In each figure, the direction of the flow of the supply air is indicated by solid arrows, and the direction of the intake of the ambient air is indicated by hollow arrows.
As shown in fig. 1 to 5, the wind deflector 50 of the present invention generally includes a wind deflector body 51 and one or more wind-raising plates 52. The air deflector body 51 is installed at the outlet 12 of the casing 10 of the wall-mounted air conditioning indoor unit. The air deflector 50 is used for opening and closing the air outlet 12, and can also be used for adjusting the 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. The air deflector body 51 has an elongated plate shape and has two side surfaces, a first side surface 511 and a second side surface 512. The two ends of the air deflector body 51 in the width direction are respectively a first end (a end) and a second end (B end). The air deflector body 51 is provided with a drainage port 515 which penetrates through the first side surface 511 and the second side surface 512.
The wind-raising plate 52 extends from the first side surface 511 toward the first end (end a) of the wind deflector body 51 and gradually away from the first side surface 511, and the starting end is closer to the second end (end B) of the wind deflector body 51 relative to the drainage opening 515. When the air deflector 50 is located at a position where the first side 511 faces upward and the first end (end a) faces forward (when the wall-mounted air conditioner indoor unit is normally installed, the side of the air deflector close to the wall is the rear side, and the side far from the wall is the front side, thereby defining the front-rear direction), the direction of the air flow blown out from the air outlet 12 is changed when the air flow passes through the air raising plate 52, so that a negative pressure is formed at the first side 511, so as to drive the ambient air at the other side (i.e., the side facing the second side 512) of the air deflector body 51 to be merged into the air flow through the drainage port 515, as shown in fig. 5.
That is, the blowing air flow is gradually separated from the first side 511 by the guide of the wind-up plate 52, so that the air flow density at the first side 511 of the wind deflector body 51 is reduced to form a negative pressure region (the region S1 in fig. 5 roughly indicates the 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.
As shown in fig. 1 to 5, the air-lifting plate 52 is provided with an air-passing opening 525 to allow a part of the ambient air to be sequentially merged into the supply air flow through the air-guiding opening 515 and the air-passing opening 525. That is, the surface of the wind-lifting plate 52 has a relatively high flow velocity, and the air pressure is lower than the internal air pressure of the flow-through opening 525, so that a negative pressure region S2 is formed, and after the ambient air enters the flow-guiding opening 515, a part of the ambient air is also merged into the blowing air flow through the flow-through opening 525, which further increases the mixed air volume.
For example, the ratio of the width of the flow opening 525 to the width of the wind-lifting plate 52 (referring to the distance from the extension start end to the extension end) can be set to be between 1/3 and 1/2, so as to avoid the influence of the excessive flow opening on the wind-lifting effect. The overflow vent 525 may be positioned near the beginning half of the scoop 52 so as to be directly opposite the location of the vent 515 to facilitate ambient air entering the overflow vent 525 from the vent 515.
The utility model discloses only through at aviation baffle 50 upper shed and add a board 52 that rises and just realized mixing the wind function, 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.
When the air deflector 50 is in the upward blowing position (see fig. 5), the wall-mounted air conditioner indoor unit can achieve both the air outlet angle and the air volume. For example, in order to improve the air blowing comfort, when the wall-mounted air conditioning indoor unit cools, it is generally desirable that the air guide plate guides the cool air to blow out as vertically upward as possible. However, when the air deflector of the conventional wall-mounted air conditioner indoor unit rotates to an upward blowing angle close to the limit, the included angle between the air deflector and the plane of the air outlet is too small, that is, the opening degree is very small (the opening degree of the air deflector refers to the degree of opening the air outlet, and when the air deflector completely closes the air outlet, the opening degree is zero, when the air deflector completely opens the air outlet (refer to fig. 5), the opening degree is 100%, the air outlet is most smooth), the air deflector can seriously shield the air outlet, and the air volume becomes very small. This limits the wind guiding angle range of the wind guiding plate. Especially, when the air is guided vertically, the air guiding angle and the air volume are difficult to be considered simultaneously.
In the embodiment of the present invention, the wind raising plate 52 can raise wind for guiding. 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. 4, the end (E-end) of the wind-raising plate 52 may be positioned beyond the drainage port 515 (referring to the end D of the drainage port 515 near the first end of the wind deflector body 51) 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 52 on the first side 511 can be located in the range of the wind deflector body 51. In other words, the end (E end) of the wind-raising plate 52 is retracted to the second end (B end) of the wind deflector body by a distance compared with the first end (a end) of the wind deflector body 51. It can also be understood that, when the end (E end) of the wind-raising plate 52 is perpendicular to the first side 511 of the wind-guiding plate body 51, 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 52 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. In addition, when the air deflector body 51 closes the outlet 12, the air deflector 52 is prevented from contacting the upper edge of the outlet 12.
In some alternative embodiments, the scoop 52 may not completely cover the vent 515.
As shown in fig. 1 to 3, the air deflector 50 further includes a plurality of connecting ribs 522 arranged at intervals along a length direction (parallel to the x-axis direction of fig. 1) of the air deflector body 51, and each connecting rib 522 connects the air deflector 52 and the air deflector body 51 to realize structural connection. In addition, the ribs 522 divide the flow channel 516 into multiple sub-channels, splitting the ambient air and making the airflow softer. The wind-lifting plate 52, the connecting rib 522 and the wind deflector body 51 can be an integral piece formed integrally, 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-up plate 52 in the length direction of the wind deflector body 51 and the first side surface 511 to close the interval between the both ends of the wind-up plate 52 and the first side surface 511, so that the flow of the air along the length direction of the wind deflector body 51 may be prevented, thereby preventing the occurrence of an unfavorable vortex and noise.
As shown in fig. 1 to 4, the air deflector body 51 may be installed to the outlet 12 to extend horizontally in the longitudinal direction. The air deflector body 51 can be an arc-shaped plate with a concave first side surface 511 and a central axis parallel to the length direction of the air deflector body 51, and the air raising plate 52 is an arc-shaped plate with a central axis parallel to the central axis of the air deflector body 51 and a convex surface facing the air deflector body 51, so as to better raise and guide the air flow.
An included angle between a tangent line (a tangent line of the arc surface) at the first end (a end) of the air deflector body 51 and a tangent line (a tangent line of the arc surface) at the tail end (E end) of the air deflector 52 is θ. The inventor finds that too small an angle will make the wind-blowing effect insufficient, and too large an angle will make the wind-direction turning angle too large and make the wind resistance too large when the wind-blowing airflow flows from the surface of the first side 511 to the surface of the wind-blowing plate 52. The most preferred range of this angle is between 25 ° and 35 °. θ is preferably 30 °.
Fig. 7 is a schematic structural view of an air deflector according to another embodiment of the present invention; FIG. 8 is an enlarged view of the deflector of FIG. 7 at N; FIG. 9 is a schematic view of the deflector of FIG. 7 from another perspective; fig. 10 is a cross-sectional view of the air deflection plate shown in fig. 7.
The air deflection panel of the embodiment shown in fig. 7 to 9 is mainly different from the air deflection panel of the embodiment shown in fig. 1 to 6 in the shape of the drainage port, the number of the wind-raising plates, and the structure of the drainage port.
The drainage opening 515 may be cylindrical and gradually extends from the first side surface 511 to the second side surface 512 in an inclined manner toward the first end (end a) of the air deflector body 51, as shown in fig. 4, so that an included angle between the flow direction of the ambient air merged in through the flow opening 525 and the flow direction of the air supply flow is an obtuse angle, which enables the two air flows to flow in opposite directions, and the mixing effect is stronger.
Alternatively, as shown in FIG. 10, the vents 515 can be frustoconical and extend with a tapered inner diameter in the direction from the first side 511 to the second side 512. That is, the flow guide opening is gradually enlarged along the flow direction of the ambient air, which facilitates smoother mixing of the ambient air into the supply airflow.
As shown in fig. 1 to 4, the number of the wind-raising plates 52 is one, and the wind-raising plates 52 are also long, and both ends in the longitudinal direction thereof are close to both ends in the longitudinal direction of the wind deflector body 51. That is, the length of the wind-lifting plate 52 is equal to or substantially equal to the length of the wind deflector body 51, so that the wind mixing effect and the wind lifting effect are present at each position in the longitudinal direction of the wind deflector body 51.
Alternatively, the number of the wind-lifting plates 52 may be plural, and the plural wind-lifting plates 52 may be arranged at intervals along the longitudinal direction of the wind deflector body 51. For example, as shown in fig. 7 to 10, two wind-raising plates 52 are provided. The two wind-raising plates 52 can be respectively positioned on two 1/2 sections of the length direction of the wind deflector body 51. Due to the arrangement, the air raising process can be carried out on partial areas of the air deflector body 51, and the air raising is not carried out on the interval areas between the adjacent air raising plates 52, so that the air outlet direction of the interval areas in the vertical direction is different from the vertical air outlet direction of the positions where the air raising plates 52 are arranged, the whole air deflector forms a staggered air outlet effect in the vertical direction, and the air outlet range is enlarged.
One vent 515 may be associated with each louver 52. Each vent 515 can be a single opening, as in fig. 1. Alternatively, each vent 515 may include a plurality of sub-vents 5151 spaced apart from each other, as shown in FIG. 7, to enhance the appearance of the air deflection assembly 50.
The utility model also provides a wall-hanging air conditioning indoor set. Fig. 5 is a schematic view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, when an air deflector is in an upward-blowing position; fig. 6 is a schematic view showing the wall-mounted air conditioning indoor unit of fig. 4 in a state where the air guide plate is in a down-blowing position.
As shown in fig. 5, the 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 one of the embodiments. The housing 10 is provided with an air inlet (not shown) and an air outlet 12. The air deflector body 51 of the air deflector 50 is movably installed at the outlet 12.
As shown in fig. 5, the wall-mounted air conditioning indoor unit may include an evaporator (not shown), a blower 30, and a duct 40. The evaporator is used for exchanging heat with air entering the housing 10 from the air inlet to form an air supply flow (specifically, cold air during cooling and hot air during heating). The inlet of the air duct 40 faces the evaporator, and the outlet communicates with the air outlet 12. The fan 30 may be a cross-flow fan disposed at the inlet of the air duct 40 to promote air flow from the evaporator to the air outlet 12. The duct 40 may be a diffusion-end duct as shown in fig. 5, and this type of duct can realize a low pressure loss large air volume.
In some embodiments, the air deflector body 51 can rotate around a fixed axis parallel to the length direction thereof (i.e., rotate around a fixed axis) to open and close the outlet 12 and guide the outlet direction of the outlet 12. Alternatively, the air deflector body 51 may be capable of performing a planar motion, i.e., a combined motion of rotation and translation, so that the air deflector body 51 has more adjustable positions. A driving mechanism can be disposed in the casing 10, the driving mechanism includes a motor and a moving mechanism, a rotating arm can be connected to the air deflector body 51, and the rotating arm is connected to the driving mechanism to drive the air deflector body 51 to realize the aforementioned planar movement. Driving mechanisms capable of driving an object to perform a planar motion (translation + rotation) are common in the prior art, and are not described herein again.
For example, the air deflector 50 may be moved to an upward blowing position where the first side 511 faces upward and the first end (a end) faces forward, so that the air flow is guided by the first side 511 and the air deflector 52 to blow upward, as shown in fig. 5. For example, during air-conditioning cooling, the air deflector 50 may be adjusted to the above-mentioned upward blowing position, the first side 511 of the air deflector body 51 blows the supply air upward and mixes with the ambient air, and the low-temperature supply air is scattered downward after reaching the highest point, so as to realize a "shower type" cooling experience.
The air deflector 50 can be moved to a downward blowing position where the air deflector is located in front of the supply airflow and the first side 511 faces rearward and the first end (end a) faces upward, so that the supply airflow is guided downward by the air deflector 52 and the first side 511 to blow out, as shown in fig. 6. For example, when the air conditioner is heating, the air deflector 50 can be adjusted to the downward blowing position, and the first side 511 of the air deflector body 51 guides the air flow of the air supply to the bottom surface in a manner of approaching vertical direction, so as to realize the experience of heating and warming feet. In addition, a small amount of the blowing air flowing between the wind-lifting plate 52 and the wind deflector body 51 can be blown out downwards through the drainage opening 515 to form a 'plume', so that the air is prevented from being accumulated between the wind-lifting plate 52 and the wind deflector body 51.
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. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
