the refrigerator further includes:
a controller 40, configured to control the ice making evaporation pipe 302 to provide cold energy to the ice cube tray 20 and start timing when recognizing that the water injection operation to the ice cube tray 20 is completed; and when the timed time is less than a preset time threshold value, controlling the ice making fan 301 to stop working.
The ice cube tray 20 is used for making ice by water; in this embodiment, after the operation of filling water into the ice cube tray 20 is completed, the controller 40 controls the ice making evaporation pipe 302 in the ice making system 30 to operate, so that the ice making evaporation pipe 302 provides cold to the ice cube tray 20 attached thereto, so that the water in the ice cube tray 20 is cooled and frozen; meanwhile, the timing is started, and when the timing time does not reach the time threshold, the ice making fan 301 is always controlled to stop working, that is, the cold air supply to the ice making chamber 101 is stopped, so that the problem that the cold energy provided by the ice making evaporation pipe 302 to the ice making grid 20 is blown to the ice making chamber 101 due to the working of the ice making fan 301 is avoided, and the problem of reduction of the cold energy for making ice is avoided.
In the embodiment of the invention, when the controller 40 recognizes that the operation of filling water into the ice cube tray 20 is completed, the ice making evaporation pipe 302 is controlled to provide cold energy to the ice cube tray 20 to make ice, and at the same time, timing is started, and when the timed time is smaller than a preset time threshold, the ice making fan 301 is controlled to stop working, so that the starting of the ice making fan 301 is forcibly delayed during ice making, and the problem that the cold energy provided by the ice making evaporation pipe 302 to the ice cube tray 20 is blown to the ice making chamber 101 due to the working of the ice making fan 301 to reduce the cold energy used for making ice is avoided, so that the water in the ice cube tray 20 is rapidly cooled by preferentially utilizing the cold energy of the ice making evaporation pipe 302, the ice making speed of the refrigerator is increased, and the ice making amount of the refrigerator is increased.
As shown in fig. 2, in order to make the ice making evaporation tube 302 provide cold energy to the ice cube tray 20, the ice making system 30 in this embodiment further includes:
a compressor 303;
a condenser 304, wherein the input end of the condenser 304 is connected with the output end of the compressor 303;
a dry filter 305, wherein the input end of the dry filter 305 is connected with the output end of the condenser 304;

an input end of the evaporator 307 is connected with an output end of the ice making evaporation pipe 302, and an output end of the evaporator 307 is connected with an input end of the compressor 303.
Specifically, in the embodiment of the present invention, the operation process of the ice making system 30 specifically includes:
when the compressor 303 starts to operate, a low-temperature and low-pressure refrigerant is sucked into the compressor 303, compressed into a high-temperature and high-pressure refrigerant gas in the compressor 303, and discharged into the condenser 304, and the high-temperature and high-pressure refrigerant gas is radiated by the condenser 304, gradually cooled to a normal-temperature and high-pressure saturated vapor, and further cooled to a saturated liquid; after moisture and impurities in the condensed refrigerant saturated liquid are filtered by the drying filter 305, the condensed refrigerant saturated liquid flows into the capillary tube 306, is throttled and depressurized by the capillary tube 306, and is converted into normal-temperature low-pressure wet steam; the refrigerant flowing out of the capillary tube 306 flows into the ice making evaporation tube 302, and starts to absorb heat in the ice making evaporation tube 302 for gasification, so that the temperature of the ice cube tray 20 attached to the ice making evaporation tube 302 is reduced, and cold energy is provided for the ice cube tray 20; the refrigerant flowing out of the ice-making evaporation tube 302 flows into the evaporator 307, and further absorbs heat in the evaporator 307 to be vaporized, thereby lowering the temperature of the evaporator 307 and its surroundings; the low-temperature and low-pressure refrigerant flowing out of the evaporator 307 flows back to the compressor 303 again, and the above process is repeated. In addition, when the ice making fan 301 operates, cold air is supplied to the ice making chamber 101 so that the temperature of the ice making chamber 101 is maintained within a preset temperature range.
In the embodiment of the present invention, by providing the compressor 303, the condenser 304, the dry filter 305, the capillary tube 306, the ice making evaporation tube 302 and the evaporator 307, and circulating a refrigerant in the compressor 303, the condenser 304, the dry filter 305, the capillary tube 306, the ice making evaporation tube 302 and the evaporator 307 in sequence when the ice making system 30 is in operation, the ice making evaporation tube 302 provides cold energy to the ice making cells 20 to make ice.
In the embodiment of the present invention, the type of the ice cube tray 20 may be set according to actual use conditions, and only the requirement of ensuring that ice can be made by using the cold energy provided by the ice making evaporation tube 302 is satisfied. In order to simplify the structure and ensure the ice making speed of the refrigerator, the ice cube tray 20 is preferably a metal ice cube tray in this embodiment.
In a preferred embodiment, the controller 40 is further configured to detect the temperature of the ice making chamber 101 when the timed time is greater than or equal to the time threshold; and when the temperature of the ice making chamber 101 is detected to be greater than a preset temperature threshold value, the ice making fan 301 is controlled to start working.
It is understood that after the timed time is greater than or equal to the time threshold, it indicates that the ice making is primarily completed; at this time, when it is detected that the temperature of the ice making chamber 101 is greater than the preset temperature threshold, it indicates that the temperature in the ice making chamber 101 is too high to store ice, so the ice making fan 301 is controlled to start to operate, and cold air is provided to the ice making chamber 101 to reduce the temperature of the ice making chamber 101, so that the temperature of the ice making chamber 101 can be maintained within the preset temperature range, and thus the ice can be stored in the ice making chamber 101.
In the embodiment of the present invention, the refrigerator further includes a temperature sensor, the temperature sensor is disposed in the ice making chamber 101, and an output end of the temperature sensor is connected to an input end of the controller 40. The temperature sensor enables the controller 40 to detect the temperature of the ice making compartment 101.
In addition, it should be noted that the time threshold of the present embodiment may be set according to an actual use situation, and the present invention is not limited to this.
In a preferred embodiment, the controller 40 is further configured to detect the temperature of the ice making compartment 101 upon recognizing that the water filling operation into the ice making compartment 20 is not completed; and when the temperature of the ice making chamber 101 is detected to be greater than a preset temperature threshold value, the ice making fan 301 is controlled to start working.
Specifically, when the operation of filling water into the ice making compartment 20 is not completed, the ice making evaporation pipe 302 has not yet started to supply cold to make ice; at this time, when it is detected that the temperature of the ice making chamber 101 is greater than the preset temperature threshold, it indicates that the temperature in the ice making chamber 101 is too high to facilitate ice making, so that the ice making fan 301 is controlled to start to operate to provide cold air to the ice making chamber 101 to reduce the temperature of the ice making chamber 101, so that the temperature of the ice making chamber 101 can be maintained within a preset temperature range to provide a suitable ice making environment, thereby facilitating ice making after the operation of filling water into the ice making tray 20 is completed.
In a preferred embodiment, the controller 40 is further configured to control the ice making fan 301 to stop operating when the temperature of the ice making chamber 101 is detected to be less than or equal to the temperature threshold.
Specifically, when the controller 40 detects that the temperature of the ice making chamber 101 is less than or equal to the temperature threshold, it indicates that the temperature in the ice making chamber 11 is proper, and thus controls the ice making fan 301 to stop working to stop providing cold air to the ice making chamber 101, so as to reduce the power consumption of the refrigerator while ensuring that the temperature of the ice making chamber 101 can be maintained within a preset temperature range, so as to ensure that the refrigerator has a good energy saving effect.
In addition, it should be noted that the temperature threshold of the present embodiment may be set according to actual use situations, and the present invention is not limited to this.
