Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of refrigeration equipment, and in particular to a refrigerator. BACKGROUND

[0002] In some refrigerators, an ice maker is mounted, and the ice maker is used to quickly generate ice cubes to meet the ice demand of users.

[0003] In the related art, the ice maker arranged on the door body needs to be supplied with cold energy from the cabinet. One way is to use an air duct to guide cold air from the cabinet into the ice maker to reduce the temperature in the ice maker, and freeze the water in the ice tray to form ice cubes to realize the ice making function.

[0004] However, the ice making efficiency of the ice maker in the related art is low. Utility model content

[0005] Embodiments of the present application provide a refrigerator with an ice maker, which can improve the ice making efficiency.

[0006] In a first aspect, embodiments of the present application provide a refrigerator, which includes:

[0007] a cabinet configured to form a refrigeration compartment;

[0008] a door body rotatably connected to the cabinet and used to open or close the refrigeration compartment;

[0009] a refrigeration system arranged in the cabinet and used to reduce the air temperature of the refrigeration compartment;

[0010] an ice maker mounted on the door body or the cabinet and used to make ice cubes; the ice maker includes:

[0011] an ice tray configured to form ice cells for forming ice cubes;

[0012] an air guide shell arranged above the ice tray and surrounding the ice tray to form a relatively sealed air guide cavity;

[0013] an air supply air duct located above the side of the ice tray, the air supply air duct being used to send cold air blown from an evaporator of the refrigeration system into the air guide shell;

[0014] a wind guide gap is provided around the ice tray to allow cold air in the air guide cavity to be discharged downward to a cavity below the ice tray;

[0015] the air guide cavity covers all ice cells of the ice tray;

[0016] the air pressure in the air guide cavity is higher than the air pressure in the cavity below the ice tray.

[0017] The ice maker of the embodiment of the present application forms ice grids for ice making by setting ice making trays, and sends the cold air blown by the evaporator into the air guide shell by setting the air supply air duct; the air guide shell is set above the ice making tray, and forms a relatively sealed air guide cavity together with the ice making tray, the air guide cavity covers all the ice grids of the ice making tray, and the air guide cavity plays a role of buffering, mixing and diffusing the cold air sent into the air guide cavity by the air supply air duct, thereby improving the uniformity of the distribution of the cold air on all the ice grids and the consistency of the freezing rate of all the ice grids, and thereby improving the ice making efficiency. The air guide gap is arranged at the periphery of the ice making tray, so that the cold air in the air guide cavity is discharged downward to the cavity below the ice making tray, so that the cold air with large capacity in the air guide cavity enters the cavity below the ice making tray through the air guide gap, the air guide gap guides and limits the cold air, so that the distribution of the cold air on all the ice grids of the ice making tray is more uniform; and the air pressure in the air guide cavity is higher than the air pressure in the cavity below the ice making tray, a pressure difference is formed between the air guide cavity above the ice making tray and the cavity below the ice making tray, which can promote the flow of the cold air from above the ice making tray to below the ice making tray, thereby facilitating the flow of the cold air through the air outlet gap to all the ice grids on the entire surface of the ice making tray, and improving the uniformity of the distribution of the cold air on all the ice grids of the ice making tray.

[0018] In some embodiments of the present application, the air guide shell comprises a first plate portion and a second plate portion which are arranged opposite and spaced apart in a first direction; the first plate portion is provided with a first opening;

[0019] The ice making tray is mounted between the first plate portion and the second plate portion;

[0020] The air supply air duct is located on the side of the first plate portion away from the second plate portion and is fixedly connected with the first plate portion; the air supply air duct communicates with the air guide cavity through the first opening.

[0021] The air guide shell of the embodiment of the present application is provided with the first plate portion and the second plate portion, so that the ice making tray is mounted between the first plate portion and the second plate portion; the first opening is arranged on the first plate portion, so that the air supply air duct communicates with the air guide cavity through the first opening; the air supply air duct is located on the side of the first plate portion away from the second plate portion, so that the air supply air duct is located outside the air guide cavity, so that the cold air in the air supply air duct enters from the side of the air guide cavity, avoiding the air supply air duct extending into the air guide cavity to affect the uniformity of the distribution of the cold air in the air guide cavity.

[0022] In some embodiments of the present application, a first air guide gap is formed between the ice making tray and the second plate portion;

[0023] The air guide gap comprises the first air guide gap.

[0024] The first air guide gap is formed between the ice making tray and the second plate part, is located on the side of the ice making tray away from the air supply air duct, helps to guide the cold air to flow through and cover all ice cells of the ice making tray, and improves the uniformity of the distribution of the cold air on all ice cells.

[0025] In some embodiments of the present application, the ice maker further comprises a driving component configured to drive the ice making tray to rotate.

[0026] The driving component is fixed to the side of the first plate part facing the second plate part, and the driving component and the first plate part are relatively sealed. The driving component and the ice making tray form a second air guide gap. Alternatively, the driving component is fixed to the side of the first plate part away from the second plate part, and the first plate part and the ice making tray form the second air guide gap.

[0027] The air guide gap comprises the second air guide gap.

[0028] In the embodiments of the present application, the driving component is arranged in the air guide cavity, so that the structure of the ice maker is compact, the appearance is regular, and the assembly is facilitated. Moreover, the arrangement of the driving component makes the port of the air supply air duct and the ice making tray have a spacing, so that the cold air sent by the air supply air duct can first diffuse and distribute in the air guide cavity above the driving component, and the uniformity of the distribution of the cold air in the ice making tray is improved.

[0029] In the embodiments of the present application, the driving component is arranged outside the air guide cavity, so that the space in the air guide cavity is regular, the cold air flows smoothly, and the uniform distribution of the cold air is facilitated. Moreover, the arrangement of the driving component outside the air guide cavity can reduce the end turbulence caused by the arrangement of the driving component in the air guide cavity, and can avoid the influence of the cold air on the driving component, thereby prolonging the service life of the driving component.

[0030] In some embodiments of the present application, the interval size of the first air guide gap along the first direction is greater than the interval size of the second air guide gap along the first direction.

[0031] Thus, when the lengths of the first and second air guide gaps are the same, the air outlet area of ​​the first air guide gap is larger, while the air outlet area of ​​the second air guide gap is smaller. A larger gap size in the first air guide gap means that it has lower airflow resistance, reducing the resistance to cold air passing through it. This allows more cold air within the air guide cavity to flow towards the first air guide gap, contributing to a more uniform cooling effect across the entire ice-making tray surface and preventing excessive concentration of cold air near the air supply duct.

[0032] In some embodiments of this application, the air guide shell further includes:

[0033] The third plate portion and the fourth plate portion are arranged opposite to each other and spaced apart along the second direction, and the two ends of the third plate portion and the fourth plate portion are respectively connected to the first plate portion and the second plate portion along the first direction.

[0034] The top plate is fixed to the top of the first plate, the second plate, the third plate, and the fourth plate; the top plate and the ice-making tray are spaced apart along the depth direction of the ice-making tray, and the top plate, the first plate, the second plate, the third plate, the fourth plate, and the ice-making tray together form a relatively sealed air guide cavity;

[0035] Wherein, the second direction is perpendicular to the first direction, and the plane determined by the second direction and the first direction is perpendicular to the depth direction of the ice-making tray.

[0036] In some embodiments of this application, the air guide shell is provided with a third plate, a fourth plate, and a top plate, which together with the first plate and the second plate form a downward-opening chamber. The top plate is opposite to and spaced from the ice tray along the depth direction of the ice tray. In this way, the air guide shell and the ice tray form a relatively sealed air guide cavity. The air guide cavity diffuses and distributes the cold air sent in by the air supply duct, improving the uniformity of the cold air distribution on all ice grids on the ice tray.

[0037] In some embodiments of this application, a third air guide gap is formed between the ice-making tray and the third plate portion, and between the ice-making tray and the fourth plate portion, respectively;

[0038] The air guide gap includes the third air guide gap.

[0039] The two third air guiding gaps are arranged to form a ring-shaped air outlet gap together with the first air guiding gap and the second air guiding gap, so that cold air can be guided out from the edges of the ice making tray, the edge effect can be eliminated, and the ice cells at the edges of the ice making tray can be cooled as uniformly as the ice cells in the middle. Moreover, the ring-shaped air outlet gap enables the cold air in the air guiding cavity to flow out in various directions from the ice making tray, so that cold air can flow through all the ice cells on the ice making tray, thereby improving the uniformity of the distribution of the cold air and the ice making efficiency and consistency.

[0040] In some embodiments of the present application, along the first direction and from the first plate portion to the second plate portion, the spacing of the third air guiding gap along the second direction gradually increases.

[0041] In this way, along the direction away from the air supply air duct, the spacing of the third air guiding gap gradually increases, so that the resistance of the third air guiding gap gradually decreases and the amount of cold air flowing out gradually increases, that is, the farther away from the air supply air duct, the more cold air flows out from the third air guiding gap, the flow path of the cold air in the air guiding cavity can be increased, so that the cold air is more dispersed in the air guiding cavity, thereby improving the uniformity of the distribution of the cold air on all the ice cells on the ice making tray.

[0042] In some embodiments of the present application, the air supply air duct has a first air inlet, the first air inlet faces the air guiding cavity, and the first air inlet is located on one side of the air guiding cavity along the first direction.

[0043] The ice making tray has a center line along the first direction.

[0044] The first air inlet is symmetrically arranged about the center line.

[0045] In the embodiments of the present application, the first air inlet is symmetrically arranged about the center line of the ice making tray, so that the cold air blown out by the first air inlet along the second direction is symmetric about the center line, thereby improving the uniformity of the distribution of the cold air on the ice tray along the second direction.

[0046] In some embodiments of the present application, the first air inlet has a first size along the second direction.

[0047] The ice making tray has a second size along the second direction.

[0048] The ratio of the first size to the second size is greater than 4 / 5, and the first size is smaller than the size of the air guiding cavity along the second direction.

[0049] The second direction is perpendicular to the first direction, and the plane determined by the second direction and the first direction is perpendicular to the depth direction of the ice making tray.

[0050] In the embodiments of the present application, the ratio of the first size to the second size is greater than 4 / 5, so that the size of the first air inlet along the second direction is greater than 80% of the size of the ice-making tray along the second direction. In this way, the first air inlet can cover most of the ice-making tray along the second direction, which is beneficial to improve the uniformity of cold air distribution in the air guide cavity, improve the air supply volume, and further form a higher air pressure in the air guide cavity compared to the chamber below the ice-making tray, which is beneficial to improve the cold air flow rate and further improve the ice-making efficiency. The first size is smaller than the size of the air guide cavity along the second direction, that is, the first air inlet is located in the air guide cavity, avoiding the first air inlet extending out of the air guide cavity.

[0051] In some embodiments of the present application, the air supply air duct further has a second air inlet configured to communicate with a chamber where an evaporator of the refrigeration system is located.

[0052] Part of the second air inlet and part of the first air inlet are opposite and have a spacing along the first direction.

[0053] In this way, the second air inlet can match the second opening provided on the first side wall of the door liner, and the second air inlet can be located above the ice-making tray, facilitating the downward flow of cold air to cover the ice-making tray. Part of the second air inlet and part of the first air inlet are opposite and have a spacing along the first direction, which is beneficial to make the cold air of the second air inlet directly enter the first air inlet through the air supply air duct, reduce the flow resistance of the air supply air duct to the cold air, and improve the smoothness of the cold air entering the air guide cavity.

[0054] In some embodiments of the present application, the door liner of the door body is recessed away from the refrigeration compartment to form a recessed mounting portion.

[0055] The ice maker is mounted in the recessed mounting portion; the ice maker comprises:

[0056] An ice tray shell is open on both sides along the depth direction of the ice-making tray; the ice tray shell is fixed to the recessed mounting portion and has a spacing with the top end of the recessed mounting portion;

[0057] The ice-making tray is rotatably mounted in the ice tray shell;

[0058] A wind-blocking piece is located on the side of the ice-making tray facing the refrigeration compartment, and the wind-blocking piece is fixedly connected with the ice tray shell and the recessed mounting portion, respectively. The ice tray shell, the wind-blocking piece, and the recessed mounting portion jointly enclose the air guide cavity.

[0059] The air guide shell piece comprises part of the ice tray shell, the wind-blocking piece, and the recessed mounting portion.

[0060] In this embodiment, the air guide housing, by incorporating an ice tray shell, allows the ice tray to be installed within the shell, facilitating the overall assembly of the ice tray shell and ice tray into the recessed mounting portion. A gap exists between the top of the ice tray shell and the recessed mounting portion, providing space for the electrical connection terminals of the ice maker and the water inlet mechanism of the ice tray. This also allows the cold air supplied by the air duct to diffuse and distribute in the space above the ice tray shell before flowing onto the surface of the ice tray, improving the uniformity of cold air distribution across all ice grids. Furthermore, the air guide housing in this embodiment, by incorporating a baffle, seals the side of the air guide cavity facing the refrigeration chamber, and facilitates the removal of the baffle for maintenance of the ice tray, drive components, etc. Attached Figure Description

[0089] In order to make the objects, the embodiments and the advantages of the present application clearer, the following will be clear, complete description of the exemplary embodiments of the present application in conjunction with the accompanying drawings of the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0090] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0091] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to those components clearly listed, but can include other components not clearly listed or inherent to these products or devices.

[0092] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0093] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0094] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0095] In the related art, the ice maker arranged on the door body needs to export cold quantity from the cabinet to the ice maker. One way is to arrange an evaporator, which is connected to the refrigeration system on the side of the cabinet, and uses the evaporation of refrigerant to absorb heat to reduce the freezing of water in the ice tray to form ice blocks. Another way is to use an air duct to guide cold air from the cabinet into the ice maker to reduce the temperature in the ice maker, freeze the water in the ice tray to form ice blocks, and realize the ice making function.

[0096] Among them, the air supply air duct is arranged on the ice maker, and the cold air is introduced into the upper part of the ice tray through the air supply air duct, and then the cold air is exported from the ice tray through the return air duct, and the water in the ice tray is frozen to form ice blocks.

[0097] In the related art, since the cold air blown by the air supply air duct to the upper part of the ice tray is not uniformly distributed, the freezing speed of the ice blocks in the ice tray is inconsistent, which affects the ice making efficiency.

[0098] The present application research and development personnel found that there is no guiding structure between the cold air from the air supply air duct to the return air duct, resulting in more cold air on the side of the air supply air duct opposite to the air outlet.

[0099] Therefore, the present application research and development personnel designed an ice maker, which forms an air guiding cavity above the ice tray, and the air guiding cavity is in communication with the air supply air duct; and an air guiding gap is formed around the ice tray, so that the cold air in the air guiding cavity can enter the return air duct through the air guiding gap. In this way, the cold air entering the air supply air duct is buffered and dispersed in the air guiding cavity, improving the uniformity of the cold air distribution above the ice tray, and further improving the ice making efficiency.

[0100] Moreover, the air supply air duct is located on the side of the ice tray, and the cold air flows through the surface of the ice tray from the air supply air duct to the air guiding gap, which can further improve the uniformity of the cold air distribution above the ice blocks.

[0101] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0102] Reference Figure 1 The refrigerator provided by the embodiments of the present application includes a cabinet 100, which can be configured to form a refrigeration compartment 101 for storing articles.

[0103] The refrigeration compartment 101 can be provided in plurality to expand the storage space. According to different storage temperatures of the refrigeration compartment 101, the refrigeration compartment 101 can include at least one refrigeration compartment and at least one freezing compartment. The internal temperature of the refrigeration compartment can be maintained at about 0℃ to 5℃ to store articles in a refrigeration mode; the internal temperature of the freezing compartment can be maintained at about -30℃ to 0℃ to store articles in a freezing mode.

[0104] In some possible implementations, at least one refrigeration compartment 101 can also be provided as a vacuum chamber or a temperature-variable chamber, and the like, which will not be described herein again.

[0105] Exemplarily, the refrigeration compartment 101 can be provided in two, and the two refrigeration compartments 101 can be provided in a vertical direction in a stacked manner; or the two refrigeration compartments 101 can be provided in a horizontal direction in a side-by-side manner. One of the two refrigeration compartments 101 can be provided as a refrigeration compartment, and the other one can be provided as a freezing compartment.

[0106] In some embodiments, the cabinet 100 can include a cabinet inner container and a cabinet shell. The cabinet inner container can be configured with the refrigeration compartment 101. The cabinet shell can be connected to the outside of the cabinet inner container to form the appearance of the refrigerator.

[0107] The cabinet 100 can further include a cabinet insulation layer, which can be provided between the cabinet inner container and the cabinet shell. The cabinet insulation layer can thermally insulate the refrigeration compartment 101 to minimize the heat exchange between the refrigeration compartment 101 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0108] The refrigerator provided by the embodiments of the present application can further include a refrigeration system for providing cold energy to the refrigeration compartment 101. Exemplarily, the refrigeration system can be provided in the cabinet 100. The refrigeration system can include a compressor, a condenser, a throttling device and an evaporator connected in a circulation manner.

[0109] When the refrigeration system is running, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor, and delivers the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid, and delivers the refrigerant liquid to the throttling device. The throttling device depressurizes the refrigerant liquid to change the high-pressure and low-temperature refrigerant liquid into low-pressure and low-temperature refrigerant liquid, and delivers the refrigerant liquid to the evaporator. The evaporator receives the low-pressure and low-temperature refrigerant liquid, and boils the refrigerant liquid under isobaric conditions to absorb heat and vaporize to form refrigerant vapor, so as to reduce the temperature in the refrigeration compartment 101.

[0110] In the embodiments of the present application, the evaporating chamber is formed in the cabinet 100 to install the evaporator. The refrigeration compartment 101 communicates with the evaporating chamber under the action of the fan, so that the air flows between the refrigeration compartment 101 and the evaporating chamber to reduce the temperature of the refrigeration compartment 101.

[0111] Continuing to refer to Figure 1 , the refrigerator of the embodiments of the present application can further include a door body 200 rotatably connected to the cabinet 100 to open or close the refrigeration compartment 101.

[0112] Each refrigeration compartment 101 can correspondingly be provided with one door body 200; or each refrigeration compartment 101 can correspondingly be provided with two door bodies 200, and the two door bodies 200 can rotate in opposite directions to open or close the refrigeration compartment 101.

[0113] In some embodiments, as shown in Figure 1 and Figure 2 , the door body 200 can include a door inner liner 210. The door inner liner 210 faces the refrigeration compartment when the door body 200 closes the refrigeration compartment.

[0114] The door body 200 can include a door outer shell 220, which can be connected to the outside of the door inner liner 210 to form the appearance of the door body 200. The door outer shell 220 can be rotatably connected to the cabinet 100 to open or close the refrigeration compartment.

[0115] The door body 200 can further include a door thermal insulation member, which can be arranged in the gap between the door inner liner 210 and the door outer shell 220. The door thermal insulation member can thermally insulate the storage compartment to minimize heat exchange between the storage compartment and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator. The door thermal insulation member can be a foaming layer.

[0116] The refrigerator of the embodiments of the present application can further include an ice maker 300 for making ice cubes. The ice maker 300 can be installed on the cabinet 100 or the door body 200.

[0117] For example, as shown in Figure 1 andFigure 2 As shown, the ice maker 300 can be installed on the door body 200 to minimize the space occupied by the ice maker 300 in the refrigeration compartment 101 for storing articles, thereby facilitating the increase of the article capacity of the refrigerator.

[0118] For another example, the ice maker 300 can be installed on the cabinet 100, so that the entering and returning paths of the cold air can be shortened.

[0119] Referring to Figures 3 to 5 In some embodiments of the present application, the ice maker 300 can include an ice tray 310. The ice tray 310 is configured to form ice cells for forming ice cubes. Water is filled in the ice cells, and when the ice tray 310 is provided with cold energy by the refrigeration system, the water in the ice cells is frozen to form ice cubes.

[0120] In some embodiments, the ice maker 300 can further include a supply air duct 320 for supplying the cold air blown from the evaporator of the refrigeration system into the air guide shell 340.

[0121] In some embodiments, the refrigerator can further include a first air duct member configured to form a first air duct communicating the air guide cavity 301 and the evaporating chamber. Under the action of the fan, the cold air in the evaporating chamber enters the supply air duct 320 through the first air duct, and then enters the air guide shell 340 to reduce the temperature of the ice tray 310, so that the water in the ice cells is frozen to form ice cubes.

[0122] In some embodiments, the supply air duct 320 is located above the side of the ice tray 310, so that the supply air duct 320 can avoid directly facing some ice cells to cause uneven distribution of the cold air on the ice tray 310; and the supply air duct 320 located above the ice tray 310 can make the cold air flow downward to cover the ice tray 310.

[0123] Referring to Figure 4 and Figure 5 In some embodiments of the present application, the ice maker 300 can further include an air guide shell 340 covering above the ice tray 310 and forming a relatively sealed air guide cavity 301 with the ice tray 310.

[0124] The air guide gap is provided at the periphery of the ice tray 310 to allow the cold air in the air guide cavity 301 to flow downward to the chamber below the ice tray 310.

[0125] In this way, the cold air in the supply air duct 320 can enter the air guide cavity 301 and contact the ice tray 310 to freeze the water in the ice tray 310 to form ice cubes. Then, the cold air in the air guide cavity 301 is discharged downward to the chamber below the ice tray 310 through the air guide gap 302.

[0126] The air guide gap 302 can limit and guide the flow of cold air out of the air guide cavity 301, and can promote the uniformity of the distribution of cold air over all ice bins. Moreover, the cold air entering the air guide gap 302 from the air guide cavity 301 of large capacity can cause turbulence, which can help the mixing and uniformity of the cold air.

[0127] The air guide gap 302 can be formed at the edge of the ice making tray 310, which facilitates the arrangement and processing of the air guide gap 302.

[0128] The air guide gap 302 can be formed by the ice making tray 310 and the air guide shell 340, so that the influence of the cavity wall of the air guide cavity 301 on the movement of the ice making tray 310 can be avoided.

[0129] The air guide cavity 301 is relatively sealed. It can be understood that the cold air enters the air guide cavity 301 through the air supply duct 320 and flows out of the air guide cavity 301 through the air guide gap 302. Limited cold air leakage can exist at other positions of the air guide cavity 301 due to connections, structures, etc., which do not affect the cold air entering the air guide cavity 301 through the air supply duct 320 and flowing out of the air guide cavity 301 through the air guide gap 302. Moreover, the air guide cavity 301 is in communication with the chamber below the ice making tray 310 through the air guide gap 302, and the air guide cavity 301 is not in communication with the chamber below the ice making tray 310 through other positions.

[0130] In some embodiments of the present application, the chamber below the ice making tray 310 can be enclosed by other shells of the ice maker 300. The cavity wall of the chamber below the ice making tray 310 can be connected with the return air duct 330, which is configured to form a return air duct configured to blow the cold air in the chamber below the ice making tray 310 back to the evaporator.

[0131] The chamber below the ice making tray 310 can be provided with a crushed ice mechanism, an ice storage bucket, etc., wherein the crushed ice mechanism is used to crush the ice in the ice making tray 310 to form ice blocks; and the ice storage bucket is used to store the ice blocks.

[0132] In the embodiments of the present application, the air guide shell 340 covers all the ice bins of the ice making tray 310, so that the air guide cavity 301 covers all the ice bins of the ice making tray 310. In this way, the cold air in the air guide cavity 301 can cover all the ice bins, improve the uniformity of the cooling of all the ice bins, and thus improve the ice making efficiency.

[0133] The air guide cavity 301 covers all the ice bins of the ice making tray 310, which can be understood as that all the ice bins of the ice making tray 310 are located in the air guide cavity 301.

[0134] The air pressure in the air guide cavity 301 is higher than the air pressure in the cavity below the ice making tray 310, so that a pressure difference is formed between the air guide cavity 301 above the ice making tray 310 and the cavity below the ice making tray 310, which can promote the cold air to flow from above the ice making tray 310 to below the ice making tray 310, so as to facilitate the cold air to flow through the air outlet gap and pass through all the ice cells on the entire surface of the ice making tray 310, improve the uniformity of the cold air distribution on all the ice cells on the ice making tray 310. Moreover, the air flow driven by the pressure difference can help to reduce the temperature gradient between the surface of the ice making tray 310 and below the ice making tray 310, so that the entire surface of the ice making tray 310 can reach the required low temperature more uniformly, which helps to improve the ice making quality and consistency.

[0135] In combination Figure 4 and Figure 5 , Figure 4 and Figure 5 The dotted line with arrows in the above figures schematically shows the flow direction of the gas. Through the above arrangement, since the air supply air duct 320 is located above the ice making tray 310, the cold air sent by the air supply air duct 320 into the air guide cavity 301 blows towards the air guide cavity 301 above the ice making tray 310; the cold air flows downward and covers all the ice cells of the ice making tray 310 under the action of gravity and natural diffusion; in addition, the guiding action of the air outlet gap 302 causes the cold air to be guided to the edge of the ice making tray 310 after reaching the surface of the ice making tray 310, which further balances the distribution of the cold air on all the ice cells of the ice making tray 310.

[0136] Through the above arrangement, the ice maker 300 of the embodiment of the application forms ice grids for ice making by arranging the ice making tray 310, and sends the cold air blown by the evaporator into the air guide shell 340 by arranging the air supply air duct 320; the air guide shell 340 is arranged above the ice making tray 310, and forms a relatively sealed air guide cavity 301 together with the ice making tray 310, the air guide cavity 301 covers all the ice grids of the ice making tray 310, and the air guide cavity 301 plays a role of buffering, mixing and diffusing the cold air sent by the air supply air duct 320, thereby improving the uniformity of the distribution of the cold air on all the ice grids and the consistency of the freezing rate of all the ice grids, and thereby improving the ice making efficiency. The air guide gap 302 is arranged at the periphery of the ice making tray 310, so that the cold air in the air guide cavity 301 is discharged downward to the cavity below the ice making tray 310, so that the cold air with a large capacity in the air guide cavity 301 enters the cavity below the ice making tray 310 through the air guide gap 302, the air guide gap 302 guides and limits the cold air, so that the distribution of the cold air on all the ice grids of the ice making tray 310 is more uniform; and the air pressure in the air guide cavity 301 above the ice making tray 310 is higher than the air pressure in the cavity below the ice making tray 310, a pressure difference is formed between the air guide cavity 301 above the ice making tray 310 and the cavity below the ice making tray 310, which can promote the flow of the cold air from above the ice making tray 310 to below the ice making tray 310, thereby facilitating the flow of the cold air through the air outlet gap to all the ice grids on the entire surface of the ice making tray 310, and improving the uniformity of the distribution of the cold air on all the ice grids of the ice making tray 310.

[0137] In some embodiments of the application, in combination with Figure 6 , the air guide shell 340 comprises a first plate part 341 and a second plate part 342, and the first plate part 341 and the second plate part 342 are arranged opposite and spaced apart along a first direction.

[0138] The first direction can correspond to the X-axis direction in Figure 6 , and the first direction can be parallel to the length direction of the ice making tray 310.

[0139] The ice making tray 310 is installed between the first plate part 341 and the second plate part 342. For example, the ice making tray 310 is rotatably installed between the first plate part 341 and the second plate part 342, which facilitates the overturning and ice removal of the ice making tray 310.

[0140] In some embodiments of the application, a first opening is arranged on the first plate part 341 to communicate the air supply air duct 320 with the air guide cavity 301.

[0141] The air supply air duct 320 is located on the side of the first plate portion 341 away from the second plate portion 342 and is fixedly connected with the first plate portion 341. For example, the air supply air duct 320 can be clamped with the first plate portion 341, so that the air supply air duct 320 is simply assembled with the first plate portion 341. The port of the air supply air duct 320 is opposite to the first opening, so that the air supply air duct 320 is communicated with the air guide cavity 301 through the first opening. In this way, the air supply air duct 320 can send cold air into the air guide cavity 301.

[0142] In some embodiments, the end of the air supply air duct 320 extends into the first opening and is flush with the inner side of the first plate portion 341 facing the second plate portion 342. This can improve the air tightness of the connection between the air supply air duct 320 and the first plate portion 341, reduce the possibility of air leakage at the air supply air duct 320 and the first opening, and avoid the air supply air duct 320 extending into the air guide cavity 301 to affect the uniformity of the distribution of cold air in the air guide cavity 301.

[0143] Therefore, in the air guide shell 340 of the embodiments of the present application, the first plate portion 341 and the second plate portion 342 are provided, so that the ice making tray 310 is installed between the first plate portion 341 and the second plate portion 342. The first opening is provided on the first plate portion 341, so that the air supply air duct 320 is communicated with the air guide cavity 301 through the first opening. The air supply air duct 320 is located on the side of the first plate portion 341 away from the second plate portion 342, so that the air supply air duct 320 is located on the outside of the air guide cavity 301. The cold air in the air supply air duct 320 enters from the side of the air guide cavity 301, so as to avoid the air supply air duct 320 extending into the air guide cavity 301 to affect the uniformity of the distribution of cold air in the air guide cavity 301.

[0144] In some embodiments of the present application, the first air guide gap 3021 is formed between the ice making tray 310 and the second plate portion 342. The air guide gap 302 includes the first air guide gap 3021.

[0145] The first air guide gap 3021 can extend along the second direction, and the second direction can be perpendicular to the first direction. The second direction can correspond to Figure 6 the Y-axis direction in the middle.

[0146] In some embodiments, the two ends of the first air guide gap 3021 along the second direction protrude from the two ends of the ice making tray 310 along the second direction. In this way, the length of the first air guide gap 3021 along the second direction exceeds the length of the ice making tray 310 along the second direction. This can not only increase the air outlet area to increase the flow rate of cold air, but also make the cold air on the ice making tray 310 flow out through the first air guide gap 3021, so as to ensure the flowability of the cold air on the ice making tray 310 to ensure that the cold air can flow through the surfaces of all ice cells, thereby improving the uniformity of refrigeration.

[0147] The first air guide gap 3021 is formed between the ice making tray 310 and the second plate portion 342, is located on the side of the ice making tray 310 away from the air supply air duct 320, and helps to guide the cold air to flow through and cover all ice cells of the ice making tray 310, thereby improving the uniformity of the distribution of the cold air on all ice cells. By forming the first air guide gap 3021, the flow path of the cold air can be better controlled, so that the cold air sent by the air supply air duct 320 can enter the chamber below the ice making tray 310 from the first air guide gap 3021 across the ice making tray 310, thereby facilitating the increase of the flow path of the cold air in the air guide cavity 301, and further facilitating the improvement of the uniformity of the distribution of the cold air in the air guide cavity 301.

[0148] In some possible embodiments of the present application, the ice maker 300 can further include a driving component 370 configured to drive the ice making tray 310 to rotate. In this way, when the water in the ice cells of the ice making tray 310 is frozen, the driving component 370 drives the ice making tray 310 to rotate and twist, so that the ice cubes fall off from the ice making tray 310.

[0149] In combination Figure 7 In some embodiments, the driving component 370 is fixed to the side of the first plate portion 341 facing the second plate portion 342, so that the driving component 370 is located in the air guide cavity 301. The driving component 370 and the first plate portion 341 can be relatively sealed to avoid the cold air flowing to the chamber below the ice making tray without passing through the ice making tray. The driving component 370 and the ice making tray 310 form a second air guide gap 3022.

[0150] In the embodiments of the present application, the driving component 370 is arranged in the air guide cavity 301, so that the structure of the ice maker 300 is compact, the appearance is regular, and the assembly is facilitated. Moreover, the arrangement of the driving component 370 makes the port of the air supply air duct 320 spaced apart from the ice making tray 310, so that the cold air sent by the air supply air duct 320 can first diffuse and distribute in the air guide cavity 301 above the driving component 370, thereby improving the uniformity of the distribution of the cold air on the ice making tray 310.

[0151] In combination Figure 8 In other embodiments, the driving component 370 is fixed to the side of the first plate portion 341 away from the second plate portion 342, so that the driving component 370 is located outside the air guide cavity 301, and the second air guide gap 3022 is formed between the first plate portion 341 and the ice making tray 310. The first plate portion 341 is provided with a through hole, so that the driving component 370 can pass through the through hole and be connected with the ice making tray 310 to drive the ice making tray 310 to rotate.

[0152] In the embodiments of the present application, the driving member is arranged outside the air guiding cavity 301, so that the space in the air guiding cavity 301 is regular, the cold air flows smoothly, and the uniform distribution of the cold air is facilitated; the end turbulence caused by arranging the driving member in the air guiding cavity 301 can be reduced; the influence of the cold air on the driving member 370 can be avoided, and the service life of the driving member 370 can be prolonged.

[0153] The air guiding gap 302 in the embodiments of the present application includes a second air guiding gap 3022, and the extension direction of the second air guiding gap 3022 can be the same as that of the first air guiding gap 3021.

[0154] In some embodiments, the two ends of the second air guiding gap 3022 along the second direction respectively protrude from the two ends of the ice making tray 310 along the second direction, so that the length of the second air guiding gap 3022 along the second direction exceeds the length of the ice making tray 310 along the second direction, which can not only increase the air outlet area to increase the flow rate of the cold air, but also make the cold air on the ice making tray 310 flow out through the second air guiding gap 3022, so as to ensure the flowability of the cold air on the ice cells at the edges of the ice making tray 310, to ensure that the cold air can flow through the surfaces of all the ice cells, and to improve the uniformity of ice making.

[0155] In this way, by forming the second air guiding gap 3022 on the side of the ice making tray 310 close to the air supply duct 320, and guiding the cold air to enter the chamber below the ice making tray 310 through the second air guiding gap 3022, the problem of uneven distribution of the cold air on the side of the ice making tray 310 close to the air supply duct 320 due to poor air flow can be reduced.

[0156] Moreover, the ice making tray 310 in the embodiments of the present application is respectively provided with the first air guiding gap 3021 and the second air guiding gap 3022 on the two sides along the first direction, which can increase the position and the air volume of the cold air in the air guiding cavity 301 entering the chamber below the ice making tray 310, improve the speed of the cold air blowing over the surface of the ice making tray 310, and further improve the ice making rate. Moreover, the cold air above the ice making tray 310 can flow out of the air guiding cavity 301 from the opposite two sides of the ice making tray 310, so as to guide the cold air to flow over the ice making tray 310 from different directions, and further improve the uniformity of the distribution of the cold air on all the ice cells of the ice making tray 310.

[0157] In some embodiments of the present application, the interval size of the first air guiding gap 3021 along the first direction is greater than the interval size of the second air guiding gap 3022 along the first direction, so that the interval size of the first air guiding gap 3021 is greater, and the interval size of the second air guiding gap 3022 is smaller.

[0158] When the length of the first air guiding gap 3021 and the length of the second air guiding gap 3022 are the same, the air outlet area of the first air guiding gap 3021 is larger, and the air outlet area of the second air guiding gap 3022 is smaller. The first air guiding gap 3021 has a too large interval size, which means that the first air guiding gap 3021 has a lower air flow resistance, and the resistance of the cold air passing through the first air guiding gap 3021 can be reduced, so that the cold air in the air guiding cavity 301 can flow more to the first air guiding gap 3021, which helps to achieve a more uniform cooling effect on the entire ice making tray 310 surface and avoid the cold air being too concentrated in the area close to the air supply air duct 320.

[0159] In the embodiments of the present application, the length of the first air guiding gap 3021 and the length of the second air guiding gap 3022 are the same, and the width of the first air guiding gap 3021 is greater than the width of the second air guiding gap 3022, so that the air outlet area of the first air guiding gap 3021 is greater than the air outlet area of the second air guiding gap 3022. The length is the size of the air guiding gap along the second direction, and the width is the size of the air guiding gap along the first direction.

[0160] Since the ice making tray 310 is usually a regular rectangular disc, such a setting can not only simplify the structure in the air guiding cavity 301 and facilitate the formation of the first air guiding gap 3021 and the second air guiding gap 3022, but also make the air outlet areas of the first air guiding gap 3021 and the second air guiding gap 3022 different.

[0161] Of course, in some embodiments, the air outlet areas of the first air guiding gap 3021 and the second air guiding gap 3022 can also be made different by setting different lengths of the first air guiding gap 3021 and the second air guiding gap 3022, or by setting different lengths and widths of the first air guiding gap 3021 and the second air guiding gap 3022.

[0162] Continuing to refer to Figure 6 In some possible implementations of the present application, the air guiding shell 340 can further include a third plate portion 343 and a fourth plate portion 344, and the third plate portion 343 and the fourth plate portion 344 are oppositely and spacedly arranged along the second direction. The second direction is perpendicular to the first direction, and the plane determined by the second direction and the first direction is perpendicular to the depth direction of the ice making tray 310. The second direction can correspond to Figure 6 the Y-axis direction in the coordinate system shown in FIG. 6.

[0163] The third plate portion 343 and the fourth plate portion 344 have two ends along the first direction, one end of the third plate portion 343 and the fourth plate portion 344 along the first direction is connected with the first plate portion 341, and the other end of the third plate portion 343 and the fourth plate portion 344 along the first direction is connected with the second plate portion 342, so that the first plate portion 341, the second plate portion 342, the third plate portion 343 and the fourth plate portion 344 enclose to form a ring structure, and the ring structure is open at both ends along the depth direction of the ice tray 310.

[0164] In combination with Figure 4 and Figure 5 , the depth direction of the ice tray 310 corresponds to the Z-axis direction in the figure, that is, the height direction of the door body 200.

[0165] In some embodiments, the air guide shell 340 can further include a top plate portion 345 fixed to the top of the first plate portion 341, the second plate portion 342, the third plate portion 343 and the fourth plate portion 344. Among them, the top plate portion 345 can be fixed to the top of the first plate portion 341, the second plate portion 342, the third plate portion 343 and the fourth plate portion 344 by screwing, clamping or other means.

[0166] In some possible implementations, the top plate portion 345 can be integrally formed with at least one of the first plate portion 341, the second plate portion 342, the third plate portion 343 and the fourth plate portion 344. For example, the top plate portion 345 can be integrally formed with the first plate portion 341 and the second plate portion 342. In this way, the structural strength of the air guide shell 340 can be improved, and the connection gap of the air guide shell 340 can be reduced, and the air tightness of the air guide cavity 301 can be improved.

[0167] The top plate portion 345 is spaced apart from the ice tray 310 along the depth direction of the ice tray 310, and the top plate portion 345, the first plate portion 341, the second plate portion 342, the third plate portion 343, the fourth plate portion 344 and the ice tray 310 together enclose to form a relatively sealed air guide cavity 301.

[0168] In some embodiments of the present application, the air guide shell 340 is formed by arranging the third plate portion 343, the fourth plate portion 344 and the top plate portion 345, and together with the first plate portion 341 and the second plate portion 342 to enclose a downwardly open cavity. The top plate portion 345 is opposite to and spaced apart from the ice tray 310 along the depth direction of the ice tray 310. In this way, the air guide shell 340 and the ice tray 310 enclose to form a relatively sealed air guide cavity 301, and the air guide cavity 301 diffuses and distributes the cold air sent by the air supply duct 320, thereby improving the uniformity of the distribution of the cold air on all ice cells of the ice tray 310.

[0169] Continuing to refer to Figure 6In some embodiments of the present application, the third air guiding gap 3023 is formed between the ice making tray 310 and the third plate portion 343, and between the ice making tray 310 and the fourth plate portion 344, respectively. The air guiding gap 302 includes the third air guiding gap 3023.

[0170] The third air guiding gap 3023 can extend along the first direction. The two ends of the third air guiding gap 3023 along the first direction protrude from the two ends of the ice making tray 310 along the first direction, so that the length of the third air guiding gap 3023 along the first direction exceeds the length of the ice making tray 310 along the first direction. This not only increases the air outlet area to increase the flow rate of the cold air, but also allows the cold air on the ice making tray 310 to be dispersed through the third air guiding gap 3023, ensuring the flow of cold air on the edge ice cells of the ice making tray 310.

[0171] The two ends of the third air guiding gap 3023 extending along the first direction can be in communication with the first air guiding gap 3021 and the second air guiding gap 3022, respectively. In this way, the two third air guiding gaps 3023, the first air guiding gap 3021 and the second air guiding gap 3022 form a ring-shaped air outlet gap, so that the cold air can be guided out from the edges of the ice making tray 310 in all directions, and the edge effect can be eliminated, so that the ice cells at the edges of the ice making tray 310 can be cooled as evenly as the middle ice cells. Moreover, the ring-shaped air outlet gap allows the cold air in the air guiding cavity 301 to flow out in all directions from the ice making tray 310, ensuring that cold air flows through all ice cells on the ice making tray 310, thereby improving the uniformity of the cold air distribution and further improving the ice making efficiency and consistency.

[0172] In some possible implementations of the present application, the spacing of the third air guiding gap 3023 along the second direction gradually increases from the first plate portion 341 to the second plate portion 342 along the first direction. That is, the spacing of the third air guiding gap 3023 gradually increases in the direction away from the air supply duct 320, so that the resistance of the third air guiding gap 3023 gradually decreases and the amount of cold air flowing out of the third air guiding gap 3023 gradually increases. That is, the farther away from the air supply duct 320, the more cold air flows out of the third air guiding gap 3023, which increases the flow path of the cold air in the air guiding cavity 301, so that the cold air is more dispersed in the air guiding cavity 301, thereby improving the uniformity of the cold air distribution on all ice cells on the ice making tray 310.

[0173] In some embodiments, the air guiding shell 340 can be formed by a part of the shell of the ice maker 300, so that the structure of the air guiding shell 340 is compact and easy to install.

[0174] In some embodiments, the air guide shell 340 can include at least part of the outer shell of the ice maker 300 and the inner liner 210 of the door body 200, so that the overall volume of the ice maker 300 can be reduced and the installation space of the ice maker 300 can be reduced.

[0175] In some specific implementations, the first plate portion 341, the second plate portion 342, the third plate portion 343, the fourth plate portion 344, and the top plate portion 345 of the air guide shell 340 can be formed separately by the outer shell of the ice maker 300, can be formed separately by the inner liner 210 of the door body 200, or can be formed jointly by the outer shell of the ice maker 300 and the inner liner 210 of the door body 200.

[0176] The specific structure of the air guide shell 340 in some embodiments will be described below with reference to the accompanying drawings, which should be understood as an exemplary description of the air guide shell 340 and not as a limitation on the specific structure of the air guide shell 340.

[0177] In combination Figure 2 In some embodiments, the inner liner 210 of the door body 200 is recessed away from the refrigeration compartment 101 to form a recessed mounting portion 211. The ice maker 300 is mounted in the recessed mounting portion 211, so that the ice maker 300 can be embedded in the door body 200, and the ice blocks can be taken out without opening the door body 200 through structural arrangement.

[0178] In combination Figure 2 And Figure 13 The recessed mounting portion 211 can include a top side wall 2111 and a bottom side wall 2114 opposite to each other and spaced apart along the height direction of the door body 200, and the mounting portion can further include a first side wall 2112 and a second side wall 2113 opposite to each other and spaced apart along the width direction of the door body 200, and the first side wall 2112 is close to the hinged side of the door body 200 and the cabinet 100. The top side wall 2111, the bottom side wall 2114, the first side wall 2112, and the second side wall 2113 jointly form an annular cavity.

[0179] The recessed mounting portion 211 can further include an outer side wall 2115 opposite to the rear wall of the refrigeration compartment 101 when the door body 200 closes the refrigeration compartment 101. The outer side wall 2115 is connected to the top side wall 2111, the bottom side wall 2114, the first side wall 2112, and the second side wall 2113, respectively.

[0180] In some embodiments, the outer side wall 2115, the top side wall 2111, the bottom side wall 2114, the first side wall 2112, and the second side wall 2113 are integrally formed as one piece, which facilitates the integral forming of the inner liner 210 of the door body 200 and is simple to process.

[0181] The ice making tray 310 is spaced apart from the bottom side wall 2114, forming a chamber below the ice making tray 310.

[0182] In some embodiments, the refrigerator can include an ice making door installed on one side of the recessed mounting portion 211 facing the refrigeration compartment 101 to shield the ice maker 300 and the like structure in the recessed mounting portion 211.

[0183] In some embodiments of the present application, the air supply duct 320 is installed on the first side wall 2112, the first opening is provided on the inner side of the first side wall 2112 facing the second side wall 2113, the second opening is configured on the outer side of the first side wall 2112 away from the second side wall 2113, and the air supply duct 320 is installed between the first opening and the second opening.

[0184] The second opening is used to communicate with the first air duct in the cabinet 100, and a sealing ring can be provided on the edge of the second opening to improve the sealing performance of the connection between the first side wall 2112 and the first air duct. In this way, the cold air in the evaporation chamber enters the air supply duct 320 through the first air duct and the second opening, and then enters the air guide shell 340.

[0185] The second opening is spaced apart from the top end of the door body 200, which can ensure the structural strength and stability of the door body 200, and also facilitates the connection between the second opening and the first air duct on the side of the cabinet 100.

[0186] In some embodiments, the return air duct 330 is installed on the first side wall 2112, which facilitates shortening the return air path.

[0187] Referring to Figure 9 and Figure 10 The ice maker 300 can include an ice tray shell 350, wherein the ice tray shell 350 is open on both sides along the depth direction of the ice making tray 310, facilitating the installation and maintenance of the ice making tray 310, and the like.

[0188] The ice tray shell 350 is fixed to the recessed mounting portion 211, for example, the ice tray shell 350 is fixed to the recessed mounting portion 211 by screws, so that the installation of the ice maker 300 is stable and reliable. The ice making tray 310 is rotatably installed in the ice tray shell 350, facilitating the ice making tray 310 to flip and release ice.

[0189] The ice tray shell 350 is spaced apart from the top end of the recessed mounting portion 211, so that the electrical connection terminals, the water inlet mechanism of the ice making tray 310, and the like can be provided above the ice tray shell 350; and the area of the diffusion space formed above the ice tray shell 350 is larger than that of the ice making tray 310, facilitating the diffusion and distribution of cold air.

[0190] Continuing to refer to Figure 4 and Figure 9In some embodiments, the first opening is located above the ice tray shell 350, so that the air supply air duct 320 blows air towards the air guide cavity 301 part above the ice tray shell 350, and the cold air flows to the ice making tray 310 in the ice tray shell 350 under the action of gravity and natural diffusion, which is beneficial to the diffusion and distribution of the cold air and helps to improve the uniformity of the distribution of the cold air in all ice cells.

[0191] In some embodiments, in combination with Figure 9 and Figure 10 The ice maker 300 can further include a wind blocking piece 360 located on the side of the ice making tray 310 facing the refrigeration compartment 101, and the wind blocking piece 360 is fixedly connected with the ice tray shell 350 and the recessed mounting part 211 respectively.

[0192] The ice tray shell 350, the wind blocking piece 360 and the recessed mounting part 211 jointly form the air guide cavity 301; the air guide shell part 340 includes part of the ice tray shell 350, the wind blocking piece 360 and the recessed mounting part 211.

[0193] In some embodiments of the present application, the air guide shell part 340 is provided with the ice tray shell 350, so that the ice making tray 310 is installed in the ice tray shell 350, which facilitates the overall assembly of the ice tray shell 350 and the ice making tray 310 to the recessed mounting part 211; the ice tray shell 350 and the top end of the recessed mounting part 211 have a gap, which can reserve installation positions for the electrical connection terminals of the ice maker 300 and the water inlet mechanism of the ice making tray 310, and also allows the cold air sent by the air supply air duct 320 to diffuse and distribute in the space above the ice tray shell 350 and then flow to the surface of the ice making tray 310, which helps to improve the uniformity of the distribution of the cold air in all ice cells of the ice making tray 310.

[0194] The air guide shell part 340 of the embodiments of the present application is provided with the wind blocking piece 360 to close the side of the air guide cavity 301 facing the refrigeration compartment 101, and also facilitates the disassembly of the wind blocking piece 360 for maintenance of the ice making tray 310, the driving part 370 and the like.

[0195] In the above structure, the shell plate of the ice tray shell 350 facing the air supply air duct 320 in the first direction is connected with the first side wall 2112 and is relatively sealed therebetween, and the shell plate of the ice tray shell 350 facing the air supply air duct 320 in the first direction and the first side wall 2112 above it jointly form the first plate part 341 of the air guide shell part 340. The first air guide gap 3021 is formed between the shell plate of the ice tray shell 350 facing the air supply air duct 320 in the first direction and the ice making tray 310.

[0196] The ice tray shell 350 is connected to the second side wall 2113 in the first direction away from the shell plate of the air supply air duct 320, and the two are relatively sealed. The ice tray shell 350 and the second side wall 2113 above it in the first direction away from the shell plate of the air supply air duct 320 jointly form the second plate part 342 of the air guide shell 340. Since the driving part 370 is located in the ice tray shell 350, the driving part 370 and the ice making tray 310 form a second air guide gap 3022.

[0197] The ice tray shell 350 is connected to the outer side wall 2115 in the second direction away from the air baffle 360, and the two are relatively sealed. The ice tray shell 350 and the outer side wall 2115 above it in the second direction away from the shell plate of the air baffle 360 jointly form the third plate part 343 of the air guide shell 340.

[0198] The ice tray shell 350 is connected to the air baffle 360 in the second direction towards the shell plate of the air baffle 360, and the two are relatively sealed. The ice tray shell 350 and the air baffle 360 in the second direction jointly form the fourth plate part 344 of the air guide shell 340. The two shell plates of the ice tray shell 350 in the second direction form a third air guide gap 3023 between the ice making tray 310.

[0199] The top side wall 2111 of the recessed mounting part 211 forms the top plate part 345 of the air guide shell 340.

[0200] Through the above arrangement, the ice making tray 310 and the driving part 370 are installed in the ice tray shell 350, and the three form an ice making assembly, which is convenient for overall installation, disassembly, maintenance, etc.

[0201] Through the above arrangement, the air guide cavity 301 includes a first cavity part and a second cavity part connected in communication. The first cavity part is formed by the ice tray shell 350 and the ice making tray 310, and the second cavity part is located at the upper part of the ice tray shell 350 and is formed by part of the side wall of the recessed mounting part 211. The air supply air duct 320 is arranged on the first side wall 2112 of the second cavity part. In this way, the cold air sent in by the air supply air duct 320 first enters the second cavity part, diffuses in the second cavity part, and flows to the first cavity part in the ice tray shell 350, so that the air guide cavity 301 covers all the ice cells of the ice making tray 310, which helps to improve the uniformity of the distribution of cold air on all the ice cells.

[0202] Moreover, since the driving part 370 is installed in the ice tray shell 350, the projection area of the second cavity part in the first plane is greater than the projection area of the ice making tray 310 in the first plane, so that the second cavity part can cover all the ice cells of the ice making tray 310, ensuring that all the ice cells can be covered by cold air for freezing. Moreover, the cold air in the second cavity part has the effect of gathering cold air towards the ice making tray 310 in the process of flowing to the surface of the ice making tray 310, further ensuring that all the ice cells can be covered by cold air.

[0203] wherein the first plane is a plane determined by the first direction and the second direction, which can correspond to Figure 9 the XY plane in

[0204] With reference back to Figure 11 , Figure 12 and Figure 13 , the wind shield 360 can include a wind shield plate portion 361 opposite the outer sidewall 2115 of the recessed mounting portion 211 along the second direction and having a gap therebetween, the wind shield plate portion 361 enclosing a side of the air guide cavity 301 facing away from the outer sidewall 2115.

[0205] The wind shield 360 can include a top turn-up edge 362 connected to a top end of the wind shield plate portion 361 and located on a side of the wind shield plate portion 361 facing away from the air guide cavity 301. The top turn-up edge 362 abuts the top sidewall 2111 of the recessed mounting portion 211, such that a face contact is formed between the top of the wind shield 360 and the top sidewall 2111, which helps to improve the air tightness of the air guide cavity 301.

[0206] In some embodiments, the top turn-up edge 362 is fixedly connected to the top sidewall 2111 by a screw, which helps to improve the reliability and stability of the installation of the wind shield 360.

[0207] In some embodiments, the wind shield 360 can further include a side turn-up edge 363 connected to a side of the wind shield plate portion 361 facing away from the air supply duct 320 and located on a side of the wind shield plate portion 361 facing away from the air guide cavity 301. The side turn-up edge 363 is opposite the second sidewall 2113 of the recessed mounting portion 211, and the side turn-up edge 363 abuts the second sidewall 2113, such that a face contact is formed between a side of the wind shield 360 along the first direction and the second sidewall 2113, which helps to improve the air tightness of the air guide cavity 301.

[0208] In some embodiments, the side turn-up edge 363 is fixedly connected to the second sidewall 2113 by a screw, which helps to further improve the reliability and stability of the installation of the wind shield 360.

[0209] With reference back to Figure 13 , in some embodiments, a fixing portion 2116 protruding outward is formed on a side of the first sidewall 2112 facing the air guide cavity 301, the fixing portion 2116 being used at least for fixing the wind shield 360. An end of the wind shield plate portion 361 of the wind shield 360 along the first direction facing away from the side turn-up edge 363 is in face contact with the fixing portion 2116, which further improves the air tightness of the air guide cavity 301.

[0210] The wind deflector part 361 is fixedly connected with the fixed part 2116 at one end away from the side turning edge 363 in the first direction, for example, by screwing, so that the top side and both sides of the wind deflector part 361 in the first direction are fixedly connected with the door liner 210, which not only improves the reliability and stability of the installation of the wind deflector 360, but also helps to balance the uniformity of the stress of the wind deflector 360, reduces the deformation of the wind deflector 360 due to uneven stress, and further affects the sealing of the air guide cavity 301.

[0211] With reference to the foregoing Figure 11 In some embodiments, the wind deflector 360 can further include a reinforcing rib plate 364 connected with the top turning edge 362 and the wind deflector part 361, respectively, which helps to improve the structural strength of the wind deflector 360.

[0212] Of course, the reinforcing rib plate 364 can be provided with a plurality of reinforcing rib plates 364, which can be arranged at intervals in the first direction to further improve the structural strength of the wind deflector 360.

[0213] In combination with Figure 9 , Figure 10 and Figure 12 In some embodiments, the wind deflector part 361 is provided with a buckle 365 on the side of the wind deflector part 361 facing the air guide cavity 301, and the buckle 365 is located at the bottom end of the wind deflector part 361. The buckle 365 is connected with the ice tray shell 350, so that the wind deflector 360 and the ice tray shell 350 are preliminarily fixed, providing initial positioning for the fixed connection between the wind deflector 360 and the door liner 210, and improving the convenience of assembly of the wind deflector 360.

[0214] Moreover, the connection between the wind deflector 360 and the ice tray shell 350 is stable, which ensures the airtightness between the wind deflector 360 and the ice tray shell 350. Moreover, the two sides of the wind deflector 360 in the first direction and the two sides in the height direction of the door body 200 are fixed, which helps to further improve the stability of the installation of the wind deflector 360.

[0215] In some embodiments, the buckle 365 can include a connecting arm and a connecting head, the connecting arm connecting the connecting head and the wind deflector part 361, and the connecting head being located below the connecting arm and being connected with the ice tray shell 350.

[0216] In some embodiments, the buckle 365 can be provided with a plurality of buckles 365, which can be arranged at intervals in the first direction.

[0217] A matching plate 366 is arranged between the two adjacent buckles 365, which can be flush with the connecting arm of the buckle 365, so that the matching plate 366 is in contact with the top surface of the ice tray shell 350, which helps to improve the airtightness of the connection between the wind deflector 360 and the ice tray shell 350.

[0218] In combination Figure 6 In some embodiments of the present application, the air supply duct 320 has a first air inlet 321, which is directed towards the air guide cavity 301 and is located at one side of the air guide cavity 301 along the first direction.

[0219] The air supply duct 320 also has a second air inlet 322, which is configured to communicate with the chamber in which the evaporator of the refrigeration system is located.

[0220] The air supply duct 320 is configured to form a passage for cold air, so that the cold air can enter from the second air inlet 322 and flow out of the air supply duct 320 from the first air inlet 321.

[0221] The ice-making tray 310 has a center line along the first direction, so that the ice-making tray 310 can be symmetrical with respect to the center line.

[0222] The first air inlet 321 is symmetrically arranged with respect to the center line, so that the cold air blown out of the first air inlet 321 along the second direction is symmetrical along the center line, improving the uniformity of the distribution of the cold air on the ice tray along the second direction.

[0223] In some embodiments of the present application, the first air inlet 321 has a first size along the second direction.

[0224] The ice-making tray 310 has a second size along the second direction.

[0225] The ratio of the first size to the second size is greater than 4 / 5, so that the size of the first air inlet 321 along the second direction is greater than 80% of the size of the ice-making tray 310 along the second direction, which can make the first air inlet 321 cover most of the ice-making tray 310 along the second direction, not only improving the uniformity of the distribution of the cold air in the air guide cavity 301, but also improving the air supply amount, thereby facilitating the formation of a higher air pressure in the air guide cavity 301 compared to the chamber below the ice-making tray 310, improving the flow rate of the cold air, and thereby improving the ice-making efficiency.

[0226] In embodiments of the present application, the first size is smaller than the size of the air guide cavity 301 along the second direction, that is, the first air inlet 321 is located inside the air guide cavity 301, avoiding the first air inlet 321 extending outside the air guide cavity 301.

[0227] The second direction is perpendicular to the first direction, and the plane determined by the second direction and the first direction is perpendicular to the depth direction of the ice-making tray 310.

[0228] In combination Figure 14In some possible implementation manners of the present application, the part of the second air inlet 322 and the part of the first air inlet 321 are opposite to each other and have a spacing in the first direction, so that the second air inlet 322 can be matched with the second opening arranged on the first side wall 2112 of the door liner 210, and the second air inlet 322 can be located above the ice making tray 310, so as to facilitate the downward flow of cold air to cover the ice making tray 310. The part of the second air inlet 322 and the part of the first air inlet 321 are opposite to each other and have a spacing in the first direction, so that the cold air of the second air inlet 322 can directly enter the first air inlet 321 through the air supply air duct 320, the flow resistance of the cold air in the air supply air duct 320 can be reduced, and the smoothness of the cold air entering the air guide cavity 301 can be improved.

[0229] With reference to Figure 15 And Figure 16 In some embodiments of the present application, the first air inlet 321 and the second air inlet 322 can both be rectangular openings, which are convenient for processing and installation.

[0230] The length direction of the first air inlet 321 can be parallel to the second direction, so that the first air inlet 321 covers a larger distance of the air guide cavity 301 in the second direction, and the air supply towards the air guide cavity 301 is facilitated.

[0231] The length direction of the second air inlet 322 can be parallel to the height direction of the door body 200, so that the second air inlet 322 has a larger area without having to be provided with a larger width, and is matched with the structure that the first side wall 2112 of the door liner 210 has a larger size in the height direction of the door body 200 and a smaller size in the thickness direction of the door body 200.

[0232] In some possible embodiments, the inner surface of the air supply air duct 320 is a curved surface, or the inner surface of the air supply air duct 320 includes a curved surface and a flat surface, so that the inner surface of the air supply air duct 320 is relatively smooth, which facilitates the reduction of the flow resistance of the cold air in the air supply air duct 320 and the reduction of the loss of the cold air flowing through the air supply air duct.

[0233] With reference to Figure 15 And Figure 16 In some embodiments, the air supply air duct 320 can include a first wall portion 323 and a second wall portion 324, and the first wall portion 323 and the second wall portion 324 are opposite to each other and have a spacing in the height direction of the door body 200.

[0234] The air supply air duct 320 can further include a third wall portion 325 and a fourth wall portion 326, and the third wall portion 325 and the fourth wall portion 326 are opposite to each other and have a spacing, and the top side of the third wall portion 325 and the fourth wall portion 326 are connected with the first wall portion 323, and the bottom side of the third wall portion 325 and the fourth wall portion 326 are connected with the second wall portion 324.

[0235] The first wall portion 323, the second wall portion 324, the third wall portion 325 and the fourth wall portion 326 are all curved wall portions, which are beneficial to reduce the air resistance of the air supply air duct 320.
