[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a multi-split air conditioning system technical solution: it includes an outdoor unit 1 and three indoor units 2. The outdoor unit 1 and each indoor unit 2 are connected by refrigerant pipes 3. The outdoor unit 1 includes a compressor and a condenser, which are connected sequentially by refrigerant pipes 3. The indoor unit 2 includes an indoor unit housing 21, an evaporator, and an air guide assembly 4. The evaporator and the air guide assembly 4 are both disposed inside the indoor unit housing 21. The air guide assembly 4 includes an outer mounting plate 5, an inner mounting plate 6, an air guide duct 7, and a drive assembly 8. A cold air channel 9 is provided between the outer mounting plate 5 and the inner mounting plate 6. The cold air channel 9 is connected to the air outlet of the indoor unit 2. Several sets of air guide ducts 7 are provided. The air guide ducts 7 are movably mounted on the outer mounting plate 5 through a ball-type connecting assembly 10. One end of the air guide duct 7 is located inside the cold air channel 9, and the other end is located outside the outer mounting plate 5. The drive assembly 8 is mounted on the inner mounting plate 6, and one end of the drive assembly 8 is connected to one end of the air guide duct 7.

[0021] Furthermore, the spherical connection assembly 10 includes a ball head seat 11 and a ball head sleeve 12. The ball head seat 11 is fixedly installed on the outside of the air duct 7, and the ball head sleeve 12 is fixedly installed on the outer mounting plate 5. The ball head seat 11 is installed inside the ball head sleeve 12, and the ball head seat 11 and the ball head sleeve 12 are movably connected.

[0022] In this embodiment, the drive component 8 is driven by a motor. The motor is connected to one end of the air duct 7 located in the cold air channel 9 through a transmission structure. When the motor starts, it can drive the air duct 7 to rotate around the spherical connecting component 10, thereby changing the air outlet direction of the air duct 7, realizing multi-angle air supply, and meeting the cooling needs of different areas.

[0023] Furthermore, the drive assembly 8 includes a drive motor 13, a rocker arm 14, and a connecting rod 15. The drive motor 13 is fixedly mounted on the inner mounting plate 6, and the output end of the drive motor 13 is fixedly connected to the rocker arm 14. The connecting rod 15 is fixedly mounted on one end of the air duct 7, and the other end of the connecting rod 15 is movably connected to the rocker arm 14.

[0024] In this embodiment, when the drive motor 13 starts, its output will drive the rocker arm 14 to rotate. Since one end of the connecting rod 15 is fixedly installed on the air duct 7 and the other end is movably connected to the rocker arm 14, the rotation of the rocker arm 14 will drive the connecting rod 15 to swing, thereby driving the air duct 7 to rotate around the spherical connecting assembly 10. This structure allows the air outlet direction of the air duct 7 to be flexibly adjusted as needed, thereby achieving multi-angle air supply, effectively meeting the cooling needs of different areas, and improving the cooling efficiency and comfort of the air conditioning equipment.

[0025] Furthermore, a connecting ball 16 is fixedly installed at the connection end of the connecting rod 15 and the rocker arm 14, and a connecting ring 22 is fixedly installed on the rocker arm 14, with the connecting ring 22 sleeved on the outside of the connecting ball 16.

[0026] Furthermore, the air duct 7 has a vent 17 at one end located inside the cold air channel 9, and an air outlet 18 at the other end.

[0027] In this embodiment, the ventilation opening 17 at one end of the air duct 7 located inside the cold air channel 9 allows cold air to smoothly enter the air duct 7.

[0028] Furthermore, the air duct 7 is driven by an independent drive motor 13 to control the adjustment of the air outlet angle.

[0029] Furthermore, the indoor unit 2 is also equipped with a temperature sensor 19 and a controller 20. The temperature sensor 19 is installed inside the indoor unit housing 21 and is used to detect the indoor ambient temperature and transmit the temperature signal to the controller 20.

[0030] Furthermore, the controller 20 is electrically connected to the compressor and the drive motor 13 respectively. The controller 20 controls the operating frequency of the compressor and the rotation of the drive motor 13 according to the temperature signal detected by the temperature sensor 19, thereby realizing precise adjustment of indoor temperature and flexible control of the air outlet angle of the air duct 7.

[0031] Working Principle: When this multi-split air conditioning unit starts working, the compressor in the outdoor unit 1 starts, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant 3. The refrigerant then enters the condenser for heat dissipation, becoming a high-temperature, high-pressure liquid refrigerant. The liquid refrigerant is then transported to each indoor unit 2 through refrigerant pipes. Inside the indoor unit, the liquid refrigerant enters the evaporator, absorbing heat from the indoor air and evaporating into a low-temperature, low-pressure gaseous refrigerant. Simultaneously, the air around the evaporator is cooled, forming cool air. The controller 20 controls the rotation of the drive motor 13 in the corresponding indoor unit 2. After the drive motor 13 starts, it drives the rocker arm 14 to rotate. The rocker arm 14, through the cooperation of the connecting rod 15, connecting ball 16, and connecting ring 22, drives the air duct 7 to rotate around the spherical connecting assembly 10, adjusting the air outlet angle of the air duct 7. After the cold air exits the evaporator, it enters the air duct 7 through the cold air channel 9, and is then blown out from the air outlet 18 on the air duct 7, blowing towards different areas of the room to achieve multi-angle air delivery and make the indoor temperature drop quickly and evenly. When the indoor temperature reaches the preset temperature, the controller 20 will control the compressor to reduce its operating frequency to reduce energy consumption.
