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 the user experience.

[0004] To achieve the above objectives, this disclosure provides an air outlet device, comprising: a housing, wherein a partition is provided within the housing to divide the housing into a first cavity and a second cavity, the housing having a first air outlet in the first cavity and an air inlet in the second cavity, and the partition having a connecting port connecting the first cavity and the second cavity; a dual-outlet fan, disposed within the second cavity, and including a volute, the volute including a first air outlet and a second air outlet disposed within the housing, the first air outlet communicating with the first cavity, and a first opening and closing mechanism provided within the volute for allowing air to... The air outlet device has a first air outlet or a second air outlet; and a second opening and closing mechanism for opening and closing the connecting port and the air inlet; the air outlet device has a first air outlet mode or a second air outlet mode, in the first air outlet mode, the second opening and closing mechanism opens the air inlet and closes the connecting port; the first opening and closing mechanism is used to allow airflow to be blown out from the first air outlet, and the first air outlet is used for air outlet; in the second air outlet mode, the second opening and closing mechanism opens the connecting port and closes the air inlet; the first opening and closing mechanism is used to allow airflow to be blown out from the second air outlet, and the first air outlet is used for air inlet.

[0005] Through the above technical solution, in the first air outlet mode, the second opening and closing mechanism closes the connecting port and opens the air inlet, allowing external airflow to enter the second cavity through the air inlet. The rotation of the dual-outlet fan drives the airflow into the second cavity into the volute, and the first opening and closing mechanism causes the airflow inside the volute to be blown from the first air outlet to the first cavity, exiting through the first air outlet. In the second air outlet mode, external airflow enters the first cavity through the first air outlet. The second opening and closing mechanism closes the air inlet and opens the connecting port, allowing the airflow into the first cavity to enter the second cavity through the connecting port. The rotation of the dual-outlet fan drives the airflow into the second cavity into the volute, and the first opening and closing mechanism causes the airflow inside the volute to be blown out of the housing through the second air outlet. Therefore, the airflow entering the housing can have different inlet and outlet paths, enabling airflow to enter through the first air outlet and exit through the second air outlet, or vice versa, 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 first 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 arrangement 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 avoiding a reduction in airflow efficiency.

[0009] In some possible implementations, the first air duct and the second air duct are connected via a second air outlet. The opening / closing member has a first position and a second position. In the first position, the opening / closing member opens the first air outlet and closes the second air outlet to close the second air outlet. In the second position, the opening / closing member closes the first air outlet and opens the second air outlet to open the second air outlet. Thus, when the opening / closing member is in the first position, the airflow entering the volute can exit through the first air outlet, and the first and second air ducts are isolated, preventing airflow from continuing to flow into the second air duct. When the opening / closing member is in the second position, the airflow entering the volute can exit through the second air outlet, preventing airflow from being blown out from the first air outlet and causing diversion, which would affect the airflow efficiency.

[0010] In some possible implementations, the opening / closing element is rotatably disposed at the end of the second air outlet near the first air outlet. 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.

[0011] In some possible implementations, the first opening and closing mechanism includes a third driving member disposed within the volute and used to drive the opening and closing member to move. In this way, the third driving member can be integrated within the volute, reducing the space occupied within the housing, while simultaneously shortening the transmission distance and improving transmission efficiency.

[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 downward air duct extending vertically, with the second air outlet for downward airflow. Thus, in a first airflow mode, the airflow can be guided forward through the first air duct to be directed forward through the first air outlet. In a second airflow mode, the airflow can be guided downward through the second air duct to be directed downward through the second air outlet. This adapts to the user's needs for different airflow directions in different scenarios.

[0013] In some possible implementations, the first air outlet is located on the partition. In this way, the airflow delivered through the first air outlet can directly enter the first cavity through the partition, which helps to shorten the airflow path from the first air duct to the first cavity.

[0014] In some possible implementations, the first air outlet is configured as a front air outlet, with the first air vent located in front of the first air outlet. In this way, the airflow sent forward to the first chamber via the first air outlet can be directly sent forward through the front air vent, ensuring the air delivery efficiency of the airflow sent from the first air outlet to the first air vent.

[0015] In some possible implementations, the second air outlet is configured as a downward air outlet, located on the bottom plate of the housing. This allows the airflow delivered through the downward air outlet to be directed directly downwards, reducing upward airflow and thus minimizing losses.

[0016] In some possible implementations, the second cavity is equipped with at least two dual-outlet fans, wherein two adjacent dual-outlet fans are driven by the same motor, and / or two adjacent first opening and closing mechanisms move synchronously. In this way, at least two dual-outlet fans can work together to increase the intake and exhaust air volume, thereby increasing the coverage area. Furthermore, this avoids mutual interference or collision of airflow when adjacent dual-outlet fans are discharging air, preventing airflow loss or noise generation.

[0017] In some possible implementations, the first opening and closing mechanism includes opening and closing elements, with two adjacent opening and closing elements driven by the same drive shaft, which is disposed between two adjacent volutes. Thus, by rotating the drive shaft, the adjacent opening and closing mechanisms can move synchronously, thereby ensuring that the airflow direction delivered by two adjacent dual-outlet fans remains consistent.

[0018] In some possible implementations, the drive shaft is connected to a third drive member, which is located on the side of one of the volutes away from the other. This single-sided placement of the third drive member allows for synchronous movement of two adjacent opening and closing components, simplifying the power transmission path, reducing transmission complexity, and improving power transmission efficiency.

[0019] In some possible implementations, the second cavity is provided with at least two dual-outlet fans, which are arranged at intervals along the axial direction. This arrangement of at least two dual-outlet fans helps to ensure sufficient airflow, and the axial spacing helps to ensure adequate airflow coverage.

[0020] In some possible implementations, the dual-outlet fan is constructed as a centrifugal fan.

[0021] In some possible implementations, the partition has a connecting opening between two adjacent dual-outlet fans; the housing has an air inlet between two adjacent dual-outlet fans; and / or, the partition has the connecting opening in the axial direction outside the dual-outlet fans; the housing has the air inlet in the axial direction outside the dual-outlet fans. This placement of the air inlet and connecting opening between two adjacent dual-outlet fans ensures uniform airflow diffusion within the second cavity, guaranteeing sufficient airflow to both adjacent fans and preventing insufficient local airflow. By providing the connecting opening and air inlet outside the dual-outlet fans, it facilitates airflow circulation in the outer area, improving airflow efficiency.

[0022] In some possible implementations, the connecting port and the air inlet are arranged in pairs, and the dual-outlet fan has a fan inlet on at least one side in the axial direction, with at least one pair of connecting ports and air inlets on the same side of the fan inlet. This arrangement of the connecting ports and air inlets close to the fan inlet helps to shorten the airflow distance within the second cavity, reducing the airflow path and thus lowering airflow loss, thereby improving the airflow efficiency of the first and second air outlet modes.

[0023] In some possible implementations, the fan inlets are located on adjacent sides of two adjacent dual-outlet fans, and at least one pair of connecting ports and air inlets are provided between the two adjacent fan inlets. Thus, in the second air outlet mode, the airflow entering the second chamber via the connecting port is shortened, with the flow path between the connecting port and the two fan inlets. In the first air outlet mode, the airflow entering the second chamber via the air inlets is shortened, with the flow path between the air inlets and the two fan inlets.

[0024] In some possible implementations, the second opening and closing mechanism includes a first opening and closing structure and a second opening and closing structure that move independently of each other. 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 opening and closing of the connecting port and the air inlet can be controlled independently, so as to achieve precise control of opening and closing through the first opening and closing structure and the second opening and closing structure respectively.

[0025] 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. 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.

[0026] 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. Thus, by driving at least two first dampers to move synchronously via the first connecting rod, the synchronous opening and closing of at least two connecting ports can be achieved. By driving at least two second dampers to move synchronously via the second connecting rod, the synchronous opening and closing of at least two air inlets can be achieved.

[0027] In some possible implementations, a first opening and closing structure is provided on the side of the partition near the second cavity, and / or, a second opening and closing structure is provided in the second cavity. This avoids the first opening and closing structure occupying the air outlet space within the first cavity when it is located on the side of the partition near the first cavity. It also avoids the second opening and closing structure occupying external space when located outside the housing, thereby facilitating a compact design of the air outlet device.

[0028] In some possible implementations, the second opening and closing mechanism is used to close the other of the connecting port and the air inlet when one of them is opened. This allows the second opening and closing mechanism to selectively open or close the air inlet and the connecting port, simplifying its structure and facilitating maintenance and installation.

[0029] In some possible implementations, a heat exchanger is provided in the first cavity, and the second opening and closing mechanism is located in the second cavity. In this way, when the air outlet device switches between the first air outlet mode and the second air outlet mode, the airflow can be fully heat-exchanged through the heat exchanger before being delivered, thereby achieving temperature regulation of the airflow.

[0030] In some possible implementations, the dual-outlet fan is constructed as a centrifugal fan or a cross-flow fan, with the fan casing having a fan inlet that communicates with the air inlet. This facilitates adaptation to different user needs and expands the application range.

[0031] According to a second aspect of this disclosure, an air conditioner is provided, including the air outlet device as described above.

[0032] 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.

[0036] 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.

Figure 1 and Figure 2 The arrows indicating "left and right directions" are used in the text. 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.

[0038] According to a specific embodiment of this disclosure, refer to Figures 1 to 9As shown, an air outlet device is provided, comprising: a housing 1, wherein a partition 7 is provided inside the housing 1, the partition 7 dividing the housing 1 into a first cavity 11 and a second cavity 12, the housing 1 having a first air outlet 14 in the first cavity 11 and an air inlet 15 in the second cavity 12, the partition 7 having a connecting port 16 connecting the first cavity 11 and the second cavity 12; a dual-outlet fan 2, disposed in the second cavity 12, and including a volute 21, the volute 21 including a first air outlet 211 and a second air outlet 212 disposed in the housing 1, the first air outlet 211 communicating with the first cavity 11, and a first opening and closing mechanism 22 provided inside the volute 21, the first opening and closing mechanism 22 being used to... Airflow is blown out from the first air outlet 211 or the second air outlet 212; and a second opening and closing mechanism 3 is used to open and close the connecting port 16 and the air inlet 15; the air outlet device has a first air outlet mode or a second air outlet mode. In the first air outlet mode, the second opening and closing mechanism 3 opens the air inlet 15 and closes the connecting port 16; the first opening and closing mechanism 22 is used to allow airflow to be blown out from the first air outlet 211, and the first air outlet 14 is used for air outlet; in the second air outlet mode, the second opening and closing mechanism 3 opens the connecting port 16 and closes the air inlet 15; the first opening and closing mechanism 22 is used to allow airflow to be blown out from the second air outlet 212, and the first air outlet 14 is used for air inlet.

[0039] Through the above technical solution, in the first air outlet mode, the second opening and closing mechanism 3 closes the connecting port 16 and opens the air inlet 15, so that the external airflow can enter the second cavity 12 through the air inlet 15. The rotation of the dual-air outlet fan 2 can drive the airflow entering the second cavity 12 into the volute 21. The first opening and closing mechanism 22 causes the airflow in the volute 21 to be blown from the first air outlet 211 to the first cavity 11, so as to be discharged through the first air outlet 14. Thus, in the first air outlet mode, the first air outlet 14 can be used for air discharge. In the second air outlet mode, external airflow enters the first cavity 11 through the first air inlet 14. The second opening and closing mechanism 3 closes the air inlet 15 and opens the connecting port 16, allowing the airflow entering the first cavity 11 to enter the second cavity 12 through the connecting port 16. The rotation of the dual-air outlet fan 2 drives the airflow entering the second cavity 12 into the volute 21, and the first opening and closing mechanism 22 causes the airflow inside the volute 21 to be blown out of the housing 1 through the second air outlet 212. Thus, in the second air outlet mode, the second air outlet 212 can be used for air outlet. Therefore, in the first and second air outlet modes, airflow can be blown out from different outlets, meaning the air outlet device has at least two air outlet modes to meet different usage scenarios according to user needs.

[0040] Furthermore, in the first air outlet mode, the first air outlet 14 is used for air outlet, and in the second air outlet mode, the first air outlet 14 is used for air inlet. Thus, by cooperating with the first opening and closing mechanism 22 and the second opening and closing mechanism 3 and the dual air outlet fan 2, the first air outlet 14 can switch between air inlet and air outlet. Therefore, the air outlet device of this disclosure can also achieve reversible air supply.

[0041] In some embodiments of this disclosure, reference is made to Figure 6 and Figure 8 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.

[0042] In some embodiments of this disclosure, reference is made to Figure 4 , Figure 6 and Figure 8 As shown, the volute 21 includes a first air duct 213 and a second air duct 214. The first air duct 213 is provided with a first air outlet 211, and the second air duct 214 is provided with a second air outlet 212. In this way, after the dual-outlet fan 2 drives the airflow into the volute 21, since the first air duct 213 is provided with a first air outlet 211, by introducing the airflow into the first air duct 213, the airflow can be guided to the first air outlet 211, so as to realize the air outlet 211.

[0043] Similarly, since the second air duct 214 is provided with a second air outlet 212, air can be discharged from the second air outlet 212 by introducing airflow into the second air duct 214. Thus, according to the direction of the first air duct 213 and the second air duct 214, the airflow can be directed to one of the first air duct 213 and the second air duct 214, thereby enabling control over whether the airflow is blown out from the first air outlet 211 or the second air outlet 212.

[0044] In some embodiments of this disclosure, reference is made to Figure 4 , Figure 6 and Figure 8As shown, the first 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 first 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 thus 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 thus 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.

[0045] Of course, in other embodiments, the first 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.

[0046] In some embodiments, when the opening orientation of the second air inlet 15 is the same as that of the air inlet 15, it can also prevent the airflow diverted to the second air outlet 212 in the first air outlet mode from interfering with the airflow entering through the air inlet 15, thus affecting the air intake efficiency. When the opening orientation of the first air inlet 15 is the same as that of the connecting port 16, it can also prevent the airflow diverted to the first air outlet 211 in the second air outlet mode from interfering with the airflow entering through the connecting port 16, thus affecting the air intake efficiency.

[0047] In some embodiments of this disclosure, reference is made to Figure 4 , Figure 6 and Figure 8 As shown, the first air duct 213 and the second air duct 214 are connected through the second 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 second 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. Furthermore, by closing the second air outlet 215, the first air duct 213 and the second air duct 214 can be isolated, preventing the airflow from continuing to flow into the second air duct 214, which is beneficial to improving the airflow efficiency.

[0048] In the second position, the opening / closing element 221 closes the first air outlet 211 and opens the second air outlet 215 to open the second air outlet 212. When the opening / closing element 221 is in the second position, the airflow entering the volute 21 can enter the second air duct 214 through the first air duct 213, and flow to the second air outlet 212 through the second air duct 214 to exit through the second air outlet 212. The opening / closing element 221 closes the first air outlet 211 to prevent the airflow from being blown out of the first air outlet 211 and causing diversion, which would affect the air outlet efficiency.

[0049] In some embodiments of this disclosure, reference is made to Figure 4 , Figure 6 and Figure 8 As shown, the opening / closing element 221 is rotatably disposed at the end of the second 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 second 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.

[0050] In some embodiments of this disclosure, reference is made to Figure 2 As shown, the first opening and closing mechanism 22 includes a third 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 third 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 third 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, improve transmission efficiency, and reduce power loss.

[0051] In some embodiments of this disclosure, reference is made to Figure 4 , Figure 6 and Figure 8 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 in the second cavity 12 enters the dual-outlet fan 2, it can be guided forward through the first air duct 213 to be directionally delivered forward through the first air outlet 211. 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.

[0052] 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 12 enters the dual-outlet fan 2, it can be guided downward through the second air duct 214 and directed downward through the second air outlet 212. This achieves downward airflow in the second airflow mode, meeting the user's need for downward airflow and preventing airflow from stagnating at the top and failing to circulate adequately 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.

[0053] When the air outlet device of this disclosure is used for heat exchange, it can switch to the first air outlet mode when cooling is required, so that the airflow can be sent forward from the first air outlet 211 and sent forward from the housing 1 through the first air outlet 14 to form a "sky curtain" air supply, realize horizontal long-distance air supply, improve the area coverage efficiency, and avoid the cold air blowing directly onto the human body when it is sent downward through the second air outlet 212, which would cause physical discomfort. Therefore, it is beneficial to optimize the cooling experience.

[0054] When heating is needed, the system can switch to the second air outlet mode, allowing airflow to be sent downwards from the second air outlet 212 to the ground, and then slowly rises after spreading along the ground, forming a "carpet" airflow. This avoids the rapid rise of hot air, which would cause the temperature at lower levels to drop, affecting the comfort of the body, and also reduces the accumulation of hot air at the top of the room, thus avoiding waste.

[0055] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the first air outlet 211 is located on the partition 7. This allows the airflow from the first air outlet 211 to directly enter the first cavity 11 through the partition 7, shortening the airflow path from the first air duct 213 to the first cavity 11. Simultaneously, by directly placing the first air outlet 211 on the partition 7, the dual-outlet fan 2 can be positioned and installed. Furthermore, when the airflow from the first air outlet 211 is delivered to the first cavity 11, the need for a connecting air duct between the first air outlet 211 and the partition 7 is eliminated, avoiding the occupation of internal space in the second cavity 12 and facilitating a compact design of the air outlet device.

[0056] In some embodiments of this disclosure, reference is made to Figures 1 to 3 , Figure 5 and Figure 7As shown, the first air outlet 211 is configured as a front air outlet, and the first air vent 14 is located in front of the first air outlet 211. In this way, the airflow sent forward to the first cavity 11 through the first air outlet 211 can be directly sent forward through the first air vent 14 on the front side. The straight path of the airflow helps to ensure the air delivery efficiency of the airflow sent from the first air outlet 211 to the first air vent 14, reduces the airflow resistance caused by bends, reduces airflow loss, and enables front airflow through the first air vent 14 to meet user needs and avoid direct airflow onto the human body causing discomfort.

[0057] In some embodiments of this disclosure, reference is made to Figures 1 to 3 , Figure 5 and Figure 7 As shown, the second air outlet 212 is configured as a downward air outlet, 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 downward air outlet 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, reducing airflow loss and further reducing energy consumption. Simultaneously, 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 second cavity 12, and facilitates a compact design of the air outlet device.

[0058] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the second cavity 12 is equipped with at least two dual-outlet fans 2, with adjacent dual-outlet fans 2 driven by the same motor 4. 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 are consistent, avoiding mutual airflow interference, ensuring the reliability of the air outlet device, and reducing the number of motors 4 to minimize their footprint, achieving a compact design and reducing 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.

[0059] 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.

[0060] In some embodiments of this disclosure, reference is made to Figure 6 and Figure 8As shown, the two adjacent first opening and closing mechanisms 22 move synchronously. This allows control of both adjacent dual-outlet fans to be in the first air outlet mode, opening the first air outlet 211 and closing the second air outlet 212. This ensures that the airflow from both adjacent dual-outlet fans 2 can exit through the first air outlet 211, guaranteeing the airflow volume in the first air outlet mode. Alternatively, both adjacent dual-outlet fans 2 can be in the second air outlet mode, opening the second air outlet 212 and closing the first air outlet 211. This ensures that the airflow from both adjacent dual-outlet fans 2 can exit through the second air outlet 212, guaranteeing the airflow volume in the second air outlet mode. This avoids mutual interference or collision of airflow when adjacent dual-outlet fans 2 are discharging air, preventing airflow loss or noise, and thus improving airflow efficiency and user experience.

[0061] In some embodiments of this disclosure, reference is made to Figure 2 As shown, the first opening and closing mechanism 22 includes opening and closing elements 221. Two adjacent opening and closing elements 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 two adjacent dual-outlet fans 2 can be opened and closed synchronously, or the second air outlets 212 of two adjacent dual-outlet fans 2 can be opened and closed synchronously, achieving synchronous movement of the two adjacent opening and closing mechanisms. This ensures that the airflow direction from 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 and closing elements 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 and closing elements 221 and to fully utilize the space between the two adjacent volutes 21, optimizing the internal space utilization of the air outlet device. This facilitates a compact design and avoids interference with the airflow path of the dual-outlet fans 2, ensuring the stability of the airflow.

[0062] In some embodiments of this disclosure, reference is made to Figure 2 As shown, the drive shaft is connected to the third drive member 222, which is located on the side of one of the volute housings 21 away from the other. By setting the third drive member 222 on one side, it can be directly connected to the drive shaft to drive the two adjacent opening / closing members 221 to move synchronously. The power transmission path is simple. Compared to setting the third drive member 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 members 221. Simultaneously, this arrangement facilitates the assembly of the third drive member 222, avoiding the situation where limited operating space hinders assembly efficiency when it is located between the two volute housings 21. It also facilitates maintenance and repair, improving operational efficiency.

[0063] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the second cavity 12 is equipped with at least two dual-outlet fans 2, which are arranged at intervals along the axial direction. 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 ensures adequate airflow coverage and allows for uniform axial airflow distribution, guaranteeing effective airflow circulation. Furthermore, the number of dual-outlet fans 2 that are turned on or off can be controlled to flexibly adjust the airflow volume, improving the adaptability of the air outlet device to different scenarios. Here, "axial" refers to the axial direction of the dual-outlet fans 2.

[0064] 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 first and second radial outlets 211 and 212 of the dual-outlet fan 2. Furthermore, the centrifugal fan has higher static pressure, which helps overcome resistance from duct extension, thereby ensuring air delivery distance and coverage, and reducing the occurrence of reduced airflow due to ductwork configuration.

[0065] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the partition 7 has a connecting port 16 between two adjacent dual-outlet fans 2; the housing 1 has an air inlet 15 between two adjacent dual-outlet fans 2. Thus, the air inlet 15, located between two adjacent dual-outlet fans 2, provides a shared airflow channel for the two fans, allowing airflow entering the second chamber 12 through the air inlet 15 to simultaneously supply both fans in the first air outlet mode. Similarly, the connecting port 16, located between two adjacent fans, provides a shared airflow channel for the two fans, allowing airflow entering the second chamber 12 through the connecting port 16 to simultaneously supply both fans in the second air outlet mode. Therefore, by placing the air inlet 15 and the connecting port 16 between two adjacent dual-outlet fans 2, the airflow is ensured to diffuse evenly within the second chamber 12, guaranteeing sufficient airflow to both fans and preventing localized insufficient airflow.

[0066] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, the partition 7 has a connecting port 16 in the axial direction, located outside the dual-outlet fan 2; the housing 1 has an air inlet 15 in the axial direction, located outside the dual-outlet fan 2. Thus, the connecting port 16 outside the dual-outlet fan 2 can cooperate with the connecting port 16 between two adjacent dual-outlet fans 2, allowing both sides of the dual-outlet fan 2 to draw in airflow in the second air outlet mode, ensuring air intake efficiency. The air inlet 15 outside the dual-outlet fan 2 can cooperate with the air inlet 15 of two adjacent dual-outlet fans 2, allowing both sides of the dual-outlet fan 2 to draw in airflow in the first air outlet mode, ensuring air intake efficiency. Therefore, by providing the connecting port 16 and air inlet 15 outside the dual-outlet fan 2, it is beneficial to drive the airflow in the outer area to participate in circulation, improving air intake efficiency.

[0067] The partition 7 can have at least three connecting ports 16, and the partition 7 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. Thus, with connecting ports 16 on both sides of two adjacent dual-outlet fans 2, airflow can be drawn in from both axial sides of each dual-outlet fan 2 in the second air outlet mode. With air inlets 15 on both sides of two adjacent dual-outlet fans 2, airflow can be drawn in from both axial sides of each dual-outlet fan 2 in the first air outlet mode. This ensures that the airflow drawn in is evenly distributed when two adjacent dual-outlet fans 2 are running simultaneously, avoiding the situation where the air pressure in the middle area is too low if only connecting ports 16 and air inlets 15 are provided on both sides.

[0068] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the connecting port 16 and the air inlet 15 are arranged in pairs. The dual-outlet fan 2 has a fan inlet 23 on at least one side in the axial direction, and at least one pair of connecting ports 16 and air inlets 15 are arranged on the same side as the fan inlet 23. In this way, the connecting port 16 and the air inlet 15 can be set close to the fan inlet 23, so that in the second air outlet mode, the airflow entering the second cavity 12 through the connecting port 16 can directly enter the dual-outlet fan 2 through the fan inlet 23, and in the first air outlet mode, the airflow entering the second cavity 12 through the air inlet 15 can directly enter the dual-outlet fan 2 through the fan inlet 23. This helps to shorten the flow distance of the airflow in the second cavity 12, shorten the airflow intake path, thereby reducing airflow loss and improving the intake efficiency of the first and second air outlet modes.

[0069] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, each of the two adjacent dual-outlet fans 2 has a fan inlet 23 on its adjacent side, and at least one pair of connecting ports 16 and air inlets 15 are provided between the two adjacent fan inlets 23. Thus, the connecting ports 16 between the two adjacent fan inlets 23 can be positioned close to the fan inlets 23 of the two dual-outlet fans 2 on both sides, so as to shorten the airflow path into the second cavity 12 via the connecting ports 16 in the second air outlet mode, thereby improving the air intake efficiency of the second air outlet mode. Similarly, the air inlets 15 between the two adjacent fan inlets 23 can be positioned close to the fan inlets 23 of the two dual-outlet fans 2 on both sides, so as to shorten the airflow path into the second cavity 12 via the air inlets 15 in the first air outlet mode, thereby improving the air intake efficiency of the first air outlet mode.

[0070] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the second 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 the first and second air outlet modes, the air inlet paths of different air outlet modes are isolated, preventing crosstalk caused by mechanical transmission delays during linkage control, where one of the connecting port 16 and the air inlet 15 is not fully closed before the other is open. This helps ensure the stability of the air outlet effect.

[0071] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 2As shown, in the embodiment where the second 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 7 to open or close the connecting port 16. Thus, by driving the first damper 311 to block or open the connecting port 16, the opening and closing of the connecting port 16 can be achieved. This structure is simple, facilitates precise control, and allows for selection of the connection method between the first damper 311 and the partition 7 according to the space and location of the installation scenario, which is beneficial for adapting to the needs of the actual installation scenario. 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. 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. This structure is simple, facilitates precise control. At the same time, the connection method between the second air damper 321 and the housing 1 can be selected according to the space and location of the installation scenario, which is conducive to adapting to the needs of the actual installation scenario.

[0072] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As 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. In this way, 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. This avoids the situation where, due to asynchronous opening and closing of at least two connecting ports 16 or at least two air inlets 15, airflow only enters the second cavity 12 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 outlet.

[0073] Both the partition 7 and the housing 1 are provided with mounting seats. The first connecting rod 313 can be mounted on the partition 7 through the mounting seat to rotatably or movablely connect the first damper 311 to the partition 7. The second connecting rod 323 can be mounted on the housing 1 through the mounting seat to rotatably or movablely connect the second damper 321 to the housing 1.

[0074] In some embodiments, the first drive member 312 can drive at least two first dampers 311 to rotate via the first connecting rod 313. This rotation method, compared to moving at least two first dampers 311, avoids making the size of the housing 1 too large in the direction of movement of the first dampers 311. Similarly, the second drive member 322 can drive at least two second dampers 321 to rotate via the second connecting rod 323. This rotation method, compared to moving at least two second dampers 321, avoids making the size of the housing 1 too large in the direction of movement of the second dampers 321. Similarly, this rotation method, compared to moving at least two second dampers 321, avoids making the size of the housing 1 too large in the direction of movement of the second dampers 321.

[0075] In addition, the motor 4 can be located between two adjacent double-outlet fans 2 so as to drive the two adjacent double-outlet fans 2 to run synchronously. The first damper 311 located between two adjacent double-outlet fans 2 can be provided with a first clearance opening, and the second damper 321 located on the bracket of two adjacent double-outlet fans 2 can be provided with a second clearance opening to avoid the fans and prevent the movement of the first damper 311 and the second damper 321 from interfering with the fans.

[0076] 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, which would cause the size of the housing 1 to be too large in the direction of movement of the first dampers 311, the above-mentioned rotation method is beneficial to reduce the volume of the housing 1.

[0077] 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 with driving at least two first dampers 311 to move, the size of the housing 1 in the direction of movement of the first damper 311 is too large. The above-mentioned rotation method is beneficial to reduce the volume of the housing 1.

[0078] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, a first opening and closing structure 31 is provided on the side of the partition 7 near the second cavity 12. This placement of the first opening and closing structure 31 on the side of the partition 7 near the second cavity 12 avoids the partition 7 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 the first and second 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.

[0079] In some embodiments of this disclosure, reference is made to Figure 5 and Figure 7 As shown, the second opening and closing mechanism 3 is used to close the other of the connecting port 16 and the air inlet 15 when one of them is opened. In this way, the second 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 second opening and closing mechanism 3 and facilitating maintenance and installation.

[0080] In some embodiments of this disclosure, reference is made to Figures 1 to 3 , Figure 5 and Figure 7 As shown, a heat exchanger 5 is provided in the first cavity 11, and a second opening and closing mechanism 3 is provided in the second cavity 12. In this way, when the air outlet device is in the first air outlet mode, the airflow sent to the first cavity 11 through the first air outlet 211 of the dual-air outlet fan 2 can be heat-exchanged by the heat exchanger 5 and then sent out through the first air outlet 14.

[0081] Similarly, when the air outlet device is in the second air outlet mode, the airflow entering the first cavity 11 through the first air outlet 14 can be heated by the heat exchanger 5 and then enter the second cavity 12 through the connecting port 16, so that the dual-outlet fan 2 can draw it in and send it out through the second air outlet 212. Thus, with the heat exchanger 5 located in the first cavity 11, the airflow can be fully heated by the heat exchanger 5 before being sent out when the air outlet device switches between the first and second air outlet modes, thereby achieving temperature regulation of the airflow. By placing the second opening and closing mechanism 3 in the second cavity 12, the air outlet space in the first cavity 11 is avoided from being occupied, preventing the airflow from being blocked by the second opening and closing structure 32 and affecting the air outlet efficiency.

[0082] Among them, such as Figure 2 As shown, a water receiving tray 6 can be installed in the first cavity 11 to collect the condensate generated when the airflow passes through the heat exchanger 5, preventing water from seeping into the internal components such as the motor 4 and circuits, thus affecting the normal operation of the equipment.

[0083] In some embodiments of this disclosure, reference is made to Figures 1 to 9 As shown, the dual-outlet fan 2 is constructed as either a centrifugal fan or a cross-flow fan. The fan casing 21 has a fan inlet 23, which communicates with the air inlet 15. When the dual-outlet fan 2 is constructed as a centrifugal fan, the fan inlet 23 is located on the axial side of the centrifugal fan, i.e., for axial air intake. In this case, the fan inlet 23 can be connected to the air inlet 15 via the second cavity 12, meaning the fan inlet 23 and the air inlet 15 are spaced apart. When the dual-outlet fan 2 is constructed as a cross-flow fan, the fan inlet 23 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 casing 21. In this case, the fan inlet 23 can also be connected to the air inlet 15 via the second cavity 12, meaning the fan inlet 23 and the air inlet 15 are spaced apart.

[0084] 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.

[0085] 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.

[0086] In some embodiments of this disclosure, the air conditioner is configured as a ducted unit. This allows for airflow in different directions when the ducted unit is installed on the ceiling of the room, such as front and bottom airflow, to improve the user experience.

[0087] Below, for reference Figures 1 to 8 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 with front-side 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 cavity 12 from the front, and the second opening and closing structure 32 opens the air inlet 15, allowing external airflow to enter the second cavity 12 through the air inlet 15. The first opening and closing mechanism 22 closes the second air outlet 215, allowing the airflow entering the volute 21 to be sent to the first air outlet 211 through the first air duct 213, and then flow to the first cavity 11 so that the heat exchanger 5 can fully heat the airflow entering the first cavity 11 before blowing it out through the first air outlet 14. Thus, cold air can be prevented from blowing directly onto the human body, and a "canopy" air supply can be formed to improve regional efficiency.

[0088] When heating is required, a second air outlet mode with bottom airflow can be used. Specifically, the second opening and closing structure 32 closes the air inlet 15 to prevent airflow from entering the second cavity 12 from the bottom. The first opening and closing structure 31 opens the connecting port 16, allowing the airflow entering the first cavity 11 through the first air outlet 14 to be fully heated by the heat exchanger 5 before entering the second cavity 12 through the connecting port 16. The first opening and closing mechanism 22 opens the second air outlet 215 and closes the first air outlet 211, allowing the airflow entering the volute 21 to be sent to the second air outlet 212 through the second air duct 214 and then out of the casing 1 through the second air outlet 212. Thus, hot air can be sent to the ground from the bottom air outlet, diffuse along the ground, and slowly rise, forming a "carpet" of airflow to prevent the hot air from rising rapidly and causing low temperatures at lower levels, thus affecting the comfort of the body.

[0089] Therefore, by switching between the first air outlet mode and the second air outlet mode, the switching between "downward air intake and forward air outlet" and "forward air intake and downward air outlet" can be realized, thereby achieving reversible air supply.

[0090] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0091] 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.

[0092] 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.
