The embodiment of the invention provides an air conditioner indoor unit, which is an indoor part of a split air conditioner and is used for adjusting indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like. The indoor unit of the air conditioner can be a floor cabinet machine or a vertical wall-mounted machine.
Fig. 1 is a schematic front view of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown in fig. 1, and referring to fig. 2 to 5, an indoor unit of an air conditioner according to an embodiment of the present invention includes a first air outlet column 10 and a second air outlet column 20.
The first air outlet column 10 is in a vertical column shape, a first air outlet 11 for blowing out first air flow is formed in the front side of the first air outlet column 10, and the first air outlet 11 is in a vertical strip shape. The second air outlet column 20 is in a vertical column shape, a second air outlet 21 for blowing out second air flow is formed in the front side of the second air outlet column 20, and the second air outlet 21 is in a vertical strip shape. The second air outlet columns 20 and the first air outlet columns 10 are arranged along the transverse direction, and the left-right direction perpendicular to the front-rear direction of the indoor unit of the air conditioner is the transverse direction.
Specifically, the first air flow is a heat exchange air flow. "heat exchange air flow" refers to an air flow that performs heat exchange with the heat exchanger 14 of the air conditioner for adjusting the indoor temperature. The heat exchanger 14 is connected with a compressor, a heat exchanger of an outdoor unit, a throttling device and other refrigerating elements through pipelines to form a vapor compression refrigeration cycle system. When the air conditioner indoor unit is in a refrigerating 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 air is blown to the indoor environment through the first air outlet 11, and refrigeration and heating of the indoor environment are completed. The second air flow is non-heat exchange air flow and has the function of auxiliary regulation on the indoor environment.
When the indoor unit of the air conditioner of the embodiment of the invention operates, the first air outlet column 10 and the second air outlet column 20 can be selectively or simultaneously started for supplying air. The first air outlet column 10 and the second air outlet column 20 can be opened at the same time. The air conditioning indoor unit of the embodiment of the invention utilizes the first air outlet column 10 to blow out the first air flow, the first air flow can be heat exchange air flow, and utilizes the second air outlet column 20 to blow out the second air flow, and the first air flow and the second air flow are independently blown out, so that the additional function of the air conditioning indoor unit is not required to be attached to a heat exchange air duct.
In this embodiment of the present invention, the first air outlet 11 is directed forward and toward the second air outlet post 20, i.e., the first air outlet 11 is directed obliquely forward, and the second air outlet 21 is directed forward and toward the first air outlet post 10, i.e., the second air outlet 21 is directed obliquely forward. The front side of the first air outlet column 10 is provided with a display device 18, and the display device 18 is positioned on one side of the first air outlet 11, which is away from the second air outlet 21. And, the lower end or the upper end of the second air outlet column 20 is rotatably arranged around a horizontal axis, and the horizontal axis 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 to cover a part of the area of the first air outlet.
The second air outlet column 20 is obliquely arranged, and the partial area of the first air outlet 11 can be shielded, such as the area with the highest air outlet temperature and the lowest area of the first air outlet 11, so that the air outlet temperature of the first air outlet 11 is more uniform, the comfort level of a user is improved, and the shielding can be performed according to the requirement of the user, so that the effect of improving the user experience is achieved.
As shown in fig. 3 to 5, the indoor unit of the air conditioner further includes a plurality of temperature sensors sequentially disposed at the first air outlet 11 along the vertical direction, so as to detect the air outlet temperatures of the first air outlet 11 along the upper and lower portions, and further rotate the second air outlet column 20 to the front side of the region of the first air outlet 11 corresponding to the corresponding air outlet temperature according to the air outlet temperatures. Specifically, the first air outlet 11 is divided into six areas such as A, B, C, D, E, F, and the air outlet temperatures of the six areas are detected by six temperature sensors respectively. During heating, the second air outlet column 20 rotates to the front side of the region of the first air outlet 11 corresponding to the lowest air outlet temperature, and during cooling, the second air outlet column 20 rotates to the front side of the region of the first air outlet 11 corresponding to the highest air outlet temperature.
In some embodiments of the present invention, as shown in fig. 1, at the initial position, the first air flow flowing out of the first air outlet 11 and the second air flow flowing out of the second air outlet 21 may be mixed. The second air flow can be non-heat exchange air flow, the first air flow and the second air flow can be mixed after being blown out to form mixed air flow, the temperature of the mixed air flow is closer to the room temperature than that of the heat exchange air flow, the comfort is higher, the wind sense is softer, the wind quantity and the wind speed are increased, the air supply distance is farther, and the second air flow can be better diffused to all parts in a room.
In some embodiments of the present invention, as shown in fig. 1, at the initial position, an induced air space 16 is formed between the second air outlet pillar 20 and the first air outlet pillar 10, so that when the first air outlet 11 and/or the second air outlet 21 outlet air, the air in the induced air space 16 is driven to flow forward by the action of negative pressure. An induced air space 16 is formed between the first air outlet post 10 and the second air outlet post 20. In this way, when the first air outlet column 10 and/or the second air outlet column 20 is/are air-out, a negative pressure environment is formed at the air inducing interval 16, so that the indoor air behind the indoor unit of the vertical air conditioner is caused to flow forward through the air inducing interval 16 to mix into the air outlet 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, and forms a stronger air mixing effect. Compared with the heat exchange air flow, the temperature of the air mixing air flow is closer to the room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer.
In some embodiments of the present invention, as shown in fig. 1, the first air outlet 11 and the second air outlet 21 may be in an overall vertical strip shape extending from top to bottom, or may be in an intermittent vertical strip shape formed by a plurality of vertically arranged sub air outlets.
In some embodiments of the present invention, since the heat exchanger 14 is not required to be disposed in the second air outlet column 20, the second air outlet column 20 can be designed to be thinner than the first air outlet column 10, and the asymmetric design not only meets the air outlet requirement, but also makes the appearance of the indoor unit of the air conditioner more novel and unique, and improves the competitiveness of the product.
For example, as shown in fig. 1 to 5, the ratio of the width of the second air outlet post 20 in the lateral direction to the width of the first air outlet post 10 in the lateral direction may be made smaller than 1/2. The ratio of the depth dimension of the second air outlet post 20 in the front-rear direction to the depth dimension of the first air outlet post 10 in the front-rear direction is less than 1/2 to form a double post differentiated appearance. The second air outlet 21 may be flush or substantially flush with the front-to-back position of the first air outlet 11, for example, no more than 10cm from front-to-back, so that the non-heat exchanging air flow and the heat exchanging air flow are better mixed. That is, the second air outlet leg 20 is located mainly on one lateral side of the front half of the first air outlet leg 10, or, the second air outlet leg 20 is located mostly or entirely on one lateral side of the front half of the first air outlet leg 10.
In some embodiments of the present invention, as shown in fig. 2, a 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 internally provided with a heat exchanger 14 and a heat exchange fan 15, and the heat exchange fan 15 flows out of the first air outlet 11 through the heat exchange air flow after passing through the heat exchanger 14, and at the moment, the first air flow is the heat exchange air flow. The heat exchange fan is preferably a cross flow fan, and in some alternative embodiments, the heat exchange fan 15 may be a plurality of axial flow fans or centrifugal fans arranged in sequence in the up-down direction.
In some embodiments of the present invention, as shown in fig. 2, a second air inlet 23 communicating with the second air outlet 21 is provided at the rear side of the second air outlet 20. The second air outlet column 20 is internally provided with a vertical strip-shaped air channel which is communicated with the second air inlet 23 and the second air outlet 21. The air duct is internally provided with a first fan 31, the first fan 31 enables air flow to enter the air duct from the second air inlet 23 and then flow out from the first air outlet 11, and the first fan 31 is a cross-flow fan.
In some embodiments of the present invention, a first air guiding member for guiding a lateral air outlet direction of the first air outlet 11 is mounted on the first air outlet column 10. The first air guide may include a plurality of transverse vanes 12, each of which may also be referred to as an air deflector. By "directing the lateral air-out direction" is meant changing the angle of the air-out direction to the front-to-back direction, e.g., directing the air-out flow straight ahead, left-to-front, right-to-front, etc. 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 wind guide may include a plurality of lateral swing blades 22. The main control board of the air conditioner can be electrically connected with the first air guide piece and the motor of the first air guide piece at the same time so as to control the two to act cooperatively.
In some embodiments of the present invention, the air conditioning indoor unit further includes a functional module 40. The functional module 40 is configured for treating gas flowing therethrough or adding substances to the gas flow, the functional module 40 cooperating with the second outlet leg 20 to form a second gas flow at least within the second outlet leg 20. The outlet of the functional module 40 is communicated with the upper end or the lower end of the air duct, or the outlet of the functional module 40 is communicated with the second air inlet 23.
The functional module 40 is one or more of a fresh air device, an oxygenation device, a purification device, a humidification 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 fresh air flow, purified air flow, humidifying air flow, oxygenation air flow and water washing air flow. When the outlet of the functional module 40 is connected to the upper end or the lower end of the air duct, the corresponding non-heat-exchanging air flow is a mixed air flow formed by one or more of fresh air flow, purified air flow, humidified air flow, oxygenation air flow and water washing air flow and indoor air, that is, the second air outlet 21 is simultaneously connected to an indoor air inlet and the outlet of the functional module 40, and the indoor air of the indoor air inlet is mixed with substances or gases from the functional module 40. Further, the purifying device has dust removing and/or sterilizing functions, i.e. the purifying device is a dust removing device, a sterilizing device or a device with dust removing and sterilizing functions at the same time. Of course, other functional modules 40 that can change the air quality can be used for the functional module 40.

Preferably, a vertical axis passes through the second air outlet column 20, and is spaced from the second air outlet 21, although the vertical axis may be located at other positions. Preferably, the vertical axis is the axis of the first fan 31, so that the second air outlet column 20 can be rotated only, the through-flow fan does not need to follow rotation, and the structure is simple, the control is convenient, and the implementation is easy. Further, the indoor unit of the air conditioner further comprises a rotary table, wherein the rotary table is arranged at the lower side of the second air outlet column 20 and is rotatably arranged around the vertical axis, and the lower end of the second air outlet column 20 is rotatably arranged on the rotary table around the horizontal axis.
When the indoor unit of the air conditioner of the embodiment of the invention operates, the first air outlet column 10 and the second air outlet column 20 can be selectively or simultaneously started for supplying air. The second air outlet column 20 can be rotated to a preset position to blow according to the requirement, or the second air outlet column 20 can be rotated at the time of blowing, and can be rotated clockwise or counterclockwise.
Specifically, the air conditioning indoor unit utilizes the first air outlet column 10 to blow out a first air flow, the first air flow can be a heat exchange air flow, and utilizes the second air outlet column 20 to blow out a second air flow, 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 independently, so that the additional function of the air conditioning indoor unit is not required to be attached to a heat exchange air duct. Meanwhile, the second air outlet column 20 can rotate, so that the conveying of the second air flow is facilitated. For example, when the requirements for the second air flow are relatively high, the second air flow is accelerated to be conveyed and the second air outlet column 20 is rotated at the same time, so that the second air outlet column can better diffuse to various indoor places, and the effect of the functional module 40, such as humidification/fresh air/dust removal/sterilization/oxygenation, is improved.
Further, as shown in fig. 1, the indoor unit of the air conditioner further includes a driving device 42, where the driving device 42 is configured to drive the second air outlet column 20 to rotate.

Further, in some embodiments of the present invention, the second air outlet post 20 may also be made rotatable about a vertical axis when it is desired to change the mixing effect. The air outlet direction of the second air flow can be changed, the air quantity is changed, different air outlet effects are obtained, more air outlet modes are obtained, individual demands of users are met, and the use experience of the users is improved. Preferably, the second air flow is a mixed air flow formed by one or more of fresh air flow, purified air flow, humidifying air flow, oxygen adding air flow and water washing air flow and indoor air, namely when the second air outlet column 20 also blows out indoor air, a stronger air mixing effect can be achieved, so that the air flow is closer to room temperature.
In some embodiments of the present invention, the functional module 40 includes an airflow inlet and a second fan that causes airflow into the airflow inlet and then out of the outlet of the functional module 40. For example, the functional module 40 is a fresh air module or the like. At this time, the air conditioning indoor unit may include a first fan 31, a second fan, a second air inlet 23, and an airflow inlet. The air inlet may be in communication with the second air inlet 23 such that the non-heat exchanging air flow is one or more of a fresh air flow, a purified air flow, a humidified air flow, an oxygen-enriched air flow and a water-washing air flow, or the air inlet and the second air inlet may correspond to the non-heat exchanging air flow being a mixed air flow formed by one or more of a fresh air flow, a purified air flow, a humidified air flow, an oxygen-enriched air flow and a water-washing air flow and indoor air. Further, the material from the functional module 40 may be located at one side or the other of the first fan 31 facing the second air outlet 21.
In alternative embodiments of the present invention, only one of the first fan 31 and the second fan may be selected when the airflow inlet communicates with the second air inlet 23.

The indoor unit of the air conditioner may have an operation mode in which neither the functional module 40 nor the first fan 31 operates when the indoor humidity is less than the first preset humidity. When the indoor humidity is less than the second preset humidity and the indoor humidity is greater than the first preset humidity, the functional module 40 operates and the first fan 31 operates at a low speed. When the indoor humidity is less than the third preset humidity and the indoor humidity is greater than the second preset humidity, the functional module 40 operates and the first fan 31 operates at a high speed. 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, so that the moisture is blown to the periphery in a rotating manner, the humidifying effect is improved, and the second air outlet column 20 continuously rotates and can rotate counterclockwise or clockwise.
