[0050] Figure 1 This is a control logic diagram of a refrigerator control method according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 10 This invention provides a method for controlling a refrigerator. The refrigerator includes an air duct assembly, a passage opening and closing device, and storage compartments. The air duct assembly includes a first air duct body 1 and an air distribution plate 2. The first air duct body 1 is provided with a first air duct 10, and a first air outlet 14 and a second air outlet 15 communicating with the first air duct 10 are arranged side by side on the top wall of the first air duct body 1. An air inlet 17 communicating with the first air duct 10 is provided on the rear wall of the first air duct body 1. The first air outlet 14 communicates with a storage compartment, and the second air outlet 15 communicates with a storage compartment.

[0051] There are two air distribution plates 2, both located within the first air duct 10 and above the air inlet 17. Each air distribution plate 2 has a first edge and a second edge arranged opposite to each other, with the first edge of each plate horizontally positioned. One air distribution plate 2 is connected to the first edge of the other air distribution plate 2 around its first edge; and each air distribution plate 2 is rotatably arranged relative to the first air duct body 1 around its first edge. The first edge of each air distribution plate 2 is located below the junction between the first air outlet 14 and the second air outlet 15.

[0052] The air inlet 17 is equipped with a centrifugal impeller 3, which is located inside the first air duct 10 and below the two air distribution plates 2.

[0053] The channel opening and closing device is configured to open or close the first air outlet 14 and the second air outlet 15. Further, the refrigerator's air duct assembly also includes a second air duct body 5, within which a second air duct 51 and a third air duct 52 are disposed. The second air duct 51 connects to the first air outlet 14, and the third air duct 52 connects to the second air outlet 15. The channel opening and closing device includes a first damper 511 and a second damper 521. The first damper 511 is installed within the second air duct 51, and the second damper 521 is installed within the third air duct 52. In some alternative embodiments, the first damper 511 is installed at the first air outlet 14, and the second damper 521 is installed at the second air outlet 15. The angles of the first damper 511 and the second damper 521 are adjustable according to actual needs.

[0054] When the centrifugal impeller 3 is powered on, it rotates, driving cold air through the air inlet 17 into the first air duct 10 along the radial direction of the centrifugal impeller 3. The upward-flowing cold air flows into the first air outlet 14 and the second air outlet 15 respectively. As the cold air flows upward, the two air distribution plates 2 rotate. The two air distribution plates 2 and the inner walls of the first air duct 10 on both sides divide the cold air at the upper end of the first air duct 10 into two parts. One part is delivered to the first air outlet 14, and the other part is delivered to the second air outlet 15. The angle between the two air distribution plates 2 and the air inlet 17, the first air outlet 14 and the second air outlet 15 allows the ventilation volume of the two parts of cold air to be changed, thereby realizing the adjustment of the ventilation volume of the two parts of cold air according to actual needs.

[0055] Preferably, the refrigerator control method includes:

[0056] S1, obtain the working status and / or working level of the refrigerator's storage compartment corresponding to the first air outlet 14; and obtain the working status and / or working level of the refrigerator's storage compartment corresponding to the second air outlet 15.

[0057] S2, determine the preset position reached by each air distribution plate 2 and the corresponding opening degree of the first air outlet 14 and the second air outlet 15 according to the working status and / or working level.

[0058] S3, rotate the two air distribution plates 2 so that each air distribution plate 2 rotates to the corresponding preset position, and at the same time, the channel opening and closing device controls the first air outlet 14 and the second air outlet 15 to open their respective opening degrees.

[0059] In some alternative embodiments of the present invention, the refrigerator control method may include: S1, obtaining the air intake demand of the first air outlet 14 and the second air outlet 15; S2, determining the rotation angle of each air distribution plate 2 and the corresponding opening degree of the first air outlet 14 and the second air outlet 15 based on the air intake demand; S3, rotating the two air distribution plates 2 so that each air distribution plate 2 rotates to a preset position by a corresponding rotation angle, while simultaneously controlling the channel opening and closing device to open the first air outlet 14 and the second air outlet 15 to their respective opening degrees.

[0060] According to the cooling needs of each storage room, the rotating air distribution plate 2 distributes the cold air to the first air outlet 14 and the second air outlet 15. Combined with the opening of the first air outlet 14 and the second air outlet 15, the cooling needs of different storage rooms are met. Compared with continuously supplying air to the storage rooms, the cold air supply volume is adjustable, and the cold air is distributed on demand, saving resources.

[0061] In some embodiments of the present invention, the preset position reached by each air distribution plate 2 and the corresponding opening degree of the first air outlet 14 and the second air outlet 15 are determined according to the relationship table between the working state and / or working level and the preset position reached by each air distribution plate 2 and the opening degree of the first air outlet 14 and the second air outlet 15.

[0062] In some embodiments of the present invention, the storage compartment of the refrigerator corresponding to the first air outlet 14 is a refrigerator compartment 6, and the refrigerator compartment 6 operates in a cooling state and a non-cooling state. The storage compartment of the refrigerator corresponding to the second air outlet 15 is a variable temperature compartment 7, and the operating state and / or operating setting of the variable temperature compartment 7 is a non-cooling state, a cooling state, a variable temperature refrigerator state cooling setting, a variable temperature zero degree Celsius cooling setting, and a variable temperature freezer state cooling setting.

[0063] In some embodiments of the present invention, when the refrigerator compartment 6 is in a non-cooling state, the passage opening and closing device controls the first air outlet 14 to close; when the variable temperature compartment 7 is in a non-cooling state, the passage opening and closing device controls the second air outlet 15 to close.

[0064] In some embodiments of the present invention, such as Figure 4 As shown, when the refrigerator compartment 6 is in cooling mode: the passage opening and closing device controls the first air outlet 14 to be fully opened. The preset position corresponding to one air distribution plate 2 is such that the second edge of the air distribution plate 2 is above the first edge of the air distribution plate 2, and the edge of the first air outlet 14 adjacent to the second air outlet 15 is on the plane where the air distribution plate 2 is located. The angle between the air distribution plate 2 and the horizontal plane is the first angle. The preset position corresponding to the other air distribution plate 2 is such that the second edge of the air distribution plate 2 is below the first edge of the air distribution plate 2, and the second edge of the air distribution plate 2 is below the second air outlet 15. The angle between the air distribution plate 2 and the horizontal plane is the second angle, which is smaller than the first angle.

[0065] For example, when the refrigerator compartment 6 is in cooling mode, the first air outlet 14 is fully open, and the air distributor 2 rotates to the preset position. At this time, the air distributor 2 and the inner wall of the first air duct 1 divide the cold air supply into two parts. Due to the preset position of the air distributor 2, the cold air supply near the first air outlet 14 is greater than the cold air supply near the second air outlet 15. Meanwhile, the opening of the variable temperature compartment 7 can be adjusted according to its working state and / or working level to open the second air outlet 15 accordingly. For example, when the variable temperature compartment 7 is in non-cooling mode, the opening of the second air outlet 15 is zero, i.e., closed. When the variable temperature compartment 7 is in the variable temperature refrigeration mode, the opening of the second air outlet 15 is 30 degrees. When the variable temperature compartment 7 is in the variable temperature zero degree Celsius cooling mode, the opening of the second air outlet 15 is 60 degrees. When the variable temperature compartment 7 is in the variable temperature freezing mode, the opening of the second air outlet 15 is 90 degrees.

[0066] In some embodiments of the present invention, such as Figure 5 As shown, when the refrigerator compartment 6 is in a non-cooling state and the variable temperature compartment 7 is in a cooling state: the passage opening and closing device controls the first air outlet 14 to close; the passage opening and closing device controls the second air outlet 15 to open. The preset position corresponding to one air distribution plate 2 is that the second edge of the air distribution plate 2 is above the first edge of the air distribution plate 2, and the edge of the second air outlet 15 adjacent to the first air outlet 14 is on the plane where the air distribution plate 2 is located, and the angle between the air distribution plate 2 and the horizontal plane is the third angle; the preset position corresponding to the other air distribution plate 2 is that the second edge of the air distribution plate 2 is below the first edge of the air distribution plate 2, and the second edge of the air distribution plate 2 is below the first air outlet 14, and the angle between the air distribution plate 2 and the horizontal plane is the fourth angle, which is smaller than the third angle.

[0067] Furthermore, when the refrigerator compartment 6 is in a non-cooling state and the variable temperature compartment 7 is in a cooling state, the opening degree of the second air outlet 15 is determined according to the working state or operating level of the variable temperature compartment 7. For example: when the variable temperature compartment 7 is in a non-cooling state, the opening degree of the second air outlet 15 is zero, that is, closed; when the variable temperature compartment 7 is in the variable temperature refrigerator cooling level, the opening degree of the second air outlet 15 is 30 degrees; when the variable temperature compartment 7 is in the variable temperature zero degree Celsius cooling level, the opening degree of the second air outlet 15 is 60 degrees; when the variable temperature compartment 7 is in the variable temperature freezer cooling level, the opening degree of the second air outlet 15 is 90 degrees.

[0068] In some embodiments of the present invention, that is, when the variable temperature compartment 7 is in a cooling state and when the operating setting of the variable temperature compartment 7 is the variable temperature refrigeration state cooling setting, the channel opening and closing device controls the second air outlet 15 to open to a first preset opening degree. When the operating setting of the variable temperature compartment 7 is the variable temperature zero degree Celsius state cooling setting, the channel opening and closing device controls the second air outlet 15 to open to a second preset opening degree. When the operating setting of the variable temperature compartment 7 is the variable temperature freezing state cooling setting, the channel opening and closing device controls the second air outlet 15 to open to a third preset opening degree. The first preset opening degree is less than the second preset opening degree, the second preset opening degree is less than the third preset opening degree, and the third preset opening degree is when the second air outlet 15 is fully open. The first preset opening degree can be 30 degrees, the second preset opening degree can be 60 degrees, and the third preset opening degree can be 90 degrees.

[0069] In some embodiments of the present invention, a plurality of third air outlets 16 communicating with the first air duct 10 are provided on the front wall of the first air duct; at least two third air outlets 16 are provided at the upper end of the first air duct, and are located on both sides of the first air outlet 14 and the second air outlet 15, and the remaining third air outlets 16 are provided below the air inlet 17. The third air outlets 16 communicate with the freezer compartment 8, and the third air outlets 16 continuously supply air to the freezer compartment 8 to meet the cooling requirements of the freezer compartment 8. The air duct assembly is provided on the rear side of the freezer compartment 8.

[0070] In some embodiments of the present invention, reference is made to... Figures 2 to 10 One air distributor 2 is rotatably connected to the first edge of another air distributor 2 about its first edge, so that the two air distributors 2 are rotatably arranged relative to each other. The refrigerator also includes two drive motors 4. A rotating shaft 21 is fixed to the first edge of one air distributor, and a bushing 22 is fixed to the first edge of the other air distributor, with the rotating shaft 21 inserted into the bushing 22. The rotating shaft 21 is connected to one drive motor 4 via a gear assembly. The bushing 22 is connected to the other drive motor 4 via a gear assembly.

[0071] In some embodiments of the present invention, for ease of rotation, the length of each air distribution plate 2 from its second edge to its first edge is less than the distance between the first edge of the air distribution plate 2 and the top wall of the first air duct body 1; the length of each air distribution plate 2 from its second edge to its first edge is less than the distance between the first edge of the air distribution plate 2 and the air inlet 17.

[0072] In some embodiments of the present invention, one air distribution plate 2 is fixedly connected to the first edge of another air distribution plate 2 around its first edge, and the included angle between the two air distribution plates 2 is 100° to 160°, so that when the two air distribution plates 2 are rotated to a position where the second edges of the two air distribution plates 2 are both above the first edge, the inner walls of the two air distribution plates 2 and the first air duct 10 form two air ducts on both sides of the two air distribution plates 2 respectively supplying air to the first air outlet 14 and the second air outlet 15; when the two air distribution plates 2 are rotated to a position where one air distribution plate 2 is above the other air distribution plate 2, the inner walls of each air distribution plate 2 and the first air duct 10 form two air ducts on both sides of each air distribution plate 2 respectively supplying air to the first air outlet 14 and the second air outlet 15.

[0073] In some embodiments of the present invention, the first air duct body 1 includes an air duct cover plate 11, a mounting shell 12, and at least two guide ribs 13. The mounting shell 12 is fastened to the air duct cover plate 11, and an air inlet 17 is disposed on the rear wall of the mounting shell 12. At least two guide ribs 13 are disposed on the rear wall of the mounting shell 12 and protrude forward from the rear wall of the mounting shell 12. The at least two guide ribs 13, together with the air duct cover plate 11 and the rear wall of the mounting shell 12, define the first air duct 10. A first air outlet 14 and a second air outlet 15 are disposed on the top wall of the mounting shell 12, and a third air outlet 16 is disposed on the air duct cover plate 11.

[0074] Furthermore, at least two guide ribs 13 include two first ribs 131 and two second ribs 132. The two first ribs 131 extend downward from the upper end of the first air duct 10 to the lower end of the first air duct 10, and the distance between the two first ribs 131 remains constant from top to bottom, then gradually decreases, gradually increases, gradually decreases again, and then remains constant. The two second ribs 132 are disposed on the lower side of the air inlet 17, and the upper ends of the two second ribs 132 are connected to each other. The two second ribs 132 extend downward from top to bottom to the lower end of the first air duct 10, and the two second ribs 132 gradually move away from each other from top to bottom and then gradually move closer until they extend vertically, so as to divide the lower end of the first air duct 10 into two sub-air ducts, each sub-air duct being connected to at least one third air outlet 16.

[0075] The first air outlet 14 and the second air outlet 15 are located between the two first guide ribs 131, and part or all of the air inlet 17 is located on the upper side of the narrowest position between the two first guide ribs 131.

[0076] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
