[0045] This invention provides an indoor air conditioning unit, which is the indoor section of a split-type air conditioner, used to regulate indoor air, such as cooling / heating, dehumidifying, and introducing fresh air. The indoor air conditioning unit can be a floor-standing unit, a floor-standing unit, or a wall-mounted unit.

[0046] Figure 1 This is a schematic front view of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and refer to Figures 2 to 5 This invention provides an indoor air conditioning unit, which includes a first air outlet column 10 and a second air outlet column 20.

[0047] The first air outlet column 10 is a vertical column, and a first air outlet 11 for blowing out a first airflow is opened on the front side of the first air outlet column 10. The first air outlet 11 is vertical. The second air outlet column 20 is a vertical column, and a second air outlet 21 for blowing out a second airflow is opened on the front side of the second air outlet column 20. The second air outlet 21 is vertical. The second air outlet column 20 and the first air outlet column 10 are arranged horizontally. The left-right direction, which is perpendicular to the front-back direction of the indoor unit of the air conditioner, is called "horizontal".

[0048] Specifically, the first airflow is a heat exchange airflow. "Heat exchange airflow" refers to the airflow that exchanges heat with the air conditioner's heat exchanger 14 to regulate the indoor temperature. The heat exchanger 14, along with the compressor, the outdoor unit's heat exchanger, the throttling device, and other refrigeration components, are connected via pipes to form a vapor compression refrigeration cycle system. When the indoor unit is in cooling mode, the heat exchange airflow is cold air. When the indoor unit is in heating mode, the heat exchange airflow is hot air. The heat exchange airflow is blown into the indoor environment through the first air outlet 11, completing the cooling and heating of the indoor environment. The second airflow is a non-heat exchange airflow, whose function is to provide auxiliary regulation of the indoor environment.

[0049] When the indoor unit of the air conditioner in this embodiment of the invention is running, the first air outlet column 10 and the second air outlet column 20 can be turned on one or both simultaneously to supply air. Alternatively, the first air outlet column 10 and the second air outlet column 20 can be turned on simultaneously. In this embodiment of the invention, the indoor unit of the air conditioner uses the first air outlet column 10 to blow out a first airflow, which can be a heat exchange airflow, and uses the second air outlet column 20 to blow out a second airflow. The first and second airflows are blown out independently, so that the additional functions of the indoor unit of the air conditioner do not necessarily depend on the heat exchange air duct.

[0050] In this embodiment of the invention, the first air outlet 11 faces forward and towards the second air outlet column 20, i.e., the first air outlet 11 faces diagonally forward, and the second air outlet 21 faces forward and towards the first air outlet column 10, i.e., the second air outlet 21 faces diagonally forward. 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 away from the second air outlet 21. Furthermore, the lower end or upper end of the second air outlet column 20 is rotatably arranged about a horizontal axis, which is perpendicular to the plane where the first air outlet 11 is located, so that the second air outlet column 20 can rotate to the front of the first air outlet and block a part of the area of ​​the first air outlet.

[0051] By tilting the second air outlet column 20, it can block part of the first air outlet 11, such as the area with the highest or lowest air temperature, making the air temperature of the first air outlet 11 more uniform and improving the user's comfort. Of course, it can also be blocked according to the user's needs to enhance the user experience.

[0052] like Figures 3 to 5 As shown, the indoor unit of the air conditioner also includes multiple temperature sensors, which are arranged vertically at the first air outlet 11 to detect the air outlet temperature at multiple points along the top and bottom of the first air outlet 11. Based on the air outlet temperature, the second air outlet column 20 rotates to the front of the area corresponding to the corresponding air outlet temperature on the first air outlet 11. Specifically, the first air outlet 11 is divided into six areas: A, B, C, D, E, and F. Six temperature sensors detect the air outlet temperature in each of these six areas. During heating, the second air outlet column 20 rotates to the front of the area corresponding to the lowest air outlet temperature on the first air outlet 11; during cooling, the second air outlet column 20 rotates to the front of the area corresponding to the highest air outlet temperature on the first air outlet 11.

[0053] In some embodiments of the present invention, such as Figure 1 As shown, at the initial position, the first airflow from the first air outlet 11 and the second airflow from the second air outlet 21 can mix. The second airflow can be a non-heat exchange airflow. After being blown out, the first and second airflows can mix to form a mixed airflow. The temperature of the mixed airflow is closer to room temperature than that of the heat exchange airflow, resulting in higher comfort, a gentler breeze, increased air volume and speed, a longer air delivery distance, and better diffusion of the second airflow throughout the room.

[0054] In some embodiments of the present invention, such as Figure 1As shown, at the initial position, the second air outlet column 20 and the first air outlet column 10 form an air guiding interval 16, so that when the first air outlet 11 and / or the second air outlet 21 discharges air, the air in the air guiding interval 16 is driven to flow forward by the negative pressure. The air guiding interval 16 is formed between the first air outlet column 10 and the second air outlet column 20. In this way, when the first air outlet column 10 and / or the second air outlet column 20 discharges air, a negative pressure environment is formed at the air guiding interval 16, which promotes the indoor air at the rear of the 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, which makes the mixing amount of the indoor air larger and the mixing speed faster, forming a stronger air mixing effect. The temperature of the mixed air flow is closer to the room temperature than the heat exchange air flow, which is more comfortable, and the wind feeling is softer, which also increases the air volume and air speed, and the air supply distance is farther.

[0055] 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.

[0056] 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, which is significantly thinner than the first air outlet column 10. This asymmetric design not only meets the air discharge needs, but also makes the appearance of the air conditioner indoor unit more novel and unique, improving the competitiveness of the product.

[0057] For example, as shown in Figures 1 to 5 The ratio of the width of the second air outlet column 20 in the transverse direction to the width of the first air outlet column 10 in the transverse direction is less than 1 / 2. The ratio of the longitudinal depth of the second air outlet column 20 in the front-rear direction to the longitudinal depth of the first air outlet column 10 in the front-rear direction is less than 1 / 2, so as to form a double-column differentiated appearance. 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 of the two is not more than 10 cm, so that the non-heat exchange air flow and the heat exchange air flow 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 transverse direction; or in other words, the second air outlet column 20 is mostly or entirely located on one side of the first air outlet column 10 in the transverse direction.

[0058] 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 air flow after the heat exchanger 14 to flow out of the first air outlet 11. At this time, the first air flow is the heat exchange air flow. 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 which are arranged in sequence in the up-down direction.

[0059] 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 air flow 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.

[0060] In some embodiments of the present application, the first air outlet column 10 is provided with a first air guide member for guiding the lateral air outlet direction of the first air outlet 11. The first air guide member can include a plurality of lateral swing leaves 12, each of which can also be referred to as an air guide plate. "Guiding the lateral air outlet direction" means changing the included angle between the air outlet direction and the front-rear direction, such as making the air outlet air flow blow towards the front, towards the left front, towards the right front, etc. The second air outlet column 20 is provided with a second air guide member for guiding the lateral air outlet direction of the second air outlet 21. The second air guide member can include a plurality of lateral swing leaves 22. The main control board of the air conditioner can be electrically connected to the motors of the first air guide member and the first air guide member at the same time, so as to control the coordinated action of the two.

[0061] 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 air flow. The functional module 40 cooperates with the second air outlet column 20 to form at least a second air flow in 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.

[0062] 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 fresh air flow, a purifying air flow, a humidifying air flow, an oxygen adding air flow, and a water washing air flow mixed with indoor air, that is, the second air outlet 21 is simultaneously communicated with an indoor air inlet and the outlet of the functional module 40, and indoor air of the indoor air inlet is mixed with substances or gases 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 air quality.

[0063] In some embodiments of the present application, the second air outlet column 20 is rotatably arranged around a vertical axis. Preferably, the vertical axis passes through the second air outlet column 20, and the vertical axis is arranged at a position spaced 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, so that only the second air outlet column 20 is rotated, and the cross-flow fan does not need to rotate, which is simple in structure, convenient to control, and easy to implement. Further, the air conditioner indoor unit further comprises a rotating disc arranged at the lower side of the second air outlet column 20, and the rotating disc is rotatably arranged around the vertical axis, and the lower end of the second air outlet column 20 is rotatably arranged on the rotating disc around a horizontal axis.

[0064] 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.

[0065] Specifically, the air conditioner indoor unit blows out a first air flow by using the first air outlet column 10, and blows out a second air flow by using the second air outlet column 20, the second air flow is formed at least under the action of the functional module 40, and the first air flow and the second air flow are blown out separately, so that the additional functions of the air conditioner indoor unit do not have to depend on the heat exchange air duct. At the same time, the second air outlet column 20 can be rotated, which is convenient for the delivery of the second air flow. For example, when the requirements for the second air flow are relatively high, the delivery of the second air flow can be accelerated and the second air outlet column 20 can be rotated at the same time, so that the second air outlet column 20 can better diffuse to all parts of the room, and the effect of the functional module 40 can be improved, such as improving the humidifying / fresh air / dust removing / sterilizing / oxygen adding effect.

[0066] Further, as shown in FIG. 6, the air conditioner indoor unit further comprises a rotating disc arranged at the lower side of the second air outlet column 20, and the rotating disc is rotatably arranged around the vertical axis, and the lower end of the second air outlet column 20 is rotatably arranged on the rotating disc around a horizontal axis. Figure 1As shown, 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 enables the second air outlet column 20 to rotate to send out the second airflow; and the driving device 42 is started when the flow rate of the second airflow at the second air outlet 21 reaches a preset value.

[0067] Further, in some embodiments of the present application, the second air outlet column 20 can also rotate around the vertical axis when it is necessary to change the air mixing effect. In this way, the air outlet direction of the second airflow can be changed, and the air volume 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 second airflow is one or more of a mixed airflow of the new airflow, the purified airflow, the humidified airflow, the oxygenated airflow and the water-washed airflow 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.

[0068] In some embodiments of the present application, the functional module 40 comprises an airflow inlet and a second fan, and the second fan promotes the airflow to enter the airflow inlet and then flow out of the outlet of the functional module 40. For example, the functional module 40 is a new air module, etc. At this time, the air conditioner indoor unit can comprise the first fan 31, the second fan, the second air inlet 23 and the airflow inlet. The airflow inlet can be in communication with the second air inlet 23, so that the non-heat exchange airflow is one or more of the new airflow, the purified airflow, the humidified airflow, the oxygenated airflow and the water-washed airflow; or the airflow inlet and the second air inlet correspond to the non-heat exchange airflow which is one or more of the mixed airflow of the new airflow, the purified airflow, the humidified airflow, the oxygenated airflow and the water-washed airflow 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.

[0069] In some alternative embodiments of the present application, when the airflow 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 airflow 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.

[0070] 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, 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 indoor air from the second air inlet 23.

[0071] In some embodiments of the present application, as shown in FIG. 6, the air conditioner indoor unit further comprises a third air outlet column 30, and the third air outlet column 30 is arranged on the second air outlet column 20. The third air outlet column 30 is configured to rotate to send out the third airflow. The third air outlet column 30 is driven by a third driving device 32 to rotate to send out the third airflow. The third driving device 32 is started when the flow rate of the third airflow at the third air outlet 11 reaches a preset value. 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 communicated with 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.

[0072] 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 mixes into the air flow entering from the second air inlet to form a second air flow blowing 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 a counterclockwise direction or in a 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 at the position for a period of time.

[0073] 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.

[0074] 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.

[0075] 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 outflow direction of the first air flow outflowing from 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 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 first air flow blown from the first air outlet 11 from directly blowing the person at the user position, and further the user position can be detected by the 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.

[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 also has a fourth position at which the second air outlet 21 can be rotated to a position aligned with the first air outlet 11 to achieve mutual blowing of the first air outlet 11 and the second air outlet 21, and the impurities on the filter screen at the first air inlet 13 can be removed, or the impurities on the filter screen at the second air inlet 23 can be removed. In particular, the air flow outflowing from the second air outlet 21 is a non-heat exchange air flow, and the non-heat exchange device can be used to directly blow the first air outlet 11 at the area prone to condensation, etc., to prevent or remove the condensation, and further the condensation on the heat exchanger 14, etc., can also be removed.

[0077] In some embodiments of the present application, the second air outlet column 20 has an initial position, and the second air outlet column 20 also has a fifth 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 also has a sixth position at which the second air inlet 23 can be rotated to a position aligned with the first air outlet 11.

[0078] Further, the second air outlet column 20 can be moved to the above-mentioned initial position, the second position, the third position, the fourth position, the fifth position and the sixth position, and of course can also be moved 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 collinear with the connecting line of the two opposite corners 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 exchanger fan.
