DESCRIPTION OF EMBODIMENTS

Embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference signs. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the present disclosure.
An air-conditioning indoor unit 100 according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings. Dashed arrows in each of FIG. 3 to FIG. 10 illustrate a flow direction of an airflow.
Referring to FIG. 1 and FIG. 4, according to an embodiment in a first aspect of the present disclosure, the air-conditioning indoor unit 100 includes a surface frame 1, a breezeless member 2, a heat exchanger 3, and a fan 4. The surface frame 1 has an air inlet 10 defined thereon and a first air outlet 11 defined on a front lower part thereof. The first air outlet 11 forwardly penetrates a front part of the surface frame 1 and downwardly penetrates a bottom of the surface frame 1. The breezeless member 2 is configured to scatter air, and is arranged at a front side of the surface frame 1 in a manner that the breezeless member 2 is movable the between a first position and a second position. For example, the first air outlet 11 extends in a leftward-rightward direction, and the breezeless member 2 is movable in an upward-downward direction. The breezeless member 2 is capable of moving downwardly to the second position when the breezeless member 2 is located at the first position, and moving upwardly to the first position when the breezeless member 2 is located at the second position. The outer deflector 12 is movably disposed at the first air outlet 11. The outer deflector 12 is capable of opening and closing a bottom side of the first air outlet 11. Both the heat exchanger 3 and the fan 4 are disposed within the surface frame 1. The fan 4 is capable of driving an external airflow to enter the air-conditioning indoor unit 100 from the air inlet 10. The external airflow is then heat exchanged with the heat exchanger 3. The heat exchanged airflow may be discharged from the first air outlet 11. Here, the airflow may not only be discharged forwardly from the front part of the surface frame 1, but also be discharged downwardly from the bottom of the surface frame 1. An airflow from the air-conditioning indoor unit 100 may be discharged forwardly and downwardly from the first air outlet 11 simultaneously to increase an outlet air volume and an outlet air coverage of the air-conditioning indoor unit 100.
In an embodiment, the air-conditioning indoor unit 100 includes a drive assembly 24 configured to drive the breezeless member 2. The drive assembly 24 may be disposed on the surface frame 1, and is capable of driving the breezeless member 24 to move in the upward-downward direction, thereby realizing a movement of the breezeless member 2 between the first position and the second position.
The front side of the first air outlet 11 is opened by the breezeless member 2 in the first position. In this case, the front side of the first air outlet 11 is completely opened by the breezeless member 2 to discharge the air from the front side of the first air outlet 11, and the air-conditioning indoor unit 100 has a large outlet air volume. The front side of the first air outlet 11 is closed by the breezeless member 2 in the second position. In this case, the front side of the first air outlet 11 is completely closed the breezeless member 2. An airflow discharged from the front side of the first air outlet 11 may all pass through the breezeless member 2. Since the breezeless member 2 can scatter the air, the air is blown gently by the front side of the first air outlet 11 to realize breezeless air blowing, which prevents cold air from blowing directly across the human body in a cooling mode of the air-conditioning indoor unit 100, and improves user comfort.
The outer deflector 12 is movably disposed at the first air outlet 11. The outer deflector 12 is capable of opening and closing a bottom side of the first air outlet 11. The outer deflector 12 is capable of opening, partially opening, or closing the bottom side of the first air outlet 11. When the bottom side of the first air outlet 11 is opened by the outer deflector 12, the air is discharged from the bottom side of the first air outlet 11 to allow a large volume of air to be blown from the bottom side of the first air outlet 11. The bottom side of the first air outlet 11 can be effectively closed when the bottom side of the first air outlet 11 is closed by the outer deflector 12. In an embodiment, when a user needs a small volume of air to be blown or the user only needs the air to be discharged from the front side of the surface frame 1, the bottom side of the first air outlet 11 can be closed by the outer deflector 12.
When the air-conditioning indoor unit 100 is in operation, the breezeless member 2 is at the first position. When the bottom side of the first air outlet 11 is opened by the outer deflector 12, the air can be blown from both the front side and the bottom side of the first air outlet 11 by a large volume of air. The air blown by the air-conditioning indoor unit 100 is discharged from the front side and the bottom side of the first air outlet 11 simultaneously, in which case the air-conditioning indoor unit 100 can realize quick cooling or heating. When the breezeless member 2 is in the first position and the bottom side of the first air outlet 11 is partially opened by the outer deflector 12, the air is blown from the front side of the first air outlet 11 by a large volume of air, and the air is blown from the bottom side of the first air outlet 11 by a small volume of air. The air blown by the air-conditioning indoor unit 100 is mainly discharged from the front side of the first air outlet 11. In this case, the air-conditioning indoor unit 100 is suitable for cooling, and the cold air is mainly discharged from the front side of the first air outlet 11. Such a manner is conducive to uniform indoor cooling. When the breezeless member 2 is at the first position and the bottom side of the first air outlet 11 is closed by the outer deflector 12, the air is blown from the front side of the first air outlet 11 by a large volume of air, and no air is blown from the bottom side of the first air outlet 11. In this case, the air-conditioning indoor unit 100 is suitable for cooling, and the cold air is all discharged from the front side of the first air outlet 11. Such a manner is conducive to uniform indoor cooling.
When the breezeless member 2 is in the second position and the bottom side of the first air outlet 11 is opened by the outer deflector 12, the air is blown gently from the front side of the first air outlet 11, and the air is blown from the bottom side of the first air outlet 11 by a large volume of air. Therefore, the air-conditioning indoor unit 100 blows a large volume of air while operating in a breezeless mode. In this case, the air-conditioning indoor unit 100 is suitable for quick cooling, and also can prevent cold air from blowing directly across the human body. When the breezeless member 2 is in the second position and the bottom side of the first air outlet 11 is partially opened by the outer deflector 12, the air is blown gently from the front side of the first air outlet 11, and the air is blown from the bottom side of the first air outlet 11 by a small volume of air. In this case, the air-conditioning indoor unit 100 is suitable for cooling and for a situation where the user has a small demand for a cooling capacity. Meanwhile, it is possible to prevent the cold air from blowing directly across the human body. When the breezeless member 2 is in the second position and the bottom side of the first air outlet 11 is closed by the outer deflector 12, the air is blown gently from the front side of the first air outlet 11, and no air is blown from the bottom side of the first air outlet 11. In this case, the air-conditioning indoor unit 100 is suitable for cooling and for a situation where the user has a small demand for a cooling capacity. The air is blown gently from the air-conditioning indoor unit 100, which can prevent the cold air from blowing directly across the human body.
Air blowing modes of the air-conditioning indoor unit 100 are diversified through different cooperating manners between the breezeless member 2 and the outer deflector 12. Especially in the breezeless mode, the volume of the air blown by the air-conditioning indoor unit 100 may be adjusted by the outer deflector 12 to meet the user's requirements for different air output effects and regulation of an indoor temperature of the air-conditioning indoor unit 100.
When at the second position, the breezeless member 2 allows the air discharged from the front side of the first air outlet 11 to be blown gently. The air-conditioning indoor unit 100 may also blow the air from the bottom side of the first air outlet 11 simultaneously, even if the volume of the air blown from the front side of the first air outlet 11 is reduced when the breezeless member 2 blocks the air blown from the front side of the first air outlet 11. In this case, the air-conditioning indoor unit 100 can discharges a large total volume of the air through the first air outlet 11. Therefore, the air-conditioning indoor unit 100 has a large total volume of air while the air blown by the air-conditioning indoor unit 100 is not blown directly across the human body, in which case an indoor temperature can be adjusted quickly and the user experience can be improved.
According to the air-conditioning indoor unit 100 according to the embodiments of the present disclosure, the first air outlet 11 is defined on the front lower part of the surface frame 1. The first air outlet 11 forwardly penetrates the front part of the surface frame 1 and downwardly penetrates the bottom of the surface frame 1 to allow the air-conditioning indoor unit 100 to blow air from the front part and the bottom of the surface frame 1 simultaneously. In this manner, an outlet air volume and an outlet air coverage are increased. The front side of the first air outlet 11 can be closed by the breezeless member 2 in the second position. Thus, it is possible to prevent the cold air from being blown directly across the human body, and the air is blown gently, thereby realizing the breezeless air blowing mode. In addition, the air-conditioning indoor unit 100 has a large refrigerating capacity in the breezeless mode. Through different cooperating manners between the breezeless member 2 and the outer deflector 12, air blowing modes of the air-conditioning indoor unit 100 are diversified to better meet the user's requirements for different air blowing effects and regulation of the indoor temperature of the air-conditioning indoor unit 100.
Referring to FIG. 1 to FIG. 3, according to some embodiments of the present disclosure, the surface frame 1 has a second air outlet 13 defined on at least one of a left end or a right end thereof. In an embodiment, the second air outlet 13 is defined on the left end of the surface frame 1. During air blowing of the air-conditioning indoor unit 100, when the bottom side of the first air outlet 11 is at least partially opened by the outer deflector 12, the air may be blown forwards, downwards, and leftwards to form three-dimensional (3D) air blowing. In an embodiment, the second air outlet 13 is defined on the right end of the surface frame 1. During air blowing of the air-conditioning indoor unit 100, when the bottom side of the first air outlet 11 is at least partially opened by the outer deflector 12, the air may be blown forwards, downwards, and rightwards to form 3D air blowing. In an embodiment, the second air outlet 13 is defined on each of the left end and the right end of the surface frame 1. When the bottom side of the first air outlet 11 is at least partially opened by the outer deflector 12, during air blowing of the air-conditioning indoor unit 100, the air may be blown forwards, downwards, leftwards, and rightwards to form four-dimensional (4D) air blowing. By forming the second air outlet 13, it is possible to increase the outlet air coverage of the air-conditioning indoor unit 100, realize multi-orientation air blowing of the air-conditioning indoor unit 100, and is conducive to increase a volume of the air blown by the air-conditioning indoor unit 100.
Referring to FIG. 1 to FIG. 4, according to some embodiments of the present disclosure, the surface frame 1 has a panel 5 provided at the front side thereof. A receiving chamber 51 is defined between the panel 5 and the surface frame 1. The breezeless member 2 in the first position is received within the receiving chamber 51. Such a design makes it easy to store the breezeless member 2 when the breezeless member 2 is at the first position, thereby realizing full use of an internal space of the air-conditioning indoor unit 100, and providing a compact structure for the air-conditioning indoor unit 100.
Referring to FIG. 1, according to some embodiments of the present disclosure, when the air-conditioning indoor unit 100 is in an OFF state, the bottom side of the first air outlet 11 is closed by the outer deflector 12, and the front side of the first air outlet 11 is closed by the breezeless member 2. Such a design can prevent dust or foreign objects from entering the air-conditioning indoor unit 100 via the first air outlet 11 when the air-conditioning indoor unit 100 is turned off. Meanwhile, such a design can also make the air-conditioning indoor unit 100 aesthetically pleasing. The breezeless member 2 abuts the outer deflector 12 by an abutting line located at a front side of the first air outlet 11. Here, the breezeless member 2 abutting the outer deflector 12 means that the breezeless member 2 and the outer deflector 12 abut each other. In an embodiment, a small gap may be formed between the breezeless member 2 and the outer deflector 12, or the breezeless member 2 may be in contact with the outer deflector 12.
Referring to FIG. 5 and FIG. 6, according to some embodiments of the present disclosure, the air-conditioning indoor unit 100 has a first operation mode group. In the first operation mode group, the front side of the first air outlet 11 is opened by the breezeless member 2, and the bottom side of the first air outlet 11 is at least partially opened by the outer deflector 12. In this case, the air is blown from the front side portion of the first air outlet 11 by a large volume of air, which may be further regulated by adjusting the outer deflector 12. In an embodiment, the bottom side of the first air outlet 11 is partially opened by the outer deflector 12, and thus the air is blown from the bottom side of the first air outlet 11 by a small volume of air; or the bottom side of the first air outlet 11 is opened by the outer deflector 12, and thus the air is blown from the bottom side of the first air outlet 11 by a large volume of air. In the first operation mode group, forward air blowing by the air-conditioning indoor unit 100 is not affected by the breezeless member 2, in which manner the air-conditioning indoor unit 100 can blows a large volume of air, and the outer deflector 12 can further regulate the volume of the air blown from the first air outlet 11.
Referring to FIG. 5 and FIG. 6, further, the first operation mode group includes at least one of a first operation mode and a second operation mode. In an embodiment, the first operation mode group includes the first operation mode; or the first operation mode group includes the second operation mode; or the first operation mode group includes both the first operation mode and the second operation mode. In the first operation mode, the front side of the first air outlet 11 is opened by the breezeless member 2, and the bottom side of the first air outlet 11 is partially opened by the outer deflector 12 (reference may be made to a flow direction of an airflow indicated by dashed arrows in FIG. 5). In this case, the air blown by the air-conditioning indoor unit 100 is discharged from the front side of the first air outlet 11, and the breezeless member 2 does not affect the air discharged from the front side of the first air outlet 11. In such an operation mode, the air is blown from the front side of the first air outlet 11 by a large volume of air, and the air is blown from the bottom side of the first air outlet 11 by a small volume of air. Therefore, the air-conditioning indoor unit 100 mainly blows air forwardly, but also blows air downwardly. In the second operation mode, the front side of the first air outlet 11 is opened by the breezeless member 2, and the bottom side of the first air outlet 11 is opened by the outer deflector 12, and the air blown from the first air outlet 11 is guided by moving and positioning the outer deflector 12 at the front side of the first air outlet 11 (reference may be made to a flow direction of an airflow indicated by dashed arrows in FIG. 6). In this case, the air blown by the air-conditioning indoor unit 100 is discharged from the bottom side of the first air outlet 11. In such an operation mode, the air is blown from the front side of the first air outlet 11 by a small volume of air, and the air is blown from the bottom side of the first air outlet 11 by a large volume of air. Therefore, the air-conditioning indoor unit 100 can blow air forwardly and downwardly simultaneously.
Referring to FIG. 7 and FIG. 8, according to some embodiments of the present disclosure, the air-conditioning indoor unit 100 has a second operation mode group. In the second operation mode group, the front side of the first air outlet 11 is closed by the breezeless member 2, and the bottom side of the first air outlet 11 is at least partially closed by the outer deflector 12.

In an embodiment, the bottom side of the first air outlet 11 is partially closed by the outer deflector 12 to allow the air to be blown from the bottom side of the first air outlet 11; or the bottom side of the first air outlet 11 is closed by the outer deflector 12 to prevent the air from being blown from the bottom side of the first air outlet 11. In the second operation mode group, since the breezeless member 2 can scatter the air, the air is blown gently from the front side of the first air outlet 11 to realize breezeless air blowing. An outlet air volume in the breezeless mode may be adjusted by altering a position of the outer deflector 12. In this case, cold air can be prevented from blowing directly across the human body during the cooling operation of the air-conditioning indoor unit 100, and a total outlet air volume of the air-conditioning indoor unit 100 can be adjusted.

In this case, the air-conditioning indoor unit 100 blows air from the front side of the first air outlet 11 gently. In the third operation mode, the air-conditioning indoor unit 100 can blow the air forwardly. In the fourth operation mode, the front side of the first air outlet 11 is closed by the breezeless member 2, and the outer deflector 12 abuts the breezeless member 2 at one end thereof and is spaced apart from the bottom portion of the surface frame 1 at the other end thereof to partially open the bottom side of the first air outlet 11 (reference may be made to a flow direction of an airflow indicated by dashed arrows in FIG. 8). In this case, the air blown by the air-conditioning indoor unit 100 is partially discharged from the front side of the first air outlet 11 and partially discharged from the bottom side of the first air outlet 11. The air discharged from the front side of the first air outlet 11 is blown gently, while an airflow is discharged from the bottom side of the first air outlet 11, in which case the air is discharged from the first air outlet 11 of the air-conditioning indoor unit 100 by a large volume of air. Therefore, the total outlet air volume of the air-conditioning indoor unit 100 is large while preventing the air blown from the air-conditioning indoor unit 100 from being blown directly across the human body, which can adjust the indoor temperature quickly and improve the user experience.
Referring to FIG. 4 to FIG. 8, according to some embodiments of the present disclosure, the outer deflector 12 is rotatably disposed at the first air outlet 11.

The inner deflector 1411 is configured to guide the airflow (the inner deflector 1411 guides the airflow to different directions when rotated to different angles; and reference in this regard may be made to FIG. 5 to FIG. 11 regarding guidance of the inner deflector 1411 on the airflow when the inner deflector 1411 is rotated to different positions). The inner deflector 1411 is capable of adjusting the flow direction of the airflow. In an embodiment, when the inner deflector 1411 is rotated to extend in a substantially horizonal direction, the inner deflector 1411 can guide the airflow to flow forwards. Since the airflow from the front side of the first air outlet 11 is discharged substantially forwards, most of the airflow in the air outlet passage 14 is discharged forwards from the front side of the first air outlet 11, and a small part of the airflow in the air outlet passage 14 is discharged downwards from the bottom side of the first air outlet 11. In an embodiment, when the inner deflector 1411 is rotated to extend in a substantially vertical direction, the inner deflector 1411 can guide the airflow to flow downwards. Since the airflow from the front side of the first air outlet 11 is discharged substantially downwards, most of the airflow in the air outlet passage 14 is discharged downwards from the bottom side of the first air outlet 11, and a small part of the airflow in the air outlet passage 14 is discharged forwards from the front side of the first air outlet 11. The inner deflector 1411 has a rotation axis located at or close to a middle thereof. Therefore, the inner deflector 1411 occupies a small space when rotated, which facilitates arranging other components inside the air-conditioning indoor unit 100.
Referring to FIG. 4 to FIG. 10, according to some embodiments of the present disclosure, the rotatable flow guide device 141 includes an inner deflector 1411 that is rotatable, and a louver 1412 disposed on the inner deflector 1411.

The link passes through the louver 1412, and is movable in the leftward-rightward direction to drive the louver 1412 to sway in the leftward-rightward direction. The inner deflector 1411 can guide the airflow. Rotating the inner deflector 1411 may adjust the flow direction of the airflow in the upward-downward direction, and the louver 1412 may adjust the flow direction of the airflow in the leftward-rightward direction. Therefore, by designing the rotatable flow guide device 141 to include the rotatable inner deflector 1411 and the louver 1412 disposed on the inner deflector 1411, the rotatable flow guide device 141 can guide the airflow in several directions. In addition, by integrating the louver 1412 on the inner deflector 1411, it is possible to decrease an occupation space and provide the whole machine with a compact structure.
Referring to FIG. 4 to FIG. 10, according to some embodiments of the present disclosure, when the air-conditioning indoor unit 100 is in an OFF state, the rotatable flow guide device 141 can close an air outlet end of the air outlet passage 14.
