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

[0061] 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).

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] Specifically, the ice-making assembly 2A provided in this embodiment includes an outer shell 1, which defines a space for installing and moving a mold inside the outer shell 1, and three travel blocks 2 are respectively arranged on both sides of the outer shell 1 in the width direction of the outer shell 1. When the mold is separated, the travel block 2 can abut against the mold after the mold moves a certain distance, so that the mold stops moving, thereby controlling the movement stroke of the mold located inside the outer shell 1.

[0068] Two molds are arranged in the housing 1, namely, 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 assembly 2A, and can be square, spherical or other shapes.

[0069] As an example of this embodiment, with the top of the mold cavity to the bottom of the mold cavity as the height direction, the first mold 3 and the second mold 4 of this embodiment are molds arranged vertically in the height direction, and both are hemispherical molds. When the first mold 3 and the second mold 4 are closed, the first mold 3 and the second mold 4 can form a vertically arranged mold cavity, and the surface where the first mold 3 and the second mold 4 intersect, that is, the closing surface, is a plane arranged vertically in the height direction. 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.

[0070] refer to Figure 3-4 The ice-making assembly 2A further includes a first driving device 5 and a second driving device 6, wherein, according to the functional parameters of the first mold 3 or the second mold 4, the first driving device 5 is configured to at least drive the first mold 3 or the second mold 4 to open and close, so that the first mold 3 can perform an opening and closing action with the second mold 4; the second driving device 6 is configured to lock the bottom of the mold cavity.

[0071] 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 first driving device 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, and the first driving device 5 is 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 are opened and closed.

[0072] As an example of this embodiment, the second driving device 6 includes a locking block 6a, which is connected to the mold driven by the first driving device and avoids the mold cavity, and the locking block 6a can drive the connected mold to move along the opening and closing direction, so that the bottom of the connected mold squeezes the bottom of the other mold, locking the bottom of the mold cavity.

[0073] It can be understood that, in the case where one of the first mold 3 or the second mold 4 can be a movable mold and the other can be a static mold, the locking block 6a and the first driving device 5 are connected to the movable mold together to drive the movable mold to move relative to the static mold. In the case where both the first mold 3 and the second mold 4 are movable molds, the locking block 6a is connected to the first mold 3 and the second mold 4 to drive the first mold 3 and the second mold 4 to move in opposite directions.

[0074] refer to Figure 3 , Figure 10-11 This embodiment is described by taking the first mold 3 and the second mold 4 as movable molds as an example. In this case, the locking block 6a is connected to the first mold 3 and the second mold 4 at the same time, and can drive the first mold 3 and the second mold 4 to move toward each other.

[0075] The first driving device 5 can drive the first mold 3 and the second mold 4 to open and close each other. When the first driving device 5 drives the first mold 3 and the second mold 4 to move, the second driving device 6 can output power to drive the first mold 3 and the second mold 4 to move, and accelerate the opening and closing speed of the first mold 3 and the second mold 4. Alternatively, the second driving device 6 may not output power, and the first driving device 5 drives the first mold 3 and the second mold 4 to perform the opening and closing action. It should be noted that when the second driving device 6 outputs power, the second driving device 6 needs to cooperate with the first driving device 5 to keep the first mold 3 and the second mold 4 moving steadily and close to form a vertically arranged mold cavity.

[0076] After the first mold 3 and the second mold 4 are closed, the first driving device 5 maintains the current output state to lock the first mold 3 and the second mold 4. At the same time, the second driving device 6 is activated to further move the first mold 3 and the second mold 4 toward each other, so that the bottom of the connected mold squeezes the bottom of the other mold, and further locks the bottom of the mold cavity. In this way, in addition to the locking force applied by the first driving device 5, the bottom of the mold cavity will also obtain the locking force provided by the second driving device 6. Under the protection of the double locking force, the bottom of the mold cavity can have 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, especially the contact position of the bottom of the first mold 3 and the second mold 4, and preventing the ice making assembly 2A from leaking during the process of making ice cubes.

[0077] It can be understood that the function of the second driving device 6 is to further lock the bottom of the first mold 3 and the bottom of the second mold 4 when the first mold 3 and the second mold 4 are closed, so that the bottom of the first mold 3 and the bottom of the second mold 4 are more tightly connected. Therefore, this embodiment also provides another example of a refrigerator 100, which includes a box body 1A and an ice-making assembly 2A, and the ice-making assembly 2A is arranged in the box body 1A to prepare ice cubes; the ice-making assembly 2A includes a first mold 3, a second mold 4, a first driving device 5 and a second driving device 6, wherein,

[0078] The first mold 3 and the second mold 4 can be opened and closed with each other, so that the first mold 3 and the second mold 4 can be closed to form a vertically arranged mold cavity; the first driving device 5 is configured to be able to drive at least one of the molds to move along the opening and closing direction of the two molds to achieve the opening and closing of the first mold 3 and the second mold 4; and,

[0079] The second driving device is configured to be able to lock the bottom of the mold cavity, wherein the second driving device 6 includes a locking block 6a, which is connected to the bottom of the mold driven by the first driving device 5 and is outside the mold cavity, and the locking block 6a is configured to be able to drive the connected mold to move along the opening and closing direction of the first mold 3 and the second mold 4 when the first mold 3 and the second mold 4 are closed, so that the bottom of the connected mold squeezes the bottom of the other mold to lock the bottom of the mold cavity.

[0080] refer to Figure 3-4 As an example of this embodiment, the locking block 6a is penetrated through the first mold 3 and the second mold 4 along the opening and closing direction, and can rotate relative to the first mold 3 and the second mold 4, and the locking block 6a is respectively connected to the first mold 3 and the second mold 4 in a transmission manner, so that the locking block 6a can drive the first mold 3 and the second mold 4 to move along the opening and closing direction when rotating relative to the first mold 3 and the second mold 4.

[0081] Specifically, the locking block 6a is penetrated through the first mold 3 and the second mold 4 along the opening and closing direction, and the locking block 6a is threadedly connected to the first mold 3 and the second mold 4 respectively, and the direction of the thread connecting the locking block 6a to the first mold 3 is opposite to the direction of the thread connecting the locking block 6a to the second mold 4, so that the locking block 6a can rotate to open or close the first mold 3 and the second mold 4.

[0082] It is understandable that when the locking block 6a rotates relative to the first mold 3 and the second mold 4, since the direction of the thread connecting the locking block 6a to the first mold 3 and the direction of the thread connecting the locking block 6a to the second mold 4 are opposite, the locking block 6a can rotate clockwise to open the first mold 3 and the second mold 4, and the locking block 6a can rotate counterclockwise to close the first mold 3 and the second mold 4, or the locking block 6a can rotate counterclockwise to open the first mold 3 and the second mold 4, and the locking block 6a can rotate clockwise to close the first mold 3 and the second mold 4. Moreover, the locking block 6a is threadedly connected to the first mold 3 and the second mold 4, which can make the transmission accuracy of the locking block 6a and the first mold 3 and the second mold 4 higher, and after the first mold 3 and the second mold 4 are closed, the locking force between the bottom of the first mold 3 and the bottom of the second mold 4 is also better.

[0083] refer to Figure 4-5 As an example of this embodiment, the second driving device 6 also includes a second driving tooth 6b as a second driving block. The second driving tooth 6b can drive the locking block 6a to rotate relative to the first mold 3 and the second mold 4, and the locking block 6a is provided with a transmission tooth 60a as a transmission part. The transmission tooth 60a is meshed with the second driving tooth 6b to realize a transmission connection to transmit the power output by the second driving tooth 6b to the locking block 6a.

[0084] The second driving tooth 6b can be installed on the outer shell 1 through the driving motor 6c, and the second driving tooth 6b can be driven by the driving motor 6c to rotate relative to the outer shell 1. It can be understood that gear transmission is only an example of this embodiment, and the second driving block and the locking block 6a can also adopt a screw transmission, a synchronous belt transmission, etc., so that the power output by the second driving block can be transmitted to the locking block 6a, driving the locking block 6a to rotate.

[0085] refer to Figure 6 As an example of this embodiment, the first mold 3 and the second mold 4 are both provided with a molding space 3a and a connecting area 3b, wherein the connecting area 3b is separated from the molding space 3a. When the first mold 3 and the second mold 4 are closed, the molding space 3a of the first mold 3 and the molding space 3a of the second mold 4 are combined to form a mold cavity.

[0086] At the end faces where the first mold 3 and the second mold 4 are closed, that is, the end face of the first mold 3 facing the second mold 4, and the end face of the second mold 4 facing the first mold 3, the connection area 3b is at least arranged on one side of the first mold 3 and the second mold 4 close to their own bottoms, and is located beside the molding space 3a. In this way, the locking block 6a is arranged in the connection area 3b, connected to the first mold 3 and the second mold 4 respectively, and can not interfere with the mold cavity. Moreover, the locking block 6a can be close to the bottom of the first mold 3 and the second mold 4. When the locking block 6a drives the first mold 3 and the second mold 4 to close together, the locking block 6a can apply a locking force to the bottom of the first mold 3 and the second mold 4, so that the bottom of the first mold 3 and the second mold 4 are locked.

[0087] It is understandable that the first driving device 5 can adopt a variety of driving designs to enable the first mold 3 and the second mold 4 to move in opposite directions. As an example of this embodiment, the first driving device includes a first connecting block 5a, a first driving block and an elastic member 5b, wherein:

[0088] There are two first connecting blocks 5a, which are respectively connected to the first mold 3 and the second mold 4, and can move relative to the first mold 3 and the second mold 4 along the opening and closing direction; moreover, there are two elastic members 5b, one end of the elastic member 5b is connected to the first connecting block 5a, and the other end of the elastic member 5b is connected to the mold connected to the first connecting block 5a, and the elastic member 5b can be stretched by the first connecting block 5a and exert a force on the connected mold to move in the closing direction.

[0089] The first driving tooth 5c is connected to the motor as the first driving block, so that the first driving tooth 5c can rotate relative to the first mold 3 and the second mold 4, and drive the first connecting block 5a to move along the opening and closing direction. Matching the first driving tooth 5c, a rack 51a can be provided on the top of the first connecting block 5a, so that the first driving tooth 5c can mesh with the rack 51a, so that the rack 51a can move along the opening and closing direction of the first mold 3 and the second mold 4, thereby moving the first connecting block 5a along the opening and closing direction.

[0090] It can be understood that one end of the elastic member 5b is connected to the first connecting block 5a, and the other end of the elastic member 5b is connected to the mold driven by the first driving device 5. In this way, when the first driving device 5 is connected to the first mold 3, the corresponding elastic member 5b is connected to the first mold 3; when the first driving device 5 is connected to the second mold 4, the corresponding elastic member 5b is connected to the second mold 4.

[0091] refer to Figure 3-4 , Figure 10-11In this embodiment, the elastic member 5b is taken as a compression spring as an example, and the explanation is based on the situation that the elastic member 5b generates tension due to deformation.

[0092] When the first mold 3 and the second mold 4 are opened, the elastic member 5b can be in a free state or a stretched state according to its own parameter settings.

[0093] When the first connecting block 5a moves toward the closing position of the first mold 3 and the second mold 4, the first connecting 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 first connecting 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.

[0094] When the first mold 3 and the second mold 4 are closed, the first mold 3 and the second mold 4 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 the closed state.

[0095] refer to Figure 3 In some embodiments, the number of the first driving devices 5 is two, and the two first driving devices 5 are connected to the first mold 3 and the second mold 4 respectively; and in the same first driving device 5, the number of the first connecting blocks 5a is two, and the two first connecting 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 first connecting blocks 5a on both sides of the first mold 3 and the second mold 4 respectively, the first driving device 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.

[0096] refer to Figure 4 , 6In some embodiments, the first mold 3 or the second mold 4 includes a mold seat 3c and a mold body 3d, wherein the molding space 3a is arranged in the mold seat 3c, and the model body 3d is used to install the mold seat 3c, and the model body 3d is provided with a channel 31d arranged along the opening and closing direction of the first mold 3 and the second mold 4, and the elastic member 5b is installed in the channel 31d. The mold seat 3c and the model body 3d can be detachably connected, so that the first mold 3 and the second mold 4 can select the appropriate model seat 3c according to the shape of the ice cube to be prepared, so as to prepare the ice cube of the desired shape.

[0097] Through the guide limit of the channel 31d, the elastic member 5b can be restricted to deform only along the guide direction of the channel 31d. In this way, by limiting the guide direction of the channel 31d 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 by the first connecting block 5a, it will be deformed along the guide direction of the channel 31d, thereby applying a force parallel to the opening and closing direction of the first mold 3 and the second mold 4 to the connected molds, i.e., the first mold 3 and the second mold 4.

[0098] refer to Figure 6-9 In some embodiments, a positioning block 30d is provided on the model body 3d, and a positioning hole 50a matching the positioning block 30d is provided on the first connecting block 5a, and the positioning block 30d can be embedded in the positioning hole 50a. When the first connecting block 5a moves along the opening and closing direction of the first mold 3 and the second mold 4, the positioning block 30d can move in the positioning hole 50a along the length direction of the positioning hole 50a.

[0099] In order to match the moving path of the first connecting 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 30d can be adapted to the specifications and dimensions of the positioning hole 50a, so that when the positioning block 30d 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 first connecting block 5a to move along the opening and closing direction of the first mold 3 and the second mold 4.

[0100] refer to Figure 6-9 In some embodiments, a split mold portion 52a is provided on the first connection block 5a; when the first connection block 5a moves toward the first position, the split mold portion 52a can be pressed against the model body 3d, exerting a force on the model body 3d to move toward the first position. Through the design of the split mold portion 52a, when the first connection block 5a moves from the third position to the first position, it can directly press against the model body 3d, and then directly generate force conduction with the model body 3d, thereby driving the model body 3d to move toward the first position, so that the first mold 3 and the second mold 4 are separated.

[0101] In summary, the refrigerator 100 provided by the embodiment of the utility model sets the first driving device 5 and the second driving device 6 in the ice-making component 2A, uses the first driving device 5 to close the first mold 3 and the second mold 4 to form a mold cavity for making ice, and uses the second driving device 6 to apply force to the bottom of the mold cavity, so that the mold connected to the locking block 6a can squeeze the other mold, so that the bottom of the first mold 3 and the second mold 4 can be more tightly connected. In this way, the first mold 3 and the second mold 4, especially the bottom of the first mold 3 and the second mold 4, can have 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, especially the contact position of the bottom of the first mold 3 and the second mold 4, so as to avoid water leakage of the ice-making component 2A during the process of preparing ice cubes.

[0102] Moreover, the refrigerator 100 of the present application sets the position of the locking block 6a so that the locking block 6a can avoid the mold cavity and does not interfere with the mold cavity. The locking block 6a will not affect the escape of the ice cubes from the mold cavity. Moreover, the locking block 6a is connected to the bottom of the mold driven by the first drive device 5, and can directly apply force to the bottom of the mold to ensure that the bottom of the mold can obtain the double locking force provided by the first drive device 5 and the second drive device 6, thereby ensuring that the bottom of the mold can be tightly connected. In this way, the sealing of the mold cavity is further improved, so that the mold cavity can hold a larger volume of water, thereby preparing larger ice cubes.

[0103] 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 principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
