In the refrigeration process, the compressor 210 starts to compress the refrigerant, 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 flows through the ice-making refrigerant branch 230 formed by the ice-making capillary tube and the ice-making evaporator 231 after passing through the refrigerant control valve 220 and then returns to the compressor 210, and correspondingly, if the tank refrigerant outlet of the refrigerant control valve 220 is opened, the refrigerant flows through the tank refrigerant branch 240 formed by the tank capillary tube and the tank evaporator after passing through the refrigerant control valve 220 and then returns to the compressor 210.
In an embodiment of the present invention, the tank evaporator 241 may include two independent evaporators respectively corresponding to the refrigerating compartment 111 and the freezing compartment 112, and the tank refrigerant outlet of the refrigerant control valve 220 may include two refrigerant outlets respectively corresponding to the two evaporators.
In an embodiment of the present invention, the refrigerator 100 further includes a control module, which may be configured to:
when a power-on signal of the refrigerator 100 is received, 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 box body temperature sensor are obtained;
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 be started, and the ice amount information detected by the ice amount detection module is acquired, if the ice amount of the ice storage box is greater than the preset value, the ice making refrigerant outlet is controlled to be opened by the refrigerant control valve 220 first, and when the temperature of the ice making chamber 130 reaches the preset ice making refrigeration system shutdown temperature, the ice making refrigerant outlet is controlled to be closed by the refrigerant control valve 220, wherein the first preset temperature is greater than or equal to the preset tank refrigeration system shutdown temperature, and the second preset temperature is greater than or equal to the preset ice making refrigeration system shutdown temperature.
In this embodiment, the first preset temperature is less than or equal to a preset starting temperature of the box refrigeration system, and the second preset temperature is less than or equal to a preset starting temperature of the ice-making refrigeration system. The starting temperature of the ice making and refrigerating system and the starting temperature of the box refrigerating system are preset temperatures, wherein when the refrigerator normally operates and the temperature of the ice making compartment 130 is higher than the starting temperature of the ice making and refrigerating system, it can be determined that the temperature in the ice making compartment 130 is higher, which may affect the operation of the ice making device 131 and the storage of ice cubes in the ice storage box 132, and at this time, the refrigerating system 200 needs to be started to supply cold air to the ice making compartment 130. Similarly, when the temperature of storing compartment was greater than box refrigerating system start temperature, can judge that the indoor high temperature in storing compartment influences the storage of eating the material, need open refrigerating system 200 and supply cold air for storing compartment.
In addition, the refrigerator 100 is preset with an ice-making and refrigerating system shutdown temperature, and when the refrigerating 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 and refrigerating system shutdown temperature, it may be determined that the temperature of the ice-making compartment 130 reaches a temperature at which the ice-making compartment can normally operate, and the ice-making evaporator 231 may not be supplied with refrigerant any more to stop refrigerating the ice-making compartment 130. Similarly, during the cooling of the storage compartment, if the temperature of the storage compartment drops to the shutdown temperature of the corresponding cabinet cooling system, the supply of refrigerant to the cabinet evaporator 241 may be stopped to stop the supply of cool air to the storage compartment.
In this embodiment, when the refrigerator is powered on, the compressor can be started to refrigerate when the temperature of the storage compartment is higher than the shutdown temperature of the corresponding box refrigeration system or the temperature of the ice-making compartment is higher than the shutdown temperature of the corresponding ice-making refrigeration system, so that the temperature of the compartment is quickly reduced, and the negative effects caused by power failure are reduced.
In the present embodiment, if the refrigerating compartment 111 and the freezing compartment 112 share one case evaporator 241, the supply of the refrigerant to the case evaporator 241 may be stopped when both the temperatures in the refrigerating compartment 111 and the freezing compartment 112 decrease to the corresponding refrigeration system shutdown temperatures, and if only one of the temperatures reaches the corresponding refrigeration system shutdown temperature, the supply of the cool air may be blocked by controlling the corresponding air supply fan and the air door to be closed.
In the present embodiment, since the ice making evaporator 231 and the cabinet evaporator 241 share one compressor 210, in order to secure the refrigeration system 200 and to facilitate control, a refrigerant is often supplied to only one evaporator during the refrigeration process. If the refrigerator 100 is powered on after power off and only the ice making compartment 130 or the storage compartment needs to be cooled, the refrigerant control valve 220 is controlled to open the corresponding refrigerant outlet to supply the refrigerant to the corresponding evaporator.
When the refrigerator 100 is powered on after power off, if the ice making compartment 130 and the storage compartment need to be cooled, the flow direction of the refrigerant can be controlled according to the information of the amount of ice in the ice bank 132. If the amount of ice in the ice bank 132 is greater than the preset value, the refrigerant control valve 220 may 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.
The preset value can be 0 or other values, and when the preset value is 0, whether ice is stored in the ice storage box or not is detected.
After the ice making refrigerant outlet is opened by the control refrigerant control valve 220, the ice making refrigerant outlet can be continuously opened or periodically and intermittently opened, and when the temperature of the ice making chamber reaches the preset shutdown temperature of the ice making refrigeration system, the control refrigerant control valve can be controlled to continuously close the ice making refrigerant outlet until the temperature of the ice making chamber is higher than the startup temperature of the ice making refrigeration system or other conditions needing to refrigerate the ice making chamber occur.
In this way, when the refrigerator 100 is powered on after power off, if ice cubes are stored in the ice bank 132, cold air is preferentially supplied to the ice making compartment 130, so that it is prevented that the ice cubes in the ice bank 132 are excessively melted and the melted liquid water flows out of the refrigerator 100 through a structure such as an ice outlet pipe of the dispenser 123, which may affect user experience.
Further, in the first embodiment provided by the present invention, the control module is specifically configured to:
if the ice amount of the ice storage box is greater than the 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 compartment 130 reaches the preset ice-making and 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.
In this embodiment, when the refrigerator 100 is powered off and then powered on again, if ice is still stored in the ice storage bin 132, the refrigerant control valve 220 is controlled to continuously open the ice making refrigerant outlet corresponding to the ice making evaporator 231, and when the temperature of the ice making compartment 130 is preferentially reduced to the shutdown temperature of the ice making and refrigerating system corresponding to the ice making compartment 130, the box refrigerant branch 240 corresponding to the box evaporator 241 is controlled to be opened to refrigerate the storage compartment.
In this way, control can be simplified, switching of the refrigerant control valve 220 can be reduced, and the ice making compartment 130 can be cooled quickly.
Further, in this embodiment, the control module is further configured to:
if the ice amount of the ice storage 132 is greater than the preset value, the compressor 210 is controlled to be turned off when the temperature of the storage compartment reaches the shutdown temperature of the box refrigeration system and the temperature of the ice making compartment 130 is less than the second preset temperature.
In this embodiment, if ice is stored in the ice bank 132, the ice making compartment 130 is cooled first and then the storage compartment is cooled, and when the temperature of the storage compartment drops to the shutdown temperature of the corresponding box refrigeration system, the supply of refrigerant to the box evaporator 241 and thus the supply of cold air to the ice making compartment 130 may be stopped. If the temperature of the ice making compartment 130 is lower than the second preset temperature, the compressor 210 may be turned off, the refrigeration may be stopped, and the temperature of the ice making compartment 130 and the temperature of the storage compartment may be continuously monitored, and when the temperature of the ice making compartment 130 is higher than the corresponding start-up temperature of the ice making refrigeration system or the temperature of the storage compartment is higher than the corresponding start-up temperature of the box refrigeration system, the compressor 210 may be controlled to be turned on again, and the refrigerant control valve 220 may be controlled to open the corresponding refrigerant opening to supply the refrigerant to the corresponding evaporator, thereby supplying cold air to the corresponding compartment.
Further, in an embodiment of the present invention, the control module is further configured to:
if the amount of ice in the ice storage bin 132 is less than the preset value, the refrigerant control valve 220 is controlled to open the refrigerant outlet of the tank first, and when the temperature of the storage compartment reaches the preset shutdown temperature of the refrigeration system of the tank, the refrigerant control valve 220 is controlled to close the refrigerant outlet of the tank.
In this embodiment, if the refrigerator 100 is powered on again after power off, it is detected that no ice cubes are stored in the ice bank 132 or the amount of stored ice is small, at this time, the amount of melted ice cubes is small, and the melted water flows into the water receiving tray 124 from the ice bank and then does not overflow the water receiving tray 124.
In this embodiment, the control module may be specifically configured to:
if the ice amount is less than the preset value, the refrigerant control valve 220 is controlled to continuously open the refrigerator body refrigerant outlet, and when the temperature of the storage compartment reaches the preset shutdown temperature of the refrigerator body refrigeration system, the refrigerant control valve 220 is controlled to close the refrigerator body refrigerant outlet and open the ice making refrigerant outlet.
The control module is further configured to: when the temperature of the ice making chamber 130 reaches the corresponding shutdown temperature of the ice making and refrigerating system and the temperature of the storage chamber is lower than the corresponding first preset temperature, the compressor 210 is controlled to be turned off.
In this embodiment, when the refrigerator 100 is powered on again after power off, if no ice cubes are stored in the ice storage 132 or the amount of ice is small, the refrigerant may be controlled to be continuously supplied to the box evaporator 241, when the temperature of the box 110 reaches the shutdown temperature of the corresponding box refrigeration system, the refrigerant may be continuously supplied to the ice making evaporator 231 corresponding to the ice making compartment 130 until the temperature in the ice making compartment 130 is reduced to the shutdown temperature of the ice making refrigeration system, and if the temperature in the storage compartment is still less than the first preset temperature, the refrigeration is finished, the compressor 210 may be turned off, and the temperatures in the ice making compartment 130 and the storage compartment may be continuously monitored. Therefore, switching of the refrigerant control valve 220 can be reduced, and rapid refrigeration can be performed in the storage chamber.
In a second embodiment, the difference between the first embodiment and the second embodiment is mainly that the control module is specifically configured to:
if the ice amount of the ice storage box 132 is smaller than the preset value, the refrigerant control valve 220 is controlled to periodically open the box refrigerant outlet for a third preset time period first, then close the box refrigerant outlet and open the ice making refrigerant outlet for a fourth preset time period, wherein the third preset time period is longer than the fourth preset time period;
when the temperature of the storage compartment reaches the preset shutdown temperature of the box body refrigerating system, controlling the refrigerant control valve 220 to continuously close the box body refrigerant outlet and continuously open the ice-making refrigerating outlet;
and controls the compressor 210 to be turned off when the temperature of the ice-making compartment 130 reaches the ice-making and refrigeration system shutdown temperature.
In this embodiment, if the ice amount in the ice bank 132 is less than the preset value and the risk of water overflowing the water tray 124 due to ice melting in the ice bank is low, the refrigerant control valve 220 may be controlled to alternately open the tank refrigerant outlet and the ice making refrigerant outlet, and the opening duration of the tank refrigerant outlet is longer than that of the ice making refrigerant outlet, so as to preferentially cool the storage compartment and ensure that the articles in the storage compartment are not damaged.
When the refrigerant control valve 220 opens the tank refrigerant outlet for a third predetermined time, the volume of the refrigerant in the tank evaporator 241 is equal to the capacity of the tank evaporator 241, and at this time, the tank evaporator 241 reaches the maximum cooling capacity, and if the refrigerant continues to be supplied to the tank evaporator 241 at this time, energy is wasted. In this way, the refrigerator refrigerant outlet and the ice-making refrigerant outlet are alternately opened to alternately supply the refrigerant to the refrigerator evaporator 241 and the ice-making evaporator 231, so that energy can be reasonably utilized and energy consumption can be reduced.
The present invention also provides a third embodiment, which is an improvement of the refrigerator 100 of the first embodiment or the second embodiment, and the difference is mainly that, compared with the first embodiment or the second embodiment, in the present embodiment, the control module configuration is specifically configured to:
if the amount of ice in the ice bank 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 period first, then close the ice-making refrigerant outlet and open the tank refrigerant outlet for a second preset time period, wherein the first preset time period is greater than the second preset time period.
The control module is further configured to:
when the temperature of the ice making compartment 130 reaches the preset shutdown temperature of the ice making and refrigerating system, the ice making agent control valve is controlled to continuously close the ice making refrigerant outlet and continuously open the box body refrigerant outlet.
In the present embodiment, in order to make reasonable use of energy, the refrigerant is periodically supplied to the ice making evaporator 231 and the case evaporator 241, the refrigerant is supplied to the ice making evaporator 231 first, and a large amount of refrigerant is supplied to the ice making evaporator 231 to perform preferential cooling of the ice making compartment 130. When the temperature of the ice making compartment 130 reaches the corresponding ice making and refrigerating system shutdown temperature, the supply of the refrigerant to the ice making evaporator 231 may be stopped, and at this time, the supply of the refrigerant to the case evaporator 241 may be continued.
In the present embodiment, when the ice making refrigerant outlet is opened for the first predetermined time, the volume of the refrigerant in the ice making evaporator 231 may be equal to the capacity of the ice making evaporator 231, and at this time, the ice making evaporator 231 reaches the maximum cooling capacity, and if the supply of the refrigerant to the ice making evaporator 231 is continued, energy is wasted. Therefore, at this time, the supply of the refrigerant to the ice making evaporator 231 may be stopped and the refrigerant may be supplied to the case evaporator 241 to save power consumption.
