[0002] This application claims priority to Chinese Patent Application No. 2024214233862, filed on June 20, 2024, Chinese Patent Application No. 2024214799663, filed on June 26, 2024, and Chinese Patent Application No. 2024109476017, filed on July 15, 2024, the contents of which are hereby incorporated by reference in their entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of refrigeration equipment, in particular to a refrigerator. BACKGROUND

[0004] At present, a refrigerator can be attached with an ice making assembly for providing ice cubes for daily use for users. The ice making assembly is generally arranged in an ice making compartment separated from a refrigerating chamber or a freezing chamber, and ice cubes are formed by condensing water in ice making trays.

[0005] An open ice making tray is one of the common ice making trays. The open ice making tray has a plurality of square cells open to the top. When water for ice making is delivered to the ice making tray by a water injection pipe, the water for ice making fills each of the square cells in the ice making tray, so that each of the square cells is allocated with a certain amount of water for ice making. As the water for ice making absorbs the cold energy inside the refrigerator, the water for ice making in each of the square cells is immediately condensed into ice cubes. Then, the ice making tray is rotated to make the ice cubes inside the ice making tray fall into an ice storage box.

[0006] Since the rotation of the ice making tray needs to occupy a certain space, in order to avoid the interference between the water injection pipe and the ice making tray, the water injection pipe is generally fixed at a high position. As a result, when the water for ice making is injected into the ice making tray from the water injection pipe, the water for ice making has a large potential energy of water flow, so that the water for ice making is easy to splash when falling into the ice making tray, resulting in water droplets adhering to the ice storage box and the outside of the ice making tray. These water droplets will be condensed into ice by absorbing cold energy, which will cause the ice cubes inside the ice storage box to stick together to form large ice cubes, or cause the ice cubes to stick to the ice making tray, affecting the balance of the ice making tray.

[0007] In addition, when the water for ice making falls into the ice making tray through the water outlet of the water injection pipe, it will first concentrate near the water falling point corresponding to the water outlet, and then spread to other areas of the ice making tray. Under the limitation of the surface tension of the liquid, the water for ice making is finally concentrated in the area near the water falling point, resulting in insufficient water in the part of the cells far from the water falling point, and excessive water in the part of the cells close to the water falling point, so that the ice cubes condensed therefrom are stuck together. SUMMARY

[0008] According to various embodiments of the present application, a refrigerator is provided, in which an ice making assembly capable of reducing the height of water injection into an ice making tray can solve the problem of water splashing in a conventional ice making assembly and can solve the problem of ice cubes having different sizes and being easily stuck together during ice making.

[0009] An aspect of the present application can provide a refrigerator, which can include a cabinet and an ice making assembly disposed in the cabinet and capable of making ice from ice making water. The ice making assembly can include an ice making tray for containing the ice making water, the ice making tray having a first position capable of receiving the ice making water and a second position capable of discharging the ice cubes, and the ice making tray being capable of rotating between the first position and the second position; a water injection pipe disposed to be capable of injecting the ice making water into the ice making tray; and a lifting block rotating in synchronization with the ice making tray. The water injection pipe can be disposed on a rotation path of the lifting block, and rotation of the ice making tray from the first position to the second position can cause the lifting block to drive the water injection pipe to gradually move away from the ice making tray, and rotation of the ice making tray from the second position to the first position can cause the water injection pipe to gradually move closer to the ice making tray.

[0010] In one example of the present application, the ice making assembly can further include a mounting bracket to which the ice making tray is rotatably coupled. The mounting bracket can be provided with a first opening, and the water injection pipe can be capable of moving closer to and away from the ice making tray through the first opening. The mounting bracket can be provided with a lifting passage. The water injection pipe can be disposed in the lifting passage and capable of being lifted relative to the mounting bracket along a guide of the lifting passage.

[0011] In one example of the present application, the mounting bracket can further include a bracket body in which the first opening is formed and to which the ice making tray is rotatably coupled, and at least two passage blocks arranged opposite to each other to form the lifting passage. The passage blocks can extend from above the first opening to below the first opening, such that both ends of the lifting passage are located above and below the first opening.

[0012] In one example of the present application, the lifting block can include a rotating portion coupled to the ice making tray and rotating in synchronization with the ice making tray, and a supporting portion disposed on an outer circumferential side of the rotating portion, and an outer side of the supporting portion being coupled to the water injection pipe. The outer side of the supporting portion can have a first supporting portion and a second supporting portion. The first supporting portion is coupled to the water injection pipe when the ice making tray is in the first position, and the second supporting portion is coupled to the water injection pipe when the ice making tray is in the second position. In a direction from the first supporting portion to the second supporting portion, the distance from the outer side of the supporting portion to the rotating portion can gradually increase.

[0013] In one example of the present application, the lifting block can further include a driving portion protruding from the rotating portion and coaxially arranged with the rotating portion. One end of the driving portion is connected to the ice making tray so that the rotating portion is synchronously rotated with the ice making tray.

[0014] In one example of the present application, the lifting block can further include a first positioning portion arranged on a first side of the supporting portion along a rotating direction of the rotating portion. The first positioning portion can protrude from an outer side of the supporting portion. When the ice making tray is in the first position, the first positioning portion can abut against the water injection pipe to fix the water injection pipe. When the ice making tray is rotated from the first position to the second position, the water injection pipe can be driven to move away from the first positioning portion to the supporting portion.

[0015] In one example of the present application, the lifting block can further include a second positioning portion arranged on a second side of the supporting portion along the rotating direction of the rotating portion. When the ice making tray is in the second position, the second positioning portion can abut against the water injection pipe to fix the water injection pipe. When the ice making tray is rotated from the second position to the first position, the water injection pipe can be driven to move away from the second positioning portion to the supporting portion.

[0016] In one example of the present application, the water injection pipe can include an inner pipe member for obtaining ice making water and capable of being fixed relative to the cabinet, and an outer pipe member for obtaining ice making water of the inner pipe member. The outer pipe member can be sleeved on an outer circumferential side of the inner pipe member. The outer pipe member can extend toward the ice making tray to inject ice making water into the ice making tray. The outer pipe member can be connected to the lifting block and capable of being rotated relative to the inner pipe member, so that when the ice making tray is rotated from the first position to the second position, the outer pipe member can gradually move away from the ice making tray. When the ice making tray is rotated from the second position to the first position, the outer pipe member can gradually move toward the ice making tray.

[0017] In one example of the present application, the outer pipe member can include a first pipe portion sleeved on an outer circumferential side of the inner pipe member and capable of being fixed relative to the cabinet, and a second pipe portion connected to the first pipe portion and capable of being rotated relative to the first pipe portion, and the second pipe portion extends toward the ice making tray to inject ice making water into the ice making tray. The inner pipe member can extend from the first pipe portion to the second pipe portion, so that ice making water can enter the second pipe portion from the inner pipe member.

[0018] Another aspect of the present application can provide a refrigerator, which can include a cabinet, and an ice making assembly disposed in the cabinet and capable of making ice with water. The ice making assembly can include an ice making tray for containing the water, and the ice making tray can be rotatable to cause the ice to be ejected. A water injection pipe can be disposed to inject the water into the ice making tray, and the water injection pipe can extend into a rotation area of the ice making tray to be close to the ice making tray. A lifting block can support the water injection pipe and be rotatable in synchronization with the ice making tray. When the ice making tray is rotated to cause the ice to be ejected, the lifting block can be rotated to cause the lifting block to move the water injection pipe away from the ice making tray and out of the rotation area of the ice making tray.

[0019] Another aspect of the present application can provide a refrigerator, which can include a cabinet, and an ice making assembly disposed in the cabinet and capable of making ice with water. The ice making assembly can include an ice making tray having a second opening for injecting the water into the ice making tray, and a rotating part connected to the ice making tray to cause the ice making tray to be rotated by a specified angle. The ice making tray can further include an ice tray assembly for containing the water, an outer wall provided around an outer periphery of the ice tray assembly, and a first partition connected to the ice tray assembly and protruding from a top of the ice tray assembly. The first partition can divide the ice tray assembly into a first compartment and a second compartment, and the water can be injected into the first compartment. When the ice making tray is rotated by the specified angle, the water in the first compartment can flow over the first partition into the second compartment.

[0020] In one example of the present application, the number of the first compartments can be plural, and any one of the first compartments can be in communication with at least one other of the first compartments to allow the water to flow between the first compartments.

A highest water retaining level of the first flow passage can be lower than a highest water retaining level of the first partition.

[0022] In one example of the present application, the first grid can be provided with a second flow channel, which can be in communication with two adjacent first grids. Alternatively, the second grid can be provided with a second flow channel, which can be in communication with two adjacent second grids. The flow direction of the second flow channel can intersect the flow direction of the first flow channel, and the highest water retaining level of the second flow channel can be lower than the highest water retaining level of the first flow channel.

When the ice grid is rotated by a specified angle, the ice-making water located in the third grid can overflow the side wall of the third grid and enter the fourth grid.

[0024] In one example of the present application, the number of third grids can be multiple. The multiple third grids can be arranged in sequence along the direction of the rotation axis of the ice grid. Alternatively, the number of fourth grids can be multiple, and the multiple fourth grids can be arranged in sequence along the direction of the rotation axis of the ice grid.

[0025] In one example of the present application, the third grid can be provided with a second flow channel, which can be in communication with two adjacent third grids. Alternatively, the fourth grid can be provided with a second flow channel, which can be in communication with two adjacent fourth grids. The highest water retaining level of the second flow channel can be lower than the highest water retaining level of the first flow channel and lower than the highest water retaining level between the third grid and the fourth grid.

[0026] In one example of the present application, the ice grid can further include a through channel, which is provided between the ice grid assembly and the outer wall, so that the ice grid assembly is in communication in the direction of the rotation axis of the ice grid. The highest water retaining level of the through channel can be lower than the highest water retaining level of the second flow channel.

[0027] In one example of the present application, the third grid can be provided with a second partition. The extension direction of the second partition can intersect the direction of the rotation axis of the ice grid and protrude from the top of the third grid. The highest water retaining level of the second partition can be higher than the highest water retaining level of the second flow channel.

Alternatively, the hole areas of the water injection holes can gradually increase in the flow direction of the ice making water. A sum of the hole areas of the plurality of water injection holes can be smaller than or equal to a passage area of a cross section of the input section of the water injection pipe.

[0073] The specific embodiments of the present application will now be described in connection with the appended drawings and the following example. The example is intended to illustrate the present application and is not intended to limit the scope of the application.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0077] The refrigerator 100 provided by the embodiments of the present application can have various implementation forms. FIGS. 1-11 are a specific embodiment of the refrigerator 100 of the present application. In the present embodiment, the refrigerator 100 includes a cabinet 101, a refrigeration system (not shown), an air supply system (not shown), and a door body 102.

[0078] The directions described herein are based on the direction of a user facing the refrigerator 100. In the direction of the user facing the refrigerator 100, the left side and the right side are defined. The side of the refrigerator 100 facing the user when the refrigerator 100 is in use is defined as the front side, and the opposite side is defined as the back side. The upper side and the lower side of the refrigerator 100 when the refrigerator 100 is in normal operation are defined as the upward direction and the downward direction.

[0079] As shown in FIGS. 1 and 12, the cabinet 101 is used to form the overall appearance of the refrigerator 100, and the cabinet 101 is generally in the shape of a rectangular frame. The top of the cabinet 101 and the bottom of the cabinet 101 are opposite ends. The height direction of the cabinet 101 is from the top of the cabinet 101 to the bottom of the cabinet 101. The left side of the cabinet 101 and the right side of the cabinet 101 are opposite sides. The width direction of the cabinet 101 is from the left side of the cabinet 101 to the right side of the cabinet 101. The front side of the cabinet 101 and the back side of the cabinet 101 are opposite sides. The thickness direction of the cabinet 101 is from the front side of the cabinet 101 to the back side of the cabinet 101. The cabinet 101 includes an inner container and a cabinet shell. The inner container is disposed in the cabinet shell. An installation space is formed between the inner container and the cabinet shell, which is used to install other components of the refrigerator 100 and to provide a foamed thermal insulation layer. The interior of the inner container forms a refrigeration chamber 103 for placing goods. The refrigeration chamber 103 is provided with a chamber opening. The chamber opening is disposed in the direction of the front side of the cabinet 101. The refrigeration chamber 103 can be in a refrigeration temperature environment, a freezing temperature environment, or a normal temperature environment. The door body 102 is provided at the chamber opening. The door body 102 is in the shape of a straight plate and is disposed on the front side of the cabinet 101. The door body 102 is connected to the cabinet 101 in a manner that can be opened and closed to open or close the refrigeration chamber 103.

[0080] The refrigeration system is used to provide cold air to the refrigeration chamber 103. The refrigeration system generally refers to a closed system composed of a compressor, an evaporator, a condenser, a drying filter, a return air pipe, a throttling device and other components, and a refrigerant. Each component is distributed at different positions of the cabinet 101 according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: after the power cord of the refrigerator 100 is plugged in and the contacts of the temperature controller are turned on, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into high-temperature and high-pressure refrigerant gas by the compressor and then discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, and the temperature drops. The high-temperature and high-pressure refrigerant gas is gradually cooled into a saturated vapor and then into a saturated liquid. The throttling process is as follows: the condensed refrigerant saturated liquid is filtered to remove water and impurities through the drying filter and then flows into the throttling device. The throttling device is used for throttling and pressure reduction, and the refrigerant becomes a wet vapor at a constant temperature and low pressure. The evaporation process is as follows: the wet vapor at a constant temperature and low pressure enters the evaporator, starts to absorb heat and vaporizes, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and changes the refrigerant into a low-temperature and low-pressure gas. The refrigerant from the evaporator returns to the compressor, and the above process is repeated. Through the state change of the refrigerant, energy conversion is realized, the heat in the refrigerator 100 is transferred to the air outside the cabinet, and the refrigeration cycle of the refrigerator 100 is realized.

[0081] The air supply system is installed in the cabinet 101 and is used to provide power for the cold air flow. The air supply system generally includes a fan and an air supply air duct defined in the cabinet 101. In some embodiments, the air inlet end of the air supply air duct is arranged close to the fan, and the air outlet end of the air supply air duct is arranged away from the fan. In other embodiments, the air outlet end of the air supply air duct is arranged close to the fan, and the air inlet end of the air supply air duct is arranged away from the fan. The cabinet 101 further defines an air duct cavity. The air duct cavity is in communication with the air supply air duct and the refrigeration chamber 103, so that the air supply air duct is in communication with the refrigeration chamber 103 through the air duct cavity. It should be noted that the inner container is provided with an air outlet, which is used to communicate the air duct cavity and the refrigeration chamber 103. The cold air generated by the refrigeration system enters the air duct cavity through the air supply air duct by the operation of the fan, and flows to the refrigeration chamber 103 through the air outlet to refrigerate the refrigeration chamber 103. It should be noted that in some embodiments, the air outlet is arranged on the side wall opposite to the chamber opening of the refrigeration chamber 103 or on the side wall adjacent to the chamber opening of the refrigeration chamber 103. It should be noted that the refrigeration system and the air supply system belong to the common technical knowledge in the art, which will not be described here.

[0082] In order to reduce the height of the ice-making water injected into the ice-making grid, reduce the flow potential energy of the ice-making water injected into the ice-making grid, and reduce the impact force of the ice-making water falling into the ice-making grid, so as to effectively solve the problem of water splashing caused by the high arrangement height of the water injection pipe in the traditional ice-making machine assembly, various embodiments of the present application provide an ice-making assembly 104. The ice-making assembly 104 can be installed in the above-mentioned refrigerator 100. Referring to FIGS. 1-11, the ice-making assembly 104 can be provided in the refrigeration chamber 103 to prepare ice cubes. As shown in FIGS. 2 and 3, the ice-making assembly 104 can include an ice-making grid 1 and a water injection pipe 2. The ice-making grid 1 can be used to contain ice-making water 200A, and the ice-making grid 1 can rotate relative to the cabinet 101 to allow ice cubes to be ejected. The water injection pipe 2 can be arranged to inject ice-making water 200A into the ice-making grid 1, and the water injection pipe 2 can extend into the rotating area of the ice-making grid 1 to be close to the ice-making grid 1.

[0083] The ice-making grid 1 provided by the present embodiment can be an open ice-making grid 1. Specifically, at least one square grid 1a can be provided in the ice-making grid 1 to contain ice-making water 200A, and the ice-making grid 1 can have an injection port (e.g., a second opening 1000 below) through which ice-making water 200A can be injected into the square grid 1a. Furthermore, the ice-making grid 1 can have rotating portions 1b connected to both ends in the length direction, and one of the rotating portions 1b can be connected to a drive motor 4 to obtain power output by the drive motor 4, so that the rotating portion 1b can drive the ice-making grid 1 to rotate by a specified angle.

[0084] It can be understood that the number of square grids 1a provided in the ice-making grid 1 can be configured according to the ice-making requirements of the ice-making assembly 104. The more the number of square grids 1a, the more the number of ice cubes that can be prepared by the ice-making assembly 104 at a time. When the number of square grids 1a is large, flow channels can be configured between the square grids 1a for the ice-making water 200A to flow, so that the ice-making water 200A can fill all the square grids 1a.

[0085] Based on the above-mentioned ice-making grid 1 and water injection pipe 2, the ice-making process of the ice-making assembly 104 can be: injecting water into the square grid 1a through the water injection pipe 2, providing cold energy into the refrigeration chamber 103, allowing the water contained in the square grid 1a to freeze into ice cubes, then driving the ice-making grid 1 to rotate by the drive motor 4, rotating the square grid 1a in the ice-making grid 1 to face downward, allowing the ice cubes to be ejected from the ice-making grid 1 and fall into an ice storage box (not shown in the figure) for the user to take.

[0086] As the ice cube tray 1 is driven to rotate by the driving motor 4, the ice cube tray 1 has at least two positions in its rotating path, i.e. a first position and a second position. When the ice cube tray 1 is at the first position, the square grids 1a in the ice cube tray 1 can face upward, so that the ice cube tray 1 can receive the ice-making water 200A. When the ice cube tray 1 is at the second position, the square grids 1a in the ice cube tray 1 can face downward, so that the ice cubes in the ice cube tray 1 can be discharged.

[0087] It should be noted that the first position and the second position are not fixedly defined by angles, but only need to ensure that the ice-making water 200A can be injected into the square grids 1a and stored by the square grids 1a when the ice cube tray 1 is at the first position, and the ice cubes can be discharged from the ice cube tray 1 and fall into the ice storage box when the ice cube tray 1 is at the second position. According to the space in which the ice-making assembly 104 is arranged in the cabinet 101, different ice-making assemblies 104 can have different first positions and second positions, and the ice-making assembly 104 only needs to ensure that the space in which it is arranged has a space for the ice cube tray 1 to rotate between the first position and the second position.

[0088] Referring to FIGS. 2-6 and 8-9, the ice-making assembly 104 according to the present application further comprises a lifting block 3. The lifting block 3 can rotate synchronously with the ice cube tray 1. The water injection pipe 2 can be arranged on the rotating path of the lifting block 3, so that when the ice cube tray 1 rotates from the first position to the second position, the lifting block 3 can drive the water injection pipe 2 to gradually move away from the ice cube tray 1, and when the ice cube tray 1 rotates from the second position to the first position, the water injection pipe 2 can gradually move close to the ice cube tray 1.

[0089] It can be understood that the ice cube tray 1 according to the present application can be an open ice cube tray 1. When the ice-making water 200A is injected, the ice cube tray 1 generally keeps the square grids 1a in an upward state, i.e. the ice cube tray 1 is at the first position. Therefore, when the ice cube tray 1 is at the first position, the water injection pipe 2 is generally arranged above the ice cube tray 1. In this case, when the ice-making water 200A is injected from the water injection pipe 2 into the ice cube tray 1, the ice-making water 200A will generate a certain water flow potential under the action of gravity, so that the ice-making water 200A will hit the side wall of the square grid 1a or the bottom of the square grid 1a, resulting in splashing. The water flow potential is related to the arrangement height of the water injection pipe 2, therefore, reducing the arrangement height of the water injection pipe 2 so that the water injection pipe 2 can be close to the ice cube tray 1 can effectively reduce the water flow potential generated when the ice-making water 200A is injected from the water injection pipe 2 into the ice cube tray 1.

[0090] According to the lifting block 3 of the present application, the water injection pipe 2 can be gradually moved away from the ice making tray 1 when the ice making tray 1 rotates between the first position and the second position. In this way, the water injection pipe 2 can be gradually moved away from the ice making tray 1 when the ice making tray 1 rotates from the first position to the second position, and the water injection pipe 2 can be gradually moved closer to the ice making tray 1 when the ice making tray 1 rotates from the second position to the first position. In other words, when the ice making tray 1 is in the first position, the water injection pipe 2 can be closest to the ice making tray 1. At this time, the height of the water injection pipe 2 to the ice making tray 1 can be reduced, and the potential energy of the water flow of the ice making water 200A flowing from the water injection pipe 2 to the ice making tray 1 can be reduced, thereby reducing the splashing of the ice making water 200A when the ice making water 200A is injected into the ice making tray 1.

[0091] It can be understood that, in order to reduce the potential energy of the water flow of the ice making water 200A, the water injection pipe 2 can be as close to the ice making tray 1 as possible. When the ice making tray 1 is in the first position, the distance between the water injection pipe 2 and the ice making tray 1 can be adjusted according to the number of the ice making tray 1, the water injection amount of the water injection pipe 2 per unit time, the ice making time, and other parameters, so that the water injection pipe 2 can be in a suitable position, and the ice making water 200A can be smoothly injected into the ice making tray 1, and excessive splashing can be avoided.

[0092] Of course, when the water injection pipe 2 is close to the ice making tray 1, the water injection pipe 2 generally enters the rotating area of the ice making tray 1, so that the water injection pipe 2 can be close enough to the ice making tray 1. When the ice making tray 1 rotates from the first position to the second position, the ice making tray 1 needs to rotate itself. If the water injection pipe 2 is fixed, the water injection pipe 2 will interfere with the ice making tray 1, and the ice making tray 1 cannot rotate. Therefore, the lifting block 3 of the present application can move the water injection pipe 2 away from the rotating area of the ice making tray 1 when the ice making tray 1 rotates from the first position to the second position and when the ice making tray 1 is in the second position, so as to ensure that the water injection pipe 2 does not affect the normal ice making action of the ice making tray 1. For example, the lifting block 3 can drive the water injection pipe 2 to move up and down relative to the ice making tray 1, so as to move the water injection pipe 2 closer to and away from the ice making tray 1. In this way, the potential energy of the water flow of the ice making water 200A can be reduced, thereby reducing the splashing of the ice making water 200A when the ice making water 200A is injected, and the normal ice making action of the ice making tray 1 can be ensured, so that the ice making assembly 104 of the present application is easy to operate, splashing is less likely to occur, and the ice making efficiency is high.

[0093] It can be understood that the minimum distance between the water injection pipe 2 and the ice making tray 1 when the water injection pipe 2 is close to the ice making tray 1, and the maximum distance between the water injection pipe 2 and the ice making tray 1 when the water injection pipe 2 is far away from the ice making tray 1 are indefinite, and the ice making assembly 104 can be adjusted according to the environment in which the ice making assembly 104 is located and the specifications and sizes of the ice making tray 1, the water injection pipe 2 and other components. Since the ice making tray 1 adopts an open design, the ice making tray 1 needs to rotate to make the ice cubes fall out, and therefore the ice making tray 1 will have a rotating area formed based on the rotation. In this way, the present application also provides a refrigerator 100. In the refrigerator 100, the minimum distance and the maximum distance between the water injection pipe 2 and the ice making tray 1 can be limited. The refrigerator 100 can include a cabinet 101 and the ice making assembly 104 as described above. The ice making assembly 104 can be arranged in the cabinet 101 to prepare the ice making water 200A into ice cubes. The ice making assembly 104 can include the ice making tray 1, the water injection pipe 2 and the lifting block 3.

[0094] The ice making tray 1 can be used to contain the ice making water 200A, and the ice making tray 1 is capable of rotating to make the ice cubes fall out. The water injection pipe 2 can be arranged to be capable of injecting the ice making water 200A into the ice making tray 1, and the water injection pipe 2 can extend into the rotating area of the ice making tray 1 to be close to the ice making tray 1. The lifting block 3 can support the water injection pipe 2 and is capable of rotating synchronously with the ice making tray 1. The ice making tray 1 is capable of driving the lifting block 3 to rotate when the ice making tray 1 rotates to make the ice cubes fall out, and the lifting block 3 drives the water injection pipe 2 to move away from the ice making tray 1 and out of the rotating area of the ice making tray 1.

[0095] Compared with the conventional water injection pipe fixed at a high position, the water injection pipe 2 of the ice making assembly 104 according to the present application can enter the rotating area of the ice making tray 1, so that the water outlet of the water injection pipe 2 is closer to the ice making tray 1. In this way, the ice making water 200A injected from the water injection pipe 2 into the ice making tray 1 will generate smaller water flow potential energy, and the splashing of the ice making water 200A falling into the ice making tray 1 can be effectively reduced. Moreover, the water injection pipe 2 can leave the rotating area of the ice making tray 1 when the ice making tray 1 rotates to make the ice cubes fall out, so that the water injection pipe 2 will not affect the normal ice falling action of the ice making tray 1, making the ice making assembly 104 according to the present application easy to operate, less likely to have splashing problems and high in ice making efficiency.

[0096] Referring to FIGS. 2 to 7, considering the installation and positioning of the ice making assembly 104 in the refrigeration cavity 103, the ice making assembly 104 further includes a mounting bracket 5 to enable the ice making assembly 104 to be fixed in the refrigeration cavity 103. The driving motor 4 can be mounted in the mounting bracket 5. The ice making tray 1 can be rotatably connected to the mounting bracket 5, so that the ice making tray 1 is capable of rotating relative to the mounting bracket 5. The top of the mounting bracket 5 can be provided with a first opening 5a. The water injection pipe 2 is capable of entering the interior of the mounting bracket 5 through the first opening 5a. Under the action of the lifting block 3, the water injection pipe 2 is capable of approaching and moving away from the ice making tray 1 through the first opening 5a.

[0097] In order to guide the movement of the water injection pipe 2 to approach and move away from the ice making tray 1, so that the water injection pipe 2 moves along a predetermined path, a lifting channel 5b can be arranged in the mounting bracket 5. The lifting channel 5b can be arranged to extend in the up-down direction. The water injection pipe 2 can be arranged in the lifting channel 5b and can be lifted relative to the mounting bracket 5 under the guidance of the lifting channel 5b, so that when the lifting block 3 drives the water injection pipe 2 to approach and move away from the ice making tray 1, the water injection pipe 2 will move in the lifting channel 5b and keep effective connection with the lifting block 3, thereby ensuring effective water injection, effective ice discharge and other actions of the ice making assembly 104.

[0098] As an example according to the present application, the mounting bracket 5 can include a bracket body 5c and two channel blocks 5d. The first opening 5a can be formed in the bracket body 5c. The ice making tray 1 can be rotatably connected in the bracket body 5c. The two channel blocks 5d can be arranged oppositely to form the lifting channel 5b. The channel blocks 5d can extend from above the first opening 5a to below the first opening 5a, that is, the two ends of the lifting channel 5b can be located above and below the first opening 5a.

[0099] Under the restriction of the channel blocks 5d, the water injection pipe 2 will be clamped by the two channel blocks 5d during the process of approaching and moving away from the ice making tray 1, and will not deviate from the lifting channel 5b. Moreover, since the channel blocks 5d extend from above the first opening 5a to below the first opening 5a, so that the two ends of the lifting channel 5b are located above and below the first opening 5a, when the ice making tray 1 is in the first position, the water injection pipe 2 can be in the lifting channel 5b below the first opening 5a to approach the ice making tray 1, and when the ice making tray 1 rotates from the first position to the second position, the water injection pipe 2 can move along the lifting channel 5b from below the first opening 5a to above the first opening 5a. Since the ice making tray 1 is rotatably connected in the mounting bracket 5, the water injection pipe 2 moving to above the first opening 5a will be out of the rotating area of the ice making tray 1, ensuring that the water injection pipe 2 will not hinder the rotation of the ice making tray 1.

[0100] Referring to FIGS. 2-6 and 8-9, as an example according to the present application, the lifting block 3 can include a rotating part 3a and a supporting part 3b. The outer contour of the rotating part 3a can be circular. The rotating part 3a can be connected to the ice making tray 1 and rotate synchronously with the ice making tray 1. The supporting part 3b can be arranged on the outer periphery side of the rotating part 3a, and the outer side of the supporting part 3b can be connected (e.g., contacted) to the bottom of the water injection pipe 2 to support the water injection pipe 2.

[0101] As the lifting block 3 rotates, the connection position of the lifting block 3 to the water injection pipe 2 can be different. According to the position of the lifting block 3 and the connection of the lifting block 3 to the water injection pipe 2, the outer side of the supporting portion 3b can have a first supporting portion 30b and a second supporting portion 31b. In other embodiments of the present application, the first supporting portion 30b and the second supporting portion 31b can also be referred to as a first supporting position 30b and a second supporting position 31b. In this way, when the ice making tray 1 is in the first position, the first supporting portion 30b can be connected to the water injection pipe 2, and when the ice making tray 1 is in the second position, the second supporting portion 31b can be connected to the water injection pipe 2. From the first supporting portion 30b to the second supporting portion 31b, the distance from the outer side of the supporting portion 3b to the rotating portion 3a can gradually increase.

[0102] When the ice making tray 1 is in the first position, the first supporting portion 30b of the lifting block 3 is connected to the bottom of the water injection pipe 2 to support the water injection pipe 2. The water injection pipe 2 itself stays in the lifting channel 5b under the action of gravity and is pressed on the first supporting portion 30b. As the ice making tray 1 rotates together with the lifting block 3, the connection position of the lifting block 3 to the water injection pipe 2 is switched from the first supporting portion 30b to the second supporting portion 31b. In this process, the water injection pipe 2 itself continues to stay in the lifting channel 5b under the action of gravity and is pressed on the outer side of the supporting portion 3b. Since the distance from the outer side of the supporting portion 3b to the rotating portion 3a gradually increases from the first supporting portion 30b to the second supporting portion 31b, after the connection position of the lifting block 3 to the water injection pipe 2 is switched from the first supporting portion 30b to the second supporting portion 31b, the distance from the water injection pipe 2 to the rotating portion 3a increases, and since the lifting block 3 rotates coaxially with the ice making tray 1, the distance from the water injection pipe 2 to the ice making tray 1 also increases, so that the water injection pipe 2 can be driven away from the ice making tray 1 by the lifting block 3. And when the lifting block 3 reverses, the connection position of the lifting block 3 to the water injection pipe 2 is switched from the second supporting portion 31b to the first supporting portion 30b, so that the water injection pipe 2 is close to the ice making tray 1.

[0103] It can be understood that the distance from the outer side of the supporting portion 3b to the rotating portion 3a can be associated with the distance between the water injection pipe 2 and the ice making tray 1. By adjusting the distance from the first supporting portion 30b to the rotating portion 3a and the distance from the second supporting portion 31b to the rotating portion 3a, the water injection pipe 2 can be below the first opening 5a when the ice making tray 1 is in the first position, thereby being close to the ice making tray 1, and the water injection pipe 2 can be moved above the first opening 5a when the ice making tray 1 is in the second position, thereby being away from the ice making tray 1 to avoid interference with the ice making tray 1.

[0104] Referring to FIG. 9, as an example according to the present application, in order to enable the lifting block 3 to rotate synchronously with the ice making tray 1 and enable the lifting block 3 to rotate coaxially with the ice making tray 1, the lifting block 3 can include a driving portion 3c. The driving portion 3c can protrude from the rotating portion 3a and be arranged coaxially with the rotating portion 3a. Also, one end of the driving portion 3c can be connected to the ice making tray 1 to enable the rotating portion 3a to rotate synchronously with the ice making tray 1.

[0105] In order not to occupy the rotating area of the ice making tray 1, the lifting block 3 can be arranged outside the mounting bracket 5. In this way, one end of the driving portion 3c can pass through the mounting bracket 5 and extend into the mounting bracket 5 to be connected to the ice making tray 1. In this case, the rotating portion 3a and the supporting portion 3b can be arranged outside the mounting bracket 5, and the space outside the mounting bracket 5 can be used to adjust the lifting of the water injection pipe 2.

[0106] Referring to FIGS. 2-6 and 8-9, as an example according to the present application, the lifting block 3 can further include a first positioning portion 3d. The first positioning portion 3d can be arranged on the first side of the supporting portion 3b along the rotating direction of the rotating portion 3a and abut against the supporting portion 3b. The first positioning portion 3d can protrude outward from the outside of the supporting portion 3b along the radial direction of the rotating portion 3a. Also, when the ice making tray 1 is in the first position, the first positioning portion 3d can abut against the water injection pipe 2 to limit the displacement of the water injection pipe 2. When the ice making tray 1 rotates from the first position to the second position, the water injection pipe 2 can be driven to move away from the first positioning portion 3d to the supporting portion 3b.

[0107] The first positioning portion 3d is used to support the water injection pipe 2 when the ice making tray 1 is in the first position to limit the position of the water injection pipe 2. According to the rotating direction of the ice making tray 1 and the lifting block 3, the first positioning portion 3d can generally be arranged on the first side of the first supporting portion 3b. When the ice making tray 1 is in the first position, the first positioning portion 3d and the supporting portion 3b can both be below the water injection pipe 2 to support the water injection pipe 2, and since the first positioning portion 3d protrudes outward from the outside of the supporting portion 3b, a V-shaped clamping groove can be formed between the first positioning portion 3d and the supporting portion 3b to limit the displacement of the water injection pipe 2 in the lifting channel 5b.

[0108] Of course, the lifting block 3 can also include a second positioning portion 3e. The second positioning portion 3e can be arranged on the second side of the supporting portion 3b along the rotating direction of the rotating portion 3a. The second positioning portion 3e can be located on the two sides of the supporting portion 3b, respectively, with the first positioning portion 3d, to limit the position of the water injection pipe 2 when it moves away from the ice making tray 1. Similar to the first positioning portion 3d, the second positioning portion 3e can abut against the water injection pipe 2 when the ice making tray 1 is in the second position to limit the displacement of the water injection pipe 2, and when the ice making tray 1 rotates from the second position to the first position, the water injection pipe 2 can be driven to move away from the second positioning portion 3e to the supporting portion 3b.

[0109] By setting the first positioning part 3d and the second positioning part 3e on the lifting block 3, the moving position of the water injection pipe 2 in the lifting channel 5b can be limited, so that the water injection pipe 2 can be kept fixed at a position during the rotation of the ice cube tray 1, and will not deviate from the position during water injection to cause splashing, nor will it enter the rotating area of the ice cube tray 1 during ice discharge of the ice cube tray 1 to cause the water injection pipe 2 to interfere with the ice cube tray 1.

[0110] Referring to FIGS. 10-11, as an example according to the present application, the water injection pipe 2 can include an inner pipe 2a and an outer pipe 2b. The inner pipe 2a is used to obtain ice-making water 200A and can be kept fixed relative to the cabinet 101. The outer pipe 2b is used to obtain the ice-making water 200A of the inner pipe 2a. The outer pipe 2b can be sleeved on the outer circumferential side of the inner pipe 2a and extends towards the ice cube tray 1 to inject the ice-making water 200A into the ice cube tray 1. Moreover, the outer pipe 2b can be connected to the lifting block 3 and can rotate relative to the inner pipe 2a, so that when the ice cube tray 1 rotates from the first position to the second position, the outer pipe 2b gradually moves away from the ice cube tray 1, and when the ice cube tray 1 rotates from the second position to the first position, the outer pipe 2b gradually moves towards the ice cube tray 1.

[0111] It can be understood that since the outer pipe 2b is sleeved on the outer circumferential side of the inner pipe 2a, the inner diameter of the inner pipe 2a is smaller than the inner diameter of the outer pipe 2b, and in order to ensure that the outer pipe 2b can rotate relative to the inner pipe 2a, a gap is generally left between the outer pipe 2b and the inner pipe 2a. In this way, when the ice-making water 200A flows from the inner pipe 2a into the outer pipe 2b, it is transferred from the smaller inner diameter channel of the inner pipe 2a to the larger inner diameter channel of the outer pipe 2, which can slow down the flow rate of the ice-making water 200A. In addition, the outer pipe 2b can be close to the ice cube tray 1, so the ice-making water 200A can fall into the ice cube tray 1 at a lower flow rate and a lower height, further reducing the potential energy of the ice-making water 200A and avoiding splashing. Moreover, the lifting block 3 is connected to the outer pipe 2b, and during the ice-making process of the ice-making assembly 104, the inner pipe 2a can be kept fixed relative to the cabinet 101. In this way, the pipeline of the refrigerator 100 can be kept sealed with the inner pipe 2a to avoid water leakage.

[0112] As an example according to the present application, the outer pipe 2b can include a first pipe part 20b and a second pipe part 21b. In an example of the present application, the first pipe part 20b and the second pipe part 21b can be sleeved together and can move relative to each other to adjust the length of the outer pipe 2b. By making the outer pipe 2b have a split structure and a variable length, the weight of the outer pipe 2b is further reduced, and since the length of the outer pipe 2b can be shortened, the space required for the water injection pipe 2 to lift is smaller, which is more conducive to the arrangement of the ice-making assembly 104.

[0113] The first pipe part 20b can be sleeved on the outer circumferential side of the inner pipe 2a and can be fixed relative to the cabinet 101. The second pipe part 21b can be connected to the first pipe part 20b and can rotate relative to the first pipe part 20b. The second pipe part 21b extends towards the ice making tray 1 to inject the ice making water 200A into the ice making tray 1. In addition, the inner pipe 2a extends from the first pipe part 20b to the second pipe part 21b, so that the ice making water 200A can enter the second pipe part 21b from the inner pipe 2a.

[0114] In summary, according to the refrigerator 100 of the present application, by arranging the lifting block 3 connected to the ice making tray 1, the rotation of the ice making tray 1 can drive the lifting block 3 to rotate synchronously, that is, the ice making tray 1 can drive the lifting block 3 to rotate between the first position and the second position. In this way, by cooperating the lifting block 3 with the water injection pipe 2, the ice making tray 1 can drive the lifting block 3 to drive the water injection pipe 2 to gradually move away from the ice making tray 1 when the ice making tray 1 rotates from the first position to the second position, and the ice making tray 1 can drive the water injection pipe 2 to gradually move close to the ice making tray 1 when the ice making tray 1 rotates from the second position to the first position. The water injection pipe 2 can move relative to the ice making tray 1 to move close to and away from the ice making tray 1. When the ice making tray 1 is in the first position, the water injection pipe 2 can be closest to the ice making tray 1. Compared with the conventional water injection pipe fixed at a high position, in the present application, the ice making water 200A can fall into the ice making tray 1 from a lower position, thereby reducing the potential energy of the ice making water 200A and reducing the splashing of the ice making water 200A. When the ice making tray 1 needs to rotate to the second position to make the ice cubes fall out, the water injection pipe 2 can move away from the rotating area of the ice making tray 1, so as to ensure that the water injection pipe 2 does not interfere with the rotation process of the ice making tray 1, so that the ice making tray 1 can rotate smoothly and realize efficient ice making.

[0115] In addition, the lifting block 3 of the present application is provided with the first positioning block and the second positioning block, so that the water injection pipe 2 can be fixed at the current position when the ice making tray 1 is in the first position or the second position. Therefore, when the ice making tray 1 is in the first position, the water injection pipe 2 can extend into the rotating area of the ice making tray 1 to enable the ice making water 200A to fall into the ice making tray 1 smoothly. When the ice making tray 1 is in the second position, the water injection pipe 2 can exit the rotating area of the ice making tray 1 to ensure that the water injection pipe 2 does not affect the rotation of the ice making tray 1. In addition, the water injection pipe 2 of the present application is provided with the inner pipe 2a and the outer pipe 2b, and the outer pipe 2b is divided into the first pipe part 20b and the second pipe part 21b, so that one end of the water injection pipe 2 can be stably connected to the pipeline system of the cabinet 101 to ensure stable delivery of the ice making water 200A, and the other end of the water injection pipe 2 can move relative to the ice making tray 1 to move close to and away from the ice making tray 1, thereby reducing the potential energy of the ice making water 200A and reducing the splashing of the ice making water 200A.

[0116] To solve the problem of ice cubes of different sizes and easy to stick together when ice is made by using an open ice tray in the conventional technology, and to be able to uniformly distribute the ice-making water grid, according to some embodiments of the present application, an ice-making assembly 104 is also provided as shown in FIGS. 13 to 24.

[0117] Referring to FIGS. 12 to 24, the ice-making assembly 104 is provided in the refrigeration chamber 103 of the refrigerator 100 as described above to make ice cubes. In general, the ice-making process of the ice-making assembly 104 is to inject water into the ice-making tray 1 inside the ice-making assembly 104 for containing liquid, and to provide cold to the refrigeration chamber 103, so that the water contained in the ice-making tray 1 is frozen into ice cubes, and then the ice cubes are dropped from the ice-making tray 1 to the ice storage box (not shown) for the user to take.

[0118] The ice-making assembly 104 shown in FIGS. 13 to 24 can be an open ice-making tray 1. Specifically, the ice-making assembly 104 can include the ice-making tray 1. The ice-making tray 1 can have a second opening 1000 through which ice-making water 200A can be injected into the inside of the ice-making tray 1, and both ends of the ice-making tray 1 in the length direction are connected with rotating parts 1b, and one of the rotating parts 1b is connected with the driving motor 4 to obtain the power output by the driving motor 4, so that the rotating part 1b can drive the ice-making tray 1 to rotate by a specified angle. Here, the length direction of the ice-making tray 1 can be referred to as the first direction X1-X2. As shown in FIG. 14, the first direction X1-X2 can be defined as the length direction of the ice-making tray 1, the direction perpendicular to the length direction of the ice-making tray 1 can be defined as the second direction Y1-Y2, and the direction perpendicular to both the first direction X1-X2 and the second direction X1-X2 can be defined as the third direction Z1-Z2. When viewed in the direction of FIG. 14, the second direction Y1-Y2 can also be referred to as the left-right direction, and the third direction Z1-Z2 can also be referred to as the vertical direction.

[0119] Referring to FIGS. 14 to 19, the ice-making tray 1 according to the present application can further include an ice tray assembly 300 inside the ice-making tray 1 and an outer wall 400 arranged around the outer periphery of the ice tray assembly 300. The ice tray assembly 300 can include a plurality of grids for containing ice-making water 200A injected into the inside of the ice-making tray 1. The outer wall 400 can be connected to the outer edge of the ice tray assembly 300. In other words, the outer wall 400 can be arranged around the ice tray assembly 300 and can extend beyond the top of the ice tray assembly 300, thereby enclosing the second opening 1000 of the ice-making tray 1 to enable the ice-making water 200A to be injected into the inside of the ice-making tray 1 through the second opening 1000. In this way, when the ice-making tray 1 is driven to rotate by a specified angle by the rotating part 1b, it can also be ensured that the ice-making water 200A can remain in the ice-making tray 1, avoiding leakage of the ice-making water 200A from the ice-making tray 1.

[0120] In the ice-making process of the ice-making assembly according to the present application, the ice-making tray 1 can be initially placed horizontally, so that the ice-making water 200A can be injected into the interior of the ice-making tray assembly 300 and stored in each of the cells. Since the injection point is generally in a partial area of the ice-making tray 1, the ice-making water 200A cannot cover the entire ice-making tray 1, and thus the ice-making water 200A is often concentrated in a portion of the cells, so that the water storage capacity of another portion of the cells is insufficient. Therefore, after the ice-making water 200A is stable and no longer flows, the ice-making tray 1 can be rotated by a specified angle under the action of the driving motor 4, so that the ice-making tray 1 is rotated toward the direction of the cells with less water storage capacity, so as to make the ice-making water 200A flow again in the ice-making tray 1. In this way, the ice-making water 200A in the cells with more water storage capacity flows to the cells with less water storage capacity under the action of gravity. In this way, when the ice-making tray 1 is reset to the horizontal position, the ice-making water 200A can be more evenly distributed in each of the cells of the ice-making tray 1.

[0121] It can be understood that the aforementioned specified angle, the size of the ice tray assembly 300, the height to which the outer wall 400 extends, and the injection amount of the ice-making water 200A are interrelated. For example, in the case of a certain size of the ice tray assembly 300, the greater the specified angle by which the ice-making tray 1 is rotated, the higher the height to which the outer wall 400 needs to extend beyond the first opening 1000, or the greater the injection amount of the ice-making water 200A, the higher the height to which the outer wall 400 needs to extend beyond the first opening 1000. However, it can be understood that the upper limit of the height to which the outer wall 400 extends should not affect the ice cubes from being separated from the ice-making tray 1. Generally, the specified angle by which the ice-making tray 1 is rotated during the preparation of ice cubes can be selected between 10° and 15°. In this way, the ice-making tray 1 can ensure that the ice-making water 200A does not escape from the ice-making tray 1 when the ice-making tray 1 is rotated by the specified angle during the ice-making process, and can also ensure that the ice-making water 200A can flow between the cells when the ice-making tray 1 is rotated, so that the ice-making water 200A can be more evenly distributed in each of the cells.

[0122] Referring to FIGS. 14 to 19, the ice tray assembly 300 can further include a first partition 300a. The first partition 300a can be connected to the ice tray assembly 300 and can protrude from the top of the ice tray assembly 300, so that the ice tray assembly 300 is divided into a first cell 300b and a second cell 300c. When the ice-making water 200A is injected into the interior of the ice-making tray 1, the first cell 300b can be configured to first receive the ice-making water 200A.

[0123] It can be understood that the positions of the first compartment 300b and the second compartment 300c can be flexibly set. In the ice-making tray 1 shown in FIGS. 14 and 15, the first compartment 300b can be on the Y1 side of the first partition 300a in the Y1-Y2 direction, for example, on the left side of the first partition 300a, and the second compartment 300c can be on the Y2 side of the first partition 300a in the Y1-Y2 direction, for example, on the right side of the first partition 300a. In other embodiments, the first compartment 300b can be on the Y2 side of the first partition 300a in the Y1-Y2 direction, for example, on the right side of the first partition 300a, and the second compartment 300c can be on the Y1 side of the first partition 300a in the Y1-Y2 direction, for example, on the left side of the first partition 300a. That is, the first compartment 300b and the second compartment 300c are divided by the first partition 300a, and the first compartment 300b and the second compartment 300c can be respectively on the two sides of the first partition 300a, and the first compartment 300b and the second compartment 300c are only used to distinguish each other and are not used to define the setting positions thereof. The first compartment 300b and the second compartment 300c can have the same structure. In this case, for the ice-making tray 1 according to the present application, when the ice-making water 200A is injected from outside the ice-making tray 1 to the inside of the ice-making tray 1, the compartment corresponding to the region where the injection point is located is the first compartment 300b, and the compartment corresponding to the first compartment 300b and separated from the first partition 300a is the second compartment 300c. In some examples, the first compartment 300b and the second compartment 300c can also have different structures. As shown in FIG. 18, the depth of the first compartment 300b can be greater than the depth of the second compartment 300c. In the case where the top of the first compartment 300b is flush with the top of the second compartment 300c, the depth of the first compartment 300b can be greater than the depth of the second compartment 300c by making the bottom of the second compartment 300c higher than the bottom of the first compartment 300b.

[0124] The first compartment 300b can be arranged adjacent to the second compartment 300c. The first partition 300a can be disposed on the top of the abutting wall between the first compartment 300b and the second compartment 300c, so that the first partition 300a can protrude from the top of the ice cube tray assembly 300. Since the first partition 300a can protrude from the top of the ice cube tray assembly 300, the highest water retaining level formed by the first partition 300a must be higher than the highest water retaining level of the first compartment 300b or the second compartment 300c. In this way, the ice-making water 200A can only flow to the second compartment 300c after filling the first compartment 300b, and then overflow the first partition 300a. It can be understood that the highest water retaining level mentioned herein refers to the maximum water level height that the ice-making water 200A intercepted by the first partition 300a can reach. When the water level height of the first compartment 300b exceeds the highest water retaining level of the first partition 300a, the ice-making water 200A can overflow the first partition 300a from the first compartment 300b into the second compartment 300c.

[0125] Referring to FIGS. 20 to 22, after the ice-making water 200A is injected into the first compartment 300b, depending on the injection amount of the ice-making water 200A, the ice-making water 200A can be stored entirely in the first compartment 300b, or can be partially stored in the first compartment 300b and partially stored in the second compartment 300c, but the water amount of the ice-making water 200A stored in the first compartment 300b is at least not less than the water amount of the ice-making water 200A stored in the second compartment 300c. After the ice-making water 200A stabilizes and no longer flows, the ice cube tray 1 can be rotated by a specified angle under the action of the driving motor 4, so that the first partition 300a rotates by a specified angle. In this case, the height of the first partition 300a in the vertical direction or the third direction Z1-Z2 is reduced, so that the current water retaining height of the first partition 300a is lower than the water level height of the first compartment 300b. Part of the ice-making water 200A stored in the first compartment 300b immediately overflows the first partition 300a and enters the second compartment 300c.

[0126] When the ice cube tray 1 is reset to the horizontal position, the first partition 300a is also reset, so that the current water retaining height of the first partition 300a returns to the highest water retaining level. In this way, the ice-making water 200A located in the second compartment 300c will be left in the second compartment 300c after the ice cube tray 1 is reset by a certain angle, because it cannot continue to pass through the first partition 300a. In this way, part of the ice-making water 200A originally located in the first compartment 300b can flow into the second compartment 300c due to the rotating action of the ice cube tray 1. Compared with the initial distribution state of the ice-making water 200A injected into the ice cube tray 1, the ice-making water 200A can be more evenly distributed in the first compartment 300b and the second compartment 300c.

[0127] Referring to FIGS. 14 to 19, as an example according to the present application, the number of the first cells 300b is plural, and the plural first cells 300b are arranged in a rectangular array. According to the size of the space in which the ice-making tray 1 is arranged, the number of rows and the number of columns of the first cells 300b can be configured so that the arrangement of the plural first cells 300b can be adapted to the space in which the ice-making tray 1 is arranged. Also, in the plural first cells 300b, any one of the first cells 300b is in communication with at least one other first cell 300b so that the ice-making water 200A can flow between the plural first cells 300b, thereby enabling the plural first cells 300b to be filled with the ice-making water 200A when the ice-making water 200A is injected into the inside of the ice-making tray 1.

[0128] According to the injection amount of the ice-making water 200A and the specification of the ice-making tray 1, the number of the second cells 300c corresponding to the first cells 300b can also be plural, and the plural second cells 300c can be arranged in a rectangular array. Also, in the plural second cells 300c, any one of the second cells 300c is in communication with at least one other second cell 300c so that the ice-making water 200A can flow between the plural second cells 300c, thereby enabling the plural second cells 300c to be filled with the ice-making water 200A when the ice-making water 200A overflows the first partition 300a and enters the second cells 300c. The arrangement of the second cells 300c can be the same as that of the first cells 300b, and thus a separate illustration is not provided.

[0129] The manner in which the first cells 300b are in communication with each other is various. Referring to FIGS. 14 to 19, as an example according to the present application, the first cells 300b can be provided with first flow-through grooves 500 on the side walls thereof. The first flow-through grooves 500 communicate between adjacent two first cells 300b in the direction of the rotation axis of the ice-making tray 1, i.e., in the first direction X1-X2 shown in FIG. 14. The highest water-stopping level of the first flow-through grooves 500 can be lower than that of the first partition 300a. Also, the first cells 300b can be provided with second flow-through grooves 600. The second flow-through grooves 600 can communicate between adjacent two first cells 300b. The flow direction of the second flow-through grooves 600 can intersect the flow direction of the first flow-through grooves 500. The highest water-stopping level of the second flow-through grooves 600 can be lower than that of the first flow-through grooves 500.

[0130] In addition, the ice-making tray 1 can further include through grooves 700. The through grooves 700 can be provided between the ice cell assembly 300 and the outer wall 400 so that adjacent cells of the ice cell assembly 300 are in communication in the direction of the rotation axis of the ice-making tray 1, i.e., in the first direction X1-X2 shown in FIG. 14, and the highest water-stopping level of the through grooves 700 can be lower than that of the second flow-through grooves 600.

[0131] In one example of the present application, the ice cube assembly 300 can include more ice cubes in addition to the first ice cube 300b and the second ice cube 300c, as needed. Referring to FIGS. 14 to 19, the ice cube assembly 300 can further include a third ice cube 300d and a fourth ice cube 300e, as one example according to the present application.

[0132] The third ice cube 300d can be connected to the first ice cube 300b through the through groove 700, and the third ice cube 300d is located on one side of the first ice cube 300b along the direction of the rotation axis of the ice cube tray 1, i.e., the first direction X1-X2 shown in FIG. 14, and is located on the same side of the first partition 300a as the first ice cube 300b.

[0133] The fourth ice cube 300e can be connected to the second ice cube 300c through the through groove 700, and the fourth ice cube 300e is located on one side of the second ice cube 300c along the direction of the rotation axis of the ice cube tray 1, i.e., the first direction shown in FIG. 14, and is located on the same side of the first partition 300a as the second ice cube 300c. In the case where the ice cube tray 1 is rotated by a specified angle, the ice-making water 200A located in the third ice cube 300d can overflow the side wall of the third ice cube 300d and enter the fourth ice cube 300e.

[0134] After the ice-making water 200A is injected into the first ice cube 300b, the ice-making water 200A can flow to the third ice cube 300d through the through groove 700 and be stored in the third ice cube 300d. In the first direction X1-X2 shown in FIG. 14, the third ice cube 300d can be arranged on both sides of the first ice cube 300b, so that the ice-making water 200A can be evenly spread to both sides after flowing out of the first ice cube 300b.

[0135] When the ice-making water 200A accumulates in the third ice cube 300d to reach the highest water level of the third ice cube 300d, i.e., the height of the ice-making water 200A in the third ice cube 300d reaches the maximum height of the side wall of the third ice cube 300d, the ice-making water 200A can enter the fourth ice cube 300e from the third ice cube 300d and accumulate in the fourth ice cube 300e. Also, in the case where the ice cube tray 1 is rotated by a specified angle, the ice-making water 200A located in the third ice cube 300d can enter the fourth ice cube 300e in the same way as the ice-making water 200A enters the second ice cube 300c from the first ice cube 300b, and in the case where the ice cube tray 1 is returned to the horizontal position, part of the ice-making water 200A is left in the fourth ice cube 300e, so that the third ice cube 300d and the fourth ice cube 300e can be relatively evenly distributed with the ice-making water 200A.

[0136] It can be understood that the shapes of the third and fourth compartments 300d and 300e can be the same as or different from those of the first and second compartments 300b and 300c. According to the ice-making requirements of the user, the third and fourth compartments 300d and 300e can be adaptively configured to have a shape contour of the compartments, so as to prepare ice cubes with a desired shape.

[0137] Referring to FIGS. 14 to 19, as an example according to the present application, the number of the third compartments 300d is plural. The plural third compartments 300d are arranged in sequence in the direction of the rotation axis of the ice-making tray 1, i.e., the first direction X1-X2 as shown in FIG. 14. Like the arrangement layout of the first compartments 300b, the third compartments 300d can also be configured to have a specific number of rows and a specific number of columns according to the size of the space in which the ice-making tray 1 is arranged, so that the arrangement of the plural third compartments 300d can be adapted to the space in which the ice-making tray 1 is arranged. Corresponding to the third compartments 300d, according to the injection amount of the ice-making water 200A and the specification of the ice-making tray 1, the number of the fourth compartments 300e can also be plural, and the plural fourth compartments 300e are arranged in sequence in the direction of the rotation axis of the ice-making tray 1, i.e., the first direction X1-X2 as shown in FIG. 14, which is not shown here.

[0138] By setting the first flow-through groove 500, the second flow-through groove 600, and the through groove 700, a plurality of structures similar to the water retaining dam can be formed between the plurality of first squares 300b, and the water retaining heights of these structures are different. In this way, when the ice-making water 200A is injected into the first squares 300b, taking the injection position shown in FIG. 23 as an example, the ice-making water 200A is first injected into the fifth square 12 shown in FIG. 23, and the water level height of the ice-making water 200A in the fifth square 12 is higher than the highest water retaining level of the second flow-through groove 600. After that, the ice-making water 200A flows over the second flow-through groove 600 and enters the sixth square 13 shown in FIG. 23. When the water level height of the ice-making water 200A in the sixth square 13 is higher than the highest water retaining level of the through groove 700, the ice-making water 200A immediately flows into the through groove 700 and flows along the through groove 700 to the seventh square 14 shown in FIG. 23. Then, when the water level height of the ice-making water 200A in the seventh square 14 is higher than the highest water retaining level of the second flow-through groove 600, the ice-making water 200A enters the eighth square 15 shown in FIG. 23 from the second flow-through groove 600 of the seventh square 14. Furthermore, as the ice-making water 200A is further injected, the water levels in the fifth square 12, the sixth square 13, the seventh square 14, and the eighth square 15 exceed the highest water retaining level of the first flow-through groove 500, so that the ice-making water 200A flows in the fifth square 12, the sixth square 13, the seventh square 14, and the eighth square 15, and finally the fifth square 12, the sixth square 13, the seventh square 14, and the eighth square 15 can maintain the same water level height.

[0139] In other examples, the fifth square 12 can not be provided with the second flow-through groove 600, so that the ice-making water 200A is first stored in the fifth square 12. Furthermore, when the water level height of the ice-making water 200A in the fifth square 12 exceeds the highest water retaining level of the first flow-through groove 500, the ice-making water 200A can flow from the fifth square 12 to the eighth square 15, so that the ice-making water 200A can also flow in the fifth square 12, the sixth square 13, the seventh square 14, and the eighth square 15. Alternatively, the seventh square 14 can not be provided with the second flow-through groove 600, so that the ice-making water 200A is first stored in the fifth square 12, the sixth square 13, and the seventh square 14, and when the water level height of the ice-making water 200A in the fifth square 12 exceeds the highest water retaining level of the first flow-through groove 500, the ice-making water 200A flows from the fifth square 12 to the eighth square 15. In this way, the ice-making water 200A can also flow in the fifth square 12, the sixth square 13, the seventh square 14, and the eighth square 15.

[0140] It can be understood that, in the case that the number of the second grids 300c is multiple, the second grids 300c can adopt the communication mode of the aforementioned multiple first grids 300b, so that the multiple second grids 300c are communicated through the first flow-through grooves 500, the second flow-through grooves 600 and the through grooves 700. In this way, after the ice-making water 200A enters the second grids 300c from the first grids 300b, the ice-making water 200A can flow in the multiple second grids 300c, so that the ice-making water 200A can be evenly distributed between the multiple second grids 300c. The principle of the ice-making water 200A flowing between the multiple second grids 300c is the same as that of the ice-making water 200A flowing between the multiple first grids 300b, which will not be described again.

[0141] Referring to FIGS. 14 to 19, as an example according to the present application, the third grids 300d can be provided with the second flow-through grooves 600. The second flow-through grooves 600 can communicate two adjacent third grids 300d. Also, the highest water retaining level of the second flow-through grooves 600 can be lower than the highest water retaining level of the first flow-through grooves 500 and lower than the partial highest water retaining level between the third grids 300d and the fourth grids 300e, so that the ice-making water 200A can flow between the multiple third grids 300d, thereby enabling the ice-making water 200A to fill the multiple third grids 300d when entering the third grids 300d. In an example of the present application, in the case that the number of the fourth grids 300e is multiple, the fourth grids 300e can also be provided with the second flow-through grooves 600, which communicate two adjacent fourth grids 300e by using the second flow-through grooves 600. The principle of the second flow-through grooves 600 provided in the third grids 300d is the same, which will not be described again.

[0142] Referring to FIGS. 14 to 19, as an example according to the present application, the third grids 300d can be provided with the second isolation portions 800. The extending direction of the second isolation portions 800 intersects with the direction of the rotation axis of the ice-making grid 1, i.e. the first direction X1-X2 shown in FIG. 14. In an example of the present application, the second isolation portions 800 can extend along the second direction Y1-Y2 and can protrude from the top of the third grids 300d. Also, the highest water retaining level of the second isolation portions 800 can be higher than the highest water retaining level of the second flow-through grooves 600.

[0143] By setting the second isolation part 800, when the ice-making water 200A is diverted from the first square 300b to the third square 300d, in the ice-making tray 1 shown in FIG. 14 and FIG. 15, because the second isolation part 800 protrudes from the top of the third square 300d, the highest water retaining level of the second isolation part 800 can be higher than the highest water retaining level of the third square 300d, the ice-making water 200A will flow along the second direction Y1-Y2 as shown in FIG. 14, filling each row of the third square 300d arranged along the first direction X1-X2. And, after the ice-making water 200A fills each row of the third square 300d, it can overflow the side wall of the corresponding third square 300d and enter the fourth square 300e. During the flow of the ice-making water 200A, the second isolation part 800 cooperates with the through groove 700 to form multiple water flow paths in the ice-making tray 1 that do not interfere with each other, so that the ice-making water 200A can flow more smoothly and is less likely to produce turbulent flow, thereby allowing the ice-making water 200A to be better distributed to each square.

[0144] It can be understood that the structure of the ice-making tray 1 can be diverse. In addition to the ice-making tray 1 shown in FIG. 14, in other examples, the ice-making tray 1 can also adopt a circular, irregular, or other structure. And, the first isolation part 300a can not be provided on the side wall of the square. In other examples, the first isolation part 300a can also extend from the bottom of a certain square or certain squares towards the second opening 1000 until it protrudes from the top of the ice tray assembly 300.

[0145] As another example of the present application, referring to FIG. 24, the ice-making tray 1 can include an ice tray assembly 300, an outer wall 400, and a first isolation part 300a. The ice tray assembly 300 can include a plurality of squares. The plurality of squares are used to contain ice-making water 200A. The outer wall 400 is arranged around the outer periphery of the ice tray assembly 300. And, the outer wall 400 can be arranged to be able to keep the ice-making water 200A in the ice-making tray 1 when the ice-making tray 1 is rotated by a specified angle. The first isolation part 300a can divide the ice-making tray 1 into a first area 9 and a second area 10. And, the first isolation part 300a can be arranged to be able to fill the squares located in the first area 9 with ice-making water 200A when the ice-making water 200A is injected into the first area 9, and to be able to overflow the first isolation part 300a and enter the squares located in the second area 10 with ice-making water 200A when the ice-making tray 1 is rotated by a specified angle.

[0146] It can be understood that the first area 9 and the second area 10 are also applicable to the ice-making tray 1 of the foregoing examples. Referring to FIG. 22, the area where the first square 300b is located can be regarded as the first area 9. The area where the second square 300c is located can be regarded as the second area 10. The same as the first square 300b and the second square 300c is that the first area 9 and the second area 10 can also be flexibly arranged. In the ice-making tray 1 as shown in FIG. 24, the first area 9 is located at the Y1 side of the first isolation part 300a, that is, the left side of the first isolation part 300a, and the second area 10 is located at the Y2 side of the first isolation part 300a, that is, the right side of the first isolation part 300a. In other embodiments, the first area 9 can also be located at the right side of the first isolation part 300a, and the second area 10 is located at the left side of the first isolation part 300a, so that the first area 9 and the second area 10 are separated by the first isolation part 300a, and the first area 9 and the second area 10 are respectively located at the two sides of the first isolation part 300a. When the ice-making water 200A is injected from the outside of the ice-making tray 1 to the inside of the ice-making tray 1, the area corresponding to the area where the injection point is located is the first area 9, and the area corresponding to the first area 9 and separated from the first isolation part 300a is the second area 10.

[0147] The ice-making tray 1 as shown in FIG. 24 can also achieve the functions and technical effects that the ice-making tray 1 of the foregoing examples can achieve by the arrangement of the first isolation part 300a, so when the ice-making tray 1 as shown in FIG. 24 is arranged in the refrigerator 100, the refrigerator 100 also has the advantages that the refrigerator of the foregoing examples can achieve, which will not be repeated here.

[0148] In summary, the refrigerator 100 according to the present application divides the ice cube assembly 300 into the first square 300b and the second square 300c by the first partition 300a, and the first partition 300a is arranged at the top of the ice cube assembly 300, so that the first partition 300a has a water retaining level higher than the first square 300b and the second square 300c. In this way, when the ice-making water 200A is injected into the first square 300b, the ice-making water 200A can first fill the space of the first square 300b, and then, when the amount of the ice-making water 200A is sufficient, the ice-making water 200A overflows the first partition 300a and enters the second square 300c from the first square 300b, so that the amount of the ice-making water 200A in the first square 300b can be ensured. Moreover, when the ice cube tray 1 is rotated by a specified angle, the ice-making water 200A is retained in the ice cube tray 1 by the outer wall 400, so that the ice-making water 200A cannot leak out of the ice cube tray 1, and the ice-making water 200A overflows the first partition 300a and enters the second square 300c from the first square 300b, so that even when the amount of the ice-making water 200A is insufficient, the ice-making water 200A can be stored in the first square 300b and the second square 300c by the rotation of the ice cube tray 1. Moreover, when the ice cube tray 1 is reset, under the action of the gravity of the ice-making water 200A and because the first partition 300a has a water retaining level higher than the first square 300b and the second square 300c, part of the ice-making water 200A is blocked by the first partition 300a and retained in the second square 300c, and the other part of the ice-making water 200A returns to the first square 300b, so that the ice-making water 200A can be more evenly distributed in the first square 300b and the second square 300c, and the ice-making water 200A cannot be adhered to form large ice cubes in the first square 300b or the second square 300c, so that the problem of the ice cubes in the ice cube tray 1 having different sizes can be avoided.

[0149] Moreover, the refrigerator 100 according to the present application expands the volume of the ice cube assembly 300 by arranging the third square 300d and the fourth square 300e in the ice cube tray 1, and the third square 300d and the adjacent third square 300d are communicated by the second flow-through groove 600, the fourth square 300e and the adjacent fourth square 300e are communicated by the second flow-through groove 600, and the ice cube assembly 300 is communicated in the direction of the rotation axis of the ice cube tray 1, i.e., the first direction X1-X2 shown in FIG. 14, by the through groove 700, so that the third square 300d and the fourth square 300e can share the ice-making water 200A with the first square 300b and the second square 300c, and the ice-making water 200A can be more evenly distributed in the first square 300b, the second square 300c, the third square 300d and the fourth square 300e.

[0150] To further solve the problem of ice cubes of different sizes and easy to stick together when ice is made by using an open ice tray in the prior art, and to enable the water injection pipe to inject ice-making water into the ice tray more uniformly, according to some embodiments of the present application, a kind of ice-making assembly 104 is also provided as shown in FIGS. 25-33.

[0151] Referring to FIGS. 25-33, the ice-making assembly 104 includes an ice tray 1 and a water injection pipe 2, wherein the ice tray 1 has a plurality of squares 1a, the top of each of the plurality of squares 1a has a third opening 10a arranged in the same direction, and a water passing groove is arranged between each of the adjacent two squares 1a. The water passing groove can be a flow-through groove or a through groove as described above for the passage of ice-making water.

[0152] It can be understood that the ice tray 1 can be configured according to the user's ice-making requirements, for example, the water passing groove can be arranged only between part of the squares 1a, so that the ice-making water flows along the specified path in the ice tray 1, or a plurality of squares 1a can be configured according to the amount of ice making at a time, and arranged in a rectangular array. The ice tray 1 of the ice-making assembly 104 as described in FIGS. 25-33 can have various configurations as described above, and can be arranged in the refrigeration chamber 103 of the refrigerator 100 as shown in FIGS. 1 and 12. Therefore, regarding the structure of the ice tray 1, please refer to the relevant description as described above with reference to FIGS. 1-24, which will not be described in detail here. The water injection pipe 2 can be arranged above the ice tray 1. And the water injection pipe 2 can be connected to the water system of the refrigerator 100, which can draw ice-making water from the water system of the refrigerator 100 and inject it into the ice tray 1. Referring to FIGS. 25-33, according to the present application, the water injection pipe 2 can include an input section 2000a and a water injection section 2000b. The input section 2000a can be used to connect to the water system of the refrigerator 100 to introduce ice-making water and make the ice-making water flow along the length direction of the water injection pipe 2. The water injection section 2000b can be connected to the input section 2000a. And the water injection section 2000b can be arranged at the tail of the input section 2000a along the length direction of the water injection pipe 2, so that the ice-making water can enter the water injection section 2000b in the flow direction.

[0153] The water injection section 2000b can be provided with a plurality of water injection holes 22b arranged towards the third opening 10a. And the diameter of the water injection hole 22b is smaller than the inner diameter of the input section 2000a of the water injection pipe 2. And a plurality of water injection holes 22b can be arranged in sequence on the flow path of the ice-making water along the flow direction of the ice-making water. And a plurality of water injection holes 22b can be arranged on the same plane, for example, on the same horizontal plane, on the pipe wall of the water injection section 2000b.

[0154] The ice-making water flows along the length direction of the water injection pipe 2 after entering the water injection pipe 2 from the input section 2000a, and enters the water injection section 2000b from the input section 2000a. Since the diameter of the water injection hole 22b is smaller than the inner diameter of the input section 2000a of the water injection pipe 2, the ice-making water will not flow out from the first water injection hole 22b near the tail of the input section 2000a, but will naturally flow along the length direction of the water injection pipe 2, i.e. the flow direction of the ice-making water, to the tail of the water injection section 2000b. In this way, the ice-making water will flow through all the water injection holes 22b in the water injection section 2000b and flow out from each water injection hole 22b, and fall into the ice-making grid 1.

[0155] It can be understood that, since the water injection holes 22b are arranged on the flow path of the ice-making water, the ice-making water can spread and cover all the water injection holes 22b when the ice-making water flows in the water injection section 2000b. Since the plurality of water injection holes 22b are arranged on the same horizontal plane, for example, based on the flowability of the liquid and the action of gravity, the ice-making water will not concentrate and gather at a certain water injection hole 22b, but will be dispersed to each water injection hole 22b, so that the ice-making water can flow out from the plurality of water injection holes 22b relatively uniformly, and form a plurality of water falling points in the ice-making grid 1. In this way, the ice-making grid 1 can have a larger water falling point area, and the ice-making water can flow and spread from different water falling point areas to other cells 1a around the corresponding water falling point area, so that the flow distance of the ice-making water flowing and spreading to all the cells 1a is shortened, thereby reducing the influence of the surface tension of the liquid on the flow and spread of the ice-making water to all the cells 1a, and making the water storage in each cell 1a in the ice-making grid 1 more uniform.

[0156] It should be noted that, in the interior of the water injection pipe 2, the structure of the plurality of water injection holes 22b arranged on the same horizontal plane is various, for example, the area where the plurality of water injection holes 22b are arranged can be a flat plane, or a flow guide structure or a flow distribution structure can be arranged between adjacent water injection holes 22b. The structure of the area where the water injection holes 22b are arranged can be configured according to the parameters of the ice-making assembly 104.

[0157] As described above, the ice-making assembly 104 can be arranged in the refrigeration chamber 103 of the refrigerator 100 to prepare ice blocks from ice-making water. Referring to FIGS. 12 and 25, 28 and 29, the ice-making assembly 104 can include an ice-making grid 1 and a water injection pipe 2. The ice-making grid 1 has a plurality of cells 1a, the top of each of the plurality of cells 1a has a third opening 10a arranged in the same direction, and all the cells 1a are provided with a water passing groove. The water passing groove can be a flow-through groove or a through groove as described above, for the ice-making water to pass through.

[0158] When the refrigerator 100 includes the ice making assembly 104 as shown in FIGS. 25, 28 and 29, the water injection pipe 2 can be disposed above the ice making tray 1. Also, the water injection pipe 2 can be connected to the water line system of the refrigerator 100, which can lead the ice making water from the water line system of the refrigerator 100 and inject the ice making water into the ice making tray 1. Also, the water injection pipe 2 includes an input section 2000a and a water injection section 2000b.

[0159] The input section 2000a can be used to connect with the water line system of the refrigerator 100 to lead the ice making water and flow the ice making water along the length direction of the water injection pipe 2. The water injection section 2000b can be connected to the input section 2000a. Also, the water injection section 2000b can be disposed at the tail of the input section 2000a along the length direction of the water injection pipe 2 to enable the ice making water to enter the water injection section 2000b in the flow direction. Also, the water injection section 2000b can be provided with a water injection surface 24b located on the flow path of the ice making water. The water injection surface 24b can be a horizontal surface extending along the flow direction of the ice making water. Also, the water injection surface 24b can be provided with a plurality of water injection holes 22b arranged in sequence and at intervals. The water injection holes 22b can have a hole diameter smaller than the inner diameter of the input section 2000a of the water injection pipe 2.

[0160] It can be understood that when the refrigerator 100 includes the ice making assembly 104 as shown in FIGS. 25, 28 and 29, the refrigerator 100 can be provided with a plurality of water injection holes 22b arranged on the same horizontal surface, for example, so that the refrigerator 100 can achieve the effect of enabling the water storage in each ice cube compartment 1a of the ice making tray 1 to be more uniform.

[0161] It can be understood that the hole area size of each water injection hole 22b can affect the flow of the ice making water at each water injection hole 22b. If the hole area of the water injection hole 22b close to the input section 2000a is too large, the ice making water can flow out of these water injection holes 22b in the case of insufficient flow of the ice making water, resulting in insufficient flow of the water injection holes 22b away from the input section 2000a. Therefore, the ice making water can be uniformly discharged from each water injection hole 22b by limiting the hole area size of the water injection hole 22b.

[0162] As an example according to the present application, referring to FIGS. 28-29, the hole areas of the plurality of water injection holes 22b are equal, and the sum of the hole areas of the plurality of water injection holes 22b is less than the passage area of the cross section of the input section 2000a of the water injection pipe 2. In other embodiments of the present application, the passage area of the cross section can also be referred to as the hole area of the cross section. In this way, the hole area of a single water injection hole 22b is much smaller than the passage area of the cross section of the input section 2000a of the water injection pipe 2, and the flow rate of a single water injection hole 22b is much smaller than the flow rate in the water injection pipe 2, so that when the ice-making water flows from the input section 2000a to the injection section, the ice-making water can not be discharged from all the water injection holes 22b close to the input section 2000a, and thus the ice-making water can naturally flow in the flow direction to the tail of the injection section 2000b, thereby covering all the water injection holes 22b. Of course, in other examples, the sum of the hole areas of the plurality of water injection holes 22b can also be equal to the passage area of the cross section of the input section 2000a of the water injection pipe 2, so that the hole area of a single water injection hole 22b is much smaller than the passage area of the cross section of the input section 2000a of the water injection pipe 2, and the flow rate of a single water injection hole 22b is much smaller than the flow rate in the water injection pipe 2, so that the ice-making water can also naturally flow in the flow direction to the tail of the injection section 2000b, thereby covering all the water injection holes 22b.

[0163] In other examples, the hole area of the water injection hole 22b can also gradually increase in the flow direction of the ice-making water. That is, the hole area of the water injection hole 22b gradually increases from the input section 2000a to the injection section 2000b, so that the hole area of the water injection hole 22b close to the input section 2000a can be smaller than the hole area of the water injection hole 22b away from the input section 2000a. In this way, the flow rate of the water injection hole 22b close to the input section 2000a can be smaller than the flow rate of the water injection hole 22b away from the input section 2000a. In this case, in combination with the limitation on the area of the plurality of water injection holes 22b, for example, the sum of the hole areas of the plurality of water injection holes 22b can be less than or equal to the passage area of the cross section of the input section 2000a of the water injection pipe 2, and the flow rate of a single water injection hole 22b can be much smaller than the flow rate in the water injection pipe 2, so that the ice-making water can also flow in the flow direction to the tail of the injection section 2000b, thereby covering all the water injection holes 22b, which is not illustrated here.

[0164] Referring to FIGS. 25-26, in the ice-making tray 1 according to the present application, the plurality of square cells 1a can be arranged in a rectangular array, for example, forming a layout design of two columns and six rows. In other examples, the square cells 1a can also be configured as other multi-row and multi-column layout designs or other array layout designs according to the demand for single ice-making amount, such as three rows and four columns, four rows and two columns, or a circular array, etc.

[0165] Generally, the ice cube tray 1 can be horizontally placed in use, so that the ice-making water can be stably placed in each of the ice cube cells la, and the ice-making water can be prevented from spilling out of the ice cube cells la. In this way, the water injection section 2000b of the water injection pipe 2 can be arranged, for example, in parallel with the ice cube tray 1. In order to enable the ice-making water to form a plurality of dispersed water falling points in the ice cube tray 1, as an example according to the present application, the extending direction of the water injection section 2000b can not be parallel to the arrangement direction of the plurality of ice cube cells la of the ice cube tray 1, but can intersect the arrangement direction of the plurality of ice cube cells la, so that the ice cube cells la facing the water injection holes 22b are not on the same straight line along the arrangement direction, i.e., the water falling points formed based on the water injection holes 22b are not on the same row or the same column. When the ice-making water is injected into the ice cube tray 1 from each of the water injection holes 22b, the ice-making water can be dispersedly injected into the ice cube cells la of different vertical columns or different horizontal rows of the ice cube tray 1. Since the ice-making water is distributed in different areas of the ice cube tray 1, the ice-making water can more easily spread from these ice cube cells la to the remaining ice cube cells la, and the ice-making water can be prevented from accumulating in a row of ice cube cells la or a column of ice cube cells la to form a clumped ice block.

[0166] It can be understood that the dispersion rate of the ice-making water in the water injection section 2000b can affect the flow rate of each of the water injection holes 22b, especially the flow rate of the water injection holes 22b located at the tail of the water injection section 2000b. Since the plurality of water injection holes 22b can be arranged in the water injection section 2000b in the form of being arranged on the same horizontal plane, the flow dispersion of the ice-making water in the water injection section 2000b largely depends on the flowability of the ice-making water itself and the flow rate when entering the water injection section 2000b. Therefore, in order to accelerate the dispersion efficiency of the ice-making water in the water injection section 2000b, as an example according to the present application, referring to FIG. 27, the input section 2000a can include a first end 20a and a second end 21a. The first end 20a can be away from the water injection section 2000b, and the first end 20a can be the starting point of the ice-making water entering the water injection pipe 2. The second end 21a can be connected to the water injection section 2000b, and the second end 21a can be the terminal point of the ice-making water leaving the input section 2000a. Moreover, the input section 2000a can be inclined relative to the ice cube tray 1, so that the input section 2000a gradually approaches the ice cube tray 1 from the first end 20a to the second end 21a, so that when the ice-making water flows in the input section 2000a, the ice-making water can obtain a certain flow rate based on its own gravity, and then rush into the water injection section 2000b, so that the ice-making water can quickly spread to each of the water injection holes 22b in the water injection section 2000b.

[0167] To prevent the ice-making water from accumulating inside the water injection pipe 2, a water flow guiding structure can be arranged in the water injection section 2000b to cause the ice-making water to converge at the water injection holes 22b. Referring to FIGS. 28-33, as an example according to the present application, the water injection section 2000b can further include a water flow guiding surface 25b. The water flow guiding surface 25b can extend along the arrangement direction of the water injection holes 22b. Moreover, the water flow guiding surface 25b can be arranged to be able to guide the ice-making water to converge at the corresponding water injection hole 22b.

[0168] It can be understood that when the water injection pipe 2 adopts different structural designs, the water flow guiding surface 25b can adopt a corresponding design. For example, when the outer contour of the water injection section 2000b of the water injection pipe 2 is square, the bottom of the water injection section 2000b can be provided with an arrangement surface 23b. The arrangement surface 23b is a flat surface. The water injection holes 22b are all arranged at the bottom of the water injection pipe 2, and the plurality of water injection holes 22b are arranged on the arrangement surface 23b.

[0169] The water flow guiding surface 25b can be a flat surface and arranged at the bottom of the water injection pipe 2. Moreover, the water flow guiding surface 25b can be arranged on both sides of the arrangement surface 23b and arranged obliquely relative to the arrangement surface 23b. One end of each water flow guiding surface 25b can be connected to the corresponding side wall of the water injection pipe 2, and the other end can be connected to the arrangement surface 23b, so that the ice-making water converges at the water injection hole 22b.

[0170] After the ice-making water enters the water injection section 2000b, since the water injection holes 22b are sandwiched by the water flow guiding surfaces 25b on both sides, regardless of whether the amount of ice-making water is sufficient or insufficient, the ice-making water entering the water injection section 2000b can always converge in the area where the arrangement surface 23b is located, so that the ice-making water can always accumulate at the water injection holes 22b on the arrangement surface 23b, ensuring that the ice-making water can be discharged from the water injection holes 22b out of the water injection pipe 2.

[0171] Under the constraint of the water injection holes 22b, the discharge amount of the ice-making water can be different from the injection amount. The injection amount of the ice-making water input into the water injection section 2000b can be greater than the discharge amount of the ice-making water discharged from the water injection holes 22b. In this case, the pipe volume of the water injection section 2000b of the water injection pipe 2 can be expanded, so that more ice-making water can be stored in the water injection section 2000b of the water injection pipe 2. Referring to FIGS. 30-31, as an example according to the present application, the cross-sectional passage area of the input section 2000a of the water injection pipe 2 can be smaller than the cross-sectional passage area of the water injection section 2000b of the water injection pipe 2, and the input section 2000a and the water injection section 2000b can be coaxially arranged. Moreover, the plurality of water injection holes 22b can be arranged on the same straight line, and in the use state, the water injection holes 22b can be arranged at the central portion of the pipe wall of the water injection section 2000b and at the central bottom. For example, in the normal use state, the water injection holes 22b can be located at the lowest portion of the pipe wall of the water injection section 2000b.

[0172] Since the cross-sectional passage area of the input section 2000a of the water injection pipe 2 is smaller than the cross-sectional passage area of the water injection section 2000b of the water injection pipe 2, the pipe volume of the input section 2000a of the water injection pipe 2 is smaller than the pipe volume of the water injection section 2000b of the water injection pipe 2. In this way, the water injection section 2000b can accommodate more ice-making water, and since the water injection holes 22b are arranged at the central bottom of the pipe wall of the water injection section 2000b in the use state, the plurality of water injection holes 22b are arranged on the same straight line, which can ensure that the ice-making water can flow smoothly and in sufficient quantity to each water injection hole 22b, avoiding insufficient water flow of the water injection holes 22b at the tail of the water injection section 2000b.

[0173] In summary, according to the refrigerator 100 of the present application, by arranging the water injection pipe 2 of the ice-making assembly 104, the input section 2000a and the water injection section 2000b of the water injection pipe 2 are connected in the same direction along the flow direction of the ice-making water, so that the ice-making water can flow smoothly in the water injection pipe 2. Moreover, since the water injection pipe 2 of the present application can be configured with a plurality of water injection holes 22b facing the third openings 10a of the square ice trays 1a in the water injection section 2000b, and the hole diameter of these water injection holes 22b can be smaller than the inner diameter of the input section 2000a of the water injection pipe 2, and the flow area of the water injection holes 22b can be smaller than the flow area of the input section 2000a, therefore, after the ice-making water flows from the input section 2000a to the water injection section 2000b, the ice-making water will not be discharged from the first water injection hole 22b closest to the input section 2000a, but will flow towards the tail of the water injection section 2000b, so that the ice-making water can flow through all the water injection holes 22b of the water injection section 2000b and be injected into the ice-making tray 1 from the plurality of water injection holes 22b, so that the plurality of square ice trays 1a can simultaneously store ice-making water, thereby expanding the water falling point area in the ice-making tray 1. In this way, the ice-making water can flow and diffuse from different water falling point areas to other square ice trays 1a around each water falling point area, so that the flow distance of the ice-making water flowing and diffusing to all the square ice trays 1a can be shortened, thereby reducing the influence of the liquid surface tension on the flow and diffusion of the ice-making water to all the square ice trays 1a, so that the water storage capacity of each square ice tray 1a in the ice-making tray 1 can be more uniform.

[0174] Moreover, the water injection pipe 2 according to the present application is provided with the flow guide surface 25b, so that the flow guide surface 25b is used to guide the ice-making water to converge to each water injection hole 22b, avoid the ice-making water to accumulate in the water injection pipe 2, and make the ice-making water better to converge to each water injection hole 22b, so that the ice-making water can be discharged from the water injection hole 22b in time. In addition, the extension direction of the water injection section 2000b of the water injection pipe 2 according to the present application can not be parallel to the arrangement direction of the plurality of squares 1a of the ice-making tray 1, but intersect with the arrangement direction of the plurality of squares 1a, so that the square 1a facing the water injection hole 22b is not on the same straight line along the arrangement direction, so that the water injection hole 22b can be dispersedly arranged. After the ice-making water is injected into the ice-making tray 1, it can be more easily spread to all the squares 1a.

[0175] The technical features of the above-mentioned embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-mentioned embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0176] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
