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.

Referring to fig. 1 and 2, an embodiment of the present invention is shown, specifically, fig. 1 is a perspective view illustrating a partial structure of an air conditioning indoor unit having an air guiding structure according to an embodiment of the present invention, and fig. 2 is a front view of fig. 1.

As illustrated in fig. 1 and 2, the air conditioning indoor unit 100 according to this embodiment includes an air outlet 1, and a heat exchanger, a fan, an air outlet duct, and the like are provided inside the indoor unit 100. An air guide structure 2 is further provided in the indoor unit 100 near the outlet 1, specifically, between the fan and the outlet 1 along the longitudinal direction of the outlet 1, for guiding the air blown from the fan and then blowing out from the outlet 1.

Specifically, the air guide mechanism 2 includes a rod 21 and a plurality of screw threads with different pitches formed on the rod 21, and an air guide duct is formed between two adjacent screw threads. As used herein, unequal pitches means pitches that are not completely equal or that are not completely equal. Further, in this embodiment, it is preferable that the pitches of the plurality of threads are gradually reduced from the middle portion (at the perpendicular line L) of the rod body 21 toward both left and right end portions of the rod body 21. That is, in this embodiment, the plurality of threads in the whole wind guiding structure 2 are divided into two groups, i.e., left and right groups, by using the vertical line L as a boundary, and the thread pitch of each group is symmetrical to the vertical line L where the center point of the rod body 21 is located. Taking the thread on the right side of the perpendicular line L as an example, the following is described in detail:

the right side of the vertical line L comprises five threads, a first thread 22, a second thread 23, a third thread 24, a fourth thread 25 and a fifth thread 26 are sequentially arranged from the vertical line L to the right, an air guide air duct 27 is formed between the first thread 22 and the second thread 23, and air guide air ducts are correspondingly formed between the other two adjacent threads. Moreover, the pitch between the first thread 22 and the second thread 23 is H1, the pitch between the second thread 23 and the third thread 24 is H2, the pitch between the third thread 24 and the fourth thread 25 is H3, and the pitch between the fourth thread 25 and the fifth thread 26 is H4, each pitch satisfying: h1 > H2 > H3 > H4.

In this embodiment, all the threads in the air guide structure 2 are threads having the same direction of rotation, specifically, left-handed threads.

The air guiding mechanism 2 further includes a driving mechanism 28, the driving mechanism 28 is rotatably connected to the rod 21, and the driving mechanism 28 can drive the rod 21 to rotate, specifically, the rod 21 is driven to rotate around its axis as a rotating shaft. The driving mechanism 23 may be implemented by a driving motor.

The formation of the threads on the shank 21 can be achieved in a number of different ways. For example, the rod 21 and the screw may be integrally formed or may be separately formed. If the split molding is adopted, the rod body 21 and the threads can be fixed in a welding mode; the rod body 21 and the thread 22 can also be fixed by ultrasonic welding.

By adopting the air guide mechanism 2 with the structure in the indoor unit 100, in the process of guiding the air out of the air guide air duct 23, the air is accelerated through the thread surface, so that the accelerated flow of the air guided out by the air guide mechanism 2 and sent out through the air outlet 1 is increased, the air outlet speed is increased, and the air supply distance is increased. Moreover, the air guide area of the thread surface is large, the air guide angle and range are also large, the air outlet becomes dispersed, the local air outlet force is weakened, and the air is more comfortable when being blown to a human body. Because the screw thread is the pitch that varies, and the wind-guiding width of each wind-guiding wind channel is different, and the wind speed of the wind that blows off from each wind-guiding wind channel is inequality, and the air-out of different wind speeds can be broken up wind for the air-out becomes more dispersed and can not concentrate directly to blow. For example, in this embodiment, the pitch between the threads gradually decreases from the middle of the rod body 21 to the left and right ends, the middle wind speed is low, and the wind speeds at the two ends are high, so that the wind outlet angle is increased, the wind is dispersed as much as possible, and the comfort of the outlet is further improved. The screw in the air guide mechanism 2 can also be rotated by the driving mechanism 28 in accordance with the rotation of the rod body 21. When the screw thread rotates, the speed of the wind guided out by the wind guide air duct 23 can be further increased, and the air outlet speed and the air supply distance of the air outlet 1 are further increased.

More specifically, taking the first thread 22 and the second thread 23 as an example, the structure of the threads is further described as follows:

in this embodiment, the first thread 22 includes a left thread surface 221 and a right thread surface 222, and the two thread surfaces form a closed hollow space, so that the thread 22 is formed as a hollow thread with a certain thickness, and the wind guiding resistance is smaller and the wind guiding is smoother.

Moreover, both the two thread surfaces of the thread 22 are involute thread surfaces, and the distance between the two opposite thread surfaces of two adjacent threads gradually increases from the bottom close to the rod body 21 to the outer end far away from the rod body 21. Specifically, as shown in fig. 2, the distance between the two opposite thread surfaces of the adjacent first thread 22 and second thread 23 is H1 near the bottom of the rod body 21, the distance is H1 away from the outer end of the rod body 21, H1 is greater than H1, and the change from H1 to H1 is gradually larger from bottom to top. By adopting the involute helicoid structure, the air guide surface forming the air guide duct 23 is a transition curved surface, and plays a role of dispersing the guided air. The distance between the two opposite thread surfaces is gradually increased from the bottom to the end, so that the air guide duct 23 forms an air outlet form with large bottom air speed and small end air speed from the outer end part of the bottom close to the rod body 21 in the upward and downward directions during air guide, and the air is further dispersed. After the scattered wind is blown out from the air outlet 1, the local wind power is weakened, the wind outlet is soft, the wind is blown to a human body to feel very comfortable, and the air supply comfort of the air conditioner is improved.

Fig. 3 is a front view showing a partial structure of another embodiment of an air conditioning indoor unit having an air guide structure according to the present invention.

As shown in fig. 3, in this embodiment, the air guiding structure disposed in the indoor unit of the air conditioner includes a rod 31 and a driving mechanism 32, the driving mechanism 32 is rotatably connected to the rod 31, and the driving mechanism 32 can drive the rod 31 to rotate, specifically, the driving rod 31 rotates about its axis. The drive mechanism 32 may be implemented using a drive motor.

Ten threads with unequal pitches are formed on the rod body 31, and the unequal pitches here mean that the pitches are not completely equal or the pitches are not completely equal. The ten threads are divided into a left group and a right group by taking a vertical line L where the center point of the rod body 31 is located as a boundary, five threads on the right side are all threads with the same turning direction, specifically, left-handed threads which are respectively a first thread 331, a second thread 332, a third thread 333, a fourth thread 334 and a fifth thread 335, and an air guide duct is formed between every two adjacent threads. The five threads on the left side are all threads with the same turning direction, specifically right-hand threads, namely a sixth thread 336, a seventh thread 337, an eighth thread 338, a ninth thread 339 and a tenth thread 340, and an air guide duct is formed between every two adjacent threads. In this embodiment, it is preferable that the pitches of the plurality of threads are gradually decreased from the middle portion (at the perpendicular line L) of the rod body 31 to both left and right end portions of the rod body 21, and the pitch of the left-handed threads on the right side and the pitch of the right-handed threads on the left side are also symmetrical about the perpendicular line L where the center point of the rod body 31 is located. Other configurations of threads and resulting technical effects may be found in the description of the embodiment of fig. 1.

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.
