity of the mobile air conditioner, and the safety can be improved.

[0052] In the optional embodiment of the mobile air conditioner, a first included angle is formed between the outdoor heat exchanger 410 and the electrical appliance box 500, and the first included angle is greater than or equal to 30° and less than or equal to 90°.

[0053] By forming the first included angle between the outdoor heat exchanger 410 and the electrical appliance box 500, the distance between the end of the electrical appliance box 500 away from the outdoor heat exchanger 410 and the outdoor heat exchanger 410 can be reduced, so as to facilitate the flow of air around the electrical appliance box 500, and thus the cooling of the electrical appliance box can be facilitated.

[0054] Optionally, the included angle between the outdoor heat exchanger 410 and the electrical appliance box 500 can be 30°, 45°, 60°, 70°, 90°, etc.

[0055] In the optional embodiment of the mobile air conditioner, the outdoor heat exchanger 410 is correspondingly arranged below the first heat exchange part 421 / second heat exchange part 422, and the extending direction of the first heat exchange part 421 / second heat exchange part 422 is the same.

[0056] Specifically, the outdoor heat exchanger 410 is correspondingly arranged below the first heat exchange part 421, or the outdoor heat exchanger 410 is correspondingly arranged below the second heat exchange part 422. Here, the extending direction of the first heat exchange part 421 or the second heat exchange part 422 refers to the length direction of the first heat exchange part 421 or the second heat exchange part 422, i.e. the direction from the left side to the right side of the first heat exchange part 421 / second heat exchange part 422 when the mobile air conditioner is vertically placed (i.e. in the position in the use state).

[0057] In this way, the structure of the mobile air conditioner can be more compact, the overall volume can be reduced to improve the space utilization, and meanwhile, the length of the pipes and the connecting pieces of the mobile air conditioner can be reduced, the flow resistance and energy loss of the refrigerant can be reduced, and thus the energy efficiency ratio of the mobile air conditioner can be improved.

[0058] Alternatively, the outdoor heat exchanger 410 is configured with a first outdoor heat exchange section and a second outdoor heat exchange section connected by a bend, and arranged below the first heat exchange section 421 and the second heat exchange section 422, respectively.

[0061] Specifically, the first side 110 and the second side 120 are respectively provided with the first opening 111 and the second opening 121 corresponding to the first heat exchange section 421 and the second heat exchange section 422, and the first opening 111 and the second opening 121 jointly constitute the indoor air inlet 103. The indoor air enters the air inlet space of the indoor cavity 102 through the indoor air inlet 103. After heat exchange with the indoor heat exchanger 420, the indoor air flows to the indoor air outlet 131 on the third side 130, thereby realizing the circulation of the indoor air and ensuring the adjustment of the indoor air.

[0062] The first side 110 is further provided with an outdoor air inlet 112.

The outdoor air duct inlet 201 of the outdoor air duct assembly 200 is in communication with the outdoor cavity 101, and the outdoor air duct outlet 202 is arranged correspondingly to the outdoor air outlet 113 on the first side 110. In this way, the flow of air in the outdoor cavity 101 can be ensured. In this way, under the drive of the motor assembly 600, the outdoor fan 310 operates, so that the air flows through the outdoor air inlet 112 and the outdoor heat exchanger 410 in turn, enters the outdoor air duct assembly 200, passes through the outdoor fan 310, and then flows out of the outdoor cavity 101 through the outdoor air duct outlet 202 and the outdoor air outlet 113, thereby ensuring the flow of air in the outdoor cavity 101 and ensuring heat exchange with the outdoor heat exchanger 410.

[0063] Optionally, the first opening 111 is in communication with the second opening 121.

[0066] In the optional embodiment of the mobile air conditioner described above, 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 is arranged to carry the indoor heat exchanger 420 and is configured with a water pan 211 corresponding to the indoor heat exchanger 420. The lower air duct plate 220 is arranged opposite to the upper air duct plate 210. The volute 230, together with the upper air duct plate 210 and the lower air duct plate 220, defines an outdoor air duct for accommodating the outdoor fan 310 and the motor assembly 600; wherein the motor assembly 600 is installed on the upper air duct plate 210, the air duct inlet 201 of the outdoor air duct is formed on the lower air duct plate 220, and the air duct outlet 202 is formed on the volute 230 corresponding to the outdoor air outlet 113.

[0067] The upper air duct plate 210 not only serves as a partition between the outdoor cavity 101 and the indoor cavity 102, but also can be used to fix the motor assembly 600; by arranging the air duct inlet 201 and the air duct outlet 202 on the lower air duct plate 220 and the volute 230 respectively, the outdoor air duct is in communication with the outdoor cavity 101, and the flow efficiency of the air under the drive of the outdoor fan 310 can be ensured.

[0068] Optionally, the upper air duct plate 210 and the shell 100 bound the indoor cavity 102, and the indoor heat exchanger 420 is arranged on the upper air duct plate 210, and the upper air duct plate 210 is provided with a water pan 211 of the indoor heat exchanger 420, so as to receive condensed water generated by the indoor heat exchanger 420 when the mobile air conditioner operates in a cooling mode. The shape of the water pan 211 is matched with the indoor heat exchanger 420, so as to optimize the utilization of the space.

[0069] Further, the upper air duct plate 210 is provided with a mounting hole of the motor assembly 600, the shell of the motor assembly 600 is matched with the shape of the mounting hole, and a mounting side is arranged around the circumference of the shell of the motor assembly 600, the mounting side is clamped on the upper surface of the upper air duct plate 210, and is screwed with the upper air duct plate 210. The motor assembly 600 is arranged in the outdoor air duct, and in the case that the shell is fixed in the mounting hole, the upper half of the motor assembly 600 protrudes out of the outdoor air duct assembly 200 and extends into the indoor cavity 102, so as to realize the connection with the indoor fan 320.

[0070] Optionally, the volute 230 is arranged around the circumferences of the upper air duct plate 210 and the lower air duct plate 220, so as to jointly form the outdoor air duct.

[0071] In the optional embodiment of the mobile air conditioner, the outdoor air duct assembly 200 further comprises a water receiving box 240. The water receiving box 240 is arranged on the lower air duct plate 220 corresponding to the water pan, extends towards the upper air duct plate 210, and is arranged to receive the condensed water of the water pan 211, wherein the water receiving box 240 is located outside the volute 230.

[0072] The arrangement of the water receiving box 240 can receive the condensed water in the water pan 211, so as to ensure the discharge of the condensed water. By arranging the water receiving box 240 outside the volute 230 and on the lower air duct plate 220, on the one hand, the utilization rate between the upper air duct plate 210 and the lower air duct plate 220 can be improved, and on the other hand, the problem that the condensed water enters the outdoor air duct and causes rust of the outdoor fan 310 and the like can be avoided.

[0073] Specifically, the upper air duct plate 210 is provided with a drainage member at a position corresponding to the water receiving box 240, and the condensed water in the water pan 211 enters the water receiving box 240 through the drainage member, so as to avoid the water in the water pan overflowing to other positions of the upper air duct plate 210. The drainage member can be a drainage hole, a drainage pipe or the like arranged corresponding to the water receiving box 240.

[0074] Further, the water receiving box 240 is arranged on the outer periphery of the volute 230, that is, in the space between the volute 230 and the shell 100, so as to improve the utilization rate of the space.

[0075] Optionally, the volute 230 is configured with an arc-shaped volute tongue at the air duct outlet 202, and an air outlet plate segment towards the outdoor air outlet 113. The arc-shaped volute tongue can block the circulation of air flow and guide the air to the air outlet plate segment, so that the air flows to the outdoor air outlet 113.

[0076] Optionally, the water collecting box 240 and the air duct outlet 202 are arranged on the same side, and the water collecting box 240 is adjacent to the air duct outlet 202. Since the volute 230 of the outdoor fan 310 is usually configured in an arc shape, there is a certain space between the volute 230 and the outer shell 100. By such arrangement, the remaining space of the volute 230 can be fully utilized, so that the space utilization is high.

[0089] The indoor air duct assembly 700 and the outdoor heat exchanger 410 jointly enclose the air flow space, and the indoor fan 320 is arranged in the space enclosed by the two. Correspondingly, the second air duct wall 720 is provided with the outlet of the outdoor air duct assembly 200, which is arranged corresponding to the indoor air outlet 131 on the third side. In this way, under the drive of the motor assembly 600, the indoor fan 320 operates, so that the air flows into the space enclosed by the indoor air duct assembly 700 and the indoor heat exchanger 420 in sequence after flowing through the indoor air inlet 103 and the indoor heat exchanger 420. Further, after passing through the indoor fan 320, the air flows through the indoor air outlet and the indoor air outlet 131, and then flows into the indoor cavity 102, thereby ensuring the flow of indoor air in the indoor cavity 102 and realizing the adjustment of indoor air. The third side 130 is arranged corresponding to the second air duct wall 720.

[0090] In the optional embodiment of the mobile air conditioner, the indoor air duct assembly 700 further comprises an air duct cover plate 730. The air duct cover plate 730 covers the top end of the indoor heat exchanger 420 and is clamped with the first air duct wall 710 and the second air duct wall 720.

[0091] Through the arrangement of the air duct cover plate 730, the sealing performance of the space surrounded by the indoor heat exchanger 420 and the indoor air duct assembly 700 can be improved, so that the air can flow to the outlet of the fan after passing through the indoor heat exchanger 420, and the leakage of the air after heat exchange can be avoided.

[0092] Alternatively, the air duct cover plate 730 is not arranged.
