Description

Technical Field

[0001] The invention relates to the 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 realize the upward blowing of the air supply air flow and to increase the diffusion angle of the air supply air flow in the left and right directions.

[0007] A further object of the present invention is to enable the air guide plate to have the function of guiding and mixing air, so as to make the air supply flow more comfortable.

[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 so as to be rotatable around an axis parallel to its own length direction;

[0010] Two wind-raising portions are arranged at intervals along the length direction of the wind guide body, each wind-raising portion protrudes from a first side surface of the wind guide body that faces upward when the air outlet is opened, and is configured to guide the air supply air flow to gradually move away from the wind guide body to flow obliquely upward when the air supply air flow flows through the first side surface; and

[0011] A plurality of guide ribs protrude from the first side surface and are arranged between the two wind-raising portions along the length direction of the air guide plate body, and are configured to guide the air supply airflow to gradually deflect toward the two ends of the length direction of the air guide plate body.

[0012] Optionally, two through-going drainage ports are provided on the air guide plate body, each of which is located on the downstream side of the air flow at the connection between a wind-raising portion and the air guide plate body, so that when the supply air flow gradually flows away from the air guide plate body, the ambient air on the other side of the air guide plate body is driven to merge into the supply air flow through the drainage port.

[0013] Optionally, the wind raising portion includes a wind raising plate which gradually moves away from the first side surface along the airflow direction from an upstream edge of the airflow guide port.

[0014] Optionally, the end of the wind-raising plate along the airflow direction exceeds the drainage port to define a drainage channel connected to the drainage port with the first side surface.

[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 wind-raising portion further includes a plurality of connecting ribs arranged at intervals in a direction parallel to the rotation axis of the wind guide plate body, and each connecting rib connects the wind-raising plate and the wind guide plate body.

[0017] Optionally, the wind-raising plate is an arc-shaped plate whose central axis is parallel to the rotation axis of the wind guide plate body and whose convex surface faces the wind guide plate body.

[0018] Optionally, the multiple guide ribs include a plurality of first guide ribs and a plurality of second guide ribs arranged in sequence along the length direction of the air guide plate body; the first guide ribs and the second guide ribs extend toward the downstream direction of the air supply air flow and gradually deviate toward both ends of the length direction of the air guide plate body.

[0019] Optionally, the plurality of guide ribs further include a third guide rib, which is located between the plurality of first guide ribs and the plurality of second guide ribs, and whose extension direction is perpendicular to the length direction of the air guide plate body.

[0020] 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, wherein the air guide plate body is rotatably installed at the air outlet.

[0021] Optionally, the air guide plate also includes at least one rotating arm, one end of which 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.

[0022] The air guide plate of the present invention can better lift and blow out the air supply airflow, and increase the diffusion angle of the air supply airflow in the left and right directions, and the design is very clever. Specifically, when the air supply airflow flows through the first side surface of the air guide plate body facing upward, the wind lifting part changes the flow direction of the air supply airflow, so that the air supply airflow gradually moves away from the air guide plate body and flows upward, that is, it is lifted and blown out. Since a special wind lifting part is provided, the wind lifting angle can be designed to be larger, so that the wind direction is closer to vertical upward, which fully meets the requirements for the upward angle in the air conditioning cooling or non-blowing mode.

[0023] Furthermore, when the air guide plate is in the air guiding state and the air supply airflow flowing out of the air outlet flows through the first side surface, the multiple air guide ribs guide the air supply airflow to gradually deflect toward the two ends of the length direction of the air guide plate body, that is, gradually diffuse to the two sides of the length direction of the air guide plate body. In this way, the diffusion angle of the air outlet in the left and right directions is increased, and wide-angle air supply is achieved, making the temperature inside the room more uniform and the human body feel more comfortable.

[0024] Moreover, since multiple guide ribs are arranged between the two wind-raising parts, the left and right sections of the wind guide plate raise the wind upward, guiding the wind higher and farther. The middle section supplies air at a wide angle, guiding the wind at a relatively low angle but at a wider angle. The air supply airflows of different length sections of the wind guide plate are staggered in the up, down, left and right directions, achieving a multi-dimensional three-dimensional air outlet effect, with a more dispersed airflow and higher comfort.

[0025] Furthermore, the air guide plate of the present invention also 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 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 of the air guide plate body, forming a negative pressure. Under the attraction of the negative pressure area, the ambient air on the second side of the air guide plate body enters the negative pressure area through the inlet 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, which makes the supply air flow more comfortable.

[0026] Furthermore, the present invention realizes the air mixing function by only opening a drainage port on the air guide plate body and adding a wind raising part, which is very clever in design, very simple in structure and low in cost. 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.

[0027] 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.

[0028] Based on the following detailed description of specific embodiments of the present invention in conjunction with the accompanying drawings, those skilled in the art will become more aware of the above and other objects, advantages and features of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Hereinafter, some specific embodiments of the present invention will be described in detail in an exemplary and non-limiting manner with reference to the accompanying drawings. The same reference numerals in the accompanying drawings indicate the same or similar components or parts. It should be understood by those skilled in the art that these drawings are not necessarily drawn to scale. In the accompanying drawings:

[0034] 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 Another perspective schematic diagram of the air guide plate shown; Figure 3 yes Figure 1 NN section view of the wind deflector shown, compared Figure 1 Amplification was performed; Figure 4 Schematic diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention. The x-axis is the central axis of the air guide body, and the y-axis is parallel to the width direction of the air guide body. The solid arrow indicates the wind direction of the air supply airflow, and the hollow arrow indicates the direction of the ambient air inflow.

[0035] like Figures 1 to 4 As shown, the wind deflector 50 of the embodiment of the present invention may generally include a wind deflector body 51 , two wind-raising portions 52 , and a plurality of guide ribs 541 , 542 , 543 .

[0036] The air deflector body 51 is used to be rotatably mounted at the air outlet 12 of the housing 10 of the wall-mounted air conditioner indoor unit. The air deflector body 51 is in the shape of an elongated strip as a whole, and has a length direction and a width direction. The rotation axis x of the air deflector body 51 is parallel to the length direction of the air deflector body 51. The air deflector body 51 is used to open or close the air outlet 12, and to adjust the air outlet angle of the air outlet 12.

[0037] For example Figures 1 to 4 As shown, the air guide plate body 51 can be installed on the air outlet 12 with its rotation axis horizontally or nearly horizontally, so that its length direction is parallel to the left-right direction, so as to adjust the up and down air outlet angles of the air outlet 12.

[0038] 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. When the air outlet 12 is opened, the upward side of the air guide plate body 51 is the first side, and its surface is the first side 511; the downward side is the second side, and its surface is the second side 512. The end of the air guide plate body 51 close to the upstream of the supply air flow when the air outlet 12 is opened is defined as the windward end (end B), and the end close to the downstream of the supply air flow is defined as the outlet end (end A). The flow direction of the supply air flow on the first side 511 of the air guide plate body 51 is toward the outlet end.

[0039] The two wind-raising portions 52 are arranged at intervals along the length direction of the air guide plate body 51. The wind-raising portions 52 are protrudingly arranged on the first side surface 511 of the air guide plate body 51 facing upward when the air outlet 12 is opened, and are configured to guide the air supply air flow to gradually move away from the air guide plate body 51 when the air supply air flow flows through the first side surface 511, so as to gradually deflect upward flow, which can make the wind direction closer to vertical upward, so that the wall-mounted air conditioner indoor unit can achieve better upward blowing, so that the wind can better avoid the human body.

[0040] When the indoor unit of the wall-mounted air conditioner is cooling, blowing the wind upward is conducive to achieving faster and more uniform cooling of the room, and the air supply distance is farther. In addition, blowing the cold or hot air upward can also make the wind avoid the human body to avoid discomfort caused by direct blowing on the human body. In the embodiment of the present invention, since a special wind-raising plate is provided, the designer can design the wind-raising angle to be larger to fully meet the requirements of the air conditioner for the upward angle. The present invention realizes the wind-raising function by only adding a wind-raising portion 52 to the air guide plate 50. The design is very clever, the structure is very simple, and the cost is low. Moreover, the other structures of the indoor unit of the wall-mounted air conditioner do not need to be changed, which is very conducive to mass production and promotion.

[0041] The plurality of guide ribs 541, 542, 543 protrude from the first side surface 511 and are arranged between the two wind-raising portions 52 along the length direction of the air guide body 51 at intervals, and are configured to guide the air supply flow to gradually deflect toward both ends of the length direction of the air guide body 51 when the air supply flow passes through the first side surface 511. That is, the plurality of guide ribs 541, 542, 543 guide a portion of the air supply flow to deflect to the left, and a portion of the air supply flow to deflect to the right, such as Figure 1 The plurality of guide ribs and the air guide plate body 51 may be an integral part made by an integral molding process, such as integral injection molding.

[0042] When the air guide plate of the prior art guides the air, the air supply airflow only flows along the width direction of the air guide plate, so that the airflow is blown out from the air outlet in a nearly parallel manner, forming a rectangular airflow. The air outlet is usually provided with a swing blade inside to adjust the left and right air outlet directions of the air outlet.

[0043] The embodiment of the present invention, by providing a plurality of guide ribs 541, 542, 543 on the air guide body 51, can make at least a portion of the air supply air flow deviate from the width direction of the air guide body 51, so that the portion of the air supply air flow gradually diffuses to the two sides of the length direction of the air guide body 51, that is, diffuses to the left or right, forming a fan-shaped air flow. In this way, the wall-mounted air conditioner indoor unit using the air guide increases the diffusion angle of the air outlet in the left and right directions, and achieves a wide-angle air supply effect, which makes the temperature inside the room more uniform and makes the human body feel more comfortable.

[0044] Moreover, since multiple guide ribs are arranged between the two wind-raising parts, the left and right sections of the wind guide plate raise the wind upward, guiding the wind higher and farther. The middle section supplies air at a wide angle, guiding the wind at a relatively low but wider angle. Based on this, the air supply airflows of different length sections of the wind guide plate are staggered in the up, down, left and right directions, achieving a multi-dimensional three-dimensional air outlet effect, with a more dispersed airflow and higher comfort.

[0045] In some alternative methods, two groups of separately controlled swing blades may be provided on the left and the plurality of swing blades on the right side swing to the right, the air outlet also has a wide-angle air supply effect. However, since the swing blades are located further inside the air outlet relative to the air guide plate, the air supply airflow is not blown out of the air outlet directly after being obliquely guided by the swing blades, but it also hits the surface of the air guide plate to be guided up and down by the air guide plate. However, when the deflected airflow hits the surface of the air guide plate and is guided upward or downward by the air guide plate, its degree of deflection will be significantly attenuated, making it difficult to obtain the desired wide-angle air supply effect.

[0046] In the embodiment of the present invention, the deflection force is directly applied to the air flow by the guide ribs on the air guide plate body 51. After the air flow is deflected, it will be blown out directly from the air outlet 12, and the degree of deflection is not affected by other components.

[0047] In some embodiments, Figures 1 to 4 As shown, two through-flow openings 515 are provided on the air guide body 51, and the air guide openings 515 penetrate two side surfaces of the air guide body 51. Each air guide opening 515 is located at the downstream side of the air flow where a wind-raising portion 52 is connected to the air guide body 51. When the supply air flow gradually flows away from the air guide body 51 through the wind-raising effect of the wind-raising portion 52, a negative pressure is formed at the first side surface 511, thereby driving the ambient air on the second side (i.e., the lower side) of the air guide body 51 to merge into the supply air flow through the air guide opening 515.

[0048] That is, since the wind-raising portion 52 forces the air flow to move away from the first side surface 511, the air flow density at the first side surface 511 of the air guide body 51 becomes smaller, forming a negative pressure area ( Figure 4The 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 air guide plate of the present invention realizes the upward blowing of the air supply air flow and increases the diffusion angle of the air supply air flow in the left and right directions, and also realizes the diversion and mixing of air. The function is very powerful and the design is very ingenious.

[0050] In some embodiments, each wind-raising portion 52 may include a wind-raising plate 521 that gradually moves away from the first side 511 along the airflow direction from the upstream edge (C edge) of the airflow of the air outlet 515. In other words, the wind-raising plate 521 extends from the first side 511, with the extension direction toward the downstream side of the air supply airflow, and gradually moves away from the first side during the extension process. Under the guidance of the wind-raising plate 521, the air supply airflow gradually moves away from the first side 511 of the air guide plate 50, and a negative pressure area is generated at the first side 511. In this embodiment, the starting end of the wind-raising plate 521 is directly connected to the edge of the air outlet 515, so that the connection transition section between the two is smoother, which is conducive to better guiding the airflow.

[0051] like Figure 3 As shown, the projection of the wind-raising plate 521 on the first side 511 can at least cover the air outlet 515, and the wind-raising plate 521 can prevent the ambient air from directly entering the air supply airflow through the air outlet 515 vertically, causing problems such as excessive noise. Furthermore, the end (end E) of the wind-raising plate 521 along the airflow direction can exceed the air outlet 515 (referring to the edge D of the airflow downstream of the air outlet 515), so as to define a drainage channel 516 connected to the air outlet 515 with the first side 511. The drainage channel 516 can guide the flow direction of the ambient air, so that when it merges with the air supply airflow, the angle between the two airflows is smaller, and the mixing is softer.

[0052] The projection of the wind-raising plate 521 on the first side surface 511 can be located within the range of the air guide body 51. In other words, the end (end E) of the wind-raising plate 521 is retracted a distance toward the upstream direction of the air supply airflow compared to the air outlet end (end A) of the air guide body 51. It can also be understood that a vertical line is drawn from the end of the wind-raising plate 521 to the first side surface 511 of the air guide body 51, and 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 air guide body 51 protruding from the wind-raising plate 521 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. It can also prevent the wind-raising plate 521 from contacting the upper edge of the air outlet 12 when the air guide body 51 closes the air outlet 12.

[0053] like Figure 1 and Figure 2 As shown, the wind-raising portion 52 may also include a plurality of connecting ribs 522 arranged at intervals in a direction parallel to the rotation axis of the air guide plate body 51, and each connecting rib 522 connects the wind-raising plate 521 and the air guide plate body 51 to achieve a structural connection. In addition, the connecting ribs 522 can also split the ambient air to make the airflow softer. It can be understood that the connecting ribs 522 are located on the downstream side of the air supply airflow relative to the drainage port 515. In other words, the connecting ribs 522 divide the drainage channel 516 into a plurality of small channels. The wind-raising portion 52 and the air guide plate body 51 can be formed as an integral piece to facilitate processing and manufacturing.

[0054] Two of the plurality of connecting ribs 522 may be connected between the two ends of the wind-raising plate 521 along the rotation axis direction of the wind deflector body 51 and the first side surface 511, so as to close the gap between the two ends of the wind-raising plate 521 and the first side surface 511. In this way, the airflow can be prevented from flowing along the rotation axis direction of the wind deflector body 51, thereby avoiding the occurrence of adverse vortex and noise.

[0055] like Figures 1 to 4 As shown, the wind-raising plate 521 can be a curved plate with a central axis parallel to the rotation axis of the wind guide plate body 51 and a convex surface facing the wind guide plate body 51, so as to better guide the air flow upward. The air guide port 515 can be a long strip with a length direction parallel to the length direction of the wind guide plate body 51, so as to increase the mixed air volume.

[0056] In some alternative embodiments, the wind-raising plate 521 may not completely cover the drainage port 515. Even more, the projection of the wind-raising plate 521 on the first side surface 511 may fall on the upstream area of ​​the drainage port, and not fall on the drainage port 515 at all. Alternatively, the wind-raising portion 52 may be a convex strip protruding from the first side surface 511, and the cross section of the convex strip may be an arc or a triangle. The specific structure will not be described in detail.

[0057] For example Figure 1As shown, the aforementioned plurality of guide ribs may include a plurality of first guide ribs 541 and a plurality of second guide ribs 542 which are sequentially arranged in a spaced order along the length direction of the air guide plate body 51. The first guide ribs 541 and the second guide ribs 542 extend in the downstream direction of the air supply airflow (i.e., from the air inlet end to the air outlet end, the positive direction of the y-axis) and gradually deflect toward the two ends of the length direction of the air guide plate body 51. Please refer to Figure 1 , so that the plurality of first guide ribs 541 extend along the downstream direction of the air supply airflow and deflect to the left, and the plurality of second guide ribs 542 extend along the downstream direction of the air supply airflow and deflect to the right, so that the airflow on the left side deflects to the left, and the airflow on the right side deflects to the right. In this way, the wall-mounted air conditioner indoor unit can form a fan-shaped wide-angle air supply effect, so that the air supply angle is larger and the airflow distribution is more uniform.

[0058] The aforementioned plurality of guide ribs may further include a third guide rib 543, which is located between the plurality of first guide ribs 541 and the plurality of second guide ribs 542, and whose extension direction is perpendicular to the length direction of the air guide plate body 51. That is, the function of the third guide rib 543 is to separate airflows deflected in different directions. Figure 2 As shown, the number of the plurality of first guide ribs 541 and the plurality of second guide ribs 542 can be the same, and they can be symmetrically distributed about the plane M where the third guide rib 543 is located. In this way, the air supply airflow can be split more evenly. In addition, the third guide rib 543 can be located on the symmetrical planes at both ends of the length direction of the air guide plate body 51 to make it more coordinated and beautiful, and the airflow distribution is more even.

[0059] like Figure 1 As shown, the first guide rib 541 and the second guide rib 542 can be bent along the cylindrical surface, so that when the supply air flow flows along the first guide rib 541 or the second guide rib 542, the deflection angle of the supply air flow gradually increases (the deflection angle refers to the angle at which the supply air flow deviates from the width direction of the air guide plate body), so that the direction change process of the supply air flow is smoother, which can reduce noise. In some alternative embodiments, the guide ribs can also extend in a plane that is at an acute angle to the width direction of the air guide plate. The present invention also provides a wall-mounted air conditioner indoor unit. Figure 4 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 11 and an air outlet 12. The air guide plate body 51 of the air guide plate 50 is rotatably mounted at the air outlet 12.

[0060] In some embodiments, Figures 1 to 4As shown, the 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 motor, which may be a stepping motor, for directly or indirectly driving the rotating arm 53 to rotate.

[0061] like Figure 4 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 (specifically, cold air during cooling and hot air during heating). 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 adjust the left and right air outlet direction of the air outlet 12.

[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.
