A refrigerator and a method and device for controlling refrigeration of a refrigerator

Fig. 2 is a block diagram of a refrigeration system that can be implemented in a method for

shown in Fig. 2, the refrigeration system in Fig. 2 differs from that in Fig. 1 in that the

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.
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.
Si. Recognizing a current ice-making stage of the ice machine
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.
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.
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 tl, the refrigerating
compartment does not perform refrigeration but the ice-making mode is in the heating-deicing
stage; in the time period from t 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 P Ito 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.
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
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
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.
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 ti, the refrigerating compartment is in a
refrigeration stage and the ice-making compartment is in a heating-deicing stage; during the time
period from ti 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 the
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.
Above all, the present disclosure in embodiments 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.
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 an
embodiment of 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
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 Si, 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
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.
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
Specifically, 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
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.
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
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.
S72. Detecting and determining that a second current temperature of the refrigerating compartment is greater than a second preset temperature threshold
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.
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
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
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.
It should be understood that, in this embodiment, the method needs to acquire a refrigeration
request instruction issued by at least one of the refrigerating compartment and 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.
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
Specifically, referring to the description in step Sias 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 at least one of the refrigerating
compartment and the ice-making compartment
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 refrigeration
request instruction detected and a source of the refrigeration request instruction
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.

to Fig. 4 showing the schematic diagram of the refrigeration cycle of refrigerating compartment
