[0059] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0060] See also Figure 1 The utility model provides a refrigerator, including a box body 1 and an ice-making assembly 2. The box body 1 is provided with a refrigerating chamber 121 and a freezing chamber 122. The ice-making assembly 2 is arranged in the refrigerating chamber 121 and uses the cold air of the freezing chamber 122 to make ice.

[0061] See also Figure 1 and Figure 2 In some embodiments, the box body 1 is roughly a rectangular frame structure. The box body 1 includes a box shell 11 and a box liner 12. The box liner 12 is arranged in the box shell 11.

The interior of the box liner 12 forms a storage space for storing food. The box shell 11 provides protection and support for the box liner 12.

[0062] See also Figure 1 and Figure 2In some embodiments, a refrigeration chamber is formed inside the box 12, and the refrigeration chamber is divided into a refrigerator 121 and a freezer 122. The refrigerator 121 is located at the upper part of the box 12, and the freezer 122 is located at the lower part of the box 12. It should be pointed out that the position of the refrigerator 121 and the freezer 122 can also be set upside down. One side of the refrigerator 121 and one side of the freezer 122 are provided with access ports to facilitate the access of items. A door body is connected to the access port, and the door body can be connected to the box 1 in an openable and closable manner to open or close the access port. For example, the door body and the box 1 can be rotatably connected or slidably connected.

[0063] In some embodiments, the refrigerator also includes a refrigeration system (not shown) and an air supply system (not shown), and the refrigeration system and the air supply system are electrically connected to a power supply component, and the power supply component is used to supply electricity to various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0064] The refrigeration system is installed in the box 1, and the refrigeration system is used to provide cold air to the refrigeration chamber inside the box 12. The refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device and a refrigerant. Each component is distributed at different positions of the box 1 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after plugging in the power cord of the refrigerator, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device. The throttling device is used to throttle and reduce the pressure, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0065] The air supply system is installed in the box 1 to provide power for the flow of cold air; the air supply system generally includes a fan and an air supply duct defined in the box 1. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan; in other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box 1 is also defined to form an air duct cavity, which is respectively connected to the air supply duct and the refrigeration chamber inside the box, so that the air supply duct is connected to the refrigeration chamber through the air duct cavity; it should be noted that the box 12 is provided with an air outlet, which is used to connect the air duct cavity and the refrigeration chamber. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber to cool the refrigeration chamber. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall of the box 12 on the side opposite to the opening of the refrigeration chamber or on the side wall of the box 12 adjacent to the opening of the refrigeration chamber; it should also be noted that the refrigeration system and the air supply system belong to common knowledge in the field and will not be described in detail here.

[0066] See also Figure 4 - Figure 6 , Fig.15 - Fig.16 In some embodiments, the ice-making assembly 2 includes an ice-making box assembly 21 and an ice-storage box assembly 22. The ice-making box assembly 21 is used for making ice, and the ice-storage box assembly 22 is used for storing ice. The ice-making box assembly 21 includes an outer frame 211, a back plate 212, and an ice-making machine 213 disposed in the outer frame 211.

The outer frame 211 has a first end 21101 and a second end 21102 that are disposed opposite to each other. The first end 21101 and the second end 21102 are both open. The first end 21101 is disposed opposite to the inner wall of the refrigerating chamber 121, and the second end 21102 is disposed opposite to each other. 102 is connected to the panel assembly 221, so that the ice storage box 222 is inserted into the outer frame 211 and placed below the ice maker 213; the back plate 212 is arranged near the first end 21101 and is connected to the outer frame 211, and an air supply port 2121 and an air return port 2122 are provided on the back plate 212. The cold air of the freezer chamber 122 is sent into the ice maker 213 through the air supply port 2121 for heat exchange, and the cold air of the heat exchange flows back to the freezer chamber 122 through the return air port 2122, forming a refrigeration cycle.

[0067] By integrating the panel assembly 221 and the ice storage box 222, and integrating the outer frame 211, the back plate 212 and the ice maker 213, the ice making assembly 2 is modularized, which is convenient and quick to assemble and improves efficiency. In addition, when the ice maker 213 or the ice storage box 222 needs to be disassembled for maintenance, the ice making box assembly 21 and the ice storage box assembly 22 are separated, and then the ice maker 213 or the ice storage box 22 is disassembled. When the ice maker 213 is disassembled, the overall structure of the ice storage box assembly 22 will not be affected, and when the ice storage box 222 is disassembled, the overall structure of the ice making box assembly 21 will not be affected, so that it is convenient to disassemble and maintain each component separately.

[0068] It should be noted that the first end 21101 and the second end 21102 of the outer frame 211 are both opened, and the first end 21101 and the second end 21102 may be completely open, or the first end 21101 and the second end 21102 may be only partially open, for example, only the middle of the first end 21101 and the second end 21102 is opened. The first end 21101 is arranged opposite to the inner wall of the refrigerating chamber 121, and may be connected or not connected with a certain interval.

[0069] See also Figure 7 and Figure 8 In some embodiments, the outer frame 211 is a four-sided frame structure. The ice maker 213 is fixed to the top surface of the outer frame 211, and the ice storage box 222 is inserted into the outer frame 211 and is located on the bottom surface of the outer frame 211 and below the ice maker 213 to facilitate receiving and transporting ice cubes made by the ice maker 213.

[0070] The outer frame 211 can be an integral frame or a split frame. Figure 8In some embodiments, the outer frame 211 is a split frame, and the outer frame 211 includes a first frame body 2111 and a second frame body 2112. The first frame body 2111 includes a first side wall 21111 and a second side wall 21112 connected to each other. The first side wall 21111 and the second side wall 21112 are respectively arranged adjacent to the inner wall of the refrigerating chamber 121, and the ice maker 213 is fixed on the first side wall 21111; the second frame body 2112 includes a third side wall 21121 and a fourth side wall 21122 connected to each other. The third side wall 21121 is arranged opposite to the first side wall 21111 and connected to the second side wall 21112. The fourth side wall 21122 is arranged opposite to the second side wall 21112 and connected to the first side wall 21111. The outer frame 211 is set as a split frame to facilitate the assembly and disassembly of the outer frame 211. The first frame 2111 and the second frame 2112 are both L-shaped. After the first frame 2111 and the second frame 2112 are connected, the first side wall 21111, the second side wall 21112, the third side wall 21121 and the fourth side wall 21122 are connected to form a four-sided frame structure, and openings are reserved at both ends. It should be pointed out that the first side wall 21111 and the second side wall 21112 in the first frame 2111 can be detachably connected, fixedly connected or integrally formed, and the third side wall 21121 and the fourth side wall 21122 in the second frame 2112 can be detachably connected, fixedly connected or integrally formed. The first side wall 21111 and the second side wall 21112 are respectively arranged adjacent to the inner wall of the cold storage chamber 121, and one or two of the first side wall 21111 and the second side wall 21112 can be connected to the inner wall of the cold storage chamber 121, or can be unconnected and have a certain interval.

[0071] See also Figure 8In some embodiments, the outer frame 211 further includes a heat preservation layer. The first frame 2111 and / or the second frame 2112 include an inner layer 21131 and an outer layer 2113, the outer layer 2113 covers the inner layer 21131, and a heat preservation layer (not shown in the figure) is filled between the outer layer 2113 and the inner layer 21131. The heat preservation layer is arranged between the inner layer 21131 and the outer layer 2113 of the first frame 2111 and / or the second frame 2112, and the heat preservation layer is used to isolate the cold air and hot air outside the outer frame 211. Since one of the first frame 2111 and the second frame 2112 needs to be attached to the box 12 when the outer frame 211 is installed, the heat preservation layer can be only arranged in the first frame 2111 or the second frame 2112. For example, when the ice box assembly 21 is installed at the upper left corner of the refrigerating chamber 121, the first frame 2111 is attached to the box 12, and the insulation layer can be only provided in the second frame 2112; when the ice box assembly 21 is installed at the upper right corner of the refrigerating chamber 121, the second frame 2112 is attached to the box 12, and the insulation layer can be only provided in the first frame 2111. In other embodiments, the insulation layer can be provided in both the first frame 2111 and the second frame 2112. It should be noted that the structural shape of the insulation layer is the same as the structural shape of the first frame 2111 or the second frame 2112. For example, when the first frame 2111 and the second frame 2112 are both L-shaped, the insulation layer is also L-shaped accordingly.
