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.

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 of the embodiment of the present 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. And in the embodiment of the utility model, owing to set up special board of raising the wind, the designer can be bigger with the angle design of raising the wind to fully provided the requirement of air conditioner to the angle of raising the wind. The utility model discloses only through add a portion 52 that rises wind on aviation baffle 50 and just realized the function of rising wind, the design is very ingenious, and the structure is very simple, and the cost is lower. 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.
The embodiment of the present invention provides a plurality of guiding ribs 541, 542, 543 are disposed on the air deflector body 51, so that at least a portion of the air flow is deviated from the width direction of the air deflector body 51, and the portion of the air flow is gradually diffused to both sides of the length direction of the air deflector body 51, i.e., 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, the air supply airflow will be directly blown out from the air outlet 12 after generating deflection, and 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 utility model discloses an aviation baffle has realized raising of air supply air current and has blown off and increase the diffusion angle of air supply air current at the left and right sides orientation, has still realized that the drainage mixes the wind, and the function is very powerful, and the design is very ingenious.
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 utility model also provides a wall-hanging air conditioning indoor set. As shown in fig. 4, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and the air guide plate 50 according to any 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 shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
