Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] At present, refrigerators may be equipped with an ice maker to provide users with ice cubes for daily use. The ice maker is generally arranged in an ice making chamber isolated from a refrigerator or a freezer, and may use a closed ice making grid or an open ice making grid to make ice cubes.

[0003] In the existing ice making machines using folding molds to make ice cubes, the two molds are mostly arranged vertically. After the two molds are closed, the ice-making water is injected between the two molds. In the closed state of the existing ice making machine, the relative force between the two molds is small, resulting in insufficient sealing between the two molds, so that there is a gap at the joint of the molds, which in turn causes the mold to leak when closed. Or, when the weight of the ice-making water is large, the ice-making water seeps out from the intersection of the two molds, causing the mold to leak when closed. The above situations will cause a large amount of water to be injected into the ice storage bucket below, causing the ice cubes in the ice storage bucket to stick together and affect the user's use of ice cubes.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0062] The refrigerator 100 provided in the embodiment of the utility model can have various implementation forms. Figures 1 to 11 This is a specific implementation of the refrigerator 100 of the utility model. In this embodiment, the refrigerator 100 includes a cabinet 1A, a refrigeration system (not shown), an air supply system (not shown), and a door body (not shown).

[0063] The directions described in the text are based on the direction in which the user faces the refrigerator 100, wherein the left and right sides are distinguished by the direction in which the user faces the refrigerator 100, the side facing the user when the refrigerator 100 is in use is defined as the front side, and the side opposite thereto is defined as the rear side, and the upper and lower sides of the refrigerator 100 when generally working normally are defined to distinguish the up and down.

[0064] like Figure 1 As shown, the box 1A is used to form the overall appearance of the refrigerator 100. The box 1A is roughly in the shape of a rectangular parallelepiped frame. The top of the box 1A and the bottom of the box 1A are opposite ends. From the top of the box 1A to the bottom of the box 1A is the height direction of the box 1A. The left side of the box 1A and the right side of the box 1A are opposite sides. From the left side of the box 1A to the right side of the box 1A is the width direction of the box 1A. The front side of the box 1A and the rear side of the box 1A are opposite sides. From the front side of the box 1A to the rear side of the box 1A is the thickness direction of the box 1A. The box 1A includes an inner liner and a box shell. The inner liner is arranged in the box shell, and an installation space is formed between the two, which is used to install other component structures of the refrigerator 100 and form a foam insulation layer. A refrigeration chamber 10A for placing goods is formed inside the inner tank. The refrigeration chamber 10A is provided with a chamber opening, and the chamber opening direction is arranged toward the front side of the box body 1A. The refrigeration chamber 10A can be a refrigerated temperature environment, a frozen temperature environment, or a normal temperature environment. A door body is provided at the chamber opening, and the door body is arranged in a straight plate shape at the front side of the box body 1A. The door body can be connected to the box body 1A in an openable and closable manner to open or close the refrigeration chamber 10A.

[0065] The refrigeration system is used to provide cold air to the refrigeration chamber 10A; the refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a filter drier, a return air pipe, a throttling device, and a refrigerant. Each component is distributed at different positions of the cabinet 1A according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process, and an evaporation process. The compression process is: after the power cord of the refrigerator 100 is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a filter drier to remove moisture and impurities and then flows into the throttling device, and the throttling and pressure reduction are performed through the throttling device, and the refrigerant becomes a wet vapor at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat to gasify, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the change of the state of the refrigerant, and the heat in the refrigerator 100 is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator 100.

[0066] The air supply system is installed in the box 1A, and is used to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box 1A. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box 1A is also defined to form an air duct cavity, which is connected to the air supply duct and the refrigeration chamber 10A respectively, so that the air supply duct is connected to the refrigeration chamber 10A through the air duct cavity; it should be noted that the inner liner is provided with an air outlet, and the air outlet is used to connect the air duct cavity and the refrigeration chamber 10A. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber 10A to cool the refrigeration chamber 10A. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall on the side opposite to the opening of the inner tank and the refrigeration chamber 10A or on the side adjacent to the opening of the inner tank and the refrigeration chamber 10A; it should also be noted that the refrigeration system and the air supply system belong to common knowledge in the field and will not be described here.

[0067] In the refrigerator 100, reference Figures 1 to 11The refrigeration chamber 10A is provided with an ice-making assembly 2A for preparing ice cubes. Generally speaking, the ice-making process of the ice-making assembly 2A is as follows: water is injected into the mold for holding liquid inside the ice-making assembly 2A, and cold energy is provided to the ice-making chamber so that the water in the mold freezes into ice cubes, and then the ice cubes are demolded from the mold and fall into the ice storage box for users to take.

[0068] Specifically, the ice-making assembly 2A provided in this embodiment includes an assembly housing 1, the assembly housing 1 defines an assembly space 1a for mold installation and movement, and in the width direction of the assembly housing 1, that is, Figure 3 In the first direction shown, three positioning posts 2 are respectively arranged on both sides of the component housing 1 to control the movement stroke of the mold located inside the component space 1a.

[0069] Two molds are provided in the component space 1a. In this embodiment, the two molds are respectively a first mold 3 and a second mold 4, wherein the first mold 3 can be opened and closed with the second mold 4, so that when the first mold 3 and the second mold 4 are closed, a mold cavity for preparing ice cubes is formed. It can be understood that the shape of the mold cavity can be determined according to the functional requirements of the ice-making component 2A, and can be square, spherical or other shapes.

[0070] As an example of this embodiment, the second direction is from the top of the mold cavity to the bottom of the mold cavity. The first mold 3 and the second mold 4 of this embodiment are molds arranged vertically along the second direction, and both are hemispherical molds. When the first mold 3 and the second mold 4 are closed, the surface where the first mold 3 and the second mold 4 intersect, that is, the closing surface, is a plane arranged vertically along the second direction, and the mold cavity formed by the two is a spherical mold cavity, so that when the first mold 3 and the second mold 4 are separated, the spherical ice cubes can be removed from the mold cavity for users to take.

[0071] refer to Figure 3 The ice-making assembly 2A further includes a driving assembly 5, which is configured to at least drive the first mold 3 or the second mold 4 to open and close according to functional parameters of the first mold 3 or the second mold 4, so that the first mold 3 can perform an opening and closing action with the second mold 4.

[0072] As an example of this embodiment, the direction in which the first mold 3 and the second mold 4 perform the opening and closing action is Figure 3 The driving assembly 5 comprises a driving block 5a and an elastic member 5b, wherein:

[0073] The driving block 5a is configured to drive the first mold 3 or the second mold 4 to open and close along the first direction;

[0074] One end of the elastic member 5b is connected to the driving block 5a, and the other end of the elastic member 5b is connected to the mold driven by the driving assembly 5, and the driving block 5a is configured to have a first position, a second position, and a third position, and the driving block 5a can move among the first position, the second position, and the third position, wherein,

[0075] The first position enables the first mold 3 and the second mold 4 to open; the second position enables the first mold 3 and the second mold 4 to close; the third position enables the driving block 5a located at the second position to move toward the other mold, close to the other mold, and enables the elastic member 5b to deform so that the elastic member 5b applies a force to the mold connected to the driving block 5a to move toward the other mold.

[0076] It can be understood that, according to the functional settings of the first mold 3 and the second mold 4, one of the first mold 3 or the second mold 4 can be a movable mold, and the other can be a static mold. In this case, the driving component 5 is connected to the movable mold, driving the movable mold to move relative to the static mold, thereby causing the first mold 3 and the second mold 4 to move relative to each other and perform an opening and closing action. Alternatively, the first mold 3 and the second mold 4 can both be movable molds. In this case, there are multiple driving components 5, which are respectively connected to the first mold 3 and the second mold 4, driving the first mold 3 and the second mold 4 to move toward each other, so that the first mold 3 and the second mold 4 open and close.

[0077] It can be understood that one end of the elastic member 5b is connected to the driving block 5a, and the other end of the elastic member 5b is connected to the mold driven by the driving assembly 5. In this way, when the driving assembly 5 is connected to the first mold 3, the corresponding elastic member 5b is connected to the first mold 3; when the driving assembly 5 is connected to the second mold 4, the corresponding elastic member 5b is connected to the second mold 4. The number of elastic members 5b and driving blocks 5a is one-to-one corresponding. If the number of driving blocks 5a is multiple, the number of elastic members 5b is also correspondingly multiple, so as to ensure that after one end of the elastic member 5b is connected to the driving block 5a, the other end can be connected to the corresponding mold one-to-one.

[0078] refer to Figure 3 , 9 -11, this embodiment continues to be described by taking the example that both the first mold 3 and the second mold 4 are movable molds.

[0079] When the driving block 5a is in the first position, the driving block 5a moves the first mold 3 and the second mold 4 away from each other, so that the first mold 3 and the second mold 4 are in a mold separation state. At this time, the first mold 3 and the second mold 4 are opened. The elastic member 5b can be in a free state according to its own parameter setting.

[0080] When the driving block 5a moves from the first position to the second position, the driving block 5a causes the first mold 3 to move from the first position to the second position. Figure 3The right side of the display is along the first direction Figure 3 Move the second mold 4 from the left side of the Figure 3 The left side of the display is along the first direction Figure 3 The first mold 3 and the second mold 4 move to the right as shown, so that the first mold 3 and the second mold 4 move closer to each other.

[0081] When the driving block 5a is in the second position, the first mold 3 and the second mold 4 are in a closed state. At this time, the first mold 3 and the second mold 4 are closed, and the elastic member 5b can be in a stretched state or a free state according to its own parameter design.

[0082] When the driving block 5a moves from the second position to the third position, the driving block 5a connected to the first mold 3 moves from the second position to the third position. Figure 3 The right side of the display is along the first direction Figure 3 The driving block 5a connected to the second mold 4 moves from Figure 3 The left side of the display is along the first direction Figure 3 The elastic member 5b moves to the right side as shown, and during this process and when the driving block 5a is in the third position, the elastic member 5b is deformed, so that the elastic member 5b applies a force to the mold connected to the driving block 5a to move toward the other mold, that is, the elastic member 5b connected to the first mold 3 applies a force to the first mold 3 to move toward the second mold 4, and the elastic member 5b connected to the second mold 4 applies a force to the second mold 4 to move toward the first mold 3, so that the first mold 3 and the second mold 4 can obtain additional clamping force through the elastic member 5b on the basis of closing, so that the first mold 3 and the second mold 4 are closed more tightly, effectively preventing water from leaking from the contact position between the first mold 3 and the second mold 4, and avoiding water leakage of the ice making assembly 2A during the process of preparing ice cubes.

[0083] It is understandable that the clamping force generated by the deformation of the elastic member 5b can have a variety of implementation forms, which can be a thrust along the first direction or a pulling force along the first direction. In the case where the elastic member 5b generates a thrust along the first direction due to deformation, when the driving block 5a moves from the second position to the third position, one end of the elastic member 5b will be squeezed by the driving block 5a, so that the other end of the elastic member 5b applies a thrust to the connected mold, so that the first mold 3 and the second mold 4 are closed. In the case where the elastic member 5b generates a pulling force along the first direction due to deformation, when the driving block 5a moves from the second position to the third position, one end of the elastic member 5b will be stretched by the driving block 5a, so that the other end of the elastic member 5b applies a pulling force to the connected mold, so that the first mold 3 and the second mold 4 are closed.

[0084] refer to Figure 3 , 9 -11, this embodiment takes the elastic member 5b as a compression spring as an example, and explains the situation based on the elastic member 5b generating tension due to deformation.

[0085] When the driving block 5a is in the first position, the first mold 3 and the second mold 4 are in a parting state. At this time, the first mold 3 and the second mold 4 are opened, and the elastic member 5b is in a free state. The elastic member 5b does not exert force on the first mold 3 and the second mold 4.

[0086] When the driving block 5a moves from the first position to the second position, the driving block 5a connected to the first mold 3 will move relative to the first mold 3, so that the elastic member 5b connected to the first mold 3 is stretched, and then the elastic member 5b applies a pulling force to the first mold 3 toward the second mold 4, driving the first mold 3 to move toward the mold closing position. Correspondingly, the driving block 5a connected to the second mold 4 will move relative to the second mold 4, so that the elastic member 5b connected to the second mold 4 is stretched, and then the elastic member 5b applies a pulling force to the second mold 4 toward the first mold 3, driving the second mold 4 to move toward the mold closing position.

[0087] When the driving block 5a moves to the second position, the first mold 3 and the second mold 4 are closed to form a closed state. At this time, the elastic member 5b connected to the first mold 3 and the elastic member 5b connected to the second mold 4 are stretched, so that the first mold 3 and the second mold 4 are respectively driven by the tension applied by the elastic force to move in opposite directions, so that the first mold 3 and the second mold 4 can maintain a closed state.

[0088] When the driving block 5a moves from the second position to the third position and the driving block 5a moves to the third position, the elastic member 5b connected to the first mold 3 and the elastic member 5b connected to the second mold 4 will be further stretched, thereby making the tension applied by the elastic member 5b to the first mold 3 and the tension applied by the elastic member 5b to the second mold 4 further increased, so that the first mold 3 and the second mold 4 can obtain a greater clamping force, so that the first mold 3 and the second mold 4 can be closed more tightly.

[0089] It should be noted that, in the case where one of the first mold 3 or the second mold 4 is a movable mold and the other is a static mold, and in the case where both the first mold 3 and the second mold 4 are movable molds, the drive assembly 5 can be the only power structure that provides moving power to the movable mold, or it can be an additional power structure attached to the movable mold. When the drive assembly 5 is an additional power structure attached to the movable mold, the drive assembly 5 can cooperate with other power structures to enable the two molds to perform opening and closing actions.

[0090] Therefore, this embodiment also provides another example of a refrigerator 100, which includes a box body 1A, an ice-making assembly 2A is arranged in the box body 1A, and the ice-making assembly 2A includes a first mold 3, a second mold 4 and a driving assembly 5, wherein the first mold 3 can be opened and closed with the second mold 4, so that the first mold 3 and the second mold 4 form a mold cavity for preparing ice cubes when they are closed.

[0091] The driving assembly 5 is configured to be able to drive at least the first mold 3 or the second mold 4 to move along the opening and closing direction; and the driving assembly 5 includes a driving block 5a and an elastic member 5b, wherein:

[0092] The driving block 5a is configured to be able to drive the mold driven by the driving assembly 5, that is, the first mold 3 or the second mold 4 to move along the opening and closing direction;

[0093] The elastic member 5b is connected between the driving block 5a and the mold driven by the driving assembly 5, and the elastic member 5b drives the mold driven by the driving assembly 5, that is, the first mold 3 or the second mold 4, to move in the closing direction under the action of the driving block 5a; and

[0094] The driving block 5a is configured to be able to move away from the connected mold along the opening and closing direction of the first mold 3 or the second mold 4 when the first mold 3 and the second mold 4 are closed, so that the elastic member 5b is deformed and the elastic member 5b applies a force to the mold connected to the driving block 5a to move toward the other mold.

[0095] It is understandable that, during the closing process of the first mold 3 and the second mold 4, the driving block 5a can transmit power through the elastic member 5b to accelerate the closing process of the first mold 3 and the second mold 4, or, when the first mold 3 and the second mold 4 are closed, the driving block 5a can move in the first direction, that is, the opening and closing direction of the first mold 3 or the second mold 4, away from the connected mold, and deform the elastic member 5b, so that the corresponding elastic member 5b applies a force to the mold connected to the driving block 5a to move toward the other mold. The process of the driving block 5a driving the elastic member 5b to deform is not repeated here.

[0096] refer to Figure 3In some embodiments, the number of the driving components 5 is two, and the two driving components 5 are connected to the first mold 3 and the second mold 4 respectively; and in the same driving component 5, the number of the driving blocks 5a is two, and the two driving blocks 5a are symmetrically arranged on both sides of the first mold 3 and the second mold 4 in the third direction. By arranging the driving blocks 5a on both sides of the first mold 3 and the second mold 4 respectively, the driving component 5 can make the first mold 3 and the second mold 4 move more smoothly when performing the opening and closing action, thereby ensuring that the first mold 3 and the second mold 4 can always align the closing surface when performing the opening and closing of the mold multiple times, and ensuring that the closing can tightly seal the mold cavity.

[0097] It should be noted that, in other examples, the two driving blocks 5a can also be symmetrically arranged on both sides of the first mold 3 and the second mold 4 in the second direction, so that the two driving blocks 5a can be arranged on the opposite sides of the first mold 3 and the second mold 4. In the case where the two driving blocks 5a are symmetrically arranged on both sides of the first mold 3 and the second mold 4 in the second direction, the driving assembly 5 is arranged on the upper side and the lower side of the first mold 3 and the second mold 4, and the driving assembly 5 needs to avoid the water injection hole 6, the water injection pipe and other structures to avoid interference between the driving assembly 5 and the water injection hole 6, the water injection pipe or other structures.

[0098] refer to Figure 3 In some embodiments, the elastic member 5b is a compression spring, and the elastic member 5b is set to stretch along the opening and closing direction of the first mold 3 and the second mold 4, that is, the first direction, and the direction of the force applied by the elastic member 5b is parallel to the opening and closing direction of the first mold 3 and the second mold 4, so that when the first mold 3 and the second mold 4 are further closed under the action of the force applied by the elastic member 5b, the force applied by the elastic member 5b to the first mold 3 and the second mold 4 can be perpendicular to the closing surface of the first mold 3 and the second mold 4, thereby enabling the first mold 3 and the second mold 4 to move closer to each other while remaining closed, so that the first mold 3 and the second mold 4 can be closed more tightly. In addition, it is avoided that the force applied by the elastic force deviates from the opening and closing direction of the first mold 3 and the second mold 4, so that the first mold 3 and the second mold 4 have a tendency to move in other directions deviating from the first direction, affecting the closing effect of the first mold 3 and the second mold 4.

[0099] refer to Figure 3In some embodiments, a water injection hole 6 is provided at the top of the mold cavity; with the top of the mold cavity to the bottom of the mold cavity as the second direction, the elastic member 5b is arranged in the middle of the mold cavity in the second direction, so that when the elastic member 5b is deformed under the drive of the driving block 5a, the force generated by the elastic member 5b can be evenly distributed to the connected molds, that is, the first mold 3 and / or the second mold 4, so that the first mold 3 and the second mold 4 have a greater clamping force in the circumferential direction of the closing surface, thereby making the first mold 3 and the second mold 4 more tightly connected in the circumferential direction of the closing surface.

[0100] refer to Figure 4 , 6 In some embodiments, the first mold 3 or the second mold 4 includes a cavity block 3a and a mold seat 3b, wherein a space for forming a mold cavity is formed in the cavity block 3a; the mold seat 3b is used to install the cavity block 3a, and a channel 32b arranged along the opening and closing direction of the first mold 3 and the second mold 4 is provided on the mold seat 3b, and the elastic member 5b is installed in the channel 32b. Through the guide limit of the channel 32b, the elastic member 5b can be limited to deform only along the guide direction of the channel 32b. In this way, by limiting the guide direction of the channel 32b to be parallel to the opening and closing direction of the first mold 3 and the second mold 4, it can be ensured that when the elastic member 5b is stretched or squeezed by the driving block 5a, it will deform along the guide direction of the channel 32b, and then exert a force parallel to the opening and closing direction of the first mold 3 and the second mold 4 on the connected molds, that is, the first mold 3 and the second mold 4.

[0101] The cavity block 3a and the mold seat 3b can be detachably connected, so that the first mold 3 and the second mold 4 can select the appropriate cavity block 3a according to the shape of the ice cube to be prepared, thereby preparing ice cubes of the desired shape.

[0102] Considering the efficiency of assembling the elastic member 5b, the channel 32b arranged on the mold base 3b may have a penetrating design, that is, the end surface of the channel 32b facing the outside of the mold base 3b adopts a hollowed-out or hollowed-out design, so that the elastic member 5b can be directly installed in the channel 32b through the hollowed-out or hollowed-out position, and, considering the case where the elastic member 5b adopts a compression spring, the two ends of the channel 32b along the length direction may also be hollowed out or hollowed out, so that the two ends of the elastic member 5b can extend out of the channel 32b and hook on the mold base 3b.

[0103] refer to Figure 4In some embodiments, a positioning block 30b is provided on the mold base 3b, and a positioning hole 50a matching the positioning block 30b is provided on the driving block 5a, and the positioning block 30b can be embedded in the positioning hole 50a, and the driving block 5a moves between the first position, the second position and the third position, so that the positioning block 30b can move in the positioning hole 50a along the length direction of the positioning hole 50a.

[0104] In order to match the moving path of the driving block 5a, the positioning hole 50a is suitably a long hole, and the extension direction of the long hole is parallel to the opening and closing direction of the first mold 3 and the second mold 4, and the specifications and dimensions of the positioning block 30b can be adapted to the specifications and dimensions of the positioning hole 50a, so that when the positioning block 30b moves in the positioning hole 50a, it can move along the opening and closing direction of the first mold 3 and the second mold 4 based on the guidance of the inner wall of the positioning hole 50a, thereby providing auxiliary guidance for the driving block 5a to move along the opening and closing direction of the first mold 3 and the second mold 4.

[0105] refer to Figure 5 In some embodiments, a rack 51a is provided on the top of the driving block 5a, and the driving assembly 5 also includes a gear member 5c, the gear member 5c is meshed with the rack 51a, and the gear member 5c is configured to be rotatable to drive the rack 51a to move along the opening and closing direction of the first mold 3 and the second mold 4.

[0106] The gear member 5c is arranged in one-to-one correspondence with the driving block 5a, and the two gear members 5c in the same driving assembly 5 can be connected by a transmission rod to achieve synchronous rotation. The gear member 5c can be connected to an external output shaft through a coupling to obtain external power, so that the gear member 5c can rotate relative to the rack 51a, thereby driving the rack 51a to move along the opening and closing direction of the first mold 3 and the second mold 4.

[0107] refer to Figure 7 , 8 In some embodiments, the mold base 3b is provided with a guide block 31b to guide the moving direction of the driving block 5a. The guide block 31b has a guide surface 310b arranged along the opening and closing direction of the first mold 3 and the second mold 4. The driving block 5a is attached to the guide surface 310b and slides relative to the mold base 3b.

[0108] The guiding direction of the guide surface 310b should be parallel to the opening and closing direction of the first mold 3 and the second mold 4. With the length direction of the first mold 3 and the second mold 4 as the third direction, the driving block 5a is attached to the guiding surface 310b, which can limit the distance between the driving block 5a and the first mold 3 and the second mold 4 in the third direction, so that when the driving block 5a moves relative to the first mold 3 and the second mold 4, it can maintain the moving path along the first direction and will not deviate from the current moving path in the third direction. In this way, based on the structural design of the collecting seat 3b, the driving block 5a can ensure that it moves along the first direction, that is, the opening and closing direction of the first mold 3 and the second mold 4, and deforms the elastic member 5b in the first direction, so that the elastic member 5b generates a force along the first direction.

[0109] refer to Figure 3 , 5 In some embodiments, a mold splitting portion 52a is provided on the driving block 5a; when the driving block 5a moves toward the first position, the mold splitting portion 52a can be pressed against the mold base 3b, exerting a force on the mold base 3b to move toward the first position. Through the design of the mold splitting portion 52a, when the driving block 5a moves from the third position to the first position, it can directly press against the mold base 3b, and then directly generate force transmission with the mold base 3b, thereby driving the mold base 3b to move toward the first position, so that the first mold 3 and the second mold 4 are separated.

[0110] In summary, the refrigerator 100 provided by the embodiment of the utility model provides a driving assembly 5 in the ice-making assembly 2A, and configures the driving block 5a to be able to move between the first position, the second position and the third position, so that the first mold 3 and the second mold 4 of the ice-making assembly 2A can perform an opening and closing action, and when the first mold 3 and the second mold 4 are closed, a mold cavity for preparing ice cubes is formed, and when the first mold 3 and the second mold 4 are closed, the driving block 5a moves toward the third position or moves away from the connected mold along the opening and closing direction of the first mold 3 or the second mold 4, so that the first mold 3 and the second mold 4 can be opened and closed. When the first mold 3 and the second mold 4 are closed, they have a tendency to move closer to the other mold opposite to them, and the elastic member 5b can be deformed, thereby exerting a force on the mold connected to the driving block 5a to move toward the other mold, so that the first mold 3 and the second mold 4 can move closer to each other and fit together from the closed position, so that the first mold 3 and the second mold 4 can obtain a greater clamping force, so that the first mold 3 and the second mold 4 are closed more tightly, effectively preventing water from leaking from the contact position of the first mold 3 and the second mold 4, and preventing the ice-making assembly 2A from leaking during the preparation of ice cubes. Moreover, after the first mold 3 and the second mold 4 are both provided with the driving assembly 5, the two driving assemblies 5 can make the first mold 3 and the second mold 4 both movable molds, and after the driving block 5a moves to the third position, the first mold 3 and the second mold 4 can both have a tendency to move closer to the other mold opposite to them, so that the two molds can move toward each other and further close, ensuring that the first mold 3 and the second mold 4 are tightly closed.

[0111] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
