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 expand the diffusion angle of the wind guide plate in the left and right directions.

[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 the air supply airflow.

[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 rotatably mounted at the air outlet of the indoor unit of the wall-mounted air conditioner around a rotation axis parallel to its own length direction; and

[0010] A plurality of guide ribs protrude from a first side surface of the air guide plate body that faces upward when the air outlet is opened; and

[0011] The plurality of guide ribs are arranged at intervals along the length direction of the air guide plate body, and are configured to guide a portion of the air supply flow to gradually deflect toward the end of the air guide plate body in the length direction when the air supply flow flowing out of the air outlet passes through the first side surface.

[0012] Optionally, the multiple guide ribs include multiple first guide ribs and multiple second guide ribs respectively located in different length sections 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.

[0013] 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.

[0014] Optionally, the number of the plurality of first guiding ribs and the number of the plurality of second guiding ribs are the same, and are symmetrically distributed about the plane where the third guiding rib is located.

[0015] Optionally, the air guide plate further includes: an air lifting plate installed on the air guide plate body at a distance from the first side surface, and configured to guide the air supply air flow to deflect upward when the first side surface is directed toward the air outlet to guide the air supply air flow.

[0016] Optionally, the wind-raising plate is an arc-shaped plate whose axis is parallel to the rotation axis of the wind guide plate body and whose convex surface faces the first side surface.

[0017] Optionally, the wind-raising plate is shorter and narrower than the wind guide plate body, and its projection on the first side surface is located in the half area of ​​the first side surface in the middle section in the length direction close to the wind outlet end of the wind guide plate body.

[0018] Optionally, a section of the airflow channel formed between the wind-raising plate and the air-guiding plate body adjacent to the outlet is tapered, which is beneficial for accelerating the outflow of the airflow.

[0019] Optionally, the air guide plate body includes a main body section which is a flat plate and a bent section which is bent and extended from an end of the main body section close to the downstream of the airflow toward a direction facing the first side surface.

[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 an air guide plate according to any of the above items, wherein the air guide plate body is rotatably installed at the air outlet.

[0021] In the air guide plate of the present invention, a plurality of guide ribs are arranged on the first side surface of the air guide plate body. 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 plurality of guide ribs guide part of the air supply airflow to gradually deflect toward the end of the length direction of the air guide plate body, that is, deviate from the width direction of the air guide plate body, so that the part of the air supply airflow gradually diffuses to the areas on both 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 realized, so that the temperature inside the room is more uniform and the human body feels more comfortable.

[0022] Furthermore, the air guide plate of the present invention has multiple guide ribs including a first guide rib, a second guide rib and a third guide rib, so that the middle supply air flow flows from both sides of the third guide rib along the width direction of the air guide plate body, and the two side supply air flows are respectively deflected to the sides under the guidance of the first guide rib and the second guide rib, thereby forming a fan-shaped wide-angle air supply effect, and the airflow distribution is more uniform.

[0023] Furthermore, the wind guide plate of the present invention is also provided with a wind lifting plate. When the first side surface of the wind guide plate body is directed toward the air outlet to guide the air supply airflow, the wind lifting plate guides the air supply airflow to deflect upward, that is, the wind is lifted and blown out. In addition, since a special wind lifting plate is provided, the wind lifting angle can be designed to be larger, which fully meets the requirements for the upward lifting angle in the air conditioning cooling or non-blowing mode. The wind guide plate of the present invention has the functions of both wind lifting and air supply and wide-angle air supply, and the design is very clever.

[0024] Furthermore, in the wind guide plate of the present invention, the wind lifting plate and the wind guide plate body are spaced apart to allow a small portion of the air supply airflow to flow out from the airflow channel between the wind lifting plate and the wind guide plate body, thereby preventing part of the airflow from hitting the windward end of the wind lifting plate and causing an unfavorable backflow phenomenon. In addition, the section of the airflow channel near the outlet is tapered to facilitate the airflow to flow out faster and avoid stagnation of the airflow therein.

[0025] 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

[0026] 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:

[0031] 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 top view of the wind deflector shown; Figure 3 yes Figure 2 NN section view of the wind deflector shown, compared Figure 1 Amplification was performed; Figure 4Schematic diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention. The solid arrows in the figure indicate the flow direction of the air supply airflow, 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.

[0032] like Figures 1 to 4 As shown, the air deflector 50 of the embodiment of the present invention includes an air deflector body 51 and a plurality of guide ribs 541, 542, 543. 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-axis 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.

[0033] For example Figures 1 to 4 As shown, the air guide plate body 51 can be installed horizontally or nearly horizontally on the air outlet 12 with its rotation axis so that its length direction is parallel to the left-right direction, so as to adjust the up-and-down air outlet angle of the air outlet 12.

[0034] 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.

[0035] The plurality of guide ribs 541, 542, 543 protrude from the first side surface 511 of the air guide body 51, and are configured to guide at least a portion of the air supply air flow to gradually deflect toward the end of the length direction of the air guide body 51 when the air supply air flow flows through the first side surface 511. That is, the plurality of guide ribs 541, 542, 543 guide a portion of the air supply air flow to gradually deflect to the left or to the right. Alternatively, a portion of the air supply air flow is deflected to the left, and a portion of the air supply air flow is deflected to the right, such as Figure 2 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] In some embodiments, the aforementioned plurality of guide ribs 541, 542, 543 may include a plurality of first guide ribs 541 and a plurality of second guide ribs 542 respectively located at different length sections of the air guide 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 both ends of the length direction of the air guide body 51. Please refer to Figure 2 , 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.

[0041] 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 2As 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 C 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.

[0042] like Figure 2 As shown, the first guide rib 541 and the second guide rib 542 can be bent along the cylindrical surface, so that when the air supply airflow flows along the first guide rib 541 or the second guide rib 542, the deflection angle of the air supply airflow gradually increases (the deflection angle refers to the angle at which the air supply airflow deviates from the width direction of the air guide plate body), so that the direction change process of the air supply airflow is smoother, which can reduce noise. In some alternative embodiments, the guide rib can also extend in a plane that is at an acute angle to the width direction of the air guide plate.

[0043] In some embodiments, Figures 1 to 4 As shown, the wind guide plate 50 further includes a wind raising plate 52. The wind raising plate 52 is mounted on the wind guide plate body 51 and is spaced apart from the first side surface 511. The wind raising plate 52 is configured to guide the air supply airflow to deflect upward when the first side surface 511 is directed toward the air outlet 12 to guide the air supply airflow, that is, to make the air rise and blow out. For example, the wind raising plate 52 may be an arc-shaped plate with an axis parallel to the rotation axis of the wind guide plate body 51 and a convex surface facing the first side surface 511.

[0044] When the air conditioner is cooling, blowing the wind upward is conducive to achieving faster and more uniform cooling in the room, and the air supply distance is farther. In addition, blowing the cold or hot air upward can also avoid the wind from blowing directly on the human body to avoid discomfort. 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 wind guide plate of the embodiment of the present invention has the functions of both wind-raising and wide-angle air supply, and the design is very clever, and the improvement is very small, and the cost is low.

[0045] like Figures 1 to 3 As shown, the wind-raising plate 52 can be made shorter and narrower than the wind guide body 51, and its projection on the first side surface 511 is located in the half area of ​​the first side surface 511 in the middle section in the length direction close to the wind outlet end (end A) of the wind guide body 51. In this way, the middle area in the length direction of the wind guide 50 is used to raise the wind upward, and the two side areas are not used to raise the wind but to guide the wind at a wide angle, which makes the airflow of the entire wind guide plate more three-dimensional, dispersed, and more comfortable.

[0046] like Figure 3As shown, in the embodiment of the present invention, the wind-raising plate 52 and the wind-guiding plate body 51 are spaced apart to allow a small portion of the air supply airflow to flow out from the airflow channel 521 between the wind-raising plate 52 and the wind-guiding plate body 51, thereby preventing the airflow from hitting the windward end of the wind-raising plate 52 and causing an unfavorable backflow phenomenon. In addition, the section of the airflow channel 521 formed between the wind-raising plate 52 and the wind-guiding plate body 51 near the outlet is tapered, which is conducive to accelerating the outflow of the airflow and preventing the airflow from accumulating therein.

[0047] The wind raising plate 52 is connected to the wind deflector body 51 through a plurality of connecting ribs 55 to achieve structural connection. The wind raising plate 52, the connecting ribs 55 and the wind deflector body 51 can be an integral part made by an integral molding process, such as integral injection molding.

[0048] In some embodiments, the air guide body 51 may include a main body section 501 that is a flat plate and a bent section 502 that bends and extends from the end of the main body section 501 that is close to the downstream of the air flow toward the direction facing the first side surface 511 (i.e., bends and extends toward the first side of the air guide body 51). During the air guide process, the bent section 502 can lift the air flow and blow it out. For embodiments in which the air lifting plate 52 is provided, the bent section 502 can form the aforementioned air flow channel 521 with a tapered section near the outlet.

[0049] 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.

[0050] In some embodiments, Figures 1 to 4 As 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 around the first end of the rotating arm 53. 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 for directly or indirectly driving the rotating arm 53 to rotate.

[0051] like Figure 4As 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.

[0052] 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.
