Description

Technical Field

[0001] This invention relates to the field of air conditioner swing mechanism technology, and in particular to an air conditioner swing mechanism and a cabinet air conditioner. Background Technology

[0002] The LP cabinet air conditioner is an upgraded floor-standing cabinet air conditioner based on the original round cabinet air conditioner. It retains the original open air supply structure of the PJ cabinet air conditioner and achieves left and right air sweeping function through multiple vertically placed air guide plates.

[0003] To drive the air guide plates to swing left and right for left and right air sweeping, existing technical solutions all use a full crank-connecting rod mechanism. This means that a connecting rod connects the crank assemblies on the four air guide plates in series, and the end of the connecting rod is connected to the crank assembly of the motor. When the motor rotates, the connecting rod will indirectly drive the four air guide plates to swing. However, this mechanism has high requirements for design and actual precision. It requires that the center positions of the air guide plates and the motor cranks follow the law of concircle, and the cranks connected to the air guide plates and the cranks connected to the motor must strictly follow the parallelogram law in order to achieve the driving swing of the connecting rod. If there is even a slight error in the design or the actual product, it will lead to the problem of motion stagnation and jamming, and failure of driving the air sweeping. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an air sweeping mechanism for an air conditioner and a cabinet air conditioner, which aims to solve the problem of stable air sweeping at multiple angles of the air guide plate in the existing air conditioner.

Therefore, they should not be construed as limiting this invention.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1 to 8 As shown, the present invention provides an air-sweeping mechanism for an air conditioner, which includes multiple air guide plates 1 and a driving mechanism 3. The multiple air guide plates 1 are respectively disposed in the air outlet of the indoor unit of the air conditioner and can rotate simultaneously in a preset direction to perform multi-angle air sweeping. The driving mechanism 3 includes a driving motor 4 and a transmission mechanism. The driving motor 4 is connected to the transmission mechanism, and the transmission mechanism is also connected to the multiple air guide plates 1. The driving motor 4 can drive the multiple air guide plates 1 to rotate simultaneously through the transmission mechanism to achieve air sweeping. By adopting the above solution, by designing a single driving motor, multiple air guide plates can be rotated simultaneously through the transmission mechanism to achieve air sweeping, making the structure of the entire air sweeping mechanism relatively simple and easier to achieve stable multi-angle air sweeping.

[0031] Preferably, in combination with the above schemes, such as Figures 1 to 8 As shown, the air guide plate 1 is provided with an air guide plate gear 6, which can drive the air guide plate 1 to rotate while rotating; further, the transmission mechanism includes a rotating component and a transmission assembly, and the rotating component is provided with a rack 10. The rotating component meshes with the air guide plate gears 6 on multiple air guide plates 1 simultaneously through the rack 10, thereby driving each air guide plate gear 6 to rotate simultaneously; further, the transmission assembly is respectively connected to the drive motor 4 and the rotating component for transmission; this allows the drive motor 4 to drive the rotating component to rotate through the transmission assembly, and the rotating component to drive multiple air guide plates 1 to rotate simultaneously, simplifying the entire air sweeping mechanism.

[0032] Preferably, in combination with the above schemes, such as Figures 2 to 5 As shown, in this embodiment: the rotating component is a rotating disk 5, which has a fan-shaped structure. A rack 10 is disposed on the arc-shaped edge of the rotating disk 5, and a groove 9 is also provided on the end face of the rotating disk 5. The rotating disk 5 can rotate around the supporting shaft 13 at its center. Further, the transmission assembly includes a drive connecting rod 7, a round pin 15, and a crank 19. One end of the crank 19 is movably connected to the output shaft of the drive motor 4, and the other end of the crank 19 is connected to one end of the drive connecting rod 7. The other end of the drive connecting rod 7 is movably connected to the round pin 15, which can be slidably disposed in the groove 9. Specifically, the drive motor 4 can drive the crank 19 to rotate with one end as the center point, and drive the round pin 15 to reciprocate within the groove 9 through the drive connecting rod 7, thereby driving the rotating disk 5 to reciprocate within a preset angle range. In the above design, the drive motor 4 can drive the crank 19 to reciprocate at a preset angle or to perform circular motion with one end as the center point, which can drive the drive connecting rod 7 to reciprocate in the horizontal direction. Figure 2As shown, the slide groove 9 has a long strip structure and is arranged radially along the fan-shaped structure at the middle position of the included angle of the fan. Specifically, when the drive linkage 7 drives the round pin 15 to slide to the middle position of the slide groove 9, the rack 10 is located at the middle position of the arc edge of the rotating disk 5. At this time, the air guide plate 1 is parallel to the side wall of the air outlet, and the two adjacent air guide plates 1 are also parallel to each other. When the round pin 15 slides to the lower limit position of the slide groove 9, the rotating disk 5 rotates to the right and the air guide plate 1 rotates to the left. When the round pin 15 slides to the upper limit position of the slide groove 9, the rotating disk 5 rotates to the left and the air guide plate 1 rotates to the right.

[0033] Preferably, in combination with the above schemes, such as Figure 6 As shown, in this embodiment: the rotating component is a rotating disk 5, which has a fan-shaped structure and can rotate around the supporting shaft 13 at its center; further, a rack 10 is disposed on the arc-shaped edge of the rotating disk 5, and a transmission ring 16 is fixedly disposed on the other side of the rotating disk 5 at its center, the transmission ring 16 having a groove 9 formed therein; further, the transmission assembly includes a pin 15 and a disk 18, wherein the disk 18 is disposed on the output shaft of the drive motor 4; further, the pin 15 is fixedly disposed on the disk 18 and extends into the groove 9; with the above design, the drive motor 4 can drive the disk 18 to reciprocate within a preset angle, and cause the disk 18 to drive the circular... Pin 15 reciprocates within the slide groove 9, thereby driving the rotating disk 5 to reciprocate within a preset angle range. The slide groove 9 has a long strip structure, and the transmission ring 16 is located on the middle line of the sector angle of the rotating disk 5. Specifically, when the disk 18 drives the pin 15 to slide to the middle position of the slide groove 9, the rack 10 is located at the middle position of the arc edge of the rotating disk 5. At this time, the air guide plate 1 is parallel to the side wall of the air outlet, and the two adjacent air guide plates 1 are also parallel to each other. When the pin 15 slides clockwise to the lower limit position of the slide groove 9, the rotating disk 5 rotates to the left, and the air guide plate 1 rotates to the right. When the pin 15 slides counterclockwise to the lower limit position of the slide groove 9, the rotating disk 5 rotates to the right, and the air guide plate 1 rotates to the left.

[0034] Preferably, in combination with the above schemes, such as Figure 7As shown, in this embodiment: the rotating component is a rotating disk 5, which has a fan-shaped structure. The rotating disk 5 can rotate around its center support shaft 13. A round pin 15 is fixed on the end face of the rotating disk 5, which can drive the rotating disk 5 to rotate together. A rack 10 is provided on the arc-shaped edge of the rotating disk 5. Further, the transmission assembly includes a transmission ring 16 and a transmission gear 21. A groove 9 is formed in the transmission ring 16, and the transmission ring 16 is movably connected to the round pin 15 through the groove 9. A drive rod 20 is also provided on the transmission ring 16. One side of the drive rod 20 meshes with the transmission gear 21 through its rack. The drive motor 4 is connected to the transmission gear 21. The above scheme enables the drive motor 4 to drive the transmission gear. 21 reciprocates within a preset angle, causing the transmission gear 21 to drive the drive rod 20 to reciprocate, which in turn causes the round pin 15 to reciprocate within the slide groove 9, thereby driving the rotating disk 5 to reciprocate within the preset angle range; specifically, the slide groove 9 has a long strip structure, and the drive rod 20 drives the transmission ring 16 to move. When the round pin 15 slides to the middle position of the slide groove 9, the rack 10 is located at the middle position of the arc edge of the rotating disk 5. At this time, the air guide plate 1 is parallel to the side wall of the air outlet, and the two adjacent air guide plates 1 are also parallel to each other; when the round pin 15 slides to the lower limit position of the slide groove 9, the rotating disk 5 rotates to the left, and the air guide plate 1 rotates to the right; when the round pin 15 slides to the upper limit position of the slide groove 9, the rotating disk 5 rotates to the right, and the air guide plate 1 rotates to the left.

[0035] Preferably, in combination with the above schemes, such as Figure 8As shown, in this embodiment: the rotating components are a connecting rod 22 and an arc-shaped rod 23. One end of the connecting rod 22 is fixedly connected to the middle position of the arc-shaped rod 23, and the other end of the connecting rod 22 can rotate around the supporting shaft 13. The supporting shaft 13 is set on the T-shaped support seat 24, and the rack 10 is set on the arc-shaped side of the arc-shaped rod 23. The connecting rod 22 is provided with a groove 9, and the T-shaped support seat 24 is provided with a slide rail 25. Further, the transmission assembly includes a crank 19, a driving connecting rod 7, a slider 26, and a round pin 15. Further, the round pin 15 is set on the slider 26 and extends into the groove 9. Specifically, the drive motor 4 can drive the crank 19 to reciprocate within a preset angle, and cause the crank 19 to drive the slider 26 to reciprocate on the slide rail 25 through the driving connecting rod 7. The slider 26 moves, causing the round pin 15 to reciprocate within the slide groove 9, and causing the arc rod 23 to reciprocate within a preset angle range. Specifically, the slide groove 9 has a long strip structure and is set along the length direction of the connecting rod 22 (i.e., the radial direction of the arc side of the arc rod 23). Specifically, when the slider 26 drives the round pin 15 to slide to the middle position of the slide groove 9, the rack 10 is located at the middle position of the arc side of the rotating disk 5. At this time, the air guide plate 1 is parallel to the side wall of the air outlet, and the two adjacent air guide plates 1 are also parallel to each other. When the slider 26 drives the round pin 15 to slide to the lower limit position of the slide groove 9, the rotating disk 5 rotates to the left and the air guide plate 1 rotates to the right. When the slider 26 drives the round pin 15 to slide to the upper limit position of the slide groove 9, the rotating disk 5 rotates to the right and the air guide plate 1 rotates to the left.

[0036] By adopting the above four implementation schemes, the air guide plate is ultimately driven to swing left and right through a simple transmission mechanism, which can avoid the problems of motion stagnation and jamming, and failure of driving the air sweeping.

[0037] Preferably, in combination with the above schemes, such as Figures 1 to 8 As shown, the rack 10 is an arc-shaped rack, which slides on the arc-shaped edge of the rotating disk 5 or the arc-shaped rod 23. Limiting grooves 17 are respectively provided at both ends of the arc-shaped edge of the rotating disk 5 or the arc-shaped rod 23. Specifically, the rack 10 is sleeved on the arc-shaped edge of the rotating disk 5 or the arc-shaped rod 23. Specifically, as shown... Figure 5The rack 10 is fitted onto the arc-shaped edge of the rotating disk 5 and can reciprocate on the arc-shaped edge. Limiting grooves 17 are provided on the arc-shaped edges at both ends of the rack 10. Specifically, when the rack 10 touches the limiting groove 17, the rack 10 starts to drive the air guide plate gear 6 to rotate, thereby driving the air guide plate 1 to swing and sweep air. Specifically, when the rotating disk 5 swings to the left (right) and reaches the limited limit position, the rotating disk 5 will swing in a different direction. At this time, the rack 10 will not be affected by the limiting end of the rotating disk 5 for a short period of time. When the air guide plate 1 swings to the limit position in a certain direction, it will be briefly buffered. This provides a certain buffer margin for the inertial swing of the air guide plate 1, and at the same time, it will be fully swept at the limit position before swinging in a different direction. With the above design, the rack 10 can play a buffering role when driving the air guide plate gear 6, improving the stability of its cooperation with the air guide plate gear 6.

[0038] Preferably, in combination with the above schemes, such as Figures 1 to 8 As shown, the transmission mechanism includes a support plate 8, which has a fan-shaped structure. A support shaft 13 is fixedly located at the center of the support plate 8. A rotating sleeve 14 is provided at the center of the rotating disk 5, and the rotating disk 5 is rotatably mounted on the support shaft 13 via the rotating sleeve 14. Furthermore, the support plate 8 has an arc-shaped groove 12. The fan-shaped angle of the rotating disk 5 is smaller than that of the support plate 8. Furthermore, the rotating disk 5 is located on the upper surface of the support plate 8, and the support plate 8 provides support. The bottom of the rotating disk 5 is slidably mounted in the arc-shaped groove 12 via a protrusion. Specifically, during the rotation of the rotating disk 5, the protrusion slides simultaneously within the arc-shaped groove 12, making the entire rotation more stable.

[0039] Preferably, in combination with the above schemes, such as Figures 1 to 8 As shown, four air guide plates 1 are vertically arranged inside the air outlet and can reciprocate around the vertical axis to achieve left and right air guidance; further, an air outlet frame 2 is provided on the indoor unit of the air conditioner, and an air outlet is formed inside the air outlet frame 2; further, the top of the air guide plate 1 is rotatably set on the panel at the top of the air outlet frame 2 through a connecting rod 11, and the connecting rod 11 protrudes from the panel; further, the air guide plate gear 6 is provided at the end of the connecting rod 11 that protrudes from the panel.

[0040] Accordingly, in conjunction with the above solutions, the present invention also provides a cabinet-type air conditioner, including a swing mechanism, which is disposed on the indoor unit of the air conditioner; specifically, the swing mechanism is the air conditioner swing mechanism described above.

[0041] The solution provided by this invention uses a drive motor to simultaneously drive multiple air guide plates to swing, thereby performing air sweeping. A simple transmission mechanism drives the air guide plates to swing left and right, while avoiding problems such as motion stagnation, jamming, and air sweeping failure of the air guide plates in air conditioners.
