As shown in FIGS. 1 to 7 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 and a plurality of guides arranged along the length direction of the casing 10 (ie, the X direction marked in FIG. 1 ). The wind board 50, as shown in FIG. 1, is provided with two wind guide boards. The airflow blown out from the inside of the casing 10 is a blower airflow. When the air conditioner is cooling, the supply air flow is cold air; when the air conditioner is heating, the supply air flow is hot air. The plurality of air guide plates 50 are used to guide the air flow output from the casing 10 . Each air deflector 50 corresponds to an indoor area, and each air deflector 50 is matched with a driving device 70 to be independently controlled. The air guide angles of each air guide plate 50 are adjusted individually, which realizes the divisional adjustment of the air supply airflow, meets the different needs of users in different indoor areas, and makes the air supply control of the air conditioner more refined. For example, as shown in Figure 1, the left air deflector can be used to supply air upward to the area covered by it, and the right air deflector can be made to supply air relatively sinking to the area covered by it, so that the air outlet can blow out multiple strands of different heights at the same time. air flow. The wind deflecting angle of each wind deflector 50 can be operated by a user, for example, by a remote control. A human body detection device can also be set up to detect information such as the area where the human body is located, the surface temperature, etc., so that the controller can obtain the detection information, and control the air deflector corresponding to the area according to the preset program, so as to realize the direct blowing of the air flow to the human body and avoidance. Human body and other air supply effects.

The number of the wind deflectors 50 can be two, as shown in FIG. 1 to FIG. 3 . The number of the wind deflectors 50 may also be three, four or more.

As shown in FIG. 1 and FIG. 2 , an air outlet 12 is opened on the housing 10 for outputting the air supply air. A plurality of air guide plates 50 are arranged at one air outlet 12 . That is, one air outlet 12 corresponds to a plurality of air guide plates 50 . In some alternative solutions, multiple air outlets may also be provided, so that each air outlet corresponds to one air deflector, or each air deflector may correspond to multiple air outlets.

As shown in FIG. 2 , the wall-mounted air conditioner indoor unit may include an evaporator 20 , a fan 30 , an air duct 40 , and a swing blade 60 . The evaporator 20 is used for heat exchange with the air entering the housing 10 from the air inlet 11 to form a supply air flow. The inlet of the air duct 40 faces the evaporator 20 , and the outlet communicates with the air outlet 12 . The blower 30 may be a cross-flow blower, which is disposed at the inlet of the air duct 40 to promote the flow of air from the evaporator 20 to the air outlet 12 . The swing blades 60 are used to swing the wind left and right.

The structure of the air guide plate 50 in the wall-mounted air conditioner indoor unit will be described below.

FIG. 3 is a schematic structural diagram of two air guide plates in the wall-mounted air conditioner indoor unit shown in FIG. 1; FIG. 4 is an enlarged view of the M position of the air guide plate shown in FIG. 3; Schematic diagram from another perspective; FIG. 6 is an N-N cross-sectional view of the wind deflector shown in FIG. 5 ; FIG. 7 is a partial structural schematic diagram of the wind deflector shown in FIG. 1 from another perspective.

As shown in FIGS. 3 to 7 , the wind deflector 50 according to the embodiment of the present invention may generally include a wind deflector body 51 and a plurality of wind raising parts 52 . The air deflector body 51 is used to be installed at the air outlet 12 of the casing 10 of the wall-mounted air conditioner indoor unit. As shown in FIGS. 1 to 6 , the air deflector body 51 can be rotatably mounted on the housing 10 (rotate around the x-axis, and the x-axis is marked in the drawings).

The function of the air deflector 50 is to open and close the air outlet 12 , and can also be used to adjust the air outlet angle of the air outlet 12 . The airflow blown out from the inside of the housing 10 through the air outlet 12 is the air supply airflow. When the air conditioner is cooling, the supply air flow is cold air; when the air conditioner is heating, the supply air flow is hot air. The air deflector body 51 is in the shape of a long plate, and has two side surfaces (two surfaces with larger areas), a first side surface 511 and a second side surface 512 . The wind deflector body 51 is attached to the air outlet 12 so as to extend horizontally in the longitudinal direction (parallel to the x-axis direction in FIG. 3 ). Both ends of the wind deflector body 51 in the width direction (parallel to the y-axis direction of FIG. 3 ) are a first end (A end) and a second end (B end), respectively.

Each blowing portion 52 is protruded from the first side surface 511 of the air deflector body 51 , and a drainage channel 516 is defined by the first side surface 511 of the air deflector body 51 . In addition, an outlet 5161 of the aforesaid drainage channel 516 is formed on the side of the blowing portion 52 toward the first end (end A) of the air deflector body 51 , see FIG. 6 . Correspondingly, the air deflector body 51 is formed with a plurality of drainage openings 515 penetrating both sides thereof, and each drainage opening 515 is communicated with a drainage channel 516 . The outlet of 516 flows out.

Each blowing part 52 is configured such that when the air deflector 50 is in the position with the first side 511 facing upward and the first end (end A) facing forward (when the indoor unit of the wall-mounted air conditioner is normally installed, the side against the wall is the rear side, the side away from the wall is the front side, which defines the front-rear direction, the direction of the front side is marked in FIG. When the air flow direction is changed, a negative pressure is formed at the first side 511 to drive the ambient air on the other side of the air deflector body 51 (that is, the side facing the second side 512) through the drainage port 515 and the drainage channel 516, After flowing out from the outlet of the drainage channel 516 , the supply air flow is merged, referring to FIG. 1 .

Specifically, under the guidance of the blowing part 52, the air supply air is gradually moved away from the first side surface 511, which reduces the airflow density at the first side surface 511 of the air deflector body 51, forming a negative pressure area (S in FIG. 2 ). area roughly represents the negative pressure area range). Under the suction of the negative pressure area, the ambient air on the second side of the air deflector body 51 enters the negative pressure area through the drainage port 515 opened on the air deflector body 51, and then merges into the air supply airflow to form a mixed air effect . When the air conditioner is cooling, the mixing of ambient air into the air supply airflow can properly increase the temperature of the air supply airflow; when the air conditioner is heating, the mixing of ambient air can appropriately reduce the temperature of the air supply airflow, which makes the air supply airflow more comfortable and achieves Air-conditioned comfort.

The utility model realizes the air mixing function by improving the air guide plate without changing other structures of the wall-mounted air conditioner indoor unit.

The wall-mounted air conditioner indoor unit of the utility model can take into account both the air outlet angle and the air volume. For example, in order to improve the air supply comfort, when the wall-mounted air conditioner indoor unit is refrigerating, it is usually desirable that the air deflector guides the cold air to blow out vertically upward as much as possible. However, when the air deflector of the traditional wall-mounted air conditioner indoor unit is rotated to the upper blowing angle close to the limit, the angle between the air deflector and the plane where the air outlet is located is too small, that is, the opening degree is very small (the opening degree of the air deflector refers to When the air deflector completely closes the air outlet, the opening degree is zero. When the air deflector fully opens the air outlet (refer to Figure 2), the opening degree is 100%, and the air outlet is the smoothest). The air plate will seriously block the air outlet, and the air volume will become very small. This limits the wind guide angle range of the wind deflector. Especially in the vertical wind guide, it is difficult to take into account the wind guide angle and air volume.

In the embodiment of the present invention, the wind raising part 52 can guide the wind upward. Therefore, during the cooling operation of the indoor unit of the wall-mounted air conditioner, it is not necessary to rotate the air deflector body 51 to a state that is too close to vertical (that is, close to the state of closing the air outlet), so as to ensure that the air deflector 50 has a large enough opening. Avoid air volume being affected. In this way, the wall-mounted air conditioner indoor unit takes into account both the air supply angle and the air volume.

In some embodiments, all the blowing parts 52 can be arranged on the wind deflector body 51 in multiple rows spaced along the width direction of the wind deflector body 51 , and each blowing part 52 in each row is arranged along the guide plate body 51 . The wind panel bodies 51 are arranged at intervals in the longitudinal direction. For example, as shown in FIG. 3 , all the blowing parts 52 are arranged in two rows. By arranging the wind blowing parts 52 in multiple rows, wind blowing and air mixing can be performed at different positions in the width direction of the wind deflector body 51 , and the wind blowing and wind mixing effect is ensured. Further, the wind-raising parts 52 of any two adjacent rows can be dislocated in the longitudinal direction of the wind deflector body 51 , for example, as shown in FIG. 3 . That is, the coordinates in the longitudinal direction of the wind deflector body 51 of the wind raising parts 52 in two adjacent rows are different from each other. In this way, the plurality of wind blowing parts 52 can cover each position in the longitudinal direction of the wind deflector body 51 as much as possible, and the air mixing and the wind blowing process of the two adjacent rows of wind blowing parts 52 can be reduced.

In addition, in some alternative embodiments, all the wind raising parts 52 can also be arranged in a row at intervals along the length direction of the wind deflector body 51 .

In some embodiments, as shown in FIGS. 3 to 6 , the wind raising part 52 includes a wind raising plate 522 and two side plates 523 . The wind lifter 52 and the wind deflector body 51 can be integral parts made by an integral molding process. The wind blowing plate 522 starts from the first side surface 511 and extends toward the first end (end A) of the wind deflector body 51 and gradually away from the first side surface 511 . The two side plates 523 respectively extend from the two sides of the wind-raising plate 522 toward the first side surface 511 , and are sealedly connected with the first side surface 511 . This structure can make the wind-raising plate 522 better perform the wind-raising function.

Further, as shown in FIG. 7 , the distance between the two side plates 523 is gradually increased in the direction from the two side edges of the wind blowing plate 522 to the first side surface 511 . In other words, the two side plates 523 are made to extend away from each other from the two side edges of the wind blowing plate 522 to the first side surface 511 . The two side panels 523 are so inclined and arranged to perform the functions of raising wind and accelerating. Specifically, since the two side plates 523 are not perpendicular to the first side surface 511 , their surfaces also have an upward component, so that their surfaces have a certain wind-raising function. In addition, a channel that is tapered along the airflow direction is formed between two adjacent air blowing parts 52 . After passing through this channel, the speed of the supply air increases, and passes through the side of the outlet 5161 of the drainage channel 516 at a faster flow rate, so as to form a negative pressure area on the side of the outlet 5161, attracting the ambient air flowing out of the drainage channel 516 and this part. Air flow mix. At the same time, the airflow guided by the air blowing plate 522 forms a negative pressure on the upper edge of the outlet 5161 of the drainage channel 516 to attract ambient air. Therefore, a negative pressure area is formed on the upper side and both sides of the drainage channel 516, and the negative pressure area surrounds the outlet 5161 of the drainage channel 516, which makes the air mixing range larger and the mixing intensity stronger.

Since the distance between the two side plates 523 gradually increases in the direction from the two side edges of the air blowing plate 522 to the first side surface 511 , the outlet of the drainage channel 516 forms a trapezoidal structure, as shown in FIG. 7 . The lengths of the top and bottom sides of the trapezoidal outlet are respectively a and b, preferably 0.5≤a/b≤0.9, preferably a/b=0.7, so that the wind and acceleration effects of the side plate 523 are the best.

As shown in FIG. 7 , in the embodiment in which two rows of air blowing parts are provided, the first row of air raising parts 52 (the row close to the first end (the A end) of the air deflector body 51 ) can have a The length b of the bottom edge of the trapezoidal outlet is greater than the length e of the bottom edge of the trapezoidal outlet of the drainage channel of the second row of air lifts 52 (a row close to the second end (end B) of the air deflector body 51 ), so that the supply air flow Get more lift and mix near the outflow deflector. Further, set the shortest distance between the trapezoidal bases of the drainage channels of the first row of adjacent air lifts as c, preferably 1.5≤b/c≤5.5, more preferably b/c=4. Similarly, the closest distance between the trapezoidal bases of the drainage channels of the second row of adjacent air lifts is f, preferably 0.5≤e/f≤4, more preferably e/f=1.

In some embodiments, as shown in FIG. 6 , the projection of the air raising plate 522 on the first side surface 511 can completely cover the air drainage opening 515 and be located within the range of the air deflector body 51 . Specifically, making the projection of the air raising plate 522 on the first side surface 511 completely cover the drainage opening 515 means making the end (E end) of the raising air plate 522 extend beyond the first end of the air guiding plate body 51 near the air guiding plate 515 . the D terminal. The projection of the wind deflector 522 on the first side 511 is located within the range of the wind deflector body 51 , which means that the end (E end) of the wind deflector 522 is compared with the first end (A end) of the wind deflector body 51 . end) is retracted a certain distance in the direction of the second end (end B) of the air deflector body 51 . It can also be understood in this way that a vertical line is drawn at the end (E end) of the wind panel 522 to the first side surface 511 of the wind panel body 51, and the vertical foot will fall on the first side surface 511 itself rather than the extension surface of the first side surface 511. . In this way, the section of the air deflector body 51 protruding from the air raising plate 522 can guide and block the ambient air flowing out of the drainage channel 516 to a certain extent, so that it can be better mixed with the supply air flow. In addition, when the air deflector body 51 closes the air outlet 12 , the air blowing plate 522 can be prevented from contacting the upper edge of the air outlet 12 .

In some embodiments, as shown in FIG. 6 , at the junction of the air raising plate 522 and the air guiding plate body 51 (ie, the starting end of the extension of the air raising plate 522 ), the tangent of the air raising plate 522 and the air guiding plate body The included angle of the tangent to 51 is θ. The inventor has found through research that if the angle is too small, the wind effect angle will be insufficient, and if the angle is too large, the wind direction turning angle will be too large and the wind resistance will be too large when the air supply air flows from the surface of the first side 511 to the surface of the wind plate 522 . The most preferred range of this angle is between 10° and 60°. θ is preferably 25°. In addition, this angle range can also reach the maximum drainage volume, while minimizing the loss of air-conditioning air volume.

As shown in FIG. 3 to FIG. 6 , the wind blowing plate 522 can be a flat plate, and the tangential direction thereof is parallel to the plate surface. The air deflector body 51 can be an arc-shaped plate in which the first side surface 511 is concave and the central axis is parallel to the length direction of the air deflector body 51 .

In some embodiments, as shown in FIGS. 2 and 3 , each wind deflector 50 further includes at least one rotating arm 53 , one end of which is connected to the driving device 70 inside the housing 10 and the other end is connected to the wind deflector body 51 . Driven by the driving device 70 , the rotating arm 53 drives the air deflector body 51 to rotate upwardly around the first end of the rotating arm 53 to close the air outlet 12 , or rotate downward to open the air outlet 12 . A plurality of rotating arms 53 can be provided, so that the plurality of rotating arms 53 are arranged at intervals along the length direction of the air deflector body 51 . The driving device 70 includes a stepping motor for directly or indirectly driving the rotating arm 53 to rotate.

FIG. 8 is a schematic view of the state of the wall-mounted air conditioner indoor unit shown in FIG. 2 after the air deflector is further opened. As shown in FIG. 2 and FIG. 8 , the air outlet 12 may be located at the lower part of the front side of the casing 10 and opened forward and downward. The entire turning arm 53 is a bent arm with one bending and the bending opening is downward. The driving device 70 is installed at the bottom wall of the air duct 40 . The purpose of setting the curved arm is to make the first side 511 face the air outlet 12 at every angle of the air deflector 50 when the air outlet 12 is opened, so that the supply air flow is guided by the first side 511, and the second side 512 faces away from the air outlet 12. The air outlet 12 is in contact with the ambient air, which is beneficial to realize the air mixing function of the air deflector 50 . Moreover, the setting of the curved arm also facilitates the rotation of the air deflector body 51 to the lower side of the housing 10 so as to completely avoid the supply air flow from the air outlet 12, that is, to completely open the air outlet 12, so that the air deflector 50 does not block the airflow at all .

On this basis, one or more inner guide plates 80 can be additionally arranged at the air outlet 12 , and the inner guide plates 80 can be rotatably installed at the air outlet 12 and located inside the air guide plate 50 for adjusting the size of the air outlet 12 . Wind direction up and down. That is, the air guide plate 50 is made to play more functions of opening and closing the air outlet and air mixing, and the inner guide plate 80 is made to play the role of wind guide and up-down wind.

By now, those skilled in the art will recognize that although various exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, Numerous other variations or modifications consistent with the principles of the present invention are directly identified or derived from the disclosure of the present invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
