Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air treatment equipment, and in particular to an air duct unit. Background Art
[0002] Typically, an air conditioner indoor unit includes at least two air vents: one for outlet air only and the other for return air only. The airflow is directed between the two vents by the rotation of the fan within the unit. As people's pursuit of air conditioning comfort continues to increase, indoor units need to switch the airflow direction based on the operating mode. However, due to the directional requirements of the fan blades, reversing the motor that drives the blades makes it difficult to reverse the airflow direction, making it impossible to adjust the airflow direction. This results in a single airflow direction, making it difficult to meet the diverse needs of users.
[0003] In some solutions, a rotatable fan is provided, allowing the fan to rotate 180° within the air conditioner's indoor unit, thereby achieving reverse airflow. However, due to the limited space inside the housing, these solutions can easily interfere with the housing during the fan's rotation, thus affecting the fan's performance. Therefore, how to prevent the fan from interfering with the housing during rotation is an urgent problem to be solved in this field. Summary of the Invention
[0004] The invention discloses a duct fan, which solves the problem in the prior art that the fan easily interferes with the shell during the turning process.

During the process of the fan changing the air outlet direction, the shielding component opens the avoidance opening, and the avoidance opening is used to provide a reversing space for the fan during the process of changing the air outlet direction.
[0006] Furthermore, the avoidance opening is arranged below the fan.
[0007] Furthermore, the duct unit further comprises: a limiting member, which is provided on the housing and cooperates with the blocking member in a limiting manner when the blocking member is in the closed position.
[0008] Furthermore, the free end of the shielding component has a limiting folded edge, and when the shielding component is in the closed position, the limiting folded edge is in limiting cooperation with the limiting member.

[0010] Furthermore, the limiting member is a magnet, and when the shielding member is in the closed position, the limiting member limits the shielding member by magnetic force.
[0011] Furthermore, when the shielding component is in the closed position, a sealing structure is provided between the shielding component and the housing.
[0012] Furthermore, the duct unit further includes a driving device, which is drivingly connected to the shielding component.
[0013] Furthermore, a downwind port and a side wind port are provided on the shell, and the fan has a first direction and a second direction; when the duct air conditioner is in cooling mode, the fan is in the first direction, the downwind port takes in air and the side wind port discharges air; when the duct air conditioner is in heating mode, the fan is in the second direction, the side wind port takes in air and the downwind port discharges air.
[0014] Furthermore, the fan is any one of a cross-flow fan, a centrifugal fan, a mixed-flow fan and an axial-flow fan.

[0019] The present invention will be further described below with reference to the embodiments, but is not limited to the contents of the description.
[0020] like Figure 1 and Figure 2The embodiment of the present invention shown discloses a duct fan, comprising a fan 10, a housing 20, and a shielding member 30. The fan 10 is movably arranged to change the direction of the air outlet by moving. The fan 10 is arranged in the housing 20, and the housing 20 is provided with a avoidance opening 21, which is located at the position of the fan 10. The shielding member 30 is rotatably arranged on the housing 20. The shielding member 30 opens or closes the avoidance opening 21 by rotating. When the fan 10 changes the direction of the air outlet, the shielding member 30 opens the avoidance opening 21. The avoidance opening 21 is used to provide a reversing space for the fan 10 during the process of changing the air outlet direction. When the fan 10 needs to change its direction, the shielding member 30 rotates to open the avoidance opening 21, providing the reversing space required for the fan 10 to change the air outlet direction, thereby avoiding interference between the fan 10 and the housing 20 during the reversing process, thereby achieving reversing of the fan 10.
[0021] The duct fan of the present invention is provided with a avoidance opening 21 and a shielding component 30. The avoidance opening 21 can be opened or closed by rotating the shielding component 30. When the fan 10 needs to reverse, the avoidance opening 21 is opened, and the reversing space is provided by the avoidance opening 21 to realize the reversal of the fan 10; during normal operation, the avoidance opening 21 is closed, thereby making the appearance more beautiful and avoiding air leakage.
[0022] It should be noted that the avoidance opening 21 is provided below the fan 10. When the avoidance opening 21 is opened, the housing 20 is connected to the outside through the avoidance opening 21, and a portion of the structure of the fan 10 can extend outside the housing 20 through the avoidance opening 21 during the reversing process, thereby avoiding interference with the housing 20.
[0023] The duct air conditioner further includes a stopper 40, which is disposed on the housing 20 and engages with the shielding member 30 in a closed position. The stopper 40 allows the stopper 40 to engage with the stopper 40 when the shielding member 30 is closed, thereby ensuring that the shielding member 30 reliably closes the escape opening 21.
[0024] It should be noted that there are various ways to cooperate with each other in limiting the blocking component 30 and the limiting component 40, for example, they can cooperate with each other through a pin and a pin hole, or through magnetic limiting cooperation.
[0025] In this embodiment, the shielding member 30 and the stopper 40 are secured in position by means of a pin and a pinhole. Specifically, the shielding member 30 is a cover plate, one end of which is pivotally connected to the housing 20 and the other end is free. The free end of the shielding member 30 has a stopper fold 31, which engages with the stopper 40 in a closed position.
[0026] It should be noted that the pin can be elastically contracted, and the free end of the pin has a guide surface. When subjected to external force in the horizontal direction, the pin can be Figure 1 and Figure 2 When the shielding member 30 is moved to the closed position, the retaining edge 31 contacts the guide surface of the pin, causing the pin to retract to the right. When the pin aligns with the pin hole, it returns to the pin hole, thus achieving a retaining fit. To open the shielding member 30, the pin is first released. An external force can then be applied to move the pin to the right again, causing it to retract and disengage from the pin hole.
[0027] Preferably, a pin hole is provided on the limiting folding edge 31, and the limiting member 40 is a pin, which is inserted into the pin hole to form a limiting fit.
[0028] In an embodiment not shown in the figure, its structure is basically the same as the above embodiment, with the only difference being that the limiting member 40 is a magnet, and when the shielding member 30 is in the closed position, the limiting member 40 limits the shielding member 30 by magnetic force.
[0029] To improve the sealing effect and prevent air leakage from the housing 20, a sealing structure 50 is provided between the shielding member 30 and the housing 20 when the shielding member 30 is in the closed position. Preferably, the sealing structure is a rubber pad. When the shielding member 30 is closed, the shielding member 30 applies a force to the rubber pad. Under the action of the external force, the rubber pad deforms and fills the gap between the shielding member 30 and the housing 20, thereby achieving sealing.
[0030] The duct machine also includes a driving device, which is drivingly connected to the shielding component 30. By providing the driving device, the shielding component 30 can be automatically opened and closed, which is convenient for operation.
[0031] A downwind port 22 and a side wind port 23 are provided on the shell 20, and the fan 10 has a first orientation and a second orientation; when the duct air conditioner is in cooling mode, the fan 10 is in the first orientation, the downwind port 22 takes in air and the side wind port 23 discharges air; when the duct air conditioner is in heating mode, the fan 10 is in the second orientation, the side wind port 23 takes in air and the downwind port 22 discharges air.
[0032] It should be noted that the fan 10 is any one of a cross-flow fan 10 , a centrifugal fan 10 , a mixed-flow fan 10 and an axial-flow fan 10 .
[0033] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not possible to enumerate all embodiments here. Any obvious variations or modifications arising from the technical solution of the present invention remain within the scope of protection of the present invention.
