[0032] The present embodiment provides an air outlet structure capable of not affecting the air outlet area and having high aesthetic degree, for opening and closing the air outlet 11.

[0033] As Figures 1-5As shown, a specific embodiment of an air outlet structure provided by the embodiment includes a mask 1, a baffle 2, and a retracting mechanism. The mask 1 is provided with an air outlet 11. The mask 1 is used to be mounted on a device host. A receiving space is formed between the mask 1 and the device host. The baffle 2 is movably arranged at the air outlet 11 of the mask 1. The retracting mechanism is arranged on the mask 1 and connected with the baffle 2. The baffle 2 has an open state. The retracting mechanism drives the baffle 2 to retract towards the inner side of the mask 1, and the baffle 2 is located in the receiving space. The baffle 2 has a closed state. The retracting mechanism drives the baffle 2 to extend towards the outer side of the mask 1 and embed in the air outlet 11. The bottom surface of the baffle 2 is flush with the outer surface of the mask 1.

[0034] In use, the mask 1 is mounted on the device host, air supply is performed through the air outlet 11, and the baffle 2 can realize opening and closing of the air outlet 11 through the retracting mechanism. In the open state of the baffle 2, the retracting mechanism drives the baffle 2 to move to the receiving space between the mask 1 and the device host. The air outlet 11 is opened, and the baffle 2 does not block the air outlet 11, which does not affect the actual air outlet area of the air outlet 11. In the closed state of the baffle 2, the retracting mechanism drives the baffle 2 to move to the air outlet 11, so that the air outlet 11 is closed, and the bottom surface of the baffle 2 is flush with the outer surface of the mask 1, improving the aesthetic appearance. The air outlet structure provided by the embodiment solves the problem that the air outlet 11 is provided with a swing leaf in the prior art, which reduces the air outlet area.

[0035] It should be explained that, in the embodiment, the mask 1 is horizontally arranged as an example. The movement of the baffle 2 is divided into two ends, which are vertical movement and horizontal movement. The vertical movement is used to make the baffle 2 press against or leave the air outlet 11 on the mask 1. The horizontal movement is used to make the baffle 2 retract or extend into the receiving space. In actual use, the arrangement direction of the mask 1 can be adjusted according to the design requirements of the use environment of the household appliance 31.

[0036] As shown in FIG. 1, Figures 1-6As shown, the air outlet structure provided by the embodiment includes a driving device 3, a support assembly 4 and a top edge assembly 5.

In the closed state of the baffle 2, the second end of the baffle 2 abuts against the top edge assembly 5. In the open state of the baffle 2, the driving device 3 drives the baffle 2 to move towards the storage space. When the first end of the baffle 2 contacts the support assembly 4, the support assembly 4 stops the baffle 2. The support rod 6 rotates relative to the baffle 2, so that the movement of the baffle 2 along the extension direction of the mask 1 is converted into the movement along the direction perpendicular to the mask 1, i.e. the horizontal movement is converted into the vertical movement. The baffle 2 can be retracted into the storage space above the support assembly 4. In the closed state of the baffle 2, the driving device 3 drives the baffle 2 to move away from the storage space. When the second end of the baffle 2 contacts the top edge assembly 5, the top edge assembly 5 stops the baffle 2. The movement of the baffle 2 along the extension direction of the mask 1 is converted into the movement along the direction perpendicular to the mask 1, i.e. the horizontal movement is converted into the vertical movement, so that the baffle 2 can be embedded into the air outlet 11 to be closed. The bottom surface of the baffle 2 is flush with the outer surface of the mask 1, which increases the aesthetic appearance. In addition, as an alternative embodiment, the retraction mechanism can also include a horizontal driving mechanism and a vertical driving mechanism.

The baffle 2 can be retracted into the storage space above the support assembly 4, and the supporting portion 42 supports the baffle 2 in the storage space, thereby improving the stability of the baffle 2. Specifically, the supporting portion 42 is arranged in a plate structure, and two supporting portions 42 are arranged along the length direction of the abutting portion 41.
