Description

Technical Field

[0001] The present disclosure relates to the field of household appliances, and particularly to an ice making device, an ice making method of the ice making device, and a refrigerator. Background Art

[0002] With the continuous improvement of people's living standards, refrigerators have become necessities in people's lives. Refrigerators use refrigeration to maintain a low temperature inside, which can not only store food, but also make ice by setting an ice making device, greatly facilitating users' demand for ice cubes.

[0003] In the related art, usually a water injection device is provided inside the refrigerator, and water is injected into the ice cells of the ice tray through the water injection device to make ice in the ice cells. However, during the water injection process, there may be a situation where the water injection volume of some ice cells is insufficient, which in turn affects the quality of the ice cubes. Summary of the Invention

[0004] In view of this, the present disclosure provides an ice making device, an ice making method of the ice making device, and a refrigerator. The ice making device and the ice making method can make the water in the ice tray evenly distributed, ensure the uniformity of the ice cube size, and improve the ice making quality.

[0005] Specifically, the present disclosure is implemented through the following technical solutions.

[0006] According to a first aspect of an embodiment of the present disclosure, there is provided an ice making device, including a liquid injection member, a carrying component, and an ice tray. The carrying component is provided with a receiving cavity and a water injection port communicating with the receiving cavity. At least a part of the liquid injection member communicates with the receiving cavity through the water injection port. The ice tray is disposed in the receiving cavity and is rotatably connected to the carrying component. A plurality of liquid storage grooves are respectively provided at intervals along a first direction and a second direction of the ice tray. A diversion groove is provided on the inner side wall of the liquid storage groove, and the diversion groove communicates with adjacent liquid storage grooves along the first direction of the ice tray and adjacent liquid storage grooves located on the outermost side along the first direction of the ice tray. Among them, the ice tray includes a first rotating part and a second rotating part, and the first rotating part and the second rotating part are provided with liquid storage grooves; when the ice tray rotates, the first rotating part is located above the second rotating part. The liquid injection member can inject water into the liquid storage grooves located in the first rotating part through the water injection port.

[0007] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects.

[0008] When water is injected into the ice tray of the ice making device, the liquid injection component injects water into the liquid storage tank located in the first rotating part through the water injection port. At this time, the ice tray can rotate, so that the water flows into the liquid storage tank of the second rotating part through the diversion groove, and then the water is evenly distributed in the liquid storage tank. And the diversion groove is connected to the adjacent liquid storage tanks along the first direction of the ice tray and the adjacent liquid storage tanks located on the outermost side along the first direction of the ice tray. Each liquid storage tank is only provided with two diversion grooves, and water enters or exits the liquid storage tank through these two diversion grooves, so as to balance the water inflow and outflow of each liquid storage tank, and further make the water evenly distributed in the liquid storage tank. Ensure that the ice cubes are of uniform size, thereby improving the production quality of the ice cubes.

[0009] The technical solutions of the present disclosure will be further described below.

[0010] In one embodiment, the liquid injection component can inject water into the liquid storage tank located in the first rotating part and on the inner side along the first direction of the ice tray through the water injection port.

[0011] In one embodiment, the diversion groove includes a first side wall and a second side wall opposite to the first side wall, and the first side wall and the second side wall are respectively provided with a convex part.

[0012] In one embodiment, in the projection in the depth direction of the diversion groove, the middle part of the convex part is higher than both sides of the convex part.

[0013] In one embodiment, the depth of the diversion groove is L1, and the depth of the liquid storage tank is L2, where L1 / L2≥0.4.

[0014] In one embodiment, the ice tray is convexly provided with a limiting member, and the bearing assembly is provided with a limiting groove. The limiting member can be arranged in the limiting groove, and when the ice tray rotates, the limiting member moves along the limiting groove.

[0015] According to the second aspect of the embodiments of the present disclosure, an ice making method for an ice making device is also provided. This method is applied to the ice making device in any of the above embodiments. The ice making method includes:

[0016] Control the liquid injection component to inject water into the liquid storage tank located in the first rotating part. Among them, the water injection volume of the liquid injection component includes a first water injection volume and a second water injection volume.

[0017] During the process of the liquid injection component injecting water at the first water injection volume, control the ice tray to rotate by a first angle.

[0018] During the process of the liquid injection component injecting water at the second water injection volume, control the ice tray to rotate by a second angle.

[0019] Wherein, when the first water injection volume is greater than the second water injection volume, the first angle is less than the second angle.

[0020] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects.

[0021] When injecting water into the ice tray of the ice making device, control the liquid injection component to inject water into the liquid storage tank of the first rotating part. When the liquid injection component injects water with the first water injection volume, control the ice tray to rotate by a first angle. When the liquid injection component injects water with the second water injection volume, control the ice tray to rotate by a second angle. And when the first water injection volume is greater than the second water injection volume, the first angle is less than the second angle. Such a design can make the rotation angle of the ice tray smaller when the water injection volume is large, so as to avoid water overflowing when the ice tray rotates. When the water injection volume is small, the rotation angle of the ice tray is larger, so that the water in the ice tray can be more evenly distributed in each liquid storage tank. Ensure that the ice cubes are of uniform size and improve the quality of ice cube production.

[0022] The technical solutions of the present disclosure will be further described below.

[0023] In one of the embodiments, after controlling the ice tray to rotate by the first angle and the second angle, the ice making method further includes:

[0024] After the ice making rotates by the first angle, control the ice tray to stop moving for a first preset time period.

[0025] After the ice making rotates by the second angle, control the ice tray to stop moving for a second preset time period.

[0026] Wherein, when the first angle is less than the second angle, the first preset time period is less than the second preset time period.

[0027] Control the ice tray after liquid injection to make ice.

[0028] In one of the embodiments, the range of the first angle is 5° to 25°. The range of the second angle is 8° to 40°.

[0029] According to the third aspect of the embodiments of the present disclosure, there is also provided a refrigerator, including the ice making module in any of the above embodiments. Or the ice making method applying the ice making module in any of the above embodiments.

[0030] The refrigerator includes the ice making module in any of the above embodiments, or applies the ice making method of the ice making module in any of the above embodiments. It can improve the quality of ice cube production of the refrigerator.

[0031] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. Description of the Drawings

[0054] With the continuous improvement of people's living standards, refrigerators have become necessities in people's lives. Refrigerators use refrigeration to maintain a low temperature inside, which can not only preserve food, but also make ice by setting up an ice-making device, greatly facilitating users' demand for ice cubes. Currently, there are a wide variety of refrigerator types and brands, giving consumers a lot of choices. How to gain consumers' favor and enhance product competitiveness has become an increasingly important issue for refrigerator manufacturers.

[0055] In related technologies, usually a water injection device is provided inside the refrigerator, and water is injected into the ice compartments of the ice tray through the water injection device to make ice in the ice compartments.

[0056] R & D personnel found in the practice of related technologies that during the water injection process of the water injection device, some ice compartments have insufficient water injection volume, which in turn affects the quality of the ice cubes.

[0057] Based on this, the present disclosure provides an ice-making device, an ice-making method of the ice-making device, and a refrigerator. The ice-making device and the ice-making method can make the water in the ice tray evenly distributed, ensure that the ice cubes are of uniform size, and improve the quality of ice cube production.

[0058] As Figure 1 and Figure 2 shown, the present application provides a refrigerator 1, including a cabinet device 10, a compressor 20, a condenser 30, an evaporator 40, and an expansion valve 50. The cabinet device 10 includes a cabinet assembly 11, a freezer compartment 13, a refrigerating compartment 14, and a door assembly 12. The freezer compartment 13 and the refrigerating compartment 14 are respectively arranged inside the cabinet assembly 11. The door assembly 12 includes a first door 12a and a second door 12b. The first door 12a is rotatably connected to the cabinet assembly 11 to open or close the freezer compartment 13. The second door 12b is rotatably connected to the cabinet assembly 11 to open or close the freezer compartment 13. The compressor 20, the condenser 30, the evaporator 40, and the expansion valve 50 are respectively arranged in the cabinet assembly 11, and at least part of the evaporator 40 is arranged inside the freezer compartment 13.

[0059] Combined with Figure 3As shown, when the refrigerator 1 operates, the compressor 20 outputs high-temperature and high-pressure gaseous refrigerant, which is transported to the condenser 30. The high-temperature and high-pressure gaseous refrigerant is condensed into medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant undergoes expansion throttling through the expansion valve 50, further reducing the pressure and temperature of the refrigerant, and flowing out of the expansion valve 50 as low-temperature and low-pressure liquid refrigerant to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into gaseous refrigerant in the evaporator 40. At least part of the evaporator 40 is disposed in the freezing chamber 13, such that a large amount of heat in the freezing chamber 13 is absorbed during the evaporation process of the refrigerant, thereby reducing the temperature in the freezing chamber 13, facilitating the use of the freezing chamber 13 to freeze items, and realizing the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. Thus, the refrigerant continuously circulates in the refrigerant circuit to maintain the freezing environment (e.g., less than -1°C) of the freezing chamber 13.

[0060] See you later Figure 2 As shown, an air duct 15 is provided between the refrigerating chamber 14 and the freezing chamber 13, facilitating the transportation of part of the cold air in the freezing chamber 13 to the refrigerating chamber 14 through the air duct 15 to reduce or maintain the low-temperature environment (e.g., 2°C to 8°C) in the refrigerating chamber 14.

[0061] As Figure 2 As shown, in some embodiments, along the height direction of the refrigerator 1, the freezing chamber 13 is disposed below the refrigerating chamber 14. The refrigerator 1 further includes a first blower (not labeled) disposed on the cabinet assembly 11. The air inlet end or the air outlet end of the first blower is in communication with the air duct 15, for transporting part of the cold air in the freezing chamber 13 to the refrigerating chamber 14.

[0062] As Figure 2 As shown, the height direction of the refrigerator 1 is the Z-axis direction.

[0063] In some embodiments, the outer sidewall of the freezing chamber 13 is covered with a heat insulation layer (not shown), to separate the evaporator 40 from the compressor 20 and the condenser 30.

[0064] In some embodiments, the outer sidewall of the freezing chamber 13 is covered with a heat insulation layer (not shown).

[0065] In some embodiments, the refrigerator 1 further includes an air-cooled heat dissipation assembly (not shown) disposed on the cabinet assembly 11, and the air-cooled heat dissipation assembly can at least dissipate heat from the condenser 30.

[0066] In some embodiments, the cabinet assembly 11 further includes a fresh-keeping chamber disposed on the cabinet assembly 11. Along the height direction of the refrigerator 1, the fresh-keeping chamber is disposed between the refrigerating chamber 14 and the freezing chamber 13.

[0067] To meet the user's need for using ice cubes, as Figure 4As shown, in some embodiments, the refrigerator 1 further includes an ice-making device 60 for making ice. The ice-making device 60 includes an ice-making component 100 and a liquid-injecting component 200. The ice-making component 100 includes an ice tray 110 disposed in the freezing compartment 13. The liquid-injecting component 200 is used to inject the liquid required for making ice into the ice tray 110.

[0068] As Figure 4 shown, in some embodiments, the ice-making component 100 is installed in the freezing compartment 13, and the cold provided by the refrigeration system to the freezing compartment 13 is used to make water into ice. Among them, the refrigeration system of the refrigerator 1 can be a common compression refrigeration system, which provides cold to the freezing compartment 13 in the form of direct cooling and / or air cooling, for example, so that the freezing compartment 13 has a desired storage temperature. When using an air-cooled refrigeration system, the refrigeration system of the refrigerator 1 sends the refrigerated air flowing through the evaporator 40 into the freezing compartment 13 for refrigeration through a fan.

[0069] Since the ice-making device 60 consumes the cold in the freezing compartment 13 when making ice. In some embodiments, when the ice-making device 60 is making ice, the refrigeration system can increase the operating frequency of the compressor 20 and the rotational speed of the fan, or increase the opening of the throttle valve to enhance the refrigeration effect of the evaporator 40. In this way, the freezing effect of the food in the freezing compartment 13 is prevented from being affected when the ice-making device 60 is making ice.

[0070] It should be noted that Figure 4 the first door 12a of the refrigerator 1 shown is open and not shown, and the second door 12b is in the closed state.

[0071] Optionally, in some embodiments, the liquid-injecting component 200 includes a water-receiving assembly for communicating with an external liquid injection pipe 220.

[0072] As Figure 4 shown, in one example, the liquid-injecting component 200 includes a liquid storage container 210 and a liquid injection pipe 220. The liquid storage container 210 is disposed in the refrigerating compartment 14. One end of the liquid injection pipe 220 communicates with the liquid storage container 210, and the other end of the liquid injection pipe 220 is disposed above the ice tray 110 along the height direction of the refrigerator 1.

[0073] Optionally, the liquid-injecting component 200 further includes a switching valve (not shown), which is disposed in at least one of the liquid storage container 210 and the liquid injection pipe 220, and is used to open the liquid-injecting component 200 to inject liquid into the ice tray 110, or close the liquid-injecting component 200.

[0074] As Figure 4As shown, in some embodiments, the ice tray 110 can be rotatably arranged in the freezing chamber 13, and has a liquid receiving state and an ice pouring state. The ice making component 100 also includes a driving assembly 120 and an ice storage container 130. The driving assembly 120 is arranged in the freezing chamber 13, and is used to drive the ice tray 110 to switch between the liquid receiving state and the ice pouring state. Along the height direction of the refrigerator 1, the ice storage container 130 is arranged below the ice tray 110. In this way, the ice storage container 130 can receive the ice cubes poured from the ice tray 110.

[0075] It should be noted that the ice tray 110 and the driving assembly 120 can be directly or indirectly disposed in the freezing chamber 13 .

[0076] like Figure 4 As shown, in some embodiments, the ice-making component 100 further includes a bearing assembly 140, and the bearing assembly 140 is fixed to the freezing chamber 13. The ice tray 110 is rotatably disposed on the bearing assembly 140. The driving assembly 120 is disposed on the bearing assembly 140. In this way, the ice tray 110 and the driving assembly 120 are integrated by the bearing assembly 140, so that the ice-making component 100 can be modularly assembled in the freezing chamber 13, which is conducive to improving the assembly efficiency of the refrigerator 1.

[0077] like Figure 10 As shown, in some embodiments, the driving assembly 120 is provided with a clamping protrusion 121, and the ice tray 110 is provided with a clamping groove 116, and the driving assembly 120 and the ice tray 110 are connected to the clamping protrusion 121 through the clamping groove 116. So that the driving assembly 120 can drive the ice tray 110 to rotate relative to the bracket assembly. In this way, when the ice tray 110 of the ice making device 60 is filled with water, the ice tray 110 is driven to rotate by the driving assembly 120, and the water flows from the liquid storage tank 111 of the first rotating part 113 to the liquid storage tank 111 of the second rotating part 114 through the guide groove 112, so that the water is evenly distributed in the liquid storage tank 111.

[0078] It should be noted that there may be many specific implementations of the drive component 120, including but not limited to an electric motor, a motor, and the like.

[0079] In some embodiments, the protrusion 121 is a non-cylindrical body or a partial cylinder. Specifically, the shape of the protrusion 121 can be a polygonal column such as a triangular prism or a quadrangular prism, a non-circular column such as an elliptical column or a plum blossom column, a semi-cylindrical column, or a partial cylinder of a 2 / 3 cylinder. In this way, a detachable transmission connection between the protrusion 121 and the slot 116 can be achieved, thereby facilitating the disassembly and installation of the ice tray 110.

[0080] In some embodiments, the liquid storage container 210 is disposed on the second door 12b. Thus, the liquid storage container 210 is stored in the cold storage compartment 14 through the second door 12b, so that the user can easily take and place the liquid storage container 210. In some embodiments, ice water can also be provided to the user.

[0081] In order to facilitate the cleaning of the ice-making component 100, the ice-making component 100 is usually detachably connected to the refrigerator 1, and the ice tray 110 is detachably connected to the ice-making component 100, so as to facilitate the removal of the ice-making component 100 and the ice tray 110 for cleaning. However, when the ice tray 110 is detached and installed on the ice-making component 100, and the ice-making component 100 is installed on the refrigerator 1, there is a problem of incorrect position installation.

[0082] In order to avoid incorrect installation, in some embodiments, after the ice maker is started, it is first detected whether the started ice-making component 100 and the ice tray 110 are installed in place. When the position of the ice-making component 100 is incorrectly installed or the ice-making component 100 is not installed at the preset position of the refrigerator 1, it will be detected that the ice-making component 100 is not installed in place. When the ice tray 110 is incorrectly installed or the ice tray 110 is not installed at the specified position as required, it will also be detected that the ice tray 110 is not installed in place.

[0083] Specifically, detecting whether the ice-making component 100 and the ice tray 110 are installed in place can be performed by means such as Hall sensors and infrared sensors.

[0084] Before ice making, it is necessary to inject liquid into the ice tray 110 through the liquid injection pipe 220. Since there will inevitably be residual liquid in the liquid injection pipe 220, the liquid injection pipe 220 will freeze and block the liquid injection pipe 220. Therefore, in some embodiments, the liquid injection pipe 220 is provided with a heating device, which can be, for example, a heating wire wound around the liquid injection pipe 220. The heating device is controlled to perform a heating operation, and the heating device is continuously turned on for a first duration within a fixed cycle duration, and the first duration is less than the fixed cycle duration. For example, the cycle duration is 60 seconds, and the first duration is less than 60 seconds. Thereby preventing the liquid injection pipe 220 from freezing.

[0085] In some embodiments, the ice-making component 100 includes a carrying component 140 and an ice tray 110. The water injection component includes a water pump, a water valve, and a liquid injection pipe 220. The water source can use the liquid storage container 210 provided inside the refrigerator 1 or be supplied with water by a water pipe outside the refrigerator 1. And water is injected into the ice tray 110 through the liquid injection pipe 220, and the opening and closing of the water are controlled by the water pump and the water valve.

[0086] Such as Figures 5 to 9As shown, in some embodiments, the carrier assembly 140 is provided with a receiving cavity 141 and a water injection port 142 communicating with the receiving cavity 141. At least a part of the liquid injection member 200 communicates with the receiving cavity 141 through the water injection port 142. The ice tray 110 is disposed in the receiving cavity 141 and is rotatably connected to the carrier assembly 140. A plurality of liquid storage grooves 111 are respectively provided at intervals along the first direction and the second direction of the ice tray 110. The inner side wall of the liquid storage groove 111 is provided with a diversion groove 112, and the diversion groove 112 communicates with adjacent liquid storage grooves 111 along the first direction of the ice tray 110 and adjacent liquid storage grooves 111 located on the outermost side along the first direction of the ice tray 110. Wherein, the ice tray 110 includes a first rotating portion 113 and a second rotating portion 114. When the ice tray 110 rotates, the first rotating portion 113 is located above the second rotating portion 114. The liquid injection member 200 can inject water into the liquid storage groove 111 located in the first rotating portion 113 through the water injection port 142. Thus, when injecting water into the ice tray 110 of the ice making device 60, the liquid injection member 200 injects water into the liquid storage groove 111 located in the first rotating portion 113 through the water injection port 142. At this time, the ice tray 110 can rotate, so that the water flows into the liquid storage groove 111 of the second rotating portion 114 through the diversion groove 112, and further makes the water evenly distributed in the liquid storage groove 111. And the diversion groove 112 communicates with adjacent liquid storage grooves 111 along the first direction of the ice tray 110 and adjacent liquid storage grooves 111 located on the outermost side along the first direction of the ice tray 110. So that each liquid storage groove 111 is only provided with two diversion grooves 112, and the water enters or exits the liquid storage groove 111 through these two diversion grooves 112, thereby balancing the water inflow and outflow of each liquid storage groove 111, and further making the water evenly distributed in the liquid storage groove 111. Ensure that the ice cubes are of uniform size, thereby improving the production quality of the ice cubes. And by adjusting the water injection volume, ice cubes of different sizes can be prepared, and the ice cubes produced by the same ice tray 110 are of uniform size.

[0087] It should be noted that the carrier assembly 140 can play a role in protecting and preventing pollution to the ice tray 110.

[0088] It should be noted that as Figure 9 shown, the first direction of the ice tray 110 is the X direction shown in the figure, and the second direction of the ice tray 110 is the Y direction shown in the figure.

[0089] As Figure 7 shown, in some embodiments, the liquid injection member 200 is connected to the water injection port 142 through a liquid injection pipe 220, so as to communicate with the receiving cavity 141. Thus, the liquid injection member 200 injects water into the ice tray 110 disposed in the receiving cavity 141 through the liquid injection pipe 220.

[0090] As Figure 10As shown, in some embodiments, the driving assembly 120 is provided with a clamping projection 121, and the ice tray 110 is provided with a clamping groove 116. The driving assembly 120 and the ice tray 110 are drivingly connected through the clamping groove 116 and the clamping projection 121, so that the driving assembly 120 can drive the ice tray 110 to rotate relative to the bracket assembly. In this way, when the ice tray 110 of the ice making device 60 is filled with water, the ice tray 110 is driven to rotate by the driving assembly 120, and the water flows from the liquid storage tank 111 of the first rotating part 113 to the liquid storage tank 111 of the second rotating part 114 through the diversion groove 112, so that the water is evenly distributed in the liquid storage tank 111.

[0091] It should be noted that there are various specific implementation manners of the driving assembly 120, including but not limited to motors, motors, and the like.

[0092] In some embodiments, the clamping projection 121 is a non-cylindrical body or a partial cylinder. Specifically, the shape of the clamping projection 121 can be a polygonal column such as a triangular prism or a quadrangular prism, a non-circular column such as an elliptical cylinder or a plum blossom column, or a partial cylinder such as a semi-cylinder or a 2 / 3 cylinder. In this way, a detachable driving connection between the clamping projection 121 and the clamping groove 116 can be realized, so as to facilitate the disassembly and installation of the ice tray 110.

[0093] As Figure 6 shown, in some embodiments, the liquid injection component 200 can inject water into the liquid storage tank 111 located in the first rotating part 113 and on the inner side along the first direction of the ice tray 110 through the water injection port 142. In this way, by injecting water into the liquid storage tank 111 located in the first rotating part 113 and on the inner side along the first direction of the ice tray 110, during the process of filling the ice tray 110 with water, it is possible to avoid the ice tray 110 being heavy at one end and light at the other end due to water concentration at the end of the ice tray 110, thereby avoiding deformation of the ice tray 110 during the water injection process and causing water to overflow in the ice tray 110.

[0094] The R & D personnel found in the practice of the flow of water between the liquid storage tanks 111 that when water flows between the liquid storage tanks 111 through the diversion groove 112, the flow rate of water in the diversion groove 112 is slow due to the surface tension of water.

[0095] In order to reduce the surface tension of water in the diversion groove 112, as Figure 8 and Figure 9 shown, in some embodiments, the diversion groove 112 includes a first side wall and a second side wall opposite to the first side wall, and the first side wall and the second side wall are respectively provided with a raised portion 101. In this way, by providing the raised portions 101 on the side walls on both sides of the diversion groove 112, the raised portions 101 can reduce the surface tension of water in the diversion groove 112, facilitating the flow of water in the diversion groove 112. Thereby, the flow rate of water in each liquid storage tank 111 is increased, and the water injection efficiency is improved.

[0096] Further, in some embodiments, under the projection in the depth direction of the diversion groove 112, the middle part of the convex part 101 is higher than both sides of the convex part 101. In this way, by designing the middle part of the convex part 101 to be higher than both sides of the convex part 101, the surface tension of water can be further reduced and the flow rate of water can be further increased.

[0097] It should be noted that, as Figure 7 shown, the depth direction of the diversion groove 112 is the Z direction shown in the figure.

[0098] It can be understood that the specific structure of the convex part 101 can also be other shapes, as long as at least part of it protrudes from other parts.

[0099] As Figure 11 and Figure 12 shown, in some embodiments, the inner side wall of the diversion groove 112 is provided with an introduction groove 102. In this way, by providing the introduction groove 102 in the diversion groove 112, the surface tension of water can be further reduced and the flow rate of water can be further increased.

[0100] It should be noted that there are various specific implementation manners of the introduction groove 102, including but not limited to chamfering, rounding the inner side wall of the diversion groove 112, etc.

[0101] As Figure 13 and Figure 14 shown, in some embodiments, the depth of the diversion groove 112 is L1, and the depth of the liquid storage groove 111 is L2, where L1 / L2≥0.4. In this way, the depth L1 of the diversion groove 112 / the depth L2 of the liquid storage groove 111≥0.4, which can enable water to flow easily into the diversion groove 112 when the water injection amount of the liquid injection component 200 is small, facilitating the entry or discharge of water into or from the liquid storage groove 111 through the diversion groove 112, so that the water can be evenly distributed in the liquid storage groove 111. Ensure that the ice cubes are of uniform size, thereby improving the production quality of the ice cubes.

[0102] It should be noted that for the depth L1 of the diversion groove 112 / the depth L2 of the liquid storage groove 111≥0.4, for example, when the depth of the liquid storage groove 111 is 10 mm, the depth of the diversion groove 112 is greater than or equal to 4 mm.

[0103] Optionally, L1 / L2 can be greater than or equal to 0.4, 0.5, 0.6, etc.

[0104] As Figure 15As shown, in some embodiments, the ice tray 110 is provided with a protruding limiting member 115, and the loading assembly 140 is provided with a limiting groove 143. The limiting member 115 is disposed within the limiting groove 143, and when the ice tray 110 rotates, the limiting member 115 moves along the limiting groove 143. In this way, it is ensured that the ice tray 110 rotates along a preset path of the limiting groove 143 during rotation, thereby improving the reliability of the rotation of the ice tray 110.

[0105] Based on the above ice making device 60, the present disclosure further provides an ice making method for the ice making device 60, and this ice making method can be applied to the aforementioned ice making device 60. This ice making method includes:

[0106] Controlling the liquid injection component 200 to inject water into the liquid storage tank 111 located in the first rotating part 113. Among them, the water injection volume of the liquid injection component 200 includes a first water injection volume and a second water injection volume.

[0107] During the process of the liquid injection component 200 injecting water with the first water injection volume, controlling the ice tray 110 to rotate by a first angle.

[0108] During the process of the liquid injection component 200 injecting water with the second water injection volume, controlling the ice tray 110 to rotate by a second angle.

[0109] Among them, when the first water injection volume is greater than the second water injection volume, the first angle is less than the second angle.

[0110] In this way, when injecting water into the ice tray 110 of the ice making device 60, control the liquid injection component 200 to inject water into the liquid storage tank 111 located in the first rotating part 113. When the liquid injection component 200 injects water with the first water injection volume, control the ice tray 110 to rotate by the first angle. When the liquid injection component 200 injects water with the second water injection volume, control the ice tray 110 to rotate by the second angle. And when the first water injection volume is greater than the second water injection volume, the first angle is less than the second angle. Such a design can make the rotation angle of the ice tray 110 smaller when the water injection volume is large, thereby avoiding water overflow when the ice tray 110 rotates. When the water injection volume is small, the rotation angle of the ice tray 110 is larger, which is more convenient for the water in the ice tray 110 to be evenly distributed in each liquid storage tank 111. Ensure that the ice cubes are of uniform size and improve the quality of ice cube production.

[0111] In some embodiments, the range of the first angle is 5° - 25°. The range of the second angle is 8° - 40°.

[0112] Optionally, the range of the first angle is 8° - 15°. The range of the second angle is 10° - 35°.

[0113] Optionally, the first angle can be 8°, 9°, 10°, 12°, 14°, 15°. The second angle can be 10°, 15°, 20°, 25°, 30°, 35°.

[0114] As Figure 8 shown, in some embodiments, after controlling the ice tray 110 to rotate by the first angle and the second angle, the ice-making method further includes:

[0115] After the ice-making rotates by the first angle, control the ice tray 110 to stop moving for a first preset duration.

[0116] After the ice-making rotates by the second angle, control the ice tray 110 to stop moving for a second preset duration.

[0117] Wherein, when the first angle is less than the second angle, the first preset duration is less than the second preset duration.

[0118] Thus, after the ice tray 110 of the ice-making device 60 is filled with water and rotated by a certain angle, control the ice tray 110 to maintain at this angle for a period of time, so that the water can flow better to each liquid storage tank 111, and further make the water in the ice tray 110 evenly distributed in each liquid storage tank 111. Ensure that the ice cubes are of uniform size and improve the quality of ice cube production. And, according to the actual water injection volume, control the duration of the ice tray 110 stopping motion. For example, when the first water injection volume is greater than the second water injection volume, the first preset duration is less than the second preset duration. When the water injection volume is large, the water flow speed is faster when the ice tray 110 is tilted, so the tilting duration of the ice tray 110 is shorter to avoid water overflowing in the ice tray 110. When the water injection volume is small, the water flow speed is slower when the ice tray 110 is tilted, so the tilting duration of the ice tray 110 is longer, making the water flow evenly to each liquid storage tank 111 better.

[0119] Optionally, the range of the first preset duration is 1 s to 5 s, and the range of the second preset duration is 2 s to 8 s.

[0120] Optionally, the first preset duration can be 1 s, 2 s, 3 s, 4 s, 5 s. The second preset duration can be 2 s, 3 s, 5 s, 6 s, 8 s.

[0121] It should be noted that when selecting the best angle and duration, the R & D personnel have conducted experimental verification on different water injection volumes. Specifically, when the water injection volume is (6 - 10) g * the number of ice cubes in the ice grid, the rotation angle of the ice tray 110 is 10°, and the duration of stopping motion at this rotation angle is 1 s. At this time, the uniformity of the water in each liquid storage tank 111 is the best. When the water injection volume is (2 - 6) g * the number of ice cubes in the ice grid, the rotation angle of the ice tray 110 is 30°, and the duration of stopping motion at this rotation angle is 3 s. At this time, the uniformity of the water in each liquid storage tank 111 is the best.

[0122] In some embodiments, after the water injection is completed, the steps of rotating the ice tray 110 by an angle and stopping the movement for a preset duration can be repeated 2 to 3 times. In this way, the water in the liquid storage tank 111 is further evenly distributed, further ensuring that the ice cubes are of uniform size, thereby improving the quality of ice cube production.

[0123] It can be understood that the water injection volume of the liquid injection component 200 can be set through the refrigerator 1 according to the actual needs of the user.

[0124] Specifically, the refrigerator 1 can be connected to a control terminal such as a mobile phone, a tablet computer, or a dedicated terminal through a network or other data transmission means. The user realizes the control function of the refrigerator 1 through the control terminal. The control terminal interacts with the user by utilizing the human-computer interaction ability, for example, outputs a relevant control interface through the screen and receives the user's operations.

[0125] In some embodiments, the user can send an ice-making instruction to the refrigerator 1 through the control terminal. The user can directly customize the water injection volume or set the required ice cube size, and the refrigerator 1 then calculates the required water injection volume based on the size of the ice cubes. Thereby, the liquid injection component 200 is controlled to inject water into the ice-making device 60.

[0126] Furthermore, in some embodiments, the control terminal needs to obtain the control authority of the refrigerator 1, for example, by binding the user name, etc., to obtain the control authority of the refrigerator 1. The refrigerator 1 only responds to the instructions issued by the control terminal with control authority, improving data security.

[0127] In some other embodiments, the refrigerator 1 can also output an ice-making interface through its own display screen for the user to set the ice-making time and the ice-making amount, thereby sending an ice-making instruction to the refrigerator 1.

[0128] It should be noted that the above embodiments can be complementary to each other without conflict.
