Baffle assembly, ducted air conditioner and air conditioning equipment

Abstract

This application relates to a baffle assembly, a duct air conditioner, and an air conditioning unit. The baffle assembly includes a hinged base, a first baffle, a second baffle, and a drive assembly. The first baffle is rotatably mounted on the hinged base. The second baffle is slidably connected to the first baffle, and the relative sliding direction between the second baffle and the first baffle is perpendicular to the rotation axis of the first baffle. The drive assembly is connected to both the first and second baffles. The first and second baffles in the baffle assembly provided by this application can rotate within the housing, enabling position adjustment of the main structure of the baffle assembly. This provides sufficient space for the rotation of the volute assembly within the housing. The relative sliding direction between the second baffle and the first baffle is perpendicular to the rotation axis of the first baffle, which reduces the overall swing radius of the baffle assembly, further reducing its space occupancy. It also further reduces the risk of interference with the volute assembly, helping to ensure that the dimensions of the volute assembly are not affected by interference.

Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a baffle assembly, duct air conditioner and air conditioning equipment. Background Technology

[0002] In the prior art, in order to adjust the air outlet direction, multiple air outlets with different orientations are opened on the casing of the indoor unit (such as a ducted air conditioner). By rotating the volute assembly inside the casing of the indoor unit, different air outlet states can be switched (for example, switching from side air outlet to bottom air outlet, or vice versa), which can achieve different air outlet effects of cold air and hot air.

[0003] After the volute assembly rotates to a different position, it needs to seal against the baffle to form a stable return air area or outlet air area, preventing air leakage. Since most baffles are currently fixed, the large overall rotation size of the volute assembly can interfere with the baffle during rotation. To avoid this interference, the size of the volute assembly must be reduced while keeping the outer casing size constant, which affects the overall operating efficiency of the fan equipped with the volute assembly.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0029] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0030] To address the technical problem in the prior art where the volute assembly 6 easily interferes with the fixed baffle when rotating, this application provides a baffle assembly, a ducted air conditioner, and an air conditioning device. The baffle assembly includes a hinged base 1, a first baffle 2, a second baffle 3, and a drive assembly 4. The first baffle 2 is rotatably mounted on the hinged base 1, and the second baffle 3 is slidably connected to the first baffle 2. This allows for the extension and retraction of the main structure of the baffle assembly, which helps to reduce the coverage area when the main structure of the baffle assembly rotates. The rotation of the baffle assembly can avoid interference with the volute assembly 6, eliminating the need to reduce the size of the volute assembly 6 and ensuring the working efficiency of the indoor unit (such as a ducted air conditioner).

[0031] Please see Figures 1 to 15 The first aspect of this application provides a baffle assembly, including a hinge base 1, a first baffle 2, a second baffle 3, and a drive assembly 4. The hinge base 1 is used to achieve a fixed connection between the baffle assembly and the housing 5 of the indoor unit, thereby enabling the baffle assembly to be installed entirely inside the housing 5. The first baffle 2 is rotatably mounted on the hinge base 1 and can rotate inside the housing 5, allowing for position adjustment of the main structure of the baffle assembly and providing sufficient space for the rotation of the volute assembly 6 inside the housing 5. Figure 2 , Figure 4 and Figure 6 As shown.

[0032] The second baffle 3 is slidably connected to the first baffle 2, such as Figure 1 , Figure 2 and Figure 7 As shown, the second baffle 3 can not only rotate synchronously with the first baffle 2, but also slide to extend and retract the main structure of the baffle assembly, thereby adjusting the overall space occupancy of the baffle assembly. Furthermore, the relative sliding direction between the second baffle 3 and the first baffle 2 is perpendicular to the rotation axis of the first baffle 2. When the first baffle 2 rotates, the second baffle 3 can move towards the rotation axis of the first baffle 2, reducing the overall swing radius of the baffle assembly (i.e., the size of the baffle assembly in the sliding direction of the second baffle 3). This reduces the coverage area when the main structure of the baffle assembly rotates, further preventing interference between the baffle assembly and / or the volute assembly 6 during rotation. This eliminates the need to reduce the size of the volute assembly 6, which helps ensure the working efficiency of the fan.

[0033] The drive component 4 is connected to the first baffle 2 and the second baffle 3 respectively, and can drive the first baffle 2 to rotate and drive the second baffle 3 to slide, thereby realizing the automatic rotation and extension of the baffle assembly.

[0034] It should be noted that the baffle assembly of this application splits the traditional fixed baffle into two relatively sliding baffles (i.e., the first baffle 2 and the second baffle 3), and the first baffle 2 can drive the second baffle 3 to rotate synchronously to make way. When the internal space of the indoor unit housing 5 is limited, the movable baffle assembly can avoid the risk of interference with the volute assembly 6.

[0035] Meanwhile, the second baffle 3 is slidably connected to the first baffle 2, and the relative sliding direction of the second baffle 3 and the first baffle 2 is perpendicular to the rotation axis of the first baffle 2. This allows the second baffle 3 to move toward the rotation axis of the first baffle 2 when the first baffle 2 rotates to make way, further reducing the space occupancy of the baffle assembly. The swing radius of the baffle assembly is reduced, and the risk of interference with the volute assembly 6 is further reduced. Compared with pure fixed baffle or pure rotating baffle solutions, this application can accommodate a larger volute assembly 6 in the same housing 5 space, thereby improving the airflow adjustment range of the indoor unit.

[0036] In some embodiments of this application, please refer to Figure 7 , Figure 8 , Figure 10 , Figure 12 and Figure 13 The first baffle 2 is provided with a first guide part 21, and the second baffle 3 is provided with a second guide part 31. The first guide part 21 and the second guide part 31 are matched and slidably connected. The relative sliding direction of the first guide part 21 and the second guide part 31 is perpendicular to the rotation axis of the first baffle 2. This can make the guiding direction of the first guide part 21 and the second guide part 31 consistent with the relative sliding direction between the second baffle 3 and the first baffle 2, which can ensure the motion accuracy and reliability of the second baffle 3 when sliding relative to the first baffle 2.

[0037] It should be noted that, through the cooperation of the first guide part 21 and the second guide part 31, this application can not only realize the sliding connection between the first baffle 2 and the second baffle 3, but also ensure the stability and reliability of the sliding of the second baffle 3 relative to the first baffle 2, and avoid the second baffle 3 from tilting or getting stuck during the sliding process, which is conducive to ensuring the reliability of the extension and retraction of the main structure of the baffle assembly.

[0038] In some embodiments of this application, please refer to Figure 7 and Figure 8 The first guide portion 21 and the second guide portion 31 are in a concave-convex fit, which can increase the contact area between the first guide portion 21 and the second guide portion 31, thereby ensuring the accuracy of sliding guidance achieved through the cooperation of the first guide portion 21 and the second guide portion 31.

[0039] In some embodiments of this application, please refer to Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The first guide section 21 includes a plurality of slide rails 211 arranged sequentially along the length direction of the first baffle 2, and the second guide section 31 includes a plurality of slide grooves 311 arranged sequentially along the length direction of the second baffle 3. The plurality of slide rails 211 and the plurality of slide grooves 311 are arranged in a one-to-one correspondence, which can realize multi-point guiding cooperation between the first baffle 2 and the second baffle 3.

[0040] Since both the first baffle 2 and the second baffle 3 are long strip-shaped plates, and the length direction of the first baffle 2 is parallel to the length direction of the rotation axis of the first baffle 2, the sliding accuracy of the two long strip-shaped plates in the direction perpendicular to their length direction can be improved by the cooperation of multiple slide rails 211 and multiple slide grooves 311 arranged along the length direction of the plate. The second baffle 3 will not have a skewed phenomenon of one end moving first and the other end lagging behind during the sliding process.

[0041] It should be noted that this application achieves multi-point guidance by setting multiple slide rails 211 and multiple slide grooves 311 in corresponding cooperation, which can form continuous constraint in the direction in which the long strip plate is most likely to deviate. During the sliding process of the second baffle 3, the plate will not twist or shake, and it is not easy to have loosening caused by unilateral wear during long-term use.

[0042] In some embodiments of this application, please refer to Figure 8 and Figure 13 The slide rail 211 and the slide groove 311 both have T-shaped cross sections, which can prevent the slide rail 211 from coming out of the slide groove 311, which helps to ensure a reliable connection between the first baffle 2 and the second baffle 3, and prevents the second baffle 3 from detaching from the first baffle 2.

[0043] It should be noted that, in order to prevent the slide rail 211 from coming out of the slide groove 311, the cross-sections of the slide rail 211 and the slide groove 311 can also be set to dovetail shape, I-shaped shape, etc., which can achieve the purpose of this application.

[0044] In some preferred embodiments of this application, multiple slide rails 211 are evenly or symmetrically arranged along the length direction of the first baffle 2, and multiple slide grooves 311 are evenly or symmetrically arranged along the length direction of the second baffle 3. This can ensure uniform force transmission between the first baffle 2 and the second baffle 3, thereby ensuring the stability of the relative sliding between the two.

[0045] In some embodiments of this application, please refer to Figure 7 and Figure 9The first baffle 2 and the second baffle 3 are arranged in parallel, and the side surface of the first baffle 2 facing the second baffle 3 has a protruding stop 22, which can be used as a mechanical limiting structure to slide and limit the second baffle 3, thereby limiting the sliding stroke of the second baffle 3 and preventing the second baffle 3 from colliding with the hinge base 1 or other components inside the housing 5.

[0046] In some embodiments of this application, please refer to Figure 9 The stop portion 22 has an elastic pad (not shown in the figure) on the side facing the second baffle 3. This pad can be used to buffer the second baffle 3, prevent rigid impact between the second baffle 3 and the stop portion 22, and prevent the impact of the second baffle 3 from damaging the stop portion 22. At the same time, it can also reduce the noise when the second baffle 3 collides with the stop portion 22, and prevent abnormal noise.

[0047] In some embodiments of this application, please refer to Figure 5 , Figure 9 , Figure 11 , Figure 14 and Figure 15 The drive assembly 4 includes a first drive member 41 and a second drive member 42. The first drive member 41 is disposed on the hinge base 1 and connected to the first baffle 2, and can drive the first baffle 2 to rotate relative to the hinge base 1. The second drive member 42 is disposed on the first baffle 2 and connected to the second baffle 3, and can drive the second baffle 3 to slide relative to the first baffle 2.

[0048] It should be noted that the first baffle 2 and the second baffle 3 are driven by the first driving member 41 and the second driving member 42 respectively, and can be adjusted independently. The baffle assembly can be extended or retracted by sliding the second baffle 3 first, and then the first baffle 2 can be rotated to make way; or the first baffle 2 can be rotated first to make way, and then the second baffle 3 can be slid to extend or retract the baffle assembly; or the second baffle 3 can be extended or retracted while the first baffle 2 is rotating. All of these methods can achieve the purpose of this application.

[0049] In some embodiments of this application, please refer to Figure 11 and Figure 15 The drive assembly 4 also includes a drive shaft 43, which is rotatably mounted on the hinge base 1. One end of the drive shaft 43 is connected to the first drive member 41, and the drive shaft 43 can be rotated by the first drive member 41. The other end of the drive shaft 43 is connected to the first baffle 2, and the first baffle 2 can be rotated synchronously, thereby realizing the overall swing and position change of the first baffle 2 and the second baffle 3.

[0050] In some embodiments of this application, both ends of the first baffle 2 along its length are provided with hinge bases 1, and both ends of the first baffle 2 are rotatably connected to the hinge bases 1 via a drive shaft 43, which can achieve stable installation of the long strip plate-like component (i.e., the first baffle 2); at least one of the two hinge bases 1 at both ends of the first baffle 2 is provided with a first drive member 41, which can drive the first baffle 2 to rotate relative to the hinge base 1.

[0051] In the above embodiments, the drive shaft 43 and the first baffle 2 can be fixedly connected or detachably connected. As long as the drive shaft 43 can drive the first baffle 2 to rotate synchronously, the purpose of this application can be achieved.

[0052] Please refer to some preferred embodiments of this application. Figure 11 and Figure 15 The first baffle 2 has insertion holes 23 at both ends. The cross-section of the insertion holes 23 is non-circular. The end of the drive shaft 43 near the first baffle 2 is matched with the insertion hole 23. The first baffle 2 and the drive shaft 43 are detachably connected. When one end of the drive shaft 43 is inserted into the insertion hole 23, the non-circular cross-section of the insertion hole 23 can prevent relative rotation between the first baffle 2 and the drive shaft 43, thus ensuring the reliability of the synchronous rotation of the first baffle 2 driven by the drive shaft 43.

[0053] Meanwhile, a detachable connection between the drive shaft 43 and the first baffle 2 is achieved through a plug-in method, facilitating the assembly of the first baffle 2, the drive shaft 43, and the hinge base 1. Specifically, one end of the drive shaft 43 passes through the mounting hole of the hinge base 1 and is fixedly connected to the first drive component 41. Then, the plug-in hole 23 of the first baffle 2 is plugged into the end of the drive shaft 43 away from the hinge base 1, which improves the ease of assembly between the first baffle 2, the hinge base 1, and the drive assembly 4.

[0054] In the above embodiments, the sliding drive of the second baffle 3 can be driven by linear actuators such as hydraulic cylinders, or by components such as gear assemblies, timing belt assemblies and sprocket assemblies, all of which can achieve the purpose of this application.

[0055] Please refer to some preferred embodiments of this application. Figure 9 and Figure 15 The drive assembly 4 also includes a drive gear 44, and a second drive member 42 is connected to the drive gear 44. The second baffle 3 has a rack portion 32 extending along its sliding direction on the side facing the drive gear 44. The rack portion 32 is connected to the drive gear 44 in a transmission manner. The second drive member 42 drives the drive gear 44 to rotate, and the drive gear 44 is connected to the rack portion 32 in a transmission manner to drive the rack portion 32, thereby causing the second baffle 3 to slide relative to the first baffle 2.

[0056] It should be noted that, due to the advantages of gear transmission, such as stable transmission and high precision, this application uses a drive gear 44 to drive the second baffle 3 to slide via a transmission connection with the rack portion 32 on the second baffle 3. This facilitates precise control of the sliding position of the second baffle 3. Compared with using drive components such as hydraulic cylinders, the structure is simpler and the cost is lower.

[0057] In some embodiments of this application, please refer to Figure 9 and Figure 15 The first baffle 2 has a receiving groove 24, and the drive gear 44 is disposed inside the receiving groove 24. The receiving groove 24 can protect the drive gear 44. The rack part 32 of the second baffle 3 is disposed on the side of the second baffle 3 facing the receiving groove 24. The second baffle 3 can close the opening of the receiving groove 24 to prevent foreign objects from entering the receiving groove 24 and affecting the transmission connection between the drive gear 44 and the rack part 32.

[0058] It should be noted that this application protects the drive gear 44 by using the receiving groove 24 opened on the first baffle 2, and the second baffle 3 can act as a sliding cover to close the opening of the receiving groove 24. This can achieve the enclosure and protection of the transmission connection between the drive gear 44 and the rack part 32, and can prevent foreign objects such as dust, condensate, and debris inside the housing 5 from directly contacting the drive gear 44 and the rack part 32, thus preventing the tooth surface of the drive gear 44 or the rack part 32 from being contaminated or worn, and preventing the transmission accuracy from decreasing due to environmental degradation.

[0059] In the above embodiments, the drive gear 44 can directly mesh with the rack portion 32, such as... Figure 5 and Figure 9 As shown, other gears can also be provided between the drive gear 44 and the rack section 32 for transmission, such as... Figure 14 and Figure 15 As shown, both can drive the second baffle 3 to slide in a direction perpendicular to the rotation axis of the first baffle 2.

[0060] In some embodiments of this application, please refer to Figure 14 and Figure 15 The drive assembly 4 also includes a speed change gear 45, which is rotatably disposed inside the receiving groove 24 and meshes with the drive gear 44 and the rack portion 32 respectively. When the rotational speed of the output shaft of the second drive member 42 and the drive gear 44 does not meet the sliding speed requirements of the second baffle 3, the speed can be reduced or increased by the speed change gear 45, so that the sliding speed of the second baffle 3 relative to the first baffle 2 is maintained within a suitable range.

[0061] Specifically, when the rotational speed of the second driving component 42 is too high and deceleration is required, the diameter of the transmission gear 45 is larger than the diameter of the driving gear 44, allowing the second baffle 3 to slide at a slower speed. When the rotational speed of the second driving component 42 is too low and speed increase is required, the diameter of the transmission gear 45 is smaller than the diameter of the driving gear 44, allowing the second baffle 3 to slide at a faster speed.

[0062] In some embodiments of this application, please refer to Figure 14 and Figure 15 The drive assembly 4 also includes a rotating shaft 46 disposed inside the receiving groove 24. A transmission gear 45 is coaxially disposed on the rotating shaft 46. When the rotating shaft 46 is fixedly connected to the interior of the receiving groove 24, the transmission gear 45 is rotatably disposed on the rotating shaft 46 and can rotate relative to the rotating shaft 46 under the drive of the drive gear 44. When both ends of the rotating shaft 46 are rotatably connected to the inner wall of the receiving groove 24, the transmission gear 45 is coaxially fixedly connected to the rotating shaft 46, and the drive gear 44 can drive the transmission gear 45 and the rotating shaft 46 to rotate synchronously, thus achieving the purpose of this application.

[0063] In some embodiments of this application, the sliding stroke of the second baffle 3 is between 25 and 40 mm, the rotation angle of the first baffle 2 is between 75° and 90°, and the diameter of the drive gear 44 and the transmission gear 45 is preferably between 10 and 15 mm, which can ensure that the size of the baffle assembly meets the usage requirements.

[0064] In some embodiments of this application, when the first drive member 41 and the second drive member 42 both use the same motor, if the rotation speeds of the first drive member 41 and the second drive member 42 are the same, the time required for the second baffle 3 to complete sliding is more than 1.6 times the time required for the first baffle 2 to complete rotation, so that the total time required for the baffle assembly to complete rotation and extension is about 15 seconds. Therefore, before the first drive member 41 of the first baffle 2 is started, the second drive member 42 can be started in advance (for example, 10 seconds in advance), so that the second baffle 3 can slide into position (i.e., synchronized position) when the baffle assembly is rotated into position, ensuring that the baffle assembly operates smoothly as a whole, without waiting for the second baffle 3 to retract into position.

[0065] In some embodiments of this application, please refer to Figure 7 , Figure 10 and Figure 12 Both ends of the first baffle 2 are provided with receiving grooves 24 for accommodating two sets of gear transmission structures (i.e., the second driving member 42, the driving gear 44, and the rack part 32, and if necessary, a speed-changing gear 45), thereby achieving stable and reliable driving of both ends of the second baffle 3 in the length direction. The receiving grooves 24 are located on the side of the first baffle 2 away from the hinge base 1, so that when the baffle assembly is fully extended, the opening of the receiving groove 24 can be blocked by the side of the second baffle 3 near the hinge base 1.

[0066] In some embodiments of this application, please refer to Figure 9 and Figure 11 The first baffle 2 also includes a sealing plate 25, which covers part of the opening of the receiving groove 24 and can cover part of the receiving groove 24. The projections of the sealing plate 25 and the drive gear 44 on the second baffle 3 do not overlap. When the drive gear 44 directly meshes with the rack part 32, the sealing plate 25 can avoid interfering with the transmission between the drive gear 44 and the rack part 32.

[0067] In other embodiments of this application, please refer to Figure 9 and Figure 11 The projections of the sealing plate 25 and the speed-changing gear 45 on the second baffle 3 do not overlap. When the drive gear 44 achieves transmission through the speed-changing gear 45, and the speed-changing gear 45 directly meshes with the rack portion 32, the sealing plate 25 can avoid interfering with the transmission between the speed-changing gear 45 and the rack portion 32.

[0068] It should be noted that when the baffle assembly is fully extended, if the opening of the receiving groove 24 needs to be blocked by the second baffle 3, the dimension of the second baffle 3 in the sliding direction needs to be set relatively large to achieve complete coverage of the opening of the receiving groove 24. However, after setting the sealing plate 25, other opening areas outside the areas where the drive gear 44 and the transmission gear 45 are located can be blocked by the sealing plate 25. The second baffle 3 only needs to have the rack portion 32 protrude towards the direction of the hinge base to block the drive gear 44 and / or the transmission gear 45. Figure 9 As shown, there is no need to increase the size of the second baffle 3 as a whole, which helps to reduce the mass of the second baffle 3, thereby reducing the energy consumption of the second drive component 42 and the first drive component 41.

[0069] In the above embodiments, the baffle assembly can automatically rotate and extend. Before the volute assembly 6 rotates, the first baffle 2 in the baffle assembly can drive the second baffle 3 to rotate to make way, and the second baffle 3 can slide relative to the first baffle 2 to retract the baffle assembly, reserving enough rotation space for the volute assembly 6 to rotate. This can avoid the risk of interference between the baffle assembly and the volute assembly 6, and help ensure that the size of the volute assembly 6 can be set large enough, thereby ensuring the working efficiency of the fan and indoor unit equipped with the volute assembly 6.

[0070] Please see Figures 1 to 15The second aspect of this application provides a duct machine, including the baffle assembly described in the above embodiments, and also including a housing 5 and a volute assembly 6. The hinge base 1 is fixedly disposed on the housing 5 and can be used to realize the fixed installation of the hinge base 1 inside the housing 5, thereby realizing the fixation of the rotation axis of the first baffle 2 and ensuring the accuracy and reliability of the overall rotation of the first baffle 2 and the second baffle 3.

[0071] The volute assembly 6 is rotatably disposed inside the housing 5, and can be rotated relative to the housing 5 by rotating the base frame 8. Figure 1 As shown, this allows for the switching of the air outlet direction, enabling the air blown from the volute assembly 6 to exit through the side air outlet 51 or the bottom air outlet 52 of the housing 5. The second baffle 3 has a first sealing abutment part 33 on the side away from the hinge base 1, and the volute assembly 6 has a second sealing abutment part 61 that matches the first sealing abutment part 33. When the volute assembly 6 is rotated into position, the first sealing abutment part 33 and the second sealing abutment part 61 cooperate to form a seal, separating the return air area and the air inlet area, preventing air leakage, and thus ensuring the air intake or exhaust efficiency of the ducted air conditioner.

[0072] It should be noted that the baffle assembly of this application can serve as either an upper baffle or a lower baffle, both of which can be used to achieve contact and avoidance with the volute assembly 6. Specifically, when the baffle assembly serves as an upper baffle, it can abut against the volute assembly 6 on the upper side of the housing 5, such as... Figure 2 and Figure 3 As shown, when the side air outlet mode is used, the baffle assembly and the outer wall of the volute assembly 6 abut against each other, which can form a stable air outlet cavity and avoid air leakage.

[0073] In some embodiments of this application, please refer to Figure 2 and Figure 3 The first sealing abutment part 33 includes a first sealing abutment surface 331 and a second sealing abutment surface 332, and the first sealing abutment surface 331 and the second sealing abutment surface 332 are set at an angle, so that they can abut against the second sealing abutment part 61 from different directions, thereby improving the sealing reliability between the second baffle 3 and the volute assembly 6.

[0074] It should be noted that this application can seal the second sealing contact portion 61 on the volute assembly 6 from different directions using the first sealing contact surface 331 and the second sealing contact surface 332 on the second baffle 3, which is beneficial to improving the sealing effect. Even if there is a slight positional deviation when the volute assembly 6 is rotated into position, at least one sealing contact surface can be guaranteed to be in contact with it, such as... Figure 3 As shown, this can improve the sealing and contact tolerance between the second baffle 3 and the volute assembly 6.

[0075] In some embodiments of this application, please refer to Figure 4 and Figure 5 The inner wall of the housing 5 is provided with a buffer component 7 corresponding to the baffle assembly. When the first baffle 2 and the second baffle 3 in the baffle assembly rotate to the end position, they come into contact with the buffer component 7, which can prevent the baffle assembly from directly impacting the housing 5 after rotating and moving.

[0076] Specifically, the buffer component 7 can be made of materials such as sponge pads. When the elastic materials such as sponge pads come into contact with the baffle component, they can undergo compression deformation, which can achieve kinetic energy buffering while limiting the rotation of the baffle component, thus helping to ensure the service life and reliability of the baffle component.

[0077] In some embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The baffle assembly is disposed as an upper baffle at the top inside the housing 5, and the baffle assembly is located between the heat exchanger 9 and the volute assembly 6.

[0078] When the air outlet of the volute assembly 6 faces the side air outlet 51 of the housing 5, the baffle assembly is in an extended state, and the bottom of the second baffle 3 is sealed against the second sealing abutment 61 on the volute assembly 6 through the first sealing abutment 33, which can separate the air outlet area and the return air area. When the impeller inside the volute assembly 6 rotates, it can blow the airflow towards the side air outlet 51, which can realize the side air outlet mode of the duct air conditioner. At this time, the baffle assembly and the volute assembly 6 are sealed against each other, which can ensure the sealing performance of the air outlet cavity and avoid air leakage.

[0079] When the ducted air conditioner needs to switch from side-discharge mode to bottom-discharge mode, it first makes way by rotating and extending the baffle assembly. The baffle assembly can rotate toward the side where the heat exchanger 9 is located, such as... Figure 4 As shown, it can also be rotated toward the side where the volute assembly 6 is located, such as... Figure 6 As shown, all of these can achieve avoidance of the volute assembly 6. The appropriate rotation direction can be selected according to the distance between the baffle assembly and the heat exchanger 9 and the volute assembly 6, the size of the heat exchanger 9 and the size of the volute assembly 6. No limitation is made here.

[0080] When the baffle assembly rotates toward the side where the volute assembly 6 is located, there needs to be a preset distance L (L ≥ the size of the baffle assembly after shrinkage) between the rotation axis of the first baffle 2 and the volute assembly 6, and L must be at least 30mm. Figure 6 As shown, this prevents interference between the baffle assembly and the volute assembly 6 during the rotation of the baffle assembly.

[0081] During the operation of the ducted air conditioner in the lower air outlet mode, because the baffle assembly is set in close contact with the inner wall of the housing 5, such as Figure 4 and Figure 6As shown, this design avoids obstructing the air intake at the side air outlet 51, prevents backflow of the intake airflow, and optimizes the air intake effect when the air is discharged downwards by rotating the volute assembly 6.

[0082] It should be noted that before the main structure of the baffle assembly (i.e., the first baffle 2 and the second baffle 3) rotates, in order to avoid interference between the end of the second baffle 3 (i.e. the side away from the hinge base 1) and other components in the housing 5, the baffle assembly can be retracted by sliding the second baffle 3 first, and then the first baffle 2 can be rotated; or the second baffle 3 can be slid simultaneously when the first baffle 2 is rotated.

[0083] Please see Figures 1 to 15 The third aspect of this application provides an air conditioning device, including the ducted air conditioner described in the above embodiments. By rotating the baffle assembly to make way, the volute assembly 6 can rotate inside the housing 5 to switch the air outlet direction without any interference risk. Since the size of the volute assembly 6 is not limited by the interference risk during rotation, it is no longer necessary to reduce its size to avoid the baffle. The size of the volute assembly 6 can be set large enough to output a larger air volume with the same motor power, or to consume less power with the same air volume. The overall energy efficiency ratio is substantially improved, which is beneficial to ensuring the working efficiency of the ducted air conditioner and the air conditioning equipment.

[0084] Please see Figures 1 to 15 In some embodiments of this application, the air outlet direction switching process of the above-mentioned ducted air conditioner is as follows: Step 1: The initial mode of the ducted air conditioner is side-discharge mode. The main structure of the baffle assembly is in an extended state. The first sealing abutment part 33 of the second baffle 3 and the second sealing abutment part 61 of the volute assembly 6 are in sealing contact. Figure 3 As shown.

[0085] Step 2: After receiving the instruction to switch from side air outlet mode to bottom air outlet mode, the second drive component 42 in the baffle assembly is activated first, driving the second baffle 3 to slide towards the hinge base 1, releasing the sealing contact between the first sealing contact part 33 and the second sealing contact part 61, and maintaining a safe distance between the first sealing contact part 33 and the second sealing contact part 61 to prevent the volute assembly 6 from interfering with the rotation of the second baffle 3 towards the side where the heat exchanger 9 is located.

[0086] Step 3: During the sliding of the second baffle 3, the first driving component 41 is activated, driving the first baffle 2 to rotate relative to the hinge base 1. During this process, the second baffle 3 slides relative to the first baffle 2 and rotates synchronously with the first baffle 2 until the second baffle 3 abuts against the stop part 22 on the first baffle 2 and the baffle assembly contacts the buffer assembly 7 on the inner wall of the housing 5. The first driving component 41 and the second driving component 42 then stop working.

[0087] Step 4: Rotate the base frame 8 to drive the volute assembly 6 to rotate, so that the air outlet of the volute assembly 6 is opposite to the lower air outlet 52 of the housing 5.
