Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically providing an indoor air conditioning unit and an air conditioner. Background Technology

[0002] Traditional air conditioners typically focus on quickly regulating the temperature of localized areas within a room, resulting in a concentrated airflow pattern. This concentrated airflow can easily cause discomfort for people.

[0003] In related technologies, airflow optimization techniques mostly focus on improving passive airflow guiding structures. Typical static airflow guiding components use fixed grilles or unidirectional guide vanes to provide basic airflow dispersion. While this can alleviate direct airflow under specific conditions, its inherent limitations due to the rigidity of the mechanical structure make it difficult to dynamically respond to changes in environmental parameters and personalized user needs. When faced with different spatial layouts, temperature and humidity conditions, or usage scenarios, existing airflow guiding solutions reveal inherent defects such as a single adjustment dimension and a lack of adaptive capabilities. This structural contradiction between static adjustment mechanisms and dynamic comfort requirements leads to significant limitations in the airflow softening accuracy and scenario adaptability of traditional technical solutions.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] This application aims to solve the above-mentioned technical problems, namely, to solve the problem that the concentrated air supply of existing air conditioners causes discomfort to the human body, and that the airflow guiding structure is difficult to dynamically adapt to the environment and user needs due to its fixed mechanical structure, resulting in a single adjustment dimension and poor adaptability.

[0006] In a first aspect, this application provides an indoor air conditioning unit, comprising:

[0007] The casing has an air outlet on it;

[0008] An air guide plate is disposed at the air outlet. The air guide plate has a sandwich layer inside, and the surface of the air guide plate has through holes communicating with the sandwich layer.

[0009] A flow-disrupting component is disposed within the interlayer;

The turbulence component is connected to the transmission shaft, and the drive motor drives the transmission shaft to rotate by a predetermined angle to adjust the extension amount of the turbulence component.

[0012] Optionally, the drive shaft includes:

[0013] A first drive shaft is connected to the output end of the drive motor;

[0014] A second drive shaft is disposed close to the first drive shaft and is connected to the first drive shaft in a transmission manner, so that when the drive motor drives the first drive shaft to rotate, the second drive shaft rotates about its own axis.

[0015] Optionally, multiple aerodynamic components are provided, and the multiple aerodynamic components are respectively spaced apart along the axial direction of the first drive shaft and the second drive shaft.

[0016] Optionally, the aerodynamic component includes a first aerodynamic element, which is a telescopic sleeve.

[0017] Optionally, the telescopic sleeve includes:

[0018] A transmission rod, which is connected to the transmission shaft;

[0019] A sleeve is connected to the transmission rod. When the transmission shaft rotates, it can drive the transmission rod to rotate, thereby causing the sleeve to move axially along the transmission rod.

[0020] Optionally, the indoor unit of the air conditioner further includes a first gear and a second gear meshing with the first gear, wherein the first gear is disposed on the transmission shaft and the second gear is disposed on the transmission rod.

[0024] With the above technical solution adopted, the air conditioner indoor unit provided by this application can intelligently switch between two operating modes, namely extension and retraction, by controlling the turbulence component, thereby responding to the human body's thermal comfort needs in real time: in the retraction mode, the airflow channel is maximized to achieve rapid adjustment of indoor temperature; in the extension mode, the turbulence component intervenes to decompose the concentrated airflow into a multi-directional diffused gentle airflow, while improving the uniformity of temperature distribution in the space, which helps to eliminate the physical discomfort caused by direct airflow.

[0038] Please refer to Figure 1 An air conditioner indoor unit 1 according to an embodiment of this application is provided with an air outlet on its housing 11, and an air guide plate 12 is provided at the air outlet. The air guide plate 12 is pivotally mounted at the air outlet. An active air turbulence component 20 is provided on the air guide plate 12. The air turbulence component 20 can perform different levels of air turbulence operation on the airflow at the air outlet according to different usage scenarios and users' personalized needs.

[0039] Specifically, refer to Figure 2 This is a cross-sectional view of the air guide plate 12. A sandwich-type receiving cavity is formed within the air guide plate 12, and the turbulence-disrupting component 20 is disposed within this cavity. Furthermore, through holes 120 communicating with the receiving cavity are spaced apart on the surface of the air guide plate 12. When the drive assembly is activated, the turbulence-disrupting component 20 can extend or retract axially: in the extended state, the extended portion of the turbulence-disrupting component 20 physically blocks the concentrated airflow at the air outlet, cutting it into multiple discrete airflow streams. Simultaneously, the surface of the extended portion of the turbulence-disrupting component 20 disrupts the originally smooth airflow, causing the airflow to generate irregular rotation and dispersion motion, thereby achieving a turbulence effect on the airflow; in the retracted state, the turbulence-disrupting component 20 is completely hidden within the sandwich layer, at which point the airflow can be smoothly output along the surface of the air guide plate 12.

[0040] The indoor air conditioning unit 1 provided in this embodiment can respond to the human body's thermal comfort needs in real time by intelligently switching between two operating modes: in the retracted mode, the airflow channel is maximized to achieve rapid adjustment of indoor temperature; in the extended mode, the baffle component 20 intervenes to decompose the concentrated airflow into a multi-directional diffused gentle airflow, while improving the uniformity of temperature distribution in the space, which helps to eliminate the physical discomfort caused by direct airflow.

[0041] The airflow spoiler 20 can be configured as various mechanical actuators to achieve airflow regulation functions, including but not limited to the following two preferred embodiments:

[0042] The first type of turbulence actuator adopts a telescopic linkage structure, which includes a coaxially nested active transmission rod and a driven sleeve. When the active transmission rod is driven to rotate in the first direction, the driven sleeve generates a linear displacement along the axial direction, thereby extending out of the air guide plate 12 through the through hole 120 and turbulentizing the airflow at the air outlet, changing the flow direction and state of the airflow. Alternatively, when the active transmission rod is driven to rotate in the second direction opposite to the first direction, the driven sleeve can retract into the air guide plate 12, stopping the interference with the airflow.

[0043] The second type of turbulence actuator employs an eccentric wheel dynamic interference structure, comprising a disc-shaped base eccentrically fixed to the drive shaft. Driven by the drive shaft, the disc-shaped base can reciprocate. It can extend through the through-hole 120 on the surface of the air guide plate 12 to the outside of the air guide plate 12 and perform turbulence operation on the airflow at the air outlet, changing the direction and state of the airflow; simultaneously, the disc-shaped base can also retract into the air guide plate 12, ceasing to interfere with the airflow.

[0044] It should be noted that the above embodiments are non-exhaustive examples, and any equivalent structural deformation based on the principles of telescopic intervention or dynamic interference is within the reasonable extension scope of the technical solution of this application.

[0045] In one embodiment, the drive assembly includes a drive motor 31 and a transmission shaft 32 connected to the output end of the drive motor 31, with the turbulence-disrupting assembly 20 connected to the transmission shaft 32. The drive motor 31 can drive the transmission shaft 32 to rotate a predetermined angle according to actual needs, thereby adjusting the extension amount of the turbulence-disrupting assembly 20, thus achieving effective turbulence and precise control of the airflow at the air outlet to meet the needs of different usage scenarios and users for the air conditioning airflow effect.

[0046] Specifically, for example, when the aerodynamic actuator adopts a telescopic linkage structure, the drive motor 31 precisely controls the rotation angle of the transmission shaft 32, and this rotation angle determines the rotation amount of the active transmission rod. Different rotation amounts of the active transmission rod will result in different axial displacements of the driven sleeve. In this way, by controlling the transmission shaft 32 to rotate by a predetermined angle through the drive motor 31, the extension amount of the aerodynamic component 20 can be precisely adjusted. When the user needs a smaller or gentler airflow effect, the extension amount of the aerodynamic component 20 can be appropriately increased, while when the user needs rapid cooling, the extension amount of the aerodynamic component 20 can be reduced or the aerodynamic component 20 can be omitted.

[0047] For example, when the turbulence actuator adopts an eccentric wheel structure, the disc-shaped base is connected to the drive shaft 32. When the drive motor 31 drives the drive shaft 32 to rotate by a predetermined angle, the disc-shaped base will change position under the action of the eccentric structure. Different predetermined angles by which the drive motor 31 controls the drive shaft 32 to rotate result in different positions of the disc-shaped base during the eccentric circular motion, and also different degrees of extension beyond the guide plate 12. For instance, when the drive motor 31 drives the drive shaft 32 to rotate to a certain angle, a larger portion of the disc-shaped base extends beyond the guide plate 12, resulting in a stronger turbulence effect on the airflow at the outlet; when the drive motor 31 drives the drive shaft 32 to rotate to another angle, a larger portion of the disc-shaped base retracts into the guide plate 12, correspondingly weakening the turbulence effect on the airflow. In this way, the drive motor 31 drives the drive shaft 32 to rotate by a predetermined angle, thereby adjusting the extension amount of the second type of turbulence actuator.

[0048] In one embodiment, reference Figure 3 This is a schematic diagram of the drive assembly. The drive assembly's transmission shaft 32 includes a first transmission shaft 321 and a second transmission shaft 322. The first transmission shaft 321 serves as the main drive shaft, and one end of it can be connected to the output end of the drive motor 31 via a coupling. The second transmission shaft 322 serves as the driven shaft, and its axis is arranged parallel to and spaced apart from the first transmission shaft 321. The two are connected by a gear pair or a synchronous belt pulley set. When the drive motor 31 drives the first transmission shaft 321 to rotate, the second transmission shaft 322 rotates synchronously around its own axis under the action of the gear pair or belt drive, forming a dual-shaft linkage power output mechanism.

[0049] In one embodiment, multiple turbulence components 20 are arranged in an array at a preset spacing along the axial direction of the first drive shaft 321 and the second drive shaft 322, forming a matrix of functional execution points. For example, along the length direction of the drive shaft 32, adjacent turbulence components 20 are arranged in a staggered manner. When the two drive shafts 32 rotate synchronously, each turbulence component 20 generates spatially differentiated extension and retraction movements based on its axial position and phase difference, thereby achieving dynamic balance adjustment of the airflow over the entire area of ​​the air guide plate 12.

[0050] In one embodiment, please continue to refer to Figure 3 There are two second drive shafts 322, which are respectively located on both sides of the first drive shaft 321 and are connected to the first drive shaft 321 in the middle through gear sets.

[0051] When the first drive shaft 321 rotates, the second drive shafts 322 on both sides rotate synchronously. This design allows the turbulence-disrupting component 20 to cover a wider area, enabling a high-density turbulence-intervention matrix to form on the surface of the air guide plate 12, covering nearly twice the area compared to a single-sided layout. Simultaneously, by staggering the extension and retraction of the turbulence-disrupting components on both sides—for example, one side extending while the other retracts—the regular fluctuations in airflow can be broken up, resulting in a gentler breeze. Thus, the entire drive system requires only one motor, achieving both wide-range, precise airflow control and ensuring long-term stable operation of the equipment.

[0052] To clearly illustrate the technical features of this solution, we will now use the first type of turbulence actuator, namely the telescopic linkage structure, as a non-limiting example for detailed explanation.

[0053] Specifically, refer to Figure 4 A first gear 33 is mounted on the drive shaft 32, and a second gear 34 meshes with it on the drive rod 22. Both the first gear 33 and the second gear 34 are bevel gears. When the drive shaft 32 rotates, the first gear 33 drives the second gear 34 to rotate, thereby causing the drive rod 22 to rotate as well. The surface of the drive rod 22 is provided with external threads, and the sleeve 23 has matching internal threads. When the drive rod 22 rotates, the sleeve 23 moves up and down along the direction of the threads. This telescopic sleeve 21 structure allows the turbulence-inducing component to extend or retract precisely, maintaining a compact structure while allowing for fine control of airflow strength.

[0054] In a preferred embodiment, a multi-stage telescopic sleeve 21 is used to increase the extension length of the sleeve 23 so that it can achieve a larger telescopic stroke within a limited space to turbulentize the airflow at different levels. A three-stage sleeve 23 structure will now be described in detail as a non-limiting example.

[0055] Specifically, the three-stage sleeve 23 structure adopts a nested hierarchical linkage structure and is composed of three sets of transmission rods 22 and sleeves 23, namely the first transmission rod 221 and the first sleeve 231 threadedly connected to it, the second transmission rod 222 and the second sleeve 232 threadedly connected to it, and the third transmission rod 22322 and the third sleeve 233 threadedly connected to it.

[0056] The first transmission rod 221 is connected to the transmission shaft 32, which rotates under the drive of the drive motor 31, thereby transmitting power to the first transmission rod 221, causing it to rotate around its own axis. The second transmission rod 222 is sleeved outside the first transmission rod 221 and connected to the first sleeve 231 through a rotary joint. Thus, when the first transmission rod 221 rotates, the second transmission rod 222 can rotate synchronously with it and also has a certain displacement relative to the first transmission rod 221 in the axial direction. The third transmission rod 22322 is sleeved outside the second transmission rod 222 and also connected to the second sleeve 232 through a rotary joint. Thus, when the second transmission rod 222 rotates, the third transmission rod 22322 can rotate synchronously with it and also has a certain displacement relative to the second transmission rod 222 in the axial direction. Since the nested hierarchical linkage structure and its technical principles are well-known in the field, this application will not elaborate further.

[0057] Through this hierarchical linkage method, the multi-stage telescopic sleeve can achieve a large telescopic stroke, and the extension amount of the sleeve can be precisely adjusted by controlling the rotation angle and direction of the drive motor 31 as needed, thereby achieving different levels of turbulence.

[0058] This application also provides an air conditioner, including the air conditioner indoor unit 1 as described above. Because the air conditioner indoor unit 1 has the above features and advantages, this air conditioner can improve the uniformity of temperature distribution within a space and enhance user comfort.

[0059] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
