DETAILED DESCRIPTION

[0031] The embodiments of the present disclosure are described in detail below.

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, which should not be understood as a limitation to the present disclosure.

[0032] A refrigerator and a method and device for controlling refrigeration of a refrigerator according to embodiments of the present disclosure are described below with reference to the drawings.

[0033] Fig. 1 is a block diagram of a refrigeration system that can be implemented in a method for controlling refrigeration of a refrigerator according to an embodiment of the present disclosure. As shown in Fig. 1, the refrigeration system at least includes a compressor, a condenser, a control valve, a refrigerating capillary tube, an ice-making capillary tube, a refrigerating evaporator, an ice-making evaporator and an air return pipe. Among them, the compressor is connected to the condenser, the condenser is connected to the control valve, the control valve is respectively connected to the refrigerating capillary tube and the ice-making capillary tube, the refrigerating capillary tube is connected to the refrigerating evaporator, the ice-making capillary tube is connected to the ice-making evaporator, the ice-making evaporator is connected to the compressor through the air return pipe, and the refrigerating evaporator is connected to the ice-making evaporator. Among them, the refrigerating evaporator is configured to refrigerate the refrigerating compartment in the refrigerator, and the ice-making evaporator is configured to make ice in the ice machine, that is, for making ice in an ice-making compartment. The control valve is configured to control switching on or switching off a connecting direction to the refrigerating capillary tube and the ice-making capillary tube.

[0034] Fig. 2 is a block diagram of a refrigeration system that can be implemented in a method for controlling refrigeration of a refrigerator according to an embodiment of the present disclosure. As shown in Fig. 2, the refrigeration system in Fig. 2 differs from that in Fig. 1 in that the refrigerating evaporator in this refrigeration system is not connected to the ice-making evaporator but is connected to the compressor through the air return pipe.

[0035] It should be noted that the ice machine in the embodiments of the present disclosure can be located but not limited to, in a refrigerating compartment or a freezing compartment of the refrigerator, and the specific location can be determined according to actual conditions.

[0036] Fig. 3 is a schematic flow chart of a method for controlling refrigeration of a refrigerator according to an embodiment of the present disclosure. As shown in Fig. 3, the method for controlling refrigeration of a refrigerator in this embodiment includes the following steps.

S1. Recognizing a current ice-making stage of the ice machine

[0037] It should be noted that, in this embodiment, the ice-making stage of the ice machine includes two stages, i.e., a heating-deicing stage and a first ice-making stage. Among them, during the heating-deicing stage, a heating wire in the ice machine works to melt part of ice cubes, thereby causing the ice cubes to fall off. During the first ice-making stage, the ice-making evaporator works to decrease the temperature of the ice-making compartment, so that the liquid solidifies into a solid. It should be understood that the ice-making stage of the ice machine may be referred to as an ice-making mode, and the non-ice-making stage of the ice machine may be referred to as a non-ice-making mode to facilitate describing and distinguishing the ice-making stage and the non-ice-making stage. Optionally, it is possible to detect and determine that the ice machine is currently operating in an ice-making mode, before recognizing a current ice-making stage of the ice machine. Specifically, when detecting if the ice machine is operating in an ice-making mode, for example, a user's interactive interface or working mode selection button may be provided on the refrigerator, that the ice machine is currently operating in an ice-making mode can be determined by user according to the user's interactive interface or working mode selection button on the refrigerator. If the user selects the ice-making mode through the user's interactive interface, it is determined that the ice machine is currently operating in an ice-making mode. Optionally, the working mode can be selected through voice or remote control. When the ice-making mode is selected through voice or remote control, it can be determined that the ice machine is currently operating in an ice-making mode.

[0038] During the heating-deicing stage in the ice-making mode, a heating wire in the ice machine need to work to increase the temperature, to cause the solidified ice cubes to fall off. Thus, the current operating power of the refrigerator would be greater than the normal operating power of the refrigerator under the action of heating wire working. Thereby, in embodiments of the present disclosure, the current ice-making stage in the ice-making mode can be determined according to the current operating power of the refrigerator.

[0039] In the actual working process of the refrigerator, the operating power during the heating-deicing stage (hereinafter referred to as the "first power") is greater than the refrigerating power of the ice-making compartment alone in the refrigerator, but it is less than the refrigerating power of both the ice-making compartment and the refrigerating compartment in the refrigerator (hereinafter referred to as the "first power"). Thus, during the heating-deicing stage, when the refrigerator simultaneously performs the refrigeration of refrigerating compartment, the operating power of the refrigerator (hereinafter referred to as the "third power" for convenience of description) would be greater than the second power due to the large power of heating wire in the ice machine. As shown in Fig. 4, line 1 shows the change of temperature in the refrigerating compartment, line 2 shows the change of temperature in the ice-making compartment, and line 3 shows the change of operating power of the refrigerator. Among them, in the time period from 0 to t1, the refrigerating compartment does not perform refrigeration but the ice-making mode is in the heating-deicing stage; in the time period from t1 to t2, the refrigerating compartment performs refrigeration and the ice-making mode is in the heating-deicing stage; in the time period from t2 to t3, the refrigerating compartment continues refrigeration but the ice-making mode turns to an ice-making stage; and in the time period from t3 to t4, the refrigerating compartment stops refrigeration and the ice-making mode keeps in the ice-making stage until the ice-making stage ends. In the entire ice-making mode, the operating power P during the heating-deicing stage is within the range of the first power P1 to the second power P2. Thus, whether the ice-making mode is in the heating-deicing stage can be determined according to the operating power of the refrigerator. If the ice-making mode is not in the heating-deicing stage, it is in a first ice-making stage.

[0040] Optionally, after the ice machine is determined to be operated in the ice-making mode, a current temperature of the heating wire in the ice machine can be detected, thereby determining the current temperature of the heating wire. If the current temperature of the heating wire is higher than the preset temperature, it indicates that the ice machine is currently in the heating-deicing stage of the ice-making mode.

S2. Acquiring a current temperature of an ice-making compartment in the refrigerator

[0041] Specifically, a temperature sensor may be provided in the ice-making compartment in the refrigerator, to detect the current temperature of the ice-making compartment.

S3. Controlling a connecting direction of the control valve according to the current ice-making stage and the current temperature

[0042] According to the current ice-making stage of the ice-making mode and the current temperature in the ice-making compartment acquired, the connecting direction of the control valve can be controlled to determine whether the refrigerating compartment is to be refrigerated. Through controlling the refrigeration period of the refrigerating compartment, the refrigeration cycle of the refrigerating compartment matches the ice-making cycle of the ice-making compartment, thus reducing the influence of the refrigeration in the refrigerating compartment on the ice-making in the ice machine, improving the ice-making efficiency and ice-making amount, shortening the ice-making cycle, and reducing the energy consumption of the refrigerator.

[0043] It should be noted that, referring to Fig. 5, in an ideal state, as shown in Fig. 5a, the refrigeration cycle of the refrigerating compartment is same as the refrigeration cycle of the ice-making compartment. At the time, the ice-making efficiency of the ice machine is the highest, the ice-making amount is the highest and the energy consumption of the refrigerator is the lowest. Among them, during the time period from 0 to t1, the refrigerating compartment is in a refrigeration stage and the ice-making compartment is in a heating-deicing stage; during the time period from t1 to t2, the refrigerating compartment ends refrigerating, the ice-making compartment starts into the first ice-making stage, and making ice begins. However, in a practical application, since the refrigeration cycle of the refrigerating compartment is often shorter than the ice-making cycle of the ice-making compartment, the situation shown in Fig. 5b often occurs during the operation of the refrigerator, thereby generally resulting in the refrigerating compartment being in a refrigeration stage and the ice-making compartment being in a first ice-making stage. At the time, due to the amount of refrigerant splitting, the temperature of the ice-making evaporator rises, despite still lower than the preset temperature, resulting in slow down of the decrease of temperature of the ice-making compartment, decreasing the ice-making rate, increasing the ice-making cycle, reducing the ice-making amount and increasing the energy consumption. In addition, even when the starting refrigeration time of the refrigerating compartment keeps path with the heating-deicing time of the ice-making compartment, the situation shown in Fig. 5c occurs, resulting in that the ice-making compartment is still in the late stage of the heating-deicing stage when the refrigerating compartment begins in a refrigeration stage again. Meanwhile, due to the amount of refrigerant splitting, the temperature of the ice-making evaporator rises, despite still lower than the preset temperature, which would slow down the decrease of temperature of the ice-making compartment, decrease the ice-making rate, increase the ice-making cycle, reduce the ice-making amount, and increase the energy consumption. However, in the embodiments of the present disclosure, through controlling the refrigeration period of the refrigerating compartment and controlling the starting refrigeration time of the refrigerating compartment to be within a heating-deicing stage of ice-making mode of the ice-making compartment, the refrigeration cycle of the refrigerating compartment matches the ice-making cycle of the ice-making compartment, thereby forming the cycles as shown in Fig. 5d, thus greatly reducing the time period when both the refrigerating compartment and the ice-making compartment perform refrigerating, thereby reducing the influence of refrigeration in the refrigerating compartment on ice-making in the ice-making compartment, improving the ice-making efficiency and ice-making amount, shortening the ice-making cycle, and reducing the energy consumption of the refrigerator.

[0044] Above all, the present invention proposes a method for controlling refrigeration of a refrigerator. The method controls the connecting direction of the control valve in the refrigeration system of the refrigerator according to the current ice-making stage of the ice machine and the current temperature of the ice-making compartment. Through controlling the connecting direction of the control valve to determine the time of performing refrigeration and the time of ending refrigeration for corresponding compartments, the refrigeration period of the refrigerating compartment is controlled and the starting refrigeration time of the refrigerating compartment is controlled to be within a heating-deicing stage of ice-making mode of the ice-making compartment, such that the refrigeration cycle of the refrigerating compartment matches the ice-making cycle of the ice-making compartment, thus improving the ice-making efficiency of the ice machine and the ice-making amount, shortening the ice-making cycle, and reducing the energy consumption of the refrigerator.

[0045] In some embodiments, the time of performing refrigeration in the refrigerating compartment can be determined according to the temperature in the ice-making compartment. Fig. 6 is a schematic flow chart of a process for controlling a starting refrigeration time of the refrigerating compartment in a method for controlling refrigeration of a refrigerator according to the present disclosure. As shown in Fig. 6, the method includes the following steps.

S61. Detecting and determining that the current ice-making stage is a heating-deicing stage

[0046] Specifically, if the refrigerator is in the heating-deicing stage can be determined according to the current operating power of the refrigerator. Referring to the description in step S1, if the current operating power of the refrigerator is between the first power and the second power, it indicates that the current ice-making stage is a heating-deicing stage.

S62. Detecting and determining that the current temperature is greater than a first preset temperature threshold

[0047] It should be noted that a first preset temperature threshold is preset in the refrigerator, and whether the refrigeration in the refrigerating compartment is initiated can be determined according to the temperature in the ice-making compartment and the first preset temperature threshold. In embodiments of the present disclosure, the first preset temperature threshold is set, and only when the temperature in the ice-making compartment is greater than the first preset temperature threshold, the refrigeration in the refrigerating compartment can be initiated, thereby capable of controlling the starting refrigeration time of the refrigerating compartment, such that the refrigeration cycle of the refrigerating compartment matches the ice-making cycle of the ice-making compartment.

[0048] Specifically, the current temperature of the ice-making compartment of the refrigerator is acquired and it can be compared with the first preset temperature threshold. Further, the magnitude relationship between the current temperature of the ice-making compartment of the refrigerator and the first preset temperature threshold can be determined. If the current temperature is greater than the first preset temperature threshold, step S63 is executed; otherwise, step S64 is executed.

S63. Controlling the control valve to switch on the connecting direction to the refrigerating capillary tube.

[0049] When the current temperature is greater than the first preset temperature threshold, the refrigeration of the refrigerating compartment is performed, that is, controlling the control valve to switch on the connecting direction to the refrigerating capillary tube. It should be understood that the control valve switches off the connecting direction to the ice-making capillary tube at this time.

S64. Controlling the control valve to switch off

[0050] Specifically, if the current temperature is less than or equal to the first preset temperature threshold, the control valve switches off, that is, the refrigeration system stops refrigerating, thereby controlling the starting refrigeration time of the refrigerating compartment.

[0051] In some embodiments, considering that the simultaneous refrigeration of the refrigerating compartment and the refrigerating compartment for a long time would reduce the ice-making efficiency and increase the energy consumption, the refrigeration ending period of the refrigerating compartment can also be controlled to avoid occurrence of the above situation. Specifically, referring to Fig. 7, Fig. 7 is a schematic flow chart of a process for improving ice-making efficiency in a method for controlling refrigeration of a refrigerator according to an embodiment of the present disclosure. As shown in Fig. 7, the method includes the following steps.

S71. Detecting and determining that the current ice-making stage is a first ice-making stage

[0052] Specifically, whether the heating-deicing stage ends can be detected. When the heating-deicing stage ends, it indicates that the current ice-making stage is in the first ice-making stage.

[0053] S72. Detecting and determining that the second current temperature of the refrigerating compartment is greater than a second preset temperature threshold.

[0054] It should be noted that a second preset temperature threshold is preset in the refrigerator. Whether the refrigeration in the refrigerating compartment ends can be determined according to the temperature in the ice-making compartment and the second preset temperature threshold. The setting of the second preset temperature threshold prevents the refrigerating compartment and the ice-making compartment from simultaneously refrigerating for a long time, thus not only reducing energy consumption and improving ice-making efficiency, but also meeting the refrigeration requirements of the refrigerating compartment. For example, if the target temperature set in the refrigerating compartment is lower than the second preset temperature threshold, the refrigeration of the refrigerating compartment is ended in advance to ensure ice-making efficiency; and if the target temperature set in the refrigerating compartment is greater than or equal to the second preset temperature threshold, the refrigeration of the refrigerating compartment can be ended when the target temperature is reached.

[0055] Specifically, the second current temperature of the refrigerating compartment of the refrigerator is acquired and it can be compared with the second preset temperature threshold. Further, the magnitude relationship between the second current temperature of the refrigerating compartment of the refrigerator and the second preset temperature threshold can be determined. If the second current temperature is greater than the second preset temperature threshold, step S73 is executed; otherwise, step S74 is executed.

S73. Controlling the control valve to switch on the connecting direction to both the refrigerating capillary tube and the ice-making capillary tube

[0056] Specifically, if the second current temperature of the refrigerating compartment is greater than the second preset temperature threshold, the control valve is controlled to switch on the connecting direction to both the refrigerating capillary tube and the ice-making capillary tube, thus performing the refrigeration in both the ice-making compartment and the refrigerating compartment.

S74. Controlling the control valve to switch off the connecting direction to the refrigerating capillary tube

[0057] Specifically, if the second current temperature of the refrigerating compartment is less than or equal to the second preset temperature threshold, the control valve is controlled to switch off the connecting direction to the refrigerating capillary tube, thus ending the refrigeration in the refrigerating compartment.

[0058] It should be understood that, in this embodiment, the method needs to acquire a refrigeration request instruction issued by either the refrigerating compartment or the ice-making compartment before controlling a connecting direction of the control valve, and select the connecting direction to be switched on by the control valve according to the corresponding refrigeration request instruction.

[0059] In some embodiments, if the ice machine is currently operating in a non-ice-making mode, the connecting direction of the control valve can be controlled according to the following steps. As shown in Fig. 8, the method includes steps.

S81. Detecting and determining that the ice machine is currently operating in a non-ice-making mode

[0060] Specifically, referring to the description in step S1 as above, if the ice machine is not in the ice-making mode, it is determined that the ice machine is currently operating in a non-ice-making mode.

S82. Detecting a refrigeration request instruction issued by either the refrigerating compartment or the ice-making compartment

[0061] Specifically, during the operation of the refrigerator, when the internal temperature of the refrigerator changes, compartments like the refrigerating compartment, the ice-making compartment and the like are to be refrigerated from time to time. When a corresponding compartment needs to be refrigerated, the corresponding compartment will issue a refrigeration request instruction to request being refrigerated by the refrigerator. Thus, the refrigeration request instruction issued by respective compartment can be detected in real time or at intervals.

S83. Controlling the connecting direction of the control valve according to the detected refrigeration request instruction and a source of the refrigeration request instruction

[0062] Specifically, the connecting direction of the control valve is controlled according to the refrigeration request instruction issued by corresponding compartments. For example, if the ice-making compartment and the refrigerating compartment both issue a refrigeration request instruction, the control valve would switch on the connecting direction to both the refrigerating capillary tube and the ice-making capillary tube. If the ice-making compartment issues a refrigeration request instruction but the refrigerating compartment does not issue a refrigeration request instruction, the control valve would switch on the connecting direction to the ice-making capillary tube but would switch off the connecting direction to the refrigerating capillary tube.
