Detailed Description
FIG. 1 is a schematic view of an air deflection plate according to an embodiment of the present invention; FIG. 2 is a schematic top view of the air deflection plate of FIG. 1; 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 second air-guiding rib of the air deflector; fig. 5 is a schematic view of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention. The flow direction of the air supply flow is indicated by solid arrows in the figure, 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.
As shown in fig. 1 to 5, the air deflector 50 according to the embodiment of the invention generally includes an air deflector body 51 and a plurality of air deflector rib groups 54. 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 5, 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 plurality of air guiding rib groups 54 are respectively disposed on different length sections of the air guiding plate body 51 (for example, in fig. 2, two air guiding rib groups 54 are respectively disposed on two length sections 501 and 502 of the air guiding plate body 51). Each of the air guiding rib groups 54 includes a first side surface 511 protruding upward when the air outlet 12 of the air deflector body 51 is opened, and a plurality of first air guiding ribs 541 and a plurality of second air guiding ribs 542 which are sequentially arranged at intervals along the length direction (x direction) of the air deflector body 51. The first air guiding rib 541 and the plurality of second air guiding ribs 542 extend in the downstream direction of the air flow and gradually incline towards the two ends of the length direction of the air guide plate body 51, so that the air flow flowing through the length section diffuses and flows out towards the two ends of the length section.
For example, in fig. 2, the first air guide rib 541 guides the supply air flow to be deflected to the left, and the second air guide rib 542 guides the supply air flow to be deflected to the right. 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 sets of the flow guiding ribs 54 are disposed on the air deflector body 51, so that a part of the air flow deviates from the width direction of the air deflector body 51, and the part of the air flow gradually diffuses towards the two side areas of the length direction of the air deflector body 51, i.e. diffuses leftwards and rightwards, 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.
Moreover, at the two ends of the air deflector body 51 in the length direction, the air flow is gradually diffused to the outer areas of the two ends of the air deflector body 51 in the length direction, and a fan-shaped air outlet surface is integrally formed, so that wide-angle air supply is realized, the temperature in a room is more uniform, and the human body feels more comfortable. Meanwhile, the intersection of the air supply airflow is generated at the junction of the two adjacent flow guide rib groups 54, the air supply airflow after intersection flows out of the air outlet forward with larger power, and the air supply distance is farther. Namely, the air deflector of the invention has the functions of wide-angle air supply and long-distance air outlet at the same time.
For example, in fig. 2, the number of the plurality of air guiding rib groups 54 is two, and the two air guiding rib groups are respectively located on two 1/2 length sections 501 and 502 (that is, the length of each length section is half of the length of the air guiding plate body, and the plane C is used as the dividing plane) of the air guiding plate body 51. Thus, the left air guide rib group 54 is deflected leftward in the left area S2 of the air guide plate body 51, and the right air guide rib group 54 is deflected rightward in the right area S3 of the air guide plate body 51. The middle of the two flow guide rib groups guides the air towards the left and right directions respectively to form an air flow intersection area S1, the air flow power at the position of S1 is stronger, and the air supply distance is longer.
Of course, in some alternative embodiments, three or more air guiding rib groups 54 may be provided to obtain more air flow converging areas, so that the air flow can be more remotely blown.
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.
Each first flow guiding rib 541 can be formed by smoothly connecting two sections, the two sections are respectively bent along different cylindrical surfaces, and the bending radius of the section adjacent to the air outlet end a of the air deflector body 51 is smaller. In addition, each second flow guiding rib 542 may be formed by two sections that are smoothly connected, the two sections are respectively bent along different cylindrical surfaces, and the bending radius of the section near the air outlet end a of the air deflector body 51 is smaller. For example, in fig. 4, the two sections of the second air guiding rib 542 have corresponding cylindrical surface radii of R1 and R2, respectively. R1 > R2. Therefore, when the air flow flows along the first diversion rib 541 or the second diversion 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), the direction conversion process of the air flow is more flexible, and the noise can be reduced. Further, the R1/R2 value can be in the range of 0.15 to 0.2, preferably 0.18, so that better flow guiding and noise reduction effects can be obtained.
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.
In some embodiments, as shown in fig. 1-5, the wind deflector 50 further comprises a wind-raising plate 52. The wind-raising plate 52 is mounted on the wind deflector body 51 and spaced apart from the first side surface 511. The air-lifting plate 52 is configured to cause the air-lifting plate 52 to direct the supply airflow to be deflected upward, i.e., to lift the wind, when the first side 511 is directed toward the outlet 12 to direct the supply airflow. For example, the wind-lifting plate 52 may be an arc-shaped plate with an axis parallel to the rotation axis of the wind deflector body 51 and a convex surface facing the first side surface 511.
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 air deflector of the embodiment of the invention has the functions of air blowing and wide-angle air supply, and has the advantages of ingenious design, small improvement and low cost.
As shown in fig. 3, the distance between the wind-up plate 52 and the wind deflector body 51 is gradually increased in the flow direction of the blowing air flow. In this way, the wind raising plate 52 can raise and guide the wind. Therefore, when the wall-mounted air conditioner indoor unit operates in a cooling mode, the air deflector body 51 does not need to be rotated to be in a state of being too close to the vertical state (namely, a state of closing the air outlet), so that the air deflector 50 is ensured to have a large enough opening degree, and the air volume is prevented from being influenced. Therefore, the wall-mounted air conditioner indoor unit has both air supply angle and air volume.
As shown in fig. 1 to 3, the wind-raising plate 52 may be narrower than the wind deflector body 51, and the projection of the wind-raising plate on the first side surface 511 is located in a half area of the first side surface 511 close to the wind outlet end (a end) of the wind deflector body 51. That is, the wind-lifting plate 52 is closer to the downstream of the airflow, so that the airflow receives the wind-lifting effect of the wind-lifting plate 52 just before flowing out of the wind-guiding plate, and the wind-lifting effect is better.
As shown in fig. 1 and 2, the wind-raising plate 52 may be shorter than the wind deflector body 51, so that the wind can be more smoothly discharged from the section of the wind deflector body 51 not covered by the wind-raising plate 52. In this way, the central region of the air guide plate 50 in the longitudinal direction is blown upward, and the end region is not blown upward but is blown wide, so that the air flow of the entire air guide plate is more three-dimensional, dispersed, and more comfortable.
As shown in fig. 3, in the embodiment of the present invention, the wind-raising plate 52 and the wind deflector body 51 are disposed at an interval to allow a small portion of the supplied air to flow out from the air flow channel 521 between the wind-raising plate 52 and the wind deflector body 51, so as to avoid the air flow from striking the windward end of the wind-raising plate 52 and generating an unfavorable backflow phenomenon.
The surface of the wind-raising plate 52 facing the wind deflector body 51 can be connected with the plurality of first wind-guiding ribs 541 and the plurality of second wind-guiding ribs 542, so as to realize the structural connection between the wind-raising plate 52 and the wind deflector body 51. The air-lifting plate 52, the first air-guiding rib 541, the plurality of second air-guiding ribs 542 and the air-guiding plate body 51 can be made into an integral piece by an integral forming process, such as integral injection molding, so as to facilitate processing and manufacturing and save cost.
The invention also provides a wall-mounted air conditioner indoor unit. As shown in fig. 5, the wall-mounted air conditioning indoor unit according to the embodiment of the present invention may generally include a casing 10 and the air guide plate 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 5, 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 drive means 70 comprise an electric motor for directly or indirectly driving the rotation arm 53 in rotation.
As shown in fig. 5, the outlet 12 may be located at a lower portion of the front side of the housing 10 and opened forward and downward. The rotating arm 53 is a bent arm with a bent portion and a downward opening. The driving device 70 is installed at the bottom wall of the wind tunnel 40. The purpose of setting up the bent arm is: at each angle of the air deflector 50 opening the air outlet 12, the first side surface 511 faces the air outlet 12, so that the air flow is guided by the first side surface 511, and the second side surface 512 faces away from the air outlet 12 and contacts with the ambient air, thereby facilitating the realization of the air mixing function of the air deflector 50. Moreover, the curved arm is also convenient to rotate the air deflector body 51 to the lower side of the casing 10, so as to completely avoid the air flow blown out from the air outlet 12, i.e. completely open the air outlet 12, and make the air deflector 50 completely not block the air flow.
On the basis, one or more inner guide plates 80 may be further disposed at the air outlet 12, and the inner guide plates 80 are rotatably mounted at the air outlet 12 and located inside the air guide plate 50 for adjusting the up-down air outlet direction of the air outlet 12. That is, the air guide plate 50 performs more functions of opening and closing the air outlet and mixing the air, and the inner guide plate 80 performs the functions of guiding the air and swinging the air upward and downward.
As shown in fig. 5, 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, which is disposed at an inlet of the air duct 40 to promote air to flow from the evaporator 20 to the air outlet 12, and 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.
