[0032] This application provides a defrosting device and a refrigerator. The defrosting device and the refrigerator of this application will be described in detail below with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners may be combined with each other.

[0033] Figure 1 It is a schematic structural diagram of a refrigerator shown in an embodiment. Figure 2 is Figure 1 a half-sectional view of the refrigerator shown in A-A. In Figure 1 - Figure 2In the illustrated embodiment, the present application provides a refrigerator 1, which includes a cabinet device 80, a compressor 86, a condenser 87, an evaporator 88, and an expansion valve 89. The cabinet device 80 includes a cabinet assembly 81, a freezer compartment 83, a refrigerator compartment 84, and a door assembly 82. The freezer compartment 83 and the refrigerator compartment 84 are respectively arranged within the cabinet assembly 81. The door assembly 82 includes a first door 82a and a second door 82b. The first door 82a is rotatably connected to the cabinet assembly 81 to open or close the freezer compartment 83. The second door 82b is rotatably connected to the cabinet assembly 81 to open or close the freezer compartment 83. The compressor 86, the condenser 87, the evaporator 88, and the expansion valve 89 are respectively arranged within the cabinet assembly 81, and at least a part of the evaporator 88 is arranged within the freezer compartment 83.

[0034] Figure 3 is Figure 1 the refrigeration schematic diagram of the illustrated refrigerator. Combining Figure 3 as shown, when the refrigerator 1 operates, the compressor 86 outputs high-temperature and high-pressure gaseous refrigerant and transports it to the condenser 87, where the high-temperature and high-pressure gaseous refrigerant is condensed into medium-temperature and high-pressure refrigerant through the condenser 87. The medium-temperature and high-pressure refrigerant undergoes the expansion throttling effect of the expansion valve 89, causing the pressure and temperature of the refrigerant to further decrease, and flowing out of the expansion valve 89 as low-temperature and low-pressure liquid refrigerant to the evaporator 88. The low-temperature and low-pressure liquid refrigerant evaporates into gaseous refrigerant within the evaporator 88. And at least a part of the evaporator 88 is arranged within the freezer compartment 83, enabling the refrigerant to absorb a large amount of heat within the freezer compartment 83 during the evaporation process, thereby reducing the temperature within the freezer compartment 83, facilitating the use of the freezer compartment 83 to freeze items, and realizing the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 88 is replenished back to the compressor 86 to form a refrigerant circuit. In this way, the refrigerant continuously circulates within the refrigerant circuit to maintain the freezing environment (for example, less than -1°C) of the freezer compartment 83.

[0035] Refer back to Figure 2 as shown, there is an air duct 85 provided between the refrigerator compartment 84 and the freezer compartment 83, facilitating the transportation of a part of the cold air in the freezer compartment 83 to the refrigerator compartment 84 through the air duct 85 to reduce or maintain the low-temperature environment (for example, 2°C to 8°C) of the refrigerator compartment 84.

[0036] As Figure 2 shown, in some embodiments, along the height direction (Z-axis direction) of the refrigerator 1, the freezer compartment 83 is arranged below the refrigerator compartment 84. The refrigerator 1 further includes a first blower (not labeled) arranged on the cabinet assembly 81. The air inlet end or the air outlet end of the first blower is communicated with the air duct 85, and is used for transporting a part of the cold air in the freezer compartment 83 to the refrigerator compartment 84.

[0037] In some embodiments, the outer wall of the freezing compartment 83 is covered with a heat-insulating layer (not shown) to separate the evaporator 88 from the compressor 86 and the condenser 87. The refrigerator 1 further includes an air-cooled heat dissipation assembly (not shown) disposed in the cabinet assembly 81, and the air-cooled heat dissipation assembly can at least dissipate heat from the condenser 87.

[0038] In some embodiments, the cabinet assembly 81 further includes a fresh-keeping compartment disposed in the cabinet assembly 81. Along the height direction of the refrigerator 1, the fresh-keeping compartment is disposed between the refrigerating compartment 84 and the freezing compartment 83.

[0039] Further, to meet the user's need for using ice cubes, as Figure 4 shown, in some embodiments, the refrigerator 1 further includes an ice-making device 90 for making ice cubes. The ice-making device 90 includes an ice-making component 100 and a liquid-injecting component 200.

[0040] The ice-making component 100 includes a mounting shell 110, a driving assembly 120 mounted on the mounting shell 110, and an ice mold device 140 driven by the driving assembly 120. The output end of the driving assembly 120 is fixedly connected to the ice mold device 140, and the ice mold device 140 is rotatably connected to the mounting shell 110. The driving assembly 120 can drive the ice mold device 140 to switch between a liquid-receiving state and an ice-dumping state. Among them, the mounting shell 110 can be directly or indirectly disposed in the freezing compartment 83.

[0041] The ice-making component 100 further includes an ice storage container 130. Along the height direction of the refrigerator 1, the ice storage container 130 is disposed below the ice mold device 140. In this way, the ice storage container 130 can receive the ice cubes dumped by the ice mold device 140.

[0042] The liquid-injecting component 200 is used to inject the liquid required for making ice cubes into the ice mold device 140. 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 84. One end of the liquid injection pipe 220 is communicated with the liquid storage container 210, and along the height direction of the refrigerator 1, the other end of the liquid injection pipe 220 is disposed above the ice mold device 140.

[0043] Optionally, the liquid-injecting component 200 further includes a switching valve (not shown), and the switching valve is disposed in at least one of the liquid storage container 210 and the liquid injection pipe 220 for opening the liquid-injecting component 200 to inject liquid into the ice mold device 140 or closing the liquid-injecting component 200. In addition, in some embodiments, the liquid-injecting component 200 may further include a water receiving assembly for communicating with an external liquid injection pipe 220.

[0044] In some embodiments, Figure 4The first cabinet door 82a of the refrigerator shown is open and not shown, and the second cabinet door 82b is in a closed state. The liquid storage container 210 is provided on the second cabinet door 82b. In this way, the liquid storage container 210 is stored in the refrigerating chamber through the second cabinet door 82b, which is convenient for the user to take and place the liquid storage container 210. In some embodiments, ice water can also be provided for the user.

[0045] It should be noted that the installation shell 110 of the ice-making component 100 has a cavity, the driving assembly 120 is fixedly arranged in the cavity, and the ice mold device 140 is rotatably connected in the cavity. The cavity is provided with an air inlet and an air outlet so that the refrigeration system in the refrigerator 1 can cool the ice mold device 140 to form ice cubes. Moreover, the cavity formed by the installation shell 110 can also prevent the air or impurities with other odors in the cabinet device 80 from entering the ice mold device 140, so as to avoid affecting the taste and purity of the ice cubes.

[0046] Thus, in addition to the functions of freezing, refrigerating, and preserving food, the refrigerator 1 can also have functions such as making ice cubes and providing ice water for users, meeting people's usage requirements, and further enhancing the competitiveness of the refrigerator 1 product.

[0047] Figure 5 The figure shows a schematic structural view of an ice removal device 10 from one perspective according to an exemplary embodiment of the present application. Figure 6 As shown Figure 5 A schematic structural view of another perspective of the ice removal device 10 shown. In Figure 5 and Figure 6In the described embodiments, an ice removal device 10 provided by the present application is used in cooperation with the above-mentioned ice making device 90 to produce and demold ice cubes. The ice removal device 10 includes a housing 11, a first ice tray 12, a second ice tray 13, and a driving member 16. The first ice tray 12 and the second ice tray 13 are disposed inside the housing 11. The first ice tray 12 is provided with a plurality of first ice cells 14, and the second ice tray 13 is provided with a plurality of second ice cells 15. The volume of the second ice cells 15 is smaller than that of the first ice cells 14. The second ice tray 13 is disposed on the back of the first ice tray 12, and the openings of the first ice cells 14 and the second ice cells 15 face away from each other. The housing 11 in the present application is used to carry the first ice tray 12 and the second ice tray 13. The ice cells provided on the first ice tray 12 and the second ice tray 13 can be used for injecting water to make ice. By setting the volume of the second ice cells 15 to be smaller than that of the second ice cells 15, ice cubes of different volumes are made in the first ice cells 14 and the second ice cells 15, providing users with a variety of ice cube sizes to choose from, so as to enhance the user experience. By setting the openings of the first ice cells 14 and the second ice cells 15 to face away from each other, it effectively avoids simultaneous ice making in the first ice cells 14 and the second ice cells 15, preventing the ice sizes from being different and not meeting the user's selection. The driving member 16 of the present application includes a driving source 17 and a driving shaft 18. The driving source 17 is disposed on the side of the housing 11. The driving shaft 18 is connected to the driving source 17 and is also connected to the first ice tray 12 and the second ice tray 13. The driving member 16 is used to drive the first ice tray 12 and the second ice tray 13 to perform a flipping motion to switch the ice making and ice removal between the first ice cells 14 and the second ice cells 15. By providing the driving member 16, the driving source 17 drives the driving shaft 18 to rotate, and drives the first ice tray 12 and the second ice tray 13 connected to the driving shaft 18 to perform a flipping motion, so as to enable the first ice cells 14 or the second ice cells 15 to face the water injection surface for ice making. Users can select the flipping surface of the first ice cells 14 or the second ice cells 15 to face upward to determine the size of the ice cubes to be made, thereby meeting the user's requirements for ice cubes of different shapes and volumes and overcoming the problem of single ice cube size.

[0048] Figure 7 As shown in Figure 5 FIG. is a schematic structural diagram of the connection between the switching turntable 19 of the ice removal device 10 shown and the ice tray. In Figure 7In the illustrated embodiment, in order to better achieve the switching between the first ice tray 12 and the second ice tray 13, the defrosting device 10 includes a switching turntable 19. The switching turntable 19 is connected to one end of the drive shaft 18 away from the drive source 17 and rotates coaxially with the drive shaft 18. When the drive source 17 drives the drive shaft 18 to rotate, it also drives the switching turntable 19 to rotate together. The switching turntable 19 includes an arc-shaped sliding groove 30 and a limiting projection 21. The sliding groove 30 is formed on the side of the switching turntable 19 facing the drive shaft 18 and is formed on a part of the circumferential direction of the switching turntable 19. The limiting projection 21 is provided on the part of the circumferential direction of the switching turntable 19 where the sliding groove 30 is not formed. Limiting members 22 are provided on the sides of the first ice tray 12 and the second ice tray 13 facing the switching turntable 19. The limiting members 22 move in an arc relative to the sliding groove 30 and are clamped to the limiting projections 21. When the first ice tray 12 and the second ice tray 13 perform a flipping movement back to back, the limiting members 22 move in an arc along the sliding groove 30. When the limiting members 22 abut against the limiting projections 21 of the switching turntable 19, the sides of the first ice tray 12 and the second ice tray 13 abutting against the switching turntable 19 are relatively stationary and stop performing the flipping movement. By setting the limiting members 22 to match the limiting projections 21, it is beneficial to realize the limiting of the switching turntable 19 to the sides of the first ice tray 12 and the second ice tray 13 close to the switching turntable 19.

[0049] In some embodiments, the housing 11 includes a turntable cover 23. The turntable cover 23 is provided on the switching turntable 19. The switching turntable 19 includes a ratchet 24. The ratchet 24 is provided on the side of the limiting projection 21 along the circumferential direction of the switching turntable 19. The turntable cover 23 is provided with a ratchet slot 25 on its circumferential direction facing the switching turntable 19. The size of the ratchet slot 25 matches that of the ratchet 24 and is used to clamp the ratchet 24. By providing the turntable cover 23 outside the switching turntable 19, it is beneficial to realize the protection of the switching turntable 19. The ratchet 24 in this embodiment includes a one-way ratchet 24. Through the cooperation of the ratchet 24 and the ratchet slot 25, the relative fixation of the switching turntable 19 and the turntable cover 23 during the rotation process is realized. When the ratchet 24 is clamped inside the ratchet slot 25, the drive shaft 18 cannot drive the switching turntable 19 to rotate in the direction of the protrusion 26 of the ratchet 24, which is beneficial to realize the one-way rotation of the switching turntable 19.

[0050] In some embodiments, a protective turntable 29 is provided outside the turntable cover 23. A circular baffle is provided on the circumferential direction of the protective turntable 29 for limiting the switching turntable 19. The inner diameter of the circular baffle is smaller than the diameter of the switching turntable 19, and the outer diameter is larger than the diameter of the switching turntable 19, which is used to prevent the switching turntable 19 from detaching from the drive shaft 18 and rotating due to the centrifugal force during the rotation process, causing damage.

[0051] In some embodiments, the outer periphery of the turntable cover 23 is provided with a plurality of protrusions 26, and the plurality of protrusions 26 are extended along the third direction. The protective turntable 29 includes a clamping member, and the clamping member clamps the plurality of protrusions 26. The plurality of protrusions 26 are used to clamp the protective turntable 29. More specifically, when the protective turntable 29 covers the switching turntable 19 and the turntable cover 23, the fasteners connected to the protective turntable 29 are buckled on the plurality of protrusions 26 to achieve relative fixation of the protective turntable 29, so as to improve the clamping performance of the protective turntable 29, thereby improving the safety of the switching turntable 19 and the turntable cover 23 during use. In other embodiments, by relatively disassembling and separating the fasteners from the plurality of protrusions 26, the protective turntable 29 can be relatively opened relative to the switching turntable 19, thereby achieving relative separation of the switching turntable 19 from the drive shaft 18, so that the first ice tray 12 and the second ice tray 13 can be disassembled and cleaned.

[0052] In some embodiments, the circumferential surface of the protective turntable 29 is provided with lines 27. By providing a plurality of lines 27 on the surface of the protective turntable 29, it is beneficial to increase the friction force of the circumference of the protective turntable 29, which is convenient for operators to screw.

[0053] In some embodiments, the turntable cover 23 is provided with a plurality of ventilation holes 28 in the circumferential direction facing the first ice tray 12 and the second ice tray 13. Since the cold air for making ice is transmitted from one end of the driving source 17, by providing a plurality of ventilation holes 28 in the circumferential direction facing the first ice tray 12 and the second ice tray 13, it is beneficial to improve the air circulation inside the device and improve the ice making performance.

[0054] The refrigerator provided in the present application includes a water tank, a water flow pipe, a heat preservation member and the above-mentioned deicing device 10. The water tank is connected to the deicing device 10 through the water flow pipe, and the heat preservation member covers the water tank, the water flow pipe and the deicing device 10. During use, the water tank injects cooling water into the deicing device 10 through the water flow pipe to cool and make ice. During the ice making and deicing process, the heat preservation member is covered on the water tank, the water flow pipe and the outer side of the deicing device 10 to keep the made ice warm and prevent the ice from melting quickly.

[0055] The ice removal device 10 provided by the present application includes a first state and a second state. In the first state, the first ice cells 14 of the first ice tray 12 open upward for water injection to make ice; in the second state, the second ice cells 15 of the second ice tray 13 open upward for water injection to make ice; the drive shaft 18 drives the switching turntable 19 to rotate in the first direction to switch between the first state and the second state, and the engaging direction of the ratchet 24 and the ratchet slot 25 is opposite to the first direction. In the first state, the first ice cells 14 with larger size open upward, and water is injected to make ice through the connected water flow pipe. The operator can select and set the ice-making duration. After the ice-making and ice-removing are completed, it can be switched to the second state with a smaller ice-making size for ice-making. During the switching process, the driving member 16 drives the first ice tray 12, the second ice tray 13 and the switching turntable 19 to rotate in the first direction. In this embodiment, the first direction is the counterclockwise direction. At this time, the cooperation direction of the ratchet 24 of the switching turntable 19 and the ratchet slot 25 is opposite to the first direction, and the switching turntable 19 rotates together with the driving member 16 without being resisted by the ratchet 24.

[0056] The ice removal device 10 provided by the present application further includes a third state. In the third state, the ratchet 24 abuts against the ratchet slot 25, and the limiting member 22 abuts against the limiting protrusion 21. One end of the drive source 17 twists relative to one end of the switching turntable 19 in the second direction for ice removal, and the second direction is opposite to the first direction. The third state provided by this embodiment can be used for ice removal. After the ice-making in the first ice tray 12 or the second ice tray 13 is completed, the driving member 16 drives the switching turntable 19 to rotate in the second direction. In this embodiment, the second direction is the clockwise direction. At this time, the limiting member 22 and the limiting protrusion 21 abut against each other, and the first ice tray 12 and the second ice tray 13 abut against one side of the switching turntable 19 and are relatively fixed. The first ice tray 12 and the second ice tray 13 twist relative to each other in the clockwise direction away from the switching turntable 19. During the twisting process, the ice in the ice cells falls off to complete ice removal.

[0057] Those skilled in the art will readily think of other embodiments of the present application after considering the specification and practicing the application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application.
