In one aspect, the present invention provides an air deflector for a wall-mounted air conditioner indoor unit, comprising:
the air deflector body is used for being rotatably arranged at an air outlet of the wall-mounted air conditioner indoor unit around an axis parallel to the length direction of the air deflector body;
the two wind raising parts are arranged at intervals along the length direction of the air deflector body, each wind raising part protrudes out of the first side surface of the air deflector body which faces upwards when the air outlet is opened, and the wind raising parts are configured to guide the air supply airflow to gradually leave the air deflector body to flow obliquely upwards when the air supply airflow flows through the first side surface; and

Optionally, two through-penetrating drainage openings are formed in the air deflector body, and each drainage opening is located on the downstream side of the air flow at the joint of one air raising portion and the air deflector body, so that when the air supply air flow is gradually far away from the air deflector body to flow, the ambient air on the other side of the air deflector body is driven to converge into the air supply air flow through the drainage openings.
Optionally, the scoop includes a scoop plate that is progressively further away from the first side in the airflow direction from the airflow upstream edge of the drainage opening.
Optionally, the end of the scoop plate in the direction of airflow exceeds the drainage opening to define with the first side a drainage channel in communication with the drainage opening.
Optionally, the projection of the wind-lifting plate on the first side surface is located within the range of the wind deflector body.
Optionally, the wind pumping part further comprises a plurality of connecting ribs arranged at intervals along the parallel direction of the rotation axis of the wind deflector body, and each connecting rib connects the wind pumping plate and the wind deflector body.
Optionally, the wind-lifting plate is an arc-shaped plate with a central axis parallel to the rotation axis of the wind deflector body and a convex surface facing the wind deflector body.
Optionally, the plurality of flow guide ribs comprise a plurality of first flow guide ribs and a plurality of second flow guide ribs which are sequentially arranged at intervals along the length direction of the air deflector body; the first flow guide rib and the second flow guide rib extend towards the downstream direction of the air supply airflow and incline towards the two ends of the length direction of the air guide plate body gradually respectively.
Optionally, the plurality of flow guide ribs further include a third flow guide rib, which is located between the plurality of first flow guide ribs and the plurality of second flow guide ribs, and the extending direction is perpendicular to the length direction of the air deflector body.
In another aspect, the present invention further provides a wall-mounted air conditioner indoor unit, including: a shell which is provided with an air outlet; and the air deflector is the air deflector according to any one of the above items, wherein the air deflector body is rotatably mounted at the air outlet.
Optionally, the air deflector further comprises at least one rotating arm, one end of the rotating arm is connected with the driving device positioned in the shell, and the other end of the rotating arm is connected with the air deflector body, so that the air deflector body is driven by the driving device to rotate around the first end of the rotating arm upwards to close the air outlet or rotate downwards to open the air outlet; and an inner guide plate is also arranged at the air outlet and is positioned at the inner side of the air deflector.
The air deflector can better raise and blow out the air supply flow, increases the diffusion angle of the air supply flow in the left and right directions, and has a very ingenious design. Specifically, when the air supply airflow flows through the upward first side face of the air deflector body, the air blowing part changes the flowing direction of the air supply airflow, so that the air supply airflow gradually gets away from the air deflector body and flows obliquely upward, namely is blown upward. Due to the fact that the special wind raising portion is arranged, the wind raising angle can be designed to be larger, the wind direction is closer to vertical and upward, and the requirement for the wind raising angle in the air conditioner refrigeration or non-blowing mode is fully met.
And when the air deflector is in the air guiding state and the air supply airflow flowing out of the air outlet flows through the first side surface, the air supply airflow is guided by the plurality of flow guide ribs to gradually incline towards two ends of the length direction of the air deflector body, namely to gradually diffuse towards two side areas of the length direction of the air deflector body. Therefore, the diffusion angle of the air outlet in the left and right directions is increased, wide-angle air supply is realized, the temperature in a room is more uniform, and the human body feels more comfortable.
And because a plurality of water conservancy diversion muscle set up between two wind-lifting portion. The left and right sections of the air deflector raise the wind upwards to guide the wind higher and farther. The intermediate section is wide-angle, blowing, directing the wind at a relatively low, but much wider angle. The air supply airflows of different length sections of the air deflector are staggered in the up-down left-right direction respectively, so that the multi-dimensional air outlet effect is realized, the airflows are more dispersed, and the comfort is higher.
Furthermore, the air deflector disclosed by the invention also has an air mixing function. When the air supply airflow flows through the first side surface of the air deflector body, the air raising part changes the flowing direction of the air supply airflow and enables the air raising part to be far away from the first side surface of the air deflector body, so that the airflow density at the first side surface of the air deflector body is reduced, and negative pressure is formed. Under the suction of the negative pressure area, ambient air on the second side of the air deflector body enters the negative pressure area through a drainage port formed in the air deflector body and then is converged into air supply airflow to form an air mixing effect. When the air conditioner is used for refrigeration, the temperature of the air supply airflow can be properly increased by mixing the ambient air; when the air conditioner heats, the mixing of the ambient air can properly reduce the temperature of the air supply flow, so that the air supply flow is more comfortable.
Furthermore, the wind mixing function is realized only by arranging the drainage port on the wind deflector body and additionally arranging the wind raising part, and the wind mixing device is ingenious in design, simple in structure and low in cost. In addition, other structures of the wall-mounted air conditioner indoor unit do not need to be changed, and the wall-mounted air conditioner indoor unit is very beneficial to mass production and popularization.
Furthermore, the tail end of the air raising plate along the airflow direction exceeds the drainage port so as to define a drainage channel communicated with the drainage port with the first side surface, the air raising plate can guide the flow direction of ambient air, the included angle between the air raising plate and the air supply airflow is smaller, the ambient air and the air supply airflow are mixed more softly, and the problems that the ambient air directly passes through the drainage port and vertically enters the air supply airflow to cause overlarge noise and the like are avoided.
The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

Detailed Description
FIG. 1 is a schematic view of an embodiment of an air deflection plate according to the present invention; FIG. 2 is a schematic view of the wind deflector of FIG. 1 from another perspective; FIG. 3 is an N-N cross-sectional view of the deflector of FIG. 1, enlarged as compared to FIG. 1; fig. 4 is a schematic view of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention. The x-axis is the central axis of the air deflector body, and the y-axis is parallel to the width direction of the air deflector body. The solid arrows indicate the direction of the supply air flow and the hollow arrows indicate the direction of the intake of ambient air.
As shown in fig. 1 to 4, the air deflector 50 according to the embodiment of the invention generally includes an air deflector body 51, two wind-raising portions 52, and a plurality of air guiding ribs 541, 542, and 543.
The air deflector body 51 is rotatably installed at the outlet 12 of the casing 10 of the wall-mounted air conditioning indoor unit. The air guide plate body 51 is elongated as a whole, and has a longitudinal direction and a width direction. The x-axis of the rotation 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 for opening or closing the air outlet 12 and adjusting the air outlet angle of the air outlet 12.
For example, as shown in fig. 1 to 4, the air deflector body 51 may be installed at the air outlet 12 with a rotation axis horizontal or nearly horizontal, and the length direction thereof is parallel to the left-right direction, so as to adjust the up-down air outlet angle of the air outlet 12.
The airflow blown out from the inside of the casing 10 through the outlet 12 is the supply airflow. When the air conditioner is used for refrigerating, the air supply flow is cold air; when the air conditioner heats, the air supply flow is hot air. When the air outlet 12 is opened, the upward side of the air deflector body 51 is the first side, and the surface thereof is the first side surface 511; the downward side is the second side, and its surface is the second side 512. When the outlet 12 is opened, the air deflector body 51 is defined as a windward end (B end) at an end close to the upstream of the supply airflow and an air-out end (a end) at an end close to the downstream of the supply airflow. The flow direction of the blowing air flow on the first side surface 511 of the air deflector body 51 is towards the air outlet end.
The two wind-raising portions 52 are arranged at intervals along the longitudinal direction of the air deflector body 51. The air blowing part 52 is convexly arranged on the upward first side surface 511 of the air deflector body 51 when the air outlet 12 is opened, and is configured to guide the air supply flow to gradually leave away from the air deflector body 51 to gradually obliquely flow upwards when the air supply flow flows through the first side surface 511, and the wind direction can be closer to vertically upwards, so that the wall-mounted air conditioner indoor unit can realize better upward blowing, and the wind can better avoid the human body.
When the wall-mounted air conditioner indoor unit is used for refrigerating, wind is blown upwards to facilitate the indoor quick and uniform refrigeration, and the air supply distance is longer. In addition, the cold air or the hot air can be blown out upwards to avoid the human body, so that the discomfort caused by directly blowing the human body can be avoided. In the embodiment of the invention, because the special wind raising plate is arranged, a designer can design the wind raising angle to be larger so as to fully meet the requirement of the air conditioner on the wind raising angle. The invention realizes the wind raising function only by adding the wind raising part 52 on the wind deflector 50, and has the advantages of ingenious design, simple structure and lower cost. In addition, other structures of the wall-mounted air conditioner indoor unit do not need to be changed, and the wall-mounted air conditioner indoor unit is very beneficial to mass production and popularization.
The plurality of air guiding ribs 541, 542, 543 protrude from the first side surface 511, are arranged between the two air blowing portions 52 at intervals along the length direction of the air deflector body 51, and are configured to guide the blowing air flow to gradually deflect towards two ends of the length direction of the air deflector body 51 when the blowing air flow passes through the first side surface 511. That is, the plurality of air guide ribs 541, 542, and 543 guide a portion of the air flow to deflect left and a portion of the air flow to deflect right, as shown in fig. 1. The plurality of ribs and the air deflector body 51 may be formed as an integral part by an integral molding process, such as integral injection molding.
When the air deflector of the prior art is used for guiding air, the air flow flows only along the width direction of the air deflector, so that the air flow is blown out from the air outlet in a nearly parallel manner to form a rectangular air flow. The inside of the air outlet is usually provided with a swing blade to adjust the left and right air outlet directions of the air outlet.
In the embodiment of the present invention, the plurality of flow guiding ribs 541, 542, and 543 are disposed on the air deflector body 51, so that at least a portion of the air flow deviates from the width direction of the air deflector body 51, and the portion of the air flow gradually diffuses toward the two side areas of the length direction of the air deflector body 51, i.e., diffuses leftward or rightward, thereby forming a fan-shaped air flow. Therefore, the wall-mounted air conditioner indoor unit using the air guide plate increases the diffusion angle of the air outlet in the left and right directions, realizes a wide-angle air supply effect, and enables the temperature in a room to be more uniform and the human body to feel more comfortable.
And because a plurality of water conservancy diversion muscle set up between two wind-lifting portion. The left and right sections of the air deflector raise the wind upwards to guide the wind higher and farther. The intermediate section is wide-angle, blowing, directing the wind at a relatively low, but much wider angle. Based on this, the air supply air current of the different length sections of aviation baffle staggers respectively in upper and lower left and right direction, has realized the three-dimensional air-out effect of multidimension, and its air current is more dispersed, and the travelling comfort is higher.
In some alternative ways, two sets of separately controlled swing vanes may be provided. When the left side swing blades swing towards the left and the right side swing blades swing towards the right, the air outlet also has a wide-angle air supply effect. However, since the flap is located further inside the outlet than the air guide plate, the supply airflow is not directly blown out of the outlet after being guided by the deflection of the flap, but is also directed up and down by the air guide plate by hitting the surface of the air guide plate. However, the deflection degree of the deflected airflow is not so small as to generate attenuation when the deflected airflow hits the surface of the air deflector and is guided upwards or downwards by the air deflector, and it is difficult to obtain the desired wide-angle air supply effect.
In the embodiment of the present invention, the deflection acting force is directly applied to the air supply airflow by the guiding ribs on the air deflector body 51, and the air supply airflow is directly blown out from the air outlet 12 after being deflected, so that the deflection degree is not affected by other components.
In some embodiments, as shown in fig. 1 to 4, two through drainage ports 515 are formed in the air deflector body 51, and the drainage ports 515 penetrate two side surfaces of the air deflector body 51. Each of the drainage openings 515 is located on an airflow downstream side of a connection of one of the wind-lifting portions 52 and the air deflector body 51. When the air current flows away from the air deflector body 51 gradually due to the air blowing action of the air blowing portion 52, a negative pressure is formed at the first side surface 511, so as to drive the ambient air at the second side (i.e. the lower side) of the air deflector body 51 to be merged into the air current through the drainage opening 515.
That is, since the wind-blowing portion 52 causes the blowing air flow to be away from the first side surface 511, the air flow density at the first side surface 511 of the air deflector body 51 is reduced, and a negative pressure region is formed (the S region in fig. 4 roughly indicates a negative pressure region range). Under the suction of the negative pressure region, the ambient air on the second side of the air deflector body 51 enters the negative pressure region through the drainage port 515 formed on the air deflector body 51, and then is converged into the air supply flow, so as to form an air mixing effect. When the air conditioner is used for refrigeration, ambient air is mixed into the air supply airflow, so that the temperature of the air supply airflow can be properly increased; when the air conditioner heats, the temperature of the air supply airflow can be properly reduced by mixing the ambient air, so that the air supply airflow is more comfortable, and the comfortable air supply of the air conditioner is realized.
The air deflector realizes the upward blowing of the air supply flow, increases the diffusion angle of the air supply flow in the left and right directions, also realizes the drainage and air mixing, and has very powerful function and very ingenious design.
In some embodiments, each of the wind scoops 52 may include a wind scoop 521 gradually distant from the first side 511 in the airflow direction from the airflow upstream edge (C-side) of the drainage opening 515. Or, the wind-lifting plate 521 extends from the first side surface 511, and the extending direction is toward the downstream side of the blowing air flow, and the wind-lifting plate gradually gets away from the first side surface in the extending process. Under the guidance of the wind-up plate 521, the supply airflow gradually moves away from the first side 511 of the wind deflector 50, and a negative pressure region is generated at the first side 511. The embodiment makes the starting end of the wind-lifting plate 521 directly connected with the edge of the drainage port 515, so that the connection transition section of the wind-lifting plate and the drainage port is smoother, and the air flow is better guided.
As shown in fig. 3, the projection of the air-lifting plate 521 on the first side 511 at least covers the air-guiding opening 515, and the air-lifting plate 521 can avoid the problem that the ambient air directly enters the air-supply airflow vertically through the air-guiding opening 515, which causes excessive noise, etc. Further, the end (E-end) of the wind-lifting plate 521 in the airflow direction may be positioned beyond the drainage port 515 (referring to the edge D of the downstream airflow edge of the drainage port 515) to define a drainage channel 516 communicating with the drainage port 515 with the first side 511. The flow direction of the ambient air is guided by the flow guide 516 so that when the ambient air merges with the supply air, the two air streams have a smaller included angle and are mixed more gently.
The projection of the wind-lifting plate 521 on the first side 511 can be located within the range of the wind deflector body 51. In other words, the end (E end) of the wind-raising plate 521 is retracted a distance in the upstream direction of the blowing air flow compared with the wind-out end (a end) of the wind deflector body 51. It can also be understood that, by making a perpendicular line to the first side 511 of the deflector body 51 at the end of the deflector 521, the foot will fall on the first side 511 itself rather than on the extension of the first side 511. This allows the section of the air deflector body 51 protruding from the air deflector 521 to guide and block the ambient air flowing out of the flow guiding channel 516 to a certain extent, so that it can be better mixed with the supply air flow. The air deflector body 51 can also avoid the contact between the air deflector 521 and the upper edge of the air outlet 12 when the air outlet 12 is closed.
As shown in fig. 1 and 2, the wind-lifting portion 52 may further include a plurality of connection ribs 522 arranged at intervals along the parallel direction of the rotation axis of the wind deflector body 51, and each connection rib 522 connects the wind-lifting plate 521 and the wind deflector body 51 to realize the structural connection. In addition, the connecting ribs 522 can also split the ambient air, so that the air flow is softer. It will be appreciated that the ribs 522 are located on the downstream side of the supply air flow relative to the vents 515. In other words, the ribs 522 divide the drainage channel 516 into a plurality of small channels. The wind-raising portion 52 and the wind deflector body 51 can be an integral piece, so as to be convenient for processing and manufacturing.
Two of the plurality of connection ribs 522 may be connected between both ends of the wind scooper 521 in the rotational axis direction of the wind scooper body 51 and the first side surface 511 to close the interval between the both ends of the wind scooper 521 and the first side surface 511. This prevents the air flow from flowing in the direction of the rotational axis of the air deflection plate body 51, thereby preventing the occurrence of adverse eddy currents and noise.
As shown in fig. 1 to 4, the wind-lifting plate 521 can be a curved plate with a central axis parallel to the rotation axis of the wind deflector body 51 and a convex surface facing the wind deflector body 51, so as to better lift and guide the wind flow. The length direction of the drainage opening 515 is parallel to the length direction of the air deflector body 51, so that the air mixing amount is larger.
In some alternative embodiments, the scoop 521 may not completely cover the vent 515. Even more, the projection of the scoop 521 at the first side 511 can be made to fall on the upstream area of the vent, not on the vent 515 at all. Alternatively, the wind-blowing portion 52 is a convex strip protruding from the first side surface 511, and the cross section of the convex strip is arc-shaped or triangular. The specific structure will not be described in detail.
For example, as shown in fig. 1, the plurality of air guiding ribs may include a plurality of first air guiding ribs 541 and a plurality of second air guiding ribs 542 which are sequentially arranged at intervals in the length direction of the air deflector body 51. The first and second flow guiding ribs 541 and 542 extend in a downstream direction of the air flow (i.e., a direction from the air inlet end to the air outlet end, i.e., a y-axis direction) and gradually incline toward two ends of the length direction of the air guide plate body 51. Referring to fig. 1, the first flow guiding ribs 541 extend along the downstream direction of the blowing air flow and deflect towards the left, and the second flow guiding ribs 542 extend along the downstream direction of the blowing air flow and deflect towards the right, so that the left portion of the air flow deflects towards the left and the right portion of the air flow deflects towards the right. Therefore, the wall-mounted air conditioner indoor unit can form a fan-shaped wide-angle air supply effect, the air supply angle is larger, and the air flow distribution is more uniform.
The plurality of flow guiding ribs may further include a third flow guiding rib 543, wherein the third flow guiding rib 543 is located between the plurality of first flow guiding ribs 541 and the plurality of second flow guiding ribs 542, and the extending direction is perpendicular to the length direction of the air deflector body 51. That is, the third flow guiding rib 543 functions to divide the air flow deflected in different directions. As shown in fig. 2, the number of the first guiding ribs 541 and the number of the second guiding ribs 542 may be the same, and the first guiding ribs 541 and the second guiding ribs 542 are symmetrically distributed about the plane M where the third guiding ribs 543 are located. This makes it possible to make the split of the supply air flow more uniform. In addition, the third guiding ribs 543 can be located on the symmetrical planes at the two ends of the air deflector body 51 in the length direction, so that the air deflector body is more harmonious and attractive, and the air flow distribution is more uniform.
As shown in fig. 1, the first flow guiding rib 541 and the second flow guiding rib 542 may be curved along the cylindrical surface, so that when the air flow flows along the first flow guiding rib 541 or the second flow guiding rib 542, the deflection angle of the air flow is gradually increased (the deflection angle refers to the angle of the air flow deviating from the width direction of the air deflector body), so that the direction of the air flow is changed more smoothly, and thus, the noise is reduced. In alternative embodiments, the ribs may also extend in a plane that is at an acute angle to the width of the air deflection panel. The invention also provides a wall-mounted air conditioner indoor unit. As shown in fig. 4, the wall-mounted air conditioning indoor unit according to the embodiment of the present invention may generally include a casing 10 and the air deflector 50 according to any one of the embodiments. The housing 10 is provided with an air inlet 11 and an air outlet 12. The air deflector body 51 of the air deflector 50 is rotatably installed at the air outlet 12.
In some embodiments, as shown in fig. 1 to 4, the air deflector 50 further includes at least one rotating arm 53 having one end connected to the driving device 70 located inside the casing 10 and the other end connected to the air deflector body 51. Under the driving of 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 upwards to close the air outlet 12, or rotate downwards to open the air outlet 12. A plurality of the rotation arms 53 may be provided such that the plurality of rotation arms 53 are arranged at intervals along the length direction of the air deflection body 51. The driving means 70 comprises a motor, which may be a stepping motor, for directly or indirectly driving the turning arm 53 to turn.
As shown in fig. 4, the wall-mounted air conditioning indoor unit may include an evaporator 20, a blower 30, a duct 40, and a swing vane 60. The evaporator 20 is used for exchanging heat with 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 communicates with the air outlet 12. The fan 30 may be a cross-flow fan disposed at an 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 directions of the air outlet 12.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
