Detailed Description
Fig. 1 is a schematic view of an air deflection panel 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. 2, enlarged as compared to FIG. 1; fig. 4 is a schematic view of a wall-mounted air conditioner 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 4, the air deflector 50 of the embodiment of the present invention includes an air deflector body 51 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 plurality of air guiding ribs 541, 542, 543 protrude from the first side surface 511 of the air deflector body 51, and are configured to guide at least a portion of the air flow to gradually deflect toward an end of the air deflector body 51 in the length direction when the air flow passes through the first side surface 511. That is, the plurality of guide ribs 541, 542, and 543 guide portions of the blowing air flow to be gradually deflected to the left or to the right. Alternatively, a portion of the supply air flow may be deflected to the left and a portion of the supply air flow may be deflected to the right, as shown in FIG. 2. 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.
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, the plurality of flow guiding ribs 541, 542 and 543 may include a plurality of first flow guiding ribs 541 and a plurality of second flow guiding ribs 542 respectively located at different lengths 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. 2, 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 C 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. 2, 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.
In some embodiments, as shown in fig. 1-4, the air deflection plate 50 further includes 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 air conditioner is used for refrigerating, the air is blown upwards, so that the indoor quick and uniform refrigeration is realized, 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 the aviation baffle has the function of blowing up and wide angle formula air supply concurrently, and the design is very ingenious, and it is very little to improve moreover, and the cost is lower.
As shown in fig. 1 to 3, the wind-raising plate 52 may be shorter and 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 region of the middle section of the first side surface 511 in the length direction, which is close to the wind outlet end (a end) of the wind deflector body 51. Thus, the middle area of the air guide plate 50 in the length direction is enabled to be upward blown, and the areas on the two sides are not blown but wide-angle air guide is carried out, so that the air outlet flow of the whole air guide plate is more three-dimensional, dispersed and higher in comfort level.
As shown in fig. 3, the embodiment of the present invention provides the wind-raising plate 52 and the wind-guiding plate body 51 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-guiding plate 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. Moreover, the section of the airflow channel 521 formed between the wind-lifting plate 52 and the wind deflector body 51, which is close to the outlet, is tapered, so that the airflow can flow out at high speed, and the airflow can be prevented from accumulating in the airflow channel.
The wind-lifting plate 52 is connected with the wind deflector body 51 through a plurality of connecting ribs 55 to realize structural connection. The wind-lifting plate 52, the connecting rib 55 and the wind deflector body 51 can be made of an integral piece by an integral molding process, such as integral injection molding.
In some embodiments, the air deflector body 51 may include a main body section 501 which is a flat plate, and a bent section 502 bent and extended from an end of the main body section 501 close to the downstream of the air flow toward the direction facing the first side 511 (i.e., bent and extended toward the first side of the air deflector body 51). In the air guiding process of the air deflector, the bending section 502 can raise and blow out the air flow. For embodiments in which the scoop plate 52 is provided, the provision of the bend 502 can form the previously described airflow channel 521 in which the section adjacent the outlet is tapered.
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. 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. 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 for adjusting the left and right air outlet directions of the air outlet 12.
