Detailed Description
fig. 1 is a schematic structural view of an air outlet device according to an embodiment of the present invention; fig. 2 is a schematic exploded view of an air outlet device according to an embodiment of the present invention. As shown in fig. 1 and 2, an embodiment of the present invention provides an air outlet device for a refrigerator. The air outlet device may include a peripheral wall portion 20, a first axial end portion 30, a second axial end portion 40, and an adjustment portion 50. The peripheral wall 20 is provided with a plurality of first outlets 21, so that at least a part of the airflow entering the air outlet device flows out of the air outlet device from one or more of the plurality of first outlets 21. The first axial end 30 is disposed at one end of the peripheral wall 20, and the first axial end 30 is disposed with at least one second air outlet 31, so that at least a portion of the air flow entering the air outlet device flows out of the air outlet device from one or more of the at least one second air outlet 31. The adjusting portion 50 is rotatably disposed relative to the peripheral wall portion 20 to completely shield, partially shield or completely expose each of the first air outlets 21 at different moving positions, so as to adjust the air outlet area of each of the plurality of first air outlets 21.
In particular, the air flow flowing out via each second outlet mouth 31 has a velocity component flowing in the circumferential direction of the first axial end 30. It can also be said that each second air outlet 31 can be configured such that the air flow flowing out therethrough has a velocity component flowing in the circumferential direction of the first axial end 30, so as to make the air flow flowing out of each second air outlet 31 flow at least in the circumferential direction of the first axial end 30 as much as possible. For example, the air flow exiting each second outlet mouth may be made to have a velocity component flowing in the circumferential direction of the first axial end 30; or the air flow exiting each second outlet may have a circumferential velocity component flowing in the circumferential direction of the first axial end 30 and an axial velocity component flowing in the axial direction of the first axial end 30, the circumferential velocity component being greater than the axial velocity component; or the air flow exiting each second outlet may be made to have a circumferential velocity component flowing in the circumferential direction of the first axial end 30, an axial velocity component flowing in the axial direction of the first axial end 30, and a radial velocity component flowing in the radial direction of the first axial end 30, the circumferential velocity component being greater than the axial velocity component, and the circumferential velocity component being greater than the radial velocity component.
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. The special air outlet mode of the second air outlet 31 is also particularly convenient for the arrangement of the air outlet device in the refrigerator, so that an air duct system in the refrigerator can be simplified, and smooth air flow can be ensured.
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. The fan 60 sucks in an airflow from its axial direction and blows out an airflow in its radial direction so that as much airflow as possible enters the first-stage blowing ports.
In some embodiments of the present invention, the number of the second air outlets 31 is multiple, and the multiple second air outlets 31 are sequentially arranged along the circumferential direction of the first axial end 30, preferably uniformly sequentially arranged. Of course, the plurality of second air outlets 31 may also be unevenly disposed along the circumferential direction of the first axial end 30. Further, the first axial end 30 includes a central portion and a peripheral portion located outside the central portion, and each of the second air outlets 31 is disposed on the peripheral portion for facilitating air outlet. Still further, the fan 60 may be installed at the central portion.
In some embodiments of the present invention, one first air outlet 21 is disposed on a peripheral wall section of the peripheral wall portion 20 between each two adjacent second air outlets 31. The arrangement can fully utilize the airflow entering the housing, ensure the airflow entering the second air outlet 31, ensure smooth air outlet, prevent serious interference of the airflow entering the first air outlet 21 and the second air outlet 31, and prevent bad phenomena such as large noise and the like.
In order to make each second air outlet 31 perform air outlet circumferentially as much as possible, as shown in fig. 1 to 3, an included angle between a plane where each second air outlet 31 is located (i.e. a plane where a mouth edge of each second air outlet 31 is located) and an axis of the peripheral wall portion is 0 ° to 30 °, optionally 0 ° to 15 °, preferably 0 °, 8 °, 12 °, 15 °, and the like. And the axis of each second air outlet 31 (i.e. a line passing through the center of each second air outlet 31 and perpendicular to the plane of the mouth edge of the second air outlet 31) forms an angle of 60 ° to 90 °, optionally 75 ° to 90 °, preferably 80 ° to 90 °, with the radial direction of the first axial end. For example, most preferably, the angle between the plane of each second air outlet 31 and the axis of the peripheral wall portion is 0 °, the angle between the axis of each second air outlet 31 and the radial direction of the first axial end portion is 90 °, that is, the plane of each second air outlet 31 passes through the axis of the peripheral wall portion.
in order to ensure smooth air outlet, the first axial end has at least one guide portion 32 thereon, and each guide portion 32 has: a first guide surface extending from the inner surface of the first axial end to the mouth edge of the inner surface of one of the second air outlets 31 remote from the first axial end, and two second guide surfaces arranged on either side of the first guide surface, respectively, and arranged opposite to each other to define an air flow guide channel for urging the air flow towards the second air outlet. In other embodiments of the present invention, each guide portion 32 may further include a third guide surface disposed opposite the first guide surface.
Further, a projection of the axis of each guide portion 32 in a reference plane perpendicular to the axis of the peripheral wall portion is an arc line coaxial with the peripheral wall portion. Further alternatively, the first guide surface is a slope, and the angle between the plane in which the axis of each guide portion 32 lies and a reference plane perpendicular to the axis of the peripheral wall portion is 2 ° to 45 °, preferably 2 ° to 10 °. Or alternatively, the first guide surface comprises a sloping surface, which may have an angle of 2 ° to 45 °, preferably 2 ° to 10 °, with a reference plane, which connects the sloping surface and the mouth edge of the corresponding second outlet mouth 31.

in particular, the shielding portions 51 may be shielding sheets, and the space, gap or hole between every two adjacent shielding sheets may be the flow portion 52, in particular, when there is only one shielding portion 51, then there is only one corresponding flow portion 52. For example, the regulating portion 50 may include a base portion, a shade sheet provided on the base portion. For another example, the adjusting portion 50 may include a cylinder, and a plurality of flow portions 52 are formed on the cylinder. Both ends of the cylindrical member may be provided with a base portion to improve strength. Further alternatively, the base may be adapted to be rotatably mounted to either the first axial end 30 or the second axial end 40. For example, an annular groove may be provided on the inner surface of the first axial end 30 or the second axial end 40, and an annular protrusion corresponding to the annular groove may be provided on the base to be inserted into the annular groove for rotation. Still alternatively, as shown in fig. 2, the base portion may be rotatably mounted to one end of the peripheral wall portion 20, and when the peripheral wall portion 20 is integrally formed with the first axial end portion 30, the base portion may be rotatably mounted to one end of the peripheral wall portion 20 near the second axial end portion 40.

Further, a motor accommodating part may be provided outside the peripheral wall part 20 to accommodate the motor 70.
In some embodiments of the present invention, as shown in fig. 1 to 3, the number of the first air outlets 21 may be three, and the number of the second air outlets 31 may also be three. The three first outlets 21 may be sequentially spaced in the circumferential direction of the first axial end 30 and in the clockwise direction (based on the line of sight of the observer looking at the first axial end 30 from the second axial end 40). Moreover, the distance between the middle first air outlet 21 and the other two air outlets can be the length of one first air outlet 21. In the adjustment portion 50, the number of the shielding portion 51 and the flow portion 52 is three. The three shielding portions 51 are a first shielding portion, a second shielding portion, and a third shielding portion, respectively. The three flow portions 52 are a first flow portion, a second flow portion, and a third flow portion, respectively. The shielding portion 51 and the flow portion 52 may be sequentially provided at intervals in the circumferential direction of the first axial end portion 30 and in the clockwise direction. The first and second shielding portions are each configured to allow them to completely shield an area of the first outlet 21 of one size. The third shielding portion is configured to allow it to completely shield at least the area of the two sizes of the first air outlets 21, for example, the third shielding portion can shield the area of the two sizes of the first air outlets 21.

The flow portion 52 between the third shield portion and the first shield portion is a third flow portion. When the air conditioner works, the adjusting part 50 rotates to enable different first air outlets 21 to be in an open state, for example, when the first shielding part shields the first air outlet 21 in the middle, the other two first air outlets 21 can be in an open state; for another example, when the second shielding portion shields the first air outlet 21 in the middle, the other two first air outlets 21 can be both in a closed state.
In some alternative embodiments of the present invention, in some specific embodiments of the present invention, the number of the first air outlets 21 may be three, and the number of the second air outlets 31 may also be three.
