This is merely to facilitate description of the invention and to simplify the description, and is not intended to indicate or imply that the device or element so referred to must be in a particular orientation, constructed and operated in a particular orientation, and thus should not be taken as limiting the invention.
Referring to fig. 1 to 3, fig. 1 is a schematic view of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention, fig. 2 is a sectional view of the indoor unit according to a first embodiment of the present invention when a louver is in an up-blowing position, fig. 3 is a sectional view of the indoor unit according to the first embodiment of the present invention when the louver is in a down-blowing position, and arrows in the drawings show a direction of an air flow.
The invention provides a wall-mounted air conditioner indoor unit 1, and the wall-mounted air conditioner indoor unit 1 can comprise components such as a shell 10, an air duct 14, a heat exchanger 20, a heat exchange fan 30 and the like.
The casing 10 serves as a casing of the indoor unit 1, and protects the entire indoor unit 1, and at least one air inlet 12 and at least one air outlet 13 are further provided on the casing 10.
The inside of the casing 10 may further define a heat exchanging space 16, the heat exchanging space 16 is used for installing a heat exchanger 20 and a heat exchanging fan 30, under the urging of the heat exchanging fan 30, indoor air may enter the heat exchanging space 16 from the air inlet 12, and exchange heat with the heat exchanger 20, and finally be discharged into a room from the air outlet 13, so as to adjust the indoor temperature.
The air duct 14 may be disposed in the heat exchanging space 16, and an inlet end of the air duct faces an air outlet end of the heat exchanging fan 30, and an outlet end of the air duct 14 may be connected to the air outlet 13 to guide the supply airflow to the air outlet 13.
In some embodiments, the wall-mounted air conditioning indoor unit 1 may further include a wind deflector 40, where the wind deflector 40 is rotatably installed at the wind outlet 13, and the wind deflector 40 has a first flow guiding surface 41 and a second flow guiding surface 42 extending in different directions.
Referring to fig. 2, in the present embodiment, the air deflector 40 may be rotatably disposed at the air outlet 13, and can rotate to an upward blowing position where the extending direction of the first guiding surface 41 is upward, so that the air flow discharged from the outlet of the air duct 14 can be discharged upward by the first guiding surface 41.
Referring to fig. 3, because the extending directions of the first flow guiding surface 41 and the second flow guiding surface 42 are different, the air deflector 40 of the present embodiment can also rotate to make the extending direction of the second flow guiding surface 42 be at the downward blowing position, and when the blowing air flow discharged from the outlet of the air duct 14 can be discharged downward under the action of the second flow guiding surface 42.
It should be noted that the above-mentioned "upward" and "downward" should be understood as giving the blowing air flow a tendency to be discharged upward and downward. That is, when the air deflector 40 is in the upward blowing position, the first flow guiding surface 41 may extend vertically upward, or may extend forward and upward; when the air deflector 40 is in the down-blowing position, the second deflector surface 42 extends vertically downward, and may also extend forward downward.
As is well known, in the use of the air conditioner, since the density of the hot air is relatively low compared to that of the cold air, this may cause a defect that the hot air of the indoor unit 1 cannot reach the ground in the heating mode, while the cold air is blown down to the user in the cooling mode.
In order to overcome the above-mentioned defects, in the prior art, an air deflector is rotatably disposed at one side of an air supply outlet of an air conditioner to guide air flow of supply air. The above-described adjustment methods have certain drawbacks. Because the air deflector is rotatably arranged on one side of the air supply opening, the rotation angle of the air deflector is limited, and cold air or hot air is difficult to reach a roof or a floor area, thereby influencing the refrigeration or heating effect.
In order to overcome the above-mentioned drawbacks of the prior art, in the wall-mounted air conditioning indoor unit 1 of the present embodiment, the air deflector 40 is disposed as the first guiding surface 41 and the second guiding surface 42 with different extending directions, and the air deflector 40 can rotate around the air outlet 13 at a full angle, so as to guide the supply air upwards when the air deflector 40 is at the upward blowing position, and guide the supply air downwards when the air deflector 40 is at the downward blowing position, which is no longer limited by the rotation angle of the air deflector 40.
Referring to fig. 2, for example, in the cooling mode, the user may adjust the air deflector 40 to be in the upward blowing position, where the first flow guiding surface 41 of the air deflector 40 is in the upward extending direction, and at this time, the cold air may be discharged upward along the first flow guiding surface 41, so that the cold air discharged from the outlet of the air duct 14 is prevented from directly blowing the user due to the high density.
Referring to fig. 3, in the heating mode, the user may adjust the air deflector 40 to be in the downward blowing position, in which the second guiding surface 42 of the air deflector 40 is in the downward extending direction, and in which the hot air may be discharged downward along the second guiding surface 42 to forcibly guide the hot air to the ground, so as to prevent the hot air discharged from the outlet of the air duct 14 from being discharged upward due to low density.
It should be noted that the above example is only for describing the operation principle of the air deflector 40 of the present embodiment more clearly, and is not used to limit the temperature adjusting mode (cooling or cooling) of the indoor unit 1 when the air deflector 40 is at any position. The user can adjust the position of the air guiding plate 40 at will according to actual situations, for example, adjust the air guiding plate 40 to the up-blowing position in the heating mode, and so on, which will not be described herein.
Referring to fig. 2 and 3, in some embodiments, the air deflection panel 40 may further include a first panel segment 43 and a second panel segment 44.
The first plate section 43 may extend along a transverse direction of the air outlet 13, the second plate section 44 may extend perpendicularly from one end of the first plate section 43 in a width direction, and the first flow guiding surface 41 and the second flow guiding surface 42 are surfaces of the first plate section 43 and the second plate section 44 facing each other, respectively.
In this embodiment, the first plate section 43 is perpendicular to the second plate section 44, the first flow guiding surface 41 is formed on the inner side of the first plate section 43, and the second flow guiding surface 42 is formed on the inner side of the second plate section 44. Because the first guiding surface 41 guides the supply air flow when the air deflector 40 is at the upward blowing position and the second guiding surface 42 guides the supply air flow when the air deflector 40 is at the downward blowing position, the inner side surface of the air deflector 40 always faces the outlet of the air duct 14 when the air deflector 40 is at the upward blowing position and the downward blowing position, so as to guide the supply air flow upward and downward.
Referring to fig. 4 and 5, fig. 4 is a sectional view of an indoor unit according to a second embodiment of the present invention when a air guide plate is in an up-blowing position, and fig. 5 is a sectional view of an indoor unit according to a second embodiment of the present invention when the air guide plate is in a down-blowing position, in which arrows indicate the direction of air flow.
In other embodiments, the included angle between the first plate section 43 and the second plate section 44 of the air deflector 40 can also be configured to be an obtuse angle.
When the air deflector 40 is in the up-blowing position, the first guiding surface 41 guides the supply air flow, and when the air deflector 40 is in the down-blowing position, the second guiding surface 42 guides the supply air flow, and the air deflector 40 of the embodiment can also achieve the technical effects.
Referring to fig. 2 and 3, in some embodiments, the bottom wall 14b of the air duct 14 is located above the bottom wall 10a of the casing 10, the front end of the top wall 14a of the air duct 14 is located above and in front of the front end of the bottom wall 14b, and the rotating shaft 45 of the air deflector 40 is located at the midpoint between the front end of the top wall 14a of the air duct 14 and the front end of the bottom wall 10a of the casing 10.
In this embodiment, the air outlet 13 may be disposed below the casing 10 and face to the front lower direction. The air deflector 40 may further include connection plates (not shown) disposed at two sides of the air outlet 13, and the rotation shaft 45 of the air deflector 40 is transversely disposed at the air outlet 13 and rotatably connected to the air outlet 13, so that the air deflector 40 is rotatably disposed at the air outlet 13.
Referring to fig. 2 and 3, in some embodiments, the distance between the rotational axis 45 of the air deflector 40 and the top wall 14a of the air chute 14 is equal to the distance between the rotational axis 45 of the air deflector 40 and the first plate section 43.
Referring to fig. 2, the air deflector 40 may be further configured such that when it is in the upward blowing position, the end of the second plate section 44 is connected to the front end of the bottom wall 14b of the air duct 14, and the first plate section 43 extends forward and upward.
Referring to fig. 3, the air deflector 40 may also be configured such that when it is in the down-blowing position, the second plate segment 44 is horizontally abutted against the top wall 14a of the air chute 14, and the second plate segment 44 extends vertically downward.
In the present embodiment, the widths of the first plate section 43 and the second plate section 44 may be configured to be the same, and the rotating shaft 45 of the air deflector 40 may be disposed at the inner side of the first plate section 43 and the second plate section 44 facing each other.
Referring to fig. 2, the width of the second plate section 44 may also be configured such that when the air deflector 40 is in the upward blowing position, the end of the second plate section 44 just abuts against the front end of the bottom wall 14b of the air duct 14 to seal the gap between the air deflector 40 and the bottom wall 14b of the air duct 14, so that the blowing air cannot be discharged from the gap between the air deflector 40 and the bottom wall 14b of the air duct 14, but is completely discharged upward under the guidance of the first plate section 43.
Referring to fig. 2, since the bottom wall 14b of the air duct 14 is located above the bottom wall 10a of the casing 10, the front end of the top wall 14a of the air duct 14 is located above the front end of the bottom wall 14b, the rotating shaft 45 of the air deflector 40 is located at the midpoint between the top wall 14a of the air duct 14 and the front end of the bottom wall 10a of the casing 10, and the first plate section 43 and the second plate section 44 are perpendicular, when the air deflector 40 is in the upward blowing position, when the end of the second plate section 44 abuts against the front end of the bottom wall 14b of the air duct 14, the first plate section 43 extends forward and upward to guide the blowing air flow forward and upward.
Referring to fig. 3, since the distance between the rotation axis 45 of the air deflector 40 and the top wall 14a of the air duct 14 is equal to the distance between the rotation axis 45 of the air deflector 40 and the first plate section 43, and the first plate section 43 and the second plate section 44 are perpendicular to each other, when the air deflector 40 is in the down-blowing position, the first plate section 43 can horizontally abut against the lower side of the top wall 14a of the air duct 14, and the second plate section 44 vertically extends downward.
Thus, when the air deflector 40 is in the downward blowing position, the first plate section 43 horizontally abuts against the lower side of the top wall 14a of the air duct 14, so that the gap between the air deflector 40 and the top wall 14a of the air duct 14 can be sealed, and the air supply flow cannot be discharged from the gap between the first plate section 43 and the top wall 14a of the air duct 14, but is completely discharged downward under the guidance of the second plate section 44.
Referring to fig. 6, fig. 6 is a cross-sectional view of an indoor unit according to a third embodiment of the present invention, in which an air deflector is in an upward blowing position, and an arrow shows the direction of air flow.
In some alternative embodiments, the bottom wall 14b of the air duct 14 is located above the bottom wall 10a of the casing 10, and the front end of the top wall 14a of the air duct 14 may also be configured to be located right above the front end of the bottom wall 14b of the air duct 14.
That is, in this embodiment, the air outlet 13 may be disposed toward the direction, and the air deflector 40 may be disposed outside the cabinet 10. When the air guiding plate 40 is in the upward blowing position, the end of the second plate section 44 may directly abut against the front end of the bottom wall 10a of the casing 10, and the first plate section 43 extends vertically upward. When the air deflector 40 is in the down-blowing position, the first plate section 43 is in a horizontal state with its end abutting against the front end of the top wall 14a of the wind tunnel 14, and the second plate section 44 extends vertically downward.
Referring to fig. 7, fig. 7 is a sectional view of an indoor unit according to a first embodiment of the present invention, wherein an air deflector is in a closed position.
In some embodiments, the air deflector 40 can be further configured to rotate to a closed position in which the end of the first plate section 43 is connected to the front end of the top wall 14a of the air duct 14 and the end of the second plate section 44 is connected to the front end of the bottom wall 10a of the cabinet 10, so as to close the air outlet 13. That is, the air guide plate 40 can not only guide the air flow upward or downward, but also close the outlet 13.
Further, when the air deflector 40 is in the closed position, the front wall 10b of the casing 10 is flush with the first plate section 43, and the bottom wall 10a of the casing 10 is flush with the second plate section 44, so that when the air deflector 40 is in the closed position, the sealing performance is better and the appearance of the indoor unit 1 is neat and beautiful.
Referring to fig. 8, fig. 8 is a cross-sectional view of an indoor unit according to a first embodiment of the present invention, wherein an air deflector is in a first air-splitting position, and an arrow indicates a direction of an air flow.
In some embodiments, the air deflector 40 further has a third flow guide surface 46, and the third flow guide surface 46 may be formed by a surface of the first plate segment 43 facing away from the first flow guide surface 41 and a surface of the second plate segment 44 facing away from the second flow guide surface 42.
The casing 10 is provided with an upper duct 18 penetrating through a front wall 10b of the casing 10 and a top wall 14a of the duct 14, and the upper duct 18 extends upward and forward.
The air deflector 40 is further configured to rotate to a first air dividing position where the third air guiding surface 46 faces the air duct 14 and the second plate section 44 extends toward the upper air duct 18, so that an air supply gap is formed between the first plate section 43 and the bottom wall 14b of the air duct 14, and the third air guiding surface 46 is used to discharge the air supply flow out of the air duct 14 from the air supply gap and the upper air duct 18.
In the present embodiment, since the first plate section 43 and the second plate section 44 extend in different directions, when the air deflector 40 rotates to make the third guiding surface 46 face the air duct 14, the third guiding surface 46 of the air deflector 40 is in a state of diverging upward and downward as viewed in the flow direction of the supply air flow, and therefore the third guiding surface 46 can guide the supply air flow at the outlet end of the air duct 14 upward and downward at the same time.
Specifically, when the air deflector 40 is located at the first air dividing position, the second plate section 44 extends toward the upper air duct 18, the end portion of the second plate section can abut against the bottom wall of the upper air duct 18, an air supply gap is formed between the first plate section 43 and the bottom wall 14b of the air duct 14, and air flow discharged from the outlet end of the air duct 14 can be discharged out of the air duct 14 from the air supply gap and the upper air duct 18, so that the air flow is dispersed, the air flow is blown into the room more softly, and the experience of a user is improved.

The first arc surface 14d and the second arc surface 10c are configured such that when the air deflector 40 is rotated, the end of the air deflector 40 slides in contact with the first arc surface 14d and the second arc surface 10 c.
Specifically, the first arc surface 14d and the second arc surface 10c may be arcs centered on the rotation axis 45 of the air deflector 40.
Since the distance between the rotating shaft 45 of the air deflector 40 and the top wall 14a of the air duct 14 is equal to the distance between the rotating shaft 45 of the air deflector 40 and the first plate section 43, the first arc surface 14d may be recessed upward to allow the end of the air deflector 40 to pass through.
Because the bottom wall 14b of the air duct 14 is located above the bottom wall 14b of the casing 10, the front end of the top wall 14a of the air duct 14 is located above the front end of the bottom wall 14b, and the rotating shaft 45 of the air deflector 40 is located at the midpoint between the top wall 14a of the air duct 14 and the front end of the bottom wall 10a of the casing 10, the front end of the bottom wall 14b of the air duct 14 and the front end of the bottom wall 10a of the casing 10 are both located on an arc centered on the rotating shaft 45 of the air deflector 40, and the second arc surface 10c connected to the front end of the bottom wall 14b of the air duct 14 and the front end of the bottom wall 14b of the casing 10 is recessed backwards to allow the end of the air deflector 40 to pass through.
Referring to fig. 9 and 10, fig. 9 is a sectional view of an indoor unit according to a fourth embodiment of the present invention, in which an arrow indicates a direction of an air current, when a louver is in a second air dividing position, and fig. 10 is a sectional view of an indoor unit according to yet another embodiment of the present invention, when the louver is in a closed position.
In other embodiments, the distance between the rotational axis 45 of the air deflector 40 and the top wall 14a of the air chute 14 may also be configured to be greater than the distance between the rotational axis 45 and the second plate section 44.
The air deflector 40 can also be configured to rotate to a second air distribution position where the first air guide surface 41 and the second air guide surface 42 are away from the air duct 14 at the same time, and the second plate section 44 is parallel to the top wall 14a of the air duct 14, a gap is formed between the first plate section 43 and the bottom wall 14b of the air duct 14, at least one part of the air supply flow can be horizontally guided and discharged by the surface away from the second air guide surface 42, and the other part of the air supply flow can be guided and discharged downwards by the gap, so that the air supply flow is dispersed, the air supply flow is blown into the room more softly, and the experience of a user is improved.
Further, the indoor unit 1 may further include a sealing flap 50, and the sealing flap 50 is movably disposed at the bottom wall 10a of the casing 10 and used for closing the air outlet 13 when the air deflector 40 is in the second air distribution position.
The sealing baffle 50 may be hinged to the bottom wall 10a of the cabinet 10, and since a gap is formed between the first plate section 43 and the bottom wall 14b of the air duct 14 and a gap is formed between the second plate section 44 and the top wall 14a of the air duct 14 when the air deflector 40 is in the second air distribution position, the sealing baffle 50 for sealing the air outlet 13 is added to the indoor unit 1 of the present embodiment, so as to close the air outlet 13 when the air deflector 40 is in the second air distribution position.
In the wall-mounted air conditioning indoor unit 1 of the present invention, the air deflector 40 has the first guide surface 41 and the second guide surface 42 with different extending directions, and the air deflector 40 is rotatably installed at the air outlet 13, and the air deflector 40 rotates to be at the upward blowing position, at which the air deflector 40 guides the supply air flow upward by using the first guide surface 41, and rotates to be at the downward blowing position, at which the air deflector 40 guides the supply air flow downward by using the second guide surface 42, so that the adjustment angle of the air deflector 40 is larger, and the supply air amount is not affected.
Furthermore, in the wall-mounted air conditioning indoor unit 1 of the present invention, the air deflector 40 has the first flow guiding surface 41 and the second flow guiding surface 42 with different extending directions, the air deflector 40 further has the third flow guiding surface 46, the third flow guiding surface 46 can be formed by surfaces of the first plate section 43 departing from the first flow guiding surface 41 and the second plate section 44 departing from the second flow guiding surface 42, the upper duct 18 penetrating through the front wall 10b of the casing 10 and the top wall 14a of the duct 14 is formed on the casing 10, the upper duct 18 extends forward and upward, when the air deflector 40 is located at the first air dividing position, the third flow guiding surface 46 faces the duct 14, the second plate section 44 extends toward the upper duct 18, an air supply gap is formed between the first plate section 43 and the bottom wall 14b of the duct 14, and the third flow guiding surface 46 is further utilized to discharge the air supply from the air supply gap and the upper duct 18 respectively, so as to disperse the air supply, so that the air flow is more softly blown into the room, and the experience of the user is improved.
