The swing blade 21 may further include a middle section 213, where the middle section 213 is used to smoothly connect the first end 211 with the second end 212, and the middle section 213 is connected with the rotating shaft 22.
The swing blade 21 has a substantially oblong curved plate shape. The two ends along the length thereof are a first end 211 and a second end 212, respectively. The height difference between the first end 211 and the second end 212 may be set according to actual needs. For example, the difference in height between the first end 211 and the second end 212 may be 20mm or more and 30mm or less, for example, the difference in height between the first end 211 and the second end 212 may be 20mm or 21mm or 22mm or 23mm or 24mm or 25mm or 26mm or 29mm or 30mm, or a quota value between any two of the above. Of course, the specific value of the height difference between the first end 211 and the second end 212 is not limited thereto, and the present embodiment is merely illustrated herein.
For example, since the hot air generally flows upward, when the indoor air conditioner needs to be warmed in winter with relatively low outdoor temperature, the second end 212 with relatively low temperature can be arranged closer to the air outlet 11, so as to guide the air flow with relatively low temperature output by the indoor air conditioner downward. The cool air generally goes down, so that when the air conditioner indoor unit is required to cool in summer with lower outdoor temperature, the relatively higher first end 211 can be arranged closer to the air outlet 11, which is beneficial to guiding the relatively lower temperature air flow output by the air conditioner indoor unit upwards.
Optionally, the width of the first end 211 and the second end 212 of the pendulum blade 21 is smaller than the width of the intermediate section 213. That is, the width of the swing blade 21 can be set to be wider at the position where the air volume of the air outlet 11 is larger and the air speed is faster, and the width of the swing blade 21 can be set to be narrower at the position where the air volume of the air outlet 11 is smaller and the air speed is slower, so that the production cost can be saved while ensuring that the swing blade 21 has a better air guiding effect.
Alternatively, the first end 211 of the swing blade 21 is bent, and the first end 211 is disposed to protrude upward along the middle of the length direction of the swing blade 21. The second end 212 of the swing blade 21 is bent, and the second end 212 is recessed along the middle of the length direction of the swing blade 21. Therefore, the air flow is favorably guided to a plurality of directions at the same time, so that the air flow output by the air conditioner indoor unit is more dispersed and softer.
The bending angle of the middle portion of the first end 211 may be greater than or equal to 30 degrees and less than or equal to 45 degrees. Alternatively, the bending angle of the middle part of the first end 211 may be 30 degrees, 35 degrees, 40 degrees, or 45 degrees, and the bending angle of the middle part of the first end 211 may also be a value between any two of the above. Of course, the specific value of the bending angle of the middle portion of the first end 211 is not limited thereto, and the present embodiment is only illustrated herein.
Accordingly, the bending angle of the middle portion of the second end 212 may be greater than or equal to 30 degrees and less than or equal to 45 degrees. Alternatively, the bending angle of the middle portion of the second end 212 may be 30 degrees, 35 degrees, 40 degrees, or 45 degrees, and the bending angle of the middle portion of the second end 212 may be a value between any two of the above. Of course, the specific value of the bending angle of the middle portion of the second end 212 is not limited thereto, and the present embodiment is only illustrated herein.
The bending angle of the middle portion of the first end 211 may be equal to the bending angle of the middle portion of the second end 212, or the bending angle of the middle portion of the first end 211 may be smaller than the bending angle of the middle portion of the second end 212, or the bending angle of the middle portion of the first end 211 may be larger than the bending angle of the middle portion of the second end 212.
Optionally, the middle section 213 of the swing blade 21 is also inclined, and the middle section 213 of the swing blade 21 is gradually inclined downward from the first end 211 toward the second end 212, so as to facilitate the user to quickly sense the cold or heat.
Optionally, the center line of the swing blade 21 along the axial direction of the rotating shaft 22 is overlapped with the center line of the rotating shaft 22, which is beneficial to ensuring the motion stability.
In addition, in this embodiment, a sliding plate may be further disposed at the air outlet 11, and the sliding plate is used for opening or closing the air outlet 11.
The embodiment also provides an air conditioner, which comprises an air conditioner external unit and an air conditioner internal unit which are connected. An air conditioner outdoor unit generally includes an outdoor heat exchanger, and an air conditioner indoor unit generally includes an indoor heat exchanger, a throttle device, and a compressor. When the air conditioner performs refrigeration, the compressor compresses a gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the outdoor heat exchanger for cooling, the high-temperature high-pressure gaseous refrigerant is cooled and then becomes a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled and depressurized by the throttling device to become a low-temperature low-pressure gas-liquid mixture, and the low-temperature low-pressure gas-liquid mixture is vaporized into a gaseous state by absorbing heat in air by the indoor heat exchanger, so that the refrigeration effect is achieved; the gaseous refrigerant returns to the compressor to continue compression, and the circulation is continued to perform refrigeration. The air conditioner indoor unit comprises a cabinet air conditioner and an air conditioner hanging machine, and the cabinet air conditioner is widely applied due to strong wind power, convenient installation and the like.
