[0032] According to the technical solution of the present embodiment, an upper air vent 11 is provided on the upper part of the housing 10 of the cabinet air conditioner, a lower air vent 12 is provided on the lower part, and a filtering device is provided. The cabinet air conditioner has an upper air outlet mode and a lower air outlet mode. When in use, it can be switched to the upper air vent 11 to outlet air and the lower air vent 12 to inlet air, or the upper air vent 11 to inlet air and the lower air vent 12 to outlet air, so as to meet different use requirements. For example, the upper air vent 11 outlets air during cooling, and the lower air vent 12 outlets air during heating, so that the cold air with high density flows from top to bottom or the hot air with low density flows from bottom to top, so as to facilitate the uniform distribution of indoor temperature and improve the comfort of users. Moreover, through the filtering device, the upper air vent 11 can be covered to filter the gas entering the upper air vent 11 when the upper air vent 11 inlets air, and the lower air vent 12 can be covered to filter the gas entering the lower air vent 12 when the lower air vent 12 inlets air, so as to adapt to the change of the air outlet mode and ensure the cleanliness of the gas entering the air conditioner.

[0033] In this embodiment, a fan is disposed in the housing 10, and the fan can change the wind direction, so that the upper air outlet mode and the lower air outlet mode can be switched by changing the wind direction of the fan.

[0034] In this embodiment, the filter device includes: a first filter mechanism 20, which is arranged at the upper part of the housing 10, and the first filter mechanism 20 has a movable first filter 21, and the first filter 21 can cover or avoid the upper air outlet 11 by changing its position; a second filter mechanism 30, which is arranged at the lower part of the housing 10, and the second filter mechanism 30 has a movable second filter, and the second filter can cover or avoid the lower air outlet 12 by changing its position; when the cabinet air conditioner is in the upper air outlet mode, the first filter 21 avoids the upper air outlet 11, and the second filter covers the lower air outlet 12; when the cabinet air conditioner is in the lower air outlet mode, the first filter 21 covers the upper air outlet 11, and the second filter avoids the lower air outlet 12.

[0037] like Figures 3 to 5 As shown, there is a bending position on the extension path of the first guide groove, and the first filter screen 21 is a bendable structure so as to pass through the bending position of the first guide groove during the movement. The bending position is set on the extension path of the first guide groove to facilitate matching with the internal structure of the housing 10. The first filter screen 21 is set as a bendable structure, which can be bent and deformed, so that it can change direction in the first guide groove. The first filter screen 21 can use a plastic material as a support frame, and a metal mesh is set on the support frame for filtering.
