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] 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, each wind-raising portion is protrudingly arranged on the first side surface of the wind guide plate body to define a drainage channel with the first side surface, and an outlet of the drainage channel is formed on a side of the wind guide plate body facing the first end of the wind guide plate body, and a plurality of drainage ports penetrating two sides of the wind guide plate body are formed on the wind guide plate 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, the 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] 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 part 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 part and the first side to blow out downward.

[0021] 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.

[0022] 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.

[0023] 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 direction of the wind guide plate body and gradually away from the first side surface. When the wind guide plate is in the upward blowing position, 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 (the angle between the upward air outlet direction and the vertical direction) of the air supply airflow smaller, so as to better avoid the human body.

[0024] Furthermore, in the wind guide plate 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 parts (the wind guide plate is in the upward blowing position). 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 wind mixing stronger.

[0025] 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 enters the drainage channel through the outlet of the drainage channel, and then blows downward through the drainage port to form a "feather air flow", which avoids the accumulation of air flow in the drainage channel.

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.

[0036] like Figures 1 to 6As 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).

[0037] 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, 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 4 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 .

[0038] 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) 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, refer to Figure 6 .

[0039] 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 6The 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.

[0040] 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.

[0041] When the air guide plate 50 is in the upward blowing position (such as Figure 6 ), 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 6 ), 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.

[0042] 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.

[0043] 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 1 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 1That 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.

[0044] 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 .

[0045] In some embodiments, Figures 1 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.

[0046] Furthermore, if Figure 5 As 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 (the air guide plate is in the upward blowing position). 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.

[0047] 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 5The 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.

[0048] like Figure 5 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.

[0049] In some embodiments, Figure 4 As 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.

[0050] In some embodiments, Figure 4As 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.

[0051] like Figures 1 to 4 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.

[0052] The invention also provides a wall-mounted air-conditioner indoor unit. Figure 7 yes Figure 6 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.

[0053] like Figure 6 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.

[0054] like Figure 6 As 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.

[0055] 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.

[0056] For example, the air guide plate 50 can be moved to an upward blowing position below the air flow, with the first side surface 511 facing upward and the first end (end A) facing forward, so that the air flow is guided by the first side surface 511 and the wind-raising portion 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.

[0057] The air guide plate 50 can be moved to a downward blowing position in front of the air flow, with the first side surface 511 facing backward and the first end (end A) facing upward, so that the air flow is guided by the wind raising portion 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 flowing into the wind-raising plate 522 enters the drainage channel 516 through the outlet of the drainage channel 516, and then blows downward through the drainage port 515 to form a "feather airflow", thereby avoiding the accumulation of airflow between the wind-raising plate 522 and the air guide plate body 51.

[0058] 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.
