[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] Combination Figure 1-4 As shown, an embodiment of the present disclosure provides a refrigerator, including a fan 1, an air duct cover 2, a fan cover 3 and a shielding member 4.

[0043] like Figure 1-3 As shown, the air duct cover plate 2 is arranged on the rear side wall of the first chamber, and is provided with an air supply port 21 connected to the first chamber; the fan 1 is arranged outside the first chamber and is located at the rear side of the air duct cover plate 2; the fan cover 3 is arranged on the fan 1, and is provided with a first air outlet 31, and the first air outlet 31 is arranged opposite to the air duct cover plate 2; the shielding member 4 is movably arranged at the first air outlet 31, and is configured to controllably shield the first air outlet 31 to adjust the air outlet area of ​​the first air outlet 31; wherein the airflow generated by the fan 1 flows into the first chamber through the first air outlet 31 and the air supply port 21 in sequence.

[0044] In the refrigerator provided by the embodiment of the present disclosure, the fan 1 is covered by a fan cover 3, and the fan cover 3 is provided with a first air outlet 31. The airflow generated by the fan 1 is blown out of the fan cover 3 through the first air outlet 31 and blown toward the first chamber. The shielding member 4 is movably provided at the first air outlet 31, and the air outlet area of ​​the first air outlet 31 can be adjusted by controlling the shielding area of ​​the first air outlet 31 by the shielding member 4, so that the air volume of the first air outlet 31 can be adjusted according to the needs of the user. Moreover, the first air outlet 31 of the fan cover 3 is arranged opposite to the air duct cover plate 2, and the air duct cover plate 2 is provided with an air supply port 21 connected to the first chamber. After the airflow of the fan 1 is blown out of the fan cover 3 through the first air outlet 31, it can be directly blown toward the air duct cover plate 2 and sent into the first chamber through the air supply port 21, thereby shortening the air path and improving the circulation efficiency.

[0045] The shielding member 4 can be movably arranged at the first air outlet 31 to shield the first air outlet 31 so as to adjust the air outlet area of ​​the first air outlet 31. It can be understood that the shielding member 4 can be arranged in the fan cover 3, fit with the first air outlet 31 provided in the fan cover 3, to shield the first air outlet 31, and move relative to the first air outlet 31 to adjust the air outlet area of ​​the first air outlet 31. The shielding member 4 can also be arranged outside the fan cover 3, fit with the first air outlet 31 provided in the fan cover 3, to shield the first air outlet 31, and move relative to the first air outlet 31 to adjust the air outlet area of ​​the first air outlet 31. The present application takes the shielding member 4 being arranged in the fan cover 3 and fitting with the first air outlet 31 as an example.

[0046] Alternatively, if Figure 2 and Figure 3 As shown, the first air outlet 31 and the air supply outlet 21 are staggered.

[0047] When setting the first air outlet 31 of the fan cover 3 and the air supply port 21 of the air duct cover 2, the first air outlet 31 and the air supply port 21 are staggered to avoid the first air outlet 31 and the air supply port 21 being arranged opposite to each other, to avoid the airflow in the first chamber entering the air duct from the air supply port 21, and directly flowing to the first air outlet 31 and entering the fan cover 3, to avoid external airflow interfering with the normal operation of the fan 1.

[0048] like Figure 3 As shown, optionally, there are multiple air supply ports 21 , and they are arranged corresponding to the outer peripheral side of the first air outlet 31 .

[0049] The airflow generated by the fan 1 is used to adjust the temperature of the first chamber. Therefore, the airflow generated by the fan 1 is blown out from the first air outlet 31 of the fan cover 3 and blown toward the oppositely arranged air duct cover 2. The air supply port 21 opened on the air duct cover 2 connects the first chamber and the inside of the air duct. The airflow generated by the fan 1 enters the first chamber through the air supply port 21.

[0050] When there are multiple air supply ports 21 and they are arranged corresponding to the outer peripheral side of the first air outlet 31, the coverage area of ​​the multiple air supply ports 21 surrounds the first air outlet 31 inside. No matter which direction the airflow of the first air outlet 31 blows to, the airflow blown out from each direction can flow to the air supply ports 21 in time, ensuring that the airflow in each direction is provided with a corresponding air supply port 21, so that the air can be sent into the first room as soon as possible to adjust the temperature of the first room.

[0051] Alternatively, if Figure 2 As shown, the fan cover 3 includes an end surface portion 33 , and the end surface portion 33 is arranged perpendicular to the rotation axis of the fan 1 ; wherein the first air outlet 31 is arranged on the end surface portion 33 .

[0052] The end face portion 33 of the fan cover 3 is arranged perpendicularly to the rotating shaft of the fan 1, the first air outlet 31 is arranged on the end face portion 33, and the first air outlet 31 is arranged opposite to the air duct cover plate 2, therefore, the end face portion 33 of the fan cover 3 is arranged opposite to the air duct cover plate 2. Multiple air supply ports 21 are arranged corresponding to the outer peripheral side of the first air outlet 31, and the range of the multiple air supply ports 21 surrounds the multiple first air outlets 31 inside. The airflows of the multiple first air outlets 31 blow to multiple directions, but the airflows blown out from each direction can flow to the adjacent air supply ports 21 in time, ensuring that the airflows in each direction are provided with corresponding air supply ports 21 to flow, and the airflow flows from the first air outlet 31 to the air supply port 21 within the relatively shortest path and time, so that the airflow can be sent to the first chamber as soon as possible, and the temperature of the first chamber can be adjusted more quickly, thereby improving the adjustment efficiency.

[0053] Alternatively, if Figure 2As shown, there are multiple first air outlets 31 , and the multiple first air outlets 31 are evenly distributed on the end surface portion 33 of the fan cover 3 in the circumferential direction.

[0054] The above embodiment mentioned that the shielding member 4 can be movably arranged at the first air outlet 31, so as to shield the first air outlet 31, and then adjust the air outlet area of ​​the first air outlet 31 by changing the shielding area. When there are multiple first air outlets 31, the multiple first air outlets 31 are evenly distributed circumferentially on the end surface portion 33 of the fan cover 3. The number of the first air outlets 31 is multiple, which increases the total area of ​​the first air outlets 31. The airflow of the fan 1 has a wider range when blowing out of the fan cover 3, and the area of ​​the fan cover 3 on the side facing the air duct cover 2 can be fully utilized, and the air outlet area can be controlled more accurately.

[0055] The circumferential distribution can make the distribution of the first air outlet 31 correspond to the blowing area of ​​the fan 1, so that the airflow generated by the fan 1 in all directions can be blown out of the fan cover 3 as much as possible. The uniform distribution can make the airflow of the fan 1 more evenly dispersed when it is blown out of the fan cover 3 by the fan 1.

[0056] Alternatively, if Figure 1 As shown, there are multiple first air outlets 31 , and the shielding member 4 includes multiple shielding portions 41 , each shielding portion 41 is arranged corresponding to a corresponding first air outlet 31 .

[0057] The plurality of first air outlets 31 are evenly distributed on the fan cover 3 in the circumferential direction and are arranged opposite to the air duct cover plate 2. The shielding member 4 is movably arranged at the first air outlet 31. The shielding member 4 includes a plurality of shielding parts 41. The plurality of shielding parts 41 and the plurality of first air outlets 31 are arranged one by one. Each shielding part 41 is arranged corresponding to the corresponding first air outlet 31. In this way, one shielding part 41 controls one first air outlet 31, so that the air outlet area of ​​the first air outlet 31 can be controlled more accurately. The plurality of shielding parts 41 can be integrally formed as the shielding member 4 as a whole, and the plurality of shielding parts 41 can also be independent individuals that can move relatively independently. When the plurality of shielding parts 41 can move independently, the area of ​​each or a certain first air outlet 31 can be controlled, so that the air outlet area of ​​the first air outlet 31 can be adjusted in a wider range, and the air outlet area can be controlled more flexibly, so that the temperature of the refrigerator compartment can be better adjusted.

[0058] Alternatively, if Figure 1 As shown, the fan cover 3 is provided with a rotating shaft 32 , and the shielding member 4 is rotatably connected to the rotating shaft 32 to adjust the shielding area of ​​the first air outlet 31 .

[0059] The shielding member 4 is arranged in the fan cover 3, is arranged relative to the first air outlet 31, and can move relative to the first air outlet 31. The fan cover 3 is provided with a rotating shaft 32. The shielding member 4 is connected to the rotating shaft 32 and can rotate relative to the rotating shaft 32, relative to the fan cover 3, and relative to the first air outlet 31. During the rotation, the shielding area of ​​the first air outlet 31 by the shielding member 4 changes, thereby adjusting the air outlet area of ​​the first air outlet 31.

[0060] It can be understood that the fan cover 3 can also be provided with a slide groove, and the shielding member 4 can be provided with a sliding portion, which can slide relative to the fan cover 3 in the slide groove. During the sliding process, the shielding area of ​​the first air outlet 31 by the shielding member 4 changes, thereby adjusting the air outlet area of ​​the first air outlet 31.

[0061] Alternatively, if Figure 1 As shown, a plurality of shielding portions 41 intersect at the rotating shaft 32 and are evenly connected to the rotating shaft 32 in the circumferential direction.

[0062] The above embodiment mentioned that the shielding member 4 includes a plurality of shielding parts 41, and when the plurality of shielding parts 41 can be integrally formed and serve as the shielding member 4 as a whole, the plurality of shielding parts 41 intersect at the rotating shaft 32, and the intersection is connected to the rotating shaft 32 and the connection can rotate relative to the rotating shaft 32. Moreover, the plurality of shielding parts 41 are evenly connected to the rotating shaft 32 in the circumferential direction, and the above embodiment mentioned that the plurality of first air outlets 31 are evenly distributed in the circumferential direction on the fan cover 3, the plurality of shielding parts 41 are arranged relative to the plurality of first air outlets 31, and the plurality of shielding parts 41 can simultaneously rotate relative to the correspondingly arranged first air outlets 31.

[0063] The shielding member 4 includes a plurality of shielding parts 41, and the plurality of shielding parts 41 can move relatively independently, and the plurality of shielding parts 41 intersect at the rotating shaft 32. A connection is provided between each shielding part 41 and the rotating shaft 32, and the plurality of shielding parts 41 are evenly connected to the rotating shaft 32 in the circumferential direction. In this way, according to user needs, two, four or more shielding parts 41 evenly connected to the rotating shaft 32 in the circumferential direction can be rotated along the rotating shaft 32 relative to the first air outlet 31.

[0064] like Figure 1 and Figure 2As shown, the shielding portion 41 is fan-shaped, the centers of the multiple fans intersect at the rotating shaft, and the outer arc extends away from the center. The radius and arc length of the fan are related to the position and size of the first air outlet. The first air outlet 31 is fan-shaped, the outer arc length of the fan-shaped is slightly larger than the arc length of the fan, the radius corresponding to the outer arc length is slightly larger than the radius corresponding to the fan, the inner arc length is smaller than the outer arc length, and the inner arc length and the radius corresponding to the inner arc length are related to the area of ​​the first air outlet 31. When the user needs each or a certain first air outlet 31 to have a larger area, the inner arc length and radius can be smaller, so that the inner arc is closer to the center of the fan. When the user needs each or a certain first air outlet 31 to have a smaller area, the inner arc length and radius can be larger, so that the inner arc is closer to the outer arc, or the outer arc length and radius are smaller, and the arc length and radius of the fan of the corresponding shielding portion 41 are correspondingly reduced. In this way, the position and size of the shielding portion 41 and the first air outlet 31 can be set according to user needs, and some costs can be reduced to a certain extent.

[0065] Alternatively, if Figure 1 As shown, the rotating shaft 32 of the fan cover 3 is arranged opposite to the axis of the rotating shaft of the fan 1 .

[0066] A plurality of first air outlets 31 are evenly arranged on the fan cover 3 in the circumferential direction, and a plurality of shielding parts 41 are arranged relative to the plurality of first air outlets 31 and are evenly connected to the rotating shaft 32 in the circumferential direction. When the axial position of the rotating shaft 32 is the same as the position of the central axis of the fan of the fan 1, the distance from the rotating shaft 32 to each first air outlet 31 is the same, so that the length of each shielding part 41 is the same, and therefore the size and shape of each shielding part 41 can be the same, which reduces the difficulty of the manufacturing process of the shielding member 4. Since the size and shape of each shielding part 41 are the same, the size and shape of the plurality of first air outlets 31 can also be the same, which reduces the difficulty of the manufacturing process of the first air outlet 31 and reduces the production cost. In addition, the size and shape of the plurality of shielding parts 41 and the plurality of first air outlets 31 are respectively the same, which makes it more accurate to adjust the air outlet area according to demand.

[0067] Optionally, the refrigerator further includes a controller, which is connected to the shielding member 4 to control the rotation of the shielding member 4 to adjust the air outlet area of ​​the first air outlet 31 .

[0068] The fan hood 3 is used to raise the fan hood 3, and a first air outlet 31 is opened in the fan hood 3. The shielding member 4 is arranged relative to the first air outlet 31 to shield the first air outlet 31. The shielding member 4 is controlled by a controller to rotate along the rotating shaft 32 to change the shielding area of ​​the first air outlet 31 of the shielding member 4, thereby adjusting the air outlet area of ​​the first air outlet 31.

[0069] The shielding member 4 includes a plurality of shielding parts 41. The controller can control the plurality of shielding parts 41 to rotate simultaneously, and the shielding areas of the plurality of first air outlets 31 by the plurality of shielding parts 41 change simultaneously, and the air outlet areas of the plurality of first air outlets 31 are adjusted simultaneously. The controller can also control a preset number of shielding parts 41 to rotate, and adjust the air outlet areas of several first air outlets 31 among the plurality of first air outlets 31. The controller adjusts the air outlet area of ​​the first air outlet 31 by controlling the number of rotations and the rotation angle of the shielding part 41. The controller can adjust the number of rotations and the rotation angle of the shielding part 41 according to the actual needs of the user, so as to accurately adjust the air outlet area, and can meet the wide range of needs of more users.

[0070] Alternatively, if Figure 1 As shown, the refrigerator also includes a second chamber, which is connected to the first chamber through an air flow channel 5; wherein a second air outlet 34 is provided on the side wall of the fan cover 3, and the air flow generated by the fan 1 passes through the second air outlet 34 and the air flow channel 5 in sequence and flows into the second chamber.

[0071] The fan cover 3 is provided with a first air outlet 31 to supply air to the first chamber, so as to adjust the temperature of the first chamber. The second chamber is connected with the first chamber through the air flow channel 5. The fan cover 3 is facing the second chamber, and a second air outlet 34 is opened on the side wall. The airflow generated by the fan 1 passes through the second air outlet 34 and the air flow channel 5 in sequence. When the temperature of the second chamber needs to be adjusted, the second air outlet 34 of the fan cover 3 is opened, and the airflow generated by the fan 1 flows from the second air outlet 34 into the air flow channel 5 to blow toward the second chamber, so as to adjust the temperature of the second chamber. If only the temperature of the first chamber needs to be adjusted, the second air outlet 34 is closed, and only the shielding member 4 is controlled by the controller to open the first air outlet 31 to adjust the air outlet area of ​​the first air outlet 31; if only the temperature of the second chamber needs to be adjusted, the first air outlet 31 is closed and the second air outlet 34 is opened; if the temperatures of both the first chamber and the second chamber need to be adjusted, the first air outlet 31 and the second air outlet 34 are both opened; if the temperatures of both the first chamber and the second chamber have reached the set temperature, the first air outlet 31 and the second air outlet 34 are both closed.

[0072] like Figure 4 As shown, the refrigerator also includes a rear cover plate 6, which is provided with air holes 61. The fan 1 generates a large amount of heat when working for a long time. The setting of the air holes 61 allows the heat generated by the fan 1 to be diffused to avoid affecting the normal operation of the fan 1.
