Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A refrigerator and a cooling control method and apparatus thereof according to embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a system architecture diagram in which a refrigeration control method of a refrigerator according to an embodiment of the present disclosure can be implemented. As shown in fig. 1, the refrigeration system includes at least one compressor, a condenser, an evaporator, an ice making damper, a refrigeration damper, and a return air pipe. Wherein, the compressor links to each other with the condenser, and the condenser links to each other with the evaporimeter, and the evaporimeter links to each other with ice-making air door and cold-stored air door respectively, and ice-making air door and cold-stored air door link to each other with the compressor through the muffler respectively. The evaporator is used for refrigerating the refrigerating chamber in the refrigerator and making ice for the ice machine. The opening and closing of the ice making air door and the refrigerating air door are controlled, so that whether the ice making chamber and the refrigerating chamber are refrigerated or not can be realized.
It should be noted that the ice maker in the embodiment of the present invention is located in the freezer compartment of the refrigerator.
Fig. 2 is a flowchart illustrating a refrigeration control method of a refrigerator according to an embodiment of the disclosure. As shown in fig. 3, the refrigeration control method of the refrigerator in the embodiment includes the following steps:
and S1, identifying the current ice making stage of the ice machine.
It should be noted that, in this embodiment, the ice making stage of the ice maker includes two stages, i.e., heating for ice removal and the first ice making. During the heating and ice-removing stage, a heating wire in the ice maker does work to partially melt the ice cubes so as to enable the ice cubes to fall off; in the first ice making stage, the ice making evaporator operates to lower the temperature in the ice making compartment and to solidify the liquid into a solid. It should be understood that for ease of description and to distinguish between the ice making phase and the non-ice making phase, the ice making phase of the ice maker may be referred to as the ice making mode and the non-ice making phase as the non-ice making mode.
Alternatively, before identifying the ice making stage in which the ice maker is currently located, it may be detected and determined that the refrigerator is currently operating in the ice making mode. Specifically, whether the ice maker operates in the ice making mode is detected, for example, an interactive interface or a working mode selection key of a user can be arranged on the refrigerator, and when the current working mode of the refrigerator is determined, the judgment can be performed according to a function key selected by the user through the interactive interface or the working mode on the refrigerator; and if the user selects the ice making mode through the user interaction interface, determining that the ice making machine operates in the ice making mode currently. Optionally, the operation mode may be selected by voice or remote control, and when the ice making mode is selected by voice or remote control, it may be determined that the ice making machine is currently operating in the ice making mode.
In the heating and deicing stage in the ice making mode, the heating wire in the ice making machine is required to do work to raise the temperature so as to shed the condensed ice, so that the current running power of the refrigerator is greater than the power of the refrigerator in normal running under the action of the working of the heating wire.
During the actual operation of the refrigerator, the operation power of the heating and deicing stage is larger than the power of the refrigerator for refrigerating the ice making compartment alone (hereinafter referred to as "first power"), but is smaller than the power of the refrigerator for refrigerating the ice making compartment and the refrigerating compartment simultaneously (hereinafter referred to as "second power"). In addition, because the power of the heating wire in the ice maker is larger, the running power of the refrigerator is larger than the second power when the refrigerator simultaneously refrigerates the cold storage chamber in the heating and deicing stage, and for convenience of description, the power of the refrigerator at this time is called as the third power. As shown in fig. 3, line 1 represents the temperature change in the refrigerating compartment, line 2 represents the temperature change in the ice-making compartment, and line 3 represents the operating power change of the refrigerator. Wherein, in the time period of 0-t 1, the refrigerating chamber is not refrigerated, and the ice making mode is in the heating and ice removing stage; in the time period of t 1-t 2, the refrigerating chamber starts to refrigerate, and the ice making mode is in a heating and ice removing stage; in the time period from t2 to t3, the refrigerating chamber continues to refrigerate, and the ice making mode enters an ice making stage; and (4) stopping refrigerating the refrigerating chamber in the time period of t 3-t 4, and keeping the ice making stage in the ice making mode until the stage is finished. In the whole ice making mode, the operation power P of the heating deicing phase is in the interval range of the first power P1 and the second power P2; therefore, it may be determined whether the ice making mode is in the heating and de-icing stage according to the operation power of the refrigerator, and if the ice making mode is not in the heating and de-icing stage, it is in the first ice making stage.
Optionally, after it is determined that the ice maker operates in the ice making mode, the current temperature of the heating wire in the ice maker may be detected, and then the current temperature of the heating wire is determined, and if the current temperature of the heating wire is higher than a preset temperature, it indicates that the ice maker is in a heating and ice-shedding stage in the ice making mode at present.
And S2, acquiring the current temperature of the ice making compartment in the refrigerator.
Specifically, a temperature sensor may be provided in the ice making compartment in the refrigerator, and the current temperature of the ice making compartment may be detected by the temperature sensor.
And S3, controlling the opening and closing of the ice making damper and the cold storage damper according to the current ice making stage and the current temperature.
The current ice making stage of the ice making mode and the current temperature in the ice making compartment are obtained, and the ice making damper and the cold storage damper can be controlled to determine whether the corresponding compartment is refrigerated or not. Furthermore, the opening time of the cold storage air door is controlled, the refrigerating time period of the cold storage chamber is controlled, and the refrigerating cycle of the cold storage chamber is matched with the ice making cycle of the ice making chamber. Furthermore, the influence of refrigeration of the cold storage chamber on ice making of the ice making machine is reduced, the ice making efficiency and the ice making quantity are improved, the ice making period is shortened, and the energy consumption of the refrigerator is reduced.
It should be noted that, referring to fig. 4, ideally, as shown in fig. 4a, the refrigeration cycle of the refrigerating compartment is the same as that of the ice making compartment, at this time, the ice making efficiency of the ice making machine is the highest, the ice making amount is the highest, and the energy consumption of the refrigerator is the lowest, where in the graph, the refrigerating compartment is in the refrigeration stage and the ice making compartment is in the heating and deicing stage within a time period of 0 to t 1; and in the time period of t 1-t 2, the refrigeration of the refrigerating chamber is finished, the ice making chamber enters a first ice making stage, and ice making is started. However, in practical applications, since the refrigeration cycle of the refrigeration compartment is often smaller than the ice-making cycle of the ice-making compartment, in the operation process of the refrigerator, as shown in fig. 4b, it often occurs that the refrigeration compartment is in the refrigeration stage, the ice-making compartment is in the first ice-making stage, at this time, the temperature of the refrigeration evaporator rises due to the diversion of the refrigerant quantity, and although the temperature is still lower than the preset temperature, the temperature of the ice-making compartment drops and becomes slow, the ice-making rate drops, the cycle becomes long, the ice-making quantity drops and the energy consumption increases. In addition, when the time when the refrigerating compartment starts to refrigerate is the same as the time when the ice making compartment heats the ice removing section, the situation as shown in fig. 4c may occur, which may cause the ice making compartment to be in the later stage of the first ice making stage when the refrigerating compartment is in the refrigerating stage again, and at this time, the temperature of the refrigeration evaporator may rise due to the refrigerant amount diversion, and although the temperature is still lower than the preset temperature, the temperature of the ice making compartment may fall slowly, the ice making rate may fall, the cycle may be lengthened, the ice making amount may fall, and the energy consumption may be increased. In the embodiment of the invention, the refrigeration time period of the refrigerating chamber is controlled, the time for starting refrigeration of the refrigerating chamber is delayed, and the time for starting refrigeration is set in the heating and ice-removing stage of the ice-making mode of the ice-making chamber, so that the refrigeration cycle of the refrigerating chamber is matched with the ice-making cycle of the ice-making chamber, and the cycles of the refrigerating chamber and the ice-making chamber are as shown in fig. 4d, thereby greatly reducing the time for refrigerating the refrigerating chamber and the ice-making chamber at the same time, reducing the influence of refrigeration of the refrigerating chamber on ice-making of the ice-making chamber, improving the ice-making efficiency and the ice-making quantity, shortening the ice-.
In summary, according to the refrigeration control method of the refrigerator provided by the embodiment of the present invention, the ice making damper and the cold storage damper in the refrigeration system of the refrigerator are controlled according to the current ice making stage of the ice maker and the current temperature of the ice making compartment. The time for refrigerating the corresponding compartment and the time for finishing the refrigeration are determined by controlling the ice making air door and the cold storage air door; furthermore, the refrigeration time interval of the refrigerating chamber is controlled, the time when the refrigerating chamber starts to refrigerate is delayed, and the time when the refrigerating chamber starts to refrigerate is set to the heating and ice-removing stage of the ice-making chamber ice-making mode, so that the refrigeration cycle of the refrigerating chamber is matched with the ice-making cycle of the ice-making chamber, the ice-making efficiency and the ice-making quantity of the ice-making machine are improved, the ice-making cycle is shortened, and the energy consumption of the refrigerator is reduced.
In some embodiments, the time for cooling the cold storage compartment may be determined based on the temperature in the ice making compartment. Fig. 5 is a schematic flowchart illustrating a method for controlling a time when a refrigerating compartment is opened for refrigeration in a refrigeration control method of a refrigerator according to an embodiment of the disclosure, as shown in fig. 5, the method includes the following steps:
and S51, detecting and determining that the current ice making stage is a heating and ice removing stage.
Specifically, whether the refrigerator is in the heating and deicing stage may be determined according to the current operating power of the refrigerator. Referring to the description of step S1, if the current operation power of the refrigerator is between the first power and the second power, it indicates that the current ice making stage is the heating and ice removing stage.
And S52, detecting and determining that the current temperature is greater than a first preset temperature threshold value.
It should be noted that a first preset temperature threshold is preset in the refrigerator, and whether to start refrigeration for the refrigerating compartment can be determined according to the temperature in the ice-making compartment and the first preset temperature threshold. In the embodiment of the invention, the first preset temperature threshold is set, and the refrigerating chamber can be started for refrigeration only when the temperature in the ice making chamber is larger than the first preset temperature threshold, so that the time for starting refrigeration of the refrigerating chamber can be delayed, and the refrigeration cycle of the refrigerating chamber is matched with the ice making cycle of the ice making chamber.
Specifically, the current temperature of the ice making compartment of the refrigerator is obtained, and then the current temperature may be compared with a first preset temperature threshold, and further, a magnitude relation between the current temperature and the first preset temperature threshold is determined. If the current temperature is greater than the first preset temperature threshold, executing step S53; otherwise, step S54 is executed.
And S53, controlling to open the refrigerating air door and close the ice making air door.
Specifically, when the current temperature is greater than a first preset temperature threshold value, the refrigerating chamber is refrigerated, namely, the refrigerating air door is controlled to be opened, and at the moment, the ice making air door is in a closed state.
And S54, controlling to close the ice making damper and the cold storage damper simultaneously.
Specifically, if the current temperature is less than or equal to the first preset temperature threshold, the ice making damper and the refrigerating damper are closed at the same time, that is, the system stops refrigerating, so that the refrigerating time of the refrigerating compartment is delayed.
In some embodiments, in order to avoid the above situation, the refrigeration end period of the refrigerating compartment may be controlled in consideration of the fact that the ice making efficiency is reduced and the energy consumption is increased when the ice making compartment and the refrigerating compartment are simultaneously refrigerated for a long time. Specifically, referring to fig. 6, fig. 6 is a schematic flowchart illustrating a method for improving ice making efficiency in a refrigeration control method of a refrigerator according to an embodiment of the disclosure, as shown in fig. 6, the method includes the following steps:
and S61, detecting and determining that the current ice making stage is the first ice making stage.
Specifically, whether the heating and deicing phase is finished or not can be detected, and when the heating and deicing phase is finished, it indicates that the current ice making phase is in the first ice making phase.
And S62, detecting and determining that the current temperature is greater than a second preset temperature threshold value.
It should be noted that a second preset temperature threshold is preset in the refrigerator, and whether to finish cooling the refrigerating compartment 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 value avoids the long-time simultaneous refrigeration of the ice making chamber and the cold storage chamber, so that the energy consumption can be reduced, the ice making efficiency is improved, and the refrigeration requirement of the cold storage chamber is met. For example, if the target temperature set in the refrigerating compartment is lower than a second preset temperature threshold, in order to ensure the ice making efficiency, the refrigeration of the refrigerating compartment is ended in advance; and if the target temperature set in the refrigerating chamber is greater than or equal to the second preset temperature threshold value, the refrigerating chamber can be finished when the target temperature is reached.
Specifically, the current temperature of the ice making compartment of the refrigerator is obtained, and then the current temperature can be compared with a second preset temperature threshold, and further, the size relationship between the current temperature and the second preset temperature threshold is determined. If the current temperature is greater than the second preset temperature threshold, executing step S63; otherwise, step S64 is executed.
And S63, controlling to open the ice making damper and the cold storage damper simultaneously.
Specifically, if the current temperature is greater than the second preset temperature threshold, the ice making air door and the cold storage air door are opened simultaneously, and the ice making chamber and the cold storage chamber are refrigerated simultaneously.
And S64, controlling to close the refrigerating air door.
Specifically, if the current temperature is less than or equal to the second preset temperature threshold, the refrigeration damper is controlled to be closed, namely, refrigeration of the refrigeration compartment is finished.
It should be understood that, in this embodiment, before controlling the opening and closing of the ice making damper and the cold storage damper, it is necessary to obtain a refrigeration instruction sent by at least one of the cold storage compartment and the ice making compartment, and open and close the ice making damper and the cold storage damper according to the corresponding refrigeration instruction.
In some embodiments, if the ice maker is currently operating in a non-ice making mode, the opening and closing of the ice making damper and the refrigeration damper may be controlled according to the following method. As shown in fig. 7, the method includes:
and S71, detecting and determining that the ice machine is operated in a non-ice making mode currently.
Specifically, referring to the description in step S1 above, if the ice maker is not in the ice making mode, it is currently operating in the non-ice making mode.
And S72, detecting a refrigeration instruction sent by at least one of the cold storage chamber and the ice making chamber.
Specifically, in the working process of the refrigerator, under the condition that the internal temperature of the refrigerator changes, the compartments such as a cold storage compartment and an ice making compartment can be cooled at irregular time, and when the corresponding compartment needs to be cooled, the corresponding compartment sends a request for cooling to request the refrigerator to cool. Therefore, the cooling commands sent in the respective compartments can be detected in real time or at intervals.
And S73, controlling the opening and closing of the ice making air door and the cold storage air door according to the detected refrigeration instruction and the source of the refrigeration instruction.
Specifically, the opening and closing of the ice making damper and the cold storage damper are controlled according to a refrigeration request instruction sent by the corresponding compartment. For example, if the ice making chamber and the refrigerating chamber send out refrigeration requests at the same time, the ice making damper and the refrigerating damper are opened at the same time; and if the ice making chamber sends a refrigeration request and the refrigerating chamber does not send the refrigeration request, the ice making air door is opened and the refrigerating air door is closed.
Fig. 8 is a control flowchart of a cooling control method of a refrigerator according to an embodiment of the present disclosure. As shown in fig. 8, the control flow of the refrigeration control method for the refrigerator according to the embodiment of the present invention includes the following steps:
and S81, detecting whether the ice maker is in an ice making mode. If yes, go to step S82; otherwise, step S83 is executed.

S8222, controlling to open the refrigerating air door and close the ice making air door.
S8223, controlling to close the ice making air door and the cold storage air door at the same time, and stopping refrigeration of the refrigeration system.
And S83, detecting whether the ice making chamber sends a refrigeration request instruction. If so, step S831 is performed, otherwise, step S832 is performed.
And S831, detecting whether the refrigerating chamber sends a refrigerating request command or not. If so, step S8311 is performed, otherwise, step S8312 is performed.
And S8311, controlling to open the ice making air door and the refrigerating air door simultaneously.

And S8322, controlling to close the ice making air door and the cold storage air door at the same time, and stopping refrigeration of the refrigeration system.
It should be noted that, according to the method provided in this embodiment, the refrigeration system of the refrigerator is controlled, so that the refrigeration cycle of the refrigerating compartment can be matched with the ice-making cycle of the ice-making compartment, and reference may be made to the schematic diagram of the refrigerating cycle of the refrigerating compartment and the ice-making cycle of the ice-making compartment shown in fig. 4. At the moment, the refrigeration process of the ice machine is less influenced by the refrigeration of the refrigerating chamber, the ice making efficiency and the ice making quantity can be improved, the ice making period is shortened, and the energy consumption of the refrigerator is reduced.
