For a further understanding of the nature, features, and efficacy of the present utility model, the following examples are set forth in order to provide a further understanding of the utility model, and are intended to be described in connection with the accompanying drawings:

the kitchen air conditioner has heavier oil smoke in the running environment, and when the kitchen air conditioner runs, the air supply port of the kitchen air conditioner supplies air to the kitchen, so that the air supply port of the kitchen air conditioner has outward flowing air flow, and the oil smoke in the kitchen cannot enter the internal air duct of the kitchen air conditioner through the air supply port of the kitchen air conditioner. However, in winter or in seasons with proper temperature, when the kitchen air conditioner is not required to be operated, at this time, the air supply port of the kitchen air conditioner has no airflow flowing outwards, at this time, if a user cooks in the kitchen, the oil smoke in the kitchen easily enters the internal air passage of the kitchen air conditioner through the air supply port of the kitchen air conditioner, after the oil smoke enters the internal air passage of the kitchen air conditioner through the air supply port of the kitchen air conditioner for a long time, certain oil dirt can be accumulated in the internal air passage of the kitchen air conditioner, and the air passage of the kitchen air conditioner is difficult to clean. If the air outlet device is arranged at the air outlet of the kitchen air conditioner, the air blown out from the air outlet of the kitchen air conditioner firstly enters the air outlet device and then is blown out by the air outlet device, and the air outlet of the air outlet device can be completely closed when the kitchen air conditioner does not operate, so that the oil smoke in the kitchen can be prevented from entering the internal air duct of the kitchen air conditioner.

According to the air outlet switch door assembly, the air outlet 11 can be in a completely closed state and a completely opened state, and after the air outlet switch door assembly is connected to the air outlet of the kitchen air conditioner, the air outlet 11 of the air outlet switch door assembly is completely opened when the kitchen air conditioner operates, so that air flow output by the air outlet of the kitchen air conditioner can enter the air outlet switch door assembly and be blown out by the air outlet 11 of the air outlet switch door assembly, when the kitchen air conditioner stops operating, the air outlet 11 of the air outlet switch door assembly is completely closed, and oil smoke in a kitchen cannot enter an air duct of the air outlet switch door assembly through the air outlet 11 of the air outlet switch door assembly, so that the oil smoke in the kitchen cannot enter an inner air duct of the kitchen air conditioner through the air outlet switch door assembly. Referring to fig. 1 to 7, the air outlet door opening and closing assembly of the present utility model includes a panel 1, a moving plate 2, a guide vane assembly 3 and a driving device 4, wherein the panel 1 has an air outlet 11, the moving plate 2 has an air guiding opening 21, an appearance surface 22 and a non-appearance surface, the moving plate 2 has a first state in which the air guiding opening 21 is aligned with the air outlet 11 and a second state in which the appearance surface 22 shields the air outlet 11, the guide vane assembly 3 has an air inlet end and an air guiding end, when the moving plate 2 is in the first state, the air guiding end of the guide vane assembly 3 is aligned with the air outlet 11 and passes downward over the panel 1, when the moving plate 2 is in the second state, the guide vane assembly 3 rotates to a position in which the guide vane assembly 2 does not interfere with the moving plate 2, and the driving device 4 is used for driving the moving plate 2 to rotate around an axis passing through the center thereof and switch between the first state and the second state. It should be understood that the area other than the air outlet 11 on the upper surface of the panel 1 forms a shielding area for the panel 1, the area other than the air guide 21 and the appearance surface 22 on the lower surface of the movable plate 2 forms a non-appearance surface of the movable plate 2, and the shape and size of the appearance surface 22 on the movable plate 2 are adapted to the shape and size of the air outlet 11 on the panel 1. When the air outlet switch door assembly is used on a kitchen air conditioner, if the kitchen air conditioner is in an operation state, the movable plate 2 is in a first state, the air guide opening 21 of the movable plate 2 is aligned with the air outlet 11 of the panel 1, the appearance surface 22 and the non-appearance surface on the movable plate 2 are both shielded by a shielding area on the panel 1, meanwhile, the air inlet end of the guide vane assembly 3 is aligned with the air outlet 11 and passes through the panel 1 downwards, the air flow output by the air outlet of the kitchen air conditioner enters the guide vane assembly 3, flows into the air guide end from the air inlet end of the guide vane assembly 3, and finally is blown out from the air guide end; when the kitchen air conditioner stops running, because the front air guide end of the guide vane assembly 3 downwards passes through the panel 1, in order to avoid the guide vane assembly 3 interfering with the sliding of the movable plate 2, the guide vane assembly 3 rotates to a position which is not interfered with the movable plate 2 before the movable plate 2 starts rotating, wherein the non-interference position means that when the non-appearance surface of the movable plate 2 and the appearance surface 22 slide above the air outlet 11 of the panel 1, the guide vane assembly 3 cannot interfere with the movable plate 2, that is, the height of the lowest point of the guide vane assembly 3 is greater than the height of the highest point of the upper surface of the movable plate 2, then the driving device 4 drives the movable plate 2, the movable plate 2 rotates around the axis passing through the center of the movable plate 2, and is switched from the first state to the second state, after the movable plate 2 is switched to the second state, the air guide opening 21 on the movable plate 2 is shielded by the shielding area on the panel 1, the appearance surface 22 on the movable plate 2 shields the air outlet 11 on the panel 1, and the oil smoke in the kitchen air conditioner cannot enter the air outlet opening and closing assembly through the air outlet 11 on the panel 1, and cannot enter the kitchen air conditioner door opening and closing assembly through the air outlet and cannot enter the kitchen air conditioner door opening and closing assembly. According to the air outlet switch door assembly, the movable plate 2 is arranged above the panel 1, when the driving device 4 drives the movable plate 2, the movable plate 2 rotates around the axis passing through the center of the movable plate 2 to enable the movable plate 2 to be switched between the first state and the second state, when the movable plate 2 is in the first state, the air guide opening 21 on the movable plate 2 is aligned with the air outlet 11 on the panel 1, the air guide end of the guide vane assembly 3 is aligned with the air outlet 11 and downwards passes through the panel 1, the air supply requirement can be met, after the guide vane assembly 3 rotates to a position which is not interfered with the movable plate 2, the movable plate 2 can rotate and switch to the second state under the driving of the driving device 4, and the appearance surface 22 shields the air outlet 11, at the moment, because the movable plate 2 is tightly attached to the panel 1, oil smoke in a use environment cannot enter from a gap between the movable plate 2 and the panel 1, when the air outlet switch door assembly is used on a kitchen air conditioner, the oil smoke cannot enter the kitchen air conditioner through the air outlet switch assembly, the oil smoke cannot enter the kitchen air conditioner, and the kitchen air conditioner can keep the kitchen air conditioner clean, and the oil smoke can be accumulated in the kitchen air conditioner.

In the air outlet door opening and closing assembly of the embodiment, the movable plate 2 further has a third state, and in the third state, the guide vane assembly 3 rotates to a position not interfering with the movable plate 2, and part of the non-appearance surface slides from the air outlet 11 to be exposed as a temporary appearance surface.
