[0025] When the second air outlet column is at the initial position, the airflow flowing out of the first air outlet and the airflow flowing out of the second air outlet can be mixed.

[0026] The second air outlet column forms an air guide interval with the first air outlet column when at the initial position, so that when air is blown out from the first air outlet and / or the second air outlet, the air in the air guide interval is driven to flow forward by the negative pressure.

[0029] Further, in the air conditioner indoor unit of the present application, the air flow flowing out of the second air outlet is at least formed under the action of the functional module, the air flow flowing out of the second air outlet is blown separately, so that the additional function of the air conditioner indoor unit does not have to depend on the heat exchange air duct. At the same time, the second air outlet column can rotate, which is convenient for the delivery of the air flow flowing out of the second air outlet. For example, when the requirement for the air flow flowing out of the second air outlet is relatively high, the delivery of the air flow flowing out of the second air outlet is accelerated and the second air outlet column is rotated at the same time, so that it can be better diffused to all parts of the room, and the effect of the functional module is improved, such as the effect of humidification, fresh air, dust removal, sterilization, oxygen enrichment, etc.

[0043] Figure 1 is a schematic front view of an air conditioner indoor unit according to an embodiment of the present application, as shown in Figure 1 and referring to Figures 2 to 7 , the embodiment of the present application provides an air conditioner indoor unit, which comprises a first air outlet column 10 and a second air outlet column 20.

[0044] The first air outlet column 10 is in a vertical column shape, and a front side of the first air outlet column 10 is provided with a first air outlet 11 for blowing air flow, and the first air outlet 11 is in a vertical strip shape. The second air outlet column 20 is in a vertical column shape, and a front side of the second air outlet column 20 is provided with a second air outlet 21 for blowing air flow, and the second air outlet 21 is in a vertical strip shape. When the second air outlet column 20 is at an initial position, the first air outlet column 10 is arranged in a transverse direction, and the left-right direction perpendicular to the front-rear direction of the air conditioner indoor unit is the "transverse direction".

[0045] Specifically, the airflow flowing out of the first air outlet 11 is a heat exchange airflow. The "heat exchange airflow" refers to the airflow that has completed heat exchange with the heat exchanger 14 of the air conditioner and is used to adjust the indoor temperature. The heat exchanger 14 is connected to the compressor, the heat exchanger of the outdoor unit, the throttling device and other refrigeration elements through pipelines to form a vapor compression refrigeration cycle system. When the air conditioner indoor unit is in a cooling mode, the heat exchange airflow is cold air. When the air conditioner indoor unit is in a heating mode, the heat exchange airflow is hot air. The heat exchange airflow is blown to the indoor environment through the first air outlet 11 to complete the cooling and heating of the indoor environment. The airflow flowing out of the second air outlet 21 is a non-heat exchange airflow, which is used to assist in adjusting the indoor environment. When the air conditioner indoor unit of the embodiment of the present application is running, the first air outlet column 10 and the second air outlet column 20 can be opened alternately or simultaneously to send air.

[0046] In this embodiment of the present application, in particular, the second air outlet column 20 is movably arranged, and the second air outlet column 20 is rotatably arranged around a vertical axis. For example, the second air outlet column 20 can be moved and rotated by a driving device. The driving device is configured to at least drive the second air outlet column to move from an initial position to a preset position and to rotate the second air outlet column around the vertical axis, so that the second air outlet is aligned with the first air outlet when the second air outlet is at the preset position, thereby causing the airflow flowing out of the first air outlet 11 to enter the second air outlet column 20 through the second air outlet 21, or causing the airflow flowing out of the second air outlet 21 to enter the first air outlet column 10 through the first air outlet 11, as shown in Figure 3 .

[0047] By arranging the driving device, the second air outlet can be aligned with the first air outlet, thereby causing the non-heat exchange airflow to enter the first air outlet 11 to remove dust from the filter screen arranged at the first air inlet 13, and also causing the non-heat exchange airflow to remove condensation at the first air outlet 11, so that the air conditioner indoor unit has multiple functions and improves the practicality of the air conditioner indoor unit. No special equipment is needed for dust removal, which is low in cost and energy-saving. In some alternative embodiments of the present application, the second air outlet column 20 can also be at other positions when it is at the initial position, such as the position shown in Figure 4 .

[0048] Further, in some embodiments of the present application, the second air outlet column 20 can have at least three positions to meet different air supply requirements. For example, the driving device includes a track 50 and a slider arranged on the track 50, and the second air outlet column 20 is rotatably mounted on the slider. The second air outlet column 20 can be stopped at any position on the track, such as the position shown in Figures 3 to 7 , and can also be rotated.

[0049] In some embodiments of the present application, the track 50 comprises a first track segment 51 and a second track segment 52. The first track segment 51 extends along the transverse direction and is arranged at the front side of the first air outlet column 10. The second track segment 52 is connected at one end of the first track segment 51 near the second air outlet column 20, and extends from the front end thereof to the rear end thereof in a rearward and outward direction away from the first air outlet column 10; the preset position is the connection between the first track segment 51 and the second track segment 52. In some alternative embodiments of the present application, the two ends of the track are connected to form a circle around the first air outlet column 10, such as a circle coaxial with the rotation axis of the heat exchange fan.

[0050] In the embodiments of the present application, the second air outlet column 20 has at least two relative positions with respect to the first air outlet column 10. For example, the second air outlet column 20 also has a position in the flow-out direction of the airflow flowing out of the first air outlet 11 to shield the first air outlet 11 and prevent the first air outlet 11 from directly blowing. Also for example, the second air outlet column 20 also has a position between the first air outlet 11 and the user position to shield the first air outlet 11 and prevent the airflow blown out of the first air outlet 11 from directly blowing the person at the user position, and further the user position can be detected by human sensing, and then the second air outlet column 20 is controlled to move to between the user position and the first air outlet 11. For another example, the second air outlet 21 can be rotated to a position aligned with the first air inlet 13, or the second air inlet 23 can be rotated to a position aligned with the first air outlet 11.

[0051] In some embodiments of the present application, when the second air outlet column is at the initial position, the first air outlet 11 faces forward and toward the second air outlet column 20, i.e., the first air outlet 11 faces obliquely forward, and the second air outlet 21 faces forward and toward the first air outlet column 10, i.e., the second air outlet 21 faces obliquely forward. Further, the rear side edge of the second air outlet 21 is at the front side of the rear side edge of the first air outlet 11; the front side edge of the second air outlet 21 is at the rear side of the front side edge of the first air outlet 11. The front side of the first air outlet column 10 is provided with a display device 18, and the display device 18 is at the side of the first air outlet 11 away from the second air outlet 21.

[0052] In some embodiments of the present application, the first air outlet column 10 is provided with a first air guide for guiding the transverse air outlet direction of the first air outlet 11. The first air guide can comprise a plurality of first air guide plates 12. "Guiding the transverse air outlet direction" refers to changing the included angle between the air outlet direction and the front-rear direction, such as making the airflow blow toward the front, toward the left front, toward the right front, and the like. The second air outlet column 20 is provided with a second air guide for guiding the transverse air outlet direction of the second air outlet 21. The second air guide can comprise a plurality of second air guide plates 22. The main control board of the air conditioner can be electrically connected to the motors of the first air guide and the second air guide at the same time, so as to control the two to act in coordination.

[0053] In particular, when the second air outlet is aligned with the first air outlet, the first air deflector is perpendicular to the plane where the first air outlet is located, and the first air deflector and the second air deflector can be parallel, guiding the airflow flowing out of the first air outlet 11 to the second air outlet 21 or guiding the airflow flowing out of the second air outlet 21 to the first air outlet 11.

[0054] In some embodiments of the present application, the number of the first air deflectors 12 is at least two, and the rotation axis of the last side first air deflector 12 is located at the rear side edge of the first air outlet, or the distance between the rotation axis of the last side first air deflector 12 and the rear side edge of the first air outlet is less than the distance between the rotation axis of the last side first air deflector 12 and the front side edge of the first air outlet. The rotation axis of the last side second air deflector 22 is located at the rear side edge of the second air outlet, or the distance between the rotation axis of the last side second air deflector 22 and the rear side edge of the second air outlet is less than the distance between the rotation axis of the last side second air deflector 22 and the front side edge of the second air outlet; the number of the second air deflectors 22 is one. Preferably, the number of the first air deflectors 12 is two. The number of the second air deflectors 22 is one.

[0055] In some embodiments of the present application, the lower end or the upper end of the second air outlet column 20 is rotatably arranged around a horizontal axis perpendicular to the plane where the first air outlet 11 is located, so that the second air outlet column 20 can be rotated to the front of the first air outlet to block part of the area of the first air outlet. By arranging the second air outlet column 20 obliquely, part of the area of the first air outlet 11 can be blocked, such as the area with the highest outlet temperature, the area with the lowest outlet temperature, etc., so that the outlet temperature of the first air outlet 11 is more uniform, improving the comfort of the user. Of course, it can also be blocked according to the needs of the user to improve the user experience.

[0056] Further, the air conditioner indoor unit further comprises a plurality of temperature sensors arranged in sequence along the vertical direction at the first air outlet 11 to detect the outlet temperature of the first air outlet 11 at a plurality of parts along the up and down directions, and then rotate the second air outlet column 20 to the front side of the area of the first air outlet 11 corresponding to the corresponding outlet temperature according to the outlet temperature. Specifically, the first air outlet 11 is divided into six areas, and the outlet temperature of the six areas is detected by six temperature sensors respectively. When heating, the second air outlet column 20 is rotated to the front side of the area of the first air outlet 11 corresponding to the lowest outlet temperature; when cooling, the second air outlet column 20 is rotated to the front side of the area of the first air outlet 11 corresponding to the highest outlet temperature.

[0057] In some embodiments of the present application, as shown in Figure 1As shown, at the initial position of the second air outlet column, the air flow out of the first air outlet 11 and the air flow out of the second air outlet 21 can be mixed. The air flow out of the second air outlet 21 can be a non-heat exchange air flow, and the air flow out of the first air outlet 11 and the air flow out of the second air outlet 21 can be mixed after being blown out, forming a mixed air flow. The temperature of the mixed air flow is closer to the room temperature than the heat exchange air flow, and the comfort is higher. The air feeling is more soft, and the air volume and air speed are increased, the air supply distance is farther, and the air flow out of the second air outlet 21 can be better diffused to all parts of the room.

[0058] In some embodiments of the present application, as shown in Figure 1 As shown, at the initial position of the second air outlet column, the air flow out of the first air outlet 11 and the air flow out of the second air outlet 21 can be mixed. The air flow out of the second air outlet 21 can be a non-heat exchange air flow, and the air flow out of the first air outlet 11 and the air flow out of the second air outlet 21 can be mixed after being blown out, forming a mixed air flow. The temperature of the mixed air flow is closer to the room temperature than the heat exchange air flow, and the comfort is higher. The air feeling is more soft, and the air volume and air speed are increased, the air supply distance is farther, and the air flow out of the second air outlet 21 can be better diffused to all parts of the room.

[0059] In some embodiments of the present application, as shown in Figure 1 As shown, the first air outlet 11 and the second air outlet 21 can be a whole vertical bar extending from top to bottom, or can be composed of a plurality of sub-air outlets arranged vertically in an intermittent vertical bar.

[0060] In some embodiments of the present application, since the second air outlet column 20 does not need to be provided with a heat exchanger 14, the second air outlet column 20 can be designed to be thinner, and it is obviously thinner than the first air outlet column 10. This asymmetric design not only meets the air outlet needs, but also makes the appearance of the air conditioner indoor unit more novel and unique, and improves the competitiveness of the product.

[0061] For example, as shown in Figures 1 to 4As shown, the ratio of the width of the second air outlet column 20 in the lateral direction to the width of the first air outlet column 10 in the lateral direction can be less than 1 / 2. The ratio of the depth of the second air outlet column 20 in the front-rear direction to the depth of the first air outlet column 10 in the front-rear direction can be less than 1 / 2, so as to form a double-column differentiated appearance. When the second air outlet column is in the initial position, the front-rear positions of the second air outlet 21 and the first air outlet 11 can be flush or substantially flush, for example, the front-rear distance between the two is not more than 10 cm, so that the non-heat exchange airflow and the heat exchange airflow are better mixed. That is, the second air outlet column 20 is mainly located on one side of the first air outlet column 10 in the lateral direction; or, the second air outlet column 20 is mostly or entirely located on one side of the first air outlet column 10 in the lateral direction.

[0062] In some embodiments of the present application, as shown in Figure 2 The rear side of the first air outlet column 10 is provided with a first air inlet 13 communicating with the first air outlet 11. The first air outlet column 10 is provided with a heat exchanger 14 and a heat exchange fan 15. The heat exchange fan 15 causes the heat exchange airflow after the heat exchanger 14 to flow out of the first air outlet 11. At this time, the airflow flowing out of the first air outlet 11 is a heat exchange airflow. The heat exchange fan is preferably a cross-flow fan. In some alternative embodiments, the heat exchange fan 15 can be a plurality of axial flow fans or centrifugal fans arranged in sequence in the up-down direction.

[0063] In some embodiments of the present application, as shown in Figure 2 The rear side of the second air outlet column 20 is provided with a second air inlet 23 communicating with the second air outlet 21. The second air outlet column 20 is provided with a vertical strip-shaped air duct, which communicates with the second air inlet 23 and the second air outlet 21. The air duct is provided with a first fan 31. The first fan 31 causes the airflow to enter the air duct from the second air inlet 23 and then flow out of the first air outlet 11. The first fan 31 is a cross-flow fan. By providing a driving device, the airflow flowing out of the first air outlet 11 can enter the second air outlet 21, and the filter screen provided at the second air inlet 23 can be dusted. The air conditioner indoor unit has multiple functions and improves the practicality of the air conditioner indoor unit.

[0064] In some embodiments of the present application, the air conditioner indoor unit further comprises a functional module 40. The functional module 40 is configured to process the gas flowing therethrough or add substances to the airflow. The functional module 40 cooperates with the second air outlet column 20. The outlet of the functional module 40 communicates with the upper end or the lower end of the air duct; or, the outlet of the functional module 40 communicates with the second air inlet 23.

[0065] The functional module 40 is one or more of a fresh air device, an oxygen adding device, a purifying device, a humidifying device, and a water washing device. When the outlet of the functional module 40 is communicated with the second air inlet 23, the corresponding non-heat exchange air flow is one or more of a fresh air flow, a purifying air flow, a humidifying air flow, an oxygen adding air flow, and a water washing air flow. When the outlet of the functional module 40 is communicated with the upper end or the lower end of the air duct, the corresponding non-heat exchange air flow is one or more of a mixed air flow formed by the fresh air flow, the purifying air flow, the humidifying air flow, the oxygen adding air flow, and the water washing air flow and the indoor air, that is, the second air outlet 21 is simultaneously communicated with one indoor air inlet and the outlet of the functional module 40, and the indoor air of the indoor air inlet is mixed with the substance or gas from the functional module 40. Further, the purifying device has a dust removing and / or sterilizing function, that is, the purifying device is a dust removing device, a sterilizing device, or a device having both dust removing and sterilizing functions. Of course, the functional module 40 can also adopt other functional modules 40 capable of changing the air quality.

[0066] In some embodiments of the present application, the driving device is further configured to rotate the second air outlet column around a vertical axis at the initial position. Preferably, the vertical axis passes through the second air outlet column 20, and the vertical axis is spaced apart from the second air outlet 21, and of course the vertical axis can also be at other positions. Preferably, the vertical axis is the axis of the first fan 31, and such arrangement can only rotate the second air outlet column 20, and the cross-flow fan does not need to follow the rotation, which is simple in structure and convenient to control and easy to implement.

[0067] When the air conditioner indoor unit of the embodiments of the present application operates, the first air outlet column 10 and the second air outlet column 20 can be opened to blow air alternatively or simultaneously. The second air outlet column 20 can be rotated to a preset position to blow air according to requirements, or the second air outlet column 20 can be rotated at all times when blowing air, which can be clockwise rotation or counterclockwise rotation.

[0068] Specifically, in this embodiment, the air flow flowing out of the second air outlet 21 is formed at least under the action of the functional module 40, and the second air outlet column 20 can be rotated to facilitate the delivery of the air flow flowing out of the second air outlet 21. For example, when the requirement for the air flow flowing out of the second air outlet 21 is relatively high, the delivery of the air flow flowing out of the second air outlet 21 is accelerated and the second air outlet column 20 is rotated at the same time, so that it can better diffuse to all parts of the room, and the effect of the functional module 40 is improved, such as the humidifying / fresh air / dust removing / sterilizing / oxygen adding effect. Specifically, the driving device is started when the flow rate of the air flow flowing out of the second air outlet 21 reaches a preset value.

[0069] Further, in some embodiments of the present application, the second air outlet column 20 can also be rotated around a vertical axis when it is necessary to change the air mixing effect. In this way, the air outlet direction of the air flow out of the second air outlet 21 can be changed, and the air induction amount can be changed to obtain different air outlet effects and more air outlet forms, to meet the individual needs of users and improve the user experience. Preferably, when the air flow out of the second air outlet 21 is a mixed air flow formed by one or more of the fresh air flow, the purified air flow, the humidified air flow, the oxygenated air flow, and the water-washed air flow and the indoor air, i.e., when the second air outlet column 20 also blows indoor air, a stronger air mixing effect can be achieved, and the air flow is closer to room temperature.

[0070] In some embodiments of the present application, the functional module 40 includes an air inlet and a second fan that induces air into the air inlet and then out of the outlet of the functional module 40. For example, the functional module 40 is a fresh air module, etc. At this time, the air conditioner indoor unit can include the first fan 31, the second fan, the second air inlet 23, and the air inlet. The air inlet can be in communication with the second air inlet 23, so that the non-heat exchange air flow is one or more of the fresh air flow, the purified air flow, the humidified air flow, the oxygenated air flow, and the water-washed air flow; or the air inlet and the second air inlet 23 are not in communication, and the corresponding non-heat exchange air flow is a mixed air flow formed by one or more of the fresh air flow, the purified air flow, the humidified air flow, the oxygenated air flow, and the water-washed air flow and the indoor air. Further, the substance from the functional module 40 can be located on one side or the other side of the first fan 31 facing the second air outlet 21.

[0071] In some alternative embodiments of the present application, when the air inlet is in communication with the second air inlet 23, only one of the first fan 31 and the second fan needs to be selected. In other alternative embodiments of the present application, when the air inlet is in communication with the lower end or the upper end of the air duct and does not have the second air inlet 23, only the second fan needs to be included.

[0072] In some embodiments of the present application, the functional module 40 includes only an outlet, for example, the functional module 40 is a humidifying device, an oxygenating device, etc., and the substance from the functional module 40 can be located on one side or the other side of the first fan 31 facing the second air outlet 21, to mix with the indoor air from the second air inlet 23.

[0073] In some embodiments of the present application, as Figure 1As shown, the air conditioner indoor unit further comprises a lower shell 30, the first air outlet column 10 and the second air outlet column 20 are arranged at the top end of the lower shell 30, the functional module 40 is arranged in the lower shell 30, and the second fan is an axial fan or a centrifugal fan. The first air outlet column 10 and the second air outlet column 20 are arranged at the top end of the lower shell 30, the lower shell 30 has a supporting effect and also provides a mounting space for the functional module 40, the lower shell 30 is provided with a fresh air inlet and at least one indoor air inlet, and the two are selectively or simultaneously communicated with the air inlet of the second fan. The fresh air inlet is connected with a fresh air pipe to introduce fresh air flow from the outside.

[0074] In some embodiments of the present application, the functional module 40 is a humidifying device which supplies water mist to the lower end of the air duct, the water mist is mixed into the air flow entering from the second air inlet, and the mixed air flow is blown out from the second air outlet 21. The air conditioner indoor unit can have the following working modes: when the indoor humidity is less than a first preset humidity, neither the functional module 40 nor the first fan 31 works; when the indoor humidity is less than a second preset humidity and greater than the first preset humidity, the functional module 40 works and the first fan 31 works at a low speed; when the indoor humidity is less than a third preset humidity and greater than the second preset humidity, the functional module 40 works and the first fan 31 works at a high speed; and when the indoor humidity is greater than the third preset humidity, the functional module 40 works and the first fan 31 works at a high speed, and the second air outlet column 20 rotates clockwise or counterclockwise to blow water vapor to the surroundings in a rotating manner to improve the humidifying effect. The second air outlet column 20 can continuously rotate in the counterclockwise direction or in the clockwise direction. The first preset humidity is less than the second preset humidity, and the second preset humidity is less than the third preset humidity. In some other embodiments of the present application, the second air outlet column 20 can be rotated to a position and then kept at the position to work for a period of time.

[0075] Further, when the functional module 40 is of other types, similar modes as described above can also be adopted. Further, the fresh air device can be controlled according to the concentration of indoor carbon dioxide, the dust removal device can be controlled according to the concentration of indoor PM2.5, the sterilization device can be controlled according to the concentration of indoor bacteria, and the oxygen adding device can be controlled according to the oxygen concentration.
