Detailed Description
The technical scheme provided by the invention is described in more detail below with reference to fig. 1 to 5.
Referring to fig. 1 to 5, an embodiment of the present invention provides an air port structure including a frame 1, a closing plate 2, and a wind-sweeping blade 3. The frame body 1 is arranged on the installation base body or the internal machine; the wind-sweeping blade 3 is arranged on the closing plate 2 or the frame body 1, and the closing plate 2 is connected with the frame body 1. When the closing plate 2 is at the first working position, the closing plate 2 seals the air outlet 11 of the frame body 1; when the closing plate 2 is in the second operating position, the closing plate 2 is moved to a position where the air outlet 11 of the frame 1 is opened.
The mounting substrate includes a suspended ceiling. The frame 1 may be mounted to a suspended ceiling, in particular, may be directly mounted to a suspended ceiling. The tuyere structure can be used for a central air conditioner and the like. The internal machine body can be an internal machine of a central air conditioner.
The first working position is a position for closing the air outlet 11; the second working position can be preset according to the required up-down air outlet direction.
The air port structure mainly comprises a frame body 1, a closing plate 2 and an air sweeping blade 3, and the opening and closing of an air outlet 11 of the frame body 1 are realized through the closing plate 2. When the air outlet 11 is in an open state, the air sweeping blade 3 is positioned on the air outlet flow passage; when the air outlet 11 is in a closed state, the air sweeping blade 3 is positioned in a cavity enclosed by the frame body 1 and the closing plate 2. During the opening and closing process of the air outlet 11, the wind sweeping blade 3 can move relative to the frame body 1 to change the relative positions of the wind sweeping blade 3 and the frame body 1; the relative positions of the wind sweeping blades 3 and the frame body 1 can not be moved or changed. When the wind-sweeping blade 3 is arranged on the closing plate 2, the position of the closing plate 2 moves to change the relative position of the wind-sweeping blade 3 and the frame body 1, the wind-sweeping blade 3 moves along with the movement of the closing plate 2, and then left and right wind-sweeping is realized at the moved position. When the wind sweeping blade 3 is arranged on the frame body 1, the relative position of the wind sweeping blade 3 and the frame body 1 is unchanged, and the wind sweeping blade 3 sweeps wind left and right at a determined position.
According to the technical scheme, the air sweeping blade 3 is directly arranged on the closing plate 2, and the direction of air flow of the air conditioner is changed only by using the movement of one part of the closing plate 2. The single component is simpler in design, and interference of other parts is avoided in movement; resources can be saved, and the production efficiency can be improved during assembly; and the use of one moving part is reduced, so that the whole weight of the tuyere part is directly lightened, and the service life of the tuyere part is prolonged. In terms of cleaning, the design of the single closure plate 2 facilitates the cleaning of the tuyere by the user, reducing the burden on the user. The maintenance is convenient in after-sale maintenance. The function of the closing plate 2 and the wind sweeping blade 3 can be realized at the same time of beautiful atmosphere, the reliability is more convincing, and the use is convenient for users.
Optionally, the closing plate 2 is rotatably connected to the frame 1.
In the present embodiment, when the closing plate 2 is moved from the first operating position to the second operating position, the closing plate 2 is rotated in a direction away from the frame body 1.
A number of alternative constructions of the closure plate 2 are described below.
Referring to fig. 5, one of the structures is: the closure plate 2 comprises a guide surface 24, the guide surface 24 being arcuate. In the cross section of the closure plate 2, the flow guiding surface 24 comprises a first segment of arc 241 and a second segment of arc 242 which are smoothly transited and have different bending directions. Wherein the flow guiding surface 24 is used for guiding flow when the closure plate 2 is in the second operating position.
Referring to FIG. 5, point A generally illustrates the demarcation point of the first segment arc 241 and the second segment arc 242. The air flow first contacts the first segment of arc 241, then changes direction, and then flows to the second segment of arc 242. Because the bending directions of the first section arc 241 and the second section arc 242 are different, the direction of the air flow flowing out of the air outlet 11 is related to the bending direction of the second section arc 242, and compared with the scheme without the second section arc 242, the air flow flowing out range of the second section arc 242 is larger, and the heat exchange effect is better.
Alternatively, when the closure plate 2 is in the second operating position, the tangential direction of both the first segment of arc 241 and the second segment of arc 242 is substantially parallel to the direction of the air flow into the air intake 12 of the housing 1. This also allows a greater range of airflow out of the outlet 11.
In this embodiment, the arc length of the first segment arc 241 is longer than the arc length of the second segment arc 242. The first segment of arc 241 can realize air flow buffering, and the second segment of arc 242 can change the air flow direction flowing along the first segment of arc 242, so that large-range air outlet is realized.
The radius of the first section of arc 241 is greater than that of the second section of arc 242, so that the corresponding central angle of the second section of arc 242 is greater and the air outlet range is greater when the arc length is the same.
Referring to fig. 3 and 4, another possible configuration of the closure plate 2 is described below. Referring to fig. 3, the closing plate 2 includes a first plate 22 forming the cavity 21 and a second plate 23, the wind-sweeping blade 3 being provided on the first plate 22, the side of the second plate 23 facing away from the first plate 22 being a flat plate. When the closure plate 2 is in the first operating position, the side of the second plate 23 facing away from the first plate 22 is flush with the bottom surface of the frame 1.
The closed plate 2 is composed of an upper layer and a lower layer, the middle of the assembled closed plate is in a hollow state, a certain number of wind sweeping blades 3 are evenly arranged on the closed plate 2, and in order to achieve the left and right wind sweeping functions, the wind sweeping blades 3 are connected with a stepping motor through wind sweeping connecting rods, and the left and right wind sweeping functions of the air conditioner are achieved.
Alternatively, the first plate 22 is arcuate and concave arcuate. The structure can play a buffering role on the air flow, can play a guiding role on the air flow, ensures that the outflow direction of the air flow which goes out through the air sweeping blade 3 is reasonable, and avoids discomfort caused by direct blowing to a human body.
Specifically, referring to fig. 3, the first plate 22 is arc-shaped, and in a cross section of the first plate 22, a middle portion of the first plate 22 is lower than both ends of the first plate 22. The first plate 22 has the same flow guiding function as the flow guiding surface 24 described above toward the inside of the frame 1, i.e., toward the side of the air intake 12. The first plate 22 of the closure plate 2 is designed to be arc-shaped, so that the direction of the air flow can be easily changed, and the flow guiding effect is good.
The cross-section of the closed and open states of the tuyere structure is shown in fig. 3 and 4, the closed plate 2 comprises a first plate 22 and a second plate 23, the first plate 22 has a certain radian design, and the radian is bent downwards, so that on one hand, the interference problem between the wind sweeping blades 3 and the first plate 22 when sweeping wind left and right can be avoided, on the other hand, the smooth radian design can well control the trend of air flow of an air conditioner, and cold wind is settled downwards through the radian of the first plate 22, so that the discomfort of direct blowing to a human body is avoided. The lower closing plate 2 is designed into a flat surface, and the closing plate 2 can be horizontally attached to the wall surface when the air conditioner is closed.
For better insulation, the cavity 21 is filled with a layer of insulating material. After the heat insulation material layer is arranged, the condensation preventing effect of the closing plate 2 is better.
In this embodiment, the wind-sweeping blades 3 are arranged in rows on the closing plate 2.
If the tuyere is of a relatively long length, the closure plate 2 may optionally comprise two or more closure plates 2, each of the closure plates 2 being arranged side by side.
If the tuyere structure is long, two or more closure plates 2 may be used, the closure plates 2 will remain synchronized and relatively parallel during movement and will not interfere with the movement.
Optionally, when the closing plate 2 is in the second working position, the closing plate 2 moves to a position where the extension surface of the closing plate 2 is inclined to the height direction of the frame 1 to open the air outlet 11 of the frame 1, and the closing plate 2 can guide air up and down. In this position, the closure plate 2 can simultaneously serve an up-and-down flow guiding function.
Another possible arrangement of the wind blade 3 is: the wind-sweeping blade 3 is arranged on the frame body 1, and the closing plate 2 is also arranged on the frame body 1. The rotatable connection part of the wind sweeping blade 3 and the frame body 1 and the rotatable connection part of the closing plate 2 and the frame body 1 are respectively positioned at two opposite sides of the frame body 1. I.e. the wind-sweeping blade 3 is arranged at one side of the frame 1 and the closing plate 2 is arranged at the other side of the frame. The wind sweeping blade 3 and the closing plate 2 can be directly arranged on the side edge or near the side edge, and the structure completely separates the closing plate 2 serving as an upper wind sweeping component and a lower wind sweeping component from the wind sweeping blade 3 serving as a left wind sweeping component and a right wind sweeping component, so that the installation design is more efficient.
The air port structure is embedded in the wall surface in a closed state as shown in fig. 1, so that when the air conditioner does not work, the air outlet 11 is attached to the wall surface and is in near seamless connection, and fine fusion of the air port structure and a building is realized; meanwhile, the invisible design of the air port structure is suitable for various home decoration styles, the close fitting design enables home decoration to be more complete, the unique air port design is realized, an overhaul port is not required to be reserved, and an air conditioner is directly overhauled from the air outlet 11, so that the air port structure is convenient to disassemble and assemble.
The opening state of the tuyere structure is shown in fig. 2, and the stepping motor of the closing plate 2 is slowly opened when receiving the opening electric signal. Meanwhile, the stepping motor of the wind sweeping blade 3 is started to drive the wind sweeping blade 3 to sweep wind left and right. From the motion process, the motion of the structural parts of the single closing plate 2 can be more reliable, and the function of sweeping wind up and down can be realized only through the closing plate 2.
Referring to fig. 1, the air outlet 11 is located at the bottom of the frame 1, the design of lower air supply is matched with the intelligent air sweeping design, and the closing plate 2 can be adjusted by 0-90 degrees, so that the air supply functions in different directions are realized.
The embodiment of the invention also provides a central air conditioner which comprises the air port structure provided by any technical scheme of the invention.
