For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Current air conditioners are usually equipped with an air guide door at the air outlet. The air guide door closes the air outlet when the air conditioner is turned off to prevent dust accumulation. The air guide door can also open the air outlet when the air conditioner is running and guide the outlet airflow, thereby improving the user's physical comfort.

[0046] However, the existing air guide door has an assembly gap and is affected by the wind force during the opening process, which leads to unstable force on the air guide door. The assembly gap of the driving mechanism jumps from one side of the rotation axis to the other side, causing the air guide door to shake or jump greatly during the rotation process, which not only affects the air supply effect, but also reduces the user experience.

[0047] Based on the above problems, the utility model provides an air conditioner, which generally includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by a pipeline, wherein the indoor unit includes an air guide mechanism.

[0048] See also Figures 1 to 6 The air guide mechanism 10 includes a base 100 , an air guide door 200 , a driving member 300 , a transmission connecting rod 400 and a pre-tightening member 500 .

[0049] It can be understood that the base 100 is provided with an air outlet, and the air guide door 200 is rotatably arranged on the base 100; the driving member 300 is arranged on the base 100, and the transmission connecting rod 400 is connected to the output end of the driving member 300 and connected to the air guide door 200, and is used to drive the air guide door 200 to rotate relative to the base 100 under the drive of the driving member 300, and the pre-tightening member 500 is used to provide the air guide door 200 with a pre-tightening force opposite to the opening direction of the air guide door 200, or to provide the air guide door 200 with the same pre-tightening force along the closing direction of the air guide door 200.

[0050] In this embodiment, one end of the pre-tightening member 500 is connected to the transmission connecting rod 400 so that the air guide door 200 has a movement tendency of opening or closing. That is to say, by arranging the pre-tightening member 500 on the transmission connecting rod 400 and making the pre-tightening member 500 in a deformed state, a pre-tightening force is applied to the transmission connecting rod 400 through the pre-tightening member 500, so that when the driving member 300 drives the transmission connecting rod 400 to drive the air guide door 200 to open, the pre-tightening member 500 provides the air guide door 200 with a reverse force to the opening of the air guide door 200, that is, a resistance is provided to the air guide door 200 during the opening process, and the pre-tightening resistance is The maximum opening degree of the air guide door 200 is reached when the door 200 is opened to the maximum; and when the driving member 300 drives the transmission connecting rod 400 to drive the air guide door 200 to close, the preload member 500 provides the air guide door 200 with a force in the same direction as the closing of the air guide door 200, that is, during the closing process, a preload assist is provided to the air guide door for reversing the closing direction of the air guide door, so that even if there is an assembly gap between the transmission connecting rod 400 and the air guide door 200 and the base 100, there is no virtual position, thereby ensuring that the force on the air guide door 200 is relatively stable during the movement, thereby avoiding the air guide door 200 from getting stuck, shaking or jumping, thereby improving the user experience.

[0051] In detail, since the two ends of the pre-tightening member 500 are respectively fixedly connected to the transmission connecting rod 400 and the base 100, when the driving member 300 drives the air guide door 200 to open, the pre-tightening member 500 is in a twisted state, and the pre-tightening member 500 generates an elastic restoring force to act on the transmission connecting rod 400, so as to apply a moment in the closing direction to the air guide door 200, and make the assembly gap of the air guide door 200 and the transmission mechanism located on the same side, and when the air guide door 200 rotates to the side opposite to the force of the wind, since there is no virtual position, the air guide door 200 will not jump due to the virtual position reversal;

[0052] When the driving member 300 drives the air guide door 200 to close, the torque in the closing direction applied by the preload member 500 to the air guide door 200 through the transmission link 400 is minimal. That is to say, the preload member 500 acts on the transmission mechanism to always apply a closing torque to the air guide door 200, thereby always providing a preload force thereto. Moreover, since the preload member 500 and the driving member 300 output torque directions are consistent when closed, the assembly gap between the air guide door 200 and the transmission mechanism is always on one side of the rotating shaft 433. Therefore, there is no virtual position, thereby avoiding problems such as jamming and jumping of the air guide door 200 during movement.

[0053] Of course, when the pre-tightening member 500 is in a twisted state, the transmission connecting rod 400 can also always apply a torque in the opening direction to the air guide door 200. The principle is the same as above and will not be repeated here.

[0054] Furthermore, the transmission connecting rod 400 includes a driving crank 410, a first connecting rod 420 and a transmission crank 430 connected in sequence, the driving crank 410 is connected to the output end of the driving member 300, the transmission crank 430 is connected to the air guide door 200, one end of the preload member 500 is connected to the transmission crank 430, and the other end is connected to the base 100.

[0055] In this embodiment, the driving member 300 is a motor, which drives the driving crank 410 to rotate, and the driving crank 410 drives the transmission crank 430 to rotate, and finally the transmission crank 430 drives the air guide door 200 to rotate, so that the air guide door 200 opens or closes the air outlet; and the transmission connecting rod 400 composed of the driving crank 410, the first connecting rod 420 and the transmission crank 430 has a stable structure and can drive the air guide door 200 to rotate stably.

[0056] Furthermore, the transmission crank 430 is provided with a first clamping column 431, the base 100 is provided with a second clamping column 110, and the two ends of the preload member 500 are respectively provided with a first hook 510 and a second hook 520, the first hook 510 is connected to the first clamping column 431, and the second hook 520 is connected to the second clamping column 110.

[0057] In this embodiment, the preload member 500 is a torsion spring, and the torsion spring is in a preloaded state when installed. Therefore, by clamping one end of the torsion spring to the first clamping column 431 of the transmission crank 430 and the other end to the second clamping column 110 on the base 100, the torsion spring always applies a preload force to the transmission drive, so that the air guide door 200 has a tendency to open or close.

[0058] Furthermore, the transmission crank 430 is also provided with a mounting column 432 , and the preload member 500 is sleeved outside the mounting column 432 .

[0059] In this embodiment, the pre-tightening member 500 is sleeved on the mounting column 432 of the driving crank 430 to limit the pre-tightening member 500 .

[0060] Furthermore, the base 100 is provided with a mounting hole 120 , and the transmission crank 430 is provided with a rotating shaft 433 , the rotating shaft 433 is movably provided in the mounting hole 120 , and the axis of the rotating shaft 433 and the axis of the mounting column 432 are located in the same straight line.

[0061] In this embodiment, the mounting column 432 is arranged coaxially with the rotating shaft 433, so that when the transmission crank 430 rotates around the axis of the rotating shaft 433, the preload member 500 also produces elastic deformation centered on the axis of the mounting column 432, thereby ensuring that the elastic restoring force generated by the preload member 500 is better applied to the transmission crank 430.

[0062] Furthermore, a clamping portion 434 is provided at the end of the rotating shaft 433 , and the clamping portion 434 is detachably connected to the air guide door 200 .

[0063] In this embodiment, the holding portion 434 is passed through the mounting hole 120 , the rotating shaft 433 is located in the mounting hole 120 , and the holding portion 434 is engaged with the air guide door 200 , so that the air guide door 200 can be easily installed or removed.

[0064] Furthermore, the air guide mechanism 10 also includes a motor base 600 , which is connected to the base 100 , the driving member 300 is disposed on the motor base 600 , the motor base 600 is provided with a mounting groove 610 , and one end of the mounting column 432 away from the base 100 is embedded in the mounting groove 610 .

[0065] In this embodiment, since the preload member 500 is sleeved in the mounting column 432, by docking the mounting groove 610 of the motor seat 600 with the end of the mounting column 432, on the one hand, the installation stability of the motor seat 600 can be improved; on the other hand, it can also play a limiting role on the preload member 500 to prevent the preload member 500 from falling off the mounting column 432.

[0066] Furthermore, there are multiple air guide doors 200 and multiple transmission cranks 430, and the transmission connecting rod 400 also includes a second connecting rod 440 connected to the first connecting rod 420. The multiple air guide doors 200 are connected to the multiple transmission cranks 430 in a one-to-one correspondence, and the multiple transmission cranks 430 are connected through the second connecting rod 440.

[0067] In this embodiment, a plurality of transmission cranks 430 are provided to realize a multi-air guide door 200 structure of the air guide mechanism 10 .

[0068] In practical applications, double air guide doors 200 are usually used, that is, the number of air guide doors 200 and the number of transmission cranks 430 are both two, so that the two air guide doors 200 are driven to open or close synchronously through the first connecting rod 420, the second connecting rod 440 and the two transmission cranks 430.

[0069] It should be noted that the first connecting rod 420 and the second connecting rod 440 are integrally formed.

[0070] It is understandable that the transmission crank 430 is also detachably connected to the first connecting rod 420 and the second connecting rod 440 to facilitate the disassembly, maintenance or replacement of the transmission mechanism.

[0071] Furthermore, in order to accommodate multiple air guide doors 200, the number of pre-tightening members 500 is also multiple. By providing pre-tightening members 500 on multiple transmission cranks 430, multiple transmission cranks 430 are subjected to the elastic restoring force of the pre-tightening members 500 during rotation, thereby making the movement of the entire air guide mechanism 10 more stable.

[0072] In summary, the utility model provides an air guide mechanism 10 and an air conditioner, by arranging a preload member 500 on the transmission link 400 and making the preload member 500 in a deformed state, so as to apply a preload force to the transmission link 400 through the preload member 500, so that when the driving member 300 drives the transmission link 400 to drive the air guide door 200 to open or close, there is no virtual position between the transmission link 400 and the air guide door 200 relative to the base 100 even if there is an assembly gap, thereby ensuring that the air guide door 200 is subjected to relatively stable force during movement, thereby avoiding the air guide door 200 from getting stuck, shaking or jumping, thereby improving the user experience.

[0073] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
