According to an embodiment of the present invention, referring to fig. 8 to 11, the return air valve 150 includes a door body 151 and a driving motor 152. The door 151 is rotatably disposed in the return duct 140 to open or close the door 151. When the air conditioner is in a return air mode, the door 151 is in an open state, air flow can flow in the return air pipeline 140, the air flow in the fresh air pipeline 122 flows from the indoor to the outdoor to blow out accumulated dust in the fresh air pipeline 122, and at the moment, the return air pipeline 140 can balance air pressure inside and outside the fresh air module 120, so that the air flow in the fresh air pipeline 122 can flow more smoothly; when the air conditioner is in the fresh air mode, the door 151 is in the closed state, the air return pipeline 140 is in the disconnected state, and the airflow can flow from the outdoor to the indoor through the fresh air pipeline 122. The driving motor 152 is connected to the wall surface of the fresh air chamber 1211, and the driving motor 152 is connected to the door 151 to drive the door 151 to rotate, so that the door 151 can be smoothly switched between the open state and the closed state.
According to an embodiment of the present invention, referring to fig. 1 and 4, the indoor unit 100 of the air conditioner may further include a fresh air valve 160. The fresh air valve 160 is disposed in the fresh air pipeline 122, and the fresh air valve 160 is located between a connection portion of the fresh air pipeline 122 and the air return pipeline 140 and an end portion of the fresh air pipeline 122 communicated with the fresh air chamber 1211. When the air conditioner is used, when the fresh air module 120 is in the fresh air mode, the fresh air valve 160 is in an open state, and in the airflow flowing direction, the airflow can sequentially flow through the connection part of the fresh air pipeline 122 and the air return pipeline 140, the fresh air valve 160, and the end part of the fresh air pipeline 122 communicated with the fresh air chamber 1211, and then reach the fresh air chamber 1211, and is blown out from the fresh air outlet 12111, so that the fresh air can enter the indoor environment.
When the fresh air valve 160 is in the closed state, the fresh air valve 160 can separate the indoor environment from the outdoor environment, so as to provide a good sealing effect for the indoor unit 100 of the air conditioner. For example, in hot summer, the fresh air valve 160 is closed, so that hot and humid air outside the room can be prevented from entering the room; when the weather is cold in winter, the outdoor temperature is lower, and outdoor cold air receives the effect of pressure, can enter into indoor environment through fresh air pipeline 122, and through setting up new trend valve 160, can prevent that cold air from entering into indoor environment.

From this, the arc not only can produce the aesthetic feeling in the vision, can also bear great amount of wind simultaneously for the air current can blow off from fresh air pipeline 122 fast, because the air current rushes out fresh air pipeline 122 under the effect of pressure, can produce great wind speed, and then replaces indoor air to the at utmost, thereby satisfies the needs that indoor new trend was taken a breath, can also clean the deposition in the outdoor fresh air pipeline 122 effectively, and can solve the too good problem of indoor leakproofness.
Further, the other end of the air return pipeline 140 is arranged at the fresh air outlet 12111, so that the length of the air return pipeline 140 can be prolonged, the flow path of the air flow in the air return pipeline 140 can be further prolonged, the pressure difference inside and outside the fresh air module 120 is easily balanced, and the air return effect can be further improved.
According to an embodiment of the present invention, referring to fig. 4 to 5, the fresh air module 120 includes an air intake housing 121, a volute component 124 and a fresh air blower. The fresh air chamber 1211 is defined in the air inlet casing 121, and the outdoor air firstly enters the fresh air chamber 1211 through the fresh air pipeline 122, so that the air flow can be rectified, the vortex generated in the air flow flowing process is reduced, the noise of the air flow flowing can be reduced, and the mute effect of the air-conditioning indoor unit 100 can be improved. Further, by providing the fresh air chamber 1211, a filter device may be provided in the fresh air chamber 1211.

In some examples, the fresh air blower may be disposed within the volute assembly 124 to provide power for the airflow to smoothly flow within the fresh air duct 123. Further, the fresh air fan is a centrifugal fan, an axial flow fan or a counter-rotating fan.
When the fresh air fan is a centrifugal fan, the fresh air module 120 may adopt a centrifugal air duct, and the centrifugal fan accelerates the air by using an impeller rotating at a high speed according to the principle that kinetic energy is converted into potential energy, and then decelerates and changes the flow direction, so that the kinetic energy is converted into the potential energy.
When the fresh air fan is an axial flow fan, the fresh air module 120 can adopt an axial flow air duct, the axial flow air duct has the advantages of large air volume and low noise, when the axial flow fan rotates reversely, reverse air supply can be directly realized, indoor air is blown to the outdoor through the axial flow fan and the fresh air pipeline 122, the reverse air supply of the axial flow fan can effectively clean dust, sundries and the like in the outdoor section of the fresh air pipeline 122, when the indoor tightness of a user is good, the axial flow fan can rotate reversely to discharge indoor dirty air out of the outdoor firstly, and after the indoor air pressure is reduced, the axial flow fan rotates forwards to introduce outdoor fresh air into the indoor.
When the fresh air fan is a counter-rotating fan, the fresh air module 120 may adopt a counter-rotating axial flow air duct, which is an air duct formed by two axial flow impellers with the same diameter, the same hub ratio and the opposite rotating directions connected in series front and back. The two impellers are generally driven by two motors, but the rotation speeds of the two impellers can be different. The axial size of the counter-rotating axial flow air channel is small, because the counter-rotating axial flow fan is formed by connecting two impellers with opposite rotating directions in series, the air flow transmitted by the first-stage impeller is just reversely rotated by the second-stage impeller to be eliminated, and the axial flow meeting the outlet requirement of the fresh air fan is directly generated. In addition, the counter-rotating axial flow fan has good counter-wind performance, and the counter-wind purpose can be effectively achieved only by changing the rotation direction of the impeller in the work of the counter-rotating axial flow fan, so that the counter-wind structure of the fresh air fan is the simplest and the simplest when in use.
