Description

Technical Field

[0001] This invention relates to the technical field of air conditioners, and more specifically, to an indoor unit of an air conditioner. Background Technology

[0002] In the prior art, the indoor unit of an air conditioner includes a middle frame and an air deflector. The middle frame is provided with an air outlet, and the air deflector is located in the middle frame. When the air conditioner is turned off, the air deflector covers the air outlet. When the air conditioner is turned on, the air deflector opens the air outlet to allow air to flow smoothly.

[0003] However, as people place increasing emphasis on quality of life, their demands for air conditioning comfort are also rising. Current air conditioning indoor units exhibit a relatively strong airflow impact, resulting in subpar airflow comfort and failing to meet people's requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioner indoor unit to solve the technical problem of poor air supply comfort in existing air conditioner indoor units.

[0005] The air conditioner indoor unit provided by the present invention includes a mounting frame, multiple air guide plates, and a driving assembly. The mounting frame is provided with an air outlet. The multiple air guide plates are movably disposed within the mounting frame. The driving assembly is disposed in the mounting frame and is capable of selectively driving one of the air guide plates to extend to the air outlet.

[0006] The air conditioner indoor unit provided by this invention can produce the following beneficial effects:

[0007] The air conditioner indoor unit provided by this invention is equipped with multiple air guide vanes. A driving component can drive these vanes to extend to the air outlet, thus appropriately blocking the airflow and reducing or diluting the impact of the airflow, thereby improving the airflow effect and comfort. When the air-facing surfaces of the multiple air guide vanes have different structures, the airflow effects of different vanes will vary. When a user selects a certain airflow mode, it indicates that they require the airflow effect corresponding to that mode. The driving component simply drives the air guide vane corresponding to the desired airflow effect to extend to the air outlet, expanding the adaptability of the air conditioner, making selection more flexible, and further improving the airflow comfort of the indoor unit.

[0008] Furthermore, the air conditioner is a wall-mounted air conditioner, and the mounting frame is a middle frame.

[0009] Furthermore, the drive assembly includes a drive motor and a plurality of drive gears coaxially fixed to the output shaft of the drive motor. Each drive gear has only continuous partial teeth, and the axial projections of the teeth of each drive gear do not overlap. The plurality of air guide plates are stacked, and each air guide plate has a rack at its end near the drive assembly. Each rack corresponds to each drive gear.

[0010] With this technical solution, one drive motor can drive different air guide vanes, reducing the number of drive motors, lowering space requirements, and making the internal structure of the air conditioner more compact. During operation, the drive motor rotates, and when the teeth of the corresponding drive gear mesh with the rack of the air guide vane, the air guide vane can slide out relative to the middle frame.

[0011] Furthermore, the rack is disposed on the upper surface of the air guide plate, and the output shaft of the drive motor and the gear shaft of the drive gear are both arranged laterally.

[0012] Furthermore, in the two adjacent air guide plates, the upper surface of the end of the lower air guide plate is provided with a limiting edge, which is used to prevent the upper air guide plate from moving laterally; the rack is provided on the upper surface of the limiting edge; the bottom wall of the middle frame is provided with a limiting rib, which is used to prevent the bottom air guide plate from moving laterally.

[0013] Under this technical solution, the setting of the limiting ribs and each limiting edge can block the lateral movement of the corresponding air guide plate, thereby effectively preventing the air guide plate from swaying laterally, so that the rack of each air guide plate can stably mesh with the teeth of the corresponding drive gear, thus ensuring the normal operation of the drive component and the air guide plate.

[0014] Furthermore, the rack is disposed on the side end face of the air guide plate, and the output shaft of the drive motor and the gear shaft of the drive gear are both disposed in a direction perpendicular to the extension direction of the rack.

[0015] Furthermore, the indoor unit of the air conditioner also includes multiple reset components, each of which is corresponding to one of the multiple air guide plates. One end of each reset component is fixed to the mounting frame, and the other end is fixed to the corresponding air guide plate. Under the action of the reset component, the air guide plate is located in the initial position or always has a tendency to move back to the initial position.

[0016] Under this technical solution, when a certain air guide plate needs to be retracted, the drive motor rotates, causing the rack of the air guide plate to disengage from the teeth of the corresponding drive gear, and the reset component can then reset the air guide plate.

[0017] Furthermore, the reset element is a rubber band, which is connected to both the mounting frame and the air guide plate, and the rubber band is always in a stretched state; or, the reset element is a spring, which is connected to both the mounting frame and the air guide plate, and the spring is always in a stretched state.

[0018] Furthermore, the bottom wall of the middle frame is provided with a support rib, which is used to support the rear end of the air guide plate located at the bottom layer;

[0019] And / or, the bottom wall of the middle frame is provided with a limiting frame, the limiting frame is provided with a limiting opening, and the front end of the uppermost air guide plate is located in the limiting opening when it is in the initial position; each air guide plate extends through the limiting opening to the air outlet or retracts into the middle frame.

[0020] Under this technical solution, the supporting ribs can effectively support and stabilize the rear end of the air guide plate, thereby effectively preventing the air guide plate from swaying up and down. In the initial position, the limiting frame limits the front end of the uppermost air guide plate. Since the air guide plates are stacked and adjacent air guide plates limit each other, the limiting frame can limit each air guide plate. When the air guide plate extends or retracts, it passes through the limiting opening, so the limiting frame also plays a certain guiding role for each air guide plate, allowing each air guide plate to extend or retract smoothly.

[0021] Furthermore, the air guide plate includes a first air guide plate, which has a plurality of air outlet micro-holes; and / or, the air guide plate includes a second air guide plate, which has a plurality of air outlet elongated holes; and / or, the air guide plate includes a third air guide plate, which is a non-perforated plate.

[0022] Under this technical solution, the first air guide plate has a small air outlet, so it is suitable for the windless mode; the second air guide plate has a large air outlet, so it is suitable for the high air volume mode; the third air guide plate has no holes, so it is suitable for use when the air conditioner is off, which can prevent debris from entering the air conditioner from the air outlet.

[0023] Furthermore, a guide block or guide wheel is provided at the end of the air guide plate away from the drive component, the mounting frame is provided with a guide groove, and the guide block or the guide wheel is disposed in the guide groove and can move along the guide groove.

[0024] In this technical solution, the guide groove limits and guides the air guide plate through guide blocks or guide wheels, thereby further preventing the air guide plate from moving left and right.

[0025] Furthermore, the drive assembly includes multiple drive motors, each of which drives one of the air guide plates to extend to the air outlet.

[0026] Under this technical solution, the driving of each air guide plate is more independent. If the drive motor of one air guide plate has a problem, it will not have a fundamental impact on the use of other air guide plates. Attached Figure Description

[0044] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0045] First, it should be noted that in the attached diagram, the arrow "L" points to the left and the arrow "R" points to the right.

[0046] This embodiment provides an indoor air conditioning unit, including a mounting frame, multiple air guide plates, and a drive assembly. The mounting frame is provided with an air outlet 110. The multiple air guide plates are movably disposed within the mounting frame. The drive assembly is disposed in the mounting frame and can selectively drive one of the air guide plates to extend to the air outlet 110.

[0047] The air conditioner indoor unit provided in this embodiment, such as Figures 1 to 4 As shown, the indoor unit of this air conditioner is equipped with multiple air guide vanes. The drive assembly can drive the air guide vanes to extend to the air outlet 110. Therefore, the air guide vanes can appropriately block the airflow, thereby reducing or diluting the impact of the airflow and improving the airflow effect and comfort. When the air-facing surfaces of the multiple air guide vanes have different structures, the airflow effect of different air guide vanes will be different. When a user selects a certain airflow mode, it means that they need the airflow effect corresponding to that airflow mode. The drive assembly can then drive the air guide vane corresponding to the desired airflow effect to extend to the air outlet 110, thus expanding the adaptability of the air conditioner, making the selection more flexible, and further improving the airflow comfort of the indoor unit.

[0048] Specifically, in this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the air conditioner is a wall-mounted air conditioner, and the mounting frame is the middle frame 100. However, in other embodiments of this application, the air conditioner can also be other types of air conditioners, such as floor-standing air conditioners, which can also be equipped with multiple air guides, and the driving component can drive one of them to make the required air guide extend to the air outlet 110, thereby improving the air outlet effect and enhancing the air outlet comfort.

[0049] Specifically, in this embodiment, as Figures 3 to 10 As shown, the air guide plate includes a first air guide plate 210, a second air guide plate 220, and a third air guide plate 230. The first air guide plate 210 has multiple micro-outlet holes 214, the second air guide plate 220 has multiple elongated outlet holes 223, and the third air guide plate 230 is a holeless plate. In this configuration, the air outlet holes of the first air guide plate 210 are small, so it is suitable for the windless mode; the air outlet holes of the second air guide plate 220 are large, so it is suitable for the high air volume mode; the third air guide plate 230 is holeless, so it is suitable for use when the air conditioner is off, which can prevent debris from entering the air conditioner from the air outlet 110.

[0050] It should be noted that although there are three air guide plates in this embodiment, there may be only two air guide plates in other embodiments of this application, such as only the first air guide plate 210 and the third air guide plate 230; or, there may be more than three air guide plates, such as four or five. By setting different air outlets on different air guide plates, more different air outlet effects can be obtained.

[0051] Specifically, in this embodiment, the first air guide plate 210, the second air guide plate 220, and the third air guide plate 230 are stacked sequentially from bottom to top. However, in other embodiments of this application, the order of the air guide plates is not limited to this. For example, the first air guide plate 210, the second air guide plate 220, and the third air guide plate 230 can also be stacked sequentially from top to bottom.

[0052] Specifically, in this embodiment, as Figure 5As shown, the drive assembly includes a drive motor 300 and multiple drive gears coaxially fixed to the output shaft of the drive motor 300. Each drive gear has only continuous partial teeth, and the axial projections of the teeth of each drive gear do not overlap. Multiple air guide plates are stacked, and each air guide plate has a rack near its end in the drive assembly. Each rack corresponds to a drive gear. More specifically, in this embodiment, there are three drive gears: a first gear 410, a second gear 420, and a third gear 430. These three drive gears correspond to the first air guide plate 210, the second air guide plate 220, and the third air guide plate 230. With this configuration, one drive motor 300 can drive different air guide plates, reducing the number of drive motors 300, reducing space occupation, and making the internal structure of the air conditioner more compact. During operation, the drive motor 300 rotates, and when the teeth of the corresponding drive gear mesh with the rack of the air guide plate, the air guide plate can slide out relative to the middle frame 100.

[0053] It should be noted that in other embodiments of this application, the drive assembly may also include multiple drive motors 300, each of which drives one of the air guide plates to extend to the air outlet 110. That is, one drive motor 300 drives one air guide plate, and of course, only one air guide plate extends to the air outlet 110 at a time. With this configuration, the driving of each air guide plate is more independent, and a problem with the drive motor of one air guide plate will not fundamentally affect the use of the other air guide plates.

[0054] Specifically, in this embodiment, as Figure 4 and Figure 5 As shown, a rack is disposed on the upper surface of the air guide plate, and the output shaft of the drive motor 300 and the gear shaft of the drive gear are both arranged in the transverse direction, i.e., left-right direction. However, in other embodiments of this application, the arrangement of the rack and drive assembly is not limited to this. For example, the rack can also be disposed on the side end face of the air guide plate, and the output shaft of the drive motor 300 and the gear shaft of the drive gear are both arranged in a direction perpendicular to the extension direction of the rack, which can also selectively drive each air guide plate.

[0055] Specifically, in this embodiment, as Figure 5As shown, in two adjacent air guide plates, a limiting edge is provided on the upper surface of the end of the lower air guide plate to prevent the upper air guide plate from moving laterally. A rack is provided on the upper surface of the limiting edge. A limiting rib 121 is provided on the bottom wall 120 of the middle frame 100 to prevent the bottom air guide plate from moving laterally. In this configuration, the limiting rib 121 and each limiting edge can prevent the corresponding air guide plate from moving laterally, thereby effectively preventing the air guide plate from swaying laterally. This allows the rack of each air guide plate to mesh stably with the teeth of the corresponding drive gear, thus ensuring the normal operation of the drive assembly and the air guide plate.

[0056] More specifically, in this embodiment, the first air guide plate 210 is provided with a first limiting edge 211, and a first rack 212 is provided on the upper surface of the first limiting edge 211. The first limiting edge 211 can prevent the second air guide plate 220 from moving laterally in the direction of the drive motor 300. The second air guide plate 220 is provided with a second limiting edge 221, and a second rack 222 is provided on the upper surface of the second limiting edge 221. The second limiting edge 221 can prevent the third air guide plate 230 from moving laterally in the direction of the drive motor 300. The limiting rib 121 provided on the bottom wall 120 of the middle frame 100 can prevent the first air guide plate 210 from moving laterally in the direction of the drive motor 300.

[0057] Specifically, in this embodiment, the indoor unit of the air conditioner also includes multiple reset components, each corresponding to a specific air guide plate. One end of each reset component is fixed to the mounting frame, and the other end is fixed to the corresponding air guide plate. Under the action of the reset component, the air guide plate is located in its initial position or always has a tendency to return to its initial position. In this configuration, when a certain air guide plate needs to retract, the drive motor 300 rotates, causing the rack of the air guide plate to disengage from the teeth of the corresponding drive gear, and the reset component can then reset the air guide plate.

[0058] More specifically, in this embodiment, the reset component includes a first reset component, a second reset component, and a third reset component. The first reset component is a first elastic band 510, used for resetting the first air guide plate 210; the second reset component is a second elastic band 520, used for resetting the second air guide plate 220; and the third reset component is a third elastic band 530, used for resetting the third air guide plate 230. Each elastic band is connected to the mounting frame and the air guide plate, and each elastic band is always in a stretched state.

[0059] It should be noted that in other embodiments of this application, the reset element is not limited to a rubber band. For example, the reset element can also be a spring, which is connected to both the mounting frame and the air guide plate, and the spring is always in a stretched state. When the air guide plate is disengaged from the corresponding drive gear, the spring can also reset the air guide plate.

[0060] Specifically, in this embodiment, as Figure 5As shown, the bottom wall 120 of the middle frame 100 is provided with an inner limiting plate 123 to prevent the guide plates from moving backward. Furthermore, the inner limiting plate 123 is provided with three fixed mounting positions 124, and each air guide plate has a movable mounting position 213 on its end face facing the drive motor 300. One end of the elastic band is positioned at the corresponding movable mounting position 213, and the other end is positioned at the corresponding fixed mounting position 124.

[0061] Specifically, in this embodiment, as Figure 4 As shown, the bottom wall 120 of the middle frame 100 is provided with a support rib 122, which is used to support the rear end of the bottom air guide plate. The air guide plate has an upward curved arc, which can effectively support and stabilize the rear end of the air guide plate, thereby effectively preventing the air guide plate from swaying up and down.

[0062] Specifically, in this embodiment, as Figure 2 and Figure 3 As shown, a limiting frame 130 is provided on the bottom wall 120 of the middle frame 100, and the limiting frame 130 is provided with a limiting opening 131. When the uppermost air guide plate is in its initial position, its front end is located within the limiting opening 131. Each air guide plate extends to the air outlet 110 or retracts into the middle frame 100 through the limiting opening 131. In this configuration, when in the initial position, the limiting frame 130 limits the front end of the uppermost air guide plate. Since the air guide plates are stacked, adjacent air guide plates also limit each other, so the limiting frame 130 can limit each air guide plate. When the air guide plate extends or retracts, it passes through the limiting opening 131, so the limiting frame 130 also provides a certain guiding function for each air guide plate, allowing each air guide plate to extend or retract smoothly.

[0063] Specifically, in this embodiment, a guide block (not shown) or guide wheel (not shown) is provided at the end of the air guide plate away from the drive assembly, and a guide groove (not shown) is provided on the mounting frame. The guide block or guide wheel is disposed in the guide groove and can move along the guide groove. In this configuration, the guide groove limits and guides the air guide plate through the guide block or guide wheel, thereby further preventing the air guide plate from moving left and right. Of course, a limiting plate can also be provided on the bottom wall 120 of the middle frame 100, which is opposite to the limiting rib 121, thereby preventing the end of the air guide plate away from the drive assembly from sliding left and right; or, the end of the air guide plate away from the drive assembly can be in direct contact with the components or structures inside the middle frame 100, thus preventing lateral movement.

[0064] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0065] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
