[0042] Figure 1 Figure 1 is a cross-sectional view of the air conditioner indoor unit of an embodiment of the present application, referring to Figures 2 to 7 The air conditioner indoor unit of the embodiment of the present application includes a housing 10 and a switch plate 30.

[0043] The front side of the housing 10 is provided with a first air outlet 13 and a second air outlet 14, and the housing is provided with an air outlet air duct 15 and a bypass air duct 16. The air outlet end of the air outlet air duct 15 is the first air outlet 13, the air outlet end of the bypass air duct 16 is the second air outlet 14, and the air inlet end of the bypass air duct 16 is connected to the air outlet air duct 15.

[0044] The switch plate 30 is provided with a communication hole 31; the plane where the air inlet end of the bypass air duct 16 is located is a first plane, and the switch plate 30 is always on the first plane when it is working, and is movably arranged at the air inlet end of the bypass air duct 16 to change the included angle between the axis of the communication hole 31 and the first plane.

[0045] In the embodiment, the shell is provided with the first air outlet 13, the second air outlet 14, the air outlet air duct 15 and the bypass air duct 16, and the switch plate 30 is arranged between the air outlet air duct 15 and the bypass air duct 16. By rotating the switch plate 30, the difficulty of air inlet and / or air outlet of the bypass air duct can be changed, and even the air inlet end of the corresponding switch plate position of the bypass air duct is completely closed, so as to close the bypass air duct. Therefore, the air conditioner indoor unit has multiple air outlet modes. For example, the first air outlet 13 can be selected to outlet air, or the second air outlet 14 can be selected to outlet air, or the first air outlet 13 and the second air outlet 14 can be selected to outlet air at the same time. The air conditioner indoor unit not only increases the adjustment range of the air outlet angle, but also increases the adjustment range of the air outlet volume. Multiple air outlet modes can meet the needs of users, thereby improving the comfort of the air conditioner indoor unit.

[0046] Further, in some optional embodiments of the present application, the switch plate is rotatably arranged around an axis perpendicular to the plane where the air inlet end of the bypass air duct is located, that is, the switch plate is rotatably arranged around an axis perpendicular to the first plane. In some alternative embodiments of the present application, the switch plate is rotatably arranged around an axis parallel to the plane where the air inlet end of the bypass air duct is located, that is, the switch plate is rotatably arranged around an axis parallel to the first plane.

[0047] Further, the size of the switch plate can be designed according to the needs, which can be divided into the following three cases:

[0048] The first case: there is one switch plate 30 with a large size, and when the switch plate 30 is in the first plane, the edge of the switch plate 30 coincides with the inlet edge of the bypass air duct 16. At this time, by changing the angle between the axis of the communication hole 31 and the first plane, the inlet of the bypass air duct 16 can be completely closed.

[0049] The second case: there is one switch plate 30 with a small size, and when the switch plate 30 is in the first plane, the edge of the switch plate 30 partially coincides with the inlet edge of the bypass air duct 16. At this time, by changing the angle between the axis of the communication hole 31 and the first plane, the inlet of the bypass air duct 16 can be partially closed.

[0050] The third case: there are multiple switch plates 30, and the size of the switch plate 30 is small. By rotating part of the switch plates 30, the inlet of the bypass air duct 16 can be partially closed, or by rotating all the switch plates 30 at the same time, the inlet of the bypass air duct 16 can be completely closed. By selecting different combinations of the number of switch plates, the air inlet volume of the bypass air duct 16 can be adjusted.

[0051] In some alternative embodiments of the present application, the switch plate 30 has a first position (as shown in Figure 3 and a second position (as shown in Figure 2 ).

[0052] The communication hole has a first end facing the bypass air duct and a second end facing the air outlet air duct. As shown in Figure 3 , in the first position, the first end is in front of the second end; as shown in Figure 2 , in the second position, the first end is behind the second end.

[0053] Specifically, as shown in Figure 3 , when the switch plate 30 is in the first position, the air outlet air duct 15 and the bypass air duct 16 are in communication, the airflow in the air outlet air duct 15 enters the bypass air duct 16 through the communication hole 31, and the second air outlet 14 can send air to the room. As shown in Figure 2 , when the switch plate 30 is in the second position, the air outlet air duct 15 and the bypass air duct 16 are not in communication, and at this time the second air outlet 14 cannot send air to the room.

[0054] In this embodiment, by changing the position of the switch plate 30 and the opening and closing of the first air outlet 13, the air conditioner indoor unit can have the following air outlet modes:

[0055] The first air outlet mode: when the switch plate 30 is in the first position, if the first air outlet 13 is closed, the airflow in the air outlet air duct 15 all flows into the bypass air duct 16 and flows to the second air outlet 14, that is, at this time only the second air outlet 14 sends air to the room.

[0056] The second air outlet mode: when the switch plate 30 is in the first position, if the first air outlet 13 is opened, part of the airflow in the air outlet air duct 15 flows into the bypass air duct 16 and flows to the second air outlet 14, and the other part of the airflow in the air outlet air duct 15 flows to the first air outlet 13, that is, at this time the first air outlet 13 and the second air outlet 14 can send air to the room at the same time.

[0057] The third air outlet mode: when the switch plate 30 is in the second position, if the first air outlet 13 is opened, the airflow in the air outlet air duct 15 all flows to the first air outlet 13, that is, at this time only the first air outlet 13 sends air to the room.

[0058] In addition, when the switch plate 30 is in the second position, if the first air outlet 13 is closed, at this time the first air outlet 13 and the second air outlet 14 do not send air to the room.

[0059] In some alternative embodiments of the present application, the second air outlet 14 is a micro air outlet.

[0060] Specifically, the air outlet end of the bypass air duct is provided with a micro-wind panel to form the micro-wind outlet. The micro-wind panel is uniformly provided with a plurality of small openings.

[0061] In the embodiment, the wind delivered by the bypass air duct is scattered by the micro-wind panel to become micro-wind, so that the air outlet of the second air outlet is softer, and the air outlets of the first air outlet and the second air outlet are different, thereby further meeting the differentiated air supply needs of the user. The air conditioner has a micro-wind mode, a micro-wind + conventional wind mode, and a conventional wind mode.

[0062] In some optional embodiments of the present application, the communication hole is a micro-hole.

[0063] In the embodiment, the micro-hole can scatter the airflow to become micro-wind, so that the air outlet of the second air outlet is softer.

[0064] In some optional embodiments of the present application, the air inlet end of the bypass air duct 16 extends along a preset direction. As shown in the figure, the switch plate is a plurality of, and a plurality of switch plates are arranged along the preset direction. A plurality of switch plates move synchronously. In some alternative embodiments of the present application, or at least one of the switch plates moves individually. Figures 4-6

[0065] Specifically, when a plurality of switch plates move synchronously, it is convenient to realize the complete closure of the inlet of the bypass air duct 16. When at least one switch plate moves individually, a plurality of switch plates can move asynchronously, which is convenient for adjusting the closure range of the inlet of the bypass air duct 16, and can realize complete closure or partial closure of the inlet of the bypass air duct 16.

[0066] In some optional embodiments of the present application, the air conditioner indoor unit further comprises a driving mechanism 50 and a fixed rod 40 extending along a preset direction.

[0067] The driving mechanism is used to drive the switch plate to move. The switch plate 30 is a circular plate, and the center of the circular plate is rotatably installed on the fixed rod 40.

[0068] The driving mechanism 50 comprises a motor 51, a connecting rod 52 and a connecting shaft 53. The motor 51 comprises an output shaft; the connecting rod 52 is vertically arranged, one side of the circular plate is rotatably installed on the connecting rod 52; one end of the connecting shaft 53 is installed on the output shaft, and the other end is rotatably connected with the connecting rod.

[0069] Specifically, one side of the circular plate is rotatably installed on the connecting rod 52 through a connecting portion 54. As shown in the figure, the output shaft of the motor 51 can drive the connecting shaft 53 to rotate. The position of the fixed rod 40 is fixed. Figure 6

[0070] ​​The working principle of the driving mechanism is that the output shaft of the motor 51 drives the connecting rod 52 to rotate through the connecting shaft 53, thereby driving the circular plate to rotate around the center thereof, so as to switch the switch plate between the first position and the second position. During the switching between the first position and the second position, the rotation angle of the circular plate is 180°.

[0071] In some optional embodiments of the present application, the first air outlet 13 and the second air outlet 14 both extend in the vertical direction.

[0072] In the present embodiment, the above arrangement can avoid indoor temperature stratification, so that the indoor temperature is uniform in the up-down direction.

[0073] In some optional embodiments of the present application, the first air outlet is two, which are symmetrically arranged about a vertical reference surface extending in front and back; and the second air outlet is two, which are symmetrically arranged about the reference surface.

[0074] In the present embodiment, by arranging two first air outlets and two second air outlets, the air supply angle range and the air supply volume range of the air conditioner indoor unit can be further expanded, and the air supply mode can be more diversified. For example: ① only two first air outlets blow air; ② only two second air outlets blow air; ③ one first air outlet and one second air outlet blow air; ④ two first air outlets and two second air outlets blow air at the same time.

[0075] Further, the air conditioner indoor unit further comprises an air guiding interval 20 arranged between the two first air outlets 13 and between the two second air outlets 14.

[0076] In the present embodiment, when the two first air outlets and / or the two second air outlets blow air forward, the air in the air guiding interval 20 is driven to flow forward by the negative pressure, so that the air is mixed with the air blown out of the air outlets. In cooling, the air temperature is improved, so that the air is not too hard, and a soft air effect is achieved.

[0077] In some optional embodiments of the present application, the shell comprises two air outlet columns, and the front side of each air outlet column is provided with a first air outlet 13 and a second air outlet 14. The two air outlet columns are a first air outlet column 11 and a second air outlet column 12.

[0078] In the embodiment, by arranging two air outlet columns, the air conditioner indoor unit can have more air outlet modes. For example, one air outlet column can be selected to blow air alone or two air outlet columns can blow air at the same time according to the requirement to increase the air volume. For another example, the air outlet angles of the air outlet columns are different, which can increase the air outlet angle of the air conditioner indoor unit. The two air outlet columns can blow different air, one air outlet column blows heat exchange air and the other air outlet column blows non-heat exchange air (indoor air or outdoor fresh air). According to the requirement of the user or the detection of the indoor environment, one air outlet column or two air outlet columns can be selected to blow air. The multiple air outlet modes can meet the multiple requirements of the user, thereby improving the comfort of the air conditioner indoor unit.

[0079] When the two air outlet columns blow air to the inside, the left and right air zones will interact. In the interaction area, the air volume will be large and the user experience will be poor because the left and right air blow at the same time. In the embodiment, the air outlet of the first air outlet column blows cooling air, and the first air outlet of the second air outlet column blows non-heat exchange air to the first air outlet column, which can realize cool air supply and improve the user experience.

[0080] Further, the second air outlet 14 is located on the side of the first air outlet 13 away from the other air outlet column; the two air outlet columns are arranged at intervals to form the air guide interval 20 between the two air outlet columns; and the first air outlet is provided with an air guide device 17 for horizontal air guide and / or vertical air guide.

[0081] For example, the air guide device 17 includes at least one air guide plate for horizontal air guide. Alternatively, the air guide device 17 includes at least one air guide plate for horizontal air guide and a swing leaf for vertical air guide.

[0082] In some optional embodiments of the present application, the air guide interval 20 only includes an air inlet section and an air outlet section connected to each other. The width of the air outlet section gradually increases along the flow direction of the air flow. The width of the air inlet section gradually decreases along the flow direction of the air flow. The above arrangement of the air guide interval 20 is beneficial to the air entering the rear side of the air guide interval 20 and also beneficial to the air flowing forward in the air guide interval 20.

[0083] In some optional embodiments of the present application, the indoor heat exchanger 18 and the indoor fan 19 are arranged in each air outlet column.

[0084] Specifically, the air conditioner indoor unit includes two indoor heat exchangers arranged in parallel. The two indoor heat exchangers are connected with a flow path control device configured to control the two indoor heat exchangers to work at the same time or only one indoor heat exchanger to work.

[0085] For example, the flow path control device includes two electronic on-off valves, which are respectively connected in series with corresponding indoor heat exchangers. The electronic on-off valves are connected in series with the heat exchangers, and the flow path of the working medium in the heat exchangers is controlled by the electronic on-off valves, so that the action is stable and reliable.

[0086] Further, in some optional embodiments of the present application, the two air outlet columns 10 are symmetrically arranged about a vertical reference plane extending in front and back. The symmetrically arranged air outlet columns 10 make the appearance of the indoor unit of the standing air conditioner stable and accord with the aesthetic sense of Chinese people.

[0087] In some optional embodiments of the present application, the indoor unit is a standing air conditioner indoor unit. In some alternative embodiments, the indoor unit is a wall-mounted air conditioner indoor unit.

[0088] At this point, those skilled in the art should recognize that, although the present application has been fully illustrated and described herein with reference to a plurality of exemplary embodiments, many other variants or modifications in accordance with the principles of the present application can be directly determined or deduced from the disclosure of the present application without departing from the spirit and scope of the present application.
