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: The housing has a partition inside, which divides the housing into a first cavity and a second cavity. The first cavity has a front air vent, and the second cavity has an air inlet. The partition has a connecting port that connects the first cavity and the second cavity. A dual-outlet fan is disposed within the second cavity and includes a front air outlet on a partition and a lower air outlet on the housing; and Opening and closing mechanism, used to open and close the connecting port, and to open and close the air inlet; The air outlet device has a front air outlet mode and a bottom air outlet mode. In the front air outlet mode, the opening and closing mechanism opens the air inlet and closes the connecting port; the front air outlet is used for air outlet, and the dual air outlet fan is either rotating in the forward or reverse direction. In the bottom air outlet mode, the opening and closing mechanism opens the connecting port and closes the air inlet; the front air outlet is used for air inlet, and the dual air outlet fan is either rotating in the forward or reverse direction.

[0005] Through the above technical solution, in the front-discharge mode, the opening and closing mechanism opens the air inlet, allowing external airflow to enter the second chamber through the air inlet located on the housing, thus achieving air intake. When the dual-outlet fan is rotating in either forward or reverse direction, the airflow entering the second chamber can be sent to the first chamber through the front air outlet, and then to the front air outlet, thereby achieving front-discharge of the air outlet device. Furthermore, in the front-discharge mode, the opening and closing mechanism also closes the connecting port, thereby preventing airflow interference caused by airflow entering the second chamber through the connecting port and exiting through the front air outlet.

[0006] In the bottom-discharge mode, the opening and closing mechanism opens the connecting port, allowing airflow entering the first chamber through the front air inlet to enter the second chamber through the connecting port, thus achieving front air intake. When the dual-air-outlet fan is either rotating in the forward or reverse direction, the airflow entering the second chamber can be discharged through the bottom air outlet, achieving bottom air outlet of the air outlet device. Furthermore, in the bottom-discharge mode, the opening and closing mechanism also closes the air inlet, thereby preventing airflow interference caused by airflow entering the second chamber through the air inlet and exiting through the bottom air outlet. Therefore, the air outlet device of this disclosure can achieve at least two air outlet modes, such as front air outlet and bottom air outlet, to meet the usage scenarios of different air outlet directions according to user needs. At the same time, the alternating use of the two air outlet modes is conducive to forming air circulation and improving ventilation efficiency.

[0007] In some possible implementations, at least one of the axial sides of the dual-outlet fan is used for air intake, the partition has at least one communication opening, and the housing has at least one air inlet. This allows the dual-outlet fan to have a stable air intake path, enabling accurate adaptation to different air outlet modes, facilitating mode switching of the air outlet device, and avoiding efficiency reduction caused by air intake interruptions.

[0008] In some possible implementations, both axial sides of the dual-outlet fan are used for air intake, the partition has at least two connecting openings, and the housing has at least two air inlets. In this way, both axial sides of the dual-outlet fan can be used for air intake, in conjunction with at least two connecting openings or at least two air inlets, thereby increasing the air intake area and air volume of the dual-outlet fan and improving airflow circulation efficiency.

[0009] In some possible implementations, the opening and closing mechanism includes a first opening and closing structure and a second opening and closing structure that move independently. The first opening and closing structure is used to open and close the connecting port, and the second opening and closing structure is used to open and close the air inlet. In this way, the air inlet paths of different air outlet modes can be completely isolated, avoiding the situation where, during linkage control, due to the delay in mechanical transmission action, one of the connecting port and the air outlet is not completely closed while the other has already opened, causing crosstalk in the airflow path.

[0010] In some possible implementations, the first opening and closing structure includes at least one first damper, which is rotatably or movably disposed on the partition to open or close the communication port; and / or, the second opening and closing structure includes at least one second damper, which is rotatably or movably disposed on the housing to open or close the air inlet. Thus, by driving the first damper to block or open the communication port, the opening and closing of the communication port can be achieved; and by driving the second damper to block or open the air inlet, the opening and closing of the air inlet can be achieved. The structure is simple and facilitates precise control.

[0011] In some possible implementations, the number of first dampers is at least two, and the first opening and closing structure includes a first driving member and a first connecting rod. The first driving member drives at least two first dampers to move synchronously via the first connecting rod. And / or, the number of second dampers is at least two, and the second opening and closing structure includes a second driving member and a second connecting rod. The second driving member drives at least two second dampers to move synchronously via the second connecting rod. This avoids situations where at least two connecting ports or at least two air inlets open and close asynchronously, causing airflow to enter the second cavity only from the open connecting port or air inlet, resulting in localized airflow concentration, uneven air intake for the dual-outlet fan, and affecting the stability of the air outlet.

[0012] In some possible implementations, a first opening and closing structure is provided on the side of the partition near the second cavity, and / or the second opening and closing structure is provided in the second cavity. This placement of the first opening and closing structure on the side of the partition near the second cavity avoids obstructing the air outlet passage of the first cavity and affecting air outlet efficiency. Placing the second opening and closing structure inside the second cavity avoids occupying external space on the outside of the housing, which is beneficial for achieving a compact design of the air outlet device.

[0013] In some possible implementations, the dual-outlet fan includes a volute housing with a front outlet and a lower outlet. A first outlet is provided on the partition, and the front outlet is located at the first outlet. A second outlet is provided on the housing, and the lower outlet is located at the second outlet. This avoids gaps between the front outlet and the first outlet, and between the lower outlet and the second outlet, which could lead to airflow leakage, affecting airflow efficiency, or causing noise due to turbulent airflow, thus impacting user experience.

[0014] In some possible implementations, the housing includes a base plate, and the second air outlet is disposed on the base plate. In this way, since the base plate is located at the bottom of the housing, when the lower air outlet of the dual-outlet fan is located at the second air outlet, the airflow delivered through the lower air outlet can be directly guided downward, which is beneficial for adapting to the lower air outlet mode.

[0015] In some possible implementations, the housing includes a base plate, and the air inlet is disposed on the base plate. This allows airflow to enter the second chamber through the base plate, avoiding the airflow loss caused by the need for detours when air enters from the side, thus shortening the air intake path and improving air intake efficiency.

[0016] In some possible implementations, the second cavity is equipped with at least two dual-outlet fans, wherein at least one motor drives each adjacent dual-outlet fan. In this way, the at least two dual-outlet fans can work together to increase the intake and exhaust air volume, enlarge the coverage area, and thus improve the airflow circulation efficiency of the exhaust device, adapting to the needs of large spaces.

[0017] In some possible implementations, the dual-outlet fan includes blades, the blades being constructed as arc-shaped blades, the arc-shaped blades being curved in a clockwise or counterclockwise direction, wherein at least two of the dual-outlet fans have blades that are curved in the same direction.

[0018] In some possible implementations, a mounting bracket is provided within the second cavity, and a pressure cap is connected to the mounting bracket. The pressure cap and the mounting bracket enclose an installation space, in which the motor is disposed. This mounting bracket and pressure cap secure the motor, preventing it from shifting due to vibration and affecting the precision of the transmission connection between the motor and the dual-outlet fan. This avoids transmission failure or reduced transmission efficiency, thus ensuring the stability of the motor transmission.

[0019] In some possible implementations, a heat exchanger is provided in the first cavity, and the opening and closing mechanism is located in the second cavity. In this way, with the heat exchanger located in the first cavity, when the air outlet device switches between the front air outlet mode and the bottom air outlet mode, the airflow can enter the first cavity and be fully heated by the heat exchanger before being sent out, thereby achieving temperature regulation of the airflow.

[0020] 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 air outlet configuration with the front and lower radial outlets of the dual-outlet fan, and allowing air to be drawn in axially through the connecting ports or inlets on both sides of the dual-outlet fan.

[0021] In some possible implementations, the dual-outlet fan includes blades configured as straight blades. This ensures that the thrust of the straight blades on the airflow remains consistent whether the dual-outlet fan is rotating forward or backward, avoiding the influence of blade curvature that could cause different airflow paths and resulting differences in air volume during forward and reverse rotation.

[0022] According to a second aspect of this disclosure, an air conditioner is provided, including the air outlet device as described above.

[0023] In some possible implementations, the air conditioner is configured as a ducted unit. In this way, when the ducted unit is installed inside the ceiling, the front air outlet can connect to the air outlet of the ceiling panel, and the lower air outlet can connect to the branch air duct within the ceiling, adapting to indoor installation scenarios and improving the user experience.

Detailed Implementation

[0027] 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.

In addition, 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 present disclosure.

[0029] According to a specific embodiment of this disclosure, refer to Figures 1 to 11 As shown, an air outlet device is provided, comprising: a housing 1, wherein a partition 9 is provided inside the housing 1, the partition 9 dividing the housing 1 into a first cavity 11 and a second cavity 12, the housing 1 having a front air inlet 14 in the first cavity 11 and an air inlet 15 in the second cavity 12, and the partition 9 having a connecting port 16 connecting the first cavity 11 and the second cavity 12; and a dual-outlet fan 2, disposed in the second cavity 12, and including a front air outlet 21 disposed on the partition 9 and a lower air outlet 22 disposed on the housing 1. The device includes an opening and closing mechanism 3 for opening and closing the connecting port 16 and the air inlet 15; the air outlet has a front air outlet mode and a bottom air outlet mode. In the front air outlet mode, the opening and closing mechanism 3 opens the air inlet 15 and closes the connecting port 16; the front air outlet 14 is used for air outlet, and the dual air outlet fan 2 is in either forward or reverse rotation. In the bottom air outlet mode, the opening and closing mechanism 3 opens the connecting port 16 and closes the air inlet 15; the front air outlet 14 is used for air inlet, and the dual air outlet fan 2 is in either forward or reverse rotation.

[0030] Through the above technical solution, in the front air outlet mode, the opening and closing mechanism 3 opens the air inlet 15, allowing external airflow to enter the second chamber 12 through the air inlet 15 located in the housing 1, thus achieving air intake. When the dual-outlet fan 2 is rotating in either forward or reverse direction, the airflow entering the second chamber 12 can be sent to the first chamber 11 through the front air outlet 21, and then to the front air outlet 14, thereby achieving front air outlet of the air outlet device. Furthermore, in the front air outlet mode, the opening and closing mechanism 3 also closes the connecting port 16, thereby preventing airflow interference to the air outlet via the front air outlet 21 when the airflow enters the second chamber 12 through the connecting port 16.

[0031] In the downward air outlet mode, the opening and closing mechanism 3 opens the connecting port 16, allowing the airflow entering the first chamber 11 through the front air inlet 14 to enter the second chamber 12 through the connecting port 16, thus achieving front air intake. When the dual-air outlet fan 2 is either rotating in the forward or reverse direction, the airflow entering the second chamber 12 can be sent out through the downward air outlet 22, thus achieving downward air outlet of the air outlet device. Furthermore, in the downward air outlet mode, the opening and closing mechanism 3 also closes the air inlet 15, thereby preventing airflow interference to the airflow exiting through the downward air outlet 22 when the airflow enters the second chamber 12 through the air inlet 15. Therefore, the air outlet device of this disclosure can realize at least two air outlet modes, such as front air outlet and downward air outlet, to meet the usage scenarios of air outlet in different directions according to user needs.

[0032] Furthermore, in the front air outlet mode, the front air outlet 14 is used for air outlet, and in the bottom air outlet mode, the front air outlet 14 is used for air inlet. Thus, through the cooperation of the opening and closing mechanism and the forward and reverse rotation of the dual air outlet fan, the front air outlet 14 can switch between air inlet and air outlet. Therefore, the air outlet device disclosed herein can also achieve reversible air supply.

[0033] When the air outlet device disclosed herein is used for heat exchange, it can switch to the front air outlet mode when cooling is required, so that the airflow can be sent out from the front air outlet 14 to form a "sky curtain" air supply, realize horizontal long-distance air supply, improve the area coverage efficiency, and avoid blowing directly onto the human body when it is sent out through the lower air outlet 22, which may cause physical discomfort. Therefore, it is beneficial to optimize the cooling experience.

[0034] When heating is needed, the system can switch to the down-draft mode, allowing airflow to be delivered from the down-draft outlet 22 to the ground and then slowly rise along the ground, forming a "carpet" of airflow. This prevents hot air from rising rapidly and causing low temperatures at lower levels, which would affect comfort. It also reduces the accumulation of hot air at the top of the room, thus avoiding waste.

[0035] It should be noted that this disclosure does not limit the specific structure of the opening and closing mechanism 3, which will be described in detail in the following embodiments. In addition, in the front air outlet mode, the dual air outlet fan 2 can be in reverse rotation, i.e., counterclockwise rotation, and in the bottom air outlet mode, the dual air outlet fan 2 can be in forward rotation, i.e., clockwise rotation. This disclosure does not limit this.

[0036] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 6 As shown, at least one of the axial sides of the dual-outlet fan 2 is used for air intake. The partition 9 is provided with at least one connecting port 16, and the housing 1 is provided with at least one air inlet 15. Thus, in the front-discharge mode, when the connecting port 16 is closed, the axial side of the dual-outlet fan 2 can draw airflow from the outside through at least one air inlet 15, thereby satisfying the air intake requirements of the dual-outlet fan 2. In the bottom-discharge mode, when the air inlet 15 is closed, the axial side of the dual-outlet fan 2 can draw airflow from the first chamber 11 through at least one connecting port 16, thereby satisfying the air intake requirements of the dual-outlet fan 2. Therefore, the dual-outlet fan 2 can have a stable air intake path to accurately adapt to different air outlet modes, realize mode switching of the air outlet device, and avoid efficiency reduction caused by air intake interruption.

[0037] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 6 As shown, the dual-outlet fan 2 has air intake on both axial sides. The partition 9 has at least two connecting ports 16, and the housing 1 has at least two air inlets 15. Thus, when both connecting ports 16 are open, the dual-outlet fan 2 can draw in airflow from both sides of the connecting ports 16, satisfying dual-sided air intake. Alternatively, when both air inlets 15 are open, the dual-outlet fan 2 can draw in airflow from both sides of the air inlets 15, satisfying dual-sided air intake. Therefore, the dual-outlet fan 2 can be used for air intake on both axial sides, in conjunction with at least two connecting ports 16 or at least two air inlets 15, thereby increasing the air intake area and air volume of the dual-outlet fan 2 and improving airflow circulation efficiency. Simultaneously, it enables uniform airflow distribution within the housing 1, avoiding local pressure imbalances and helping to ensure stability during the switching of the air outlet device's modes.

[0038] The system includes at least two connecting ports 16 located on both sides of the axis of the dual-outlet fan 2, and at least two air inlets 15 located on both sides of the axis of the dual-outlet fan 2. This allows the airflow on both sides of the axis of the dual-outlet fan 2 to fully participate in circulation, improving airflow circulation efficiency.

[0039] In some embodiments of this disclosure, reference is made to Figures 3 to 5 , Figure 8 and Figure 11 As shown, the opening and closing mechanism 3 includes a first opening and closing structure 31 and a second opening and closing structure 32, each moving independently. The first opening and closing structure 31 is used to open and close the connecting port 16, and the second opening and closing structure 32 is used to open and close the air inlet 15. In this way, the opening and closing of the connecting port 16 and the air inlet 15 can be controlled independently, achieving precise control through the first opening and closing structure 31 and the second opening and closing structure 32 respectively. This ensures that when switching between different air outlet modes, the air inlet paths of different air outlet modes can be isolated, avoiding the situation where, during linkage control, due to mechanical transmission delays, one of the connecting port 16 or the air outlet is not fully closed while the other is already open, causing crosstalk in the airflow path. Therefore, it helps to ensure the stability of the air outlet effect.

[0040] In some other embodiments of this disclosure, the opening and closing mechanism 3 is used to close the other of the air inlet 15 and the connecting port 16 when one of them is opened. In this way, the opening and closing mechanism 3 can selectively open and close the air inlet 15 and the connecting port 16, thereby simplifying the structure of the opening and closing mechanism 3 and facilitating maintenance and installation.

[0041] In some embodiments of this disclosure, reference is made to Figure 4 , Figure 8 and Figure 11 As shown, in the embodiment where the opening and closing mechanism 3 includes a first opening and closing structure 31 and a second opening and closing structure 32, the first opening and closing structure 31 includes at least one first damper 311, which is rotatably or movablely disposed on the partition 9 to open or close the communication port 16. Thus, by driving the first damper 311 to block or open the communication port 16, the opening and closing of the communication port 16 can be achieved; the structure is simple and facilitates precise control. The second opening and closing structure 32 includes at least one second damper 321, which is rotatably or movablely disposed on the housing 1 to open or close the air inlet 15. Thus, by driving the second damper 321 to block or open the air inlet 15, the opening and closing of the air inlet 15 can be achieved; the structure is simple and facilitates precise control. Furthermore, the connection method between the first damper 311 and the partition 9, and between the second damper 321 and the housing 1, can be selected according to the space and location of the installation scenario, which is beneficial for adapting to the needs of different locations.

[0042] In some embodiments of this disclosure, reference is made to Figure 4As shown, there are at least two first dampers 311. The first opening and closing structure 31 includes a first driving member 312 and a first connecting rod 313. The first driving member 312 drives at least two first dampers 311 to move synchronously through the first connecting rod 313. In this way, the synchronous opening and closing of at least two connecting ports 16 can be achieved by driving at least two first dampers 311 to move synchronously through the first connecting rod 313. There are at least two second dampers 321. The second opening and closing structure 32 includes a second driving member 322 and a second connecting rod 323. The second driving member 322 drives at least two second dampers 321 to move synchronously through the second connecting rod 323. The synchronous opening and closing of at least two air inlets 15 can be achieved by driving at least two second dampers 321 to move synchronously through the second connecting rod 323. Therefore, it avoids the situation where at least two connecting ports 16 or at least two air inlets 15 open and close asynchronously, causing airflow to enter the second cavity 12 only from the open connecting ports 16 or air inlets 15, resulting in localized airflow concentration, uneven air intake of the dual-air-port fan 2, and affecting the stability of the air output.

[0043] Both the partition plate 9 and the housing 1 are provided with mounting bases 33. The first connecting rod 313 can be installed on the partition plate 9 through the mounting base 33 to rotatably or movablely connect the first damper 311 to the partition plate 9. The second connecting rod 323 can be installed on the housing 1 through the mounting base 33 to rotatably or movablely connect the second damper 321 to the housing 1.

[0044] In some embodiments, the first drive member 312 can drive at least two first dampers 311 to rotate via the first connecting rod 313. In this way, compared to driving at least two first dampers 311 to move, the size of the housing in the direction of movement of the first dampers 311 is too large. The above-mentioned rotation method is beneficial to reduce the volume of the housing 1.

[0045] Similarly, the second drive member 322 can drive at least two second dampers 321 to rotate via the second link 323. In this way, compared to driving at least two second dampers 321 to move, which would cause the size of the housing 1 to be too large in the direction of movement of the second dampers 321, the above-mentioned rotation method is beneficial to reduce the volume of the housing 1.

[0046] In some embodiments of this disclosure, reference is made to Figure 8 and Figure 11As shown, a first opening and closing structure 31 is provided on the side of the partition 9 near the second cavity 12. This placement of the first opening and closing structure 31 on the side of the partition 9 near the second cavity 12 avoids the partition 9 being located near the first cavity 11, which would occupy the air outlet space within the first cavity 11, thus preventing airflow obstruction in both front and bottom air outlet modes and affecting air outlet efficiency. A second opening and closing structure 32 is provided in the second cavity 12. This placement of the second opening and closing structure 32 within the second cavity 12 avoids it occupying external space on the outside of the housing 1, thereby facilitating a compact design of the air outlet device.

[0047] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the dual-outlet fan 2 includes a volute 24, which has a front outlet 21 and a lower outlet 22. A partition 9 has a first outlet 18, with the front outlet 21 located at the first outlet 18. The housing 1 has a second outlet 17, with the lower outlet 22 located at the second outlet 17. Thus, with the front outlet 21 of the volute 24 located at the first outlet 18, in front-outlet mode, the airflow delivered through the front outlet 21 can directly enter the first cavity 11 through the first outlet 18, and then exit through the front outlet 14, thereby shortening the airflow path in front-outlet mode. In lower-outlet mode, the airflow delivered through the lower outlet 22 can directly exit the housing 1 through the second outlet 17, further shortening the airflow path in lower-outlet mode. This avoids gaps between the front air outlet 21 and the first air outlet 18, and between the lower air outlet 22 and the second air outlet 17, which could lead to air leakage, affecting air outlet efficiency, or causing noise due to turbulent airflow, thus impacting user experience. Simultaneously, it allows for the installation and positioning of the dual-outlet fan 2 via the first air outlet 18 and the second air outlet 17, and eliminates the need for connecting air ducts between the front air outlet 21 and the first air outlet 18, and between the lower air outlet 22 and the second air outlet 17, thus saving internal space in the second cavity 12 and facilitating a compact design of the air outlet device.

[0048] In some embodiments of this disclosure, reference is made to Figure 2 , Figure 7 and Figure 10 As shown, the housing 1 includes a base plate 13, and a second air outlet 17 is disposed on the base plate 13. In this way, since the base plate 13 is located at the bottom of the housing 1, when the lower air outlet 22 of the dual-outlet fan 2 is disposed on the second air outlet 17, the airflow delivered through the lower air outlet 22 can be directly guided downward, which is beneficial for adapting to the downward air outlet mode, meeting the usage scenarios that require airflow to be guided to the ground, and can shorten the airflow path, reduce the upward loss of airflow, thereby reducing losses.

[0049] In some embodiments of this disclosure, reference is made to Figure 2 , Figure 7 and Figure 10 As shown, the housing 1 includes a base plate 13, and an air inlet 15 is disposed on the base plate 13. In this way, the airflow can enter the second cavity 12 through the base plate 13, avoiding the airflow loss caused by the need for detours when the air is introduced from the side. This helps to shorten the air intake path, improve the air intake efficiency, and realize the downward air intake in the front air outlet mode. Furthermore, it is beneficial to adapt to the front air outlet mode to avoid the air intake path from colliding with the airflow of the front air outlet 14, which would cause airflow interference and help improve the stability of the front air outlet mode.

[0050] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 3 , Figure 6 and Figure 9 As shown, the second cavity 12 is equipped with at least two dual-outlet fans 2, wherein at least one motor 4 drives two adjacent dual-outlet fans 2. Thus, 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, enlarge the coverage area, and improve the airflow circulation efficiency of the air outlet device, adapting to the needs of large spaces. Furthermore, it ensures that the rotational speeds of adjacent dual-outlet fans 2 are consistent, avoiding mutual airflow interference, ensuring the reliability of the air outlet device, and reducing the number of motors 4 required, thus reducing the area occupied by the motors 4, achieving a compact design of the air outlet device, and reducing production costs. Of course, the at least two dual-outlet fans 2 can each be driven by a separate motor 4; this disclosure does not impose any limitation on this.

[0051] The partition 9 can have at least three connecting ports 16, and the partition 9 has connecting ports 16 located between two adjacent dual-outlet fans 2; the housing 1 can have at least three air inlets 15, and the housing 1 has air inlets 15 located between two adjacent dual-outlet fans 2. In this way, connecting ports 16 can be provided on both axial sides of two adjacent dual-outlet fans 2, so that in the downward air outlet mode, airflow can be drawn in from both axial sides of each dual-outlet fan 2. Simultaneously, air inlets 15 can be provided on both sides of two adjacent dual-outlet fans 2, so that in the forward air outlet mode, airflow can be drawn in from both axial sides of each dual-outlet fan 2. This ensures that the airflow drawn in when two adjacent dual-outlet fans 2 operate simultaneously is evenly distributed, avoiding the situation where the air pressure in the middle area is too low due to only having connecting ports 16 and air inlets 15 on both sides.

[0052] In some embodiments of this disclosure, the dual-outlet fan includes blades 23, which can be configured as arc-shaped blades. The arc-shaped blades bend in either a clockwise or counterclockwise direction, wherein the blades 23 of at least two dual-outlet fans 2 bend in the same direction. Thus, the blades 23 of two adjacent dual-outlet fans 2 can both be set to a clockwise or counterclockwise direction. Therefore, when driving at least two dual-outlet fans 2 to rotate in the same direction, the airflow direction can be kept consistent, avoiding mutual interference between the airflow of adjacent dual-outlet fans 2 and affecting the airflow efficiency and stability.

[0053] The blades 23 of two adjacent dual-outlet fans 2 can be bent in opposite directions. That is, the blades 23 of one dual-outlet fan 2 are bent clockwise, and the blades 23 of the other dual-outlet fan 2 are bent counterclockwise. In this way, in both the front air outlet mode and the bottom air outlet mode, the blades 23 of two adjacent dual-outlet fans can have the same bending direction as the rotation direction of the dual-outlet fan 2, and the opposite bending direction of the blades 23, so as to ensure that the air volume in the front air outlet mode and the bottom air outlet mode can be kept consistent. This disclosure does not impose any specific restrictions on this.

[0054] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 3 As shown, a mounting bracket 5 is provided inside the second cavity 12, and a pressure cap 6 is connected to the mounting bracket 5. The pressure cap 6 and the mounting bracket 5 enclose an installation space, in which the motor 4 is installed. In this way, the mounting bracket 5 and the pressure cap 6 securely mount the motor 4, preventing it from shifting due to vibration and affecting the precision of the transmission connection between the motor 4 and the dual-outlet fan 2. This avoids transmission failure or reduced transmission efficiency, thus ensuring the stability of the motor 4's transmission. Simultaneously, the pressure cap 6 and the mounting bracket 5 provide protection for the motor 4, preventing impurities from directly contacting it and causing wear on internal parts, thus extending the motor 4's service life.

[0055] The motor 4 can be positioned between two adjacent dual-outlet fans 2 to drive them to operate synchronously. A first damper 311 located between the two adjacent dual-outlet fans 2 has a first clearance opening 3111, and a second damper 321 has a second clearance opening 3211 to avoid interference with the mounting frame 5, preventing the movement of the first damper 311 and the second damper 321 from interfering with the mounting frame 5. Furthermore, the drive shaft 41 of the motor 4 can be coaxially mounted and connected to the impellers of the two adjacent dual-outlet fans 2, so that the rotation of the drive shaft 41 can drive the two adjacent dual-outlet fans 2 to operate synchronously.

[0056] In some embodiments of this disclosure, reference is made to Figures 1 to 3 , Figures 5 to 11As shown, a heat exchanger 7 is installed in the first chamber 11, and an opening / closing mechanism 3 is installed in the second chamber 12. Thus, when the air outlet device is in front-outlet mode, the airflow entering the first chamber 11 through the front outlet 21 of the dual-outlet fan 2 can be heated by the heat exchanger 7 and then discharged through the front outlet 14. When the air outlet device is in bottom-outlet mode, the airflow entering the first chamber 11 through the front outlet 14 can be heated by the heat exchanger 7 and then enter the second chamber 12 through the connecting port 16, so that the dual-outlet fan 2 can draw it in and discharge it through the bottom outlet 22. Therefore, with the heat exchanger 7 installed in the first chamber 11, the airflow can be fully heated by the heat exchanger 7 before being discharged when the air outlet device switches between front-outlet and bottom-outlet modes, thereby achieving temperature regulation of the airflow.

[0057] Among them, such as Figure 3 As shown, a water receiving tray 8 can be installed in the first cavity 11 to collect the condensate generated when the airflow passes through the heat exchanger 7, preventing water from seeping into internal components such as motors and circuits and affecting the normal operation of the equipment.

[0058] In some embodiments of this disclosure, the dual-outlet fan 2 is constructed as a centrifugal fan. This centrifugal fan enables axial air intake and radial air exhaust, facilitating airflow through the front outlet 21 and lower outlet 22 on the radial side of the dual-outlet fan 2, and also facilitating air intake through the connecting ports 16 or inlets 15 located on both axial sides of the dual-outlet fan 2. Therefore, in the front-outlet mode, airflow enters the first chamber 11 from the inlets 15 located on both axial sides of the dual-outlet fan 2, and after being drawn in by the dual-outlet fan 2, exits through the front outlet 21. In the lower-outlet mode, airflow enters the first chamber 11 from the connecting ports 16 located on both axial sides of the fan, and after being drawn in by the dual-outlet fan 2, exits through the lower outlet 22.

[0059] In some embodiments of this disclosure, reference is made to Figure 3 As shown, the dual-outlet fan 2 includes blades 23, which are constructed as straight blades. Because the straight blades 23 are geometrically symmetrical, the thrust of the straight blades 23 on the airflow remains consistent whether the dual-outlet fan 2 rotates forward or backward. This ensures that the airflow volume at the front outlet and the airflow volume at the bottom outlet are essentially the same, avoiding the influence of the blade curvature, which could cause differences in airflow paths and airflow volume during forward and reverse rotation. This facilitates adaptation to the switching requirements between front and bottom outlet modes, ensuring consistent airflow delivery efficiency.

[0060] 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 upon further in this disclosure.

[0061] In some embodiments of this disclosure, the air conditioner is configured as a ducted unit. This allows for both front and bottom airflow when the ducted unit is installed on the ceiling of the room, thus improving the user experience.

[0062] Below, for reference Figures 1 to 11 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, a front-outlet mode with bottom air intake and front air outlet can be adopted. Specifically, the first opening and closing structure 31 closes the connecting port 16 to prevent airflow from entering the second chamber 12 from the front, and the second opening and closing structure 32 opens the air inlet 15, allowing external airflow to enter the second chamber 12 through the air inlet 15 and be sent to the first chamber 11 through the front air outlet 21 of the dual-outlet fan 2. This allows the heat exchanger 7 to fully exchange heat with the airflow entering the first chamber 11 before it is sent out through the front air outlet 14. Thus, by using front-outlet air outlet, cold air can be prevented from blowing directly onto the human body, and a "canopy" air supply can be formed, improving the area coverage efficiency.

[0063] When heating is required, a bottom-exit mode with front air intake and bottom air outlet can be adopted. Specifically, the second opening and closing structure 32 opens the connecting port 16, allowing the airflow entering the first chamber 11 through the front air outlet 14 to be fully heated by the heat exchanger 7 before entering the second chamber 12 through the connecting port 16 and being discharged from the casing 1 through the bottom air outlet 22 of the dual-outlet fan 2. Thus, hot air can be delivered to the ground through the bottom air outlet 22, diffuse along the ground, and slowly rise, forming a "carpet" of airflow to prevent the rapid rise of hot air from causing low temperatures at lower levels and affecting comfort.

[0064] Therefore, by switching between the front air outlet mode and the bottom air outlet mode, the switching between "bottom air inlet and front air outlet" and "front air inlet and bottom air outlet" can be realized, thereby achieving reversible air supply.

[0065] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0066] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0067] 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.
