[0002] With the acceleration of modern life rhythm and the significant improvement of people's living quality, air conditioner as the key equipment to provide comfortable indoor environment has been widely applied in the global range. Especially in the popularization in the living and office environment, make air conditioner not only need to meet the basic temperature regulation function, more need to adapt to the individualized demand of different user groups. Although the traditional air conditioner can effectively carry out temperature control on the design, its air supply mode and range are often single, and mainly according to the change of environmental temperature, automatically adjust the air volume, ignore the human comfort and health factor.

[0003] Children and weak user groups are particularly sensitive to the direct blowing of cold or hot air of air conditioner, and are easy to cause cold or other health problems because of the direct blowing of air conditioner wind to the body, and the phenomenon is also called 'air conditioner disease'. This is mainly because the adaptation ability of this kind of user to temperature change is poor, and the air conditioner does not fully consider the position of human body and temperature comfort when air supply, leading to the adverse effect of direct blowing wind on health. The existing air conditioner solution usually adopts the lower air outlet mode in the cooling mode, and adopts the upper air outlet mode in the heating mode, but this fixed air supply direction cannot be flexibly adjusted according to the user demand, which limits the use experience and humanized design of air conditioner.

[0004] In order to solve the above problems, and improve the comfort and health of air conditioner use, some air conditioner products in the market begin to try to adopt more intelligent air supply strategy, for example, by increasing the adjustability of air supply angle, and monitoring the indoor human position by using intelligent sensor, so as to realize directional air supply. However, these solutions are mostly concentrated in the control algorithm and external structure design of air conditioner, and there are few improvements in the air duct structure inside the air conditioner, especially in the small wall-mounted air conditioner, due to the space limitation, it is difficult to realize the complex and reversible air duct design.

[0005] Specifically, the bottom shell air duct profile design of existing air conditioner hanging machine is usually fixed, aiming to ensure the efficiency and effect of single direction air supply. Although this design can meet the basic air supply needs of air conditioner, it has significant technical obstacles in realizing reversible air supply up and down (i.e. realizing upper air outlet in cooling mode and lower air outlet in heating mode). The traditional air duct structure cannot realize flexible conversion of air direction without fundamental modification, which is obviously insufficient for modern users who pursue high customization and comfort. In addition, the drainage system design of traditional air conditioner is also relatively simple, and the drainage and discharge efficiency of condensate water needs to be improved. Especially in high humidity environment, poor discharge of condensate water may cause corrosion of internal components or circuit failure, thereby affecting the service life and safety of air conditioner.

[0006] Therefore, in order to improve the use experience of air conditioner, especially in meeting the needs of children and weak user groups, and to enhance the performance of air conditioner drainage system, it is necessary to innovatively design the internal structure of air conditioner, especially the bottom shell air duct and drainage system, to overcome the limitations of existing technology, realize more flexible air supply mode and more efficient condensate water discharge, so as to improve the comfort and health protection of users while ensuring the basic functions of air conditioner, and prolong the service life of equipment.

Whether the up air outlet is required in the refrigeration mode to avoid the direct blowing of cold air to the human body or the down air outlet is required in the heating mode to promote the uniform distribution of hot air in the room, the direct blowing of cold and hot air to the human body is avoided, the health problems such as cold and air conditioner disease that children and weak user groups may encounter when using the air conditioner are significantly reduced, thereby greatly improving the comfort and safety of the use of the air conditioner, and ensuring that the user can enjoy the most suitable indoor airflow in any season. Meanwhile, the dynamic adjustment of the air door components 30 and the optimized design of the air duct profile help to more accurately control the airflow and reduce unnecessary energy loss, thereby reducing the energy consumption while maintaining high efficiency, achieving the effect of energy saving and emission reduction. The problem that the bottom shell air duct profile design of the existing air conditioner hanging machine is fixed and cannot realize the reversible air supply of up and down is effectively solved.

[0046] As Figure 2 As shown, the air door group further includes an air door connecting rod 40, the air door connecting rod 40 is connected with the multiple air door components 30 to drive the multiple air door components 30 to move synchronously, so as to switch different air duct profiles to form an air outlet channel.

The sliding groove 50 provides a limited path for the movement of the damper link 40, so that the damper link 40 can accurately slide along the predetermined trajectory when driving the damper component 30 to move, thereby ensuring that the damper component 30 is accurately adjusted to the required position in different air supply modes. The provision of the sliding groove 50 reduces the friction of the damper link 40 during movement, ensuring the smoothness of the damper component 30 during swinging, and avoiding the phenomenon of poor damper movement caused by excessive resistance.
