[0023] Figure 8 This is an assembly diagram of Embodiment 2 of this utility model. Detailed Implementation

[0024] This utility model is a bladeless portable air conditioner, such as Figures 1 to 8 As shown, the device includes a cylindrical housing 1, a compressor 2, a condenser 3, a lower air duct assembly 4, an evaporator 5, an upper air duct assembly 6, and an air outlet frame 7. Their structure and working principle are basically the same as those of commonly used portable air conditioners. The difference is that it also includes a horizontal rotation drive structure 8 for the air outlet frame; a horizontal air outlet 71 is provided on the air outlet frame 7; the horizontal rotation drive structure 8 is located in the upper part or upper outer part of the housing 1, driving the air outlet frame 7 to rotate horizontally to deliver air 360 degrees. This allows the cool air blown by the air conditioner to be delivered more evenly and quickly throughout the entire indoor space, resulting in a more uniform cooling effect and improving the user experience. Therefore, the structure of this invention is more reasonable. No blades are needed inside the air outlet frame 7 for air guidance.

[0025] In embodiments one and two, the compressor 2, condenser 3, lower air duct assembly 4, and evaporator 5 are all housed within the casing 1. The difference between these two embodiments is that the upper air duct assembly 6 is housed either within the casing 1 or within the air outlet frame 7, depending on whether the impeller outlet of the upper air duct assembly 6 is vertically upward or horizontally downward.

[0026] In Example 1, as Figures 1 to 6 As shown, the upper air duct assembly 6 is located inside the upper part of the housing 1, with its impeller outlet 61 pointing vertically upward (at this time, its impeller shaft is parallel to the ground, and the air blown by the impeller is upward), and the airflow is directly aligned with the opening at the lower part of the air outlet frame 7. Here, the air outlet 71 of the air outlet frame 7 is a vertical annular air outlet, with two outlets, one in front and one behind, located on the air outlet frame, as shown. Figure 2 As shown.

[0027] In Example 2, as Figure 7 , 8 As shown, the upper air duct assembly 6 is located inside the air outlet frame 7, and its impeller air outlet 61 is arranged horizontally (at this time, its impeller shaft is perpendicular to the ground, and the air blown out by the impeller is horizontal); the air outlet 71 of the air outlet frame 7 is a vertically arranged grid hole, which is aligned with the impeller air outlet 61.

[0028] In Examples 1 and 2, as Figure 3 As shown, the horizontal rotation drive structure 8 of the air outlet frame includes a fixed base 81, a planar rotary bearing 82, a gear ring 83, a drive gear 84, and an oscillating motor 85. The fixed base 81 is installed and fixed to the upper end of the housing 1; the planar rotary bearing 82 is disposed in the bearing mounting groove 811 of the fixed base 81; the gear ring 83 is disposed on the planar rotary bearing 82; the drive gear 84 is installed on the motor shaft of the oscillating motor 85; after the oscillating motor 85 is installed and fixed to the fixed base 81, the drive gear 84 meshes with the gear ring 83 for transmission; in Embodiment 1, the air outlet frame 7 is fixedly connected to the gear ring 83; in Embodiment 2, the upper air duct assembly 6 is fixedly connected to the gear ring 83; the air outlet frame 7 is fixedly connected to the upper air duct volute 62 of the upper air duct assembly 6. Preferably, a plurality of pressure blocks 86 are provided at intervals on the fixed base 81 to prevent the gear ring 83 from vibrating up and down and shifting horizontally. These blocks press against the surface of the gear ring 83 to prevent it from jumping upwards, and the arc surfaces (here, the outer arc surfaces) of the multiple pressure blocks 86 are used to confine the gear ring 83 to rotate horizontally within a circumference to reduce frictional resistance, thereby ensuring reliable and smooth meshing transmission between the gear ring 83 and the drive gear 84.

[0029] In this embodiment, as Figure 4 As shown, the lower duct assembly 4 includes an upper volute 41, a lower impeller 42 disposed within the upper volute 41, a lower duct motor 43 disposed on the upper volute 41, and a lower volute 44 fixed together with the upper volute 41; a water tank 441 (and a water tank cover 442) is provided on the lower volute 44; as shown... Figure 2As shown, a water receiving tray 11 is located inside the housing 1, below the evaporator 5. The water receiving tray 11 has a water inlet 111 that directs water downwards into a water tank 441. Multiple drip holes 4411 are evenly distributed above the top of the condenser 3 in the water tank 441, allowing some of the condensate dripping onto the condenser to evaporate automatically, thus improving cooling performance. Incompletely evaporated condensate flows into the bottom plate 12 of the housing 1. Therefore, a water storage box 121 and a water pump motor 122 with a water pump wheel 125 are provided on the bottom plate 12 of the housing 1, allowing the water in the water storage box 121 to be pumped back onto the condenser by the water pump motor 122 for evaporation, thereby improving the air conditioner's cooling effect. Preferably, a drain pipe 123 is provided on the bottom plate 12, allowing all incompletely evaporated water to drain away. A cover 124 is provided on the bottom plate 12 to cover the power cord 9 to prevent condensate from flowing onto the air conditioner's power cord.

[0030] In this embodiment, the housing 1 includes a bottom plate 12, a semi-circular front panel 13, and a rear panel 14; a filter screen 15 is provided on the rear panel 14.
