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] The object of the present invention is to provide a wall-mounted air conditioner indoor unit and an air guide plate thereof that overcomes the above-mentioned problems or at least partially solves the above-mentioned 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 air guide plate to have a wind-raising function so as to achieve the upward blowing of cold air.

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

[0009] An air guide plate body, which is used to be installed at the air outlet of the indoor unit of the wall-mounted air conditioner, and is provided with an air guide port that runs through the first side surface and the second side surface; and

[0010] The wind-raising plate 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 the starting end is closer to the second end of the wind guide plate body relative to the air guide port, so that when the wind 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 plate, and forms a negative pressure at the first side surface, so as to drive the ambient air on the other side of the wind guide plate body to merge into the air supply airflow through the air guide port; and

[0011] The wind-raising plate is provided with an overflow port to allow part of the ambient air to flow into the supply air flow through the inlet port and the overflow port in sequence.

[0012] Optionally, the end of the wind-raising plate exceeds the drainage port to define a drainage channel connected to the drainage port with the first side surface.

[0013] Optionally, the drainage port is cylindrical and gradually extends obliquely toward the first end from the first side to the second side; or the drainage port is truncated cone-shaped and extends with a gradually decreasing inner diameter from the first side to the second side.

[0014] Optionally, the wind guide plate further includes: a plurality of connecting ribs, which are arranged at intervals along the length direction of the wind guide plate body, and each connecting rib connects the wind lifting plate and the wind guide plate body.

[0015] Optionally, the projection of the wind-raising plate on the first side is located within the range of the wind guide plate body.

[0016] Optionally, the air guide plate body is an arc-shaped plate with a concave first side surface and a central axis parallel to the length direction of the air guide plate body; the wind lifting plate is an arc-shaped plate with a central axis parallel to the central axis of the air guide plate body and a convex surface facing the air guide plate body; and the angle between the tangent at the first end position of the air guide plate body and the tangent at the end position of the wind lifting plate is between 25° and 35°.

[0017] Optionally, there is one wind-raising plate, and its two ends in the length direction are close to the two ends in the length direction of the wind guide plate body; or there are multiple wind-raising plates, and the multiple wind-raising plates are arranged at intervals along the length direction of the wind guide plate body.

[0018] Optionally, each wind-raising plate corresponds to a drainage port; each drainage port is a single opening; or each drainage port includes a plurality of sub-drainage ports arranged at intervals.

[0019] On the other hand, the present invention also provides a wall-mounted air-conditioning indoor unit, comprising: a shell having an air outlet; and an air guide plate, which is the air guide plate according to any of the above items, and the air guide plate body is installed at the air outlet.

[0020] Optionally, the wall-mounted air conditioner indoor unit is configured to: move the air guide plate to an upward blowing position below the supply air flow, with the first side facing upward and the first end facing forward, so that the supply air flow is guided by the first side and the wind lifting plate to blow out upward; or move the air guide plate to a downward blowing position in front of the supply air flow, with the first side facing backward and the first end facing upward, so that the supply air flow is guided by the wind lifting plate and the first side to blow out downward.

[0021] The air guide plate of the present invention has an air mixing function. When the supply air flow passes through the first side surface of the air guide plate body, the wind lifting plate 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 of the air guide plate body, 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 opened 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.

[0022] In addition, after the ambient air enters the inlet, part of it will flow into the supply air flow through the flow holes on the wind-raising plate, which further increases the mixed air volume.

[0023] The present invention realizes the air mixing function by only opening the air guide plate body and adding an air lifting plate, which is very clever in design, very simple in structure and low in cost. Moreover, other structures of the indoor unit of the wall-mounted air conditioner do not need to be modified, which is very conducive to mass production and promotion.

[0024] Furthermore, when the wind guide plate of the present invention is guiding the wind, the supply air flow can be blown upward under the action of the wind lifting plate, which not only generates a negative pressure area, but also makes the upward blowing angle of the supply air flow (the angle between the upward wind outlet direction and the vertical direction) smaller, so as to better avoid the human body.

[0025] Furthermore, the wind guide plate of the present invention makes the end of the wind lifting plate along the air flow direction extend beyond the drainage port, so as to define a drainage channel connected to the drainage port with the first side surface, which can guide the flow direction of the ambient air to make the angle between it and the supply air flow smaller, making the mixing of the two softer, and avoiding the ambient air directly passing through the drainage port and vertically entering the supply air flow, causing problems such as excessive noise.

[0026] Furthermore, the wall-mounted air conditioner indoor unit of the present invention enables the air guide plate to have an upward blowing position and a downward blowing position. When the air conditioner is cooling, the air guide plate can be adjusted to the upward blowing position, and the supply air flow is blown upward by the first side of the air guide plate body and mixed with the ambient air. The low-temperature supply air flow reaches the highest point and then scatters downward, achieving a "shower-like" cooling experience. When the air conditioner is heating, the air guide plate can be adjusted to the downward blowing position, and the supply air flow is guided nearly vertically downward by the first side of the air guide plate body to reach the bottom surface, achieving a heating and warming experience. In addition, a small amount of supply air flow that flows into the space between the wind-raising plate and the air guide plate body can also be blown downward through the drainage port to form a "feather air flow", thereby avoiding the accumulation of air flow between the wind-raising plate and the air guide plate body.

[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 An enlarged view of the M position of the air guide plate shown; Figure 3 yes Figure 1Another perspective schematic diagram of the air guide plate shown; Figure 4 yes Figure 1 A cross-sectional view of the wind deflector shown; Figure 5 The wall-mounted air conditioner indoor unit of one embodiment of the present invention is a schematic diagram when the air guide plate is in the upward blowing position. 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 one or more wind lifting plates 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. The function of the air guide plate 50 is to open and close the air outlet 12, and it can also be used to adjust the air outlet angle of the air outlet 12. The air flow blown out from the inside of the housing 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, a first side surface 511 and a second side surface 512. The two ends of the air guide plate body 51 in the width direction are the first end (end A) and the second end (end B). The air guide plate body 51 is provided with a flow outlet 515 that passes through the first side surface 511 and the second side surface 512.

[0041] The wind-raising plate 52 starts from the first side surface 511, extends toward the first end (end A) of the air guide plate body 51 and gradually away from the first side surface 511, and the starting end is closer to the second end (end B) of the air guide plate body 51 relative to the air inlet 515. 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 and rear directions), the supply air flow blown out from the air outlet 12 changes its airflow direction when flowing through the wind-raising plate 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) to merge into the supply air flow through the air inlet 515, refer to Figure 5 .

[0042] That is to say, under the guidance of the wind-raising plate 52, the air supply airflow gradually moves away from the first side surface 511, which makes the airflow density at the first side surface 511 of the air guide plate body 51 smaller, forming a negative pressure area ( Figure 5The S1 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.

[0043] like Figures 1 to 5 As shown, the wind-raising plate 52 is provided with a flow port 525 to allow part of the ambient air to flow into the supply air flow through the inlet 515 and the flow port 525 in sequence. That is, due to the high flow velocity on the surface of the wind-raising plate 52, the air pressure is lower than the internal air pressure of the flow port 525, forming a negative pressure area S2. After the ambient air enters the inlet 515, part of it will flow into the supply air flow through the flow port 525, which further increases the mixed air volume.

[0044] For example, the ratio of the width of the flow opening 525 to the width of the wind-raising plate 52 (the distance from the starting end to the end thereof) can be between 1 / 3 and 1 / 2 to prevent the flow opening from being too large and affecting the wind-raising effect. The flow opening 525 can be arranged at the half near the starting end of the wind-raising plate 52 so as to be directly opposite to the guide opening 515, so as to facilitate the ambient air to enter the flow opening 525 from the guide opening 515.

[0045] The present invention realizes the air mixing function by only opening an opening on the air guide plate 50 and adding a wind raising plate 52. The design is very clever, the structure is very simple, and the cost is low. Moreover, other structures of the wall-mounted air conditioner indoor unit do not need to be modified, which is very conducive to mass production and promotion.

[0046] When the air guide plate 50 is in the upward blowing position (such as Figure 5 ), the wall-mounted air conditioner indoor unit 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 cooling, it is usually hoped that the air guide plate will guide the cold air to blow out as vertically upward as possible. However, when the air guide plate of the traditional 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 (reference Figure 5 ), 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.

[0047] In the embodiment of the present invention, the wind lifting plate 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 wind 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 wind 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.

[0048] like Figure 4 As shown, the end (end E) of the wind-raising plate 52 can be made to exceed the air inlet 515 (referring to the end D that exceeds the air inlet 515 and is close to the first end of the air guide body 51), so as to define a flow channel 516 connected to the air inlet 515 with the first side surface 511. The flow channel 516 can guide the flow direction of the ambient air, so that when the ambient air merges with the supply air flow, the angle between the two air flows is smaller and the mixing is softer.

[0049] The projection of the wind-raising plate 52 on the first side surface 511 can be located within the range of the wind guide plate body 51. In other words, the end (end E) of the wind-raising plate 52 is retracted a distance toward the second end (end B) of the wind guide plate body compared to the first end (end A) of the wind guide plate body 51. It can also be understood that when a vertical line is drawn from the end (end E) of the wind-raising plate 52 to the first side surface 511 of the wind guide plate body 51, the foot of the vertical line will fall on the first side surface 511 itself rather than the extended surface of the first side surface 511. In this way, the section of the wind guide plate body 51 protruding from the wind-raising plate 52 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 supply air flow. In addition, it can also avoid that the wind-raising plate 52 contacts the upper edge of the air outlet 12 when the air guide plate body 51 closes the air outlet 12.

[0050] In some alternative embodiments, the wind-raising plate 52 may not completely cover the air outlet 515 .

[0051] like Figures 1 to 3 As shown, the air guide plate 50 also includes a plurality of air guide plates along the length direction of the air guide plate body 51 (parallel to Figure 1 The connecting ribs 522 are arranged at intervals (in the x-axis direction), and each connecting rib 522 connects the wind-raising plate 52 and the wind-guiding plate body 51 to achieve structural connection. In addition, the connecting ribs 522 divide the drainage channel 516 into a plurality of sub-channels, splitting the ambient air to make the airflow softer. The wind-raising plate 52, the connecting ribs 522 and the wind-guiding plate body 51 can be formed as an integral piece for easy processing and manufacturing.

[0052] Two of the multiple connecting ribs 522 can be connected between the two ends of the wind-raising plate 52 along the length direction of the wind guide plate body 51 and the first side surface 511 to close the gap between the two ends of the wind-raising plate 52 and the first side surface 511, thereby preventing the airflow from flowing along the length direction of the wind guide plate body 51, thereby avoiding the occurrence of adverse vortices and noise.

[0053] like Figures 1 to 4 As shown, the air guide body 51 can be installed on the air outlet 12 so as to extend horizontally in the length direction. The air guide body 51 can 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, and the wind-raising plate 52 is an arc-shaped plate with the central axis being parallel to the central axis of the air guide body 51 and the convex surface facing the air guide body 51, so as to better guide the air flow upward.

[0054] The angle between the tangent line (tangent line of the arc surface) at the first end (end A) of the air guide body 51 and the tangent line (tangent line of the arc surface) at the end (end E) of the wind-raising plate 52 is θ. The inventors have found 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 surface 511 to the surface of the wind-raising plate 52, resulting in excessive wind resistance. The most preferred range of the angle is between 25° and 35°. θ is preferably 30°.

[0055] Figure 7 is a schematic structural diagram of an air guide plate according to another embodiment of the present invention; Figure 8 yes Figure 7 An enlarged view of position N of the air guide plate shown; Fig. 9 yes Figure 7 Another perspective schematic diagram of the air guide plate shown; Fig.10 yes Figure 7 A cross-sectional view of the air deflector shown.

[0056] Figures 7 to 9 The wind deflector of the embodiment shown is Figures 1 to 6 The main differences between the air guide plates of the illustrated embodiments are the shape of the air guide opening, the number of air raising plates and the structure of the air guide opening.

[0057] The air guide port 515 may be cylindrical and gradually extend from the first side surface 511 to the second side surface 512 toward the first end (end A) of the air guide plate body 51. Figure 4 , which makes the flow direction of the ambient air flowing in through the flow port 525 and the flow direction of the supply air flow form an obtuse angle, which makes the two air flows flow in opposite directions, and the mixing effect is stronger.

[0058] Or, if Fig.10As shown, the air inlet 515 may also be truncated cone-shaped and extend with a gradually decreasing inner diameter from the first side 511 to the second side 512. That is, along the flow direction of the ambient air, the air inlet gradually expands, which helps the ambient air to mix more smoothly into the supply air flow.

[0059] like Figures 1 to 4 As shown, there is one wind-raising plate 52, which is also in a long strip shape, with both ends of the wind-raising plate 52 in the length direction close to both ends of the wind guide body 51 in the length direction. That is, the length of the wind-raising plate 52 is equal to or substantially equal to the length of the wind guide body 51, so that all parts of the wind guide body 51 in the length direction have wind mixing effect and wind-raising effect.

[0060] Alternatively, the number of the wind-raising plates 52 may be multiple, and the multiple wind-raising plates 52 may be arranged at intervals along the length direction of the wind guide plate body 51. Figures 7 to 10 As shown, two wind-raising plates 52 are provided. The two wind-raising plates 52 can be respectively located on two 1 / 2 sections in the length direction of the wind guide plate body 51. Such a setting can make a partial area of ​​the wind guide plate body 51 perform the wind-raising process, and the interval area between adjacent wind-raising plates 52 does not perform the wind-raising process, so that the wind outlet direction in the vertical direction of the interval area is different from the vertical wind outlet direction where the wind-raising plates 52 are provided, so that the entire wind guide plate forms a staggered wind outlet effect in the vertical direction, expanding the wind outlet range.

[0061] Each wind-raising plate 52 may correspond to one drainage port 515. Each drainage port 515 may be a single opening, such as Figure 1 Alternatively, each drainage port 515 may include a plurality of sub-drainage ports 5151 arranged at intervals, such as Figure 7 , which can make the appearance of the air guide plate 50 more beautiful.

[0062] The invention also provides a wall-mounted air-conditioner indoor unit. Figure 5 is a schematic diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention when the air guide plate is in an upward blowing position; Figure 6 yes Figure 4 The schematic diagram of the state of the indoor unit of the wall-mounted air conditioner is shown when the air guide plate is in the downward blowing position.

[0063] like Figure 5 As shown, the wall-mounted air conditioner indoor unit of the embodiment of the present invention may generally include a housing 10 and an air guide plate 50 of any of the above embodiments. The housing 10 is provided with an air inlet (not shown) and an air outlet 12. The air guide plate body 51 of the air guide plate 50 is movably mounted at the air outlet 12.

[0064] like Figure 5As shown, the wall-mounted air conditioner indoor unit may include an evaporator (not shown), a fan 30, and an air duct 40. The evaporator is used to perform heat exchange with the air entering the housing 10 from the air inlet to form a supply air flow (specifically, cold air during cooling and hot air during heating). The inlet of the air duct 40 faces the evaporator, 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 the air to flow from the evaporator to the air outlet 12. The air duct 40 may be as shown in FIG. Figure 5 The end diffuser air duct shown in the figure can achieve low pressure loss and large air volume.

[0065] In some embodiments, the deflector body 51 can be made to rotate around a fixed axis parallel to its length direction (i.e., rotate around a fixed axis) to open and close the air outlet 12 and guide the air outlet direction of the air outlet 12. Alternatively, the deflector body 51 can also be made to perform planar motion, i.e., a composite motion combining rotation and translation, so that the deflector body 51 has more adjustment positions. A driving mechanism can be provided in the housing 10, and the driving mechanism includes a motor and a motion mechanism. A rotating arm can be connected to the deflector body 51, and the rotating arm is connected to the driving mechanism to drive the deflector body 51 to achieve the aforementioned planar motion. The driving mechanism that can drive an object to achieve planar motion (translation + rotation) is relatively common in the prior art and will not be described in detail here.

[0066] For example, the air guide plate 50 can be moved to an upward blowing position below the air supply flow, with the first side surface 511 facing upward and the first end (end A) facing forward, so that the air supply flow is guided by the first side surface 511 and the air lifting plate 52 to blow upward. Figure 5 For example, when the air conditioner is cooling, the air guide plate 50 can be adjusted to the aforementioned upward blowing position, and the first side surface 511 of the air guide plate body 51 blows the supply air flow upward and mixes with the ambient air. The low-temperature supply air flow reaches the highest point and then scatters downward, achieving a "shower-style" cooling experience.

[0067] The air guide plate 50 can be moved to a downward blowing position in front of the air supply flow, with the first side surface 511 facing backward and the first end (end A) facing upward, so that the air supply flow is guided by the air raising plate 52 and the first side surface 511 to blow downward. Figure 6 For example, when the air conditioner is heating, the air guide plate 50 can be adjusted to the downward blowing position, and the first side surface 511 of the air guide plate body 51 guides the air supply airflow nearly vertically downward to the bottom surface, thereby achieving a heating and foot-warming experience. In addition, a small amount of air supply airflow flowing between the wind raising plate 52 and the air guide plate body 51 can also be blown downward through the air inlet 515 to form a "feather airflow", thereby avoiding the accumulation of airflow between the wind raising plate 52 and the air guide plate body 51.

[0068] 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.
