Fig. 1 is a schematic structural view of a closed air guide 50 and an air guide plate 60 of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, as shown in fig. 1, and referring to fig. 2 to 17, an embodiment of the present invention provides a wall-mounted air conditioner indoor unit, which includes a housing 10 and an air guide 50. The housing 10 has an air outlet 40 facing forward and downward, and in the above figures, the position of the dotted line is the position of the air outlet 40. The housing 10 defines an accommodating space for accommodating components of the wall-mounted air conditioner indoor unit. The air flow in the housing 10 is discharged to the indoor environment to condition the indoor air. The discharged air flow refers to an air flow for adjusting indoor environments, such as cool air in a cooling mode, hot air in a heating mode, and fresh air in a fresh air mode, etc., which is acted on by the blower 30 in the case 10 to accelerate the air flow through the air outlet. The housing 10 may be an elongated shape with a horizontal longitudinal direction, and the air outlet 40 may be an elongated shape with a longitudinal direction parallel to the longitudinal direction of the housing 10. The upper edge of the air outlet 40 is located forward and upward of the lower edge of the air outlet 40. The upper edge of the air outlet 40 is located on the front surface of the housing 10 such that the front surface of the housing 10 has an air guiding region extending upward from the upper edge of the air outlet 40.

As shown in fig. 2, the air guide body 50 has a first air guide surface 501 and a second air guide surface 502. The first air guiding surface 501 and the second air guiding surface 502 are connected, the first air guiding surface 501 has a first edge and a second edge, the first edge is located above the front of the second edge, and the second air guiding surface 502 extends vertically downward, forward and downward, or backward and downward from the second edge of the first air guiding surface 501. The first edge of the first air guiding surface 501 is located above the front of the upper edge of the air outlet 40, the first air guiding surface 501 is arranged at intervals with the upper edge of the air outlet 40, and the first air guiding surface 501 is arranged at intervals with the air guiding area to form an upper air duct. The lower edge of the second air guiding surface 502 is located right in front of, above or below the lower edge of the air outlet 40, and the second air guiding surface 502 is spaced from the lower edge of the air outlet 40 to form a lower air duct.

The first air guiding surface 501 and the second air guiding surface 502 guide the air flow flowing out from the air outlet 40 into the space between the first air guiding surface 501 and the air guiding area and the space between the second air guiding surface 502 and the lower edge of the air outlet 40.

That is, the lower end of the first air guiding surface 501 is located in the air outlet range of the air outlet 40, so as to divide the air flow flowing out from the air outlet 40 into two parts, wherein one part of the air flow flows out from the space between the first air guiding surface 501 and the air guiding area, and the other part of the air flow flows out from the space between the second air guiding surface 502 and the lower edge of the air outlet 40. The first air guiding surface 501 is inclined forward and upward, and the first air guiding surface 501 and the air guiding region may guide the air flow flowing through the space between the first air guiding surface 501 and the air guiding region forward and upward. The second air guiding surface 502 and the lower edge of the air outlet 40 may guide the air flowing from the space between the second air guiding surface 502 and the lower edge of the air outlet 40 downward, and in this specification, downward may refer to downward, forward downward, or backward downward.

In this embodiment, the air guide body 50 is arranged to significantly increase the air outlet angle of the indoor unit of the wall-mounted air conditioner, so that the air flow is blown out from the front upper side and the front lower side, the air flow is prevented from directly facing the user, and the comfort level of the user is improved.

Further, the upper edge of the second air guiding surface 502, i.e. the second edge of the first air guiding surface, is located under, under or behind the upper edge of the air outlet 40, and the upper edge of the second air guiding surface 502 is located above and in front of the lower edge of the air outlet 40. At this time, the upper edge of the second air deflector 60 is located in front of the air outlet 40, and this arrangement ensures that the lower end of the first air guiding surface 501 is located in the air outlet range of the air outlet 40, so that the air flow flowing out from the air outlet 40 can be more conveniently divided into two parts.

In some embodiments of the present invention, wind-guiding body 50 is movably disposed such that when wind-guiding body 50 is in at least two positions of movement:

the first edge is located forward and above the second edge, and the second air guiding surface 502 extends vertically downward, forward and downward, or rearward and downward from the second edge of the first air guiding surface 501. The first edge of the first air guiding surface 501 is located above the front of the upper edge of the air outlet 40, the first air guiding surface 501 is arranged at intervals with the upper edge of the air outlet 40, and the first air guiding surface 501 is arranged at intervals with the air guiding area. The upper edge of the second air guiding surface 502 is located below the upper edge of the air outlet 40, the upper edge of the second air guiding surface 502 is located above the lower edge of the air outlet 40, the lower edge of the second air guiding surface 502 is located right in front of, above or below the lower edge of the air outlet 40, and the second air guiding surface 502 and the lower edge of the air outlet 40 are arranged at intervals. It should be noted here that the movement position is a position that can be moved to, where it does not have to stay, but can be understood as a position in the area through which the wind passes. Of course, the stay may also be performed at this position.

In these embodiments, the air guiding body 50 is movably disposed, and the air guiding body 50 can adjust the size of the interval between the first air guiding surface 501 and the air guiding area and the interval between the second air guiding surface 502 and the lower edge of the air outlet 40 while dividing the air flow flowing out from the air outlet 40. For example, when the wall-mounted air conditioner indoor unit blows cold air, the air guide body 50 moves to enable the interval between the first air guide surface 501 and the air guide area to be remarkably increased, the interval between the second air guide surface 502 and the lower edge of the air outlet 40 to be remarkably reduced, and therefore most of cold air flows to the front upper side of the wall-mounted air conditioner indoor unit to be blown out, and the refrigerating effect is better. When the wall-mounted air conditioner indoor unit blows hot air, the air guide body 50 moves to enable the interval between the first air guide surface 501 and the air guide area to be obviously reduced, and the interval between the second air guide surface 502 and the lower edge of the air outlet 40 is obviously increased, so that most of hot air flows to the lower side of the wall-mounted air conditioner indoor unit to be blown out, and the heating effect is better. The position where the wind guide 50 moves such that the first edge is at the highest position may be an initial position of the wind guide 50.

Further, when the wall-mounted air conditioning chamber may be provided with hot air blowing, the air guide body 50 moves to a position where the first edge is at the highest position, that is, when the first edge is at the highest position, the first air guide surface 501 contacts with the air guide area at least one position to prevent hot air from the air outlet 40 from flowing out from the interval between the first air guide surface 501 and the air guide area, that is, all hot air flows out downwards from the interval between the second air guide surface 502 and the lower edge of the air outlet 40, so that the heating effect is more obvious.

Further, as shown in fig. 4, when the wall-mounted air conditioning chamber is configured to blow hot air, the air guide body 50 moves to a position where the first edge is at the highest position, that is, when the first edge is at the highest position, the first air guide surface 501 is attached to the air guide area. The second edge is located right below or behind the upper edge of the air outlet 40, and the second air guiding surface may be vertically disposed. In the above arrangement, no wind enters between the first wind guiding surface 501 and the wind guiding area, and the wind guiding body 50 is more stable.

In some embodiments of the invention, first air guiding surface 501 and second air guiding surface 502 are both planar. Thereby making the air flow through the first air guiding surface 501 and the second air guiding surface 502 smoother. Of course, in some other embodiments of the present invention, the first air guiding surface 501 and the second air guiding surface 502 may be configured as cambered surfaces at the same time or alternatively.

As shown in fig. 5, in some embodiments of the present invention, the first air guiding surface 501 and the second air guiding surface 502 form an included angle B between 120 ° and 180 °, which is more beneficial to expanding the air outlet angle of the wall-mounted air conditioner indoor unit. Further, the second edge of the first wind guiding surface 501 is rounded, that is, the first wind guiding surface 501 and the second wind guiding surface 502 are connected by rounded corners, so that the transition between the first wind guiding surface 501 and the second wind guiding surface 502 is more gentle, the flowing resistance of the air flow is smaller, and the wind guiding effect of the wind guiding body 50 is better.

In some embodiments of the present invention, the air guiding region includes a third air guiding surface 101 extending upward from an upper edge of the air outlet 40, and an air duct for forward and upward air outlet is formed between the third air guiding surface 101 and the first air guiding surface 501. The third air guiding surface 101 is a plane, so that the air flowing through the third air guiding surface 101 flows out smoothly. Of course, in other embodiments of the present invention, the third air guiding surface 101 may be a cambered surface.

Further, the air guiding area further includes a fourth air guiding surface 102 extending forward or forward and upward from the upper edge of the third air guiding surface 101, and the fourth air guiding surface 102 is used for guiding the forward and upward air outlet to the forward and upward air outlet. The fourth air guiding surface 102 is a plane or the fourth air guiding surface 102 is a cambered surface.

In some embodiments of the invention, as shown in fig. 5, the enclosure has a duct therein defined by upper and lower duct walls spaced apart from one another. The outlet ends of the upper duct wall and the lower duct wall are the upper edge and the lower edge of the air outlet 40, respectively, for guiding the air flow in the cabinet to the air outlet 40. An air inlet 70 is formed in the top of the machine shell, and a cross-flow fan 30 with an axis extending along the transverse direction is arranged in the air duct. The three-stage heat exchanger 20 surrounds the upper side of the cross flow fan 30. When the wall-mounted air conditioner indoor unit operates in a refrigerating mode or a heating mode, indoor air enters the interior of the machine shell through the air inlet 70, exchanges heat with the three-stage heat exchanger 20, is finally sucked into the air channel by the cross-flow fan 30, and flows to the air outlet 40.

The upper duct wall includes an interconnecting volute tongue section 105 and a first air outlet section 106. The first air outlet section 106 extends forward and downward from the volute tongue section 105 to the upper edge of the air outlet 40. The first air outlet section 106 is a plane, an included angle A between the first air outlet section 106 and the third air guiding surface 101 is between 80 degrees and 100 degrees, and an included angle between the third air guiding surface 101 and the horizontal plane is between 40 degrees and 60 degrees. Further, the upper edge of the air outlet is provided with a round corner, so that the air flow is lifted and blown out.

The lower duct wall comprises a volute section 103 and a second air outlet section 104. The volute section 103 arches rearward with its upper end constituting the inlet end of the rear duct wall. The second air outlet section 104 extends obliquely forward and downward from the volute section 103 to the lower edge of the air outlet 40. The second air outlet section 104 is a plane.

In some embodiments of the present invention, when moving, wind-guiding body 50 moves the first edge downward or forward downward from its highest position, and moves the lower edge of second wind-guiding surface 502 downward or rearward downward from its highest position.

In some embodiments of the present invention, as shown in fig. 7, the wind guide 50 is rotatably disposed on the housing 10. Further, the wind guiding body 50 rotates around a lateral axis 107 provided on the casing 10, and the lateral axis 107 is provided at the lower edge of the wind outlet 40. The lower edge of the second wind guiding surface 502 may be fixedly connected to the lateral axis 107, so that the wind guiding body 50 rotates downward.

As shown in fig. 6, when the wind guiding body 50 rotates downward from the highest position to a preset position, the interval between the first wind guiding surface 501 and the wind guiding area is gradually expanded, and the ratio of the linear distance L2 between the first wind guiding surface 501 and the forefront of the wind guiding area to the linear distance L1 between the first wind guiding surface 501 and the upper edge of the air outlet 40 is between 1.8 and 2.2. When the wall-mounted air conditioner indoor unit blows cold air, the upper cold air blowing speed is lower, and when the cold air shower type sedimentation is carried out, the cold air speed is more moderate and the user feels comfortable.

In some alternative embodiments of the present invention, as shown in fig. 16 and 17, the wind guiding body 50 is vertically slidably disposed on the housing 10, and the wind guiding body 50 is vertically moved by the driving device and the transmission device 110. The driving device is a motor, and the transmission device 110 is a meshed gear rack.

In some embodiments of the present invention, the wall-mounted air conditioner indoor unit further includes an air deflector 60. The air deflector 60 is rotatably disposed between the second air guiding surface 502 and the lower edge of the air outlet 40, the air deflector 60 can open the space between the second air guiding surface 502 and the lower edge of the air outlet 40, and the air deflector 60 can also close the space between the second air guiding surface 502 and the lower edge of the air outlet 40 at a specific position. For example, the air deflector 60 and the second air outlet section 104 may be located on the same plane, while closing the space between the second air guiding surface 502 and the lower edge of the air outlet 40. When the wall-mounted air conditioner indoor unit blows cold air, all cold air flows out from the front upper side of the interval between the first air guide surface 501 and the air guide area, and the situation that the cold air blows people directly is avoided. The air deflector 60 may also be used to divide the air flow, directing the air flow exiting the air outlet into the space between the first air guiding surface 501 and the air guiding region and the space between the second air guiding surface 502 and the lower edge of the air outlet. The air deflector 60 is rotatably provided around the front end thereof, and when the air is heated, the air deflector 60 can be rotated to a vertical position so that all the hot air is blown downward.

In the initial position of the air guide body 50 and the air guide plate 60, the air guide plate 60 is arranged between the lower edge of the second air guide surface 502 and the lower edge of the air outlet, and the air guide plate 60 is obliquely arranged at the front lower side and the rear higher side, but the air guide plate 60 can also be obliquely arranged.

In some embodiments of the present invention, the baffle 80 is fixedly disposed between the lower edge of the air outlet 40 and the second air guiding surface 502. For example, in the initial position of the air guiding body, the baffle 80 is fixedly disposed between the lower edge of the air outlet 40 and the lower edge of the second air guiding surface 502. The rear edge of the baffle 80 is fixedly connected with the lower edge of the air outlet 40. The baffle 80 is provided with micro-holes. The baffle 80 fixed to the lower edge of the air outlet 40 and the second air guiding surface 502 is provided with micro holes, and the micro holes are vertically arranged to make the air passing through the micro holes blow out vertically downwards. Of course, in some alternative embodiments, the micropores may also be oriented perpendicular to the surface of the baffle 80. In this embodiment, the air deflection 60 may not be present, and if the air deflection 60 is provided, the air deflection 60 may be above the baffle 80.

In some embodiments of the invention, the baffle 80 may be a horizontally disposed flat plate; or the baffle 80 is a flat plate, and the baffle is obliquely arranged and is positioned on the same plane with the second air outlet section. Of course, the baffle 80 may be in other shapes, for example, the cross-sectional profile of the baffle 80 is triangular, the upper surface of the baffle 80 and the second air outlet section 104 are located on the same plane, the lower surface of the baffle 80 is horizontally arranged, and the triangular profile can guide the air flow flowing out from the lower edge of the air outlet 40 to flow downwards and forwards, so that the baffle 80 has the function of guiding the air direction.

In some embodiments of the present invention, the lower edge of the air outlet 40 extends downward to form an air guiding wall, and the included angle C between the second air guiding surface 502 and the horizontal plane is between 70 ° and 110 °, and the air guiding wall is spaced from the second air guiding surface 502. A lower air duct for downward air flow is formed between the air guide wall and the second air guide surface 502, and the air flow passing through the lower air duct is blown downward. The lower edge of the air outlet is provided with a round corner.

In some embodiments of the present invention, the air deflector 60 is rotatably disposed in a space between the second air guiding surface 502 and the lower edge of the air guiding wall, and the air deflector 60 has a function of guiding and dividing air in addition to a function of opening or closing the space between the second air guiding surface 502 and the air guiding wall. When the air guide plate 60 is directed toward the air outlet 40 at a side edge away from the rotational axis 108, the side edge enters the air outlet 40, thereby dividing the air flow from the air outlet 40 into the air flow flowing out from one side surface of the air guide plate 60 and the air flow flowing out from the other side surface of the air guide plate 60. The two air flows enter the corresponding space between the first air guiding surface 501 and the air guiding area and the corresponding space between the second air guiding surface 502 and the air guiding wall respectively, and are blown out. And at the initial positions of the air guide body and the air guide plate, the air guide plate is arranged at the lower edge of the second air guide surface and the lower edge of the air guide wall, and the air guide plate is horizontally arranged.

In some embodiments of the present invention, the wall-mounted air conditioner indoor unit further includes a baffle 80, where the baffle 80 is disposed between the lower edge of the air guiding wall and the second air guiding surface 502, for example, in the initial position of the air guiding body, the baffle 80 is fixedly disposed between the lower edge of the air guiding wall and the lower edge of the second air guiding surface 502. One edge of the baffle 80 is fixedly connected with the lower edge of the air guide wall. The baffle 80 is provided with micro-holes. The downward air flow is blown out after being scattered by the micropores, and the air outlet is softer. The baffle 80 realizes downward air outlet, and meanwhile, the cost is lower, the failure is not easy to happen, and the appearance is attractive. In this embodiment, the air deflection 60 may not be present, and if the air deflection 60 is provided, the air deflection 60 may be above the baffle 80.

Further, the baffle 80 may be a horizontally disposed flat plate. Of course, the baffle 80 may be in other shapes, for example, the cross-sectional profile of the baffle 80 is triangular, the upper surface of the baffle 80 and the second air outlet section 104 are located on the same plane, the lower surface of the baffle 80 is horizontally arranged, and the triangular profile can guide the air flow flowing out from the lower edge of the air outlet 40 to flow downwards and forwards, so that the baffle 80 has the function of guiding the air direction. The rear end of the lower surface of the baffle 80 is the lower edge of the air guiding wall.
