Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator.

The angle between the first and second passages 2221, 2222 is 90 deg.. For example, when the switching device 222 rotates from the first communication position to the second communication position, the switching device 222 may rotate 90 ° counterclockwise at this time, so as to communicate the air duct switching air inlet 2211 with the second air duct switching air outlet 2213, and reduce the wind resistance of the fresh air in the first channel 2221 and the second channel 2222, so that the fresh air can be blown into the room quickly.
According to a further embodiment of the present invention, the fresh air duct switching device 22 further includes a motor 223, and the motor 223 is connected to the switching device 222 to drive the switching device 222 to rotate between the first communication position and the second communication position. For example, in the example of fig. 7 and 10, the motor 223 may be located on a side of the fresh air duct switching housing 221 away from the heat exchanger 4, an output shaft of the motor 223 is connected to the switching device 222, and when the switching device 222 is switched between the first communication position and the second communication position, the output shaft of the motor 223 rotates to drive the switching device 222 to rotate, so that the switching device 222 can rotate between the first communication position and the second communication position.
In some optional embodiments, the stepping motor 5 is disposed on one side of the first fresh air outlet duct 12 and one side of the second fresh air outlet duct 13 in the length direction, and the stepping motor 5 can rotate the first fresh air outlet 121 or the second fresh air outlet 131 to different air supply angles. When the indoor unit 100 of the air conditioner operates in a cooling mode, the first fresh air outlet 121 can rotate to a first air supply angle (as shown in fig. 3), and at the moment, air at the first fresh air outlet 121 flows upwards, so that cold air can be prevented from blowing directly to a user; alternatively, the first fresh air outlet 121 may rotate to a second air supply angle (as shown in fig. 4), at this time, the air at the first fresh air outlet 121 flows downward, and the flow direction of the air at the first fresh air outlet 121 is parallel to the flow direction of the cool air at the air outlet 14, so as to prolong the air supply distance of the cool air. When the indoor unit 100 of the air conditioner is in heating operation, the second fresh air outlet 131 can rotate to a third air supply angle (as shown in fig. 5), air at the second fresh air outlet 131 flows downwards, and the flow direction of the air at the second fresh air outlet 131 is parallel to the flow direction of hot air at the air outlet 14, so that the air supply distance of the hot air can be prolonged; or, the second fresh air outlet 131 may rotate to a fourth air supply angle (as shown in fig. 6), and at this time, the flow direction of the air at the first fresh air outlet 121 faces the hot air at the air outlet 14, so as to guide the hot air at the air outlet 14, so that the hot air can be blown to the user as much as possible.
Alternatively, the switching device 222 may be a two-way valve.
