Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a wall-mounted air-conditioning indoor unit. Background Art

[0002] With the development of the times and the advancement of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners.

[0003] However, in order to achieve faster cooling and heating, it is inevitable to supply air with a large air volume. However, when the cold or hot air with too high wind speed blows directly on the human body, it will inevitably cause discomfort to the human body. If the human body is directly blown by cold air for a long time, it will also cause air conditioning disease.

[0004] Therefore, how to achieve comfortable air supply of air conditioners has become a technical problem that needs to be solved urgently in the air conditioning industry. Summary of the invention

[0005] An object of the present invention is to provide a wall-mounted air conditioner indoor unit that overcomes the above problems or at least partially solves the above problems.

[0006] The purpose of the present invention is to enable the air guide plate to have the functions of guiding air and mixing air, so as to make the air supply flow more comfortable.

[0007] A further object of the present invention is to enable the wind guide plate to have a better wind-raising function so as to achieve the upward blowing of cold wind.

[0008] In particular, the present invention provides a wall-mounted air conditioner indoor unit, comprising a plurality of air guide plates arranged along the length direction of its housing, for guiding the air supply airflow output from the housing, each air guide plate comprising:

[0009] An air deflector body, used for being mounted on the housing; and

[0010] A plurality of wind-raising portions, each wind-raising portion is protrudingly arranged on the first side surface of the wind deflector body to define a drainage channel with the first side surface of the wind deflector body, and an outlet of the drainage channel is formed on a side of the wind deflector body facing the first end of the wind deflector body, and a plurality of drainage ports penetrating two sides of the wind deflector body are formed on the wind deflector body, each drainage port is connected to a drainage channel, and each wind-raising portion is configured as follows:

[0011] When the air guide plate is in a position with the first side facing upward and the first end facing forward, the supply air flow changes its direction when flowing through the wind-raising portion, forming a negative pressure at the first side to drive the ambient air on the other side of the air guide plate body to merge into the supply air flow through the drainage port and the drainage channel in sequence.

[0012] Optionally, each wind-raising portion includes: a wind-raising plate, extending from the first side toward the first end of the wind guide plate body and gradually away from the first side; and two side plates, extending from two side edges of the wind-raising plate toward the first side and connected to the first side.

[0013] Optionally, in the direction from the two side edges of the wind-raising plate to the first side surface, the distance between the two side plates gradually increases.

[0014] Optionally, at the junction of the wind raising plate and the wind guide plate body, an angle between a tangent line of the wind raising plate and a tangent line of the wind guide plate body is between 10° and 60°.

[0015] Optionally, the projection of the wind-raising portion on the first side surface completely covers the air outlet and is located within the range of the air guide plate body.

[0016] Optionally, all the wind-raising portions are arranged in a row at intervals along the length direction of the wind guide plate body.

[0017] Optionally, all the wind-raising portions are arranged on the wind guide plate body in a plurality of rows spaced apart along the width direction of the wind guide plate body; and the wind-raising portions in each row are spaced apart along the length direction of the wind guide plate body.

[0018] Optionally, the wind raising portions of any two adjacent rows are staggered in the length direction of the wind guide plate body.

[0019] Optionally, an air outlet is provided on the shell for outputting the air supply airflow; and a plurality of air guide plates are arranged at one air outlet.

[0020] Optionally, each air guide plate also includes at least one rotating arm, one end of the rotating arm is connected to a driving device located inside the shell, and the other end is connected to the air guide plate body, so that under the drive of the driving device, the air guide plate body is driven to rotate upward around the first end of the rotating arm to close the air outlet, or rotate downward to open the air outlet; and an inner guide plate is also installed at the air outlet, which is located on the inner side of the air guide plate.

[0021] The wall-mounted air conditioner indoor unit of the present invention is provided with a plurality of air guide plates arranged along the length direction of the shell, each air guide plate is independently controlled, and the air guide angles do not affect each other, so that the air supply airflow is adjusted in different zones, meeting the different needs of users in different indoor areas, and making the air supply control of the air conditioner more refined. For example, the air guide plate on the left side can be made to supply air upward to the area it covers, and the air guide plate on the right side can be made to supply air downward to the area it covers, etc.

[0022] In the wall-mounted air-conditioning indoor unit of the present invention, a plurality of wind-raising parts and drainage holes are provided on the air guide plate body to have an air mixing function. Specifically, when the supply air flow passes through the first side surface of the air guide plate body, the wind-raising part changes the flow direction of the supply air flow, making it away from the first side surface of the air guide plate body, thereby reducing the air flow density at the first side surface and forming a negative pressure. Under the attraction of the negative pressure area, the ambient air on the other side of the air guide plate body (the side facing the second side surface of the air guide plate body) enters the negative pressure area through the drainage port provided on the air guide plate body, and then merges into the supply air flow, forming a mixed air effect. When the air conditioner is cooling, the mixing of ambient air can appropriately increase the temperature of the supply air flow; when the air conditioner is heating, the mixing of ambient air can appropriately reduce the temperature of the supply air flow, both of which make the supply air flow more comfortable.

[0023] The present invention realizes the air mixing function by improving the air guide plate without changing other structures of the wall-mounted air conditioner indoor unit. This design is very clever, the structure is very simple, the cost is low, and it is very conducive to mass production and promotion.

[0024] Furthermore, in the wall-mounted air conditioner indoor unit of the present invention, the wind-raising portion of the wind guide plate includes a wind-raising plate and two side plates, and the wind-raising plate extends from the first side surface of the wind guide plate body toward the first end of the wind guide plate body and gradually away from the first side surface. The air supply airflow is blown upward under the action of the wind-raising plate, which not only generates a negative pressure area, but also makes the upward blowing angle of the air supply airflow (the angle between the upward air outlet direction and the vertical direction) smaller, so as to better avoid the human body.

[0025] Furthermore, in the wall-mounted air-conditioning indoor unit of the present invention, the distance between the two side plates is gradually increased in the direction from the two side edges of the wind-raising plate to the first side surface, so that a channel that gradually shrinks along the airflow direction is formed between the two adjacent wind-raising portions. The speed of the supply air flow increases after passing through the channel, and it passes through the side of the outlet of the drainage channel at a faster flow rate to form a negative pressure area on the side of the outlet, attracting the ambient air flowing out of the drainage channel to mix with this part of the supply air flow. At the same time, the airflow guided by the wind-raising plate forms a negative pressure at the upper edge of the drainage channel outlet, attracting ambient air. Therefore, negative pressure areas are formed on the upper side and both sides of the drainage channel, and the negative pressure area surrounds the drainage channel outlet, which makes the air mixing force stronger.

[0036] Refer to the following Figures 1 to 8 The wall-mounted air conditioner indoor unit of the embodiment of the present invention is described in detail. In the figure, the wind direction of the air supply airflow is indicated by a solid arrow, and the flow direction of the ambient air is indicated by a hollow arrow.

[0037] Figure 1 is a schematic structural diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; Figure 2 is a schematic cross-sectional view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention.

[0038] like Figures 1 to 7 As shown, the wall-mounted air conditioner indoor unit of the embodiment of the present invention generally includes a housing 10 and a longitudinal direction (i.e., Figure 1 A plurality of air guide plates 50 are arranged in the X direction, for example Figure 1As shown in the figure, two air guide plates are provided. The airflow blown out from the inside of the housing 10 is the supply airflow. When the air conditioner is cooling, the supply airflow is cold air; when the air conditioner is heating, the supply airflow is hot air. Multiple air guide plates 50 are used to guide the supply airflow output by the housing 10. Each air guide plate 50 corresponds to an area in the room, and each air guide plate 50 is matched with a driving device 70 to be independently controlled. The air guide angles of each air guide plate 50 are adjusted separately, so as to realize the zoned adjustment of the supply airflow, meet the different needs of users in different areas of the room, and make the air supply control of the air conditioner more refined. For example Figure 1 As shown, the left wind guide plate can be made to supply air upward to the area it covers, and the right wind guide plate can be made to supply air relatively downward to the area it covers, so that the air outlet can blow out multiple airflows of different heights at the same time. The air guide angle of each wind guide plate 50 can be operated by the user, for example, by a remote control. A human body detection device can also be set to detect information such as the area where the human body is located and the surface temperature, so that the controller obtains the detection information and controls the wind guide plate corresponding to the area according to the preset program, so as to achieve air supply effects such as the air supply airflow blowing directly on the human body or avoiding the human body.

[0039] The number of the air guide plates 50 may be two, such as Figures 1 to 3 The number of the air guide plates 50 may also be three, four or more.

[0040] Can be as Figure 1 and Figure 2 As shown, an air outlet 12 is provided on the housing 10 for outputting the air supply airflow. A plurality of air guide plates 50 are provided at one air outlet 12. That is, one air outlet 12 corresponds to a plurality of air guide plates 50. In some alternative solutions, a plurality of air outlets may be provided, so that each air outlet corresponds to one air guide plate, or each air guide plate corresponds to a plurality of air outlets.

[0041] like Figure 2 As shown, 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 to perform 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 is connected to the air outlet 12. The fan 30 may be a cross-flow fan, which is arranged at the inlet of the air duct 40 to promote air flow from the evaporator 20 to the air outlet 12. The swing blade 60 is used to swing the air left and right.

[0042] The structure of the air guide plate 50 in the wall-mounted air conditioner indoor unit is introduced below.

[0043] Figure 3 yes Figure 1 A schematic diagram of the structure of two air guide plates in a wall-mounted air conditioner indoor unit is shown; Figure 4 yes Figure 3 An enlarged view of the M position of the air guide plate shown; Figure 5yes Figure 3 Another perspective schematic diagram of the air guide plate shown; Figure 6 yes Figure 5 NN sectional view of the wind deflector shown; Figure 7 yes Figure 1 A schematic diagram of the partial structure of the air guide plate from another perspective is shown.

[0044] like Figures 3 to 7 As shown, the air guide plate 50 of the embodiment of the present invention may generally include an air guide plate body 51 and a plurality of wind raising portions 52. The air guide plate body 51 is used to be installed at the air outlet 12 of the housing 10 of the wall-mounted air conditioner indoor unit. Figures 1 to 6 As shown, the air guide plate body 51 is rotatably mounted on the housing 10 (rotatable around the x-axis, which is indicated in the figure).

[0045] The function of the air guide plate 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 shell 10 through the air outlet 12 is the supply airflow. When the air conditioner is cooling, the supply airflow is cold air; when the air conditioner is heating, the supply airflow is hot air. The air guide plate body 51 is in the shape of a long strip, which has two side surfaces (the two sides with larger areas), a first side surface 511 and a second side surface 512. The air guide plate body 51 is in the length direction (parallel to Figure 3 The air guide plate body 51 is installed horizontally at the air outlet 12 in the width direction (parallel to the x-axis direction). Figure 3 The two ends in the y-axis direction) are respectively the first end (end A) and the second end (end B).

[0046] Each wind-raising portion 52 is protrudingly disposed on the first side surface 511 of the wind deflector body 51, and defines a drainage channel 516 with the first side surface 511 of the wind deflector body 51. In addition, the wind-raising portion 52 is formed with an outlet 5161 of the drainage channel 516 on the side facing the first end (end A) of the wind deflector body 51. Figure 6 Correspondingly, the air guide plate body 51 is formed with a plurality of drainage ports 515 penetrating through two sides thereof, each drainage port 515 is connected to a drainage channel 516 , and the airflow enters the drainage channel 516 from the drainage port 515 and then flows out from the outlet of the drainage channel 516 .

[0047] Each wind-raising portion 52 is configured such that: when the wind guide plate 50 is in a position with the first side surface 511 facing upward and the first end (end A) facing forward (when the wall-mounted air conditioner indoor unit is normally installed, the side close to the wall is the rear side, and the side away from the wall is the front side, thereby defining the front-rear direction, Figure 1When the air supply airflow blown out from the air outlet 12 changes its direction when passing through the wind raising portion 52, a negative pressure is formed at the first side surface 511, so as to drive the ambient air on the other side of the air guide plate body 51 (i.e., the side facing the second side surface 512) to flow out from the outlet of the drainage channel 516 through the drainage port 515 and the drainage channel 516, and then merge into the air supply airflow. Figure 1 .

[0048] Specifically, under the guidance of the wind-raising portion 52, the air supply airflow gradually moves away from the first side surface 511, which reduces the airflow density at the first side surface 511 of the air guide body 51, forming a negative pressure area ( Figure 2 The S region in the figure roughly represents the range of the negative pressure region. Under the attraction of the negative pressure region, the ambient air on the second side of the air guide plate body 51 enters the negative pressure region through the air inlet 515 provided on the air guide plate body 51, and then merges into the supply air flow, forming a mixed air effect. When the air conditioner is cooling, the mixing of ambient air into the supply air flow can appropriately increase the temperature of the supply air flow; when the air conditioner is heating, the mixing of ambient air can appropriately reduce the temperature of the supply air flow, which makes the supply air flow more comfortable and realizes comfortable air supply of the air conditioner.

[0049] The present invention realizes the air mixing function by improving the air guide plate without changing other structures of the wall-mounted air conditioner indoor unit. This design is very clever, the structure is very simple, the cost is low, and it is very conducive to mass production and promotion.

[0050] The wall-mounted air conditioner indoor unit of the present invention can take into account both the air outlet angle and the air volume. For example, in order to improve the comfort of air supply, when the wall-mounted air conditioner indoor unit is cooling, it is usually hoped that the air guide plate guides the cold air to blow out as vertically upward as possible. However, when the air guide plate of the conventional wall-mounted air conditioner indoor unit is rotated to an upward blowing angle close to the limit, the angle between the air guide plate and the plane where the air outlet is located is too small, that is, the opening is very small (the opening of the air guide plate refers to the degree to which it opens the air outlet. When the air guide plate completely closes the air outlet, the opening is zero. When the air guide plate fully opens the air outlet (refer to Figure 2 ), the opening is 100%, and the air flow is smoothest), the air guide plate will seriously block the air outlet, and the air volume becomes very small. This limits the air guide angle range of the air guide plate. Especially when the air is guided vertically, it is difficult to take into account both the air guide angle and the air volume.

[0051] In the embodiment of the present invention, the wind lifting part 52 can guide the wind upward. Therefore, when the wall-mounted indoor air conditioner is in cooling operation, it is not necessary to rotate the air guide plate body 51 to a state that is too close to the vertical (i.e., close to the state of closing the air outlet), so as to ensure that the air guide plate 50 has a sufficiently large opening to avoid affecting the air volume. In this way, the wall-mounted indoor air conditioner takes into account both the air supply angle and the air volume.

[0052] In some embodiments, all the wind-raising portions 52 may be arranged on the wind deflector body 51 in multiple rows spaced apart along the width direction of the wind deflector body 51, and the wind-raising portions 52 in each row may be spaced apart along the length direction of the wind deflector body 51. Figure 3 As shown, all the wind-raising parts 52 are arranged in two rows. Arranging the wind-raising parts 52 in multiple rows can raise and mix wind at different positions in the width direction of the wind deflector body 51, thereby ensuring the wind-raising and wind-mixing effects. Furthermore, the wind-raising parts 52 in any two adjacent rows can be staggered in the length direction of the wind deflector body 51, for example Figure 3 That is, the coordinates of the wind-raising parts 52 in two adjacent rows in the length direction of the wind guide body 51 are different. In this way, the plurality of wind-raising parts 52 can cover as many positions in the length direction of the wind guide body 51 as possible, and can reduce the mutual interference of the wind mixing and wind-raising processes of the wind-raising parts 52 in two adjacent rows.

[0053] In addition, in some alternative embodiments, all the wind-raising portions 52 may be arranged in a row at intervals along the length direction of the wind guide plate body 51 .

[0054] In some embodiments, Figures 3 to 6 As shown, the wind-raising portion 52 includes a wind-raising plate 522 and two side plates 523. The wind-raising portion 52 and the wind guide plate body 51 can be an integral part made by an integrated molding process. The wind-raising plate 522 starts from the first side surface 511, extends toward the first end (end A) of the wind guide plate body 51 and gradually away from the first side surface 511. The two side plates 523 extend from the two side edges of the wind-raising plate 522 toward the first side surface 511, and are sealed and connected to the first side surface 511. This structure allows the wind-raising plate 522 to better perform its wind-raising function.

[0055] Furthermore, if Figure 7As shown, in the direction from the two sides of the wind-raising plate 522 to the first side 511, the spacing between the two side plates 523 is gradually increased. In other words, the two side plates 523 are extended away from each other from the two sides of the wind-raising plate 522 to the first side 511. The two side plates 523 are arranged in such an inclined manner to play the wind-raising and acceleration functions. Specifically, since the two side plates 523 are not perpendicular to the first side 511, their surfaces also have an upward component, so that their surfaces have a certain wind-raising function. In addition, a channel that gradually shrinks along the airflow direction is formed between the two adjacent wind-raising parts 52. After the air supply airflow passes through the channel, the speed is increased, and it passes through the side of the outlet 5161 of the drainage channel 516 at a faster flow rate to form a negative pressure area on the side of the outlet 5161, attracting the ambient air flowing out of the drainage channel 516 to mix with the part of the air supply airflow. At the same time, the airflow guided by the wind-raising plate 522 forms a negative pressure at the upper edge of the outlet 5161 of the drainage channel 516, thereby attracting ambient air. Therefore, negative pressure areas are formed on the upper side and both sides of the drainage channel 516, and the negative pressure areas surround the outlet 5161 of the drainage channel 516, which makes the air mixing range larger and the mixing force stronger.

[0056] Since the distance between the two side plates 523 gradually increases in the direction from the two sides of the wind-raising plate 522 to the first side surface 511, the outlet of the drainage channel 516 forms a trapezoidal structure, such as Figure 7 The lengths of the top and bottom sides of the trapezoidal outlet are a and b respectively, preferably 0.5≤a / b≤0.9, preferably a / b=0.7, so that the wind-raising and acceleration effects of the side plate 523 are optimal.

[0057] like Figure 7 As shown, in an embodiment in which two rows of wind-raising parts are provided, the bottom side length b of the trapezoidal outlet of the drainage channel of the first row of wind-raising parts 52 (a row close to the first end (end A) of the wind guide body 51) can be made greater than the bottom side length e of the trapezoidal outlet of the drainage channel of the second row of wind-raising parts 52 (a row close to the second end (end B) of the wind guide body 51), so that the air supply airflow can obtain more wind lifting and mixed air when it is close to flowing out of the wind guide plate. Further, the closest distance between the trapezoidal bottom sides of the drainage channels of adjacent wind-raising parts in the first row is c, preferably 1.5≤b / c≤5.5, and more preferably b / c=4. Similarly, the closest distance between the trapezoidal bottom sides of the drainage channels of adjacent wind-raising parts in the second row is f, preferably 0.5≤e / f≤4, and more preferably e / f=1.

[0058] In some embodiments, Figure 6As shown, the projection of the wind-raising plate 522 on the first side 511 can completely cover the air outlet 515 and be located within the range of the air guide body 51. Specifically, the projection of the wind-raising plate 522 on the first side 511 completely covers the air outlet 515, which means that the end (end E) of the wind-raising plate 522 exceeds the end D of the air outlet 515 close to the first end of the air guide body 51. The projection of the wind-raising plate 522 on the first side 511 is located within the range of the air guide body 51, which means that the end (end E) of the wind-raising plate 522 is retracted a distance toward the second end (end B) of the air guide body 51 compared to the first end (end A) of the air guide body 51. It can also be understood that when a perpendicular line is drawn from the end (end E) of the wind-raising plate 522 to the first side 511 of the air guide body 51, the foot of the perpendicular line will fall on the first side 511 itself rather than the extended surface of the first side 511. In this way, the section of the air guide body 51 protruding from the wind raising plate 522 can guide and block the ambient air flowing out of the guide channel 516 to a certain extent, so that it can be better mixed with the air supply airflow. In addition, it can also prevent the wind raising plate 522 from contacting the upper edge of the air outlet 12 when the air guide body 51 is closing the air outlet 12.

[0059] In some embodiments, Figure 6 As shown, at the junction of the wind-raising plate 522 and the wind guide plate body 51 (i.e., the extended starting end of the wind-raising plate 522), the angle between the tangent of the wind-raising plate 522 and the tangent of the wind guide plate body 51 is θ. The inventors have found through research that if the angle is too small, the wind-raising effect angle will be insufficient, and if it is too large, the wind direction turning angle will be too large when the air supply airflow flows from the surface of the first side 511 to the surface of the wind-raising plate 522, resulting in excessive wind resistance. The most preferred range of this angle is between 10° and 60°. θ is preferably 25°. In addition, this angle range can also achieve the maximum drainage volume while minimizing the air volume loss of the air conditioner.

[0060] like Figures 3 to 6 As shown, the wind-raising plate 522 can be a flat plate, and its tangent direction is parallel to its plate surface. The wind guide plate body 51 can be an arc-shaped plate with the first side surface 511 being a concave surface and the central axis parallel to the length direction of the wind guide plate body 51.

[0061] In some embodiments, Figure 2 and Figure 3 As shown, each air deflector 50 further includes at least one rotating arm 53, one end of which is connected to the driving device 70 located inside the housing 10, and the other end is connected to the air deflector body 51. Driven by the driving device 70, the rotating arm 53 drives the air deflector body 51 to rotate upward 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 may 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, which is used to directly or indirectly drive the rotating arm 53 to rotate.

[0062] Figure 8 yes Figure 2 The schematic diagram of the state of the wall-mounted air conditioner indoor unit after the air guide plate is further opened is shown. Figure 2 and Figure 8 As shown, the air outlet 12 can be located at the lower front part of the shell 10 and opened toward the front and downward. The rotating arm 53 is a bent arm with a bent opening facing downward. The driving device 70 is installed at the bottom wall of the air duct 40. The purpose of setting the bent arm is: at each angle of the air outlet 12 opened by the air guide plate 50, the first side surface 511 is directed toward the air outlet 12, so that the supply air flow is guided by the first side surface 511, and the second side surface 512 is facing away from the air outlet 12 so that it contacts the ambient air, which is conducive to realizing the air mixing function of the air guide plate 50. Moreover, the setting of the bent arm also facilitates the rotation of the air guide plate body 51 to the bottom of the shell 10 to completely avoid the supply air flow blown out by the air outlet 12, that is, to completely open the air outlet 12 so that the air guide plate 50 does not block the air flow at all.

[0063] On this basis, one or more inner guide plates 80 may be provided at the air outlet 12, and the inner guide plates 80 may be rotatably installed at the air outlet 12 and located on the inner side of the air guide plate 50, so as to adjust the up and down air outlet direction of the air outlet 12. That is, the air guide plate 50 may play a greater role in opening and closing the air outlet and mixing the air, and the inner guide plate 80 may play a role in guiding the air and swinging the air up and down.

[0064] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
