[0074] In addition, it should also be noted that in the description of the present application, unless otherwise specified and limited, the terms "mounting", "setting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0075] The existing technology generally adopts the method of controlling the fan to reverse and realize the reverse air outlet of the fan, so that the indoor unit can realize the purpose of horizontal air supply and vertical air supply at the same time. Since the same air outlet needs to meet the requirements of air inlet and air outlet at the same time, and the appearance of the indoor unit needs to be kept beautiful, the air outlet connecting the indoor unit and the indoor room will be set to a long strip shape, and the width of the air outlet of the fan used in the indoor unit will be larger than the width of the air outlet, so that part of the air outlet of the fan will be blocked near the air outlet, causing turbulence inside the indoor unit, resulting in increased noise and reduced working efficiency of the indoor unit.

[0076] To this end, this application provides a Figures 1 to 19 The indoor unit shown in the figure includes: a shell 1, on which an air outlet is provided; an air outlet assembly 5, which is provided at the air outlet and has an indoor communication port 51 and a fan communication port 52. The indoor communication port 51 is used to communicate with the indoor room. In order to maintain the aesthetics of the indoor unit, the indoor communication port 51 is set to be long and narrow, that is, the length and width of the indoor communication port 51 are relatively large, and the fan communication port 52 is used to communicate with the fan outlet of the indoor unit. The shape of the fan connecting port 52 is the same as that of the fan outlet. In order to ensure the working efficiency of the fan, the fan volute limits the length-to-width ratio of the fan outlet to be much smaller than the length-to-width ratio of the indoor connecting port 51. Therefore, the width of the fan connecting port 52 (the width of the fan outlet) will be greater than the width of the indoor connecting port 51; the wind guide plate 6 is arranged in the air outlet assembly 5, and the wind guide plate 6 can guide the airflow of the fan connecting port 52 to the indoor connecting port 51. By providing the indoor connecting port 51 of the air vent assembly 5 to replace the air vent on the shell 1, the shape of the indoor unit facing the indoor part can be directly adjusted without changing the air vent on the shell 1, thereby improving the aesthetics of the indoor unit while reducing the changes to the shell 1. The wind guide plate 6 in the air vent assembly 5 can also be used to connect the air vent connecting port of the air vent assembly 5 with the fan outlet, so that the fan outlet air flow flows to the indoor connecting port 51 through the fan connecting port 52. At the same time, the wind guide plate 6 can guide this part of the outlet air flow to avoid turbulence in the outlet air flow in the air vent assembly 5, effectively reducing the problem of noise caused by the existence of turbulence in the prior art, and ensuring that all outlet air flows can be smoothly delivered to the room, effectively improving the working efficiency of the indoor unit.

[0077] In order to realize the reversible air supply of the indoor unit, that is, the indoor unit can realize horizontal air supply and vertical air supply at the same time, the air inlet and outlet effects of the air outlet of the indoor unit need to be realized at the same time. Therefore, the air fan return air outlet 53 is further arranged on the air outlet assembly 5, and the return air flow channel is formed between the indoor communication port 51 and the air fan return air outlet 53. The air fan return air outlet 53 of the air outlet assembly 5 can suck the indoor gas into the air fan of the indoor unit through the indoor communication port 51 and the return air flow channel, so as to realize the purpose of air inlet of the indoor unit by the air outlet of the air outlet assembly 5. The indoor unit has a first state in which the air flow passes through the air fan communication port 52 and the indoor communication port 51 in sequence to realize air supply, and a second state in which the air flow passes through the indoor communication port 51 and the air fan return air outlet 53 in sequence to realize air inlet. By using the first state and the second state of the indoor unit, the reversible air outlet of the indoor unit can be realized. The air inlet and outlet directions of the first state of the indoor unit are completely opposite to the air inlet and outlet directions of the second state of the indoor unit. For example, when the indoor unit is in the first state, it is side return air and downward air outlet, and when the indoor unit is in the second state, it is downward return air and side air outlet.

[0078] When the indoor unit is in the first state, the air deflector 6 is in a first position capable of guiding the air flow of the air fan communication port 52 to the indoor communication port 51. At this time, the air flow is blown from the inside of the indoor unit to the indoor communication port 51 through the air fan communication port 52. At this time, the first position of the air deflector 6 is set so that the air deflector 6 can guide the air flow of the air fan communication port 52 to the indoor communication port 51, thereby overcoming the problem that part of the air flow is blocked near the indoor communication port 51 to generate turbulent flow in the prior art, effectively reducing the noise of the indoor unit and improving the working efficiency of the indoor unit.

[0079] When the indoor unit is in the second state, the air deflector 6 is in a second position avoiding the return air flow channel. At this time, the air flow is sucked into the air outlet assembly 5 from the indoor communication port 51 and enters the return air flow channel, that is, the air flow flows from the indoor communication port 51 to the air fan return air outlet 53. At this time, the second position of the air deflector 6 is set so that the air deflector 6 does not block the air flow flowing from the indoor communication port 51 to the air fan return air outlet 53, thereby ensuring the working efficiency of the indoor unit.

[0080] The air deflector 6 can move freely between the first position and the second position. The movement of the air deflector 6 can not only guide the air flow from the fan communication port 52 to the indoor communication port 51, but also avoid the air flow from the indoor communication port 51 to the fan return air port 53, so as to ensure the smooth work of the indoor unit in the first state and the second state. It should be noted that the return air flow channel can be the space between the indoor communication port 51 and the fan return air port 53, and there is no other structure for forming the flow channel. When the air deflector 6 is in the second position, the air deflector 6 is not located between the indoor communication port 51 and the fan return air port 53, so that the air flow can flow smoothly from the indoor communication port 51 to the fan return air port 53 without being blocked by the air deflector 6, thereby reducing the air flow resistance and further improving the working efficiency of the indoor unit.

[0081] As an embodiment, the air port assembly 5 comprises a shell 54, the shell 54 has opposite first and second sides 55 and 56, the indoor communication port 51 is arranged on the first side 55, and the fan communication port 52 and the fan return air port 53 are arranged on the second side 56. The air deflector 6 is rotatably arranged in the shell 54. When the air deflector 6 is in the first position, the air deflector 6 and the shell 54 jointly form an air outflow flow channel, and the indoor communication port 51 and the fan communication port 52 are both communicated with the air outflow flow channel. At this time, the first side 55 of the shell 54 constitutes the side of the indoor unit facing the indoor, and the second side 56 can be connected with the side of the air port of the indoor unit, and the fan communication port 52 is communicated with the fan outlet of the fan in the indoor unit. When the air deflector 6 is in the first position, the air deflector 6 communicates the fan communication port 52 and the indoor communication port 51, that is, the air deflector 6 constitutes a side wall of the air outflow flow channel, so as to force the air flow to flow to the indoor communication port 51, so as to achieve the purpose of guiding the air flow.

[0082] Preferably, the first and second sides 55 and 56 are oppositely arranged, so that the fan communication port 52 and the indoor communication port 51 are also oppositely arranged. When the air deflector 6 is in the first position, the width of the air outflow flow channel gradually decreases from the fan communication port 52 to the indoor communication port 51, so as to realize the purpose of converging the air flow to the indoor communication port 51.

[0083] The housing 54 further includes a third side surface and a fourth side surface located between the first side surface 55 and the second side surface 56. The third side surface and the fourth side surface are disposed opposite each other, and the first end of the air guide plate 6 in the longitudinal direction is sealed to the third side surface, and the second end of the air guide plate 6 in the longitudinal direction is sealed to the fourth side surface. This ensures that the airflow channel is sealed relative to the interior of the housing 54, ensuring that the airflow from the fan connecting port 52 flows through the airflow channel to the indoor connecting port 51. The longitudinal direction of the indoor connecting port 51 is from the third side surface to the fourth side surface.

[0084] A guide block is provided on the third side surface and / or the fourth side surface, and a guide groove is provided on the end face of the air guide plate 6. By utilizing the cooperation of the guide block and the guide groove, the moving path of the air guide plate 6 can be limited, thereby ensuring the reliability of the movement of the air guide plate 6 between the first position and the second position.

[0085] Preferably, the air guide plate 6 is rotatably provided on the first side surface 55, and the air guide plate 6 is located on one side of the indoor connecting port 51. When the air guide plate 6 is in the first position, the free end of the air guide plate 6 abuts against the second side surface 56. At this time, the air guide plate 6 can achieve a sealed partition between the first side surface 55 and the second side surface 56, thereby ensuring the sealing of the air outlet air flow channel relative to the interior of the outer shell 54; when the air guide plate 6 is in the second position, the air guide plate 6 is attached to the first side surface 55, and the air guide plate 6 will not hinder the flow of air from the indoor connecting port 51 to the fan return air outlet 53.

[0086] In order to realize automatic control of the air guide plate 6, the indoor unit also includes a driving structure 7, which is transmission-connected to the air guide plate 6, and the driving structure 7 can drive the air guide plate 6 to move between the first position and the second position. Through the action of the driving structure 7, the air guide plate 6 is automatically adjusted according to the working mode of the indoor unit.

[0087] The indoor unit also includes: a fan 2, which is arranged in the shell 1, and the fan 2 has a fan air inlet 21 and a fan air outlet, and the fan air outlet is connected to the fan connecting port 52; when the indoor unit is in the first state, the air flow is discharged from the indoor unit through the fan air outlet, the fan connecting port 52 and the indoor connecting port 51, and the indoor unit now realizes the first mode of supply and return air state, for example, it can be side return air and lower air outlet; when the indoor unit is in the second state, the air flow enters the fan 2 through the indoor connecting port 51, the fan return air port 53 and the fan air inlet 21, and the indoor unit now realizes the second mode of supply and return air state, for example, it can be lower return air side outlet.

By arranging the avoiding area 31 on the filter structure 3, the fan outlet of the fan 2 can be directly communicated with the fan communication port 52 through the avoiding area 31, when the fan communication port 52 serves as an air outlet, the filter structure 3 will not hinder the air outlet of the fan outlet, ensuring the air outlet effect of the indoor unit, and the filter structure 3 also has a filtering area, so that the fan inlet 21 can only be communicated with the fan communication port 52 through the filtering area, when the fan communication port 52 serves as an air inlet, the gas must be filtered through the filtering area before entering the indoor unit, so as to ensure the working reliability of the indoor unit.

[0089] The filter structure 3 comprises a frame and a filter screen arranged on the frame, the filter screen is not arranged at the frame corresponding to the avoiding area 31, and the filter screen is arranged at the frame corresponding to the filtering area.
