Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air-conditioning air guide structure and an air conditioner. Background Art

[0002] In the prior art, in order to adjust the left and right air outlet direction of the air outlet of the air conditioner indoor unit, it is often achieved by adding a plurality of small air guides that can swing left and right at the air outlet. However, when setting the small air guides, in order not to affect the adjustment of the original large air guide plate of the air outlet, the installation position of the small air guides must be moved inward.

DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0022] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “front”, “rear”, “left”, “right”, “up”, “down”, and “inside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] like Figures 1 to 4As shown, the air-conditioning air guide structure disclosed in the present invention improves the air guide plate 300 arranged at the air outlet 200 of the existing air-conditioning indoor unit 100, and the air guide plate 300 adjusts the air outlet volume and air outlet direction of the air outlet 200 by its own rotation. The present invention adds a main swing blade assembly 410, a left swing blade assembly 420 and a right swing blade assembly 430 to the air guide plate 300 to achieve the effect of guiding the airflow at the air outlet 200 to the left and right sides of the air outlet 200.

[0024] like Figure 1 and Figure 2 As shown, the main swing blade assembly 410 added in the present invention is slidably matched with the air guide plate 300 and the sliding direction of the main swing blade assembly 410 is consistent with the length direction of the air guide plate 300, and the two ends of the main swing blade assembly 410 are respectively hinged to the left swing blade assembly 420 and the right swing blade assembly 430, and at the same time, the ends of the left swing blade assembly 420 and the right swing blade assembly 430 that are not connected to the main swing blade assembly 410 are slidably matched with the air guide plate 300; a plurality of rotatable swing blades 440 are provided on the main swing blade assembly 410, the left swing blade assembly 420 and the right swing blade assembly 430.

[0025] When the air outlet 200 is guided, Figure 1 As shown, the main swing blade assembly 410 translates toward the right end of the air guide plate 300, i.e., the right swing blade assembly 430. The left swing blade assembly 420 is stretched to a certain tilt angle under the pull of the main swing blade assembly 410. The swing blades 440 on the left swing blade assembly 420 rotate to form multiple air outlet channels on the left side of the air guide plate 300, while the swing blades 440 on the right swing blade assembly 430 on the right side of the air guide plate 300 do not rotate, so that the right side of the air guide plate 300 is closed and air cannot flow. In addition to being guided by the air guide plate 300, the airflow exhausted by the air conditioner indoor unit 100 will also flow to the left side of the air guide plate 300 under the guidance of the left swing blade assembly 420, thereby achieving wide-area air supply on the left side of the air conditioner. Figure 2 As shown, the main swing blade assembly 410 translates toward the left end of the air guide plate 300, i.e., the left swing blade assembly 420, and the right swing blade assembly 430 is stretched to a certain tilt angle under the pull of the main swing blade assembly 410. The swing blade 440 on the right swing blade assembly 430 rotates to form a plurality of air outlet channels on the right side of the air guide plate 300, while the swing blade 440 on the left swing blade assembly 420 on the left side of the air guide plate 300 does not rotate, so that the left side of the air guide plate 300 is closed and air cannot flow. In addition to the air guide of the air guide plate 300, the airflow discharged from the air-conditioning indoor unit 100 will also flow to the right side of the air guide plate 300 under the guidance of the right swing blade assembly 430, thereby realizing wide-area air supply on the right side of the air conditioner.

[0026] like Figure 1 and Figure 2As shown, the translation of the main swing blade assembly 410 in the present invention is driven by the cooperation of the driving motor 413 and the screw 414, and the main connecting rod 411 and the main slide 412 are cooperated to realize the sliding of the main swing blade assembly 410 on the air guide plate 300. The main slide 412 is fixed on the air guide plate 300 and extends toward the two ends of the air guide plate 300 along the length direction of the air guide plate 300. The swing blade of the main swing blade assembly 410 is rotatably arranged on the main connecting rod 411, and the main connecting rod 411 is slidably matched with the main slide 412, that is, the main connecting rod 411 can slide along the main slide 412; the two ends of the main connecting rod 411 are respectively hinged to the left swing blade assembly 420 and the right swing blade assembly 430 through hinges or similar connection structures. The driving motor 413 is fixed on the air deflector 300, and the screw 414 is connected between the main connecting rod 411 and the driving motor 413. Specifically, one end of the screw 414 is connected to the output end of the driving motor 413, and an internal threaded hole is axially provided at one end of the main connecting rod 411 connected to the screw 414 so as to be threadedly matched with the external thread on the outer peripheral surface of the screw 414. When the driving motor 413 is working, the screw 414 is driven to rotate together. When the screw 414 rotates, the main connecting rod 411 and the screw 414 are relatively displaced, thereby realizing the translation of the main connecting rod 411 along the main slide 412 on the air deflector 300.

[0027] The left swing blade assembly 42 used in the present invention is as follows Figure 1 and Figure 2 As shown, it is composed of a left connecting rod 412, a left slide groove 422 and a left slider 423, wherein the left slide groove 422 is a groove-shaped structure set on the air guide plate 300, and the left slider 423 is embedded in the left slide groove 422 to achieve sliding cooperation with the left slide groove 422, so that the left slider 423 can slide in the left slide groove 422. The two ends of the left connecting rod 412 are respectively hinged to the main connecting rod 411 and the left slider 423 through hinges or similar connection structures, and the swing blade of the left swing blade assembly 420 is rotatably set on the left connecting rod 412. Similarly, the right swing blade assembly 430 used in this invention is as shown in FIG. Figure 1 and Figure 2 As shown, it is composed of a right connecting rod 431, a right slide groove 432 and a right slider 433, wherein the right slide groove 432 is a groove-shaped structure set on the air guide plate 300, and the right slider 433 is embedded in the right slide groove 432 to achieve sliding cooperation with the right slide groove 432, so that the right slider 433 can slide in the right slide groove 432. The two ends of the right connecting rod 431 are respectively hinged to the main connecting rod 411 and the right slider 433 through hinges or similar connection structures, and the swing blade of the right swing blade assembly 430 is rotatably set on the right connecting rod 431. The extension direction of the left slide groove 422 and the right slide groove 432 is perpendicular to the extension direction of the main slide groove 412 from the same side, as shown in FIG. Figure 1 and Figure 2 As shown, the left slide groove 422 and the right slide groove 432 in the present invention are also located above the main slide groove 412 .

[0028] Furthermore, the left slide groove 422 and the right slide groove 432 are located on the same horizontal line, so that the left slide groove 422 and the right slide groove 432 remain horizontal, so that the left swing blade assembly 420 and the right swing blade assembly 430 can have the same inclination angle range, which is beneficial to control the air volume and air outlet direction on both sides of the air conditioner. The spacing between the left slide groove 422 and the right slide groove 432 is preferably greater than the length of the main connecting rod 411.

[0029] In the present invention, the swing blade 440 guides the airflow by rotating itself, and the rotation of the swing blade 440 is driven by the driving mechanism. The main swing blade assembly 410, the left swing blade assembly 420 and the right swing blade assembly 430 are all provided with a driving mechanism for driving the corresponding swing blade 440 to rotate. The driving mechanism can adopt a crank connecting rod mechanism, a gear rack driving mechanism or a motor driving mechanism, or the user can manually turn the swing blade 440 to rotate the swing blade 440. The swing blade 440 is connected to the corresponding driving mechanism through the swing blade mechanism commonly used in the air conditioner, and the synchronous rotation of the swing blade 440 on each swing blade assembly is realized through the driving mechanism.

[0030] like Figure 3 and Figure 4 As shown, the air guide plate 300 is rotatably arranged in the air outlet 200 of the air-conditioning indoor unit 100, and the air guide plate 300 realizes the closing and opening of the air outlet 200 by its own rotation; the main swing blade assembly 410, the left swing blade assembly 420 and the right swing blade assembly 430 are all arranged on the inner side surface of the air guide plate 300, that is, the side of the air guide plate 300 facing the inside of the air-conditioning indoor unit 100. The rotatable connection of the air guide plate 300 on the air conditioner indoor unit 100 is achieved by the cooperation of the air guide plate slide 310 and the rotating shaft 320. The two air guide plate slides 310 are distributed and fixed at the two end ends of the air guide plate 300, and the air guide plate slides 310 extend along the width direction of the air guide plate 300; the two rotating shafts 320 that cooperate with the air guide plate slides 310 are respectively fixed at the two ends of the air outlet 200 of the air conditioner indoor unit 100, and the two rotating shafts 320 are respectively inserted into the corresponding air guide plate slides 310, so that the air guide plate 300 can rotate under the drive of the air guide plate driving mechanism. The air guide structure of the air conditioner in the present invention moves synchronously with the rotation of the air guide plate 300. When the air conditioner is working, the air guide plate 300 can guide the air outlet of the air conditioner laterally and further guide the air outlet longitudinally. At the same time, since the air guide structure of the air conditioner moves as a whole with the air guide plate 300, the air outlet on both sides of the air guide plate 300 will not be restricted by the side walls of the air outlet 200, thereby achieving three-dimensional wide-area air supply with a wider range and smoother air outlet, effectively improving the air outlet effect.

[0031] The invention also discloses an air conditioner provided with the air conditioning air guide structure.
