Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to an air outlet structure and an air conditioner. Background Technology

[0002] In traditional air conditioning technology, the design of the air outlet has always been a crucial factor in air conditioning performance and user comfort. Traditional air conditioner outlets typically employ horizontal or vertical straight-line designs, or square or rectangular outlet panels. While these traditional designs meet basic airflow requirements, in actual use, this type of outlet structure suffers from uneven airflow, easily creating localized temperature differences, affecting comfort and reducing efficiency. To overcome these shortcomings, related technologies have proposed a ring-shaped air outlet design. The ring-shaped outlet forms an airflow loop around the perimeter of the outlet panel, allowing the temperature-regulating airflow to be evenly distributed into the indoor space from multiple directions, significantly improving the uniformity of airflow. However, because the ring-shaped outlet differs in shape from typical straight or rectangular outlets, traditional strip-shaped baffles are no longer suitable. This results in the ring-shaped outlet being exposed to the outside when the air conditioner is off, making it prone to dust accumulation and reducing the air conditioner's aesthetic appeal. Utility Model Content

[0003] Therefore, this utility model provides an air outlet structure and an air conditioner that can overcome the technical problem in related technologies where air conditioners with annular air outlets lack a baffle structure that matches the annular air outlet, resulting in dust accumulation at the annular air outlet.

[0004] To address the aforementioned problems, this utility model provides an air outlet structure, including an air conditioning panel and a wind deflector assembly. The air conditioning panel has an annular air outlet, and the wind deflector assembly includes an annular wind deflector plate and a deflector plate driving device. The annular wind deflector plate has a dustproof state that covers the opening of the annular air outlet and an airflow state that is outside the opening of the annular air outlet. The deflector plate driving device is used to drive the annular wind deflector plate to move closer to or further away from the annular air outlet in a linear displacement manner to realize the switching of the annular wind deflector plate between the dustproof state and the airflow state.

[0005] In some embodiments, the air conditioning panel has a first side and a second side. With reference to the orientation of the air conditioning panel assembled on the air conditioner, the first side is located outside the air conditioner and the second side is located inside the air conditioner. The annular wind deflector is located on the first side and the deflector driving device is assembled on the second side.

[0006] In some embodiments, the air conditioning panel has a central solid portion, on which a central through hole is formed, passing through the first side and the second side. The baffle driving device is a first bidirectional rotary motor. The annular baffle has a sleeve on the side near the air conditioning panel. The sleeve is threaded onto the free end of the shaft of the first bidirectional rotary motor. The sleeve and the central through hole are circumferentially limited and axially slidably connected.

[0007] In some embodiments, the air conditioning panel is further provided with an air intake grille, which is located in the area between the annular air outlet and the central through hole, and the air intake grille is arranged around the central through hole.

[0008] In some embodiments, the portion of the air conditioning panel located radially outside the annular air outlet is the outer solid portion, which is connected to the central solid portion by multiple connecting ribs, and each of the connecting ribs is evenly spaced along the circumferential direction of the central through hole.

[0009] In some embodiments, the annular windbreak includes a cross-shaped frame on its inner annular wall, and the sleeve is located in the cross intersection area of ​​the cross-shaped frame.

[0010] In some embodiments, the second side of the air conditioning panel is further provided with a sweeping assembly, which includes a plurality of guide vanes. Each guide vane is evenly spaced along the circumferential direction of the annular air outlet and is located on the air outlet path of the annular air outlet.

[0011] In some embodiments, the sweeping assembly further includes a blade deformation driving device, which includes four adjusting rings and a driving member capable of driving each adjusting ring to deflect left and right around the center of each adjusting ring by a preset angle. The four adjusting rings are respectively connected to four different positions of each guide blade, and for the same guide blade, the four adjusting rings are evenly spaced along the circumference of the guide blade.

[0012] In some embodiments, the drive unit includes a housing and four second bidirectional rotary motors located within the housing. The inner ring wall of each adjustment ring has teeth formed therein, and the shaft of each second bidirectional rotary motor has a gear. Each gear meshes with the teeth on the inner ring wall of each adjustment ring, and each adjustment ring is slidably limited to the housing.

[0013] According to an embodiment of the present invention, an air conditioner is also provided, including the above-described air outlet structure.

[0014] The air outlet structure and air conditioner provided by this utility model have the following beneficial effects:

[0015] The baffle drive device drives the annular baffle to move closer to or away from the annular air outlet in a linear displacement manner, thereby achieving the switching between dustproof state and air flow state. The structural design and state switching control are very simple. It can simplify the structural design of the air conditioner and reduce manufacturing costs while achieving dust protection when the air conditioner is turned off.

[0016] By placing the annular wind deflector on the outer surface of the air conditioner panel and the deflector drive device on the inner surface of the air conditioner panel, the consistency of the external structure of the air conditioner can be improved, thereby enhancing the aesthetic appearance of the air conditioner.

[0017] The first bidirectional rotary motor's shaft and the sleeve on the annular baffle plate are threaded together to form a nut screw transmission pair. The circumferential rotation between the sleeve and the central through hole limits the rotational displacement of the first bidirectional rotary motor, thereby converting the rotational displacement of the annular baffle plate into the linear displacement of the annular baffle plate. This achieves the telescopic movement of the annular baffle plate, resulting in a simple and compact structure.

[0018] Four adjustment rings connect the four different areas of each air guide vane into a whole. By controlling the different positions of the four adjustment rings, the torsional deformation of each air guide vane can be achieved, thereby flexibly adjusting the airflow direction of the annular air outlet. This type of air-sweeping assembly achieves arbitrary airflow direction adjustment of the air guide vanes by stretching or compressing the different positions of each air guide vane through the adjustment rings. For example, by controlling the compression and stretching of the left and right adjustment rings, preliminary left and right airflow direction adjustment can be achieved; by controlling the compression and stretching of the up and down adjustment rings, preliminary up and down airflow direction adjustment can be achieved. In practical applications, it can also be combined with an intelligent airflow regulator to achieve unlimited adjustment of the panel airflow direction, realizing true 360° airflow adjustment. Users can precisely adjust the airflow direction according to actual needs, meeting the personalized needs of different users for air distribution, thereby effectively improving the comfort of air conditioning.

[0019] The aforementioned design of the air-sweeping component and the annular air outlet optimizes the airflow path and improves airflow efficiency, making the airflow path smoother and more efficient. Traditional air conditioner air outlet structures often have problems such as high airflow resistance (the air outlet has sharp edges) and uneven flow, which limits the cooling and heating effects of the air conditioner. This utility model, through the annular air outlet and optimized airflow design, reduces the generation of eddies and energy loss caused by air obstruction due to the relatively smooth annular edge, thereby significantly reducing airflow resistance and improving the overall air circulation efficiency of the air conditioner. This allows the air conditioner to cool or heat more efficiently during operation and reduces energy waste. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0030] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0032] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, an air outlet structure is provided, including an air conditioning panel 1 and a wind deflector assembly (not shown in the figure). An annular air outlet 11 is formed on the air conditioning panel 1. The wind deflector assembly includes an annular wind deflector plate 21 and a deflector driving device (not shown in the figure). The annular wind deflector plate 21 has a dustproof state covering the opening of the annular air outlet 11 and an airflow state outside the opening of the annular air outlet 11. The deflector driving device is used to drive the annular wind deflector plate 21 to move closer to or further away from the annular air outlet 11 in a linear displacement manner to switch the annular wind deflector plate 21 between the dustproof state and the airflow state. Specifically... Figure 2The indicated orientation is for reference. The baffle drive device can drive the annular baffle 21 to extend and retract linearly in the left and right directions, thereby realizing the on / off control switching of the annular baffle 21 to the annular air outlet 11.

[0033] In this technical solution, the annular baffle 21 is driven by a baffle driving device to move closer to or further away from the annular air outlet 11 in a linear displacement manner, thereby achieving the switching between dustproof and airflow states. The structural design and state switching control are very simple, simplifying the structural design of the air conditioner and reducing manufacturing costs while ensuring dust prevention and protection when the air conditioner is off. It is worth emphasizing that the annular air outlet 11 in this utility model forms an annular airflow path, which greatly improves the uniformity of airflow. The annular air outlet 11 design ensures a more uniform distribution of air in the room, avoiding local overcooling or overheating, improving the cooling / heating efficiency of the air conditioner, and enabling the entire room to reach the set temperature more quickly and evenly.

[0034] In some embodiments, the air conditioning panel 1 has a first side (not labeled in the figure) and a second side (not labeled in the figure). With reference to the orientation of the air conditioning panel 1 assembled on the air conditioner, the first side is located on the outside of the air conditioner and the second side is located on the inside of the air conditioner. The annular wind deflector 21 is located on the first side and the deflector driving device is assembled on the second side. It can be understood that the aforementioned first side can be referred to as the outer side and the second side can be referred to as the inner side.

[0035] In this technical solution, the annular wind deflector 21 is set on the outer side of the air conditioner panel 1, while the deflector driving device is set on the inner side of the air conditioner panel 1. This can improve the consistency of the external structure of the air conditioner and thus enhance its aesthetic appearance.

[0036] In some embodiments, the air conditioning panel 1 has a central solid portion (not shown in the figure), on which a central through hole 12 is formed, penetrating the first side and the second side. The baffle driving device is a first bidirectional rotary motor (not shown in the figure). The annular baffle 21 has a sleeve 211 on the side near the air conditioning panel 1. The sleeve 211 is threaded onto the free end of the shaft of the first bidirectional rotary motor, that is, an external thread is formed on the free end of the shaft of the first bidirectional rotary motor, and the sleeve 21... An internal thread is formed on the inner wall of the sleeve 211. The sleeve 211 and the central through hole 12 are circumferentially limited and axially slidably connected. Specifically, a groove extending axially is provided on the outer wall of the sleeve 211, and a protrusion extending axially is provided on the inner wall of the central through hole 12. The protrusion is slidably connected in the groove, thereby enabling the axial sliding connection between the sleeve 211 and the central through hole 12 while restricting the circumferential rotation of the sleeve 211. The aforementioned first bidirectional rotary motor is also a rotary motor that can be controlled to switch between forward and reverse rotation.

[0037] In this technical solution, the rotating shaft of the first bidirectional rotary motor and the sleeve 211 on the annular baffle 21 are threaded together to form a nut screw transmission pair. The sleeve 211 and the central through hole 12 are circumferentially rotated and limited, so that the rotational displacement of the first bidirectional rotary motor is converted into the linear displacement of the annular baffle 21, that is, the telescopic movement of the annular baffle 21 is realized. The structure is simple and compact.

[0038] In some embodiments, the air conditioning panel 1 is further provided with an air intake grille 13, which is located in the area between the annular air outlet 11 and the central through hole 12, and the air intake grille 13 is arranged around the central through hole 12.

[0039] In this technical solution, by placing the air intake grille 13 on the central area of ​​the air conditioning panel 1, the structural design of the air conditioner can be further simplified.

[0040] In some embodiments, the portion of the air conditioning panel 1 located radially outside the annular air outlet 11 is the outer solid portion (not indicated in the figure). The outer solid portion and the central solid portion are connected as one unit by multiple connecting ribs 14, and each of the connecting ribs 14 is evenly spaced along the circumferential direction of the central through hole 12. The size and number of the aforementioned connecting ribs 14 can be reasonably selected according to the actual structural strength requirements.

[0041] In this technical solution, the annular air outlet 11 can be directly formed on the planar air conditioning panel 1, further simplifying the design of the air outlet structure.

[0042] In some embodiments, the annular baffle 21 includes a cross skeleton 212 on its inner annular wall, and the sleeve 211 is located in the cross intersection area of ​​the cross skeleton 212. It is understood that the central area of ​​the aforementioned annular baffle 21 objectively forms a large flow passage area, which corresponds to the setting position of the aforementioned air inlet grille 13, and can ensure the air inlet flow of the air inlet grille 13.

[0043] In some embodiments, the second side of the air conditioning panel 1 is also provided with a sweeping assembly 3, which is used to guide the airflow from the annular air outlet 11 at different angles. The sweeping assembly 3 includes a plurality of guide vanes 31, each of which is evenly spaced along the circumference of the annular air outlet 11 and is located on the air outlet path of the annular air outlet 11, thereby realizing the adjustment of the air supply direction and improving the user's comfort.

[0044] In some embodiments, the sweeping assembly 3 further includes a blade deformation driving device (not shown in the figure). The blade deformation driving device includes four adjusting rings 32 and a driving member 33 capable of driving each adjusting ring 32 to deflect left and right around the center of each adjusting ring 32 by a preset angle. The aforementioned preset angle can be reasonably selected according to the number of guide vanes 31 and the torsion angle of each guide vane 31. For example, the preset guiding angle of each guide vane 31 can be 30° to 90°. The four adjusting rings 32 are respectively connected to four different positions of each guide vane 31, and for the same guide vane 31, the four adjusting rings 32 are evenly spaced along the circumference of the guide vane 31. See details. Figure 5 As shown, taking the guide vane 31 as a circle as an example, the four adjustment rings 32 are respectively connected to the four edges of the circular guide vane, and the aforementioned adjustment rings 32 can be bonded to each guide vane 31 as a whole.

[0045] In this technical solution, four different areas of each guide vane 31 are connected in series into a whole by four adjusting rings 32. The torsional deformation of each guide vane 31 can be achieved by controlling the different positions of the four adjusting rings 32, thereby flexibly adjusting the airflow direction of the annular air outlet 11. This type of air-sweeping assembly 3 achieves arbitrary airflow direction adjustment of the guide vanes 31 by stretching or compressing different positions of each guide vane 31 through the adjusting rings 32. For example, by controlling the left and right (within...) Figure 5By compressing and stretching the adjustment ring (shown as a reference), preliminary left-right airflow adjustment can be achieved; by controlling the compression and stretching of the up-down adjustment ring 32, preliminary up-down airflow adjustment can be achieved. In specific applications, it can also be combined with an intelligent airflow regulator to achieve unlimited adjustment of the panel airflow direction, realizing true 360° air supply adjustment. Users can precisely adjust the airflow direction according to actual needs, meeting the personalized needs of different users for air distribution, thereby effectively improving the comfort of the air conditioner.

[0046] It is also understandable that the design of the aforementioned air-sweeping component 3 and the annular air outlet 11 optimizes the airflow path and improves airflow efficiency, making the airflow path smoother and more efficient. Traditional air conditioner outlet structures often have problems such as high airflow resistance (the outlet has sharp edges) and uneven flow, which limits the cooling and heating effects of the air conditioner. This utility model, through the annular air outlet 11 and the optimized airflow design, reduces the generation of eddies and energy loss caused by air obstruction due to the relatively smooth annular edge, thereby significantly reducing airflow resistance and improving the overall airflow efficiency of the air conditioner. This allows the air conditioner to cool or heat more efficiently during operation and reduces energy waste.

[0047] As a feasible implementation, the drive component 33 includes a housing (not shown in the figure) and four second bidirectional rotary motors (not shown in the figure) located within the housing. Each adjusting ring 32 has teeth formed on its inner ring wall (not shown in the figure; here, the adjusting ring 32 is also a circular rack). Each second bidirectional rotary motor has a gear (not shown in the figure) on its shaft. Each gear meshes with the teeth on the inner ring wall of each adjusting ring 32, and each adjusting ring 32 is slidably limited to the housing to ensure smooth position adjustment of each adjusting ring 32. Each second bidirectional rotary motor is independently controlled. When the second bidirectional rotary motor is running, each gear drives the meshing adjusting ring 32 to rotate a certain circumferential displacement to the left or right, thereby stretching or compressing the corresponding position of the connected guide vane 31, ultimately achieving adjustment of different sweeping angles and guide angles. To further ensure the structural stability of the sweeping assembly 3, while the housing is fixedly connected to the second side, each adjusting ring 32 is also slidably connected to a corresponding limiting block on the second side.

[0048] The design of the annular air outlet 11 in this utility model breaks away from the traditional single form of square or rectangular air outlets. Its streamlined design not only improves airflow efficiency functionally but also adds a modern touch, making it better suited for modern home and commercial environments. Market research shows that 60% of consumers prefer air conditioners with an annular air outlet design, believing it to be more modern and artistic, and better integrated with modern home styles.

[0049] The aforementioned air conditioner panel 1 is made of high-strength lightweight alloy material or ABS plastic. Its surface can be sprayed or coated to meet different aesthetic requirements. In one specific embodiment, the air conditioner panel 1 is circular in shape, with the air inlet of the air conditioner, i.e., the aforementioned air inlet grille 13, at its center. An annular air outlet 11 is provided around the perimeter, which can be divided into multiple fan-shaped air outlets by multiple connecting ribs 14. The diameter and thickness of the air conditioner panel 1 are selected according to the power of the air conditioner, room size, and other requirements. The design of the air conditioner panel 1 considers not only functionality but also aesthetics, ensuring that the air conditioner can adapt to various home or commercial environments.

[0050] According to an embodiment of the present invention, an air conditioner is also provided, including the above-described air outlet structure. In one specific embodiment, the air conditioner is a ceiling-mounted unit.

The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
