Description

Technical Field

[0001] This utility model relates to the field of air conditioner damper plate technology, and in particular to a moving structure for a household air conditioner damper plate and an air conditioner. Background Technology

[0002] In residential central air conditioning systems, the damper plate is a key component for opening and closing the air intake channel. It works in conjunction with the air intake panel to optimize air quality by adjusting the air intake volume. Its movement is driven by a motor and can achieve rotation or translation. However, in actual operation, due to various factors such as uneven mass distribution, insufficient motor control precision, and excessive friction, the damper plate may vibrate or jam during operation, resulting in significant noise.

[0003] Chinese Patent CN215909367U discloses a planar damper and a ceiling-mounted air purifier. The planar damper includes a door panel, a support unit, and a motor. The support unit has a door hole and a slide rail. The door panel is stacked parallel to the support unit and slidably connected to the slide rail. The door panel is equipped with a rack. The motor is mounted on the support unit, and one end of the motor's output shaft is connected to a gear. This achieves relatively smooth operation and low noise for the planar damper. However, the motor is fixedly mounted on the support unit, while the rack is integrally formed with the door panel. The door panel is moved by the rotation of the gear. The movement stroke is affected by the length of the rack. When the rack moves to its maximum or minimum stroke, the gear may only mesh with a few teeth at the end of the rack. When the gear transmits force to the door panel, different positions on the door panel experience different driving forces, which can easily cause vibration or tooth skipping, generating noise. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a moving structure for a household air conditioner damper panel. It solves the problem that in existing technologies, when the rack and pinion are integrated with the door panel, the meshing stiffness between the gear and the rack decreases when the gear at the motor output end drives the rack to move to its maximum or minimum stroke. This results in uneven force on the door panel, causing vibration or tooth skipping, which leads to increased noise.

[0005] According to an embodiment of the present invention, a moving structure for a household air conditioner damper includes an air inlet panel and a damper. The air inlet panel has an air inlet, and a rack is detachably provided on the side wall of the air inlet panel along its length. The side wall of the air inlet panel has a sliding groove for the damper to slide horizontally. A drive motor is provided on the damper, and a gear is fixedly provided on the output end of the drive motor. The gear meshes with the rack.

[0006] Compared with the prior art, this utility model has the following beneficial effects: By adopting a sliding connection between the damper plate and the side wall of the air inlet panel, when the drive motor on the air inlet panel is started, the gear at its output end rotates. Since the gear meshes with the rack set on the air inlet panel, the damper plate moves horizontally, thereby adjusting the size of the air inlet on the air inlet panel. Since the motor is set on the damper plate, when the damper plate moves horizontally under the driving force of the motor and the gear, the driving force on the damper plate at any position will not change significantly, making the movement of the damper plate more stable, reducing the vibration during the movement of the damper plate, thereby reducing noise and improving the user experience.

[0007] Furthermore, a T-shaped boss is formed on the side of the air inlet panel facing the damper plate. The T-shaped boss and the air inlet panel form a sliding groove for the damper plate to slide. A rack is set on the side wall of the air inlet panel and is set opposite to the T-shaped boss. A receiving plate is provided on the side of the rack facing the air inlet panel, and an L-shaped extension plate is provided on the side of the rack facing the T-shaped boss. The side of the damper plate away from the T-shaped boss is slidably connected to the receiving plate.

[0008] Furthermore, the rack and pinion are connected to the air intake panel by screws.

[0009] Furthermore, the rack has several mounting slots on the side facing the air inlet panel, and the air inlet panel has several connecting platforms that correspond one-to-one with the mounting slots on the side facing the rack. Each connecting platform has a connecting post, and each connecting post has a threaded hole for screw connection. The rack has several connecting holes that communicate with the mounting slots.

[0010] Furthermore, each connecting platform is concave.

[0011] Furthermore, each of the four corners of the damper panel is equipped with a mounting platform, and each mounting platform is equipped with a rotatable roller.

[0012] Furthermore, the sidewalls of the air vent plate are equipped with reinforcing ribs.

[0013] Furthermore, a limiting rib is provided on the side of the air inlet panel facing the damper plate.

[0014] Furthermore, several air guide strips are provided at the air inlet of the air inlet panel.

[0015] Furthermore, each air guide strip has symmetrically inclined slopes.

[0016] Furthermore, the bevels on each air guide are inclined at 45° relative to the horizontal plane.

[0017] This utility model also provides an air conditioner, including any of the above-mentioned household air conditioner damper plate moving structures. Attached Figure Description

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 3As shown in the figure, this utility model embodiment proposes a moving structure for a household air conditioner damper, including an air inlet panel 1 and a damper 3. The air inlet panel 1 has an air inlet, and a rack 2 is detachably provided on the side wall of the air inlet panel 1 along its length direction. The side wall of the air inlet panel 1 has a sliding groove for the damper 3 to slide horizontally. The damper 3 is provided with a drive motor 4, and a gear 5 is fixedly provided on the output end of the drive motor 4. The gear 5 meshes with the rack 2. In this embodiment, the drive motor 4 is fixedly installed in the middle of the damper plate 3 through a motor mounting box. The air conditioner is a central air conditioner. The air inlet on the air inlet panel 1 allows the air conditioner to draw in external air. When it is necessary to open or close the air inlet on the air inlet panel 1, the drive motor 4 is started. The drive motor 4 rotates, causing the gear 5 on its output end to rotate accordingly. Since the drive motor 4 is fixed on the damper plate 3 and the gear 5 meshes with the rack 2, the damper plate 3 will move along the length direction of the rack 2. Since the drive motor 4 is fixed on the damper plate 3, the driving force on any position of the damper plate 3 is always the same during the horizontal movement, and the force is uniform, so that the damper plate 3 moves more smoothly. The meshing process of the gear 5 and the rack 2 is also smoother, which significantly reduces the occurrence of vibration and noise.

[0029] like Figures 6 to 7 As shown, further, a T-shaped boss 6 is formed on the side of the air inlet panel 1 facing the damper plate 3. The T-shaped boss 6 and the air inlet panel 1 form a sliding groove for the damper plate 3 to slide. The rack 2 is set on the side wall of the air inlet panel 1 and is set opposite to the T-shaped boss 6. A receiving plate 7 is provided on the side of the rack 2 facing the air inlet panel 1. An L-shaped extension plate 8 is provided on the side of the rack 2 facing the T-shaped boss 6. The side of the damper plate 3 away from the T-shaped boss 6 is slidably connected to the receiving plate 7. In this embodiment, the T-shaped boss 6 is integrally formed with the air inlet panel 1, and the receiving plate 7 and the L-shaped extension plate 8 are integrally formed with the rack 2. In order to stabilize the sliding of the damper plate 3 and guide the sliding of the damper plate 3, one end of the damper plate 3 is engaged in the groove formed between the T-shaped boss 6 and the air inlet panel 1, and the other end of the damper plate 3 is engaged in another groove formed by the rack 2, the L-shaped extension plate 8, the receiving plate 7 and the air inlet panel 1. By setting the T-shaped boss 6, the extension plate 8 and the receiving plate 7, the two ends of the damper plate 3 are limited, so that when the damper plate 3 moves horizontally, its two ends are tightly limited by the T-shaped boss 6, the extension plate 8, the receiving plate 7 and the air inlet panel 1, so that it slides stably and is not prone to vibration, thereby reducing noise.

[0030] Furthermore, the rack 2 is connected to the air inlet panel 1 by screws. The rack 2 and the air inlet panel 1 are detachably connected by screws, which makes it easy to replace the rack 2 when the teeth of the rack 2 are damaged. It also makes it easy to replace the rack 2 with racks of different lengths as needed, thereby changing the stroke of the damper plate 3.

[0031] like Figure 3 and Figure 4 As shown, furthermore, the rack 2 has several mounting slots on the side facing the air inlet panel 1, and the air inlet panel 1 has several connecting platforms 9 corresponding to the mounting slots on the side facing the rack 2. Each connecting platform 9 has a connecting post 10, and each connecting post 10 has a threaded hole for screw connection. The rack 2 has several connecting holes communicating with the mounting slots. In this embodiment, there are three mounting slots and three connecting posts. When installing the rack 2, the connecting posts 10 on the connecting posts are aligned with the mounting slots, and then the screws are screwed through the mounting holes on the rack 2 and screwed into the connecting posts 10. The connecting posts 10 serve a positioning function, facilitating the production and assembly of this device. In this embodiment, because a locking position needs to be left for the damper plate 3 and for the gear 5 to mesh with the rack 2, the connecting platform 9 is not embedded in the mounting slot. In a preferred embodiment, the size of the mounting groove is the same as the size of the connecting platform 9. The connecting platform 9 can be inserted into the mounting groove to position the rack 2 and restrict the horizontal displacement of the rack 2, thus ensuring the stability of the rack 2 during use.

[0032] like Figure 3 and Figure 4 As shown, each connecting platform 9 is concave. Specifically, the cross-section of the connecting platform 9 is concave, and both wings of the connecting platform 9 are fixed to the air inlet panel 1. The connecting boss provides an installation position for the rack 2. In a preferred embodiment, the threaded hole of the connecting post 10 communicates with the groove of the connecting platform 9. This allows for the use of screws of different lengths to connect the rack 2 to the connecting post 10. When a longer screw passes through the connecting post 10, it will enter the groove of the connecting platform 9 without interference or obstruction.

[0033] like Figure 3 and Figure 5 As shown, furthermore, each of the four corners of the damper plate 3 is provided with a mounting platform 11, and each mounting platform 11 is rotatably equipped with a roller 12. When the damper plate 3 moves, the rollers 12 on the four corners of the damper plate 3 slide and abut against the side wall of the receiving plate 7 and the side wall of the T-shaped protrusion 6, respectively. By setting the rollers 12, the sliding friction when the damper plate 3 moves is changed into rolling friction, thereby making the damper plate 3 move more smoothly and reducing noise.

[0034] like Figures 1 to 3 As shown, furthermore, the side wall of the air vent plate is provided with reinforcing ribs 13. In this embodiment, the reinforcing ribs 13 are cross-shaped. Since the drive motor 4 is mounted on the damper plate 3, the reinforcing ribs 13 can improve the strength of the damper plate 3.

[0035] like Figures 1 to 3As shown, furthermore, a limiting rib 14 is provided on the side of the air inlet panel 1 facing the damper plate 3. The limiting rib 14 limits the movement of the damper plate 3. In this embodiment, the drive motor 4 is a stepper motor, and two types of limiting ribs 14 are provided on the air inlet panel 1: one extends into a strip along the width direction of the air inlet panel 1, and the other extends into a strip along the length direction of the air inlet panel 1. Three such limiting ribs 14 are provided.

[0036] like Figures 2 to 3 , Figure 8 As shown, furthermore, the air inlet panel 1 is provided with several air guide strips 15. The two ends of the air guide strips are connected to the inner wall of the air inlet, and the air guide strips are evenly spaced along the length of the air inlet. The air guide strips can prevent the user's hand from reaching into the air conditioner and play a blocking role.

[0037] like Figure 8 As shown, each air guide slat 15 is further provided with symmetrically inclined slopes 16. By providing inclined slopes 16 on the air guide slats 15, when air enters the air conditioner, the air guide slats 15 guide the airflow and guide the airflow smoothly into the air conditioner.

[0038] Furthermore, the inclined surface 16 on each air guide slab 15 is inclined at 45° relative to the horizontal plane. In this embodiment, the inclined surface 16 on the air guide slab 15 is inclined at 45°, resulting in a relatively small whistling sound when air is drawn in. In this embodiment, the inclined surface 16 of the air guide slab 15 is inclined downwards towards the lower left corner. As a similar embodiment, the inclined surface 16 of the air guide slab 15 can also be inclined at 45° towards the upper left corner.

[0039] This utility model also provides an air conditioner, including any of the above-mentioned household air conditioner damper plate moving structures. A connecting ear is provided on the air inlet panel 1, through which the household air conditioner damper plate 3 moving structure is connected to the air conditioner body. A drive motor 4 drives the damper plate 3 to adjust the size of the air inlet, allowing the air conditioner to obtain different amounts of air intake and optimize indoor air quality.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
