Description

Technical Field

[0001] This invention relates to the field of air duct assembly technology, and more specifically, to an air duct assembly and an air conditioner having the same. Background Technology

[0002] Currently, existing air conditioning duct components have a single air outlet direction, typically only capable of vertical or horizontal airflow. This limited air outlet method greatly restricts the applicability of air conditioners in different usage scenarios, easily leading to uneven temperature distribution in the room, or causing users to feel too cold or experience physical discomfort.

[0003] However, to achieve multi-directional airflow, existing air conditioners typically employ complex damper structures or combinations of multiple baffles to control airflow direction. These designs not only increase manufacturing costs and assembly complexity but may also lead to increased airflow resistance within the ductwork, reducing overall energy efficiency. Furthermore, the complex damper structures and motor control programs make maintenance and troubleshooting difficult, impacting product market competitiveness and user satisfaction. Summary of the Invention

[0004] The main objective of this invention is to provide a duct assembly and an air conditioner having the same, so as to solve the technical problem of the single air outlet direction of the duct assembly in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a duct assembly is provided, comprising:

[0006] The volute assembly has a mounting cavity and multiple air vents connected to the mounting cavity, with the multiple air vents spaced apart along the periphery of the mounting cavity.

[0007] The volute tongue and the fan blade are included. The volute tongue includes a windproof part and a fan outlet part that are connected to each other. The windproof part forms a receiving cavity. The fan blade is movably disposed in the receiving cavity. The side of the fan outlet part away from the windproof part overlaps with the volute housing assembly. The fan outlet part forms a communication port that communicates with the receiving cavity. The volute tongue is rotatably disposed in the mounting cavity so that it can move to an air outlet position opposite to one of a plurality of fan outlets or to a blocking position opposite to a plurality of fan outlets.

[0008] Multiple first limiting parts are provided, each corresponding to a multiple air vent. The multiple first limiting parts are respectively located at the corresponding air vent. A second limiting part adapted to the first limiting part is provided on the side of the air vent away from the windproof part. When the volute tongue is in the air outlet position, the first limiting part and the second limiting part abut against each other.

[0009] Furthermore, there are multiple air outlet locations, each corresponding to a specific air vent; the air duct assembly also includes:

[0010] The driving component has a driving end that is movably set and connected to the worm tongue drive.

[0011] A position detection component is disposed at the air vent and facing the second limiting part. The position detection component is used to detect the distance between the second limiting part and any one of the first limiting parts.

[0012] Furthermore, the air duct assembly also includes:

[0013] The control unit, position detection unit, and drive unit are all connected to the control unit so that when the volute tongue moves from one of the blocking position or the air outlet position to the other of the air outlet positions, the rotational speed of the drive end is controlled according to the size of the distance between the first limit part and the second limit part corresponding to the other air outlet position detected by the position detection unit.

[0014] Furthermore, the air duct assembly also includes:

[0015] The first distance detection element and the second distance detection element are respectively located on the first air vent and the second air vent of the air vent. The first distance detection element and the second distance detection element are respectively arranged on both sides of the connecting opening and spaced apart along the periphery of the receiving cavity. The first distance detection element and the second distance detection element are respectively used to detect the distance between the first air vent and any one of the air vents and the distance between the second air vent and any one of the air vents.

[0016] The control unit, the first distance detection unit, the second distance detection unit, and the drive unit are all connected to the control unit. The control unit is used to control the rotation direction of the drive end according to the difference between the distance between the first air outlet detected by the first distance detection unit and the distance between the second air outlet detected by the second distance detection unit and the distance between the second air outlet detected by the second distance detection unit and the distance between the first air outlet and the second corresponding air outlet in the air outlet position when the volute tongue moves from one of the blocking position or the air outlet position to the other air outlet position.

[0017] Furthermore, the multiple first limiting parts can be movably arranged to extend to a position where each first limiting part protrudes from the outer edge of the volute assembly or to a position where each first limiting part avoids the second limiting part; the air duct assembly also includes a control component.

[0018] Among them, multiple first limiting parts and position detection elements are connected to the control element so that when the volute tongue moves from the blocking position to one of the air outlet positions, the corresponding first limiting part is controlled to be in the extended position or the avoidance position according to the distance between the first limiting part and the second limiting part corresponding to one of the air outlet positions detected by the position detection element.

[0019] Furthermore, the driving component is a drive motor, the driving end is a gear structure, and a rack portion is provided on the worm tongue. The rack portion extends along at least a portion of the periphery of the worm tongue and is used to mesh with the gear structure.

[0020] Furthermore, the windbreak has an arc-shaped structure; and / or,

[0021] The windbreak portion and the volute assembly are spaced apart. The air vent portion includes a first air vent portion and a second air vent portion arranged opposite each other, forming a communication opening between the first air vent portion and the second air vent portion. Both the first air vent portion and the second air vent portion are arc-shaped structures. The convex portion of the second air vent portion is disposed facing the concave portion of the first air vent portion. A second limiting portion is disposed on the first air vent portion; and / or

[0022] The air duct assembly also includes an elastic element, which is located on the side of the air outlet away from the windbreak and is used to contact the volute assembly.

[0023] Furthermore, the volute assembly includes:

[0024] The installation section and the air guide section are interconnected. The installation section forms an installation cavity, and the air guide section forms an air guide channel. The air guide channel is connected to the installation cavity through at least one of a plurality of air outlets. The cross-sectional area of ​​the air guide channel gradually increases along the extension direction from the side of the air guide channel near the installation section to the side of the air guide channel away from the installation section.

[0025] According to another aspect of the present invention, an air conditioner is provided, comprising: the air duct assembly provided above.

[0026] Furthermore, air conditioning also includes:

[0027] The outer casing has multiple air outlets, which are arranged one-to-one with the multiple air outlets of the air duct assembly.

[0028] An evaporator is disposed inside the housing and located on one side of the volute assembly of the air duct assembly. The receiving cavity of the volute tongue of the air duct assembly is used to access the evaporator and is disposed opposite to the evaporator. Both the evaporator and the volute tongue extend along the height direction of the housing.

[0029] Applying the technical solution of this invention, the volute tongue within the volute assembly is designed as a rotatable structure. The rotation of the volute tongue aligns the connecting opening with one of multiple air vents, thereby achieving airflow from multiple directions. This design breaks the limitation of traditional air conditioning duct assemblies with a single airflow direction, significantly improving the applicability and comfort of the air conditioner in different scenarios. This airflow direction switching via volute tongue rotation eliminates the need for additional damper structures or multiple baffle combinations, simplifying the duct assembly structure and reducing manufacturing costs and assembly difficulty. Simultaneously, the simplified design reduces airflow resistance within the duct, improving the overall energy efficiency of the air conditioner. Furthermore, due to the volute tongue rotation control mechanism, the duct assembly of this solution can quickly switch from one airflow direction to another, improving the air conditioner's response speed to changes in ambient temperature and enhancing the user experience. Rapid and precise airflow direction switching is particularly important for scenarios requiring rapid indoor temperature adjustment. In addition, compared to traditional multiple damper or baffle structures, airflow direction control via volute tongue rotation reduces contact and friction between mechanical parts, lowering operating noise and improving the air conditioner's quiet operation. Furthermore, the simplified structure reduces potential failure points and lowers maintenance costs and complexity. Simultaneously, a second limiting part is provided on the side of the volute tongue's air outlet furthest from the windbreak, which matches the first limiting part on the volute housing assembly corresponding to the air outlet. When the volute tongue is in the air outlet position, the first and second limiting parts abut against each other. This limiting design ensures precise positioning of the volute tongue when rotating to various air outlet positions, preventing excessive rotation and guaranteeing accurate air outlet direction. Furthermore, the abutment prevents airflow leakage from non-target air outlets during transitions, thereby improving the accuracy and stability of airflow control. Therefore, the technical solution of this invention solves the technical problem of the single air outlet direction in existing duct assemblies. Attached Figure Description

[0065] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0066] like Figures 1 to 4 As shown, Embodiment 1 of the present invention provides an air duct assembly, which includes a volute assembly 1, a volute tongue 2, and a fan blade 3. The volute assembly 1 has a mounting cavity 11 and a plurality of air outlets 12 communicating with the mounting cavity 11, and the plurality of air outlets 12 are spaced apart along the periphery of the mounting cavity 11. The volute tongue 2 includes a windproof part 21 and an air outlet part 22 connected to each other. The windproof part 21 forms a receiving cavity, and the fan blade 3 is movably disposed in the receiving cavity. The side of the air outlet part 22 away from the windproof part 21 overlaps with the volute assembly 1. The air outlet part 22 forms a connecting port 221 that communicates with the receiving cavity. The volute tongue 2 is rotatably disposed in the mounting cavity 11 so that the connecting port 221 is positioned opposite to one of the multiple air outlets 12 for air outlet or at least a portion of the windproof part 21 is positioned opposite to the multiple air outlets 12 for blocking. The air duct assembly also includes multiple first limiting parts 4, which are arranged one-to-one with the multiple air outlets 12. The multiple first limiting parts 4 are respectively disposed at the corresponding air outlets 12. The side of the air outlet part 22 away from the windproof part 21 is provided with a second limiting part 222 that is adapted to the first limiting part 4. When the volute tongue 2 is in the air outlet position, the first limiting part 4 and the second limiting part 222 abut against each other.

[0067] The air duct assembly provided in Embodiment 1 of this invention features a rotatable volute tongue 2 within the volute assembly 1. Rotation of the volute tongue 2 aligns the connecting port 221 with one of the multiple air outlets 12, enabling airflow from multiple directions. This design breaks the limitation of traditional air conditioning duct assemblies with a single airflow direction, significantly improving the applicability and comfort of the air conditioner in different scenarios. This airflow direction switching via the rotation of the volute tongue 2 eliminates the need for additional damper structures or combinations of multiple baffles, simplifying the duct assembly structure and reducing manufacturing costs and assembly difficulty. Simultaneously, the simplified design reduces airflow resistance within the duct, improving the overall energy efficiency of the air conditioner. Furthermore, due to the rotation control mechanism of the volute tongue 2, the duct assembly of this solution can quickly switch from one airflow direction to another, improving the air conditioner's response speed to changes in ambient temperature and enhancing the user experience. Rapid and precise airflow direction switching is particularly important for scenarios requiring rapid indoor temperature adjustment by the air conditioner. Furthermore, airflow direction control is achieved through the rotation of the volute tongue 2. Compared to traditional multiple damper or baffle structures, this reduces contact and friction between mechanical parts, lowers operating noise, and improves the quietness of the air conditioner. The simplified structure also reduces potential failure points, lowering maintenance costs and complexity. Simultaneously, a second limiting part 222 is provided on the side of the volute tongue 2's air outlet 22 away from the wind deflector 21, which is adapted to the first limiting part 4 on the volute housing assembly 1 corresponding to the air outlet 12. When the volute tongue 2 is in the air outlet position, the first limiting part 4 abuts against the second limiting part 222. This limiting design ensures accurate positioning of the volute tongue 2 when rotating to each air outlet position, preventing excessive rotation and guaranteeing an accurate air outlet direction. Furthermore, the abutment also prevents airflow leakage from non-target air outlets 61 during conversion, thereby improving the accuracy and stability of airflow control. Therefore, the duct assembly provided in this embodiment solves the technical problem of a single air outlet direction in existing duct assemblies.

[0068] Specifically, the plurality of air vents 12 include a first air vent 121, a second air vent 122, a third air vent 123, and a fourth air vent 124 evenly spaced along the periphery of the mounting cavity 11. The first air vent 121 and the third air vent 123 are arranged opposite each other, and the second air vent 122 and the fourth air vent 124 are arranged opposite each other. The air outlet positions include a first air outlet position in which the connecting port 221 is opposite to the first air vent 121, a second air outlet position in which the connecting port 221 is opposite to the second air vent 122, a third air outlet position in which the connecting port 221 is opposite to the third air vent 123, and a fourth air outlet position in which the connecting port 221 is opposite to the fourth air vent 124. Specifically, the first air vent 121 is positioned above the air duct assembly, the second air vent 122 is positioned to the left of the air duct assembly, the third air vent 123 is positioned below the air duct assembly, and the fourth air vent 124 is positioned to the right of the air duct assembly.

[0069] Specifically, blade 3 is a centrifugal fan blade.

[0070] Specifically, one of the first limiting part 4 and the second limiting part 222 is a limiting protrusion, and the other is a limiting groove. When the volute tongue 2 is in the air outlet position, the first limiting part 4 and the second limiting part 222 engage. With this structural arrangement, through the cooperation of the limiting protrusion and the limiting groove, the volute tongue 2 can achieve stable stopping when rotated to the preset air outlet position, ensuring the precise alignment of the connecting port 221 and the designated air outlet 12, and improving the accuracy of airflow direction control. The simple mechanical structure of the limiting protrusion and groove for positioning the volute tongue 2 simplifies the structure of the air duct assembly compared to a complex damper or baffle control mechanism, reducing manufacturing costs and the potential failure rate.

[0071] Specifically, there are multiple air outlet positions, each corresponding to a specific air vent 12. The duct assembly also includes a drive component 5 and a position detection component. The drive end 51 of the drive component 5 is movably disposed and drivenly connected to the volute 2. The position detection component is disposed at the air vent 22 and faces the second limiting part 222. The position detection component is used to detect the distance between the second limiting part 222 and any one of the first limiting parts 4. The drive end 51 of the drive component 5 is disposed within the mounting cavity 11. With this structural arrangement, the drive component 5 is drivenly connected to the volute 2, and combined with the use of the position detection component, enabling the volute 2 to quickly and accurately switch between multiple air outlet positions, improving the air conditioner's adaptability to different usage scenarios and the convenience of user operation. Through the connection between the position detection component and the control component, the duct assembly possesses intelligent control capabilities, automatically adjusting the airflow direction according to actual needs. Simultaneously, this mechanism also facilitates fault diagnosis and maintenance, reducing maintenance costs and difficulties.

[0072] Specifically, the duct assembly also includes a control unit, a position detection unit, and a drive unit 5, all connected to the control unit. When the volute 2 moves from one of the blocking or outlet positions to the other outlet position, the control unit adjusts the rotational speed of the drive end 51 based on the distance between the first limit part 4 and the second limit part 222 corresponding to the other outlet position detected by the position detection unit. With this configuration, the control unit can dynamically adjust the rotational speed of the drive end 51 based on real-time feedback from the position detection unit, ensuring a smooth transition of the volute 2 when switching to the next outlet position. This avoids sudden changes in airflow that may occur during rapid switching, improving the stability and comfort of the air conditioning operation. Adjusting the rotational speed of the volute 2 by controlling the rotational speed of the drive end 51 reduces energy consumption during airflow direction changes, especially by reducing the rotational speed when the volute 2 approaches the target outlet position, avoiding unnecessary energy waste and improving the overall energy efficiency of the air conditioning system.

[0073] Specifically, when the distance between the first limiting part 4 and the second limiting part 222 in another corresponding air outlet position is less than a preset distance, the rotation speed of the control drive end 51 decreases; when the distance between the first limiting part 4 and the second limiting part 222 in another corresponding air outlet position is 0, the rotation speed of the control drive end 51 is 0; when the distance between the first limiting part 4 and the second limiting part 222 in another corresponding air outlet position is greater than or equal to the preset distance, the rotation speed of the control drive end 51 remains unchanged. In this way, by adjusting the rotation speed of the drive end 51, the volute tongue 2 is ensured to decelerate when approaching the target air outlet position, avoiding over-positioning caused by high-speed rotation. When the volute tongue 2 is completely aligned with the target first limiting part 4, the rotation speed drops to zero, preventing excessive rotation of the volute tongue 2 and ensuring accurate positioning of the volute tongue 2 in different air outlet positions. By dynamically adjusting the rotation speed, the impact that the volute tongue 2 may experience during rapid positioning is reduced, the wear of the drive component 5 is reduced, thereby extending the service life of the duct assembly and reducing maintenance costs.

[0074] Specifically, the driving component 5 is a motor gear. When the air duct assembly needs to switch from the current air outlet position to another air outlet position, the power of the driving component 5 is increased so that the second limiting part 222 passes over the first limiting part 4 corresponding to the current air outlet position and avoids it. In this way, when it is necessary to switch from one air outlet position to another, by increasing the power of the driving component 5, the second limiting part 222 of the volute tongue 2 can easily pass over the first limiting part 4 corresponding to the current air outlet position, realizing a fast and smooth change of air direction.

[0075] Specifically, the duct assembly further includes a first distance detection element and a second distance detection element. The first distance detection element and the second distance detection element are respectively located on the first air outlet 223 and the second air outlet 224 of the air outlet 22. The first distance detection element and the second distance detection element are respectively arranged on both sides of the connecting opening 221 and spaced apart along the periphery of the receiving cavity. The first distance detection element and the second distance detection element are used to detect the distance between the first air outlet 223 and any one of the air outlets 12, and the distance between the second air outlet 224 and any one of the air outlets 12. The first distance detection element, the second distance detection element and the driving element 5 are all connected to the control element. The control element is used to control the rotation direction of the driving end 51 according to the difference between the distance between the first air outlet 223 and the other corresponding air outlet 12 in the air outlet position detected by the first distance detection element and the distance between the second air outlet 224 and the other corresponding air outlet 12 in the air outlet position detected by the second distance detection element when the volute tongue 2 moves from one of the blocking position or the air outlet position to the other air outlet position. With this configuration, the distances between the first air vent 223 and the second air vent 224 of the volute tongue 2 and the air vent 12 are detected by the first and second distance detectors, respectively. This enables real-time monitoring of the position of the volute tongue 2 from both sides, improving the accuracy and reliability of airflow direction control. Based on the distance difference provided by the first and second distance detectors, the controller intelligently adjusts the rotation direction of the drive end 51, facilitating the rotation of the volute tongue 2 from the shortest path to the target air outlet position and increasing the speed of airflow direction switching.

[0076] It should be noted that "the distance between the first air vent 223 and the other corresponding air vent 12 in the air outlet position" refers to the distance between the side of the first air vent 223 away from the windshield 21 and the center line of the other corresponding air vent 12 in the air outlet position along the periphery of the volute assembly 1. "The distance between the second air vent 224 and the other corresponding air vent 12 in the air outlet position" refers to the distance between the side of the second air vent 224 away from the windshield 21 and the center line of the other corresponding air vent 12 in the air outlet position along the periphery of the volute assembly 1.

[0077] Specifically, when the distance between the first air vent 223 detected by the first distance detector and another corresponding air vent 12 in the air outlet position is greater than the distance between the second air vent 224 detected by the second distance detector and another corresponding air vent 12 in the air outlet position (the difference is positive), the rotation direction of the control drive end 51 is the extension direction from the second air vent 224 to the other corresponding air vent 12 in the air outlet position; when the distance between the first air vent 223 detected by the first distance detector and another corresponding air vent 12 in the air outlet position is less than the distance between the second air vent 224 detected by the second distance detector... When the distance between the first air vent 223 and another corresponding air vent 12 in the air outlet position is negative, the rotation direction of the control drive end 51 is the extension direction from the first air vent 223 to the other corresponding air vent 12 in the air outlet position. When the distance between the first air vent 223 detected by the first distance detector and the other corresponding air vent 12 in the air outlet position is equal to the distance between the second air vent 224 detected by the second distance detector and the other corresponding air vent 12 in the air outlet position (the difference is 0), the rotation direction of the control drive end 51 remains unchanged, that is, it rotates in the direction of the previous rotation. In this way, under different conditions of the distance between the first air vent 223 and the second air vent 224 and the target air vent 12, the shorter or better rotation path can be automatically selected, avoiding unnecessary rotation angles and time, and improving the efficiency of the volute tongue 2 switching from one air outlet position to another. Selecting the optimal rotation direction not only shortens the switching time, but also reduces the number of times the volute tongue 2 contacts the first limiting part 4 during rotation, thereby reducing the mechanical stress inside the air duct and extending the service life of the air duct assembly.

[0078] Specifically, multiple first limiting parts 4 are movably configured to move to either an extended position where each first limiting part 4 protrudes beyond the outer edge of the volute assembly 1 or a clearance position where each first limiting part 4 avoids the second limiting part 222; the duct assembly also includes a control component. The multiple first limiting parts 4 and the position detection component are all connected to the control component to control the corresponding first limiting part 4 to either an extended position or a clearance position when the volute tongue 2 moves from the blocking position to one of the air outlet positions, based on the distance between the corresponding first limiting part 4 and the second limiting part 222 detected by the position detection component at one of the air outlet positions. This structural configuration, by making the first limiting parts 4 movably configured, allows them to extend to the outer edge of the volute assembly 1 when necessary, forming a more stable limiting effect, and when limiting is not required, they can be moved to a clearance position to ensure the free rotation of the volute tongue 2. This flexible limiting mechanism improves the operational flexibility of the duct assembly. The connection between the position detection component and the control component allows the control component to precisely control the extension or avoidance of the first limit part 4 based on the real-time distance information between the volute tongue 2 and the first limit part 4. This avoids accidental contact between the first limit part 4 and the volute tongue 2 at non-target positions, improves the accuracy and reliability of wind direction switching, reduces friction and collision during the rotation of the volute tongue 2, reduces the possibility of abnormal noise during operation, and also reduces malfunctions caused by improper contact between the first limit part 4 and the volute tongue 2, thereby improving the operational stability and durability of the air duct assembly.

[0079] It should be noted that the portion of the first limiting part 4 that protrudes from the outer edge of the volute assembly 1 is used to abut against the second limiting part 222.

[0080] Specifically, when the distance between the first limiting part 4 and the second limiting part 222 corresponding to one of the air outlet positions detected by the position detection element is less than a preset distance, the corresponding first limiting part 4 is controlled to be in the extended position; when the distance between the first limiting part 4 and the second limiting part 222 corresponding to one of the air outlet positions detected by the position detection element is greater than or equal to the preset distance, the corresponding first limiting part 4 is controlled to be in the avoidance position. With this structural arrangement, by dynamically adjusting the position of the first limiting part 4, it can quickly respond to changes in the position of the volute tongue 2, ensuring efficient response of the volute tongue 2 when changing airflow direction, shortening the airflow direction switching time, and improving the convenience of user operation and the flexibility of air conditioning operation.

[0081] Specifically, when the volute 2 moves from the blocking position to one of the air outlet positions, the first limiting part 4 corresponding to one of the air outlet positions is controlled to be in the extended position, while the other first limiting parts 4 are in the avoidance position. In this way, when the volute 2 moves from the blocking position to the designated air outlet position, the control component can ensure that the target first limiting part 4 is in the extended position, while keeping the other first limiting parts 4 in the avoidance position, avoiding accidental contact between the volute 2 and the non-target first limiting parts 4 during the switching process, and ensuring the accuracy and safety of the air direction switching.

[0082] Specifically, the driving component 5 is a drive motor, the driving end 51 is a gear structure, and the volute tongue 2 is provided with a rack portion 23. The rack portion 23 extends along at least a portion of the periphery of the volute tongue 2 and is used to mesh with the gear structure. In this way, by using the meshing of the motor gear with the rack portion 23 on the volute tongue 2, the precise and stable rotation of the volute tongue 2 can be achieved, improving the accuracy and stability of the volute tongue 2's movement and ensuring the accuracy and smoothness of airflow direction conversion. The precise matching of the gear and rack reduces mechanical wear during the rotation of the volute tongue 2, extends the service life of key components in the air duct assembly, reduces the long-term maintenance cost of the air conditioner, and improves the reliability and economy of the system.

[0083] Specifically, the windbreak 21 has an arc-shaped structure. The windbreak 21 is an arc-shaped structure adapted to the mounting cavity 11. With this structural arrangement, the windbreak 21 is designed as an arc shape, and its shape is adapted to the mounting cavity 11, which can effectively reduce wind resistance, make airflow smoother, improve the air handling efficiency of the air duct assembly, reduce the energy consumption required to drive the fan blades 3, and thus save energy.

[0084] Specifically, the wind deflector 21 is spaced apart from the volute assembly 1. The air vent 22 includes a first air vent 223 and a second air vent 224 arranged opposite to each other, forming a connecting opening 221 between the first air vent 223 and the second air vent 224. Both the first air vent 223 and the second air vent 224 are arc-shaped structures, with the convex portion of the second air vent 224 facing the concave portion of the first air vent 223. A second limiting portion 222 is provided on the first air vent 223. With this structural arrangement, the arc-shaped design of both the first air vent 223 and the second air vent 224 can smoothly guide the airflow direction, making the airflow more stable when passing through the connecting opening 221. This avoids sudden changes in airflow direction and possible noise during changes in direction, enhancing the smoothness and quietness of the air conditioning operation. The second limiting part 222 is set on the first air outlet part 223. This design ensures the precise fit between the first limiting part 4 and the first air outlet part 223, improves the positioning accuracy and stability when the air direction is switched, and avoids air leakage and air conditioning performance degradation caused by improper position of the limiting part.

[0085] Specifically, the duct assembly also includes an elastic element, which is located on the side of the air outlet 22 away from the windbreak 21 and is used to contact the volute assembly 1. This structural arrangement provides additional sealing force, ensuring that non-target air outlets 12 can be more tightly sealed when the volute tongue 2 rotates to different air outlet positions, reducing airflow leakage and improving the accuracy of airflow direction control. The elastic element also cushions the impact force when the volute tongue 2 contacts the volute assembly 1, reducing hard contact between components, lowering mechanical wear, extending the service life of the duct assembly, and reducing long-term maintenance costs.

[0086] In this embodiment, the volute assembly 1 includes an interconnected mounting portion 13 and an air guide portion 14. The mounting portion 13 forms a mounting cavity 11, and the air guide portion 14 forms an air guide channel. The air guide channel communicates with the mounting cavity 11 through at least one of a plurality of air outlets 12. Along the extension direction of the air guide channel from the side near the mounting portion 13 to the side away from the mounting portion 13, the cross-sectional area of ​​the air guide channel gradually increases. This helps to form a more ideal airflow distribution, enhances the airflow guidance, and makes the airflow more uniform when passing through the air guide channel, improving the comfort and efficiency of the air conditioning system. The gradually increasing cross-sectional area design of the air guide channel reduces the airflow resistance in the channel, reduces the power required to drive the fan blades 3, reduces energy consumption, and improves the overall energy efficiency of the air conditioning system.

[0087] Specifically, there are at least two air guide sections 14, which are located on both sides of the mounting section 13. This structural arrangement improves the overall structural stability of the air duct assembly, ensures the stability and safety of the air duct assembly when the high-speed fan blade 3 is running, reduces the vibration and noise of the air duct assembly, and improves the overall operating quality of the air conditioning system.

[0088] Specifically, the air duct assembly also includes a fan blade drive component 31, which is disposed on one side of the volute assembly 1. The fan blade drive end of the fan blade drive component 31 extends into the receiving cavity and is drivenly connected to the fan blade 3. The fan blade drive component 31 is a brushless motor.

[0089] like Figures 5 to 10 As shown, Embodiment 2 of the present invention provides an air conditioner, which includes the air duct assembly provided in Embodiment 1.

[0090] The air conditioner provided in Embodiment 2 of this invention features a rotatable volute tongue 2 within the volute assembly 1. Rotation of the volute tongue 2 aligns the connecting port 221 with one of the multiple air vents 12, enabling airflow from multiple directions. This design breaks the limitation of traditional air conditioning duct assemblies with a single airflow direction, significantly improving the applicability and comfort of the air conditioner in different scenarios. This airflow direction switching via the rotation of the volute tongue 2 eliminates the need for additional damper structures or combinations of multiple baffles, simplifying the duct assembly structure and reducing manufacturing costs and assembly difficulty. Simultaneously, the simplified design reduces airflow resistance within the duct, improving the overall energy efficiency of the air conditioner. Furthermore, due to the rotation control mechanism of the volute tongue 2, the duct assembly of this solution can quickly switch from one airflow direction to another, improving the air conditioner's response speed to changes in ambient temperature and enhancing the user experience. Rapid and precise airflow direction switching is particularly important for scenarios requiring rapid indoor temperature adjustment. Furthermore, by controlling the airflow direction through the rotation of the volute tongue 2, compared to traditional multiple damper or baffle structures, the contact and friction between mechanical parts are reduced, operating noise is lowered, and the quietness of the air conditioner is improved. In addition, the simplified structure reduces potential failure points, lowering maintenance costs and complexity. Simultaneously, a second limiting part 222 is provided on the side of the volute tongue 2's air outlet 22 away from the wind deflector 21, which is adapted to the first limiting part 4 on the volute housing assembly 1 corresponding to the air outlet 12. When the volute tongue 2 is in the air outlet position, the first limiting part 4 abuts against the second limiting part 222. This limiting design ensures the precise positioning of the volute tongue 2 when rotating to each air outlet position, avoiding excessive rotation and ensuring accurate airflow direction. Furthermore, the abutment also prevents airflow leakage from non-target air outlets 61 during conversion, thereby improving the accuracy and stability of airflow control. Therefore, the air conditioner provided in this embodiment can solve the technical problem of a single airflow direction in existing duct assemblies.

[0091] Specifically, the air conditioner also includes a housing 6 and an evaporator 7. The housing 6 has multiple air outlets 61, each corresponding to a specific air outlet 12 of the duct assembly. The evaporator 7 is located inside the housing 6 and on one side of the volute assembly 1 of the duct assembly. The receiving cavity of the volute tongue 2 of the duct assembly provides access to the evaporator 7 and is positioned opposite to it. Both the evaporator 7 and the volute tongue 2 extend along the height of the housing 6. This structural arrangement, with the volute tongue 2 of the duct assembly opposite to the evaporator 7 and both extending along the height of the housing 6, ensures efficient airflow between the duct and the evaporator 7. The receiving cavity of the volute tongue 2 directly connects to the evaporator 7, reducing airflow loss during transmission and improving the cooling or heating efficiency of the air conditioning system. This design also helps optimize the internal space of the air conditioner, providing more possibilities for the arrangement of other key components such as fans and motors, enhancing the overall design flexibility and performance of the air conditioner.

[0092] Specifically, the multiple air outlets 61 include an upper air outlet 611 corresponding to the first air outlet 121, a lower air outlet 612 corresponding to the third air outlet 123, a left air outlet 613 corresponding to the second air outlet 122, and a right air outlet 614 corresponding to the fourth air outlet 124.

[0093] Specifically, the air conditioner also includes an air inlet panel 62, which supports the entire air conditioner. The evaporator 7 is located on one side of the air inlet grille of the air inlet panel 62 and is fixedly mounted on it. The volute assembly 1 includes a volute cover 15, which is located on one side of the evaporator 7 and is fixedly mounted on the air inlet panel 62. The volute cover 15 and the volute component 16 cooperate to form an air duct. The air conditioner also includes a left side panel 63, located on the left side of the air conditioner and fixedly mounted on the air inlet panel 62, with a left air outlet 613 on it. The air conditioner also includes a chassis 66, located at the bottom of the air conditioner, serving as a support and also for decoration. The air conditioner also includes a lower air outlet 67, located below the air duct and fixedly mounted on the air inlet panel 62, forming the lower air outlet 612. The air conditioner also includes a front panel 65, located at the front of the air conditioner and mounted on the air inlet panel 62. The air conditioner also includes a right side panel 64, located on the right side of the air conditioner, on which a right air outlet 614 is provided, serving both decorative and air outlet functions. The air conditioner also includes an upper air outlet 68, which has an upper air outlet channel and is installed on the air inlet panel 62. An air guide plate is provided on the upper air outlet 68 to guide airflow. The air conditioner also includes a top cover 69, located at the top of the air conditioner and installed on the air inlet panel 62 and the front panel 65, on which an upper air outlet 611 is provided.

[0094] Figure 7This diagram illustrates the structure of the air conditioner when the duct assembly is in the first air outlet position. When the air conditioner needs to vent upwards, simply press the "upward air outlet" button. Because the volute tongue 2 is blocked by the flange (equivalent to the first limiting part 4), the motor gear needs to increase its power to overcome the preload of the flange during startup. When the second limiting part 222 of the volute tongue 2 moves close to the first air outlet 121, the power of the motor gear decreases, the speed slows down, and the second limiting part 222 of the volute tongue 2 is blocked and limited by the flange. The position sensor (equivalent to the position detection element) senses that the second limiting part 222 is in contact with the first limiting part 4, and the motor gear stops. When the rotation stops, the volute tongue 2 is precisely positioned at the first air outlet 121. The opening of the volute tongue (equivalent to the connecting port 221) is aligned with the first air outlet 121. The three air outlets on the left, right, and bottom of the air duct are closed. At this time, the air duct forms a one-way upward ventilation channel. The fan motor (equivalent to the fan drive component 31) starts, and the air conditioner can only blow air upward. The process does not require a baffle structure to change the air direction. The air direction can be changed simply by rotating the volute tongue 2. It is a one-step process with a fast reversal speed. The air conditioner blows air upward, providing a shower-like airflow, resulting in a good user experience and high comfort.

[0095] Figure 8 This diagram illustrates the structure of the air conditioner when the duct assembly is in the second air outlet position. When the air conditioner needs to outlet air to the left, simply press the "left air outlet" button. Since the volute tongue 2 is blocked by the flange (equivalent to the first limiting part 4), the motor gear needs to increase its power to overcome the preload of the flange during startup. When the second limiting part 222 of the volute tongue 2 moves close to the second air outlet 122, the power of the motor gear decreases, the speed slows down, and the second limiting part 222 of the volute tongue 2 is blocked and limited by the flange. The position sensor (equivalent to the position detection element) senses that the second limiting part 222 is in contact with the first limiting part 4, and the motor gear stops rotating. When the volute tongue 2 is in motion, it is precisely positioned at the second air outlet 122. The opening of the volute tongue (equivalent to the connecting port 221) is aligned with the second air outlet 122. The three air outlets at the bottom, right, and top of the air duct are closed. At this time, the air duct forms a one-way ventilation channel to the left. The fan motor (equivalent to the fan drive component 31) is started, and the air conditioner can only blow air to the left. The process does not require the baffle structure to change the air direction. The air direction can be changed simply by rotating the volute tongue 2. It is a one-step process with a fast reversal speed. The left air outlet 613 is located on the left side of the air conditioner, so the air conditioner air does not blow directly on people, resulting in high comfort.

[0096] Figure 9This diagram illustrates the structure of the air conditioner when the duct assembly is in the third air outlet position. When the air conditioner needs to outlet downwards, simply press the "downward air outlet" button. Since the volute tongue 2 is blocked by the flange (equivalent to the first limiting part 4), the motor gear needs to increase its power to overcome the preload force of the flange during startup. When the second limiting part 222 of the volute tongue 2 moves close to the third air outlet 123, the motor gear power decreases, and the speed slows down. The second limiting part 222 of the volute tongue 2 is blocked and limited by the flange. The position sensor (equivalent to the position detection element) senses that the second limiting part 222 is in contact with the first limiting part 4, and the motor gear... When the wheel stops rotating, the volute tongue 2 is precisely positioned at the third air outlet 123. The opening of the volute tongue (equivalent to the connecting port 221) is aligned with the third air outlet 123. The three air outlets on the left, right, and top of the air duct are closed. At this time, the air duct forms a one-way downward ventilation channel. The fan motor (equivalent to the fan drive component 31) starts, and the air conditioner can only blow air downwards. The process does not require a baffle structure to change the air direction. The air direction can be changed simply by rotating the volute tongue 2. It is a one-step process with a fast reversal speed. The downward air outlet generally blows warm air, which starts from the feet and provides high comfort.

[0097] Figure 10 This diagram illustrates the structure of the air conditioner when the duct assembly is in the fourth air outlet position. When the air conditioner needs to outlet air to the right, simply press the "Right Air Outlet" button. Since the volute tongue 2 is blocked by the flange (equivalent to the first limiting part 4), the motor gear needs to increase its power to overcome the preload force of the flange during startup. When the second limiting part 222 of the volute tongue 2 moves close to the fourth air outlet 124, the power of the motor gear decreases, the speed slows down, and the second limiting part 222 of the volute tongue 2 is blocked and limited by the flange. The position sensor (equivalent to the position detection element) senses that the second limiting part 222 is in contact with the first limiting part 4, and the motor gear stops rotating. When the volute tongue 2 is in motion, it is precisely positioned at the fourth air outlet 124. The opening of the volute tongue (equivalent to the connecting port 221) is aligned with the fourth air outlet 124. The three air outlets at the bottom, left, and top of the air duct are closed. At this time, the air duct forms a one-way ventilation channel to the right. The fan motor (equivalent to the fan drive component 31) is started, and the air conditioner can only blow air to the right. The process does not require a baffle structure to change the air direction. The air direction can be changed simply by rotating the volute tongue 2. It is a one-step process with a fast reversal speed. The right air outlet 614 is located on the right side of the air conditioner, so the air conditioner air does not blow directly on people, resulting in high comfort.

[0098] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: the air duct has multiple air outlets and multiple air outlet directions, breaking the traditional air conditioning method of only being able to outlet air up and down or left and right. The air duct structure is simple, requiring no additional structure or multiple baffles and dampers, only a circular air cavity and a volute tongue are needed for cooperation, and the control method is simple; the volute tongue not only has the function of guiding the airflow, but also has the functions of blocking wind, sealing, and reversing. Because the circumference of the volute tongue is equipped with a rack and pinion structure that meshes with the motor gears, the volute tongue can rotate, allowing the air outlet to change direction 360 degrees within the duct cavity, thus enabling airflow in four different directions: up, down, left, and right. The volute tongue's air outlet portion seals against the inside of the duct's circular cavity, creating a baffle to prevent air leakage and ensure the stability of the airflow direction. The air conditioner's reversing speed is fast, and the reversing program is simple to design; different airflow directions can be switched simply by controlling the motor's forward and reverse rotation. The airflow direction stability is high because each air outlet has a flange that blocks the volute tongue when it reaches the outlet, preventing further rotation. Combined with a position sensor, this achieves precise positioning. When the volute tongue needs to rotate, the presence of the small flange provides preload, requiring the motor to increase its power to overcome the flange, thus improving the accuracy of the volute tongue's stopping position.
