Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, specifically to an air outlet device and an air conditioner. Background Technology

[0002] In related technologies, the current air outlet devices have a single air outlet method, which is not conducive to improving the user experience. Utility Model Content

[0003] The purpose of this disclosure is to provide an air outlet device and an air conditioner that can achieve multiple air outlet modes, which is suitable for improving user experience.

[0004] To achieve the above objectives, this disclosure provides an air outlet device, comprising: a housing having an air inlet; and a dual-outlet fan disposed within the housing and including a volute, the volute including a first air outlet and a second air outlet disposed within the housing, the volute having an opening and closing mechanism for causing airflow to be blown out from the first air outlet or from the second air outlet; the air outlet device having a first air outlet mode or a second air outlet mode, in the first air outlet mode, the opening and closing mechanism causing airflow to be blown out from the first air outlet; in the second air outlet mode, the opening and closing mechanism causing airflow to be blown out from the second air outlet.

[0005] Through the above technical solution, airflow enters the housing through the air inlet. In the first air outlet mode, the rotation of the dual-outlet fan drives the airflow inside the housing into the volute, and the opening and closing mechanism allows the airflow to be blown out through the first air outlet. In the second air outlet mode, the rotation of the dual-outlet fan drives the airflow inside the housing into the volute, and the opening and closing mechanism allows the airflow to be blown out through the second air outlet. Therefore, airflow in both the first and second air outlet modes can enter through the air inlet, allowing the airflow entering the volute to exit through both the first and second air outlets. This provides different air outlet paths for the airflow entering the air outlet device, achieving different air outlet methods. This simplifies the structure of the air outlet device, reduces production costs, and allows for customization to meet different usage scenarios according to user needs.

[0006] In some possible implementations, the dual-outlet fan rotates in the same direction in both the first and second air outlet modes. This allows for unidirectional rotation of the dual-outlet fan, enabling both the first and second air outlet modes, while simplifying the control logic.

[0007] In some possible implementations, the volute includes a first air duct and a second air duct, the first air duct having a first air outlet and the second air duct having a second air outlet. This allows airflow to be directed to either the first or second air duct depending on their orientation, thereby enabling control over whether the airflow exits through the first or second air outlet.

[0008] In some possible implementations, the opening and closing mechanism includes an opening and closing element that closes the other of the first and second air outlets when one of them is opened. This design of the opening and closing element prevents airflow from being split or opposing within the volute when the first and second air outlets are open simultaneously, thus reducing airflow efficiency and helping to ensure airflow efficiency and stability in both the first and second airflow modes.

[0009] In some possible implementations, the first air duct and the second air duct are connected by an air outlet. The opening and closing member has a first position and a second position. In the first position, the opening and closing member opens the first air outlet and closes the air outlet to close the second air outlet. In the second position, the opening and closing member closes the first air outlet and opens the air outlet to open the second air outlet. Thus, when the opening and closing member is in the first position, the airflow entering the volute can be blown through the first air duct to the first air outlet for discharge. When the opening and closing member is in the second position, the airflow entering the volute can flow through the second air duct to the second air outlet for discharge.

[0010] In some possible implementations, the opening / closing element is rotatably disposed at the end of the air vent near the first air outlet. In this way, only a single opening / closing element is needed; by rotating the element, the first and second air outlets can be opened and closed, which helps to shorten the switching path of the opening / closing element and improve the switching efficiency between the first and second air outlet modes.

[0011] In some possible implementations, the opening and closing mechanism includes a drive member disposed within the volute housing and used to drive the opening and closing member to move. This allows the drive member to be integrated within the volute housing, reducing its footprint and optimizing the internal layout of the air outlet device. Furthermore, the drive member can be positioned close to the opening and closing member to shorten the transmission distance.

[0012] In some possible implementations, the first air duct is constructed as a front air duct extending forward and backward, with the first air outlet for forward airflow; and / or, the second air duct is constructed as a lower air duct extending vertically, with the second air outlet for downward airflow. Thus, in the first airflow mode, the airflow can be guided forward through the first air duct so that the first air outlet can directionally deliver the airflow forward. In the second airflow mode, after the airflow in the second cavity enters the dual-outlet fan, it can be guided downward through the second air duct so that the airflow can be directionally delivered downward through the second air outlet.

[0013] In some possible implementations, the housing contains at least two dual-outlet fans, wherein two adjacent dual-outlet fans are driven by the same motor, and / or, two adjacent opening and closing mechanisms move synchronously. This allows at least two dual-outlet fans to work collaboratively, increasing the intake and exhaust airflow, expanding the air supply coverage area, and thereby improving the airflow circulation efficiency of the exhaust device. Synchronized movement of the two adjacent opening and closing mechanisms avoids mutual interference or collision of airflows when the two adjacent dual-outlet fans exit from the first and second exhaust outlets respectively, preventing airflow loss or noise generation if the two opening and closing mechanisms move asynchronously.

[0014] In some possible implementations, the dual-outlet fan is constructed as a centrifugal fan. This centrifugal fan enables axial air intake and radial air exhaust, facilitating the adaptation of the front and lower air outlets on the radial side of the dual-outlet fan for air distribution.

[0015] In some possible implementations, at least two of the dual-outlet fans are arranged at intervals along the axial direction of the motor, with the air inlet located between two adjacent dual-outlet fans, and / or, the air inlet is located on the outer side of the volute along the axial direction. This helps to ensure the air outlet coverage area and allows the airflow to be evenly distributed in a predetermined direction, ensuring effective airflow circulation. The airflow entering the volute through the air inlet can simultaneously supply two adjacent dual-outlet fans, ensuring uniform diffusion of airflow within the volute and facilitating the circulation of airflow in the outer area of ​​the volute's side, thus improving circulation efficiency.

[0016] In some possible implementations, two adjacent opening / closing elements are driven by the same drive shaft, which is positioned between two adjacent volutes. This ensures synchronized movement of the two adjacent opening / closing mechanisms by rotating the drive shaft. Simultaneously, it shortens the length of the drive shaft connecting the two opening / closing elements and makes full use of the space between the two adjacent volutes.

[0017] In some possible implementations, the drive shaft is drive-connected to a drive member, which is located on the side of one of the volutes away from the other. In this way, by arranging the drive member on one side, the drive member can be directly drive-connected to the drive shaft to drive the two adjacent opening and closing parts to move synchronously, simplifying the power transmission path.

[0018] In some possible implementations, the first air outlet is configured as a front air outlet, and the housing includes a front plate, with the front air outlet located at the air outlet of the front plate. In this way, the airflow delivered through the first air outlet can be directly blown out of the volute through the front air outlet, thus achieving front airflow through the first air outlet.

[0019] In some possible implementations, the second air outlet is configured as a bottom air outlet, located on the bottom plate of the housing. In this way, since the bottom plate is located at the bottom of the housing, the airflow delivered through the bottom air outlet can be directly guided downwards to achieve downward airflow, reducing upward airflow loss and thus lowering energy consumption.

[0020] In some possible implementations, the air outlet device includes a heat exchanger disposed within the housing and positioned between the dual-outlet fan and the air inlet. This allows the airflow entering the housing from the air inlet to first pass through the heat exchanger for heat exchange, achieving heating or cooling, before entering the dual-outlet fan for delivery. This avoids the situation where airflow is directly discharged without heat exchange, thus improving energy efficiency.

[0021] In some possible implementations, the housing includes a rear panel, and the air inlet is located on the rear panel. This allows airflow to enter the interior from the rear side of the housing, avoiding interference with the airflow from the front or lower air outlet, which would affect the airflow volume and efficiency, and thus help ensure airflow stability.

[0022] In some possible implementations, the dual-outlet fan is constructed as a centrifugal fan or a cross-flow fan, with an inlet on the fan casing that communicates with the air inlet. This facilitates adaptation to different user needs and expands the application range.

[0023] According to a second aspect of this disclosure, an air conditioner is provided, including the air outlet device as described above.

[0024] In some possible implementations, the air conditioner is configured as a ducted unit. This allows for both front and bottom airflow when the ducted unit is installed at the ceiling of the room, enhancing the user experience.

[0025] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

Furthermore, the use of terms such as "first" and "second" is intended to distinguish different components and does not imply sequentiality or importance. Additionally, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the scope of this disclosure.

[0030] According to a specific embodiment of this disclosure, refer to Figures 1 to 10 As shown, an air outlet device is provided, including: a housing 1 with an air inlet 11; and a dual-outlet fan 2 disposed within the housing 1, including a volute 21. The volute 21 includes a first air outlet 211 and a second air outlet 212 disposed within the housing 1. An opening and closing mechanism 22 is provided within the volute 21, which is used to allow airflow to be blown out from the first air outlet 211 or from the second air outlet 212. The air outlet device has a first air outlet mode or a second air outlet mode. In the first air outlet mode, the opening and closing mechanism 22 allows airflow to be blown out from the first air outlet 211; in the second air outlet mode, the opening and closing mechanism 22 allows airflow to be blown out from the second air outlet 212.

[0031] Through the above technical solution, airflow enters the housing 1 through the air inlet 11. In the first air outlet mode, the rotation of the dual-outlet fan 2 drives the airflow inside the housing 1 into the volute 21, and the opening and closing mechanism 22 causes the airflow to be blown out from the first air outlet 211. In the second air outlet mode, the rotation of the dual-outlet fan 2 drives the airflow inside the housing 1 into the volute 21, and the opening and closing mechanism 22 causes the airflow to be blown out from the second air outlet 212. Thus, the airflow in both the first and second air outlet modes can enter through the air inlet 11, allowing the airflow entering the volute 21 to be discharged through both the first air outlet 211 and the second air outlet 212. This allows the airflow entering the air outlet device to have different discharge paths and achieve different discharge methods, thereby simplifying the structure of the air outlet device, reducing production costs, and enabling it to meet different usage scenarios according to user needs.

[0032] In some embodiments of this disclosure, reference is made to Figure 7 and Figure 9 As shown, in both the first and second air outlet modes, the dual-outlet fan 2 rotates in the same direction. This ensures that the air volume is essentially the same in both modes. Driving the dual-outlet fan 2 to rotate unidirectionally allows air to exit from both the first outlet 211 and the second outlet 212, thus enabling both air outlet modes and simplifying the control logic. This avoids the wear and tear caused by the reverse rotation of the dual-outlet fan 2 in both the first and second air outlet modes, which would otherwise require the fan to be in either forward or reverse rotation. Therefore, it helps reduce wear on the motor 4, extending its service life, and also reduces the number of internal components, simplifying the internal structure.

[0033] In some embodiments of this disclosure, reference is made to Figure 5 , Figure 7 and Figure 9 As shown, the volute 21 includes a first air duct 213 and a second air duct 214. The first air duct 213 has a first air outlet 211, and the second air duct 214 has a second air outlet 212. Thus, when the dual-outlet fan 2 drives airflow into the volute 21, the airflow is guided towards the first air outlet 211 by introducing air into the first air duct 213, resulting in airflow exiting from the first air outlet 211. Similarly, the airflow is guided towards the second air outlet 212 by introducing air into the second air duct 214. Therefore, by adjusting the direction of the first air duct 213 and the second air duct 214, the airflow can be directed to either the first air duct 213 or the second air duct 214, thereby controlling whether the airflow exits from the first air outlet 211 or the second air outlet 212.

[0034] In some embodiments of this disclosure, reference is made to Figures 5 to 9As shown, the opening and closing mechanism 22 includes an opening and closing element 221, which is used to close the other of the first air outlet 211 and the second air outlet 212 when one of them is opened. In this way, the opening and closing element 221 can selectively open the first air outlet 211 and the second air outlet 212, simplifying the structure of the opening and closing mechanism 22. Furthermore, it facilitates opening the first air outlet 211 and closing the second air outlet 212 in the first air outlet mode, preventing airflow leakage from the second air outlet 212 and reducing the air outlet efficiency of the first air outlet mode. In the second air outlet mode, it can open the second air outlet 212 and close the first air outlet 211, preventing airflow leakage from the first air outlet 211 and reducing the air outlet efficiency of the second air outlet mode. Therefore, the opening and closing component 221 can prevent the airflow from being split or collided in the volute 21 when the first air outlet 211 and the second air outlet 212 are opened at the same time, thus reducing the air outlet efficiency. This helps to ensure the air outlet efficiency and air outlet stability in the first air outlet mode and the second air outlet mode.

[0035] Of course, in other embodiments, the opening and closing mechanism 22 may include a first switch and a second switch. The first switch is used to open and close the first air outlet 211, and the second switch is used to open and close the second air outlet 212. In this way, the first air outlet 211 and the second air outlet 212 can be opened and closed separately.

[0036] In some embodiments of this disclosure, reference is made to Figures 5 to 9 As shown, the first air duct 213 and the second air duct 214 are connected by an air outlet 215. The opening and closing member 221 has a first position and a second position. In the first position, the opening and closing member 221 opens the first air outlet 211 and closes the air outlet 215 to close the second air outlet 212. In this way, when the opening and closing member 221 is in the first position, the airflow entering the volute 21 can be blown to the first air outlet 211 through the first air duct 213 to be discharged through the first air outlet 211. At the same time, closing the air outlet 215 can prevent the airflow from being guided through the second air duct 214 and blown out through the second air outlet 212, which would cause diversion and affect the airflow efficiency. Furthermore, by closing the air outlet 215, the first air duct 213 and the second air duct 214 can be isolated to prevent the airflow from continuing to flow to the second air duct 214, which is beneficial to improving the airflow efficiency.

[0037] In the second position, the opening / closing element 221 closes the first air outlet 211 and opens the air outlet 215 to open the second air outlet 212. Thus, when the opening / closing element 221 is in the second position, the airflow entering the volute 21 can enter the second air duct 214 via the first air duct 213, and flow through the second air duct 214 to the second air outlet 212 for discharge. Because the opening / closing element 221 closes the first air outlet 211, it prevents airflow from being blown out of the first air outlet 211, thus avoiding diversion and affecting airflow efficiency.

[0038] In some embodiments of this disclosure, reference is made to Figures 5 to 9 As shown, the opening / closing element 221 is rotatably disposed at the end of the air vent 215 near the first air outlet 211. Thus, when the opening / closing element 221 is rotated to the first position, it covers the first air outlet 211 to close it; when rotated to the second position, it covers the air vent 215 to prevent airflow into the second air duct 214, thereby closing the second air outlet 212. Therefore, only a single opening / closing element 221 is needed; by rotating the opening / closing element 221, the opening and closing of the first air outlet 211 and the second air outlet 212 can be achieved, which helps to shorten the switching path of the opening / closing element 221 and improve the switching efficiency between the first and second air outlet modes.

[0039] In some embodiments of this disclosure, reference is made to Figure 4 As shown, the opening and closing mechanism 22 includes a driving member 222, which is disposed in the volute 21 and used to drive the opening and closing member 221 to move. In this way, the driving member 222 can be integrated into the volute 21, reducing the space occupied within the housing 1 and facilitating the optimization of the internal layout of the air outlet device. Simultaneously, the driving member 222 can be positioned close to the opening and closing member 221 to shorten the transmission distance, reduce the response time when the opening and closing member 221 opens or closes the first air outlet 211 or the second air outlet 212, and improve transmission efficiency while reducing power loss.

[0040] In some embodiments of this disclosure, reference is made to Figures 5 to 9 As shown, the first air duct 213 is constructed as a front air duct extending forward and backward, and the first air outlet 211 is used for forward airflow. In this way, in the first airflow mode, after the airflow enters the dual-outlet fan 2, it can be guided forward through the first air duct 213 so that the first air outlet 211 can direct the airflow forward. Thus, forward airflow can be achieved in the first airflow mode, which can meet the user's need for forward airflow and avoid the airflow blowing directly on the human body, causing discomfort.

[0041] The second air duct 214 is constructed as a vertically extending downward air duct, and the second air outlet 212 is used for downward airflow. Thus, in the second airflow mode, after the airflow in the second cavity enters the dual-outlet fan 2, it can be guided downward through the second air duct 214 to be directionally delivered downwards through the second air outlet 212. This achieves downward airflow in the second airflow mode, thus meeting the user's need for downward airflow and preventing airflow from stagnating at the top and failing to circulate fully downwards. Therefore, the airflow entering the volute 21 can be guided by the first air duct 213 or the second air duct 214 to achieve airflow in different directions, adapting to the user's needs for different airflow directions in different scenarios and improving applicability.

[0042] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 4 and Figure 3 As shown, the housing 1 contains at least two dual-outlet fans 2, with adjacent dual-outlet fans 2 driven by the same motor 4. When at least two dual-outlet fans 2 are driven by the same motor 4, they can work collaboratively to increase the intake and exhaust air volume, expand the air supply coverage area, and thus improve the airflow circulation efficiency of the air outlet device, which is beneficial for adapting to large space requirements. Furthermore, it ensures that the rotational speeds of adjacent dual-outlet fans 2 are consistent, avoiding mutual airflow interference, which helps ensure the reliability of the air outlet device's operation and reduces the number of motors 4, thereby reducing the area occupied by the motors 4 and achieving a compact design of the air outlet device, which helps reduce production costs. Of course, the at least two dual-outlet fans 2 can each be driven by a single motor 4; this disclosure does not impose any limitation on this.

[0043] Among them, the rotating shaft 41 of the motor 4 can be coaxially set and connected with the impellers of the two adjacent double-outlet fans 2 so that the rotating shaft 41 can rotate and drive the two adjacent double-outlet fans 2 to run synchronously.

[0044] In some embodiments of this disclosure, reference is made to Figure 3 and Figure 4 As shown, the two adjacent opening and closing mechanisms 22 move synchronously. This allows both adjacent dual-outlet fans 2 to be in the first air outlet mode, opening the first air outlet 211 and closing the second air outlet 212, ensuring that the airflow from both fans can exit through the first air outlet 211, thus guaranteeing the airflow volume of the first air outlet mode. Alternatively, both fans can be in the second air outlet mode, opening the second air outlet 212 and closing the first air outlet 211, ensuring that the airflow from both fans can exit through the second air outlet 212, thus guaranteeing the airflow volume of the second air outlet mode. This avoids situations where the two opening and closing mechanisms 22 move asynchronously, causing airflow interference or collision when the two fans 2 exit through the first and second air outlets 211 respectively, resulting in airflow loss or noise, affecting airflow efficiency and user experience.

[0045] In some embodiments of this disclosure, reference is made to Figures 1 to 9 As shown, the dual-outlet fan 2 is constructed as a centrifugal fan. This centrifugal fan enables axial air intake and radial air exhaust, facilitating airflow from the front and lower air outlets 215 on the radial side of the dual-outlet fan 2. Furthermore, the centrifugal fan has higher static pressure, which helps overcome the resistance caused by duct extension, thus ensuring sufficient air delivery distance and coverage, and reducing the occurrence of reduced airflow due to ductwork design.

[0046] In some embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, at least two dual-outlet fans 2 are arranged at intervals along the axial direction of the motor 4. This arrangement of at least two dual-outlet fans 2 helps to ensure and increase the airflow volume and improve airflow efficiency. The axial spacing of the fans also helps to ensure the airflow coverage area and allows the airflow to be evenly distributed in a preset direction, ensuring effective airflow circulation. An air inlet 11 is located between two adjacent dual-outlet fans 2. This air inlet 11 between two adjacent dual-outlet fans 2 provides a shared airflow channel for both fans, allowing the airflow entering the volute 21 through the air inlet 11 to simultaneously supply both fans. This ensures that the airflow is evenly diffused within the volute 21, guaranteeing sufficient airflow for both fans and preventing localized insufficient airflow. The air inlet 11 is located axially on the outer side of the volute 21. In this way, the air inlet 11 located on the outside of the volute 21 can cooperate with the air inlet 11 between two adjacent dual-air-mouth fans 2, so that airflow can enter from both sides of the volute 21 to ensure air intake efficiency, and also to help drive the airflow in the external area on the side of the volute 21 to participate in circulation and improve circulation efficiency.

[0047] In some embodiments of this disclosure, reference is made to Figure 3 and Figure 4 As shown, two adjacent opening / closing components 221 are driven by the same drive shaft, which is located between two adjacent volutes 21. By rotating the drive shaft, the first air outlets 211 of the two adjacent dual-outlet fans 2 can be opened and closed synchronously, or the second air outlets 212 of the two adjacent dual-outlet fans 2 can be opened and closed synchronously, achieving synchronous movement of the two adjacent opening / closing mechanisms 22. This ensures that the airflow direction delivered by the two adjacent dual-outlet fans 2 remains consistent, and reduces the impact on air delivery efficiency caused by delays or deviations when the drive shafts of the two adjacent opening / closing components 221 are driven separately, thus helping to ensure the stability of the airflow. Simultaneously, the drive shaft is located between two adjacent volutes 21 to shorten the length of the drive shaft connecting the two opening / closing components 221, and to fully utilize the space between the two adjacent volutes 21, optimizing the internal space utilization of the air outlet device, facilitating a compact design, and avoiding interference with the airflow path of the dual-outlet fans 2, ensuring the stability of the airflow.

[0048] In some embodiments of this disclosure, reference is made to Figure 4As shown, the drive shaft is connected to the drive component 222, which is located on the side of one of the volutes 21 away from the other. By setting the drive component 222 on one side, it can be directly connected to the drive shaft to drive the two adjacent opening / closing components 221 to move synchronously. The power transmission path is simple. Compared to setting the drive component 222 on both sides of the two housings, this reduces transmission complexity, improves power transmission efficiency, and ensures synchronous movement of the two adjacent opening / closing components 221. Simultaneously, this arrangement facilitates assembly of the drive component 222, avoiding the situation where limited operating space hinders assembly efficiency when it is located between the two volutes 21. It also facilitates maintenance and repair, improving operational efficiency.

[0049] In some embodiments of this disclosure, reference is made to Figures 3 to 9 As shown, the first air outlet 211 is configured as a front air outlet 215. The housing 1 includes a front plate 12, and the front air outlet 215 is located at the air outlet 215 of the front plate 12. In this way, the airflow delivered through the first air outlet 211 can be directly blown out of the housing 1 through the front air outlet 215. That is, the first air outlet 211 is also used as the air outlet 215 of the air outlet device to achieve front airflow, meet user needs, avoid airflow blowing directly onto the human body and causing discomfort, and shorten the airflow path delivered through the first air duct 213, reducing airflow loss. Meanwhile, by directly setting the front air outlet 215 to the air outlet 215 of the front panel 12, the positioning and installation of the dual-outlet fan 2 can be realized. Furthermore, it can eliminate the need to set up a connecting air duct between the front air outlet 215 and the air outlet 215 of the front panel 12, thereby reducing the airflow resistance caused by the bend and avoiding occupying the internal space of the volute 21, which is conducive to achieving a compact design of the air outlet device.

[0050] In some embodiments of this disclosure, reference is made to Figure 6 and Figure 8 As shown, the second air outlet 212 is constructed as a lower air outlet 215, and is located on the bottom plate 13 of the housing 1. Since the bottom plate 13 is located at the bottom of the housing 1, the airflow delivered through the lower air outlet 215 can be directly guided downwards to achieve downward airflow, reducing upward airflow loss and thus reducing energy consumption. This is beneficial for user scenarios where airflow needs to be guided downwards, and it also shortens the airflow path delivered through the second air duct 214, reducing airflow loss. Furthermore, it eliminates the need for a connecting air duct between the second air outlet 212 and the bottom plate 13, thus avoiding the need to occupy internal space in the housing 1, and facilitating a compact design of the air outlet device.

[0051] When using the air outlet device of this disclosure for heat exchange, the first air outlet mode can be switched when cooling is required. This allows airflow to be delivered from the front air outlet 215, forming a "canopy" air supply, achieving horizontal long-distance air supply, improving area coverage efficiency, and avoiding direct airflow onto the human body when delivered through the lower air outlet 215, which could cause discomfort. This optimizes the cooling experience. When heating is required, the second air outlet mode can be switched, allowing airflow to be delivered from the lower air outlet 215 to the ground, and then slowly rise after spreading along the ground, forming a "carpet" air supply. This avoids hot air rising rapidly, resulting in low temperatures at lower levels, which could affect comfort, and also reduces the accumulation of hot air at the ceiling, preventing waste.

[0052] In some embodiments of this disclosure, reference is made to Figures 1 to 4 , Figure 6 and Figure 8 As shown, the air outlet device includes a heat exchanger 3, which is located inside the housing 1 and positioned between the dual-outlet fan 2 and the air inlet 11. This allows the airflow entering the housing 1 from the air inlet 11 to first pass through the heat exchanger 3 for heat exchange, achieving heating or cooling, before entering the dual-outlet fan 2 for delivery. This avoids the situation where airflow is directly discharged without heat exchange, thus improving energy efficiency. Simultaneously, the location of the heat exchanger 3 at the air inlet 11 ensures that the temperature of the airflow exiting through the first air outlet 211 or the second air outlet 212 remains relatively consistent. This avoids the temperature difference between the airflow exiting the first air outlet 211 and the second air outlet 212, which would otherwise affect the user experience, as this would occur when the airflow is first heat-exchanged and then directed to the duct for discharge, compared to directly discharging the airflow after heat exchange. This helps ensure the stability of the outlet temperature.

[0053] Among them, such as Figure 4 As shown, a water receiving tray 5 can be installed inside the housing 1 to collect the condensate generated when the airflow passes through the heat exchanger 3, preventing water from seeping into internal components such as the motor 4 and circuits, thus affecting the normal operation of the equipment.

[0054] In some embodiments of this disclosure, reference is made to Figure 3 As shown, the housing 1 includes a rear plate 14, with an air inlet 11 located on the rear plate 14. Since the rear plate 14 is located at the rear of the housing 1, airflow can enter the interior from the rear side of the housing 1, avoiding interference with the airflow from the front or lower air outlet 215, which would affect the airflow volume and efficiency. This helps ensure airflow stability and allows the airflow to flow forward through the heat exchanger 3 to the dual-outlet fan 2, ensuring a straight flow path and improving airflow efficiency. Simultaneously, both the first and second airflow modes can be achieved through the air inlet 11 of the rear plate 14, simplifying the structure of the housing 1 and reducing manufacturing difficulty.

[0055] In some embodiments, the heat exchanger 3 is located in front of the air inlet 11 and behind the dual-outlet fan 2, so that the heat exchanger 3 is arranged downstream of the air inlet 11 and upstream of the dual-outlet fan 2.

[0056] In some embodiments of this disclosure, reference is made to Figures 1 to 10 As shown, the dual-outlet fan 2 is constructed as either a centrifugal fan or a cross-flow fan. The fan's volute 21 has an inlet 216, which communicates with the air inlet 11. When the dual-outlet fan 2 is constructed as a centrifugal fan, the inlet 216 is located on the axial side of the centrifugal fan, i.e., for axial air intake. In this case, the inlet 216 can communicate with the air inlet 11, meaning the inlet 216 and the air inlet 11 are spaced apart. When the dual-outlet fan 2 is constructed as a cross-flow fan, the inlet 216 is located on the radial side of the cross-flow fan, i.e., for radial air intake. The impeller of the cross-flow fan can be arranged outside the volute 21. In this case, the inlet 216 can also communicate with the air inlet 11, meaning the inlet 216 and the air inlet 11 are spaced apart.

[0057] In addition, centrifugal fans feature high static pressure and long air delivery distance, making them suitable for large spaces, long ducts, or scenarios requiring strong directional airflow to ensure sufficient airflow intensity. Cross-flow fans, on the other hand, offer uniform airflow and low noise, making them suitable for close-range use or scenarios with high noise reduction requirements, thus improving the comfort of the air delivery experience. This facilitates adaptation to different user needs and expands the range of applications.

[0058] According to a second aspect of this disclosure, an air conditioner is provided, including the air outlet device described above. This air conditioner has all the beneficial effects of the described air outlet device, which will not be elaborated further in this disclosure.

[0059] In some embodiments of this disclosure, the air conditioner is configured as a ducted unit. This allows for airflow from different directions when the ducted unit is installed on the ceiling of the room, such as front and bottom airflow, thus improving the user experience.

[0060] Below, for reference Figures 1 to 10 As shown, this disclosure will provide a detailed description of the specific usage process of the air outlet device in conjunction with the above-described specific embodiments. When cooling is required, the first air outlet mode can be adopted. Specifically, the airflow enters the housing 1 through the air inlet 11, and after being fully cooled by the heat exchanger 3, it enters the volute 21 through the inlet 216. The opening and closing mechanism 22 closes the air outlet 215 to prevent the airflow from entering the second air duct 214 and being blown out through the second air outlet 212. This allows the airflow entering the volute 21 to be sent to the first air outlet 211 through the first air duct 213 and blown out, thereby achieving front air outlet, preventing cold air from blowing directly onto the human body, and forming a "canopy" air supply to improve the area coverage efficiency.

[0061] When heating is required, the second air outlet mode can be used. Specifically, the airflow enters the housing 1 through the air inlet 11 and is fully heated by the heat exchanger 3. Then, it enters the volute 21 through the inlet 216. The opening and closing mechanism 22 opens the air outlet 215 and closes the first air inlet 11 to prevent the airflow from being blown out through the first air outlet 211. This allows the airflow entering the volute 21 to be sent to the second air outlet 212 through the second air duct 214 to achieve downward air outlet. As a result, the hot air can be sent to the ground through the downward air outlet 215 and slowly rise after spreading along the ground. This can form a "carpet" airflow, preventing the hot air from rising rapidly and causing the temperature at lower levels to be low, which would affect the comfort of the body.

[0062] Therefore, by switching between the first and second air outlet modes, the "front air outlet" and "bottom air outlet" modes can be switched to adapt to the needs of different scenarios.

However, this disclosure is not limited to the specific details of the above embodiments.

In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0065] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
