The person skilled in the art should be able to understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0042] The present application provides an air conditioner indoor unit. The air conditioner indoor unit is the indoor part of a split air conditioner, used to adjust indoor air, such as refrigeration / heat, dehumidification, introduction of fresh air, etc. The air conditioner indoor unit can be a floor-standing cabinet machine, or a vertical wall-mounted machine.

[0043] Figure 1 The air conditioner indoor unit of an embodiment of the present application is shown in the schematic front view as shown in Figure 1 , and with reference to Figures 2 to 6 , the present application provides an air conditioner indoor unit, which comprises a first air outlet column 10, a second air outlet column 20 and a water absorption structure 50.

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

[0045] Specifically, the air flow flowing out of the first air outlet 11 is heat exchange air flow. The "heat exchange air flow" refers to the air flow 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 with 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 cooling mode, the heat exchange air flow is cold air. When the air conditioner indoor unit is in heating mode, the heat exchange air flow is hot air. The heat exchange air flow blows towards the indoor environment through the first air outlet 11 to complete cooling and heating of the indoor environment. The air flow flowing out of the second air outlet 21 is non-heat exchange air flow, which is used to assist in adjusting the indoor environment. The air conditioner indoor unit of the present application can make the first air outlet column 10 and the second air outlet column 20 open air supply alternatively or simultaneously.

[0046] In this embodiment of the invention, since there is no need to install a heat exchanger 14 inside the second air outlet column 20, the second air outlet column 20 can be designed to be thinner, making it significantly thinner than the first air outlet column 10. This asymmetrical design not only meets the air outlet requirements, but also makes the appearance of the air conditioner indoor unit more novel and unique, thereby enhancing the product's competitiveness.

[0047] For example, such as Figures 1 to 6 As 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-to-back direction to the depth of the first air outlet column 10 in the front-to-back direction can also be less than 1 / 2, to create a differentiated appearance between the two columns. The front-to-back positions of the second air outlet 21 and the first air outlet 11 can be aligned or substantially aligned, for example, the front-to-back distance between them can not exceed 10cm, so that the non-heat exchange airflow and the heat exchange airflow can be better mixed. That is to say, the second air outlet column 20 is mainly located on one side of the front half of the first air outlet column 10 in the lateral direction; or, in other words, most or all of the second air outlet column 20 is located on one side of the front half of the first air outlet column 10 in the lateral direction.

[0048] The second air outlet column 20 is rotatably arranged around a vertical axis. A water-absorbing structure is provided on the peripheral wall of the second air outlet column 20 so as to wipe a portion of the peripheral wall of the first air outlet column 10 during the rotation of the second air outlet column 20, thereby absorbing the moisture on that portion of the wall; this portion of the wall is connected to the first air outlet 11 and faces the second air outlet column 20.

[0049] Since the second air outlet column 20 is located on the lateral side of the front half of the first air outlet column 10, a water absorption structure 50 is set on the peripheral wall of the second air outlet column. The water absorption structure 50 can rotate around the vertical axis with the second air outlet column 20, and at the same time wipe the condensation at the first air outlet 11, so that the function of the air conditioner indoor unit is no longer single, but has multiple functions, thus improving the practicality of the air conditioner indoor unit.

[0050] In some embodiments of the present invention, the first air outlet 11 faces forward and towards the second air outlet column 20, that is, the first air outlet 11 faces diagonally forward, and the second air outlet 21 faces forward and towards the first air outlet column 10, that is, the second air outlet 21 faces diagonally forward. Further, the rear edge of the second air outlet 21 is located in front of the rear edge of the first air outlet 11; the front edge of the second air outlet 21 is located behind the front edge of the first air outlet 11. A display device 18 is provided on the front side of the first air outlet column 10, and the display device 18 is located on the side of the first air outlet 11 opposite to the second air outlet 21.

[0051] In some embodiments of the present application, the first air outlet column 10 is provided with a first air guide for guiding the lateral air outlet direction of the first air outlet 11. The first air guide can include a plurality of first air guide plates 12. "Guiding the lateral air outlet direction" refers to changing the included angle between the air outlet direction and the front-rear direction, such as making the air flow blow towards the front, towards the left front, towards the right front, and the like. The second air outlet column 20 is provided with a second air guide for guiding the lateral air outlet direction of the second air outlet 21. The second air guide can include 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 first air guide at the same time, so as to control the coordinated action of the two.

[0052] In some embodiments of the present application, the number of first air guide plates 12 is at least two, the rotation axis of the last side first air guide plate 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 guide plate 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 guide plate 12 and the front side edge of the first air outlet. The rotation axis of the last side second air guide plate 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 guide plate 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 guide plate 22 and the front side edge of the second air outlet; the number of second air guide plates 22 is one. Preferably, the number of first air guide plates 12 is two. The number of second air guide plates 22 is one.

[0053] In some embodiments of the present application, the water absorption structure wipes part or all of the outer surface of one or more first air guide plates 12 during the rotation of the second air outlet column 20 around the vertical axis, thereby cleaning the first air guide plates 12. It can be seen that the water absorption structure has the dual functions of wiping condensation and wiping dust, thereby improving the cleanliness of the appearance of the equipment.

[0054] In some embodiments of the present application, the water absorption structure 50 is a vertically arranged water absorption sheet, and the water absorption structure is made of a flexible material. Specifically, during the rotation of the second air outlet column 20, the water absorption sheet wipes the first air outlet 11 and the first air guide plate 12. When the water absorption sheet contacts the above-mentioned partial area, the first air guide plate 12 or the first air outlet 11, the water absorption sheet can be bent; after the water absorption sheet is separated from the above-mentioned partial area, the first air guide plate 12 or the first air outlet 11, the water absorption sheet can automatically reset. The water absorption sheet can include a flexible base body and a cotton / nylon / gauze or other water absorption material arranged on the flexible base body.

[0055] In some embodiments of the present application, the water absorption structure 50 is arranged on the side of the rear part of the second air outlet column 20 facing the first air outlet column 10; the water absorption structure 50 is mounted on the second air outlet column 20 through an opening structure configured to make the water absorption structure 50 contact the rear surface of the second air outlet column 20 and open the water absorption structure at a preset angle relative to the second air outlet column; the rear surface of the second air outlet column 20 is provided with a second air inlet communicating with the second air outlet 21. Specifically, the transverse dimension of the water absorption structure can be set according to actual needs, as long as the water absorption structure can contact the first air outlet and the first air deflector 12 during the rotation of the second air outlet column.

[0056] In operation, it is determined whether the condensation area (the condensation area refers to the area around the first air outlet 11 and the outer surface of the first air deflector 12, i.e. the part of the above-mentioned circumferential wall and the outer surface of the first air deflector 12) needs to be dehumidified; when the condensation area needs to be dehumidified, the water absorption structure 50 is rotated with the second air outlet column 20 around the vertical axis to the first air outlet 11 to wipe off the condensation. Specifically, by determining whether the condensation area needs to be dehumidified through the ambient temperature, the ambient humidity and the condensation area temperature, when the condensation area needs to be dehumidified, the first air deflector 12 is rotated to the rightmost position, i.e. the first air deflector 12 is closed to facilitate wiping off the condensation, and the water absorption structure is opened at a preset angle relative to the second air outlet column, and the second air outlet column 20 is rotated clockwise around the vertical axis for one revolution, so that the condensation can be wiped off completely. After wiping off the condensation, the first air deflector 12 returns to the set position, and the calculation of whether the condensation area needs to be dehumidified is restarted.

[0057] 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 in 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 air outlet temperature, the area with the lowest air outlet temperature, etc., so that the air outlet temperature of the first air outlet 11 is more uniform, improving the comfort of the user. Of course, the blocking can also be performed according to the needs of the user to improve the user experience.

[0058] 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 air outlet temperature at a plurality of positions along the up-down direction of the first air outlet 11, and then the second air outlet column 20 is rotated to the front side of the region of the first air outlet 11 corresponding to the air outlet temperature. Specifically, the first air outlet 11 is divided into six regions, and the air outlet temperature of the six regions is detected by six temperature sensors respectively. In heating, the second air outlet column 20 is rotated to the front side of the region of the first air outlet 11 corresponding to the lowest air outlet temperature; in cooling, the second air outlet column 20 is rotated to the front side of the region of the first air outlet 11 corresponding to the highest air outlet temperature.

[0059] In some embodiments of the present application, as shown in Figure 1 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 to form a mixed air flow. The temperature of the mixed air flow is closer to room temperature than that of the heat exchange air flow, and the comfort is higher. The air flow is more soft, and the air volume and air speed are increased, and the air supply distance is farther.

[0060] In some embodiments of the present application, as shown in Figure 1 The second air outlet column 20 and the first air outlet column 10 form an air guiding interval 16 therebetween, so that when the first air outlet 11 and / or the second air outlet 21 blows air, the air in the air guiding interval 16 is driven to flow forward by the negative pressure. The first air outlet column 10 and the second air outlet column 20 form the air guiding interval 16 therebetween. In this way, when the first air outlet column 10 and / or the second air outlet column 20 blows air, a negative pressure environment is formed at the air guiding interval 16, which promotes the indoor air at the rear of the air conditioner indoor unit to flow forward through the air guiding interval 16 to mix into the air flow of the first air outlet column 10 or the second air outlet column 20. This makes the mixing amount of indoor air larger and the mixing speed faster, and forms a stronger air mixing effect. The temperature of the mixed air flow is closer to room temperature than that of the heat exchange air flow, and the comfort is higher. The air flow is more soft, and the air volume and air speed are increased, and the air supply distance is farther.

[0061] In some embodiments of the present application, as shown in Figure 1 The first air outlet 11 and the second air outlet 21 can be an integral 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.

[0062] In some embodiments of the present application, as shown in Figure 2As shown, the rear side of the first air outlet column 10 is provided with a first air inlet 13 which is in communication with the first air outlet 11. The first air outlet column 10 is provided with a heat exchanger 14 and a heat exchanger fan 15. The heat exchanger 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 exchanger fan is preferably a cross-flow fan. In some alternative embodiments, the heat exchanger 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 As shown, the rear side of the second air outlet column 20 is provided with a second air inlet 23 which is in communication with the second air outlet 21. The second air outlet column 20 is provided with a vertical strip-shaped air duct which is in communication 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.

[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 is in communication with the upper end or the lower end of the air duct; or, the outlet of the functional module 40 is in communication 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 purification device, a humidification device, and a water washing device. When the outlet of the functional module 40 is in communication with the second air inlet 23, the corresponding non-heat exchange airflow is one or more of a fresh air flow, a purification airflow, a humidification airflow, an oxygen adding airflow, and a water washing airflow. When the outlet of the functional module 40 is in communication with the upper end or the lower end of the air duct, the corresponding non-heat exchange airflow is a mixed airflow formed by one or more of a fresh air flow, a purification airflow, a humidification airflow, an oxygen adding airflow, and a water washing airflow and indoor air, that is, the second air outlet 21 simultaneously communicates with an indoor air inlet and the outlet of the functional module 40, and the indoor air of the indoor air inlet is mixed with the substances or gas from the functional module 40. Further, the purification device has a dust removal and / or sterilization function, that is, the purification device is a dust removal device, a sterilization device, or a device having both dust removal and sterilization functions. Of course, the functional module 40 can also adopt other functional modules 40 capable of changing air quality.

[0066] In some embodiments of the present application, the vertical axis passes through the second air outlet column 20, and the vertical axis is spaced apart from the second air outlet 21. Of course, the vertical axis can also be at other positions. Preferably, the vertical axis is the axis of the first fan 31. In this way, only the second air outlet column 20 needs to be rotated, and the cross-flow fan does not need to follow the rotation, which is simple in structure and convenient to control, and is easy to implement. Further, the air conditioner indoor unit further comprises a rotating disc, which is located on the lower side of the second air outlet column 20; the rotating disc is rotatably arranged about the vertical axis, and the lower end of the second air outlet column 20 is rotatably arranged on the rotating disc about a horizontal axis.

[0067] When the air conditioner indoor unit of the embodiments of the present application is in operation, 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. Specifically, in this embodiment, the airflow 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, which facilitates the delivery of the airflow flowing out of the second air outlet 21. For example, when the requirement for the airflow flowing out of the second air outlet 21 is relatively high, the delivery of the airflow flowing out of the second air outlet 21 can be accelerated and the second air outlet column 20 can be rotated at the same time, so that the airflow is better diffused to various parts of the room, and the effect of the functional module 40 is improved, such as the effect of humidification, fresh air, dust removal, sterilization, oxygen addition, etc.

[0068] Further, as shown in Figure 1 the air conditioner indoor unit further comprises a driving device 42 configured to drive the second air outlet column 20 to rotate. The driving device 42 drives the second air outlet column 20 to rotate and deliver the airflow flowing out of the second air outlet 21; the driving device 42 is started when the flow rate of the airflow flowing out of the second air outlet 21 reaches a preset value.

[0069] Further, in some embodiments of the present application, when it is necessary to change the air mixing effect, the second air outlet column 20 can also be rotated about the vertical axis. In this way, the air outlet direction of the airflow flowing out of the second air outlet 21 can be changed, and the amount of air drawn can be changed, so that different air outlet effects and more air outlet forms can be obtained, the individual needs of users can be met, and the user experience can be improved. Preferably, when the airflow flowing out of the second air outlet 21 is a mixed airflow of one or more of fresh air, purified air, humidified air, oxygenated air, and water-washed air and 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 airflow is closer to room temperature.

[0070] In some embodiments of the present application, the functional module 40 comprises an air inlet and a second fan, the second fan causing air to enter the air inlet and then flow out of the outlet of the functional module 40. For example, the functional module 40 is a fresh air module or the like. In this case, the air conditioner indoor unit can comprise 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 fresh air flow, purified air flow, humidified air flow, oxygenated air flow and water-washed air flow; or the air inlet and the second air inlet correspond to a mixed air flow formed by one or more of fresh air flow, purified air flow, humidified air flow, oxygenated air flow and water-washed air flow and 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 is needed. In some 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 is needed.

[0072] In some embodiments of the present application, the functional module 40 comprises only an outlet, for example, the functional module 40 is a humidifying device, an oxygenating device or the like, 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 indoor air from the second air inlet 23.

[0073] In some embodiments of the present application, as shown in Figure 1 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, which serves as a support and 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, which are in communication with the air inlet of the second fan alternatively or simultaneously. The fresh air inlet is connected to 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 delivers water mist to the lower end of the air duct, the water mist mixes 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 air 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 air 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 air fan 31 works at a high speed. When the indoor humidity is greater than the third preset humidity, the functional module 40 works and the first air 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, improving the humidifying effect. The second air outlet column 20 can rotate continuously 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 certain position and then kept working at the position for a period of time. 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 oxygenation device can be controlled according to the oxygen concentration.

[0075] In some embodiments of the present application, the second air outlet column 20 is movably arranged along a preset track around the circumference of the first air outlet column 10, so that the second air outlet column 20 has at least two relative positions relative to the first air outlet column 10. For example, the second air outlet column 20 has an initial position, and the second air outlet column 20 also has a second position in the flow-out direction of the air flow 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. For another example, the second air outlet column 20 has an initial position, and the second air outlet column 20 also has a third position between the first air outlet 11 and the user position, to shield the first air outlet 11 and prevent the air flow blown out of the first air outlet 11 from directly blowing on the person at the user position. Further, the user position can be detected by human sensing, and then the second air outlet column 20 is controlled to move between the user position and the first air outlet 11.

[0076] In some embodiments of the present application, the second air outlet column 20 has an initial position, and the second air outlet column 20 further has a fourth position at which the second air outlet 21 can be rotated to a position aligned with the first air inlet 13, or the second air outlet column 20 further has a fifth position at which the second air inlet 23 can be rotated to a position aligned with the first air outlet 11. Further, the second air outlet column 20 further has a sixth position at which the second air outlet 21 can be rotated to a position aligned with the first air outlet, and dust on the dustproof screen at the first air inlet can be removed when the second air outlet is blowing air, and water in the first air outlet column can also be blown out; dust on the dustproof screen at the second air inlet can be removed when the first air outlet is blowing air,

[0077] Further, the second air outlet column 20 can be moved to the above-mentioned initial position, second position, third position, fourth position, fifth position, and sixth position, and of course can also move to other positions outside the six positions to achieve diversified air supply. Further, the connecting line of the two ends of the preset track is coaxial with the two diagonal connecting lines of the first air outlet column 10; or, the two ends of the preset 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.
