[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.
[0049] An embodiment of the present disclosure provides an air conditioner.
[0050] The air conditioner is a large-guide-plate air conditioner. When the air guide plate 50 of the air conditioner is in the closed state, the air outlet can be completely closed, and there is no gap between the air guide plate 50 and the air outlet. In addition, during the air supply process of the air conditioner, the air guide plate 50 is first extended from the air conditioner and then rotated to guide the air. In this way, the air guide plate 50 is far away from the air outlet, and the wind resistance of the air flow blown out of the air conditioner is small, which can reduce the noise generated at the air guide plate 50 during the air supply process. At the same time, compared with the air guide plate 50 rotating at the air outlet to supply air, the air guide plate 50 rotating outside the air outlet can supply air at a larger angle and a larger range, thereby improving the cooling or heating effect of the air conditioner. Optionally, the air conditioner provided in the embodiment of the present disclosure can also be a cabinet unit or a duct unit.
[0051] In some embodiments, the air conditioner includes the above-mentioned motion mechanism for driving the air guide plate to extend and rotate.
[0052] Optionally, motion mechanisms are provided on both sides of the air deflector 50 to simultaneously drive the air deflector 50. The motion mechanisms described below can first extend the air deflector 50 out of the air outlet to a first preset position and then rotate the air deflector 50 at a constant speed. The structure and motion of the motion mechanisms are described in detail below.
[0053] The embodiment of the present disclosure also provides a motion mechanism for driving the air guide plate 50 to extend and rotate, such as Figures 1 to 13 shown.
[0054] The present disclosure provides a motion mechanism for an air deflector 50 in an air conditioner indoor unit, comprising a crank 10, an active connecting rod 20, and a passive connecting rod 30. The crank 10 is provided with a rotating shaft 11. One end of the active connecting rod 20 is rotatably connected to the air deflector 50. The active connecting rod 20 is provided with a sliding groove 21 for sliding the rotating shaft 11, so that the active connecting rod 20 moves under the drive of the crank 10. One end of the passive connecting rod 30 is rotatably connected to the air deflector 50. The passive connecting rod 30 moves under the drive of the active connecting rod 20. The active connecting rod 20 and the passive connecting rod 30 drive the air deflector 50 to extend and close the air outlet of the air conditioner indoor unit.
[0055] The motion mechanism provided in the disclosed embodiment includes a crank 10, an active connecting rod 20, and a passive connecting rod 30. The crank 10 can be rotated by a stepper motor, and the rotation axis 11 of the crank 10 slides along the slide groove 21 of the active connecting rod 20, thereby driving the active connecting rod 20, which in turn drives the passive connecting rod 30. The motion mechanism provided in the disclosed embodiment can simultaneously drive the air deflector 50 to extend and rotate, simplifying the structure of the air deflector 50's motion mechanism.
[0056] Optionally, the slide groove 21 is provided with a stop portion 211 , and when the air guide plate 50 is in a state of closing the air outlet, the rotating shaft 11 of the crank 10 abuts against the stop portion 211 .
[0057] In the motion mechanism where the slideway is not provided with a stopper, such as Figure 6 As shown, the slide groove 212 is not provided with an abutment portion. In the process of the air guide plate from closing to opening, the program stipulates the number of rotation steps of the stepper motor, such as 100 pulses; while the theoretical number of pulses required is 95, and the extra 5 pulses are used for over-stepping to ensure that the air guide plate is fully opened. Among them, over-stepping can be understood as forcing the motor to rotate. In the process of the air guide plate from opening to closing, after executing the theoretical number of pulses - 95, it is considered that the air guide plate has been accurately returned to its position. The stepper motor shaft and the mounting hole of the crank that matches it have increased gaps after long-term wear, resulting in a larger error between the actual rotation angle of the motor and the theoretical angle determined by the program, and then the closing gap of the air guide plate is increased, affecting the appearance. Therefore, when programming the air deflector mechanism, the wear between the motor shaft and the crank's mounting hole needs to be taken into account to ensure that the crank's rotation axis is always in its initial position. This can also be described as centering the crank's rotation axis and aligning it to its precise starting point, ensuring that the air deflector fully closes the air outlet and that the air deflector's next opening angle is accurate. However, the variable wear increases the difficulty of programming the crank's rotation axis.
[0058] In the motion mechanism provided in the embodiment of the present disclosure, the slide 21 is provided with a stopper 211. When the air guide plate is closed, only some simple step-by-step procedures need to be added, such as setting 5-20 pulses. Due to the stopping effect of the stopper, the movement of the rotating shaft caused by the redundant pulses in the step-by-step procedure is stopped, thereby achieving automatic centering of the rotating shaft, and thus completely closing the air guide plate and the air outlet. It can be seen that in the motion mechanism provided in the embodiment of the present disclosure, the setting of the stopper 211 can be coordinated with simple program control, so that the rotating shaft 11 of the crank 10 can be in a centered state when the air guide plate 50 closes the air outlet, so that the air guide plate 50 can completely close the air outlet, thereby improving the overall aesthetics of the air conditioner indoor unit, and also improving the accuracy of the next opening angle of the air guide plate 50. Optionally, the stopper 211 can be understood as a structure that is higher than the bottom of the slide 21. The stop portion 211 may be an additional structural component of the slide groove 21 , and may also be understood as an edge of the slide groove 21 that can stop the rotating shaft 11 of the crank 10 from continuing to slide.
[0059] Optionally, the sliding groove 21 includes a first edge portion and a second edge portion, wherein the first edge portion is close to the edge of the active connecting rod 20 , and the second edge portion is close to the middle portion of the active connecting rod 20 , and the second edge portion serves as a stop portion 211 .
[0060] The portion of the active connecting rod 20 where the chute 21 is located includes an edge portion close to one edge and a middle portion close to the middle. The two edges of the chute 21 are stop edges that prevent the rotating shaft 11 of the crank 10 from continuing to slide. Among them, the stop portion 211 is provided at the edge of the chute 21 close to the middle of the active connecting rod 20. The "close to the middle of the active connecting rod 20" here can be understood as being closer to the middle of the active connecting rod 20 than the edge close to the active connecting rod 20, and can also be understood as the second edge of the chute 21 being in the middle of the active connecting rod 20 where the chute 21 is located. As Figure 3 and Figure 4 shown.
[0061] Optionally, the length of the portion of the active connecting rod 20 where the sliding groove 21 is located is a first length, and the length of the sliding groove 21 is less than or equal to 1 / 2 of the first length.
[0062] Relative to Figure 6 The length of the chute 21 shown is substantially equal to the first length of the portion of the active link 20 where it is located. In the motion mechanism provided by the embodiment of the present disclosure, the length of the chute 21 is less than or equal to 1 / 2 of the first length, such as Figure 3 and Figure 4 In this way, the second edge of the chute 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.
[0063] Optionally, the distance between the rotation center 112 of the crank 10 and the rotation axis 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.
[0064] like Figure 6 The length of the sliding groove 212 without a stop portion is substantially equal to the first length of the active connecting rod 20, Figure 6 The length of the chute 212 shown is approximately equal to twice the first distance. Figure 6 In the orientation shown, the rotating shaft 11 of the crank 10 slides along the half-slide on the lower right side of the slide groove 212, driving the air guide plate 50 to open upward; the motor is reversed, and the rotating shaft 11 of the crank 10 slides along the half-slide on the upper left side of the slide groove 212, driving the air guide plate 50 to open downward.
[0065] and Figure 6 Unlike the slide 212 shown in FIG. 2 , which is not provided with a stopper, the slide provided in the embodiment of the present disclosure is a semi-slide. Figure 3 and Figure 4As shown. In the motion mechanism provided by the disclosed embodiment, whether the air deflector 50 is opened upward or downward, the rotating shaft 11 of the crank 10 slides along the slide 21 provided by the disclosed embodiment. The length of the slide 21 is equal to the first distance, or greater than the first distance and less than twice the first distance. Furthermore, the stop portion 211 of the slide 21 can ensure that the second edge of the slide 21 can accurately perform a stopping function, facilitating automatic centering of the rotating shaft 11 of the crank 10 when the air deflector 50 is closed.
[0066] Optionally, the slide groove 21 is linear.
[0067] The linear chute 21 is as follows Figure 3 As shown, the second edge of the sliding groove 21 located in the middle of the active connecting rod 20 is the stop portion 211 .
[0068] Optionally, the chute includes an upper arc segment 22 and a lower arc segment 23 that are connected by bending, and the lower arc segment 23 is arranged at the lower part of the corresponding position of the upper arc segment 22.
[0069] The curved chute includes an upper arc section 22 and a lower arc section 23. Figure 4 When the chute 21 is linear, the extension speed of the air guide plate 50 is as follows: Figure 12 As shown. It can be seen that when the chute 21 is linear, the uniformity of the speed of the air guide plate 50 during the entire extension process is poor. The chute provided in the embodiment of the present disclosure is curved. When the chute is curved, the extension speed of the air guide plate 50 is as follows: Figure 13 As shown in FIG. 1 , it can be seen that, compared with a linear chute, when the chute is curved, the entire extension process of the air deflector 50 approaches a uniform speed. The curved chute provided in the embodiment of the present disclosure improves the uniformity of the entire extension process of the air deflector 50.
[0070] Optionally, the upper arc segment 22 includes a connecting end and a closing end. The connecting end is one end connected to the lower arc segment 23 by bending, and the closing end is the other end opposite to the connecting end, and the closing end is the stopper 211.
[0071] like Figure 4 As shown, the closed end of the upper arc section 22 of the chute is the stopper 211. This is conducive to the automatic centering of the rotating shaft 11 of the crank 10 when the air deflector 50 is closed. Optionally, the closed end of the upper arc section 22 is located in the middle of the active connecting rod 20.
[0072] Optionally, the motion mechanism further includes a track plate 40. The track plate 40 is provided with a herringbone track, which includes a straight segment and an upper branch segment 41 and a lower branch segment 42 branching from the straight segment. The active connecting rod 20 is provided with a first limit slider 24 that slides along the herringbone track. The first limit slider 24 slides along the upper branch segment 41 to open the air deflector 50 downward; the first limit slider 24 slides along the lower branch segment 42 to open the air deflector 50 upward.
[0073] The track plate 40 is provided with a track capable of limiting the movement of the active link 20 and the driven link 30. The track includes a herringbone track that limits the movement of the active link 20, such as Figure 8 As shown. The herringbone track includes a straight section extending along the direction in which the air deflector 50 extends, as well as an upper branch section 41 and a lower branch section 42. Driven by the rotating 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 deflector 50 extends to a first preset position. When the first limiting slider 24 slides along the upper branch section 41, the air deflector 50 extends and rotates at the first preset position, causing the air deflector 50 to open downward. When the first limiting slider 24 slides along the lower branch section 42, the air deflector 50 extends and rotates at the first preset position, causing the air deflector 50 to open upward.
[0074] Optionally, the track plate 40 further includes a linear track 43 provided at the lower portion of the herringbone track. The active connecting rod 20 further includes a second limiting slider 25 sliding along the linear track 43. The first limiting slider 24, the second limiting slider 25 and the stopper 211 are colinear.
[0075] 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 stopper 211 are colinear. It can be understood that the stopper 211 of the chute 21 is located on the virtual straight line formed by the first limiting slider 24 and the second limiting slider 25. This facilitates automatic centering of the rotating shaft 11 of the crank 10 when the air deflector 50 is closed, thereby improving the closing effect of the air deflector 50.
[0076] Optionally, the driven connecting rod 30 is provided with a through slideway passing through the driven connecting rod 30 , and the second limiting slider 25 of the active connecting rod 20 can pass through the through slideway and slide along the linear track 43 of the track plate 40 .
[0077] Optionally, the driven connecting rod 30 is provided with a third limiting sliding block sliding along the linear track 43 .
[0078] The number of the third limit sliders can be multiple, and the multiple third limit sliders are not on the same straight line. For example, if there are 3 third limit sliders, Figure 7As shown, the track plate 40 includes a third limiting slider 1'31, a third limiting slider 2'32, and a third limiting slider 3'33. Correspondingly, the track plate 40 is provided with three linear tracks extending along the direction in which the air deflector 50 extends. The three third limiting sliders slide along the three linear tracks on the track plate 40, respectively. This can more stably limit the linear motion of the driven connecting rod 30. Optionally, the three third limiting sliders are arranged in a triangular shape. This improves the track plate 40's ability to limit the motion trajectory of the driven connecting rod 30.
[0079] Optionally, the motion mechanism further includes an electromagnetic element 44. The active link 20 is provided with an attraction element that can be attracted by the electromagnetic element 44. When powered on, the electromagnetic element 44 attracts the attraction element, causing the stopper of the active link 20 to slide along the upper branch 41 of the herringbone track, thereby opening the air deflector 50 downward. Optionally, when powered off, the electromagnetic element 44 also causes the stopper of the active link 20 to slide along the lower branch 42 of the herringbone track, thereby opening the air deflector 50 upward.
[0080] Optionally, the "limiting portion of the active connecting rod 20" can be understood as the aforementioned first limiting slider 24. When the first limiting slider 24 of the active connecting rod 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 action of the gravity of the wind guide plate 50, the first limiting slider 24 is easy to slide along the lower branch section 42 of the herringbone track, so that the wind guide plate 50 opens upward. The motion mechanism provided by the embodiment of the present disclosure also includes an electromagnetic element 44, and the active connecting rod 20 is provided with an attraction element that can be attracted by the electromagnetic element 44. When the electromagnetic element 44 is in the energized state, the electromagnetic element 44 is attracted to the attraction element, overcomes the gravity of the wind guide plate 50, and causes the first limiting slider 24 to slide along the upper branch section 41, so that the wind guide plate 50 opens downward.
[0081] 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 close to one side of the upper branch section 41 .
[0082] like Figure 8 As shown, the electromagnetic element 44 is disposed at the intersection of the herringbone track and close to one side of the upper branch section 41. This facilitates the electromagnetic element 44 to attract the active connecting rod 20 toward the side of 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.
[0083] Optionally, the limiting portion of the active connecting rod 20 includes a first limiting slider 24 , and the attracting element is part or all of the first limiting slider 24 .
[0084] Part of the first limit slider 24 serves as the attraction element. Optionally, the first limit slider 24 is cylindrical, and the cylindrical portion close to the upper branch section 41 serves as the attraction element. This facilitates the attraction of the electromagnetic element 44 to the first limit slider 24.
[0085] Optionally, the track plate 40 includes a first plate surface and a second plate surface. The first plate surface is provided with a herringbone track, and the second plate surface is opposite to the first plate surface. The electromagnetic element 44 is provided on the first plate surface or the second plate surface.
[0086] Alternatively, the electromagnetic element 44 can be located on the same first plate surface as the herringbone track. This helps enhance the electromagnetic element 44's attraction to the attraction element. Alternatively, the electromagnetic element 44 can be located on the second plate surface. This way, the electromagnetic element 44 avoids the movement of the active connecting rod 20, facilitating the sliding of the active connecting rod 20 along the herringbone track on the track plate 40. Alternatively, the electromagnetic element 44 can be embedded within the track plate 40.
[0087] Optionally, the electromagnetic element 44 includes an electromagnet. The first limit slider 24 includes an iron sliding core, which is an attraction element.
[0088] When energized, the electromagnet attracts the iron sliding 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.
[0089] Optionally, the first limiting slider 24 further includes a sliding sleeve sleeved on the outside of the iron sliding core. The provision of the sliding sleeve is conducive to the first limiting slider 24 sliding smoothly along the herringbone track.
[0090] The motion mechanism for the air deflector 50 of the air conditioner indoor unit provided in the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:
[0091] When the air deflector 50 is in the closed state, the rotating shaft 11 of the crank 10 abuts the stopper 211 of the chute 21, and the rotating shaft 11 of the crank 10 is in the centered position. When the rotating shaft 11 of the crank 10 slides along the chute 21, it drives the limiting portions of the active connecting rod 20 and the driven connecting rod 30 to slide within the track of the track plate 40, thereby driving the active connecting rod 20 and the driven connecting rod 30 to move. The active connecting rod 20 moves linearly along the straight section of the herringbone track, and the driven connecting rod 30 moves linearly along the linear track of the track plate 40, thereby driving the air deflector 50 to extend linearly to the first preset position. The first preset position can be understood as the position of the air deflector 50 corresponding to when the first limiting slider 24 of the active connecting rod 20 moves to the end of the straight section.
[0092] When the air deflector 50 reaches the first preset position, the electromagnetic element 44 is in the power-off state. Under the action of gravity, the first limit slider 24 of the active link 20 slides along the lower branch section 42 of the herringbone track, and the third limit slider of the driven link 30 continues to slide along the linear track, causing the driven link 30 to move linearly. At this time, the active link 20 and the driven link 30 generate relative motion, thereby driving the air deflector 50 to open upward, as shown in FIG. Figure 10 shown.
[0093] When the air guide plate 50 reaches the first preset position, the electromagnetic element 44 is in the energized state. Under the attraction of the electromagnetic element 44 and the attraction element on the active link 20, the gravity of the air guide plate 50 is overcome, and the first limit slider 24 of the active link 20 slides along the upper branch section 41 of the herringbone track, and the third limit slider of the driven link 30 continues to slide along the linear track, causing the driven link 30 to move linearly. At this time, the active link 20 and the driven link 30 generate relative motion, thereby driving the air guide plate 50 to open downward, as shown in FIG. Figure 11 shown.
[0094] Regardless of whether the above-mentioned air guide plate 50 is opened upward or downward, the stepper motor reverses and cooperates with a simple step-by-step procedure. The rotating shaft 11 of the crank 10 abuts against the stop portion 211 of the slide groove 21, the rotating shaft 11 is in a centered state, and the air guide plate 50 is completely closed with the air outlet, thereby achieving the closure of the air outlet.
