Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, and in particular to a refrigerator. Background Art

[0002] Refrigerators are an essential household appliance. As living standards improve, demand for refrigerator functionality is also increasing. Some refrigerators are equipped with ice makers to meet users' ice needs.

[0003] In some refrigerators, an ice maker is provided on the door, and an ice storage box is provided below the ice maker. In the related art, the ice storage box is detachably mounted on the inner side of the door, and the user takes ice by opening the door and removing the ice storage box.

[0004] However, the disassembly and assembly structure of the ice storage box is complicated, and the convenience of taking out ice is poor. Summary of the Invention

[0005] The present application provides a refrigerator that can take ice out of an ice maker door, has a simple structure, and is convenient for taking ice out.

[0006] An embodiment of the present application provides a refrigerator, comprising:

[0007] A box body having a storage compartment;

[0008] a door body, rotatably connected to the box body, and used for opening or closing the storage compartment;

[0009] an ice maker, mounted on a mounting bracket on the inner side of the door, for making ice;

[0010] An ice storage box is detachably mounted on the mounting bracket and is located below the ice maker; the top side of the ice storage box is open for receiving ice cubes released from the ice maker;

[0011] The mounting bracket is provided with an arc-shaped track groove and a mounting groove, and the ice storage box is provided with a matching portion and a rotating shaft portion; the matching portion matches the arc-shaped track groove, the rotating shaft portion rotates in conjunction with the mounting groove, and the rotating shaft portion is located below the matching portion;

[0012] The ice storage box has a separation state, a pre-installed state, an ice storage state and an ice removal state; wherein,

[0013] The ice storage box is pre-installed from the separated state to a first position of the door body along a direction inclined relative to the door body, forming the pre-installed state; in the pre-installed state, a first inclined angle is formed between the ice storage box and the door body;

[0014] The ice storage box starts from the first position of the pre-installed state, and the matching portion moves in an arc along the arc track groove in a first direction to a second position around the rotating shaft portion as the center of the circle, thereby forming the ice storage state in which the ice storage box and the door body are parallel to each other;

[0015] The ice storage box starts from the second position of the ice storage state, and the matching portion moves in an arc along the arc track groove in the second direction to a third position around the rotating shaft portion as the center of the circle, and the ice storage box and the door body form an ice removal state with a second inclined angle;

[0016] The second direction is opposite to the first direction.

[0017] Thus, in the refrigerator embodiment of the present application, the ice storage bin is located below the ice maker, allowing it to directly receive ice cubes dropped from the ice maker, eliminating the need for an ice cube transfer mechanism and resulting in a simple structure. The ice storage bin is rotatably and removably mounted to a mounting bracket on the inside of the door. This allows the ice storage bin to be rotated relative to the door for easy and convenient ice retrieval through the door, and can also be removed from the door for ice retrieval and maintenance, providing flexible and diverse ice retrieval methods. Furthermore, the ice storage bin eliminates the need for an ice blade mechanism or ice stirring mechanism, simplifying the internal structure of the ice storage bin and thereby increasing its ice storage capacity.

[0018] The mounting bracket is provided with an arc-shaped track groove and a mounting groove, and the ice storage bin is provided with a mating portion and a rotating shaft portion. The ice storage bin has a detached state, a pre-installed state, an ice storage state, and an ice removal state. The rotating shaft portion rotates in conjunction with the mounting groove, and the mating portion moves in conjunction with the arc-shaped track groove to achieve the switching of the ice storage bin between the pre-installed state, ice storage state, and ice removal state. When the mating portion is disengaged from the arc-shaped track groove and the rotating shaft portion is disengaged from the mounting groove, the ice storage bin can be removed from the mounting bracket, resulting in a simple assembly and disassembly structure and high operational convenience.

[0019] The rotation direction of the ice storage box from the ice storage state to the ice removal state or the pre-installation state is opposite to the rotation direction of the ice storage box from the pre-installation state to the ice storage state, so that the opening and closing of the ice storage box present opposite operation paths. Only the reverse action is required to switch the state, which is in line with the human body's inertial cognition of the switch action, making the ice removal operation more convenient and helping to reduce misoperation.

[0020] In the pre-installed state, the ice bank is tilted relative to the door, forming a first tilt angle. This allows the upper portion of the ice bank to avoid interference from the ice maker when the ice bank is installed from the detached state to the pre-installed state. In the pre-installed state, the lower portion of the ice bank can be positioned without interference from the ice maker, with the mating portion entering the arcuate track groove and the rotating shaft portion entering the installation groove, forming a support point for the ice bank. Further rotation of the upper portion of the ice bank allows the ice bank to completely avoid the ice maker, allowing installation. Furthermore, because the pre-installation process for the ice bank is blind, the first tilt angle allows the upper portion of the ice bank to avoid the ice maker, providing a larger installation margin and eliminating the need for precise docking, making installation smoother and more convenient.

[0021] The ice storage box is tilted relative to the door body when ice is being taken out, and forms a second tilt angle, so that the opening of the ice storage box is exposed outward from the bottom of the ice maker and faces the user, removing the ice maker's obstruction to the ice storage box, making it easier for users to take ice, reducing the difficulty of taking ice for users, and improving the convenience of taking ice for users.

[0022] In some embodiments of the present application, the second tilt angle is greater than the first tilt angle.

[0023] First, when the ice storage bin switches from the ice storage state to the ice removal state, it moves a further distance than in the pre-installed state. This allows the ice storage bin to avoid the opening in the pre-installed state when in the ice removal state. As a result, the ice storage bin is confined within the arc-shaped trajectory groove in the ice removal state, preventing the ice storage bin from moving out of the pre-installed opening and falling out. This further stabilizes the ice storage bin in the ice removal state, eliminating the need for the user to manually restrain the ice storage bin, and further improving the convenience of ice removal. Second, the second tilt angle of the ice storage bin in the ice removal state is greater than the first tilt angle in the pre-installed state, resulting in a greater tilt angle of the ice storage bin in the ice removal state, a more pronounced tilt of the ice storage bin opening, and greater convenience in ice removal. Ice cubes are more likely to slide toward the opening of the ice storage bin due to gravity, reducing the need for manual digging, which further improves the convenience of ice removal.

[0024] In addition, the second tilt angle of the ice storage box in the ice removal state is greater than the first tilt angle in the pre-installed state, so that the ice storage box can serve as a safety buffer for disassembling the ice storage box in the ice removal state, providing a fault tolerance mechanism for the disassembly and installation of the ice storage box.

[0025] In some embodiments of the present application, the groove wall of the arc-shaped trajectory groove includes: a first arc-shaped wall and a second arc-shaped wall radially opposite to each other along the arc-shaped trajectory groove, the first arc-shaped wall is located above the second arc-shaped wall and is provided with a first opening for the mating portion to enter and exit the arc-shaped trajectory groove;

[0026] The groove wall of the arc-shaped trajectory groove further includes a first end wall and a second end wall, wherein the first end wall and the second end wall are respectively connected to two ends of the first arc-shaped wall and the second arc-shaped wall in the extension direction;

[0027] When the ice storage box is in the ice storage state, the matching portion abuts against the first end wall;

[0028] When the ice storage box is in the ice taking state, the matching portion abuts against the second end wall.

[0029] The arcuate track groove of the embodiment of the present application is provided with a first arcuate wall and a second arcuate wall to limit the arcuate direction of the arcuate track groove. The first and second end walls are provided at both ends of the first and second arcuate walls in the direction of extension to limit the position of the mating portion along the first and second directions. The first and second arcuate walls, in combination, restrict the degree of freedom of the mating portion in the ice storage state and ice removal state, thereby improving the stability of the ice storage box in both the ice storage state and the ice removal state. In the ice removal state, the position of the ice storage box is stable, which helps to improve the convenience of ice removal.

[0030] In some embodiments of the present application, the first arc-shaped wall has a first end surface and a second end surface that are opposite to each other and spaced apart along its extension direction, and the first opening is formed between the first end surface and the second end surface; the first end surface is close to the first end wall, and the second end surface is close to the second end wall;

[0031] Along the extending direction of the first arc-shaped wall, there is a first interval between the first end surface and the first end wall, and there is a second interval between the second end surface and the second end wall; the second interval is smaller than the first interval.

[0032] This arrangement places the first opening near the first end wall, placing it closer to the ice removal state and, consequently, positioning the first opening higher than the second end wall along the height of the door. Consequently, when the ice bank transitions from a detached state, the mating portion passes through the first opening and enters the arcuate track groove in a direction inclined relative to the door, forming a pre-installed state. Furthermore, as the ice bank slides from the first opening along the arcuate track groove in a first direction to the first end wall, the mating portion tends to slide downward, facilitating smoother installation of the ice bank. The proximity of the first opening to the second end wall results in a relatively large first inclination angle for the ice bank, facilitating assembly and disassembly.

[0033] In some embodiments of the present application, one end of the first arc-shaped wall forming the first end surface is connected to a first inclined wall, and the first inclined wall extends obliquely toward one side of the second end surface;

[0034] The orthographic projection of the first inclined wall on the horizontal plane of the door body covers the first opening.

[0035] In this embodiment of the present application, a first inclined wall is connected to one end of the first curved wall forming the first end surface, thereby restricting the mating portion from entering the curved track groove through the first opening. This prevents the mating portion from moving outside the curved track groove when the ice bank is pre-installed in an inclined direction relative to the door. Furthermore, the inclined configuration of the first inclined wall guides the mating portion through the first opening into the curved track groove, thereby improving the convenience of assembly and disassembly of the ice bank.

[0036] In some embodiments of the present application, the first end surface is connected to and coplanar with a wall surface of the first inclined wall facing the first opening.

[0037] In this way, the inclination angle of the first end face and the wall surface of the first inclined wall facing the first opening is the same, thereby making the connection between the wall surface of the first inclined wall facing the first opening and the first end face smoother, which helps to improve the smoothness of the mating part entering the arc trajectory groove along the first inclined wall through the first opening, and avoids the mating part from getting stuck at the first end face and affecting the convenience of installation.

[0038] In some embodiments of the present application, the mounting slot is configured to form a second opening facing upward, so that the rotating shaft portion can be installed into the mounting slot through the second opening, or removed from the mounting slot through the second opening;

[0039] The groove wall of the installation groove is located on the side of the second opening facing the door body and is connected with a second inclined wall, and the second inclined wall extends to and is connected to the outer side of the end of the arc-shaped track groove away from the door body.

[0040] This embodiment of the present application provides a second inclined wall between the mounting slot and the arcuate track groove, providing a foolproof feature that prevents the rotating shaft from becoming stuck in the gap between the arcuate track groove and the mounting slot during installation. The second inclined wall acts as a restraint on the rotating shaft, allowing it to smoothly enter the mounting slot, thereby improving the convenience of installing the ice storage bin and removing it for ice removal.

[0041] In some embodiments of the present application, the wall surface of the second inclined wall facing the second opening is tangentially connected to the outer side surface of the groove wall of the arc-shaped trajectory groove facing away from one end of the door body.

[0042] In this way, the wall surface of the second inclined wall facing the second opening is tangently connected to the curved surface, making the wall surface of the second inclined wall facing the second opening smoother, and making the rotating shaft slide downward more smoothly under the limitation of the second inclined wall, which helps to improve the convenience of installing the ice storage box.

[0043] In some embodiments of the present application, the wall of the mounting groove includes:

[0044] The third arc-shaped wall is configured to form a rotation hole portion having an opening; the rotation hole portion is rotatably engaged with the rotation shaft portion;

[0045] an outer wall connected to one end of the third arc-shaped wall in an extending direction;

[0046] an inner side wall connected to the other end of the third arc-shaped wall in the extending direction; the inner side wall is closer to the door body than the outer side wall; the inner side wall is connected to the second inclined wall;

[0047] The outer wall and one end of the inner wall facing away from the third arc-shaped wall are spaced apart to form a second opening; the second opening is located above the third arc-shaped wall;

[0048] The rotating shaft portion is installed into the installation slot or removed from the installation slot through the second opening.

[0049] In the embodiment of the present application, the mounting slot wall is provided with a third curved wall to form a rotation hole. The rotation hole rotatably cooperates with the rotation shaft, allowing the ice bank to rotate relative to the door. The inner and outer walls are connected along the extension direction of the third curved wall, defining a second opening above the third curved wall. This provides a passage and restricts the rotation shaft from entering and exiting the rotation hole through the second opening.

[0050] In some embodiments of the present application, one end of the inner wall facing away from the third arc-shaped wall is connected to a second inclined wall, and the second inclined wall extends to the outside of the groove wall of the arc-shaped trajectory groove close to the edge of the door body.

[0051] In this embodiment of the present application, a second inclined wall is provided between the inner sidewall of the mounting slot and the wall of the arc-shaped track slot near the door edge. This serves as a foolproof feature, preventing the rotating shaft from becoming stuck in the gap between the arc-shaped track slot and the mounting slot during installation. The second inclined wall also acts as a restraint on the rotating shaft, allowing it to smoothly enter the mounting slot, thereby improving the convenience of installing the ice storage bin and removing it for ice removal.

[0052] In some embodiments of the present application, the rotating shaft portion includes:

[0053] A shaft body, the shaft body being rotatably engaged with the rotating hole portion;

[0054] A limiting arm is connected to the top end of the shaft body, and a side of the limiting arm facing away from the door body forms a first abutting surface, and the first abutting surface abuts against the outer wall when the ice storage box is in the ice taking state.

[0055] The rotating shaft portion of the embodiment of the present application is provided with an axle body that rotates with the rotating hole portion, allowing the ice storage box to rotate relative to the door body. The rotating shaft portion is provided with a limiting arm to limit the ice storage box's ice removal and ice storage states. The limiting arm forms a first abutment surface that abuts against the outer wall when the ice storage box is in the ice removal state. This not only limits the tilt angle of the ice storage box in the ice removal state, but also the surface contact between the limiting arm and the outer wall disperses the applied force, preventing the outer wall from being easily damaged by concentrated force, thereby helping to increase the service life of the outer wall. Moreover, the surface contact makes the outer wall's positional restriction of the ice storage box more stable and reliable, preventing the ice storage box from moving in the ice removal state, thereby helping to improve the convenience of ice removal.

[0056] In some embodiments of the present application, a first limiting groove is formed on a side of the limiting arm away from the door body, and the first limiting groove is located at an end of the first abutting surface away from the shaft body;

[0057] The outer side wall is provided with a first protrusion; when the ice storage box is in the ice taking state, the first protrusion is matched with the first limiting groove in a concave-convex manner.

[0058] The limiting arm of the embodiment of the present application limits the freedom of movement of the ice storage box along the first abutment surface in the ice taking state by setting a first limiting groove and cooperating with the first protrusion set on the outer wall, thereby limiting the rotating shaft part in the installation groove, thereby ensuring the stability of the ice storage box in the ice taking state.

[0059] In some embodiments of the present application, a second abutting surface is formed on a side of the limiting arm away from the first abutting surface; and the second abutting surface abuts against the inner side wall when the ice storage box is in the ice storage state.

[0060] In this embodiment of the present application, the limiting arm is provided with a second abutment surface that abuts against the inner sidewall to limit the position of the ice storage box when storing ice. Furthermore, the contact between the limiting arm and the inner sidewall facilitates stress dispersion, preventing stress concentration from damaging the inner sidewall or the shaft structure.

[0061] In some embodiments of the present application, the limiting arm forms a second protrusion, and the second protrusion is located at an end of the second abutting surface away from the shaft body;

[0062] A second limiting groove is formed on the inner side wall;

[0063] When the ice storage box is in the ice storage state, the second limiting groove and the second protrusion cooperate with each other in a concave-convex manner to limit the upward freedom of the ice storage box along the height direction of the door body.

[0064] In the embodiment of the present application, the cooperation between the limiting arm and the inner side wall is achieved by the second protrusion and the second limiting groove, which limits the upward freedom of the ice storage box along the height direction of the door body, and stably restricts the rotating shaft part in the installation groove, thereby preventing the ice storage box from rotating freely in the ice storage state.

[0065] In some embodiments of the present application, a portion of the first arc-shaped wall protrudes toward the second arc-shaped wall to form an elastic limiting portion; the elastic limiting portion is located on a side of the first opening facing the first end wall;

[0066] When the ice storage box is in the ice storage state, the elastic limiting portion abuts against the matching portion.

[0067] As a result, the ice storage box in the ice storage state is restricted in its upward and downward freedom along the height direction of the door body by the first curved wall, the second curved wall, the first section wall and the elastic limiting portion, and its freedom along the first direction and the second direction is restricted to ensure that the ice storage box is stably and reliably restricted in the ice storage state, thereby ensuring the stability of the ice storage state and avoiding the possibility of the ice storage box loosening due to vibrations such as the door body switch.

[0068] In some embodiments of the present application, an elastic damping member is provided on the groove wall of the arc-shaped trajectory groove, and the elastic damping member elastically abuts against the matching portion when the ice storage box is in the ice removal state to limit the freedom of the ice storage box along the first direction.

[0069] Therefore, when the ice storage box is in the ice-taking state, the elastic damping member limits the freedom of the ice storage box along the first direction, thereby preventing the ice storage box from rotating arbitrarily along the first direction when taking ice, helping to improve the stability of the ice storage box in the ice-taking state, eliminating the need for the user to fix the ice storage box with their hands, and thus helping to improve the convenience of taking ice.

[0070] In some embodiments of the present application, the refrigerator further comprises a locking mechanism, wherein the locking mechanism is located on one side of the ice storage box along the width direction of the door body and away from the hinged side of the door body;

[0071] The locking mechanism has a locking position and an unlocking position, and the locking mechanism is configured to rotate relative to the door body between the locking position and the unlocking position;

[0072] When the locking mechanism rotates to the locking position, the locking mechanism abuts against the top of the ice storage box to limit the ice storage box to the ice storage state;

[0073] When the locking mechanism rotates to the unlocking position, the locking mechanism is separated from the ice bank, so that the ice bank can rotate relative to the door body.

[0074] The embodiment of the present application provides a locking mechanism to lock the ice storage box in the ice storage state, further improving the stability of the ice storage box in the ice storage state and preventing the ice storage box from rotating due to shaking of the door body, etc. The locking mechanism can also unlock the ice storage box, allowing the ice storage box to rotate relative to the door body to remove ice.

[0075] In some embodiments of the present application, the locking mechanism rotates around a first center, and the rotating shaft portion rotates around a second center; the angle formed between the line connecting the first center and the second center and the height direction of the door body is greater than 4° and less than 15°.

[0076] In the embodiment of the present application, the line connecting the first and second center points is tilted relative to the height of the door body, maximizing the distance between the rotation center of the locking mechanism and the rotation center of the ice bank. This creates a longer moment arm, which results in a greater torque applied to the locking mechanism. According to the principle of counter-torque balance, the smaller the counter-torque applied by the locking mechanism to the ice bank, the less resistance the locking mechanism uses to restrict the rotation of the ice bank, thereby ensuring the stability of the locking mechanism in restricting the rotation of the ice bank.

[0077] In some embodiments of the present application, the second inclination angle is greater than 30° and less than 40°.

[0078] The second tilt angle β of the embodiment of the present application is greater than 30°, so that the ice storage box has a larger tilt angle, which is convenient for taking ice and reserves space for disassembly and assembly of the ice storage box.

[0079] The second tilt angle β in the embodiment of the present application is less than 40°, which can prevent the ice cubes from sliding due to the second tilt angle β being too large. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] In order to make the purpose and implementation of this application clearer, the exemplary implementation of this application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only part of the embodiments of this application, not all of the embodiments.

[0106] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0107] In the specification and claims of this application and the accompanying drawings, the terms "first," "second," "third," etc. are used to distinguish similar or similar objects or entities, and are not necessarily intended to limit a particular order or sequence, unless otherwise noted. It should be understood that the terms used in this manner are interchangeable under appropriate circumstances.

[0108] The terms "comprise," "include," and "have," and any variations thereof, are intended to cover but not exclude inclusion; for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0109] In some refrigerators, the ice maker is installed in the door, which not only reduces storage space but also allows for ice to be taken out from outside the door without opening it. This makes ice removal simple and reduces cold air leakage from the storage room.

[0110] In order to achieve ice retrieval outside the door, an ice dispensing motor is usually provided, and ice knife mechanisms, ice stirring mechanisms and other structures are also installed in the ice storage box. Not only are the structures complex and bulky, occupying a large installation space; but the ice is also prone to getting stuck when being dispensed, resulting in poor reliability and low cost performance.

[0111] In some refrigerators, an ice storage box is detachably connected to the door to simplify the structure. In this case, the user needs to open the door and remove the ice storage box to get ice. However, the assembly and disassembly structure of the ice storage box is complicated, making it difficult to get ice.

[0112] In light of this, the refrigerator embodiment of the present application eliminates the automatic ice-dispensing mechanisms, such as the ice-dispensing motor, ice-blade mechanism, and ice-stirring mechanism, thereby saving space and increasing ice storage capacity. Furthermore, the ice storage bin is designed to be both rotatable and removable, enabling ice retrieval through the door. The ice storage bin can be rotated or detached for retrieval, resulting in a simple structure and improved ice retrieval operability.

[0113] The specific structure and function of the refrigerator in the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0114] Combine Figure 1 An embodiment of the present application provides a refrigerator, which includes a box body 10, and the box body 10 is configured with a storage compartment 101 for storing items.

[0115] Multiple storage compartments 101 can be provided to expand storage space. Depending on the storage temperature of the storage compartments 101, the storage compartments 101 can include at least one refrigeration compartment and at least one freezer compartment. The internal temperature of the refrigeration compartment can be maintained between approximately 0°C and 5°C, storing items in refrigerated mode; the internal temperature of the freezer compartment can be maintained between approximately -30°C and 0°C, storing items in frozen mode.

[0116] For example, there may be two storage compartments 101, the two storage compartments 101 may be stacked vertically, or the two storage compartments 101 may be arranged side by side horizontally, one of which may be a refrigeration compartment and the other may be a freezer compartment.

[0117] The refrigerator of the embodiment of the present application may further include a refrigeration system for reducing the air temperature of the storage compartment 101. For example, the refrigeration system may be provided in the cabinet 10. The refrigeration system may include a compressor, a condenser, a throttle, and an evaporator connected in a loop.

[0118] When the refrigeration system is operating, the compressor compresses the refrigerant vapor, generating high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the throttle. The throttle reduces the pressure of the refrigerant liquid, converting the high-pressure, low-temperature refrigerant liquid to a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and causes it to boil under isobaric conditions, absorbing heat and vaporizing it to form refrigerant vapor, thereby lowering the temperature within the storage compartment 101.

[0119] The refrigerator of the embodiment of the present application may further include a door 20, which is rotatably connected to the cabinet 10 to open or close the storage compartment 101. Exemplarily, the door 20 is hinged to the cabinet 10 via a hinge.

[0120] Alternatively, each storage compartment 101 may be provided with two doors 20, which can rotate in opposite directions to open or close the storage compartment 101. For example, a door 20 is provided for each of the freezer compartment and the refrigerator compartment.

[0121] It should be noted that in the embodiment of the present application, the width direction of the door body 20 corresponds to Figure 2 In the X-axis direction, the height direction of the door body 20 corresponds to Figure 2 In the Z-axis direction, the thickness direction of the door body 20 corresponds to Figure 2 Center Y-axis direction.

[0122] Combine Figure 2The refrigerator of the embodiment of the present application may further include an ice maker 100 for making ice cubes. The ice maker 100 is installed on the door body 20, reducing the space occupied by the ice maker 100 in the storage compartment 101, thereby reducing the impact of the installation of the ice maker 100 on the storage volume of the refrigerator.

[0123] The ice maker 100 may be directly mounted on the inner side of the door 20 facing the storage compartment 101. Alternatively, the ice maker 100 may be mounted on an intermediate structure so that the ice maker 100 is indirectly mounted on the inner side of the door 20 facing the storage compartment 101.

[0124] A mounting bracket 200 is provided on the inner side of the door 20 facing the storage compartment 101. Methods of connection between the mounting bracket 200 and the door 20 include, but are not limited to, snap connections and screw connections. The ice maker 100 is mounted on the mounting bracket 200, which distributes the weight of the ice maker 100 over a larger area of ​​the door 20, thereby preventing deformation of the door 20 due to localized stress concentration.

[0125] The ice maker 100 may include an ice tray, a flipping motor, and an air supply unit. The ice tray is used to hold water and is connected to the flipping motor. Driven by the flipping motor, the ice tray rotates about a horizontal axis relative to the mounting bracket 200, thereby flipping the ice tray and releasing the ice cubes. The air supply unit may be connected to the door 20 and is used to blow cold air generated by the refrigeration system toward the top of the ice tray, freezing the water in the ice tray into ice cubes.

[0126] The refrigerator of the embodiment of the present application may further include an ice storage box 300, which is detachably mounted on the inner side of the door 20 and located below the ice maker 100. The top side of the ice storage box 300 is open for receiving ice cubes ejected from the ice maker 100.

[0127] The ice bank 300 is detachably mounted on the mounting bracket 200 and is located below the ice maker 100. For example, the ice bank 300 is rotated relative to the mounting bracket 200 so that at least a portion of the opening of the ice bank 300 is moved outward from the ice maker 100 to facilitate taking ice out of the ice bank 300.

[0128] Compared with removing ice after the ice storage box 300 is detached from the mounting bracket 200, rotating the ice storage box 300 relative to the mounting bracket 200 to remove ice only requires rotating the ice storage box 300, which requires less operating force and does not require a large supporting force, making the operation more convenient.

[0129] Of course, after the ice storage box 300 of the embodiment of the present application is rotated relative to the mounting bracket 200 and detached from the mounting bracket 200, ice can be taken out and the ice storage box 300 can also be cleaned or maintained.

[0130] Continue to refer to Figure 3 In some embodiments of the present application, the mounting bracket 200 includes a mounting back plate 210, which is arranged parallel to the door body 20. The mounting back plate 210 can be fixed on the door body 20. The ways in which the mounting back plate 210 is fixed to the door body 20 include but are not limited to snap connection, screw connection, etc.

[0131] The mounting bracket 200 may further include a bottom plate 220, which is fixed to the bottom end of the mounting back plate 210 and located on the side of the mounting back plate 210 facing away from the door 20. The bottom plate 220 supports the ice bank 300. It should be noted that when the ice bank 300 rotates relative to the mounting bracket 200, the bottom plate 220 does not interfere with the ice bank 300, thereby preventing the bottom plate 220 from affecting the rotation of the ice bank 300.

[0132] The mounting bracket 200 may also include two mounting side panels 230, located on either side of the mounting back panel 210 along the width of the door 20. The two mounting side panels 230 are each secured to the bottom panel 220. The tops of the two mounting side panels 230 may be lower than the bottom of the ice maker 100 to prevent them from interfering with the installation of the ice maker 100. One mounting side panel 230 is located near the hinged side of the door 20, while the other is located near the open / close side of the door 20. The two mounting side panels 230 are used to mount the ice storage bin 300.

[0133] In this way, the mounting back plate 210, the bottom plate 220 and the two mounting side plates 230 enclose a space with top and front openings. The top opening allows the opening of the ice storage box 300 to face the ice maker 100, and the front opening faces away from the door body 20, providing space for the ice storage box 300 to rotate away from the door body 20.

[0134] In some embodiments, the mounting bracket 200 is an integrally formed piece, which is not only easy to form but also has a stable and reliable structure.

[0135] Continue to refer to Figure 3 In some embodiments of the present application, the mounting bracket 200 is provided with an arcuate track groove 240 and a mounting groove 250. The arcuate track groove 240 extends in an arc direction, guiding and limiting the rotation of the ice storage bin 300. The mounting groove 250 is connected to the ice storage bin 300 and is located below the arcuate track groove 240.

[0136] The arcuate track groove 240 has two opposing ends along its extension direction, with the first end of the arcuate track groove 240 being closer to the door body than the second end. The outer end surfaces of the first and second ends of the arcuate track groove 240 can both be curved surfaces, making the arcuate track groove 240 smoother in shape. This not only facilitates molding but also increases the arcuate track groove 240's ability to withstand stress, reducing the risk of cracking and damage due to stress concentration.

[0137] The two mounting side panels 230 are respectively provided with arc-shaped track grooves 240 on the sides facing each other, and the two mounting side panels 230 are respectively provided with mounting grooves 250 on the sides facing each other, so that the ice storage box 300 is respectively connected to the two mounting side panels 230 on both sides along the width direction of the door body 20, which helps to improve the reliability of the connection between the ice storage box 300 and the mounting bracket 200.

[0138] The two mounting side panels 230 may have grooves on their sides facing each other to form an arcuate track groove 240. Alternatively, the two mounting side panels 230 may be recessed away from each other to form an arcuate track groove 240. Alternatively, the two mounting side panels 230 may have protruding ribs on their sides facing each other, and the protruding ribs and the mounting side panels 230 may enclose the arcuate track groove 240. This avoids directly providing grooves on the mounting side panels 230, which would affect their structural strength, and also avoids the two mounting side panels 230 recessing away from each other, which would affect the outer sides of the mounting side panels 230.

[0139] The two mounting side panels 230 have grooves on their sides facing each other to form the mounting groove 250. Alternatively, the two mounting side panels 230 are recessed away from each other to form the mounting groove 250. Alternatively, the two mounting side panels 230 are provided with protruding ribs on their sides facing each other. The protruding ribs and the mounting side panels 230 form the mounting groove 250. This avoids directly providing grooves on the mounting side panels 230, which would affect the structural strength of the mounting side panels 230, and also avoids the two mounting side panels 230 recessing away from each other, which would affect the outer sides of the mounting side panels 230. Furthermore, the protruding ribs can also serve as reinforcement, helping to increase the structural strength of the mounting side panels 230.

[0140] Continue to refer to Figure 3 The ice storage box 300 is provided with a matching portion 330 and a rotating shaft portion 340 ; wherein the matching portion 330 matches with the arc track groove 240 , the rotating shaft portion 340 rotates with the mounting groove 250 , and the rotating shaft portion 340 is located below the matching portion 330 .

[0141] The ice bank 300 is provided with matching portions 330 on both sides along the width direction of the door body 20 , and the ice bank 300 is provided with rotating shaft portions 340 on both sides along the width direction of the door body 20 .

[0142] The axial direction of the rotating shaft portion 340 is parallel to the width direction of the door body 20 , so that the ice bank 300 can rotate relative to the door body 20 under the cooperation between the rotating shaft portion 340 and the mounting groove 250 .

[0143] Among them, the matching part 330 can be cylindrical, which not only has a simple structure and is easy to form; but also the contact area between the cylindrical matching part 330 and the arc-shaped trajectory groove 240 is small, which helps to reduce the friction between the matching part 330 and the arc-shaped trajectory groove 240, which can not only reduce the noise of the rotation of the ice storage box 300, but also help to improve the smoothness of the rotation of the ice storage box 300.

[0144] In the embodiment of the present application, the ice storage box 300 has a separation state, a pre-installed state, an ice storage state, and an ice removal state.

[0145] In the separated state, the ice storage box 300 is separated from the mounting bracket 200. Figure 4 The state when the ice storage box 300 is ready to be installed on the mounting bracket 200 is the pre-installed state of the ice storage box 300. Figure 5 In the ice storage state, the ice storage box 300 can receive ice cubes that fall off from the ice maker 100 to store ice cubes. Figure 6 In the ice taking state, the ice storage box 300 is connected to the mounting bracket 200, and at least a portion of the opening of the ice storage box 300 is exposed to the outside so that the user can take ice.

[0146] The ice storage box 300 is pre-installed from the separated state to the first position of the door body 20 along the direction of inclination relative to the door body 20, forming a pre-installed state; in the pre-installed state, a first inclination angle α is formed between the ice storage box 300 and the door body 20, such as Figure 4 shown.

[0147] The bottom end of the ice bank 300 is closer to the mounting bracket 200 of the door 20 than the top end, so that the ice bank 300 is pre-installed to the first position of the door 20 along the direction inclined relative to the door 20.

[0148] The ice storage box 300 is pre-installed from the separated state to the first position of the door body 20 along the first inclined direction to form a pre-installed state. The first inclined direction forms a first inclined angle α with the height direction of the door body 20.

[0149] In the embodiment of the present application, the mounting bracket 200 is arranged parallel to the door body 20, and a first tilt angle α is formed between the ice storage box 300 and the door body 20. It can be understood that a first tilt angle α is formed between the ice storage box 300 and the mounting back plate 210 of the mounting bracket 200.

[0150] Because the ice bank 300 is located below the ice maker 100, it is restricted by the ice maker 100 and cannot be installed from the height of the door. However, in the present embodiment, by setting a first tilt angle α, the ice bank 300 can be installed from the detached state to the pre-installed state at an angle relative to the door 20, allowing the upper portion of the ice bank 300 to avoid interference with the ice maker 100. In the pre-installed state, the lower portion of the ice bank 300 can be positioned without interference from the ice maker 100. The engaging portion 330 enters the arcuate track groove 240, and the rotating shaft portion 340 enters the installation groove 250, forming a support point for the ice bank 300. When the upper portion of the ice bank 300 is rotated, the ice bank 300 can completely avoid interference with the ice maker 100, allowing the ice bank 300 to be installed.

[0151] Moreover, due to the setting of the first tilt angle α, the ice storage box 300 can avoid the ice maker 100, providing a larger installation tolerance space for the ice storage box 300, without the need for precise docking, making the installation of the ice storage box 300 smoother.

[0152] like Figure 7 As shown, the arcuate track groove 240 is provided with a first opening 2401 at a first position of the door body 20 , so that the matching portion 330 can be installed into the arcuate track groove 240 or removed from the arcuate track groove 240 through the first opening 2401 along a first inclined direction.

[0153] The installation slot 250 is provided with a second opening 2501 at a first position of the door body 20 , so that the rotating shaft portion 340 can be installed into the installation slot 250 or removed from the installation slot 250 through the second opening 2501 along a first inclined direction.

[0154] When the engaging portion 330 enters the arcuate track groove 240 along the first inclined direction through the first opening 2401, the rotating shaft portion 340 is installed into the installation groove 250 through the second opening 2501, so that the ice bank 300 is in a pre-installed state. When the engaging portion 330 is removed from the arcuate track groove 240 through the first opening 2401, the rotating shaft portion 340 is removed from the installation groove 250 through the second opening 2501.

[0155] Reference Figures 7 to 10 The ice storage box 300 starts from the first position of the pre-installed state, revolves around the rotation center of the rotating shaft portion 340 as the center of the circle, and the matching portion 330 makes an arc motion along the arc-shaped trajectory groove 240 in the first direction to the second position, forming an ice storage state in which the ice storage box 300 and the door body 20 are parallel.

[0156] The first direction corresponds to Figure 7 The ice storage box 300 is parallel to the door body 20. It can be understood that the opening direction of the ice storage box 300 is perpendicular to the horizontal plane (corresponding to Figure 7XY plane) and upward. Figure 4 and Figure 5 , the ice storage box 300 rotates from the pre-installed state to the ice storage state along the first direction, and the top end of the ice storage box 300 rotates toward the mounting bracket 200.

[0157] Combine Figure 7 In the pre-installed state, a first inclined angle α is formed between the rear side wall 310 of the ice storage box 300 and the mounting back plate 210 .

[0158] Combine Figure 9 In the ice storage state, the bottom wall 320 of the ice bank 300 is parallel to and in contact with the bottom plate 220 of the mounting bracket 200, and the bottom plate 220 supports the weight of the ice bank 300. The rear side wall 310 of the ice bank 300 facing the mounting bracket 200 is parallel to the mounting back plate 210.

[0159] Continue to refer to Figure 8 and Figure 9 The front side wall of the ice storage box 300 protrudes relative to the bottom plate 220 away from the front end of the mounting back plate 210, that is, along the thickness direction of the door body 20 (corresponding to Figure 9 A notch is provided at the front end of the bottom plate 220 (in the Y-axis direction) to allow space for the ice storage box 300 to rotate.

[0160] The bottom plate 220 is provided with reinforcing ribs 221 to improve the structural strength of the bottom plate 220 and ensure the support for the ice storage box 300 .

[0161] The front end of the bottom plate 220 is provided with an inclined plate portion 222. The inclined plate portion 222 slopes downward along the thickness direction of the door body 20, from the mounting back plate 210 forward. Furthermore, the bottom wall 320 of the ice bank 300 is provided with an inclined structure that cooperates with the inclined plate portion 222 to increase the contact area between the bottom wall 320 of the ice bank 300 and the bottom plate 220, thereby enhancing the support provided by the bottom plate 220 for the ice bank 300.

[0162] The front side of the ice storage box 300 facing away from the mounting back plate 210 protrudes from the bottom plate 220, and the bottom wall 320 of the ice storage box 300 located in front of the inclined plate portion 222 is recessed downward relative to the bottom plate 220 and is flush with the reinforcing rib 221. This arrangement not only prevents the bottom surface of the ice storage box 300 from protruding from the bottom surface of the mounting bracket 200, which is conducive to ensuring the compactness of the mounting bracket 200 and the ice storage box 300, but also increases the volume of the ice storage box 300, which helps to increase the ice storage capacity of the ice storage box 300.

[0163] Combine Figures 10 to 12The ice storage box 300 starts from the second position of the ice storage state, and the rotation center of the rotating shaft portion 340 is as the center of the circle, and the matching portion 330 makes an arc motion along the arc-shaped trajectory groove 240 in the second direction to the third position, and the ice storage box 300 and the door body 20 form an ice taking state with a second inclined angle β.

[0164] Combine Figure 11 In the ice taking state, a second inclined angle β is formed between the rear side wall 310 of the ice storage box 300 and the mounting back plate 210 .

[0165] The ice storage box 300 is tilted relative to the door body 20 in the ice taking state and forms a second tilt angle β, so that the opening of the ice storage box 300 is exposed outward from the bottom of the ice maker 100 and faces the user, removing the ice storage box 300 from the ice maker 100, making it easier for the user to take ice, reducing the difficulty of the user taking ice, and improving the convenience of the user to take ice.

[0166] Starting from the second position in the ice storage state, the ice bank 300 moves in an arcuate manner about the rotation center of the rotation axis 340, and the engaging portion 330 moves in a second direction along the arcuate track groove 240 to the first position. The ice bank 300 forms a pre-installed state with a first tilt angle α between the ice bank 300 and the door 20. From the pre-installed state, the ice bank 300 can be removed from the door 20 to form a separated state. Furthermore, the engaging portion 330 continues to move in the second direction along the arcuate track groove 240 from the first position to the third position, forming a second tilt angle β between the ice bank 300 and the door 20 for ice removal.

[0167] The second tilt angle β is greater than 0° and less than 40°. For example, the second tilt angle β has an angle range greater than 0° and less than 10°; or, the second tilt angle β has an angle range greater than or equal to 10° and less than 20°; or, the second tilt angle β has an angle range greater than or equal to 20° and less than 30°; or, the second tilt angle β has an angle range greater than or equal to 30° and less than 40°.

[0168] Exemplarily, the second inclination angle β is 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 29°, 28°, 27°, 26°, 25°, 24°, 23°, 22°, 21°, 20°, etc.

[0169] The second tilt angle β of the embodiment of the present application is greater than 30°, so that the ice storage box 300 has a larger tilt angle, which makes it easier to take out ice and reserves space for disassembly and assembly of the ice storage box 300.

[0170] The second tilt angle β in the embodiment of the present application is less than 40°, which can prevent the ice cubes from sliding due to the second tilt angle β being too large.

[0171] In this embodiment of the present application, the arcuate track groove 240 has a first end and a second end along its extension direction. When the ice bank 300 is in the ice storing state, the engaging portion 330 moves to the first end of the arcuate track groove 240; when the ice bank 300 is in the ice removing state, the engaging portion 330 moves to the second end of the arcuate track groove 240. Along the height direction of the door 20, the second end of the arcuate track groove 240 is higher than the first end of the arcuate track groove 240. As the ice bank 300 moves from the ice storing state to the ice removing state, the engaging portion 330 moves from the first end of the arcuate track groove 240 along the second direction to the second end, and the engaging portion 330 moves upward in the height direction. This eliminates resistance during the opening process of the ice bank 300, preventing it from accidentally opening due to a user's inadvertent contact with the ice bank 300. The ice bank 300 can also be configured to have a gravity self-locking effect, preventing it from opening due to vibration or shaking of the door 20.

[0172] The second direction corresponds to Figure 11 The second direction is opposite to the first direction. Thus, the rotation direction of the ice bank 300 from the ice storage state to the ice removal state is opposite to the rotation direction of the ice bank 300 from the pre-installed state to the ice storage state. When the door 20 is open and the user is facing the door 20, the first direction is the side of the ice bank 300 with the top facing away from the door 20 and toward the user; the second direction is the side of the ice bank 300 with the top facing away from the user and toward the door 20. The first and second directions are opposite, resulting in opposite operating paths for opening (including rotating the ice bank 300 to the pre-installed state for removal and the ice removal state) and closing (the ice storage state) of the ice bank 300. Switching states requires only a reverse action, which conforms to the human body's inertial cognition of switch actions, making it more convenient to use and helping to reduce misoperation.

[0173] In this embodiment of the present application, the arcuate track groove 240 has a first end and a second end along its extension direction. When the ice bank 300 is in the ice storing state, the engaging portion 330 moves to the first end of the arcuate track groove 240; when the ice bank 300 is in the ice removing state, the engaging portion 330 moves to the second end of the arcuate track groove 240. Along the height direction of the door 20, the second end of the arcuate track groove 240 is higher than the first end of the arcuate track groove 240. As the ice bank 300 moves from the ice storing state to the ice removing state, the engaging portion 330 moves from the first end of the arcuate track groove 240 along the second direction to the second end, and the engaging portion 330 moves upward in the height direction. This eliminates resistance during the opening process of the ice bank 300, preventing it from accidentally opening due to a user's inadvertent contact with the ice bank 300. The ice bank 300 can also be configured to have a gravity self-locking effect, preventing it from opening due to vibration or shaking of the door 20.

[0174] The second direction corresponds to Figure 11 The second direction is opposite to the first direction. Thus, the rotation direction of the ice bank 300 from the ice storage state to the ice removal state is opposite to the rotation direction of the ice bank 300 from the pre-installed state to the ice storage state. When the door 20 is open and the user is facing the door 20, the first direction is the side of the ice bank 300 with the top facing away from the door 20 and toward the user; the second direction is the side of the ice bank 300 with the top facing away from the user and toward the door 20. The first and second directions are opposite, resulting in opposite operating paths for opening (including rotating the ice bank 300 to the pre-installed state for removal and the ice removal state) and closing (the ice storage state) of the ice bank 300. Switching states requires only a reverse action, which conforms to the human body's inertial cognition of switch actions, making it more convenient to use and helping to reduce misoperation.

[0175] The second tilt angle β is greater than the first tilt angle α, so that there is a significant difference in the tilt states of the ice storage box 300 in the ice removal state and the pre-installed state, thereby avoiding the possibility of user misoperation.

[0176] The second tilt angle β is larger, so that the opening of the ice storage box 300 is tilted more obviously when the ice is taken out. Figure 11 As shown, the user's eyes and hands can more easily reach the ice cubes through the opening of the ice storage bin 300, thereby obtaining ice. Moreover, the larger the second tilt angle β, the ice cubes in the ice storage bin 300 are more likely to slide toward the opening of the ice storage bin 300 due to gravity, reducing the need for manual scooping and improving the convenience of ice retrieval.

[0177] The first tilt angle α is small, so that the arc-shaped moving path of the ice storage box 300 from the pre-installed state to the ice storage state is small, and the ice storage box 300 in the pre-installed state can be pushed to the ice storage state with less force, reducing the installation effort.

[0178] The second tilt angle β is greater than the first tilt angle α. In this way, the tilt angle of the ice bank 300 relative to the door body 20 in the ice taking state is greater than the tilt angle of the ice bank 300 relative to the door body 20 in the pre-installed state. The arc movement path of the ice bank 300 when it is in the ice storing state and converted to the ice taking state is greater than the arc movement path of the ice bank 300 when it is in the pre-installed state. In other words, when the ice bank 300 is converted from the ice storing state to the ice taking state, it moves a further distance than the pre-installed state. As a result, the ice bank 300 can avoid the opening in the pre-installed state in the ice taking state. As a result, the ice bank 300 can be restricted in the arc track groove 240 in the ice taking state, preventing the ice bank 300 from moving out of the opening in the pre-installed state and falling off. As a result, the structure of the ice bank 300 in the ice taking state is more stable, and the user does not need to manually restrict the ice bank 300, further improving the convenience of ice taking.

[0179] Furthermore, when the ice bank 300 transitions from the ice storage state to the pre-installed state, even if the user applies excessive force, the ice bank 300 can be rotated to the ice removal state and restrained, maintaining a stable connection with the mounting bracket 200 and preventing the ice bank 300 from accidentally falling off the door 20. The ice removal state serves as a safety buffer for removing the ice bank 300. In other words, the ice removal state of the ice bank 300 also serves as a fault-tolerant mechanism, preventing the ice bank 300 from accidentally falling off due to excessive rotation during removal. This prevents the ice bank 300 from accidentally falling off due to excessive rotation during removal. This prevents the ice bank 300 from falling off directly, even if the user excessively rotates the ice bank 300 into the ice removal state when attempting to remove it. Reversing the rotation back to the pre-installed removal position will improve fault tolerance.

[0180] In addition, when the ice storage box 300 is converted from the pre-installed state to the ice storage state, even if the user rotates the ice storage box 300 in the wrong direction, the ice storage box 300 can be rotated to the ice removal position, providing a fault tolerance mechanism for the user to avoid the ice storage box 300 from being installed or accidentally falling off due to unskilled operation.

[0181] Reference Figure 9 and Figure 10 The arcuate track groove 240 includes a first arcuate wall 241 and a second arcuate wall 242 that are radially opposed to each other in the arcuate track groove 240. The first arcuate wall 241 is located above the second arcuate wall 242 and defines a first opening 2401 for the mating portion 330 to enter and exit the arcuate track groove 240. The first arcuate wall 241 and the second arcuate wall 242 are radially opposed to each other in the arcuate track groove 240 and are spaced apart from each other.

[0182] The arcuate track groove 240 further includes a first end wall 243 and a second end wall 244, which are respectively connected to the ends of the first arcuate wall 241 and the second arcuate wall 242 in the extension direction. The first arcuate wall 241 and the second arcuate wall 242 extend in the direction in which the arc of the arcuate track groove 240 extends.

[0183] Thus, the first arc wall 241 , the second arc wall 242 , the first end wall 243 and the second end wall 244 enclose an annular arc structure, which is disposed on the mounting side plate 230 of the mounting bracket 200 to form an arc track groove 240 .

[0184] In some embodiments, the mating portion 330 is cylindrical, and the first end wall 243 and the second end wall 244 are arc-shaped walls that fit together with the mating portion 330. This helps to increase the contact area between the mating portion 330 and the first end wall 243 and the second end wall 244, disperses stress, and improves the restrictive effect of the first end wall 243 and the second end wall 244 on the mating portion 330.

[0185] Combine Figure 10 When the ice storage box 300 is in the ice storage state, the matching portion 330 abuts against the first end wall 243. Thus, when the ice storage box 300 is in the ice storage state, the first curved wall 241 and the second curved wall 242 cooperate to limit the matching portion 330 along the height direction of the door body 20 (corresponding to Figure 10 The degree of freedom of the mating portion 330 along the first direction A1 is limited by the first end wall 243.

[0186] Combine Figure 11 and Figure 12 When the ice bank 300 is in the ice removal state, the engaging portion 330 abuts the second end wall 244. Thus, in this state, the first curved wall 241 and the second curved wall 242 cooperate to restrict the freedom of the engaging portion 330 along the height direction of the door body 20. The second end wall 244 also restricts the freedom of the engaging portion 330 along the second direction A2. Furthermore, the freedom of the ice bank 300 along the second tilt direction is restricted, ensuring that the ice bank 300 remains stable in the ice removal state without the user having to manually restrain the ice bank 300, thereby ensuring convenient ice removal. The angle between the second tilt direction and the height direction of the door body 20 is the second tilt angle β.

[0187] The second end wall 244, which serves as a structure for restraining the mating portion 330 when the ice storage bin 300 is in the ice removal state, requires high structural strength. In some embodiments, a first reinforcement structure 245 is provided on the outer side of the second end wall 244, facing away from the first end wall 243, along the extension direction of the arcuate track groove 240. The first reinforcement structure 245 may include multiple ribs to enhance the structural strength of the second end wall 244.

[0188] For example, the first reinforcement structure 245 may include an annular rib and an internal rib. The annular rib is connected to the second end wall 244 to form a closed ring, and the internal rib is arranged on the inner side of the closed ring.

[0189] The first reinforcement structure 245 and the portion of the first curved wall 241 located on the side of the first opening 2401 facing the second end wall 244 form a curved surface 2451. For example, the curved surface 2451 can be an arcuate surface. When the mating portion 330 enters the arcuate track groove 240 through the first opening 2401, the mating portion 330 contacts the curved surface 2451, which can reduce the contact area between the mating portion 330 and the curved surface 2451, thereby reducing friction and allowing the mating portion 330 to pass through the first opening 2401 and enter the arcuate track groove 240 more smoothly.

[0190] The arcuate track groove 240 of the present embodiment is provided with a first arcuate wall 241 and a second arcuate wall 242 to limit the arcuate direction of the arcuate track groove 240. The first end wall 243 and the second end wall 244 are provided at both ends of the first and second arcuate walls 241 and 242 in the direction of extension, respectively, to limit the position of the mating portion 330 along the first and second directions. Together with the first and second arcuate walls 241 and 242, the mating portion 330 is restricted in its freedom of movement in both the ice storage and ice removal states, thereby improving the stability of the ice bank 300 in both the ice storage and ice removal states. In the ice removal state, the ice bank 300 maintains a stable position, facilitating easier ice removal.

[0191] Continue to refer to Figure 10 In some embodiments of the present application, the first arc-shaped wall 241 has a first end face 2411 and a second end face 2412 that are opposite to each other and spaced apart along its extension direction, and a first opening 2401 is formed between the first end face 2411 and the second end face 2412; the first end face 2411 is close to the first end wall 243, and the second end face 2412 is close to the second end wall 244.

[0192] In the embodiment of the present application, the second end surface 2412 has an inner side and an outer side that are opposite each other. The inner side of the second end surface 2412 is connected to the inner surface of the first curved wall 241 via a curved surface, while the outer side of the second end surface 2412 is connected to the outer surface of the first curved wall 241 via a curved surface, forming a smooth end surface structure. This not only avoids stress concentration but also allows the mating portion 330 to enter and exit the first opening 2401 more smoothly. The first end surface 2411 also forms a smooth end surface structure with the inner and outer surfaces of the first curved wall 241.

[0193] Along the extending direction of the first arc-shaped wall 241 (corresponding to Figure 10 In the first direction A1, a first distance is defined between the first end surface 2411 and the first end wall 243, and a second distance is defined between the second end surface 2412 and the second end wall 244. The second distance is smaller than the first distance. Thus, the first opening 2401 is closer to the second end wall 244.

[0194] This arrangement positions the first opening 2401 near the first end wall 243, placing it closer to the ice removal state. This, in turn, places the first opening 2401 higher than the second end wall 244 along the height of the door body 20. Consequently, when the ice bank 300 transitions from the detached state, the mating portion 330 passes through the first opening 2401 and enters the arcuate track groove 240 in a direction inclined relative to the door body 20, achieving a pre-installed state. Furthermore, as the mating portion 330 slides in a first direction along the arcuate track groove 240 from the first opening 2401 to the first end wall 243, it tends to slide downward, facilitating smoother installation of the ice bank 300. The proximity of the first opening 2401 to the second end wall 244 results in a relatively large first inclination angle of the ice bank 300, facilitating assembly and disassembly of the ice bank 300.

[0195] Moreover, the path of the matching portion 330 sliding to the first end wall 243 in the first direction is greater than the path of the matching portion 330 sliding to the second end wall 244 in the second direction, which can prevent incorrect installation.

[0196] In addition, the first opening 2401 is arranged away from the center of the first arc-shaped wall 241, so that the disassembly position of the ice storage box 300 is clear, thereby avoiding the problem that the disassembly position is unclear and affects the convenience of disassembly and assembly.

[0197] Through the above arrangement, when the ice storage box 300 rotates from the ice storage state to the ice removal state, it needs to pass through the first opening 2401, so that the rotation direction of the ice storage box 300 for taking ice in the ice removal state is the same as the rotation direction for disassembling and taking ice, ensuring the consistency of the user's ice removal operation and simplifying the ice removal operation.

[0198] Reference Figure 13 In some embodiments of the present application, the first curved wall 241 is connected to the first inclined wall 246, and the connection between the first inclined wall 246 and the first curved wall 241 is located on the side of the first opening 2401 facing the door body, that is, the connection between the first inclined wall 246 and the first curved wall 241 is located on the side of the first opening 2401 facing the first end wall 243.

[0199] The first inclined wall 246 is inclined relative to the height direction of the door body and is inclined in a direction away from the door body. The first inclined wall 246 is inclined toward the edge of the mounting side plate 230 away from the mounting back plate.

[0200] The surface of the first inclined wall 246 facing the first opening 2401 is connected to and coplanar with the end surface of the first opening 2401 facing the first end wall 243. That is, the surface of the first inclined wall 246 facing the first opening 2401 is connected to and coplanar with the first end surface 2411. This allows the fitting portion 330 to slide smoothly into the arcuate track groove 240 along the first inclined wall 246 during installation of the ice bank 300.

[0201] Continue to refer to Figure 13 One end of the first arc-shaped wall 241 forming the first end surface 2411 is connected to the first inclined wall 246 , and the first inclined wall 246 extends obliquely toward one side of the second end surface 2412 .

[0202] For example, one end of the first inclined wall 246 away from the first arc-shaped wall 241 extends to an edge of the mounting side plate 230 away from the mounting back plate 210. The first inclined wall 246 may be a protruding structure provided on the mounting side plate 230.

[0203] The orthographic projection of the first inclined wall 246 on the horizontal plane of the door covers the first opening 2401. Thus, when the ice bank 300 is installed, the first inclined wall 246 can limit the installation angle of the ice bank 300 and restrict the mating portion 330 from entering the first opening 2401 along the first inclined wall 246. This not only helps to facilitate the installation of the ice bank 300 but also serves as a foolproof measure by preventing the mating portion 330 from being inserted outside the arcuate track groove 240. The horizontal plane of the door can correspond to the XY plane in the figure.

[0204] In the embodiment of the present application, a first inclined wall 246 is connected to one end of the first curved wall 241 forming the first end surface 2411 to restrict the mating portion 330 from entering the arcuate track groove 240 through the first opening 2401. This prevents the mating portion 330 from moving outside the arcuate track groove 240 when the ice bank 300 is pre-installed in an inclined direction relative to the door body 20. Furthermore, the inclined configuration of the first inclined wall 246 guides the mating portion 330 from entering the arcuate track groove 240 through the first opening 2401, thereby improving the ease of assembly and disassembly of the ice bank 300 and, in turn, facilitating the removal of ice from the ice bank 300.

[0205] The wall surface of the first inclined wall 246 facing the first opening 2401 is connected to and coplanar with the first end face 2411, so that the first end face 2411 and the wall surface of the first inclined wall 246 facing the first opening 2401 have the same inclination angle, thereby making the connection between the wall surface of the first inclined wall 246 facing the first opening 2401 and the first end face 2411 smoother, which helps to improve the smoothness of the mating portion 330 entering the arc-shaped trajectory groove 240 along the first inclined wall 246 through the first opening 2401, and avoid the mating portion 330 from getting stuck at the first end face 2411 and affecting the convenience of installation.

[0206] Continue to refer to Figure 13 and Figure 14In some embodiments, the first inclined wall 246 includes a first wall segment 2461 and a second wall segment 2462, wherein the first wall segment 2461 is connected to one end of the first curved wall 241 to form the first end surface 2411. The wall surface of the first wall segment 2461 facing the second end surface 2412 is connected to the first end surface 2411 and is coplanar.

[0207] The first wall section 2461 extends along a first inclined direction, and the second wall section 2462 extends along a second inclined direction. A first angle a1 is formed between the first inclined direction and the height direction of the door body, and a second angle a2 is formed between the second inclined direction and the height direction of the door body. The second angle a2 is greater than the first angle a1.

[0208] Therefore, when the matching portion 330 slides into the first opening 2401 along the first inclined wall 246, the matching portion 330 slides from the second section wall 2462 to the first section wall 2461. Compared with the second section wall 2462, the first section wall 2461 is closer to the height direction of the door body. As a result, as the matching portion 330 slides toward the first opening 2401, the matching portion 330 approaches the height direction of the door body under the action of the first inclined wall 246, so that the downward component of the force between the matching portion 330 and the first inclined wall 246 increases, making it easier for the matching portion 330 to slide into the first opening 2401, thereby making the installation of the ice storage box 300 more labor-saving and smooth.

[0209] The direction of the line between one end of the first end face 2411 formed by the first arc-shaped wall 241 and the rotation center of the rotating shaft portion 340 is the first radial direction, the angle formed between the first inclined direction and the first radial direction has a first angle, and the angle formed between the second inclined direction and the first radial direction has a second angle, and the second angle is greater than the first angle.

[0210] With the above arrangement, the matching portion 330 can smoothly enter the arc-shaped track groove 240 through the first opening 2401 downward along the extending direction of the first inclined wall 246 .

[0211] It should be noted that when there is sufficient space for arranging the two mounting side panels 230, both mounting side panels 230 can be arranged. Figure 13 The first inclined wall 246 is shown. When the arrangement space for installing the side plate 230 is insufficient, the first inclined wall 246 can be provided with only a shorter section, for example Figure 12 The first inclined wall 246 is shown in FIG.

[0212] In some embodiments of the present application, the mounting side plate 230 close to the switch side of the door body 20 is provided with a locking mechanism 400, a mounting switch and other structures to be described later, so that the arrangement space of the first inclined wall 246 is limited, and the structure of the first inclined wall 246 can only include the first section wall 2461, such as Figure 12There is sufficient space on the mounting side panel 230 near the hinge side of the door body 20, and the first inclined wall 246 may include a first section wall 2461 and a second section wall 2462, as shown. Figure 13 shown.

[0213] In the above description, the first inclined wall 246 is composed of two inclined walls with different inclination angles, but this is not restrictive. The first inclined wall 246 can be formed by one inclined wall, such as Figure 12 The first inclined wall 246 may also include three or more sections of inclined walls, and along the direction of sliding into the first opening 2401, the inclined direction of the inclined wall gradually approaches the height direction of the door body.

[0214] Continue to refer to Figure 13 In some embodiments of the present application, a portion of the first arcuate wall 241 protrudes toward the second arcuate wall 242 to form an elastic limiting portion 2413; the elastic limiting portion 2413 is located on the side of the first opening 2401 facing the first end wall 243.

[0215] Combine Figure 10 When the ice storage box 300 is in the ice storage state, the elastic limiting portion 2413 abuts against the matching portion 330 to limit the freedom of the matching portion 330 along the second direction.

[0216] Therefore, the ice storage box 300 in the ice storage state is restricted in its upward and downward freedom along the height direction of the door body 20 under the restrictions of the first curved wall 241, the second curved wall 242, the first section wall 2461 and the elastic limiting portion 2413, and the freedom along the first direction and the second direction is restricted to ensure that the ice storage box 300 is stably and reliably restricted in the ice storage state, thereby ensuring the stability of the ice storage state and avoiding the possibility of the ice storage box 300 loosening due to vibrations such as the opening and closing of the door body 20.

[0217] Furthermore, the elastic stopper 2413 can also provide a prompt when the ice bank 300 is rotated to or from the ice storage state. Specifically, when the engaging portion 330 moves along the arcuate track groove 240 in the first direction, the engaging portion 330 squeezes the elastic protrusion, producing a similar "click" sound, indicating that the ice bank 300 has rotated to the ice storage state. This prevents the user from rotating the ice bank 300 inappropriately due to improper rotation, which could affect the reliability of ice storage.

[0218] In some embodiments of the present application, the first curved wall 241 is divided into two sections by the first opening 2401. The section where the first curved wall 241 connects to the first end wall 243 has a thinner wall thickness, which facilitates elastic deformation of the elastic stopper 2413 and, in turn, helps the mating portion 330 pass through the elastic stopper 2413. The section where the first curved wall 241 connects to the second end wall 244 has a thicker wall thickness, which helps improve the structural strength of the second end wall 244, thereby ensuring the stability of the ice storage box 300 in the ice removal state.

[0219] Continue to refer to Figure 10 A portion of the first curved wall 241 is recessed away from the second curved wall 242 to form a recessed portion 2414. The recessed portion 2414 is located on the side of the elastic limiting portion 2413 facing the first opening 2401. This configuration provides a buffer for deformation of the elastic limiting portion 2413, making it easier for the elastic limiting portion 2413 to deform, thereby making it easier for the mating portion 330 to move into contact with the first end wall 243.

[0220] like Figure 10 As shown, in some embodiments of the present application, the arcuate trajectory groove 240 further includes a protective wall 247. One end of the protective wall 247 is connected to the outer side of the first end wall 243, and the other end of the protective wall 247 extends to the first inclined wall 246. The protective wall 247 is located outside the first arcuate wall 241 and is spaced apart. The protective wall 247 is located on the side of the first opening 2401 facing the first end wall 243. It can be understood that the protective wall 247 is located outside the elastic limiting portion 2413 and the recessed portion 2414, and serves to protect the elastic limiting portion 2413 and the recessed portion 2414.

[0221] Combine Figure 13 A hollow portion 231 is provided on the mounting side plate 230 , and the hollow portion 231 allows the first arc-shaped wall 241 provided with the elastic limiting portion 2413 and the recessed portion 2414 to be partially suspended, which helps to improve the elastic deformation ability of the elastic limiting portion 2413 .

[0222] like Figure 12 As shown, in some embodiments of the present application, an elastic damping member 248 is provided on the groove wall of the arc-shaped trajectory groove 240. For example, the elastic damping member 248 is provided on the second arc-shaped wall 242, and along the second direction A2, the elastic damping member 248 is located on the side of the first opening 2401 facing the second end wall 244.

[0223] Along the second direction A2, the elastic damping member 248 is located on the side of the first opening 2401 facing the second end wall 244. Thus, the elastic damping member 248 is located between the second end surface 2412 and the second end wall 244. In this manner, the elastic damping member 248 limits the freedom of the mating portion 330 along the first direction while not affecting the mating portion 330's entry and exit into the first opening 2401.

[0224] Among them, the elastic damping member 248 can make the elastic silicone member, rubber member, etc. not only play a damping role, but also the flexible contact between the matching part 330 and the elastic damping member 248, thereby helping to reduce the jamming force between the matching part 330 and the elastic damping member 248, and further reducing the influence of the jamming force on the outward sliding of the ice cubes.

[0225] Combine Figure 13 A bayonet 2421 is provided on the second arc-shaped wall 242 , and the elastic damping member 248 is engaged with the bayonet 2421 , which has a simple connection method and is easy to replace.

[0226] In other embodiments, combined Figure 14 The elastic damping member 248 can be a convex structure provided on the second arc-shaped wall 242. In this way, the elastic damping member 248 and the arc-shaped track groove 240 are integrally formed, and the structure is simple.

[0227] When the ice bank 300 is in the ice removal state, the elastic damping member 248 elastically abuts against the mating portion 330 to limit the freedom of the ice bank 300 along the first direction. Thus, in the ice removal state, the elastic damping member 248 restricts the freedom of the ice bank 300 along the first direction, preventing the ice bank 300 from rotating freely in the first direction when ice is removed. This helps improve the stability of the ice bank 300 in the ice removal state, eliminates the need for the user to manually secure the ice bank 300, and further facilitates ice removal.

[0228] When the ice bank 300 is switched from the ice storage state to the pre-installed state, if the user rotates excessively, the fitting portion 330 contacts the elastic damping member 248, thereby increasing the rotational resistance of the ice bank 300, thereby prompting the user to rotate excessively.

[0229] Furthermore, because the elastic damping member 248 is located near the first opening 2401, if the user rotates the ice bank 300 excessively during the transition from the ice storage state to the pre-installed state, causing the ice bank 300 to enter the ice removal state, the engaging portion 330 overcomes the resistance of the elastic damping member 248, thereby also serving as a warning, indicating that the ice bank 300 has been rotated excessively and entered the ice removal state. At this point, the user can rotate the ice bank 300 in the opposite direction to overcome the resistance of the elastic damping member 248, allowing the ice bank 300 to move from the ice removal state to the pre-installed state, facilitating removal of the engaging portion 330 through the first opening 2401. Therefore, the elastic damping member 248 also serves as a warning.

[0230] In some embodiments of the present application, a resistance portion may be provided on the wall of the arcuate track groove 240. The resistance portion is radially opposite the first opening 2401 and is provided on the second arcuate wall 242 opposite the first opening 2401. The resistance portion may be a damping layer provided on the second arcuate wall 242. Providing the resistance portion on the second arcuate wall 242 increases the resistance of the mating portion 330 as it moves along the arcuate track groove 240 past the first opening 2401, thereby indicating the assembly and disassembly position of the ice storage bin 300 and facilitating the removal and removal of ice from the ice storage bin 300.

[0231] Continue to refer to Figure 13 In some embodiments of the present application, the mounting slot 250 is constructed to form an upward second opening 2501 so that the shaft portion 340 can be installed into the mounting slot 250 through the second opening 2501 , or removed from the mounting slot 250 through the second opening 2501 .

[0232] The wall of the mounting groove 250 includes a third curved wall 251, which is configured to form a rotation hole portion 2511 having an opening. The rotation hole portion 2511 rotatably engages with the rotation shaft portion 340, forming the rotation center for the engagement portion 330 to move along the arcuate trajectory groove 240. The axial direction of the rotation hole portion 2511 is parallel to the width direction of the door body 20.

[0233] The third arc-shaped wall 251 may be a protruding structure provided on the mounting side plate 230 , which not only forms the rotation hole portion 2511 , but also plays a reinforcing role, thereby improving the structural strength of the mounting side plate 230 .

[0234] The groove wall of the installation groove 250 may further include an outer wall 252 , which is connected to one end of the third curved wall 251 in the extending direction, and is located on a side of the third curved wall 251 away from the door body 20 .

[0235] The groove wall of the installation groove 250 may further include an inner wall 253 , which is connected to the other end of the third arc-shaped wall 251 in the extending direction; the inner wall 253 is closer to the door body 20 than the outer wall 252 .

[0236] Both the outer side wall 252 and the inner side wall 253 can be protruding walls provided on the mounting side plate 230 , which not only form the groove wall of the mounting groove 250 but also play a reinforcing role.

[0237] The outer wall 252 and the inner wall 253 are spaced apart at one end away from the third curved wall 251 to form a second opening 2501. The second opening 2501 is located above the third curved wall 251. Thus, the third curved wall 251, the outer wall 252 and the inner wall 253 enclose a mounting slot 250 with an upper opening.

[0238] In the embodiment of the present application, the wall of the mounting slot 250 is provided with a third curved wall 251 to form a rotation hole 2511. The rotation hole 2511 rotatably engages with the rotation shaft 340, allowing the ice bank 300 to rotate relative to the door 20. The inner sidewall 253 and the outer sidewall 252 are connected on either side of the third curved wall 251, defining a second opening 2501 above the third curved wall 251. This provides a passage and restriction for the rotation shaft 340 to enter and exit the rotation hole 2511 through the second opening 2501.

[0239] Moreover, the second opening 2501 is located above the third arc-shaped wall 251. Figure 7 When the matching portion 330 enters the arc-shaped trajectory groove 240 through the first opening 2401 , the rotating shaft portion 340 enters the rotating hole portion 2511 through the second opening 2501 , so that the rotating shaft portion 340 can rotate relative to the rotating hole portion 2511 , thereby allowing the matching portion 330 to move along the arc-shaped trajectory groove 240 .

[0240] In the embodiment of the present application, the arc-shaped trajectory groove 240 is an arc-shaped groove with the rotation center of the rotating shaft portion 340 as the center of the circle. The rotation hole portion 2511 is provided at a position close to the bottom of the mounting side plate 230 and away from the mounting back plate 210. The arc-shaped trajectory grooves 240 of the two mounting side plates 230 are of the same size, which is convenient for processing and installation. One of the mounting side plates 230 is provided with a locking mechanism 400, a mounting switch and other structures, which limits the radius of the arc-shaped trajectory groove 240. Within the space of the mounting side plate 230, the radius of the arc-shaped trajectory groove 240 can be as large as possible, so that the distance between the matching portion 330 and the rotating shaft portion 340 is as large as possible, which helps to improve the reliability and stability of the connection between the ice storage box 300 and the mounting bracket 200.

[0241] Continue to refer to Figure 13 and Figure 14 In some embodiments, the groove wall of the mounting groove 250 is located on the side of the second opening 2501 facing the door body and is connected to a second inclined wall 254, and the second inclined wall 254 extends to and is connected to the outer side of the end of the arc-shaped trajectory groove 240 away from the door body.

[0242] One end of the inner side wall 253 away from the third arc-shaped wall 251 is connected to the second inclined wall 254 , and the second inclined wall 254 extends to and is connected to the outer side of the groove wall of the arc-shaped track groove 240 away from the door body.

[0243] The second inclined wall 254 extends to the side of the first reinforcement structure 245 away from the second end wall 244. Since the end of the arc-shaped trajectory groove 240 away from the mounting side plate 230 is opposite to the second opening 2501 in the height direction, the orthographic projection of the groove wall of the arc-shaped trajectory groove 240 on the horizontal plane of the door body 20 covers the inner side wall 253. Therefore, the second inclined wall 254 is inclined relative to the height direction of the door body 20.

[0244] In this embodiment of the present application, a second inclined wall 254 is provided between the inner sidewall 253 of the mounting groove 250 and the wall of the arcuate track groove 240 near the edge of the door body 20. This serves as a foolproof feature, preventing the rotating shaft portion 340 from becoming stuck in the gap between the arcuate track groove 240 and the mounting groove 250 during installation. The second inclined wall 254 restricts the rotating shaft portion 340, allowing it to smoothly enter the mounting groove 250. This, in turn, facilitates installation of the ice bank 300 and facilitates removal of the ice bank 300 for ice removal.

[0245] Moreover, the second inclined wall 254 is a protruding wall provided on the mounting side plate 230 , which helps to improve the structural strength of the mounting side plate 230 .

[0246] In some embodiments of the present application, the surface of the second inclined wall 254 facing the second opening 2501 is tangentially connected to the outer side surface of the arcuate track groove 240 at the end facing away from the door body. This tangential connection between the surface of the second inclined wall 254 facing the second opening 2501 and the curved surface 2451 makes the surface of the second inclined wall 254 facing the second opening 2501 smoother, allowing the hinge portion 340 to slide downward more smoothly under the restraint of the second inclined wall 254, thereby improving the convenience of installing the ice storage bin 300.

[0247] In some embodiments, the rotating shaft portion 340 can be cylindrical and rotatably engaged with the rotating hole portion 2511. The center of the cylindrical rotating shaft portion 340 is the rotation center. In this way, the rotating shaft portion 340 has a simple structure and is easy to process.

[0248] In other embodiments, combined Figures 9 to 12 The rotating shaft portion 340 may include a shaft body 341 that is rotatably engaged with the rotating hole portion 2511. When the ice storage box 300 is switched between the pre-installed state, the ice storage state, and the ice removal state, the engaging portion 330 moves in an arc along the arc-shaped track groove 240 around the center of the shaft body 341.

[0249] The rotating shaft 340 may further include a limiting arm 342 connected to the top of the shaft body 341. The limiting arm 342 cooperates with the outer wall 252 to restrict the ice removal state of the ice storage bin 300. The limiting wall cooperates with the inner wall 253 to restrict the ice storage state of the ice storage bin 300.

[0250] The side of the limiting arm 342 facing away from the door body 20 forms a first abutting surface 3421 that abuts against the outer wall 252 when the ice storage box 300 is in the ice removal state. The side of the limiting arm 342 facing the outer wall 252 forms a first abutting surface 3421.

[0251] Among them, a first limiting surface 2521 is provided on the side of the outer wall 252 facing the inner wall 253. The first limiting surface 2521 abuts against the first abutting surface 3421 when the ice storage box 300 is in the ice taking state, thereby limiting the inclination angle of the ice storage box 300 relative to the door body 20 in the ice taking state.

[0252] When the first abutting surface 3421 abuts against the first limiting surface 2521 , a second inclined angle β is formed between the ice storage box 300 and the door body 20 .

[0253] The hinge portion 340 of the present embodiment is provided with a shaft 341 that rotatably engages with the rotation hole 2511, allowing the ice bank 300 to rotate relative to the door 20. The hinge portion 340 is provided with a limiting arm 342 to restrict the ice bank 300 between the ice removal and ice storage states. The limiting arm 342 forms a first abutting surface 3421 that, when the ice bank 300 is in the ice removal state, engages the outer wall 252. This not only limits the tilt angle of the ice bank 300 in the ice removal state, but also disperses the applied force through the surface contact between the limiting arm 342 and the outer wall 252, preventing concentrated force on the outer wall 252 and potentially damaging it, thereby improving the service life of the outer wall 252. Furthermore, this surface contact ensures that the outer wall 252 more stably and reliably limits the position of the ice bank 300, preventing movement of the ice bank 300 in the ice removal state, thereby enhancing the convenience of ice removal.

[0254] In some embodiments of the present application, the limiting arm 342 and the outer wall 252 are matched with each other in a concave-convex manner to limit the freedom of the rotating shaft portion 340 to move outward along the first limiting surface 2521, thereby ensuring the stable position of the ice storage box 300 in the ice removal state.

[0255] Continue to refer to Figure 10 、 Figure 12 as well as Figure 13 The first limiting groove 3422 is formed on the side of the limiting arm 342 away from the door body 20 . The first limiting groove 3422 is located at the end of the first abutting surface 3421 away from the shaft body 341 . The first limiting groove 3422 opens toward the outer side wall 252 .

[0256] The outer wall 252 is provided with a first protruding portion 2522 . The first protruding portion 2522 is located on a side of the first limiting surface 2521 away from the third arc-shaped wall 251 .

[0257] When the ice storage box 300 is in the ice taking state, the first protrusion 2522 is engaged with the first limiting groove 3422 in a concave-convex manner.

[0258] The first protrusion 2522 includes a first inclined surface and a second inclined surface. The first inclined surface is connected to the first limiting surface 2521 and is inclined toward the inside of the second opening 2501. The angle formed between the first inclined surface and the first limiting surface 2521 is an obtuse angle. The second inclined surface is connected to the first inclined surface and is inclined away from the second opening 2501. The second inclined surface can be perpendicular to the first inclined surface. The first and second inclined surfaces are in surface contact with the first limiting groove 3422 to limit the freedom of the rotating shaft portion 340 to move outward along the first limiting surface 2521, ensuring that the rotating shaft portion 340 is stably mounted in the mounting groove 250 when the ice is removed, thereby ensuring the stability of the ice storage box 300 when the ice is removed.

[0259] In addition, during the installation of the ice storage box 300 , when the rotating shaft portion 340 contacts the second inclined surface, the second inclined surface can also play a guiding role, guiding the rotating shaft portion 340 to slide toward the second opening 2501 and then enter the installation groove 250 .

[0260] The end of the second inclined surface facing away from the first inclined surface can be connected to a horizontal surface, and the end of the horizontal surface facing away from the second inclined surface can extend to the edge of the mounting side plate 230. The horizontal surface can provide a certain amount of support for the rotating shaft portion 340, making it easier for the rotating shaft portion 340 to slide toward the second opening 2501 through contact with the horizontal surface and the second inclined surface.

[0261] The limiting arm 342 of the embodiment of the present application limits the freedom of movement of the ice storage box 300 along the first abutment surface 3421 in the ice removal state by providing a first limiting groove 3422 that cooperates with the first protrusion 2522 provided on the outer wall 252, thereby limiting the rotation shaft portion 340 in the installation groove 250, thereby ensuring the stability of the ice storage box 300 in the ice removal state.

[0262] In contrast to the protrusion structure provided on the limiting arm 342 and the groove structure provided on the outer wall 252, the present embodiment of the present invention provides a first limiting groove 3422 on the limiting arm 342 and a first protrusion 2522 on the outer wall 252, achieving a concave-convex fit. The first protrusion on the outer wall 252 helps to improve the structural strength of the outer wall 252, thereby ensuring stable positioning of the ice storage bin 300 when ice is removed. Furthermore, the first limiting groove 3422 on the limiting arm 342 does not interfere with the installation of the rotating shaft 340 in the mounting groove 250, facilitating smoother installation of the rotating shaft 340 in the mounting groove 250.

[0263] Continue to refer to Figure 13A first limiting surface 2521 is formed on the outer wall 252, which abuts against the first abutting surface 3421 of the limiting arm 342, thereby limiting the position of the ice storage box 300 in the ice removal state. Therefore, the structural strength of the outer wall 252 is crucial. In some embodiments, a second reinforcing structure 2523 is provided on the outer side of the outer wall 252 away from the inner wall 253 to improve the structural strength of the outer wall 252. The second reinforcing structure 2523 may include an open ring-shaped rib, which is connected to the outer wall 252 to form a closed ring. The closed ring is provided with straight ribs, which makes the structure more stable.

[0264] In some implementations of the present application, the side of the limiting arm 342 facing away from the first abutting surface 3421 forms a second abutting surface 3423; the side of the limiting arm 342 facing the inner wall 253 forms a second abutting surface 3423, which is opposite to the first abutting surface 3421 and has a gap.

[0265] The second abutting surface 3423 abuts against the inner side wall 253 when the ice storage box 300 is in the ice storing state.

[0266] The inner sidewall 253 forms a second limiting surface 2531 on one side thereof facing the outer sidewall 252. The second limiting surface 2531 is parallel to the XZ plane. When the ice bank 300 is in the ice storage state, the second limiting surface 2531 abuts against the second abutting surface 3423 to limit the position of the ice bank 300 toward the door 20.

[0267] In this embodiment, the limiting arm 342 is provided with a second abutting surface 3423 that abuts the inner sidewall 253 to limit the position of the ice storage bin 300 when storing ice. Furthermore, the surface contact between the limiting arm 342 and the inner sidewall 253 facilitates stress dispersion, preventing stress concentration that could damage the inner sidewall 253 or the shaft 340.

[0268] In some embodiments of the present application, the limiting arm 342 and the inner side wall 253 are matched with each other in a concave-convex manner to limit the upward freedom of the rotating shaft portion 340 along the height direction of the door body 20, thereby ensuring the stable position of the ice storage box 300 in the ice storage state.

[0269] like Figure 10 and Figure 12 As shown, a second protrusion 3424 is formed on a side of the limiting arm 342 away from the first abutting surface 3421 . The second protrusion 3424 is located at an end of the second abutting surface 3423 away from the shaft body 341 .

[0270] A second limiting groove 2532 is formed on the inner sidewall 253 . The second limiting groove 2532 is located at an end of the second limiting surface 2531 away from the third arc-shaped wall 251 .

[0271] When the ice storage box 300 is in the ice storage state, the second limiting groove 2532 and the second protrusion 3424 are engaged with each other in a concave-convex manner to limit the upward freedom of the ice storage box 300 along the height direction of the door body 20 .

[0272] Illustratively, the contact surface between the second limiting groove 2532 and the second protrusion 3424 is an arc-shaped surface, which helps to disperse stress and avoid stress concentration.

[0273] In some embodiments, combined Figure 13 The inner wall 253 protrudes toward the outer wall 252 to form a third protrusion 2533. The third protrusion 2533 is used to define the second limiting groove 2532 and improve structural strength. The third protrusion 2533 is hollow, which not only prevents shrinkage during molding due to excessive thickness, but also ensures structural strength.

[0274] The third protrusion 2533 forms an inclined surface 2534 on one side facing the second inclined wall 254. The angle formed between the inclined surface 2534 and the surface of the second inclined wall 254 facing the second opening 2501 is an obtuse angle, causing the inclined surface 2534 to tilt toward the second opening 2501. With this arrangement, when the rotation shaft 340 slides toward the second opening 2501 under the restraint of the second inclined wall 254, the rotation shaft 340 enters the second opening 2501 under the restraint of the inclined surface 2534, making the rotation shaft 340 slide smoothly along the second inclined wall 254.

[0275] In the embodiment of the present application, the cooperation between the limiting arm 342 and the inner side wall 253, through the second protrusion 3424 and the second limiting groove 2532, limits the upward freedom of the ice storage box 300 along the height direction of the door body 20, and stably restricts the rotating shaft portion 340 in the installation groove 250, thereby preventing the ice storage box 300 from rotating freely in the ice storage state.

[0276] Continue to refer to Figure 13 In some embodiments of the present application, the second limiting surface 2531 is a plane, and the bottom end of the second limiting surface 2531 is connected to the inner arc surface of the third arc-shaped wall 251. The second limiting surface 2531 and the inner arc surface are not tangentially connected. In this way, the distance between the second limiting surface 2531 and the center of the rotating hole portion 2511 is smaller than the radius of the rotating hole portion 2511. Figure 10 The inner wall 253 can also limit the freedom of the shaft body 341 to move upward.

[0277] Combine Figure 3 In some embodiments of the present application, the refrigerator further includes a locking mechanism 400 , which is located on one side of the ice storage box 300 along the width direction of the door body 20 and away from the hinged side of the door body 20 .

[0278] The locking mechanism 400 is mounted on the mounting side plate 230 of the mounting bracket 200. In order to improve the compactness of the structure, a mounting groove 232 is provided on the mounting side plate 230 to mount and accommodate the locking mechanism 400.

[0279] The locking mechanism 400 has a locking position and an unlocking position, and is configured to rotate relative to the door body 20 between the locking position and the unlocking position. Figure 5 As shown, the locking mechanism 400 is in the locked position; Figure 4 and Figure 6 As shown, the locking mechanism 400 is in the unlocked position.

[0280] When the locking mechanism 400 rotates to the locking position, the locking mechanism 400 abuts against the top of the ice storage box 300 to limit the ice storage box 300 to the ice storage state. Figure 6 A locking wall 350 is provided at the top of the side wall of the ice storage box 300, and the locking mechanism 400 abuts against the locking wall 350, thereby limiting the ice storage box 300 to the ice storage state.

[0281] When the locking mechanism 400 rotates to the unlocking position, the locking mechanism 400 is separated from the ice bank 300 , so that the ice bank 300 can rotate relative to the door body 20 .

[0282] The refrigerator of the present embodiment is provided with a locking mechanism 400 to unlock the ice bank 300, allowing the ice bank 300 to rotate relative to the door 20 for ice removal. The locking mechanism 400 also locks the ice bank 300, ensuring that the ice bank 300 remains in a stable ice storage state. Furthermore, the locking mechanism 400 is located on the side of the ice bank 300 that is hinged away from the door 20, making operation more convenient.

[0283] Reference Figure 15 In some embodiments of the present application, the locking mechanism 400 may include a locking member 410 , which is mounted on the mounting side plate 230 to achieve locking and unlocking of the ice storage box 300 .

[0284] The locking mechanism 400 may include a retaining spring 420 , which is respectively connected to the locking member 410 and the mounting side plate 230 to mount the locking member 410 on the mounting side plate 230 , and the locking member 410 can also rotate relative to the mounting side plate 230 .

[0285] The locking mechanism 400 may further include a cover plate 430, which is fixed to the inner side of the mounting side plate 230 to shield the locking member 410 and the retaining spring 420. For example, the cover plate 430 may be snap-fitted to the mounting side plate 230, providing a simple and stable connection.

[0286] The locking member 410 may include a plate body 411, which may be in the shape of a disk. An operating portion 412 is provided on one side of the plate body 411, and a user may rotate the locking member 410 between a locked position and an unlocked position through the operating portion 412.

[0287] The locking member 410 may further include a rotation shaft 413 . The rotation shaft 413 is located on a side of the plate body 411 away from the operating portion 412 .

[0288] The locking member 410 may further include a locking shaft 414, which is disposed on a side of the plate body 411 away from the operating portion 412. The rotation shaft 413 may be disposed at the center of the plate body 411, and the locking shaft 414 may be disposed at an edge of the plate body 411.

[0289] Part of the locking wall 350 can be configured as an arcuate surface to increase the contact area with the locking shaft 414, thereby improving locking stability. A reinforcing wall can be provided on the side of the locking wall 350 away from the arcuate surface to improve the structural strength of the locking wall 350.

[0290] Combine Figure 16 and Figure 17 The mounting side plate 230 is provided with a first shaft hole 233, through which the rotation shaft 413 passes. A retaining spring 420 is connected to the position where the rotation shaft 413 passes through the first shaft hole 233, and the retaining spring 420 abuts against the inner side surface of the mounting side plate 230. The plate body 411 of the locking member 410 abuts against the outer side surface of the mounting side plate 230, thereby mounting the locking member 410 on the mounting side plate 230 and allowing the locking member 410 to rotate about the rotation shaft 413.

[0291] The mounting side plate 230 is provided with a first arcuate hole 234, through which the locking shaft 414 passes, for contact with the locking wall 350. The locking member 410 is centered about the rotation axis 413, and the locking shaft 414 moves along the first arcuate hole 234, thereby moving the locking mechanism 400 between a locked position and an unlocked position.

[0292] The cover plate 430 may be provided with a second shaft hole 431 , which is coaxial with the first shaft hole 233 . Thus, the rotating shaft 413 passes through the first shaft hole 233 and the second shaft hole 431 .

[0293] The cover plate 430 may be provided with a second arc-shaped hole 432 that is opposite to the first arc-shaped hole 234 along the width direction of the door body 20. The locking shaft 414 passes through the first and second arc-shaped holes 234, 432 to abut against the locking wall 350.

[0294] Therefore, by providing the cover plate 430 and providing the second shaft hole 431 and the second arc hole 432 on the cover plate 430 , the matching length of the rotating shaft 413 and the locking shaft 414 is extended, which helps to improve the installation stability of the locking member 410 .

[0295] Combine Figure 15 The mounting side plate 230 may also be provided with a first latching protrusion 235, and the plate body 411 of the locking member 410 may be provided with a second latching protrusion 415. The second latching protrusion 415 is located on the side of the plate body 411 where the locking shaft 414 is provided. When the locking member 410 is rotated to the locked position, the second latching protrusion 415 passes over the first latching protrusion 235, creating a sense of friction, thereby notifying the user that the ice bank 300 is locked in place, thereby improving operational convenience.

[0296] Reference Figure 18 In some embodiments of the present application, the locking mechanism 400 rotates around the first center, and the shaft portion 340 rotates around the second center; the angle γ formed between the line connecting the first center and the second center and the height direction of the door body 20 is greater than 4° and less than 15°.

[0297] The first center of the circle may be the center of the first rotating hole, and the second center of the circle may be the center of the rotating shaft portion 340 .

[0298] In the embodiment of the present application, the line connecting the first and second center points is tilted relative to the height direction of the door body 20, so that the distance between the rotation center of the locking mechanism 400 and the rotation center of the ice bank 300 is as far as possible, forming a longer moment arm. This increases the torque applied to the locking mechanism 400. According to the principle of counter-torque balance, the smaller the counter-torque applied by the locking mechanism 400 to the ice bank 300, the smaller the resistance applied by the locking mechanism 400 to the rotation of the ice bank 300, thereby ensuring the stability of the locking mechanism 400 in restricting the rotation of the ice bank 300.

[0299] Moreover, by setting the angle between the line connecting the first center of the circle and the second center of the circle and the height direction of the door body 20, the distance between the rotation center of the locking mechanism 400 and the rotation center of the ice storage box 300 can be made as far as possible, and the arrangement position of the locking mechanism 400 can also be made flexible.

[0300] In some embodiments of the present application, Figure 19 The side panel 230 may further include a sensor switch 236 for sensing whether the ice storage box 300 is in an ice storage state. The sensor switch 236 may be disposed above the arc-shaped track groove 240 .

[0301] Combine Figure 4The ice storage box 300 is provided with a trigger portion 360 on the side wall along the width direction of the door body 20. When the ice storage box 300 is in the ice storage state, the trigger portion 360 triggers the induction switch 236 to send an induction signal to indicate that the ice storage box 300 is in the ice storage state.

[0302] The controller of the refrigerator can control the ice maker 100 to start making ice according to the sensing signal of the sensing switch 236 to ensure that the ice cubes made by the ice maker 100 can fall into the ice storage box 300.

[0303] The sensing switch 236 may be a micro switch. When the ice storage box 300 is installed in the ice storage state, the triggering part 360 triggers the micro switch to close and send out a sensing signal.

[0304] The induction switch 236 may be a magnetic switch, and the trigger portion 360 may be a magnetic member, such as a magnet. When the ice storage box 300 is installed in the ice storage state, the trigger portion 360 and the magnetic switch are magnetically closed and an induction signal is emitted.

[0305] When the ice bank 300 leaves the ice storage state, the distance between the trigger portion 360 and the sensor switch 236 increases, so that the sensor switch 236 is open, indicating that the ice bank 300 is not in the ice storage state.

[0306] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
