Description

Technical Field

[0001] This invention relates to the field of refrigerator ice-making technology, specifically to a large-capacity ice-making device and a refrigerator. Background Technology

[0002] Recently, large refrigerators have incorporated ice makers for producing ice. These ice makers are designed to freeze a specific amount of water supplied to an ice tray by applying cold air, and then transfer the ice from the tray to an ice storage container for storage. In this ice maker, the ice tray is positioned with a freezing point below 0°C, for example, in the freezer compartment, so that the water is frozen by the cold air. Therefore, the area where the cold air first reaches begins to freeze, and this freezing progresses towards the center. For example, the surface of the water that first comes into contact with the surrounding cold air begins to freeze, forming an ice core. Once the ice core is formed, the freezing progresses towards the center of the water, eventually forming ice. In existing ice makers, the water tank is typically rotated to drain and de-ice the water during ice making, making it difficult to seal the water tank, leading to leaks. Furthermore, the rotating structure is complex and has a high failure rate. Existing ice makers are also too large, taking up valuable space within the refrigerator. Summary of the Invention

[0003] The purpose of this invention is to provide an ice-making device and refrigerator with a large ice-making capacity. The ice-making device has a simple and reliable structure, the water storage box does not need to be flipped, and it has good sealing performance. It can increase the ice-making capacity while reducing the size of the ice maker.

[0004] To achieve the above objectives, in one aspect, embodiments of the present invention provide a large-capacity ice-making device, the ice-making device comprising:

[0005] Two uprights are installed in the refrigerator's cold storage compartment, and the two uprights are arranged side by side;

[0006] An ice-making module, the two ends of which are connected to the tops of the two columns for making and removing ice;

[0007] A water storage box is movably disposed below the ice-making module and can supply water to the ice-making module by moving it closer to or further away from the ice-making module along the column;

[0008] A water inlet pipe is located above the ice-making module, and the outlet of the water inlet pipe can pass through the ice-making module to supply water to the water storage box when the water storage box rises to the upper position.

[0009] An ice guide cover is provided, with both ends rotatably connected to the middle of the column and linked with the water storage box. When the water storage box descends, the ice guide cover closes to cover the water storage box, so that the ice blocks will not fall into the water storage box and guide the ice blocks to fall to the bottom. When the water storage box rises, the ice storage box opens.

[0010] An ice storage box is located below the water storage box to hold ice blocks.

[0011] Optionally, the ice-making module includes:

[0012] An ice-making mold, the two ends of which are connected to the tops of the two pillars;

[0013] An ice-making evaporator is located on top of the ice-making mold to introduce cold refrigerant to cool the ice-making mold and make ice, or to introduce hot refrigerant to heat the ice-making mold.

[0014] Optionally, the ice-making module includes a heater disposed on top of the ice-making mold to heat the ice after the refrigerant is introduced into the ice-making evaporator to complete ice making, so that the ice cubes fall off.

[0015] Optionally, the ice-making device includes:

[0016] The bracket has two ends connected to the bottom ends of the two columns;

[0017] A rack is arranged parallel to the inner side of each column, with the bottom of the rack connected to the bracket and the top of the rack connected to the ice-making module. The inner walls at both ends of the water storage box have channels to accommodate the rack.

[0018] A drive shaft is located at the bottom of the water storage box and is rotatably connected to a support block at the bottom of the water storage box. The two ends of the drive shaft are provided with first gears, which mesh with the rack. The middle part of the drive shaft is provided with a second gear.

[0019] A motor is located at the bottom of the water storage box, and the motor shaft is connected to a third gear. The third gear meshes with the second gear on the transmission shaft to drive the second gear to rotate.

[0020] Optionally, the ice guide cover has arc-shaped connecting plates at both ends, and the outer side of the arc-shaped connecting plate has a first protrusion. The first protrusion is rotatably connected to the middle of the column. The upper oblique angle of the arc-shaped connecting plate has a groove. The outer side walls of both ends of the water storage box have second protrusions. When the water storage box descends, the second protrusion can be inserted into the groove to press the ice guide cover to flip and cover the opening of the water storage box. When the water storage box rises, the second protrusion can lift the groove so that the ice guide cover flips and opens the opening of the water storage box.

[0021] Optionally, the opening area of ​​the ice storage box is larger than the opening area of ​​the water storage box, so as to catch the ice blocks falling from the ice guide cover.

[0022] Optionally, the ice-making device includes an insulated housing, which is disposed around the ice-making module, water storage box, and ice storage box.

[0023] Optionally, the bottom of the ice mold can be in various shapes.

[0024] Optionally, the arc-shaped connecting plate is inclined at a certain angle to the ice guide cover.

[0025] On the other hand, the present invention also provides a refrigerator, which includes a refrigerator body and an ice-making device as described above.

[0026] Through the above technical solution, the present invention provides a large-capacity ice-making device and refrigerator. Two columns are arranged side-by-side inside the refrigerator's cold storage compartment, with the ice-making module positioned atop these columns for ice making and de-icing. A water storage box is located below the ice-making module, moving along the columns towards or away from the ice-making module. When the water storage box approaches and surrounds the ice-making module, a water inlet pipe above the ice-making module begins supplying water to the water storage box, allowing the ice-making module to make ice within the water storage box. After a certain amount of ice has been made, the water storage box detaches from the ice-making module, allowing ice to freeze onto the module. The ice-making module then begins de-icing, with the ice falling into the ice storage box via an ice guide cover, thus completing the ice removal process. Because the water storage box can move linearly up and down, its structure is simple and reliable, avoiding the problems associated with existing methods that use rotation to drain water and then de-ic, which lead to difficulties in sealing the water tank, leaks, complex rotating structures, and high failure rates.

[0050] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0051] Figure 1 This is an exploded schematic diagram of a large-capacity ice-making apparatus according to one embodiment of the present invention. Figure 2 This is a front view of a large-capacity ice-making apparatus according to one embodiment of the present invention. Figure 3 This is a schematic diagram of the installation of a large-capacity ice-making device according to an embodiment of the present invention. In this invention, the ice-making device may include: a column 1, an ice-making module 2, a water storage box 3, a water inlet pipe 4, an ice guide cover 5, and an ice storage box 6. In this application, there may be two columns 1, which can be installed in the refrigerator compartment, and the two columns 1 may be arranged side by side. Both ends of the ice-making module 2 can be connected to the tops of the two columns 1 for ice making and ice removal. The water storage box 3 can be movably installed below the ice-making module 2 and can move along the column 1 towards or away from the ice-making module 2, thereby supplying water to the ice-making module 2. A water inlet pipe 4 can be installed above the ice-making module 2. The outlet of the water inlet pipe 4 can pass through the ice-making module 2, thereby supplying water to the water storage box 3 when it rises to the upper position. The two ends of the ice guide cover 5 can be rotatably connected to the middle of the column 1 and can be linked with the water storage box 3. This allows the water storage box 3 to be closed and covered when it descends, preventing the ice block from falling into the water storage box 3 and guiding it to fall to the bottom. When the water storage box rises, the water storage box 3 can be opened.

[0052] In this application, when ice making is required, the water storage box 3 can rise along the column 1 and approach the ice-making module 2. For example... Figure 6As shown, when the water storage box 3 rises to the upper position, the ice-making module 2 can be inside the water storage box 3. The water storage box 3 can reach the ice-making module 2, and the water storage box 3 can stop moving upwards, then the water inlet pipe 4 can start to fill with water. After the water level in the water storage box 3 reaches a certain level, the water filling can stop. When the water level in the water storage box 3 reaches a certain level, the ice-making module 2 can start to make ice. The ice-making module 2 can have ice-making and ice-removing functions. When the ice-making module 2 is making ice, it can start to cool down. After the temperature reaches below zero degrees, the water around the ice-making module 2 can start to freeze and can adhere to the ice-making module 2. After ice making, the water storage box 3 can descend. The descent of the water storage box 3 can drive the linkage of the ice guide cover 5. When the water storage box 3 descends to the ice outlet position, the ice guide cover 5 can be driven to close the water storage box 3. While the ice guide cover 5 is covering the water storage box 3, the ice-making module 2 can begin to detach the ice. As the ice-making module 2 begins to detach, the ice adhering to it can begin to fall off. Because the ice guide cover 4 has already covered the opening of the water storage box 3, the falling ice will not fall into the water storage box 3, but will instead fall along the ice guide cover 5 into the ice storage box 6, thus completing the ice removal process. After the ice falls into the ice storage box 6, the water storage box 3 can continue to rise. Then, the ice guide cover 5, linked to the water storage box 3, can open the water storage box 3, allowing it to rise to the upper position. Then, the water inlet pipe 4 can begin to fill with water, continuing the next round of ice-making. This cycle repeats continuously, achieving an ice production capacity of over 10 kg per day, far exceeding the current ice production capacity of refrigerators. When different sizes of ice blocks need to be produced, the ice-making module 2 can adjust the ice-making time as needed, thereby adjusting the size of the ice blocks adhering to it.

[0053] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 6As shown, the ice-making module 2 may include an ice-making mold 20 and an ice-making evaporator 21. Both ends of the ice-making mold 20 can be connected to the top of the column 1. The ice-making evaporator 21 can be located on top of the ice-making mold 20. The ice-making evaporator 21 can introduce cold refrigerant to cool the ice-making mold 20 to make ice; after ice making is complete, hot refrigerant can be introduced to heat the ice-making mold 20. When ice making is needed, the water storage box 3 can rise to the upper position, at which point the water storage box 20 can reach the ice mold 20. The bottom of the ice mold 20 can be inside the water storage box 3, and then the water inlet pipe 4 can start to introduce water. When the water in the water storage box 3 submerges the bottom of the ice mold 20, the ice evaporator 21 can start to introduce refrigerant to cool the ice mold 20. The bottom of the ice mold 20 has a certain shape. After the temperature reaches below zero degrees Celsius, the water around the bottom of the ice mold 20 can start to freeze and adhere to the bottom of the ice mold 20. After the ice mold 20 starts making ice, the ice can be discharged before all the water in the water storage box 3 is frozen. At this time, the ice is only frozen on the surface of the bottom of the ice mold 20, and the surface of the bottom of the ice mold 20 is all solid ice. Therefore, the water in the water storage box 3 will not freeze into a single piece. When the size of the ice cubes needs to be adjusted, this can be achieved by adjusting the time when the ice-making evaporator 21 introduces the refrigerant. Whether to dispense ice immediately or wait a while when the water temperature in the water tank 3 is detected to be 0 degrees Celsius controls the size of the ice cubes. When the ice mold 20 dispenses ice, the water tank 3 descends. Since the water in the water tank 3 does not contact the ice mold 20, ice making will not continue. Then, the ice-making evaporator 21 can begin to introduce hot refrigerant, causing the ice mold 20 to heat up. When the temperature of the ice mold 20 is above zero degrees Celsius, the ice cubes at the bottom of the ice mold 20 can begin to fall off. Because the descending water tank 3 causes the ice guide 5 to cover the opening of the water tank 3, the ice cubes will not fall into the water tank 3 but will fall along the ice guide 5 into the ice storage box 6, thus completing the ice dispensing process.

[0054] In this invention, the ice-making evaporator 21 requires the introduction of different types of refrigerants to cool or heat up during ice making and de-icing. Prolonged alternating hot and cold cycles may damage the ice-making evaporator 21, affecting its cooling performance. Therefore, in one embodiment of this invention, as... Figure 1 and Figure 2As shown, the ice-making module 2 may also include a heater 22. The heater 22 can be positioned on top of the ice mold 20. After the ice-making evaporator 21 introduces cold refrigerant to cool the ice mold 20 and completes ice making, the ice-making evaporator 21 can stop introducing cold refrigerant, and the heater 22 can begin heating the ice mold 20. When the temperature of the ice mold 20 is above zero degrees Celsius, the ice can begin to detach, thus completing the de-icing process. Because of the presence of the heater 22, the ice-making evaporator 21 can participate only in the cooling process without heating, or it can introduce hot refrigerant after cooling is complete to heat the ice mold 20. When the ice-making evaporator 21 only participates in cooling the ice mold 20, while the heater 22 participates in heating the ice mold 20, the evaporator 21 can only introduce cold refrigerant, eliminating the need to frequently switch the type of refrigerant introduced into the ice-making evaporator 21, thus extending its service life.

[0055] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the ice-making device may include: a support 7, a rack 8, a drive shaft 10, and a motor 14. The two ends of the support 7 can be connected to the bottom ends of two columns 1. There can be two racks 8, each rack 8 can be located inside the corresponding column 1, the bottom of the rack 8 can be connected to the support 7, and the top of the rack 8 can be connected to the ice-making module 2. The inner walls of both ends of the water storage box 3 are provided with channels 9 to accommodate the racks 8. The two racks 8 can pass through the channels 9 at both ends of the water storage box 3, so that the water storage box 3 can only move along the racks 8. The drive shaft 10 can be located at the bottom of the water storage box 3. Support blocks 11 can be provided at both ends of the bottom of the water storage box 3. The drive shaft 10 can be rotatably connected to the support blocks 11. First gears 12 can be provided at both ends of the drive shaft 10, and the first gears 12 can mesh with the racks 8, so that when the first gears 12 rotate, they can move along the racks 8. A second gear 13 may be provided in the middle of the drive shaft 10. The motor 14 may be located at the bottom of the water storage box 3, and the shaft of the motor 14 may be connected to a third gear 15. The third gear 15 may mesh with the second gear 13 of the drive shaft 10, thereby driving the second gear 13 to rotate.

[0056] When the water storage box 3 needs to be moved, the motor 14 installed in the water storage box 3 can rotate. This drives the third gear 15 connected to the shaft of the motor 14 to rotate, and the second gear 13 meshing with the third gear 15 can also rotate. This allows the transmission shaft 10 to rotate, as the first gears 12 at both ends of the transmission shaft 10 can mesh with the rack 8, allowing the transmission shaft 10 to move along the rack 8. The motor 14 can rotate forward and reverse. When the water storage box 3 needs to move along the rack 8, the motor 14 can be controlled to rotate forward or reverse, allowing the water storage box 3 to move up or down. The water storage box 3 can be moved by the motor 14 at its bottom. Its structure is simple, its failure rate is low, and it eliminates the need to consider issues such as leakage. This ice-making device has a simple structure, small size, and occupies little space in the refrigerator, thus greatly increasing the usable volume of the refrigerator.

[0057] In one embodiment of the present invention, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, arc-shaped connecting plates 16 can be provided at both ends of the ice guide cover 5. A first protrusion 17 can be provided on the outer side of the arc-shaped connecting plate 16. The first protrusion 17 can be rotatably connected to the middle of the column 1. A groove 18 can be formed at the upper oblique angle of the arc-shaped connecting plate 16. A second protrusion 19 can be provided on the outer walls of both ends of the water storage box 3. Figure 5 As shown, when the water storage box 3 begins to descend, the second protrusion 19 can engage with the groove 18. The second protrusion 19 can then continue to descend, pressing down on the groove 18, causing the ice guide cover 5 to flip. As the ice guide cover 5 flips, it covers the opening of the water storage box 3, preventing ice from falling into the water storage box 3. When the ice guide cover 5 flips above the water storage box 3, it can be at a certain angle to the opening of the water storage box 3, allowing ice to continue moving along the ice guide cover 5 and into the ice storage box 6 when it falls onto it. After the ice is removed, the water storage box 3 can move upward under the drive of the motor 14. When the water storage box 3 moves upward, the second protrusion 19 of the water storage box 3 can push the upper side of the groove 18, so that the ice guide cover 5 can flip and open the opening of the water storage box 3. At this time, the ice guide cover 5 can be on the side of the water storage box 3. Then the water storage box 3 can continue to rise and the second protrusion 19 can disengage from the groove 18. After the groove 18 disengages from the second protrusion 19, the position of the groove 18 remains unchanged, and the opening of the groove 18 still faces the second protrusion 19. When the ice-making water storage box 3 descends, the second protrusion 19 at both ends of the water storage box 3 can still be inserted into the groove 18, and then the ice guide cover 5 is flipped. This cycle is repeated to complete the ice making and ice removal.

[0058] In one embodiment of the present invention, the opening area of ​​the ice storage box 6 can be larger than the opening area of ​​the water storage box 3. When the ice block falls from the top onto the ice guide 5, it can continue to fall along the ice guide 5 and fall from the side of the water storage box 3. Since the opening area of ​​the ice storage box 6 is larger than the opening area of ​​the water storage box 3, the ice block can fall into the ice storage box 6.

[0059] In one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the ice-making device may include an insulated housing 30. The insulated housing 30 can be disposed around the ice-making module 2, the water storage box 3, and the ice storage box 6. The insulated housing 30, together with other insulating materials, can surround the ice-making device, thereby keeping the internal temperature of the ice storage box 6 below zero degrees Celsius to prevent the ice inside from melting. The insulated housing 6, disposed around the ice storage box 6, can block the ice from falling when ice making is complete, preventing it from leaving the opening of the ice storage box 6 and ensuring it falls entirely into the ice storage box 6.

[0060] In one embodiment of the present invention, such as Figure 1 As shown, the bottom of the ice mold 20 can be in various shapes. The bottom of the ice mold 20 can be made into different shapes and sizes as needed, so that ice blocks of different specifications and shapes can be made, thereby increasing the ice production capacity while reducing the size of the ice maker.

[0061] In one embodiment of the present invention, the arc-shaped connecting plate 16 and the ice guide cover 5 can be at a certain angle. When the ice guide cover 5 is rotated to be above the water storage box 3, because the arc-shaped connecting plate 16 and the ice guide cover 5 are at a certain angle, the ice guide cover 5 is also tilted, which can better guide the ice blocks to fall, so that the ice blocks will not accumulate on the ice guide cover 5.

[0062] On the other hand, the present invention also provides a refrigerator. This refrigerator may include a refrigerator body and an ice-making device as described above.

[0063] Through the above technical solution, the present invention provides a large-capacity ice-making device and refrigerator. Two columns are arranged side-by-side inside the refrigerator's cold storage compartment, with the ice-making module positioned atop these columns for ice making and de-icing. A water storage box is located below the ice-making module. This water storage box can move along the columns towards or away from the ice-making module. When the water storage box approaches and surrounds the ice-making module, a water inlet pipe above the ice-making module begins supplying water to the water storage box, allowing the ice-making module to make ice within the water storage box. After ice has been made to a certain extent, the water storage box detaches from the ice-making module, allowing ice to freeze onto the module. The ice-making module then begins de-icing, with the ice falling into the ice storage box via an ice guide cover, thus completing the ice removal process. Because the water storage box can move linearly up and down, its structure is simple and reliable, avoiding the problems of existing methods that use rotation to drain water and then de-ic, which make sealing the water tank difficult, prone to leakage, and have complex rotating structures with high failure rates.
