That is, when the fresh air door 400 is turned over to the position where the plate surface of the fresh air door 400 is close to the casing 100 around the fresh air opening 114, the fresh air door 400 is located at the completely closed fresh air position. At this time, the fresh outdoor air is completely blocked from entering the first compartment 110, and only the indoor air can enter the first compartment 110 from the air inlet 111.

Illustratively, the cabinet 100 is configured as a rectangular parallelepiped structure including a front side plate 101 and a right side plate. The air inlet 111 is opened in the front side plate 101, and the fresh air inlet 114 is opened in the right side plate. When the fresh air door panel 400 is turned over to the right side plate adjacent to the fresh air opening 114, it is located at the completely closed fresh air position, as shown in fig. 9.

Optionally, the fresh air door panel 400 has a completely avoiding fresh air position; the completely-sheltered fresh air position corresponds to the case 100 in which the panel surface of the fresh air door panel 400 is perpendicular to the periphery of the fresh air opening 114. That is, when the fresh air door panel 400 is turned over to the casing 100 whose panel is perpendicular to the periphery of the fresh air opening 114, the fresh air door panel 400 is located at a position completely avoiding fresh air, and at this time, outdoor fresh air enters the first compartment 110 with the maximum air volume.

Illustratively, the cabinet 100 is configured as a rectangular parallelepiped structure including a front side plate 101 and a right side plate. The air inlet 111 is opened in the front side plate 101, and the fresh air inlet 114 is opened in the right side plate. When the fresh air door panel 400 is turned over to be perpendicular to the right side panel, the fresh air door panel is located at a completely-avoiding fresh air position, as shown in fig. 8.

Optionally, the area of the fresh air door panel 400 is larger than the caliber of the fresh air opening 114, so as to completely close the fresh air opening 114. This is favorable to the fresh air door board 400 to seal the fresh air opening 114 completely, effectively blocks outdoor fresh air from entering the first compartment 110 from the fresh air opening 114.

Optionally, the fresh air door panel 400 is configured as a rectangular plate.

Optionally, the periphery of the fresh air door panel 400 is provided with a sealing rubber strip. Therefore, when the fresh air door panel 400 is turned over to the casing 100 close to the periphery of the fresh air opening 114, the sealing performance can be improved, and outdoor fresh air is prevented from entering the first compartment 110 from the gap between the fresh air door panel 400 and the casing 100.

Optionally, a pipe joint 430 is provided at one side of the fresh air inlet 114 outside the cabinet 100, and the pipe joint 430 is used for connecting an outdoor air pipe. Thus, outdoor fresh air is guided by the outdoor air duct into the first compartment 110 from the fresh air inlet 114.
