The refrigerator has a compressor, an ice maker for freezing a cabinet or box, and a storage box with a refrigeration device. The ice maker in the refrigerator is generally fixed in the cold storage room. The ice maker is divided into a direct cooling ice maker and an air-cooled ice maker. The direct cooling ice maker uses a refrigeration pipe to insert into the ice making room of the ice maker to transport cold air into the ice making room for ice making; the air-cooled ice maker needs to be provided with an air supply port to transport cold air into the ice making room, and a return air port is provided to output the cold air in the ice making room to form a refrigeration air circuit cycle.

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053] See also Figure 1 - Figure 2 As shown, an embodiment of 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 in the freezing chamber 122 to make ice.

[0054] See also Figure 1In 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.

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.

[0056] 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.

[0057] 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.

[0058] 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.
