Those of ordinary skill in the art will understand the specific meaning of the terms described above in the present invention as the case may be.
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 7, the embodiment of the present invention provides an indoor unit of an air conditioner, which 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 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 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. When the second air outlet column 20 is at the initial position, it 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 indoor unit of the air conditioner is the transverse direction.
Specifically, the air flow flowing out of the first air outlet 11 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 air flow flowing out of the second air outlet 21 is a non-heat exchange air flow, and the function of the air flow is to assist in adjusting 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.
In this embodiment of the invention, in particular, the second air outlet post 20 is movably arranged and the second air outlet post 20 is rotatably arranged about a vertical axis. For example, the second air outlet column 20 can be driven to move and rotate by a driving device. The driving device is configured to drive at least the second air outlet post to move from the initial position to the preset position, and enable the second air outlet post to rotate around the vertical axis, so that the second air outlet is aligned with the first air outlet when being at the preset position, and then air flow flowing out of the first air outlet 11 enters the second air outlet post 20 through the second air outlet 21, or air flow flowing out of the second air outlet 21 enters the first air outlet post 10 through the first air outlet 11, as shown in fig. 3.
Through setting up drive arrangement, can make the second air outlet aim at first air outlet, and then make non heat transfer air current get into first air outlet 11, remove dust to the filter screen that first air intake 13 department set up, also can make non heat transfer air current get rid of the condensation of first air outlet 11 departments, make the function of air conditioning indoor unit not be single, have multiple functions, improve the practicality of air conditioning indoor unit. No special equipment is arranged for dust removal and the like, so that the cost is low and the energy is saved. In some alternative embodiments of the present invention, the second outlet leg 20 may be in other positions when in the initial position, such as the position shown in fig. 4, and so on.
Further, in some embodiments of the present invention, the second air outlet post 20 may have at least three positions to meet different air supply requirements. For example, the driving device includes a rail 50 and a slider disposed on the rail 50, and the second air outlet column casing 20 is rotatably mounted on the slider. The second outlet leg 20 may stay at any position on the track as shown in fig. 3 to 7, and may also rotate.
In some embodiments of the present invention, track 50 includes a first track segment 51 and a second track segment 52. The first rail section 51 extends in the lateral direction and is disposed on the front side of the first air outlet post 10. The front end of the second track section 52 is connected to one end of the first track section 51 adjacent to the second air outlet post 20, the second track section 52 extends from the front end to the rear end in a direction away from the first air outlet post 10 in a tilting manner, and the preset position is the connection position of the first track section 51 and the second track section 52. In some alternative embodiments of the invention, the ends of the track are connected to wrap around the first outlet post 10 for a revolution, such as a circle coaxial with the axis of rotation of the heat exchange fan.
In the embodiment of the present invention, the second air outlet post 20 has at least two relative positions with respect to the first air outlet post 10. For example, the second air outlet pillar 20 further has a position in the outflow 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 blowing straight. Also for example, the second air outlet column 20 further has a position between the first air outlet 11 and the user position to shield the first air outlet 11, prevent the blown air flow of the first air outlet 11 from blowing directly against the person at the user position, further detect the user position through human sense, and then control the second air outlet column 20 to move between the user position and the first air outlet 11. For another example, the second air outlet 21 may be rotated to be aligned with the first air inlet 13, or the second air inlet 23 may be rotated to be aligned with the first air outlet 11.
In some embodiments of the present invention, at the initial position of the second air outlet post, the first air outlet 11 faces forward and faces the second air outlet post 20, i.e. the first air outlet 11 faces obliquely forward, and the second air outlet 21 faces forward and faces the first air outlet post 10, i.e. the second air outlet 21 faces obliquely forward. Further, the rear side edge of the second air outlet 21 is located at the front side of the rear side edge of the first air outlet 11, and the front side edge of the second air outlet 21 is located at the rear side of the front side edge of the first air outlet 11. The front side of the first air outlet column 10 is provided with a display device 18, and the display device 18 is positioned on one side of the first air outlet 11, which is away from the second air outlet 21.
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 first air deflectors 12. 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 air guide may include a plurality of second air deflectors 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 particular, when the second air outlet is aligned with the first air outlet, the first air deflector is perpendicular to the plane where the first air outlet is located, and the first air deflector and the second air deflector may be parallel to guide the airflow flowing out of the first air outlet 11 to flow into the second air outlet 21 or guide the airflow flowing out of the second air outlet 21 to flow into the first air outlet 11.
In some embodiments of the present invention, the number of the first air deflectors 12 is at least two, and the rotation axis of the first air deflector 12 at the rearmost side is located at the rear side edge of the first air outlet, or the distance between the rotation axis of the first air deflector 12 at the rearmost side and the rear side edge of the first air outlet is smaller than the distance between the rotation axis of the first air deflector 12 at the rearmost side and the front side edge of the first air outlet. The rotation axis of the rearmost second air deflector 22 is located at the rear side edge of the second air outlet, or the distance between the rotation axis of the rearmost second air deflector 22 and the rear side edge of the second air outlet is smaller than the distance between the rearmost second air deflector 22 and the front side edge of the second air outlet, and the number of the second air deflector 22 is one. Preferably, the number of first air deflectors 12 is two. The number of the second air deflectors 22 is one.
In some embodiments of the present invention, the lower end or the upper end of the second air outlet column 20 is rotatably disposed around a horizontal axis, and the horizontal axis is perpendicular to the plane of the first air outlet 11, 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.
Further, the indoor unit of the air conditioner further comprises a plurality of temperature sensors, the temperature sensors are sequentially arranged at the first air outlet 11 along the vertical direction, so as to detect the air outlet temperature of the first air outlet 11 along a plurality of positions, and further enable the second air outlet column 20 to rotate to the front side of the area, corresponding to the corresponding air outlet temperature, of the first air outlet 11 according to the air outlet temperature. Specifically, the first air outlet 11 is divided into six areas, 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, the air flow out of the first air outlet 11 and the air flow out of the second air outlet 21 may be mixed when the second air outlet is at the initial position. The air flow flowing out of the second air outlet 21 can be non-heat exchange air flow, the air flow flowing out of the first air outlet 11 and the air flow flowing out of the second air outlet 21 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 air quantity and the wind speed are increased, the air supply distance is farther, and the air flow flowing out of the second air outlet 21 can be better diffused to all places in a room.
In some embodiments of the present invention, as shown in fig. 1, when the second air outlet post is at the initial position, an air guiding space 16 is formed between the second air outlet post 20 and the first air outlet post 10, so that when the first air outlet 11 and/or the second air outlet 21 are/is air-out, air in the air guiding space 16 is driven to flow forward by virtue 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.
