Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
Please refer to fig. 1 to 5, which illustrate an embodiment of an air guiding structure of an air conditioner used in a control method for blowing air by using the air guiding structure of the air conditioner. Fig. 1 is a perspective view of a part of the structure of the embodiment, specifically a perspective view including an air outlet of an indoor unit and an air guide structure; FIG. 2 is a perspective view of the back side of FIG. 1; fig. 3 is a schematic structural view of a swinging blade in a wind guide structure in a swinging state; fig. 4 and 5 are a perspective view and a sectional view, respectively, of the swing blade in this embodiment.
As shown in fig. 1 to 5, the air conditioner of this embodiment includes an indoor unit 100, the indoor unit has an air outlet 1, and a heat exchanger, a fan, an air outlet duct, and other structures are disposed inside the indoor unit 100. In the indoor unit 100, a wind guide structure is further provided near the outlet 1, specifically, between the fan and the outlet 1, for guiding the wind blown from the fan and then blowing out from the outlet 1.
Specifically, the air guide structure includes a plurality of flaps, and the flaps are arranged in a dispersed manner along the longitudinal direction of the outlet 1. Specifically, in the embodiment, the wind guiding structure includes six swinging blades, which are a first swinging blade 21, a second swinging blade 22, a third swinging blade 23, a fourth swinging blade 24, a fifth swinging blade 25 and a sixth swinging blade 26 in sequence from left to right in the figure. Moreover, the first swing blade 21, the third swing blade 23 and the fifth swing blade 25 positioned at odd-numbered positions constitute an odd-numbered swing blade group; the second, fourth and sixth swing vanes 22, 24, 26 located at even-numbered positions constitute an even-numbered swing vane group. The air guiding structure further comprises a first driving structure 27 for driving all the swing blades in the odd-numbered swing blade group to synchronously rotate, and a second driving structure 28 for driving all the swing blades in the even-numbered swing blade group to synchronously rotate.
Next, the structure of the swing blade and the connection relationship with the driving mechanism will be described by taking the swing blade 21 as an example. The swing blade 21 includes an arc cover 211 and a rotating rod 212 fixedly connected with the arc cover 211, the arc cover 211 is used as a wind guide main body, the wind guide surface is arc-shaped, and is in transmission connection with the rotating rod 212 fixedly connected with the wind guide main body, such as riveted, and the rotating rod 212 is connected with the first driving mechanism 27, and can rotate under the driving of the driving mechanism 27, so as to drive the arc cover 211 to rotate. Moreover, the opening of the arc-shaped cover 211 faces the air outlet 1 to reduce wind resistance. The other swing blades have similar structures to the swing blade 21, and also include an arc-shaped cover and a rotating rod, and the first driving mechanism 27 and the second driving mechanism 28 are respectively in transmission connection with the rotating rod corresponding to the swing blade.
More specifically, the air guide surface of the arc cover 211 is an elliptical surface formed with a notch 213. The air guide surface of the arc cover 211 is an elliptical surface, and in a relatively narrow air guide space between the air outlet 1 and the fan, the air supply angle of the elliptical surface is larger, and the air supply resistance is smaller; the notch 213 formed in the elliptical surface can prevent the arc cover 211 from colliding and interfering with other components, such as the air outlet 1, during the rotation process to limit the rotation angle of the arc cover 211 when the air guide surface is as large as possible.
Also, a plurality of through holes 214 are formed on the arc cover 211. By forming the through holes 214 on the arc-shaped cover 211, part of the air can be directly blown out through the through holes 214, and the air volume loss of the air guided out through the arc-shaped cover 211 is further reduced. Moreover, the through holes 214 can further disperse the wind, which is beneficial to realizing the weak wind sense or even no wind sense of the wind blown out from the air outlet 1, and improves the comfort of the air supply of the air conditioner.
The control method for air supply by using the air guide structure of the air conditioner in the structural form comprises the following steps of arranging the air guide structure in the indoor unit of the air conditioner and at the position close to the air outlet 1: the first driving mechanism 27 is controlled to drive the odd-numbered swing blade group to swing, and/or the second driving mechanism 28 is controlled to drive the even-numbered swing blade group to swing, and the air outlet direction of the air outlet 1 is controlled by the odd-numbered swing blade group and/or the even-numbered swing blade group.
In a preferred embodiment, the first driving mechanism 27 drives the odd-numbered oscillating vane groups to oscillate through an angle of [ -45 °, +45 ° ], and the second driving mechanism 28 drives the even-numbered oscillating vane groups to oscillate through an angle of [ -45 °, +45 ° ]. That is, all the swinging blades can swing leftwards to the maximum angle of 45 degrees and swing rightwards to the maximum angle of 45 degrees. The swinging blade swings in the swinging range, and the air outlet range of the guided wind can be enlarged on the premise of reducing the wind resistance as much as possible.
In a preferred embodiment, the method for controlling air blowing by the air guide structure of an air conditioner according to the above configuration further includes:
judging a current air supply mode according to the control instruction; the air supply mode at least comprises a comfortable air mode;
and when the current air supply mode is determined to be the comfortable air mode, controlling the first driving mechanism and the second driving mechanism to enable the swing blades in the odd-number swing blade group and the swing blades in the even-number swing blade group to rotate in opposite directions.
More preferably, when the current air supply mode is determined to be the comfortable air mode, the first driving mechanism and the second driving mechanism are controlled so that the swing blades in the odd-numbered swing blade group and the swing blades in the even-numbered swing blade group rotate in opposite directions at unequal speeds.
In the above embodiment, the flap 21 uses the arc cover 211 as the air guide main body, and the cover shape has a large air guide area and a large air guide angle. When the swing blade 21 with the structure is used as an air guide structure in an air conditioner, the air blown out from the air outlet 1 has a wider air outlet range and more dispersed air outlet, the air outlet force is weakened, the air outlet is softer, and the air outlet is comfortable when being blown to a human body. Moreover, the wind resistance of the wind guide surface of the arc-shaped cover 211 is small, the wind loss is small when wind passes through, and the wind outlet quantity at the air outlet 1 is ensured. In addition, the arc cover 211 rotates under the drive of dwang 212, has changed the position and the direction of the wind-guiding surface of arc cover 211 to, the direction of the air-out through its wind-guiding surface also can change, thereby has realized the regulation to the air-out direction. Moreover, the odd-numbered group of swing blades and the even-numbered group of swing blades are respectively controlled by one set of driving mechanism in a rotating way, so that the odd-numbered group of swing blades and the even-numbered group of swing blades can form difference in the swinging direction and the swinging speed by controlling the action direction and the action speed of each set of driving mechanism differently. For example, as shown in fig. 3, the arc-shaped covers of the odd-numbered groups of swing blades swing to the right, and the arc-shaped covers of the even-numbered groups of swing blades swing to the left. Then, air outlet channels with different widths are formed between the swing blades. The air outlet amount and the air outlet speed of the air outlet channels with different widths are different, so that air outlet forms of strong and weak air flows can be formed at the air outlet 1. If the dynamic rotation process is adopted, an air outlet mode with strong air flow and weak air flow alternating can be generated, namely a comfortable air mode. The air outlet is strong, weak different air currents blow to the human body, can realize the natural wind effect, and the air-out is soft, and the travelling comfort is strong.
In order to realize the smooth rotation of the rotating rod 212 driven by the first driving structure 27, the rotating rod 212 is a curved rod in consideration of the structure of the arc-shaped cover 211, the wind guiding effect and the limitation of the internal space of the air conditioner, and specifically, the rotating rod 212 is a curved rod formed by two straight rods which are smoothly connected through a transition arc section in the middle. And, one end of the rotating rod is fixedly connected with the middle position of the inner surface of the arc cover 211, and the other end is formed with gear teeth 2121 for engaging with the driving mechanism 22 to realize transmission. By selecting the rotating rod 212 as a curved rod of such a structure, the portion of the gear teeth 2121 is a straight rod, which facilitates forming the gear teeth 2121 and facilitating engagement with the driving mechanism; the rotating rod 212 connected with the arc-shaped cover 211 is also a long straight rod, so that the connection stability and the rotation stability are high; two parts straight-bar pass through the smooth connection of transition arc section for two sections straight-bars are in different planes, make actuating mechanism 22 and arc cover 211 be in different planar spaces, can make dwang 212 rotate when driving arc cover 211 swing on the one hand, can adjust the direction through arc cover 211 surface air-out, realize that the air-out direction is adjusted, and on the other hand is convenient for make full use of the space inside the air conditioner, before the air outlet. In order to avoid interference with another driving mechanism during rotation, a relief surface 2122 is formed on the rear surface of the gear tooth 2121 on the rotating lever on which the gear tooth 2121 is formed.
The structure of the driving mechanism and the matching relationship with the swing blades will be described below by taking the first driving mechanism 27 for driving the odd number of swing blades as an example. The first driving mechanism 27 includes a first linear rack 271, a first driving motor 272, and a transmission gear. The first straight rack 271 is transversely arranged along the arrangement direction of the swing blades and is meshed with the gear teeth on the rotating rod of each swing blade in the odd-numbered swing blade group. The shaft of the first driving motor 272 is rotationally connected with the transmission gear, the transmission gear is meshed with the first straight rack 271, and the first driving motor 272 drives the first straight rack 271 to move back and forth along the arrangement direction of the swing blades. In the moving process of the first straight rack 271, the rotating rod is driven to rotate through the meshing with the gear teeth; the dwang rotates, will drive the arc cover horizontal hunting, realizes the regulation to the air-out direction. Moreover, the length of the first straight rack 271 is greater than the distance between the two largest distances between all the swing blades in all the odd-numbered swing blade groups, and in this embodiment, greater than the distance between the first swing blade 21 and the fifth swing blade 25, so that when the first straight rack 271 moves back and forth in the arrangement direction of the swing blades, it is ensured that each swing blade in the odd-numbered swing blade group keeps meshing with the first straight rack 271 during the swing process. The structure of the second drive mechanism 28 and its cooperation with the vanes in the even-numbered vane set to be driven is described with reference to the first drive mechanism 27.
It should be noted that the first driving mechanism 27 is not limited to the above structure, and other structures that can drive the rotating rod to rotate and drive the arc cover to swing to adjust the wind direction may be used.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
