Description

Technical Field

[0001] The invention relates to the field of household appliances, in particular to a refrigerator. Background Art

[0002] At present, refrigerators have become an indispensable household appliance in family life. Some refrigerators are equipped with an ice-making compartment in the refrigeration door or the refrigeration compartment. The refrigerator is generally equipped with a dual-system refrigeration system, including an ice-making evaporator that supplies cold air to the ice-making compartment and a cabinet evaporator that supplies cold air to the refrigeration compartment and the freezer compartment in the cabinet. The ice-making evaporator and the cabinet evaporator share a compressor. By controlling the flow direction of the refrigerant after passing through the compressor, the refrigeration of the ice-making evaporator or the refrigeration of the cabinet evaporator can be controlled.

[0003] When the refrigerator is operating normally, the operation of the compressor and the flow of the refrigerant are generally controlled according to the temperature in the ice making room and the temperature in the freezer. However, in special cases such as when the refrigerator is powered on after a power outage, the flow of the refrigerant cannot be well controlled to reduce the damage caused by the power outage, which may cause the ice to melt and the melted water to overflow to the outside of the refrigerator. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a refrigerator, which controls a refrigeration system according to the amount of ice in an ice storage box when the refrigerator is powered on.

[0005] To achieve one of the above-mentioned purposes, an embodiment of the present invention provides a refrigerator, comprising:

[0006] The box body has storage compartments formed therein including a refrigerating compartment and a freezing compartment;

[0007] A refrigeration door body connected to the box body and used for opening and closing the refrigeration compartment;

[0008] An ice-making chamber is arranged in the refrigeration door, in the refrigeration chamber or independently formed in the box;

[0009] An ice storage box, which is arranged in the ice making room;

[0010] An ice quantity detection module is placed in the ice making room and is used to detect ice quantity information in the ice storage box;

[0013] A refrigeration system, comprising a compressor, a refrigerant control valve, an ice-making evaporator arranged corresponding to the ice-making compartment, and a box evaporator arranged corresponding to the storage compartment, wherein the refrigerant control valve comprises a refrigerant inlet, an ice-making refrigerant outlet, and a box refrigerant outlet, wherein the refrigerant inlet is connected to the compressor side, the ice-making refrigerant outlet is connected to the ice-making refrigerant branch where the ice-making evaporator is located, and the box refrigerant outlet is connected to the box refrigerant branch where the box evaporator is located;

[0014] The refrigerator further comprises a control module, which is configured as follows:

[0015] When a refrigerator power-on signal is received, the ice-making compartment temperature detected by the ice-making compartment temperature sensor and the storage compartment temperature detected by the cabinet temperature sensor are acquired;

[0016] If the current temperature of the ice-making compartment is greater than the second preset temperature, and the current temperature of the storage compartment is greater than the first preset temperature, the compressor is controlled to start, and the ice amount information detected by the ice amount detection module is obtained. If the ice amount in the ice storage box is greater than the preset value, the refrigerant control valve is controlled to open the ice-making refrigerant outlet first, and when it is monitored that the temperature of the ice-making compartment reaches the preset ice-making refrigeration system shutdown temperature, the refrigerant control valve is controlled to close the ice-making refrigerant outlet.

[0017] As a further improvement of an embodiment of the present invention, the control module is specifically configured as follows:

[0018] If the amount of ice in the ice storage box is greater than a preset value, the refrigerant control valve is controlled to continuously open the ice-making refrigerant outlet first, and when it is monitored that the temperature of the ice-making compartment reaches a preset ice-making refrigeration system shutdown temperature, the refrigerant control valve is controlled to close the ice-making refrigerant outlet and open the box refrigerant outlet.

[0019] As a further improvement of an embodiment of the present invention, the control module is specifically configured as follows:

[0020] If the amount of ice in the ice storage box is greater than a preset value, the refrigerant control valve is controlled to periodically open the ice-making refrigerant outlet for a first preset time, then close the ice-making refrigerant outlet and open the cabinet refrigerant outlet for a second preset time, and the first preset time is greater than the second preset time.

[0021] As a further improvement of an embodiment of the present invention, the control module is further configured as follows:

[0022] When it is monitored that the temperature of the ice-making compartment reaches a preset ice-making refrigeration system shutdown temperature, the refrigerant control valve is controlled to continuously close the ice-making refrigerant outlet and continuously open the cabinet refrigerant outlet.

[0023] As a further improvement of an embodiment of the present invention, when the ice-making refrigerant outlet is opened for a first preset time, the volume of the refrigerant in the ice-making evaporator is equal to the capacity of the ice-making evaporator.

[0024] As a further improvement of an embodiment of the present invention, the control module is further configured as follows:

[0025] If the amount of ice in the ice storage box is greater than a preset value, when it is monitored that the temperature of the storage compartment reaches the shutdown temperature of the cabinet refrigeration system and the temperature of the ice making compartment is less than the second preset temperature, the compressor is controlled to be turned off.

[0026] As a further improvement of an embodiment of the present invention, the control module is further configured as follows:

[0027] If the amount of ice in the ice storage box is less than a preset value, the refrigerant control valve is controlled to open the cabinet refrigerant outlet first, and when it is monitored that the temperature of the storage compartment reaches a preset cabinet refrigeration system shutdown temperature, the refrigerant control valve is controlled to close the cabinet refrigerant outlet.

[0028] As a further improvement of an embodiment of the present invention, the control module is specifically configured as follows: if the amount of ice in the ice storage box is less than a preset value, the refrigerant control valve is controlled to continuously open the cabinet refrigerant outlet first, and when it is monitored that the temperature of the storage compartment reaches a preset cabinet refrigeration system shutdown temperature, the refrigerant control valve is controlled to close the cabinet refrigerant outlet and open the ice-making refrigerant outlet.

[0029] As a further improvement of an embodiment of the present invention, the control module is specifically configured as follows:

[0030] If the amount of ice in the ice storage box is less than a preset value, the refrigerant control valve is controlled to periodically open the cabinet refrigerant outlet for a third preset time, then close the cabinet refrigerant outlet and open the ice-making refrigerant outlet for a fourth preset time, and the third preset time is greater than the fourth preset time;

[0031] When it is monitored that the temperature of the storage compartment reaches a preset cabinet refrigeration system shutdown temperature, the refrigerant control valve is controlled to continuously close the cabinet refrigerant outlet and continuously open the ice-making refrigerant outlet.

[0032] As a further improvement of an embodiment of the present invention, the control module is further configured as follows:

[0033] If the amount of ice in the ice storage box is less than a preset value, when the temperature in the ice-making room reaches the corresponding ice-making refrigeration system shutdown temperature and the temperature in the storage room is less than the first preset temperature, the compressor is controlled to be turned off.

[0034] The refrigerator provided by the present invention controls the flow direction of the refrigerant according to the ice amount information in the ice storage box when the refrigerator is powered on again after a power outage. When ice cubes are stored in the ice storage box, the refrigerant is preferentially supplied to the ice-making evaporator to preferentially supply cold air to the ice-making compartment, thereby reducing the melting of the ice cubes in the ice storage box and reducing the risk of melted water of the ice cubes in the ice storage box overflowing to the outside of the refrigerator. When no ice cubes are stored in the ice storage box, cold air is preferentially supplied to the storage compartment, thereby reducing the risk of damage to food in the storage compartment.

[0039] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] See also Figures 1 to 3The present invention provides a refrigerator 100, including a box body 110 and a door body of the box body 110 connected to the box body 110 for opening and closing the box body 110. A storage compartment for storing food is formed in the box body 110, and the storage compartment may include a refrigerating compartment 111 and a freezing compartment 112. The door body may include a refrigerating door body 121 for opening and closing the refrigerating compartment 111 and a freezing door body 122 for opening and closing the freezing compartment 112. The refrigerator 100 may be provided with an ice-making compartment 130, and the ice-making compartment 130 may be provided inside the refrigerating compartment 111, such as providing an independent ice-making compartment 130 isolated from the refrigerating compartment 111 on the top of the refrigerating compartment 111. The ice-making compartment 130 may also be arranged on the refrigerating door 121, or independently formed in the box body 110, such as a storage compartment and an ice-making compartment 130 parallel to the storage compartment may be formed in the box body 110, and the ice-making compartment 130 is relatively independent from the refrigerating compartment 111 and the freezing compartment 112.

[0041] The ice making chamber 130 may be provided with an ice making device 131 and an ice storage box 132. The ice making device 131 may be used to receive liquid water and make ice. The ice storage box 132 may be placed below the ice making device 131 to receive and store ice cubes made by the ice making device 131. The user may take out the ice storage box 132 from the ice making chamber 130 to take out ice.

[0042] See also Figure 3 The refrigerator door 121 of the refrigerator 100 may be provided with a dispenser 123, which may be connected to the ice storage box 132. The user may directly take out the ice cubes in the ice making chamber 130 from the outside of the refrigerator 100 through the dispenser 123. A dispenser recess may be provided on the outside of the refrigerator door 121, and the ice outlet of the dispenser 123 is placed in the dispenser recess. A water receiving tray 124 may also be provided in the dispenser recess. When the ice cubes in the ice storage box melt, the melted water may drip into the water receiving tray 124 through the ice outlet of the dispenser 123. When there is too much water in the water receiving tray 124, the water will overflow to the ground.

[0043] An ice quantity detection module may also be installed in the ice making room 130. The ice quantity detection module can be used to detect the ice quantity information in the ice storage box 132. The ice quantity detection module may be a pressure sensor arranged at the bottom of the ice storage box 132. The ice quantity information in the ice storage box 132 is determined according to the detected pressure information. The ice quantity detection module may also be an infrared sensor, an ultrasonic sensor or any other module installed on the ice storage box 132 that can detect the ice quantity information in the ice storage box 132.

[0044] An ice-making compartment temperature sensor may be provided inside the ice-making compartment 130 of the refrigerator 100 for detecting the temperature information of the ice-making compartment 130, and a cabinet temperature sensor for detecting the temperature inside the storage compartment may also be installed inside the storage compartment. In this embodiment, the cabinet temperature sensor may include a refrigerating compartment temperature sensor installed inside the refrigerating compartment 111 and a freezing compartment temperature sensor installed inside the freezing compartment 112.

[0045] The refrigerator 100 is provided with a refrigeration system 200 for supplying cold air to the storage compartment and the ice making compartment 130. Figure 4 , the refrigeration system 200 may include a compressor 210, a refrigerant control valve 220, an ice-making evaporator 231 corresponding to the ice-making compartment 130, and a cabinet evaporator 241 corresponding to the storage compartment. The refrigerant control valve 220 may be a one-inlet and multiple-outlet solenoid valve, and the refrigerant control valve 220 may include a refrigerant inlet, an ice-making refrigerant outlet, and a cabinet refrigerant outlet. The refrigerant inlet may be connected to the compressor 210 side, the ice-making refrigerant outlet may be connected to the ice-making refrigerant branch 230 where the ice-making evaporator 231 is located, and the cabinet refrigerant outlet may be connected to the cabinet refrigerant branch 240 where the cabinet evaporator 241 is located.

[0046] In this embodiment, the refrigeration system 200 can be installed on one side of the box 110, and a compressor compartment, a box evaporator chamber and an ice-making evaporator chamber can be provided on one side of the box 110. The compressor 210 can be installed in the compressor compartment, and the refrigerant control valve 220 can also be installed in the compressor compartment. The box evaporator 241 can be installed in the box evaporator chamber, and the ice-making evaporator 231 can be installed in the ice-making evaporator chamber. Air supply fans can be installed in the ice-making evaporator chamber and the box evaporator chamber. The ice-making evaporator chamber can be connected to the ice-making chamber 130 through an air duct. The cold air in the ice-making evaporator chamber can be supplied to the ice-making chamber 130 through the air supply fan. The box evaporator chamber can be connected to the storage chamber through the air duct. The cold air in the box evaporator chamber can be supplied to the storage chamber through the air supply fan in the box evaporator chamber.

[0047] The refrigeration system 200 may further include a condenser installed between the compressor 210 and the refrigerant control valve 220, an ice-making capillary tube placed between the ice-making refrigerant outlet and the ice-making evaporator 231, and a box capillary tube placed between the box refrigerant outlet and the box evaporator 241. During the refrigeration process, the compressor 210 is turned on to compress the refrigerant, and the refrigerant compressed by the compressor 210 flows through the condenser and then controls the flow direction through the refrigerant control valve 220. If the ice-making refrigerant outlet of the refrigerant control valve 220 is opened, the refrigerant passes through the refrigerant control valve 220 and then flows through the ice-making refrigerant branch 230 formed by the ice-making capillary tube and the ice-making evaporator 231, and then returns to the compressor 210. Correspondingly, if the box refrigerant outlet of the refrigerant control valve 220 is opened, the refrigerant passes through the refrigerant control valve 220 and then flows through the box refrigerant branch 240 formed by the box capillary tube and the box evaporator and returns to the compressor 210.

[0048] In one embodiment of the present invention, the cabinet evaporator 241 may include two independent evaporators respectively arranged corresponding to the refrigerating compartment 111 and the freezing compartment 112, and the cabinet refrigerant outlet of the refrigerant control valve 220 may also include two refrigerant outlets respectively corresponding to the two evaporators.

[0049] In one embodiment of the present invention, the refrigerator 100 further includes a control module, which can be configured as follows:

[0050] When receiving a power-on signal of the refrigerator 100, the temperature of the ice-making compartment detected by the ice-making compartment temperature sensor and the temperature of the storage compartment detected by the cabinet temperature sensor are obtained;

[0051] If the current temperature of the ice-making chamber 130 is greater than the second preset temperature, and the temperature of the storage chamber is greater than the first preset temperature, the compressor 210 is controlled to turn on, and the ice quantity information detected by the ice quantity detection module is obtained. If the ice quantity in the ice storage box is greater than the preset value, the refrigerant control valve 220 is controlled to open the ice-making refrigerant outlet first, and when it is monitored that the temperature of the ice-making chamber 130 reaches the preset ice-making refrigeration system shutdown temperature, the refrigerant control valve 220 is controlled to close the ice-making refrigerant outlet, wherein the first preset temperature is greater than or equal to the preset box refrigeration system shutdown temperature, and the second preset temperature is greater than or equal to the preset ice-making refrigeration system shutdown temperature.

[0052] In this embodiment, the first preset temperature is less than or equal to the preset box refrigeration system startup temperature, and the second preset temperature is less than or equal to the preset ice-making refrigeration system startup temperature. The ice-making refrigeration system startup temperature and the box refrigeration system startup temperature are both preset temperatures. When the temperature of the ice-making compartment 130 is greater than the ice-making refrigeration system startup temperature during normal operation of the refrigerator, it can be determined that the temperature in the ice-making compartment 130 is high, which may affect the operation of the ice-making device 131 and the storage of ice cubes in the ice storage box 132. At this time, it is necessary to turn on the refrigeration system 200 to supply cold air to the ice-making compartment 130. Similarly, when the temperature of the storage compartment is greater than the box refrigeration system startup temperature, it can be determined that the temperature in the storage compartment is too high, which affects the storage of food, and it is necessary to turn on the refrigeration system 200 to supply cold air to the storage compartment.

[0053] In addition, the refrigerator 100 is also pre-set with an ice-making refrigeration system shutdown temperature. When the refrigeration system 200 is turned on to supply cold air to the ice-making compartment 130, if the temperature of the ice-making compartment 130 drops to the preset ice-making refrigeration system shutdown temperature, it can be determined that the temperature of the ice-making compartment 130 has reached a temperature at which normal operation can be performed, and refrigerant can no longer be supplied to the ice-making evaporator 231 to stop refrigerating the ice-making compartment 130. Similarly, in the process of refrigerating the storage compartment, if the temperature of the storage compartment drops to the corresponding box refrigeration system shutdown temperature, the supply of refrigerant to the box evaporator 241 can be stopped to stop supplying cold air to the storage compartment.

[0054] In this embodiment, when the refrigerator is powered on, when the temperature of the storage compartment is higher than the corresponding cabinet refrigeration system shutdown temperature or the temperature of the ice-making compartment is higher than the corresponding ice-making refrigeration system shutdown temperature, the compressor is turned on for cooling, thereby quickly lowering the compartment temperature and reducing the negative impact of power outages.

[0055] In this embodiment, if the refrigerating compartment 111 and the freezing compartment 112 share a cabinet evaporator 241, when the temperatures in the refrigerating compartment 111 and the freezing compartment 112 both drop to the corresponding refrigeration system shutdown temperature, the supply of refrigerant to the cabinet evaporator 241 is stopped. If only one of them reaches the corresponding refrigeration system shutdown temperature, the corresponding air supply fan and damper can be controlled to close to block the supply of cold air.

[0056] In this embodiment, since the ice-making evaporator 231 and the cabinet evaporator 241 share a compressor 210, in order to ensure the refrigeration system 200 and facilitate control, refrigerant is often only supplied to one evaporator during the refrigeration process. If the refrigerator 100 is powered off and then powered on again, and only the ice-making compartment 130 or the storage compartment needs to be refrigerated, the refrigerant control valve 220 is controlled to open the corresponding refrigerant outlet to supply refrigerant to the corresponding evaporator.

[0057] When the refrigerator 100 is powered on again after being powered off, if both the ice-making compartment 130 and the storage compartment need to be refrigerated, the refrigerant flow direction can be controlled according to the ice amount information in the ice storage box 132. If the ice amount in the ice storage box 132 is greater than the preset value, the refrigerant control valve 220 can be controlled to open the ice-making refrigerant outlet to supply the refrigerant to the ice-making refrigerant branch 230, so as to preferentially supply cold air to the ice-making compartment 130.

[0058] The preset value may be 0 or other values. When the preset value is 0, it is sufficient to detect whether ice is stored in the ice storage box.

[0059] After the refrigerant control valve 220 is controlled to open the ice-making refrigerant outlet first, the ice-making refrigerant outlet can be continuously opened or periodically opened intermittently. When the temperature of the ice-making chamber reaches the preset ice-making refrigeration system shutdown temperature, the refrigerant control valve can be controlled to continuously close the ice-making refrigerant outlet until the temperature of the ice-making chamber is greater than the ice-making refrigeration system startup temperature, or other situations occur that require the ice-making chamber to be cooled.

[0060] In this way, when the refrigerator 100 is powered on again after being powered off, if ice cubes are stored in the ice storage box 132, cold air is supplied to the ice making compartment 130 first, thereby preventing the ice cubes in the ice storage box 132 from melting too much. The melted liquid water flows from the ice outlet pipe of the dispenser 123 and other structures to the outside of the refrigerator 100, affecting the user experience.

[0061] Furthermore, in the first embodiment provided by the present invention, the control module is specifically configured as follows:

[0062] If the amount of ice in the ice storage box is greater than a preset value, the refrigerant control valve 220 is controlled to continuously open the ice-making refrigerant outlet, and when the temperature of the ice-making chamber 130 is monitored to reach the preset ice-making refrigeration system shutdown temperature, the refrigerant control valve 220 is controlled to close the ice-making refrigerant outlet and open the refrigerant outlet of the box body 110.

[0063] In this embodiment, when the refrigerator 100 is powered on again after being powered off, if there are still ice cubes stored in the ice storage box 132, the refrigerant control valve 220 is controlled to continuously open the ice-making refrigerant outlet corresponding to the ice-making evaporator 231, and the temperature of the ice-making compartment 130 is preferentially reduced to the ice-making refrigeration system shutdown temperature corresponding to the ice-making compartment 130, and then the cabinet refrigerant branch 240 corresponding to the cabinet evaporator 241 is controlled to open to cool the storage compartment.

[0064] In this way, the control can be simplified, the switching of the refrigerant control valve 220 can be reduced, and the ice making chamber 130 can be quickly cooled.

[0065] Furthermore, in this embodiment, the control module is further configured as follows:

[0066] If the amount of ice in the ice storage box 132 is greater than the preset value, when it is monitored that the temperature of the storage compartment reaches the shutdown temperature of the cabinet refrigeration system and the temperature of the ice making compartment 130 is less than the second preset temperature, the compressor 210 is controlled to be turned off.

[0067] In this embodiment, if ice cubes are stored in the ice storage box 132, the ice making chamber 130 is refrigerated first, and then the storage chamber is refrigerated. When the temperature of the storage chamber drops to the corresponding box refrigeration system shutdown temperature, the supply of refrigerant to the box evaporator 241 can be stopped, and the supply of cold air to the ice making chamber 130 can be stopped. If at this time, if the temperature of the ice making chamber 130 is lower than the second preset temperature, the compressor 210 can be turned off, the refrigeration is stopped, and the temperature of the ice making chamber 130 and the storage chamber are continuously monitored. When the temperature of the ice making chamber 130 is higher than the corresponding ice making refrigeration system startup temperature or the storage chamber temperature is higher than the corresponding box refrigeration system startup temperature, the compressor 210 can be controlled to start again, and the refrigerant control valve 220 can be controlled to open the corresponding refrigerant opening to supply refrigerant to the corresponding evaporator, thereby supplying cold air to the corresponding chamber.

[0068] Furthermore, in one embodiment of the present invention, the control module is further configured as follows:

[0069] If the amount of ice in the ice storage box 132 is less than a preset value, the refrigerant control valve 220 is controlled to open the cabinet refrigerant outlet first, and when the temperature of the storage compartment reaches the preset cabinet refrigeration system shutdown temperature, the refrigerant control valve 220 is controlled to close the cabinet refrigerant outlet.

[0070] In this embodiment, if the refrigerator 100 is powered on again after being powered off, it is detected that there is no ice cubes stored in the ice storage box 132 or the amount of stored ice is small. At this time, the amount of water melted from the ice cubes is small. After the melted water flows from the ice storage box and drips into the water receiving tray 124, it will not overflow from the water receiving tray 124. At this time, the storage room can be cooled first to reduce the risk of damage to food in the storage room.

[0071] In this embodiment, the control module can be specifically configured as follows:

[0072] If the amount of ice is less than a preset value, the refrigerant control valve 220 is controlled to continuously open the cabinet refrigerant outlet first, and when the temperature of the storage compartment is monitored to reach the preset cabinet refrigeration system shutdown temperature, the refrigerant control valve 220 is controlled to close the cabinet refrigerant outlet and open the ice-making refrigerant outlet.

[0073] The control module is further configured to control the compressor 210 to shut down when the temperature of the monitored ice-making compartment 130 reaches the corresponding ice-making refrigeration system shutdown temperature and the temperature of the storage compartment is lower than the corresponding first preset temperature.

[0074] In this embodiment, when the refrigerator 100 is powered on again after being powered off, if there is no ice cube stored in the ice storage box 132 or the amount of ice is small, the refrigerant can be controlled to be continuously supplied to the cabinet evaporator 241, and when the temperature of the cabinet 110 reaches the corresponding cabinet refrigeration system shutdown temperature, the refrigerant is continuously supplied to the ice-making evaporator 231 corresponding to the ice-making chamber 130 until the temperature in the ice-making chamber 130 drops to the ice-making refrigeration system shutdown temperature, and if the temperature of the storage room is still lower than the first preset temperature at this time, the refrigeration is terminated, the compressor 210 can be turned off, and the temperature of the ice-making chamber 130 and the storage room is continuously monitored. In this way, the switching of the refrigerant control valve 220 can be reduced, and the interior of the storage room can be quickly refrigerated.

[0075] In the second embodiment provided by the present invention, compared with the first embodiment, the main difference is that the control module is specifically configured as follows:

[0076] If the amount of ice in the ice storage box 132 is less than the preset value, the refrigerant control valve 220 is controlled to periodically open the cabinet refrigerant outlet for a third preset time, then close the cabinet refrigerant outlet and open the ice-making refrigerant outlet for a fourth preset time, wherein the third preset time is greater than the fourth preset time;

[0077] When the temperature of the storage compartment reaches the preset shutdown temperature of the box refrigeration system, the refrigerant control valve 220 is controlled to continuously close the box refrigerant outlet and continuously open the ice making refrigeration outlet;

[0078] When it is monitored that the temperature of the ice-making compartment 130 reaches the shutdown temperature of the ice-making refrigeration system, the compressor 210 is controlled to be shut down.

[0079] In this embodiment, if the amount of ice in the ice storage box 132 is less than a preset value and the risk of water overflowing from the water receiving tray 124 due to melting of the ice in the ice storage box is relatively small, the refrigerant control valve 220 can be controlled to alternately open the cabinet refrigerant outlet and the ice-making refrigerant outlet, and the opening time of the cabinet refrigerant outlet is greater than the opening time of the ice-making refrigerant outlet, thereby giving priority to cooling the storage room to ensure that the items in the storage room are not damaged.

[0080] When the refrigerant control valve 220 opens the cabinet refrigerant outlet for the third preset time, the refrigerant volume in the cabinet evaporator 241 is equal to the capacity of the cabinet evaporator 241. At this time, the cabinet evaporator 241 reaches the maximum cooling power. If the refrigerant is continuously supplied to the cabinet evaporator 241 at this time, energy will be wasted. In this way, the cabinet refrigerant outlet and the ice-making refrigerant outlet are opened alternately, and the refrigerant is alternately supplied to the cabinet evaporator 241 and the ice-making evaporator 231, which can reasonably utilize energy and save energy consumption.

[0081] The present invention further provides a third embodiment, which is an improvement on the refrigerator 100 of the first embodiment or the second embodiment. Compared with the first embodiment or the second embodiment, the main difference is that in this embodiment, the control module configuration is specifically configured as follows:

[0082] If the amount of ice in the ice storage box 132 is greater than the preset value, the refrigerant control valve 220 is controlled to periodically open the ice-making refrigerant outlet for a first preset time, then close the ice-making refrigerant outlet and open the cabinet refrigerant outlet for a second preset time, and the first preset time is greater than the second preset time.

[0083] The control module is also configured as:

[0084] When it is monitored that the temperature of the ice-making compartment 130 reaches the preset ice-making refrigeration system shutdown temperature, the ice-making agent control valve is controlled to continuously close the ice-making refrigerant outlet and continuously open the cabinet refrigerant outlet.

[0085] In this embodiment, in order to reasonably utilize energy, refrigerant is periodically supplied to the ice-making evaporator 231 and the cabinet evaporator 241, and refrigerant is first supplied to the ice-making evaporator 231, and more refrigerant is supplied to the ice-making evaporator 231 to achieve preferential cooling of the ice-making compartment 130. When the temperature of the ice-making compartment 130 reaches the corresponding ice-making refrigeration system shutdown temperature, the supply of refrigerant to the ice-making evaporator 231 can be stopped, and at this time, the supply of refrigerant to the cabinet evaporator 241 can continue.

[0086] In this embodiment, when the ice-making refrigerant outlet is opened for the first preset time, the volume of the refrigerant in the ice-making evaporator 231 may be equal to the capacity of the ice-making evaporator 231. At this time, the ice-making evaporator 231 reaches the maximum cooling capacity. If the refrigerant continues to be supplied to the ice-making evaporator 231, it will cause energy waste. Therefore, at this time, the refrigerant supply to the ice-making evaporator 231 can be stopped and the refrigerant can be supplied to the cabinet evaporator 241 to save energy.

[0087] In summary, the refrigerator 100 provided by the present application controls the flow direction of the refrigerant according to the ice quantity information in the ice storage box 132 when the refrigerator 100 is powered on after being powered off. When ice cubes are stored in the ice storage box 132, cold air is supplied to the ice making chamber 130 first, so as to prevent the ice cubes in the ice storage box 132 from melting too much, and the melted water from flowing out of the refrigerator 100 to the outside, causing damage to the refrigerator 100, and causing safety hazards, affecting the user experience. When there are no ice cubes stored in the ice storage box 132, cold air can be supplied to the storage room first, reducing the risk of damage to the food in the storage room.
