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 and an air guide plate thereof. 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 and an air guide plate thereof that overcome the above-mentioned problems or at least partially solve the above-mentioned problems.

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

[0007] A further object of the present invention is to enhance the air guiding and air mixing effect of the air guide plate.

[0008] In one aspect, the present invention provides an air guide plate for a wall-mounted air conditioner indoor unit, comprising:

[0009] The air guide plate body is used to be installed at the air outlet of the indoor unit of the wall-mounted air conditioner; and

[0010] A plurality of wind-raising portions are arranged at intervals along the length direction of the wind guide plate body;

[0011] Each wind-raising portion is protrudingly arranged on the first side surface of the air guide plate body to define a drainage channel with the first side surface, and an outlet of the drainage channel is formed on the side facing the first end of the air guide plate body, and a plurality of drainage ports penetrating the two side surfaces of the air guide plate body are formed on the air guide plate body, and each drainage port is connected to a drainage channel, and each wind-raising portion is configured such that: when the air guide plate is in a position with the first side surface facing upward and the first end facing forward, the air supply airflow changes its airflow direction when flowing through the wind-raising portion, and negative pressure is formed at the first side surface, so as to drive the ambient air on the other side of the air guide plate body to merge into the air supply airflow through the drainage port and the drainage channel in sequence; and

[0012] In the direction toward the first end of the air guide plate body, the distance between two adjacent air raising portions gradually decreases, so that an acceleration channel for the air supply airflow is formed between the two adjacent air raising portions.

[0013] Optionally, the air deflector body is an arc-shaped plate with a first side surface being concave and a central axis being parallel to a length direction of the air deflector body; and assuming that the arc of the air deflector body section between any position of the acceleration channel and the inlet position of the acceleration channel is θ, the width L of the acceleration channel at this position satisfies: L = aθ 2 +bθ+c, where a, b, c are preset constants.

[0014] Optionally, the ratio of the inlet width to the outlet width of the accelerating channel is between 1.3 and 2.

[0015] Optionally, each wind-raising portion includes: a wind-raising plate, which extends from the first side surface toward the first end of the wind guide plate body and gradually away from the first side surface; and two side plates, which extend from two side edges of the wind-raising plate toward the first side surface and away from each other, and are connected to the first side surface, so that an acceleration channel is formed between the two adjacent side plates of the two adjacent wind-raising portions.

[0016] 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 30°.

[0017] Optionally, a projection of the wind-raising portion on the first side surface completely covers the drainage port.

[0018] Optionally, a projection of the wind-raising portion on the first side surface is located within the range of the wind guide plate body.

[0019] On the other hand, the present invention also provides a wall-mounted air conditioner indoor unit, comprising:

[0020] A housing having an air outlet; and

[0021] At least one wind deflector, which is the wind deflector according to any of the above items, and the wind deflector body is installed at the air outlet.

[0022] Optionally, there are multiple air guide plates, which are arranged along the length direction of the shell.

[0023] 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.

[0024] In the air guide plate of the present invention, a plurality of wind-raising parts and drainage holes are provided on the air guide plate body to have a wind mixing function. Specifically, when the supply air flow flows 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 wind mixing 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.

[0025] Furthermore, in the air guide plate of the present invention, the distance between two adjacent wind-raising parts gradually decreases in the direction toward the first end of the air guide plate body, so that an acceleration channel for the air supply airflow is formed between the two adjacent wind-raising parts. The air supply airflow flowing through the acceleration channel gradually increases in velocity, and passes through the areas on both sides of the outlet of the drainage channel at a faster speed, thereby forming a negative pressure area with lower air pressure on both sides of the outlet of the drainage channel (the greater the flow velocity, the lower the air pressure), thereby being able to attract the ambient air flowing out of the drainage channel to mix with the part of the air supply airflow, so that the overall mixed air volume of the air guide plate is larger.

[0026] Furthermore, in the wind guide plate of the present invention, the wind raising portion 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 raised and blown out 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.

[0027] Furthermore, 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 of which is independently controlled, and the air guide angles do not affect each other. For example, the left air guide plate can be made to supply air upward to the area it covers, the middle air guide plate can be made to supply air forward, and the right air guide plate can be made to supply air downward to the area it covers, so that the air outlet can blow out multiple airflows of different heights at the same time. In this way, the zoning adjustment of the air supply airflow is realized, the different needs of users in different areas of the room are met, and the air supply control of the air conditioner is made more refined.

[0039] Figure 1 is a schematic structural diagram of an air guide plate according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of a second side view of the air deflector shown; Figure 3 yes Figure 1 NN sectional view of the wind deflector shown; Figure 4 yes Figure 1 A schematic diagram of a first side view of the air deflector shown; Figure 5 Schematic diagram of the acceleration channel shape of the air guide plate. In each figure, the wind direction of the air supply airflow is indicated by a solid arrow, and the direction of the ambient air inflow is indicated by a hollow arrow.

[0040] like Figures 1 to 5 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 shell 10 of the wall-mounted air-conditioning indoor unit. 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 air flow. 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 guide plate body 51 is in the shape of a long strip, which has two side surfaces (two surfaces 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 1 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 1 The two ends in the y-axis direction) are respectively the first end (end A) and the second end (end B).

[0041] A plurality of wind-raising portions 52 are arranged at intervals along the length direction of the wind deflector body 51. Each wind-raising portion 52 is protrudingly disposed on the first side surface 511 of the wind deflector body 51 to define a drainage channel 516 with the first side surface 511 of the wind deflector body 51. In addition, an outlet 5161 of the drainage channel 516 is formed on the side of the wind-raising portion 52 facing the first end (end A) of the wind deflector body 51. Figure 3 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 .

[0042] Each wind-raising portion 52 is configured such that: when the air 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-back direction), the air supply airflow blown out from the air outlet 12 changes its airflow direction when flowing through the air-raising portion 52, and forms a negative pressure 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) through the drainage port 515 and the drainage channel 516, and then flows out from the outlet of the drainage channel 516 and merges into the air supply airflow, as shown in FIG. Figure 3 and Figure 8 .

[0043] 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 3The 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.

[0044] 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. The wind raising part 52 and the air guide plate body 51 can be an integral part made by an integrated molding process to simplify the manufacturing process.

[0045] Furthermore, if Figure 4 As shown in FIG. 1 , in the direction toward the first end (end A) of the air guide body 51, the distance between the two adjacent wind-raising portions 52 gradually decreases, so that an acceleration channel 517 for the air supply airflow is formed between the two adjacent wind-raising portions 52. The flow rate of the air supply airflow flowing through the acceleration channel 517 gradually increases, and passes through the two side areas ( Figure 4 Arrows are used to indicate the general direction of the airflow through the acceleration channel 517, indicating the acceleration situation), thereby forming a negative pressure area with lower air pressure on both sides of the outlet of the drainage channel 516 (the greater the flow rate, the lower the air pressure), thereby attracting the ambient air flowing out of the drainage channel 516 to mix with this part of the supply air flow, making the overall mixed air volume of the air guide plate 50 larger.

[0046] The inventors found that if Figure 5 As shown, the inlet width L of the acceleration channel 517 is 0 With outlet width L 1 The ratio is set between 1.3 and 2 (including the end points) to obtain the best acceleration and air mixing effect. Figure 5 C 0 Location, exit location is C 1 The width direction of the acceleration channel 517 is parallel to the length direction of the air guide plate body 51. The width value of a certain position of the acceleration channel 517 specifically refers to: a straight line passing through a point in the acceleration channel and on the first side surface and parallel to the length direction of the air guide plate body, and the distance between the intersection of the straight line and the two adjacent wind-raising parts.

[0047] like Figure 5As shown, the air guide body 51 may be an arc-shaped plate with the first side surface 511 being concave and the central axis being parallel to the length direction of the air guide body 51. Assume that any position C of the acceleration channel 517 is parallel to the inlet position C of the acceleration channel 517. 0 The arc of the air guide plate body section between is θ, and the width of the acceleration channel at this position is L. In some embodiments, the above parameters can satisfy: L = aθ 2 +bθ+c, where a, b, c are preset constants and θ is the radian value. When θ=0, L is the acceleration channel inlet width, i.e. L=L 0 , those skilled in the art can determine reasonable values ​​of a, b, and c based on the above relationship and further through experiments or theoretical calculations.

[0048] The air guide plate of the present invention enables the indoor unit of a wall-mounted air conditioner to 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 indoor unit of a wall-mounted air conditioner is cooling, it is usually desired that the air guide plate guides the cold air to blow out as vertically upward as possible. However, when the air guide plate of a 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 8 ), 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.

[0049] 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.

[0050] In some embodiments, Figure 1As shown, the wind-raising portion 52 includes a wind-raising plate 522 and two side plates 523. The wind-raising plate 522 starts from the first side surface 511 and extends toward the first end (end A) of the air 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 away from each other, and are sealed and connected to the first side surface 511. That is, in the direction from the two side edges of the wind-raising plate 522 to the first side surface 511, the spacing between the two side plates 523 is gradually increased. This design is to form the aforementioned acceleration channel 517 between the two adjacent side plates 523 of the two adjacent wind-raising portions 52. On the one hand, the air supply airflow flowing out of the acceleration channel 517 can be used for air mixing. On the other hand, the airflow guided by the wind-raising plate 522 forms a negative pressure at the upper edge of the outlet 5161 of the guide channel 516 to attract 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.

[0051] In some embodiments, Figure 3 As shown, the projection of the wind-raising plate 522 on the first side 511 can completely cover the air outlet 515. And it is 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 can also be located within the range of the air guide body 51, which specifically 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 a vertical 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, and the foot of the vertical 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.

[0052] In some embodiments, Figure 3 As shown, at the junction of the wind raising plate 522 and the wind guide plate body 51 (i.e., the extension start end of the wind raising plate 522), the angle between the tangent line of the wind raising plate 522 and the tangent line of the wind guide plate body 51 is θ 1The inventor has found that if the angle is too small, the wind lifting effect 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 surface 511 to the surface of the wind lifting plate 522, resulting in excessive wind resistance. The most preferred range of this angle is between 10° and 30°. 1 The preferred angle is 25°. In addition, this angle range can also achieve the maximum drainage volume while minimizing the air loss of air conditioning. Figures 1 to 3 As shown, the wind-raising plate 522 can be a flat plate, and its tangent direction is parallel to its plate surface.

[0053] The invention also provides a wall-mounted air-conditioner indoor unit. Figure 6 is a schematic diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention when three air guide plates are in a closed state; Figure 7 yes Figure 6 The schematic diagram of the wall-mounted air conditioner indoor unit shown is when three air guide plates guide air at different air guide angles; Figure 8 yes Figure 6 A schematic cross-sectional view of a wall-mounted air conditioner indoor unit is shown; Fig. 9 yes Figure 8 The schematic diagram shows the state of the indoor unit of the wall-mounted air conditioner after the air guide plate is further opened.

[0054] like Figures 6 to 9 As shown, the wall-mounted air conditioner indoor unit of the embodiment of the present invention may generally include a housing 10 and at least one air guide plate 50 of any of the above embodiments. The housing 10 is provided with an air inlet 11 and an air outlet 12. The air guide plate body 51 of the air guide plate 50 is movably installed at the air outlet 12.

[0055] For example Figure 6 and Figure 7 As shown, the number of the air guide plates 50 can be multiple, and the multiple air guide plates 50 are arranged along the length direction of the housing 10 (i.e. Figure 1 For example, the number of the air guide plates 50 may be three, such as Figure 6 and Figure 7 The number of the air guide plates 50 may also be two, four or more.

[0056] Can be as Figure 6 and Figure 7 As shown, multiple air guide plates 50 are arranged at one air outlet 12. That is, one air outlet 12 corresponds to multiple air guide plates 50. In some alternative solutions, multiple air outlets may also be arranged, so that each air outlet corresponds to one air guide plate, or each air guide plate corresponds to multiple air outlets.

[0057] 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, and the air guide angles do not affect each other. For example, as shown in Figure 7, the upward air supply angle of the left air guide plate can be the largest, followed by the middle, and the right air guide plate can be biased downward to supply air, so that the air outlet can blow out multiple airflows of different heights at the same time. In this way, the zoning adjustment of the air supply airflow is realized to meet the different needs of users in different areas of the room, making the air supply control of the air conditioner more refined.

[0058] The wind 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 provided to detect the area where the human body is located, the surface temperature and other information, so that the controller obtains the detection information and controls the wind guide plate corresponding to the area according to a preset program, so as to achieve the air supply effects such as the air supply airflow directly blowing on the human body or avoiding the human body.

[0059] In some embodiments, Figure 8 and Fig. 9 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.

[0060] like Fig. 9 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.

[0061] 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.

[0062] 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.
