Technical Field

Background
In the conventional air conditioning industry, air conditioners may be classified into a heater focusing on heating and a refrigerating air conditioner focusing on refrigerating. Although both air conditioners can cool and heat, due to the structural characteristics and the influence of the hanging height, each air conditioner can only achieve a better effect on one mode in the cooling or heating process, and cannot achieve the effects of the cooling mode and the heating mode.
For the refrigerating air conditioner, the air outlet is arranged on the upper side of the air conditioner, and the hanging height of the refrigerating air conditioner is higher, so that cold air discharged from the air conditioner is sprayed upwards at a higher starting point and descends, thereby rapidly covering the area in a room and achieving better refrigerating effect. However, when it is used for heating, hot air is also ejected upward from a higher position and rises to the top of the room, which results in that the hot air cannot quickly cover the area of the bottom in the room, and the heating effect is deteriorated.
For the heating air conditioner, the air outlet is arranged at the lower side of the air conditioner, and the hanging height of the heating air conditioner is lower, so that hot air discharged from the air conditioner is sprayed downwards at a lower starting point and rises, thereby rapidly covering the area in a room and achieving a better heating effect. However, when it is used for cooling, the cool air is also sprayed downwards from a lower position and descends to the bottom of the room, which causes that the cool air cannot rapidly cover the middle and upper areas of the room, and the cooling effect is deteriorated.
Therefore, the air outlet position of the air outlet of the air conditioner in the prior art is difficult to adjust, so that the air conditioner in the prior art cannot achieve both the refrigerating effect and the heating effect.
