[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figures 1 to 4 This utility model discloses a tubeless portable air conditioner, including a housing (not shown in the figure), a fan 100, a condenser assembly 200, a water storage device 300, a spray assembly, and a water-spraying assembly. The housing has an installation cavity, and the housing has an air inlet and an air outlet communicating with the installation cavity. The fan 100 is located in the installation cavity, with its air inlet end 110 communicating with the air inlet and its air outlet end 120 communicating with the air outlet. The condenser assembly 200 is located in the installation cavity and between the fan 100 and the air outlet. The water storage device 300 is located in the housing and at least partially below the condenser assembly 200, and the water storage device 300 can collect water dripping from the surface of the condenser assembly 200. The spray assembly is installed on the condenser assembly 200 and communicates with the water storage device 300, and the spray assembly can spray water from the water storage device 300 onto the condenser assembly 200. The water-spinning component is located in the water storage device 300 and is capable of throwing the water in the water storage device 300 upwards to the condensation component 200.

[0040] In the ductless portable air conditioner of this utility model embodiment, the air from the air outlet 120 of the fan 100 can flow through the condenser assembly 200 and be discharged from the exhaust port. By setting up a spray assembly and a water-spinning assembly, the spray assembly can spray water onto the condenser assembly 200 to cool it down. At the same time, the water-spinning assembly can swing water upwards onto the condenser assembly 200, which can also cool it down. Thus, the spray assembly and the water-spinning assembly can work together to achieve a highly efficient cooling effect on the condenser assembly 200, thereby effectively cooling the air flowing through the condenser assembly 200. This ensures that the temperature of the air discharged from the exhaust port reaches a preset value. Therefore, there is no need to set up an exhaust duct to discharge the air from the exhaust port to the outside, allowing users to move the portable air conditioner directly without additional operation. The operation is simple and improves the user experience.

[0041] Understandably, this is to ensure that the temperature of the air discharged from the exhaust vent reaches a preset value, which is either slightly higher than the outdoor temperature or lower than the outdoor temperature.

[0042] Reference Figures 1 to 8 In some embodiments, the condensing assembly 200 includes a condenser 210, which includes a condensing tube 220 and a fin assembly. The fin assembly includes multiple fins (not shown) spaced apart along a first direction. The condensing tube 220 passes through all the fins along the first direction. The spraying assembly includes a spraying tube 400 connected to the water storage device 300. The spraying tube 400 passes through at least two fins of the condenser 210 along the first direction. The spraying tube 400 has at least one spray nozzle 410 located between two adjacent fins. Thus, water from the spraying tube 400 can be sprayed through the spray nozzle 410 to the space between two adjacent fins, thereby effectively cooling the fins, i.e., cooling the condenser 210, and further cooling the air flowing through the condenser 210, so that the temperature of the air discharged from the exhaust port can reach a preset value.

[0043] Reference Figures 1 to 8 In some embodiments, a spray pipe 400 is installed at the upper end of the condenser 210. The spray pipe 400 has at least two spray nozzles 410, each facing downwards and located between two adjacent fins. All spray nozzles 410 are arranged sequentially at intervals along a first direction. This allows water in the spray pipe 400 to be sprayed from top to bottom onto the fin surface to cool the fins. The multiple spray nozzles 410 further increase the number of fins that the spray pipe 400 can reach, thereby further improving the cooling effect on the condenser 210.

[0044] Reference Figure 7 and Figure 8In some embodiments, the spray pipe 400 includes an upper pipe shell 420 and a lower pipe shell 430 that are interlocked. The upper pipe shell 420 and the lower pipe shell 430 enclose each other to form a water passage 440, which is connected to the water storage device 300. The spray nozzle 410 is opened in the lower pipe shell 430 and is connected to the water passage 440. By dividing the spray pipe 400 into an upper pipe shell 420 and a lower pipe shell 430, the production and processing of the spray pipe 400 can be facilitated, as well as the assembly of the spray pipe 400.

[0045] Reference Figures 1 to 8 In some embodiments, the air outlet and exhaust port of the fan 100 are spaced apart along a second direction, which is perpendicular to the first direction. One end of the gap between two adjacent fins faces the fan 100, and the other end faces the exhaust port. Thus, the air from the air outlet 120 of the fan 100 can flow through the gaps between the fins in the fin assembly and then be discharged from the exhaust port, thereby improving the smoothness of exhaust. Furthermore, since the spray assembly can spray water into the gaps between two adjacent fins, it can not only cool the fins but also cool the air flowing through the gaps, further improving the cooling effect on the air flowing through the condenser 210.

[0046] It is understood that in some embodiments, the second direction may specifically be the length direction of the housing, and the first direction may specifically be the width direction of the housing.

[0047] In some embodiments, a control module is also provided inside the housing. The condensation assembly 200 is provided with a temperature sensor for detecting the temperature of the fins. A control valve capable of controlling the water flow rate of the spray pipe 400 is provided between the spray pipe 400 and the water storage device 300. The control valve is provided with a flow sensor capable of detecting the water flow rate of the spray pipe 400. The temperature sensor, the flow 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 information fed back by the flow sensor.

[0048] In the above structure, the temperature sensor can detect the temperature of the fins in the condenser assembly 200. When the temperature of the fins in the condenser assembly 200 reaches the preset temperature, it indicates that the fin temperature is too high and needs to be cooled by spraying through the spray pipe 400. At this time, the temperature sensor can send the detected temperature information to the control module, which can then control the control valve to start working. The flow sensor can detect the water flow rate of the spray pipe 400, and the control module can control the opening and closing of the control valve according to the flow rate information fed back by the flow sensor. Thus, the opening and closing of the control valve can be flexibly adjusted according to the temperature of the fins. When the fin temperature rises, the water flow rate of the spray pipe 400 can be increased through the control valve, and when the fin temperature drops, the water flow rate of the spray pipe 400 can be decreased through the control valve, thereby making the cooling of the condenser assembly 200 more flexible.

[0049] Reference Figures 1 to 10 In some embodiments, the condensing assembly 200 includes at least two condensers 210, wherein at least one condenser 210 is equipped with a spray assembly; wherein a set of two adjacent condensers 210 are spaced apart at their lower ends to form a water-throwing gap 230, and the water-throwing assembly is located below or at least partially within the water-throwing gap 230. The water-throwing assembly can throw water from the water storage device 300 upwards into the water-throwing gap 230, thereby cooling the two adjacent condensers 210, further improving the cooling effect of the condensing assembly 200, and further improving the cooling effect of the air flowing through the condensers 210.

[0050] Understandably, referring to Figures 1 to 10 In some embodiments, the water-throwing gap 230 between two adjacent condensers 210 gradually decreases from bottom to top, thereby preventing water thrown out by the water-throwing assembly from being directly thrown upward through the water-throwing gap 230 to the outside of the condensing assembly 200. Furthermore, in some embodiments, the condensing assembly 200 also includes an end plate 240, which is disposed at the end of the condenser 210 in the first direction and can block the water-throwing gap 230, thereby preventing water thrown out by the water-throwing assembly from being directly thrown out through both ends of the water-throwing gap 230 to the outside of the condensing assembly 200.

[0051] Understandably, referring to Figures 1 to 10In some embodiments, the condensing assembly 200 includes two condensers 210, with a water-spraying gap 230 between them, and a spray pipe 400 installed on one of the condensers 210. This structure is merely an exemplary illustration of the present invention. In addition to installing the spray pipe 400 on one condenser 210, it is also possible to install the spray pipe 400 on both condensers 210; the present invention does not specifically limit this. Furthermore, the number of condensers 210 in the condensing assembly 200 can be two, three, four, or more. When the number of condensers 210 is three or more, a water-spraying gap 230 can be provided between every two adjacent condensers 210, and a water-spraying assembly can be provided within each water-spraying gap 230; the present invention does not specifically limit this.

[0052] Reference Figures 1 to 10 In some embodiments, the water-throwing assembly includes a water-throwing wheel 500 and a driving device 520. The driving device 520 is installed in the mounting cavity and is connected to the water-throwing wheel 500 in a driving connection. The water-throwing wheel 500 extends downward to the water storage device 300 and upward to the water-throwing gap 230. The driving device 520 can drive the water-throwing wheel 500 to rotate and throw the water in the water storage device 300 upward to the water-throwing gap 230. The outer periphery of the water-throwing wheel 500 is provided with a water-throwing part 510 arranged circumferentially along the water-throwing wheel 500. The thickness of the water-throwing part 510 gradually decreases from the inside to the outside. At least one side surface of the water-throwing part 510 is provided with a plurality of water-throwing grooves 511 arranged sequentially and spaced apart along the circumference of the water-throwing wheel 500. The water-throwing grooves 511 are arc-shaped and extend from the inner end of the water-throwing part 510 to the outer end of the water-throwing part 510. This effectively allows water in the water storage device 300 to be thrown upwards into the water-throwing gap 230 to cool the condenser 210.

[0053] Reference Figures 1 to 4In some embodiments, the water storage device 300 includes a water storage tank 310 and a water receiving trough 320. The water receiving trough 320 is located below the condensing component 200, and the vertical projection of the condensing component 200 is located within the water receiving trough 320. The water-spinning wheel 500 is partially located within the water receiving trough 320, thereby enabling the water in the water receiving trough 320 to be thrown upwards to the condensing component 200 to cool it down. The water receiving trough 320 can effectively collect water droplets falling downwards from the surface of the condensing component 200. The water storage tank 310 is located in the housing and communicates with the water receiving trough 320. A water pump 330 is installed between the spray pipe 400 and the water storage tank 310. One end of the water pump 330 is connected to the water storage tank 310, and the other end is connected to the spray pipe 400. Therefore, the water in the water storage tank 310 can be drawn by the water pump 330 to the spray pipe 400 and sprayed downwards onto the condensation component 200. The water on the condensation component 200 can then flow downwards and drip into the water receiving tank 320, and then flow back into the water storage tank 310 through the water receiving tank 320.

[0054] Reference Figures 1 to 4 In some embodiments, the water storage tank 310 is located below the water receiving trough 320. The water receiving trough 320 is provided with a water outlet pipe 321 that communicates with the water storage tank 310. The bottom wall of the water receiving trough 320 is also provided with a downwardly recessed guide groove 322. The water outlet pipe 321 is located on the side wall of the water receiving trough 320. The guide groove 322 extends to communicate with the water outlet pipe 321, thereby effectively guiding the water in the water receiving trough 320 into the water storage tank 310.

[0055] It is understood that in some embodiments, in order to guide the water in the water receiving tank 320 to the water storage tank 310, in addition to the above-described structure, the water outlet pipe 321 can also be provided on the bottom wall of the water receiving tank 320, and the guide channel 322 can be arranged around the outer periphery of the water outlet pipe 321. This utility model does not specifically limit this.

[0056] Reference Figures 1 to 4 In some embodiments, an installation plate 600 is provided inside the installation cavity. The condenser assembly 200, the fan 100, and the drive device 520 are all installed on the installation plate 600. The water receiving tank 320 is integrally formed on the installation plate 600, and the water storage tank 310 is located below the installation plate 600. This facilitates the installation and assembly of various components inside the housing and makes the structure of the tubeless portable air conditioner more compact and stable.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
