Description
Technical Field
[0001] This application relates to the field of air conditioning technology, such as a motion mechanism for an air guide plate of an air conditioning indoor unit and an air conditioner. Background Technology
[0002] Currently, air conditioners are a very common appliance, widely used in various living and working environments such as homes, offices, and shopping malls. For example, existing air conditioner indoor units have large guide plates installed at the air outlet to achieve air delivery over longer distances, improving the airflow effect and comfort of the indoor unit, which is welcomed by users.
[0003] In existing structures, a motion mechanism is used to drive the extension and rotation of the air guide plate, so that the air guide plate can guide air in different directions and at different angles. For example, in existing motion mechanisms for air guide plates, there is a driving member for moving the air guide plate to a preset position and another driving member for driving the air guide plate to rotate at the preset position.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] The existing motion mechanism that drives the air guide plate to extend and rotate is complex, and after long-term use, it is difficult to completely close the air guide plate with the air outlet, which affects the appearance. Summary of the Invention
[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0007] This disclosure provides a moving mechanism for an air guide plate in an air conditioner indoor unit and an air conditioner. By setting a stop, the air guide plate is completely closed with the air outlet, which improves the aesthetic performance of the air guide plate.
[0008] In some embodiments, the motion mechanism for the air guide plate of the air conditioner indoor unit includes: a crank with a rotating shaft; a driving connecting rod, one end of which is rotatably connected to the air guide plate, the driving connecting rod having a groove for sliding the rotating shaft, so that the driving connecting rod moves under the drive of the crank; and a driven connecting rod, one end of which is rotatably connected to the air guide plate, the driven connecting rod moving under the drive of the driving connecting rod, the driving connecting rod and the driven connecting rod driving the air guide plate to extend and close the air outlet of the air conditioner indoor unit, wherein the groove has a stop portion, and when the air guide plate is in the closed air outlet state, the rotating shaft of the crank abuts against the stop portion.
[0009] Optionally, the slide groove includes: a first edge portion near the edge of the active connecting rod; and a second edge portion near the middle of the active connecting rod, wherein the second edge portion is the stop portion.
[0010] Optionally, the length of the part of the active connecting rod where the slide groove is located is a first length, and the length of the slide groove is less than or equal to 1 / 2 of the first length; or, the distance between the rotation center of the crank and the rotation axis is a first distance, and the length of the slide groove is equal to the first distance, or greater than the first distance and less than twice the first distance.
[0011] Optionally, the groove is linear.
[0012] Optionally, the groove includes: an upper arc-shaped segment and a lower arc-shaped segment that are bent and connected, wherein the lower arc-shaped segment is disposed at the lower part of the corresponding position of the upper arc-shaped segment.
[0013] Optionally, the upper arc segment includes: a connecting end, which bends and connects with the lower arc segment; and a closed end, which is the other end opposite to the connecting end, and the closed end is the stop portion.
[0014] Optionally, the motion mechanism further includes: a track plate with a herringbone-shaped track, the herringbone-shaped track including a straight section and an upper branch section and a lower branch section branching from the straight section; the active linkage is provided with a first limiting slider that slides along the herringbone-shaped track, wherein the first limiting slider slides along the upper branch section to open the air guide plate downward; the first limiting slider slides along the lower branch section to open the air guide plate upward.
[0015] Optionally, the track plate further includes a straight track disposed at the lower part of the herringbone track; the active connecting rod further includes a second limiting slider that slides along the straight track, wherein the first limiting slider, the second limiting slider and the stop portion are collinear.
[0016] Optionally, the driven link is provided with a third limiting slider that slides along the linear track.
[0017] In some embodiments, the air conditioner includes the aforementioned motion mechanism for the air guide vane of the indoor unit.
[0018] The moving mechanism for the air guide plate of the indoor unit of an air conditioner and the air conditioner provided in this disclosure can achieve the following technical effects:
[0019] The motion mechanism for the air guide plate of an air conditioner indoor unit provided in this embodiment includes a crank, a driving connecting rod, and a driven connecting rod. The crank has a rotating shaft. One end of the driving connecting rod is rotatably connected to the air guide plate, and the driving connecting rod has a sliding groove for the rotating shaft to slide, so that the driving connecting rod moves under the drive of the crank. One end of the driven connecting rod is rotatably connected to the air guide plate, and the driving and driven connecting rods drive the air guide plate to extend and close the air outlet of the air conditioner indoor unit. The sliding groove has a stop portion, and when the air guide plate is in the closed outlet air state, the rotating shaft of the crank abuts against the stop portion.
[0020] In a motion mechanism without a stop in the slide, the program specifies the number of steps the stepper motor must take, such as 100 pulses, during the opening and closing process of the air guide plate. Theoretically, 95 pulses are required, with the extra 5 pulses used for overstepping to ensure the air guide plate fully opens. Overstepping can be understood as forcing the motor to rotate. After executing the theoretical pulse count minus 95 pulses during the opening and closing process, the air guide plate is considered to have accurately returned to its position. Over time, wear on the stepper motor shaft and the mounting holes of the corresponding crank increases the clearance, leading to a larger error between the actual rotation angle of the motor and the theoretical angle determined by the program. This, in turn, widens the closing gap of the air guide plate, affecting its appearance. Therefore, when programming the air guide plate motion mechanism, the wear between the motor shaft and the crank mounting holes must be taken into account to ensure that the crank's rotation axis is always in its initial position. This can also be described as aligning the crank's rotation axis, ensuring it is at an accurate starting point, guaranteeing the complete closure of the air outlet by the air guide plate, and ensuring the accuracy of the air guide plate's next opening angle. However, the variable amount of wear increases the difficulty of setting a program to ensure the crankshaft is aligned.
[0021] In the motion mechanism provided in this embodiment, the slide is provided with a stop. When the air guide plate is closed, only some simple stepping programs need to be added, such as setting 5-20 pulses. Due to the stopping effect of the stop, the movement of the rotating shaft caused by the excess pulses in the stepping program is stopped, realizing the automatic centering of the rotating shaft, thereby making the air guide plate and the air outlet completely closed.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0051] This disclosure provides an air conditioner.
[0052] This air conditioner is a large guide plate type. When the air guide plate 50 is closed, it can completely seal the air outlet, and there is no gap between the air guide plate 50 and the air outlet. Furthermore, during airflow, the air guide plate 50 extends out of the air conditioner before rotating to guide the air. This distance between the air guide plate 50 and the air outlet reduces air resistance, thus minimizing noise generated at the air guide plate 50 during airflow. Simultaneously, compared to rotating the air guide plate 50 at the air outlet, rotating it outside the air outlet allows for a wider angle and greater range of airflow, improving the cooling or heating effect of the air conditioner. Optionally, the air conditioner provided in this embodiment can also be a cabinet unit or a ducted unit, etc.
[0053] In some embodiments, the air conditioner includes the aforementioned motion mechanism for extending and rotating the air guide plate.
[0054] Optionally, motion mechanisms are provided on both sides of the air guide plate 50, and the motion mechanisms on both sides simultaneously drive the air guide plate 50 to move. The motion mechanisms described below can drive the air guide plate 50 to first extend out of the air outlet to a first preset position, and then drive the air guide plate 50 to rotate at a constant speed. The structure and motion process of the motion mechanisms are described in detail below.
[0055] This disclosure also provides a motion mechanism for driving the air guide plate 50 to extend and rotate, such as... Figures 1 to 13 As shown.
[0056] The motion mechanism for the air guide plate 50 of the indoor unit of an air conditioner provided in this embodiment includes a crank 10, a driving connecting rod 20, and a driven connecting rod 30. The crank 10 is provided with a rotating shaft 11. One end of the driving connecting rod 20 is rotatably connected to the air guide plate 50. The driving connecting rod 20 is provided with a sliding groove 21 for sliding on the rotating shaft 11, so that the driving connecting rod 20 moves under the drive of the crank 10. One end of the driven connecting rod 30 is rotatably connected to the air guide plate 50, and the driven connecting rod 30 moves under the drive of the driving connecting rod 20. The driving connecting rod 20 and the driven connecting rod 30 cause the air guide plate 50 to extend and close the air outlet of the indoor unit of the air conditioner.
[0057] The motion mechanism provided in this embodiment includes a crank 10, a driving connecting rod 20, and a driven connecting rod 30. The crank 10 can rotate under the drive of a stepper motor. The rotation shaft 11 of the crank 10 slides along the groove 21 of the driving connecting rod 20, thereby driving the driving connecting rod 20 to move. The driving connecting rod 20 then drives the driven connecting rod 30 to move. The motion mechanism provided in this embodiment can simultaneously drive the air guide plate 50 to extend and rotate, simplifying the structure of the air guide plate 50 motion mechanism.
[0058] Optionally, the slide 21 is provided with a stop 211, which abuts against the crank 10's rotating shaft 11 when the air guide plate 50 is in the closed outlet air state.
[0059] The sliding groove 212 on the active linkage without an abutment part is as follows Figure 6 As shown. In containing, as Figure 6 In the illustrated motion mechanism, when the air guide plate 50 closes the air outlet, the rotation shaft 11 of the crank 10 needs to be aligned to ensure that the air guide plate 50 is in the accurate starting position when it opens again. This alignment position can be understood as the middle position of the groove 212 without the abutment part. With increased use, friction creates a gap between the motor shaft and the mounting shaft of the crank 10, thus increasing the difficulty of aligning the rotation shaft 11 of the crank 10 when the air guide plate 50 closes the air outlet.
[0060] In the motion mechanism provided in this embodiment, the slide 21 is provided with a stop 211. The stop 211 allows for simple program control, ensuring that the rotation shaft 11 of the crank 10 is aligned when the air outlet of the air guide plate 50 is closed. This allows the air guide plate 50 to completely close the air outlet, improving the overall aesthetics of the indoor air conditioning unit and also enhancing the accuracy of the next opening angle of the air guide plate 50. Optionally, the stop 211 can be understood as a structure higher than the bottom of the slide 21. The stop 211 can be an external structural component of the slide 21, or it can be understood as an edge of the slide 21 that prevents the rotation shaft 11 of the crank 10 from continuing to slide.
[0061] Optionally, the slide 21 includes a first edge portion and a second edge portion. The first edge portion is close to the edge of the drive link 20, the second edge portion is close to the middle of the drive link 20, and the second edge portion is a stop portion 211.
[0062] The portion of the active connecting rod 20 containing the slide groove 21 includes an edge portion near one edge and a central portion near the middle. The two edges of the slide groove 21 serve as stop edges to prevent the rotating shaft 11 of the crank 10 from sliding further. Specifically, the stop portion 211 is located on the edge of the slide groove 21 near the middle of the active connecting rod 20. Here, "near the middle of the active connecting rod 20" can be understood as being closer to the middle of the active connecting rod 20 than the edge near the edge; it can also be understood as the second edge of the slide groove 21 being located in the middle of the active connecting rod 20 containing the slide groove 21. Figure 3 and Figure 4 As shown.
[0063] Optionally, the length of the part of the active link 20 where the slide groove 21 is located is a first length, and the length of the slide groove 21 is less than or equal to 1 / 2 of the first length.
[0064] Compared to Figure 6 The length of the slide groove 21 shown is approximately equal to the first length of the portion of the active link 20 in which it is located. In the motion mechanism provided in this embodiment, the length of the slide groove 21 is less than or equal to half of the first length, such as... Figure 3 and Figure 4 As shown. In this way, the second edge of the slide groove 21 can accurately play a stopping role, which is beneficial for the automatic centering of the rotating shaft 11 of the crank 10 when the air guide plate 50 is closed.
[0065] Optionally, the distance between the rotation center 112 of the crank 10 and the rotation shaft 11 is a first distance, and the length of the slide groove 21 is equal to the first distance, or the length of the slide groove 21 is greater than the first distance and less than twice the first distance.
[0066] like Figure 6 The slide groove 212 shown has a length approximately equal to the first length of the active link 20, without a stop. Figure 6 The length of the slide 212 shown is approximately twice the length of the first distance. According to... Figure 6 In the indicated orientation, the rotating shaft 11 of the crank 10 slides along the lower right half of the slide groove 212, causing the air guide plate 50 to open upward; when the motor reverses, the rotating shaft 11 of the crank 10 slides along the upper left half of the slide groove 212, causing the air guide plate 50 to open downward.
[0067] and Figure 6 Unlike the slide groove 212 without a stop shown, the slide provided in this embodiment is a semi-slide, such as... Figure 3 and Figure 4As shown. In the motion mechanism provided in this embodiment, whether the air guide plate 50 opens upwards or downwards, the rotation shaft 11 of the crank 10 slides along the slide groove 21 provided in this embodiment. The length of the slide groove 21 is equal to a first distance, or greater than the first distance but less than twice the first distance. Further, with the stop portion 211 of the slide groove 21, the second edge of the slide groove 21 can accurately play a stopping role, which is beneficial for the rotation shaft 11 of the crank 10 to automatically center when the air guide plate 50 is closed.
[0068] Optionally, the groove 21 is a straight line.
[0069] Straight groove 21 Figure 3 As shown, the second edge of the slide groove 21 located in the middle of the active connecting rod 20 is the stop part 211.
[0070] Optionally, the chute includes a bent and connected upper arc-shaped segment 22 and a lower arc-shaped segment 23, with the lower arc-shaped segment 23 located below the corresponding position of the upper arc-shaped segment 22.
[0071] The curved groove includes an upper arc-shaped section 22 and a lower arc-shaped section 23, such as... Figure 4 As shown. When the chute 21 is straight, the extension speed of the guide vane 50 is as follows: Figure 12 As shown. It can be seen that when the chute 21 is straight, the uniformity of the air guide plate 50 during the entire extension process is poor. The chute provided in this embodiment is curved. When the chute is curved, the extension speed of the air guide plate 50 is as follows: Figure 13 As shown, it can be seen that, compared to a straight chute, the entire extension process of the guide vane 50 approaches a uniform speed when the chute is curved. The curved chute provided in this embodiment improves the uniformity of the entire extension process of the guide vane 50.
[0072] Optionally, the upper arc segment 22 includes a connecting end and a closed end. The connecting end is one end that bends and connects with the lower arc segment 23, and the closed end is the other end opposite to the connecting end. The closed end is a stop portion 211.
[0073] like Figure 4 As shown, the closed end of the upper arc-shaped section 22 of the slide is the stop 211. This facilitates the automatic centering of the crank 10's rotation shaft 11 when the air guide plate 50 is closed. Optionally, the closed end of the upper arc-shaped section 22 is located at the middle of the drive connecting rod 20.
[0074] Optionally, the motion mechanism also includes a track plate 40. The track plate 40 is provided with a herringbone track, which includes a straight section and an upper branch section 41 and a lower branch section 42 branching off from the straight section. The active linkage 20 is provided with a first limiting slider 24 that slides along the herringbone track. The first limiting slider 24 slides along the upper branch section 41 to open the air guide plate 50 downward; the first limiting slider 24 slides along the lower branch section 42 to open the air guide plate 50 upward.
[0075] The track plate 40 is provided with a track capable of limiting the movement of the driving link 20 and the driven link 30. The track includes a herringbone track that limits the movement of the driving link 20, such as... Figure 8 As shown. The herringbone track includes a straight section extending along the extension direction of the air guide plate 50, as well as an upper branch section 41 and a lower branch section 42. Driven by the rotation shaft 11 of the crank 10, when the first limiting slider 24 of the active connecting rod 20 slides along the straight section, the air guide plate 50 extends to a first preset position. When the first limiting slider 24 slides along the upper branch section 41, the air guide plate 50 extends and rotates at the first preset position, causing the air guide plate 50 to open downwards. When the first limiting slider 24 slides along the lower branch section 42, the air guide plate 50 extends and rotates at the first preset position, causing the air guide plate 50 to open upwards.
[0076] Optionally, the track plate 40 further includes a straight track 43 disposed below the herringbone track. The active linkage 20 also includes a second limiting slider 25 that slides along the straight track 43. The first limiting slider 24, the second limiting slider 25, and the stop portion 211 are collinear.
[0077] like Figure 5 As shown, the active connecting rod 20 is also provided with a second limiting slider 25. The first limiting slider 24 and the second limiting slider 25 together limit the movement of the active connecting rod 20. The first limiting slider 24, the second limiting slider 25 and the stop part 211 are collinear, which can be understood as the stop part 211 of the slide groove 21 being set on the virtual straight line formed by the first limiting slider 24 and the second limiting slider 25. In this way, it is beneficial for the rotation shaft 11 of the crank 10 to automatically align when the air guide plate 50 is closed, thereby improving the closing effect of the air guide plate 50.
[0078] Optionally, the driven link 30 is provided with a through slide rail that passes through the driven link 30, and the second limiting slider 25 of the driving link 20 can pass through the through slide rail and slide along the straight track 43 of the track plate 40.
[0079] Optionally, the driven link 30 is provided with a third limiting slider that slides along the linear track 43.
[0080] There can be multiple third limit sliders, and these multiple third limit sliders are not on the same straight line. For example, there can be 3 third limit sliders, such as... Figure 7As shown, it includes third limiting sliders 1'31, 2'32, and 3'33. Correspondingly, the track plate 40 is provided with three straight tracks extending along the extension direction of the guide plate 50. The three third limiting sliders slide along the three straight tracks on the track plate 40, thus more stably limiting the linear motion of the driven link 30. Optionally, the three third limiting sliders are arranged in a triangle. This improves the limiting effect of the track plate 40 on the motion trajectory of the driven link 30.
[0081] Optionally, the motion mechanism also includes an electromagnetic element 44. The active linkage 20 is provided with an attraction element that can be attracted by the electromagnetic element 44. The electromagnetic element 44 is used to attract the attraction element when energized, causing the limiting portion of the active linkage 20 to slide along the upper branch 41 of the herringbone track, and the air guide plate 50 to open downward. Optionally, the electromagnetic element 44 is also used to allow the limiting portion of the active linkage 20 to slide along the lower branch 42 of the herringbone track when de-energized, and the air guide plate 50 to open upward.
[0082] Optionally, the "limiting part of the active link 20" can be understood as the aforementioned first limiting slider 24. When the first limiting slider 24 of the active link 20 moves along the linear track to the intersection of the upper branch section 41 and the lower branch section 42 of the track, under the gravity of the air guide plate 50, the first limiting slider 24 easily slides along the lower branch section 42 of the herringbone track, causing the air guide plate 50 to open upward. The motion mechanism provided in this embodiment also includes an electromagnetic element 44, and the active link 20 is provided with an attraction element that can be attracted by the electromagnetic element 44. When the electromagnetic element 44 is energized, the electromagnetic element 44 attracts the attraction element, overcoming the gravity of the air guide plate 50, causing the first limiting slider 24 to slide along the upper branch section 41, thereby causing the air guide plate 50 to open downward.
[0083] Optionally, the electromagnetic element 44 is disposed at the intersection of the upper branch section 41 and the lower branch section 42 of the herringbone track, and is located on the side closer to the upper branch section 41.
[0084] like Figure 8 As shown, the electromagnetic element 44 is positioned at the intersection of the herringbone track and close to the upper branch section 41. This allows the electromagnetic element 44 to attract the active connecting rod 20 to the upper branch section 41, causing the first limiting slider 24 of the active connecting rod 20 to slide along the upper branch section 41 of the herringbone track.
[0085] Optionally, the limiting part of the active link 20 includes a first limiting slider 24, and the attracting element is part or all of the first limiting slider 24.
[0086] A portion of the first limiting slider 24 serves as an attraction element. Optionally, the first limiting slider 24 is cylindrical, with the portion of the cylinder near the upper branch segment 41 serving as the attraction element. This facilitates the attraction of the electromagnetic element 44 to the first limiting slider 24.
[0087] Optionally, the track slab 40 includes a first surface and a second surface. The first surface is provided with a herringbone track, and the second surface is opposite to the first surface. The electromagnetic element 44 is disposed on either the first surface or the second surface.
[0088] Optionally, the electromagnetic element 44 can be disposed on the first plate surface, which is the same as the plate surface where the herringbone track is located. This is beneficial to improving the attraction effect of the electromagnetic element 44 on the attraction element. Optionally, the electromagnetic element 44 can be disposed on the second plate surface. This allows the electromagnetic element 44 to avoid the movement of the active connecting rod 20, which is beneficial to the sliding of the active connecting rod 20 along the herringbone track on the track plate 40. Optionally, the electromagnetic element 44 can also be embedded inside the track plate 40.
[0089] Optionally, the electromagnetic element 44 includes an electromagnet. The first limiting slider 24 includes an iron sliding core, which is an attraction element.
[0090] When the electromagnet is energized, it attracts the iron core in the first limiting slider 24, causing the first limiting slider 24 of the active connecting rod 20 to slide along the upper branch section 41 of the herringbone track, thereby opening the air guide plate 50 downward.
[0091] Optionally, the first limiting slider 24 may also include a sliding sleeve fitted over the outside of the iron sliding core. The sliding sleeve facilitates the smooth sliding of the first limiting slider 24 along the herringbone track.
[0092] The motion mechanism for the air guide plate 50 of the air conditioner indoor unit provided in this embodiment drives the air guide plate 50 to move in the following way:
[0093] When the air guide plate 50 is closed, the rotation shaft 11 of the crank 10 abuts against the stop portion 211 of the slide groove 21, and the rotation shaft 11 of the crank 10 is in a centered position. When the rotation shaft 11 of the crank 10 slides along the slide groove 21, it drives the limiting portions of the driving connecting rod 20 and the driven connecting rod 30 to slide within the track of the track plate 40, thereby driving the driving connecting rod 20 and the driven connecting rod 30 to move. Among them, the driving connecting rod 20 moves linearly along the straight section of the herringbone track, and the driven connecting rod 30 moves linearly along the straight track of the track plate 40, thereby driving the air guide plate 50 to extend linearly to the first preset position. The first preset position can be understood as the position of the air guide plate 50 corresponding to the end of the straight section when the first limiting slider 24 of the driving connecting rod 20 moves.
[0094] When the air guide plate 50 reaches the first preset position, the electromagnetic component 44 is de-energized. Under the action of gravity, the first limiting slider 24 of the active connecting rod 20 slides along the lower branch section 42 of the herringbone track, and the third limiting slider of the driven connecting rod 30 continues to slide along the linear track, causing the driven connecting rod 30 to move linearly. At this time, the active connecting rod 20 and the driven connecting rod 30 generate relative motion, thereby driving the air guide plate 50 to open upwards. Figure 10 As shown.
[0095] When the air guide plate 50 reaches the first preset position, the electromagnetic element 44 is energized. Under the attraction of the electromagnetic element 44 and the attraction element on the active connecting rod 20, the gravity of the air guide plate 50 is overcome, and the first limiting slider 24 of the active connecting rod 20 slides along the upper branch section 41 of the herringbone track. The third limiting slider of the driven connecting rod 30 continues to slide along the straight track, causing the driven connecting rod 30 to move linearly. At this time, the active connecting rod 20 and the driven connecting rod 30 generate relative motion, thereby driving the air guide plate 50 to open downwards. Figure 11 As shown.
[0096] Whether the air guide plate 50 opens upwards or downwards, the stepper motor reverses and, with a simple stepping program, the rotating shaft 11 of the crank 10 abuts against the stop part 211 of the slide groove 21. The rotating shaft 11 is in a centered state, and the air guide plate 50 and the air outlet are completely closed, thus closing the air outlet.
