In this embodiment, the plurality of first air outlets 21 may be air outlets of one level, and the at least one second air outlet 31 may be air outlets of another level, so as to achieve different air supply requirements. For example, in some embodiments, the first air outlets 21 can supply air to a plurality of portions of the freezing chamber, and the second air outlet 31 can supply air to the refrigerating chamber, and particularly, the adjusting portion 50 can adjust the air supply amount of the freezing chamber at the plurality of portions, and can supply air to the refrigerating chamber through another level of air outlet while ensuring the air amount requirement in the refrigerating chamber, thereby not only ensuring the requirement of cooling capacity in the refrigerating chamber, but also adjusting the temperature of a plurality of different portions in the refrigerating chamber in real time, ensuring no loss of food nutrients, reducing power consumption, and saving energy.
In some embodiments of the invention, the peripheral wall portion 20 is preferably cylindrical, and may be integrally formed with one of the first and second axial ends 30, 40, the other of which may be snapped into the peripheral wall portion 20. The integral structure of the peripheral wall portion 20, the first axial end portion 30 and the second axial end portion 40 may also be referred to as a housing of the air outlet device. The regulating portion 50 may be preferentially mounted inside the peripheral wall portion 20, i.e., inside the housing. One or more air inlets may be formed in the second axial end 40.
In some embodiments of the present invention, the air outlet device may further include a blower 60 configured to promote airflow from the one or more air inlets into the peripheral wall portion 20. Preferably, the fan 60 is a centrifugal fan or a centrifugal impeller, which may also be referred to as a centrifugal impeller.

In order to make each second outlet 31 perform axial outlet as much as possible, i.e. each second outlet 31 is configured to axially outlet air, the peripheral portion may be configured to include a flat plate portion and at least one guide portion 32. The flat plate portion is provided with at least one second air outlet 31. Further, in some embodiments, each guide portion 32 extends obliquely from an edge of one second air outlet 31 adjacent to the peripheral wall portion 20 towards the inside of the first axial end 30 and towards the axis of the peripheral wall portion 20. The guide part 32 may have a plate shape and may also be referred to as a guide plate. Further, both ends of each guide portion 32 may also be provided with guide shielding plates. In other embodiments, as shown in fig. 3, each guiding portion 32 extends obliquely from an edge of one second air outlet 31 away from the peripheral wall portion 20 to the outside of the first axial end 30 and in a direction away from the axis of the peripheral wall portion 20.
