The cabinet 10 comprises an evaporation chamber 101 and a storage space 102, and the evaporation chamber 101 is located at the bottom of the cabinet 10. The evaporation chamber 101 comprises a return air port 1011, and the evaporation chamber 101 and the storage space 102 are connected through the return air port 1011 of the evaporation chamber 101. The door body 20 is rotatably connected to the cabinet 10, and the door body 20 is used to open or close the storage space 102. The grille assembly 30 is rotatably arranged at the return air port 1011 of the evaporation chamber 101. The center of gravity of the grille assembly 30 is not located on the rotation axis of the grille assembly 30, so that the grille assembly 30 can be rotated to a preset position under the action of gravity. The suction assembly 40 comprises a first suction member 401 arranged on the grille assembly 30 and a second suction member 402 arranged in linkage with the door body 20. During the closing process of the door body 20, the first suction member 401 and the second suction member 402 are close to each other to attract each other, driving the grille assembly 30 to rotate to open the return air port 1011 of the evaporation chamber 101. During the opening process of the door body 20, the first suction member 401 and the second suction member 402 are separated, and the grille assembly 30 rotates to a preset position under the action of gravity to close the return air port 1011 of the evaporation chamber 101.

[0044] The refrigerator provided by the embodiment of the present disclosure is provided with a grille assembly 30 and a suction assembly 40 at the return air port 1011 of the evaporation chamber 101 located at the bottom of the box body 10, and the first suction member 401 is located on the grille assembly 30, and the second suction member 402 is arranged in linkage with the door body 20, and the center of gravity of the grille assembly 30 is not located on the rotation axis of the grille assembly 30, so that the first suction member 401 and the second suction member 402 are separated from each other during the opening of the door body 20, and the grille assembly 30 rotates to a preset position under the action of gravity to close the return air port 1011 of the evaporation chamber 101. In addition, when the door body 20 is opened, the humid air outside the box body 10 enters the evaporation chamber 101 through the return air port 1011 of the evaporation chamber 101, reduces the frosting speed and amount of the evaporator, prolongs the cycle of heating defrosting, and reduces energy consumption. Furthermore, when the door 20 is closed, the first suction member 401 and the second suction member 402 are brought close to attract each other, driving the grille assembly 30 to rotate to open the return air port 1011 of the evaporation chamber 101, so as to realize the normal refrigeration function of the refrigerator through the evaporator.

[0045] Optionally, the grille assembly 30 includes: a grille member 301. The grille member 301 is provided with ventilation holes 3011 and a wind shield 3012. The grille member 301 is rotatably provided at the return air outlet 1011 of the evaporation chamber 101, and the center of gravity of the grille member 301 is not located on the rotation axis. When the grille member 301 rotates to a preset position under the action of gravity, the wind shield 3012 can block the return air outlet 1011 of the evaporation chamber 101 to close the return air outlet 1011 of the evaporation chamber 101. The first suction member 401 is provided at the grille member 301. During the closing process of the door body 20, the first suction member 401 and the second suction member 402 are close to each other to attract each other, driving the grille member 301 to rotate, so that the ventilation holes 3011 connect the evaporation chamber 101 and the storage space 102 to open the return air outlet 1011 of the evaporation chamber 101. The number of grille members 301 is one or more. When there are multiple grille members 301, the multiple grille members 301 are vertically arranged at the return air outlet 1011 of the evaporation chamber 101, and when the grille members 301 rotate to a preset position under the action of gravity, the multiple wind shields 3012 of the multiple grille members 301 are docked to block the return air outlet 1011 of the evaporation chamber 101 to close the return air outlet 1011 of the evaporation chamber 101.

[0046] In this embodiment, by providing ventilation holes 3011 on the grille 301, the ventilation holes 3011 of the grille 301 are used to connect the evaporation chamber 101 and the storage space 102, so that the normal refrigeration function of the refrigerator is realized through the evaporator. In addition, by providing a wind shield 3012, when the grille 301 is rotated to a preset position, the wind shield 3012 can block the return air port 1011 of the evaporation chamber 101 to close the return air port 1011 of the evaporation chamber 101. In this way, when the door 20 is opened, the humid air outside the box 10 enters the evaporation chamber 101 through the return air port 1011 of the evaporation chamber 101, the frost speed and amount of the evaporator are reduced, the cycle of heating defrosting is extended, and the energy consumption is reduced. At the same time, when multiple grille members 301 are included, multiple wind shields 3012 of multiple grille plates are connected to block the return air outlet 1011 of the evaporation chamber 101, so that the return air outlet 1011 of the evaporation chamber 101 is blocked by multiple wind shields 3012 to close the return air outlet 1011 of the evaporation chamber 101.

[0047] Optionally, combined Figure 5 , Figure 6 and Figure 7 As shown, the grille member 301 includes: a plurality of grille plates and a connecting plate 3013. The plurality of grille plates are arranged at intervals to form ventilation holes 3011 between the plurality of grille plates. The connecting plate 3013 is connected to each grille plate. The grille plates located on the outside serve as wind shields 3012.

[0048] In this embodiment, multiple grille plates are provided to form ventilation holes 3011 between the multiple grille plates, so that the evaporation chamber 101 and the storage space 102 are connected by the ventilation holes 3011, so that the normal refrigeration function of the refrigerator is realized through the evaporator. In addition, by providing multiple grille plates, foreign matter entering the evaporation chamber 101 can be reduced, thereby improving the practicality of the refrigerator. At the same time, by providing a connecting plate 3013, the multiple grille plates are constructed as a whole, so that the multiple grille plates rotate at the same time, and then the return air port 1011 of the evaporation chamber 101 is opened or closed by the grille member 301. When the door body 20 is opened, the humid air outside the box body 10 enters the evaporation chamber 101 through the return air port 1011 of the evaporation chamber 101, thereby reducing the frosting speed and amount of the evaporator, extending the cycle of heating defrosting, and reducing energy consumption.

[0049] Optionally, combined Figure 6 and Figure 7As shown, the plurality of grid plates include: a first grid plate 3014, a second grid plate 3015, a third grid plate 3016 and a fourth grid plate 3017. The first grid plate 3014, the second grid plate 3015, the third grid plate 3016 and the fourth grid plate 3017 are all connected to the connecting plate 3013. When the return air outlet 1011 of the evaporation chamber 101 is closed, the fourth grid plate 3017 is shielded from the return air outlet 1011 of the evaporation chamber 101 as a wind shield 3012 to close the return air outlet 1011 of the evaporation chamber 101. The widths of the first grid plate 3014 and the third grid plate 3016 are equal, which is A. The widths of the second grid plate 3015 and the fourth grid plate 3017 are equal, which is B. Wherein, A is smaller than B.

[0050] In this embodiment, the widths of the first grid plate 3014, the second grid plate 3015, the third grid plate 3016 and the fourth grid plate 3017 are set so that the center of gravity of the grid member 301 is not located on the rotation axis of the grid member 301, so that the grid member 301 can rotate to a preset position under the action of gravity, thereby closing the return air port 1011 of the evaporation chamber 101. When the door body 20 is opened, the humid air outside the box body 10 enters the evaporation chamber 101 through the return air port 1011 of the evaporation chamber 101, reduces the frosting speed and amount of the evaporator, prolongs the cycle of heating defrosting, and reduces energy consumption.

[0051] Optionally, combined Figure 6 and Figure 7 As shown, the first grid plate 3014, the second grid plate 3015, the third grid plate 3016 and the fourth grid plate 3017 are arranged in sequence to form ventilation holes 3011. The first side end surfaces of the first grid plate 3014, the second grid plate 3015 and the third grid plate 3016 are flush, and the end surface of the fourth grid plate 3017 on the first side protrudes from the end surfaces of the first grid plate 3014, the second grid plate 3015 and the third grid plate 3016 on the side, so that the center of gravity of the grid member 301 is not located on the rotation axis. When there are multiple grid members 301, the fourth grid plates 3017 of adjacent grid members 301 are connected to block the return air port 1011 of the evaporation chamber 101 to close the return air port 1011 of the evaporation chamber 101.

[0052] In this embodiment, the positional relationship among the first grid plate 3014, the second grid plate 3015, the third grid plate 3016 and the fourth grid plate 3017 is set so that the center of gravity of the grid member 301 is not located on the rotation axis, and then when the door body 20 is opened, the grid member 301 can rotate to a preset position under the action of gravity to close the return air port 1011 of the evaporation chamber 101. When the door body 20 is opened, the humid air outside the cabinet 10 enters the evaporation chamber 101 through the return air port 1011 of the evaporation chamber 101, thereby reducing the frosting speed and amount of the evaporator, extending the cycle of heating defrosting, and reducing energy consumption.

[0053] Optionally, combined Figure 6 and Figure 7 As shown, the first grid plate 3014, the second grid plate 3015, the third grid plate 3016 and the fourth grid plate 3017 are parallel to each other. In this way, the ventilation speed of the ventilation hole 3011 can be increased when the return air port 1011 of the evaporation chamber 101 is opened, and the practicality of the grid member 301 is improved.

[0054] Optionally, combined Figures 4 to 7 As shown, the housing 10 further includes: a stopper 103. The stopper 103 is arranged on the cavity wall of the return air outlet 1011 of the evaporation chamber 101. The grille member 301 further includes: a limiting portion 3018. The limiting portion 3018 is arranged on one side of the connecting plate 3013. When the wind shield 3012 blocks the return air outlet 1011 of the evaporation chamber 101, the limiting portion 3018 abuts against the stopper 103 of the housing 10, so that the wind shield 3012 is vertically arranged on the return air outlet 1011 of the evaporation chamber 101. When there are multiple grille members 301, the limiting portion 3018 of the grille member 301 located on the upper side in the vertical direction abuts against the wind shield 3012 of the grille member 301 located on the lower side in the vertical direction adjacent thereto.

[0055] In this embodiment, the stopper 103 and the limiting portion 3018 are provided, so that the wind shield 3012 is vertically arranged at the return air outlet 1011 of the evaporation chamber 101 through the contact between the stopper 103 and the limiting portion 3018, so that the return air outlet 1011 of the evaporation chamber 101 is closed. At the same time, in the case of multiple grille members 301, the limiting portion 3018 of the grille member 301 on the upper side of the vertical direction contacts the wind shield 3012 of the grille member 301 on the lower side of the vertical direction, so that the limiting fixation between the two adjacent grille members 301 is achieved, and then the multiple wind shields 3012 are vertically arranged at the return air outlet 1011 of the evaporation chamber 101, so that the return air outlet 1011 of the evaporation chamber 101 is closed.

[0056] Optionally, the grille component 30 further includes: a first protrusion. The first protrusion is disposed at both ends of the grille member 301. The box body 10 further includes: a first groove. The first protrusion is rotatably disposed in the first groove.

[0058] Optionally, the grille assembly 30 further includes: a rotating shaft. The rotating shaft is disposed through the grille member 301, and two ends of the rotating shaft protrude from opposite end surfaces of the grille member 301 to form a second protrusion.

[0059] In this embodiment, the second protrusion is rotatably disposed in the second groove to realize the rotational connection between the grille assembly 30 and the housing 10 , thereby realizing the opening and closing of the return air port 1011 of the evaporation chamber 101 .

[0060] Specifically, combined Figure 6 As shown, the protrusion 302 shown in the figure can be either the first protrusion or the second protrusion.

[0061] For example, in combination Figure 6 As shown, the rotation axis C of the grille member is located on the protrusion 302, and the center of gravity of the grille member 301 is D. Thus, by setting the center of gravity of the grille member 301 to the left of the rotation axis, when the door body 20 is opened, the grille member 301 rotates to a preset position under the action of gravity.

[0062] Optionally, the first attraction member 401 includes: a first magnet member. The first magnet member is arranged on one side of the grille member 301. The second attraction member 402 includes: a second magnet member. The second magnet member is arranged in conjunction with the door body 20 and is opposite to the first magnet member. The magnetism of the second magnet member is different from that of the first magnet member.

[0063] In this embodiment, a first magnet member and a second magnet member are provided, and the magnetism of the second magnet member is different from that of the first magnet member, so that when the door body 20 is closed, the first magnet member and the second magnet member are attracted to each other, driving the grille member 301 to rotate, thereby opening the return air outlet 1011 of the evaporation chamber 101.

[0064] Optionally, combined Figure 4 As shown, the second suction member 402 is disposed on the door body 20 .

[0065] In this embodiment, the second suction member 402 is disposed on the door body 20 so that when the second suction member 402 and the first suction member 401 are close to each other, suction can be generated, thereby driving the grille member 301 to rotate, thereby opening the return air port 1011 of the evaporation chamber 101.

[0066] Optionally, the refrigerator further comprises: a connecting piece. The second suction piece 402 is connected to the door body 20 via the connecting piece.

[0067] In this embodiment, a connecting member is provided to realize the linkage setting of the second suction member 402 and the door body 20. Moreover, by providing the connecting member, when the distance between the first suction member 401 and the door body 20 is far, the distance between the first suction member 401 and the second suction member 402 can be reduced by the connecting member, so that when the door body 20 is closed, the first magnet member and the second magnet member attract each other, driving the grille member 301 to rotate, thereby realizing the opening of the return air port 1011 of the evaporation chamber 101.

[0068] It is understandable that the connecting member can be a connecting rod or a wire connection, as long as the connecting member can make the second suction member 402 and the door body 20 work together, that is, the second suction member 402 can move with the rotation of the door body 20. The disclosed embodiment does not limit this.
