[0067] Figure 1 is a schematic structural view of the air guide body 50 and the air guide panel 60 of the wall-mounted air conditioner indoor unit according to one embodiment of the present application, as shown in Figure 1 , and with reference to Figures 2 to 17 , the embodiment of the present application provides a wall-mounted air conditioner indoor unit, which comprises a shell 10 and an air guide body 50. The shell 10 has an air outlet 40 facing the lower front direction. In the above figure, the position of the air outlet 40 is shown by a dashed line. The shell 10 defines a containing space for containing various components of the wall-mounted air conditioner indoor unit. The air flow in the shell 10 is discharged to the indoor environment to adjust the indoor air. The discharged air flow refers to the air flow for adjusting the indoor environment, such as the cold air in the cooling mode, the hot air in the heating mode, and the fresh air in the fresh air mode, which is accelerated by the fan 30 in the shell 10 to flow through the air outlet. The shell 10 can be in the shape of a long strip horizontally arranged in the length direction, and the air outlet 40 can be in the shape of a long strip parallel to the length direction of the shell 10. The upper edge of the air outlet 40 is in front 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 shell 10, so that the front surface of the shell 10 has an air guide area extending upward from the upper edge of the air outlet 40.

[0068] As shown in Figure 2As shown, the air guide body 50 has a first air guide surface 501 and a second air guide surface 502. The first air guide surface 501 and the second air guide surface 502 are connected, the first air guide surface 501 has a first edge and a second edge, the first edge is above the second edge, the second air guide surface 502 extends vertically downward from the second edge of the first air guide surface 501, extends forward and downward, or extends backward and downward. The first edge of the first air guide surface 501 is above the upper edge of the air outlet 40 in front, the first air guide surface 501 is spaced apart from the upper edge of the air outlet 40, and the first air guide surface 501 is spaced apart from the air guide area to form an upper air duct. The lower edge of the second air guide surface 502 is in front of, above or below the lower edge of the air outlet 40, and the second air guide surface 502 is spaced apart from the lower edge of the air outlet 40 to form a lower air duct.

[0069] The first air guide surface 501 and the second air guide surface 502 guide the airflow flowing out of the air outlet 40 into the space between the first air guide surface 501 and the air guide area and the space between the second air guide surface 502 and the lower edge of the air outlet 40.

[0070] That is, the lower end of the first air guide surface 501 is within the air outlet range of the air outlet 40, for dividing the airflow flowing out of the air outlet 40 into two parts, one part of the airflow flows out of the space between the first air guide surface 501 and the air guide area, and the other part of the airflow flows out of the space between the second air guide surface 502 and the lower edge of the air outlet 40. The first air guide surface 501 is inclined upward and forward, and the first air guide surface 501 and the air guide area can guide the airflow flowing through the space between the first air guide surface 501 and the air guide area to the upper front. The second air guide surface 502 and the lower edge of the air outlet 40 can guide the airflow flowing through the space between the second air guide surface 502 and the lower edge of the air outlet 40 to the lower side, which in this specification can refer to the directly lower side, the front lower side or the rear lower side.

[0071] In this embodiment, the arrangement of the air guide body 50 significantly increases the air outlet angle of the wall-mounted air conditioner indoor unit, so that the airflow is blown out from the upper front and the lower side, avoiding the airflow directly facing the user, and improving the comfort of the user.

[0072] Further, the upper edge of the second air guide surface 502, i.e. the second edge of the first air guide surface, is below, directly below or above the lower edge of the air outlet 40, and the upper edge of the second air guide surface 502 is above the lower edge of the air outlet 40. At this time, the upper edge of the second air guide plate 60 is located in front of the air outlet 40, and this arrangement can ensure that the lower end of the first air guide surface 501 is within the air outlet range of the air outlet 40, and is more convenient for dividing the airflow flowing out of the air outlet 40 into two parts.

[0073] In some embodiments of the present application, the air guide body 50 is movably arranged, and when the air guide body 50 is in at least two movement positions:

[0074] The first edge is above and in front of the second edge, and the second air guide surface 502 extends vertically downward from the second edge of the first air guide surface 501, extends forward and downward, or extends backward and downward. The first edge of the first air guide surface 501 is above and in front of the upper edge of the air outlet 40, and the first air guide surface 501 is spaced apart from the upper edge of the air outlet 40 and spaced apart from the air guide area. The upper edge of the second air guide surface 502 is below the upper edge of the air outlet 40, the upper edge of the second air guide surface 502 is above the lower edge of the air outlet 40, the lower edge of the second air guide surface 502 is directly in front of, above, or below the lower edge of the air outlet 40, and the second air guide surface 502 is spaced apart from the lower edge of the air outlet 40. It should be noted here that the movement position refers to a position that can be moved to, and it is not necessarily stopped at this position, and it can also be understood as a position in the area swept by the air. Of course, it can also be stopped at this position.

[0075] In these embodiments, the air guide body 50 is movably arranged, and the air guide body 50 can adjust the size of the interval between the first air guide surface 501 and the air guide area and the interval between the second air guide surface 502 and the lower edge of the air outlet 40 while dividing the airflow flowing out of the air outlet 40. For example, when the wall-mounted air conditioner indoor unit blows cold air, the air guide body 50 moves to significantly increase the interval between the first air guide surface 501 and the air guide area, and significantly reduce the interval between the second air guide surface 502 and the lower edge of the air outlet 40, so that most of the cold air flows to the upper front of the wall-mounted air conditioner indoor unit, and the cooling effect is better. When the wall-mounted air conditioner indoor unit blows hot air, the air guide body 50 moves to significantly reduce the interval between the first air guide surface 501 and the air guide area, and significantly increase the interval between the second air guide surface 502 and the lower edge of the air outlet 40, so that most of the hot air flows to the lower side of the wall-mounted air conditioner indoor unit, and the heating effect is better. The position where the air guide body 50 moves to make the first edge be at the highest position can be the initial position of the air guide body 50.

[0076] Further, the wall-mounted air conditioner can be arranged to blow hot air, and when the air guide body 50 moves to the 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 the air guide area at at least one position to hinder the hot air from the air outlet 40 flowing out of the interval between the first air guide surface 501 and the air guide area, that is, all the hot air flows downward from the interval between the second air guide surface 502 and the lower edge of the air outlet 40, and the heating effect is more obvious.

[0077] Further, as Figure 4As shown, the wall-mounted air conditioning room can be configured such that when hot air is blown, the air guide 50 moves to a position where the first edge is at its highest position. Specifically, when the first edge is at its highest position, the first air guide surface 501 abuts the air guide area. The second edge is positioned directly below or below the upper edge of the air outlet 40, and the second air guide surface can be positioned vertically. In this configuration, no wind can enter between the first air guide surface 501 and the air guide area, making the air guide 50 more stable.

[0078] In some embodiments of the present invention, the first air guide surface 501 and the second air guide surface 502 are both flat surfaces. This allows for smoother airflow through the first air guide surface 501 and the second air guide surface 502. Of course, in some other embodiments of the present invention, either the first air guide surface 501 or the second air guide surface 502 can be curved surfaces.

[0079] like Figure 5 As shown, in some embodiments of the present invention, the angle B formed by the first air guide surface 501 and the second air guide surface 502 is between 120° and 180°. This arrangement is more conducive to expanding the air outlet angle of the wall-mounted air conditioner indoor unit. Furthermore, the second edge of the first air guide surface 501 is rounded, that is, the first air guide surface 501 and the second air guide surface 502 are connected by a rounded corner, making the transition between the first air guide surface 501 and the second air guide surface 502 smoother, reducing the flow resistance of the airflow, and improving the air diversion effect of the air guide body 50.

[0080] In some embodiments of the present invention, the air guide area includes a third air guide surface 101 extending upward from the upper edge of the air outlet 40. A wind duct for discharging air forward and upward is formed between the third air guide surface 101 and the first air guide surface 501. The third air guide surface 101 is flat, ensuring smooth airflow through the third air guide surface 101. Of course, in other embodiments of the present invention, the third air guide surface 101 may also be a curved surface.

[0081] Furthermore, the wind guide area further includes a fourth wind guide surface 102 extending forward or forward and upward from the upper edge of the third wind guide surface 101. The fourth wind guide surface 102 is used to guide the wind flowing forward and upward to flow forward or forward and upward. The fourth wind guide surface 102 is a flat surface or a curved surface.

[0082] like Figure 5As shown, in some embodiments of the present application, the casing has an air duct defined by an upper air duct wall and a lower air duct wall spaced apart from each other. The outlet ends of the upper air duct wall and the lower air duct wall are the upper edge and the lower edge of the air outlet 40 respectively, for guiding the airflow in the casing to the air outlet 40. The top of the casing is provided with an air inlet 70, and a cross-flow fan 30 with an axis extending in the transverse direction is arranged in the air duct. The three-stage heat exchanger 20 is arranged above the cross-flow fan 30. When the wall-mounted air conditioner indoor unit operates in the cooling mode or the heating mode, indoor air enters the interior of the casing through the air inlet 70, exchanges heat with the three-stage heat exchanger 20, and is finally sucked into the air duct by the cross-flow fan 30 and flows to the air outlet 40.

[0083] The upper air duct wall comprises a volute tongue section 105 and a first air outlet section 106 connected to each other. The first air outlet section 106 extends from the volute tongue section 105 to the upper edge of the air outlet 40 in a forward and downward direction. The first air outlet section 106 is a plane, and the included angle A between the first air outlet section 106 and the third air guide surface 101 is between 80° and 100°, and the included angle between the third air guide surface 101 and the horizontal plane is between 40° and 60°. Further, the upper edge of the air outlet is provided with a rounded corner, which is beneficial for the upward blowing of the airflow.

[0084] The lower air duct wall comprises a volute section 103 and a second air outlet section 104. The volute section 103 is arched rearward, and its upper end constitutes the inlet end of the rear air duct wall. The second air outlet section 104 extends from the volute section 103 to the lower edge of the air outlet 40 in a forward and downward direction. The second air outlet section 104 is a plane.

[0085] In some embodiments of the present application, when the air guide body 50 moves, the first edge moves downward from its highest position or moves forward and downward, and the lower edge of the second air guide surface 502 moves downward from its highest position or moves rearward and downward.

[0086] In some embodiments of the present application, as shown, Figure 7 The air guide body 50 is rotatably arranged on the casing 10. Further, the air guide body 50 rotates around the transverse axis 107 arranged on the casing 10, and the transverse axis 107 is arranged at the lower edge of the air outlet 40. The lower edge of the second air guide surface 502 is fixedly connected to the transverse axis 107, so that the air guide body 50 rotates downward.

[0087] As shown, Figure 6As shown, when the air guide body 50 is turned downward from the highest position to a preset position, the interval between the first air guide surface 501 and the air guide area is gradually expanded, and the ratio of the linear distance L2 between the first air guide surface 501 and the front end of the air guide area to the linear distance L1 between the first air guide 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 low, and the cold air shower is settled, and when the cold air contacts the human body, the cold air speed is more moderate, and the user feels comfortable.

[0088] In some alternative embodiments of the present application, as shown in Figure 16 、 Figure 17 The air guide body 50 is vertically slidably arranged on the shell 10, and is driven to vertically move by a driving device and a transmission device 110. The driving device is a motor, and the transmission device 110 is a meshed gear and rack.

[0089] In some embodiments of the present application, the wall-mounted air conditioner indoor unit further comprises an air guide plate 60. The air guide plate 60 is rotatably arranged between the second air guide surface 502 and the lower edge of the air outlet 40, and can open the interval between the second air guide surface 502 and the lower edge of the air outlet 40. The air guide plate 60 can also close the interval between the second air guide surface 502 and the lower edge of the air outlet 40 at a certain position. For example, the air guide plate 60 and the second air outlet section 104 can be in the same plane, and at the same time, the interval between the second air guide surface 502 and the lower edge of the air outlet 40 is closed. When the wall-mounted air conditioner indoor unit blows cold air, all the cold air is guided from the interval between the first air guide surface 501 and the air guide area to flow out in front and upward, and the situation of cold air directly blowing to the human body is eliminated. The air guide plate 60 can also be used to separate the air flow, and guide the air flow from the air outlet into the interval between the first air guide surface 501 and the air guide area and the interval between the second air guide surface 502 and the lower edge of the air outlet. The air guide plate 60 is rotatably arranged around the front end thereof, and when the hot air is blown, the air guide plate 60 can be rotated to a vertical position, so that all the hot air is blown downward.

[0090] 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 arranged in an inclined manner with the front low and the back high. Of course, the air guide plate 60 can also be arranged in an inclined manner.

[0091] In some embodiments of the present application, the baffle 80 is fixedly arranged between the lower edge of the air outlet 40 and the second air guide surface 502. For example, in the initial position of the air guide body, the baffle 80 is fixedly arranged between the lower edge of the air outlet 40 and the lower edge of the second air guide 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 fixedly arranged at the lower edge of the air outlet 40 and the second air guide surface 502 is provided with micro-holes, which are vertically arranged so that the air passing through the micro-holes is blown vertically downward. Of course, in some alternative embodiments, the micro-holes can also be arranged towards the direction perpendicular to the surface of the baffle 80. In this embodiment, the air guide plate 60 can not be provided, and if the air guide plate 60 is provided, the air guide plate 60 can be arranged above the baffle 80.

[0092] In some embodiments of the present application, the baffle 80 can be a flat plate arranged horizontally; or the baffle 80 is a flat plate arranged obliquely and in the same plane as the second air outlet section. Of course, the baffle 80 can also have other shapes, for example, the cross-sectional profile of the baffle 80 is triangular, the upper surface of the baffle 80 is in the same plane as the second air outlet section 104, and the lower surface of the baffle 80 is arranged horizontally. The triangular profile can guide the air flow out of the lower edge of the air outlet 40 to flow forward and downward, so that the baffle 80 has the function of guiding the air flow.

[0093] In some embodiments of the present application, the lower edge of the air outlet 40 extends downward to form an air guide wall, the included angle C between the second air guide surface 502 and the horizontal plane is between 70° and 110°, and the air guide wall is arranged in a spaced manner with the second air guide surface 502. The air guide wall and the second air guide surface 502 form a lower air duct for downward air flow, and the air flow passing through the lower air duct is blown downward. The lower edge of the air outlet is arranged in a rounded manner.

[0094] In some embodiments of the present application, the air guide plate 60 is rotatably arranged in the space between the second air guide surface 502 and the lower edge of the air guide wall. The air guide plate 60 has the function of guiding and dividing the air flow in addition to the function of opening or closing the space between the second air guide surface 502 and the air guide wall. When the side edge of the air guide plate 60 away from the rotation axis 108 points to the air outlet 40, the side edge enters the air outlet 40, thereby dividing the air flow from the air outlet 40 into two parts, one part flowing out from one side surface of the air guide plate 60 and the other part flowing out from the other side surface of the air guide plate 60. The two parts of air flow enter the space between the first air guide surface 501 and the air guide area and the space between the second air guide surface 502 and the air guide wall, respectively, and are blown out. In the initial position of the air guide body and the air guide plate, the air guide plate is arranged between the lower edge of the second air guide surface and the lower edge of the air guide wall, and the air guide plate is arranged horizontally.

[0095] In some embodiments of the present application, the wall-mounted air conditioner indoor unit further comprises a baffle 80, which is arranged between the lower edge of the air guide wall and the second air guide surface 502. For example, in the initial position of the air guide body, the baffle 80 is fixedly arranged between the lower edge of the air guide wall and the lower edge of the second air guide 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 airflow is scattered by the micro-holes and then blown out, so that the air outlet is softer. The baffle 80 has lower cost, is not prone to failure, and has an attractive appearance while achieving downward air outlet. In this embodiment, the air guide panel 60 can not be provided. If the air guide panel 60 is provided, the air guide panel 60 can be arranged above the baffle 80.

[0096] Further, the baffle 80 can be a horizontally arranged flat plate. Of course, the baffle 80 can also have other shapes. For example, the cross-sectional profile of the baffle 80 is triangular, the upper surface of the baffle 80 is in the same plane as the second air outlet section 104, and the lower surface of the baffle 80 is horizontally arranged. The triangular profile can guide the airflow flowing out of the lower edge of the air outlet 40 to flow forward and downward, so that the baffle 80 has the function of guiding the airflow direction. The rear end of the lower surface of the baffle 80 is the lower edge of the air guide wall.

[0097] At this point, those skilled in the art should recognize that although the present application has been fully illustrated and described herein with reference to a plurality of exemplary embodiments, many other variants or modifications in accordance with the principles of the present application can be directly determined or deduced from the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
