[0024] 1 to 4, one embodiment of the present invention proposes a ductless mobile air conditioner including a case (not shown), a fan 100, a condensing unit 200, a water storage device, a spray unit, and a shake-off unit. The case has a mounting cavity with an air inlet and an air outlet communicating with the mounting cavity. The fan 100 is mounted in the mounting cavity, with an air inlet end 110 of the fan 100 communicating with the air inlet and an air outlet end 120 of the fan 100 communicating with the air outlet. The condensing unit 200 is mounted in the mounting cavity and located between the fan 100 and the air outlet. A water storage device 300 is mounted in the case and is at least partially located below the condensing unit 200, and can collect water dripping from the surface of the condensing unit 200. The spray unit is attached to the condensation unit 200 and communicates with the water storage device 300, and the spray unit can spray the water in the water storage device 300 onto the condensation unit 200. The shake-off unit is provided in the water storage device 300 and can shake off the water in the water storage device 300 upward onto the condensation unit 200.

[0025] In the ductless mobile air conditioner of the embodiment of the present invention, the air from the outlet end 120 of the fan 100 flows through the condensing unit 200 and is discharged from the exhaust port. By providing a spray unit and a shake-off unit, the spray unit can spray water onto the condensing unit 200 to cool it down, and the shake-off unit can shake water upward onto the condensing unit 200, thereby also cooling it down. As a result, the spray unit and the shake-off unit work together to efficiently cool the condensing unit 200 and effectively cool the air that flows through the condensing unit 200, so that the temperature of the air discharged from the exhaust port reaches a predetermined value. This eliminates the need for an exhaust duct to discharge the air from the exhaust port outdoors, allowing the user to move the mobile air conditioner directly without any additional operations, which is simple to operate and advantageous to improving the user experience.

[0026] The temperature of the air discharged from the exhaust port can reach a preset value, where the preset value is slightly higher than the outdoor temperature value, or the preset value is lower than the outdoor temperature value.

[0027] 1 to 8 , in some embodiments, the condensing unit 200 includes a condenser 210, which includes a condenser tube 220 and a group of fins, which include a plurality of fins (not shown) spaced apart along a first direction, and the condenser tube 220 is drilled through all of the fins along the first direction. The spray unit includes a spray pipe 400 communicating with the water storage device 300, which is attached so as to penetrate at least two fins of the condenser 210 along the first direction. The spray pipe 400 has at least one spray port 410, which is located between two adjacent fins. This allows water in the spray pipe 400 to be sprayed between the two adjacent fins by the spray port 410, thereby effectively lowering the temperature of the fins, i.e., the condenser 210, and further lowering the temperature of the air flowing through the condenser 210 so that the temperature of the air discharged from the exhaust port reaches a predetermined value.

[0028] 1 to 8, in some embodiments, the spray pipe 400 is installed through the upper end of the condenser 210, and the spray pipe 400 has at least two spray ports 410, each of which faces downward and is located between two adjacent fins, and all of the spray ports 410 are spaced apart sequentially along the first direction. This allows water in the spray pipe 400 to spray onto the surfaces of the fins from top to bottom, thereby lowering the temperature of the fins. By providing multiple spray ports 410, the number of fins that can be sprayed by the spray pipe 400 can be further increased, and the cooling effect on the condenser 210 can be further improved.

[0029] 7 and 8, in some embodiments, the spray pipe 400 includes an upper pipe shell 420 and a lower pipe shell 430 that engage with each other, and the upper pipe shell 420 and the lower pipe shell 430 surround each other to form a water passage 440 that communicates with the water storage device 300, and the spray port 410 is opened in the lower pipe shell 430 and communicates with the water passage 440. By providing the spray pipe 400 in the upper pipe shell 420 and the lower pipe shell 430, it is possible to facilitate the production and assembly of the spray pipe 400.

[0030] 1 to 8 , in some embodiments, the outlet end and the exhaust port of the fan 100 are spaced apart along a second direction, which is perpendicular to the first direction. The gaps between two adjacent fins have one end facing the fan 100 and the other end facing the exhaust port. This allows air from the outlet end 120 of the fan 100 to flow through the gaps between each fin in the fin group before being discharged through the exhaust port, thereby improving the smoothness of the exhaust air. Furthermore, the spray unit can spray water into the gaps between two adjacent fins, which not only lowers the temperature of the fins but also lowers the temperature of the air flowing through the gaps, thereby improving the cooling effect on the air flowing through the condenser 210.

[0031] In some embodiments, the second direction may specifically be the length direction of the case, and the first direction may specifically be the width direction of the case.

[0032] In some embodiments, a control module is further provided in the case, the condensing unit 200 is provided with a temperature sensor for detecting the temperature of the fins, a control valve capable of controlling the water supply flow rate of the spray pipe 400 is provided between the spray pipe 400 and the water storage device 300, and the control valve is provided with a flow rate sensor capable of detecting the water supply flow rate of the spray pipe 400, the temperature sensor, the flow rate sensor and the control valve are all electrically connected to the control module, the control module can control the operation of the control valve based on the temperature information fed back by the temperature sensor, and the control module can control the operation of the control valve based on the flow rate information fed back by the flow rate sensor.

[0033] In the above structure, the temperature sensor can detect the temperature of the fins in the condensing unit 200. When the temperature of the fins in the condensing unit 200 reaches a predetermined temperature, it indicates that the temperature of the fins is relatively high and that spray cooling is required via the spray pipe 400. At this time, the temperature sensor can transmit the detected temperature information to the control module, which can control the start of operation of the control valve. The flow sensor can detect the water supply flow rate of the spray pipe 400. The control module can control the opening and closing degree of the control valve based on the flow rate information fed back by the flow sensor. This allows the opening and closing of the control valve to be flexibly adjusted based on the fin temperature. When the fin temperature rises, the control valve increases the water supply flow rate to the spray pipe 400, and when the fin temperature drops, the control valve decreases the water supply flow rate to the spray pipe 400, thereby making it possible to more flexibly cool and cool the condensing unit 200.

[0034] 1 to 10, in some embodiments, the condensation unit 200 includes at least two condensers 210, at least one of which is equipped with a spray unit, and the lower ends of two adjacent condensers 210 in one set are spaced apart to form a shake-off gap 230, and the shake-off unit is located below the shake-off gap 230 or at least partially within the shake-off gap 230, so that the shake-off unit can shake off water in the water storage device 300 upward into the shake-off gap 230, thereby lowering the temperature of the two adjacent condensers 210, further improving the cooling and temperature-reducing effect on the condensation unit 200 and further improving the cooling and temperature-reducing effect on the wind flowing through the condensers 210.

[0035] 1 to 10 , in some embodiments, the shake-off gap 230 between two adjacent condensers 210 gradually decreases from bottom to top, thereby preventing water shaken off from the shake-off units from passing directly through the shake-off gap 230 and being shaken off upward to the outside of the condensing unit 200. Note that in some embodiments, the condensing unit 200 further includes an end plate 240, which is provided at an end of the condenser 210 in the first direction and can block the shake-off gap 230, thereby preventing water shaken off from the shake-off units from passing directly through both ends of the shake-off gap 230 and being shaken off to the outside of the condensing unit 200.

[0036] 1 to 10 , in some embodiments, a condensing unit 200 includes two condensers 210, with a shake-off gap 230 between the two condensers 210, and a spray pipe 400 attached to one of the condensers 210. This structure is merely an exemplary explanation of the present invention, and in addition to attaching a spray pipe 400 to one condenser 210, both condensers 210 can also be attached with a spray pipe 400, without any specific limitations of the present invention. The number of condensers 210 in the condensing unit 200 can be three, four, or more, in addition to two. When the number of condensers 210 is three or more, a shake-off gap 230 can be provided between every two adjacent condensers 210, and a shake-off unit can be provided in each shake-off gap 230, without any specific limitations of the present invention.

[0037] 1 to 10, in some embodiments, the shake-off unit includes a shake-off wheel 500 and a drive device 520, the drive device 520 is mounted in the mounting cavity and is transmission-connected to the shake-off wheel 500, the shake-off wheel 500 extends partially downward into the water storage device 300, the shake-off wheel 500 extends partially upward into the shake-off gap 230, and the drive device 520 drives the shake-off wheel 500 to rotate, causing the water in the water storage device 300 to rise into the shake-off gap 230. The outer periphery of the shake-off wheel 500 is provided with a shake-off portion 510 arranged along the circumferential direction of the shake-off wheel 500, the thickness of the shake-off portion 510 gradually decreasing from the inside to the outside, and at least one surface of the shake-off portion 510 is provided with a plurality of shake-off grooves 511 arranged at intervals along the circumferential direction of the shake-off wheel 500, the shake-off grooves 511 having an arc shape and extending from the inner end of the shake-off portion 510 to the outer end of the shake-off portion 510. This allows the water in the water storage device 300 to be effectively shaken upward into the shake-off gap 230, thereby lowering the temperature and cooling the condenser 210.

[0038] 1 to 4, in some embodiments, the water storage device 300 includes a water storage tank 310 and a water receiving tank 320. The water receiving tank 320 is provided below the condensing unit 200, and the vertical projection of the condensing unit 200 is located within the water receiving tank 320. The shake-off wheel 500 is partially located within the water receiving tank 320, so that water in the water receiving tank 320 can be shaken upward into the condensing unit 200 to lower the temperature of the condensing unit 200, and the water receiving tank 320 can efficiently receive water dripping downward from the surface of the condensing unit 200. The water storage tank 310 is provided in the case and communicates with the water receiving tank 320. A water pump 330 is provided between the spray pipe 400 and the water storage tank 310. One end of the water pump 330 communicates with the water storage tank 310 and the other end communicates with the spray pipe 400. This allows the water in the water storage tank 310 to be pumped up the spray pipe 400 by the water pump 330 and sprayed downward onto the condensation unit 200, and the water above the condensation unit 200 flows downward and drips into the water receiving tank 320, before passing through the water receiving tank 320 and flowing back into the water storage tank 310.

[0039] 1 to 4, in some embodiments, the water storage tank 310 is located below the water receiving tank 320, the water receiving tank 320 is provided with a water outlet pipe 321 that communicates with the water storage tank 310, the bottom wall of the water receiving tank 320 is further provided with a downwardly concave flow guide groove 322, the water outlet pipe 321 is provided on the side wall of the water receiving tank 320, and the flow guide groove 322 extends until it communicates with the water outlet pipe 321, thereby enabling the water in the water receiving tank 320 to be efficiently guided into the water storage tank 310.
