Schematic diagram of the state when it is opened; FIG. 5 is a schematic diagram of the state of the wall-mounted air conditioner indoor unit shown in FIG. 3 when the second air outlet 12 is opened.

As shown in FIGS. 1 to 5 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 , an air duct member 40 , at least one first air guide plate 51 and at least one second air guide plate 52. The housing 10 is provided with a first air outlet 11 facing forward and a second air outlet 12 facing downward. The first air outlet 11 may be disposed at the bottom of the front of the casing 10 , and the second air outlet 12 may be disposed at the front of the bottom of the casing 10 . The air duct member 40 is arranged in the casing 10, and is used to send the air supply air flow in the housing 10 (when the air conditioner is in the cooling mode, the air supply air flow is cold air; in the heating mode, the air supply air flow is hot air) to the first outlet. The air opening 11 and/or the second air outlet 12 are guided. The number of the first air guide plates 51 is one or more, such as one shown in FIG. 1 , which is arranged at the first air outlet 11 for opening and closing the first air outlet 11 and guiding the outlet of the first air outlet 11 . wind direction. The number of the second air deflectors 52 is one or more, such as one shown in FIG. 1 , which is disposed at the second air outlet 12 for opening and closing the second air outlet 12 and guiding the outlet of the second air outlet 12 wind direction. At least one side surface of the first wind deflector 51 is a wave surface. At least one side surface of the second wind deflector 52 is a wave surface. The first air guide plate 51 and the second air guide plate 52 are both plate-shaped, and the two large-area surfaces of the plates are side surfaces. The wavy surface means that the side surface has multiple convex areas and concave areas, and the convex area and the concave area transition smoothly to form a wave-like shape.

The indoor unit of the wall-mounted air conditioner may be an indoor unit of an air conditioning system that performs cooling/heating by a vapor compression refrigeration cycle system. An air inlet 13 may be opened on the casing 10 , and a heat exchanger 20 and a cross-flow fan 30 are arranged in the casing 10 . Under the action of the cross-flow fan 30, the indoor air enters the housing 10 from the air inlet 13, exchanges heat with the heat exchanger 20 to form a supply air flow, and then flows to the first air outlet 11 and/or the first air outlet 11 through the guidance of the air duct member 40. or the second air outlet 12 .

In the embodiment of the present invention, the housing 10 of the wall-mounted air conditioner indoor unit has the first air outlet 11 facing forward, which is specially used for supplying air to the front, the upper front or the lower front. Compared with the one with only one air outlet, In the solution, the angle of the first air outlet 11 for upward air supply can obviously be designed to be larger. In addition, a downward second air outlet 12 is provided, which can be specially used for downward air supply. Compared with the solution with only one air outlet, the angle of the second air outlet 12 for downward air supply can obviously be designed to be larger. . For example, as shown in FIG. 5 , the second air outlet 12 is made to blow air downward completely vertically. Therefore, in general, compared with the solution of designing one air outlet, the air supply angle range of the wall-mounted air conditioner indoor unit of the embodiment of the present invention is larger. In addition, by switching the flow path of the air duct member 40 , the wall-mounted air conditioner indoor unit can selectively discharge air from the first air outlet 11 and/or the second air outlet 12 . For example, in the cooling mode, only the first air outlet 11 can be ventilated, and the air can be sent forward or upward, so that the cold air avoids the human body, and the cold air reaches the highest point and then scatters downward to realize a kind of "shower" type" cooling experience, as shown in Figure 4. In the heating mode, only the second air outlet 12 can be used to discharge air, so that the hot air blows directly down the bottom surface in a near vertical downward direction, and then rolled up in a carpet style to achieve a warm foot experience, as shown in Figure 5. In addition, the air duct member 40 can also be adjusted to a position where the guide air flow is directed to the first air outlet 11 and the second air outlet 12 at the same time, so that the first air outlet 11 and the second air outlet 12 can supply air at the same time, so as to achieve a large air volume air supply.

In addition, in the embodiment of the present invention, since at least one side surface of the first wind deflector 51 and at least one side surface of the second wind deflector 52 are wavy surfaces, after the air flow passes through the wavy surfaces, the length direction of the wind deflector (Fig. 1 x direction) The air outlet angles of different positions are different, forming a multi-dimensional air supply effect, making the air supply air more soft and dispersed, very close to the natural wind, making people feel comfortable.

In some embodiments, as shown in FIGS. 1 to 5 , one end of the first air deflector 51 (when the first air deflector 51 is in the state of closing the first air outlet 11 , the end is the upper end) can be rotated It is mounted on the casing 10 , and its rotation axis is located at the upper edge of the first air outlet 11 and is parallel to the length direction of the casing 10 . One end of the second air deflector 52 (when the second air deflector 52 is in the state of closing the second air outlet 12, this end is the front end) is rotatably mounted on the housing 10, and its rotation axis is located at the second air outlet. 12 at the front edge and parallel to the length of the housing 10 . In this way, when the first air outlet 11 is opened, the first air deflector 51 guides the air flow at the top of the air supply airflow, and blocks the air supply air (especially the cold air during cooling) from the upper edge of the first air outlet 11 downward. backflow. In addition, when the second air outlet 12 blows out, the second air deflector 52 can be rotated to a vertical position in front of the second air outlet 12 , so that the air flow is basically directed from the rear side of the second air deflector 52 . The downward flow (except for a small part passing through the air diffuser micro-holes) is guided by the second air deflector 52 to enhance the effect of downward blowing, as shown in FIG. 5 . In addition, when the first air outlet 11 blows out, the first air guide plate 51 and the second air guide plate 52 can be rotated to be parallel to each other to form an air guide channel (equivalent to extending the air channel 401), Strengthen the wind guide effect. For example, both the first air deflector 51 and the second air deflector 52 are gradually extended forward from the rear to the front, so that the first air deflector 51 and the second air deflector 52 cooperate to direct the air flow downward and upward. Guide, strengthen the upward wind effect. The casing 10 may be provided with motors for respectively driving the first wind deflector 51 and the second wind deflector 52 to rotate.

In addition, as shown in FIG. 1 , the rearward side 513 of the first air deflector 51 can be a corrugated surface when the first air outlet 11 is closed; the forward side 515 is a non-corrugated surface, such as a flat surface or curved surfaces with little curvature. When the second air deflector 52 is in the state of closing the second air outlet 12, the upward facing side 523 can be a corrugated surface; the downward facing side 525 can be a non-corrugated surface, such as a flat surface or a curved surface with little curvature. Since the side surface 513 of the first wind deflector 51 and the side surface 523 of the second wind deflector 52 play the role of soft air flow during the wind guiding process, they are wavy surfaces for soft air flow. The side 515 of the first air guide plate 51 and the side surface 525 of the second air guide plate 52 face outward when the corresponding air outlets are closed, making them non-wavy surfaces, so that the The look remains beautiful.

In some embodiments, as shown in FIG. 1 , the first air deflector 51 may be provided with a plurality of air diffusing micro-holes 511 . In this way, when the first air outlet 11 is ventilated, the first air deflector 51 can be opened at a smaller opening angle or the first air outlet 11 can be closed, so that part or All of them are blown out through the air-scattering micro-holes 511, so that the air supply air flow is softer and more comfortable. In addition, in the state where the first air guide plate 51 opens the first air outlet 11, the supply air flows from one side of the first air guide plate 51 at a high speed to form a negative pressure, which can also attract the other side of the first air guide plate 51. The indoor air on the side is merged into the air supply airflow through the air diffusing micro-holes 511 to form a mixed air effect. During cooling, the temperature of the cold air is increased to a certain extent by mixing indoor room temperature air; during heating, the temperature of the hot air is decreased by mixing indoor air. In short, the mixing process makes the temperature difference between the air supply air flow and the room temperature air smaller, and the human body feels more comfortable. In addition, since the side surface 513 of the first air deflector 51 is a wavy surface, when the supply air flow passes through the wavy surface, the inside of the concave area of the wavy surface is not easy to penetrate due to the high-speed airflow, which will generate a greater negative pressure, causing the concave area to be lowered. The wind mixing process of the scattered wind micro-holes at the area is more intense. The ratio of the diameter of the air diffusing holes 511 to the width of the first air deflector 51 can be between 1/8 and 1/5, so that the wind loss can be reduced. Similar to the first air deflector 51 , the second air deflector 52 may be provided with a plurality of air diffusing micro-holes 522 . In addition, the ratio of the diameter of the air diffusing micro-holes 522 to the width of the second air deflector 52 can also be set between 1/8 and 1/5.

In some embodiments, the air duct member 40 may guide the supply air flow in the housing 10 to the first air outlet 11 or the second air outlet 12 . For example, as shown in FIGS. 3 to 5 , the air duct member 40 may include an upper volute 41 , a lower volute 42 and an air duct switching plate 43 . The upper volute 41 and the lower volute 42 together define an air duct 401 , and the air duct 401 communicates with the first air outlet 11 and the second air outlet 12 . The front end of the air passage switching plate 43 is rotatably installed between the first air outlet 11 and the second air outlet 12 , and has its rear end abutting against the lower volute 42 to close the air passage 401 to the second air outlet 12 , and the upward blowing position of the passage from the air duct 401 to the first air outlet 11, as shown in FIG. 4; The passage, the downward blowing position of the passage from the air passage 401 to the second air outlet 12 , as shown in FIG. 5 . Further, the air path switching plate 43 can be configured to be gradually inclined upward from the back to the front when it is in the upward blowing position, so as to be able to upwardly guide the supply air flow, as shown in FIG. 4 ; when it is in the downward blowing position, from It is set to be inclined forward and downward gradually, which is conducive to sinking and guiding the airflow, as shown in Figure 5.

As shown in FIG. 3 , the upper volute 41 may be provided with a stepped portion 411 , and the lower volute 42 may be provided with a stepped portion 422 to accommodate the rear end of the air passage switching plate 43 so that the rear end of the air passage switching plate 43 The connection with the surfaces of the upper volute 41 and the lower volute 42 has a smoother transition to avoid excessive wind resistance caused by the rear end of the air path switching plate 43 suddenly protruding from the surfaces of the upper volute 41 and the lower volute 42 .

In some embodiments, the number of the first air guide plates 51 can be multiple, and the number of the second air guide plates 52 can be multiple. A plurality of first air guide plates 51 are arranged at the first air outlet 11 along the length direction of the housing 10 . When the air guide plates 51 are all in the closed state, the entire first air outlet 11 can be closed. A plurality of second air guide plates 52 are arranged at the second air outlet 12 along the length direction of the casing 10 , each second air guide plate 52 is used to open and close a part of the second air outlet 12 When the air guide plates 52 are all in the closed state, the second air outlet 12 can be closed as a whole. Since each air outlet is provided with multiple air deflectors, zoned air guiding and on-demand air guiding are realized. In addition, different air guide plates are located at different air guide angles, which can realize a multi-dimensional air supply effect in the upper and lower directions, and improve the cooling/heating speed. Specifically, taking the first air outlet 11 as an example, different first air guide plates 51 face different areas in the room, and the corresponding first air guide plates 51 can be independently controlled according to the air supply requirements of users in each area. Wind angle, to meet the needs of personalized air supply. Similarly, the second air outlet 12 can have the same air supply effect, which is not repeated here.
