[0002] At present, with the improvement of living standards, people have higher and higher functional requirements for air conditioners. Current air conditioners generally have a sweeping function, that is, the air outlet direction is continuously adjusted by the back-and-forth rotation of the air guide door during the air outlet process to meet user needs. However, in this process, since the air guide door is constantly rotating, the magnitude and direction of the force exerted by the air flow on the air guide door are constantly changing, which makes the air guide door easy to shake during the rotation process, and even produce abnormal noise, affecting the user experience.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] First embodiment

[0024] Please refer to Figure 1The embodiment of the utility model provides an air guide mechanism 100 for adjusting the air outlet direction. It can prevent the air guide door 120 from shaking during the rotation process, avoid abnormal noise, and improve user experience.

[0025] It should be noted that the air guide mechanism 100 is applied to an air conditioning cabinet, which is placed on the floor indoors. The air conditioning cabinet can blow hot or cold air indoors to achieve a heating or cooling function. Specifically, the air conditioning cabinet includes a fan (not shown), an air guide mechanism 100 and an evaporator (not shown). The fan is used to generate negative pressure to drive air flow and form an outlet airflow. The evaporator is used to perform heat exchange on the outlet airflow to achieve a heating or cooling function of the outlet airflow. The air guide mechanism 100 is used to guide the outlet airflow to adjust the outlet direction, thereby achieving a wind sweeping function to meet user needs.

[0026] In this embodiment, the air guide mechanism 100 is a left-right air sweeping mechanism, and the air guide mechanism 100 is used to realize the left-right air sweeping function of the air conditioner cabinet. However, it is not limited to this. In other embodiments, the air guide mechanism 100 can also be an up-down air sweeping mechanism, and the air guide mechanism 100 is used to realize the up-down air sweeping function of the air conditioner cabinet.

[0027] The air guide mechanism 100 includes an air outlet frame 110, an air guide door 120, a mounting seat 130, a driving motor 140, a transmission assembly 150 and an elastic member 160. The mounting seat 130 is fixedly connected to the air outlet frame 110, and the air outlet frame 110 is used to carry and fix the mounting seat 130. The driving motor 140 is mounted on the mounting seat 130 and connected to the air guide door 120 through the transmission assembly 150. The mounting seat 130 is used to fix the driving motor 140, and the driving motor 140 is used to drive the air guide door 120 to rotate through the transmission assembly 150 to realize the air sweeping function of the air conditioner cabinet. The air guide door 120 is rotatably mounted in the air outlet frame 110, and the air guide door 120 can rotate relative to the air outlet frame 110. The air outlet frame 110 can limit the air guide door 120 to ensure the stability of the rotation of the air guide door 120. The transmission assembly 150 is rotatably matched with the mounting seat 130, and the mounting seat 130 can limit the transmission assembly 150 to ensure the stability of the transmission assembly 150 during transmission. Specifically, the transmission assembly 150 and the elastic member 160 are both arranged between the mounting seat 130 and the air outlet frame 110, and the elastic member 160 abuts against the transmission assembly 150. The elastic member 160 is used to press the transmission assembly 150 on the mounting seat 130 or the air outlet frame 110 to increase the friction between the transmission assembly 150 and the mounting seat 130 or the air outlet frame 110, thereby increasing the resistance of the transmission assembly 150 during transmission, and then increasing the resistance of the air guide door 120 during rotation. The resistance can suppress the air guide door 120 from shaking under the wind force of the air outlet airflow, thereby preventing the air guide door 120 from shaking during rotation, avoiding abnormal noise, and improving user experience.

[0028] Please refer to Figures 2 to 4The transmission assembly 150 includes a motor crank 151, a connecting rod 152 and a transmission crank 153. One end of the motor crank 151 is hinged to the driving motor 140, and the other end is hinged to the connecting rod 152. The motor crank 151 can rotate relative to the output shaft of the driving motor 140 and relative to the connecting rod 152. The driving motor 140 can drive the connecting rod 152 to move through the motor crank 151. The transmission crank 153 is rotatably mounted on the air outlet frame 110 and is hinged to the connecting rod 152. The transmission crank 153 can rotate relative to the air outlet frame 110. The air outlet frame 110 can limit the transmission crank 153. The connecting rod 152 can drive the transmission crank 153 to rotate under the action of the driving motor 140. One end of the transmission crank 153 cooperates with the air guide door 120, and the other end is rotatably connected to the mounting seat 130. The mounting seat 130 can limit the transmission crank 153, and the transmission crank 153 can drive the air guide door 120 to rotate to achieve the wind sweeping function. In this way, the air outlet frame 110 and the mounting seat 130 work together to limit the transmission crank 153 at the same time, further improving the stability of the transmission crank 153 during the rotation process, and ensuring that the transmission process is stable and reliable.

[0029] Specifically, the elastic member 160 abuts against the transmission crank 153, and the elastic member 160 can press the transmission crank 153 against the mounting seat 130 or the air outlet frame 110 to increase the friction between the transmission crank 153 and the mounting seat 130 or the air outlet frame 110, thereby increasing the resistance encountered by the transmission crank 153 during the transmission process, and further increasing the resistance encountered by the air guide door 120 during the rotation process, thereby preventing the air guide door 120 from shaking during the rotation process.

[0030] In this embodiment, one end of the elastic member 160 abuts against the transmission crank 153, and the other end abuts against the mounting seat 130. The elastic member 160 is used to press the transmission crank 153 against the air outlet frame 110 to increase the friction between the transmission crank 153 and the air outlet frame 110, thereby preventing the air guide door 120 from shaking during the rotation process. However, this is not limited to this. In other embodiments, one end of the elastic member 160 abuts against the transmission crank 153, and the other end abuts against the air outlet frame 110. The elastic member 160 is used to press the transmission crank 153 against the mounting seat 130 to increase the friction between the transmission crank 153 and the mounting seat 130, which can also prevent the air guide door 120 from shaking during the rotation process.

[0031] The transmission crank 153 includes a matching column 1531, a supporting ring 1532 and an extension arm 1533. The supporting ring 1532 is sleeved outside the circumference of the matching column 1531 and is fixedly connected to the matching column 1531. One end of the extension arm 1533 is fixedly connected to the supporting ring 1532 and the other end is hinged to the connecting rod 152. The extension arm 1533 can rotate relative to the connecting rod 152, thereby driving the entire transmission crank 153 to rotate relative to the connecting rod 152. In this embodiment, the matching column 1531, the supporting ring 1532 and the extension arm 1533 are integrally formed to improve the connection strength.

[0032] Specifically, one end of the matching column 1531 matches with the air guide door 120, and the other end is rotatably connected with the mounting seat 130. The matching column 1531 can rotate relative to the mounting seat 130, and synchronously drive the air guide door 120 to rotate relative to the air outlet frame 110 during the rotation process. The mounting seat 130 can limit the matching column 1531 to ensure the stability of the rotation of the matching column 1531. The elastic member 160 is sleeved outside the matching column 1531, one end of the elastic member 160 abuts against the abutting ring 1532, and the other end abuts against the mounting seat 130. The elastic member 160 is always in a compressed state. The elastic member 160 can apply elastic force to the abutting ring 1532, so that the entire transmission crank 153 has a tendency to approach the air outlet frame 110, thereby increasing the friction between the transmission crank 153 and the air outlet frame 110, and preventing the air guide door 120 from shaking during the rotation process.

[0033] In this embodiment, the elastic member 160 is a spring, but it is not limited thereto. In other embodiments, the elastic member 160 may be elastic rubber or elastic silicone, and the material of the elastic member 160 is not specifically limited.

[0034] It is worth noting that the mounting seat 130 is provided with a limiting groove 131, and the matching column 1531 extends into the limiting groove 131 and is rotatably matched with the limiting groove 131. The matching column 1531 can rotate relative to the limiting groove 131, and the limiting groove 131 can limit the matching column 1531. The elastic member 160 abuts against the side wall of the limiting groove 131, and the side wall of the limiting groove 131 can apply elastic force to the abutting ring 1532 through the elastic member 160, so as to press the entire transmission crank 153 on the air outlet frame 110, thereby increasing the friction between the transmission crank 153 and the air outlet frame 110.

[0035] Furthermore, the air outlet frame 110 is provided with a clearance hole 111, and the matching column 1531 is arranged through the clearance hole 111 and is rotatably matched with the clearance hole 111. The matching column 1531 can rotate relative to the clearance hole 111, and the air outlet frame 110 can limit the matching column 1531 through the clearance hole 111. The abutting ring 1532 abuts against the air outlet frame 110, that is, the outer diameter of the abutting ring 1532 is larger than the aperture of the clearance hole 111, so as to prevent the transmission crank 153 from falling off the air outlet frame 110. The abutting ring 1532 can be tightly fitted with the air outlet frame 110 under the action of the elastic member 160 to increase the friction between the transmission crank 153 and the air outlet frame 110.

[0036] Preferably, a weight-reducing groove 1534 is provided at one end of the mating column 1531 close to the mounting seat 130. On the one hand, the provision of the weight-reducing groove 1534 can reduce the weight of the entire transmission crank 153 and save material costs; on the other hand, the provision of the weight-reducing groove 1534 can facilitate injection molding of the transmission crank 153 and avoid appearance defects of the transmission crank 153.

[0037] In this embodiment, the number of the transmission cranks 153, the air guide doors 120 and the elastic members 160 are all two, each elastic member 160 is abutted against a transmission crank 153, each transmission crank 153 cooperates with an air guide door 120, the two transmission cranks 153 are arranged at intervals, and are both hinged to the connecting rod 152.
